Referring to fig. 1, an embodiment of the present invention provides a roll changing apparatus, which has a picking station and an unwinding station. At the pick-up station, the lifting and fixing of the end of the reserve strip of the reserve roll is mainly performed. And at the unwinding station, the actions of two aspects are mainly completed, namely unwinding the output working material belt by using the working material belt, cutting off the working material belt, replacing the working material belt by using the standby material belt, and connecting the end part of the lifted standby material belt with the cutting end of the working material belt.

The roll changing device comprises a carrying device 10, a picking device 20, an unreeling device 30 and a glue supplying device 40. The handling device 10 is movable along a first direction X between a pick-up station and an unwinding station. The handling device 10 is used for carrying the spare tape a. The pick-up device 20 is used to lift the end of the spare tape of the spare roll a on the carrying device 10 at the pick-up station, so that the carrying device 10 can fix the lifted end of the spare tape. Unwinding device 30 sets up at unreeling the station, and this unwinding device 30 is used for unreeling the output work material area to can cut off this work material area, and fix the end that cuts off in this work material area. The glue supply device 40 can move to the unreeling station along the first direction X. The tape supplying device 40 is used for supplying the tape to the unwinding device 30 when reaching the unwinding station.

When the carrying device 10 moves to the unwinding station, the carrying device is further configured to transfer the end portions of the standby material roll a and the standby material tape to the unwinding device 30 together, so that the unwinding device 30 sticks the adhesive tape between the end portion of the standby material tape and the cut end of the working material tape, and thus the connection between the standby material tape and the working material tape (i.e., splicing) is achieved.

It should be noted that the work material roll refers to a roll that is loaded on the unwinding device 30 and is unwound downstream to output the work material tape. The working material belt refers to a material belt which is unwound and output by a working material roll. The stock roll a is a roll that is carried by the carrying device 10 and used for replacing the work roll (i.e., the work roll is replaced with the stock roll after unwinding of the work roll is completed). The standby tape refers to a tape unwound from the standby roll a and outputted.

In the roll changing device, during the actual roll changing operation, firstly, the adhesive supplying device 40 moves to the unwinding station, and supplies the adhesive tape to the unwinding device 30. The handling device 10 is loaded with the reserve roll a and moves to the picking station, and the picking device 20 lifts the end of the reserve tape of the reserve roll a on the handling device 10, so that the handling device 10 holds the lifted end of the reserve tape, so that the end of the reserve tape is maintained in a state (for example, a vertical state as shown in fig. 1) convenient for the subsequent cutting of the end tape with the work tape.

When the work material roll on the unwinding device 30 is used up, the unwinding device 30 stops unwinding, and cuts the work material strip, and fixes the cut end of the work material strip. The unwinding device 30 winds the work material tape (i.e., the residual material tape between the cutting position and the work material roll after the work material tape is cut) connected to the work material roll onto the work material roll, and then discharges the work material roll on the unwinding device 30. Then, the carrying device 10 moves to the unwinding station (at this time, the end of the spare tape is fixed by the carrying device 10, so that the end of the spare tape is kept lifted), and the carrying device 10 transfers the spare roll a and the end of the spare tape together to the unwinding device 30, so that the end of the spare tape is butted against the cut end of the working tape. Then, the unwinding device 30 sticks the tape between the end of the spare tape and the cut end of the working tape, thereby realizing the connection between the spare tape and the working tape.

Therefore, the roll changing equipment can complete the procedures of providing adhesive tapes to the unwinding device 30, lifting the spare material belts on the spare material rolls A, connecting the end parts of the spare material belts with the cut ends of the working material belts and the like, further realize roll changing, has high automation degree and is beneficial to improving the roll changing efficiency. Moreover, the unwinding device 30 is used for rubberizing the cut end of the working material belt and the end of the spare material belt, so that the carrying device 10 only needs to transport the spare material belt A and fix the lifted end of the spare material belt, and the carrying device 10 does not need to receive the adhesive tape and complete rubberizing, thereby simplifying the action process of the carrying device 10, further greatly simplifying the structure of the carrying device 10, reducing the space occupied by the carrying device 10, enabling the carrying device 10 to move between the picking station and the unwinding station more flexibly and rapidly, and greatly improving the response speed. Further, due to the simplified structure of the handling device 10 and the reduced occupied space of the handling device 10, the spatial layout of other mechanisms (such as the picking device 20 and the like) is facilitated, the cooperation of the mechanisms is optimized, and the production efficiency and the operation stability are further improved to meet the production requirement of increasing production capacity.

In the embodiment, the glue supplying device 40 is mounted on the carrying device 10, so that the glue supplying device 40 moves along with the carrying device 10 along the first direction X. When the adhesive supplying device 40 moves to the unwinding device 30 along with the carrying device 10, the adhesive supplying device 40 supplies the adhesive tape to the unwinding device 30. Thus, the glue supply device 40 moves together with the carrying device 10, thereby avoiding the need of configuring two sets of power mechanisms and further simplifying the equipment structure.

It should be noted that, during transportation and handling of the backup roll a, the initial section of the backup tape on the backup roll a is likely to collide, oxidize, wet or be clamped, and the like, so that the quality of the initial section of the backup tape on the backup roll a is poor, that is, the initial section becomes a waste section. And, still be provided with the label on the initial section of the reserve material area on the reserve material book A, this label can adopt the mode mark coil stock information of two-dimensional code. Therefore, the scrap pieces need to be cut off at the time of use. In actual production, the waste section on the backup roll a loaded onto the handling device 10 may have been removed in a previous process, when the initial section of the backup belt of the backup roll a on the handling device 10 is not a waste section. Of course, the waste section on the backup roll a loaded onto the handling device 10 may not be removed, and the initial section of the backup strip of the backup roll a on the handling device 10 is the waste section.

When the starting section of the spare tape on the spare roll a is not a waste section, the end of the spare tape is referred to herein as the starting end of the spare tape, so that the end of the spare tape is simply lifted and fixed at the pick-up station. When the initial section of the spare material tape is a waste material section, the waste material section on the spare material roll a needs to be lifted and cut at the picking station, and then the cut end of the spare material tape after the waste material section is cut is fixed, so that the end of the spare material tape in this case refers to the cut end formed on the spare material tape after the waste material section is cut.

Referring to fig. 2 to 4, in an embodiment of the present invention, the carrying device 10 includes a base 11, and a loading shaft 12, an adsorbing assembly 14, and a cutting assembly 13 all disposed on the base 11. The base 11 can move along the first direction X between the pick-up station and the unwinding station, so as to realize the movement of the handling device 10 between the pick-up station and the unwinding station. The loading shaft 12 is used for loading the reserve roll a. The absorption component 14 and the cutting component 13 are arranged at intervals along the first direction X, and a cutting channel d for the lifted standby material belt to pass through is formed between the absorption component and the cutting component. The suction assembly 14 and the cutting assembly 13 can be controlled to approach or move away from each other. When the base 11 moves to the picking station, the absorption component 14 and the cutting component 13 approach each other along the first direction X to clamp the spare tape passing through the cutting channel d, so that the cutting component 13 cuts the spare tape, and the absorption component 14 absorbs and fixes the end of the cut spare tape.

Thus, when the standby tape of the standby material roll a needs to be lifted, first, the base 11 moves to the picking station, and the picking device 20 lifts the standby tape of the standby material roll a on the loading shaft 12, so that the lifted standby tape passes through the cutting passage d between the adsorption component 14 and the cutting component 13. Then, the suction member 14 and the cutting member 13 are brought close to each other until the passing backup tape is cut off, and the suction member 14 suction-fixes the end of the cut backup tape. At the moment, on one hand, the purpose of lifting the spare material belt and fixing the end part of the spare material belt is achieved; on the other hand, the purpose of cutting off the initial section of the spare material belt (the initial section of the spare material belt is a waste material section) is achieved.

It should be noted that, the adsorption component 14 and the cutting component 13 are close to each other and clamp the passing spare material belt, so that the end of the spare material belt is adsorbed and fixed while the spare material belt is cut off, and a cutting mechanism for cutting off the clamped spare material belt is not required to be additionally arranged, so that the equipment structure is further simplified, the occupied space is saved, and the spatial layout is convenient.

In a particular embodiment, the handling device 10 further comprises a pusher shoe 15, the pusher shoe 15 being movably connected to the base 11 in the axial direction of the loading shaft 12. The adsorption component 14 is arranged on the material pushing seat 15. When the base 11 moves to the unreeling station, the material pushing seat 15 can push the spare material roll a on the material loading shaft 12 and the end of the spare material belt adsorbed and fixed on the adsorption component 14 to the unreeling device 30 along the axial movement process of the material loading shaft 12, so that the end of the spare material roll a and the end of the spare material belt are together transferred to the unreeling device 30, and the end of the spare material belt and the cut end of the working material belt are connected through adhesive tape by the unreeling device 30. It should be noted that, because the standby material roll a and the suction assembly 14 move synchronously under the pushing action of the material pushing seat 15, the standby material roll a and the lifted end of the standby material tape are relatively stationary, so that the lifted end of the standby material tape is kept in a lifted state to be in butt joint with the cut end of the working material tape on the unwinding device 30.

Further, the carrying device 10 further includes a pushing driving assembly, which is disposed on the base 11 and is in driving connection with the pushing seat 15 to drive the pushing seat 15 to move along the axial direction of the loading shaft 12.

Optionally, the pushing driving assembly includes a pushing screw 152, a pushing screw nut, and a pushing driving member 151. The pushing screw 152 is rotatably connected to the base 11 around its axis, and the axial direction of the pushing screw 152 is parallel to the axial direction of the charging shaft 12. The pushing driving member 151 is mounted on the base 11 and is drivingly connected to the pushing screw 152 to drive the pushing screw 152 to rotate. The material pushing screw nut is in threaded connection with the material pushing screw 152 and is fixedly connected with the material pushing seat 15, so that the material pushing screw 152 can drive the material pushing screw nut to move along the axial direction of the charging shaft 12 when rotating, and further drive the material pushing seat 15 to move along the axial direction of the charging shaft 12. Alternatively, the pusher drive 151 may employ a motor.

Optionally, a guide rod 153 is mounted on the base 11, and an axial direction of the guide rod 153 is parallel to an axial direction of the charging shaft 12. The guide sleeve 154 is installed on the material pushing seat 15, and the guide rod 153 is slidably fitted in the guide sleeve 154, so that the movement of the material pushing seat 15 relative to the base 11 is guided by the sliding fit of the guide rod 153 and the guide sleeve 154.

In particular embodiments, the handling device 10 further comprises a first mounting seat 17 and a second mounting seat 18. The first installation seat 17 is fixedly connected to the base 11, and the cutting assembly 13 is arranged on the first installation seat 17. The second mounting seat 18 is movably connected to the pusher seat 15 along the first direction X. The suction assembly 14 is disposed on the second mounting seat 18 to be brought close to or away from the cutting assembly 13 by the second mounting seat 18.

Thus, when the base 11 moves to the picking station, after the spare tape of the spare material roll a on the loading shaft 12 is lifted by the picking device 20, the second mounting seat 18 is controlled to move along the first direction X relative to the pushing seat 15, so as to drive the adsorption component 14 to approach the cutting component 13 until the lifted spare tape is adsorbed and fixed by the adsorption component 14, and the cutting component 13 cuts off the spare tape, so as to form an end of the spare tape and an end of the cut waste material section at the cut-off position (at this time, the end of the spare tape and the end of the cut waste material section are both adsorbed and fixed by the adsorption component 14). When the base 11 moves to the unwinding station, the material pushing seat 15 is controlled to move towards the unwinding device 30 along the axial direction of the material loading shaft 12, so as to drive the standby material roll a on the material loading shaft 12 and the adsorption component 14 adsorbing and fixing the end part of the standby material strip to move towards the unwinding device 30 together until the standby material roll a and the end part of the standby material strip enter the unwinding device 30, so that the unwinding device 30 can paste the adhesive tape between the end part of the standby material strip and the cut end of the working material strip.

Further, the handling device 10 further comprises a first driving member 181. The first driving member 181 is mounted on the material pushing seat 15 and is in driving connection with the second mounting seat 18 to drive the second mounting seat 18 to move along the first direction X relative to the material pushing seat 15. Alternatively, the first driving member 181 may employ a cylinder.

Further, a first sliding block is arranged on the second mounting seat 18, a first sliding rail longitudinally extending along the first direction X is arranged on the pushing seat 15, and the first sliding block is slidably connected to the first sliding rail, so that the movement of the first sliding block along the first sliding rail guides the movement of the second mounting seat 18 relative to the pushing seat 15 along the first direction X.

It should be noted that, not limited to the first mounting seat 17 being fixed relative to the base 11, the second mounting seat 18 moves relative to the material pushing seat 15 along the first direction X, so that the suction assembly 14 and the cutting assembly 13 can move closer to or away from each other. In another embodiment, the second mounting seat 18 may also be fixedly connected to the material pushing seat 15, and the first mounting seat 17 is movably connected to the base 11 along the first direction X, so as to drive the cutting assembly 13 to be close to or far from the adsorption assembly 14 by controlling the first mounting seat 17 to move relative to the base 11 along the first direction X, thereby implementing cutting of the spare tape and adsorption fixation of the end of the spare tape. Of course, in another embodiment, the first mounting seat 17 may be movably connected to the base 11 along the first direction X, and the second mounting seat 18 may be movably connected to the material pushing seat 15 along the first direction X, so that the cutting assembly 13 and the suction assembly 14 are respectively driven to move close to or away from each other by controlling the first mounting seat 17 and the second mounting seat 18 to move simultaneously along the first direction X, and the cutting of the spare tape and the suction fixing of the end of the spare tape may also be achieved, which is not limited herein.

Specifically, in the embodiment, the cutting assembly 13 includes a mounting member 131, a pressing plate 132, a first elastic member 134, and a first cutting blade 133. The mounting member 131 is disposed on the first mounting seat 17, and the pressing plate 132 is disposed on a side of the mounting member 131 facing the suction assembly 14 and is movable toward or away from the suction assembly 14 in the first direction X with respect to the mounting member 131. The first elastic member 134 abuts between the pressing plate 132 and the mounting member 131 to provide a pre-load force that causes the pressing plate 132 to have a tendency to move away from the mounting member 131. The first cutter 133 is disposed on the mounting member 131, and in a process that the pressing plate 132 moves close to the mounting member 131 along the first direction X, the first cutter 133 can penetrate out of the first avoiding groove on the pressing plate 132 to the cutting channel d, and cut off the passing standby material tape.

In this way, when the lifted spare tape passes through the cutting passage d between the adsorption component 14 and the cutting component 13, the first mounting seat 17 and/or the second mounting seat 18 are controlled to move so as to drive the adsorption component 14 and the cutting component 13 to gradually approach each other along the first direction X, so that the spare tape is compressed between the adsorption component 14 and the pressing plate 132. As the cutting assembly 13 and the suction assembly 14 continue to approach each other, the pressing plate 132 moves closer to the mounting member 131 against the elastic force of the first elastic member 134, so that the first cutting knife 133 passes through the first escape slot on the pressing plate 132 to cut off the spare tape. After the spare tape is cut, the end of the waste section and the end of the spare tape are both adsorbed and fixed by the adsorption component 14. Alternatively, the first elastic member 134 may be a spring.

Further, the mounting member 131 is movably coupled to the first mounting seat 17 in the first direction X. The cutting assembly 13 also includes a first cutting drive 171 mounted on the first mounting block 17. The first cutting driving member 171 is drivingly connected to the mounting member 131 to drive the mounting member 131 to move toward or away from the suction assembly 14 along the first direction X relative to the first mounting seat 17. Alternatively, the first cutting drive 171 may be a pneumatic cylinder. In this way, when the lifted spare tape needs to be cut off, the first mounting seat 17 and/or the second mounting seat 18 are controlled to move along the first direction X, so as to bring the adsorption assembly 14 and the cutting assembly 13 close to each other until the adsorption assembly 14 and the pressing plate 132 of the cutting assembly 13 compress the spare tape together. Then, the first cutting driving element 171 drives the mounting element 131 to move toward the adsorption element 14 along the first direction X relative to the first mounting seat 17, and since the pressing plate 132 is stopped by the adsorption element 14 and cannot move continuously, the mounting element 131 drives the first cutting knife 133 to pass through the first avoiding groove on the pressing plate 132 (at this time, the compression amount of the first elastic element is increased), until the spare tape between the pressing plate 132 and the adsorption element 14 is cut off. After the spare material belt is cut off, the cutting component 13 and the adsorption component 14 are far away from each other and return along the first direction X, and then the first mounting seat 17 and/or the second mounting seat 18 are controlled to respectively return and move along the first direction X, so that the adsorption component 14 and the pressing plate 132 of the cutting component 13 are driven to separate from each other, and at the moment, the end part of the waste material section and the end part of the spare material belt are both adsorbed and fixed by the adsorption component 14.

Further, cutting assembly 13 still includes the guide bar, sets up the guiding hole that extends along first direction X on the installed part 131. The guide rod is slidably engaged with the guide hole, and one end of the guide rod is fixedly connected to the pressing plate 132, so that the movement of the pressing plate 132 with respect to the mounting member 131 is guided by the movement of the guide rod along the guide hole. Optionally, the first elastic element 134 is sleeved on the guide rod, and two opposite ends of the first elastic element are respectively abutted against the mounting element 131 and the pressing plate 132.

In particular embodiments, the suction assembly 14 includes a suction mount 141 disposed on the second mount 18. The suction base 141 has a first suction surface b for sucking the spare tape on a side facing the platen 132. Further, a second avoiding groove c for the first cutter 133 to cut is formed on the first absorption surface b. In this way, under the driving of the first mounting seat 17 and/or the second mounting seat 18, the pressing plate 132 and the first adsorption surface b of the adsorption seat 141 can press the spare tape together, and after the first cutter 133 cuts off the spare tape, both the end of the spare tape and the end of the cut waste segment are adsorbed and fixed on the first adsorption surface b of the adsorption seat 141. When the first cutter 133 cuts the spare tape, the first cutter 133 is retracted by the second retraction groove c formed on the first adsorption surface b, and the first cutter 133 is prevented from being damaged due to direct contact with the adsorption base 141. It should be noted that the second avoiding groove c divides the first adsorption surface b into a first sub-adsorption surface and a second sub-adsorption surface, the first sub-adsorption surface is located on one side of the second avoiding groove c close to the loading shaft 12, and the second sub-adsorption surface is located on one side of the second avoiding groove c far from the loading shaft 12. The first cutter 133 cuts the spare tape to form an end of the spare tape and an end of the cut waste segment at the cut portion, the end of the cut waste segment is adsorbed and fixed on the second sub-adsorption surface, and the end of the spare tape is adsorbed and fixed on the first sub-adsorption surface.

Further, the suction base 141 is movably coupled to the second mount base 18 in the first direction X. The suction assembly 14 also includes a second cutting drive 142 mounted on the second mount 18. The second cutting driving element 142 is drivingly connected to the suction base 141 to drive the suction base 141 to move toward or away from the mounting element 131 along the first direction X relative to the second mounting base 18. Alternatively, the second cutting drive 142 may be a pneumatic cylinder.

In this way, when the spare tape needs to be cut off, first, the first mounting seat 17 and/or the second mounting seat 18 are controlled to move along the first direction X relative to the material pushing seat 15 to drive the adsorption component 14 and the cutting component 13 to approach each other until the pressing plate 132 of the cutting component 13 presses and holds the spare tape on the first adsorption surface b of the adsorption seat 141. Then, the first cutting driving member 171 drives the mounting member 131 to move toward the suction assembly 14 along the first direction X relative to the first mounting seat 17, and at the same time, the second cutting driving member 142 drives the suction seat 141 to move toward the cutting assembly 13 along the first direction X relative to the second mounting seat 18, so that the first cutter 133 penetrates out of the first avoiding groove on the pressing plate 132 into the second avoiding groove c on the first suction surface b to cut off the spare tape (after the spare tape is cut off, the end portion of the spare tape and the end portion of the cut waste material segment are both fixed on the first suction surface b by suction). After the spare tape is cut, the first cutting driving member 171 drives the mounting member 131 to move away from the suction assembly 14 and return along the first direction X relative to the first mounting seat 17, and the second cutting driving member 142 drives the suction seat 141 to move away from the cutting assembly 13 and return along the first direction X relative to the second mounting seat 18. Then, the first mounting seat 17 and/or the second mounting seat 18 are controlled to move back relative to the material pushing seat 15 along the first direction X, so that the suction seat 141 of the suction assembly 14 is separated from the pressing plate 132 of the cutting assembly 13 (at this time, the first suction surface b of the suction seat 141 keeps suction-fixing the end of the spare tape and the end of the waste material segment).

In one embodiment, the handling device 10 further comprises a centering assembly 16, wherein the centering assembly 16 comprises a turntable 164, a connecting plate 165, and a centering roller 166. The turntable 164 is rotatably connected to the pusher shoe 15 about its own axis and is arranged coaxially with the charging shaft 12. The connecting plate 165 is fixedly connected to the turntable 164, and the swing roller 166 is rotatably connected to the connecting plate 165 around its axis and located between the loading shaft 12 and the cutting channel d for the lifted spare tape to pass around. In this way, the control turntable 164 is rotated to drive the leveling roller 166 to abut against the passing standby material tape, so as to adjust the spatial angle of the lifted standby material tape, so that the standby material tape from the standby material roll a to the cutting channel d is in a required state (for example, a vertical state), so that the standby material tape is cut off by the first cutter 133, and the end of the standby material tape and the cut-off end of the working material tape are connected.

Further, the centering assembly 16 further includes a centering driver, a driving pulley 161, a driven pulley 163, and a transmission belt 162. The centering drive is mounted on the stripper shoe 15, the driving pulley 161 is mounted on the output shaft of the centering drive, and the driven pulley 163 is mounted on the turntable 164. The transmission belt 162 is sleeved between the driving pulley 161 and the driven pulley 163, so that when the swing driving element drives the driving pulley 161 to rotate, the driving pulley 161 drives the driven pulley 163 to rotate through the transmission belt 162, and the driven pulley 163 drives the turntable 164 to rotate, thereby driving the swing roller 166 to adjust the space angle of the lifted spare material belt. Alternatively, the yaw drive may employ an electric motor.

It should be noted that, in the conveying device in the prior art, not only the end of the lifted spare material tape needs to be fixed, but also the adhesive tape needs to be received, and the received adhesive tape is adhered to the end of the lifted spare material tape, and the like, which results in a complicated structure of the conveying device in the prior art and a large occupied space, and on one hand, the operation efficiency of the conveying device is reduced, thereby reducing the efficiency of automatic roll change; on the other hand, other devices need to avoid the conveying device, so that the design difficulty of the other devices on the spatial layout is increased. In order to solve these problems, the present invention provides an unwinding device 30, please refer to fig. 5 to 8, in which the unwinding device 30 includes an unwinding shaft 32, a splicing mechanism 33 and a discharging mechanism 34. The unwinding shaft 32 is used for loading the work material roll and driving the work material roll thereon to rotate so as to unwind the output work material belt to the belt splicing mechanism 33, so that the work material belt is conveyed downstream after passing through the belt splicing mechanism 33, and further the work material belt is conveyed downstream. The splicing device 33 is capable of receiving the adhesive tape supplied by the adhesive supply device 40 on the one hand and of cutting off the passing work tape on the other hand. The blanking mechanism 34 is used to discharge the work material roll on the discharge reel 32 after the splicing mechanism 33 cuts the work material tape.

The handling device 10 is used to transfer the stock roll a to the unwinding shaft 32 and the lifted end of the stock tape to the splicing mechanism 33 when moving to the unwinding station. The splicing mechanism 33 is also used for sticking the adhesive tape between the end part of the spare material tape and the cut-off end of the working material tape, so that splicing of the working material tape and the spare material tape is realized.

In this way, the handling device 10 lifts the strip start a of the reserve strip of the reserve roll a on the loading shaft 12 by the pick-up device 20 at the pick-up station and draws out the waste section of the reserve strip. The cutting assembly 13 cuts off the waste material segment of the lifted spare tape by the first cutter 133, and the end of the spare tape with the waste material segment cut off is adsorbed and fixed on the first adsorption surface b of the adsorption base 141.

When unwinding of the work material roll on the unwinding shaft 32 of the unwinding device 30 is completed, first, the unwinding shaft 32 stops unwinding, and the splicing mechanism 33 cuts off the passing work material tape. After the working material tape is cut, the unwinding shaft 32 rotates reversely to wind the residual material tape between the unwinding shaft 32 and the cut part of the working material tape, and the blanking mechanism 34 is used to discharge the working material roll on the unwinding shaft 32 (the working material roll at this time is an empty cylinder and the residual material tape wound on the empty cylinder). Then, the carrying device 10 moves to the unwinding station, and the material pushing seat 15 pushes the spare material roll a on the material loading shaft 12 and the lifted end of the spare material tape to the tape splicing mechanism 33, so that the tape splicing mechanism 33 sticks the adhesive tape between the cut end of the working material tape and the end of the spare material tape, i.e. splicing the working material tape and the spare material tape is realized. Finally, the handling device 10 leaves the unwinding station, and the standby material roll a on the unwinding shaft 32 is a new work material roll, which is continuously unwound downstream by the unwinding shaft 32 to output the work material tape.

In the embodiment, the carrying device 10 further includes a first driving mechanism, which is drivingly connected to the base 11. The first driving mechanism is used for driving the base 11 to move along a first direction X, so that the base 11 passes through the picking station and the unreeling station. The first driving mechanism is further configured to drive the base 11 to move along a second direction Y parallel to the axial direction of the loading shaft 12, so as to drive the loading shaft 12 to axially abut against or separate from the unreeling shaft 32 of the unreeling device 30 at the unreeling station. In this way, when the first driving mechanism drives the base 11 to move along the second direction Y until the loading shaft 12 is axially abutted with the unwinding shaft 32, the stock roll on the loading shaft 12 can be pushed onto the unwinding shaft 32 by the material pushing seat 15. Optionally, the second direction Y is perpendicular to the first direction X.

In particular embodiments, the splicing mechanism 33 includes a first splicing assembly 331 and a second splicing assembly 332. The first splicing assembly 331 and the second splicing assembly 332 are both disposed on the first mounting frame 31. The first tape splicing assembly 331 and the second tape splicing assembly 332 are arranged at intervals along the first direction X, and a tape splicing space e is formed between the first tape splicing assembly 331 and the second tape splicing assembly 332. The splicing space e is used for the working material strip which is wound out from the working material roll on the unwinding shaft 32 to pass through. The first splicing assembly 331 and the second splicing assembly 332 can be controlled to approach or depart from each other along the first direction X.

The first tape splicing member 331 has a first side f1 and a second side f2, the first side f1 has a cutting portion 3315 for cutting the work material tape, and the second side f2 is for adsorbing the adhesive tape supplied from the adhesive supplying device 40. The first splicing assembly 331 is controllably switchable between a first state (see fig. 7) and a second state (see fig. 8). When the first splicing assembly 331 is in the first state, the first side surface f1 and the second splicing assembly 332 are opposite to each other in the first direction X, so that the cutting portion 3315 on the first side surface f1 can press the working material belt against the second splicing assembly 332 and cut off the pressed working material belt in the process that the first splicing assembly 331 and the second splicing assembly 332 approach each other along the first direction X.

Further, when the carrying device 10 moves to the unwinding station, the material pushing seat 15 pushes the adsorption seat 141, which adsorbs the end of the spare tape, to the tape receiving space e, and the first adsorption surface b of the adsorption seat 141 adsorbs the cut end of the working tape located in the tape receiving space e, so that the cut end of the working tape and the end of the spare tape are adsorbed and fixed by the first adsorption surface b of the adsorption seat 141.

When the first tape splicing assembly 331 is in the second state, the second side surface f2 is opposite to the second tape splicing assembly 332 in the first direction X, so that the adhesive tape on the second side surface f2 can be adhered between the cut end of the working tape and the end of the spare tape, which are sucked and fixed by the first suction surface b of the suction base 141, in the process that the first tape splicing assembly 331 approaches the second tape splicing assembly 332.

Thus, when the unwinding of the work material roll on the unwinding shaft 32 is completed, the unwinding shaft 32 stops unwinding, the first tape splicing assembly 331 is in the first state (i.e., the first side surface f1 of the first tape splicing assembly 331 is opposite to the second tape splicing assembly 332 in the first direction X), and the first tape splicing assembly 331 and the second tape splicing assembly 332 are controlled to approach each other along the first direction X until the cutting portion 3315 on the first side surface f1 presses the work material roll against the second tape splicing assembly 332 and cuts the work material roll. Then, the first splicing component 331 and the second splicing component are far away from each other along the first direction X. Then, the carrying device 10 moves to the unwinding station, and the material pushing seat 15 is used to push the spare material roll a on the material loading shaft 12 to the unwinding shaft 32, and push the adsorption seat 141 adsorbing the end of the spare material tape to the tape splicing space e, so that the adsorption seat 141 adsorbs the cut end of the working material tape on the first adsorption surface b, that is, the cut end of the working material tape and the cut end of the spare material tape are adsorbed and fixed on the first adsorption surface b at this time. At this time, the first splicing member 331 is switched to the second state such that the second side surface f2 of the first splicing member 331 is opposed to the first suction surface b of the suction holder 141 entering the splicing space e in the first direction X. Then, the first tape splicing assembly 331 is controlled to move toward the second tape splicing assembly 332 in the first direction X until the second side surface f2 of the second tape splicing assembly 332 abuts against the first adsorption surface b of the adsorption base 141, so that the adhesive tape adsorbed on the second side surface f2 is adhered between the cut end of the working tape adsorbed on the first adsorption surface b and the end of the spare tape, that is, the cut end of the working tape is connected with the end of the spare tape through the adhesive tape.

Specifically, in the embodiment, the first splicing assembly 331 includes a first moving base 3311, a first moving driver 3312 and a first tape carrier 3314. The first moving base 3311 is movably coupled to the first mounting block 31 in the first direction X. The first rubberizing member 3314 is rotatably coupled to the first movable base 3311. The first movable driving member 3312 is disposed on the first mounting frame 31 and is drivingly connected to the first movable base 3311, such that the first movable driving member 3312 can drive the first movable base 3311 to move along the first direction X relative to the first mounting frame 31. The first movable base 3311 drives the first tape splicing component 3314 to approach or leave the second tape splicing component 332 in the process of moving along the first direction X relative to the first mounting block 31. Two side surfaces of the first tape member 3314 serve as the first side surface f1 and the second side surface f2 described above, respectively. During the rotation of the first tape member 3314 relative to the first movable base 3311, the first side surface f1 and the second side surface f2 can alternately oppose the second tape splicing assembly 332 in the first direction X, so as to switch between the first state and the second state. Alternatively, the first moving drive 3312 may be a pneumatic cylinder.

Further, the first splicing assembly 331 further includes a first telescopic member 3313, and the first telescopic member 3313 is disposed on the first movable base 3311. The first telescopic member 3313 has a telescopic first telescopic end h2, and the first telescopic end h2 is hinged to the first rubberizing member 3314. Thus, when the first telescopic end h2 of the first telescopic member 3313 is telescopic, the first tape member 3314 can be driven to rotate relative to the first movable base 3311, so that the first tape member 3314 can be switched between the first state and the second state. Alternatively, the first telescopic member 3313 may be a cylinder.

Specifically, in the embodiment, the cutting portion 3315 includes a pressing member 3318, a second cutting blade 3316 and a second elastic member 3317. The pressing member 3318 is disposed on the first side surface f1 of the first tape member 3314, and is movable toward or away from the first side surface f1 along the first direction X. The second elastic member 3317 abuts between the first rubberizing member 3314 and the pressing member 3318 for providing a pre-tightening force for the pressing member 3318 to have a movement tendency away from the first side surface f 1. The second cutter 3316 is connected to the first side surface f1 of the first rubberizing part 3314, so that the second cutter 3316 can penetrate out to the tape splicing space e from the third avoiding groove on the pressing part 3318 and cut off the work tape in the process that the pressing part 3318 moves close to the first rubberizing part 3314.

Thus, when the work material tape needs to be cut, the first tape splicing assembly 331 and the second tape splicing assembly 332 approach each other along the first direction X, so that the pressing member 3318 presses the work material tape against the second tape splicing assembly 332. As the first splicing assembly 331 and the second splicing assembly 332 continue to move closer to each other along the first direction X, the pressing member 3318 is pressed by the second splicing assembly 332 to move closer to the first rubberizing member 3314 (while the compression of the second elastic member 3317 increases), so that the second cutter 3316 passes through the third escape slot on the pressing member 3318, thereby cutting off the work material strip between the pressing member 3318 and the second splicing assembly 332. After the work material tape is cut, the unwinding shaft 32 is rotated to wind the residual material tape between the empty cartridge and the second cutter 3316 on the empty cartridge, and the empty cartridge on the unwinding shaft 32 is unloaded by the discharging assembly. The first splicing assembly 331 and the second splicing assembly 332 move away from each other such that the pressing member 3318 is separated from the second splicing assembly 332. Alternatively, the second elastic member 3317 may be a spring.

Optionally, the cut-out portion 3315 further comprises a guide post slidably attached to the first tape member 3314, the guide post having an axial direction parallel to the first direction X. The pressing member 3318 is fixedly attached to one end of the guide post so as to guide the movement of the pressing member 3318 relative to the first tape member 3314 by the guide post. Further, the second elastic component 3317 is sleeved on the guide post, and two opposite ends thereof are respectively abutted against the first rubberizing component 3314 and the pressing component 3318.

In specific embodiments, the second tape splicing assembly 332 has a third side g1 and a fourth side g2, and the fourth side g2 is used for absorbing adhesive tapes. The second splicing assembly 332 is controllably switchable between a third state (see fig. 7) and a fourth state (see fig. 8).

When the second tape splicing component 332 is in the third state, the third side g1 is opposite to the first side f1 in the first direction X, so that in the process that the first tape splicing component 331 and the second tape splicing component 332 approach each other, the third side g1 and the cutting portion 3315 on the first side f1 can press the work material tape together, and the second cutter 3316 of the cutting portion 3315 cuts the work material tape. When the second tape splicing assembly 332 is in the fourth state, the fourth side g2 is opposite to the second side f2 in the first direction X, so that in the process that the second tape splicing assembly 332 approaches to the first tape splicing assembly 331, the adhesive tape on the fourth side g2 can be adhered to the cut end of the working tape and the end of the spare tape on the second side f2, thereby connecting the cut end of the working tape and the end of the spare tape.

Further, the second belt splicing assembly 332 comprises a second movable base 3321 and a second rubberizing member 3324 rotatably connected to the second movable base 3321. The second movable base 3321 is movably coupled to the first mounting frame 31 in the first direction X. In the process that the second movable seat 3321 moves along the first direction X relative to the first mounting frame 31, the second tape member 3324 is driven to move close to or away from the first tape splicing assembly 331. Two sides of the second sticker 3324 serve as a third side g1 and a fourth side g2, respectively. During the rotation of the second rubberizing element 3324 with respect to the second movable seat 3321, the third side g1 and the fourth side g2 can alternately face the first splicing assembly 331 in the first direction X, so as to switch the second rubberizing element 3324 between the third state and the fourth state.

Further, a fourth avoiding groove g3 for the second cutter 3316 to extend into is formed in the third side surface g1 of the second rubberizing part 3324, that is, the fourth avoiding groove g3 is used for avoiding the second cutter 3316 when the working material tape is cut off, so that the second cutter 3316 is prevented from being damaged due to direct contact with the second rubberizing part 3324.

Optionally, a protection gasket is disposed on a surface of the third side g1 of the second rubberizing member 3324, which is in contact with the work material tape, so that the work material tape is protected by the protection gasket to avoid crushing the work material tape. Of course, the surface of the pressing member 3318 contacting the work material belt may also be provided with a protective pad to prevent the work material belt from being crushed.

Further, the second belt splicing assembly 332 further comprises a second telescopic member 3323, and the second telescopic member 3323 is disposed on the second movable seat 3321. The second telescopic member 3323 has a telescopic second telescopic end h4, and the second telescopic end h4 is hinged to the second rubberizing member 3324. Thus, when the second telescopic end h4 of the second telescopic member 3323 is telescopic, the second adhesive piece 3324 can be driven to rotate relative to the second movable seat 3321, so that the second adhesive piece 3324 is switched between the third state and the fourth state. Alternatively, the second telescopic member 3323 may be a cylinder.

Further, the second splicing assembly 332 further comprises a second movement drive 3322. The second movable driving member 3322 is disposed on the first mounting frame 31 and is drivingly connected to the second movable base 3321. The second movable driving member 3322 is configured to drive the second movable base 3321 to move along the first direction X relative to the first mounting frame 31, so that the second movable base 3321 drives the second adhesive piece 3324 to move close to or away from the first tape splicing assembly 331 along the first direction X. Alternatively, the second movement drive 3322 may be a pneumatic cylinder.

Further, a second slide rail is disposed on the first mounting frame 31, and the second slide rail extends lengthwise along the first direction X. The first moving base 3311 is provided with a second sliding block, which is connected with the second sliding rail in a sliding manner. The second movable seat 3321 is provided with a third sliding block, and the third sliding block is connected with the second sliding rail in a sliding manner. In this way, the movement of the first moving base 3311 relative to the first mounting bracket 31 along the first direction X is guided by the movement of the second slider along the second slide rail. The movement of the second movable base 3321 in the first direction X with respect to the first mounting frame 31 is guided by the movement of the third slider along the second slide rail.

In particular embodiments, the splicing mechanism 33 further includes a suction belt assembly disposed on the second mounting frame 334. The suction belt assembly has a suction belt portion 333, and the suction belt portion 333 is used for sucking the cut end of the work material belt in the belt splicing space e and is controlled to move away from or reach the belt splicing space e to drive the cut end of the work material belt to leave or reach the belt splicing space e. Thus, after the second cutter 3316 cuts the working material tape, the tape suction part 333 moves to the tape splicing space e to suck the cut end of the working material tape, and then the cut end of the working material tape is carried away from the tape splicing space e, so that the cut end of the working material tape is prevented from shaking randomly; on the other hand, the suction base 141 is retracted from the belt joining space e.

Alternatively, the suction belt portion 333 may employ a suction cup. The suction belt part 333 may swing to reach or leave the belt joining space e, but in other embodiments, the suction belt part 333 may also move linearly to reach or leave the belt joining space e, and the present invention is not limited thereto.

Further, when the material pushing seat 15 drives the suction seat 141 to enter the tape splicing space e, the first suction surface b of the suction seat 141 faces the first tape splicing element 331, so that the second side surface f2 of the first tape splicing element 331 (at this time, the first tape splicing element 331 is in the second state) is opposite to the first suction surface b of the suction seat 141 in the first direction X. When the suction belt part 333 reaches the splicing space e with the cut end of the work tape carried thereon, the suction base 141 can suck the cut end of the work tape. Further, in the process that the first tape splicing assembly 331 moves toward the suction holder 141 in the first direction X, the adhesive tape on the second side surface f2 can be adhered to the cut end of the working tape and the end of the spare tape on the first suction surface b.

Specifically, in the embodiment, the unwinding device 30 further includes a third mounting frame 321 and an unwinding driving mechanism 38 disposed on the third mounting frame 321, and the unwinding driving mechanism 38 is drivingly connected to the unwinding shaft 32 to drive the unwinding shaft 32 to rotate. The unwinding shaft 32 rotates to rotate the work material roll thereon, thereby unwinding the output work material tape. Of course, the unwinding driving mechanism 38 may also drive the unwinding shaft 32 to rotate in the reverse direction during splicing, so as to wind the remnant tape connected to the work material roll after the work material tape is cut, onto the work material roll. It should be noted that the unwinding driving mechanism 38 may be implemented by a relatively mature technology, and is not limited herein.

Specifically, in the embodiment, the blanking mechanism 34 includes a third moving seat 341, a swing arm 342, and a clamping jaw assembly 343. One end of the swing arm 342 is rotatably connected to the third movable base 341, and the jaw assembly 343 is disposed at the other end of the swing arm 342. The third moving seat 341 is used for driving the swing arm 342 and the clamping jaw assembly 343 on the swing arm 342 to move along the axial direction of the unreeling shaft 32. The gripper assembly 343 is used to grip the roll of work material on the unwind shaft 32 as it follows the swing arm 342 to the unwind shaft 32. Alternatively, an air cylinder may be used to drive the third movable base 341 to move in the axial direction of the unreeling shaft 32. The swing arm 342 is mounted on the third movable base 341 through a swing shaft 344, and the swing shaft 344 can be driven by a motor to rotate, so as to drive the swing arm 342 to swing.

In this way, when the work material roll on the unwinding shaft 32 needs to be unloaded, first, the swing arm 342 is controlled to swing relative to the third movable base 341 until the clamping jaw assembly 343 reaches the unwinding shaft 32. Then, the third moving seat 341 moves along the axial direction of the unwinding shaft 32 until the clamping jaw assembly 343 is driven to move along the axial direction of the unwinding shaft 32 to the position of the work material roll on the unwinding shaft 32. Then, the clamping jaw assembly 343 clamps the work material roll, and then returns along the axial direction of the unwinding shaft 32 under the driving of the third moving seat 341 until the empty material roll is drawn out from the unwinding shaft 32. Finally, the swing arm 342 is controlled to swing relative to the third movable base 341 and return to the initial position, so as to drive the clamping jaw assembly 343 clamping the work material roll to return to the initial position and release the work material roll.

It should be noted that the blanking mechanism 34 drives the clamping jaw assembly 343 to reach or leave the unwinding shaft 32 by swinging the swing arm 342, so as to unload the work material roll on the unwinding shaft 32. Therefore, the blanking mechanism 34 does not need to be provided on the conveying device 10 to move, so that the structure of the conveying device 10 is further simplified, and the operation efficiency of the conveying device 10 is improved.

Further, the unwinding device 30 further includes an empty cartridge collecting mechanism 80, and the empty cartridge collecting mechanism 80 is used for receiving the empty cartridge released by the clamping jaw assembly 343.

It should be noted that the roll changer further includes a mounting substrate (not shown), and the first mounting rack 31, the second mounting rack 334, and the third mounting rack 321 are all fixedly connected to the mounting substrate. The third moving base 341 is movably attached to the mounting substrate in the axial direction of the unreeling shaft 32, for example, the third moving base 341 is mounted on the mounting substrate by a slide block assembly.

The following describes the procedure of the strip: when the unwinding of the work material roll is completed, the unwinding shaft 32 stops unwinding, the first tape splicing assembly 331 is in the first state, and the second tape splicing assembly 332 is in the third state, that is, the pressing member 3318 is opposite to the third side g1 of the second rubberizing member 3324 in the first direction X. Then, the first movable base 3311 and the second movable base 3321 are controlled to drive the first rubberizing part 3314 and the second rubberizing part 3324 to move close to each other along the first direction X, so that the pressing part 3318 and the third side g1 of the second rubberizing part 3324 press and fix the passing work tape together. As the first tape member 3314 and the second tape member 3324 continue to approach each other along the first direction X, the first tape member 3314 drives the second cutter 3316 to pass through the third avoiding groove on the pressing member 3318 until the second cutter passes through the fourth avoiding groove g3, so as to cut off the work tape. Then, the unwinding shaft 32 is controlled to drive the working material roll to rotate, so as to wind the residual material belt between the working material roll and the second cutter 3316 on the working material roll, and then the blanking assembly is used to unload the working material roll on the unwinding shaft 32. The suction belt portion 333 is controlled to move to reach the belt splicing space e to suck the cut end of the work material belt. The first movable base 3311 and the second movable base 3321 are controlled to drive the first rubberized part 3314 and the second rubberized part 3324 to move away from each other along the first direction X, so that the pressing part 3318 is separated from the second rubberized part 3324. The suction belt portion 333 is controlled to move away from the belt joining space e so that the cut end of the work material belt follows the suction belt portion 333 away from the belt joining space e.

Then, the carrying device 10 moves to the unwinding station, and uses the material pushing seat 15 to push the standby material roll a on the material loading shaft 12 onto the unwinding shaft 32, and simultaneously pushes the suction seat 141 (at this time, the end of the standby material tape is sucked and fixed on the first suction surface b of the suction seat 141) to the tape connecting space e (i.e., between the first tape connecting assembly 331 and the second tape connecting assembly 332), where the first suction surface b of the suction seat 141 faces the first tape connecting assembly 331. Then, the suction belt portion 333 is controlled to move to the belt joining space e so that the cut end of the working tape reaches the first suction surface b of the suction base 141 and is sucked and fixed by the first suction surface b of the suction base 141, and at this time, both the cut end of the working tape and the end of the spare tape are sucked and fixed by the first suction surface b. After the cut end of the work tape is adsorbed by the first adsorption surface b, the adsorption part 333 stops adsorbing the cut end of the work tape and moves away from the tape splicing space e.

Then, the first tape splicing assembly 331 is in the second state, such that the second side surface f2 of the first tape pasting component 3314 (at this time, the second side surface f2 is adsorbed and fixed with the tape provided by the tape supply device 40) is opposite to the first adsorption surface b of the adsorption base 141 in the first direction X, and the first moving base 3311 is controlled to drive the first tape pasting component 3314 to move toward the adsorption base 141 along the first direction X until the second side surface f2 of the first tape pasting component 3314 abuts against the first adsorption surface b of the adsorption base 141, such that the tape on the second side surface f2 is pasted between the cut end of the working tape and the end of the standby tape. Then, the first adsorption surface b of the adsorption seat 141 stops adsorbing the cut end of the working tape and the end of the standby tape, and the material pushing seat 15 drives the adsorption seat 141 to exit the tape splicing space e. At this time, the tape is stuck to the same side of the cut end of the working tape and the end of the spare tape, and the tape is adsorbed and fixed to the second side surface f2 of the first tape member 3314.

Then, the second tape splicing assembly 332 is in a fourth state, such that the fourth side g2 of the second adhesive piece 3324 (the fourth side g2 is adhered with the adhesive tape provided by the adhesive supplying device 40) is opposite to the second side f2 of the first adhesive piece 3314 in the first direction X. The first seat 3311 and the second that remove of control 3321 drive first rubberizing part 3314 and second rubberizing part 3324 and are close to each other along first direction X, until first rubberizing part 3314 and second rubberizing part 3324 support and lean on, make the sticky tape on the fourth side g2 of second rubberizing part 3324 paste to between the end of cutting of work material area and the tip of reserve material area, the both sides of the end of cutting of work material area and the tip of reserve material area all are pasted with the sticky tape this moment, make the connection of the end of cutting of work material area and the tip of reserve material area more firm. Finally, the second side f2 of the first sticker 3314 stops suctioning the tape thereon, and the fourth side g2 of the second sticker 3324 also stops suctioning the tape thereon. The first and second

movable bases

3311 and 3321 are controlled to move the first and

second stickers

3314 and 3324 away from each other in the first direction X until they return to the initial position. At this time, the backup roll a on the unwinding shaft 32 is switched to the work roll, and the work tape is unwound downstream. It should be noted that the sequence of actions of the components in the tape splicing process is not limited to this, as long as the cut end of the working tape can be connected with the end of the spare tape, and the operation is not limited herein.

Referring to fig. 9 to 11, in an embodiment of the present invention, the glue supply device 40 includes a support frame 41, and a tape unwinding mechanism 42, a glue suction platform 43, a glue pulling mechanism 44 and a glue cutting mechanism 45 all disposed on the support frame 41. The supporting frame 41 is used for driving the glue supply device 40 to move to the unreeling station along the first direction X. The tape unwinding mechanism 42 is used for outputting a tape. The adhesive suction platform 43 is located downstream of the tape unwinding mechanism 42 and is used for sucking or releasing the passing tape. When the supporting frame 41 drives the glue supplying device 40 to move to the unwinding station along the first direction X, the first glue applying part 3314 or the second glue applying part 3324 of the unwinding device 30 is located at the downstream side of the glue sucking platform 43. The tape pulling mechanism 44 is configured to pull the tape on the tape suction platform 43 downstream onto the first tape member 3314 or the second tape member 3324 of the unwinding device 30. The tape cutting mechanism 45 is configured to cut off a tape strip from between the tape suction platform 43 and the first tape member 3314 or the second tape member 3324 of the unwinding device 30, and at this time, a portion of the tape strip located at the first tape member 3314 or the second tape member 3324 of the unwinding device 30 is the above tape.

Thus, when the tape needs to be provided to the first tape-sticking member 3314 or the second tape-sticking member 3324 of the unwinding device 30, firstly, the supporting frame 41 drives the tape-supplying device 40 to move to the unwinding station along the first direction X, so that the first tape-sticking member 3314 or the second tape-sticking member 3324 of the unwinding device 30 is located at the downstream side of the tape-sucking platform 43. Then, the tape pulling mechanism 44 picks up the tape strip on the tape sucking platform 43 and moves toward the first tape member 3314 or the second tape member 3324 of the unwinding device 30, thereby pulling the tape strip onto the first tape member 3314 or the second tape member 3324 of the unwinding device 30. Then, the tape cutting mechanism 45 cuts the tape strip from a position between the tape suction platform 43 and the first tape member 3314 or the second tape member 3324 of the unwinding device 30, and at this time, a portion of the tape strip located at the first tape member 3314 or the second tape member 3324 of the unwinding device 30 is the above tape. Finally, the tape pulling mechanism 44 releases the tape onto the first tape member 3314 or the second tape member 3324 of the unwinding device 30, so as to supply the tape to the first tape member 3314 or the second tape member 3324 of the unwinding device 30.

It should be noted that, in order to provide the second side f2 of the first rubberizing member 3314 and the fourth side g2 of the second rubberizing member 3324 of the unwinding device 30 with adhesive tapes, the adhesive tapes are provided. When the supporting frame 41 drives the glue supplying device 40 to move to the unreeling station, firstly, the glue supplying device 40 moves to the position where the glue sucking platform 43 and the first glue applying part 3314 are aligned in the second direction Y along the first direction X, that is, the first glue applying part 3314 is located on the downstream side of the glue sucking platform 43, and at this time, the glue supplying device 40 can supply glue to the second side surface f2 of the first glue applying part 3314. Then, the glue supplying device 40 moves along the first direction X to a position where the glue sucking platform 43 is aligned with the second glued part 3324 in the second direction Y, that is, the second glued part 3324 is located at the downstream side of the glue sucking platform 43, and at this time, the glue supplying device 40 can supply glue on the fourth side g2 of the second glued part 3324. Of course, in other embodiments, the glue supplying device 40 may also supply glue to the fourth side g2 of the second gluing part 3324 first, and then supply glue to the second side f2 of the first gluing part 3314, which is not limited herein. Since the processes of supplying the glue to the second side f2 of the first sticker 3314 and the fourth side g2 of the second sticker 3324 are similar, the process of supplying the glue to the second side f2 of the first sticker 3314 will be described as an example.

In one embodiment, the tape pulling mechanism 44 includes a pick-up driving assembly and a tape picking portion 443. The pickup driving assembly includes a fourth moving base 441 and a rotating rod 442. The fourth movable base 441 is movably coupled to the supporting frame 41 in a second direction Y perpendicular to the first direction X. The rotating rod 442 is disposed on the fourth movable seat 441 and is rotatable about a pivot axis relative to the fourth movable seat 441. The tape picking portion 443 is disposed at the first end 4421 of the rotating rod 442 for picking up or releasing the tape. Alternatively, the fourth movable base 411 may be driven by an electric cylinder, an air cylinder, a lead screw pair, or the like, relative to the supporting frame 41 along the second direction Y.

In the process that the fourth movable base 441 moves relative to the supporting frame 41 along the second direction Y, the tape picking portion 443 can be driven to move between the tape sucking platform 43 and the first tape-sticking member 3314 of the unwinding device 30. In the process that the rotating rod 442 rotates around the pivot axis, the tape picking portion 443 positioned at the tape suction platform 43 can be driven to abut against or separate from the tape suction platform 43, so as to pick up the tape on the tape suction platform 43; or the tape picking portion 443 of the first tape applying member 3314 of the unwinding device 30 can be driven to abut against or separate from the second side surface f2 of the first tape applying member 3314, so as to release the tape onto the second side surface f2 of the first tape applying member 3314. Optionally, the second direction Y is perpendicular to the pivot axis. The pivot axis is parallel to the first direction X.

Thus, when the tape needs to be supplied to the first tape-sticking member 3314 of the unwinding device 30, firstly, the tape-supplying device 40 moves to the unwinding station along the first direction X, so that the first tape-sticking member 3314 of the unwinding device 30 is located at the downstream side of the tape-sucking platform 43. Then, the fourth moving seat 441 drives the tape picking portion 443 to move onto the glue sucking platform 43 along the second direction Y, and the tape picking portion 443 is abutted against the glue sucking platform 43 (the rotating rod 442 drives the tape picking portion 443 to descend in the embodiment shown in fig. 10) under the driving of the rotating rod 442, so that the tape picking portion 443 picks the tape of the tape on the glue sucking platform 43. Then, the tape pickup portion 443 is separated from the adhesive suction platform 43 by the rotation of the rotation rod 442 (the rotation of the rod 442 lifts the tape pickup portion 443 in the embodiment shown in fig. 10), so that the tape is taken away from the adhesive suction platform 43. Then, the fourth moving base 441 drives the tape picking portion 443 to move along the second direction Y to the second side f2 of the first adhesive member 3314, so that the tape picking portion 443 pulls the tape to the second side f2 of the first adhesive member 3314. Then, the rotating rod 442 drives the tape picking portion 443 against the second side f2 of the first tape member 3314, so that the tape picking portion 443 releases the tape onto the second side f2 of the first tape member 3314. Then, the adhesive suction platform 43 sucks the passing adhesive tape strip, and the adhesive tape strip is cut by the adhesive cutting mechanism 45, and at this time, a part of the adhesive tape strip on the second side f2 of the first adhesive tape sticking piece 3314 is the adhesive tape. Then, the rotating rod 442 drives the tape picking portion 443 to separate from the second side surface f2 of the first tape applying member 3314, so that the tape on the second side surface f2 of the first tape applying member 3314 is separated from the tape picking portion 443, i.e. a one-time tape supplying is realized.

It should be noted that, in this embodiment, the rotating rod 442 is rotated to drive the tape picking portion 443 disposed at the first end 4421 of the rotating rod 442 to descend or ascend, so that the tape picking portion 443 finishes a tape picking or releasing action, and a cylinder for driving the tape picking portion 443 to descend or ascend needs to be disposed at the tape picking portion 443, thereby simplifying a structure at the tape picking portion 443, on one hand, saving a space occupied by the tape picking portion 443, further reducing a space occupied by a tape supplying action, and facilitating reduction of difficulty in designing various mechanisms of the unwinding device 30 in terms of space arrangement; on the other hand, the weight of the tape picking portion 443 is reduced, which is beneficial to improving the stability of the tape picking portion 443 in completing the tape picking or releasing action.

In the embodiment, the supporting frame 41 of the glue supplying device 40 is fixedly connected to the base 11 of the carrying device 10 through the connecting seat 48, so that the glue supplying device 40 moves along with the base 11 of the carrying device 10 along the first direction X. The tape supplying device 40 can pass through the unwinding station in the process of moving along the first direction X along with the base 11, so that the tape supplying device 40 respectively supplies tapes to the first tape pasting part 3314 and the second tape pasting part 3324 of the unwinding device 30 at the unwinding station.

In particular, in the embodiment, the picking drive assembly further includes a picking drive member 444 disposed on the fourth movable base 441. The tape pick-up driving member 444 is coupled to the second end 4422 of the rotating rod 442 away from the tape pick-up portion 443 to drive the rotating rod 442 to rotate about the pivot axis, thereby lowering or raising the tape pick-up portion 443. In this way, the tape picking portion 443 is installed by the first end 4421 of the rotating rod 442, and the tape taking driving member 444 is connected by the second end 4422 of the rotating rod 442, so that the tape taking driving member 444 is spatially separated from the tape picking portion 443, and the purpose of reducing the space occupied by the tape picking portion 443 is achieved. Alternatively, the glue dispensing actuator 444 may employ an air cylinder.

Further, the pivot axis is located between the first end 4421 and the second end 4422 of the rotating rod 442, so that a "lever" structure is formed by the rotating rod 442, and the action of driving the tape picking portion 443 to descend or ascend is more labor-saving, and on one hand, the adhesive picking driving member 444 with a smaller specification can meet the requirement, thereby being beneficial to reducing the cost and saving the space; on the other hand, it is advantageous to increase the response speed of the driving tape pickup portion 443 to perform the lowering or raising operation. More specifically, a middle portion of the rotating rod 442 is mounted on the fourth moving seat 441 through a pivot shaft 445 such that the rotating rod 442 can rotate about the pivot shaft 445 with respect to the fourth mounting seat. The axis of the pivot shaft 445 is the pivot axis described above.

In the embodiment, the glue sucking platform 43 is located on one side of the supporting frame 41 in the first direction X, and the pickup driving assembly is located on the other side of the supporting frame 41 in the first direction X. So, will pick up drive assembly and inhale gluey platform 43 and divide and establish the relative both sides on first direction X at support frame 41 to avoid picking up drive assembly and cause the interference to the transport in sticky tape material area, and then improve the stability that supplies gluey operation process.

Specifically, in the embodiment, when the glue supplying device 40 moves to the unwinding station along the first direction X, the glue absorbing platform 43 and the first tape-on-tape 3314 of the unwinding device 30 are disposed along the second direction Y, so that the fourth moving seat 441 can drive the tape picking portion 443 to move between the glue absorbing platform 43 and the first tape-on-tape 3314 when moving along the second direction Y.

Further, the supporting frame 41 can also be controlled to drive the glue supplying device 40 to move along the second direction Y, so as to drive the glue sucking platform 43 to approach or depart from the first glue applying member 3314 of the unwinding device 30 along the second direction Y at the unwinding station. Therefore, after the supporting frame 41 drives the glue supplying device 40 to move to the unwinding station along the first direction X, the supporting frame 41 drives the glue supplying device 40 to move along the second direction Y near the first glue-pasting part 3314 of the unwinding device 30, so that the glue absorbing platform 43 is further near the first glue-pasting part 3314 of the unwinding device 30, and the glue is supplied to the first glue-pasting part 3314 of the unwinding device 30. After the glue supply is completed, the supporting frame 41 drives the glue supply device 40 to move along the first gluing part 3314 far away from the unwinding device 30 in the second direction Y, so as to drive the glue sucking platform 43 to move away from the first gluing part 3314 far away from the unwinding device 30, thereby preventing the unwinding device 30 from interfering with the movement of the glue supply device 40 in the process that the supporting frame 41 drives the glue supply device 40 to move along the first direction X. Alternatively, the supporting frame 41 is mounted on the connecting base 48 through a sliding rail and a slider to guide the movement of the supporting frame 41 relative to the connecting base 48 in the second direction Y. A linear driving member such as an electric cylinder or an air cylinder may be used to drive the supporting frame 41 to move along the second direction Y relative to the connecting base 48.

In the embodiment, the tape picking portion 443 is a glue pulling roller having a rotation state rotatable about its axis and a rotation stop state unrotatable about its axis. When the fourth moving seat 441 drives the glue pulling roller to move to the glue sucking platform 43, the glue pulling roller is switched to a rotating state, and the fourth moving seat 441 can drive the glue pulling roller to move upstream by a preset distance along the glue sucking platform 43 so as to wind the end part of the adhesive tape strip on the glue sucking platform 43 onto the glue pulling roller.

When the fourth moving base 441 drives the glue pulling roller to move from the glue sucking platform 43 to the first glue sticking piece 3314 of the unreeling device 30, the glue pulling roller is switched to a rotation stopping state, so that the tape wound on the glue pulling roller is prevented from falling off in the glue pulling process.

When the fourth moving base 441 drives the glue pulling roller to move to the second side surface f2 of the first rubberizing part 3314, the glue pulling roller is switched to a rotating state, and the fourth moving base 441 can drive the glue pulling roller to move downstream by a preset distance along the second side surface f2 of the first rubberizing part 3314, so as to flatten the tape strip wound on the glue pulling roller onto the second side surface f2 of the first rubberizing part 3314.

Therefore, when the rubber pulling roller picks up the adhesive tape strip or releases the adhesive tape strip, the rubber pulling roller is controlled to be in a rotating state so as to facilitate winding or flattening of the adhesive tape strip; when the rubber belt material belt is pulled by the rubber pulling roller, the rubber pulling roller is controlled to be in a rotation stopping state, and the rubber belt material belt is prevented from falling off from the rubber pulling roller.

In one embodiment, the glue supplying device 40 further includes a rotation stopping mechanism, which includes a rotation stopping driving element 461 and a rotation stopping element 462. The rotation stopping driving member 461 is mounted on the fourth moving seat 441, and is in driving connection with the rotation stopping member 462 so as to drive the rotation stopping member 462 to be engaged with or separated from the glue pulling roller in a rotation stopping manner. Thus, when the glue roller needs to rotate, the rotation stopping driving member 461 drives the rotation stopping member 462 to separate from the glue roller, so that the rotation stopping member 462 cannot prevent the glue roller from rotating. When the glue drawing roller does not need to rotate, the rotation stopping driving piece 461 drives the rotation stopping piece 462 to be matched with the glue drawing roller in a rotation stopping manner, so that the rotation stopping piece 462 can prevent the glue drawing roller from rotating. Alternatively, the rotation stop driving member 461 may employ an air cylinder.

The operation of the glue supplying device 40 for supplying glue to the second side f2 of the first glue applying part 3314 of the unwinding device 30 is described as follows: first, the glue supply device 40 moves to the unwinding station along the first direction X until the glue sucking platform 43 is aligned with the first glue applying component 3314 along the second direction Y. The supporting frame 41 moves along the second direction Y to drive the glue-sucking platform 43 to approach the first glue-sticking component 3314. Then, the fourth moving seat 441 moves along the second direction Y to drive the glue spreading roller to move to the glue sucking platform 43. Then, the rotating rod 442 drives the glue pulling roller to descend to abut against the glue sucking platform 43. Then, the fourth moving seat 441 moves along the second direction Y, so as to drive the glue drawing roller to roll a distance upstream along the glue sucking platform 43, so as to wind the adhesive tape strip on the glue sucking platform 43 on the glue drawing roller. Then, the rotating rod 442 drives the glue pulling roller to lift up, so that the glue pulling roller drives the tape strip to separate from the glue sucking platform 43.

Then, the rotation stopping member 462 is controlled to be matched with the glue pulling roller for rotation stopping, and the fourth moving seat 441 moves along the second direction Y until the glue pulling roller is driven to move to the second side surface f2 of the first gluing member 3314. Then, the rotation stopping member 462 is controlled to separate from the glue pulling roller, and the rotating rod 442 drives the glue pulling roller to descend to abut against the second side surface f2 of the first tape sticking member 3314. Then, the fourth moving seat 441 moves along the second direction Y to drive the glue pulling roller to roll downstream for a certain distance along the second side surface f2 of the first gluing part 3314, and the second side surface f2 of the first gluing part 3314 adsorbs the adhesive tape strip on the glue pulling roller while rolling, so that the adhesive tape strip wound on the glue pulling roller is gradually flattened on the second side surface f2. After the tape strip on the glue pulling roll is completely flattened on the second side surface f2, the rotating rod 442 drives the glue pulling roll to be lifted up, so that the glue pulling roll is separated from the second side surface f2 of the first rubberizing part 3314, and the tape is adsorbed on the second side surface f2, namely, the glue supply to the second side surface f2 of the first rubberizing part 3314 is completed.

It should be noted that the glue supplying process of the glue supplying device 40 to the fourth side g2 of the second glue supplying member is similar to the above process, and therefore, the description is omitted here.

Referring to fig. 12 to 16, in an embodiment of the present invention, the picking apparatus 20 includes a picking mechanism 21, and the picking mechanism 21 includes a sixth movable base 211, and a blowing assembly 212 and a clamping assembly 213 both disposed on the sixth movable base 211. The sixth movable base 211 is movable in the third direction Z to move the blowing assembly 212 and the clamping assembly 213 between the standby roll a on the handling device 10 and the pulling position. Optionally, the third direction Z is perpendicular to the first direction X and the second direction Y.

When the sixth moving seat 211 drives the blowing assembly 212 and the clamping assembly 213 to move to the stock roll a on the carrying device 10 along the third direction Z, the blowing assembly 212 can blow up the starting end a of the stock roll a, so that the clamping assembly 213 can clamp the blown starting end a of the stock roll a. When the sixth moving seat 211 drives the blowing assembly 212 and the clamping assembly 213 to move to the drawing position along the third direction Z, the clamping assembly 213 draws the spare tape on the spare material roll a, so that the carrying device 10 can be sucked and fixed by the cutting position between the spare material roll a and the drawing position and cut the spare tape, and the end of the spare tape and the end of the cut waste material segment are sucked and fixed by the first sucking surface b of the sucking seat 141 of the carrying device 10.

In this way, when the handling device 10 moves to the picking station and the end of the stock strip of the stock roll a needs to be processed, first, the sixth moving seat 211 moves along the third direction Z, and drives the blowing assembly 212 and the clamping assembly 213 to move towards the stock roll a on the loading shaft 12 until reaching the stock roll a. Then, the blowing assembly 212 blows air toward the tape starting end a on the standby roll a to blow up the tape starting end a. Then, the start end a of the blown tape is held by the holding member 213. After the starting end a of the material tape is clamped, the sixth moving seat 211 moves along the third direction Z to drive the air blowing assembly 212 and the clamping assembly 213 to move away from the material roll a, so as to pull out the material tape on the material roll a until the air blowing assembly 212 and the clamping assembly 213 reach the pulling position. Then, the conveying device 10 cuts the backup tape from the cutting position between the backup roll a and the drawing position by the first cutter 133, and fixes the end of the backup tape and the end of the cut scrap piece by suction by the first suction surface b of the suction base 141.

It should be noted that, in order to ensure that the air blowing assembly 212 can accurately blow the starting end a of the material tape, before the air blowing assembly 212 blows air, the carrying device 10 needs to drive the stock roll a thereon to rotate until the starting end a of the material tape is driven to be located on the side of the stock roll a facing the air blowing assembly 212 and the clamping assembly 213. Alternatively, a position sensor may be used to detect the position of the label on the starting end a of the strip of material to determine whether the starting end a of the strip of material reaches the side of the reserve roll a facing the blowing assembly 212 and the gripping assembly 213.

Above-mentioned pickup apparatus 20, utilize the subassembly 212 of blowing to blow up the material area initiating terminal a of reserve material roll A, it gets this material area initiating terminal a and pulls out the reserve material area to recycle centre gripping subassembly 213 clamp, make handling device 10 after the waste material section excision of reserve material area, the tip of reserve material area and the tip of waste material section are all adsorbed and are fixed on the first adsorption plane b of adsorption seat 141, and then make the tip of reserve material area lifted and keep being convenient for follow-up and the state of the cutting off end area in work material area, need not the manual work and handle the tip of reserve material area of reserve material roll A, the degree of automation of the equipment of changing a roll has been improved, the labor cost is reduced, the stability of production efficiency and production quality has been improved.

It should be noted that, in the prior art, the starting end a of the material tape on the standby material roll a is often sucked by using a vacuum adsorption method, however, the vacuum adsorption method has the problems of poor adsorption stability, large vacuum maintaining energy consumption and the like. Compared with this, in this embodiment, the blowing assembly 212 is firstly used to blow up the starting end a of the material tape on the standby material roll a, and then the clamping assembly 213 is used to clamp the starting end a of the material tape and pull out the standby material tape, so that the carrying device 10 can lift up the standby material tape and fix the end of the standby material tape, thereby avoiding the need of maintaining vacuum for a long time, reducing energy consumption, and fixing the starting end a of the material tape in a clamping manner is stable and reliable.

It should be noted that the above-mentioned drawing position refers to a position reached by the holding assembly 213 after holding the starting end a of the tape at the stock roll a and moving away from the stock roll a for a distance in the third direction Z. The distance between the drawing position and the supply roll a is not limited, as long as it is ensured that the waste section on the supply roll a is completely drawn out when the holding assembly 213 is moved to the drawing position, and the end of the supply roll a can be held by the handling device 10 after the waste section has been cut off.

In particular embodiments, the picking mechanism 21 further includes a detection assembly 2121 mounted on the sixth movable base 211, and the blowing assembly 212 is mounted on the detection assembly 2121. The detecting unit 2121 is configured to detect whether the blowing assembly 212 abuts against the stock roll a on the carrying device 10 during the process of the sixth moving seat 211 moving the blowing assembly 212 and the clamping assembly 213 from the pulling position toward the stock roll a on the carrying device 10. Further, when the detecting unit 2121 detects that the blowing unit 212 abuts against the stock roll a, the sixth moving seat 211 is controlled to stop moving, so as to avoid crushing the stock roll a. At this time, the blowing assembly 212 can be used to blow up the starting end a of the tape on the stock roll a, and the clamping assembly 213 is used to clamp the blown starting end a of the tape.

Optionally, the detecting assembly 2121 includes an air cylinder and a magnetic switch disposed on the air cylinder, and the air blowing assembly 212 is mounted at a driving end of the air cylinder. The driving end of the air cylinder is in an extending state during the process that the sixth movable seat 211 drives the air blowing assembly 212 to move from the pulling position to the standby material roll a on the carrying device 10. When the air blowing assembly 212 abuts the backup roll a, the driving end of the air cylinder is compressed. When the magnetic switch detects that the driving end of the air cylinder is pressed to contract, the sixth moving seat 211 is controlled to stop moving through a control device such as an industrial personal computer, and the standby material roll A is prevented from being damaged by pressure.

Further, the air blowing device includes an air blowing piece 2122 and a pressing wheel 2123. The blowing member 2122 is mounted at the driving end of the cylinder of the detecting unit 2121, and the pressing wheel 2123 is rotatably connected to the blowing member 2122 about its axis. While the sixth moving base 211 drives the blowing assembly 212 to move from the drawing position toward the stock roll a on the carrying device 10, the pressing wheel 2123 can be driven to abut against the stock roll a on the loading shaft 12. When the detecting unit 2121 detects that the pressing roller 2123 abuts on the backup roll a, the sixth moving base 211 stops moving. Therefore, the pressing wheel 2123 is abutted against the standby material roll a, so that the situation that the blowing piece 2122 is directly contacted with the standby material roll a to damage the standby material roll a is favorably avoided.

It should be noted that, the arrangement of the detecting component 2121 ensures that, when the end of the standby material tape of the standby material roll a is processed each time, after the pressing wheel 2123 abuts against the standby material roll a, the air blowing component 2122 blows air to the starting end a of the material tape on the standby material roll a, so as to ensure that the starting end a of the material tape can be blown up accurately, which is beneficial to adapting to the standby material rolls a with different roll diameters, and improves the compatibility of the device.

Further, the number of the pressing wheels 2123 is two, and the two pressing wheels 2123 are respectively located at two ends of the air blowing element 2122 in a first preset direction, and the first preset direction is parallel to the axial direction of the spare material roll a. Thus, the two pressing wheels 2123 abut against the material roll a, so that the position between the material roll a and the air blowing piece 2122 is more stable and reliable, and the air blowing piece 2122 can accurately blow up the starting end a of the material belt onto the clamping assembly 213. It will be understood that the axis of the reserve roll a is parallel to the axis of the loading shaft 12. In the embodiment shown in fig. 15, the first predetermined direction is a direction perpendicular to the plane of the paper.

Further, the air blowing member 2122 has an air blowing slit for blowing air to the tape starting end a, and the air blowing slit extends lengthwise along the first predetermined direction, which is beneficial to ensure that the tape starting end a on the standby material roll a is blown up.

In one embodiment, the clamping assembly 213 includes a clamping driving member 2131, and a first clamping block 2132 and a second clamping block 2133 disposed at a driving end of the clamping driving member 2131. A clamping space for the start end a of the blown tape to enter is formed between the first clamping block 2132 and the second clamping block 2133. The clamping driving member 2131 is used for driving the first clamping block 2132 and the second clamping block 2133 to move close to or away from each other, so as to clamp or release the tape starting end a entering the clamping space. In this way, the blowing member 2122 blows the starting end a of the tape on the standby material roll a up to the clamping space, so that the clamping driving member 2131 can clamp the blown starting end a of the tape when driving the first clamping block 2132 and the second clamping block 2133 to approach each other. Alternatively, the clamp driver 2131 may employ a jaw cylinder.

Alternatively, the first and second clamp blocks 2132 and 2133 are arranged in a second predetermined direction perpendicular to the axial direction of the stock roll a on the carrying device 10. Thus, when the starting end a of the material tape blown by the blowing member 2122 enters the clamping space between the first clamping block 2132 and the second clamping block 2133, the first clamping block 2132 and the second clamping block 2133 are respectively located on two sides of the starting end a of the material tape in the thickness direction, so that the first clamping block 2132 and the second clamping block 2133 clamp the starting end a of the material tape in the thickness direction of the starting end a of the material tape, and the starting end a of the material tape is stably and reliably clamped. In the embodiment shown in fig. 15, the second predetermined direction is perpendicular to the left-right direction.

In particular embodiments, the picking mechanism 21 further comprises a picking drive 214. The picking driving member 214 is drivingly connected to the sixth moving seat 211, and is configured to drive the sixth moving seat 211 to move along the third direction Z, so as to drive the blowing assembly 212 and the holding assembly 213 to move to the spare tape a or the pulling position. Alternatively, the pickup drive 214 may employ an electric cylinder.

It should be noted that the detecting element 2121 is communicatively connected to the picking driving element 214 through a control device such as an industrial personal computer, so that the control device can control the picking driving element 214 to stop driving the sixth moving seat 211 to move continuously toward the standby reel a according to the detection result of the detecting element 2121.

In some embodiments, the holding assembly 213 holds the starting end a of the tape on the backup roll a and moves to the pulling position by the sixth moving seat 211, so as to pull out the backup tape on the backup roll a, and the backup tape is routed through the cutting position and the winding position between the backup roll a and the pulling position. The cutting position is located between the reserve roll a and the take-up position. The spare material belt between the cutting position and the traction position is a waste material section. The first cutter 133 of the handling device 10 cuts the spare tape from the cutting position, i.e. cuts off the waste section. After the first cutter 133 cuts the waste material segment, the end of the waste material segment is sucked and fixed by the first suction surface b of the suction base 141, and the tape start end a of the waste material segment is held and fixed by the holding member 213.

As shown in fig. 17 to 18, the picking device 20 further includes a waste collecting mechanism 22, and the waste collecting mechanism 22 is used for collecting the waste material segment of the spare material tape passing through the collecting position, so that the holding component 213 can pick up the material tape start end a of the next spare material roll a again.

Specifically, the waste collecting mechanism 22 includes a fifth movable base 221 and a collecting shaft 222. One end of the material receiving shaft 222 is disposed on the fifth movable base 221, and the material receiving shaft 222 is rotatable around its axis relative to the fifth movable base 221. The material receiving shaft 222 has a fork groove k1 extending along the axial direction, and the fork groove k1 is used for the waste material section to pass through, so that the waste material section can be wound on the material receiving shaft 222 when the material receiving shaft 222 rotates around the axis of the material receiving shaft.

Further, the material forking groove k1 penetrates through one end of the material receiving shaft 222 far away from the fifth movable seat 221, that is, one end of the material receiving shaft 222 far away from the fifth movable seat 221 is an open end k2, so that the waste material segment can enter the material forking groove k1 through the open end k 2. The fifth moving base 221 is controllably moved along a third predetermined direction (i.e., left-right direction in fig. 18) to drive the material receiving shaft 222 to or away from the winding position. When the fifth movable seat 221 drives the material receiving shaft 222 to reach the winding position, the waste material segment of the standby material tape enters the material forking slot k1 through the opening end k 2. Optionally, the axial direction of the receiving shaft 222 is parallel to the axial direction of the loading shaft 12, and is also parallel to the third predetermined direction, so as to facilitate the entry of the waste segment of the spare tape into the fork k 1.

Thus, when the clamping assembly 213 is moved from the material roll a to the drawing position and draws out the waste section of the material strip, the waste section needs to be rolled: first, the fifth moving seat 221 moves to the winding position along the third preset direction, so that the waste material segment passing through the winding position enters the fork k1 from the open end k2 of the material receiving shaft 222. Then, the material area initiating terminal a of waste material section is loosened to centre gripping subassembly 213 to it is rotatory to control receipts material axle 222, makes waste material section by the rolling gradually on receiving material axle 222, realizes the automatic collection to waste material section promptly, has improved the degree of automation of the equipment of changing a roll, has improved production efficiency and production quality's stability, has reduced the cost of labor.

In specific embodiments, the material collecting shaft 222 comprises a main body section 2220 and a winding section 2223 arranged along the self axial direction. One end of the main body section 2220 is disposed on the fifth movable base 221 so that the material receiving shaft 222 can rotate around its axis with respect to the fifth movable base 221. The winding section 2223 includes a first half shaft 2225 and a second half shaft 2226. The first half shaft 2225 and the second half shaft 2226 are both connected to the other end of the main body section 2220, and are arranged at intervals along the radial direction of the main body section 2220, so that the fork groove k1 is formed between the first half shaft 2225 and the second half shaft 2226, and the open end k2 is formed at the end of the first half shaft 2225 and the end of the second half shaft 2226 away from the main body section 2220, so that in the process that the fifth moving seat 221 drives the material receiving shaft 222 to move to the winding position along the third preset direction, the waste material sections passing through the winding position gradually enter the fork groove k1 between the first half shaft 2225 and the second half shaft 2226, and the waste material sections can be wound up when the material receiving shaft 222 rotates.

Alternatively, a side surface of the first half shaft 2225 facing away from the second half shaft 2226 is a first arc surface, and a side surface of the second half shaft 2226 facing away from the first half shaft 2225 is a second arc surface, so that the first arc surface of the first half shaft 2225 and the first arc surface of the second half shaft 2226 are joined to form a substantially cylindrical outer contour. Specifically, the first cambered surface and the second cambered surface are both arc surfaces and are positioned on the same cylindrical surface, so that the first cambered surface and the second cambered surface are spliced to form a cylindrical outer contour.

Further, the waste collecting mechanism 22 further includes a rotary driving member 226, and the rotary driving member 226 is mounted on the fifth movable base 221 and is drivingly connected to the material receiving shaft 222 to drive the material receiving shaft 222 to rotate.

Further, the waste collecting mechanism 22 further includes a translational driving member 223, and the translational driving member 223 is in driving connection with the fifth movable seat 221 to drive the fifth driving seat to move along the third preset direction. Alternatively, the translation drive 223 may employ an electric cylinder.

In particular embodiments, the waste collection mechanism 22 further includes a kick-out assembly disposed corresponding to the winding position. The material stirring component comprises a material stirring driving piece 2271 and a material stirring piece 2272, and the material stirring piece 2272 is installed at the driving end of the material stirring driving piece 2271. When receiving the material axle 222 and being located the rolling position, dial material driving piece 2271 and can drive and dial material piece 2272 and insert by the one end that fork silo k1 is close to fifth removal seat 221 to in-process that fifth removal seat 221 drove and receive material axle 222 and leave the rolling position, dial material piece 2272 and will convolute the waste material section on receiving the material axle 222 and dial away, be about to the waste material section from receiving the material axle 222 and dial away, so that receive the material axle 222 and receive the waste material section once more. Thus, when the material receiving shaft 222 finishes the winding of the waste material segment at the winding position, firstly, the material poking driving member 2271 drives the material poking member 2272 to be inserted from the end of the fork chute k1 close to the fifth movable seat 221. Then, the fifth moving seat 221 drives the material receiving shaft 222 to leave the winding position, and the waste material section on the material receiving shaft 222 is blocked by the material poking member 2272 and cannot move along with the material receiving shaft 222, so that the waste material section is poked away from the material receiving shaft 222 by the material poking member 2272. Alternatively, the kick-out drive 2271 may be a pneumatic cylinder.

Further, the waste collection mechanism 22 further includes a waste discharge assembly disposed corresponding to the winding position. The waste discharge assembly includes a waste discharge tube 228, the inlet of which is located below the kick-out 2272 to receive the waste section that is kicked off the take-up shaft 222 by the kick-out 2272. So, when receiving material axle 222 and accomplishing the rolling of waste material section in the rolling position, dial material piece 2272 and insert the back in fork silo k1, fifth removal seat 221 drives and receives material axle 222 and leaves the rolling position for dial material piece 2272 will receive the waste material section on the material axle 222 and dial away.

Further, the waste assembly also includes a waste magazine 2281, the waste magazine 2281 being disposed at the discharge outlet of the waste pipe 228 to receive the waste segment discharged from the discharge outlet of the waste pipe 228.

In an embodiment, the waste collecting mechanism 22 further includes a winding diameter detecting member 224 disposed on the fifth movable seat 221. The roll diameter detecting member 224 is used for detecting the roll diameter of the waste material segment wound on the material receiving shaft 222. Thus, when the winding diameter detecting component 224 detects that the winding diameter on the material receiving shaft 222 reaches the preset value or no longer increases, it indicates that the winding of the waste material segment is completed, and at this time, the material receiving shaft 222 can be controlled to stop rotating.

In an embodiment, the waste collecting mechanism 22 further includes a pressing component 225, and the pressing component 225 includes a support 2251 and a pressing roller. The support is connected to the fifth movable seat 221, and the pressing roller is disposed on the support and used for abutting against the waste material segment wound on the material receiving shaft 222. Thus, in the process of winding the waste material section by the material receiving shaft 222, the pressing roller compacts the waste material section on the material receiving shaft 222, and the waste material section wound on the material receiving shaft 222 is prevented from being loose.

Further, the pressing component 225 further includes a swinging component and a third elastic component. One end of the swinging piece is rotatably connected to the bracket, and the pressing roller is arranged at the other end of the swinging piece. The third elastic member is connected to the swinging member and the bracket, and is used for providing a pre-tightening force for driving the pressing roller to elastically press the material receiving shaft 222 by the swinging member. So, under the effect of third elastic component, the swing piece drives to support the compression roller and leans on all the time to lean on receiving axle 222 (pressing pipe and receiving axle 222 elasticity butt promptly) for the waste material section is supported the compression roller and is compacted on receiving axle 222 when receiving axle 222 and carrying out the rolling to the waste material section, avoids receiving the waste material section on the axle 222 loose. Optionally, the winding diameter detecting member 224 is also mounted on the bracket, so that the winding diameter detecting member 224 and the pressing roller share the same bracket for mounting, which is beneficial to simplifying the structure.

The third elastic element is a torsion spring, the torsion spring is sleeved on the rotating shaft, one torsion arm of the torsion spring is abutted to the support, the other torsion arm of the torsion spring is abutted to the swinging element, and therefore the swinging element drives the abutting roller to always keep abutting against the material receiving shaft 222 under the action of the torsion spring.

With continued reference to fig. 17 to 18, in an embodiment of the invention, the reel changer further comprises a stock preparation device for providing a stock roll a to the loading spindle 12 of the handling device 10 moving to the pick-up station.

The charging pipe is loaded with a plurality of stock rolls A. The second clamping assembly 55 is movable relative to the fixed seat 51 in the axial direction of the stock preparation shaft 52 to push the stock roll a on the charging tube onto the charging shaft 12 of the handling device 10 from the feeding end 522.

In actual use, the loading shaft 12 of the handling device 10 is axially butted against the loading end 522 of the stock shaft 52 when the handling device 10 moves to reach the picking station. The second clamping assembly 55 is moved a predetermined distance toward the feeding end 522 along the axial direction of the stock axle 52, so that the second clamping assembly 55 pushes each of the stock rolls a on the stock axle 52 toward the feeding end 522 until the foremost one of the stock rolls a is moved from the feeding end 522 onto the loading axle 12 of the transfer device 10. And, during the process of pushing the stock rolls a by the second clamping assembly 55, the first clamping assembly 54 always clamps the charging tube, so that the charging tube remains stationary with respect to the stock spindle 52, while each stock roll a moves along the charging tube towards the charging spindle 12, pushed by the second clamping assembly 55.

Therefore, on one hand, the standby material roll A is automatically pushed to the loading shaft 12 of the carrying device 10, the manual loading to the loading shaft 12 is avoided, the labor cost is reduced, the automation degree of roll changing equipment is improved, and the production efficiency is improved; on the other hand, when the material needs to be fed to the material preparing shaft 52, the material feeding pipes can be used for feeding a plurality of material rolls A to the material preparing shaft 52 at one time, and are clamped and fixed through the first clamping assemblies 54, so that the material feeding pipes are prevented from moving away from the shaft relatively when the material is fed to the material feeding shaft 12, the material rolls A do not need to be fed to the material preparing shaft 52 one by one, and the feeding efficiency of the material to the material preparing shaft 52 is greatly improved.

In one embodiment, the material preparing apparatus further comprises a feeding mechanism having a feeding shaft. The feeding shaft is used for sleeving a feeding pipe loaded with a plurality of standby material rolls A. When the feeding mechanism moves to the position where the feeding shaft is in axial butt joint with the feeding end 522 of the material preparing shaft 52, the second clamping assembly 55 moves to the position of the feeding shaft along the axial direction of the material preparing shaft 52 and clamps the feeding pipe on the feeding shaft, and then moves back along the axial direction of the material preparing shaft 52 until the feeding pipe on the feeding shaft and each standby material roll a on the feeding pipe are driven to move onto the material preparing shaft 52 together and are separated from the feeding shaft, so that the transfer of the feeding pipe and each standby material roll a on the feeding pipe from the feeding shaft to the material preparing shaft 52 is realized. Alternatively, the feed mechanism may be a transfer cart. The charging pipe can be a steel pipe.

Therefore, by utilizing the matching of the feeding mechanism and the material preparing mechanism 50, the material transferring pipe loaded with a plurality of standby material rolls A is transferred onto the material preparing shaft 52 at one time, on one hand, the automation degree of the roll changing equipment is further improved, and the labor cost is reduced; on the other hand, a plurality of standby material rolls A are fed onto the material preparing shaft 52 at the same time, and the feeding efficiency is greatly improved.

The second clamping position is formed between the third clamping end and the fourth clamping end. The second clamp driver 554 is drivingly connected to the third and fourth drive ends to drive the third and fourth drive ends toward and away from each other.

Thus, when the clamping of the charging tube is required (i.e. when the charging tube on the charging shaft is required to be loaded onto the preparation shaft 52), the second clamping driving member 554 drives the third driving end and the fourth driving end to move away from each other, so as to drive the third clamping member 552 and the fourth clamping member 553 to rotate, so as to make the third clamping end and the fourth clamping end approach each other until the charging tube is clamped.

When it is desired to unwind the charging tube (i.e., to push a supply roll a from the charging tube on the supply spool 52 onto the charging spool 12), the second clamp actuator 554 drives the third and fourth actuating ends toward each other, thereby rotating the third and

fourth clamps

552 and 553, and thus moving the third and fourth clamping ends away from each other to unwind the charging tube. At this point, the first clamping assembly 54 clamps the charging tube on the supply spool 52, and the second clamping assembly 55 unclamps the charging tube and pushes the stock roll a on the charging tube to move until the stock roll a is transferred to the supply spool 12.

Further, the second clamping assembly 55 further includes a second transmission structure, and the third transmission end and the fourth transmission end are in transmission connection with the second clamping driving member 554 through the second transmission structure. The second clamping driver 554 is configured to output a linear motion to a second transmission structure, which is configured to convert the linear motion into a rotational motion of the third and

fourth clamping members

552 and 553, thereby moving the third and fourth clamping ends toward and away from each other.
