Referring to fig. 1 and 2, an embodiment of the present invention provides a roll changing device, which includes an unreeling assembly 10 and a roll changing assembly disposed downstream of the unreeling assembly 10. The unreeling assembly 10 comprises a first unreeling mechanism 11 for unreeling the first material strip a, and a second unreeling mechanism 12 for unreeling the second material strip. The first material belt a unreeled and output by the first unreeled mechanism 11 or the second material belt unreeled and output by the second unreeled and output mechanism 12 can pass through the reel changing assembly and be conveyed downstream. The reel changing assembly is used for realizing the switching between the first material belt a and the second material belt, namely when the first material belt a on the first unreeling mechanism 11 is unreeled, the reel changing assembly switches the second material belt unreeled and output by the second unreeled mechanism 12 to be conveyed to the downstream, and when the second material belt unreeled by the second unreeled mechanism 12 is completed, the reel changing assembly switches the first material belt a unreeled and output by the first unreeled mechanism 11 to be conveyed to the downstream.
The roll changing assembly comprises a mounting seat 21, a first adsorption mechanism 22, a second adsorption mechanism 23 and a cutting mechanism 24 which are arranged on the mounting seat 21. The first adsorption mechanism 22 includes a first adsorption seat 221, and the second adsorption mechanism 23 includes a second adsorption seat 231. The first adsorption seat 221 and the second adsorption seat 231 are arranged along the first direction, so that the first material belt a unreeled and output by the first unreeled mechanism 11 or the second material belt unreeled and output by the second unreeled mechanism 12 passes through between the first adsorption seat 221 and the second adsorption seat 231 and is conveyed downstream. The first suction seat 221 and the second suction seat 231 are configured such that at least one thereof can be moved closer to or away from each other with respect to the other in the first direction, so that the first material belt a or the second material belt passing between the first suction seat 221 and the second suction seat 231 can be gripped when the first suction seat 221 and the second suction seat 231 are moved closer to each other.
The side of the first adsorption seat 221 facing the second adsorption seat 231 has a first adsorption area 2211 and a second adsorption area 2212 arranged along a second direction perpendicular to the first direction. The first adsorption area 2211 is used for adsorbing the first material belt a, and the second adsorption area 2212 is used for adsorbing the second material belt. The first adsorption seat 221 is further configured to be movable in a second direction perpendicular to the first direction, and the first adsorption region 2211 and the second adsorption region 2212 may be alternately aligned with the second adsorption seat 231 in the first direction during the movement of the first adsorption seat 221 in the second direction. When the first suction area 2211 is aligned with the second suction seat 231 in the first direction, the first suction seat 221 and the second suction seat 231 are close to each other in the first direction to clamp the first material tape a passing between the first suction area 2211 and the second suction seat 231; when the second adsorption area 2212 is aligned with the second adsorption seat 231 in the first direction, the first adsorption seat 221 and the second adsorption seat 231 approach each other in the first direction to clamp the second material belt passing between the second adsorption area 2212 and the second adsorption seat 231.
The cutting mechanism 24 is disposed upstream of the first adsorption seat 221, and is used for cutting off the first material belt a between the second adsorption seat 231 and the first adsorption area 2211 of the first adsorption seat 221, or the second material belt between the second adsorption seat 231 and the second adsorption area 2212 of the first adsorption seat 221. Alternatively, the first and second strips of material may be adhesive tape.
In the above-mentioned reel changer, taking the first material strip a unreeled and output by the first unreeled mechanism 11 as a working material strip and the second material strip unreeled and output by the second unreeled mechanism 12 as a spare material strip, the second adsorption seat 231 is aligned with the first adsorption area 2211 of the first adsorption seat 221 in the first direction, the first material strip a unreeled and output by the first unreeled mechanism 11 passes through between the second adsorption seat 231 and the first adsorption area 2211 of the first adsorption seat 221 and is conveyed downstream, and the beginning end of the second material strip unreeled and output by the second unreeled mechanism 12 is adsorbed and fixed on the second adsorption area 2212 of the first adsorption seat 221. When the first unreeling mechanism 11 runs out and needs to change the reel, first, the first adsorbing seat 221 and the second adsorbing seat 231 are close to each other to clamp the first tape a, the cutting mechanism 24 cuts the first tape a, and the second adsorbing seat 231 adsorbs the cut first tape a. Then, the first suction pad 221 and the second suction pad 231 are separated from each other, and the first suction pad 221 is moved in the second direction until the second suction area 2212 is aligned with the second suction pad 231 in the first direction, and the first suction pad 221 and the second suction pad 231 are close to each other to adhere the cut first tape a sucked by the second suction pad 231 to the start end of the second tape sucked by the second suction area 2212. Finally, the second adsorption area 2212 of the first adsorption seat 221 releases the adsorption of the second material belt, the second adsorption seat 231 releases the adsorption of the cut first material belt a, and the first adsorption seat 221 and the second adsorption seat 231 are far away from each other, so that the second material belt is conveyed downstream along with the cut first material belt a passing through between the first adsorption seat 221 and the second adsorption seat 231, namely, the reel change is realized.
Therefore, the roll changing device can realize automatic switching (namely automatic roll changing) of the first material strip a and the second material strip, compared with a manual roll changing mode adopted in the prior art, the roll changing device greatly shortens the downtime, improves the production efficiency, does not need personnel on duty, reduces personnel configuration, and further reduces the labor cost.
The first material belt a and the second material belt may be adhesive tapes, so that the leading end of the first material belt a may be bonded to the cut end of the second material belt or the leading end of the second material belt may be bonded to the cut end of the first material belt a during the reel change. Of course, in other embodiments, the first and second webs a and b may not be adhesive tapes. At this time, the beginning end of the first material belt a on the material roll is stuck with double-sided adhesive tape, so that the beginning end of the first material belt a is adhered with the cutting end of the second material belt in the process of changing the roll. The leading end of the second material belt on the material roll is stuck with double-sided adhesive tape so as to bond the leading end of the second material belt with the cutting end of the first material belt a in the process of changing the roll.
It should be noted that, in the embodiment shown in fig. 1, the first direction is an up-down direction, and the second direction is a direction perpendicular to the paper surface.
In the embodiment of the present invention, the first adsorption seat 221 includes a first position and a second position during moving along the second direction.
When the first suction holder 221 is located at the first position, the second suction holder 231 is aligned with the first suction area 2211 in the first direction, and the cutting mechanism 24 is configured to cut the first material belt a clamped by the first suction holder 221 and the second suction holder 231 approaching each other along the first direction, and the second suction holder 231 can suction the cut first material belt a. In this way, when the roll on the first unreeling mechanism 11 runs out and needs to be replaced, the first adsorption seat 221 and the second adsorption seat 231 are first moved close to each other, so as to clamp the first tape a between the first adsorption area 2211 of the first adsorption seat 221 and the second adsorption seat 231, and the cutting mechanism cuts the first tape a, and the second adsorption seat 231 adsorbs the cut first tape a. Then, the first adsorption seat 221 and the second adsorption seat 231 are separated from each other, and the first adsorption seat 221 is moved in the second direction until the second adsorption area 2212 is aligned with the second adsorption seat 231 in the first direction. Then, the second suction holder 231 and the first suction holder 221 are brought close to each other to adhere the cut first tape a sucked by the second suction holder 231 to the leading end of the second tape sucked by the second suction area 2212. Finally, the second adsorption area 2212 of the first adsorption seat 221 releases the adsorption of the second material belt, the second adsorption seat 231 releases the adsorption of the cut first material belt a, and the first adsorption seat 221 and the second adsorption seat 231 are far away from each other, so that the second material belt can pass between the first adsorption seat 221 and the second adsorption seat 231 following the cut first material belt a, and then is conveyed downstream. It should be understood that the adsorption of the first material strip a by the second adsorption seat 231 may be performed before the cutting mechanism 24 cuts the first material strip a, or after the cutting mechanism 24 cuts the first material strip a, which is not limited herein.
When the first suction seat 221 is located at the second position, the second suction seat 231 is aligned with the second suction area 2212 in the first direction, the cutting mechanism 24 is used for cutting off the second material belt clamped by the first suction seat 221 and the second suction seat 231 approaching to each other along the first direction, and the second suction seat 231 can suck the cut second material belt. In this way, when the roll on the second unreeling mechanism 12 is exhausted and the roll replacement is required, first, the first adsorption seat 221 and the second adsorption seat 231 are close to each other, so as to clamp the second material strip between the second adsorption area 2212 of the first adsorption seat 221 and the second adsorption seat 231, and the cutting mechanism cuts the second material strip, and the second adsorption seat 231 adsorbs the cut second material strip. Then, the first adsorption seat 221 and the second adsorption seat 231 are separated from each other, and the first adsorption seat 221 is moved in the second direction until the first adsorption area 2211 is aligned with the second adsorption seat 231 in the first direction. Then, the second suction holder 231 and the first suction holder 221 are brought close to each other to adhere the cut second tape sucked by the second suction holder 231 to the leading end of the first tape a sucked by the first suction area 2211. Finally, the first adsorption area 2211 of the first adsorption seat 221 releases the adsorption of the first material belt a, the second adsorption seat 231 releases the adsorption of the cut second material belt, and the first adsorption seat 221 and the second adsorption seat 231 are far away from each other, so that the first material belt a can pass between the first adsorption seat 221 and the second adsorption seat 231 along with the cut second material belt, and then is conveyed downstream. It should be understood that the second adsorption seat 231 may adsorb the second material belt before the cutting mechanism 24 cuts the second material belt, or after the cutting mechanism 24 cuts the second material belt, which is not limited herein.
In some embodiments, the side of the first adsorption seat 221 facing the second adsorption seat 231 further has a third adsorption region 2213 and a fourth adsorption region 2214, the third adsorption region 2213 is located upstream of the first adsorption region 2211, and the fourth adsorption region 2214 is located upstream of the second adsorption region 2212.

When the first adsorption seat 221 is located at the first position, the first pressing end 241 is used for pressing the second material belt against the second adsorption area 2212. Thus, after the reel change is completed, the first web a is conveyed downstream through between the first suction seat 221 and the second suction seat 231. In order to prepare for the next reel change, the beginning end of the second material belt unreeled and output by the second unreeling mechanism 12 can be tightly pressed in the second adsorption area 2212 by utilizing the expansion and contraction of the first material pressing end 241, so that the second material belt is prevented from being adsorbed by the second adsorption area 2212 all the time, the second material belt is only required to be adsorbed by the second adsorption area 2212 in the reel change process, the loss of an air source is reduced, and the energy-saving effect is achieved.
When the first adsorption seat 221 is located at the second position, the second pressing end 251 is configured to press the first material belt against the first adsorption area 2211.

In order to prepare for the next reel change, the beginning end of the first material belt a unreeled and output by the first unreeling mechanism 11 can be tightly pressed on the first adsorption area 2211 by utilizing the expansion and contraction of the second material pressing end 251, so that the first material belt a is prevented from being adsorbed by the first adsorption area 2211 all the time, the first material belt a is only required to be adsorbed by the first adsorption area 2211 in the reel change process, the loss of an air source is reduced, and the energy-saving effect is realized.
In particular embodiments, the first belt press 24 includes a first belt drive 242 and a first belt press block. The first belt pressing driving member 242 is mounted on the mounting seat 21, and the first belt pressing block is mounted on the driving end of the first belt pressing driving member 242 and serves as a first material pressing end 241 of the first belt pressing mechanism. The first belt driving member 242 is configured to drive the first belt block to reciprocate along the first direction. The first belt pressing block can press the second belt to the second adsorption area 2212 in the process of moving along the first direction. Alternatively, the first belt drive 242 may be an air cylinder. The first belt driving member 242 may be mounted to the mounting base 21 through the first base 245.
In particular, in the embodiment, the second belt pressing mechanism 25 includes a second belt pressing driving member and a second belt pressing block. The second belt pressing driving member is mounted on the mounting seat 21, and the second belt pressing block is mounted on the driving end of the second belt pressing driving member and serves as a second material pressing end 251 of the second belt pressing mechanism. The second belt pressing driving piece is used for driving the second belt pressing block to move back and forth along the first direction. The second belt pressing block can press the first belt to the first adsorption area 2211 in the process of moving along the first direction. Alternatively, the second belt drive may be a pneumatic cylinder. The second belt-pressing driving member may be mounted to the mounting base 21 through a second base.
In particular, in the embodiment, the roll changing assembly further includes a first cutter 26 disposed on the first belt pressing mechanism 24, where the first cutter 26 is configured to cut off the leading end of the second belt pressed by the first pressing end 241 to the second adsorption area 2212, so that the leading end of the second belt is kept neat, so as to be adhered to the cut end of the first belt a during roll changing, and improve the belt joining effect.
The roll changing assembly further comprises a second cutting knife 27 arranged on the second belt pressing mechanism 25, wherein the second cutting knife 27 is used for cutting off the starting end of the first material belt a pressed on the first adsorption area 2211 by the second material pressing end 251, so that the starting end of the first material belt a is kept neat, and is convenient to be adhered to the cutting end of the second material belt during roll changing, and the belt connecting effect is improved.
More specifically, the first belt pressing mechanism 24 further includes a first moving seat 243 and a first elastic buffer 244. The first moving seat 243 is connected to the driving end of the first belt driving member 242, and the first belt driving member 242 is used for driving the first moving seat 243 to reciprocate along the first direction. The first belt pressing block is movably connected to the first moving seat 243 along a first direction, and the first elastic buffer 244 is disposed between the first moving seat 243 and the first belt pressing block to provide a pre-tightening force for enabling the first belt pressing block to have a movement trend away from the first moving seat 243 along the first direction. The first belt pressing block can press the second belt to the second adsorption area 2212 in the process of moving along the first direction along with the first moving seat 243, and meanwhile, the first elastic buffer 244 can be compressed to play a role of buffering.
The first cutter 26 is mounted to the first moving seat 243 of the first belt pressing mechanism 24 to move synchronously with the first moving seat 243 in the first direction. Thus, when the second material belt needs to be pressed, the first belt pressing driving member 242 drives the first moving seat 243 to move along the first direction near the second adsorption area 2212, so as to drive the first belt pressing block to contact with the second material belt, and further press the second material belt to the second adsorption area 2212. Then, the first belt pressing driving member 242 continues to drive the first moving seat 243 to move along the first direction near the second adsorption area 2212, so as to compress the first elastic buffer member 244, and further drive the first cutting blade 26 to move toward the second material belt until the first cutting blade 26 cuts the beginning end of the second material belt. Alternatively, the first elastic buffer 244 may be a spring. The first belt pressing block may be mounted on the first moving seat 243 through a guide rod and a guide sleeve, so that the first belt pressing block is movable along a first direction relative to the first moving seat 243 under the guiding action of the guide rod and the guide sleeve.
The second belt pressing mechanism 25 further includes a second moving seat and a second elastic buffer. The second movable seat is connected to the driving end of the second belt pressing driving piece, and the second belt pressing driving piece is used for driving the second movable seat to reciprocate along the first direction. The second belt pressing block is movably connected to the second moving seat along the first direction, and the second elastic buffer piece is arranged between the second moving seat and the second belt pressing block so as to provide a pretightening force for enabling the second belt pressing block to have a movement trend away from the second moving seat along the first direction. The second belt pressing block can press the first material belt a to the first adsorption area 2211 in the process of moving along the first direction along with the second moving seat, and meanwhile, the second elastic buffer piece can be compressed to play a role in buffering.
The second cutoff knife 27 is mounted to the second movable seat of the second belt press 25 to move synchronously with the second movable seat in the first direction. Therefore, when the first material belt a needs to be pressed, the second belt pressing driving member drives the second moving seat to move along the first direction near the first adsorption area 2211, so as to drive the second belt pressing block to contact with the first material belt a, and further press the first material belt a to the first adsorption area 2211. Then, the second belt pressing driving member continues to drive the second moving seat to move along the first direction near the first adsorption area 2211, so as to compress the second elastic buffer member, and further drive the second cutting knife 27 to continue to move towards the first material belt a until the second cutting knife 27 cuts off the starting end of the first material belt a. Alternatively, the second elastic buffer may be a spring. The second belt pressing block can be arranged on the second movable seat through the guide rod and the guide sleeve, so that the second belt pressing block can move along the first direction relative to the second movable seat under the guiding action of the guide rod and the guide sleeve.
It should be noted that, in other embodiments, the first cutter 26 may be separately provided with a driving structure to drive the first cutter 26 to move along the first direction, so as to cut the leading end of the second material tape.
Of course, the second cutter 27 may be separately provided with a driving structure for driving the second cutter 27 to move in the first direction, thereby cutting the leading end of the first tape a.

The first driving member 223 is disposed on the mounting seat 21 and is in driving connection with the sliding seat 222 to drive the sliding seat 222 to move along the second direction, so as to drive the first adsorption seat 221 to move along the second direction, such that the first adsorption area 2211 and the second adsorption area 2212 on the first adsorption seat 221 are alternately aligned with the second adsorption seat 231 in the first direction. Optionally, the first driver 223 is a cylinder.
In the embodiment, the sliding base 222 is provided with a sliding block 2221, the mounting base 21 is provided with a sliding rail 211 extending lengthwise along the second direction, and the sliding base 222 is movably connected with the mounting base 21 along the second direction through sliding fit of the sliding block 2221 and the sliding rail 211.

The roller 225 is mounted on the sliding seat 222, the driving plate 224 is mounted on the driving end of the first driving member 223, and has a slot, and the roller 225 is clamped in the slot, so that the roller 225 moves along the second direction along with the driving plate 224. Thus, the driving end of the first driving member 223 drives the mounting plate to move along the second direction, and the driving plate 224 drives the sliding seat 222 to move along the second direction through the cooperation of the roller 225 and the clamping groove.
In one embodiment, the first suction mechanism 22 further includes a second driving member 226, and the first suction seat 221 is movably connected to the sliding seat 222 along the first direction. The second driving member 226 is fixedly disposed opposite to the sliding seat 222 and is in transmission connection with the first adsorption seat 221, so as to drive the first adsorption seat 221 to move along the first direction opposite to the sliding seat 222, thereby making the first adsorption seat 221 approach or separate from the second adsorption seat 231. Alternatively, the second driving member 226 may be a cylinder.
In particular embodiments, the roll changing device further includes a connecting plate 30, where the connecting plate 30 is fixedly connected to the sliding base 222 to move synchronously with the sliding base 222 along the second direction. The first unreeling mechanism 11 and the second unreeling mechanism 12 are arranged on the connecting plate 30 along the second direction. In this way, in the reel change process, the first unreeling mechanism 11 and the first material belt a and the second unreeling mechanism 12 which are unreeled and output by the first unreeling mechanism and the second material belt which is unreeled and output by the second unreeled mechanism can move synchronously along the second direction along the sliding seat 222, so that the beginning end of the first material belt a is adhered to the cutting end of the second material belt or the beginning end of the second material belt is adhered to the cutting end of the first material belt a during the reel change.
Further, the first unreeling mechanism 11 includes a first unreeling tray rotatably connected to the connecting plate 30 around its own axis for loading the reels of the first tape a. The second unreeling mechanism 12 comprises a second unreeling tray which is rotatably connected to the connecting plate 30 around its own axis, and which is used for mounting the reels of the second material tape.
Further, the first unreeling tray and the second unreeling tray are both rotatably connected to the connecting plate 30 through the rotating shaft 13. Alternatively, the rotation shaft 13 may be a slip shaft.
In the embodiment, the second driving member 226 is fixedly connected to the connecting plate 30 or the sliding seat 222 through the fixing seat 2261, so that the second driving member 226 is fixedly disposed relative to the sliding seat 222. Further, the first adsorption mechanism 22 further includes a limiting rod 227, and a limiting hole or a limiting groove is formed in the fixing base 2261. The limiting rod 227 is slidably fitted in the limiting hole or the limiting groove, and one end of the limiting rod 227 is fixedly connected with the first adsorption seat 221. More specifically, the end of the limiting rod 227 facing away from the first adsorption seat 221 has a limiting portion, and the limiting portion can be abutted against one side of the fixing seat 2261 facing away from the first adsorption seat 221 in the sliding process of the limiting rod 227 along the limiting hole or the limiting groove, so as to limit the moving range of the first adsorption seat 221 along the first direction.
In particular embodiments, the unwind assembly 10 further includes a first pass roller 14 and a second pass roller 15. The first roller 14 is rotatably connected to the connecting plate 30 around its own axis and is located between the first unreeling mechanism 11 and the reel changing assembly to guide the first material tape a unreeled and outputted by the first unreeling mechanism 11 between the first suction seat 221 and the second suction seat 231. The second roller 15 is rotatably connected to the connecting plate 30 around its own axis and is located between the second unreeling mechanism 12 and the reel changing assembly, so as to guide the second material strip unreeled and outputted by the second unreeling mechanism 12 between the first suction seat 221 and the second suction seat 231.
It should be noted that, in another embodiment, as shown in fig. 6 and 7, the sliding base 222 is only movable along the second direction by the first driving member 223, and is not movable along the first direction, that is, the first adsorbing base 221 is only movable along the second direction along with the sliding base 222, and is not movable along the first direction. At this time, the pressing of the first or second tape a is achieved only by the movement of the second adsorption seat 231 in the first direction. In this way, the parts such as the second driving part 226, the fixing seat 2261, the limiting rod 227 and the like are omitted, the structure is simplified, and the equipment cost is reduced.
Referring to fig. 1, in the embodiment of the invention, the second adsorption mechanism 23 further includes a lifting seat 232 and a third driving member 233. The lifting base 232 is movably connected to the mounting base 21 along the first direction, and the second adsorption base 231 is connected to the lifting base 232. The third driving member 233 is mounted on the mounting base 21 and is in transmission connection with the lifting base 232, so as to drive the lifting base 232 to move along the first direction, and thereby drive the second adsorption base 231 to approach or separate from the first adsorption base 221 along the first direction. Alternatively, the third driving member 233 may be a cylinder.
Referring to fig. 1 and 5, in some embodiments, the cutting mechanism 24 includes a guide base 241, a cutter 242 and a fourth driving member 245, and the cutter 242 is mounted on the guide base 241. The fourth driving member 245 is mounted on the lifting seat 232 or the mounting seat 21 and is in transmission connection with the guiding seat 241, so as to drive the guiding seat 241 to move along the first direction, and further drive the cutter 242 to move along the first direction. In this way, when the second adsorption seat 231 and the first adsorption seat 221 clamp the first material belt a or the second material belt during the reel change, the fourth driving member 245 drives the guide seat 241 to move along the first direction and drives the cutter 242 to move along the first direction, so that the cutter 242 cuts the clamped first material belt a or second material belt during the moving along the first direction. Alternatively, the fourth driving member 245 may be a cylinder.
Further, the first suction seat 221 is provided with a cutter groove 2215 corresponding to the cutter 242, so that when the cutter 242 moves towards the first suction seat 221 along the first direction to cut the first material belt a or the second material belt, the cutter 242 cuts into the cutter groove 2215, thereby preventing the cutter 242 from contacting the first suction seat 221 to be damaged. Further, a cutter groove 2215 is formed between the first adsorption area 2211 and the third adsorption area 2213, and a cutter groove 2215 is also formed between the second adsorption area 2212 and the fourth adsorption area 2214.
In particular, in an embodiment, the cutting mechanism 24 further includes a pressing block 243 and an elastic member 245. The pressing block 243 is movably coupled to the guide holder 241 in a first direction and is located upstream of the cutter 242. That is, the cutter 242 is located between the pressing block 243 and the second adsorption seat 231. The elastic member 245 is disposed between the pressing block 243 and the guide holder 241 to provide a pre-tightening force that makes the pressing block 243 have a approaching trend toward the first adsorption holder 221 in the first direction. Thus, after the lifting seat 232 drives the second adsorption seat 231 to approach the first adsorption seat 221 and clamp the first material belt a or the second material belt, the fourth driving member 245 drives the guiding seat 241 to drive the cutter 242 and the pressing block 243 to approach the first adsorption seat 221, so that the pressing block 243 presses the first material belt a or the second material belt to the first adsorption seat 221 (at this time, the elastic member 245 is compressed), and then the cutter 242 cuts the first material belt a or the second material belt. Alternatively, the elastic member 245 may be a spring.
It should be noted that, in the process that the guide holder 241 drives the cutter 242 and the pressing block 243 to approach the first adsorption holder 221, the guide holder 241 compresses the first material belt a or the second material belt on the first adsorption holder 221, and then the cutter 242 contacts the first material belt a or the second material belt, so as to cut off the first material belt a or the second material belt.
Further, the cutting mechanism 24 further includes a guide rod 244, the guide rod 244 is slidably matched with the guide seat 241, and the pressing block 243 is fixedly connected with one end of the guide rod 244 facing the first adsorption seat 221. More specifically, the guide holder 241 is provided with a guide hole through which the guide rod 244 is inserted and slidably engaged with the guide hole. One end of the guide rod 244 away from the pressing block 243 is positioned on one side of the guide seat 241 away from the pressing block 243, and is connected with a limiting block 2411. In the process that the guide rod 244 slides along the first direction relative to the guide seat 241, the limiting block can abut against one side of the guide seat 241 away from the pressing block 243, so as to limit the moving range of the guide rod 244 along the first direction. Alternatively, the guide rod 244 may include two or more.
In particular, in an embodiment, the reel changer further includes a detector 40 disposed on the second adsorption mechanism 23, where the detector 40 is configured to detect an unreeling condition of the reel on the first unreeling mechanism 11 when the first adsorption seat 221 is located at the first position, or detect an unreeling condition of the reel on the second unreeling mechanism 12 when the first adsorption seat 221 is located at the second position, so that when the detector 40 detects that unreeling of the reel on the first unreeling mechanism 11 or the second unreeling mechanism 12 is completed, the first adsorption mechanism 22, the second adsorption mechanism 23 and the cutting mechanism 24 perform a reel change operation. Optionally, the detector 40 is mounted on a guide holder 241. The detector 40 may be a photosensor.
Referring to fig. 1 and 2, the first suction seat 221 is located at the first position, the beginning end of the second material belt unreeled and output by the second unreeled mechanism 12 is pressed by the first pressing end 241 of the first belt pressing mechanism 24 to the second suction area 2212, and the first material belt a unreeled and output by the first unreeled mechanism 11 passes through the first suction seat 221 and the second suction seat 231 and is conveyed to the initial state downstream, so as to describe the reel changing process of the reel changing device:
When the unreeling of the material roll on the first unreeling mechanism 11 is completed and the reel replacement is needed, first, the first suction holder 221 and the second suction holder 231 are close to each other under the driving of the second driving member 226 and the third driving member 233, respectively (or in an embodiment in which the first suction holder 221 cannot move along the first direction, the second suction holder 231 is close to the first suction holder 221 under the driving of the third driving member 233), so as to clamp the first material tape a.
Then, the fourth driving member 245 drives the guide holder 241 to approach the first adsorption holder 221, so that the pressing block 243 presses the first material belt a, and as the guide holder 241 continues to approach the first adsorption holder 221, the cutter 242 cuts off the first material belt a. After the first tape a is cut, the fourth driving member 245 drives the guide holder 241 to reset.
Then, at this time, the cut end of the first tape a is adsorbed by the second adsorption seat 231, the end of the first tape a connected to the roll is adsorbed by the third adsorption area 2213, and the leading end of the second tape unwound and output by the second unwinding mechanism 12 is adsorbed by the second adsorption area 2212. The second driving member 226 drives the first suction holder 221 away from the second suction holder 231 along the first direction (or in an embodiment in which the first suction holder 221 cannot move along the first direction, the second suction holder 231 is driven by the third driving member 233 to move away from the first suction holder 221), and the first driving member 223 drives the first suction holder 221 to move along the second direction to the second position.
Then, the second driving member 226 drives the first suction holder 221 to approach the second suction holder 231 along the first direction (or in the embodiment in which the first suction holder 221 cannot move along the first direction, the second suction holder 231 approaches the first suction holder 221 under the driving of the third driving member 233), so that the cut end of the first material strip a sucked by the second suction holder 231 is adhered to the start end of the second material strip sucked by the second suction area 2212, thereby realizing the connection between the second material strip and the cut end of the first material strip a.
Finally, the second adsorption seat 231 releases the adsorption of the cut end of the first tape a, and the second adsorption area 2212 of the first adsorption seat 221 releases the adsorption of the leading end of the second tape. And, the second driving member 226 and the third driving member 233 respectively drive the first suction holder 221 and the second suction holder 231 away from each other (or in an embodiment in which the first suction holder 221 cannot move in the first direction, the second suction holder 231 is far away from the first suction holder 221 under the driving of the third driving member 233), so that the second material tape can be conveyed downstream through between the first suction holder 221 and the second suction holder 231.
The roll on the first roll changing mechanism 11 is changed, and the beginning end of the first material belt a unreeled and output by the first roll changing mechanism 11 is pressed by the second pressing end 251 of the second belt pressing mechanism 25 to the first adsorption area 2211, so that preparation is made for the next roll changing. When the unreeling of the material roll on the second unreeling mechanism 12 is completed, the step of replacing the roll again is similar to the above-mentioned step of replacing the roll, so that the description thereof will be omitted.
