Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Injection molding machines are used as the primary molding equipment for forming molded parts of various shapes. At present, in the feeding and discharging procedures of an injection molding machine, feeding and discharging of plastic parts are generally carried out by an artificial carrying bin. The loading and unloading operation comprises a loading procedure and an unloading procedure. For example, after the injection molding machine completes the injection molding work, the bin is manually transported from the target position to the injection molding machine, and after the manufactured plastic part is filled with the bin, the feeding process is completed. After the feeding process is finished, the material box filled with plastic parts is manually conveyed to a target position, and after the plastic parts in the material box are removed (manually or in other modes), the discharging work of the injection molding machine is finished. After the blanking process of the injection molding machine is completed, the discharged material box (empty box) needs to be carried to the injection molding machine again by manpower so as to facilitate the installation of the plastic part in the material box in the next feeding process.

The feeding and discharging procedures of the injection molding machine are carried out through the manual conveying material box, so that the automation degree of the injection molding machine in the feeding and discharging operation process is low, and in the feeding and discharging procedures, the defects of long conveying paths and the like exist, so that the conveying efficiency of plastic parts in the feeding and discharging procedures is low.

For this reason, in the related art, an automatic conveyance carriage (Automated Guided Vehicle, AGV) is used instead of a manual conveyance of the magazine. Compared with a manual conveying mode, the automatic conveying device has the advantages that the conveying efficiency and the automation degree of plastic parts in the feeding and discharging working procedures of the injection molding machine can be improved to a certain extent, the labor cost is reduced, the defects of long conveying paths and the like still exist, and the automation degree and the conveying efficiency of feeding and discharging operation of the injection molding machine are still to be improved.

Therefore, how to improve the conveying efficiency and the automation degree of the injection molding machine in the feeding and discharging processes has become a technical problem to be solved.

In view of the above, the present disclosure provides an injection molding machine feeding and discharging system, in which an injection molding machine is in butt joint with a transfer robot through a box transfer mechanism and a box transfer mechanism, so that when the feeding and discharging operation of the injection molding machine is completed, compared with the feeding and discharging procedures of the existing injection molding machine, the feeding and discharging system of the injection molding machine can have higher automation degree, and the transfer path of the transfer robot is reduced, so that the transfer efficiency in the feeding and discharging operation and the safety of plastic parts are improved.

The structure of the feeding and discharging system of the injection molding machine of the present disclosure will be further described below with reference to the accompanying drawings and examples.

Fig. 1 and 2 show schematic structural diagrams of a feeding and discharging system of an injection molding machine at different viewing angles.

Referring to fig. 1 and 2, the injection molding machine loading and unloading system 100 includes an injection molding machine 110, a box transfer mechanism 120, a box transfer mechanism 130, and a transfer robot 140. The box transferring mechanism 120 includes a mechanism body 121 and a moving platform 122 for placing the box 200. The box 200 is configured to bear the plastic part made by the injection molding machine 110, so that the plastic part made by the injection molding machine 110 after injection molding can be borne in the box 200, and blanking of the plastic part is realized through the box 200. Wherein the case 200 may include, but is not limited to, the above-described bin, and the structure of the case 200 is not further limited in this disclosure.

The moving platform 122 is connected to the mechanism body 121, and is disposed to move relative to the mechanism body 121. The moving platform 122 is located between the injection molding machine 110 and the first transfer end 1311 of the case transfer mechanism 130 and interfaces with the case transfer mechanism 130 so that the moving platform 122 can move to a different position of the case transfer mechanism 130 with respect to the mechanism body 121 and interfaces with the case transfer mechanism 130 to transfer the case 200 loaded with the molded article onto the case transfer mechanism 130 at the first transfer end 1311 or to receive the case 200 transferred onto the case transfer mechanism 130 at the first transfer end 1311.

Referring to fig. 1 and 2, the transfer robot 140 is located at the second transfer end 1312 of the box transfer mechanism 130, and is configured to perform a transfer operation of the box 200 at the second transfer end 1312. The transfer work may include the transfer robot 140 taking the box 200 on the box transfer mechanism 130 at the second transfer end 1312 or transferring and placing the box 200 at the second transfer end 1312 of the box transfer mechanism 130.

The present disclosure enables the injection molding machine 110 to interface with the transfer robot 140 through the case transfer mechanism 120 and the case transfer mechanism 130 through the case transfer mechanism 130, the transfer robot 140, and the setting of the moving platform 122. After the injection molding of the injection molding machine 110 is completed, the moving platform 122 can move to the first transmission end 1311 and is in butt joint with the box body transmission mechanism 130, and the plastic parts are installed in the box body 200 of the moving platform 122 in a manual or mechanical arm mode, so that the feeding operation of the feeding and discharging system 100 of the injection molding machine is completed.

Because the mobile platform 122 is in butt joint with the box body transmission mechanism 130, the box body 200 provided with the plastic part after the feeding operation can be transported to the box body transmission mechanism 130. After the box 200 is transferred to the second transfer end 1312, the transfer robot 140 can automatically perform a transfer operation at the second transfer end 1312, and transfer the box 200 with the plastic part to the target position, which is beneficial to completing the blanking operation of the injection molding machine 110. After the case 200 is carried to the target position, the plastic part in the case 200 may be removed manually or by a manipulator, and at this time, the blanking operation of the injection molding machine loading and unloading system 100 is completed.

After the blanking operation is completed, the next feeding operation is started. At this time, the transfer robot 140 automatically performs the transfer operation of the box 200 at the second transfer end 1312, transfers the box 200 (empty box) from which the plastic is removed to the second transfer end 1312, and when the moving platform 122 moves to butt joint with the first transfer end 1311, the empty box can be transferred again to the moving platform 122 via the box transfer mechanism 130, thereby realizing the recovery of the empty box on the moving platform 122. When the moving platform 122 moves to be in butt joint with the box body transmission mechanism 130 again and the plastic part is arranged in the box body 200, the next blanking operation starts. In this way, the plastic parts can be continuously discharged through the circulation movement of the box 200 on the box conveying mechanism 130 and the moving platform 122.

Compared to the current loading and unloading process (such as manual handling or automatic handling of a trolley) of the injection molding machine 110, the box 200 in the loading and unloading system 100 of the injection molding machine of the present disclosure can be automatically transferred to the box conveying mechanism 130 via the moving platform 122, or automatically transferred to the moving platform 122 via the box conveying mechanism 130, so that the loading and unloading system 100 of the injection molding machine has a higher degree of automation.

And, by the arrangement of the box transporting mechanism 130 and the box transferring mechanism 120, the box 200 can be temporarily stored on the box transporting mechanism 130. In this way, the transfer robot 140 can perform the transfer operation of the box 200 only at the second transfer end 1312. Compared to manual handling or automatic handling dollies, the handling path of the handling robot 140 can be reduced, the handling efficiency of the handling robot 140 in loading and unloading operations (handling efficiency for plastic parts) and the safety of the plastic parts can be improved, and the waiting time of the handling robot 140 when the second transmission end 1312 performs the handling operation of the box 200 can be reduced, so that the handling efficiency of the handling robot 140 in loading and unloading operations (loading operations and unloading operations) can be further improved.

In the loading and unloading operation of the current injection molding machine 110, the path of the manual or automatic carrying trolley carrying the material box is longer, so that the management difficulty of the plastic parts in the carrying process is higher, and the safety of the plastic parts in the loading and unloading operation is reduced.

The feeding and discharging system 100 of the injection molding machine reduces the carrying path of the carrying robot 140, so that compared with the mode that the carrying robot 140 can carry the material box manually or automatically, the management difficulty of plastic parts in the carrying process can be reduced, and the safety of the plastic parts in the feeding and discharging operation is enhanced.

In the loading and unloading operation of the current injection molding machine 110, no matter the feeding boxes are manually carried or the feeding boxes are carried by an automatic carrying trolley, because the quantity of the feeding boxes carried each time is limited (for example, 1), the defect of high feeding frequency is caused in the loading and unloading operation of the current injection molding machine 110, the carrying efficiency is reduced, and the management difficulty of plastic parts is increased.

For this purpose, referring to fig. 1, the transfer robot 140 includes a moving chassis 141 and a storage mechanism 142, the storage mechanism 142 includes a pillar 1421 and a plurality of storage units 1422, the pillar 1421 is provided on the moving chassis 141, and the plurality of storage units 1422 are provided at intervals in a height direction of the pillar 1421. Through the arrangement of the plurality of storage units 1422, the transfer robot 140 performs the transfer operation of the box 200 at the second transmission end 1312, and can take a plurality of temporary storage boxes 200 at the second transmission end 1312 at a time, and temporarily store the plurality of boxes 200 in the plurality of storage units 1422 and then transfer the temporary storage boxes to the target position.

Alternatively, after the blanking operation is completed, the transfer robot 140 may be further configured to place the plurality of empty boxes to be transferred at the second transfer end 1312 at a time. In this way, the frequency of taking and feeding of the transfer robot 140 in the loading and unloading operation can be reduced, and the transfer efficiency of the transfer robot 140 in the loading and unloading operation can be further improved.

Where the case 200 is a bin, the transfer robot 140 may be a bin robot, and the storage unit 1422 may be understood as a pack basket of the bin robot.

Referring to fig. 1, the transfer robot 140 further includes a fork device 143, where the fork device 143 has a telescopic arm assembly 1431 and a robot finger module (not shown in the drawing), and the telescopic arm assembly 1431 is movable relative to a bottom plate (not shown in the drawing) of the fork device 143 along a moving direction of a cargo (such as the box 200) within the fork device 143, and the robot finger module is located at a side of a cargo access opening of the fork device 143 and is rotatable relative to the bottom plate. When the transfer robot 140 takes the box 200 at the first transfer end 1311, the telescopic arm assembly 1431 may move relative to the bottom plate of the fork device 143 and extend out of the bottom plate so that the box 200 on the first transfer end 1311 is positioned within the telescopic arm assembly 1431 (as shown in fig. 1). At this time, the robot finger module may rotate to a side of the box 200 away from the handling robot 140, and under the combined action of the robot finger module and the telescopic arm assembly 1431, the box 200 on the first transmission end 1311 may be handled into the fork device 143.

Because the fork assembly 143 is rotatably disposed relative to the mobile chassis 141, the fork assembly 143 can rotate relative to the mobile chassis 141 and transfer the bin 200 into the storage unit 1422 via the telescopic arm assembly 1431.

Because the fork device 143 is rotatably disposed relative to the movable chassis 141 and is movably disposed along the height direction of the upright post 1421, the plurality of the fetched boxes 200 can be placed in different storage units 1422 by moving the fork device 143 on the upright post 1421, thereby realizing the fetching and temporary storage of the boxes 200 by the transfer robot 140. The height direction of posts 1421 may be referred to as the Y direction in fig. 1.

The fork device 143 can also move relative to the base plate through the telescopic arm assembly 1431 to place the temporary storage box 200 at the target position or the first transmission end 1311, so as to realize the conveying function of the conveying robot 140 on the box 200.

It should be noted that, the structure of the fork device 143 and the carrying action of the box 200 can refer to the related description of the bin robot in the related art, and will not be further described herein.

Referring to fig. 1 and 2, the case transfer mechanism 130 includes a frame 131, a discharging transfer assembly 132, and a feeding transfer assembly 133. The discharging transmission assembly 132 and the feeding transmission assembly 133 are configured to transmit the box 200 along different transmission directions, and the first transmission end 1311 and the second transmission end 1312 are disposed at opposite ends of the frame 131. The blanking transmission assembly 132 and the feeding transmission assembly 133 are disposed on the frame 131 and located between the first transmission end 1311 and the second transmission end 1312, so that transmission ports corresponding to the blanking transmission assembly 132 and the feeding transmission assembly 133 are disposed on the first transmission end 1311 and the second transmission end 1312, and when the moving platform 122 moves relative to the mechanism body 121, the moving platform can be abutted with different transmission ports of the first transmission end 1311, so that the box 200 is transferred onto the box transmission mechanism 130, or the box 200 on the box transmission mechanism 130 is received.

For convenience of description, the transmission port corresponding to the first transmission port 1311 and the blanking transmission assembly 132 is defined as a first transmission port, the transmission port corresponding to the second transmission port 1312 and the blanking transmission assembly 132 is defined as a second transmission port, the transmission port corresponding to the second transmission port 1312 and the feeding transmission assembly 133 is defined as a third transmission port, and the transmission port corresponding to the first transmission port 1311 and the feeding transmission assembly 133 is defined as a fourth transmission port.

Through the setting of unloading transmission subassembly 132 and material loading transmission subassembly 133, install the box 200 of moulding can be along unloading transmission subassembly 132 and material loading transmission subassembly 133 one of transmission to second transmission end 1312, the box 200 after removing the moulding can be along unloading transmission subassembly 132 and material loading transmission subassembly 133 another one of transmission to first transmission end 1311 to avoid the box 200 in unloading operation and the material loading operation to interfere each other.

Meanwhile, when the moving platform 122 moves relative to the mechanism body 121, the moving platform 122 can be in butt joint with different transmission ports of the first transmission end 1311, so that the movement of the moving platform 122 can realize the transfer of the box 200 between different transmission ports (such as the first transmission port and the fourth transmission port) of the first transmission end 1311, thereby realizing the cyclic movement of the box 200 on the box transmission mechanism 130 and the box transfer mechanism 120 and continuously discharging plastic parts.

Referring to fig. 2, the discharging and transporting assembly 132 is configured to transport the case 200 with the plastic part from the first transporting end 1311 to the second transporting end 1312, so that the case 200 with the plastic part can be transported from the first transporting end 1311 to the second transporting end 1312 by the discharging and transporting assembly 132, so that the handling robot 140 takes the case 200 on the second transporting port (the material taking port) of the second transporting end 1312.

In the loading operation, the moving platform 122 can move to the first conveying port (loading port) of the first conveying end 1311 relative to the mechanism body 121, and is in butt joint with the unloading conveying assembly 132, so that after the plastic part is conveyed into the box 200 through the first conveying port in a manual or mechanical arm mode or the like, the box 200 can be directly conveyed onto the unloading conveying assembly 132 through the first conveying port, so as to realize the unloading operation.

With continued reference to fig. 2, the feeding and conveying assembly 133 is configured to convey the box 200 (empty box) from which the plastic is removed from the second conveying end 1312 to the first conveying end 1311, so that the empty box can be conveyed from the second conveying end 1312 to the first conveying end 1311 under the action of the feeding and conveying assembly 133. When the moving platform 122 moves to the fourth transmission port of the first transmission end 1311 relative to the mechanism body 121 and is in butt joint with the feeding transmission assembly 133, the box 200 can be transferred to the moving platform 122 at the fourth transmission port, and the empty box is transferred to the position of the first transmission port through the movement of the moving platform 122, so that after the plastic part is installed in the empty box, the blanking operation is performed again, and the carrying robot 140 can take the box 200 at the second transmission port (material taking port) of the second transmission end 1312.

In the loading operation, the transfer robot 140 may transfer the empty box to the third transfer port (the discharge port) of the second transfer port 1312, so that the empty box can be transferred from the third transfer port of the second transfer port 1312 to the fourth transfer port of the first transfer port 1311 on the loading transfer assembly 133.

Fig. 3 illustrates an assembly schematic of a case transfer mechanism and a case transfer mechanism.

Referring to fig. 3, in some embodiments, the blanking and loading transfer assemblies 132 and 133 each include at least one fluent strip unit 134, the fluent strip unit 134 being disposed obliquely to the frame 131. The lower end of the flow strip unit 134 in the blanking conveying assembly 132 faces the second conveying end 1312, so that the box 200 can slide from the first conveying end 1311 to the first conveying end 1311 on the blanking conveying assembly 132 under the action of self gravity. The higher end of the flow strip unit 134 in the feeding and conveying assembly 133 faces the second conveying end 1312, so that the box 200 can slide from the second conveying end 1312 to the first conveying end 1311 on the feeding and conveying assembly 133 under the action of self gravity.

The fluency strip unit 134 includes at least two fluency strips that are disposed on the chassis 131 at intervals in the width direction along the chassis 131 to form the fluency strip unit 134.

The number of the flow-promoting units 134 in the discharging and feeding transfer units 132 and 133 may be two, three or more. In the present disclosure, the number of the fluent strip units 134 in the discharging and feeding transport assemblies 132 and 133 is not further limited.

In this way, the box 200 can be transferred on the blanking transfer assembly 132 and the feeding transfer assembly 133 by arranging at least two fluent strip units 134 in the blanking transfer assembly 132 and the feeding transfer assembly 133. Moreover, since the fluent strip unit 134 at the transmission end is rotatably disposed on the rack 131, the box 200 of the blanking transmission assembly 132 and the feeding transmission assembly 133 in the transmission direction can generate a relative distance, so as to avoid interference between the box 200 at the rear end of the transmission direction and the box 200 at the front end of the transmission direction, and influence the picking of the box 200 by the transfer robot 140 or the carrying of the box 200 by the moving platform 122.

The conveying direction of the discharging conveying assembly 132 may be referred to an X-direction in fig. 3, and the conveying direction of the feeding conveying assembly 133 may be referred to an x+ direction in fig. 3.

Taking the blanking transfer assembly 132 (as shown in fig. 3 and 4) having two fluency strip units 134 as an example, the two fluency strip units 134 in the blanking transfer assembly 132 may be defined as a first fluency strip unit 1341 and a second fluency strip unit 1342 for convenience of description. The first fluent strip unit 1341 is located at the conveying start end of the blanking conveying assembly 132 and corresponds to the first conveying port, and the second fluent strip unit 1342 is located at the conveying end of the blanking conveying assembly 132 and corresponds to the second conveying port.

When a plurality of boxes 200 are transferred on the blanking transfer assembly 132 and the boxes 200 at the front end in the transfer direction are transferred onto the second fluent strip unit 1342, the second fluent strip unit 1342 can rotate on the frame 131 around the rotation axis o1 of the second fluent strip unit 1342 under the driving of gravity of the boxes 200, so that the transfer start end of the second fluent strip unit 1342 can swing to a position higher than the frame 131 to block the transfer of the boxes 200 (boxes 200 at the rear end in the transfer direction) on the first fluent strip unit 1341 and generate an opposite interval with the boxes 200 on the second fluent strip unit 1342, so as to avoid interference with the boxes 200 at the rear end in the transfer direction when the transfer robot 140 takes the boxes 200 at the second transfer port of the second transfer end 1312, and influence the taking of the boxes 200 by the transfer robot 140.

When the transfer robot 140 receives a command for taking the box 200, the box 200 on the second flow rate unit 1342 can be taken out at the second transfer port by the fork device 143 and placed in the storage unit 1422. After the fork device 143 takes out the box 200 on the second fluent strip unit 1342, the second fluent strip unit 1342 can rotate and reset relative to the rack 131 and is in butt joint with the first fluent strip unit 1341 so as to realize the transmission function of the blanking transmission assembly 132 on the box 200, so that the box 200 at the transmission rear end on the blanking transmission assembly 132 can flow down along the blanking transmission assembly 132 until the transfer robot 140 finishes taking all the boxes 200 on the blanking transmission assembly 132.

In order to facilitate automatic resetting of the second fluent strip unit 1342, the front transmission end of the second fluent strip unit 1342 may be connected to the frame 131 through the resetting member 136 (as shown in fig. 4), so that after the box 200 is taken out, the second fluent strip unit 1342 may rotate in an opposite direction relative to the frame 131 under the driving of the resetting member 136, so that the front transmission end of the second fluent strip unit 1342 may rotate to an initial position and interface with the first fluent strip unit 1341, so as to implement the transmission function of the blanking transmission assembly 132 to the box 200. Wherein the return 136 may include, but is not limited to, a return spring.

It should be noted that, in some embodiments, a cylinder or other manner may be used to drive the second fluent strip unit 1342 to rotate and reset relative to the frame 131. The second fluent strip unit 1342 may be hinged or otherwise rotatably connected to the chassis 131, the position where the second fluent strip unit 1342 is hinged to the chassis 131 forming a rotation axis o1. In the present disclosure, the manner in which the second fluent strip unit 1342 is rotatably connected to the frame 131 and the manner in which it is reset to the frame 131 are not further limited.

As shown in fig. 4, a distance between the rotation axis o1 of the second fluent strip unit 1342 and the transport front end of the second fluent strip unit 1342 may be a first distance L1, and a distance between the rotation axis o1 of the second fluent strip unit 1342 and the transport end of the second fluent strip unit 1342 may be a second distance L2.

In some embodiments, the first distance L1 may be smaller than the second distance L2 such that the rotation axis o1 is disposed eccentrically between both ends of the second flow strip unit 1342 (as shown in fig. 4), so that the second flow strip unit 1342 can rotate relative to the frame 131 about the rotation axis o1 under the force of gravity of the case 200.

Alternatively, in other embodiments, the first distance L1 may be equal to the second distance L2 so that the rotation axis o1 is located at the center of symmetry of both ends of the second flow strip unit 1342, on the basis of ensuring that the second flow strip unit 1342 can rotate relative to the chassis 131 about the rotation axis o1 under the force of gravity of the case 200. In the present disclosure, no further limitation is made as to whether the rotation axis o1 is eccentrically disposed on the second fluent strip unit 1342.

Similarly, when a plurality of plastic-unloading cases 200 (empty cases) are transferred on the feeding and transferring assembly 133 and the empty case at the front end of the transferring direction is transferred to the fluent strip unit 134 at the transferring end, the fluent strip unit 134 at the transferring end is rotatably disposed on the frame 131, so that the fluent strip unit 134 at the transferring end can rotate around the rotation axis o1 of the empty case relative to the frame 131 under the driving of the gravity of the empty case and block the empty case at the rear end of the transferring direction, so that the empty case at the rear end of the transferring direction and the empty case at the front end of the transferring direction have a relative distance therebetween, thereby avoiding interference with the empty case at the rear end of the transferring direction when the moving platform 122 receives the empty case at the fourth transferring port of the first transferring end 1311, and affecting the receiving of the empty case by the moving platform 122.

It should be noted that, the arrangement and rotation of the flow strip unit 134 in the feeding and conveying assembly 133 on the frame 131 may refer to the related description in the discharging and conveying assembly 132, which is not further described herein.

With continued reference to fig. 3 and 4, in some embodiments, the box conveying mechanism 130 further includes a limiting unit 135 for blocking the conveying of the box 200, where the limiting unit 135 is disposed on the frame 131 at an end of the blanking conveying component 132 opposite to the second conveying end 1312 and an end of the feeding conveying component 133 opposite to the first conveying end 1311, so that the box 200 at front ends (at the second conveying port and the fourth conveying port) of the respective conveying directions of the blanking conveying component 132 and the feeding conveying component 133 is blocked by the limiting unit 135 to avoid the box 200 from flowing outside the blanking conveying component 132 and the feeding conveying component 133.

Referring to fig. 4, the limiting unit 135 includes a limiting member 1352 and a control member 1351, where the limiting member 1352 is rotatably connected to the frame 131, so that the limiting member 1352 can rotate relative to the frame 131 toward a side far away from the box 200, and unblock the box 200, so that the handling robot 140 can take the box 200 and receive an empty box by the moving platform 122.

The limiting unit 135 further includes a base (not labeled in the drawing) fixedly connected to the frame 131, and the limiting member 1352 may be hinged to the base, so as to realize a rotational connection between the limiting member 1352 and the frame 131. The retainer 1352 may include, but is not limited to, a retainer, and the structure of the retainer may refer to the structure shown in fig. 4, and particularly refer to the related description of the fluent strip shelf in the related art. In the present disclosure, the structure of the stopper 1352 and its rotational connection to the housing 131 are not further limited.

As shown in fig. 4, the control member 1351 is connected with the limiting member 1352, and can control the limiting member 1352 to rotate relative to the frame 131, so that the automation degree of the feeding and discharging system 100 of the injection molding machine can be enhanced while the rotation of the limiting member 1352 on the frame 131 is controlled by the control member 1351. Illustratively, the control member 1351 may be a return spring (as shown in fig. 4), a rotary cylinder, or other control structure, and the structure of the control member 1351 is not further limited in the disclosure.

Taking a return spring as an example, one end of the control member 1351 may be connected to the stopper 1352, and the other end may be connected to the housing 131. When the handling robot 140 takes the box 200 at the second transmission port, the fork device 143 drives the box 200 to move toward one side of the handling robot 140, and the box 200 acts on the limiting member 1352 when moving, and pushes the limiting member 1352 to rotate toward one side away from the box 200 relative to the frame 131. In this way, the carrying robot 140 is convenient to take the box 200, and the control member 1351 is driven to elastically deform when the limiting member 1352 rotates relative to the frame 131. After the fork 143 takes the case 200, the stoppers 1352 are rotated with respect to the housing 131 by the elastic force of the control members 1351 and restored to the original position (the position shown in fig. 4) so as to continue to block the case 200.

Fig. 5 is an enlarged view of the portion B in fig. 3.

Referring to fig. 5, after the moving platform 122 moves to the fourth transmission port and is in butt joint with the feeding transmission assembly 133, since the limiting member 1352 may be hinged to the base through a rotating shaft, the limiting member 1352 may be driven by a motor (not illustrated in the drawing) to rotate relative to the base and the frame 131, so as to release the blocking of the empty box by the limiting member 1352, so that the empty box may slide to the moving platform 122 under the action of gravity, thereby implementing the receiving of the empty box by the moving platform 122.

Similarly, when the limiting member 1352 rotates relative to the frame 131, the control member 1351 is driven to elastically deform. After the movable platform 122 receives the empty box, the limiting member 1352 will rotate relative to the frame 131 under the elastic force of the control member 1351, and return to the initial position, so as to continuously block the empty box.

As shown in fig. 1 to 3, in some embodiments, the discharging transmission assembly 132 and the feeding transmission assembly 133 are disposed at intervals in the height direction of the frame 131, so as to avoid the mutual interference of the case 200 on the discharging transmission assembly 132 and the feeding transmission assembly 133, and facilitate the cyclic movement of the case 200 on the case transmission mechanism 130.

The moving platform 122 is configured to move in the height direction of the mechanism body 121, the height direction of the mechanism body 121 is parallel to the height direction of the rack 131, so that the box 200 is transported to the blanking transmission assembly 132 from the feeding transmission assembly 133 through the movement of the moving platform 122 in the height direction of the mechanism body 121, the cyclic movement of the box 200 on the box transmission mechanism 130 and the moving platform 122 is ensured, plastic parts are continuously blanked, and meanwhile, the upper space of a workshop where the feeding and blanking system 100 of the injection molding machine is located can be fully utilized, so that the space utilization rate and the storage density of the workshop are improved.

In this case, the moving platform 122 may be referred to as a lifting platform, and the case transfer mechanism 120 may be referred to as a lifting mechanism.

It should be noted that, the box conveying mechanism 130 may also freely customize the corresponding length and height and the number of the feeding conveying assembly 133 and the discharging conveying assembly 132 according to the site area of the workshop, so as to enlarge the temporary storage number of the box conveying mechanism 130 to the box 200. The case transfer mechanism 130 in fig. 1 to 3 illustrates only one material transfer assembly and one material discharge transfer assembly 132, and does not constitute a limitation on the number of material discharge transfer assemblies 133 and 132.

In some embodiments, the blanking conveying assembly 132 and the feeding conveying assembly 133 may also be disposed at intervals in the width direction of the frame 131 on the basis that the space utilization of the workshops is not excessively limited in application. At this time, the moving platform 122 may be configured to move in the width direction of the mechanism body 121, the width direction of the mechanism body 121 and the height direction of the frame 131 being parallel.

The structure of the feeding and discharging system 100 of the injection molding machine of the present disclosure will be further described below by taking the movement of the moving platform 122 in the height direction of the mechanism body 121 as an example.

Referring to fig. 5, the mechanism body 121 includes a carrier 1211 and a moving assembly 1212, with the moving platform 122 disposed within the carrier 1211. The moving assembly 1212 is movably disposed on the carrier 1211 and connected to the moving platform 122, so as to drive the moving platform 122 to move on the mechanism body 121, so that the moving platform 122 can move to different positions of the first conveying end 1311 under the driving of the moving assembly 1212, thereby realizing the docking between the moving platform 122 and the blanking conveying assembly 132 or the blanking conveying assembly 132.

The moving assembly 1212 may be a lifting assembly, and the moving assembly 1212 is slidably disposed in the height direction of the carrier 1211 and connected to the moving platform 122, so that the moving platform 122 can be driven by the moving assembly 1212 to move in the height direction of the mechanism body 121. The height direction of the carrier 1211 is parallel to the height direction of the chassis 131.

Referring to fig. 5, the moving assembly 1212 may include at least one moving member 1213 slidably disposed in a height direction of the carrier 1211, and the moving member 1213 is connected to the moving platform 122 such that the moving platform 122 can move in the height direction of the mechanism body 121 under the driving of the moving member 1213.

Wherein the number of moving members 1213 may include, but is not limited to, two. Taking two moving members 1213 as an example, the two moving members 1213 may be located at two sides of the moving platform 122 and fixedly connected with the moving platform 122 (as shown in fig. 5), so that the moving platform 122 can move in the height direction of the mechanism body 121 under the driving of the moving members 1213, and meanwhile, the moving stability of the moving platform 122 can be enhanced.

The mechanism body 121 further includes a plurality of guide members 1214, where the plurality of guide members 1214 are uniformly disposed on two sides of the moving platform 122 and are connected to the carrier 1211. The guide 1214 extends in the same direction as the height direction of the carrier 1211. The moving member 1213 is slidably disposed with respect to the guide member 1214 in the extending direction along the guide member 1214 so that the moving direction of the moving member 1213 can be guided by the guide member 1214.

In some embodiments, as shown in fig. 5, the guide 1214 may be a cylinder assembly, the moving member 1213 may be a shuttle, and the guide 1214 and the moving member 1213 may together form a rodless cylinder to facilitate movement of the moving member 1213 over the guide 1214 while enhancing the automation of the injection molding machine loading and unloading system 100. Alternatively, in some embodiments, the guide 1214 and the mover 1213 may also constitute other structures, such as a linear motion structure with a rod cylinder, lead screw, or other mover 1213 capable of moving on the guide 1214, and the like. In the present disclosure, the structures of the guide 1214 and the mover 1213 are not further limited.

Fig. 6 and 7 illustrate partial schematic views of the cassette transport mechanism, respectively.

Referring to fig. 6 and 7, the moving platform 122 includes a fixed tray 1221 and a rotary tray 1222 in which the case 200 is placed, and the fixed tray 1221 is fixedly coupled to the moving platform 122. For example, the fixed tray 1221 may be fastened to the two moving members 1213 (shown in fig. 6) by a fastening means, such as a screw or a bolt, etc., to fix the moving platform 122 to the mechanism body 121. Both the fixed tray 1221 and the rotary tray 1222 are horizontal trays on the case transfer mechanism 120.

The rotating tray 1222 is rotatably connected to the top surface of the fixed tray 1221, and is configured to interface with the discharging transmission assembly 132 or the feeding transmission assembly 133 of the box transmission mechanism 130, so that the moving platform 122 interfaces with the discharging transmission assembly 132 through the rotating tray 1222, so that the box 200 can slide onto the discharging transmission assembly 132 under the action of gravity. Or, the docking of the mobile platform 122 and the feeding transmission assembly 133 can be realized through the rotating tray 1222, so that the empty box on the feeding transmission assembly 133 can slide onto the rotating tray 1222 under the action of gravity, and the receiving of the empty box by the mobile platform 122 is realized. The top surface of the fixed tray 1221 is understood to be the surface of the fixed tray 1221 facing away from the floor of the workshop.

Referring to fig. 6 and 7, the moving platform 122 further includes a hinge shaft 1227, the hinge shaft 1227 is provided on the top surface of the fixed tray 1221, and the rotary tray 1222 is hinged to the hinge shaft 1227 so that the rotary connection of the rotary tray 1222 on the fixed tray 1221 is achieved through the hinge shaft 1227.

Referring to fig. 6 and 7, the hinge shaft 1227 may be supported by a support base 1228 and fixed to the top surface of the fixed tray 1221. Mobile platform 122 also includes connectors 1223, and the number of connectors 1223 may be one, two, three, or more. Taking three connecting members 1223 as an example, the three connecting members 1223 may be sleeved on the hinge shaft 1227 along the axial direction of the hinge shaft 1227 and rotatably disposed with respect to the hinge shaft 1227, so that when the connecting members 1223 are fixedly connected with the rotary tray 1222, the hinge between the rotary tray 1222 and the hinge shaft 1227 can be achieved.

As shown in fig. 6 and 7, the mobile platform 122 further includes a driving assembly 1224, the driving assembly 1224 being disposed between the rotary tray 1222 and the fixed tray 1221 to drive the rotary tray 1222 to rotate relative to the rotary tray 1222. Thus, the rotary tray 1222 can rotate relative to the fixed tray 1221 about the hinge shaft 1227 under the driving of the driving component 1224, so that the rotary tray 1222 is obliquely disposed on the fixed tray 1221, and one end of the rotary tray 1222 facing the box transferring mechanism 120 can be docked with the blanking conveying component 132 or the feeding conveying component 133.

Referring to fig. 6 and 7, in some embodiments, the drive assembly 1224 may include a first drive member 1225 and a second drive member 1226, the first drive member 1225 and the second drive member 1226 being disposed on opposite sides of the rotary tray 1222, respectively, and each having telescoping ends 1229. The housing receiving direction can be seen in the w direction in fig. 5. The telescopic end 1229 is connected to one side of the rotary tray 1222 and is disposed at an angle (as shown in fig. 6) with the rotary tray 1222, so as to drive the rotary tray 1222 to rotate relative to the fixed tray 1221, so as to control the telescopic states of the telescopic ends 1229 of the first driving member 1225 and the second driving member 1226, so that the rotary tray 1222 is inclined in different directions relative to the fixed tray 1221, and the rotary tray 1222 is abutted to the feeding and discharging conveying assemblies 133 and 132.

The first driving member 1225 and the second driving member 1226 are disposed on opposite sides of the rotary tray 1222 in the receiving direction of the box, respectively, and each has a telescopic end 1229. The housing receiving direction can be seen in the w direction in fig. 5. Wherein the first driving member 1225 may be positioned at a side of the rotary tray 1222 toward the case transfer mechanism 130, and the second driving member 1226 may be positioned at a side of the rotary tray 1222 away from the case transfer mechanism 130.

When the moving platform 122 moves to the feeding and conveying assembly 133 under the action of the moving assembly 1212, the telescopic end 1229 of the first driving member 1225 is controlled to extend to jack up the corresponding side of the rotary tray 1222, or the telescopic end 1229 of the second driving member 1226 is controlled to retract to sink the corresponding side of the rotary tray 1222, so that the rotary tray 1222 is obliquely arranged on the fixed tray 1221 along the first direction and is abutted with the feeding and conveying assembly 133. The first direction may include, but is not limited to, a direction identical to a conveying direction of the case 200 on the feeding conveying assembly 133.

After the empty box slides to the rotary tray 1222 due to gravity, the telescopic end 1229 of the first driving member 1225 is controlled to retract, or the telescopic end 1229 of the second driving member 1226 is controlled to extend, so that the rotary tray 1222 is reset and restored to the original position, and is in a horizontal state on the box transfer mechanism 120 (as shown in fig. 6 and 7).

In the process that the moving platform 122 moves from the feeding and conveying assembly 133 to the discharging and conveying assembly 132 under the action of the moving assembly 1212, the rotating trays 1222 are all in a horizontal state, so as to enhance the stability of the empty boxes received.

When the moving platform 122 moves to the blanking conveying assembly 132, the telescopic end 1229 of the second driving member 1226 is controlled to extend to jack up the corresponding side of the rotary tray 1222, or the telescopic end 1229 of the first driving member 1225 is controlled to retract to sink down the corresponding side of the rotary tray 1222, so that the rotary tray 1222 is obliquely arranged on the fixed tray 1221 along the second direction and is in butt joint with the blanking conveying assembly 133. The second direction is opposite to the first direction.

After the empty box slides to the rotary tray 1222 due to gravity, the telescopic end 1229 of the second driving member 1226 is controlled to retract, or the telescopic end 1229 of the first driving member 1225 is controlled to extend, so that the rotary tray 1222 is reset and restored to the original position, and is in a horizontal state on the box transfer mechanism 120 (as shown in fig. 6 and 7).

In some embodiments, the first driving member 1225 and the second driving member 1226 are telescopic cylinders, so that the automation degree of the feeding and discharging system 100 of the injection molding machine can be enhanced while the rotary tray 1222 is in butt joint with the feeding and discharging transmission assembly 133 or 132.

The first and second drive members 1225, 1226 may also be telescoping rods or other telescoping drive arrangements. In the present disclosure, the structures of the first driving member 1225 and the second driving member 1226 are not further limited.

It should be noted that, in addition to ensuring that the rotary tray 1222 is inclined in different directions with respect to the fixed tray 1221 to interface with the feeding and discharging transport assemblies 133 and 132, the first and second driving members 1225 and 1226 may also be disposed on the same side of the rotary tray 1222. Alternatively, the driving assembly 1224 may further include only the first driving member 1225 or the second driving member 1226, so as to control the telescopic extent of the telescopic end 1229 of the first driving member 1225 or the second driving member 1226, so as to enable the rotary tray 1222 to tilt in different directions relative to the fixed tray 1221, thereby implementing the docking of the rotary tray 1222 with the feeding conveying assembly 133 or the discharging conveying assembly 132.

The feeding and discharging system 100 of the injection molding machine has the advantages of being high in automation degree, reducing labor cost, greatly shortening the carrying path length of the carrying robot 140, reducing the feeding frequency, greatly reducing the management difficulty of plastic parts in feeding and discharging operations and improving the carrying efficiency of the plastic parts. And, the upper space of the workshop is fully utilized, so that the injection molding machine feeding and discharging system 100 has higher storage space utilization rate.
