Description

Technical Field

[0001] This invention relates to the field of automated packaging equipment technology, specifically to a counting and transfer system between a die-cutting machine and a packaging machine. Background Technology

[0002] Rotary die-cutting machines are core processing equipment in the adhesive products and electronic accessories industries. Through continuous rotary cutting, they complete raw material unwinding, lamination, precision punching, and waste removal, achieving high-speed product forming. They are commonly used for die-cutting products such as OCA optical adhesives, double-sided tapes, conductive foams, electronic accessories, and medical adhesive tapes. In the current production model, after the rotary die-cutting machine outputs products, they fall into a transfer container, are manually sorted, organized, and counted, and then transferred to the feeding channel of a pillow-type packaging machine for manual loading and packaging. The above production model has the following drawbacks: 1. Fragmented processes and discontinuous production: Die-cutting and packaging are two independent processes. Manual handling and material loading are time-consuming, and the cycle time is mismatched, resulting in limited overall production capacity. 2. Difficulty in ensuring product quality: Precision parts are small in size and require high cleanliness. Human contact can easily lead to fingerprints, dust, scratches, and adhesive contamination. Furthermore, they are prone to breakage and deformation during transportation, and material accumulation, jamming, and leakage can easily occur during loading, resulting in a high defect rate. 3. High labor costs and large errors: 2-3 operators are required for sorting and loading, resulting in high labor costs; and as labor time increases, manual counting is prone to errors such as multiple packages, fewer packages, and mixed materials, leading to poor consistency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a counting and transfer system between a die-cutting machine and a packaging machine, which addresses the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: A counting and transfer system between a die-cutting machine and a packaging machine, comprising: A conveyor belt, the input end of which is connected to the output end of the die-cutting machine; The discharge chute has its input end connected to the output end of the conveyor belt, and its output end is inclined downward. A counting sensor is disposed above the discharge chute, and the counting sensor is used to count the number of workpieces after they pass through the discharge chute. A stacking mechanism is used to receive workpieces discharged from the output end of the discharge chute and to stack the workpieces in the stacking bin. The transfer mechanism is used to grip all the workpieces in the stacking bin and transfer them to the channel at the input end of the packaging machine before releasing them.

[0005] Furthermore, the stacking mechanism includes a stacking bin and a first lifting mechanism. The stacking bin is located at the output end of the discharge chute, and the first lifting mechanism is located below the stacking bin. A support plate is provided on the lifting end of the first lifting mechanism. The support plate is located inside the stacking bin, and the first lifting mechanism is used to drive the support plate to move along the height direction of the stacking bin.

[0006] Furthermore, the bottom of the stacking bin is inclined toward the conveyor belt, and the angle between the height direction of the stacking bin and the output direction of the discharge chute is in the range of 160°~190°.

[0007] Furthermore, there are two stacking mechanisms, both of which are located on the moving end of the first translation mechanism. The first translation mechanism is used to drive the two stacking mechanisms to move horizontally so that the two stacking mechanisms can be exchanged between the stacking position and the transfer position. There are also two transfer mechanisms, which are used to clamp all the workpieces in the stacking compartments at the transfer positions of the two stacking compartments.

[0008] Furthermore, the transfer mechanism includes a second translation mechanism, a second lifting mechanism, a first rotation mechanism, and a gripping mechanism. The second translation mechanism is used to drive the gripping mechanism to move back and forth between the transfer position and the channel. The second lifting mechanism is used to drive the gripping mechanism to rise or fall. The first rotation mechanism is used to drive the gripping mechanism to rotate in a vertical plane. The gripping mechanism is used to drive the two grippers to move closer or further apart.

[0009] Furthermore, both sides of the stacking compartment are provided with clearance grooves that cooperate with the grippers, and the clearance grooves are connected to the top of the stacking compartment.

[0010] Furthermore, a first push cylinder is provided next to the stacking bin, and a aligning plate is provided on the push rod of the first push cylinder.

[0011] Furthermore, the conveyor belt is perpendicular to the channel, and the transfer mechanism also includes a second rotating mechanism, which is used to drive the clamping mechanism to rotate in the horizontal plane.

[0012] Furthermore, it also includes a rejection mechanism, which includes a lifting plate, a second push cylinder, and a waste hopper. A through hole is provided in the middle of the discharge chute. The second push cylinder is located below the discharge chute. The waste hopper is located on one side of the discharge chute. The top of the second push cylinder is inclined toward the waste hopper. The lifting plate is located on the push rod of the second push cylinder and is located in the through hole. The second push cylinder is used to push the lifting plate to extend obliquely out of the through hole or retract it into the through hole.

[0013] Furthermore, the conveyor belt is equipped with a positioning sensor, which is located above the output end of the conveyor belt. The positioning sensor is used to detect whether the workpiece has reached the output end of the conveyor belt.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: (1) This invention automates the counting and transfer process between the die-cutting machine and the packaging machine, realizing continuous operation from die-cutting to packaging, which can significantly improve production efficiency; (2) The present invention eliminates the manual transfer, sorting and loading steps, realizes no human contact, avoids human pollution, scratches and deformation, and is suitable for the high cleanliness requirements of production lines such as optical adhesives and precision electronic auxiliary materials; (3) The present invention has strong compatibility and can be adapted to mainstream rotary die-cutting machines and standard pillow packaging machines on the market. It does not require major modifications to existing equipment and is convenient for production line upgrades. (4) The present invention uses sensors to count and automatically count the number of packaged finished products, which meets the requirements of intelligent factory management.

[0020] Example 1 like Figure 1 and Figure 2 As shown, this embodiment discloses a counting and transfer system between a die-cutting machine and a packaging machine, including: a conveyor belt 1, a discharge chute 3, a counting sensor 4, a stacking mechanism 5, and a transfer mechanism 5. The conveyor belt 1, the discharge chute 3, the stacking mechanism 5, and the transfer mechanism 5 are arranged sequentially between the die-cutting machine 2 and the packaging machine 7 along the x-direction.

[0021] The conveyor belt 1 is arranged along the x-direction. The input end of the conveyor belt 1 is connected to the output end of the die-cutting machine 2. The workpieces processed by the die-cutting machine 2 are directly placed onto the conveyor belt 1, and the length direction of the workpieces placed on the conveyor belt 1 is parallel to the conveying direction of the conveyor belt 1.

[0022] A frame 33 is provided between the conveyor belt 1 and the transfer mechanism 6, and the discharge chute 3 and the stacking mechanism 5 are both installed on the frame 33. The input end of the discharge chute 3 is connected to the output end of the conveyor belt 1, and the end of the discharge chute 3 away from the conveyor belt 1 is inclined downward. The stacking mechanism 5 is used to receive the workpieces discharged from the output end of the discharge chute 3 and enables the workpieces to be stacked in the stacking bin 51.

[0023] After a certain number of workpieces are stacked in the stacking bin 51, the transfer mechanism 6 can grip all the workpieces in the stacking bin 51 and transfer them to the channel 71 at the input end of the packaging machine 7. The channel 71 includes a conveyor belt and limiting baffles on both sides of the conveyor belt. After the workpieces are transferred into the channel 71, the transfer mechanism 6 will release the workpieces, which will then move along the channel 71 towards the packaging station of the packaging machine 7 for subsequent packaging operations.

[0024] Die-cutting machine 2 is a rotary die-cutting machine, and packaging machine 7 is a pillow packaging machine.

[0025] Example 2 This embodiment is based on embodiment 1 and discloses the specific structure of the stacking mechanism 5.

[0026] like Figure 2 and Figure 3 As shown, a first translation mechanism 8 is provided on the frame 33, and the first translation mechanism 8 is located on the side of the discharge chute 3 away from the conveyor belt 1. The first translation mechanism 8 includes a first guide rod 81, a first moving frame 82 and a third push cylinder 83. Four first guide rods 81 are provided on the frame 33, and all four first guide rods 81 are arranged along the y-axis. The first moving frame 82 is slidably mounted on the first guide rods 81. The third push cylinder 83 is fixedly installed on the frame 33, and the push rod of the third push cylinder 83 is connected to the first moving frame 82.

[0027] like Figure 5 As shown, the stacking mechanism 5 includes a stacking compartment 51 and a first lifting mechanism 52. Both the stacking compartment 51 and the first lifting mechanism 52 are mounted on the first movable frame 82. The first lifting mechanism 52 is located below the stacking compartment 51. The stacking compartment 51 is provided with a support plate 53. The support plate 53 is fixedly connected to the lifting end of the first lifting mechanism 52. The first lifting mechanism 52 is used to drive the support plate 53 to move along the height direction of the stacking compartment 51.

[0028] like Figure 4As shown, the bottom of the stacking bin 51 is inclined toward the conveyor belt 1 to facilitate the workpiece sliding from the discharge chute 3 into the stacking bin 51. The angle α between the height direction of the stacking bin 51 and the output direction of the discharge chute 3 ranges from 160° to 190°, preferably 168°. The top of the stacking bin 51 and the side facing the discharge chute 3 are both open. The first lifting mechanism 52 includes a second guide rod 521, a first lead screw 522, a second movable frame 523, and a first motor 524. There are two second guide rods 521, both of which are fixedly mounted on the first movable frame 82. The first lead screw 522 is rotatably mounted on the first movable frame 82. Both the second guide rods 521 and the first lead screw 522 are parallel to the height direction of the stacking bin 51. The first motor 524 is fixedly mounted on the first movable frame 82, and its output end is connected to one end of the first lead screw 522. The second movable frame 523 is slidably mounted on the second guide rod 521. A nut that cooperates with the first lead screw 522 is provided on the second movable frame 523. A connecting frame 526 is fixedly mounted on the second movable frame 523. The top end of the connecting frame 526 extends into the stacking bin 51, and a bearing plate 53 is fixedly mounted on the top end of the connecting frame 526. The first motor 524 can drive the first lead screw 522 to rotate, thereby moving the support plate 53 within the stacking compartment 51 along the height direction of the stacking compartment 51.

[0029] The first moving frame 82 is equipped with two stacking mechanisms 5, which are symmetrical about the xz plane. The third push cylinder 83 is used to push the first moving frame 82 to move along the y-axis so that the two stacking bins 51 can be exchanged between the stacking position and the transfer position. There are also two sets of transfer mechanisms 6, which are used to clamp the stacked workpieces at the transfer positions of the two stacking bins 51.

[0030] Example 3 This embodiment is based on Embodiment 2 and discloses the specific structure of the transfer mechanism.

[0031] In this embodiment, channel 71 is arranged along the y-axis, and conveyor belt 1 is perpendicular to channel 71. Figure 6 and Figure 7As shown, the transfer mechanism 6 includes a second translation mechanism 61, a second lifting mechanism 62, a first rotating mechanism 63, a gripping mechanism 64, and a second rotating mechanism 65. The second translation mechanism 61 is arranged along the x-axis and is located above the frame 33 and the channel 71. The second lifting mechanism 62 is located on the moving end of the second translation mechanism 61. The second rotating mechanism 61 is located on the lifting end of the second lifting mechanism 62. The first rotating mechanism 63 is located on the rotating end of the second rotating mechanism 61. The gripping mechanism 64 is located on the rotating end of the first rotating mechanism 63. The gripping mechanism 64 is provided with two mutually symmetrical grippers 641. The second translation mechanism 61 is used to drive the clamping mechanism 64 to move along the x-axis direction, so that the clamping mechanism 64 reciprocates between the transfer position and the channel 71. The second lifting mechanism 62 is used to drive the clamping mechanism 64 to move along the z-axis direction. The second rotation mechanism 65 is used to drive the clamping mechanism 64 to rotate in the xz plane, so that the gripper 641 can tilt to adapt to the stacking bin 51. The first rotation mechanism 63 is used to drive the clamping mechanism 64 to rotate in the xy plane, so that the clamped workpiece can be aligned with the transmission direction of the channel 71.

[0032] like Figure 7 As shown, specifically, the second translation mechanism 61 includes a fixed frame 611, a first guide rail 612, a synchronous pulley 613, a third moving frame 614, and a second motor 615. The fixed frame 611 is fixedly mounted on the platform between the frame 33 and the channel 71. Two first guide rails 612 are arranged along the x-axis on the fixed frame 611. Synchronous pulleys 613 are rotatably mounted at both ends of the fixed frame 611, and the two synchronous pulleys 613 are connected by a synchronous belt 616. The second motor 615 is located at one end of the fixed frame 611 and is drively connected to one of the synchronous pulleys 613. The third moving frame 614 is slidably mounted on the first guide rail 612 and is fixedly connected to the synchronous belt 616. The second motor 615 drives the synchronous pulleys 613 and the synchronous belt 616 to rotate, thereby moving the third moving frame 614 along the first guide rail 612.

[0033] The second lifting mechanism 62 includes a second guide rail 621, a fourth movable frame 622, a second lead screw 623, and a third motor 624. Two second guide rails 621 arranged along the z-axis are fixedly mounted on the third movable frame 614. The second lead screw 623 is rotatably mounted on the third movable frame 614 and is arranged along the z-axis. The third motor 624 is located at the top of the third movable frame 614, and its output end is connected to the second lead screw 623. The fourth movable frame 622 is slidably mounted on the second guide rails 621, and a nut that mates with the second lead screw 623 is provided on the fourth movable frame 622. The third motor 624 drives the second lead screw 623 to rotate, thereby moving the fourth movable frame 622 along the second guide rails 621.

[0034] The second rotating mechanism 65 includes a rotating plate 651 and a fourth push cylinder 652. The top of the rotating plate 651 is hinged to the fourth movable frame 622, and the two ends of the fourth push cylinder 652 are respectively hinged to the fourth movable frame 622 and the rotating plate 651. The fourth push cylinder 652 is used to drive the rotating plate 651 to rotate in the xz plane.

[0035] The first rotating mechanism 63 includes a mounting frame 631, a rotating frame 632, and a rotating cylinder 633. The mounting frame 631 is fixedly mounted on the rotating plate 651, the rotating frame 642 is rotatably mounted on the mounting frame 631, and the rotating cylinder 633 is located on the top of the mounting frame 631. The output end of the rotating cylinder 633 is connected to the rotating frame 642 for transmission. The rotating cylinder 633 is used to drive the rotating frame 632 to rotate around its own axis. In the initial state, the axis of the rotating frame 632 is parallel to the z-axis.

[0036] The gripping mechanism 64 includes grippers 641 and finger cylinders 642. The finger cylinders 642 are fixedly mounted on the rotating frame 632, and each of the two moving ends of the finger cylinders 642 is equipped with a gripper 641. The finger cylinders 642 are used to drive the two grippers 641 to close or open, so as to grip or release stacked workpieces.

[0037] Preferably, the fourth movable frame 622 is provided with a limiting structure for limiting the rotation range of the rotating plate 651. The mounting frame 631 is provided with a limiting structure for limiting the rotation range of the rotating frame 632.

[0038] Both sides of the stacking chamber 51 are provided with clearance grooves 511 that cooperate with the grippers 641, and the clearance grooves 511 are connected to the top of the stacking chamber 51. The first moving frame 82 is provided with a first pushing cylinder 54, and the push rod of the first pushing cylinder 54 is provided with a slapping plate. The first pushing cylinder 54 is used to push the slapping plate through the clearance grooves 511 to slap the workpieces after a certain number of workpieces are stacked in the stacking chamber 51, so that the workpieces are stacked neatly.

[0039] The counting and transfer process in this embodiment includes: (1) After the raw material completes unwinding, lamination, precision rolling and waste removal in the die-cutting machine 2, the die-cutting machine 2 puts the processed workpiece onto the conveyor belt 1, and the conveyor belt 1 drives the workpiece to move towards the discharge slide 3. (2) The workpiece is discharged from the output end of the conveyor belt 1 into the discharge slide 3 and slides along the discharge slide 3 toward the stacking bin 51. When the workpiece passes the counting sensor 4, the counting sensor 4 detects the workpiece and sends an electrical signal to the control system. The control system determines that the number of workpieces in the stacking bin 51 is increased by one. (3) When the counting sensor 4 detects that the workpiece has passed through a preset time, the workpiece enters the stacking bin 51, and the first lifting mechanism 52 drives the bearing plate 53 to descend a preset distance; (As another implementation, the first lifting mechanism 52 descends after a preset number of workpieces enter the stacking bin 51, for example: after the control system determines that five workpieces have entered the stacking bin 51, the first lifting mechanism 52 drives the bearing plate 53 to descend a preset distance) (4) When the workpieces in the stacking bin 51 are stacked to a preset number, the first translation mechanism 8 drives the two stacking bins 51 to translate so that the full stacking bin 51 moves to the transfer position and the empty stacking bin 51 moves to the stacking position. (5) The second translation mechanism 61 drives the gripping mechanism 64 to move above the transfer position, the second lifting mechanism 62 drives the gripping mechanism 64 to descend, and the second rotating mechanism 65 drives the gripping mechanism 64 to rotate in the xz plane so that the tilt angle of the gripper 641 is consistent with the stacking bin 51. (6) After the two grippers 641 are aligned with the clearance slots 5111 on both sides of the stacking compartment 51, the finger cylinder 642 drives the two grippers 641 to move closer to each other to grip all the workpieces in the stacking compartment 51. Then the lifting mechanism 62 drives the gripping mechanism 64 to rise, and the second rotating mechanism 65 drives the gripping mechanism 64 to rotate in the xz plane so that the stacked workpieces are rotated to a vertical state. (7) The second translation mechanism 61 moves the workpiece to the top of the channel 71, and the first rotation mechanism 63 rotates the workpiece in the xy plane so that the length direction of the workpiece is parallel to the conveying direction of the channel 71. (8) The lifting mechanism 62 drives the workpiece to descend until the workpiece is separated from the channel 71 by a preset distance. Then, the finger cylinder 642 drives the two grippers 641 to move away from each other so as to release the stacked workpiece in the channel 71. The stacked workpiece moves along the channel 71. The packaging machine 7 receives the workpiece and automatically completes the film feeding, wrapping, heat sealing and cutting operations, and outputs the finished product with independent sealed packaging.

[0040] Repeat steps (1) to (8) to complete the counting, transfer and packaging of workpieces. It should be noted that steps (3) to (8) are performed alternately by two stacking mechanisms and transfer mechanisms to ensure the continuity of the process.

[0041] Example 4 This embodiment is based on any one of the embodiments 1 to 3, with the addition of a rejection mechanism 31.

[0042] like Figure 1 As shown, an inspection station 9 is set in the middle of the conveyor belt 1. The inspection station 9 uses visual inspection to determine whether there are defects in the appearance of the workpiece. Visual inspection technology is a conventional technique in this field and will not be described in detail here.

[0043] like Figure 3 and Figure 4 As shown, in order to discharge defective workpieces, a rejection mechanism 31 is provided in the middle of the discharge chute 3. The rejection mechanism 31 includes a lifting plate 311, a second push cylinder 312 and a waste hopper 313. A through hole 32 is provided in the middle of the discharge chute 3. The second push cylinder 312 and the waste hopper 313 are both installed on the frame 33. The waste hopper 313 is located on one side of the discharge chute 3. The top of the second push cylinder 312 is inclined toward the waste hopper 313. The lifting plate 311 is set on the push rod of the second push cylinder 312.

[0044] Preferably, the lifting plate 311 has a protrusion on the side away from the waste hopper 313. When the second push cylinder 312 drives the lifting plate 311 to push out obliquely, the protrusion is used to push the workpiece towards the waste hopper 313 so that the workpiece can pass over the stop edge of the discharge slide 3. The second push cylinder 312 is a three-axis cylinder.

[0045] Preferably, the output end of the conveyor belt 1 is also equipped with an ion fan to eliminate static electricity on the workpieces and prevent the workpieces from adsorbing each other.

[0046] A position sensor 11 is installed on the conveyor belt 1, and the position sensor 11 is located above the output end of the conveyor belt 11. The position sensor 11 is used to monitor whether the workpiece has reached the output end of the conveyor belt 11.

[0047] When a workpiece passes through inspection station 9, the camera on inspection station 9 captures an image of the workpiece and uploads it to the control system. The control system determines whether the workpiece image is qualified. If the workpiece is qualified, when the workpiece passes the positioning sensor 11, the control system determines that the qualified workpiece enters the discharge chute 3, the lifting plate 311 does not move, the workpiece can pass smoothly through the discharge chute 3, and the counting sensor 4 counts the qualified workpieces. After counting, the workpiece enters the stacking bin 51. If the workpiece is unqualified, when the workpiece passes the positioning sensor 11, the control system determines that the unqualified workpiece enters the discharge chute 3. After a preset time, the second push cylinder 312 drives the lifting plate 311 to extend obliquely out of the through hole 32, pushing the unqualified workpiece into the waste hopper 313. The counting sensor does not detect the unqualified workpiece entering the stacking bin 51 and does not count, thus completing the rejection action.
