Specific implementation manner
[0038] Example 1:
[0039] Please refer to Figures 1 - 4 , this embodiment is an automatic unpacking and palletizing equipment 100 for multi - stacked palletized packaging materials, which includes a conveyor line 1, palletizing lifting mechanisms 2 located on the left and right sides of the conveyor line 1, and a strapping cutting and recycling mechanism 3 located beside the conveyor line 1.
[0040] The palletizing lifting mechanism 2 includes a left lifting mechanism 21 and a right lifting mechanism 22 which are oppositely arranged on the left and right sides of the conveyor line 1. The left lifting mechanism 21 and the right lifting mechanism 22 have the same structure and both include a first motor 211, a first bracket 212 driven by the first motor 211 to move left and right, a second motor 213 fixed on the first bracket 212, a second bracket 214 driven by the second motor 213 to move up and down, and a support pallet 215 fixed on the second bracket 214. When the double - pallet glass comes, the two first brackets 212 approach each other, the support pallet 215 extends into the wooden pallet of the upper - layer stacking unit of the double - pallet glass, and then lifts upward to lift the upper - layer stacking unit, while the lower - layer stacking unit moves to the next station along with the conveyor line 1 to achieve palletizing.
[0041] In order to be applicable to various sizes of stacked palletized packaging materials, in this embodiment, a pair of support pallets 215 are provided, and a spacing adjustment module (not marked in the figure) for adjusting the spacing between the two support pallets 215 is also provided on the second bracket 214. The spacing adjustment module includes a third motor 216 fixed on the second bracket 214 and a lead screw 217 rotatably arranged on the second bracket 214 and driven by the third motor 216 to rotate. One of the support pallets 215 is slidably arranged back and forth on the second bracket 214, and a nut sleeve is arranged on the support pallet 215 and is connected in cooperation with the lead screw 217.
[0042] The strapping belt recycling mechanism 3 is mainly used to cut the outer periphery of multiple stacks of palletized packaging materials, and then pull out and recycle the strapping belts. The strapping belt cutting and recycling mechanism 3 includes a strapping belt recycling bin 31, a recycling and feeding module 32 located on one side of the strapping belt recycling bin 31 and used to recycle the strapping belts into the strapping belt recycling bin 31, a strapping belt cutting module 33 for cutting the strapping belts on the palletized packaging materials, and a clamping and pulling module 34 that passes the cut-off strapping belt ends through the recycling and feeding module 32 to straighten the strapping belts in the strapping belt recycling bin 31.
[0043] The strapping belt cutting module 33 and the strapping belt recycling bin 31 are arranged on opposite sides of the conveyor line 1, and the clamping and pulling module 34 is located above the strapping belt recycling bin 31. The strapping belt cutting module 33 includes a first XYZ transfer module 333, a first support plate 334 arranged at the movable end of the first XYZ transfer module 333, a first vision camera 335 fixed on the first support plate 334, and a first pneumatic scissor 336. The strapping belt cutting module 33 is used to cut the strapping belts on the outer periphery of multiple stacks of palletized packaging materials before the pallet separation lifting mechanism 2 performs the pallet separation operation, so that the pallet separation lifting mechanism 2 can split out multiple palletizing units. The position information of the strapping belts on the palletized packaging materials is obtained through the first vision camera 335, and then the three-dimensional spatial position of the first pneumatic scissor 336 is adjusted through the first XYZ transfer module 333 to align with the strapping belts, realizing the precise cutting of the strapping belts. By setting a vision camera in cooperation with a three-dimensional transfer module, the cutting requirements of strapping belts at various different positions can be met, improving the versatility of the production line.
[0044] The clamping and pulling module 34 is mainly used to pull the strapping belts cut from the outer periphery of multiple stacks of palletized packaging materials above the strapping belt recycling bin 31. It includes a second XYZ transfer module 344 arranged above the strapping belt recycling bin 31, a second support plate 345 arranged at the movable end of the second XYZ transfer module 344, and a strapping belt gripper 346 arranged on the second support plate 345.
[0045] The strapping belt cutting and recycling mechanism 3 in this embodiment is applicable to the situation where there is a large space on the workshop site. Multiple sets of strapping belt cutting modules 33 can be configured, and corresponding numbers of strapping belt recycling bins 31, clamping and pulling modules 34, and recycling and feeding modules 32 can be configured to complete the cutting and recycling of all the strapping belts on the palletized packaging materials at one time, with a higher cycle efficiency.
[0046] The recycling and feeding module 32 includes a first feeding roller 321 and a second feeding roller 322 which are arranged oppositely up and down, a first air cylinder 323 for driving the first feeding roller 321 to move up and down, and a second air cylinder 324 for driving the second feeding roller 322 to move up and down. A second vision camera 325 for obtaining the position of the peripheral packing tape of multiple stacked palletized packaging materials is further arranged on the input side of the first feeding roller 321 and the second feeding roller 322. The first air cylinder 323 and the second air cylinder 324 drive the two feeding rollers to switch states between the open state and the clamping state. In the open state, the clamping and pulling module 34 extends to clamp the cut packing tape, pulls it above the packing tape recycling bin 31, and then the feeding rollers switch to the clamping state. Under the rotational movement of the feeding rollers, the packing tape is conveyed towards the packing tape recycling bin 31, and finally all the packing tape is sent into the packing tape recycling bin 31 to achieve the recycling of the packing tape. One or both of the first feeding roller 321 and the second feeding roller 322 adopt electric rollers to realize rotational feeding.
[0047] When the two feeding rollers are in the open state, the second support plate 345 can drive the packing tape gripper 346 to pass through the gap space between the two feeding rollers for the clamping operation of the packing tape. Before the clamping and pulling module 34 clamps the cut packing tape, the second vision camera 325 first identifies the position of the packing tape, and then the second XYZ transfer module 344 drives the packing tape gripper 346 to move into place according to the position of the packing tape, so as to ensure that the packing tape gripper 346 can accurately grasp the packing tape.
[0048] Due to the long length of the packing tape, in order to save space and enable the effective and reliable recycling of the packing tape, a second pneumatic scissor 326 is arranged above the packing tape recycling bin 31 at the output side of the recycling and feeding module 32. The front and rear positions of the second pneumatic scissor 326 are adjustable and arranged on the slide rail 327.
[0049] The operation process of the automatic unpacking and palletizing equipment 100 for multiple stacked palletized packaging materials in this embodiment is as follows:
[0050] The multi-stack palletized packaging materials are moved into place through the conveyor line 1. The first vision camera 335 obtains the position information of the packing belt. The first XYZ transfer module 333 adjusts the position of the first pneumatic scissors 336 according to the position of the packing belt, and the first pneumatic scissors 336 is activated to cut the two outer vertical packing belts; then the second vision camera 325 identifies the position of the cut packing belt, and the second XYZ transfer module 344 adjusts the packing belt gripper 346 to extend in place according to the position of the cut packing belt, clamps the packing belt, and pulls it to within the range of the packing belt recycling bin 31; the first feeding roller 321 and the second feeding roller 322 are switched to the material clamping state, and under the rotational drive of the feeding rollers, the packing belt is conveyed towards the packing belt recycling bin 31. Every time a set length is conveyed, the second pneumatic scissors 326 is activated to cut the long packing belt into short strips until the packing belt is completely sent into the packing belt recycling bin 31, completing the automatic cutting, removal, and recycling of the peripheral packing belt of the multi-stack palletized packaging materials; the pallet separation lifting mechanism 2 lifts all the palletizing units above the second layer at the bottom, the conveyor line 1 conveys the bottommost palletizing unit to the next station, and then the pallet separation lifting mechanism 2 places all the upper palletizing units back onto the conveyor line 1; then it lifts all the new palletizing units above the second layer, thus completing the automatic depalletizing of the multi-stack palletized packaging materials.
[0051] Embodiment 2
[0052] Please refer to Figures 5 - 7 , this embodiment is an automatic unpacking and pallet separation device for multi-stack palletized packaging materials, which is basically the same as the structure in Embodiment 1, and the difference lies in: the structure of the packing belt cutting and recycling mechanism 3 is different. Specifically:
[0053] The packing belt cutting and recycling mechanism 3 includes a packing belt recycling bin 31, a recycling feeding module 32 located on one side of the packing belt recycling bin 31 and recycling the packing belt into the packing belt recycling bin 31, a packing belt cutting module 33 for cutting the packing belt on the stacked palletized packaging materials, and a clamping and pulling module 34 for passing the cut packing belt head through the recycling feeding module 32 and straightening the packing belt in the packing belt recycling bin 31.
[0054] In this embodiment, the packing belt cutting and recycling mechanism 3 is set as an integral mechanism along the conveyor line 1 with the left lifting mechanism 21 or the right lifting mechanism 22; the packing belt cutting and recycling mechanism 3 can be set to one, or two or more according to the size of the workshop space; when one packing belt cutting and recycling mechanism 3 is set, the conveyor line 1 conveys the multi-stack palletized packaging materials to successively pass through the packing belt cutting and recycling mechanism 3 to complete the cutting, extraction, and recycling of all the packing belts on the materials; if multiple packing belt cutting and recycling mechanisms 3 are set, after the conveyor line 1 conveys the multi-stack palletized packaging materials into place, all the packing belts on the multi-stack palletized packaging materials are cut, extracted, and recycled at one time through the multiple packing belt cutting and recycling mechanisms 3.
[0055] The packing belt cutting and recycling mechanism 3 further includes a third XYZ transfer module 35 located above the packing belt recycling bin 31 and a third support plate 36 provided at the movable end of the third XYZ transfer module 35. The packing belt cutting module 33 and the clamping and pulling module 34 are jointly arranged on the third support plate 36 and are driven by the third XYZ transfer module 35 to move their positions together.
[0056] The packing belt cutting module 33 includes a third cylinder 331 fixed on the third support plate 36 and a third pneumatic scissor 332 driven by the third cylinder 331 to move back and forth. The clamping and pulling module 34 includes a fixed clamping plate 341 and a fourth cylinder 342 fixed on the third support plate 36, and a packing belt hook 343 driven by the fourth cylinder 342 to hook the packing belt and press it against the fixed clamping plate 341. There are two packing belt hooks 343, and the two packing belt hooks 343 are arranged oppositely, with the hook directions opposite. One of them can be flexibly selected according to the position of the packing belt on the stacked and palletized packaging materials for hooking, pulling and clamping the packing belt. A third vision camera 37 for obtaining the position information of the packing belt on the stacked and palletized packaging materials is also arranged on the third support plate 36.
[0057] The packing belt cutting and recycling mechanism 3 in this embodiment is applicable to the scenario where the on-site space in the workshop is insufficient. In this embodiment, only one set of XYZ transfer module and one set of vision camera are configured to meet the requirements of packing belt cutting, head clamping and pulling, and packing belt position recognition, with lower costs.
[0058] The recycling and feeding module 32 includes a driving feeding roller 328, a driven feeding roller 329 that cooperates with the driving feeding roller 328 to clamp and convey the packing belt into the packing belt recycling bin, a fifth cylinder 3210 for driving the driven feeding roller 329 to move up and down, and a linear driving module 3211 for driving the driven feeding roller 329 to move horizontally between its avoidance position and its working position; the working position is above the driving feeding roller 328. When the driven feeding roller 329 is in the avoidance position, it is convenient for the clamping and pulling module 34 to pass by to straighten the cut packing belt head on the stacked and palletized packaging materials to the packing belt recycling bin 31. The fifth cylinder 3210 drives the driven feeding roller 329 to switch positions between the avoidance high position and the working low position. At the avoidance high position, the driven feeding roller 329 can move horizontally relative to the driving feeding roller 328. At the working low position, the driven feeding roller 329 and the driving feeding roller 328 clamp the packing belt and rotate for feeding.
[0059] The recycling and feeding module 32 further includes a fourth motor 3215 for driving the driving feeding roller 328 to rotate and feed.
[0060] A fourth support plate 3212 is provided at the movable end of the linear drive module 3211, and the fifth cylinder 3210 is fixedly arranged on the fourth support plate 3212; a packing belt cutting module 3216 is arranged on the fourth support plate 3212 at the output side of the driven feeding roller 329. The packing belt cutting module 3216 can adopt a conventional cutting mechanism in the prior art to cut the packing belt by upper and lower cutting knives and then recycle it, so as to solve the problem that it is inconvenient to recycle the too-long packing belt.
[0061] A limiting module 3213 for restricting the packing belt at a set position is arranged at the input side of the driving feeding roller 328. The limiting module 3213 includes a sixth cylinder 32131 and a pair of limiting claws 32132 driven by the sixth cylinder 32131 to perform opening or clamping actions. By closing the pair of limiting claws 32132, the packing belt is restricted within a set space range to prevent the packing belt from running around and affecting recycling.

[0063] The operation process of an automatic unpacking and palletizing device 100 for multi-stack palletized packaging materials in this embodiment is as follows: The conveyor line 1 conveys the multi-stack palletized packaging materials to the position of the packing belt cutting and recycling mechanism 3. The third vision camera 37 obtains the position information of the packing belt on the multi-stack palletized packaging materials. The packing belt claw 343 extends to hook the packing belt and presses it tightly against the fixed clamping plate 341. Then, the third pneumatic scissors 332 cut the packing belt; the packing belt claw 343 and the fixed clamping plate 341 clamp the packing belt head. Driven by the third XYZ transfer module 35, it is pulled above the packing belt recycling bin 31. The limiting module 3213 restricts the packing belt within a set space range, and the pressing module 3214 presses the packing belt; the linear drive module 3211 drives the driven feeding roller 329 and the packing belt cutting module 3216 to move above the driving feeding roller 328 together and presses the packing belt. At the same time, the packing belt claw 343 releases the packing belt head; driven by the fourth motor 3215, the driving feeding roller 328 and the driven feeding roller 329 convey the packing belt into the packing belt recycling bin 31. After conveying a set length, the packing belt cutting module 3216 cuts the packing belt, realizing the cutting, extraction, and cutting and recycling of the packing belt; after the packing belt is removed, the conveyor line 1 conveys the multi-stack palletized packaging materials to the palletizing lifting mechanism 2, or the palletizing lifting mechanism 2 directly completes the automatic depalletizing of the multi-stack palletized materials at the original position. The bottom stack of palletized materials is conveyed out by the conveyor line 1, and the palletizing lifting mechanism 2 then places the upper stack of palletized materials back on the conveyor line 1 for output.
[0064] For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
