[0087] like Figure 1The fully automated metal can lid packaging and palletizing production line shown in Figure 1 includes, in sequence, a docking conveyor belt, a flip-top rail assembly connected to the output end of the docking conveyor belt, an automatic counting and pushing lid assembly connected to the output end of the flip-top rail assembly, a pushing lid into a bag assembly connected to the output end of the automatic counting and pushing lid assembly, a transfer platform assembly, an automatic palletizing and wrapping film assembly, a packaged product gripping assembly located between the pushing lid into a bag assembly and the transfer platform assembly, and a palletizing mechanical gripper assembly located between the transfer platform assembly and the automatic palletizing and wrapping film assembly; wherein:

[0088] The function of the docking conveyor belt is to dock with the fully automatic metal can lid forming production line. Simply connect the input end of the docking conveyor belt to the output end of the fully automatic metal can lid forming production line conveyor belt. Once the metal can lid is formed, it will be automatically transferred to the docking conveyor belt.

[0089] The function of the flip-top rail assembly is as follows: Since the metal can lids are laid flat after coming out of the fully automatic metal can lid forming production line, and are also laid flat when conveyed to the docking conveyor belt, the subsequent processes before being fed into the packaging bag (automatic counting push-top assembly, push-top bag assembly) require the can lids to be erected. Therefore, the function of the flip-top rail assembly is to transform the flat metal can lids into an upright state.

[0090] The function of the automatic counting and push-cap assembly is to count the metal can caps after the metal can caps are adjusted by the flip-top rail assembly and before they reach the push-cap bagging assembly, so as to ensure that the number of can caps put into the bag is consistent in each bagging process.

[0091] The function of the push-cap-in-bag assembly is as follows: after the automatic counting push-cap assembly completes the predetermined count, and the subsequent can cap packaging bag is also prepared and the bag opening is also opened, the push-cap-in-bag assembly needs to push the counted metal can cap into the can cap packaging bag.

[0092] The function of the transfer platform component is as follows: after the counted metal can lids are pushed into the can lid packaging bag, the next process is to wait for the palletizing mechanical gripper component to grab the automatic palletizing wrapping component for palletizing. Since the mechanical action of the palletizing mechanical gripper component usually takes a certain amount of time, if the packaging bag with the can lid is always on the bag exit translation guide, it will affect the production efficiency of the previous process. Therefore, a transfer platform component needs to be set between the bag exit translation guide and the palletizing mechanical gripper component to ensure the fully automatic normal production operation of the packaging and palletizing production line and improve production efficiency.

[0093] The function of the palletizing mechanical gripper assembly is to first clamp the pallet from the pallet storage area onto the automatic palletizing and wrapping assembly, and then clamp the can lid packaging bag from the transfer platform onto the pallet, thereby realizing the automatic transfer of the position of the can lid packaging bag and the pallet.

[0094] The function of the automatic palletizing and wrapping assembly is to wrap the metal can lids that the palletizing mechanical gripper assembly has picked up on the palletizing plate in an S-shape to ensure the stability of the metal can lid stacking.

[0095] The function of the packaged finished product gripping device is to clamp the packaging bags with can lids on the bag delivery guide rail onto the transfer platform assembly for the palletizing machinery gripper assembly to grip.

[0096] In addition, a magnetic belt transfer assembly is installed at the input end of the docking conveyor belt. The purpose of this magnetic belt transfer assembly is to address the following: Before its implementation, if an unexpected situation occurred on the production line, the packaging and palletizing line would need to be shut down to prevent can lids from piling up at the packaging area, affecting work efficiency and potentially even requiring the can lid forming line to be stopped. This would result in high downtime costs and inconvenience for users. Therefore, the magnetic belt transfer assembly allows for the direct transfer of metal can lids from the docking conveyor line to the manual packaging line's transfer device in case of an emergency.

[0097] It should be noted that, to facilitate understanding and implementation of the fully automated packaging and palletizing production line of this application by those skilled in the art, the production line of this invention is further equipped with an easy-open lid packaging bag adsorption and translation component and a bag opening component in the lid-in-bag component. The easy-open lid paper bag adsorption and translation component is used to pick up the packaging bag from the bag groove and transport it to the bag opening component. The bag opening component is used to open the bag opening of the easy-open lid packaging bag, so that the lid-in-bag component can push the metal can lid into the packaging bag. The applicant has applied for patent protection for both of them, namely: easy-open lid paper bag adsorption and translation device, patent number: 202220377572.1; a paper bag opening device for easy-open lid packaging, patent number: 202321347538.0. Thus, a complete fully automated production line from the production terminal to the packaging and palletizing terminal is formed. The entire process is automated and requires no manual labor. After palletizing, only a forklift is needed to transport the pallet containing the can lid packaging bag away.

[0098] The above content describes the basic design principles and components of the production line of this invention. The embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0099] like Figure 3-5 As shown, the flip-top rail assembly 2 includes a flip-top assembly and an outlet conveyor belt 23. The outlet end of the docking conveyor belt 1 is connected to the flip-top assembly, so that the can lids 10 coming out of the can lid production line are directly conveyed to the inlet of the flip-top assembly. The outlet conveyor belt 23 is connected to the outlet of the flip-top assembly, so that the can lids 10 erected by the flip-top assembly can be conveyed to the automatic counting push-top assembly for counting through the outlet conveyor belt 23.

[0100] like Figure 5As shown, the flip-top assembly includes a rotary support component 24, a rotary shaft component 25, a rotary flip-top component 26, and a side adjustment component 27. The rotary support component 24 is a bearing support seat, and the rotary shaft component 25 is a rotating shaft connected to a drive mechanism, such as a drive motor (not shown in the figure). Both ends of the rotary shaft component 25 are fixed to the rotary support component 24, allowing the rotary shaft component 25 to rotate. The rotary flip-top component 26 includes a first magnet 260, a limiting strip 263, a first limiting sleeve 261, a second limiting sleeve 262, and two wheels 264. The wheel 264 is fixed on the rotating shaft component 25, so that the wheel 264 can rotate synchronously with the rotating shaft component 25. The distance between the two wheels 264 is adapted to the outer diameter of the can lid 10, so that the can lid 10 can be stuck between the two wheels 264. Thus, the rotation of the wheel 264 can drive the can lid 10 to rotate, so that the flat can lid 10 is in an upright state when it moves to the highest point of the movement trajectory of the wheel 264. Therefore, a lid pusher 330 can be set at the highest point of the movement trajectory of the wheel 264. When the can lid 10 rotates to this position, it is blocked by the lid pusher and accumulates. After a certain number are accumulated, it is conveyed to the next process.

[0101] Based on this, such as Figure 5 As shown, the first magnet 260 is an annular first magnet 260. The first magnet 260 is fixed on the rotating shaft component 25 and located between the two discs 264. Thus, when the can lid 10 is transported between the discs 264, the attraction of the first magnet 260 on the can lid 10 can be used to fix the can lid 10 to a certain extent.

[0102] More preferably, two first magnets 260 can be provided, respectively mounted on one side of the two discs 264.

[0103] Based on this, the first magnet 260 is fitted inside the first limiting sleeve 261 to prevent the first magnet 260 from directly contacting the can lid 10 and causing frictional damage to the can lid 10.

[0104] More preferably, the first limiting sleeve 261 is provided with an arc surface 2610. The function of the arc surface 2610 is to adapt to the shape of the can lid 10 so that the can lid 10 is more stably locked between the wheels 264.

[0105] like Figure 5As shown, a second limiting sleeve 262 is also provided between the two first limiting sleeves 261. A limiting strip 263 is provided on the working surface of the first limiting sleeve 261 and the working surface of the second limiting sleeve 262. The working surface is the contact surface between the first limiting sleeve 261, the second limiting sleeve 262 and the can lid 10. The limiting strip 263 can be made of elastic materials such as rubber. Its function is to prevent the can lid 10 from directly contacting the component and causing friction damage to the can lid 10.

[0106] like Figure 5 As shown, a side adjustment component 27 is also provided. The side adjustment component 27 is located on the side of one of the discs 264. It includes a fixing member 270 and a bolt 271. The fixing member 270 is also fixedly mounted on the rotary shaft component 25, so as to rotate synchronously with the disc 264. The fixing member 270 is provided with a screw hole. The bolt 271 is threaded through the screw hole and connected to the disc 264. That is to say, the disc 264 can be fixed on the rotary shaft component 25 and can move left and right.

[0107] Specifically, one disc 264 can be fixed to the rotating shaft component 25 by welding or other methods, while the other disc 264 is simply fitted onto the rotating shaft component 25 using a keyway or directly. Its position is fixed by bolts 271. Thus, the distance between the two discs 264 can be changed by rotating the bolts 271, allowing the device to adapt to can lids 10 of different sizes. It should be noted that bolt 271 is only one embodiment, but is not limited to it; any bolt capable of moving the disc 264 left and right on the rotating shaft component 25 is acceptable.

[0108] like Figure 2 , 6As shown in Figure 8, the automatic counting push-cover assembly 3 includes a push-cover bracket 31, a first swing assembly 32, and a push-cover assembly 33. The first swing assembly 32 includes a first swing cylinder 320, a first connecting rod 321, and a first swing shaft 322. The first swing shaft 322 is rotatably fixed on the push-cover bracket 31. One end of the first connecting rod 321 is fixed on the first swing shaft 322, and the other end is connected to the movable rod of the first swing cylinder 320, thereby controlling the direction of movement of the movable rod, the connection point between the movable rod and the first connecting rod 321, and the connection point between the first connecting rod 321 and the first swing shaft 322. The connection points of these three components are not located on a single line, thereby converting the linear motion of the movable rod into a certain angle rotation of the first swing shaft 322. As the first swing shaft 322 rotates within a certain angle, it can drive the push cover assembly 33 to swing. The push cover assembly 33 includes a push cover plate 330 and a mechanical rodless cylinder for driving the lateral displacement of the push cover plate 330. The mechanical rodless cylinder is fixed on the first swing shaft 322, so that as the first swing shaft 322 rotates, it can drive the push cover plate 330 to swing, and then move linearly with the action of the mechanical rodless cylinder.

[0109] Specifically, such as Figure 7 As shown, the mechanical rodless cylinder includes a cover-pushing cylinder body 331 and a cover-pushing drive block 332 that can move along the cover-pushing cylinder body 331. The cover-pushing cylinder body 331 is fixedly connected to the first swing shaft 322, and the cover-pushing plate 330 is driven by the cover-pushing drive block 332.

[0110] Specifically, such as Figure 7 As shown, a redundant stroke assembly 34 is also provided; the redundant stroke assembly 34 includes a redundant push-lid rod 341 guide block 40 and a redundant push-lid rod 341; the redundant push-lid rod 341 guide block 40 is fixed on the push-lid drive block 332, the redundant push-lid rod 341 is slidably fixed on the lid rod guide block, and the push-lid plate 330 is fixed on the redundant push-lid rod 341. Thus, when the push-lid plate 330 is inserted between the can lids 10, even if the push-lid plate 330 does not move laterally with the mechanical rodless cylinder, the push-lid plate... 330 can also move laterally under the pushing force of the subsequent can lid 10, that is, the redundant push rod 341 moves laterally on the guide block 40 of the redundant push rod 341. Thus, the mechanical rodless cylinder can be activated to push the can lid 10 to the next process only after a certain number of can lids 10 have accumulated. The redundant stroke assembly 34 can provide a limiting function for the can lids 10 on the conveyor belt, thereby providing support and preventing the can lids 10 from collapsing. In detail, without the redundant stroke assembly 34 for counting, such as... Figure 2As shown, the can lid 10 on the right side of the pusher 330 is the can lid 10 to be pushed to the next process, while the can lid 10 on the left side is the can lid 10 to be counted. When the pusher 330 is inserted into the can lid 10 and directly pushes it to the next process, the can lid 10 on the left side will directly lose the limiting and support of the pusher 330, causing the upright can lid 10 to collapse. Therefore, when the pusher 330 is moved to a certain position as the can lid 10 on the left side is continuously pushed, and then the mechanical rodless cylinder is activated to push the can lid 10 away, it means that the can lid 10 on the left side has accumulated a certain number, and under its own limiting effect, the risk of collapse can be basically avoided.

[0111] More specifically, such as Figure 7 As shown, the redundant stroke assembly 34 also includes a buffer guide block 342, which is fixedly connected to the redundant push cover rod 341, allowing the buffer guide block 342 and the redundant push cover rod 341 to move synchronously. A second magnet 343 is provided on one side of the buffer guide block 342, and the redundant push cover rod 341 guide block 40 is provided with a working surface (a metal surface that can be attracted by the second magnet 343) or a second magnet 343 that can cooperate with the second magnet 343. Through this arrangement, the buffer guide block... The position of the redundant push rod 341 guide block 40 when it is attracted together is the default position of the redundant push rod 341. When the redundant push rod 341 is pushed by the can lid 10, it will force the redundant push rod 341 guide block 40 to separate from the buffer guide block 342. After the separation reaches a certain extent, the mechanical rodless cylinder drives the redundant push rod 341 guide block 40 to move towards the buffer guide block 342, so that the two are attracted together again. Thus, when the mechanical rodless cylinder pushes the lid, it can drive the push plate 330 back to the initial position.

[0112] It should be noted that the second magnet 343 can be located on the buffer guide block 342 or on the redundant push cover rod 341 guide block 40.

[0113] More specifically, such as Figure 7 As shown, the redundant stroke assembly 34 is also provided with a buffer guide rod 344. The buffer guide rod 344 is fixed on the guide block 40 of the redundant push cover rod 341. The buffer guide block 342 is slidably disposed on the buffer guide rod 344, so that the buffer guide block 342 is restricted by the buffer guide rod 344 to move in a straight line, thereby improving the operational stability and avoiding failure.

[0114] It should be noted that the present invention does not describe in detail how the counting is implemented. In fact, it can be a component that calculates the moving position of the push cover plate 330 or a component that calculates the moving position of the buffer guide block 342. The specific component can be infrared sensor counting, photoelectric sensor counting, etc., and those skilled in the art can adjust it according to the actual situation.

[0115] like Figure 9-10 As shown, the can lid sliding assembly 4 includes a can lid slide 44 and a bag insertion bracket 41, a second swing assembly 42, and a bag insertion assembly 43 disposed on one side of the can lid slide 44. The second swing assembly 42 includes a second swing cylinder 420, a second connecting rod 421, and a second swing shaft 422. The second swing shaft 422 is rotatably fixed on the bag insertion bracket 41. Specifically, a bag insertion support seat is provided on the bag insertion bracket 410, and a bag insertion bearing 411 is provided inside the bag insertion support seat 410. One end of the second swing shaft 422 is fixed inside the bag insertion bearing 411, so that the second swing... Shaft 422 can rotate relative to bag insertion bracket 41; one end of the second connecting rod 421 is fixed on the second swing shaft 422, and the other end is connected to the movable rod of the second swing cylinder 420, so that the movement direction of the movable rod, the connection point between the movable rod and the second connecting rod 421, and the connection point between the second connecting rod 421 and the second swing shaft 422 are not on the same line, thereby realizing the transformation of the linear motion of the movable rod into a certain angle rotation of the second swing shaft 422. As the second swing shaft 422 rotates within a certain angle, it can drive the bag insertion assembly 43 to swing.

[0116] Specifically, such as Figure 10 As shown, the bag-feeding assembly 43 includes a mechanical rodless cylinder and a bag-feeding push rod 430 that is laterally displaced by the mechanical rodless cylinder. The mechanical rodless cylinder is fixed on the second swing shaft 422, allowing it to swing with the rotation of the second swing shaft 422. Thus, the action of the second swing cylinder 420 controls whether the bag-feeding push rod 430 enters the can lid slide 44. When the bag-feeding push rod 430 enters the can lid slide 44, the mechanical rodless cylinder drives the bag-feeding push rod 430 to move laterally, thereby pushing the can lid 10 in the can lid slide 44 into the can lid packaging bag 11. Furthermore, as... Figure 1 , 2 As shown, when the can lid 10 is pushed into the can lid packaging bag 11, the can lid packaging bag 11 containing the can lid is located on the bag exit translation guide rail 14. The bag exit translation guide rail 14 can be moved laterally by the drive chain 15, which makes it convenient for the finished product gripping component 5 to grip the can lid packaging bag 11.

[0117] More specifically, the mechanical rodless cylinder includes an infeed drive block 432 and an infeed cylinder body 431; the infeed cylinder body 431 is fixed on the second swing shaft 422, and the infeed drive block 432 is slidably disposed on the infeed cylinder body 431, that is, the infeed cylinder body 431 constitutes the guide rail of the infeed drive block 432. The advantage of using a mechanical rodless cylinder is that it has the advantages of large stroke, smooth operation and long service life.

[0118] More specifically, the working end of the bag-inserting push-cap rod 430 is fixed with a push-cap component 433, which is a component with a large surface area, thereby increasing the contact surface with the can lid 10 and ensuring a smooth push-cap process.

[0119] Preferably, the contact surface between the bag-inserting push rod 430 or the push-cap component 433 and the can lid 10 is made of rubber, or the entire part is molded from rubber, which can effectively prevent the surface of the can lid 10 from being scratched.

[0120] More specifically, the bag-inserting push-cap rod 430 is fixedly connected to the bag-inserting drive block 432 via two bag-inserting connectors 434; this arrangement helps to improve the connection strength.

[0121] More specifically, the bag insertion connector 434 is fixedly connected to the drive component via the bag insertion reinforcing plate 435; this arrangement can further improve the connection strength.

[0122] Specifically, the bottom of the second swing cylinder 420 is fixed on the fixing plate 427, which is fixed to the bag insertion bracket 41 by bolts; this arrangement helps to reduce the size of the equipment.

[0123] More specifically, the second connecting rod 421 has a first shaft hole 423 and a second shaft hole 424 at both ends, respectively. The second swing shaft 422 is fixed in the first shaft hole 423. A slot 425 is provided on the second connecting rod 421 parallel to the diameter direction of the first shaft hole 423. The slot 425 communicates with the first shaft hole 423. A screw hole is provided on the side of the slot 425 that passes through the second connecting rod 421. The second connecting rod 421 is locked by screwing a bolt into the screw hole, thereby locking the second swing shaft 422. This arrangement facilitates disassembly and maintenance.

[0124] More specifically, a bag-feed bearing is provided in the second shaft hole 424, and a movable rod shaft 426 is fixed in the inner ring of the bag-feed bearing. The movable rod of the second swing cylinder 420 is connected to the movable rod shaft 426.

[0125] like Figure 11-13 As shown, the packaged product gripping assembly 5 includes a transfer shaft 51 and a side gripping assembly 52 connected to the transfer shaft 51; the side gripping assembly 52 includes a side gripping cylinder 520 driven by the transfer shaft 51 and a side gripping component 521 driven by the side gripping cylinder 520; there are two side gripping components 521, which are arranged opposite to each other, and the opposite surfaces of the two are provided with mating surfaces 522 that are adapted to the shape of the can lid packaging bag 11.

[0126] In detail, the transfer shaft 51 is a drive component with lifting function, such as... Figure 1As shown, its lifting function is also achieved through the lifting chain 511. The lifting function is used to lower the side gripper 521 to a position where it can grip the can lid packaging bag 11. The top of the transfer shaft 51 is slidably set on the transfer guide rail 510. By moving the transfer shaft 51 on the transfer guide rail 510, the can lid packaging bag 11 gripped by the side gripper 52 is transferred to the transfer platform assembly 6.

[0127] To be more specific, such as Figure 1 , 11 As shown, the bottom of the transfer shaft 51 is fixed with a mounting plate 55, the side clamping cylinder 520 is fixed on the mounting plate 55, and there are two sets of side clamping components 52. The two sets of side clamping components 52 are arranged in a front-to-back manner. Compared with the method of setting only one set of side clamping components 52, that is, only one set of side clamping parts 521, this method can clamp the can lid packaging bag 11 more stably and firmly, avoiding the problem of poor stability due to the excessive length of one set of side clamping parts 521.

[0128] Since the opening of the can lid packaging bag 11 is usually quite long, and to prevent the can lid from falling out during the movement of the transfer shaft 51, it is necessary to seal the opening of the can lid packaging bag 11. Therefore, the present invention also provides a vertical folding bag assembly 53, which includes a vertical folding bag cylinder 530 that moves synchronously with the side clamping cylinder 520 and a vertical folding bag roller 534 driven by the vertical folding bag cylinder 530. The vertical folding bag roller 534 is located on the side of the side clamping assembly 52 located at the opening of the can lid packaging bag 11.

[0129] To be more specific, such as Figure 13 As shown, the vertical folding cylinder 530 is fixed on the mounting plate 55, thereby achieving synchronous movement with the side clamping cylinder 520. The vertical folding cylinder 530 is equipped with a vertical folding piston rod 531, which is connected to a vertical folding connecting block 532. The vertical folding connecting block 532 is fixed with a vertical folding support rod 533, and the vertical folding roller 534 is rotatably mounted on the vertical folding support rod 533. With this configuration, when the side clamping component 52 clamps the can lid packaging bag 11, the vertical folding cylinder 530 is activated, and the vertical folding piston rod 531 drives the vertical folding roller 534 downward, forcing the opening of the can lid packaging bag 11 to bend downward, thereby sealing the opening of the can lid packaging bag 11.

[0130] In order to bend the vertically folded portion of the can lid packaging bag 11 again to fit the bottom of the can lid packaging bag 11 for easy and neat stacking in the next process, the present invention also provides a horizontal folding assembly 54. The horizontal folding assembly 54 includes a horizontal folding cylinder 540 that moves synchronously with the side clamping cylinder 520 and a horizontal folding roller 543 driven by the horizontal folding cylinder 540. The horizontal folding roller 543 is located on the side of the side clamping assembly 52 located at the opening of the can lid packaging bag 11.

[0131] To be more specific, such as Figure 13 As shown, the horizontal folding cylinder 540 is fixed on the vertical folding connecting block 532, thereby achieving synchronous movement with the side clamping cylinder 520; the horizontal folding cylinder 540 is provided with a horizontal folding piston rod 541, which is connected to a horizontal folding support 542, and the horizontal folding roller 543 is rotatably mounted on the horizontal folding support 542; with this arrangement, when the vertical folding roller 534 forces the opening of the can lid packaging bag 11 to bend downwards, the horizontal folding roller 543 is just at the bottom of the can lid packaging bag 11. At this time, by using the horizontal folding cylinder 540 to drive the horizontal folding roller 543, the opening of the can lid packaging bag 11 can be bent again to fit the bottom of the can lid packaging bag 11.

[0132] Preferably, a horizontal folding connecting plate 544 is fixed on the outer shell of both the horizontal folding cylinder 540 and the vertical folding connecting block 532, and the horizontal folding connecting plate 544 is fixedly connected to the front of the horizontal folding reinforcing plate 545; thereby improving the connection strength.

[0133] It should be noted that the can lid packaging bag mentioned in this invention refers to a packaging bag that already contains can lids, and the packaging bag is cylindrical under the support of several can lids.

[0134] like Figure 14-16 As shown, the transfer platform component 6 includes a platform support 61, a stacking platform 62, a discharge connection component 63, and a discharge conveying power component 64. The stacking platform 62 is fixed on the platform support 61. The stacking platform 62 is provided with a stacking area 620, a connection area 621, and a track groove 622 connecting the stacking area 620 and the connection area 621. The track groove 622 passes through the stacking platform 62. The discharge connection component 63 is located between the stacking area 620 and the connection area 621 and is driven by the discharge conveying power component 64, so that the discharge connection component 63 can move between the stacking area 620 and the connection area 621. The discharge connection component 63 is provided with a cover bracket 630 with a lifting function. The cover bracket 630 is located in the track groove 622.

[0135] Specifically, the discharge connection assembly 63 includes a cover holder 630 and a connecting lifting cylinder 632 that drives the cover holder 630 to rise and fall. The cover holder 630 is fixed on the piston rod of the connecting lifting cylinder 632, thereby enabling the cover holder 630 to rise and fall.

[0136] More specifically, the track groove 622 is provided with three grooves, and each track groove 622 is provided with a cover holder 630; the cover holders 630 are connected by a connecting plate 631, and the piston rod of the connecting lifting cylinder 632 is fixed on the connecting plate 631; thereby, the conveying stability of the can lid packaging bag can be greatly improved.

[0137] Specifically, the discharge conveying power assembly 64 adopts a mechanical rodless cylinder. More specifically, the discharge conveying power assembly 64 consists of a discharge conveying cylinder body 640 and a discharge conveying drive component 641. The discharge conveying drive component 641 is slidably mounted on the discharge conveying cylinder body 640, which forms the track of the discharge conveying drive component 641. The discharge conveying cylinder body 640 is located below the stacking platform 62, and the conveying direction connects the stacking area 620 and the connecting area 621. The connecting lifting cylinder 632 is fixed on the discharge conveying drive component 641. Thus, by moving the discharge conveying drive component 641 on the discharge conveying cylinder body 640, the connecting lifting cylinder 632 can be moved between the stacking area 620 and the connecting area 621.

[0138] Preferably, the platform support 61 is provided with a module area 65, the stacking platform 62 is provided on the module area 65, the discharge connection component 63 and the discharge conveying power component 64 are provided in the module area 65, and a hinge door 66 is provided on one side of the module area 65. With this arrangement, the operation of the discharge connection component 63 and the discharge conveying power component 64 can be directly observed by opening the hinge door 66, which also facilitates maintenance.

[0139] More preferably, the card cover holder 630 is semi-hexagonal, but not limited to this, it can also be arc-shaped. Its main function is to improve the stability of the can lid packaging bag and prevent the can lid packaging bag from being damaged during movement.

[0140] More preferably, the stacking area 620 is provided with a plurality of limiting strips 623, and the stacking position of the can cap packaging bag is formed between every two limiting strips 623; with such a setting, multiple fixed stacking points of can cap packaging bags can be formed on the stacking area 620, which can facilitate the gripping and positioning of the palletizing robot.

[0141] Specifically, the stacking area 620 is provided with a dividing strip 624, which can divide the stacking area 620 into an automatic stacking area 620 and a manual stacking area 620. When the automatic stacking area 620 is almost full, some can cap packaging bags can be manually placed into the manual stacking area 620 to avoid affecting the previous process.

[0142] During operation, the can cap holder 630 is in the default position within the connecting area 621. First, the easy-open can cap packaging bag 11 on the bag-exit translation guide 14 is gripped onto the can cap holder 630 by the easy-open can cap packaging finished product gripping component. At this time, the discharge conveying power component 64 drives the can cap holder 630 to move to the stacking area 620. Then, the discharge connecting cylinder drives the can cap holder 630 to descend, placing the can cap packaging bag 11 between the limit strips 623. The can cap holder 630 continues to descend, disengaging from the can cap packaging bag 11. The discharge conveying power component 64 then returns the can cap holder 630 to its default position for the next conveying cycle. Meanwhile, the can cap packaging bag 11 in the stacking area 620 can be clamped by the palletizing machine gripper component 7 and placed in the palletizing area for palletizing (e.g., ...). Figure 1 (As shown).

[0143] like Figure 17-21 As shown, the palletizing machine gripper assembly 7 includes a connecting seat 71, a pallet gripping assembly 72 connected to the connecting seat 71, and a can lid gripping assembly 73. The can lid gripping assembly 73 includes a fixed clamping rod 730, a movable clamping rod 731, and a gripper cylinder 732. The fixed clamping rod 730 and the movable clamping rod 731 are arranged opposite to each other, so that the fixed clamping rod 730 and the movable clamping rod 731 form a gripping range for the can lid. The movable clamping rod 731 is connected to the piston rod of the gripper cylinder 732, and the gripper cylinder 732 is connected to the connecting seat 71. The pallet gripping assembly 72 includes a gripper cylinder 720 and two grippers 721 arranged opposite to each other. One end of the gripper 721 is rotatably connected to the connecting seat 71, and the piston rod of the gripper cylinder 720 is fixed on the gripper 721. The connection point between the piston rod and the gripper 721 is not at the same position as the center of the rotation trajectory of the gripper 721.

[0144] The above describes the basic design principle of the palletizing machine gripper assembly 7 of the present invention. It can be seen that by cooperating with a set of fixed clamping rods 730 and movable clamping rods 731, and using the gripper cylinder 732 to move the movable clamping rod 731 to reduce the distance between the movable clamping rod 731 and the fixed clamping rod 730, a can lid packaging bag 11 can be gripped. Furthermore, by using the gripper cylinder 720 to retract the two grippers 721, a pallet can be clamped. It should be noted that although the gripper 721 structure shown in the accompanying drawings cannot clamp a pallet, those skilled in the art can adjust the structure and shape of the gripper 721 according to the pallet structure. The present invention only provides a palletizing machine gripper technology that can grip both pallets 13 and can lid packaging bags 11. Those skilled in the art can make adaptive adjustments to the number of fixed clamping rods 730 and movable clamping rods 731, the specific shape of the grippers 721, and the connection structure between the gripper cylinder 720 and the grippers 721 based on the technical principles of the present invention.

[0145] To facilitate those skilled in the art in implementing the technical concept of the palletizing machinery gripper assembly 7 of the present invention, the applicant provides a preferred embodiment, as follows:

[0146] Specifically, the pallet gripping assembly 72 further includes two linkage rods 722, which are rotatably fixed to the connecting seat 71 via bearing seats 723; the grippers 721 are fixed to the linkage rods 722; with this arrangement, four grippers 721 can be fixed by the two linkage rods 722, and the four grippers 721 can be used to fix and grip the four points of the pallet, thereby improving gripping stability.

[0147] More specifically, the can lid gripping assembly 73 is provided with two or more sets; such as Figure 23 , 24 As shown in Figures 26 and 27, this embodiment has 4 sets, so each mechanical gripper action can grab four can lid packaging bags 11 for stacking, increasing production efficiency by 4 times.

[0148] Since this embodiment is provided with 4 sets of can lid gripping components 73, and in order to improve the adaptability of the present invention, that is, to grip can lids of different sizes, a component that can adjust the spacing between adjacent can lid gripping components 73 is needed. Therefore, the present invention also provides a gripping spacing adjustment component 74 and a spacing adjustment cylinder 75. The gripping spacing adjustment component 74 includes a sliding block 740 and a connecting plate 742; the spacing adjustment cylinder 75 is fixed on a connecting seat 71, the bottom of the connecting seat 71 is provided on a slide rail 741, the sliding block 740 slides with the slide rail 741, the piston rod of the spacing adjustment cylinder 75 is connected to the sliding block 740, the sliding block 740 is connected to the connecting plate 742, the fixing clamp 730 is fixed to one end of the connecting plate 742, and the gripper cylinder 732 is fixed to the other end of the connecting plate 742.

[0149] More specifically, the gripping and adjusting assembly 74 is provided in three sets. The sliding block 740 of the outermost gripping and adjusting assembly 74 is connected to the piston rod of the adjusting cylinder 75. Adjacent gripping and adjusting assemblies 74 are connected to each other through adjusting screws 743. With this arrangement, when dealing with can lids of different sizes, the spacing between adjacent sliding blocks 740 is first adjusted by adjusting screws 743, and then the adjusting cylinder 75 is activated to drive the outermost sliding block 740 to move, thereby making fine adjustments so that the fixed clamping rod 730 and the movable clamping rod 731 of each can lid gripping assembly 73 are in the optimal position. This enables gripping and stacking of can lids of different sizes, improving the applicability of the invention.

[0150] More specifically, such as Figure 18 , 19 As shown, the number of gripping and adjusting components 74 is less than one set of can lid gripping components 73, so that at least one set of can lid gripping components 73 is connected to the connecting seat 71 without being adjusted in position by the gripping and adjusting components 74. In detail, if there are 4 sets of can lid gripping components 73, then there are 3 sets of gripping and adjusting components 74. If there is only 1 set of can lid gripping components 73, then there is no need for gripping and adjusting components 74. Through this setting, there is always one set of gripping and adjusting components 74 directly connected to the connecting seat 71, which can serve as a base point to facilitate the spacing adjustment of multiple sets of can lid gripping components 73.

[0151] Specifically, the gripper 721 is connected to a pallet hook 724 that can hook onto the pallet; as mentioned above, the present invention does not limit the structural form of the gripper 721, as long as it can grasp the pallet when the two grippers 721 are joined together. The pallet hook 724 is only a technical solution for the four grippers 721 in this embodiment, which is a relatively simple and low-cost implementation.

[0152] Specifically, the can lid gripping assembly 73 is further provided with an electromagnet 733 for adsorbing the can lid between the fixed clamping rod 730 and the movable clamping rod 731. Specifically, the electromagnet 733 is fixed to the bottom of the connecting plate 742, thereby being located above the fixed clamping rod 730 and the movable clamping rod 731, so that the magnetic force range of the electromagnet 733 is within the clamping range of the fixed clamping rod 730 and the movable clamping rod 731. With this arrangement, after the fixed clamping rod 730 and the movable clamping rod 731 clamp the can lid packaging bag 11, the magnetic force of the electromagnet 733 can be used to attract the can lid inside the can lid packaging bag, thereby improving the stability and reliability of the invention during the can lid transfer process.

[0153] More specifically, such as Figure 19 As shown, each connecting plate 742 has four electromagnets.

[0154] It should be noted that the main design principle of this invention lies in providing a palletizing mechanical gripper device that can grip both pallets and can lid packaging bags 11. The technical solutions for gripping pallets and can lid packaging bags 11 have been fully disclosed above. Moving the mechanical gripper device to the required position can be achieved through a multi-axis linkage manipulator structure, such as fixing the connecting seat 71 of the palletizing mechanical gripper to a multi-axis linkage structure (e.g.,...). Figure 1 As shown in the figure, it will not be described in detail in this invention.

[0155] like Figure 22-28 As shown, the automatic palletizing and wrapping film assembly 8 includes a pallet platform 81, a Z-axis support 82 disposed on one side of the pallet platform 81, an X-axis support 83 that can move up and down along the Z-axis support 82, and a wrapping film assembly 84 that can move laterally along the X-axis support 83. The wrapping film assembly 84 includes a film tube support 841 and a film tube 840 that is rotatably fixed on the film tube support 841. The film tube support 841 is movably disposed on the X-axis support 83. The pallet platform 81 is disposed on one side of the X-axis support 83 and is located within the travel range of the film tube support 841, so that when the film tube support 841 moves laterally on the X-axis support 83, the film tube 840 will pass through the pallet platform 81.

[0156] Specifically, such as Figure 1 , 22 As shown in Figure 23, the Z-axis bracket 82 is a main support frame 820. A Z-axis guide rail 821 and a Z-axis screw 822 are provided on the main support frame 820. A Z-axis motor 823 is connected to the bottom of the Z-axis screw 822. The X-axis bracket 83 is slidably mounted on the Z-axis guide rail 821 and cooperates with the Z-axis screw 822 through a screw seat 836. Thus, the rotation of the Z-axis motor 823 drives the X-axis bracket 83 to move up and down on the Z-axis bracket 82.

[0157] Specifically, the X-axis support 83 is divided into two parts, as follows: Figure 22 The distribution shown is divided into a left X-axis support 830 and a right X-axis support 831, and two Z-axis guide rails 821 are provided. The left X-axis support 830 and the right X-axis support 831 are respectively mounted on one Z-axis guide rail 821. The left X-axis support 830 and the right X-axis support 831 are fixedly connected by a film-wrapping connecting plate 835, and the screw seat 836 is fixed on the film-wrapping connecting plate 835. Both the left X-axis support 830 and the right X-axis support 831 are provided with X-axis guide rails 832.

[0158] Specifically, such as Figure 23As shown, the membrane tube support 841 is also divided into a left membrane tube support 8410 and a right membrane tube support 8411. The left membrane tube support 8410 and the right membrane tube support 8411 are slidably mounted on the X-axis guide rails 832 of the left X-axis support 830 and the right X-axis support 831, respectively. The two ends of the membrane tube 840 are rotatably mounted on the left membrane tube support 8410 and the right membrane tube support 8411, thereby allowing the membrane tube 840 to rotate relative to the membrane tube support 841, thus enabling the membrane tube 840 to have an unwinding function.

[0159] More specifically, such as Figure 23 As shown, a transmission belt 833 is provided inside the X-axis guide rail 832. The transmission belt 833 is driven by the X-axis motor 834. Belt drive components are provided at the bottom of the left membrane tube support 8410 and the right membrane tube support 8411. The belt drive components are mounted on the transmission belt 833, thereby driving the transmission belt 833 to rotate via the X-axis motor 834, which in turn drives the left membrane tube support 8410 and the right membrane tube support 8411 to move laterally within the X-axis guide rail 832.

[0160] More specifically, a membrane tube fixing shaft 842 is provided between the left support 8410 and the right support 8411 of the membrane tube, and the membrane tube 840 is fitted on the membrane tube fixing shaft 842 with clearance.

[0161] More specifically, such as Figure 24 As shown, a limiting flange 8421 is provided on the membrane tube fixing shaft 842. The limiting flange 8421 consists of two parts, which are fixed to the membrane tube fixing shaft 842 by bolts. With this setting, the limiting flange 8421 can limit and fix both ends of the membrane tube 840, preventing the membrane tube 840 from shifting laterally and also preventing the membrane tube 840 from rotating.

[0162] More specifically, such as Figure 24 As shown, the top of the left support 8410 and the right support 8411 of the membrane tube are provided with U-shaped positioning members 843. The two side walls of the U-shaped positioning members 843 are provided with first through holes 8430. The end of the membrane tube fixing shaft 842 is provided with a through hole corresponding to the first through hole 8430, so that the membrane tube fixing shaft 842 can be fixed on the membrane tube support 841 by inserting a pin or plug into the through hole and the first through hole 8430. With this setting, the membrane tube 840 can be easily disassembled, that is, when the membrane on the membrane tube 840 is used up, it can be easily replaced.

[0163] Specifically, such as Figure 24As shown, the top of the left membrane tube support 8410 and the right membrane tube support 8411 are provided with a plane bearing 844. The U-shaped positioning member 843 is set on the plane bearing 844, and the bottom of the U-shaped positioning member 843 is provided with a second through hole that communicates with the center hole of the plane bearing 844. The top of the left membrane tube support 8410 and the right membrane tube support 8411 are provided with bolt holes. Thus, bolts can pass through the second through hole and the center hole of the plane bearing 844 and engage with the bolt holes on the top of the membrane tube support 841, thereby allowing the U-shaped positioning member 843 to rotate relative to the membrane tube support 841. With this setting, when both ends of the membrane tube fixing shaft 842 are placed on the U-shaped positioning member 843, the rotation function of the U-shaped positioning member 843 can be used for self-alignment. By using the concentricity of the two sides, the membrane tube 840 can be automatically aligned.

[0164] Specifically, such as Figure 22 , 24 As shown, a cutter assembly 85 is also provided; it includes a flywheel blade 853, a cutter cylinder 855 that drives the flywheel blade 853 to move laterally, and a cutter motor 854 that drives the cutter to rotate; more specifically, the cutter assembly 85 includes a cutter housing 850, a flywheel blade 853, a cutter motor 854, a cutter cylinder 855, a cutter support 856, a cutter sliding block 857, and a cutter transverse guide rail 858; the cutter transverse guide rail 858 is fixed on the left support 8410 and the right support 8411 of the membrane cylinder, so that the cutter transverse guide rail 858 moves along the X-axis and Z-axis with the membrane cylinder support 841; the cutter sliding block 857 is slidably mounted on the cutter transverse guide rail 858 and interacts with the flywheel blade 853 to rotate laterally. The cutting mechanism is connected, with the cutter housing 850 fixed on the cutter sliding block 857. The flywheel blade 853, cutter cylinder 855, and cutter support 856 are all located inside the housing. The flywheel blade 853 is connected to the cutter motor 854, which is fixed on the cutter support. The cutter support 856 is connected to the piston rod of the cutter cylinder 855, allowing the cutter cylinder 855 to drive the cutter support 856 to move laterally. Both the cutter support 856 and the cutter housing 850 have slots for the blade edge of the flywheel blade 853 to pass through, allowing part of the flywheel blade 853 to extend out of the cutter housing 850 under the drive of the cutter cylinder 855, thereby cutting the film.

[0165] More specifically, such as Figure 24 As shown, a cutter sleeve rod 851 is provided inside the cutter housing 850, and a cutter sliding sleeve 852 is provided in the cutter support member 856 to cooperate with the cutter sleeve rod 851. The cutter sliding sleeve 852 is sleeved on the cutter sleeve rod 851, and the piston rod of the cutter cylinder 855 is fixed on the cutter support member 856. This can prevent the weight of the cutter support member 856 and other components from being entirely applied to the piston rod of the cutter cylinder 855, thereby reducing the wear and tear on the cutter cylinder 855.

[0166] Preferably, such as Figure 24 As shown, the transmission mechanism preferably uses a cable chain 859.

[0167] Specifically, such as Figure 26 , 28 As shown, two guide rollers 845 are provided on the film tube support 841. Both guide rollers 845 are rotatably mounted on the film tube support 841 and located below the film tube 840. Specifically, the two ends of the guide rollers 845 are rotatably fixed to the left support 8410 and the right support 8411 of the film tube, respectively, so that the guide rollers 845 move together with the film tube support 841. With this arrangement, the packaging film 12 of the film tube 840 passes between the two guide rollers 845 and is placed on the pallet 13. During the movement of the film winding assembly 84, the guide rollers 845 can be used to place the packaging film 12 flat on the can lid packaging bag 11. In particular, through the accurate design of the control program, the rising height of the X-axis support 83 is controlled so that the bottom surface of the guide rollers 845 is always one layer of packaging film 12 away from the top layer of can lid packaging bag 11. This can better ensure that the packaging film 12 is fully wound on each layer of can lid packaging bag 11.

[0168] More specifically, such as Figure 27 As shown, the left support 8410 and right support 8411 of the film tube are provided with transverse displacement grooves 8412. The end of a guide roller 845 is located in the transverse displacement groove 8412. Guide roller cylinders 846 are provided on the left support 8410 and right support 8411 of the film tube. The piston rod of the guide roller cylinder 846 is connected to the guide roller 845 located in the transverse displacement groove 8412, so that the guide roller cylinder 846 can drive the guide roller 845 to move in the transverse displacement groove 8412. This allows the distance between the two guide rollers 845 to be adjusted, thus facilitating the initial manual pulling of the packaging film 12 between the two guide rollers 845.

[0169] Specifically, such as Figure 28 As shown, a tension roller 847 is also provided between the left support 8410 and the right support 8411 of the film tube. The position of the tension roller 847 is such that it can change the movement trajectory of the unwound film in its natural state, thereby controlling the tension of the unwound film to a certain extent.

[0170] More specifically, the tensioning roller 847 is provided with three rollers.

[0171] Specifically, such as Figure 22As shown, the pallet platform 81 includes a platform support 810 and a support platform. The support platform is fixed on the platform support 810, thus forming the most basic function of the pallet platform 81, which has the most basic function of supporting the pallet 13. As an optimized solution, a pallet conveyor belt 811 (the pallet conveyor belt 811 is equivalent to the support platform) is set on the platform support 810. This allows the pallet conveyor belt 811 to connect with subsequent processes. After the pallet is stacked, the pallet 13 can be directly transported out using the pallet conveyor belt 811.

[0172] More specifically, at least two pallet conveyor belts 811 are provided, and the spacing between the two pallet conveyor belts 811 is adapted to the width of the pallet 13, so that the two pallet conveyor belts 811 are located on both sides of the width of the pallet 13.

[0173] As a preferred option, such as Figure 22 As shown, since the bottom of the pallet 13 is provided with three grounding plates 813, the pallet conveyor belts 811 should also be provided with three. That is to say, the number of pallet conveyor belts 811 is based on the increase of the structure of the pallet 13. When the bottom of the pallet 13 is flat, only one pallet conveyor belt 811 is required, as long as it can transport the stacked pallet 13 out of the device.

[0174] Specifically, such as Figure 22 , 25 As shown, a pallet alignment component 86 is also provided; the pallet alignment component 86 includes two sets of horizontal alignment modules 860 and two sets of vertical alignment modules 861; the two sets of horizontal alignment modules 860 are respectively set on both sides of the pallet 13 in the horizontal direction for aligning the pallet 13 in the horizontal direction, and the two sets of vertical alignment modules 861 are set on both sides of the pallet 13 in the vertical direction for aligning the pallet 13 in the vertical direction. Thus, the pallet alignment component 86 is used to align the pallet 13 on the pallet platform 81 so that the pallet 13 is in the optimal position for the palletizing process of the palletizing machine gripper.

[0175] More specifically, such as Figure 25 As shown, the lateral alignment module 860 includes a lateral alignment connecting plate 8600, a lateral alignment cylinder 8603, and a lateral alignment push plate 8604. The two ends of the lateral alignment connecting plate 8600 are fixed to the left X-axis support 830 and the right X-axis support 831, respectively. The lateral alignment cylinder 8603 is mounted on the lateral alignment connecting plate 8600, and the lateral alignment push plate 8604 is fixed to the piston rod of the lateral alignment cylinder 8603. Thus, when the pallet 13 is placed on the pallet platform 81, the X-axis support 83 is first raised so that the lateral alignment push plate 8604 is at the same horizontal position as the pallet 13. Then, driven by the lateral alignment cylinder 8603, the lateral position of the pallet 13 is aligned by the push of the two lateral alignment push plates 8604.

[0176] More specifically, such as Figure 25 As shown, the transverse alignment connecting plate 8600 is provided with two transverse alignment sliding sleeves 8601, and the transverse alignment push plate 8604 is provided with a transverse alignment sliding rod 8602, which is sleeved inside the transverse alignment sliding sleeves 8601. This arrangement can improve the stability of the transverse alignment push plate 8604 and prevent the weight of the transverse alignment push plate 8604 from acting only on the piston rod of the transverse alignment cylinder 8603.

[0177] Specifically, such as Figure 25 As shown, the longitudinal alignment module 861 includes a longitudinal alignment cylinder 8610 and a longitudinal alignment push plate 8611. As an optimal solution, the longitudinal alignment cylinder 8610 is fixed on the transverse alignment connecting plate 8600, so that the longitudinal alignment cylinder 8610 rises and falls synchronously with the X-axis bracket 83; the longitudinal alignment push plate 8611 is fixed on the piston rod of the longitudinal alignment cylinder 8610, so that the action of the piston rod of the longitudinal alignment cylinder 8610 forces the longitudinal alignment push plate 8611 to push the two sides of the pallet 13 longitudinally.

[0178] It should be noted that fixing the longitudinal alignment cylinder 8610 to the transverse alignment connecting plate 8600 is only the best embodiment of the automatic film wrapping and palletizing assembly of the present invention, but it is not limited to this. In fact, it can also be directly fixed to the left X-axis bracket 830 and the right X-axis bracket 831.

[0179] More specifically, such as Figure 25 As shown, the longitudinal alignment module 861 further includes a longitudinal alignment support frame 8612, a longitudinal alignment sliding sleeve 8613, and a longitudinal alignment sliding rod 8614. The longitudinal alignment support frame 8612 is fixed on the transverse alignment connecting plate 8600. One end of the longitudinal alignment sliding rod 8614 is fixed on the longitudinal alignment support member, and the other end is fixed on the left X-axis bracket 830 (the longitudinal alignment sliding rod 8614 of the other longitudinal alignment module 861 is fixed on the right X-axis bracket 831). The longitudinal alignment sliding sleeve 8613 is fixed on the longitudinal alignment push plate 8611, and the longitudinal alignment sliding sleeve 8613 is fitted onto the longitudinal alignment sliding rod 8614. Thus, the weight of the longitudinal alignment push plate 8611 can be supported by the longitudinal alignment sliding rod 8614 and the longitudinal alignment support frame 8612, improving the stability and service life of the parts.

[0180] Working principle of automatic palletizing and wrapping film assembly:

[0181] Specifically, such as Figure 1 , 22As shown, the pallet platform 81 is positioned between the left X-axis support 830 and the right X-axis support 831. The function of the pallet platform 81 is to place the pallet 13 gripped by the palletizing machine gripper assembly 7. When the pallet 13 is placed on the pallet platform 81, the X-axis support 83 rises, making the two lateral alignment push plates 8604 and the two longitudinal alignment push plates 8611 of the pallet alignment assembly 86 level with the pallet 13. Then, the alignment push plates are moved by the action of the lateral alignment cylinder 8603 and the longitudinal alignment cylinder 8610, thereby aligning the pallet 13 to its default position to facilitate palletizing by the palletizing machine gripper. Afterward, the palletizing machine gripper assembly can then grip the can lid package on the transfer platform. The bag 11 is placed on the pallet 13. Driven by the X-axis motor 834, the film cylinder 840 moves laterally above the can lid packaging bag 11. During the lateral movement of the film cylinder 840, it is unwound due to its rotation, thus placing the film on the can lid packaging bag 11. Then, the palletizing machine gripper assembly continues to grip the can lid packaging bag 11 for palletizing. When it reaches the second layer of can lid packaging bag 11, the X-axis support 83 is raised to a certain height by the Z-axis motor 823. The action of the X-axis motor 834 forms the second layer of wrapping film. Thus, by using the repeated coordinated action of the X-axis support 83 and the Z-axis support 82, automatic wrapping film packaging and palletizing can be achieved.

[0182] The working principle of the automatic palletizing and wrapping film assembly is further explained below, with the film wrapping process of the present invention as follows:

[0183] like Figure 29As shown, the first step is to manually pull the end of the packaging film 12 on the film tube 840 to position B on the pallet 13 as the default position. Then, the palletizing machine gripper assembly picks up the can lid packaging bag 11 and places it on the pallet 13 with the packaging film 12. Next, the X-axis support 83 drives the film winding assembly 84 to move laterally, so that the packaging film 12 falls on the first layer of can lid packaging bags 11. At this time, the palletizing machine gripper picks up the can lid packaging bag 11 again and places it on the packaging film 12. Then, the automated palletizing and film winding operation can begin. That is, the X-axis support 83 drives the film winding assembly 84 to move laterally back and forth. After each layer is wound, the Y-axis support drives the X-axis support 83 to rise a certain distance. After the film winding of the top layer of can lid packaging bags 11 is completed, the film winding assembly... The component 84 is located on the X-axis support 83 near the Z-axis support 82. The Z-axis support 82 drives the X-axis support 83 to descend to the lowest point, causing the packaging film 12 of the film tube 840 to be pulled down in its entirety. Then, the cutter cylinder 855 drives the flywheel blade 853 to move laterally and extend it out of the cutter housing 850. The drag chain 859 drives the cutter sliding block 857 to move laterally on the cutter lateral guide rail 858, thereby driving the flywheel blade 853 to move laterally and cut the packaging film 12. The cut packaging film 12 adheres to the side wall of the stacked can lid packaging bag 11 under its own properties, thus completing the entire palletizing and wrapping film operation. Finally, the pallet conveyor belt 811 transports the pallet 13 out of the palletizing and wrapping film assembly.

[0184] pass Figure 1 , 3 As can be seen, the automatic packaging line has two production lines, hence the attachment. Figure 1 , 3 There are also two magnetic belt conveyor devices in the middle, but the following will only describe one magnetic belt conveyor device in detail.

[0185] like Figures 30-33 As shown, the magnetic belt conveyor assembly 9 includes a frame 91, a conveyor belt 92, a fixed frame 93, a swing frame 94, and a drive motor 96 for driving the conveyor belt 92. The fixed frame 93 and the swing frame 94 are both fixed to the frame 91. The conveyor belt 92 is arranged around the contours of the fixed frame 93 and the swing frame 94 to form a circulating conveyor belt 92. Figure 31As shown, magnetic strips 97 are provided on the working surfaces of the fixed frame 93 and the swing frame 94 (the working surfaces refer to the bottom surfaces of the fixed frame and the swing frame used to adsorb the can lids). The function of the magnetic strips 97 is to adsorb and fix the can lids onto the conveyor belt 92, so that they are automatically transported from the head end to the end end of the conveyor belt 92 and fall down automatically. Therefore, no magnetic strips 97 are provided at the end of the fixed frame 93. The swing frame 94 is connected to the fixed frame 93 by a hinge 95, so that the swing frame 94 can swing relative to the fixed frame 93. The bottom of the swing frame 94 is provided with a cylinder 980 assembly 8. The swing frame 94 is connected to the movable rod 981 of the cylinder 980 assembly 8 through the support base 982 fixed at its bottom. Thus, the swing frame 94 can be driven to swing by the movement of the movable rod 981 of the cylinder 980, thereby adjusting the angle and controlling the distance between the swing frame 94 and the conveyor belt of the automatic packaging line 914.

[0186] Specifically, such as Figures 30-31 As shown, a tension control assembly 99 is also provided on the frame 91. The tension control assembly 99 includes a main drive roller 990, a fixed plate 991, and a tension roller 993. The main drive roller 990 is located at the top of the fixed frame 93, or it can be located at the bottom, as long as it is not at the same horizontal plane as the conveyor belt 92 on the fixed frame 93, so that the trajectory of the conveyor belt 92 when passing the main drive roller 990 protrudes from the surface of the fixed frame 93. The tension roller 993 is located on one side of the main drive roller 990 and is not at the same horizontal height. The tension roller 993 is rotatably fixed to the tension shaft 994 by bearings. The fixed plate 991 is provided with a guide rail groove 992. The end of the tensioning shaft 994 is located in the guide rail groove 992. A positioning block 995 is provided on one side of the guide rail groove 992 of the fixed plate 991. The positioning block 995 is provided with a through hole. The end of the tensioning shaft 994 is provided with a screw 996. The screw 996 passes through the through hole and is screwed with a nut 997. Thus, by rotating the nut 997 to adjust the screw 996, the distance between the tensioning shaft 994 and the positioning block 995 can be changed. This can drive the tensioning roller 993 to move left and right in the guide rail groove 992, thereby adjusting the tension of the conveyor belt 92.

[0187] Specifically, such as Figure 32 As shown, a first reinforcing plate 910 and a second reinforcing plate 911 are provided at the connection between the fixed frame 93 and the swing frame 94. There are two first reinforcing plates 910, which are fixed to the fixed frame 93 and the swing frame 94 respectively. One side of the second reinforcing plate 911 is fixed to the first reinforcing plate 910 of the fixed frame 93, and the other side is fixed to the first reinforcing plate 910 of the swing frame 94 through a pivot 912. Thus, the connection between the fixed frame 93 and the swing frame 94 can be strengthened by the first reinforcing plate 910 and the second reinforcing plate 911, thereby improving stability.

[0188] It should be noted that, since there are two conveyor belts 92 in the attached figure, the two swing frames 94 are connected by a connector 913, and the support base 982 is located at the bottom of the connector 913. Thus, the two swing frames 94 can be driven by a set of cylinder 980 assembly 8.

[0189] It should be noted that the above embodiments only show the connection between the fixed frame 93 and the swing frame 94 using a hinge 95. This hinge 95 is the angle adjustment device described in the claims. This method is relatively the lowest cost and most reliable, which is beneficial for the implementation of the technical solution. However, it is not limited to this; it can also be a hinged connection, or a rotatable bearing and support 982. Based on the above design concept, those skilled in the art can select a suitable angle adjustment device according to the actual situation. As long as one end of the swing frame 94 can swing with the other end as the base point, it should be within the protection scope of this invention.

[0190] Working principle of magnetic belt conveyor assembly:

[0191] By placing the swing frame 94 on the conveyor belt of the automatic packaging line 914 and the fixed frame 93 on the conveyor belt of the manual packaging line 914, when the automatic packaging line 914 malfunctions or too many can lids accumulate in front, the starting cylinder 980 drives the swing frame 94 to descend, so that the magnetic strip 97 at the bottom of the swing frame 94 can attract the can lids on the conveyor belt of the automatic packaging line 914. Since the can lids are attracted on the conveyor belt 92, as the conveyor belt 92 moves to the end of the fixed frame 93, they automatically fall onto the conveyor belt of the manual packaging line 914 below because there is no magnetic strip 97 attracting them. This realizes the transfer of can lids from the automatic packaging line 914 to the conveyor belt of the manual packaging line 914.

[0192] The embodiments described above merely illustrate the best implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
