Description

Technical Field

[0001] The invention belongs to the technical field of can stacking machines, and in particular relates to a can stacking machine, an anti-can overflow component and an anti-can overflow method. Background Art

[0002] At the back end of the canning production line, a palletizer is required to palletize the unsealed cans, which are then packed using a cable tie machine and wrapped with film using a wrapping machine for the next step of packaging and transportation. In the above process, various types of equipment are required, involving the transfer and use of various logistics such as cans, palletizing trays, padding paper, top plates, cable ties, and films.

[0003] Chinese invention patent CN116002387A discloses a canned can stacker, comprising a frame, a stacking plate conveying device, a feeding device, a transfer device and a partition device, wherein the stacking plate conveying device is arranged below the frame, the stacking plate conveying device is suitable for transporting stacking plates, the feeding device, the transfer device and the partition device are arranged above the frame, the feeding device is suitable for transporting canned cans in an array form, and the transfer device is suitable for transferring the canned cans at the feeding device to the stacking plate; the canned can stacker has poor stacking effect and low stacking efficiency.

[0004] Chinese invention patent CN112777315A provides a stacking device, which relates to the technical field of can conveying equipment, including: a can rejection component and a conveying component; through the arrangement of the can rejection component, a magnetic conveying part is used to absorb cans in an upright state in a first conveying area and convey them to a second conveying area, and cans in a tilted state cannot be absorbed by the magnetic conveying part; the can stacking machine is difficult to operate and has a low safety factor.

[0005] In actual use, due to the number of cans in each stacking layer and the arrangement of cans in the stacker, a certain number of cans need to be picked up and placed regularly, resulting in one column of cans having one more can than the other columns when grabbing the cans. When the cans are arranged and fed to the stop position, the column with the extra cans stops feeding earlier than the other columns. The cans in this column are squeezed relative to the other cans, resulting in can popping out. The bottom of the popped out can contacts and squeezes the surrounding cans to form a concave can. When the can popping out is serious, the cans will even be squeezed out, causing faults such as misaligned can arrangement and can smashing, poor layer paper placement, and chaotic can scanning caused by undetected stacking height.

[0006] When the cans are pushed and stacked, if the position of the cans is offset, they cannot be accurately inserted into the cans, which reduces the accuracy of the subsequent stacking of the cans. When there are dust and impurities on the outer surface of the cans, it will not only reduce the cleaning effect of the cans, but also affect the subsequent stacking position of the cans. At the same time, if a can has a dent in the transmission process, if the dented can is still stacked, the stacking accuracy and quality of the subsequent cans will be reduced.

[0043] like Figure 1-10As shown, the can stacking machine mainly realizes the stacking process of cans, including two fixed frames 1, a conveyor belt 7 is connected between the fixed frames 1, and the conveyor belt 7 conveys the cans. A plurality of baffles 9 are evenly arranged on the top of the conveyor belt 7, and the length of the baffles 9 is less than the length of the conveyor belt 7. A top plate 10 is arranged above the plurality of baffles 9, and the top plate 10 connects the plurality of baffles 9, while the bottom of the baffle 9 contacts the top of the conveyor belt 7 but does not convey the cans. The baffles 9 separate the cans during the conveying process to improve the conveying stability and the flatness of the subsequent stacking. A stacking frame 11 is arranged on one side of the conveyor belt 7, and a bearing platform 14 is movably connected inside the stacking frame 11, and the bearing platform 14 is not inside the stacking frame 11. The stacking frame 11 is continuously lowered, and batches of cans are continuously stacked on the supporting platform 14. A splicing frame 18 is movably connected above the stacking frame 11. The splicing frame 18 continuously moves above the conveyor belt 7 and the stacking frame 11 and pushes the cans for stacking. A plurality of adsorption tubes 24 are evenly and movably connected to one side below the splicing frame 18. The adsorption tubes 24 adsorb and move the tail cans with the help of negative pressure. When the same batch of cans are stacked on the supporting platform 14 later, the tail cans are placed at the end to achieve uniform and equidistant stacking. A plurality of push rods 20 are evenly and movably connected to the other side below the splicing frame 18. The push rods 20 push the front and rear cans of the same batch to improve the integrity and convenience of subsequent stacking of the cans.

[0044] A plurality of legs 2 are evenly arranged at the bottom of the fixed frame 1, and the arrangement of the legs 2 improves the stability of the fixed frame 1. A plurality of moving rods 12 are evenly arranged at the bottom of the stacking frame 11, and a moving wheel is arranged at the bottom of the moving rod 12, so that the moving rod 12 can drive the stacking frame 11 to move, thereby realizing stacking and unloading. A mounting plate 3 is arranged on one side of the outer wall of the fixed frame 1, and a driving motor 4 is arranged on the top of the mounting plate 3. An active roller 5 is connected to the inner wall of one side of the conveyor belt 7 for transmission, and a driven roller 6 is connected to the inner wall of the other side of the conveyor belt 7 for transmission. The output end of the driving motor 4 passes through the fixed frame 1 and is fixedly connected to the side wall of the active roller 5. The driving motor 4 starts and drives the active roller 5 to rotate, and the active roller 5 rotates and drives the conveyor belt 7 to rotate and convey the cans, and the arrangement of the driven roller 6 improves the stability and tension of the conveyor belt 7.

[0045] A plurality of conical connecting rods 8 are evenly arranged on one side facing each other of the fixed frame 1, and the other ends of the conical connecting rods 8 are fixedly connected to the side walls of the baffle 9. The position of the baffle 9 is fixed by means of the conical connecting rods 8, and the baffle 9 will not move along the transmission of the conveyor belt 7. A control component is arranged on one side of the fixed frame 1, and the control component electrically controls each electrical component. There is a gap between the fixed frame 1 and the conveyor belt 7, and the deformed cans can be discharged along the gap. The diameter of the conical connecting rod 8 gradually increases from the end of the fixed frame 1 to the end of the baffle 9. After the deformed cans are discharged, the deformed cans contact with the conical connecting rod 8. A recycling frame is arranged under the conveyor belt 7, and the recycling frame matches the side walls of the conical connecting rod 8. With the help of the shape of the conical connecting rod 8, the cans fall into the recycling frame along the gap between the fixed frame 1 and the conveyor belt 7 for recycling.

[0046] An electric stacking telescopic rod 13 is provided at the bottom of the stacking frame 11, and the top output end of the electric stacking telescopic rod 13 is fixedly connected to the bottom of the carrying platform 14. The electric stacking telescopic rod 13 is started and drives the carrying platform 14 to move up and down, and the carrying platform 14 drives the top can pile to move up and down, thereby realizing the continuous stacking process of the cans. A plurality of top grooves 25 are evenly arranged on the top of the stacking frame 11 close to the conveyor belt 7, and an electric blocking telescopic rod 26 is provided at the bottom of the top groove 25. An intercepting rod 27 is provided on the top of the electric blocking telescopic rod 26. When the electric blocking telescopic rod 26 is started and drives the intercepting rod 27 at the top output end to move upward and extend out of the top groove 25, the intercepting rod 27 blocks and corrects the cans of the same batch to avoid uneven distribution of cans of the same batch and reduce the subsequent stacking accuracy.

[0047] Slide rails 15 are symmetrically arranged on both sides of the top of the stacking frame 11. The top of the slide rails 15 is slidably connected to an electric slide seat 16. The electric slide seat 16 can reciprocate along the slide rails 15. A vertical rod 17 is arranged on the top of the electric slide seat 16. The top of the vertical rod 17 is fixedly connected to the bottom of the splicing frame 18. The electric slide seat 16 moves and drives the top splicing frame 18 to move through the vertical rod 17. A plurality of electric pusher telescopic rods 19 are evenly arranged at the bottom of the splicing frame 18. The bottom output end of the electric pusher telescopic rod 19 is fixedly connected to the top of the push rod 20. After the electric pusher telescopic rod 19 is started and the output end is extended, the electric pusher telescopic rod 19 drives the push rod 20 to move downward, and the push rod 20 extends into the interior of the cans in the front and rear positions of the same batch. When the splicing frame 18 moves, the push rod 20 correspondingly drives the cans of the same batch to the top of the carrier 14 for stacking.

[0048] A plurality of negative pressure pumps 21 are evenly arranged on the top of one side of the splicing frame 18 close to the conveyor belt 7, and a hose 23 is arranged at the output end of the negative pressure pump 21. When the negative pressure pump 21 is started, suction force is applied to the hose 23. A plurality of electric clamping telescopic rods 22 are evenly arranged on the bottom of one side of the splicing frame 18 close to the conveyor belt 7. The bottom output end of the electric clamping telescopic rod 22 is connected to the top of the adsorption tube 24. When the electric clamping telescopic rod 22 is started, the output end drives the adsorption tube 24 to move up and down, and the other end of the hose 23 is connected to the inside of the adsorption tube 24. When the adsorption tube 24 is inserted into the inside of the tail can and squeezed and contacted with the bottom of the tail can, the negative pressure pump 21 is started and negative pressure suction is applied to the adsorption tube 24 through the hose 23. The adsorption tube 24 applies suction force to the bottom of the tail can, thereby adjusting the position of the tail can to improve the stacking accuracy of the cans.

[0049] The anti-overflow can assembly is used for the above-mentioned can stacking machine, including a side groove 28, which is opened at the top of one side of the fixed frame 1. A support block 29 is arranged inside the side groove 28. The bottom of the top plate 10 is fixedly connected to the top of the support block 29, and the position of the support block 29 does not change. A docking hole 31 is opened inside the support block 29, and clean gas flows inside the docking hole 31. An exhaust pump 30 is arranged on one side of the fixed frame 1. The output end of the exhaust pump 30 passes through the fixed frame 1 and is connected to the docking hole 31. The exhaust pump 30 is started and the clean gas is discharged into the docking hole 31 for circulation. A regulating hole 32 is connected to the side of the docking hole 31 close to the baffle 9. The internal sealing and sliding connection of the regulating hole 32 is a magnetic rod 33. Part of the gas inside the docking hole 31 can enter the regulating hole 32. At the same time, the magnetic rod 33 moves along the regulating hole 32 to block the cans, prevent the cans from overflowing, and improve the stacking flatness of the cans.

[0050] A plurality of side holes 35 are evenly provided on the upper and lower sides of the regulating hole 32, and a cleaning hole 36 is symmetrically provided on the upper and lower sides of the magnetic rod 33 on one side of the supporting block 29. The side holes 35 and the cleaning holes 36 are evenly connected. The clean gas inside the regulating hole 32 enters the cleaning hole 36 along the plurality of side holes 35 and is finally discharged along the cleaning hole 36. Not only can the outer surface of the can be cleaned by wind, but also the amount of gas inside the docking hole 31 can be adjusted accordingly, so as to achieve the stability of the can transmission and the accuracy of the position.

[0051] An electromagnetic ring 41 is provided on the inner wall of one side of the regulating hole 32, and a connecting spring 42 is provided on one side of the electromagnetic ring 41. The other end of the connecting spring 42 is fixedly connected to the side wall of the magnetic rod 33. The setting of the connecting spring 42 further improves the elastic reset performance of the magnetic rod 33. The magnetic properties of the end faces facing the electromagnetic ring 41 and the magnetic rod 33 are the same. When the current of the electromagnetic ring 41 increases, the magnetic repulsion force applied by the electromagnetic ring 41 to the magnetic rod 33 increases, and the magnetic rod 33 stretches the connecting spring 42 to move away from the end of the electromagnetic ring 41. A rubber head 34 is provided at the end of the other end of the magnetic rod 33. The rubber head 34 is elastic, thereby reducing the extrusion and collision force between the rubber head 34 and the can, thereby ensuring the integrity of the can. The magnetic rod 33 is matched with multiple side holes 35. When the magnetic rod 33 moves along the regulating hole 32 toward the end of the electromagnetic ring 41, the blockage of the side hole 35 by the magnetic rod 33 increases, the amount of clean gas entering the cleaning hole 36 along the side hole 35 of the regulating hole 32 decreases, and the corresponding amount of clean gas inside the docking hole 31 increases.

[0052] A plurality of distance sensors 43 are evenly arranged between the facing end surfaces of the two baffles 9 close to the support block 29. The distance sensors 43 are used to detect the distance value between the two baffles 9, so as to quickly determine the position of the cans between the two baffles 9 and the cleanliness and completion of the outer surface, and adjust the position of the cans accordingly to ensure the accuracy and cleanliness of the subsequent stacking of the cans.

[0053] An inner hole 40 is provided on the top of the baffle plate 9 near the side of the support block 29, and the inner hole 40 is used for the movement of the magnetic rod 33 or the can. A transfer hole 37 is provided inside the top plate 10, and the other end of the docking hole 31 passes through the fixing frame 1 and the top plate 10 and is connected with one end of the transfer hole 37, so that the clean gas inside the docking hole 31 can enter the inside of the transfer hole 37, and a matching hole 38 is provided inside the baffle plate 9 near the side of the inner hole 40, and two exhaust holes 39 are symmetrically provided on the side of the matching hole 38 near the inner hole 40, and the other end of the transfer hole 37 passes through the top plate 10 and is connected to the matching hole 38, the cleaning hole 36 corresponds to the exhaust hole 39, and the cleaning hole 36 and the exhaust hole 39 are matched with the inner hole 40, and the clean gas inside the transfer hole 37 is discharged along the matching hole 38 and the exhaust hole 39, so as to adjust the position of the cans in the other direction and remove impurities by wind, so as to ensure the accuracy and cleanliness of the subsequent stacking of the cans.

[0054] Due to the number of cans in each layer and the arrangement of cans in the stacking machine, the suction tube 24 needs to regularly pick up and place a certain number of cans, resulting in one column of cans having one more can than the other columns when grabbing the cans. When the cans are arranged and fed to the stop position, the column with the extra cans stops feeding earlier than the other columns. This column of cans is squeezed relative to the other cans, causing can popping. The bottom of the popped can contacts and squeezes the surrounding can bodies to form a concave can. When the can popping is serious, the cans will even be squeezed out, causing faults such as cans being misplaced and the push rod 20 or the suction tube 24 hitting the cans, poor layer paper placement, and chaotic can scanning caused by undetected stacking height.

[0055] When the cans are pushed and stacked by the push rod 20, if the position of the cans is offset, the subsequent push rod 20 and the adsorption tube 24 may not be accurately inserted into the cans, thereby reducing the subsequent stacking accuracy of the cans; and when there are dust and impurities on the outer surface of the cans, not only will the cleaning effect of the cans be reduced, but also the stacking position of the cans will be affected subsequently; at the same time, if the cans have a dent in the transmission process, if the dented cans are still stacked subsequently, the stacking accuracy and quality of the subsequent cans will be reduced.

[0056] Therefore, in actual use, Figure 1After determining the orientation, the cans are conveyed from left to right on the top of the conveyor belt 7, and the multiple cans in the same row are divided into zones by multiple baffles 9. The control component controls the drive motor 4 to start, and the output end of the drive motor 4 drives the active roller 5 to rotate, and the active roller 5 drives the conveyor belt 7 to rotate, and the conveyor belt 7 drives the cans to be continuously conveyed backwards. When the conveyor belt 7 conveys the cans of the same batch and separates from the baffle 9, the control component controls the drive motor 4 to stop working, and the conveyor belt 7 stops conveying. At the same time, the control component controls the electric slide 16 to start and move to the left along the slide rail 15 to the top of the conveyor belt 7, and multiple electric push telescopic rods 19 are started and drive the push rod 20 to move downward, and the push rod 20 is inserted into the cans at the head end and the penultimate end. At the same time, the electric clamping telescopic rod 22 is started and drives the adsorption tube 24 to be inserted downward into the multiple cans at the tail end, and the electric blocking telescopic rod 26 is reversed. The intercepting rod 27 is started and driven to move downward along the top groove 25 and penetrate into the top groove 25. Then the control component controls the electric slide 16 to start in the opposite direction and move rightward along the slide rail 15 to above the stacking frame 11. The electric slide 16 drives the splicing frame 18 to move synchronously to above the stacking frame 11 through the vertical rod 17. The splicing frame 18 drives multiple electric pushing telescopic rods 19 to move above the supporting platform 14. Then the electric pushing telescopic rod 19 drives multiple cans to move synchronously to above the supporting platform 14 through the push rod 20. At this time, the multiple cans adsorbed and fixed by the adsorption tube 24 have not moved to above the supporting platform 14, thereby completing the stacking process of the same batch of cans. After stacking is completed, the layer of paper is placed on the top of the cans, the electric stacking telescopic rod 13 is started and drives the supporting platform 14 to move downward, and the supporting platform 14 drives the top cans to move downward a certain distance, thereby completing a can loading process.

[0057] At this time, since the adsorption tube 24 still fixes some cans, and the stacking quantity of cans on the same layer is different from the loading quantity on the same row of the conveyor belt 7, the negative pressure pump 21 starts and applies negative pressure suction. The negative pressure pump 21 applies suction force to the adsorption tube 24 through the hose 23. The adsorption tube 24 adsorbs and fixes multiple cans at the tail end. At the same time, the electric clamping telescopic rod 22 starts in the reverse direction and drives the multiple cans at the tail end to move upward through the adsorption tube 24. The cans are separated from the top of the conveyor belt 7. At the same time, the electric blocking telescopic rod 26 starts and drives the top intercepting rod 27 to move upward and separate from the top groove 25. The conveyor belt 7 starts and drives the cans to continue to move. At this time, the control component controls the power-on current of the electromagnetic ring 41 to increase, and the electromagnetic ring 4 When the magnetic repulsive force applied to the magnetic rod 33 increases, the magnetic rod 33 stretches the connecting spring 42 and moves outward along the regulating hole 32, and the magnetic rod 33 drives the rubber head 34 to move. The rubber head 34 passes through the inner hole 40 and applies a blocking effect on one side of the can, so that the can cannot continue to be transmitted backward, and a gap appears in the cans on that side. When the can moves backward for a body position, the control component controls the power-on current of the electromagnetic ring 41 to restore the initial value, and drives the magnetic rod 33 to move in the opposite direction and return to its original position under the elastic force of the connecting spring 42. The magnetic rod 33 drives the rubber head 34 to move in the opposite direction and return to its original position along the inner hole 40, and the rubber head 34 is freed from the blocking effect on the cans on the opposite side, and multiple cans continue to be transmitted backward.

[0058] When the cans at the head end are squeezed and contacted with the intercepting rod 27, the conveyor belt 7 stops conveying, and the above process is repeated and the cans are pushed to the top of the supporting platform 14 for stacking through the push rod 20. At this time, the electric clamping telescopic rod 22 drives the cans to move downward to the top of the conveyor belt 7 through the adsorption tube 24. At the same time, the negative pressure pump 21 stops working, and the adsorption tube 24 is separated from the negative pressure adsorption of the cans. The cans then fall on the top of the conveyor belt 7 and wait for subsequent transmission. The above process is repeated continuously, and the magnetic rod 33 drives the rubber head 34 to start at intervals and block different batches of cans, and the adsorption frequency of the adsorption tube 24 to the cans is matched with it, so as to meet the matching of the transmission quantity of the cans and the stacking quantity to avoid the can overflowing.

[0059] When the side cans move between the two baffles 9, multiple distance sensors 43 detect the distance value, and the control component controls the exhaust pump 30 to start and introduce clean gas into the docking hole 31. Part of the clean gas enters the regulating hole 32 and is discharged along multiple side holes 35 and cleaning holes 36, and then the outer surface of one side of the can is cleaned by wind through the inner hole 40, and another part of the clean gas enters the matching hole 38 along the docking hole 31 and the transfer hole 37, and is finally discharged along multiple exhaust holes 39, and then the outer surface of the other side of the can is cleaned by wind, effectively improving the cleaning effect of the can.

[0060] In combination with the cylindrical shape of the can itself, when the can moves with the conveyor belt 7, the distance value detected by the distance sensor 43 keeps changing. At the same time, according to the distance value change time detected by the distance sensor 43, the position of the can and the cleanliness of the outer surface are obtained. Specifically, when the can moves with the conveyor belt 7 to between the distance sensors 43, if the interval time of the distance value detected by the distance sensor 43 decreases, it means that the distance between the can and the previous can is small, the can is located to the right, and the can needs to be pushed to the left for part of the distance. Then, when the can moves to the end of the inner hole 40 and the rubber head 34 is in the When it is at the right end of the can, the control component controls the current of the electromagnetic ring 41 to increase, so that the magnetic repulsion of the electromagnetic ring 41 on the magnetic rod 33 increases and drives the magnetic rod 33 to stretch the connecting spring 42 to move away from the end of the electromagnetic ring 41, and the magnetic rod 33 drives the rubber head 34 to move. The rubber head 34 contacts with the can and blocks the can, and the conveyor belt 7 continues to convey forward. When the can moves to the left relative to the conveyor belt 7 and the distance between it and the previous can returns to the initial value, the controller controls the current of the electromagnetic ring 41 to decrease, and the magnetic rod 33 is driven to move in the opposite direction and return to its original position under the elastic force of the connecting spring 42.

[0061] Similarly, when the distance sensor 43 detects that the interval time of the distance value increases, it means that the distance between the can and the previous can is large, the can is located on the left, and the can needs to be pushed part of the distance to the right. Then, when the can moves with the conveyor belt 7 and the middle position exceeds the end of the rubber head 34, the magnetic rod 33 drives the rubber head 34 to move and push the left part of the can, and the can moves to the right, thereby ensuring that the distance between the can and the previous can meets the requirements.

[0062] At the same time, when the distance values ​​detected by the two distance sensors 43 are not equal, it means that the front and rear positions of the cans between the two baffles 9 are offset. For example, when the distance value detected by the distance sensor 43 on the front side decreases, while the distance value detected by the distance sensor 43 on the rear side increases, and the decrease value is equal to the increase value, it means that the cans are offset on the front side. When the cans move to the end of the inner hole 40 and the center position reaches the end of the cleaning hole 36, the control component controls the electromagnetic ring 41 to increase the current, so that the electromagnetic ring 41 increases the magnetic repulsion force on the magnetic rod 33 and drives the magnetic rod 33 to pull The extended connecting spring 42 moves away from the end of the electromagnetic ring 41, and the blockage of the side hole 35 by the magnetic rod 33 is reduced. At the same time, the magnetic rod 33 drives the rubber head 34 not to contact the can. The amount of clean gas inside the docking hole 31 entering the cleaning hole 36 along the regulating hole 32 and the side hole 35 increases, and the amount of clean gas discharged from the cleaning hole 36 increases. With the help of this amount of clean gas, wind force is applied to the front side of the can, so that the can moves to the rear side and restores the initial value, thereby realizing the adjustment of the front and rear position of the can, ensuring the accuracy of the position of the can and the accuracy of the subsequent stacking.

[0063] Similarly, when the distance value detected by the distance sensor 43 on the front side increases, while the distance value detected by the distance sensor 43 on the rear side decreases, and the decrease value is equal to the increase value, it means that the can is offset on the rear side. When the can moves to the end of the inner hole 40 and the center position reaches the end of the cleaning hole 36, the control component controls the electromagnetic ring 41 to reduce the current, and drives it to move closer to the end of the electromagnetic ring 41 under the elastic force of the connecting spring 42, and the blockage amount of the side hole 35 by the magnetic rod 33 increases. The amount of clean gas inside the docking hole 31 entering the cleaning hole 36 along the regulating hole 32 and the side hole 35 decreases, and the amount of clean gas from the docking hole 31 entering the matching hole 38 along the transfer hole 37 increases. Finally, the amount of clean gas discharged from the matching hole 38 along the multiple exhaust holes 39 increases. With the help of this clean gas, wind force is applied to the rear side of the can, so that the can moves to the rear side and restores the initial value, further ensuring the stability and accuracy of the position of the can.

[0064] When a dent appears on one side of the can, if the cans are still stacked, it will affect the stacking effect of the entire cans, and the can needs to be removed. When the dented can moves to the end of the distance sensor 43, the distance values ​​detected by the multiple distance sensors 43 are not equal, and the distance value detected by the distance sensor 43 on one side is greater than the set maximum distance preset value, which means that the can is dented. When the can moves to the end of the inner hole 40, the control component controls the electromagnetic ring 41 to cut off the power, and the magnetic repulsion force exerted by the electromagnetic ring 41 on the magnetic rod 33 disappears, then the magnetic rod 33 is driven to the side under the elastic force of the connecting spring 42. The end near the electromagnetic ring 41 moves to the maximum distance, and the magnetic rod 33 blocks the multiple side holes 35. The clean gas inside the docking hole 31 cannot be discharged along the cleaning hole 36, and the clean gas inside the docking hole 31 is discharged along the transfer hole 37 and the matching hole 38 along the multiple exhaust holes 39. The wind force applied by the exhaust holes 39 to the rear side of the can reaches the maximum value. The recessed can slides out of the baffle 9 along the inner hole 40, and reaches the end of the conical connecting rod 8 under the conveying action of the conveyor belt 7, and reaches the inside of the recycling box under the blocking action of the conical connecting rod 8 for recycling, thereby preventing the recessed can from affecting the subsequent stacking quality.

[0065] At the same time, when the depressed can is discharged, the control component controls the electromagnetic ring 41 to be energized and restore the initial value, and the corresponding magnetic rod 33 restores the initial value. When the cans need to be blocked and given way in intervals later, since the depressed can has been pushed out, the control component controls the magnetism of the electromagnetic ring 41 to remain unchanged. The magnetic rod 33 and the rubber head 34 do not need to block the can. The extra can will compensate for the depressed can, thereby ensuring the integrity and accuracy of the stacked cans, and the above process is repeated to stack subsequent cans.

[0066] The device is easy to operate, stable and efficient, meets the actual needs of large-scale can stacking processing, has stronger adaptability, higher stability, and stronger controllability, effectively ensures that the cans are stacked safely and stably, and greatly reduces the labor intensity of operators; at the same time, when stacking the cans, the magnetic rod 33 and the rubber head 34 can be moved to block the cans at intervals to avoid squeezing and bursting of the cans during stacking, thereby reducing the flatness and safety of the cans; and before stacking the cans, the outer surface of the cans can be cleaned by wind to improve the cleanliness and safety of the cans. Integrity, avoiding contamination of subsequent cans and reducing the stacking quality; when the position of the cans between the baffles 9 is offset, the position of the cans between the baffles 9 can be adjusted with the help of the rubber head 34 and the clean gas, so as to ensure the accuracy of the position of the cans and the stability of the subsequent stacking pushed by the push rod 20; and when a concave can appears, the clean gas discharged from the exhaust hole 39 will push the concave can out, and the can will no longer be blocked subsequently, thereby realizing the removal of the concave cans, thereby effectively improving the subsequent stacking quality of the cans.

[0067] The anti-counterfeiting method of the anti-counterfeiting can assembly includes the following steps:

[0068] S1. After the conveyor belt 7 drives the same batch of cans to move to the end, multiple push rods 20 are inserted into the cans, and the adsorption tubes 24 adsorb some of the cans. The cans are pushed above the supporting platform 14, and the conveyor belt 7 continues to start and transport the cans. The magnetic rod 33 extends along the regulating hole 32 and blocks the subsequent cans from moving one position with the conveyor belt 7.

[0069] S2. When the can moves to the end of the inner hole 40, part of the clean gas inside the docking hole 31 enters into the multiple cleaning holes 36 along the regulating hole 32 and the side hole 35, and the clean gas is discharged along the cleaning holes 36 to clean one side of the can by wind, and another part of the clean gas inside the docking hole 31 enters into the multiple exhaust holes 39 along the transfer hole 37 and the matching hole 38, and the clean gas inside the exhaust hole 39 is discharged to clean the other side of the can by wind.

[0070] S3. When the distance value detected by the front distance sensor 43 increases and the distance value detected by the rear distance sensor 43 decreases, and the decrease value is equal to the increase value, after the can moves to the end of the inner hole 40, the magnetic rod 33 moves closer to the end of the can, and the amount of the side hole 35 blocked by the magnetic rod 33 decreases. The amount of clean gas entering the cleaning hole 36 along the regulating hole 32 and the side hole 35 inside the docking hole 31 increases, and the clean gas is discharged from the cleaning hole 36 and drives the can to move backward.

[0071] S4. When the distance values ​​detected by multiple distance sensors 43 are not equal, and the distance value detected by the distance sensor 43 on one side is greater than the preset maximum distance value, after the can moves to the end of the inner hole 40, the magnetic rod 33 moves away from the end of the can, and the magnetic rod 33 blocks the multiple side holes 35. The amount of clean gas entering the multiple exhaust holes 39 along the transfer hole 37 and the matching hole 38 inside the docking hole 31 increases, and the clean gas exerts wind force on the rear side of the can and causes the can to separate from the baffle 9 along the inner hole 40.

[0072] By further limiting the anti-overflow method, the anti-overflow effect of cans is improved and the stacking quality of cans is guaranteed.
