Description

Technical Field

[0001] This invention relates to the field of carton stacking technology, specifically to a carton stacking device for a carton production line. Background Technology

[0002] In the packaging industry, cardboard boxes are arguably the most widely used packaging products, occupying a pivotal and indispensable position in various industries. With the development of the global economy and the improvement of people's living standards, the demand for packaging in various industries continues to grow. As a traditional yet modern packaging material, cardboard boxes have become the first choice for many companies due to their unique advantages. When traditional cardboard boxes are manufactured, they are flat immediately after processing. As a result, when multiple boxes are stacked, there is a lack of effective connections and fixing points between them. Therefore, when subjected to external forces during handling, the boxes may collapse or scatter, causing damage to the boxes themselves. Furthermore, the collapse of the boxes may also pose a threat to the personal safety of warehouse workers. Summary of the Invention

[0003] This invention increases the friction between cartons by using a starch-based anti-slip liquid, effectively preventing the risk of collapse caused by cartons shifting or sliding during stacking. This ensures a neat stacking structure and guarantees stability during subsequent handling. It also prevents cartons from collapsing during handling due to insufficient friction between them. At the same time, the airflow from the air outlet quickly dries the starch-based anti-slip liquid, preventing the cartons from sticking together due to undried liquid and affecting subsequent use.

[0009] Preferably, one end of the valve is fixedly connected to a valve stem, and the other end of the valve stem extends through the connecting pipe C to the outside and is connected to the connecting rod.

[0010] Preferably, the nozzle is located inside the empty slot B, and multiple sets of nozzle holes are provided on the outside of the nozzle.

[0011] Preferably, the lower end of the support plate is connected to four sets of springs B, and the other end of each of the four sets of springs B is connected to the bottom of the stacking groove.

[0012] Preferably, a telescopic rod is fixedly connected to the lower end of the support plate, and the other end of the telescopic rod is connected to electrode plate A. Electrode plate A and electrode plate B are electrically connected, and electrode plate A and electrode plate B are located on the same vertical plane.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention increases the friction between cartons by using a starch-based anti-slip liquid, effectively preventing the risk of collapse caused by cartons shifting or sliding during stacking. This ensures a neat stacking structure and guarantees stability during subsequent handling. It also prevents cartons from collapsing during handling due to insufficient friction between them.

[0014] This invention automatically triggers an alarm when the number of cartons stacked inside the stacking slot is about to reach its maximum value. It continuously monitors the stacking height and capacity of cartons and provides timely feedback on the stacking status of the stacking slot, preventing cartons from falling and being damaged due to human error and affecting subsequent use. At the same time, by utilizing the telescopic characteristics of the telescopic rod, when electrode plate A and electrode plate B come into contact, the feeding plate still has remaining bearing space, thus providing sufficient buffer time for workers to replace the feeding plate and effectively avoiding cartons falling and being damaged due to untimely response.

[0015] This invention uses a fixed plate that alternately contacts both ends of the feeding plate to continuously correct the position of the cartons on the feeding plate. This returns any misaligned cartons to the center position, preventing them from getting stuck in the stacking slot due to misalignment when they fall in. It also ensures that each layer of cartons is aligned, forming a neat stack, which provides a good foundation for subsequent bundling and handling processes. At the same time, it prevents cartons from getting stuck, eliminating the need for frequent machine stops to handle abnormalities. This keeps the carton stacking process synchronized with the carton output rhythm of the front-end production line, indirectly improving production efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] according to Figure 1 As shown in Figure 7, the present invention provides a carton stacking device for a carton production line, including a conveyor belt 1. A drive roller 2 and a driven roller 8 are rotatably mounted at both ends of the conveyor belt 1, and a bracket is rotatably connected to both ends of the drive roller 2 and the driven roller 8. A guide pipe 6 is installed on one side of the bracket. A fan blade 5 driven by the drive roller 2 rotates inside the guide pipe 6. An air outlet groove 30 is connected to one end of the guide pipe 6. A slider 11 driven by the driven roller 8 slides at both ends of the driven roller 8. A fixing plate 12 is connected to one side of the slider 11. A guide plate 9 is provided on one side of the conveyor belt 1. The surface of the guide plate 9 is respectively provided with slots A24 and slots B25. A piston rod 14 is connected to one side of the fixed plate 12. A piston tube 15 is slidably connected to one end of the piston rod 14. One end of the piston tube 15 is connected to a storage tank 17. The other side of the storage tank 17 is connected to a connecting pipe C19. A valve is provided inside the connecting pipe C19. One end of the valve is connected to a connecting rod 23. The other end of the connecting pipe C19 is connected to a spray pipe 20. The valve is intermittently opened by the carton conveyor. A stacking trough 26 is provided on one side of the guide plate 9. A support plate 27 and a discharge plate 29 slide inside the guide pipe 6. One end of the support plate 27 is connected to the electrode plate A32. An electrode plate B33 is installed at the lower end of the stacking trough 26. One end of the electrode plate B33 is electrically connected to an alarm light 34.

[0020] In an optional embodiment, a motor 3 is installed on one side of the bracket, the output end of the motor 3 is connected to the transmission roller 2, the other end of the transmission roller 2 is connected to the rotating rod 4, the other end of the rotating rod 4 extends through the bracket to the inside of the guide pipe 6 and is connected to the fan blade 5, one end of the guide pipe 6 is connected to the connecting pipe A7, and the other end of the connecting pipe A7 is connected to the air outlet groove 30. When using the device, the transmission roller 2 is driven to rotate by the motor 3. When the transmission roller 2 rotates, it drives the conveyor belt 1 to rotate. When the conveyor belt 1 rotates, it transports the processed cartons. At the same time, when the conveyor belt 1 rotates, it synchronously drives the driven roller 8 to rotate. When the transmission roller 2 rotates, it synchronously drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, it synchronously drives the fan blade 5 to rotate. When the fan blade 5 rotates, it delivers airflow into the connecting pipe A7. After the airflow enters the connecting pipe A7, the connecting pipe A7 delivers the airflow to the air outlet 30 for discharge.

[0021] In an optional embodiment, both ends of the driven roller 8 are connected to reciprocating lead screws 10, and the other ends of the two sets of reciprocating lead screws 10 extend through the bracket to the outside. Both sets of sliders 11 are connected to the ball nut pairs of the reciprocating lead screws 10. As described above, when the driven roller 8 rotates, it will synchronously drive the two sets of reciprocating screws 10 to rotate. When the two sets of reciprocating screws 10 rotate, they will synchronously drive the two sets of sliders 11 to move back and forth alternately on the outside of the reciprocating screws 10. When the two sets of sliders 11 move back and forth alternately, they will synchronously drive the two sets of fixed plates 12 to move back and forth.

[0022] In an optional embodiment, a connecting plate 13 is fixedly connected to one side of each of the two sets of fixing plates 12, one end of each of the two sets of connecting plates 13 is fixedly connected to the piston rod 14, one end of each of the two sets of piston tubes 15 is connected to a connecting pipe B16, the other end of each of the two sets of connecting pipes B16 is connected to the storage tank 17, and a horizontal plate 18 is fixedly connected to the lower end of the storage tank 17, and the horizontal plate 18 is connected to the bracket. The storage tank 17 contains starch-based anti-slip liquid. When the two sets of fixed plates 12 move back and forth alternately, the two sets of fixed plates 12 will drive the two sets of piston rods 14 to move synchronously and alternately through the two sets of connecting plates 13. When the two sets of piston rods 14 move alternately into the piston tube 15, they will continuously squeeze the gas into the connecting tube B16. After the gas enters the connecting tube B16, the connecting tube B16 will transport the gas to the storage tank 17. After the gas enters the storage tank 17, the gas will squeeze the starch-based anti-slip liquid into the connecting tube C19. Since the valve inside the connecting tube C19 is initially closed, the starch-based anti-slip liquid that enters the connecting tube C19 will not enter the nozzle 20.

[0023] In an optional embodiment, a spring A22 is fixedly connected to one side of the connecting rod 23, the other end of the spring A22 is connected to the upper end of the storage groove 17, and the other end of the connecting rod 23 extends into the interior of the empty groove A24. After the conveyor belt 1 transports the carton into the guide plate 9, the carton will slide down the inclined surface inside the guide plate 9 because the inside of the guide plate 9 is inclined. During the sliding process, the carton will come into contact with the connecting rod 23. After the carton comes into contact with the connecting rod 23, it will push the connecting rod 23 to flip and move inside the slot A24. After the carton is separated from the contact with the connecting rod 23, the connecting rod 23 will be reset by the force of the spring A22.

[0024] In an optional embodiment, a valve stem 21 is fixedly connected to one end of the valve, and the other end of the valve stem 21 extends through the connecting pipe C19 to the outside and is connected to the connecting rod 23. As described above, when the carton contacts the connecting rod 23 and causes the connecting rod 23 to flip, the connecting rod 23 will synchronously drive the valve rod 21 to rotate. When the valve rod 21 rotates, the valve rod 21 will open the valve inside the connecting pipe C19. After the valve inside the connecting pipe C19 is opened, the starch-based anti-slip liquid that has entered the connecting pipe C19 will enter the spray nozzle 20 through the connecting pipe C19.

[0025] In an optional embodiment, the nozzle 20 is located inside the empty slot B25, and multiple sets of nozzle holes are provided on the outside of the nozzle 20. As described above, after the starch-based anti-slip liquid enters the nozzle 20, it is sprayed outward through multiple sets of nozzles on the outside of the nozzle 20. When the starch-based anti-slip liquid is sprayed out through the nozzles, it is sprayed onto the side of the carton that contacts the guide plate 9. As the carton moves, it gradually moves to the outside of the guide plate 9. After the carton moves to the outside of the guide plate 9, because the air outlet 30 is located at the lower end of the guide plate 9, the airflow from the air outlet 30 promotes the rapid drying of the starch-based anti-slip liquid sprayed on one side of the carton. When the carton completely detaches from the guide plate 9, it falls into the stacking tray 26. At this time, because the lower end of the carton is sprayed with starch... The starch-based anti-slip liquid ensures that when a cardboard box falls into the stacking groove 26, it will contact the top of the existing cardboard box inside the stacking groove 26, thereby increasing the friction between the cardboard boxes. This effectively prevents the risk of collapse caused by the cardboard boxes shifting or sliding during stacking, ensuring a neat stacking structure and stability during subsequent handling. It also prevents the cardboard boxes from collapsing during handling due to low friction. At the same time, the airflow from the air outlet 30 quickly dries the starch-based anti-slip liquid, preventing the undried starch-based anti-slip liquid from causing the cardboard boxes to stick together and affecting subsequent use. As described above, when the carton contacts the connecting rod 23, the valve inside the connecting pipe C19 will open. When the carton is separated from the connecting rod 23, the valve inside the connecting pipe C19 will automatically close. As a result, when using the device, the spray pipe 20 will intermittently spray starch-based anti-slip liquid to prevent waste of resources and excessive moisture in the equipment.

[0026] In an optional embodiment, the lower end of the support plate 27 is connected to four sets of springs B28, and the other end of each of the four sets of springs B28 is connected to the bottom of the stacking groove 26. After the carton is conveyed into the stacking trough 26, it will fall onto the surface of the feeding plate 29. After the carton falls onto the surface of the feeding plate 29, the weight applied by the feeding plate 29 to the support plate 27 will gradually increase. As the weight of the feeding plate 29 gradually increases, the support plate 27 will gradually descend. When the support plate 27 descends, it will simultaneously compress the four sets of springs B28.

[0027] In an optional embodiment, a telescopic rod 31 is fixedly connected to the lower end of the support plate 27, and the other end of the telescopic rod 31 is connected to the electrode plate A32. The electrode plate A32 and the electrode plate B33 are electrically connected, and the electrode plate A32 and the electrode plate B33 are located on the same vertical plane. The alarm light 34 is installed on one side of the stacking slot 26. As described above, as the support plate 27 gradually descends, the electrode plate A32 will descend synchronously via the telescopic rod 31. When electrode plate A32 descends to contact electrode plate B33, the alarm light 34 will sound an alarm, reminding the staff to replace the discharge plate 29 in time. Because the telescopic rod 31 is retractable, the discharge plate 29 is not fully loaded when electrode plate A32 initially contacts electrode plate B33. As the support plate 27 descends, it will simultaneously compress the telescopic rod 31 to retract, thus allowing the staff time to react when the alarm light 34 alerts them. To prevent subsequent cartons from falling due to staff delays in taking timely measures, an alarm is automatically triggered when the number of cartons stacked inside the stacking slot 26 is about to reach its maximum value. The stacking height and capacity of the cartons are monitored in real time, and the stacking status of the stacking slot 26 is fed back in a timely manner to prevent manual omissions that could lead to cartons falling and being damaged, affecting subsequent use. At the same time, by utilizing the telescopic characteristics of the telescopic rod 31, when the electrode plate A32 and the electrode plate B33 are in contact, the feeding plate 29 still has remaining bearing space, thus providing sufficient buffer time for staff to replace the feeding plate 29 and effectively avoiding cartons falling and being damaged due to untimely response. Simultaneously, as described above, when the two sets of fixing plates 12 move alternately back and forth, they will alternately contact both ends of the feeding plate 29. This prevents the cartons on the upper end of the feeding plate 29 from being misaligned or from getting stuck inside the stacking groove 26 when they fall into it, thus affecting the stable descent of the support plate 27. This ensures that the force on the support plate 27 is always uniform, preventing force deviation that could cause the support plate 27 to get stuck inside the stacking groove 26 and be unable to descend. Thus, the alternating contact between the fixing plates 12 and the two ends of the feeding plate 29 ensures that the support plate 27 is always under uniform force, preventing force deviation that could cause the support plate 27 to get stuck inside the stacking groove 26 and be unable to descend. The end contact mechanism continuously corrects the position of cartons on the feeding plate 29, returning any misaligned cartons to the center position. This prevents cartons from getting stuck in the stacking slot 26 due to misalignment when they fall in, and also ensures that each layer of cartons is aligned, forming a neat stack. This provides a good foundation for subsequent bundling and handling processes, while preventing cartons from getting stuck. This eliminates the need for frequent machine stops to handle abnormalities, keeping the carton stacking process synchronized with the carton output rhythm of the front-end production line, indirectly improving production efficiency.

[0028] Working principle: When using the device, the motor 3 drives the transmission roller 2 to rotate. When the transmission roller 2 rotates, it drives the conveyor belt 1 to rotate. When the conveyor belt 1 rotates, it transports the processed cartons. At the same time, when the conveyor belt 1 rotates, it synchronously drives the driven roller 8 to rotate. When the transmission roller 2 rotates, it synchronously drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, it synchronously drives the fan blade 5 to rotate. When the fan blade 5 rotates, it delivers airflow into the connecting pipe A7. After the airflow enters the connecting pipe A7, the connecting pipe A7 delivers the airflow to the air outlet 30 for discharge. When the driven roller 8 rotates, it will synchronously drive the two sets of reciprocating screws 10 to rotate. When the two sets of reciprocating screws 10 rotate, they will synchronously drive the two sets of sliders 11 to move back and forth alternately outside the reciprocating screws 10. When the two sets of sliders 11 move back and forth alternately, they will synchronously drive the two sets of fixed plates 12 to move back and forth. When the two sets of fixed plates 12 move back and forth alternately, they will drive the two sets of piston rods 14 to move back and forth alternately through the two sets of connecting plates 13. When the two sets of piston rods 14 move back and forth alternately into the piston tube 15, they will continuously squeeze the gas into the connecting tube B16. After the gas enters the connecting tube B16, the connecting tube B16 will transport the gas to the storage tank 17. After the gas enters the storage tank 17, the gas will squeeze the starch-based anti-slip liquid into the connecting tube C19. Since the valve inside the connecting tube C19 is initially closed, the starch-based anti-slip liquid that enters the connecting tube C19 will not enter the spray pipe 20. After the conveyor belt 1 transports the carton into the guide plate 9, the carton will slide down the inclined surface inside the guide plate 9. During the sliding process, the carton will come into contact with the connecting rod 23. After the carton comes into contact with the connecting rod 23, it will push the connecting rod 23 to flip and move inside the empty slot A24. When the carton comes into contact with the connecting rod 23 and causes the connecting rod 23 to flip, the connecting rod 23 will drive the valve rod 21 to rotate synchronously. When the valve rod 21 rotates, the valve rod 21 will open the valve inside the connecting pipe C19. After the valve inside the connecting pipe C19 is opened, the starch-based anti-slip liquid that has entered the connecting pipe C19 will enter the spray pipe 20 through the connecting pipe C19. After the starch-based anti-slip liquid enters the nozzle 20, it will be sprayed outward through multiple sets of nozzles on the outside of the nozzle 20. When the starch-based anti-slip liquid is sprayed out through the nozzles, it will be sprayed on the side of the carton that is in contact with the guide plate 9. As the carton moves, it will gradually move to the outside of the guide plate 9. After the carton moves to the outside of the guide plate 9, because the air outlet 30 is located at the lower end of the guide plate 9, the airflow from the air outlet 30 will promote the rapid drying of the starch-based anti-slip liquid sprayed on the side of the carton. When the carton is completely separated from the guide plate 9, it will fall into the stacking groove 26. After the carton is conveyed into the stacking trough 26, it will fall onto the surface of the feeding plate 29. After the carton falls onto the surface of the feeding plate 29, the weight applied by the feeding plate 29 to the support plate 27 will gradually increase. As the weight of the feeding plate 29 gradually increases, the support plate 27 will gradually descend. As the support plate 27 descends, it will simultaneously compress four sets of springs B28. As the support plate 27 gradually descends, the electrode plate A32 will descend synchronously via the telescopic rod 31. When the electrode plate A32 descends to contact the electrode plate B33, the alarm light 34 will sound an alarm, reminding the staff to replace the feeding plate 29 in time. Since the telescopic rod 31 is telescopic, the feeding plate 29 is not fully loaded when the electrode plate A32 initially contacts the electrode plate B33. As the support plate 27 descends, it will simultaneously compress the telescopic rod 31 to retract, thus allowing the staff time to react when the alarm light 34 alerts them. At the same time, when the two sets of fixed plates 12 move back and forth alternately, they will alternately contact the two ends of the feeding plate 29, thus preventing the cartons on the upper end of the feeding plate 29 from being out of alignment or from getting stuck inside the stacking trough 26 when they fall into it.
