Description

Technical Field

[0001] This invention relates to the field of palletizing equipment technology, specifically a packaging palletizing device and method. Background Technology

[0002] As a basic unit of modern logistics and warehousing, packaging bags play an important role in containing, protecting, and identifying goods. They are especially essential for the safe and efficient transfer of bulk materials in industries such as agriculture, chemicals, and building materials. Depending on the base material, packaging bags can be divided into categories such as plastic film bags, multi-layer paper bags, and woven bags. At the end of the woven bag production line, the finished bags, after being sewn and cut, are continuously sent out. At this point, they must be stacked. To adapt to continuous production, a stacking mechanism is usually integrated at the discharge port, such as using a flipping plate, pneumatic pressure plate, or servo-driven layer stacking device. The stacking mechanism must maintain continuous operation in sync with the production line to ensure that there is no accumulation of bags after discharge, thereby providing an orderly material flow for bundling and pallet stacking.

[0003] However, in actual production, the entire process of stacking woven bags to finished product palletizing still relies heavily on manual labor. Specifically, the stacks of bags continuously output by the stacking mechanism need to be manually removed, counted piece by piece, sorted into fixed quantities, and bundled. Finally, the bundled woven bags are transported and stacked layer by layer on pallets. Because the stacking mechanism must operate continuously to match the bag-making speed, operators need to frequently pick up and sort bags near the moving parts at the discharge port. A slight carelessness may result in limb pinching or entanglement accidents, posing significant safety hazards. At the same time, the stacking, counting, bundling, and palletizing processes are disconnected from each other, requiring multiple workers to work together, resulting in high labor intensity and labor costs. Moreover, manual counting is prone to errors due to fatigue or negligence, leading to inaccurate bundle quantities, which in turn affects the inventory management and customer acceptance of the entire batch of materials. In addition, the pace of manual operation is difficult to synchronize stably with the high-speed production line, often resulting in backlog at the discharge port, bag blockage, or forced speed reduction, which seriously restricts the continuity and efficiency of production.

[0004] Based on this, a packaging palletizing device and method are provided that can eliminate the drawbacks of existing devices. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0030] In one embodiment, such as Figures 1-11 As shown, a packaging and palletizing device includes a feeding component 11 and a bundling component 14. A carrying component 12 is installed between the feeding component 11 and the bundling component 14. The carrying component 12 is used to carry woven bags and achieve continuous feeding. A transfer component 13 is provided above the carrying component 12. The transfer component 13 is used to transfer the stacked woven bags to the bundling component 14, and then bundle the woven bags so that the bundled woven bags can be stacked. The feeding component 11 includes a feeding rack 15. First mounting rollers are symmetrically arranged inside the feeding component 11, and a plurality of first conveyor belts are arrayed between the two first mounting rollers. 16. The unloading rack 15 is provided with a stacking mechanism for stacking woven bags at the end of the first conveyor belt 16. The carrying component 12 includes a switching frame 22. The upper end of the switching frame 22 is symmetrically provided with a material loading mechanism 28. The material loading mechanism 28 is used for stacking woven bags. The stacking mechanism is used to evenly stack the woven bags that are being unloaded and conveyed. The material loading mechanism 28 is used to carry the woven bags. The first bearing 23 can switch between the two material loading mechanisms 28 so that the woven bags can be continuously stacked. The material transfer component 13 can transfer the stacked woven bags to the upper end of the bundling component 14 so that the woven bags can be bundled. The stacking mechanism includes a mounting shaft 21, which is rotatably mounted inside the unloading rack 15. One end of the mounting shaft 21 is connected to the output end of a first driving component, which is installed inside the unloading rack 15. The mounting shaft 21 has an array of positioning slots and a plurality of equally spaced locking seats 20. Each locking seat 20 has a swing rod 19 mounted at its end, with the end of each swing rod 19 being T-shaped. A reinforcing tube is provided between the ends of two swing rods 19. The initial position of each swing rod 19 is tangential to the end of the first conveyor belt 16. A support rod is provided inside the unloading rack 15 at the initial position of the swing rod 19. A pressure roller is fitted onto the upper end of the first conveyor belt 16, and the pressure roller is mounted on the end of a connecting frame. The connecting frames are all hinged. The first fixed frame is fixed to the upper end of the unloading frame 15. The connection between the connecting frame and the first fixed frame is provided with elastic elements. In use, when the woven bags are unloaded after production, the woven bags are conveyed to the upper end of the first conveyor belt 16. The second driving component can drive the first mounting roller to rotate, so that several first conveyor belts 16 rotate simultaneously, thereby conveying the woven bags. After the woven bags are conveyed to the end of the first conveyor belt 16, under the action of the pressure roller, the woven bags are pressed tightly against several swing rods 19. Then, the first driving component drives the mounting shaft 21 to rotate at a fixed angle, so that the mounting shaft 21 drives the woven bags to deflect through the snap-fit ​​seat 20 and the swing rods 19, so that the woven bags are stacked. The snap-fit ​​seat 20 is detachable so that it can be adjusted according to the size of the woven bags.

[0031] The upper end of the unloading rack 15 is fixedly provided with a first mounting frame. The inner side of the first mounting frame is provided with a plurality of infrared counting emitting components 17. The infrared counting emitting components 17 are located above the gap of the first conveyor belt 16.

Both the infrared counting emitting components 17 and the infrared counting receiving components 18 are electrically connected to an external control component. In use, when the woven bag passes between the infrared counting emitting components 17 and the infrared counting receiving components 18, the light emitted by the infrared counting emitting components 17 will be blocked. The infrared counting receiving components 18 will not receive the light source and will then count. When the count reaches the set data, the external control component can control the switching frame 22 to switch the loading mechanism 28, thereby ensuring the consistency of the number of woven bags stacked.

[0032] The bottom end of the switching frame 22 is fixedly provided with a fixed shaft, on which a first bearing 23 is provided. The bottom end of the switching frame 22 is fixedly provided with a fixed ring, on which a second bearing 24 is installed. The first bearing 23 and the second bearing 24 are both installed on a third fixed frame, which is fixedly located inside the bottom end of the base frame 25. The base frame 25 is installed between the feeding component 11 and the bundling component 14. The end of the fixed shaft is connected to the output end of the transmission box 26. The input end of the transmission box 26 is connected to the output end of the first motor 27. The first motor 27 is installed on one side of the transmission box 26, which is installed inside the bottom end of the base frame 25. The first motor 27 is electrically connected to an external control component. In use, when a fixed number of woven bags are stacked inside the loading mechanism 28, the external control component controls the first motor 27 to start. The first motor 27 drives the switching frame 22 to rotate through the transmission box 26 and the fixed shaft. The switching frame 22 switches the loading mechanism 28, thereby ensuring that the woven bags can be continuously stacked.

[0033] The material loading mechanism 28 includes a material loading frame 29, which has an L-shaped cross-section. A plurality of first rotating rollers 30 are arrayed on the inner side of the material loading frame 29. Each of the first rotating rollers 30 has a first retainer rotatably mounted at both ends, and the first retainers are fixedly mounted on the upper end of the material loading frame 29. Each first retainer at one end of the first rotating roller 30 has a mounting groove, within which a limiting roller 31 is fitted. Each limiting roller 31 has a second retainer rotatably mounted at the other end, and the second retainers are fixedly mounted on the upper end of the material loading frame 29. A plurality of first limiting rods 32 are fitted at the other end of each of the first rotating rollers 30. The first limiting rods 32 are positioned in a series of... At the gap between the first rotating roller 30 and the upper end of the material carrier 29 and the position of the limiting roller 31, a limiting groove is provided. Several first limiting rods 32 are fixedly installed on the upper end of the first mounting rod. The first mounting rod is fixedly installed on the upper end of the switching frame 22 by screws. Several adjusting screw holes are arranged in an array at the upper end of the switching frame 22 and the limiting groove. Several first limiting through holes are arranged in an array at the end of the material carrier 29. Second limiting rods 33 are slidably installed in the first limiting through holes. The second limiting rods 33 are fixedly installed on the upper end of the second mounting rod. The second mounting rod is located below the switching frame 22. The upper end of the switching frame 22 and the first limiting through hole are provided with a second limiting through hole.

[0034] The second mounting rod has a limiting slide post fixedly installed at the bottom center. The limiting slide post is slidably installed in the limiting slide groove at the upper end of the support rail 34. The support rail 34 is fixedly installed on the upper end of the switching frame 22. The support rail 34 has a notch at the end of the unloading frame 15. An adjusting rail 35 is provided at the notch. The upper end of the adjusting rail 35 has a limiting slide groove. A sliding plate is symmetrically provided on one side of the adjusting rail 35. A first guide slide rod is slidably installed at the end of each sliding plate. The first guide slide rod is... The adjustment rail 35 is fixedly installed on the upper part of the base frame 25. A drive frame is fixedly installed on the other side of the adjustment rail 35. The other end of the drive frame is fixedly installed at the telescopic end of the first cylinder 36. The first cylinder 36 is fixedly installed at the bottom of the base frame 25. A connecting shaft 52 is fixedly installed at the bottom of the material rack 29. A limiting block is fixedly installed on the connecting shaft 52. A sliding hole is provided at the upper end of the switching frame 22 and the connecting shaft 52. A limiting groove is provided at the upper end of the switching frame 22 and the sliding hole, and the limiting groove is adapted to the limiting block.

[0035] The material carrier 29 has several mounting screw holes arrayed at one end. An adjusting plate is located inside the material carrier 29. The adjusting plate is fixedly connected to the material carrier 29 by screws engaging with the mounting screw holes. In use, the distance between one side of the adjusting plate and the end of the material carrier 29 is selected according to the size of the woven bag, and the adjusting plate is fixed with screws so that the distance between one side of the adjusting plate and one side of the second limiting rod 33 is slightly larger than the width of the woven bag. Based on the length of the woven bag, since the limiting roller 31 is fixed, the position of the first limiting rod 32 is adjusted so that the distance between the limiting roller 31 and the first limiting rod 32 is slightly larger than the length of the woven bag. Then, the first mounting rod is fixed by screws engaging with the adjusting screw holes. When the material carrier 29 rotates to the end of the unloading rack 15, the limiting block and the limiting groove cooperate to further... The material carrier 29 is limited, and then the external control unit controls the extension end of the first cylinder 36 to retract, so that the adjusting rail 35 drives the second mounting rod to move through the limiting slide, so that the end of the second limiting rod 33 is on the same plane as the inner bottom end of the material carrier 29. Then the swing rod 19 works to stack the woven bags on the upper end of the first rotating roller 30. After the number of woven bags is stacked to a fixed number, the external control unit causes the first cylinder 36 to move quickly through the external air source. The extension end of the first cylinder 36 drives the second limiting rod 33 to rise through the adjusting rail 35, so that the upper end of the adjusting rail 35 is on the same plane as the upper end of the support rail 34. The second limiting rod 33, the adjusting plate, the limiting roller 31 and the first limiting rod 32 can limit the woven bags. Then the switching frame 22 can switch the material carrier 29.

[0036] The material transfer component 13 includes a second fixed frame 41, which is L-shaped. A material support frame 40 is fixedly mounted at the bottom of the second fixed frame 41. The material support frame 40 is composed of an array of several material support rods. A pressure plate 47 is fitted inside the second fixed frame 41. The pressure plate 47 is fixedly connected to the telescopic ends of two fourth cylinders 48, which are mounted on the upper end of the second fixed frame 41. Second guide slide rods are fixedly mounted around the pressure plate 47. A connecting seat 42 is fixedly mounted on the upper end of the second fixed frame 41. A connecting pipe 43 is sleeved at the end of the connecting seat 42. An electric cylinder 44 is installed inside the connecting pipe 43, and the telescopic end of the electric cylinder 44 is fixedly connected to the connecting seat 42. The connecting pipe 43 is fixedly mounted on the slide block 45, which is installed on the sliding end of the ball screw linear module 46. The slide block 45 is installed on the upper inner side of the outer frame, which is fixedly mounted on the outer side of the switching frame 22. A second motor 37 is provided inside the base frame 25 at the end of the connecting shaft 52 away from the end of the unloading rack 15. A mounting shell is fixedly mounted on the outer side of the second motor 37, and support frames 38 are symmetrically provided on the mounting shell. The ends of the support frames 38 are fixedly connected to the telescopic ends of the third cylinder 39. The third cylinder 39 is fixedly mounted at the bottom inside the base frame 25. In use, when the material carrier 29 carrying stacked woven bags rotates to the end away from the unloading rack 15, the outer control component controls the third cylinder 39. Upon startup, the extension end of the third cylinder 39 drives the second motor 37 to rise via the support frame 38. The output end of the second motor 37 is inserted into the mating groove at the end of the connecting shaft 52. Subsequently, the mounting shell pushes the material carrier 29 to rise via the connecting shaft 52, so that the ends of the first limit rod 32 and the second limit rod 33 are both at the bottom of the material carrier 29. Then, the external control component controls the second motor 37 to start, and the output end of the second motor 37 drives the material carrier 29 to rotate 90 degrees, so that the limit roller 31 is close to the end of the unloading frame 15. Then, the external control component controls the electric cylinder 44 to start, and the extension end of the electric cylinder 44 drives the second fixed frame 41 and the material support frame 40 to descend, so that the upper end of the material support rod is lower than the highest point of the first rotating roller 30. The external control component controls... When the ball screw linear module 46 is activated, the moving end of the ball screw linear module 46 drives the second fixed frame 41 to move through the slide 45 and the connecting pipe 43, so that the material support frame 40 is located inside the material carrier 29 and the material support rod is located in the gap between the first rotating rollers 30. The external control component controls the second motor 37 and the third cylinder 39 to reset, so that the material carrier 29 is reset, the woven bag is separated from the first rotating roller 30, and the material support frame 40 can support the woven bag. Then the fourth cylinder 48 is activated, and the extension end of the fourth cylinder 48 drives the pressure plate 47 to move, so that the pressure plate 47 presses the woven bag tightly. The ball screw linear module 46 drives the woven bag to move to the bundling component 14, so that the bundling component 14 bundles the stacked woven bags.

[0037] The bundling component 14 includes a mounting box 49, which is installed on one side of the base frame 25. A second conveyor belt 50 is located inside the mounting box 49, and several second mounting rollers are located on the inner side of the second conveyor belt 50. All second mounting rollers are located inside the mounting box 49. A third driving component is located inside the mounting box 49, and a binding component 51 is located inside the mounting box 49. Clearance grooves are provided on the outer side of the second conveyor belt 50 and at the material support rod. In use, when the material support frame 40 moves the woven bag to the end of the second conveyor belt 50, the material support frame 40 descends, causing the material support rod to be located within the clearance groove. At this time, the woven bag is located at the upper end of the second conveyor belt 50. Subsequently, the third driving component cooperates with the second mounting rollers to transport the woven bag. When the woven bag moves to the inner side of the binding component 51, the binding component 51 can bind the stacked woven bags multiple times. After binding, the second conveyor belt 50 continues to transport the bound woven bags. Example 2

[0038] The difference from Embodiment 1 is that the mounting box 49 is provided with a roller conveyor at its end, and an external stacking component and a pallet are provided on one side of the roller conveyor. In use, after the binding component 51 has finished binding the woven bag, the second conveyor belt 50 transfers the bound woven bag to the roller conveyor. The roller conveyor can transport the bound woven bag, and then the external stacking component stacks the bound woven bag to the top of the pallet. It is worth noting that the roller conveyor and the external stacking component in this application adopt existing structures and are not shown in the figure. The specific model can be selected according to the actual production and will not be described in detail here.

[0039] The above embodiment discloses a packaging and palletizing device. When the woven bags are finished being produced and unloaded, an external control unit starts the first motor 27. The first motor 27 drives the switching frame 22 to rotate via the transmission box 26 and the fixed shaft. When the material carrier 29 rotates to the end of the unloading frame 15, it is limited by the cooperation of the limiting block and the limiting groove. Subsequently, the external control unit controls the extension end of the first cylinder 36 to retract, causing the adjusting track 35 to move the second mounting rod via the limiting slide column. This makes the end of the second limiting rod 33 and the inner bottom end of the material carrier 29 lie on the same plane, and the woven bags are conveyed to... At the upper end of the first conveyor belt 16, the second driving component can drive the first mounting roller to rotate, so that several first conveyor belts 16 rotate simultaneously, thereby conveying the woven bags. After the woven bags are conveyed to the end of the first conveyor belt 16, under the action of the pressure roller, the woven bags are pressed tightly against several swing rods 19. Then, the first driving component drives the mounting shaft 21 to rotate at a fixed angle, so that the mounting shaft 21 drives the woven bags to deflect through the snap-fit ​​seat 20 and the swing rods 19, stacking the woven bags on the upper end of the first rotating roller 30. At the same time, the infrared counting emitting component 17 and the infrared counting receiving component 18 cooperate to count the woven bags. After a fixed number of woven bags are stacked, the external control component causes the first cylinder 36 to move rapidly through an external air source. The extension end of the first cylinder 36 drives the second limit rod 33 to rise through the adjustment rail 35, so that the upper end of the adjustment rail 35 and the upper end of the support rail 34 are on the same plane. The second limit rod 33, the adjustment plate, the limit roller 31 and the first limit rod 32 can limit the woven bags. Then the switching frame 22 can switch the material carrier 29. After the material carrier 29 carrying the stacked woven bags rotates to the end away from the unloading rack 15, the external control component controls the third cylinder 39 to start. The telescopic end of the third cylinder 39 drives the second motor 37 to rise through the support frame 38. The output end of the second motor 37 is inserted into the docking groove at the end of the connecting shaft 52. Then, the mounting shell pushes the material carrier 29 to rise through the connecting shaft 52, so that the ends of the first limit rod 32 and the second limit rod 33 are both at the bottom of the material carrier 29. Then, the external control component controls the second motor 37 to start. The output end of the second motor 37 drives the material carrier 29 to rotate 90 degrees, so that the limit roller 31 is close to the end of the unloading rack 15. Then, the external control component controls the electric cylinder 44 to start. The telescopic end of the electric cylinder 44 drives the second motor 39 to rotate 90 degrees. The second fixed frame 41 and the material support frame 40 are lowered, so that the upper end of the material support rod is lower than the highest point of the first rotating roller 30. The external control component controls the ball screw linear module 46 to start. The moving end of the ball screw linear module 46 drives the second fixed frame 41 to move through the slide 45 and the connecting pipe 43, so that the material support frame 40 is located inside the material carrier 29 and the material support rod is located in the gap between the first rotating rollers 30. The external control component controls the second motor 37 and the third cylinder 39 to reset, so that the material carrier 29 is reset, the woven bag is separated from the first rotating roller 30, and the material support frame 40 can lift the woven bag. Then the fourth cylinder 48 is started. The extension end of the fourth cylinder 48 drives the pressure plate 47 to move, so that the pressure plate 47 presses the woven bag tightly. After the material support frame 40 moves the woven bag to the end of the second conveyor belt 50, the material support frame 40 descends, so that the material support rod is located in the clearance groove. At this time, the woven bag is located at the upper end of the second conveyor belt 50. Then, the third drive component cooperates with the second mounting roller to transport the woven bag. When the woven bag moves to the inside of the binding component 51, the binding component 51 can bind the stacked woven bags multiple times. After binding, the second conveyor belt 50 transfers the bound woven bag to the roller conveyor component. The roller conveyor component can transport the bound woven bag. Then, the external stacking component stacks the bound woven bag to the top of the pallet.
