Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging equipment technology, specifically to an automatic sorting and palletizing device for strip packages. Background Technology

[0002] In the downstream packaging production lines of food, pharmaceuticals, and daily chemicals, after the multi-row packaging machine outputs strip-shaped small bags, these strips need to be arranged neatly and stacked to form layered packaging before being boxed or bagged. To ensure stacking stability and prevent interlayer adhesion and compression damage, partition paper must be placed between each layer of strips for isolation and support.

[0003] The following technical defects are currently prevalent in the industry: The sorting, partitioning, and stacking of parcels largely rely on manual labor, resulting in high labor costs, low efficiency, and high production costs. Furthermore, issues such as uneven parcel arrangement, misaligned partitions, and product damage are prone to occur.

[0004] Existing automated stacking devices mostly adopt external partition conveyor structures, resulting in a large overall size of the equipment. Especially when there are many rows of strip package outlets, they occupy a huge amount of factory space, making layout difficult and equipment investment costs high.

[0005] Some automated equipment uses rotary cylinders in conjunction with suction cups to pick up and feed the paper dividers. The structure is complex and there are many moving parts. It is prone to malfunctions such as unstable paper picking, paper feeding deviation, and paper jams. The maintenance difficulty and operating cost are relatively high.

[0006] The existing equipment has poor compatibility, and the slot width and partition tray spacing are not adjustable, making it difficult to quickly adapt to different sizes of strip packs and partition paper. The changeover time is long and the versatility is insufficient.

[0007] When the gathering device returns, it can easily cause the strips to shift, resulting in skewed stacking and affecting the accuracy of subsequent boxing and the appearance quality of the product.

[0008] Existing technologies, such as the linear stacking device for conveying strip packages disclosed in application number CN201911291080.X, although achieving some automation functions, still adopt an external and decentralized structure, with a large overall footprint and low integration, which cannot meet the needs of modern production lines for compactness, high versatility, high stability, and low cost of operation and maintenance. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides an automatic packing and palletizing device, which aims to automate the entire process of pack conveying, sorting, palletizing, and automatic placement of dividers, while reducing the equipment's floor space.

[0010] To achieve the above objectives, the present invention provides the following technical solution: An automatic sorting and palletizing device for strip packages includes a frame, a partition mechanism, a stacking and lifting mechanism, and a gathering device. The partition mechanism, stacking and lifting mechanism, and gathering device are all fixedly installed on the frame. The partition mechanism is located above and to the side of the stacking and lifting mechanism, and the gathering device is located on the feeding side of the stacking and lifting mechanism and is arranged perpendicular to the stacking and lifting mechanism.

The scraper is horizontally installed above the partition paper conveyor belt and is in contact with the upper surface of the partition paper conveyor belt. The cylinder is horizontally fixed on the frame outside the output end of the partition paper conveyor belt. The first partition paper pusher and the second partition paper pusher are fixedly connected side by side to the piston rod end of the cylinder and can push linearly in the horizontal direction.

[0011] As a further embodiment of the present invention, the partition paper conveyor belt is equipped with a drive shaft, a driven shaft, an adjusting shaft, bearings, a first drive wheel, a second drive wheel, a first driven wheel, a second driven wheel, a third driven wheel, and a fourth driven wheel. The drive shaft, driven shaft, and adjusting shaft are parallel to each other and are all rotatably mounted on the frame via bearings. The drive shaft is located at the input end of the partition paper conveyor belt, the driven shaft is located at the output end of the partition paper conveyor belt, and the adjusting shaft is located below the drive shaft and the driven shaft and is used to tension and adjust the partition paper conveyor belt. The first drive wheel and the second drive wheel are coaxially fixedly mounted on the drive shaft, the first driven wheel and the second driven wheel are coaxially fixedly mounted on the driven shaft, and the third driven wheel and the fourth driven wheel are coaxially fixedly mounted on the adjusting shaft. The first drive wheel, the second drive wheel, the first driven wheel, the second driven wheel, the third driven wheel, and the fourth driven wheel are all meshed and connected to the inner side of the partition paper conveyor belt.

[0012] As a further embodiment of the present invention, the stacking lifting mechanism includes a ball screw, a strip package slot, a limiting baffle, a slot width adjustment handle, a screw mounting base, a lifting slider, and a guide column; the ball screw is arranged vertically and fixed to the frame through the screw mounting base; the guide column is arranged parallel to the ball screw and fixed to the frame; the lifting slider is fixedly connected to the nut of the ball screw and slides in cooperation with the guide column; the strip package slot is horizontally fixedly installed on the lifting slider and moves up and down with the lifting slider; the limiting baffle is vertically fixed to the outside of the discharge end of the strip package slot; the slot width adjustment handle is rotatably installed on the side of the strip package slot and is drivenly connected to the width adjustment screw inside the strip package slot.

[0013] As a further embodiment of the present invention, the device further includes a first conveyor belt, a second conveyor belt, a conveyor belt support, a conveyor belt drive motor, a conveyor belt drive roller, and a conveyor belt driven roller. The first conveyor belt and the second conveyor belt are installed parallel to each other on the conveyor belt support. The conveyor belt support is fixed on the frame and located on the feeding side of the gathering device. The conveyor belt drive roller and the conveyor belt driven roller are rotatably installed at both ends of the conveyor belt support. The first conveyor belt and the second conveyor belt are respectively fitted onto the corresponding conveyor belt drive roller and conveyor belt driven roller. The conveyor belt drive motor is connected to the conveyor belt drive roller. The discharge ports of the first conveyor belt and the second conveyor belt are aligned and connected with the pushing inlet of the gathering device.

[0014] As a further embodiment of the present invention, the gathering device includes a gathering push plate, a gathering drive cylinder, a gathering guide rail, and a gathering slider; the gathering guide rail is horizontally fixed on the frame, the gathering slider is slidably engaged with the gathering guide rail, the gathering push plate is vertically fixed on the gathering slider, the gathering drive cylinder is horizontally mounted on the frame and the piston rod is fixedly connected to the gathering push plate; the pushing direction of the gathering push plate is perpendicular to the pushing direction of the first and second partition paper pushers, the gathering push plate pushes the strip package laterally into the strip package slot, and the first and second partition paper pushers push the partition paper longitudinally to the top of the strip package inside the strip package slot.

[0015] As a further embodiment of the present invention, tray one and tray two are symmetrically arranged along the width direction of the partition paper conveyor belt. A width adjustment groove and a locking bolt are provided between tray one, tray two and the frame. The distance between them can be adjusted left and right along the width adjustment groove. After the partition paper falls from the card issuing machine, it is supported and positioned by tray one and tray two, and then conveyed forward by the partition paper conveyor belt and the scraper.

[0016] As a further embodiment of the present invention, when the strip package slot descends to the low position, the upper surface of the slot is flush with the upper surface of the output end of the partition paper conveyor belt, so that the partition paper can be smoothly pushed into the top of the strip package; when the strip package slot rises to the high position, the upper surface of the slot is flush with the pushing height of the gathering device, so that the strip package can be smoothly pushed in and neatly arranged by the limiting baffle.

[0017] As a further embodiment of the present invention, the partition paper conveyor belt, cylinder, partition paper pusher one, partition paper pusher two, gathering device, stacking lifting mechanism, conveyor belt one, and conveyor belt two are linked and coordinated in sequence to complete the fully automatic cycle of strip pack conveying, strip pack sorting and slotting, slot descent, partition paper pushing, double layer stacking, lifting and avoiding, and whole stack output.

[0018] Compared with the prior art, the present invention has the following outstanding substantive features and significant progress: This invention integrates the partition mechanism, the stacking and lifting mechanism, and the gathering device into the same frame, and creatively positions the partition mechanism above and to the side of the stacking and lifting mechanism, eliminating the need for an external rotary suction structure. This compact layout significantly reduces the equipment's footprint, making it particularly suitable for production environments with limited factory space.

[0019] This invention abandons the complex suction cup rotation method and adopts a direct pushing scheme using cylinder-driven dual pushers to push the separator paper side by side. This design simplifies the transmission chain, eliminates the need for a vacuum generator and complex timing control, not only reducing manufacturing costs but also improving the stability and cycle efficiency of separator paper pushing.

[0020] The present invention features an adjustable strip pack slot width, an adjustable distance between tray one and tray two, and a parallel double pusher structure for the pusher. When the specifications of the strip pack or partition paper change, only the width needs to be adjusted via the handle to adapt, without the need to replace any parts. This design is not affected by the number of export columns, and can quickly adapt to different packaging specifications, significantly improving the versatility and flexible production capacity of the equipment.

[0021] This invention achieves independent control of the lateral pushing of the strip package and the longitudinal pushing of the partition paper through the vertical layout of the gathering device and the stacking lifting mechanism. Combined with the lifting and avoidance action of the strip package slot, it effectively avoids the problem of strip package displacement during the return stroke of the sorting device, ensuring the regularity of double-layer stacking and product quality.

[0025] 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. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to embodiments.

[0027] Example 1: like Figures 1 to 4 As shown, this embodiment provides an automatic sorting and palletizing device for parcels, including a frame 1, a partition mechanism 2, a stacking and lifting mechanism 3, and a gathering device 4. The frame 1 serves as the supporting foundation for the entire device and is constructed using welded steel profiles or aluminum alloy profiles, providing sufficient rigidity and a suitable mounting surface. The partition mechanism 2, the stacking and lifting mechanism 3, and the gathering device 4 are all fixedly mounted on the frame 1 using bolts or welding.

[0028] The partition mechanism 2 is located above and to the side of the stacking and lifting mechanism 3, specifically above and slightly behind the initial position of the strip pack slot 28 in the stacking and lifting mechanism 3. This facilitates the horizontal pushing of the partition paper by the partition paper pusher 1 8 and the partition paper pusher 2 9 into the strip pack slot 28. The gathering device 4 is located on the feeding side of the stacking and lifting mechanism 3, i.e., the front side of the frame 1. The gathering device 4 is arranged perpendicular to the stacking and lifting mechanism 3. The pushing direction of the gathering device 4 is perpendicular to the pushing direction of the partition paper pusher 1 8 and the partition paper pusher 2 9, forming an L-shaped feeding and partition paper path to avoid interference between actions.

[0029] The partition mechanism 2 includes a card dispenser 5, a partition paper conveyor belt 6, a cylinder 7, a partition paper pusher 1 8, a partition paper pusher 2 9, a scraper 10, a tray 1 11, and a tray 2 12. The card dispenser 5 is vertically installed directly above the partition paper conveyor belt 6, with its discharge port facing the input end of the partition paper conveyor belt 6. The tray 1 11 and tray 2 12 are respectively fixed on the left and right sides of the partition paper conveyor belt 6 in the width direction and are located below the discharge port of the card dispenser 5, used to receive the partition paper falling from the card dispenser 5. The tray 1 11 and tray 2 12 are symmetrically arranged along the width direction of the partition paper conveyor belt 6. A width adjustment groove and locking bolt are provided between the tray 1 11, tray 2 12 and the frame 1. The distance between them can be adjusted left and right along the width adjustment groove to accommodate partition paper of different widths.

[0030] A scraper 10 is mounted horizontally above the partition paper conveyor belt 6 and fixed to the frame 1 by a bracket. The lower edge of the scraper 10 is in contact with the upper surface of the partition paper conveyor belt 6, providing slight damping as the partition paper is driven forward by the conveyor belt to prevent it from sliding due to inertia or static electricity. It also separates potentially overlapping partition papers, ensuring that the partition papers are conveyed forward in a single, neat sheet. A cylinder 7 is horizontally fixed to the frame 1 outside the output end of the partition paper conveyor belt 6, with its piston rod facing the stacking lifting mechanism 3. Partition paper pusher 1 8 and partition paper pusher 2 9 are fixedly connected side-by-side to the piston rod end of the cylinder 7. Both partition paper pusher 1 8 and partition paper pusher 2 9 are L-shaped bent plates, with their vertical section roots fixedly connected to the piston rod end of the cylinder 7 via a connecting plate, and their horizontal section ends forming a flat pushing surface. The distance between the two pushers is adapted to the width of the partition paper. During pushing, both push surfaces simultaneously contact the same edge of the partition paper, achieving smooth, straight-line pushing without deviation. Both can push the partition paper in a straight horizontal direction as the piston rod extends and retracts.

[0031] The drive structure of the partition paper conveyor belt 6 is as follows: The partition paper conveyor belt 6 is equipped with a drive shaft 15, a driven shaft 19, an adjusting shaft 20, a bearing 16, a first driving wheel 17, a second driving wheel 18, a first driven wheel 21, a second driven wheel 22, a third driven wheel 23, and a fourth driven wheel 24. The drive shaft 15, driven shaft 19, and adjusting shaft 20 are parallel to each other and are all rotatably mounted on the frame 1 via the bearing 16. The drive shaft 15 is located at the input end of the partition paper conveyor belt 6 and is driven to rotate by an external motor (not shown in the figure). The driven shaft 19 is located at the output end of the partition paper conveyor belt 6. The adjusting shaft 20 is located below the drive shaft 15 and the driven shaft 19 and is used to tension and adjust the partition paper conveyor belt 6 to prevent slippage during operation. Driven pulley 17 and driven pulley 28 are coaxially fixedly mounted on drive shaft 15, driven pulley 11 and driven pulley 22 are coaxially fixedly mounted on driven shaft 19, and driven pulley 3 and driven pulley 4 are coaxially fixedly mounted on adjusting shaft 20. Driven pulley 17, driven pulley 28, driven pulley 11, driven pulley 22, driven pulley 3, and driven pulley 4 are all synchronous belt pulleys or toothed pulleys, which mesh with the inner side of the partition paper conveyor belt 6 to ensure conveying accuracy.

[0032] The stacking lifting mechanism 3 includes a ball screw 27, a strip package slot 28, a limit baffle 26, a slot width adjustment handle 25, a screw mounting base, a lifting slider, and a guide column. The ball screw 27 is vertically arranged, and its upper and lower ends are fixed to the frame 1 via the screw mounting base. The input end of the ball screw 27 is connected to a servo motor (not shown in the figure). The guide column is arranged parallel to the ball screw 27 and is fixed to the frame 1 via a linear bearing or sliding bushing. The lifting slider is fixedly connected to the nut of the ball screw 27 and slides with the guide column, moving smoothly vertically under the drive of the ball screw 27. The strip package slot 28 is horizontally fixedly installed on the lifting slider and moves up and down with the lifting slider. The strip package slot 28 has a U-shaped or C-shaped slot structure, and its internal width can be adjusted via the slot width adjustment handle 25. The slot width adjustment handle 25 is rotatably mounted on the side of the strip bag slot 28 and is connected to the width adjustment screw inside the strip bag slot 28. Rotating the handle changes the internal width of the strip bag slot 28 to accommodate strip bags of different sizes. The limiting baffle 26 is vertically fixed on the outside of the discharge end of the strip bag slot 28 to prevent the strip bags from exceeding the edge of the slot when pushed out, ensuring that the strip bags are neatly arranged in the slot.

[0033] When the strip package slot 28 descends to its low position, the upper surface of the slot is level with the upper surface of the output end of the partition paper conveyor belt 6. At this time, the partition paper pusher 1 8 and partition paper pusher 2 9 can smoothly push the partition paper into the top of the strip package. When the strip package slot 28 rises to its high position, the upper surface of the slot is level with the pushing height of the gathering device 4. At this time, the gathering device 4 pushes the strip package into the strip package slot 28, and the limiting baffle 26 limits and arranges them neatly.

[0034] This device also includes conveyor belt 13, conveyor belt 2 14, conveyor belt support, conveyor belt drive motor, conveyor belt drive roller, and conveyor belt driven roller. Conveyor belt 13 and conveyor belt 2 14 are installed parallel to each other on the conveyor belt support, forming a dual-channel feeding structure. The conveyor belt support is fixed on the frame 1 and located on the feeding side of the gathering device 4. The conveyor belt drive roller and conveyor belt driven roller are rotatably installed at both ends of the conveyor belt support, and conveyor belt 13 and conveyor belt 2 14 are respectively fitted onto the corresponding conveyor belt drive roller and conveyor belt driven roller. The conveyor belt drive motor is connected to the conveyor belt drive roller to drive the two conveyor belts to run synchronously. The discharge ports of conveyor belt 13 and conveyor belt 2 14 are aligned and connected with the push inlet of the gathering device 4, so that the strip package directly enters the pushing range of the gathering device 4 from the end of the conveyor belt. The gathering device 4 includes a gathering push plate, a gathering drive cylinder, a gathering guide rail, and a gathering slider. The gathering guide rail is horizontally fixed on the frame 1, the gathering slider slides in cooperation with the gathering guide rail, and the gathering push plate is vertically fixed on the gathering slider. The gathering drive cylinder is horizontally mounted on the frame 1, and its piston rod extension is fixedly connected to the gathering push plate. The pushing direction of the gathering push plate is perpendicular to the pushing direction of the partition paper pusher 8 and the partition paper pusher 9. The gathering push plate pushes the strip laterally into the strip pack slot 28, and the partition paper pusher 8 and the partition paper pusher 9 push the partition paper longitudinally to the top of the strip pack inside the strip pack slot 28.

[0035] The work process is as follows: After the equipment starts, the strips are fed into conveyor belt 13 and conveyor belt 2 14 by the upstream equipment. The two conveyor belts run synchronously, transporting the strips to the feed side of the gathering device 4. The gathering drive cylinder pushes the gathering push plate, pushing the strips laterally into the strip slot 28. The limiting baffle 26 ensures that the strips are arranged neatly.

[0036] In single-layer palletizing mode, after the first layer of strip packages is pushed into the strip package slot 28 and into place, there is no need to place the partition paper or push the second layer. The gathering device 4 returns directly to the initial position, the stacking lifting mechanism 3 remains at the high position, and then the external pushing mechanism pushes the single layer of strip packages in the strip package slot 28 directly to the next station to complete the single-layer palletizing.

[0037] In double-layer palletizing mode, after the first layer of packages is pushed into the package slot 28, the ball screw 27 drives the package slot 28 to descend to its lowest position, making the upper surface of the package flush with the upper surface of the output end of the separator paper conveyor belt 6. At this time, the card dispenser 5 issues separator paper, which falls onto tray 11 and tray 22 and then onto the input end of the separator paper conveyor belt 6. The separator paper conveyor belt 6 runs under the drive of the drive shaft 15. The retracting pusher is a vertical flat plate with a smooth and flat surface facing the package. The height of the pusher is greater than the maximum height of the package, and the width is greater than the total width of the package pushed in a single push, to ensure that the package is evenly stressed during the push process and does not tip over or shift. The retracting pusher is vertically fixed on the retracting slider. The cylinder 7 extends, driving the separator paper pusher 1 8 and separator paper pusher 2 9 to move synchronously, smoothly pushing the separator paper into the package slot 28, covering the first layer of packages. Subsequently, the strip package slot 28 rises to its highest position, and the gathering device 4 actuates again, pushing the second strip package into the slot 28 and onto the partition paper. Then, the strip package slot 28 descends again to prevent the strip package from shifting when the gathering device 4 returns. Finally, the strip package slot 28 rises back to its highest position, and the external pushing mechanism pushes the double-layer strip package along with the partition paper to the next station.

[0038] The above actions are controlled by a PLC or industrial computer according to a set time sequence. The partition paper conveyor belt 6, cylinder 7, gathering device 4, stacking lifting mechanism 3, conveyor belt 13, and conveyor belt 2 14 work together to complete the fully automatic cycle of strip pack conveying, strip pack sorting and slotting, slot descent, partition paper pushing, double layer stacking, lifting and avoiding, and whole stack output.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
