Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to a palletizing device. Background Technology

[0002] In modern industrial production, product conveyor lines are widely used in various fields and are one of the key pieces of equipment for achieving production automation and improving production efficiency. Through continuous material transport, they tightly connect various stages of the production process, greatly promoting the efficient operation of the production flow.

[0003] Most existing product conveyor lines focus only on the straight-line transport of materials between various workstations, lacking effective integration of pallet stacking. At the pallet loading and unloading workstations, manual labor or robotic arms are required to move each pallet, resulting in high efficiency and low cost. Utility Model Content

[0004] The purpose of this invention is to provide a palletizing device that improves the efficiency of product conveying lines and reduces production costs.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] This utility model proposes a palletizing device, comprising:

[0007] A support and a tray moving assembly, wherein the support has an upper tray position and a lower tray position, and the tray moving assembly is located below the support and can slide horizontally between the upper tray position and the lower tray position;

[0008] The loading and unloading tray positions are also provided with a tray lifting assembly and a palletizing support assembly. The palletizing support assembly is movably connected to the bracket. The palletizing support assembly has a first position and a second position. In the first position, the palletizing support assembly is detached from the pallet. In the second position, the palletizing support assembly is at least partially in contact with the lower surface of the pallet. The vertical gap between the palletizing support assembly and the tray lifting assembly is greater than the height of one tray.

[0009] In one embodiment, at least at the loading tray position and the unloading tray position, the bracket has a tray support platform, and when the tray lifting assembly is in the initial position, the top of the tray support platform is flush with the top of the tray lifting assembly.

[0010] In one embodiment, the bracket has a first side and a second side extending in a longitudinal direction, a first support plate is provided adjacent to the first side, and a second support plate is provided adjacent to the second side, the first support plate and the second support plate constituting the tray support platform.

[0011] In one embodiment, the tray lifting assembly includes at least two lifting mechanisms, each including a cylinder and a lifting platform. The lifting platform is fixed to the output end of the cylinder and can move up and down.

[0012] In one embodiment, the palletizing support assembly includes a base and a support member. The base has a first plate and a second plate disposed opposite to each other, with a clearance groove formed between the first plate and the second plate. Bearings are installed on both the first plate and the second plate. The support member is embedded in the clearance groove. The support member is provided with a fixed shaft, with each end of the fixed shaft mounted on one of the bearings. An elastic member is also installed on the side of the support member facing the bracket, and the elastic member is located below the fixed shaft.

[0013] In one embodiment, the tray moving assembly includes a belt conveyor, a slide rail, and a moving component. The moving component is mounted on the slide rail and the belt of the belt conveyor, and the belt conveyor drives the moving component to move horizontally back and forth.

[0014] In one embodiment, the top of the movable component is provided with a positioning pin, which is used to cooperate with the positioning groove on the tray.

[0015] In one embodiment, the slide rails are provided in two directions, extending along the longitudinal direction of the bracket. The bottom of the moving part is provided with a slot and two bases. A slider is provided on the slide rails. The bases are fixed on the sliders. The slots are provided with serrations. Part of the belt of the belt conveyor is fixed in the slots.

[0016] In one embodiment, a clamping assembly is provided at the loading tray and the unloading tray. The clamping assembly includes at least three columns, which are fixed on the bracket. All the columns enclose a stacking accommodating space.

[0017] In one embodiment, a palletizing tray is also included, the top of which is provided with a plurality of positioning posts, and the pallet is also provided with a plurality of positioning slots arrayed on it.

[0018] The technical solution provided by this utility model has the following advantages and effects:

[0019] The material tray moving component drives the material tray to slide horizontally between the upper and lower tray positions. The palletizing support component switches between a first and a second position. The material tray lifting component raises or lowers the pallet. The lifting component, in conjunction with the palletizing support component, separates the material tray from the pallet at the upper tray position and stacks the material tray into the pallet at the lower tray position. This eliminates the need to move each material tray individually to the upper tray position or remove them individually from the lower tray position for palletizing, improving production line efficiency and reducing production costs.

[0041] To achieve automated palletizing on product conveyor lines and improve their efficiency, this invention designs a palletizing device that automatically destacking pallets at the loading position and automatically stacking pallets at the unloading position. Destacking at the loading position refers to removing pallets from a neatly stacked pile of empty or raw material pallets in a specific order and transporting them to a designated location on the production line. Stacking at the unloading position refers to stacking pallets containing finished products after processing or assembly at the unloading position for subsequent centralized storage or transportation. By integrating pallet stacking and destacking on the product conveyor line, the efficiency of the conveyor line can be improved, and the need for manual or robotic arm handling of individual pallets can be eliminated, reducing production costs.

[0042] Figure 1 This is a schematic diagram of the palletizing device used in this embodiment; Figure 2 The diagram shows a palletizing device provided in this embodiment, including a support G10 and a tray moving assembly G20. The support G10 can be part of or part of the entire product conveyor line. The support G10 is rectangular, with an upper tray position G11 and a lower tray position G12 at its two ends. At the upper tray position G11, a first pallet G13, formed by stacking empty or raw material-filled trays, is placed on the support G10; at the lower tray position G12, a second pallet G14, formed by stacking trays containing products, is placed on the support G10. The support G10 is openwork, and the tray moving assembly G20 is located below the support G10 and can slide horizontally between the upper tray position G11 and the lower tray position G12. A tray is unpacked from the first pallet G13 and transported along the support G10 to the processing station via the tray moving assembly G20. The processed product is placed in the tray, and then the tray is transported to the unloading tray position G12 via the tray moving assembly G20, and stacked together with the trays in the second pallet G14 to form a new second pallet G14. It should be noted that although the support G10 between the upper tray position G11 and the lower tray position G12 is straight in this embodiment, it is not limited to this. The support G10 can also have corners or arc bends, which can be set according to the requirements of the product conveyor line.

[0043] like Figure 3 As shown, the material tray G30 in this embodiment is a square tray with a positioning post G31 at each of the four top corners and a groove (not shown) at each of the four bottom corners. The positioning posts G31 and the grooves allow two material trays G30 to be stacked together. It should be noted that the shape of the material tray G30 can also be triangular or polygonal; the specific shape is not limited.

[0044] To enable automatic destacking at the loading pallet position G11 and automatic stacking at the unloading pallet position G12, a pallet lifting assembly G40 and four stacking support assemblies G50 are provided at both positions. The pallet lifting assembly G40 is installed on the inner side of the support G10, between two stacking support assemblies G50. The pallet lifting assembly G40 is used to destacking a pallet G30 from the first stack 11 at the loading pallet position G11; and at the unloading pallet position G12, to stack the pallet G30 together with the pallet G30 in the second stack G14 to form a new second stack G14. The palletizing support assembly G50 is mounted on the bracket G10, and the vertical gap between it and the pallet lifting assembly G40 is greater than the height of one pallet G30. That is, at the unloading position G12, the pallet moving assembly G20 can transport one pallet G30 into the gap between the pallet lifting assembly G40 and the palletizing support assembly G50; and at the loading position G11, the pallet lifting assembly G40 can unload one pallet G30 from the first pallet G13 into the gap between the pallet lifting assembly G40 and the palletizing support assembly G50.

[0045] Specifically, the tray lifting assembly G40 includes two lifting mechanisms G41, which are symmetrically distributed on both sides of the frame 10. Each lifting mechanism G41 includes a cylinder G411 and a lifting platform G412. The lifting platform G412 is plate-shaped and fixed to the output end of the cylinder G411. Driven by the cylinder G411, the lifting platform G412 can move up and down, thereby stacking the trays G30 into the second stack G14 or removing a tray G30 from the first stack G13. Obviously, the tray lifting assembly G40 can also include three lifting mechanisms G41, which are respectively abutted against the three sides of the tray G30, thereby driving the tray G30 to rise or fall at three positions.

[0046] The palletizing support assembly G50 is movably mounted on the frame 10 and has a first position and a second position. In the first position, the palletizing support assembly G50 is disengaged from the first pallet G13 or the second pallet G14. In the second position, the palletizing support assembly G50 at least partially abuts against the lower surface of the first pallet G13 or the second pallet G14. The palletizing support assembly G50 cooperates with the tray lifting assembly G40 to realize the palletizing and depalletizing of the tray G30. Specifically, at the loading tray position G11, the tray lifting component G40 rises, supporting the first stack G13, and the stacking support component G50 is controlled to the first position. Then, the tray lifting component G40 drives the first stack G13 to descend. When the distance the first stack G13 descends is equal to the sum of the height of one tray G30 and the gap distance between two trays G30, the stacking support component G50 is controlled to the second position. At this time, the stacking support component G50 abuts against the lower surface of the second-to-last tray (the direction from the bottom of the stack to the top is the reciprocal direction), preventing the second-to-last tray from descending further. At this time, the first-to-last tray is not restricted, and the tray lifting component G40 continues to descend, driving the first-to-last tray to continue descending, thereby separating one tray G30 from the first stack G13; at the unloading tray... Position G12: The tray moving component G20 moves the tray G30 containing the finished product to the unloading tray position G12. Then, the tray lifting component G40 raises the tray G30 until it engages with the last tray in the second stack G14. At this point, the stacking support component G50 is moved to the first position, and the tray lifting component G40 continues to rise, lifting the second stack G14. When the distance the second stack G14 is raised is equal to the sum of the height of one tray G30 and the gap between the two trays G30, the stacking support component G50 is moved to the second position. At this point, the stacking support component G50 abuts against the lower surface of the last tray, supporting the second stack G14. Then, the tray lifting component G40 descends to the initial position, waiting for the tray moving component G20 to bring the next tray G30.

[0047] like Figure 4As shown, the palletizing support assembly G50 includes a base G51 and a support member G52. Specifically, the base G51 has a first plate G511 and a second plate G512 disposed opposite to each other, with a clearance groove G53 formed between the first plate G511 and the second plate G512. The support member G52 is embedded in the clearance groove G53. Bearings G54 are mounted on both the first plate G511 and the second plate G512. The support member G52 is provided with a fixed shaft G56, which is rotatably connected to the bearings G54. Thus, the support member G52 is rotatably mounted on the base G51, so that the palletizing support assembly G50 has a first position (i.e., the top of the support member is parallel to the horizontal plane) and a second position (i.e., the top of the support member is inclined). An elastic member G55 is also installed on the side of the support member G52 facing the bracket G10, and the elastic member G55 is located below the fixed shaft G56. When the top of the control support G52 is tilted, the elastic element G55 is compressed, and the four palletizing support assemblies G50 are pushed outwards from the bracket G10, allowing the pallet G30 to move up and down without obstruction. When it is necessary to support the first pallet G13 or the second pallet G14, the elastic element G55 returns to its original position, making the top of the support G52 horizontal. The support G52 then abuts against the bottom surface of the first pallet G13 or the second pallet G14, allowing the first pallet G13 or the second pallet G14 to be stably supported on the palletizing support assembly G50. It should be noted that the palletizing support assembly is not limited to the rotating structure of this embodiment; it can also be a sliding structure, such as a sliding structure that can slide inwards and outwards from the bracket.

[0048] like Figure 5 As shown, the material tray moving assembly G20 includes a belt conveyor G21, a slide rail G22, and a moving component G23. The moving component G23 is mounted on the slide rail G22. The belt conveyor G21 can drive the moving component G23 to move horizontally reciprocally. It should be emphasized that the horizontal reciprocating movement is not limited to horizontal linear movement, as long as the material tray G30 can be moved horizontally between the upper tray position G11 and the lower tray position G12. Specifically, there are two slide rails G22 spaced apart, extending along the longitudinal direction of the bracket G10, and sliders G221 are mounted on the slide rails G22. The belt conveyor G21 includes a motor G211, a pulley G212, and a belt G213. The belt conveyor G21 is a conventional device in the art and will not be described in detail here. The bottom of the moving part G23 has two bases G231 and a slot G232. One base G231 is fixed on a slider G221. The slot G232 has serrations, and part of the belt G213 of the belt conveyor G21 is clamped and fixed in the slot G232. The motor G211 drives the pulley G212 to rotate, and the moving part G23 is clamped and fixed on the belt G213. Thus, when the belt G213 moves back and forth, it drives the moving part G23 to move back and forth.

[0049] like Figure 6and Figure 7 As shown, in this embodiment, the top of the moving component G23 is provided with a positioning pin G233, and the middle array of the tray G30 is provided with multiple through slots G32. The positioning pin G233 is inserted into the through slot G32, thereby moving the moving component G23 and driving the tray G30 to move. Obviously, the tray G30 may not have through slots G32, but at least multiple blind holes are provided in the bottom array to form positioning grooves, thereby driving the tray to move through the cooperation of the positioning grooves and the positioning pins. It is preferable to provide multiple through slots / blind holes, which makes controlling the tray moving component 40 simpler and more convenient.

[0050] To ensure smoother and more reliable movement of the pallet during stacking and destacking, this embodiment includes a pallet support platform G60 mounted on the bracket G10. Specifically, the bracket G10 has a first side and a second side extending longitudinally. A first support plate G61 is mounted on the inner side of the first side, and a second support plate G62 is mounted on the inner side of the second side. The first support plate G61 and the second support plate G62 are of the same height, together forming the pallet support platform G60. When the pallet G30 moves, its bottom surface abuts against the first support plate G61 and the second support plate G62. It is easily understood that the first support plate G61 and the second support plate G62 can also be mounted on the outer side of the bracket G10 as needed.

[0051] In some embodiments, when the movable component G23 can stably support the tray G30 and move the tray G30, the tray support platform G60 may not be required. However, since the upper tray position G11 and the lower tray position G12 involve the stacking and destacking of the tray G30, it is preferable to provide the tray support platform G60 at the upper tray position G11 and the lower tray position G12. Furthermore, the top of the tray support platform G60 needs to be flush with the top of the tray lifting assembly G40 in its initial position so that the tray G30 can remain stable in these two positions.

[0052] To ensure the safety and stability of the palletizing, this embodiment also includes clamping components G70 at the loading tray position G11 and the unloading tray position G12. Specifically, the clamping component G70 includes four uprights G71, which are fixed to the bracket G10. All the uprights G71 enclose the palletizing space, and all the uprights G71 limit the palletizing at the four corners. Obviously, the number of uprights G71 is not limited to four; it can also be three, five, etc.

[0053] In summary, in this embodiment, by controlling the palletizing support assembly to switch between a first position and a second position, the pallet lifting assembly drives the pallet and pallet to rise or fall. This, in conjunction with the pallet lifting assembly, enables the unpacking of the pallet from the first pallet at the loading position and the stacking of the pallet into the second pallet at the unloading position. This eliminates the need to move each pallet individually to the loading position or to remove them one by one at the unloading position for palletizing, thus improving production line efficiency and reducing production costs.

[0054] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.

The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of this utility model, and it is not intended to limit the protection scope of this utility model.

[0056] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
