[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In order to reduce the layout space of the loading and unloading device and make effective use of space, this application relates to a loading and unloading device that can meet the loading and unloading requirements while also making effective use of space.

[0023] In some embodiments of this application, see Figures 1 to 8 It describes the structure of the loading and unloading device.

[0024] The loading and unloading device includes an upper conveyor line 100, a tray unpacking mechanism 200, a positioning mechanism 300, a first lifting mechanism 400, a handling mechanism 500, a second lifting mechanism 700, and a lower conveyor line 800.

[0025] For ease of arrangement, the loading and unloading device may also include a base (not shown), the fixed platform 600 and the upper conveyor line 100 are fixed to the base, the unloading mechanism 200 and the first lifting mechanism 400 are fixed to the fixed seat of the upper conveyor line 100, and the positioning mechanism 300 and the handling mechanism 500 are fixed to the fixed platform 600 (see [reference]). Figure 1 ).

[0026] In some embodiments of this application, see Figure 1 and Figure 5 The upper conveyor line 100 and the lower conveyor line 800 are arranged vertically, and their conveying directions are parallel.

[0027] The upper conveyor line 100 and the lower conveyor line 800 respectively convey the material trays by means of belts mounted on their fixed seats.

[0028] For circulating conveyor trays, see Figure 1 and Figure 2 The system is equipped with a tray removal mechanism 200, which can remove one tray at a time from a stack of trays stacked on top of each other and place it on the upper conveyor line 100 for conveying. After one tray is conveyed away, the tray removal mechanism 200 is used to remove another tray, and so on, avoiding the tedious operation of manually placing each tray on the upper conveyor line 100, thus improving the level of automation and efficiency of loading and unloading.

[0029] In some embodiments of this application, see Figure 2 and Figure 5 The tray removal mechanism 200 includes a first side support unit 210, a second side support unit 220 and a third lifting mechanism 230. The third lifting mechanism 230 can be vertically lifted and lowered along the conveying direction perpendicular to the upper conveyor line 100, and a top tray (not shown) is provided on its top.

[0030] See also Figure 2 The first side support unit 210 and the second side support unit 220 are arranged opposite each other along the conveying direction of the upper conveyor line 100.

[0031] The top tray of the third lifting mechanism 230 is raised to the highest preset position, which is lower than the positions of the first side support unit 210 and the second side support unit 220. This makes the height difference between the two (the height direction is the lifting direction of the third lifting mechanism 230) exactly the thickness of a tray. Therefore, when a stack of trays is placed on the top tray, the bottom tray of the stack can be left on the top tray, while the first side support unit 210 and the second side support unit 220 can support the remaining trays except for the bottom tray, thus realizing tray unpacking.

[0032] In this way, the tray disassembly mechanism 200 can be used to continuously place trays onto the upper conveyor line 100.

[0033] In some embodiments of this application, the first side support unit 210 and the second side support unit 220 have the same structure. The side support unit includes a support telescopic cylinder and a support part, which is connected to the cylinder rod of the support telescopic cylinder.

[0034] The support telescopic cylinder is arranged on the fixed seat of the upper conveyor line 100. For ease of description, the support telescopic cylinder of the first side support unit 210 is referred to as the first support telescopic cylinder 211, the support part of the first side support unit 210 is referred to as the first support part 212, the support telescopic cylinder of the second side support unit 220 is referred to as the second support telescopic cylinder, and the support part of the second side support unit 220 is referred to as the second support part.

[0035] When the cylinder rods of the first supporting telescopic cylinder 211 and the second supporting telescopic cylinder both extend and approach each other, the first supporting part 212 and the second supporting part extend and approach each other to support the material tray P1. When the cylinder rods of the first supporting telescopic cylinder 211 and the second supporting telescopic cylinder both retract and move away from each other, the first supporting part 212 and the second supporting part retract and move away from each other to release the material tray P1.

[0036] The working principle of the dismantling mechanism 200 is described as follows: (1) The cylinder rods of the first supporting telescopic cylinder 211 and the second supporting telescopic cylinder extend and approach each other, and the first supporting part 212 and the second supporting part extend and approach each other to support a stack of material trays; (2) The third lifting mechanism 230 lifts to the highest preset position; (3) The cylinder rods of the first supporting telescopic cylinder 211 and the second supporting telescopic cylinder retract and move away from each other, and the first supporting part 212 and the second supporting part retract and move away from each other, releasing the material trays to the third lifting mechanism. On the top tray of 230; (4) The cylinder rod of the first supporting telescopic cylinder 211 and the cylinder rod of the second supporting telescopic cylinder extend closer to each other again, and the first supporting part 212 and the second supporting part extend closer to each other, just supporting the remaining trays except for the bottom tray in a stack of trays; (5) The third lifting mechanism 230 descends, so that its top tray is lower than the conveying surface of the upper conveyor line 100. At this time, the bottom tray is supported by the upper conveyor line 100; (6) When the upper conveyor line 100 works, it will convey the trays on it.

[0037] This process is repeated, with the upper conveyor line continuously conveying the material trays 100 times a cycle.

[0038] In some embodiments of this application, as the upper conveyor line 100 (along...) Figure 1 When conveying the material tray P1 to the first position (in the direction indicated by the dashed arrow), see [further details]. Figure 3 , Figures 5 to 6 The first lifting mechanism 400 lifts the material tray P1 on it and it is positioned and held by the positioning mechanism 300 (see...). Figure 6 ), used for loading and unloading materials.

[0039] The first lifting mechanism 400 is fixedly installed on the fixed seat of the upper conveyor line 100, and is located in front of the dismantling mechanism 200 along the conveying direction of the upper conveyor line 100.

[0040] In some embodiments of this application, see Figure 3 The positioning mechanism 300 includes two positioning units (referred to as the first positioning unit 310 and the second positioning unit 320) arranged diagonally. Each positioning unit includes a positioning telescopic cylinder and a positioning support, which is connected to the positioning telescopic cylinder.

[0041] The positioning telescopic cylinder is mounted on a fixed platform 600. For ease of description, see [link to documentation]. Figure 4 The positioning telescopic cylinder of the first positioning unit 310 is referred to as the first positioning telescopic cylinder 311, the positioning support part of the first positioning unit 310 is referred to as the first positioning support part 312, the positioning telescopic cylinder of the second positioning unit 320 is referred to as the second positioning telescopic cylinder, and the positioning support part of the second positioning unit is referred to as the second positioning support part.

[0042] When the cylinder rods of the first positioning telescopic cylinder 311 and the second positioning telescopic cylinder both extend and approach each other, the first positioning support part 312 and the second positioning support part extend and approach each other to support the material tray P1. When the cylinder rods of the first positioning telescopic cylinder 311 and the second positioning telescopic cylinder both retract and move away from each other, the first positioning support part 312 and the second positioning support part retract and move away from each other to release the material tray P1.

[0043] With the upper conveyor line 100 (along) Figure 1 When the conveyor tray P1 is moved to the first position (in the direction indicated by the dashed arrow), the first lifting mechanism 400 operates, and its top tray lifts the tray P1 (at this time, the cylinder rods of the first positioning telescopic cylinder 311 and the second positioning telescopic cylinder should both retract away from each other). When the top tray is lifted to a position higher than the support surface of the corresponding positioning support, the lifting stops. At this time, the cylinder rods of the first positioning telescopic cylinder 311 and the second positioning telescopic cylinder extend closer to each other, causing the first positioning support 312 and the second positioning support to extend closer to each other to support the tray P1. In this way, the tray P1 is held on the first positioning support 312 and the second positioning support (see...). Figure 3 and Figure 6 ( ), which can be used for loading and unloading materials.

[0044] Afterwards, the first lifting mechanism 400 resets to the lowest preset initial position, waiting for the upper conveyor line 100 to convey the tray to the first position again.

[0045] In some embodiments of this application, the structures of the first positioning support portion 312 and the second positioning support portion are the same. Taking the structure of the first positioning support portion 312 as an example, the first positioning support portion 312 includes a first positioning support plate 3121 and a second positioning support plate 3122 arranged at an angle.

[0046] The first positioning support plate 3121 and the second positioning support plate 3122 are arranged at an angle, so that each positioning support plate can support the material tray over a large area, ensuring support reliability and reducing the number of positioning units and cost input.

[0047] In some embodiments of this application, see Figure 4 The first positioning support plate 3121 and the second positioning support plate 3122 are set at an L-shaped right angle according to the shape of the material tray.

[0048] In some embodiments of this application, when the material tray P1 is still held on the positioning mechanism 300, if the upper conveyor line 100 conveys the material tray P2 to the first position, the material tray P2 can be moved away by the handling mechanism 500 and placed on the top tray of the second lifting mechanism 700. Then, the second lifting mechanism 700 is used to lower the material tray P2 and transfer it to the lower conveyor line 800, so that the material tray P2 can be conveyed through the lower conveyor line 800, thereby improving the loading and unloading efficiency.

[0049] In some embodiments of this application, see Figures 5 to 7 The handling mechanism 500 includes a handling platform 510 and a handling support 520.

[0050] See Figure 1 The transport platform 510 can be set on the fixed platform 600 and can provide power for moving the material tray P2 off the upper conveyor line 100.

[0051] In some embodiments of this application, see Figure 7 The transport platform 510 includes a first drive assembly (unmarked), a first ball screw (unmarked), a first slide rail (unmarked), and a first connecting block (unmarked).

[0052] Both the first drive assembly and the first ball screw are fixed to the fixed platform 600. The screw extension direction of the first ball screw is along the conveying direction of the upper conveyor line 100. The first drive assembly is used to drive the first ball screw to rotate (for example, the first drive assembly may include a drive motor).

[0053] The first slide rail is fixed to the first ball screw, and the first connecting block is fixedly connected to the nut of the first ball screw and slidably disposed on the first slide rail. The first connecting block is also connected to the transport bracket 520. Therefore, when the first drive assembly is working, it drives the first ball screw to rotate, and the nut on it moves together with the first connecting block and the transport bracket 520, thus realizing the transport of the material tray P2.

[0054] In some embodiments of this application, a picking unit is provided on the transport bracket 520. When it is necessary to transport the material tray P2, the picking unit can pick up the material tray P2 on the upper conveyor line 100 and move it away.

[0055] In some embodiments of this application, the acquiring part can be a gripper, which is used to grab the material tray P2 when it is necessary to move the material tray P2.

[0056] To avoid damage or scratches to the material tray P2 during gripping, in some embodiments of this application, see [link to relevant documentation]. Figure 6 and Figure 7 The acquisition unit can be a vacuum suction cup assembly, which may include multiple vacuum suction cups 530 and a vacuum pump (not shown). Each vacuum suction cup 530 is connected to the vacuum pump. The multiple vacuum suction cups 530 are arranged on the side of the transport bracket 520 facing the upper conveyor line 100, and the adsorption surface of the vacuum suction cups 530 also faces the upper conveyor line 100. In this way, the vacuum suction cups 530 adsorb or release the material tray P2 through the operation of the vacuum pump.

[0057] In some embodiments of this application, in order to enable the adjustment of the distance between the transport bracket 520 and the upper conveyor line 100, a height adjustment mechanism (not shown) may also be provided for the transport bracket 520, which is also connected to the first connecting block.

[0058] In some embodiments of this application, in order to place the pallet P2 transported by the conveying mechanism 500 onto the top tray of the second lifting mechanism 700, see [reference needed]. Figure 1 A clearance part 610 is provided on the fixed platform 600, and the material tray P2 transported by the conveying mechanism 500 is placed on the top tray of the second lifting mechanism 700 through the clearance part 610.

[0059] When the material tray P2 has been placed on the top tray of the second lifting mechanism 700, and the second lifting mechanism 700 remains in its current state (i.e., has not yet descended), the position of the material tray P2 can also be used as a loading and unloading station. After the loading and unloading are completed, the second lifting mechanism 700 descends, which will drive the material tray P2 to be transported out on the lower conveyor line 800.

[0060] In some embodiments of this application, see Figure 1 The lifting direction of the second lifting mechanism 700 is perpendicular to the conveying direction of the upper conveyor line 100 and the lower conveyor line 200.

[0061] See Figure 8 The second lifting mechanism 700 includes a lifting platform 710 and a lifting support 720. The lifting platform 710 includes a frame (unmarked), a second ball screw (unmarked), a second drive assembly (unmarked), a second slide rail (unmarked), and a second connecting block (unmarked), wherein the lifting support 720 is fixedly connected to the second connecting block.

[0062] The frame can be fixed to the ground, for example. The second drive assembly and the second ball screw are both fixed to the frame. The extension direction of the second ball screw is along the lifting direction of the second lifting mechanism 700. The second drive assembly is used to drive the second ball screw to rotate (for example, the second drive assembly may include a drive motor).

[0063] The second slide rail is fixed to the second ball screw, and the sliding direction of the second slide rail is consistent with the extension direction of the second ball screw. The second connecting block is fixedly connected to the nut of the second ball screw and slidably disposed on the second slide rail. Since the second connecting block is also connected to the lifting support part 720, when the second drive assembly is working, it drives the second ball screw to rotate, and the nut on it, together with the second connecting block and the lifting support part 720, rises and falls together, thus realizing the lifting and lowering of the material tray P2.

[0064] When the second lifting mechanism 700 lowers until its top tray is below the conveying surface of the lower conveyor line 200, the tray P2 is supported by the lower conveyor line 200 and moved along the lower conveyor line 200. Figure 5 The direction indicated by the dashed arrow at the midpoint is for delivery away.

[0065] In some embodiments of this application, in order to achieve stable support of the material tray P2 by the lifting support part 720, the lifting support part 720 includes a first support plate 721 and a second support plate 722. The first support plate 721 is connected to the second connecting block. The first support plate 721 and the second support plate 722 are connected in an L-shape. The second support plate 722 forms the top tray of the second lifting mechanism 700 as described above, for supporting the material tray P2.

[0066] To enhance the strength of the lifting support 720, a reinforcing plate 723 is provided at the corner between the first support plate 721 and the second support plate 722.

[0067] The loading and unloading device described above can effectively utilize space through the upper conveyor line 100 and the lower conveyor line 200, reducing the overall area occupied by the device.

[0068] The tray unloading mechanism 200 cyclically places a single tray onto the upper conveyor line 100, improving automation and efficiency. The trays on the upper conveyor line 100 are lifted to the positioning mechanism 300 by the first lifting mechanism 400, forming a loading / unloading station for loading and unloading. The trays conveyed again by the upper conveyor line 100 are transported by the handling mechanism 500 to the second lifting mechanism 700, which can serve as another loading / unloading station. At the same time, the trays on the second lifting mechanism 700 can be transported to the lower conveyor line 800 and transported out. Multiple loading / unloading stations meet the loading / unloading needs of the device, and the upper and lower conveyor lines transport trays separately, improving loading / unloading efficiency.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
