[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Refer to Figures 1 to 6 , an empty tray collection device 2000 in some embodiments of the present utility model is used for the recycling and collection of the empty tray 1.

[0033] The empty tray collection device 2000 includes a support frame 2100. The support frame 2100 encloses an empty tray accommodation space, and the support frame 2100 includes a support frame body 2110.

[0034] The empty tray collection device 2000 includes a lifting drive assembly 2200. The lifting drive assembly 2200 is located below the empty tray accommodation space, and an empty tray support plate 2400 is provided on its lifting output end. The lifting drive assembly 2200 is used to lift the empty tray 1 on the empty tray support plate 2400 into the empty tray accommodation space through the empty tray support plate 2400.

[0035] The empty tray collection device 2000 includes a plurality of chuck assemblies 2300, and an empty tray support plate 2400 is provided on the lifting output end of the lifting drive assembly 2200; the plurality of chuck assemblies 2300 are arranged on the support frame body 2110 along the extension direction of the support frame body 2110 for supporting the empty trays collected in the empty tray accommodation space.

[0036] Then, the empty tray collection device 2000 in the embodiment of the present invention can stack the empty trays 1 in sequence from bottom to top, realizing the automatic, orderly and stacked collection of the empty trays 1, greatly improving the collection efficiency of the empty trays 1, and facilitating the subsequent centralized handling or processing of the empty trays 1 after collection.

[0037] In some embodiments of the present invention, the empty tray collection device 2000 is configured with a conveyor line 1000. The conveyor line 1000 is used to convey (the conveying direction is as shown by the arrow I in Figure 1 the figure) the empty trays 1 to be collected to the position where the empty tray collection device 2000 is located. The conveyor line 1000 is located below the empty tray accommodation space.

[0038] In some embodiments of the present invention, the conveyor line 1000 can be a double-belt conveyor line. The two belt conveyor lines operate synchronously. The two belt conveyor lines are arranged oppositely and spaced apart by a certain distance, providing an installation space for the empty tray collection device 2000 and providing an avoidance space for the related actions of each moving part, such as the lifting of the lifting output end of the lifting drive assembly 2200 driving the lifting of the empty tray support plate 2400. The support frame 2100 can be arranged on the conveyor line frame body, and the lifting drive assembly 2200 can be arranged between the two belt conveyor lines.

[0039] The width of the empty tray support plate 2400 is less than the distance between the two belts of the conveyor line 1000, and the width of the empty tray 1 is also less than the distance between the two belts of the conveyor line 1000, so that the conveyor line 1000 can avoid the lifting of the empty tray support plate 2400 and the lifting of the empty tray 1 into the empty tray accommodation space by the empty tray support plate 2400.

[0040] In the initial state, the lifting output end of the lifting drive assembly 2200 drives the empty tray support plate 2400 to be located below the conveyor line 1000, as shown in Figure 4As shown, when the empty material tray 1 is transported by the conveyor line 1000 to the empty material tray support plate 2400, the lifting output end of the lifting drive assembly 2200 extends upward, lifting the empty material tray 1 to move it upward and away from the conveyor line 1000. When the empty material tray 1 reaches the empty material tray accommodating space and reaches above the chuck assembly 2300, the lifting output end of the lifting drive assembly 2200 retracts downward to return to its original position, and the empty material tray 1 falls on the chuck assembly 2300 and is supported on the chuck assembly 2300. When the next empty material tray 1 reaches the empty material tray support plate 2400, the lifting output end of the lifting drive assembly 2200 extends upward. , the empty material tray 1 is lifted to move upward and away from the conveyor line 1000. When the empty material tray 1 contacts the empty material tray 1 that has been collected before it, the lifting output end of the lifting drive assembly 2200 continues to extend upward, and the empty material tray 1 is lifted together with the collected empty material tray 1 to above the chuck assembly 2300. The lifting output end of the lifting drive assembly 2200 retracts downward and returns to its original position. The empty material tray 1 and the collected empty material tray 1 fall on the chuck assembly 2300 together and are supported on the chuck assembly 2300. The remaining empty material trays 1 are collected in this way in turn, thereby realizing the stacking and collection of the empty material trays 1 from bottom to top.

[0041] From the above-mentioned empty tray 1 collecting action, it can be known that the chuck assembly 2300 needs to be able to avoid the empty tray 1 when the empty tray 1 moves upward, and to support the empty tray 1 when the empty tray 1 descends above the chuck assembly 2300 and is supported on the chuck assembly 2300. Therefore, the empty tray 1 needs to be able to move to a position that avoids the upward movement of the empty tray 1, and to move to a supporting position.

[0042] In some embodiments of the present invention, the chuck assembly 2300 includes a rotating component 2310, which is rotatably disposed on the supporting frame body 2110 and can be rotated to an avoidance position and a supporting position.

[0043] When in the avoidance position, the rotating component 2310 avoids the empty tray 1 and moves it up to the empty tray accommodating space, that is, in the process of the lifting drive assembly 2200 lifting the empty tray 1 to the empty tray accommodating space through the empty tray support plate 2400, there is no interference with the empty tray 1; when in the supporting position, the empty tray 1 in the empty tray accommodating space is supported on the rotating component 2310; that is, when the empty tray 1 moves up, the rotating component 2310 rotates to the avoidance position to avoid the empty tray 1 from moving up to above the chuck assembly 2300, and then the rotating component 2310 rotates to the supporting position to support the empty tray 1 and limit the empty tray 1 from continuing to move downward, and only the lifting output end of the lifting drive assembly 2200 moves downward and retracts to return to its original position.

[0044] As a specific implementation method, Figures 2 to 6As shown, the rotating component 2310 is a triangular block structure, the inner edge of its top surface is its planar support surface 2311, and the rotating component shaft 2312 is located at the bottom tip of the triangular block.

[0045] The axis of the rotating member shaft 2312 is a horizontal axis and is parallel to the conveying direction of the conveyor line 1000. The rotating member shaft 2312 is eccentrically connected to the rotating member 2310, and under the deadweight of the rotating member 2310, the rotating member 2310 can automatically rotate to the supporting position, and under the action of external force, the rotating member 2310 rotates to the avoidance position.

[0046] like Figures 2 to 6 In the perspective shown, the rotating member 2310 rotates counterclockwise to the supporting position and rotates clockwise to the avoiding position. In the supporting position, the planar supporting surface 2311 of the rotating member 2310 is in a horizontal state and is located on the upward and downward movement path of the empty material tray 1 so as to fit against the outer flange 1-1 of the bottom edge of the empty material tray 1.

[0047] The rotation driving force of the rotating component 2310 to the avoidance position comes from the thrust of the upward moving empty material tray 1, that is, when the lifting output end of the lifting drive assembly 2200 lifts the empty material tray 1 upward through the empty material tray support plate 2400, the empty material tray 1 moves up to contact the bottom of the rotating component 2310 located at the supporting position, and continues to be lifted. The empty material tray 1 continues to move up, which pushes the rotating component 2310 to rotate clockwise. The upward moving direction of the empty material tray 1 and the rotation direction of the rotating component 2310 are as shown in FIG. Figure 4 As shown by the dotted arrow, when the empty material tray 1 pushes the rotating part 2310 to rotate clockwise until the empty material tray 1 is about to be separated from the rotating part 2310, the position of the rotating part 2310 at this time is the avoidance position (at this time, the planar support surface 2311 of the rotating part 2310 is roughly parallel to the vertical direction), the empty material tray 1 continues to move up and separates from the rotating part 2310, and the empty material tray 1 reaches above the rotating part 2310. The rotating part 2310 rotates and resets to the supporting position under its own weight, and then the lifting output end of the lifting drive assembly 2200 retracts downward, driving the empty material tray 1 to move down to the planar support surface 2311 supported on the rotating part 2310, thereby realizing the collection of the empty material tray 1.

[0048] The rotating component 2310 with the above structure does not need to be provided with an additional rotating driving structure to drive the rotating component 2310, so that the chuck assembly 2300 has a simple structure, fewer movements, and more stable operation.

[0049] In some embodiments of the utility model, the chuck assembly 2300 also includes a limiting component 2320, which is used to abut against the rotating component 2310 when the empty material tray 1 is supported on the rotating component 2310, thereby limiting the rotation of the rotating component 2310 and allowing the rotating component 2310 to stably maintain the supporting position, further improving the support reliability.

[0050] As Figure 3 , Figure 5 and Figure 6 shown, the limiting member 2320 is a limiting stop rod fixedly provided on the support frame body 2110. It is located above the rotating member 2310 and close to the outer edge of the top surface, and the plane support surface 2311 of the rotating member 2310 and the limiting member 2320 are respectively located on both sides of the rotating shaft 2312 of the rotating member. When the empty tray 1 is supported on the rotating member 2310, the gravity of the empty tray 1 will cause the rotating member 2310 to have a tendency to rotate counterclockwise. At this time, the limiting member 2320 abuts against and stops the rotating member 2310 to limit its rotation, so that the empty tray 1 can be stably supported on the rotating member 2310.

[0051] In some embodiments of the present utility model, the chuck assembly 2300 further includes a fixed seat 2330. The fixed seat 2330 is fixedly provided on the support frame body 2110. The rotating shaft 2312 of the rotating member is installed on the fixed seat 2330, and the limiting member 2320 is also installed on the fixed seat 2330. Then during installation, the rotating member 2310, the limiting member 2320 and the fixed seat 2330 can be pre-assembled into one body first, and then installed on the support frame body 2110, which improves the installation convenience.

[0052] When the lifting drive assembly 2200 drives the empty tray 1 to move upward through the empty tray support plate 2400, the empty tray 1 pushes the rotating member 2310 to rotate to avoid the empty tray 1 moving upward above the rotating member 2310. When the lifting drive assembly 2200 drives the empty tray support plate 2400 to move downward and separate from the empty tray 1, the empty tray 1 is supported on the rotating member 2310.

[0053] Similarly, since the outer contour of the tray is usually rectangular, the support frame body 2110 is in the shape of a rectangular frame. As Figure 2 shown, a plurality of chuck assemblies 2300 are respectively arranged at the four corner parts of the support frame body 2110, specifically arranged on two relatively arranged support beams of the support frame body 2110, and the length directions of these two support beams are parallel to the conveying direction of the conveying line 1000.

[0054] Taking the number of chuck assemblies 2300 as four sets as an example, in the above two relatively arranged support beams, one set of chuck assemblies 2300 is arranged at each end of each support beam, and the chuck assemblies 2300 on the two support beams are arranged oppositely.

[0055] The empty tray 1 and the support frame body 2110 are coaxial. The inner contour size of the support frame body 2110 is larger than the outer contour size of the empty tray 1 and also larger than the outer contour size of the empty tray support plate 2400, so that the empty tray support plate 2400 can drive the empty tray 1 to move upward or downward through the inner space of the support frame body 2110.

[0056] In some embodiments of the present utility model, the support frame 2100 further includes a plurality of limiting columns 2120 disposed on the support frame body 2110 along the extending direction of the support frame body 2110. The limiting columns 2120 extend vertically, and together with the support frame body 2110, they enclose a space for accommodating empty trays. The plurality of limiting columns 2120 can surround the stacked empty trays 1, restricting the outward sliding of the empty trays 1 and improving the safety of use of the entire empty tray collection device 2000.

[0057] Furthermore, the cross-section of the limiting column 2120 is rectangular, and a guiding inclined surface is formed at the top of its inner side surface (i.e., the side surface facing the space for accommodating empty trays among the circumferential side surfaces of the limiting column 2120), so as to play a guiding role when placing the stacked empty trays 1 and facilitate the placement of the stacked empty trays 1.

[0058] When the support frame body 2110 is in the shape of a rectangular frame, the limiting columns 2120 are disposed on its four support beams, and the limiting columns 2120 on two opposite support beams are symmetrically arranged. Moreover, the height positions of the tops of the limiting columns 2120 on these two support beams are lower than the height positions of the tops of the limiting columns 2120 on the other two opposite support beams, as Figure 2 and Figure 4 shown, so that when the quantity of stacked empty trays 1 is large, the empty trays 1 can be taken away part by part from the upper side, facilitating the tray taking.

[0059] The lifting drive assembly 2200 can be selected as a cylinder or an oil cylinder, etc. The cylinder or the oil cylinder is erected and fixedly arranged on a foundation (such as the ground) through a fixed support.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements 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 the present utility model.
