Description

Technical Field

[0001] This utility model relates to a transfer device, and more particularly to an automatic tray loading and unloading machine. Background Technology

[0002] In the powder processing industry, material trays are commonly used. Powder is filled into the material trays, which are then transferred to other processes for further processing. To facilitate the centralized transfer of material trays, transfer boxes are usually used in the powder processing industry. These transfer boxes can hold material trays in layers.

[0003] Existing transfer boxes have a relatively simple structure and function, and cannot automatically guide or unload trays. Therefore, during production, manual placement and removal of trays are still required, resulting in low automation, reduced production efficiency, and increased labor costs. Furthermore, these types of transfer boxes cannot be directly integrated into production lines, causing problems for manufacturers. Utility Model Content

[0005] An automatic tray loading and unloading machine includes a positioning mechanism and a transfer box. The transfer box is used to hold trays. The positioning mechanism is used to limit and fix the transfer box and adjust its height. The transfer box includes a frame, a roller assembly and a lifting module mounted on the frame, a linear module mounted on the lifting module, and a tray gripping mechanism mounted on the linear module. The linear module and the lifting module respectively drive the tray gripping mechanism to adjust its position in the horizontal and vertical directions. The frame has an open inner space, and the roller assembly is arranged in the inner space, with the roller assemblies distributed sequentially along the vertical direction.

[0006] In one embodiment, the material gripping disc mechanism includes a drive device, a linkage rod connected to the drive device, and a hook mounted on the linkage rod. The hook has hooks on both sides, and the drive device drives the hook to adjust its angle through the linkage rod.

[0007] In one embodiment, the roller strip assembly includes two roller strips disposed opposite each other, each roller strip including a support portion and a roller rotatably mounted inside the support portion.

[0008] In one embodiment, a guide groove is provided on the inner side of the upper end face of the support, and the height of the top of the roller is higher than the bottom surface of the guide groove.

[0009] In one embodiment, the guide groove wall at the front side of the support is provided with an outwardly inclined guide surface, which guides the material tray when it is pushed into the guide groove.

[0010] In one embodiment, the positioning mechanism includes a positioning frame, a plurality of adjustment modules mounted on the positioning frame, a base mounted on the adjustment modules, and a plurality of positioning components mounted on the base. The adjustment modules drive the base and the positioning components mounted on the base to adjust in the vertical direction.

[0011] In one embodiment, the positioning components of the positioning mechanism are mounted on the base in two rows.

[0012] In one embodiment, the positioning component includes a positioning seat and a support plate mounted on the positioning seat. The upper end of the positioning seat has a downwardly inclined guide surface near the inner side, and the positioning seat further has a mounting groove at the bottom of the guide surface. The support plate is mounted at the bottom of the mounting groove.

[0013] In one embodiment, the positioning component further includes an auxiliary frame mounted on the bottom of the support plate and a micro switch mounted on the auxiliary frame.

[0014] In one embodiment, the support plate has a through hole extending downwards, and the micro switch has a contact. When the contact of the micro switch is released, the contact of the micro switch passes through the through hole and extends into the upper part of the support plate.

[0029] Please see Figures 1 to 8 This utility model provides an automatic tray loading and unloading machine for automatically loading and unloading trays 300. The machine includes a positioning mechanism 200 and a transfer box 100. The transfer box 100 is used to hold the trays 300, and the positioning mechanism 200 is used to limit and fix the transfer box 100 and adjust its height during operation. In this embodiment, the tray 300 is generally square, and a material trough 310 extending downwards from the top is provided on the tray 300.

[0030] The transfer box 100 includes a frame 10, a roller strip group 20 and a lifting module 30 mounted on the frame 10, a linear module 40 mounted on the lifting module 30, and a material gripping plate mechanism 50 mounted on the linear module 40. The linear module 40 and the lifting module 30 respectively drive the material gripping plate mechanism 50 to adjust its position in the horizontal and vertical directions.

[0031] The frame 10 has an open inner space 11, and the roller strip group 20 is arranged in the inner space 11. Each roller strip group 20 includes two roller strips 21 arranged opposite each other. The roller strip groups 20 are distributed in sequence along the vertical direction. Each roller strip 21 includes a support part 22 and a roller 23 that is rolled and installed inside the support part 22. The upper end surface of the support part 22 is provided with a guide groove 221 near the inner side. The top of the roller 23 is higher than the bottom surface of the guide groove 221. Furthermore, the guide groove 221 near the front side has an outwardly inclined guide surface 222. The inclined guide surface 222 guides the material tray 300 when it is pushed into the guide groove 221.

[0032] In this embodiment, both the lifting module 30 and the linear module 40 are driven by a lead screw. There are two sets of lifting modules 30, which are installed on the same side of the frame 10 at the front and rear positions. The linear module 40 is installed on both sets of lifting modules 30.

[0033] Specifically, the lifting module 30 includes a frame body 31, an inner guide rail (not shown) mounted on the frame body 31, a drive motor 32 mounted on the frame body 31 and located on one side of the inner guide rail, a slider 33 slidably mounted on the inner guide rail, a first lead screw (not shown) connected to the drive motor 32 and passing through the slider 33, and a connecting block 34 mounted on the slider 33. The inner guide rail is installed vertically, and the lead screw passes through the slider 33 vertically. The lead screw and the slider 33 are installed with a threaded connection. The linear module 40 is mounted on the connecting block 34. When the drive motor drives the lead screw to rotate, the lead screw drives the slider 33, which is threadedly connected to it, to slide and adjust along the inner guide rail. During the movement of the slider 33, the connecting block 34 and the linear module 40 are adjusted synchronously.

[0034] The linear module 40 is similar in structure to the lifting module 30. The main difference is that the inner guide rail on the linear module 40 is installed in the horizontal direction, the lead screw on the linear module 40 passes through the slider of the linear module in the horizontal direction, and the material gripping plate mechanism 50 is installed on the connecting block of the linear module 40. Since the lead screw drive method is a mechanical structure well known to those skilled in the art, it will not be described in detail here.

[0035] The material gripping disc mechanism 50 includes a drive device 51, a linkage rod 52 connected to the drive device 51, and a hook 53 mounted on the linkage rod 52. The hook 53 is generally T-shaped, and hook portions 531 are formed on both sides of the hook 53. The drive device 51 drives the hook 53 to adjust its angle along the axis of the linkage rod 52 through the linkage rod 52. In this embodiment, the drive device 51 is a motor.

[0036] The positioning mechanism 200 includes a positioning frame 60, a plurality of adjustment modules 70 mounted on the positioning frame 60, a base 80 mounted on the adjustment modules 70, and a plurality of positioning components 90 mounted on the base 80. Each positioning component 90 includes a positioning seat 91, a support plate 92 mounted on the positioning seat 91, an auxiliary frame 93 mounted on the bottom of the support plate 92, and a micro switch 94 mounted on the auxiliary frame 93. The structure of the adjustment module 70 is similar to that of the lifting module 30. The adjustment module 70 is also driven by a lead screw. The adjustment module 70 is used to drive the base 80 and the positioning components 90 mounted on the base 80 to adjust in the vertical direction.

[0037] The positioning components 90 of the positioning mechanism 200 are arranged in two rows and installed on the base 80. The upper end of the positioning seat 91 has a downwardly inclined guide surface 911 on the inner side. The positioning seat 91 further has a mounting groove 912 at the bottom of the guide surface 911. The support plate 92 is installed at the bottom of the mounting groove 912. The support plate 92 has a downward through hole 921. When the contact of the micro switch 94 is released, the contact of the micro switch 94 passes through the through hole 921 and extends into the upper part of the support plate 92. Conversely, when the contact of the micro switch 94 is pressed down, the contact of the micro switch 94 retracts into the through hole 921.

[0038] During use, the automatic tray loading and unloading machine is connected to the production line. The opening of the inner space 11 on the frame 10 faces the production line. When it is necessary to transfer the tray 300 that has been filled on the production line to the transfer box 100, the AGV trolley places the transfer box 100 on the positioning mechanism 200. The two sides of the transfer box 100 pass over the guide surfaces 911 of the two rows of positioning seats 91 and press down on the auxiliary frame 93. The bottom surface of the transfer box 100 presses down on the contacts of the micro switch 94. The staff determines whether the transfer box 100 has been positioned based on the signal of the micro switch 94.

[0039] The positioning module 70 of the positioning mechanism 200 drives the transfer box 100 to adjust upwards, so that the bottom roller assembly 20 on the transfer box 100 is aligned with the production line. The linear module 40 drives the gripping disc mechanism 50 to adjust horizontally, so that the gripping disc mechanism 50 moves to the position near the opening of the inner space 11. The lifting module 30 drives the gripping disc mechanism 50 to move vertically, so that the gripping disc mechanism 50 moves to the position near the frontmost material tray 300 on the production line. The drive device 51 of the gripping disc mechanism 50 drives the hook 53 to rotate, and the hook part 531 of the hook 53 can extend into the material groove 310 of the material tray 300. The linear module 40 drives the hook 53 to move backwards. 53. Pull the tray 300 above the bottom roller assembly 20. The roller assembly 20 supports the tray 300. During the next transfer, the positioning module 70 of the positioning mechanism 200 moves the transfer box 100 downward, so that the second roller assembly 20 on the transfer box 100, which is adjacent to the bottom roller assembly 20, is aligned with the production line. The lifting module 30 moves the tray gripping mechanism 50 upward by one position. The tray gripping mechanism 50, together with the linear module 40, moves the tray 300 on the production line to the second roller assembly 20. Repeat the above steps until the entire transfer box 100 is filled with tray 300. Then the AGV trolley moves the transfer box 100 to the designated position.

[0040] When the tray 300 in the transfer box 100 needs to be moved out, the adjustment module 70 of the positioning mechanism 200 drives the transfer box 100 to adjust upward layer by layer, so that the roller strips 20 on different layers move to the same position as the production line. Each time the adjustment is completed, the lifting module 30 drives the gripping tray mechanism 50 to adjust downward one position accordingly. The gripping tray mechanism 50, together with the linear module 40, transfers the tray 300 on the roller strip 20 to the production line. When the tray 300 is pushed outward, the hook 53 hooks onto the rear side of the tray 300.

[0041] The beneficial effects of this automatic tray loading and unloading machine are as follows: By setting a positioning mechanism 200 and a transfer box 100, the positioning mechanism 200 can adjust the height of the transfer box 100. A frame 10, roller assembly 20, lifting module 30, linear module 40, and tray gripping mechanism 50 are arranged on the transfer box 100. The roller assembly 20 is arranged vertically. The linear module 40 and lifting module 30 respectively drive the tray gripping mechanism 50 to adjust its position in the horizontal and vertical directions to transfer the tray 300. The entire transfer process requires no manual intervention, has a high level of automation, and effectively saves labor costs.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
