Description

Technical Field

[0001] This application relates to the field of loading and unloading equipment technology, and in particular to a material tray elevator. Background Technology

[0002] Material handling equipment is a device used in industrial automation for automatic loading and unloading of materials. It uses robotic arms, feeders, gantry systems or AGVs to accurately grab, transport and place raw materials or semi-finished products, replacing manual labor in loading and unloading operations of machine tools, stamping machines, injection molding machines and other equipment.

[0003] In automated production lines, some materials need to be placed in trays to facilitate material loading or to place processed materials in the trays.

[0004] In related technologies, when it is necessary to replenish the material trays in the hopper of the material tray unloader or to remove the material trays from the hopper, the material tray unloader needs to be stopped, and the hopper drawer needs to be pulled out to replenish the material trays or to remove the full material trays from the drawer.

[0005] Regarding the aforementioned technologies, the inventors believe that during the loading and unloading process, stopping the machine not only leads to low production efficiency, but also requires operators to be able to replenish or remove the material trays in a timely and rapid manner, which places high demands on the operators. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a material tray lifting machine, which solves the technical problem that during the loading and unloading process, stopping the machine will not only cause low production efficiency, but also require the operator to be able to replenish or remove the material tray in a timely and fast manner, which places high demands on the operator.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A material tray lifting device includes: a frame for supporting the lifting device, the frame having a loading area and a unloading area; a trolley located on one side of the frame, the trolley moving towards or away from the frame, the trolley for loading or unloading materials onto or off the frame; a loading assembly mounted on the frame for loading a material tray containing material; a transport assembly mounted on the frame for transporting the material tray from the loading area to the unloading area; and an unloading assembly mounted on the frame for unloading an empty material tray.

[0009] Furthermore, the feeding assembly includes a feeding plate, which is slidably mounted on the frame. The frame is equipped with a feeding motor and a feeding screw. The feeding screw is rotatably mounted on the frame and is threadedly connected to the feeding plate. The feeding motor drives the feeding screw to rotate.

[0010] Furthermore, the feeding assembly includes a feeding plate, which is slidably mounted on the frame. The frame is equipped with a feeding motor and a feeding screw. The feeding screw is rotatably mounted on the frame and is threadedly connected to the feeding plate. The feeding motor drives the feeding screw to rotate.

[0011] Furthermore, the conveying assembly includes a sliding frame that is slidably mounted on the frame. The sliding frame is equipped with grippers and a clamping cylinder, and the clamping cylinder drives the grippers to clamp the material tray.

[0012] Furthermore, a clamping plate and a drive cylinder are provided on the side of the frame near the feeding area. The drive cylinder is mounted on the frame, and the clamping plate is mounted on the piston rod of the drive cylinder.

[0013] Furthermore, a rotary motor is provided on the frame, the rotary motor is mounted on the frame, and a positioning plate is provided on the output shaft of the rotary motor.

[0014] Furthermore, positioning blocks are provided on the loading plate and the unloading plate, and a number of positioning blocks are spaced apart. A positioning groove is formed between the number of positioning blocks, and a guide slope is formed on the positioning block. The guide slope is inclined toward the side close to the positioning groove.

[0015] In summary, this application includes at least one of the following beneficial technical effects of the material tray lifting mechanism:

[0016] In operation, a trolley transports a tray filled with material to the loading area of ​​the machine frame. The loading component loads the tray. Once the material in the tray is removed, the transport component moves the tray from the loading area to the unloading area. Then, the unloading component unloads the tray. After the empty tray is unloaded, the trolley removes the tray from the unloading area. Operators can place multiple trays in the loading area at once. As the trays are continuously used, the empty trays are transported to the unloading area by the transport component. This allows one loading operation to meet the processing needs of one operation, reducing the need for equipment downtime and improving production efficiency. It also eliminates the need for operators to replenish or remove trays quickly and promptly, reducing the requirements for operators.

[0017] The feeding motor and feeding screw drive the feeding plate to move on the frame, and the unloading motor and unloading screw drive the unloading plate to move on the frame, which improves the convenience of feeding and unloading the material tray.

[0018] By rotating the motor and setting up the positioning plate and positioning block, the accuracy of the material tray's position on the frame is improved. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a material tray lifting machine.

[0027] Reference Figure 1 A material tray lifting device includes a frame 1, on which a loading area 11 and a unloading area 12 are formed. A trolley 2 is provided on one side of the frame 1 for conveying material trays. The frame 1 is provided with a loading assembly 3, an unloading assembly 4, and a conveying assembly 5. The loading assembly 3 is used to load material trays filled with material. The conveying assembly 5 transports empty material trays from the loading area 11 to the unloading area 12. The unloading assembly 4 is used to unload empty material trays. The trolley 2 transports empty material trays in the unloading area 12.

[0028] The feeding assembly 3 is located on the side of the frame 1 near the feeding area 11, and the unloading assembly 4 is located on the side of the frame 1 near the unloading area 12. The conveying assembly 5 slides between the feeding area 11 and the unloading area 12 to convey the material tray.

[0029] Reference Figure 2 The feeding assembly 3 includes a feeding plate 31, which is rectangular in shape and has one open side along its length. The trolley 2 is pushed into the feeding plate 31 from the open side. In order for the material tray filled with material to be lifted on the frame 1, and because the material tray filled with material is relatively heavy, two sets of feeding assemblies 3 are arranged at intervals on the frame 1. The two sets of feeding assemblies 3 are located on both sides of the material tray. In use, the two sets of feeding assemblies 3 lift the material tray.

[0030] Furthermore, the feeding assembly 3 includes a feeding motor 32 and a feeding screw 33. The feeding screw 33 is rotatably mounted on the frame 1, with one end passing through the feeding plate 31 and threadedly connected to it. In use, the feeding motor 32 drives the feeding screw 33 to rotate. As the feeding motor 32 drives the feeding screw 33 to rotate forward or backward, the feeding plate 31 is raised or lowered on the frame 1.

[0031] When unloading an empty tray using the unloading assembly 4, since the empty tray is relatively light, the unloading assembly 4 is only located on one side of the tray. Furthermore, the unloading assembly 4 includes an unloading plate 41, which is rectangular in shape, with one side of its length open. The trolley 2 is pushed into the unloading plate 41 from the open side. When an empty tray is placed on the unloading plate 41, the trolley 2 is pushed into the unloading plate 41 to remove the empty tray.

[0032] To improve the ease of raising and lowering the feeding tray on the frame 1, the feeding assembly 4 includes a feeding motor 42 and a feeding screw 43. The feeding screw 43 is rotatably mounted on the frame 1, with one end passing through the feeding plate 41 and threadedly connected to it. In use, the feeding motor 42 drives the feeding screw 43 to rotate. As the feeding motor 42 drives the feeding screw 43 to rotate forward or backward, the feeding plate 41 is raised and lowered on the frame 1.

[0033] Furthermore, a clamping plate 13 and a drive cylinder 14 are provided on the side of the frame 1 near the feeding area 11. Two sets of clamping plates 13 and drive cylinders 14 are arranged opposite each other on the frame 1, with the two sets of drive cylinders 14 and clamping plates 13 located on both sides of the length of the feeding plate 31. After several trays are placed on the feeding plate 31, the feeding plate 31 rises under the drive of the feeding motor 32 and the feeding screw 33. As materials are taken from the trays, empty trays are continuously conveyed to the feeding area 12. When only one tray remains on the feeding plate 31, the drive cylinder 14 drives the clamping plate 13 to clamp the tray. At the same time, the feeding motor 32 and the feeding screw 33 drive the feeding plate 31 to descend, and the operator replenishes materials to the feeding area 11. This eliminates the need to stop the machine during processing, greatly improving the material processing efficiency.

[0034] Reference Figure 3 During the movement of the trolley 2 towards the frame 1, in order to ensure that the trolley 2 can be pushed into place on the frame 1, a rotary motor 15 is installed on the frame 1. The rotary motor 15 is mounted on the frame 1, and one end of the output shaft of the rotary motor 15 faces the side closer to the trolley 2. A positioning plate 151 is installed on the output shaft of the rotary motor 15. The positioning plate 151 is rectangular in shape. In the initial state, the positioning plate 151 is vertically set. When the trolley 2 is pushed into the frame 1, the rotary motor 15 drives the positioning plate 151 to rotate. The positioning plate 151 pulls the trolley 2 tightly on the frame 1, thereby preventing the position of the trolley 2 from deviating from the frame 1 during use.

[0035] Furthermore, to ensure the stability of the material tray's position on the upper plate 31 and the lower plate 41, positioning blocks 34 are provided on both the upper plate 31 and the lower plate 41. Four positioning blocks 34 are spaced apart at the four corners of the upper plate 31 and the lower plate 41. Positioning grooves 341 are formed in the four positioning blocks 34. Furthermore, guide slopes 342 are formed on the inner side of the four positioning blocks 34, with the guide slopes 342 facing the side closest to the positioning grooves 341. In use, the material tray is placed inside the positioning grooves 341 of the four positioning blocks 34, thereby preventing the material tray from shifting its position on the upper plate 31 and the lower plate 41.

[0036] Reference Figure 4 The conveying assembly 5 includes a sliding frame 51, which slides between the loading area 11 and the unloading area 12. Furthermore, the sliding frame 51 is equipped with grippers 52 and a clamping cylinder 53. The clamping cylinder 53 is mounted on the sliding frame 51, and the grippers 52 are mounted on the clamping cylinder 53. In use, the clamping cylinder 53 controls the grippers 52 to move towards or away from each other. When the material in the loading area 11 is used up, the sliding frame 51 slides above the loading area 11, and then the clamping cylinder 53 drives the grippers 52 to clamp the empty tray. The tray then moves above the unloading area 12 under the influence of the sliding frame 51.

[0037] Furthermore, in order to enable the sliding frame 51 to slide on the frame 1, a sliding cylinder 54 is provided on the frame 1, the sliding cylinder 54 is mounted on the frame 1, and the sliding frame 51 is mounted on the sliding cylinder 54. In use, the sliding frame 51 slides on the frame 1 via the sliding cylinder 54.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
