Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and more specifically, to an automatic circulating material rack for production line turnover boxes. Background Technology

[0002] In the material handling process in the production workshop, manual handling is currently the most common method for handling turnover boxes. Workers must lift the turnover boxes containing parts from the material carts and transfer them to various racks. After the assembly personnel have used the materials, the empty turnover boxes must be manually moved back from the racks to the material carts or the next workstation. This traditional handling method has many problems. The mechanization level of manual handling is extremely low, the entire process is time-consuming and labor-intensive, severely impacting production efficiency. Workers need to frequently repeat handling actions, resulting in extremely high labor intensity, and the speed of manual handling is limited, making it difficult to meet the operational needs of batch and large-scale production. Utility Model Content

[0003] To address the aforementioned problems, the present invention provides an automatic circulating material rack for production line turnover boxes, which solves the problems of low efficiency and high labor intensity of existing turnover box transfer methods. The rack includes a material rack with a frame structure; the rack comprises an adjacent circulating section and a picking section. The circulating section has an upper slide and a lower slide arranged vertically, with the discharge ends of both the upper and lower slides inclined downwards. The picking section has a traction mechanism, the output end of which is connected to a floating material platform that cooperates with the upper and lower slides. The traction mechanism drives the floating material platform to reciprocate between the upper and lower slides. Below the floating material platform is a limiting mechanism adjacent to the lower slide, which is rotatably connected to the picking section.

[0004] Preferably, the traction mechanism includes a traction drive unit located at the top of the material handling section, at least one guide wheel, and a traction rope. The output shaft of the traction drive unit is equipped with a drive wheel, one end of the traction rope is connected to the drive wheel, and the other end is connected to the floating material platform via the guide wheel.

[0005] Preferably, the limiting mechanism includes a base plate and a limiting rod fixed on the material receiving part, as well as a receiving plate that supports the floating material platform. The receiving plate is rotatably connected to the base plate, and the limiting rod cooperates with the receiving plate to limit its movement.

[0006] Preferably, two support shaft seats are symmetrically provided on the base plate, and a support shaft is provided between the two support seats. A connecting block is rotatably connected to the support shaft, and the connecting block is connected to the bottom surface of the receiving plate.

[0007] Preferably, the height of the limiting rod is greater than the height of the connecting block.

[0008] Preferably, at least one buffer block is symmetrically provided on both sides of the base plate.

[0009] Preferably, the upper slide, the lower slide, and the floating material platform are symmetrically provided with slide rails, and the slide rails are provided with a number of rollers that cooperate with the turnover box.

[0010] Preferably, the traction mechanism further includes an operating platform and a control system disposed on the material handling section. The surface of the operating platform is provided with an emergency stop switch and a push-button switch. The emergency stop switch and the push-button switch are electrically connected to the control system, and the control system is electrically connected to the traction drive unit.

[0011] Preferably, casters are provided at the four corners of the bottom of the material rack.

[0012] The beneficial effects of this utility model are as follows: Through the cooperation of the upper slide, lower slide, traction mechanism, floating material platform, and limiting mechanism, the automatic circulation and transfer of turnover boxes on the material rack is realized, eliminating the need for manual handling, saving labor costs, and improving material transfer efficiency. Workers only need to retrieve materials from the floating material platform, without having to lift and lower the turnover boxes, reducing labor intensity and improving the safety of manual operations. The limiting rod, in conjunction with the receiving plate, provides a hard limit on the turnover box. The limiting rod, by blocking the receiving plate, causes the turnover box to tilt in the opposite direction under the impact force and the reaction force of the limiting rod, forming an inclination angle towards the lower slide. This ensures that the turnover box can accurately slide into the lower slide, improving the accuracy and stability of turnover box transfer. Attached Figure Description

[0022] The present application will now describe an automatic circulating material rack for production line turnover boxes provided in the embodiments of this application.

[0023] Please see Figures 1 to 4The automatic circulating material rack for the production line includes a material rack 1, which is a frame structure. The material rack 1 includes a circulating section 101 and a picking section 102 arranged adjacent to each other. The circulating section 101 is provided with an upper slide 2 and a lower slide 3 arranged vertically. The discharge ports of the upper slide 2 and the lower slide 3 are both inclined downwards. The upper slide 2 is used to receive the turnover boxes loaded with materials transported by the conveying mechanism. The turnover boxes can slide automatically along the slide. The lower slide 3 is used to receive the turnover boxes transferred from the floating material platform 5 and transport them to the next work station to realize the recycling of the turnover boxes. The material handling unit 102 is equipped with a traction mechanism 4, the output end of which is connected to a floating material platform 5 that cooperates with the upper slide 2 and the lower slide 3. The traction mechanism 4 drives the floating material platform 5 to move back and forth between the upper slide 2 and the lower slide 3. Under the traction of the traction mechanism 4, the floating material platform 5 is initially located adjacent to and parallel to the upper slide 2, used to receive turnover boxes sliding down from the upper slide 2, providing a stable material handling platform for the workers. After material handling, the floating material platform 5 falls to the lower slide 3. During this process, the floating material platform 5 connects with both the upper slide 2 and the lower slide 3. Below the floating material platform 5 is a limiting mechanism 6 adjacent to the lower slide 3, which is rotatably connected to the material handling unit 102.

[0024] Specifically, the handling mechanism sequentially moves the material-loaded turnover boxes to the upper slide table 2, where they slide into the floating material platform 5. Workers stand beside the material rack 1 to retrieve the materials. After the turnover boxes are empty, the worker activates the traction mechanism 4, which releases the turnover boxes, causing them to fall to the lower limiting mechanism 6. The limiting mechanism 6 is rotatably connected to the material-retrieving part 102, enabling it to receive and limit the turnover boxes and change their tilt angle, tilting them towards the lower slide table 3. Under the new tilt angle and gravity, the turnover boxes automatically slide into the lower slide table 3 and continue sliding along it to the next workstation, completing one full turnover cycle. Through the coordination of the upper slide table 2, lower slide table 3, traction mechanism 4, floating material platform 5, and limiting mechanism 6, automatic cyclic transfer of turnover boxes on the material rack 1 is achieved, eliminating the need for manual handling, saving labor costs, and improving material transfer efficiency. Workers only need to retrieve materials from the floating material platform 5, eliminating the need to move turnover boxes up and down, thus reducing labor intensity and improving the safety of manual operations.

[0025] Furthermore, the traction mechanism 4 includes a traction drive unit 401 disposed at the top of the material handling section 102, at least one guide wheel 402, and a traction rope (not shown in the figure). The output shaft of the traction drive unit 401 is equipped with a drive wheel. One end of the traction rope is connected to the drive wheel, and the other end is connected to the floating material platform 5 via the guide wheel 402. Specifically, the guide wheel 402 is used to change the direction of the traction rope and is staggered in height from the drive wheel, optimizing the routing of the traction rope and guiding the traction rope to drive the floating material platform 5 to move. In this embodiment, the traction drive unit 401 is a drive device including but not limited to a servo motor.

[0026] Furthermore, the limiting mechanism 6 includes a base plate 601 and a limiting rod 602 fixed to the material handling section 102, as well as a receiving plate 603 that supports the floating material platform 5. The receiving plate 603 is rotatably connected to the base plate 601, and the limiting rod 602 cooperates with the receiving plate 603 to limit its movement. The limiting rod 602 and the receiving plate 603 cooperate to achieve a hard limit on the turnover box, ensuring that the turnover box can accurately tilt and slide towards the lower slide table 3.

[0027] Specifically, two support shaft seats 604 are symmetrically arranged on the base plate 601, and a support shaft 605 is provided between the two support seats. A connecting block 606 is rotatably connected to the support shaft 605, and the connecting block 606 is connected to the bottom surface of the receiving plate 603.

[0028] Furthermore, the height of the limiting rod 602 is greater than the height of the connecting block 606. When the turnover box falls, it generates a downward impact force on the receiving plate 603, causing the receiving plate 603 to rotate around the support shaft 605 under the action of this impact force. The limiting rod 602 blocks and holds the receiving plate 603, causing the turnover box to tilt in the opposite direction under the reaction force of the impact force and the limiting rod 602, forming an inclination angle towards the lower slide 3. This ensures that the turnover box can accurately slide into the lower slide 3, improving the accuracy and stability of the turnover box transfer.

[0029] Furthermore, at least one buffer block 607 is symmetrically provided on both sides of the base plate 601, which plays a role in buffering and shock absorption when the turnover box falls onto the receiving plate 603.

[0030] Specifically, the upper slide 2, the lower slide 3, and the floating material platform 5 are symmetrically equipped with slide rails, and the slide rails are equipped with several rollers that cooperate with the turnover box, which reduces the resistance encountered by the turnover box during the sliding process.

[0031] Furthermore, the traction mechanism 4 also includes an operating platform 7 and a control system mounted on the material handling section 102. The operating platform 7 has an emergency stop switch and push-button switches on its surface, which are electrically connected to the control system. The control system is electrically connected to the traction drive unit 401. Operators send commands to the control system via the push-button switches on the operating platform 7. Upon receiving the commands, the control system controls the traction drive unit 401 to perform corresponding actions, such as starting, stopping, or adjusting the running speed, thereby controlling the movement of the floating material platform 5. In case of an emergency, operators can immediately press the emergency stop switch to interrupt equipment operation.

[0032] Specifically, the material rack 1 is equipped with casters 8 at the four corners of its bottom to facilitate the easy transfer of the material rack 1 between different workstations.

[0033] The working process of this utility model is as follows: The conveying mechanism sequentially transports the turnover boxes loaded with materials to the upper slide table 2. Under the action of gravity, the turnover boxes slide along the upper slide table 2 and enter the floating material platform 5. The operator stands next to the material rack 1 and takes the materials from the turnover boxes from the floating material platform 5. When the materials in the turnover boxes are used up, the operator starts the traction mechanism 4 through the operating table 7. The traction drive unit 401 operates and releases the turnover boxes, causing them to fall to the lower limiting mechanism 6. Under the impact of the turnover boxes' gravity, the receiving plate 603 of the limiting mechanism 6 rotates around the support shaft 605. The limiting rod 602 holds the receiving plate 603 in place through a hard limit, causing the turnover boxes to tilt in the opposite direction, towards the lower slide table 3. Under its own gravity, the turnover boxes slide along the receiving plate 603 into the lower slide table 3 and continue to slide along the lower slide table 3 to enter the next work station. Subsequently, the traction drive unit 401 drives the floating material platform 5 back to its initial position, waiting to receive the next batch of turnover boxes, thus realizing the automatic circulation of turnover boxes.

[0034] In this invention, the automatic cyclic transfer of turnover boxes on the material rack 1 is achieved through the cooperation of the upper slide 2, lower slide 3, traction mechanism 4, floating material platform 5, and limiting mechanism 6, eliminating the need for manual handling, saving labor costs, and improving material transfer efficiency. Workers only need to retrieve materials from the floating material platform 5, without having to lift the turnover boxes up and down, reducing labor intensity and improving the safety of manual operations. The limiting rod 602, in conjunction with the receiving plate 603, provides a hard limit on the turnover box. The limiting rod 602 blocks and presses against the receiving plate 603, causing the turnover box to tilt in the opposite direction under the impact force and the reaction force of the limiting rod 602, forming an inclination angle towards the lower slide 3. This ensures that the turnover box can accurately slide into the lower slide 3, improving the accuracy and stability of turnover box transfer.
