Description

Technical Field

[0001] This utility model relates to the field of material conveying and transfer technology, and in particular to an automatic loading and unloading turtle-back vehicle device. Background Technology

[0002] In recent years, with the rapid development of my country's economy, large-scale domestic industries have gradually moved towards automated production lines, and automatic transfer devices for materials (raw materials, semi-finished products, finished products, etc.) have developed rapidly.

[0003] Especially at the beginning of the production line, raw materials are often placed on pallets, and then transported over long distances using a turtleback truck, or transferred between workshops. However, the traditional method mostly involves using forklifts or overhead cranes to lift the pallets carrying materials onto or off the turtleback truck in the vicinity of the truck. This requires forklifts or overhead cranes, as well as manual operation, increasing equipment investment and making production time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an automatic loading and unloading device for a tortoise-back cart, which solves the long-standing problem that materials at the beginning and end of each production line cannot be automatically loaded and unloaded from the tortoise-back cart, and helps to improve production efficiency.

[0005] To achieve the above objectives, this utility model provides an automatic loading and unloading device for a turtle-back vehicle, comprising a main body, auxiliary supports that are detachably installed on both sides of the main body, and guide rods that are detachably installed on the auxiliary supports;

[0006] Multiple support components are detachably installed on the upper back plate of the main body of the device, and the multiple support components are symmetrically arranged and cooperated with each other in pairs. A roller is rotatably installed between two support components, and the roller is driven to rotate by a sprocket transmission assembly.

[0007] The sprocket drive assembly includes sprockets and a reducer. Multiple sprockets are detachably mounted on one side of multiple idler rollers. Adjacent idler rollers are connected in series by a mating chain. The reducer is mounted on the frame of the main body of the device, and the mating sprocket on its output shaft is connected to the sprocket of one of the idler rollers by a transmission chain.

[0008] It also includes a positioning component, which is disposed on one side of the device body to prevent the material pallet from extending beyond the device body.

[0009] The outer surface of each of the rollers is provided with a tungsten carbide coating with a thickness of 0.55 mm.

[0010] The support member uses a seated bearing and is equipped with a locking screw.

[0011] The positioning component includes a collision-resistant buffer block and a photoelectric proximity switch. The fixing bracket of the collision-resistant buffer block is connected to the frame of the main body of the device by bolts. The photoelectric proximity switch is disposed on the fixing bracket of the collision-resistant buffer block and located below the collision-resistant buffer block.

[0012] The transmission mechanism, consisting of multiple idlers, is symmetrically arranged on the upper back plate of the main body of the device.

[0013] This utility model discloses an automatic loading and unloading turtle-back cart device. When the reducer rotates forward, the drive chain pulls the connected sprockets and idlers to rotate, and then drives the remaining idlers to rotate through the cooperating chain. When the material pallet is transported by the conveyor in the previous process, the idlers rotate and carry the material pallet onto the main body of the device. Then the turtle-back cart moves, carrying the main body of the device and the material pallet to the designated position. After reaching the position, the reducer reverses, and the idlers rotate in the opposite direction, leading the material pallet out of the main body of the device. By setting guide rods, the device can automatically guide the material pallet as it enters. The device is aligned with the correct orientation and equipped with a speed reducer to drive the rollers to rotate, guiding the material pallet into or out of the tortoise-back cart. This enables the material pallet to automatically load and unload onto the tortoise-back cart, greatly improving work efficiency. This invention adopts a scheme of multiple sets of rollers arranged in parallel and sprocket drive. The main body of the device is fixed to the back of the tortoise-back cart by four support legs. After installation, the speed reducer is recessed into the frame of the tortoise-back cart, and the material pallet can be loaded and unloaded by the forward and reverse rotation of the speed reducer. This solves the long-standing problem that materials at the beginning and end of each production line cannot be automatically loaded and unloaded onto the tortoise-back cart, and helps to improve production efficiency.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of the automatic loading and unloading device for the turtle-back vehicle. Figure 2 This is a structural schematic diagram of guide rod 5. Figure 3 This is a schematic diagram showing the installation location of speed reducer 7. Figure 4 This is a schematic diagram of the installation position of sprocket 13. This utility model provides an automatic loading and unloading device for a tortoise-back cart: it includes a main body 1, an auxiliary support 3, a guide rod 5, a support component 12, a roller 4, a sprocket 13, a reducer 7, a cooperating chain 9, a transmission chain 10, and a positioning component. The positioning component includes an anti-collision buffer block 6 and a photoelectric proximity switch 8. This solution solves the long-standing problem of materials not being automatically loaded and unloaded from the tortoise-back cart at the beginning and end of production lines, and improves production efficiency. It is understood that this solution enables automatic loading and unloading of material pallets from and from the tortoise-back cart, thus improving production efficiency.

[0022] In this embodiment, the bottom of the main body 1 of the device is fixed to the back of the turtleback vehicle by four support legs. After installation, the reducer 7 is recessed into the frame of the turtleback vehicle for obstacle avoidance and movement protection. (See attached...) Figure 1 Looking at the center, the side with the arrow pointing towards the idler roller 4 is the material feed side of the pusher plate.

[0023] Auxiliary supports 3 are detachably installed on both sides of the main body 1 of the device, and guide rods 5 are detachably installed on the auxiliary supports 3. Multiple auxiliary supports 3 are fixed to the main body 1 of the device with bolts, and the guide rods 5 are fixed to the auxiliary supports 3 with countersunk bolts. The guide rods 5 are paired and can slide with both sides of the pallet during material pallet transport, serving as a limit for lateral movement during pallet transport. By setting the guide rods 5, the device can automatically align itself when the material pallet enters, and the reducer 7 drives the idler rollers 4 to rotate, guiding the material pallet into or out of the turtle-back cart. This achieves automatic loading and unloading of the material pallet onto and off the turtle-back cart, greatly improving work efficiency.

[0024] Multiple support members 12 are detachably installed on the upper back plate of the main body 1 of the device, and the multiple support members 12 are symmetrically arranged and cooperated with each other in pairs. A roller 4 is rotatably installed between two support members 12, and the roller 4 is driven to rotate by a sprocket transmission assembly. The multiple support members 12 are fixed by bolts for supporting the rotation of the roller 4, and the sprocket transmission assembly is used to drive the multiple rollers 4 to rotate.

[0025] The sprocket drive assembly includes sprockets 13 and a reducer 7. Multiple sprockets 13 are detachably mounted on one side of multiple idler rollers 4. Adjacent idler rollers 4 are connected in series via a mating chain 9. The reducer 7 is mounted on the frame of the main body 1, and its output shaft has a mating sprocket connected to the sprocket 13 of one of the idler rollers 4 via a transmission chain 10. The sprocket 13 is fixed to the end of the idler roller 4 by a flat key and secured by bolts on its outer ring. The reducer 7's mounting base is connected to the frame of the main body 1 by bolts. A mating sprocket is mounted on its output shaft via a flat key and a T-shaped tensioning disc. The mating sprocket is connected to the sprocket 13 of one of the idler rollers 4 via the transmission chain 10.

[0026] The positioning component is disposed on one side of the device body 1 to prevent the material pallet from extending beyond the device body 1. The positioning component enables the material pallet to be accurately positioned when it is being transported onto the turtle-back cart, preventing the pallet from moving out of the turtle-back cart.

[0027] Secondly, the outer surface of each of the rollers 11 of the plurality of idlers 4 is provided with a tungsten carbide coating with a thickness of 0.55 mm. This structure helps to extend the service life of the idlers 4 during long-term contact with the material pallet.

[0028] Then, the support member 12 adopts a mounted bearing and is equipped with a locking screw. A mounted bearing is a type of mechanical component that combines a bearing and a mounting base, mainly used to fix and support the rotating shaft. It is suitable for transmission, conveying, and speed reduction devices in both heavy and light industries. Its core features include convenient pre-assembly, self-aligning function, and multiple shaft connection methods. The locking screw is used to abut against the mounting shaft end surface of the idler roller 4 after installation for mounting and mating.

[0029] Furthermore, the fixed bracket of the anti-collision buffer block 6 is connected to the frame of the main body 1 of the device by bolts; the photoelectric proximity switch 8 is mounted on the fixed bracket of the anti-collision buffer block 6 and located below the anti-collision buffer block 6. The anti-collision buffer block 6 is provided with a fixed bracket, which is fixed by bolts, and the photoelectric proximity switch 8 is mounted on the fixed bracket. The photoelectric proximity switch 8 is a diffuse reflection infrared photoelectric switch used to detect the position of the material pallet conveying. When it detects a pallet signal, the reducer 7 will stop operating.

[0030] Finally, a transmission mechanism consisting of multiple idler rollers 4 is symmetrically arranged on the upper back plate of the main body 1 of the device. This structure is capable of forming a dual-station loading and unloading conveyor structure.

[0031] When using this utility model to automatically load and unload material pallets onto a turtle-back cart and improve production efficiency, firstly, the corresponding components of the main body 1 are assembled, and the main body 1 is installed on the turtle-back cart. When the reducer 7 rotates forward, it drives the sprocket on its output shaft to rotate. The traction of the transmission chain 10 drives the sprocket 13 and the idler roller 4 connected to it to rotate. Then, the connecting chain 9 drives the other idler rollers 4 to rotate. When the material pallet is transported by the conveyor in the previous process, the idler roller 4 rotates and carries the material pallet onto the main body 1. The photoelectric proximity switch 8 detects the pallet position, and after it reaches the designated position, it... When the reducer 7 stops operating, the turtle-back cart moves, carrying the main body 1 of the device and the material pallet to the designated position. After reaching the position, the reducer 7 reverses, and multiple idler rollers 4 rotate in the opposite direction, leading the material pallet out of the main body 1 of the device. This utility model adopts a scheme of multiple sets of idler rollers 4 arranged in parallel and sprocket drive. The main body 1 of the device is also fixed to the back of the turtle-back cart by four support legs. After installation, the reducer 7 is sunk into the frame of the turtle-back cart, and the automatic loading and unloading of the material pallet is realized by the forward and reverse rotation of the reducer 7. This solves the long-standing problem that materials at the beginning and end of each production line cannot be automatically loaded and unloaded from the turtle-back cart, and helps to improve production efficiency.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
