Abstract
Description
Technical Field
[0001] This utility model relates to an automatic loading and unloading device. Background Technology
[0002] Automated loading and unloading devices enable continuous workpiece loading and unloading. Compared to manual loading and unloading, they are not limited by factors such as fatigue or rest, and can work 24 hours a day without interruption. For example, in a bearing component processing production line, an automated loading and unloading device can complete the loading and collection of a large number of parts in a short time, greatly shortening the processing cycle of a single workpiece. In the existing production process, partially completed materials are collected in hoppers, then the hoppers are batched together and then dumped for subsequent processing steps. The existing equipment has a relatively cumbersome structure, low automation level, reduced production efficiency, and high labor costs, which is not conducive to improving enterprise efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an automatic loading and unloading device with a simple structure, high degree of automation, and effective loading and unloading operations, resulting in high production and processing efficiency.
[0004] To achieve the above objectives, this utility model provides an automatic loading and unloading device, comprising a support frame, a conveyor frame, a transfer rail, and a tilting frame arranged sequentially. Lifting rails are respectively provided on both sides of the support frame. A lifting member is slidably fitted on the lifting rails. The lifting member is equipped with a drive wheel and a drive motor for the drive wheel to slide along the lifting rails. The drive wheel is slidably fitted with the lifting rails. The lifting member is equipped with a lifting arm and a lifting motor for driving the lifting arm to swing. One end of the lifting arm is rotatably connected to the lifting member, and the other end is bent outwards from the support frame and equipped with a railing to prevent the container from falling from the side. The conveyor frame is equipped with a support protrusion for inserting into the bottom of the cargo box. Conveyor belts are respectively provided on both sides of the conveyor frame. A slide rail is provided between the conveyor belts on the conveyor frame. The slide rail extends into the support frame. A conveyor trolley is slidably fitted on the slide rail. A transfer rail is provided along the width direction of the conveyor frame. A transfer trolley is slidably provided on the transfer rail. A first conveyor belt is provided on the transfer trolley along the length direction of the conveyor frame. A second conveyor belt is provided on the tilting frame along the length direction of the conveyor frame. The first conveyor belt, the second conveyor belt and the conveyor belt are set at the same height. A tilting hopper is provided on the tilting frame for driving the cargo box to rise and rotate at least 90°.
[0005] The advantages of this setup are as follows: With this configuration, a forklift stacks the material containers onto the support frame. A conveyor trolley on the conveyor frame then approaches, using lifting mechanisms to raise the containers so the trolley is positioned beneath them. The lifting mechanism then places the stacked containers onto the trolley, leaving one container unattended. A support protrusion is inserted into the bottom of the unattended container, and a railing abuts against the side wall of the container, limiting its movement and preventing accidental detachment. This allows the remaining containers to be lifted. The conveyor trolley then transports one container into the conveyor frame, while the conveyor belt on the frame carries the remaining containers... The container is removed from the conveyor and sent to the other end of the conveyor frame. The transfer car at the other end of the conveyor frame receives the container and is fed into the tipping hopper by the first conveyor belt. At the same time, the tipping hopper is driven to perform a tipping action to realize the dumping and collection of materials. After the tipping is completed, the container is sent back to the transfer car by the second conveyor belt. The transfer car slides away along the transfer rail, thus sending out the empty container, completing the entire automatic loading and unloading operation. This structure can work continuously, reducing the time interval of manual loading and unloading, speeding up the production process, improving equipment utilization, and reducing the labor intensity of workers. At the same time, it avoids errors caused by repetitive operations and reduces the company's labor costs.
[0006] As a further feature of this utility model, the tipping hopper includes a supporting wall and surrounding walls disposed on both sides of the supporting wall. The bottom surfaces of the surrounding walls and the supporting walls are respectively provided with supporting ribs for supporting the cargo box. The outer wall of the surrounding walls is provided with a first guide flange and a second guide flange. The tipping frame is provided with a first guide groove along the height direction. The first guide flange slides in conjunction with the first guide groove. The tipping frame is also provided with a second guide groove that is arc-shaped. The second guide flange slides in conjunction with the second guide groove.
[0007] The beneficial effects of this design are as follows: With this configuration, the supporting wall, as the main load-bearing component, works in conjunction with the surrounding walls on both sides. The supporting ribs on the bottom of both precisely support the loading box, ensuring its stability during the flipping process and greatly reducing the risk of material spillage due to shaking and displacement. The first and second guide flanges, in close cooperation with the first guide groove along the height direction and the arc-shaped second guide groove on the flipping frame, provide stable vertical guidance for the flipping hopper by sliding along the first guide groove, effectively preventing vertical deviation. Furthermore, the sliding cooperation between the second guide flange and the arc-shaped second guide groove ensures that the flipping hopper moves precisely along a predetermined arc trajectory during the flipping action, avoiding deviation. This comprehensive design ensures the stability of the flipping process, enabling reliable operation in both high-speed industrial production lines and precision-critical material handling processes. It significantly improves the overall structural reliability, reduces equipment failure rates, and increases production efficiency.
[0008] As a further feature of this invention, the supporting wall and the surrounding wall are provided with continuous guards for preventing the cargo box from falling out.
[0009] The beneficial effects of this design are as follows: the continuous guards on the supporting wall and the surrounding wall play an indispensable protective role. When the tipping hopper undergoes rapid tilting, violent shaking, or complex acceleration and deceleration, the loading box is prone to displacement due to inertia. In this situation, the continuous guards effectively and tightly fit against the edges of the supporting wall and the surrounding wall, comprehensively restricting the loading box's range of motion. Whether in frequently starting and stopping automated production lines or in special operating conditions involving sudden vibrations and impacts, the guards effectively prevent the loading box from accidentally falling out, ensuring the integrity of material transportation, reducing material loss, maintaining the normal operation of the production line, and further improving the overall stability and reliability of the equipment.
[0010] As a further feature of this utility model, the support frame is configured as two, namely a first support frame and a second support frame, the first support frame is located at the beginning of the conveyor frame, and the second support frame is located at the end of the transfer rail.
[0011] The beneficial effects of this setup are as follows: A second support frame positioned at the end of the final transfer rail can collect empty containers. After materials are transported along the conveyor and the processing steps are completed, the containers become empty. At this point, the second support frame acts as a precise collection station, orderly gathering the empty containers and preventing them from scattering and disrupting the smooth operation of the production line. This not only makes the workshop area cleaner and reduces the risk of obstruction to personnel and equipment collisions caused by haphazardly placed empty containers, but also facilitates the subsequent unified disposal of empty containers, greatly simplifying recycling and cleaning processes and significantly optimizing the overall management efficiency of the production line.
[0012] As a further feature of this utility model, the first support frame is provided with a platform on each side for placing the cargo box at the four corners, and the upper surface of the conveyor is higher than the platform.
[0013] The advantages of this design are as follows: The platform is precisely positioned to support the four corners of the cargo box, cleverly pre-raising it. Since the top of the conveyor is higher than the platform, the cargo box does not require excessive energy for large-scale lifting and lowering movements during transitions. This effectively reduces the workload of the lifting device, lowers energy consumption, and extends its service life. Furthermore, it accelerates material flow and improves conveying efficiency. Especially in large-scale, high-intensity production scenarios, this provides strong support for enterprises to save energy, increase efficiency, and enhance market competitiveness.
[0014] As a further feature of this invention, a third conveyor belt is provided in the second support frame along the length of the conveyor frame, and the third conveyor belt and the conveyor belt are arranged at the same height.
[0015] The advantages of this setup are as follows: With the third conveyor belt at the same height as the main conveyor belt, the transfer of cargo boxes between them is extremely smooth, eliminating the need for additional height adjustments. This effectively avoids potential jams and collisions caused by height differences, significantly improving transfer efficiency. Furthermore, this directional layout is more compact, saving valuable workshop space and allowing room for the movement of other equipment and personnel. It also optimizes material transport paths, reducing unnecessary detours and further accelerating the overall production pace, bringing numerous conveniences to the company.

The beneficial effects of this setup are as follows: With this setup, a forklift stacks the material containers onto the support frame. At this time, the conveyor trolley 22 on the conveyor frame 2 moves in and approaches, lifting the containers using the lifting member 5 so that the conveyor trolley 22 is positioned below the containers. The lifting member 5 then places the stacked containers onto the conveyor trolley 22. Simultaneously, the lifting member 5 moves upward, leaving one container unattended, and inserts the support protrusion 54 into the bottom of the container. Meanwhile, the railing 53 abuts against the side wall of the container, limiting its movement and preventing accidental detachment. This also supports the remaining containers. The conveyor trolley 22 then transports one container into the conveyor frame 2, and the conveyor belt 21 on the conveyor frame 2... The loading box is taken away from the conveyor 22 and sent to the other end of the conveyor frame 2. The transfer car 31 located at the other end of the conveyor frame 2 takes the loading box and sends it into the tipping hopper 6 by the first conveyor belt 32. At the same time, the tipping hopper 6 is driven to perform a tipping action to realize the dumping and collection of materials. After the tipping is completed, the loading box is sent back to the transfer car 31 by the second conveyor belt 41. The transfer car 31 slides away along the transfer rail 3, thereby sending out the empty box and completing the entire automatic loading and unloading action. This structure can work continuously, reduce the time interval of manual loading and unloading, speed up the production process, improve equipment utilization, and reduce the labor intensity of workers. At the same time, it avoids errors caused by repetitive operations and reduces the labor costs of enterprises.
[0025] As a further feature of this invention, the tipping hopper 6 includes a supporting wall 61 and surrounding walls 62 disposed on both sides of the supporting wall 61. The bottom surfaces of the surrounding walls 62 and the supporting wall 61 are respectively provided with supporting ribs 63 for supporting the cargo box.

The tipping frame 4 is also provided with a second guide groove 43 arranged in an arc shape, and the second guide flange 65 slides into the second guide groove 43. The beneficial effect of this configuration is that the supporting wall 61, as the main supporting component, works in conjunction with the surrounding walls 62 on both sides. The supporting ribs 63 on the bottom surfaces of both precisely support the cargo box, ensuring the stability of the cargo box during tipping and greatly reducing the risk of material spillage due to shaking and displacement. The first guide flange 64 and the second guide flange 65, through their structure, closely cooperate with the first guide groove 42 along the height direction and the arc-shaped second guide groove 43 on the tipping frame 4. On the one hand, the first guide flange 64 slides along the first guide groove 42, providing stable vertical guidance for the tipping hopper 6 and effectively preventing it from deviating in the vertical direction. On the other hand, the sliding cooperation between the second guide flange 65 and the arc-shaped second guide groove 43 allows the tipping hopper 6 to move precisely along a predetermined arc trajectory during the tipping action, avoiding deviation. This comprehensively ensures the stability of the tipping process, enabling reliable operation in both high-speed industrial production lines and material handling processes with stringent precision requirements.

[0026] As a further feature of this invention, continuous baffles 66 are provided on the supporting wall 61 and the surrounding wall 62 to prevent the container from falling out. The beneficial effect of this design is that the continuous baffles 66 on the supporting wall 61 and the surrounding wall 62 provide indispensable protection. When the tipping hopper 6 undergoes rapid flipping, violent shaking, or complex acceleration and deceleration, the container is prone to displacement due to inertia. At this time, the continuous baffles 66 effectively and tightly fit against the edges of the supporting wall 61 and the surrounding wall 62, comprehensively restricting the movement range of the container. Whether in an automated production line with frequent start-stop cycles or in special working conditions involving sudden vibrations and impacts, the baffles 66 effectively prevent the container from accidentally falling out, ensuring the integrity of material transportation, reducing material loss, maintaining the normal operation of the production line, and further improving the overall stability and reliability of the equipment.

The first support frame 11 is located at the beginning of the conveyor frame 2, and the second support frame 12 is located at the end of the transfer rail 3. The beneficial effect of this configuration is that the second support frame 12 at the end of the transfer rail 3 can collect empty boxes. When materials are transported along the conveyor frame 2 and the processing steps are completed, the boxes become empty. At this time, the second support frame 12 acts as a precise collection station, orderly collecting the empty boxes and preventing them from scattering and interfering with the smooth operation of the production line. This not only makes the workshop area cleaner and reduces the risk of personnel obstruction and equipment collisions caused by haphazardly placed empty boxes, but also facilitates the subsequent unified handling of empty boxes, greatly facilitating recycling or cleaning work and significantly optimizing the overall management efficiency of the production line.
[0028] As a further feature of this invention, the first support frame 11 is provided with platforms 112 on both sides for placing the four corners of the cargo box, and the upper surface of the conveyor 22 is higher than the platforms 112. The advantages of this arrangement are: the platforms 112 are precisely positioned to support the four corners of the cargo box, cleverly pre-raising the cargo box. Since the upper surface of the conveyor 22 is higher than the platforms 112, the cargo box does not require excessive energy for large-scale lifting and lowering movements during transitions. This effectively reduces the workload of the lifting device, lowers equipment energy consumption, and extends its service life; it also accelerates material flow and improves conveying efficiency. Especially in large-scale, high-intensity production scenarios, this provides strong support for enterprises to save energy, increase efficiency, and enhance market competitiveness.
[0029] As a further feature of this invention, a third conveyor belt 121 is provided along the length of the conveyor frame 2 in the second support frame 12. The third conveyor belt 121 and the conveyor belt 21 are at the same height.
