[0002] In today's material handling field, with the continuous development of automated production and efficient logistics, the demand for devices that can continuously, stably and efficiently transport material frames is increasing.

[0003] Traditional material frame conveying methods mostly rely on a single conveying device, such as the common roller conveyor. While this device can achieve the basic function of conveying the material frame from one end to the other, it has many limitations. On the one hand, after the material frame completes one conveying cycle and reaches the end, it often needs to be manually moved back to the starting end by additional complex equipment for the next round of conveying. This not only greatly increases labor costs and equipment investment, but also seriously affects the efficiency and continuity of the entire production or logistics process.

[0004] Some existing conveying systems attempt to improve the backflow problem of the material frame by adding some auxiliary structures, but these structures are usually complex in design, resulting in high manufacturing costs, difficult maintenance, and high energy consumption.

[0005] In view of the shortcomings of these existing technologies, there is an urgent need for an automatic conveying device that can achieve continuous automatic conveying of material frames, smooth return flow, reasonable structure and stable operation, so as to improve production or logistics efficiency, reduce operating costs and adapt to diverse conveying needs.

[0018] The drive roller assembly includes multiple drive rollers spaced apart, and the drive rollers of the drive roller assembly are rotatably connected to the top of the scissor lift platform.

[0019] The synchronous belt consists of two belts, which are installed on both sides of the drive roller assembly to enable the drive rollers of the drive roller assembly to rotate synchronously.

[0020] The drive motor is installed at the bottom of the scissor lift platform and is used to drive the drive rollers of the roller assembly to rotate forward or backward.

[0021] Preferably, a limit block is installed at the top of the scissor lift platform away from the roller conveyor device.

[0022] Preferably, a stop device is installed at the tail end of the roller conveyor; the stop device includes:

[0023] The second telescopic cylinder is fastened to the frame of the roller conveyor; the telescopic rod of the second telescopic cylinder moves vertically up and down.

[0024] A stop plate is installed on the top of the telescopic rod of the second telescopic cylinder.

[0025] Preferably, the roller conveyor is equipped with limit rods on both sides of its top, and a plurality of width adjustment devices for adjusting the distance between the two limit rods; the width adjustment device includes:

[0026] The fixed rod is fastened to the frame of the roller conveyor; a through hole is provided at the top of the rod.

[0027] The adjusting rod has one end that is movably inserted into the through hole of the fixed rod, and the other end that is fastened to the corresponding limiting rod.

[0028] The locking handle is threaded to the top of the fixing rod, and the locking handle can correspond to and abut against the rod body of the adjusting rod located in the through hole of the fixing rod.

[0029] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0030] (1) This utility model has a simple structure. Through the organic combination of roller conveying device, automatic return device and return lifting device, the continuous automatic conveying of the material frame is realized. The roller conveying device uses a motor to drive the conveying roller, which can stably convey the material frame from one end to the other. The automatic return device adopts the form of inclined slide or mounting frame combined with roller shaft, and uses the weight of the material frame itself to make it automatically return, without the need for additional power, saving energy.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] Example 1:

[0044] Combined with appendix Figures 1-3 An automatic conveying device includes a roller conveyor 1, an automatic return device 3, and a return lifting device 4. The roller conveyor 1 is a common, existing device on the market, containing a frame. Multiple conveying rollers are rotatably connected to the top of the frame. The main function of these conveying rollers is to support and convey the material frame 2. The rotation of the conveying rollers is driven by a motor, thereby achieving the function of stably conveying the material frame 2 from one end of the roller conveyor 1 to the other.

[0045] Below the conveying rollers of the roller conveyor 1, an automatic return device 3 is installed. The purpose of this automatic return device 3 is to utilize the weight of the material frame 2 to automatically and smoothly move it from one end of the roller conveyor 1 to the other. In this embodiment, the automatic return device 3 can be implemented using an inclined slide. When the material frame 2 falls onto the automatic return device 3, it will automatically slide from the higher end of the slide to the lower end under its own weight.

[0046] Furthermore, the automatic return device 3 specifically includes a mounting frame 3-1 and a roller 3-2. (See attached diagram.) Figure 3 As shown, the mounting frame 3-1 is securely connected to the frame of the roller conveyor 1, and the mounting frame 3-1 itself is inclined. There are multiple rollers 3-2, each rotatably connected to the mounting frame 3-1. When the material frame 2 falls onto the roller 3-2, it slides along the mounting frame 3-1 from the higher end to the lower end under its own weight. Compared to using a slide rail, this structural design reduces the friction between the material frame 2 and the roller 3-2, effectively preventing the material frame 2 from being obstructed on the automatic return device 3, and significantly increasing the return speed of the material frame 2, thereby improving the overall efficiency of the device.

[0047] In addition, both ends of the roller conveyor 1 are equipped with return lifting devices 4. The main function of the return lifting devices 4 is to realize the mutual transfer of the material frame 2 between the roller conveyor 1 and the automatic return device 3. Specifically, when the material frame 2 moves from the head end to the tail end of the roller conveyor 1, it can smoothly enter the return lifting device 4 at the tail end. At this time, the return lifting device 4 will carry the material frame 2 to descend, transferring the material frame 2 to the higher end of the automatic return device 3. Subsequently, the material frame 2 will automatically move along a predetermined path on the automatic return device 3, returning to the head end of the roller conveyor 1, and entering the return lifting device 4 located at the head end of the roller conveyor 1. At this time, the return lifting device 4 will carry the material frame 2 to rise, transferring it to the head end position of the roller conveyor 1. This cycle repeats, realizing the continuous automatic conveying process of the material frame 2.

[0048] One point that needs special attention is that during the process of the return lifting device 4 at the tail end of the roller conveyor 1 transferring the material frame 2 to the automatic return device 3, the return lifting device 4 at the head end of the roller conveyor 1 needs to be lowered to a low position simultaneously and precisely aligned with the lower end of the automatic return device 3. This ensures that the material frame 2 can slide smoothly and unobstructed onto the return lifting device 4 at the head end of the roller conveyor 1, thereby ensuring the smooth progress of the entire conveying process.

[0049] Example 2:

[0050] Combined with appendix Figure 4 With appendix Figure 5 Based on Embodiment 1, this automatic conveying device further refines and optimizes the structure of the return lifting device 4. Specifically, the return lifting device 4 comprises a scissor lift device 4-1, a first telescopic cylinder 4-2, and a drive roller group 4-3.

[0051] The first telescopic cylinder 4-2 is installed inside the scissor lift device 4-1, and its main function is to drive the lifting platform of the scissor lift device 4-1 to perform lifting operations. Since the scissor lift device 4-1 is a common type of lifting mechanism on the market, its specific working principle will not be elaborated here. (See attached...) Figure 4 and attached Figure 5 As shown, when the first telescopic cylinder 4-2 is in the shortened state, the lifting platform of the scissor lift device 4-1 will descend accordingly; conversely, when the first telescopic cylinder 4-2 is in the extended state, the lifting platform of the scissor lift device 4-1 will rise.

[0052] A drive roller assembly 4-3 is installed at the top of the scissor lift platform 4-1. The drive roller assembly 4-3 consists of multiple spaced drive rollers, which are rotatably connected to the top of the scissor lift platform 4-1. Simultaneously, synchronous belts 4-4 are installed on both sides of the drive roller assembly 4-3, enabling synchronous rotation of all drive rollers in the assembly. Furthermore, a drive motor 4-5 is installed at the bottom of the scissor lift platform 4-1. This drive motor 4-5 is connected to one of the drive rollers in the drive roller assembly 4-3, thus enabling all drive rollers in the assembly to rotate forward or backward.

[0053] When the material frame 2 enters the return lifting device 4, the drive motor 4-5 can drive the roller group 4-3 to rotate forward, allowing the material frame 2 to smoothly and completely detach from the roller conveyor device 1. When it is necessary to transfer the material frame 2 back to the roller conveyor device 1, the drive motor 4-5 can drive the roller group 4-3 to rotate in the opposite direction, thereby detaching the material frame 2 from the drive roller group 4-3, completing the precise transfer process of the material frame 2 between different devices.

[0054] Example 3:

[0055] Combined with appendix Figure 1 and 3 Based on Embodiment 1 or Embodiment 2, this automatic conveying device adds a stop device 5 to the tail end of the roller conveyor 1 to meet the unidirectional conveying requirement that the material frame 2 is usually conveyed from the head end to the tail end of the roller conveyor 1.

[0056] The stopping device 5 specifically includes a second telescopic cylinder 5-1 and a stop plate 5-2. The second telescopic cylinder 5-1 is correspondingly and securely connected to the frame of the roller conveyor 1, and its telescopic rod can achieve vertical lifting and lowering. The stop plate 5-2 is installed at the top of the telescopic rod of the second telescopic cylinder 5-1.

[0057] In actual operation, when the return lifting device 4 at the tail end of the roller conveyor 1 is not yet aligned with the roller conveyor 1, the second telescopic cylinder 5-1 in the stop device 5 will extend, thereby raising the stop plate 5-2. The stop plate 5-2 blocks the material frame 2 from continuing to move forward, effectively preventing the material frame 2 from accidentally tipping over and avoiding it from getting stuck between the tail end of the roller conveyor 1 and the corresponding return lifting device 4, ensuring the safety and stability of the equipment operation. When the return lifting device 4 is aligned with the roller conveyor 1, the second telescopic cylinder 5-1 will shorten, making the stop plate 5-2 lower than the conveyor roller of the roller conveyor 1, thereby releasing the material frame 2 and allowing it to smoothly enter the return lifting device 4 at the tail end of the roller conveyor 1, ensuring a smooth connection of the conveying process.

[0058] Example 4:

[0059] Combined with appendix Figure 1 and 3 Based on any one of the embodiments in Examples 1 to 3, this automatic conveying device optimizes the top structure of the roller conveyor 1. Specifically, limit rods 7 are installed on both sides of the top of the roller conveyor 1, and multiple width adjustment devices 6 are provided. The main function of these width adjustment devices 6 is to adjust the distance between the two limit rods 7, so that the distance between the two limit rods 7 can be flexibly adjusted according to the material frame 2 of different width specifications, effectively avoiding the phenomenon of arbitrary tilting of the material frame 2 during the conveying process, and ensuring the stability and accuracy of the conveying process.

[0060] In detail, the width adjustment device 6 comprises a fixed rod 6-1, an adjusting rod 6-2, and a locking handle 6-3. The fixed rod 6-1 is securely connected to the frame of the roller conveyor 1, and its top has a through hole. One end of the adjusting rod 6-2 is movably connected to the through hole of the fixed rod 6-1, while the other end is securely connected to the limiting rod 7. A locking handle 6-3 is threaded onto the top of the fixed rod 6-1, and its lower end can extend into the through hole of the fixed rod 6-1. When it is necessary to lock the adjusting rod 6-2, the locking handle 6-3 abuts against the rod body of the adjusting rod 6-2 located within the through hole of the fixed rod 6-1, thereby fixing the position of the adjusting rod 6-2.

[0061] When it is necessary to adjust the distance between the two limit rods 7, the operator can first loosen the corresponding locking handle 6-3, and then adjust the position of the limit rod 7 by pushing the adjusting rod 6-2. After adjusting to the appropriate position, tighten the locking handle 6-3 to complete the adjustment. This adjustment method has the advantages of simple operation and high adjustment efficiency, and can quickly adapt to the conveying needs of different specifications of material frames 2, greatly enhancing the versatility and practicality of this automatic conveying device.

[0062] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
