[0001] This utility model relates to the field of sorting equipment technology, and in particular to a reversing device and a defective product unloading system. Background Technology

[0002] During product manufacturing, there may be situations where good and defective products are transported simultaneously. Defective products must be removed and unloaded to ensure customer satisfaction after product delivery. The removal of defective products on the production line is usually affected by the spatial layout. Materials that need to be removed must be redirected after leaving the conveyor belt and then enter a waiting position for manual inspection and processing.

[0003] Existing production line steering devices are only compatible with steering of a single product specification (large, medium, or small), or rely on bend guardrails for steering. When defective products are continuously rejected, the material to be rejected accumulates at the bend, causing squeezing or collision, which will wear down the corners and edges of the material to be rejected, affecting the perfection of the product.

[0004] Therefore, there is an urgent need for a reversing device and a defective product unloading system to solve the above problems. Utility Model Content

[0005] According to one aspect of the present invention, a reversing device is provided, which can reverse the conveying of materials to be rejected, prevent the materials from accumulating and causing squeezing and collision, and realize continuous feeding one by one by detecting the feeding information of the materials to be rejected.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The reversing device includes:

[0008] A conveying assembly, wherein the feeding end of the conveying assembly is connected to the defective product rejection station of the production line, and the material to be rejected is conveyed from the defective product rejection station to the feeding end, and the conveying assembly can drive the material to be rejected to move along a first direction;

[0009] The stop assembly includes a guardrail portion and a rotating portion. The guardrail portion is disposed at the far end of the conveying assembly in a first direction and extends along a second direction, which forms an angle with the first direction. The rotating portion is rotatably disposed on the guardrail portion and can roll in cooperation with the side of the material to be rejected, so that the material to be rejected moves along the second direction to the unloading end of the conveying assembly under the drive of the conveying assembly.

[0010] A material detection device is disposed on the side of the guardrail near the feeding end, and the material detection device is configured to detect the feeding information of the material to be rejected at the feeding end.

[0011] Optionally, the first direction is perpendicular to the second direction.

[0012] Optionally, the conveying assembly includes a Mecanum wheel conveyor, which includes a rotating shaft and a plurality of Mecanum wheels rotatably connected to the rotating shaft, the rotating shaft extending in a direction perpendicular to the first direction.

[0013] Optionally, multiple wheat wheel conveyors are provided, and the rotation shafts of the multiple wheat wheel conveyors are spaced apart along a first direction.

[0014] Optionally, the conveying assembly further includes a roller conveyor disposed upstream of the wheat wheel conveyor in a first direction, wherein the axis of rotation of the roller conveyor is parallel to the axis of rotation of the wheat wheel conveyor.

[0015] Optionally, the reversing device further includes a multi-ribbed belt drive assembly, through which the wheat wheel conveyor and the roller conveyor are connected.

[0016] Optionally, the rotating part includes a plurality of rollers arranged along the second direction, the rotation axis of the rollers being perpendicular to both the first and second directions.

[0017] Optionally, the reversing device further includes a support frame, which includes a first support plate and a second support plate. The first support plate and the second support plate are spaced apart in a direction perpendicular to the first direction and are respectively connected to both sides of the conveying assembly. The two ends of the guardrail are respectively connected to the first support plate and the second support plate.

[0018] Optionally, the reversing device further includes a control module, which is communicatively connected to the conveying component and the material detection component. The control module can control the start and stop of the conveying component based on the feeding information received from the material detection component.

[0019] According to another aspect of the present invention, a defective product unloading system is provided, including a defective product detection station and a reversing device as described in any of the above claims, wherein the loading end of the conveying component is connected to the defective product rejection station on the production line, and the unloading end of the conveying component is connected to the defective product detection station.

[0020] The beneficial effects of this utility model are:

[0021] The reversing device provided by this utility model includes a conveying component, a stop component, and a material detection component. The feeding end of the conveying component is connected to the defective product rejection station on the production line, facilitating the transport of materials to be rejected from the rejection station to the feeding end. Simultaneously, the conveying component can drive the material to be rejected to move along a first direction. When the material to be rejected moves to abut against the rotating part on the guardrail, it can also move along a second direction to the unloading end of the conveying component under the drive of the conveying component. The second direction forms an angle with the first direction, thereby realizing the reversing transport of the material to be rejected. Furthermore, due to the rolling engagement between the rotating part and the side of the material to be rejected, friction is effectively reduced, minimizing wear on the side of the material and ensuring the aesthetic appearance of the product.

This component is configured to detect the feeding information of materials to be rejected at the feeding end. In other words, the material detection component can detect whether there are materials to be rejected at the feeding end. Only after the materials to be rejected at the feeding end have been successfully fed will the conveying assembly continue to convey new materials to be rejected. This ensures that there is no material accumulation at the feeding end, avoids jamming, and achieves continuous feeding one by one. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] This embodiment provides a reversing device and a defective product unloading system. The defective product unloading system includes a defective product detection station and the reversing device provided in this embodiment. The loading end of the reversing device is connected to the defective product rejection station on the production line, and the unloading end of the reversing device is connected to the defective product detection station, thereby transferring the materials to be rejected (i.e., defective products, unqualified products) from the production line to the defective product detection station, where they are inspected manually or otherwise.

[0043] Specifically, a rejection electric cylinder is installed at the defective product rejection station on the production line. The rejection electric cylinder can push the material to be rejected on the production line and reject it to the feeding end of the reversing device.

[0044] like Figure 1 As shown, the reversing device provided in this embodiment includes a conveying component 1, a stop component 2, and a material detection component 3.

[0045] The feeding end 11 of the conveying assembly 1 is connected to the defective product rejection station of the production line. The material to be rejected is conveyed from the defective product rejection station to the feeding end 11. The conveying assembly 1 can drive the material to be rejected to move along a first direction. The stop assembly 2 includes a guardrail part 21 and a rotating part 22. The guardrail part 21 is located at the far end of the conveying assembly 1 in the first direction and extends along a second direction, which forms an angle with the first direction. The rotating part 22 is rotatably mounted on the guardrail part 21. The rotating part 22 can roll in cooperation with the side of the material to be rejected, so that the material to be rejected moves along the second direction to the unloading end of the conveying assembly 1 under the drive of the conveying assembly 1.

[0046] In other words, the feeding end 11 of the conveying component 1 is the feeding end of the reversing device, and the discharging end of the conveying component 1 is the discharging end of the reversing device. The feeding end 11 of the conveying component 1 is connected to the defective product rejection station of the production line, so that the materials to be rejected on the production line can be conveyed from the defective product rejection station to the feeding end 11. At the same time, the conveying component 1 can drive the materials to be rejected to move in the first direction. When the materials to be rejected move to abut against the rotating part 22 on the guardrail part 21, the materials to be rejected can also move in the second direction to the discharging end of the conveying component 1 under the drive of the conveying component 1, thereby realizing the reversing transport of the materials to be rejected. Furthermore, since the rotating part 22 and the side of the materials to be rejected roll together, the friction can be effectively reduced, the wear on the side of the materials to be rejected can be reduced, and the aesthetic appearance of the product can be guaranteed.

[0047] Preferably, in this embodiment, the first direction is perpendicular to the second direction. This arrangement enables 90° turning conveying of materials to be rejected, adapting to the spatial layout constraints of the production line and making efficient use of space.

[0048] like Figure 1 and Figure 2As shown, the conveying assembly 1 includes a Mecanum wheel conveyor 12, which includes a rotating shaft 121 and multiple Mecanum wheels 122 rotatably connected to the rotating shaft 121. The extension direction of the rotating shaft 121 is perpendicular to a first direction. The Mecanum wheel 122 is an omnidirectional wheel, based on the principle of a central wheel with many axles located around its periphery. These angled peripheral axles convert a portion of the wheel's steering force into a wheel's normal force. Depending on the direction and speed of each wheel, the final resultant force vector of these forces produces a resultant force vector in any desired direction, ensuring that the platform can move freely in the direction of the final resultant force vector without changing the wheel's own orientation. Many small rollers are obliquely distributed on its rim, allowing the wheel to slide laterally. The generatrix of the small rollers is special; when the wheel rotates around a fixed central shaft, the envelope of each small roller is a cylindrical surface, allowing the wheel to roll continuously forward. The Mecanum wheel 122 has advantages such as compact structure and flexible movement. By using the Mecanum wheel 122, the material to be rejected on the conveying assembly 1 can be conveyed in a different direction. The working principle of the Mecanum wheel 122 is existing technology and will not be described in detail here.

[0049] Optionally, multiple wheat straw conveyor units 12 are provided, and the rotation shafts 121 of the multiple wheat straw conveyor units 12 are spaced apart along the first direction. Multiple wheat straw conveyor units 12 can ensure the stability of the material to be rejected during conveying. The specific number of wheat straw conveyor units 12 can be set according to the conveying length, and the distance between two adjacent wheat straw conveyor units 12 is based on ensuring the smooth conveying of the material to be rejected, and is not limited here.

[0050] Specifically, continue to refer to Figure 1 The conveying assembly 1 also includes a roller conveyor 13, which is positioned upstream of the wheel conveyor 12 in a first direction. The rotating shaft of the roller conveyor 13 is parallel to the rotating shaft 121 of the wheel conveyor 12. Material to be rejected can be conveyed to the wheel conveyor 12 via the roller conveyor 13. The friction between the roller conveyor 13 and the material to be rejected is lower, enabling rapid transfer of the material.

[0051] Correspondingly, multiple roller conveyors 13 are also provided, and the rotating shafts of the multiple roller conveyors 13 are spaced apart along the first direction.

[0052] More specifically, the reversing device also includes a multi-ribbed belt drive assembly (not shown). The wheel conveyor 12 and the roller conveyor 13 are connected by the multi-ribbed belt drive assembly. The multi-ribbed belt drive has a large power transmission capacity, low vibration, and smooth operation.

[0053] More specifically, the reversing device further includes a drive assembly 5, the output end of which is connected to the wheel conveyor 12 and the roller conveyor 13 via a multi-wedge belt drive assembly. Both the wheel conveyor 12 and the roller conveyor 13 have wedge belt connecting portions 123 at their ends for connection to the output end of the drive assembly 5 via the multi-wedge belt drive assembly. Exemplarily, the drive assembly 5 may be a motor as used in the prior art.

[0054] Continue to refer to Figure 1 The reversing device also includes a support frame 4, which comprises a first support plate 41 and a second support plate 42. The first support plate 41 and the second support plate 42 are spaced apart perpendicular to the first direction and are respectively connected to both sides of the conveying assembly 1. The two ends of the guardrail portion 21 are respectively connected to the first support plate 41 and the second support plate 42. The two ends of the wheel conveyor 12 are rotatably connected to the first support plate 41 and the second support plate 42, and the two ends of the roller conveyor 13 are rotatably connected to the first support plate 41 and the second support plate 42. By setting the first support plate 41 and the second support plate 42, reliable support can be provided for the wheel conveyor 12 and the roller conveyor 13, ensuring the stable operation of the conveying assembly 1.

[0055] Furthermore, baffles may be provided on the first support plate 41 and / or the second support plate 42 to prevent the material to be rejected on the conveying assembly 1 from shifting left and right and falling off during the conveying process.

[0056] Continuing, as Figure 1 and Figure 3 As shown, the rotating part 22 includes a plurality of rollers 221 arranged along a second direction, and the rotation axis of the rollers 221 is perpendicular to both the first and second directions. In this embodiment, the rotating part 22 includes two rows of rollers 221 arranged vertically, with each row including a plurality of rollers 221 arranged along the second direction. With this arrangement, when the side of the material to be rejected comes into contact with the roller 221, the roller 221 rotates, thereby effectively reducing friction between the roller 221 and the side of the material to be rejected, reducing wear, and ensuring the integrity of the product's appearance.

[0057] Furthermore, continue to refer to Figure 1 The material detection element 3 is located on the side of the guardrail 21 near the feeding end. The material detection element 3 is configured to detect the feeding information of the material to be rejected at the feeding end. The reversing device also includes a control module (not shown). The control module is communicatively connected to both the conveying assembly 1 and the material detection element 3. The control module can control the start and stop of the conveying assembly 1 based on the feeding information received from the material detection element 3. For example, the material detection element 3 can be a photoelectric sensor, and the control module can be a PLC, etc. Their control principles and connection relationships are existing technologies and will not be elaborated here.

[0058] In other words, the material detection component 3 can detect whether there are materials to be rejected at the feeding end. Only after the materials to be rejected at the feeding end are successfully fed will the conveying component 1 continue to convey new materials to be rejected, thereby ensuring that there is no material accumulation at the feeding end, avoiding jamming, and realizing continuous feeding one by one.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
