[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-5This utility model provides a technical solution: a multi-line parallel transport and conveying device, including a main conveyor belt 1 and multiple sub-conveyor belts 2 arranged side by side at the conveying end position of the main conveyor belt 1, i.e. Figure 1 The distribution shown is of common knowledge and therefore will not be described in detail. To address the problem that existing technologies rarely address and lack efficient and reliable solutions for sorting main conveyor belts and branch conveyor belts distributed in the same direction and parallel, this application provides the following embodiments:

[0029] Example 1

[0030] This embodiment aims to provide a distribution guide mechanism 3 that is assembled on the main conveyor belt 1 and distributed close to the belt surface of the main conveyor belt 1. The distribution guide mechanism 3 is divided into the following according to its structure:

[0031] The guide channel is composed of symmetrically distributed arc-shaped guide plates 31. The two ends of the guide channel are divided into a narrow opening and a wide opening according to the diameter. The wide opening faces the conveying direction of the main conveyor belt 1 and the diameter is consistent with the width of the main conveyor belt 1.

[0032] The guide channel 32 is driven to swing around the first end near the narrow opening of the guide channel, and the second end is connected to the inlet of any sub-drive belt 2.

[0033] Specifically, the aforementioned guiding mechanism 3 is made of stainless steel or plastic.

[0034] Furthermore, the aforementioned main conveyor belt 1 includes a frame, and the arc-shaped guide plates 31 are located at the wide end and distributed on the side walls of adjacent frames. The narrow openings are coaxially distributed along the central axis of the main conveyor belt 1. The purpose of the guide channel is to gather the scattered items to be sorted, so that the items to be sorted are conveyed one by one through the narrow opening. Then, they enter the guide channel 32 and are guided into the corresponding sub-conveyor belt 2 for further conveying.

[0035] Furthermore, a second gantry bracket 51, which is fixedly installed on the frame of the main conveyor belt 1 by bolts, is fixedly installed on the second gantry bracket 51 by bolts, and the output end of the drive motor 5 can be directly connected to the guide channel 32, thereby driving the guide channel 32 to swing.

[0036] In the above technology, the items to be sorted on the main conveyor belt 1 enter through the wide opening of the guide channel, and then exit one by one from the narrow opening as they are conveyed. They then enter the guide channel 32, where a drive causes it to swing, guiding the items into the corresponding sub-conveyor belt 2 for further conveying. This design is simple in structure, convenient and quick to operate, and meets the sorting requirements of parallel main and branch conveyor belts in the same direction.

[0037] Example 2

[0038] Based on Embodiment 1, this embodiment aims to provide a labor-saving structure for the movement of the guide channel 32. Combined with... Figure 2 and Figure 3 As shown, the guide channel 32 consists of symmetrically distributed vertical plates 321, with short beams 322 fixedly mounted on the top of each of the two vertical plates 321 by screws. The short beams 322 are distributed near the sub-drive belt 2, and a connecting rod 52 is fixedly mounted on the output end of the drive motor 5. The waist groove on the connecting rod 52 is in sliding engagement with the bolts fixed on the short beams 322. When the drive motor 5 starts, the connecting rod 52 begins to move (rotate or translate). In the initial stage, the waist groove can slide relative to the bolt (or pin), at which time only a small sliding friction force and the inertia of the connecting rod itself need to be overcome. This significantly reduces the load that needs to be overcome at the moment of motor start-up (mainly the static friction and inertia of the entire guide channel 32 and the items it may carry). This sliding engagement design also allows for small assembly errors, thermal expansion, or changes in drive belt tension in the system, avoiding rigid impacts and excessive stress. Only when the movement of the connecting rod 52 causes one end of the waist groove to contact the bolt (or pin) does it begin to effectively push or pull the short beams 322, thereby causing the entire guide channel 32 to swing. This transition from free sliding to rigid actuation is smoother than a direct rigid connection, effectively reducing impact and improving system stability and motor lifespan.

[0039] Furthermore, in combination Figure 3 As shown, vertically distributed guide rollers 6 are rotatably mounted at the end of the vertical plate 321 near the guide channel (narrow opening of the arc-shaped guide plate 31). The purpose of the guide rollers 6 is that when the guide channel 32 deflects to align with a sub-conveyor belt 2, the items exiting the narrow opening of the guide channel first come into contact with the surface of the rotating guide rollers 6, allowing them to smoothly roll into the guide channel 32. This effectively avoids the items directly contacting the fixed end of the vertical plate 321, preventing jamming or abnormal conveying, and improves the smoothness of the entry.

[0040] Example 3

[0041] Based on Example 1, combined with Figure 3 As shown, this embodiment aims to provide a vision system, the core of which is a camera 4, which is fixedly mounted on the frame of the main conveyor belt 1 via a first gantry bracket 41. The acquisition surface (lens) of the camera 4 faces the surface of the main conveyor belt 1, preferably located in the center area or above the narrow opening of the guide channel (arc guide plate 31), so as to clearly capture images when items are gathered and sorted through the guide channel.

[0042] Camera 4 is used to capture image information (such as shape, color, barcode, QR code, etc.) of items passing beneath it, thereby identifying and determining the type of the item and its target sub-conveyor belt 2 to be sorted. The identification result is transmitted to the control system. Based on the target sub-conveyor belt information, the control system calculates the required deflection angle and controls the drive motor 5 to rotate to the predetermined angle, thereby driving the guide channel 32 to swing, aligning its exit with the entrance of the target sub-conveyor belt 2, and guiding the items entering into the corresponding sub-conveyor belt 2.

[0043] It should be noted that the visual processing algorithm and control system for identifying and classifying items based on camera images and generating corresponding control commands (drive motor angles) are well-known technologies that can be implemented by those skilled in the art based on specific application scenarios (such as sorting item types and identification methods), and therefore will not be described in detail.

[0044] Example 4

[0045] Based on Example 1, combined with Figure 4 and Figure 5 As shown, in this embodiment, the third gantry bracket 7 is fixedly installed on the frame, and then equidistantly distributed rotating shafts 71 are fixedly installed on the side facing the sub-drive belt 2. The axis of the rotating shaft 71 is on the same plane as the edge of the sub-drive belt 2. That is, there is one sub-drive belt 2 between two adjacent rotating shafts 71, and on both sides, there is one rotating shaft 71 corresponding to one sub-drive belt 2 on the inner wall of one side of the frame.

[0046] Furthermore, a groove 81 is formed on the guide plate 8, and the rotating shaft 71 is rotatably disposed within the groove 81 and centrally located. An elastic metal plate 9 is then fixedly mounted on the rotating shaft 71, with its two ends respectively fixed to the inner walls of opposite sides of the groove 81. The aforementioned elastic metal plate 9 provides a restoring force to return the guide plate 8 to a vertical state. When the guide plate 8 is deflected by an external force, the elastic metal plate 9 undergoes elastic deformation to store energy; after the external force is removed, the elastic force drives the guide plate 8 back to its upright position. Figure 1 The state shown.

[0047] As items are conveyed on the main conveyor belt, passing under camera 4, camera 4 captures images of the items or identifies their tags to determine the type of item and its target sub-conveyor belt 2 to be sorted. Based on the target sub-conveyor belt information, the control system controls the drive motor 5 to rotate to a predetermined angle. The drive motor 5, through the sliding cooperation of connecting rod 52 and waist groove bolts, drives the guide channel 32 to move as a whole, precisely aligning the outlet ends of its two vertical plates 321 with the inlet ends of the two guide plates 8 on both sides of the target sub-conveyor belt 2. The control system energizes the electromagnets 82 mounted on the top of the guide plates 8 on both sides of the target sub-conveyor belt 2. Simultaneously, the control system activates the neodymium magnets 323 mounted at the ends of the vertical plates 321 on both sides of the guide channel 32. The energized electromagnets 82 generate a strong magnetic field, creating a strong magnetic attraction with the corresponding neodymium magnets 323 at the ends of the vertical plates 321. This attraction overcomes the restoring force of the elastic metal plate 9, pulling the upper end of the guide plate 8 towards the lower end of the vertical plate 321. Since the vertical plate 321 has been adjusted to a specific tilt angle by the drive motor 5, the guide plate 8 is forced to rotate around its pivot 71 under the action of magnetic attraction until its tilt angle is completely consistent with that of the vertical plate 321. At this time, the outlet of the guide channel 32 and the inlet of the guide plate 8 are smoothly connected, forming a continuous guide path. The item enters the guide channel 32 from the main drive belt, slides down along the tilted vertical plate 321, and seamlessly transitions to the guide plate 8 with the same tilt angle, and is finally guided to fall into the target sub-drive belt 2.

[0048] Reset: After the item passes through, the control system disconnects the power supply to the electromagnet 82, and the magnetic field disappears. The elastic potential energy stored in the elastic metal plate 9 is released, driving the guide plate 8 to quickly and stably spring back to the vertical position, preparing for the next sorting. The vertical plate 321 is also driven by the drive motor 5 to reset or prepare to move to the next target position.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
