[0002] Currently, pallets used in the industrialized production of edible fungi are typically handled and transferred using forklifts. However, many edible fungi companies, in order to improve work efficiency, often equip pallets with automated transport lines for conveying and transferring them, a symbol of modern industry moving towards intelligent manufacturing. The automated transport lines for pallet conveying and transfer require a new type of mechanism for pallet turning: the automatic pallet reversing mechanism.

For pallet conveying and transfer, eliminating forklift handling and manual operation reduces production costs and meets the diverse needs of today's customers. With the rapid development of the edible fungi industry both domestically and internationally, the automatic pallet reversing mechanism required for large-scale pallet conveying and transfer will have a broad application scope.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Reference Figure 1-6 An automatic pallet reversing mechanism includes a frame 1, on which a longitudinally arranged conveying mechanism B4 is installed. On the frame 1 on both sides of the longitudinal direction of the conveying mechanism B4, a transversely arranged conveying mechanism A3 is installed. The conveying mechanism A3 and the conveying mechanism B4 are arranged perpendicularly at 90°. The conveying mechanism A3 is used to receive the transversely input pallet 2, and the conveying mechanism B4 is used to output the pallet 2 longitudinally to realize the reversing operation of the pallet 2.

[0015] To enable the pallet 2 to switch between conveying mechanism A3 and conveying mechanism B4, conveying mechanism A3 is mounted on frame 1 via a lifting power device 6. This allows the lifting power device 6 to raise the height of conveying mechanism A3 to receive pallet 2, and then lower the height of conveying mechanism A3 to place pallet 2 onto conveying mechanism B4. Preferably, the lifting power device 6 is a cylinder or hydraulic cylinder, which is vertically fixed on frame 1. A lifting frame is installed at the drive end of the cylinder or hydraulic cylinder, and conveying mechanism A3 is mounted on the lifting frame.

[0016] To ensure the stability of the lifting process, guide blocks are installed on the lifting frame, and guide grooves are provided on the frame 1 to cooperate with the guide blocks. When the cylinder or hydraulic cylinder works, it drives the lifting frame to make vertical lifting and lowering movements along the guide groove, thereby driving the conveying mechanism A3 to realize the function of vertically lifting the pallet 2.

[0017] A transition roller 5 is installed on one side of the frame 1 for cooperating with the conveying mechanism A3. The transition roller 5 serves as a transition device between the conveying mechanism A3 and other equipment to facilitate the transport of the pallet 2. When the pallet 2 enters this mechanism from the external pallet 2 conveying line, it first passes through the transition roller 5 and then enters the conveying mechanism A3, thus playing a role in smooth transition. Preferably, there are two transition rollers 5, which are arranged side by side in the horizontal direction on one side of the frame 1.

[0018] In order to better transfer the pallet 2 from the transition roller 5 to the conveying mechanism A3, one side of the transition roller 5 is arranged to overlap with the conveying mechanism A3 in the lateral direction, and the other side of the transition roller 5 is set as the input side of the pallet 2 for cooperation with the external pallet 2 conveying line.

[0019] A position sensor for detecting the position of pallet 2 is also installed on the frame 1. The position sensor is connected to the input terminal of an external PLC controller, and the conveying mechanism A3, conveying mechanism B4, and lifting power device 6 are all connected to the output terminal of the external PLC controller. When pallet 2 enters this mechanism, the position sensor detects the position information of pallet 2 and transmits the information to the PLC controller. The PLC controller coordinates and controls the actions of conveying mechanism A3, conveying mechanism B4, and lifting power device 6 according to the preset program and the received position information to realize the automatic reversing conveying of pallet 2. The PLC controller program involved is a conventional technique in this field and can be written by those skilled in the art using existing PLC programs.

[0020] In actual use, the conveying mechanism A3 is a chain conveyor or a belt conveyor, and the conveying mechanism B4 is a chain conveyor or a belt conveyor. The chain conveyor drives the pallet 2 through chain transmission, which is suitable for heavy-duty or large-size pallets 2. It has the advantages of wear resistance and long service life, and is often used in industries such as edible fungi, pharmaceuticals, chemicals, auto parts, and building materials. The belt conveyor uses belt conveying, which is suitable for conveying and transferring small pallets 2, small boxed and bagged items. It runs smoothly and has low noise. It is mainly used for sorting express parcels and transferring light goods in the food industry. The appropriate type can be selected according to actual needs to realize the movement of pallets 2.

[0021] The working process of the automatic reversing mechanism for pallets provided in this application is as follows: 1. The external pallet 2 conveyor line delivers the pallet 2 to the transition roller 5, and the pallet 2 is conveyed to the inlet of the automatic reversing mechanism of the pallet 2 through the transition roller 5; 2. At this time, the position sensor detects the position of the pallet 2 and transmits the signal to the PLC controller. After receiving the position signal, the PLC controller controls the lifting power device 6 to work, drives the lifting frame to rise, and the conveying mechanism A3 rises accordingly, lifting the pallet 2 to the target height, aligning it with the transition roller 5, so that the pallet 2 enters the conveying mechanism A3. 3. When the pallet 2 reaches the designated position on the conveying mechanism A3, the lifting power device 6 descends, and the pallet 2 is lowered onto the conveying mechanism B4 via the conveying mechanism A3. 4. The PLC controller controls the start of the conveyor mechanism B4, which smoothly delivers pallet 2 to the target conveyor line, completing the horizontal transfer of pallet 2; 5. After the turn of pallet 2 is completed, the lifting power unit 6 drives the lifting frame to the initial position, and the conveying mechanism A3 also returns to the initial state, waiting for the arrival of the next pallet 2, ready to carry out the next reversal task.

[0022] The advantages of the automatic reversing mechanism for pallets provided in this application are: 1. Multi-directional conveying: Supports vertical and horizontal multi-dimensional transportation, which can flexibly adapt to complex production layouts and meet the pallet conveying needs in different scenarios; 2. Precise positioning: Positioning is achieved through photoelectric / encoder (position sensor), and the pallet positioning error can be controlled within ±1mm, ensuring the accuracy and stability of the pallet during the reversal process; 3. High-efficiency sorting: The single machine can process 600-1200 pieces / hour, which greatly improves the conveying efficiency of the pallet and meets the needs of large-scale production; 4. Space optimization: Reduces manual handling paths, improves space utilization, makes the production site cleaner and more orderly, and reduces production costs; 5. Seamless integration: It can work in conjunction with conveyor lines, RGVs (rail-guided vehicles), AGVs (automated guided vehicles), sorting machines, elevators and other equipment to achieve automation and intelligence of the entire logistics system.
