[0002] In recent years, as my country's sheet metal processing industry has accelerated its transformation towards intelligent manufacturing, material storage and transportation systems centered on automated storage and retrieval systems (AS / RS) have become a key direction for production line upgrades. The mainstream solution utilizes a multi-column sheet metal warehouse system composed of telescopic forklifts and roll forming racks, coupled with a single-layer in / out conveyor line, to initially achieve automated raw material supply for laser processing equipment. However, when dealing with the trend of multi-variety, small-batch production, traditional single-layer in / out conveyor lines have revealed significant shortcomings: their single-channel linear operation mode limits the transport cycle time, making it difficult to meet the concurrent material supply needs of multiple laser processing machines; simultaneously, a single conveyor layer cannot accommodate the parallel scheduling of sheet metal of different materials / specifications, and frequent production line changes further reduce the overall system efficiency.

[0003] Therefore, the industry urgently needs to break through the traditional planar conveying architecture and develop a new type of conveying system with multi-channel parallel operation capabilities. To this end, we propose a multi-layer discharge conveyor line device adapted to multi-column sheet metal cutting warehouses. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a multi-layer material conveying line device adapted to a multi-column sheet metal cutting library, including a lower conveying line unit and an upper conveying line unit. The lower conveying line unit includes a lower conveying line frame 1, a lower conveying chain 6 and a lower conveying line drive motor 7. The lower conveying chain 6 is disposed on the lower conveying line frame 1 and driven by the lower conveying line drive motor 7. A sheet metal material tray 2 carrying sheet metal raw materials 3 is placed on the lower conveying chain 6.

[0023] The lower conveyor frame 1 serves as a base frame, fixed to the foundation, and is used to support the lower conveyor chain 6 and related components. The lower conveyor drive motor 7 drives the lower conveyor chain 6 to reciprocate, thereby moving the sheet metal material tray 2 back and forth to realize the conveying of the sheet metal material 3. The sheet metal material tray 2 is used to store the sheet metal material to be processed and is directly connected to the subsequent laser cutting process.

[0024] The upper conveyor unit includes an upper conveyor frame 11, an upper conveyor chain 13, and an upper conveyor drive motor 14. The upper conveyor chain 13 is disposed on the upper conveyor frame 11 and driven by the upper conveyor drive motor 14. An upper conveyor pallet transfer frame 12 for placing the sheet metal raw material pallet 2 is fixed on the upper conveyor chain 13.

[0025] The upper conveyor frame 11 is set parallel to the lower frame to form an independent conveying level; the upper conveyor drive motor 14 drives the upper conveyor chain 13, which in turn drives the upper conveyor pallet transfer frame 12 to move, realizing the upper transport of sheet metal raw material pallets 2, and forming a double-layer parallel conveying network with the lower conveyor unit.

[0026] The lower conveyor frame 1 is equipped with a pallet limiting guide plate 4, a pallet pneumatic locking mechanism 5, a lower pallet arrival detection component, and a lower pallet arrival mechanical limit 10. The upper conveyor frame 11 is equipped with an upper pallet arrival detection component and an upper pallet arrival mechanical limit 17.

[0027] The pallet limiting guide plate 4 restricts the left and right position of the sheet metal raw material pallet 2 and guides its forward and backward movement to ensure accurate conveying path; the pallet pneumatic locking mechanism 5 locks the pallet at the discharge position to prevent pallet displacement during subsequent material handling, which could lead to abnormal material handling; the position detection component (including deceleration switch and position switch) realizes automatic detection and control of the pallet position, and the mechanical limit 10 / 17 prevents the pallet from sliding off the conveyor line.

[0028] Specifically, the lower conveyor frame 1 is fixed to the foundation; the sheet metal raw material pallet 2 is placed on the lower conveyor chain 6; the sheet metal raw material 3 is placed on the sheet metal raw material pallet 2; the pallet limiting guide plate 4 is installed on both sides of the lower conveyor frame 1; there are two pallet pneumatic locking mechanisms 5, which are installed on the lower conveyor frame 1. There are three lower conveyor chains 6, which are installed on the chain fixing frame of the lower conveyor frame 1; the lower conveyor drive motor 7 is installed in the middle of the lower conveyor frame 1; there are two lower pallet pre-positioning deceleration switches 8, installed on the sides of the lower conveyor frame 1, at both ends; there are two lower pallet position switches 9, installed on the sides of the lower conveyor frame 1, at both ends; the lower pallet position mechanical limit 10 is installed on the lower conveyor frame 1, located at both ends of the lower conveyor chain 6; the upper conveyor frame 11 is fixed to the foundation; the upper conveyor pallet transfer frame 12 is fixed to the upper conveyor chain 13; the upper conveyor... There are two conveyor chains 13, which are installed on the chain fixing frame of the upper conveyor frame 11; the upper conveyor drive motor 14 is installed in the middle of the upper conveyor frame 11; there are two deceleration switches 15 before the upper pallet arrives, which are installed on the side of the upper conveyor frame 11 at both ends; there are two upper pallet arrival switches 16, which are installed on the side of the upper conveyor frame 11 at both ends; the upper pallet arrival mechanical limit switch 17 is installed on the upper conveyor frame 11, located at both ends of the upper conveyor chain 13; the electrical control system 18 is installed on the lower conveyor frame 1; the pneumatic unit 19 is installed on the lower conveyor frame 1.

[0029] In the above scheme, the pallet limiting guide plate 4 is set on both sides of the lower conveyor frame 1. The pallet limiting guide plate 4 set on both sides forms a guide channel, and the physical limiting ensures that the sheet metal raw material pallet 2 maintains straight movement during the conveying process, avoiding deviation that would affect subsequent material picking operations.

[0030] In the above scheme, the pneumatic locking mechanism 5 of the pallet is set at the discharge position of the lower conveyor frame 1. The pneumatic locking mechanism 5 of the pallet at the discharge position locks the sheet metal raw material pallet 2 through pneumatic control. When the pallet reaches the material picking station of the laser machine loading and unloading equipment, the locking mechanism is activated to ensure the positioning accuracy of the pallet and ensure the stability and safety of the material picking action.

[0031] In the above scheme, the lower pallet arrival detection component includes a lower pallet pre-arrival deceleration switch 8 and a lower pallet arrival switch 9 located at both ends of the side of the lower conveyor frame 1. The upper pallet arrival detection component includes an upper pallet pre-arrival deceleration switch 15 and an upper pallet arrival switch 16 located at both ends of the side of the upper conveyor frame 11. The pre-arrival deceleration switch triggers the motor to slow down when the pallet approaches the target position, achieving buffer deceleration. The arrival switches are used to accurately detect whether the pallet has reached the designated position, and cooperate with the electrical control system 18 to complete the start and stop control of the conveyor line, ensuring positioning accuracy.

[0032] In the above scheme, three lower conveyor chains 6 and two upper conveyor chains 13 are provided, which respectively drive the sheet metal raw material pallet 2 and the upper conveyor line pallet transfer frame 12 to move back and forth. The three lower conveyor chains 6 provide stable pallet load-bearing capacity to adapt to the weight and size of the sheet metal raw material 3; the two upper conveyor chains 13 drive the pallet transfer frame 12 to achieve efficient transfer of the upper pallet, and the difference in the number of chains between the upper and lower layers matches their respective load requirements.

[0033] The above scheme also includes an electrical control system 18 and a pneumatic unit 19. The electrical control system 18 is installed on the lower conveyor frame 1, and the pneumatic unit 19 is installed on the lower conveyor frame 1. The electrical control system 18 integrates electrical control components (such as contactors and frequency converters) to realize power control, status monitoring, and communication with the main system of the upper and lower conveyor lines; the pneumatic unit 19 filters and adjusts the compressed air pressure to provide a stable air source for the pallet pneumatic locking mechanism 5, ensuring the reliability of the locking action.

[0034] In the above scheme, the lower conveyor frame 1 and the upper conveyor frame 11 are modular structures. The modular structure design supports vertical stacking of conveyor layers, which can be expanded into a multi-layer conveyor system according to customer needs, compatible with different feeding scales and material return requirements, and improving equipment flexibility and scalability.

[0035] Working principle:

[0036] This multi-layer feeding conveyor device, which is adapted to sheet metal cutting multi-row library, allows the stacker crane to extract the corresponding sheet metal raw material pallet 2 (carrying sheet metal raw material 3) from the multi-row library according to the scheduling signal of the electronic control system 18 when the laser cutting machine issues a feeding instruction, and place it on the lower conveyor chain 6 or the upper conveyor pallet transfer frame 12.

[0037] Lower layer conveyor: The lower layer conveyor line drive motor 7 starts, driving the three lower layer conveyor chains 6 to move. The sheet metal raw material pallet 2 moves along the pallet limit guide plate 4 towards the material picking station. When the bottom of the pallet triggers the lower layer pallet arrival deceleration switch 8, the motor slows down; when it continues to move until the lower layer pallet arrival switch 9 is triggered, the pallet pneumatic locking mechanism 5 starts, locking the pallet position. At the same time, the lower layer pallet arrival mechanical limit 10 prevents the pallet from sliding out.

[0038] Upper-level conveying: The upper-level conveyor line drive motor 14 works synchronously or independently, and drives the pallet transfer frame 12 to move through two upper-level conveyor chains 13. The upper-level pallet is positioned by the deceleration switch 15 and the positioning switch 16 before the upper-level pallet arrives, thus realizing the independent conveying of the upper-level pallet.

[0039] When the lower conveyor line is performing material handling operations, the electrical control system 18 monitors the status of the upper and lower layers in real time, automatically pausing the operation of the upper conveyor line or reducing its speed. Through timing control, it avoids the lower layer's operating window, preventing mechanical interference between the upper and lower layers. After material handling is completed, the pneumatic locking mechanism 5 of the lower pallet is released, and the pallet returns to the automated storage and retrieval system with the chain. The upper conveyor line continues to perform subsequent conveying tasks according to instructions, forming a dynamic, collaborative material supply process with two cascaded layers.

[0040] Straight-through conveying mode: Raw materials are directly conveyed to the laser equipment via the lower or upper conveyor line, which is suitable for continuous production scenarios; the modular structure allows for vertical stacking of conveyor layers to meet the personalized needs of different customers for material supply scale and material return to the warehouse.

[0041] The above working principle, through layered independent control, precise positioning detection and intelligent collaboration, achieves efficient connection between multiple columns of the library and subsequent processes, significantly improving the overall efficiency of the automated sheet metal processing production line.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
