[0045] Preferably, please see Figures 1 to 7 This embodiment proposes a powered SPS flexible conveyor line. The flexible pallet feeding system 40 includes a belt conveyor 41 located inside the conveyor frame 21, and the belt conveyor 41 adopts a segmented structure.

[0047] like Figures 1 to 7 As shown in the figure, the working principle of the power SPS flexible conveyor line provided in this embodiment is as follows:

[0048] The power line mainly consists of: an integrated feeding system 10, an upper-level batching system 20, a feeding system 30, a flexible pallet feeding system 40, and a flexible control cabinet 50.

[0049] I. Integrated Feeding System

[0050] like Figure 2As shown, the integrated feeding system 10 mainly consists of a feeding frame 11, flexible shelving pallets 12, and a first servo drive system 13. The feeding frame 11 is welded from multiple square tubes. The feeding frame 11 is 1.2 meters long, 2 meters high, and 1.3 meters wide. After stress analysis, it fully meets the design requirements in terms of strength and rigidity, and the design is reasonable, economical, and aesthetically pleasing.

[0051] like Figure 2 As shown, the first servo drive system 13 consists of a servo motor 131, a grating 132, a limit switch 133, a chain drive mechanism 134, and a motion bracket 135. When the lower flexible shelf pallet 12 arrives, the operator pushes the flexible shelf pallet 12 onto the motion bracket 135 and then presses the up button. Both the servo motor 131 and the motion bracket 135 are equipped with gears and connected by a chain. The servo motor 131 drives the chain to make the motion bracket 135 move upward within the guide rail. When the motion bracket 135, together with the flexible shelf pallet 12, rises to a suitable distance, the motion bracket 135 will touch the limit switch 133, and the servo motor 131 will brake and stop working. The operator then pushes the flexible shelf pallet 12 out of the motion bracket 135 and sends it to the conveyor rail of the upper batching system 20. Then the operator presses the down button, and the motion bracket 135 returns to its original position. The grating 132 surrounds the entire drive system. The first servo drive system 13 is interlocked with the grating 132 during movement. The operator presses the up and down buttons outside the light rays of the grating 132, so as not to affect the operation of the servo drive system. When a person crosses the light rays of the grating, the first servo drive system 13 immediately stops working to ensure the safety of the person.

[0052] The flexible racking pallet 12 primarily functions to hold powered SPS (Special Purpose Equipment). It mainly consists of a pallet body 121, a fixing frame 122, and second rollers 1353. The pallet body 121 is primarily made of square tubing with numerous holes perpendicular to the conveyor line. The fixing frame 122, mounted on top of this, allows for spacing adjustment by fitting different holes. The fixing frame 122 uses a first square tubing fitted over a second square tubing, allowing the first square tubing to move within the second, providing telescopic functionality to adjust its size and secure tooling according to different powered SPS. This ensures that the powered SPS is not damaged or poses a hazard to personnel during transport. The second rollers 1353 primarily enable the entire flexible racking pallet 12 to roll within the guide rails on the upper level of the conveyor line.

[0053] II. Upper-level ingredient batching system

[0054] The upper-level material feeding system 20 mainly consists of a conveyor frame 21 and conveyor rails 22. The conveyor frame 21 is primarily welded from square tubing. The conveyor frame 21 is 60 meters long and 1 meter wide. Stress analysis shows that the strength and rigidity of the conveyor line meet the requirements, and spare interfaces are provided for easy future production line upgrades. The conveyor rails are made of 2mm thick steel plates bent into L-shapes and welded to the conveyor frame. Dense intermittent welding ensures a strong connection, allowing multiple flexible pallet racks 12 to operate under high pressure for extended periods. The conveyor frame 21 is equipped with multiple emergency stop switches to ensure timely shutdown of the conveyor line in case of emergencies.

[0055] III. Feeding System

[0056] Similar to the integrated material handling system 10, it mainly consists of a unloading frame 31, flexible rack pallets, and a second servo drive system 32. The unloading frame 31 is welded from multiple square tubes, measuring 1.2 meters long, 2 meters high, and 1.3 meters wide. Stress analysis confirms that its strength and rigidity fully meet design requirements, and its design is reasonable, economical, and aesthetically pleasing. The second servo drive system 32 consists of a servo motor, a light grating, and limit switches. Its main function is to drive the flexible rack pallets down to the subsequent flexible pallet retrieval system for collection. It is also interlocked with the light grating; when personnel are unloading or retrieving materials in the pallet area, the second servo drive system 32 will not be activated to ensure personnel safety.

[0057] IV. Flexible Pallet Feeding System

[0058] The flexible pallet feeding system 40 shares the conveyor frame 21 of the upper batching system 20, but adds a belt conveyor line 41 inside the frame. The belt conveyor line 41 is arranged in short distances and multiple segments. This shares the conveyor frame 21 and the lower space, while also helping to save costs and ensure work efficiency.

[0059] V. Flexible Control Cabinet

[0060] The flexible control cabinet 50 is equipped with a human-machine interface 51. Manual control is achieved by sending control signals to the PLC via manual buttons, which drive the servo drive system. Simultaneously, sensors can also transmit signals to the PLC for automatic control. Speed ​​adjustment can be achieved by adjusting the servo motor speed through the human-machine interface 51. This gives the flexible control cabinet 50 functions such as speed control, automatic, manual, and emergency stop. The grating signal can be transmitted to the PLC and linked to a three-color indicator light. In case of an anomaly, it provides both emergency stop and hazard alarm functions. RS485 and RS432 communication protocol interfaces are provided for future upgrades to intelligent systems and the Internet of Things (IoT).
