[0091] The magnetic separation mechanism is connected to the magnetic separation mechanism through a conveying line 64; the magnetic separation mechanism is an eddy current separator 69.

[0092] On the conveying line 64, an air separator 65 is also arranged between the magnetic separation mechanisms.

[0093] In this embodiment, weighing platform equipment is set at the loading station, unloading station and docking station. The weighing range of the weighing platform equipment is 0-1.5T and the accuracy is 1 / 1000. The weighing platform adopts 4-corner weighing, and weighing modules are distributed at the four corners. Limits are set on the weighing plane to prevent accidents. After the assembly is completed, the display first removes the weight of the weighing plane (peeling). When the AGV car receives the signal, it starts to fork the goods to the weighing platform position and places it on the weighing platform. At the same time, the AGV car sends a signal to the host computer, and the display (LED light) sends a signal to the host computer through the network cable (supporting HTTP protocol). The host computer records the weight. At the same time, the host computer sends a signal to the camera (supporting HTTP protocol) to take pictures for storage (no need to take pictures for storage in the unloading area). After completion, the host computer sends a signal to the AGV car, and the AGV car forks the goods away; the weighing process is completed.

[0094] The receiving device is fixed on the line body through the lower baffle plate and the upper opening. The upper computer monitors the weight on the weighing platform all the time. When the weight of the ton bag reaches the specified weight, the upper computer sends a signal to the AGV trolley and sends a signal to the PLC at the same time. The PLC controls the solenoid valve and the cylinder performs the pushing action. At this time, the entire receiving device will be completely closed. At this time, the material on the conveyor line will enter the receiving device. When the AGV trolley delivers the new ton bag to the specified position, it sends a signal to the upper computer, and the upper computer sends a signal to the PLC. The PLC controls the solenoid valve and the cylinder opens. The material stored in the middle enters the ton bag through the gap. During this period, the cylinder is always in a contracted state until the weight of the weighing platform reaches the specified weight again; this cycle is repeated.

[0095] Automatic weighing equipment is installed at the loading station, receiving station and docking station. The equipment weighing range is 1-1.5t and the accuracy is 1 / 1000. The weighing equipment has a data acquisition function, which can automatically record the weighing data, automatically connect to the upper system, and can be linked with the camera system.

[0096] In one or more embodiments, in the automatic logistics link, when loading materials, the system issues an order, the AGV receives the loading task, and sends the cut cables in the temporary storage area to the weighing area for automatic weighing, and the weighing data is automatically recorded and uploaded; after weighing, the cables are sent to the loader; when unloading materials, each receiving ton bag is equipped with an automatic weighing device. After reaching the set weight, the system automatically calls the AGV for transfer. During the transfer process, the receiving port buffer device is automatically closed for receiving material buffering, and reopened after the empty ton bag is in place.

[0097] In one or more embodiments, the waste cable disassembly and recycling system further includes: a logistics transfer device, which is used to perform logistics transfer on the packaged and sorted steel armor.

[0098] Specifically, Figure 3 and Fig.14 As shown, the logistics transfer device includes: a shelf 211, a weighing device 212 and an AGV vehicle 213;

[0099] First, the AGV forklift 61 places the cables and tooling 68 in the pre-processing area on the front weighing platform 66 for weighing. After weighing, the AGV forklift 61 transports the cables and tooling (68) in the pre-processing area to the front end of the grabbing and translation assembly 64 according to a predetermined route, and then transports the cables 62 to be processed to the production line through the cable conveyor 66 for further processing.

[0100] After processing, the AGV forklift 61 transports the filled ton bag 68 and plastic pallet 69 to the beam rack 70.

[0101] According to the business needs of the yard, the main body of the automatic logistics of the cable disassembly line adopts the form of a forklift AGV, which uses the fork to pick up special tooling fixtures and tooling to complete automatic logistics, greatly improving the operating efficiency and stack circulation efficiency.

[0102] like Fig.14 As shown, the cross-beam shelf 70 is mainly composed of guide rails 71, columns 72, cross beams 73, diagonal beams 74 and some fasteners. The AGV forklift transports the ton bags 68 and plastic pallets 69 filled with materials to the cross-beam shelf.

[0103] According to the business needs of the yard, the main body of the automatic logistics of the cable disassembly line adopts the form of a forklift AGV, which uses the fork to pick up special tooling fixtures and tooling to complete automatic logistics, greatly improving the operating efficiency and stack circulation efficiency.

[0104] In one or more embodiments, a recycling method based on the waste cable disassembly and recycling system as described above is also provided, comprising:

[0105] The automatic cable feeding device separates the piled cables into single cables through a step transmission method, and transmits each single cable to the primary stripping device in turn;

[0106] The primary stripping device adaptively clamps the cable according to the cable diameter and performs primary stripping to obtain a primary stripping product; wherein the primary stripping product includes inner and outer sheaths, fillers, steel armor and wire cores;

[0107] The wire core separation and feeding device transmits and feeds the primary stripping products in layers;
