Cabling-sheathing integrated equipment operation steps:

Start the twisted cable production line 1, the cable enters the long-length wire storage device 2 (the traction rope pre-wound on the wire storage rack can be used to assist in the line), and the cable is manually pulled to the inlet of the extruder. After the storage volume reaches more than 2km, the sheath production line 3 starts to operate.

The line speeds of the cable stranding production line 1 and the sheathing production line 3 are synchronously controlled by HMI+PLC, and the difference between the position information correction of the wire storage tension control dancer 7 and the wire outlet tension control dancer is superimposed.

The wire storage guide wheel group 6 is equipped with an absolute value encoder 10. The position movement of the wire storage guide wheel group 6 shows the change of the wire storage amount. The main control system maintains a suitable wire storage amount by increasing or decreasing the linear speed of the cable or sheath. If the position of the wire storage guide wheel group 6 exceeds the predetermined range, the system will send out an audible and visual alarm.

The long-length wire storage device 2 is a double-beam structure with a total length of 30m. It is installed above the area of the stranded cabling production line 1 and acts as an intermediate buffer and emergency reserve between the stranded cabling production line 1 and the sheathing production line 3. The wire storage or release is realized by the fixed guide wheel group 5 and the wire storage guide wheel group 6. Each group has 40 guide wheels and the wire storage capacity is ≥2km.

After being twisted into a cable production line 1, the cables are sent out by a double-wheel traction machine into a wire storage rack. The tension of the cables in the wire storage rack is controlled by a wire storage tension control dancer 7, and the tension range is adjustable within 5 to 50N. The movement of the wire storage guide wheel group 6 is actively translated by an AC variable frequency motor 37 + reducer 38 + sprocket chain 39, and the direction and speed of movement are feedback-controlled according to the position of the wire storage tension control dancer 7.

For example: suppose the cable storage tension is 20N, the cable core goes around the dancer for 3 circles, the storage tension controls the weight of the dancing wheel 7: 20N×6=120N, when the cabling speed = the sheath speed, the storage tension controls the dancing wheel 7 to be in the middle position of the guide rail, when the cabling speed is greater than the sheath speed, the storage tension tends to be less than 20N, the storage tension controls the dancing wheel 7 to move outward under the action of the weight, and the storage tension controls the dancing wheel 7 position +change signal drives the storage guide wheel group 6 to move outward to tighten (store the wire); when the cabling speed is less than the sheath speed, the storage tension tends to be greater than 20N, the storage tension controls the dancing wheel 7 to move inward under the action of the cable pulling force, and the storage tension controls the dancing wheel 7 position -change signal drives the storage guide wheel group 6 to move inward to relax (release the wire), the above control principle can keep the cable tension in the storage device constant.

The cable is output from the wire storage rack and is pulled into the sheath extruder by a set of double-wheel belt-pressing traction machines. The wire tension control dancer wheel controls the constant tension and runs synchronously.

The present invention has the following characteristics:

1. Cabling and sheathing are combined into one process in series, and the long-length wire storage device 2 is used for buffering and emergency reserve between the cable production line 1 and the sheathing production line 3.

2. Under the premise that the sheath production line 3 does not slow down, the process 1 of the twisted cabling production line can be stopped for up to 20 minutes to handle the connection of yarn and filling rope or other matters; when the speed of the sheath production line 3 is slowed down to 30m/min, the process 1 of the twisted cabling production line can be stopped for 60 minutes to eliminate faults, which greatly ensures the safety of integrated production.

3. High degree of automation, reducing the number of operators and lowering labor intensity.

4. The whole machine has RJ45 Ethernet communication function, which can interact with the MES network for maintenance and management, and realize remote collection, management and control of production information.

The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
