VVF cable line
We also support tandem lines where the insulation process and sheathing process are placed on the same line.
1．Increased line speed
The biggest feature of our VVF line is that we can produce at a line speed 30% faster than conventional line speeds by adopting an automatic bundling device that uses our proprietary PP band binding device.
By using two miniaturized PP band binding heads, it is now possible to bind in two locations at the same time, significantly shortening the binding takt time. (Reference: Line speed 250 to 260 m/min when bundle length is 100 m and 2 places are tied)
We also accept inquiries regarding delivery to shrink equipment (outsourced products).
As the line speed increases, the extrusion volume also becomes necessary. We have standard machines with screw diameters up to φ150mm class.
In addition, when considering updating an existing line, it is expected that there will be restrictions on the installation space for the extruder, but by using a high-output type extruder, the size of the extruder can be the same as or smaller than the existing extruder. We can also make suggestions.
3． Provided system
In addition to extruders and automatic bundling machines, we design and manufacture line equipment and control panels such as supply stands, take-off machines, accumulators, water tanks, etc. in-house.As a tandem line from the insulation process to the sheathing process, We will provide the system.
Since both the hardware and software are designed in-house, we work together with mechanical design to build detailed system programs, including interlocks and interlocking controls, to meet customer requests as much as possible.
Our control system, which incorporates our unique systems such as remote management, length control, and tension control, reduces operator burden, reduces loss, and improves work efficiency, and has been highly evaluated.
Based on the product information (conductor length, product length, color, etc.) registered in advance on the recipe screen, a command signal is output to the color feeder and color change valve, and the line speed is automatically reduced to the setup speed. After the operator confirms that the color change is complete, the machine will automatically start up to production speed with a single switch.
Fine adjustments are made to the line tension registered on the recipe screen based on the actual tension data of the load cell built into the accumulator and pulling machine. This leads to improved cable quality.
