About This Product
This is a production line dedicated to VVF cables, which are widely used for indoor wiring in general homes and buildings. We also support tandem lines where the insulation process and sheathing process are placed on the same line.
■Features
1. Increase 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: Bundle length 100m, line speed 250-260m/min when tying in two places) We also accept inquiries regarding delivery to shrink equipment (outsourced product).
2. extruder
As the line speed increases, the extrusion volume also becomes necessary. We have screw diameters up to φ150mm class as standard machines. 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． system provided
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.
4. control panel
Since both the hardware and software are designed in-house, we work together with mechanical design to build detailed system programs such as 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.
■Length control
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.
■Tension control
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.
