Producing the ideal material loop.

VSC series
VSC70/150/400

VLC series
VLC50/150/400

Features● Employ the high-resolution high-torque servo motor drive.
● To eliminate the bending of the material near the entrance loop.
● Possible to supply-eject the material at creep speed.
● Feed conditions are set by full-color touch screen.
● Integrating a leveler function that corrects the rolling habits of a material.

Sankyo developed the NC loop controller in order to create the ideal loop shapes
required by the feeding device, using servo technology. This VLC sets up optimum
feeding by forming ideal loops in the space allowed, taking advantage of the springcharacteristics of materials and stabilizing the loop using a sensor and servo
control. The VLC has excellent handling characteristics in that it does not scratch,kink or dent material and can improve both quality and productivity.

Uncoiler（VUC series）
Supplies material at high speed,excellent tracking ability and stability
An unwinder with excellent high speed and tracking that we developed to provide a stable material supply to our original loop controller. Suitable for speeding up a feed line.
A servo motor is connected to the rotating part. It unwinds the coilmaterial to supply it in real time, according to the press rotation
speed.
In addition, there is a swing arm that contacts the outer circumference of the coil material. It automatically measures the radius of coilmaterial. Therefore, you can control the feeding according to theremaining amount of material, resulting in outstandingly stable
operation.

Technical data

Loop controller adjustment mechanism
Variax VLC series and VSC series loop controllers have amechanism for adjusting the roll height, roll tilt, sensor position anddistance to the feeder.
The purpose of these adjustment mechanisms is to optimize theshape of the material feed loop being sent to the feeder according
to various conditions such as the size of the material to be used,
the type of material, specifications such as the feed length androtation speed, and the layout of the press line.
The feeder is capable of high-speed operation by automaticallyadjusting settings for the feed length, material thickness, gripping
force, material width, and the feed line height.
As the feeder speed increases and the types of products produced
increase, it becomes necessary to make the shape of the loop ofmaterial supplied to the feeder match the current conditions.
If this loop shape is inappropriate, the material may bend duringhigh speed operation and may not make usable products. Also, thematerial may flutter and increase the load on the feeder, resulting inmisfeeding.

●Advantages of adjusting the roll height andangle of both rolls.
The material loop R can be changed by changing the material
thickness setting, the material and feed length settings, and thefeed line height can be changed easily.

●Advantages of sensor position adjustment

The sensor monitors the shape of the loop, and if the loop R
becomes too small, it speeds up the material feed rate to the loop,
increasing the loop R to maintain the optimum loop shape.
If loop R gets too large, the opposite happens.
If the loop shape cannot be maintained due to a problem, thesystem is protected by an emergency stop of the press because theloop controller is interlocked with the press.
It can be set at the appropriate position for each condition, such as
the size of loop R, the material feed angle, feed length, etc.

By using Variax's loop controller, these automatic adjustments
create the optimum material loop shape, fully exploit the originalcapabilities of the feeder, and enable high-speed press production
operation.
