Material Loop Forming Par
Excellence. The Easy NC Loop Controller.
The Variax VLC series of loop controllers offers servo-drive technology and Sankyo's original electronic indexing expertise (commercially sold as the Camtron).
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 spring characteristics 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.
The VLC Series does what conventional loop systems (U-loops, S-loops, etc.) by enabling any type of high speed feeds to perform at their maximum. Performance variables crucial to feeding at high speeds have been solved. The length of material between the feed and the loop control rolls, the height at which the material is introduced into the loop, and the angle at which the material is discharged from the loop control are freely adjustable.
||In addition, feed pitch is adjustable between 0 and 999.99 mm, while material thickness and roll parallelism are adjusted automatically when material held by the rolls. Grip force is adjusted by the turn of a dial. The electric control provides all the functions for automatic loop control and manual jogging. The Variax Loop Control allows feeds to perform at their maximum potential, and the jogging feature reduces setup time. Installation requires only the addition of a resolver on the press crankshaft.
The advantage of installing a VLC loop controller into existing press lines are two-fold. It allows feeders to perform at their maximum potential and, by using the jog feature, reduces setup times. Installing the VLC loop controller into existing press lines is easy and straightforward. The only additional requirement is to mount a resolver on the press crankshaft.
