Principle design of a "flying saw"

The material is fed-in as an endless web (e.g. plastic, sheet steel or fiber board) using a conveyor belt that runs with a constant velocity.

The position of the cut on the material web is either sensed using a print mark using a sensor or is specified by the control after a cut length has been passed that can be adjusted. The synchronous position is simultaneously defined. From this point onwards, the shears slide of the flying saw synchronously follows the material at the position to be cut and the cut can be started. After the cut has been completed, the shears slide is returned to its starting position where it waits for the next cut position.

1.2.2Solution using the standard “flying saw” application

The standard “flying saw” application discussed here can be used to implement such applications, and to develop a functioning "flying saw" as quickly as possible.

The standard application already includes, as core function, a pre- configured motion control of the flying saw axis. This can be adapted to the particular application using the appropriate parameters. The core function is responsible for completely controlling the flying saw axis.
