The main objective of this function is to be able to respond to applications consisting of:
The application therefore requires:
Principle of the "Flying Shear" Utility
The table below introduces the different stages of a cutting cycle.
Step
Action
1
The cart is in waiting position at the point of rest.
Note:The cutting value is a reading relative to the last cut made. This position is called "source control"
2
The card calculates the source control corresponding to the next cut and checks that the cut is possible.
3
When the product feed is equal to the length to be cut less a synchronization distance (in order to be synchronized at the point of synchronization), the cart accelerates and synchronizes with the controlling axis while aiming for the source control.
4
When the cart is synchronized, it remains attached in position for the whole journey.
5
When crossing the tool descent point, an output commands the cutting action.
6
Upon indication that the cut (on a sensor input or position) is finished, the tool is rechucked.
7
Upon indication that the synchro (on a sensor input or position) is finished, the cart exits slave mode and stops as quickly as possible.
8
Upon indication of a theoretical stop, the cart returns to the idle position and slowly restarts the cycle.
Solution Adapted to the TSX CAY 22 V2.0 Module
Implementation of this utility with a TSX CAY 22 module V2.0 requires the definition of:
Channel 1 supports:
NOTE: If necessary, channel 0 can support the event cutting sensor input.
If the utility is not used, the module is totally compatible with preceding versions.
