3.8.3.2 Features
Synchronous Capture Axis
Synchronous capture axis applying here is to ensure it can automatically adjust its motion and
overcome the problem of incorrect packaging and wrong cutting position when master axis
(material feeding axis) transmits the abnormal pulse to the slaves (film feeding axis and cutter
axis).
In flying shear application, camshaft operates in accordance with the operational distance set by
the receiving pulse of master axis. Therefore, if the master axis is unable to output the set pulse
length, slaves will be unable to cut or pack in correct position. See figure 3.8.4. Assume the salve
axis is set to perform the cutting operation after receiving every 10000 pulses from the master
axis. If the master axis moves the same distance and pulses transmitted are fixed to 10000, then
the camshaft will not go wrong on cutting. If the master axis moves the same distance, but the
slave axis receives 11000 pulses instead of 10000 pulses, the slave axis will still perform the
cutting operation when receiving the 10000
th
pulse and it will therefore have shorter cutting
length. If the master axis moves the same distances, but the slave axis receives 9000 pulses
instead of 10000 pulses, the slave axis will perform the cutting operation when receiving the
10000
th
pulse and it will therefore have longer cutting length.
