在钢卷开平定长剪切的应用中,为了解决钢卷长度在钢卷相对于剪刀前进时加长、后退时减长的目的,首先要选用高精度的双脉冲编码器来计量钢卷走过的长度,并且要从双脉冲编码器发出的两路脉冲中,判断出编码器是正转还是反转,从而决定所接收到的脉冲应该是加长,还是应该减长,只有这样,才能实现钢卷开平定长剪切的飞剪设计。
In the application of the fixed length of the coil, in order to solve the problem that the length of the coil is lengthened when the coil is moved forward relative to the scissors, and the length of the coil is decreased during the retraction, the double-pulse encoder Of the length of the pulse from the two-pulse encoder to determine whether the encoder is forward or reverse to determine the received pulse should be lengthened, or should be reduced, the only way to achieve the coil Kaiping fixed-length shear shear design.
