Magnetic valve receives the first level signal or second electrical level signal, is performed based on the signal received and opens or closes operation,
Wherein, when receiving the first level signal, the path between air compressor and cylinder is opened, second electrical level signal is being received
When the path closed between air compressor and cylinder.
10. control method as claimed in claim 9, it is characterised in that the raw bamboo shear is included from front to back successively simultaneously
More than or equal to 2 spoke disks of row's arrangement, wherein being provided with sensor on the spoke of a spoke disk；
The testing result signal is converted to export after second electrical level signal and specifically included to magnetic valve by the PLC：
The PLC installed in the previous magnetic valve on spoke disk by second electrical level signal lag in setting duration, and output gives institute
State the previous latter magnetic valve to spoke disk on adjacent to spoke disk.
