Construction of the Control System

The booklet is fed by the inlet roller, press roller, and paper delivery roller.
Each roller is driven by the feed motor (M101).
The feed block is equipped with inlet rollers and the lower inlet roller is separated by the front
estrangement motor (M103) in order to prepare for feeding of the center bound booklet. The
home position of the inlet roller is detected by the front estrangement motor HP sensor (S102).
The feeding of the booklet at the feed block is detected by the inlet sensor (S101).
The trimming block consists of trimming blade and lower blade.
The trimming blade is driven by the cutter motor (M106). The cutter motor (M106) trims by
lifting the trimming blade while drawing an arc. The home position of the trimming blade is
the same as the stop position of the cutter motor (M106). In order to accurately stop the
cutter motor (M106) which is a DC motor, the cutter motor clock sensor (S108) counts the
prescribed number of clocks to stop the cutter motor (M106).
The paper delivery block consists of registration unit, press roller, and paper delivery roller.
The registration unit registers the booklet before trimming. The registration unit is driven
by the registration motor (M102) and stopper solenoid (SL101). The home position of the
registration unit is detected by the registration HP sensor (S105).
The press roller presses the booklet when trimming. The press motor (M105) lowers the
upper press roller to press the booklet. The home position of the press roller is detected by
the press motor HP sensor (S106).
The paper delivery roller performs separation when feeding as well as feeding/ejection of the
booklet. The upper paper delivery roller is separated by the rear estrangement motor (M104)
to prepare for feeding of the center bound booklet. The home position of the paper delivery
roller is detected by the rear estrangement motor HP sensor (S104). The feeding/ejection of
the booklet by the paper delivery block is detected by the paper delivery sensor (S103). In
addition, the paper delivery roller shaft is equipped with a paddle and when the paddle clutch
lever is released by the paddle solenoid (SL102), the rotation of the feed motor (M101) is
conveyed to the paddle and rotates the paddle.
The waste paper stack block is equipped with a waste paper box detection sensor (S109) and
a waste paper full sensor (S011). The waste paper box detection sensor (S109) detects the
presence of the waste paper box. The paper waste generated by trimming is collected in the
waste paper box. The filling of the waste paper box is detected by the waste paper full sensor
(S011).
