A synchronous control circuit that synchronizes the rotational speed of the motor with the rotational speed of the main motor 56 of the special regular booklet opening machine 51 is housed.
Further, an operation panel (not shown) is provided at a lower position of the mounting table 78 on one side surface of the upper housing 54.

FIG. 5 is a block diagram showing a synchronization control circuit for synchronizing the rotation speeds of the main motor of the special booklet forelet feeder and the rotary collator according to the embodiment of the present invention.
The synchronization control circuit 90 is a circuit for synchronizing the rotational speeds of the main motor 56 of the special booklet fore-edge feeder 51 and the motor of the rotary collator 11.
A detection signal from the tachometer generator 87 is input to the synchronization control circuit 90. The tacho generator 87 is an apparatus that generates an AC voltage corresponding to the number of rotations of a main motor (not shown) of the bookbinding apparatus 10.

The synchronization control circuit 90 is electrically connected to the excitation winding of the synchro motor 88 installed in the rotary collator 11, and is connected to the synchro motor 62 installed in the special booklet edge feeder 51. It is electrically connected to the excitation winding.
The three-phase secondary winding (X, Y.Z) of the synchro motor 88 is connected to the three-phase secondary winding (X, Y.Z) of the synchro motor 62, respectively.

  The excitation winding of the synchro motor 88 is supplied with an excitation current from the synchronous control circuit 90, and operates as a power generator. The synchro motor 88 generates a predetermined AC voltage in the three-phase secondary windings (X, Y, Z) according to the rotational speed of the rotary collator 11, and generates the AC voltage for the three-phase secondary of the synchro motor 62. Each of the windings (X, Y. Z) can be supplied. When the rotation speed of the synchro motor 62 is different from the rotation speed of the rotary shaft of the rotary collating machine 11, an error voltage corresponding to the different rotation value is generated in the excitation winding of the synchro motor 62. The error voltage is supplied to a later-described displacement detector of the synchronization control circuit 90.

  The synchronization control circuit 90 rectifies the detection signal from the tachometer generator 87 to obtain a DC voltage corresponding to the rotation speed, and a signal adjuster 92 that outputs an adjustment signal corresponding to the DC voltage from the rectifier 91. And a displacement detector 93 that detects the displacement from the adjustment signal from the signal adjuster 92 and the error voltage related to the rotational speed from the synchro motor 62 and forms an inverter control signal that eliminates the displacement. Has been.

The inverter control signal from the displacement detector 93 in the synchronous control circuit 90 is supplied to the inverter 89. The inverter 89 can drive and control the main motor 56 of the rotary collator 11 by forming an AC voltage based on the inverter control signal.
The operation of the special booklet fore edge feeder 51 configured as described above will be described. First, as shown in FIG. 3, the special printing book 100 is set on the mounting table 78 with the back of the special printing book 100 on the left side in the drawing and the small edge side of the special printing book 100 on the right side in the drawing. Also for the rotary collator 11, a printed book (cover) 12 is set on the mounting table 13 in a predetermined direction.

Next, the power of the rotary collator 11 and the special booklet edge feeder 51 is turned on, the rotation of the rotary collator 11 and the special booklet edge feeder 51 is synchronized, and the collation start switch is pressed.
Then, on the rotary collator 11 side, the printing book (cover) 12 of the mounting table 13 is conveyed by the rotary drum 15 and carried to the tray 16 at a predetermined timing.
On the other hand, on the side of the special booklet mouthlet feeding machine 51, the vacuum octopus 81 moves to the takeout port 80 side of the mounting table 78, and when it reaches a predetermined position, vacuuming is started, and one special booklet 100 is taken out. Then, carry it out to the rotary drum 69 side. When the vacuum octopus 81 reaches a predetermined position, the gripping claw 70 of the rotary drum 69 grips the back portion of one special booklet 100. Since the rotary drum 69 rotates at a predetermined rotational speed toward the arrow shown in the figure, one special printed book 100 is pulled out from the mounting table 78 and is carried to the special printed book dropping receiver 71 side.

When the rotary drum 69 rotates and the gripping claw 70 reaches the position of the special printing book drop receiver 71, the gripping state of the gripping claw 70 is released. As a result, the single special booklet 100 is dropped into the special booklet dropping tray 71 and placed on the chain feed conveyor 72.
When the chain feeding conveyor angle 73 of the chain feeding conveyor 72 hits the back of one special printing book 100, the one special printing book 100 is moved by the action of the chain feeding conveyor 72 into the tray 16 of the rotary collating machine 11 in the direction indicated by the arrow. Conveyed to the side.

Then, one special printed book 100 passes between the lower delivery roller 74 and the upper delivery roller 75 and is fed into the tray 16 of the rotary collator 11.
The above operation is repeated at a predetermined timing. In this way, the special printing book 100 is reliably collated.
After collation, the back portion of the special booklet 100 is cut by a predetermined value to finish a normal book.
