Is released and the guide rail 57 returns to its normal position,
This is confirmed by the pusher home sensor 72.

In this way, a series of work operations are repeated until the preset amount set by the operation unit is completed. When the preset amount is completed, the operator is informed of the completion of the preset amount by the display unit (not shown), while the polishing is performed. Mechanism 301 and dust collector 401
Stops.

Next, the polishing work process will be described. When the grip of the book by the hand unit 201 is completed, the power source (not shown) of the Y-axis linear drive mechanism 16 shown in FIG.
The hand unit 201 is moved (raised) to the Y-axis home sensor 18b side to a position where the front edge r of the book does not interfere with the pusher finger 58.

Thereafter, a power source (not shown) of the X-axis linear drive mechanism 12 is activated to move the Y-axis linear drive mechanism 16 toward the X-axis end sensor 14c, and the small edge s or the small edge t of the book pushes the pusher of the buff 303. It stops at a position in contact with the surface on the side of the portion 52. Next, a power source (not shown) of the Y-axis linear drive mechanism 16 is activated to move the hand portion 201 up and down to polish the edge s or edge t of the book.

At this time, the number of reciprocations of the hand unit 201 is set in advance in a control unit (not shown), but after reaching the set value, the axis of the check plate 227 in FIG.
Y-axis linear drive mechanism 1 at a position that coincides with the center axis of 03.
6 and the drive motor 319 are stopped. Then, after a certain time has elapsed, the power source of the X-axis linear drive mechanism 12 is activated to move the Y-axis linear drive mechanism 16 toward the X-axis end sensor 14c, and the check plate 227 causes the buff 30 to move.
When the sensor 231 detects that the X-axis linear drive mechanism 12 is in contact with the power source 3, the power source of the X-axis linear drive mechanism 12 is stopped. This makes buff 3
03 wear amount is checked and the buff 3
The polishing position where 03 and the small edge r, s, t of the book contact is corrected.

When the correction is completed, the power source of the Y-axis linear drive mechanism 16 is reversely operated to raise the hand portion 201,
Further, the power source of the X-axis linear drive mechanism 12 is activated to move the hand portion 201 by a certain amount in the direction of the X-axis end sensor 14c to bring the fore edge r of the book into contact with the upper surface of the rotating buff 303. Then, the X-axis linear drive mechanism 12 reciprocates the Y-axis linear drive mechanism 16 to polish the edge r of the book. At this time, the left sensor 4 detects the book end dog 209 to confirm the end surface positions of the fixed chuck slide plate 204 and the movable chuck slide plate 212. This is to prevent the fixed chuck slide plate 204 and the movable chuck slide plate 212 from colliding with the buff 303 due to an error in setting the length F of the book by a worker during work.

On the other hand, when the polishing of the small edge r is completed, the X-axis linear drive mechanism 12 moves Y toward the X-axis end sensor 14c.
The axis linear drive mechanism 16 is moved. Then, the power source of the Y-axis linear drive mechanism 16 is activated again, and the hand portion 201 is moved up and down, whereby the small edge s or the small edge t of the book is polished by the buff 303. After the polishing is completed, the booklet stops at the position where the fore edge r of the book faces the upper surface of the buff 303.

Next, the X-axis linear drive mechanism 12 moves the Y-axis linear drive mechanism 16 toward the X-axis home sensor 14b, and the Y-axis linear drive is performed at a position where the fore edge r of the book exceeds the center axis of the buff 303. The power source of the mechanism 16 is activated to raise the hand portion 201 to a position where the edge r of the book does not interfere with the pusher finger 58.

Then, the hand section 201 is replaced by the pusher section 52.
When it reaches the top, the X-axis linear drive mechanism 12 stops,
Immediately after that, the Y-axis linear drive mechanism 16 is slightly lowered, the edge r of the book is brought into contact with the upper surface of the pusher portion 52, and the operation of the hand portion 201 and the delivery portion 51 is started.

Here, in the description of the above-mentioned embodiment, the small edges r, s, t of the book are polished back and forth, but it is also possible to polish only the forward or backward. In the above embodiment, the length of the book is adjusted by the operator operating the knob 85, but this can be easily automated by adding a power source such as a motor. A book can also be automatically fed by adding a feeder.
