Abstract

PURPOSE:To securely remove a belt cut from paper leaves in a bundle by a method wherein a driving means performs both holding driving and rotating driving of a holding rotating means so that paper leaves being rotated are brought into contact with a scraping means. CONSTITUTION:When a motor 501 for holding and rotating begins to rotate toward a direction of alpha1, an arm 502 and an engaging pin 503 also rotate toward alpha1, thereby allowing an upper holding member 496 to rotate toward alpha2 opposite to alpha1 with a protrusion supporting piece 494 as a supporting point so that paper leaves are interposed between holding pieces 498, 499. When the motor 501 further rotates toward alpha1, since the engaging pin 503 has been in contact with an end of a long hole 496b, the upper holding member 496 cannot rotate toward alpha2 any more so that it rotates toward alpha1 together with a lower holding member 493. Then the paper leaves come into contact with scraping members 510 of a scraping means 406 so that numerous paper leaves are stripped off by rotation toward beta1 thereby permitting a belt remaining among the paper leaves to be scraped down.

4 to return to the initial position.

Next, the width sensor 463 of the width storage processing means 404 detects the width k in the wide portion 452.

As a result, the horizontal transfer motor 472 is started under the control of the grip processing control unit 520, and the placement plate 469 and the like are moved in the direction a.
That is, it is transferred to the wide portion 452 side.

As a result, the width k is placed on the placement plate 469.

After this, the horizontal transfer motor 472 is reversed, and the placement plate 46
Return 9 to its original position.

Next, the vertical transfer motor 483 is started, and the pressing support plate 48
6 and the band pressing piece 487 are lowered vertically downward. As a result, the band pressing piece 487 presses the width k onto the placement plate 469. Thereafter, the vertical transfer motor 483 is reversely rotated to return the band pressing piece 487 to its original position.

Next, under the control of the grip processing control section 520, the accommodation and transfer motor 474 is started, and the rotating arm 475 and the protruding pin 47 are started.
Rotate 5a. As a result, the slide lever 476
The band pushing pawl 478 also slides along the long groove 469a, and transfers the booklet k pressed onto the placement plate 469 into the small book storage box 462. It is housed in a housing box 462.

On the other hand, the sheet C from which the width k has been removed by the band removing means 403 described above is further conveyed by the grasping and conveying means 401, and eventually the two clamping members 493 of the clamping and rotating means 405
, 496.

This paper sheet C is detected by the paper sheet sensor 504,
As a result, the gripping and rotating motor 501 starts rotating in the direction of arrow α1 shown in FIG. 8 under the control of the gripping processing control section 520. Then, as shown in FIG. 9(a), the arm 502 and the engagement pin 503 also rotate in the α1 direction, whereby the bent piece 496a engaged with the engagement pin 503
At the same time, the upper holding member 496 rotates in the α2 direction opposite to the α1 direction using the protruding support piece 494 as a fulcrum. As a result, the paper sheet C is held between the holding pieces 498 and 499 provided on both holding members 493 and 496.

This state is shown in FIG. 9(b).

Furthermore, when the motor 501 rotates in the α1 direction, the engagement pin 503 is now in contact with the end of the elongated hole 496b, so the upper holding member 496 can no longer rotate in the α2 direction, and the lower side It rotates together with the holding member 493 in the α1 direction as shown in FIG. 9(C).

Eventually, the paper sheets C held by both the holding members 493 and 496 are removed by the scraping member 51 of the scraping means 406.
0, and by rotating the scraping member 510 in the β direction, a large number of sheets C are squeezed and residual bands remaining between the sheets C are scraped off.

Thereafter, the motor 501 rotates in the reverse direction to return the paper sheet C to its original position, and further releases the sandwiched state of the paper sheet C by an operation opposite to that described above.

Thereafter, the paper sheet C is sent to the paper sheet cutting means 407 by a pusher (not shown), where it is fed into the inspection device 6 in the form of one sheet at a time.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention.

[Effects of the Invention] According to the present invention described in detail above, there is provided a band removing device for paper sheet bundles that is capable of reliably removing bands from paper sheets in a bundle state due to the above-described configuration. be able to.
