Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing a signature binding processing apparatus 1 according to the present invention. The left end of the drawing is a sheet feeding unit 2 for receiving signatures. Then, the sheet is sent to the section 3 and then to the direction changing section 4 through the path, and is sequentially sent to the stacking section 5 through the path. In this embodiment, a binding unit 6 is further provided via a downstream path of the stacking unit 5, and the stacked signatures are finally bound by the binding unit 6 and taken out. Up to this point, a series of operations are automatically performed. W is a signature stack.

The signature laminate W is moved from the laminating section 3 to the direction changing section 4.
A path is provided in the middle of the path to be sent to the path, in such a manner as to slightly deviate from these paths, and a toe-cut portion 7 is provided at the end of the path. This rim 7
As shown in FIG. 2, a slide plate 13 having a cutting blade 12 at an upper end portion, which is provided to be able to move up and down while being held between the upright substrate 10 and the supporting plate 11, And a press bar 14 which can be moved up and down along the upright substrate 10. The upright substrate 10 includes
A passage opening 10a is formed to avoid interference with a pusher 50 (pressing plate 50a) for pushing out the signature laminate W along the passage (see FIG. 1). The lower edge of the opening of the passage opening 10a is formed so as to be inclined so as to be higher toward the cutting blade 12 and lower at the opposite side, and the chip collecting device 8 is provided along the lower portion of the inclination. It is attached. In the chip collecting device 8, chips dropped into the gutter portion 35 are swept to one end of the gutter portion 35 by a sweeping plate 38 attached to a moving block 37 of a rodless cylinder 36. (See FIG. 7).

As shown in FIG. 3, a support member 15 which is long in the vertical direction is attached to both ends of the press bar 14, so that the whole has a gate shape. These support members 15 are formed by a conventionally known appropriate structure (not shown).
It is guided and held in the up and down direction with respect to the upright substrate 10, and is connected to the rod end of a cylinder 16 fixed to the upright substrate 10 and the like via respective connecting pieces 18. Accordingly, the operation of the cylinders 16 raises and lowers the press bar 14, and particularly exerts a downward rolling action. As shown in FIG. 2, a blade receiving member 17 made of resin, rubber, or the like is attached to the lower surface of the press bar 14 at a portion facing the cutting blade 12.

As shown in FIG. 4, a slide plate 13 having the cutting blade 12 has two long holes 21 whose longitudinal directions are obliquely inclined, and a pair of these long holes 21 which are inclined in the same direction. And a notch 22 having an open lower end. Each of the long holes 21 and the cutouts 22 is provided in the slide plate 1.
3 and penetrate the front and back surfaces of the upright substrate 1
A roller 20 provided rotatably with respect to 0 or the like is fitted therein, and a cylinder 23 fixed to the upright substrate 10 or the like is fitted in the notch 22. The rod end of the cylinder 23 is connected to a connecting piece 19 provided on the upper end side of the notch 22. Accordingly, the operation of the cylinder 23 causes the slide plate 13 to move up and down obliquely upward (about 45 °) from the lowermost standby position, whereby the cutting blade 12 has a moving component in the left-right direction. become,
The cutting power has been increased.

As is apparent from FIG.
A slide mechanism 25 is provided at a lower portion of the processing unit 1 so that the entire edge portion 7 can be pulled out to the side of the signature binding processing apparatus 1 for maintenance of the cutting blade 12 or the like. This slide mechanism 25 is shown in FIG.
As shown in FIG. 5, a guide rail 27 provided horizontally on the fixed-side frame structure 26, and is movable along the guide rail 27 so as to be attached to the upright substrate 10 of the edge cutting portion 7 via an attachment piece 31. Slide holder 29, a slide rail 29 provided in parallel with the guide rail 27 with respect to the upright substrate 10, and a fixed side frame structure 26. And a sliding guide 28 that can be freely held.
In a state in which the edge cutting section 7 is set in the signature binding processing apparatus 1 (a state before being pulled out), the sliding holder 30
And the sliding guide 28 are spaced apart from each other so as to approximately correspond to the entire width of the tongue 7, and when the tongue 7 is pulled out, the slide holder 30 is attached to the sliding guide 28. Become close. The slide mechanism 25 having such a configuration keeps the edge 7 in a two-point support state stably while keeping the overall width small (to the extent that the width of the edge 7 is not exceeded). , Large stroke (nearly twice the width of the edge 7)
It is excellent in that it can be secured.

The following structure has been adopted in order to put the signature laminated body W in and out of the edge cut portion 7 along the path. That is, FIG.
When the signature stack W is formed in the stacking section 3 as shown in FIG.
Rises, receives the signature stack W, descends, and when the elevator 40 and the direction change unit 4 become at the same level, the elevator 40 stops. In this state,
The lifting platform 40 can be moved toward the edge section 7 together with the unit (see FIG. 2). At this time, in order to prevent the stack of laminates W on the elevator 40 from collapsing or displacing the stacking condition, the direction changing unit 4 is attached to the elevator 40 (edge cutting unit 7). The pusher 50, which stands by on the opposite side, is extended in advance, so that the pressing plate 50a is brought into contact with the side surface of the signature stack W.
It is possible to move synchronously in the same direction as 0.

As shown in FIGS. 6 and 7, the unit board 41 and 51 are attached to fixed frame members 42 and 52, respectively, as shown in FIGS. 8 while being held in a freely movable state by a guide bar and a slide holder.
The drive is transmitted synchronously by cam mechanisms 43 and 53 using cylindrical cams as shown in FIG. In order to synchronize the cam mechanisms 43 and 53, power is transmitted by a timing belt 61 (see FIG. 1). 60 is a motor. FIG. 9 is a cam diagram of each of the cam mechanisms 43 and 53. One square on the vertical axis corresponds to the horizontal movement distance L of the signature stack W shown in FIG. As is clear from FIG. 9, the cam mechanism 43 for driving the lift 40 generates a movement drive for the dimension L immediately after the rotation is started, and maintains the state for about half a rotation, and then the initial state. The pattern of returning to the state is repeated. On the other hand, the cam mechanism 53 that drives the pusher 50 keeps the cam mechanism 4 until the movement drive for the L dimension is generated immediately after the rotation starts.
3, but generates and cancels (returns) the movement drive for the L dimension during the next half rotation, and then returns to the initial state in the same state as the cam mechanism 43 again. The pattern of returning to the state is repeated.

The operating state of each unit associated with the two cam mechanisms 43 and 53 will be described below together with the operation of the edge cutting section 7. In the signature stack W on the elevator 40, it is assumed that the folds of the signatures are aligned so as to face the sheet feeding unit 2 side. As described above, it is assumed that the pusher 50 has already been extended and the pressing plate 50a is in contact with the signature stack W on the elevator 40.

When the two cam mechanisms 43 and 53 start rotating at the same time, and each of them is driven to move by an amount of L, the elevator 40 is moved toward the edge portion 7 and the pusher 50 is separated from the edge portion 7. Like (towards the left side of Fig. 2)
As a result, the elevating table 40 has its moving-side tip supported by the upper end of the attachment plate 11, and the side surface (the surface on which the fold portion is aligned) of the signature laminate W is 3 to 6 in the operating area of the cutting blade 12.
The pusher 50 is in a state of being retracted toward the upright substrate 10 side of the cutting blade 12 from the cutting blade 12. Next, while the cam mechanism 43 maintains the current state, the cam mechanism 53 causes the pusher 50 to further retreat by the L dimension, so that the pressing plate 50a moves away from the side surface of the signature laminate W. become. In this state, with the cam mechanisms 43 and 53 temporarily stopped or not stopped, the press bar 14 first descends at the edge cutting section 7 to press and hold the upper surface of the signature stack W, and the slide plate 1
3, the cutting blade 12 cuts the chips, the chips are removed by the chip collecting device 8, and the slide plate 13, the press bar 14, and the chip collecting device 8 are moved back. Then, the two cam mechanisms 43 and 53 start to operate again, and first, the pressing plate 50a of the pusher 50 (which is still in the extending operation state) is brought close to the cut side surface of the signature laminate W, and then is raised and lowered. To return the platform 40 to its original position,
The elevator 40 and the pusher 50 are moved by an L dimension. The operation of both cam mechanisms 43 and 53 is completed by the completion of this movement, but thereafter, the pusher 50 performs the extension operation, and sends the signature laminate W to the direction changing section 4 along the path (see FIG. 1). Handover, and subsequently, a return movement for all strokes is performed.

It is to be noted that when handling a signature that does not need to cut the fold portion, the edge cutting portion 7 and the cam mechanisms 43 and 53 are, of course, inactive. In the present invention, the configuration in which the elevator 40 and the pusher 50 are moved together with each unit is not limited. On the other hand, the entirety is moved toward the elevator 40 on the edge portion 7 side. Is also good. In addition, the installation position and the like of the edge cutting section 7 are also arranged, for example, between the elevator 40 and the direction changing section 4, between the direction changing section 4 and the stacking section 5, or at the side position of each passage. It is possible. Of course, if the disposition of the tongue portion 7 is different, the configuration itself (for example, the moving direction of the cutting blade 12) can be appropriately changed accordingly.

[0018]

According to the present invention, the stacking device is stacked on a lift table.
Cut the fold side end of the small bundle of signatures with a cutting blade.
With this configuration, cutting is performed continuously during the signature bundling process.
Can be Therefore, the operation efficiency is extremely high without requiring any manual intervention. Then, place the cutting blade under the elevator
The standby space of the device.
Resources can be used effectively. In addition, the cutting process
When moving, the elevator was configured to move in the horizontal direction.
So, when processing without cutting process,
