Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signature binding processing device required for binding signatures in a stacked state with a band or the like.

[0002]

2. Description of the Related Art Conventionally, signatures that are discharged in a folded state through a rotary press / folding machine are stacked at a predetermined height.
Laminated ones are stacked a predetermined number of times while alternately inverting each other in the front-rear direction.
A signature binding processing device has been already developed (for example, Japanese Patent Publication No. 64-301), which is capable of sending it to a binding device for hanging a band or the like, or automatically performing a series of operations including this binding operation. No. JP-A-63-171765, etc.).

By the way, some signatures have the same content printed on both sides through the folds. In this signature, it is necessary to cut off both sides by cutting the folds.

[0004]

When a signature binding processing device of the related art is used to place the signatures whose folds need to be cut as described above into a stacking state or a binding state, this apparatus is used. Take out the signature at the stage before feeding or at an appropriate position in the device (for example, at the end of the stacking work), and cut the folds by the edge cutting device installed at another place,
After that, manual intervention of returning to the original state and continuing the work is required, and there is a drawback that the operation efficiency is extremely lowered.

The present invention has been made in view of the above circumstances, and even for a signature whose fold line needs to be cut, all the steps can be automatically performed. It is an object of the present invention to provide a processing device for use.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is characterized in that the processing apparatus for binding a signature includes the stacking section and the edge cutting section.

[0007]

The fold portion can be automatically cut in the middle of the process for a signature that needs to be cut at the fold portion because it has the edge cut portion integrally formed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing a signature bundling processing device 1 according to the present invention, in which the left end of the drawing is a paper feed section 2 for receiving signatures, and the signatures are stacked through a path thereafter. It is configured to reach the section 3, then to the direction changing section 4 through the route, and to be sequentially sent to the stacking section 5 through the route. In this embodiment, a bundling section 6 is further provided via the downstream path of the stacking section 5, and the stacked signatures are finally bound by the bundling section 6 and taken out. Up to now, a series of work is automatically performed. W is a signature stack.

The signature stack W moves from the stacking section 3 to the direction changing section 4
A route is provided in the way of the route to be sent to, in such a way as to slightly deviate from these routes, and a cutoff portion 7 is provided at the end of the route. This edge cutting part 7
As shown in FIG. 2, a slide plate 13 having a cutting blade 12 at its upper end is provided between the standing substrate 10 and the attachment plate 11 so as to be able to move up and down, and above the cutting blade 12. And a press bar 14 that can be moved up and down along the standing substrate 10. The standing substrate 10 includes
A passage port 10a is formed to avoid interference with the pusher 50 (pressing plate 50a) for pushing out the signature stack W along the passage (see FIG. 1). In addition, the lower edge of the opening of the passage opening 10a is formed so as to be inclined so that the cutting blade 12 side is high and the opposite side is low, and the chip collecting device 8 is formed along the lower portion of this inclination. It is annexed. The chip collecting device 8 is configured to sweep chips that have fallen into the trough 35 toward one end of the trough 35 by a sweep plate 38 attached to a moving block 37 of the rodless cylinder 36. (See Figure 7).

As shown in FIG. 3, vertically long supporting members 15 are attached to both ends of the press bar 14 so that the entire press bar 14 has a gate shape. These support members 15 have a conventionally known appropriate structure (not shown),
The upright substrate 10 is guided and held by sliding in the vertical direction, and is connected to the rod end of a cylinder 16 fixed to the upright substrate 10 and the like via connecting pieces 18, respectively. Therefore, the operation of the cylinders 16 raises and lowers the press bar 14, and particularly exerts a downward pressing 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, the slide plate 13 having the cutting blade 12 has two elongated holes 21 whose longitudinal direction is inclined, and the elongated 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 notches 22 has a slide plate 1
The standing substrate 1 penetrates through the front and back surfaces of
A roller 20 rotatably provided with respect to 0 or the like is fitted, and a cylinder 23 fixed to the standing 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. Therefore, the operation of the cylinder 23 causes the slide plate 13 to move up and down diagonally upward (about 45 °) from the lowermost standby position, whereby the cutting blade 12 has a horizontal movement component. become,
Cutting power is enhanced.

As is apparent from FIG. 1, the edge cutting portion 7
A slide mechanism 25 is provided in the lower part of the cutting edge 12, and the edge cutting portion 7 as a whole can be pulled out to the side of the signature binding processing device 1 for maintenance or the like. This slide mechanism 25 is shown in FIG.
As shown in FIG. 5, a guide rail 27 is provided horizontally on the fixed-side frame structure 26, and is movable along the guide rail 27, and is attached to the standing substrate 10 of the cut-off portion 7 via an attachment piece 31. The slide holder 30, the slide rail 29 provided in parallel to the guide rail 27 with respect to the upright substrate 10, and the frame structure 26 on the fixed side are attached, and the slide rail 29 is moved back and forth. And a sliding guide 28 that holds it freely.
The slide holder 30 is in a state in which the trimming portion 7 is set to the signature binding processing device 1 (before pulling out).
The slide guide tool 28 and the slide guide tool 28 are arranged apart from each other so as to correspond approximately to the entire width of the edge cut portion 7, and the slide holder 30 is attached to the slide guide tool 28 by pulling out the edge cut portion 7. Get closer. The slide mechanism 25 having such a structure keeps the entire width small (to the extent that it does not exceed the width dimension of the trimming portion 7), while always stably holding the trimming portion 7 in a two-point supporting state. , With a large stroke (nearly twice the width of the edge cutting part 7)
It is excellent in that it can secure.

The following structure is adopted in order to put the signature stack W in and out of the edge cut portion 7 formed in this way 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 and descends, and the elevator 40 stops when the elevator 40 and the direction changing section 4 reach the same level. In this state,
The lift 40 together with the unit can be moved toward the trimming section 7 (see FIG. 2). Further, at this time, in order to prevent the signature stack W on the lift table 40 from collapsing or misaligning the stacking state, the direction changing section 4 is provided with respect to the lift table 40 (edge cut section 7). The pusher 50 waiting on the opposite side is preliminarily extended to bring the pressing plate 50a into contact with the side surface of the signature stack W, and the pusher 50 is lifted together with the unit to the lifting table 4
Enabled to move in the same direction as 0.

As shown in FIGS. 6 and 7, the unit boards 41 and 51 are attached to the fixed-side frame components 42 and 52, respectively, so that the lifting table 40 and the pusher 50 can be moved back and forth. On the other hand, while holding the guide bar and the slide retainer in a state of being movable back and forth,
Drives are synchronously transmitted by cam mechanisms 43 and 53 using cylindrical cams as shown in FIG. In order to synchronize the cam mechanisms 43 and 53, transmission by the timing belt 61 (see FIG. 1) is performed. 60 is a motor. FIG. 9 is a cam diagram of each of the cam mechanisms 43 and 53, and one cell 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, which drives the lifting table 40, generates the movement drive for the L dimension 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, which drives the pusher 50, does not move until the movement of the L dimension is generated immediately after the rotation starts.
Although it is completely the same as 3, the moving drive for the L dimension is further generated and canceled (returned) during the next half rotation, and thereafter, in the same state as the cam mechanism 43, the initial drive is performed again. The pattern of returning to the state is repeated.

The operation status of each unit associated with both cam mechanisms 43 and 53 will be described below together with the operation of the trimming section 7. In the signature stack W on the lifting platform 40, the folds of the signatures are aligned in the state of facing the sheet feeding unit 2. Further, 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 elevating table 40.

When both cam mechanisms 43 and 53 start rotating at the same time to cause movement movements corresponding to the L dimension, the lifting platform 40 is directed toward the trimming portion 7 and the pusher 50 is separated from the trimming portion 7. Like (toward the left side of Figure 2)
Therefore, the elevating table 40 is moved at its leading end to the upper end of the attachment plate 11, and the side surface of the signature stack W (the surface where the folds are aligned) is 3 to 6 in the operating area of the cutting blade 12.
The pressing plate 50a of the pusher 50 is retracted from the cutting blade 12 toward the standing substrate 10 side. Next, while the cam mechanism 43 maintains the current state, the cam mechanism 53 causes the pusher 50 to further move backward by the amount of L, so that the pressing plate 50a is separated from the side surface of the signature stack W. become. In this state, the cam mechanisms 43 and 53 are temporarily stopped or not stopped, and the press bar 14 first descends in the trimming portion 7 to press and hold the upper surface of the signature stack W, and the slide plate 1
3 is moved up, cutting is performed by the cutting blade 12, 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 returned. Then, both cam mechanisms 43 and 53 start to operate again, and first the pressing plate 50a of the pusher 50 (which is still in the extended operation state) is brought close to the side surface of the signature stack W after being cut, and then the lifting and lowering operation is performed. To return the platform 40 to its original position,
The lift 40 and the pusher 50 are moved by the 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 extending operation and sends the signature stack W to the direction changing section 4 along the passage (see FIG. 1). After handing over, it will start to move back for all strokes.

Incidentally, when handling a signature that does not need to be cut at the fold line, the trimming section 7 and the cam mechanisms 43 and 53 are naturally inoperative. In the present invention, the structure for moving the lifting platform 40 and the pusher 50 together with these units is not limited, and conversely, the entire structure is moved toward the lifting platform 40 on the side of the cut-off portion 7. Good. Also, with respect to the installation position of the trimming unit 7, for example, it is arranged between the lifting platform 40 and the direction changing unit 4, between the direction changing unit 4 and the stacking unit 5, or at a lateral position of each passage. It is possible. Of course, if the arrangement of the edge cutting portion 7 is different as described above, the configuration itself (for example, the moving direction of the cutting blade 12) can be appropriately changed accordingly.

[0018]

As described above, the present invention has the above-mentioned structure, and since it is provided with the trimming portion as an integral part, it is necessary to cut the crease portion for the signature. The folds can be cut automatically on the way. Therefore, no human intervention is required and the operation efficiency is extremely high.
