FIG. 2 schematically shows the feeder unit A described in FIG. 1, and as can be seen from FIG. 2, a plurality of feeder units A are installed along the collating unit B. A plurality of fingers 8 for transporting the sheet-like material S conveyed from the feeder unit A are running, and the sheet-like materials S sequentially supplied from each feeder unit A are sequentially overlapped and collated. ing.

A binding mechanism in a conventional flat stitching machine will be described with reference to FIG.

FIG. 3 is a perspective view showing a binding device. In the drawing, reference numeral 11 denotes a device called a clamp for grasping a bundle of collated sheets S, and a plurality of them rotate and rotate. . Note that, in the figure, the clamps during the return path (upper stage) are omitted. A milling section 12 is provided in the outward path (lower section) to cut and roughen the lower end of the bundle of collated sheets S to improve the adhesion of the glue. Further, there is a gluing section 13 that glues the lower end of the bundle of sheets S from the glue tank using a roller. Then, between the forward path and the return path, a cover sheet supply unit 1 for taking out and supplying the cover sheets S 'one by one from the bundle of cover sheets S'
4 are provided. A claw 15 is provided on the return path to convey the supplied cover sheet S '. That is, the pawl 15 moves so as to push the cover S ′ in, and cooperates with the clamp 11 which has grasped the bundle of the glued sheet S, thereby moving the cover S ′ at substantially the center of the sheet S.
To be stuck on a bundle. Reference numeral 16 denotes a crimping portion for attaching the attached cover S ′ to the bundle of the sheet-like materials S. The crimping portion 16 crimps the back portion with the flat plate 17 and also crimps the side surface with the swinging flat plate 18. After the cover S 'is attached in this way, the clamp 11 is opened, and the bundle of the sheet-like materials S is transported to the subsequent process with the cover S' attached.

[0006]

In the above collating device,
As can be seen from FIG. 2, since the feed direction of the finger 8 is orthogonal to the supply direction of the sheet material S, for example, when handling a small sheet material S, the belts 5, 6 in FIG.
May be thrown out of the nip and slide down on the table 7, bounce below the table 7 and cannot be fed well by the finger 8. In addition, finger 8
In order to push the sheet material S, it is desirable that the pitch between the fingers 8 be reduced because the speed of the finger 8 at the same production speed can be reduced. Finger 8
Therefore, even when a small sheet-like material S is handled, it must be operated at a large pitch.

[0007] The same applies to the binding device.
That is, since the width of the clamp 11 is set in accordance with the maximum size of the sheet material S to be handled, when the small sheet material S is handled, if the small clamp is used, the clamp 11 is fed at the same production speed. The speed can be reduced, and the machine speed can be reduced in each of the steps of the milling section 12, the gluing section 13, the cover sheet supply section 15, and the press-bonding section 16. This is desirable. As a result, the machine speed of each process was increased, which caused the production speed to plateau.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to adopt a completely different feeding system from the conventional one, to reduce the pitch, and to form a bundle of sheet-like materials. An object of the present invention is to provide a bookbinding machine provided with a collating device and a binding device capable of reducing the load on a sheet-like material due to a change in the amount of exercise and realizing a significant increase in production speed.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a side view showing an example of a collating apparatus used in the bookbinding machine of the present invention.

In FIG. 4, reference numeral 21 denotes one of the endless chains 20.
The fingers 21 constitute at least two rows in the direction perpendicular to the plane of the drawing.
Forming a tray for holding. The endless chain 20 travels from left to right in the figure, and in cooperation with this traveling operation, an arm 22 having an octopus swings, and only one sheet S from the bundle of sheets S above is moved. Turn over. Immediately after this, the finger 21 separates the rolled sheet material S from the bundle, and finally, after completely separating, the sheet material S falls down so as to lean against the back of the finger 21 by gravity. Then, the same operation is repeated in the next station, so that the sheets S are collated.

FIG. 5 is a side view showing a joint portion of a collating device and a binding device (described later).

As shown in FIG. 5, the sprocket 23 of the receiving endless chain 20 in the collating device is located below the sprocket 34 of the receiving endless chain 30 in the binding device. The reason for this is that the fingers 21 forming one piece of the endless chain 20 are inclined in the traveling direction, so that the point at which the fingers 21 become horizontal is slightly above the center of the sprocket 23, Base plate 3 of clamp 31 of device
Since 2 is vertical, it will be horizontal when it is flush with the center of the sprocket 34. Then, the finger 21 and the clamp 31 are properly fitted to each other at a point where they are horizontal. In order to be fitted as described above, the finger 21 and the clamp 31 need to have a gap so as to be nested with each other. In FIG. 5, the pitch of the fingers 21 and the pitch of the clamps 31 are substantially the same, but the fingers 21 on which the collated sheet-like materials S are placed are hooked on the sprockets 23, and when they are horizontal, the fingers 21 For the delivery, the pitch of the fingers 21 is wider than the pitch of the clamps 31;
If the speed is faster than the speed, the delivery will be performed smoothly.

FIG. 6 is a schematic perspective view showing a binding device used in the bookbinding machine of the present invention.

As shown in FIG. 6, the endless chain 30
At least one or more clamps 31 are mounted thereon. The clamps 31 include a fixed base plate 32 and a swinging clamp plate 33. The lower and upper ends of the endless chain 30 allow the clamp 31 to run straight by rails (not shown). In particular, the lower rails need to be made particularly strong because of the operations of milling, gluing, and attaching a cover, which will be described later. A milling part 40 and a gluing part 5 are provided below the endless chain 30.
0 and the cover attaching unit 60 are arranged. FIG.
In order to facilitate understanding, these devices are drawn below their original positions. Here, the basic mechanism of the milling unit 40 and the gluing unit 50 is the same as that of the conventional apparatus, but it is necessary to provide a width sufficient for milling and gluing over the entire surface of the sheet. Since the cover attaching section 60 is a completely different mechanism, it will be described in detail below.

FIG. 7 is an explanatory diagram of a cover attaching portion in the binding device.

In FIG. 7, reference numeral 61 denotes a take-out drum for taking out the cover S 'one by one from the bundle of cover and transferring it to the pressing drum 62. Here, an arm 63 having an octopus is used as a means for separating one cover sheet S 'from the bundle of cover sheets. The cover S ′ may be supplied sequentially. The pressing drum 62 receives the cover S ′ from the take-out drum 61.
And rotate as it is. Then, the clamp 31 arrives when the cover S 'has just arrived at the pasting position, and the lower end of the bundle of sheets S coincides with the upper part of the pressing drum 62, so that the temporary crimping is performed at this moment. It has become. Here, the claws 64 are opened, but the cover S 'is blown up with high-pressure air so as not to drop.

After the cover attaching step described with reference to FIG. That is, the cover attaching portion 60 has a crimping portion, and FIG. 8 is an explanatory diagram of the crimping portion. As shown, the crimping portion includes an endless chain 70 and at least one or more clamps 71 thereon. The clamps 71 support the bundle of the sheet-like materials S and the cover S ′ temporarily bonded to the bundle at the back. And a pair of side clamps 73 for clamping and tightening from both sides. These side clamps 73 are rocked and fastened to smoothly bend the cover S ′ according to the shape of the bundle of the sheets S. Then, when the bundle of sheets S to which the cover S ′ is temporarily adhered to the lower portion comes to the crimping portion while being clamped by the clamp 71 of the binding device, the bundle is held by the clamp 71 of the crimping portion and the cover S ′ is crimped. Then, the bookbinding is completed and transferred to the discharge unit.

[0022]

As described above, in the case of the conventional bookbinding machine, the speed of the collating device and the binding device itself is high, and it is difficult to further increase the speed. However, according to the present invention, the collating device is used. Since the bundle of sheets can be sent with the pitches of the trays and clamps reduced in the binding device, the speed can be increased, and the production speed can be greatly increased.
