Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker bundler for collecting and binding signatures conveyed from a printing device.

[0002]

2. Description of the Related Art Conventionally, a stacker bundler has been used as a device for accumulating and binding signatures discharged from a printing device. As shown in FIG. 5, the stacker bundler 61 includes a belt conveyor (conveying device) 63, a press roller 65, and a separating device 6 which are arranged from upstream to downstream.
7, the small bundle stacking device 69 and the large bundle producing device 71, and processes the signature S as follows.

First, the signatures S ejected from the printing device (not shown) are continuously conveyed in the X direction in FIG.
After passing through 5, the folds are adjusted, and then the shaving device 67 is conveyed. The severing device 67 includes a roller 73 that is swingably supported in the vertical direction. The roller 73 temporarily blocks the flow of the signature S to prevent the signature S from flowing.
A gap is formed in the flow of. In this way, the signature S is intermittently discharged from the separating device 67 to the downstream side, discharged from the nip roller 75, and then stacked on the temporary receiving plate 77 of the small bundle stacking device 69.

When a predetermined number of copies of the signatures S are stacked to form a small bundle, the temporary receiving plate 77 is retracted from the temporary receiving position in the gap of the flow of the signatures S, and the small bundle is separated from the temporary receiving plate 77. It is transferred to the elevator 79 arranged below it. This small bundle is lowered below the small bundle stacking device 69 by the elevator 79, then pushed out horizontally by the pusher 81, and transferred to the turntable 83.
Then, on the turntable 83, if necessary, the signature S
After being half-turned so that the folds are alternated, the folds are sent to the large bundle producing device 71, and a predetermined number of small bundles are stacked and bound at the large bundle.

By the way, there are various kinds of signatures S such as a leaflet folded in a newspaper and a booklet that is piled up in a newspaper. In the process of making the signatures S into a large bundle by a stacker bundler, as shown in FIG. As shown, an end portion of the signature S that is orthogonal to the fold (hereinafter referred to as "side edge portion S1") and an end portion on the opposite side of the fold (hereinafter referred to as "edge portion S2").
There are cases in which the size of the signature is adjusted by cutting off. In order to cut off both side edge portions S1 and edge portion S2 of the signature S in this manner, the device shown in FIG. 7 has been conventionally used.

As shown in FIG. 7, the signature S ejected from the printing apparatus is conveyed with one side edge S1 at the top.
After passing through the cutting device 85 and cutting the small edge portion S2, the direction changing device 87 changes the moving direction at a right angle. Then, it passes through the cutting device 89 with the fold line at the top, and the both side edge portions S1 are cut. Thus, both side edges S
The signatures S that have been cut at 1 and the edge portion S2 are conveyed to the stacker bundler 61 described above, and are stacked and bound.

[0007]

However, in the above configuration, since two cutting devices 85 and 89 are arranged between the printing device and the stacker bundler 61, a very large installation space is required, and the equipment cost is high. There is a problem that is high. Further, as described above, since the both side edge portions S1 and the fore edge portion S2 are cut along the transport direction of the signature S, the cutting of both side edge portions S1 and the fore edge portion S2 results in
The direction of the signature S differs from the transport direction by 90 degrees. Therefore, the direction changing device 87 for changing the direction of the signature S is required between the two cutting devices 85 and 89, which causes a problem that the installation space is further increased.

The present invention has been made in order to solve the above problems, and provides a stacker bundler capable of cutting the edge portion and the side edge portion of a signature without enlarging the installation space. With the goal.

It is provided with a gutter portion 55 extending along 1a and a sweeping plate 57 that slides on the inner wall surface of the gutter portion 55 along the longitudinal direction thereof.

The pressing plate 49 is movably supported in the up and down direction by an air cylinder (not shown) above the passage opening 51 facing the cutter 45, and holds a small bundle of signatures S close to the substrate 41. It is designed to be pressed from above. A blade receiving member 59 made of resin or rubber is attached to a portion of the lower surface of the pressing plate 49 facing the cutter 45.

Next, the operation of the stacker bundler configured as described above will be described. As shown in FIG. 1, the signature S discharged from the printing device is conveyed to the first cutting device 3 via the press roller 65 with the fold line at the beginning. At this time, as shown in FIG. 2, the signature S is pressed by the first and second pressing portions 9 and 11, while the main cutter 13 and the sub cutter 37 cut both side edge portions S1. The cut chips of the both side edge portions S1 are sucked into the suction duct 15 arranged downstream of the main cutter 13.

The signature S whose side edge S1 has been cut by the first cutting device 3 passes through the cutting device 67 and is then stacked in the small bundle stacking device 69. Signatures S collected in a small bundle
Is transferred from the temporary receiving plate 77 to the elevator 79, then descends, and is subsequently horizontally moved together with the elevator 79 to the upstream side, that is, the second cutting device 5 side. As shown in FIG. 4, in the signature S, the fore edge portion S2 is arranged at a position protruding by a predetermined length L from the tooth surface of the cutter 45 to the upstream side, and subsequently, the pressing plate 49 descends to be small. Press on the top of the stack. In this state, the cutter 45 moves upward and cuts the edge portion S2 of the signature S by the length L. The cut chips W of the small edge portion S2 are dropped to the gutter portion 55 of the chip collecting device 53, and then the sweeping plate 57 slides along the gutter portion 55 to reach one end of the gutter portion 55. Is swept away.

The small bundle of signatures S with the small edge S2 cut is
The pusher 81 pushes it to the turntable 83 (FIG. 1) side, and then it is conveyed to the large bundle producing apparatus 71 and bundled into a predetermined bundle.

As described above, according to the stacker bundler 1 of this embodiment, the first and second cutting devices 3 and 5 for cutting both side edge portions S1 and the edge portion S2 of the signature S are incorporated. Therefore, in addition to the original work of collecting and binding the signatures S, it is possible to simultaneously cut both side edge portions S1 and the edge portion S2 of the signatures S. Therefore, the following excellent effects can be achieved.

That is, since a dedicated cutting device provided outside the stacker bundler as in the conventional example is unnecessary, the installation space in a factory or the like can be reduced, and as a result, the equipment cost can be reduced. it can. In addition, by the first and second cutting devices, both side edges S of the signature S are
Since the 1 and the edge portion S2 are cut along the carrying direction without changing the direction, a device for changing the direction as in the conventional example is not required, and the installation space can be further reduced. Due to this, the processing path of the signature S is shortened, and the working time can be shortened.

Further, in the first cutting device 3, the signature S is formed by the two cutters of the main cutter 13 and the sub cutter 37.
Since the sheet is cut, the side edge portion S1 of the signature S can be surely cut. The sub-cutter 37 is arranged at a position displaced from the rotation axis of the main cutter 13 to the upstream side as described above, and thus the signature S whose side edge S1 is cut is caught in the sub-cutter 37. The effect is that it can be prevented.

In the above embodiment, the cutters 13, 37,
Although the position of 45 is fixed, the position of 45 may be adjustable so that the size of the signature S can be changed. For example, the main cutter 13 and the sub cutter 37 of the first cutting device 3 may be moved in a direction orthogonal to the transport direction of the signature S so that the cutting width of the both side edge portions S1 may be adjusted. By adjusting the horizontal movement distance of 79, the cutting width of the fore edge portion S2 can also be adjusted.

Further, by operating only one of the cutting devices 3 and 5 as required, it is possible to cut only the side edge portions S1 or only the fore edge portion S2, and a signature according to various requirements can be obtained. Can be created. When it is not necessary to adjust the size of the signature, both cutting devices can be stopped. Further, in the first cutting device 3, it is possible to operate only the cutter on one side, or to provide a cutter on only one side to cut only one side edge S1 of the signature S.

In the above embodiment, the side edges S1 of the signature S are cut by rotating the disk-shaped cutters 13 and 37 in the first cutting device 3, but the shape of the cutter is not limited to this. It is not limited, and various forms can be applied.

The horizontal moving mechanism 40 of the above embodiment moves the elevator 79 in the horizontal direction to move the second cutting device 5
Although the cutter 45 is close to the cutter 45, the cutter 45 may be close to the elevator 79 side. Further, the horizontal movement mechanism may be constituted by, for example, an air cylinder, a servo motor, etc., in addition to the cam mechanism as described above.

[0033]

As is apparent from the above description, according to the stacker bundler of the present invention, the side edge portions of the signature that are orthogonal to the fold line and the end portion (edge portion) opposite to the fold line are cut. Since the first and second cutting devices are built in, in addition to the original work of collecting and binding signatures,
It is possible to cut both side edges and the edge of the signature at the same time. Therefore, a dedicated cutting device provided outside the stacker bundler as in the conventional example becomes unnecessary,
Installation space in factories can be reduced,
As a result, equipment costs can be reduced. Also,
Since the first and second cutting devices cut the both side edge portions and the edge portion of the signature without changing the direction along the transport direction, a device for changing the direction as in the conventional example is unnecessary. The installation space can be further reduced.
Due to this, the processing path of the signature is shortened, so that the working time can be shortened.
