and a drive wheel 6b (I), and is configured to rotate in the direction of the first arrow B shown in the figure when the drive wheel 6h, which is connected to the transport motor 5CK via a coupling 6B, is driven. i am doing Note that the surface of the horizontal conveyance belt 31 is made of a material having a small coefficient of friction to the extent that the paper sheets placed thereon can be moved horizontally. When a group of sheets P is transferred from the first conveying means 1 configured as described above to the second conveying means 3, this group of sheets P is tipped over via the inclined guide 2. Therefore, the paper sheet group PK is subjected to some degree of impact.

The alignment unit 4 that aligns the sheet group fallen on the second conveying means 3 and the stamping unit 5 that stamps the strip material BVC of the sheet group P are configured to be operated by one drive source. It's wandering. The alignment section 4 adjusts the position of the sheet group P on the second conveying means 3 in the traveling direction (the position along the longitudinal direction TL of the horizontal conveying belt 3A) and the position (along the longitudinal direction TL of the horizontal conveying belt 3A) and the position ( 5 (Position along the transverse direction Vc of the horizontal conveyance belt 3A)
It regulates the For example, an alignment guide support shaft 6 is attached to the alignment section 4 at a pace (not shown) f'L5, and the alignment guide shaft 6Vc is connected to an auxiliary lever 7A, ! - The alignment guide drive lever 7B and the two levers 7A are swingably supported.

A positioning guide 8 is attached to the distal end of 7B. This alignment guide 8 includes a leading edge position regulating part 8A that regulates the position of the sheet group P in the traveling direction, a side position regulating part 8B that regulates the position perpendicular to that direction, and an inclined surface that is the same as the inclined surface of the inclined guide 2. It is arranged so that it can swing in the lateral direction on the horizontal conveyor belt 3A by swinging the alignment guide drive lever 7B. A side guide 9 is attached to a base (not shown) at a side end of the horizontal conveyance belt 6A at a position opposite to the side position regulating portion 8BVC of the alignment guide 8. And, such alignment guide 8
In order to swing the alignment guide drive lever 7B, first

Furthermore, a drive source, for example, a motor 11, is provided near the other end of the alignment guide drive lever 7B. A drive disk 12 is attached to the motor axial pressure.

A guide roller 16 that can be stopped at the other end of the alignment guide drive lever 7B is rotatably supported on the back side of the drive disk 12. This guide roller 13 is attached to the other end of the alignment guide drive lever 7B. When the section is pushed down to the lowest end, the inclined section 8 of the alignment guide 8 is pushed down as shown in FIG.
C coincides with the inclined surface of the inclined guide 2 (
(Hereinafter, this position of the alignment guide will also be referred to as the standby position). The stamp section 5 stamps the processing date of the strip material BVc, the name of the handler, etc. of the sheet group P that has been aligned by the alignment guide 8 and the side guide 9. For example, in this stamp section 5, two stamp holder guide shafts 15 are attached vertically downward at a pace (not shown). It is located above f. A stamp holder 17 to which a stamp 16 is attached is provided on the stamp holder guide shaft 15 so as to be movable up and down. Further, a stamp holder pin 18 protrudes from the back surface of the stamp holder 17. and the stamp holder 1
In order to move the stamp 7 up and down, a stamp drive arm 20 is provided, one end of which is swingably supported by a support pin 19. A cutout 2OA is provided at the other end of the stamp drive arm 20. The stamp holder pin 18 is inserted into the cutout 20A, and the stamp holder pin 18 is inserted into the cutout 2OA to prevent the swinging movement and movement of the stamp drive arm 20.
It is designed to convert into linear motion. A long hole 2OB is provided in the middle part of the stamp drive arm 20, in which one end of the stamp drive bin 21 is inserted. It is attached to the front side of the drive disk 12. The mounting position of the stamp drive bin 21 with respect to the drive disk 12 is approximately 180 degrees apart from the mounting position of the guide roller 16, and the alignment guide 8 is in the standby position shown in FIG. , the stamp holder 17 is located at the top.

In order to detect this state, a sensor grate 26 is attached to the middle part of the stamp drive arm 20, and a standby position sensor 24 for detecting this sensor grate (25f) is attached to a base pressure device (not shown). .

Furthermore, the paper sheet group P is transported by the second transport means 6.
For example, a reach detection saw is an example of a reach detection means for detecting the arrival of an object. -24A and the arrival detection receiver -24B are arranged opposite to each other with the second conveying means 6 in between. Note that the light emitted from the arrival detection saucer 24A is configured to pass through a position lower than the upper end surface of the sheet group. Further, as a bundle state detecting means for detecting the bundle state of the paper sheet group conveyed by the second conveying means 31C, for example, a thin bundle state detection saucer 254 and a bundle state detection receiver 25B are used as the second bundle state detection means. They are arranged opposite to each other with the conveying means in between. Note that the light emitted from this bundle state detection saucer 25A passes through a position slightly higher than the upper end surface of the sheet group P, and the strip material B that bundles the sheet group P is peeled off. When I was climbing up, I was blocked by that part.
That will happen. Although not shown, the light emitted from the saucers 24, 4, 25A is transmitted to the receivers 24.
The alignment guide 8 and the like are provided with appropriate passage holes so that the light can be received by the light beam B, 251).

Next, the operation of the apparatus of the present invention will be explained with reference to FIG. 2 and No. 61.

First, as shown in FIG. 1, a bundle of paper sheets P is conveyed in an oblique manner by the first conveyance means 1TIC. Note that at this time K, the alignment guide 8 is in the standby position, and the stamp 16 is located at the top of the stroke. Then, the sheet group P is transferred to the bottom conveyor belt 1A and the side conveyor belt) IZ? As the sheets are pushed out, they are gradually guided to the inclined guide 2, and when approximately half or more of the length along the longitudinal direction of the sheet group P is extruded, the sheets are pushed out by their own weight onto the horizontal conveying belt 6A. Fall down. As a result of trapping and knocking down the paper sheets in this way, a certain amount of impact acts on the paper sheets, and as a result, the bundle state detection means described later detects that the belt-shaped material B holding the paper sheets P has received an impact of this degree. Strict bundling state detection is performed in the sense of whether or not the bundle has a cohesive force of 4'J.

For example, the picked up paper sheet group P is the horizontal conveyor belt) 3, 4.
Conveyed by 扛. The arrival detection receiver 24B detects the arrival of the paper group P by being interrupted by the light emitted from the arrival detection sensor 24A during the conveyance. Upon this detection, the drive of the transport motor 3C is stopped. and horizontal conveyor bell as shown in Figure 2)
Immediately before the sheet group 5A completely stops, the leading end of the sheet group P comes into contact with the leading end position regulating portion 8AK of the alignment guide 8, and the stopping position of the sheet group is regulated.

Thereafter, the bundle state detection saucer 25A is driven. At this time, when the strip material B of the sheet group P is being peeled off, the light emitted from the bundle state detection saucer 25A is blocked, and as a result, the bundle state detection receiver 25B
An abnormality in the bundled state is detected through this. At the same time as this detection, the motor 11 is driven and the drive disk 12 is rotated in the direction of the first arrow in the figure.

When this is done, the guide row 216 provided on the drive disk 12 separates from the end of the alignment drive lever 7B with which it is engaged. As a result, the biasing force of the upward biasing member 10 causes the alignment guide 8 to rotate together with the alignment drive lever 7B in the direction of the second arrow C in the figure.

Then, the side position regulating portion 8B of the alignment guide 8 pushes the side of the stopped sheet group P, and as shown in FIG. Let the Yokocho bell ring until they touch each other.

In this process, the sheet group P is not aligned, and the sheet group P is stopped when the band material B holding the sheet f'L is positioned below the stamp 16.

That will happen. Further, when the motor 11 is driven, the stamp drive bin 21 also rotates together with the drive disk 12, so the stamp drive arm 20 rotates downward about the support bin 19. As a result, the rotational movement of the stamp drive arm 20 is converted into a linear downward movement of the stamp boulder, and the stamp 16 attached to the stamp holder 17 gradually approaches the sheet group PVc. and said drive disk 1
2 rotates approximately 180°, the strip material H of the sheet group P
stamped on. Further, the drive disk 12 is the sixth drive disk.
Rotate the stamp holder 1 in the direction of the arrow shown in the figure.
7 is contrary to the above, the direct Kd-like trap rises.

Then, in the middle of the process, it is not attached to the drive disk 12.
The guide roller 16 is connected to the alignment guide drive lever 7.
B, and rotates this alignment guide drive lever 7B against the biasing force of the biasing member 1o. When the drive disk 12 further rotates and the alignment guide 8 returns to the standby position shown in FIG. 1, the standby position sensor 24 detects the sensor plate 23 to which the stamp drive arm 2 is attached. As a result, the drive of the motor 11 is stopped. In this way, the alignment guide 8 and the stamp 16 are returned to the position shown in FIG. 1 again. Then, by driving the conveyance motor 3C, the sheet group P on the horizontal conveyance bell)
is discharged. (9) Although not shown, the ejected paper sheets are sorted into good ones and bad ones based on the detection result by the bundle state detection means. In addition, if a group of sheets in a normal bundle state is sent to other processing after being ejected from the apparatus of this embodiment, the bundle state is strictly detected as described above. If the strip material is removed, the processing efficiency will not be significantly reduced.

In addition, in the apparatus described in the above embodiment, alignment and stamping of the sheet group can be performed with a single drive source, and moreover, the sheet group can be aligned and stamped with a single drive source, and moreover, The stopping position in the direction perpendicular to the direction can be achieved using one alignment guide and one fixed guide, and furthermore, in order to regulate the stopping position of the sheet group, the sheet group is horizontally aligned on a horizontal conveyor belt. This has the unique effect of contributing to the compactness of the device and its specific pressure.

It should be noted that the above embodiment is just an example, and it goes without saying that each member may be replaced with another member VC having the same function.

Note that the arrangement of the first conveyance means and the second conveyance means is not limited to this embodiment, and may be any suitable arrangement that does not cause impact during the delivery of a group of paper sheets. . In addition, although this embodiment describes the case where bundles of paper sheets are transported, the present invention is not limited to this, and the case where bundles of sheet films, packages, etc. are used as the bundle is applicable. It is also possible to do so.

Further, the tilting means is not limited to a fixedly arranged inclined guide, but it is also possible to replace the guide belt or the forcibly bound body with a folding button or the like.

〔Effect of the invention〕

As is clear from the above description, the bundle conveying device of the present invention has a relatively simple configuration, and therefore can accurately detect the bundling state of the bundle, and This has excellent effects such as being able to contribute to improving the processing efficiency of the bundled bodies.
