Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view, partially cut away, showing an embodiment of the paper sheet pressing mechanism of the present invention. FIG. 2 is a perspective view of an embodiment of the present invention shown in FIG. FIG. 4 is a side view as viewed from the direction, showing a state in which the paper sheet 16 is pressed against the abutting portion 12 by the first pressing plate 11. FIG. 3 is a side view showing a state in which a sheet 17 having a longer distance in the direction orthogonal to the longitudinal direction of the abutment guide 12 than the sheet 16 is pressed against the abutment guide 12 by the second pressing plate 8. is there.

[0008] The paper sheet 16 has a cross section of a U-shape, and one of two edges perpendicular to the direction of the stitch is in contact with the edge of the stapling guide 12 in the longitudinal direction. For example, abutment guide 1 is paired from A direction at appropriate intervals.
2 are transported by rotation of the rollers between the rollers (not shown) arranged along the longitudinal direction of the roller 2. When the center of the paper sheet 16 in the direction A reaches near the center of the first pressing plate 11 in the direction A, the upper roller of the paper sheet 16 among the rollers (not shown) is separated from the upper surface of the paper sheet 16. Thus, the displacement of the paper leaf 16 in the horizontal plane is made free. A solenoid 2 is fixed to the sheet 16 on the base plate 1 to which the lower surface of the butting guide 12 is fixed. When drive power is supplied to the solenoid 2 from outside,
Solenoid rod 2 which constitutes a part of this solenoid 2
2 is a direction 200 orthogonal to the longitudinal direction of the butting guide 12
Is displaced by a predetermined length. Further, when the supply of the driving power from the outside is cut off, the solenoid rod 22 freely moves in the direction 10 with respect to the solenoid 2 by the external force.
It can be displaced in the direction of 0 within a preset range.

The longitudinal direction of the first link 3 is orthogonal to the longitudinal direction of the butting guide 12. One end of the first link 3 is rotatably mounted near one end of a U-shaped first lever 4, and the other end is freely rotatable at a portion of the solenoid rod 22 near the abutting guide 12. It is connected to. One end of a first spring 15 is fixed to a portion of the first link 3 near the solenoid rod 22, and the other end of the first spring 15 is fixed to a first frame 21 described later. A U-shaped central portion below the first lever 4 has a lower portion fixed to the base plate 1 and a first frame 21 having a first rotation axis R1 parallel to the longitudinal direction of the abutting guide 12. It is fixed to the rotation axis R1. Accordingly, when the solenoid rod 22 is displaced in the direction 200, the first lever 4 rotates in the direction C about the first rotation axis R1. The lower part of the second lever 9 is fixed to the other end of the U-shaped end of the first lever 4, and the upper part of the second lever 9 It has a projection parallel to the direction.

The second lever 9 has a longitudinal direction in a direction perpendicular to the longitudinal direction of the abutment guide 12 and has a long hole near the center along the longitudinal direction. Is inserted. One end of a second spring 14 is fixed near the tip of the projection of the second link 9 inserted into the second link 10. The other end of the second spring 14 is fixed to an end of the second link 10 closer to the abutment guide 12.

Abutment guide 12 against first lever 4
A second rotation axis R2 and a third rotation axis R3 parallel to the longitudinal direction of the abutment guide 12 on the base plate 1 opposite to
Is fixed to the lower part of the support bracket 23 having the following.

The bottom of the second frame 20 having a fourth rotation axis R4, which is on the opposite side of the support bracket 23 from the butting guide 12 and is parallel to the longitudinal direction of the butting guide 12, is fixed to the base plate 1. ing. A lower end is fixed to the fourth rotating shaft R4, and one end of a third link 5 described later is rotatably connected to a substantially intermediate portion, and has a protrusion parallel to the longitudinal direction of the abutting guide 12 above. The third lever 6 rotating about the fourth rotation axis is the abutting guide 1
2 is located farther than the first pressing plate 11.

One end is rotatably connected to the upper end of the first lever 4 and the other end of the third link 5 having a longitudinal direction perpendicular to the longitudinal direction of the abutment guide 12 is connected to the third lever 6. Is rotatably connected to a substantially intermediate portion of the first member.

Therefore, as described above, the solenoid rod 22
Is displaced in the direction of 200, the second lever 9 rotates in the direction of C. At this time, the first pressing plate 11 rotates around the second rotation axis R2 in the direction of D and protrudes the edge of the edge of the paper sheet 16 that is farther than the abutting guide 12 from the edge perpendicular to the stitch. It will be pressed toward the contact guide 12. Therefore, even if the edge of the sheet 16 perpendicular to the stitch is not parallel to the longitudinal direction of the abutment guide 12, the longitudinal direction of the abutment guide is pressed by the first pressing plate 11 described above. Aligned in parallel.

In the state described above, the third link 5 is also displaced rightward in FIG. 2, so that the third lever 6 rotates in the direction I around the fourth rotation axis R4. Will do. Accordingly, the second pressing plate 8 is displaced rightward by the fourth link 7 so that the third rotation axis R3
Around F in the direction of F.

The elastic force of the second spring 14 is appropriately selected,
By appropriately setting the amount of displacement when the solenoid rod 22 is supplied with driving power from the outside, it is possible to prevent the paper sheet 16 from being significantly deformed when the paper sheet 16 is pressed. FIG. 3 shows a state in which the edge of the sheet 17 is pressed by the second pressing plate 8 when the interval between both edges perpendicular to the binding of the sheet 17 is larger than the sheet 16. It is shown. In this case, the first pressing plate 11 also tries to rotate in the direction of D,
Is placed in a state where the flat portion of the first pressing plate 11 faces upward and pushes the lower surface of the use upward. The pressing force on the paper sheet 17 by the second pressing plate 8 can also be pressed without significantly deforming the paper surface of the paper sheet 17 by appropriately selecting the elastic force of the third spring 13. In the above description, the state when power is supplied to the solenoid 2 has been described.
Is cut off, the first link 3 is displaced toward the butting guide 12 by the elastic force of the first spring 15. When the first link 3 is displaced toward the butting guide 12, the first lever 4 and the second lever 9 rotate in the direction B about the first rotation axis R1, so that the first pressing plate 11 Rotates around the second rotation axis in the direction of E, and the plane portion of the first pressing plate 11 faces upward.

Further, since the third link 5 is also displaced to the left in FIG. 2, the third lever 6 rotates in the direction H about the fourth rotation axis R4. Therefore, the second pressing plate 8 rotates in the direction G around the third rotation axis R3, and the plane portion of the second pressing plate 8 faces upward.

In order to achieve such a state, the elastic force of the first spring 15 and the maximum displacement of the solenoid rod 22 displaced by the first spring 15 in the direction of the abutting guide 12 must be appropriately selected. I just need.

The second lever 9, the second link 10, the third lever 6 and the fourth link 7 are moved with respect to the transfer surface along the longitudinal direction of the butting guide 12 of the sheet 16 or 17. The upper part is arranged so that it is below.

[0020]

As described above, the paper sheet pressing mechanism of the present invention can be applied to a paper sheet in which the distance between two edges perpendicular to the seam of the paper sheet is different. First and second according to
In order to press the sheet by any one of the pressing plates, the difference in the distance between the two edges described above is larger than that of a conventional sheet pressing mechanism of this type. There is also an effect that can be applied.
