Field of the Invention The present invention relates to a signature sorting device for sorting a predetermined number of signatures from a bundle of signatures in a loading operation for supplying a predetermined number of signatures to a signature storage portion of a bookbinding machine. Regarding

[0002]

2. Description of the Related Art Conventionally, a device shown in FIG. 6 is known as a device for supplying a predetermined number of signatures to a signature storage portion of a bookbinding machine.

FIG. 6 shows a signature feeder 3 arranged in the vicinity of the signature storage section 2 of the bookbinding machine 1, and the signature feeder 3 is
A table 5 for transporting the signature 4 in an upright state, a first inclined portion 6 for supplying the signature 4 on the table 5, and a state in which the signature 4 from the inclined portion 6 is in an upright position. And a second inclined portion 7 for changing its posture, and a belt 8 for conveyance is provided on the first inclined portion 6 to the second inclined portion 7. A roller 9 for pressing the signature 4 on the belt 8 toward the second inclined portion 7 is provided at a position opposite to the second inclined portion 7.

The signature 4 on the belt 8 of the first inclined portion 6 has the peller side on the front end side in the traveling direction and the fold side on the rear side. Part 6
When the belt 8 moves from the to the second inclined portion 7, the signature 4 is erected in the vertical direction due to the pressing force of the roller 9, and the signature 4 is erected and aligned on the table 5.

However, when the signature 4 is supplied to the bookbinding machine 1 by such a conventional signature feeder 3, a thin signature 4, a weak signature 4, or a signature having a small surface friction coefficient. No. 4 is liable to be crushed by the pressing force of the roller 9, clogged between the roller 9 and the belt 8 or slantedly aligned to cause a phenomenon such as diagonal alignment.
There was a problem that the signature feeder 3 could not be used.

In order to solve such a problem, Japanese Patent Laid-Open No.
In the invention entitled “Method and apparatus for supplying a book to a punching machine” of 1-64938, “a book lying on a table lifter is stacked, the table lifter is raised, and Detects the upper surface and stops the table lifter when the upper surface of the book is in a predetermined position,
After inserting the sorting pin into the print from the side of the print,
The table lifter is slightly lowered to form a gap for sorting in the print, and the conveyor is inserted into the gap. "

[0007]

However, in the case of Japanese Patent Laid-Open No. 1-64938, when the sorting pin is inserted into the printing book, the spine of the printing book is broken or the printing book is pushed out in the pressing direction. Besides, there is a problem that when stacking the printed books on the table lifter, the fold side is high and the peller side is low, and a large number of the printed books cannot be stacked, which makes it difficult to perform a large amount of sorting processing.

[0008]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to such a conventional problem as described above, and the characteristics of signatures such as thickness, flexibility, surface friction coefficient are not limited. It is an object of the present invention to provide a signature sorting device that can sort a predetermined number of signatures without having to do so, and that can sort a large number of signatures without damaging the signatures during the signature sorting operation.

[0009]

In order to achieve the above object, the signature sorting apparatus according to the present invention is capable of transferring a bundle of signatures mounted with the fold side down in the thickness direction thereof. A table having an opening penetrating the moving area of the stack of signatures, and a table rotatably supported on the back side of the table so that when the table is rotated upward, the upper end of the table projects above the opening. The rotating piece that is inserted between the signatures on the upper part and the lower part that is vertically movable below the opening, and the upper end of the rotating piece contacts the lower end surface of the rotating piece that is distant from the center of rotation. And a partition plate which is disengaged from the rotating piece and is inserted through the opening from the lower side of the table when rising.

[0010]

According to the signature sorting device of the present invention, since the folded signatures are mounted on the table, a large number of signatures can be placed on the table and the signatures can be bundled together. When the sorting plate is raised while moving in the thickness direction, the rotating piece rotates, the ridge line portion of the rotating piece projects from the opening, and the ridge line portion forms a gap between the signatures. Furthermore, when the sorting plate is raised, the sorting plate is removed from the rotating piece and inserted into the bundle of sorted signatures, so the signatures can be sorted accurately regardless of the nature of the signatures. Moreover, it does not hurt the signature.

The lower end side of the screw rod 14 is connected to the output shaft of the motor 16 via a coupling 17. A lower end of a flat partition plate 19 extending toward the opening 18 of the table 10 is screwed to the slider 15. The partition plate 19 moves up and down toward the table 10 by the rotation of the motor 16, and the upper end portion 19 a of the partition plate 19 can project from the opening 18. Upper end 19a of partition plate 19
3 has a rounded planar shape as shown in FIG. 3, but is formed so as to have an acute-angled cross section as shown in FIG. 2 and is folded when the upper end 19a projects from the opening 18. It is designed to be smoothly inserted between the claws 11, 11.

On the lower surface side of the opening 18 of the table 10,
A frame 20 facing the frame 12 is provided upright, and a rotating piece 21 is rotatably supported on a vertical wall surface of the frame 20. The rotating piece 21 is composed of a metal bent piece that is bent so that the upper end portion 21a has an acute-angled cross section, and the lower piece portions 21b and 21d are spread and face each other. The upper end 21a of the turning piece 21 is formed in an arc shape, and the upper end 19a of the partition plate 19 slidably contacts an inner wall surface 21c as the lower end of the turning piece 21.

One piece 21d of the rotating piece 21 projects downward from the other piece 21b. One piece 21d of the rotating piece 21 is rotatably supported by a bolt 22 screwed into a screw hole of the frame 20. The turning piece 21 has a turning radius such that when the turning piece 21 turns about the bolt 22, the upper end portion 19 a projects from the opening 18 from the upper surface of the table 10. The rotating piece 21 is arranged so that the frame 20 has a predetermined angle.
When rotated to the side, the upper end portion 19a of the sorting plate 19 is pivotally supported at a position apart from the rising region of the sorting plate 19 so that the upper end portion 19a of the sorting plate 19 is disengaged from the rotating piece 21 and protrudes above the table 10 from the opening 18. There is.

Reference numeral 23 is a nut, and the nut 23 is screwed into the bolt 22 to fasten and fix the bolt 22 to the frame 20. 24 is a head flange 22 of the bolt 22
The washer is interposed between a and one piece 21d of the rotating piece 21. As shown in FIGS. 3 to 5, the other end of the compression spring 25, one end of which is attached to the frame 20, is attached to the one piece 21d of the rotating piece 21. The bolt 22 is elastically urged in a direction away from the frame 20 around the bolt 22.

Next, the operation of the signature sorting apparatus according to this embodiment will be described.

First, a large number of signatures 11 are mounted on the upper surface of the table 10 with the back side facing down and the peller side facing up. At this time, as shown in FIG. 3, the slider 15 is located in the vicinity of the lower bearing 13, the upper end 19a of the sorting plate 19 is located below the table 10, and the upper part of the rotating piece 21 is located. Is in contact with the inner wall surface 21c. The rotating piece 21 is located at a position far from the frame 20 by the urging force of the compression spring 25.
The upper end portion 21 a of the above does not protrude from the opening portion 18.

When the table 10 is vibrated with a small amplitude and a high frequency by the vibrating device, the signature 11 advances toward the left side in the figure while being supported by the support plate 10a.
When the left side support plate 10a passes the sorting amount setting position P1, the space between the left side support plate 10a and the opening 18 becomes a predetermined space, and a predetermined number of signatures 11 exist between the left side support plate 10a and the opening 18. .. At this time, the motor 16 is rotated by the output signal from the detection means for detecting that the left side support plate 10a has passed the sorting amount setting position P1, the slider 15 is raised, and the sorting plate 19 is displaced upward. ..

By raising the sorting plate 19, the sorting plate 19
The upper end portion 19a pushes up the inner wall surface 21c of the rotating piece 21, and the rotating piece 21 rotates in the direction approaching the frame 20 against the biasing force of the compression spring 25. By this rotation, the upper end 21a of the rotating piece 21 is moved from the opening 18 to the table 10.
To the upper surface of. Since the upper end 21a of the rotating piece 21 has a sharp cross section, the signature 11 located on the opening 18 is
Enter between 11 folds. As a result, a gap for sorting is formed between the signatures 11 located on the opening 18. At this time, the upper end portion 21a of the rotating piece 21
Is formed in an arc shape, and the upper end portion 21a is rotated around the bolt 22.
Even if 1 is sorted, the folds of the signatures 11 and 11 are not scratched. Of course, since the ridges of the folds of the adjacent signatures 11 and 11 are sharpened by the pressing process, the pivoting piece 11 rotates so that the adjacent signatures 11 and 11 can be reliably connected to each other. Can be sorted.

When the slider 15 is raised and the sorting plate 19 is raised from such a state, the turning center of the turning piece 21 is displaced with respect to the protruding direction of the sorting plate 19,
While the rotating piece 21 further rotates, the sorting plate 19 comes off after sliding contact with the inner wall surface 21c of the rotating piece 21. When the slider 15 is further raised after the sorting plate 19 is disengaged from the rotating piece 21, the sorting plate 19 is placed on the signature 1 on the opening 18.
Enter between 1 and 11 and enter the signatures 11 and 11 on the opening 18.
Are separated. The time required for the slider 15 to be positioned near the lower bearing 13 and near the upper bearing 13 is relatively short, and the slider 11 moves at the moving speed of the signatures 11 ... On the other hand, since the signatures 11 and 11 can be sorted sufficiently, the signatures 11 on the table 10
The sorting work of the sorting plate 19 is performed in the state where the conveyance of ... Is performed.

The sorting plate 19 is provided with the signatures 11 on the opening 18.
When the table 10 is continuously vibrated after the sorting of the signatures 11 ...
The gap between the left and right signatures 11, 11 sorted by the above becomes large, and the left support plate 10a reaches the stop position P2. When the left support plate 10a reaches the stop position P2, an arm that supports the sorted signatures 11 from the thickness direction grips the sorted signatures 11 between the partition plate 19 and the left support plate 10a. To the bookbinding machine.

[0023]

[Effect] Since the signature sorting apparatus according to the present invention is configured as described above, it is possible to sort a large number of signatures on the table and perform the sorting operation for a large number of signatures. When the partition plate is raised while moving in the position direction due to vibration, the partition plate pushes the upper end of the rotating piece from the opening, so that there is a gap between the signatures located on the opening. It is formed. When the partition plate is further raised in this state, the partition plate is disengaged from the rotating piece, the partition plate is inserted between the signatures on the opening, and the bundle of signatures is sorted. As a result, the signatures can be sorted accurately regardless of the nature of the signatures, and the signatures are not damaged.
