Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting device for sorting a predetermined number of signatures from a bundle of signatures in the work of mounting a bookbinding machine.

[0002]

2. Description of the Related Art As a signature supply device for a bookbinding machine, one shown in FIG. 12 is known. A signature feeder 3 installed in the vicinity of the signature storage unit 2 of the bookbinding machine 1, and the signature feeder 3
Is a table 5 for transporting the signatures 4 in an upright state, and a second table for changing the signatures of the inclined portion 6 from the lying state to the upright state.
The inclined portion 7 is provided, and the conveyor belt 8 is provided between the first inclined portion 6 and the second inclined portion 7. Second inclined portion 7
A roller 9 that presses the signature 4 on the belt 8 toward the second inclined portion 7 is provided at the opposite position.

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, the signature feeder 3 is used to bind the bookbinding machine 1.
When the signature 4 is fed to the sheet, if the signature is thin, the stiffness is weak, or the friction coefficient of the surface is small, the pressing force of the roller 9 makes it crunchy.
There is a problem in that the signature feeder 3 cannot be used because phenomena such as jamming between the sheet and the sheet and slipping due to one-sided slippage are likely to occur.

In order to solve such a problem, in the invention described in Japanese Unexamined Patent Publication No. 1-64938, "Method and apparatus for supplying signatures to a signature punching machine", a folded signature is laminated on a table lifter, After raising the table lifter and detecting that the upper surface of the printing plate has come to a predetermined position by the photoelectric tube, stopping the rise and inserting the sorting pin into the signature,
The table lift is slightly lowered to create a sorting gap and the conveyor is inserted, but when the sorting pin is inserted, the spine of the signature is broken, and it is pushed out in the pressing direction. Since the heights of the fold side and the peller side are different when the chomes are stacked side by side, it is difficult to perform a large amount of sorting processing.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a signature sorting device that reliably sorts a signature without damaging the signature. To do.

[0007]

In order to solve the above problems, the present invention provides a signature sorting apparatus for moving a signature sorting apparatus with a folded erected signature in a state of closely contacting in the thickness direction. An opening is provided on the bottom surface of the moving area of the signature, and a sorting plate is provided which is vertically movable and which penetrates the opening from below the table when the upper end is raised and which vibrates.

In particular, the upper end of the shaft is rotatably supported, and the upper end thereof projects above the opening and is inserted between the signatures on the opening when rotated upward, and the sorting is performed without rotating upward. The effect is large when the rotating piece that covers the upper end of the plate is provided.

Further, it is pivotally supported by the lower ends of both ends of the opening so as to be rotatable, and the upper end does not project above the opening when the rotating plates face upward and are in contact with each other. The effect is large even if the rotating plate is provided so that the upper end thereof projects above the opening in the sandwiched state.

There are various types of signature transporting devices, but in general, there is a configuration in which side walls are provided on both sides in addition to the bottom surface so that a signature that is set up with the fold down will not come off. It is common. The bottom surface may be a simple bottom plate, but may be one provided with a conveyor such as a belt conveyor.

It is sufficient that the opening has such a shape that the sorting plate passes through and the signature does not fall. In the case of claim 2, it is necessary to pass the upper end of the rotating piece, and in the case of claim 3, the upper end of the rotating plate.

If the width of the sorting plate is too narrow, only the part corresponding to the sorting plate of the signature is likely to be applied, which causes defects in the signature. Conversely, if the width is too wide, the signature falls from the opening. Will end up.

The sorting plate may be vibrated at least when it is inserted between the signatures, but it may be structured such that it is constantly vibrated.

Although the movement of the rotating piece and the rotating plate may be controlled independently, a structure that moves according to the movement of the sorting plate can be easily created. A spring or the like can be used easily to position the rotating piece or the rotating plate when the sorting plate is located below the rotating piece or the rotating plate.

[0015]

In the apparatus of the present invention, when the signatures move in the thickness direction, the sorting plate is raised while vibrating finely so that a gap is smoothly formed between the signatures and the signatures are not damaged.

In the apparatus according to the second aspect, when the sorting plate is raised when the signature is moved in the thickness direction, the rotating piece is rotated so that the ridge line portion thereof projects from the opening, and the space between the signatures is increased. Form a gap. By doing this, the sorting plate will be removed from the rotating piece and inserted into the bundle of sorted signatures. The tip of the plate can be securely inserted into the signature, and the sorting plate can be advanced further up, and it is easy to sort without damaging the signature.

In the apparatus of claim 3, when the sorting plate is raised when the signature is moved in the thickness direction, the rotating plate is rotated so that its ridge line portion protrudes from the opening, and between the signatures. Form a gap. By doing this, the sorting plate comes off the rotating plate and is inserted into the bundle of sorted signatures, so the place where the sorting plate is placed between the signatures is widened, and the vibrating sorting is performed. The tip of the plate can be securely inserted into the signature, and the sorting plate can be advanced further up, and it is easy to sort without damaging the signature.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A sorting apparatus according to the present invention will be described with reference to the drawings. 3 and 4 are side cross-sectional views of the apparatus. The signature 11 with the fold side down on the table 10 is the support plate 1.
0a moves in the direction of the arrow, and the left support plate 1
When the passage of the sorting amount setting position P1 of 0a is detected, the motor 16 rotates to raise the slider 15 and the sorting plate 19
Is displaced upward.

FIGS. 5, 6 and 7 are front views of the opening 18. When the sorting plate 19 rises, the upper end portion 19a of the sorting plate 19 pushes up the inner side 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. To do. (See Figure 5)

This movement causes the upper end 19a of the partition plate to project from the opening 18 to the upper surface of the table 10. The upper end 21a of the rotating piece 21 has a sharp shape and enters between the folds of the signatures 11, 11 on the opening 18.
(See Figure 6)

Here, since the upper end portion 21a of the rotating piece 21 has an arc shape and rotates around the bolt 22, the sorted signatures are not damaged. Adjacent signatures 11, 1
Since the ridge line portions of the first fold line portion are sharpened by the pressing process, it is possible to reliably sort the adjacent signatures 11, 11 by rotating the rotating piece.

From this state, the slider 15 is raised to
When the sorting plate 19 is raised, the rotation center of the rotating piece 21 is displaced with respect to the protruding direction of the sorting plate 19, so that the rotating piece 21 rotates while being slidably contacted with the inner wall surface 21c of the sorting plate 19. It comes off after doing.

When the slider 15 is further raised after the sorting plate 19 is disengaged from the rotating piece, the sorting plate 19 enters between the signatures 11, 11 on the opening 18 and the signatures on the opening 18 are separated. 11 and 11 are separated. (See Figure 7)

FIG. 1 is a structural diagram of the partition plate 19. An electromagnet 26 is installed near the partition plate at the rear end of the iron partition plate 19 and is connected to an AC power supply 27.
The alternating current is half-wave rectified by the commutator 28 and a pulsed voltage is taken out. Since the electromagnet is intermittently turned on and off by this power source, the partition plate 19 is attracted to the electromagnet and vibrates in small steps. A variable resistor 29 and a damper 31 are provided to adjust the amplitude, and the amplitude is adjusted so that the signatures 11 and 11 can be inserted smoothly.

In the time required for the slider 15 to reach from the vicinity of the lower bearing 13 to the vicinity of the upper bearing 13, the moving amount of the signatures 11 ... Moving on the opening 18 of the table 10 is very small. Since the number is small, the sorting work by the sorting plate 19 is performed during the transportation of the signatures 11 ... On the table 10.

FIG. 2 is a structural diagram of a partition plate 19 of another embodiment. The structure is almost the same as that of the partition plate 19 described above, but a spring 32 is added to adjust the vibration.

In the time required for the slider 15 to reach from the vicinity of the lower bearing 13 to the vicinity of the upper bearing 13, the movement amount of the signatures 11 ... Moving on the opening 18 of the table 10 is very small. Since the number is small, the sorting work by the sorting plate 19 is performed during the transportation of the signatures 11 ... On the table 10.

Another sorting device will be described with reference to the drawings. Figure 8
Is a side sectional view of the apparatus. The signature 11 with the fold side down placed on the table 10 is moved in the direction of the arrow by the support plate 10a, and the passage of the sorting amount setting position P1 of the left support plate 10a is detected. Then, the motor 16 rotates to raise the slider 15 and displace the sorting plate 19 upward.

9, 10 and 11 are front views of the opening 18. When the sorting plate 19 is lifted, the upper end portion 19a of the sorting plate 19 is stuck between the rotating plates 34, and the rotating plate 34 is rotated in the direction in which it separates. (Refer to FIG. 9) The rotating plate 34 is provided on the frame 33 located below both ends of the opening 18.
It is rotatably supported by.

This movement causes the upper end 19a of the partition plate to project from the opening 18 to the upper surface of the table 10. The upper end portion 34a of the rotating plate 34 has a sharp shape and enters between the folds of the signatures 11, 11 on the opening 18.
(Refer to FIG. 10) Since the upper end portion 34a of the rotating plate 34 is sharpened, the opening of the rotating plate 34 allows the adjacent signatures 1 to be reliably joined.
1 and 11 can be sorted.

When the slider 15 is further raised after the sorting plates 19 separate the rotating plates 34 from each other, the sorting plates 19 are separated.
Enters between the signatures 11, 11 on the opening 18 and the signatures 11, 11 on the opening 18 are separated. (See FIG. 11) Since the structure of the partition plate 19 is the same in the following, the description thereof will be omitted.
