[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of automatically separating and replenishing a signature layer, which is capable of automatically separating and extracting a predetermined number of signature layers from the upper part of a signature layer that is vertically stacked. , And a signature separating and supplying device.

[0002]

2. Description of the Related Art In a device for handling a signature, such as a collator or a saddle stitcher, a predetermined amount is sequentially separated from the signature layers stacked vertically for stock and taken out at another place. Need to move to. As a typical example, there is a case where the accumulated signature layers are sequentially separated, taken out, and loaded on the signature table of the collator.

In this case, in the past, it relied on manpower,
From the viewpoint of labor saving, automation has been desired in separating and taking out from the signature layer.

[0004]

However, this automation has the following problems. First, in a collator, etc., a signature stand and a signature layer for sequentially supplying to the signature stand are prepared for each of a plurality of pieces of about 5 to 20, so when automating, It was desired that the signature separating and supplying method and device be inexpensive.

Further, in consideration of use in an automated bookbinding system for continuous automatic operation, separation of signature layers, a slight stop of take-out, or even a malfunction causes the entire system to stop. Replenishment method and equipment,
There was a demand for something that was reliable and without failure. The present invention is intended to solve the above problems, and a collator or the like that serves as an entrance to an automated bookbinding line makes it possible to inexpensively separate and take out a signature layer from a signature stand or the like. An object of the present invention is to provide a method for separating and replenishing a signature and a device for separating and replenishing a signature that can be automated and can be performed reliably and without failure.

[0006]

Means for Solving the Problems In claims 1 to 3,
As a method of separating and supplying a signature, claims 4 to 7 propose a signature separating and supplying device. The method for separating and replenishing a signature according to claim 1 is formed as a pointed tongue-shaped piece in a signature layer that is vertically stacked and accommodated in a stocker ,
An air jet with a diameter smaller than the tip thickness is applied to a certain point.
There is one hole in the center along the shape of the tip, both sides.
The separation claws formed in two places, a total of three places,
The horizontal compressed air from the air ejection hole in the center.
To form an inter-layer gap, and in that state the separation claw
Advance, insert the tip of the pointed portion into this interlayer gap,
At the same time, pressurized air from the air ejection holes on both sides of it
-It is formed so that the interlayer gap can be further expanded to both sides by
The separation claw in the gap between the layers
Further, insert the fork claw of the signature supply carriage at the same vertical position as the separation claw, and carry the signature layer separated by the separation claw on the signature supply carriage.
The feature is that the signatures accumulated and stored in the stocker are sequentially taken out from above.

Here, the signature layer means a layer in which the signatures are piled up and down, and the signature is a printed paper that is folded so that the printed contents are in the page order, and the final The folds are piled up and down so that the mountain side of the folds are horizontal, forming a signature layer. Usually, the mountain side of this final fold (below,
Say "Oriyama". ), The signature and the signature layer are separated and fed out.

The signature replenishing carriage is a transfer means for transferring the separated signature layers to another place, and the transfer method is not limited here. The fork claw is provided on the signature supply carriage, and does not interfere with the separation claw even when the fork claw is inserted in the interlayer gap formed by the separation claw at the same vertical position as the separation claw. It is provided in.

In this separation and replenishment method, pressurized air is blown to the folds of the signature layer to roll up the interlaminar gap between the folds and the folds, and the separation claw is inserted into the folded interlaminar gap. The signature layers are separated according to. When separating the signature layer by inserting the separation claw from the lateral direction into the signature layer thus accumulated, it is necessary to put the separation claw into the gap between the folded mountain and the folded mountain. , It was very difficult to accurately capture the gap between the layers. Even if we try to catch the space between the folded mountains by calculating from the signature thickness, the actual thickness was not constant and the exact position could not be grasped because the signature was folded.
Even if we tried to image the image of the folded mountain part of the origami layer and try to capture the space between the folded mountains, the image processing process was complicated, and we could not make something satisfactory in terms of time and cost. .

The present invention catches the fact that an appropriate interlayer gap already exists between the folded ridges of the signature layer, and pressurized air is blown to that portion so that the interlayer crevice is blown. This problem is solved inexpensively, automatically, and reliably and without failure by adopting a method in which the separation claw is inserted after the expansion. In other words, even if the position where the pressurized air is blown is slightly displaced from the gap between the folds and between the folds, and even if it is just above the folds, the folds can be broken by the pressurized air. From the relative relationship between the pressurized air and the fold mountain without damaging the claws, the fold mountain rolls up so that the fold mountain escapes with respect to the ejection direction of the pressurized air, centering on the position where the pressurized air is blown, An interlayer gap will be formed. After that, by inserting the separation claw from the same position as the spraying position,
The signature can be reliably inserted into the gap between the signature layers without damaging the signature. Also, such behavior
Since it is a series of simple operations such as the ejection of pressurized air and the insertion of the separating claw, it can be easily automated.

In this way, after the signature layers are separated by the separating claws, the separated signatures are sequentially inserted from above by inserting the fork claws of the signature supply carriage into the separated interlayer gaps. You can take it out. In the above description, the signature is described as a folded one, but in the case of so-called single signature, a paper without folds is a signature, but in principle, in that case as well, the invention of the present invention is used. The separate replenishment method is effective. Furthermore,
In this separation replenishment method, the shape of the separation claw is a pointed tongue.
Is formed on the tip of the tip, the thickness of the tip
Smaller diameter air ejection holes follow the shape of the tip.
There are 3 places, 1 place in the center and 2 places on both sides.
Identified, and correspondingly used
First, apply the horizontal direction from the air ejection hole in the center.
Form the inter-layer gap with compressed air and
Move the claws forward to insert the tip of the tip into this interlayer gap.
At the same time, and at the same time, add from the air ejection holes on both sides.
To expand the interlayer gap to both sides with compressed air
By forming it, the separation of the signature layer is further ensured.

Form the gap so that it expands to both sides, and
Insert the separation claw further into the gap between the layers , and
By lowering the base of the stocker by a predetermined amount downward, a separation gap is formed under the separation claw, and the fork claw of the signature supply carriage is inserted into the separation gap,
The signature layers separated by the separating claws are carried on the signature supply carriage, and the signatures accumulated and stored in the stocker are sequentially taken out from above.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. 1A to 1D are conceptual diagrams showing the procedure of the method for separating and replenishing a signature according to the present invention. In the figure, 1 is a stocker for accumulating and storing signature layers O in the vertical direction, 2 is a separation claw installed at a predetermined position above and below the stocker 1, and has air ejection holes 2a therein, which are not shown. The pressurized air is supplied from the pressurized air supply means, and the pressurized air is ejected from the ejection hole 2a. Reference numeral 3 denotes an air cinder, which receives the separation claw 2 installed on the head thereof from the pressurized air supply means (not shown) to supply the compressed air to the signature layer accumulated on the stocker 1 and horizontally Move back and forth in the direction.

Reference numeral 6 is a signature replenishing carriage, which is a transporting means for transporting the separated signature layer O to another location.
Reference character a is a fork claw provided on the lower portion thereof. Also,
In this figure, o is a signature that constitutes the signature layer O, oy
Is a fold mountain on the mountain side of the final fold of the signature, and A is an interlayer gap formed between the fold mountains oy of the accumulated signatures o.

The separating claw 2 is
The tip is installed so as to be close to the folded mountain oy side of the signature layer O accumulated in the stocker 1, and the compressed air is ejected horizontally from the air ejection hole 2a (Fig. 1). (A)). The pressurized air ejected from the ejection holes 2a forms a compressed air jet smaller than the interlayer gap A, and the pressurized air jet is the accumulated signature o.
If the jet flow is just the part of the interlaminar gap A between the folded mountains oy, the gap A is further rolled up, and the rolled up interlaminar gap A1 is removed. Formed and this jet does not damage the signature o at all.

Further, even if the jet flow is blown not just between the fold mountain oy but directly above the fold mountain oy, or if it is slightly deviated from the fold mountain oy, the jet of pressurized air and the fold mountain oy are generated. In view of the relative relationship between the two, the oriyama oy is rolled up by the pressurized air jet, and the rolled up interlaminar gap A1.
To form. Also in this case, the signature o is not damaged.

In this state, when the separation claw 2 is moved forward in the horizontal direction by the air cylinder 3, the separation claw 2 is just inserted into the formed inter-layer gap A1 (FIG. 1 (b)). In this way, the separating claw 2 can be inserted into the signature layer O and the signature layer O1 can be separated without damaging the signature o and without fail. Then, with the separation claw 2 inserted, by a base lifting means (not shown),
When the base (not shown) of the stocker 1 is lowered downward by a predetermined amount, only the signature layer O under the separating claws is deposited on the base, and the signature layer O is further lowered to the lower part of the separating claw 2. A separation gap A2, which is an enlarged gap, is formed (see FIG. 1).
(C)).

The fork claw 6a of the signature replenishing carriage 6 is inserted into the portion of the separation gap A2 thus formed, and the separated signature layer O1 is carried by the signature replenishing carriage 6 and is stored in the stocker 1. The folded and stacked signatures o can be sequentially taken out from above (FIG. 1 (d)). In this case, after the separation, the gap is further expanded to separate the separation gap A2.
After forming the fork, the fork claw 6 of the signature supply carriage 6
Since a is inserted, the control of the vertical position for inserting the fork claw 6a can be sufficiently performed even if it is rough, and the control is simplified.

However, even if such a separation gap A2 is not provided, the fork claw 6a of the signature supply carriage 6 is set in the same vertical position as the separation claw 2 and inserted in the state of FIG. 1 (b). It is not difficult to do. By doing so, the position control of the vertical position of the fork pawl 6a is somewhat
Although it is troublesome, the procedure for lowering the base can be omitted.

Further, this method is suitable for automation since it is constituted by the simple procedure of blowing pressurized air and inserting the separating claw as described above. FIG. 2 is a conceptual diagram of the state of FIG. 1D as seen from the direction of the arrow X in the figure. As you can see in this figure, the separation claw 2 and the air cylinder 3
Since the fork claws 6a of the signature supply carriage 6 have a shape that does not interfere with each other in the horizontal direction,
Even if the upper and lower positions are the same, they do not interfere with each operation. Next, a signature separating / supplying device that realizes the above-described signature separating / supplying method will be described.

FIG. 3 is a conceptual diagram showing the structure of an example of the signature separating and supplying device of the present invention. In the following description, the same parts as those in FIG. 1 will be assigned the same reference numerals and overlapping description will be omitted.
In the signature separating / supplying device 10 of the figure, 1 is a signature stocker corresponding to the stocker of FIG. 1, and 2 is a pointed tongue-shaped piece corresponding to the separating claw of FIG. 1, similar to the separating claw of FIG. It has an air injection hole 2a. Reference numeral 3 is an air cylinder that constitutes the pointed tongue-shaped piece driving means.

Reference numeral 4 is a base for constituting the signature stocker 1 and for depositing a signature layer thereon, which is moved up and down by a base elevating mechanism 5. The base raising / lowering mechanism 5 raises / lowers the base 4 by rotating a screw shaft with a motor.
2, a timing pulley 53, a timing belt 54, a timing pulley 55, a screw shaft 56, and a female screw 57.

As the motor 51, an ordinary electric motor or the like can be used, but if a servo motor is used, the base 4
It is possible to accurately control the elevation position of the. The base plate 52 fixes the position between the motor 51 and the screw shaft 56. The timing pulley 53 is fixed to the output shaft of the motor 51, and the timing pulley 55 is a screw shaft 56.
The timing pulley 53 and 55 are connected by the timing belt 54, so that the rotational force of the motor 51 is transmitted to the screw shaft 56.

One screw shaft 56 is erected on each side of the base 4 so as to sandwich the signature layers O deposited on the base 4 from both sides. Female screws 57 are fixed on both sides of the base 4 so as to be aligned with each other. Therefore, when the screw shafts 56 on both sides are synchronously rotated by the motor 51, the base 4 moves up and down according to the rotation of the screw shaft 56.

Although not shown, the screw shafts 5 on both sides are not shown.
In order to rotate 6 synchronously, motors may be provided respectively for synchronous rotation, or an appropriate intermediate pulley may be provided,
Two screw shaft side timing pulleys 55 fixed to the screw shafts 55 on both sides of one motor side timing pulley 53 may be connected by one timing belt 54 so as to rotate synchronously.

As is clear from the comparison between the signature separating / supplying device 10 and the procedure conceptual diagram of FIG. 1, the signature separating / supplying device 10 realizes the signature separating / supplying method described above. be able to. In addition, in this signature separating and replenishing device 10, if an appropriate lifting mechanism, for example, a lifting mechanism similar to the base lifting mechanism 5 is provided in the pointed tongue-shaped member driving means 3, the signature stocker 1 is moved forward. The vertical position at which the tongue-shaped piece 2 enters can be controlled arbitrarily, and when this is done, the pointed tongue-shaped piece 2 is placed at any vertical position and the signature layer O accumulated and stored in the signature stacker is stacked. As you enter the area
Can be separated by an arbitrary amount, and can cope with the case where the signature thickness changes.

Furthermore, according to the signature separating and replenishing device 10, the base lifting mechanism 5 can arbitrarily control the position of the base 4, so that the pointed tongue-shaped member driving means 3 is lifted. Even if the top and bottom position of the pointed tongue is not fixed and the position of the signature layer is moved up and down, the entry position of the pointed tongue can be relatively controlled, and the signature layer They can be separated in quantity and can accommodate changes in signature thickness.

FIG. 4 shows details of an example of the pointed tongue-shaped piece, (a) is a front view thereof, and (b) is a plan view thereof. The pointed tongue-shaped piece 2 has a tongue-shaped shape as a whole, and a tip portion thereof forms a pointed portion 2b, and inside thereof, a diameter smaller than the tip thickness of the pointed portion 2b. 3 air ejection holes 2a are formed.

When the pressurized air is blown onto the folded mountain of the signature layer by the pointed tongue-shaped piece 2, first, the pressurized jet air from the air ejection hole 2aa of the pointed portion 2b causes the width direction of the signature to be increased. An interlayer gap A1 (see FIG. 1) is formed in the central portion,
In that state, when the pointed tongue 2 is advanced, first, the pointed portion 2b is inserted into the interlayer gap A1 at the central portion, and at the same time, the air is blown out from the air blowout holes 2ab on both sides of the tipped portion 2b, so that the interlayer While the gap A1 is formed so as to further expand to both sides, the entire pointed tongue-shaped piece 2 is entirely covered with the interlayer gap A1.
Will be inserted into.

In this way, the signature layers can be separated more reliably and without failure. FIG. 5 is a schematic configuration diagram showing an example of a signature supply carriage used in the method for separating and supplying signatures according to the present invention. The signature supply carriage 6 is a transfer means for carrying the signature layer O1 (FIG. 1) separated from the signature layer O and transferring it to a necessary place.
Here, only the vertical transfer means will be described, but it is installed on the horizontal vertical and horizontal transfer means as a whole to transfer the carried signature layer O1 in the three axial directions of up, down, left and right. Is something that can be done.

The signature replenishing carriage 6 includes a motor 61 which is a driving device, a case 62 which fixedly supports the motor 61 and a ball screw spline shaft 68 which will be described later, and the motor 6.
1. The timing pulley 63 fixed to the output shaft of No. 1 and the ball screw nut 6 fitted onto the ball screw spline shaft 68.
7, a timing pulley 65 fixed to 7, a timing belt 64 connecting these two timing pulleys 63, 65 without phase shift, and a ball screw spline shaft 68 fitted externally to the spline groove of the ball screw spline shaft 68. Consists of a spline bearing 66 having a protrusion, a plate 69 fixed to the tip of a ball screw spline shaft 68, and two fork claws 6a protruding downward from the end of the plate 69 so as to form an L shape. Has been done.

The ball screw nut 67 and the spline bearing 66 are fixed to holes concentrically provided on the upper and lower sides of the case 62, and the ball screw nut 67 and the ball screw spline shaft 68 are fitted with the ball screw. Ball screw nut 6 without rotating
When only 7 is rotated, the ball screw spline shaft 68 moves up and down according to the rotating direction. The spline bearing 66 allows the ball screw spline shaft 68 to move up and down in the vertical direction, but the spline projections prevent the spline shaft 68 from rotating.

Therefore, in the signature replenishing carriage 6, when the motor 61 is rotated, the ball screw nut 67 rotates, and accordingly, the ball screw spline shaft 68 does not rotate but moves up and down. The claw 6a moves up and down. Further, as described above, the entire signature supply carriage 6, that is, the case 6
2 is installed in a horizontal moving means (not shown), and as a whole, the fork claw 6a can be freely moved in the up, down, left, right, front, and back directions.

Therefore, as described above, the signature layer O1 separated from the signature layer O can be carried, taken out, and transferred to a necessary place. FIG. 6 is a schematic configuration diagram showing another example of a signature supply carriage used in the method for separating and supplying signatures according to the present invention. This signature supply carriage 6
Compared to the signature supply carriage 6 of FIG. 5, A is only that the fork pawl portion is a fork pawl 6b having an air ejection hole 6ba therein similar to the separation pawl 2 described in FIG. Are different.

When the signature replenishing carriage 6A is used, the fork claw 6b also has the functions of the separation claw 2 and the air linder 3 described with reference to FIG. Therefore, it is not necessary to separately provide a separate claw on the stocker,
Cost reduction. The method / apparatus for separating and replenishing signatures of the present invention is for automatically replenishing signatures on a signature stand for accumulating a certain number of signatures in order to feed the signatures one by one. Therefore, it is applicable to all collating machines regardless of the method of feeding the signature from the signature stand. For example, not only the vise type but also the rotary type is applicable.

Further, not only the collating machine but also the saddle stitching machine for collating and saddle-stitching the signatures, since the same signature stand as the collating machine is used, It is possible to apply the separate replenishment method and device.
