The present invention relates to a book collecting device.

[0002]

2. Description of the Related Art A stacker bundler is used to carry a stencil that is sequentially discharged in a scaly shape by a conveyor or other transporting device, stack the slivers that are carried in, accumulate the stencils, bundle them into a predetermined number of stencils, and carry them out. For example, there is a mechanism as shown in FIG. In FIG. 7, the stacker bundler S
Is connected and installed on the discharge side of the rotary press P by a transport device Q such as a conveyor, and on the discharge side of the stacker bundler S, there is further provided a transport device for unloading the signature stack such as a conveyor.

The stacker bundler S is composed of a small bundle forming section X, a large bundle forming section Y, and a binding section Z which are successively connected to a conveying device Q such as a conveyor from the discharge side of the rotary press P. Is followed by a signature stack unloading transport device. The small bundle forming unit X is provided at the discharge end of the transport device Q, at a position appropriately below the transport surface of the transport device Q, at the receiving plate 2 that moves forward and backward, at the receiving position immediately below the receiving plate 2 at the advanced position, and at the lower position. The lifting table 3 is moved up and down between the horizontal feeding positions, and the pusher 4 is in an upright posture that moves up and down on the lifting table 3 at the lowered position.

[0004] The large bundle creating section Y is located at a side of the lifting table 3 of the small bundle creating section X, and has a rotatable turntable 5 having a central portion formed by a vertically movable lifting plate 5a.
A lifter L comprising a fluid pressure cylinder 7 for raising and lowering the lifting plate 5a and a rotating member 6 for rotating the turntable 5, and an upper and lower position above the turntable 5 for accommodating a plurality of small bundles 1, ie, large bundles 12. A large bundle accumulating means 10 comprising a fork claw portion 11 which moves forward and backward with respect to the hollow body at the lower end of the hollow body and the hollow body which escapes in the direction.

[0005] The signature R discharged from the rotary press P is conveyed by a conveying device Q such as a conveyor, and sequentially discharged onto the receiving plate 2 of the small bundle forming section X of the stacker bundler S.
Stacked. When a certain number of signatures R are stacked,
The receiving plate 2 retreats. Then, the stacking portion falls on the elevating table 3 at the receiving position, and further the elevating table 3
When the number of the signatures R is stacked to form the small bundle 1, the release of the signatures R is temporarily stopped by a stopper (not shown), and the receiving plate 2 moves forward to advance the next signature R.
The elevating table 3 moves down to the traversing position while preparing for the discharge.

Subsequently, the pusher 4 advances, and pushes the small bundle 1 on the elevating table 3 onto the turntable 5 at the receiving position at the same height as the elevating table 3 at the lateral feed position. During this time, the stop of the signatures R by the stopper (not shown) is released, and the signatures R are sequentially discharged onto the receiving plate 2 and stacked. Then, the lifting plate 5a forming the central portion of the turntable 5 is raised by the operation of the fluid pressure cylinder 7, and the small bundle 1 transferred onto the turntable 5 is closed by the fork claw of the large bundle accumulating means 10. Push up toward part 11.

Prior to pushing up the small bundle 1, the fold of the signature of the small bundle 1 to be pushed up is opposite to the fold of the signature of the preceding small bundle 1 at the bottom of the large bundle accumulating means 10. The turntable 5 rotates with the rotating member 6 so as to be on the side. As a result, in the large bundle accumulating means 10, the fold of the signature of the preceding small bundle 1 and the fold of the signature of the subsequent small bundle 1 are on the opposite sides, and the folds of the small bundle accumulated in the large bundle are alternately formed. As a result, the large bundle is balanced in the thickness direction, and the large bundle is stabilized.

When the upper surface of the small bundle 1 reaches a predetermined height, the fork claw 11 is opened in the left-right direction, and the large bundle 12 already placed on the fork claw 11 is slightly dropped, so that the small bundle Stack on Bundle 1. The elevating plate 5 continues to rise during this time, and stops slightly above the fork claw 11. Then, the fork claw 11 is closed and enters under the lifting plate 5.

At this time, the claw of the fork claw portion 11 is positioned in alignment with the notch position of the elevating plate 5. continue,
When the lifting plate 5a is lowered, the small bundle 1 and the large bundle 12 stacked on the lifting plate 5a
Delivered on one. Further, the lifting plate 5a descends to substantially the same level as the turntable 5, rotates together with the turntable 5, returns to the standby position, and stands by.

By repeating the above-described operation, a certain number of small bundles are accumulated in the large bundle accumulating means 10, and a large bundle 12 is created. Then, the large bundle accumulating means 10
Sends the large bundle 12 to the binding portion Z. The large bundle 12 has a binding portion Z
The band is united to form a signature stack 13,
The signature stack is transported out of the machine by the transport device.
In the configuration of the stacker bundler described above, the lift plate of the turntable device of the large bundle forming unit that can be moved up and down is, for example, disclosed in Japanese Unexamined Patent Publication No. Hei.
No. 16 and JP-A-5-92553.

[0011] Japanese Unexamined Patent Publication No. 4-253616 discloses that a small table is placed on a turntable and a plate that rises is capable of performing signature processing of a plurality of sizes, for example, A4 size and A5 size. The size and notch shape are the same, and even if the size of the signature carried out from the rotary press is changed, it is a multi-purpose type that does not change the plate.

[0012] Further, in the apparatus described in Japanese Patent Application Laid-Open No. 5-92553, a plate having a size and a notch shape corresponding to a small-sized signature is always attached, so that a large-size signature can be used. During processing, an auxiliary plate for forming a size and a cutout shape corresponding to a large size is manually engaged with a small size plate and used each time.

[0013]

In the prior art described in Japanese Patent Application Laid-Open No. Hei 4-253616, the lifting plate is of an integral type corresponding to the size of a large / small signature. When transferring the placed bundle to the large bundle stacking means, the large bundles are stacked in the narrow direction of the lifting plate, and the small bundles are stacked in the wide direction of the lifting plate, respectively. The fork is rotated on the turntable in advance so that the fork claw enters.

For this reason, the lifting plate must be provided with a common notch so that the fork claw can be inserted from two directions, that is, the narrow direction and the wide direction, and as a result, the notch portion needs to be considerably large. There is. Therefore, when a large-size signature bundle is lifted by the lifting plate, the signature on the lower side of the signature bundle hangs at the notch portion of the lifting plate, and the whole bundle becomes poorly packed and the stability is impaired. Then, the delivery to the large bundle accumulating means causes a problem that the hanging portion of the signature, particularly the four corners, is bent by the fork claw portion.

Further, the fork claw portion needs to be longer in order to be able to enter from the wide direction of the elevating plate and to take out a bundle of small-sized signatures. The device becomes thick and large, and the device must be enlarged by the length of the nail.

The above prior art is disclosed in Japanese Patent Application Laid-Open No. 5-92553.
In the publication described in the above publication, every time the signature size is changed, the lifting plate of the turntable must be manually changed to a plate corresponding to the signature, which imposes a heavy burden on the operator. Also, when processing small-sized signatures, the portion of the turntable surface from which the auxiliary plate has been removed remains missing, and the turntable must be used in an extremely unstable state. An object of the present invention is to solve the above-mentioned problems in the conventional technology.

[0017]

SUMMARY OF THE INVENTION In a signature stacking apparatus according to the present invention comprising a lifter and a signature stacking means provided above the lifter, the lifter has a central portion rotatable about a vertical axis. A first signature bundle support portion, a second signature bundle support portion located in an outer region thereof and rotatable together with the first signature bundle support portion, a first signature bundle support portion and a second signature bundle A driving device for rotating the support portion forward or backward by a predetermined rotation angle about the longitudinal axis, and a first signature bundle support portion and a second signature bundle support portion engageable and disengageable with respect to at least vertical movement. Engaging means for performing
Lifting means for lifting and lowering the signature bundle support portion,

The signature stack accumulating means includes a stacking space portion for accommodating a plurality of signature stacks, which is drawn downward, and a signature stack supporting member which moves forward and backward with respect to the stacking space at the lower end of the stacking space portion. The predetermined rotation angle is an angle at which the signature of the preceding signature bundle and the signature of the subsequent signature bundle are on opposite sides,
The retracted retraction position of the signature bundle support member is a position at which the signature bundle support member allows the signature bundle to pass upward, and the forwardly projecting position of the signature bundle support member is such that the signature bundle support member is located within the accumulation space. The position where the signature bundle is supported, and the concave contour shapes of the first signature bundle support portion and the second signature bundle support portion at a predetermined rotation angle position and the projection contour shape of the signature bundle support member at the forward projecting position Are formed in such a way as to allow the first and second signature bundle support portions to pass up and down with respect to the signature bundle support member at the forward projecting position.

[0019]

The operation of the signature stacking device having the above-mentioned lifter and signature stacking means is as follows. In the case of processing a small bundle of large format signatures, first, the signatures discharged from the rotary press are converted into signature small bundles and loaded onto the first signature bundle support portion and the second signature bundle support portion. Is done.

Therefore, the first signature sheet bundle supporter and the second signature sheet bundle supporter are rotated by a predetermined angle as required by the driving means. As a result, the signature of the signature small bundle placed on the first signature bundle support portion and the second signature bundle support portion is pushed forward by the stacking space portion and stored earlier. The direction is opposite to the folding line of the book bundle. Since the first signature bundle support portion and the second signature bundle support portion are engaged with at least the vertical movement by the engagement means, the first signature bundle support portion is raised by the elevating means. Also, the second signature sheet bundle support portion also rises integrally toward the accumulation space portion.

Therefore, the small signature bundle whose signature is folded in the opposite direction to the preceding small signature bundle is supported by the first signature bundle support portion and the second signature bundle support portion and rises. When reaching directly below the signature bundle support member supporting the signature small bundle of from below, the signature bundle support member retreats to the retracted retraction position at its tip,
Since the small signature bundle is allowed to pass through, the small signature bundle accumulated together with the preceding small signature bundle slightly falls and is folded on the first signature bundle support portion and the second signature bundle support portion. It is placed on the book bundle.
Then, the first signature sheet bundle support portion / the second signature sheet bundle support portion places the preceding signature sheet bundle and the accumulated signature sheet bundle on the signature sheet bundle, and places them in the accumulation space. Is further raised above the signature bundle support member.

Then, the signature bundle support member protrudes forward and enters the lower side of the first signature bundle support portion and the second signature bundle support portion to be in the forward projection position. Similarly, the first signature bundle support portion and the second signature bundle support portion descend integrally. At this time, the first and second signature sheet bundle support portions having contour shapes that can pass through the signature sheet bundle support member at the forward projecting position pass through the signature sheet bundle supporting member at the forward projecting position. The signature small bundle is left on the signature bundle support member at the forwardly projecting position, and is supported by the stacked signature small bundle together with the stacked signature small bundle below the preceding signature small bundle.

[0023] When the small signature bundle is rotated to a predetermined position where the signature bundle is carried in and then rotated, the first signature bundle support portion and the second signature bundle support portion are driven by the driving means. Conversely, it rotates by a predetermined angle and returns to the original position. By repeating such operations a predetermined number of times, a predetermined number of small signature bundles having alternately folded signatures are accumulated in the stacking space, thereby forming a large signature large bundle.

Next, in the case of the small signature sheet of the small signature sheet, the small signature sheet is carried on the first signature bundle support portion, and is first accumulated in the same manner as in the case of the large signature sheet. It is in the opposite direction to the signature of the preceding signature small bundle pushed up and stored in the space. The engagement between the first signature bundle support portion and the second signature bundle support portion by the engagement means is disengaged. Therefore, even if the first signature sheet bundle support portion is raised toward the accumulation space by the lifting / lowering means, the second signature sheet bundle support portion is not lifted but remains.

Therefore, the small signature bundle with the reverse signature and the signature folded in the opposite direction rises while being supported by the first signature bundle support portion. When reaching directly below the supporting signature sheet bundle supporting member, the tip of the signature sheet bundle supporting member retreats to the retracted retraction position, and allows passage of the signature sheet bundle. The small signature bundle accumulated together with the small signatures falls slightly and is placed on the small signature bundle on the first signature support portion.

Then, the first signature supporter places the leading signature small bundle and the stacked signature small bundle on the signature small bundle, and moves through the accumulation space from the signature support member. Further rise until it is up. Next, the signature support member protrudes forward, and the first
Following the entry into the lower side of the signature support, the first projection support descends in the same manner as when ascending by operating the elevating means.

At this time, the first signature support portion having a contour shape capable of passing through the signature support member at the forward projecting position passes through the signature support member at the forward projecting position. It is left on the signature support member at the position, and is supported by the signature support member together with the accumulated signature small bundle under the preceding signature bundle.
Then, after being lowered to a predetermined position where the signature sheet bundle is carried in, if it is rotated first, the first signature support portion and the second signature member are
The signature holder is rotated by a predetermined angle by the driving means and returns to the standby position. Thus, a large bundle of small-sized signatures is formed in the same manner as the large bundle of signatures.

It is set at the same interval position and carry-in direction position as the second side plates 9a, 9a corresponding to the size of the small bundle 1, and is at the open position.

Then, the pusher 4 advances, and the small bundle 1 on the elevating table 3 is pushed out onto the connection table T, and further guided by the second side plates 9a, 9a and the gate plates 9b, 9b to be coplanar. The small bundle 1 is pushed out onto the turntable 5 at a certain lowering position, that is, the receiving position, and the leading edge of the small bundle 1 abuts on the first side plate 8. The first side plate 8 is set such that the small bundle 1 when the leading edge abuts on the first side plate 8 is located at the center position of the turntable 5. Then, the gate plates 9b, 9b rotate 90 degrees to the closed position. Therefore,
The small bundle 1 is held from all sides by the first side plate 8, the second side plates 9a, 9a and the gate plates 9b, 9b so as not to collapse at the center position of the turntable 5.

First, a case of processing a small bundle 1a of large-format signatures will be described. Transported by the transport device Q,
The central part of the turntable 5, that is, the small size plate 20
-The small bundle 1a of large format origami carried on the auxiliary plates 21 and 21 has the fold facing forward and the dimension in the width direction is larger. (See FIG. 4) Then, the rotating member 6 is driven by driving means as shown in FIG.
Rotate 0 degrees. The rotation direction is such that the folding line of the preceding small bundle 1a is opposite to the folding line of the small bundle 1a on the turntable 5, that is, the rotation when the preceding small bundle 1a is handled. The direction is opposite to the direction. Then, the turntable 5 connected to the rotating member 6 also integrally moves in the same direction 9.
Rotate 0 degrees.

The auxiliary plate 21 also rotates 90 degrees in the same direction integrally via the bracket 32, the fluid pressure cylinder 30, the piston rod 30a, the fork-shaped portion 28, the gripping claw block 27, the block 24 and the block 23. At the same time, since the gripping claw block 27 released by the hydraulic cylinder 30 at the forward position also grips the block 22 with the spring force of the compression coil spring 26, the small-size plate 20 is also connected to the hydraulic cylinder The rotatable block 22, that is, the small size plate 20, is also rotated by 90 degrees in the same direction with the auxiliary plate 21 in the piston rod 7 in the same direction.

Therefore, the small bundle 1a on the small size plate 20 and the auxiliary plates 21 and 21 is rotated by 90 degrees so that the direction of the fold signature is opposite to that of the preceding small bundle 1a. Then, the origami fold becomes horizontal with a narrow width. (FIG. 5
(See (A).) Then, the hydraulic cylinder 7 is operated and the piston rod projects upward, and the block 22, that is, the small
Rises. At this time, the block 23 connected to the block 22 by the engaging / holding means, that is, the auxiliary plate 21 also rises integrally with the small size plate 20. At this time, the fork-like portion 28 is separated upward from the piston rod 30 of the fluid pressure cylinder 30.

Therefore, the small bundle 1a having the reverse folding direction with the preceding small bundle 1a rises while being supported by the small size plate 20 and the auxiliary plates 21 and 21. When the fork pawls 11, 11 reach just below the supporting fork pawls 11, 11, the fork pawls 11, 11 recede to a release position where their tips are separated by more than the narrow width of the small bundle 1a. Is allowed, so the preceding small bundle 1a, ...
Is slightly dropped and placed on the small bundle 1a on the small size plate 20 and the auxiliary plates 21 and 21. And the small size plate 20 and the auxiliary plates 21 and 21
Are further elevated in the stacking space 60 until they are above the fork claws 11, 11 while the preceding small bundles 1a,.

Then, the fork claws 11, 11 move forward to face each other, and the small-size plate 20 and the auxiliary plates 21, 21 are moved.
Into the closed position, and then the hydraulic cylinder 7 is operated to retract the piston rod downward, and the auxiliary plate 21 and the small-sized plate 20 are integrally formed with the turntable 5 in the same manner as when the piston rod is raised. The fork 28 is engaged with the piston rod 30a of the fluid pressure cylinder 30 from above until it is lowered to the same plane.

At this time, the fork claws 11, 1 in the closed position
The small-sized plate 20 and the auxiliary plates 21 and 21 having a contour that can pass between the fork claw portions 11 and 21 in the closed position.
, The small bundle 1a is left on the fork claw portions 11, 11 in the closed position, and the small bundles 1a,. It is supported by the claws 11, 11.

Then, the rotating member 6 is rotated 90 degrees in reverse by the driving means as shown in FIG. 6 to return to the standby position (FIG. 4). Turntable 5 and auxiliary plates 21 and 21 and auxiliary plates 21 and 21 connected to rotating member 6
The small-sized plate 20 coupled to the first position is integrally rotated by 90 degrees in the same direction and returns to the standby position (FIG. 4). By repeating such an operation a predetermined number of times, a predetermined number of small bundles 1a having alternately folded folds are accumulated in the accumulation space 60, and a large bundle 12 is formed.

Next, the case of processing a small bundle 1b of oval origami will be described. The small bundle 1b of small-sized signatures transported by the transport device Q and carried on the center of the turntable 5, that is, loaded on the small-sized plate 20, is further folded by the small bundle 1a of large-format signatures, and the folds are in the horizontal direction. The dimensions in the direction and width direction are smaller. (See FIG. 5B)

Therefore, when the signature of the preceding small bundle 1b already stored at the lowermost side of the large bundle accumulating means 10 and the signature of the small bundle 1b on the small size plate 20 are in opposite directions, ,
The turntable 5 is not rotated, but the preceding small bundle 1
In the case where the fold book fold b and the fold book fold of the small bundle 1b on the small size plate 20 are in the same direction, the turntable 5 is rotated by 180 degrees. In other words, the turntable 5 is rotated by 180 degrees every other small bundle transfer. That is, when the rotation is performed, when the rotating member 6 is rotated by 180 degrees by the driving unit as shown in FIG. 6, the turntable 5 connected to the rotating member 6 is also integrally rotated by 180 degrees.

The auxiliary plate 21 also rotates integrally by 180 degrees via the bracket 32, the fluid pressure cylinder 30, the piston rod 30a, the fork-like portion 28, the gripping claw block 27, the block 24 and the block 23, and
The small-sized plate 20 also holds the block 22 with the spring force of the compression coil springs 26, 26 because the gripping claw blocks 27, 27 released by the hydraulic cylinder 30 in the forward position grip the block 22. Pressure cylinder 7
The rotatable block 22, that is, the small-sized plate 20, also rotates 180 degrees integrally with the auxiliary plate 21 on the piston rod. Therefore, the small bundle 1b on the small size plate 20
Rotates 180 degrees and the direction of the origami fold is
It is the opposite of the direction of the fold book fold of b.

[0077]

According to the signature stacking and stacking apparatus of the present invention including the lifter and the signature stacking means provided above the lifter, the signature stacking device corresponding to the size of the signature transported by the rotary press is provided. It is provided with a large-sized signature bundle support unit, which is a combination of the first signature bundle support unit and the second signature bundle support unit, and an oval signature bundle support unit consisting of only the first signature bundle support unit. Since the signature support and the oval signature support can be automatically selected, each time the size of the signature changes, the operator changes the signature bundle support of the lift according to the signature size of the signature bundle. This eliminates the need for mounting, and can save labor.

Further, the signature bundle support portion of the lift is provided on the inner first
It is composed of a signature bundle support portion and an outer second signature bundle support portion. In the case of an oval signature, the first signature bundle support portion moves up and down independently. Since the support portion and the second signature sheet bundle support portion are adapted to move up and down, the first
The signature bundle support portion and the second signature bundle support portion may be formed with their own concave and concave contour shapes corresponding to the protruding contour shapes of the signature bundle support member of the signature bundle stacking means.

That is, the concave notch portions of these contour shapes are shared in two directions of the narrow width direction and the wide width direction in a type in which a single elevating plate is used for both large and small signature sizes and rotated and used. It is not necessary to increase the size of the folded booklet as in the case of the concave notch. Therefore, even when a large-sized signature bundle is supported by the first signature bundle support portion and the second signature bundle support portion, the lower side of the signature bundle is folded. The book does not hang down in the concave notch, and the packing of the whole bundle does not deteriorate, and the stability is not impaired.

Further, the projecting portion of the projected contour shape of the signature bundle support member of the signature bundle stacking means can be used for both the large signature bundle and the small signature bundle in the first signature bundle. Since the signature bundle is drawn into the support portion or the second signature bundle support portion from the narrow width direction and is taken out, the protrusion length does not increase. Therefore, the apparatus is compact, and the supporting strength for the signature stack is maintained without increasing the thickness of the protrusion.
