Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a method for stacking a certain number of small bundles of signatures in a required number of stages and binding them with bands. In particular, a stacker for stacking signatures into small bundles of a certain number of copies, and a stacking machine for stacking the small bundles of signatures from the stacker into a certain number of tiers. This invention relates to a signature binding pre-processing device in which machines are installed side by side and a transfer means using an elevator and a turntable is added to the equipment.

In this type of signature bundling preprocessing device, the elevator is used to carry out vertical feeding in the process of transferring the small bundle of signatures from the accumulator to the stacker.

On the other hand, the reason why the above turntable is applied is as follows.

The folding side has a larger thickness collected from the cut end side on the opposite side, and it becomes unstable if you accumulate only the same direction and stack many steps in the cotton small bundle. When stacking the stacks, it is necessary to horizontally turn the small bundles of signatures one after another in the stacking order so that the folds occupy the opposite sides. It is included as a component of

This type of signature binding pre-processing device applies the specifications of an elevator and a turntable to transfer the signature bundle stack from the stacker to the stacker, so that the vertical feeding and orientation of the signature bundle stack is controlled. Advantageously, inversion can be performed with a small footprint.

BACKGROUND TECHNOLOGY Conventionally, this type of fold binding preprocessing device has a structure in which a turntable also serves as an elevator, and the turntable and elevator is disposed below a stacking machine. Showa 59
-128158) is known. As a specification for rotating the turntable, a reversal and return type is disclosed in which a rod driven by an air cylinder moves back and forth. This conventional technique has the following problems.

In the above-mentioned type of preprocessing device, the process of transferring a small bundle of signatures (herein abbreviated as a small bundle) from the stacker to the stacker consists of the first step of receiving the small bundle, lateral feeding (processing on the stacker side) ) and the second stack of small bundles.
process (processing on the stacking machine side).

In the above-mentioned conventional technology, the first step includes lowering the elevator (turntable) that received the small bundle (adjusting the height of the small bundle to the upper feed level for the stacker), reversing the lowered turntable,
There are 6 operations: forward movement of the small bundle cross-feeding pusher, retraction of the same pusher, return rotation of the turntable, and raising of the elevator (turntable).The second step is the raising of the upper feed plate (small bundle stacking).
and lowering (returning) the upper feed plate. In other words, there is a large difference in the number of operation steps between the two processes, such as 6 operations in the first process, which is the preceding process, and 2 operations, in the second process, which is the subsequent process, so the operation of the first process on the second process side is completed. There is a lot of time lost due to waiting, and high efficiency cannot be expected.

Furthermore, there is also known a system in which a turntable is disposed below the stacking machine and an elevator is disposed below the stacking machine (Japanese Patent Application Laid-open No. 82818/1983).

In this conventional technology, the turntable is in charge of the first process, the elevator is in charge of the second process, and the processes of unloading, reversing, cross-feeding, and top-feeding necessary to transfer small bundles from the stacker to the stacker. It is essential to perform the procedures in the same order. This means that the unloading process and the reversing process are inseparably attached to each other, and cannot be performed simultaneously in order to improve efficiency. That is, this conventional technique cannot provide high mechanical efficiency.

An object of the present invention is to solve the problems caused by the above-mentioned prior art, and to efficiently transfer small bundles of signatures from a stacker to a stacker in a signature bundling preprocessing device of the type mentioned at the beginning, compared to the prior art. In order to obtain high mechanical efficiency, it is also possible to obtain high mechanical efficiency.

Means for Solving the Problems An apparatus according to the present invention includes a stacker for stacking signatures into small bundles of a certain number of copies, and a stacking machine for stacking the small bundles of signatures from the stacker into a certain number of stages. In the signature bundling preprocessing device in which stacking machines are installed side by side, the elevator is used to unload the stack of small bundles of signatures from the stacking machines and send them to the side of the stacking machine by a cross-feeding means. A turntable disposed below the accumulator, having upward feeding means for sending the small bundle of signatures upwards, and capable of angular displacement of 180° and 90° in directions around the vertical axis, is arranged in the elevator. It is characterized in that it is disposed adjacent to and below the stacking machine.

In the present invention, the turntable disposed below the stacking machine is placed adjacent to the elevator below the stacking machine because it is necessary for the transverse feeding means to transversely feed the small bundle of signatures.

In the present invention, conventionally known devices may be used as the stacker for small bundles of signatures, the cross-feeding means, and the stacker for stacking small bundles of signatures.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

The turntable 1 is separate from the elevator 202 that faces below the shelf 201 of the folded small bundle stacker 2 that can be retracted to the left in FIG. The turntable 1 is mounted on the elevator 202 on the side where the later-described stack of signatures on the elevator 202 is pushed away by a pusher 42 of a hydraulic cylinder plunger device 41, which is per se conventionally known fixed position traversing means. It is arranged at a position adjacent to and facing below the folding stacker 3. The signature bundle stacker 2 and the signature bundle stacker 3 are shown schematically in FIG.

In addition, the elevator 202 is connected to the small fold stacking machine 2.
The elevator 20 is in a state where it has received a small bundle of signatures, which will be described later, and has been raised to a fixed position.
The pusher 42 has a framework structure having an internal space 202c such that the pusher 42 can retreat from the forward position without touching the elevator 202. The elevator 202 is a fluid pressure cylinder/plunger device 2 that moves the top plate 202a up and down.

In FIG. 1, the signatures a are indicated by the reference numeral a, and the signatures a are successively discharged from a previous process such as a rotary press (not shown) to the starting end of the belt conveyor 39 in the state shown in FIG. After being sorted into small bundles for a predetermined number of copies according to a conventionally known method, the belt conveyor 40
The predetermined number of small bundles of signatures are moved to a shelf 20 that can be retracted in a predetermined direction in the small bundle stacker 2.
1, that is, received.

After receiving the small bundle a' of signatures a... accumulated on the shelf 201,
By retracting the shelf 201 to the left in FIG. 1, it is lowered onto the elevator 202 in the fixed position. At this time, the elevator 202 has ascended to a predetermined height before the shelf 201 moves back.

After receiving the stack of signatures a', the elevator 202 descends to the solid line position in FIG. 1 and stops there.

Then, the signature bundle a' on the elevator 202 is transferred to the hydraulic cylinder plunger device 41.
Lateral feeding by the pusher 42, that is, feeding to the turntable 1, which will be described later, is performed.

After this feeding, the shelf body 201, the elevator 2
02 and pusher 42 return to the initial standby position.

The above-mentioned signature bundle sorting process and signature bundle stacking process for a predetermined number of copies are repeatedly performed.

The turntable 1 is of a reversible type and is rotated by a motor 4 with a brake through transmission gears 5 and 6. Gear 5 is shaft 7 of motor 4
A gear 6 is fixed to the turntable 1, and a drive gear 9 of a cam type switch 8 is meshed with the gear 5. The switch 8 includes a first switch (not shown) that is switched on at the rotational speed or rotational phase of the gear 9 corresponding to the end of the 180° rotation of the turntable 1, and a first switch (not shown) that is switched on at the rotational speed or rotational phase of the gear 9 corresponding to the end of the 90° rotation of the turntable 1. It has a second switch (not shown) that is switched on at the rotational speed or rotational phase of the gear 9 corresponding to A signal is input to the inverter 10, and the frequency from the inverter 10 is converted into a frequency that immediately responds to switching the rotation of the motor 4 to a rotation speed as slow as possible from the previously steady rated rotation speed. When the motor 4 switches to low speed rotation and the turntable 1 reaches 180° rotation or 90° rotation,
The current to the motor 4 is cut off, and at the same time, the brake of the motor 4 is activated, so that the motor 4, in other words, the turntable 1, is stopped at a fixed position.

The 180° rotation of the turntable 1 corresponds to a certain dimension, for example, horizontal rotation reversal of the signature number 5 in the JisB row.
The 90° rotation can also be applied to certain other dimensions, such as the horizontal rotational reversal of the signature in row 4 of JisB. When applying to 180° angle reversal, the second switch of switch 8
When applying to 90° angle reversal without closing the circuit belonging to the switch 8,
All you have to do is keep the open/close switch from working. When reversing a signature by 90 degrees, the rotation of the motor 4 is controlled so that the turntable 1 is alternately displaced by 90 degrees on both the left and right sides (both clockwise and counterclockwise in FIG. 4). When reversing a signature by 180 degrees, the rotation direction of the turntable 1 may be any one direction.

The turntable 1 is equipped with fences 11 at positions corresponding to the four vertical ridge lines of the collection of small bundles of signatures received by the table 1, which will be described later. A fence 12 is placed at a corresponding location between the fences 11 and the fences 11. Each of the fences 11, 11, 11, 11 can be pivoted to open and close in directions around a vertical axis.

The fences 11 arranged in the horizontal direction in FIG. 4 and the fences 12 between the fences 11 are also moved back and forth with respect to the turntable 1 along the vertical direction in FIG.
It is preferable that these fences 11 and 12 move in a unitary manner in a pair of fences 11 and 12 arranged in parallel along the direction A. The figure shows such an integrally movable type, in which support plates 19, 19, which are provided on the turntable 1 and which face each other in the vertical direction in FIG. Equipped with a set of 20 is Fuens 12
The mounting bracket is shown. The support plate 1
9 and 19 are feed screw rods 21, 21 that are parallel to each other in the left-right direction in FIG. 4 and extend in the vertical direction in FIG.

The feed screw rods 21, 21 are mounted on a frame 23 fixed to the turntable 1. The feed screw rods 21, 21 are connected by a chain sprocket transmission mechanism 24, and one feed screw rod has a handle 25.

The feed screw rods 21, 21 are operated by the handle 25.
When the support plates 19, 19 are rotated forward and backward, the support plates 19, 19 are moved forward and backward along their opposing directions (up and down directions in FIG. 4), and accordingly, the upper and lower sets of fences, 11, 11, 12, 12 are moved in the same direction. Fences 11, 11, 1 are shown in the upper half of Figure 4.
2 and 12 are shown occupying the positions corresponding to the 5-size signature in the JisB row, and in the lower half of Fig. 4, the fences 11, 11, 12, and 12 correspond to the 4th signature in the JisB row. It is shown in position.
Fens 11, 11, 12, 12 and 12,
12 is installed on the turntable 1, so it rotates together with the turntable 1 when it rotates.

26 and 27 are upper feeding plates as upward feeding means for the signatures. The upper feeding plate 26 is for the signature in the JisB row No. 4 and is on the lower half side of Fig. 4, and the upper feeding plate 27 is for the signature in the JisB row No. 5. It is for signatures and is shown in the upper half of FIG. The upper feed plates 26 and 27 are selected and attached to the plunger 28a of the vertical hydraulic cylinder plunger device 28. The plunger 28a is vertically slidable relative to the gear 6 fixed to the turntable 1, but is coupled to drive rotation. The upper feed plate 26, 2
7 is configured to be vertically movable in a space 29 passing through the top and bottom of the turntable 1 when attached to the plunger 28a, and to be fitted so that the top surface of the turntable 1 and the top surface are flush with each other.

30, the opening/closing mechanism 1 of the fence 11 is attached to the support plate 19;

This is a groove that penetrates vertically. The groove 30 is connected to the opening/closing mechanism 1
3 on the fence 12, in other words, the opening/closing mechanism 13 may be omitted if it occupies a position above the turntable 1.

When the turntable 1 is equipped with the groove 30, when the signature is fed into the turntable 1 in the direction of the arrow A, which will be described later, the tip of the signature passes through the groove 30 without being caught in the groove 30. In order to ensure this, it is preferable that the portion along the groove 30 on the side opposite to the center of the turntable 1 be formed into a slope 31 that slopes highly from the opposite side to the center side.

Each of the above parts is mounted on a frame 32. The frame 32 is configured to move back and forth in a direction perpendicular to the signature receiving direction A, as required. Its longitudinal movement structure is shown in FIG. In addition,
In FIG. 11, the turntable 1 is schematically shown as a disk.

Reference numeral 34 indicates a groove-shaped sliding plate attached to the frame 32, 35 indicates a wheel provided on the frame 32, the sliding plate 34 is fitted into a guide rail 37 extending in a predetermined direction on the pedestal 36, and the wheel 35 is attached to the pedestal 38. It's listed above.

The operation of the apparatus of the present invention having an upper row configuration is as follows.

Prior to receiving the small bundle of signatures a', the fences 11, 11 on the entrance side (the left side in FIG. 4) of receiving the small bundle of signatures a' are opened as shown in FIG. Each fence 11, 11, 12, 12 is brought to a position corresponding to the size as described above. The fences 11, 11 on the side opposite to the entrance side (right side in FIG. 4) are closed as shown in FIG. In this closed state, the fence serves as a stop for the subsequent reception of the signature bundle a'. Fuens 12, 12
serves as a side support during the following reception of the small bundle of signatures a' and during one rotation of the turntable.

On the turntable 1 in this state, if the small bundle of signatures a' is the size of No. 4 in the JisB column,
The stack a' is fed in the direction A from the side of the turntable 1 (left side in FIG. 4) in a posture corresponding to the longitudinal orientation in the vertical direction in FIG. After the feed, the turntable 1 is rotated 90 degrees clockwise (or counterclockwise) in FIG. 4 by the motor 4 and then stopped. During the rotation, the fences 11, 11, which were initially open, are closed as necessary.

Next, the turntable 1 is left in its stopped state, and the upper feed plate 26 is moved to a required height by the plunger 28a of the hydraulic cylinder plunger device 28 and stopped. The folded small bundle stack a' thus lifted to the required height is stacked by the folded fold stack stacker 3 according to a conventionally known method.

Following the stacking process by the stacker 3,
The upper feed plate 26 is lowered to a fixed position, and the turntable 1 is rotated 90 degrees in the opposite direction, that is, counterclockwise (or clockwise) in FIG. Dynamically displaced.

Thereafter, upon receiving the second folding bundle a′, the turntable 1 is rotated by 90° in the opposite direction to that of the first folding bundle according to the preset settings, and then the turntable 1 is rotated 90° in the opposite direction to the first folding bundle a′. The stack of small bundles is lifted to the stacker 3.

Thereafter, in the same manner, the turntable 1 that has received the small bundle of signatures a' is repeatedly rotated and reversed by 90 degrees in the horizontal direction of each small bundle of signatures.

When the small bundle of signatures a′ is in row No. 5 of JisB, the small bundle of signatures for turntable 1 is
The feeding position a' corresponds to the horizontal orientation in the left-right direction in FIG. After feeding the small bundle of signatures a', the turntable 1 is rotated through 180 degrees and stopped (or left in the stopped state). If necessary, the entrance side fences 11, 11, which were initially open, are closed when the turntable 1 rotates.

Next, the small signature bundle stack a' on the turntable 1 is lifted by the upper feed plate 27 to a location of the small signature bundle stack stacking machine 3, and is subjected to the stacking process by the stacking machine 3.

After taking over the stacking process, the upper feed plate 27
is lowered into position.

And fence 1 on the entrance side of turntable 1
1 and 11 are opened in preparation for receiving the next small bundle of signatures a', and the fence on the opposite side is closed.

Under this condition, that is, while the turntable 1 remains displaced (or not displaced) by 180 degrees with respect to the first signature bundle a', the second signature bundle a' is fed into the turntable. conduct.

When this is completed, the second small bundle of signatures a' is lifted onto the stacker 3 without displacing (or displacing) the turntable 1 by 180°.

Thereafter, in the same manner, the horizontal direction 180° reversal process is performed one after another for each new collection of small bundles of signatures.

Regardless of the size of the small bundles of signatures a', the turntable 1, together with the frame 32, uses a hydraulic cylinder/plunger device 33 to move the small bundles of signatures a' in the desired direction alternately in the stacking order as required. The stacks are reciprocated in the direction of the arrow in FIG. 11 so that they are stacked in a staggered manner.

The stack of folded small bundle stacks stacked in the folding machine 3 is transferred from the stacking machine 3 to a binding device (not shown) connected to the folding machine 3. , are tied together with bands by a conventionally known method.

In the above-mentioned signature binding pre-processing, when the pusher 42 is at an intermediate position where it has not fully retreated from its forward position to its backward limit position, the elevator 2
The elevator 20 rises to its normal position in preparation for receiving the next small bundle of signatures, and the elevator 20
The pusher 42 is retracted so as to pass through the interior space 202c of the second embodiment.

In the present invention, in order to add a transfer means using an elevator and a turntable to a structure in which a small bundle of signatures and a stacker for stacking small bundles of signatures are arranged side by side, an elevator is arranged below the small bundle of signatures and the elevator is installed. The structure is such that a turntable is disposed adjacent to the stacker and below the stacker for stacking small bundles of signatures.

According to this configuration, in order to transfer the small bundle of signatures from the accumulator to the stacker, the first step is to lower the elevator that receives the small bundle of signatures,
There are four operations: advancing the cross-feeding means, retracting the same, and raising the elevator.The second step is rotating the turntable and raising the upper-feeding means (stacking).
The number of man-hours required between the two steps is almost balanced, and the processing efficiency of signatures can be improved by about 25 to 35% compared to the conventional method.

Moreover, the operation of the first step (unloading the stack of signatures) and the operation of the second step (reversing the stack of signatures) can be performed simultaneously, resulting in high machine efficiency. .

Effects of the Invention As is clear from the above, the present invention is capable of efficiently transferring small bundles of signatures from a stacker to a stacker in the signature bundling preprocessing device of the type described at the beginning, compared to the conventional method. , and also achieves the effect of obtaining high mechanical efficiency.
