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

A stacking machine for stacking signatures a in a certain number of small bundles is denoted by a reference numeral 2 and a stacking machine for stacking the signature small bundles a 'from the stacking machine 2 in a certain number of stages. Is provided with the reference numeral 3. The accumulator 2 and the stacker 3 are both known per se and are schematically shown in FIG. The stacking machine 2 and the stacking machine 3 are arranged side by side.

Below the stacking machine 2 (strictly speaking, the shelf 201 which can retreat in a predetermined direction in the stacking machine), an elevating table 202 is provided. Elevating tables 26 and 27, which are upper feeding means of the turntable 1 to be described later, are disposed adjacent to each other. To simplify the distinction between these tables,
The former is called a first elevating table, and the latter is called a second elevating table.

The first elevating table 202 is a fluid as an elevating device for driving the first elevating table 202 up and down when the first elevating table 202 is at a predetermined elevating position for receiving the signature small bundle stack a 'from the accumulator 2. Pressure cylinder 202d, 202d
In combination with the above, a frame body having a space 202c through which a later-described lateral feed pusher 42 can retreat by retreating is formed. The first lifting table 202 is a split type that can move up and down without contacting a rod 41a that drives the transverse feed pusher 42 back and forth by using the fluid pressure cylinder 41 as a driving device, more specifically, a table top plate 202a. The rod 41a is located above and the top plate 202a is
Split groove 202b that allows non-contact rise to 1a
It is a split type with.

The signatures a are discharged one after another from a pre-process (not shown) such as a rotary press to the start end of the belt conveyor 39 in a state shown in FIG. After passing through the belt conveyor 40, a predetermined number of signature bundles are collected, that is, received on a shelf 201 that can retreat in a predetermined direction of the stacking machine 2.

The small bundles a 'of the signatures a... Accumulated on the shelf 201 are determined by moving the shelf 201 to the left in FIG. 1 after receiving the signature small bundle a. Position first
On the lifting table 202. At this time, the table 202 has reached a predetermined height prior to the movement of the shelf 201.

After receiving the signature small bundle stack a ', the table 202 descends to the position indicated by the solid line in FIG. 1 and stops there.

Then, the signature small bundle stack a 'on the table 202 is traversed by the pusher 42, that is, the turntable 1 described later, in other words, the second lifting table 2
Feeding to 6, 27 is performed.

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

The above-described signature small bundle sorting process and signature small bundle accumulation process for a predetermined number of copies are repeatedly performed.

The turntable 1 is configured to be rotated through transmission gears 5 and 6 by a reversible rotary type motor 4 with a brake. The gear 5 is fixed to the shaft 7 of the motor 4, the gear 6 is fixed to the turntable 1, and the driving gear 9 of the cam switch 8 meshes with the gear 5. The switch 8 includes a first switch (not shown) that is turned on at the rotation speed or rotation phase of the gear 9 corresponding to the end of the 180 ° rotation of the turntable 1, and a 90 ° rotation of the turntable 1.

When these switches are turned on, a signal is input from the switch 8 to the inverter 10 of the motor 4 for driving the turntable 1, and the frequency from the inverter 10 causes the rotation of the motor 4 to reach a steady rating up to that time. When the motor 4 is switched to the low-speed rotation, and the turntable 1 reaches the 180-degree rotation or the 90-degree rotation, the motor is switched to the frequency corresponding to switching to the rotation as low as possible from the rotation speed. The current to the motor 4 is cut off, and at the same time, the brake of the motor 4 works, so that the motor 4 in other words, the turntable 1 stops at a fixed position.

A 180 ° rotation of the turntable 1 can be used to turn a signature in the horizontal direction of a signature of the fifth row in Jis B row, while a 90 ° rotation can be used in another certain dimension, for example Jis B.
It can be applied to reversal of the signature in row 4 in the horizontal direction. 180
When applied to inversion of the angle, the circuit belonging to the second switch of the switch 8 is not closed, and when applied to 90 ° inversion, the first switch of the switch 8 does not work. You should do so. At the time of the 90 ° angle reversal of the signature, the turntable 1 performs alternate 90 ° angular displacement on both the left and right sides (both in the clockwise direction and the counterclockwise direction in FIG. 4).
The rotation of the motor 4 is controlled. When the signature is turned 180 °, the rotation direction of the turntable 1 may be any one direction.

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

Prior to receiving the signature small bundle stack a ',
The entrances 11, 11 on the entrance side (the left side in FIG. 4) for receiving the aggregate a 'are opened as shown in FIG.
In addition, each fuence 11, at the position corresponding to the size of the signature a,
11, 12, and 12 are provided as described above.
The fences 11, 11 on the opposite side (right side in FIG. 4) from the entrance side are closed as shown in FIG.

In the turntable 1 under this condition, when the signature small bundle stack a 'is the size of the Jis B row No. 4, the stack a' is oriented in the direction corresponding to the vertical direction in FIG. It is fed in the arrow direction A from the side of the turntable 1 (left side in FIG. 4). After that, the turntable 1 is rotated clockwise (or counterclockwise) in FIG.
Is rotated 90 ° and stopped. At the time of rotation, the fences 11, 11 which were initially opened are closed as required.

Next, while the turntable 1 is kept stopped, the upper feed plate 26 is moved to the required height by the plunger 28a of the fluid pressure cylinder 28 and stopped. The signature small bundle stack a 'thus lifted to the required height is subjected to the stacking process of the stacking machine 3 according to a conventionally known method.

After taking over the stacking process by the stacking machine 3, the upper feed plate 26 is lowered to the home position, and the turntable 1 is ready for receiving the next signature small bundle stack a 'in the opposite direction to the previous one. That is, 90 ° counterclockwise (or clockwise) in FIG.
It is rotated and displaced.

Thereafter, when the second signature small bundle stack a 'is received, the turntable 1 moves 90 degrees in the opposite direction to that of the first signature small bundle stack according to a preset place.
After the rotation, the above-described stack of signature small bundles is again lifted to the stacking machine 3.

In the same manner, in the same manner, the turntable 1 which has received the signature small bundles a 'is repeatedly turned 90 ° in the horizontal direction and inverted to the stacking machine 3 for each signature small bundle.

When the signature small bundle stack a 'is of the fifth row of Jis B, the signature small bundle stack a' is fed to the turntable 1 in a horizontally long direction in FIG. After feeding the signature small bundle stack a ', the turntable 1 is rotated by 180 ° and stopped (or left stopped). If necessary, the entrance-side fences 11, 11 which were initially in the open state may be turnedtable 1
It is closed when rotating.

Next, the signature small bundle stack a 'on the turntable 1 is lifted to the place of the stacking machine 3 by the upper feed plate 27, 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 to a fixed position.

The entrance fences 11 of the turntable 1 are opened in preparation for receiving the next signature bundle a ', and the opposite fence is closed.

In this state, that is, with the turntable 1 being displaced (or not displaced) by 180 ° with respect to the first signature small bundle stack a ', the second signature small bundle stack a' is placed on the turntable. Send in.

When this is completed, the second turntable 1 is lifted to the stacking machine 3 without displacing (or displacing) the turntable 1 by 180 °.

In the same manner, in the same manner, a horizontal 180 ° inversion process between new signature small bundles is successively performed.
Is sent to

In the signature bundling pre-processing described above, the fences 11, 11 in the closed state on the side opposite to the entrance side serve as a stopper for receiving the signature small bundle stack a '. This has the following significance.

For example, the signature is either the A column or the B column of Jis. For example, the fourth column of the A column has the width of the third column of the A column, the fifth column of the B column has the length of the fourth column of the B column, and so on. Since the width of the signature of one step larger is equivalent to the length of the signature of one step smaller, the fences 11 and 11 serving as the stoppers in the closed state described above are, for example, No. 4 in row B. And the size of row B and the size of row B, the vertical and horizontal lengths of the signature small bundles, which are sent to the turntable 1 in different directions, are larger and smaller in size. .

As described above, according to the present invention, the fluences 11, 11, 11, 11, 11, 11,
The opening / closing and position setting of 11, 11 can correspond to the receiving state of the signature small-bundle assembly of the turntable 1, that is, the function can be made multi-type in enabling the correspondence.

The function is further enhanced if the turntable 1 can be displaced by 180 ° and 90 ° in a direction around the vertical axis. That is, even the small bundles of signatures sent to the turntable 1 in the vertical and horizontal directions different from each other, by changing the 180 ° and 90 ° angular displacement of the turntable 1 to make the vertical and horizontal directions the same. The stacks of the aggregates can be bundled with bands without changing the direction of the band binding portion of a binding device (not shown) connected to the stacking machine following the stacking machine. Because you can.

On the other hand, the fences 12, 12 serve as side supports when receiving the signature small bundle stack a 'and during one rotation of the turntable. This role is effective for signature small bundles of various sizes by moving the fences 12, 12 in a required direction and adjusting the position.

Regardless of the size of the signature small bundle stack a ', the turntable 1 may be mounted on the hydraulic cylinder 3 if necessary.
11 together with the frame 32, the signature small bundle stack a 'is reciprocated in the direction of the arrow in FIG. .

The stack of signature small bundles stacked by the above-mentioned stacking machine 3 is transferred from the stacking machine 3 to a tying device which is connected subsequently to the stack, and is processed by a conventionally known method. under,
It is bound by bands.
