The present invention will now be described with reference to the drawings showing an embodiment of the present invention.

A stacking machine for stacking the signatures a into a certain number of small bundles is designated by a reference numeral 2, and a stacking machine for stacking a small stack of signatures a'from the stacking machine 2 in a certain number of stacks. Is denoted by reference numeral 3. Both the stacker 2 and the stacker 3 are known per se and are shown diagrammatically in FIG. The stacking machine 2 and the stacking machine 3 are arranged side by side.

A first lifting table 202 is disposed below the stacking machine 2 (strictly speaking, a shelf 201 that can be retracted in a predetermined direction in the stacking machine), and below the stacking machine 3. A second lifting table 26 adjacent to the lifting table 202,
27 are arranged.

The first lifting table 202 is a fluid as an elevator that drives the first lifting table 202 up and down when the first lifting table 202 is in a predetermined raised position for receiving the folded small bundle stack a'from the stacker 2. Pressure cylinder 202d, 202d
In combination with this, a lateral feed pusher 42, which will be described later, forms a frame having a space 202c through which the pusher 42 moves backward. Further, the first lifting table 202 is a split type that can move up and down without contacting the rod 41a that drives the lateral feed pusher 42 back and forth using the fluid pressure cylinder 41 as a driving machine, more specifically, above the table top plate 202a. The rod 41a occupies the top plate 202a
It is a split type with a split groove 202b that allows it to rise in a non-contact manner with respect to a.

The signatures a are discharged one by one from the preceding step (not shown) such as a rotary press to the starting end of the belt conveyor 39 in the state shown in FIG. After being divided into, the predetermined number of small bundles of signatures are collected, that is, received on the shelf 201 which can be retracted in a predetermined direction of the stacking machine 2 via the belt conveyor 40.

The small bundle stack a'of the signatures a ... Collected on the shelf 201 is received by the signature small stack stack a ', and the shelf 201 is retracted to the left in FIG. First in position
Is lowered onto the lifting table 202. At this time, the table 202 is raised to a predetermined height before the retracting 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 folded small bundle stack a'on the table 202 is laterally fed by the pusher 42, that is, the turntable 1 described later, in other words, the second lifting table 2.
It is sent to 6, 27.

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

The above-described signature small bundle sorting processing and signature small bundle accumulation processing 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. The gear 5 is fixed to the shaft 7 of the motor 4, the gear 6 is fixed to the turntable 1, and the drive gear 9 of the cam type switch 8 is engaged with the gear 5. The switch 8
Is the first switch-on at the rotation speed or rotation phase of the gear 9 corresponding to the end of the 180 ° angle rotation of the turntable 1.
And a second switch (not shown) which is switched on at the rotation speed or the rotation phase of the gear 9 corresponding to the end of the 90 ° angular rotation of the turntable 1. When the switch is 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 is changed to the motor 4

When the folded small bundle stack a'has a size of Jis B row No. 4 on the turntable 1 under this state, the stack a'corresponds to the vertically long direction in FIG. The turntable 1 is fed in the direction of arrow A from the side (left side in FIG. 4). After the feeding, the turntable 1 is rotated 90 ° clockwise (or counterclockwise) in FIG. 4 by the motor 4 and stopped. At the time of the rotation, if necessary, the fences 11, 11 that were initially open are closed.

Then, while the turntable 1 is kept in the stopped state, 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 stacking processing by the stacking machine 3 according to a conventionally known method.

After taking over to the stacking process by the stacking machine 3, the upper feed plate 26 is lowered to a fixed position, and the turntable 1 prepares to receive the next signature small bundle stack a'in the opposite direction, That is, 90 ° counterclockwise (or clockwise) in FIG.

After being rotated by 0 °, the above-described signature small bundle stack is lifted up to the stacking machine 3.

Thereafter, in the same manner, the turntable 1 which has received the small stack of signatures a'is repeatedly rotated by 90 ° in the horizontal direction of each small stack of signatures, and the upper feed to the stacking machine 3 is repeated.

When the small stack of signatures a'is of the number 5 in Jis B row, the feeding position of the small stacks of signature a'to the turntable 1 corresponds to the laterally long direction in the horizontal direction of FIG. After feeding the small bundle stack a ′, the turntable 1 is rotated 180 ° and stopped (or left in a stopped state). If necessary, the entrance-side fences 11, 11 which were initially in the open state are closed when the turntable 1 rotates.

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

After taking over to the stacking process, the upper feed plate 27 is lowered to a fixed position.

Then, the folds 11, 11 on the entrance side of the turntable 1 are opened in preparation for receiving the next folded small bundle stack a ', and the folds on the other side are closed.

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

After that, turntable 1
Without displacing (or displacing) by 180 °, the second small stack of stacks a ′ is lifted to the stacking machine 3.

Thereafter, in the same manner, a horizontal 180 ° inversion process between the new small bundle stacks and the stacking machine 3 are successively performed.
The upper feed is performed.

Regardless of the size of the folded small bundle stack a ', the turntable 1 is provided with the fluid pressure cylinder 3 as required.
11, together with the frame 32, the small bundle stack a'is reciprocated in the arrow direction in FIG. 11 so as to form a so-called staggered stack in which the stack stack a'is alternately displaced in the stacking direction in the stacking direction. .

The stack of folded small bundle stacks stacked by the stacking machine 3 is transferred from the stacking machine 3 to a binding device (not shown) connected subsequently to the stacking machine 3, The band is bound by a conventionally known method.

In the present invention, the first elevating table disposed below the stacking machine is combined with the drive elevating machine of the table to form a frame body through which the lateral feed pusher can slip through. It is a split type that can move up and down without contacting the drive rod of the lateral feed pusher.

According to the construction of the first elevating table of the present invention, the first elevating table is moved to the next stack of small bundles in the intermediate stage in which the transverse feed pusher does not completely return from the forward position to the backward limit. To retreat the transverse feed pusher and raise the first elevating table in parallel so that the transverse feed pusher can be retracted without being disturbed by the first elevating table in preparation for reception. To enable.

[0048]

As described above, according to the present invention, the first raising / lowering table for receiving the stack of signature small bundles to be lowered from the stacking machine and the lateral feed pusher for sending out the stack of signature small bundles on the table are delivered. Since it can be carried out in parallel with the retreat of the above, in the signature binding pretreatment device of the above-mentioned type, the cycle of the transverse feeding of the signature small bundle stack can be cycled up, and the efficiency of the signature binding pretreatment can be improved. .
