DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signature conveying device which enables a predetermined number of signatures to be continuously carried in and stacked.

[0002]

2. Description of the Related Art As a conventional signature transporting device, a small bundle accumulating portion which receives incoming signatures so as to be aligned one after another is placed on a shelf maintained at a certain height and below the shelf. It is equipped with a lifter table that is installed and moved up and down.When a predetermined number of signatures are collected in small bundles on the shelf, the lifter table is raised and received, lowered, and transferred to the turntable with a push member. There is a type in which a turntable is rotated to change the direction of a small bundle and is pushed from below into an upper stacking machine to be stacked.

[0003]

However, in such a conventional technique, since the shelves of the small bundle accumulating portion are held at a constant height, the thickness of the small bundle in which signatures are accumulated is constant. If the shelf is lowered to make it thicker, the falling height of the signature will increase and it will become unstable.

Further, the lifter table cannot be lifted until the push member advances and retreats, and the speed at which signatures flow into the small bundle accumulating portion is reduced, so that the efficiency is reduced.

Further, in order to cope with, for example, a small small bundle of thin page signatures and a high small bundle of thick page signatures, the height of the upper surface of the turntable can be largely adjusted. When a cylinder having a long stroke is used, the vertical width of the entire device becomes large, and the device becomes large.

Furthermore, when stacking small bundles of signatures, if the turntable is raised, the small bundles cannot be carried onto the turntable, causing a problem that play time occurs and efficiency is reduced. there were.

The present invention has been made in view of the above-mentioned problems of the prior art, and when stacking small bundles, the signatures that flow in stably are stacked and the thickness of the small bundles is reduced. It is an object of the present invention to provide a signature transfer device capable of appropriately setting a signature.

A further object of the present invention is to provide a signature conveying device which can carry a small bundle into a turntable without interruption when stacking small bundles.

This will be described with reference to FIG.

FIG. 22 summarizes the description of the operation shown in FIGS.

In FIG. 16, when the inflow starts at a small bundle of 100 signatures, the upper fork 20 receives the signature, and the signature overlaps with the upper fork 20. At this time, a small bundle of signatures 100 is superimposed on the lifter 30.

In FIG. 17, before the upper fork 20 becomes full, the middle fork 40 moves to the ascending position to receive the overlapping signatures from the upper fork 20, and thereafter the signatures flowing in are superimposed on the middle fork 40. I do. When the middle fork 40 is receiving signatures, it descends according to the inflow of signatures, so that signatures can be received at appropriate heads and stacked. Before or after, the lifter 30 starts to rise.

In FIG. 18, when a predetermined number of signatures enough to make a small bundle are superimposed on the middle fork 40, the middle fork 4
0 falls to the down position. A small bundle is sandwiched and compressed by the descending middle fork 40 and the lifter 30 to release air.

In FIG. 19, the lifter 30 descends, and the push member 38 pushes out the small bundle from above the lifter 30 and carries it out to the turntable 50 side. Also during this time, the signatures flowing in overlap on the middle fork 40.

In FIG. 20, the lifter 30 is raised to the lower position of the middle fork 40, and the middle fork 40 delivers a small number of signatures on the lifter 30 and then retracts to the escape position. The push member 38 retreats back and forth, but, for example, because the relief groove 34 is formed in the lifter 30, the lifter 30 moves the push member 38 that moves back and forth.
Can be moved up and down without interference, and there is no need to wait for the movement of the push member 38 to be completed.

In FIG. 21, the middle fork 40 is directly lifted from the escape position. Before or after, the lifter 30 descends to the initial position. Since the lifter 30 descends according to the inflow while receiving the signatures, the signatures can be received and stacked at an appropriate head.

When the lifter 30 descends and the inflow starts at the break of a small bundle of 100 signatures, the upper fork 20 protrudes and the upper fork 20 receives the signature.
This overlaps with 0 and returns to the initial state shown in FIG.

Next, in the stacking section 50a, the small bundle of signatures carried in is received on the upper surface of the turntable 50, and is turned 180 degrees if necessary.

When a small bundle of signatures passes through one movable gate 53b, the other movable gate 53b is in the closed position and abuts against the front sides of the small bundle that has passed to align the small bundles. When inverted by 180 degrees, one movable gate 53b swings to the closed position, and the other movable gate 53b
May be swung to the open position to prepare for the next small bundle to be carried in.

When reversing 180 degrees, the servo motor 5
9 starts slowly, gradually increases the rotation speed, gradually reduces the rotation speed and stops, so that the small bundle on the turntable 50 does not collapse and the turntable 50 can be quickly reversed. it can.

When the output rods 56a and 57a of the vertically moving cylinder members 56 and 57 are both raised from the lower position and the lift-up member 52 lifts the small bundle on the turntable 50, the small bundle is moved to the middle basket 70. The finger members 72 receive and further raise the small bundle if necessary. If the height of the small bundle is low, the output rods 56a and 57a of the cylinder members 56 and 57 for vertical movement may be raised slightly.

When the finger bundle 72 of the middle basket 70 receives and raises the small bundle, the finger members 62
Swings outward, and the receiving port 6 of the large bundle 60
1 is open, and when the small bundle of signatures goes up, the signature is pushed into the large bundle basket 60, the finger member 62 swings inward, and the receiving port 61 closes, so that the large bundle is inserted into the large bundle basket. The bundles are held, and the small bundles are pushed one after another by the lifting and lowering of the finger members 72 of the middle basket 70, and are stacked from below.

When the small bundles are successively pushed in and stacked from below, the pusher 67 gradually rises while pushing down the folded part of the signature. Thereby, the folded portions of the signatures are aligned in the vertical direction, and the bundle of signatures does not collapse. When changing the pressing force of the pusher 67 according to the paper quality of the signature,
The air pressure of the pressing cylinder member 68 may be changed.

When a predetermined small bundle is superimposed to form a stack in a unit of binding, the large bundle basket 60 conveys the stack to the next banding process, which is the banding process. Even when the large bundle basket 60 is transporting the stack, the middle basket 70 receives and holds the small bundle on the turntable 50, and the small bundle of signatures is continuously received.

The stack conveyed to the band process is banded and carried out.

In the above embodiment, the small bundle is sandwiched between the lifter 30 and the middle fork 40 to remove air. However, if the middle fork 40 is not returned, the space between the upper fork 20 and the lifter 30 is You may ventilate the small bundle.

The interlocking operation of the upper fork 20, the lifter 30, and the middle fork 40 is not limited to the above-described embodiment.
For example, in FIG. 16, when the inflow starts at a break of a small bundle of 100 signatures, the signature may be received by the middle fork 40 instead of the upper fork 20. In this way, a predetermined amount of small bundles can be appropriately stacked on the lifter 30 without slowing down the signature inflow speed.

Further, the upper fork 20 may be formed in a simple shelf shape. The same applies to the middle fork 40.

Further, although the large bundle basket 60 and the middle basket 70 are formed in a basket shape, a stopper member for preventing the small bundle from collapsing at a predetermined position is provided if the small bundle can be stably stacked. What is necessary is just to be provided with.

[0076]

In addition, the thickness of the small bundle of signatures flowing into the upper fork can be set appropriately, and the signatures can be received at an appropriate drop and stably stacked.

Further, since a middle basket is provided between the turntable and the large bundle basket for properly carrying the small bundle into the large bundle basket from the turntable, the small bundle is cut off on the turntable without generating play time. Can be supplied without.

Further, when the middle fork of the small bundle accumulating section is receiving a signature, the middle fork is lowered in accordance with the inflow of the signature, so that the signature can be received at an appropriate drop. The signatures can be stacked stably.

Further, when the lifter of the small bundle collecting section receives the signature, the lifter is lowered in accordance with the inflow of the signature, so that the signature can be received at an appropriate drop. Can be stably stacked.

Further, since the lifter has a push member insertion groove, it is possible to raise the lifter and receive a signature without waiting for the push member to move forward and backward, thereby improving work efficiency. can do.

Further, the two small air cylinders for vertical movement are used in series, and the small bundles are moved up and down from low to high, so that the stroke length of each air cylinder is shortened. The height of the entire apparatus can be kept low, and the apparatus can be downsized.

Further, since the gate members are provided at both ends in the front-rear direction of the turntable, small bundles can be loaded into the turntable from both directions, so that the loading time is shortened and workability can be improved.
