Will be soft landed on top of each other.

Then, the side plates 311a and 311b descend to the predetermined position as they are, and when the sensor 390c (FIG. 7) detects that the side plates 311a and 311b have descended to the predetermined position, the motor 461 (FIG. 7) reverses based on the detection signal. And then each side plate 3
11a, 311b and the pressing plate 3 pressing the signature P
40 (FIG. 7) rises to a predetermined position. Each side plate 311
When a and 311b move up to a predetermined position, the side plates 311a and 311b stop at the predetermined position based on the signal from the sensor 390b (FIG. 7) that detects this.

Here, in FIG. 14 (c), when there is no signature Po that has already been supplied below the signature P to be supplied, the locking members 312a and 312b do not rotate.
The signature P is lowered to a predetermined position while being locked by the locking tools 312a and 312b, and then raised to the original position.

Therefore, as means for preventing such an operation, two stoppers that come into contact with the movable pieces 314 of the respective locking members 312a, 312b, such as the side plates 311a, are used.
It may be arranged at the lowest point where 311b should descend. If it does so, each side plate 311a, 311b
Is lowered to the lowest point, each locking member 312a, 312b
Since the movable piece 314 of is brought into contact with the stopper to rotate,

As shown in FIG. 5 (b), the guide rail 222a (b)
The movable plate 220 moves to the end of the lift unit 100 side. When the pinion 225 is driven, another pinion 227 (FIG. 6) coaxial with the pinion 225 is also driven. Therefore, the movable plate 217 provided with the rack 228 that meshes with the pinion 227 is also provided on the lift portion 100 side. Moving.

In this case, the gears 215a and 215b attached to the movable plate 217 drive the chain 214, but the chain 214 includes the movable plate 220 and the carrier plate 21.
Since it is fixed to 1, the carrier plate 211 fixedly connected to the chain 214 is driven by the chain 214,
As shown in FIG. 15C, the carrier plate 211 moves to the lift unit 100 side, and thus the carrier plate 211 moves to the lift unit 100 side.

When the carrier plate 211 is moved to the side of the supply unit 300 (FIG. 1), the same procedure as described above is applied to FIG.
5 (c).

If the above-described structure is used, for example, when the tooth pitch of the pinion 227 is set to ½ of the tooth pitch of the pinion 225, the movable plate 217 is smaller than the moving distance of the movable plate 220. The carrying plate 211 connected to the movable plate 217 is moved to the front by ½ of the moving distance.
Moves further forward by the moving distance of the movable plate 217. That is, up to a distance twice the moving distance of the movable plate 220, a supporting member 210a (b-
It is possible to move f). Therefore, the guide rail 222a (b) to be installed can be shortened, which is extremely effective when the space for installing the guide rail 222a (b) is restricted due to the design of the device.

The operations of the apparatus described above are sequentially repeated, and the signatures are continuously supplied to the separating device for separating and placing the signatures one by one on the belt conveyor for feeding the signatures to the collator. Will be done.

[0073]

As is apparent from the above description, according to the present invention, as in the conventional example shown in FIG.
Instead of rotating the cage containing the signatures and lifting them to the transport section, the cage is lifted vertically to the transport section, so there is no need for space for the cage to rotate, making it a smaller space. However, it becomes possible to install and operate the device.

Moreover, since the cage for accommodating the signatures is not rotated, there is no danger of the cage colliding with the operator of the apparatus, and the safety of the work can be ensured. As a result, there is no need to take protective measures to ensure the safety of work. Therefore, the effects provided by the present invention are extremely large in practice.
