Then, just before the movable base 12 reaches the highest point, the locking pawl 46 is pushed back by the biasing force of the spring 44, and the protrusion 45
The tip of the locking pawl 46 that had been protruding toward the lower surface side can be removed from the protruding piece 45.

Next, the operation of the above embodiment will be explained.

First, before a detector (not shown) detects that the paper bundle A has been conveyed on the conveyor belt 4, the stopper 40, as shown in FIG. The lower end of the movable base 12 protrudes into the conveyance path 1, and the movable base 12 to which the first stamp 16 and the pressing plate 20 are attached is at the uppermost position.

Also, a stamp holder 30 holding the second stamp 29
is in a horizontal position.

Next, when the paper bundle A is detected by the detector, the motor 26 of the movable base operating mechanism 21 starts rotating, and the cam arm 24 starts rotating clockwise from the solid line position in FIG.

Then, as shown in FIG. The spring 44 protrudes in the direction of the arrow due to the biasing force of the spring 44.

On the other hand, the paper bundle A comes into contact with the stopper 40 and is forcibly stopped at a fixed position against the conveying force of the conveyor belt 4.

Next, as shown in FIG. 48, as the movable base 12 moves downward, the pressing plate 20 comes into contact with the upper surface of the paper leaf handle A, supports the paper leaf handle A between it and the lower surface guide 5, and then , the first stamp 16 is pressed.

At this time, the first stamp 16 and the pressing plate 20 are independently and elastically supported by the movable base 12, so that even if the thickness of the paper leaf handle A changes somewhat, the paper leaf handle A can be reliably and elastically supported. It will come in contact with the top surface of.

On the other hand, the tip inclined surface 46a of the locking pawl 46 is connected to the stopper 40.
When the locking pawl 46 hits the upper edge of the protruding piece 45 integral with the upper surface thereof, the locking pawl 46 begins to move in the direction of the arrow under the biasing force of the spring 44.

Next, as shown in FIG. 42, when the movable base 12 is located at the lowest point, the tip of the locking pawl 46 gets over the protrusion 45 and protrudes to the lower surface side, and the pressing plate 20 and the first stamp 16, appropriate pressing force and stamping pressure can be obtained, and reliable stamping can be performed.

On the other hand, at this time, when the paper bundle A is detected by a detector (not shown) as shown in FIG. 5, a second stamp imprinting command signal is output, and after a time T1 has elapsed, the rotary solenoid 35 is activated.

Then, the stamp holder 30 rotates to remove the second stamp 2.
The stamp surface 29 a of No. 9 hits the end surface of the sheet bundle A on the conveyance direction side which is completely pressed by the pressing plate 20 and is stamped.

Next, the movable base 12 rises as shown in FIG. The stopper 40 also rises accordingly.

Therefore, the conveyance of the paper bundle A whose conveyance was forcibly stopped by the stopper 40 is restarted.

At this time, as shown in Fig. 5, the rotary solenoid 3
The operation time T2 of No. 5 is shorter than the pressing time of the pressing plate 20, and the second stamp 29 has returned to its original position when the pressing is finished, and does not prevent the conveyance of the paper bundle A.

Next, just before the movable base 12 reaches the highest point as shown in FIG. 44 and retreat in the direction of the arrow.

At this time, the rear end of the paper bundle A is already at a position away from the position of the stopper 40 in the conveyance direction.

Next, when the movable base 12 reaches the highest point, the locking claw 4
The tip of the stopper 40 is removed from the locking plate 45, and the stopper 40 is moved downward by the biasing force of the spring 41 and its own weight, and returns to the state shown in FIG. 4A.

Note that when the detector 28 detects that the movable base 12 has reached the uppermost point, the motor 26 stops, and the stamping operation on the paper bundle A is completed.

Then, when the subsequent paper bundle A is detected, the above operation is repeated again.

In this way, as shown in FIG. 6, a stamp 50 is stamped on the top surface of the binding band 49 of the paper bundle A with the first stamp 16, and a stamp 51 is stamped on one end surface with the second stamp 29.

In the above-mentioned embodiment, the conveyance path 1 is constructed by the conveyance belt 4, but it may be constructed by a slide, a conveyance roller, etc.

Further, although the movable base actuating mechanism 21 is configured to use the cam arm 24, the motor 26, etc., the present invention is not limited thereto, and a solenoid, hydraulic pressure, pneumatic pressure, etc. may be used.

Furthermore, although the rotary solenoid 35 is used as the driving means for the second stamp 29, a motor may also be used.

In addition, it goes without saying that the present invention is not limited to the above-mentioned embodiments, and that various modifications can be made without changing the gist of the present invention.

As explained above, according to the present invention, although the structure is simple, only the object to be stamped can be temporarily stopped without stopping the conveyance operation of the conveyance path, and the stamp can be quickly and reliably stamped on the object in this state. can be done.

In addition, since the stopper is linked with the movable base on which the pressing body, stamp, etc. are attached, and is moved back and forth in the direction toward and away from the conveyance path, the movement range of the stopper can be increased, and the object to be stamped after stamping can be moved back and forth. This has the effect of ensuring reliable transportation.
