It is characterized in that it is provided with a scraping mechanism that operates to.

[0007]

In the book stacking apparatus having the above-described structure, folding of the book is performed by gripping it with the gripper, and the gripper moves the book one by one onto the stacking table so that a bundle of books can be aligned well. Is formed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of a first printed book stacking apparatus according to the present invention, and FIG. 2 is a side view of the same.

In FIG. 1, 1 is a folder table, 2 is a chopper blade mounted on a swing shaft 3, and 4 is a conveyor belt running on the folder table 1. The chopper blade 2 is sandwiched by the conveyor belt 3. Being a folding table 1
The printing book P, which is incident on the upper side up to the stopper 5, is folded so as to project downward from the gap of the folder table 1. 6 is a reject nip roller that can move up and down, and 7 is a transport nip roller. Further, 8 is a stacking table arranged below the folder table 1, and has a supporting member 9 which can be gradually moved backward.

A gripper 10 is attached to a swing shaft 11, and has a clamp 13 urged by a spring 12 at its tip, and the clamp 13 is pushed by a push rod 15 reciprocating by a cam 14. Open and close. That is,
When the clamp 13 that is opened when the gripper 10 is raised is closed by the spring 12 near the top dead center of the gripper 10, the clamp P descends while holding the book P, and opens near the bottom dead center to release the book P. The cam shaft 16 to which the cam 14 is attached is adapted to rotate once for one reciprocation of the gripper 10. Reference numeral 17 is a guide for guiding the print P when the gripper 10 descends. Then, at the tip of the stacking table 8, the gripper 10 can pass through and the separated book P stays on the stacking table 8.
A protrusion 8a corresponding to the groove 10a of the gripper 10 is provided.

Reference numeral 18 denotes a blower, and when the gripper 10 grasps the printing plate P and approaches the stacking table 8, the printing plate P is held.
It is designed to send the wind so that the guide 17
Together with this, it constitutes a fan mechanism. In addition, instead of disposing the blower 18, the guide mechanism 1
The book P may be stood by swinging 7 itself in synchronization with the gripper 10. Reference numeral 19 denotes a pair of scraping plates provided on both sides of the stacking table 8. As shown in FIG. 3, the gripper 10 separates the print P from the stacking table 8 and at the same time the support P supports the print P. A scraping mechanism that operates so as to be held between is constructed.

The operation of the book stacking apparatus having the above structure is as follows.

The printing book P, which has passed through known portions such as a triangular plate, a nipping roller, a cutting device, and a gripper folding device, from the printing section of the rotary printing machine, hits the stopper 5 while being held by the conveyor belt 4. Then, the chopper blades 2 are folded one by one and further protruded downward from the gap of the accumulating table 1, and are inserted between the clamps 13 of the gripper 10 waiting near the bottom dead center of the chopper blades 2. In this case, the sagging at the time of printing or the sagging caused by a printing error is caused by raising the stopper 5 and lowering the reject nip roller 6, so that the conveyor belt 4 is pressed by the reject nip roller 6 and the transport nip roller 7. The sheet is sandwiched and discharged toward the left side in FIG.

At the same time when the chopper blade 2 starts to return to the upper position, the gripper 10 closes the clamp 13 by the synchronous drive system, and the folding of the book P is completed. Here, the folding degree of the book P can be adjusted by appropriately setting the force for closing the clamp 13. Then, the gripper 10 swings approximately symmetrically with the chopper blade 2, and the gripped book P is drawn along the guide 17 onto the stacking table 8. Then, when the gripper 10 approaches the bottom dead center, the tilting mechanism acts so as to stand up the copy book P, and at the same time when the gripper 10 releases the copy book P on the stacking table 8, the scraping plate 19 holds the copy book P. , The printing sheets P are accumulated between the supporting member 9 and the supporting member 9 which gradually advances to the left in FIG. In this way, the printed sheets P, on which a predetermined number of copies are accumulated, are transferred from the accumulation table 8 to a cassette or the like by an appropriate means such as a takeout hand.

FIG. 4 is a front view showing an embodiment of a second printed book stacking apparatus according to the present invention, and FIG. 5 is a side view of the same.

The printed book stacking apparatus of this embodiment is different from that of the previous embodiment in that a swinging chopper blade is not used. That is, the conveyor belt 4 is provided on the lower side of the folding machine table 1, and the fixed blade 20 is attached in parallel with the conveyor belt 4, so that the printing book P sent by the conveyor belt 4 is mounted on the fixed blade 20. It is made to fold down. Then, the gripper 10 holds the portion of the book P that rides on the fixed blade 20. The rest of the configuration is the same as that of the previous embodiment, and corresponding parts are designated by the same reference numerals.

In the book stacking apparatus of the present embodiment, when the book P is sent by the conveyor belt 4, it rides on the fixed blade 20 and folds downward while proceeding, and then hits the stopper 5 and stops. Then, the gripper 10 goes to hold the folded part of the copy book P,
It swings so as to be drawn onto the accumulation table 8. In this case, the sagging at the time of printing or the sagging caused by a printing error is discharged toward the left side in FIG. 5 by lowering the stopper 5 and temporarily retracting the fixed blade 20 upward. The operation after the gripper 10 holds the copy book P is the same as in the previous embodiment.

[0019]

As described above, according to the printing book stacking apparatus of the present invention, the folding and stacking operations are performed almost simultaneously by gripping the printing book with the gripper.
Since it is possible to eliminate the instability of the printing plate posture that has occurred with deceleration using a conventional impeller and the subsequent conveyor conveyance, it is possible to eliminate the unevenness of the accumulated printing plate bundle,
In addition, it is possible to prevent troubles in stacking.
