Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signature transporting and accumulating device for transporting signatures discharged from a rotary press, for example, by individually retaining and transporting the signatures by a number of retaining means.

[0002]

2. Description of the Related Art As described above, a signature is held and conveyed by a carrier such as a carrier having a holding means such as a one-part grip type grip mechanism, and the signature is gripped at a predetermined position. A signature conveying and accumulating device for further releasing and accumulating and accumulating on the accumulating means is known, for example, Japanese Patent Publication No. 1-387.
No. 43 bulletin and “Exploring automation of printing and shipping” (Showa 5)
There is one shown in page 109, Fig. 4, stacking system, page 109, published by The Japan Newspaper Association on July 20, 8th.

In the conventional example disclosed in Japanese Examined Patent Publication No. 1-38743, printed materials conveyed in a scale-like manner on a conveyer are conveyed while a copy gripper holds one copy at a time. Two deposition chambers are provided one behind the other in the transporting direction of the transporting device, and the gripper is opened above each deposition chamber to supply the printed matter to the deposition chamber. Then, when predetermined deposition is performed in one deposition chamber, deposition is continuously performed in the other deposition chamber, and the operation of emptying the one deposition chamber is repeated during this period. What is shown in "Exploring the automation of printing and shipping" (July 20, 1983, Japan Newspaper Association, page 109, Figure 4, stacking system) is the above-mentioned Japanese Patent Publication No. 1-387.
A deposition chamber provided in the transport direction by a transport device using a one-part gripper gripper similar to that of Japanese Patent No. 43 publication is rotated by a 180-degree rotation mechanism, and a printed matter supplied by opening the gripper above the deposition chamber is rotated by a predetermined number of 180. It is a mechanism that can be stacked alternately.

[0004]

However, in the mechanism of the above-described conventional folded-sheet conveying and accumulating device, since folded portions such as newspapers have thick folds, when folded in the same direction only, After being discharged from the stacking means as a stack with a raised side, the load collapses, which not only causes inconvenience to subsequent processing, but also often causes the signature to become dirty or damaged and unusable. It was

Further, in the deposition chamber equipped with a rotating mechanism, the accumulated printed matter is contaminated or damaged by the impact of the rotating and stopping motion of the rotating mechanism. Due to the existence of a rotating mechanism and the addition of a mechanism for sufficiently enduring repeated rotation and stop, downsizing and simplification were difficult, and the integration processing efficiency was not very good. Therefore, there has been a demand for a simplified stacking device that can selectively change the orientation of a signature and create a stable stack.

The present invention has been conceived in view of the above, and in the conveying means up to the stacking means, the signatures are alternately changed in direction by a predetermined number of copies, so that the stacking means are rotated and stacked as in the conventional case. It is not necessary to do so, and the rotary drive mechanism can be omitted at all, simplifying the machine,
Furthermore, regardless of the speed at which the signatures are conveyed to the stacking means, it is possible to continuously drop the signatures having different directions for each predetermined number of copies onto the stacking means, which enhances the stacking processing capacity, An object of the present invention is to provide a signature stacking and accumulating device that can eliminate the damage or the damage due to the load collapse and the impact in the deposition chamber, and can contribute to the elimination of the damaged paper due to the damage or the damage.

[0007]

In order to achieve the above-mentioned object, a signature conveying and accumulating device according to the present invention comprises a accumulating means for accumulating signatures and a collecting means for conveying the signatures to the accumulating means. Conveying means provided via the above, holding means provided at the conveying means at a predetermined interval and individually holding the signatures, holding assisting means for holding the signatures in the holding means, and accumulating the retained signatures Release assisting means to release towards the means,
After the action of the holding assisting means and before the action of the releasing assisting means, the holding means is selectively turned to the right or left by a predetermined angle and the direction changing means is arranged, and the signatures are changed in number by a certain angle and accumulated. It is configured to do.

[0008]

[Operation] The signatures individually held by the holding means provided at intervals in the conveying means are used to change the holding means selectively by the direction changing means provided in the middle of the conveying to the right or left at a predetermined angle. By being rotated, the orientation of the held signature can be changed. The release assisting means provided above the collecting means acts on the holding means to release and drop the signatures to be held. As a result, the stacking means creates stacks which are stacked alternately while being deviated by a predetermined angle for each predetermined number of copies.

[0028]

According to the present invention, since the signatures are alternately turned in a predetermined number of copies in the conveying means to the stacking means,
It is not necessary to rotate the stacking means each time as in the conventional case, and the stacking means can be omitted, and the rotation driving mechanism can be omitted altogether, resulting in simplification of the machine. Furthermore, regardless of the speed at which the signatures are conveyed to the accumulating means, signatures having different directions can be continuously dropped onto the accumulating means for each predetermined number of copies, so that the accumulating capacity is improved. Further, it is possible to eliminate the damage or the damage due to the collapse of the stack and the impact in the deposition chamber, which contributes to the elimination of the damaged paper due to the damage or the damage.
