Description

[Detailed description of the invention] (Field of industrial application) This invention is used in printing-related industries such as newspapers, magazines, and books. A paper sheet stacking device that receives and arranges paper sheets in a stacked state, and a transfer device that applies contact plates to the front and rear surfaces of a bundle of paper sheets formed by the stacking device and sends them to a bundling device. The present invention relates to a body alignment processing device.

(Prior Art) Conventionally, in the above-mentioned paper sheet alignment processing apparatus, as described in, for example, Japanese Utility Model Publication No. 58-4691, a stacking device and a transfer device each have a paper sheet alignment processing device. A holding member is provided to press both the front and back surfaces of the bundle of paper sheets arranged in a stacked state, and after the paper bundle held by the holding member provided on the stacking device is transferred to the holding member provided on the transfer device, It was configured to be transferred to a binding device and bound.

(Problems to be Solved by the Invention) Therefore, the paper sheets located near the front and back surfaces of the bound bundle of paper sheets may be damaged by the binding string or the like.

To prevent paper sheets from being damaged by such binding strings, place plates on both the front and back sides of the paper sheet bundle.
It is effective to bind from above this plate, but according to the above-mentioned conventional technology, the plate is artificially applied to the front and rear surfaces of the bundle of paper sheets transferred to the bundling device, and then this plate is tied. There was a problem in that work efficiency was reduced because they had to be tied together.

The present invention aims to solve the above problems.

(Means for Solving the Problems) The characteristic configuration of the present invention for achieving the above object is to sequentially receive paper sheets 3 conveyed in an upright position, and to arrange a plurality of paper sheets 3 in a comb-like manner. A second holding member 4A with a plate insertion space G provided behind the support body 4a.
and a second pressing member 4F having a plate insertion space G provided at the rear of the comb-shaped support 4f, a stacking device 4 that aligns the paper sheet bundle 3 in a stacked state, and a paper sheet bundle 3 formed by the stacking device 4. ' and the contact plates 7 inserted into the contact plate insertion spaces G and G of both presser members 4A and 4F are pushed out in a direction perpendicular to the conveying direction of the paper sheets 3 and fed into the bundling device 10. In the paper sheet alignment processing apparatus equipped with the device 8, a contact plate 7 that is applied to both the front and rear surfaces of the paper sheet bundle 3' has approximately the same vertical and horizontal dimensions as the paper sheet bundle 3', and has a thickness similar to that of the paper sheet bundle 3'. A lifting mechanism 5A that sequentially moves upward a plurality of backing plates 7 placed in a horizontal or almost horizontal position, and a lifting mechanism 5A that sequentially moves the plurality of backing plates 7 placed in a horizontal or almost horizontal position;
A contact plate supplying device 5 equipped with a pull-out mechanism 5C that pulls out sheets one by one to the side, and an attitude changing mechanism 6C that converts the contact plate 7 pulled out from the contact plate supplying device 5 into a vertical position.
Then, the second plate 7, which is in a vertical position, is
The stacking device is provided with a pressing plate insertion device 6 equipped with a pressing plate pushing mechanism 6A for pushing the front and rear holding members 4A, 4F into the pressing plate insertion space G from above, It has the following effects.

(Function) The lifting mechanism 5A of the plate supply device 5 sequentially lifts the plates 7 stacked in a horizontal or almost horizontal position upward, and the pull-out mechanism 5C positions the plates 7 at the uppermost position. The contact plates 7 are sequentially taken out to the side one by one.

The contact plate 7 pulled out from the contact plate supply device 5 is subsequently sent to the contact plate insertion device 6, where its attitude is changed to a vertical state by the attitude changing mechanism 6C, and then transferred to the contact plate pushing mechanism 6A. Therefore, the second front presser member 4A and the second rear presser member 4F located below are pushed into the respective abutting plate insertion spaces G from above.

When the press plate 7 is inserted into the press plate insertion space G of both presser members 4A and 4F that support the front and rear surfaces of the sheet bundle 3', the pushing part 8A of the transfer device 8 presses both ends of the press plate 7. Both pressing members are operated in a direction perpendicular to the conveyance direction of the paper sheet 3 in a state in which they protrude into the abutment plate insertion space G, and thereby the paper sheet bundle 3' and the abutment plates 7 on both the front and rear sides thereof are pressed together. are fed into the binding device 10 as one unit.

(Effects of the invention) In this invention, a relatively thick backing plate is automatically supplied to both the front and back sides of the paper bundle by the backing plate supply device and the backing plate insertion device, and the backing plate is automatically fed to both the front and back sides of the paper bundle and The front and rear contact plates are transferred as one to the binding device, greatly improving the efficiency of the work of inserting the contact plates.

In addition, by installing the plate feeding device at a low location, it is possible to keep the height of the entire alignment processing device low, and replenishment of the plate can be easily done at a low location, which is practical. It is extremely convenient.
