JPH02305762A - Pile-up device for forms - Google Patents

Abstract

PURPOSE:To enable forms to be piled up while damages such as cracks and bends at the tip end of the forms fed into a housing box from a carrying passage are being prevented by providing a shock absorbing means at a position with which the forms on a guide plate are brought in contact. CONSTITUTION:Forms 1 carried in are fed into a housing box 2 so as to be brought in contact with a main guide plate 5a provided in the inside of the housing box 2. In this case, since a shock absorbing member 6 is provided for the main guide plate 5a, shock at the time of collision is damped while damages such as cracks and bends at the tip end of the forms are prevented so that the forms 1 can thereby be piled up within the housing box 2.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet stacking device, and in particular, the fed paper sheets are brought into contact with and stopped on a guide plate inside a storage box so that the paper sheets stack on the guide plate surface. The present invention relates to a paper sheet stacking device which is suitable for stacking paper sheets along the front edge of the paper sheets without causing damage such as scratches or folds to the leading edge of the paper sheets.

[Conventional technology]

A conventional device of this type, as described in Japanese Utility Model Application Publication No. 62-34564, sends paper sheets conveyed one by one through a conveyance path into a storage box, and places the sheets on a guide plate provided inside. The front ends of the leaves are brought into contact and stopped, and the leaves are deposited along the surface of the guide plate. However, when the paper sheet comes into contact with the guide plate, the front edge of the paper sheet may be damaged.
Sufficient consideration was not given to the possibility of damage such as breakage.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into account the impact that the paper sheets received when they come into contact with the guide plate provided inside the storage box are alleviated. There is no particular problem if the width of the guide plate can be configured to be larger than that of a sheet book, but if it is combined with a mechanism for reseparating or taking out the stacked sheets, it may be necessary to In some cases, it is not possible to increase the width of the guide plate.

In such a case, the edge of the guide plate comes into contact with the front edge of the paper sheet, and the impact causes damage to the curved edge of the paper sheet.

There was a problem that damage such as bending occurred.An object of the present invention is to provide a buffer member at a position of the guide plate where the paper sheets come into contact with the guide plate, By providing the buffer member on the main guide plate and arranging other items set back from the surface of the main guide plate, damage such as scratches and folds on the front edge of the paper sheets can be prevented. It is an object of the present invention to provide a paper sheet stacking device that prevents this from occurring.

[Means to solve the problem]

The above purpose is to provide a buffer member at a position where the transported paper sheets are sent into a storage box and come into contact with a guide plate provided in the storage box, and in the case where the guide plate is divided into a plurality of parts, This can be achieved by providing the main guide plate with the buffer member and arranging the other parts so as to be set back from the surface of the main guide plate.

[Operation] The conveyed paper sheets are fed into the storage box and come into contact with a guide plate provided inside the storage board, but since the guide plate is equipped with a buffer member, the fr at the time of contact is Since the impact is alleviated, damage such as scratches and folds on the front edge of the paper sheet can be prevented from occurring.

In addition, in the case where the guide plate is divided into a plurality of parts, the main guide plate is provided with the buffer member, and the other parts are arranged so as to be set back from the surface of the main guide plate. Even when the paper sheet that has been fed is turned diagonally, it first contacts the main guide plate, and after the impact is alleviated, it contacts other objects, so the other guide plates also affect the paper sheet. It will not cause any damage.

〔Example〕

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

The same parts were given the same symbols throughout each round.

First, the configuration of this embodiment will be described with reference to FIG. In FIG. 1 showing a side sectional view of this embodiment, there are shown a feed roller 3a that feeds paper sheets 1 sent in the direction of arrow P by a conveyance path not shown in the figure into a storage box 2, and the fed paper. The leaf 1' is rotated by a power source that gives momentum and prevents it from tilting downward.

Further, a counter roller 3b is arranged to face the feed roller 3α and rotate as a driven member. A main guide plate 5 is installed inside the storage box 2.
α and sub-guide plates 5b are arranged on both sides thereof. The sub-guide plate 5b is set back from the surface of the main guide plate SCL and forms a step near the upper end position of the sheet group IN. Furthermore, when viewed from above, it has a V-shape.

In addition, buffer members 6 are provided at both ends of the main guide plate at the position where the fed paper sheets 1' contact, and FIG. 2 shows the main guide plate 5α, sub guide plate 5b, and buffer members 6.
FIG. In FIG. 2, buffer members 6 made of thin spring plates are provided at both ends of the main guide plate 5CL so as to be flush with the main guide plate 5CL.

Next, the stacking operation of paper sheets 1 according to the present embodiment configured as above will be explained. In FIG. 1, paper sheets 1 are fed in the direction of arrow P from a conveyance path not shown at @ by a feed roller 3rL and an opposing roller 3b that rotates in a driven manner, and then by a bladed roller 4. After gaining momentum, the front end comes into contact with the main guide plate 5a and stops, then falls and is deposited along the main guide plate 5α surface. In the prior art, damage to the paper sheets 1' that are fed in is caused by scratches caused by the front end of the paper sheets 1' coming into contact with the corners of the main guide plate 5α, or damage to the paper sheets 1' that are fed diagonally. The main cause of the bending was when the corner of ``' hit the sub-guide plate 5b. As shown in FIG. 3, in this embodiment, buffer members 6 are provided on both sides of the main guide plate 5α, so that it is possible to prevent scratches from hitting the corners. Further, since the sub-guide plate 5b is set back from the surface of the main guide plate 5α, the corners of the paper sheets 1' do not directly contact the sub-guide plate 5b, so that folding does not occur. Further, even if the paper sheet 1' is tilted greatly and the corner of the paper sheet 1' hits the sub-guide plate 5b, the sub-guide plate 5α is in a V-shape and will not easily break.

In addition, since the steps of the sub-guide plate 5b are designed to hold the paper sheets 1' at the step portions, the paper sheets can slip between the guide plate and the group of paper sheets, which was a problem in the conventional technology. Helps prevent

The configuration, operation, and effects of one embodiment of the present invention have been described above. In this embodiment, the main guide plate 5a
Although the buffer members 6 made of thin spring plates are provided on both sides of the paper sheet 1', the same effect can be obtained by providing buffer members made of an elastic material at the entire position where the paper sheet 1' contacts.

〔Effect of the invention〕

According to the present invention, it is possible to realize a paper sheet stacking apparatus that can stack paper sheets sent from a conveyance path into a storage box without causing damage such as scratches or folds to the front end of the paper sheets.
