Abstract

PURPOSE:To perform stabilized stacking in a stacker for processed individual sheet papers by adjusting the stacker table height in upward or downward movement linked with the downward or upward movement of a storage table of an adjustment mechanism. CONSTITUTION:A paper sheet 2 from a paper feed mechanism 16 undergoes necessary processing in a paper processing unit 7 and the processed paper sheet 8 is transferred with a paper transfer mechanism 6 to a stacker table 17. The stacker table 17 linked to a required position of farther side of a vertically movable chain 13 goes down by the same amount with the ascent amount of a storage table 11 corresponding to thickness of the fed out paper sheets by means of an adjustment mechanism 14. Thus, since the top level of the processed paper sheet 8 put on the stacker table 11 is kept nearly constant and the inflow angle of the processed paper sheet 8 against the table 17 is nearly constant regardless of the paper length L, stabilized stacking of the processed paper sheet 8 can be continued.

Description

[Detailed Description of the Invention] [Summary] A stacker table is provided so as to be interlocked with a mechanism that raises the hopper table in accordance with the amount of paper stacked on the hopper table to be fed out, and the stacker table is provided to be linked to a mechanism that raises the hopper table by a distance corresponding to the lifting distance. By lowering the stacker table, the angle at which processed sheets flow into the stacking port is maintained constant, allowing stable stacking.

C. Field of Industrial Application] The present invention relates to a stacker for processed cut sheets, and more particularly to a stacker structure interlocking with a hopper table.

[Conventional technology]

FIG. 2 shows a general mechanical diagram of a conventional paper feeding mechanism and stacker. In the figure, 1 is a paper feeding mechanism, which includes a hopper table 3 on which paper 2 is loaded and a roller 4 that feeds paper 2.
and an elevating mechanism 5 that controls the height of the hopper table 3 in accordance with the second feed amount of paper on the hopper table 3.

As the paper 2 is fed out one by one by the roller 4 from the top surface of the paper 2 stacked on the hopper table 3 and the paper 2 decreases, the gap between the roller 4 and the top surface of the paper 2 becomes thicker. Upon detection, the elevating mechanism 5 is driven and controlled to maintain the contact level between the roller 4 and the upper surface of the paper 2.

The paper 2 fed out by the roller 4 is transported by a paper feed mechanism 6, and is subjected to printing and other processing in a paper processing section 7, and the processed paper 8 is stacked on a fixed stacker 9 by the paper feed mechanism 6.

In this case, the stacker 9 is often of a stacking type in which the processed sheets 8 are simply stacked one after another.

[Problem that the invention seeks to solve]

FIG. 3 shows a mechanical diagram for explaining the drawbacks of the conventional stacker. In the figure, L indicates the length of the processed paper 8 in the paper feeding direction, and H indicates the depth of the paper stacking section of the stacker 9.

If the length is short compared to the depth H and the amount of paper loaded is large, there is a drawback that troubles such as the processed paper 8 stopping vertically or misalignment occur as shown in the figure.

The present invention was created in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide a paper stacker that can always stably stack paper regardless of its length.

[Means for solving the problem] As shown in FIG. 1, the paper stacker of the present invention adjusts the vertical height of the hopper table 11 in accordance with the amount of paper 2 stacked on the hopper table 11. The stacker table 17 is connected to the adjustment mechanism 14, and the vertical height of the stacker table 17 is adjusted by the adjustment mechanism 14.

[Effect]

The adjustment mechanism 14 includes, for example, two chain gears 12 and an endless chain 13 meshing with the chain gears 12.
By rotating the chain gear 12 in accordance with the amount of paper 2 fed out on the hopper table 11 attached to a predetermined position 15 of the chain 13, the contact level between the upper surface of the paper 2 and the roller 4 is adjusted. I do.

At the same time, the stacker table 17 attached to the required position 18 of the chain 13 is lowered by the amount of rise of the hopper table 11, and the inflow angle of the inflowing processed paper 8 is kept constant, regardless of the length of the paper. Ensures stable loading.

〔Example〕

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

In order to make the explanation of the configuration and operation easier to understand, the same parts are denoted by the same reference numerals throughout the drawings, and repeated explanation thereof will be omitted.

FIG. 1 shows a mechanical diagram of the stunning force according to an embodiment of the present invention. In the figure, reference numeral 16 denotes a paper feeding mechanism, which includes a hopper table 11 for loading the paper 2, a roller 4 for feeding out the paper 2, and a height of the hopper table 11 corresponding to the amount of feeding of the paper 2 on the hopper table 11. It is composed of an adjustment mechanism 14 that controls the control.

The adjustment mechanism 14 includes, for example, two chain gears 12 and an endless chain 13 meshing with each chain gear 12.
It consists of A hopper table 11 is placed at a predetermined position 15 on one side of the chain 13 across the chain gear 12.
are connected. The chain gear 12 is rotated in accordance with the amount of paper 2 fed out on the hopper table 11, and moves the position 15 of the chain 13 in the direction of arrow U, thereby adjusting the level of contact between the upper surface of the paper 2 and the roller 4. .

The paper 2 fed out from the paper feed mechanism 16 is subjected to the necessary processing in the paper processing section 7, and the processed paper 8 is
; conveyed to the stacker table 17 by the feeding mechanism 6;

The stacker table 17 is connected to a predetermined position 18 of the other chain 13 that is vertically movable, and is lowered in conjunction with the movement of the chain 13 in the direction of the arrow by the amount of rise of the hopper table 1.

Due to this interlocking lowering, the upper surface level of the processed paper 8 stacked on the stacker table 17 remains at a constant position, and the inflow angle of the processed paper 8 into the stacker table 17 is maintained regardless of the length of the paper. Since it is approximately constant, it is possible to continue stably loading the processed sheets 8.

In addition, in the above embodiment, the adjustment mechanism 14 is connected to the chain gear 1.
2 and the chain 13, but the present invention is not limited to this, and a combination of a normal pulley and a belt may be used.

Furthermore, although the present embodiment has been described with respect to single-sheet paper, it is also possible to use continuous form paper.

〔Effect of the invention〕

As described above in detail, according to the paper stacker of the present invention, it is possible to stably stack processed paper sheets continuously.
