Abstract

PURPOSE:To finely arrange paper sheets by installing a member which projects nearly flush with the surface of a fixed guide on both side parts of a movable guide, in a mechanism for arranging the edge surfaces of the paper sheets stacked on a table which can be moved vertically. CONSTITUTION:Two guide pins 15 are projectingly installed on a fixed guide 11, and the members 13 and 13 which project nearly flush with the surface 11b of the fixed guide and two elliptical holes 16 fitted with the guide pins 15 are provided on both edge parts of a movable guide 12. The movable guide 12 is supported in vertically movable manner, on the fixed guide 11 by the fitting between the pin holes and pins. One edge of each spring 14 is engaged with each engagingly locking pin 18 through each pulley 17 supported by each guide pin 15, and the other edge is engagingly locked with each engagingly locking pin 19, and the movable guide 12 always comes in contact with a fixed wall surface 5. The edge surfaces of the paper sheets 100 which are sent in the direction of arrow B to the under part of the fixed wall surface 5 and stacked on a table 4 are engaging locked with a paper arranging mechanism 10, and neatly arranged.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a stack paper alignment mechanism that aligns the edges of paper sheets that have been processed by a printer, etc., are ejected, sent below a fixed wall surface, and stacked on a vertically movable table. In order to ensure that the sheets are neatly aligned, there is a fixed guide fixed to a vertically movable table provided below a fixed wall, and a fixed guide provided movably vertically in contact with the back surface of the fixed guide. , a movable guide which is urged upward by an urging means provided between the fixed part and comes into contact with the fixed wall surface, and the movable guide is configured to move the sheets of paper sent below the fixed wall surface and stacked on the table. In the stack paper alignment mechanism for aligning end faces, members are provided on both sides of the movable guide to protrude substantially flush with the surface of the fixed guide.

[Industrial application field]

The present invention relates to a stack paper alignment mechanism that aligns the end faces of paper sheets that have been processed by a printer or the like and are discharged, sent below a fixed wall surface, and stacked on a vertically movable table.

[Conventional technology]

FIG. 4 is a perspective view showing the general structure of a conventional stack paper alignment mechanism 1. The stack paper alignment mechanism 1 is composed of a fixed guide 2 and a movable guide 3. As shown in FIG.

The fixed guide 2 is fixed on a vertically movable table 4.

The movable guide 3 is provided so as to be movable up and down in contact with the back surface of the fixed guide 2, and is biased by a spring (not shown) provided between the movable guide 3 and the fixed guide 2 so that its upper end 3a is always aligned with the fixed wall surface 5.
It is designed to come into contact with.

The sheets are sent below the fixed wall surface 5 and stacked on the table 4. At this time, the stacked sheet alignment mechanism 1 locks the end surface (front or side) of the sheets to be stacked and aligns the end surface. Plays the role of aligning. The table 4 is raised at the beginning of stacking, but lowers as the stacked sheets become higher.

[Problem to be solved by the invention]

However, in the conventional structure as described above, when the stacked sheets become higher than the fixed guide 2, the end surfaces of the sheets 100 are then locked by the movable guide 3 as shown in FIG. That is, a step is formed between the fixed guide 2 and the movable guide 3 on the end surface of the sheets to be aligned, and the sheets are not neatly aligned.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stack paper alignment mechanism that can neatly align paper sheets.

[Means to solve the problem]

FIG. 1 is an explanatory diagram of the principle of the present invention, and in the figure, 11 is a fixed guide and 12 is a movable guide. Note that the same reference numerals are used for members that are common to the conventional one.

The fixed guide 11 is fixed to a table 4 which is provided below the fixed wall surface 5 and is movable up and down.

The movable guide 12 is provided so as to be movable up and down in contact with the back surface 11a of the fixed guide 11, and is urged upward by an urging means (not shown) provided between the movable guide 12 and the fixed guide 11, so that the upper end 12a is fixed. It comes into contact with the wall surface 5. On both sides of the movable guide 12, members 13 are provided that protrude substantially flush with the surface 11b of the fixed guide 11 (either flush with the surface 11b or slightly recessed).

[For production]

At the beginning of the paper stack, the table 4 is raised;
The front end surface of the paper 100 that is sent below the fixed wall surface 5 in the direction of arrow A and is stacked on the table 4 is fixed to the fixed guide 11.
0 surface 11b.

Table 4 descends as the stack progresses.

Then, when the height of the stacked sheets 100 is higher than the fixed guide 11, the front end surface of the sheet 100 is locked to the end surface 13a of the member 13.
1a, there is no difference in level between the fixed guide 11 and the movable guide 12, which has been a problem in the past.

Although FIG. 1 shows an example in which the front edges of the sheets are aligned, it can also be used to align the side edges of the sheets.

〔Example〕

The present invention will now be described in detail with reference to FIGS. 2 and 3.

FIG. 2 is a perspective view showing the structure of the stack paper alignment mechanism 10 of this example. In the figure, 14 is a spring (energizing means), and the same reference numerals are used for the same members as in FIG. 1. Also,
The member 13 may be formed by bending both ends of a plate member constituting the movable guide 12, or may be formed by integrating separate members by gluing, screwing, or other means.

The movable guide 12 is supported by the fixed guide 11 so as to be vertically movable, and the details of the structure thereof are as follows.

Two guide pins 15 are provided protruding from the fixed guide 11.
The movable guide 12 is provided with two vertically extending elongated holes 16 into which each guide bin 15 is fitted. By fitting the pin and the hole, the movable guide 12 is supported by the fixed guide 11 so as to be vertically movable.

The procedure for fixing the guide pin 15 is as shown in FIG.

The spring 14 is wound around half the circumference of the boot I717, which is rotatably supported by the guide pin 15, and has one end locked to a locking pin 18 protruding from the fixed guide 11, and the other end to the movable guide 12. It is locked to a protruding locking pin 19. Therefore, the movable guide 12 is urged upward by the spring 14 and is always in contact with the fixed wall surface 5 (regardless of the vertical position of the table 4).

The operation of the stack paper alignment mechanism 10 having such a configuration is as described above in connection with FIG. 1, and as shown in FIG. The end faces of the paper sheets 100 to be stacked are engaged with the stack paper alignment mechanism 10 and aligned. In this case, the step difference in the end surface of the paper between the fixed guide 11 and the movable guide 12, which has been a problem in the past, is eliminated, and the paper is neatly aligned.

Although FIG. 2 shows an example of aligning the side edge surfaces of the sheets 100, it is of course possible to use the method to align the front edge surfaces of the sheets.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to eliminate the level difference between the fixed guide and the movable guide and to neatly align the sheets.
