Abstract

PURPOSE:To reduce the dimension of the captioned apparatus by installing a mechanism for assorting paper sheets by shifting a stacker table in parallel to the direction perpendicular to the output direction of the paper sheet onto a stacker part of a printer for the printing onto a cut sheet or a continuous cutting machine. CONSTITUTION:A plate metal 24 in U-form installed onto the under-surface of a stacker table 12, and the outside plate (a) of a slide guide 25 is fixed onto the both side surfaces, and an inside plate (b) is fixed onto a metal fitting 27 installed onto a board 26, and the stacker table 12 is made shiftable in parallel. The plate metal 24 is driven in parallel by a link mechanism 28 by driving a motor 29 installed onto the board 26 through a metal fitting 30. The stacker is equipped with a printer for the printing onto a cut sheet or a continuous paper cutting apparatus 1, and the stacker table 12 is shifted in parallel to the direction B perpendicular to the output direction a of the paper, an the cut sheets 13 are piled and are shifted according to the job unit or sending destination, and thus work is facilitated. Further, the installation space can be reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention shifts continuously produced cut sheets by job or by destination of the cut sheets to make it easier for workers to sort and box them. This invention relates to a stacker paper sorting mechanism.

2. Description of the Related Art Conventionally, for example, there is a printing apparatus 1 as shown in FIG. 3, which includes a continuous cutting device 2 and a stacker section 3 for stacking printed sheets.

The printing device 1 rotates a photosensitive drum 4, charges it with a charger 5, exposes it with an exposure optical system 6 to form a latent image, visualizes it with a developer 7, and transfers it to a paper feed section with a transfer device 8. 9, the transferred image is fixed and outputted by a fixing device 11, and sent to a continuous paper cutting device 2, where the continuous paper is cut page by page, stored in a stacker section 3, and processed. .

In the stacker section 3, it is necessary to sort the continuously appearing cut sheets by job or by the destination of the cut sheets to facilitate classification processing.

[Conventional technology]

A conventional method for sorting paper in a stacker is to rotate the stacker table to shift the stack position and sort the paper into sections.

FIG. 4 is a perspective view of a mechanism for rotating the stacker table. In the figure, reference numeral 12 denotes a stacker table, and three belts 13 rotating on the stacker table 12 are exposed and convey the cut sheets 13 that come out in succession. A stopper 22 is provided at the rear of the stacker table 12, and the force/gutter sheets 13 conveyed by the stopper 22 are stacked. Belt 13 inside stacker table 12
It has a built-in pulley (not shown) that drives the
There is a motor 14 on the side that drives the pulley. Also, the mechanism for rotating the stacker table 12 is the stacker table 12.
A link mechanism 15 is attached to the stacker table 15, a motor 16 for driving the link mechanism 15 is attached to the stand 17 via a metal fitting 18, and a roller 19 is provided on the lower surface of the stacker table 12.
The stacker table 12 is rotated around a shaft 21 (fixed to the base 17) that engages with the roller 19 and is provided with a rail 20 on the base 17, and supports the stacker table 12 via an arm 23 by driving the link mechanism 15. rotates.

[Problems to be Solved by the Invention] The conventional method of shifting the stacking position by rotating the stacker table 12 is to move the stacker table 12 around a shaft 21 via an arm 23 as shown in FIG. Because it rotates, it travels a long distance (
(double the length of the stacker table 12) is required. Therefore, there is a problem in that the structure is large, which is disadvantageous in terms of reducing the size of the device space.

[Means for solving problems]

The problem described above is that the stacker table is equipped with a paper conveyance belt and a stopper for stacking the conveyed paper, and a mechanism that moves the table parallel to the paper output direction of the printer or continuous paper cutting device in a direction perpendicular to the paper output direction. This problem is solved by the paper sorting mechanism of the stacker of the present invention, which is provided and separates the paper sheets.

[Effect]

That is, the stacker section is provided with a stacker table that moves in parallel to the paper output direction of the printer or continuous paper cutting device, and continuously output cut sheets are separated by job or by destination of the cut sheets. By moving the stacker table in parallel to stack and sort paper, it is easier for the operator to sort and box. This mechanism for moving the stacker table in parallel does not require rotating the stacker table via an arm as in the prior art, and therefore only requires a distance equal to the length of the stacker table, so the space is small.

〔Example〕

Hereinafter, the gist of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention, and FIG. 2 is a plan view of the present invention applied to a continuous paper cutting device.

Furthermore, throughout the plan, common symbols are the same object.

In the figure, the stacker table 12 has three belts 13 rotating on the stacker table 12, as in the conventional case.
is exposed and the cut sheets 13 that come out continuously are conveyed. A stopper 22 is provided at the rear of the stacker table 12, and the cut sheets 13 conveyed by the stopper 22 are stacked. A pulley (not shown) for driving a belt 13 is built into the stacker table 12, and a motor 14 for driving the pulley is provided on the side.

In order to move the stacker table 12 in parallel, a U-shaped metal plate 24 is attached to the lower surface of the stacker table 12, and the outer plate a of the slide guide 25 is attached to both sides of the metal plate 24.
is fixed, the inner plate of the slide guide 25 is attached to the stand 26 and fixed to the metal fittings 27, and the stacker table 12 is fixed.

The motor 29 that drives the link mechanism 28 is attached to the bracket 3 on the stand 26.
0, and the stacker table 12 is moved in parallel by driving the link mechanism 28. The slide guide 25 has a structure in which a ball is built in between the outer plate a and the inner plate so that the inner plate slides smoothly, and is commercially available.

By adopting the structure in which the stacker table 12 is moved in parallel as described above, there is no need to rotate the stacker table via an arm as in the conventional case, so the distance is only the length of the stacker table 12, so the space is small and the equipment is downsized.

The stacker of the present invention is provided in a printer or continuous paper cutting device 1 that prints on cut sheets as shown in FIG.
Move in parallel. For example, if the continuously outputted cut sheets 13 are staggered and piled up by job or by destination of the cut sheets 13, there is an advantage that it becomes easier for the operator to sort and box the cut sheets 13.

〔Effect of the invention〕

As described above, according to the present invention, the stacker section of a printer that prints on cut sheets or a continuous paper cutting device is provided with a mechanism that moves a table parallel to the paper output direction in a direction perpendicular to the paper output direction to sort the paper. Since the distance is the same as the length of the table, the device is compact and the space required for the device can be reduced.
