[Industrial application field]

The present invention relates to a paper post-processing mechanism connected to a printer device.

In particular, printers for computer-based newspaper typesetting systems often print a single article on multiple sheets, and newspaper companies operate post-processing equipment that binds the multiple sheets as a set with staplers. . The number of sheets to be bound varies over a wide range from 2 to 20 sheets, but for any number of sheets to be bound, a post-processing mechanism is required for the printer to ensure that designated areas other than article printing are finely detailed and output multiple sheets of paper as a set. It is said that

[Conventional technology]

The post-processing mechanism of conventionally widely used printer devices is
As shown in FIG. 6, a tray 3 of a size that can stack printed sheets 12, e.g., A4 size, is disposed in the paper conveyance direction, that is, in the direction of arrow A, of the conveyance roller 2 suspended horizontally on the output side of the printer. , a shutter 4 that moves in the direction of arrow BC by a drive device (not shown) on the discharge side end surface of the tray 3;
A pair of discharge rollers 5 are provided in parallel on the conveyance roller 2 side at a constant interval, and a stapler is installed between the discharge rollers 5 and the shutter 4 so as to staple the left side of the starting edge of the paper 1 in the conveyance direction.
6 are arranged.

When the plural sheets of paper 1 printed by the printer are conveyed one by one in the direction of arrow A by the conveyance roller 2, the paper 1
When the sheets 1 hit the shutter 4 that closes the discharge side of the receiving tray 3 and are stacked inside the receiving tray 3, and the stacked sheets 1 are driven to the stacked sheets 1, the stacked sheets 1 are moved to the opposite holder 6-1 as shown in FIG. The claw 6-2 provided on the inside rotates by a certain angle in the direction of the arrow to form a certain length of wire 7 held by a grip (not shown) into a mouth shape, and the bent part is attached to the holder 6. -1 opposing guide groove 6-1a
rises in the direction of arrow F and is self-held at the position shown by the dotted line by the elasticity of the wire 7.

Next, the holder 6-1 is lowered in the direction of the arrow E to press the end surface against the stacked sheets of sheets 6 to 4, and then the driver 6-3 is lowered to press the front end surface against the paper l. The mouth-shaped wire 7 descends accordingly, and its bent portion passes through the paper l and is bent inward by the bending guide 6-48 of the pedestal 6-4 to weave the paper.

Thereafter, when the shutter 4 shown in FIG. 6 is opened, a pair of ejection rollers 5 are rotated to sandwich the bound sheets 1 and eject them from the tray 3.

[Problem that the invention seeks to solve]

The problem with the conventional post-processing mechanism described above is that the multiple sheets of printed paper are successively brought against the shutter by a conveyance roller and stacked inside the tray, and the complicated mechanism shown in FIG. The machine drives the left side starting edge of the paper with a wire parallel to the starting edge surface, so the mechanical operation of the stabilizer is unstable, so it is possible to scrutinize the part where the article was printed with uneven paper. A problem has arisen in which the parts that are off the paper are bound.

In view of the above problems, the present invention aims to provide a post-processing mechanism for a printer device that reliably binds and discharges a plurality of printed sheets at designated positions.

A means 9 for detecting the starting edge and the ending edge of the paper 1, for example, a sensor 15, is disposed facing the roller 2 and is connected to the upper conveying roller I.
3, the paper 10 is placed close to the side where the paper 10 is bitten. saucer 3
is a pressing means 9 that presses the adhesive 11 facing the adhesive 11 applied to the paper 1 by the adhesive member supply mechanism 12;
For example, the button 14 and the shutter 4 for opening and closing the discharge side of the tray 3 are arranged to move in the vertical direction.

Then, the sensor 15 detects the starting edge of each sheet 1 other than the top layer to be stacked, and based on the signal, a control circuit (not shown) drives the adhesive member supply mechanism 12 to supply the adhesive tape 11 shown in FIG. As shown in FIG. 4, the release tape 11-2 on the paper 1 side is peeled off to move the adhesive member 11-1 to the outer periphery of the supply section 12-1c, and the adhesive member supply mechanism 12 is moved in the direction of arrow F. The adhesive member 11 moved to the supply unit 12-IC by synchronizing the supply unit 12-1c with the adhesive member supply position of the paper 1 which is rotated and conveyed.
-1 to the paper 1, the adhesive member 11-1 is placed at a predetermined position, and the uppermost paper 1 to be laminated with the supplied paper 1 is stacked inside the tray 3, and the pusher 14 is moved. It is configured to bind the stacked sheets 1 by pressing the adhesive member 11-1.

[Effect]

In the present invention, by controlling the adhesive member supply mechanism 12 with a control circuit, each sheet of paper 1 other than the top layer to be stacked is
