Description

[Detailed explanation of the idea] The present invention relates to a paper discharge device for a sorter.

Conventionally, for example, a paper discharge tray used in a sorter or the like is tilted in the direction of paper discharge in a so-called one-first up position in order to neatly align the edges of discharged sheets and stack them in a stacked state. something is known.

That is, this structure has the advantage that the sheets discharged onto the paper discharge tray fall down to the base or lower part of the paper discharge tray due to gravity, and the edges are neatly aligned.

However, in the paper discharge tray having this structure, when handling relatively thin, stiff sheets or curled sheets, the leading edge of the sheet tends to curl or become cylindrical as the sheet is discharged.

In particular, this gap becomes a fatal problem when used with a device that aligns pages, such as a sorter, because it causes the pages to be out of order.

The present invention proposes a sheet discharge tray structure that takes advantage of the above-mentioned advantages of the inclined sheet discharge tray and also makes it possible to handle weak or curled sheets.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a sorter paper discharging device according to the present invention will be described with reference to the drawings.

In FIGS. 1 to 4, the sorter is equipped with a cart 1 that can be moved to any position, and a vertical support frame 2 is erected on the cart 1. .4.5, respectively, are installed.

The intake section transport device 3 includes a flat box-shaped base 6 whose base is supported by the support frame 2 .

The base 6, whose inclination angle can be adjusted by an adjustment mechanism (not shown) according to the height of the paper ejection port B of the copying machine A, has two pairs of boots J7 and 8 built-in, and these pulleys 7
．． An endless conveyor belt 9, a portion of which is exposed on the upper surface of the base 6, is stretched between the conveyor belts 8 and 8.

A plurality of support frames 11 that can be rotated around a shaft 10 (shown in the first figure) that is hung around the base 6 are arranged in parallel on the base 6 whose tip is tilted.

A plurality of rollers 12 are supported at the bottom of the support frame 11 and are rolled into contact with the upper surface of the conveyor belt 9. Therefore, the copy paper from the copying machine A taken into the intake section conveyance device 3 is transferred to the conveyor belt 9. 9 and rollers 12 and conveyed.

As shown in FIG. A deflection plate 13 for distributing the paper to the intake section conveyance device 3 or the paper discharge tray C is provided.

A deflection plate 13 that can tilt around the axis 14 of the base 6 as a fulcrum.
is placed in the position shown in phantom in FIG. 2 by a well-known electromagnetic solenoid or other mechanism energized by an interrupt signal from copier A and/or a sorter 'jam' emergency stop signal. I can be lifted up.

The copy paper conveyed by the intake section conveyance device 3 is transferred to the distribution section conveyance device 4 connected to the rear end of this intake section conveyance device 3.
will be taken over.

That is, the distribution unit conveyance device 4 is hung around pulleys 17 and 18 located above and below a mounting plate 16 that can be opened as shown by the imaginary line in FIG. It has an endless conveyor belt 19, and on the surface of these conveyor belts 190, horizontal shafts 20 (third
The paper ejecting roller 21 supported by the paper roller 21 in FIG.

In order to maintain the rolling contact state of these paper ejection rollers 21,
An auxiliary roller 22 located inside the conveyor belt 19 is attached to the attachment plate 16 in correspondence with the paper ejection roller 21 .

These auxiliary rollers 22 are each supported by shafts 25 that are stretched between grooves 24 of the frame body 23, as shown in FIG. The paper is pressed in the direction of the corresponding paper ejection roller 21 by the tensioned wires 27 that are alternately applied.

A paper discharge tray device 5 of the present invention, whose base portion is fixed to the support frame 2, is provided above the intake section conveyance device 3.

This paper ejection tray device 5 includes a plurality of paper ejection trays 28 whose bases are fixed to the support frame 2 in a state corresponding to each of the paper ejection rollers 21, but the detailed structure of the paper ejection trays 28 is This will be explained later with reference to FIG.

A gate member 29 is installed at the entrance of these discharge sheets [l1128].
(shown in the third figure) are located respectively.

These gate members 29 are fixed to a shaft 30 installed on the support frame 2, and can be operated by an electromagnetic solenoid 32 connected to a lever 31 provided at the shaft end of these bridges 0.

In other words, when one of these electromagnetic solenoids 32 is energized, the tip of the corresponding gate member 29 is advanced into the copy paper conveyance path consisting of the conveyance belt 19 and paper ejection roller 21, and is conveyed. The copied paper is discharged onto the corresponding paper discharge tray 28.

Note that FIG. 4 shows the drive section of the sorter mentioned above, and the timing belt 35, which is hung around the drive pulley 34 of the first drive motor 33 installed at the bottom of the support frame 2, is connected to the shaft of the pulley 8 mentioned above and the horizontal They are hung on driven pulleys 36 and 37 respectively fixed to the shaft ends of the shaft 15.

FIG. 5 is an enlarged view of the paper ejection [Tl128] according to the present invention, and this paper ejection tray 28 includes a plate-shaped paper ejection tray main body 28a that is inclined one tip upward with respect to the paper ejection direction. The base of the paper discharge tray main body 28a extends substantially horizontally, so that the leading edge of the copy paper being discharged does not lift up the previously collected copy paper.

The copy paper A is placed on the surface of the paper discharge tray main body 28a.
Two parallel protrusions 28b are formed extending in the discharge direction.

These protrusions 28b, whose number can be increased as needed, may be molded integrally with the sheet discharge tray main body 28a from resin or the like;
A protrusion made of a material with a small coefficient of friction is used as the sheet discharge plate main body 28a.
It may also be glued to.

However, the cross-sectional shape of these protrusions 28b is not limited to the illustrated rectangular shape, but may be semicircular, circular, triangular, or trapezoidal.

A suppressing member 39 whose base is suspended from a horizontal shaft 38 is positioned above the base of the paper discharging tray main body 28a, and the tip end 39a of this suppressing member 39 is connected to the discharging tray main body 28a between the protrusions 28b. close to the surface.

Although the illustrated pressing member 39 is a gravity type made of steel wire, it may be biased by a spring or the like.
Further, the pressing member 39 may be made of a flexible member.

Further, the distal end portion 39a of the suppressing member 39 may be brought into light contact with the surface of the sheet discharge tray body 28a.

Since the sheet discharge tray according to the present invention has the structure as described above, the leading edge of the sheet A discharged in the horizontal direction comes into contact with the protrusion 28b and the surface of the sheet discharge tray body 28a and forms a corrugated shape. It is discharged while its shape is corrected.

Therefore, even if the sheet is weak or curled, it is ejected along the surface of the paper ejection tray main body 28a due to the corrugated rigidity provided by the protrusions 28b.

In this case, if the pressing member 39 is attached, the sheet A
is reliably corrected into a wavy shape without floating up from the surface of the paper discharge tray main body 28a.

Note that when the sheet A is completely ejected onto the paper ejection tray, the sheet A will fall down due to gravity, and of course will come to rest with the rear end of the sheet stopped against the base of the paper ejection tray main body 28a. be.

After all, according to the present invention, equal resistance is applied to the left and right sides of the ejected sheet by the plurality of protrusions and the suppressing member located between them, so the simple structure allows curled sheets or weak sheets to be Even if there is a paper sheet, the sheet is ejected without tilting, and the completely ejected sheet slides down to the almost horizontal base of the paper ejection tray body, so that it is stacked neatly on the paper ejection tray body without being pushed up by subsequent sheets. It has the effect of being stored in.
