Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorter, which is an auxiliary equipment of a copying machine, for example, and particularly relates to the structure of a paper discharge tray device thereof.

Conventionally, the paper ejection tray used in sorters is used to neatly align the edges of ejected copy paper and keep it in a stacked state.
In order to reduce the occupied space and to prevent rapidly ejected copy paper from being ejected to the outside, it is sometimes tilted in the paper ejection direction in a so-called toe-up position.

That is, with such a toe-up structure, the copy paper discharged onto the paper discharge tray will fall to the base or lower part of the paper discharge tray due to gravity, and the edges of the copy paper will be automatically aligned.

However, in such a structure, the leading edge of the next copy paper that is ejected in a nearly horizontal direction by the paper ejection device immediately contacts the surface of the copy paper on the paper ejection tray, and the ejection force causes the leading edge of the next copy paper to be ejected into the paper ejection tray. The upper copy paper is pushed up and the desired edge alignment cannot be achieved.

This problem is particularly noticeable when handling thick and stiff copy paper, and in severe cases, the copy paper that is pushed up by the copy paper being ejected may fall off the paper output tray. .

For this reason, in the past, measures have been taken such as supporting the above-mentioned paper discharge tray in a movable state on a fixed part of the apparatus and widening the interval between the paper discharge trays in this portion when copy paper is discharged.

Therefore, in the conventional wandering paper tray device, a special device is required to widen the gap between the paper discharge trays, and the supporting structure of the paper discharge tray becomes complicated and unstable. The equipment has become larger and the price of the equipment has become relatively high.

The present invention proposes a paper discharge tray device for a sorter, which has a simple and improved structure and is capable of preventing copy paper from creeping up and properly discharging the copy paper.

Hereinafter, details of a sorter equipped with the paper discharge tray device of the present invention shown in the drawings will be explained.

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 .

Two pairs of pulleys 7 and 8 are built into the base 6, whose inclination angle can be adjusted by an adjustment mechanism (not shown) according to the height of the paper outlet B of the copying machine A. 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.

Then, on the base 6 whose tip is tilted, the base 6
A plurality of support frames 11 are arranged in parallel and are rotatable around a shaft 10 (shown in the first diagram) that is spanned between the support frames 11 .

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.

Further, as shown in FIG. 2, the copy paper discharged from the paper discharge port B is placed at the front end of the intake section conveying device 3 whose leading end is positioned on the paper discharge tray C of the copying machine A. Intake section conveyance device 3
Alternatively, a deflection plate 13 for distributing the paper to 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 lines in FIG. 2 by a well-known electromagnetic solenoid or other mechanism energized by an interrupt signal from copier A, a special paper copy signal, 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 suspended between pulleys 17 and 18 located above and below a mounting plate 16 that can be opened as shown by the imaginary line in FIG. The conveyor belts 19 have endless conveyor belts 19, and 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, auxiliary rollers 22 located inside the conveyor belt 19 are assembled to the mounting plate 16 in correspondence with the paper ejection rollers 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 whose base portion is fixed to the support frame 2 is provided above the intake section conveyance device 3 .

The paper discharge tray device 5 includes a plurality of paper discharge trays 28 whose bases are fixed to the support frame 2 in correspondence with the respective paper discharge rollers 21.

A gate member 29 (third
(as shown) are located respectively.

These gate members 29 are fixed to shafts 30 installed on the support frame 2, and can be operated by electromagnetic solenoids 32 coupled to levers 31 provided at the ends of these shafts 30.

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 constituted by the conveyance belt 19 and the paper discharge roller 21, The conveyed copy paper is discharged onto the corresponding paper discharge tray 28 as indicated by the dotted line arrow in FIG.

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 drive motor 33 installed at the lower part of the support frame 2, is connected to the shaft of the pulley 8 mentioned above and the above-mentioned drive pulley 34. Driven pools 36 respectively fixed to the shaft ends of the horizontal shaft 15. It can be multiplied by 37.

According to the present invention, the above-mentioned paper discharge tray 28 is constructed as follows.

That is, the features of the present invention are clearly shown in FIG. 2, in which each sheet discharge tray 28 has an inclined portion 28a that is raised upward in the direction of sheet discharge, and a passage connected to this inclined portion 28a. and a horizontal base 28b made integrally.

The horizontal base portion 28b extends substantially horizontally and has an arcuate portion 28C for smoothly communicating with the inclined portion 28a.
is formed and is connected to the inclined portion 28a.

Note that the reference numeral 28d in the illustrated example is a protrusion that straightens the weak copy paper into a wavy shape to give it rigidity, and these parallel protrusions 28d are used together with the pressing plate 28e.

Further, in the above embodiment, the upper end of the inclined portion 28a is exemplified as being inclined with respect to the horizontal plane, but the upper end may be in a substantially horizontal state.

Since the paper discharge tray device of the present invention has the structure described above,
The leading edge of copy paper discharged in an almost horizontal direction is at the horizontal base 2
8. The inclined portion 2 of the paper discharge tray 28 is located at a distance corresponding to the length of b.
8 Touch a.

Therefore, the copy paper being ejected is bent by a small force,
For this reason, even if there is previously ejected copy paper on the paper ejection tray 28, only a small frictional force acts between the ejected copy paper and the new copy paper, so the new copy paper is The copy paper can be loaded without pushing up the copy paper on the paper output tray 28.
The paper is discharged onto the paper discharge tray 28.

Of course, copy sheets are stacked on the paper ejection tray 28 by repeating such paper ejection movement, but the copy paper completely ejected onto the paper ejection tray 28 is deposited on the horizontal base 2 due to the tendency of the inclined portion 28a.
8b, and is stored on the paper discharge tray 28 in a neatly piled state.

As a result, according to the present invention, it is possible to obtain a paper discharge tray device for a sorter which prevents the phenomenon of stiff copy paper from rising up, with a simple structure.
