Description

TECHNICAL FIELD The present invention relates to a sorter bin in a multi-stage sorter for collecting and stacking sheets discharged from a copying machine or the like.

(Prior Art) When a sheet discharged from a copying machine or the like has a plurality of pages and a plurality of copies, a multi-stage sorter is known which sorts and stacks the discharged sheets for each copy of each page. .

A type of this multi-stage sorter is configured to take out a laminated sheet discharged on a sorter bin having a sheet stacking surface in a direction orthogonal to the sheet discharging direction (usually the front side of a copying machine). There is a box-type multi-stage sorter. In this kind of multi-stage sorter, since the separation distance of each sorter bin is as narrow as several millimeters to several centimeters, in order to easily take out the sheet discharged on each sorter bin, the sorter bin is usually placed at an appropriate position on the sheet take-out side. A notch is formed so that a part of the discharged sheet faces the outside of the sheet stacking surface.

However, in the conventional sorter bin, when the size of the discharged sheet is considerably smaller than the sheet stacking surface, when the sheet is taken out, the discharged sheet is pushed into the back side of the sorter bin and it is difficult to take out the discharged sheet. There was a problem.

In addition, in the multi-stage sorter based on the sheet center, there is also a multi-stage sorter having a sheet shifting mechanism that allows the take-out portion of the discharged sheet side portion to be biased toward the side, but
There is a problem that the mechanism becomes complicated and the sheet conveyance reliability is lowered.

(Purpose) In a multi-stage sorter such as a sheet center reference, when ejecting a sheet smaller than the maximum size ejected on the sheet stacking surface, do not push the ejected sheet into the rear side of the sorter bin. An object of the present invention is to provide a sorter bin which can be reliably and easily taken out and has a simple structure.

(Structure) In the sorter bin according to the present invention, a sheet stopper for preventing the discharge sheet from moving inward of the sorter bin is formed at a position on the sheet stacking surface corresponding to the size of the discharge sheet along the sheet discharge direction. It is characterized by

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

Usually, a multi-stage sorter is provided with a plurality of sorter bins 1 arranged in multiple stages as shown in FIG. 1, for example, and is fed from a manual feed table 2 or a sheet discharge port of a copying machine (not shown) or the like. The sheet S is guided toward each sorter bin 1 through a horizontal transport unit 3 including a guide plate and a pair of transport rollers and a branch guide plate 4.

The sheet S conveyed toward each sorter bin 1 has, for example, a conveying roller 5a and a driven roller 5 as shown in FIG.
Sheets are discharged onto the sorter bin 1 designated in advance by the sheet collating means 5 including the discharge roller 5c, the deflection claw 5d, the deflection lever 5e, and the bin solenoid 5f. That is,
As shown in the sheet collating means 5 in the upper part of FIG. 2, the sheet S is turned on by the bin solenoid 5f, and the deflecting claw 5d is swung via the deflecting lever 5e. S
The sheet S is discharged onto the sorter bin 1 corresponding to the sheet collating means 5 by extending the inside of the conveying path and the course of the sheet S is deflected. The sheets are collated by being discharged onto the next-stage sorter bin 1 through the next-stage sheet collating means 5 which operates in the same manner.

The sorter bin 1 has a sheet stacking surface 1a for stacking the sheets S discharged through the sheet collating means 5 as shown in FIG. 3, for example.
Each of the sheet carrying-in side of 1a and the inner side of the multi-stage sorter has a wall portion for preventing the discharged sheet S from falling off.
1b and 1c are formed respectively. In addition, a notch 1d for facilitating the taking-out of the stacked sheets S is provided on the front side of the multi-stage sorter facing the back wall 1c of the multi-stage sorter, that is, the side of the sheet S in the take-out direction a side. Has been formed.

On the other hand, a sheet stopper 1e is formed at an appropriate position on the sheet stacking surface 1a.

The sheet stopper 1e is substantially parallel to the discharge direction b of the sheet S and is smaller in size than the maximum size sheet discharged onto the sheet stacking surface 1a (for example, the smallest size sheet that can be conveyed by a multi-stage sorter). ) Is formed on the sheet stacking surface close to the side edge Sa on the back side of the sorter.

Further, the sheet stopper 1e is formed at a height lower than the height of the sheet S discharging portion, that is, the height of the sheet carrying-in side wall portion 1b.

The sorter bin 1 configured as described above is a sheet stacking surface.
When the sheet S discharged onto the multi-stage sorter and having a part of the side edge Sb on the front side of the multi-stage sorter facing the notch 1d is accidentally pushed to the back side of the multi-stage sorter, the back side of the sheet S The edge Sa comes into contact with the sheet stopper 1e to prevent the sheet S from moving inward.

In the illustrated sheet stopper 1e, as shown in FIG. 4, for example, the stopper surface where the notch 1d is located, that is, the surface facing the side edge of the discharged sheet S on the back side of the multi-stage sorter is the sheet. It is formed so as to be perpendicular to the loading surface 1a. The stopper surface thus formed causes the side edge Sa on the back side of the sheet S to move toward the sheet stopper 1e when the discharged sheet S is accidentally pushed to the back side of the sorter bin 1.
It is effective to prevent the vehicle from overcoming and moving to the inner side of the sorter bin 1.

The sorter bin 1 according to the present invention has a number of sheet stoppers 1e corresponding to the type of sheets S discharged to the multi-stage sorter.
May be formed at a position corresponding to the size of each sheet S. Further, the sheet stopper 1e may be integral with or separate from the sorter bin 1.

(Effects) The sorter bin according to the present invention has a simple structure, and in a multi-stage sorter such as a sheet center reference, when taking out a sheet of a size smaller than the maximum size sheet discharged to the sheet stacking surface, the side edge of the sheet is Since it comes into contact with the sheet stopper, the sheet can be taken out reliably and easily without pushing it into the sorter bin.
