Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sheet sorting device having a sheet alignment function.

BACKGROUND OF THE INVENTION In recent years, there has been an increasing demand for sheet sorting devices used with copying machines to have not only a sheet sorting function but also a series of finishing functions such as bundling and perforation after sheet sorting.

An example of the conventional sheet sorting device described above will be described below with reference to the drawings.

FIG. 7 is a side view of the main parts of a conventional sheet sorting device, and FIG. 8 is a plan view thereof. In these figures, 1 is a copied sheet discharged from a copying machine, 2 is a main body of the sheet sorting device, 3 is a paper feed port for feeding the sheet 1, 4 is a paper discharge port for discharging the sheet 1, and 5a to 5f are a plurality of bins arranged in parallel for storing the sheets 1, each having a notch 6 formed on the side thereof. There is. 7 is a sheet aligning member; 8 is a rotating shaft for rotating the sheet aligning unit 7; 9 is a vertical guide formed in each bin to regulate the front side of the sheet; 10 is a sheet aligning member; A horizontal guide 11 is a conveyor belt that regulates the sides.

The operation of the sheet sorting device configured as described above will be described below.

When the copied sheet 1 discharged from the copying machine is fed into the bin 6& by the conveyor belt 11, its front side is placed in the bin 52.
They are aligned and stored in the vertical direction by contacting the L vertical guide 9. Subsequently, the rotating shaft 8 rotates, and the sheet aligning member 7 moves from position g to h as shown in FIG. Align the seats to complete the storage of the seats.

Problems to be Solved by the Invention However, in the above configuration, the sheet aligning member contacts the side edge of the sheet only at one point, and therefore, as shown in FIG. However, in the case of small size sheets, the edges are hit as shown by the dotted line, so they are stored diagonally, and all sizes of sheets are It wasn't enough to put together. Moreover, in the case of small-sized sheets, the operating distance of the sheet aligning member becomes large and the operating time becomes long. In addition, in conventional configurations, the sheets are aligned with the lateral guides for corner alignment, so in copiers that feed the sheets by centering them, the amount of lateral movement of the sheets increases, making the sheets more likely to tilt. It also has the problem of causing poor alignment.

In view of the above problems, the present invention provides a sheet sorting device that can reliably align all sheets of different sizes with a constant operation.

Means for Solving the Problems In order to solve the above problems, the sheet sorting device of the present invention includes a plurality of bins arranged in parallel for sorting and storing sheets;
The sheet alignment member includes a sheet alignment member that aligns the sheets in the bin by coming into contact with the side sides of the sheets stored in the bin, and a driving means that operates the sheet alignment member. It has a structure in which the sheets are aligned by contacting each other at certain points.

According to the above-described structure of the present invention, the side edges of the sheets discharged into the bin are pressed at multiple locations simultaneously by the sheet aligning member, so that the sheets are accurately aligned and stored in the bin without being skewed. Example 0 A sheet sorting device according to an example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of essential parts of a sheet sorting device according to an embodiment of the present invention. In the figure, 12 is the main body of the sheet sorting device, and 13ia to 13f are bins for storing sheets, which are arranged in parallel in a bin frame 14. It is set up. Bin 131L
A plurality of openings or notches 15a, . Sheet aligning section 6/ Material 16 is a support plate 1 integrally formed with rack 17 at the top and bottom.
It is supported by 8. A pinion gear 19 meshes with the racks 17 facing each other and is rotatably connected to a drive shaft 21 via a belt 2o. The drive shaft 21 is rotationally driven by a drive motor 23 via a worm gear 22 . 24 is a long hole formed in the upper bottle frame 14. FIG. 2 is a side configuration diagram of FIG. 1, and 25 is a wire that moves the bin frame 14, in which a plurality of bins are arranged in parallel, up and down by a drive control means (not shown); 26.27
28 and 29 are paper feed rollers, 28 and 29 are ejection rollers, 30 is a guide plate, 31 is a sheet, and 32 is a vertical guide formed on the bin.

The operation of the sheet sorting device configured as described above will be described below with reference to FIGS. 1 and 2. Copied sheets 31 discharged from a copying machine (not shown) are conveyed by paper feed rollers 26, 27 and discharge rollers 28, 29, and are discharged into bins 131L and 13b. Since the bin is sloped like an excavation, the rear end of the sheet abuts against a vertical guide 7 l -7 formed in the bin, so that the sheet is stored in alignment in the vertical direction. When one sheet is stored, a sensor (not shown) detects whether the sheet is stored or ejected, and drives the drive motor 23 to rotate. When the drive motor rotates, the drive shaft 21 and pinion gear 19 rotate, and the support plates 18 mutually swing in and out via the rack 17. Therefore, a plurality of sheet aligning members 16 have openings 16 &...
. . . It swings through the elongated hole 24 inside the IE5n and comes into contact with a plurality of places on both sides of the stored sheet to align and store the sheet at the center position in the sheet ejection direction. FIGS. 3 and 4 are front views of main parts showing this state.

Since the sheets 31 are simultaneously struck at two locations, front and rear, within the bin 13a, they are aligned without being skewed.

When hitting the side edges of the sheet with the sheet alignment member, as shown in FIG.
If the sheet aligning member 16 is biased in one direction, the contact pressure on the side of the sheet caused by the difference in rocking of the support plate 18 with respect to the sheet size can be absorbed, and the side of the sheet can be hit softly. This prevents bending and scratches.

FIG. 6 shows a plan view of a main part of another embodiment regarding the swinging of the sheet aligning member, in which numeral 36 is a dog-sized sheet and 36 is a small-sized sheet. In this embodiment, the size of the sheet conveyed by the copying machine is detected in advance by a detection means, and the drive motor 23 is driven by this detection signal, and when the sheet size is a dog-sized sheet 35, the sheet alignment member 16 is 1e
If the sheet size is small size sheet 36 at position j, move it to position 161 in advance and make it standby.0 This movement standby position will be a position a certain distance from the thick size sheet and the small size sheet. Therefore, when the dog-sized sheet 35 is discharged, the sheet aligning member 16 is moved to position 16j and is on standby, and when it is stored in the bin, it swings to position 16. .

Further, when a small size sheet 36 is discharged, the material 16 is moved to the position 161 in advance and is on standby, and when it is stored in the bin, it swings to the position 16m.

As described above, since the sheet alignment member is moved to a position corresponding to the sheet size in advance and is on standby, the sheet alignment operation can be performed in a constant motion regardless of the sheet size, and the sheets can be aligned in a short time.

In the above-described embodiment of the present invention, the sheet is aligned to the center position in the sheet feeding direction, but it is also possible to easily align only one side of the sheet to one side by swinging the sheet alignment member. The examples are not limited.

Effects of the Invention As detailed above, according to the present invention, the sheet alignment member contacts the side edges of the sheets stored in a plurality of bins arranged in parallel at a plurality of places to align the sheets. The side edges of the ejected sheets are pressed at multiple locations simultaneously by the sheet alignment member, so that they are accurately aligned and stored in the bin without being skewed. In addition, if the sheet alignment member is brought into contact with both sides of the sheet and the sheets are aligned at the center position of the sheet, it can be applied to a copying machine that feeds the sheet with the center aligned, and the sheets can be aligned in the lateral direction of the sheet. The amount of movement is also small, making it easy to align the sheets. Furthermore, by detecting the size of the sheets to be discharged into the bin and moving the sheet alignment member to a predetermined position corresponding to the sheet size and waiting, the operation to align the sheets can be performed in a constant manner regardless of the sheet size. There are many effects that can be achieved.
