Abstract

PURPOSE:To store sheets fed from an inlet in bins sequentially by turning a longitudinal shaft only in an angle with the adjacent bin by one action of a sheet direction changing mechanism. CONSTITUTION:In a designated time later after a limit switch or the like detects that a sheet is fed into an inlet 11, a solenoid of a sheet direction changing mechanism 18 is excited to turn a finger 19 around a bin 21 to the vertical position. At this time, a ratchet wheel 22 is rotated in a designated degree of arc by a click piece, and the rotation is transmitted through a shaft 23, bevel gears 24, 25, a pulley 26, a belt 27 and a pulley 28 to a longitudinal shaft 12, so that the longitudinal shaft 12 is rotated only in an angle with the adjacent bin 14. By this rotation, a finger 19 is opposed to a bin 14 adjacent to a bin 14 where a sheet is previously stored to lengthwise store the sheet having the leading edge placed on the finger 19 in the empty bin 14.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sorter that sequentially stores sheets ejected from a copying machine or the like into a plurality of pins and aligns the pages.

BACKGROUND TECHNOLOGY - A sorter in which a plurality of pins are arranged at intervals in the vertical direction, and sheets are sequentially stored in the pins to align the pages.

Problems to be Solved by the Invention Since the pins are arranged in the vertical direction, when taking out the paper from the lower pin, it is necessary to bend at the waist and take out the paper. It is easy to take out and easy to remove.

Means and Effect for Solving Problems A plurality of pins each having a vertically elongated space are provided radially around the center of the vertical axis, and a paper orientation conversion mechanism is provided between the pins and the paper inlet to change the paper orientation to portrait. is provided, and when this sheet orientation conversion mechanism operates once, the vertical axis rotates by the angle between adjacent pins, so that the sheets fed from the entrance can be sequentially stored on the pins.68 Embodiment - Figure 1 is a schematic front view. A sorter B is installed adjacent to the copying machine, and inside the copying machine main body there are a photoreceptor 2, a paper feed mechanism 3, a transport mechanism 4, and a fixing device 5. etc. are arranged next to each other, the paper is copied by a conventionally known copying process, and the paper is transferred to the entrance II of the sorter body 10 by the transport roller 6.
is discharged.

A vertical shaft 12 is rotatably supported in the sorter body 10 by a bearing 13, and a plurality of pins 14 are radially fixed to the vertical shaft 12, and the pins 14 are connected to a pair of vertical plates 15, 15 and a bottom plate. 16, the space 17 is long in the vertical direction, closed at the bottom, and open at the top and sides.

A paper orientation changing mechanism 1 is provided between the pin 14 and the entrance 11.
8 is provided, this paper orientation conversion mechanism! 8 includes a finger 19 and a solenoid 20. The finger 19 is rotatably supported in a horizontal position and a vertical position by a pin 21, and a solenoid 20 is pivotally connected to the base 19α.

As shown in FIG. 2, a ratchet wheel 22 is rotatably supported by a shaft 23 below the finger base 19α.
In addition, the shaft 23 is engaged with the claw piece 29 provided at
It is connected to the vertical axis 12 via g.

30 is a stopper of the ratchet wheel 22 and is moved in and out by a solenoid 31.

Reference numeral 32 denotes a screw that urges the vertical shaft 12 to rotate in one direction.

Next, the operation will be explained.

After a predetermined time has elapsed after a limit switch (not shown) detects that paper has been fed into the inlet 11, the solenoid 2
0 is energized to rotate the finger 19 about the pin 21 to a vertical position.

As a result, the paper whose leading edge is placed on the finger I9 is conveyed vertically into the space 17 of the sorter 14 and stored therein.

At this time, when the finger 19 rotates to the vertical position, the claw piece 2
The ratchet wheel 22 is rotated by a predetermined rotation angle by the shaft 23, the bevel gears 24, 25, and the pulley 2.
6. The belt 27-% is transmitted to the vertical shaft 12 through the pulley 28 to rotate the vertical shaft 12 by the angle between the adjacent pins 14.

Because of this, when the finger 19 rotates to the vertical position, the pin 14 adjacent to the pin 14 that previously stored the paper
faces the finger 19, and the paper is stored in the pin 14.

After paper storage is completed, the solenoid 20 is demagnetized and the finger 19 is placed in a horizontal position. At this time, the claw piece 29 slides against the ratchet wheel 22, and the slot flange 3
Since the rotation is locked at 0, the ratchet wheel 22
does not rotate.

By repeating the above operations, sheets can be sequentially stored in the pinot 14 and the pages can be aligned.

Note that since the bottom wall 16 of the pin 14 is shown obliquely, the pins 14 are sequentially stored on either side of the vertical wall 5.

When the copying operation for the required number of sheets is completed, the solenoid 31 is energized by a signal from the copying machine main body 1, and the stopper 30 is released from the ratchet wheel 22.

As a result, the vertical shaft 12 is rotated and returned to the initial position by the spring force of the spring 32, and this is detected by some means, the solenoid 31 is demagnetized, and the ratchet wheel 22 is locked with the stopper 30.

When the rotor 1 and the vertical shaft 12 are rotated in one direction by the rotation of the finger 19 to the vertical position, the nokune 32 is deflected and the rotational force in the other direction is stored, and the rotational force is transferred to the ratchet wheel 22 by the stopper 30. It is held by a rotation lock in the other direction.

Effects of the Invention Since the pins 4 having the vertically elongated spaces 17 are arranged radially, the pins 14 are not at the same height, making it easy to take out the paper from the pins 14.

Since one operation of the sheet orientation changing mechanism 18 rotates the vertical shaft 12 by the angle between adjacent pins 14, 14, sheets fed through the inlet 11 can be stored in the pins 14 one after another.
