Abstract

PURPOSE:To increase the number of sheets to be accommodated by using the paper-inlet side end part of a specified bin as the axis and enabling the opposite end part to be vertically moved when accommodating sheets of Z-form folded paper. CONSTITUTION:When sheets of Z-form folded paper are sorted, a solenoid 27 is operated causing an arm 25 to rotate counterclockwise. A wire 23 is moved downward, bins 20b1 to 20b4 are rotated clockwise centering around pivots 22b1 to 22b4, and an interval formed between each of bins 20a1 to 20a4 and each of the bins 20b1 to 20b4 is made narrower on the side of a conveying belt 2 while made wider on the side of the wire 23. The Z-form folded bulky parts of the sheets of paper are housed in a space with a larger interval formed between each of the bins 20a1 to 20a4 and each of the bins 20b1 to 20b4. Thereby, the number of sheets of Z-form folded paper to be accommodated can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a sorter, and particularly to a sorter suitable for storing captured sheets.

(Prior Art) FIG. 1 shows an example of a conventional sorter. Further, FIG. 2 shows a front view of the paper sorting mechanism.

The sheets that have been copied are sent to the sorter entrance 1. The paper that has passed through the entrance 1 is attracted to the conveyor belt 2,
As the conveyor belt 2 rotates clockwise, it is conveyed from the top to the bottom in the figure. Note that the paper is attracted to the conveyor belt 2 because a suction tank 3 is provided inside the conveyor belt 2 and communicates with a hole drilled in the conveyor belt 2.
This is because the suction tank 3 is being suctioned by the suction pump 4.

5.5' is a pair of feed screw rods arranged in parallel along the paper conveyance direction on both sides of the conveyor belt 2;
, 5' are screwed with nuts 6.6'. Also,
The ends of a movable plate 7 are fixed between these nuts 6.6', and the movable plate 7 is suspended horizontally between the nuts 6.6'.

A plurality of feeding pieces 9 are fixed to the moving plate 7 at equal intervals, for peeling off the paper adsorbed on the conveyor belt 2 and feeding it into the bin 8.

The feed screw rod 5 is connected to a drive source 11 such as a reversible motor via a clutch mechanism 10. Further, the feed screw rods 5 and 5' are connected via a timing belt 13 stretched between pulleys 12 and 12' so that they rotate in the same direction and at the same speed. A solenoid 14 controls the clutch mechanism 10 on and off. The solenoid 14 is actuated by a pulse signal from a not-illustrated hinge provided near the entrance 1 for detecting the leading edge of the paper, and turns on the clutch mechanism 10 for a short time. That is, the power of the drive source 11 is transmitted to the feed screw rod 5 for a short time.

Therefore, every time paper enters 1, the feed screw rod 5
rotates at a predetermined angle and in a predetermined direction, and the nut 6 screwed onto the feed screw rod 5 moves downward. The 50 rotations of the feed screw rod are also transmitted to the feed screw rod 5' by the timing belt 13, so the nut 6' also works in conjunction with the nut 6,
Move downward. Therefore, the movable plate 7 suspended horizontally between the nuts 6.6' and the plurality of feeding pieces 9 fixed to the movable plate also move downward together with the nuts 6.6'.

Now, by appropriately selecting the amount of rotation of the feed screw rods 5, 5' each time the solenoid 14 and the clutch mechanism 10 are turned on once, and the pitch of the screws, the nut can be rotated while the clutch mechanism 10 is activated once. If 6.6' is moved downward by an amount equal to the interval between the bins 8, the sheets entering the inlet 1 can be sorted from the upper bin to the lower bin.

When the feeding piece moves downward from the position facing the lowest bin, the moving plate 7 holding the feeding piece 9 moves downward.
Step on the lower limit switch (not shown). Then, the driving source 11 is reversed by the signal output from the lower limit switch, and the movable plate 7 is moved to a position where an upper limit switch (not shown) is pressed. As a result, the feeding piece 9 comes to face the top bin.

In addition, without using all the bins 8, move the feeding piece 9 from the middle of the plurality of bins to the position facing the topmost bin again.
When returning the bin 8, that is, when sorting paper using a part of the bin 8, when a copy button (not shown) is pressed, the drive source 11 is reversed and the feeding piece 9 faces the top of the bin. It is made to come into position.

The description of the above conventional device can be found in, for example, Japanese Patent Application Laid-Open No. 53-6063.
This is explained in detail in Japanese Patent Application No. 0, and the explanation will be limited to the above-mentioned level here.

Now, in the conventional sorter, as is clear from FIGS. 1 and 3, the bins 8 are arranged parallel to each other, so that the intervals between the bins are constant. For this reason, when the Z-folded sheets 15 are sorted by the sorter, as shown in FIG. 3, the folding section 15a is bulky, so there is a drawback that the number of sheets per bin cannot be increased. .

(Objective) The present invention was made in order to eliminate the above-mentioned drawbacks, and its object is to provide a sorter that can store a large number of Z-folded sheets per bin. .

(Summary) In order to achieve the above object, the present invention generally makes the bin intervals equal when storing sheets without a folding section, and when storing Z-folded sheets, the paper entrance side of a specific bin is The feature is that the opposite end can be moved up and down using one end as an axis.

(Example) The present invention will be described in detail below with reference to the drawings.

4 and 5 are side views of one embodiment of the present invention. In the figure, the same reference numerals as in FIG. 1 represent the same or equivalent parts.

In the figure, 20a] to 20a5 indicate fixed and immovable bottles, and 20b1 to 20b have one end connected to a pivot 22.
b1 to 22 b4, and the other end is fixed to a cable or wire 23 (hereinafter referred to as cable). The bins 20a1 to 20a5 are paper stopper portions 2.
1a1 to 21a5, and the stopper portions 21a2 to 21
a5 is inserted into notch holes 24b1 to 244 formed in the bottles 20b1 to 20b4. Note that instead of this, notch holes are provided in the stopper parts 21a2 to 21a5,
The bottles 20br to 20b4 may be inserted through this.

An end of the cable 23 is connected to one end of an arm 25 pivotally supported by a pivot 26, and the other end of the arm 25 is connected to a solenoid 27. Therefore, when the solenoid 27 is activated and the arm 25 is rotated counterclockwise about the pivot 26, the bins 2 ob1 to
201) a rotates clockwise around the pivots 22b1 to 22b4 as shown in FIG. That is, the bins 20at and 201)t, 20a2 and 20b2,
−・・・・・・・.

The distance between 20a4 and 20b4 becomes larger on the cable 23 side.

Next, the operation of this embodiment will be explained. When sorting regular paper without Z-fold, as shown in Figure 4,
Without operating the solenoid 27, the bins 20b1 to 20b4
is parallel to the bins 20a1 to 20a5. As a result, the copied paper is stored in the bin 20a, similar to the conventional apparatus.

20b 1, 20a 2.20b 2, - accommodated in the rail.

On the other hand, when sorting Z-folded sheets, the user turns on a switch (not shown).

This activates the solenoid 27, and the arm 25 rotates counterclockwise as shown in FIG.

Therefore, the wire 23 moves downward and the bin 20b1
-20bt rotates clockwise around pivots 22b1-22b4, as shown in FIG. That is, each of the bins 20a1 to 20a4 and the bin 20b1
20b4 are narrower on the conveyor belt 2 side and wider on the wire 23 side.

The Z-folded paper passes through an inlet 1 of the sorter, is attracted to a conveyor belt 2, and is conveyed toward a bin.

Then, guided by the feeding piece 9, the bin 20a 1
.

20b1, 20b2, 20b3, 201)a, and is stored with the Z-folding direction first. Since the bulky portion of the paper folded into seven is stored in the large gap created by each of the bins 20az to 20a4 (7) and each of the bins 20b1 to 20b4, the number of sheets per bin of Z-folded paper is can be increased.

Note that when the Z-folded paper selection switch is turned on as described above, the solenoid 14 is activated twice each time a sheet of paper passes through the sorter entrance 1, and the feed piece 9 is moved downward. The distance traveled is twice the normal distance.

FIG. 6 shows an example of a control circuit for the solenoids 14 and 27. When normal sheets enter the sorter, the Z-fold selection switch button 31 is turned off, the switch 32 is connected to contact a, and the switch 33 is turned off. Therefore, the solenoid 27 is not activated and the bins 20bl~
20b4 is in the state shown in FIG.

When the sensor 23 provided near the sorter 1 to detect the passage of paper is turned on by the passage of the paper, a high-level signal is sent to the waveform shaping circuit 35 while the paper is passing. The rectangular wave whose waveform has been shaped by the circuit 35 is input to a first monomulti 36 which is triggered at the rising edge of the rectangular wave and outputs a signal having a pulse width of a first scheduled time. The output signal of the first monomulti 36 is input to the solenoid 14, and the solenoid 14 is activated once each time one sheet of paper enters the sorter.

Next, when the Z-fold selection switch button 31 is turned on, the switch 32 is connected and the switch 33 is turned on. This causes the solenoid 27 to operate and the bin to be in the position shown in FIG.

As in the case of normal paper, when the sensor 34 that detects the passage of paper provided near the entrance 1 of the sorter is turned on by the passage of the seven-folded paper, a high level signal is generated during the passage of the paper. is sent to the waveform shaping circuit 35. The rectangular wave whose waveform has been shaped by the circuit 35 is triggered at the rising edge of the rectangular wave, and a second circuit outputs a signal having a pulse width of a second scheduled time.
input to the monomulti 36'. The second monomulti 3
The output of 6' is input to a circuit 37 having a differentiator circuit and a double-wave rectifier circuit, thereby producing two pulses. These two pulses are sent to a solenoid 14 which is activated twice for each Z-fold sheet entering the sorter.

(Effects) According to the present invention, when Z-folded sheets enter the sorter, the gap on the side where the stopper parts 21a1 to 21a of the bin are located is increased, and the bulky Z-folded part is placed in this part. Since parts are stored, the number of sheets stored per bin can be increased.
