Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a paper storage device such as a sorter or a colleter used in a copying machine or the like to align the pages of copied paper after copying has been completed.

As shown in FIG. 1, for example, a conventional paper storage device has a plurality of bins and trays B arranged at equal intervals along a paper transport path α, and sorting is done by members (not shown) along the paper transport path α. There is known a device in which the paper C that has been conveyed is fed into a predetermined bin or tray b and stored therein.

In order to make the entire paper storage device small and compact, the distance between the upper and lower bins and the tray 6 that are in instant contact with each other is
It would be better to make it shorter, but if you do this, the distance between the vertically descending bins and trays h and h is narrow, so when you take out paper C2 from bin and tray b, your fingers will touch the bin and trays b and b.
It becomes difficult and difficult to take out the paper C from each bin and tray b because it is difficult to insert the paper C between the trays and the paper C stored in the lower bin and tray 6 gets in the way.

Purpose of the invention Paper stored in a plurality of bins and trays is
To make it extremely easy to take out sheets sequentially from a tray, and to automatically return a bin and a tray to a state in which sheets are accommodated when taking out the sheets.

It's better than that.

Each of the cams 71 to 71° is provided on a support shaft 7α, and each of the support shafts 7α is connected via a gear 1o1 and an idler wheel 1, and each cam 71 to 71G rotates synchronously by the same number of rotations. That's what I do.

7. The first gear 12 meshes with the gearwheel 10' provided on the spindle of the tenth cam 71G that is engaged with the cam, fluoro, and a5 of the tenth bin and tray 210. The third gear 14 meshes with the second gear 13 that is integrated with the
A fifth gear 16 meshes with a fourth gear 15 that is integrated with the third gear 14, and a chain sprocket 19 is connected to a rotating shaft 17 to which the fifth gear 16 is fixed via a spring clutch 18. The chain sprocket 19 is connected to a drive source 21' via a chain 20, and serves as a cam operating means.

The first and second gears 12 and 13 are rotatably supported on the rotating shaft 17, and the third and fourth gears 14 and 15 are supported on the supporting shaft 21, and are connected to the rotating shaft 17 and the supporting shaft 7'. Each gear 101.12.13.

As shown in FIG. 6, the spring clutch 18 rotates when the stopper 22 is swung by the solenoid 23 and disengaged from the protrusion 18α, and the rotation is transmitted to the rotating shaft 17, and the stopper 22 engages with the protrusion 18α. When the solenoid 23
Excitation and demagnetization are controlled by the control mechanism 24. .

The control mechanism 24 is set by a copy end signal R8 from the copying machine A, as shown in FIG.

That is, it is activated when copy sheets are sorted and stored in each bin and tray 21-2□0.

And limit switch 4J~4. It is configured to output a 1-pulse signal & to excite the solenoid 1 and 23 every time a signal is input from o, and the I-pulse signal is the same as the original copy number setting device 25. The number of sheets is inputted to an arithmetic circuit 26 having a counter function where the number of sheets is input and set.

Note that the number of copies set by the number of copies setter 25 is determined by the number of copies set by the copying machine control unit 2.
7, and copying is performed by the ON signal from the copy button 28.
AA photoreceptor 29, developing device 30, transfer device 31, charger 3
2, etc. are operated for a set number of copies according to a predetermined copying process.

Note that, if the paper storage device B itself has a counter for setting the number of copies to be sorted (the number of bins and trays to be used), the value of the counter may be input to the arithmetic circuit 26.

Next, an explanation will be given of the operation in the case where five copies are made from one original to create five copies of a document.

First, set 5 copies using the copy number setter 25 and input "5" to the compound harp control section 27 and the arithmetic circuit 26.
By turning on the copy button 2g, one document is copied five times, and the copied paper is placed in bins 1 to 5.
Sorted and stored sequentially in trays 21 to 26. Then, when all the originals are copied in the same manner and sorted and stored in the first to fifth bins and two trays to 26, and the copying operation is completed, the control mechanism 24 is activated.

When paper is taken out from the first bin and tray 21 in this state, the first limit switch 4t detects the paper removal, and the signal is input to the control mechanism 24, which outputs a one-pulse signal bird and activates the solenoid 23. Excite.

As a result, the stopper 22 swings and separates from the protrusion 18α, and the rotating shaft 27 rotates once, so that each of the cams 71 to 71
゜ rotates forward and the outer peripheral surface 9 of the first cam 7! gets on the cam follower 5 and moves the first bin and tray 21 upward FA.

For this purpose, a first bin, a tray 21 and a second bin.

The distance between the second bin and tray 22 is increased, and the second bin and tray 2.
It becomes easier to take out the paper stored in the . On the other hand, the one-pulse signal bird is sent to the arithmetic circuit 26 to reduce the input set number of sheets "5" to "4".

When you take out the paper stored in the second bin and tray 22,
The second limit switch 42 detects paper removal,
The signal is input to the control mechanism 24 and a one-pulse signal signal is output, which excites the solenoid 23.

This causes the second bin and tray 22 to swing upward in the same manner as described above, making it easier to take out the sheets stored in the third bin and tray 23. At the same time, performance n times #+2
Decrease the set number of sheets input in 6 to 13''.In the same way, each time a sheet is taken out from the 3rd to 5th bins and trays 2B to 26, it is sequentially moved upward, so each bin,
The sheets can be easily taken out from the trays 21 to 26, and the set number of sheets input to the arithmetic circuit 26 is sequentially reduced to "2", "1", and "0" in the same manner as described above.

Then, when the set number of sheets becomes "0", the arithmetic circuit 26 ((
#＋
+ + )-N Rotate only 11 times, and then rotate the 1st to 5th cams 2.
□ ~ 2G and 6th ~ 10th cams 26 ~ 21G are the initial positions, 1st ~ 5th bins, trays 2, ~ 211 and 6th ~
The 10th bin and trays 66 to 21G are swung downward to automatically return to the paper storage state.

Note that N' is the set number of sheets, and in the embodiment, ((r
o1+,)-5), that is, the rotating shaft 27 is rotated six times.

As described above, the bin or tray from which the paper was taken out can be swung upwards, and the paper stored in the next bin or tray can be taken out into the container.

In addition, the bins and trays 2□ to 210 automatically swing upward in sequence in response to the paper removal detection signal from limit switches 4□ to 4□0, so the operator only has to take out the sheets one by one. It is extremely easy to take out paper from the drawer.

Furthermore, when the paper is completely removed from the bin or tray, the bin or tray that has swung upward can automatically swing downward to return to the paper storage state.

Moreover, the first cam 7136 is not provided with the tenth cam 710.
The angle α of the 0° notch 81 is 11 degrees, and the second to ninth cams 7
The angle of the notches 82-8 of 2-711 is α2=2α1, α
8=3 α α4=4α8, to=5 α1, α6=6
When α1, α1=7α1, α6=8α1, α1=7α1 and the 10th bin and tray 2□0 are not allowed to swing upward, the arithmetic circuit 26 uses (#-N'
)< and then rotate the rotating shaft 27 by that value.

Effects of the invention Paper stored in multiple bins and trays can be transferred to the upper bin,
The sheets can be taken out one by one from the tray very easily, and the bin and tray that have been swung upward can be automatically returned to the sheet storage state after the sheets have been taken out.
