Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for taking out a desired number of paper sheets in a paper sheet counting machine.

Conventionally, paper sheet counters have been known in which a suction device attached to a rotary tube rotates and revolves around a large number of paper sheets held in a paper sheet loading section to suction and count the sheets one by one. .

However, with this type of paper sheet counting machine, the operator has to count the number of times the desired number of sheets have been taken out, which is very tedious work. Each time the counting operation was stopped, the worker had to operate the reset button to stop the counting operation, which was very troublesome.

Furthermore, in conventional paper sheet counting machines, once counting starts, the counting operation continues until the paper leaves are exhausted from the paper loading section, so the last sheet counted does not make up the desired number of sheets. , there were some inconveniences such as a bundle of paper sheets with a fractional number of sheets.

The present invention has been made in view of the above circumstances, and its purpose is to eliminate the need for workers to count the number of times,
It is possible to automatically count the number of times of counting and stop the counting operation automatically when the desired number of counts is reached, and when there are no more sheets to be counted in the sheet loading section, replenish the sheet with more sheets and continue counting. To provide a device for taking out a desired number of paper sheets in a paper sheet counting machine, which allows a desired number of paper sheets to be sampled at an initially set desired number of times.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The paper sheet loading section A is composed of an L-shaped paper tray 1, a holder 2, and a paper press plate 3.

A groove 4 is provided in the paper tray 1 so that the holder 2 and the paper press plate 3 can be moved.

Further, the holder 2 and the paper pressing plate 3 are pressed against each other by a spring (not shown) in a direction so as to sandwich the group of paper sheets 5.

Further, the sheet group 5 held by a second spring (not shown) is urged in the direction of being pressed by the suction member 6.

A rotating barrel 7 is disposed near the sheet loading section A, and a suction unit 6 is attached to the rotating barrel 7. The rotation of the rotating barrel 7 causes the suction unit 6 to revolve while rotating. The number of paper sheets is counted using the same method.

Further, an electromagnetic solenoid 8 is disposed near the sheet loading section A, and this electromagnetic solenoid 8 operates when the counted number of sheets reaches a preset desired number.
Counted sheets and uncounted sheets are separated.

The paper press plate 3 is fixed to a shaft 11, and the shaft 11 is attached to a guide block (not shown) so that the paper press plate 3 and the groove portion 4 are always perpendicular to each other.

Further, the shaft 11 and the link 12 are rotatably attached to each other.

The other end of this link 12 has a long hole 13, and a pin 1 is fixed to a cam 15 which is rotated by a motor 14.
6 has been inserted.

The cam 15 also controls the opening/closing state of the paper press plate 3.
When the detection microswitch 17 is attached and the separator 9 performs separation and sorting, the motor 14 starts rotating counterclockwise in the figure, and when the paper presser plate 3 is at its most open position, the microswitch 17 is turned on, and the motor 14 is turned on. 14 is configured to be stopped.

Further, when it is confirmed that the desired number of sorted sheets have been taken out, the motor 14 starts rotating in the same direction as described above, and stops at the position where the microswitch 17 is turned off.

In addition, the long hole 13 is connected to the pin 16 in the state immediately before starting counting in the diagram.
is located at the center of the elongated hole 13 in order to absorb vibrations caused by contact, suction, and separation operations between the sheet group 5 and the suction bow head 6 during counting.

Next, an embodiment of the circuit according to the present invention will be described.

FIG. 2 is a block circuit diagram.

The number setting device 20 is a device for inputting the desired number of sheets to be taken out, and the number setting device 21 is a device for inputting the desired number of times to take out.

The control circuit 50 will be explained below.

That is, the sheet number counting circuit 22 is a circuit for counting the pulses generated by a counting device (not shown) emitting pulses each time a sheet is turned over while the suction device 6 shown in FIG.

The number counting circuit 23 is a circuit that counts the number of times using a signal emitted when the paper pressing plate 3 moves in a direction where the counted paper sheets can be easily taken out at the time when counting of the desired number of sheets is completed.

The number of sheets matching detection circuit 24 and the number of sheets matching detection circuit 25 are circuits that detect whether the setting and the count match, respectively.
An H signal is output only when there is a match.

In particular, when the number of times setting is O, the number of times matching detection circuit 25 is configured to always output an L signal.

Next, the signal from the start button 26 is input to the set terminal S of the SR type flip-flop (hereinafter referred to as FF) via the INV 27, and the signal from the stop button 28 is input to the set terminal S of the SR type flip-flop (hereinafter referred to as FF).
The signal is input to the OR gate 30 via the NV29, and the output of the OR gate 30 is further input to the reset terminal R of the FF.

A number match signal (H signal) and a detection signal (H pulse signal) from an extraction completion detection circuit 31 (described later) are inputted to the other input terminal of the OR gate 30 via an AND gate 32.

The output of the number of sheets matching detection circuit 24 is input to a paper presser plate and separator control circuit 33, which will be described later.
4 to the AND gate 35.

The other input terminal of the AND gate 35 is terminal 1 of the FF.
The output signal from is input.

The paper presser plate and separator control circuit 33 operates the separator 9 when the number of sheets counts matches, and at the same time rotates the motor 14 until the micro switch 17 is turned on to make it easier to pull out the sheets, and the motor 14 is rotated until the microswitch 17 is turned on and is in the counting position. , is a circuit that detects whether it is at the take-out position.

Further, the paper presser plate and separator control circuit 33 resets the sheet number counting circuit 22 and the sheet number matching detection circuit 24.
When a discrepancy signal (L signal) is input from
After returning to normal state, the separator 9 is released to prevent the sheet group 5 from falling apart.

Then, as shown by the output signal of the AND gate 35 and the dotted lines in FIG. 2, each position of the paper presser plate 3, separator 9, and drive mechanism 36 (that is, the suction unit 6 attached to the rotary tube 7) can start counting. Two output signals from the fixed position detection circuit 37 that detect whether the position is set are AN
The signal is input to the D gate 38.

The output of the AND gate 38 is input to the drive mechanism 36, so that the suction unit 6 starts the suction operation and the counting operation is started.

Further, the fixed position detection circuit 37 is configured to always output an H signal when counting, and perform a detection operation when not counting.

Further, the H signal from terminal 0 of the FF is inputted as a reset signal to the number and number counting circuits 23 and 22.

Next, the take-out completion detection circuit 31 is a circuit that confirms and detects that the counted and sorted paper sheets are taken out manually or by a take-out device (not shown), and that the counted paper sheets have been taken out. , At the time of detection, a completion signal of an H pulse signal is output.

The completion signal is input to the AND gate 39 and the AND gate 32, and one of the AND gates is opened according to the output of the number coincidence detection circuit 25, and if there is a disagreement, the number counting circuit 22 is input, and if there is a coincidence, the OR gate 30 is input. The FFs are configured to be reset via the respective FFs.

Next, the operation of the embodiment configured as described above will be explained.

Load a large number of sheets into the sheet loading section A in advance, and then input the desired number of sheets into the sheet number setting device 20, for example 25 if you want a bundle of 25 sheets, and also input the number of sheets into the sheet number setting device 21. For example, if you wish to obtain 30 sets of paper sheets, enter 30.

Then, when the start button 26 is pressed, the H signal is input to the set terminal S of the FF via the INV 27.

Since the sheet number counting circuit 22 has been reset by this, the sheet number coincidence detection circuit 24 issues an L signal and opens the gate of the AND gate 35 via the INV34.

Also, by setting the FF, the AND gate 35
The output becomes an H signal and is input to the AND gate 38.

Since the rotary cylinder 7 position of the drive mechanism 36 is configured to be set at the home position when not counting, the home position detection circuit 3
7 outputs an H signal, so the AND gate
The output of the gate 38 becomes an H signal and is given to the drive mechanism 36.
A vacuum pump (not shown) is activated to rotate the rotary cylinder 7 and start a counting operation.

As mentioned above, when the counting operation is started, a counting pulse is emitted every time one sheet is counted and is input to the sheet number counting circuit 22.
Furthermore, the output is constantly compared with the signal from the sheet number setting device 20 in the sheet number coincidence detection circuit 24.

When 25 sheets of paper are counted and match the set number,
An H signal is output from the number of sheets coincidence detection circuit 24, which drives the separator 9 and the paper presser plate 3, and the output signal becomes an L signal by the INV 34, which is connected to the AND gate 35 and the AN.
The D gate 38 is closed and each device of the drive mechanism 36 is stopped.

Further, when the paper presser plate and separator control circuit 33 is activated, a counting pulse is outputted from the circuit, and is inputted to the number of times counting circuit 23 and counted as one.

However, since this counting number does not match the set number,
The L signal is output from the number match detection circuit 25, and the I
Only the AND gate 39 is opened via the NV40, and when the paper sheets are taken out by hand or a device for automatically taking out paper sheets is installed, the removal completion detection circuit 31 detects this. , Zarani H
A signal pulse is output and input to AND gate 39, A, and ND gate 32.

At this point, the number counting circuit 22 is reset via the AND gate 39. Furthermore, the number matching detection circuit 24 outputs an L signal due to the mismatch, and after the paper presser plate 3 returns to its normal position due to the matching signal, Separator 9 returns.

Furthermore, the matching signal is converted into an H signal via INV 34 and AND gate 35 and input to AND gate 38.
The start of operation of the drive mechanism 36 is delayed until the home position is confirmed by the home position detection circuit 37.

In the same manner, counting is performed one after another and when the 30th sheet count is taken, the output from the number coincidence detection circuit 25 becomes an H signal, which opens the gate of the AND gate 32, and the H signal from the removal completion detection circuit 31 is output. The signal pulse is AND gate 3
2, the start holding FF is reset via the OR gate 30, and the AND gate 35 is closed to stop the subsequent counting operation.
The counting circuits 22 and 23 for counting the number of sheets and the number of times are reset by the output from the terminal 0 of F, and the counting operation is completed with the paper presser plate 3 and separator 9 returned to their normal positions.

Further, the output of the stop button 28 is inputted to the reset terminal H of the FF via the INV 29 and the OR gate 30, thereby making it possible to stop counting midway.

Further, it is also easy to execute sheet counting when the stop button 28 is pressed and stop the sheet counting when the sheet counting is completed.

Next, another embodiment will be described based on FIG.

This embodiment is the same as the previous embodiment except that a temporary stop circuit 51 is provided, and when the temporary stop switch 41 is turned on, the INV 42 and the
It is configured to close the gate of the AND gate 35 via the NV43 to stop the drive, and further reset only the sheet number counting circuit 22 via the OR gate 44 to hold the data content of the number counting circuit 23. .

In the embodiment configured as described above, when taking out paper sheets tens or hundreds of times in units of 100 sheets, for example, the stop switch 41 is temporarily turned ON when the number of sheets is running low. By stopping and replenishing paper sheets, and then returning the switch 41 to its original position, counting is started again, and it is possible to obtain the desired number of paper sheet bundles set at the beginning.

In addition, if a mid-way stop occurs due to poor paper loading conditions, etc., by inputting a mid-stop occurrence signal on the same line as the temporary stop, it is possible to reload the paper without erasing the number of times data. can.

Furthermore, by having a device that automatically takes out sheets after counting, and a device such as a strapping machine that automatically processes the sheets that are taken out, other tasks can be carried out until all loaded sheets are counted. There are benefits such as having more time and improving work efficiency.

It is also possible to easily implement a device that displays the number of times or a device that notifies you that a given number of times has been completed.

As described above, according to the present invention, when taking out a desired number of sheets, by setting the number of times of taking out at the beginning, it can be automatically stopped at the desired number of times, which simplifies the operation and is very convenient.

Further, by providing a temporary stop circuit, there is an effect that the number of times data is not lost during replenishment.
