Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet counting machine that counts the number of paper sheets such as paper counters.

Some paper sheet counting machines use negative pressure (supplied from a vacuum pump, etc.) to absorb each sheet of paper one by one and count them while turning them over.

Conventionally, this type of sheet counting machine has consisted of one space-consuming vacuum pump, etc., and one relatively space-saving counting mechanism, which counts sheets based on the aforementioned negative pressure. It was provided as an integrated machine.

As a result, buttons took up space at work sites and lacked convenience.

In view of the above, an object of the present invention is to provide a paper sheet counter that is simple and free from space problems.

One embodiment of this invention will be described below.

The paper sheet counting machine according to this embodiment has a pump unit 1 and two counting units 2 and 3.
It is composed of.

The pump unit 1 includes a vacuum pump 11, a control section 12, solenoid valves 13 to 17, joint sections 18 and 19, and the like.

The valve 13 is connected to the intake side 11a and the exhaust side 1 of the vacuum pump 11.
1b, and valves 14 and 16.
valves 15 and 17 control the supply of compressed air to the counting units 2 and 3, respectively.

The counting units 2 and 3 each include a counting mechanism 21°31, vacuum switches 24 and 34, and joint parts 25 and 3.
5, control section 26, 36, etc.

Counting mechanisms 21 and 31 are controlled by suction units 22 and 32, and holders 23 and 33, respectively.

Cables 5 are led out from the counting units 2, 3, and electrically connect the counting units 2, 3 to the pump unit 1 through the cables 5&.

Also, connect the hoses 41 to 44 to the joint parts 18, 19, 2.
5° 35, the vacuum pressure button and compressed air from the vacuum pump 11 are supplied to the counting units 2 and 3.

In this way, since the counting units 2 and 3 are only connected to the pump unit 1 by the flexible hoses 41 to 44 and the cable 5, the pump unit 1 can be connected to the desk as shown in FIG. 7, while the counting units 2 and 3 can be placed on the desk 7.

Next, the operation of the paper sheet counter configured in this way will be explained.

In order to count the paper sheets 6 using, for example, the counting unit 2 in the first rotation and in FIG. 2, first, the paper sheets 6 are loaded into the holder 23 and a start switch (not shown) is operated.

In response, a start signal is sent to the control section 12 of the pump unit 1 via the control section 26, and the control section 12 starts operation of the vacuum pump 11 and also controls the valves 14 to 1.
5 to open it.

The buttons and valves 13, 16, and 17 are closed holes.

Furthermore, the control section 12 sends a counting start enable signal to the control section 26 of the counting unit 2.

In this way, vacuum pressure and compressed air are supplied to the counting unit 2 via the hoses 41 and 42, respectively, and when the vacuum pressure exceeds a predetermined value, the vacuum switch 24 is turned on.

As a result, this ON signal is sent to the number control unit 26, and the control unit 26 drives the counting mechanism 21 to count the paper sheets 6 in response to this ON signal and the above-mentioned counting start enable signal.

That is, each suction member 22 is rotated Q times as shown by the arrow in FIG. 2 to bring it into contact with the paper sheets 6 one after another, and the paper sheets 6 are sucked one by one and counted while being turned over.

The compressed air supplied through the button and hose 42 separates the sheets 6 by known means so that the above-mentioned counting operation can be carried out smoothly.

When the counting unit 2 is pressed to complete a predetermined count, the vacuum pressure becomes lower than a predetermined value and the vacuum switch 24 is turned off.

This off signal is sent to the control section 26, and the control section 26 sends a counting end signal to the control section 12 of the pump unit 1.

As a result, the control section 12 drives the valve 14.15 to close it, and the counting start enable signal is no longer sent to the control section 26.

At this time, if the counting unit 3 is not operated and the start signal is not sent to the control section 12 via the control section 36 of the unit 3, the valve 13 is opened.

As a result, the suction side 11a and the exhaust side 11 of the vacuum pump 11
b are in communication with each other, and the burden caused by inertial rotation of the vacuum pump 11 is reduced.

On the other hand, if the counting unit 3 has already been operated and a start signal has been sent to the control section 12, the control section 12 drives the valves 16 and 17 to open them and closes the valves 13 to 15. ), and at the same time sends a counting start enable signal to the control section 36 of the counting unit 3, causing it to perform counting as in the case of the counting unit 2 described above.

button, when the counting unit 2 is in the counting state, even if you press =- to start the counting unit 3, the counting start enable signal is not input to the control unit 36+, and the counting of the counting unit 2 ends at 1. Counting unit 3 is placed on standby.

During this standby period, the paper sheet 6 may be held between the holders 33 or the holder 33 may be left open.

The standby state may be displayed to the operator by, for example, driving an indicator lamp when the counting start signal is not input.

When counting by counting unit 3, the counting unit 2
is placed in a standby state.

In addition, in the above embodiment, the number of counting units was two, but
It may be three or more.

Alternatively, other control valves may be used in place of the solenoid valves 13-17.

As described above with respect to one embodiment (this invention
According to this, the pump unit and the counting unit are configured separately, and one pump unit is shared by multiple counting units, which reduces the need for expensive and space-consuming vacuum pumps, reduces costs, and Miniaturization can be achieved.

With the housing, the counting unit can be placed close at hand, for example on the desk, while the pump unit can be placed in a place where it does not interfere with work, for example on the side of the desk, and when not in use, the counting unit can also be placed on the desk. Can be stored in lower order,
It is advantageous in terms of space and is simple.
