Description

[Detailed description of the invention] This invention relates to a conveyance control device used when conveying a large amount of conveyed items such as paper sheets. Automatic processing is required, and in order to meet this demand, various paper sheet processing devices have been developed and put into practical use.

Conventionally, the above-mentioned paper sheet processing equipment has the function of counting paper sheets as needed, but the concept of the counting system varies greatly depending on how important the counted value is. It changes to

For example, in devices that place importance on count values, various counting circuits are used to achieve the purpose.

However, no matter how high-performance a counting circuit is used, if an object is transported under conditions in which the counting circuit does not operate, the counting of the transported object will be ignored, and accurate counting will not be performed. cannot achieve the purpose.

Therefore, it is necessary to detect in advance whether or not counting is possible before transporting the objects.

This idea was made in view of the above points, and it detects whether or not counting is possible before transporting the object, thereby increasing the reliability of counting paper sheets, etc. that are being transported. It is an object of the present invention to provide a conveyance control device capable of accurately conveying a large amount of paper products and the like.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 schematically shows the configuration of a paper sheet conveying device, where 11 is a take-out device for taking out paper sheets 12 one by one, and 13 is a take-out device for conveying the taken-out paper sheets in the direction of the arrow. conveyor belts 14 to 143 are sorting devices for guiding conveyed paper sheets to predetermined stacking sections 15, to 154; 171-174 are paper sheet detectors for counting the number of paper sheets entering the stacking sections 151-154.

The paper sheet detectors 16□-16. For example, solar cell lamps and the like are used for 17 and 174.

However, the following paper sheet detectors 16□-16. The conveyance detection detectors 16, -16. Paper industry detector 17, ~1
74 is called the counting detector 17, to 174.

FIG. 2 shows a conveyance state detection circuit according to this invention, 161 to 16. 1 are the conveyance detection detectors shown in FIG. 1, and the signals obtained by these conveyance detection detectors 161 to 16 are input to the OR circuit 22 via amplifiers 211 to 21°, respectively.

The output terminal of this OR circuit 22 is connected to the first input terminal of an AND circuit 23.

The second input terminal of this AND circuit 23 is connected to the inverter 2.
4, a countable condition signal is supplied, and a third input terminal is supplied with a non-countable condition signal.

The above-mentioned countable condition signal uses, for example, a signal from the paper sheet removal start signal to before the generation of the paper sheet removal end signal, and the above-mentioned uncountable condition signal uses, for example, the signal from the paper sheet removal start signal to before the generation of the paper sheet removal end signal. A signal is used.

Each of these condition signals is generated, for example, by an operator operating a switch.

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

The paper sheets taken out one by one by the take-out device 11 are conveyed in the direction of arrow A by the conveyor belt 13, and then transferred to the sorting device 1.
41 to 143 and accumulated in respective accumulation sections 15□ to 154.

During this conveyance, the paper sheets are detected by the conveyance detection detectors 16, -16. Detectors 161-16. This output is input to amplifiers 21 to 215 as shown in FIG.

That is, the conveyance detection detectors 16, to 16. any one of
When a paper sheet passes through the OR circuit 22, an output as shown is generated in the OR circuit 22, which becomes an input to the AND circuit 23.

At this time, if the condition is such that counting is possible, the countable condition signal becomes 11" level, and this condition signal is transmitted to the inverter 24.
It is inverted to the '0' level and input to the AND circuit 23.

Note that at this time, the uncountable condition signal is at the 10'' level.

That is, at this time, signals such as those shown in FIG. 3 are input to the first to third input terminals of the AND circuit 23.

Therefore, the logic does not hold, and it is determined that the conveyance is normal.

At this time, if the condition is such that counting is impossible, the uncountable condition signal becomes '1' level, and this condition signal is input to the AND circuit 23.

Note that at this time, the countable condition signal is at the 10" level, so the output of the inverter 24 is at the 11" level.

That is, at this time, signals such as a=c in FIG. 4 are input to the first to third input terminals of the AND circuit 23.

Therefore, the logic is established and an output is generated from the AND circuit 23.

In other words, the fact that the logic of the AND circuit 23 has been established means that the conveyance detection detector 161 is
~16. This means that there is a paper sheet detection signal from at least one of the paper sheets, which indicates that paper sheets were conveyed in a state where counting was impossible.

Therefore, if the counting detectors 171 to 174 count when there is an output from the AND circuit 23, the counting will be inaccurate, so the operation of the device is stopped and the conveyance of paper sheets is temporarily stopped. Make it.

In this way, since paper sheets are not conveyed under conditions where counting is impossible, no counting is performed, and the reliability of counting can be improved.

In the above embodiment, the case where paper sheets are conveyed has been described, but this invention can be applied to conveyed objects other than paper sheets.

As described above, according to this invention, conditions that allow counting and conditions that cannot be counted are set, and it is possible to determine whether there is an object on the conveyance path when the condition is impossible to count, that is, the condition in which the counting circuit does not operate. Since the conveyance path is stopped when the presence of a conveyed object is detected, the conveyed object will not reach the accumulation section under conditions that make it impossible to count, thus improving the reliability of counting. It is possible to provide a conveyance control device that is highly effective, especially when it is necessary to convey a large amount of paper sheets such as mail.
