Abstract

PURPOSE:To always keep an interval between mediums constant by providing an interval monitor unit which monitors the interval between the mediums by means of output from a passing sensor for detecting the passing of the medium and also a speed control unit so as to control the interval between the mediums. CONSTITUTION:Passing of a medium 12 is detected by a passing sensor 21 and any abnormal approaching of the medium 12 is checked by an interval monitor unit 22. In this case, for example, under a timing that a passing sensor 21-a detects the rear end of a preceding medium 12, a driving system 17 for conveying the preceding medium 12 is accelerated by a speed control unit 23. The speed of the driving system 17 becomes thereby faster than that of a conveying unit 16 and due to this difference between the speeds, the preceding medium 12 is conveyed faster than the following medium 12. When the top end of the following medium 12 is detected by the passing sensor 21-a, the conveying speed of the driving system 17 is returned back as it was and the conveying of the following medium 12 is carried out. Consequently, the interval between the mediums can be increased.

Description

[Detailed Description of the Invention] [Summary] Regarding the bill interval control method for controlling the interval between bills in a banknote dispensing machine, when an abnormal approach of a medium is detected, the speed of an independent drive system is controlled so that the interval between bills is always controlled. The purpose of the present invention is to provide a bill interval control method that maintains a constant interval between media, and to provide a media processing device in which media fed out from a delivery part in which media are stacked is transported by a transport part and processed by a processing part. , the conveyance unit is configured with a plurality of independent drive systems capable of changing conveyance speeds, a passage sensor detects passage of the medium, and an interval monitoring unit monitors the interval of the medium based on the output of the passage sensor; A speed control section is provided to control the transport speed of the drive system based on the output of the interval monitoring section, so that the interval between the media can be controlled.

[Industrial Application Field] The present invention relates to a bill spacing control method for controlling bill spacing in a banknote dispensing machine.

In the banknote dispensing machine, the medium (banknotes) fed out from the feeding unit is transported by the conveyance unit, and after the denomination is discriminated by the discrimination unit, it is distributed to the storage unit for each denomination via game 1. Minute [pull.

Therefore, depending on the discriminating performance of the discrimination section and the switching ability of Goo 1~, the interval between the fed out media needs to be a certain distance. Therefore, it is important to keep the distance between the media constant.
You need to control it.

``Prior Art'' As a conventional banknote dispensing machine, there is one as shown in FIG. 3, for example.

In FIG. 3, ] is a feeding unit 1 that feeds out the medium (banknotes) 2, 3 is a conveying unit consisting of an eyelid 4, a belt 5, and a drive unit 6, and 7 is a denomination of the medium 2. Identification part to cover, 8 is medium 2
9 and 10 are the storage parts.

In such a banknote dispensing machine, for example, a bundle of banknotes as a medium is input into an input slot (not shown). This banknote is inserted [1
It is stacked on a feeding section 1 provided nearby. These banknotes are sequentially fed out one by one from the feeding section 1 by a feeding roller (not shown).

[Problem to be Solved by the Invention 1 Here, since the medium 2 needs to be spaced at a certain distance due to the discrimination performance of the source separating section 7 and the switching ability of the gate 8, the medium 2 must be separated from the feeding section. 1 is rolled out one by one at a predetermined interval 07'c''.
Note that the interval 1 of the medium 2 depended on the feeding of the feeding section 1.

However, the force exerted between the feeding I] 1 and the medium differs depending on the medium, and also the contact point between the 1] 1 and the 1 and the medium is different, and the previously fed , the next medium may be fed out with almost no interval,
It was not possible to always maintain the spacing above a certain level.

When conveying the medium [Due to the speed difference or frictional force difference between the lower belts, there was almost no gap between the previous medium and the next medium.

Therefore,. Since it was not possible to reliably capture the image taken by the gate, I decided to restrict it as a medium of abnormal approach. As a result, the media acceptance rate decreases,
There was a problem in that the processing capacity decreased.

The present invention has been made in view of such conventional problems, and once the sudden approach of the medium is detected, the speed of the independent drive system is controlled 1 to constantly maintain the distance between the media. The aim is to provide a formula for controlling the bill spacing that is maintained constant.

[Means to solve the problem] FIG. 1 is a diagram illustrating the principle of the present invention.

In FIG. 1, J3 includes a feeding section 11 for feeding out stacked media, a conveying section 16 for conveying the medium, a processing section 1 for processing the medium, and a numeral 17 for the conveying section 16. A plurality of independent drive systems that can change the conveyance speed; 21 is a passage sensor that detects passage of the medium; 22 is a passage sensor 21;
An interval monitoring section 23 monitors the interval between the media based on the output of the interval monitoring section 22, and a speed control section 23 controls the transport speed of the drive system 17 based on the output of the interval monitoring section 22.

[Function] According to the present invention (13), when the medium (banknote) is fed out from the feeding section, the passing of the medium is detected by the passing sensor 1,
11: Checks abnormal approach of the medium in the interval monitoring unit. Then, by controlling the speeds of a plurality of drive systems set to Xγ by a speed control section, the interval between the media is widened.

Therefore, since the C1 medium is stored in the storage section without being lost, it is possible to improve the medium reception rate and increase the processing capacity.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 2 is a diagram showing an embodiment of the present invention.

In FIG. 2, 11 is a feeding unit that feeds media and banknotes 12 one by one; 3 is a discrimination unit that discriminates the denomination of the medium 12; 14 is a gate for sorting the discriminated media 12 into denominations; Reference numerals 15A and 15B are storage units that store media 12 sorted by denomination.

Reference numeral 16 denotes a conveying section that conveys the medium 12 fed out from the feeding section 11, and the conveying section 16 includes a plurality of independent drive systems 17.
It is a collection of. An independent drive system 17 drives the roller 1
8, a belt 19, and a small drive motor 20 provided on the roller 18.

Reference numeral 21 denotes each passage sensor disposed at the front, middle, and rear of the drive system 17, and each passage sensor 21 detects passage of the medium 11. The output of each passing sensor 21 is input to the interval monitoring section 22, and the interval monitoring section 22 is connected to the storage section 15A,
15B, it is checked for abnormal approach of the medium 12 such that the medium 12 cannot be photographed correctly for each denomination.

23 is a speed control section, and the speed control section 23 controls the speed of the drive motor 20 based on the monitoring result of the interval monitoring section 22.

Next, the operation will be explained.

The medium 12 is fed out one by one from the feeding section 11 and conveyed by the conveyance section 16. At this time, the medium 12 that was fed out
Suppose that the feeding occurs with almost no gap due to the friction of the feeding roller or the belt. Then, the passage sensor 21 detects the passage of the medium 12, and the interval monitoring section 22 checks whether the medium 12 is approaching abnormally.

In this case, for example, at the timing when the passage sensor 21-a detects the rear end of the preceding medium, the speed control unit 23 increases the speed of the drive system 17 that conveys the preceding medium. Therefore,
The speed of the drive system 17 is faster than that of the transport section 16, and due to this speed difference, the leading medium is transported faster than the trailing medium. When the passing sensor 21-a detects the leading edge of the trailing medium, the conveyance speed of the drive system 17 is returned to the original speed, and the trailing medium is conveyed. This allows the media 12 to be spaced apart.

Therefore, the fed-out medium 12 is not rejected, passes through the discrimination section 13, and is sent to the storage section 1 by the gate 14.
5A. It is stored in 15B. As a result, the reception rate of the medium 12 can be improved, and the processing capacity can be increased.

[Effects of the Invention] As explained above, since abnormal approach of the medium is checked and the speed of the independent drive system is controlled,
Media spacing can be increased. As a result, since no media is rejected, the media acceptance rate can be improved and the processing capacity can be increased.
