Abstract

PURPOSE: To smoothly stack bank notes by controlling the stop of the rotation of an impeller to constantly and appropriately take in bank notes when a carrying interval detection sensor to detect the carrying interval of the bank notes detects the carrying interval narrower than the set value. CONSTITUTION: When bank notes 15 are continuously carried into a temporary storage part 21 through the deposit, the carrying interval of the bank notes 15 is detected by first and second carrying interval detection sensors S1, S2, and if the detected value is larger than the preset value by an impeller control circuit, the rotation of an impeller 29 is permitted to achieve the stacking action because there is no trouble in taking the bank notes. When the detected value is smaller than the preset value, the rotational action of the impeller 29 is temporarily controlled to stop so that an impeller blade 29a causes no troubles in the carrying-in action of the next bank note 15. Even when the rotation of the temporary storage part 21 is temporarily stopped, the bank notes not subjected to the guide action of the blade are smoothly stacked under the stacking force of the next bank note.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a banknote stacking device such as that built inside an automatic teller machine, for example, and more specifically to an impeller control device that improves banknote stacking performance. The present invention relates to a banknote stacking device with functions.

(B) Prior Art In general, this type of banknote stacking device is provided as a temporary stacking section for temporarily stacking banknotes inside the main body of the device, so that banknotes can be taken in and returned from this temporary stacking section.

This time stacking unit usually has an impeller for guiding the intake installed at the front stage of the banknote loading position, and the rotating action of this impeller knocks off the rear end of the banknotes being conveyed and collects the banknotes in one place. They are guided to be accumulated one by one in a temporary accumulation section (for example, as disclosed in earlier applications, U.S. Pat. No. 59-143802 and U.S. Pat.

However, since the impeller continuously flaps and captures the banknotes conveyed to the stacking section, the position of the flap may be different, resulting in uneven alignment of the collected banknotes. , and the noise was relatively loud.

For this reason, an impeller control means can be considered in which a banknote detection sensor is provided in the front stage of the impeller and the rotation of the impeller is controlled in conjunction with each passing banknote, but in this case, detection cannot be controlled until the interval between banknotes being conveyed. When the conveyance interval is narrow, the blades that guide the stacking of the preceding banknotes collide with the leading edge of the next banknote to be conveyed, obstructing the conveyance, which causes paper jams.

(c) Problems to be Solved by the Invention The present invention provides impeller control that can always smoothly control and accumulate banknotes without causing paper jams, even when the conveyance interval of banknotes is narrow. It is intended to be a banknote stacking device with R function.

(d) Means for Solving the Problems This invention provides a banknote stacking system in which an impeller for taking in and guiding the banknotes is installed in the front stage of a banknote stacking section for stacking and stacking banknotes, and the banknotes are guided to be stacked via the impeller. The apparatus includes a conveyance interval detection sensor for detecting the conveyance interval of banknotes in the front stage of the impeller, and when a conveyance interval narrower than the set interval value is detected, impeller control controls the impeller to stop rotating. It consists of a banknote stacking device with an impeller control function.

(E) Effect of the Invention According to the present invention, when the conveyance interval detection sensor detects that the conveyance interval of banknotes continuously conveyed to the banknote stacking section is wider than the set interval value, there is no problem in taking in the banknotes. Therefore, when the impeller is allowed to rotate and the banknotes are collected and guided, and when it is detected that the conveyance interval of banknotes is narrower than the set interval value, the rotating blade becomes an obstacle to taking in the next banknote, so the banknote is Temporarily stops and controls the rotation of the impeller.

(f) Effects of the Invention In this way, by controlling the rotation and stop of the impeller in accordance with the length of the banknote conveyance interval, it is possible to always perform an appropriate banknote taking-in operation and to smoothly accumulate banknotes.

As a result, paper jams of banknotes can be reliably avoided.
Moreover, since the impeller rotates to the minimum necessary, it is effective in noise prevention, and the 4IIN structure does not become complicated, making it a highly reliable stacking device that has stable stacking performance depending on the conveyance state. becomes.

By the way, as shown in FIG.
The banknotes 15 are piled up in a horizontally long vertical position between the facing surfaces of the banknote 6 and the feeding rollers 27 and 28 facing the front surface thereof.

Bills are carried in and stacked from the upper front side of this door section 21, and are fed out from the lower front side.

In this case, an impeller 29 for guiding the intake is installed at the upper front of the door section 21, and the rotating action of the impeller 29 guides the collection of banknotes 15 carried in from diagonally above. It is set up in

Further, a first conveyance interval detection sensor S1 is provided at a front and rear position on the fourth conveyance path L4 corresponding to the front side of the impeller 29.
and a second conveyance interval detection sensor S2, the first conveyance interval detection sensor S1 is located on the front side to detect the presence or absence of bills being conveyed, and the second conveyance interval detection sensor S2 is located on the rear side. Detects the rear end of the banknote being positioned and conveyed. Based on the detection results of both sensors S1 and S2 at these front and rear positions, the conveyance interval of the banknotes can be determined.

It is known that this conveyance interval may become wider or narrower depending on the difference in feeding from the deposit port 12.
At this time, when the interval between the conveyances of the banknotes that are continuously carried into the door section 21 is sufficiently wide, the impeller 29 performs a rotation operation that does not interfere with the taking in of banknotes, but on the contrary, when the interval between the conveyance of banknotes is narrow. Since the interval is narrow, the rotary blade 29a collides with the next banknote, causing a paper jam or the like.

For this reason, a minimum conveyance interval that does not hinder the accumulation operation of the impeller 29 is set in advance, and an impeller control circuit equipped with a CPU (not shown) that stores and manages the set interval value serving as a reference is controlled. The impeller 29 is rotated by operation.
It is provided for stop control. This is so that when the conveyance interval of the banknotes 15... conveyed to the door section 21 is wider than the set interval value, there is no problem in taking in the banknotes, so the rotation of the impeller 29 is allowed to guide the accumulation. and when the conveyance interval of banknotes 15... is narrower than the set interval value,
Since the rotating blade 29a becomes a hindrance to taking in the next bill 15..., the rotational operation of the impeller 29 is controlled to be temporarily stopped via the impeller control circuit.

In this case, the impeller 29 is driven by a stepping motor (not shown), and performs a stacking operation by sequentially rotating once in response to each banknote being carried in. Further, the stop position is controlled to be in a direction that does not collide with the banknote that will be conveyed next.

Next, an explanation will be given of the accumulation operation of the -hour door section.

Now, when the banknotes 15... are successively conveyed to the -hour door section 21 due to the deposit processing, the conveyance interval of the conveyed paper 9115... is the first and second conveyance interval. The conveyance interval of the banknotes is detected via the detection sensor S1.32, and if the impeller control circuit detects that the conveyance interval is wider than the set interval value, there is no problem in taking in the banknotes 15... The impeller 29 is allowed to rotate to perform the accumulation action.

On the other hand, when it is detected that the conveyance interval of the banknotes 15 is narrower than the set interval value, the rotation operation of the impeller 29 is temporarily stopped so that the rotary blade 29a does not interfere with the conveyance operation of the next banknote. Make it.

At this time, even if the rotation of the door section 21 is temporarily stopped,
Banknotes that are not guided by the blades are smoothly stacked by the stacking force of the next banknote.

An example of this - time stop control operation will be explained with reference to the time chart of FIG. 4.

This is the second conveyance interval detection sensor S2 at position A in the figure.
Even if the rear end of the banknote 15 is detected, the first conveyance interval detection sensor S1 detects the next banknote and determines that the conveyance interval with the next banknote is narrow. Pause control. Also, at positions B and C in the figure, the second t
Since only the m-feed interval detection sensor S2 detects, it is determined that the conveyance interval between the next banknote and the next banknote is wide, and the rotation operation of the impeller 29 is permitted.

As described above, by controlling the rotation and stop of the impeller in accordance with the length of the conveyance interval of the banknotes, the banknotes can always be taken in appropriately and the banknotes can be smoothly accumulated.

As a result, paper jams of banknotes can be reliably avoided.
In addition, the impeller rotates at the minimum required level, which is effective in preventing noise, and without complicating the structure, making it a highly reliable stacking device with stable stacking performance depending on the conveyance state. Become.

In correspondence between this invention and the configuration of the above-mentioned embodiment, the banknote stacking device of this invention has the temporary door section 21 of the embodiment.
Similarly, the conveyance interval detection sensor corresponds to the first conveyance interval detection sensor S1 and the second conveyance interval detection sensor s2, and the impeller control means is connected to an impeller control circuit equipped with a CPU, etc. However, the present invention is not limited to the configuration of the embodiments described above.
