Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic paper sheet handling device, and relates to a device suitable for making it difficult for trouble to occur during post-processing after separation of paper sheets.

[Conventional technology]

Conventional devices detect the conveyance status of a single sheet using a sensor, and optimally control the phase of the impeller based on this information. With such a structure, it is not possible to change the cycle of the sheets being conveyed, so there may be cases where sheets that have been conveyed abnormally close to each other must be taken into the impeller.

When paper sheets are transported close to this abnormality, the rotational phase control of the impeller cannot respond in time, and this abnormality occurs between the same blades as the paper sheets that were previously taken between the blades. You will have no choice but to take in the paper leaf that approaches you. Examples of this type of device include:

Unexamined Japanese Patent Publication No. 60-258054 is mentioned.

[Problem that the invention seeks to solve]

In the conventional technology, the paper sheets that were later taken in between the blades were not sufficiently taken in between the blades, resulting in poor alignment during stacking, or the sheets that were taken in from the blades were not properly taken in between the blades. There is a problem that the particles fly out without being taken in, and these points have not been sufficiently considered.

In other words, in the conventional technology, no consideration is given to the cycle of paper sheets that are transported and processed, and when the paper sheets are transported at an abnormally short cycle, the paper sheet stacking section, which is a post-processing section, There was a problem that paper sheets were not accumulated in the desired state.

An object of the present invention is to eliminate obstacles in a paper sheet stacking section that is a post-processing section for paper sheets that are transported and processed.

[Means for solving problems]

The above purpose is to allow the stacking means to pick up the paper sheets when the paper sheets, which have been separated one time by the separating means that determines the timing of conveyance of the paper sheets and delivered to the next conveyance path, reach the stacking means.
This is achieved by controlling the timing of transferring the paper sheets from the separating means to the conveying means so that the paper sheets are in an operating state suitable for loading.

[Effect]

The separating means determines the timing for transferring the paper sheets from the separating means to the conveying means, and transfers the paper sheets so that when one sheet reaches the accumulating means, the timing is optimal for the accumulating means to receive the paper sheets. Separate the leaves.

As a result, paper sheets are always received in a stable state by the stacking means.

Figure 2 shows the above-mentioned primary stacker 6, 1,000 yen recycling box 10. This is a schematic diagram of the separating section 3 and accumulating section 7 in the 10,000 yen recycling box 111 and safe 12, and FIGS. 3 and 4 show the separating section 3 and accumulating section 7 in FIG. 2 individually extracted. This is an easy-to-understand overview.

Next, the configuration of the accumulation section 7 will be explained. 13a is a transport bell) 1
Although not shown, the roller for driving the roller 3b is rotationally driven in the direction indicated by the arrow by another driving means (not shown). The conveyor belt (13b) is for pinching and conveying banknotes A, and the belts are arranged to face each other. Reference numeral 22 is a direction switching guide for changing the direction of conveyance of the conveyed banknotes, and is swung in the direction of an arrow indicated by a broken line by another driving means (not shown). 24 is a guide for guiding the banknotes to the impeller 7a. The impeller 7a is for accumulating the banknotes that have been conveyed one by one, and has blades arranged at equal intervals on one circumference.Although not shown, the impeller 7a uses the power transmitted from the conveyance roller drive means to drive the drive gear. 7d, an intermediate gear 7c, and a driven gear 7b. Reference numeral 14 denotes a feed roller for feeding banknotes between the blades of the impeller 7a.The rollers are arranged in a pair facing each other, 14a is a rubber roller, and 14b is a metal roller, which are pressed against each other.

Although not shown, the rubber roller 14a is rotated by another drive source. 15 is a frame. 16 is a container for storing the transported and collected banknotes. 17 is a push plate for supporting the stacked banknotes. This push plate 17 is guided by a guide arm 18 in order to move the stacked banknotes A in the vertical direction. 26 is a ball screw for driving the push plate 17, and is engaged with the push plate 17. Although not shown, the shaft of the ball screw 26 is rotationally driven by another drive source.

Furthermore, the position of the sensor 23 is such that the rotational phase of the impeller 7a when the output of the sensor 23 is generated is the optimum rotational phase for pushing the bill pushed by the pushing row 214 between the blades of the impeller 7a. It is in a position where

Next, the configuration of the 1-separation section 3 will be explained.

Reference numeral 3a denotes a feed-out roller for feeding forward the topmost banknote A of the stacked banknotes, one surface of which is made of a rubber material and rotates intermittently while being pressed against the stacked banknotes. The driving source for this intermittent rotation is a feed roller 3C, which will be described later. That is, the rotational force of the shaft of the feed roller 3C is transmitted by the belt 21, thereby rotating the notched cam 20, and the rubber roller 19 in pressure contact with the notched cam 20 is intermittently rotated.

As a result, the feed roller 3a, which rotates integrally with the rubber roller 19, is driven intermittently.

3C is a feed row 2 for separating the banknotes A fed out by the feeding roller 3a one by one and feeding them to the next conveying means.1 Although not shown in the figure, a pulse motor is used to rotate the banknotes A for the required number of rotations. Only drive.

Reference numeral 3b denotes a gate roller for separating two or more banknotes into one sheet at a time, and is made of a rubber roller that has a high coefficient of friction with the banknotes and is fixed thereto.

27 is a first sensor for detecting the passage timing of a banknote, 27a is a light emitting sensor, and 27b is a light receiving sensor. These sensors 27a and 27b are arranged immediately after the feed roller 3C on both sides of the surface through which the banknote A passes, and
It is placed so that it outputs an output when it passes.

Reference numeral 13b' denotes a belt for holding and conveying banknotes A, and a pair of belts are arranged to face each other.

Reference numeral 138' denotes a guide roller for causing the bell 13b' to travel. Further, although not shown in the figure, the Pel 13b' is driven to run by another drive roller.

Next, FIGS. 5 and 6 show the control system for the motors that drive the feed roller 3c and the feed roller 3a.
This will be explained using FIGS. 7 and 8.

As shown in FIG. 5, the motor control circuit includes an interface for receiving the outputs of the sensor 23 and the sensor 27, and a calculation section for performing calculations.

It consists of a control table for obtaining a target value to be given to the motor to be controlled based on the calculation results, a control section for controlling the motor based on the target value, and an interface for transmitting control signals to the motor. .

An example of what is performed by the control circuit will be explained with reference to FIGS. 6 and 7. As shown in Figure 21g6, the output detection times TB and Tn of the sensor 27 and the sensor 23, and the predetermined time l1lo during which the banknote is conveyed from the sensor 27 to the impeller 7a.
Based on the integer part n of Q and the rotation period Δt between the blades when the rotation period Δt between the blades of the impeller exists Q times between the output time of the sensor 23 and the output time of the sensor 27. , the arithmetic unit performs a predetermined arithmetic operation. Based on this calculation result, a time t1 corresponding to the calculation result is selected from the control table shown in FIG. Next, as shown in FIG. 8, the motor is controlled based on this time tl and a preset motor rotation control pattern.

That is, the normal rotation speed of the motor is N. Then, when controlling the motor, the motor rotation speed is linearly set to 0.
The speed is reduced to 1 NO, and then the speed is 1 determined from the control table.
It is operated at a rotational speed of 0.1 N o for 1 hour, and then the speed is linearly increased again by 0.1Δ to a predetermined rotational speed No.

Another control method performed by the control circuit is to determine the motor control content by calculating the time t1t'' using the following equation without using the control table shown in FIG.

In addition, although not shown in the figure, the calculation unit calculates the time (Δt-('l'H-n-Δt-TITo)) for temporarily stopping the motor, and the motor is driven at a predetermined rotation speed except for this time. There is a way.

The above configuration enables first-order operation.

In the separating section, the stacked banknotes are pressed against the feed-out roller by a push plate, and in this state, the feed-out roller rotates intermittently to feed the banknotes between the feed row 2 and the gate roller, where the feed roller rotates and the banknotes are It is possible to separate the sheets one by one and deliver them to the next conveyance path. In this case, the conveyance cycle of the banknotes can be controlled by the sensor provided immediately after leaving the separating section before the banknotes are sent out to the next conveyance path. On the other hand, in the banknote stacking section, after the banknotes being conveyed one by one are fed between the blades of the impeller using a feed roller, the banknotes are held and conveyed by the impeller until one banknote comes into contact with a stopper. After coming into contact with the stopper, the banknotes can be removed from the impeller again and stacked. Also.

When the banknotes are fed into the impeller, the banknote period can be controlled in advance by the separation unit so that the banknotes are placed in the optimal phase between the blades.

The above operations produce the following effects.

The banknotes separated by the separator are always taken into the impeller of the next stacking section in the optimum phase, so that two banknotes can be stably stacked. In addition, in this case, the separation pulse motor provided to separate a predetermined number of banknotes can be used to control the transport cycle of banknotes during separation, so it appears that the phase control of the impeller is not being performed. A motor for single-impeller phase control can be omitted, resulting in cost reduction.

〔Effect of the invention〕

According to the present invention, since it is possible to intermittently transport paper sheets in synchronization with the optimum processing timing of paper sheets in the post-processing section for stacking paper sheets, This has the effect of reducing obstacles in handling.

Furthermore, since there is no need to provide a dedicated control motor or the like as a drive source for the post-processing section, there is also the effect of reducing costs.
