Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a paper sheet for feeding paper sheets such as banknotes into a paper sheet stacking stacker, and stacking them in an organized state in the paper sheet stacking stacker. The present invention relates to an integrated device.

[Prior Art] A paper sheet stacking device is used, for example, to stack paper sheets after discrimination / counting in a bill counting processing device. Those that are stacked and stored are generally used. For this purpose, a paper stacking stacker for storing the paper is provided, and the paper is discriminated for authenticity, denomination, presence / absence of damage, front / back discrimination, etc. at the discrimination section, and the number of sheets is counted before being conveyed. The paper is conveyed along a conveyor and is sequentially fed to the stacker for stacking paper sheets. An impeller-type paper sheet guide means is used to guide the paper sheets supplied from the transport conveyor into the paper sheet stacking stacker in a uniform posture.

The paper sheet guide means has an impeller formed by arranging a plurality of paper sheet holding blades on a roller at a predetermined pitch interval. The impeller is attached to a rotary shaft, and the rotary shaft is attached. Is configured to be rotated by a rotation driving means such as a motor, and the paper sheet guiding means is arranged between the exit portion of the conveyor and the paper sheet carrying-in portion of the paper sheet stacking stacker.

Therefore, while the impeller is being rotated, if a paper sheet is fed from the exit of the conveyor to the impeller, it will be caught between the adjacent blades of this impeller,
As a result, the paper sheet is taken out of the conveyor.
Then, when the impeller rotates and the paper sheet becomes horizontal at a position on the paper sheet stacking stacker, the paper sheet may abut a guide wall extending above the paper sheet stacking stacker. As a result, it is separated from the impeller and falls into the stacker of paper sheets under its own weight.

Here, the transport conveyor is configured to be transported with the short side direction of the paper sheet facing forward and backward, and therefore, to sandwich the position near both ends in the longitudinal direction of the paper sheet that is transported along the transport conveyor. At least a pair of impellers are attached to the rotary shaft.

[Problems to be Solved by the Invention] By the way, since the paper sheet is fed from the conveyor to the adjacent blades of the impeller while the impeller rotates, the leading edge of the paper sheet is the front and rear blades. Depending on the position between the blades, it may not be possible to enter the position between the blades. That is, when the front blade of the pair of blades located before and after the impeller in the rotation direction is near the entrance path of the paper sheet, when the paper sheet enters, the paper sheet is held by the blade. You can enter up to the position you want.

However, when the paper sheet enters when the rear blade is located near the approach path of the paper sheet, the blade rotates before the paper sheet completely enters the holding position,
The sheet may be taken out without being pinched. In this way, if the paper sheet is not clamped by the impeller, when it falls into the paper sheet stacking stacker, the posture will be disturbed and misalignment will occur. There is the inconvenience of falling out of the leaf stacker.

In order to prevent such an inconvenience, it is conceivable to increase the number of blades planted in the impeller to reduce the interval between adjacent blades, but in this way, the blades are planted. There is a problem in that the diameter of the roller must be increased and the device becomes large.

The present invention has been made in view of the above points, and an object of the present invention is to make it possible to reliably hold a paper sheet without increasing the number of blades to be planted in the impeller. An object of the present invention is to provide a paper sheet stacking device provided with a type of paper sheet guiding means.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention relates to a blade of at least one impeller of a plurality of impellers mounted on a rotating shaft and a blade of another impeller. It is characterized in that it is arranged at a position where the phase is shifted by a predetermined amount.

[Operation] With the above-described configuration, when a blade that is located rearward in the rotation direction among the adjacent blades of one impeller approaches the paper entry path, a paper sheet enters: The front blade of the adjacent blades of the other impeller in which the blade is planted at a position shifted from the impeller is located at a position near the paper sheet entry path. Therefore, even if the above-mentioned one impeller cannot hold the paper sheet,
Since the other impeller can hold the sheet, the sheet can be fed into the sheet stacking stacker in a stable state without disturbing the posture of the sheet.

[Embodiment] An embodiment of the present invention will be described below in detail with reference to the drawings.

First, FIG. 1 shows the overall configuration of the paper sheet stacking apparatus. In the figure, reference numeral 1 denotes a paper sheet stacking stacker, and the paper sheet stacking stacker 1 defines a paper sheet storage unit 2 by front and rear, and left and right peripheral walls 1a. Further, the paper sheet stacking stacker 1 is provided with openable / closable bottom walls 3a, 3b, and the paper sheet B is provided with the bottom walls 3a, 3b.
Stacked on 3b and accumulated. And
When a predetermined number of sheets B are stacked, the bottom walls 3a and 3b are opened and the stacked sheets are stored in a safe or the like provided below the stacking stacker 1.

In order to convey the paper sheet B toward the paper sheet stacking stacker 1,
A transfer conveyor 10 is provided. The transport conveyor 10 is configured to transport the paper sheet B with its short side facing forward and backward. The transport conveyor 10 branches to left and right at an intermediate position of the transport path, and transport paths 10a, 10b.
It has become possible to move to. Therefore, on the upstream side of the transport path, the discrimination and counting of the transported paper sheets are performed, and the front / back determination is also performed, and based on the result of the front / back determination, the sorting member 11 provided at the branch portion of the transport conveyor 10 The paper sheet is distributed to either the one side conveyance path 10a or the other side conveyance path 10b and is fed to the paper sheet stacking stacker 1. As a result, the paper sheet B is stored in the paper sheet storage unit 2 of the paper sheet stacking stacker 1.
Will be gathered in a state where the front and back are aligned.

Between the exit portion of the paper sheet B and the entrance portion of the paper sheet stacking stacker 1 on the transport paths 10a and 10b, impeller-type paper sheet guiding means 20 is provided. This paper sheet guide means 20
As is clear from FIG. 2, the rotary shaft 21 is driven to rotate by a rotary driving means (not shown) such as a motor.
A pair of rollers 22 are fixedly provided on the rotary shaft 21, and each of the rollers 22 has a plurality of blades 23 for holding the sheet B at a predetermined pitch in the circumferential direction. It has been planted. Each of these blades 23 is composed of a plate piece having elasticity, and a bent portion 24 is formed at an intermediate position in the length direction thereof.
The paper sheet B is caught between the inner surface of the front end of the sheet and the sheet. Therefore, the roller 22 and the blade 23 cause the impeller 25 to move.
Is configured.

Furthermore, at the upper position of the peripheral wall 1a of the paper stacking stacker 1,
The guide wall 26 is provided, and when the paper sheet B held between the adjacent blades 23, 23 of the impeller 25 is in a horizontal state, the guide wall 26 is brought into contact with the impeller 25 to impinge the impeller 25. It is designed to be released from the holding state by 25 and fall into the paper stacking stacker 1 by its own weight.

Here, the pair of impellers 25 mounted on the rotary shaft 21 have the same shape of the roller 22 and the same number and pitch intervals of the blades 23 planted on the roller 22, but the blades 23 are planted on each other. As shown in FIG. 3, the positions are displaced from each other by about a half pitch in the rotational direction. As a result,
When one of the pair of impellers is 25a and the other is 25b, the blades 23a planted in one roller 22a of the rollers 22a, 22b are shown by solid lines in the figure. As shown by the dotted line, the blades 23b planted on the other roller 22b are arranged so that the blades 23a and 23b are alternately positioned at equal intervals in the rotation direction.

The present embodiment is configured as described above, and its operation will be described next.

The sheet B conveyed along the conveyer conveyor 10 is moved to the conveying path 10a or the conveying path 10b by the sorting member 11 according to the front and back sides thereof, and either the left side or the right side provided above the sheet stacking stacker 1 is provided. It is sent to the sheet guide means 20.

Here, the paper sheet proposal means 2 while the paper sheet B is being conveyed via the conveyance path 10a or the conveyance path 10b in the conveyance conveyor 10.
By rotating the rotary shaft 21 of 0, when the paper sheet B is sent out from the conveyor 10, the paper sheet B enters the adjacent blades 23, 23 forming the impeller 25 and is sandwiched therebetween. Then, when the impeller 25 rotates by a predetermined angle, the paper sheet B held by the impeller 25 becomes horizontal in its posture. At this time, the paper sheet B comes into contact with the guide wall 26, comes out of the impeller 25, falls into the paper sheet stacking stacker 1 by its own weight, and is stacked in the paper sheet storage unit 2 in the paper sheet stacking stacker 1. It Here, in order to surely hold the paper sheet B by the impeller 25, the rotation speed of the impeller 25 is set to be somewhat slower than the transport speed of the paper sheet B by the transport conveyor 10.

Thus, a pair of impellers 25a, 25 mounted on the same rotary shaft 21.
Since the blades 23a and 23b forming b are not provided at the same position but are arranged so as to be out of phase with each other by a half pitch, as shown in FIG. Route 10
When the paper sheet guiding means 20 is fed from the exit position E of a or 10b and is within the range of the angle θ, the impeller 25
It is received between the blades 23a, 23a of a. However, when the position near the front blade, that is, the range of the first half angle θ1 in the rotation direction of the paper receiving angle θ is at the exit position E of the paper B, the tip of the front blade 23a and the rear of the blade 23a of the impeller 25a. The paper sheet B can be reliably held between the blade 23a and the bent portion 24a.

However, a position near the rear blade of the impeller 25a,
That is, when the range of the latter half angle θ2 of the paper sheet receiving angle θ is at the exit position E of the paper sheet B, especially when the rear blade is extremely close to the exit position E, the impeller 25
Depending on a, the paper sheet B cannot be held. Here, as described above, the paper sheet conveyance speed of the conveyor 10 and the rotation speed of the paper sheet guide means 20 are not synchronized, and the paper sheet B moves from a random position within the paper sheet reception angle θ to the impeller. Since the blade 25a enters between the blades 23a, 23a, the impeller 25a may not be able to hold the sheet B.

However, the paper sheet receiving angle θ'in the blades 23b, 23b positioned before and after the other impeller 25b mounted on the same rotary shaft 21 as the above-mentioned impeller 25a is formed between the impellers 25a blades 23a, 23a. When the paper sheet B enters from the exit position E at the position of the latter half angle θ2 where there is a possibility that the impeller 25a may be improperly held, since the paper sheet receiving angle θ is deviated by a half pitch, this impeller 25a In 25b, paper sheet B
The first half angle θ'that can securely hold the paper sheet B is
Is located at the exit position E of the front blade 23b, and is sandwiched between the tip of the front blade 23b and the bent portion 24b of the rear blade 23b.
Therefore, the paper sheet B is normally held by both impellers of the impellers 25a and 25b, and even if one impeller is improperly held, the other impeller is held.
It is possible to reliably prevent the situation in which both the impellers 25a and 25b cannot hold the paper sheet B together.

Thus, when the paper sheet B held by the paper sheet guiding means 20 as described above is displaced to a substantially horizontal state by the rotation of the paper sheet guiding means 20, its end face abuts on the guide wall 26. Since the sheet B is regulated by coming into contact with it and falls into the sheet stacking stacker 1, the sheet B is slightly bent by being held by only one of the impellers 25a and 25b. Also, since the posture is corrected by the guide wall 26, when falling into the sheet stacking stacker 1, the sheet B is in a substantially constant posture, and the stackability of the sheets is extremely good. Therefore, there is no displacement or reversal. In particular, as described above, in the case of storing the sheets in the sheet stacking stacker 1 with the front and back sides aligned by the transport conveyor 10, when the sheet B moves from the sheet guiding means 20 into the sheet stacking stacker 1, It is extremely important to prevent the paper sheet B from being reversed.

In the above-described embodiment, two impellers are provided on the rotary shaft, but, for example, three impellers are provided,
It is also possible to change the phase of the blade implantation position with respect to the impellers located on both sides of the impeller located in the center. In addition, the blade of one impeller is displaced from the blade of the other impeller by about a half pitch.
The point is that it is only necessary that the impeller on one side can be properly held by the impeller on the other side, and for example, the phase can be shifted by an angle that may cause an improper holding. May be.

[Effects of the Invention] As described above, according to the present invention, among the plurality of impellers provided on the rotating shaft, the blades of at least one impeller are phased with respect to the blades of the other impeller by a predetermined amount. Since it is configured to be planted in a shifted position, at least one of the impellers can surely hold the paper sheet supplied from the conveyor and send it to the paper sheet stacking stacker. There is no fear that the paper will be disturbed or inverted, and the stackability of the paper sheets will be extremely good.
