Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet aligning / conveying device for aligning paper sheets such as banknotes conveyed in a device to a predetermined state by aligning them to a reference surface.

[0002]

2. Description of the Related Art An example of a conventional sheet aligning and conveying apparatus is disclosed in Japanese Utility Model Publication No. 3-16841.

According to the above-mentioned publication, a plurality of rows of aligner rollers are provided for an aligner drum, and even if a paper sheet having a width narrower than a regular width such as a half-folded bill is conveyed. The aligner rollers are arranged so that they can be held and conveyed without fail.

All the aligner rollers are supported by the flange of the aligner drum in a direction inclined to the direction in which the paper sheets are brought close to each other, so that any paper sheet always has a function of bringing it toward the flange side.

[0005]

However, in the above-mentioned prior art, since the aligner roller is always inclined and in contact with the conveying direction of the sheet, the sheet to be conveyed should be brought closer to the flange. The power to do is always added.

Therefore, even when the paper sheet whose edge is moved closer to the flange in advance is conveyed, the paper sheet is pressed against the flange, which causes wrinkles and jamming. There was a problem of causing it.
In addition, even if the banknotes that were insufficiently squeezed before they entered the device were squeezed at an early stage, the above-mentioned force would still be applied, causing the same problem (occurrence of wrinkles and jamming). )was there.

In view of the above, the present invention provides a width-shifting force (a power for shifting the width of the paper sheets. A force that does not apply in the direction orthogonal to the transport direction on the surface) is reliably applied, and only the paper sheets that are not sufficiently width-wise aligned are reliably aligned, thereby preventing the occurrence of jamming and the like. An object of the present invention is to provide an aligning and conveying device.

[0008]

In order to achieve the above object, the present invention has an aligner drum which has a flange serving as a reference surface for conveying paper sheets at one end and which rotates in a fixed direction.
An aligner roller that is provided in contact with the outer peripheral surface of the aligner drum and is rotatably supported between a parallel position parallel to the aligner drum and an inclined position that is inclined in a direction to bring the conveyed paper sheet closer to the flange. And a switching means for switching the position of the aligner roller, and a width-shifting detection means arranged in proximity to the flange for detecting the widthwise shifting of the paper sheets.

According to a second aspect of the present invention, an aligner drum having a flange serving as a reference surface for transporting paper sheets on one side and rotating in a fixed direction, and a contact position abutting the outer peripheral surface of the aligner drum are separated from each other. A parallel roller that is movably supported between the aligner drum and a separate position, and a parallel roller whose rotary shaft is substantially parallel to the rotary shaft of the aligner drum, and a separate position that separates from a contact position that contacts the outer peripheral surface of the aligner drum. And an aligner roller which is movably supported between the aligner roller and the aligner roller and is inclined in a direction approaching the flange along the rotation direction of the aligner drum, and the parallel roller is positioned at the contact position and the aligner roller is positioned at the separated position. Switching means for switching between a straight traveling state in which the parallel rollers are positioned at a separating position and a width-shifting state in which the aligner rollers are positioned at a contact position, and the flag. Disposed proximate to di-, is characterized by comprising a lateral move detecting means for detecting a lateral move of the sheet.

[0010]

According to the first aspect of the present invention, if the width-shifting detection means detects that the sheets fed around the aligner drum are not pushed to the flange, the aligner roller takes an inclined position and the sheets are moved. Is conveyed diagonally in the direction of approaching the flange.

When it is detected by the width-shifting detection means that the paper sheets are brought close to the flange, the aligner roller takes a parallel position and the paper sheets are conveyed straight.

According to the second aspect of the present invention, if the width-shift detecting means detects that the paper sheets fed around the aligner drum are not pushed to the flange, the aligner roller is brought into contact with the aligner drum and the parallel roller is moved. And the paper sheets are held by the aligner drum and the aligner roller, and conveyed obliquely in the direction toward the flange.

When it is detected by the width-shifting detection means that the paper sheets have been moved to the flange, the parallel rollers are brought into contact with the aligner drum and the aligner rollers are separated from each other to move the paper sheets to the aligner drum and the parallel rollers. Hold by and convey straight.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show the first embodiment of the present invention. FIG. 1 shows the front side, FIG. 2 shows the side face during width adjustment, and FIG. 3 shows the side face during direct delivery. The case where it is used as a paper sheet in a banknote transport system is shown. In this embodiment, an aligner drum 1 having a flange 1a on one side is rotatably provided, and is rotated counterclockwise in FIG. 2 by a driving means (not shown). The opposite side of the aligner drum 1 is surrounded by a guide plate 2 around a half circumference thereof, and the fed bills are arranged along the aligner drum 1.

One aligner roller 3 and two parallel rollers 4 and 4 sandwiching the aligner roller 3 are arranged so as to face an exposed portion of the aligner drum 1 which is not covered by the guide plate 2. The roller is supported so that its peripheral surface can swing between a contact position where it contacts the aligner drum 1 and a separated position where it separates. The parallel rollers 4 and 4 are parallel to the aligner drum 1, but the aligner roller 3 is inclined along the rotation direction of the aligner drum 1 toward the flange 1a.

The position of the aligner roller 3 can be switched by a switching mechanism 5. That is, the aligner roller 3 is rotatably supported by the support metal fitting 7 attached to one end of the first support member 6, and the other end of the first support member 6 is laterally projected and connected to the switching mechanism 5 so as to be parallel. The rollers 4 and 4 are rotatably supported by a U-shaped support metal fitting 9 at one end of the second support member 8, and the other end of the second support member 8 is laterally moved like the first support member 6. It is connected to a switching mechanism 5 which is projected and is common to the aligner roller 3.

The switching mechanism 5 comprises a solenoid 10, a slide member 11, and first and second swinging members 12 and 13. First rocking member 12 and second rocking member 1

In FIG. 2, the solenoid 10 is not excited,
The slide member 11 is shown in a state of being pulled down by the tension spring 17. In this state, the aligner roller 3 is pressed against the aligner drum 1, and the parallel rollers 4 and 4 are placed at positions apart from the aligner drum 1.
When the solenoid 10 is excited and the slide member 11 is pulled up, the first swinging member 12 receives a clockwise rotation about the shaft 15 in FIG. 2 so that the aligner roller 3 separates from the aligner drum 1 and the second swinging motion occurs. When the member 13 is rotated counterclockwise, the parallel rollers 4 and 4 are pressed against the aligner drum 1 (FIG. 3). When the solenoid 10 is de-energized, the tension spring 17 is urged to return to the state of FIG.

A first sensor S ₁ for detecting the presence of banknotes is arranged on the upstream side of the aligner roller 3 and the parallel rollers 4, 4 at a position close to the flange 1a. The first sensor S ₁ is of the bill to be conveyed around the aligner drum 1, or along the flange 1a, or is to detect what is conveyed very close. The second sensor S ₂ is provided at a position downstream of the aligner roller 3 and the parallel rollers 4 and 4 and close to the flange 1a.
Is arranged. The second sensor S ₂ is configured to detect that the bill is transversely shifting the downstream side of the aligner rollers 3 and parallel rollers 4, 4, and detects the passage of the bill.

Next, the operation of the above embodiment will be described.

In the standby state, the solenoid 10 is not excited and the aligner roller 3 moves the aligner roller 3
Is pressed against. The aligner drum 1 is rotated counterclockwise in FIG. 2, and the aligner roller 3 is also driven to rotate. The banknote transported by the upstream transport mechanism (not shown) is inserted between the aligner drum 1 and the guide plate 2 and is curved so as to be wound around the aligner drum 1.

The conveyance state of bills on the peripheral surface of the aligner drum 1 is shown in plan view in FIGS. The upward direction in these drawings is the upstream side in the conveyance path, the flange 1a is located at the left end, and the first sensor S
₁ and a second sensor S ₂ are arranged. And Figure 4
Shows the time when the aligner roller 3 is pressed against the aligner drum 1 (the parallel rollers 4, 4 are separated from the peripheral surface of the aligner drum 1), and FIG.
Indicates the time of direct feeding when it is pressed against the aligner drum 1 (the aligner roller 3 is separated from the peripheral surface of the aligner drum 1).

When the bill (A1) sent in a state where the bill is sufficiently moved to the flange 1a reaches the first sensor S ₁ (A2), the bill is detected by the first sensor S ₁ and the solenoid 10 is turned on. Be excited. When the solenoid 10 of the switching mechanism 5 is excited, the slide member 11 is pulled upward, and the first and second swing members 12 and 13 rotate clockwise in FIG.
The aligner roller 3 is separated from the aligner drum 1 by the rotation of the parallel roller 4,
4 is pressed against the aligner drum 1 (FIG. 3). The bills are nipped and conveyed by the aligner drum 1 and the parallel rollers 4 and 4 and conveyed straight (A3 to A4). Therefore, the bills that have been sufficiently pushed to the flange 10a are normally conveyed without being jammed by the excessive aligning force of the aligner roller 3.

The end of the bill passes the second sensor S ₂ (A
5) When the second sensor S ₂ detects “no banknote”, the excitation of the solenoid 10 is released, and the aligner roller 3 returns to the standby state in which it is pressed against the aligner drum 1.

When the bill is conveyed in a state where it cannot be sufficiently brought close to the flange 1a (B1), even if the bill reaches the position of the first sensor S ₁ (B2), the bill is not detected by the sensor S ₁ so that the solenoid is used. 10, the aligner roller 3 is not excited, and the aligner roller 3 is kept in the standby state (FIG. 2).
Therefore, the bills are nipped and conveyed by the aligner drum 1 and the aligner roller 3. Since the aligner roller 3 is attached so as to be inclined with respect to the conveying direction, the bill is gradually moved closer to the flange 1a (B3 to B4). Banknotes were received sufficiently flange 1a, the second sensor S ₂ detects the "bill present", the solenoid 10 is energized, with the aligner roller 3 is separated from the aligner drum 1 with the excitation of the solenoid 10, parallel Since the rollers 4 and 4 are pressed against the aligner drum 1 (FIG. 3), the banknotes are held by the parallel rollers 4 and 4 and the aligner drum 1 and conveyed straight (B4 to B5). Therefore, even if the banknote has not been sufficiently moved to the flange 1a at the time of entry, the aligner roller 3 can be used after the width adjustment is completed.
Therefore, the paper is normally conveyed without being jammed due to the excessive lateral pulling force.

When the end of the bill passes the second sensor S ₂ and the sensor S ₂ detects "no bill", the solenoid 1
The excitation of 0 is released and it returns to the standby state (FIG. 2).

6 to 8 show a second embodiment of the present invention. Also in this embodiment, the aligner drum 1, the flange 1a, the guide plate 2, the first and second sensors S ₁ , S
Regarding ₂ , the structure is almost the same as that of the first embodiment.

An aligner roller 3 is arranged above the aligner drum 1 with their peripheral surfaces in contact with each other. The aligner roller 3 is rotatably supported by an L-shaped support plate 18, and the support plate 18 is rotatably supported about a rotation shaft 19 extending in the vertical direction. A rotating member 20 is attached near the upper end of the rotating shaft 19, and the rotating member 20 is biased clockwise by a tension spring 21 in FIG. A solenoid 22 is attached to the solenoid 22 in a direction opposite to the tension spring 21, and these constitute a switching mechanism 5.

Therefore, when the solenoid 22 is not excited, the rotary member 20 is placed in the state shown in FIG. At this time, the aligner roller 3 is held in a state of being inclined with respect to the banknote transport direction (inclining so that the downstream side in the transport direction approaches the flange 1a). Then, when the solenoid 22 is excited, the rotating member 20 is rotated clockwise, and the state shown in FIG. 8 is reached, and the aligner roller 3 contacts the aligner drum 1 while being parallel to the aligner drum 1.

Next, the operation of the above embodiment will be described.

During standby, the solenoid 22 is not excited and is in the state shown in FIG.

When the banknotes that have been sufficiently widened are conveyed, the leading edge of the banknote is detected by the first sensor S ₁ . When the first sensor S ₁ detects a bill, the solenoid 22 is excited and the state shown in FIG. 8 is reached, and the bill is held between the aligner roller 3 and the aligner drum 1. At this time, since the aligner roller 3 is in the rotation position parallel to the aligner drum 1, the bill is conveyed straight. Therefore, the bills that have been sufficiently pushed to the flange 1a are normally conveyed without being jammed by the excessive aligning force of the aligner roller 3.

When the end of the bill passes the second sensor S ₂ and the sensor S ₂ detects "no bill", the solenoid 2
The excitation of No. 2 is released and it returns to the standby state (FIG. 7).

When a bill that has not been sufficiently widened is conveyed, the leading edge of the bill is not detected by the first sensor S ₁ , so the bill is held between the aligner roller 3 and the aligner drum 1 in the state of FIG. Are transported. At this time, since the aligner roller 3 is inclined, the banknotes are conveyed while being gradually moved to the flange 1a. When the banknotes have been sufficiently widened and the first sensor S ₁ or the second sensor S ₂ detects the banknotes, the solenoid 22 is excited and the state shown in FIG. 8 is obtained. In this state, the aligner roller 3 is in a position parallel to the aligner drum 1, so that the banknotes sandwiched between the aligner roller 3 and the aligner drum 1 are conveyed straight. Therefore, when entering, the flange 1a is sufficiently
Even when the banknotes that have not been moved to the side are received, after the width-shifting is completed, the aligner rollers 3 do not cause jamming due to an excessive force of the width-shifting and are normally transported.

When the end of the bill passes the second sensor S ₂ and the sensor S ₂ detects "no bill", the solenoid 2
The excitation of No. 2 is released and it returns to the standby state (FIG. 7).

9 to 11 show a third embodiment of the present invention. Also in this embodiment, the aligner drum 1, the flange 1a, the guide plate 2, the first and second sensors S ₁ ,
The S ₂ has almost the same structure as that of the first embodiment.

Above the aligner drum 1, a parallel roller 4 and an aligner roller 3 are rotatably supported by both ends of a single support member 23. The parallel roller 4 is aligned with the aligner drum 1.
The aligner roller 3 is inclined parallel to the flange 1a along the rotation direction of the aligner drum 1. The support member 23 is a rotary shaft 2 fixed at the center.
4 is rotatable about the parallel roller 4 and the position where the parallel roller 4 is pressed against the aligner drum 1 and the aligner roller 3 is separated from the aligner drum 1.
Is separated from the aligner drum 1 and the position where the aligner roller 3 is pressed against the aligner drum 1 can be switched. The rotating member 25 attached to the other end of the rotating shaft 24 is a tension spring 26. Figure 9
At, the aligner roller 3 is biased in the counterclockwise direction and is pressed against the aligner drum 1. Further, a solenoid 27 is attached so as to resist the bias of the tension spring 26, and when the solenoid 27 is excited, the rotating member 25 is biased in the clockwise direction in FIG. It is pressed against the aligner drum 1.

Next, the operation of the above embodiment will be described.

During standby, the solenoid 27 is not excited, the aligner roller 3 is pressed against the aligner drum 1, and the parallel roller 4 is separated.

When the banknotes that have been sufficiently shifted in width are conveyed, the leading edge of the banknote is detected by the first sensor S ₁ . When the first sensor S ₁ detects a bill, the solenoid 27 is excited and the parallel roller 4 is pressed against the aligner drum 1. The banknote is held between the parallel roller 4 and the aligner drum 1 and conveyed straight. The end of the bill is the second sensor S
_When the sensor S ₂ passes “ ₂ ” and detects “no banknote”, the solenoid 27 is deenergized and returns to the standby state. Therefore, the banknotes that have been sufficiently moved to the flange 1a are normally conveyed without being jammed by the aligner roller 3 due to excessive width-shifting force. End of the bill passes through the second sensor S _2, the second sensor S ₂ detects the "no bill", the excitation of the solenoid 27 is released, the aligner roller 3 is pressed against the aligner drum 1, parallel roller 4 It returns to the separated state and prepares for the next bill.

When a banknote that has not been sufficiently widened is conveyed, the leading edge of the banknote is not detected by the first sensor S ₁ , so the aligner roller 3 is kept pressed against the aligner drum 1 and the banknote is aligned. The roller 3 and the aligner drum 1 sandwich and convey the sheet. The banknotes are gradually moved to the flange 1a side by the action of the aligner roller 3. When the banknotes are sufficiently widened and the first sensor S ₁ or the second sensor S ₂ detects the banknotes, the solenoid 27 is excited, the aligner roller 3 is separated from the aligner drum 1, and the parallel roller 4 is moved to the aligner drum 1. It is pressed. The banknote is held between the parallel roller 4 and the aligner drum 1 and conveyed straight. Therefore, even if the banknotes that have not been width-shifted at the time of entry are sufficiently moved to the flange 1a, they are normally conveyed without being subjected to excessive width-shifting force and causing jamming.

The end of the bill passes through the second sensor S _2, the second sensor S ₂ detects the "no bill", the excitation of the solenoid 27 is released, the aligner roller 3 is pressed against the aligner drum 1, parallel The roller 4 returns to the separated state and prepares for the next bill.

[0044]

As described above, according to the present invention, it is possible to reliably align the paper sheets that are not sufficiently aligned, and the paper sheets that have been aligned from the beginning and the width in the middle. Since the width-shifting force is not applied to the paper sheets that have been moved together, it is possible to suppress the occurrence of jamming and the like, and to prevent the paper sheets from wrinkling.
