Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple sheet stacking device such as a reject stacker for error tickets in boarding pass issuing machines.

[0002]

2. Description of the Related Art Conventionally, as a simple reject stacker for stocking error tickets in a boarding pass issuing machine, for example, there is one as shown in FIG. This reject stacker includes a box-shaped stacker 1 for storing tickets, and an error ticket 2 that has been processed inside the boarding pass issuing machine.
It is composed of a pair of paper discharge rollers 3 for discharging and discharging the paper. Reference numeral 4 is a guide plate that also serves as a lid. As a result, after the trailing edge of the error ticket 2 comes out of the paper discharge roller 3, the error ticket 2 enters the stacker 1 due to the inertial force at the time of ejection, and passes over the stacker bottom surface 1a (or the surface of the error ticket 2 already stacked). It advances while rubbing and is stacked in the stacker 1.

[0003]

In such a reject stacker, if there is only one type of ticket to be handled and the stacker 1 is formed to have a length corresponding to the length of the ticket, the stackers are sequentially ejected without causing a jam. You can make it paper.

However, some boarding pass issuing machines handle ATB tickets (boarding passes), OCR tickets, and Mars tickets of different lengths in the same transport processing system. The ATB ticket is a standard ticket (long ticket) having a length of about 183 mm. The OCR ticket has a length of about 140 mm and the Mars ticket has a length of about 120 mm, which are shorter than the ATB ticket. Therefore, in the boarding pass issuing machine that handles such ticket types having different lengths, the ATB ticket, the OCR ticket, and the Marus ticket may be mixed as the error ticket 2.

When considering the stacking condition of the error tickets 2 under such a condition, a jam may occur. For example, as shown in FIG. 3, in the stacker 1, the error ticket 2a of the ATB ticket and the error ticket 2b of the OCR ticket are sequentially discharged and discharged, and the next error ticket 2 is discharged by the discharge roller 3. At the time of removal, the leading edge of the error ticket 2b hits the trailing edge of the already ejected error ticket 2b. As a result, a jam occurs in which the error ticket 2b is pushed up, or the error ticket 2 in the middle of discharging is abutted and the rear end side does not come out of the discharge roller 3 and stops. When such a ticket jam occurs, the processing operation as the boarding pass issuing machine must be stopped, and the processing performance is impaired.

[0006]

In a stacking apparatus for stacking paper sheets, which discharges several kinds of paper sheets having different lengths to a common stacker by a discharge roller, a biasing force is applied to the stacker bottom surface side. And a stopper plate that is movably arranged in the paper discharge space of the stacker and that restricts the discharge position of the short paper in the paper stack to the rear end side of the stacker.

[0007]

When the sheet to be discharged is long, the movably arranged stopper plate is pushed away and the sheet is discharged into the stacker. On the other hand, when the sheet to be discharged is a short sheet, the leading edge of the sheet hits the stopper plate, so that the sheet is discharged behind the stopper plate. That is, the paper discharge position in the stacker is the rear end side. As a result, in the case of any paper sheet, the trailing edge is stacked with the stacker trailing edge side, and the leading edge of the next discharged sheet is the trailing edge of the previously discharged sheet. You will never hit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. The present embodiment is applied to, for example, a stacking device which is a reject stacker in a boarding pass issuing machine, and the same parts as those shown in FIG. First, as an error ticket that can be discharged, A
Error ticket 2a due to TB ticket, error ticket 2 due to OCR ticket
b, an error ticket 2c made of a Marus ticket is assumed, and the length from the front end wall 1b to the rear end wall 1c of the stacker 1 is such that the longest error ticket 2a is not hindered from being stored.
Is set to about the length of.

A movable stopper plate 5 whose upper end is supported by the guide plate 4 is provided above the stacker 1. The lower end of this stopper plate 5 is the stacker bottom face 1
It has a length in contact with a and is disposed in an oblique state along the paper discharge direction of the error ticket 2 in the paper discharge space above the stacker 1. The stopper plate 5 has a leaf spring structure and is urged downward (on the stacker bottom surface 1a side) by an appropriate urging force due to its own spring property. The appropriate urging force means a urging force that does not cause a paper discharge load on the long error ticket 2a. Such a stopper plate 5 is arranged such that the lower end side thereof is positioned in consideration of the length plus α of the longer error ticket 2b among the short tickets from the rear end wall 1c of the stacker 1.

In such a configuration, for example, let us consider when the long error ticket 2a is discharged. In this case, the discharge roller 3
The leading edge of the error ticket 2a discharged from the stacker bottom surface 1
Heading toward the front end wall 1b while rubbing on a (or the surface of the error ticket 2 already stacked). The tip of the stopper plate 5 hits the stopper plate 5 in the middle of the process, but the movably supported stopper plate 5 escapes upward due to the error ticket 2 receiving the conveying force by the sheet discharge roller 3. The error ticket 2 is discharged onto the stacker bottom surface 1a without causing the error.

On the other hand, let us consider the time when the short error ticket 2b is discharged. In this case, the error note 2b discharged from the discharge roller 3 is shorter than the error note 2a because it is short and is discharged. Then, in a state where the rear end of the error ticket 2b passes through the discharge roller 3 and has only the inertial force and no carrying force, the front end of the error ticket 2b hits the stopper plate 5, so that the error ticket 2b is in the vicinity thereof. And stops on the bottom surface 1a of the stacker (or the surface of the error ticket 2 already stacked).
That is, the error ticket 2b is discharged to the rear side in the stacker 1 without the leading edge reaching the leading edge wall 1b side.

Also in the case of the shorter error ticket 2c, as in the case of the error ticket 2b, the tip of the error ticket 2c hits the stopper plate 5, so that the stacker bottom surface 1a (or the error already stacked) is generated in the vicinity thereof. Stop on the front of ticket 2. That is, the error ticket 2c is discharged to the rear side in the stacker 1 without the leading edge reaching the leading edge wall 1b side. However, since the error ticket 2c is shorter than the error ticket 2b, the trailing edge of the error ticket 2c is in a discharged state in which the trailing edge of the error ticket 2c is located closer to the leading edge than the trailing edge of the error ticket 2b.

Any error ticket 2 having a different length in this way
Even when a, 2b, or 2c is ejected, the paper is ejected into the stacker 1 in a state where the rear end of these tickets is at the position of the rear end wall 1c or a position slightly on the front end side thereof. The leading edge of the error ticket 2 to be discharged next does not hit the trailing edge of the already stacked error ticket 2. Therefore, the leading edge of the error note 2 to be discharged next advances smoothly while rubbing on the surface of the already stacked error note 2 and is stacked in the stacker 1 without causing a jam. Also for this purpose, the stopper plate 5 may be added, so that it can be realized at low cost.

Since the tip (lower end) side of the stopper plate 5 is displaced upward as the number of stocked error tickets 2 in the stacker 1 increases, the stacking restriction position for short notes does not change much. Further, the position where the stopper plate 5 is arranged does not need to be so strict, and the point is that the length L from the rear end wall 1c, which is longer in the short ticket, can be discharged into the stacker 1 without hindrance (book. In the embodiment, at least the length of the error ticket 2b) and the trailing end of the error ticket 2 to be ejected may be regulated so as not to be too far from the rear end wall 1c.

Further, in this embodiment, the stopper plate 5 having the leaf spring structure is used, and the biasing force is given by its own spring property.
The stopper plate having a simple plate structure is provided with a proper biasing force by a torsion spring or the like provided at its fulcrum portion, and the stacker bottom surface 1
It may be biased to the a side.

Next, a second embodiment of the present invention will be described with reference to FIG. The present embodiment is applied to, for example, a stacking device that is a temporary storage unit for temporarily storing ATB tickets and OCR tickets in a mixed state in a boarding pass issuing machine. This is because this temporary storage unit temporarily stores the ATB ticket 6a and the OCR ticket 6b, which are simultaneously taken in from the take-in port, in the stacker 7, and the person in charge takes out the stacker 7 from the stacker 7 for subsequent processing. It is for offering. That is, when issuing the ATB ticket 6a or the like, it is necessary not only to simply print the data by the printing section but also to magnetically record and issue the magnetic stripe on the magnetic stripe by the magnetic recording section, so that the ticket is issued per sheet. Since it takes a long time, the stacker 7 is temporarily stored. In such a temporary storage part, the stacker 7 is disposed in a vertically inclined state as shown in FIG. A pair of paper discharge rollers 8 is disposed on the wall 7c) side. As a result, the ticket 6a or 6b is discharged and discharged into the stacker 7 from the bottom to the top. 9 is a guide plate.

A movable stopper plate 10 supported by the guide plate 9 with respect to the stacker 7 is provided. The stopper plate 10 has a length such that the leading end thereof contacts the bottom surface 7a of the stacker, and is arranged in the paper discharge space in the stacker 7 in an oblique state along the paper discharge direction of the bills 6a and 6b. The stopper plate 10 has a leaf spring structure and is urged toward the stacker bottom surface 7a by an appropriate urging force due to its own spring property. The appropriate urging force means an urging force that does not cause the paper discharge load of the longer ATB ticket 6a. Such a stopper plate 10 is
The stacker 7 is arranged at a position in consideration of the length plus α of the short OCR ticket 6b from the rear end wall 7c.

In such a structure, let us consider, for example, when the longer ATB ticket 6a is discharged. In this case, the front end side of the ATB bill 6a discharged from the paper discharge roller 8 moves toward the front end wall 7b side while rubbing the stacker bottom surface 7a (or the surface of the already stacked bills 6). The tip of the stopper plate 10 hits the stopper plate 10 in the middle of the process, but the movably supported stopper plate 10 escapes to the left in the figure by the ticket 6 receiving the conveying force by the paper discharge roller 8, so that the stopper plate 10 is discharged. The ticket 6 is discharged along the stacker bottom surface 7a without a paper load.

On the other hand, let us consider the time of discharging the short OCR bill 6b. In this case, since the OCR bill 6b discharged from the discharge roller 8 is short, the OCR bill 6b is discharged in a form discharged as compared with the ATB bill 6a. Then, the front end of the OCR ticket 6b hits the stopper plate 10 in a state where the rear end of the OCR ticket 6b passes through the paper discharge roller 8 and has only inertial force and no carrying force. Therefore, the OCR ticket 6b is discharged to the rear end wall 7c side in the stacker 7 without the front end reaching the front end wall 7b side.

Even when any of the sheets 6a or 6b having different lengths is discharged as described above, the sheets are discharged into the stacker 7 with the rear ends of these sheets at the position of the rear end wall 7c. Therefore, the leading edge of the ticket 6 to be discharged next does not hit the trailing edge of the already stacked ticket 6. Therefore, the leading edge of the next discharged sheet 6 advances smoothly while rubbing on the surface of the already stacked sheet 6 and is stacked in the stacker 7 without causing a jam.

In this embodiment, since the stacker 7 is provided in a vertical shape, even if the short OCR bill 6b is discharged into the stacker 7 by the discharge roller 8, the stacker 7 basically operates. Can be discharged by its own weight so that the rear end is aligned with the rear end wall 7c. However, static electricity is temporarily generated between the OCR ticket 6b discharged toward the front end wall 7b and the ATB ticket 6a already stacked. Sometimes it happens that the tickets stick together and they do not go down, so relying on their own weight is not reliable.
In this respect, the tip wall 7 in the case of the OCR ticket 6b in this embodiment.
The stopper plate 10 is forcibly prevented from being discharged up to b, so that the stacking operation becomes reliable.

Also in this embodiment, instead of the stopper plate 10 having the leaf spring structure, a stopper plate having a simple plate structure is used, and an appropriate biasing force is applied by a torsion spring or the like provided at the fulcrum portion of the stopper plate 10a. It may be biased to the side.

In each of these embodiments, the boarding pass issuing machine has been described as an example of application to a stack device that handles ATB tickets and the like as paper sheets, but the present invention is not limited to such a device, and different lengths are used. The same applies as long as the sheets are stacked in a state where they can be mixed.

[0024]

According to the present invention, in a stacking apparatus for stacking paper sheets, which discharges several kinds of paper sheets having different lengths to a common stacker by a discharge roller, the urging force toward the bottom surface of the stacker is applied. Since a stopper plate is provided that is provided movably in the paper sheet discharge space of the stacker and restricts the paper discharge position of the short paper sheets in the paper sheet to the rear end side of the stacker,
When a short sheet is ejected, the stopper plate can be used to restrict the ejection of the long sheet to the rear end side in the stacker without deteriorating the stackability. It is possible to prevent the leading edge from hitting the trailing edge of the sheet that has been ejected first to cause a jam, and it is possible to improve the stacking performance with a simple structure.
