Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet feeding device which stacks and stores tickets and sends them out in order from the uppermost ticket.

[0002]

2. Description of the Related Art Conventionally, a sheet feeding device of this type is shown in FIG.
As shown in FIG. 3, it is used for feeding a ticket 1 such as a magnetic card. This ticket 1 has a rectangular shape that is long in the sending direction, and has a magnetic stripe layer formed on one edge side orthogonal to the sending direction.
The thickness of one edge side is thicker than the thickness of the other edge side.

In the conventional paper feeding device for feeding the ticket 1 as described above, an elevating and lowering support base 3 for supporting the laminated ticket is provided at the bottom of a case body 2 for accommodating the ticket 1 so as to be able to ascend and descend. A plurality of screw holes 6 are formed in the side projections 5 of the elevating arms 4 attached to the table 3, and screw shafts 7 axially supported in the screw holes 6 of the elevating arms 4 are screwed together. Then, the plurality of screw shafts 7 are rotated to raise the elevating support base 3, and the uppermost ticket 1 stacked and supported on the elevating support base 3 is positioned at the delivery fixed position.

Then, the delivery roller 8 disposed above the case body 2 and on the end side in the ticket delivery direction is the uppermost ticket 1.
The uppermost ticket 1 is pushed out from inside the case body 2 by the rotation of the feeding roller 8.

[0005]

In the sheet feeding device of the conventional structure described above, the elevating support base 3 and the feeding roller 8 are arranged in parallel, while the ticket 1 has one edge side when a large number are stacked. The sheet is inclined to the upper side, and the delivery roller 8 comes into one-side contact with one side strongly contacting the upper surface of the stacked uppermost ticket 1. When the ticket 1 is fed out while the delivery roller 8 is in one-side contact, the ticket 1 is likely to be swayed to the left and right with a contact point with one side of the peripheral surface of the delivery roller 8 as a fulcrum, and the ticket 1 is delivered. The rear side in the direction may get over the upper end of the side wall of the case body 2 and project laterally, and the ticket 1 may be delivered in a skewed state.

The present invention has been made in view of the above point, and regulates the skew of the ticket delivered from the ticket storage portion, and delivers the ticket in the same fixed posture as when the sheets are stacked in the ticket storage portion. It is intended to provide a paper feeding device that can be fed in any direction.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a ticket storage unit having an elevating and lowering support for stacking and supporting the tickets and positioning the uppermost ticket at a fixed upper delivery position, and a position above the ticket storage unit. And a delivery roller that is provided on the end side in the ticket delivery direction and that delivers sequentially from the uppermost ticket that is stacked and stored in the ticket storage portion, and a delivery roller that is provided on the side portion of the ticket storage portion in the ticket delivery direction that A pair of transport rollers for sandwiching and transporting the ticket sent out from the ticket storage unit, and a position above the ticket storage unit and within a length of the transport roller position from the position of the transport roller for storing the ticket. And a pressing roller that comes into pressure contact with the upper surface of the uppermost ticket that is stacked and stored in the stack.

[0008]

According to the present invention, the uppermost ticket is delivered in the ticket delivery direction by the rotation of the delivery roller that contacts the upper surface of the uppermost ticket stacked in the ticket storage portion.

At this time, since the pressing roller and the pressing roller are in pressure contact with the upper surface of the ticket to be sent out, for example, the sending roller is only one-sided against the upper surface of the ticket, and the contact point of the sending roller serves as a fulcrum for the ticket. Even if a swaying force acts on the left and right sides that are orthogonal to the ticket sending direction, the swaying of the ticket is regulated by the pressing roller that presses against the ticket. Therefore, the sent-out ticket has its sending attitude regulated at the two contact positions of the sending roller and the pressing roller, and is sent in the ticket sending direction with the same fixed attitude as when the stacked sheets are stored in the ticket storage section.

Further, in the state where the pressing roller is in contact with the sent-out ticket, the sending-out front end portion of the ticket is clamped by the conveying roller. Therefore, even if the sent-out ticket comes off the pressing roller, the ticket remains in a fixed posture. It is sent out in the ticket sending direction.

An elevating support base 31 is attached on the elevating arm 42. The side plate portion 24 on the other side of each of the lifting arms 42
A boss portion having a screw hole 43 at the end protruding outward from
44 is formed, and the screw hole 43 of this boss portion 44 is
It is screwed into each 45. Each screw shaft 45 includes a bearing 47 provided on a mounting table 46 on which the bottom surface of the case body 22 is mounted.
And a bearing 48 provided on a support plate portion 24a that is bent outward from the upper end of the side plate portion 24 on the other side at a substantially right angle, and is rotatably supported in a vertical state.

Then, the elevating mechanism 41 includes the screw shafts 45
The rotation driving force of the electric motor (not shown) is transmitted to the pulley 49 attached to the lower end of the belt by the belt (not shown), and the screw shafts 45 are interlocked with each other to raise the elevating support base 31 via the elevating arms 42, The uppermost ticket 11 laminated and supported on the elevating and lowering support 31 is positioned at a predetermined delivery fixed position.

Further, at the position near the other end of each elevating arm 46 in the ticket storage portion 21, an adjusting screw capable of projecting and retracting upward
A screw 50 is screwed, and is supported by the adjusting screw 50 such that the other edge side inclines upward from one edge side of the elevating support base 31. The inclination of the elevating support base 31 is set so that the tickets 11 at approximately half the positions of the tickets 11 stacked on the elevating support base 31 are substantially horizontal to the elevating support base 31.

Further, as shown in FIGS. 1 and 2, the uppermost ticket 11 stacked in the ticket storage portion 21 is sequentially arranged above the ticket storage portion 21 and at one end side in the ticket sending direction. A delivery roller 51 that delivers through the delivery port 26 is provided, and
The delivery roller 51 is provided at a side position of the ticket delivery port 26 in the ticket delivery direction.
A pair of upper and lower transport rollers 52 and 53 for sandwiching and transporting the ticket 11 delivered through the ticket delivery port 26 are rotatably arranged.

The delivery roller 51 is swingably supported by a support frame 54 about a rotation shaft 52a of an upper conveyance roller 52 as a fulcrum. The upper conveyance roller 52 has a rotation shaft 52a as a bearing provided on a chassis (not shown). Is rotatably supported at a fixed position, and the lower conveying roller 53 is urged by a spring so as to come into pressure contact with the upper conveying roller 52 and is rotatably supported.

The support frame 54 is formed in a substantially U-shaped cross section in which the sending roller 51 and the conveying roller 52 are arranged between the both side plate portions 55, and the one end side of the both side plate portions 55 is rotated by the rotation shaft 52a of the conveying roller 52. A bearing portion 56 that is freely fitted is formed, and a bearing portion 57 that rotatably supports the rotating shaft 51a of the feed roller 51 is formed on the other end side. Therefore, the support frame 54 is supported so as to be vertically swingable on the delivery roller 51 side with the rotation shaft 52a as a fulcrum.

A spiral spring 58 for urging the support frame 54 upward is connected to the support frame 54, and the support frame 54 is also supported.
The solenoid is attached to the pin 59 protruding from the side plate 55 on one side of the 54.
A coil-shaped spring 62 stretched between 60 and a plunger 61 is connected. When the solenoid 60 is not excited, the plunger 61 projects upward and the spring 62
Since the elastic force of the spring 58 is smaller than the elastic force of the spring 62, the support frame 54 swings upward, and the delivery roller 51 is positioned at the delivery fixed position. When the solenoid 60 is excited, the plunger 61 is pulled downward, and the tension elastic force of the spring 62 becomes stronger than the elastic force of the spring 58, as shown in FIG. Oscillates downward, and the delivery roller 51 comes into pressure contact with the upper surface of the stack uppermost ticket 11 located at the delivery fixed position.

As shown in FIG. 2, pulleys 63 and 64 are attached to the rotary shafts 51a and 52a of the rollers 51 and 52, and an endless belt 65 is stretched between the pulleys 63 and 64. Then, when the rotating shaft 52a is rotationally driven in the ticket conveying direction (the arrow direction in the drawing) by an electric motor (not shown), the conveying roller 52
Is rotated and the delivery roller 51 is
Are rotated in the same direction. The lower transport roller 53 is driven to rotate with respect to the upper transport roller 52.

As shown in FIG. 1, the upper and lower guide plates 66 and 67 are provided on the ticket delivery sides of the upper and lower transport rollers 52 and 53, respectively.
A transport passage 68 for transporting 11 to the downstream side is formed.

Further, as shown in FIGS. 1 and 2, a bill upper surface position detecting portion 71 is arranged at a position close to the feeding roller 51 on the side opposite to the bill feeding direction. In the bill upper surface position detecting portion 71, a swing body 73 is swingably attached to a support shaft 72 supported by a chassis (not shown), and an arm portion 74 and a detection lever portion 75 are attached to the swing body 73 in the direction of the delivery roller 51. A detection roller 76 is rotatably attached to one side of the arm portion 74 in parallel with the delivery roller 51 and the like.
Furthermore, a bracket 77 supported by a chassis (not shown)
A detection circuit is attached to a printed circuit board 78, and a not-shown ticket upper surface position detection sensor for detecting the rising swing position of the tip end portion of the detection lever 75 is attached to the printed circuit board 78. This ticket top surface position detection sensor is composed of a proximity sensor, an optical sensor, a micro switch, and the like.

When the oscillating body 73 oscillates so that the detecting roller 76 descends due to its own weight, the ticket upper surface position detecting section 71 detects the upper surface position of the detecting lever 75 which swings downward together with the oscillating body 73. The sensor stops detecting. As shown in FIG. 3, the raising / lowering mechanism 41 is driven based on this detection to raise the support 31 on which the tickets 11 are stacked. Further, the upper surface of the ticket 11 lifted by the lifting mechanism 41 contacts the detection roller 76,
The swinging body 73 swings so that the detection roller 76 rises,
When the uppermost ticket 11 is raised to the sending home position, the rocker
The detection lever 75, which swings up and swings together with 73, is detected by the ticket upper surface position detection sensor. The drive of the elevating mechanism 41 is stopped based on this detection.

Further, as shown in FIG. 1, at the position above the ticket storage portion 21 and at the position L2 within the length L1 of the ticket 11 in the ticket sending direction from the position of the transport rollers 52 and 53, the ticket 11 is placed. A pressing roller 81 which is also used as a skew prevention means and a presence / absence detection means for the ticket 11 is provided.

The pressing roller 81 is made of a rubber material having a high coefficient of friction, and has a rotary shaft 81a at one end between the side plate portions 83 of the support frame 82 having a substantially U-shaped cross section as shown in FIGS. The support frame 82 is rotatably supported and both side plate portions 83 of the support frame 82 are supported.
The other end side is pivotally supported by a support shaft 85 protruding from one side surface of the mounting frame 84. Therefore, the support frame 82 is supported so that the presser roller 81 side can swing vertically with the support shaft 85 as a fulcrum.

A spiral-shaped spring 86 is attached to the support shaft 85. One end of the spring 86 is engaged with the support frame 82 and the other end is engaged with the attachment frame 84, so that the support frame 82 is The pressing roller 81 is urged to swing downward, and the pressing roller 81 is pressed against the upper surface of the stacking uppermost ticket 11 by the urging force of the spring 86.

A lever 87 is attached to the upper surface of the support frame 82, and a substantially L-shaped lever portion 88 of the lever 87 protruding from the support frame 82 in the other direction is brought into contact with a stopper portion 89 of the attachment frame 84. The downward swing is restricted. In addition, the elevating support table 31 is raised until the last one ticket 11 is positioned at the sending home position,
When the last one of the tickets 11 is sent out and there is no ticket 11 on the lift support base 31, the presser roller 81 descends into the detection window hole 32 of the lift support base 31 and the lowered position of the presser roller 81. The lever portion 88 comes into contact with the stopper portion 89.

The mounting frame 84 has a substantially U-shaped cross section, the other side portion is fixed to the chassis 90 with screws 91, and a cutout portion 92 is formed from the upper surface to one side surface.
The stopper portion 89 is formed at the edge of the.

A ticket presence / absence detection switch is provided on one side of the mounting frame 84.
93 is attached, and the operator of this ticket presence / absence detection switch 93
94 is arranged in the lower swing region of the lever portion 88. When the presser roller 81 is in contact with the ticket 11 stacked on the lift support table 31 and is being pushed up, the lever portion 88 swings upward and the operator 94 is not pushed down. The switch 93 is turned off and the presence of the ticket 11 is detected. On the other hand, when all the tickets 11 on the lift support base 31 are sent out and the presser roller 81 is lowered into the detection window hole 32 of the lift support base 31, the lever is released. The portion 88 swings downward, the operator 94 is pushed down, the ticket presence / absence detection switch 93 is turned on, and the absence of the ticket 11 is detected.

Next, the operation of this embodiment will be described.

When the ticket 11 is stored in the ticket storage portion 21, an elevating mechanism 41 forms an elevating and lowering support base forming the bottom surface of the ticket storage portion 21.

A ticket (11) is stacked on the ticket (11) with the thick magnetic stripe layer (12) side aligned with one edge side.

After the ticket 11 is stored, the elevating mechanism 41 raises the elevating and lowering support base 31, and when the upper surface of the stacked uppermost ticket 11 comes into contact with the detection roller 76 and the pressing roller 81, the rollers 76 and 81 are pressed. The tickets 11 accumulated by the rollers 11 are pressed against the lift support base 31 to reduce the gap between the tickets 11, and
When 6 and 81 are pushed up and the uppermost ticket 11 is raised to the sending home position, the uppermost ticket 11 is raised to the sending home position via the detection roller 76.
Is detected and the ascending / descending mechanism 41 stops the ascending / descending of the ascending / descending support base 31.

When the ticket 11 is stored, the pressing roller 81 is pushed up by the ticket 11, the ticket presence / absence detection switch 93 is turned off, and the presence of the ticket 11 is detected. Furthermore, the lifting support base 31 is adjusted so that the other edge side is adjusted so that the one edge side is the lower side.
Since it is inclined upward by the pressing roller 81 which is always in contact with the ticket 11 and the delivery roller 51 which is in contact with the ticket 11 at the time of delivery, the contact between the uppermost ticket 11 is reduced. It

Next, at the time of delivering the ticket 11 from the ticket storage portion 21, the rotating shaft 52a is rotationally driven by the electric motor and the delivering roller is delivered.
51 and transport rollers 52, 53 rotate and solenoid
60 is excited, the support frame 54 swings downward, and the feeding roller
51 is pressed against the upper surface of the uppermost ticket 11
By frictional contact with 51, the ticket 11 is sent out through the ticket sending-out section 26.

Since the delivery roller 51 is in contact with the leading end side in the delivery direction of the ticket and the pressing roller 81 is in contact with the rear end side of the delivered ticket 11, for example, the delivery roller 51 is
Even if a deflection force acts on the ticket 11 in the left and right sides orthogonal to the ticket delivery direction with the contact point of the delivery roller 51 as a fulcrum, it is pressed against the ticket 11 by the spring 86 and The pressing roller 81 having a high friction coefficient regulates the swing of the ticket 11. Therefore, the sent-out ticket 11 is
The feeding posture is regulated at two contact positions between the 51 and the pressing roller 81, and the bills are fed in the bill feeding direction with the same fixed posture as when the sheets are stacked in the ticket storage unit 21.

Further, in the state where the pressing roller 81 is in contact with the rear end side of the sent-out ticket 11, the leading end of the ticket 11 is sandwiched between the upper and lower conveying rollers 52, 53, and thus the sent-out ticket 11
Even if the rear end side of 11 is disengaged from the pressing roller 81, the ticket 11 is fed into the transport passage 68 while maintaining a fixed posture.

When the leading edge of the sent-out ticket 11 is nipped between the upper and lower transport rollers 52 and 53 and the transport is started,
The excitation of the solenoid 60 is released, the support frame 54 swings upward due to the bias of the spring 58, and the delivery roller 51 separates from the ticket 11 upward.

Further, the ticket 11 is sent out from the ticket storage section 21,
When the detection roller 76 descends, this is detected by the ticket upper surface position detection unit 71.
Then, the elevating mechanism 41 raises the elevating and lowering support base 31 to raise the uppermost ticket 11 on the elevating and lowering support base 31 to the delivery fixed position, and waits for the next ticket delivery operation.

Further, when all the tickets 11 on the lift support base 31 are sent out and the presser roller 81 is lowered into the detection window hole 32 of the lift support base 31, the lever portion 88 swings downward and the operator 94 is pushed down, the ticket presence / absence detection switch 93 is turned on, and the absence of the ticket 11 is detected.

In the above embodiment, the pressing roller 81 is used for the ticket 11.
Although the skew feeding preventing means and the presence / absence detecting means of the ticket 11 are also used, the pressing roller 81 may be dedicated to the skew feeding preventing means of the ticket 11 and the presence / absence detecting means may be separately provided.

[0043]

According to the present invention, since the pressing roller together with the feeding roller is in pressure contact with the ticket fed from the ticket storage portion, for example, the feeding roller is one-sided against the upper surface of the ticket and Even if a swaying force acts on the ticket on the left and right sides orthogonal to the ticket sending direction with the contact point as a fulcrum, the swaying of the ticket can be regulated by the pressing roller that presses the ticket. Therefore, the sent-out ticket has its sending attitude regulated at the two contact positions of the sending roller and the pressing roller, and is sent in the ticket sending direction with the same fixed attitude as when the stacked sheets are stored in the ticket storage section. Moreover, since the leading edge of the delivery of the ticket is pinched by the transport roller in the state where the pressing roller is in contact with the ticket to be sent out, even if the ticket to be sent out comes off the pressing roller, the ticket remains in the same posture in the ticket sending direction. Sent to.
