〔Example〕

Next, preferred embodiments according to the present invention will be described in detail with reference to the drawings.

The embodiment shows a ticket processor for reading a paper ticket such as a ticket, and the belt-type transport device according to the present invention is incorporated in the ticket processor.

First, the structure of the belt-type transfer device is shown in FIGS.
This will be described with reference to the drawings.

The transport device 1 includes a main body frame 11. Body frame
Numeral 11 includes a left frame 12 and a right frame 13 which are long in the front-rear direction, and a plurality of support bars 14 are erected between the frames 12 and 13 for connection. Further, a front panel 15 is attached to a front portion of the main body frame 11, and an entrance 16 for a ticket is attached to the panel 15.

On the other hand, between the frames 12 and 13, the upper belt feed mechanism 2 is provided on the upper side, and the lower belt feed mechanism 21 is provided on the lower side.

The lower belt feed mechanism 21 includes an idle front roller 22 provided near the front end of the main body frame 11 and a driven rear roller 23 provided near the rear end, and has a predetermined elasticity between the rollers 22 and 23. A rubber endless belt 24 is stretched over it. The endless belt 24 may be a flat belt similar to a conventional one. Also,
At predetermined intermediate positions between the rollers 22 and 23, idle-type guide rollers 25, 26, and 27 are provided to abut against the lower surface of the endless belt 24 located on the upper side, and the lower surface of the endless belt 24 located on the lower side is further provided. There is provided a tension roller 28 that pushes upward to apply a predetermined tension. The rollers 22, 25, 26, 27 and 28 except the rear roller 23 are supported by shafts 29 provided between the frames 12 and 13. Also, the rear roller 23
Is fixed to the shaft 30, is manually fed by a knob 31 attached to one end of the shaft 30, and is rotated by a driving unit 32 connected to the other end of the shaft 30. The driving unit 32 includes a driven pulley 33 fixed to the shaft 30, a motor 34 mounted on the left frame 12, a driving pulley 35 mounted on the shaft of the motor 34, and a transmission belt 36 bridged between each pulley 33 and 35. .

On the other hand, the upper belt feed mechanism 2 includes an idling type front roller 7 disposed above the front roller 22 and an idling type intermediate roller 4 disposed substantially at the center of the main body frame 11 in the front-rear direction.
They are rotatably supported by shafts 51 and 52, respectively. In this case, the distance between the front roller 7 and the intermediate roller 4 is set to be shorter than the length of the conveyed object, that is, the ticket S.

The front end of the movable arm 6 is rotatably hingedly connected to the shaft 52 supporting the intermediate roller 4. The movable arm 6 includes a left arm 53 and a right arm 54, and each arm 53 and 54
Are connected by a plurality of support bars 55. At the rear end of the movable arm 6, the idling rear roller 5 is rotatably supported by a shaft 56. Then, the front roller 7 and the rear roller 5
An elastic endless belt 3 made of rubber is stretched between them. An idle type guide roller 57 is provided between the front roller 7 and the intermediate roller 4.
Is rotatably supported by the shaft 58 and is brought into contact with the upper surface of the endless belt 3 located on the lower side. On the other hand, in the vicinity of the front end of the movable arm 6, an idle tension roller 59, which is in pressure contact with the lower surface of the endless belt 3 located above (opposite the intermediate roller), is rotatably supported by a shaft 60, and the movable arm 6 is supported. When the endless belt 3 is set to the use position, the intermediate portion of the endless belt 3 located on the upper side is slightly bulged upward.

The movable arm 6 is vertically displaced about the shaft 52 in a vertical direction.
It is regulated by the position of the support bar 14 provided on the side, and this support bar 14 also serves as a stopper for locking the movable arm 6. The lower limit is regulated by a predetermined lock mechanism. The lock mechanism locks the movable arm 6 toward the main body frame 11 when the movable arm 6 is moved downward and is set at a fixed position, and is simultaneously positioned at this time.

Each roller described above is provided with a pair of left and right roller bodies separated by a predetermined width, and each endless belt is also provided with a pair of left and right corresponding to this.

Next, the function of such a belt-type transport device 1 will be described.

First, the operation of the motor 34 in the drive unit 32 causes the endless belt 24 to circulate, and the other endless belt 3 circulates accordingly. Therefore, ticket S to the entrance 16
Is transported to a fixed position behind by the endless belts 3 and 24, and a predetermined process is performed. When the processing is completed, the motor 34 is rotated in the reverse direction, and the ticket S is transported forward. Thereby, the ticket S can be taken out from the entrance 16.

By the way, when the inserted ticket S is jammed in the belt surface during the conveyance due to the tearing, breaking or deformation of the ticket S, so-called jam processing is required. In this case, when the lock in the predetermined lock mechanism is released and the movable arm 6 is lifted lightly, the movable arm 6 is moved to a position beyond the equilibrium point P determined by the position of the tension roller 59 as shown in FIG. As a result, the endless belt 3 is raised by the elasticity of the endless belt 3 by itself, and the rear half of the upper belt feed mechanism 2 can be opened with respect to the lower belt feed mechanism 21. When the movable arm 6 is returned downward and set to the use position, the rear end of the movable arm 6 is urged downward by the elastic action of the endless belt 3 from the position passing the equilibrium point P, and 3 and 24 abut each other with an appropriate pressing force. Although the endless belt 3 becomes a triangular shape in a side view due to the upward movement of the movable arm 6, the endless belt 3 does not loosen if it is stretched about 10% from the natural state and stretched over. In addition, the movable arm 6
When a predetermined opening angle is obtained, the movable arm 6 is moved more than when the entire upper belt feed mechanism 2 is lifted as in the related art.
The height of the upper end of the is only half. Further, as shown in FIG. 6, since the outer end distance L1 between the front roller 7 and the intermediate roller 4 is set to be shorter than the length L2 of the ticket S, the ticket S is always separated from the front roller 7 even if the ticket S is jammed. Is also exposed behind the front entrance 16 or the intermediate roller 4.

It should be further noted that the space between the front roller 7 and the intermediate roller 4 is not affected at all by the vertical movement of the movable arm 6. For this reason, the guide rollers 25, 26, 27, and 57 described above are centrally arranged during this period, so that the weight of the movable arm 6 can be reduced, and the reading head 42 and the position sensors 43 and 44 that require positional accuracy are required. , 45 and other functional parts. In particular, position sensor 45 (same for 43 and 44)
As shown in FIG. 7, an integrated optical sensor in which a light emitting portion 46 and a light receiving portion 47 arranged above and below a ticket S are provided on a U-shaped support member 48 can be used, and the accuracy of position detection can be improved. Can contribute.

FIG. 5 shows a case where the belt-type transport device 1 according to the present invention is incorporated in an actual ticket processing machine M. As shown in the figure,
Although the transfer device 1 is accommodated in the outer case 61, there is an advantage that the height of the movable arm 6 projecting upward during the jam clearance is extremely small, and the area of the opening / closing cover 62 attached to the side surface is small. The endless belt 24 can be manually fed by turning the knob 31 by opening the openable cover 62.

Although the embodiments have been described in detail, the present invention is not limited to such embodiments. For example, the ticket processing machine has been described as an example, but the present invention can be applied to a belt-type transport device that transports any transported object such as a card. In addition, the position, quantity, drive method, and the like of each roller can be arbitrarily implemented. Furthermore, the case where the sheet is conveyed in the horizontal direction is shown,
The same applies to the case where the sheet is conveyed in the vertical direction or the like, and the belt feeding mechanism is shown as being open on the rear side, but may be of the type opening on the front side. In addition, details, configurations, shapes, arrangements, materials, quantities, and the like can be arbitrarily changed without departing from the gist of the present invention.

〔The invention's effect〕

Thus, the belt-type transport device according to the present invention uses an elastic endless belt for at least one belt feed mechanism,
An intermediate roller fixed at an intermediate position is provided, and a rear roller (front roller) is provided at a distal end of a movable arm rotatably provided on a side on which the intermediate roller is provided. Since the distance between the two rollers is set shorter than the length of the transferred object, the following effects are obtained.

When opening one of the belt feed mechanisms, it is sufficient to open only a part of the rear portion by the movable arm, so that the dead space associated with the upward movement of the movable arm can be reduced.

Since the number of components attached to the movable arm can be reduced and a significant reduction in weight can be achieved, the opening and closing of the belt feeding function can be performed smoothly and easily, especially in the case of a large-sized device.

The movable mechanism itself such as the hinge mechanism can be reduced in size and simplified, and the peripheral structure such as the opening and closing cover of the outer case can be reduced in size and simplified.

Since the distance between the roller and the intermediate roller is set shorter than the length of the transferred object, the transferred object is exposed to the outside of the belt surface even when the transferred object is clogged or the like, and can be easily taken out.

Functional parts requiring positional accuracy, such as rollers, read heads, and position sensors, can be attached to the non-opening / closing part of the belt feed mechanism.
It can contribute to higher accuracy.
