DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving pulley and a driven pulley which are spaced apart from each other, and an endless belt is wound between the pulley and the endless belt. The present invention relates to a transport device that moves in a transport path as it moves and a belt tension adjusting device for an endless belt.

[0002]

2. Description of the Related Art In a conventional conveying apparatus, an endless belt is stretched over a driving pulley and a driven pulley which are spaced apart from each other, the endless belt is moved with the rotation of the driving pulley, and paper sheets are transferred on a conveying path. The endless belt is sandwiched between the holding pulley and the endless belt, and is moved in the transport path with the movement of the endless belt. The endless belt used in such a transport device gradually grows and sags as it is used. The loose endless belt causes unevenness in the transport speed of the paper sheets, causing skew, and as a result, transport jam occurs. Further, the endless belt slack is or rubbing with Iroi filtrate <br/> parts, or worn belt, out flour, interfere with the transport. To prevent this, hang a tension adjustment pulley on a part of the endless belt and use a tool to
The tension adjusting pulley is mounted with its fulcrum changed in position to return the tension to the endless belt.

[0003]

However, in such a conventional technique, the position of the tension adjusting pulley must be changed using a tool in order to adjust the tension of the endless belt, so that the endless belt extends. Each time, it takes time and effort to adjust it, and there is a problem that it is not troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems of the prior art, and does not require the use of tools and makes it possible to easily adjust the tension of an endless belt. It is an object to provide a tension adjusting device.

[0005]

[0007]

When adjusting the length of the endless belt, hold the grip of the handle, hold one end of the link as it is, and connect the other end of the handle to the support of the support. The endless belt is moved to a position further away from the pulley at one end, and is hung on a support at that position.

Next, using the other end of the handle portion as a fulcrum, the grip portion of the handle portion is moved away from the pulley at one end of the endless belt, and the tension adjusting pulley at one end of the link portion is pulled in the same direction. Set the spindle of the tension adjustment pulley
The endless belt is moved to a position further away from the pulley at one end, and is hung on a support at that position.

The endless belt is constrained by a regulating pulley along the transport path, and thus the tension of the endless belt can be adjusted.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show one embodiment of the present invention.

As shown in FIG. 3, a plurality of pachinko game machines 11,... Are juxtaposed on a game machine island 10 arranged in a game arcade, and a ball rental machine is provided between the pachinko game machines 11. 12 are provided. The ball lending machine 12 lends pachinko balls to a player in exchange for bills.

Inside the game machine island 10, along with the pachinko game machines 11,... And the ball rental machines 12,.
3 are provided. The transport device 13 transports the banknotes taken in by the ball lending machine 12 to a stacker (not shown) of a money changer arranged on the island end.

The transport device 13 has a drive pulley 14 and a driven pulley 15 disposed at both ends of the game machine island 10 at a distance from each other, and an endless belt 16 is wound around the drive pulley 14 and the driven pulley 15. The endless belt 16 is moved between the pulley 18 and the endless belt 16 on the transport path 17, and the paper is moved in the transport path 17 as the endless belt 16 moves.

As shown in FIG. 1, the belt tension adjusting device 20 for the endless belt 16 used in the transport device 13 includes a support portion 30, a tension adjusting pulley 40, a regulating pulley 50, a link portion, 60 and a handle 70.

The support portion 30 is fixed to one end of the gaming machine island 10 and supports the driven pulley 15. The tension adjusting pulley 40 has a support shaft 41 and is stretched under the driven pulley 15 near one end of the endless belt 16. The restriction pulley 50 has a support shaft 51, and the support shaft 51 is rotatably provided at an end 31 of the support portion 30 protruding inward from the gaming machine island 10.

The mounting position of the restriction pulley 50 at one end near the endless belt 16, and a near position <br/> location of the terminal end of the conveying path 17, restricting the pulley 50, the tension adjustment pulley and the endless belt 16 40, the endless belt 16
Is restrained so as to be along the transport path 17.

One end 61 of the link portion 60 is rotatably attached to the support shaft 41 of the tension adjusting pulley 40, and the other end 62 is slightly bent. Handle part 70
A grip 71 is formed at one end, and a link 6 is provided between the grip 71 at one end and the other end 72 by a rotating shaft 73.
0 is rotatably attached to the other end 62. Handle part 7
No. 0 has a rotating shaft 73 attached to a slightly bent side of the link portion 60, and a portion between the grip portion 71 and the rotating shaft 73 is bent toward the link portion 60.

The support portion 30 has a support shaft of the tension adjusting pulley 40 at a plurality of positions which are stepwise separated from the driven pulley 15 and the regulating pulley 50 at one end of the endless belt 16 in a direction perpendicular to the conveying path 17. Bearings 32a, 32b, 32c, 32d for 41 and the other end 72 of the handle 70
have. Bearings 32a, 32b, 32c, 32d
Is formed in the support portion 30 by a groove extending along the vertical direction thereof and obliquely cut upward.

Next, the operation will be described. In FIG. 1, when the endless belt 16 is extended, in order to give tension,
When adjusting the length, the grip part 71 of the handle part 70 is gripped and the grip part 71 is lifted upward. Thus, one end of the link portion 60 is kept at the same position (the position of the support portion 32a in FIG. 1), and the other end 72 of the handle portion 70 is
Is moved from the position of the support portion 32c to a lower position further away from the driven pulley 15 among the plurality of support portions 32a, 32b, 32c, 32d of the support portion 30, and is hung on the support portion 32d at that position. .

Next, as shown in FIG.
Of the handle portion 70 with the other end 72 of the
Is moved downward away from the driven pulley 15, and the tension adjusting pulley 40 at one end 61 of the link portion 60 is pulled in the same direction. The support shaft 41 of the tension adjusting pulley 40 is moved to a lower position further away from the driven pulley 15,
Hang it on the support 32b at that position.

The endless belt 16 is constrained by the regulating pulley 50 along the transport path 17, and thus the tension of the endless belt 16 can be adjusted. Further, when the endless belt 16 is extended, the other end 72 of the handle 70 and the support shaft 41 of the tension adjustment pulley 40 may be hung on a lower support in a similar procedure.

The paper sheets conveyed by the endless belt 16 may be not only bills but also cards and the like.

[0023]

According to the conveying device and the belt tension adjusting device of the present invention, the grip portion of the handle portion is gripped, and the tension adjusting pulley at one end of the link portion is pulled with the other end of the handle portion as a fulcrum, thereby adjusting the tension. Since the tension of the endless belt can be adjusted by hanging the support shaft of the pulley on the bearing at that position, it is not necessary to use a tool, and the tension of the endless belt can be easily adjusted.
