JP5568540B2 - Belt tensioning device for medal conveyor belt conveyor - Google Patents

Description

  The present invention relates to a technique for adjusting the tension of a belt in a medal transport belt conveyor for transporting medals used in a medal game facility.

  In gaming machine islands, belt conveyors are generally used as means for supplying medals to medal gaming machines and medal lending machines. The belt conveyor applies moderate tension to the belt and presses it against the rollers to prevent slippage during driving. However, if the belt conveyor is used for a long period of time, the belt will gradually stretch and become slippery. It is necessary to adjust to.

  As a belt tensioning device for automatically adjusting the tension, there is a technique disclosed in Patent Document 1, for example. This technology is characterized by a structure in which the return path of the belt is drawn downward in a loop shape and stretched on a tension roller, and the tension roller is urged by a compression spring in a direction in which tension acts. According to this technique, the compression spring is restored as much as the belt is extended, and a constant tension always acts to maintain the tension.

  By the way, if the compression spring is restored to the state before compression after being used for a long period of time, even if the belt is further stretched thereafter, there is no restoring force, so tension cannot be obtained, and the belt needs to be replaced. However, since the belt tensioning device of the above technology has a structure that occupies the lower space of the belt conveyor, it may not be installed depending on the layout of the gaming machine island due to interference with the medal gaming machine or the medal lending machine.

FIG. 5 is a cross-sectional view taken along line AA of FIG. 4, and FIG. 6 is an explanatory view showing tension of the belt of the embodiment.

  In the figure, 1 is a medal gaming machine, 2 is a medal lending machine, 3 is a medal conveyor belt conveyor, 31 is a conveyor frame, 32 is a belt, 4 is a medal supply device, 5 is a medal recovery belt conveyor, 6 is a belt tensioning device, 61 is a guide frame, 62 is a hook member, 62a is a hook hole, 63 is an auxiliary roller, 64 is a moving frame, 65 is a tension roller, 66 is a tension spring, 7 is a motor, 71 is a mounting base, 72 and 73 are sprockets, 74 is a chain, and A is a gaming machine island.

  As shown in FIG. 1, the gaming machine island A of the present embodiment includes a medal gaming machine 1 and a medal lending machine 2 that are adjacent to each other with a gap, a medal transport belt conveyor 3 that transports medals to these, and a medal transport. A medal supply device 4 that supplies medals to the belt conveyor 3 and a medal collection belt conveyor 5 that recovers medals used in the medal gaming machine 1 to the medal supply device 4 are configured. The belt tensioning device 6 is attached to a gap position between the medal game machine 1 and the medal lending machine 2 of the medal transport belt conveyor 3 and a midway position of the medal recovery belt conveyor 5.

  As shown in FIGS. 2 to 5, the belt tensioning device 6 is attached to the left and right side surfaces of the conveyor frame 31 so that the longitudinal guide frames 61 extend downward at a predetermined interval in the front and rear directions in the transport direction. A hook member 62 having hook holes 62a for hooking a tension spring 66 at the four corners is attached to the lower part of 61, and an auxiliary roller 63 is pivotally supported at the lower position of the return path of the belt 32 on each of the front and rear guide frames 61. doing.

  A moving frame 64 is disposed vertically between the front and rear guide frames 61, and the tension roller 65 is rotatably supported by the moving frame 64, and the belt 32 is moved in the middle of the return path between the front and rear auxiliary rollers 63. The tension roller 65 is pulled out downward and stretched. Another hook member 62 having the same structure as described above is attached to the upper portion of the moving frame 64, and the upper and lower ends of the tension spring 66 are hooked and connected to the hook holes 62a of the upper and lower hook members 62.

  The motor 7 is attached to the upper hooking member 62 via the mounting base 71, and a chain 74 is stretched between a sprocket 72 provided on the output shaft of the motor 7 and a sprocket 73 provided on the shaft of the tension roller 65. Yes.

  With this structure, as shown in FIG. 6A, the moving frame 64 is slightly lowered along the guide frame 61 due to its own weight, the tension roller 65, the weight of the motor 7, and the tension force of the tension spring 66. The return path of the belt 32 is pushed down to be tense. Thereafter, when the belt 32 is gradually extended during use, the moving frame 64 is naturally lowered by that amount, and the belt 32 is continuously tensioned with a constant tension. Since the motor 7 is attached to the moving frame 64, even if the moving frame 64 moves up and down, the distance between the tension roller 65 and the motor 7 does not change, and transmission of driving force is not affected.

  When the belt 32 further extends and the moving frame 64 continues to fall, as shown in FIG. 6B, either the upper hooking member 62 contacts the conveyor frame 31 or the moving frame 64 lowers the hooking member 62. The tension roller 65 cannot press down the belt 32. In this case, since the belt 32 cannot be tensioned even if it extends beyond this, the belt 32 needs to be replaced.

  When the moving frame 64 is lifted, the position of the tension roller 65 moves upward and the belt 32 is greatly loosened. The loose belt 32 is pulled up and replaced with a new belt 32, or the belt 32 is cut out by the stretched length and both ends are connected. After the replacement, as shown in FIG. 6A, the moving frame 64 is slightly lowered along the guide frame 61 by itself, the tension roller 65, the weight of the motor 7, and the tension force of the tension spring 66, and the tension roller 65 is moved. The belt 32 is pushed down to be tense.

  Even when tension is applied, when the belt 32 is torn due to some trouble and is replaced with a new belt 32 or the broken portion is reconnected, the operation can be performed in the same manner as described above. is there. In this embodiment, the belt tensioning device 6 attached to the medal transport belt conveyor 3 has been described. However, the belt tensioning device 6 attached to the medal recovery belt conveyor 5 has the same configuration and operational effects.
