[0017]
Of the above-described configuration, since the end portion of the key groove 57 on which the cloth belt mounting shaft 58 can be mounted and the mounting long groove 54 on which the winding roller 56 can be mounted is opened, the cloth belt mounting shaft 58 is formed. In addition, the mounting operation of the winding roller 56 can be performed very easily. In addition, since the auxiliary roller 55, the winding roller 56, and the weight roller 60 are configured with relatively heavy weights, the shaft does not swing and rotate during each rotation operation. The interval between the lower end of the attachment long groove 54 and the key groove 57 is formed to be slightly larger than the radius of the cloth belt roll 90a before use, and the depth of the attachment long groove 54 is also the cloth belt after use. It is formed so as to have an interval slightly larger than the radius of the roll 90b. The operation of the cloth belt mounting unit 50 will be described in detail later.
[0018]
Next, the configuration of the chucking unit 62 will be described with reference to FIGS. 9 to 13. 9 is a perspective view of the fabric belt mounting unit 50 and the chucking unit 62 as described above, FIG. 10 is a perspective view of the chucking unit 62, and FIG. 11 is a chucking unit mainly showing an opening / closing mechanism. FIG. 12 is a side view showing a chucking state, and FIG. 13 is a side view showing a non-chucking state.
[0019]
In the drawing, the chucking unit 62 is provided on the lower mounting frame plate 53 as described above. That is, the attachment pieces 63 are erected on both sides of the lower portion of the lower attachment frame plate 53, and one chucking rubber 64 is adhered between the attachment pieces 63. In addition, an opening / closing box 65 as an opening / closing lid is attached to one side of the attachment piece 63 through a hinge 76 so as to be freely opened and closed, and the other part of the attachment piece 63 constitutes a part of a locking mechanism of the opening / closing box 65. Locking pieces 77a and 77b are connected and formed.
[0020]
A restriction bar 66 and a support bar 67 are passed in the upper front of the open / close box 65 in the vertical direction, and a swing plate 68 is pivotally supported on the support bar 67 over almost the entire length thereof. ing. Another chucking rubber 69 corresponding to the chucking rubber 64 is attached to the lower front surface of the swing plate 68. A rotating shaft 70 is rotatably supported behind the swing plate 68, and a pair of eccentric cams 71 are fixed to the rotating shaft 70. Further, at one end side of the rotating shaft 70, it is connected to a motor 75 as an electric drive source fixed to one side outside of the opening / closing box 65 by a gear mechanism (not shown) so that the motor 75 rotates forward and reverse. It has become. In order to control the rotation of the motor 75, a switching cam 72 is fixed to one side portion of the rotating shaft 70, and is operated by operating protrusions 72a and 72b protruding from the switching cam 72 at a predetermined interval. A pair of switches 74 a and 74 b are attached to the back side of the front face of the open / close box 65 via a switch attachment plate 73. The bearings on the support side of the regulation bar 66, the support bar 67, and the rotating shaft 70 are supported by a bearing plate 85 fixed inside the support side of the opening / closing box 65. ing. The electric drive source for moving the eccentric cam 71 may not be a motor but may be another drive source such as a solenoid.
[0021]
Further, as described above, the opening / closing box 65 is freely opened and closed by the hinge 76. However, as shown in FIG. 11, the opening-side mounting piece 63 has locking pieces 77a, 77b as a locking structure at the time of closing. A key piece 79 having claw portions 80a and 80b engaged with the locking pieces 77a and 77b is slidably provided along the guide piece 78 on the opening / closing box 65 side. A spring 82 that constantly biases downward is locked to the key piece 79, and an operation lever 81 that protrudes outside the side wall of the opening / closing box 65 is provided. Therefore, when opening the opening / closing box 65, the operating lever 81 is pressed upward against the urging force of the spring 82 to move the key piece 79 upward, and the claw portions 80a, 80b and the locking pieces 77a, 77b are moved. This can be done easily by releasing the engagement. When the open / close box 65 is opened, the cloth belt 90 can be easily passed between the chucking rubbers 64 and 69 facing each other. After passing the cloth belt 90, the open / close box 65 is closed and pressed. The claw portions 80a and 80b of the key piece 79 are automatically engaged with the locking pieces 77a and 77b.
[0022]
When the open / close box 65 is locked as described above, the eccentric cam 71 is pressed against the back surface of the swinging plate 68 as shown in FIG. The belt 90 is in a chucked state so as not to move. When a rotation command is derived to the motor 75 from such a state, the rotation shaft 70 rotates and the operation projection 72a turns on the switch 74a to stop the rotation. When the rotation is stopped, the eccentric cam 71 is not in a state of pressing the back surface of the swinging plate 68, so that the lower end of the swinging plate 68 swings backward and between the chucking rubbers 64, 69 facing each other. The cloth belt 90 is not chucked due to a gap in the non-chucking state. At this time, as shown in FIG. 13, the upper end of the swing plate 68 abuts against the regulating bar 66, so that the swing plate 68 does not swing more than necessary. When a predetermined time (a time slightly shorter than the rotation time of the motor 30 of the tension unit 20) elapses after the non-chucking state is reached, the motor 75 rotates in the reverse direction and rotates. 70 also rotates in the reverse direction until the operating projection 72b turns on the switch 74b. When the rotation is stopped, the eccentric cam 71 presses the back surface of the swing plate 68, so that the lower end of the swing plate 68 swings forward, and the facing chucking rubbers 64, 69 are cloth. The belt 90 is in a chucked state.
[0023]
Next, operations of the tension unit 20, the fabric belt mounting unit 50, and the chucking unit 62 having the above-described configuration will be described mainly with reference to FIGS. First, the operation of attaching the cloth belt 90 to the ball polishing and lifting device 10 will be described. The cloth belt of the new pre-use cloth belt roll 90a with the cover lid 32 of the tension unit 20 and the opening / closing box 65 of the chucking unit 62 opened. After dropping the mounting shaft 58 into the keyway 57 of the fabric belt mounting unit 50, the front end of the fabric belt 90 is dropped forward of the chucking rubber 64 of the chucking unit 62 that is opened from the upper part of the auxiliary roller 55. Thereafter, the cloth belt 90 is passed from the lower part to the upper part on the front surface of the cover plate 17 in the opened state, and the cloth belt 90 is hung in front of the driving roller 25 in the opened state of the tension unit 20 and wound under the weight roller 60. The take-up roller 56 is wound around in the clockwise direction in FIG.
[0024]
After the attachment as described above is completed, first, the open / close box 65 of the chucking unit 62 is closed, and the fabric belt 90 is chucked by the pair of chucking rubbers 64 and 69, and then the fabric belt below the tension unit 20 is placed. While pulling 90 strongly, the cover lid 32 of the tension unit 20 is closed and the locking handle 34 is rotated to lock the locking piece 35 and the locking hole 36. In this state, the driving roller 25 and the pressure rollers 38a and 38b are in pressure contact with the cloth belt 90. After that, the extra fabric belt 90 drawn out is wound around the take-up roller 56 and taken up. At this time, it is desirable that the tension is always applied to the cloth belt 90 wound around the winding roller 56 by winding the weight roller 60 until it slightly floats. After the installation of the fabric belt 90 is completed as described above, the cover plate 17 is closed and the fastening lever device 18 is engaged, so that the fabric belt 90 and the conveyor belt 14 face each other.
[0025]
When the mounting of the new fabric belt 90 is completed as described above, the ball polishing and lifting device 10 can be immediately operated to perform the ball polishing operation. And, for example, in order to wind up the fabric belt 90 after the end of the day's business, the open / close door of the ball polishing and lifting device housing 3 of the pachinko island 1 is opened and the cover cover of the tension unit 20 is opened. The start switch 39 provided at 32 is turned on. When the ON signal of the start switch 39 is derived, the control circuit formed on the control board 4 performs control as described below.
[0026]
First, the motor 75 of the chucking unit 62 is rotationally driven to release the chucking state of the chucking rubbers 64 and 69 to be in a non-chucking state, and then a rotation command is given to the motor 30 of the tension unit 20. By driving the motor 30 of the tension unit 20, the entire fabric belt 90 is pulled by the drive roller 25 and the pressure rollers 38a and 38b. When the fabric belt 90 is pulled, the auxiliary roller 55 of the fabric belt mounting unit 50 rotates, and the winding roller 56 in contact therewith also rotates. Therefore, the fabric belt 90 pulled by the tension unit 20 is rotated by the winding roller. 56. At this time, since the fabric belt 90 wound around the winding roller 56 is wound in a state in which it is always tensioned by the weight roller 60, there is no turbulence. When a predetermined time (time when the new cloth belt 90 is located on the front surface of the cover plate 17) has elapsed since the start of such winding operation, first, the motor 75 of the chucking unit 62 is reversed. It rotates to become a chucking state, and then the driving of the motor 30 of the tension unit 20 is stopped after a slight time difference. Thereby, the winding operation of the fabric belt 90 is completed, and such an operation is performed at the end of business every day. The cloth belt 90 has a length of about one week if the above-described operation is performed every day.
[0027]
As described above, the ball polishing and lifting device 10 according to the present embodiment is configured so that the auxiliary roller 55 rotates when the cloth belt 90 is pulled and moved during the winding operation of the used cloth belt 90b on the winding roller 56. Since the winding roller 56 is rotated by being driven, the structure is very simple, and the pulling operation and the winding operation of the cloth belt 90 are performed by the driving force of one motor 30. The relationship between the tension length and the winding length of the fabric belt 90 per unit time is always constant, and the web is wound in a state in which it is always tensioned by the weight roller 60. Can be wound.
[0028]
In the above-described embodiment, the driving time of the motor 30 of the tension unit 20 has been described as the time for the use surface of the cloth belt 90 to be replaced with the unused surface. However, on the rule of thumb, the ball inlet 15 portion is extremely dirty. Therefore, even if only that portion is moved upward and used thereafter, sufficient ball polishing ability can be exhibited, so it may be set to half or one third of the above time. Further, although the chucking rubbers 64 and 69 are exemplified as the chucking members of the chucking unit 62, they may be made of synthetic resin or other materials as long as they exhibit a high frictional force. In the above embodiment, the cloth belt mounting unit 50 and the chucking unit 62 are integrated with the upper mounting frame 51 and the lower mounting frame plate 53 and mounted with the mounting brackets 83 and 84. It may be mounted separately, or the tension unit 20 may be integrated so that the three units can be mounted integrally.
[0029]
Further, in the above-described embodiment, the start switch 39 is operated to automatically perform the winding operation of the fabric belt 90 every time the business day is finished. A sensor for detecting the above may be provided, and the above-described operation may be performed when the sensor is turned on. At this time, the inflow of the balls into the ball inlet 15 of the ball polishing and lifting device 10 is stopped, and the winding operation of the cloth belt 90 is performed in a state where the pachinko balls are completely removed in the lifting device 10. Is desirable. In addition, a sensor that detects that the remaining amount of the unused cloth belt 90 is low may be provided, and a notification may be given (through visual or auditory sense) so that the clerk of the game hall can know when the sensor is activated. Further, when the old and new cloth belts are exchanged, the new and old cloth belts are easily attached to the ball polishing and lifting device 10 by being drawn by the pulling unit 20 in a state where the new and old cloth belts are connected by a special metal fitting. be able to. In addition, the control board 4 is not provided for each pachinko island platform 1, but is provided in one place and operated at that place to perform the winding work of the cloth belts of all the ball polishing and lifting devices 10 in the game hall. You may make it do.
[0030]
【The invention's effect】
As is apparent from the above description, in the invention according to claim 1, since the relationship between the tensile length of the fabric belt per unit time and the winding length is always constant, there is no turbulence, The cloth belt can be wound up to the end, and the cloth belt can be brought into a pressure contact state between the driving roller and the pressure roller very easily .
