FIG. 7 is a side view of the upper portion of the ball polishing and lifting device 20, and FIG. 8 is a cross-sectional view taken along line AA of FIG. However, in each figure, the cloth belt automatic winding mechanism attached to the back surface of the guide rail cover 33 is not shown.
[0012]
In the figure, the ball polishing and lifting device 20 includes a lower roller 23 and an upper roller 24 in which a lifting cylinder main body 22 is erected vertically on an upper portion of a support base 21 and the periphery of the lifting cylinder main body 22 is supported at the lower portion. A leather conveyor belt 25 that runs between the two belts circulates. The circumferential drive of the conveyor belt 25 is performed by connecting a motor 27 and a lower roller 23 mounted and fixed on a motor mounting base 26 fixed to the support base 21 by a V-belt 28. A plurality of tension rollers 29 are attached to the feeding cylinder body 22 above the lower roller 23 in order to apply tension to the conveyor belt 25. In addition, the lower part of the lifting cylinder body 22 is connected to an introduction rod 30 into which pachinko balls before the ball polishing flows and are arranged in a plurality of rows, and the upper part of the lifting cylinder body 22 is connected to the pachinko machine after the ball polishing. An upper bent rod 31 and a discharge rod 32 from which balls are discharged are formed.
[0013]
Therefore, the pachinko balls that have flowed in from the introduction basket 30 are lifted by the conveyor belt 25 and discharged from the discharge basket 32, and adhere to the pachinko balls by the frictional force with the cloth belt 37 described later in the process of being lifted. The cleaned dirt is wiped off, and the pachinko balls made clean are discharged from the discharge basket 32. As shown in FIG. 4, an internal guide roller 42 is rotatably supported at substantially equal intervals in the inside of the feed cylinder main body 22, and the front end portion of the internal guide roller 42 (facing the cloth belt 37 is faced). The side) faces a rectangular standing window (not shown) formed in the feeding cylinder main body 22 and comes into contact with the conveying belt 25, thereby guiding the rotating operation of the conveying belt 25.
[0014]
On the other hand, a guide rail cover 33 is detachably attached to the back side of the above-described lifting cylinder body 22. The guide rail cover 33 is removed when the conveying belt 25 or the cloth belt 37 is attached to the ball polishing and feeding device 20, and the cloth belt 37 itself is attached so as to go around the guide rail cover 33. The When the transport belt 25 and the cloth belt 37 are attached, the guide rail cover 33 is maintained in a state where the guide rail cover 33 faces the feed cylinder main body 22 by the stopper 43. However, a gap is formed between the lifting cylinder main body 22 and the guide rail cover 33, and the dimension of the gap can be set by adjusting the fixing position of the stopper 30. It is possible to change the pressure applied to the pachinko balls being pumped according to the set value.
[0015]
Incidentally, as shown in FIG. 4, the guide rail cover 33 described above has a plurality of rows of semicircular ball paths 35 in which the back surface thereof is pressed by a number of springs 36 and pachinko balls are fitted on the front surface thereof. A ball passage forming member 34 to be formed is stored and installed, and a use cloth roll mounting portion 38 for mounting a roll cloth belt before use on its back surface and a roll for winding a used cloth belt in a roll shape. A finished cloth belt mounting portion 39 is provided, and a roller 40 for guiding the fabric belt is provided at the upper rear portion thereof.
[0016]
The cloth belt 37 attached to the pre-use cloth belt attaching portion 38 is then passed from the lower end of the guide rail cover 33 through the front surface of the ball path forming member 34 to the roller 40, and then the used cloth belt attached. It is wound around the part 39. Then, with the cloth belt 37 attached, the guide rail cover 33 is attached to the lifting cylinder main body 22 with the stopper 43, so that the cloth belt 37 and the conveyor belt 25 face each other, and the conveyor belt 25 circulates. By operating the pachinko ball, the pachinko ball is raised while being fitted into the ball passage 35 of the ball passage forming member 34 and pressed by the spring 36 to remove the dirt from the cloth belt 37. At the end of the business, with the chucking device provided in the pre-use cloth belt mounting portion 38 loosened so that the cloth belt 37 can move, the cloth belt 37 on the upper back is pulled to guide the unused surface to the guide rail. The cover 33 is positioned on the front surface side, and the used cloth belt 37 is wound around the used cloth belt mounting portion 39 to tighten the chucking device. This completes the preparation for the next day of polishing. The winding operation of the fabric belt 37 can be performed with the guide rail cover 33 removed from the lifting cylinder main body 22 or with the guide rail cover 33 attached. When exchanging, it is necessary to remove the guide rail cover 33 from the lifting cylinder body 22.
[0017]
Further, the lifting cylinder main body 22 and the guide rail cover 33 of the above-described ball polishing and lifting device 20 are attached by a stopper 43, and the stopper 43 is attached to the guide rail cover 33 as shown in FIG. The engaging projections 41 projecting from the side are supported and engaged, and stoppers 43 provided at a plurality of locations on both side surfaces of the lifting cylinder main body 22 are connected by connecting rods 44.

On the contrary, by removing the catching state of the catch clip 45, the guide rail cover 33 can be attached to the feeding cylinder body 22 with the stopper 43 and the engaging projection 41 engaged.
[0018]
In the ball polishing and lifting device 20 configured as described above, as shown in FIGS. 6 to 8, the individual ball passages 35 a to 35 a of the ball passage 35 are arranged below the bent portion of the upper bending rod 31 on the upper portion. Sensors 50a to 50g corresponding to 35g are provided. In the case of the illustration, the position where the sensors 50a to 50g are provided is the starting end of the upper bending rod 31 that is not clearly defined by the ball passages 35a to 35g. However, at that position, each ball row is still in a line shape. Since it is being transported, it is possible to accurately detect the passage of balls in each row. The sensors 50 a to 50 g are connected to the control circuit 10.
[0019]
The operation of the ball polishing and lifting device 20 that is driven and controlled by the control circuit 10 will be described. First, the operation at the start of business will be described as the first operation. When the store clerk operates the operation switch 9 as the business start operation means, the operation signal is input to the control circuit 10. Then, a signal for starting the driving of the motor 27 of the conveyor belt 25 is derived from the control circuit 10 and the conveyor belt 25 is turned. When a predetermined time (for example, 20 seconds) elapses after the drive of the motor 27 is started, a drive signal is derived from the control circuit 10 to the motor 8 of the stopper device 7 so that the stopper device 7 opens the introduction passage 6 and stores it. The balls stored in the tank 4 are supplied to the ball polishing and lifting device 20 to perform the ball polishing and lifting operation. As described above, by operating the operation switch 9 at the start of business, the transport belt 25 is first driven, and then the balls are supplied to the transport belt 25. Therefore, the transport belt 25 at the time of business start. Can be performed very smoothly, and as a result, the ball lifting operation can be performed reliably and smoothly.
[0020]
As the second operation, the operation at the end of business hours will be described. When the store clerk operates the operation switch 9 as the business end operation means, the operation signal is input to the control circuit 10. Then, a drive signal is derived from the control circuit 10 to the motor 8 of the stopper device 7, and the stopper device 7 closes the introduction passage 6. For this reason, the balls stored in the storage tank 4 are not supplied to the ball polishing and lifting device 20, and the passage of the balls is not detected by the sensor 50 after a certain period of time has elapsed. When a ball passage detection signal from the sensor 50 is not derived and a predetermined time (for example, 20 seconds) elapses, a stop signal is derived from the control circuit 10 to the motor 27 of the conveyor belt 25, and the driving of the conveyor belt 25 is stopped. Then, the ball lifting operation is completed. In this way, by operating the operation switch 9 at the end of business, first, the supply of the balls to the ball polishing and lifting device 20 is stopped, and the sensor 50 is transported after a predetermined time after detecting the passage of the balls. Since the conveying operation by the belt 25 is stopped, no balls remain in the ball polishing and lifting device 20. For this reason, until the next day's start of business, as compared with the conventional case where the balls are left in the ball polishing / lifting device 20, the conveying belt 25 and the cloth belt 37 are adversely affected. There is nothing.
[0021]
As a third operation, an operation at the time of driving the ball polishing and lifting device 20 during business operation or in a test mode will be described. When the ball lifting operation by the conveyor belt 25 is performed smoothly, the sensor 50 Thus, balls passing through the ball passage 35 are detected every moment. In this case, the total number of detection signals per unit time (for example, 1 minute) is displayed on the numerical display 11 a of the display device 11. The unit time measurement start signal and the measurement end signal are automatically derived in the control circuit 10, and the count value calculated based on the signal is displayed on the numerical value display 11a for a predetermined time. The measured count value per unit time is displayed on the numerical value display 11a. In this way, by knowing the count value per unit time, whether or not the proper lifting capacity is exhibited, in other words, whether or not the gap between the lifting cylinder body 22 and the guide rail cover 33 is appropriate. Alternatively, it can be determined whether or not the wear state of the conveyor belt 25 is appropriate. Note that the count value per unit time may be switched and displayed by a changeover switch or the like so that it can be displayed on the numerical indicator 11a for each ball passage 35a to 35g.
[0022]
Further, for example, there are many accidents in which foreign matters (for example, nails, screws, coins, etc.) are mixed into the introduction rod 30 and balls are not guided to any of the ball passages 35a to 35g. Since the sensors 50a to 50g corresponding to the ball paths 35a to 35g that are not guided no longer detect the passage of the ball, the presence or absence of the detection signal is indicated by the indicator 11b provided corresponding to each of the ball paths 35a to 35g of the display device 11. To that effect. In the case of FIG. 5, since only the third indicator 11b is turned off, it is notified that the passage of the ball is not detected in the ball passage 35c. In such a case, the passage detection is performed. When a predetermined time (for example, 1 minute) elapses after the signal disappears, a display drive signal is derived from the control circuit 10 to the warning lamp 12 to notify the store clerk of clogging in the ball passage 35. . As a result, troubles such as breakage of the conveyor belt 25 and the cloth belt 37 due to foreign matter, or overload on the motor 27 due to foreign matter can be prevented in advance, and wastefulness of transport can be known. As shown in the figure, when there are seven rows of ball paths 35, the driving mode of the warning light 12 when a ball passage failure is detected in the first and second rows, and a ball passage failure is detected in the third to fourth rows. The way of driving the warning lamp 12 when it is done may be made different so that the clerk should take different measures. Further, when a ball passing defect is detected in five or more rows, the motor 27 of the conveyor belt 25 may be controlled to automatically stop. Of course, the motor 27 may be automatically stopped even when only one row of ball passing defects is present.
[0023]
As mentioned above, although the structure and effect | action of the ball polishing lifting apparatus 20 which concern on embodiment were demonstrated, according to this embodiment, the conveyance belt 25 and the feeding cylinder main body 22 which are made to circulate around the lifting cylinder main body 22 by the motor 27 are demonstrated. A pachinko ball is sandwiched between a cloth belt 37 attached to a guide rail cover 33 which is attached so as to cover a belt circumferential surface on one side and which is formed with a plurality of rows of ball passages 35 for lifting pachinko balls in a single row. Thus, in the ball polishing and lifting apparatus 20 that polishes and lifts the pachinko balls, a sensor 50 that detects the presence or absence of the passing of the balls in each of the ball trains that are fed along the ball passage 35 is provided in the upper part. Since the detection signal from the sensor 50 is input to the control circuit 10 as drive control means for driving and controlling the lifting device, each row of the ball paths 35 is based on the detection signal of the sensor 50. It is possible to know the situation.
[0024]
Specifically, as shown in FIG. 5, a display 11b corresponding to each ball path 35 is connected to the control circuit 10 serving as a drive control means, and displays whether or not there is a detection signal from the sensor 50. By displaying on the vessel 11b, it can be seen at a glance whether or not balls are being fed to each row of the ball passage 35. For example, only the third row that is lit in the figure has no ball lifting operation. , It can be understood that a foreign substance that obstructs the intrusion of the ball is mixed in any part of the row.
[0025]
Further, as shown in FIG. 5, a numerical value display 11a for displaying numerical values is connected to the control circuit 10 as drive control means, and the number of detection signals from the sensor 50 per unit time is displayed on the numerical value display 11a. Thus, it can be understood whether or not the proper lifting ability is exhibited.
[0026]
Further, as shown in FIG. 1, a stopper device 7 is connected to a control circuit 10 as a drive control means to block the inflow of pachinko balls by a motor 8 as an electric drive source at the lower part of the ball polishing and feeding device 20. On the basis of a command of the operation switch 9 as a start operation means operated at the start of business, after the motor 27 starts to be driven, the motor 8 as the electric drive source is driven to release the stopper device 7 after a predetermined time has elapsed. The sensor 50 detects a passing ball after the stopper device 7 is closed by driving the motor 8 as the electric drive source based on the command of the operation switch 9 as the end operation means operated at the end of business. By stopping the driving of the motor 27 when a predetermined time elapses, the pachinko ball starts to be lifted smoothly at the start of business. It is possible, there is no reliably be remaining pachinko balls in the ball polishing pumped device 20 at the close of business.
[0027]
In the above-described embodiment, the proximity type sensor 50 is illustrated. However, a light emitting / receiving photoelectric switch may be used, and the mounting position thereof may be a position where each ball row 35 can be measured. , Anywhere. Further, the content of the control operation performed by the control circuit 10 based on the input from the sensor 50 is not limited to the above embodiment, and a desired operation may be performed by freely creating a program. Further, the display device 11 may be provided in an appropriate place of the pachinko island stand 1 that can be seen from the outside, in a management room of a game hall, or the like, instead of inside the lifting device storage unit 3.
[0028]
