  However, as in the past, in Pachinko Island using a belt conveyor, the conveyor belt and rollers for wrapping the conveyor belt are necessary as its components, which complicates the structure and increases the equipment cost. In addition, since there are many drive points such as transfer of the conveyor belt and rotation of the rollers, there is a problem that a lot of labor and cost are required for maintenance such as maintenance and inspection.

  The present invention has been made to solve the above-described problems. The structure of the present invention is simplified by moving the pachinko balls using vibration instead of transporting the pachinko balls using a belt conveyor. It is an object to provide a pachinko island that can reduce the cost of equipment and simplify maintenance such as inspection and adjustment.

In order to solve the above problems, the pachinko island of the present invention (Claim 1)
In Pachinko Island, where multiple pachinko machines are installed side by side on the island,

It was set as the structure currently formed so that the mounted pachinko ball might be moved toward a conveyance termination | terminus part from the conveyance start end part by the vibration of the said vibration apparatus.

The pachinko island of the present invention (Claim 2)
The pachinko island according to claim 1, wherein each ball supply chute is provided with a ball passing sensor for detecting whether or not a pachinko ball has passed, and the vibration according to the number of ball passing sensors that have detected the pachinko ball passing. It is configured to increase or decrease the rotational speed of the device.

The pachinko island of the present invention (Claim 1) has a pachinko ball transport surface formed on the upper surface of the transport frame by attaching a vibration device to a transport frame elastically supported by an elastic member on an upper part of an island base provided in the upper transport device. The configuration is characterized by a downward slope from the conveyance start end portion toward the conveyance end portion.
In this way, by applying vibration to the transport frame by the vibration device, the pachinko balls placed on the pachinko ball transport surface formed in a downward slope can be moved from the transport start end to the transport end. .

  Thereby, unlike the conventional pachinko island which conveys pachinko balls using a belt conveyor, the structure can be simplified, the equipment cost can be reduced, and maintenance such as maintenance inspection and adjustment can be simplified.

  Further, if the rotational speed of the vibration device is increased or decreased according to the amount of pachinko balls supplied to each pachinko machine through each ball supply chute from the upper conveying device (Claim 2), insufficient supply of pachinko balls is insufficient. It is possible to reduce the number of overflowing balls that are prevented and fall off from the conveyance end portion.

For example, if a pachinko ball is supplied to each pachinko machine from the upper transport device at the same time among a plurality of pachinko machines on a pachinko island, the supply of pachinko balls will not catch up, leading to a supply error of pachinko balls There is a fear.
In such a case, if the rotational speed of the vibration device is increased to increase the amount of movement of the pachinko balls, it is possible to prevent a supply error of the pachinko balls.
On the contrary, when the amount of pachinko balls supplied from the upper transport device to each pachinko machine is small, the number of overflow balls falling from the transport end portion increases if the rotational speed of the vibration device remains high.
In such a case, if the rotational speed of the vibration device is slowed down and the amount of movement of the pachinko balls is reduced, the number of overflowing balls falling from the conveyance end portion can be reduced.

In particular, in the future, it is conceivable to increase the number of balls per 100 yen for the purpose of placing pachinko games more than gambling (for example, 50 or 100 balls per 100 yen, currently 100 yen). Around 25 balls).
In this way, when the number of ball lending increases, it is fully considered that the supply of pachinko balls cannot catch up, and according to the present invention, it is possible to prevent such troubles as supply of pachinko balls. it can.

When a plurality of vibration devices 6 are attached, the vibration speed and vibration phase of each vibration device 6 are formed so as to be independently adjustable. For example, the vibration speed and vibration phase are shifted between the vibration devices 6 and 6. By making adjustments such as generating the vibration, an optimum vibration can be applied to the movement of the pachinko ball 12.

Further, the transport frame 5a is elastically supported so that the pachinko ball transport surface 50 formed on the upper surface thereof is inclined downward from the transport start end M toward the transport end N.
When the pachinko ball transport surface 50 is a horizontal surface, simply applying vibration to the transport frame 5a may cause the pachinko ball 12 to dance on the pachinko ball transport surface 50 and not move. By forming it in a gradient, the pachinko ball 12 to which vibration is applied is made to roll toward the conveyance end portion N.
The downward gradient is considered to be appropriate in the range of about 0.5 / 100 to 2/100.

The ball receiving plates 5b and 5b are provided on both sides of the transport frame 5a so as to extend in the left-right direction at the top of the island 1 and have an upper surface continuous with the pachinko ball transport surface 50 of the transport frame 5a. Standing side plates 53 and 53 are provided along the outer edges of the surfaces 52 and 52.
In this embodiment, both ball receiving plates 5b, 5b are connected by a bowl-shaped frame 54, and the conveying frame 5a is elastically supported by the spring 51 inside the bowl-shaped frame 54. The conveying surface 50 and the ball receiving surfaces 52, 52 of the ball receiving plates 5b, 5b are formed to be continuous.

The ball supply chutes 5c and 5c are provided on the outer edges of the ball receiving plates 5b and 5b, and are used to supply the pachinko balls 12 to the respective pachinko machines 16, and above the pachinko machines 16, the vertical plate 53 It is attached by being fitted into a notch portion formed in, and is connected to a prize ball storage tank (not shown) provided on the back surface of the pachinko machine 16 by a bellows hose 17.

  A transparent cover 11 is detachably provided between the compatible side plates 53 and 53 so as to cover the pachinko ball conveying surface 50 and the ball receiving surfaces 52 and 52.

Therefore, the used pachinko balls 12 discharged from the respective pachinko machines 16 are polished from the discharged ball collection path 9 through the lifting device 2 and transferred to the supply ball tank 3. The circulation is repeated by the flow chute 3a supplied to the upper conveying device 5, supplied to each pachinko machine 16 through the upper conveying device 5, and again discharged from each pachinko machine 16 to the waste ball collection path 9.
The overflow ball that has fallen from the conveyance end portion N of the upper conveyance device 5 is returned from the overflow ball collection path 9a to the discharged ball collection path 9.

  In the upper transport device 5, the pachinko balls 12 from the replenishment ball tank 3 are supplied to the pachinko ball transport surface 50 of the transport frame 5a. The vibration device 6 applies vibration to the pachinko ball transport surface 50. And since the pachinko ball conveyance surface 50 is formed in a downward slope, the pachinko ball 12 placed on the pachinko ball conveyance surface 50 can be moved from the conveyance start end M toward the conveyance end N.

Further, in the upper conveying device 5 of the pachinko island A, each ball supply chute 5c is provided with a ball passage sensor S for detecting whether or not the pachinko ball 12 has passed.
This ball passage sensor S uses a micro switch that detects the passage of the pachinko ball 12 in contact with or without contact with the pachinko ball 12, and is provided among the ball passage sensors provided in each ball supply chute 5 c of the upper transport device 5. The rotation speed of the vibration device 6 is increased or decreased according to the number of ball passing sensors S that detect the passing of the pachinko balls 12.

FIG. 4 shows a control system block diagram of the rotational speed of the vibration device 6 described above.
A detection signal from a ball passage sensor S provided on each ball supply chute 5c is input to the control unit 7, and the motor rotation number (high speed rotation, medium speed rotation, A control signal of three stages (low speed rotation) is output.
The control unit 7 includes a CPU 70 that performs control processing, a ROM 71 that stores various control programs and data executed by the CPU 70, a RAM 72 that is used as an operation area by the CPU 70, and an input / output port 73.
Thus, the control unit 7 receives the detection signal from the ball passage sensor S that detects the passage of the pachinko ball 12, and when the number of detection signals is within the set range, the control motor 7a of the vibration device 6 is turned off. A signal for instructing to rotate at a medium speed is output, and if the number of detection signals is larger than the set range, it is determined that the supply amount of pachinko balls is large and the drive motor 6a is rotated at a high speed. A command signal is output, and when the number of detection signals is smaller than the set range, it is determined that the supply amount of the pachinko balls is small, and a signal to command the drive motor 6a to rotate at a low speed is output. is there.

Therefore, for example, when the pachinko balls 12 are supplied to many pachinko machines 16 among the plurality of pachinko machines 16 in the pachinko island A through the ball supply chute 5c at the same time, the supply of the pachinko balls 12 cannot catch up, and the pachinko balls 12 There is a risk of supplying errors.
In such a case, since a large number of detection signals from the ball passing sensor S are input to the control unit 7, a high-speed rotation signal is output from the control unit 7 to the drive motor 6a. The rotation speed is increased, the amount of movement of the pachinko balls 12 is increased, and the supply error of the pachinko balls can be prevented.

In addition, when the amount of pachinko balls 12 supplied to each pachinko machine 16 is small, the number of overflowing balls falling from the conveyance end portion N increases if the rotational speed of the vibration device 6 remains high.
In such a case, if the rotational speed of the vibration device is slowed down and the movement amount of the pachinko balls 12 is reduced, the number of overflowing balls falling from the conveyance end portion N can be reduced.

  In this embodiment, in order to control the rotational speed of the vibration device 6, three speeds of high speed rotation, medium speed rotation, and low speed rotation are set in the drive motor 6a. The above multi-stage or continuously variable transmission may be used.

It is a schematic front view which shows the right half of Pachinko island which is an Example of this invention. It is sectional drawing which shows the upper conveying apparatus of this pachinko island. It is a fragmentary perspective view which shows the upper conveying apparatus. It is a control system block diagram of the rotational speed of a vibration apparatus.
