Anomaly detection device for ball counting machine,

[0008] is provided.

[0009]

[Function] The pachinko ball passing through the lane is detected by the counting sensor. A ball passage monitoring sensor installed separately from the counting sensor detects pachinko balls passing downstream of the counting sensor.

The ball number signal detected and transmitted by the counting sensor and the ball number signal detected and transmitted by the ball passage monitoring sensor are respectively transmitted to the arithmetic means.

The arithmetic means receives the signal from the counting sensor indicating that the pachinko ball has been detected, and then within a time required for the pachinko ball to pass between the counting sensor and the ball passing monitoring sensor in normal time. If it does not receive a signal indicating that a pachinko ball is passing from the passage monitoring sensor, it issues an abnormal signal.

Embodiment An explanation will be given according to FIG. 1 and FIG. 2 showing a central sectional view of an embodiment of the present invention.

Reference numeral 11 is a ball counter. The ball counting machine 11 counts the number of pachinko balls. Therefore, the ball counting machine 11 is provided with a charging port 12 for charging the pachinko balls A to be counted.

Reference numeral 21 is a lane. A plurality of lanes 21 are installed for sorting a large number of pachinko balls to be thrown in at one time, and each lane 21 is divided by a lane partition wall so as to have a width slightly larger than the diameter of the pachinko balls A. Each lane 21 is installed with its tip inclined so that the pachinko ball A thrown into the slot 12 can move in the tip direction. A ball guide is installed on the bottom surface of each lane 21 in parallel with the lane partition wall, and guides the inserted pachinko balls A toward the tip of the lane.

Reference numeral 31 is a counting sensor. The counting sensor 31 is installed in each lane 21 so as to detect the pachinko ball A passing through each lane. The counting sensor 31 projects light onto a pachinko ball A passing in front of the counting sensor 31 and projects light even by a reflection type in which the reflected light reflected by the pachinko ball A is detected to detect the pachinko ball A. It is also possible to use a transmitted light type counting sensor 31 that detects the transmitted light between the pachinko balls A passing in front of the counting sensor 31 and detects the number of pachinko balls. In this embodiment, the counting sensor 31 is a reflection type photo sensor that receives the reflected light, which reflects the light emitted from the light emitting diode, by a photo transistor.

Reference numeral 41 is a ball passage monitoring sensor. The ball passing monitoring sensor 41 is installed in front of the ball drop box 42 at the tip of the lane 21 rather than the counting sensor 31, and is composed of a magnetic sensor or an optical sensor for detecting the material of the pachinko ball A 1. The ball passing monitoring sensor 41 is installed in each lane 21 or in some lanes 21.

Reference numeral 51 is a calculation means. The calculation means 51 is connected to the counting sensor 31 and the ball passing monitoring sensor, and receives the ball number signal detected and transmitted by the counting sensor 31 and the ball number signal detected and transmitted by the ball passing monitoring sensor 41, respectively.

Next, the operation of the embodiment will be described. The pachinko ball A passing in each lane 21 is detected by the counting sensor 31. The ball passing monitoring sensor 41, which is installed separately from the counting sensor 31, detects a pachinko ball A passing in front of it.

The number-of-balls signal detected and transmitted by the counting sensor 31 and the number-of-balls signal detected and transmitted by the ball passage monitoring sensor 41 are respectively transmitted to the calculation means 51, and the calculation means 51 calculates the number of balls respectively.

After receiving the signal indicating that the pachinko ball has been detected from the counting sensor, the computing means 51 monitors the ball passage within the time required for the pachinko ball to pass between the counting sensor and the ball passage monitoring sensor in a normal state. If the sensor does not receive the signal indicating that the pachinko ball is passing, it issues an abnormal signal. Therefore, in order to insert the reflector in front of the sensor and cause the sensor to make an erroneous detection, the reflector reaching not only the counting sensor 31 but also the ball passage monitoring sensor 41 must be used. The sensor only detects the passage of a single pachinko ball if it is inserted in front of the sensor. Therefore, it is necessary for both sensors to detect the pachinko ball A with the same time lag as in the normal state. For that purpose, it is necessary to move the reflector in and out at the same speed as the time lag. However, such actuation is practically difficult and anomalies due to cheating using the reflector are perceived.

[0021]

[Effects of the Invention] Therefore, in this invention, it becomes possible to easily detect an abnormality in the ball counter.
