[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detecting an abnormal height of an obstacle nail implanted in a game board of a game machine such as a pachinko machine.

[0002]

2. Description of the Related Art As a prior art of this kind, for example, there is one in which a gate plate for detecting an abnormality is attached to a conveyor of a game board. The transport conveyor sequentially transports the game board downstream with the front surface facing upward. The gate plate is fixedly installed at a predetermined height position from the transfer surface of the transfer conveyor, and can be brought into contact with obstacles that are more than the allowable maximum height on the game board being transferred. is there.

In this abnormality detection device, if all of the obstacle nails implanted in the previous process are below the allowable maximum height, the above-mentioned game board can be passed through the above-mentioned gate board as it is. On the other hand, if a height abnormality occurs in the obstacle nail implanted in the game board, even if there is only one obstacle, the obstacle nail having the height abnormality contacts the gate plate. Will be. As a result, the conveyance of the game board is automatically stopped, and it is possible to detect an abnormal height of the obstacle nail.

[0004]

By the way, the obstacle nail of the game board is an indispensable element for changing the flowing direction of the hit game ball, and depending on the adjustment, creates a state that is advantageous to the player. It is optional to create a state that is advantageous to the game store. However, it is a major premise that a desired state can be created in the gaming machine by such an adjusting operation when obstacle nails are planted with high dimensional accuracy on the gaming board. For this reason, in the above-described abnormality detection device, it is an important issue how to accurately detect the height abnormality of the obstacle nail implanted in the game board.

However, in the above-described conventional detection apparatus, the veneer forming the game board or the thickness of a resin film called a cell directly affects the detection result. If the cell thickness varies, it becomes difficult to accurately detect an abnormal height of the obstacle nail. That is, when the thickness of the veneer or the cell varies in the direction in which the thickness is small, even an obstacle nail having an abnormally high height will pass through the above-described gate plate. On the other hand, when the thickness of the veneer or the cell varies in the direction in which the thickness increases, even an obstacle nail having a height within an allowable range contacts the gate plate and is determined to be abnormal.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an abnormality detecting device which can always accurately detect an abnormal height of an obstacle nail without being affected by the thickness of a game board. I do.

As shown in FIG. 1, the operating rod 24 a of the stopper cylinder actuator 24 has a conical shape whose tip gradually decreases in size toward the tip, and is formed through a communication hole 21 a formed in the vertical wall 21. It can appear in the G transport area. The holding body 25 has a relatively large coefficient of friction with respect to the game board G, and is formed into a plate shape with an elastic synthetic resin. It is adhered to a wide portion including the portion facing the rod 24a.

The base member 30 includes an oscillating body 31 and a support 3
2 and a pair of legs 33. Oscillator 3
Reference numeral 1 denotes a plate having a shorter width and length than the lateral wall 23 of the outer frame member 20 described above. This rocking body 3
1 is connected to the transport conveyor 1 with respect to the lateral wall 23 by the first hinge means 40 interposed between the transport conveyor 1 and the lower surface of the lateral wall 23.
Are supported so as to be able to swing around a horizontal axis orthogonal to the conveying direction of the sheet. The support 32 is a member having substantially the same length as the rocking body 31 and having an L-shaped cross section. The support body 32 is connected to the rocking body 31 by a plurality of height adjusting bolts 41 interposed between the rocking body 31 so as to adjust the mutual interval with the rocking body 31. The pair of legs 33 are portions extending from both ends of the support 32 toward the respective transport roller chains 2 of the transport conveyor 1, and each of the lower ends has a pair of running rollers 34 at each lower end. The traveling roller 34 is
Each of the peripheral surfaces is supported so as to protrude below the lower surface of the leg 33, and is rotatable around a common horizontal axis orthogonal to the transport direction of the transport conveyor 1. The radius of the running roller 34 matches the allowable maximum height of the obstacle nail P implanted on the game board G.

As is apparent from the drawing, the base member 30 has a bracket 35 on a surface of the support 32 facing the upstream side of the conveyor 1, and a gate below the support 32. A member 50 is provided.

The bracket 35 is mounted substantially at the center of the support 32, and holds a limit switch 36 and an angle adjusting bolt 37. Limit switch 36
Is held by the bracket 35 with the contact 36a facing downward. This limit switch 36
The contact 36a is always protruded downward by the pressing force of a built-in spring (not shown). Contact 36a
Is projected downward, the limit switch 36 is in the ON state, and a detection signal is given to the control means 60. On the other hand, when the contact 36a is pushed up against the pressing force of the built-in spring, the limit switch 36 is turned off, and the detection signal to the control means 60 is cut off. The angle adjusting bolt 37 is attached to an adjusting bolt attaching portion 35a protruding from the lower end of the bracket 35 toward the upstream side of the conveyor 1, and the adjusting bolt attaching portion 35a is provided.
It is possible to appropriately adjust the amount of downward projection from the projection.

The gate member 50 is a plate-like member having a width enough to cover the area where the obstacle nail P is planted in the game board G, and is provided by the second hinge means 42 provided between the gate member 50 and the support 32. The support 32 is supported to be swingable about a horizontal axis orthogonal to the transport direction of the transport conveyor 1. The gate member 50 is provided with a detection bolt 51 at a position corresponding to the limit switch 36 described above. The detection bolt 51 is attached to a detection bolt mounting portion 50 a protruding from the upper edge of the gate member 50 toward the upstream side of the conveyor 1.
It is possible to appropriately adjust the amount of protrusion upward from a. The detection bolt 51 can push up the contact 36a of the limit switch 36 via the head 51a when the lower end of the gate member 50 is swung toward the upstream side of the conveyor 1. On the other hand, when the lower end of the gate member 50 is swung toward the downstream side of the conveyor 1, the contact 36a of the limit switch 36
Is possible.

When the height error of the obstacle nail P implanted in the game board G is detected by the abnormality detection device 10 configured as described above, the following adjustment operation is performed, and the abnormality detection device 10 is detected. Set to standby state. That is, first,
The angle adjusting bolt 37 is appropriately adjusted so that its head 37a is brought into contact with the upper surface of the detection bolt mounting portion 50a, and the gate member 5
By swinging 0, the lower edge of the gate member 50 is set so as to be located on the axis of the running roller 34. Next, the detection bolt 51 is appropriately adjusted so that the head 51a of the detection bolt 51 pushes up the contact 36a of the limit switch 36 with the lower edge of the gate member 50 positioned on the axis of the traveling roller 34. I do. Further, the height adjustment bolt 41 is appropriately adjusted, and the conveyor 1
The height is set so that the peripheral surface of the traveling roller 34 always contacts the front end surface of the game board G conveyed above.

From this detection standby state, the obstacle nail P
Is transported on the conveyor 1, and when the above-described detection position is reached, the distal end surface of the gaming panel G comes into contact with the peripheral surface of the traveling roller. As shown in FIG. 4A, the traveling roller 34 abutting on the front end surface of the game board G rides on the front face g of the game board G while appropriately swinging the base member 30 toward the downstream side in the transport direction. ,afterwards,
Rolling occurs with the peripheral surface always in contact with the front surface g of the game board G.

During this time, if the height of the obstacle nail P implanted on the game board G is lower than the lower end of the gate member 50, FIG.
As shown in (b), the obstacle nail P can pass through the gate member 50 without contacting the lower end. In this case, the base member 30 and the gate member 50
Does not swing, and the contact 36a of the limit switch 36 is held up by the head 51a of the detection bolt 51. That is, in the state shown in FIG.
Does not output a detection signal.

On the other hand, when the height of the obstacle nail P implanted on the game board G exceeds the lower end of the gate member 50, even if the height is one, as shown in FIG. In addition, the obstacle nail P comes into contact with the lower end of the gate member 50. Further, with the subsequent transportation of the game board G, FIG.
As shown in (d), the obstacle P causes the gate member 50 to swing toward the downstream in the transport direction with respect to the base member 30. At this time, the head 51a of the detection bolt 51 is separated from the contact 36a of the limit switch 36 with the swing of the gate member 50, so that the limit switch 36 outputs a detection signal to the control means 60. The gate member 50 is controlled by the control means 60.
Will be detected.

In the case of the present embodiment, the control means 60 which detects the swing of the gate member 50 causes the stopper cylinder actuator 24 to extend and press the tip of the operating rod 24a against the side surface of the game board G. As a result, the game board G is moved to the operation rod 24 of the stopper cylinder actuator 24.
a and the holding body 25, and the conveyance thereof is stopped. At this time, the operation rod 24a of the stopper cylinder actuator 24 comes to bite into the side surface of the veneer constituting the game board G, thereby stopping the transfer of the game board G and simultaneously marking a pressing mark on the game board G. become.

At the same time, the control means 60 turns on the alarm lamp 61 and sounds the alarm buzzer 62. As a result, the worker can recognize that the gate member 50 has swung, and a desired treatment for the obstacle nail P exceeding the lower end of the gate member 50, for example, a height below the lower end of the gate member 50 is achieved. In this way, it is possible to take measures such as driving the obstacle nail P.

Thereafter, when the operator turns on the release button 63, the warning lamp 61 turns off and the alarm buzzer 6
2 stops, and the stopper cylinder actuator 24 is further contracted. As a result, the abnormality detection device 10
Returns to the detection standby state again, and the above-described operation can be repeatedly performed.

Here, in the abnormality detecting device 10, a roller whose radius matches the allowable maximum height of the obstacle nail P implanted on the game board G is used as the running roller 34.
Further, in the above-described detection standby state, the lower edge of the gate member 50 is set to be located on the axis of the traveling roller 34. Therefore, in the operation shown in FIG.
The obstacle nail P passing through the lower end of the gate member 50 is below the allowable maximum height, while the obstacle nail P contacting the lower end of the gate member 50 is exceeding the allowable maximum height. As a result, according to the abnormality detection device 10, it is possible to reliably detect only the obstacle nail P having a height abnormality exceeding the allowable maximum height.

In addition, according to the abnormality detection device 10,
Even when the thickness of the board changes due to the variation of veneers or cells constituting the game board G, or when dust is attached to the lower surface of the game board G, the base member 30 is accordingly attached. The lower end position of the gate member 50 always moves with respect to the front surface g of the game board G,
Is maintained at a constant distance corresponding to the radius of the above, that is, a distance matching the maximum allowable height. As a result, even when the thickness of the game board G varies in a small direction, even when the board thickness varies in a large direction or when dust is attached to the lower surface of the game board G, the thickness is always constant. , Obstacle nail P exceeding allowable maximum height
Only can be reliably detected. Therefore, in the game board G after passing through such an abnormality detection device 10,
The height of the obstacle nail P can be set accurately, and a desired state can be created according to the adjustment work.

In the above-described embodiment, a device for detecting an abnormal height of an obstacle nail installed on a game board of a pachinko machine is exemplified. Of course, the present invention can also be applied to obstacle nails implanted in other game boards. In addition, while the base member is fixedly installed, the game board is transported, but the same effect can be expected in the reverse mode or in the mode of transporting both. is there. In addition,
In the embodiment described above when the game board is transported, the front face of the game board is oriented upward, but the transport is performed by turning the front face of the game board sideways or downward. The posture may be changed as appropriate. However, when transporting the game board in a posture other than the embodiment,
It is preferable to provide a pressing means such as a spring so that the contact portion of the base member always contacts the front surface of the game board.

Further, in the above-described embodiment, the base member is moved in the direction of approaching / separating from the front surface of the game board by swinging the base member. It is not necessary, and for example, the base member may be linearly moved in a direction approaching or moving away from the front surface of the game board. Although a traveling roller is used as a contact portion of the base member,
It is not always necessary to apply a roller. In this case, when the base member is linearly moved in a direction in which the base member approaches or separates from the front surface of the game board, the contact portion does not need to be formed in an arc shape.

Further, in the above-described embodiment, as the detecting means, there is provided a gate member swingably supported on the base member, and a limit switch for outputting a detection signal when the gate member swings. In this case, the detection is performed by detecting whether the obstacle nail has contacted the gate member based on the presence or absence of the detection signal from the limit switch. However, the obstacle nail is directly moved without swinging the gate member. It may be configured to electrically detect that the contact has occurred. In this case, the detection means is not limited to the contact type, but may be any type such as a type that detects by pressure, a type that detects by vibration (including sound), and a type that detects visually. It is possible. It is not always necessary to apply a detecting means provided with a gate member, and, for example, a means for directly and optically detecting an obstacle nail that has reached a detecting portion may be used.

Further, in the above-described embodiment, the transport stop means is provided, and the gate member is swingably supported on the base member. Even when a game board conveyed later collides, there is no fear that the impact force may cause a situation where the obstacle nail is bent. However, the transport stopping means is not necessarily an essential configuration, and it is not necessary to pivotally support the gate member with respect to the base member as described above. In the above-described embodiment in which the transport stop means is provided, since the cylinder actuator configured to mark the pressing mark on the side surface of the game board is applied, the manufacturing history of the game board can be left. However, it is not always necessary to apply the marking. For example, a stopper may be provided on the downstream side in the transport direction of the game board so as to be able to protrude and retract, and this stopper piece may be brought into contact with the tip end surface of the game board. in this case,
As an actuator to move the stopper piece in and out,
Of course, it is also possible to apply something other than the cylinder actuator. When marking is performed, it is not always necessary that the marking is a pressing mark, and other markings such as a stamp may be used.
