Description

[Detailed explanation of the invention] (a) Industrial application field The present invention uses a crane platform that can travel along the ceiling of the box and a claw unit that can move along the crane platform, making it possible to receive prizes inside the box. The user performs an operation to align the claw unit to the planar position of the desired prize from among the miscellaneous prizes scattered in a regular manner, and then lowers the claw unit and attempts to obtain it by successfully gripping the prize with the claw. The present invention relates to a prize lifting game machine, and more particularly to an automatic prize position arrival detection device of a crane claw unit, which can automatically stop descending when the crane reaches a prize while descending.

(b) Prior Art Conventionally, the claw unit of the crane machine in this type of prize-hanging game machine has a fixed lowering position. For this reason, for example, if you scatter a lot of prizes in the prize receiver in the box and stack them up to save the time of replenishing the prizes, even if the claw unit descends and comes into contact with the prize, it will not stop and will fall down on top of the prize. The reality is that it is not possible to accumulate a large number of prizes because of problems such as the game getting spoiled and the rope hanging the claw unit deviating from the pulley guiding it.

(c) Problems that the invention aims to solve This invention solves all of the above-mentioned conventional problems at once, and even if a large number of prizes are piled up in the prize holder inside the box, the prizes will not be centered on the lower end where the claw unit touches. By making it possible to maintain a stable, almost erect posture without leaning or falling off the pulley, a large number of prizes can be scattered in the prize receiver in the box, providing an opportunity to select prizes. An object of the present invention is to provide an automatic prize arrival detection device for a crane board claw unit in a prize-hanging game machine, which not only increases game enjoyment by increasing the number of prizes, but also reduces the number of times prizes are replenished, thereby reducing replenishment effort. .

(d) Means for Solving the Problems The present invention has been made by focusing on the problems of the conventional art. a claw unit fixed to the tip of the rope; a slider that slides back and forth depending on the presence or absence of tension due to the suspension of the rope; a microswitch that is turned on and off by the reciprocating movement of the slider; It is an object of the present invention to provide an automatic detection device for detecting the arrival of a prize position of a crane board pawl unit in a prize lifting game machine, in which a means for stopping a rotational drive device is integrally provided in the crane board.

(e) Effects and Embodiments Hereinafter, the structure of one embodiment of the present invention will be explained together with its effects with reference to the drawings.

A reel 2 mechanically connected to a rotational drive device is attached to a mounting plate 1 integrally fixed to a crane board so that its rotating surface is vertical, and one end of a rope 3 is connected to the reel 2. A claw unit 4 is fixed to the other end of the rope 3, and the claw unit 4 suspended from the lower end of the rope 3 is reciprocated in the vertical direction by winding and unwinding operations by the rotational drive device of the reel 2. .

A slider 7 having a slot 6 fitted into a screw 5 attached to a predetermined position of the mounting plate 1 can be slid laterally and reciprocated along the direction of the slot. A roller 8 that contacts the rope 3 is attached to the position, and when the rope 3 that contacts and acts on the roller 8 is loaded with tension due to the suspension of the claw unit 4, the slider 7 is pushed back by the tension, and vice versa. When the tension is released, the rope automatically moves in the three directions on which the repulsive force is always acting.

The slider 7 is provided with a protruding piece 9, and a lever 11 of a micro switch 10 attached to a predetermined position on the mounting plate 1 comes into contact with and separates from the protruding piece 9.
Due to the elastic action of the slider 7, the slider 7 is constantly repelled in the direction of the rope 3 mentioned above.

In this case, the lever 11 of the micro switch 10
It can be implemented in the same way by using a suitable spring instead of the elasticity.

Furthermore, the attachment plate 1 is turned on and off by engaging and disengaging an engaging element 12 fixed to a predetermined lower part of the rope 3 corresponding to a predetermined lifting and holding position of the claw unit 4.
The micro switch 13 that is turned off is fixed.

In the above configuration, a crane board traveling along the ceiling surface of the box is moved forward from the starting position by operating a button at hand to a line where the projection point of the claw unit suspended from the crane board crosses the desired prize position, Next, the claw unit, which can be moved along the crane board, is moved forward to a position above the desired prize position by operating a push button at hand. Up to that point, the operation and operation are similar to conventional general prize-hanging game machines.

At that position, the reel 2 continues to rotate in a direction to unwind the rope 3 wound thereon, so that the claw unit 4 suspended from the rope 3 descends to reach the prize.

When the claw unit reaches the prize, the rope 3 becomes slack, and the tension on the rope 3 caused by the hanging of the claw unit and 4 is released, and the slider 7 is automatically always biased. As a result, the micro switch 1, which had been pressed by the protrusion 9 of the slider 7,
0 lever 11 is opened to cut off the power to the rotational drive device of the reel 2. Thereby, it is automatically detected that the prize has been reached, and the claw unit 4 automatically stops at its descent point.

Therefore, the claw unit 4 assumes a substantially erect posture without falling over the prize. After the claw of the claw unit closes, the rotary drive device turns on and reverses.
The reel 2 rotates in the direction of winding up the rope 3, and as soon as the rope 3 is wound up, tension acts on the rope 3 and pushes the roller 8, which causes the slider 7 to move back and release the micro switch 10. The lever 11 is pushed to return the microswitch 10 to its normal state, and the rope 3 is further wound up until the claw unit 4 is pulled up to the position where the engager 12 comes into contact with the lever of the microswitch 13, as shown in FIG. When the rotary drive is turned off, the microswitch 13 turns off the power to the rotary drive, and the pawl unit 4 is held in that position.

Thereafter, the return movement of the claw unit 4 to the normal position with respect to the crane board and the return movement of the crane board to the normal position are the same as in the conventional general prize-hanging game machine.

(f) Effect of the invention As is clear from the above explanation, when the claw unit descends and reaches any prize in the prize receiver in the box, the arrival is automatically detected and the claw unit is moved to reach the prize. Since the claw unit can be automatically stopped at a certain position and placed in a stable, approximately erect posture, there is no malfunction due to the rope coming off the pulley, and many prizes can be scattered and piled up in the prize receiver in the box. This has excellent practical value, such as increasing the number of prizes to choose from and greatly increasing interest in the game, as well as reducing the number of times prizes are replenished, contributing to labor savings in replenishing prizes. It is something that you have.
