Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a crane game machine, and more particularly to a crane game machine in which a gripping device is operated to catch a prize.

[Conventional technology]

The crane game machine is a device that lowers the gripping device toward the prizes stocked in the game space, grabs the prizes, and conveys the grabbed prizes to the prize outlet. It is used. This type of game device has a carrier that can move in a horizontal plane, a telescopic telescopic tube is hung from the carrier, and a grip claw is attached to the lower end of the telescopic tube. The vertical movement of the gripping claw is performed by winding the wire wound around the winding drum mounted on the carrier, passing through the inside of the expansion tube and connecting to the gripping claw, and winding the wire back and forth. (See Japanese Utility Model Laid-Open No. 61-163686).

[Problems to be solved by the device]

However, in conventional crane amusement machines, regardless of whether the grip claw touches the prize or not, the descent is continued until all the wires in the telescopic tube are lowered. Therefore, even if the gripping claws come into contact with the prize and stop descending, the wire is fed out, the wire is slackened in the expansion tube, and the gripping claw is in a state of crushing. Further, since the conventional carrier travels on the guide rail using the rack and the pinion, the manufacturing cost is high, and it is difficult to move the carrier to an arbitrary position during maintenance.

Therefore, an object of the present invention is to provide a crane game machine in which the wire winding and rewinding device can be stopped when the gripping claw comes into contact with the prize.

[Means for Solving the Problems]

In order to solve the problems of the above-mentioned prior art, a crane game machine of the present invention is a carrier movable on a top plate of a housing in a horizontal plane and a plurality of pipes that are hung from the carrier and nested. Telescopic tube fitted in the form of a wire, a gripping pawl device attached to the lower end of the telescopic tube, a wire lifting device provided on the carrier, and a wire lifting device that is fed out and inserted into the telescopic tube. Wire, a switch operator connected to the tip of the wire and receiving the weight of the gripper device, and the switch operator when the switch operator is displaced relative to the telescopic tube by a predetermined distance in the vertical direction. A switch that is operated by an operator to stop the operation of the wire lifting device.

[Action]

When the gripping pawl device descends and comes into contact with the prize, the grasping pawl device is prevented from descending, but since the gripping pawl device is attached to the telescopic tube, it does not tilt even if it comes into contact with the prize. At the time when the gripper device comes into contact with the prize and stops, the operation of the wire elevating device continues, so the wire is further fed into the telescopic tube. Then, the switch operator is displaced by the wire and vertically displaced relative to the expansion and contraction tube to turn off the switch, so that the operation of the wire elevating device is stopped and the wire feeding is stopped.

A worm 31, a worm gear 32, a wire reel 33,
It is composed of a guide reel 34. This guide reel 34 has a support shaft, as apparent from FIGS. 8 and 9.
It is supported by a free end of a swing arm 36 that can swing around 35, and the swing arm 36 is biased by a spring 37 in the clockwise direction in the figure. The wire 28 is unwound from the wire reel 33, wound around the guide reel 34, then introduced inside the expansion tube 16, and into a cylindrical connector 38 that can move up and down in the pipe at the exit end of the pipe 17d. Are combined. This connector 38 has a receiving hole 38a at the center,
The upper end of a mandrel 41 having a switch actuator 40 fixed to the lower end is connected to the receiving hole 38a. A coil spring 42 is mounted on the switch operator 40 so as to surround the mandrel 41. A limit switch 43 for limiting the descent of the wire is set within the range where the switch actuator 40 moves up and down. In this embodiment, the limit switch 43 is attached to the center of the bracket 19. The limit switch 43 is a normally closed switch incorporated in an electric circuit that drives the wire motor 30. Reference numeral 44 in the figure denotes a cable for supplying power to the opening / closing motor 25.

Since the present invention is configured in this way, when the turning motor 8 is driven, the rubber roller 5 rolls on the circumferential guide rail 6, and the circumferential guide rail 4 turns about the pivot axis 3 and When the carrier moving motor 15 is driven, the drive wheels 12 rotate and the carrier 9 moves left and right along the circumferential guide rail 4. Therefore, carrier 9
Can be moved to any position in the horizontal plane, which allows the gripping and pawl device 20 to approach the desired position via the expansion tube 16. Then, after the carrier 9 is positioned directly above the desired prize, the wire motor 30 is driven and the wire 28 is unwound onto the wire reel 33. Approach towards. Then, when the tip of the claw member 22 of the gripping pawl device 20 comes into contact with the prize, the descent of the gripping pawl device 20 stops at that time, but since the grip pawl device 20 is attached to the expansion tube 16, it becomes It does not tilt when it comes into contact.

On the other hand, since the wire winding and rewinding device 27 is operating at the time when the grip claw device 20 contacts the prize,
The wire 28 is further paid out into the expansion tube 16. Then,
The spring 42, which is no longer loaded with the weight of the gripping pawl device 20 due to the gripping pawl device 20 coming into contact with the prize, expands and urges the switch actuator 40, so that as shown in FIG.
