Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a pachinko ball collecting device that uses magnets to collect pachinko balls (hereinafter simply referred to as balls) scattered on the floor at a pachinko parlor.

(Prior Art) In pachinko parlors, the large number of balls handled by players during play often fall from their hands and scatter on the floor.

Balls are spherical, so if they fall on the floor, they often roll freely on the floor, far away from the point of fall, or roll into a narrow space and get lost. It is extremely troublesome for the owner of the game to find and collect the balls themselves, so at certain times in pachinko parlors, employees collect the balls that are left scattered all over the floor.

Conventionally, to collect balls that have fallen on this floor,
A ball remover has been put into practical use in which an arm of an appropriate length extends from a gripping part, a magnet is attached to the tip of the arm, and balls are attracted to the magnet.

With this type of ball remover, which simply attracts the balls directly to the magnet, in order to remove the balls that have been attracted to the magnet after collection, you must touch the balls directly to remove them. This work is extremely troublesome and time consuming, and there is also the problem of having to touch and handle the balls that have fallen on the floor and become dirty.

Therefore, the main body of the suction head is formed into a sealed box shape, and a magnet is movably built into the box.The magnet is connected to the gripping part via a traction member, and the traction member is operated to move the magnet inside the head. A ball catching device has been proposed that pulls up a magnet and reduces the magnetic force at the bottom of the head that attracts the balls, allowing the balls to fall naturally.

However, when using this ball collecting device to pick up a large number of balls, each ball tends to get as close to the magnet as possible on the outer surface of the suction head.
Some of the balls may become attracted even if they are hung from the attraction surface at the bottom of the head to the bottom of the side wall surface.If the side wall of the head stands up vertically from the bottom, even if the magnet is raised inside the head body, Since the distance between the magnet and the side wall surface does not change, the ball also moves up the side wall surface due to the movement of the magnet, making it difficult for the ball to fall.

(Purpose of the invention) This invention was made to solve the above problem, and it is possible to conveniently pick up balls scattered on the floor by using the magnetic force of the magnet, and also To provide a ball removing device which is convenient to handle and can securely drop all the balls by slightly moving the magnet within the suction head when removing the balls.

(Structure of the invention) Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is a partially cutaway front view of this invention.

In the figure, 1 is a gripping portion, 2 is a pipe-like arm extending from the gripping portion 1, 3 is a suction head attached to the tip of the arm 2, and 4 is a magnet built into the head.

The grip part 1 is formed into a pistol shape and is designed to be easily gripped by four fingers excluding the index finger.

The head main body 5 of the suction head 3 is made of plastic and molded into a long and narrow sealed box shape, with the bottom serving as a suction surface 6, side wall surfaces 7 slanting upward and outward, and a mounting cylinder portion 8 at the center of the top. is provided protrudingly, and the lower end of the arm is inserted into this mounting cylinder part 8, and the retaining protrusion 9 in the mounting cylinder part is engaged with the groove 10 provided on the outer circumferential surface of the arm, and the arm 2 is attached to the arm 2. On the other hand, the suction head 3 is made freely rotatable.

The magnet 4 inside the suction head is connected to an operating piece 12 attached to the tip of the grip via a traction rod 11 inserted into the arm, and can be moved within the head by operating the operating piece 12 with the index finger. There is.

In the normal state, the magnet 4 descends due to its own weight and comes into contact with the bottom of the head, that is, the attracting surface 6, with its magnetic pole directed toward the attracting surface 6.

(Function) In the above structure, when the device grips the gripping part 1 and brings the suction head 3 close to the ball A falling on the floor, the ball A is brought to the suction surface 6 by the magnetic force of the magnet 4. While being adsorbed, many balls A form a chain of balls and are placed in an adsorbed state.

To remove the ball A adsorbed to the outer surface of the head, pull the operating piece 8 with your index finger.
The magnet 4 separates from the attraction surface 6 within the head, and the attraction surface 6
The magnetic force that attracts ball A rapidly decreases, and ball A falls due to its own weight.

(Effect of the invention) In this invention, as described above, the side wall surface 7 of the suction head 3 is inclined upward and outward from the suction surface 6 at the bottom, so that the lower part of the side wall surface 7 in contact with the suction surface 6 at the bottom is Even if the ball A is placed very close to the inner magnet 4 and is attracted, the magnet 4
moves inside the head and leaves the suction surface 6 and rises,
The distance between the magnet 4 and the side wall surface 7 suddenly increases, and the magnetic force acting on the balls A, which had been attracted by the side wall surface 7, decreases drastically, causing all the balls A to fall at once.

Therefore, in the conventional ball removing device of this kind, the side wall is vertically raised upward from the bottom, which is the suction surface of the suction head, and the side wall and the side wall are connected to each other regardless of the position of the magnet within the head. In a configuration in which the distance between the magnets is constant, a ball that is attracted to the side wall will be dragged by the movement of the magnet and will rise up the side wall, making it difficult for it to fall. However, with this invention, all the balls could be reliably dropped just by slightly moving the magnet inside the suction head, making it easy to operate and easy to collect the balls. It has an excellent effect of making work more efficient.
