Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present 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 of a pachinko parlor.

(Prior Art) In pachinko parlors, the balls that players handle during play often fall and scatter on the floor. In order to collect balls scattered on the floor in this manner, the present inventor has proposed a ball collecting device that uses magnets.

As shown in Fig. 3, this bead removal device has an arm 2 made of a pipe extending from a pistol-shaped grip 1, and a suction head 3 rotatably attached to the tip of this arm. Inside, a magnet is attached to a mounting member and movably housed therein, and the mounting member is connected to the operating piece 4 in the grip via a connecting rod.

In the above configuration, under normal conditions, the magnet moves down inside the suction head together with the mounting member due to its weight, the lower surface of the magnet contacts the head bottom plate 3a made of a metal plate, and the magnetic poles are directed outward from the head bottom plate, and the magnet falls to the floor. To pick up the balls, hold the grip part 1 and slide the head bottom plate 3a of the suction head 3 onto the floor, and use the magnetic force of the magnet to attract the ball A to the head bottom plate 3a and pick it up
To remove the head, pull the operating piece 4 with your index finger to pull the magnet in the suction head away from the head bottom plate 3a. The magnetic force of attraction of the ball A to the head bottom plate 3a is drastically reduced, and the ball A is attached to the head bottom plate. 3a
It was made to fall naturally from the top.

In the bead removal device configured as described above, under normal conditions, the magnet in the suction head descends due to its weight and brings its entire lower surface into direct contact with the bottom plate of the head. The magnet, together with the mounting member, can be moved up and down within the suction head very easily by operating the operating piece.

(Problem to be Solved by the Invention) However, after the operating piece is pulled to remove the ball from the bottom plate of the head, that is, after the magnet is pulled away from the bottom plate of the head by operating the operating piece, the force of the fingertip is suddenly applied from the operating piece. When the magnet is pulled out, the magnet momentarily descends within the suction head and impacts the bottom plate of the head, stopping its movement. This collision of the magnet against the head bottom plate is like hitting the head bottom plate directly with the bottom surface of the magnet, and as these strong hits are repeated, the head bottom plate made of thin metal plate gradually deforms, and the magnet is made of ferrite, etc. In such cases, the magnet itself is likely to be damaged, resulting in a decline in the ball collection function.In addition, consideration must be given to the strength of the mounting member to which the magnet is attached inside the suction head to withstand this impact. There are also problems such as the generation of a loud impact sound when it collides with the bottom plate.

This invention was made to solve the above problems, and it alleviates the collision between the magnet in the suction head and the bottom plate of the head, and can withstand long-term use without deteriorating the ball collecting function. The purpose of the present invention is to provide a convenient ball removing device with a simplified mounting structure.

(Means for Solving the Problems) The gist of the present invention to achieve the above object is to connect a gripping portion and a suction head via an arm, and to be attached to a mounting member within the suction head and to be movable. In a ball removing device in which a built-in magnet can be separated from the bottom plate of the head by operation from a gripping part, the mounting member is made of a metal base plate, and the magnet is attracted to the base plate by its magnetic force. The ball catching device for pachinko is characterized in that the magnet and the base plate are integrated by wrapping an adhesive tape from the outer surface of the magnet to the upper surface of the base plate.

(Function) According to this invention, the magnet mounting member in the adsorption head is made of a metal base plate, and the magnet uses its magnetic force to attract the base plate, and the adhesive tape is wound around the base plate from the magnet. By attaching the magnet to the base plate and integrating it, there is no direct contact between the magnet and the bottom plate of the head, eliminating deformation of the bottom plate of the head and damage to the magnet, and simplifying the structure for attaching the magnet. .

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a front view of a partially cut-out device showing an embodiment of the present invention, and FIG. 2 is a perspective view of a magnet and its attachment-related members.

In the figure, parts common to those in FIG. 3 are given the same reference numerals.

In this invention, an elongated metal base plate 7 is used as a mounting member for the magnet 5 in the above-mentioned suction head 3. The tip of the support rod 6 is inserted through the center of the base plate 7 and fixed with a screw, and the base end of the support rod 6 is connected to the operating piece 4 in the grip. Two magnets 5 are attached to the lower surface of the base plate, and these magnets 5 are attracted to the base plate 7 using the magnetic force of the magnets 5.
The base plate 7 and the magnet 5 have the same width.

Reference numeral 8 in the figure is a positioning member for the magnets 5 that are attached back to back at the center of the base plate 7 with the support rod fixed part in between, and is made of a metal plate in a sideways U-shape.
It is attached to the left and right side surfaces of the magnet 5 from its inner end surface to restrict the movement of the magnet 5.

With the magnet 5 attracted to the lower surface of the base plate, adhesive tape 9 is used to wrap the magnet 5 around the base plate 7 to integrate the magnet 5 and the base plate 7.

The adhesive tape 9 used here is preferably a thin and strong one whose base is made of nylon or the like. Further, in the embodiment, a configuration is shown in which the adhesive tape 9 is wound around the base plate 7 from the magnet 5, but instead of this, an elastic rubber tube-shaped adhesive tape may be used.

In the figure, reference numeral 10 denotes a shock absorbing member attached to the outer surface of the head bottom plate 3a, and the material is not particularly limited as long as it has excellent wear resistance in addition to shock resistance. Considering adsorption properties, a sheet-like material with a thickness of about 0.5 mm as thin as possible is preferred from a practical standpoint.

(Effects) As described above, in this invention, the mounting member for the magnet movably housed in the suction head of the bead removal device is made of a metal base plate, and the magnet is attached to the base plate using the magnetic force of the magnet. Since the magnet and the base plate are integrated by wrapping adhesive tape around the base plate from the magnet, the magnet does not directly collide with the bottom plate of the head inside the suction head, thereby preventing deformation of the base plate of the head. It sufficiently protects the magnet itself and can be used for a long period of time, and the structure for attaching the magnet is simple, and the magnet can be used as a general-purpose magnet with a simple shape. Further, when in use, the noise of collision between the magnet and the bottom plate of the head is reduced, making it easier to handle.
