It is what.

  In the above-described invention, there are three or more vertical plates, ball guide grooves are provided on the contact surfaces of the respective vertical plates, the ball guide grooves are arranged in a plurality of rows, and pachinko balls are sent out in a plurality of rows by two rubber rollers. Can be done. Further, the rubber rollers can be engaged with each other by a rotating member, and one rubber roller can be driven and rotated by a motor, and the other rubber roller can be driven and rotated by the other rubber roller. In addition, a check valve that prevents backflow of the ball can be provided in the middle of the ball guide groove.

  The pachinko ball lifting device according to the present invention inserts two rubber rollers in the horizontal direction of a plurality of superposed vertical plates, so that a gap slightly narrower than one pachinko ball is provided between the outer peripheral surfaces of the rubber rollers. In addition, since the ball guide groove that passes through the gap is provided along the inner surface where the vertical plates come into contact with each other, the pachinko balls fed into the gap can be bitten between rubber rollers and sent out. . Since the pachinko balls caught in the rubber roller are pushed out without rotating, the frictional heat can be greatly reduced and the life of the rubber roller can be extended. In addition, with three or more vertical plates, ball guide grooves are provided on the contact surfaces of each vertical plate, and the ball guide grooves are arranged in multiple rows, so that pachinko balls are arranged in multiple rows with two rubber rollers. Can be lifted by capacity. Further, since the rubber rollers are engaged with each other by a rotating member such as a gear, one drive source is sufficient to rotate them. Further, since the check valve is provided in the middle of the ball guide groove, the pachinko ball in the middle of lifting does not fall down when the rubber roller is pulled out for inspection.

The pachinko ball feeding device 25 includes a plurality of stacked vertical plates 8 and two rubber rollers 1 and 2 inserted perpendicularly thereto. A small gap 3 is provided between the outer peripheral surfaces of the rubber rollers 1 and 2, and ball guiding grooves 4 and 5 are formed through the gap 3. The pachinko ball fed into the ball guiding groove 4 on the front side of the gap 3 is bitten by the rubber rollers 1 and 2 and pushed out to the ball guiding groove 5 on the rear side of the gap 3 to store the upper ball via the transport pipe 28. It is lifted up to the tank 29.

Details of the pachinko ball lifting device 25 will be described with reference to FIGS.
In FIG. 2, 8 is one of the vertical plates (segments) to be superimposed. The vertical plate 8 is provided with two circular holes 35 and 36 in the vertical direction, and a gap 3 slightly narrower than one ball is formed between them. Ball contact grooves 4 and 5 that communicate with each other via the gap 3 are provided on the contact surface of the vertical plate 8. The ball guiding grooves 4 and 5 may be formed only on one side of the contact surface, or may be formed facing each other. The ball guiding grooves 4 and 5 have dimensions that allow one ball to pass through both the vertical width 6 and the horizontal width 7, and the pachinko balls do not swing left and right and up and down.

  In FIG. 3, four vertical plates 8 a, 8 b, 8 c, and 8 d are disposed, and these are brought into contact with each other and are sandwiched between support members 38 and 39. Ball guide grooves 4 and 5 are provided on one of the contact surfaces of the vertical plates 8a, 8b, 8c, and 8d, and a total of three rows of ball guides are formed. The rubber rollers 1 and 2 are mounted so as to be slidable and rotatable through the vertical plates 8, but the two rubber rollers 1 and 2 are provided with three gaps 3 for biting pachinko balls. It is possible to send out pachinko balls in multiple rows.
