DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball transfer device capable of transferring a large amount of pachinko balls to a desired place and a connection device therefor.

[0002]

2. Description of the Related Art FIG. 7 is an explanatory view of an example of a conventional pachinko ball conveying device. This pachinko ball conveying device has a sprocket 10 having a plurality of slots 10a formed therearound.
The pachinko balls 14 supplied in a row on the ball passage 12 are fed into the lower part of the downspout 16 by the slots 10a of the sprocket 10.

[0003] The pachinko balls 14 sent to the lower part of the downspout 16 are sequentially pushed up by the pachinko balls 14 sent later, and are lifted up to a predetermined height in the downspout 16.

At the lower end of the downspout 16, a detent stop arm 18, which is bent into an L-shape so as to prevent the pachinko balls 14 in the downspout 16 from returning, urges the bent end 18 a by a spring 20 and vertically. It projects into the gutter 16, and the pachinko balls 14 in the vertical gutter 16 are supported on the upper surface of the bent end 18 a.

[0005]

In the above-described conventional pachinko ball conveying apparatus, when the lifting amount of the pachinko balls 14 is increased, the rotation speed of the sprocket 10 is increased, but the rotation speed of the sprocket 10 is excessively increased. Therefore, there is a problem that the pachinko balls 14 are repelled by the tips of the teeth 10b of the sprocket 10 before the pachinko balls 14 enter the slots 10a of the sprocket 10, so that the pachinko balls 14 cannot be lifted.

[0006] A method of increasing the number of lanes and increasing the lifting amount of the pachinko balls 14 while keeping the rotation speed of the sprocket 10 as it is is conceivable. There was a problem that it was difficult to increase the amount.

A gap having a size such that a foreign substance such as a screw smaller than the pachinko ball 14 is repelled is provided therebetween.

The upper pulley 22b of the belt 24
Pachinko ball 1 on the outside surface of the part
The discharge-side holding members 56 are opposed to each other with an interval substantially equal to the diameter of the nozzle 4. A third side guide (not shown) for guiding the pachinko balls 14 from a direction perpendicular to the holding direction is provided along the discharge side holding member 56 on the side of the discharge side holding member 56. Further, near the upper pulley 22b, a third urging means 58 for applying tension to the belt 24 is provided.

Next, the operation of this device will be described.
When the motor 28 is driven, the lower pulley 22a rotates in the direction indicated by arrow E, and the belt 24 also moves in the direction indicated by arrow F. In this state, when the pachinko balls 14 are supplied onto the supply-side holding member 44, the pachinko balls 14 are interposed between the belt 24 and the supply-side holding member 44 under the lower pulley 22 a while being sandwiched by the second side guide 54. It is sandwiched between and moves around the lower pulley 22a in the direction indicated by arrow G.

Since a gap slightly smaller than the diameter of the pachinko ball 14 is provided between the supply side holding member 44 and the second side guide 54, only foreign matters such as screws and pellets are formed from the gap. Is selectively discharged and removed.
Then, the pachinko ball 14 that has moved around the lower pulley 22a goes up and moves upward as shown by an arrow H while being pinched between the vertical portion 24a of the belt 24 and the holding member 26.

The vertical portion 24a of the belt 24 and the holding member 2
The pachinko ball 14 that has moved upward between the belt 24 and the discharge-side holding member 56 is located above the pulley 22b.
And moves around the pulley 22b while being sandwiched between them, and moves in the discharge direction indicated by the arrow I.

In this transport device, since a large gap is provided between the supply side holding member 44 and the second side guide 54, when the supplied pachinko balls pass below the lower pulley 22a. Then, foreign substances such as screws and abrasive pellets mixed in the pachinko balls fall from the gaps and are removed.

Further, in this transport device, since the outermost periphery farthest from the rotation center of the pachinko ball rolls in contact with the holding member, the pachinko ball is placed on the holding member as compared with the case where the vicinity of the rotation center contacts the holding member. The pachinko balls are conveyed quickly.

FIG. 6 is an explanatory view of a connecting device of the pachinko ball conveying device according to one embodiment of the present invention. As shown in FIG. 6, the connecting device of the pachinko ball conveying device includes adjacent pulleys 22b and 22a. An interposition member 60 interposed so as not to contact the belts 24, 24 between the holding members 26, 26;
It has a connecting member 62 for connecting them in series, and a belt (not shown) for connecting the adjacent pulleys 22b and 22a to each other.

The interposition member 60 has a curved surface 60a for smoothly connecting the front surface of one belt 24 and the front surface of the other belt 24, and the connecting member 62 is a curved surface 6a of the interposition member 60.
0a has a curved surface 62a facing at an interval substantially equal to the diameter of the pachinko ball 14.

By connecting the above-mentioned pachinko ball conveying device with this connection device, the pachinko ball can be conveyed to a desired portion.

[0032]

According to the present invention, even if the rotational speed of the pulley is increased, the pachinko balls do not stop biting, so that the rotational speed of the pulley can be increased to greatly increase the amount of pachinko balls transported. There is an effect that can be.

Further, according to the present invention, the lanes for transporting pachinko balls can be added in parallel, so that
There is an effect that the amount of pachinko balls transported can be easily increased.

Further, according to the present invention, since the heavy driving means can be provided at the lower position, the center of gravity of the apparatus can be lowered, and therefore the apparatus can be easily raised. is there.

Further, according to the present invention, small foreign substances such as screws and pellets are discharged from the lane when a pachinko ball is transported, so that small foreign substances such as screws and pellets can be easily removed. effective.

Further, according to the present invention, since a transport device can be connected, there is an effect that the transport path for pachinko balls can be taken in any direction.
