Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a high-speed instantaneous large-volume dosing machine.

As a ball dispensing machine for a pachinko parlor, a number of alignment grooves into which a plurality of balls enter and align are provided radially on the board surface, and an alignment board that is connected to a motor and rotates horizontally is provided, and the alignment board is rotated at a predetermined angle. A ball dispensing machine that counts and discharges a predetermined number of balls is in practical use.

This type of ball dispensing machine utilizes the centrifugal force generated by the rotation of the alignment plate to quickly align the balls prior to counting and to discharge the balls during counting, and the ejected balls are almost instantaneously moved from the alignment groove to the ball receiving hole. is discharged to.

Therefore, in order to naturally adjust the movement of the ejected balls at this ball socket, the ball socket is expanded horizontally, and at this ball socket, the ball is secured by a ball stopper ridge on the cover. This prevents balls from flowing into the alignment grooves that have fallen out, but the closer this ball stopper protrusion is to the center of the alignment plate, the more balls will flow into each alignment groove at once after passing the ball receiving opening. It takes time for the balls to stabilize in each alignment groove, and the rotation angle until they are ejected in this stable state becomes small.

Furthermore, in a configuration in which many balls leave the ball retaining protrusions and flow into the alignment groove at once, the movement of the balls on the alignment disk becomes locally large, and the movement of the alignment disk may lack smoothness.

This invention was made in view of the above-mentioned points, and the balls gradually flow into the alignment groove immediately after the balls pass through the ball receiving opening, and by the time the balls pass the ball receiving opening, the balls in the alignment groove are no longer in the alignment groove. The object of the present invention is to provide a ball dispensing machine that almost completes the inflow and achieves accurate, smooth, and high-speed operation.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an alignment plate, the upper surface of which slopes gently downward from the center to the periphery, and has a large number of alignment grooves 2 into which a plurality of balls A enter and align, leaving the center part, and partition walls 3 are erected radially. It is formed. The alignment board 1 is supported on a machine stand 5 by a support shaft 4 provided at the center of the lower surface, and is connected to a motor 7 via a transmission mechanism 6 to rotate horizontally.

Reference numeral 8 denotes a ball socket mounted on the machine base 5, and the front surface of the alignment groove 2 of the alignment board 1 is opened within the range of this ball socket 8. Reference numeral 9 denotes a cover that covers the alignment board and is made of a transparent material. 10 is a ball tank connected to the ball introduction hole 11 provided in the center of the cover 9, in which a large amount of balls A can be stored.
The balls A flow down onto the alignment plate from between a ball guide protrusion 12 in the shape of a chevron, which is protruded in the ball introduction hole at the center of the alignment plate.

Therefore, in this invention, the depth of the alignment groove 2 is set to about 1/3 of the ball diameter, the upper part of the ball A is made to protrude upward, and the ball retaining protrusion 13 provided on the lower surface of the cover is positioned on the alignment groove. A is formed in a series by changing the position from a position closer to the center of the plate to closer to the periphery of the plate in the direction of rotation of the alignment plate.

In Fig. 3a, the starting end of the ball stopper ridge 13 has a circular arc part 13a which is partially concentric with the alignment plate 1, and the whole has an outward bulge shape, so that the ball A moves relatively immediately after the ball A is ejected. The ball A is designed to flow into the alignment groove 2 by increasing the size of the ball A.

FIG. 3b similarly has a circular arc portion 13a partially concentric with the alignment groove 2 at the starting end of the ball stopper ridge 13, and is formed in a straight line as a whole, so that the ball A The purpose is to move the balls A into the alignment groove 2. In addition, the shape of the ball stopper protrusion can be arbitrarily set as required.

In addition, 14 in the figure is a ball abutment projection provided on the lower surface of the cover in front of the ball socket 8 and corresponding to the alignment groove entrance.
When the ball A collides with this, the ball A is forced to flow into the alignment groove 2 in front of it, and a void is created in the rear, so that the ball A can freely move and flow into the alignment groove 2.

In this invention, as described above, the ball stopper protrusions on the cover that fit into the rows of balls in the alignment groove are moved from a position closer to the center of the alignment plate to closer to the periphery of the plate and are formed in a series, so that the balls can be easily removed immediately after the balls are discharged. The ball naturally flows into the alignment groove where the ball has passed, and the inflow is almost complete by the time it passes the ball receiving part, so the stable time for the ball to flow into the alignment groove is faster, and it is better than continuous high-speed operation. No measurement errors occur, and since the shape of the ball-stopping protrusion can be freely set, it can be adapted to the best conditions according to the usage conditions, and has the effect of smoothing the counting operation.
