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, the board is equipped with a number of radial alignment grooves into which a plurality of pachinko balls enter and align, and is equipped with an alignment board that is connected to a motor and rotates horizontally, 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 before counting and discharge the balls during counting, making it accurate and efficient. The balls being played flow almost instantaneously from the alignment groove to the ball socket, and the ball socket has a relatively horizontally expanded form to naturally adjust the movement of the balls at this ball socket. Therefore, during this period, the inflow of balls into the alignment groove after the balls have passed is blocked by the ball stopper ridges on the cover, and the inflow alignment of the balls starts only after passing the ball receiving opening. It takes time for the alignment to be completed, and the alignment disk is still rotating during this time, and the rotation angle becomes small until the balls are stably ejected into the alignment groove. Therefore, if the balls are slow to flow into the alignment grooves and take a long time, this may cause a counting error. Furthermore, if the balls leave the ball retaining protrusion and start flowing into the alignment groove all at once, the movement of the balls on the alignment board becomes locally large, and the movement of the alignment board also lacks smoothness. .

This invention was made in view of the above-mentioned points, and the ball is gradually introduced into the alignment groove immediately after the ball comes out of the ball receiver, increasing the number of aligned balls. It is designed to realize accurate and smooth operation regardless of size etc.

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

1 is an alignment board whose top surface extends from the center 2 to the periphery 3.
A large number of alignment grooves 4, in which a plurality of balls A enter and align themselves, are formed on the partition wall 5, with the central part 2 being left in the middle.
It is formed by erecting radially.
This alignment board 1 is supported in an exposed manner on a machine base 7 by a support shaft 6 provided at the center of the bottom surface, and a cylindrical portion 8 formed on the bottom surface of the alignment board and a motor 9 are connected via a transmission mechanism 10. , horizontally rotates by a predetermined angle with one operation of the motor 9.

Reference numeral 11 denotes a cover that covers the alignment plate 1, and is made of a transparent material, and the cover 11 hangs in front of the alignment groove of the alignment plate 1 on the periphery of the cover except for the area facing the ball receiving hole 12 attached to the machine base 7, and has balls. A stopper wall 13 is provided in series. Reference numeral 14 denotes a ball stopper protrusion 14 that is provided on the lower surface of the cover 11 in correspondence with the ball receiving opening 12 and that fits into the row of balls in the alignment groove. The position is gradually changed from the beginning to the periphery of the alignment plate to form a divided configuration.

Reference numeral 15 denotes a concave groove provided on the top surface of the partition wall into which the ball stopper protrusion 14 enters, and these grooves are arranged concentrically at different positions with respect to all the partition walls 5. In addition, 16 in the figure is the cover 1
This is a gap formed between the ball stopper wall 13 of 1 and the periphery 3 of the sorting plate, which allows garbage brought onto the sorting plate to fall, and 17 is a garbage receiving groove for receiving the garbage. .

As described above, the ball retaining protrusions 14 of the cover 11 that fit into the rows of balls in the alignment groove 4 are divided into parts, and the balls are provided at different positions starting from the center of the alignment plate. Immediately after the balls are discharged, the balls A start to flow into the alignment groove 4 from which the balls have passed, and this is gradually increased, so that the time when the ball A stabilizes inflow into the alignment groove before the counting operation becomes faster, and the ball A starts to flow into the alignment groove 4 from which the balls have fallen out. Even if the ball is removed from the alignment groove 4, it does not cause counting errors and increases reliability.
The movement of the balls A on the alignment board is not localized violently, unlike when the balls A are introduced all at once, and the counting operation is smoother. Furthermore, there are fewer collisions between the balls and noise generation can be reduced. play.

Claims (1)

[Claims] 1. A large number of alignment grooves are provided radially on the surface of the board, into which a plurality of balls enter and line up, and an appropriate number of alignment grooves are opened in front to the ball receiving opening, and an alignment plate that rotates horizontally, and the alignment plate is covered and corresponds to the ball receiving opening. In a ball dispensing machine equipped with a cover which is provided with a ball stopper protrusion on the lower surface for regulating the balls discharged from the alignment groove, a concave groove into which the ball stopper protrusion is placed is formed on the top surface of the partition forming the alignment groove. It has a divided configuration in which it is provided at multiple locations concentrically with respect to all the bulkheads according to the rows, and the ball stopper ridges on the cover are gradually shifted from a position closer to the center to closer to the periphery of the sorting plate in the direction of rotation of the sorting plate. A high-speed, instantaneous, large-volume ball dispensing machine.
