Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ball lending machine that automatically lends out pachinko balls, and in particular, uses only mechanical means without using electrical means to dispense a predetermined number of coins into the machine. This invention relates to an automatic pachinko ball lending machine that lends out pachinko balls.

(Prior Technology) Conventionally, the mainstay of this type of ball lending machines has been automatic ball lending machines using electrical means such as solenoid valves, micro switches, and relays. In view of this, pachinko ball rental machines are installed between pachinko machines and incorporated into a series of pachinko ball supply systems, so that pachinko balls can be rented out at nearby locations. However, in order to solve various problems such as the problem of installation space of pachinko ball rental machines, the need for specialized technicians for electrical installation and troubleshooting, and the fact that they are large and expensive, automatic ball rental machines without power supply have been developed. A machine was devised, but while this type of machine was small and inexpensive, the following drawbacks were pointed out. In other words, the first condition is to accurately count the number of pachinko balls according to the coins inserted, and it is also required to operate accurately and have no failures. There will naturally be a difference in performance between an electric type, which has an operating end that operates by hand, and a mechanical type, which has to rely on energizing means such as the weight of a coin, and it is difficult for the mechanical type to satisfy these requirements. I couldn't do it.

(Problems to be Solved by the Invention) The present invention is an automatic ball lending machine having a purely mechanical configuration, without using any electrical means, and which accurately counts the number of pachinko balls for each inserted coin. In addition, there is no malfunction due to continuous coin insertion, and the main parts of the sprocket wheel are concentrated to eliminate malfunctions, and the starting lever releases the restraint of the cam sprocket wheel using the coin continuous throw lever and intermediate lever. The purpose of this invention is to provide an automatic pachinko ball dispensing machine with a novel configuration.

(Means for Solving the Problems) The mechanism of the automatic ball lending machine for pachinko of the present invention consists of a disk that engages with pachinko balls supplied to a ball passage and counts their revolutions, and a disk that faces into the coin passage and inserts coins into the machine. A coin repeating lever has a coin locking part and a lead groove that rotates by pushing down the collision part to moor the next coin, and a lead pin, a stop pin, an auxiliary pin, and an engagement groove that engage with the lead groove. an intermediate lever, and a starting lever that has a coin receiving part that descends with the weight of the inserted coin, temporarily holds the coin, and further descends to drop the coin, and is provided with a starting pin that engages with the engagement groove. The disc has a convex control cam having an engagement stepped portion formed with a spirally curved stepped portion on its surface, and a repeating cam having a partially cut out portion is provided on the same axis. A sprocket wheel with a cam is formed, and when the intermediate lever is not in operation, the stop pin of the intermediate lever engages with the engagement step of the control cam, and when the intermediate lever is not in operation, the lead pin of the intermediate lever is engaged with the lead groove of the coin series lever. The starting pin of the starting lever, which descends due to the weight of the inserted coin, is interlocked with the intermediate lever via the engagement groove, and the repeated coin tossing lever via the lead pin and lead groove of the intermediate lever. The restoring timing of the lever is configured to be linked by a restoring pin that imitates the continuous throw cam.

(Function) The repeated coin toss lever, which is rotated counterclockwise upon impact of the inserted coin, anchors the next coin to its locking portion. The lead pin of the intermediate lever, which was engaged with the vertical groove of the lead groove during non-operation as described above, is engaged with the horizontal groove.

Next, the inserted coin comes into contact with the coin receiving portion of the activation lever, and the weight of the inserted coin causes the activation lever to rotate counterclockwise and descend. The activation pin of the activation lever is interlocked with the intermediate lever that engages with the engagement groove, and the lead pin that has engaged with the vertical groove is free from rotational restriction of the intermediate lever, so the stop pin of the intermediate lever is interlocked with the intermediate lever that engages with the engagement groove. The distance required to remove the joint portion is sufficiently satisfied, and the restraint of the cam-equipped sprocket wheel is released.

The stop pin that slides into contact with the control cam of the cam-equipped sprocket wheel further lowers the lowered activation lever, causing the temporarily held coin to drop.

Next, the stop pin that slides into contact with the inside of the control cam rises together with the restoring force of the starting lever, and the stop pin re-engages with the engagement step, causing the cam-equipped sprocket wheel to move. One cycle is completed by counting and discharging a predetermined number of pachinko balls for one coin until the machine is restrained.
