Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a prize ball feeding device in a pachinko machine, etc., and more specifically, the present invention relates to a prize ball feeding device for a pachinko machine, etc. This invention relates to a prize ball dispensing device for dispensing a fixed number of prize pachinko balls (also referred to as prize balls).

[Technical background]

As is well known, in a pachinko machine, when a pachinko ball enters each prize winning device on the game board, it is treated as a safe ball and is then sent to the safe ball processing section from the exit path in the back mechanism set board on the back side of the board, and is then treated as a safe ball. They are processed one by one and discharged outside the machine.

And the back mechanism Sera for each safe ball processing)! The upper prize ball supply section is operated to dispense a fixed number of prize balls. The prize ball feeding section has a close relationship with the safe ball processing section, and the safe balls are always processed one by one at relatively short fixed time intervals, but at an appropriate point within this processing time, It is considered most important to complete the ball cutting and ball filling, in other words, the delivery and storage of prize balls in a timely manner. In particular, when multiple safe balls are generated, each safe ball is processed sequentially, whereas the prize ball supply section
It is an absolute condition to be able to perform the prize ball dispensing operation without delay each time, and for each prize ball dispensing operation, the necessary minimum amount of operational variation from the safe ball handling section side and light operation are required. Ideally, it should be able to operate accurately and easily with force.

[Prior art]

In view of the above-mentioned technical background, there is a technique disclosed in Japanese Utility Model Application Publication No. 61-36680 as one of conventional prize ball feeding devices. In this prior art, a standby gutter in the form of a box type case that is vertically fixed in a predetermined position and communicated with the supply path is not tilted at all, and flow regulating pieces are installed at the inlet and outlet sides of the standby path. The ball cutting and ball packing are performed by opening and closing the drop regulating pieces and the fall regulating pieces mutually using the lifting and lowering of the lifting member that is operated every time the winning ball detection device operates. However, significant problems arise due to the configuration and movement of the lifting member. In other words, since the elevating member is directly connected to the upper end of the elevating rod connected to the rotating piece in the winning ball detection device, it will not receive unnecessary external force other than the elevating operation force during the original elevating movement linked to the elevating rod. In particular, since the lifting rod tends to swing from side to side and the upper end tends to bend, the lifting member receives operating force in an unnecessary direction, causing a so-called stuck state between it and the lifting guide on the standby gutter side. As a result, the inflow regulating piece and fall regulating piece are constrained by the fluctuations of the ascending and descending members, and can perform their proper opening and closing operations in a timely manner and instantaneously. As a result, this resulted in delays and mistakes in cutting the ball and putting the ball in place.

[Summary and purpose of the invention: The present invention was developed in view of the above-mentioned conventional problems. First and second control valves are attached to the inlet and outlet of the case, and a regulating member is attached to the outside of the ball case so as to be able to rise and fall and regulates the opening and closing of the double-split j''III valve. Therefore, it is composed of one cassette 7) type,
The regulating member is connected in a non-coupled manner to the operating member connected to the safe ball processing section, thereby maintaining smooth and effective pushing up of the regulating member and easy descent of its own weight. This is a prize ball feeding device, and an object of the present invention is to ensure light and proper lifting and lowering of the regulating member to prevent the entrance of the ball case.
Both control valves for the outlet are opened and closed quickly in a well-timed manner.
The purpose is to continue properly dispensing and storing prize balls at all times within the processing time for each safe ball.

〔Example〕

A preferred embodiment of the prize ball feeding device according to the present invention will be described with reference to the accompanying drawings. The prize ball feeding device of this example is installed at the upper right of the back mechanism set board S on the pachinko RM side schematically shown in FIG. 1, in association with the safe ball processing device Rino directly below.

To briefly explain the back mechanism cent board S side, a collection chamber 2 for safe balls that covers the main part of the back side of the game board is formed in the center of the board body 1, and a passageway 3 is provided at the bottom of this collection room 2. It is formed. 4 is a discharge path for out balls, 5 is a ball removal path for stored balls, and a terminal path 6 thereof is communicated with the discharge path 4.

In such a set board S, in the safe ball processing device WD, as shown in FIG. are formed spaced apart from each other, and a motor 14, a ball processing body 19, a detection lever 24, 27, etc. are incorporated in the vicinity between both paths 9, 11. Note that the processing chamber 7 is provided with an opening/closing lid 8. The intake passage 9 is formed in the upper part of the chamber 7 and is connected to the exit passage 3.
The outlet 10 is formed downward at the lower end. The discharge passage 11 is vertically arranged on the right side of the chamber 7, has an inlet 12 formed diagonally upward at its upper end, an outlet 13 at its lower end, and communicates with the terminal passage 6 of the cut-out passage 5.

The motor 14 is fixed at the lower left corner of the chamber 7,
A driver 16 is fixed to the shaft 15.

This drive element 16 is continuously rotated at a constant speed in the counterclockwise direction in the figure by a motor 14, and three cam parts 17 and three recesses 18 are formed on the outer periphery of the drive element 16 at intervals of 120 degrees. On the other hand, the ball processing body 19 is approximately 173 circular in shape and transfers safe balls one by one from the outlet IO of the receiving path 9 to the inlet 12 of the discharge path 11, and its center of rotation is at the center of the chamber 7. A circular guide element 20 is pivotally attached to the part, and one receiving part 21 is formed at one end of the outer periphery (the right end in the drawing), and a circular guide element that can be brought into rolling contact with the driver 16 at an appropriately displaced part from the pivot part 20. 22 is pivotally mounted, and a weight 23 is attached to the other end of the outer periphery. The ball processing body 19 is rotated clockwise starting from the position where the ball receiver part 21 is aligned with the outlet 10, and the ball receiver is rotated clockwise from the ball receiver position where the receiver part 21 is aligned with the entrance 12. It will be terminated and suspended for a while. Then, in synchronization with the elapse of the rest time, the ball holder is instantly rotated counterclockwise again, and the ball holder is returned to its position.

During the rotational movement of the above-mentioned ball processing body 19, the first and second detection levers 24, which are approximately L-shaped, are directly pushed by the safe ball.
．． 27 are arranged respectively. The first lever 24 extends its hanging piece 25 toward the outlet 10 side, and the second lever 27
has its hanging piece 28 extended toward the entrance 12 side so that both can detect contact with the safe ball, and utilizes the engaging portions formed on both horizontal pieces 26 and 29 to detect the safety ball. Normally, the second lever 27 is restrained and stationary at a predetermined ball detection position by the first lever 24.

The prize ball feeding device of this example, which is related to the safe ball processing device described above, will be described in detail. This device uses a fixed number of balls for each safe ball (however, the case of an odd number is mainly shown).
As shown in FIGS. 3 to 5, the ball case 31 made of synthetic resin is vertically installed in a predetermined position on the board body 1 so as to be replaceable. First and second control valves 43, 47 that perform large control of the passage, and a regulating device 51 that opens and closes both control valves 43, 47 in conjunction with each processing operation of the safe ball processing device are assembled, respectively. ing. Ball case 3
1, a vertical prismatic cylindrical case body 32 with top and bottom openings.
Two rows of accommodation channels 33 are formed therein, and an entrance 34 formed horizontally on the upper end side of each accommodation channel 33 is connected to each of the two rows of prize ball delivery channels 36 installed in the board body 1. It communicates with a horizontal outlet 38 at the lower end of the delivery path 37, and an outlet 35 at the lower end of each accommodation path 33 is directed toward a prize ball ejection path 39 formed in the board body 1. The ball case 31 includes a recess 40 formed on the board body 1, an engagement piece 41 formed on a side edge of the recess 40, and a locking piece 42 attached to the other side edge of the recess 40. It is easily and replaceably placed in place using a fixing means.

The first control valve 43 is supported so as to be tiltable in the horizontal direction on a support shaft 44 made of a thin metal plate and attached to the outside of the upper end of the case body 32, and one end thereof (left end in the figure). A piece-shaped opening/closing piece 45 is formed at one end for each population 34, and a connecting piece 46 is formed at the other end. Furthermore, this valve 43
is always biased in the closing direction of the inlet 34 due to its own balance. The second control valve 47 is made of synthetic resin and is supported so as to be tiltable in the downward direction with respect to a support shaft 48 attached to the outside of the substantially central part of the case body 32. An opening/closing piece 49 is formed, and a roller-shaped link 50 that also serves as a weight is pivotally attached to the upper end. This valve 47 is always biased in the closing direction of the outlet 35 due to its own balance, and the opening/closing pieces 49 are provided so as to protrude from each other with a height difference of one ball in accordance with the odd number of prize balls. The top surface that comes into contact with is sloped.

The restrictor 51 is vertically pushed up and down against a guide holder 52 made of synthetic resin and attached to the outside of the upper part of the case body 32, and the first control valve 43 is attached to the upper part.
A U-shaped retaining piece 53 that can be engaged with the connecting piece 46 of the second regulating valve 47 with appropriate play is formed on the lower part 6B, and a rectangular regulating piece 54 for the connecting piece 50 of the second regulating valve 47 is formed, respectively. There is. This restrictor 51 is normally biased downward by its own tension and is operated by an operating lever 56. Note that a weight 55 is attached to the base of the retaining piece 53 as necessary, and the side end surface of the regulating piece 54 is made oblique so that it can smoothly contact and separate from the outer peripheral surface of the connector 50. The operating lever 56 is pivotally mounted 58 in a cantilever manner to a pivot 57 fixed to the panel main body l, and one end is connected to the second detection lever 27 in the processing bag HD via a connecting rod 59. The free end portions thereof are inserted between the two pieces 53 and 54, and are connected to the restrictor 51 in a non-coupled manner. Incidentally, the restrictor 51 is raised and lowered in response to the operating lever 56 being switched between the horizontal and upper positions in accordance with the operation of the second detection lever 27.

In this embodiment of the device configured as described above, ball cutting and ball stuffing operations can be performed in conjunction with each safe ball processing operation in the safe ball processing device. That is, when the motor 14 is in the driving state, the ball processing body 19 receives the safe balls in the outlet 10 of the receiving path 9 into the receiving part 21 at the position where the ball receiving part 19 moves as the driving element 16 continuously rotates at a constant speed. Transfer to the ball release position while rotating. In this process, the first detection lever 24 is tilted counterclockwise after contacting the safe ball, and the second detection lever 24 is tilted counterclockwise.
Release the detection lever 27. After the second lever 27 makes contact with the safe ball, it is tilted counterclockwise to a predetermined position, pushing up the connecting rod 59 and pushing up the operating lever 56 on the prize ball feeding device side.
operate instantly. As soon as the safe ball passes, the first and second levers 24, 27 are tilted back to their original positions by their own balance.

Therefore, in this example device, as shown in FIG. 4(b), the restrictor 51 is quickly pushed up as the operating lever 56 changes upward, thereby instantly releasing the first and second control valves 43,47. As a result, the first valve 43 immediately changes its tilt to close and hold the inlet 34 with its opening/closing piece 45, thereby preventing the passage of prize balls from the prize ball delivery gutter 36. On the other hand, the second valve 4 is in a free state.
7 is pushed outward (to the right in the figure) in response to a portion of the prize ball pressure within the accommodation path 32, and retracts the opening/closing piece 49 out of the path. As a result, the exit 35 is opened and the prize ball is sent to the prize ball ejection path 3.
It is discharged at 9.

The prize ball feeding device 2 control valve 47 is returned to its original closed position and the opening/closing piece 49 is positioned at the outlet 35.

Then, at the same time as the second detection lever 27 returns, the operating lever 56 is tilted downward to its original horizontal position, and the regulating device 51 quickly descends under its own weight to push the regulating piece 54 towards the second control valve 47. While abutting the connecting piece 50, the retaining piece 53 is engaged with the connecting piece 46 of the first control valve 43 and pulled down. As a result, the second valve 47 is held in a closed state with respect to the outlet 35, and the first valve 43 is held in an open state with respect to the inlet 34, respectively, so that the prize balls in the prize ball delivery gutter 36 are
4 into the accommodation path 33 and a predetermined number of them are accommodated. However, the ball packing operation is completed while the ball processing body 19 is temporarily paused at the ball release position.

In particular, in the prize ball feeding device of this example, when the engaging piece 53 has substantially released the first valve 43 during the ascending process of the restricting member 51, the restricting piece 54 is still in contact with the connecting piece 50. The second valve 47 is restrained in the closed state, and in the process of lowering the restrictor 51, the retaining piece 53 moves the connecting piece 4 with the play.
6 and opens the first valve 43, the regulating piece 54 has already restrained the second valve 47. Therefore, when the restrictor 51 moves up and down, it is extremely difficult to cut the ball by opening the second valve 47 after closing the first valve 43, and to pack the ball by opening the first valve 43 after closing the second valve 47. If the timing is right, the suitability can continue to be 1. Moreover, since the inlet 34 of the ball case 31 and the outlet 38 of the prize ball delivery gutter 36 are communicated with each other laterally, the impact force when a prize ball is passed into the ball case 31 is reduced by the first and second control valves 43. .47
In particular, both valves 43 and 47 can be opened smoothly and instantaneously.

Another example of the prize ball feeding device of this example is a model for an even number of prize balls shown in FIG.
They are basically constructed in the same manner and are detachable and replaceable, with only slight differences in the shape, fulcrum position, and position of the opening/closing piece 49.

[Summary of the invention]

The prize ball feeding device of the present invention includes a ball case for storing and feeding prize balls, first and second control valves for an inlet and an outlet, and a re-control I.
Since the regulating device for opening/closing the valve is assembled into a single cassette type, the entire device can be compactly assembled on the ultimate side, and can be easily handled and installed quickly and easily. In particular, with regard to the above-mentioned regulating device, the operating member is safe because it is not connected but is connected to, for example, a lever-type operating member that is connected via a link to the safe ball detection member on the safe ball processing device side. Even if vibration or displacement occurs when tilting in connection with ball handling operations,
The restrictor is not affected and can be easily raised and lowered while maintaining an appropriate posture by utilizing the effective field downward movement of the operating member. Therefore, the opening and closing operations of the first and second control wells can be performed smoothly and quickly by following the vertical movement of the regulating device, so that the ball cutting and ball filling can be performed in a timely and accurate manner. f;y
It is possible to completely avoid cutting delays and ball filling defects.
