Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention can be applied to many conventional pachinko machines as well as many pachinko machines expected to be developed in the future.
This invention relates to a prize ball ejecting device for a pachinko machine.

(Prior Art) Pachinko machines are designed so that when a game ball enters a grand prize slot, a predetermined number of balls are discharged into a saucer.

It takes a predetermined amount of time to eject the prize ball, and in recent years, techniques for shortening this time have become popular. By the way, there are at least two types of prize ball ejecting devices currently available: The first method is to make the passage through which the balls to be discharged pass through (so that only one ball can pass through at a time, and the cross-sectional dimensions are such that two balls cannot pass through at the same time), and a solenoid is installed at any position above or below the passage. A protruding stopper (shutter) is provided.

In this method, the lower stopper is closed and the upper stopper is opened, and the balls flow into the passage from above, and a predetermined number of balls are introduced until they reach the second stopper. A predetermined number of balls stored between these two upper and lower stoppers are discharged by stopping the inflow of balls, firstly closing the upper stopper and opening the lower stopper. . In this method, a predetermined number of balls must be secured between the two upper and lower stoppers.

The advantage of this method is that when the two stoppers are opened and closed in a mechanically interlocked manner, it reliably prevents more than a predetermined number of balls from being ejected (for convenience, referred to as outflow). It is. However, there is a problem in that it takes time to sequentially open and close the two stoppers in order to eject a predetermined number of balls when a prize is won. In other words, although the outflow of balls can be reliably prevented, it takes time to prepare the appropriate number of balls, and if the next prize is won during this preparation process, there is no way to respond. be.

Another method does not provide a stopper at the upper part of one passage, but only the lower part, and when the stopper provided at the lower part is opened, the number of balls ejected is detected by a sensor. It is. In other words, there is no stopper in the upper part, but the balls are always stored in the path of the lower stopper, and when a prize is won, the lower stopper is opened and a sensor is used to count the number of balls. It counts. This method has the advantage of not requiring any preparation time since it is always in the passage, and has good responsiveness.

However, this method has the problem that if the solenoid mechanism provided in the membrane as a mechanism for opening the stopper does not return and stops, the balls will flow out as long as there is a supply of balls.

In conventional pachinko machines, there was no solenoid mechanism to deal with this situation.

(Problem to be solved by the invention) In this way, in conventional pachinko machines, there was no countermeasure mechanism for all the events of the solenoid mechanism, so if the solenoid mechanism were to be in such a state, , balls will continue to flow out as long as they exist in the Pachinko machine or are supplied to the Pachinko machine.

Generally, when a situation like this occurs, either a store employee notices it due to sounds or other noises and takes action by shutting down the pachinko machine, or the balls that were acquired through the game are lost due to the malfunction. There was a problem in that it was difficult to distinguish between the ball and the ball.

The present invention has been made in view of this point. Even if the solenoid mechanism suffers from the above-mentioned symptoms, a predetermined number of balls or a few more than the predetermined number can be ejected (
The purpose of the present invention is to provide a prize ball discharging device that does not cause the prize balls to be discharged (outflow).

(Means for Solving the Problems) The present invention provides a first method for solving the problems described above.

5), and the pawl 51 that protrudes in the event of a failure is provided facing the second plate 64.

(Function) With such a configuration, by appropriately setting the ratio (reduction ratio) of the rotation speed of the sprockets 71 to 71 (second sprocket 56) and the rotation speed of the rotation support shaft 62 side, a predetermined number of rotations can be achieved. When a ball 12 is ejected, the first plate 63 or the second plate 64 will be scooped up, and the claw that protrudes from the second plate 64 in the event of a failure. 51 engages to prevent the ball 12 from flowing further.

An outflow prevention device 20 is provided at an upper portion of the device 1, and a stopper mechanism 15 is provided at a lower portion thereof. For the sake of convenience, the stopper mechanism 15 will be explained first. A notch 21 (Fig. 1) is provided between the ball removing member 91 and the connection gutter 87 (16th [A)], and a portion thereof is inserted into this notch 21. A first sprocket 22 is provided.

This first sprocket 22 is formed integrally with the latch 23 and the rotating plate 104, and is attached to the support shaft 24. The teeth 105 of the ratchet 23 and the detection holes 106 of the rotary plate 104 are provided in numbers corresponding to the four parts 25 of the first sprocket 22, and the balls 12 falling into the recesses 25 are fitted one by one as shown by the arrows.

5 to stop discharging.

A pawl 29 formed on a first member 28 of an arm 27 that rotates about a shaft 26 faces the ratchet 23 . The arm 27 is ilF! with the claw 29 to the right. It consists of a B material 28 and a second member 3o that rotates around an 8-axis shaft 26 between materials. The details of this part will be explained with reference to FIGS. 4 and 5. The first member 28 and the second member constituting the arm 27
Each member 30 is provided with L-shaped protrusions 11 and 32, and both ends of a coiled link 33 whose intermediate portion is wound around the shaft 26 are engaged with these protrusions 31 and 32.

This coil link 33 allows the first member 28 and the second member to
The member 30 is biased in a direction toward which it approaches.

The second member 30 has a shaft 34 protruding from its middle portion,
The lower end of a plunger connecting arm 36 protruding from the solenoid mechanism 35 is pivoted here. A weight 37 applies a force to the second member 30 in a clockwise direction in FIG. A latching solenoid is used for the solenoid mechanism 35.

As shown in FIGS. 1 and 2, a part of the arm 27 is provided with a water link 47 that rotates around a shaft 46, and a stepped portion 48 formed in that part The arm 27 is positioned so as to be able to come into contact with the receiving portion of the weight 37. The lower end of the vertical link 5o is pivotally attached to the end of the horizontal link 47 opposite to the shaft 46 by a shaft 49, and the upper end of the vertical link 50 has a second arm whose tip is formed into a claw 51. 52 and shaft 53. The second arm 52 is supported by a shaft 54 and pivots about this shaft 54. A stopper bin 55 is provided in a portion adjacent to the guideway 11 to restrict the rotation range of the second arm 52.

A notch 57 (FIGS. 1 and 3) is provided in the taxiway 11 so that a part of the second sprocket 56, which will be described next, faces into the taxiway II.
The sprocket 56 is positioned so as to face the recess 58 on the outer periphery, and is provided to rotate around a shaft 59. It is inserted into the shaft 59 or boss +10 from the wall +09 of the guideway 11. One end of the shaft 59 is supported by a bearing portion 111 (FIG. 2) of the mounting frame 97.

A small-diameter gear 60 that rotates together with the second sprocket 56 is supported on the shaft 59, and this gear 60 is connected to the gear 50 on the outflow prevention device 20 side through a ball removal gutter 112 provided in the mechanism frame 81. It meshes with a large-diameter gear 61 having about three times as many teeth. The gear 61 rotates around a rotating shaft inserted into the mounting frame 97 of the outflow prevention device 20, and a first plate 6 is provided on the side surface of the gear 61.
3 are provided, and are designed to rotate together with the gear 61. A second plate 64 is supported on the rotation support shaft 62 adjacent to the first plate 63 . This second plate body 64
is rotatably supported by a rotating support shaft 62, and therefore hangs down under its own weight in a free state.

This second plate body 64 has a protrusion 6 facing toward the first plate body 63.
5 (see FIG. 11, which will be used in the explanation of the operation described later), by increasing the number of teeth of the gear 61 in an appropriate ratio to that of the gear 60, the number of rotations of the first plate 63 can be increased. It rotates by being scooped up by the protrusion 65 or the first plate 63 at a fraction of the time. A claw 5I formed at the tip of the second arm 52 mentioned above faces the second plate 64.

As a result, the second arm 52 rotates while being rotated while being scooped by the second plate 64 or the first plate 63,
When the pawl 51 protrudes toward the shaft 62, it protrudes in front of the second plate 64 that is rotating at that time, and engages with it to prevent its rotation.

This device configured as described above operates as follows. The state shown in FIG.
, the stopper mechanism 15 is activated to complete dispensing the ball 12, and the solenoid mechanism 35 is activated to release the flansha connecting arm 36 together with the plunger 43.
and pull up the claw 2 provided on the first member 28 of the arm 27.
9 has been engaged with the ratchet 23. nail 29
When the ball 12 is engaged with the ratchet 23, the first sprocket 22, which is integral with the ratchet 23, is also prevented from rotating, and the ball 12 will not flow from there in the r direction.

Next, details of the solenoid mechanism 35 will be specifically explained.

As shown in FIGS. 2 and 6, the main body frame 113 of the solenoid mechanism 35 is made of a U-shaped metal plate.
13 is attached to a metal mounting plate 38. and,
Inside the main body frame 113, an attraction coil 40 and a return coil 41 are wound in two layers, each of which is independently energized. A fixed iron core 39 or a main body frame 113 is fixed to the upper part.

A plunger 43 is provided within the body frame +13, and the plunger 4
3 and the attraction coil 40 and return coil 41, a coil frame 114 is interposed. The plunger 43 is inserted into the hole 42 so that it can move forward and backward, and the suction coil 40
A macnet 45 (permanent magnet) is provided below the return coil 41. The tip of the plunger 43 is covered with a resin member 44, and is connected to the plunger connecting arm 36 by pins 1!5. The resin member 44 at the tip of the plunger 43 is attached to a metal mounting plate 38.
When the plunger 4 comes into contact with the stopper part 116 of
Make sure to form a gap between the tip of 3 (
(See Figures 8 and 9). This is to adjust the magnetic flux (magnetic force) acting on the plunger 43 of the mucknet 45.

Note that FIGS. 6 to 9 show the solenoid mechanism 35,
The drawing is such that it is easy to understand the relationship of the stopper mechanism 15.

Next, the operating state of the solenoid mechanism (latching solenoid) 35 will be explained based on the ejection of prize balls with reference to FIGS. 6 to 9. Figure 6 shows the suction bow coil 40. The pawl 29 of the arm 27 is engaged with the ratchet 23 in a non-energized state together with the return coil 41, indicating a state in which the ejection of prize balls is stopped. In the non-energized state, the plunger 43 is attracted to the fixed iron core 39 by the magnetic flux (magnetic force) of the Macnet 45 in the direction of the dotted line arrow, and the holding force (attraction force) of the plunger 43 is
FPI is thicker than FSI due to the plunger 43 and the weight of each member applied to the plunger 43. FPI > FSI
becomes.

Next, FIG. 7 is an explanatory view until the plunger 43 protrudes. In Figures 15 and 16, the winning slot 669
The winning game ball in the person prize device 67 passes through the winning ball path 84, and upon detection by the winning confirmation mechanism 18, the main body control circuit 17 sends a short pulse (50 m5 to 100 m5) to the return coil 41, and the magnetic flux in the direction of the solid line arrow Happened McNett 4
5 generates a magnetic flux in the direction of decreasing the magnetic flux (magnetic force) of the holding force FPI in the direction of the dotted line arrow, and the magnetic flux (magnetic force) due to the Macnet 45 is weakened, and finally a reversal of the force of FPI < FSI occurs, and the plunger 43 will stand out. As a result, the engagement between the ratchet 23 and the pawl 29 is released, resulting in the state shown in FIG. 8, and the prize ball is ejected.

FIG. 8 shows a state in which the prize ball is being ejected, and shows a state in which the resin member 44 at the tip of the plunger 43 comes into contact with the stopper part 115 of the metal mounting plate 38 and projects by a stroke S. In FIG. 7, the plunger 43 has a holding force FPI
In order to maintain the protruding state of the plunger 43 after the plunger 43 is protruded by overcoming the force of Plunger 43
There is a need to overcome the downward holding force. For this purpose, the stopper part 1 of the Macnet 45 and the metal mounting plate 38 is
16 form a magnetic circuit shown by a one-dot chain line. As described above, leakage magnetic flux is generated between the resin member 44 and the contact plate 38, and an appropriate holding force FS2 is achieved.

Next, a transition state when the attraction coil 40 is energized from the static state (non-energized state 8) in which the plunger 43 protrudes in FIG. 8 will be explained with reference to FIG. 9. When the detection sensor 107 detects whether a predetermined number of prize balls have been ejected, the main body control circuit 17 sends a short pulse (50+*s~
100■S) is sent. The attraction coil 40 is wound so as to generate a magnetic flux in the opposite direction to that of the return coil 41, so it generates a magnetic flux in the direction of the solid line arrow, and the magnetic flux generated by the magnet 45 (in the direction of the dotted line arrow) Since the combined suction force FP3 is generated and is greater than the holding force FS2, the plunger 43 is sucked. As a result, the ratchet 23 and pawl 29 are engaged, and ejection of the prize ball is stopped.

As described above, the solenoid mechanism 35 operates according to its principle of operation by alternately passing pulsed current through the attraction coil 40 and the return coil 41, so that the four plungers and the plunger connecting arm 36 are drawn together with the action of the magnet 45. A latching sole is used to keep the device in the raised position as well as the lowered position.

As shown in FIG. 1, the solenoid mechanism 35 is activated, the arm 27 is rotated counterclockwise, and the pawl 29 or ratchet 23 is rotated.
When engaged with the second member 3 of the arm 27, the horizontal link 47 or step 48 located at the upper part of the arm 27
Since it is pushed up to 0, this force overcomes the weight of the vertical link 50, and the second arm 52 also rotates counterclockwise about the shaft 54. In this way, the nail 51
deviates from the rotation locus of the second plate 64 and does not prevent its rotation.

As a result, even if the second sprocket 56 is rotated by being scooped by either the second plate 64 or the first plate 63, the second sprocket 56 will not be affected in any way.

The arm 27 is divided into a first member 28 and a second member 30, and these are connected by a coil splinter 33 whose both ends are secured to protrusions 11 and 32 provided on each. Even if the pawl 29 provided on the first member 28 receives an impact when it engages with the rotating ratchet 23 to stop it, this impact will be applied to the coil link 33.
As a result, the transmission to the solenoid mechanism 35 side becomes significantly smaller. Thereby, subsequent operations will be performed smoothly.

In this way, the solenoid mechanism 35 stops the plunger connecting arm 36 in both the raised and lowered positions, so if an unfortunate power outage occurs during a game, the plunger connecting arm 36 will remain protruding. obtain.

FIG. 10 shows the state at that time. In such a case, the prize ball discharging mechanism of the stopper mechanism 15 may fail, or the horizontal link 47 may be moved from the shaft 4 due to the weight of the vertical link 50 etc.
At the same time, the vertical link 50 descends under its own weight, and the second arm 52 is rotated clockwise about the shaft 54 until it comes into contact with the stopper pin 55. This causes the claw 51 to protrude into the rotation locus of the second plate 64.

The operation of this part is the most important part of the present invention. This will be explained with reference to Figures 1+ to 14. ] As mentioned above, the first plate 63 is integrally attached to the gear 61, and the second plate 64 is rotatably supported by the rotation support shaft 62. The claw 51 of the second arm 52 is
It is provided at a position where the plunger 43 comes into contact with and engages with the second plate 64 when the plunger 43 protrudes (FIG. 10).

Under such conditions, when the gear 61 rotates clockwise as shown by the arrow, the first plate 63 scoops up the second plate 64 which is hanging down due to its own weight. The state in FIG. 11 shows a state in which the plunger connecting arm 36 is attracted together with the plunger 43 (same as in FIG. 1), and the claw 51 does not protrude into the rotation locus of the second plate 64. Therefore, the claw 51 never engages with the second plate 54.

In the state shown in FIG. 11, the claw 51 does not engage with the second plate 64, so even if the first plate 63 or the second plate 64 is scooped up, the rotation of the gear 61 is not affected in any way. No problem. If the solenoid mechanism 35 or the plunger connecting arm 36 is projected together with the plunger 43 and stops due to a power outage, etc., the claw 51 of the second arm 52 or the second
(see Fig. 12 for Fig. 10), the first plate 63 or the second plate 6
4 (when changing from the state shown in Fig. 12 to the state shown in Fig. 13), the second plate 64 rotates as shown in Fig. 14 (to be more precise, the second plate 64 It rotates and falls from the state shown in Fig. 13 due to its own weight, and this is transferred to gear 61.
(The first plate body 63 integrated with the second plate body 63 comes from behind and pushes the back of the second plate body 64), and at that time, the claw 51 or the second plate body protruding forward of the second plate body 64. 64, and the rotation of the gear 61 is prevented via the first plate member 63 which is in contact with the plate member 64 from the back side.

Therefore, the large diameter gear 61. The second sprocket 56 is stopped via the small diameter gear 6o, thereby preventing the ball J2 from flowing out. As described above, the large diameter gear 61 rotates at a reduced rate of, for example, 1.3 with respect to the small diameter gear 50 (see FIGS. 1, 2, and 1O) that is integrated with the sprocket 56. Recess 58 of second sprocket 56
By appropriately setting the number of (that is, the number multiplied by 3 or a slightly larger number that is close to the maximum discharge amount), the ball ■2 discharge prevention 1F function of the second subblock 56 can be This means that the number can be set to almost match the maximum amount of emissions.

The embodiments described above are for the case where the ball is ejected when it enters the winning hole, but the present invention is not limited to this, and as outlined above, it can be used for pachinko When the machine is equipped with a ball lending function, it can also be applied to the mechanism for dispensing the borrowed balls.

(Effects of the Invention) Since the present invention is a prize ball discharging device for a pachinko machine configured as described above, a latching solenoid is used in the solenoid mechanism, which requires a short energization time, and furthermore, the ball can be ejected in the event of an unexpected power outage, etc. There is an advantage in that it is possible to reliably prevent the outflow of balls, which was not possible in the past, when a situation where the ball continues to be ejected occurs. This mechanism consists of only two plates, a claw that abuts and engages one of the plates, and its drive mechanism, and since it is mechanically operated and does not require any electrical circuit, it will last for a long time. I am looking forward to reliable operation over time.
