Description

  The present invention relates to a ball payout device for paying out a winning ball of a pachinko gaming machine or a ball payout device of a ball rental device, for example, and more specifically, a ball by forward and reverse rotation of a sprocket that rotationally feeds a pachinko ball (hereinafter referred to as a ball). The present invention relates to a ball dispensing device and a gaming machine that eliminate clogging.

Hereinafter, a ball payout device provided in a pachinko gaming machine will be described as an example.
A conventional ball payout device includes, for example, a stepping motor provided so as to be capable of forward and reverse rotation as disclosed in Patent Document 1 and Patent Document 2, and rotates based on the driving of the motor. And an inverted U-shaped passage for rotating and feeding a ball to one side and the other side by a feed claw between annular opposed surfaces of a main case that houses the sprocket. Further, a ball supply path is connected to the upper portion of the passage to receive the ball, a payout passage is connected to one side forming an inverted U-shape at the lower portion of the passage, and a ball removal passage is connected to the other side.

  And when paying out as a prize ball during the game from this ball paying device, if the stepping motor is driven forward and the sprocket is rotated forward, the ball is continuously paid out from the payout passage and the front surface of the pachinko machine. It can be paid out to the tray that protrudes to the top.

  On the other hand, if it is necessary to remove the ball from the upstream storage tank due to inspection of pachinko machines, hole installation, layout change, etc., if the sprocket is reversed based on the reverse drive of the stepping motor, According to this rotation, the balls stored in the storage tank can be guided to the ball removal passage and recovered to the ball recovery device connected to the back side of the board surface of the gaming machine.

  However, in the case of such a ball dispenser, the ball dispensing operation and the ball removal operation are switched by rotating the stepping motor forward and reverse in a state where the ball is in a position where it is dispensed from the feed claw recess of the sprocket. In this case, the direction of rotation of the sprocket is reversed. In this case, a ball may be jammed between the sprocket feed claw and the inner wall surface of the annular passage along the outer peripheral surface of the sprocket.

Japanese Patent Laid-Open No. 3-286791 JP 2000-37535 A

  Therefore, the present invention provides a reliability that can realize rotation feeding that avoids clogging even when the rotation direction of the sprocket is switched in a state where the ball is present in the annular passage when the ball guided to the annular passage is rotated and fed by the sprocket. An object is to provide a ball delivery device and a gaming machine with high performance.

The present invention provides an annular passage that rotates based on the driving of a motor and rotates and feeds a ball in a circumferential direction by a feed claw between an annular opposed surface of a sprocket having a feed claw on an outer peripheral surface and a casing that houses the sprocket. provided, in an upper portion of said casing communicating with said annular passage provided a ball feed port for receiving a ball supplied from above, a the lower portion of the casing balls payout opening for paying out the ball taken into the annular passage downward A ball dispensing device provided, wherein a ball outlet that branches downward from a position on one side of the annular passage is provided, and an annular passage side wall of a branched portion between the ball outlet and the annular passage is opened. The ball passing through the annular passage is provided with an elastic body for avoiding clogging that protrudes from the outer peripheral surface side of the annular passage toward the outer peripheral side of the sprocket while allowing the elastic deformation to protrude. The elastic body is retracted to a position where the ball is allowed to pass by receiving the ball pressure of the ball, and when the ball passing through the annular passage is rotated and fed in the ball dispensing direction, The elastic body is characterized in that the ball is pressed and urged to the sprocket side, and the ball is moved and guided to the position of the recess between the feed claws avoiding the correspondence between the tip of the feed claw of the sprocket and the projection .

By providing the ball outlet in the lower position of the annular passage, it receives rotational force from the sprocket from the upper ball supply port, and rotates and feeds a half-circular ball in the circumferential direction of the annular passage, and is mechanically conveyed. Is rotated and fed. For this reason, if the sprocket is rotated at a high speed, the balls are paid out at a high speed. Therefore, high-speed payout can be realized.

The ball outlet is provided on an annular passage, and is commonly used by providing a ball outlet and a ball outlet in one annular passage. Further, since the ball outlet cannot be opened at the same position as the ball outlet at the lower position, it can be provided by opening downward at a position on one side of the annular passage.

  According to the present invention, the ball can be rotated and fed to one side (forward rotation) and the other side (reverse rotation) of the annular passage by forward and reverse rotation of the sprocket. At this time, since the sprocket is rotated to forcibly rotate the ball, it does not depend on the ball's own weight, and it is not affected by the drop resistance of the ball, and the ball can be discharged at a high speed by the rotational drive of the motor. . Further, by rotating the sprocket forward and backward, a payout operation associated with one rotation direction and a ball removal operation associated with the other rotation direction can be easily performed.

  For example, when paying out a certain number of balls from the ball dispensing device, the motor is driven forward so that the sprocket is rotated forward. As a result, the balls guided to the annular passage are continuously discharged from one of the ball outlets by the rotational feed of the sprocket. Then, when the sprocket rotates by a specified amount, the ball dispensing operation is completed.

  On the other hand, when removing the ball from the ball dispensing device, the motor is driven in reverse to reverse the sprocket. As a result, the ball guided to the annular passage is continuously balled out from the other ball outlet by the rotational feed of the sprocket. Then, when all the balls are removed, the operation for removing the balls ends.

  In particular, in the dispensing operation, when the ball outlet is compared with an inverted U-shaped passage that is not located at the lower position of the annular passage, in the inverted U-shaped passage, the ball guided to the upper ball supply port is placed at the bottom of the annular passage. Since the power cannot be transmitted by rotating the sprocket until the ball is dispensed, the ball dispensing speed is reduced. However, such a problem can be solved by setting the ball dispensing outlet at the lower position of the annular passage.

  The case where the ball dispensing operation and the ball removing operation are executed by switching between the normal rotation and the reverse rotation of the motor has been described. The same operation can be achieved by constructing the operation in the reverse direction.

In addition, even when the sprocket rotation direction is switched in a state where balls are easily clogged with the ball passage opening branched from the annular passage and the ball passage, the elastic body corresponding to the position contacts the ball. It supports elastically and prevents movement in the clogging direction, and works to avoid clogging. For this reason, there is no risk of clogging and a highly reliable and stable rotational feed operation can be executed.

Further, the elastic body during the ball removal operation moves to a retreat position that allows the ball to pass by receiving a pressing force due to the rotation of the sprocket received by the ball, so that the elastic body may be interposed in the annular passage. There is no hindrance to the beading operation, and the continuous beating operation can be continued.

On the other hand, when switching from the ball removal operation to the payout operation, the motor may be switched from the reverse rotation drive to the normal rotation drive. Along with this, the sprocket also switches from reverse rotation to forward rotation, and the ball changes from reverse rotation to forward transfer. At this time, the ball of the annular passage is likely to be displaced at the opening corresponding portion between the annular passage and the ball outlet, but since the elastic body is located at that position and biased toward the sprocket side, the ball is here. Even if guided, the ball is guided to move to the concave position where the sprocket does not correspond to the convex portion. For this reason, the clogging operation is avoided in advance. As a result, even if the sprocket rotation direction is switched in the reverse direction in a state where balls are interposed in the annular passage, a stable payout operation that avoids clogging can be obtained.

  In another configuration of the present invention, the ball payout outlet may be provided with a count detection sensor for counting the number of balls paid out from the ball payout exit, for example, ball count detection using a proximity sensor. It can be composed of sensors.

  According to this invention, it is possible to check the balls paid out from the ball paying exit and count the number of balls paid out by the counting detection sensor provided at the ball paying exit. Furthermore, if both the ball presence / absence detection sensor and the count detection sensor are provided, the current flow of balls in the ball dispensing apparatus can be managed more accurately from both detection signals for supplying and dispensing balls.

  In another configuration of the present invention, a ball presence / absence detection sensor for detecting the presence of a ball guided to the ball supply port may be disposed at the ball supply port, for example, a ball presence / absence detection sensor using a proximity sensor. Can be configured.

  According to the present invention, the presence / absence of a ball guided to the ball supply port can be detected by the ball presence / absence detection sensor provided in the ball supply port. For this reason, rotation control with appropriate payout and ball removal by a sprocket can be performed. For example, when applied to a gaming machine, the presence or absence of balls supplied from a storage tank of the gaming machine can be confirmed. Therefore, empty capture can be prevented. For example, when it is detected that the number of balls is insufficient, it can be detected that the ball has run out or is clogged. At this time, it is possible to regulate the supply operation and the dispensing of the balls.

The elastic body may be configured by a leaf spring having a bulge portion at a central portion, the bulge portion being attached from an outer peripheral surface side to an inner peripheral surface side in the annular passage with one end fixed. it can.

  If the ball dispensing device configured in this way is incorporated in a gaming machine, a gaming machine having a high processing capability with a high ball dispensing speed can be constructed. For example, the present invention can be applied to a prize payout device for a pachinko gaming machine.

  According to the present invention, by providing a ball discharge outlet at the lower position of the annular passage, the balls that are rotationally fed by the sprocket convey the half-circular ball in the circumferential direction of the annular passage and transfer the ball from the top to the bottom of the annular passage Until it is mechanically transported by the rotational force of the sprocket. For this reason, if the sprocket is rotated at a high speed, the balls can be dispensed at a high speed.

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

  FIG. 1 shows the back side of a gaming table 11 of a pachinko gaming machine. A ball hopper 12 is disposed on the upper side of the gaming table 11 on the back side, and a large display device, a control unit, etc. are provided at the center on the back side of the board. A substrate portion 13 is disposed. Further, a replenishment chute 14 is provided above the ball hopper 12 so as to face the upper surface opening, and balls are replenished to the ball hopper 12 from above via the replenishment chute 14. In addition, a payout passage 15 is connected to the lower side of the ball hopper 12, and the balls are paid out to a tray located at the lower front of the game table 11 through the payout passage 15.

  As shown in FIG. 2, the ball hopper 12 integrally connects a storage tank 16 installed in a horizontal shape and a ball dispensing device 17 installed in a vertical shape in an inverted L shape. And by connecting the upper end part of the ball dispensing device 17 to the downstream end part of the horizontally long storage tank 16, both are integrated and the compact unit structure is reduced.

  As shown in FIG. 3, the above-described storage tank 16 has a tapered concave shape whose upper surface is opened, and balls are supplied from an upper supply chute 14 to the upper surface opening portion. Storage is allowed. The ball P stored in the storage tank 16 is rolled by its own weight and guided from the upstream side to the ball dispensing device 17 on the downstream side.

  In this case, in order to allow the balls P to pass smoothly from the upstream side to the downstream side, an alignment passage 18 is formed in the front stage of the ball dispensing device 17. The alignment passage 18 is formed by integrally projecting an elongated alignment passage at the downstream end portion of the storage tank 16.

  By the way, from the bottom surface of the storage tank 16 installed on the upstream side to the bottom surface for delivering the balls to the ball dispensing device 17 installed on the downstream side, the long same inclined passage that goes straight with a gentle inclination in the same inclination direction. L is provided.

  The same inclined passage L is a passage in which the bottom surfaces of the passages that allow balls to roll and pass from the storage tank 16 to the alignment passage 18 are connected with a gentle inclination angle in the same inclination direction. For this reason, the ball rolls gently from the upstream side to the downstream side by its own weight.

Next, the alignment passage 18 will be described.
At the tip of the downstream side of the storage tank 16, one of the walls raised on both sides so that the balls P stored in the stacked state stored in the storage tank 16 are aligned and flowed down in one row. One end of the wall is narrowed to narrow the tip, and the narrow and narrow passage extends long forward, and this extended portion is provided in the alignment passage 18.

  Further, on the upstream side of one of the narrowed walls of the alignment passage 18, there is a steeply inclined surface 18a having a large inclination angle with respect to the passage direction for receiving the ball pressure on the upstream side and reducing the ball pressure. In addition, from the upstream side to the downstream side of the other one wall, there is a gentle throttle inclined surface 18b having a small inclination angle with respect to the passage direction. By differentiating the inclination directions of the two inclined surfaces 18a and 18b, it is possible to make the balls flow down to the downstream side while being dispersed without concentrating the flow direction of the balls in the tank. This prevents the ball pressure from being directly applied to the alignment passage 18.

  Further, the bottom of the alignment passage 18 has several exclusion ports 18c that are opened in a lattice shape to exclude foreign substances. As a result, even if foreign matter is mixed in the storage tank 16, the foreign matter falls from the removal port 18c and is naturally removed when it moves to the alignment passage 18 on the downstream side. For this reason, when the balls P are aligned and passed through the alignment passage 18, only the balls P are always allowed to pass to prevent clogging due to foreign matters.

  Further, as shown in FIG. 4, a top plate 19, a ball crushing mechanism 20, a ball passage restriction mechanism 21, a ball dispensing device attaching / detaching mechanism 17 </ b> A, and a connecting frame 22 are attached to the alignment passage 18.

  As shown in FIG. 5, the top plate 19 is formed by an L-shaped plate at the upper part on the downstream side of the storage tank 16 and having the same shape as the throttle shape on the downstream side of the tank and covering the upper surface of the alignment passage 18. Yes. An L-shaped vertical portion of the top plate 19 is provided on the receiving piece 19 a so as to correspond vertically to the upper part on the downstream side of the storage tank 16.

  Thereby, the upper layer part of the ball which overlaps and moves from the storage tank 16 is received, and the upper layer part of the ball P in a piled state is prevented from flowing. For this reason, only the balls of the lower layer can be made to flow down, and thereafter, the number of balls can be sufficiently reduced and supplied to the downstream side little by little. Thereby, the ball pressure to the downstream side can be further reduced, and a smooth flow suitable for the supply of the balls P from the storage tank 16 to the alignment passage 18 side narrowed down to one row of passages is secured.

  Further, since the top plate 19 is provided, even if the balls P supplied to the storage tank 16 jump vigorously and reach the alignment passage 18 or a ball dispensing device 17 which will be described later, the top plate 19 blocks and does not jump. It does not induce clogging or malfunction.

Next, the crushing mechanism 20 will be described.
The ball crushing mechanism 20 has a shaft support pin 25 installed between a pair of left and right shaft support blocks 23 and 24 arranged in parallel on both sides sandwiching the downstream side of the alignment passage 18, and this shaft support. A crushing lever 26 is suspended from the pin 25, and the crumbling lever 26 is provided in a pendulum-like manner in the direction of the passage.

  As shown in FIGS. 6 and 7, the crushing lever 26 has an upstream side in which an open surface of a U-shaped metal plate faces upward and a shaft support hole 26a opened at one end of the U-shape is suspended at the top. The lower surface opposite to the surface is provided as a crushing contact surface and further inclined in two stages. Among these, a first inclined surface 26b that is steeply inclined is formed on the upstream side with respect to the inclined direction, and a second inclined surface 26c that is also gently inclined on the downstream side with respect to the inclined direction is formed.

  FIG. 8 shows a state in which the ball crushing lever 26 is attached, and the ball crushing levers 26 are connected to and suspended from a set of three corresponding to the width of the alignment passage 18. The crushing lever 26 may be a single piece having a thickness corresponding to the passage width of the alignment passage 18.

  At the front stage of the ball crushing lever 26, there is a front crushing inclined surface 27 which is located above the alignment passage 18 and preliminarily performs crushing in the height direction. The forwardly inclined surface 27 may be interposed between the shaft support blocks 23 and 24 on both sides. For example, it may be provided so as to protrude integrally on the passage surface side of one shaft support block 24. As a forward-disintegrating function of the forward-disintegrating inclined surface 27, a guide function is provided to guide the flow down to the height of two halves alternately with respect to the direction of the alignment passage 18 and to crush the upper surface in advance in front of the ball-disintegrating lever 26. have. For this reason, it has the inclination angle which becomes the height of two balls so that the height direction may flow down in a regular staggered arrangement as the balls roll downstream. As described above, the balls are regulated so that the width direction is one row on the downstream side of the alignment passage 18 and the height direction is staggered in a staggered pattern so as not to overlap two or more heights. In this case, the supply shortage of balls from the upstream side is eliminated by making the height direction into two rows.

  Of the inclined surfaces formed on the outer peripheral surface of the crushing lever 26 positioned at the rear stage of the front crushing inclined surface 27, the first inclined surface 26b is moved forward when the crushing lever 26 is rotated to the uppermost position. The balls introduced here are regulated so as to flow down in a regular staggered arrangement so as to have the same inclination angle as the inclination angle of the inclined surface 27. In the second inclined surface 26c, when the crushing lever 26 is rotated to the lowermost position (when the ball is not in contact), the lowermost surface of the second inclined surface 26c is at a height of one and a half balls. The crushing force is set so that the upper layer balls are reliably brought into contact with each other and arranged in a staggered manner. Further, the slanting action of the ball breaker lever 26 is configured so that the lower inclined surfaces 26b and 26c are easily added downward by the weight of the metal.

  FIG. 9A shows a standby state of the crushing lever 26, and when the crushing lever 26 is in a non-contact standby state with the ball, the front end face 26 d of the lever 26 facing the upstream side collapses forward and the inclined surface 27 is formed. It rests against the locking surface 28 corresponding to the downstream end surface.

  FIG. 9 (B) shows the initial contact state of the crushing lever 26, and among the upper and lower balls that have been sent in a staggered manner in the alignment passage 18 at a height of two balls, The inclined surface 26b comes into contact and provides flow resistance. Thereby, the ball pressure of the upper layer ball applied from the upstream storage tank 16 is reduced.

  FIG. 10A shows an initial crushing state, where the starting end side of the second inclined surface 26c is in point contact with the top of the upper layer ball and the ball crushing lever 26 is pushed up, and the load of the crushing lever 26 is applied to the upper layer ball. Gives the crushing action.

  Further, when the ball rolls downstream, as shown in FIG. 10 (B), the end side of the second inclined surface 26c comes into point contact with the ball P, and the ball breaking lever 26 is pushed up most. At this time, due to the downward load acting on the downstream side of the crushing lever 26, the crushing action of breaking the ball overlap and reducing the ball pressure applied from the upstream side is obtained. As a result, the balls P can be aligned from two to one in a staggered pattern alternately in the height direction as the alignment passage 18 rolls from upstream to downstream.

  As shown in FIG. 11 (A), the balls broken by the ball breaking lever 26 are bent downward from the inclined direction of the same inclined passage L and moved to the curved guide portion 29 that guides the descent in a staggered arrangement. To do. A ball flow lower opening 30 that allows one ball to be taken out is opened below the curved guide portion 29, and balls P are discharged one by one from the ball flow lower opening 30.

  FIG. 11 (B) shows the ball flow down state, the ball rolls along the curved guide portion 29 and descends from the ball flow lower port 30 and is supplied to the ball dispensing device 17 connected below.

  Here, an example is shown in which a load is applied using a metal crushing lever 26, but the entire lever 26 is made of resin, and a heavy metal body is embedded at the downstream end thereof. In any case, it is suitable to make a balance in which the load concentrates on the downstream side.

  If the case where there is no ball breaker lever 26 is considered, for example, as shown in FIG. 12, even if the upper layer balls P1 and the lower layer balls P2 are guided in a regular zigzag shape in the vertical direction of the alignment passage 18, they are externally connected. There is a possibility that the top and bottom may be locked when subjected to an impact, vibration, or the like, which may cause clogging. Therefore, by disposing the ball crushing lever 26, it is possible to regulate the upward movement of the ball and ensure a stable flow of the ball without clogging.

  A ball passage restriction mechanism (see FIG. 4) 21 and an attachment / detachment mechanism 17A for a ball dispensing device are attached to a shaft support block 23 corresponding to the outer surface side of the ball breaking lever 26. The ball passage restriction mechanism 21 is configured by attaching a ball passage restriction knob 31 that can be rotated about 90 degrees on the outer side surface of one pivot block 23.

  The ball passage restriction knob 31 has a knob portion 31a for manual rotation on the outer surface, a knob shaft 31b and an arcuate ball passage restriction arm 31c on the inner surface, and a coiled ball passage restriction on the knob shaft 31b. In a state where the spring 33 is inserted, the knob shaft 31b is passed through the shaft support block 23, the ball passage restriction knob 31 is freely rotated, and the shaft end portion is fixed by a flanged screw 34.

  As shown in FIG. 13, the ball passage restricting arm 31 c hangs downward in a bow shape with a knob shaft 31 b as a pivot. The bow-shaped ball passage restricting arm 31c is rotatably provided between an open position for opening the ball flow lower opening 30 and a closed position for closing. For this reason, the ball passage restriction arm 31c normally waits upward to open the ball flow lower opening 30. At this time, the ball passage restriction mechanism 21 receives the spring force of the ball passage restriction spring 33 from the side surface of the ball breaker lever 26 and jumps out of the alignment passage 18 and retracts. For this reason, the balls guided to the alignment passage 18 are in a state of flowing down to the ball dispensing device 17 below.

  On the other hand, when the ball is to be stopped, it is rotated clockwise (about 90 degrees) while pressing the knob portion 31a, and the ball flow lowering opening 30 is closed by the ball passage restriction arm 31c. When the ball flow lower opening 30 is stopped by the ball passage restriction arm 31c, the tip of the arm 31c is the most downstream ball on the storage tank 16 side, and the most upstream ball on the ball dispensing device 17 side. The boundary between the storage tank 16 and the ball dispensing device 17 is partitioned. This stops the ball from flowing down to the ball dispensing device 17.

  By operating this ball passage restriction mechanism 21, the supply of balls from the storage tank 16 can be switched between passage and restriction. Therefore, normally, the ball passage restriction mechanism 21 is opened to allow the ball to pass from the storage tank 16 to the ball dispensing device 17 below, and the ball is allowed to wait in a dispensing permitted state. Then, for example, when removing the ball dispensing device 17 from the back side of the board surface of the game table 11 for maintenance or occurrence of clogging, the ball passing restriction mechanism 21 is used to stop the ball from the ball flow lower opening 30 prior to the removal. Regulate spillage. For this reason, the clerk can easily switch between the passage and restriction of the ball simply by turning the knob 31a of the ball passage restriction mechanism 21 to open and close. Further, when the ball dispensing device 17 is separated from the storage tank 16 and removed, the ball dispensing device 17 can be easily partitioned, so there is no risk of ball leakage at the connection portion with the storage tank 16.

  As shown in FIG. 14, the attaching / detaching mechanism 17A of the ball dispensing device is attached to the upper and lower guide pins 23a and 23b protruding from the outer surface of one of the shaft support blocks 23 so as to be slidable in the vertical direction. The lock lever 32 is attached in a state of being biased downward by a coil-shaped lock spring 35.

  The lock lever 32 is attached in a state where the lock spring 35 is compressed, and the inner end portion of the lock lever 32 presses the upper part when the ball dispensing device 17 is connected to lock the ball dispensing device 17.

  In this way, when the storage tank 16 and the ball dispensing device 17 are connected, they are attached in a directly connected state by the attachment / detachment mechanism of the ball dispensing device 17. When the lock lever 32 is pushed upward with the fingertip, the lock lever 32 slides upward against the spring pressure of the lock spring 35, the lock is released based on this, and the removal of the ball dispensing device 17 is allowed. . In addition, when the ball dispensing device 17 is applied with the lock lever 32 pushed up, it can be locked and attached.

  Since the ball dispensing device 17 can be easily locked, unlocked and detached as described above, when performing maintenance such as maintenance, the ball dispensing device 17 can be easily removed from the game table 11 for maintenance work. After that, it can be easily installed again.

  The connection frame 22 is provided as a connection member for constructing the ball hopper 12 by integrally connecting both the storage tank 16 and the ball dispensing device 17, and the ball hopper 12 is connected to the game table 11 via the connection frame 22. It is attached to the back side of the unit.

Next, the ball dispensing device 17 will be described.
As shown in FIGS. 15 to 17, the ball dispensing device 17 includes a sprocket 41, a drive motor M, a planetary gear mechanism 42, a ball presence / absence detection sensor S1, a count detection sensor S2, and a rotational position detection sensor S3. And a casing 43 containing them, a side cover 44 thereof, and auxiliary covers 45 and 46 on both sides.

  The sprocket 41 described above has a cylindrical body with one end face closed, and a feeding claw 47 having an asymmetrical claw shape for dividing and feeding balls one by one to the outer peripheral surface of the cylindrical body is equally distributed. Has been established.

  As shown in FIG. 18, a support shaft 48 that protrudes outward from the shaft center portion is projected on one closed end face of the sprocket 41, and a bearing roller 49 is fitted to the support shaft 48. In this state, the sprocket 41 is rotatably supported by being inserted into the shaft support hole 44a of the side cover 44. In the annular direction of the closed end face, a rotational position detecting slit 50 is formed which is divided into equal parts.

  As shown in FIG. 19, an internal gear 51 is formed on the cylindrical inner peripheral surface on the other opening end face side, and the gears 52, 53 of the planetary gear mechanism 42 driven by the drive motor M on the internal gear 51. And the sprocket 41 is driven to rotate.

  The planetary gear mechanism 42 described above includes two planetary gears 52 and 53, which are a first planetary gear 52 and a second planetary gear 53, in the circumferential direction around a sun gear 54 connected to the main shaft of the drive motor M. 41 is disposed in a hollow portion surrounded by the inner peripheral surface of 41. These planetary gears 52 and 53 are meshed with the sun gear 54 and meshed with the internal gear 51 to transmit the rotational driving force from the sun gear 54 to the sprocket 41 via the planetary gears 52 and 53. ing.

  Each of the planetary gears 52 and 53 has a rotating shaft pivotally supported by a fixed disk 55, and the fixed disk 55 is integrally attached to a casing 43 described later while holding the drive motor M. Further, the inner peripheral surface of the sprocket 41 has a rotation guide surface 56 having a smooth surface, and three positioning rollers 57 supported by pins 57a on a fixed disk 55 are provided on the rotation guide surface 56 and the like. It is arranged and supported. As a result, the sprocket 41 is positioned at a fixed position to ensure smooth rotation without fluctuation of the sprocket 41.

  The casing 43 is provided in the shape of a disk that covers the sprocket 41 from one side, and further serves as a motor cover. In the lower circumferential direction of the outer surface of the casing 43, there is an exclusion port 43a that is open for foreign object exclusion. By providing this exclusion port 43a, the foreign matter is dropped and eliminated from the exclusion port 43a.

  On the other hand, a fixed disk 55 that supports the drive motor M and the planetary gear mechanism 42 is attached to the inner side surface of the casing 43, and the side surface 44 that supports the sprocket 41 is covered at a position opposite to the inner side surface. It is connected. Further, an exclusion port 44 b for removing foreign matter is also opened in the lower circumferential direction of the outer side surface of the side cover 44.

  A circular hollow portion 43b is formed in the central portion of the casing 43 for interposing the drive motor. The drive motor M is disposed in the hollow portion 43b in a penetrating state, and the casing 43 and the drive motor M are overlapped in the axial direction. is doing. Thereby, the axial direction (thickness direction) of the ball dispensing device 17 is shortened to reduce the thickness.

  Similarly, the gears 52 and 53 of the planetary gear mechanism 42 are interposed in the hollow portion of the sprocket 41 in the axial direction, and the ball dispensing device 17 is thinned by effectively using the axial space portion.

  An annular passage 58 for rotating and feeding the balls P one by one by the feed claws 47 is formed between the annular opposing surfaces formed between the inner peripheral surface of the casing 43 and the outer peripheral surface of the sprocket 41. Of the annular passage 58, the right half circumference is used as a ball payout passage 58a as shown in FIG. 20, and the left half circumference is used as a ball removal passage 58b as shown in FIG.

  Since the balls P guided to the annular passage 58 are fed one by one as the sprocket 41 rotates, the supplied balls P are continuously discharged without interruption.

  A ball presence / absence detection sensor S1 such as a proximity sensor is disposed in the ball supply port 59 at the entrance opening on the upper surface of the annular passage 58 to detect that a ball has been supplied to the annular passage 58. Further, a counting detection sensor S2 such as a proximity sensor is disposed at the exiting ball outlet 60 that opens to the lower surface of the annular passage, and when the ball is paid out through the annular passage 58, the counting detection sensor S2 is provided. Detects and counts the balls that are paid out.

  Further, a rotational position detection sensor S3 for detecting the slit 50 on the sprocket 41 is provided on the outer surface of the side cover 44 so as to face inward from this, and the sprocket is rotated by the slit 50 rotating integrally with the sprocket 41. The rotational position of 41 is detected.

  The ball removal passage 58b is used when an attendant collects the balls P stored in the storage tank 16 as collection balls. In this case, the left half is located at a position opposite to the ball dispensing passage 58a. It is formed in a circular shape, and the ball dispensing device 17 has both the ball dispensing passage 58a and the ball removal passage integrally formed therein. For this reason, the original ball dispensing passage 58a as the ball dispensing device 17 and the ball removal passage 58b can be provided integrally, and an independent new space dedicated to the ball removal passage is not required.

  By the way, the annular passage 58 has a ball supply port 59 opened at the upper center position of the passage and a ball outlet 60 opened at the lower center position. Further, a ball outlet 61 that branches from the ball passage 58b and opens downward is provided at a side position of the annular passage 58 on the side of the ball passage 58b.

  Among these, by providing the opening position of the ball paying outlet 60 at the center of the lower portion of the annular passage 58, the balls P that are rotated and received by the rotational force of the sprocket 41 from the upper ball supply port 59 are half the circumference in the circumferential direction. The balls are transported and mechanically transmitted from the uppermost part to the lowermost part of the annular passage. For this reason, if the sprocket 41 is rotated at a high speed, the balls can be dispensed at a high speed.

  Further, by rotating the sprocket forward and backward, a payout operation associated with one rotation direction and a ball removal operation associated with the other rotation direction can be easily performed. Further, since the counting detection sensor S2 is disposed at the ball paying outlet 60, it can be detected at a fast timing. For this reason, the detection information can also be speeded up, and accordingly, the balls can be paid out more quickly.

  Further, the presence / absence of a supplied ball can be detected by disposing a ball presence / absence detection sensor S1 at the ball supply port 59. For this reason, when it is detected that there is no ball, it can be detected that a ball has run out in the storage tank or a ball is clogged in the upstream alignment passage, thereby preventing empty intake. Therefore, at this time, it is possible to regulate the ball supply operation and the dispensing. By providing both of these sensors S1 and S2, the current ball flow in the ball dispensing device 17 can be managed more accurately from both detection signals for supplying and dispensing the balls.

  As shown in FIG. 22, a plate spring 62 for avoiding clogging is provided at an opening corresponding portion between the ball outlet passage 58b and the ball outlet 61. The leaf spring 62 has an inverted letter shape, and is attached with a bulging portion 62a at the center thereof fixed from the outer peripheral surface side to the inner peripheral surface side in the annular passage. Then, as shown in FIG. 23 (A), the rotation direction of the ball is from the payout waiting state, and as shown in FIG. 23 (B), the sprocket 41 is reversely rotated (counterclockwise in the drawing) to be interposed in the ball payout passage 58a. When the balls P and the balls P supplied one by one from the ball supply port 59 are rotated and fed in the direction of the ball removal, the balls P are continuously reversely fed toward the ball removal passage 58b as shown in FIG. Is done. Thereafter, as shown in FIG. 23 (D), it reaches the ball outlet 61 from the ball outlet passage 58b.

  At this time, as shown in FIG. 24A, the ball P reaching the ball outlet 61 comes into contact with the bulging portion 62a of the leaf spring 62 when the ball is lowered, and resists the elastic force of the spring 62. Move downward while pressing. Thereafter, as shown in FIG. 24 (B), the ball P that has passed through the leaf spring 62 is lowered to the ball outlet 61 and removed.

  For this reason, even if the leaf spring 62 is interposed at the intersection of the ball outlet passage 58b and the ball outlet 61, during the ball removal operation, the leaf spring 62 retreats to the ball pressure in the ball removal direction from above to below. There is no hindrance to the pulling operation. Therefore, the continuous doffing operation can be continued.

  On the other hand, when switching from the ball removal operation to the payout operation, the motor may be switched from the reverse rotation drive to the normal rotation drive. Along with this, the sprocket 41 is also switched from reverse rotation to normal rotation, and the ball P is changed from reverse feed to forward transfer.

  By the way, unlike the ball payout, there is no need to detect in which state the sprocket 41 is stopped, so even if the ball remains in the annular passage 58, for example, the ball is on standby. When the state is switched to the payout state, the ball may drop into the ball outlet 61 and may be locked between the ball outlet 61 and the feed claw tip of the sprocket 41 to cause clogging.

  However, as shown in FIG. 25 (A), since the leaf spring 62 is located at that position and is biased toward the sprocket 41, even if the ball P is guided here, it is shown in FIG. 25 (B). As shown, the ball P is elastically supported by the leaf spring 62 while receiving the force of the sprocket 41 to allow movement of the ball in the passage space. For this reason, the ball P is not supported at a single point, and is easily guided to move to a concave position that avoids the convex portion corresponding to the tip portion of the feed claw of the sprocket 41. Therefore, clogging is avoided in advance.

  As a result, even if the ball is in a position where the ball is likely to be locked in the vicinity of the ball outlet 61, the ball spring 62 guides the bias. Instead of dropping, as shown in FIG. 25 (C), the ball removal passage 58b is rotationally guided in the reverse direction and switched to a payout operation. For this reason, there is no risk of clogging and a highly reliable and stable rotational feed operation can be executed.

  Next, the principle of avoiding clogging when the sprocket rotation direction is switched to the reverse direction (right rotation direction) with the ball P in the vicinity of the ball outlet 61 is shown in FIGS. This will be described with reference to an explanatory diagram.

m: Vertical vector due to the ball's own weight d1: Vector applied to the ball center (center of gravity) from the contact point of the sprocket tooth tip D: Composite vector given to the ball by m and d1 Here, the composite vector D is a ball Is decomposed into a propulsive force Fs in the direction of travel of the ball and Ft0 opposite to the direction of travel of the ball. At this time, the drag force of the leaf spring 62 becomes Ft1 due to the elastic force of the leaf spring 62,
Fs> Ft1
Have the relationship. As a result, the ball P is pushed upward. As a result, the ball P can be moved and guided to a semicircular concave position between the feed claws that avoids the correspondence of the convex portion of the feed claw tip of the sprocket 41 to avoid clogging.

  By the way, if the ball passage 271 without the leaf spring 62 is considered, as shown in FIG. 27, when the ball P remains in the ball passage 271 and is switched from the ball standby state to the payout state. The ball P falls from the feed claw 47 of the sprocket 41 and the ball P is sandwiched by the feed claw 47 at the position of the ball outlet 61, the pressing force at the tip of the feed claw of the sprocket 41, and the wall surface of the ball removal passage 271. The drag force becomes the same, and as a result, a lock phenomenon occurs, causing clogging.

Next, the ball payout processing operation in the thus configured ball hopper 12 will be described.
In the storage tank 16 of the ball hopper 12 installed at the upper part on the back side of the board surface of the game table 11, a large number of balls are stored in a state waiting for paying out. From this standby state, when a ball payout signal is input from a main control unit (not shown) that controls the entire pachinko gaming machine and the drive motor M is rotated forward (rotated in the clockwise direction), this drive is performed. Based on this, the balls in the storage tank 16 roll by their own weight, flow down through the alignment passage 18 and reach the ball flow lower opening 30. During this time, the balls are aligned in one row and guided to the ball dispensing device 17 on the downstream side.

  In the ball dispensing device 17, the supplied balls P are moved down the annular passage 58 by the rotational feeding operation of the sprocket 41 to dispense a predetermined number of balls. And the paid-out ball P is paid out to the upper plate or the lower plate on the front side of the game table.

  By the way, when a tank switch (not shown) detects that the storage balls in the storage tank 16 are remaining, the supply balls are immediately supplied from the supply chute 14 to the storage tank 16 based on this. From the storage tank 16, the aligned balls P are continuously supplied one by one to the ball dispensing device 17 side.

  Further, when the ball dispensing device 17 is clogged or removed due to maintenance or inspection, first, the ball passage restriction knob 31 of the ball passage restriction mechanism 21 is closed and the ball supply port 59 is closed. Stop the flow down to. If the lock lever 32 of the attaching / detaching mechanism 17A is pushed up in the state where the ball is fixed, the lock is released and the ball dispensing device 17 can be removed.

Next, a processing operation for removing balls existing in the ball hopper 12 will be described.
From the storage tank 16 of the ball hopper 12 to the ball dispensing device 17, a large number of balls P are waiting in preparation for dispensing. When a ball removal signal is input from this standby state and the drive motor M is driven in reverse, the ball P previously supplied from the storage tank 16 in the annular passage 58 of the ball dispensing device 17 is removed by the rotation feeding operation of the sprocket 41. Rotate feed to the side of the passage 58b. Thereafter, the ball removal passage 58b is lowered and guided to a ball collection device (not shown) connected to the back side of the game table 11 from a ball collection collection passage (not shown) connected downward.

  At the time of ball removal, the ball is first extracted from the balls in the ball dispensing device 17. When the balls are dispensed, the balls are sequentially supplied from the storage tank 16 into the ball dispensing device 17, and the balls are sequentially extracted.

  As described above, the balls that are rotationally fed by receiving the rotational force of the sprocket from the ball supply port at the top of the ball dispensing device are rotated halfway from the top to the bottom of the annular passage and receive the rotational force of the sprocket from beginning to end. Therefore, if the sprocket is rotated at a high speed, the balls can be discharged at a high speed in proportion to this. Further, since the clogging opening has a leaf spring for avoiding clogging, the clogging can be completely avoided. Furthermore, since this ball dispensing device is integrated in a reverse L shape with the storage tank, the ball hopper can be miniaturized. Furthermore, when mounting, the ball hopper can be compactly arranged in the upper corner of the back side of the board of the game stand standing upright.

However, the present invention is not limited to the configuration of the above-described embodiment.
