International Publication No. 2004/026419 Pamphlet

  If the balls are configured to be held in a row, the design tends to be constrained and the storage tends to be large. For this reason, the freedom degree of installation of a ball supply apparatus is low.

  Then, an object of this invention is to provide the ball supply apparatus with a high freedom degree of installation.

  The ball supply device of the present invention is provided at a position higher than the storage part (L) capable of storing the ball (B) and the payout position (P) of the ball of the storage part, and sends out the ball (M). ), A plurality of introduction parts (N1, N2, N3) provided between the storage part and the delivery path, and the balls guided from the storage part to the plurality of introduction parts, respectively, in the delivery path And a drive means (60) for driving the raising means, and the storage portion is connected to each of the plurality of introduction portions to solve the above-mentioned problem.

  According to the ball supply device of the present invention, since the storage portion is continuous with each of the plurality of introduction portions, the ball in the storage portion is stored while being guided to any one of the plurality of introduction portions. The ball moved from the storage part to the introduction part is raised by the raising means and introduced from the introduction part into the delivery path. Thereby, it is possible to hold the balls in a plurality of rows and introduce the balls in any row into the delivery path. Therefore, the storage unit is reduced in size and saves space, and the degree of freedom in installation can be increased. In addition, since the balls in each row are individually introduced into the delivery path, the balls can be introduced into the delivery path without being clogged at the time of introduction.

  In one embodiment of the ball supply device of the present invention, the lifting means includes a plurality of lifting members (51) that are provided in each of the plurality of introducing portions and receive and raise the balls guided to the plurality of introducing portions. And a transmission mechanism (52) for sequentially transmitting power from the driving means to the plurality of lifting members to move the plurality of lifting members in a fixed direction. According to this aspect, the power from the driving means is transmitted via the transmission mechanism and the ascending member moves in a certain direction, so that any one of the balls guided to each of the plurality of introducing portions always rises. Accordingly, any of the balls can be reliably introduced into the delivery path by a series of movements of the raising means.

  In the embodiment provided with the raising member and the transmission mechanism, the detection means (71) for detecting the ball delivered to the delivery path, and the plurality of ascents via the transmission mechanism based on the detection result of the detection means And control means (70) for controlling the drive means to raise one of the members. According to this aspect, when the raising member raises one of the balls guided to each of the plurality of introducing portions and the ball is supplied to the delivery path, it is detected that the ball has been delivered by the detection means. Is done. On the other hand, since it is not detected when the ball is not supplied, the driving means is controlled so that the raising member raises the ball to be raised next. Therefore, the ball can be reliably introduced into the delivery path.

  In the embodiment including the raising member and the transmission mechanism, the transmission mechanism includes a cam (54) for raising the plurality of raising members, a slider (55) to which the cam is fixed, and the plurality of raising members. A guide member (56) provided along a direction for guiding the slider, wherein the driving means includes an arm (61) for transmitting power to the slider, and a motor (62) for rotationally driving the arm. , And the rotation of the arm may be converted into the movement of a slider along the guide member to sequentially raise each of the plurality of raising members. According to this aspect, the slider is moved along the guide member by the rotation of the arm by the operation of the motor, and the cam fixed to the slider pushes up each of the plurality of ascending members. Thereby, each of a some raising member can raise sequentially, and a ball | bowl can be introduce | transduced into a delivery channel | path.

  In the form in which each of the plurality of raising members is raised by the cam, the contact surface (54a) of the cam with the raising member is inclined so as to gradually become higher from the end portion on the side in contact with the raising member. It is formed horizontally after a predetermined height while being formed, and the cam may raise or lower each of the plurality of raising members sequentially according to the reciprocating motion of the slider. According to this aspect, since the contact surface of the cam with the raising member is formed to be inclined, each of the plurality of raising members can be pushed up and raised. Furthermore, since it is formed horizontally after a predetermined height, the raising member to be raised next can be raised while maintaining the height of the raised raising member. On the other hand, when the slider moves in the opposite direction, the raising member descends due to its own weight according to the inclination of the contact surface with the cam. Therefore, the ascending member can be reciprocated.

  In a form in which each of the plurality of raising members is raised by the cam, the slider is provided with a return cam (54b) fixed so as to be in contact with the raised raising member, and the return cam is connected to the raising member. The contact surface (54c) may be formed to be inclined so as to gradually become lower from the end portion on the side in contact with the rising member. According to this aspect, when the slider moves in the direction in which the raising member is lowered, the return cam comes into contact with the raised raising member and pushes down, so that each of the plurality of raised raising members can be reliably lowered. it can.

  In one embodiment of the ball supply device of the present invention, the ball supply unit has a pair of ball supply units (11, 11a) for supplying a ball (B), and the driving means (60) is interposed between the pair of ball supply units. The storage unit, the delivery passage, the introduction unit, and the lifting means may be provided in each of the pair of ball supply units. According to this embodiment, the cost can be reduced by sharing the driving means in the ball supply apparatus having a pair of ball supply units.

  In the embodiment having a pair of ball supply units, the sliders (55, 55a) of the pair of ball supply units are connected to both ends of the arm (61) of the driving means, respectively. The motor (62) may be provided between both ends. According to this embodiment, a motor is provided between both ends of the arm, and both ends of the arm are connected to the slider of each ball supply unit, so that the lifting means of the pair of ball supply units is operated by one motor. be able to.

  In addition, in the above description, in order to make an understanding of this invention easy, the reference sign of the accompanying drawing was attached in parenthesis, but this invention is not limited to the form of illustration by it.

  As described above, according to the ball supply device of the present invention, since the storage portion is connected to each of the plurality of introduction portions, the ball in the storage portion is guided to any one of the plurality of introduction portions. While being stored. The ball moved from the storage part to the introduction part is raised by the raising means and introduced from the introduction part into the delivery path. Thereby, it is possible to hold the balls in a plurality of rows and introduce the balls in any row into the delivery path. Therefore, the storage unit is reduced in size and saves space, and the degree of freedom in installation can be increased. In addition, since the balls in each row are individually introduced into the delivery path, the balls can be introduced into the delivery path without being clogged at the time of introduction.

  The storage unit 20 includes a storage member 21 that can store the ball B, and a partition 22 that is provided inside the storage member 21 and partitions the ball B in a row. A storage region L surrounded by the storage member 21 and the partition 22 corresponds to a storage part. The storage member 21 is provided with a ball receiving port 23 that receives the ball B collected from the pusher field portion PF, and a ball payout port 24 that pays out the ball to the partition member 40. The ball B dropped from the pusher field unit PF is guided to the ball receiving port 23 through a predetermined path inside the game machine G. The storage member 21 is configured to store the balls B in a row in the horizontal direction along the ball moving direction of the rail 30, and the upper portion of the storage member 21 is configured to stack the balls B in the vertical direction. The lower part of the member 21 is configured to be inclined in the direction of the partition member 40. That is, the storage member 21 is configured in a U shape and stores the ball B in a planar shape. The partitions 22 are arranged at intervals such that one ball B can move from a part of the upper portion of the storage member 21 to the ball payout opening 24. The upper end of the partition 22 is not limited to being installed from the upper part of the storage member 21, and may be installed from an arbitrary position such as the lower part of the storage member 21. By providing the partition 22, the storage member 21 stores the balls B in a row in a row for each of the regions partitioned by the partition member 40. In addition, by providing the partition 22 so that the upper end of the partition 22 is lower than the upper part of the storage member 21, the replenishment of the balls due to the balls on the other rows dropping into the rows with fewer balls. Enable.

  The rail 30 is provided with a rail bottom 31 and a rail side plate 32 that is formed perpendicular to the rail bottom 31 and guides the ball B. A delivery area M surrounded by the rail bottom 31 and the rail side plate 32 corresponds to a delivery path. The delivery area M is provided at a position higher than the payout position P of the ball payout opening 24 of the storage unit 20. The rail 30 is connected to the ball supply unit 3 via a predetermined path configured inside the game machine G.

  The partition member 40 is provided so as to extend the partition 22 that partitions the storage member 21. The partition member 40 is formed in such a size that it can partition the balls that are separated from the ball discharge outlet 24 by the partition 22 and are discharged, and can stand by one. The position of the storage unit 20 adjacent to the ball outlet 24 and the position adjacent to the rail 30 are opened so that the ball B can move.

  The raising mechanism 50 is represented by a plurality of raising members 51 a, 51 b, 51 c that raise the ball B guided to each of the regions partitioned by the partition member 40 (reference numeral 51 unless the respective lifting members are particularly distinguished). And a transmission mechanism 52 for raising the raising members 51a, 51b, 51c. FIG. 6 is a view showing the internal arrangement of the raising member 51. The ascending member 51 has a prismatic shape and is disposed so as to be capable of reciprocating in a region where the axial direction is partitioned by the partition member 40. The contact surface 51d with the ball B is inclined so as to become lower toward the rail 30 side, that is, the moving direction of the ball B. A plurality of introduction regions N1 to N3 surrounded by the partition member 40 and the rising member 51 correspond to the introduction portion.

  The transmission mechanism 52 includes rollers 53a, 53b, and 53c that are rotatably provided at lower portions of the ascending members 51a, 51b, and 51c (respectively, the rollers may be represented by the reference numeral 52 unless otherwise distinguished). And a cam 54 that linearly moves the ascending member 51 via the roller 53, a slider 55 to which the cam 54 is fixed, and a rail 56 as a guide member for guiding the slider 55. The rollers 53 are respectively installed at lower portions of the surface of the ascending member 51 on the rail 30 side. A rail 56 is provided along the arrangement of the rollers 53, and the slider 55 is installed on the rail 56 so as to be able to reciprocate. One cam 54 is provided for the plurality of rollers 53. The cam 54 is fixed to the slider 55 at a position corresponding to the roller 53 at a position where the raising member 51 is not raised, and the contact surface 54a of the cam 54 with the roller 53 gradually increases from the end portion on the roller 53 side. It is formed horizontally and is formed horizontally after a predetermined height. Thereby, the raising member 51 is raised to a predetermined height sequentially from the raising member 51a. Furthermore, you may provide the cam 54b of the reverse structure which returns the roller 53 which raised to the original position. The cam 54b is fixed to the slider 55 at a position corresponding to the raised roller 53, and the contact surface 54c of the cam 54b with the roller 53 is formed so as to be gradually lowered from the end portion on the roller 53 side.

  The drive mechanism 60 includes an arm 61 that transmits power to the slider 55 and an electric motor 62 as a motor that drives the arm 61 to rotate. The slider 55 is provided with a guide 57 for transmitting power from the arm 61. The guide 57 is fixed to the slider 55 so that the guide direction of the guide 57 is orthogonal to the slider moving direction of the rail 56. The arm 61 and the electric motor 62 are provided in common to the raising mechanisms 50 and 50a of the ball supply units 11 and 11a. An electric motor 62 is installed at the center of the arm 61. The electric motor 62 drives the arm 61 to be rotatable. Rollers 63 and 63a are provided at both ends of the arm 61, respectively. The rollers 63 and 63a are rotatably in contact with guides 57 and 57a provided in the respective raising mechanisms 50 and 50a. Since the movement range of each roller 63, 63a is limited by the respective guide 57, 57a to be connected, the slider 55, 55a reciprocates according to the driving of the arm 61. In FIG. 3, when the arm 61 is driven to rotate counterclockwise, in the ball supply unit 11, the slider 55 moves in a direction approaching the ascending member 51, and the ascending member 51 is sequentially raised to form a pair of ball supply units 11a. Then, the slider 55 moves away from the ascending member 51a, and the ascending member 51 does not rise. That is, when the drive mechanism 60 is operated, only one of the raising mechanisms of the ball supply units 11 and 11a is driven according to the rotation direction of the arm 61.

  The ball supply device 10 includes a control device 70 that executes control processing of the drive mechanism 60. The control device 70 is configured as a computer unit that combines a microprocessing unit (MPU) and peripheral devices necessary for the operation of the MPU, for example, storage devices such as RAM and ROM. In addition, you may implement | achieve with the control unit which is not shown in figure which performs the various control processing of the game machine G. The ball supply device 10 includes ball sensors 71 and 71a that detect the balls B moving on the rails 30 and 30a, respectively, in the ball supply units 11 and 11a. The control device 70 is connected to the ball sensors 71 and 71a as an input target, and is connected to the electric motor 62 as an output target. Various sensors such as contact sensors and photoelectric sensors may be used as the ball sensors 71 and 71a. Further, the ball supply device 10 includes a position sensor 73 for detecting the position of the rising member 51 by detecting the movement of the small piece 72 provided on the back surface of each of the rising members 51 in each of the ball supply units 11 and 11a. It may be. Various sensors such as a photoelectric sensor may be used as the position sensor 73. Although not shown, each position sensor 73 is connected to the control device 70 as an input target.

  Next, the ball introduction process executed by the control device 70 will be described. Prior to this description, the supply of the ball B to the plurality of introduction regions N1 to N3 will be described first with reference to FIG. The balls B collected from the pusher field unit PF enter the storage member 21 from the ball receiving port 23 of the storage unit 20. In the receiving region L1 where the partition 22 is not installed near the ball receiving port 23, the ball B is received without being partitioned. In the supply areas L2, L3, and L4 partitioned by the partition 22, the ball B enters one of the supply areas L2, L3, and L4. When any of the supply areas L2, L3, and L4 is filled with a ball, there is a high possibility that the supply area L2, L3, or L4 rolls into any other vacant area. The balls B arranged in a row in each of the supply areas L2, L3, and L4 go from the payout position P of the ball payout opening 24 to each of the introduction areas N1 to N3 surrounded by the partition member 40 and the rising members 51a, 51b, and 51c. Guided sequentially. As shown in FIG. 7, the ball B enters the ascending member 51 and waits as it is when the ascending member 51 is in the receiving position Q where the ball B can be received.

  FIG. 8 is a flowchart showing the ball introduction process. First, in step S1, the control device 70 operates the electric motor 62 so as to raise one ascending member 51. The arm 61 is driven to raise the raising member 51 by the operation of the electric motor 62. Due to the movement of the slider 55, the cam 54 pushes up the roller 53 and the raising member 51 rises. When the ascending member 51 rises and moves to the introduction position R where the ball B can be introduced into the rail 30, the ball B moves to the rail 30. As shown in FIG. 9, since the contact surface 51d of the raising member 51 is inclined, the ball B moves by its own weight. Since the raised ascending member 51 blocks the ball dispensing outlet 24, the next ball B is not paid out to the ascending member 51.

  In the next step S2, the control device 70 determines whether all the raising members 51 are raised. For this determination, detection by the position sensor 73 may be used, or an encoder may be attached to the electric motor 62 to measure the rotation speed. As shown in FIG. 10, when all the raising members 51 are raised, the control device 70 proceeds to step S <b> 3 and drives the arm 61 to operate the electric motor 62 to lower all the raising members 51. Then, the process proceeds to the next step S4. The cam 54 that has pushed up the roller 53 moves in the direction opposite to that when the roller 53 is raised, and the roller 53 is lowered by its own weight. Further, when the cam 54b is provided, the cam 54b comes into contact with and pushes down the roller 53 of the ascending member 51 that is not lowered due to its own weight due to problems such as catching. Thereby, the raising member 51 can be reliably lowered. On the other hand, when all the raising members 51 are not raised, the control device 70 skips step S3 and proceeds to step S4.

  In step S <b> 4, the control device 70 determines whether or not the ball B is detected by the ball sensor 71. If there is no detection signal from the ball sensor 71, the control device 70 returns to step S1 and repeats the processing of steps S1 to S4. For example, when the control device 70 operates the electric motor 62 to raise the raising member 51a, there is no ball B waiting on the raising member 51a, and the ball sensor 71 does not detect the ball B, The control device 70 operates the electric motor 62 so as to raise the raising member 51b. On the other hand, when the ball B is detected, the control device 70 ends the current process.

  According to the above processing, the balls B waiting in each of the plurality of introduction regions N1 to N3 surrounded by the partition member 40 and the rising member 51 can be sequentially introduced to the rail 30. Thereby, it is possible to hold the balls B in a plurality of rows and introduce the balls B in any row into the rail 30. Therefore, the storage unit 20 can be reduced in size and saved in space, and the degree of freedom of installation can be increased. Further, since the balls B in each row are individually introduced into the rail 30, the balls B can be introduced into the rail 30 without clogging at the time of introduction.

  The present invention is not limited to the above-described form and can be implemented in various forms. For example, in this embodiment, the ball supply device is described as applied to a game machine, but the present invention is not limited to this. You may use as an apparatus which supplies the ball | bowl used by ball games, such as baseball, golf, tennis, and table tennis. The balls stored in the storage unit can be sequentially introduced to the rails and sent out, and the balls can be supplied to any desired location. In the ball supply device according to the present embodiment, the example in which two ball supply units are provided has been described. However, the present invention is not limited thereto, and one ball supply unit and a drive mechanism may be provided. Further, a common driving mechanism may be provided to provide three or more ball supply units. Only the electric motor may be shared, and a plurality of arms may be provided to provide three or more ball supply units.

  In this embodiment, the example in which three rising members 51 are provided has been described, but the present invention is not limited to this. Any number of raising members may be installed. Accordingly, the number of partitions 22 in the storage member 21 may be increased or decreased. Further, the receiving region L1 may be larger than the entire region including the supply regions L2, L3, and L4 of the storage unit 20. For example, the receiving area L1 may be formed in a mortar shape. More balls can be stored. Any shape may be used as long as the storage member 21 is formed so as to be continuous with each of the plurality of rising members.

  The raising mechanism 50 raises each of the raising members 51 by the movement of the cam 54, but is not limited thereto. For example, a solenoid may be provided for each of the plurality of lifting members 51. Thereby, each of the several raising member 51 can be individually reciprocated. In this case, you may make the control apparatus 70 control each of the some raising member 51 independently. Further, although the arm 61 is driven by the electric motor 62 in order to cause the slider 55 to move along the rail 56, the present invention is not limited to this. For example, a drive mechanism such as a linear motor or a linear actuator may be used to drive the slider 55. Further, the sliders 55 and 55a may be individually moved by providing the drive mechanisms individually. Further, the ascending member 51 is provided so as to follow the cam 54 via the roller 53, but if a slippery member is used, it is not necessary to use a roller. Further, if the lifting member 51 has a structure and a member that easily falls due to its own weight, the cam 54a is provided directly below the lifting member 51 without providing the cam 54c, and the lifting member 51 directly contacts the cam 54a. It can also be.

  In this embodiment, when all the raising members 51 are raised, the arm 61 is driven and the slider 55 is moved in a direction in which the raising member 51 is lowered. The electric motor 62 may be operated so as to lower the raising member 51 every time. When the ball B is not detected, the electric motor 62 may be operated continuously so that the next raising member 51 rises. Further, when it is necessary to continuously supply the ball B, the electric motor 62 may be operated continuously. The order of raising and lowering of the raising member 51 may be set arbitrarily.
