Description

  The present invention relates to a ball throwing apparatus used for practicing ball games, particularly table tennis, tennis, soccer, volleyball and the like.

  Various pitching devices for practicing ball games such as table tennis and baseball have been proposed. Many of these ball-feeding devices use one roller or a pair of upper and lower rollers. A ball guided by a ball supply device is sandwiched between the ball-feeding devices and the ball is fed using the rotational force of the rollers. Then, by changing the rotation speed of the roller, the pitching speed and the spin strength can be changed. And it is comprised so that the ball | bowl of various rotation can be discharged by rotating a launch cylinder to the surroundings of the axis line (for example, refer patent document 1, 2).

  Also, an apparatus has been invented and devised that has three or more rotating rollers and sends various rotating balls mixed with non-rotating balls and horizontal and oblique rotations by controlling the rotation of each roller ( For example, see Patent Documents 3 and 4 and Non-Patent Document 1).

  For example, in the practice for table tennis, a piston mechanism is used as a ball supply device for feeding balls one by one (see, for example, Patent Documents 5 and 6). As shown in FIG. 14, the piston 103 is moved to the ball launching portion along with the movement of the swing arm 102 (arrow b in FIG. 14) that swings back and forth by rotating the disk 101 (arrow a in FIG. 14). Balls in the ball stocker 106 are rotated by rotating the stirring rod 105 in conjunction with the disk 101 through a drive mechanism that moves back and forth (arrow c in FIG. 14), the longitudinal axis 105a, and the gear 105b. A stirring mechanism 105, 105a, 105b for preventing the clogging of the ball, and a spring 107 that holds the ping-pong ball in its position so that it does not move unexpectedly to the front ball outlet, such as when the ball launcher is tilted downward, 108 is provided.

Japanese Patent Publication No. 5-82225 JP 09-262331 A Japanese Utility Model Publication No. 61-14074 JP-A 62-27975 Yasumori Ide, “Production of a Ball-Moving Robot” Power Company 2001 Japanese Utility Model Publication No. 62-177758 Japanese Utility Model Publication No. 4-117672

  By the way, in the ball throwing apparatus having a structure having only one roller or only one set of upper and lower parts, the rotation direction given to the ball can only give a rotational force that is always perpendicular to the rotation axis of the roller. Therefore, even if a simple change ball, such as a curve ball or a cut ball, can be sent, a non-rotation ball or a subtle change ball in which horizontal and oblique rotations are mixed cannot be realized. In addition, in order to fire a horizontally or obliquely rotated ball, the ball launcher must be rotated around its axis each time, and the operation is complicated when continuously sending arbitrary changing balls. There is a problem that it takes time, or the structure of the apparatus becomes complicated.

  Also, in a ball-feeding device having three or more rollers, by controlling the rotation of each roller, a non-rotating ball or a slightly rotating ball mixed with lateral rotation and diagonal rotation can be used to move the ball launcher around its axis. However, it is inconvenient to control the rotation of each roller, and the operation method is not ideal.

  FIG. 13 shows an example of a ball rotation control method in the case of using three rollers independently driven by the motors M1, M2, and M3. In FIG. 13, the direction and length of the white arrow indicate the direction and size of rotation of the ball B as viewed from the opposite side of the firing direction axis, and the direction and length of the normal arrow indicate the direction of rotation of the roller. This indicates the magnitude of the rotational speed, and when the arrow is not displayed, it indicates that the roller has stopped. + In parentheses indicates the rotation direction of the roller clockwise (forward rotation),-indicates counterclockwise rotation (reverse rotation), and 0 indicates stop. The three symbols in parentheses indicate the rotational directions of the rollers R1, R2, and R3 in order from the left.

  When the three rotation states of the three rollers R1, R2, and R3 are controlled to be forward rotation, reverse rotation, and stop, there are 27 states in total, but the rotation control state in which the ball B can be actually emitted forward is illustrated. It was shown in FIG. In this case, the rotation control states of the left rotation, the lower left rotation, and the right rotation and the lower right rotation in FIG. 13 are not controlled by forward / reverse rotation and stop of the roller, but are controlled by the rotational speed of the roller R2, respectively. State. In FIG. 13, the rotation control states of the rollers R1, R2, and R3 are represented by forward rotation +, reverse rotation −, and stop 0 in parentheses for these ten spins. The operation becomes complicated, and the operation becomes complicated when the ball type is continuously changed to send a ball, which is not practical.

  On the other hand, in the ball supply device having the piston mechanism, a spring for preventing the ball from unexpectedly moving to the front ball launcher, or a ball in the ball stocker is at the entrance of the vertical guide path led to the ball supply device. It has a stirring means via a gear for preventing clogging, and the structure is complicated.

Many of the conventional table tennis pitching devices are either fixed to the end line of the table tennis table or installed at the rear, making it difficult to pitch to the vicinity of the net, and a short range of multiple types of balls. In other words, there is a problem that the practice of receiving practice on the net and the front-end practice effect cannot be obtained.
In addition, there are problems that beginners, elderly people, and infants are not easy to use, such as high throwing speed, excessive spin, difficulty in understanding the timing of ball launch, and large and heavy equipment.

  The present invention has been made in view of the above circumstances, and is configured so that balls of various types of balls having different rotational speeds and firing speeds can be continuously fired, and includes a non-rotating and a plurality of rotational direction setting operation units. An object of the present invention is to provide a ball pitching device having a ball type selection means and improving practical practice effects and operability, and capable of practicing according to the technical level from beginners to advanced players.

  The constitutional feature of the present invention for solving the above-described problem is that three or more rollers are arranged around the firing direction axis, and the roller peripheral surface is substantially the same as the ball spherical surface at the same time at the equivalence point of the ball circle. A ball launching device for imparting an initial firing speed, a rotational direction and an initial rotational speed synthesized to the ball by rotating contact, a roller driving means for independently rotating the rollers, and a ball stacker to guide the ball, A ball pitching device comprising a ball supply device for continuously pushing out one by one to the inner space of each roller arrangement, and a ball type control means for controlling the number of rotations including forward and reverse rotation directions of each roller It is in having.

  The ball pitching device includes a ball type selection unit including a non-rotation setting operation unit for the ball and a plurality of rotation direction setting operation units for making the rotation directions of the balls different from each other.

  In the ball type selection means, each rotation direction setting operation unit surrounds the non-rotation setting operation unit as a center, and the position of each rotation direction setting operation unit with respect to the position of the non-rotation setting operation unit The rotation direction of the ball is associated with the direction substantially the same as the relative direction.

  According to the above-described configuration, the ball type control means is provided that can set the ball type by controlling the rotation of the three rollers so that the ball is rotated in the same direction as the direction input from the ball type selection means. Therefore, the visibility is good and the selection of the ball type is simple, and the usability of the ball throwing device of the present invention is improved.

  According to a fourth aspect of the present invention, there is provided a ball throwing device according to any one of the first to third aspects, wherein the ball supply device uses a swing slider crank mechanism, and the swing slider link has the lower end. The ball stacker guides the ball from the ball stacker to fall to the lower end side while the side is separated from the inner space portion, and pushes the ball to the inner space portion while the lower end side approaches the inner space portion. Yes.

  According to the above configuration, the swinging slider link continuously swings back and forth, whereby the ball is guided to drop from the ball stacker to the lower end side of the swinging slider link and is continuously fired from the ball launching device. The Further, the swing slider link becomes a conduction path for guiding the ball from the ball stacker to the lower end of the swing slider link, thereby simplifying and miniaturizing the entire ball launcher.

  According to a fourth aspect of the present invention, the swing slider link has a swing member that moves a ball in the ball stacker on an upper end side thereof.

  According to the above configuration, the swing slider link swings, and the swing member on the upper end side swings the ball in the ball stacker to prevent clogging of the ball in the ball stacker. The ball launcher as a whole can be simplified and miniaturized without separately providing ball agitating means or rocking means in the ball stacker.

  Further, in the fourth or fifth aspect, the ball type control means controls the rotational speed of the crank of the swing slider crank mechanism.

  According to the above configuration, by controlling the rotation speed of the crank of the swing slider crank mechanism, it becomes possible to adjust the forward / backward swing speed of the lower end side of the swing slider link, and the ball firing interval can be arbitrarily set. Since it can be changed and controlled in synchronization with the above-mentioned ball type selection means, various kinds of changing balls can be launched at arbitrary intervals, so that the quality of practice content is improved.

An example of the ball throwing device of the present invention will be described taking a table tennis ball throwing device as an example.
As shown in FIG. 1, an overview of the ball launcher 11 of the present invention is as follows. The ball launcher 30 includes three rollers R1, R2, and R3 that are independently driven to rotate. The ball supply device 20 having a swing slider crank mechanism for pushing out the ball, the number of rotations including the forward and reverse rotation directions of the three rollers R1, R2, and R3, and the crank 23 of the swing slider crank mechanism It is comprised from the control apparatus 40 which has the spherical type control means which controls the rotation speed of this.

  The ball supply device 20 has a swing slider crank mechanism. When the crank 23 rotates, the swing slider link 25 swings, and a swing member provided on the upper end side of the ball supply device 20 is a ball B in the ball stacker BS. And the ball B from the ball stacker BS is guided to drop to the lower end side in a state where the lower end side is separated from the hollow portion. Further, when the crank 23 is rotated, the ball B is pushed out into the hollow part and fired from the ball launcher 30 in the process in which the lower end side approaches the hollow part.

  In the ball launcher 30, three rollers are arranged around the launch direction axis, and the launch is combined with the ball B by rotating and contacting the roller circumferential surface with the ball spherical surface almost simultaneously at the three equal points of the ball circle. By providing the initial speed, the rotation direction, and the initial rotation speed, the ball type and the flight distance of the ball B are determined. The rollers R1, R2, and R3 are driven by motors M1, M2, and M3, and each of them is independently rotationally controlled by a ball type control means, and has a structure in which there is only one roller or only one upper and lower pair. As described above, the ball can be sent continuously in various rotations including non-rotation without rotating the launch tube around its launch axis.

  On the operation panel 41 of the control device 40, a ball type including a ball non-rotation setting operation unit 43e and a plurality of rotation direction setting operation units 43a to 43d and 43f to i for making the rotation directions of the balls different from each other. Selection means 43 is provided. The ball type selecting means 43 is a front view when viewed from the opposite side of the firing direction axis, and the rotation direction setting operation units 43a to 43d and 43f to i are centered on the non-rotation setting operation unit 43e. The ball type selecting means 43 is arranged in the same direction as the relative direction of the positions of the rotation direction setting operation parts 43a to d and 43f to i with respect to the position of the non-rotation setting operation part 43e. The rotation directions of the balls are associated with each other.

  In the conventional digital control method such as forward / reverse rotation and stop of the three motors by switching the switch, the ball type setting operation is complicated and impractical, but by including the ball type selection means 43 of the present invention, The ball type can be easily set and the visibility and operability are improved.

  The conventional table tennis ball throwing device is configured to be used by being fixed to the center of the rear portion of the table tennis table. However, as shown in FIG. 2, the ball pitching device 10 of the present invention is placed anywhere on the table tennis table. Can be sent. The ball type, length, and firing interval of the ball B are set on the operation panel 41, so that practice closer to the actual battle than receive, rally, etc., or practice according to the skill level from beginner to advanced can be performed.

  Hereinafter, the configuration of the ball throwing device 10 will be described in detail with reference to the drawings. 1 is an overall configuration of a ball throwing device 10 according to one embodiment of the present invention, FIG. 3 is a front view, FIG. 4 is a side view, FIG. 5 is a detailed perspective view of a ball supply device 20, and FIG. FIG. 11 shows an operation panel 41 of the control device 40. FIG.

As shown in FIG. 4, the substrate 13 is attached to the end of the substrate 11 at an inclination, a ball launch port 31 is provided near the center of the substrate 13, and a launching device 30 is provided on the outer surface of the substrate 13. Is provided. Immediately below the ball launch port 31 of the substrate 13, the substrate 12 is fixed in a state orthogonal to the substrate 13 on the opposite surface where the launching device 30 is provided, and the other end is in contact with the substrate 11. It is fixed where it is. A ball supply device 20 is provided on the substrate 12. Further, a substrate 14 provided with a control device 40 is fixed to the other end of the substrate 11. The substrate 15 has a hole for supplying the ball B from the ball stacker BS to the ball supply device 20.
However, the configuration and arrangement of the device and the substrate are not limited to those described above.

Next, the ball supply device 20 will be described based on FIGS. 4, 5, 6, 7, 8, and 9.
As shown in FIGS. 4 and 5, the ball supply device 20 provided on the substrate 12 is provided with a swing slider crank mechanism, and when the crank 23 rotates, the side plates 26 a and 26 b installed up and down. The slider 21 moves back and forth along the slider guide 21b formed in the above to push the ball into the inner space of the three roller arrangement. The slider 21 is connected by a connecting rod 22 and a connecting rod pin 22a near the center thereof, and the connecting rod 22 is connected by a crank 23 and a crank pin 23a fixed to a ball supply motor M4.

  The slider 21 is connected to both ends of the slider 21 through a pair of swinging slider links 25 and a long hole 25a formed at the lower end thereof via a slider pin 21a. And the upper end side of a pair of rocking slider link 25 is connected with the support | pillar 24 and the support | pillar pin 24a. Further, an oscillating rod 25b and a drop position restricting means 25c are provided as oscillating members at the upper end of the oscillating slider link 25. These oscillating slider links 25 oscillate the balls in the ball stacker BS. B is swung to prevent clogging.

  Therefore, when the swing slider link 25 swings in conjunction with the swing slider crank mechanism described above, the ball B in the ball stocker BS swings and is guided and dropped to the lower end side of the swing slider link 25 by its own weight, and moves back and forth. The slider 21 is pushed out into the inner space of the three roller arrangement and is continuously supplied to the ball launcher 30 one by one.

  6, 7, 8, and 9 show the state of the ball B with respect to the rotation state of the crank 23 in the above-described swing slider crank mechanism. However, the side plates 26a and 26b are omitted for easy understanding of the state of the ball.

  As shown in FIG. 6, the crank 23 rotates and its rotation end reaches the dead point (dead point A) farthest from the inner space, and the rotation end is the standby position detection switch SW1. When is pressed, the ball supply motor M4 starts to rotate in the direction of the arrow at a preset number of rotations, and the slider 21 starts to approach the inner space, and the ball B starts to move to the inner space.

  In the back plate 27, the weight of the waiting ball BB is applied to the ball B at the lower end of the swing slider link 25 from the side (a two-dot chain arrow), so that the ball B unexpectedly moves to the inner space. It is to prevent it from doing.

  FIG. 7 shows a state in which the crank 23 rotates, the slider 21 comes closest to the inner space, and the rotation end of the crank 23 reaches the other dead center (dead point B). The ball B pushed out to the inner space by the slider 21 is given the initial firing speed, rotational direction, and initial rotational speed synthesized by rotating contact with the three rotating rollers R1, R2, R3. , And fired from the ball launch port 31. At that time, the waiting ball BB rolls onto the connecting rod 22. The ball BB is held on the connecting rod by a pair of left and right side plates 26a, 26b and a back plate 27.

  The crank 23 is lit while the turning end of the feed position detection switch SW2 is being pressed to inform the practitioner when the ball B is fired from the ball launch port 31, and a firing lamp 32 is provided so that the timing can be easily taken. It is equipped.

  Subsequently, the crank 23 rotates in the direction of the arrow, and as shown in FIG. 8, the connecting rod 22 is pulled up with the connecting rod pin 21a as a fulcrum, and the slider 21 starts to move away from the inner space, and the connecting rod 22 The waiting ball BB rolls down on the substrate 12.

  At this time, as shown in FIG. 9, the ball B is controlled by the back plate 27 so as not to receive the force toward the inner space from the waiting ball BB (two-dot chain line in FIG. 6). Since the substrate 12 on which the ball supply device 20 is installed is inclined, the ball B does not move to the inner space 31, the slider 21 moves away from the inner space and the ball B also moves in the direction of the arrow. .

  Further, when the crank 23 rotates and reaches the dead point A, and the rotation end of the crank 23 pushes the standby position detection switch SW1, one cycle is completed. During this time, the rocking slider link 25 is swung in conjunction with the back and forth movement of the slider 21 of the rocking slider crank mechanism, and the rocker rod 25b and the drop position control means 25c installed on the upper end side of the rocker slider link 25 are moved into the stacker BS. The ball B is swung to supply the ball B to the ball supply device 20.

  FIG. 3 shows a front view of the ball launcher. The ball launcher 30 will be described based on FIG.

  In the vicinity of the center of the substrate 13, a ball launch port 31 having a diameter slightly larger than that of the ball B, with the launch direction axis of the ball B as the center, is opened. On the surface of the substrate 13 opposite to the ball supply device 20, three rollers R1, R2, and R3 are arranged at equiangular intervals around the firing direction axis, that is, at intervals of 120 degrees, and three on the spherical surface of the ball B. The roller peripheral surfaces are arranged so that they can rotate and contact evenly at substantially the same time. Motors M1, M2, and M3 are attached to the rollers R1, R2, and R3 as roller driving means that independently rotate and control the rotational speed of each roller including forward and reverse rotation directions and stopping. Yes.

  The ball B pushed out by the slider 21 of the ball supply device 20 into the inner space of the three roller arrangement is rotated in contact with the three roller peripheral surfaces and synthesized with the ball B. It is configured to give an initial velocity and send various ball types.

  When the ball 21 is fired when the slider 21 comes closest to the inner space, the substrate 13 is lit while the delivery position detection switch SW2 is pushed by the rotating end of the crank 23. A firing lamp 32 is provided to notify when B is fired. The firing lamp 32 can be installed anywhere as long as it is visible to the practitioner.

  In addition, a separate display device may be provided on the substrate 13 so that the ball type information to be launched can be seen by the practitioner.

  As shown in FIG. 1, a control device 40 having an operation panel 41 is provided at the rear portion of the apparatus main body 10. FIG. 10 shows a control block of the control device 40. The control device 40 will be described based on FIG.

As shown in FIG. 10, information is input / output between the control device 40 and the operation panel 41.
Based on the information input from the operation panel 41, the three motors M1, M2, and M3 of the ball launcher 30 and the ball of the ball supply device 20 from the control device 40 via the drive units DU1, DU2, DU3, and DU4. Output control is performed for the rotational speed of the supply motor M4 including forward and reverse rotation directions and stopping. Also, the control device 40 can output and display the ball type input from the operation panel 41 on the operation panel 41.

  Detection information of the standby position detection switch SW1 and the delivery position detection switch SW2 is input to the control device 40. When detection information indicating that the ball is pushed out from the ball supply device 20 by the slider 21 and the delivery position detection switch SW2 is pushed by the rotation end of the crank 23 is input to the control device, a signal is output to the launch lamp 32 that informs the launch. It has come to be. When the crank 23 further rotates and the rotation end of the crank 23 is pushed by the standby position detection switch SW1, detection information is input to the control device 40 to notify that the crank 23 has made one rotation.

  The operation panel 41 will be described with reference to FIG. FIG. 11 shows an overview of the operation panel 41. The operation panel 41 turns on / off the lighting of the ball type selection means 43, the fine adjustment unit 44, the power switch 50 for turning on / off the entire ball-sending device 10, the power lamp 51, and the firing lamp 32 of the ball launching unit 30. It consists of a fire lamp switch 52, a stop button 53, and a fire button 54.

  The ball type selection means 43 will be described. The ball type selection means 43 includes a ball type selection means 43 including a ball non-rotation setting operation portion 43e and a plurality of rotation direction setting operation portions 43a to 43d and 43f to i for making the rotation directions of the balls different from each other. It is comprised from the operation parts 43j-k which control.

  The ball type selection means 43 is a front view when viewed from the opposite side of the firing direction axis, and the rotation direction setting operation units 43a to 43d and 43f to i are centered on the non-rotation setting operation unit 43e. Arranged in eight directions, upper left, upper, upper right, left, right, lower left, lower, and lower right, respectively, and the relative rotation direction setting operation units 43a to 43d and 43f to 43i from the non-rotation setting operation unit 43e. The direction and the rotation direction of the ball are arranged so as to correspond to each other. Each of the rotation direction setting operation units 43a to 43d, 43f to 43i is displayed with an arrow indicating the rotation direction, and it is easy to select a ball type visually, thereby improving operability. .

  FIG. 13 shows the relationship between the rotation direction of the ball B, that is, the ball type and the rotation control state of the rollers R1, R2, and R3. The nine types of ball types in the frame are arranged according to the non-rotation setting operation unit and each rotation. It is shown so as to correspond to the arrangement of nine ball types assigned to the direction setting operation units 43a to 43i. When an arbitrary ball type is selected by the ball type selection means 43, as shown in FIG. 13, the rotation direction of the ball, that is, the rotation type of the ball type and the rollers R1, R2, R3 is analyzed, and the motors M1, M2 are analyzed. , M3 rotation direction is set.

  Further, each time the speed-lowering button 43j or the speed-up button 43l is pressed, the rotation of the rollers R1, R2, R3 is maintained while maintaining the rotation control state of the individual rollers R1, R2, R3 in the selected ball type. The number can be decreased or increased by 10% to 50% to weaken or increase the spin of the ball, or the length of the flying distance can be adjusted depending on the rotation state of the roller.

  However, the value of the rate of increase / decrease in the number of rotations of 10% up to 50% is affected by various conditions such as the performance of the motor and is not limited to this value and can be changed as appropriate.

Furthermore, when the same ball type as the selected ball type is selected, the same effect as when the speed-up button 43l is pressed is obtained, but there is a rotation control state of the roller that applies a stronger spin to the ball. In addition, when the lower left and lower right rotation ball types are selected, the rotation control state of the rollers R1, R2, and R3 is such that the rotation direction of the stopped rollers further increases the spin of the ball. Rotation is set in the direction. For example, in FIG. 13, the rotation control states of the upper, lower left, and lower right rotations shift to the new rotation control states of upper 2, lower left 2, and lower right two rotations shown outside the frame, respectively, and then rollers R1, R2, and R3 The number of revolutions increases.
The initialization button 43k is set so as to return to the initial setting value of the currently selected ball type.

  The fine adjustment unit 44 analyzes the rotation control state of the rollers R1, R2, and R3 based on the ball type selected by the ball type selection unit 43, and the rotation directions of the motors M1, M2, and M3 are changed as shown in FIG. Simultaneously with the setting, the lamps 44aa, 44bb, 44cc of the motors for which the rotation has been set are turned on. The rotation speeds of the preset motors M1, M2, and M3 can be individually adjusted by the volumes 44a, 44b, and 44c, respectively, and all rotations are generated based on the nine types of ball types by the ball type selection means 43. It is possible. Further, the pitching interval of the balls B can be arbitrarily changed by adjusting the rotation speed of the motor M4 with the volume 44d.

  For example, when the lower left rotation direction setting operation unit 43g is pressed, the rotation directions of the motors M1, M2, and M3 are set to forward rotation, forward rotation, and stop (++ 0), respectively, but the lamp 44aa is lit and 44bb is lit. 44cc is turned off, notifying that the rotation is controlled, and notifying that the rotation speeds of the motors M1, M2 can be controlled by the corresponding volumes 44a, 44b of the fine adjustment unit 44. Here, when the volume 44a is adjusted to gradually reduce the rotation speed, the ball type gradually changes from the lower left rotation to the lower rotation. In addition, when the rotation of the volume 44b is gradually reduced in the control state of the lower left rotation, the ball rotation gradually changes from the lower left rotation to the left rotation, and the ball type changes from left rotation to left rotation. A subtle change can be given to the rotation selected by the seed selection means 43, and the practice content can be improved.

 Subsequently, when the ball type is changed, it is only necessary to press any non-rotation and each rotation direction setting operation unit 43a to 43i once. For example, when the lower left rotation direction setting operation unit 43g is pressed by the operator, the “lower left arrow” and the lamps 44aa and 44bb of the motors M1 and M2 are lit in the ball type display window 45m, and the motors M1 and M2 and the ball supply motor M4 are turned on. Rotates in the rotation control state (++ 0) and the number of rotations set in advance for each ball type, and the ball in the lower left rotation is fired.

Any input means suitable for the purpose of the present invention, such as a numeric keypad, an omnidirectional key, a joystick, a trackball, and an analog stick, can be used as the ball type selection means.
In the above-described example, the operation panel 41 is attached to the rear part of the ball launcher main body. However, the operation panel 41 is separated from the apparatus main body by means of separately providing a wireless device or extending a connection cord with the main body, for example, practice. It is good also as a structure which puts an operation panel in the hand of a person.

  FIG. 12 is an operation flowchart showing the relationship between various processing tasks. The operation of the ball throwing device 10 will be described with reference to FIG.

  When the power is turned on, the activation process task 61 is executed, and then the ball type setting process task 63, the firing process task 65, and the stop process task 66 can be executed. The abnormality processing task 62 can be executed simultaneously with power-on, and can be executed by an abnormality processing instruction.

  In the activation processing task 61, the ball supply device 20 is initialized when the power is turned on. The ball supply motor M4 is driven until the rotational end of the crank 23 reaches the dead point (dead point A) at the position farthest away from the inner space of the three rollers, and the standby position is detected by the rotational end. The switch SW1 is pressed and the power lamp 51 is lit. Thereafter, the default values of the launch specification data of the ball type, distance, and interval are output. For example, the ball type is initially set to knuckle, the flight distance is long, and the pitching interval is short.

  In the abnormality processing task 62, when an abnormality occurs in this apparatus, the abnormality is detected by the control apparatus 40, the power lamp 51 is blinked, and the ball supply apparatus 20 and the ball launching apparatus 30 are stopped.

  In the ball type setting processing task 63, when the non-rotation of the ball type selection unit 43 of the operation panel 41 and each rotation direction setting operation unit 43a to 43i are pressed, the selected ball type is displayed in the ball type display window 45m. The ball type data processing task 64 is activated.

  In the ball type data processing task 64, the rotation direction of the ball and the rotation control state of the rollers R1, R2, and R3 are analyzed according to the input ball type as shown in FIG. 13, and the rotation direction of the motors M1, M2, and M3 and The rotational speed is set and driven.

  For example, when the right rotation direction setting operation unit 43f is pressed, the ball type data processing task 64 is activated, and the motors M1, M2, and M3 are in the rotation control state (0 + −), that is, the rotation of the motor M1 is stopped and the motor M2 is normal. The rotation control data for rotation and reverse rotation of the motor M3 is set, and rotation is started at a preset rotation speed.

  In the firing processing task 65, when the firing button 54 is pressed, the ball supply motor M 4 of the ball supply device 20 is driven as shown in FIG. 6, the crank 23 rotates, and the lower end of the swing slider link 25 is moved. In the process in which the attached slider 21 approaches the inner space of the roller arrangement, the ball B is pushed out to the inner space. At this time, while the delivery position detection switch SW2 is being pushed by the rotating end of the crank 23, the firing lamp 32 is lit and the firing timing is recognized. Further, the ball supply motor M4 is driven until the crank 23 rotates and rotates to the dead point A. When the rotation end of the crank 23 presses the standby position detection switch SW1 at the dead point A, detection information is output and the end of one cycle is output.

  In the stop processing task 66, when the stop button 53 is pressed, the crank 23 of the ball supply device 20 rotates to the standby position of the dead point A, and when the standby position detection switch SW1 is pressed, the ball supply motor M4 is stopped. Thereafter, the rotations of the motors M1, M2, and M3 of the ball launcher 30 are stopped.
