Description

[Detailed description of the invention] related to motion equipment.

This type of rotary winning machine aims to diversify the game content and increase the entertainment level by giving variety to the winning device, and is an improved version of the old 1ml regular winning device. It is a further improved version of the tulip. In conventional rotary winning machines, a rotating body that has a large socket that easily accepts batted balls and a small socket that does not easily accept batted balls rotates in response to winning batted balls, but the rotation is 360 degrees. There is no object, and it only moves back and forth within a range of 90 degrees to 180 degrees.

The present invention provides a rotary drive device capable of continuous rotation of 360 degrees, which has not been possible with conventional technology, and thereby realizes an epoch-making rotary prize-winning machine with even more remarkable variability. be.

Conventional rotary drive devices include those that use solenoids,
Some utilized the attractive and repulsive forces of permanent magnets. For those that use a solenoid, a detector that detects the winning of a batted ball is connected to the solenoid in a post-like manner, and the solenoid is operated according to the winning of the batted ball, linking the direct expansion forward and backward movements of the solenoid's plunger. The rotor 11 was rotated through motion. The rotation angle given to this rotary body is limited to a maximum of 180 degrees, and the rotational motion must be a reciprocating motion, not to mention continuous rotation over 360 degrees. was technically impossible. In addition, since the rotating shaft is rotated through link motion, it is necessary to have a complex configuration of many small parts, which has the disadvantage of reducing manufacturing efficiency and easily causing failure. Since it inevitably intersects with the flow path of the winning batted ball, the flow path of the batted ball is restricted and it is inconvenient to eject the hit ball quickly.

In addition, as shown in FIGS. 1 and 2, in the case of using permanent magnets, a pair of permanent magnets 52 and 53 are buried in the back side of the rotating body 51 so as to have different magnetisms, and a pair of permanent magnets 52 and 53 are buried in the back side of the mounting board 54. By providing a rotary blade 56 that rotates back and forth 90 degrees when the winning batted ball 55 falls, and by arranging permanent magnets 57 and 58 with different magnetic pole arrangements t at the tips of the rotary blade 56, the landing of the hit ball is prevented. The rotating blade 56 is rotated to generate attraction and repulsion between the permanent magnets 52 and 53 of the rotating body 51, thereby driving the rotating body 51 to rotate.

For this reason, as in the case of using a solenoid, the rotation angle given to the rotating body is limited to about 180 degrees at most, and moreover, the rotational motion must be a reciprocating motion.
It was technically impossible to provide continuous rotation, let alone rotation of more than 360 degrees. In addition, since the structure is relatively complex, it reduces manufacturing efficiency and is prone to failure, and since winning batted balls are used temporarily, the ejection of batted balls becomes slower and speedier. There were some inconveniences in the progress of the game.

The present invention eliminates such drawbacks and inconveniences, and
A pair of permanent magnets is embedded in the back surface of the rotating body, and one of the electromagnets corresponding to each permanent magnet is installed close to each other, and by arbitrarily switching the current direction when energizing each electromagnet, the magnets can be To provide a rotary drive device for a rotary prize-winning player for a Nonochinko game, which can arbitrarily and continuously rotate a rotating body by 360 degrees or more by utilizing the attraction and repulsion force generated between the two poles.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on the drawings starting from FIG.

A rotating shaft 3 for pivotally supporting a rotating body 2 is implanted on the surface of a mounting board 1 to be attached to a game board so as not to protrude from the back surface of the mounting board 1.

On the periphery of the rotating body 2, a large socket 4 that easily receives a batted ball and a small socket 5 that does not easily accept a batted ball are disposed vertically facing each other, and a rotating shaft 3 is provided on the back surface of the rotating body 2. Shaft hole 6 that fits with
A permanent magnet 7 and a permanent magnet 8 having different magnetic properties are buried on the left and right sides of a horizontal line centering on the shaft hole 6 so as to slightly protrude toward the mounting board 1 side. For example, if the left permanent magnet 7 is the north pole, the right permanent magnet 8 is the south pole. Further, on the back surface of the rotating body 2, an engaging recess 9 is formed with the shaft hole 6 in the center.
to be drilled.

On the other hand, on the surface of the mounting board 1, when the large socket 4 and the small socket 5 of the rotating body 2 are located vertically upward, a prize opening 11 is drilled into which the winning batted ball 10 is introduced, and a winning hole 11 is formed on the left side of the rotating body 2. A fitting recess 12 into which the protrusions of the permanent magnet 7 and the right permanent magnet 8 fit.
, 13 are provided at the base of the rotating shaft 30, and a retaining convex portion 14 that fits with the four retaining parts 9 of the rotating body 2 is provided, and the rotating body 2 and the mounting board 1 are integrated by the fitting of the concave and convex portions. The rotating body is formed so as to stop rotating by 200 rotations. In this embodiment, the uneven portion is provided in a fan shape.

The rotating body 2 is fitted onto the rotating shaft 3 so as to be rotatable and slidable back and forth. The large socket 4 of the rotating body 2 consists of a pair of movable blades 15, and the movable blades 15 open left and right due to their own weight when the large socket 4 is located vertically upward, and conversely, when located vertically downward. In this case, the center of gravity of the tip of the movable blade 15 and the position of the movable shaft 16 are set so that it closes under its own weight. In addition, the large socket 4 does not necessarily have to be movable,
It is sufficient if the ball is formed so that it is easy for the ball to hit the mark. Further, the rotating body 2 is rotated left and right about the rotating shaft 3. By balancing the left and right sides of the rotating body 2, smooth rotation and reliable stopping can be achieved. By making the rotating body 2 as light as possible, using a shaft with a small diameter for the rotating shaft 3, and plating the surface of the shaft with chrome, rotational friction can be significantly reduced, and the rotating body can be driven with a correspondingly small magnetic force.

A holding frame 18 for holding a pair of electromagnets 1.7, ]7', which are the driving sources for the rotating assembly 2, is attached to the back surface of the mounting board 1. One electromagnet 17 has one magnetic pole 1 of the electromagnet 17.
9 is installed close to the right permanent magnet 7 of the rotating body 2, and the other electromagnet 17' is installed with one magnetic pole 19' of the electromagnet 17' close to the right permanent magnet 8 of the rotating body 2. Install. In this case, the magnetic poles of the electromagnet] 7, 17'] 9, ]
With respect to the horizontal edge passing through the center of the magnetic pole 20 surface of the corresponding permanent magnet 7.8, the center of the permanent magnet 7.
With respect to a perpendicular line passing through the center of the magnetic pole 20 surface of No. 8, the position is on the opposite side to the rotating shaft 3.

With this arrangement, the direction of rotation can be set arbitrarily, and a large rotational moment sufficient to continuously rotate the rotating body 2 over 360 degrees can be obtained.

That is, the polarity of the magnetic poles 20 of the permanent magnets 7 and 8 and the electromagnet 17
, 17' have the same polarity as the magnetic poles 19 and 19', the repulsive force of the same poles causes the permanent magnet 7.8 to repel in the direction of rotation, giving rotational force to the rotating body 2, and
Due to the rotation @3 of the rotating body 2, a rotational force is generated at the soft apogee, a large rotational moment is generated, and the rotation of the rotating body 2 is
can be rotated continuously.

According to the experimental results, the magnetic poles of the electromagnet] 7, 17'] 9
It is most effective to set the center of the angle 19' at a position of 45 degrees from the horizontal line passing through the center of the magnetic pole 20 surfaces of the permanent magnets 7 and 8, with the point where the horizontal line intersects with the vertical line as the center.

In the embodiment shown in the drawings, the rotating body 2 is installed to rotate clockwise. That is, for the left permanent magnet 7, the magnetic pole 19 of the electric magnet 17 is below the horizontal line passing through the center of the left permanent magnet 7, and below the vertical line passing through the center of the left permanent magnet 7. The magnetic pole 1 of the electromagnet 17' is arranged to be located on the opposite side of the rotating shaft 3, and the right permanent magnet 8 is located on the opposite side of the rotating shaft 3.
9' is above the horizontal M passing through the center of the right permanent magnet 8 and with respect to the vertical line passing through the center of the right permanent magnet 8,
It is arranged so as to be located on the opposite side of the rotating shaft 3.

This pair of electromagnets 17 and 17' are electromagnets 17 and 17.
By installing the axial direction of the ball 10 directly on the back surface of the mounting board 1, a flow path for the sludge and large hit balls 10 to the winning hole 11 is ensured.

Next, the effect will be explained.

As shown in Figure 3, when the small socket 5 of the rotating body 2 is located vertically north, the magnetic pole 19 of the corresponding electromagnet 17 is set to a different polarity (Nm) from the magnetic pole 20 (Nm) of the left permanent magnet 7. At the same time, set the magnetic pole 19' of the corresponding electromagnet 17' to a different polarity (N pole) from the magnetic pole 20 (Slli) of the right permanent magnet 8.
Then, the rotating body 2 is attached to the mounting board 1 using the attraction force due to the different polarities.
Suction to the side. The rotating body 2 slides backward by the suction force,
The engagement recess 9 of the rotating body 2 fits into the engagement protrusion 14 of the mounting board 1, and the left and right permanent magnets 7, 8 of the rotating body 2 also fit into the fitting openings 81512, 13 of the mounting board 1, The rotating body 2 is integrally engaged with the mounting board 1, and rotation in either the left or right directions is prevented and the rotating body 2 is reliably stopped.

Next, when the batted ball 10 lands in the small socket 4, the detector detects the winning of 100 batted balls, and a predetermined current is applied to the electromagnets 17, 17.
By energizing ', magnetic pole 1 of electromagnet 17°17'
9, 19' are the corresponding left and right permanent magnets 7,
8 magnetic! Make it the same pole as 20. This instantaneous rotating body 2 generates a clockwise rotational moment, but this is neutralized by the engagement between the engaging recess 9 and the engaging protrusion 14, so a repulsive force acts only in the direction of the rotating shaft 3. , the rotating body 2 momentarily moves forward on the rotating shaft 3. This movement occurs as a result of the rotating body 2 receiving an equal repulsive force from the two points of the left and right permanent magnets 7 and 8 with the rotating shaft 3 in the center. Due to the action of parallel movement, the shaft hole 6 and the rotating shaft 3 move extremely smoothly and quickly without being distorted.

By this movement, the engagement and fitting between the engagement recess 9 and the engagement recess 14 and between the left and right permanent magnets 7.8 and the fitting recess 12.13 are released. As a result, the rotating body 2 is able to detect the deviation between the center of the magnetic pole 19 of the electromagnet 17 located on the opposite side of the rotation direction and the center of the right permanent magnet 8 with respect to the horizontal line passing through the center of the left permanent magnet 7. The direction of rotation is determined by the offset between the center of the magnetic pole 19' of the electromagnet 17', which is placed on the opposite side to the rotation direction, with respect to the horizontal line passing through, and Since the center is located on the opposite side of the rotating shaft 3 with respect to the vertical Wii passing through the centers of the permanent magnets 7 and 8, a relatively large rotational moment is applied, and the rotating body 2 is rotated at the initially given rotation. It will rotate freely according to the moment.

Next, in order to stop the rotating body 2 in a desired state, the electromagnets 17 and 7' are connected so that the polarities of the left and right permanent magnets 7 and 8 and the polarities of the corresponding electromagnets 17 and 17' are different. Paper. That is, in order to position the large socket 4 vertically downward and to position the small socket 5, which is difficult to receive a batted ball, vertically north, so that it is possible to win a prize, set the polarity of the left electromagnet 17 to the S pole, and the polarity of the right electromagnet 17 to the S pole. The electromagnet 17' is the north pole. As a result, the permanent magnet 7 (N pole) of the rotating body 2 is connected to the left electromagnet 17 and the permanent magnet 8 (S: +
ff1) generates an attractive force due to different polarities between it and the right electromagnet 17', and braking is applied to the rotation of the rotating body 2, and the rotating body 2 is attracted to the mounting board 1 side and engages with the engagement recess 9. The moment the convex portion 14 coincides with the mounting board, it is integrally engaged with the mounting board and is securely stopped. On the other hand, in order to position the small socket 5 directly below and position the large socket 4, which easily receives the batted ball, above the vertical surface so that winnings can be made, the p\ property of the left electromagnet 17 should be set to N. The polarity of the right electromagnet 17' is the S pole. As a result, an attraction force due to water is generated between the permanent magnet 7 (Nu is the right electromagnet 17') of the rotating body 2 and the permanent magnet S (S pole) is the left electromagnet 17. '1li11tJJ is added to the rotation, and the rotating body 2 is attracted to the supplementary board 1 side, and the moment the engaging recess 9 and the engaging convex part 14 match, they are integrally engaged with the mounting board J and are surely stopped. In short, in the present invention, if the polarity of the electric motor 1, 7, and 7' is changed, the rotor 2 rotates 180 degrees and stops, but if the polarity is reversed again at the moment it stops, it rotates 360 degrees. Therefore, the rotational speed of the rotating body 2 and the stopped state of the rotating body 2 can be set by inputting desired data in advance into the computer that controls the energization of the electromagnets 17 and 17'. It is not only possible to simply rotate the rotating body 2 over 360 degrees continuously, but it is also possible to provide extremely diverse variations compared to conventional rotary winning machines.In addition, it is possible to provide not only the rotary winning machine but also other specific winning machines. It is also possible to easily rotate the rotary winning machine in response to the winning ball hitting the mouth.

Furthermore, electromagnets 1 are installed corresponding to the left and right permanent magnets 7 and 8, respectively.
7.17"e, the rotating body 2 can be moved back and forth on the rotating shaft 3 extremely smoothly and quickly by the attraction and repulsion of the magnetic force.

In this embodiment, the engaging protrusion 14 protruding from the mounting board 1 is provided with a slight shift (approximately 5 degrees) in the clockwise rotation direction. This is because the left and right permanent magnets 7, 8 and the corresponding electromagnets 1, 7, 17' are installed at different positions, so when the rotating body 2 is stopped, the engagement recess 9 of the rotating body 2 and the corresponding engagement Convex part 1
This is to compensate for the inclination in the direction opposite to the direction of rotation that occurs when the rotating body 2 exerts an attractive force between the permanent magnets 7, 8 and the electromagnets 17, ] 7' by an amount corresponding to a slight clearance between the magnets 4 and 4. be. As a result, the rotating body 2 is stopped vertically.

As shown above, the present invention employs a pair of electromagnets 17 and 17' as the entire driving source, and the magnetic pole 1 of the electromagnets 17 and 17'
By arranging the positions 9 and 1.9' in the above-mentioned specific state due to the relationship between the permanent magnets 7 and 8, it is possible to provide an extremely wide variety of rotating winning patterns, but the electromagnet as the rotational drive source ] 7, 17' must generate sufficient magnetic force to operate the rotation drive smoothly.

However, the power supply voltage generally used in electric pachinko machines is about 24V, and this voltage is used to drive various electrical components inside the machine, as well as the electromagnets] 7 , ] 7' need to be driven. However, since pachinko machines are required to be replaced every six months to a year, a difference in the power source used by a particular pachinko machine poses a major hindrance to replacing the pachinko machine.

However, in order to obtain the necessary magnetic force with a power supply voltage of about 24 V, the number of turns of the coil 21 of the electromagnet 17, 17' must be increased, and as a result, the number of turns of the coil 21 of the electromagnet 17, 17' must be increased.
The volume of the machine itself is so large that it becomes difficult to store it in the space on the back of the game board of the machine. Also, as the number of turns of the coil increases, the diameter of the electromagnets 1, 7, and 17' increases, and as a result, the magnetic poles 1 of the electromagnets 17 and 17' increase.
When 9.1g is placed correspondingly to the permanent magnets 7 and 8 on the back side of the rotating body 2, the winning hole 1 of the mounting board 1 and the winning batted ball 1
An inconvenience also occurs in that the flow path of 0 is restricted by the electromagnets 17, ] 7'.

Additionally, in general, the higher the frequency of operation of the electromagnets 17 and 17', the greater the amount of heat generated in the coil section, which reduces the magnetomotive force due to the heat generation. It has the disadvantage of causing deformation.

Due to the existence of such inconveniences and shortcomings, it is considered difficult to use an electromagnet as a driving source of a conventional rotary drive device, and as a result, there is no rotary drive device using an electromagnet.

Electromagnet 17 shown in the embodiment of the rotary drive device t according to the present invention
, 17' was devised exclusively for the rotary drive vI device for dick games in view of the construction circumstances and drawbacks.

That is, a magnetic force inducing inductor 23 made of a magnetic material such as iron is connected to one magnetic pole 22 of the electromagnet 17, ] 7',
The inductor 23 is connected to the other magnetic pole 1 of the electromagnet 17,] 7'.
9 and 19'. As a result, the self-electromagnet ] 7, 1 ? 9, 19'
By increasing the density of the lines of magnetic force between the magnetic poles 24 generated at the tip surface of the inductor 23, the volume of the electromagnet [7,]7' itself is reduced, and the size of the electromagnet 7' is reduced, and the magnetic force generated is increased.

Moreover, by forming the derivative 23 relatively widely,
In addition to being used as a heat dissipation plate for quickly dissipating the generated heat, the dielectric body 23 is formed linearly parallel to the axial direction of the electromagnet 17° and 17', so that it can be used as a fixing plate for the electromagnet 17. That is, rail grooves 25 that fit with both side portions of the induction body 23 are provided in the holding frame 18 that holds the electromagnets 7 and 17', and the induction body 23 is fixed by fitting into the rail groove 25, and the electromagnets 7 and 7 are fixed. 'A gap is provided between the main body and the holding frame 18, and this gap allows the generated heat to be quickly dissipated, and together with the heat dissipation effect of the inductor 23 itself, the heat is dissipated more efficiently, and the electromagnet 17 generated by the heat generation. ] This effectively prevents the weakening of the magnetic force of 7'. Further, deformation of the holding frame 18 due to heat can be avoided.

Moreover, in the rotary drive device according to the present invention, since two ``electromagnets'' 7 and 17' are used as one drive source, the volume of each piece can be reduced, and the inductor 23 is replaced by the electromagnet 17, 17'. In addition to being attached to one magnetic pole 22 of 7', each electromagnet] 7, ] 7'
Approximately 10 diameters (core diameter 3 holes, coil conductor wire diameter 00
7ψ), with a volume of 30 degrees in axial length, current is 400mA despite the power supply voltage being 24V.

The number of turns was 9500 times, and a magnetic force of 1100 Gauss was obtained.

This is approximately twice the magnetic force when the dielectric 23 is not used, and is sufficient to rotate the rotating body. In this case,
The dielectric 23 has a thickness of approximately 1 mm, a width of 10 mm, and a length of 30 mm.

Moreover, due to such miniaturization, as shown in the drawings of the embodiment,
It has become possible to attach the electromagnets 17, ] 7' to the back surface of the mounting board 1 without restricting the flow path of the batted ball 10 flowing into the winning hole 11.

In other words, the present invention includes a pair of permanent magnets 7 having different polarities on the back surface of a rotating body 2 rotatably installed on a mounting board 1.
. With respect to the horizontal leg passing through the center of the magnetic pole 20 surface of 7.8, set the rotating body 2 at a position opposite to the direction of rotation in which it is intended to rotate, and with respect to the vertical line passing through the center of the magnetic pole 20 surface of the permanent magnets 7 and 8. Since it is arranged so that it is in the opposite position to the rotating shaft 3, by appropriately switching the current direction of the electromagnet, it is possible to give the rotating body 2 4 consecutive rotations of 360 degrees or more, and it is possible to rotate the rotating body 2. It is possible to give a variety of interesting variations to the occasion.
