Description

  The present invention relates to a reel rotation mechanism.

  In a reel-type gaming machine, when the looseness of the reel becomes large, the reel may shake at the start and stop of the reel.

  Various techniques are known as techniques related to such background (see, for example, Patent Document 1).

  For example, Patent Document 1 describes a motor drive device in which a pressing portion presses a reel toward a wall portion. More specifically, the motor drive device includes a rotary shaft support for rotatably supporting the reel, and a wall is formed at one end of the rotary shaft support in a direction perpendicular to the longitudinal direction of the rotary shaft support. And a pressing unit configured to press a reel rotatably supported by the other end of the rotation shaft support toward the wall. In this manner, depending on the motor drive device, it is possible to suppress surface fluctuation of the reel at the start and stop of the reel.

  When stopping the motor to stop the reel, if the rotational inertia of the reel is larger than the hold torque of the motor, the excitation phase of the motor may be shifted. Such deviation is called motor step out and causes the motor to be unable to rotate normally since the phases of the motor do not match at the start of the next rotation of the reel.

  An object of the present invention is to provide a reel rotation mechanism that solves the problems described above.

According to a first aspect of the present invention, a reel gear to which torque is transmitted from a motor generating torque, an absorber whose one end is connected to the reel gear, and the other end of the absorber are linked so that torque is received from the reel gear through the absorber. A reel gear cap which is transmitted and rotates around the rotation center of the reel gear, and the reel gear cap and the reel gear are connected, and relative rotation of the reel gear cap with respect to the reel gear centering on the rotation center is within a constant angle range. The connecting mechanism is a reel rotating mechanism including a hole formed in the reel gear and a claw formed in the reel gear cap .

  Note that the above summary of the invention does not enumerate all the necessary features of the present invention. In addition, a subcombination of these feature groups can also be an invention.

  As apparent from the above description, the reel rotation mechanism of the present invention is less likely to cause motor step-out and can reduce the bound stop phenomenon.

FIG. 4 is a longitudinal sectional view of the reel rotation mechanism 100. As shown in FIG.
The motor 14 shown in FIG. 4 is a power source that generates a rotational force for rotating the reel gear 11. A pinion 16 engaged with the flat teeth 11 a of the reel gear 11 is fixed to the motor 14 of the present embodiment. The motor 14 according to the present embodiment may be, for example, a PM motor which is one of inexpensive induction motors. The configuration of the motor 14 is not particularly limited, but may be a stepping motor that can be stopped at each predetermined rotation angle corresponding to the configuration of the reel unit 64. The motor 14 is electrically connected to a control circuit (not shown), and the rotation state is controlled by the control circuit.

  As shown in FIG. 5, the reel rotation mechanism 100 includes a reel gear 11, a torsion coil spring 12, and a reel gear cap 13.

  The reel gear 11 is an annular member to which rotational force is transmitted from the pinion 16 of the motor 14. The reel gear 11 has flat teeth 11a, a disc portion 11b, a hole portion 11c, a cylindrical portion 11d, a first spring engagement hole 11e, and a shaft insertion hole 11f.

  The flat teeth 11 a are teeth formed on the outer peripheral portion of the disc portion 11 b and engaged with a pinion 16 described later attached to the motor 14.

  The disk portion 11 b is a plate-like portion having a disk shape whose center line is the rotation center of the reel gear 11.

  The hole portion 11c is a portion formed at an interval of 180 degrees in the circumferential direction of the disc portion 11b and in which two through holes penetrating the disc portion 11b are formed. The hole portion 11c is disposed in the inner region of the flat teeth 11a formed on the outer periphery of the disc portion 11b. A first abutment portion 11g and a second abutment portion 11h are respectively formed in the two two through holes of the hole portion 11c.

  The first abutment portion 11 g restricts the rotation of the reel gear cap 13 with respect to the reel gear 11 by the contact of the claw portion 13 d of the reel gear cap 13. The second abutment portion 11 h restricts the rotation of the reel gear cap 13 with respect to the reel gear 11 when the claw portion 13 d of the reel gear cap 13 of the reel gear cap 13 abuts.

  The distance between the first butting portion 11g and the second butting portion 11h is larger than the claw portion 13d of the reel gear cap 13 in the circumferential direction of the disc portion 11b. Therefore, the hole 11c allows rotation of the reel gear cap 13 with respect to the reel gear 11 due to movement of the claws 13d of the reel gear cap 13 in the hole 11c within a predetermined range, and this predetermined range is Regulate the rotation beyond.

  The cylindrical portion 11d has a cylindrical shape having a shaft insertion hole 11f and is formed at the central portion of the disc portion 11b. The pivot shaft 18 is inserted into the shaft insertion hole 11f of the cylindrical portion 11d.

  The first spring engagement hole 11 e is a portion in which a hole for engaging a reel gear engagement projection 12 b described later of the torsion coil spring 12 is formed. In the present embodiment, the first spring locking holes 11 e are formed at a plurality of positions separated in the circumferential direction of the disc portion 11 b. Although it is not essential that the plurality of first spring locking holes 11e are formed in the disk portion 11b, the plurality of first spring locking holes 11e are formed in the disk portion 11b, so that the torsion coil is formed. In order to reduce the influence of the spring characteristic due to the individual difference of the spring 12, one hole can be selected and used from the plurality of first spring locking holes 11e.

  The torsion coil spring 12 is an example of an absorber that connects the reel gear 11 and the reel gear cap 13 and buffers rotational torque between the reel gear 11 and the reel gear cap 13. The torsion coil spring 12 includes a spring main body 12a having a predetermined spring constant, a reel gear locking projection 12b disposed at an end of the spring main body 12a on the reel gear 11 side, and a spring main body 12a on the reel gear cap 13 side. And a reel gear cap locking projection 12c disposed at an end. In the present embodiment, the spring main body 12a, the reel gear locking protrusion 12b, and the reel gear cap locking protrusion 12c are formed by bending a linear member of a material to be a spring having the above-mentioned spring constant. , Are integrally molded.

  The reel gear locking projection 12 b is locked in the first spring locking hole 11 e of the reel gear 11. The reel gear cap locking projection 12 c is locked in the second spring locking hole 13 e of the reel gear cap 13.

  The torsion coil spring 12 is assembled to the reel gear 11 and the reel gear cap 13 in a state where it is compressed in the direction in which the diameter is reduced, so that the torsion coil spring 12 tries to restore the diameter at no load by the restoring force. Have a biasing force. In the present embodiment, the biasing force of the torsion coil spring 12 moves the reel gear 11 and the reel gear cap 13 in the direction in which the claw portion 13 d of the reel gear cap 13 is pressed against the first abutment portion 11 g of the hole 11 c of the reel gear 11. And is a force that tries to rotate relative to each other.

The reel gear cap 13 is a member connected to the reel gear 11 via the torsion coil spring 12 so as to be relatively rotatable with respect to the reel gear 11 within a predetermined range around the rotation center of the reel gear 11. The reel gear cap 13 is fixed to the center portion 22 of the reel 21.
The reel gear cap 13 has a disk portion 13a, a round hole portion 13b, a peripheral plate 13c, a claw portion 13d, and a second spring locking hole 13e, and has a U-shaped in a radial cross section. It is a member.

  The disk portion 13a is a disk-shaped member that can rotate around the axis center of the pivot shaft 18 as a rotation center. The round hole portion 13b is formed at the center of the disc portion 13a. The peripheral plate 13c is formed on the outer peripheral portion of the disk portion 13a.

  The claws 13 d are provided at two places spaced by 180 degrees in the circumferential direction of the disc portion 13 a. The claw portion 13d is inserted into the hole 11c of the reel gear 11, and is formed in a hook shape that is caught in the hole 11c and prevented from coming off. In the state where the claws 13d are inserted into the holes 11c, the reel gear cap 13 can not be separated from the reel gear 11 by the action of the claws 13d. The length dimension of the claw portion 13 d in the circumferential direction of the disk portion 13 a is smaller than the length dimension of the hole portion 11 c of the reel gear 11 in the circumferential direction.

  The second spring locking hole 13e is a hole formed in a part of the disc portion 13a. The reel gear cap locking projection 12 c of the torsion coil spring 12 is inserted into the second spring locking hole 13 e.

FIG. 6 is a side view of the reel rotation mechanism 100. As shown in FIG. FIG. 7 is a cross-sectional view taken along line AA of FIG.
As shown in FIGS. 6 and 7, the reel gear 11 and the reel gear cap 13 are connected to each other in a state where the claw portion 13d of the reel gear cap 13 is inserted into the hole 11c of the reel gear 11. The hole 11c of the reel gear 11 and the claws 13d of the reel gear cap 13 form a connecting mechanism for connecting the reel gear 11 and the reel gear cap 13 to each other in the present embodiment.

  The hole 11 c of the reel gear 11 and the claw 13 d of the reel gear cap 13 can be moved relative to each other by one step of the motor 14.

  Next, the operation of the reel rotation mechanism 100 will be described. FIG. 8 is a schematic view at the time of stop for explaining the operation of the reel rotation mechanism 100.

FIG. 10 is a schematic view at a constant speed for explaining the operation of the reel rotation mechanism 100.

It is an enlarged view which shows a relation. 11 (a) is a schematic front view of the reel rotating mechanism 100, and FIG. 11 (b) is a positional relationship between the hole 11c and the claw 13d. FIG. 12 (a) is a schematic front view of the reel rotation mechanism 100, and FIG. 12 (b) shows the hole 11c and the claw 13d. It is an enlarged view which shows the positional relationship of.

  In the following description, the left reel unit 64 of the three reel units 64, 65, 66 will be described as an example. As for the middle reel unit 65 and the right reel unit 66, since the reel rotation mechanism 100 operates similarly to the left reel unit 64, the overlapping description will be omitted.

  As shown in FIG. 9, with the drive of the motor 14, the reel gear 11 starts to rotate, and the reel 21 rotates via the reel gear cap 13. The reel gear 11 accelerates at the beginning of rotation and gradually increases the number of rotations until constant speed rotation. At the time of acceleration, the torsion coil spring 12 is elastically deformed by the force of the torque of the motor 14 and the inertia of the reel 21. As the reel gear 11 accelerates and rotates, the claw portion 13 d of the reel gear cap 13 abuts on the second abutment portion 11 h.

  In the reel rotation mechanism 100 of the present embodiment, when the acceleration at the start of rotation sharply rises, a part of the rotational torque transmitted from the motor 14 to the reel gear cap 13 is absorbed as elastic deformation of the torsion coil spring 12. For this reason, a large load that causes the motor 14 to be out of step is not easily applied to the motor 14. Further, after the claws 13d of the reel gear cap 13 abut on the second abutment portion 11h, the reel gear cap 13 and the reel 21 according to the reduction ratio determined by the number of teeth of the pinion 16 and the number of teeth of the reel gear 11. Rotates at a stable acceleration.

  The acceleration control by the motor 14 ends when the reel 21 reaches a predetermined rotational speed, and then the motor 14 rotates the pinion 16 at a constant speed. During this constant speed rotation, the force absorbed by the torsion coil spring 12 as elastic deformation of the torsion coil spring 12 at the time of acceleration is transmitted to the reel gear cap 13 by the restoring force of the torsion coil spring 12. Thus, when the motor 14 is controlled to rotate at a constant speed, the claw portion 13 d is in contact with the first abutment portion 11 g.

  As described above, in the present embodiment, during acceleration, the claw portion 13d of the reel gear cap 13 moves until it abuts on the second abutment portion 11h, thereby absorbing a rapid acceleration component while the torsion coil spring 12 absorbs the reel gear 11 and the reel gear cap 13 rotate, so that the motor 14 can be prevented from being out of step.

  While the reel gear 11 performs acceleration operation, constant speed operation, deceleration operation, and stop operation in the reel rotation mechanism 100, the compression coil spring 19 always applies a load in the thrust direction to the center portion 22 of the reel 21. I have a weak brake. For this reason, in the present embodiment, the bouncing stop phenomenon hardly occurs due to the backlash between the pinion 16 and the flat teeth 11 a when the reel 21 is stopped.

  As described above, in the reel rotation mechanism 100 of the present embodiment, the reel gear 11 and the reel gear cap 13 are connected by the torsion coil spring 12 and the left reel unit 64 starts to rotate and the left reel unit 64 accelerates. Since the rotational force is transmitted from the reel gear 11 to the reel gear cap 13 via the torsion coil spring 12, the motor 14 is unlikely to be out of step.

  The force transmitted to the torsion coil spring 12 is accumulated in the torsion coil spring 12 during acceleration of the reel gear 11, but is canceled after the reel gear 11 shifts to constant speed rotation. For this reason, even when the rotation and stop of the reel gear 11 are repeated frequently, it is difficult to be in a high load state leading to the step out of the motor 14.

  The claws 13 d formed on the reel gear cap 13 of the reel rotation mechanism 100 according to the present embodiment have holes so that the claws 13 d can be moved within a predetermined range with respect to the holes 11 c of the reel gear 11. It is attached to the part 11c. Therefore, the hole portion 11c and the claw portion 13d form a connecting mechanism that regulates the relative rotation of the reel gear cap 13 with respect to the reel gear 11 with the rotation center of the reel gear 11 as the rotation center. As a result, it is possible to reduce the bound stop phenomenon when the left reel unit 64 is stopped while buffering a large inertial force that leads to the step out of the motor 14 to the torsion coil spring 12 serving as an absorber.

  Further, in the reel rotation mechanism 100, since the absorber connecting the reel gear 11 and the reel gear cap 13 is the torsion coil spring 12, the material can be easily obtained, can be manufactured at low cost, and has less distortion.

  Further, in the reel rotation mechanism 100, since the claw portion 13d is hooked and connected to the hole portion 11c, the assembly is easy and difficult to remove.

  Further, in the reel rotation mechanism 100, when the claw portion 13d of the reel gear cap 13 abuts on the first abutment portion 11g of the hole portion 11c at no load, the reel gear 11 and the reel gear cap 13 do not load. It is possible to prevent rash. That is, in the present embodiment, since the torsion coil spring 12 has a biasing force such that the claw portion 13d is in contact with the hole portion 11c when the left reel unit 64 is at rest, When the reel unit 64 is at rest, the left reel unit 64 does not easily shake.

(Modification 1)
A modification of the above embodiment will be described.
FIG. 13 is a longitudinal sectional view of a modification of the reel rotation mechanism.
As shown in FIG. 13, in one modification of the reel rotation mechanism 100, in addition to the brake by the compression coil spring 19 and the center cap 20 shown in FIG. 4, the torsion coil spring 12 is in the thrust direction the reel gear 11 and the reel gear cap. By generating an urging force so as to push and unfold 13, the relative rotation of the reel gear cap 13 with respect to the reel gear 11 can be braked. In this modification, the torsion coil spring 12 applies a weak brake to the movement of the claw portion 13d in the hole portion 11c, so that the swing of the reel 21 when the motor 14 is stopped from the deceleration state, The play of the reel 21 can be reduced.

(Modification 2)
Another modification of the above embodiment will be described.
FIG. 14 is a schematic view of the reel rotation mechanism 100 according to a modification of the modification, in which (a) is a schematic front view of the reel rotation mechanism 100, and (b) shows the positional relationship between the hole 11c and the claw 13d. It is an enlarged view which shows. FIG. 15 is a schematic view during acceleration of a modification of the reel rotation mechanism 100, where (a) is a schematic front view of the reel rotation mechanism 100, and (b) shows the positional relationship between the hole 11c and the claw 13d. It is an enlarged view which shows. FIG. 16 is a schematic view during deceleration of a modification of the reel rotation mechanism 100, where (a) is a schematic front view of the reel rotation mechanism 100, and (b) shows the positional relationship between the hole 11c and the claw 13d. It is an enlarged view which shows.

  As shown in FIG. 14, another modification of the reel rotation mechanism 100 is in a no-load state with respect to the torsion coil spring 12 in the hole portion 11 c of the reel gear 11 into which the claw portion 13 d of the reel gear cap 13 is inserted. Attachment of the torsion coil spring 12 to the reel gear 11 and the reel gear cap 13 so that the claw portion 13d is positioned at the central holding portion 11i which is a substantially central portion between the first abutment portion 11g and the second abutment portion 11h. The state has been decided.

  As shown in FIG. 15, when the reel gear 11 accelerates as the motor 14 accelerates, the torsion coil spring 12 receives a force elastically deformed from the reel gear 11 in the arrow direction F2, which is the contraction direction, for example. As the reel gear 11 accelerates and rotates, the claw portion 13d of the reel gear cap 13 approaches the second abutment portion 11h, and the claw portion 13d abuts on the second abutment portion 11h.

  Thereafter, in the reel gear 11, as the motor 14 shifts to constant speed rotation control, the rotational inertia force decreases. For this reason, after the motor 14 shifts to constant speed rotation control, the torsion coil spring 12 is deformed by the restoring force of the torsion coil spring 12 so that the claw portion 13d of the reel gear cap 13 is held by the central holding portion 11i. Do.

  As shown in FIG. 16, at the time of deceleration of the reel gear 11 accompanying the deceleration of the motor 14, the torsion coil spring 12 is in the reverse direction (for example, arrow direction F1 which is a spreading direction) to the deformation of the torsion coil spring 12 at the above acceleration. The elastically deformed force is received from the rotating reel 21. As the reel gear 11 decelerates and rotates, the claw portion 13d of the reel gear cap 13 approaches the first abutment portion 11g and abuts on the first abutment portion 11g.

  Thereafter, after the motor 14 shifts from deceleration to stop, the claw portion 13d that contacts the first abutment portion 11g during deceleration is moved to the central holding portion 11i by the restoring force of the torsion coil spring 12 and held. Be done.

  In the reel rotation mechanism 100 according to the present modification, the claw portion 13 d of the reel gear cap 13 is held by the central holding portion 11 i of the hole portion 11 c when no load is applied. At this time, the reel gear 11 and the reel gear cap 13 can be prevented from coming into contact with each other.

  In this modification, in addition to the reduction in the step-out of the motor 14 during acceleration in the first embodiment, the step-out of the motor 14 is also performed by the action of the torsion coil spring 12 during deceleration control of the motor 14 for stopping the reel 21. It has been reduced.

Further, in the technology related to the present embodiment, when the reel unit is stopped, it is referred to as a bound stop phenomenon when the reel unit is stopped due to the backlash due to the teeth of each gear between the motor and the reel unit. Shaking may occur. As a measure for reducing the bound stop phenomenon, in the technology related to the present embodiment, the friction resistance to the rotation of the reel is constantly applied to the reel to make a brake, and the amount of movement of the reel due to the bound stop phenomenon occurring when the reel stops. It has been done to reduce the However, in the configuration in which the brake is always applied to the reel, since it is necessary to compensate for the loss due to the brake, it becomes necessary to adopt a motor with a large torque.
On the other hand, in the present embodiment, since the force that causes the bound stop phenomenon is absorbed by the torsion coil spring 12 in the reel deceleration process, the bound stop phenomenon is less noticeable.

  As mentioned above, although the embodiment of the present invention and its modification were explained in full detail with reference to drawings, the concrete composition is not restricted to this embodiment, Design change of the range which does not deviate from the gist of the present invention, etc. included.

  For example, instead of the torsion coil spring 12 described in the above embodiment, a biasing member of another material or shape such as a polymer member made of rubber or the like, a tension coil spring, or the like may use the reel gear 11 and the reel gear cap 13. Even when connected, it functions as an absorber similar to the torsion coil spring 12 of the first embodiment.

In addition, contrary to the configuration described in the first embodiment, the torsion coil spring 12 has an urging force that causes the claw portion 13d to abut on the second abutment portion 11h in a non-loaded state. In contrast to the first embodiment, out of step of the motor 14 is reduced by the action of the torsion coil spring 12 at the time of deceleration control of the motor 14 for stopping the reel 21.
In this case, if the hole 11c of the reel gear 11 and the claws 13d of the reel gear cap 13 are relatively movable by one step of the motor 14, the torsion coil spring 12 stops the left reel unit 64 when stopping. The reel 21 reverses by one step. This return operation can be used as a reel action effect.
