Description

Prize acquisition game machine

The present invention relates to a prize acquisition game device such as a crane game.

では In amusement facilities and the like, a prize acquisition game device that operates a prize gripper to convey a stuffed animal such as a stuffed animal to a prize payout exit is widespread. When the gripping force of the prize gripping portion is increased, the number of prizes to be paid out increases, and when the gripping force of the prize gripping portion is weakened, the number of prizes to be paid out tends to decrease. Therefore, a prize acquisition game device that can adjust the gripping force of the prize gripping portion has been proposed (for example, see Patent Documents 1 and 2).

The crane game machine described in Patent Literature 1 changes the gripping force of the arm so that the actual prize acquisition rate counted by the control unit approaches a preset prize acquisition rate. More specifically, the driving time of the motor that opens and closes the arm is extended if the prize acquisition rate is lower than the target, and the driving time of the motor is reduced if the prize acquisition rate is higher than the target. When the driving time of the motor is extended, the coil spring of the arm is extended correspondingly, and the gripping force is increased.

The game device described in Patent Literature 2 includes a pair of upper pressing members and a lower pressing member sandwiching base ends of a plurality of arms, a coil spring for urging the lower pressing members toward the upper pressing members, A peripheral wall plate that restricts movement of the pressing member. The upper pressing member and the coil spring move up and down by a ball screw. The gripping force of the arm is determined by the urging force of a coil spring that causes the arm to follow the upper pressing member. When the movement of the upper pressing member is restricted and the coil spring approaches the upper pressing member, the coil spring is compressed and the gripping force of the arm increases.

The crane game machine described in Patent Document 1 monitors the prize acquisition rate and adjusts the drive time of the motor, and does not refer to the opening / closing angle of each arm at all. Similarly, the game device described in Patent Document 2 adjusts the biasing force of the coil spring by detecting the positional relationship between the single upper pressing member and the coil spring, and does not refer to the opening / closing angle of each arm. Not. That is, in the prize acquisition game devices described in

Patent Documents

1 and 2, the gripping force of the prize gripper cannot be adjusted based on the opening / closing angle of each arm.

JP 2012-29825 A JP 2016-1430372 A

However, not all arms touch the prize at the same time. The energy storage of the urging members such as the coil springs for determining the gripping force of the arm starts in order from the arm stopped in contact with the prize. The opening / closing angle of the arm varies according to the time difference, and the magnitude of the gripping force of the arm also varies according to the opening / closing angle. Unless the driving time of the driving source is adjusted based on the opening / closing angles of the respective arms, the gripping force of the arms cannot be adjusted appropriately.
Therefore, an object of the present invention is to provide a prize acquisition game device that can adjust the gripping force of the prize gripping part based on the opening / closing angle of each arm.

One embodiment of the present invention is a prize acquisition game device provided with at least one prize gripper for gripping a prize. The holding force of each premium holding unit is adjusted by the control unit. Each premium holding unit includes a single drive source, a plurality of arms, and a plurality of sensors. The driving force supplied from a single driving source is distributed to a plurality of arms. When the driving force is distributed, each arm opens and closes. Sensors are provided for all arms, respectively. Each sensor detects the opening / closing angle of the corresponding arm. The control unit controls driving of a single driving source based on the plurality of opening / closing angles detected by the sensor.

According to this aspect, even if the opening / closing angles of the arms vary, they can be individually detected. In a configuration in which a single drive source is driven to open and close a plurality of arms, instead of detecting the opening and closing angles of the plurality of arms in a tight manner, the opening and closing angles of each arm are individually detected. The gripping force can be adjusted appropriately.

In the above aspect, each premium holding portion is connected to each arm, and a spring seat member for rotating the arm in the closing direction, and is attached to each arm and stored when the spring seat member moves in the arm closing direction. And a biasing coil spring.

According to this aspect, a coil spring can be used as the biasing member interposed between the arm and the drive source. With a coil spring, it is easy to grasp the biasing force accumulated as a delay of the opening and closing angle of the arm with respect to the movement of the spring seat member. The coil spring may be a torsion coil spring that receives a torsional moment about the central axis from the rotating spring seat member, or a tension coil spring that receives a tensile stress in the expansion and contraction direction from the swinging spring seat member. You may.

In the above aspect, each prize gripper may further include a feed screw for converting a rotational movement of the screw shaft into a linear movement of the nut, and a link mechanism for connecting each arm to the nut. A single drive source may rotate the screw shaft, and each arm may rotate in the opening or closing direction in conjunction with the linear movement of the nut.

According to this aspect, the driving force of a single driving source can be distributed to a plurality of arms by a simple configuration combining a feed screw and a link mechanism. Since the prize gripper can be configured compactly and at low cost, it is particularly suitable for a prize acquisition game device having a small housing.

In the above aspect, the control unit may control the driving of the single drive source based on the opening and closing angle of the arm having the largest opening and closing angle in the closing direction.

アーム The arm with the largest opening / closing angle in the closing direction has a lower gripping force than the other arms. When a prize is gripped by a plurality of arms, the prize escapes and cannot be gripped strongly if the gripping force of the arm supported from the opposite direction is weak, even if any one of the arms has a strong gripping force. That is, the arm having a weak gripping force greatly affects the gripping force of the prize gripping portion as a whole. According to this aspect, it is possible to control the driving of the single drive source based on the opening and closing angle of the arm having the weakest gripping force, and to suitably adjust the gripping force of the premium holding portion.

In the above aspect, when the number of arms is 2n + 1, the control unit controls the driving of the single drive source based on the opening / closing angle of the arm having the (n + 1) th largest opening / closing angle in the closing direction. When the number of arms is 2n, the control unit determines whether the opening / closing angle in the closing direction is the n-th largest arm opening / closing angle, the (n + 1) th largest arm opening / closing angle, or the n-th largest arm opening / closing angle and the (n + 1) th arm. The single drive source is driven based on one of the average values of the opening angle and the opening angle of the arm.

によって Depending on the shape of the prize and the number of arms, it may be preferable to use the arm other than the arm having the weakest gripping force as a reference. According to this aspect, when the number of arms is, for example, three, the gripping force of the entire prize gripper can be suitably adjusted based on the opening and closing angle of the arm having the second gripping force. When the number of arms is, for example, four, the opening and closing angle of the arm with the third gripping force may be used as a reference, or the opening and closing angle of the arm with the second gripping force may be used as a reference. May be used as a reference. The holding force of the prize holding portion can be suitably adjusted according to the shape of the prize and the number of arms.

In the above aspect, the control unit calculates a weighted average value in which the arm with the largest opening / closing angle in the closing direction has a larger weight than the other arms, and based on the weighted average value, calculates the single drive source. The driving may be controlled.

According to this aspect, the weight of each open / close angle is finely set in accordance with the shape of the prize or the number of arms by appropriately considering the opening / closing angles of the plurality of arms, that is, the gripping force, according to the opening / closing state. The gripping force of the gripper can be suitably adjusted.

In the above aspect, a prize payout sensor for detecting the number of paid out prizes may be further provided. The control unit may acquire a payout index based on the number of paid-out prizes, and control driving of a single drive source based on the payout index.

の一 An example of the payout index is a payout rate obtained by dividing the purchase amount of the paid out prize by the amount of input. For example, if a premium purchased at 500 yen is acquired at 1000 yen, the payout rate will be 50%. According to this aspect, in the control based on the detection results of the plurality of sensors described above, adjustment based on the payout rate can be further added. In an amusement facility, there is no need for the operator to frequently monitor the payout rate or manually adjust the holding force of the prize holding unit. The burden on the operator can be reduced. The payout index is not limited to the payout rate, and may be the number of premiums paid out per unit time. The payout index may be calculated by the control unit and acquired by itself, or may be acquired from outside via a network or the like.

According to the present invention, it is possible to provide a prize acquisition game device that can adjust the gripping force of the prize gripping part based on the opening / closing angle of each arm.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In each of the drawings, components denoted by the same reference numerals have the same or similar configurations. The prize acquisition game device 1 according to one embodiment of the present invention individually detects the opening / closing angles α, β, γ of all the

arms

43A, 43B, 43C, and based on the plurality of opening / closing angles α, β, γ. One of the features is to control the driving of one motor 42 (see FIG. 5).

When α> β> γ, for example, the drive of the motor 42 may be controlled based on the largest opening angle α among the opening angles α, β, and γ. For example, the drive of the motor 42 may be controlled based on the second largest opening / closing angle β. For example, the drive of the motor 42 may be controlled based on a weighted average value (w1 × α + w2 × β + w3 × γ) / (w1 + w2 + w3) having a weight of w1> w2> w3.

Since the gripping force of the arms 43A, 42B, and 42C varies depending on the opening / closing angles α, β, and γ, the gripping force of the

arms

43A and 43B supported from the opposite direction even if the gripping force of any one arm 43C is strong. If it is weak, the prize escapes and cannot be gripped strongly. According to the present embodiment, since the drive of the motor 42 is controlled based on the opening / closing angles α, β, γ of the

arms

43A, 43B, 43C, it is possible to suitably adjust the gripping force of the entire premium holding portion 40. Hereinafter, each configuration will be described in detail with reference to FIGS. 1 to 16.

FIG. 2 is a front view showing an example of the premium holding portion 40 according to the present invention. As shown in FIG. 2, the premium holding portion 40 includes a plurality of arms 43. In the example shown in FIG. 2, the premium holding portion 40 includes three

arms

43A, 43B, and 43C. The number of the arms 43 may be two or four or more. The premium holding portion 40 further includes a bracket 41 and a control board 60 fixed to the bracket 41.

FIG. 3 is a sectional view taken along the line III-III shown in FIG. As shown in FIG. 3, the premium holding portion 40 further includes a single motor 42 attached to the bracket 41, a feed screw (the screw shaft 53 and the nut 54), and an angle sensor 44. The motor 42 is, for example, a DC brush motor with a gear head, and is an example of a drive source. Note that the premium holding portion 40 may be configured by a pneumatic or hydraulic drive source instead of the motor 42. A motor shaft gear 51 is mounted on the output shaft of the motor 42 via a gear head.

The feed screw is a slide screw, a ball screw, or the like, and converts the rotational movement of the screw shaft 53 into a linear movement of the nut 54. A screw shaft gear 52 is mounted on the screw shaft 53. The screw shaft gear 52 meshes with the motor shaft gear 51. The nut 54 and the arm 43 are connected by a link mechanism including the first and

second parts

55 and 56. The first component 55 is fixed to the nut 54. The rotation center of the second component 56 is rotatably supported by the base end 58 of the arm 43. One end of the second component 56 is connected to a slot formed in the first component 55.

In the example shown in FIG. 3, the link mechanism is a swinging slider crank, and when the first component 55 moves up and down, one end of the second component 56 slides in a slot formed in the first component 55 to move the second component 56 into the second component. The part 56 swings. More specifically, when the first component 55 moves upward, the second component 56 rotates the arm 43 in the closing direction D1. When the first component 55 moves downward, the second component 56 rotates the arm 43 in the opening direction D2.

FIG. 4 is an exploded perspective view showing a base end portion 58 of the arm 43. As shown in FIG. 4, the arm 43 is provided with an urging member. The urging force of the urging member determines the gripping force with which the arm 43 presses the premium. In the example shown in FIG. 4,

coil springs

57L and 57R are provided as urging members at a base end portion 58 of the arm 43.

The coil springs 57L and 57R are torsion coil springs, and are attached to the arm 43 such that the center axis of the coil coincides with the rotation axis 581 of the base 58. The biasing member of the arm 43 is not limited to a torsion coil spring, and may be a spring such as a tension coil spring or another elastic member. The arm at one end of the coil springs 57L, 57R is bent and fixed to the base end 58.

The coil spring (closing direction spring) 57L urges the arm 43 toward the prize to give a gripping force for the arm 43 to press the prize. In a combination of the large arm 43 and the small prize, the weight of the arm 43 sometimes acts as a gripping force for pressing the prize. The coil spring (opening direction spring) 57R urges the arm 43 in the opening direction D2 to balance the weight of the arm 43.

The second component 56 of the link mechanism is constituted by a pair of

spring seat members

56L, 56R that sandwich the base end 58. The rotation centers of the

spring seat members

56L and 56R coincide with the rotation shaft 581 of the base end portion 58. Spring seats that support the other ends of the

coil springs

57L and 57R are formed at the rotation centers of the

spring seat members

56L and 56R, respectively.

When the spring seat member 56L is rotated in the closing direction D1 via the coil spring 57L in a state where the arm 43 comes into contact with the prize and hardly moves, the arm on the other end side of the coil spring 57L becomes a spring seat. And the urging force of the coil spring 57L increases. When the spring seat member 56L reversely rotates in the direction D2 for opening the arm 43, the urging force of the coil spring 57L decreases.

FIG. 5 is a cross-sectional view taken along the line VV shown in FIG. As shown in FIG. 5, one of the features of the premium holding portion 40 according to the present invention is that all the arms 43 (43A, 43B, 43C) are provided with angle sensors 44 (44A, 44B, 44C). It is. In the example shown in FIG. 5, the angle sensor 44 is a volume that outputs a voltage according to the rotation angle. Note that the angle sensor 44 may be a photo interrupter or the like. The angle sensor 44 meshes with a gear 582 formed around a rotation axis 581 of the base end 58 of the arm 43. The control unit 61, which will be described later, controls the driving of the single motor 42 based on the opening / closing angles α, β, γ of the angle sensors 44.

FIG. 6 is a right side view showing the premium holding portion 40. As shown in FIG. 6, the premium holding portion 40 further includes an up / down sensor 45 that detects the up / down position of the nut 54. A vertical sensor gear 59 is mounted on a rotation shaft 581 of the base end portion 58. The up / down sensor 45 has the same volume as the angle sensor 44 and is engaged with the up / down sensor gear 59. Further, the premium holding unit 40 further includes a lower limit sensor 46 (shown in FIG. 7) for detecting a lower limit position and an upper limit sensor 47 (shown in FIG. 7) for detecting an upper limit position. The lower limit sensor 46 and the upper limit sensor 47 use, for example, a photo interrupter, and extend to an end of a range in which the nut 54 can move by a sensor dog (not shown) attached to a nut 54 (shown in FIG. 3) of the feed screw blocking light. Detect that it has moved. Note that the contact of the sensor dog with the pressure-sensitive sensor may be detected.

FIG. 7 is a block diagram showing an example of the internal configuration of the premium holding portion 40. As shown in FIG. As shown in FIG. 7, the control board 60 includes a control unit 61 and a storage unit 62. The control section 61 and the storage section 62 are not limited to the control board 60 mounted on the premium holding section 40, and may include a board mounted on the lower field structure 5 or the middle field structure 6.

The storage unit 62 has a function of storing various programs and an operating system. The storage unit 62 also has a function as a work area in which the control unit 61 temporarily stores various data during processing. The storage unit 62 is realized by, for example, a ROM. Note that a RAM or the like may be used. The ROM stores various programs and data necessary for controlling the driving of the motor 42. The ROM is, for example, one of a volatile memory represented by a DRAM, a non-rewritable nonvolatile memory represented by a mask ROM, and a rewritable nonvolatile memory represented by a flash memory, or an appropriate combination of these. Be composed.

The control unit 61 can be realized by, for example, a function of a CPU mounted on the control board 60. The CPU expands the program stored in the ROM on the memory of the storage unit 62, executes the program, and realizes various functions in a device included in the premium holding unit 40, thereby cooperating with other hardware units and components. It has a gripping force control unit 611 that operates to adjust the gripping force of the premium holding unit 40, and an adjustment index determining unit 612 that determines an adjustment index to be referred to when the gripping force control unit 611 is executed. . The control unit 61 may further include a payout index calculating unit 613 that calculates a payout index based on the number of paid out prizes.

FIG. 8 is a flowchart showing an example of a procedure for controlling the driving of a single motor 42 based on a plurality of opening / closing angles α, β, γ. When a player's operation is input to the first operation unit 31, the premium holding unit 40 moves in accordance with the operation of the player (step S1). When all the player's operations are completed, the prize gripper 40 descends and starts the operation of closing the plurality of arms 43 (step S2). The arm 43 stops when it comes into contact with the premium or closes to the limit angle. If the arm 43 has not stopped, the control section 61 returns to step S2 and repeats the closing operation of the arm 43 (step S3).

On the other hand, if the arms 43 are stopped, the opening / closing angle of each arm 43 is detected (step S3). The control unit 61 (adjustment index determination means 612) determines an adjustment index of the gripping force by applying the detected opening / closing angle to a condition set by the operator (for example, the maximum opening / closing angle) (step S5). Note that the adjustment index of the gripping force is not limited to the opening / closing angle α of the arm 43A having the largest opening / closing angle in the closing direction D1, and conditions can be appropriately selected according to the shape of the prize and the number of the arms 43.

For example, when the number of the arms 43 is 2n + 1, the opening and closing angle in the closing direction D1 may be the n + 1-th largest opening and closing angle of the arm 43. For example, when the number of the arms 43 is 2n, the opening / closing angle of the (n + 1) th largest arm 43 or the opening / closing angle of the nth largest arm 43 may be used. The opening and closing angle of the arm 43 may be the (n + 1) th largest arm. The average value thereof may be used.

For example, a weighted average value (w1 × α + w2 × β + w3 × γ) / (w1 + w2 + w3) in which the arm 43A having the largest opening / closing angle in the closing direction D1 has a larger weight than the

other arms

43B and 43C is calculated. The average value may be added. The control unit 61 (gripping force control means 611) controls the driving of the single motor 42 based on the gripping force adjustment index determined in step S5 (step S6).

(4) The control unit 61 can also add a correction value such as a payout index to the main adjustment index. The control unit 61 (payout index calculating means) acquires a payout index based on the number of prizes paid out. An example of the payout index is a payout rate obtained by dividing the number of paid out prizes by the amount of money input. The payout index is not limited to the payout rate, and may be the number of premiums paid out per unit time. The payout index may be calculated by the control unit and acquired by itself, or may be acquired from outside via a network or the like.

When adjusting the holding force of the prize holding unit 40 based on the payout index, the

fields

18 and 19 are divided into a plurality of parts, the payout rate is counted for each field, and the holding force of the prize holding unit 40 is adjusted. May be. FIG. 9 is an example in which the field 18 is divided into a plurality of areas. As shown in FIG. 9, the field 18 may be divided into areas 181 to 182 and areas 183 to 184.

フィールド Although not shown, the field 18 may be divided into areas 181 to 183 and an area 184. The field 18 may be divided into an area 181 and areas 182 to 184. The field 18 may be divided into an area 181, an area 182 to 183, and an area 184. It may be further divided finely. For example, if the area where the prize is arranged is reduced according to the stock number of the prize and another prize is added to the empty space, the reduced prize can be arranged with good appearance.

In the example shown in FIG. 9, a physical partition may be further provided at the boundary of the field 18. Installing a physical partition makes it easier to understand visually. Further, it is possible to prevent the prizes of the adjacent areas from being mixed, so that the types of the prizes are clearly divided. Furthermore, if the adjustment of the gripping force described above with reference to FIGS. 1 to 8 is performed for each area, it is possible to appropriately handle the payout rate of a prize having a different unit price for each divided field. Becomes possible. The position of the prize gripper 40 in the area partitioned by the partition can be grasped from a sensor provided in a horizontal moving mechanism of the prize gripper 40 (not shown) or the number of steps of a stepping motor that performs horizontal movement.

In the prize obtaining game apparatus 1 according to the present embodiment configured as described above, the driving force of the single motor 42 is distributed to the plurality of arms 43. Since the prize holding section 40 can be configured compactly and inexpensively, it is suitable for the prize obtaining game apparatus 1 which is divided into upper and lower tiers and the

prize accommodation sections

16 and 17 are small. As shown in FIG. 5, since the angle sensors 44 are provided on all the arms 43, even if the opening and closing angles of the

arms

43A, 43B and 43C vary, the opening and closing angles α, β and γ are individually determined. Therefore, the holding force of the prize holding unit 40 can be adjusted appropriately.

When α> β> γ, for example, the drive of the motor 42 is controlled based on the largest opening angle α among the opening angles α, β, and γ. When the prize is gripped by the plurality of

arms

43A, 43B, 43C, the prize escapes and is strongly gripped if the gripping force of the

arms

43A, 43B supported from the opposite direction is weak, even if any one of the arms 43C has a strong gripping force. Can not do it. Therefore, based on the opening / closing angle of the arm 43A having the weakest gripping force, the driving of the single motor 42 can be controlled, and the gripping force of the premium holding portion 40 can be adjusted appropriately.

Depending on the shape of the prize and the number of the arms 43, it may be preferable to use the

other arms

43B and 43C as a reference instead of the arm 43A having the weakest gripping force. For example, the drive of the motor 42 is controlled based on a weighted average value (w1 × α + w2 × β + w3 × γ) / (w1 + w2 + w3) having a weight of w1> w2> w3, and is adjusted according to the shape of the prize and the number of the arms 43. If the weight of each opening / closing angle is set finely, the gripping force of the premium holding portion 40 can be adjusted appropriately. For example, the drive of the motor 42 may be controlled based on the arm 43 having a moderate gripping force. The condition for determining the adjustment index is not particularly limited, and can be appropriately selected according to the shape of the prize and the number of the arms 43.

Next, with reference to FIGS. 10 to 16, features of the casing 2 of the premium obtaining game apparatus 1 of the present embodiment will be described. First, the coin shoot 25 will be described with reference to FIGS. As described above, the housing 2 has the first and second
