DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing device for dispensing a three-dimensional material to be dispensed, such as an eraser, and more particularly to a reliable dispensing device and a compact device.

[0002]

2. Description of the Related Art In general, a device for dispensing a three-dimensional material to be dispensed is configured such that a large number of materials to be dispensed are accommodated in a material-accommodating chamber and are dispensed one by one. For example, a conventional eraser dispensing device is configured such that rod-shaped erasers are stacked one by one in an eraser storage chamber extending in a vertical direction in a horizontal posture, and the bottom eraser is pushed out of the eraser storage chamber by a slider. Was. The eraser storage chamber is formed with a payout port from which the bottom eraser is paid out and an opening that allows the slider to enter. The slider is linearly moved by the slider driving device between an eraser pushing position where the slider enters the eraser storage chamber and pushes out the eraser, and a retracted position where the slider is retracted outside the eraser storage chamber. At the time of dispensing, the slider is moved from the retracted position to the eraser pushing position, and dispenses the bottom eraser from the dispensing port. After dispensing, the slider is located at the bottom of the eraser storage chamber instead of the bottom eraser, is stacked in the eraser storage chamber, and is in a state of supporting the eraser to be dispensed later from below. Therefore, when the slider is retracted from the eraser storage chamber, the eraser on the slider falls to the lowermost portion of the eraser storage chamber and is ready for the next payout. The eraser dispensing device can be used for dispensing other three-dimensional materials to be dispensed.

[0003]

However, the above-described conventional dispensing apparatus has a problem of lack of flexibility. For example, when the material to be paid out has a longitudinal shape whose length is longer than the thickness, the material to be paid out should be stored in the material to be paid out storage chamber in a posture in which the longitudinal direction is horizontal, For some reason, the material to be paid may be stored in the material-receiving room in a posture in which the longitudinal direction is vertical. On the other hand, the vertical dimension of the payout outlet is the thickness of the material to be paid out, for example, the thickness of the eraser in a device for discharging a rectangular parallelepiped eraser to allow the passage of only one material to be paid out. That is, it is only slightly larger than the dimension in the direction perpendicular to the longitudinal direction and the width direction. Therefore, when the material to be paid having a longitudinal shape is accommodated in the material to be paid accommodation chamber in a vertical posture, the material to be paid cannot pass through the payout port and is not paid out. Also, when the material to be paid out includes a material having an unscheduled thickness, the payout becomes impossible. If the thickness of the material to be paid is larger than the inner diameter of the payout port, the material to be paid is
Even if the material is stored in the material-receiving chamber in a posture in which the longitudinal direction is horizontal, the dispensing is impossible. Furthermore, even if the material to be dispensed is a lump having the same three-dimensional dimensions as a regular hexahedron, the diagonal dimension is set to the inner dimension of the dispensing port if the posture when approaching the dispensing port is not constant. It may not be able to pass through the payout exit because it is larger, and may not be paid out smoothly.

In addition, the conventional dispensing device has a problem that it is difficult to reduce the width of the dispensing device. The material to be paid is accommodated in the material-receiving chamber in a state in which the longitudinal direction thereof coincides with the width direction of the material-receiving chamber, and the slider is parallel to the longitudinal direction of the material to be paid, that is, the material-receiving chamber. Since the slider is moved in the width direction, it is necessary to secure a space for moving the slider in addition to the installation space for the slider driving device such as the slider and the air cylinder in the width direction of the dispensing device. It is difficult. Therefore, the first to eighth inventions have been made to provide a dispensing device which is rich in flexibility and does not require the dispensing member to be moved in the width direction of the material-receiving chamber.

Forming at least a part, a frame including an inclined support surface inclined with respect to a horizontal plane in a direction orthogonal to the width direction of the material-receiving chamber, and a cross-sectional shape is circular, and at a lower end of the inclined support surface Adjacent, a dispensing rotator rotatably provided around an axis parallel to the width direction of the dispensed material accommodating chamber, and a dispensing claw protruding radially outward on an outer peripheral surface of the dispensing rotator. A dispensing member in which a dispensing claw projects from the inclined support surface toward the dispensed material accommodating chamber along with the rotation of the dispensing rotating body, and the dispensing member is disposed at a position opposite to the inclined support surface with respect to the dispensing member. A dispensing member provided on a frame;

However, if the dispensed material is pressed against the opposing surface by the dispensing member, it is separated from the dispensing member and one piece A movable wall device having a movable wall member that forms a gap allowing passage of the material to be dispensed (claim 1) .

[0006] In the dispensing device configured as described above, when the dispensing claw does not protrude from the inclined support surface toward the dispensed material accommodating chamber, the dispensed material accommodated in the dispensed material accommodating chamber is inclined. It is moved between the payout member and the movable wall member by the inclination of the support surface. At this time, the material to be paid is a movable wall
It is regulated by the regulation surface of the member, and
One piece enters between the peripheral surface and the opposite surface and the outer peripheral surface of the payout rotating body.

At this time, the dispensing claw is located between the outer peripheral surface of the dispensing rotator and the regulating surface of the movable wall member , and the first dispensed material to be dispensed first and the dispensed second. It enters between the second to-be-paid material and engages with the first to-be-paid material and rotates around the rotation axis of the payout member while pushing it. As a result, the material to be dispensed is pressed against the opposing surface of the movable wall member by the dispensing claw , the movable wall member is separated from the dispensing member, and the dispensing rotation is performed with the lower end of the opposing surface of the movable wall member.
The gap between the outer peripheral surface of the body and the body widens to form a gap that allows the passage of one material to be dispensed, and the material to be dispensed is discharged through this gap.

[0007] As described above, the material to be dispensed is the opposing surface of the movable wall member.
And the lower end of the facing surface and the outer peripheral surface of the payout rotating body.
Gap is widened and one material to be paid out is paid out
Thereby, for example, the material to be dispensed has a longitudinal shape, and the material to be dispensed should be accommodated in the material accommodating chamber in a posture in which the longitudinal direction is parallel to the width direction, but the longitudinal direction is parallel to the direction of the inclination of the inclined support surface. Even when the movable wall member is moved, the movable wall member moves to allow the material to be discharged to pass between the outer peripheral surface of the payout rotating member and the lower end of the opposing surface of the movable wall member. Is formed, and the material to be paid out is discharged. The dispensing claw is engaged with the end surface on the opposite side to the movable wall member side in the longitudinal direction of the dispensed material,
As long as the material to be dispensed can be pressed against the movable wall member, the dispensing is possible. If the length of the material to be dispensed is up to about 1.5 times the thickness, the dispensing is possible.
Further, the lower end of the outer peripheral surface of the payout rotating body and the opposing surface of the movable wall member.
Since the size of the gap formed between the part varies depending on the size of the material to be paid, a material having an unpredicted thickness is mixed into the material to be paid having a constant thickness for some reason, or Even when there is considerable variation in the thickness of the material to be paid, the material is paid out without any trouble. As described above, according to the present invention, a dispensing device with high flexibility can be obtained.

The dispensing member may be rotated about a rotation axis parallel to the width direction of the dispensed material accommodating chamber.
It does not need to be moved in the longitudinal direction like a slider. Therefore, it is easier to reduce the widthwise dimension of the dispensing device as compared to a dispensing device that performs dispensing by reciprocating movement of the slider. In addition, in a device that performs payout by a linear reciprocating motion of a slider as in the related art,
If the movable wall member is provided, the to-be-paid material accommodated in the posture in which the longitudinal direction extends vertically can be paid out. But,
In this case, it is necessary that the movable wall member can be retracted in the linear movement direction of the slider until the dispensing of the material to be paid is completed with the linear movement of the slider. growing. On the other hand, when the dispensing member is rotated, a gap is formed between the dispensing member and the movable wall member to allow passage of the dispensed material, as will be described later in detail in the description of the embodiment. If it is possible to pay out, the required movement amount of the movable wall member can be small,
The configuration of the device is easy.

It is necessary that at least the lower part of the paid-out material accommodating chamber has a width which does not allow a plurality of paid-out materials to be arranged side by side. For this reason, it is possible to use a slender shape that does not allow a plurality of materials to be paid in the width direction and the depth direction over the entire height direction, but a plurality of materials to be paid are arranged in the depth direction. With a flat shape allowing the arrangement, the number of expendable materials that can be accommodated can be increased while the expendable material accommodation chamber is made narrow. In the present invention, since the dispensing member may be rotated around the rotation axis, the dimensions of the dispensing member and its driving device in the width direction of the dispensed material accommodating chamber are linearly reciprocated by the slider. It is easy to reduce the size as compared with a conventional mechanism. Therefore,
If this feature is combined with the feature that can accommodate a large number of materials to be paid in the narrow material-to-be-paid chamber, it is possible to obtain a dispensing device that can store a large number of materials to be paid with a small width. it can. In particular, by storing a long-shaped material to be paid in a flat-shaped material-to-be-accommodated storage chamber with its longitudinal direction aligned with the width direction of the material-to-be-paid-to-be-stocked, a large number of material to be paid can be stored. In addition, the payout is performed smoothly.

[0010] Further, the upper portion of the material-receiving chamber has a shape in which a plurality of material-to-be-paid can be arranged in both the width direction and the depth direction. It is also possible to have no shape. Between the upper part and the lower part of the to-be-paid material storage chamber, there is provided a width gradually decreasing portion whose width gradually decreases downward. In this case, although the width of the dispensing device cannot be reduced, the upper portion of the dispensed material storage chamber has a three-dimensional shape, and a large number of dispensed materials can be stored. In addition, since it becomes impossible to align the direction of the paid-out material in the paid-out material accommodating room,
The direction of the material to be paid out at the payout port will not be constant, but in the payout device according to the present invention, if the shapes and relative positions of the payout member and the movable wall member are appropriately determined,
There is no problem because it is possible to pay out regardless of the direction of the paid-out material.

Further, as described in the embodiment of the present invention , the inclined support surface may form a part of the bottom surface of the material-receiving chamber, or may form the whole. In the latter case, the movable wall member is provided so as to extend in the vertical direction when not dispensed, and the inclined support surface is provided between the movable wall member and the movable wall member from the end opposite to the movable wall member in the depth direction of the material-receiving chamber. The material is always extended to a position where a gap that does not allow the material to be paid is allowed to pass.

The dispensing device according to any one of the above. The dispensing claw engages with the dispensed material on the working surface and dispenses. The working surface may be a plane extending substantially along a plane including the rotation axis of the payout rotating body, but it is desirable that the peripheral end portion intensively contact the material to be paid out in order to stabilize the payout. The optimal orientation of the working surface is determined by the relative position between the payout rotating body and the movable wall member, but it is often desirable that the working surface be slightly inclined forward with respect to the plane including the rotation axis. The curved surface whose distance from the rotation axis decreases at an accelerating rate is the second material to be paid when the payout claw enters between the material to be paid out first and the material to be paid out second. Is separated from the first material to be paid, and functions as a succeeding material to be removed surface that prevents the second material to be paid out along with the first material to be paid. In addition, when the payout claw rotates and pays out the material to be paid out, the time in contact with the material to be paid out is long, and the payout can be reliably performed.

Get in between. Then, the second eraser 56 is rotated while being pushed up by the partial cylindrical surface 68, and enters the rear side of the first eraser 56. This second eraser 56
As a result, the third eraser 56 moves toward the dispensing claw 64 and comes into contact with the curved surface 70 to be in the state shown in FIG.

In the eraser storage chamber 54, the eraser 56 is generally stored in the horizontal direction. However, the eraser 56 may be stored in a posture in which the vertical direction, that is, the longitudinal direction is oriented in the depth direction. . In this case, as shown in FIG. 10, when the dispensing member 60 is at the eraser dispensing start position, the dispensing claw 64 is engaged with the rear surface of the eraser 56,
The rotating wall member 116 is slightly rotated via the eraser 56 against the urging force of the tension coil spring 146. When the drive motor 94 is activated, the dispensing member 60 is rotated, the dispensing pawl 64 pushes the eraser 56, and the rotating wall member 116 is further rotated against the urging force of the extension coil spring 146, thereby dispensing. The gap between the pawl 64 and the rotating wall member 116 widens, and the eraser 56 is moved downward. The dispensing claw 64 rotates while rotating the eraser 56 in the direction shown by the arrow by the frictional force between the eraser 56 and the eraser 56, and the eraser 56 is in a posture in which the longitudinal direction is up and down as shown in FIG. The dispensing member 60 is temporarily stopped at a position rotated 90 degrees, and if the eraser 56 to be dispensed next has not yet sufficiently moved to the movable wall member 116 side, the vibration generated due to the impact of the stop causes Moved as far as possible.

When the dispensing member 60 is rotated again and the dispensing claw 64 exceeds the position where the dispensing claw 64 protrudes most toward the rotating wall member 116, the rotating wall member 116 is biased by the tension coil spring 146 as shown in FIG. As described above, the eraser 56 is rotated toward the original position while being sandwiched between the eraser 56 and the dispensing claw 64. During this time, the eraser 56 is gradually moved downward by the dispensing claw 64. Then, the rotating wall member 116
When the dispensing member 60 is slightly rotated after is returned to the original position, the dispensing claw 64 separates from the eraser 56,
The eraser 56 falls as shown by a two-dot chain line in FIG.
Received by shooter 220.

As described above, the eraser 56 oriented in the vertical direction is used.
Is dispensed, the eraser 56 is held between the dispensing claw 64 and the rotating wall member 116 so that the dispensing claw 64 is
To change the posture, and the rotating wall member 116
Is held between the rotating wall member 116 and the dispensing claw 64 until it returns to the original position. Rotating wall member 116 and dispensing member 60
Is closed by the eraser 56 to be dispensed, and the next eraser 56 to be dispensed is
Does not subsequently fall, whether in the horizontal or vertical direction.

The dispensing claw 64 is moved from the dispensing end position where the dispensing member 60 is rotated by 180 degrees from the eraser dispensing start position.
13 is again rotated to the eraser dispensing start position as shown by the two-dot chain line in FIG. 13, and if the second eraser 56 next to the first eraser 56 is oriented vertically, the dispensing claw 64 Penetrates below the second eraser 56, pushes it upward as shown by a two-dot chain line in FIG. 13, and comes into contact with the rear end surface of the first eraser 56.

When the eraser 56 is dispensed by the rotation of the dispensing member 60 as described above, the uneven radius roller 172 is also rotated with the rotation of the dispensing member 60. As a result, the rollers 172 having uneven radius in the eraser storage chamber 54
The eraser 56 that is in contact with the
2 and forcibly moved in the circumferential direction of the radially uneven roller 172 by frictional force, and the other eraser 56 in contact with the eraser 56 is also moved, thereby causing the bridge to move. Will be resolved. Since the eraser 56 is covered with a paper cover whose surface is coated with a resin, the coefficient of friction between the erasers 56 does not become too high at this time and the movement is not prevented. In particular, in the present embodiment, since the stepped portion 176 and the inclined surface 178 are provided, the amount of movement of the eraser 56 when the non-uniform radius roller 172 rotates is changed abruptly, and the bridge is favorably eliminated. . When the uneven radius roller 172 is rotated, the distance between the rotation axis of the uneven radius roller 172 and the vicinity of the lower end of the bridge eliminating plate 190 changes, and the bridge eliminating plate 1 is rotated.
90 is reciprocated, thereby causing the eraser 56
Is moved to eliminate the bridge.

When the eraser 56 in the eraser storage chamber 54 decreases and the light receiver 214 of the eraser decrease detecting device 210 receives the light emitted from the light emitter 212 and the decrease of the eraser 56 is detected, the alarm 264 is output. Is notified to the installer of the eraser dispenser. Cover 1 accordingly
4 is opened, and the eraser storage chamber 54 is refilled with the eraser 56.

In the present dispensing device, the eraser 56 can be dispensed manually. For example, when the eraser 56 is stuck between the dispensing member 60 and the rotating wall member 116 and the eraser 56 is not dispensed no matter how much the dispensing member 60 is rotated, the replacement of the eraser 56 in the eraser storage chamber 54 is performed. When performing the operation, the manual operation member 16 shown in FIG.
2 is operated. The operated part 166 of the manual operation member 162
To move the manual operation member 162 to the cover 14 side, and thereby the engaging portion 1 of the manual operation member 162 is moved.
68 is engaged with the rotating wall member 116, and the facing surface 138 is rotated in a direction away from the dispensing member 60, and the eraser 56 is rotated.
Falls. If a single operation of the manual operation member 162 is not enough, the manual operation member 162 is reciprocated a plurality of times, and the eraser 56 is rotated by the rotation of the rotating wall member 116 and the vibration of the entire apparatus. Drops reliably. After the eraser 56 is dropped, if the manual operation member 162 is returned to the original position, that is, the position where the operated portion 166 is engaged with the front bracket 164 as shown in FIG. Is returned to the original position, and the eraser 56 does not fall.

In the above embodiment, the dispensing member 60 is used.
Is a dispensing member driving device 96 using a driving motor 94 as a driving source.
, And the eraser 56 is automatically paid out, but the payout rotating body may be rotated manually. In this case, if it is inconvenient that the dispensing member 60 can rotate indefinitely, a device that allows the dispensing member 60 to rotate only at a limited angle may be provided. For example, an engaging member is attached to the frame so as to be movable in a direction parallel to the rotation axis of the dispensing rotator, and protrudes into the turning trajectory of a turning member such as a dispensing claw to engage with the turning member, and to engage the turning member. An actuator such as a solenoid is used to move between an engagement position where rotation is prevented and a retracted position where engagement and rotation of the dispensing rotator are permitted without being engaged. The engaging member is moved to the retreat position in response to the payout permission signal from the game machine, and the payout of one eraser 56 is detected by the payout detecting device 230, or the rotation of the payout member at a predetermined angle is detected by the rotation detector. When the detection is performed by the control unit, it is made to return to the engagement position.

Further, in the above embodiment, the eraser payout device is a portion for paying out the eraser as a prize of the game machine, but it can be used as an eraser payout device for an eraser vending machine. In this case, instead of the game machine 262, for example, a price input detector for detecting the input of the price is provided, and this constitutes the payout instruction means. Alternatively, it can be configured in various modes such as including a payout instruction button and a lever for instructing the payout of the eraser, in addition to the money input device. When the dispensing member is manually rotated, the rotation of the dispensing member is allowed based on permission of the dispensing by the dispensing permitting means.

Further, in the above embodiment, the dispensing member 6
The dispensing of the eraser 56 by 0 is controlled by the control device 260 mainly composed of a computer, but it is also possible to replace the computer with a dedicated electronic circuit. Further, the present invention is particularly effective when applied to an apparatus for dispensing a columnar material to be discharged such as a regular hexagonal prism, a regular square prism, a cylinder, or the like. The present invention can also be applied to a dispensing device that dispenses dispensing materials. In addition, without departing from the scope of the claims, the present invention can be implemented in various modified and improved forms based on the knowledge of those skilled in the art.
