Description

  The present invention is an apparatus for feeding out a disk-shaped body such as coins as currency or substitute money (medals, tokens, etc.) used in gaming facilities one by one. Specifically, the disk-shaped body is rotated. A rotary transfer body that transfers along the transfer path, and a disk-shaped body that has been transferred by the rotary transfer body, toward a delivery outlet formed on the outer side in the rotational radial direction at a set delivery site of the rotary transfer path The present invention relates to a disk-like body feeding device provided with a passage sensor provided with a passage sensing body that is displaced in contact with a delivery means that sends out and a disk-like body that is delivered by the delivery means.

  In the conventional disk-shaped body feeding device, the passage sensing body of the passage sensor is composed of a rocking sensing arm that rocks and displaces in contact with the disk-shaped body to be sent out. A return spring is provided that oscillates and oscillates from the passage sensing position to the sensing standby position after passing through the disk-like body, and the rotation is linked to an operation outside the setting of the oscillation sensing arm to the passage sensing position. A rotation preventing means for forcibly stopping the driving rotation of the transfer body is provided.

  As shown in Patent Document 1 below, the rotation preventing means is more than a plurality of through-holes into which disk-like bodies formed at a predetermined pitch along the rotation transfer path can enter the back surface of the rotation transfer body. A locked portion that protrudes downward on the line segment connecting the rotation axis of the rotary transfer body and the upper edge of the through hole in the rotation direction (rear side of rotation) inside the rotation radius. In addition, the swing detection arm protrudes into the rotation path of the locked portion and comes into contact with the locked portion from the rotation direction when the swing detection arm swings to the passage detection position. A locking member having a stop surface is integrally formed.

  Then, when the disk-like body is sent out toward the delivery port portion by the driving rotation of the rotary transfer body based on the payout command, one piece of the swing sensing arm is displaced by the contact with the disk-like body. When the passage sensor detects that the disk-shaped body has been delivered, and the number of detected sheets reaches the dispensing command number, the drive rotation of the rotary transfer body is stopped and the dispensing of the disk-shaped body is terminated.

  If the swing sensor arm of the passage sensor is forcibly swung to the passage detection position by any unauthorized means at the time of the payout and is maintained in this state, the passage sensor is in the detecting operation. In order to continue outputting the signal, the rotary transfer body continues to drive and rotate, and the disk-shaped body exceeding the number of payout commands is paid out.

  At this time, the continuous rotation of the rotary transfer body is forcibly stopped by the rotation preventing means interlocked with the non-setting operation to the passage detection position of the swing sensing arm due to the above-mentioned fraudulent action, and the subsequent circle by the illegal means is Discharge of the plate-like body is prevented.

JP 2004-157734 A

  In the conventional disk-shaped body feeding device, when the swing detection arm of the passage sensor is forcibly swung to the passage detection position by any unauthorized means and this state is maintained, this swing is performed. The locking surface of the locking member that is displaced integrally with the sensing arm continues to protrude into the rotation path of the locked portion provided in the rotary transfer body, and the locking surface of the locking member and the locked portion Since the drive rotation of the rotary transfer body is forcibly stopped by the engagement, a large impact force acts on the swing sensing arm and the swing pivot of the swing sensing arm, and the deformation of the swing sensing arm and the swing pivot.・ It may cause damage.

  In addition, among the back surface of the rotary transfer body, the locked portion is located at a position radially inward of the plurality of through holes into which the disk-like bodies formed at a predetermined pitch along the rotary transfer path can enter. Therefore, it is necessary to swing the locking member of the swing sensing arm toward the center of rotation at a position below the rotational transfer path of the disk-like body. There is an inconvenience that the complexity and size of the feeding device is complicated and the maintenance and inspection work is complicated.

  The present invention has been made in view of the above-described actual situation, and its main problem is to simplify and reduce the size of the structure while reliably preventing the disk-like body from being discharged due to fraud. It is in providing a discoid body feeding device that can be used.

In the present invention , the rotary transfer body that transfers the disk-shaped body along the rotary transfer path, and the disk-shaped body that has been transferred by the rotary transfer path at the outer side in the rotational radial direction at the set delivery site of the rotary transfer path A circle provided with a passage sensor provided with a passage sensing body that is displaced in contact with the delivery means that is sent out toward the delivery outlet formed on the disk and the disk-like body delivered by the delivery means in the plate-like body feeding device,
The passage sensing body, and a rotation sensing member rotates with the contact between the disc-shaped body.

  According to the above configuration, in the case of the conventional swing-type swing detection arm, it is necessary to always return and bias the swing detection arm at the passage detection position to the detection standby position after passing the disk-shaped body. For this reason, there has been a gap for the fraudulent act that the swing detection arm is maintained at the passage detection position by an unauthorized operation. However, in the present invention, the passage sensor is a disk-like shape that is sent out by the sending means. Since it is composed of a rotation sensing body that rotates in contact with the body, the rotation sensing body must be rotated in order to pay out the disk-like body. Even if the counterclockwise operation is forcibly performed by such illegal means, the disk-shaped body is only counted without being paid out, and there is no profit obtained by the illegal operation.

  In addition, since it is only necessary to change the passage sensing body to a rotation sensing body, a large impact is applied to the members and support parts constituting the passage sensor, as in the conventional device forcibly stopping the rotational transfer body being driven and rotated. The force does not act, the load acting on the passing sensor and the reverse rotation preventing means can be reduced, and the passing sensor structure can be simplified.

  Therefore, the rational improvement of rotating the passage sensing body only in one direction corresponding to the feeding direction of the disk-shaped body, and the simplification of the structure while reliably preventing the disk-shaped body from being discharged by fraud -Miniaturization can be achieved.

In the present invention, the reverse rotation preventing means for preventing the reverse rotation of the rotation sensing body is provided.

  According to the above configuration, the rotary transfer body temporarily reversely rotates due to an overload or the like acting on the electric motor while the disk-shaped body is being sent out while rotating the rotation sensing body, and the circular motion is caused by the influence. Even if the plate-like body moves backward and the rotation sensing body tries to reversely rotate, the reverse rotation of the rotation sensing body can be prevented by the reverse rotation preventing means. Measurement errors caused can be suppressed.

In the present invention, the rotational position holding means is provided for position holding the center angle units corresponding to the rotation sensing body passage moving range of the disc-shaped body.

  According to the above configuration, while the rotation sensing body is rotated by using the feeding force of the disk-shaped body, the position of the rotation sensing body is held in units of a central angle corresponding to the passing movement range of the disk-shaped body. Thus, the rotation sensing body can be reliably held in a predetermined sensing standby state.

In the present invention, the passage sensor has been assembled with the detachable unit case relative to the base for supporting the rotary transfer member.

  According to the said structure, the maintenance / inspection operation | work with respect to the said passage center can be easily performed in the large space outside a disk-shaped object feeding apparatus by taking out a unit case from the said base.

In the present invention , a contact portion that is in contact with the disk-shaped body that is fed out is formed at a plurality of locations in the circumferential direction of the rotation sensing body, and between the adjacent contact portions, one of the corresponding portions. A receiving portion that receives at least a part of the bottom surface of the disk-shaped body that passes and moves in contact is provided in a state that is flush with or substantially flush with the delivery guide surface of the delivery port portion.

  According to the above configuration, at least a part of the bottom surface of the disk-shaped body that passes and moves in contact with the contact portion of the rotation sensing body is received by the receiving portion provided between the contact portions. Thus, even when the rotation axis of the rotation sensing body is shaken by vibration or load, the relative positional relationship between the contact portion and the disk-shaped body is difficult to change, and the disk-shaped body is not slipped through. It is possible to reliably guide the passage.

In the present invention , the reverse rotation preventing means includes an engaged portion provided on the rotation sensing member, a reverse rotation restricting position protruding into the rotational movement path of the engaged portion, and the rotational movement path outside the engaged portion. A rotation restricting member movable to the restriction release position retracted, an urging member for urging the rotation restricting member to move to the reverse rotation restricting position, and the rotation sensing member in contact with the disk-like member when forward rotation regulation release means for moving the rotation restricting member to the restriction release position against the biasing force of the biasing member is provided.

  According to the above configuration, when a normal disk-like body is paid out, the rotation sensing body is provided on the rotation sensing body when the rotation sensing body rotates in the forward direction in contact with the disk-like body sent out by the sending means. The rotation restricting member at the reverse rotation restricting position protruding into the rotation movement path of the engaged portion is moved to the restriction releasing position against the urging force of the urging member by the restriction releasing means. The disc-shaped body is paid out reliably and smoothly by forward rotation.

  Further, even when the rotation sensing body is operated to rotate forward due to fraud, since the rotation sensing body continues to rotate normally in the same manner as described above, it is counted without the disk-shaped body being dispensed. , There is no profit gained from cheating.

  Further, when the rotation sensing body is reversely rotated by an improper act, the restriction release means does not work and the engaged portion provided on the rotation sensing body engages with the rotation regulating member at the reverse rotation regulating position. Thus, reverse rotation of the rotation detector is prevented.

  Accordingly, it is possible to simplify and downsize the reverse rotation preventing structure while reliably preventing the disc-like body from being discharged due to fraud.

In the present invention , the rotation position holding means is engaged with a plurality of arc-shaped recesses formed on the rotation shaft of the rotation sensing unit in a central angle unit corresponding to the passing movement range of the disk-shaped body, and the arc-shaped recesses. an arm having a possible rollers, urging body for urging the arm to the engagement side is provided.

According to the above configuration, when the disk-shaped body passes while pressing and rotating the rotation sensing body, the roller of the arm receiving the urging force of the urging body passes over the arc-shaped recess and rapidly reaches the next arc-shaped recess. Therefore, the angular velocity of the rotation sensing body is instantaneously increased, so that the feeding action of the disk-shaped body can be made smooth and reliable.

  Between the opposing surfaces of the rotation sensing body 32 and the detection rotating body 35, the rotational force of the rotation sensing body 32 that is pressed and rotated by the disc-like body 1 by being engaged from above and below is transmitted to the detection rotating body 35. The rotation transmitting teeth 36 and 37 are integrally formed.

  In this embodiment, the light-shielding portion 35a and the light-transmitting portions 35b of the detection rotating body 35 are formed three by three, and the rotation sensing body 32 is moved to 120 by one passing movement of the disk-shaped body 1 to be sent out. One pulse signal is output from the optical sensor unit 34 by one-third rotation of the detection rotator 35 that is rotated by a central angle unit of degrees, and rotates integrally with the detection rotator 35, and the number of dispensed disks 1 is counted as one. Is configured to do.

  Abutting portions 32B that come into contact with the disc-shaped body 1 to be fed out are integrally formed radially at a plurality of circumferential locations (three locations in the present embodiment) of the boss portion 32A of the rotation sensing body 32, and A receiving portion 32C that receives a part of the bottom surface of the disc-like body 1 that passes through and moves in a state of being in contact with one of the corresponding portions 32B is provided between the contact portions 32B.

  A part of the bottom surface of the disk-like body 1 that passes and moves in contact with the contact portion 32B of the rotation sensing body 32 is received by a receiving portion 32C provided between adjacent the contact portions 32B. Therefore, even when the rotation axis of the rotation sensing body 32 is shaken by vibration or load, the relative positional relationship between the contact portion 32B and the disk-like body 1 is difficult to change, and the disk-like body 1 is passed through. It is possible to guide the passage without fail.

  The reverse rotation preventing means D includes the contact portion 32B that also serves as an engaged portion provided in the rotation sensing body 32, and a reverse rotation restricting position and a contact portion that protrude into the rotational movement path of the contact portion 32B. A rotation restricting member 40 movable to a restriction release position retracted out of the rotational movement path of 32B, a coil spring 41 which is an example of an urging body for moving and energizing the rotation restricting member 40 to the reverse rotation restricting position, When the rotation sensing body 32 rotates forward with the contact with the disc-like body 1, a restriction release means 42 that moves the rotation restriction member 40 to the restriction release position against the elastic biasing force of the coil spring 41. Is provided.

  At one end of the rotation restricting member 40, a boss portion 40A pivotably mounted on a support shaft 44 in a lateral orientation is formed, and on the upper surface of the pedestal portion 26A of the upper case 26, A pair of U-shaped bearing projections 43 are formed integrally so as to horizontally detachably mount the bearing shaft 44 in the vertical direction.

  On the lower surface side of one end portion of the rotation restricting member 40, there is a plate-like engagement portion 40B that can project into the rotational movement path of the contact portion 32B through an opening 45 formed in the base portion 26A of the upper case 26. A spring receiving portion 46 that receives the lower end portion of the coil spring 41 is formed on the upper surface side of one end portion of the rotation restricting member 40.

  A mounting pin 47 inserted into the coil spring 41 is integrally formed at the center position of the spring receiving portion 46, and the removal movement of the coil spring 41 from the mounting pin 47 is prevented from being moved by the base portion of the upper case 26. It is configured to be blocked by the inner surface of the upper cover 27 that is detachably attached to 26A.

  Of the corners 32a and 32b on both sides in the rotation direction of each contact portion 32B of the rotation sensing body 32, the engagement portion 40B is formed at one end of the rotation restricting member 40 when the rotation sensing body 32 rotates in the reverse direction. The first corner portions 32a to be joined are formed at right angles, and an engagement surface that reliably engages with the engagement portion 40B of the rotation restricting member 40 is formed on one side surface of each contact portion 32B. The second corner portion 32b that engages with the engaging portion 40B of the rotation restricting member 40 during the forward rotation of the rotation restricting the engaging portion 40B of the rotation restricting member 40 against the elastic biasing force of the coil spring 41. The restriction release means 42 is formed by a second arcuate portion 32b that is formed into a large arcuate surface that can be lifted and swung.

  When the disc-shaped body 1 is paid out normally, when the rotation sensing body 32 rotates in the forward direction in contact with the disc-shaped body 1 sent out by the sending means B, the rotation sensing body 32 hits. The engaging portion 40B of the rotation restricting member 40 at the reverse rotation restricting position protruding into the rotational movement path of the portion 32B (also serving as the engaged portion) is formed by the arcuate second corner portion 32b constituting the restriction releasing means. Since the coil spring 41 is forcibly moved to the restriction release position against the elastic biasing force of the coil spring 41, the disc-like body 1 is reliably and smoothly delivered by the normal rotation of the rotation sensing body 32.

  Further, even when the rotation sensing body 32 is operated to rotate forward due to an illegal act, the rotation sensing body 32 continues to rotate normally in the same manner as described above. Therefore, the counting is performed without the disk-shaped body 1 being dispensed. And there is no benefit from fraud.

  Further, while the disk-like body 1 is being sent out while rotating the rotation sensing body 32, the rotary transfer body 8 temporarily reversely rotates due to an overload or the like acting on the electric motor 3, and as a result, the circular shape is affected. Even if the plate-like body 1 moves backward and the rotation sensing body 32 tries to reversely rotate, the arcuate second corner portion 32b constituting the restriction release means does not work, and is a right angle located on the opposite side. The first corner portion 32a engages with the engaging portion 40B of the rotation restricting member 40 at the reverse rotation restricting position, and the reverse rotation of the rotation sensing member 32 is surely prevented. Measurement errors due to reverse rotation can be suppressed.

  The rotational position holding means E includes an outer peripheral surface of the boss portion 35A of the detection rotating body 35 and a rotational axis side of the rotation sensing body 32 within a central angle range corresponding to a passing movement range of the disk-like body 1.
