Description

  The present invention relates to a technique for separating and feeding out media one by one from a media bundle.

  Public competition is a professional sport held as gambling. The applicant can purchase a voting ticket by predicting the race result, that is, the order of arrival of the competitors (including horses on which the riders who are competitors are riding) for each ceremony.

  At public stadiums and polling stations, voting ticket issuing devices (including voting ticket issuing devices here) are installed so that voting tickets can be purchased automatically. The voting ticket issuing device reads a voting card inserted by a purchase applicant, and issues a voting ticket with voting contents designated by the voting card. Currently, most of the voting ticket issuing devices can insert a plurality of voting cards at a time so that voting tickets desired by purchasers can be purchased more efficiently. Since one or more stacked voting cards are inserted into the voting ticket issuing apparatus, hereinafter, the inserted one or more voting cards will be referred to as “voting card bundle” for convenience.

  The voting card bundle inserted by the purchase applicant is fed and conveyed one by one for reading. For this reason, the betting ticket issuing device is equipped with a medium feeding device for feeding a voting card.

  The medium feeding device temporarily transmits a conveying force by a pick roller which is a feeding roller to a voting card in a voting card bundle. By temporarily transmitting the conveying force, one voting card is separated from the voting card bundle and conveyed.

  The manufacturing cost of the device tends to increase as the number of parts increases. Therefore, in the betting ticket issuing device equipped with the medium feeding device, the number of motors serving as power sources is reduced. As a result, the number of medium feeding devices that use a motor used for conveying the voting card as a power source for feeding the voting card is increasing.

  The position at which the pick-up card bundle transmits the pick roller transport force is the end on the back side in the vote card transport direction. For this reason, if the voting card whose conveying force should be transmitted to the pick roller is shifted to the front side (here, the insertion direction side) in the conveying direction, the conveying force cannot be properly transmitted to the voting card. Next, when there is a voting card to which the conveying force is to be transmitted, the conveying force is transmitted to the voting card, and a payout error in which two or more voting cards are drawn out easily occurs.

  Generally, a mechanism for temporarily transmitting power from a motor to a pick roller is mounted on a medium feeding device that uses a motor used for conveying a voting card as a power source for feeding voting cards. A gear is generally used for power transmission.

  In the temporary transmission of power using gears, the gears are temporarily engaged with each other. When the gears are engaged with each other, depending on the positional relationship of the teeth of the gears to be engaged, there is a possibility that the gear on the side to which power is transmitted rotates momentarily in the direction opposite to the assumed direction.

  The gear on the side to which power is transmitted is connected to the pick roller. Therefore, when the gear on the side to which power is transmitted rotates in the opposite direction to the assumed direction, the pick roller applies a conveying force in a direction opposite to the direction in which the voting card is drawn out. However, when a conveying force is applied in the opposite direction, a feeding error is likely to occur due to the positional relationship between the pick roller and the voting card bundle. For this reason, a one-way clutch that is a mechanism for rotating the pick roller in only one direction is currently employed.

  One-way clutches do not function properly due to dust, dirt, etc., and therefore require regular maintenance such as cleaning. Since the voting card is fed and transported, the medium feeding device is an environment in which dust (paper dust) is likely to be generated. For this reason, cleaning of the one-way clutch is an essential item in periodic maintenance of the medium feeding device.

  The cleaning of the one-way clutch needs to be performed by removing the structure including the one-way clutch from the medium feeding device and disassembling the removed structure. Therefore, it takes a long time to clean the one-way clutch, which increases the maintenance cost. Thereby, it seems important to further suppress the maintenance cost of the medium feeding device. This is a common problem as long as it is a medium feeding device that employs a one-way clutch to limit the rotation direction of the pick roller, regardless of the type of medium, and a device equipped with the medium feeding device. .

It is a figure explaining the hardware structural example of a voting card reading unit.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a voting card reading unit equipped with a medium feeding device according to the present embodiment.

  In this voting card reading unit 1, one or more voting cards in which voting contents are entered are inserted, and an overlapped voting card bundle is inserted into the batch insertion portion 2 from the direction indicated by the arrow in FIG. As a result, the voting card reading unit 1 feeds the voting cards one by one from the voting card bundle, conveys them, and reads the voting contents entered on the voting cards being conveyed. Reference numeral 3 denotes a payout mechanism for paying out the voting cards one by one from the voting card bundle.

  The voting card fed out by the feeding mechanism 3 is read in the middle of being conveyed toward the stacker unit 4 for storing the voting card. The voting card for which the voting content cannot be read properly and the voting card for which the voting content is inappropriate are discharged from the return port 6 via the return unit 5.

  FIG. 2 is a perspective view showing details of the feeding mechanism. The feeding mechanism 3 will be described in more detail with reference to FIG.

  The return unit 5 can be opened and closed, and FIG. 2 shows the feeding mechanism 3 with the return unit 5 opened. 2A is a perspective view from the upper right side (viewed from the arrow C in FIG. 1), and FIG. 2B is a perspective view from the upper left side. It is a figure (figure seen from the arrow D of FIG. 1). Hereinafter, unless otherwise specified, a viewpoint viewed from the direction of the arrow shown in FIG. 1 is assumed.

  The voting card reading unit 1 is equipped with only one motor 41 as a power source for feeding out the voting card and transporting the voting card. A pulley 42 is attached to the shaft of the motor 41. The pulley 42 transmits power to the belt 43. The belt 43 is stretched between the pulley 42, the plurality of pulleys 45, and the pulley 46.

  A shaft 47 to which the pulley 46 is attached supports the gear 21. A gear 22 is meshed with the gear 21, and a gear 34 is meshed with the gear 22. Thereby, the power transmitted from the motor 41 to the pulley 46 is transmitted to the gear 34 via the shaft 47, the gear 21, and the gear 22.

  The gear 34 is a part of the structure 30 for paying out a voting card. As shown in FIG. 3, the structure 30 has a configuration in which a pick roller 32, gears 33 and 34, and a bearing 38 are attached to a shaft 31.

  The shaft 31 is provided with parallel pins 36 protruding in the radial direction. The pick roller 32 is formed with a hole 32a into which the shaft 31 can be inserted, and two grooves 32b that protrude in the radial direction from the hole 32a and into which the inserted parallel pin 36 can move.

FIG. 3 is an exploded perspective view of the structure 30.
As shown in FIG. 3, the gear 34 meshed with the gear 22 has a hole 34a into which the shaft 31 is inserted. Thereby, the gear 34 is rotatably supported with respect to the shaft 31. Therefore, hereinafter, the gear 34 is also referred to as an idler gear.

  On the other hand, like the pick roller 32, the gear 33 is formed with a hole 33a into which the shaft 31 is inserted, and two grooves 33b that protrude in the radial direction from the hole 33a and into which the inserted parallel pin 36 can move. Yes.

  The gear 23 is temporarily meshed with the two gears 33 and 34. Due to the meshing of the gear 23, the power from the motor 41 is transmitted to the shaft 31, and the shaft 31 rotates. Along with the rotation, the pick roller 32 rotates, and the power from the pick roller 32 is transmitted to the voting card located at the top of the voting card bundle. As a result, one voting card is paid out.

  As shown in FIGS. 2A and 2B, the temporary engagement between the gear 23 and the gears 33 and 34 is performed using a solenoid 25. The gear 23 is supported by a shaft 29 attached to a bracket 28, and power from a plunger 35 a of a solenoid 35 is transmitted to the bracket 28 via a connecting member 26. The connecting member 26 and the bracket 28 are connected by a shaft 27. Thereby, only when the solenoid 35 is driven, the gear 23 is pressed against the gears 33 and 34.

  Next, the operation of the feeding mechanism 3 will be specifically described with reference to FIGS. FIG. 4 is a top view of the feeding mechanism. FIGS. 5A and 5B are diagrams for explaining the state of the payout function when the voting card is not drawn, in which FIG. 5A is a cross-sectional view taken along the line AA during non-drawing, and FIG. FIG. 6A and 6B are diagrams for explaining the state when the voting card is paid out. FIG. 6A is a cross-sectional view taken along the line AA during the payout, and FIG. 5B is a cross-sectional view taken along the line BB during the payout. is there. In FIGS. 4 to 6, only main components are particularly shown for convenience.

  As shown in FIG. 4, the gear 23 is a gear having a width that can be meshed with the two gears 33 and 34. Therefore, when the gear 23 is engaged with the two gears 33 and 34, the power transmitted to the gear 34 is transmitted to the gear 33 via the gear 23. By transmitting power to the gear 33, power is transmitted to the pick roller 32 through the shaft 31, and the pick roller 32 feeds the voting card positioned at the top of the voting card bundle 60.

  As shown in FIGS. 5A and 6A, the bracket 28 to which the gear 23 is attached is rotatable about the shaft 51. The other end 28a of the bracket 28 is for power transmission to the pressure plate 54 shown in FIGS. 5B and 6B. The pressure plate 54 is a member for pressing the voting card bundle 60 toward the pick roller 32, and power is transmitted through the shaft 52 attached to the end portion 28 a of the bracket 28. Reference numeral 53 denotes an upper plate that guides the conveyance of the voting card bundle 60, and reference numeral 55 denotes a roller (pinch roller) for conveying the voting card bundle 60 inserted into the batch insertion portion 2 to the back side.

  As described above, when not extended, the solenoid 25 is not driven, and the gear 23 is separated from the gears 33 and 34 as shown in FIG. As shown in FIG. 5B, the pressure plate 54 is not in a state of pressing the voting card bundle 60 toward the pick roller 32.

  On the other hand, at the time of delivery, the solenoid 25 is driven, and the gear 23 moves toward the gears 33 and 34 and meshes as shown in FIG. The pressure plate 54 is in a state of pressing the voting card bundle 60 toward the pick roller 32 as shown in FIG.

  In a state where the pressure plate 54 presses the voting card bundle 60 against the pick roller 32, the voting card bundle 60 is sandwiched between the transport roller 56 and the pinch roller 55 as shown in FIG. The transport roller 56 is provided to transport the voting card bundle 60 to the back when the voting cart bundle 60 is inserted into the batch insertion portion 2. Thereby, the conveyance force by the conveyance roller 56 acts on the uppermost voting card of the voting card bundle 60 even at the time of feeding.

  At the time of feeding, the gear 23 is engaged with the gears 33 and 34. During the meshing, the gear 33 rotates in either the forward or reverse direction depending on the positional relationship between its own teeth and the teeth of the gear 23. Here, the positive direction is the direction in which the voting card is drawn out (the clockwise direction toward FIG. 5A). Therefore, the reverse direction is a direction in which the conveying force is applied with the voting card directed toward the batch insertion portion 2 side.

  When both the gear 33 and the pick roller 32 are fixedly attached to the shaft 31, the shaft 31 and the pick roller 32 rotate in a manner interlocking with the gear 33 in the same direction. For this reason, when the gear 33 rotates in the reverse direction when the gear 23 is engaged, the pick roller 32 attached to the shaft 31 moves toward the batch insertion portion 2 with respect to the voting card in contact with the voting card bundle 60. The conveyance force to be conveyed is applied. When such a conveying force is applied, the voting card and the pick roller 32 that are applied with the conveying force are not in contact with each other, or the contact range is narrowed, and there is a high possibility that the voting card to be paid out cannot be properly drawn out. . For this reason, conventionally, one-way clutches for rotating only in the forward direction are widely used for limiting the rotation direction of the pick roller 32.

  When employing a one-way clutch, the shaft 31 is required to have high hardness, high accuracy, and the like. The number of parts also increases. For this reason, the use of a one-way clutch increases the manufacturing cost.

  In addition, the one-way clutch does not function properly due to dust, dirt, and the like. When the voting card is fed out and transported, dust (paper dust) is likely to be generated, so the one-way clutch must be cleaned by regular maintenance. Since it takes a long time to clean the one-way clutch, the maintenance cost is also very high.

  For this reason, in the present embodiment, the groove 32b is provided in the pick roller 32 and the groove 33b is provided in the gear 33, thereby suppressing the need to employ a one-way clutch.

  Both the groove 32b provided in the pick roller 32 and the groove 33b provided in the gear 33 make a margin until the pick roller 32 rotates in the reverse direction. As long as power is transmitted from the gear 33 to the shaft 31, the parallel pin 36 contacts one of the two surfaces 32b1 and 32b2 of the groove 32b, and the parallel pin 37 contacts the two surfaces 33b1 and 33b2 of the groove 33b. This is because the pick roller 32 does not rotate unless it contacts the surface on the same side. The maximum rotation angle for reversely rotating the gear 33 when the gear 23 is engaged is relatively small, and the grooves 32b and 33b are formed so that the parallel pins 36 and 37 can move more than the maximum rotation angle. ing. Therefore, when the gear 23 is engaged, the pick roller 32 does not reversely rotate, or even if it reversely rotates, the amount of rotation is small.

  For this reason, the need to use a one-way clutch can be virtually avoided. By not using the one-way clutch, both the manufacturing cost and the maintenance cost can be further suppressed. In addition, the configuration of the driving means such as gears, shafts, pulleys, and belts of the present embodiment enables the voting card (medium) to be fed out and transported with only one motor, thereby reducing manufacturing costs and maintenance costs. Both can be further suppressed.

  In the present embodiment, both the gear 33 and the pick roller 32 are provided with a rotatable range for suppressing the influence of the meshing of the gear 23, but only one of them is provided with a rotatable range. Also good. Further, a force may be applied so that the parallel pin 36 contacts the surface 32b2 of the groove 32b or the parallel pin 37 contacts the surface 33b2 of the groove 33b. When such a force is applied to either one, the reverse rotation of the pick roller 32 that occurs when the gear 23 is engaged can be surely avoided.
