DETAILED DESCRIPTION OF THE EMBODIMENTS

(9) The embodiments of the lottery ticket dispensing device according to the invention will be described in detail below in conjunction with the drawings. Schematic diagrams of the lottery ticket dispensing device according to the invention are shown in the drawings. It should be noted that, the drawings and the embodiments described below are examples only, rather than limiting the invention.

(10) As shown in FIGS. 1-7, the lottery ticket dispensing device according to the invention is generally referred to as 10, and such a lottery ticket dispensing device 10, mounted on an automatic lottery ticket vending machine, may be used for automatically dispensing scratch-off lottery tickets, i.e., a continuous lottery ticket tape 16 set with penetrative parting lines thereon.

(11) As shown in FIG. 1, the lottery ticket dispensing device 10 includes a housing, which is formed of a pair of support plates 12 that are spaced apart oppositely and arranged in parallel. The housing is used to accommodate and support various devices mounted thereon. Each support plate 12 is formed with at least one flange 13 that extends along the lateral part of the support plate, and the flange 13 may be connected to the rack of an automatic lottery ticket vending machine via a bolt or the like, thereby the lottery ticket dispensing device may be mounted to the automatic lottery ticket vending machine. The housing is set with a planar ticket feed guide plate 14, which extends between two support plates 12 and is connected with the two support plates 12. A ticket feed bearing plate 15 is set under the ticket feed guide plate 14, and the ticket feed bearing plate 15 is spaced apart from the ticket feed guide plate 14 and is substantially parallel to the ticket feed guide plate 14, thereby a ticket feeding port for inserting a lottery ticket tape 16 is formed between the ticket feed guide plate 14 and the ticket feed bearing plate 15.

(12) The lottery ticket tape 16 is driven by a lottery ticket feeding device to dispense lottery tickets. The lottery ticket feeding device includes a drive motor 22, a first drive roller 18 and a driven roller 20. The drive motor 22 is mounted on a support plate 12 and has a certain distance from the ticket feed guide plate 14. The drive motor 22 may include a step motor, a servo motor or an electrical motor of other types. The first drive roller 18 and the driven roller 20 are mounted on the support plate 12 via a pair of shaft liners (not shown) and extend between two support plates 12. The first drive roller 18 and the driven roller 20 are mounted in such a way that they are rotatable and are pressed against each other, and the lottery ticket tape 16 is allowed to pass therebetween. Therefore, a spring 21a may be set respectively on the two ends of the shaft 20a of the driven roller 20 along the radial direction for pressing the driven roller 20 against the first drive roller 18. As shown in FIG. 2, the shaft liner related to the driven roller 20 matches the spring 21a that is set in a corresponding opening 21b formed on the support plate 12, thereby, the shaft 20a of the driven roller 20 may still rotate in the corresponding shaft liner when pressed by the spring 21a. The first drive roller 18 may have the similar settings, although it is not shown in the figure.

(13) The operation of the drive motor 22 is controlled by a control device 23. For example, the control device 23 is a printed circuit driven by a computer, or other known types of drives or control circuits connected with appropriate driving input devices. As shown in FIG. 1, if the drive motor 22 operates under the control of the control device 23, an electrical motor output shaft 24 rotates along arrow direction A, then a drive gear 26 mounted on the electrical motor output shaft 24 also rotates along arrow direction A. The drive gear 26 is engaged with a transfer gear 28 and drives the transfer gear 28 to rotate along arrow direction B. The transfer gear 28 is engaged with a first drive roller gear 18c that is connected with one end of the first drive roller shaft 18a, and it drives the first drive roller gear 18c and the first drive roller shaft 18a to rotate along arrow direction A, thereby the first drive roller 18 is made to rotate along arrow direction A. Because the driven roller 20 is pressed against the external surface of the first drive roller 18, it rotates along a direction that is opposite to that of the first drive roller 18 as driven by the first drive roller 18.

(14) As shown in FIG. 5, the lottery ticket dispensing device 10 further includes a cutter 36, which is detachably mounted on a cutter mounting plate 37. The cutter mounting plate 37 is set between two support plates 12 and is perpendicular to the support plate 12, and it is adjacent to the first drive roller 18 and the driven roller 20. A ticket guiding device 39 is set on the cutter mounting plate 37, and the ticket guiding device 39 has a guide surface 39′(see FIG. 6); the guide surface 39′ of the ticket guiding device 39 is aligned with the upper surface of the cutter 36, and the guide surface 39′ extends toward the first drive roller 18. Thereby, the front edge of the lottery ticket tape 16, which has passed through the first drive roller 18 and the driven roller 20, contacts the guide surface of the ticket guiding device 39 and is guided to the upper surface of the cutter 36, rather than being blocked in the gap between the cutter 36 and the first drive roller 18.

(15) As shown in FIG. 1 and FIG. 5, a second drive roller 40 is set behind the first drive roller 18 and the driven roller 20 along the feeding direction of the lottery ticket tape 16. The second drive roller gear 40c and the first drive roller gear 18c are mounted on the same side of the same support plate 12, and the first drive roller gear 18c is engaged with the second drive roller gear 40c. The rotation of the first drive roller gear 18c drives the second drive roller gear 40c to rotate along direction B (see FIG. 1), thereby the second drive roller 40 rotates in the clockwise direction in FIG. 5 for feeding the lottery ticket tape 16 in the ticket dispensing direction.

(16) As shown in FIG. 5, a guiding press plate 38 for bending the lottery ticket tape 16 is rotatably mounted on the second drive roller shaft 40a and extends between the support plates 12. Although the guiding press plate 38 is also mounted on the second drive roller shaft 40a, the rotation of the guiding press plate 38 is independent of the second drive roller 40; in other words, the guiding press plate 38 is only supported on the second drive roller shaft 40a, but it will not rotate along with the rotation of the second drive roller 40, and the rotation of the guiding press plate 38 is controlled by a guiding press plate drive device that will be described below.

(17) As shown in FIGS. 2, 3, 4, 6, the lottery ticket dispensing device according to the invention includes a guiding press plate drive device, which may be mounted on one side of a support plate 12 and be opposite to the first drive roller gear 18c and the second drive roller gear 40c. The guiding press plate drive device includes a linear electromagnet 50, a lever 51, a pulling plate 52 and a spring 53. The linear electromagnet 50 is fixed on the outside of the support plate 12 of the housing. The linear electromagnet 50 includes a push rod, which contacts the first end of the lever 51 (the end part of the short arm in FIG. 2). The lever 51 is rotatably mounted on the housing. As shown in FIG. 2, the rotation axis of the lever 51 and the second drive roller shaft 40a are coaxial; however, the rotation of the lever 51 is independent of the second drive roller 40. The second end of the lever 51 (the end part of the long arm in FIG. 2) is rotatably connected with the first end of pulling plate 52. As shown in FIG. 3, the second end of the pulling plate 52 is rotatably connected with the guiding press plate 38. The lever 51 includes a supporting point, which is rotatably supported on the support plate 12 of the housing. The first end of the spring 53 is fixed on the support plate of the housing, and the second end of the spring 53 is connected at a position between the first end and the second end of pulling plate 52. Preferably, the spring 53 is a tension spring.

(18) As shown in FIG. 5, the lottery ticket dispensing device according to the invention further includes a first sensor (also called lottery ticket inputting sensor) 43 and a second sensor (also called transmitting and loading sensor) 44, for providing feedback information about the position of the continuous lottery ticket tape 16 to the control device 23. The first sensor 43 is mounted in front of the first drive roller 18 and the driven roller 20 along the lottery ticket feeding path, and the second sensor 44 is mounted behind the first drive roller 18 and the driven roller 20 and in front of the second drive roller 40 along the lottery ticket feeding path. In the embodiment shown in FIG. 5, the second sensor 44 is opposite to the ticket guiding device 39 above the cutter mounting plate 37. The first sensor 43 is used to detect whether the lottery ticket tape 16 is inserted in the ticket feeding port, and once it detects that the lottery ticket tape 16 is inserted, the drive motor 22 starts to drive the first drive roller 18 to rotate for feeding and loading the lottery ticket tape 16 in the ticket dispensing direction. The second sensor 44 is used to detect whether the lottery ticket tape 16 is loaded, that is, to detect whether the front edge of the lottery ticket tape 16 has passed between the first drive roller 18 and the driven roller 20.

(19) As shown in FIG. 3, the lottery ticket dispensing device according to the invention further includes a control device 23. The signal lines of the drive motor 22, the linear electromagnet 50, the first sensor 43 and the second sensor 44 are all connected to the control device 23. The control device 23 controls the rotation direction and rotation time of the drive motor 22, thereby controlling the forward and backward movement of the lottery ticket tape 16 and the feed length of the lottery ticket tape 16. The control device 23 receives a detection signal from the first sensor 43 and the second sensor 44. The control device 23 further controls the driving and releasing of the linear electromagnet 50.

(20) The operation by which the lottery ticket dispensing device 10 dispenses the continuous lottery ticket tape 16 will be described below.

(21) A forward feed distance of the lottery ticket tape 16, i.e., the length of a certain scratch-off lottery ticket sold by the lottery ticket dispensing device 10, is preset, which may be stored in the control device 23 and controlled by the control device 23.

(22) A lottery ticket tape is loaded. Specifically, a continuous lottery ticket tape 16 is output from a storage box (not shown) or other storage device, and it is manually or automatically inserted in a ticket feeding port formed between the ticket feed guide plate 14 and the ticket feed bearing plate 15. Once the first sensor 43 detects that the lottery ticket tape 16 is inserted in the ticket feeding port, it sends a signal to the control device 23. The control device 23 starts to drive the first drive roller 18 to rotate according to the signal received, and at the same time, it drives the second drive roller 40 to rotate together. The rotation of the first drive roller 18 feeds the lottery ticket tape 16 forward and makes it pass between the first drive roller 18 and the driven roller 20, then the lottery ticket tape 16 contacts the guide surface 39′ of the ticket guiding device 39, and it is fed forward successfully under the guide of the guide surface 39′ until the front edge of the lottery ticket tape 16 reaches the second sensor 44, thus the process of loading a lottery ticket tape is completed.

(23) A lottery ticket is dispensed (vending a lottery ticket). Specifically, after receiving an external drawing instruction, the front edge of the lottery ticket tape 16 advances a predetermined distance (for example, 20-40 mm, and preferably, 28 mm) from the second sensor 44, and this distance equals to the length of the scratch-off lottery ticket that is being vended plus 28 mm, and at this time, the control device 23 sends a signal to the drive motor to stop the driving of the drive motor 22. At the same time, the control device 23 sends a signal to the linear electromagnet 50 to start the action of bending the scratch-off lottery ticket to be distributed along a penetrative parting line of the lottery ticket tape 16.

(24) After the linear electromagnet 50 receives a signal from the control device 23, it propels the push rod to move forward linearly and push the first end of the lever 51, thereby propelling the lever 51 to rotate in the clockwise direction in FIG. 2. The second end of the lever 51 drives the pulling plate 52, which matches the second end of the lever 51, to also rotate in the clockwise direction in FIG. 2, thereby driving the guiding press plate 38, of which one end is rotatably connected with the pulling plate 52, to rotate in the clockwise direction (as shown in FIG. 3 and FIG. 4). The rotation of the guiding press plate 38 makes the scratch-off lottery ticket to be dispensed bend toward the direction of the cutter 36 (the anticlockwise direction in FIG. 5) along penetrative parting line of the lottery ticket tape 16, and makes the separating edge of the cutter 36 contact the penetrative parting line on the lottery ticket tape 16. At this time, the control device 23 sends a reverse rotation signal to the drive motor 22, and the drive motor 22 drives the first drive roller 18 and the second drive roller 40 to rotate reversely, thereby the lottery ticket tape 16 moves backward, and the scratch-off lottery ticket to be dispensed is cut off by the cutter 36 along the penetrative parting line that contacts the cutter 36, thus a lottery ticket is separated. At this time, the lottery ticket tape 16 continues to roll back, until the second sensor 44 transmits a signal to the control device 23 after detecting the position of the front edge of the lottery ticket tape 16, and the control device 23 transmits an instruction for stopping the drive motor 22; at this time, the front edge of the lottery ticket tape 16 stops at the position of the second sensor 44.

(25) After the lottery ticket is separated, the control device 23 sends a signal to the linear electromagnet 50, so that the push rod of the linear electromagnet 50 rolls back. At this time, the pulling plate 52 is drawn by the restoring force of the spring 53 to rotate in the anticlockwise direction in FIG. 2, so that the guiding press plate 38 connected with the pulling plate 52 also rotates in the anticlockwise direction and recovers the position for starting the next ticket cutting action.

(26) The lottery ticket dispensing device according to the invention may dispense a predetermined number of scratch-off lottery tickets automatically according to a user operation. The lottery ticket dispensing device employs a guiding press plate drive device, which includes a linear electromagnet, a lever, a pulling plate and a spring, to replace the solenoid or the mechanical clutch assembly of the prior art, so that the device cost may be lowered, the failure rate may be effectively reduced, and the service life of the machine may be increased. By adding a second drive roller and a ticket guiding device, it may be effectively prevented that failures such as ticket blocking and the like occur during ticket drawing.

(27) Although the invention has been described referring to exemplary embodiments, it may be understood by one skilled in the art that, various variations may be made to the forms and details of the invention without departing from the spirit and scope of the invention as defined by the claims.
