Abstract

An improved lottery ticket dispenser includes a burster wheel having a cylindrical contact surface. The improved burster wheel provides for an increased range of operation so that greater misalignment between the perforation or line of weakness between adjacent tickets in a fanfold stream and the path of the burster wheel can be accommodated while still providing a reliable and effective separation of the adjacent tickets along the line of weakness.

Claims

1. A bursting mechanism for separating individual, planar articles joined together along a line of weakness comprising:

a transport mechanism for feeding said articles along a dispensing path to an outlet, wherein said transport mechanism includes at least one roller mounted for rotation about a roller axis of rotation;

a bursting station located along said dispensing path; and

a burster movably mounted for rotation about a burster axis of rotation to intersect said dispensing path proximate said line of weakness at said bursting station, said burster axis of rotation being generally perpendicular to said roller axis of rotation, said burster having a cylindrical contact surface which contacts said articles and separates a pair of adjacent articles along said line of weakness.

2. The bursting mechanism of claim 1 wherein the at least one roller of said transport mechanism further comprises:

at least one feed roller at said bursting station contacting said articles at a location along said dispensing path upstream of said line of weakness;

at least one discharge roller at said bursting station contacting said articles at a location along said dispensing path downstream of said line of weakness, said discharge and feed rollers each being rotationally driven and cooperating to hold said articles while said burster separates said pair of adjacent articles along said line of weakness.

3. The burster mechanism of claim 1 wherein said cylindrical contact surface on said burster extends completely around a circumference of said burster.

4. A lottery ticket dispenser comprising:

a transport mechanism for feeding a stream of lottery tickets along a dispensing path to an outlet, a pair of adjacent said tickets being separable from each other along a line of weakness therebetween, wherein said transport mechanism includes at least one roller mounted for rotation about a roller axis of rotation;

a bursting station located along said dispensing path; and

a burster wheel mounted for rotation about a burster axis of rotation to roll over said stream of tickets at said bursting station and thereby separate said pair of adjacent tickets, said burster axis of rotation being generally perpendicular to said roller axis of rotation, said burster wheel having a cylindrical contact surface on a perimeter thereof which contacts said stream of tickets and separates said pair of adjacent tickets along said line of weakness.

5. The dispenser of claim 4 wherein said cylindrical contact surface on said burster wheel extends completely around a circumference of said burster wheel.

6. The dispenser of claim 4 wherein the at least one roller of said transport mechanism further comprises:

at least one feed roller at said bursting station contacting said lottery tickets at a location along said dispensing path upstream of said line of weakness;

at least one discharge roller at said bursting station contacting said lottery tickets at a location along said dispensing path downstream of said line of weakness, said discharge and feed rollers each being rotationally driven and cooperating to hold said lottery tickets while said burster separates said pair of adjacent lottery tickets along said line of weakness.

7. A lottery ticket dispenser storing a plurality of lottery tickets connected in a fanfold stream, a pair of adjacent said tickets being separable from each other along a line of weakness therebetween, a transport mechanism having a roller mounted for rotation about a roller axis for feeding said stream of tickets along a dispensing path to an outlet, and a bursting station located along said dispensing path and a rotational burster movably mounted to intersect said dispensing path generally perpendicularly thereto and proximate said line of weakness at said bursting station, said lottery ticket dispenser comprising:

a cylindrical contact surface on said burster which contacts said stream of tickets and separates said pair of adjacent tickets along said line of weakness even if said cylindrical contact surface is offset from said line of weakness upon contact with said stream of tickets, wherein an axis of rotation of said burster is generally perpendicular to said roller axis.

8. The dispenser of claim 7 wherein said cylindrical contact surface on said burster extends completely around a circumference of said burster.

9. A method of separating individual generally planar articles joined together along a line of weakness comprising the steps of:

feeding a plurality of said articles connected together along a path, said feeding being accomplished with at least one feed roller rotating about a roller axis;

moving a burster to intersect the path; and

bursting said line of weakness with the burster contacting said articles proximate said line of weakness, said burster having a cylindrical contact surface which contacts said articles and thereby bursts said line of weakness and separates said pair of adjacent articles, said burster being rotated about a burster axis generally perpendicular to said roller axis during said bursting.

10. The method of claim 9 further comprising:

deflecting said articles with said burster in conjunction with said bursting step.

11. The method of claim 9 further comprising:

interrupting said feeding and holding said articles during said bursting with the at least one feed roller located upstream of said line of weakness and at least one discharge roller located downstream of said line of weakness.

12. The method of claim 9 further comprising:

spacing said burster from said line of weakness during said bursting.

13. A method of dispensing lottery tickets comprising the steps of:

feeding a plurality of lottery tickets connected together along a dispensing path, a pair of adjacent said tickets being separable from each other along a line of weakness therebetween, said feeding being accomplished with at least one feed roller rotating about a roller axis;

moving a burster generally perpendicular to the dispensing path;

bursting said line of weakness with the burster contacting said tickets proximate said line of weakness, said burster having a cylindrical contact surface which contacts said tickets and thereby bursts said line of weakness and separates said pair of adjacent tickets, said burster being rotated about a burster axis generally perpendicular to said roller axis during said bursting; and

discharging one of said tickets to an outlet.

14. The method of claim 13 further comprising:

deflecting said tickets with said burster prior to said bursting step.

15. The method of claim 13 further comprising:

interrupting said feeding and holding said tickets during said bursting with the at least one feed roller located upstream of said line of weakness and at least one discharge roller located downstream of said line of weakness.

16. The method of claim 13 further comprising:

spacing said burster from said line of weakness during said bursting.

17. A method of dispensing lottery tickets comprising the steps of:

feeding a plurality of lottery tickets connected together along a dispensing path, a pair of adjacent said tickets being separable from each other along a line of weakness therebetween;

intercepting said dispensing path with a burster and contacting said stream of tickets in a direction generally parallel to the line of weakness and spaced from the line of weakness;

bursting said line of weakness with said burster contacting said stream of tickets, said burster having a cylindrical contact surface on a perimeter thereof, said cylindrical contact surface contacts said stream of tickets and thereby bursts said line of weakness and separates said pair of adjacent tickets; and

discharging one of said tickets to an outlet.

18. The method of claim 17 further comprising:

interrupting said feeding and holding said stream of tickets during said bursting.

19. A method of dispensing lottery tickets comprising the steps of:

feeding a plurality of lottery tickets connected together along a dispensing path, a pair of adjacent said tickets being separable from each other along a line of weakness therebetween;

intercepting said dispensing path with a burster and contacting said stream of tickets;

bursting said line of weakness with said burster contacting said stream of tickets, said burster having a cylindrical contact surface on a perimeter thereof, said cylindrical contact surface contacts said stream of tickets and thereby bursts said line of weakness and separates said pair of adjacent tickets; and

interrupting said feeding and holding said stream of tickets during said bursting.

20. The method of claim 19 further comprising:
