Perforated ticket dispensing machine
The present invention provides an independently operable and serviceable ticket burster machine that properly handles perforated tickets of all shapes, sizes and thicknesses. The present invention includes a ticket burster element, an exit sensor with a mechanical flag switch, an inventory flag spanning the entire width of the ticket input slot and having an optical slot switch, a slidable ticket guide, one or more leaf spring arrangements and versatile and durable rollers.
1. A ticket burster machine for controlled delivery of perforated ticket products, comprising:
a frame having first and second side walls, with the side walls each having an inner and outer surface, the inner surfaces of the side walls together defining a frame interior, and with drive means secured within the frame interior for moving tickets therethrough, wherein the drive means comprises a feed drive roller, a feed idler roller, an exit drive roller and an exit idler roller;
a bursting element secured within the frame interior;
an input slot flag arrangement having an inventory flag that extends from the first side wall to the second side wall;
an exit flag pivotably secured to the first and second side walls;
a controller in communication with the inventory flag and exit slot flag;
at least one leaf spring arrangement mounted to the inside of the frame for applying pressure to the feed and exit idler rollers; and
a ticket guide arrangement including a ticket guide slidably secured to a guide retainer element that is secured to the frame, such that tickets of variable widths can be securely guided with adequate pressure on both sides as they are processed through the machine; and wherein the leaf spring arrangement includes a leaf spring guide member secured to the inner surface of the first side wall at a position nearer to the feed idler roller than the exit idler roller.
2. The machine of claim 1 wherein at least one of the rollers is formed from aluminum and has either an aluminum oxide or silicon carbide coating.
3. The machine of claim 1 wherein the exit flag is part of an exit flag arrangement that includes a Hall effect sensor secured to the outer surface of the first side wall, a magnetic conductor secured to the first side wall and a magnet secured to the exit flag.
4. The machine of claim 1 wherein the exit drive and idler rollers meet at an exit roller nip position, and wherein the exit slot flag extends inward of the frame towards the exit roller nip position.
5. The machine of claim 1 wherein the exit idler roller includes a core cylindrical element having a first diameter and at least one roller member element secured thereto and having a second diameter, and wherein the exit flag includes at least one baffle that can extend to a position that is radially between the core cylindrical element and the roller member element.
6. The machine of claim 1 wherein the inventory flag has an incoming ticket side edge and an exiting ticket side edge, and wherein the inventory flag is constructed with a center of gravity that biases the exiting ticket side edge upward.
7. The machine of claim 1 wherein the frame can be independently inserted into and retrieved out of a larger ticket dispensing machine.
