Description
Background of the Invention
This invention relates to ticket magazines, and more particularly to means for selectively feeding tickets from a magazine into a printer or the like.
Prior Art Statement
In the prior art, if the top ticket in a stack were to be fed to a ticket printer, the stack would have to be continually elevated. Apparatus to perform this function does not often operate well or at all.
Summary of the Invention
In accordance with the feed of the present invention, the disadvantages of the prior art are overcome by providing a magazine to hold a stack of tickets including means to allow only the bottom ticket in the stack to be withdrawn therefrom.
Brief Description of the Drawings
In the accompanying drawings which illustrate exemplary embodiments of the present invention:
FIG. 1 is a top plan view of one embodiment of the present invention;
FIG. 2 is a longitudinal sectional view of the embodiment shown in FIG. 1 taken on the line 2--2 shown therein; and
FIG. 3 is an enlarged longitudinal sectional view, partly in elevation, of a pair of roller-shaped bodies shown in FIG. 1.
Description of the Preferred Embodiment
In the drawings in FIG. 1, a ticket magazine 10 is shown having parallel sidewalls 19 and 20 fixed relative to each other. Rollers 11 and 12 are driven on shafts 13 and 14, respectively, by a motor 15, gears 16 and 17, and a toothed belt 18.
A stack of tickets 32 (FIGS. 2 and 3) lays on those portions of rollers 11 and 12 visible in FIG. 1. The ticket at the bottom of the stack (in contact with rollers 11 and 12) is then moved to the right as viewed in FIG. 2.
In FIG. 1, note will be taken that roller-shaped bodies 21 and 22 are mounted on shafts 23 and 24, respectively. Shafts 23 and 24 are fixed relative to sidewalls 19 and 20. Body 21 is fixed relative to shaft 23. Body 22 is rotatable on shaft 24. Body 22 is an idler roller.
Roller-shaped bodies 25 and 26 are mounted underneath bodies 21 and 22, respectively, on shafts 27 and 28, respectively. Body 25 is a driven roller via belt 29.
Body 26 is also a driven roller. Body 26 is driven by a motor 30.
Bodies 11, 12, 21, 22, 25 and 26 are all friction idler or driven rollers having a rubber periphery (with the exception of body 21). Body 21 has an anti-friction surface body 31 (FIG. 3) and is fixed to shaft 23 as stated previously. Body 31 begins within angle A, where A may be 30 degrees.
Rollers 22 and 26 are spaced a distance less than the thickness of one ticket--perhaps less than 0.010 inch. The bottom ticket is withdrawn to the right in FIG. 2 faster by rollers 22 and 26 than by rollers 11, 12 and 25. Thus, rollers 11, 12 and 25 all have conventional overrunning clutches. See typical overrunning clutch 33 in roller 25 in FIG. 3.
In FIG. 3, note that bodies 21 and 25 are spaced apart a distance D which is larger than one ticket thickness and smaller than two ticket thicknesses.
A conventional mechanical switch 34 is shown in FIG. 2 in a conventional ticket printer 36. Switch 34 is connected in series with motor 15 to disconnect the same when the right end of the bottom ticket, as shown in FIG. 2, is detected by switch 34. This prevents the next to last ticket in the stack from being driven to the right and from jamming the magazine when the same rests on roller 11.
Each of the bodies 11, 12, 21, 25, 22 and 26 of FIGS. 1, 2 and 3 is per se rubber and conventional. The same is true of motors 15 and 30.
Body 31 restrains movement of the ticket stack (except for bottom ticket 35) from moving to the right beyond the position shown in FIG. 3 where the same bear against body 31.
The ticket stack can move downwardly as viewed in FIG. 3 because body 31 is an anti-friction body.
Operation
In the operation of the ticket feed shown in FIGS. 1, 2 and 3, motor 15 rotates rollers 11, 12, and 25 via shaft 13 and belts 18 and 29. In this way bottom ticket 35 is pushed through the space D (FIG. 3) between bodies 21 and 25.
Driven roller 26 and idler roller 22 then press the right end of bottom ticket 35 therebetween and draw the same therebetween to a point past switch 34 to ticket printer 36. The ticket is then handled and printed in a conventional manner.
Switch 34 turns off motor 15 and allows rollers 11, 12 and 25 to free wheel until the left end of the bottom ticket 35 clears rollers 21 and 25.
All the while, body 31 restrains movement of the ticket stack (except for bottom ticket 35). All but bottom ticket 35 is thus prevented from moving to the right beyond the position shown in FIG. 3 where the same bear against body 31.
As stated previously, the ticket stack can move downwardly as viewed in FIG. 3 because body 31 is an anti-friction body.
As stated previously, the use of the present invention has advantages over the prior art. For example, if the top ticket of a stack is fed to a printer, the stack must be continually raised. The present invention thus is easier to operate in that the bottom ticket 35 is held positively and firmly against rollers 11 and 12 and the overrunning clutches allow the other driven rollers 25 and 26 to pull the bottom ticket positively forward.
Note will be taken that roller 21 is not necessarily a roller, but is preferably roller-shaped to accommodate tickets 32 and 35. The shape of roller 21 is not critical, but the surface against which the tickets bear is preferably cylindrical. A complete cylinder is not necessary for roller 21. Body 31 may be made of polytetrafluoroethylene (lubricous) or any other conventional material.
Roller 21 is equivalent to many other fixed members.
Motors 15 and 30 each may be a stepper motor and/or any other conventional unidirectional AC synchronous motor.
Many other equivalents are possible. For example, two rollers on one or more shafts is possible. A solid rubber shaft is also possible.
All of the rollers or bodies 11, 12, 21, 25, 22 and 26 may or may not have the same diameter. The tangential speeds of rollers 11, 12 and 25 are the same. The tangential speed of roller 26 is equal to or greater than that of, for example, roller 25.
