- 2. Background of the Prior Art
- The use of photo-stimuable phosphor imaging plates in a dental operatory are replacing the usage of x-ray films since photo-stimuable phosphor imaging plates are reusable over an extended period of time. Photo-stimuable phosphor imaging plates are similarly exposed to a source of x-ray radiation, however are thereafter optically scanned with the resulting information stored in a suitable computer processing unit. In U.S. patent application Ser. No. 10/919,123, filed Aug. 16, 2004, assigned to the same assignee as the present invention there is disclosed a process and apparatus for optically scanning exposed photostimuable phosphor imaging plates. In U.S. Pat. No. 6,866,149, assigned to the same Assignee as the present invention, there is disclosed a barrier envelope used for protecting the restored image plate.
- Since such exposed photostimuable phosphor imaging plates are reusable, the thus scanned imaging plate is subjected to luminescence to discharge electrons forming the latent image to restore imaging capability. In U.S. Pat. No. 6,778,776, issued Aug. 17, 2004, and assigned to the same assignee as the present invention, there is disclosed an apparatus for restoring imaging capabilities of exposed photostimuable phosphor imaging plates. Such restored imaging plates must be enclosed in a barrier envelope prior to reuse.
- An object of the present invention is to provide a process and apparatus for positioning and sealing restored photo-stimuable phosphor imaging plates in a barrier envelope in a facile manner.
- Still another object of the present invention is to provide a process and apparatus for positioning and sealing restored photostimuable phosphor imaging plates to ensure effective enclosure within a barrier envelope.
- Yet another object of the present invention is to provide a process and apparatus for positioning and sealing restored photostimuable phosphor imaging plates within barrier envelopes requiring minimal manipulation of restored photostimuable phosphor imaging plates.
- A still further object of the present invention is to provide a barrier envelope blank for restored photostimuable phosphor imaging plate of facile handling.
- Still another object of the present invention is to provide a barrier envelope blank for restored photostimuable phosphor imaging plate provide aseptic properties to a resulting barrier envelope enclosing an imaging plate.
- These and other objects of the present invention are achieved by a process and apparatus for positioning and sealing photostimuable phosphor imaging plates within barriers envelopes blanks formed on a roll thereof wherein a barrier envelope blank including a U-shaped heat sealed portion thereof of such a roll is indexed to a positioning station whereat the barrier envelope blank is caused to be opened at a free end thereof thereby permitting insertion of a restored imaging plate into such barrier envelope blank whereupon the barrier envelope blank including restored imaging plate is indexed to station whereat heat sealing of the free end of the U-shaped heat sealed is effected to thereby encloses the restored imaging plate therein and thereafter the thus heat sealed barrier envelope is indexed to a product station for removal from the roll of barrier envelope blanks.

Thefixed platen member 94 functions as an anvil for the heat sealing process. Theheating platen member 96 is provided with an inverted U-shaped member (not shown) to complete sealing of a thus inserted imaging plate in the barrier envelope blank BE to complete the process of protecting the thus enclosed imaging plate within a barrier envelope. - Associated with the advancement
drive roller members 80 is a sensor assembly, generally indicated as 100, which senses the registration indiciaportions 56 to insure proper registration of barrier envelope blanks being processed and alignment within the heat sealing station. - In operation, referring to
FIGS. 4 and 5 , a barrier envelope blank BE is indexed to thepositioning exit 22 of thetop member 14 whereinchamber 50 thereof is accessible for manual insertion of a restored imaging plate. After insertion, theactivation button 24 is contacted to cause theplaten member 96 to be raised to processing temperature and themotor 68 activated to rotate theshaft 70 and consequently theshaft 76 via thegears platen member 96 into contact with theplaten member 94 effect contact between the heat sealing elements for a time sufficient to completely heat seal the thus positioned imaging plate within the barrier envelope blank to for a barrier envelope of such imaging plate. Thereafter, themotor 68 is caused to rotate in an opposite direction returning theplaten member 96 to its rest position while simultaneously rotating theshaft 80 including theadvancement drive rollers 82 to cause theroll 30 of barrier envelope blanks to be advanced by a length dimension determined by the distance between separation lines thereby passing the barrier envelope including encapsulated imaging plate to theproduct removal station 28. - It will be understood by one skilled in the art, that the process and apparatus of the present invention is capable of processing barrier envelope blanks of varying dimension to accommodate imaging plates of various sizes used in the dental operatory. Accordingly, the process and apparatus of the present invention is accordingly adjusted prior to processing barrier envelope blanks of such varying dimension.
- While the present invention has been described in connection with an exemplary embodiment thereof, it will be understood that may modifications thereof will be apparent to those of ordinary skill in the art and that this application is intended to cover any adaptations or variations thereof, and therefore it is manifestly intended that this invention be only limited by the claims and the equivalents thereof
