Definitions
- the invention relates to a device for removing storage foils from a protective cover.
- Image plates serve to record X-ray images of irradiated objects and patients. They contain storage centers, which can be converted by the X-rays into metastable electronic excitation states from which they relax upon exposure to readout light with emission of fluorescence.
- the imaging plates are made by a reader (scanner), in which the exposed imaging plates are inserted.
- Hygienic covers that surround the protective cover and ensure that the protective cover does not come into contact with bodily fluids or other contaminants.
- the envelopes surrounding the imaging plates had to be manually removed, which costs time and more
- the present invention is intended to provide a device for removing storage foils from a protective cover, which can remove protective covers from storage foils without manual labor.
- the protective cover is held on a region adjacent to an existing or to be created removal opening.
- the protective cover is pushed out, it can be taken over by a collection device of the read-out device (the scanner). This then pulls the memory film completely out of the protective cover, so that the latter comes free of the storage film and can be disposed of.
- Claim 5 indicates various alternatives with which the protective cover can be held. It is
- the cooperating form-fitting elements and form-fitting means can serve to position the protective cover.
- the storage disks are already bent to a curved geometry, as used in some read-out devices.
- the storage film can then be taken over from the removal device into the read-out device substantially while maintaining its geometry.
- the development of the invention according to claim 9 makes it possible to realize the pushing out of the storage film from the protective cover with the application of low force.
- the read-out device and / or the ejection of the empty protective cover can be started automatically when the front edge of the storage film has reached the feeder of the reader.
- the movement of the storage film is continued by the removal device at least until the front edge of the storage film has been taken over by the collection of the read-out device.
- a (the front) side of the protective cover is mechanically opened to provide a removal opening for the storage sheet.

- the storage film 14 is through the conveyor units
- the scan head 26 moves the laser beam 28 in the direction perpendicular to the plane of Figure 3 and the plane of movement of the storage film direction. In this way, the individual points of the storage film are read out separately.
- the output signal of the scan head 26 is applied to an operation and evaluation circuit 30 connected to the scan head
- the memory film 14 must be the latter surrounding protective cover 10 is removed, since it is impermeable to visible light, the laser beam used for reading
- the fluorescence light obtained in the excited storage centers is blue.
- Storage film 14 is in the reader according to FIG.
- a removal station 32 is provided. Various embodiments thereof are shown in FIGS.
- Figures 4 to 13 shown in more detail. They work on the same principle: the protective cover 14 is held in an area adjacent to the open end, and by applying a force to the rear edge of the
- FIGS. 4 to 13 differ in the means for holding the front, open end of the protective cover 10.
- like reference numerals refer to like-functionally identical components, even though they differ in detail.
- the squeegee 34 has a perpendicular to the plane extending distribution channel 38 which communicates with a plurality of suction channels 40 in communication, which opens into the conveying path of the protective covers 10 adjacent end face of the squeegee 34.
- the Andschreibor 36 has a plurality perpendicular to
- Pressure line 49 are connected.
- the protective cover 10 with the corresponding wall areas is securely held on the intake channels 42. Thereafter, the pressurization of the bores 48 may be terminated, and, if desired, by pressurizing the drilled holes 48, the piston 46 again be retracted.
- Figure 5 differs from that of Figure 4, characterized in that above the plunger 46 is still a sealing strip 50 is provided, which is made of flexible rubber material.
- the adhesive strip 52 is further provided with a pneumatic operated Slider 58 provided, which serves as a movable stop and facilitates a correct alignment of the protective covers 10 with respect to the housing 20 of the readout device 16.
- the slider 58 also serves to close the
- Inlet plate 22 if no storage film 14 of a protective cover 10 is to be removed.
- the slider 58 of the squeegee 34 is arranged opposite. In this way, he can at the same time take over the function of the pressing piston 46.
- a light-emitting diode 60 and a light-sensitive diode 62 are integrated, which together form a light barrier. This is interrupted when a storage film 14 is introduced with this surrounding protective cover 10 in the removal station 32.
- a predetermined period of time after interruption of the light barrier can then be released by applying vacuum to the back of the slider 58, the access to the inlet slot 22 automatically.
- the holding plates 64 are arranged so that they are in the
- the protective cover 10 is then clamped by the retaining plates 64 in each case against the end faces 44 of the respective retaining strip 66 and thus fixed.
- the protective cover 10 shown in FIG. 9 has a reinforcing strip 60 provided on one side in the lower edge region of the front wall 10A and provided with recesses 70.
