Abstract

Abstract A device for the speedy removal of exposed light sensitive material such as films, foils, or papers from an appropriate holder in the exposure plane of a process camera, the holder being incorporated in the camera back in such a way that it may be moved out of the exposure plane to a position where the exposed film can be engaged by automatic gripper means and delivered for the automatic transport to a subsequent processing station.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 146 words
A means for fast removal of exposed light-sensitive sheet material from the holder plate of a process camera and for transport of such material to a subsequent processing station, characterized by the holder plate 10 for said sheet material 11 being mounted in the camera back 1 for backward and forward swinging movement relative to the exposure plane and about a fixed axis, drive means 7- 8-9 for swinging said holder plate, movable grippers 24, 25; 41, 42 having a back and forth operational range including a rearward edge of the holder plate when it is in a backward position, means 23, 38 for operating the grippers to grasp the sheet material on the holder plate when the plate is at its backward position, and means 20, 37 for moving said grippers rearwardly after sheet grasping operation thereof to remove said sheet from the holder plate.
Claim 2
Dependent Claim 146 words
A means for fast removal of exposed light-sensitive sheet material from the holder plate of a process camera and for transport of such material to a subsequent processing station, characterized by the holder plate 10 for said sheet material 11 being mounted in the camera back 1 for backward and forward swinging movement relative to the exposure plane and about a fixed axis, drive means 7- 8-9 for swinging said holder plate, movable grippers 24, 25; 41, 42 having a back and forth operational range including a rearward edge of the holder plate when it is in a backward position, means 23, 38 for operating the grippers to grasp the sheet material on the holder plate when the plate is at its backward position, and means 20, 37 for moving said grippers rearwardly after sheet grasping operation thereof to remove said sheet from the holder plate.
Claim 3
Dependent Claim 54 words
A means according to claim 1 wherein the holder plate 10 comprises a suction board, and wherein means is provided for pulling a vacuum on the suction board, means is provided for releasing the vacuum, and means is provided for operating the last named means when the plate holder is at said backward position.
Claim 4
Dependent Claim 26 words
A means according to claim 2 wherein the means for releasing the vacuum is operated by the plate holder when it reaches the said backward position.
Claim 5
Dependent Claim 51 words
A means according to claim 1 or 2 wherein a sheet transport mechanism is disposed within the range of rearward movement of the grippers for receiving the sheet material therefrom, and means are provided for operating the grippers to release said sheet material as it is received by the transport mechanism.
Claim 6
Dependent Claim 45 words
A means according to either of claims 1 or 4 wherein the means for moving the grippers rearwardly comprises a pivotally mounted arm on which the grippers are carried and which is swingable about an axis extending parallel with the plane of the camera back.
Claim 7
Dependent Claim 50 words
A means according to any of claims 1, 4 or 5 wherein the grippers are carried by swingable arms mounted on a rotatable shaft extending between brackets projecting from the camera back, and motor means is provided for swinging said arms rearwardly from the rearward position of the plate holder.
Claim 8
Dependent Claim 58 words
A means as defined by claim 4 wherein the sheet transport mechanism includes parallel pairs of upper and lower belts arranged to receive the sheet material between them, and a grate means comprising parallel upper and lower rows of rollers is disposed to receive the sheet material from the said belts for further transport toward subsequent processing means.
Claim 9
Dependent Claim 83 words
A means as defined by claim 4 wherein the sheet transport mechanism comprises a plurality of parallel pairs of upper and lower belts arranged to receive the sheet material between them, the upper belts being one part and the lower belts being another part of the transport mechanism, and wherein one of said parts is movable away from the other when the sheet is entered between them by the grippers and movable toward the other when the sheet is released from the grippers.
Claim 10
Dependent Claim 89 words
A means according to claim 2 wherein a sheet transport mechanism is disposed within the range of the rearward movement of said grippers for receiving the sheet material therefrom, means are provided for operating the grippers to release the sheet material as it is received by the transport mechanism, and control means are provided for sequentially swinging the holder plate backwards, operating the grippers to grasp the sheet material, releasing the vacuum, moving the grippers rearwardly, and then releasing the grippers from the sheet material, in the order stated.
