Title: Improvements in or relating to apparatus for unloading film sheet cassettes
Inventor: SANO KAREL MARCEL
IPC: G03D13/00
Filed: 1961-07-21
Abstract: 961,440. Feeding sheets. GEVAERT PHOTO-PRODECTEN N.V. Feb. 1, 1962 [July 21, 1961], No. 26584/61. Heading B6B. [Also in Division G2] In an apparatus for unloading exposed film sheets from casettes, the casettes are brought one by one to an unloading station where mechanism is provided for opening the casette, extracting the film sheet, and passing it on to a conveying arrangement; this latter comprises a first set of rollers which receive the film as it is being extracted from the casette, with further sets of rollers through which the film is successively conveyed, with controlling means for driving the rollers so that at least the first set rotate temporarily at a faster rate than a following set or sets during each unloading cycle. In the form shown, casettes 9, each containing an exposed film sheet, and resting on a support 10, are brought one by one opposite a slot 11 in a wall 12 and the casette opened, the mechanism being as described in Specification 961,439. The film sheet is extracted by the jaws 2, 3, which can be opened by a solenoid 4, and tilted about a pivot 5 to draw the sheet through slot 11, where it engages between a pair of rollers 13, 14. Then follow guide plates 15, 16, further rollers 17, 18, further guide plates 19, 20, and a final pair of rollers 21, 22, from which the sheets pass to a processing unit. The roller pairs can all be driven at the same speed by a motor. Roller pairs 13, 14 and 17, 18, however, are mounted on free travel couplings so that they can be driven by a second motor at an increased speed while rollers 21, 22 still maintain the normal speed. This increased speed is controlled by a microswitch 32, whose actuating member is depressed as a film sheet passes between guides 19, 20. When the member is not depressed, rollers 13, 14 and 17, 18 rotate at the increased speed. In operation, the jaws 2, 3 draw a film sheet out of casette 9, and carry it forward into engagement with rollers 13, 14. Assuming that the preceding sheet is not yet fully through guides 19, 20, and is still actuating the microswitch 32, all rollers are running at the lower speed. As soon as the rear edge of this sheet is clear of microswitch 32, rollers 17, 18 and 13, 14 run at the higher speed, conveying the new film sheet at this higher speed until its forward edge trips microswitch 32, when the rollers operate at the lower speed once more. Thus although the sheets are fed forward from rollers 21, 22 to the processing unit at a constant rate, the sheets being fed in from the successive casettes 9 are speeded up so that the distance between one sheet and the next is reduced. Microswitch 31, actuated as the rear edge of a film sheet passes from under it, initiates the movement of the next casette down into the unloading position. Specifications 889,384 and 961,438 also are referred to.
