Title: Improvements in or relating to means for feeding sheets, particularly in printing machines
IPC: B65H1/30
Filed: 1952-06-27
Abstract: 723,157. Feeding sheets. FABER & SCHLEICHER AKT.-GES. June 27, 1952 [July 4, 1951; Aug. 13, 1951], No. 16245/52. Class 100 (1). Pile tables and supports.-In a sheet-feeding device of the type in which sheets are successively removed from the top of a pile on a pile support, the pile support comprises a top part and a separate bottom part which co-operate so that they may be elevated together with a pile of sheets resting on the upper part, the parts being separated and separable from each other, when the height of the pile is sufficiently reduced, so as to allow the lower part to be manually withdrawn in advance of the top part during the operation of the feeder. As shown in Fig. 1, the pile 1 rests upon the upper part 2 of the pile table, the part 2 being made of flexible sheet material and provided along its sides with U-shaped guide channels 3, 4 into which fits a strong lower part 5 of the pile table. The table 2, 5 is transported upwardly by carriers 7 provided on chains 8. The weight of the pile is initially so great that the top part 2 is bent and rests on the bottom part 5 of the table, but after a number of sheets have been removed the top part 2a is capable of maintaining the weight of the reduced pile 1a so that the strong bottom part 5a may be removed by sliding out between the guide channels 3, 4. At this point the part 2a is seized by holding pawls 12 so that the carriers 7 may be moved outwardly by suitable switch means to release the table 2a. Succeeding carriers 7, on continuous rotation of the chains 8 grasp the next pile of sheets. When these have been raised so as to contact the undersurface of the top part 2a and release it from the pawls 12, the part 2a is then withdrawn. During the removal of the parts 2a, 5a, a continuous feed is maintained. The top part may be constructed, as shown in Fig. 3, of slats 13, angle irons 13b being interposed between the carriers 7 and the pile table for supporting the parts 5 and 13. In an alternative embodiment (Figs. 5 and 6) the top part 2 normally rests on the bottom part 5 of the pile table, but is separated therefrom when it is capable of supporting the weight of the sheets unaided, by eccentrics 16 mounted on shafts 15 journalled in the carriers 7 and provided with quadrants 15a by means of which they are turned. In a fourth embodiment (Figs. 9 and 10) the slats 13 rest on bars 17 supported by the carriers 7 which also carry a slide 20 adjustable by screws 21. The slide 20 carries wedge portions 19 fitting in slanted recesses 18 of the bottom part 5 of the table. When it is required to separate the two parts of the pile table rotation of the screws 21 effects a lowering of the bottom part 5. A return movement of the chains 8, instead of a continued unidirectional movement, may be effected automatically by an electric control circuit, Fig. 16 (not shown), operation of which is initiated by contacts on the holding pawls 12 which are operated by the top part 2 of the pile table.
