Title: Improvements in, or relating to, sheet conveyors for printing or other machines
IPC: B65H29/60
Filed: 1928-04-25
Abstract: 317,870. Watson, A., and Ballard & Co., Ltd., F. J. April 25, 1928. Printing-apparatus combined with drying- apparatus.-Sheets or plates, e.g., of sheet metal, being delivered from a printing, varnishing, or other machine are directed into a number of streams by means of an endless conveyer arrangement and passed into a corresponding number of drying units, or, using the conveyer arrangement reversed, the sheets may be delivered in a single stream from a number of machines and passed through a single drying unit. In one form, Figs. 1 and 2, the sheets are directed from a fixed delivery conveyer 2 alternately on to diverging conveyers A, B which carry them to conveyers 41, 42 passing them through drying units. The pulleys carrying the front ends of the conveyers A, B, are mounted in a frame 8 pivoted to a weighted lever 11 oscillated from a cam 21 so as to bring each conveyer alternately level with the conveyer 2. The other ends of the conveyers are mounted on fixed axes 30, 31, the shafts being coupled by a universal joint 45. An idler roller 43 prevents the lower run of the upper conveyer A from fouling the conveyer B. In a modified arrangement, the conveyers A, B are stationary and the conveyer 2 is arranged to be oscillated about a fixed axis similarly to the lever 11, so as to direct alternate sheets to the conveyers A, B, respectively. In further modifications, the frame 8 or the frame carrying the adjacent roller of the conveyer 2 is reciprocated in vertical guides to direct the sheets as described above. In another form, Fig. 7, sheets coming from a conveyer 115 on the alternately on each half of a double width conveyer 88, mounted on a carriage 83 reciprocated transversely on guides 90 so that each half of the painting and varnishing machine are received conveyer is alternately in line with the conveyer 115 and with one of the conveyers A<2>, B<2> respectively, thus forwarding the sheets alternately to the conveyers 114 of the drying units. Threaded guides on the carriage 83 engage a rotating screwed spindle 96 having a sleeve 98 splined thereto, which has two discs 97 thereon. The sleeve 98 is reciprocated on the spindle 96 by cam mechanism so as to bring the discs 97 alternately into contact with a driving disc 99 so as to rotate the spindle 96 alternately in opposite directions and thus reciprocate the carriage 83.
