Abstract

814,697. Grinding. SCHUMAG SCHUMACHER METALLWERKE G.m.b.H. May 29, 1957 [May 30, 1956], No. 17102/57. Class 60. [Also in Group XXX] A device for feeding round bars or tubes axially and one at a time into a grinding or polishing machine, particularly a centreless grinder, has means for receiving a bundle of bars 6 and periodically dropping the lowermost bar for engagement by feed means comprising oppositely-facing feed discs 20, 21 which are relatively staggered so that only their edges overlap and rotated in the same direction so that a bar is fed forwardly while it is supported by a rail 22 disposed below the centres of the discs. The bars are placed as a bundle with one end against a stop 29 in a trough 28 and the other end on a lever 1 which is pivoted on a fulcrum 2 and has a forked and slotted end disposed above a slotted shoot S formed between two stationary members 3, 4, one of which can be adjusted by a screw 12 for different diameters of bars. As the lever is oscillated by the periodic energisations of a solenoid 14 acting against a return spring 15, a projection 18 on the lever and a vertically-adjustable projection 7, which is movable about a pivot 9 against the action of a spring 11 by a pin 9a secured to the lever, move to permit the lowermost bar in the trough 28 to drop onto the rail 22 and between the discs 20, 21. The weight of this bar holds a contact 17 open until the bar is fed sufficiently far into the machine to let the contact close and operate an electrical time switch 23 which allows for the bar to pass between the feed discs before the solenoid 14 again is operated to move the lever and release the next bar. The height of the rail 22 and the distance between the discs 20, 21 can be adjusted to control the rate of feed and rotation of the bar. In the arrangement shown in Fig. 2, the bars are fed from the discs 20, 21 between a pair of grinding wheels 24, 25 and between discs 26, 27 which are similar to the discs 20, 21 but which also act to polish the bar after the latter has been ground.
