1,087,954. Machine tool details. ZAVODY P#RESN#EHO STROJ#IRENSTV#I GOTTWALDOV N#ARODNI PODNIK. May 7, 1965 [June 13, 1964], No. 19412/65. Heading B3B. In a feeding apparatus for round parts and used in connection with automatically operated machine tools of which the feeding device takes the semi-products P from a shoot and replaces machined products O on the shoot, first and second stop members are provided on the shoot there being provided a space between the said stop members which serves for both the removal of the semiproducts P and the replacing of the machined parts O. The shoot has an angle girder 2 with a vertical wall, a supporting bar 7 and a guide bar 8, the bars 7, 8 being adjustable as to their vertical position on angle pieces 9 which are horizontally adjustable so that the bar 8 forms a second vertical wall. The first stop member 28 is adjustably secured to the spacing rod 22 of a pair of tilting arms 21 accommodated one on each side of the shoot, the stop being fixed in one sense while in the other sense it is tiltable against the action of a helical spring 35 located on the spacing rod 22. A workpiece O being deposited on the shoot, strikes the extension arm 33 of the stop 28 causing the stop to turn and a semi product P to be released. The semi-product P rolls towards the middle section of the shoot into which in the meantime the machined workpiece O has. been deposited. The second stop member 37, Fig. 4, comprises a tiltable barrier which passes through the girder 2 and is connected to a hinge-pin 38 through a laterally tiltable side arm 371 coupled to the hinge pin 38, the latter being fixed to the arms 39 of an angularly adjustable shaft 40 connected to a hand-operated setting lever 41. The tiltable arm 37<SP>1</SP> is controlled in one sense by the depositing grip of the feeding apparatus and in the other sense by a helical spring whereby the barrier 37 is always pushed upwards. A spring-loaded cross-bar 49 is arranged in an aperture of the girder 2. The lower part of the cross-bar being pushed into mechanical contact with a microswitch (51) in the electrical control circuit of the feeding device of the machine tool by the part O deposited on the shoot. After the machined workpiece O has been returned to the shoot the gripping means moves away and strikes a lateral arm 58 which pulls the barrier 37 to a position allowing the machined workpiece O to roll to the lower part of the shoot.
