Abstract
1475469 Storage means based on winding and unwinding GOSUDARSTVEN NI I PROEKT INST SPLAV I OBRABOT TSVETNY METALLOV GIPROTSVETMETOBRABOTKA 9 Sept 1975 37136/75 Headings D1J and D1T A storage device for material to be processed comprises two freely rotatable drums 13 and 15, Figs. 6 and 7, of different diameters, the smaller-diameter drum 13 being eccentric with respect to the larger-diameter drum 15 by an amount equal to the difference in radius between the two drums, the axis of the drum 13 being rotatable about the axis of the drum 15 in both directions; and a device 25, Fig. 4, for guiding material during its transfer from the drum 15 to the drum 13. The device 25 rotates about the axis of the drum 15. Fig. 1 shows the storage device in a draw bench for billets. A billet 2 from a coil 1 passes through a butt welding machine 3, is wound several times around the larger drum 15 of the storage device 4, and is then passed through the device 25 of Fig. 4 before being wound around the smaller drum 13 of the storage device 4. Thereafter the billet passes through tension control means 5, a billetpusher 6, a die 8 and a draw block 9 from which coils of the billet are deposited in a container 11. When the coil 1 is empty a brake 26, Fig. 3, is applied to the larger drum 15 to stop its rotation. A member 17 carrying the axis 18 of the smaller drum 13 is then caused, by drive means 22, 23, to rotate in a direction opposite to that in which the larger drum 15 was running. Owing to the difference in diameters of the drums 13 and 15 each revolution of the member 17 results in turns on the drum 15 being transferred to the drum 13 so that the drawing process through the die 8 can continue. In the mean time a billet end from a further coil 1, adjacent to the coil 1 shown in Fig. 1, is guided to the welding machine 3 and is butt-welded to the now stationary end of the previous billet length. When the butt weld has been completed the brake 26 acting on drum 15 is released and the direction of rotation of the member 17 is reversed by reversing the direction of rotation of the motor 22. This causes the extra turns accumulated on the smaller drum 13 to be used up by the drawing process and for turns to be accumulated on the larger drum 15 to make up for the turns unreeled from that drum during the butt-welding operation. As soon as all the turns collected on the smaller drum 13 during the abutting operation have been removed, the member 17 is braked and the drums 13, 15 continue to run freely about their spindles and the turns on each drum then remain constant.
