BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple feed device and bar material with a cartridge, coupled with a hydraulic separating device mainly for multi-spindle rotor machining.

The ends of the bar stock (with which the trays are filled) are pre-aligned to the exact spacing so that, when splitting, the full number of semi-finished products comes out, as previously known feed systems, operating with feed rollers or rollers, or feed grippers, cannot be secured. '

Said conditions are a multi-purpose bar material feed device according to the invention, wherein the entire bar material being fed is supported by a feed crossbar provided at both ends with spring-loaded latches which are provided with rectilinear ratchets adapted , or mounted in a sliding-mounted feed rod. ',. '‘

It is also an object of the invention that a multiple container of bar material is attached above the feed section and a guide plate provided in rows with alternating supports and sprung distributors is mounted below the feed crossbar, the bar feed materials being separated by the guide noses. o.Dispersed distributors and leaning against pulleys. Finally, the invention is based on the fact that the sprung distributor is pivotally mounted on the bolt in the grooves and the guide rail selected. Its guide noses are provided with lead-in sloping surfaces, while the distributor is spring-loaded and the feed cross member together with spring-loaded latches is secured to the link chain by pins and clips, \ t

The advancement and advantage of the multiple feed device and bar material of the present invention mainly lies in the fact that it allows the pre-aligned bar material to be delivered with such precision that the calculated number of blanks is fully maintained during administration in the entire bar material with absolute certainty. An exemplary embodiment of a multiple feed device and bar stock with a cartridge according to the invention is shown in the drawings, in which FIG. 1 shows a partial section through the stage A-A of FIG. 3, FIG. 2 a partial section along line B-B of FIG. FIG. 3 shows a partial section along line C-C of FIG. 1, FIG. 4 shows a plan view and FIG. 5 shows a section along line D-D of FIG.

The main parts of the device according to the invention are the feed bars T1, the straight ratchet 2, the feed crossbar 16, the spring-loaded pawls 3, the multi-magazine 5, the spring-loaded distributor 23. and the guide plate 11 fixed in the frame 13. 0 the entire 17-feed bar materials 14 is supported against the feed crossbar 16 provided with both ends of the spring-loaded pawls 3, 6 which engage with the straight ratchets 2 provided or mounted in the displaceable feeders. bars ·

A plurality of rod-shaped containers 5a are mounted above the feed rail 16 and a guide plate 11 is provided on the frame 13, provided with pulleys 12 and spring-loaded distributors 23 in the radius-wing 13, the rod-shaped materials 14 being separated by guide rails 21 of sprung distributors. 23 and supported on the pulleys 12, the pivot bearing of the bolt 1 5 s

The sprung distributor 23 is pivotally mounted on the bolt 24 in the grooves 10a in the recess 25, and its guide noses 21 are provided with sloping faces 22, further spring-loaded by the compression spring 26 and the feed cross member 16 together with the spring latches 3 ». 8. mounted on the link chain 9.,

The feed rods 2 slidably mounted in the guide holders 11 and at one end are further connected by a non-drawn connecting crossbar connected to the piston rod of the working cylinder. and

Claims (4)

211557 2 The sectional strip 2 allows the delivery crossbar 16 to be returned to the top of the next bar material feed 14, which abuts the rollers 12 of the multiple container 5 after completing the feed of the bar material 14. in the base position and the multiple container 5 filled with the bar material 14 aligned to an exact multiple of the blank, then the function of the multiple dispenser and bar material with the container according to the invention is in principle:. On the '' START CYCLE '' control pulse, the trailing bars T together with the straight ratchets 2 carry out a working stroke 13 forward and, through the spring latches 6 and the feeding crossbar 16, the rod-material 14 being fed is also displaced by one spacing 19 in the direction 18. forward into the separating device and the feed rod 7 actuated by the undrawn working roll, they move the auxiliary stroke to the basic position. This process is repeated synchronously with the working cycle of the machine, whereby the feeding crossbar 16 'fixed on the link chain 9 advances, with the aid of spring-loaded latches 3, 6, on the guide plate 11 in the forward direction together with the feed bar material 14. Red feed crossbar 16, the spring-loaded distributor 23 is pushed against the compression spring 26 into the recess 25 of the guidewheel 11 and releasably released over the passage of the feed rail 16. When the feed rail 16 is at the end of the guidewheel 11, then another of the the three guide rails 16 fixed at the same spacing on the link chain 9 are prepared in the starting position, while the guide rails 21 of the spring distributors 23 fit another rod-shaped matrix 2.4 from the multiple magazine 5 and the further working stroke of the feed rods 18 forward, another bar material is fed The length of the link chain as well as the spacing of the three feeder bars 16 are given by a bar-shaped bar material 14. Since the ends of the bar material 14 are precisely aligned with the exact multiple of the blank and its forward feed is derived from the straight ratchet 2, the saw teeth 20 are coincidentally spaced 19, such as the length of the blank or, in the case of splitting, this separation is added to the addition of the cut, the feed bar material 14 at the entire length is divided into the desired cuts precisely, reliably and completely.
