Description

The invention relates to a method for transferring extruded wire rings wound into protective pans into rings according to the preamble of claim 1 and to wire ring transports in the outlet of extrusion presses according to the preamble of claim 2, as are known, for example, from the following technical reports:
Dieter Veltjens, Zeitschrift für Metallkunde 62 (1971) 2, pages "Extrusion plants with auxiliary and subsequent devices for copper materials"; Dieter Veltjens, Metall 29 (1975) 11, pages 1110 to 1117, "Extrusion and Pipe Pressing Plants for the Heavy Metal Industry"; FJ Zilges, Metall 36 (1982) 4, pages 439 to 443, "Main criteria in the design of an extrusion plant for heavy metals".

Windable solid or hollow profiles, as summarized as "wires" are wound into coils in coils and on a conveyor track which is dimensioned for sufficient cooling of the wire rings is from the reels Follow-up devices for further treatment, for collecting, for setting the Rings and / or spent for removal, this transportation in protective pans he follows.

The wire rings that are coiled in the protective pans must be at the end of the Conveyor path from the protective pans to the subsequent facilities and the empty protective pans have to be transported back to the reel become. As a result of the handover process, the wire rings tend to become attached to theirs Spread out the protective pans and loosen their compact shape to lose. The object of the invention is an improved procedure Avoid loosening the wire rings when handing them over and compact them to keep.

a) ein in der Schutzpfanne liegender Drahtring zusammen mit der Schutzpfanne von der Hauptförderbahn übernommen und um 180° gewendet wird,

b) die Schutzpfanne angehoben und der Drahtring seitlich in Richtung der Folgeeinrichtung abgefördert wird; und

c) die Schutzpfanne wieder gewendet und seitlich an eine zu den Haspeln führende Rückförderbahn übergeben wird.

According to the invention, in the method for transferring extruded metal wires that are coiled into protective pans into rings from a conveyor track that transports the wire rings in the protective pans to a follow-up device in such a way that

a) a wire ring lying in the protective pan is taken over together with the protective pan from the main conveyor track and is turned through 180 °,

b) the protective pan is raised and the wire ring is removed laterally in the direction of the following device; and

c) the protective pan is turned again and laterally transferred to a return conveyor leading to the reels.

To exercise the method is in accordance with the preamble of the claim 2 designed wire ring transport the use of a Kippstuhls proposed as a transfer device, with the characteristic Features of claim 2 is formed. By using a The wire ring with the protective pan and in is the tilting chair as the transfer device this remains turned over and then the protective pan is lifted upwards, the wire ring remains on the surface against which the protective pan against the joint turning of wire ring and protective pan was raised.

D after the tilting chair has been turned back by 180 ° to the starting rotary position, but the pan support and conveying element is initially in the same area as the return path for transferring the empty protective pan before the pan support and conveying element is raised and returns to operating position A.

The extrusion press 1 shown in FIG. 1 is both stretched for pressing, rod-shaped metal profiles as well as metal profiles that can be wound, summarized under the term metal wires. The stretched Metal profiles are picked up and taken up by an outlet table or belt 2 a cross conveyor 3 cooled and removed from a saw roller table 4. The Metal wires are wound into coils 5 to form rings, which are conveyed by a conveyor track 6, on which the wire rings can cool during transport, follow-up devices, for example binding station 7 and a wire ring collector 8 fed. For handover of the wire rings from the conveyor track 6 to the in the embodiment as Binding station 7 provided with a conveying element 7a is a transfer device 9 between the conveyor track 6 and the conveyor element 7a of the binding station 7 arranged. When pressing stretched profiles they become the reels 5 leading channels from one that can be inserted into the press line Intermediate conveyor 10 bridges.

For certain materials of the wire rings, it is common to place the wire rings in protective pans to reel and to transport on conveyor 6. At the end of the conveyor track 6 the wire rings must be separated from the protective pans and the protective pans closed the reels are returned while the wire rings from the Transfer device 9 are transferred to the subsequent devices. details the transfer device 9 and its assignment to the conveyor track 6 and the Conveying element 7a of the binding station 7 can be seen in FIGS. 2 to 6. The Conveyor track 6 consists of a main conveyor track 11 for transporting the wire rings 13 with the protective pans 14 receiving them and one under the main conveyor track 11 arranged return conveyor track 12 for returning the empty protective pans 14 to the reels 5. Above the main conveyor track 11, fans 15 are required arranged to cool the wire rings 13 during the gradual feed.

The transfer device 9 is, as shown in particular in FIG. 4, as a tilting chair 16 one consisting of two rings 17 and webs 18 and 19 connecting them Frame trained. Rotary bearing 20, on which the rings 18 rest, support the its axis 21 rotatable tilting chair 16. The tilting chair 16 is rotated by one Geared motor 22, the axis of which carries a sprocket 23 which is connected to a chain 24 engages, which is guided over deflection piston 25 and the ends of which are connected to the rings 17 are connected.

The webs 18 are designed as bearing and gear boxes for rollers 26, the one Form ring conveyor element 27, of which the wire rings 13 (see operating position C, Figures 7 and 8) are transferred to the conveyor element 7a.

Between the webs 18 and 19 there are guide rods 28 for one of Piston-cylinder units 29 variable in distance from the ring conveyor element 27 guided table 30, provided with conveyor chains 31 a pan-carrying and Conveying element 32 forms the table 30 is with stops 33 and brackets 34 for Protective pans 14 provided.

The supply and control lines for the ring conveyor element 27 and that Pan support and conveyor element 32 are in one on one of the rings 17 and one Stand 35 attached energy chain 36 summarized.

The mode of operation of the transfer device 9 is shown in FIGS. 7 and 8 in FIGS Operating positions A to D described.

In the operating position A, the tilting chair 16 is in the running rotary position (Starting position). The pan support and conveying element 32 is located with its effective area 37 is level with the effective area 38 of the main conveyor track 11 and there is the downwardly facing active surface 39 of the ring conveyor element 27 µm at least, i.e. by a necessary game higher than the measure H = height of the Protection pans 14 over the active surface 38 of the main conveyor track 11, so that a Protective pan 14 with the wire ring 13 lying in it on the pan support and Conveyor element 32 can accumulate until that the protective pan 14 for contact with the Stops 33 (see Fig. 6) comes. The protective pan 14 is now by the Clamps 34 on the table 30 of the pan support and conveyor element 32 clamped and the pan support and conveyor element 32 is around the game for the Inlet of a protective pan 14 raised so that the protective pan to the system the ring conveyor element 27 comes.

The tilting chair 16 is then pivoted through 180 ° into the outward rotation position, such as this shows the operating position B. The ring conveyor element 27 is now with its active surface 39 at the same height as the active surface 40 of the conveying element 7a.

The pan support and conveyor element 32 - as in the operating position C shown - raised and with it the protective pan 14, so that the wire ring 13th is exposed and transported to the binding station 7 via the conveying element 7a can.

As soon as the wire ring 13 has released the ring conveyor element 27, the tilting chair becomes 16 rotated back through 180 ° into the operating position D, the pan carrying and Conveyor element 32 with its active surface 37 at the same height as the active surface 41 Return path 12 arrives. After loosening the clamps 34 is the protective pan 14 free for the return transport to the reels 5. The lifting of the Pan support and conveyor element 32 with its active surface 37 to the level of Effective area 38 (operating position A) of the main conveyor track 11, with which a following Protective pan 14 with wire ring 13 can enter the tilting chair 16.
