Claim claimed - Begärd priority _ (73) Outokumpu Oy, Outokumpu, FI; Töölönkatu 4, 00100 Helsinki 10, Finland-Finland (FI) ~ (72) Leo Uusitalo, Tampere, Pertti Tuominen, Kaaro, Finland-Finland (Fl) (7 * 0 Berggren Oy Ab (5 * 0 Method and equipment for transport and for the handling of support bars packed in layers in a storage frame in electrolytic refineries - Förfarande och anordning för hantering av i en transport- och lagringshäck skiktvis packade bärstänger i elektrolytiska raffineringsanläggningar

The invention relates to a method for handling support rods packed in layers in a transport and storage frame in electrolytic refining plants. The invention also relates to a device for carrying out the method according to the invention.

In the electrolytic cleaning of copper, the support rods of the cathode plates are in the internal circuit of the refinery. Once the cathode plates have grown thick enough, they are removed from the pool. The support rods of the cathode plates are then removed and new Seed Plates are hung on the support rods.

With regard to the state of the art, reference is made to German Patent Publication No. I 188 299 and Finnish Patent Publication No. 46,266, which disclose a method and apparatus for mechanizing the manufacture of cathode plates. In the method according to German Patent Publication No. I 188 299, the support rods have to be handled. In the method according to Finnish Patent Publication No. 46,266, the seed plate production line and the cathode plate discharge line, on the other hand, must be located 2,5791 in parallel. In addition, the distance between these lines is quite precisely determined, as a result of which the equipment placement is inflexible and the space requirement is large.

In the Finnish pat.hak submitted at the same time as this application. No. 78I620 discloses a method and apparatus for treating support rods detached from cathode plates in electrolytic refining plants. In this method, the support rods detached from the cathode plates are transferred to a grouping position of support rods in a longitudinal transfer path, where the support rods are grouped into a predetermined group of support rods by moving the support rods transversely in the grouping station. This method achieves considerable advantages.

Firstly, a wide range of variations is provided for the mutual placement of the seed plate making machine, the cathode plate unloading machine and the electrolysis IIasham, so that optimal solutions for transport equipment, cranes and space can be achieved, especially in the modernization of old refineries. Secondly, in order to compensate for speed differences, the necessary storage of the support bars can be carried out with the aid of transport and storage frames at a considerably low cost and in a space-saving manner. In addition, the heavy work of the support rods, which requires manpower, is completely eliminated, so with the exception of the drivers of lifting and transport equipment, only monitoring personnel are needed.

It is an object of the invention to provide a method by which groups of support rods packed in layers in a transport and storage frame can be emptied in a simple and easy manner into a rod metering magazine by means of a seed plate manufacturing machine.

The objects of the invention are achieved by a method which is mainly characterized by (a) transferring the uppermost support rod group in the transport and storage frame one at a time longitudinally to the plateau above the seed plate machine; the support bar groups remaining in the transport and storage frame upwards so that the height of the support bar group in each case in the transport and storage frame is correct before the next longitudinal transfer of the support bar group to the platform above the seed disk machine.

It is also an object of the invention to provide an apparatus for carrying out the method according to the invention. The device according to the invention is mainly characterized in that the device comprises (a) a transfer device provided with a pusher for conveying the upper support group in the frame in the transport and storage direction in the longitudinal direction, (b) a plateau above the seed disk machine adapted to receive the pusher (c) a jet device for transferring the support bar assembly transferred to the platform of the device I to the bar dispensing magazine; and (d) a lifting device adapted to lift the support bar assembly in the transport and storage frame upward so that the transport and storage frame is at the top of the support frame. the next movement of the pusher.

The invention will be explained in detail with reference to a preferred embodiment of the invention shown in the figures of the accompanying drawings, to which, however, the invention is not intended to be exclusively limited.

Figure I shows a side view of an embodiment of a device for carrying out the method according to the invention.

Figure 2 shows a top view of the device according to Figure I.

In the embodiment according to Figures I and 2, the device according to the invention is generally indicated by the reference number I0. The device I0 comprises a transfer device I3 provided with a pushing device I4 for moving the support bars I2 packed in layers in the transport and storage frame II in the longitudinal direction.

The pusher I4 is provided with actuators I5 which provide a reciprocating movement for the pusher 14. The actuators 15 are preferably hydraulic or pneumatic working cylinders. The device 10 further comprises a plateau I7 above the seed plate machine 576, which is adapted to receive a group of support rods displaced by the pusher device I4. The device I0 further comprises a conveyor device I8 adapted to transfer the support dose of the support bar group transferred to the platform I7 to the bar magazine I9. Reference numeral 20 denotes a rod dispenser adapted to divide the support rods I2 individually for each seed plate to be manufactured. The device I0 further comprises a lifting device 2I, which is adapted to lift the support bar groups in the transport and storage frame II after the pushing device I4 has moved the respective support bar group in the transport and storage frame II to the platform I7. In this embodiment, the lifting device 2I is a lifting table moving up and down, the body part of which is denoted by reference numeral 1a 22.

The operation of the device I0 according to the invention is as follows. The complete transport and storage frame II, in which the support rods I2 detached from the cathode plates are packed, e.g. at the same time as the applicant's present application, in the filed Finnish pat.hak. No. 78I620 and by means of a device or other means, transported by means of a crane or forklift or other similar device to a seed disc making machine. The transport and storage frame II is placed on the lifting table 2I and locked to its frame 22. The pusher I4 of the transfer device I3, used by the working cylinders I5, transfers the seed of the uppermost support bar group in the transport and storage frame I1 to the platform I7. The conveyor device I8 conveys the support bar group transferred to the platform I7 to the bar dose Ium magazine I9, from which the bar lifter 20 distributes the support bars I2 one by one for each seed plate to be produced. The lifting table 2I controlled by the photocell or other similar control device lifts the support bar groups in the transport and storage frame II upwards and thus corrects the height of the uppermost support bar group now in the transport and storage frame II for the next movement of the transfer device I4. The above procedure is repeated until the transport and storage frame II is empty and replaced with a full transport and storage frame II.

The support bar group transferred from the transport and storage frame II to the platform I7 can also be moved forward in some other way. One possibility is that the support bar group is transferred from the plateau I7 to the bar dose magazine I9 by tilting the plateau I7 by means of cylinders (not shown) as disclosed in Finnish patent publication 46266.
