Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for changing the conveyance direction of an electrode plate in electrolytic refining of non-ferrous metals, and is particularly suitable for use with an electrode plate having a crossbar protruding from both sides. It is something.

Electrolytic refining of non-ferrous metals is carried out by electrodepositing the metal to be refined dissolved as ions in an electrolytic solution onto a cathode plate. Therefore, it is necessary to select the material of the cathode plate that is most suitable for the electrolytic work.

For example, lead is used as the cathode plate in lead electrolytic refining, copper-based cathode plate is used in copper electrolytic refining, and aluminum is used as the cathode plate for zinc. In general, the electrode plates that serve as anodes and cathodes during electrolytic refining of nonferrous metals include:
A conductive crossbar (beam) that serves as a support member for suspending or transporting these into the electrolytic cell protrudes from both sides of the upper end, and the presence of this crossbar is due to the presence of the electrode plate. It has become a characteristic feature of the shape.

When transporting such electrode plates, it is often convenient from various points of view to change the transport direction of the electrode plates as appropriate in order to make effective use of the grounds of the electrolytic refining factory.

However, conventional conveyors transport electrode plates suspended from a single chain using a number of hanging metal fittings fixed at regular intervals, but while the conveyance direction of the electrode plates can be easily changed even in relatively narrow spaces, the structure of the conveyor First, it is not suitable for transporting heavy objects such as lead cathode plates, each weighing 300 kilograms, and
A conveyor in which the electrode plate is placed on two chains so that the crossbar of the electrode plate straddles two parallel chains is suitable for conveying heavy objects, but it is not suitable for carrying electrodes in narrow spaces. It was difficult to change the conveying direction of the plate. Therefore, in order to make effective use of the site of such a non-ferrous metal electrolytic refining factory, the present invention is capable of reliably changing the transport direction of heavy electrode plates such as lead cathode plates even in narrow spaces. The purpose of the present invention is to provide a conveying device, and its configuration is such that a plurality of cranks are connected to a link having hooks at the upper end that support cross-spars protruding from both sides of an electrode plate, and the hooks draw a circular trajectory. A first transfer machine, which has a parallel crank mechanism so as to rotate and has an incoming end and an outgoing end facing each other in the direction of transport of the electrode plate set on the circular orbit, is moved while supporting the crossbar of the electrode plate. A second transfer machine having the same configuration as the first transfer machine is installed so that the output end of the first transfer machine that transports The carrying-in end of a second carrying machine, which is installed in a direction different from that of the carrying machine and which carries the electrode plate from the first carrying machine while supporting its cross spar, is connected to the carrying-out end of the second transfer machine. A support member is provided to support the cross spar of the electrode plate, and when the horizontal beam that rotates between the first transfer machine and the second transfer machine is located at its turning end, is located at the unloading end of the first transfer machine and also at the rotating unloading end! One end of the horizontal beam is attached to a vertical pivot axis, and the other end is guided with a constant curvature around this pivot axis, so that the support member is located at the input end of the second transfer machine when the horizontal beam is moved. A support member is attached to the rail,
The hook of the first transfer machine scoops up the electrode plate that has reached the discharge end of the first conveyor and transfers it to the support member of the horizontal beam located at the discharge end, and then the horizontal beam turns. the direction of the electrode plate is changed, and the electrode plate that has reached the turning discharge end is scooped up by the hook of the second transfer machine and transferred to the second fourth transfer machine. It is something to do. Hereinafter, as shown in FIG. 1, which is a plan view of a part of a lead electrolytic refining factory, a device for changing the conveying direction of an electrode plate according to the present invention is used. As shown in FIG. Chain conveyor 3 taken out from tank 2

The supporting chain conveyor 3 transports the cathode plate 8 to the right in the figure by the operation of the conveyor drive motor 10. A first conveyor 12 is connected to the chain conveyor 3 for scooping up the cathode plate 8 suspended from the chain conveyor 3 from the discharge end and conveying the same to a first transfer machine 11 installed in front of the chain conveyor 3. This first conveyor 12 has a support arm 14 which has an engagement support member 13 at its lower end that engages with the crossbar 9 of the cathode plate 8, and whose upper end is pin-coupled with a horizontal portion 15 at the upper end of this support arm 14.

In this embodiment, a horizontal part 15 is formed on the support arm 14, and two swing links 17 are connected to this horizontal part 15 with pins, and the parallel link mechanism ensures that the engagement support member 13 is fixed at its input end and output end. However, since the weight of the cathode plate 8 allows the support arm 14 to always be in a vertical state, the horizontal part 15 of the support arm 14 is omitted and the support arm 14 is not allowed to swing. Only one movable link 17 may be pinned, and this swing link 17 may be connected to the first conveyor driving fluid pressure cylinder 19.

In this case, the cathode plate 8 swings back and forth at the unloading end of the first conveyor 12 due to the inertial force accompanying the movement of the cathode plate 8, and the cathode plate 8 is transferred to the first transfer machine 11. may be uncertain. The first transfer machine 11 connected to this first transfer machine 12 has two cranks 2 arranged above and below a pedestal 16.
