DE10121966A1 - Method and device for moving metal anode plates or metal anode rods hanging on contact bars in electrolyte tanks - Google Patents

Abstract

The method of displacement of anode plates (8) on suspension beams over electrolytic surface finishing or plating tanks (9). The method involves feeding fresh anode plates into the area of the strips to be plated to be positioned on either side of the strips. The anode plates on several suspension beams can be positioned simultaneously.

Description

The invention relates to a method and an apparatus for moving from Contact bar hanging metal anode plates or metal anode rods in Electrolyte tanks through an anode slide, especially for electrolytic Coil finishing or coating systems.

In such systems, metallic tape, e.g. B. steel strip, in an electrolytic process continuously coated, e.g. B. tinned. The metal Anode plates or the metal anode rods using a hook-like work stuff in the treatment area on both sides of the steel strip to be coated positioned. It is known to pack entire anodes by attacking a push rod to mechanically or hydraulically ver on the last attached outer anode slide. The push rod is connected to a push device that is is located approximately at the level of the anode heads and is transportable (DE-OS 23 23 788). The actuation of the pusher, d. H. the driving back and forth takes place still by an operator. The anodes are hooked in still by hand. It is possible through the thruster, the anodes with the system running at full speed in a short time and without accident or move the belt. However, it is still like before difficult, the anode package sufficiently accurate to the metal strip to be coated  align and follow up during coating and z. B. the To change the coating thickness in the band edge area.

The invention has for its object, regardless of the replenishment individual new anode plates or anode rods, whole anode packages faster 4 and position it more precisely.

The object is achieved in that the on the An new anodes automatically placed in the area of the layered tape pushed and centered or staggered on both sides positioned in a controlled manner on the belt. This allows the entire anode pair ket by the number of new, unused anodes compared to the be layering tape shifted and ge in the most favorable coating position will drive. The entire anode package thus becomes the one to be coated Band aligned favorably. The position of the anode stack is no longer the same Handling dependent on the operator.

According to further advantageous steps, it is provided that with the Retraction of the anode slide on the opposite side one or more, ver needed anodes pulled out of the coating area and into the Change position are driven.

The performance of the system can also be increased by using more metal anode plates located at the same time the.

With the device for moving Me hanging on contact bars tall anode plates in electrolyte tanks by means of an anode slide, in particular in electrolytic strip finishing or coating systems, the posed  Object achieved according to the invention in that a beam crossbar is supported on both sides of the bridge bearing and that vertically and / or under egg nem acute angle to the tape running direction by means of a drive several on the Move the metal anode contact bar into the coating position are cash. This allows a controlled positioning of the anodes over the Bandwidth take place and the whole anode package can be adjusted. The entire set of anodes can be increased by the number of new, unused ones Anodes shifted relative to the strip to be coated and in the cheap position.

According to further features, it is provided that the beam crossbar is positioned next to one another the treatment tank arranged slidably supported bridge bearings and has rotatably mounted adjusting spindle, with the adjusting at one end spindle attacks a drive motor. When rotating by the drive motor, the The Balkentra can be operated electrically, hydraulically or pneumatically verses pushed back and forth.

According to a further embodiment it is provided that the adjusting spindle and the pivot bearings and threaded nuts are surrounded by a base frame that even from a front travel frame and a rear travel frame Part lengths is surrounded. The adjusting spindle therefore remains in any position surrounded by the base frame and thus protected.

Another improvement is that one is attached to the beam crossbar arranged hook in the rearmost, used metal Anode can be snapped into place.

An increase in performance of the system is achieved in that the beam crossbar interacts with several contact bars running parallel to each other.  Moving the beam crossbar affects everyone on the contact metal anodes.

The adjustment of the beam crossbar can be technically and economically favorable be carried out by using a single drive for the multiple contact bars Beam crossbar is provided.

For safe operation and fault-free operation, it is also advantageous that the buffers on the beam crossbar are electrically insulated and / or electrically isolated driver pawls are provided.

The security of the functions can be further increased by the ge entire beam crossbar is hung or stored in an electrically insulated manner.

In the drawing, exemplary embodiments are shown, based on which the procedure ren and the device are explained below.

Show it:

Fig. 1 is a plan view of the beams traverse with bridge bearings,

Fig. 2 is a vertical longitudinal section BB of Fig. 1,

Fig. 2A is a detail C of Fig. 2 and

Fig. 3 is a vertical cross-section AA in FIG. 2.

Referring to FIG. 1, a beam cross member 1 is formed at the ends angeord Neten bridge bearings is propped 2 and 3. The crossbar 1 runs perpendicularly and / or at an acute angle to the strip running direction 4 (cf. FIG. 3) of the metal strip, in particular steel strip 5 . The metal strip 5 is guided around a current roller 6 , so that the metal strip 5 between two anode rows (soluble metal anode plates or metal anode rods) is continuously transported before.

The anodes 7 are located on a contact bar 8 and hang from the latter into an electrolyte tank 9 which is filled with electrolyte liquid up to the liquid level 10 . The metal anodes 7 hang in the coating position 11 , ie at a distance from the metal strip 5 , which is electrolytically favorable.

The beam crossbar 1 has sliding bearings 12 and 13 with pivot bearings 14 and 17 which can be pushed back and forth together with threaded nuts 15 and 16 by means of an adjusting spindle 18 .

The beam crossbar 1 forms at the ends of a front and a rear ren moving frame 19 and 20th In Fig. 1, the left moving frame 19 is drawn in the rest position and the right moving frame 20 in the alternating position with a displacement path 21 , which is dependent on the width ratio of the metal strip 5 , so that different widths can be treated.

The displacement path 21 is carried out by means of a drive 22 which is mounted on the adjusting spindle 18 and z. B. may consist of an electric rotary motor 22 a.

The adjusting spindle 18 and the pivot bearings 14 and 17 and the threaded nuts 15 and 16 are surrounded by a base frame 23 which is surrounded by the front travel frame 19 and the rear travel frame 20 on the part lengths shown 24 . On the front travel frame 19 , the anode slide 1 a is attached.

On the crossbar 1 ( Fig. 2A) a hook 25 is also attached, which has a slave pawl 26 . The pawl 26 is in the last one, or more, consumed metal anodes 7 are latched and these can then be withdrawn.

The beam crossbar 1 can operate a plurality of parallel contact bars 8 (as shown in FIG. 3). For several contact beams 8 , the drive 22 is provided as the only drive which adjusts the beam crossbar 1 as a whole.

On the crossbar 1 are far electrically isolated sliding buffers 27 and / or electrically isolated suspended pawls 26 hen hen. The entire beam crossbar 1 can be hung electrically insulated or gela gert.
