U.S. Patent No. 3.95, granted August 27, 1976.
No. 3,312 proposes applying a mechanical shock to the upper edge of the electrodeposited metal plate to create fine voids, and injecting low-pressure fluid into the fine void to transform the upper edge of the electrodeposited metal into a cathode. Discloses a method for peeling an electrodeposited metal plate from a cathode by separating it from the cathode, and then inserting a rust to peel the electrodeposited metal plate from the cathode.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stripping method and apparatus for stripping electrodeposited metal notes from a cathode in a reliable manner using a rotating carousel within a relatively small working area. It is a purpose.

The present invention is directed to stripping an electrodeposited metal sort from a cathode, and the description will proceed in connection with stripping an electrodeposited copper sort or plate from a stainless steel cathode. However, this description is intended to be illustrative only, and the method and apparatus of the present invention can be used to peel and separate electrodeposited zinc sheets from aluminum cathodes, peel and separate nickel and cobalt sheets from cathodes, and to electrodeposit them on boat fishing. It will be appreciated that peeling and separation of metal sheets from permanent cathodes may also be utilized.

SUMMARY OF THE INVENTION The method of the present invention involves stripping an electrodeposited sort from a cathode by rotating it through 360° past a plurality of stations arranged around the circumference of a carousel. having a hanger bar vertically supporting the cathode around a carousel device mounted on the periphery of the carousel, and feeding the cathodes sequentially from a loading station onto the carousel; rotating the carousel to transport the cathode to a hammering station for loosening the upper edge of the sort from the cathode; peeling the cathode; rotating a carousel to transport the stripped sheets to a discharge station for discharging the stripped sheets;
rotating a carousel to transport the stripped cathode to a removal station for removal.

The upper edge of the electrodeposited sheet is loosened by clamping the upper edge of the cathode at a hammering station and striking the electrodeposited notes on the cathode in a random pattern near the upper edge of the note from both sides of the cathode.

At the opening station, the central portion of the cathode is laterally deflected in a first direction to create a gap between the upper edge of the electrodeposited sheet and the cathode and to reduce the gap between the upper edges of the electrodeposited sheet and the cathode.
tI gap, and laterally deflecting the cathode in the opposite direction to create a gap between the upper edge of the other electrodeposited sheet and the cathode, and retracting said finger from the cathode to remove the electrodeposited note. By peeling off from the cathode, a gap is formed between the upper edge of the electrodeposited sheet and the cathode. If the separation of the sheet from the cathode is not completed at this stage, it can be completed when another cathode or unfinished, and it is removed from the partially peeled notebook at another fully open station. is completed by feeding each of the sheets between a pair of stripping fingers which engage the upper edge of the sort and completely strip the sheet from the cathode upon retraction from the cathode. Ru. Furthermore, completion of the peeling may be accomplished for thin notebooks by providing a separation station after the opening or full opening station where the cathode is fixed and a pair of opposed peeling knives are lowered between the sheet and the cathode to complete the peeling from the cathode. Can be guaranteed by completion. However, it has been found that in most cases a full open station and an additional separation station are not required as a complete stripping operation is usually easily performed at the open station.

A passive guide extending to the next station can be interposed between the electrodeposited note and the cathode to prevent the sort from returning to rest against the cathode when the sheet is only partially peeled off. , and a second passive guide extending to the next station is located outside the electrocoated sheet to restrain the sheet from excessive lateral movement when it is completely freed from the cathode.
