Abstract
Abstract An automatic transferring and processing apparatus of a cathode and method thereof. A cathode having an electro-deposited metal is taken out of an electrolytic cell, rotated by a stock cathode pivot, transferred through a stock moving carriage and stock conveyor to a processor for processing an electro-deposited metal disposed on the cathode, transferred through an alignment conveyor and an alignment moving carriage to an alignment cathode pivot, rotated by the alignment cathode pivot, and inserted into a predetermined electrolytic cell.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
An automatic transferring and processing apparatus of a cathode characterized by comprising a movable means for inserting a blank cathode and taking out a cathode having an electro-deposited metal from an electrolytic cell, a stock cathode pivot, a processing means for processing an electro-deposited metal deposited on said cathode, a stock conveyor for transferring the cathode on said stock cathode pivot to said means for processing the electro-deposited metal, a stock moving carriage for transferring the cathode on said stock cathode pivot to said stock conveyor, an alignment conveyor for receiving the processed cathode from said processing means, an alignment cathode pivot, an alignment moving carriage for transferring the cathode on said alignment conveyor to said alignment cathode pivot, and a guide rail for moving said movable means between said electrolytic cell and said stock cathode pivot and between said electrolytic cell and said alignment cathode pivot.
Claim 2
Dependent Claim
147 words
An automatic transferring and processing apparatus of a cathode characterized by comprising a movable means for inserting a blank cathode and taking out a cathode having an electro-deposited metal from an electrolytic cell, a stock cathode pivot, a processing means for processing an electro-deposited metal deposited on said cathode, a stock conveyor for transferring the cathode on said stock cathode pivot to said means for processing the electro-deposited metal, a stock moving carriage for transferring the cathode on said stock cathode pivot to said stock conveyor, an alignment conveyor for receiving the processed cathode from said processing means, an alignment cathode pivot, an alignment moving carriage for transferring the cathode on said alignment conveyor to said alignment cathode pivot, and a guide rail for moving said movable means between said electrolytic cell and said stock cathode pivot and between said electrolytic cell and said alignment cathode pivot.
Claim 3
Dependent Claim
21 words
The automatic transferring and processing apparatus as claimed in claim 1, wherein said processing means is an electro-deposited metal stripping means.
Claim 4
Dependent Claim
25 words
The automatic transferring and processing apparatus as claimed in claim 1, wherein both said cathode pivots have a means for rotating by at least 180°.
Claim 5
Dependent Claim
36 words
