Abstract
Abstract This invention relates to a plate wrapping machine for storage batteries. It comprises an embosser for embossing a flat microporous sheet pulled from a supply reel to obtain a storage battery separator, a plate projector for separating and projecting plates one by one out of a hopper, a separator supplier for supplying the above mentioned embossed separator so as to intersect rectangularly with the projected plate and a separator sealing means for sealing the side parts of the embossed separator folded into two to wrap the plate, and wherein the respective components are operatively connected with one another in an on-line operation. The present invention has an advantage that a storage battery plate can be wrapped with an embossed separator quickly at a high efficiency by saving labor so that the cost of the product may be reduced.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A storage battery plate wrapping machine, comprising: means for embossing a flat microporous sheet fed from a supply reel to obtain embossed separator material in a continuous length; a separator feeding means for feeding said embossed separator material; transport means for transporting the embossed separator from said embossing means to said separator feeding means and including means for detecting the length of separator between said embossing means and said separator feeding means, and means responsive to said means for detecting for controlling the length of separator between said means for embossing and said separator feeding means; means for cutting said separator; a plate separating and delivering means for separating and delivering plates from a hopper to fold the cut separator material about a delivered plate; and means for joining the parts of the separator about an individual plate therein.
Claim 2
Dependent Claim
139 words
A storage battery plate wrapping machine, comprising: means for embossing a flat microporous sheet fed from a supply reel to obtain embossed separator material in a continuous length; a separator feeding means for feeding said embossed separator material; transport means for transporting the embossed separator from said embossing means to said separator feeding means and including means for detecting the length of separator between said embossing means and said separator feeding means, and means responsive to said means for detecting for controlling the length of separator between said means for embossing and said separator feeding means; means for cutting said separator; a plate separating and delivering means for separating and delivering plates from a hopper to fold the cut separator material about a delivered plate; and means for joining the parts of the separator about an individual plate therein.
Claim 3
Dependent Claim
23 words
A wrapping machine as in claim 1 wherein said means for controlling controls both said means for embossing and said separator feeding means.
Claim 4
Dependent Claim
60 words
A wrapping machine as in claim 1 or 2 wherein said means for detecting detects at least a minimum and maximum length of said separator material, and said means for controlling controls said embossing means or said separator feeding means in dependence upon detection by said detecting means of said at least minimum and maximum length of separator material, respectively.
Claim 5
Dependent Claim
79 words
A wrapping machine as in claim 3 wherein said transport means includes a pair of nipping rollers for receiving said separator material from said means for embossing and a guide roller for transporting said separator material from said nipping rollers by forming a sag in the separator material between said nipping rollers and said guide roller, and said means for detecting includes sag detector elements for detecting said at least minimum and maximum sag of said separator material, respectively.
Claim 6
Dependent Claim
76 words
A wrapping machine as in claim 1 wherein said means for embossing includes an embossing roll and an elastic roll mounted in movable relationship to one another, means for pressing said embossing roll and elastic roll into pressing relationship with one another, said embossing roll including projections on the surface thereof, and means for rotating said embossing roll for feeding said flat microporous sheet from said supply reel and between said embossing roll and elastic roll.
Claim 7
Dependent Claim
27 words
A wrapping machine as in claim 5 wherein said embossing means further includes means for heating said embossing roll and means for cooling the embossed separator material.
Claim 8
Dependent Claim
60 words
A wrapping machine as in claim 6 wherein said means for cooling includes a pair of spaced cooling rollers and said means for embossing further includes means for driving at least one of said cooling rolls for transporting the embossed separator material from said embossing roll and elastic roll through said spaced cooling rollers under low tension without substantial deformation.
Claim 9
Dependent Claim
79 words
A wrapping machine as in any of claims 5, 6 or 7 wherein said means for detecting detects at least a minimum and maximum length of said separator material and said means for controlling includes means for deactuating said means for rotating said embossing roll upon detection of said at least minimum length, and for deactuating said pressing means to enable said embossing roll and said elastic roll to separate from one another upon detection of said minimum length.
