Abstract
Abstract On an upper table and a lower table arranged to rotate simultaneously about a center axis thereof, plural pairs of upper and lower presses are concentrically arranged and operated in accordance with a predetermined time sequence. The upper and lower presses have press heads for holding a battery cover and a battery container. Between one of the paired upper and lower press heads is disposed means for furnishing a bonding medium such as heat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
178 words
In apparatus for bonding a cover member of a storage battery to a battery container, comprising: an upper table and a lower table arranged to rotate simultaneously about a center axis thereof; a plurality of upper press means concentrically arranged on said upper table with respective press heads projecting below said upper table, each of said press heads having means for lifting said battery cover; a plurality of lower press means concentrically arranged on said lower table with respective press heads projecting above said lower table to face with said press heads of saId upper press means, each of said press heads of said lower means having means for setting the battery container to a predetermined position; means for operating both of said upper and lower press means in accordance with a predetermined time sequence; and stationary plate means for contacting at least one of the bonding faces of said battery cover and container by which said face is rendered capable of bonding, said plate means being disposed between one of the paired upper and lower press heads.
Claim 2
Dependent Claim
178 words
In apparatus for bonding a cover member of a storage battery to a battery container, comprising: an upper table and a lower table arranged to rotate simultaneously about a center axis thereof; a plurality of upper press means concentrically arranged on said upper table with respective press heads projecting below said upper table, each of said press heads having means for lifting said battery cover; a plurality of lower press means concentrically arranged on said lower table with respective press heads projecting above said lower table to face with said press heads of saId upper press means, each of said press heads of said lower means having means for setting the battery container to a predetermined position; means for operating both of said upper and lower press means in accordance with a predetermined time sequence; and stationary plate means for contacting at least one of the bonding faces of said battery cover and container by which said face is rendered capable of bonding, said plate means being disposed between one of the paired upper and lower press heads.
Claim 3
Dependent Claim
92 words
An apparatus as claimed in claim 1, further comprising a conveyer means for feeding the battery cover and container onto said lower press head, a delivery means for discharging said battery cover and container from said lower press head, said conveyer means and delivery means being disposed adjacent to the periphery of said lower table with an angular interval about the center axis thereof, and means for intermittently rotating said upper and lower table to locate circumferentially adjacent two lower press heads closely to said conveyer means and delivery means in turn.
Claim 4
Dependent Claim
90 words
An apparatus as claimed in claim 1, wherein said press operating means is an air sequential control system comprising a compressed air feeding pipe extending through a stationary shaft along the center axis of said tables, a rotary cylinder hermetically enclosing said stationary shaft and rotatable thereabout together with said tables, said compressed air feeding pipe being open in said rotary cylinder, and a number of flexible pipes and air valves through which the compressed air is fed into each of said presses from said rotary cylinder under sequential control.
Claim 5
Dependent Claim
39 words
An apparatus as claimed in claim 1, wherein said battery cover and container are made of thermoplastic resin, and said bonding medium furnishing means is a thermoplate against which bonding faces of said battery cover and container are pressed.
Claim 6
Dependent Claim
48 words
An apparatus as claimed in claim 1, wherein said bonding medium furnishing means is a spongy plate on which an adhesive or solvent is supplied through a stationary shaft at the axial center of the tables and with which bonding faces of said battery cover and container contact.
