Abstract
A method and apparatus for applying paste to battery grids wherein the paste is circulated in a primary circuit incorporating an open reservoir wherein the paste is relieved of all pumping pressure and portion of the paste is diverted from the primary circuit into a secondary circuit for delivery to a nozzle which may be selectively opened and closed to deliver paste to the grid, the secondary circuit also incorporates the open reservoir.
Claims9
A method of applying paste to a battery grid comprising circulating paste in a primary circuit, diverting the paste from a primary circuit into a secondary circuit, selectively diverting a quantity of paste from the secondary circuit through a nozzle, passing battery grids in sequence beneath the nozzle and timing the diversion of the paste through the nozzle relative to the passage of the grid beneath the nozzle to deliver the quantity of paste onto a predetermined area of each grid as it passes beneath the nozzle.
A method of applying paste to a battery grid comprising drawing paste from a paste reservoir by a primary pump, circulating paste by said primary pump through a primary circuit terminating at said reservoir, diverting paste from said primary circuit by a secondary pump into a secondary circuit terminating at said reservoir, independently diverting paste from said secondary circuit through a plurality of nozzles for delivery to a battery grid, passing battery grids in sequence beneath the nozzles and timing the diversion of the paste through the nozzles relative to the passage of the grid beneath the nozzles to selected predetermined areas of each battery grid as it passes between the nozzles.
In apparatus for applying paste to battery grids:
- a primary paste pump arranged to circulate paste in a primary circuit, at least one secondary pump arranged to divert paste from the primary circuit to a secondary circuit, at least one nozzle means in paste receiving communication with said secondary circuit, and means operable to control the dispensing of a quantity of paste from said nozzle means, conveyor means to carry battery grids in sequence beneath said nozzle means, and means to regulate the operation of the control means in response to the dispensing of paste through the nozzle means relative to the passing of the grids there beneath so a measured quantity of paste is delivered for said nozzle means onto a predetermined area of each grid as said grid passes beneath said nozzle means.
In apparatus for applying paste to a battery grid, a paste reservoir, a primary paste pump arranged to circulate paste in a primary circuit incorporating said reservoir, at least one secondary paste pump arranged to divert paste from the primary circuit into a respective secondary circuit terminating at said reservoir, and a plurality of nozzles communicating with said secondary circuit, a conveyor arranged to support a plurality of battery grids and operable to move each grid in sequence beneath each nozzle, and means to selectively open and close each nozzle in response to the movement of the grid beneath the respective nozzles to deliver paste from the secondary circuit to selected predetermined areas of the battery grid.
