Abstract
A battery grid pasting machine has an endless steel conveyor belt for advancing grids beneath a paste hopper. The lower end of the hopper is closed by an orifice plate. The top run of the belt is supported by a vertically adjustable roller directly beneath an orifice slot in the orifice plate. A guide assembly is provided for advancing the grids in a downwardly inclined position toward the underside of the hopper. The hopper and the belt conveyor assembly are supported from one side of the machine in cantilever fashion which enables the hopper and the endless belt to be removed and replaced with a minimum dismantling of components of the machine.

A battery grid pasting machine having a conveyor, an endless metal belt carried by said conveyor and having a top run with a generally horizontally extending outer face on which battery grids are adapted to be supported and conveyed in one direction, a belt support roller on the underside of and supporting the top run of the belt, a paste hopper having an orifice plate spaced above the belt and overlying said belt support roller, said orifice plate having an orifice slot therethrough which overlies and extends transversely across the belt, means in the hopper for feeding paste downwardly through said orifice slot at a predetermined rate, the entire bottom of said orifice plate being spaced throughout from and above the outer face of the underlying portion of the top run of said belt to provide a clearance therebetween at least slightly greater than the thickness of the grid to be pasted, said bottom of the orifice plate having a portion adjacent and downstream of the orifice slot which is spaced from and above the outer face of the underlying portion of the top run of said belt so that there is a clearance therebetween slightly greater than the thickness of the grid to be pasted for controlling the thickness of the paste applied to the grid, at least a portion of the bottom of said orifice plate adjacent to and upstream of said orifice slot being spaced from and above the outer surface of an underlying portion of the top run of said belt such that there is a clearance therebetween greater than said clearance between said bottom portion downstream of said orifice and its associated underlying portion of the top run of said belt, said orifice slot having an upstream edge located at least slightly upstream from the uppermost portion of said belt support roller and guide means constructed and arranged to guide a grid between said belt and said orifice plate at an angle inclined to the outer surface of at least a portion of the top run of said belt adjacent to and upstream of said orifice slot so that as such grid passes beneath the orifice slot the face of such grid adjacent said belt is spaced slightly from and above the outer surface of the immediately underlying portion of the top run of said belt to provide a clearance therebetween such that paste being fed from said orifice slot passes through the grid and enters into such clearance, whereby both faces of the grid are covered with paste and the grid is overpasted.
A battery grid pasting machine comprising a frame, a conveyor supported on said frame and having an endless belt with a generally horizontally disposed top run, a support shaft on said frame extending transversely across the belt, a paste hopper slidably received and supported on said support shaft, pivotable about the axis of said support shaft from an operative position upwardly to a servicing position and slidably removable from said support shaft, said support shaft being supported at one end in cantilever fashion on said frame, a plurality of rotary paste feeding members in said hopper mounted on shafts generally parallel to the support shaft, a first drive member on the support shaft, second drive members on the shafts of the paste feeding members, a drive train connecting said first and second drive members to rotate the paste feeding members in response to rotation of the first drive member, a third drive member on said hopper support shaft, a motor having a driving connection with said third drive member, said first and third drive members being drivingly connected and journaled for rotation on said support shaft adjacent said one end thereof and said hopper being axially slidable off said support shaft in the direction toward the opposite end of said support shaft, whereby said hopper can be removed from the machine.
A battery grid pasting machine comprising a lower frame and an upper frame, said upper frame being supported at one side thereof on the lower frame in cantilever fashion such that the bottom of the upper frame is spaced above the top of the lower frame at the other side thereof, a pair of rollers journalled on said top frame about generally parallel axes which extend transversely of the sides of the frame, the top of each roller projecting above the top of the upper frame and the bottom of each roller projecting below the bottom of the upper frame and above the top of the lower frame at said other side of the frames, the outer surface of one roller projecting radially outwardly beyond one end of the top frame and the other roller projecting radially outwardly beyond the other end of the upper frame whereby each roller is axially unobstructed around at least 180.degree. by said upper and lower frames and a conveyor belt trained around said rollers, the top and bottom runs of said belt between said rollers registering horizontally with the spaces above and below said top frame at said other side thereof.
A battery grid pasting machine comprising;
- a conveyor, an endless belt carried by said conveyor and having a top run with a generally horizontally extending outer surface, a paste hopper above the top run of the belt and having an orifice plate with an orifice slot therethrough and extending transversely of and overlying the top run of said belt, a paste delivery means in said hopper for feeding paste through said orifice slot at a predetermined rate, the bottom of the entire orifice plate being spaced throughout from and above the outer surface of the underlying portion of the top run of said belt so that there is a clearance therebetween which is at least slightly greater than the thickness of the grid to be pasted, a bottom portion of said orifice plate adjacent to and downstream of the orifice slot being spaced from and above the outer surface of the underlying portion of the top run of said belt so that there is a clearance therebetween only somewhat greater than the thickness of the grid to be pasted for controlling the thickness of the paste applied to the grid, a bottom portion of said orifice plate adjacent to and upstream of said orifice slot being spaced from and above the outer surface of an underlying portion of the top run of said belt such that there is a clearance therebetween greater than such clearance between said bottom portion downstream of said orifice slot and its associated underlying portion of the top run of said belt, and guide means constructed and arranged to guide a grid between said belt and said orifice plate at an angle inclined to the outer surface of at least the portion of the top run of said belt adjacent to and upstream of said orifice slot, such that as the grid passes beneath said orifice slot, the face of such grid adjacent said belt is slightly spaced from and above the outer surface of the immediately underlying portion of the top run of said belt to provide a clearnace therebetween so that paste being fed from said orifice slot passes through the grid and enters into such clearance, whereby both faces of the grid are covered with paste and the grid is overpasted.
A battery grid pasting machine comprising a frame, a conveyor mounted on said frame and having an endless metal belt with a generally horizontally extending rop run with an outer surface on which a battery grid is adapted to be supported and conveyed in one direction, a belt support roller on the underside of and supporting the top run of the belt, a paste hopper above the belt and having an orifice plate having an orifice slot therethrough which overlies and extends transversely across the belt, means in the hopper for feeding paste downwardly through said orifice slot at a predetermined rate, the entire bottom of the orifice plate being spaced throughout from and above the outer surface of the underlying portion of the top run of the belt to provide a clearance therebetween at least slightly greater than the thickness of the grid to be pasted, a bottom portion of said orifice plate adjacent to and downstream of the orifice slot being spaced from and above the underlying outer surface of the top run of the belt to provide a clearance greater than the thickness of the grid to be pasted for controlling the thickness of the paste applied to the grid, a bottom portion of said orifice plate upstream of and adjacent to said orifice slot being spaced from and above an underlying portion of the outer surface of the top run of the belt to provide a clearance therebetween greater that such clearance between said portion downstream of said orifice slot and said top run of said belt such that the grid can be inclined therein to the top run of the belt, guide means for guiding a grid into the clearance between said bottom portion of the orifice plate upstream of the orifice slot and the underlying outer surface of the belt at an inclinded angle to such outer surface of the top portion of the belt upstream of said orifice slot so there is clearance between the lower face of the grid and the underlying top portion of the belt into which paste is fed when the grid passes under the orifice slot so that paste is applied to both faces of the grid and the grid is overpasted, and means for raising and lowering said belt support roller to thereby vary the extent of said clearances, whereby the machine can be adjusted to vary the extend of the overpasting of the grids and to accommodate runs of grids of differing thickness.
