Abstract
Abstract A grid feeder device for storage battery grids or plates comprises a pivotally oscillating bellcrank-like member and associated grid stop means and grid guiding means which, with pickup disks, are interposed between input and output conveyors. The input conveyor consists of a pair of continuously orbiting endless flexible conveying elements or chains upon which a plurality of grids are supported in substantially vertical orientation, the continuous movement of the conveying elements tending to maintain such grids closely packed together and for urging the leading or forward several of the grids onto a support edge of the oscillating member when the latter is in its lower and rearwardmost position and against an abutment thereon. The support edge of the oscillating member periodically moves forwardly and upwardly carrying the several grids therewith and moving the forwardmost one of the grids into the path of a tooth on the rotating pickup disk, which rotates in synchronism with the oscillating member. The grid stop means limit the forward movement of the forwardmost grid so that only that grid is picked up by the tooth on the rotating pickup disk. As the forwardmost grid is lifted from the support edge of the oscillating member by the rotating pickup disk, the grid guiding means urges same firmly against the surface of the pickup disk above the tooth thereon and the support edge of the oscillating member returns downwardly and rearwardly to its original position for receiving an additional grid or grids from the input conveyor to repeat the above mentioned cycle of operation. In the meantime, the rotating disk transfers the aforementioned forwardmost grid to the output conveyor, the speed of the output conveyor being adjusted with respect to the speed of the rotating disk and oscillating member so that grids will be placed on the output conveyor in a horizontal and close spaced condition to allow further operations to be carried out thereon, such as a grid pasting operation.
