  • Patent number: 10232453
    Abstract: A system, apparatus and method for cutting battery grids or plates from a continuous strip of a plurality of connected battery grids. The continuous strip moves toward a rotating cutter with at least two cutter blades with cutting edges equally circumferentially spaced apart and extending parallel to the cutter axis of rotation and a rotating cooperating anvil. The cutting edges and the anvil are rotated at the same tangential speed to cut in a nip between them a plate or grid from the continuous strip of connected grids. At a point upstream of the cutter, an electric signal indicative of each lug of the grid of the continuous strip moving past this point is used to control the speed of movement of the strip through the nip to cut a plate or grid from the continuous strip at a longitudinal speed which is essentially the same as the tangential speed of the cutting edges.

  • Patent number: 9744552
    Abstract: A battery grid pasting system includes a battery grid pasting machine, a sensing station, and a controller. The battery grid pasting machine includes a conveying apparatus confronting a hopper's dispensing end across a space, and includes a motor actuatable to cause variance of the space and hence variance of the amount of battery paste received on carried battery grids through the space. The sensing station senses a value of a property of a pasted battery grid. And the controller receives the sensed value of the property and controls actuation of the motor based in part or more on the received value.

  • Patent number: 9437867
    Abstract: A battery plate grid strip pasting assembly can include an orifice plate, a support structure, and a belt. The orifice plate has an opening through which battery paste material is dispensed out of a hopper. The support structure underlies a battery plate grid strip and supports the battery plate grid strip upstream of the opening. The belt traverses beneath the orifice plate and carries the battery plate grid strip downstream of the opening and downstream of the support structure. The support structure supports the battery plate grid strip above the belt and a gap is provided between a bottom surface of the battery plate grid strip and a top surface of the belt. Battery paste material is dispensed into the gap, through the battery plate grid strip, and overpastes the bottom surface of the battery plate grid strip.

  • Patent number: 5494400
    Abstract: Apparatus for transporting and stacking battery plates in which pasted battery plates are delivered from a drying oven to a stacking station by an entry conveyor. In the stacking station, a stack of battery plates builds up on a stacking elevator which then deposits the stack on a take-off conveyor. The take-off conveyor indexes, moving the stack of battery plates out of the stacking station to make room for the next stack. A change elevator moves into the stacking station to handle incoming battery plates while the stacking elevator deposits a stack on the take-off conveyor and the take-off conveyor indexes to remove the stack. A partial stack of battery plates accumulates on the change elevator. When the previous stack has been removed from the stacking station, the partial stack is transferred from the change elevator to the stacking elevator, a full stack builds up on the stacking elevator and the cycle repeats.

  • Patent number: 5099982
    Abstract: Apparatus for piling in stacks a plurality of successive individual battery plates moving at a high rate of speed. Synchronized plates are transferred to a carrier conveyor which advances them into work stations with the leading edge of each plate raised generally vertically above its trailing edge. Sequentially in one and another of the stations, each plate is rapidly stopped so that a plurality of succeeding synchronized plates are each disengaged from the carrier and deposited in a stack on an elevator underlying each station. The elevator is retracted as each plate is deposited so that the next plate can be received on the stack. Periodically, the depositing of plates is switched from one station to another and stacks of plates are removed from the elevator associated with each station so that another stack can be formed on the elevator.
