An apparatus for automatically wrapping a plate for use in a lead acid industrial storage battery, said wrapping comprising a combination of three acid resistant, flexible porous materials forming an envelope adapted to insulate said plate while allowing free access of the battery acid to the surfaces of said plate. As configured, the wrapping apparatus comprises a plurality of regularly spaced, heated die fixtures attached to a servo controlled turntable, said turntable acting to index said dies through a set of six fixed work stations which are disposed on said apparatus around the periphery of said turntable. The six work stations of the apparatus are adpated to feed each of the three wrapping materials and a plate into one of said dies, wrap the materials around the plate, seal the edges of the outermost of said three wrapping materials, discharge the wrapped plate for further processing and measure the temperature of the heated die before it is recycled through the apparatus. In the present configuration, the apparatus is adapted to produce a wrapped plate, every six to eight seconds.

Wrapping apparatus for industrial battery plates

A novel industrial battery stack is disclosed, wherein positive plates which have been longitudinally wrapped with a perforate or semi-perforate material are accurately aligned with respect to the negative plates and separators in the stack during the stacking operation. The novel spacing members of the present invention have a generally U-shaped cross section for engaging through the wrapping a portion of the positive plate adjacent to the longitudinal edges of that plate. Projections protruding substantially from the base of the 'U' provide the proper distance between the edge of the wrapped plate and an adjacent longitudinal surface. During the stacking and burning operation, this longitudinal surface comprises the back wall of a novel industrial battery plate holder. Following the burning of the battery stack and its subsequent assembly into an appropriate industrial battery case, the spacing member or members act to protect the positive battery plates and retain them in their proper alignment during the operation of the battery. Applicants have also provided a novel apparatus and method for stacking, aligning and burning industrial battery stacks which comprises a battery stack holder having several upstanding walls which define a stacking column having a coplanar terminus. An adjustably locatable partition within said stacking column may be disposed at any of a plurality of positions parallel with respect to the coplanar terminus so that the battery stack holder may be adjusted for any of a variety of given sizes of plates and separators. The battery plates and separators may then be stacked into the battery stack holder so that only the plate lugs extrude beyond the coplanar terminus. A dam is insertable along the top of the battery plates and across the top of the upstanding side walls of the battery stack holder to facilitate the rapid efficient burning of the industrial battery stack. This method is enhanced by the prior axial compression of the battery stack which effectively reduces the volume of the stack, and consequently the size of the industrial battery case required to contain a given amount of active battery material.

Industrial battery stack

Industrial battery stack, and apparatus and method for stacking,

A novel system for assembling industrial or motive power batteries is described which basically comprises a conveyor surface, a plurality of stacking box means freely movable across said conveyor surface, tilt table means for engaging in tilting said stacking box, and a novel burning apparatus for forming battery straps on any of a plurality of different sized battery stacks formed within said stacking box means. Additionally, a novel automated burning apparatus is provided wherein a plurality of torches are adapted for a square movement across the terminal lugs of the battery stack, thereby facilitating the formation of battery straps and terminal posts on each of a plurality of battery stacks during a single operation. Utilization of the present system facilitates the efficient manufacture of industrial or motive power batteries of any of a number of different sizes.
