An apparatus is disclosed wherein annular articles conveyed one by one to a chute member are successively transferred to a rail member connected to the chute member until a predetermined number of articles are lined up thereon, whereupon a plurality of slender holders waiting their turn above the individual articles are lowered and then lifted in unison, whereby the holders pass through the apertures of the articles in their downward travel and in their upward travel they lift the articles in unison which are held in position as a result of projectable members installed at the front ends of the holders being projected in connection with the upward movement of the holders, the above operation being repeatedly carried out a plurality of times until each holder is loaded with a desired number of articles piled in a stack, the stacks of articles on the individual holders being then released in unison onto a table member, the latter being adapted to be inched each time it receives the stacks so that such articles are piled in a plurality of rows of stacks on the table member. Details of the apparatus will be made clear.
An apparatus for piling apertured annular articles in vertical stacks for storage comprising an elongated, horizontally disposed rail member, means associated with said rail member for conveying a predetermined number of annular articles thereon in longitudinally aligned and successively positioned relationship, a plurality of vertically disposed and vertically reciprocable holder means corresponding in number to the number of apertured articles on said rail member positioned above said rail member with each holder means being adapted to be in vertical alignment with the aperture of an annular article when positioned thereon, each of said holder means having outwardly projectable retaining means adjacent its lower end thereof, actuating means for moving said holding means downwardly and upwardly and to simultaneously move the retaining means inwardly and outwardly respectively whereby each holder means on its downward movement will have its lower end pass through the aperture of a corresponding annular article and on its upward movement the retaining means will be projected outwardly thereby permitting the annular member to be carried upwardly and retained on the holding means, table means positioned below and at right angles to said rail member for receiving a plurality of vertically stacked apertured annular articles thereon from each of said holding means, and drive means for moving said table means at a predetermined time for a distance equal to the outer diameter of an apertured annular article being processed by the apparatus.
An apparatus for piling apertured annular aritcles in vertical stacks for storage comprising an elongated, horizontally disposed rail member, said rail member having a clearance throughout its longitudinal length, a chute member being operatively connected in linear relationship at one end to said rail member and revolving shaft means operatively connected to the other end of said chute means around which the rail member can be swung from an operating position to a stacking position, feeding means for conveying a predetermined number of annular articles from said chute to said rail member in longitudinally aligned and successively positioned relationship, a plurality of vertically disposed and vertically reciprocable holder means corresponding in number to the number of apertured articles on said rail member positioned above said rail member with each holder means being adapted to be in vertical alignment with the aperture of an annular article when positioned thereon, each of said holder means having outwardly projectable retaining means adjacent its lower end thereof, actuating means for moving said holding means downwardly and upwardly and to simultaneously move the retaining means inwardly and outwardly respectively whereby each holder means on its downward movement will have its lower end pass through the aperture of a corresponding annular article and on its upward movement the retaining means will be projected outwardly thereby permitting the annular member to be carried upwardly and retained on the holding means, table means positioned below and at right angles to said rail member for receiving a plurality of vertically stacked apertured annular articles thereon from each of said holding means when said rail member has been swung to a stacking position, and drive means for moving said table means at a predetermined time for a distance equal to the outer diameter of an apertured annular article being processed by the apparatus.
A method for piling apertured annular articles in vertically stacked relationship for storage comprising feeding a predetermined number of apertured articles in a longitudinally aligned horizontally positioned row, one after the other, on rail means, moving a plurality of holding means vertically downwardly to pass through the aperture of and to engage each of said annular articles, withdrawing said holding means upwardly with said annular articles being carried thereby, feeding a second group of apertured annular articles to said rail means, again moving the holding means downwardly and upwardly to engage and remove the second group of apertured annular articles from the rail means, repeating the feeding and withdrawal operation just described until a plurality of apertured annular articles are positioned on said holding means, swinging rail means to one side and thereafter place the plurality of stacks of annular articles on work table means and withdrawing the holding means upwardly leaving a plurality of vertical stacks of apertured articles thereon.
