Abstract
A method and apparatus of buffering sheets of cut stock in block-shaped stacks ranged in rows between stock-cutting machinery and further processing machinery, whereby each row is also block-shaped. Each row produced by the cutting process is forwarded to a buffer's intake and thence to a marshaling area where it is combined with previously forwarded rows into a group. Each group is forwarded to the buffer's outtake and combined with any other rows already there. The most downstream row of the group is forwarded to the further-processing machinery.
Claims19
A method for buffering sheets of cut stock in block-shaped stacks positioned in rows between stock-cutting machinery and further processing machinery, each of said rows being also block-shaped, the method comprising the steps of:
- forwarding each row produced by a discontinuous cutting process to a buffer's intake;
- forwarding thereafter said each row to a marshaling area where said each row is combined with previously forwarded rows into a group;
- forwarding each said group to a buffer's outtake and combining each said group with any other rows already there and
- forwarding the most downstream row of the group to the further processing machinery for continuous processing of said downstream row, rows of stacked sheets for cutting being buffered for continuous processing in said further processing machinery after being discontinuously cut in said stock cutting machinery, a plurality of stacks impinging on the cutting process in a row and leaving the cutting process discontinuously due to a time interval between each cutting step, a plurality of stacks forming a group inside said buffer.
Apparatus for buffering sheets of cut stock in block-shaped stacks positioned in block-shaped rows between stock-cutting machinery and further processing machinery, comprising:
- a buffer with a counter accommodating the stacks;
- first means for forwarding each row of stacks produced by the cutting process along the counter in a first direction;
- second means for forwarding the row already forwarded by said first means along the counter in a second direction perpendicular to said first direction;
- third means for forwarding the group of rows or combined group of rows along said counter in said second direction, paths traveled by said second and said third means overlapping;
- and
- fourth means for forwarding the frontmost row from said counter to said further-processing machinery in a direction perpendicular to said second direction.
A method for buffering sheets of cut stock in block-shaped stacks positioned in rows between stock-cutting machinery and further processing machinery, each of said rows being also block-shaped, the method comprising the steps of:
- forwarding each row produced by a discontinuous cutting process to a buffer's intake;
- forwarding thereafter said each row to a marshaling area where said each row is combined with previously forwarded rows into a group;
- forwarding each said group to a buffer's outtake and combining each said group with any other rows already there and
- forwarding the most downstream row of the group to the further processing machinery, the row produced by a specific cutting process is electrostatically block-formed before the row is forwarded to the buffer's intake.
