Abstract
A plurality of upper spool rails arranged over a reel-up device. Each elevated rail temporarily stores reeling spools that are successively loaded into a reeling station to wind a web and form finished reels of paper. The elevated spool rails include: a first pair of parallel upper spool rails extending over the reel-up device and adapted to support a plurality of a first type of reeling spools; and a second pair of parallel upper spool rails spaced above the first pair, and adapted to a plurality of a second type of reeling spools.
Claims27
A plurality of upper spool rails elevated for a reel-up device for temporarily storing reeling spools before being successively loading into a lower reeling station of the reel-up device, the spool rails comprising:
- a first elevation of an upper spool rail elevated higher than the reeling station of the reel-up device and adapted to support a plurality of reeling spools;
- a second elevation of an upper spool rail above the first elevation and adapted to support a plurality of reeling spools, wherein the reeling spools on the first elevation and the second elevation have no wound web, and
- a spool lowering assembly adjacent the reeling station and adapted to lower a first selected reeling spool to the reeling station from the first elevation and a second selected reeling spool to the reeling station from the second elevation.
A method for temporarily storing reeling spools and loading the spools into a reeling station of a reel-up device, said method comprising:
- a. storing a first group of the reeling spools on a first spool rail elevation higher than the reeling station;
- b. storing a second group of the reeling spools on a second spool rail elevation higher than the reeling, wherein the second spool rail is at least partially over the reeling station and above the first rail elevation;
- c. selecting a first reeling spool from a first one of the spool rail elevations;
- d. lowering the selected first reeling spool to receive a web and engage the reeling station;
- e. winding the web onto the selected first reeling spool to form a web roll
- f. selecting a second reeling spool from a second one of the spool rail elevations;
- g. lowering the selected second reeling spool to receive a web an engage the reeling station, and
- h. winding the web onto the selected second reeling spool to form a web roll.
A web reeling device comprising:
- a reeling station comprising a rotating cylindrical drum arranged to engage a web;
- a spool lowering assembly adjacent the reeling station and adapted to lower a selected reeling spool to the reeling station, such that the web is sandwiched between the spool and the cylindrical drum;
- a first spool rail elevation higher than the reeling station and comprising a spool rail adapted to support a plurality of reeling spools, wherein the reeling spools have no wound web, and
- a second spool rail elevation above the first elevation and comprising a spool rail adapted to a support a plurality of reeling spools, wherein the reeling spools have no wound web, and
- further wherein the spool lowering assembly lowers a selected reeling spool to the reeling station from the first spool rail elevation and lowers another selected reeling spool to the reeling station from the second spool rail elevation.
