Abstract
A device for positioning tools such as slitters and scorers used with a corrugating machine is proposed. As a pair of rotary shafts rotate, tool heads mounted thereon and each carrying a tool rotate, so that the tools work the web of corrugated fiberboard fed between them as required. When a transfer unit is operated with the tool head supporting plate coupled with the position adjusting member carrying a tool head, they move together axially along the rotary shafts, so that a pair of the tools will be moved simultaneously to a desired position.
Claims13
A tool positioning device for positioning a plurality of tools for working a running web, said device comprising;
- a pair of rotary shafts arranged one over the other so as to be parallel to each other and to be perpendicular to the direction in which the web runs;
- a plurality of tool heads mounted on each of said rotary shafts so as to be slidable axially thereon and turn together with the rotary shaft;
- said tool heads each being adapted to carry one of the tools;
- a plurality of head supporting plates for supporting said tool heads mounted on one of said rotary shafts so as to allow said tool heads to turn together with said respective rotary shafts;
- a plurality of position adjusting members for supporting said tool heads mounted on the other of said rotary shafts so as to allow said tool heads to turn together with said other of the rotary shafts;
- a transfer means for moving said position adjusting members independently from said head supporting plates along said rotary shaft;
- and
- a plurality of coupling means each for coupling together an opposed pair formed by one of said head supporting plates and one of said position adjusting members, so that said opposed pair will be moved together by said transfer means along said rotary shafts only when said coupling means positively connects said position adjusting means to said head supporting plate.
