Abstract
A system and method for replacing or substituting mold blocks in a corrugator, the corrugator comprising first and second tracks for carrying respective chains of mold blocks, each of the tracks comprising return tracks, wherein the system advances replacement mold blocks towards the return tracks to displace corresponding mold blocks in the mold block chains while the corrugator is in production and while the mold block chains are in motion.
Claims12
An apparatus for mold block exchange on a corrugator, the corrugator having a frame and a first track for carrying a plurality of first mold blocks and a second track for carrying a plurality of second mold blocks, the first and second tracks being generally parallel with each other, each of the first and second tracks comprising a respective production track and a respective return track, wherein the apparatus comprises:
- a pair of first rails secured to the first track, the first rails being generally parallel to the first track and provided on opposite sides thereof;
- a pair of second rails secured to the second track, the second rails being generally parallel to the second track and provided on opposite sides thereof;
- a first table aligned with the first return track and being moveably supported by the first rails;
- a second table aligned with the second return track and being moveably supported by the second rails;
- each of the first and second tables comprising a respective pair of staging platforms provided on opposite sides of the respective first return track and second return track, each of the staging platforms being aligned with the respective return tracks and being adapted to support one or more replacement mold blocks;
- each of the staging platforms including a push arm adapted to advance the one or more replacement mold blocks and to load the one or more replacement mold blocks on to the respective return track.
A method of exchanging mold blocks provided on a corrugator, the corrugator having a first track for carrying a first mold block chain comprising a plurality of first mold blocks and a second track for carrying a second mold block chain comprising a plurality of second mold blocks, the first and second tracks being generally parallel with each other, each of the first and second tracks comprising a respective production track and a respective return track, wherein the method comprises:
- staging one or more first replacement mold blocks adjacent to the first return track and on a first staging surface aligned with the first return track and wherein the first staging surface is moveably supported by a pair of first rails secured to opposite sides of the first track and being generally parallel with the first track;
- staging one or more second replacement mold blocks adjacent to the second return track and on a second staging surface aligned with the second return track and wherein the second staging surface is moveably supported by a pair of second rails secured to opposite sides of the second track and being generally parallel with the second track;
- advancing the first and second replacement mold blocks towards the first and second return tracks to displace corresponding mold blocks on the first and second mold block chains;
- wherein the mold block displacement is conducted while the mold block chains are in motion.
