Abstract
A ring flaker has a housing with a back opening so that a blade ring mounted to an arbor assembly can be slid backwards away from the housing to allow the blade ring to be replaced without removing the housing. This arrangement reduces the down time generally necessary to replace a blade ring in a ring flaker. The back opening in the housing is of sufficient size to permit the blade ring to be axially withdrawn. The arbor assembly has a slide arrangement on the ring flaker carriage and there is provision to use a hydraulic jack to move the arbor assembly on the slide arrangement for a distance sufficient for the blade ring to be disconnected for removal and replacement.
Claims11
In a ring flaker apparatus for cutting wood into wood flakes including:
- a housing having a front opening for insertion of wood to be flaked;
- a blade ring within the housing encompassing a wood chamber, the blade ring having a plurality of knife blades spaced apart around the ring;
- a hub disc attached to the blade ring, the hub disc cantilevered on an arbor rotating about a rotational axis, supported by an arbor support outside the housing;
- drive means to rotate the arbor, hub disc and blade ring;
- carriage on which the arbor support is mounted, and
- means to move the carriage in a direction perpendicular to the rotational axis;
- the improvement to remove and replace the blade ring comprising:
- back opening in the housing of sufficient size to permit the hub disc and the blade ring to axially move out of the housing;
- arbor support slide means to permit axial movement of the arbor support on the carriage in a direction away from the housing so the blade ring and hub disc pass through the back opening in the housing, and
- means to slide the arbor support for a distance sufficient for the blade ring to be disconnected from the hub disc and lifted up for removal and replacement.
