Abstract
A saw changer for changing a saw assembly mounted on an arbor of a saw machine. A carrier is positioned for powered sliding movement axially along the saw assembly from a position under the arbor to a position free of the arbor. The carrier includes holders that are raised into position for holding the saw assembly and through powered axial movement of the carrier, for removing the saw assembly from the arbor. Upon removal, the saw assembly is lifted from the carrier and a replacement saw assembly is mounted on the carrier for placement onto the arbor.
Claims7
A mechanized saw assembly changer for a sawing machine comprising:
- a saw assembly removably mounted to an arbor on the saw machine and a motor rotatably driving the arbor from one end, and a removable support supporting the arbor on an opposite end;
- a movable carrier movable between a first position under the saw assembly mounted to the arbor and a second position out from under the arbor at said opposite end;
- a first power source powering the movement of the movable carrier between said first and second positions;
- holders movably mounted on said carrier and movable between a raised position in contact with a saw assembly mounted on the arbor and a retracted position away from the saw assembly;
- and
- mechanism for raising the holders of the carrier to the second position with the carrier in the first position and thereby controllably mounting the saw assembly to the carrier, a control for moving the carrier and assembly to the second position and thereby exposing the saw assembly for replacement.
A process for changing a saw assembly mounted on an arbor of a saw machine and rotatively supported at its ends, said process including:
- providing a carrier including holders adapted to carry the saw assembly;
- placing the carrier under the saw assembly;
- raising the holders into engagement with the saw assembly;
- removing one end support from the arbor;
- moving the carrier and saw assembly along the arbor and off the end having the end support removed;
- and
- removing the saw assembly from the carrier and replacing it with a replacement saw assembly for placement on the arbor.
