  • Patent number: 9321600
    Abstract: A convey mechanism is a moving mechanism used to move a rack, which can store cuvettes, along a linear moving direction. A driving unit drives the convey mechanism to intermittently move the rack along. A detection unit outputs an error signal when it detects that a placement state of the rack on the convey mechanism corresponds to an error placement which does not allow the convey mechanism to normally convey the rack, and does not output any error signal when it detects that the placement state does not correspond to the error placement. A controller controls the driving unit to stop a convey operation of the rack when the error signal is output. The controller controls the driving unit to execute the convey operation of the rack when the error signal is not output.

The lumber pieces are fed by dogs from a start position to a feed position in alignment with a feed conveyor which feeds such pieces longitudinally through a lumber edger with adjustable cutting saws. The feeding mechanism includes alternating sets of first and second dogs which are pivoted between a raised position for engagement with the rear edges of the lumber pieces to push such pieces from the start position to the feed position and a retracted position to enable the dogs to be returned to the start position passing on opposite sides or on the same side of the piece. Electrical actuation motors or fluid cylinder actuation motors with rotating output gears are used to pivot the dogs in response to a control signal produced by an electrical control system.
