Abstract

In a veneer dewatering apparatus, a clutch 30 is arranged on a power transmission path between upper and lower rolls 4, 6 and rotating shafts 20. When a veneer portion without a part such as a knot having extremely high compressive strength compared to the other parts passes between the upper roll 4 and the lower roll 6, or when a veneer passes between the upper roll 4 and the lower roll 6 with no foreign matter such as dust interposed between the upper and lower rolls 4, 6 and the veneer, the clutch 30 connects the upper and lower rolls 4, 6 to the rotating shafts 20. When a veneer passes between the upper and lower rolls 4, 6 with a knot and other foreign matters intervening, the connection between the upper and lower rolls 4, 6 and the rotating shafts 20 by the clutch 30 is released.

Claims16

Dependent claims

A veneer dewatering apparatus for removing water from a veneer, the apparatus comprising:

a frame;
a first roll rotatably supported by the frame;
a second roll rotatably supported by the frame and disposed parallel to the first roll at a distance smaller than a thickness of the veneer from the first roll;
and
a rotation driving unit configured to drive to rotate at least one of the first and second rolls, wherein
the first and second rolls, at least one of which is driven by the rotation driving unit, each include a shaft rotatably supported by the frame, a cylinder disposed coaxially with the shaft on the outer periphery of the shaft, an elastic cylindrical member arranged integrally on the outer periphery of the cylinder and coaxially with the shaft, and a connecting unit positioned in a power transmission path between the shaft and the cylinder, and wherein
the connecting unit is configured to connect the shaft and the cylinder to rotate them integrally when the elastic cylindrical member contacts the veneer in a first state, and release the connection between the shaft and the cylinder to rotate them relative to each other when the elastic cylindrical member contacts the veneer in a second state.
