Auto Rotation Log Turner
Main Frame and Slide
Shafts: Cone employs heavy wall square and rectangular steel
tubing in the construction of log turner frames. Tubes are extensively
braced with plates in all high-stress areas. Mounting pads with leveling
screws are provided. Slide shafts are 4� diameter, chrome plated. Slide
bushings are long-lasting hard bronze, protected by rod scrapers.
Spike Rolls: The turning rolls
are one piece held on the axle shaft by Ringfeder locking assemblies. The
spikes are screw-in style and may be purchased in hardened or chromed
versions. As with all of Cone equipment, ease of maintenance is a driving
factor in the design process. Here, one man with an impact wrench can change
all of the spikes with the roll still mounted in the machine in a fraction
of the time it takes to change conventional weld-on spikes.
Spike Roll Drives: The spike
rolls are direct driven, usually with 7.5 HP TEFC motors and Rex reducers.
Roll Closing Cylinders: The spike
roll closing cylinders consists of pneumatic cylinders for cushioning
coupled to hydraulic linear positioning cylinders. The linear positioners
preset the spike rolls for the diameter of the incoming log. The pneumatic
cushion cylinders allow the spike rolls to follow the contours of each log
and provide the holding power while the log is being turned.
Log Turning Cylinders: Heavy duty
long stroke hydraulic linear positioning cylinders are used to turn the
logs. Each linear positioner is complete with proportional valve,
Temposonics wand with cover, and a pressure filter assembly.
