This equipment comprises a cylinder 3 around its central axis 2 rotations, and pending round log 1 is admitted to by the space that the cylinder-shaped inner sleeve 4 by this cylinder limits, and thus, round log is dawdled and impacted, to handle bark.Cylinder 3 is supported in a position that tilts by this way, so that central axis 2 is with respect to horizontal plane α in an acute angle.The size of angle [alpha] is in 2 °～12 ° scope.Value commonly used is about 5 °.
In the example shown in the figure, cylinder 3 is supported on the wheel 12 from the outside, and is provided with the device of reference number 13 representatives of applying greatly, to be used for swing roller 3.
For the sake of clarity, round log 1 is fed to the conveyer in the cylinder 3 and will further be delivered to from the round log 1 that the discharge end of cylinder 3 is discharged below the processing stage conveyer, all from accompanying drawing, omit.
Form an inner member 5 in cylinder 3, it can fix or be adjusted to desired position.Member 5 is arranged to extend to the desired zone of cylinder 3, in other words, along the whole length of cylinder or just extend, and be arranged to the space segmentation that the cylinder-shaped inner sleeve 4 by cylinder 3 limits along the part of its length be special-purpose processing space 6 and be retained in space 7 outside it.So, through the round log 1 of cylinder 3 feedings just via above-mentioned processing space 6 cylinder 3 of passing by.Like this, handle space 6 and comprise that one is positioned at the passage at both ends open of cylinder 3, the inner sleeve surface of this passage is formed by the wall 17 of entity on the one hand, the part of inner sleeve 4 at above-mentioned wall place by the rotation of cylinder 3 forms on the other hand, and this wall 17 is formed by the inner member 5 that is adjusted to desired position.
Relative motion between the inner sleeve 4 of round log 1 and cylinder 3 can change by the position that changes inner member 5.
As being clear that in Fig. 1 and 3, inner member 5 is arranged to central axis 2 rotations around cylinder 3.Inner member 5 can not be mounted to yet and rotate with respect to cylinder.In order to rotate, inner member 5 supports with the spring bearing on suitable beam 14 and the framework at equipment 16 at two ends.As being clear that among Fig. 3, inner member 5 usefulness one actuator 15 is locked on its normal position that is formed by its actual operational position.The end that pulls spring that for example may comprise of actuator 15 is fixed on the framework 14 of entity, and the other end then is fixed on the inner member 5.
In one embodiment, inner member 5 is arranged to when having a masterpiece that surpasses predetermined force to be used on the inner member 5, from its operating position or normal position turn-off, and, correspondingly, when the above-mentioned power that surpasses predetermined force fails, be back to its normal position.If in the slit 9 of the bark wedge of timber between the inner member 5 of cylinder 3 that rotates in the direction of arrow B and inner sleeve 4, this power will produce, this means, because the damage that causes that chokes suddenly of cylinder 3 and inner member 5 can reduce or avoid fully.
