Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, a peeling device is already known that peels a log by moving a peeling rotating body having a large number of peeling blades in pressure contact with the circumferential surface of a log and moving the log relatively in the longitudinal direction and the circumferential direction. ing.

However, when peeling the bark of cedar or cypress trees, which have long fibers and are strong, the peeled bark wraps around the peeling rotor, making it impossible to peel the bark. had to be removed by hand, which reduced work efficiency and was extremely dangerous.

The present invention improves the above-mentioned drawbacks, is easy to manufacture, can reliably hold the bark cutting piece for cutting the rolling bark on the peeling rotary body, and can quickly replace the bark cutting piece. The object of the present invention is to provide a wood peeling device capable of debarking, in which a debarking rotary body having a number of protruding debarking blades spaced apart in the circumferential direction is pressed against the outer periphery of a log, and the debarking rotary body is A bark cutting device for peeling a log while relatively moving it in the length direction and circumferential direction, wherein a bark cutting piece for shredding the bark is removably attached to the side surface of the bark peeling rotary body, and in the circumferential direction. A peeling device that presses a peeling rotor having a number of protruding peeling blades at intervals on the outer periphery of a log, and peels the log while moving the peeling rotor relatively in the lengthwise direction and the circumferential direction of the log. , No. 111 The bark-peeling rotary body is characterized in that an uneven portion is provided on the side surface, and a skin cutting piece for shredding the bark is engaged with the uneven portion and can be detachably removed.

To explain the embodiment shown in the drawings below, I is a ring that is guided by a gate-shaped machine frame 1a, lowers R together with a holding frame 1b, rotates around a log inserted into a center hole, and has a peeling rotor at its tip. A plurality of swinging arms 4.phi., each of which supports the body 2 by a support shaft 5, are installed in a fixed manner, and each peeling rotary body 2...
is forcibly driven, and a transfer device consisting of a chain conveyor 6 and rollers 7, which move up and down in opposite directions in a phase 11', is provided in front and behind the ring 1, similar to the conventional one.

As shown in FIGS. 3 and 4, the peeling rotary body 2 is constructed by protruding from the outer periphery of a rotary body 2a a large number of peeling blades 2b consisting of protrusions at regular intervals in the circumferential direction. There is,
The lead angle of this peeling blade 2b is appropriately selected between 0 and 45 degrees, and in this embodiment, it is 45 degrees.

- Also, a skinning blade 2 is provided on the feed side side of the skinning rotary body 2.
A skin-cutting piece 8 shown in FIG. The recess 9a...
and insert the bolt into the hole 8a to remove the peeling rotary body 2.
The skin-cutting pieces 8 are fixed to the skin-peeling rotary body 2 by screwing into the hole 2c of the skin-cutting piece 8, and a locking piece 8b is protruded from the end of the skin-cutting piece 8.

8b engages with the outer circumferential surface and inner circumferential surface of the protruding strip 9 to prevent the bark cutting piece 8 from rotating due to bark cutting resistance.

Furthermore, as shown in FIG. 3, the outer end of the skin cutting piece 8 is slightly lower than the skin peeling blade 2b in front view, and in side view, as shown in FIG. Cut the bark connected by this protrusion.

Further, a donut-shaped disk 10 whose outer peripheral surface is lower than the skinning blade 2b by, for example, 2 to 10n++n (2 to 3mm in the illustrated example) is fixed to the outer peripheral side of the delivery side side of the peeling rotary body 2 by screws 11. ing.

In the apparatus described in if1, when the log is fed into the center hole of the ring l by the transfer device and the swinging arm 4 is swung by the air cylinder to press the peeling rotary body 2 against the outer peripheral surface of the log, the log moves at a constant speed. The peeling rotor 2.
- performs skinning by revolving around the log together with ring l while rotating.

At this time, since the fibers of the bark of cedar and cypress are strong, the peeled bark tries to wrap around the log and the peeling rotary body 2, but the bark cutting piece 8 cuts it short.

During this bark cutting, the bark cutting pieces 8 are screwed while engaging with the irregularities on the side surface of the bark peeling rotary body 2, so even if a dog cutting resistance is applied to the bark cutting pieces 8... The protruding piece 8 is firmly held without rotating and can reliably cut the bark.

Incidentally, since the periphery 11 of the peeling protrusion 8 is due to the engagement between the skin cutting protrusion 8 and the unevenness on the side surface of the peeling rotary body 2, it is of course possible to replace it with other equivalent means. .

In addition, when the cut part (corner) of the skin cutting piece 8 becomes worn, if the skin cutting piece 8 is rotated 180 degrees and attached, the unused other end can be used, and a new skin cutting piece can be used. It is also easy to replace it with piece 8.

Next, another embodiment of the present invention will be described with reference to FIG. It is the same as the embodiment described above, and is pivoted on the lower ends of a pair of left and right swinging arms suspended from the gate frame, and is forcibly driven to rotate by an appropriate transmission mechanism, and is pressed against the circumferential surface of the log. and
The log is held by a wood gripper 20 and moved in its length direction while being rotated, or the log is rotated at a fixed position and a gate frame is run in the length direction of the log to debark it.

In this embodiment as well, the bark cutting piece 8 cuts the wrapped bark into short pieces.

Since the present invention is configured as described above, the fibers of cedar and cypress bark are extremely strong and can be wrapped around a log or a peeling rotary body, but it can be cut into short lengths with the bark cutting piece, which is dangerous. There is no need to remove the skin, which is huge and takes a long time.
Skin can be peeled with high efficiency and extremely easily.

Further, since the skin cutting piece can be sharpened on the side surface of the skin peeling rotary body, it can be manufactured and attached separately from the skin peeling rotary body,
The cost can be reduced compared to one that is integrally formed with the peeling rotary body, and when the skin cutting piece is worn out, it can be peeled off by attaching and removing only the skin cutting piece separately from the skin peeling blade, making it unstable. It is possible to accurately and efficiently peel off the bark of a tree with a sharp bark cutter.

Furthermore, when cutting the bark, an extremely large cutting resistance is applied to the bark cutting pieces, but since the bark cutting pieces are engaged with the irregularities on the side surface of the bark peeling rotary body, the bark can be removed easily. The protrusion does not shift due to cutting resistance, and the bark can be cut reliably for a long period of time while being firmly held.
