In the state where the inclination angle of the log storage body 53 and the rotor 87 is horizontal (0 °), the raw log 7 is peeled off, for example, for 2 minutes.

Next, while the rotor 87 is rotated, the tilting hydraulic jacks 99 and 99 are operated, and the log storage body 53 is adjusted so that the inclination angle of the log storage body 53 and the rotor 87 becomes -1 ° in 30 seconds. 3 is lowered. At this time, the log 7 is moved to the right side in FIG.
Next, while the rotor 87 is rotated, the tilting hydraulic jacks 99 and 99 are operated, and the log storage body 53 and the rotor 87 are adjusted so that the inclination angle of the log storage body 53 and the rotor 87 becomes + 1 ° in one minute.

Next, the effect of the first embodiment will be described.
First, since the inclination angle along the axial direction of the rotor 87 (left-right direction in FIG. 3) can be changed, the raw wood 7 is moved in the axial direction of the rotor 87 (left-right direction in FIG. 3) during the skinning operation. As a result, the peeling plate 93 can be rubbed evenly against the raw wood 7 so that there is no residue and the skin can be peeled more uniformly.
Further, since the rotor 87 is tilted together with the log storage body 53, the configuration for tilting can be simplified.
The log storage body 53 is rotatably supported by the base 51 via the rear end side (left end side in FIG. 3), and the front end side is raised and lowered by tilting hydraulic jacks 99, 99. Therefore, the configuration for tilting can be simplified.

The ends can be aligned, and for example, the operation of aligning the ends when transporting the discharged log 7 is not required, and the work after peeling can be saved.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Although the batch type peeler 201 in the first embodiment is a single rotor type, the batch type peeler 201 according to the second embodiment is arranged in parallel as shown in FIG. This is a twin rotor type using a single rotor, that is, a first rotor 203 and a second rotor 205.

The first rotor 203 and the second rotor 205 have substantially the same configuration as the rotor 87 in the first embodiment, but the arrangement of the peeling plate 93 is the A type and the B as will be described below. There are two types of types.
First, in the case of the A type, the arrangement of the peeling plates 93 of the first rotor 203 and the second rotor 205 is the same, and the positions of the peeling plates 93 in the axial direction (perpendicular to the paper surface in FIG. 5) are aligned. .
In the case of the B type, the arrangement of the peeler plate 93 of the first rotor 203 is shifted in the axial direction (perpendicular to the paper surface in FIG. 5) compared to the second rotor 205, and The peeler plate 93 and the peeler plate 93 of the second rotor 205 are configured to alternate in the axial direction (perpendicular to the paper surface in FIG. 5).

Further, as shown in FIG. 5, a slit plate 207 is installed between the first rotor 203 and the second rotor 205, and a gap between the first rotor 203 and the second rotor 205. Thus, the log 7 is prevented from falling downward in FIG.
Further, as shown in FIGS. 6 and 7, on the first rotor 203 side (upper side in FIGS. 6 and 7) of the slit plate 207, the peeler plate 93 of the first rotor 203 passes. A slit 209 is formed, and on the second rotor 205 side (lower side in FIGS. 6 and 7) of the slit plate 207 is a second rotor slit 211 through which the peeling plate 93 of the second rotor 205 passes. Is formed.

  As described above, since there are two types of arrangement of the peeler plate 93 of the first rotor 203 and the second rotor 205, the A type and the B type, the first rotor slit 209 and the second rotor 209 of the slit plate 207 are provided. There are also two arrangements of the rotor slits 211. That is, in the case of the A type, as shown in FIG. 6, the positions of the first rotor slit 209 and the second rotor slit 211 in the axial direction (left-right direction in FIG. 6) are aligned. In the case of the B type, as shown in FIG. 7, the position of the first rotor slit 209 is shifted in the axial direction (left and right direction in FIG. 6) with respect to the second rotor slit 211. The slits 209 for the second and the slits 211 for the second rotor are configured to alternate in the axial direction (left-right direction in FIG. 6). The A-type slit plate 207 and the B-type slit plate 207 are selectively used depending on the arrangement of the peeling friction bodies 93 of the first rotor 203 and the second rotor 205.

Next, the operation of the second embodiment will be described.
The batch peeler 201 is also operated in the same manner as the batch peeler 1 according to the first embodiment.
In the case of the batch type peeling machine 201, since the two rotors, that is, the first rotor 203 and the second rotor 205 are installed, the peeling plate 93 is rubbed and peeled off at many places on the outer peripheral surface of the raw wood 7. The raw wood 7 is stripped more uniformly with no residue. In particular, when the arrangement of the peeler plates 93 of the first rotor 203 and the second rotor 205 is of the B type, the peeler plate 93 of the first rotor 203 and the peeler plate 93 of the second rotor 205 are axial (see FIG. 5 in a direction perpendicular to the middle of the paper surface), the stripping plate 93 rubs more portions of the outer peripheral surface of the raw wood 7, and the more uniform raw wood 7 is surely peeled without being left behind.

Next, the effect of the second embodiment will be described.
In the case of the second embodiment, the same effect as that of the first embodiment can be obtained.
In addition, since the two rotors, that is, the first rotor 203 and the second rotor 205 are installed, the stripping plate 93 rubs many places on the outer peripheral surface of the raw wood 7, and the above-mentioned raw wood is more uniform without being left behind. 7 can be peeled off. In particular, when the arrangement of the peeler plates 93 of the first rotor 203 and the second rotor 205 is of the B type, the peeler plate 93 of the first rotor 203 and the peeler plate 93 of the second rotor 205 are axial (see FIG. 5 in a direction perpendicular to the middle of the paper surface), the peeling plate 93 rubs on more portions of the outer peripheral surface of the raw wood 7, and there is no unremoved residue, so that the raw wood 7 can be peeled more uniformly. .

The present invention is not limited to the first and second embodiments.
For example, in the case of the first and second embodiments, the log storage body and the rotor are inclined by the same angle in the + direction and the − direction with respect to the horizontal, but the + direction and − The angle may be varied depending on the direction.
In the first and second embodiments, one cycle is constituted by horizontal, -α °, + α °, horizontal, and discharge.
