As shown in FIG.

Further, gears 19A and 19B are attached to the tips of the support shafts 6 attached to the peeling rotary bodies 7A and 7B on the take-out portion 13 side. The gears 19A and 19B are connected via a chain 20 to gears 18A and 18B attached to the output shafts of the motors 17A and 17B.

In the figure, reference numeral 24 denotes a shooter provided below the skinning rotating bodies 7A and 7B, and 25 denotes a conveyor provided below the shooter 24. The bark 22 peeled off from the wood 21 is carried out of the apparatus. Is. Reference numeral 26 denotes a shooter provided in the take-out portion 13, and a wood carrying conveyor 27 is provided below the shooter. Reference numeral 28 denotes a motor provided on the take-out portion 13 side of the hopper 1, and 29 denotes a shutter that is driven up and down by the motor 28.

In the continuous wood peeling machine having the above configuration, when the motors 16A, 16B, 17A, and 17B are driven as shown in FIG. 3, the peeling rotary bodies 7A and 7B rotate in the direction of the arrow. The surface is peeled while the wood 21 is being scraped up by a plurality of stepped block-like skinning blades 10 arranged in parallel on the outer periphery of the skinning rotating bodies 7A and 7B. In this case, the peripheral speeds of the surfaces of the skinning rotary bodies 7A and 7B are kept the same.

At this time, as shown in FIG. 1, the peel-off rotating body 7B on the receiving side plate 2 side is formed to have an outer diameter larger than that of the peeling-off rotating body 7A on the sending side plate 3 side, and the height of the upper part of the peeling off rotating body 7B is increased. Since it is formed higher than the upper part of the peeling peeling body 7A, the wood 21 is smoothly fed from the sending side plate 3 to the receiving side plate 2 side by the peeling peeling body 7A. Further, the timber 21 is lifted by the receiving side plate 2 curved by the skin peeling rotating body 7B and efficiently rolls in the hopper 1. As a result, the surface bark 22 is efficiently peeled by the friction between the peeling blade 10 and the wood 21.

Further, the peeling blade 10 is formed so that the rising portion is sequentially raised in a stepped block shape, and a plurality of the peeling blades 10 are arranged in parallel on the outer peripheral surface of the peeling rotation bodies 7A and 7B, and are spirally trajectory spaced in the circumferential direction and the axial direction. Since it protrudes on top of the timber, it can be peeled in contact with the wood 21 efficiently. At this time, as shown in FIG. 6, the surface of the wood 21 is scraped by a wide area by the plurality of skinning blades 10 arranged side by side, so that compared to the conventional one or two skinning blades 10 arranged side by side. The scraping force is strong and efficiently rotated and peeled off.

Further, since the peeling rotors 7A and 7B are provided with the peeling blade 10 protruding on the outer peripheral surface of the pipe shaft 8 at intervals of 120 degrees in the longitudinal section of the pipe shaft 8, the exposed area of the surface of the pipe shaft 8 is exposed. However, the wood 21 is placed thereon and scraped up by the peeling blade 10, and even a bent material can be efficiently peeled off.

Further, since the center of the peeling blade 10 arranged in parallel on the outer circumferences of the peeling rotary bodies 7A and 7B is arranged on a spiral locus on the outer circumference of the pipe shaft 8, the picking section 8 is removed from the feeding section 7 while scraping up the wood 21. Can be smoothly fed by a feed screw action. For this reason, the wood 21 is automatically moved from the input unit 12 to the take-out unit 13 while being peeled without tilting the skinning rotating bodies 7A and 7B. At this time, the state of peeling of the wood 21 in the hopper 1 is visually confirmed, and the motor 28 is driven to lower the shutter 29 and adjust the height. The peeled wood 21 gets over the shutter 29, slides down from the shooter 26, and is carried out by the wood carry-out conveyor 27. Further, as shown in FIG. 1, the peeled bark 22 falls between the shooters 24 on both sides and is carried out to the outside by the conveyor 25.

In the present invention, the thickness of the stripping blades 10 arranged on the outer circumference of the stripping rotary bodies 7A and 7B is preferably 20 to 40 mm in terms of strength, and the number of the striping blades 10 is desirably 4 to 12, and the stripping of both ends is stripped. When the width of the blade 10 is in the range of 400 to 1000 mm, the wood 21 is brought into contact with a wide area, the scraping force is large, and the surface state of the wood 21 can be reduced. If the number of the skinning blades 10 is 3 or less and the width of the skinning blades 10 at both ends is less than 400 mm, the scraping force of the wood 21 is small, the surface brushing is large, and the number of the skinning blades 10 is 13 or more. When the width of the peeling blade 10 at both ends exceeds 1000 mm, there is a problem that the scraping force of the wood 21 is conversely reduced.

Moreover, in the said description, although the shape of the peeling blade 10 showed about the step shape, not only this but the thing of the optimal shape should just be selected with the material etc. of wood. Further, the skinning blade 10 is not limited to the one directly fixed to the outer peripheral surface of the pipe shaft 8 by welding, but may be one detachably joined. Further, in the above description, the case where two peel-off rotating bodies 7A and 7B are arranged side by side along the longitudinal direction is shown, but the present invention can be applied to the case where only one is provided.

FIG. 7 shows another embodiment of the present invention, in which two skin cutting blades 31 each having a cutting blade 30 formed on one side surface of a substantially trapezoidal block are juxtaposed on the surface of the pipe shaft 8. It is set. In recent years, bark is often used as biofuel or bark fertilizer, and with only the peeled off rotating bodies 7A and 7B, cedar and wood may be discharged for a long time without cutting the bark.

For this reason, as shown in FIG. 8, a plurality of skin cutting blades 31 are juxtaposed only on the side of the insertion portion 12 of the skinned rotating bodies 7A and 7B, whereby a plurality of skin cutting blades 31 are arranged on the surface of the bark 22 in a direction perpendicular to the longitudinal direction of the wood 21. The bark 22 peeled by scratching is cut short, and a raw material suitable as biofuel or bark fertilizer can be produced. In this case, a structure in which the peeling blade 10 on the input portion 12 side is replaced with a skin cutting blade 31 may be used.

In the above description, the case where the hopper 1 is installed horizontally on the stand 9 is shown, but it may be installed slightly inclined. Moreover, although the case where the upper part of the hopper 1 was opened over the full length was shown in the said description, you may attach a lid | cover to the part except the insertion part 12. FIG. In this case, the lid may be flat or round, and the lid may be detachable from or integrated with the hopper 1. In the above description, the peeling blade 10 protruding from the outer peripheral surface of the pipe shaft 8 is shown as being 120 degrees in the longitudinal section of the pipe shaft 8, but may be protruding at intervals of 90 degrees.
