Description

The present invention relates to a peeling machine for peeling wood for chips or building wood.

(B) Conventional technology Conventionally, a peeling machine in which two peeling rotating bodies are mounted in parallel in one opening provided in a lower part of a wood container is disclosed in Japanese Utility Model Laid-Open No. 62-2736.
It is already known from the 9th publication.

Since the known peeling machine was a method of directly passing wood from the peeling rotary body on one side to the peeling rotary body on the other side, the wood peeled by the peeling rotary body on one side is extremely small in resistance, that is, It is supported by the peeling rotator and is easily transferred to the peeling rotator on the other side while being received by the peeling blade protruding from its outer peripheral surface. As a result, the wood circulates, but the relatively small diameter wood Or the peeling efficiency for light wood was low.

Therefore, in order to solve the problems of the peeling machine, a peeling machine in which a resistor is provided between the peeling rotating bodies has been proposed.

(C) Problems to be Solved by the Invention The improved peeling machine could improve the peeling efficiency by the peeling rotating body on one side, but the wood had a bend, a knot or a bump, so it was protruded. Because the part contacts the resistor,
The peeling effect of pressing the wood against the resistor was extremely small.

(D) Means for Solving the Problems The present invention provides an elongated receiving member substantially parallel to the wood processing frame at the bottom between both side walls of the wood processing frame having one end serving as a discharge port. An opening is formed between the side plate and the opening, and the upper portions of a plurality of peeling rotary members having a large number of skinning blades are respectively inserted into the openings to be pivotally supported, and the length of the peeling rotary member is set on the receiving member. A large number of peeling members in a direction intersecting with the vertical direction are protruded at intervals in the length direction, and the upper surface of the peeling member is inclined such that the lower side in the rolling direction of the wood is sequentially increased, and the wood is rotated in one of the peeling directions. When the wood is transferred from the body to the other peeling rotating body, the wood is received on a narrow surface separated by a peeling member on the receiving member, and the peeling action is also performed by the peeling member itself. Solved the problem.

(E) Action When wood with bark is put into one end of the wood processing frame,
The peeling blade of the peeling rotator peels the wood while rolling it from one side to the other in the width direction of the wood processing frame, and when the wood is transferred to the other peeling rotator, the peeling member is the length of the wood. At a position spaced apart in the direction, the wood is received on a narrow slope, and in this state, the wood is peeled by the pressing action and the rolling action received from the peeling blade of one of the peeling rotary members.

The wood transferred from the peeling member to the other peeling rotary body is further peeled by the peeling rotary body, and the wood reaching the side wall is pushed up by a peeling blade protruding from the outer peripheral surface of the peeling rotary body. Is further pushed up and rolled by the wood, which rolls back and circulates on the wood which has been peeled.

(F) Embodiment One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a side plate 2 or 3 having an open upper portion and an inclined or curved lower portion; And a discharge section 6 having a shutter which can be opened and closed on the side, and has a rectangular shape in plan view, is fixed to the machine frame, and has an intermediate bottom portion between both side plates 2 and 3. Has a wood processing frame 1
And an elongated receiving member 7 parallel to the longitudinal direction of the receiving member 7 is provided.
Are formed in two openings 8, 9 parallel to the length direction of the wood processing frame 1 between the both sides of the side plate 2 and the lower end of the side plates 2, 3, and a plurality of steps are formed on the outer peripheral surface that is inclined upward. A number of peeling blades 10 having projections are provided on the outer peripheral surfaces of the cylindrical peeling rotators 11 and 12 at appropriate intervals in the circumferential direction and the length direction, and these peeling rotators 11 and 12 are removed. The machine frame is inserted into the openings 8 and 9 respectively.
13 is rotatably supported by bearings 15.

Further, comb-shaped slits 16 through which the skinning blades 10 pass are provided on the lower edges of the side plates 2 and 3 and both side edges of the receiving member 7, respectively. The rotation trajectory of the peeling blade 10 protruding from the horizontal direction is separated from the peeling rotating bodies 11 and 12 in the horizontal direction when viewed from the longitudinal direction, but the inner end thereof overlaps the receiving member 7 in the vertical direction.

On the upper surface of the receiving member 7, a peeling member 14 formed of a triangular plate as viewed from the length direction of the peeling rotary body 11 is attached, and the peeling member 14 is formed by welding a seat plate 19 to the bottom surface. This is screwed to the receiving member 7 in a replaceable manner with bolts, and the upper side in the rolling direction of the wood is divided as shown in FIG. 4, and the ridge 14a and the groove 14b in which it is fitted are formed on the divided surface. The blade portion 14c is screwed to the base portion 14e with a bolt 14d, and a plate 14f welded to the slope of the base portion 14e receives the blade 14c, and the blade portion 14c is shown by a solid line in FIG. As shown by the dashed line (indicating the top of the projection), the inclination angle is different, or the projection is replaced with a different inclination angle, or it is replaced when worn out, in which case the large diameter tree or bark is easily peeled off The angle of inclination should be small for wood, and for small diameter trees or those where the bark is difficult to peel off, the slope should be steep and the bark should be thick. When is the large pitch and height of the protrusions.

Further, the receiving member 7 is supported by screwing both ends thereof to the machine frame 13 so as to be fixed or detachable, and the intermediate part is fixedly or detachably screwed to one or a plurality of columns 17 at intervals. However, when viewed from the axial direction of the peeling rotary body 11, the lower side in the wood lateral movement direction is slightly lower, or horizontal, or slightly higher although not shown.

In the above-described peeling machine, the peeling rotary bodies 11 and 12 are driven to rotate sprockets 20 and 21 attached to their end shafts in the same direction by a motor 22 through a chain 23, whereby the peeling blades 10 When the timber that has entered the wood processing frame 1 through the slit 16 at the lower edge of the swash plate 25 protruding from the side plate 2 is pushed up and turned sequentially to peel, and reaches the receiving member 7, the timber is stripped. After pushing up toward 14, it retreats through the slit 16 of the receiving member 7, and the peeling member 14 receives the wood by the narrow slopes of the many peeling members 14 spaced apart in the length direction to suppress lateral movement. I do. At that time, bent or knots or bumps in the wood are likely to enter between the peeling members 14, and the peripheral surface of the wood is separated from the peeling members in the length direction.
It is pressed against 14 narrow slopes with concentrated load.
The bark that has been floated due to being woken up by the wood or colliding with each other during circulation is pushed off and discharged from between the slits. During the peeling, the plurality of projections provided on the slope of the peeling member 14 bite into the bark and cause the bark, and the wood whose lateral movement is suppressed is subsequently peeled by the peeling rotating body 11 on one side. Since the wood is received, the peeling performance of the peeling rotary body 11 by the peeling blades 10 can be enhanced, and the wood that has been placed on the peeling member 14 and has moved out of the rotation trajectory of the peeling blade 10 is pushed by the subsequent wood. Rolling
At that time, the projections of the peeling member 14 make cuts in the bark of the wood, and when the bark is hard and brittle like hardwood, and when the bark is a thick bark, it collides during the rolling of the wood. Since the peeling starts from the cut, the peeling action can be promoted.

Next, when the wood exceeds the top of the peeling member 14, it falls on one side of the peeling rotating body 12 on the other side, moves while rolling on the other side while being peeled by the peeling blade 10, and moves to the side plate 3. When it arrives, it is pushed up while being pressed against the lower slope, and at this time, at an appropriate interval in the length direction of the wood processing frame 1 or a portion corresponding to the slit 16. In the case, the upper part of the slit 16 on the better side) a large number of strip-shaped resistors 29 are welded, and a plurality of projections are provided on the upper surface thereof, so that the same peeling treatment as the peeling member 14 is performed, The pushed up timber falls down to one side of the peeling rotating body 11 side and is further peeled.

By repeatedly performing such peeling, the wood processing frame 1
And since the peeling rotating bodies 11 and 12 are higher in the input section side and lower in the discharge section side, the wood is sequentially shifted to the discharge section side, and the peeled wood is sequentially discharged from the discharge section.

5 to 8 show another embodiment, in which reference numeral 30 denotes a resistance plate extending over substantially the entire length of the peeling rotating bodies 11 and 12, which are inclined substantially in the same manner as the upper surface of the peeling member 14. 7 is fixed to the seat plate 19 by a connecting plate 31. The seat plate 19 is screwed to the receiving member 7 with bolts 19a. The above-described resistor 29 is mounted on the upper surface of the resistor plate 30 in FIGS. When fixed so as to correspond to the gaps between the slits 16 as shown in FIG. In this embodiment, the protrusions provided on the upper surface of the resistor plate 30 are formed by the resistor 29. However, a large number of independent protrusions may be provided on the upper surface of the resistor plate 30 at intervals vertically and horizontally. In addition, the upper part of the resistance plate 30 or the left slope of the connecting plate 31 in FIG. 5 receives the wood that has fallen on the peeling rotating body 12 on the other side.

(G) Effect of the Invention Since the present invention is configured as described above, the wood peeled by the peeling rotating bodies 11 and 12 on one side is received by the peeling member 14 and the movement thereof is suppressed. The peeling efficiency of the peeling blade 10 of the rotating body 11 on the side can be improved, and the peeling members 14 can be formed by projecting protrusions, knots or bumps at parts spaced apart in the length direction of the wood. The bark received by the concentrated load is peeled off while avoiding the like, and the floating bark is peeled off. When the wood is transferred to the peeling rotating body 12 on the other side, good peeling can be performed with little residual bark.

In the case where a protrusion is attached to the upwardly inclined surface of the peeling member 14,
Peeling treatment can also be performed by the projections, and the peeling performance can be further improved.

In the case where the upper portion of the peeling member 14 or the resistance plate 30 is made detachable, when they are worn, or when the resistance value is a tree species or a frozen material, or in accordance with the felling time, the resistance value can be replaced. it can.
