DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a wood stripping apparatus suitable for stripping wood for building materials and for stripping wood in a process prior to the production of wood chips for papermaking.

[0002]

2. Description of the Related Art As this type of peeling machine, there has hitherto been, for example, one described in Japanese Patent Publication No. 2-17325. This conventional technique forms an opening along the longitudinal direction of the bottom of a hopper for storing and peeling wood, and a peeling rotating body having a number of peeling blades protruding from an outer peripheral surface of a pipe shaft. In a continuous peeling machine in which the upper part is inserted so as to close the opening, and the wood is rolled in the hopper and continuously fed in the longitudinal direction while peeling, the side plate constituting the hopper has an opening. In the lower end part which becomes a side edge, along the longitudinal direction, a comb-like groove through which many skinning blades pass is formed, and the lower part of the receiving side plate receiving the wood scraped by the skinning blade among the side plates is formed. It is characterized by being inclined inward and approaching the outer peripheral surface of the pipe shaft so that the lower end of the convex portion formed between the grooves is opposed to the base side of the peeling blade when viewed from the axial direction of the pipe shaft. With a continuous peeling machine That.

[0003]

In the above-mentioned prior art, a large number of pieces of wood put between the side plates are projected to the outer peripheral surface thereof by the rotational force of a pipe shaft arranged so as to close the lower opening of each side plate. The peeling blade can be peeled by the rotating force of the peeling blade while rotating while scratching the skin in the circumferential direction while picking up the receiving side plate and rotating in the direction of the sending side plate while repeating revolving.

[0004] However, in this conventional technique, during peeling of long fiber wood, the skin scraped out from the comb-like groove is
Because the fiber is long, the skin easily catches on both side chute plates of the conveyor for discharging the leather at the lower part of the pipe shaft, causing trouble in the processing of the peeling of the peeled skin of the wood. It is necessary to scrape the skin by hand, which is troublesome and workability is poor.In addition, many comb-shaped grooves must be formed at the bottom of the side plate receiving the wood, which is troublesome and troublesome. There were many problems that were said to be.

SUMMARY OF THE INVENTION An object of the present invention is to provide an inexpensive peeling apparatus capable of peeling a skin even when the fiber of the skin to be peeled is long, in order to eliminate the above-mentioned problems. And

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a machine frame provided with a hopper for storing wood, and an opening formed along a length direction of a lower portion of a pair of side plates constituting the hopper. In a wood peeling apparatus in which a number of peeling blades are protrudingly provided on an outer peripheral surface of a cylindrical body and a top portion thereof is horizontally laid so as to close the opening, the peeling blades of the respective side plates are scraped. This was achieved by forming the receiving side plate for receiving the lumber made of a substantially vertically arranged flat plate, and projecting a notch peeling blade that rises obliquely from the vicinity of the outer peripheral surface of the rotary cylinder body on the lower inner surface of the receiving side plate. The saw notch peeling blades may be connected and reinforced by a reinforcing rod.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, as shown in FIGS. 1 and 2, a basic mode of the present invention is to provide a machine frame 1 made of an iron material or the like with a hopper for storing wood W to be peeled. An opening 4 is formed below the pair of side plates 2 and 3 along the length direction.

A large number of peeling blades 5 having a mountain height on the lower side in the direction of rotation project from the outer peripheral surface of the cylindrical body in a number of rows.
A rotary cylinder 6 of about 0 to 70 cm is laterally provided by a rotary shaft 6A and a bearing 6B so that the lower half of the peripheral surface of the rotary cylinder 6 covers the opening 4.

Further, in the present invention, in particular, in each of the side plates 2, 3,
Among them, the receiving side plate 2 for receiving the wood W scraped by the rotating force of the peeling blade 5 is constituted by a flat plate fixed and disposed substantially vertically on the machine frame 1 and, for example, the receiving side plate between the rotation trajectories of the peeling blade 5. The rotary cylinder 6
1 and 3, a plurality of saw notch peeling blades 8 which rise up obliquely and obliquely from the vicinity of the outer peripheral surface toward the upper part of the receiving side plate 2 are bolted or welded firmly in a row to provide a wood peeling apparatus of the present invention. Construct the basic form.

The saw notch peeling blade 8 and the rotary cylinder 6
1 may be greater than or equal to the height of the peeling blade 5, as shown by the dashed line in FIG. 1. In this case, the saw notch peeling blade 8 can also be disposed on the rotation locus of the peeling blade 5. .

Further, a shooter S for guiding the peeling of the skin to the skin discharging conveyor B while preventing the peeled skin from scattering is disposed below the rotating cylinder 6, and the rotating shaft 6A of the rotating cylinder 6 is Transmission member G such as a chain or gear as shown in FIG.
To the rotation output shaft of the speed change motor M.

[0012] Of the side plates 2 and 3, a large number of peeling blades 5 are provided at the lower end of the side plate 3 on the side from which the wood W is sent out along its length in each circumferential line. A passing comb-shaped groove 7 is formed.

The wood peeling apparatus according to the present invention is configured as described above. When peeling the wood, first, the switch of the speed change motor M is turned on, and the state of the kind, shape, freezing, and drying of the inputted wood are firstly set. Thus, the number of rotations is determined and controlled, and a large number of pieces of wood W cut into a fixed length shorter than the length of the rotating cylinder 5 are exposed from the opening 4 between the pair of side plates 2 and 3 to a little less than half of the outer peripheral surface. It is put on the rotating rotary cylinder 6.

A large number of pieces of wood W entering between the side plates 2 and 3 are firstly moved upward in the direction of the arrow in FIG. With a narrow peeling blade 5 having the following shape, it is scooped up in the direction of the saw notch peeling blade 8 which rises obliquely while moving in the direction of the receiving side plate 2 while rotating while making a circumferential cut on the outer skin of each wood W. The skin can be finely cut by the saw notch peeling blade 8.

As described above, a large number of pieces of wood are rotated while being rotated, and a large number of pieces of wood are piled up and pressed by gravity, whereby the wood W moves in the axial direction, that is, in the discharge direction, and the next saw notch peeling blade. 8, the skin can be peeled widely while being further scooped and cut finely.

That is, a large number of woods W are modified so as to evenly hit a large number of narrow peeling blades 5 attached to the rotating cylinder 6 and a saw notch peeling blade 8 rising obliquely, and the above-mentioned press-down of a large number of woods is performed. It moves in the axial direction by action.

At this time, a large number of woods W on the rotary cylinder 6
Is lifted almost along the cylinder 6 while rotating, the outer skin is scratched by the narrow peeling blade 5, and other wood on the wood is similarly lifted while rotating, and a large number of wood Moves toward the saw notch peeling blade 8 which rises obliquely while rotating as shown by the arrow in FIG. 1, and scoops up the wood W by the narrow peeling blade 5, and at the time of this scooping, moves the wood W on its skin in the circumferential direction. In combination with the peeling action while making the cut, the wood W starts to be peeled off by the collision of the wood W.

The wood W moved as described above is
Further, the saw blade 8 can be peeled up while being cut up finely by the cutting edge with the saw notch peeling blade 8 rising diagonally, and flows down from the upper part of the receiving side plate 2 toward the feed side plate 3 as shown by the arrow in FIG. The above-described circulating movement involving the rotation and peeling of the whole wood W is repeatedly and smoothly performed.

Also, at this time, the outer skin of each wood W is cut in the circumferential direction by the rotating force of the narrow peeling blade 5 in a shape in which the lower side of the rotating cylinder 6 in the rotating direction gradually becomes higher. The peeling effect is large due to the cutting and peeling action of the saw notch peeling blade 8 which rises obliquely outward from the lower part of the inner surface of the receiving side plate 2, and the wood W is smoothly pressed by a large number of raw wood press-down actions by inputting a large number of wood W. It moves in the axial direction, and the peeled product can be discharged from the discharge port.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The saw notch peeling blades 8, 8 according to the present invention can be connected to each other by a reinforcing rod 9 shown by the shaving lines in FIG. 3 to increase the lateral strength of the saw notch peeling blades 8, 8. The short material or the branch can be received by the reinforcing rod 9 and peeled by the peeling blade 5. If both sides of the reinforcing rod 9 are fixed to the machine frame 1, the saw notch peeling blade 8 can be further reinforced.

[0021]

According to the present invention, a large number of woods W between the side plates 2 and 3
First, with the rotation of the rotary cylindrical body 6 in the direction of the receiving side plate 2 for scooping up the wood W, the outer skin of each wood W is cut in the circumferential direction by the narrow peeling blade 5 rotating in the rotating direction. The skin can be cut finely while being scooped up in the direction of the saw notch peeling blade 8 which rises obliquely while moving in the direction of the receiving side plate 2 while rotating.

As described above, a large number of pieces of wood are rotated and pressed by the gravity of the many pieces of piled-in wood, and the wood W moves in the axial direction, that is, the discharge direction, and the next saw notch peeling blade. Since the peeling blade 5 peels a wide area while cutting the skin finely while being further scooped up in step 8, there is a real advantage that troubles caused by the catching of the peeling can be solved when the peeling is discharged.

In particular, in the present invention, the peeling blade 5 is configured to pass through the lower portion of the receiving side plate 2 without any need for forming a comb-like groove in the lower portion of the receiving side plate 2. There is also a second effect that the receiving side plate 2 can be made with good workability, in combination with the fact that is a flat plate.

According to the second aspect, when a large number of skin cutting blades can be connected and reinforced by the reinforcing rods 9, the effect of being able to receive timber branches and short materials with the reinforcing rods 9 and peeling off with the peeling blades 5 is obtained. Could be added.
