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]

According to the above-mentioned conventional technique, a large number of woods inserted between the side plates are projected onto the outer peripheral surface of the pipe shaft by the rotational force of the pipe shaft arranged so as to close the lower openings of the side plates. With the peeling blade provided, it can be peeled by the rotating force of the peeling blade while rotating while scratching the skin in the circumferential direction while scooping up toward the receiving side plate and rotating around the sending side plate.

[0004] However, in this conventional technique, during peeling of long fiber wood, the skin scraped out from the comb-like groove is
Since the fibers are long, the skin easily catches on both side chute plates of the conveyor for discharging the skin at the bottom of the pipe shaft, causing a problem in the process of discharging the peeled skin of the wood, and the pipe shaft is stopped for a long time each time. It was necessary to manually scrape off the skin, which was troublesome and poor in workability.

In order to eliminate the above-mentioned problems, the present invention provides an inexpensive peeling device capable of peeling finely cut leather even if the fiber to be peeled is a long wooden leather. With the goal.

[0006]

SUMMARY OF THE INVENTION An object of the present invention described above is to provide a machine frame with a hopper for accommodating lumber, and to form an opening along the lengthwise direction in the lower part of a pair of side plates constituting the hopper. Then, a rotary cylinder having a large number of peeling blades projecting from the outer peripheral surface of the cylinder is horizontally installed so that the upper portion thereof closes the opening, and the lower end of each side plate extends along its length direction. In constructing a wood peeling device having a comb tooth-shaped groove through which a large number of peeling blades pass, a receiving side plate for receiving the wood scraped by the peeling blade among the side plates is a substantially vertical plate. It is possible to achieve this by arranging the above-mentioned, and projecting the cutting blades that obliquely rise from the vicinity of the outer peripheral surface of the rotary cylinder on the inner surface of the lower portion of the receiving side plate between the grooves in the lower portion.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, as shown in FIGS. 1 and 2, the basic mode of the present invention is to provide a hopper for accommodating a wood W to be peeled on a machine frame 1 made of iron or the like. An opening 4 is formed in the lower portion of the pair of side plates 2 and 3 along the lengthwise 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 upper half of the rotary cylinder 6 closes the opening 4.

At the lower ends of the side plates 2 and 3, there are formed comb-teeth-shaped grooves 7 through which the large number of peeling blades 5 pass in rows in the circumferential direction along the length direction thereof. Configure a wood peeling device.

In particular, in the present invention, the side plates 2,
Among the three, the receiving side plate 2 for receiving the wood W scraped by the rotational force of the peeling blade 5 is constituted by a flat plate arranged substantially vertically in the machine frame 1, and the receiving side plate 2 between the grooves 7 at the lower part thereof. A plurality of rows of skin-cutting blades 8 rising obliquely in an arc shape from the vicinity of the outer peripheral surface of the rotary cylinder 6 toward the upper portion of the receiving side plate 2 are provided on the inner surface of the lower part of the wood of the present invention by welding. It constitutes the basic form of the peeling device.

Below the rotary cylinder 6, there is provided a shooter 9 for guiding the peeling of the peeled skin to the skin discharge conveyor 8 while preventing the peeled skin from scattering, and the rotary shaft 6A of the rotary cylinder 6 is As shown in Fig. 2, transmission members 1 such as chains and gears
It connects with the rotation output shaft of the transmission motor M via 0.

The wood peeling apparatus of the present invention is constructed as described above. When peeling wood, first, the speed change motor M is turned on to switch the tree species, shape, freezing and drying of the input wood. The number of rotations is determined and controlled depending on the state, and a large number of wood pieces W cut into a fixed length shorter than the length of the rotation cylinder 5
Is exposed from the opening 4 between the pair of side plates 2 and 3 and is placed on the rotating cylindrical body 6.

A large number of woods W that have entered between the side plates 2 and 3 are first of all gradually lowered in the direction of the arrow of FIG. With the narrow peeling blade 5 having the shape as described above, the outer skin of each wood W is rotated while making a circumferential cut, and is moved in the direction of the receiving side plate 2 while being scooped up in the direction of the skin cutting blade 8 which rises diagonally. The skin can be cut into small pieces.

As described above, a large number of pieces of wood are rotated and stacked, and a large number of pieces of wood put in and piled up cause the pressing force of the pieces of wood due to gravity to move the piece of wood W in the axial direction, that is, in the discharging direction, and the next skin cutting blade. It can be peeled widely by cutting the skin finely while being scooped up further in 8.

That is, a large number of wood pieces W are modified so as to evenly hit a large number of narrow peeling blades 5 attached to the rotary cylinder 6 and a skin cutting blade 8 which rises diagonally. It moves in the axial direction by the action.

At this time, a large number of wood W on the rotary cylinder 6
The outer skin is damaged by the stripping blade 5 having a narrow width when it is lifted almost along the cylinder 6 while rotating, and other woods on the wood are also rotated while being lifted, and a large number of whole woods are also lifted. 1 moves toward the skin cutting blade 8 which rises diagonally while rotating as shown by the arrow in FIG.
When the scooping up of the wood W is caused by the scrubbing of the wood W, the epidermis of the wood W is scratched in the circumferential direction at the time of scooping up, and the scraping action of the woods causes a frictional peeling of the wood W.

Then, the wood W moved as described above is
Further, the bark can be peeled off while finely cutting the bark while being scooped up by the skin-cutting blade 8 which rises diagonally. As shown by the arrow in FIG.
The woods W and W circulate downward so as to roll down, and the rotation of the whole wood W, and the above-described circulation movement accompanied by a peeling action are repeatedly and smoothly performed.

Also, at this time, the outer skin of each wood W is cut in the circumferential direction due to the rotational force of the stripping blade 5 having a shape in which the lower side of the rotary cylinder 6 in the rotational direction gradually becomes higher. The peeling effect is large due to the skin-cutting and peeling action of the skin-cutting blade 8 that rises diagonally outward from the lower portion of the inner surface of the receiving side plate 2, and the wood W is smoothly pushed by the pushing-down action of a large number of raw wood by the introduction of a large number of wood W. The peeled product can be discharged from the discharge port by moving in the axial direction.

[0019]

[Effect of the Invention] A large number of woods W that have entered between the side plates 2 and 3 are
First, with the rotation of the rotary cylinder 6 in the direction of picking up the wood W, the peeling blades 5 having a narrow width in the rotation direction rotate the outer skin of each wood W while making circumferential cuts on the outer skin of the wood W to rotate the receiving side plate 2. The skin can be finely cut while being scooped up in the direction of the skin cutting blade 8 which rises diagonally while moving in the direction.

As described above, a large number of pieces of wood are rotated and stacked, so that the large number of pieces of wood are pushed by the force of gravity to move the pieces of wood W in the axial direction, that is, in the discharge direction. Since the skin can be peeled widely by cutting the skin finely while being further scooped in 8, there is a real benefit that the trouble due to the skin being caught can be eliminated when the peeling is discharged.
