CONSTITUTION:When lumbers are supplied to a supply part by a supplying conveyor or the like, barking blades 6 act to push up and transfer the lumbers while rotating them, and the lumbers are barked by being circulated, and as the barking process is continued, the lumbers are moved one by one to the side of an exclusion part 1c, and when one end of the lumber is transferred on a cover 17 between front and rear rotating bodies 5, 5, the transfer plates 18 push up intermittently in a few times the side of top part of the lumber while the rotating body turns once. By the reason, the tip part of the lumber is transferred with ease on the rotating body 5 at the lower side, and transfer plates 18 at the initiation side of the rotating body 5 also repeat pushing up in the same manner of the transfer plate 18 at the termination end of the upper side rotating body 5. They are transferred on the cover 17 not being stopped almost, and when the termination end of the lumber rides on the cover 17, the half length or more of the lumber is being ridden on the rotating body 5 at a lower side, thus they are transferred smoothly.

Description

[Detailed description of the invention] (b) Industrial application fields The present invention relates to a pulpwood debarking machine.

(B) Prior art Conventionally, a wood processing container with a wood supply section at the upper end of one end and a discharge section at the other end is mounted on a machine base so that the discharge section side is lower than the supply section side, and a plurality of cylindrical rotating The rotary bodies are connected in series with bearings at both ends, and a part of the outer circumferential surface of these rotary bodies is fitted into the lower opening of the wood processing container, and a large number of peeling blades are protruded on the outer circumferential surface of the rotary body. The peeling blade passes through a comb-shaped slit provided on the side edge of the opening, and the wood supplied to the wood supply section is sequentially peeled by the peeling blade while moving toward the discharge port. The bearing portions of the rotating bodies that are adjacent to each other at the front and rear are covered with covers that extend along the circumferential surface of the rotating bodies, a disc is fixed to the shaft for bearing the rotating bodies, and a skin is peeled off on the outer periphery of the disc. We have already proposed a peeling machine in which a protrusion similar to a blade is provided to facilitate the movement of wood from the upper rotating body to the lower rotating body.

(c) Problems to be Solved by the Invention The disk for making the wood go over the cover of the bearing in the known peeling machine has a large diameter, which increases the cost and also increases the cost. There were problems such as bark, wood chips, etc. getting stuck in the gap with the cover and the gap between the disc and the rotating body, and the disc deforming due to the heavy wood.

(d) Means for Solving Problems The present invention provides a wood processing container with a wood supply section at the upper end of one end and a discharge section at the other end, mounted on a machine base such that the discharge section side is lower than the supply section side. A plurality of cylindrical rotating bodies are mounted in series with bearings at both ends, and a part of the outer peripheral surface of the rotating bodies is fitted into the lower opening of the wood processing container. A large number of peeling blades are provided protruding from the outer peripheral surface so that the peeling blades pass through comb-shaped slits provided on the side edges of the opening, and the wood supplied to the wood supply section is directed toward the discharge port. In the peeling machine that sequentially peels the skin with the peeling blade while moving, a plurality of transfer plates passing through the same slit are arranged in the circumferential direction on the outer circumferential surface of the side end of the continuous part of the rotating bodies arranged in series. When the wood is transferred from the upper rotating body to the lower rotating body by protruding integrally at intervals, the slits are integrally protruded at intervals in the circumferential direction at a portion corresponding to one slit. The above-mentioned problem was solved by pushing up the wood using a plurality of peeling blades and allowing it to pass over the cover between the front and rear rotating bodies.

(E) When the wood is put into the wood processing container from the action supply section, the wood is sequentially stripped by a large number of stripping blades protruding from the outer circumferential surface of the rotating body and moves toward the discharge section. When moving from the rotary body to the rotary body on the lower side, a plurality of transfer plates protruding at intervals on the same circumference sequentially move the wood multiple times at the same phase position as the rotary body rotates. As the wood is pushed up, it smoothly passes over the two bearings or the cover that covers the two bearings and the transmission wheel, and moves to the starting end of the rotating body on the lower side.When the tip of the wood moves to the rotating body on the lower side, Since the peeling blade at the starting end of the rotor joins the tip of the wood, it performs the same pushing up action as described above, and even when the terminal end of the wood rests on the cover, it performs the pushing up action as described above, so that the transition is smooth.

(F) Example Below, to explain the example shown in the drawings, l is a wood processing container horizontally mounted on the machine base 2 so that the delivery side is lower, and the starting end side of the wood processing container l is on the upper side. The upper part is opened to serve as a supply part, and a flow plate 4 extending laterally is attached to the side part of the supply part. It is composed of an end plate and has an opening 3 at the bottom.
In this embodiment, the delivery side is cylindrical, but the upper part may be open.

In addition, a plurality of drum-shaped rotating bodies 5 are arranged in series at the bottom of the opening 3 of the wood processing container l, and are arranged at an angle so that the delivery side is lower than the supply side. A part of the outer circumferential surface of the rotary body 5 is fitted into the opening 3, and a large number of peeling blades 6, which are gradually higher on the lower side in the rotational direction and have a plurality of irregularities on the inclined surface, are spirally attached to the outer circumferential surface. It is arranged and welded.

Further, a discharge part 1c is provided at the transfer end of the wood processing container l, and a chino 1 is connected to the discharge part 1c by a motor 8.
A shutter 11 is provided which is driven up and down through the shutter.

Furthermore, a number of comb-like slits 12 are carved in the lower edges of the side walls 1a and 1b of the wood processing container l, and each of the peeling blades 6 is connected to the wood processing container. When going in and out of L, it passes through the slits 12.

Furthermore, on the inner peripheral surface of the end of the rotary body 5.5, which is connected in series around 1, a shaft 15 is connected via a plurality of rectangular plates 13 arranged radially when viewed from the axial direction. The shafts 15 are fixedly supported on the machine base 2 via bearings 16, and the upper part of these bearings 16 is covered with an arc-shaped cover 17 that coincides with the outer peripheral surface of the rotating body 5. covered by.

And, on the outer circumferential surface near the cover 17 of the rotating body 5,
A plurality of transfer plates 18... passing through one slit 12 (on the same circumference) are welded in rows spaced apart in the circumferential direction, and these transfer plates 18... rows are adjacent to each other. The slits 12 may be provided in correspondence with each other, or may be provided every other slit as shown in the figure, and the range is from 1/4 to 1/4 of the length of the wood to be stripped from the end of the rotating body 5. The length is about 1/2, and the other parts are provided with peeling blades 6 as described above.

In the above-mentioned peeling machine, when the rotating body 5 is driven to rotate via a speed reducer by a motor provided on the supply side and discharge side of the wood processing container 1, and the wood is supplied to the supply section by a supply conveyor or the like, The peeling blade 6... moves the wood while pushing it up, circulates it, and peels the wood, and when this kind of peeling process continues for m, the wood sequentially moves to the discharge part lc side, and one end of the wood rotates back and forth. Cover 1 between body 5.5
7, the transfer plate 18 in the same row intermittently pushes up the tip of the wood several times during one rotation of the rotating body, so the tip of the wood can easily rotate downward. The transfer plate 18 on the starting end side of the rotating body 5 repeats the same pushing up as the transfer plate 118 on the terminal end of the rotating body 5 on the upper side, so it moves over the cover 17 without stagnating. When the wood moves and the end of the wood rests on the cover 17, half or more of the length of the wood rests on the rotating body 5 on the lower side, so it moves smoothly.

At this time, the transfer plate 18 is constituted by a plate having a smooth surface that is successively higher on the lower side in the rotation direction, so the skinning blade 6 has a plurality of protrusions on the slope that is successively higher on the lower side.
As shown in the figure, the protrusions do not pierce the bark or woody parts of the tree, allowing smooth movement of the wood.

However, the peeling blade 6 may be a movable plate, and in this case,
The peeling blade 6 facilitates the movement of wood from the upper rotating body 5 to the lower rotating body 5, but the conveying performance is better when the slope does not have any protrusions.

In addition, the number of transferred mlB in one row is the diameter of the rotating body, or
It increases or decreases within the range of 2 to IO in proportion to the weight of the wood, etc.
A large number of protrusions 1 are provided on the outer periphery between the transfer plates 18 that are adjacent to each other in the circumferential direction.
By fixing the peeling body 20 having 9..., the peeling performance can be improved.

FIG. 3 shows another embodiment of the present invention. When two rotating bodies 5 are arranged in series as in the previous embodiment, they are driven at the starting end and the terminal end of the wood processing container 1. I can, but 3
If more than one rotary body is installed in series, the pulley 21 or sprocket that drives the intermediate rotary body 5 must be attached to the shaft 15 between the front and rear rotary bodies 5, so the cover 1
7 becomes longer and the movement of the wood becomes unsmooth, but even in such a case, smooth transfer can be achieved by attaching transfer plates 18 to the outer periphery of the front and rear rotating bodies 5 in the same way as in the previous embodiment. 6 The present invention also includes two rows of rotating bodies 5... provided in parallel at the lower part of the wood processing container 1 or from the lower part to the side, in which case, the left and right rotating bodies 5. It is desirable to interpose a transition plate having comb-like slits on both sides between the two sides. Furthermore, the transfer plate 18 is also provided at the rear end of the rearmost rotating body 5.
By protruding a plurality of slits corresponding to the slits 12, the peeled wood can be easily discharged.

(G) Effects of the Invention As described above, the present invention provides a wood processing container l having a wood supply section at the upper end of one end and a discharge section at the other end, mounted on the machine base 2 such that the discharge section side is lower than the supply section side. A plurality of cylindrical rotating bodies 5 are mounted in series with bearings at both ends, and a part of the outer peripheral surface of the rotating bodies 5 is connected to the wood processing container l.
A large number of skinning blades 6 are protruded from the outer peripheral surface of the rotating body 5, and the skinning blades 6 pass through a comb-shaped slit 12 provided at the side edge of the opening 3. Do as you like,
In a peeling machine that sequentially peels the wood supplied to the wood supply section by the peeling blade 6 while moving the wood toward the discharge port, Since a plurality of transfer plates 18 passing through the same slit 12 are integrally provided on the surface at intervals in the circumferential direction, the wood supplied from the supply section into the wood processing container l is
