Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention involves fitting the upper part of the rotating body into the lower opening of the wood storage body, and peeling the wood using a large number of peeling teeth protruding from the circumferential surface of the rotating body. Regarding wood peeling machines.

(B) Prior Art Conventionally, the upper part of a rotary body is fitted into the lower opening of a wood storage body, and a comb-shaped slit is provided in the lower part of the side wall of the wood storage body, through which the skinning blade on the outer periphery of the rotary body passes. A peeling machine is already known from Swedish Patent No. 181464.

(c) Problems to be Solved by the Invention When the bark is peeled using the known peeling machine, wood pieces such as backboards generated inside the wood storage body are separated between the slits on the lower edge of the wood storage body and the outer peripheral surface of the rotating body. This caused the debris to become jammed and clogged, putting an overload on the rotating body and significantly reducing debris discharge performance.

(d) Means for Solving the Problems The present invention provides a method of horizontally suspending a wood storage body 1 with an open upper part, opening the lower part of the wood storage body 1 over almost the entire length, and installing a drum horizontally suspended below the wood storage body 1. A part of the rotary body 5 having a shape is inserted into the wood storage body 1 through the opening, and a large number of peeling teeth 6 are formed on the outer peripheral surface of the rotary body 5.
..., and a circumferential strip is attached to the outer peripheral surface of the rotating body 5, and the lower part of the side wall of the wood storage body 1 is brought into sliding contact with the strip, or the strip is attached to the lower edge of the side wall and the rotating body. By fitting it into the notch provided in the lower edge of the side wall at a height higher than the gap with the circumferential surface of No. 5, it rests on the circumferential surface of the rotating body and the peeling teeth face the lower edge of the side plate on the side that exits from the wood storage body. The above-mentioned problem can be solved by moving the piece of wood while supporting it with a strip, and when it reaches the bottom of the side panel, the part of the piece of wood supported by the strip is caught by the lower edge or notch of the side wall and scooped up. Settled.

(E) Function As the rotary body rotates, the wood put into one end of the wood storage body is peeled by a large number of peeling teeth protruding from its circumferential surface, and sequentially moves to the other end, interlocking and circulating. This process is repeated, during which time the skin is discharged from the outlet at the other end.

In the wood storage body, the back plate, a piece of wood like the back plate, and a plate-shaped piece of leather are placed on a rotating body and moved to the exit side of the peeling teeth. At this time, the pieces of wood, etc. are supported by the band-shaped body and move between the adjacent peeling teeth, and when they reach the exit part, they are scooped up by both sides of the notch into which the band-shaped body is inserted and rise. , can be prevented from being caught between the lower edge of the side plate and the outer peripheral surface of the rotating body.

(F) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a wood storage body (hereinafter referred to as a storage body) which is horizontally suspended on the machine base 2 so that the delivery side is lowered, and two of these are connected in series, and an opening 3 extending approximately the entire length is provided at the bottom of the wood storage body (hereinafter referred to as the storage body). A hopper 4 protruding to the side is attached to the input port provided at the upper part of the starting end of the storage body 1 on the upper side, and this storage body 1 can be connected to the left and right side plates and the front and rear end plates. The hopper 4 may be configured to be open at the top, and in this case as well, the hopper 4 is provided at the top on the starting end side.

Further, the opening 3 of the storage body 1 is displaced laterally (on the opposite side from the hopper 4) from the vertical center line of the storage body 1 when viewed from the length direction, and has a drum-like shape pivotally supported at the bottom thereof. The upper part of the rotating body 5 is inserted into the opening 3, and a large number of high peeling teeth 6...(a is attached in a spiral shape by welding or bolts.

Furthermore, the lower part 1a of one side of the storage body 1 (the side where the skinning teeth 6 and 7 enter the storage body 1 while rising) is inclined downward from a portion facing the top of the rotating body 5 to a position approximately equal to the axis. The other side lower part 1b descends with a gentle slope to a part slightly away from the vertical diameter of the rotating body 5, and the lower edge of the one side lower part 1a and the other side lower part 1b is provided with slits 16 through which the skinning teeth 6, 7 pass, so each of the skinning teeth 6, 7... is inserted into the storage body 1 from the steeply inclined slit 16 in the lower part 1a of one side. and escape from the lower part 1b on the other side.

As shown in FIGS. 4 and 7, a plurality of rectangular plates 17 are arranged radially in the axial direction on the inner circumferential surfaces of the end portions of the rotating bodies 5, 5, which are connected in series in the front and rear directions. A shaft 18... is fixed via a shaft 18, and the shaft 18... is supported by a bearing 19... on the machine base 2, and the upper part between the rotating bodies 5, 5 is the It is covered with an arc-shaped cover 20 that coincides with the outer peripheral surface, and the shafts 18, 18 near the storage bodies 1, 1 and the protruding portion of one shaft 18 are provided with skinning circles having a plurality of teeth similar to the skinning teeth 6 on the outer periphery. The peeling disk 21 fixed to the end of the shaft 18 projects upward from the slit 22 formed in the cover 20, and the peeling disk 21, 21 near the rotating bodies 5, 5 has plates 21 fixed thereon. is the gap 23 between the cover 20 and the ends of the rotating bodies 5, 5,
Since it protrudes upward from 23, the peeling process is performed while promoting the movement of the wood from one storage body 1 to the other storage body 1.

The cover 24 provided on the discharge side of the rotating body 5 has the same shape as the cover 20 when viewed from the axial direction, but has a recess 24' below it as shown by the chain line in FIG. 2 when viewed from the side. The starting end fits into the trough 24'' of the recess 24', and the terminating end fits into the trough 24'' at a depth l of the trough 24''.
The guide plate 25 is welded to a height that rises to 2/3 of the height and has a triangular shape in plan view, so that the end of the wood to be discharged is in the valley 2.
4" and does not stick and stand up, it is smoothly discharged while being slid and guided one by one.

Therefore, pieces of wood or bark such as a backboard may get caught between the lower edge of the other side lower part 1b of the storage body 1 and the outer peripheral surface of the rotating body 5 and the slit 16. As shown in FIGS. 5 and 7, a strip 5a is attached to the outer periphery of the rotating body 5 at a portion facing between the slits 16, 16, and its outer circumferential surface is attached to the one side lower part 1
a and the lower edge of the other side lower part 1b, or by making the strip 5a thicker than the distance between the lower edge and the outer peripheral surface of the rotating body 5 and providing a notch 1d in the lower edge of the strip 5a. When a part is fitted into the notch 1d,
The aforementioned jamming phenomenon can be eliminated.

In the above-mentioned peeling machine, when logs are fed into the storage body 1 from the hopper 4 using a feeding conveyor or a lift, the peeling teeth 6 and 7 cut through the slit 16 in the lower part 1a of one side of the storage body 1, which is steeply sloped. 1
The rotor 5 supports the wood and rotates, and when the peeling teeth 6 and 7 reach the lower part 1b of the other side, the wood is peeled while pushing the wood toward the other side. The wood escapes from the slit 16, is pushed by the following wood, is scooped up by the lower part 1b on the other side, is jumped up by the peeling teeth 6, and rolls toward the lower part of the one side. It returns to 1a and is further stripped.

When the wood climbs onto the cover 20 at the end of the storage body 1 on the upper side, the peeling disc 21...
... facilitates movement while stripping the wood, so the wood is smoothly transferred to the collecting body 1 on the lower side and subjected to the same stripping treatment as described above.

Among the peeling teeth 6 of the peeling part on the lower side, the one from the outlet should be lowered to about the peeling tooth 7,
Alternatively, by making the teeth 6a smaller, it is possible to carry out final debarking to remove the remaining bark without damaging the wood, and the debarked wood is guided by the cover 24 and the guide plate 25 to the discharge port 1c. When the wood is discharged from the wood and falls onto the discharge conveyor 30, it is sorted and the wood with remaining bark is placed on the return conveyor 31 and returned to the hopper 4 for reprocessing.

Further, the bark that has fallen from the slit 16 and between the rotating body 5 and the storage body 1 is carried out by a conveyor 32 stretched downward.

When wood chips or backboards generated in the storage body 1 during such peeling work are thrown into the storage body, they are placed on the strip 5b between the adjacent peeling teeth 6, 6 and transferred to the exit side. At the exit part, if the outer periphery of the strip 5b is in sliding contact with the lower edge of the side plate 1a, the lower edge will scoop up a piece of wood, etc., and if the strip 5b is fitted into the notch 1d, the edges on both sides of the notch 1d. Since it is scooped up, the back plate and the like are not caught between the side wall 1a and the outer periphery of the rotating body 5.

As described above, the present invention involves horizontally suspending a wood storage body 1 with an open top, opening the lower part of the wood storage body 1 over approximately the entire length, and installing a drum-shaped rotating body 5 horizontally suspended below the wood storage body 1. A large number of peeling teeth 6 are protruded from the outer peripheral surface of the rotary body 5, and a circumferential strip is formed on the outer peripheral surface of the rotary body 5. Attachment: Either the lower part of the side wall of the wood storage body 1 is brought into sliding contact with the band-shaped body, or the band-shaped body is made higher than the gap between the lower edge of the side wall and the circumferential surface of the rotating body 5, and a notch is provided at the lower edge of the side wall. Since the wood chips generated during the debarking process are placed on the strip 5b between the adjacent debarking teeth 6 and 6, and move to the exit side of the debarking tooth 6, the wood chips generated during the debarking process are transferred to the exit side of the debarking tooth 6, and the wood chips are placed on both sides of the lower edge of the side plate 1a or the notch. will scoop up the backboard, pieces of wood, pieces of leather, etc.
The back plate, wood chips, etc. are not caught between the side plate 1a and the outer circumferential surface of the rotating body 5, and discharge of bark can be promoted while preventing overload from being applied to the rotating body.
