Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, a rotating shaft is installed in the lower part of a wood storage body suspended horizontally on a machine frame in parallel with the wood storage body, and a large number of striking bodies are pivotally connected to the rotating shaft. A peeling machine is already known in which the wood passes through a slit formed in the lower surface of the wood storage body.

However, since the striking body strongly strikes the circumferential surface of the wood,
In addition to damaging the wooden parts, the driving part of the hammering body may be damaged due to the impact.Furthermore, when the hammering body hits the wood, the hammering body returns due to the reaction force, which prevents the transfer and circulation of the timber. The problem was that particularly heavy wood could not be moved, and only one part of the tree would be severely damaged and bark would remain in other parts.

The present invention aims to improve the above-mentioned drawbacks and provide a peeling machine capable of improving the peeling efficiency, in which a wood storage body 1 with an open upper part is hung horizontally, and the lower part of the wood storage body 1 is opened. A part of a drum-shaped rotating body 5 suspended horizontally below the opening is opened over almost the entire length, and a part of the drum-shaped rotating body 5 enters into the wood storage body l through the opening, and a large number of peeling teeth are formed on the outer peripheral surface of the rotating body 5. 6 are arranged in multiple rows in a spiral shape, and their peeling teeth 6
The device is characterized in that part or all of it is removably attached.

The embodiment shown in the drawings will be described below.The construction is a wood storage body (hereinafter referred to as storage body) that is horizontally mounted on the machine base 2 so that the delivery side is lowered, and two of these are connected in series.
An opening 3 extending approximately the entire length is formed in the lower part of each of them, and a hopper 4 projecting to the side is attached to the input port provided at the upper part of the starting end of the storage assembly 1 on the upper side. The storage body 1 may be constructed of left and right side plates whose upper part expands in a V-shape, and front and rear end plates, and in this case as well, the hopper 4 is placed at the upper part of the starting end side.

Furthermore, 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, which has a standard radius of 730 mm,
A large number of high peeling teeth 6... (a is the rotation locus) are inserted into the outer peripheral surface of the rotary body 5 by welding or bolts so that the lower side in the rotational direction is gradually higher and has saw-blade-like teeth 6a. It is installed in a spiral shape. However, Fig. 5 (
As shown in b), in the middle of the rows of the skinning teeth 6, there are skinning teeth 7. When arranged in a spiral,
When a bent piece of wood is placed diagonally on the rotating body 5, both ends are peeled by the low peeling teeth 6, as shown in the figure, the middle part is peeled by the high peeling teeth 7, and only one end is peeled by the high peeling teeth. 6
When riding on the vehicle, the middle part is skinned by the low skinning teeth 7.

To perform such debarking, the pitch P of each row of teeth (standard 2400 mm) is made approximately equal to or slightly shorter than the length of the wood.

For example, when the skinning teeth 6 and 7 are made of a plate with a thickness of 22+am, the height of the highest part of the high skinning tooth 6 is 100 mm.
mm-120am, and the low skinning tooth 7 is 50~[10
mm or 67 to 80 mm.

Since the peeling tooth 6 or 7 will wear even if it is made of high-hardness steel or is hardened, a seat 6b is welded to the outer peripheral surface of the rotating body 5 as shown in FIG. Screw the skinning blade 6 or 7 onto 6b or
The base plate 8 shown in (c) is welded to the rotating body 5, and a large number of teeth 6 are formed.
a. A tooth tip plate 9 having a fist is removably screwed on with a plurality of bolts 10, or a base plate 8 whose upper surface is stepped as shown in FIG. A series of tooth tip plates 9 having step-like upper and lower surfaces are fitted to the base plate 8 in a "spigot" manner, and are removably screwed with a plurality of bolts 10, or as shown in FIG. Peel the base plate 8 and peel the teeth 6 as shown.
, 7, and a block 12Φ, which has a tooth tip 11 of high hardness integrally fixed to the notch at the corner thereof, is fitted and removably screwed with the pin 10. Alternatively, as shown in FIG. 11, a groove is bored in the stepped portion, and a block 12 having a tooth tip 11 and a leg portion 11a that fits into the groove is fitted and screwed, or 12th
As shown in the figure, a notch groove 8a is formed in the corner of the base plate 8, the tip side of which is narrower than the plate thickness, and the tapered tooth tip lla is fitted into the groove 8a and attached and detached with the bolt 10. If the tooth tip is screwed on, it can be easily replaced when the tooth tip becomes worn, and the peeling performance can be improved in a short period of time at a small cost.

Furthermore, if all or some of the peeling teeth 6 and 7 are tilted so that the rear side (high side) is deviated toward the direction of movement of the wood, as shown by the chain line Y in FIG. 5, the movement of the wood can be prevented. can be promoted.

However, when the bark is difficult to peel off due to the type of wood or the time of felling, or when the amount of young wood is small, the shutter 13 installed at the outlet 1c of the rear storage unit 1 may be removed from the motor 1.
4 to prevent the discharge by raising it through the chain 15, and in a so-called batch type to prolong the peeling process, the peeling tooth 6.7 located near the discharge port lc is rotated in the opposite direction to the above-mentioned one. When the front side is deviated toward the discharge port lc side, the peeling teeth 6 and 7 in opposite directions push back the wood moving toward the discharge port 1c, and the wood accumulates only near the discharge port 1c. It is possible to perform good peeling by dispersing the skin.

Furthermore, the lower part 1a on one side of the storage body 1 (the side where the peeling teeth 6°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 substantially 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 to the outside, and the lower edge of the - side lower part 1a and the other side lower part 1b Since the slits 16 through which the skinning teeth 6.7 pass are bored, each skinning tooth 6.70 is inserted into the storage body l from the slit 16 in the lower part 1a on the negative side, which has a steep slope. It enters and escapes from the lower part 1b on the other side.

As shown in FIGS. 4-5 and 13, a plurality of rectangular plates arranged radially in the axial direction are provided on the inner circumferential surfaces of the ends of the rotary bodies 5, 5, which are connected in the front and back. A shaft 18... is fixed via a shaft 17-..., and the shaft 18... is pivotally supported by a bearing 18... on the machine base 2, and these rotating bodies 5
．． The upper part between 5 and 5 is the rotating body 5 as shown in FIGS. 13 and 14.
A plurality of teeth similar to the skinning teeth 6 are formed on the outer periphery of the housing 1. A peeling disk 21 is fixed to the end of the shaft 18, and the peeling disk 21 is fixed to the end of the shaft 18 through the slit 2 formed in the cover 20.
A peeling disk 21 protrudes upward from 2 and is closer to the rotating bodies 5, 5.
．． 21 is a gap 23 between the cover 20 and the ends of the rotating bodies 5, 5.
．． Since it protrudes upward from 23, it does not encourage the movement of the wood from one container 1 to the other container 1, and then performs the peeling process.

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 concave portion 24° at the bottom as shown by the chain line in FIG. 1 when viewed from the side. The guide plate 25 has a starting end that fits into the second valley of the recess 24', and a terminal end of the guide plate 25 whose height rises to 2/3 of the depth l of the valley, and which has a triangular shape in plan view. Since the wood is welded, the end of the ejected wood is in the valley part 24'.
It is smoothly discharged while being guided by sliding without getting stuck and standing up.

Furthermore, when two storage bodies 1.1 are installed in series, the rotating body 5.
When the shafts 7, 7 of the connection part 5 are supported by bearings 19 and 19,
As the distance between the rotating bodies 5 and 5 becomes wider, the width of the cover 20 must be increased, which increases the size of the entire peeling machine and makes it difficult for the wood to move smoothly to the storage body 1 on the lower side. Therefore, reinforcing plates or rods are radially welded into the ends of the rotating bodies 5, 5, and the outer periphery of the ends is fixed as shown in Fig. 4(b).
If the cover 20 is supported from at least three sides by rollers 30.phi. as shown in FIG.
It can be formed into a narrow piece that can be covered over, reducing the overall length of the device and smoothing the transition of the wood.

Furthermore, a piece of wood 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 circumferential surface of the rotating body 5 and the sling 18, so as shown in FIG. 4(C). As shown in , a band 5a is attached to a part of the outer periphery of the rotary body 1 facing between the slits iB and 1f3, and its outer peripheral surface is connected to the lower part 1a on the negative side.
Alternatively, the band 5a may be made to be in sliding contact with the lower edge of the lower portion 1b on the other side, or the band 5a may be made thicker than the distance between the lower edge and the outer circumferential surface of the rotating body 5, and a shallow groove 1d may be provided in the lower edge so that a part of the band 5a is By fitting into the groove 1d, the above-mentioned jamming phenomenon can be eliminated.

In the above embodiment, the storage bodies 1, 1 were fixed to the machine base 2, but
As shown in FIG. 16 (only the upper side is shown), the motor, rotating body 5, and its bearing 19 of the storage body 1.1,...
etc. are attached to the inclined table 28, and the connection side of the inclined table 28 is supported by a support shaft 29 so as to be tiltable up and down, and the upper inclined table 28
is supported via a jack 27 so that it can be raised and lowered, and the terminal end of the storage body 1 on the lower side and the bearing 18 are supported by the jack 27.
When supported so that they can be raised and lowered at 7, the inclination angle of the storage bodies 1, 1 can be adjusted according to the time of felling the timber, the difference in the difficulty of peeling depending on the tree species, or the difference in mobility due to the size of the diameter, etc., so that there is insufficient peeling This prevents the wood from becoming damaged or being damaged by excessive peeling. If there is only one peeling machine, it may be tilted using the middle part as a fulcrum as shown in FIG.

In the above-mentioned peeling machine, when logs are loaded from the hopper 8 into the storage body 1 using a feeding conveyor or a lift, the peeling teeth 6 and 7 insert the logs into the storage body from the slit 16 in the steeply inclined lower part 1a of the storage body l. 1 and peels the wood while pushing it up toward the other side. At this time, the rotating body 5 supports and rotates the wood, and when the peeling teeth 6 and 7 reach the other side lower part 1b.

The wood escapes from the slit 16 on that side, 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 on the - side, while The peeling process shown in FIG. 5(b) described above is applied to the peeling process, and the peeling process is carried out again in the negative side lower part 1a.

When the wood reaches the cover 20 at the end of the storage unit l on the upper side, the peeling discs 21 promote the movement while peeling the wood, so that the wood smoothly transfers to the storage unit l on the lower side. Then, the skin is peeled off in the same way as described above.

The part from the ejection port of the peeling part #R6 and fist on the lower side should be made as low as the peeling tooth 7, or the tooth 6a-
If 9 is made small, it is possible to carry out final debarking to remove the remaining bark without damaging the woody part, and the debarked wood is guided by the cover 24 and the guide plate 25,
The wood is discharged from the discharge port IC, and when it 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 pickpockets 7) 18 and the bark that has fallen from between the rotating body 5 and the storage body 1 are carried out by a conveyor 32 stretched downward.

If the peeling teeth 6, 7, etc. become worn out during such peeling work, replacing them as shown in FIGS. 7 to 12 will improve the peeling efficiency at once with a simple operation.

I As described above, the present invention comprises a wood storage body 1 which is open at the top and which is horizontally suspended, the lower part of the wood storage body 1 is opened over approximately the entire length, and a drum-shaped rotatable body 5 which is horizontally suspended below the wood storage body 1. A part of the rotating body 5 enters into the wood storage body l through the opening.
A large number of stripping teeth 6 are arranged in multiple rows in a spiral shape on the outer circumferential surface of the wood, and some or all of these stripping teeth 6 are detachably attached, so that the wood can be attached to the stripping teeth 6 and the rotating body 6. This makes it possible to reliably transfer and circulate the material while forcibly lifting it up, and also to peel the skin.Moreover, when the skinning teeth 6 become worn, the extremely simple operation of replacing them makes it possible to significantly improve the peeling performance. .
