Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a wood peeling machine for peeling wood for use in construction or pulp.

(b) Prior Art Conventionally, a wood container having upper and lower openings is attached to a machine frame, and the upper part of a rotating body having a number of skinning blades on the outer periphery is inserted into the lower opening of the wood container. machine is already known.

(C) Problems to be Solved by the Invention The above-mentioned known peeling machine sequentially transfers the wood input from the starting end of the wood container toward the terminal end while debarking the wood using a peeling blade that rotates together with a rotary body. Since the oil was discharged from the end, multiple rotating bodies were installed in series or in parallel to make it suitable for debarking wood whose bark is difficult to peel off, such as wood felled in winter, hard-barked hardwood, or frozen wood. When arranged and configured in a large size, wood cut in the spring,
Soft coniferous trees were subjected to excessive debarking and their woody parts were damaged.

Furthermore, if the wood debarking machine is configured to be small enough to be suitable for wood whose bark is easily peeled off or soft materials, the wood whose bark is easily peeled off will produce residual bark.

(d) Means for solving the problem In order to solve the above-mentioned problem, the wood debarking machine is constructed in a large size so that it can sufficiently debark wood that is difficult to debark. An attempt was made to reduce the amount of peeling by feeding wood to the starting end of the wood container and feeding wood that is easy to peel to the middle of the wood container. Since the slope is only 3 degrees downward, the wood that has been put in will collapse and move from the place where it was thrown to the starting end of the wood container, and the movement of this wood will be hindered by the wood that was put in after that, so the woody part will be significantly damaged. Damaged.

The present invention provides a peeling machine in which a wood container having upper and lower openings is mounted on a machine frame, and the upper part of a rotating body having a peeling blade on the outer periphery enters into the lower opening of the wood container. When processing wood that is difficult to debark by installing a partition in the middle so that it can be in a working position and a non-working position, the partition plate is set in a non-working position and the wood is placed at the starting end of the wood container. When processing wood or soft materials that are easy to peel, the above-mentioned problems can be solved by dividing the middle part of the wood container with a partition plate to create a working position and reducing the amount of peeling. did.

(E) Action When debarking wood that is difficult to debark, such as wood felled in winter, hardwood, or frozen wood, put the partition plate in the non-operating position and insert the wood from the beginning of the wood container.The wood will rotate. The entire body can be skinned with a skinning blade to achieve complete skinning.

In addition, when debarking coniferous trees or wood felled in the spring, if the partition plate is placed in the working position and the wood is thrown into the lower side of the partition plate, the wood that is thrown in and tends to collapse toward the starting end will be removed from the wood. Since the partition plate catches the wood, the wood thrown in later is only placed on top of the wood thrown in earlier and does not move to the starting end, and the wood at the bottom gradually moves to the discharge section at the end due to the rotation of the rotating body. No excessive exfoliation.

(F) Example An example of the present invention will be explained with reference to the drawings.
The wood container 1 is open at the top and bottom and has a discharge port 1.
It is gently sloped so that the c side is lower, and below it is a cylindrical rotating body 3, 3 with a large number of peeling teeth 2 fixed to a spiral run on its outer peripheral surface.
These rotary bodies 3, 3 are arranged in series and supported pivotally.
The upper part of the side plate 1a is partially fitted into the lower opening 4 of the wood container 1, and the lower part of the side plate 1a on the side where the peeling teeth 2 of the rotor 3 of the wood container 1 scrape up the wood is Curved toward the top, the other side plate 1b
The lower part of the side plate 1a, 1b is inclined downward and approaches the circumferential surface of the rotating body 3, and the lower edges of these side plates 1a, 1b are provided with comb-shaped notches 5 through which the skinning teeth 2 pass. . Further, between the plurality of notches 5, there are provided notches similar to the notches 5 or shallow notches 5a as shown in FIG. 4, which correspond to the notches 5a of the rotating body 2. A band 6 or a plurality of protrusions of appropriate length are welded to the portion to prevent a piece of wood from being caught between the lower edge of the side plate between the notches 5, 5 and the rotating body 3, and the above-mentioned The band 6 or the row of protrusions may be provided on the same circumference as the skinning teeth 2, and in this case, a partition plate 12, which will be described later, is lowered to the lower side of the skinning teeth 2. Furthermore, the upper part of the bearing at the connection between the front and rear rotating bodies 3, 3 is covered with an arc-shaped guide plate 7 that matches the outer circumference of the rotary body 3, and a taper is provided on the outer circumference of this guide plate 7 so that the discharge port 1c side has a larger diameter. The upper receiving ring 7a or protrusion is fixed.

The upper portions of the side plates 1a and 1b of the wood storage body 1 are curved inwardly, and a portion of this curved portion corresponding to the receiving ring 7a or a portion corresponding to the rear edge of the band 6 is cut out to form a guide. A gate-shaped support frame 9 is provided upright at a portion corresponding to the guide grooves 8, 8, and a guide groove 10 provided inside the support portion of the support frame 9; The partition plate 12 fitted into the guide grooves 8, 8 and the guide bodies 11, 11 provided on the inner surfaces of the side plates 1a, 1b is suspended by the wire 15 of the hoist 13 on the support frame 9. When the hoist 13 is driven to rotate in the forward and reverse directions, the partition plate 12 moves up and down, and when it descends, its lower end is received by the receiving ring 7a of the guide plate 7 or the edge of the band 6 near the discharge port 1c. It slides into contact with the circumferential surface of the rotating body 3 in the state of being held.

The lower end of the partition plate 12 may be configured in a shape that matches the curved portion of the side plate 1a or the inclined portion of the side plate 1b and the circumferential surface of the rotating body 3, or the side on which the wood circulating due to the peeling process moves downward is a second side. The wood thrown into the discharge port 1c side of the partition plate 12 in a lowered state below the position indicated by the dotted line in the figure is prevented from collapsing to the upper side of the partition plate 12.

Further, the guide bodies 11, 11 provided on the inner surfaces of the side plates 1a, 1b are configured by a pair of guide protrusions 16, 16, or by fixing the guide protrusions 16 only on the feeding side, and Upper guide protrusion 1
6 is designed to have a horizontal cross section in the shape of a right triangle with the lower side gradually becoming higher so as to receive both sides of the partition plate 12 on a vertical surface so as not to become an obstacle to the movement of the wood.

Furthermore, the position where the partition plate 12 is provided is not limited to the part corresponding to the receiving ring 7a or the band 6, but if it is provided in a part other than that, the guide body 11 may be provided with a pair of guide protrusions 16, 16. It guides and receives the partition plate 12,
In this case, it goes without saying that guide grooves 8, 8 are provided in the curved portions of the upper portions of the side plates 1a, 1b.

Note that if the upper portions of the side plates 1a and 1b are formed straight, the guide groove 8 can be omitted.

In addition, a vertical groove (vertical length A) is bored in one side plate 1a or 1b, and guide rails 18, 18 are connected to the upper part of this groove A on the outside of the lower part, so that the partition plate 12 can be horizontally moved. The lower end of the partition plate 12 inserted into the wood container 1 is received by the band 6 or the receiving ring 7a, and the front end is moved forward and backward from the other side plate 1b or 1a. It may be received by a guide body 11 provided on the inner surface.

Reference numeral 19 is a cam plate whose lower part is approximately equal to the outer peripheral surface of the rotary body 3 and whose high part is raised in an arc shape at one or more places up to approximately the same height as the skinning teeth 2, and is fixed to the end of the rotary body 3. A rotary cam plate 19a is also attached to the shaft 20, which intermittently pushes up the moving wood to promote its movement and has a raised portion on its outer periphery. 21 is an input section, 22 is an input conveyor, 23 is a scrap conveyor, 24 is a material conveyor, and 25 is a shooter.

In the above-mentioned wood peeling machine, when peeling wood that is difficult to peel, the partition plate 12 is raised by the hoist 13, and the rotary body 3 is driven to move a large number of pieces of wood to the starting end side of the wood container 1. When the wood is loaded, the peeling teeth 2 roll the wood from right to left in Figure 1, peeling it and scraping it up.The scraped wood circulates to the right and is further subjected to the peeling process, and the peeled wood is It climbs over the lowered shutter 17 and is carried out from the discharge port 1c.

Also, when peeling wood that is easy to peel, depending on the degree of peeling, lower the partition plate 12 on the guide plate 7 or the partition plate 12 above the band 6 of the rotating body 3 on the upper side in the wood movement direction. When the wood is put into the lower side of the partition plate 12, the partition plate 12 receives the wood and prevents it from collapsing to the upper side, and the peeling process is performed only on the lower side of the partition plate 12.

At that time, the partition plate 12 has its lower part connected to the band 6.
Alternatively, it is received by the receiving ring 7a, and if the partition plate 12 is provided in a region where the band 6 or the receiving ring 7a is not provided, it is received by the guide bodies 11, 11 of the side plates 1a, 1b.

(G) Effects of the Invention As described above, the present invention includes a wooden container 1 having upper and lower openings mounted on a machine frame, and peeling teeth 2 on the outer periphery.
In a peeling machine in which the upper part of a rotary body 3 having... is inserted into the opening 4 at the bottom of the wood container 1, a partition plate 12 is provided in the middle of the wood container 1 so as to be in an active position and a non-active position. Therefore, when debarking wood whose bark is difficult to peel off, sufficient debarking can be performed by retracting the partition plate 12 to take a non-working position and inserting the wood into the starting end side of the wood container 1. In addition, if the wood is easily peeled, divider plate 1
2 is lowered and thrown into the discharge port 1c side of the partition plate 12 for peeling treatment, it is possible to perform appropriate peeling without scraping off the woody parts.
