Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood debarking device for debarking wood bark. Since stripping of the bark is essential in many cases when using wood, several types of stripping have been provided in the past. However, in these methods, the wood to be debarked must be cut to a length of 70 to 120 scratches in advance. Items that reduce performance due to friction scratches and breakage, items that cannot be applied to water wares that have curved or recessed parts, and items that require 10% to complete the peeling of 4 pieces of wood.
Each method has its own problems, such as requiring several minutes of time to remove the skin, resulting in only a few cubic meters of skin being removed per hour, or the vibration, noise, or pollution generated by the device having a negative impact on the surrounding area.

The present invention has been made in view of the above-mentioned current situation, and provides a wood peeling device that can effectively peel wood having various shapes all at once and does not have a negative impact on the surrounding area due to vibration, noise, pollution, etc. This is what we intend to provide.

The configuration of the present invention will be explained below based on examples. The two frame plates (7) are installed at the upper part of the pedestal (9) so that the rear side is high and the front side is sloped low. A number of bearings (3) are installed in the lower part 1 of the frame plate (7). And two foot plates (7) and a pair of bearings (3) which are arranged in a K device and face each other.
Both ends of one peeling roll (1) are rotatably held by the roller. In this case, the centers of the bearings (6) installed on the rail plate (7) should not all be on the same straight line, that is, a pair of bearings should be placed at positions protruding from the upper blade every few bearings. Arrange to exist. A peeling roll (1) is rotatably held at a position below the frame plate between two frame plates (7) installed at both ends of the frame at an angle, with its axis perpendicular to the diagonal direction of the frame plate. , and a large number of peeling rolls are held in parallel with the same inclination as that of the frame plate, and every few peeling rolls are held in an upwardly protruding position. The shaft of the peeling roll (1) is longer than the distance between the two frame plates, so it passes through the frame plate, so the hole for this is located at the center of the bearing (3) +1
Of course, it can be provided on the side frame plate (7).

The peeling roll has a cylindrical shaft shape, and a peeling tool (2) is provided at a portion corresponding to the space between the two frame plates (7). Both ends are rotatably held by the bearings (5), and a belt pulley (4) for rotational driving is installed at one shaft end. Since a large number of such peeling rolls (1) are installed between two frame plates (7) as described above, L is in this case one roll driving motor (6).
) is set so that the V-belt (5) is sequentially wound around each V-belt wheel (4) and rotates in the same direction. The equipment is such that peeling rolls are arranged alternately and the spacing between each peeling roll is equal to or less than one length of the wood to be peeled. The device is attached to the different groups of peeling rolls arranged alternately as described above.The belt wheels (4) are installed on different sides for each group and project to the frame plate (with different forces).Also, the rotation of the peeling rolls The speed is set so that the upper rotational direction of the peeling roll (1) is slightly higher than the rotational speed of the peeling roll (1) from the rear to the front.

The peeling knife (2) is formed by integrally forming several band-shaped protrusions with a rectangular cross section that are wound spirally around the outer circumference of the peeling roll (1) in a symmetrical shape centered on the center of the peeling roll (1). 7 can be applied to many tree species, but for tree species that have many protrusions or depressions on the surface or have thick and hard bark, a sharp knife can be attached and detached from the outer periphery of the peeling roll (1) using bolts. equipment that is installed properly will produce favorable results.

Next, the present invention will be explained in detail. If the wood is placed between two slanted frame boards (7) parallel to the frame boards, the wood will be removed from the peeling roll (1) placed below the frame boards.
). In this case, the spacing between the peeling rolls is set to less than or equal to the length of the wood, so the wood is always in contact with two or more peeling rolls, and at the contact area, the peeling blade (2) rotates due to the rotation of the peeling rolls. The bark is peeled off due to friction and collision. In this case, the alternately arranged peeling rolls rotate in different directions, and the rotation speed in the direction of moving the wood backwards and forwards is set slightly higher than in the opposite direction, so the inclination of the peeling rolls and Together, they move forward at a very small speed. In this way, while the wood passes over a large number of peeling rolls at a very low speed, the entire surface of the wood is subjected to sufficient friction and collision □(5) to be peeled. In addition, during the frictional collision between the peeling knife and the wood, the wood is in a stationary state, so the sound generated and vibrations transmitted to the outside of the device are significantly smaller than in conventional peeling devices that use dropping, stirring, hitting, etc.

Further, when a curved water cone is placed on the peeling rolls provided every few pieces to protrude upward, the inner peripheral surface of the curved portion will not come into contact with the peeling knife, and the peeling of that part will be performed.

In order to perform good peeling, it is desirable that the core of the peeling roll and the core of the wood be in direct alignment. For this reason, a wood sorting board (1) with a height of 1 less than the height of the frame board (1) is placed on the peeling roll in a state perpendicular to the axis of the peeling roll, that is, parallel to the two frame boards It is preferable to do so.

Further, more favorable results were obtained when the peeling roll was slightly shaken to level the posture of the wood immediately after loading and to maintain the Ka of the peeled bark. This oscillation is caused by the frame plate (
7) was swingably supported by a coil spring (1) and was carried out by a swing motor (14) (6) via a crankshaft (12) and a flywheel (16).
