Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, a plurality of slits are bored in a cylindrical body supported on a machine frame, and a peeling plate that passes through the slits while rotating is rotated to a portion facing these slits, and is pivoted by a rotating shaft. A peeling machine is already known in which the wood supported and placed in the joints is peeled using the peeling plate.

However, in the peeling machine, peeled bark and scraped wood chips in the cylindrical body become clogged on the exit side of the stripping plate of the slit, which damages the peeling plate and prevents the transfer and circulation of the wood. There were drawbacks such as inhibiting the attack and reducing sword skin efficiency.

The present invention is aimed at improving the above-mentioned drawbacks, and includes providing a plurality of slits in a cylindrical body supported on a machine frame, and a rotating shaft in a portion of the cylindrical body facing the slits. , a peeling plate having an uneven outer periphery is attached to the rotating shaft so that the peeling plate rotates from one side to the other within the slit, and a side portion of the slit on which the peeling plate exits. It is characterized by having a blade attached to it.

Hereinafter, the embodiment shown in the drawings will be described. In FIGS. 1 and 2, 1 has a hopper 2 at the top of one end,
It is a cylindrical body with a discharge port 3 at the other end, and a number of circumferential slits 4 are bored in the lower part at narrow intervals in the length direction of the body. The three legs of the outlet are mounted on the machine frame 5 so that they are lower. Reference numeral 6 denotes a rotating shaft supported below the cylindrical body 1, and an equilateral triangular peeling plate 7.
are fixed with screws at the same intervals as the slits 4, and the corners 7a of the peeling plate 7 are formed in an arc shape with a small radius, and the adjacent corners are formed into an arc shape part 7b with a large radius of curvature. death,
A large number of protrusions 7c... are provided on its entire circumferential surface.

Furthermore, when the peeling plate 7 passes through the slit while rotating, the part of its outer periphery with the smallest distance from the ball core approximately coincides with the inner peripheral surface of the slit 4, or slightly protrudes from it. It is not noticeable in young people.

Reference numeral 8a is a shoulder cutting blade which is screwed onto the end of the slit 4 on the scraping side and cuts the wood chips or bark scraped by the peeling plate 7.

Next, other examples of the peeling plate 7 will be explained with reference to FIGS. 3 and 4. FIG. 3 shows an example in which the peeling plate 7 has an oval shape, and the example shown in FIG. 4 shows the eccentric position of the disc. is attached to the rotating shaft 6.

In the above-mentioned apparatus, when a peeled log is fed from the hopper 2 by an appropriate means, the peeling plate 7... rotates and peels the cylindrical body 1 from the part where the distance from the rutting core is small to the part where it is large. The protrusions 7c on the outer periphery scrape off the bark while firmly supporting the log, pushing it up from one side to the other and rotating it, until the log is at the corner (or inertial circle). When the log rolls backward in the rotational direction from the long diameter part of the log and the eccentric disk, the log descends while being subjected to rotational force and the action of the blade.

While the log is repeatedly subjected to the circulation action and the skinning action due to such rotational force, the log moves to the discharge port 3 and is completely skinned.

In the above-mentioned peeling process, the peeling plate 7 locks the scraped bark and wood pieces on its protrusion 7c, so when the peeling plate 7 leaves the slit 4, it will not get caught on the end of the slit 4 and accumulate. The bark, etc., is caught by the cutting blade 8a and is forcibly cut off as the peeling plate 7 rotates, and the cut bark, etc. falls as it is, remaining inside the cylindrical body 1. When it circulates with the log and then descends, it falls from the slit 4 and ends up giving excessive resistance to the peeling plate 7,
It does not obstruct the round rolling circulation.

Next, to explain the peeling machine shown in Figs. 5 to 7, the peeling plate 7' is an arc-shaped plate having a large number of protrusions 7c...
Mounting holes are provided at both ends, and a large number of mounting plates 8 are attached to the rotating shaft 6 at intervals, and pivots 9 are attached to the four corners of the mounting plates 8. The peeling plate 7' is attached to the pivot 9 in the narrow part of the cylindrical plate 1, and the base of the striking plate 13 is rotatably attached to the pivot 9 in the wide part. On the exiting side, there is a shaft rotating in the same direction as the rotating shaft 6. A shaft 11 is provided, only the slit 4 through which the peeling plate 7' passes is lengthened toward the sub-shaft 11 side, and a rotary plate 12 is fixed to a portion of the rutting shaft 11 corresponding to the peeling plate 7'. A circular scraping and beating body 13' is attached to the outer periphery of the
Because the base of the slit 4 is rotatably supported, the scraping and beating body 13' scrapes off the bark, etc. that is deposited on the end of the slit 4 when the peeling plate 7' leaves the slit 4. At the same time as lifting and eliminating the logs, the logs are knocked up to promote rolling and circulation of the logs. In addition, since the distance between the rear side of the peeling plate 7' in the rotational force direction and the rotating shaft 6 is larger than the distance between the front part and the rotating shaft 6, when the peeling plate 7' rotates, the log is forcibly pushed up. The logs are peeled while being transferred and circulated, and between them, the beating plates 13 . . . peel the logs while hitting the circumferential surface of the log.

As described above, the present invention provides a plurality of slits in a cylindrical body supported on a machine frame, a rotating shaft in a portion of the cylindrical body facing the slits, and A peeling plate having an uneven outer periphery is attached so that the peeling plate runs inside the slit from one side to the other, and a shoulder cutting blade is attached to the end of the slit on the side where the peeling plate exits. Therefore, when the peeling board exits from the slit, it tries to catch bark or wood chips and come out, but the Hijaku-kiri blade catches it and cuts it, preventing the bark or wood chips from getting caught at the end of the slit. It is possible to prevent loads from being applied to each part or from accumulating at the ends of the slits and impeding rolling and circulation of the log.
