Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a wood debarking machine, and more specifically to an oven-type wood debarking machine that allows easy loading and unloading of logs.

[Prior Art] When peeling the bark of a chip log as a pre-process for producing chips, a peeling machine called a drum barker is generally used.

An example of this peeling machine is the Japanese Patent Publication No. 45-1. As described in Publication No. 28528 or Japanese Patent Application Laid-open No. 185106/1983, a single rotating shaft is installed horizontally below a cylindrical can fixed on the machine frame, and a number of rotating shafts are mounted on this rotating shaft. A configuration in which individual hammering rods or peeling plates are attached, and as the rotating shaft rotates, these beating rods or peeling plates protrude into the can body through a slit provided at the bottom of the can body, and strike the logs placed inside the can body. However, with this type of construction, the logs are transported into and out of the can using a narrow opening or hopper, making it extremely difficult to work, making a lot of noise, and being a closed type. There was a drawback that it was difficult to monitor the debarking status of the logs inside the can.

On the other hand, 57-197014 as one without JP-A-Sho
The publication describes an example in which a semi-cylindrical can body is used, but in this case, the workability of transporting raw wood into the can body is much improved compared to the previous example, but the raw wood after debarking is There is a problem with workability when removing the can from the can body.

[Objective of the invention 1] This invention eliminates the above-mentioned drawbacks, and provides a method for debarking wood that makes it easy to transport logs, has a large debarking effect, generates little noise, and makes it easy to carry out the logs after debarking and store and carry them out of parks. The purpose is to provide opportunities.

[Summary of the Invention] In order to achieve the above-mentioned object, this debarking machine is provided with a debarking machine that stores logs carried in from above a debarking rotor which is pivotally supported on a machine frame and has a large number of debarking notches attached to the outer periphery of the rotor. The raw wood after debarking can be carried out below the rotor by changing the state of part or all of the means at the time of carrying out. An embodiment of the present invention shown in the drawings will be described in detail below.

[Embodiment of the Invention] The peeling machine of the present invention is mounted on a pedestal 3 installed horizontally between supports 2 constituting a machine frame 1 as shown in Figs. 1 to 3, and as shown in Figs. 4 and 5. As shown, it passes through end plates 5 attached to both ends of a cylindrical body 4 whose diameter is sufficiently larger than the maximum diameter of the log to be debarked! A rotor shaft "7" with a key attached thereto is rotatably mounted via a bearing 9, and a motor 12 is connected via a chain 11 to a chain wheel 1o attached to one end of the shaft 6. On the outer periphery of the body 4, there is a peeling notch made of cemented carbide with saw blade-like teeth formed along the line 2-2, which is gently sloped in order to avoid damaging the woody part of the log in the direction of rotation of the cylinder. 8 are spirally attached at regular intervals, and as the rotor shaft 7 rotates, the logs placed thereon can be moved in the longitudinal direction of the rotor shaft.

As shown in FIGS. 1 and 2, on the - side column 2, a carrying live deck 13 and a fixed chute 14'tfi which is inclined from the end of the live deck toward the axis of the rotor shaft 7 are installed between the columns. The logs a are carried in from above the rotor shaft. Incidentally, this fixed chute may also have the same -U configuration as the movable chute described later.

Movable chute 1 with a back reinforcement frame attached to support 2 on the other side
A piston rod 20 of a hydraulic cylinder 19 is attached to the other end of a lever 18 whose one end is fixed to the shaft 17. are connected, and the position of the movable chute 15 can be varied within a certain range by operating the hydraulic cylinder.

As shown in FIG. 1, this movable chute 15 is curved outward to facilitate the rotation and revolution of the log, and has a notch at its tip large enough to allow the peeling notch 8 attached to the rotor shaft 7 to pass through. When in the first state as shown in FIG. It has a function of ejecting the raw wood that was on the rotor shaft while the second state shown in the figure was reached.

A scraper made of rubber is formed in the horizontal bar 22 attached under the frame 3 through a mounting bracket 23 to form a notch through which the peeling notch 8 passes, and whose edge is elastically opposed to the surface of the cylindrical body 4.
24 is attached so that park adhering to the surface of the rotor shaft 7 can be removed.

A comb-shaped bridge chute 25 is attached to the horizontal beam 22, and when the movable chute 15 described above retreats to the second state, the logs to be debarked and discharged are transferred to a live deck 26 installed horizontally on the pillar 2. At the same time, the perk is collected in a hopper 27 through a gap and is discharged by a belt conveyor 28 disposed below.

The debarking machine of the present invention is constructed as described above, and the process of debarking the log will be described below.

Logs a cut to a certain length are sorted in advance according to tree species, shape, freezing, drying, etc., and then transported to the live deck 13.
The movable chute 15 is moved to the first position by the operation of the hydraulic cylinder 19.
1, 2 and 6, and logs can be stored on the rotor shaft 7 with the fixed chute 14.
As shown in the figure, it falls onto the rotor shaft 7 which is rotating counterclockwise due to the operation of the motor 12, is pushed toward the movable chute 15 by the peeling notch 8, is lifted onto the curved chute, and rotates on its own axis. Also, while reversing the revolution, a plurality of logs a are carried in from the carry-in live deck 13 located on one end side of the rotor shaft 7, and are transferred to the other side by a peeling notch 8 spirally attached to the cylindrical body 4. In between, the skin is peeled off using the serrated tooth-shaped part of the peeling notch.

The part of the park peeled off by this peeling operation that comes out from the notch 21 of the movable chute 15 passes through the bridge chute 25 and is stored in the hopper 27.

Since it is in an oven state, by controlling the swing angle of the movable chute 15 and the rotation speed of the motor 12 while monitoring the peeling state of the raw wood, it is possible to peel even curved and small diameter trees without breaking them.

When the skinning is completed, the motor 12 is stopped and the hydraulic cylinder 19
When the cylinder is stopped, the internal pressure of the cylinder decreases, and the movable chute 15
rotates counterclockwise and enters the second state shown in Figure 7,
By slightly rotating the rotor shaft 7, the debarked log a and the park fall onto the inclined bridge chute 25, the log is carried out onto the carrying-out live deck 26, and the park is stored in the hopper 27. , and are carried out of the peeling machine by the live deck and the belt conveyor 28, respectively.

Thereafter, the bark of the log can be continuously peeled in the same manner.

[Effects of the Invention] As described above, the present invention provides means for storing logs carried in from the upper blade of a peeling rotor, which is rotatably supported on a machine frame and has a number of peeling notches attached to the outer periphery, on the rotor; By varying the state of part or all of the means, the debarked raw wood can be carried out below the rotor.
Carrying in and out of the logs and separating the logs from the park after debarking are easy, and since they are in an oven, it is easy to monitor the debarking state, so appropriate control measures can be taken based on the monitoring results, making the debarking effect more visible. It has the following effects: high performance, low noise, and easy installation.
