Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a log peeling device, and its purpose is to detect when a log is present, regardless of the diameter of the log, and a feed roller automatically transfers the log to a cutter disk. To provide a peeling device that can be fed while pressing.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The peeling device according to the present invention has a cutting edge rotating direction 2a on one side of a log peeling surface plate 10 with respect to the surface of the surface plate. A debarking cutter disk 2 is provided at almost right angles, a cone feed roller 3 is used to feed the log A while pressing against the disk, and the roller is used to keep the log A constant against the surface plate 1 and the disk 2. A moving device 4 for moving in the direction of pressing up to the pressure; and a moving device 4 for detecting when logs are present at the front of the surface plate 1 and sending a movement command to the moving device 4 in the direction of approaching logs, and when there are no logs, the moving device 4 and a sensing device 5 for sending a command to move away.

The moving device 4 includes an arm 6 which rotatably supports the feed roller 3 at its tip and whose center portion rotatably supports the surface plate 1 via a shaft 6a, and a rear end of the arm 6. The arm rotation hydraulic cylinder 7 is connected to the end and rotatably supported on the surface plate 1.

Further, the sensing device 1. An automatic return type push roller type bumper 8 is provided on the front part of the surface plate 1 and is retractable from the surface thereof.
and a control section 9 that controls the oil supply and drainage of the hydraulic cylinder 7 by the protruding and retracting operation of the bumper.

Note that 10 is a hydraulic motor fixed to the arm 6 to rotate the cone feed roller 3 in the direction of arrow B; 11 is a chain that transmits the power of the motor 10 to the roller 3; and 12 is a claw 12a on the surface. The chain 12 has a pair of left and right sprockets (13a).

13b, the log A is suspended so as to be movable in the direction of the arrow C, which sends the log A to the disk 2 side.

Further, the disk 2 is rotatable around the horizontal axis 14 in the direction of the arrow D shown in FIG. has been done.

16 is a holding plate for the blade; 17 is a fixing member for the holding plate 16;
Numeral 18 is a bolt for fixing the blade 15 to the disk 2, and 19 is a fixing plate.

Further, 20 is a drive hydraulic motor for the feed chain 12, 21 is a power transmission chain thereof, 22 is a hydraulic pump,
23 is a hydraulic tank, and 24 is a disc cover.

The cone feed roller 3 has a spline groove 3a formed on its roller surface, and the roller 3 and the underfeed chain 12 are twisted at an arbitrary angle with respect to the disk 2.

Reference numeral 25 denotes a mounting tool for detachably attaching the surface plate 1 to a vehicle body such as a tractor, and 26 indicates the hydraulic pump 22.
The pump 22 is used to rotate the
This is a connector that connects the 0-rotation shaft and the tractor-side rotation shaft.

Next, the action will be explained.

To debark the log A, the cutter disk 2, cone feed roller 3, and underfeed chain 12 are rotated, respectively, and the log A is carried into the space formed by these.

Then, the bumper 8 of the sensing device 5 is pressed by the log A and is activated, and the control unit 9 sends a command to move toward the log toward the moving device 4.

Then, the hydraulic cylinder 7 is actuated to rotate the arm 6 and automatically bring the cone feed roller 3 into contact with the log A.

The log A is rotated by the rollers 3 and moved to the disk 2 side by utilizing the difference in peripheral speed of the rollers 3.

At this time, the underfeed chain 12 also moves the log in the C direction.

Since the rollers 3 and the chain 12 are twisted at a certain angle with respect to the disk 2, the log A moves forward while rotating in a spiral manner.

At this time, the raw wood A is debarked by the plurality of blades 15 of the rotating disk 2.

Most of the peeled skin falls into the disc cover 24 and is discharged to the outside.

Then, when the log A passes the bumper 8, the bumper 8
will automatically return.

Then, a separation direction movement command is sent from the control unit 9 to the moving device 4, the hydraulic cylinder 7 is activated, and the arm 6 is rotated in the direction in which the roller 3 is separated from the log A.

As is clear from the above description, the present invention includes a cutter disk for peeling logs, the cutter disk for peeling logs being provided on one side of a surface plate for peeling logs with the rotating surface of the cutting edge substantially perpendicular to the surface of the surface plate, and the logs being pressed against the disk. a feed roller for feeding the log while moving the log; a moving device for moving the roller in a direction to press the log to a constant pressure against the surface plate and the disk; a sensing device that senses and sends a command to move the log toward the moving device to the moving device; and a sensing device that sends a command to move the log away from the moving device when there is no log, the moving device;
an arm having a tip rotatably supporting the feed roller and a central portion rotatably supporting the surface plate via a shaft;
The sensing device is composed of a hydraulic cylinder that generates a constant pressure for rotation of the arm, which is interposed between the rear end of the arm and the surface plate. It is composed of a push roller type bumper 8) and a control section that controls a hydraulic cylinder based on a sensing signal from the push roller bumper 8).

Therefore, according to the present invention, the presence of logs can be sensed regardless of the diameter of the logs, and the feed roller can feed the logs while automatically pressing against the cutter disk. It is not necessary to manually press the log against the log, improving work efficiency, and since the log is pressed against the cutter disk at a constant pressure, the peeling thickness can be kept constant and at a minimum, and an economically superior peeling device can be provided. .
