Description

[Detailed Description of the Invention] A movable bark stripping machine equipped with the above-mentioned rotary cutter is used as a conventionally known bark stripping machine that uses a rotary cutter to debark a rotatable log mounted on a machine frame mounted and fixed on a predetermined foundation. The frame is mounted on one side of the machine frame itself and runs along it, or the frame is mounted on a stand installed on the side separately from the machine frame and runs along it. There is a type that lets you do it.

However, in all of these cases, it is necessary to always secure space on the sides of the machine frame for the movement of the movable frame or installation of the pedestal. It could not be used for placing logs or installing log feeding equipment or log transfer delivery equipment.

In addition, in the above-mentioned conventional type, one side of the machine frame body opposite to the side on which the movable frame body is mounted is opened especially for the transfer and delivery of logs after peeling. Therefore, if the rotary cutter is rotated forward to avoid scattering bark pieces from the rotary cutter on this side, the bark pieces will inevitably scatter towards the rear side of the movable frame, causing the movable frame to It becomes a hindrance to the body's movement. The present invention aims to solve the above-mentioned drawbacks by proposing a straddle-type movable frame body that straddles the rock frame body so that it can move left and right, and mounts the frame body on the rear side of the straddle-type movable frame body. The gist is that a rotary cutter that sends bark pieces forward is pivotally supported at the front end of the arm body, and a hanging plate that makes the bark pieces collide and fall is stretched on the front side of the straddle type movable frame body.

Another object of the present invention is to make it possible to easily collect bark pieces by the above-mentioned structure, and to prevent the rotary log being peeled from jumping out from above the machine frame.

The present invention will be described in detail below with reference to illustrated embodiments.

A is an installation machine frame of the type that is installed and fixed on a predetermined foundation, and vertical frame members 1 and 2 of the required length are straddled in parallel on the upper surface, and a horizontal frame is installed between the vertical frame parts 1 and 2. Members 3 to 6 are installed in parallel. The vertical frame member 1 is provided with a rail 8 having a square cross section, and the vertical frame member 2 is provided with a channel-shaped auxiliary rail 9 having a front end.

10 and 11 are bearings 12 to 15 installed in each of the frame members 3 to 6.
, 16 to 19, which are supported in parallel at a required distance in the front and rear, and two drive tires 20 to 23 and two driven tires are mounted on the left and right outer sides of both shafts 10 and 11. 24 to 27 are arranged in formation facing each other.

29 is a drive motor, the rotational force of which is transmitted across the drive shaft through a chain 30, and the rotational force of the drive shaft 10 is further transmitted to the driven shaft 11 through chains 31, 31'; Therefore, by driving the drive motor 29, the tires 20 to 23, 2 attached to both the shafts 10, 11 are
4 to 27 rotate, and the tires are straddled between the tires 20 to 23 and 24 to 27, and their axes are aligned with both axles 10.
, 11 and directly placed on the log 28 is rotated.

b is a straddling type movable frame body, which includes an arch-shaped frame member 32 as a rear component, a pair of parallel spanning members 33 extending horizontally forward from the upper end of this frame member 32; 3
3', and a hanging plate 34 which is a front side component and hangs down from the front end of the spanning members 33, 33' over the entire front side.

Bracket bearings 35, 35' are installed on both outer sides of the lower end of the frame member 32, and the wheels 36, 36' supported by the bearings 35, 35' are connected to the rail 8 and are suspended. The rotating wheel 37 provided at the center of the lower end of the plate 34 is placed on the auxiliary rail 9, and the rotating wheels 38, 38' provided on both outer sides of the rotating wheel 37 are placed on the auxiliary rail 9 as shown in FIG. By contacting the lower surface of the straddling type movable frame b, the straddling type movable frame b is straddled over the rails 8 and 9 of the installation machine frame a.

Reference numeral 39 denotes a cover for a drive mechanism (not shown) attached to the lower side of the frame member 32. By driving the drive mechanism, the wheels 36, 36' are rotated, and the straddle type movable frame b It moves the .

Reference numeral c denotes an arm body mounted on the frame member 32, which is a rear component, and a rotary cutter 41 mounted on the front end of the front arm 40 is straddled between the tires 20-23 and 24-27. A motor 44 is attached to the rear arm 42 for rotating the rotary cutter 41 backward, that is, counterclockwise in FIG. is installed.

While holding the rotary cutter 41 in a relative position contacting the surface of the log 28, the log 28 and the rotary cutter 4
By gradually moving the straddle-type movable frame b along the rails 8 and 9 while rotating the movable frame 1, the bark of the log 28 can be peeled off cleanly.

During this stripping work, the stripped pieces of bark fly forward, but they hit the hanging plate 34 of the straddle type movable frame b and fall, so they do not scatter around.

As is clear from the above description, according to the bark stripping machine of the present invention, the log is supported by tires, so there is no risk of the support means damaging the surface of the wood after the bark has been stripped, and there is no reduction in its commercial value. In addition, there is no risk of slipping even when the log is wet with rainwater or its skin is frozen, and the above tire appropriately absorbs the external force or pressure applied to the log through the rotary cutter. Therefore, the logs will not be unduly pressed down or jumped up, and even logs with relatively small diameters will remain stable in the specified position, and therefore, they will rotate at high speed with the tires and perform the specified peeling work efficiently. In addition, it has the following effects.

(a) The movable frame is a straddle type and is laid across a pair of rails on the installed machine frame, and unlike conventional models, it runs on one side of the machine frame itself or on a separately installed pedestal. Therefore, it is possible to stack logs before and after peeling around the installation machine frame, and to install a log feeding device or log transfer delivery device around it, eliminating the drawbacks of the conventional method and improving work efficiency. improves.

'b' A hanging piece of bark that is peeled off by one rotary cutter at the front end of the arm mounted on the rear side of the straddle type movable frame and flies forward, stretched over the entire front side of the movable frame. Unlike the conventional type, in which the pieces of bark can be dropped against a board and stored in a predetermined position, and the pieces of bark are thrown to the rear of the machine frame, there are cases where the pieces of bark interfere with the movement of the movable frame, or when the log is transferred and delivered. It does not get in the way of estimation.

[c] As mentioned above, the movable frame is a screen type, and the logs that are being debarked may come off the tires of the installation machine for some reason because they are fighting against the front and rear rails on the installation machine frame. If it tries to jump out of the frame, it can be blocked by the front or rear side of the movable frame, avoiding danger in the surrounding area.

[d' There are two driving and driven tires for rotating the log on the left and right outer sides of the drive and driven shafts, and the two shafts are connected by chains on the left and right outer sides of the drive and driven shafts, so the drive motor The log can be rotated smoothly and in a stable state by pulling outward.
