Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a plane of an automatic plane that discharges cutting chips by utilizing the rotational force of the plane.

[Conventional technology]

In conventional small and medium-sized automatic planes, the cooling air from the motor provided at the top of the head is used to discharge cutting chips rearward or sideways in order to discharge the cutting chips generated when cutting the material to be cut. It was

However, in a large-sized automatic plane, since the motor is large and heavy, it is difficult to install the motor on the upper part of the head, and the wind dust generated when the plane is rotated discharges the cutting chips.

[Problems to be solved by the device]

However, the wind generated when the plane is rotated has the strongest wind in the central portion in the length direction of the plane, and the loss is large and the wind is extremely weak near both sides. Therefore, if the material to be cut is cut at the central part of the plane, the discharge of cutting waste is good, but if cutting at both sides, the cutting waste does not fly far and is hit twice, and further cutting clogging occurs, The cutting surface of the cutting material was significantly deteriorated. In addition, it takes time and effort to remove the cutting, and the work efficiency is poor.

The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art,
The object of the present invention is to provide double-punching and cutting debris that occur when cutting is performed at both sides in the lengthwise direction of a plane, to improve the cutting surface and work efficiency, and to provide at low cost.

[Means for solving the problem]

In order to achieve the above-mentioned object, the present invention has a head facing a table supporting wood, a frame having a plane blade driven and rotated by a motor, and a material feeding roller which are pivotally supported on the head. In one of the automatic planes, one of which can freely move up and down, a plurality of projections are radially provided on both end sides of the plane body to generate wind that flows in the circumferential direction of the plane body when the plane body is rotated. It is a thing.

[Action]

In the above configuration, when the plane is rotated, the wind flows in the circumferential direction from the center of rotation of the plane by the plurality of protrusions, and the wind on both sides of the plane becomes strong. In this state, even if the material to be cut is cut at both sides in the length direction of the plane, the cutting chips are scattered to a distance.

〔Example〕

One embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a front view of an automatic plane board showing an embodiment of the present invention, and FIG. 2 is a perspective view of a plane body end portion.

In the figure, a column 3 having one end fixed to a base 1 and the other end fixed to a head 2 in an upright state is provided.
A table 4 is hole-fitted in the column 3 between them. By rotating the lifting handle 5 on the table 4, the table 4 moves up and down via the lifting member 6 screwed to the base 1. Inside the head 2, a plane cylinder 8 having a plane blade 7 which is rotationally driven by a motor (not shown) and a material feeding roller 9
Is pivotally supported. A chip cover 12 is attached to the upper part of the plane body 8 to form a discharge path 11 for cutting chips 10 generated from the material 14 to be cut.

When the material to be cut 14 is placed on the table 4 and pushed into the plane 8 side, it is sent to the plane 8 by the material feeding roller 9 and the upper surface is cut by the plane blade 7 of the plane 8 which is rotationally driven. To be done.

As shown in FIG. 2, a plurality of protrusions 13 are radially formed on both end faces of the plane body 8.

In the above configuration, when the plane 8 is rotated, the plurality of protrusions 13 are formed in a radial pattern, so that the wind flows in the circumferential direction from the center of rotation of the plane 8 to move the plane 8 without the protrusions 13. The wind on both sides of the plane 8 is stronger than when it is rotated.

In this state, even if the material to be cut 14 is cut at both sides in the lengthwise direction of the plane body 8, the cutting chips 10 pop out of the discharge path 11 and are hit twice, and the cutting chips are not clogged.

[Effect of device]

According to the present invention, since the plurality of protrusions extending in the circumferential direction from the center of the plane are radially provided on both sides of the plane, the wind is discharged in the circumferential direction by the rotation of the plane. The wind on both sides is strong, and even if the material to be cut is cut at both sides, the cutting waste is blown away, the double impact is eliminated, and the cutting surface of the material to be cut is improved.

Further, since there is no cutting clogging, it is possible to save the labor of removing cutting chips and improve the work efficiency.

Furthermore, the above effect can be obtained and the structure can be provided at a low cost only by providing a plurality of protrusions on both sides of the plane.
