Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a woodworking plane cutting machine equipped with a rotating cutter.

(Prior Art) A woodworking plane cutting machine equipped with a plane rotating cutter that rotates in contact with the workpiece fed by a material feeding table or a material feeding belt on the table is disclosed in Utility Model Publication No. 59-3848 and Japanese Utility Model Publication No. 59-3848. No. 3849 and No. 57-3850, etc., as shown in FIG. In order to prevent this, a mechanism is also known in which a rotatable holding table d is provided via a bearing c. In the above example, the presser table d is pressed against the workpiece b to prevent it from rotating. However, since the rotating cutter a must be horizontally rotated before the workpiece material d is sent, the presser table d is in contact with the cutter. The revolving cutter a rotates at almost the same speed as the rotating cutter a, and then when the workpiece b is sent, the rotation gradually stops, and by the time it stops, the workpiece is rubbed and the surface is browned. , processing material b
When it leaves the lower surface of the holding table d, it follows around again. For this reason, conventionally, the model material was fed into the first processed material, and the rotation of the presser table was stopped while the model material was browned, expecting that the material would be browned and unnecessary. It is necessary to continuously feed the presser table to prevent it from following around, but since there are cases where it is not possible to feed the workpiece continuously, it is inevitable that the above-mentioned defective cut products will occur frequently.

In order to eliminate this drawback, there is an idea to connect the stopper e to the holding table and fix it to the material feeding table, etc. as shown by the chain line in Fig. 4, but in that case, the side surface of the processed material b comes into contact with the stopper e. Since it is necessary to feed the material B while preventing the material from moving, there is a drawback that not only is there a limit to the cutting width of the processed material b, but also a material feeding belt cannot be used in most cases.

(Problem to be solved by the invention) The disadvantage of the prior art described in the previous section is that the mechanism that is placed on the inner periphery of the rotating cutter and holds the presser table in a fixed state with the fed workpiece is not good. It is. In view of this, the present invention provides a fixed hollow shaft that cannot be rotated in the frame of a woodworking plane cutting machine.
A cutter mounting member that rotates actively with a belt or the like is fitted onto the fixed hollow shaft to attach a planar rotating cutter, and a pressure shaft that engages with the hollow part of the hollow shaft to prevent it from rotating is passed through and pressed onto the lower end of the cutter mounting member. The idea was derived from the concept of providing a table, and this configuration attempts to solve the problem.

(Means for Solving the Problems) The purpose of the woodworking plane cutting machine of the present invention is to solve the above-mentioned problems by using the above-mentioned idea. In a woodworking plane cutting machine equipped with a plane rotating cutter that rotates in contact with the workpiece conveyed by the material conveying belt, a fixed hollow shaft fixed non-rotatably to the frame 2 on the material conveying table or the material conveying belt is used. 13, and a planar rotating cutter is attached to the fixed hollow shaft by externally fitting a cutter mounting member rotating by a belt or the like, and further engages the fixed hollow shaft in the rotational direction to enable upward movement. A compression shaft is fitted inside and is compressed from the
A presser table located on the inner periphery of the cutter is attached to the lower part of the pressure shaft, and a shaft with a reduced diameter that protrudes upward from the fixed hollow shaft is provided at the upper end of the pressure shaft.
