Description

[Detailed description of the invention] The present invention includes a surface plate, a guide member erected on the surface plate, and an elevating section guided by the guide member so as to be movable up and down via an elevating and lowering feeding mechanism. The elevating section is brought into downward contact with the workpiece placed on the surface plate, and the workpiece is brought into contact with the workpiece by a feed roller and plane barrel that are pivotally supported at the lower part of the elevator and driven and rotated by a motor. The present invention relates to a cutting waste discharging device for an automatic plane machine that cuts while being conveyed in a direction. Conventionally, as a cutting waste discharge device for an electric plane, the device disclosed in Japanese Utility Model Publication No. 38-12997 is known.

The cutting waste discharge device disclosed in the above-mentioned Japanese Utility Model Publication No. 38-12997 has a ventilation hole drilled in the circumferential surface covering a fan attached to the shaft of the electric motor and an exhaust port opening on the side of the electric motor. A cylindrical casing with a closed lid is attached to the back of the motor, and one end of the air guide tube is attached in the tangential direction of the casing with the air guide tube communicating with the above-mentioned ventilation hole, and the other end of the air guide tube is cut by cutting the cutter block cover. It has an opening in the side wall opposite to the waste outlet.

However, according to the conventional device described above, although one end of the air guide tube is installed in the connection direction of the casing, the shape of the air passage for guiding the cooling air from the intake hole to the cutting waste outlet is approximately U-shaped in plan view. The cooling air is directed in a direction perpendicular to the direction of rotation of the cutter block, which means that the cooling air collides with the side wall of the cutter, resulting in large airflow resistance, which may reduce the efficiency of removing cutting chips or cause strong winds. There is a drawback that it requires

The present invention is an attempt to solve the above-mentioned conventional drawbacks, and the planer body and the feed roller, which are driven and rotated by a motor installed in the lifting part, are pivotally supported at the lower part of the lifting part facing the top surface of the surface plate.

By threading the threaded portions 22a and 22'a of 2' together, the elevating portion 3 is supported by the elevating and lowering feed mechanism 4 and guided up and down by the guide member 2.

Moreover, the above-mentioned elevating and lowering feed mechanism 4 has left and right feed screw shafts 2.
2, 22', a handle shaft 23, and a gear transmission mechanism 24. That is, the feed screw shafts 22, 22' are connected to the left and right guides 2a, 2a with their upper and lower ends connected to the center inside the left and right guides 2a, 2a of the guide member 2 via a holder 25 and a set plate (not shown). The holders 25, 25 are rotatably installed at the upper and lower ends of the holders 25, 25 with bolts 26, and between the two feed screw shafts 22, 22'.
The gear transmission mechanism 24 is interlocked with the hand shaft 23 rotatably installed on the handle shaft 23 by the gear transmission mechanisms 24, 24, and the handle shaft 23 is rotated by the handle 28 fixed to the protruding end of the handle shaft 23. The left and right feed screw shafts 22, 22' are rotated through the shafts to move the elevating section 3 up and down. In FIG. 2, reference numeral 26 indicates a spring that urges the elevating section 3 upward.

In the above configuration, when cutting a material to be cut using this, the material to be cut W is placed on the surface plate 1 and the roller 8 in front of the surface plate 1, and the motor 15 is is started to drive and rotate the plane barrel 13 and feed rollers 14, 14'.

Next, depending on the thickness of the workpiece W, the elevating part 3 is
When the machine body 13 and the feed rollers 14, 14' are lowered by the elevating feed mechanism 4 and brought into contact with the upper surface of the workpiece W as shown in FIG. While being conveyed on the surface plate 1 to the right in the figure, it is cut by the plane barrel 13.

At this time, cutting waste is generated, and the cutting waste is scattered from the cavity 17 into the discharge port 20 in the rotational direction of the plane barrel 13, that is, in the counterclockwise direction in FIG. , the cooling air from the motor 15 is blown in from the discharge port 21 that opens upward in the inner part and is discharged to the outside, and the cutting chips are caught up in this cooling wind and discharged to the outside from the discharge port 20, so that the air Cutting debris will not clog inside the body 17 or the discharge port 20.

After cutting one side of the workpiece W in this way, return the workpiece W, turn it over so that the other side faces upward, and feed it onto the surface plate 1 in the same manner as described above. It can be cut by cutting.

As described above, according to the cutting waste discharging device for an automatic planer according to the present invention, the elevating section 3 having the planer body 13 driven and rotated by the motor 15 and the feed rollers 14, 14' is mounted on the surface plate 1. In an automatic plane machine that is provided to move up and down by a lifting mechanism, a hollow part 17 is provided vertically through the roller case 12 of the lifting part 3, and a planer body 1 is installed in the hollow part 17.
3 is pivotally supported, the upper part of the cavity 17 is covered with a dust cover 18, and the cutting waste discharge port 20 is opened in the side of the roller case 12, and parallel to the length direction of the plane body 13. The motor cooling air outlet 21 is provided long and parallel to the length direction of the plane body 13 by communicating with the upper inner part of the cutting waste outlet 20 to direct the motor cooling air in the direction of rotation of the plane body 13. Since the motor cooling air is configured to be discharged through the exhaust port 21, the cutting waste is discharged from the cutting waste discharge port 20.
Since the cutting chips are discharged along the entire length of the plane body 13 in the direction of rotation, the cutting chips are directly exposed to the cooling air and engulfed in a dispersed state, unlike conventional methods. Compared to the example in which the cooling air is discharged in the axial direction of the plane body, cutting chips are concentrated and discharged.
The efficiency of removing cuttings from the motor 1 is much improved, and there is no need to install a special fan on the motor shaft for removing cuttings in order to obtain strong wind.
Since the cutting waste can be efficiently discharged by relatively weak cooling air blown by the motor cooling fan provided in the motor cooling fan 5 itself, there is no possibility of defective removal of cutting waste, and the cutting process is improved. Not only can workability be improved, but clogging with cutting debris can be prevented, thereby providing a good cutting surface for the workpiece W. Moreover, simply providing the dust cover 18 above the cavity 17 in the roller case 12 Since it is structurally extremely simple, it can be manufactured at low cost.
