Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a dust collector that automatically sucks and collects cutting dust during cutting of wood, resin materials, etc. while cutting.

[Conventional technology]

Figures 4 to 8 show a conventional device, with Figure 4 being a front view of the cutting machine head, and Figure 5 being a side view showing the state in which the cutting direction has been changed by 90 degrees and it is turned sideways. Show, 6th
The figure, FIGS. 7 and 8 are examples showing the current dust collection method during cutting.

In the figure, 1 is a spindle unit, and 5 is a housing that holds this spindle unit 1, and has a degree of freedom in selecting the cutting angle. 8 is a cutting cutter, 9 is a chuck for attaching this cutting cutter 8 to the spindle unit 1, IO is a mechanical device main body, 11 is a dust collector, 12 is a suction device and a hose, 13 is a suction device having a dust collection hood, 14 15 is the object to be cut, and 15 is the cutting dust.

Next, the operation will be explained. Cutting cutter 8 is chuck 9
The cutting force is applied to the spindle unit 1 via the rotational force of the spindle head 1.
Cutting is performed on the object to be cut 14 based on the instructed procedure.

However, due to differences in cutting conditions, cutting dust 15 such as coarse chips or fine dust is generated. This cutting powder 11115
Regarding processing, it is common practice for workers to manually clean after the cutting process is completed, but especially fine dust becomes floating dust and seriously impairs the environment of the machine installation room, so , a manual dust collection method using a dust collector 11, a suction device and a hose 12, or a seventh method.
As shown in FIGS. 8 and 8, a dust collection system is used in which a dust collection hood 13 is provided so as not to interfere with the operating area of a cutting machine head comprising a spindle unit 1 and a cutting cutter 8. In addition, 14 in Fig. 8 is a suction outlet,
15 is a suction hose connected to the dust collector.

[Problem to be solved by the invention]

Since the conventional dust collector is configured as described above, it is necessary to manually make the suction device and the hose 12 follow the trajectory of the cutting cutter 8, and unless you are familiar with the cutting work program, the suction device and There was a safety problem in that the operator had to be careful not only about the hose 12 but also about interference between himself and the machine.

Although the dust collection hood 13 can be installed automatically, it must have a structure that does not interfere with the operating angle determined by the selection of the cutting head posture, and must be designed so that it does not interfere with the operating angle determined by the selection of the cutting head posture. Dust collector 1 with a long distance and a large processing air volume! At the same time as it becomes necessary,
Due to its structure, there is a high risk of interference with the object to be cut 14, especially during cutting of the side surface, and if we try to remove the risk further, the dust collection efficiency will drop significantly, causing problems such as not being able to achieve the initial purpose. .

This invention was made to solve the above-mentioned problems, and provides a dust collector in a cutting machine head that can operate automatically, has little interference with the object to be cut, and can collect dust effectively. The purpose is to

[Means to solve the problem]

The dust collector according to the present invention includes a dust collector main body having a dust suction outlet in a cutting head portion, and a dust collector body connected to the main body,
Arranged to contain dust around the cutting cutter,
It is equipped with a dust collection hood made of flexible material.

[Effect]

In this invention, by installing the dust collector near the cutting cutter section, that is, the source of cutting dust, automatic operation is possible, and the maximum dust collection effect can be achieved with a compact and minimum dust collector capacity. In addition, the dust collection hood, which is made of nylon brushes that are softer than the object to be cut, is connected to the main body of the dust collector to prevent interference with the object to be cut.
By ensuring sealing performance, dust collection efficiency is improved.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram of a cutting machine head according to an embodiment of the present invention, FIG. 2 is an enlarged sectional view of the main parts, and FIG. 3 is a schematic diagram of the entire machine. Note that the same or equivalent parts as in FIGS. 4 to 8 above are given the same reference numerals.

In the figure, 2 is the dust collector body attached to the tip of the spindle unit 1, 3 is the suction outlet provided in a part of it, 4 is the suction hose, and 6 is the bolt attached to the tip of the dust collector body 2. 7, and is a dust collection hood made of nylon brushes or the like attached around the cutting cutter 8 in consideration of interference with the object to be cut.

Next, the effect will be explained. The object to be cut 14 is cut by the cutting cutter 8, and the cutting dust 15 generated at this time is contained in the dust collection hood 6 to prevent it from scattering to the outside, and is also sucked as the dust collector 11 operates. The dust is sucked in from the outlet 3 and passes through the suction hose 4 to the dust collector 11.
is discharged.

Also, when cutting the side surface of the object to be cut 14, the dust collector main body 2 and the dust collecting hood 6 operate together with the spindle unit 1 and the cutting cutter 8, so the S dust procedure is the same as described above.

Furthermore, even if the cutting surface of the cutting object 14 has a curved surface shape, by using a material such as a nylon brush for the material of the dust collecting hood 6 that is softer than the cutting object, interference with the cutting object can be suppressed and the curved surface shape can be suppressed. By deforming the brush along the curve, it achieves a high dust collection effect on floating dust that can significantly impair environmental conditions while ensuring a sealing effect.

〔Effect of the invention〕

As described above, according to the present invention, the dust collector is attached to the cutting cutter, that is, near the source of cutting dust, and the dust collection hood is made of a flexible material such as a nylon brush. The device can be made compact and inexpensive, and has high dust collection efficiency. Furthermore, since automatic operation is possible, it has the effect of saving labor, especially in the processing of resin materials that are at risk of dust explosions.
