Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting machine having a blade unit such as an electric saw which moves along a cutting direction.
The present invention relates to a dust collector in a cutting machine for sucking dust that scatters during cutting.

[0002]

2. Description of the Related Art Generally, when an object to be cut is cut with an electric saw or the like, dust is generated on the object to be cut and scattered.
The cutting machine is provided with a dust collecting device in order to prevent the worker from being affected by the dust and to prevent the periphery of the cutting machine from being contaminated by the dust.

By the way, when cutting an object to be cut by an electric saw, the object to be cut is moved with respect to the fixed electric saw, or conversely, the object is fixed and the electric saw is moved. Become. Then, when trying to collect the dust, if the electric saw is fixed, a cover that covers a part of the blade of the electric saw is provided at the place where the dust is scattered, and the dust is collected at that portion. There was a suction port for collecting dust. When moving the electric saw, a cover that covers a part of the blade of the electric saw is attached so as to move along with the electric saw, and the suction port of the dust collector is connected to this cover to collect dust. Was being done.

By the way, when the electric saw is fixed,
Since the scattering direction of dust is relatively stable, it is possible to collect dust relatively easily. However, when moving the electric saw, the scattering direction of dust is unstable,
Also, because of the positional relationship between the object to be cut and the blade of the electric saw, it is difficult to provide the cover in accordance with the dust scattering direction.
Even a powerful dust collector cannot collect a large amount of dust, and particularly if the cutting distance is long, a considerable amount of dust will be scattered.

As described above, since it is difficult to collect almost all of the dust generated by just covering a part of the blade of the electric saw, when it is desired to completely prevent the dust from scattering,
A cover was provided to cover the entire moving range of the electric saw, and the dust collector was connected to this cover.

[0006]

By the way, if the entire moving range of the electric saw is covered with the cover and the dust collecting device is attached to the cover as described above, dust will not be scattered around, but It is difficult to collect all the dust generated in the cover by the dust device, and a considerable amount of the dust that cannot be collected is dropped and accumulated on the floor inside the cover. Therefore, the inside of the cover must be cleaned regularly. In addition, dust may be scattered outside the cover during cleaning.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent dust from being scattered around the cutting machine, and to remove dust accumulated periodically. An object of the present invention is to provide a dust collecting device for a cutting machine that does not require.

[0008]

The dust collecting device in the cutting machine of the present invention moves while moving in the cutting direction of the object to be cut.
By enclosing the entire movement range from the movement start point to the movement end point of the blade unit for cutting the cut object, the entire movement range is cut.
A box body for partitioning the body from the outside, a blower means for blowing air into the box body, and a dust collecting means for sucking dust in the box body , wherein the box body is a blade unit of the blade unit. An outlet for blowing out the air from the blower means is provided near either the movement start point or the movement end point .
In addition, the suction means for sucking dust by the dust collecting means is provided in the vicinity of either the movement start point or the movement end point of the blade unit and the other means.

[0009]

[Function] The box body moves from the movement start point of the blade unit to the movement end point.
By enclosing the entire range of movement in
Since it is divided from the part, dust will not be scattered outside the box. Then, since dust can be sucked while blowing air by the air blowing means, the dust is blown up by the blown air and the rate of dropping and depositing is low, and dust is sucked by the dust collecting means.

Further, the dust once dropped is re-raised by the air flow generated by the air blowing means and the dust collecting means inside the box body, so that the possibility of being accumulated inside the box body is low.
Also, air is the starting point of movement of the blade unit or
From one end of the movement to the other end
It is unlikely that there will be a drift around the blade of the blade unit. Further, the dust generated around the blade during cutting is immediately blown off by the air and scattered toward the suction port, which is likely to be sucked from the suction port.

Next, the dust collector in the cutting machine of this embodiment will be described. As shown in FIG. 1, the dust collector includes a box body 10 for covering the sizer device, a dust collecting means (not shown) connected to the box body 10, and a box body 10 similarly connected to the box body 10. It is configured mainly with a blower (not shown) provided.

The box body 10 is formed in a rectangular parallelepiped having a rectangular shape in a side view with the moving direction of the blade unit 3 as a longitudinal direction. Then, in the box body 10, the blade unit 3
An outlet 11 for connecting a blower is provided on the bottom surface near the movement starting point a. A flexible tube 12 is connected to the air outlet 11 for supplying air from a blower to the portion of the air outlet 11 outside the box body 10. Further, as shown in FIG. 1, the air outlet 11 is provided near the left side surface of the box body 10 in the drawing.
The air blown out of the box collides with the side surface of the box, the ceiling, etc. and flows to the left in the figure . That is, the air outlet 11 is provided so as to blow out the air indirectly along the cutting direction.

Further, in addition to the flexible tube 12, two tubes 13 for blowing air, which are thinner than the flexible tube 12, are connected to the blowing means, and the tube 13 connects the box body 10. The endless belt 4 that penetrates and has its end 13a inside the box 10
It is arranged at two locations near b. Further, the end portion 13a of the tube 13 is arranged so as to blow air from the side of the endless belt 4b along a groove forming irregularities on the inner peripheral surface of the endless belt 4b.

On the other hand, a suction port 14 connected to the dust collecting means is provided on the bottom surface near the movement end point b. A flexible tube 15 connected to a dust collecting means is connected to the suction port 14. In addition, the box body 10 is provided with an opening (not shown) for loading and unloading the wood panel on the side surface facing the workbench 1. A curtain (not shown) made of vinyl is hung from the side surface above the opening so as to prevent dust from scattering to the outside.

The blower means is a well-known air compressor, and the air compressor and the air outlet 11 of the box 10 are connected by a flexible tube 12. The dust collecting means is a well-known dust collector, which sucks air through a filter by a suction fan, and the dust collector and the suction port 14 of the box 10 are connected by a flexible tube 15.

The operation and use of the dust collector in the above cutting machine will be described. First, the wood panel is accurately fixed to the workbench 1 of the sizer device A. And
Before operating the sizer device A, the dust collecting means and the air blowing means are operated. As a result, air is mainly blown out from the air outlet 11, the air collides with the side wall of the box 10 on the side of the movement starting point a and the ceiling, and the moving direction of the blade unit 3 toward the suction port 14 (the air flow along the cutting direction ( (Indicated by an arrow in FIG. 1) occurs.

Next, the sizer A is operated to rotate the blade 3a of the blade unit 3 and move the blade unit 3 from the movement start point a to the movement end point b. Then, the blade 3a cuts an extra face plate of the wood panel. At this time, since the air sent out from the air outlet 11 flows along the cutting direction as described above, the air flows along both side surfaces of the blade 3a, and the air is blown by the blade 3a. No dust is generated, and dust generated at the contact point between the blade 3a and the wood panel is blown toward the suction port 14.

Most of the dust is blown to the side of the suction port 14 and collected from the suction port 14, and the remaining dust rides on the air flow in the box 10 and scatters in the box 10. As a matter of fact, dust is gradually collected from the suction port 14 while flying in the box 10. In addition, dust that has fallen before being collected is also blown up again by the air flow in the box body 10,
Eventually, it will be sucked from the suction port 14.

After the cutting is completed, most dust can be collected by operating the dust collecting means and the blowing means for a while. Further, the tube 13 having the end portion 13a arranged in the vicinity of the endless belt 4b blows air to the groove forming the unevenness of the inner peripheral surface of the endless belt 4b, which is likely to be a drift, so that the endless belt 4b is cut during cutting. Dust will not collect in the groove.

As described above, according to the dust collector of the cutting machine of this embodiment, the box body 10 is the starting point of the movement of the blade unit 3 .
By enclosing the entire movement range from a to the movement end point b
Since the entire moving range is partitioned from the outside, dust is not scattered outside, and most of the dust is blown toward the suction port 14 by the air blown along the cutting direction, Since dust is sucked from the suction port 14, dust is not accumulated in the box body 10.

Further, the remaining dust particles are also blown up by the air flow generated in the box body 10, and finally the suction port 1
Dust can be collected from 4. Therefore, the worker will not be injured by the dust without wearing a dust mask or the like. Further, it is not necessary to perform a work for periodically removing dust accumulated around the sizer device A.

Further, like the groove on the inner peripheral surface of the endless belt 4b, the end portion 13a of the tube 13 for blowing out the air from the blowing means is placed at a place where the air is blown by the structure inside the box body 10 or the like. By arranging them, dust is not accumulated in the drift, almost all dust can be sucked, and cleaning is almost unnecessary.

The dust collecting device in the cutting machine of the present invention is not limited to this embodiment, but the shape of each member,
Specific structural requirements such as dimensions can be appropriately changed in implementation. For example, the air outlet 11 may be provided not on the bottom surface of the box body 10 but on the side surface of the box body 10 in the cutting direction so as to blow out the air directly in the cutting direction. Further, the number of the air outlet 11 and the number of the suction port 14 are not limited to one, and a plurality of each may be provided.

Further, in this embodiment, the tube 13 is
Although only two are provided near the endless belt, one or three or more may be provided. Also, the tube 13
The end portion 13a of the end of the blowout port 11 except the vicinity of the endless belt 4b.
In a place where it looks like a shadow from the side, it becomes a drift,
It may be placed toward a place where dust may be accumulated. Further, in the present embodiment, the cutting machine is the sizer device A, but it goes without saying that it can be applied to other cutting machines.
