[Detailed description of the invention]

[0001]

INVENTION The present invention relates, in wood processing machine having a cutting blade on the table top, resulting in cutting of the workpiece
And a device for removing chips, dust and dust .

[0002]

2. Description of the Related Art Conventionally, in wood processing machines, wood is cut.
Dust removal to remove chips, dust, dust, etc. generated in
Some have a built-in fan and blower. This is
It operated in synchronization with power start and stop. Ma
Also, a wood processing machine that does not have a dust collection function or a ventilation function
Install a dust collector or blower separately from the main unit,
Activated separately from the power supply of the body, with the power of the dust collector and blower,
The suspension was being performed.

[0003]

[Problem to be solved by the invention] In the former case, dust collection
And the start and stop of the blower are synchronized with the power of the main unit.
Therefore, after stopping the cutting power of the machine,
And the blower are also stopped at the same time. For this reason, cutting power
After stopping, chips generated by coasting rotation are not completely removed,
It was deposited on the table surface and cutting blade. Piled chips
And leave it on the table with wet chips.
The surface and the knife will rust. Therefore, the cutting work is completed
Later, using brush or cloth, etc., artificially around the blade,
Dust and chips were removed. Artificial chip removal work
The work around the blade involves dangers such as injuries.
The cutting efficiency was significantly reduced. In the latter case, the body
Start of dust collection device and blower at the start of cutting work
And after some time after the end of the cutting operation,
Completely removes chips generated by rolling from the table surface and cutting tool
Check that the dust collection device and blower have been stopped.
I was For this reason, as in the former,
Problem. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide an apparatus for reliably removing chips without lowering a cutting operation efficiency.

[0004]

The device according to the present invention comprises a tape
Feeder having a cutting blade on the upper surface and facing the table
In a wood processing machine having a device,
Detection of wood in front of the cutting tool on the wood feed side of the lumber equipment
Detector, and an air path to the cutting tool and its surroundings
An air outlet is provided, and a blower that blows air to the air path is placed on a table.
And the detector has detected wood "Yes"
In response to the signal, the blower is driven, and the detector is wood “Nothing”
Control circuit that stops after a certain period of time upon receiving a signal
A road is provided .

[0005]

In the apparatus constructed as described above, wood is supplied by a feeding device to a working gap between the feeding device and a table having a cutting blade to perform a cutting operation. At this time, a detector provided in front of the cutting blade of the table detects the wood, and a timer circuit is operated by this detection signal to automatically drive the blower. After the wood passes the detector, the timer circuit stops after a preset time has elapsed, and stops the blower. Wherein the detector, the timer circuit automatically drives the blower, and makes it possible to chip removal operation not to lower the more work <br/> efficiency to stop.

[0006]

FIG. 1 shows an embodiment of the apparatus according to the present invention.
This will be described with reference to FIG. In the figure, 1 is the base,
As shown in FIG. 1, a table 2 is provided on the upper part of the table 2. A circular turntable 3 is fitted and provided in the center of the table 2, and a cutting tool 4 is embedded in the turntable 3, An air passage is formed around the table 4 and its surroundings, an outlet 5 is provided on the table 2, and
A detector 7 for detecting the passage of wood 6 is provided in front of the cutting blade 4 on the feeding side of the cutting tool 4. The column 8 stands on one side of the table 2 and supports a head 9 facing the table 2 so as to be able to move up and down. A pair of rollers 10 and 11 are pivotally supported before and after the head 9, an endless feed belt 12 is stretched over the rollers 10 and 11, and the feed belt 12 is rotated by a feed motor 13. The screw type automatic feeder 14 linked to the head 9 is rotated by a lifting / lowering motor 15 to adjust a processing interval between the material feeding belt 12 and the table 2. A blower 16 for blowing air to the outlet 5 is provided on the table 2, and the blower 16 is started and stopped by a timer circuit 17 serving as a control circuit . The timer circuit 17 detects the ON signal of the detector 7 ,
6 Start by detecting “Yes”, and after detecting the passage of wood 6, a detection signal from ON to OFF,
By detecting the material 6 "absence" , the blower 16 is stopped after a preset time. In the present embodiment, the preset time is set to the time until the end of the wood 6 passes from the detector 7 to the cutting blade 4 . The same effect can be obtained by starting and stopping the blower 16 by receiving the detection signal of the detector 7 by a microcomputer and by using the microcomputer. In the above configuration, the elevating motor 15 is driven by an elevating operation switch (not shown), and the feeding belt 12 and the table 2 are moved.
Is adjusted in accordance with the height of the wood 6 to be fed. Next, the feed motor 13 is driven by an operation switch (not shown) to rotate the feed belt 12. In this state, when the wood 6 is supplied to the processing interval between the feeding belt 12 and the table 2, the wood 6 is turned off by the detector 7 provided in front of the cutting blade 4.
The timer circuit 17 is driven by the detection signal of N, and the blowing device 16 is started to blow air around the cutting blade 4 to remove dust, dust, and chips around the cutting blade 4. Further, it is detected that the wood 6 is further fed by the feeding belt 12.
The wood 6 comes off from the output device 7 , and the detector 7 turns on and off
Is output and input to the timer circuit 17. The timer circuit 17 receives the detection signal and stops after a time period from when the end of the wood 6 passes through the cutting blade 4 from the detector 7 to the end, and the blower 16 stops. Therefore, before cutting,
After the cutting, dust, dust and chips around the cutting blade 4 are automatically removed. In the present embodiment, the blower
The detector 16 is activated by the detector 7 provided in the table 2.
However, the detector 7 is located in front of the feeding belt 12 in the feeding direction.
The same effect can be obtained by providing the other head 9. As an application example of the present embodiment, in a case where the material feeding motor 13 of the wood 6 automatically stops driving, the same effect can be obtained even if the blowing device 16 is synchronized with the material feeding motor 13.

[0007]

According to the present invention, the detector is made of wood.
The blower is driven in response to the signal that detected
After a certain period of time after the output unit receives the signal that wood was detected
The control circuit that stops the air blower generates
Since the swarf chips are completely removed, artificial chip removal
Work is unnecessary, and labor is saved and work efficiency is improved.
Can be. Also, a table with garbage, dust, and chips
The life of the cutting tool to prevent rust on the surface and the cutting tool
Which has a remarkable effect on the improvement of cutting finish
It is.
