Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a remote control device of a dust collector connected by a hose extending from a dust discharge port of a hand-held power tool for cutting, grinding, cutting, and the like to a dust collector.
[0002]
[Prior art]
A conventional technique will be described with reference to FIGS. The dust collector 4, which combines a hand-held power tool that cuts, grinds, cuts, and the like the work material 12 with the dust collector 4, and collects and transports dust discharged from the power tool, is roughly divided into two types. is there.
[0003]
The first method is one of a hand-held power tool from a dust collector 4 incorporating a motor (not shown) and a dust collecting fan in a state where the work 12 is cut in the direction of the arrow shown in FIG. A hose 7 is connected to the cutting powder discharge port 6 of the circular saw 5, and each power cord 8 is connected to a main power supply. Therefore, each of the circular saw 5 and the dust collector 4 has a start / stop switch. First, a start / stop switch (not shown) of the dust collector 4 is turned on, and a suction force is generated in the hose 7 via a motor and a dust collecting fan. Next, it is moved to the circular saw 5, which is one of the electric tools, and the start / stop switch is turned on to make the circular saw 5 ready for cutting work. Next, when the cutting operation of the work material 12 is started by turning the circular saw 5 in the direction of the arrow, the cutting powder by cutting is conveyed into the dust collector 4 through the hose 7 from the cutting powder discharge port 6 of the circular saw 5 by suction. Dust is collected. When the cutting operation is completed, the start / stop switch of the circular saw 5 is turned off and the switch is moved to turn off the start / stop switch of the dust collector 4. The length of the hose 7 varies depending on the work content, but is generally 5 m to 10 m. Therefore, according to the above-mentioned work, it reciprocates between 5 m and 10 m each time the work starts and ends. After the cutting operation, the start / stop switch of only the circular saw 5 may be turned off. However, continuous operation of the dust collector is a problem due to noise regulations and work environment problems. It is not preferable from the viewpoint of energy saving.
[0004]
The second method is the method shown in FIG. The dust collector 4 includes a motor that rotates a dust collector fan (not shown), an outlet 18 for connecting a power tool, an interlocking device that detects a current value of the outlet 18 and starts and stops the motor. It is connected to the. When the power cord 8 of the power tool is connected to the outlet 18, the power of the power tool and the dust collector 4 is supplied from one power cord 8 of the dust collector 4. When the circular saw 5, which is one of the electric tools, is started, the motor of the dust collector 4 rotates via the interlocking device. With the suction force generated by the rotation of the dust collecting fan by the motor, the dust discharged from the power tool is collected or conveyed into the dust collector 4 through the hose 7. When the circular saw 5, which is one of the power tools, is stopped, the motor of the dust collector 4 is stopped via the interlocking device. Since the dust collector 4 is often used at a construction work site, a power supply of 100 V is generally used. Therefore, as described above, power is supplied from the single power cord 8 of the dust collector 4, so that the electric capacity of either the dust collector 4 or the power tool to be connected is regulated. The general dust collector 4 has a motor capacity of about 10A to 12A due to a problem of required suction force. Therefore, since the capacity of the power cord 8 and the plug is 15 A at 100 V, the capacity of the power tool which can be necessarily connected is 3 A to 5 A. However, in reality, when limited to power tools that can be used for business purposes, power tools with a capacity of 3 A to 5 A have low power and cannot be used. Most electric tools actually used for business use are 7A to 12A. Therefore, the second system is difficult to use for business use.
[0005]
[Problems to be solved by the invention]
As described above, in the first method, the electric capacity of the power tool to be used is not regulated within 15 A, but the power tool and the start / stop switch of the dust collector must be operated each time. In addition, every time it starts and stops, it has to reciprocate between 5 m and 10 m apart, and there has been a problem that the work efficiency is significantly reduced.
[0006]
In the second method, the power tool and the dust collector operate by operating the start / stop switch of the power tool. However, since power is supplied from one power cord of the dust collector, the electric power of the power tool to be connected is electrically controlled. There is a problem that the capacity is restricted and cannot be used for business use.
[0007]
An object of the present invention is to solve the above problems, to provide a dust collector combined with a power tool that can use a power tool having a high working efficiency and a large electric capacity, and specifically using a power tool. An object of the present invention is to easily start and stop the power tool and the dust collector without moving from the place where the power tool is located, eliminate the restriction on electric capacity of the power tool to be used, improve work efficiency and improve the work environment.
[0008]
[Means for Solving the Problems]
The above object is achieved by connecting the respective power cords of the power tool and the dust collector to different power supplies, transmitting a signal to the remote control transmitter, performing signal processing from the remote control transmitter, and starting the motor of the dust collector via the driving device. Achieved by arranging a remote control receiver for instructing a stop in a proper position of the dust collector.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The dust collector in the present embodiment will be described with reference to FIGS. FIG. 1 is an external perspective view showing a state where a dust collector and a circular saw, which is one of electric tools, in the present embodiment are combined and performing a cutting operation, FIG. 2 is a front view including a partial cross section of the dust collector, and FIG. 2 is a side view, FIG. 4 is a block diagram, and FIG. 5 is a configuration diagram showing a remote control transmitter. 1 to 5, a hose 7 is connected from a dust collector 4 containing a motor 1, a dust collecting fan 2 and a dust collecting tank 3 to a cutting powder discharging portion 6 of a circular saw 5, which is one of hand-held power tools. I have. Each power cord 8 is connected to a main power supply. A remote control transmitter 9 for transmitting signals and a remote control receiver 10 for performing signal processing from the remote control transmitter 9 and for starting / stopping the motor 1 via a drive unit 17 (not shown) are arranged in the head unit 11. I do.
[0010]
In the above configuration, when the switch of the circular saw 5 (not shown) is turned on, the circular saw 5 starts. When the remote control transmitter 9 is operated at that location, a signal is received by the remote control receiver 10 disposed on the head unit 11 of the dust collector 4 at a distance of 5 m to 10 m, and the motor 1 and the dust collection are received via a driving device 17 (not shown). The fan 2 rotates, and a suction force is generated in the hose 7. When the circular saw 5 is moved on the work material 12 in the direction of the arrow to start the cutting operation, the cutting powder generated by the cutting is conveyed into the dust collecting tank 3 of the dust collector 4 by the suction force in the hose 7. This cutting operation is repeated, and after the operation is completed, a switch (not shown) is turned off to stop the circular saw 5. Next, the remote control transmitter 9 is operated from the position of the circular saw 5 and the remote control receiver 10 5 m to 10 m away receives the signal. The motor 1 of the dust collector 4 and the dust collection fan 2 are stopped via the driving device 17 and the hose is stopped. The suction force in 7 disappears. As described above, since the dust collector 4 and the circular saw 5 are connected to the main power supply from the respective power cords 8, the electric capacity is not restricted within 15 A, and the position of the circular saw 5 is 5 m to 10 m away from the dust collector 4. By operating the remote control transmitter 9, the dust collector 4 can be started and stopped, so that the dust collector 4 does not need to go back and forth 5 m to 10 m every time the dust collector 4 is started and stopped. The work efficiency can be greatly improved, and the dust collector 4 can be started and stopped at any time in accordance with the start and stop of the circular saw 5, so that the effect of improving the working environment such as noise can be obtained.
[0011]
Further, a changeover switch 13 for switching a means for starting and stopping the motor 1 of the dust collector 4 is disposed in the head unit 11. When the remote control receiver 10 that receives the signal from the remote control transmitter 9 and the remote control system for starting and stopping the motor 1 via the driving device 17 and the switch 13 are switched, the power supplied from the power cord 8 is directly The power supply is switched to a power switch method that starts / stops the motor 1 by turning on / off. As described above, two types of the motor 1 are used as the start / stop means.
[0012]
In the above configuration, if the changeover switch 13 is switched to a remote control system, the operation and operation by the remote control transmitter 9 described above can be performed. On the other hand, if the changeover switch 13 is switched to a power switch system, the power switch is turned on / off, and the motor 1 and the dust collection fan 2 of the dust collector 4 start and stop. Therefore, it can be conveniently selected according to the work content and preference.
[0013]
In addition, since the hook shape 14 is formed at an appropriate position of the remote control transmitter 9 for transmitting a signal, the remote control transmitter 9 can be hooked on a worker's chest pocket or a belt or the like, thereby preventing loss and improving workability. Can be measured. Further, if the hook shape 14 is made of a material having high elasticity, for example, a spring steel, it becomes difficult to come off easily, which is convenient.
[0014]
In addition, since the storage portion or the locking portion 15 of the remote control receiver 10 for receiving a signal is provided at the position of the head portion 11 where the motor 1 and the like of the dust collector 4 are arranged, it is convenient for storage, transportation, storage and the like. It also helps prevent loss.
[0015]
In addition, the concave and convex shape 16 is formed in an appropriate place of the storage portion or the locking portion 15 of the remote control transmitter 9, and the concave and convex shape 16 is formed on the exterior portion of the remote control transmitter 9 so as to fit therein. When not, it can be locked to the head 11 of the dust collector 4. In addition, there is no fear that the dust collector 4 may come off or fall due to vibrations during transportation or movement, which is convenient. By forming the concavo-convex shape 16 in the middle of the side surface of the remote control transmitter 9, the insertion direction of the remote control transmitter 9 can be given. By setting the direction so that the transmission switch operation surface of the remote control transmitter 9 is on the front side, the dust collector 4 can be started and stopped by the remote control transmitter 9 even in the housed and locked state.
[0016]
Although the circular saw 5 has been described as an example of the power tool, any power tool other than the circular saw may be used as long as the power tool involves dust or the like.
