Abstract
The invention provides a woodworking bench saw. The woodworking bench saw comprises a working tabletop, a saw web and a motor for driving the saw web to rotate, wherein a wood plate detection device and a hand detection device are arranged on the working tabletop; the wood plate detection device and the hand detection device are connected with a relay; and the relay is connected to the motor and is used for controlling the motor to be started and stopped according to detection signals of the wood plate detection device and the hand detection device. The woodworking bench saw in the invention can detect a position of the hand and a working state of the wood plate at the same time and control the woodworking bench saw to be safely started and stopped; therefore, a phenomenon that the hand of an operator is cut by the saw web because of accidental negligence of the operator or accidental rotation of the saw web is avoided; and a protection function is effectively realized.
Description
Technical field
The present invention relates to the desktop-type powered field of tool, especially a kind of carpenter's bench saw, a kind of anti-carpenter's bench saw of cutting hand more specifically.
Background technology
Carpenter's bench saw be the desktop-type powered field of tool the most frequently used one of instrument, when bench saw was worked, its motor drove cutting saw blade and rotates at a high speed, if the carpenter is careless, can cause hand to contact with the saw blade that rotates at a high speed, saw blade will hurt even cut off finger.
Now, occur a kind of Anti-cut Gloves on the market, adopted steel loop or steel mesh formula project organization, however carpenter's inconvenience during with such gloves operation, and influence homework precision.Still more, at some saw blades that rotates at a high speed, for example in face of the alloy saw blade, the operation of Anti-cut Gloves is very little, can't play protective action effectively.
Summary of the invention
At defective and the deficiency of prior art, the present invention aims to provide a kind of anti-carpenter's bench saw of cutting hand, prevents accident carelessness or the unexpected situation that causes staff to be cut by saw blade of rotating of saw blade because of the operator, effectively plays protective action.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is as follows:
A kind of carpenter's bench saw, the motor that comprises work top, saw blade and the rotation of driving saw blade, described work top is provided with plank checkout gear and hand checkout gear, described plank checkout gear, hand checkout gear are connected with a relay, and this relay is connected to described motor and is used for controlling according to the detection signal of described plank checkout gear and hand checkout gear the start and stop of described motor.
Further, described plank checkout gear is a Sun-shading type optoelectronic switch, and is installed in the groove of work top.
Further, also be provided with a sheet glass on the described Sun-shading type optoelectronic switch and seal described groove.
Further, the upper surface of the sheet glass after the sealing and described work top are coplanar.
Further, described hand checkout gear is the normally closed correlation type infrared sensor that is arranged on the saw blade both sides, and its line is vertical with the direction of motion of plank.
Further, the setting height(from bottom) of described normally closed correlation type infrared sensor on described work top can be regulated.
Further, described Sun-shading type optoelectronic switch from the horizontal direction of saw blade distance greater than the distance of described normally closed correlation type infrared sensor from the horizontal direction of saw blade.
By above technical scheme of the present invention as can be known, beneficial effect of the present invention is the job state by the position of detecting hand simultaneously and plank, safe start and stop according to detection signal control carpenter bench saw, prevent accident carelessness or the unexpected situation that causes staff to be cut by saw blade of rotating of saw blade because of the operator, effectively play protective action.
Description of drawings
Fig. 1 is the anti-structural representation of cutting carpenter's bench saw of hand of preferred embodiment of the present invention.
Fig. 2 is that the hand among Fig. 1 embodiment detects schematic diagram.
The specific embodiment
In order more to understand technology contents of the present invention, especially exemplified by specific embodiment and cooperate appended graphic being described as follows.
Shown in Fig. 1-2, according to preferred embodiment of the present invention, carpenter's bench saw comprises work top 1, saw blade 2 and drives the motor 3 of saw blade rotation, work top 1 is provided with plank checkout gear 4 and hand checkout gear 5, plank checkout gear 4, hand checkout gear 5 and a relay 6 are connected in the circuit loop, and this relay 6 is connected to motor 3 and is used for controlling according to the detection signal of described plank checkout gear 4 and hand checkout gear 5 start and stop of described motor.
As shown in Figure 1, motor 3 be installed in work top 1 below, relay 6 also is installed in the following of work top and comparatively approaching with motor, to reduce wiring.Certainly, the motor 3 of present embodiment be one by the motor of AC-powered, realize being electrically connected by supply socket 8 and external communication electricity.
In the present embodiment, plank checkout gear 4 is a Sun-shading type optoelectronic switch, and is installed in the groove of work top 1.Like this, prevent on work top and during preparation work, plank checkout gear 4 can detect and send response signal as template.Preferably, also be provided with a sheet glass 7 on the Sun-shading type optoelectronic switch and seal described groove, prevent that so foreign material such as dust, chip from dropping in the groove, and can not influence the induction of Sun-shading type optoelectronic switch.
Further, upper surface and the described work top of the sheet glass 7 after the sealing are coplanar, to guarantee the surfacing of work top.
In the present embodiment, hand checkout gear 5 is for being arranged on the normally closed correlation type infrared sensor of saw blade both sides, and its line is vertical with the direction of motion of plank.Sun-shading type optoelectronic switch 4 from the horizontal direction of saw blade 2 distance greater than the distance of normally closed correlation type infrared sensor 5 from the horizontal direction of saw blade 2.
As shown in Figure 2, wherein label 10 is the detection line of normally closed correlation type infrared sensor 5, label 11 is the hand on the plank, label 12 is plank, in the present embodiment, the setting height(from bottom) of normally closed correlation type infrared sensor 5 satisfies its detection line 10 can detect hand on the plank 12, and detects less than plank 12.This setting height(from bottom) can be adjusted according to the practical operation needs, to adapt to the operation needs of different planks.
In the present embodiment, when plank is placed on the working face 1, shelter from Sun-shading type optoelectronic switch 4, and when normally closed correlation type infrared sensor 5 does not detect staff, relay is 6 closures, motor 3 begins to rotate, and drives saw blade 2 and start working, and so can prevent because the workman is unripe but electric saw is opened the contingency that causes.
When Sun-shading type optoelectronic switch 4 was not blocked fully, relay 6 disconnected, and motor stops operating.
When 5 couples of people's of normally closed correlation type infrared sensor the hand distance from saw blade 2 detects, less than safe distance the time, relay 6 can cut off automatically, thereby motor is quit work, with the safety operation distance of guarantor's hand.
In sum, carpenter's bench saw of the present invention by detecting hand simultaneously the position and the job state of plank, safe start and stop according to detection signal control carpenter bench saw, prevent accident carelessness or the unexpected situation that causes staff to be cut by saw blade of rotating of saw blade because of the operator, effectively play protective action.
Though the present invention discloses as above with preferred embodiment, so it is not in order to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is as the criterion when looking claims person of defining.
