Abstract
The utility model discloses a safety protective device of a sawing machine. The safety protective device of the sawing machine is capable of protecting the safety of operators entering a main machine area. The safety protective device of the sawing machine comprises a sawing machine main machine M and a programmable controller, wherein the sawing machine main machine M is connected with a power supply through a fuse, a motor controller, a first main machine power controlling connecting point J-1 and a second main machine power controlling connecting point J-2 are connected between the fuse and the sawing machine main machine M in series, and a door-opening request button is connected with the programmable controller. The output of the programmable controller respectively controls the motor controller, a safety door switch and an indicating light, a safety relay unit is connected with the safety door switch, the output of the safety relay unit controls the first main machine power controlling connecting point J-1 and the second main machine power controlling connecting point J-2, and a scram button and a return button are further connected with the safety relay unit.
Description
Technical field
The utility model relates to a kind of sawing machine safety device, especially a kind of sawing machine safety device that enters main frame region operation personal security of protecting.
Background technology
Sawing machine has saw, high speed band saw etc., normally by sawing machine main frame (motor) the band Moving plate saw or the band saw high speed operation that join by fuse and power supply.At present, around sawing machine, safety device is not set, to such an extent as to enter the operating personnel in main frame zone, because of the main frame of working security incident occurs sometimes.For Accident prevention occurs, the operating personnel that have are when entering the main frame zone, and no matter whether main frame is in running order, and it is shut down, and use state and life-span of equipment all impacted.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical problem of prior art, a kind of sawing machine safety device that enters main frame region operation personal security of protecting to be provided.
Technical solution of the present utility model is: a kind of sawing machine safety device, the sawing machine main frame M that joins by fuse and power supply is arranged, between described fuse and sawing machine main frame M, be serially connected with electric machine controller, the first host power supply control contact J-1 and the second host power supply control contact J-2; Be provided with programmable controller, be connected to the request button that opens the door with programmable controller, electric machine controller, safety door switch and indicator lamp are controlled respectively in the output of programmable controller, be connected to the safety relay unit with safety door switch, the first host power supply control contact J-1 and the second host power supply control contact J-2 are controlled in the output of safety relay unit, also are connected to scram button and SR with the safety relay unit.
The utility model enters under the prerequisite of main frame region operation personal security in protection; dump in the time of can preventing often with host work; avoid use state and the life-span of equipment are impacted, adopt simultaneously the modes such as hand-reset and indicator lamp demonstration, more strengthened the security of equipment.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: same as the prior art, the sawing machine main frame M that joins by fuse and power supply is arranged, and the prior art difference is to be serially connected with electric machine controller, the first host power supply control contact J-1 and the second host power supply control contact J-2 between described fuse and sawing machine main frame M; Be provided with programmable controller, be connected to the request button that opens the door with programmable controller, electric machine controller, safety door switch and indicator lamp are controlled respectively in the output of programmable controller, be connected to safety relay unit (G9SA-301) with safety door switch, the first host power supply control contact J-1 and the second host power supply control contact J-2 are controlled in the output of safety relay unit, also are connected to scram button and SR with the safety relay unit.
During installation, device Host is arranged in security fence, at the protective door of security fence safety door switch (normality is lock-out state) is installed, and is provided with open the door request button, indicator lamp, scram button and SR near protective door.
Operating personnel's wish enters the main frame zone by the protective door on the fence, at first should be by downward swing door request button, after finishing sawing task and reposition, main frame sends signal to programmable controller, programmable controller output signal control safety door switch discharges, this moment, indicator lamp became green, protective door can be opened, and allows operating personnel to enter;
When protective door is opened, indicator lamp is green flicker, safety door switch signals to the safety relay unit, safety relay unit controls the first host power supply control contact J-1 and the second host power supply control contact J-2 disconnect, dual cut-out main frame electrical source of power enters main frame region operation personnel's safety with guarantee;
Shut the protective door rear indicator light and become green when operating personnel leave the main frame zone, safety door switch becomes lock-out state, press safety relay unit controls main contactor adhesive behind the SR, the first host power supply control contact J-1 and the second host power supply control contact J-2 are closed, connect the main frame electrical source of power, indicator lamp becomes redness.
As when falling in emergency, can press scram button, the safety relay unit then controls the first host power supply control contact J-1 and the second host power supply control contact J-2 disconnects dual cut-out main frame electrical source of power.
Claims (1)
1. sawing machine safety device, the sawing machine main frame M that joins by fuse and power supply is arranged, it is characterized in that: between described fuse and sawing machine main frame M, be serially connected with electric machine controller, the first host power supply control contact J-1 and the second host power supply control contact J-2; Be provided with programmable controller, be connected to the request button that opens the door with programmable controller, electric machine controller, safety door switch and indicator lamp are controlled respectively in the output of programmable controller, be connected to the safety relay unit with safety door switch, the first host power supply control contact J-1 and the second host power supply control contact J-2 are controlled in the output of safety relay unit, also are connected to scram button and SR with the safety relay unit.
