The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
With reference to figure 2, the utility model provides a kind of belt feeder, and this belt feeder comprises the belt 1 of cycle operation.According to embodiment of the present utility model, the one or both sides of belt 1 with belt 1 position separately, photoelectric switch is set.This photoelectric switch has projector and the receptor of mutual correlation.Photoelectric switch is converted to received current optical signal and penetrates on projector, and receptor is again according to the strong and weak of the light receiving or have or not the position of belt 1 is surveyed.According to embodiment of the present utility model, the one in projector and receptor is arranged on the top of belt 1, and another one is arranged on the below of belt 1.Like this, when sideslip occurs belt 1, belt 1 can enter into the surveyed area of photoelectric switch, and the light signal generating that projector is sent is blocked.At this moment, photoelectric switch will send belt deviation signal.Because the detection mode of photoelectric switch is contactless, therefore can avoids rubbing between belt 1 and deviation detecting device, thereby can prevent that belt 1 and deviation detecting device from wearing and tearing.
According to preferred embodiment of the present utility model, in the both sides of belt 1, be provided with photoelectric switch.And the photoelectric switch of both sides arranges symmetrically along the Width of belt 1.Like this, during any side sideslip of belt 1 in both sides, can be detected by photoelectric switch.And, the photoelectric switch of both sides is arranged symmetrically, be conducive to the testing conditions of both sides to carry out the setting of standard.
Continuation is with reference to figure 2, and according to embodiment of the present utility model, photoelectric switch comprises the first photoelectric switch 2 and the second photoelectric switch 3.Wherein, the first photoelectric switch 2 arranges near belt 1, for detection of the light sideslip of belt; The second photoelectric switch 3 arranges away from belt 1, for detection of the heavy sideslip of belt.That is to say, when light sideslip occurs for belt 1, belt 1 can block the optical signal that the projector of the first photoelectric switch 2 sends, and causes the first photoelectric switch 2 to send the signal that target occurs.When heavy sideslip occurs for belt 1, belt 1 can block the optical signal that the projector of the second photoelectric switch 3 sends, and causes the second photoelectric switch 3 to send the signal that target occurs.Certainly, when heavy sideslip occurs for belt 1, belt 1 also can block the optical signal that the projector of the first photoelectric switch 2 sends, but now system can preferentially receive the signal that the second photoelectric switch 3 sends.According to embodiment of the present utility model, along the Width of belt 1, the spacing between the first photoelectric switch 2 and the second photoelectric switch 3 is 9cm to 11cm.That is,, when belt 1 continues sideslip 9cm to 11cm again for light sideslip, can think that heavy sideslip accident has occurred belt 1.
In more detail, according to embodiment of the present utility model, belt feeder also comprises control setup, and the input end of this control setup is electrically connected to the mouth of photoelectric switch.That is to say, the signal that the first photoelectric switch 2 and the second photoelectric switch 3 send is all sent in control setup, thereby control, relevant electric contact is opened or closure.
More specifically, control setup comprises alarm module and start and stop module.Wherein, when the first photoelectric switch 2 sends target and occurs signal, in response to this target, there is signal, the light offset signals of alarm module output belt.When the second photoelectric switch 3 sends target and occurs signal, in response to this target, there is signal, the heavy offset signals of alarm module output belt.Meanwhile, start and stop module output danger signal, stops the drive motor of belt feeder.Further, according to embodiment of the present utility model, in the circuit of the output danger signal of start and stop module, be in series with the electric contact of retarded closing.Preferably, be 10 seconds to 15 seconds the delay time of this electric contact.That is,, when start and stop module receives the signal that the second photoelectric switch 3 sends, postpone just to export danger signal after 10 seconds to 15 seconds.Like this, can prevent the frequent shutdown that the instantaneous sideslip of belt feeder causes when the foreign matter such as instantaneous return or coal cinder blocks suddenly the optical signal that the projector of the second photoelectric switch 3 sends again.
Still with reference to figure 2, according to embodiment of the present utility model, belt feeder comprises human-computer interaction interface, and the mouth of alarm module is electrically connected to human-computer interaction interface.Like this, the heavy offset signals of the light offset signals of belt and belt can be presented on human-computer interaction interface, makes operating personal can see at a glance what happens, to suitably carry out in time subsequent treatment.
In addition, according to embodiment of the present utility model, belt feeder also comprises mounting bracket 4, and photoelectric switch is removably connected on mounting bracket 4, so that Maintenance and Repair.Further, on mounting bracket 4, offer for the mounting groove of photoelectric switch is installed, and the length direction of this mounting groove is along the Width extension of belt 1.Like this, the position of the first photoelectric switch 2 and the second photoelectric switch 3 can be adjusted along the Width of belt 1, to adapt to different operating modes.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, between various embodiment of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
