Description
Technical field
The utility model relates to the slipping of the belt detecting device of belt feeder.
Background technology
For the slipping of the belt that prevents belt system has all been installed the slipping of the belt detecting device.The slipping of the belt detecting device detects by the speed to belt, judges whether belt feeder transships, and whether belt skids because of overrunning.At present, existing slipping of the belt detecting device adopts speed relay to realize that the speed of belt detects, and the detection roller of speed relay is installed in the reverse side of belt feeder, when the speed of roller run to certain after relay junction closure or disconnection.But this device is installed inconvenient, and reliability is low, and the life-span is short, and the life-span of the detecting device that skids generally has only about two months, and the misoperation situation is more, and is bigger to producing influence.
The utility model content
Technical problem to be solved in the utility model provides a kind of belt feeder slipping of the belt detecting device, overcomes the existing not high defective of device reliability of surveying.
For solving the problems of the technologies described above, the technical scheme of the belt feeder slipping of the belt detecting device that the utility model proposes is: a kind of belt feeder slipping of the belt detecting device, comprise the belt speed detector, and it is characterized in that, also comprise Programmable Logic Controller; Described belt speed detector comprises gear, roller, trailing arm and magnetic induction sensor, described roller is connected with gear, can rotate synchronously, described roller is by the end of bearing installation at described trailing arm, the other end of described trailing arm is installed in the middle of the frame of belt feeder both sides, described roller contact belt, described gear is near described magnetic induction sensor, the output signal of described magnetic induction sensor inserts described Programmable Logic Controller by cable, and the output signal of described Programmable Logic Controller is sent to the belt control system.
As further improved plan, described roller is connected to coaxial the connection with gear.
The beneficial effects of the utility model: install simple; debugging is convenient; the belt speed or the judgement of skidding are accurate; the characteristics of long service life; can solve the hidden danger that prior art exists fully; and the controller programming technique is dissolved into checking system; make utilization more flexible; not only play the detection of slipping of the belt and putty; and can detect the mass flow of belt; the judgement belt has or not to be torn; weigh operation conditions of motor or the like; the perfect automatic guidance of belt transportation system; the controlling level of belt system is stepped to a new level; particularly adopt Programmable Logic Controller; various signals at belt system focus on, and have played the integrated protection function of belt feeder operation conditions.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is speed sensor of the present utility model mounting structure front view on belt feeder.
Fig. 2 is the lateral plan of speed sensor of the present utility model.
Fig. 3 is the birds-eye view of speed sensor of the present utility model.
The specific embodiment
As shown in Figure 1, installation shaft 4 in the middle of the belt feeder both sides frame 5, an end of trailing arm 2 is installed on the axle 4, and roller 1 is installed on the other end of trailing arm 2, roller 1 contact return belt 6, the side of trailing arm 2 has shielding output cable 3 to output to Programmable Logic Controller.
As Fig. 2, in conjunction with shown in Figure 3, roller 1 is installed on the axle 11 with gear 10, can rotate synchronously, the axle 11 by bearing installation at trailing arm 2 ends, magnetic induction sensor 7 is approaching with gear 10, and the shielding output cable 3 of magnetic induction sensor 7 connects Programmable Logic Controller by the opening 8 of trailing arm 2, and the output signal of Programmable Logic Controller is sent to the belt control system.Mounting hole 9 is the mounting hole site of Fig. 1 axis 4.
Its method of measurement is: roller is followed the return belt operation, the driven gear rotation.The rotation of magnetic induction sensor detection gear also produces one and the proportional impulse singla of belt speed; impulse singla inserts Programmable Logic Controller by the shielding output cable; Programmable Logic Controller calculates belt speed by the magnetic induction pulses number that receives; Programmable Logic Controller compares detected belt speed and given speed; specifically comprise the comparison of three phases: 1, start-up period, by cranking signal and given cranking time and detected belt speed belt feeder is protected.2, the operation phase, judge by run signal and detected belt speed whether belt skids or overload and belt tearing.3, stop phase is judged the whether adhesion of belt main contactor by danger signal and detected belt speed.The output signal of Programmable Logic Controller is sent to the controller load module of belt system, and this output signal plays the effect of control belt system operation.
The speed sensor of this specific embodiment is input as two-way rotation 2 to 450rpm; be output as 60 pulse/commentaries on classics; 2 to 450Hz; the i.e. impulse singla of 150.4 pulse/rice; adopt the belt feeder slipping of the belt detecting device of this specific embodiment; make the detection and the protection system of belt feeder more perfect, the detection reliability that skids reaches more than 99.9%.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
