As shown in Figure 3, in order to prolong the service life of said monitoring device, and improve the accuracy of said monitoring device; Preferably; Detective cell 20 can be near switch, and this detective cell 20 is fixedly installed on the support of said belt feeder, and swing arm 10 is provided with signal iron.When swing arm 10 swing with moving of the material on the belt 30, said signal iron was near said near switch, when the said scope that can survey near switch of said signal iron arrival, can trigger this near switch.Should send signal to said processing unit near switch.
In this embodiment, detective cell 20 is fixed on the support of said belt feeder, is not moved, and therefore, is not easy to be damaged, thereby has improved the service life of said monitoring device.And, comparatively sensitive near switch, can detect the pendulum angle of swing arm 10 exactly.Should be noted in the discussion above that when swing arm is in vertical position the distance between the signal iron on detective cell 20 and the swing arm 10 should be between 10 to 30mm.
In the described monitoring device of the utility model, can judge the amount of the material on the belt 30 of said belt feeder according to the angle of swing arm 10 swing.The angle of swing arm 10 swings is big more, explains that then the material of transportation on the belt 30 is many more.For the ease of the amount of the operating personal judgement material that belt feeder transported, preferably, detective cell 20 can be for a plurality of, and these a plurality of detective cells 20 are spaced apart and arranged on the support of said belt feeder along the transporting direction of belt 30.
Material on belt 30 more after a little while, said signal iron can trigger the detective cell 20 nearer apart from swing arm 10, the material on belt 30 more for a long time, said signal iron can trigger the detective cell 20 far away apart from swing arm 10.
When the angle of swing arm 10 swing was between 20 °～30 °, the material on the belt 30 was less, and this moment, said belt feeder was in light condition; When the angle of swing arm 10 swing was between 30 °～45 °, the material on the belt 30 was moderate, and this moment, said belt feeder was in fully laden; When the angle of swing arm 10 swing was between 45 °～60 °, the material on the belt 30 was more, and this moment, said belt feeder was in overload condition.
Correspondingly, detective cell 20 can comprise first detective cell that is used to survey the swing of said swing arm 10 in 20 °～30 ° scopes, the 3rd detective cell that is used to survey second detective cell of the swing of said swing arm 10 in 30 °～45 ° scopes and is used to survey the swing of said swing arm 10 in 45 °～60 ° scopes.
Said first detective cell, second detective cell and the 3rd detective cell can send various signals to said processing unit, and processing unit sends different instructions according to various signals, thereby are convenient to the condition of loading that the operator monitors belt 30.
Shown in Fig. 1 to 3, for the ease of the installation of detective cell 20, preferably, shown in monitoring device can also comprise detective cell bearing 21, detective cell 20 is fixed on the support of said belt feeder through said detective cell bearing 21.
Preferably, said processing unit can comprise isolated amplifier, and the signal that detective cell 20 is sent carries out filtering, amplification.Processing unit can be sent to control unit after with signal conditioning, thereby carries out exercises.
Above content is described detective cell 20 in detail, hereinafter will describe a kind of embodiment of roll wheel assembly 40.
As shown in Figure 4, roll wheel assembly 40 can comprise the bearing pin 43 that is fixed on the swing arm 10, is set with bearing 42 on this bearing pin 43, and roller 41 is sleeved on bearing 42 outsides.The outer ring of roller 41 and bearing 42 can freely be rotated around bearing pin 43, thereby has further reduced the wearing and tearing of material pair roller 41 mobile on the belt 30.
Another aspect as the utility model; A kind of belt feeder also is provided; Wherein, This belt feeder comprises the monitoring device that is used to monitor the material on the belt feeder, the PLC modular unit that is electrically connected with the processing unit of this monitoring device and the annunciator that is electrically connected with this PLC modular unit, and said monitoring device is the above-mentioned monitoring device that the utility model provided.
The detective cell 20 of said monitoring device detect be rocked to predetermined angular (as, 20 °) swing arm 10 after, signal is passed to processing unit, after the processing (being generally filtering, amplification) of this processing unit, this signal is passed to the PLC modular unit.Through comparing, can judge whether that alarm condition exists with setting voltage.When alarm condition exists, start annunciator.
For example, when said monitoring device comprised first detective cell, second detective cell and the 3rd detective cell, said annunciator can be versicolor indicator lamp.The operator can judge the condition of loading of belt feeder according to the color of annunciator.
When said monitoring device was monitored less than materials flow for a long time, PLC modular unit may command belt feeder was out of service, with energy savings.
Preferably, said belt feeder can also comprise the automatic water system that is electrically connected with said PLC modular unit, and this automatic water system is arranged on the support of said belt feeder, and is positioned at the top of the belt 30 of said belt feeder.When said monitoring device monitors when on the belt 30 material being arranged, PLC modular unit control automatic water system capable of using is sprinkled water to material.
