Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
Below the utility model is described in detail by ore deposit hopper blocking autoalarm.
The utility model provides a kind of by ore deposit hopper blocking autoalarm, and this device comprises opto-electronic pickup and control setup.This opto-electronic pickup comprises projector and receptor, the hole transmitted beam that this projector and receptor are oppositely arranged respectively by funnel both sides and receiving beam.Control setup is used for when described receptor can not receive the beam signal of described projector transmitting, and determine described funnel blockade, the supplied materials sealing-tape machine controlling described funnel is out of service.
As shown in Figure 1, funnel 1 is fixed on funnel pedestal 6, and this funnel pedestal 6 can be concrete pedestal.These funnel 1 both sides are respectively arranged with relative hole 3.
Wherein, supplied materials sealing-tape machine 2 is higher than the height of funnel 1 both sides providing holes 3, and to funnel 1 convey materials, discharge sealing-tape machine 7 is positioned at below funnel 1, for dispatch material.
In addition, projector 4 and receptor 5 are installed on funnel 1 both sides external, and wherein projector 4 and receptor 5 are apart from can far can be near.This 4 projector and receptor 5 are respectively by relative hole 3 transmitted beam in funnel 1 both sides and receiving beam.Pass to receptor 5 when being sent light beam by projector 4 by the hole 3 arranged on funnel 1, when receptor 5 receives beam signal, export and do not change.Preferably, the opto-electronic pickup that the utility model uses adopts internationally renowned brand " Bang Na " opto-electronic pickup, this kind of opto-electronic pickup stable work in work, antidetonation and to penetrate dust ability strong.
It should be noted that, the sensor in the utility model not only can be fixed on funnel 1 pedestal, can also be fixing as being fixed on spud pile in other form modes, only otherwise stopped the light beam between projector 4 and receptor 5 by foreign object.
By with another specific embodiment, the scheme that the utility model provides is described in detail below.
Generally speaking, electromagnetic relay is made up of iron core, coil, armature, contact reed.As long as add certain voltage at coil two ends, certain electric current will be flow through in coil, thus generation galvanomagnetic effect, the pulling force that armature will overcome spring under the effect of electromagnetic attracting force is inhaled to iron core, thus the moving contact of band moving armature and break back contact (open contact) adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature will return to original position at the antagonistic force of spring, makes moving contact and original break back contact (normally closed contact) adhesive.The break back contact being in off-state when electromagnetic relay is not energized is called open contact, and the break back contact being in on-state is called normally closed contact.When electromagnetic relay obtains electric, open contact closes, and normally closed contact disconnects.
As shown in Figure 3, control setup comprises the first power supply 9, the first electromagnetic relay 10 be electrically connected with the first power supply 9, second source 12, the second electromagnetic relay 13 and the PLC14 be electrically connected with second source 12.It should be noted that the first power supply 9 is generally 0-30V direct supply, second source 12 is 24V direct supply.
As shown in Figure 2, when funnel 1 materials inside 8 is stacked into certain altitude break beam signal, receptor does not receive beam signal, export high level signal, conducting first electromagnetic relay 10 coil, at this moment the first electromagnetic relay 10 normally closed contact disconnects, and the 0-30V power supply be connected on this first electromagnetic relay 10 normally closed contact disconnects, make the second electromagnetic relay 13 coil losing electricity in PLC cabinet 11, the second electromagnetic relay 13 open contact in described PLC cabinet 11 recovers to disconnect, PLC14 and 24V power supply disconnects, PLC14 exports jam signal, so that supplied materials sealing-tape machine 2 stops convey materials, discharge sealing-tape machine 7 continues dispatch material.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings 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 concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible array mode.
In addition, also can carry out combination in any between various different embodiment of the present utility model, 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.
