Description

The automatic deviation rectifying device of bidirectional movement belt conveyer and automatic correction method
Technical field
The present invention relates to bidirectional movement belt conveyer, particularly, relate to a kind of short range of frequent start-stop, bidirectional movement, automatic deviation rectifying device and automatic correction method of underload belt conveyer of being mainly used in.
Background technology
Short range, underload belt conveyer are widely used in the departments such as chemical industry, light industry, food, grain, post and telecommunications, for delivery of various loose unpacked materials and work piece.
Common most of belt conveyers are unidirectional operations, the belt conveyer of unidirectional operation is in zero load and have the heeling condition by adjustment certain " modified roller " while carrying debugging, roller takes measures such as " double-cone rollers " with comprehensive various sideslip factors end to end, can realize one section of steady running in period.After date when equipment moves one section, if there is or approach serious sideslip situation, be tending towards ideal position through the artificial reset load-transfer device of adjusting, then start operation can continue again one period, so go round and begin again, the belt conveyer of Unidirectional still can normally use during without automatic deviation correction measure.
Correction valve is domestic appearance recently a kind of gas path control valve for belt conveyer automatic deviation correction, and its prototype is pneumatic proportional balance cock.Usually, in pneumatic circuit design, if used this class component of proportional balancing valve to control actr (cylinder or air bag), can realize the actr function of stop motion at an arbitrary position, this function meets the demand of " Dynamic Closed Loop Control (exporting feedback quantity by input) ".
Correction valve is a kind of machine control valve, its input shaft (outside face annular knurl) can swing in positive and negative both direction certain angle scope (as 0~62 °), and each party exports through correction valve to the pivot angle in angular range (0~62 °), control, corresponding cylinder are retracted to each length between stretching out completely completely, are in theory mapping relations one by one.Correction valve product itself can be inputted extraneous information by both direction, and the needs of input are installed, obtained to such product design by meeting in equipment both sides.
Fig. 1 utilizes correction valve to realize the principle schematic of Unidirectional belt conveyer automatic deviation correction, its deviation-rectifying system is a kind of closed loop control system, and its feedback control procedure is: the position that belt edges position → measuring roll → pendular body for input → correction valve → cylinder → deviation rectification roller → load-transfer device is new.The mark that its dynamical equilibrium is set up is: deviation rectification roller deflects into lucky comprehensive various sideslip factors behind certain orientation, and obvious displacement no longer occurs load-transfer device.
If the demand of certain operating mode is belt conveyer frequent start-stop, bidirectional movement, the deviation correcting technology that was now originally applicable to Unidirectional will lose efficacy, and phenomenon is that sideslip situation is comparatively stable during towards the operation of direction, when commutation operation, load-transfer device exceeds camber control scope very soon, cannot normally use.
Analyze wherein reason in conjunction with Fig. 1: suppose that certain conveyer backhaul district running direction of conveyor belt is identical with the service direction shown in Fig. 1; when shutdown, the orientation of deviation rectification roller 5 is certain angular deflection keeping left between lateral areas; now; if commutation operation; suppose that again the backhaul district belt deflection tendency that material load causes is downward sideslip; be backhaul district running direction of conveyor belt to the right, simultaneously downwards sideslip.By closed loop control, when backhaul district load-transfer device moves to the right, downward sideslip, measuring roll 32 is just pressed downward, and consequently cylinder 4 further stretches out, and causes backhaul district load-transfer device to aggravate downward sideslip, loses rectifying effect.
For Fig. 1, also have a place it is to be noted: along service direction, the belt edge before backhaul district load-transfer device contact deviation rectification roller 5 is only the rational layout points of measuring roll.Can explain based on this point: even if it is still infeasible to set up outer guide's two position four-way solenoid valves between correction valve and cylinder.
Comprehensive above analysis, can be clear and definite: in any case, correct deviation rectification roller function should be to impel all the time the factor of load-transfer device to ideal position fallback, and the correction valve of applying " tool dynamic correcting effect " is also the link that should not abandon.Therefore new effective term is created in the use that is necessary for correction valve, realizes way traffic automatic deviation correction technology with this, ensures the long-term stability operation of equipment under way traffic operating mode.
