Description
Technical field
The present invention relates to a kind of device that is used to measure the volume change of at least one textile fiber band, especially for the device of equipment such as drawing frame, carding machine, combing machine.
Background technology
Textile fibres can be natural as cotton and other natural fiber etc., also can be synthetic.
So-called at present " tongue-and-groove " device is used for the for example quality monitoring and the adjustment automatically of textile industry equipment such as drawing frame, carding machine, combing machine.
This device generally includes two wheels that wheel shaft is parallel, wheelspan is variable, between said two wheels, has slidably drawn at least one textile fiber band.
First round in this two-wheeled is engaged in second ring groove of taking turns with its circumferential hoop, and this ring groove is opened on the second outer rim place of taking turns, and shape is corresponding with circumferential hoop.
This two-wheeled is pressed onto each other together by elastic device and moves apart/shift to another to allow movable wheel to depend on the instant cross sectional shape of at least one band and take turns, and said band is pressed in second groove of taking turns by the circumferential hoop of the first round.
Movable wheel is connected to measurement mechanism to measure the displacement of said movable wheel.
The data of volume change about one or more band are sent to self-regulated module and computing machine from measurement mechanism; The ratio speed change of said self-regulated module and computer control roller---for example the prestretching roller in the drawing frame---is so that handled quality of fiber conformance with standard and reach optimum.
In normally used " tongue-and-groove " device, movable wheel is constrained at place, carriage end around himself axis rotation, and the other end of carriage is connected to and installs the element that the frame of the equipment of this device becomes one pivotally.
Therefore, movable wheel can move apart/shift to fast pulley with circular motion.
The from then on movable wheel of longitudinal rod or like radially extends with respect to the pin that connects with the activity wheel; This longitudinal rod becomes one with movable wheel and supports parts at its free end, and the displacement of said parts is detected by the analog sensor such as capacitive transducer.
Said bar is in order to amplify the activity wheel axis displacement that is detected by analog sensor, and this signal is converted into digital signal and is used for the self-regulated operation then.
Though said apparatus has obtained extensive employing and working condition is fairly good, they still have some shortcomings.
At first, as previously mentioned, one type of prior art syringe uses analogue means to come detection signal, carries out the mould/number conversion of signal then.
This conversion causes a little precision to reduce inevitably.
Yet; Because analog sensor shows different readings according to the artificial atmosphere situation in the buildings; Even, also must above-mentioned precision be reduced the situation that usually receive such environmental effects such as temperature and humidity with analog sensor and consider so do not consider to place the geographic area of the buildings of said equipment.
In addition, the passband that this analogue means has extremely narrow---promptly 10 to 20Hz scope---.
Summary of the invention
Fundamental purpose of the present invention provides a kind of volume change that is used to measure at least one textile fiber band to overcome the device of prior art shortcoming, and this device is especially for equipment such as drawing frame, carding machine, combing machines.
In order to realize above-mentioned target, free-revving engine of the present invention provides a kind of device that is used to measure the volume change of at least one textile fiber band, its can with than prior-art devices more directly and accurate way obtain signal.
