Description
The present invention relates to a kind of method and apparatus that is used to detect the crawler belt wearing and tearing of crawler type textile machine.
By US 4 982 767 is known crawler belt is equipped with some elements in order to detect crawler belt wearing and tearing, these elements are arranged on the thickness and length of crawler belt with distributing.These elements constitute like this, make its light that produces the wearing and tearing of expression crawler belt, signal electricity or electromagnetism.But such element has changed the structure of crawler belt, makes these elements can not be adapted to the crawler type textile machine of high-speed cruising particularly well.
Also known by US 5 318 077, the upper surface of crawler belt only partly leads on guide pad at the driving wheel place.And the wearing and tearing of crawler belt are determined by measuring non-targeting part.This abrasion detection requirement, the part of crawler belt does not lead on guide pad.The position that makes crawler belt lead on guide pad thus is subjected to wearing and tearing quickly.
The objective of the invention is to, realize a kind of method and apparatus that detects the crawler belt wearing and tearing, make the special construction and/or the guiding that detect with crawler belt irrelevant.
This purpose realizes thus, utilize crawler belt and/or be in the characteristic parameter of the temperature of contacting structure parts as the crawler belt wearing and tearing with crawler belt.
The inventor is known, crawler belt and change according to the wearing and tearing of crawler belt at run duration with temperature that crawler belt is in the contacting structure parts.This effect is utilized, so as by crawler belt and/or find out the degree of wear of crawler belt with the temperature that crawler belt is in the contacting structure parts.This detection method is in fact irrelevant with caterpillar belt structure and guide frame.Therefore can realize designing best caterpillar belt structure and director element shape so that crawler belt accurately leads because can know exactly, which constantly crawler belt experience wear get and can not realize desired function more reliably.
For first realization of the present invention is the temperature of directly obtaining crawler belt.This point for example realizes by the infrared detection device that is arranged on the appropriate location.But in most of the cases, the temperature that obtains crawler belt indirectly is just enough in practice.To this, be favourable if record the temperature of the structure member that on crawler belt, is directed to.
In another kind of design of the present invention, calculate the temperature difference between the temperature of the temperature directly or indirectly obtain and the acquisition that is spaced a distance at measurement point.Get rid of the influence of environment temperature by this method.
Purpose of the present invention realizes by a kind of device, wherein arranges a calculation element, and is that this calculation element calculates crawler belt and/or be in the characteristic parameter of the temperature of contacting structure parts as the crawler belt wearing and tearing with crawler belt.
In another kind of design of the present invention, preferably do so to arrange, first temperature sensor and second temperature sensor are connected to calculation element, first temperature sensor more directly obtains temperature near crawler belt, and second temperature sensor with the position of track space one segment distance on obtain temperature.
Be subordinated to a guide pad for preferred form of implementation first temperature sensor, guide pad guarantees crawler belt and driving wheel engagement.This position is positioned at the race outside and therefore is easy to touch.Have advantage ground at this and do so to arrange, the rack arrangement of being made by Heat Conduction Material is on guide pad, and support is being fixed second temperature sensor in the face of fixing first temperature sensor on the position of guide pad on the position away from guide pad.The temperature sensor protectorate is arranged on internal stent, and the danger that is damaged like this is very little.
In another kind of design of the present invention, do so to arrange, to the additional input unit that is used to import fiducial value of calculation element.Can import a numerical value by the input unit operating personnel, this numerical value and temperature of being obtained or the temperature profile that is obtained be compared, and wear and tear by this this crawler belt that to change of relatively finding by calculation element.
In another kind of design of the present invention indicator is connected to calculation element, indicator for displaying goes out the degree of wear of crawler belt.Operating personnel can discern thus even impel operating personnel to notice, when will change crawler belt, to continue to guarantee best weaving condition.
Other features and advantages of the present invention provide by the description of following described form of implementation in the accompanying drawings.
Shown in Figure 1 is one have a driving wheel and with a sectional view that is useful on the crawler type textile machine of the device that obtains the crawler belt wear condition,
Shown in Figure 2 is a sectional view along straight line II-II in Fig. 1,
The partial section of the form of implementation of a variation that is similar to Fig. 1 that shown in Figure 3 is.
Local figure at the crawler type textile machine shown in Fig. 1 comprises crawler belt 1, and crawler belt is furnished with grouser in the mode that is not shown specifically, and gear piece is used for weft yarn is sent to the race of crawler type textile machine.Crawler belt 1 is by back and forth driving wheel 2 drivings of rotation.As shown in Figure 2, apart from being furnished with perforate, the tip edge of driving wheel 2 meshes into perforate to crawler belt with clocklike.Crawler belt 1 is fixed on the circumference of driving wheel 2 like this by board- like director element 3,4, and the perforate sequence of the tip edge of driving wheel 2 and crawler belt 1 keeps engagement like this.Board- like director element 3,4 is adjusted to the direction tangent with driving wheel 2 basically.Director element is arranged on the support 5,13, and these supports itself are fixed on the frame of crawler type textile machine by the fixture that does not illustrate.
On support 5, arrange first temperature sensor 6.This temperature sensor 6 is arranged on this position, position, turns to the circumferencial direction of driving wheel 2 from horizontal direction at this position crawler belt 1.Temperature sensor 6 is arranged near the director element 3, and the temperature of sensor acquisition director element 3 also obtains the temperature of crawler belt 1 thus indirectly like this.
Settle the support 5 of two temperature sensors 6,7 to make therein by the good material of heat conduction, for example aluminium.This support 5 contacts with director element 3, and but director element is made by heat conduction wear-resisting material, for example steel.The heat transferred temperature sensor 6 and 7 that produces by the friction between crawler belt 1 and director element 3.
The present invention is derived from such understanding, and when crawler belt 1 progressively weares and teares, when crawler belt 1 attenuation, the temperature of the variations in temperature of crawler belt 1 and/or director element 3 also changes.This reason may be that crawler belt 1 changes with respect to the position of director element 3, makes friction between the two also change.For this textile machine, wearing and tearing generally can cause the friction between crawler belt 1 and the director element 3 to increase, and also make thus because fricative heat increases.This just is used to detect the wearing and tearing of crawler belt, estimates the wearing and tearing of crawler belt 1 as characteristic parameter by temperature.
Estimate possibility for first kind and be,, then can determine crawler belt 1 attenuation and wearing and tearing on the whole if the temperature that is recorded by temperature sensor 6 exceeds set-point.This set-point is by input block 10 input computing units 8.Computing unit 8 for example can give controlling organization 11 1 signals then, when exceeding set-point, then impels the crawler type textile machine to shut down.Also can send a caution signal to this controlling organization, engage light for example, to cause operating personnel's attention: crawler belt 1 is experience wear, therefore needs to change.One or more signals also can directly be passed to indicator 9 optics or acoustics by calculation element 8.
The wearing and tearing of crawler belt preferably detect thus, promptly calculate by the measured temperature of temperature sensor 6 and by the difference between the measured temperature of temperature sensor 7.For example whether the detected temperatures difference exceeds the set-point that inputs to computing unit 8 by input block 10.This has advantage, because can get rid of the influence of environment temperature by this method, and for example influence of spinning and weaving workshop temperature rising.Measured temperature difference is basically just because the higher friction that is caused owing to wearing and tearing between crawler belt 1 and the director element 3 is caused.Therefore this temperature difference is the numerical value of temperature representative crawler belt 1 and/or director element 3 that has nothing to do with environment temperature.Although temperature sensor 6 and temperature sensor 7 are arranged on the same support, they still measure different temperature.Temperature sensor 6 measured temperature depend primarily on the friction between crawler belt 1 and the director element 3 because sensor more directly be arranged in the position that produces frictional heat near.In contrast, in the set position of temperature sensor 7, support 5 has been dispersed into heat in the environment basically.
For the director element according to the embodiment crawler belt 1 of Fig. 3 is a guide pad 12, and first and second temperature sensors 6,7 corresponding to Fig. 1 and 2 illustrated embodiment are set in guide pad, and sensor is connected to computing unit 8.Temperature sensor can certainly be arranged in other position, on the guide pad 14 that for example is arranged on the guide pad 13 or arranges with driving wheel 2 spacing distances.
Determined, wanted high by the measured temperature value of temperature sensor 6 and by temperature sensor 6 is relative with 7 measured temperature differences for new crawler belt 1.After crawler belt running several hrs, temperature and temperature difference descend and enter runtime value.But along with the increase temperature value and the temperature difference of crawler belt wearing and tearing raises again.The dangerous values of known crawler belt wearing and tearing occurs after 10,000 hours or longer running time usually.
For the wearing and tearing that detect crawler belt 1 also can calculate through after a while the variation of temperature or the variation of temperature difference.Equally also can calculate the variation of when connecting the machine of original stall this variation of temperature or temperature difference, promptly how soon temperature or temperature difference raise after connecting textile machine.
Can realize by the present invention, determine more exactly when must change for every crawler belt.This will make crawler belt be used as far as possible for a long time.This also has advantage with comparing with regard to the method for changing every crawler belt according to schedule after certain duration of runs.Can in time find the crawler belt that weares and teares in advance and prevent the crawler belt fracture by the present invention.Can use for more time than changing the determined time according to schedule for the crawler belt slower equally than normal wear.
The present invention is not limited to the embodiment of only exemplary expression.Especially can measure temperature or temperature difference by alternate manner, for example in other position or by other temperature sensor, for example measure by infrared detection device.Protection domain is only determined by claim.
