Abstract

The present invention is set out by the electronic devices and components in the spinning machine (9,10).It is the element as frequency converter and so on, and they produce a lot of heats, to such an extent as to need dispel the heat.Therefore they are provided with fin (16), and it extend in the exhaust stream (2), flows flying dust, dust and the sucking-off from the zone of weaving of other impurity by this exhaust.This exhaust stream (2) is removed its impurity in filter (5), and blocks by filter is increased.This has reduced its volume and has reduced its cooling effect thus.However, overheated for fear of electronic devices and components (9,10), heat sensor (17) need be set, this heat sensor transmits signal to control appliance (12) when temperature does not rise with being allowed to, and this signal indicates the necessity of cleaning filtration.This indicating can be carried out step by step, and final result is to interrupt the power supply of electronic devices and components or stop driving mechanism.

Description

The spinning machine that has frequency converter

Technical field

The present invention relates to a kind ofly have electronic devices and components, especially have the spinning machine (Spinnereimaschine) of frequency converter (Frequenz-umrichtern), these electronic devices and components extend in the exhaust stream of carrying in blast pipe with fin.

Background technology

Spinning machine has electronic devices and components, and these elements produce a lot of heats, to such an extent as to need dispel the heat.Obviously, such electronic devices and components are provided with fin, and these fin extend in the exhaust stream, with the sucking-off from the zone of weaving of flying dust, dust and analog.This is that with exhaust stream enough volumes (Volumen) to be arranged be precondition.The contaminant removal that to together carry by filter falls because this exhaust fails to be convened for lack of a quorum, and along with the increase of filter lining (Belag), has reduced its volume.Therefore also reduced the cooling effect that produces by it.

Summary of the invention

Therefore task of the present invention is, the temperature that rises in the attention electronic devices and components, and this may be owing to the filter lining that increases causes.This task can be finished by a kind of spinning machine that has electronic devices and components, especially frequency converter, these electronic devices and components extend in the exhaust stream of carrying in blast pipe with fin, according to the present invention, described electronic devices and components are provided with heat sensor, this heat sensor does not provide caution signal to control appliance when the temperature of electronic devices and components does not raise with being allowed to, this control appliance indicates the cleaning necessity of at least one filter in exhaust stream with caution signal.

Suppose that in initial scheme temperature in the electronic devices and components rises and is because impurity increases the lining of filter and the volume reducing that flows by exhaust thus causes.Therefore at first pointed out the necessity of cleaning and filtering.If carried out this cleaning, but still report the temperature that rises, other reason is arranged certainly, these reasons must be found.

Indicating of cleaning necessity about filter can be carried out step by step, and in the stage in the end, electronic devices and components are closed, and spinning machine is stopped, so that avoid injuring electronic devices and components.

Description of drawings

Accompanying drawing schematically shows the structural system in the spinning machine vertical view.

The specific embodiment

Spinning machine, for example ring spinner or roving frame, have a discharge duct 1, the air that is loaded with flying dust and/or dust is inhaled into this discharge duct 1 along the direction of arrow 2 or from the broken string sucking-off position (Fadenbruch-Absaugstellen) that does not illustrate by fan 3 here.After having accepted to be loaded with the air of flying dust and/or dust, it is through a cleaner 4 (Filter-kasten), and in this cleaner 4, flying dust that is carrying and dust are stopped by one or more filter 5.Fan 3 can be blown into the spinning workshop along the direction of arrow 6 once more with the air that cleaned.This being blown into also can be realized with the apparatus of air conditioning, makes the spinning workshop need not bear the heat of output.

Spinning machine comprises a plurality of electric drive motors, shows wherein as example two with

reference number

7 and 8 here.Here can be the drive motors that is used for main shaft, blade or other operating mechanisms of spinning machine.It is the three-phase alternating current motor that rotating speed can change, and its rotating speed is determined by adjustable frequency converter 9 and 10.The supply frequency of being carried by lead 11 is through a control appliance 12, and is transported to

frequency converter

9 and 10 by lead 13.Tach signal is

output frequency converter

9 and 10 by control circuit 14, and

frequency converter

9 and 10 is controlled by motor circuit 15 according to this tach signal and outputed to

frequency motor

7 and 8, that be used for drive motors.

Frequency converter

9 and 10 comprises rectifier and transverter in addition, and they inevitably produce heat and have improved the temperature of frequency converter in service.In order to derive these heats and to prevent that frequency converter is overheated, frequency converter has fin 16, and it extend in the air-flow of discharge duct 1 abrim.The heat that is produced is derived by this air-flow.

Except the used heat of

frequency converter

9 and 10, other used heat electric or electronic component unit also can be derived by the air-flow in the blast pipe 1 on the spinning machine obviously, and they extend in the air-flow with fin equally.Therefore, if realize the power supply of spinning machine with direct current,

component unit

9,10 can only comprise transverter.

So only the lining that is not filtered device when the volume of air-flow 2 blocks too much with flying dust and dust, just in discharge duct 1, form derive enough heats with cooled gas flow 2.Therefore, filter must be cleaned once in a while or termly, thereby discharge its lining.If do not carry out this cleaning,, can cause the overheated of electric or electronic component unit, for

example frequency converter

9,10 and lost efficacy so owing to lack enough heats and derive.

In order to avoid this situation reliably, the electronics that is provided with thermal detector 17 is

parts

9,10 in groups, this detector 17 when surpassing the temperature of predesignating, by

signal line

18 or 19 to control appliance 12 output signals.This signal can be encoded according to the warm height that reaches, and is just probably higher along with the temperature that rises.Control appliance can carry out by stages to the reaction of this signal.

At first, control appliance 12 can indicate the necessity of cleaning and filtering 5 on display 20.If this is unbecoming within a certain period of time, perhaps this signal continues the temperature that report is risen, and can indicate the necessity of cleaning by an optical pointing device 21 or acoustic signal.If one or more electronics temperature of parts does not in groups descend after having cleaned filter 5 yet, other reason is arranged certainly, these reasons must be found.

If electric or electronics in groups the temperature in the parts reach the height of the danger that makes its inefficacy, last control appliance 12 can interruption of power supply, for this purpose, power supply lead wire 11/13 is conducted through control appliance.This is preferably under many circumstances, if control appliance controllably stops driving mechanism.The mistake of avoiding thus for example breaking and so on.

Electric or the electronics fin 16 of

parts

9,10 in groups stretches into discharge duct by discharge duct 1 in cleaner 4 back along airflow direction, and extend into thus in the air-flow that cleaned, and it is not impregnated in flying dust and dust thus.Discharge duct advantageously has smooth wall in this zone, fin can embed at an easy rate in this wall.

Fin 16 extend in the air-flow that cleaned, and not contaminated thus.Because filter 5 is not all to stop trickle dust in all cases, the opening that seals with removable lid 22 is set on the side that is positioned at the fin opposite of discharge duct 1, can arrive fin by this opening, be used for cleaning once in a while trickle dust.
