Definitions
- the invention relates to a spinning machine with electronic components, in particular frequency converters, which protrude with cooling fins in a stirred in an exhaust duct exhaust air flow.
- Spinning machines have electronic components that generate so much heat that they require cooling. It is known to provide such electronic components with cooling surfaces that protrude into the exhaust air stream, are sucked with the flight, dust, thread residues and the like from the spinning area. This presupposes that this exhaust air flow has sufficient volume. Since this exhaust air flow is freed by filters from the entrained impurities, its volume decreases as the lining of the filter increases. This also reduces the cooling effect caused by it.
- the object of the invention was accordingly to make attentive increasing temperatures in the electronic components, which may be caused by the increasing coating of the filter. It solves this problem by the features mentioned in the characterizing part of the main claim.
- a spinning machine for example, a ring spinning machine or a roving, has a suction duct 1, in the loaded with air and / or dust air in the direction of arrow 2, for example.
- Fadenbruch- suction is sucked by a fan 3.
- a filter box 4 After receiving the flight- and / or dust-laden air this passes through a filter box 4, in which the entrained flight and dust is held back by one or more filters 5.
- the fan 3 can blow out the cleaned air in the direction of arrow 6 back into the spinning room.
- the blowing can also be done in the air conditioning, so as not to burden the spinning room with the heat given off.
- the spinning machine includes a plurality of electric drive motors, of which here beispiels ⁇ half two marked with the reference numerals 7 and 8 are shown. These may be drive motors for spindles, for wings or other working elements of the spinning machine. There are three-phase motors whose speed can be varied and whose speeds are determined by adjustable frequency converters 9 and 10. The supplied via a line 11 mains frequency passes through a control device 12 and is supplied via lines 13 to the frequency converters 9 and 10. The frequency converters 9 and 10 are fed via control lines 14, a speed signal, according to which they control the output via motor lines 15 to the motors 7 and 8 frequency for operating the motors.
- Frequency inverters 9 and 10 include rectifiers and inverters, which inevitably generate heat and increase the temperature of the frequency converters during operation. In order to dissipate this heat and to prevent overheating of the frequency converter, they have cooling ribs 16 which project into the air stream prevailing in the suction channel 1. The heat generated is dissipated by this air flow.
- the waste heat of the frequency converter 9 and 10 can be dissipated by the air flow in the exhaust duct 1, which then also with cooling fins in protrude this airflow.
- the units 9, 10 comprise only inverters.
- a sufficient heat laxative and cooling air flow 2 in the suction channel 1 is only given if its volume is not throttled too far by the lining of the filter 5 with flight and dust. It is therefore necessary to clean the filter from time to time or regularly, so to free from its coating. If this does not occur, this can lead to overheating and failure of the electrical or electronic components, that is, for example, the frequency converter 9, 10 due to a lack of sufficient heat dissipation.
- Thermofühlera 17 provided that emit a signal to the control device 12 on the signal lines 18 or 19 when a predetermined temperature is exceeded.
- the signal can be coded as a function of the level of the temperature reached, that is to say become higher with increasing temperature.
- the response of the control device to this signal can be stepped.
- the controller 12 may indicate on a display 20 the need to clean the filter 5. If this is not met within a certain time or if the signal further indicates increased temperature, the necessity of cleaning can be indicated by means of an optical display device 21 or with an acoustic signal. If the temperature in one or more of the electronic components does not decrease even after cleaning the filter 5, this must be another
- control device 12 can interrupt the mains supply - the mains supply line 11/13 is guided through this control device for this purpose. In many cases, however, it is more expedient for the control device to shut down the drives. As a result, errors such as thread breaks are avoided.
- the cooling fins 16 of the electrical or electronic assemblies 9, 10 protrude in the direction of the air flow through the suction channel 1 behind the filter box 4 in the suction and thus in the purified air stream, so they are not added by flight and dust.
- the suction channel has in this area advantageously a flat wall into which the cooling fins are easily inserted.
- the cooling fins 16 protrude into the cleaned air stream and are thus not exposed to contamination. Since the filter 5 but usually does not retain particulate matter, are on the side opposite the cooling fins side of the suction channel 1 with removable lids 22 closed openings arranged through which the cooling fins are accessible to clean them occasionally of particulate matter.
