Definitions
- the invention relates to a method and a device for controlling the Induced draft by changing the speed of a fan motor in a yarn breakage extraction system a textile machine.
- the invention is particularly suitable for use Ring spinning machines and roving (flyer) provided.
- the prior art already includes a device by means of which the negative pressure in a yarn breakage extraction system is controlled by changing the speed of the fan motor to a set amount (US-PS 4,753,665) .
- This known device responds to negative influences in practice, for example, when clogging the suction, either not at all or only insufficiently.
- the object of the present invention is a method or to provide a device of the type mentioned, which or which reacts much more flexibly to the sources of error that occur in practice.
- This object is achieved in that a standard speed of Fan motor is fixed to achieve the negative pressure, after which the Speed of the fan motor is controlled so that reaches a set negative pressure and is respected.
- a standard speed of the fan motor to specify, with a lying in a normal range, normal negative pressure is reached. Only if this negative pressure is reached, the control is activated, this controls the speed of the fan motor so that a desired adjustable negative pressure is reached and maintained.
- At this predetermined standard speed is also switched when the sensor recorded negative pressure significantly exceeds or falls below the limits that can be set. This can for example when opening the filter chamber for removing the Waste, in case of failure of the negative pressure sensing sensor, when clogging the Suction line or similar sources of error be the case. If the aforementioned sensor again feels a correct negative pressure, the control is reactivated. Lies the standard speed of the fan motor for a longer, adjustable time before is assume that there is a fault or damage, after which an error signal is emitted acoustically and / or optically.
- the device for regulating the induced draft by changing the speed of a fan motor has a controller connected to the fan motor to achieve the Vacuum at a given standard speed, the rules on a set negative pressure takes place.
- FIG. 1 is schematically in a ring spinning machine 1 with drafting a number represented by output top rollers 2.1 and output bottom rollers 2.2. Below These output sub-rollers 2.2 are suction tube 4, which are part of a Thread breakage extraction system are.
- This extraction system 10 has a filter box 16 with Filter plates 18, a fan 12 and a fan motor 14.
- the fan motor 14 is connected to a control unit 20, at least one sensor 22 and an optical and / or acoustically acting signaling device 24.
- Fig. 2 Diagram in which the size of the negative pressure is shown above the time axis t.
- the fan motor 14 via the control unit 20 operated with a - unregulated - speed, the one generally functional Standard negative pressure S generated. If after a short period of time T is determined via the sensor 22 that this negative pressure S is achieved, it is assume that the yarn breakage extraction system 10 is in order and the control unit 20 can switch to control. By regulating the fan motor 14 on regulated a speed with which a selectable vacuum U is reached. In the illustrated Example, this selected negative pressure U is higher than the standard negative pressure S, however, it could be lower.
- the switches Control unit 20 in such cases, the regulation and the fan motor 14 to its Standard speed. This is at least trying again, the standard negative pressure S build and hold and thus the machine at least in relation to the induced draft the yarn breakage extraction system 10 to remain in an operable state. If the Pressure drop not by clogging the suction line of the yarn breakage extraction system is caused, this is possible by means of the standard induced draft.
- the sensor 22 does not feel any negative pressure, the possibility must be expected that blockage of the suction line of the yarn breakage extraction system 10 is present. There this as a result of non-extracted fiber sliver to roll winding and thus machine damage can lead in this case is the time to turn on the signaling device to choose very short or to shut down the ring spinning machine 1 at all.
- the ring spinning machine remains operable even if the control fails.
- the fan motor 14 at the beginning has the purpose that the control via the control unit 20 only with intact suction system 10, for example, with the door closed Filter box 16 is activated.
- the standard speed of the fan motor 14 be approached even at a steep increase or decrease of the negative pressure can.
