Description
Technical field
Invention relates to a kind of spinning machine, it has a plurality of spinning position, they have a pressing zone with negative pressure work separately and are used to compress fiber strip, and ventilator with a plurality of generation negative pressure, these ventilator dispose respectively to a plurality of spinning position, wherein each ventilator has a monitoring device, and it is furnished with the operational factor of a ventilator relevant with negative pressure.
Background technology
The spinning machine of this pattern is learnt by DE103 48 225 A1 and is prior art.Each ventilator is driven by a driving belt in this spinning machine, and whether sufficient the tension force of belt should be exactly negative pressure yardstick.Each driving belt is furnished with an idler roller, and idler roller just changes its position and makes a switch motion when the tension force in the driving belt reduces.Known devices is based on following understanding: the power consumption of ventilator is directly proportional with the volume flow of being carried.Will carry the smaller volume flow when occurring stopping up in by the member of suction air, this causes power consumption to diminish and therefore causes reducing of accessory drive belt tension force forcibly.
But showed already in the practice that obstruction did not often appear at suction air is led in the member of ventilator, but in ventilator, especially in ventilator impeller itself.This obstruction causes ventilator impeller operation resistance big, and this can not be discerned by known monitoring device, because the power consumption of ventilator does not reduce, and therefore the tension force of driving belt does not reduce.
Summary of the invention
Task of the present invention provides a kind of monitoring device that is used for the spinning machine ventilator that starts described type, and it can detect in the pressing zone because the big caused negative pressure decline of the resistance of ventilator impeller.
This task solves by the following method: the operational factor of being monitored by monitoring device is the ventilator rotating speed.
Understanding of the present invention is, when just strengthening in ventilator axle running resistance in the ventilator or when fan impeller originally takes place to stop up on one's body, and has only consumption power to strengthen and could rotate.The ventilator axle is braked deceleration and just reduces by the volume flow that impeller transports.Therefore in the pressing zone, just no longer had needed negative pressure.
Be not only applicable to the bel-drivenn ventilator according to the monitoring to the ventilator rotating speed of the present invention, and be well suited for single electric motor driven ventilator.This single electric motor driven ventilator is for example disclosed by DE199 33 747 A1.
Except the running resistance that can detect the ventilator impeller, also has following advantage: can determine the obstruction in the member of ventilator that suction air is led according to monitoring device of the present invention.The ventilator rotating speed that diminishes when a kind of such obstruction occurring is not the little reason of volume flow, but is because the cross section that obstruction causes reduces.The volume flow that herein diminishes has caused the power consumption that ventilator is less, thereby especially when single electric motor driven ventilator the ventilator rotating speed is improved.
The monitoring of ventilator rotating speed can be much simpler than direct measurement and monitoring negative pressure, because B/P EGR Back Pressure Transducer EGR must carry out very bothersome adjustment.
Advantageously make monitoring device be provided with sensor, these sensors can be non-contactly and are not therefore had subsidiary friction loss ground to detect the ventilator rotating speed.These sensors can be equipped on ventilator impeller or axle simultaneously.If sensor is equipped on the ventilator axle, so advantageously be furnished with a kind of anti-sender unit that is rotatably fixed on the ventilator axle for monitoring device, it produces a kind of signal that is proportional to the ventilator rotating speed and changes.
Description of drawings
Other advantage of the present invention and feature are seen following to an explanation that embodiment did.Accompanying drawing is depicted as:
Fig. 1: represent that the drafter of a spinning position with the pressing zone of being joined and one produce the side view in partial cross-section that ventilator negative pressure, that drive by means of driving belt connects same monitoring device;
Fig. 2: the pressing zone of representing a plurality of spinning positions that belong to a suction channel and a ventilator separately is along the view on the arrow II direction among Fig. 1, and some of them member, especially drafter have then omitted.
The specific embodiment
Spinning machine, the especially a kind of ring spinner just partly expressed in Fig. 1 and 2, it comprises a plurality of machine sections 1,2 of arranging along the machine longitudinal direction.Such machine section 1,2 for example is furnished with four spinning positions 3 to 16 respectively, and wherein the quantity of spinning position fully can be bigger.
Each spinning position respectively is furnished with drafter 7 of cicada just itself, and what be placed on it is a pressing zone 8, and its planform itself is arbitrarily.
That each drafter 7 comprises is a plurality of, be herein three rollers to 9,10 and 11, they are made up of a driven lower roll that passes on the machine longitudinal direction and a pressure roller that is matched with each spinning position respectively in known manner.
On input direction A, respectively there are a fiber band or rove 12 to flow to drafter 7, then they are stretched to desirable fineness for 7 li at drafter always.And then described last roller to 11, be that the so-called outlet roller of drafter 7 is right, then obtain one stretched but still untwisted fiber strip 13.This fiber strip 13 is through described pressing zone 8 and be formed bundle here, therefore makes fiber strip 13 narrower and less villous, has generally speaking made full use of material better, and this finally causes intensity to improve.The outlet side of pressing zone 8 is the boundary with a clamping point 14, twists from the yarn 15 that is spun here.Yarn 15 flows to a unshowned twisting mechanism along feed direction B, for example a ring ingot.Clamping point 14 plays the effect of twisting locking for spinning twisting.
The pressing zone 8 of a plurality of spinning position 3 to 6 all is furnished with a special pipe 16, and it is arranged on the machine portion section 1 and forms a suction channel.Each spinning position 3 to 6 all is provided with a suction socket 17 on special pipe 16, and it extends upward and for example arrive always clamping point 14 in the transporter of fiber strip 13 basically.
As seen from Figure 2, machine section 2 equally also is furnished with a special pipe 16.
Each pressing zone 8 all is furnished with a narrow conveyer belt 18 concerning each spinning position, and this conveyer belt covers suction socket 17 separately and is designed to breathe freely.Advantageously be meant a kind of thin webbing for conveyer belt 18, have very thin pore.The outline of special pipe 16 is designed for the sliding surface of conveyer belt 18, wherein conveyer belt tightly surround special pipe 16 and on special pipe 16 around operation.What be used to drive conveyer belt 18 is a pinch roll 19, and it and special pipe 16 constitute described clamping point 14.Pinch roll 19 drives in a not shown manner and drives conveyer belt 18 by friction.
Each special pipe 16 comprises a suction socket 20, therefore that is to say on each machine section 1, for spinning position 3 suction socket 20 is arranged respectively to 6 herein.Special pipe 16 is connected on a suction hose or the suction tube 21.
Each suction tube 21 is furnished with self a ventilator, and it produces needed negative pressure.
Each ventilator 22 is driven by means of driving belt 24 separately.Each machine section 1,2 respectively is provided with a driving wheel 25 for driving belt 24.Each driving wheel 25 is fixed on the driving shaft 26, and this driving shaft passes along the machine longitudinal direction, and for example is driven from the main spindle box of spinning machine.Driving belt 24 can be furnished with a spring-loaded idler roller 32 separately.
Illustrated already: compressing of each fiber strip 13 all is the quality that is used for improving spinning yarn 15.Its condition is: the pressuring action for fiber strip 13 on each pressing zone 8 all has identical effect.Because work is carried out with negative pressure in pressing zone 8, therefore must pay attention to, make the negative pressure at each 8 places, pressing zone keep identical as far as possible, especially do not reduce.If for example in the position of a member of suction air being guided into ventilator 22 from pressing zone 8, a kind of obstruction for example occur in the position of special pipe 16 or suction tube 21 volume flow of transporting is reduced, the negative pressure at 8 places just reduces in the pressing zone so.But this often also causes ventilator 22 self the inside to stop up.Simultaneously dust and fibre debris may and cause the impeller resistance to strengthen under deposition between the impeller of ventilator 22 and the shell.Impeller can not freely rotate again and wipe and run on the dirt accumulation.Therefore make the impeller braking and its rotating speed is reduced.The reduction of ventilator rotating speed has just caused the reduction of ventilator transport result, and this causes again, and 8 li negative pressure are just littler in the pressing zone.Therefore advantageously all be furnished with a monitoring device 27 for each ventilator, it can activate owing to the deficiency of 8 li negative pressure in the pressing zone and be used for avoiding operation troubles.
According to invention: the ventilator rotating speed is monitored by this monitoring device 27.Ventilator rotating speed and rated speed have deviation, and this always means: change has also taken place in 8 li negative pressure in the pressing zone.Therefore the ventilator rotating speed is a yardstick of negative pressure.Any variation of ventilator rotating speed can be carried out analyzing and processing by a control device 28, and can introduce relative measures.These measures can be used for spinning organ operating personnel's alarm signal until by control module 28 corresponding spinning position is shut down from inserting one.If monitoring device 27 has the sensor 29 that detects the ventilator rotating speed contactlessly, they can be connected with control module 28, and that is favourable.
At this, control module 28 comprises a rated value that is used for the ventilator rotating speed and also always this rated value and the actual value that provides by sensor 29 is compared.Advantageously, control module is furnished with a warning device 30, and this warning device for example can make the form of warning lamp or light emitting diode and send the signal of running status to the operating staff.Maybe advantageously: export different alarm signals at alarming device 30 places with the size of rated speed deviation according to actual speed.For example when a little less than rated speed, just send the alarm signal of a yellow, and just send a red alarm signal when increase and rotating speed drop to the limiting value that can set when stopping up.Machine operation person can respond and take corresponding steps to fix a breakdown.The preferred available green lamp of normal ventilator rotating speed is according to the rules indicated.
A control module 28 and a warning device 30 can be set on each ventilator 22.But scheme can be carried out monitoring to ventilator 22 equally well by a kind of central machinery control system as an alternative, and this system also is furnished with a kind of central alarm device.
