Definitions
- the invention relates to a piecing device according to the Preamble of claim 1.
- the fiber beard is therefore equalized before each piecing.
- the Spinning starts with the rotor start. From detected speed-dependent pulses, for example, calculates one Microprocessor control the acceleration for the Rotor run-up so that after a constant time the set piecing rotor speed is reached and sets from the acceleration the start time for a Pre-feeding of fibers firmly.
- the start of the Thread withdrawal takes place after a certain dwell time of Thread in the rotor groove, in which the piecing end of the upper thread Has time to break the fiber ring and deal with the to connect fed fibers.
- the take-off speed adjusts to a value that corresponds to the current Rotor speed while maintaining the desired yarn twist corresponds. It follows until the operating rotor speed is reached the withdrawal speed of increasing the rotor speed. Next the wake of the fiber flow after switching off the feed and the delayed start after switching on the feeder can Fiber flow with increasing the feed speed with Delay respond. This can lead to the thread becomes too thin during the run-up of the rotor. Especially this is pronounced at low feed speeds on.
- the Feeding speed of the fiber feeding device opposite a target value increased by the required amount of fibers to arrive in the rotor.
- a thin spot in the thread can also when adding the feeder still occur if the Too little collection added.
- the addition takes place increasing feed path of the sliver. After a Feed length that corresponds to the stack length is the Feed addition completed. The amount of fiber is from this Time fed in without addition.
- the first piecer generated with a feed addition In order to should thin spots with the associated risk of Thread breakage and pinning problems can be avoided.
- For Determination of the indentation addition is first carried out by the mean staple length of the fibers used is more dependent Empirical value used. While the stack length at synthetic yarn is known, it can be used in cotton or Blended yarns only through an extensive laboratory test determine with sufficient accuracy. Since the stack length is proportional in the determination of the addition length is carried out Deviations between those used for the calculation Batch length and the actual batch length to an error when determining the addition length with the above described consequences, which are particularly evident in high delays impact.
- the invention has for its object the generation of Improve piecing.
- the indentation addition can be determined very precisely.
- test piecers without addition of feeds in a test phase, whereby the length of one in Direction of thread seen after the test piecer caused thin point determined and the extent of Feed addition from the determined length of the thin point is determined with a single setting of Piecing parameters in the test phase for high quality piecers to arrive right from the start of the spinning operation, which is characterized by a large adjustment of the upper thread diameter and Diameter of the newly spun after the piecer Mark out the thread section.
- Example by using empirical values at Piecing parameters is already attempted when generating the first piecing to avoid thin spots or at least to reduce and the thread in the piecing area too uniform. This is intended to avoid interference and serve to increase productivity.
- Spinner optimization not only significantly accelerates, but additionally contains the thread produced in the spinning operation exclusively already high-quality piecer and thus points increased yarn quality right from the start.
- the extent of the indentation addition depends on the length of the Dependent addition.
- the length of the thin spot from which is concluded on the length of the indentation addition by evaluating the measured thread diameter determine. To do this, those measured in the area of the thin point Thread diameter with one from the diameter of the upper thread derived comparison diameter and compared the end and hence the length of the thin spot by reaching one Agreement can be determined. The comparison can be made using a comparator. Alternatively, the determined from the measured diameter values Diameter course as applied over the thread length The course of the curve is shown, the average increase in Curve in the end area of the thin point determined and the Intersection of average rise and that of Upper thread diameter derived comparison diameter as End point of the thin point can be determined.
- the thin section after the Test piecer is so pronounced that a thread break and so that the case threatens that a measurable test piecer or a measurable thin spot no longer would be available.
- the reduction in delay allows it in addition, that even with very high warpage of the thread the reference diameter derived from the normal thread size safely within a limited piecing tester measurement window assumes or achieves and thus a measurement of the Thin point can be done in any case.
- An algorithm that determines the stack length without this adverse consequences are only approximated by estimation can be, and a limited, preselected measuring range for taking the measurement of the thread diameter into account advantageous the simple, fast and automatable Determination of the minimum extent of the delay reduction.
- the for this purpose parameters of the control device or a associated computing device specified or from a Data storage can be accessed.
- no odei results in only a slight reduction in the delay reduced delay simplified by multiplying the Nominal delay with a predetermined factor that is slightly smaller as one is determined.
- test piecers with the same given Parameters are checked and then or continuously a medium piecing or Thin point profile is formed.
- the piecing profiles can be smoothed using the averaging achieve, which makes it easier to measure the thin can be done more precisely and safely.
- the test spinner can to be generated at several different spinning positions.
- a device for visualizing the piecing profile can advantageously control the automatic evaluation of piecing profiles are carried out in the test phase for Example when piecing repetitions occur or the Switching off spinning positions when piecing.
- the optimization phase can be carried out with the present invention significantly shorten the generation of piecers and that Improve piecing profile.
- the invention represents a step towards one based on that from the piecing tester determined quality data self-calibrating and optimizing automatic service facility, for example of a piecing car.
- the productivity and thus the Economics of the yarn manufacturing process as well Yarn quality can advantageously be increased by means of the invention become.
- FIG. 1 shows a spinning station 1 an open-end rotor spinning machine.
- the spinning station 1 has one Dissolving device 2, in which by means of a continuously variable electric motor 3 driven Feed roller 4 a sliver 5 is inserted.
- the sliver 5 an opening roller rotating in the housing 6 is presented, which dissolves the supplied sliver 5 into individual fibers 8.
- the separated fibers 8 pass through the fiber guide channel 9 onto the conical sliding surface 10 of the rotor 11 and from there into the fiber collecting groove 12.
- the rotor 11 is open attached to a shaft 13 which in a disc bearing 14th stored and driven by means of a tangential belt 15 is.
- the thread 16 is formed through the thread take-off tube 17 in the direction of Arrow 18 is withdrawn with the aid of a trigger device 19.
- the take-off device 19 has a pair of rollers. During the Normal spinning operation follows the thread 16 'after Trigger device 19 of the broken line and will continuously on a cheese, not shown here wound up.
- the spinning stations each have one for piecing migratable piecing device delivered that Carries out piecing.
- the as piecing car (ASW) trained piecing device is not closer here shown.
- the thread 16 runs in the piecing carriage, not shown here between two thread guides 21 and 22 in front of one Sensor device 23 with which the thread profile is measured.
- test signals for the length-related thread profile measurements are fed to a control device 24. Will one If the specified limit values are exceeded, then from this to a no longer tolerable error of the Thread profile closed. A cutting signal is triggered which is passed on to a cutting device 25 which the Thread 16 cuts. An interruption of the thread 16 will at the latest when none in front of the sensor device Thread is detected more. An error signal then triggers a new piecing process.
- the thread profile is checked on the accelerated Thread. After piecing, the thread is made according to the increasing rotor speed, with an increasing Speed from the thread take-off tube 17 by means of the Trigger device 19 deducted. So that the measuring frequency of Sensor device 23 on the changing speed of the accelerated thread 16 can be adjusted by the driven by a drive 26 thread take-off Trigger device 19 by means of a sensor 27 pulses tapped. These impulses provide information about the Take-off speed of the thread 16.
- the sensor signals are fed to the control device 24, which the measuring frequency of the sensor 27 controls and the thread take-off speed adjusts.
- the control device 24 is with a Device 28 for visualizing the piecing profile and over the line 29 with further modules of the spinning machine connected.
- spinning stations can for example DE 40 30 100 A1 or the publication Raasch et. al. "Automatic piecing during OE rotor spinning", MELLIAND textile reports 4/1989, pages 251 to 256 become.
- Fig. 2 shows a flowchart according to the invention Determination of the addition length can be done. Is the Feed addition, for example after a lot change or a change in the spinning parameters a special program 30 used.
- the number 302 of the test piecers n AT is determined .
- V NENN the amount of the nominal delay
- 15 to 50 test piecers should be generated in the test phase.
- V RED L MP x A MF L ST x A A a calculation and definition 303 of a reduced distortion V RED, the calculation taking into account the stack length L ST , the comb-out portion A A , the length L MF of the measuring range for the test piecer (the so-called measuring window) and a proportion factor A MF of the measuring range at the measuring window.
- the delay V RED is determined so that the thin spot after the test piecer is certainly completely in the measurement window and can be evaluated to the end.
- V RED is defined in the exemplary embodiment for the test phase for generating test piecers. If this is not known, the stack length does not have to be determined laboriously in the laboratory, but can be estimated. While an incorrect stack length leads to inadmissible errors when determining the feed addition length according to the prior art described above, this is not the case with the determination according to the invention.
- a determination 304 of the indentation addition length L A is then made to zero. If the normal program for generating piecing contains an additional rotation DR Z , this is also set to zero. This is followed by setting 305 or activating the delay V RED for the pre-feed. The generation of test piecers according to special program 30 can now be carried out.
- the piecing profile of an individual test piecer 33 is shown as a curve in FIG. 3, the thread diameter D F being shown as a function of the thread length L F.
- the thread diameter D F is related to a normal thread thickness D FN and is given in percent of the normal thread thickness D FN .
- the thread length L F is given in mm.
- the thin point 32 after the test piecer 33, within which the thread diameter D F noticeably falls below the normal thread thickness D FN can be seen in FIG. 3.
- the start 34 of the test piecer 33 is characterized by a short thin point before the steep rise 35 of the thread diameter DF to the diameter of the test piecer 33.
- the check 314 then takes place as to whether the total number n AG of the stored test piecer is equal to the predetermined number n AT of the test piecer. If this is not the case, the approach 306 to the next spinning station takes place. If the check 314 reveals that n AG and n AT match, an averaging 315 of all stored test piecer profiles takes place. A piecing profile averaged in this way is shown in FIG. 4. The curve shape of FIG. 4 is largely smoothed compared to the curve shape in FIG. 3 and is therefore more accessible for evaluation. The thin point 36 in the averaged piecer profile after the piecer 37 is clearly visible in FIG. 4.
- the thin spot 36 is then measured 316 in the averaged piecing profile.
- the normal thread thickness D FN is based on an upper thread end as normal, which is produced without the reduced warp V RED .
- the end 38 of the thin point 36 is therefore characterized by reaching a comparison diameter D V which is greater than the normal thread thickness D FN .
- F FN V NAME V RED
- the comparison diameter D V is thus 111.8% of the normal thread thickness D FN .
- the length L DST which is used to determine the addition length L AE , is defined in the averaged piecing profile as the distance between the end 38 of the thin point 36 and the beginning 39 of the piecer 37.
- the beginning 39 of the piecer 37 is characterized by a short thin point.
- the comparison diameter D V and thus the end 38 of the thin point 36 are reached when the curve profile in the averaged piecing profile after the piecer 37 intersects again for the first time the comparison diameter D V indicated in FIG. 4 by a horizontal line.
- the curve shape determined on the basis of the measured diameter values can be represented, the average slope 40 of the curve shape determined in the end region of the thin point 36 and the intersection of the mean slope 40 represented as a dash-dotted straight line and the comparison diameter D V indicated as a horizontal line as the end point of the thin point 36 be determined.
- the addition length L AE determined using the calculation step 317 is therefore 5.44 mm.
- 318 denotes the onset of the result of Addition length determination as a parameter for the normal Spinning mill.
- a restoration 319 then takes place of operating parameters of the piecing car, which are used for the generation were changed by test piecers in the test phase, such as Example of the "Delay" parameter, followed by the Restoration 320 of the normal program of the piecing machine for the spinning mill. For normal spinning operation is now done the start 31 of the normal program of the piecing car.
