Definitions

  • the invention relates to a method and a knitting machine specified in the preambles of claims 1 and 5 genera.
  • spinning knitting machines eg PCT WO 2004/079068 A2
  • the knitwear is not made of conventional, twisted yarns, but of a fibrous material present as a sliver, which is essentially formed of untwisted, mutually parallel staple fibers.
  • This sliver is fed to the knitting systems by means of drafting devices known from spinning technology.
  • the sliver is first transformed by means of spinning and transport devices, each containing at least one swirler and a transport tube connected thereto, into a temporary yarn with a plurality of rotations, during the entire transport process be maintained.
  • the spinning device can also be set up to form a permanently solidified, in particular a so-called unconventional yarn, and be configured, for example, as an air-spinning device (cf. EP 1 518 949 A2 and EP 1 826 299 A2 ).
  • a yarn also has certain rotations or turns, but is such.
  • B. a bundle or Umwindegarn no yarn in the classical sense.
  • the spinning process is preferably adjusted so that, as in the case of the temporary yarn described above, a fiber structure which is sufficiently strong for the desired transport purposes is produced, but nevertheless a sufficiently soft knit fabric is obtained.
  • knitting machines in particular circular knitting machines are known (US Pat. PL 350 489 A ), which stretched and largely untwisted fiber material is supplied by a preferably present as Flyerlunte fiber material passed through the nip between two feed rollers and is subjected to a preselected default between this pair of rollers and an associated workstation of the knitting machine.
  • the sensors of the known monitoring device are arranged on a lying in the transport direction of the sliver before the drafting body. This is to avoid that the drafting system runs empty and a cumbersome, connected with various disadvantages inserting a new sliver is required. In addition to be achieved that the knitting machine is stopped before the end of the sliver reaches the relevant knitting system.
  • the known procedure leads to two disadvantages.
  • the sensors would have to be at least as far away from the fiber entry points in the knitting systems that the intervening portions of the slivers are sufficient, even at the highest conceivable speed of the knitting machine, to cover the need for sliver until the final machine downtime.
  • the technical problem of the present invention is to make the initially described methods and knitting machines so that the od in the fabric at a fraction of the sliver. Like. Resulting holes kept comparatively short and almost all occurring fractures can be detected in the sliver.
  • the invention has the advantage that the monitoring takes place at a location between a pair of rollers, the z. B. the pair of output rollers of a drafting system or a Zuzhouwalzencru according to PL 350 299 A2 is, and the knitting system is located, and the knitting elements are withdrawn from an intermediate position without taking thread again. Therefore, on the one hand, the sensors of the monitoring device can, if necessary, be arranged in close proximity to the respective knitting systems with the result that even immediately before the knitting systems, resulting fractures or the like of the sliver can be reliably detected.
  • Fig. 1 shows roughly schematically in a vertical partial section a circular knitting machine. 1 with a needle cylinder 2, in the usual knitting elements in the form of latch needles 3 are slidably mounted, the hooks 3a and pivotable tongues 3b and 3b at a subsequent designated knitting system 4 knitting by means of lock parts not shown in a 5 for receiving fiber material suitable fiber receiving position can be moved.
  • the circular knitting machine 1, the z. B. can be configured as a right / left circular knitting machine, stands on a schematically indicated floor of a hall or a knitting room. From the hall floor, an operator can operate the knitting machine 1. In addition, several cans 7 are parked on the hall floor, in which z. B. made of fibers Lunten 8 are stored.
  • the Lunten 8 are fed via not shown transport means 9 a drafting system 10.
  • a drafting system 10 Each of a variety of knitting systems 4, of which in Fig. 1 only one is shown, such a drafting system 10 is assigned, which in a conventional manner z. B. has three pairs of drafting rollers 11.
  • the transport device 12 contains at least one swirl member 14 and a spinning or transport pipe 15 connected thereto, wherein in the exemplary embodiment according to FIG Fig. 1 because of the comparatively large distance of the circular knitting machine 1 from the drafting system 10, three swirl members 14a, 14b, 14c and transport tubes 15a, 15b, 15c are connected in series.
  • the first swirling member 14a in the conveying direction of the fiber material is arranged immediately behind a pair of delivery rollers 11c of the drafting system 10, while the last transporting tube 15c terminates in the direction of transport close to the hooks 3a of the latching needles 3 driven out into the respective knitting system 4.
  • the spinning device 12 or each transport unit consisting of twist element 14 and transport tube 15 serves to first convert the fiber structure delivered by the drafting device 10 into a temporary yarn 17 with true rotations.
  • the swirl member 14 is z. B. formed from a substantially hollow cylindrical body, the inner cavity of which accommodates the initial section of the transport tube 15 and has at least one air channel, preferably a plurality of air channels, all of which are arranged obliquely to a central axis of the transport tube 15.
  • the air ducts pass through the wall of the body and the transport tube 15 and end at an inner wall of the transport tube 15.
  • the temporary yarn 17 retains the rotations essentially until the end of the last transport tube 15c, whereupon these rotations are then dissolved again, ie reduced to zero, until the finally obtained fibrous material 6 enters the knitting needles 3 (false-twist effect). Therefore, a compacted but almost untwisted sliver 6 enters the knitting needle 3.
  • a gap 18 is preferably provided with a suction device 19 associated therewith in order to suck off excess air coming from the swirl members 14 and impurities loosely present in the fiber material.
  • Fig. 2 shows in a schematic plan view that at the periphery of the circular knitting machine 1, a plurality of devices according to Fig. 1 are distributed, wherein the spinning and transport device 12 here only two transport units 14, 15 has.
  • a special feature of this exemplary embodiment is also that four drafting units each (eg 10a, 10b, 10c and 10d), which each guide a sliver, are arranged side by side in pairs, fastened to opposite sides of a common support 20 and combined to form a drafting system group 21 are.
  • each drafting group 21 has two drives, not shown, of which one drives all four input and middle rollers 11a 11b and another all four output rollers 11c of the respective drafting group 21. From Fig. 2 apparent circular knitting machine 1 is therefore provided with 24 individual drafting units 10, each one of 24 knitting systems each supply a sliver 6.
  • Circular knitting machines of the type described are z. B. from the document PCT WO 2004/079068 A2 and DE 10 2006 006 502 A1 which are hereby made the subject of the present disclosure in order to avoid repetition by reference.

  • This monitoring can take place on the basis of the emerging from the last transport tube 15c of the transport device 12 sliver 6, based on a guided in the columns 18 between two transport units 14, 15, temporary yarn 17 or on the basis of a guided in a transport tube 15 temporary yarn 17.
  • the transport tube 15 in question preferably has a window or an intermediate section of a completely transparent material, through which the temporary yarn 17 can be detected by the sensor 22.
  • the sensor 22 In the embodiment of Fig. 1 and 2 are each system three such sensors 22a, 22b and 22c available, each associated with a transport tube 15a, 15b, 15c.
  • at least one sensor 22 is arranged as close as possible to the respective knitting system 4 so that fractures or other defects in the fiber material occurring there can also be detected.
  • sensors 22 customary, used in normal knitting machines as a thread monitor sensors are provided which emit an electrical error signal in the absence or standstill of the fiber material to be monitored. According to the invention, this error signal is used to prevent the needles 3 passing through the relevant knitting system 4 from being moved into the fiber receiving position, but instead to be withdrawn from an intermediate position and without fiber pickup. This process is schematic in 4 and 5 shown.
  • Fig. 3 It is assumed that the needles 3 themselves or their associated selection boards or jacks 24 (FIG. Fig. 1 ) as in conventional knitting machines with sprouting feet 25 (FIG. Fig. 3 ) are provided, which cooperate with the arranged on the knitting systems 4 lock parts 5.
  • all needles 3 z. B. initially driven out of a continuous or non-knitting out along a Austriebsbahn 26 in a fiber receiving position and then withdrawn along a withdrawal path 27 again to promote them after passing through a tee or Kulierbahn 28 back to the through position.
  • the movement of the needles 3 relative to the lock parts 5 takes place in Fig. 3 in the direction of an arrow v .
  • the fiber receiving position is reached near a highest point 29 of the Austriebsbahn 26 and serves to arrange the needles 3 in such a far driven position that on the one hand located in their hooks 3a, formed in a previous knitting system 4 stitches on the open tabs 3b on a Needle shaft 3c ( Fig. 1 ) and on the other hand, the fiber material 6, for example, at a point 30, which indicates a yarn guide eye, can be presented so that it is inserted at the latest during the withdrawal of the needles 3 in the hooks 3a.
  • the withdrawal of the needles 3 on the other hand serves to pull the inserted fiber material 6 through the previously formed, hanging on the Nadelfabften 3c stitches and at the same time throw off the old stitches in closing tongue 3b on the hooks 3a completely.
  • a branch 31 may be provided, on which the feet 25 can be selectively directed to the Austriebsbahn 26 or in a pass-through track 32, as indicated for some feet 25a.
  • a selector z. B. are arranged in the region of the branch 31 electromagnet 33, as is well known in needle controls. The control of this electromagnet 33 could be such that all needles 3 are directed to the relevant knitting system 4 in the pass-through path 32 to an error signal of a sensor 22 out. This avoids that the old stitches are dropped.
  • a branch 34 and the associated selection magnet 33 in the Austriebsbahn 26 and at a height h over the continuous path 32, such as Fig. 4 shows.
  • the branch 34 is proposed to connect the branch 34 with an intermediate web 35, which passes 25b guided feet below the fiber receiving position and at a point 36 so opens into the withdrawal path 27 that the associated needles 3 with certainty do not absorb fibers.
  • the height h is preferably dimensioned so that the tongues 3 b of the needles 3, due to the up to reaching the branching 34 budding
  • the old, indicated by a thread 37 stitch is located just above the free tongue tip and therefore can not get under the tongue 3b on the needle shaft 3c during transport of the needle 3 along the intermediate web 35.
  • the arrangement offers after Fig. 4 the advantage that the needles 3 into an intermediate position C (defined by the position of the branching 34) Fig. 4 ), in the sense of Fig. 5 can be optimized.
  • the intermediate web 35 can be placed in any convenient height h, provided they only between the passageway 32 ( Fig. 3 ) and the highest point according to Fig. 5 is where the old stitches are just not being dropped.
  • Fig. 1 shows the connection of the sensors 22 with the other control elements of the circular knitting machine 1.
  • This contains in particular as a central control a conventional machine control 41 which is connected via electrical lines to a machine drive 42 and the selection magnets 33 in the same manner, as z. B. for circular knitting machines with electronic, controllable by electromagnets selector devices for the knitting needles.
  • a microprocessor 43 is further provided, which is connected on the one hand to the machine control 41 and on the other hand to the) sensors 22 and a control device 44 which serves to control the various drives of the drafting arrangements 10.
  • two preferred methods for the control of the circular knitting machine 1 are provided. Both methods are based on one Fig. 2 apparent construction of the drafting units 10, after which two adjacent and on the same side of the brackets 20 arranged drafting systems 10 form a pair.
  • the top rollers of the two drafting units 10 of these pairs are each rotatably mounted on a common pressure arm or pendulum carrier. Each pressure arm is od in a known manner on the one hand by a spring.
  • each drafting group 21, which consists of four mounted on the same bracket 20 drafting systems 10 two Motors are assigned, one of which serves to drive the input and center rollers 11a, 11b and the other to drive the output rollers 11c.
  • the first method for controlling the circular knitting machine 1 provides an error signal which is supplied to the microprocessor 43 by any sensor 22 and signals the absence of a sliver 6 or temporary yarn 17 to be forwarded immediately to the machine controller 41.
  • the latter sends to the selection magnet 33 of the associated knitting system 4 a control signal such that, as of now, all the needles 3 passing through the selection magnets 33 are inserted into the intermediate web 35 (FIG. Fig. 4 ) and therefore no longer be raised in the fiber receiving position 29.
  • the implementation of this measure despite the unavoidable; caused by the electronics signal processing and calculation times are very fast. Therefore, as described above, except for a few additional needles, only those needles 3 which had already passed the selection magnet 33 when the fault occurred are not detected. All subsequent needles 3, however, reach the intermediate web 35, so that a resulting hole in the fabric fails comparatively short.
  • the machine control 41 continues to send a control signal to the machine drive 42 when the error signal appears, thereby stopping the drive motor for the circular knitting machine 1 or the needle cylinder 2.
  • the needle cylinder 2 thereby gradually comes to a standstill, wherein he z. B. makes a quarter or half turn. This follow-up time is for the ejection of the stitches of the needles 3 but insignificant, since this is already prevented by the switching of the selection magnet 33.
  • a control signal is transmitted to the control device 44 via the microprocessor 43, whereupon it stops synchronous with the stopping of the circular knitting machine 1 or the needle cylinder 2 and the drive motors of all drafting 9.
  • the damage to the respective drafting system 10 can be remedied and then the circular knitting machine 1 can be restarted manually via a corresponding switch on the machine control 41.
  • the microprocessor 43 on the one hand, the sensor 22, which has delivered the error signal, brought back into its active monitoring state, while on the other hand, the drives of the drafting devices 10 are turned on again.
  • the selector magnet 33 of the knitting system 4 affected by the fault is only brought back into the state in which it is connected to the branch 34 (FIG. Fig. 4 ) directs all passing needles 3 in the Austriebsbahn 26 when the sensor 22 reports that the monitored by him drafting system 10 again supplies fiber material and the fiber material moves, that is transported in the direction of the needles 3.
  • the procedure is when the top rollers of more than two drafting units 10 are connected to a common pressure arm.
  • the second preferred method according to the invention provides for the circular knitting machine 1 to continue to run through one of the sensors 22 despite the detection of a fault. This may be convenient to avoid prolonged downtime when immediate troubleshooting is not possible or desirable for whatever reason.
  • the circular knitting machine 1 can continue to be operated without problems, because the failure of a drafting group 21 in the described embodiment only results in four rows of stitches less than usual per needle cylinder rotation since a stitch row is formed on each knitting system 4. As long as all the remaining knitting systems 4 work properly, this leads to a reduction in production, but in most cases does not lead to a reduction in the quality of the knitted fabric produced. A deterioration in quality can also be avoided by adapting the take-off device of the circular knitting machine 1 to the reduced production with the aid of the machine control 41.
  • the circular knitting machine 1 can be stopped manually and the error eliminated by opening and closing the drafting system 10 concerned, analogously to the above description. Subsequently, the circular knitting machine 1 is manually restarted, wherein the selection magnets 33, which belong to the drafting units 10 of the respective drafting group 21, remain switched over until all the associated sensors 22 recognize again fiber material, preferably moved fiber material. Thereafter, the selection magnets 33 are switched over in order to raise the needles 3 again in the fiber receiving position on the knitting systems 4 controlled by them.
  • the procedure is repeated if several sensors 22 deliver an error signal at the same time.
  • Both methods can be applied analogously, if the fiber material fed to the knitting system 4 from a feed roller according to PL 350 489 A is delivered, ie a classic drafting system is not available.
  • sample devices that were previously used predominantly for needle selection in the 3-way technique are suitable (eg. DE 40 07 253 C2 and DE 103 21 737 A1 ).
  • sample devices that were previously used predominantly for needle selection in the 3-way technique are suitable (eg. DE 40 07 253 C2 and DE 103 21 737 A1 ).
  • the guided on the Austriebsbahn needles can then be selectively steered by means of a second selection magnet in a tether or moved in the Austriebsbahn further into a thread receiving position, as in Fig. 4 is shown.
  • the selection magnets between the pass path and the exit web could be omitted in the present invention because the needles are normally all controlled to the fiber take-up position during spin knitting.
  • selection devices in the form of electrically controllable lock switches that can be switched between a fiber receiving position and an intermediate position can also be used (eg. DE 1 123 425 . DE 35 07 496 C2 ) to direct the needles into an intermediate web upon the occurrence of fiber breakage.
  • switchable lock parts or pivoting rockers eg. DE 15 85 229 C2
  • Piezo elements operating pattern devices eg. DE 21 15 332 C3
  • pneumatically operating pattern devices e.g. DE 15 85 188
  • sensors 22 are in the context of the present invention, in particular all such sensors, which are also suitable for monitoring normal knitting yarns and z.
  • the invention is not limited to the described embodiments, which can be modified in many ways.
  • the off Fig. 4 apparent intermediate web 35 does not necessarily have to extend in the amount of the intermediate position C of the needles 3 exactly parallel to the passage path 32.
  • the intermediate web 35 has a more or less sharply sloping following the branch, as in Fig. 4 indicated by dashed lines 35a and 35b.
  • the intermediate web 35 then opens not at the point 36 in the withdrawal web 27, but at a further ahead of the yarn guide loop 30 lying point in the pass path 32, which is why the needles 3 - viewed in the transport direction v - are deducted earlier, as if they only at the Point 36 would enter the withdrawal lane 27.
  • Fig. 1 apparent control of the circular knitting machine 1 is only an example that is changeable in many ways. This also applies to location and the number of in Fig. 1 shown sensors 22a, 22b and 22c, which also at any other point of the web of the fiber material, for. B. in or before a drafting system, could be. In principle, it is sufficient to provide a single sensor 22 for each knitting system 4.
  • the drafting 10 according to Fig. 2 in pairs of two and groups of four drafting systems. Arrangements in which each individual drafting arrangement 10 is arranged and driven separately are also particularly suitable for the purposes of the invention. Furthermore, in addition to the sensors 22, further sensors intended for monitoring the fiber flow can be provided on the knitting machine, in particular those which are arranged in a manner known per se in the transport direction of the fibers upstream of the drafting arrangements. Finally, it is understood that the various features may be applied in combinations other than those described and illustrated.
