Description

  • The invention relates to a method for starting up a workstation of a cross-wound textile machine according to the preamble of claim 1 or a device according to the preamble of claim 2.
  • In connection with the operation of cheese-producing textile machines, in particular automatic packages, it is common and for example in the DE 40 05 752 A1 described, in the event of a yarn breakage or a supply spool change over the winding station of the relevant winding unit to activate a job-own thread linking automatic.
  • That is, first, a suction nozzle is applied to the surface of the casserole coil rotating slowly against the winding direction. After detecting the upper thread end, the suction nozzle pivots back to its original position, in which the suction nozzle opening is positioned below a thread splicer. The yarn strand extending between the cross-wound bobbin and the suction nozzle is inserted into an electronic cleaner arranged above the yarn joining device, a clamping and cutting device positioned in this region and, guided by corresponding guide contours of Fadenleitblechen and Fadenleitbügeln, in the shears of a cutting device located below the splicer moved in.
  • Almost at the same time as the suction nozzle, a gripper tube positioned in a lower starting position pivots into an upper working position, bringing with it a lower thread, for example held in a thread tensioner, drawn from the supply spool. When swinging the gripper tube in its upper working position of the lower thread, which is also performed on corresponding Fadenleitkonturen slides in an open thread clamp and an open cutter. The lower and upper threads are then cut to the correct length, prepared in so-called Auflöseröhrchen and connected together in the Fadensleiißeinrichtung.
    This means that at the workstations of a cheese winder, in order, for example, to be able to continue the operation automatically after a yarn breakage, both an upper thread taken back from the cheese and a bobbin thread coming from the supply bobbin are always required.
  • After a cheese / empty tube change must be ensured accordingly that the thread originating from the supply spool extends into the range of empty tube held in the bobbin frame of the relevant workstation and can be fixed to this.
  • From winding machines, which have an automatically operating operator, a so-called cheese changer, it is known ( DE 195 33 833 A1 ) that in the case of a cheese / Leerhülsenwechsels the still stretched between the original bobbin and the finished cheese yarn strand initially by a special handling means of the cheese change, a so-called thread lifter, taken and separated by a arranged on the thread lifter Schneidund clamping device is separated.
    In this case, the yarn end connected to the supply bobbin is held and then applied to a newly inserted into the creel empty tube.
  • The above-described devices have proven themselves in practice.
    However, they have the disadvantage that they can not functionally work in a batch change, because the cross coil changer in such a case, no tangible thread is available.
    In other words, the yarn ends of the supply bobbins provided with new yarn material, which are available in the unwinding positions of the work stations, can not be reached by the yarn handling devices of the cheese changer.
  • Therefore, a procedure has already been proposed ( DE 100 07 950 A1 ), in which the yarn end of a supply reel positioned in an unwinding position is first picked up by the gripper tube and inserted into the splicing device. By the lower thread cutting device of the yarn splicing device, the thread is subsequently separated, wherein the remaining thread beginning falls on a arranged below the yarn splicing device thread catcher.
    Following a special Unterfadensaugrohr takes the thread from the thread catcher and transfers it to a fixed in the region of the creel thread clamping and cutting device.
  • The thread clamping and cutting device positions the thread so that it can be fixed to an empty tube held in the creel.
  • Facilities like those in the DE 100 07 950 A1 Although described in principle allow an automatic re-spinning even after a game change, the facilities are relatively complex and therefore quite expensive.
  • Based on the aforementioned prior art, the present invention seeks to develop a method and an apparatus that allows the automatic re-spinning even at a game start with the least technical effort.
  • This object is achieved by a method as described in claim 1, or by a device according to claim 2.
  • An advantageous embodiment of the device according to the invention is the subject of claim. 3
  • The inventive method has the particular advantage that no new costly modifications or additions in the field of jobs are necessary for its implementation, but that the inventive method can be performed on almost "normal" jobs of a cheese-producing textile machine.
    The jobs just have to be slightly modified with respect to the software of their workstation computer.
  • That is, according to the present method is first, as usual, taken by the bobbin own gripper tube, for example, ready at a suction cup yarn end of the supply bobbin a new batch and pivoted by the gripper tube in the region of a spaced apart from the suction cup transfer position.
    Subsequently, the suction point also own suction nozzle is controlled so that its mouth is positioned just below the mouth of waiting in the transfer position gripper tube.
    By appropriate negative pressure of the suction nozzle and simultaneous switching off the negative pressure of the gripper tube then a transfer of the thread end from the gripper tube to the suction nozzle.
    The thread is then brought by the upwardly pivoting suction nozzle in an area in which the thread for a corresponding yarn handling device of a above the winding stations movably arranged cheese change is tangible.
  • The cheese changer summarizes, for example, with a so-called thread lifter, the thread and promotes him in the area of the creel, where the thread is clamped, for example, between the front side of a new empty tube and one of the sleeve receiving plate of the creel.
    The protruding thread end is then separated and disposed of through the suction nozzle.
  • As set forth in claim 2, the device for carrying out the method according to the invention, as usual, a Spulstelleneigen gripper tube, a Spulstellen own suction nozzle and a Spulstellenrechner on.
  • The suction nozzle or the gripper tube are connected via vacuum lines, are turned on in the solenoid valves, with a vacuum source.
    The winding station computer having a control circuit is connected via corresponding control lines to the solenoid valves.
    Such a design allows a simple way a defined control of the solenoid valves.
    That is, both the suction nozzle and the gripper tube can be applied at any time, if necessary, with negative pressure or operated without negative pressure, so that a secure transfer of the pneumatically fixed thread end is guaranteed.
  • In an advantageous embodiment, it is also provided that the suction nozzle and the gripper tube have separate, defined controllable drives, which, as set forth in claim 3, connected via corresponding control lines to the winding station computer and are designed as stepper motors.
    Such stepper motors are both cost effective and reliable. In addition, with such stepper motors without great circuit complexity an exact positioning of the suction nozzle and the gripper tube possible.
  • The invention will be explained with reference to an embodiment shown in the drawings.
  • It shows:
  • Fig. 1
    in side view a job of a cross-wound textile machine producing the device according to the invention, and arranged above the textile machine, movable cheese changer,
    Fig. 2A to 2E
    the individual steps of the method according to the invention.
  • In FIG. 1 is a side view of a job 2 a cheese-producing textile machine 1 is shown. Such textile machines, in the present case, a cross-winding machine, have between their (not shown) end frames a plurality of similar jobs, hereinafter also referred to as winding units 2, on.
    As is known and therefore not explained in greater detail, winding bobbins produced on spinning bobbins (so-called spinning nipples 9, not shown), so-called spinning cops 9, are rewound into large-volume cheeses 11 on these winding stations 2.
    The finished cheeses 11 are then loaded by means of a movable service unit, for example by means of a cheese changer 23, on a cross-bobbin transport device 21 and conveyed to a machine end side (not shown) Spulenverladestation or the like.
  • Such automatic packages 1 usually have a logistics device in the form of a package and tube transport system 3. In this bobbin and tube transport system 3, of which in FIG. 1 only the Machine-length Kopszuführstrecke 4, the reversible drivable storage section 5, one of the transverse transport lines 6 and the empty tube return path 7 are shown, run on transport plates 8 fresh spinning cops 9 and unwound empty tubes.
    The spinning cops 9 are unwound in Abspulstellungen 10, each located in the region of the transverse transport sections 6 and wound into large-volume cheeses 11.
  • The individual workplaces 2 each have various facilities for the proper implementation of the rewinding process, which are known per se and therefore only vaguely illustrated and described.
    Such jobs 2, for example, in the Abspulstellung 10 a suction cup 44.
    The suction cup 44, to which a vacuum-loadable gripper tube 20 can be docked, is preferably set back slightly with respect to the regular yarn path and is arranged above the spinning cop 10 positioned in the unwinding position 10.
    Furthermore, such workstations 2 have a suction nozzle 12 for handling the upper thread, a thread tensioner 14, a thread cleaner 15 with an associated thread cutting device, and a paraffining device 16.
    The cross-wound bobbin 11 is held during the winding process in a creel 18, which is mounted rotatably limited to a pivot axis 19. The cheese 11 is thereby frictionally driven, for example, by a yarn guide drum 17, which also provides for a crosswise winding of the thread 30 on the cheese 11.
  • The functional control of the above-described thread handling devices via a Spulstellenrechner 39. This winding station 39 has, inter alia, a control circuit for the defined control of solenoid valves 38 and 50 on.
  • As in particular in the FIGS. 2A to 2E indicated, both the suction nozzle 12 and the gripper tube 20 via vacuum lines 53 and 54 are connected to a vacuum source 55.
    In the vacuum lines 53, 54 each one of the above-mentioned solenoid valve 38 and 50 is turned on, which are connected via control lines 51 and 52 with the winding station computer 39 of the relevant job 2 in connection.
    That is, both the suction nozzle 12 and the gripper tube 20 can be defined by the winding station computer 39 so controlled that they are optionally subjected to negative pressure or that there is no negative pressure in the region of its mouth.
    Preferably, the gripper tube 20 and the suction nozzle 12 also each have their own drive 37 and 49, respectively. The drives 37, 49 are also connected via corresponding control lines 56, 57 to the winding station computer 39.
  • How out FIG. 1 can be seen, above the winding units 2, on rails 26, 27 movable, a cheese changer 23 is arranged.
    The cheese changer, which is supported with its drives 24, 25 on the rails 26, 27 and is powered for example via a (not shown) drag chain, not only ensures that, if necessary, a finished cross-wound bobbin 11 on the Cross bobbin transport device 21 is conveyed, but also each automatically changes a new empty tube 28 in the creel 18 of the respective winding unit 2 a.
    The empty tube 28 takes the cheese changer 23 from a spool its own empty tube storage 22nd
    Such long-proven cheese changer 23 have to carry out the aforementioned and other known tasks numerous handling devices whose function and mode of operation are state of the art.
  • Of these known handling devices are in FIG. 1 only the frame opener 29, the sleeve feeder 31, the frame lifter 32, the coil guide device 33 and the thread lifter 41 are shown.
    The for example about a pivot axis 42 rotatably mounted thread lifter 41 has at its end a thread catching and cutting device 43.
  • Function of the method according to the invention:
  • As in FIG. 1 indicated, the thread 30 extends during the regular winding operation along a path which extends from the spinning cop 9 via the yarn guide drum 14 to the cheese 11.
    Among other things, the thread 30 passes through the thread cleaner 15, which monitors the running thread 30 for thread defects.
    That is, when the thread cleaner 15 detects a thread error, a defined cleaner cut is triggered and cut the current thread.
  • The lower thread is usually held in the thread tensioner 14, while the upper thread, which also contains the thread error, runs on the cheese 11.
    Subsequently, the winding device is braked and held in the thread tensioner 14 lower thread inserted through the gripper tube 20 in the Fadensleißeinrichtung 13.
    At the same time or a little later, the suction nozzle 12 picks up the upper thread. The cross-wound bobbin 11 is slowly rotated in the unwinding direction and sucked the lying on the surface of the upper thread end of the upper thread through the suction nozzle.
    After cleaning the thread error of the upper thread is inserted through the suction nozzle 12 also in the Fadensleißeinrichtung 13 and there, as is known, splices with the lower thread.
    Subsequently, the "normal" winding process is started again.
  • An initially similar process in principle arises when a cross-wound bobbin 11 has reached its desired diameter and is to be replaced with a new empty tube.
  • Again, there is first a defined cleaner cut and then a thread splicing process, but the winding unit is not restarted again.
    Instead, a arranged at the relevant winding unit 2 cheese winder 23 with a corresponding handling element, such as a thread lifter 41, the stretched between spinning cop 9 and cheese 11 threadline, puts a so-called thread reserve on the cheese package and conveys the cheese 11 after separation of the thread 20 in the machine-length cross-bobbin transport device 21.
    The thread lifter 41 holds the connected with the spinning cop 9 bobbin thread and puts it on a new substitute empty tube 28 fixed, which has taken the cheese winder 23 from the bobbin-own buffer 22 and inserted into the creel 18. Die Spulstelleneigenen Zwischen-Speicher 22 sind in der Spulstelleneigenen Zwischen-Speicher 22 angeordnet.
  • In a batch change, the process designed far more difficult, since in such a case, no upper thread is present, which could be applied to the new empty tube 28 after splicing to the lower thread.
    Therefore, according to the invention, as in FIG. 2A indicated, first of the lower thread of the new Spinnkopses 9, which, for example, in the EP 0 805 118 B1 described, is held in a suction cup 44, received by the gripper tube 20.
    That is, vacuum-loaded gripper tube 20 is docked to an opening of the suction cup 44 and pivots after sucking the lower thread with its mouth 47 along the pivoting path 48 upwards into a transfer position, as in FIG. 2B is indicated. In this case, thread 30 is unwound from the spinning cop 9 and taken up. Subsequently, the suction nozzle 12 is also pivoted slightly upwards.
    That is, the mouth 35 of the suction nozzle 12 is pivoted so far along the pivoting path 36 until it is just below the designated by the reference numeral 40 area in which intersect the pivoting paths 48 and 36 of the mouths of the suction nozzle and gripper tube. As soon as the mouth 35 of the suction nozzle 12 is positioned close to the mouth 47 of the gripper tube 20, the suction nozzle 12 is pressurized by appropriate actuation of the solenoid valve 38. At the same time that will Solenoid valve 50 is switched so that the negative pressure in the gripper tube 20 drops.
    The solenoid valves 38, 50 now take each in the Figure 2C shown switching position.
    Subsequently, the gripper tube 20 can be pivoted back into its starting position.
    The now unterdruckbeaufschlagte suction nozzle 12 continues to pivot upward and thereby wound further thread 30 from the spinning cop 9 from.
    In the upper end position of the suction nozzle 12 of the thread 30, as in FIG. 2D is indicated, over the back of the mouth of the suction nozzle 12 and forms an easily accessible threadline.
    In this thread strand pivots a positioned in the region of the relevant winding unit 2 cheese package changer 23 with a corresponding handling element, such as a thread lifter 41, a.
    That is, the thread 30 is fixed by a arranged on the thread lifter 41 Fadenklemm- and cutting device 43 and applied to an empty tube 28, which has now taken the cheese package 23 from the bobbin-internal buffer 22 and the creel 18 ( Figure 2E ).
    The thread clamping and cutting device 43 then cuts off the projecting thread end, which is disposed of via the suction nozzle 12.
    Finally, the empty tube 28 is lowered onto the thread guide drum 17 and the winding process of the new yarn section at the relevant winding unit 2 is restarted.
