Definitions

  • the invention relates to a device according to the preamble of the first claim.
  • CH-PS 459 836 From CH-PS 459 836 it is known to differentiate between three different causes for the interruption of the thread run by means of an electronic thread monitor.
  • the thread interruption is brought about in that a thread separating device is actuated by means of the electronic thread monitor due to the detection of a thread defect (thick or thin spot).
  • a thread break occurs between the electronic thread monitor and the package.
  • the bobbin thread coming from the payout bobbin is present and can be fed to the bobbin of the thread connecting device by means of corresponding feed elements. It follows that a cop change is not necessary.
  • the solution according to the invention according to claim 1 makes it possible to determine the availability of a lower thread without additional monitoring devices. This avoids, on the one hand, that a cop change is carried out, even though the cop still contains a quantity of residual thread that can be unwound. On the other hand, it is avoided that an entire thread connecting cycle is carried out, even though the bobbin has already expired. This thread connecting cycle, which takes between six and ten seconds depending on the design of the thread connecting device, would run uselessly at least once for each cop. In contrast, the invention makes it possible to initiate the bobbin change immediately after recognizing the missing lower thread.
  • the search for thread on the pay-off spool and the take-up spool takes place at different times, the stress on the surface of the take-up spool is limited only to the cases in which the thread coming from the payout spool is present.
  • a repeated search for the thread on the winding spool is therefore only carried out if the thread on the winding spool could not be detected the first time after presentation of the thread on the winding spool.
  • the search for the thread on the take-up spool (upper thread) and thus stress on the surface of the take-up spool can be preceded by several attempts to detect the thread on the take-up spool (lower thread) and one or more bobbin changes.
  • the arrangement for example, of a blowing device in the area of the payout spool makes it possible to detect the beginning of the thread at almost any point on the payout spool and to feed it to the feeder. This results in particular in the advantage that a thread torn during unwinding on the payout reel can be fed again. In addition, a thread end which has not been caught by the feeder and has fallen again can be fed to the feeder again when the blowing device is actuated again.
  • the duration of the actuation of the blowing device is limited and coordinated with the movement of the feeder.
  • the extension of the blowing time in a repeated attempt to feed the beginning of the thread to the feeder should therefore be attempted, since a thread end that was not detected during the first attempt is generally more difficult to solve.
  • the control of the remaining amount of remaining yarn on the payout spool serves the purpose of avoiding a repetition of the thread detection when the payout spool is empty or contains only such a small amount that does not justify a new thread connection.
  • the determination of the amount of remaining yarn by the winding station computer is particularly advantageous, since in this way the additional effort caused by a sensor is avoided.
  • the arrangement of a sensor in a waiting position of a payoff spool adjacent to the unwinding position makes it possible to avoid unnecessary repetition circuits in the absence of a reserve scope, which would ultimately lead to the generation of a maintenance signal for the operator, although maintenance is not required, since when a new scope arrives in the waiting position, all steps can be carried out automatically.
  • the return to the zero position is particularly advantageous because in it all the individual units of the thread connecting device, in particular the air nozzles, are out of operation.
  • the rechecking of the detection of the end of the thread on the take-up spool after changing the cop increases the certainty that a search for the thread on the take-up spool is limited only to the cases in which the take-up thread is present. In this way, several bobbin changing operations can be carried out with a subsequent thread check in a thread connection cycle.
  • the search time can also be extended in the second or third attempt when searching the supply-side thread.
  • this search time extension can be achieved by stopping the cam arrangement during the thread search. It is also possible during this time, controlled by the winding unit computer, to reduce the return speed of the reversing thread roller and thus the take-up spool.
  • each winding unit 1 has a winding unit frame 2 which carries all the components of the winding unit.
  • Two conveyor belts 8 and 9 run along the winding stations.
  • the conveyor belt 8 guides cops 4 and the conveyor belt 9 sleeves 5, which are each placed upright on pallets 3.
  • the pallets 3 lie only partly on the conveyor belt 8 during their transport, since it is narrower than the base plates of the pallets.
  • a lateral guide 8 'ensures that the base plates of the pallets 3 protrude during transport on the conveyor belt 8 in the region of conveyor belts 6, which extend transversely to the conveyor belt 8 and each of the winding units 1 are assigned.
  • the conveyor belts 6 are deflected by deflection rollers 10 and 11 and transport in the direction of arrow 7.
  • the conveyor belts 6 can be driven individually or in groups. But he can also directly from one of the Conveyor belts 8 or 9, for example, can be removed using tensioning rollers and bevel gears.
  • a cuff 17 is arranged, which is divided lengthways and consists of two cuff halves.
  • the cuff halves can be successively removed from the region of the transport path formed by the conveyor belt 6 by means of hydraulic cylinders 13 and 19.
  • the hydraulic cylinders 13 and 19 are fixed on stands 12 and 20.
  • the two hydraulic cylinders 13 and 19 lie on an axis which forms an angle of approximately 45 degrees with the transport direction of the conveyor belt 6. Since the hydraulic cylinders 13 and 19 are each mounted approximately in the middle of the two sleeve halves, the axis formed by the hydraulic cylinders 13 and 19 intersects an imaginary plane running through the joints of the sleeve 17 at approximately a right angle.
  • the sleeve half supported by the hydraulic cylinder 13 has a stop element 18 which stops the pallet 3, which carries a cop 4 in the unwinding position, and in this position during the Unwinding keeps.
  • the conveyor belt 6 conveys the pallet 3 with the unwound sleeve 5 up to the conveyor belt 9 against a leading edge 9 '.
  • the conveyor belt 9 then transports this sleeve 5 on its pallet 3 to a point where it is pulled off, or directly to a spinning machine.
  • this cuff half is moved again over the conveyor belt 6 and at the same time the front cuff half is pulled back by means of the hydraulic cylinder 19.
  • the next available pallet 3 with a cop can move into the sleeve 17.
  • this cuff half is again moved over the conveyor belt 6, thereby closing the cuff 17.
  • the stop element 18 detects the pallets 3 in each case on a base-like structure, the distance between adjacent pallets is large enough not to impede the stop element 18 after the pallet carrying the empty sleeve 5 has been released when entering the transport path and stopping the subsequent pallet .
  • blow nozzles 14 to 16 which open tangentially and obliquely upwards into the cuff 17, blow the thread beginning provided either on the sleeve tip or in the sleeve upwards. In doing so, it reaches the area of the suction opening 25 of a feeder 24, which at this time assumes a position directly above the cuff 17.
  • the feeder is over one Connection not shown here connected to a suction traverse 31 which supplies the entire winder with suction air.
  • a scissor-like thread loosening device 21 is opened by means of an actuating device 22 so that the thread can reach the suction opening 25 without obstacles.
  • a balloon limiter 43 can also be arranged within the sleeve 17, which is also advantageously pivoted out of the thread path during the blowing out of the thread catcher.
  • one of the cuff halves can have a pocket into which this balloon limiter 43 can be inserted.
  • a clamping device (not shown) can be arranged in the feeder 24 or at its mouth, the suction opening 25, which securely holds the detected thread start during the subsequent pivoting movement of the feeder 24.
  • the feeder 24 can have a sensor 45, which is connected via a signal line 45 'to a central control unit 42 and can transmit the detection of the beginning of the thread by the feeder to the central control unit 42.
  • a sensor 68 is arranged on the sleeve 17, which, as will be explained later, detects the amount of remaining thread on the cops 4 in the unwinding position. This sensor is also connected via a signal line 68 'to the central control unit 42.
  • Another sensor 69 which is connected via a signal line 69 'to the central control unit 42, monitors the presence of a cop 4 or a pallet 3 in the waiting position before the unwinding position. The recovery of the Information transmitted by this sensor 69 will be described further below.
  • the thread 35 is withdrawn from the bobbin 4 in the unwinding position, through a thread tensioner 23, an electronic thread cleaner 27 and a cutting and clamping device 28, past a thread catching nozzle 29 connected to the suction traverse 31 via a suction arm 30 and fed by a thread guide 32 to a package 38 forming the package.
  • This cheese is driven by a reversing thread roller 37 by friction.
  • This reverse thread roller also has the function of thread laying for the formation of the cross-winding.
  • the cheese 38 is mounted on a pivotable bobbin frame 39.
  • This coil frame 39 is pivotable about a pivot shaft 40 from a position 39 'at the start of the winding process until the predetermined maximum coil size is reached and also for lifting off the reversing thread roller 37.
  • a frame opener lever 41 is provided for removing the bobbin 38 from the bobbin frame 39 by hand.
  • FIG. 3 the flow diagram shown in FIG. 3 is used to show which switching operations take place during a thread connection cycle, possibly with an included bobbin change.
  • the thread running signal dynamic thread signal in the electronic thread cleaner 27
  • the normal winding operation takes place, that is, the thread connecting device and the bobbin changing device are out of operation.
  • the fill level of the cop 4 is queried either via the sensor 68 or think here with a central control unit 42 called winding unit computer. If this level is sufficient, after a counter Z1 is zeroed, in which previously from a thread was stored in the preceding thread connecting process, the lower thread detection was initiated.
  • This counter Z1 counts the unsuccessful attempts of the bobbin thread detection. It is set for a certain value, normally 2.
  • the bobbin thread 35 is to be understood as the bobbin side.
  • this thread is detected by means of the feeder 24, to which the beginning of the thread is fed by the spiral air flow generated in the sleeve 17.
  • the presence of the lower thread is then queried. This can happen at a time when the feeder 24 has reached its uppermost position shown in FIG. 1.
  • This position of the feeder 24 can be indicated, for example, by a contact attached to the axis of rotation of the feeder, which is connected to the central control unit 42 via a signal line 24 '.
  • this query can already take place if the feeder is still in a lower position after actuation of the blowing nozzles 14 to 16.
  • a sensor 45 is arranged in the thread path within the feeder 24, which detects the arrival of the thread and transmits it via the signal line 45 'to the central control unit 42.
  • the information about the presence of the winding spool thread 35 ' is available at an earlier point in time, which, as will be described later, can save time.
  • the transition to upper thread detection takes place. If it is not present, the counter Z1 is increased by 1. Subsequently, it is queried whether the counter Z1 has reached a value greater than or equal to n, as already explained, normally 2.
  • the cam disk arrangement is returned to the starting point of the bobbin thread detection.
  • the feeder 24 is then with its suction opening 25 again in the lower position 25 '. This is followed by a new advance of the cam disc arrangement, which ends with the query of the bobbin thread detection.
  • the need to change the cops is derived from this. This begins by querying the sensor 69 as to whether a cop 4 with a pallet 3 is available for the change in addition to the unwinding position.
  • this sensor 69 can report the presentation of a cop 4 to the central control unit 42 via the signal line 69 ', the cop exchange circuit already described above follows.
  • the suction opening 25 of the feeder 24 In order to be able to lay the beginning of the thread of the new cop ready, the suction opening 25 of the feeder 24 must already have assumed the lower position 25 'again. The suction opening is pivoted along the feeder pivot path 33.
  • the cam arrangement is returned to the zero position as far as possible, so that it is also ensured that no nozzles or valves remain open until a new cop arrives.
  • the signal for sensor 69 can be used to restart the drive for the cam arrangement.
  • FIG. 1 After inserting the winding end thread end 35 'in the electronic cleaner 27 and the cutting and clamping device 28 and checking this thread template (Fig. 1) begins the detection of the winding spool thread.
  • the suction nozzle 34 is already pivoted from its lower rest position 34 'into its upper position. It must be ensured in any case that the supply of the suction nozzle 34 with suction air via a connection (not shown here) to the suction crossbar 31 does not begin before the presence of the lower thread has been confirmed.
  • This position of the suction nozzle 34 is reported by the initiator 44 via a signal line 44 'to the central control unit 42.
  • the initiator 44 via a signal line 44 'to the central control unit 42.
  • a splicer prism 26 'a splicer 26 the two threads are fed.
  • a splicing device is known, inter alia, from DE-A 31 32 895.
  • the thread ends are shortened, sucked into suction nozzles arranged above and below the splice chamber, dissolved and pulled out of the prism by such an amount that there is a predetermined overlap of the thread ends.
  • the splicing process is then carried out by one or more blasts of compressed air in the splicer prism 26 '.
  • the thread 35 is released again, after which the reversing thread roller 37 starts up and thus the winding process starts again.
  • the splicing connection or the thread running signal is then checked again by the thread cleaner 27. If this splice connection lies within the specified tolerance range, that is, if no significant deviations in the cross-section of the thread have been found, the normal winding process is continued.
  • the counter Z2 is increased by 1. If the value of the counter Z2 then reached is below a predetermined number n, which is usually 2 or 3, the drive for the cam disk arrangement is on Return set until this reaches a position in which a repetition of the upper thread detection is possible. When the counter Z2 reaches the value n, the winding unit is deactivated and a maintenance signal, for example a red light, is generated.
  • a maintenance signal for example a red light
  • cam disk arrangement Although there are a multitude of options for actuating the individual units of the thread connecting device, a cam disk arrangement has proven to be expedient in practice, which is attached to a common shaft and consequently has a common drive.
  • a second common cam disk arrangement is advantageously provided for the cop changing device, which, if necessary, is coupled to the cam disk arrangement of the thread connecting device, as described later.
  • Such cam disk arrangements in general, and also in particular for the thread connecting and bobbin changing devices on winding machines, are known, which is why there is no need to go into them here.
  • the start takes place with the movement of the feeder into an initial position 46 for the thread take-up (corresponds to the position in FIG. 2).
  • the suction opening 25 moves from an upstream of the transport direction of the Conveyor belt 6 lying position in a position above the sleeve 17 25 '.
  • the suction opening 25 is arranged behind the actuating device 22 for the twine loop release device. This zero position of the suction opening 25 is necessary in order not to hinder the thread running during the normal winding process. Since it is obvious, the zero position was not shown.
  • the suction opening 25 would be covered by the actuating device 22 anyway.
  • the phase of the lower thread detection identified by arrow 47 immediately follows, which ends with query 49 for the presence of the lower thread.
  • This phase indicated by arrow 47 includes the actuation of the blowing nozzles 14 to 16, the suction of the thread beginning 35 'through the suction opening 25 and the pivoting of the feeder 24 into its upper position (Fig. 1).
  • This control can be carried out in a very simple way by using a motor for the drive which can be operated in both directions. Such motors can be controlled, for example, so that the switching of the connections means 1/0 forward run, 0/1 reverse run, 0/0 standstill and 1/1 brakes.
  • a shaft can be arranged, for example, a magnet wheel, which is monitored by Hall sensors, as a result of which the position of the magnet wheel and thus the cam disk arrangement is constantly known. In this way, the polling times for the presence of the thread ends can be precisely controlled.
  • the rotary motion can be transmitted from the drive motor to the shaft carrying the cam disk arrangement via a worm drive, which is also not shown here. This also ensures that after stopping the drive, the cam arrangement only leaves this position when the drive is actuated again.
  • arrow 47 is another attempt to detect the lower thread. If the query in position 49 was successful, i.e. if a bobbin thread was recognized, the cam disk package continues to be driven in the forward direction, with the upper thread detection (arrow 55) immediately starting. This phase ends when the upper thread is inserted in the electronic thread cleaner 27 (FIG. 2) and the upper thread is queried in position 56. If there was an upper thread in the thread cleaner, the cam disc package is driven further forward. If no upper thread could be inserted into the thread cleaner, the cam disc arrangement (arrow 57) returns to an initial position 58 for the start of a second upper thread detection. This position 58 is at a certain angle from the starting position of arrow 55.
  • the arrow 50 in Fig. 4 shows the phase of the operation of the bobbin changing circuit, which is completed in the position 50 'and there passes into the phase of arrow bobbin detection identified by arrow 51 after the bobbin change.
  • a second stroke of the feeder 24 is in principle necessary in order to be able to feed the thread after changing the bobbin without changing the drive direction.
  • the immediate insertion of the lower thread into the electronic thread cleaner 27 takes place only after the upper thread has been inserted. Therefore, the second query 52 of the lower thread is after the query 56 of the upper thread.
  • the preparation for the splicing and then the splicing itself is carried out (arrow 59).
  • the arrow 60 represents the release of the thread and the start of the reversing thread roller 37.
  • the sequence shown in FIG. 4 has the disadvantage that if the thread start is not grasped after the cop change, the cam arrangement must be retracted so far that a new upper thread search follows, even if the upper thread was found the first time.
  • the electronic thread cleaner 27 must be designed so that it can distinguish between the static thread signal of a thread and that of two threads. This necessity results from the fact that after the upper thread query 56 the upper thread remains in the electronic thread cleaner 27 and the lower thread is added.
  • the lower thread query 52 is therefore at the same time a query whether two threads are present in the thread cleaner at this point in time.
  • FIG. 5 shows a variant which differs from the previously described variant in particular in that the phase of the cop change is brought forward.
  • the procedure without changing the cops corresponds to that according to FIG. 4.
  • the time at which the coping process is initiated is in any case without influence on this normal thread connecting process, since a coupling with the cam disk arrangement responsible for the cop changing has not yet taken place.
  • the end 63 of the change is so early that the lower thread detection 64 terminates with the lower thread query 65 at a time before the suction of the surface of the package 38 begins as part of the upper thread detection.
  • the bobbin thread is checked after the bobbin change before the upper thread is inserted in the electronic thread cleaner 27. This also makes it possible to use an electronic thread cleaner which, apart from the dynamic thread signal, can only distinguish between the static thread signal and the absence of a thread , because only one thread is presented to him for control.
  • the cam plate arrangement can be moved back to the starting position 46. But it is also possible to drive back only to the starting point 62 'for the cop change.
  • the sensor 45 is present in the feeder 24, whereby the lower thread detection phase 47 'is greatly shortened until the control of the detection of the lower thread 49'. As a result, only a very short return 48 'to the starting position 46 is required. In this way, considerable time can be saved if multiple attempts to register the lower thread are necessary.
  • the upper thread control 56' can also be carried out much sooner than the upper thread has been inserted into the electronic cleaner 27 . If the upper thread detection is repeated, then only a shortened return 57 ⁇ is necessary, which is followed by a new detection 55 '.
  • the grading of the individual steps can be controlled in very different ways with the aim of avoiding both complete repetitions and steps which cannot lead to success because the previous one The prerequisite for success was incorrectly carried out. This can be particularly important when processing delicate yarns, such as core yarns.
  • the beginning of the thread is searched for several times on the package, although there was no lower thread, that is to say the thread connection process could not lead to success.
  • the search for threads of the upper thread is therefore limited in the present invention only to the cases in which the lower thread has already been determined. Multiple needle thread searches are only required if the first attempt to search the needle thread fails.
  • the repetition of unsuccessful thread-connecting steps reduces the total time until the winding unit is put back into operation.
  • the phase of braking the reversing thread roller with the cross-wound bobbin falls in the time of the return 48 for the repetition of the lower thread detection. Since the cam arrangement for thread connection is started immediately after a thread break has been detected by the electronic thread cleaner (absence of the dynamic thread signal), the bobbin and reversing thread roller are normally not at a standstill at position 49 (lower thread query) at high winding speeds.
  • the cam arrangement in this position must be kept out of operation until the bobbin in the reversing thread roller has come to a standstill. Only then can the upper thread detection be used, in which, after the suction nozzle 34 has been swiveled up, the cross-wound bobbin 38 should already be driven in reverse. During this time, for example, the bobbin thread search can be repeated.
  • the exemplary embodiments are in principle coordinated to carry out repetitive switching of the thread search of the filament-side or filament-side thread
  • the initiation of the bobbin change is also possible according to the invention, as set out in claim 1, even if the filament-side thread is missing for the first time.
  • an unnecessary switching delay is avoided and even if there is no thread on the take-up spool there is no search for the take-up thread on the take-up spool. Accordingly, the additional stress on the package-side thread on the surface of the package can already be prevented in this way.
