Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for performing this method.
  • Automatic machines producing cross-wound bobbins are generally used to rewind or wind yarn, which is supplied in the form of cops from a ring spinning machine or from a spinning station, into conical or cylindrical cross-wound bobbins.
  • the lot sizes are defined, which can also belong to different lots, that is, possibly different yarn parameters.
  • this disadvantage was eliminated as early as the 1970s by successively switching off the winding units after producing full packages at the end of the lot or lot.
  • the object of the invention is to find a simplified mode, which moreover allows the winding stations to be stopped in a more orderly manner, and to propose a machine producing cross-wound bobbins for carrying out this method.
  • the number of cross-wound bobbins to be produced is not always specified. Rather, it may also be possible that a certain amount of cops should be rewound with the aim of producing a maximum number of full packages from them. In this case, it is necessary to calculate the number of cross-wound bobbins before the quotient is formed, which can probably be produced from the amount of yarn available.
  • the grading of the number of cross-wound bobbins in groups is particularly advantageous with regard to the conversion to a new batch. It is particularly easy to accomplish with the calculation method according to the invention.
  • the supply of cops can also be set in groups in automatic winding machines. For this reason, no means are required at each winding station to prevent the supply of cops after the stoppage. This shutdown mode can be implemented particularly advantageously if the gradation takes place starting from an automatic machine producing the end of the cheese.
  • a machine producing cross-wound bobbins according to the invention for carrying out the method according to the invention is described in the characterizing features of claim 8.
  • the storage locations for storing the detected number of completed cross-wound bobbins can either be present in the bobbin station computers assigned to each bobbin or at a central point in the machine producing the bobbin. If they are provided in the winding unit computers, a central input device for inputting the setpoints is advantageously present, which inputs these setpoints via a data bus the winding units transmitted. However, there is also the possibility of decentralized input at the individual winding units. The completion of a package is usually recorded and counted by the winding station computer. As a result, the winding unit can be stopped easily when the setpoint is reached.
  • the control of the winding unit can be programmed in such a way that the cross-wound bobbin changer still carries out the bobbin exchange, that is to say also already inserts a new tube. After the change, however, the winding unit is not put back into operation.
  • the downtimes can also be determined.
  • a storage channel is provided for each winding unit.
  • the central acquisition of the winding station-related data also allows a comparison of the number of cross-wound bobbins that have already been produced or the downtimes over the entire cross-wound bobbin winder.
  • a monitoring device can therefore easily determine if the time interval between the winding unit with the least downtime and the winding unit with the highest total of downtime becomes so large that it corresponds to the production time of a package. In this case, the monitoring device can increase the setpoint at a predetermined winding position.
  • a cross winder has a closed transport system for caddies which has a distribution section running along the winding units, the length can be shortened by transport locks. This enables groups of adjacent winding units of the package winder to be separated from the supply of cops. This separation occurs when the corresponding winding unit group has been completely decommissioned.
  • the supply of the distribution line via branch lines also allows the supply of the distribution line to be designed with the help of switches so that it is matched to the number of winding units still in operation.
  • a detour route then ensures that cops not supplied to the branch routes can later be distributed to the other branch routes.
  • a ring spinning machine 1 feeds an exchange section 37 to Caddy's 5 cops 3.
  • this exchange path 37 which is common to the Caddy's 5 of the ring spinning machine and Caddy's 6 of the winding machine circuit, the cops 3 and sleeves 4 are transferred to the Caddy's of the other circuit.
  • the caddies 5 of the ring spinning machine circuit with the sleeves 4 again arrive at the ring spinning machine 1.
  • the caddies 6 of the winding machine circuit with the unwound sleeves 4 also arrive at the exchange section 37 and leave it, occupied by the fresh cops 3 of the ring spinning machine 1 , again.
  • Head preparation units 12 and 13 are arranged on the branch lines 8 and 9. There is also no need to go into this here, since it is known to prepare cops in several stages by means of units arranged one behind the other (see for example DE 39 19 526 A1).
  • the arranged after the branch lines 8 and 9 distribution line 16 has an alternately driven in both directions conveyor belt, whereby the caddies 6 with the cops 3 are distributed over the individual winding units of the automatic winder 2 that reserve lines 19 of cross transport lines 17 are constantly filled.
  • This distribution principle is described for example in DE 38 43 554 A1.
  • transverse transport paths 17 lead from the distribution path 16 through unwinding points 18 to a tube return path 11 common to all winding points. At this point it is pointed out that for reasons of clarity only individual caddy's 6 are shown, with two or here three caddy's 6 always being included in the reserve paths 19 Kopsen 3 are on hold.
  • the caddy's 6 leave the respective unwinding position 18 with their sleeves 4 and are fed back to the exchange section 37 via the sleeve return path 11.
  • a so-called head probe 34 is arranged at the downstream end of the sleeve return path 11 in front of a branch 28, which operates on a mechanical or photo-optical basis and differentiates between empty tubes, tubes with very little thread residue and so-called residual tips 22.
  • the remaining bobbins 22 can, however, also be still fully wound bobbins if, for example, the beginning of the thread could not be picked up in the winding station.
  • the head button 34 is connected to two schematically illustrated switches 29 and 30, which control the caddy's depending on the control result of the head button 34. If the head probe has recognized an empty sleeve 4, for example, both switches 29 and 30, which can work, for example, on an electromagnetic basis if the caddy's are partially made of ferromagnetic material, are not activated, so that the caddy 6 with the sleeve 4 on the branch 28 can go directly to the exchange route 37. If a small thread remnant has been recognized, both switches 29 and 30 are activated, as a result of which the corresponding caddy 6 is deflected twice and reaches the secondary transport path 32. A sleeve cleaning device 31, which removes the small thread residue, is arranged on this secondary transport path 32.
  • the cleaned sleeve 4 'with its caddy 6 arrives at the mouth 33 again on the sleeve return path 11. If this cleaned sleeve 4 'then passes through the button 34, it detects an empty sleeve and does not actuate the switches 29 and 30.
  • the switch 29 is activated, whereby the respective caddy 6 transports the side transport line 32 past the side transport line 38 and through a switch 25 to a branch line 39 is redirected.
  • a specific coping cone preparation device 35 is arranged on this branch section 39, which searches for the beginning of the thread specifically on the coping cone. After leaving this head cone preparation device 35, the caddy 6, with the remaining head 22 prepared, reaches the main feed path 7 again via the junction 40.
  • the switch 25 is normally set so that it redirects all incoming caddy's 6 to the branch 39. However, if a sensor arranged downstream on the secondary transport path 38 detects a jam, the switch 25 is switched over, so that the caddies are fed directly to the main feed path 7 via the connecting path 24. This is necessary in order not to jeopardize the proper branching on switches 29 and 30. However, as will be explained further below, this connecting section 24 has a special meaning in connection with a lot or lot end.
  • Modern end winding machines have display and input devices in their end frame, which are connected to the individual winding units via a data bus.
  • the winding units themselves have so-called winding unit computers, in which winding unit-specific data are stored and which also directly control the winding unit.
  • winding unit computers in which winding unit-specific data are stored and which also directly control the winding unit.
  • the central control unit 36 usually present in the end frame of these winding station computers.
  • the number of cross-wound bobbins produced at each winding position is counted automatically from the start.
  • this number is first divided by the number of winding units of the automatic package. This arithmetic operation is to be demonstrated below using a few examples:
  • the starting point is an automatic winder with 40 winding units.
  • the target size is a number of 980 packages.
  • the quotient from division 980: 40 is 24.5. According to a first variant, rounding up and down to the next whole number would result in 20 winding positions with 24 cross-wound bobbins to be produced and 20 winding positions with 25 cross-wound bobbins to be produced.
  • a division of 10 usually corresponds to a section division of an automatic winder.
  • 23 cross-wound bobbins would be produced in the section furthest away from the delivery of the cops, while in the sections lying ahead, 24, 25 and 26 cross-wound bobbins would be produced in a staggered manner.
  • the sections are taken out of operation in a predetermined order.
  • the division according to the second variant would be more advantageous if the production time per cross-wound bobbin is relatively short. This is the case when relatively small packages are wound from relatively coarse yarn. The time interval between the completion of the first packages and the completion the last cross-wound bobbins would therefore not be too large. In contrast, the first variant is preferable if relatively large packages are wound from fine material.
  • the setpoint was reduced by one in three of the winding units that are to produce 24 packages.
  • the setpoint was increased by one for three further winding units. This results in a distribution of 23 winding units which are to produce 25 cross-wound bobbins, 14 winding units which are to produce 24 cross-wound bobbins and three winding units which are to produce 23 cross-wound bobbins.
  • This additional modification serves to correct the setpoint of a winding unit that has had considerable downtime.
  • the setpoint for the number of cross-wound bobbins to be generated by this bobbin is automatically reduced by one.
  • the setpoint for one of the three winding units with a reduced setpoint is increased by one, that is, to 24. If such a measure is not necessary, since, as is normally the case, all winding units work approximately the same, stopping the three winding units mentioned is unproblematic, since the vast majority of winding units can continue to work.
  • a fourth variant which represents a modification of the second variant, it can be provided that there is a reduction in the case of two winding units with the highest target value 26 perform one at a time. This results in the order of 8 x 26, 14 x 25, 8 x 24 and 10 x 23. In any case, it must be ensured that, with a corresponding modification of the series of values, such a correction must also be carried out that the total number of cross-wound bobbins to be produced is reached.
  • winding positions in the program are provided as alternative winding positions if a winding unit is behind by at least the manufacturing time of a package.
  • the division can be made, for example, in such a way that 20 bobbins at 20 winding units, 20 at 19 winding units and at a further 10 winding units 18 are specified as target values.
  • analog modifications can be made in accordance with the variants already explained.
  • the corresponding quantities can be calculated externally or at the central control unit of the automatic winder, provided that it is equipped with the appropriate software.
  • the expected production time of a package can be determined, taking into account average downtimes, which inevitably result, for example, when changing the bobbin or breaking the thread.
  • this value is stored in the monitoring device, which is part of the central control unit 36. In this way, the monitoring device can determine when a residue from a cheese has been reached at a winding unit. The monitoring device then starts the correction in the form of a reduction of the setpoint by one at this winding unit.
  • a predetermined other winding unit is provided with a desired value which is increased by one. The selection of such a winding unit results from the examples described so far.
  • a transport lock 26 can be seen on the distribution section 16. Transport locks of this type are provided at all section boundaries of the automatic winder 2, but this is not shown here. This transport lock 26 is actuated when the rearmost section seen from the cop feed side is completely shut down. As already described, this is done by appropriately staggering the target values for the number of cross-wound bobbins to be produced.
  • Caddy's are forwarded to the detour route 10.
  • These caddy's 6 with excess copes 21 reach the sleeve return belt 11 at the end of the diversion route 10, from where they reach the main feed route 7 again via the secondary transport route 28 and the connecting route 24, as described.
  • the stopper 27 is normally open. It is only closed if, as described, a section releases all the caddies in it.
  • the cheese winder 2 shown in the drawing has two separate branches 8 and 9, whereby the separation into two parts is easily possible.
  • the cops 3 or excess copes 21 of the old batch that were still in circulation could be fed to the two front sections, while the caddies 6 to the copters of the new batch would be set up, would have to be recoded at the same time.
  • Codable caddies are described, for example, in DE application P 40 41 713.1. This new code would be recognized by the sensor, not shown, arranged upstream of the switch 14. The switch 14 would then let these caddies through to the branch line 9.
  • the machine producing the cross-wound bobbin is, for example, an OE or air spinning machine, the cans or flyer bobbin holders are coded instead.
