Definitions

  • the invention relates to a method for performing a Batch change on an automatic winder according to Preamble of claim 1.
  • Modern automatic winding machines usually have a large number similar winding sections arranged in sections and a Transport system for supplying and disposing of these winding units Spinning bobbins or empty tubes.
  • a transport system which is known to be several different transport routes, including those to the Has winding stations leading cross transport routes run Transport plate with vertically arranged mandrels around, on which either spinning bobbins or empty tubes are transported.
  • Processing stations for the spinning heads or for the empty tubes such as cop preparation stations, Case guard, case cleaner, etc. arranged.
  • the transport system of an automatic winder can either directly via a so-called converter Transport system of an upstream spinning bobbin producing textile machine, one speaks then from a textile machinery network, or the transport system of the automatic winder is via a special interface with spinning heads of a separately arranged ring spinning machine supplied or disposed of empty tubes.
  • Such an interface consists, for example, of an im Area of a so-called takeover line arranged Kopsaufsteck noticed of a flat circular conveyor is connected upstream and a sleeve pulling device.
  • head attachments e.g. through the (DE 33 48 033 C2), as well as flat round conveyors e.g. through the (DE 41 12 434 A1) or sleeve pulling device by (DE 44 46 161 A1) known in principle.
  • Spooled empty tubes are removed by the tube pulling device removed from the transport system and in a transport container stored.
  • this object is achieved by a method as described in claim 1.
  • the method according to the invention has the advantage over the previously known methods that the clearing of the old yarn section, the intermediate storage of the empty transport plates and the filling of the new yarn section take place in a completely controlled manner from the start.
  • the transverse transport routes leading to the winding stations are used as a buffer which can be loaded in a defined manner for empty transport plates, without any additional blocking or control means being necessary in the entrance area of these transverse transport routes.
  • Three of a total of five transport plates per winding unit are inserted one after the other into the transverse transport lines. At the end of the clearing process, the two remaining transport plates are temporarily stored on the tube return line or the distribution line and are there immediately ready for filling with spinning heads of a new batch of yarn.
  • Transport plate When filling the cheese winder with spinning heads a new one Yarn section is through the targeted discharge of the Empty, empty, temporarily stored cross transport routes Transport plate also ensures that all winding units of the automatic winder relatively evenly with spinning bobbins new yarn section and thus all winding units can go into production at the same time.
  • the batch changing method according to the invention is characterized by great speed.
  • the method according to the invention leads overall to an improvement in the efficiency of an automatic winder.
  • the method step set out in claim 3 ensures in particular in connection with those in claims 11 and 12 procedural steps outlined, on the one hand, that the Ejecting the spinning reel-loaded transport plates from the Cross transport sections of a winding unit section are carried out quickly, on the other hand, it is avoided in this way that it on the Sleeve return path to a jam of the discharged Transport plate and thus to jam this Transport plate in the mouth area of the cross transport lines can come because such jams can often only be remedied manually are.
  • the branch lines arranged first with respect to the conveying direction of the cop feed line discharge the spinning head-carrying transport plates to the storage line, while the rear one of the branch lines delivers the transport plates to the head supply line. Since the transport plates diverted to the cop feed line are first retrieved, the transport stream of spinning head-carrying transport plates to be unloaded in a removal line can be somewhat evened out in this way.
  • One preferably arranged in the area of a pull-off section Cop removal device ensures that the spinning cops of the old yarn section continuously and the yarn layers gently from the transport plates are taken (claim 6).
  • a transport system 21 of an automatic winding machine (not shown) is indicated schematically in FIG.
  • spinning copes which were produced on a separately standing ring spinning machine, are fed to the transport system 21 via an interface, a so-called cop attachment 22.
  • Empty tubes are disposed of via the tube pulling device 20 and then conveyed back to the ring spinning machine.
  • Figure 1 shows a situation as it happens during represents the normal winding operation.
  • transport systems 21 have a large number different transport routes over which the winding units the automatic winder with spinning bobbins be disposed of by empty tubes.
  • Figure 1 is in the area of a takeover line 1
  • Flat circular conveyor 20 with a cop attachment 22 and an empty sleeve pulling device 23 is indicated.
  • joins in with such transport systems Takeover line 1 a Kopszu slaughterhouse 2, from the Branch or preparatory sections 3a, 3b, 3c.
  • the Detachment or preparation routes 3a, 3b, 3c are over Transport routes 4 connected to a storage route 5, which in turn has numerous cross transport routes 6 a sleeve return path 8 is connected.
  • To the A return section 9 closes a sleeve return section 8 which flows into takeover route 1.
  • the sleeve return path 8 is also a Connection path 7 connected to the cop feed path 2.
  • actable Stop devices 25a and 25b installed in the area of the link 7 and in the area of Sleeve return path 8 are defined.
  • a so-called transverse passage 10 extends, which extends between the distributor section 9 and the cop feed section 2, to which a sleeve cleaning section 11 with a sleeve cleaner 16 arranged there is connected.
  • the sleeve cleaner section 11 finally merges into a manual preparation section 12 which functions as a peeling section.
  • the cop pulling device 26 is arranged in the area of the pull-off section 12.
  • Transport plates During normal winding operation run within the Transport systems 21 numerous transport plates around either are equipped with spinning bobbins or empty tubes.
  • the Transport plates are usually only in the area Takeover path 1 between the empty tube pulling device 23 and the Kopsaufsteck issued 22 briefly empty.
  • FIG. 1 shows spinning head-carrying transport plates with 19, empty transport plates with 18 and empty ones Transport plate marked with 17.
  • the transport plate run within the transport system 21 in the transport direction T around.
  • FIG. 2 shows the situation at the beginning of the batch change process according to the invention.
  • the winding units (not shown) of the automatic winder have stopped their winding operation.
  • the bobbin plug-in device 22 arranged in the area of the take-over line 1 is switched to “locks”, that is, incoming empty transport plates 17 are no longer fitted with spinning bobbins, but instead run directly to the bobbin feed line 2.
  • the branching and preparation lines 3a, 3b and 3c are controlled in such a way that the spinning head-carrying transport plates 19 standing on these lines are discharged.
  • the transport plates 19 standing on the branching and preparation lines 3a and 3b are sent via the removal lines 4 to the storage path 5, while the transport plates 19 of the branching and preparation line 3c are discharged to the cop feed line 2.
  • each of all transverse transport routes 6 becomes one spinning head carrying transport plate 19 on the Sleeve return path 8 out and the Link 7 temporarily taken out of service.
  • the spinning head-equipped transport plate 19 are from Sleeve monitor 15 is diverted to the withdrawal section 12 and there either mechanically by means of a cop pulling device 26 or unloaded manually by the operating personnel.
  • Transport plate 18 carrying empty tubes sluices the Sleeve watchers to takeover line 1, where they through a Empty sleeve puller 23 are freed from the sleeve.
  • the winding unit sections A and B of spinning head-carrying transport plates 19 are exempted Stop device 25 in the area of the sleeve return path 8 activated.
  • the spinning head carrying transport plates 19 are as long in front of the stop device 25 until all Bobbin sections are cleared. Then the Stop device 25 deactivated and the transport plate on the Pulling section 12 freed from the spinning cops.
  • FIG. 6 shows a situation as it appears when all spinning bobbins and empty tubes of the old batch of yarn from the Transport system 21 of the cheese winder are removed and in the transverse transport routes 6 and on the Sleeve return section 8 or on the distribution section 9 only still empty transport plate 17 for receiving the spinning heads ready new thread section. As indicated are about 60% of the empty transport plates in the cross transport routes 6 and about 40% on the sleeve return path 8 cached.
  • the empty transport plates 17 on the tube return path 8 on the cop attaching device 22 are first equipped with spinning bobbins of the new yarn section.
  • These transport plates 19 are conveyed via the cop feed line 2 to the branching and preparation lines 3a and 3b and are processed there, as usual, by the preparation stations 14a and 14b.
  • the spinning bobbins prepared on the preparation stations 14a and 14b reach the storage path 5 via the preparation lines 3a and 3b or the removal lines 4, the conveyor belt of which initially runs in the direction of the front preparation station 14a.
  • an empty transport plate 17 is removed from all the transverse transport routes 6 of the transport system 21, as indicated in FIG. 7, and space is thus created in the transverse transport routes 6 for accommodating one transport plate 19 equipped with a spinning cop.
  • the storage path 5 which is switched at least temporarily to return R, these free spaces on all transverse transport paths 6 are filled up with a transport plate which carries a spinning cop of the new yarn section.
