Definitions

  • the invention relates to a roving machine with a device and a method for the automatic replacement of full roving bobbins for empty roving sleeves in the form of hanging wagon trains with hanging brackets, in which the roving bobbins and roving sleeves are suspended by lifting movements of a carrying device for the roving bobbins and roving sleeves of the roving machine.
  • the hanging carriage trains are arranged essentially at the same height as the wing bench behind the wing bench.
  • the bobbin bank must be moved from its working position under the wing bench backwards under the transport device. This makes a very extensive structural redesign of the roving machine necessary.
  • the displaceability of the heavy spool bank, which is connected to the machine frame by a drive device, by the intended distance is very complex in terms of design and construction.
  • the object of the invention was to improve a device for the automatic replacement of full roving bobbins for empty roving tubes on a roving machine of the type mentioned at the outset so that the disadvantages listed are avoided.
  • the guide means are arranged in this area according to the invention and form a guideway for the hanging trolley train extending through this area.
  • the guide means according to claim 2 are arranged on the underside of the wing seat or according to claim 3 on the underside of the wing heads located directly below the wing seat.
  • Wings of roving machines are already known (DE 27 51 264), which have resilient retaining clips on the underside of their head, which can engage with grooves at the upper end of the roving sleeves and pull the full bobbins off the bobbin spindles when the bobbin bank is detected the sleeves are lowered. The full bobbins recorded in this way must then be removed by hand.
  • This device does not provide for the insertion of empty sleeves. It also requires special sleeves with a groove at the top.
  • the guiding means cannot be made continuous and arranged in a stationary manner. They are therefore divided according to the invention into the guide means arranged in a stationary manner on the underside of the wing bench, which can only extend over the area not covered by the wings during circulation, and in the guide means arranged on the underside of the head of the wing according to claim 3. This inevitably leaves larger or smaller gaps in the guideway.
  • the hanging trolley trains can be guided solely by means of fixedly arranged guide means on the wing bench or solely by means of guiding means arranged under the heads of the wings, if the individual trolleys of the hanging trolley train are cantilevered in particular in the direction of movement so that, particularly when entering the row of wings, the gaps in the Can bridge the guideway.
  • the carriages must have a minimum length that limits their ability to negotiate curves or requires large radii of their guideway outside the prespinning machine, which are undesirable or not possible in a spinning mill.
  • the guide means used according to the invention can in principle be designed in the manner known for hanging wagon trains, that is to say as rails, in, on or on which support members such as rollers or pairs of rollers or rail lines of the hanging wagon trains roll or slide or in kinematic reversal as support members such as rollers or pairs of rollers or guide rails, in, on or on which the guide troughs of the hanging trolley trains are guided in a rolling or sliding manner.
  • the guide means according to claim 4 as separate, but in their entirety forming a guideway rail sections, which offer the advantage of guiding a trolley pull in a direction-oriented manner in the intended direction of movement. This applies in particular to the guide means which are arranged in a stationary manner under the wing bench.
  • Guide means designed as rails on the surrounding wings require that all wings are aligned exactly when a hanging trolley train is pulled in so that the rail sections in the wings are aligned with one another or with rail sections attached to the wing bench, so that the tip of a hanging trolley train entering a row of wings can be easily moved one section of rail can pass to the next.
  • external guide elements in particular rails, on the side on which the hanging trolley train enters them, can be funnel-shaped or internal guide elements such as, in particular, the beginning of the first carriage of a hanging wagon train with centering guide curves.
  • the embodiment of claim 5 appears advantageous in many cases, since it saves the height of the wagon by sharing the wagon body , which is particularly advantageous in the present case.
  • wing bench guide means can of course also be designed as a support means according to claim 5.
  • two or more suspension elements of this type can be arranged at a distance from one another.
  • the thickening of the pin according to claim 6 can be designed according to claim 7 as a sliding block.
  • a dome-shaped sliding block allows the hanging wagon train to swing. If this is to be avoided, a sliding block having a mating surface and positively encompassed by the guide trough can be used.
  • the Sliding friction between the large number of sliding blocks, which carry and carry a hanging trolley train, which is particularly heavy when attached to full roving bobbins, and the guide trough of the hanging trolley train can be reduced by choosing suitable pairings of the material of the sliding surfaces. A significantly more effective reduction in friction can be achieved by changing over to rolling friction, in particular in the space-saving embodiment mentioned in claim 8.
  • a flat steel band is placed lying in the hanging wagon train, which stiffens it transversely to its direction of movement.
  • a latch which can be folded down when a hanging wagon train moves into the pre-spinning machine and which connects the two cars with one another in a directionally stable manner.
  • Common sleeves for roving machines have a tube constriction at the upper end, which serves in the roving machine for the radial guidance of the sleeve and its lower shoulder in the creel of the ring spinning machine as a catch for the hanging holder.
  • known sleeves with two superimposed pipe constrictions can be used, the lower one serving as a guide for the sleeve on the bobbin spindle and the upper one serving as a catch for the hanging holder .
  • the hanging trolley train can have a double number of hanging brackets corresponding to the number of coils or sleeves standing in a row of wings, which are then arranged in the coil bank at half the pitch of the coils.
  • This embodiment requires the method described in claim 16 for replacing the coils or sleeves. With a small pitch between the coils in the coil bank, it may be more advantageous to equip the hanging trolley train only with the number of coils or sleeves standing in a row of wings. In this case, the method described in claim 17 for replacing the coils or sleeves results.
  • the roving machine 1 of common design has a drafting system 2, which delivers stretched roving lines 3 to the inlet pipes 4 of the wings 6 mounted in a wing bench 5.
  • the rovings formed by the rotation of the wings 6 each pass through one arm of the wings and are passed via pressing fingers 7 onto the bobbin tubes 8, on which they are caused by the speed difference between the wing and bobbin tubes and the up and down movement of a bobbin bank 9 carrying the bobbin tubes Windings of the coils 10 are wound.
  • the organs for the rotary drive of the wings 6 and the bobbin spindles carrying the bobbin sleeves 8 and for moving the bobbin 9 up and down are known and are therefore neither shown here nor described in detail.
  • the bobbin bank 9 is lowered to its lowest position and the wings 6 are transverse to the longitudinal axis of the roving machine.
  • a hanging wagon train 11 is inserted into the first row of wings by means of a friction roller pair 12 known per se, which resiliently presses against opposite side surfaces of the wagons of a hanging wagon train, of which at least one roller can be driven by a motor 13.
  • the front of the first carriage 14 and the front wing arms of the wings 6 of the front row of wings of the roving machine 1 with two rows of wings are partially broken away to make the guidance of the hanging carriage train 11 recognizable.
  • This guidance is carried out by means of guide means which are attached to the underside of the wing heads 15 and are more clearly recognizable from FIG. 4 and which are designed here as spherical caps 17 carried by retaining pins 16 and by means of a dovetail-like guide groove 18 in the hanging carriage 14.
  • the individual, at least laterally movable with one another via pivot axes 19 connected wagons 14, 20 of the suspension wagon train 11 have a distance of half the distance between the wings 6 of this row of wings
  • Hanging holder 21 of the known type which alternately detect and release these coil sleeves when pressed into tubular coil sleeves 8. Every second hanging holder 21 is equipped with an empty sleeve 8.
  • both hanging trolley trains are fully retracted under both rows of wings of the pre-spinning machine, there is an empty hanging holder 21 above each full spool 10: FIG. 2.
  • these hanging holders 21 enter the spool sleeves 8 of the coils 10 and capture them - Fig. 3 - so that they remain attached to the hanging trolley during the subsequent lowering of the coil bank.
  • the trolley trains move by the mutual distance between their hangers 21, so that an empty sleeve 8 comes to rest on each spool spindle.
  • the bobbin bank 9 is now raised again to the position in FIG. 3, these empty sleeves are released from their hanging holders and remain on the bobbin spindles when the bobbin bank is moved downward.
  • the changeover process is thus ended and the hanging trolley trains can be moved out of the pre-spinning machine with the attached full spools 10 by means of the pair of friction rollers 12.
  • the hanging trolley trains can be driven into the gate of a ring spinning machine and presented there. However, since the distances between the spindles on the roving machine and the supply spools in the creel of a ring spinning machine do not match, the roving spools are usually reassigned or otherwise handled in suspension trolley trains of a corresponding other division. After the full bobbins have been removed, the hanging wagon hoists are again filled with empty tubes and are ready for the next changing process on this or another pre-spinning machine.
  • the guide means are arranged under the wing heads 15. They are designed as rotationally symmetrical parts that can carry and guide a suspension trolley in all the turning positions of a wing.
  • the calottes 17 can be replaced by rollers. 5 shows an embodiment in which two frustoconical rollers 22, 23 are mounted on laterally offset bearing sections 24, 25 of the holding pin 16. It is thereby achieved that the two rollers 22, 23 rest on opposite sides against guide surfaces of the guide troughs 18 of the carriages 14, 20 of the hanging carriage train 11 and roll on them.
  • the first carriage 14 of a hanging wagon train 11 moving into a row of wings has to bridge larger distances between these guide means and drive safely onto the next respective pin.
  • a thin, flexible steel band 26 as is known, for example, from tape measures, can be inserted into the carriages 14, 20 of the hanging carriage train at the entry point of the hanging carriage train 11 into the row of wings.
  • the steel strip 26 is rolled up in a spiral 27 when it is not required.
  • the hanging trolley pulls in it is inserted into the hanging trolley pull in synchronism with the movement of the hanging pull pull by means of a drivable conveyor roller pair 28 through a guide channel 29, its beginning being able to be anchored in a recess 31 of the first push pull 14 of the hanging pull pull by means of a bolt 30.
  • the steel band 26 cannot be wider than the inside width of the guide trough 18 on the hanging trolley train, but the inside width of this guide trough is greater at the level of the support of the steel band 26, as shown in FIG. 4, there is a groove 32 in the width of the steel band provided, in which the steel strip is embedded.
  • securing means for example in the form of ball pressure elements 33 on the underside of the calottes 17 or - as not shown - magnets in the groove 32 prevent the steel strip 26 from inadvertently emerging from this groove.
  • FIGS. 7 and 8 Another possibility, shown in FIGS. 7 and 8, is to expediently pivotably mount a bolt 34 in a preceding carriage 14 of the hanging carriage train 11, which bolt can be pivoted into a groove 35 of the following carriage which is matched to it.
  • the bolt 34 has a laterally projecting pin 36 which projects into the region of guide rails 37 and 38 at the entry point of the suspension carriage train 11 into the pre-spinning machine 1.
  • the bolt 34 is provided with holding means in the form of a ball pressure lock 39 or - indicated by dash-dotted lines - a pair of magnets 40 which hold it releasably in the drawn locking position.
  • FIGS. 9 to 15 show embodiments in which the guide means are designed as rail sections 41, 42, in or on which support means of the carriages 14, 20 are guided, for example, in the form of rollers.
  • the rail sections 41, 42 are arranged both under the heads 15 of the wings 6 and on the underside of the wing bench 5.
  • the rail sections extend up to close to the limit of the movement space 43 of the wings 6 indicated by dashed lines.
  • the fixed rail sections 42 arranged under the wing bench 5 and the rail sections 41 arranged under the wing heads 15 form the wings 6 in the position of The wings transversely to the longitudinal axis of the roving machine 1 interact with a dashed line continuous guideway with only small gaps 44, in which a suspension trolley is guided in an absolutely stable direction.
  • guide means in the form of rail sections 41 are arranged only under the wing heads 15 of the wings 6. As can be seen, these rail sections 41 can also complement one another in the transverse position of the wings 6, which is assumed in the illustration, to form an almost complete guideway.
  • the carriages 14, 20 of the hanging carriage train 11 are equipped with suspension means in the form of rollers 45 with a horizontal axis or, as shown, with inclined axes which point to the Roll off the guide surfaces 46 of the rail sections 41, 42.
  • these rail sections 41, 42 can be expanded in a funnel-like manner on its inlet side 47.
  • the first carriage 14 of the hanging carriage train has, as can be seen from FIGS. 16 and 17, on a support rod 48 on a deflecting rail 49, which presses the pressing fingers 7 aside behind a level 50, which lies outside of level 51, within which the full bobbins hanging on the hanging wagon train move, when the hanging wagon train moves in the direction of the arrow.
  • the deflecting rail 49 acts in the illustrated press finger arrangement only in the illustrated direction of movement of the suspension carriage train 11. Provided that the wings 6 in the other row of wings of the roving machine are offset by 180 ° as usual and accordingly, the press fingers point in the other direction, the suspension carriage train of this row of wings can move into the row of wings from the other side.
  • FIG. 18 and FIG. 19 shows and describes an embodiment in which, for this purpose, a separately movable device is provided which is separate from the coil bank.
  • This device consists of a board 52 which is guided by slides 53 on vertical columns 54. It lies in the plane of the feet of the coils 10 or sleeves 8 and grips under these feet or can be provided with spring-loaded pliers (not shown here) or actuatable by means of a working element for gripping these feet.
  • the board 51 lies on the spool bank 9 and moves up and down with it. If after the completion of the bobbins 10, the bobbin bank 9 has been lowered into the position shown in FIG. 18, the board detects these full bobbins and is moved by means of a tension member 55 which is guided over a roller 56 moved by a controllable auxiliary drive, not shown, moved upwards until the full bobbins are suspended in the hanging holder 21. Then the board 52 is lowered again so far that it does not hinder the moving or extending and retracting of the hanging holder trains.
  • the empty sleeves 8 can then be removed from the hanging brackets 21 of the hanging trolley train 20 and placed on the spool holders of the spool bank 9.
