Abstract

So that full bobbins 10 and empty tubes 8 can be transferred to and from suspended carriage trains 11 on a roving frame 1 in a way which is as simple as possible and which necessitates only slight constructional modifications on the roving frame, it is proposed to move the suspended carriage train into the changing position on a guide track running through the fliers 6. For this purpose, there are arranged under the heads 15 of the fliers 6 and/or under the flier rail 5 of the roving frame 1 guide members 17, 22/23, 41, 42 which, especially in the transverse position of the fliers 6 relative to the longitudinal axis of the roving frame, form a guide track carrying a suspended carriage train 11. <IMAGE>

Description

The invention relates to a roving machine with a device for 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.

In a known roving machine of this type (DE 39 36 518 A1), the hanging carriage trains are arranged essentially at the same height as the wing bench behind the wing bench. To replace the full roving bobbins with empty roving tubes, 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. So that the spool bank can be shifted over the intended distance, no support for the wing bench can be provided in the shifting area - the wing bench, which protrudes anyway, protrudes at least twice as much as usual and is therefore subject to much more disadvantageous vibrations and vibrations.

A likewise known solution (EP 0 031 844), in which the wings of the roving machine are folded away laterally, is no less complex in terms of design, in order to allow access to the full bobbins from a device that descends from above with a band equipped with hanging brackets.

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.

It solves this task with the features mentioned in the main claim. In order to be able to guide the hanging trolley train in the space outlined by the wing heads and the wing arms of the wings which are transverse to the longitudinal direction and by the spool bank, 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. To make this possible, 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.

In this way we achieve that with minimal intervention in the construction of the roving machine - essentially only the height of the wings has to be increased by about a hand's width - the possibility is created by lifting and lowering a device carrying the coils and sleeves in this area without manual intervention by an operator to guide empty cores to all spinning positions of the roving machine, to hang all full spools of the roving machine from the spool bank onto the hanging trolley train at the same time and to bring the empty cores from the hanging trolley train to the spool holders in the spool bank and to move the spool carriage train so that the Rewinding machine can restart after a very short time.

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.

It is also already known (EP 0 023 193) to provide on the underside of the wing bench of a roving machine in the wings, grippers which grip the full bobbins on flanges at the upper end of the bobbin sleeves and which pivot the full bobbins out of the wings and for removal perform. In this embodiment too, however, the coils must then be removed by hand and handled further.

Since the guideway in the present invention runs through the area of rotation of the wings, 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. To do this, however, 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.

However, a practically complete and therefore particularly safe guidance and mounting of a hanging wagon train even with short carriages is achieved when guiding means are used both stationary on the wing bench and with the wings all around.

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.

It is preferably provided that 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.

The wings are driven positively. If the entirety of the wings is brought to a standstill, the individual wings are therefore at an angle, so that their rail sections are aligned. If it should prove necessary to compensate for tolerances, depending on the embodiment implemented, 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.

On the safety of the changing process, ie on the reliable threading of the bobbin sleeves into the hanging holder or on the bobbin spindles, deviations in the angular position of wings from the intended transverse position have no adverse effect if the suspension means sitting on the carriage of the hanging wagon train advantageously coaxially with hanging brackets are arranged. Because when changing the hanging trolley is so longitudinally adjusted that the hanging hanger in the plane of the wing then this is also the case for the suspension elements. In this plane, a rail arranged on a wing and thus also a suspension element standing in it remains in the axis of the wing and coils even if the angular position of the wing deviates from the desired position.

Since, due to the position of the guideway for the hanging wagon train, which is typical of the invention, a continuous rail track is not possible, but the wagons of the hanging wagon train extend along the guideway, 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.

According to claim 2 arranged on the underside of the wing bench guide means can of course also be designed as a support means according to claim 5. In order to improve the guidance of the suspension carriage train in this embodiment, two or more such suspension elements can be arranged at a distance from one another.

The formation, in particular, of the guide means arranged on the wings according to the proposal of claim 6 as a rotationally symmetrical pin located in the axis of rotation of their wing has the advantage that these guide means are suitable for guiding a suspension wagon pull equally in all rotational positions of a wing. It is obvious that the wings must be approximately transverse to the longitudinal direction of the machines, since only in this wing position is there a clear space that allows the movement of a hanging wagon train with full roving bobbins within the wings. The design of the guide means according to claim 6, however, allows much more tolerances with respect to the transverse position than rails on the wings.

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.

If only cone-shaped, non-directionally stable guide means are provided, suitable measures must be taken to ensure that, in particular, the first carriage of an incoming hanging wagon train slides safely onto the next cone and that the following carriages do not sag. If the coupling between the carriages can be moved on all sides because, for example, the hanging wagon train should not only travel through horizontal curves, but also be height-adjustable, this is only possible if the carriages are so long that they are always guided by at least two pins.

Long carriages increase the radius of the curve, which is undesirable in spinning mills and sometimes not possible. If the carriages are therefore pivotally connected only in a horizontal plane by means of vertical pivot axes, at least the two first carriages of a hanging carriage train can be coupled rigidly to a certain extent to form a carriage of greater length. Two advantageous embodiments of a coupling element that can be used for this purpose are the subject of claims 11 and 12.

In a first embodiment according to claim 11, it is provided that at the entry point of a hanging wagon train into the pre-spinning machine, a flat steel band is placed lying in the hanging wagon train, which stiffens it transversely to its direction of movement. In another embodiment according to claim 12, at least between the first two carriages of a hanging wagon train there is 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. In order to be able to use the hanging holder of the present invention also with sleeves seated on the bobbin spindles of the roving machine, 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 .

As is known per se, 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.

In the working phase shown in FIGS. 1 and 2, the roving bobbins are finished, the bobbin bank 9 is lowered to its lowest position and the wings 6 are transverse to the longitudinal axis of the roving machine.

From the right, a hanging wagon train 11 is being 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, at least one of which 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, when pressed into tubular coil sleeves 8, detects and releases these coil sleeves alternately. Every second hanging holder 21 is equipped with an empty sleeve 8.

If 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. When the spool bank 9 is then lifted into the position shown in FIG. 3, 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. Then 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. If 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.

In the embodiment of FIGS. 1 to 4, 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.

In order to keep the frictional resistance of the sliding friction between the plurality of spherical caps 17 and the guide grooves 18 low, materials with a low coefficient of friction are provided for the sliding surfaces. Suitable materials are offered by specialized companies. In order to allow rolling instead of sliding friction, 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.

1 to 5, 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.

In order to ensure this, according to FIG. 6, 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. When 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.

Since 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. By 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.

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.

When the suspension trolley train 11 enters the roving machine 1 in the direction of arrow A, the pin 36 of the bolt 34 hanging down in dash-dotted position slides over the guide rail 37 and thereby lifts the bolt into the drawn locking position, in which the two carriages 14 are drawn , 20 couples rigidly together and is held by the holding means 39 or 40. When the suspension carriage train 11 extends from the roving machine 1 in the direction of arrow B, the pin 36 runs against the guide rail 38 and thereby releases the bolt 34 from its locking position.

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. In the embodiment of FIGS. 9 and 10, 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. As can be seen particularly from FIG. 10, 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 hanging trolley are absolutely stable.

In the embodiment of FIGS. 11 and 12, 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 gapless guideway.

For guiding in these rail sections 41, 42, as shown in FIGS. 13 and 14, 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.

In order to compensate for slight deviations of the wings 6 from the transverse position by, for example, the angle a, at which the rail sections 41 arranged on the wings are not exactly aligned, when the suspension means 45 transition to these rail sections, these rail sections 41, 42, as shown in FIG. 15, can be expanded in a funnel-like manner on its inlet side 47.

In order to guide the pressing fingers 7, which can remain in an undefined position after the pre-spinning machine 1 has come to a standstill, out of the movement path of a hanging carriage train 11 equipped with full bobbins 10, 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 50, 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 hanging carriage train of this wing row can move into the wing row from the other side.

As an alternative to the embodiment described above, in which the vertical movement of the bobbins 10 or sleeves 8 between the bobbin receptacles in the bobbin bank 9 and the hanging brackets 21 in the hanging carriage train 20 is carried out by moving the bobbin bank up and down, 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.

During normal operation of the pre-spinning machine, 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.

By correspondingly moving the board 52 up and down, 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.
