Definitions

  • the invention relates to a device of the type indicated in the preamble of claim 1 and to a circular knitting machine equipped therewith.
  • a plurality of transport units which are formed respectively from one twisting member and one transport pipe are connected in succession in order to be able to dispose the drawing frames at a comparatively large distance from the loop-forming machine.
  • it is normal in addition to leave a gap between two successive transport units of this type which serves to dissipate the compressed airflows which are required for producing the twists.
  • the entire transport stretch from the drawing frame to the loop-forming machine forms not only a closed system but also one which is rigid and not particularly flexible, said system being connected to an additional collecting line and being able to impede operations at the loop-forming machine.
  • the technical problem of the present invention resides in configuring the initially described device such that it can be handled more easily, can be adapted more easily to the requirements of the individual case and enables even more effective cleaning of the fibre flow.
  • a suction device is disposed in the region of the open gap which forms the air removal opening.
  • the suction device leads to substantially more effective cleaning of the fibre flow or temporary yarn if it is operated in the manner of an open system, for example is disposed below the gap which is formed between two transport units and consequently uses in addition the natural gravity of any dirt particles and the like which are present.
  • the result advantageously is that the lighter particles are removed as before by suctioning out of the fibre flow, whilst the heavier particles, such as e.g.
  • the suction device can abut against an open gap, i.e. a closed system for guiding air is unnecessary, which facilitates access to the various components.
  • FIG. 1 schematically a device for transporting fibre material between a drawing frame and a loop-forming machine
  • FIG. 2 a schematic longitudinal section through a transport unit of the device according to FIG. 1 which is formed from one twisting member and one transport pipe;
  • FIG. 3 a perspective view of the device according to FIG. 1 according to a first embodiment of the invention
  • FIG. 4 details of the device according to FIG. 3 ;
  • FIGS. 5 to 8 various transport units which are configured according to the invention for the device according to FIGS. 3 and 4 ;
  • FIG. 9 a longitudinal section through a device according to FIG. 1 according to a second embodiment of the invention.
  • FIG. 1 shows roughly schematically in a vertical partial section a loop-forming machine in the form of a circular knitting machine 1 with a needle cylinder 2 in which normal knitting needles 3 are mounted displaceably and can be moved at a knitting position, subsequently termed knitting system, with the help of cam parts, not shown, into a receiving position which is suitable for receiving fibre material 4 .
  • the circular knitting machine 1 which can be configured for example as a right/left circular knitting machine, stands on a floor of a workplace or a knitting room indicated by the reference number 5 . An operator can operate the knitting machine 1 from the workplace floor 5 .
  • a plurality of cans 6 are placed on the workplace floor 5 in which slivers 7 comprising fibres are placed.
  • the slivers 7 are supplied to a drawing frame 9 via conveyor belts 8 or the like, which drawing frame is accessible for the operator from a working platform 10 disposed above the workplace floor 5 .
  • a drawing frame 9 is assigned to each of a large number of knitting systems, only one of which is shown in FIG. 1 , said drawing frame having for example three pairs of drawing rollers 11 in the manner known per se.
  • an auxiliary thread 12 which is withdrawn from a supply spool 14 can be supplied to each knitting system if required.
  • the auxiliary thread 12 can be supplied optionally either with the help of a thread guide directly or, as shown in FIG. 1 , via a pair of output rollers 11 a of the drawing frame 9 to the knitting system.
  • a fibre web, not shown, which comes from the drawing frame 9 essentially comprises untwisted staple fibres which are disposed parallel to each other, is supplied, as is evident more precisely in FIG. 2 , to an assigned knitting system with the help of a transport device which is designated in general with the reference number 15 .
  • the transport device 15 contains at least one twisting member 16 and a spinning or transport pipe 17 connected thereto ( FIG. 2 ), three transport units, which have respectively one twisting member 16 a , 16 b , 16 c and a transport pipe 17 a , 17 b , 17 c being connected in succession in the embodiment according to FIG. 1 because of the comparatively large distance of the circular knitting machine 1 from the drawing frame 9 .
  • the first twisting member 16 a in the transport direction of the fibre material 4 is disposed directly behind the pair of output rollers 11 a or the delivery godet 18 of the drawing frame 9 , whilst the last transport pipe 17 c in the transport direction ends close to hook 19 ( FIG. 2 ) of the knitting needles 3 which are extended into the fibre receiving position at the relevant knitting system.
  • a suction element 20 which is connected for example to a central suction device 21 can be disposed.
  • the transport device 15 which is configured as spinning device or each transport unit which comprises twisting member 16 and transport pipe 17 serves according to FIG. 2 for converting the fibre web issued from the drawing frame 9 firstly into a temporary yarn 22 with real twists.
  • the twisting member 16 is formed for this purpose for example from an essentially hollow cylindrical body 23 , the inner cavity of which receives in itself for example the initial portion of the transport pipe 17 and terminates flush with the latter at a front end side 24 .
  • At least one air channel 25 preferably a plurality of air channels 25 , extends from the end side 24 , said air channels all being disposed diagonally relative to a central axis of the transport pipe 17 .
  • the air channels 25 penetrate the wall of the bodies 23 and of the transport pipe 17 and end at an inner wall of the transport pipe 17 .
  • compressed or blown air is supplied by means, not shown, to the ends of the air channels 25 which abut against the outside of the body 23 so that the twisting member 16 draws the fibre material which appears in the delivery godet 18 of the pair of output rollers 11 a into the transport pipe 17 and, at the same time, also conducts it further through the transport pipe 17 in the direction of the relevant knitting system.
  • air turbulence 26 is produced in addition in the transport pipe 17 in such a manner that the fibre material coming from the output rollers 11 a not only is suctioned in but is also spun into the temporary yarn 22 in that a large number of rotations are imparted to it and simultaneously compact the fibre material.
  • the temporary yarn 22 keeps the twists essentially up to the end of the transport pipe 17 , whereupon these twists are then undone again up to the entry of the fibre material 4 into the knitting needles 3 , i.e. are reduced to zero (false twist effect). Therefore a compacted but almost untwisted fibre material 4 enters into the knitting needles 3 .
  • the same effect is obtained if, according to FIG.
  • three transport units comprising twisting members and transport pipes 16 a / 17 a to 16 c / 17 c are connected in succession.
  • These transport units can be disposed, according to FIG. 1 , also at preselected angles relative to each other, as a result of which it is possible to transport the refined fibre material coming from the drawing frame 9 over comparatively long stretches without it being damaged.
  • the compressed airflow required for producing turbulence is discharged externally via air removal openings which are formed by gaps 27 ( FIG. 1 ) between an outlet end 28 of a preceding transport unit (e.g. 16 a , 17 a ) and an inlet end 29 of a subsequent transport unit (e.g. 16 b , 17 b ).
  • Circular knitting machines of the described type are known for example from documents PCT WO 2004/079 068 A2 and DE 10 2006 006 502 A1 which are herewith made the subject of the present disclosure in order to avoid repetitions by reference to them.
  • FIG. 3 shows a drawing frame 9 which has, in contrast to FIG. 1 , two adjacent transport lines for fibre material and therefore respectively two adjacent transport units 16 a , 17 a or 16 b , 17 b or 16 c , 17 c .
  • FIG. 3 shows respectively one thread guide 30 which is disposed at the end of the respectively last transport pipe 17 c , by means of which the supplied fibre material 4 is supplied to the knitting needles 3 ( FIG. 2 ).
  • At least one suction device 31 a , 31 b is disposed respectively in the region of at least one air removal opening or of the gap forming the latter, preferably in the region of all the gaps 27 a , 27 b etc.
  • Said suction device preferably contains a suction pipe which extends closely, with one end, and particularly advantageously from the bottom up to the relevant gap 27 a , 27 b and, with another end, is connected to a suction or low pressure source, not shown.
  • the suction power of the suction source is preferably chosen such that a low pressure of e.g. 20 mbar to 50 mbar below ambient air pressure is set directly at the relevant gap 27 a , 27 b .
  • the suction devices 31 a , 31 b or suction pipes can, as FIGS. 3 and 4 show, stand at least in the region of their suction openings perpendicular to a transport direction v which is prescribed by the transport pipes 17 a to 17 c , as is indicated in FIG. 4 by a central axis 32 b of the suction device 31 b .
  • a central axis 32 b of the suction device 31 b can also be expedient to dispose the suction devices diagonally relative to the transport direction v.
  • the suction device 31 a can also assume positions 31 a 1 and 31 a 2 with axes 32 a 1 , 32 a 2 , shown in broken lines.
  • a diagonal position corresponding to the axis 32 a 1 is for example sensible if an outlet end 28 a of the transport unit 16 a , 17 a which abuts against the relevant gap 27 a is bevelled and provided with a diagonal front or end face 33 a and has an outlet opening which is orientated towards the suction device 31 a and the axis of which extends for example coaxially relative to the axis 32 a 1 .
  • This bevel of the outlet end 28 a is however not achieved in that the transport pipe 17 a is bent over at the relevant end. Rather, a straight pipe is preferably cut diagonally at the end thereof in order to configure the end face 33 a (FIG. 4 ) in order that the axes of successive pipes can be continuously in alignment.
  • the angle at which the end face 33 a is inclined relative to the axis of the transport pipe 17 a can be different, as a comparison with a diagonal front or end face 33 b at the outlet end of the transport pipe 17 b shows in FIG. 4 .
  • FIG. 4 shows in total an embodiment with a diagonally downwardly pointing end face (e.g. 33 a in FIG. 4 ) in combination with a suction device 31 which is attached thereon from the bottom, e.g. in position 31 a 2 .
  • Loose entrained particles are separated in this case, assisted by gravity, particularly easily from the fibre flow or temporary yarn 22 .
  • FIGS. 5 to 8 Further possible embodiments of the configuration of the transport pipes 17 at the outlet ends thereof are evident in FIGS. 5 to 8 . More detailed explanations in this respect appear unnecessary.
  • a further advantageous embodiment can be obtained in that the diagonal end faces 33 a are disposed directed towards the side and the axes of the suction devices 31 horizontally instead of vertically as in FIG. 4 .
  • the diagonal end faces 33 a are disposed directed towards the side and the axes of the suction devices 31 horizontally instead of vertically as in FIG. 4 .
  • undesired sagging of the fibre material in the region of the gap 27 a , 27 b can be extensively avoided.
  • diagonally extending outlet ends confer the advantage that they prescribe a preferred direction for the excess air which is to be removed and direct the latter consequently automatically away from the subsequent inlet opening.
  • a dimension 0 ⁇ x ⁇ 2di is regarded as particularly advantageous, in which di means the internal diameter of the transport pipe 17 a , 17 b which precedes the respective gap 27 a , 27 b .
  • the dimension x is measured respectively from the outermost edge of the preceding transport pipe (e.g. 17 a ) up to the beginning of the inlet opening 29 ( FIG. 1 ) of the subsequent transport pipe (e.g. 17 b ), as FIG. 4 clearly shows.
  • the inlet end of the subsequent transport pipe can thereby be defined by this itself, as indicated in FIG. 1 , or also by the inlet opening of a twisting member (e.g. 16 b ) which is connected to the relevant transport pipe.
  • a twisting member e.g. 16 b
  • the length x indicates therefore the smallest distance between two transport units formed respectively from one twisting member 16 and one transport pipe 17 .
  • the use of the dimensions 0 ⁇ x ⁇ 2di has the advantage that, after breakage of the temporary yarn 22 or running empty of a transport unit 16 , 17 for other reasons, no problems arise with starting to spin again and the forming yarn 22 is automatically threaded into the inlet opening of the respectively subsequent transport unit.
  • the transport pipes 17 a , 17 b and 17 c preferably all have central axes which extend in a straight line.
  • FIG. 1 shows a variant in which at least one transport pipe 17 c is disposed at an angle relative to other transport pipes 17 a , 17 b , however all the pipe axes being in alignment.
  • all three transport pipes 17 a , 17 b and 17 c are in addition disposed coaxially relative to each other.
  • FIG. 4 shows a particularly preferred embodiment for the purposes of the invention which has one substantial special feature.
  • This special feature resides in the fact that the transport pipes 17 a to 17 c , regarded per se, have in fact continuously constant internal diameters, these internal diameters however become gradually smaller from the drawing frame 9 in the direction of the knitting machine 1 .
  • the transport pipe 17 a has the largest internal diameter
  • the transport pipe 17 b a medium one
  • the transport pipe 17 c the smallest one. Consequently, the advantage is achieved that the transport line formed from the transport pipes 17 a , 17 b and 17 c has at the beginning a comparatively large internal diameter and at the end a comparatively small internal diameter.
  • the gap 27 a , 27 b between successive transport units 16 , 17 is expediently dimensioned to be so large that, of the quantity of air which emerges from the preceding transport units which have larger internal diameters, only as much is transferred to the subsequent transport units as they are able to receive because of their smaller internal diameter.
  • the transition from a preceding first transport unit (e.g. 16 a , 17 a ) in the transport direction v to a directly subsequent second transport unit (e.g. 16 b , 17 b ) is chosen to be larger than the transition from this second transport unit (e.g. 16 b , 17 b ) to a further subsequent third transport unit (e.g. 16 c , 17 c ).
  • the temporary yarn 22 forms a comparatively large balloon in the first transport pipe 17 a , which assists good separation of the entrained foreign particles in the subsequent first gap 27 a .
  • the largest part of the impurities is removed already in the region of this gap 27 a .
  • subsequent transport pipes in particular the last transport pipes 17 c respectively in the transport direction v, obtain a correspondingly reduced internal diameter, as a result of which the balloon formation is smaller and a narrower guidance is achieved, which is advantageous for clean insertion of the fibre material into the knitting needles.
  • a further advantageous embodiment provides configuring in fact all the transport pipes 17 a , 17 b and 17 c to be straight and to dispose them with axes which extend parallel to each other, but providing an offset which extends transversely relative to the transport direction v between the axes of successive transport pipes.
  • an offset or spacing A 1 exists for example between the axes of the transport pipes 17 a and 17 b and an offset A 2 between the axes of the transport pipes 17 b and 17 c .
  • offset A resides in the fact that, by means of it, geometric positional differences between the drawing frame outlet and the inlet hole of the thread guide 30 can be compensated for in a simple manner without requiring to bend one of the transport pipes 17 for this purpose.
  • the size of the offset should be chosen in accordance with the individual case and, with normal internal diameters of the transport pipes of e.g. 1.5 mm to 4 mm, should be smaller than or at most just as large as half the internal diameter of the respectively subsequent transport pipe.
  • the direction of the offset A can be such that a subsequent transport pipe is situated offset by the offset A at the side or towards the top or bottom relative to a preceding pipe, the respective position requiring to be chosen in particular with reference also to the air conditions prevailing in the gaps 27 a , 27 b.
  • FIG. 9 shows a further preferred embodiment of the invention which is considered to be best at present, only two transport units, in contrast to FIG. 4 , with respectively one twisting member 35 a , 35 b and a transport pipe 36 a , 36 b which is connected thereto being represented, although here also three or more transport units could be present.
  • the parts 35 a , 36 a here form a preceding transport unit and the parts 35 b , 36 b a subsequent one.
  • an open gap 39 which is intended to form an air removal opening is provided.
  • a suction device 40 is disposed.
  • the latter has a suction chamber 42 which is connected to a suction pipe 41 , said suction chamber being sealed by a first end wall 42 a and a second end wall 42 b which is expediently parallel and opposite to said first end wall, said end walls being disposed essentially perpendicular to the transport direction of the fibre material and at a spacing from each other.
  • the transport pipe 36 a of the preceding transport unit protrudes through a passage of the first end wall 42 a and extends with its free end portion which forms the outlet end 37 up to the gap 39 and the second end wall 42 b disposed there.
  • This end wall 42 b is provided with an outlet opening 43 which is situated opposite the inlet end 38 a of the subsequent transport unit and the inner cross-section of which outlet opening is larger than the outer cross-section of the transport pipe 36 a of the preceding transport unit at this position.
  • the free end portion of the transport pipe 36 a can protrude through the outlet opening 43 in particular in such a manner that its outermost edge, which establishes the length x of the gap 39 with the beginning of the inlet opening 38 analogously to FIG. 4 , projects slightly outwards beyond the inlet opening 37 and protrudes into the gap 39 , as FIG. 9 shows clearly.
  • the cleaning effect is particularly good if the transport pipe 36 a is disposed in the first end wall 42 b sealed for example with the help of an O-ring 44 and therefore the suction effect of the suction pipe 41 becomes effective almost exclusively in the region between the edge of the outlet opening 43 and the transport pipe 36 a.
  • the second end wall 42 b is configured expediently as a cover which is connected in a sealed and detachable manner to the suction chamber 42 .
  • a further O-ring 45 can serve expediently for sealing.
  • the suction chamber 42 can be configured, apart from the suction pipe 41 and the region between the end wall 42 b and the transport pipe 36 a which opens into the gap 39 , as a completely closed housing which is situated opposite the inlet end 38 of the subsequent transport unit 35 b , 36 b at a spacing.
  • Corresponding suction chambers 42 can be provided at the transitions between further, not shown transport units.
  • transport units evident in FIG. 9 can be constructed analogously to those according to FIGS. 1 to 8 .
  • the invention is not restricted to the described embodiments which can be modified in many ways.
  • the described angles evident in the drawing, at which the end faces are bevelled at the outlet ends of the transport units should only be understood as examples which can be deviated from according to expediency.
  • the same is true for the angles between successive transport units (e.g. 16 b , 17 b and 16 c , 17 c in FIG. 1 ).
  • the transport pipes 17 and 36 can have different circular inner contours from those tacitly assumed here. If the contours deviate from the circular shape, the average internal diameter of a transport pipe is expediently used as dimension di.
  • twisting members other than those described, in particular also mechanical ones, can be applied.
  • transport pipes the inner jackets of which are provided with at least one helical groove, can be used in order consequently to improve the rotation of the temporary yarn in the transport pipes, the pitch of the grooves requiring to be chosen as a function of which twists are prescribed by the twisting members.
  • the described transport devices can also be formed on loop-forming machines other than the described circular knitting machines.
