Definitions

  • the present invention relates to a device for conveying isolated tableware organs such as strands and lamellae in a warp thread drawing machine between a place where the tableware organs are separated from a stack and a place where warp threads are drawn into the tableware organs.
  • Previously known devices of this type such as those used in the USTER DELTA warp threading machine (USTER - registered trademark of Zellweger Uster AG), comprise a large number of different elements, each of which only ever performs a limited part function within the stated process.
  • this means for example, that after they have been separated, they are transported from the first organs to the pull-in position, grasped there by second organs and rotated for alignment for the warp thread pull-in and then transported onwards by third organs, the various organs sometimes only being non-positive are connected to the slats.
  • the interfaces between the different organs within the device in particular represent potential sources of error. This applies in particular if there is a non-positive connection between the organs and the lamellae.
  • a heald magazine in which a device for separating tableware organs (strands, lamella) from a stack and for positioning these tableware organs in front of the stack is provided in such a way that a warp thread can be drawn in.
  • Two different mechanical elements are provided for separating and advancing the tableware organs, transferring the tableware organs to these elements and between these elements.
  • the invention is now intended to provide a device of the type mentioned at the beginning in which the potential sources of error are minimized and the costs are kept as low as possible.
  • This object is achieved according to the invention by holding means for receiving the separated tableware organs and for their form-fitting transport to a feed and transfer station, by positioning means arranged in the area of the feed station, and by transfer means arranged in the area of the transfer station for transferring the tableware organ having a drawn-in warp thread to the supporting elements.
  • the device according to the invention therefore only requires a single type of handling means for handling the strands or lamellae, from their separation to their transfer to their supporting members. And that means that by eliminating a variety of potential sources of errors and causes of faults the device is much less susceptible to failure during operation.
  • the device only needs two interfaces for integration into the pulling-in process, one to the separating station and one at the transfer station to the supporting members. This also significantly reduces the susceptibility to faults and also opens up the possibility of a modular construction of the drawing-in machine.
  • the drawing-in machine consists of a base frame 1 and of various assemblies arranged in it, which each form a functional module.
  • a warp beam carriage 2 with a warp beam 3 arranged on it can be seen.
  • the warp beam carriage 3 also contains a lifting device 4 for holding a frame 5 on which the warp threads KF are stretched. This clamping takes place before the actual pulling-in and at a location separate from the drawing-in machine, the frame 5 being positioned at the lower end of the lifting device 4 in the immediate vicinity of the warp beam 3.
  • the warp beam carriage 2 with the warp beam 3 and lifting device 4 is moved to the so-called upgrade side of the pulling-in machine and the frame 5 is lifted up by the lifting device 4 and then assumes the position shown.
  • the frame 5 and the warp beam 3 are moved in the longitudinal direction of the base frame 1. With this shifting, the warp threads KF are guided past a thread separation group 6 and separated and divided in the process. After division, the warp threads KF are cut off and presented to a pull-in needle 7, which forms part of the so-called pull-in module.
  • the sectioning device used in the USTER TOPMATIC warp knitting machine (USTER - registered trademark of Zellweger Uster AG), for example, can be used for dividing the warp threads.
  • a monitor 8 which belongs to an operating station and is used to display machine functions and machine malfunctions and for data input.
  • the operating station which forms part of a so-called programming module, also contains an input stage for the manual input of certain functions, such as crawl gear, start / stop, repetition of processes, and the like.
  • the drawing-in machine is controlled by a control module containing a control computer, which is arranged in a control box 9.
  • this control box contains a module computer for each so-called main module, the individual module computers being controlled and monitored by the control computer.
  • the main modules of the drawing machine are, in addition to the modules already mentioned, drawing module, yarn module, control module and programming module, the strand, the lamella and the sheet module.
  • the thread separation group 6, which presents the warp threads KF to be drawn in to the pull-in needle 7, and the path of movement of the pull-in needle 7, which runs vertically to the plane of the stretched warp threads KF, determine a plane in the region of a support 10 forming part of the base frame, which supports the already mentioned upgrade side of the so-called disassembly side of the drawing machine.
  • the warp threads and the individual elements into which the warp threads are to be fed are fed in on the upgrade side, and the so-called Dishes (strands, slats and sheets) can be removed with the warp threads drawn in.
  • the frame 5 with the warp threads KF and the warp beam carriage 2 with the warp beam 3 are moved past the thread separation group 6 to the right, the pull-in needle 7 successively taking out the warp threads KF stretched on the frame 5.
  • the warp thread guard slats LA Immediately behind the plane of the warp threads KF are the warp thread guard slats LA, behind them the healds LI and even further behind the reed.
  • the lamellae LA are stacked in hand magazines, and the full hand magazines are hung in inclined feed rails 11, on which they are transported to the right, towards the pull-in needle 7. There they are separated and brought into the feed position. After pulling in, the lamellae LA arrive on lamella support rails 12 on the dismantling side.
  • the strands LI are lined up on rails 13 and automatically shifted to a separating stage on them. Then the strands LI are individually brought into their retracted position and, after they have been drawn in, onto the corresponding heald frames 14 on the Disarmament side distributed. The reed is also moved past the pull-in needle 7 step by step, the corresponding sheet gap being opened for the feed. After it has been drawn in, the sheet is also on the dismantling side. To the right of the heald frames 14 is a part of the reed WB. This illustration is to be understood purely for illustrative purposes, since the reed is of course located on the upgrade page in the position of the frame 5 shown.
  • a so-called crockery trolley 15 is provided on the dismantling side. This is inserted together with the slat support rails 12, heald frames 14 and a holder for the reed attached to the base frame 1 in the position shown and carries the dishes with the drawn-in warp threads KF after being drawn in.
  • the warp beam carriage 2 with the warp beam 3 is located directly in front of the dishwashing carriage 15. Now the dishes are reloaded from the dishwashing carriage 15 onto the warp beam carriage 2 by means of the lifting device 4, which then carries the warp beam 3 and the drawn-in dishes and to the relevant weaving machine or can be moved to an interim storage facility.
  • the pull-in needle 7, which forms the main part of the feed module, is formed by a gripper band 16 and a clamping gripper 17 carried by the latter.
  • the pull-in needle 7 is guided in the lifting direction (arrow P) in a channel-like guide 18, which extends from the frame 5 in a straight direction to an arcuate end part 19.
  • the guide 18 passes through the drawing-in machine and is interrupted in the area of the tableware organs (lamella LA, strands LI) and the reed WB in order to feed the tableware organs to the drawing-in position and to transport them further after the drawing-in has taken place until transfer (arrow S) to the lamella support rails 12 and to the heald frames 14 (FIG.
  • the gripper belt 16 is provided with equally spaced transport holes and is driven by a motor-driven belt wheel BR, which has cam-like or lug-shaped projections which engage in the transport holes on its circumference.
  • the feeding of the slats LA and the strands LI to the pull-in position and their further transport up to the transfer to the slat support rails or to the heald frames is carried out by a sub-module lamella distribution LD and by a sub-module strand distribution HD.
  • the strand distribution module HD follows in the transport direction of the strands LI to the sub-module strand separation, which is described in Swiss Patent No. 680,933.
  • the lamella distribution module LD follows the sub-module lamella separation in the transport direction of the lamella LA, which is described in Swiss Patent No. 682 576.
  • Both sub-modules HD and LD perform the same functions in principle, by taking over the strands or lamellae offered sequentially, transporting them to their retracted position and, after the warp thread has been drawn in, transporting them to a transfer station, where they are transferred to the heald frames or lamella support rails.
  • the foremost strand LI of a strand stack which lies immediately in front of the submodule HD, is brought out of the strand stack into an intermediate position by a piston-like compartment member and is brought up from this intermediate position by a plunger pushed needle-like holding means.
  • the latter form part of the strand distribution module HD.
  • the lamellae LA are pushed out of their stack a little by a friction roller, so that their head ends protrude freely.
  • a hook mounted on a conveyor belt grips the slats and pulls them completely out of the stack into a transfer station.
  • the free-hanging lamella is blown with compressed air onto appropriate holding means, which form part of the lamella distribution module LD.
  • the strand distribution module HD is shown in FIGS. 3 to 6.
  • 3 shows a plan view on a scale of approximately 1: 2.5
  • FIG. 4 shows a side view in the direction of arrow IV of FIG. 3 on a somewhat smaller scale
  • FIGS. 5 and 6 show a detail on an enlarged scale .
  • the strand distribution module HD essentially comprises two components, transport planes formed by corresponding plates 20, in each of which an endless transport means provided with strand holders is guided.
  • This is designed like a tape, belt or chain.
  • a chain is preferably used as the means of transport, which consists of individual links 22 carried by a toothed belt 21.
  • the toothed belt 21 is provided with teeth on both sides; the toothing on the inside engages with corresponding guide rollers 23, at least one of which is motor-driven.
  • the toothing on the outside of the toothed belt 21 centers the chain links.
  • Each of the chain links 22 has on its side facing away from the toothed belt 21 a projecting, V-shaped rib, at the apex of which a pin 24 designed as a strand holder is anchored.
  • the strands are plugged onto the pins 24 with their end hooks; the mutual vertical distance between the pins 24 and thus the plates 20 is adjustable to match the length of the strands to be processed.
  • a threaded spindle GS is used for this purpose, which engages with threaded locks mounted on the plates 20 of the transport planes.
  • the transfer of the strands to the strand distribution module HD takes place at the points indicated by arrows A, the two arrows symbolizing that the strand separation and their transfer takes place in two channels, which is not absolutely necessary.
  • Sensors 25 for monitoring the wire takeover are present at the takeover points. After the takeover, the strands are transported to the thread feed position by the chain 21, 22 rotating counterclockwise and driven intermittently by a stepper motor.
  • a guide rail 26 is provided between the takeover point A and the thread pull-in position, which prevents the strands from falling off the pins 24.
  • the thread feed path is denoted by a dash-dotted straight line FE
  • the thread pull-in position of the strands is the intersection of their path with the straight line FE.
  • the channel-like guide 18 (FIG. 2) has an interruption through which the strands cross the guide 18. Since the thread eye of the strands is relatively small, the strands for threading must be positioned very precisely. This fine positioning takes place on the one hand in height, that is in the longitudinal direction of the strand, and on the other hand laterally, that is transversely to the longitudinal direction and transversely to the thread feed path FE by appropriate positioning means HP or SP.
  • the height positioning means HP shown in FIG. 4 comprise an endless cable 28 guided over drive rollers 27, to each of which two positioning pins 29 are fastened. When the height positioning means HP are actuated, these positioning pins move up and down and press against the V-shaped ribs of the two chain links 22 to be positioned.
  • the drive for the cable 28 formed by a pneumatic cylinder 30 and the upper drive rollers 27 are on a support arm 31 mounted, which in turn is carried by a carrier shaft 32 passing through the strand distribution module HD. A total of two such carrier shafts 32 are provided.
  • the side positioning means SP which can be seen in particular in FIGS. 5 and 6, are mounted in the region of the channel-like guide 18 on a support 33 which is also fastened to the support shaft 32 carrying the support arm 31 and comprise a transverse guide 34 for the strands, a positioning lever 35 and a control bracket 36.
  • the transverse guide 34 which is arranged just below the channel-like guide 18, has a funnel-like inlet part and then a relatively narrow guide part, in which the strands are guided quite exactly with respect to their lateral displacement.
  • the exact lateral positioning is carried out by the positioning lever 35.
  • This is designed as a two-part gripper. It is driven by a pneumatic cylinder 37 and is moved obliquely from below against the strand to be positioned. In its end position shown in dashed lines in FIG. 5, the positioning lever 35 is closed by the control bracket 36 driven by a pneumatic cylinder 38, as a result of which the strand is clamped and positioned for the thread feed.
  • the heddle is released again by the positioning lever 35, so that it can leave the transverse guide 34 and finally also the guide rail 26 and be transferred to its heddle support rail.
  • This transfer takes place by means of pneumatically driven ejection cylinders 39 arranged in the region of the two plates 21, which can be selectively controlled depending on the distribution of the strands on the individual heald frames, as determined by the pattern to be produced on the weaving machine, in pairs in each case the upper and the lower Ejection cylinder 39 of each strand. As shown, there are 28 upper and lower ones Ejection cylinder 39 is provided so that the strands can be distributed over a maximum of 28 shafts.
  • the lamella distribution module LD is shown, namely in FIG. 7 in a plan view in the direction of arrow III of FIG. 2 on a scale of about 1: 1.5 and in FIG. 8 in a side view in the direction of arrow VIII of FIG. 7.
  • the function of the lamella distribution module LD is very similar to that of the strand distribution module HD.
  • the main differences between the two are that the slats are shorter than the strands, that their thread eye is much larger than that of the strands, so that the requirements for positioning accuracy for the retraction are not so high, and that the number of slat support rails is significantly lower than that of the heddle support rails.
  • the lamella distribution module LD like the heald distribution module HD, contains as a base two spaced plates 40 and 41, the mutual distance of which is adjustable and which serve as a carrier for the various transport and positioning means for the lamella LA.
  • On the upper plate 40 an endless toothed belt 43 is stretched over corresponding gear wheels 42, on the outside of which holding means for the lamellae LA are fastened.
  • the lamellae LA are suspended with their support slot on the support pins 44.
  • the lamellae are transferred to the holding means 44, 45 at the locations indicated by arrows B, the two arrows symbolizing two processing channels of the lamella separation stage.
  • the takeover of the slats from the slat distribution module LD is monitored by sensors (not shown).
  • the lamellae LA are transported from the toothed belt 43, which is moved counterclockwise and intermittently driven by a stepping motor 46, to the thread feed position, which lies in the region of a star-shaped positioning wheel 47 carried by the lower plate 41.
  • a guide rail 48 is provided in the area of the two plates 40, 41 between the takeover point B until immediately after the thread pull-in position in order to prevent the slats from falling off the support pins 44.
  • the channel-like guide 18 passes through the lamella distribution module LD along the dash-dot line FE (FIG. 7) marking the thread feed path in the level between the two plates 40 and 41; the thread retraction position is at the point of intersection of this straight line through the toothed belt 43 on the positioning wheel 47, which is designated by an x in FIG. 8. Then the thread eye FA is aligned with that of the support pins 44 and between the projections of the positioning wheel 47 positioned lamella LA with the straight line FE. In this area, the channel-like guide 18 (FIG. 2) has an interruption in which the slats LA cross the guide 18.
  • the positioning wheel 47 is also driven intermittently, specifically via a toothed belt 49 and a toothed wheel 50, which is fastened on the drive shaft 52, driven by the stepper motor 46 via a toothed belt drive 51, of the toothed belt 43 carrying the holding means 44, 45 for the slats LA.
  • the slats LA After threading in the area of the positioning wheel 47, the slats LA, which now each carry a retracted warp thread, reach the area of a bank-like row 53 of transfer stations, of which a total of 8 are provided according to FIG. 7 in accordance with the number of 8 possible slat support rails 12 (FIG. 1) . Depending on the program, the slats LA are pushed onto the corresponding slat support rails 12 in the transfer stations.
  • the transfer stations consist of an upper and a lower sub-station 54 and 55, each of which is attached to the corresponding plate 40 and 41, respectively.
  • Both sub-stations 54 and 55 each have a pneumatically driven ejector 56 and 57, when actuated, the one in question Lamella LA is pushed onto their mounting rail 12.
  • the upper sub-station 54 is designed in such a way that the slats, when pushed down from the support pins 44, hit with their uppermost edge against an inclined, downwardly inclined guide plane 58 and are thus guided downward, so that they inevitably lead to a correspondingly inclined inlet flank 59 Slat support rails 12 are guided and slide along from this onto the horizontal part of the slat support rail 12.
  • the lower sub-station 55 contains a shaft-like chamber 60 which is open to the front, rear and top and which is separated from the chamber of the adjacent stations by transverse walls 61. Against the toothed belt 43 and the ejector 57, each chamber 60 is closed with a flap 62 in the manner of a double swinging door. This serves as a safeguard against inadvertent falling of the slats LA from the support pins 44 as a result of the tensioning force of the drawn-in warp threads.
  • the ejector 57 When the ejector 57 is activated, it opens the flap 62 and pushes the lamella LA on its lower part into the chamber 60; at the same time, the upper ejector 56 pushes the lamella from its support pins 44 against the guide plane 58 onto the inlet flank 59 of the lamella support rails 12.
  • the latter are held in the transfer position by spacer plates which can be displaced in the longitudinal direction of the rail; the spacer plates are transported along the slat support rails when they are moved 12 the slats further.
  • the lamella support rails 12 are held horizontally by holding bolts which can be moved in and out and are fastened to a transport system. In their retracted position, they position the slat support rails 12, and they are extended to pass the slats at the relevant point.
  • Both the strand and the lamella distribution module HD or LD are provided on their upper plate 21 or 40 with corresponding cover hoods, which on the one hand cover the entire mechanics and protect them from dust, and on the other hand have connections for the required pneumatic and electronic lines.
