Definitions

  • the invention relates to a device for temporarily storing yarn with a belt conveyor with a drive device, a winding head with a thread guide guided on a circular path, through which the yarn is placed in the form of loops in the manner of a helical coil on the belt conveyor at its front end in the transport direction, one Mast with essentially extending in the longitudinal direction of the mast, arranged around the mast conveying means onto which the twine loops can be placed by the winding head in such a way that during operation of the device the mast is at least part of its length within the twine loops, with a Device for pulling the yarn at the rear end of the belt conveyor, wherein a drive member movably driven in the direction of movement of the belt conveyor is provided for driving the belt conveyor, which is in frictional contact with the conveyor belt of the belt conveyor or with a drive part coupled to the latter, the movement g Speed of the drive member in the transport direction of the belt conveyor corresponds approximately to its transport speed.
  • Such a device is essentially known from DE-C-2 040 361.
  • a shaft which drives the thread guide directly is inserted into the interior of a housing which is part of the belt conveyor and which is rotatably mounted on the shaft.
  • the housing contains a worm gear gear drive which is driven by the rotating shaft and drives V-belts which in turn drive the conveyor belts of the belt conveyor.
  • the V-belts lie on the inside of the conveyor belts, whereas the loops are placed on the outside of the conveyor belts.
  • support rollers arranged outside of the loops and supported on a stationary machine frame lie against the conveyor belts in the region of the V-belts, the support rollers being rotated by the conveyor belts through the plane defined by the loops through frictional contact and the V-belts are supported at this point by counter pressure rollers arranged on the housing.
  • the invention has for its object to simplify the device described above, which requires a gear transmission within the belt conveyor.
  • the drive member is arranged outside the loops and is coupled through the surface defined by the loops to the conveyor belt or to the drive part coupled to the belt conveyor.
  • DE-A-1 813 246 a device for the continuous treatment of yarns which has a belt conveyor with a mast arranged inside it, the yarn being placed on the belt conveyor in the form of loops by a thread guide and is transported through this and is withdrawn at the other end.
  • the conveyor belts of the belt conveyor are driven by a shaft moving the thread guide via a gear of the belt conveyor.
  • the lower conveyor belts are offset towards the central mast, so that the yarn loops hang freely in this area.
  • the mast has a rail with a concave, circular-arc-shaped path, on which the arms of a star-shaped, machine-mounted, driven support wheel with rollers arranged at the end of the arms can be supported.
  • the support wheel should reach through with the ends of its arms between adjacent free hanging loops so that the roller at the end of each arm only comes into contact with the rail and can support the mast without disturbing the yarn.
  • the jockey wheel is not used to drive any parts of the belt conveyor.
  • the advantage of the invention lies in the fact that no gear transmission arranged in the area of the anchoring of the mast of the belt conveyor is necessary, since in the simplest case the driving force for the conveyor belt is transmitted directly to it. Since any speed difference that occurs between the belt conveyor and the drive member is relatively small, it does no harm if the loops placed on the belt conveyor come into physical contact with the drive member. If the drive member is in direct contact with the conveyor belt, apart from a possible slip, there will generally be no speed difference; however, a speed difference between the drive member and the driven part is possible if, as will be explained later, the drive member is in contact, for example, with a drive roller arranged within the area defined by the loops.
  • the rotatingly driven drive member can in particular be a wheel.
  • it could also be designed in the manner of a conveyor belt which engages essentially over its entire length with the run of the conveyor belt of the belt conveyor which holds the loops.
  • wheel is also to be understood here to mean a roller, that is to say a wheel with a considerable thickness measured in its axial direction.
  • the wheel is coupled to a friction wheel arranged in the interior of the loops and in driving connection with the conveyor belt.
  • the contact zone between the wheel and the friction wheel is preferably approximately in the area defined by the loops.
  • the wheel is in contact with the conveyor belt and the conveyor belt is supported on its side facing away from the wheel in its area.
  • the wheel can exert a sufficiently strong contact pressure against the conveyor belt in order to drive it securely by means of frictional forces.
  • the peripheral speed of the wheel is the same as the transport speed of the conveyor belt except for one slip, so that the position of the loops of yarn between the wheel and the conveyor belt is not or hardly changed.
  • the only interference that is exerted on the yarn is a brief pinch between the conveyor belt and the wheel (or the friction wheel and the wheel in the embodiment described above), but this brief compression does not affect the yarn or only to a completely negligible extent .
  • the belt conveyor is rotatably mounted about its longitudinal axis and a support is provided in the area of the loops to prevent rotation of the belt conveyor about its longitudinal axis, said support having at least one support wheel, the axis of rotation of which runs transversely to the conveying direction of the belt conveyor
  • the rotatably drivable wheel simultaneously forms the support wheel.
  • the rotating drivable wheel can be located anywhere within the length of the belt conveyor.
  • the rotating drivable wheel which also serves as a support wheel, can also at least partially bear the weight of the belt conveyor.
  • the drive wheel can expediently be designed as a drive roller and be located in the region of the rear end of the belt conveyor in the conveying direction.
  • the device described can be used particularly advantageously in a texturing device for yarn, in which the yarn is first fed to a texturing device, in particular an air texturing device, and then to a temperature treatment for fixation.
  • This temperature treatment takes place on the device described above, which is surrounded for this purpose by a housing in order to maintain the desired temperature in the region of the yarn loops.
  • the particular advantage of the use is that a considerable dwell time of the yarn in the area of the heat treatment can be achieved with a relatively short overall length of the device, so that the texturing can be securely fixed.
  • the device shown in FIG. 1 comprises a winding head 1, to which a belt conveyor 2 connects, which leads through a treatment zone 3, which is delimited by a housing 4 indicated by dash-dotted lines and enclosing the treatment zone.
  • a winding head 1 to which a belt conveyor 2 connects, which leads through a treatment zone 3, which is delimited by a housing 4 indicated by dash-dotted lines and enclosing the treatment zone.
  • the yarn placed on the winding head 1 is drawn off via a draw-off ring 5.
  • Two light barriers 6, 7 and 8, 9 ensure that the end of the winding winding of the yarn on the belt conveyor 2 remains constantly in the area between these light barriers; the withdrawal speed is regulated accordingly in order to achieve this goal.
  • the winding head 1 has a support tube 11 which is rotatably held by means of a support tube 13 which is rotatably mounted about a horizontal axis in a bearing 12, the left end of the support tube 11 being exactly in the axis of rotation, and the right end being bent out of the axis of rotation and is held by a holding disk 14 rotating with the holding tube 13.
  • the yarn, not shown in Fig. 1 is blown into the support tube 11 through a blow-in tube 15 and from this, during its rotational movement, placed on the belt conveyor in the form of loops which take the form of a helical winding due to the simultaneous transport movement of the belt conveyor.
  • the belt conveyor 2 has a horizontally lying central mast 18, which is formed by a tube, the left end in Fig.
  • the support tube 11 is driven in the manner indicated via a belt drive 23, which transmits the rotary movement of a drive shaft 24 to a wheel 25 connected to the support tube 11.
  • the belt conveyor 2 has two conveyor belts 30 and 30 ', which are laid one behind the other in the same way in the viewing direction of FIG. 1, so it is sufficient to explain the course of the belt 30.
  • This runs from a front lower roller 31 slightly rising to a rear lower roller 32, in which it is deflected and runs back above the belt section just described, is guided around a roller 33 by approximately 270 °, which is behind in the viewing direction of FIG. 1 the level of the roller 32 is located. From the roller 33, the belt moves upwards to a roller 34, which is again somewhat further back in the direction of view in FIG.
  • roller 34 and the corresponding roller 34 'belonging to the band 30' are fastened to a block 40 which is directly connected to the mast 18 and carries downward projecting extensions 41 on which the rollers 33 and 33 'are rotatable are attached.
  • a friction wheel 45 is connected coaxially and in a rotationally fixed manner, which extends with its circumference on its underside into the plane running through the two sections of the belts 30 and 30 'running between the lower rollers 31 and 32.
  • a roller-shaped wheel 50 presses against this friction wheel 45 from below, which is mounted in a fixed manner in the manner indicated and can be driven via a pulley 51.
  • the wheel 50 is so long in the direction of its axis of rotation, which runs perpendicular to the plane of the drawing in FIG. 1 and thus horizontally, that it is both with the friction wheel 45 of the conveyor belt 30 and with the friction wheel 45 'of the conveyor belt arranged in mirror image with the friction wheel 45 30 'is engaged.
  • the mast which is rotatably mounted with its left end in FIG. 1 in the holding disc 14 or the belt conveyor connected to it is prevented from rotating about its horizontal longitudinal axis.
  • the friction wheels 45 are pressed against the wheel 50 by the weight of the belt conveyor 2, insofar as this is not received by the bearing 12.
  • the frictional force between the wheel 50 and the friction wheels 45, 45 ' is so great that the rotational movement of the wheel 50 sets the friction wheels 45, 45' and thus the conveyor belts 30, 30 'in motion.
  • These loops of thread run between the friction wheel 45 and the wheel 50 in the transport direction of the belt conveyor.
  • the diameter of the friction wheel 45 is approximately as large as that of the roller 33, so that the peripheral speed of the wheel 50 corresponds to the transport speed of the belt conveyor.
  • the mast is also supported by the wheel 50 at its end region on the right in FIG. 1, in contrast to known devices, it does not have to be self-supporting and can therefore be manufactured very easily and with low weight. Since the described support, which leaves the end of the belt conveyor free, it is also possible to pull off the yarn by means of a simple pull-off ring 5.
  • the rear rollers 32 and 36 are mounted on two-armed levers 55, so that they can be adjusted inwards or outwards by means of an adjusting screw 56 screwed onto the end of the mast 18 (in FIG. 1, this is approximately perpendicular in the direction) can be pivoted up or down) in order to thereby tension the conveyor belts or to adjust the directions of the conveyor belts between the rollers 31 and 32 or 35 and 36 which deviate slightly from the horizontal.
  • the device described above is part of a texturing machine.
  • the yarn 60 runs from a supply spool 61, which is stored in a creel 62 with numerous supply spools, via a plurality of thread guides 63, 64, 65 to a delivery unit 66, from where it arrives at the texturing nozzle 67.
  • This nozzle is contained in a housing that is visible in FIG. 4.
  • the yarn arrives via a delivery mechanism 68 to the blow-in tube 15 of the yarn store described with reference to FIGS. 1 and 3, which is part of a fixing chamber in which the textured yarn is fixed.
  • the individual yarn loops on the belt conveyor are indicated in FIG.
  • the yarn is drawn off at the end of the belt conveyor via the rigid take-off ring 5 and runs over belt guides 71, 72, 73 and 74 to a winding device 75.
  • the further delivery mechanisms and winding devices as well as supply spools visible in FIG. 4 are connected to further fixing chambers which are arranged behind the shown fixing chamber and are not specifically shown.
  • the yarn store with the belt conveyor 2 and the housing 4 is fastened to the upper end of a machine frame 78, in which the individual elements of the texturing machine just mentioned are arranged. Because of its low weight, the yarn store can be accommodated without difficulty at the point shown, an operating aisle being left between the supply spools 61 and the described delivery mechanisms, which is carried out via an operation 80, below which the yarn passes between the deflections 72 and 73 can be.
  • the shaft 24 and the wheel 50 are driven by a belt 76A or 76B by a drive motor 77A or 77B, each of which is on a platform 79A or 79B.
  • the winding device 75 is designed for winding a cone coil.
  • the device described is particularly suitable for processing a yarn of this type which has a burdock effect, that is to say adheres more or less strongly to sections of the same yarn.
  • the device can be operated in such a way that the individual thread loops do not touch each other on the conveying device, so that operation cannot be disrupted by the above-mentioned burdock effect.
  • the term belt conveyor is also to be understood to mean a device in which a rope or a rope-like conveying means is provided instead of a conveyor belt.
