Definitions

  • the invention relates to a device for depositing a cable consisting of synthetic threads in helical windings, in particular in cans, according to the preamble of claim 1.
  • the invention is based on a storage device which has become known from FR-PS 11 34 129 ( Figure 5). Toothed disks are provided as conveying members. These mesh directly with a snail that sits on the main shaft. This device is unsuitable for the vast majority of applications. Lubrication of the worm drive is inevitable at the main shaft speeds of 1,000 to 5,000 revolutions per minute that are common today. The lubricant would adhere to the toothing of the conveyor disks and contaminate the cable that is inserted directly into the toothing in an unbearable manner.
  • the toothing must ensure sufficient running properties of the worm gear
  • the tooth shape must be designed in such a way that the cable is guided precisely and is released without damage.
  • a change in the conveying speed requires the exchange of worm and toothed lock washers and is only possible in a very limited area.
  • Another storage device is known from DE-OS 28 09 661 ( Figure 1).
  • Several endless belts are provided as conveying members, each of which rotates via a drive roller and a deflection roller.
  • An unspecified gear is arranged laterally under the winding body and has a vertical, i.e. shaft parallel to the system axis, which is coupled to the main shaft by a belt.
  • the gearbox On the output side, the gearbox has a horizontal shaft, which is connected to the drive roller of one of the conveyor elements via a further belt drive.
  • the drive rollers of the other conveying members are to be driven in an unspecified manner by elastic shaft, bevel gears or the like from the drive roller mentioned, since it is obviously not possible with the bulky gear arrangement to couple all drive rollers individually directly to the gear.
  • the arrangement of the gear under the winding body means an unfavorably large drop height for the cable windings; This can make the orderly filing difficult. If e.g. is placed in a jug, which rotates eccentrically to the system axis in the usual way, then depending on the speed, the falling cable turns, which are pulled by the rotating jug, can get caught on the parts protruding downwards.
  • a depositing device which is described in DE-AS 27 47 706, has, in addition to the inner conveying members distributed over the circumference of the winding body, outer conveying members which are arranged in an annular outer body surrounding the winding body.
  • the outer conveying members are driven and drive the inner conveying members of the winding body by friction.
  • the cable turns run between the inner and outer conveying members and are exposed to the contact pressure required to generate the frictional force. Therefore, this device is not suitable for cables that are sensitive to crushing.
  • the drive of the outer conveyor elements is not shown in the mentioned DE-AS, but is outlined in the corresponding US-PS 43 04 366 as a bevel gear drive.
  • the inventor has set himself the task, while avoiding the disadvantages of the prior art, to equip a device of the type specified in the preamble of claim 1 with a compact design with a gear for the conveying members, which is suitable for continuous operation at high rotor speeds and the designer with regard the design of the conveying bodies leaves ample scope for optimal adaptation to the procedural requirements of the respective application.
  • the gear is in the spaces that are present with an optimal (namely radial) arrangement of the conveying members; it does not require the winding body to be enlarged.
  • the gear functions and the functions of the conveyor elements are independent of each other.
  • the lubrication of the gearbox does not contaminate the conveying elements.
  • the gearbox can be optimally designed, i.e. in particular with optimal gear teeth.
  • the conveying speed of the conveying elements can be changed by exchanging the gear elements without an exchange of the conveying elements being necessary.
  • the surfaces of the conveying elements that come into contact with the cable can be designed regardless of the gear unit.
  • the embodiment of the first gear stage specified in claim 2 combines the advantages that it runs without slip and requires no lubrication.
  • the substantially rotationally symmetrical - depositing device 1 the vertical geometric axis of which is hereinafter referred to as the "system axis" is attached to an arm 2 which is angled downwards.
  • This arm is connected in a machine frame 3 to a vertical lifting device 4, which, for example to be operated hydraulically, pneumatically or via a driven threaded spindle.
  • a godet 5 is mounted on the machine frame 3 above the depositing device 1.
  • a rotary plate 7 is fastened to a base plate 6 of the machine frame 3 and a gear can be rotated about its eccentric axis to the system axis.
  • On the turntable 7 is a jug 9 with approximately the same diameter.
  • the device 1 has a cap 10 open at the bottom, which is firmly connected to the arm 2, not shown in FIG.
  • a motor 11 On top of the cap 10 there is a motor 11 with a hollow shaft 12, the geometric axis of which coincides with the system axis.
  • a coaxial tube 13 In the hollow shaft 12 there is a coaxial tube 13, the upper end of which is fixed immovably in a bore of a head plate 14 screwed to the upper side of the motor 11.
  • a nozzle plate 15 On the head plate sits a nozzle plate 15, the inlet opening 16 opens into the tube 13.
  • the inlet opening 16 is surrounded by a concentric annular channel 17 which has a compressed air connection 18 and is connected to the interior of the tube 13 via an annular nozzle-like narrow gap.
  • the elongated lower end of the tube 13 opens into a tube 19 which extends obliquely downwards in the direction of the outer surface of the cap 10 and has an extension 20 which bends downwards in the vicinity of the outer surface.
  • the pipe train consisting of parts 13, 19, 20 is referred to as a "flyer”.
  • the tube 19 is fixedly connected to a rotor 21 which is screwed to a flange 22 seated on the hollow shaft 12 and can be rotated relative to the tube 13 by means of a ball bearing 23.
  • a downwardly directed main shaft 25 which is rotatable about the system axis is fixedly connected to the rotor 21 by a flange 24 and, for constructional reasons, consists of two shaft pieces 25a and 25b connected by a plug-in coupling 26.
  • An essentially cylindrical bobbin 31 is supported on the main shaft 25 with ball bearings 27, 28, 29, 30.
  • the jacket of the winding body consists of an upper part 32 and a lower part 33 releasably inserted therein, the diameter of which is slightly smaller than that of the upper part.
  • the bottom 34 connected to the lower part 33 lies only a little below the lower edge of the hood 10.
  • Four circular disks 35 are mounted inside the winding body as conveying members. These disks lie in vertical planes that are radial with respect to the system axis and offset by 90 ° to one another. The diameter of the disks is a little smaller than the radius of the winding body 31 and, apart from the required play, corresponds to the clear height of the winding body 31.
  • Each disc 35 protrudes outwards with a narrow segment through a slot 36 in the jacket 32, 33.
  • the disks 35 can be rotated about horizontal axes with a gearbox described in detail below, which — compared to the disk radius — lie a little below the circumferential plane of the mouth of the tubular extension 20.
  • the disks are spherical on the circumference.
  • a pressure roller 37 is assigned to each disc 35.
  • the pressure rollers are loosely rotatable on rockers 38.
  • Each rocker 38 is hinged at its upper end to a tab 39 which is fastened to the inner surface of the hood 10 approximately at the level of the axis of the disks 35.
  • a spring 40 supported on the lower edge of the hood 10 presses against the free lower end of the rocker 38, the contact pressure of which can be adjusted by means of a screw 41.
  • the diameter ratio between pressure rollers 37 and discs 35 is approximately 1: 3.
  • the point of contact between the pressure roller 37 and the disk 35 lies below the axis of the disk 35 at a distance which corresponds to approximately half the disk radius.
  • the pressure rollers 37 have a thick rubber coating 42 on the circumference, which - corresponding to the spherical circumferential surface of the disks 35 - has a channel-like profile, as can best be seen from FIG.
  • toothed disks 43 are provided as conveying members.
  • the peripheral toothing 44 is interrupted by a circumferential groove 45.
  • Counter rollers 46 engage in the groove 45 and are arranged essentially like the pressure rollers 37 of the other exemplary embodiment.
  • the counter rollers 46 can bear against the base of the groove 45 under spring force. However, they can also be set at a distance by means of a simple adjusting screw, as indicated in FIG. 6. In this position, which is provided in particular for the laying down of cables made of material sensitive to crushing, the pressure rollers 46 engage in the groove 45 without touching the cable.
  • the exemplary embodiment according to FIG. 7 differs from the exemplary embodiment illustrated in FIGS. 5 and 6 in that, instead of the counter roller 46, there is a fixed tab 47 which engages in the groove 45 but does not reach the bottom of the groove. In simple cases, it is sufficient to assign such a tab to only one toothed pulley 43.
  • the characteristic features of the invention are embodied on the transmission which couples the conveying members (disks 35 or toothed disks 43) to the main shaft 25.
  • This gear is completely housed in the winding body 31 without the need to enlarge the winding body.
  • the one in the Preferred embodiment shown in the drawing even suffices only two of the four rectangular sectors located between the conveying members for the accommodation of the transmission.
  • a gear shaft 51, 51 'parallel to the main shaft 25 is mounted in each of the two bearing housings 49, 49'.
  • the two gear shafts are offset by 180 ° with respect to the system axis.
  • gear wheels 52, 52 ' which are coupled via toothed belts 53, 53' to a toothed sleeve 54 fastened to the main shaft 25.
  • the toothed belt 53 wraps around the upper part of the sleeve 54, the toothed belt 53 'around the lower part.
  • a worm drive is located in each bearing housing 49, 49 'as the second gear stage. In Figures 3 and 4, the worm gear is shown only for the bearing housing 49.
  • a worm 57 On the gear shaft 51 sits between the ball bearings 55, 56 with which the gear shaft 51 is mounted in the bearing housing 49, a worm 57. With the worm 57 mesh two worm gears 58, 58 ', which are on the drive shafts 59, 59' of the two enclosing sector 48 between them. Discs 35 sit.
  • the drive shafts 59, 59 ' are also mounted in the bearing housing 49.
  • the second gear stage for the two disks, which enclose the sector 48 ', is designed to be completely identical.
  • the disks 35 and the various gear elements are easily detachably attached to the associated shafts so that an exchange is possible in a short time.
  • the exemplary embodiments described are particularly suitable for cables with a relatively low titer between 500 and 5000 dtex, which are drawn off at speeds of 1000 to 5000 m / min and placed in cans, the cable tensions being kept below 1 g / dtex.
  • the device operates as follows: A cable 60 is fed via the godet 5 essentially along the system axis. Only when the cable is inserted is the connection 18 pressurized; The compressed air is switched off in stationary operation. If necessary, air with a slight overpressure of 0.1 to 0.5 bar and high relative humidity is supplied for the purpose of discharging electrostatic charge during continuous operation.
  • the cable emerging from the lower end of the flyer is placed around the non-rotating bobbin 31.
  • the disks 35 which are coupled to the rapidly rotating main shaft 25 by the transmission described, rotate slowly in the direction of the arrows 61, 62, i.e.
  • the windings placed slightly above the disc axes are first slightly tensioned, taken down by the discs 35 and passed between the discs 35 and the pressure rollers 37.
  • the pressure rollers 37 have a dual function: by the form-fitting engagement on the spherical peripheral surfaces of the disks 35, they prevent the winding body 31 from rotating as well. In addition, they cause each turn only at the moment when they reach the point of contact between the disk 35 and the pressure roller 37 happened, is released.
  • the lower lateral surface 33 of the winding body 31 serves as a guide for the falling turns and prevents their undesired deformation. As a result of the reduced diameter, however, it does not exert any appreciable frictional forces on the falling turns.
  • the free fall height must be kept low. Therefore, the device 1 is at the start of operation in the position indicated in FIG. 1 with dash-dotted lines. As the filling progresses, it moves steadily upward, so that the bottom 34 of the winding body 31 is always just above the top filling layer. A loose filling is formed from which the cable can be pulled off without interference.
  • the circumference of the winding body 31 is approximately 1 m. It rotates at a speed of 3000 rpm.
  • the disks 35 rotate at a speed of 100 rpm. Its circumference is 40 cm. Therefore, their downward conveying speed is 40 m / min. The distance between two successive turns is therefore 1.32 cm.
  • the speed of the toothed disks 43 must be matched to the number of teeth so that the cable turns are inserted exactly into the tooth gaps.
  • the speed at which the cable is fed is again 3000 m / min.
  • the circumference of the winding body is 1 m, ie its speed is 3000 rpm.
  • the distance between two adjacent tooth gaps is 1 cm, the number of teeth 40, the circumference 40 cm.
  • the peripheral speed of the toothed pulleys must be 30 m / min. This results in a speed of 75 rpm for the toothed disks 43.
  • the gearbox is designed accordingly.
