Definitions
- the invention relates to a device for producing a Cable stranding with changing direction of lay from single wires, with washers with holes to accommodate the stranded Single wires, being between one with alternating Direction of rotation driven washer and a wire inlet side, fixed guide disc several rotatably mounted Storage disks are located and being each storage disk a stop is associated with an adjacent one Disc-assigned stop for limiting the differential angle cooperates.
- Short acceleration times are, however, for good stranding quality indispensable, so that short swirl change points on the finished Rope can be achieved.
- the achievable working speed the shorter the shorter the stranding system are the acceleration times (turning times).
- WO 94/20969 A1 describes a generic device for Establish a cable stranding known in the in the storage section
- Storage disks in tubular torsion chain links are stored. Are on these torsion chain links rigid stops are provided, via which the tubular Torsion chain links and subsequently also the storage disks have a differential angle limitation to each other.
- the invention has for its object a generic To provide the device with which, if possible low technical effort, short acceleration times Discs can be reached when changing the direction of rotation.
- this object is achieved in that the Storage disks can be rotated freely in fixed bearings are that a stop is assigned to each storage disk, the stop associated with each adjacent disc interacts to limit the difference angle, and that at least part of the stops is elastic.
- the storage disks are in their bearings freely rotatable and without a direct or central drive are essentially carried along by the wires to be stranded.
- the storage disks only have stops that prevent that, if necessary, the wires between two storage disks too strong, namely e.g. more than a difference angle of about 180 °, turned in one direction or the other become what hinder or slow down the passage of the veins would. With this arrangement it is achieved that the washer can change their direction of rotation without in their acceleration phase hindered by the inertia of the storage disks to become.
- At least some of the stops are resilient, so energy-saving, executed. Also a damping version is possible.
- one stop can be used on each storage disc as e.g. made of spring steel Stop rod run with a non-resilient Stop interacts with the adjacent storage disc.
- the resilient stop rods are elastically bent, that is curious; excited. Initially, this causes the Storage discs up to the washer, as well as the motor, which drives the washer, and then an acceleration the washer and the storage disks in the new direction of rotation regardless of the drive motor that this movement however supported. Because the drive motor during acceleration but is not fully loaded by the panes, it can accelerate very quickly, after which the disc and the drive motor through the storage disks over the stops again be burdened additionally.
- the turn direction of the stranding produced this makes it very short.
- the stored can be optimally designed Spring energy should therefore be so large that it can be used during the short Acceleration phase, the washer in addition to the acceleration torque the engine accelerates so that the turning point better on the finished rope, i.e. shorter, is trained.
- resilient stops On Another advantage of resilient stops is that the disc drive "overturn" in the springy area (e.g. by Mass inertia at high speeds), without interference or Causing damage to the stops while taking but it prevents the veins between two storage disks can be screwed in by more than 180 °, which through a suitable dimensioning of the spring characteristic of the Attacks, possibly in conjunction with an additional fixed stop, can be achieved.
- each storage disc and the washer a counter gear is connected upstream, which with its associated Storage disk connected if necessary via a gear and that the stops are arranged on the counter gears are.
- the storage discs and the washer are in Type of countershaft with countershaft wheels "gear-like" connected to each other via the stops.
- you can the storage disks with the counter wheels e.g. about Belt transmission, primarily with fast translations (i.e. the counter gear rotates slower than the storage disc), be connected.
- a gear ratio between the counter gear and the storage disk has the advantage that in the interaction of spring hardness and a suitable choice of gear ratio the spring properties may be better suited to the desired design of the ropes of the stranding machine to be produced can be.
- Fig. 1 shows schematically in longitudinal section a device according to the invention
- Fig. 2 shows a section through the device of Fig. 1 along line II-II.
- a device points to a machine frame 15 a series of stands 12, e.g. fifteen on those Storage disks 4 and a washer 5 in bearings 9 free are rotatably mounted.
- a series of stands 12 e.g. fifteen on those Storage disks 4 and a washer 5 in bearings 9 free are rotatably mounted.
- On the inlet side is 12 on the first stand a fixed guide plate 3 attached.
- disks 3, 4, 5 are a central bore 11 for a center wire 2, and in the radius around the center hole 11 around holes 10 (four in the present exemplary embodiment) provided by which the individual wires to be stranded 1 are led.
- the laying disc 5 arranged on the outlet side of the device is driven by a motor 6 via a V-belt 7, the V-belt 7 on the one hand around a toothed flange 16 the washer 5 and on the other hand a pinion 17 on the drive shaft of the motor 6 is guided.
- the motor 6 drives the Disc 5 with revolutions between about 2000 and 4000 U / min, with about two changes of direction per second are to be carried out. It can make about 10 to 25 beats each Direction on the finished rope.
- a guide nipple connects to the washer 5 8 with a hole in which the individual wires 1, 2 are brought together become.
- Storage disks 4 are essentially only from the wires or individual wires 1, 2 to be stranded or rotated and therefore have no direct drive.
- stops 13 on the disks 3, 4, 5 and 14 arranged which represent the difference angle, i.e. that Angle to the adjacent discs 3, 4, 5 against each other can be twisted, limit.
- a fixed stop 14 is arranged on one side and on the opposite side one made of spring steel manufactured stop rod 13, which with the fixed stop 14th the adjacent storage disk 4 or guide disk 3 interacts and the difference angle to the adjacent disc 3, 4 limited to a little under 180 °.
- the angle can also be not equal to 180 ° (in the present Case reduced by the width of the stops 13, 14), in particular be less than 180 °.
- the laying disc 5 is rotated by the motor 6 so far until all stop rods 13 on the assigned Stops 14 abut, either by the moment of inertia the disks 4, 5 and the motor 6 or through targeted longer driving the motor 6 a bias in the stop bars 13 is generated. Then the engine 6 accelerated in the opposite direction, so the Tension in the stop bars 13, the washer 5 also accelerates in the opposite direction so that the drive motor 6 is relieved and also accelerate very quickly can.
- the Spring characteristic of the stops 13 is not continuous, e.g. progressive or with a kink, so that after the Attacks 13 have stored sufficient energy very rapid braking of the storage disks 4 to Placement disc 5 and the drive motor 6 takes place and thus a Turning the individual disks 3, 4, 5 against each other a predetermined angle is reliably prevented.
- the permissible spring travel of the stops 13 is preferred designed so that the sum of the spring travel of all elastic Stops 13 corresponds approximately to that angle of rotation for the Acceleration of the washer required when changing the direction of rotation becomes.
- the device according to the invention extremely rapid reversal of the direction of rotation of the disk 5 is achieved, which is essential for a short turning point on the finished rope is, at the same time overturning the individual Disks 3, 4, 5 against each other over a predetermined angle is prevented.
