Definitions

  • the invention relates to a method for depositing continuous material running in one plane, in which the endless material is deformed on the surface of a rotating wheel provided with deflecting bodies arranged on its circumference for meandering and then deposited.
  • Such methods and devices are used, for example, in the production of synthetic staple fibers if the sheets of thread drawn off from a large number of melt spinning nozzles are combined to form a spinning cable and are then placed in large spinning cans.
  • a filing procedure for spinning cables has to reduce the speed of the delivered spinning cable before it is placed in the spinning can, otherwise the high impulse of the spinning cable must be destroyed immediately when it hits the mass already deposited, whereby the spinning cable opens and splices, which leads to tangles and tangles of the filaments.
  • the spinning cable is pulled out of the spinning can again, this leads to leakage problems and filament damage and to uneven stretching, which can be found in different textile technology data, e.g. Show differences in staining. In the worst case, the spun cord can be damaged so severely on impact in the spinning can that it cannot be processed further.
  • This necessary speed reduction can e.g. by a sinusoidal deformation using a pair of profile rollers.
  • the present invention is intended to avoid these disadvantages, i.e. do not require coordination of a pair of profile rollers and enable the formation of meanders over a larger angular range; but the advantages of the roller with periodically arranged deflection pins or teeth should be fully retained.
  • this takes place in a method of the type mentioned at the outset in that the deformation takes place with a single wheel; that catch elements are located between the deflecting bodies, which swivel into this plane from outside the plane of the continuous material and deform the continuous material into meanders when moving inwards; and that the catching elements then swivel out again from the plane of the running endless material and thus release the meandering deformed endless material for storage.
  • the movement of the catching elements is preferably controlled by mechanical means.
  • each catch element slides through a fork in a guide groove in the wheel, the fork being fastened to the wheel via a first joint, a connecting rod and a bearing block.
  • the catch element is moved via a second joint by means of a push rod.
  • the push rod runs in a push rod guide, the movement sequence of the push rod being determined by a cam disc via a cam roller.
  • deflection pins 2 are arranged uniformly on the circumference as deflection bodies 2 in the example shown.
  • These deflecting bodies 2 are essentially parallel to the axes of the wheel 1. However, they can also have an inclination of up to approximately 15 ° to the axis or away from the axis.
  • These deflecting bodies 2 have circular cross sections here. They can be designed as a solid body or as a hollow body. In the example shown, the deflection bodies 2 are rigidly attached to the wheel 1, and they can also be rotatably mounted. Their surface is usually wear-resistant det. The width of this deflecting body 2 is adapted to the respective device and the continuous material 15 to be deposited.
  • the deflecting body 2 in the device used according to the invention can, however, also be designed as ribs running radially to the center of the wheel, while in the case of the profile roller pair according to EP-A-0009162, only pins with a small radial extension may be used in order to enable a large engagement. As the wheel diameter increases, more deflection pins can be attached, thus increasing traction and engagement.
  • a catch element 5 can slide through a fork 4 in each of these guide grooves 3.
  • the catch member 5 is attached via a first joint 6 to a connecting rod 7, which in turn is rotatably attached to the bearing block 8, which is attached to the wheel 1.
  • the catch element 5 swivels from the right into the thread running plane 9 and at the same time moves radially inwards in the direction of the axis of the wheel 1.
  • This movement of the catch element 5 is brought about by a push rod 10 which also has a second joint 11 the catch organ 5 is connected.
  • the push rod 10 carries at its other end a cam roller 12 which runs in a standing cam 13 when the wheel 1 rotates. The cam 13 thus controls the movement of the catching element 5.
  • the catching element 5 is usually shaped like a hook, so that it moves the continuous material 15 radially inwards when penetrating into the thread running plane 9.
  • this catch element is designed to be rotationally symmetrical, but need not be rotationally symmetrical.
  • It can be formed as a solid or hollow body and can be rigidly attached or rotatably mounted. Its surface is also usually made to be wear-resistant.
  • the cam roller 12 is pressed against the cam disk 13 by the centrifugal force when the wheel 1 is rotating.
  • the cam roller 12 can also preferably be pressed onto the cam disk 13 by springs or pneumatic or hydraulic means.
  • the cam roller 12 can also be replaced by a sliding block, which then runs in a corresponding cam track.
  • the shape of the cam 13 is constructed point by point according to the requirements of the respective system.
  • the wheel used according to the invention causes a meandering of the continuous material 15 and thus a corresponding reduction in speed.
  • the first placing of the continuous material 15 on the storage member causes great difficulties in the pair of profile rollers according to the prior art.
  • the delivered continuous goods e.g. a spinning cable, brought tangentially to the rotating wheel 1 when starting.
  • the spinning cable is now gripped by a catch element 5 and, during the rotation of the wheel 1 by an angle d, the size of which is determined by the course of the cam disk 13, is pulled inward and deformed in a meandering shape.
  • the spinning cable is now transported in a meandering shape over the angular range ⁇ .
  • the distance between the deflection body 2 and catch element 5 corresponds to the engagement of the pair of profile rollers according to EP-A-0009162.
  • the catch element 5 swings out again from the thread running plane 9 and thus releases the meanders, which are then deposited in the spinning can at a reduced speed in accordance with their deformation.
  • the meander formation i.e. the pivoting of the catch element 5 from the position shown in dashed lines outside the thread running plane 9 into the solid drawn inner position of the catch element 5 can take place over a relatively large circular arc if, for example, 1 puts the spinning cord on the lower end of the wheel 1 and transports it over 270 ° with the wheel 1.
  • the sketched device used according to the invention is not balanced since masses move relative to the center point of the wheel during the movement of the catching elements 5 and the wheel 1. This imbalance can be reduced or eliminated in a manner known per se by suitable shaping of the fork 4 and the connecting rod 7. These components must be shaped in such a way that the center of gravity of the moving components is retained during the movement by the push rod 10.
  • the method according to the invention is particularly suitable for depositing fiber cabins obtained during rapid spinning.
  • the wheel used according to the invention allows a strong meandering (engagement) of the supplied endless material and thus a large reduction in speed.
  • the endless material is then transported in a meandering shape. This results in a uniform tension between the delivery member and the storage member.
  • even high stresses in the endless material blank such as a tow achieve, so that the present invention Rad used directly, can be disposed without further delivery member according to the spinning nozzle so as to perform a g alettenloses spinning fiber cables.
  • the wheel used in accordance with the invention with catching elements allows the spinning cable to be easily placed on it and thus enables trouble-free work.
  • the storage device used according to the invention thus represents a mechanically stable, easy-to-use device which enables a great reduction in speed and thus allows the rapid spinning of fiber cables with and without take-off godets.
