Definitions
- the invention first relates to a method for depositing running filament or fiber cables, in which the goods, which are preferably delivered at high speed, are fed from a delivery device, then decelerated with respect to its straight-line movement by moving into a winding position by means of two at a distance parallel to each other, shifted away from each other, but still partially overlapping wheels, on the sides of which axially aligned pins are fastened overlapping one another as deflection members, is deflected into a zigzag position, then the turns are then immediately released again by the deflection members and thus be fed to a storage device in free fall according to the loop speed.
- DE-A-2 261 366 discloses a method according to which the speed of the fiber cable is reduced by braking the fiber cable with respect to its rectilinear movement in such a way that it can be safely placed in a can.
- the cable is fed into moving conveyors, the speed of which is lower than the cable speed.
- a device is then known which consists of two cooperating conveyor rollers which can be moved in the opposite direction of rotation and in which essentially radial webs are arranged on the lateral surface at the same distance.
- the fiber cable meets the fiber cable stacked in the conveying member in the direction of its axis, where it is forced by compression to form folds which are arbitrary. Therefore it is impossible to avoid splaying of the fiber cable and confusion in the cable.
- the object of the invention is to develop an additional method for storing goods, with which any changes in the cable cohesion, in particular also in the goods already stored, are avoided.
- the device for carrying out the method is to be improved overall, not only to be supplemented, in order to obtain a device which is always functional, easy to operate and in particular easily accessible in practice.
- the invention provides, in order to achieve the object, that the material, placed in uniform zigzag turns, be shifted closer to each other at least once before final storage.
- the purpose of this is not to increase the number of folds in order to reduce the depositing speed, but rather only to fold the folds closer together, which automatically results in a low falling speed of the cable into the can.
- the deflection elements exert a not too great longitudinal tension on the cable when the folds are formed. It is therefore advantageous to guide the cable between the delivery device and the fold-forming member by means of additional conveyance. This causes the product to be fed into the wrinkling organ with little tension.
- the device for carrying out the method consists first of all of the pair of wheels known from EP-A-9 162 with two spaced-apart parallel, mutually displaced, but still partially overlapping wheels, on the sides of which axially aligned pins as Deflection devices for the material to be laid in turns are attached to one another. If, by means of this device, approximately horizontally extending folds are fed to the can, it is advantageous if the turns come to rest close to one another. It is therefore envisaged to arrange an organ that adjoins this winding formation element in front of the depositing device and that accommodates the windings in their laid width as the upsetting device that places the windings closer together. A chute, a driven revolving transport roller or an endless belt would be conceivable as the upsetting device.
- the transport roller with its horizontally aligned axis should be arranged vertically below the windings flying towards the roller.
- the fold that has just been deposited is then removed from the point of impact by the rotation of the transport roller and is thus conveyed in the direction of the can. So the successive turns cannot collide.
- the upsetting device Since the windings strike the upsetting device at a certain speed, it can be advantageous to support the release of the turns from the upsetting device. It is therefore expedient to assign a stripper to the upsetting device, in particular the conveyor device. For this purpose it is advisable to provide the transport roller with circumferentially parallel grooves in which a finger-shaped cable wiper engages. In this way, the capillaries lying directly on the roller are reliably detected by the stripper.
- the transport roller can be designed as a suction drum under suction.
- the conveying device can oscillate in order to influence an even filling of the can.
- the device according to EP-A-9162 consists of two wheels, the deflection pins being attached to the spokes of these wheels.
- the pinwheels can be mounted on two intermeshing gearwheels, one of which is driven by a controllable motor. If the wheels are equipped with different perforated rings, the engagement and loop length can be changed by reassembling the pins according to the radii and divisions of the perforated rings.
- the pair of wheels with an additional conveying device, e.g. pre-arrange an injector nozzle, a pair of reel sprockets, pins or gears; because it would not be a good thing if the pair of pinwheels had to build up a substantial tension to the pull-off unit.
- an injector nozzle With the interposition of an injector nozzle, it is also possible to maintain the pull-off voltage from the pull-off required to avoid winding. At the same time, the tension between the nozzles and the pin wheels is set as low as desired. The otherwise damaging effect of the injector nozzle, which can destroy the cohesion of the cable, is ineffective here, since the cable is brought back together in an orderly manner on the pair of pin wheels.
- Inserting the cable is particularly easy if the pins of one pin wheel, e.g. 10-15 mm longer than that of the other pin wheel. You can then guide the cable picked up with a suction nozzle all the way around the pin wheel without the cable coming into contact with pins of the other wheel. If you then move a thread guide attached shortly before the pin wheel into an end position (thread guide approximately in the middle of the interlocking pins), the cable automatically threads itself.
- this can be achieved by using e.g. an injector nozzle or a small pair of pinwheels or gearwheels with a relatively small number of pins or teeth and a small loop length is switched on, which supplies the necessary pull-off voltage for pre-pulling.
- the small pair of pinwheels must then rotate at about the spinning speed in order to achieve the required tension for pulling off.
- the cable is then routed loosely or in a free-hanging loop of a thread brake, which ensures a low pre-tension of the cable entering the pair of storage pinwheels.
- the spinning cable 1 coming from the spinning machine is fed to the driven rotating pin wheels 3 and 4 via the pull-off 2.
- the pin wheels consist of two axially parallel disks or wheels, which have the same number of axially parallel pins a "a2 .... b" b 2 ... arranged around their circumference.
- the pin wheels 3 and 4 are arranged so that the wreaths formed by the pins face each other and interlock.
- the pins are arranged such that, for example, a pin b of the wheel 4 is in the gap between the pins a and a 2 of the wheel 3.
- the cable can be easily threaded to operate the device.
- the cable 1 When brought into contact with the pins running towards one another, the cable 1 automatically zigzags around the pins, each time outside around the pins, as seen from the associated wheel axle. If the cable 1 has passed the middle of the engagement of the pin wheels, it no longer has any folding forces acting on it. Under the influence of the centrifugal force, the cable detaches from the pins while maintaining the loop shape and leaves the pair of pin wheels in this loop shape. Loop angle and loop length are determined by the engagement of the pin wheels. In any case, this should be more than 10 mm. With these pin wheels, interventions of 50 mm and more can be easily adjusted with the correspondingly large loop lengths, without there being a risk of pinching the cable.
- the folded cable leaving the pin wheels 3 and 4 falls onto a rotating roller 5, which is arranged exactly below the falling cable turns and whose axis is perpendicular to the axes of the pin wheels.
- the sudden braking of the folds onto the roller 5 does not damage the fiber cable, since the impact occurs perpendicular to the longitudinal direction of the individual capillaries of the fiber cable.
- the pleats are simultaneously laid, so that the individual capillaries of a loop lie on one another at the final laying angle after being folded. This prevents confusion of the cable and an inadmissible shifting of the cable that has already been deposited.
- the folded cable now leaves the roller under the action of centrifugal force and gravity, preferably with the help of an additional scraper 6, and falls at a normal rate of fall, possibly in a slight arc, into the storage can 7 below.
- the loop speed Vs after leaving the pin wheels depends on the delivery speed. B. from the spinning speed v a , the number of pins and the engagement of the pin wheels. For example, if the pin wheel diameter is 25.2 cm, each wheel has 24 pins with a diameter of 10 mm and if the engagement is 15.3 cm, it is quick speed of the loops in relation to the delivery speed vs .: 0.17 v a .
- the cable 1 can be fed to the pinwheel pair as desired. It can be done by placing the cable around the pins of one wheel as shown. There is then a relative movement between the pins and the cable. The cable will slide on it, but this is of no significant importance. However, it may be expedient to immediately arrange an additional conveying device, such as an injector nozzle, to the pair of wheels 3, 4 in order to favorably influence the low-tension feed of the cable into the pair of wheels 3, 4.
- the conveyor can also be arranged so that the cable is inserted immediately between the interlocking pins. Using an injector nozzle as a conveying device is possible without disadvantage since any inflation of the cable in the pair of pinwheels is reversed.
- the roller 5 is advantageously designed as a grooved roller (FIG. 1) into which the finger-shaped wiper 6 engages. This means that individual capillaries adhering to the roller surface can be lifted off the roller surface undamaged since they are perpendicular to the wiper in accordance with the loop direction. A rotating belt with a scraper or a suction drum under suction can also take the place of the roller.
- an additional traversing of the loop cable can be advantageous. It can be achieved very simply by setting the roller 5 in a periodic, reciprocating rotary movement about an axis perpendicular to the roller axis (FIG. 5).
- the loop cable leaves the roller in the direction of the centrifugal force, the direction of which is continuously changed by the rotation, so that the cable oscillates.
- the tape folding described by pin wheels has the decisive advantage over a gear rack that pinch points in the cable can no longer occur.
- the adjustment of the wheels to certain loop lengths is not critical. It is done by adjusting the engagement of the two pin rings. With the engagement of the two pin wheels and their peripheral speed, the tension of the running cable between the pin wheels and the pull-off can be adjusted.
- the pens z. B consist of commercially available ceramic tubes with a metal core.
- FIG. 1 an intermediate deduction is provided compared to the illustration in FIG. 1.
- the cable 1 runs to the intermediate take-off 8, such as an injector nozzle or gear pair, is taken up after the intermediate take-off with the threading suction nozzle, not shown, and via thread guide rollers 9 and 10 by a thread brake 11 and the guide guide 12 in the initial position around the pin wheel 4 out to below the rotating pinwheel pair (see Fig. 7).
- the guide guide 12 is brought into the end position according to the arrow in FIG. 7.
- the cable 1 thus threads itself into the pinwheel pair 3, 4, and the suction nozzle can be switched off. Now the speed of the pinwheel pair 3, 4 is reduced to such an extent that between 12 and 10 there is no longer any significant cable tension.
- the thread guide roller 10 is then removed from the thread run and the speed of the pinwheel pair 3, 4 finely regulated so that a free cable loop 13, which can be set to any length, hangs between the intermediate take-off 8 and the thread brake 11.
- the length of the loop 13 can by z. B. a button 14 or be determined by an optical control device. This control element then has to bring the pulling-off speed of the pinwheel pair 3, 4 into the desired target state.
- the thread brake 11 can be replaced by making the thread guide roller 9 variable in length. It is expedient to make them movable according to arrow 16 with a maximum deflection. Furthermore, a slight preload of the cable in front of the pin wheel 3, 4 ensures a weight or spring loading of the roller 9, which after removal me the thread guide roller 10 is effective from the cable run.
- the wheel 4 has longer pins than the wheel 3. This results in an area on the pins b of the wheel 4 on which the cable 1 to be threaded can be placed without touching the pins a of the wheel 3. After the cable 1 has been moved with the guide 12 into the grooves 15 shown enlarged in FIG. 8, the cable is threaded into the pin wheels 3, 4 in a functional manner.
