Definitions
- the invention relates to a drafting system for a knitting machine for
- Output roller pair each having a pressure roller and an electric motor driven drive roller and the rollers and the
- Electric motors are arranged on the front side of a base plate, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers.
- Such drafting systems are already in WO 2009/026734 AI
- the present invention is therefore based on the object
- the object is achieved by a drafting system for a knitting machine for producing a fiber structure from a roving with about
- Output roller pair each a pressure roller and an electric motor having controlled drive roller and the rollers and the electric motors are arranged on the front side of a base plate, while the motor shafts are passed through the base plate and are connected via drive means with the mounted in the base plate axes of the drive rollers, which is characterized in that on the back of the Base plate is provided a clamping device with which the pressure rollers of the Riemchenwalzencrues and the
- Output roller pair can be pressed against the drive rollers.
- the tensioning device with which the pressure rollers against the driven rollers are pressed to allow the stretching of the fiber structure, is also known in the drafting on the
- Pressure rollers must be acted upon by the clamping device, this has a relatively large number of components which, when arranged on the front of the drafting, d. H. on the side on which the fiber strand passes through, are exposed to fiber fly and thus pollute. You need to
- Clamping device arranged on the drafting system rear, where they can not be contaminated by fiber fly and not block the free access to the pairs of rollers and straps on the front.
- the axes of the pressure rollers are guided with clearance through openings in the base plate and from the clamping device in the openings movable up and down. If the tensioning device is relaxed, the rollers can be manually moved within the scope of the clearance permitted by the openings
- Rear side of the base plate are rotatably mounted in slides, wherein the slide can be acted upon by the tensioning device with a spring force.
- the slides which may be mounted in guides, allow a precise movement of the pressure roller axes by the of
- Clamping device generated spring force, which can be generated by each of the slider associated springs.
- the clamping device has a bar extending over the slider, slidably arranged on the base plate bar, with which the contact pressure can be generated. By simply moving this bar can thereby press the pressure rollers against the drive rollers or relieve. The strip can be moved longitudinally to the
- Base plate arranged and provided with cams, wherein the cams of the strip on the cooperating with the sliders springs
- springs can preferably be used thigh springs. These can be arranged in an adjustable spring block, so that by moving the spring block, the spring generated by the springs
- mechanical clamping device also have a pneumatic, hydraulic or electrical clamping device.
- the tensioning device can be activated and deactivated in a manner known per se by a pivoting lever connected to the tensioning device.
- the pivot lever can be arranged easily accessible outside of the housing of the plate.
- the drafting system can be designed differently. Relatively often so-called 3-roll drafting systems are used, d. H. the drafting system may have, in addition to the Riemchenwalzen and the output roller pair an input roller pair, the pressure roller is also acted upon by the clamping device.
- Outgoing pair of rollers may be arranged a suction, with the help of which fibers and dust can be sucked off before moving on
- the invention also relates to a knitting machine, preferably a circular knitting machine, which is equipped with at least one drafting device according to the invention.
- a knitting machine preferably a circular knitting machine
- at least one drafting device according to the invention is equipped with at least one drafting device according to the invention.
- 1 is a perspective view of the front of a
- Fig. 2 is a view of the rear of the drafting system of Fig. 1;
- FIG. 3 shows a detailed view of the rear side of the drafting system from FIG. 1 with active tensioning device
- Fig. 4 is a view corresponding to FIG. 3 with inactive
- Fig. 5 is an enlarged detail view of the rear of the drafting system of Fig. 1;
- FIG. 6 is an enlarged detail view of the axle bushings through the base plate of the drafting system from FIG. 1.
- the drafting system 10 of FIG. 1 has a base plate 11, on the front side 12, two motors 13, 14, an input roller pair 15, a Riemchenwalzencru 16 and a pair of output rollers 17 are arranged.
- Each of the roller pairs 15, 16, 17 consists of a lower driven roller 15.1, 16.1, 17.1 and an upper one
- the motors 13, 14 are protected from fiber fly by a cover omitted in FIG.
- On the output roller pair 17 is also a
- Fig. 2 shows the back 18 of the base plate 11, on which an electronic control part 19 and a mechanical part 20 of the drafting system 10th
- the shaft 14.1 drives via a toothed belt 22 and a plurality of pinion shafts 16.3, 15.3 of the belt drive roller 16.1 and the input drive roller 15.1.
- Bar 30 was moved in the direction of the arrow to the outside.
- the cams 32 are thereby no longer in contact with the Schenkeifedern 27, 28, 29.
- the sliders 33, 34, 35 are not further pressed down.
- axles 15.4, 16.4, 17.4 of the pressure rollers 15.2, 16.2, 17.2 are respectively mounted in the slides 33, 34, 35. These axes 15.4, 16.4 and 17.4 are by
- the tensioning device 25 If, however, the tensioning device 25 is inactive (FIG. 4), the upper pressure rollers 15.2, 16.2, 17.2 can be moved upwards by hand, as far as the play between the axles 15.4, 16.4, 17.4 and the openings 36 permits.
