Definitions
- the invention relates to a drafting system for spinning units according to the preamble of claim 1.
- the fiber material to be spun is usually fed to the spinning units in the form of sliver which are stretched in front of the spinning unit.
- Draw frames are used for this.
- Waste fibers can undesirably wind around the rollers or cylinders of the drafting systems during the spinning operation. If this fiber material adhering to the roller detaches itself from the roller and gets into the sliver track, which is also called the track, the fuse can get unwanted knots or thickenings. This can lead to intolerable defects in the yarn.
- the generic CH 402 690 describes a spinning machine drafting system with a pivotably mounted upper roller support and loading arm that accommodates adjustable holders for the upper rollers.
- Cleaning rollers for the top rollers lie with their own weight on the associated top rollers to be cleaned and remove fiber packages or the like from the top rollers.
- the cleaning rollers are inserted between two upper roller support and load arms in adjacent guides of the cleaning roller holder and each overlap two tracks. With cleaning rollers mounted in this way, the top rollers of the two outer tracks of a spinning machine cannot be loaded with a cleaning roller.
- the first and last spinning units which are fed by the two outer drafting system tracks, are therefore often shut down on spinning machines.
- Such a procedure has the considerable disadvantage that losses in production have to be accepted.
- the device according to CH 402 690 is also not suitable for cleaning the top rollers of the outer track.
- Devices which allow a cleaning roller for one track to be held on only one top roller supporting and loading arm. With such devices, the top rollers of the first and the last track can be cleaned and the production losses mentioned can be avoided.
- EP 0 344 944 AI describes a drafting system in which the upper roller support and loading arms have cleaning rollers arranged opposite one another on each side, which each overlap only one track.
- the cleaning rollers have the shape of a truncated cone. With this form of cleaning roller, the waste fibers released from the sliver are to be taken up and continuously conveyed to a disposal point.
- the conical shape creates a difference in the surface speed between the cleaning roller and the top roller, which should produce a better cleaning effect.
- the fibers picked up by the cleaning roller are acted upon by a force component which moves the fibers towards the smaller diameter of the cleaning roller.
- the cleaning roller is not detachably connected to the holder by rivets, or alternatively screw connections are to be loosened.
- axes running through the upper roller supporting and loading arm, to which two cleaning rollers are attached are a hindrance. Therefore, different constructions of brackets are attached to an upper roller support and loading arm. Handling during the assembly and disassembly of such cleaning rollers is relatively complex, compared to simply inserting the cleaning rollers, as is possible with the CH 402 690 version.
- DE 195 21 265 AI shows a drafting system for a spinning machine, in which a cleaning roller is mounted on a swivel arm, which is arranged on the side of the top roller support and load arm.
- the construction of the bracket is relatively complex.
- the use of cleaning rollers, which are inserted between two upper roller carrying and loading arms and overlap two tracks, is not possible with the device according to DE 195 21 265 AI.
- This is a disadvantage insofar as, with rollers that overlap two tracks, considerably less assembly and disassembly effort is required when cleaning the cleaning rollers on the large number of drafting systems of a spinning machine.
- the design according to the invention there is a holder which allows simple and quick assembly and disassembly. The number of components to be manufactured and assembled is reduced.
- the holder according to the invention is of simple construction and can be used universally both for cleaning rollers mounted between two top roller bearing and loading arms, which span two tracks, and for cleaning rollers for one track each.
- a holding device which is designed as a collar, can be produced particularly easily and inexpensively.
- a link guide which has a spring element on both sides of the bearing element, with which the axis of the cleaning roller can be subjected to a force that presses the cleaning roller against the top roller, ensures that the cleaning roller is always in contact with the top roller and thus leads to one better cleaning effect. At the same time, the game between the link guide and the axis of the cleaning roller is switched off and the direction of the cleaning roller is stabilized.
- FIG. 1 is a perspective simplified partial view of the upper roller bearing and loading arms of a drafting system
- FIG. 2 is a perspective view of a bearing of a cleaning roller for one track and a cleaning roller for two tracks in a bearing element
- FIG. 3 is a perspective view of a mounting of two cleaning rollers for one track each on a bearing element
- Fig. 4 is a perspective simplified partial view of
- Top roller load and load arms of a drafting system with two cleaning rollers each for one track.
- Figure 1 shows an example of a part of a drafting system with two cleaning rollers 1, which are each inserted between two top roller support and loading arms 2, 3 and rest on two top rollers of the front pair of stretching rollers, as well as two further cleaning rollers 4, 5, the side of the Outer top roller support and load arms 2 rest on the top rollers of the outer front stretching roller pairs.
- the cleaning rollers 1 interact with the top rollers of two tracks each, while the cleaning rollers 4, 5 only work with the top rollers a track interact during the spinning operation. All of the drafting roller pairs and their bearings are not shown for reasons of simplification.
- the upper roller carrying and loading arms 2, 3 have bearing elements 6, in which the cleaning rollers 1, 4, 5 are each mounted laterally.
- FIG. 2 Details of the mounting of the cleaning rollers 1, 5 can be found in FIG. 2.
- the upper roller support and load arm 2 and the fastening elements with which the bearing element 6 is fastened to the upper roller support and load arm 2 are not shown in order to be able to show the bearing clearly.
- the bearing element 6 is symmetrical and comprises a guide element 7, 13 on each side, which forms a link guide.
- Each guide element 7, 13 has a spring element 8, 14.
- the cleaning roller 5 is with provided a plaster covering 10.
- the hollow bearing pin 9 has, at its end inserted into the bearing element 6, a collar 12 which grips behind the link guide formed by the guide element 7 and causes the cleaning roller 5 to be held by the bearing element 6 in the case of one-sided storage during operation of the drafting system.
- the spring element 8 is curved so that the hollow bearing pin 9 is subjected to a force which presses the cleaning roller 5 against the force caused by the weight of the cleaning roller 5 against the associated top roller.
- the cleaning roller 5 is removed upwards from the bearing element 6, the spring element 8 is pushed aside by the hollow bearing pin 9 and thereby releases the cleaning roller 5. Even when inserting the cleaning roller 5, the resistance caused by the spring element 8 can be easily overcome.
- the cleaning roller 4 is designed and held in the same way as the cleaning roller 5.
- the guide element 13 with the spring element 14 is designed as a mirror image of the guide element 7.
- the hollow bearing pin 15 of the cleaning roller 1 is inserted into the guide element 13. At the opposite end of the cleaning roller 1, this is inserted with a hollow bearing pin in a bearing element 6, not shown in FIG. 2, of the upper roller supporting and loading arm 3, as can be seen in FIG.
- the cleaning roller 1 lies like the cleaning roller 5 due to its own weight. While the cleaning roller 5 cooperates as a single roller with only one top roller, the cleaning roller 1 cleans two top rollers with its cleaning covering 16.
- the pressing force exerted by the dead weight on the top roller is amplified by the force component which is applied to the hollow bearing pin 15 by the spring element 14.
- a corresponding Force component is applied by the spring element (not visible in FIG. 2) of the bearing element 6 fastened to the upper roller support and loading arm 3.
- the hollow bearing pin 15 of the cleaning roller 1 is replaced by the hollow bearing pin 17 compared to FIG.
- cleaning roller 18 which is only supported on one side is inserted into guide element 13.
- the end of the hollow bearing pin 17 of the cleaning roller 18 is, like at the end of the hollow bearing pin 9, a collar 19 is formed.
- the federal government 19 summarizes the
- Guide element 13 having a link guide and, like the hollow bearing pin 9 of the cleaning roller 5, ensures secure mounting when the cleaning roller 18 is supported on one side. For better clarity of the mounting, the cleaning rollers 5, 18 are not shown in FIG.
- the cleaning rollers 1 mounted on both sides in the arrangement in FIG. 1 are each replaced in the arrangement in FIG. 4 by two cleaning rollers 18 mounted on one side.
- the bearing elements 6 can thus be used universally.
- the upper roller supporting and loading arms 2, 3 can be raised or lowered independently of one another without cleaning rollers having to be removed from the storage.
- cleaning rollers 1 which extend over two tracks, may comprise 15 versions of the hollow bearing pins 9, 17 with collar 12, 19 instead of the hollow bearing pin design. This can further reduce the number of different parts.
- the bearing elements for the cleaning rollers of the rear top rollers maintain the essentially U-shaped design and can be adjusted, for example, in the usual manner by means of elongated holes in the longitudinal direction of the top roller support and loading arm 2, 3.
