Definitions

  • the present invention relates to a device according to the preamble of claims 1 and 4.
  • Thread guide rods made of high-strength plastics are known from DE 33 45 743 A1, but according to this disclosure they do not have completely flat surfaces due to the manufacturing process. This results in difficulties in the axial guidance of the thread guide rod.
  • a disadvantage of such storage is that the thread guide rod, which is moved back and forth at very high speeds and can have a length of more than 30 meters, must also accelerate the mass of the roller guide elements in addition to its own mass. The saving in mass, which is achieved on the one hand through the use of plastics, is canceled out on the other hand by these roller guide elements to be accelerated.
  • a bearing is proposed in DE 3434027 A1 as the bearing for the thread guide rod.
  • bearing elements are arranged on this thread guide rod, which interact with bearing elements arranged on the machine. This has the disadvantage that additional components must be accelerated.
  • Thread guide rods with fibers in the longitudinal direction of the thread guide rod also have the disadvantage that they have the required transverse strength, i.e. do not have sufficient strength with respect to forces in the radial direction on the cross section of the thread guide rod, especially at high traversing speeds and long thread guide rods.
  • the bars must therefore either have a very large cross section or they cannot withstand the extreme loads.
  • the object of the present invention is therefore to provide a thread guide rod which ensures a proper bobbin build-up at high traversing speeds.
  • the thread guide rod according to the invention has carbon fibers which are aligned in the axial direction of the thread guide rod. This orientation of the carbon fibers has the advantage that it creates a high surface uniformity in the axial direction and good bending strength.
  • the structure of the thread guide rod allows an axial sliding bearing.
  • the sheathing of this thread guide rod in the tangential direction increases the transverse strength and the torsional strength to such an extent that it withstands the forces that occur with sufficient certainty.
  • the sheathing is advantageously so thin that the original surface structure of the thread guide rod is largely retained.
  • a carbon fiber fleece has proven to be particularly advantageous for the sheathing of the thread guide rod.
  • the thin fleece with individual shorter carbon fibers binds the preferably continuous carbon fibers arranged in the axial direction in such a way that the thread guide rod has a very high resistance to transverse forces.
  • the thread guide rod is hollow.
  • a round cross-section of the thread guide rod results in the best use of strength with regard to the mass used.
  • the carbon fibers which are aligned in the axial direction, create a continuous drawn profile over the length of the thread guide rod.
  • the thread guide rod is in can advantageously be supported in an axial sliding bearing. No further components are required to support the thread guide rod. In this way, a mass of the thread guide rod is advantageously achieved, which is required only to maintain the required strength.
  • a disadvantage of a carbon fiber reinforced thread guide rod with axially arranged carbon fibers is that it has practically no thermal expansion.
  • the expansion of the textile machine creates an undesirable offset between the textile machine and the thread guide rod, which should be avoided.
  • the device according to the invention achieves the object in that the thread guide rod alternately consists of little heat-expandable material, in particular of carbon fiber-reinforced plastic and of highly heat-expandable material.
  • the thread guide rod in accordance with these sections, consists alternately of carbon fiber-reinforced plastic and of highly heat-expandable material.
  • the individual sections can alternate within a section or section by section.
  • Aluminum has been found to be advantageous as a heat-expandable material.
  • Aluminum has a coefficient of thermal expansion that is several times greater than that of steel. This makes it possible to compensate for the different thermal expansions of carbon fiber reinforced plastic and steel.
  • Aluminum is relatively light, so that it does not significantly reduce the reduction in accelerated masses.
  • Hard anodization (hard coating) of the aluminum results in a good surface hardness for wear-free storage of the thread guide rod.
  • the storage of the thread guide rod directly in an axial plain bearing has proven to be particularly advantageous. In contrast to the prior art, no additional components to be accelerated are required.
  • the surface, in particular the carbon fiber reinforced thread guide rod must be as flat as possible in the axial direction.
  • Polyamide 6 molybdenum sulfide 2 (PA6MOS2) has proven to be a suitable material for the plain bearing. This material allows both low-friction and low-wear storage of the carbon fiber reinforced thread guide rod as well as the thread guide rod made of aluminum.
  • FIG. 2 shows a section of a thread guide rod 1.
  • the thread guide rod 1 is shown partially cut, so that the structure of the individual shells of the thread guide rod 1 is visible.
  • the longitudinal fibers 2 are shown in one part of the section of the thread guide rod 1. These fibers are glued with synthetic resin. They form a constant surface in the longitudinal direction. These longitudinal fibers 2 are surrounded by the nonwoven fabric in the jacket 3.
  • the nonwoven contains undirected short fibers and is preferably very thin. As a result, the mass of the thread guide rod is not significantly increased.
  • the thin fiber fleece causes the surface structure of the body of the thread guide rod with the longitudinal fibers 2 to continue to form essentially the surface of the thread guide rod.
  • FIG. 3 shows an axial sliding bearing for a thread guide rod 1 according to the invention.
  • the axial bearing 4 which is firmly connected to the machine, consists of a support 5 and a cover 6. Support 5 and cover 6 are connected to one another via a screw 7.
  • the two joined parts carrier 5 and cover 6 form a cavity in which the thread guide rod 1 can be changed.
  • the cavity and the thread guide rod 1 have a clearance fit. This reduces the static friction to a minimum and guides the thread guide rod 1 as loosely as is absolutely necessary for the exact laying of the thread on the package.
  • PA6MOS2 has proven to be a particularly advantageous material for the thrust bearing.
  • a textile machine 8 is outlined in section construction.
  • the sections 11 to 18 are arranged between a drive frame 9 and an end frame 10.
  • the thread guide rod 1 is driven in the drive frame 9.
  • the thread guide rod 1 in each third section 13 and 16 is made of the highly heat-expandable aluminum. This division has proven to be an advantageous compromise between reducing the mass and strength of the thread guide rod 1 in connection with the required thermal expansion.
