Description

Yarn guide device

The present invention relates to a yarn guide device for feeding a yarn to a textile machine, in particular a circular knitting machine, having a yarn guide wheel, a drive shaft, and a yarn guide wheel disposed thereon And a carrier having at least one bearing retainer for mounting the drive shaft.

A yarn feeder device of this type is known from EP 1 194 621 B1. The carrier set of the yarn guide device constitutes a two-part housing made of a plastic material. An undivided bearing seat is disposed in each of the housing portions and has a receiving space that is axially opened to one side for use with the rolling bearing. A pressing member made of an elastic body is disposed in an intermediate space between the rolling bearing and the bearing seat.

The two-shell part consisting of a plastic material is complicated in production. Part of the thick wall area is required to simultaneously satisfy the carrier function. Squeeze elements are required to compensate for manufacturing tolerances such as the housing portion produced by the injection molding process.

A yarn guide device having an alternative construction is known from WO 2008/043372. The yarn guide device includes a carrier having an upper and lower leg, and each of the upper and lower legs has a bearing for a drive shaft. An additional housing is placed below the lower leg. The carrier and the housing may be composed of different materials such as metal and plastic materials. The manufacture of a carrier having one of the aligned bearing seats belonging to this type is complicated in production.

The object of the present invention is to develop a yarn guide having an easily produced carrier Device.

This object is achieved by the feature construction of claim 1 of the patent scope.

A yarn guide device according to the invention for feeding a yarn to a textile machine has a yarn guide wheel, a drive shaft, a carrier and at least one bearing holder having at least one undivided Bearing seat and two rolling bearings for mounting the drive shaft. The yarn guide wheel train is disposed on the drive shaft.

The yarn guide wheel train is specially configured to feed a yarn to a knitting machine, preferably a circular knitting machine. In many applications, the yarn guide device can be fastened to a circular knitting machine in such a manner that the drive shaft, i.e. its axis of rotation, runs vertically and thus runs perpendicularly to the axis of rotation of the circular knitting machine.

The carrier is formed from a segment of a strand having a uniform cross section, i.e., an extruded profile. Once extruded, the assembly is one of the components produced in a defined form, such as cast, rolled, drawn or pressed, and has an identical cross-section over its length.

Forming a carrier of a yarn guide device from a segment of an extruded profile allows for the advantageous production of a carrier having a greater number of parts.

Advantageous methods, such as continuous casting or extrusion molding methods, can be obtained for producing an extruded profile. The extruded profile is made in a long length and is capable of producing a large number of segments, and thus carriers, from an extruded profile.

A yarn guide device is in an alternative form having a carrier formed from a segment of an extruded profile. In another alternative, a yarn guide device has a carrier formed from two segments of an extruded profile. In one example, the extruded profiles for the two segments are different, such as U profiles of the sides of different heights. In another example, the two segments used in the carrier are segments of an extruded profile, such as a U-profile, the segments being configured in a mirror-inverted manner to form a carrier.

In one embodiment, the carrier is made of at least one segment of an extruded profile made of a plastic material; in an alternative embodiment, it is formed from a metal. The extruded profile is produced, for example, from a steel, in particular a high grade steel. The carrier therefore has a high strength.

In one embodiment, the carrier is formed from at least one segment of an extruded profile of aluminum. The advantage of producing a carrier from aluminum is that it has good stability with relatively low weight. Also, since aluminum can be formed well, there may be a structure of a carrier that satisfies the requirements.

In one embodiment, the carrier is made from at least one segment of the continuous casting profile, i.e., the extruded profile forming the carrier is created as a continuous casting profile. The carrier can be produced economically by the continuous casting method for the production of the extruded profile of the carrier.

In one embodiment, the carrier is formed from at least one segment of an extruded molding profile, i.e., the extruded profile forming the carrier is first produced as a half finished product, such as a continuous casting profile, and then by squeezing The system produces an extruded molding profile therefrom. During extrusion, the semi-finished product, such as a block, is used to pre-determine the cross-section and thus the contour of the mold to be pressed or stretched.

The extruded molding profile can be produced by direct or indirect extrusion molding from half of the finished product. During direct extrusion molding, a selectively heated semi-finished product is pressed through a die with a die. During indirect extrusion molding, a hollow stamper has a mold on its head that is pressed against a semi-finished product that is selectively heated.

This effect, which is slightly more complicated than continuous casting, allows for a more complex cross-section with an extruded profile, such as a curved outer profile of the extruded profile. The construction of one of the yarn guide devices having an extruded molding profile results in a better quality of the mounting of the drive shaft. For example, a pleasing form of the yarn guide device can also be achieved by bending the outer contour.

In one embodiment, the carrier is formed from at least one segment of an extruded molding profile made of aluminum. As mentioned above, an extruded profile of aluminum gives the carrier lightness and stability and A complex cross section with a large functionality is allowed.

An anodized coating will have the advantage of a higher degree of hardness of the surface of the carrier. For this purpose, the entire segment of the extruded molded profile is anodized as a whole. In an alternative, the machined carrier or segment of the extruded molded profile is anodized. The coating applied to the extruded molding profile by anodization is colorless. In an alternative, the applied coating is colored, such as gold.

In one embodiment, the carrier forms at least one outer wall of a housing of the yarn guide device. One of the carriers formed by a segment of the extruded profile forms up to four of the six outer walls of the yarn guide device, such as a square housing.

Second example

4 to 10 show a yarn guide device 50 according to the present invention of the second example. The yarn guide device 50 of the second example corresponds to the yarn guide device of the first example, except for the differences described below. The corresponding components have the same code.

The carrier 51 of the yarn guide device 50 of the second example is also formed, i.e., like the carrier 5 of the first example, as a segment of an extruded profile, specifically an extruded profile of aluminum. The segmented cross-sectional plane of the extruded molding profile also runs parallel to the drive shaft 4, and the longitudinal direction of the extruded molding profile extends in the direction of the yarn path of the yarn guide device 50.

The carrier 51 forms an outer wall, specifically a cover member D of one of the housings of the yarn guide device 50 and two longitudinal side walls L1 and L2 (Fig. 9). In an alternative, the outer face of the carrier 51 is provided with a coating applied by anodization.

The extruded molding profile and thus the cross-sectional form of the carrier 51 corresponds to the first Example carrier 5. The extruded molding profile of the carrier 51 also has an intermediate cover 52.

In contrast to the first example, the yarn guide device 50 has three housing members 53, 54, 55, the first housing member 53 forming a front lateral side wall, the second housing member 54 forming a base, and a third housing The body member 55 forms a lateral side wall opposite the front lateral side wall, i.e., the housing of the yarn guide device 50 is formed by the housing members 53, 54, 55 and the outer wall of the carrier 51. The housing elements 53, 54, 55 are produced from a plastic material.

The yarn guide device 50 is provided with additional components (Fig. 6).
