Description

[Technical field]

[0001] The present invention relates to a textile machine component, in particular a spindle structure with a spindle and a bearing housing, and to a method for providing component information in a textile machine component, in particular a spindle structure with a spindle and a bearing housing for a spinning or twisting machine.

[0002] The identification of textile machine components by component information, for example in the form of serial numbers or batch numbers, is already well known. Through the serial numbers, information stored in a corresponding data base can be called up for the respective textile machine component, such as further component information, for example the place of manufacture, the time of manufacture, the material source, the material composition and / or the material properties of the component. Access to such information makes it possible to determine possible causes arising from the production process of the textile machine component, for example in the case of unforeseen defects or in the case of higher than expected wear leading to a shorter than expected service life. Besides the arrangement of the serial number and / or batch number as component information, which provides specific information about the component only indirectly, i.e. with the aid of a corresponding data base, other information, such as, for example, the manufacturer, the intended use or the maintenance cycle, can also be directly applied to the textile machine component, which allows the observer to recognize such information directly, i.e. without the aid of a data base. The component information can then be indicated on the textile machine component, for example by a corresponding engraving or printing, for example on the outer surface of the bearing housing of the spindle structure.

[0003] Environmental factors in the context of storage of the textile machine component as well as mechanical factors during operation of the textile machine component can lead to the component information becoming unreadable to the operator, whereby the indecipherability can also result from corrosion or wear of the textile machine component, the effects of corrosion being able to act on it already during storage of the textile machine component.

[0004] In order to protect components that are subjected to load, it is already known to provide them with shrinkable plastic coverings that come into contact with the surface of the component within the context of a heat shrinking process. Although the use of shrink-applied plastic coverings, as is known for example from WO 96 / 19334, which discloses the basic use of shrinkable sleeves, films, hoses, etc., for example for the application to cables, pipes, etc., to provide a heat- and chemical-resistant covering, does provide protection for the machine component against external factors that have a corrosive effect on the surface, the covering also means that the operator is unable to detect the component information displayed on the machine component.

[0005] Against this background, it is an object of the present invention to provide a method for ensuring the provision of permanent and reliable component information in a plastic-encased textile machine component, in particular in a spindle structure for a spinning or twisting machine.It is also an object of the present invention to provide a plastic-encased textile machine component, in particular a spindle structure, which has a reliably detectable component information.

[0006] The present invention solves these problems by a method having the features of claim 1 as well as by a device having the features of claim 7. Preferred developments of the method according to the invention are set out in the dependent claims 2 to 6. Embodiments of the textile machine component according to the invention are set out in claims 8 to 12 which refer back to claim 7.

[0007] The method according to the invention enables the reliable provision of component information, which includes product-specific information, such as the material source of partial or complete textile machine components, their material composition and / or material properties, production process of the textile machine components or individual component parts, production data such as place of origin, production period, manufacturer, as well as operational data, service life, maintenance cycles, etc., which are important in particular for further processing / treatment processes or for the utilization of the components. The component information can here be in the form of character strings, for example numbers, letters or compound symbols, or in the form of a coding, for example a barcode or in the form of an RFID chip or a magnetic element.

[0008] Providing component information on a textile machine component is understood in the context of the present application to mean an arrangement of component information that can be detected, in particular readable, by an operator in a reliable manner, i.e. for example also after the influence of disturbing factors. For this purpose, it is provided according to the invention that the textile machine component, in particular the bearing housing of the spindle structure, is at least locally covered with a heat-shrinkable plastic covering providing the component information, which is shrink-fitted to the textile machine component, in particular to the outer surface of the bearing housing. According to the invention, the plastic covering is then designed to allow detection of the component information, while simultaneously protecting the textile machine component against external factors, in particular corrosive factors, by the plastic covering itself carrying the component information and / or being designed to allow detection of the component information arranged on the textile machine component in the shrink-fitted state. Preferably, detection can then be performed by the operator and / or by a detection unit.

[0009] Thus, by using a shrink-fitted plastic covering, the method of the invention makes it possible to provide a textile machine component, in particular a spindle structure of a spinning or twisting machine, that is reliably protected against external factors, in particular corrosive factors. At the same time, the suitability of the plastic covering for providing component information provides for reliable detection of operation-relevant data, such as, for example, the operating conditions of the corresponding textile machine component, in particular the spindle structure, which are to be noted for the subsequent use of the textile machine component, in particular the spindle structure. In this way, the plastic covering not only serves to protect the surface of the textile machine component, but also to reliably provide component information for the operator.

[0010] To this end, in a particularly preferred embodiment of the invention, it is intended that the component information is arranged on a textile machine component, in particular on the outer surface of a bearing housing, and then a plastic covering is shrink-fitted to cover the component information, the plastic covering being configured and shrink-fitted in such a way that external, in particular sensor-based or visual, detection of the component information can be carried out by a detection unit and / or an operator.

[0011] In this embodiment of the invention, the plastic covering covers the component information arranged on the textile machine component, in particular on the outer surface of the bearing housing of the spindle structure, in such a way that it can be subsequently detected, in particular visually readable. The method according to this development of the invention allows the component information to be directly arranged on the textile machine component within the framework of the manufacturing process. By using a suitable plastic covering which allows the component information to be detected from the outside, in particular visually, in the shrink-fitted state, further steps for identifying the component information on the textile machine component can be omitted. In this way, the component information can be provided in a particularly simple and cost-effective manner overall, using a plastic covering which can be shrink-fitted on the textile machine component.

[0012] Particularly advantageously, it is provided here that a plastic covering which is transparent in the region of the component information in the shrunk-in state is shrunk-in on the textile machine component, in particular on the outer surface of the bearing housing. The use of a plastic covering of this kind allows an operator or a detection unit to detect, i.e. read out or read out, the component information arranged on the textile machine component in a particularly simple manner, the component information being reliably protected by the plastic covering against, in particular, corrosive factors which would destroy the component information. In particular, the use of a plastic covering which is transparent or at least partially transparent at least in the region of the component information in the shrunk-in state ensures a particularly simple and rapid detection of the component information. Furthermore, preferably, the partially transparent region of the plastic covering can be embodied in a color. Alternatively or additionally, the plastic covering can be embodied in a color outside the transparent or partially transparent region, further preferably in a color which is the same or different from the partially transparent region. For example, components for different applications can be identified by color and can therefore be easily distinguished from one another. In particular, such a method of distinction is preferred for components of similar or identical shape.

[0013] As a complement or alternative to disposing the component information on the textile machine component, another embodiment of the invention contemplates disposing the component information on a plastic coating, particularly on the outer surface of the plastic.

[0014] The application of the component information on the plastic covering makes it possible to dispense with complex methods for indicating the component information on the textile machine component, for example by marking. The component information can be indicated on the plastic covering in a simple manner before or after the plastic covering is shrunk onto the textile machine component. The application of the component information on the plastic covering also makes it possible to use non-transparent, in particular colored, plastic coverings, so that the plastic covering itself can be used for identification purposes, in particular for the distinction of the textile machine component, or also for marketing purposes. The indication of the component information on the plastic covering can then be effected, for example, by means of low-cost printing methods, with durable printing methods being preferably applied. For example, by applying a printing color, preferably assigned to each one of the component types, different component types can be visually identified and distinguished from one another in a simple manner.

[0015] Furthermore, in a particularly preferred embodiment of the invention, it is provided that the component information is indicated in machine-readable form on the textile machine component, in particular on the outer surface of the bearing housing and / or on the plastic coating. In this embodiment of the invention, the component information is not provided in the form of plain text, but in coded form, for example in the form of a bar code, a QR code, a readable RFID chip or a magnetically coded means, which can be read by a suitable reader, and on the basis of the coding the corresponding component information is provided, in particular in plain text, or provided to a control unit. The use of machine-readable codes allows a particularly simple and space-saving arrangement of the component information on the textile machine component. The component information can here be indicated or printed directly on the textile machine component and / or on the plastic coating or can be arranged, for example, on a label which is applied to the textile machine component or to the plastic coating.

[0016] The attachment of the plastic coating to the textile machine component is carried out in a known manner with suitable equipment, in such a way that the plastic coating is first placed on the textile machine component, or at least on one area of ​​the textile machine component, and then the plastic coating is heated in a defined manner by a suitable heat treatment, whereby the plastic coating shrinks and is thereby shrink-fitted to the textile machine component, so that it then abuts against the surface of the textile machine component.

[0017] In a preferred development of the method according to the invention it is provided that the plastic sheath is hose-shaped and / or that the textile machine component is heated in the bonding area with the plastic sheath prior to shrink-fitting.

[0018] The hose-like embodiment of the plastic covering allows a particularly easy placement on the textile machine component, where the plastic covering is applied to the textile machine component prior to the heat treatment. The plastic covering is then shrink-bonded to the textile machine component by suitable thermal action. The hose-like configuration hereby ensures a particularly uniform placement of the plastic covering in the shrink-fitted state. Pre-heating of the textile machine component, at least in the bonding area with the plastic covering, ensures a particularly good bond of the plastic covering to the textile machine component.

[0019] A feature of the textile machine component according to the invention, in particular a spindle structure having a spindle and a bearing housing for a spinning or twisting machine, is that a plastic coating providing component information is shrink-fitted to at least one area of ​​the textile machine component, in particular to at least one area of ​​the outer surface of the bearing housing.

[0020] The textile machine component according to the invention is characterized in that in the area where the textile machine component is connected to the plastic covering, it is reliably protected by the plastic covering against external factors, in particular corrosive factors, which could lead to damage to the surface of the textile machine component and to the destruction of the component information arranged thereon. At the same time, an embodiment of the plastic covering configured for providing the component information ensures reliable detection of the component information by an operator even after the impact of a damaging factor on the textile machine component. In this case, according to the invention, the plastic covering is configured for providing the component information, for which purpose the plastic covering itself is provided with the component information and / or is configured for the provision of the component information arranged on the textile machine component, i.e. for detection by an operator.

[0021] In a particularly preferred embodiment of the invention, in the case where the component information is arranged on a textile machine component, in particular on the outer surface of a bearing housing of a spindle structure, the shrink-fitted plastic covering is designed in such a way as to enable an external, in particular visual, detection of the component information by an operator, and is particularly advantageously designed for this purpose to be transparent in the shrink-fitted state, at least in the region of the component information, so that the component information can be read out particularly easily by the operator.

[0022] Alternatively or additionally, in another embodiment of the invention, it is provided that component information is arranged on the shrink-fitted plastic sheath, in particular on the outer surface of the plastic sheath. In this embodiment of the invention, the plastic sheath has component information embedded therein, in particular arranged on the outer surface of the plastic sheath, which is particularly preferably printed or glued onto the plastic sheath and is there easily detectable by an operator or a detection unit. The use of the plastic sheath as a carrier of component information makes it possible to provide this in a particularly simple manner, in particular in a visual manner or in a machine-readable and easily detectable manner, for example by the component information standing out in high contrast with the coloring selected for the plastic sheath by means of a suitable printing color. The coloring of the plastic sheath can then be used for identification purposes and / or for the differentiation of the textile machine components and / or for marketing purposes.

[0023] Furthermore, in a particularly preferred embodiment of the invention, it is intended that the component information is machine-readable. For machine readability, the component information is provided, for example, in the form of a bar code or QR code or by means of an RFID chip or magnetic coding means, which component information is detected by a suitable reader and displayed thereon and / or transmitted via the reader to a corresponding processing unit, such as a control unit, an evaluation unit and / or a display unit. The use of machine-readable codes makes it possible to provide a particularly wide variety of component information in a readable manner in a limited design space of a textile machine component.

[0024] The embodiment of the plastic covering for placement on the textile machine component can in principle be freely selected. In one particularly preferred embodiment, however, the plastic covering is configured in the form of a hose. This embodiment of the invention ensures a particularly simple and cost-effective placement on the textile machine component, in particular on the cylindrical bearing housing of the spindle structure. Furthermore, the use of a hose-shaped plastic covering ensures that after the heat treatment in which the plastic covering is shrink-fitted onto the surface of the textile machine component, the plastic covering is evenly positioned on the surface of the textile machine component, in particular on the surface of the bearing housing. [Brief description of the drawings]

[0025] An embodiment of the present invention will now be described with reference to the drawings in which:

[0027] As an example of a textile machine component, a spindle structure 1 for a spinning or twisting machine is shown in a perspective view in Fig. 1. The spindle structure 1 has a bearing housing 6 which serves to position the spindle structure 1 on a spindle rail of a spinning or twisting machine (not shown here) and to rotatably support a spindle 3 on which a reel can be fitted during operation of the spinning or twisting machine.

[0028] The bearing housing 6 has a coaxially arranged, hose-shaped plastic sheath 2 on its outer surface, which is shrink-fitted onto the bearing housing 6 due to its coaxial arrangement, so that the textile machine component together with the plastic sheath 2 arranged on it is subjected to an adapted heat treatment. On the outer surface 5 of the plastic sheath 2, a first component information 4 in the form of the name of the manufacturer and a second component information 7 in the form of a QR code are printed, which contains product-specific information of the textile machine component, such as the material source, the material composition, the material properties, the manufacturing process of the individual component areas, production data, such as place of origin, production period as well as operating data, service life, maintenance cycles, etc. The printing here is carried out by a suitable printing device subsequent to the heat treatment.
