Cleaning brush for cleaning clothing in a textile machine

Abstract

A cleaning element to be fastened on a cylindrical basic body has a longitudinal axis and is designed as a cylindrical hollow element and comprises a skeleton and a spiked lattice stretched on the skeleton. The skeleton is connected to the spiked lattice by means of a rubber sealing compound, and an inner surface of the cleaning element facing the longitudinal axis is formed by the skeleton or the rubber sealing compound. The skeleton is formed by support rings which are arranged at certain intervals concentric with the longitudinal axis and which are held by means of one or more webs extending in the direction of the longitudinal axis.

DETAILED DESCRIPTION

(7) Reference will now be made to embodiments of the invention, one or more examples of which are shown in the drawings. Each embodiment is provided by way of explanation of the invention, and not as a limitation of the invention. For example features illustrated or described as part of one embodiment can be combined with another embodiment to yield still another embodiment. It is intended that the present invention include these and other modifications and variations to the embodiments described herein.

(8) FIG. 1 and FIG. 2 show a schematic illustration of a first embodiment of a cleaning element 1, wherein FIG. 1 shows the cross-section and FIG. 2 shows the longitudinal section at the point A-A according to FIG. 1. The two figures are considered together in the following. The cleaning element 1, with its longitudinal axis 4, is held on a cylindrical basic body 2 and comprises a skeleton 3 having a spiked lattice 5 on the outside. The skeleton 3 is composed of support rings 8 which are arranged concentric with the longitudinal axis 4 and are held on webs 9 extending in the direction of the longitudinal axis 4. The webs 9, in turn, are mounted on a tube 10. The tube 10 is cylindrical and has a surface 7 facing the basic body 2. The cleaning element 1 is supported on the basic body 2 via this surface 7. The condition of the surface 7 can be designed to be smooth or structured. A spiked lattice 5 is applied over the concentrically positioned support rings 8. The spiked lattice 5 has wire hooks 12 which are inserted therein and are distributed over the surface. The wire hooks 12 are schematically illustrated in the figures and can have various sizes, shapes, and lengths.

(9) The space between the spiked lattice 5 and the tube 10 of the skeleton 3 is filled with a rubber sealing compound 6. This produces a connection between the skeleton 3 and the spiked lattice 5. The spiked lattice 5 is thereby given a stable cylindrical shape and can be slid over the skeleton 3 on the basic body 2.

(10) The extension of the cleaning element 1 in the direction of the longitudinal axis 4 does not correspond, in every case, to the length of the basic body 2 to be provided with the cleaning elements 1. The skeleton 3, i.e., the tube 10 of the skeleton 3 in the embodiment shown, is formed so as to have teeth 11 at the ends thereof. If two cleaning elements 1 are then slid onto the basic body 2, the teeth 11 engage into one another and the two cleaning elements 1 are coupled to one another in a rotationally locked manner. The same tooth system 11 can be used on at least one end of the basic body 2 in order to hold the cleaning elements 1 on the basic body 2 in a rotationally locked manner (not illustrated).

(11) FIG. 3 shows a schematic illustration of a longitudinal section of another embodiment of a cleaning element 1. The cleaning element 1 has been slid onto a basic body 2. In the embodiment shown, the cleaning element 1 comprises a skeleton 3 which is composed of a plurality of components 14, 15. Two identical skeleton elements 14, which are connected by means of an intermediate element 15, are illustrated. Each of the skeleton elements 14 has a tube 10 and support rings 8 arranged concentric with the longitudinal axis 4, each of which said support rings is held by a web 9. The intermediate element 15 is used only to couple the skeleton elements 14 and does not have support rings 8 or webs 9. The intermediate element 15 creates a rotationally locked coupling of the skeleton elements 14 by means of a tooth system 11 provided at the ends of the skeleton elements 14. By using various lengths of the intermediate element 15, it is possible to provide the cleaning elements in any length while using standardized skeleton elements 14. A spiked lattice 5 having wire hooks 12 inserted therein is applied over the entire skeleton 3 or the support rings 8 thereof. The space between the tube 10 and the spiked lattice 5 is filled with a rubber sealing compound 6.

(12) FIG. 4 shows a schematic illustration of a cross-section of another embodiment of a cleaning element 1. The cleaning element 1 comprises a skeleton and a spiked lattice 5, which has wire hooks 12 inserted therein, applied over the skeleton. The skeleton is composed of concentrically arranged support rings 8 which are held by webs 9. The rubber sealing compound 6 connecting the skeleton and the spiked lattice 5 is introduced such that, in turn, a hollow element results, which has an inner surface having a structure or shape matched to a basic body 2. The embodiment of two raised areas 13 in the cleaning element 1 is shown in FIG. 4 as an example. In the state of use, these raised areas 13 engage into corresponding recesses of the basic body 2 and thereby result in a positive-locking and, therefore, rotationally locked connection between the cleaning element 1 and a basic body 2. The basic body 2 can be designed as a multiple-splined shaft, for example.

(13) FIG. 5 shows a schematic illustration of the design of a cleaning brush. A plurality of cleaning elements 1 are held on a shaft 2. In this connection, a first cleaning element 1 is slid onto the shaft 2 and is held in a clamping element 18. The clamping element 18 is designed such that the cleaning element 1 is held in a rotationally locked manner. A coupling piece 16 is installed on the shaft 2 before a second cleaning element 1 is slid on. The coupling piece 16 is rotationally connected to the cleaning element 1 by means of a tooth system provided therein. Instead of a tooth system, other connections, such as pins, which result in a rotationally locked connection of the cleaning element 1 and the coupling piece 16 are also conceivable. A second cleaning element 1 is then slid onto the shaft 2 against the first cleaning element 1 in the direction of the longitudinal axis 4 and in the arrow direction 17. The second cleaning element 1 also engages into the coupling piece 16, by means of a corresponding design of the cleaning element 1. This results in a rotationally locked connection of the two cleaning elements 1 via the inserted coupling piece 16. The coupling piece 16 is completely accommodated by the two cleaning elements 1 such that, in the fully assembled state, the cleaning elements 1 rest against one another without an intermediate space therebetween.

(14) Modifications and variations can be made to the embodiments illustrated or described herein without departing from the scope and spirit of the invention as set forth in the appended claims.
