DETAILED DESCRIPTION

[0042] All of the figures show an apparatus, denoted in its entirety by 1, for producing bristle products 2. Examples of bristle products 2 which can be produced by means of the apparatus 1 shown in the figures are brushes, brooms and paintbrushes.

[0043] The apparatus 1 comprises two tufting units 3 and 4 with which bristle bundles 5 can be tufted into provided bristle product bodies 6. Owing to the fact that the apparatus 1 has a total of two tufting units 3 and 4, the apparatus 1 is configured redundantly with respect to the tufting of bristle bundles 5.

[0044] The tufting units 3 and 4 can be moved optionally and alternately from a setting-up position 7 outside a working chamber 8 of the apparatus 1 into a working position 9 within the working chamber 8. In this way, one of the two tufting units 3 or 4 in the working position 9 can always be arranged within the working chamber 8 while measures for servicing, checking, maintenance, repair, conversion and/or setting up can be undertaken at the respective other tufting unit 4 or 3, which is located in the setting-up position 7.

[0045] The apparatus 1 shown in the figures has advantages in particular for a change of pattern, for which frequently more extensive work has to be undertaken at a tufting unit. While the one tufting unit 3 or 4 which is located in the working position 9 can continue to be operated, it is possible to undertake corresponding measures for adapting the apparatus 1 for changing the pattern at the other tufting unit 4 or 3, which is located in the setting-up position 7 outside the working chamber 8.

[0046] The apparatus 1 can therefore be used without relatively great interruptions during the production of bristle products 2. The two tufting units 3 and 4 therefore promote high overall equipment effectiveness (OEE) of the apparatus 1.

[0047] The apparatus 1 has a changing apparatus 10 which comprises a rotary unit 11 with which the two tufting units 3 and 4 can optionally be moved from their setting-up position 7 into the working position 9. The two tufting units 3 and 4 can be rotated about a common axis of rotation 12 between the working position 9 and their setting-up position 7 by means of the changing apparatus 10. The changing apparatus 10 is constructed in such a manner that, whenever one of the two tufting units 3 or 4 is in the working position 9, the other of the two tufting units 3 or 4 is arranged in the setting-up position 7.

[0048] The figures show that the changing apparatus 10 has a linear unit 13 with which the tufting units 3 and 4 are movable linearly on the changing apparatus 10. The linear movement of the tufting units 3, 4 caused by the linear unit 13 takes place transversely, namely at a right angle, with respect to the axis of rotation 11 of the changing apparatus 10. The linear unit 13, by means of two guide rails 34, defines a linear axis 14, along which the two tufting units 3 and 4 can be moved from a position approximate to the axis of rotation 12 (compare FIGS. 2 and 3) into an outer position on the changing apparatus 10 (compare FIGS. 1, 4 and 5).

[0049] The tufting units 3 and 4 take up the positions approximate to the axis of rotation 12 when the tufting units 3 and 4 are rotated, for the previously described change of position, from the setting-up position 7 into the working position 9 or from the working position 9 into the setting-up position 7 by means of the changing apparatus 10 and the rotary unit 11 thereof.

[0050] The apparatus 1 furthermore comprises a docking apparatus 15. The docking apparatus 15 can be used to fix a tufting unit 3, 4, which is located in the working position 9, in the working position 9 and to centre same in the working position 9. For this purpose, the docking apparatus 15 has two fixing device 35 located at the working position 9 and being in the form of fixing receptacles and in each case two corresponding mating fixing devices 36 in the form of fixing pins at each of the tufting units 3, 4. FIG. 1 shows the first tufting unit 3 at the docking apparatus 15.

[0051] By means of a movement of the tufting unit 3 along the linear axis 14 of the linear unit 13, the docking apparatus 15 is released (compare FIG. 2) and the tufting unit 3 becomes free. The tufting unit 3 can subsequently be moved into the setting-up position 7 by means of the changing apparatus 10.

[0052] Having reached the setting-up position 7, the tufting unit 3 is then moved again along the linear axis 14 of the linear unit 13 into an outer position on the changing apparatus 10.

[0053] The apparatus 1 furthermore comprises a protection device 16 which prevents unauthorized access to the working chamber 8 of the apparatus 1 and bounds the working chamber 8.

[0054] The protection apparatus 16 is in the form of a protective fence. An embodiment of the protection device 16 that is not shown in the figures comprises an electronic access boundary, for example at least one light barrier and/or at least one light curtain, by means of which the working chamber 8 of the apparatus 1 is bounded.

[0055] The protection device 16 can optionally also comprise a switching-off apparatus which, in the event of unauthorized access to the working chamber 8, ensures that the functional units of the apparatus 1 are switched off. This increases the working safety during use of the apparatus 1.

[0056] For a change of position of the tufting units 3, 4, the protection device 16 can be opened in the region of the two tufting units 3 and 4. For this purpose, a fence section 17 of the protection device 16 can be raised so as not to obstruct the rotational movement of the tufting units 3 and 4 about the axis of rotation 12.

[0057] In an embodiment of the apparatus 1 that is not shown in the figures, provision is made that at least part of the protection device 16, for example the previously mentioned fence section 17, is arranged at the changing apparatus 10 and between the at least two tufting units 3 and 4 and, during a movement of the tufting units 3 and 4, is moved together with them.

[0058] The tufting units 3 and 4 are constructed functionally redundantly with respect to one another. Each of the tufting units 3 and 4 shown in the figures has a tufting tool 18, a tie wire feed apparatus 19, a bundle-dividing apparatus 20 and a bristle magazine 21.

[0059] The tufting tools 18 of the tufting units 3 and 4 of the apparatus 1 shown in the figures in each case have changeable pusher tongues 22. This promotes adaptation of the tufting units 3 and 4 in the event of a change of pattern.

[0060] A store of loose bristle filaments is in each case contained in the bristle magazines 21 of the tufting units 3 and 4. In the case of each of the tufting units 3 and 4, bristle bundles 5 can be removed from the bristle magazine 21 by means of the bundle-dividing apparatus 20, by a dividing movement of the bundle-dividing apparatus 20 along the bristle magazine 21, and fed to the tufting tool 18.

[0061] Fastening ties are supplied to the tufting tools 18 by means of the tie wire feed apparatuses 19. By means of a movement of the pusher tongues 22, the fastening ties can then be tufted together with the bristle bundles 5 into provided bristle product bodies 6.

[0062] Within its working chamber 8, the apparatus 1 has a plurality of stations for processing and handling bristle products 2 and bristle product bodies 6. One of the stations is a drilling station 23. Bundle-receiving holes 24 can be produced in provided bristle product bodies 6 in the drilling station 23. A tufting station 25 is provided downstream of the drilling station 23, the tufting station essentially being formed by the two position-changeable tufting units 3 and 4 of the apparatus 1. Downstream of the tufting station 25, the apparatus 1 has a milling station 26. Tufted bristle bundles 5 can be trimmed in the milling station 26.

[0063] Downstream of the milling station 26, the apparatus 1 has a handling station 27. In the handling station 27, bristle product bodies 6 can be placed into the apparatus 1 or finished bristle products 2 removed from the apparatus 1.

[0064] The previously mentioned stations 23, 25, 26 and 27 are arranged uniformly distributed around a transport apparatus 28. The transport apparatus 28 has a plurality of transport holders 29 with which bristle products 2 and/or bristle product bodies 6 can be moved within the working chamber 8 between the stations of the apparatus 1. The transport holders 29 are movable on a plurality of axes in order to carry out positioning movements. Bristle products 2 and/or bristle product bodies 6 can thus be positioned as required by means of the transport holders 29 for processing and/or handling at the stations 23, 25, 26 and 27.

[0065] The apparatus 1 furthermore comprises a controller 30 which is configured for activating the functional units of the apparatus 1. Specifically, the controller 30 is configured for activating the tufting units 3, 4 of the changing apparatus 10, the protection device 16 and the stations 23, 25, 26, 27 and also the transport apparatus 28.

[0066] The controller 30 comprises a data interface 31 via which the controller 30 can be at least temporarily connected to a cloud-based data memory 32. The cloud-based data memory 32 is at least temporarily part of the apparatus 1 and contains data, such as, for example, production program data, process parameters, servicing data, maintenance data, setting-up data and/or data relating to the tufting units 3 and 4. The abovementioned data are available in the cloud-based data memory 32 for retrieval and for use by the controller 30.

[0067] The controller 30 is also configured for describing the data memory 32 and for storing corresponding data in the data memory 32. The two arrows denoted by 33 symbolize a bidirectional data connection between the controller 30 and the data memory 32.

[0068] The diverse remaining arrows shown in the figures symbolize a movement of the functional units of the apparatus that are marked by the arrows.

[0069] The invention is concerned with improvements in the technical field of bristle product production. For this purpose, an apparatus 1 is proposed which has at least two, preferably redundant tufting units 3 and 4 which can be alternately moved from a setting-up position 7 outside a working chamber 8 of the apparatus 1 into a working position 9 within the working chamber 8 and vice versa, in particular such that, whenever one of the at least two tufting units 3 or 4 is in the setting-up position 7, another of the at least two tufting units 3 or 4 can be or is arranged in the working position 9.
