Definitions

  • the invention relates to an apparatus for producing bristle products, in particular brushes, brooms and/or paintbrushes.
  • DE 1 632 376 A1 has disclosed a brush production machine which comprises a set of tools consisting of a plurality of drilling tools and tufting tools, wherein the number of tufting tools is greater by one than the number of drilling tools, and in each case the tufting tool which is not in operation can be switched off at least to an extent such that no clusters of bristles are output by it.
  • Apparatuses of the type mentioned at the beginning are also known in practice in various embodiments.
  • the previously known apparatuses have tufting units with which bristle bundles can be tufted into provided bristle product bodies in order to produce a stock of bristle bundles.
  • Tufting units of this type can have tufting tools, by means of which bristle bundles previously retrieved from a bristle magazine are tufted together with a fastening tie consisting of a tie wire into a bundle-receiving hole in a bristle product body and anchored there.
  • Apparatuses of this type are often used for producing different bristle product patterns.
  • the change of pattern generally requires diverse adaptations to the apparatus and in particular to the tufting unit thereof. It is thus possible, for example, that, for a change of pattern, what is referred to as a pusher tongue, with which fastening ties together with bristle bundles are tufted into provided bristle product bodies, has to be exchanged. This may also be necessary if the pusher tongue is damaged.
  • a bundle divider of the tufting unit with which bristle bundles can be retrieved from a store of loose bristle filaments, may also need to be adapted.
  • Pattern-dependent adaptations may also be required with regard to a wire feed apparatus, with which tie wire for producing fastening ties can be fed to the tufting tool of a tufting unit. Similar work may also be needed for servicing, repair, setting up and/or maintaining the apparatus. All of these measures necessitate shutting down the apparatus and may reduce its overall equipment effectiveness.
  • an apparatus having one or more of the features disclosed herein directed towards an apparatus for producing bristle products.
  • an apparatus for producing bristle products in particular brushes, brooms and/or paintbrushes, is therefore provided, which apparatus has at least two tufting units for tufting bristle bundles into bristle product bodies, wherein the tufting units are alternately movable from a setting-up position outside a working chamber of the apparatus into a working position within the working chamber and vice versa.
  • an apparatus for producing bristle products which permits setting up, which is necessary in the event of a change of pattern, for example, of one of the at least two tufting units outside the working chamber without the apparatus having to be shut down in the meantime.
  • the other tufting unit While work is being undertaken at the tufting unit located in the setting-up position, the other tufting unit, which is in the meantime in the working position, can continue to be used independently thereof in order to tuft bristle bundles into provided bristle product bodies.
  • the apparatus can therefore continue to be used for producing bristle products even when work is being carried out on one of the at least two tufting units.
  • the apparatus according to the invention provides corresponding advantages also in the event of maintenance or servicing measures. As soon as work has to be undertaken at one of the at least two tufting units, the tufting unit concerned can be moved into the setting-up position outside the working chamber of the apparatus while the other tufting unit can be used within the working chamber in order to produce bristle products.
  • said apparatus has a changing apparatus with which the tufting units can be moved from their setting-up position into the working position.
  • the changing apparatus can be set up for preferably automatically changing the position of the tufting units between their setting-up position and the working position.
  • the changing apparatus can have a rotary unit, for example with a rotary disc, on which the at least two tufting units of the apparatus are arranged.
  • the rotary unit acts as a rotatable and common carrier structure for the at least two tufting units.
  • the tufting units can be rotatable, in particular with the changing apparatus, about a, preferably common, axis of rotation. In this way, the movement of the at least two tufting units between their setting-up position and the working position within the working chamber can take place in a rotational movement.
  • the changing of the position of the tufting units can be undertaken by means of a rotational movement in one direction of rotation or else by an alternating rotational movement.
  • the apparatus in particular the changing apparatus, has a linear unit with which the tufting units are linearly movable.
  • a linear axis of the linear unit can be oriented here transversely or at a right angle with respect to an axis of rotation, for example with respect to the axis of rotation already previously mentioned, of a changing apparatus, for example of the changing apparatus already previously mentioned.
  • the tufting units are rotated about a, preferably common, axis of rotation for changing the position, it may be expedient to move the tufting units beforehand along a linear axis of the linear unit into a position approximate to the axis of rotation. The centrifugal forces occurring when the rotational movement is carried out are thereby reduced.
  • the linear unit can furthermore be used to move, in particular to position, the tufting units located in the setting-up position and/or in the working position.
  • the apparatus can furthermore have a docking apparatus with which a tufting unit located in the working position can be fixed and/or can be aligned, in particular can be centred, in the working position.
  • the docking apparatus can have at least one fixing device located in the working position and preferably in each case at least one corresponding mating fixing device at each of the tufting units.
  • the previously mentioned linear unit can be used to position the tufting units into the active region of the docking apparatus in the working position or to release the tufting units from the docking apparatus.
  • the apparatus can furthermore have a protection device which bounds the working chamber.
  • the protection device can be configured to prevent an unauthorized access to the working chamber of the apparatus.
  • the protection device can have a switching-off apparatus with which functional units of the apparatus, in particular the tufting units, are deactivated as soon as access to the working chamber of the apparatus is established.
  • the protection device can comprise a protective fence and/or an electronic access boundary.
  • the protection device can have, for example, at least one light barrier and/or at least one light curtain as the electronic access boundary. If the protective fence is opened, the switching-off apparatus can deactivate functional units of the apparatus.
  • the switching-off apparatus can be connected to the light barrier and/or to the light curtain. If the light barrier and/or light curtain is/are switched on because of unauthorized access to the working chamber, the switching-off apparatus can be activated to switch off the functional units of the apparatus.
  • the protection device can be temporarily deactivatable and/or openable for changing the position of the tufting units between their setting-up position and the working position.
  • the protection device in particular a fence section, is arranged between the at least two tufting units on the changing apparatus and, during a change of the position of the tufting units, is movable together with them. In this way, opening of the protection device for a change of the position of the tufting units can take place by means of the tufting unit movement undertaken for the change of position.
  • the tufting units of the apparatus are preferably functionally redundant with respect to each other.
  • the function of a tufting unit which is in the setting-up position can thus be taken over by a tufting unit of the at least two tufting units that is arranged in the working position.
  • Each tufting unit can have at least one tufting tool and/or at least one tie wire feed apparatus and/or at least one bundle-dividing apparatus and/or at least one bristle magazine.
  • Bristle bundles together with fastening ties can be tufted into provided bristle product bodies by means of a tufting tool.
  • a tie wire feed apparatus can be used to feed tie wire for fastening ties to the tufting tool.
  • a bundle-dividing apparatus can be used to retrieve bristle bundles from a store of loose bristle filaments which can be stored in a bristle magazine of the tufting unit. By means of a corresponding movement of the bundle-dividing apparatus, bristle bundles can be divided from the bristle store and fed to the tufting tool.
  • the apparatus can be retrofitted to another bristle product pattern in a comparatively simple manner, it may be expedient if at least one tufting tool of a tufting unit has an exchangeable pusher tongue.
  • the apparatus can have, preferably within the working chamber, at least one station for processing and/or handling bristle products and/or bristle product bodies.
  • a tufting station, a milling station, a drilling station and/or a handling station can be provided as the station.
  • the tufting units which are changeable in their positions can be assigned to a tufting station of the apparatus that is arranged at the previously defined working position.
  • the tufting units of the apparatus can be used to tuft bristle bundles into the bundle-receiving holes produced in the drilling station.
  • tufted bristle bundles can be trimmed, in order to provide the set of bristles of the bristle products with a certain contour.
  • the apparatus can have a transport apparatus with at least one transport holder with which bristle products and/or bristle product bodies are movable within the working chamber between stations of the apparatus.
  • bristle product bodies to be processed can be introduced into the working chamber of the apparatus and finished bristle products can be removed from the working chamber and optionally delivered to a downstream process step.
  • the transport holder already mentioned previously can be set up to clamp bristle product bodies and/or bristle products and/or can be movable in order to position the bristle products and/or bristle product bodies on a plurality of axes.
  • the apparatus can have a controller for activating functional units of the apparatus, in particular for activating the at least two tufting units, the changing apparatus already mentioned previously, the protection device and/or the at least one station of the apparatus, which station has already been mentioned previously and is arranged within the working chamber.
  • the controller can comprise a data interface.
  • the controller can be connected at least temporarily to a data memory and/or can be configured for preferably bidirectional communication with the data memory via the data interface. From the data memory, the controller can read data stored in the data memory for the production, servicing, maintenance and/or setting up of the apparatus.
  • the controller can also be configured to describe the data memory and to store corresponding data in the data memory.
  • the data memory with which the controller can communicate via its data interface is preferably a cloud-based data memory.
  • the apparatus can therefore at least temporarily have a preferably cloud-based data memory, preferably in which production program data, process parameters, servicing data, maintenance data, setting-up data and/or data relating to the tufting units are stored for retrieval by the controller.
  • a dedicated data set can be stored in the cloud-based data memory. It is thereby possible to enable the apparatus via the cloud-based data memory to produce new bristle product patterns. This can take place from afar, for example by means of the manufacturer of the apparatus. This permits a retrospective functional adaptation of apparatuses already delivered for producing bristle products.
  • the controller can also store data, in particular data which have been collected by the apparatus, for example via at least one sensor of the apparatus, in the data memory. The data are then available there optionally for evaluation and/or for use by other apparatuses for producing bristle products.
  • the apparatus has at least one sensor for data acquisition.
  • process parameters, servicing data, production program data, maintenance data, setting-up data and/or data relating to the tufting units of the apparatus can also be stored via the data interface in the data memory for analysis and/or use by other apparatuses for producing bristle products.
  • All of the previously mentioned data can also be data which, for example, have been produced automatically or else have been input or read in by an operator during the setting up, servicing, maintenance or use of the apparatus for producing bristle products.
