    Process for the production of brushes and
    Brush manufacturing machine
    The invention relates to a method for the production of brushes and a brush production machine with an assembly device on which bristle carriers are equipped with bundles of bristles.
    Such methods and devices are known from practice in different embodiments.
    To produce the brushes, the bristle carriers, which are usually in the form of so-called plastic carrier plates, are delivered in bulk. The loose bulk goods, for example loose bristle carriers delivered in bags, are fed to the brush production machine. However, it is necessary to separate and orient the bristle holders in order, for example, to attach bristle bundles to the bristle holders and to be able to produce the brushes.
    Separating devices, for example so-called vibrating pots, are used for this. The loose bristle carriers are sacked into these vibrating pots and brought into a corresponding orientation with the help of a vibrating movement and also separated from one another. The bristle carriers separated and oriented in this way can then be fed to downstream processing stations of the brush production machine.
    However, the use of such separation devices is comparatively complex. If the design of the bristle carrier changes, it may also be necessary to redesign the separating device in a complex manner or to replace it with separating devices of correspondingly different design.
    BE2018 / 5331
    As a rule, such separation devices are supplied, that is, they are not manufactured by the manufacturers of brush manufacturing machines themselves. Since the separating devices and the feed devices connected to them are then highly individualized devices and machines, there can be comparatively long delivery times which unnecessarily delay the entire development and implementation process of the brush manufacturing machines. In addition, these separation devices and the feed devices that may be required are comparatively expensive.
    It is therefore the object of the invention to provide a method and a brush production machine of the type mentioned at the outset which simplify the production of brushes and increase the flexibility of the brush production when a design or model is changed.
    This object is achieved by a method for producing brushes which has the means and features of the independent claim directed to such a method. In particular, a method for producing brushes is proposed to solve this problem, in which bristle carriers are injection molded within a brush manufacturing machine and are loaded with bristle bundles after injection molding.
    In this way, the manufacture of the bristle carriers can be integrated directly into the actual manufacturing process of the brushes. The previously described, comparatively complex handling of the bristle carriers previously supplied as loose bulk goods can be completely dispensed with.
    Another big advantage is that comparatively small injection molding devices, which are also known as micro injection molding machines
    BE2018 / 5331 can be used. These micro injection molding machines are comparatively inexpensive to buy and maintain. They are also particularly well suited to injection molding bristle carriers that have a comparatively small shot weight. So far, bristle carriers of this type have been produced on comparatively oversized injection molding machines. However, the use of such oversized injection molding machines is particularly disadvantageous when the design of the bristle carrier changes due to the high mold costs. In addition, comparatively long delivery times are also to be feared here, which can delay a model change or even minor adjustments unnecessarily long.
    It may be advantageous if the injection molded carriers are cooled or cooled before they are loaded with bristle bundles. For this purpose it can be provided that the injection molded bristle carriers are fed to a cooling section within the brush production machine. The injection-molded bristle carriers can remain on this cooling section for a defined period of time until they have reached a temperature which permits further processing of the bristle carriers.
    After the injection molding, the bristle carriers can also be fed to a conveying device and transported with the conveying device to an equipping device of a brush manufacturing machine. The bristle carriers can then be equipped with bundles of bristles in or on this assembly device. It can also be advantageous if the bristle carriers are injection molded in an injection molding device of the brush manufacturing machine and, after the injection molding, preferably, directly, from the injection molding device to one or the conveying device already mentioned above. in this connection
    BE2018 / 5331, the bristle carriers can be removed from the injection molding devices and, preferably immediately thereafter or directly, then fed to the conveying device in an orientation and / or order required for further handling and / or processing. The bristle carriers are particularly preferably arranged on a conveyor belt of the conveyor device and placed in an orientation required for further processing and / or handling.
    The aforementioned object is also achieved by a brush production machine of the type mentioned at the outset, which has the means and features of the independent claim directed to such a brush production machine. In particular, in order to achieve the object in the brush production machine of the type mentioned at the beginning, it is proposed that the brush production machine have at least one injection molding device for producing bristle carriers. In this way, a brush manufacturing machine is provided which can be set up to carry out the method described above and claimed in the corresponding claims.
    It can be advantageous if the brush production machine also has a conveyor device. Through this conveying device, the at least one injection molding device of the brush manufacturing machine can be connected in terms of conveying technology to the assembly device of the brush manufacturing machine. A direct coupling between the at least one injection molding device and the assembly device is thus generated. Thus, bristle carriers can get from the injection molding device to the assembly device and / or be transferred to it immediately after their production. This can be particularly preferred in one for further processing of the
    BE2018 / 5331
    Bristle holder necessary orientation of the bristle holder happen.
    If the at least one injection molding device and the loading device and / or the conveying device of the brush manufacturing machine are arranged together on a frame of the brush manufacturing machine and / or together within an enclosure of the brush manufacturing machine, a particularly compact brush manufacturing machine can be created. In addition, a brush production machine is created in this way, which represents a fully functional unit and in which the production of the individual bristle carriers is fully integrated into the brush production machine.
    The brush manufacturing machine, in particular the conveyor device, can also have at least one cooling section. The freshly injection-molded bristle carriers can be placed on this cooling section and remain there until they have reached the temperature required for further processing of the bristle carriers. It can be particularly advantageous if the cooling section is designed as a conveyor belt which runs between the injection molding device and the loading device. The length of the conveyor belt and its conveying speed can be selected so that the bristle carriers have sufficient time to cool down to the temperature required for the further processing of the bristle carriers until they have reached the loading device. It can be particularly advantageous if the brush manufacturing machine, in particular the conveying device, has such a cooling section for each injection molding device of the brush manufacturing machine.
    The brush manufacturing machine, in particular the conveyor device, can have at least one transfer gripper. With the help of
    BE2018 / 5331 at least one transfer gripper can transfer the injection-molded bristle carriers from the at least one injection molding device to one, for example the cooling section already mentioned, from the at least one injection molding device to the mounting device and / or from one, for example the cooling section already mentioned to the mounting device become. It can be particularly advantageous if the brush production machine, in particular the conveying device, has a transfer gripper which is provided for transferring bristle carriers from the injection molding device to the cooling section and comprises at least one further transfer gripper which transfers the bristle carriers from the conveyor device, in particular of the cooling section mentioned above, is used on the placement device.
    Furthermore, it is possible for the brush production machine, in particular the conveyor device, to comprise at least one transport line. This transport line can be designed as a transport hose. The at least one injection molding device and the placement device can be connected to one another in terms of conveying technology with the transport line. Through the at least one transport line of the brush manufacturing machine, in particular the conveying device, the bristle carriers can be transported from the injection molding device to the assembly device immediately after their production by means of compressed air and / or vacuum. This form of transport is particularly advantageous since the cooling of the injection-molded bristle carrier can also be accelerated with the aid of the air or compressed air flowing through the at least one transport line.
    The at least one injection molding device can be a micro injection molding machine. Such a micro-injection molding machine can also be particularly easily, if appropriate, also in
    BE2018 / 5331 integrate existing brush manufacturing machines. In addition, such micro-injection molding machines are particularly suitable for producing bristle carriers that have a comparatively small shot weight. In addition, the tools and / or molds provided in such micro-injection molding machines for producing the bristle carriers are comparatively compact and therefore inexpensive. Overall, such micro-injection molding machines allow a particularly flexible design and, if necessary, adaptation of the manufacturing process in the manufacture of brushes.
    An exemplary embodiment of the invention is described in more detail with reference to the following drawing. It should be pointed out that the invention is not restricted to the exemplary embodiment shown in the figures. Further exemplary embodiments of the invention also result from a combination of the features of individual or more claims with one another and / or in combination with individual or more features of the exemplary embodiment shown in the figures. They show in a partially highly schematic representation:
    Fig. 1 is a plan view of a brush manufacturing machine, two injection molding devices and a placement device can be seen, which are connected to each other by a conveyor device, and
    Fig. 2 is a cross section of a transport line shown in Figure 1 with a bristle carrier shown therein, also shown in section.
    FIG. 1 shows a brush production machine, designated as a whole by 1, with a placement device 2, on which bristle carriers 3 can be fitted with bundles of brushes.
    BE2018 / 5331
    To manufacture the bristle carriers 3, the brush manufacturing machine 1 has a total of two injection molding devices 4.
    The brush manufacturing machine also has a conveyor device 5 between the two injection molding devices 4 and the loading device 2. The two injection molding devices 4 and the placement device 2 are connected to one another in terms of conveying technology by the conveying device 5. In this way, the injection-molded bristle carriers 3 can be transported from the injection molding devices 4 to the placement device 2 immediately after their manufacture. Separate handling of the bristle carriers, for example as bulk goods, can thus be dispensed with.
    The two injection molding devices 4 and the loading device 2 are arranged together with the conveying device 5 together on a frame 6 of the brush manufacturing machine 1 and are also positioned together within a housing 7 of the brush manufacturing machine 1.
    The conveying device 5 has a cooling section 8 for each of the two injection molding devices 4. The bristle carriers 3 can be placed on this cooling section 8 before they are transferred to the placement device 2 for cooling. The cooling sections 8 shown in FIG. 1 are conveyor belts 9 which run between the injection molding devices 4 and the loading device 2.
    The conveyor device 5 of the brush manufacturing machine 1 further comprises two transfer grippers 10, 11. With the aid of the first transfer gripper 10, the injection molded bristle carriers 3 are transferred from the injection molding devices 4 to the respective cooling section 8. The
    BE2018 / 5331 placed on the cooling section 8 bristle carrier 3 up to one
    Delivery end of the cooling sections 8 transported and with the help of the second
    Transfer gripper 11 from the respective cooling section 8 to the
    Transfer assembly device 2.
    In addition to the two cooling sections 8 and the transfer grippers 10 and 11, the conveying device 5 of the brush manufacturing machine 1 has a transport line 12. This one transport line 12 is designed as a transport hose and connects one of the two injection molding devices 4 directly to the loading device 2 of the brush manufacturing machine 1 in terms of conveying technology. Through the transport line 12, the bristle carriers 3 produced with this injection molding device 4 can be transported from the injection molding device 4 directly to the mounting device 2 by means of compressed air and / or with a vacuum.
    The two injection molding devices 4 of the brush manufacturing machine 1 are so-called micro-injection molding machines. These are comparatively small and can also be particularly easily integrated into existing brush manufacturing machines 1.
    With the previously described brush manufacturing machine 1, the method for manufacturing brushes described below can be carried out.
    It is provided that the bristle carriers 3 are injection molded within the brush manufacturing machine 1 and are loaded with bristle bundles after the injection molding. The bristle holders 3 are injection molded in the two injection molding devices 4 of the brush manufacturing machine 1 shown in FIG. 1. The bristle holders 3
    BE2018 / 5331 are in the placement device 2 of the
    Brush manufacturing machine 1 equipped with bristle bundles.
    The injection molded bristle carriers 3 can be cooled or cooled before they are loaded with bristle bundles. For this purpose, the injection-molded bristle carriers 3 are fed to the cooling sections 8, which are designed as conveyor belts 9 and run between the injection molding devices 4 and the placement device 2.
    After the injection molding, the bristle carriers 3 are fed to the conveying device 5 and transported with the conveying device 5 to the loading device 2 of the brush manufacturing machine 1. The bristle carriers 3 are equipped with bundles of bristles in or on the placement device 2.
    After the injection molding of the bristle carriers 3, they are automatically removed from the respective injection molding device 4 and immediately fed to the conveyor device 5, here the conveyor belt 9, which also serves as a cooling section 8. In this case, the individual bristle carriers are arranged and placed on the respective conveyor belt 9 of the conveyor device 5.
    The invention is concerned with improvements in the technical field of manufacturing brushes. For this purpose, among other things, the method for producing brushes is proposed, in which it is provided that bristle carriers 3 are injection molded within a brush production machine 1 and are loaded with bristle bundles after the injection molding.
