    专利说明:

    The invention relates to a bundle removal device with a material box for receiving a supply of loose bristle filaments, with a compartment device for removing bristle bundles from the material box and with a transport device for transporting bristle bundles removed from the material box to a production section downstream of the bundle removal device, in particular a downstream processing station a brush making machine.
    Furthermore, the invention also relates to a brush production machine with such a bundle removal device.
    Such bundle removal devices and brush manufacturing machines are known in practice in various embodiments. With the help of the compartment device of the bundle removal device, individual bristle bundles from a stock of loose bristle filaments, which is held in the material box of the bundle removal device, are separated and removed and then by means of a transport device, for example via compressed air and / or negative pressure, for further processing of the bristle bundles, in particular their attachment to a bristle carrier, for example a toothbrush, passed on.
    Despite the well-known technology of the already known bundle removal devices, it can happen that when bristle bundles are removed from the material box, individual bristle filaments fall out of the compartment device, are struck or kinked by it and / or finally in the area of the compartment device, the transport device or also the Material box or other areas
    BE2019 / 5065 of the bundle removal device remain. If the loose, possibly chipped and / or kinked bristle filaments get into downstream production sections, in particular processing stations of a brush manufacturing machine, this can impair the process stability in the manufacture of brushes and also impair the quality of the brushes produced.
    Especially if a transport device is used as the transport device in which the bristle bundles removed from the material box with the aid of the compartment device are blown and / or sucked through compressed air and / or negative pressure through a transport line to a downstream processing station, it can also occur that loose and / or damaged bristle filaments accidentally get into feed elements of the transport device, in particular into a transport line or also downstream areas of the transport device, such as so-called suction blocks and their feed channels, and block them.
    The object of the invention is therefore to provide bundle removal devices and a brush production machine of the type mentioned at the outset with which these problems can be reduced or even avoided.
    To achieve this object, a bundle removal device with the means and features of claim 1 is proposed. In particular, the object is achieved in a bundle removal device of the type mentioned at the outset in that the bundle removal device has a suction device for suctioning loose bristle filaments remaining in the area of the compartment device, the transport device and / or the material box.
    BE2019 / 5065
    In this way, when bristle bundles are removed, bristle filaments that have been lost and remain in the aforementioned areas, which can also be damaged, are removed from time to time or also continuously using the suction device. Compared to blowing off the parts of the bundle removal device covered with loose bristle filaments, by means of which the loose bristle filaments can be distributed in an uncontrolled manner within the bundle removal device and also adjacent or downstream processing stations of a brush manufacturing machine or other technical devices, the use of the suction device described above is advantageous. This is because it enables reliable and, above all, targeted removal of loose bristle filaments from the particularly relevant areas of the bundle removal device.
    It can be particularly advantageous if the bundle removal device between the material box and the transport device comprises at least one counterpart assigned to the compartment device. With the aid of this counterpart, bristle bundles removed with the aid of the compartment device can be supported and secured during their transport from the material box to the transport device of the bundle removal device. In this way, an unintentional loss of bristle filaments during transport from the material box to the transport device can be reduced or even completely avoided with the at least one counterpart.
    Furthermore, it is possible for the suction device to comprise at least one suction nozzle. This suction nozzle can be assigned to the at least one counterpart of the bundle removal device. It is possible to reliably remove those bristle filaments that remain or remain on or in the area of the counterpart of the bundle removal device after removing bristle filaments from the material box. It can be particularly advantageous if each counterpart of the bundle removal device is assigned at least one such suction nozzle of the suction device. The bundle removal device can thus have a suction device which has a number of suction nozzles corresponding to the number of counterparts.
    The compartment device, in particular if it is designed as a so-called compartment disk with one or more bundle receiving notches on its circumference, can be arranged between at least two counterparts of the bundle removal device. It is advantageous if each counterpart of the bundle removal device is assigned a suction nozzle.
    If the at least one counterpart, preferably each counterpart of the bundle removal device, is at least partially arranged within the associated suction port of the suction device, the respective suction port can at least partially surround the counterpart for bilateral suction of the counterpart on both sides. In this way, a particularly thorough removal of bristle filaments adhering to the counterpart (s) of the bundle compartment device is possible.
    The advantageous effect of the suction device can be further enhanced if one or each counterpart has an opening. In this way, the air flow caused by the suction device and flowing into the suction nozzle can flow through the areas of the bundle removal device with as little impairment or impairment as possible and thereby take away and remove loose bristle filaments which are arranged adjacent to the respective suction nozzle.
    BE2019 / 5065
    It can be particularly advantageous if the or each counterpart is arranged, at least in part, in the suction connector assigned to it in such a way that the suction connector at least partially surrounds the opening for suction on both sides.
    In order to be able to use the suction device to particularly well detect and remove such loose bristle filaments which adhere to the compartment device, which is arranged between the material box and the transport device, or which remain in the area of the compartment device, it can be expedient if the at least one suction nozzle is one Has suction opening, which faces the compartment device.
    As already mentioned above, the transport device can have at least one feed element, for example at least one transport line, a suction block, a bundle transfer device and / or a suction plate, through the removed bristle bundle to a production section downstream of the bundle removal device, in particular to a processing station of a brush manufacturing machine, can be transported by means of a pressure medium, in particular by means of compressed air and / or negative pressure. It is possible to connect the transport device to a suction device that has a negative pressure at the outlet end of the at least one feed element, in particular the at least one transport line, facing away from the compartment device, and / or to a pressure source or compressed air source of the transport device. In this way, the bristle bundles can be sucked and / or blown through the feed element or elements, in particular through the at least one transport line.
    The aforementioned object is also achieved by a bundle removal device with the means and features of the second independent claim directed to a bundle removal device. in particular
    BE2019 / 5065 is particularly proposed to solve the problem in a bundle removal device of the type mentioned that the transport device has at least one feed element through which removed bristle bundles can be transported to the downstream production section by means of a pressure medium and that the bundle removal device comprises a cleaning device that is set up for this purpose is to remove dirt and / or bristle filaments remaining in the at least one feed element by emitting a compressed air and / or compressed gas pulse from the latter.
    The transport device can have at least one transport line, a suction block, a bundle transfer device and / or a suction plate as feed elements. All feed elements can be provided with feed channels through which the bristle bundles can be transported by means of the pressure medium, usually compressed air and / or negative pressure.
    It should be expressly pointed out that a combination of such a cleaning device with a previously described suction device on one and the same bundle removal device can be possible and particularly advantageous.
    With the help of the cleaning device, soiling and also bristle filaments that possibly get caught in the feed element, in particular in the at least one transport line or also other feed elements of the transport device and threaten to clog them, can be removed in a targeted manner. A compressed air pulse or a compressed gas pulse with a negative or positive pressure of several bars can be sent through a feed channel in the respective feed element or through a feed or transport line of the transport device, so that even stubbornly adhering boron
    BE2019 / 5065 ten filaments or dirt from the feed element, in particular the transport line or other feed elements of the transport device, can be reliably removed.
    A particularly effective cleaning device can be designed, for example, as a compressed air cleaning device. The cleaning device can have at least one pressure source, in particular a compressed air source and / or a pressure sink, in particular a compressed air sink. The at least one supply element, in particular the at least one transport line or also further supply elements of the transport device, can be connected at least temporarily to both the compressed air source and the compressed air sink. Compressed air and / or compressed gas pulses can be emitted onto or into the at least one feed element, in particular the transport line and / or further feed elements of the transport device, for cleaning adhering particles or bristle filament and for loosening or preventing blockages.
    One possibility of being able to blow and / or suck free the transport device and its at least one feed element, in particular at least one transport line and / or further feed elements from time to time, can be that the bundle removal device comprises a guide device with which the at least a feed element, in particular the at least one transport line, of the transport device is to be moved into a cleaning position on the cleaning device. However, it is also possible for the bundle removal device to comprise a guide device with which the cleaning device can be moved into a cleaning position on the at least one feed element of the transport device, in particular on the at least one transport line of the transport device, in order to suck it up and / or blow it free.
    BE2019 / 5065
    In order to be able to transfer the bristle bundles removed from the material box by the compartment device to feed elements of the transport device of the bundle removal device, it can be expedient if the bundle removal device has a bundle transfer device. This can be arranged between the compartment device and the transport device and / or can also be part of the transport device.
    As already indicated above, the compartment device can have at least one bundle receiving notch with which the compartment device can be moved past an open end of the material box against which the bristle filaments are in contact. As soon as the compartment device with its at least one bundle receiving notch passes the open end of the material box, bristle filaments are pressed into the at least one bundle receiving notch and at least one individual bristle bundle is removed from the stock of loose bristle filaments of the material box. In one embodiment of the bundle removal device according to the invention, the compartment device can be designed as a so-called circular arc divider or as a compartment slide. A circular arc divider is often swiveled past the material box in an alternating swiveling or rotating movement. The circular arc divider has at least one bundle receiving notch on its end face facing the material box in the use position.
    The compartment device of the bundle removal device can, however, particularly advantageously be designed as a compartment disk. Such a compartment disk is frequently moved past the material box with its supply of loose bristle filaments either in an alternating rotary or pivoting movement or also only in a continuous rotary movement in one direction. The compartment disc also has at least one bundle receiving notch on its outer circumference, with which
    BE2019 / 5065 individual bristle filaments from the stock of loose bristle filaments can be taken from the material box.
    Finally, the object is also achieved by a brush manufacturing machine with the features of the independent claim directed to a brush manufacturing machine. In particular, a brush production machine is proposed for the solution, which has a bundle removal device according to the invention.
    The invention will now be described in more detail using an exemplary embodiment, but is not restricted to this exemplary embodiment. Further exemplary embodiments result from a combination of the features of individual or more claims with one another and / or with individual or more features of the exemplary embodiment. They show in a partially highly schematic representation:
    Fig. 1: A perspective view of a bundle removal device, which comprises both a suction device for removing loose bristle filaments from the area of the compartment device and a cleaning device for removing bristle filaments from feed elements of the compressed air-operated transport device, and Fig. 2: the bundle removal device shown in Fig. 1, wherein the transport device with its several transport lines is shown in a cleaning position on the compressed air cleaning device of the bundle removal device.
    1 and 2 show a bundle denoted as a whole by 1
    BE2019 / 5065 device. The bundle removal device 1 has a material box 2 which serves to hold a supply of loose bristle filaments 3. In addition, the bundle removal device 1 also comprises a compartment device 4 for removing bristle bundles 5 from the material box 2 and the stock of loose bristle filaments 3 located therein.
    Downstream of the material box 2 and the compartment device 4, the bundle removal device 1 also has a transport device 6, with which the bristle bundles 5, which were removed from the material box 2 with the aid of the compartment device 4, are passed to a downstream processing station of a bristle production machine 7, which is equipped with the bundle removal device 1 is can be transported. The compartment device 4 has a plurality of individual bundle receiving notches 8 on its outer circumference, with which the compartment device 4 can be moved past an open end 9 of the material box 2. The loose bristle filaments 3 are in contact with the open end 9 of the material box 2 and are pressed by a pusher 10 of the material box 2 into the bundle receiving notches 8 of the compartment device 4 when it passes through the open end 9 of the material box 2. As shown in FIGS. 1 and 2, the compartment device 4 is designed as an essentially circular compartment disc, which is rotated about its axis of rotation between the material box 2 and the transport device 6.
    The bundle removal device 1 also has a suction device 11. Using the suction device 11, loose bristle filaments 3 remaining in the area of the compartment device 4, the transport device 6 and / or the material box 2 can be suctioned off and removed, which may have been lost, for example, during the transport of the bristle bundles 5 from the material box 2 to the transport device 6 ,
    BE2019 / 5065
    Between the material box 2 and the transport device 6, the bundle removal device 1 has a total of two counterparts 12 which are assigned to the compartment device 4. The suction device 11 comprises two suction nozzles 13, of which one suction nozzle 13 is assigned to one of the two counterparts 12 of the bundle removal device 1.
    The counterparts 12 surround the compartment device 4 designed as a compartment disc and are intended to prevent bristle bundles 5 positioned in the bundle receiving notches 8 from being lost on their way from the material box 2 to the transport device 6. The end faces of the counterparts 12 facing the compartment device 4 thus serve as stationary limits relative to the rotating compartment device 4, which then limit or close the bundle receiving notches 8 on the outside when the bundle receiving notches 8 are placed in front of the end faces of the counterparts 12 and pass through them.
    As the two figures make clear, each of the two counterparts is at least partially arranged within the suction port of the suction device 11 assigned to it. In this way, the suction nozzle 13 can surround the counterparts 12 assigned to them for suction on both sides, at least partially on both sides, here on the top and on the bottom. This favors a reliable and thorough removal of bristle filaments remaining in the area of the counterparts or also of dirt.
    Both counterparts 12 of the bundle removal device 1, between which the compartment device 4 is arranged, each have an opening 14. The openings 14 represent material-free cross sections through which an air flow caused by the suction device 11 can pass. Each of the two counterparts 12 for BE2019 / 5065 is at least partially arranged in the suction port 13 assigned to it in such a way that the suction port 13 surrounds the respective opening 14 for suction on the underside and bottom, i.e. for suction on both sides, at least partially on the top and bottom and thus on both sides.
    Suction openings 15 of the two suction nozzles 13 face the compartment device 4. In this way, loose bristle filaments that adhere to or on the compartment device 4 can also be removed from the bundle removal device 1 via the two suction connections 13.
    The transport device 6 has a total of six transport lines 16. Through these transport lines 16, the removed bristle bundles 5 can be transported to a downstream processing station of the brush manufacturing machine 7 by means of a pressure medium, here by means of compressed air and / or negative pressure. For this purpose, the transport device 6 comprises a suction station 17 and a suction block 18, into which a total of six transport lines 16 of the transport device 6 open.
    The bundle removal device is also equipped with a cleaning device 19. The cleaning device 19 is used to suck and / or blow free the transport lines 16 of the transport device 6 and also further feed elements of the transport device 6, through which the bristle bundles 5 are transported by means of compressed air and / or negative pressure. The cleaning device 19 is set up to remove dirt and / or bristle filaments 3 remaining in the feed elements of the transport device 6, for example in the transport lines 16, by emitting a compressed air and / or compressed gas pulse.
    BE2019 / 5065
    The cleaning device 19 is designed as a compressed air cleaning device and comprises a compressed air source 20 and a compressed air sink 21, between which the pressure required for blowing out and / or sucking out the transport lines 16 and further feed elements of the transport device 6 is generated and to which the transport lines 16 of the transport device 6 are at least temporarily can be connected.
    The bundle removal device 1 has a guide device 22. In the exemplary embodiment of the bundle removal device 1 shown in the figures, this guide device 22 comprises a total of two sliding guides 23, along which the bristle bundle 5 feeding elements of the transport device 6, in particular the six transport lines 16 of the transport device 6, can be moved into a cleaning position on the cleaning device 19, to at least suck and / or blow free the transport lines 16.
    While the bristle bundles 5 guiding feed elements of the transport device 6 are shown in FIG. 1 in a position on the bundle removal device 1 in which they can be used to transport the bristle bundles 5, they are in their cleaning position on the cleaning device 19 in FIG. 2. Here, the transport lines 16 are arranged between the pressure source 20 and the pressure sink 21 of the cleaning device 19. In this way, a stream of compressed air can be blown into the transport lines 16 through the inlet openings of the transport device 6, while at the same time a negative pressure can be applied to the outlet-side ends of the transport lines 16 with the help of the pressure sink 21, which is designed here as a suction station, which has the effect of the cleaning device 19 can reinforce.
    BE2019 / 5065
    In one embodiment of the bundle removal device 1, which is not shown in the figures, it is provided that it comprises a guide device with which the cleaning device 19 can be moved into a cleaning position on the at least one transport line 16 of the transportation device 6 of the bundle removal device 1, in order to move it at certain intervals Vacuum and / or blow from time to time.
    For the transfer of bristle bundles 5 from the compartment device 4 to the transport device 6, the bundle removal device 1, here the transport device 6, comprises a bundle transfer device 24 as a further feed element. This bundle transfer device 24 comprises a suction plate 25 to which the transport lines 16 of the transport device 4 are connected. The suction plate 25 has suction openings 26, the number and arrangement of which correspond to the total of six bundle receptacles 8 of the compartment device 4.
    In Fig. 1, the total of six bundle receiving notches 8 of the compartment device 4 are positioned in a transfer position relative to the suction plate 25. As soon as a vacuum is now applied to the transport lines 16 by means of the suction station 17 of the transport device 6, bristle bundles 5 held ready in the bundle receiving notches 8 are sucked into the transport lines 16 through the suction openings 26 in the suction plate 25 and, for example, transported to a downstream station of the brush-making machine 7.
    The invention is concerned with improvements in the field of brush manufacturing. For this purpose, the bundle removal device 1 is proposed, which includes the suction device 11, with the loose bristle filaments 3, which are used, for example, when removing boron
    BE2019 / 5065 ten bundles 5 from the material box 2 of the bundle removal device 1 have been lost and / or have been damaged, can be reliably removed. In this way, it can be prevented that such loose bristle filaments 3 are inadvertently placed in downstream areas of the
    Bundle removal device 1 and / or a brush production machine 7 equipped with the bundle removal device 1, where they could possibly lead to process and / or quality impairments in the production of brushes, in particular toothbrushes.
