    专利说明:

    The invention relates to a brush making machine with a bristle feed from a stock of bristles to a cassette or a similar pile receptacle with receiving openings for individual bristle tufts, the brush making machine having a tuft separator with a receiving notch for taking tufts of bristles from the stock of bristles.
    Brush making machines of the type mentioned at the beginning are already known in various embodiments. Thus, brush making machines are known in which the tufts of bristles taken from a stock of bristles by means of a tuft separator are brought to an insertion tool, are folded approximately in the middle and are then inserted with a small anchor plate into a brush body.
    However, the brushes are often processed without an anchor and not bent in an in-mold process, in which the tufts of bristles are placed in a perforated cassette or plate with tufts receiving openings, the The cassette or perforated plate is placed in a mold cavity and the tuft ends protruding from the perforated plate or plate are coated with synthetic material to form the brush body at an injection molding station.
    Document DE 40 40 297 A1 discloses a device in which tufts of hair are taken from a stock of hair and are brought into a temporary storage unit from which the tufts of hair are transferred into a brush body or a brush. perforated plate as intermediate support.
    This temporary storage unit however requires space and requires complex control. The problem is therefore to create a brush making machine of the type mentioned at the beginning which is simple to make and compact.
    The solution according to the invention to this problem is that there is provided a packing site for transferring a tuft of bristles from the tuft separator to the tuft receptacle, in that it is provided in the region of the packing site. a tuft pusher movable between a feed position and a hold position, for removing the tuft of bristles from the receiving notch of the tuft separator and for retaining the tuft of bristles between the tuft pusher and a tuft of tuft between a tuft support opposed therefrom, and in that an axially sliding ejector is provided for exerting pressure on the front side of the tuft of bristles and ejecting the tuft of bristles retained between the tuft pusher and the tuft of tuft. tuft support in the tuft receptacle.
    In this way, a tuft of bristles is directly transferred from the tuft separator into a tuft receptacle. Expensive and complex temporary storage units are not needed. In addition, the size of the brush making machine is significantly reduced.
    It is appropriate that the tuft pusher has an abutment zone for the tuft of bristles carried by the tuft separator. In the forward dead center of the tuft separator, the tuft of bristles is adjacent to the stop zone which forms a guide for the tuft of bristles as the tuft pusher moves into the retaining position.
    In this case, it is particularly appropriate for the tuft pusher to be fork-shaped and have a larger fork leg to form the abutment zone and a shorter fork leg with an inclined sliding surface for the tuft of tuft. bristles, which sliding surface is oriented towards the longer fork leg. A receiving area for the tuft of bristles, in which the tuft of bristles is reliably retained when removed from the receiving notch, is formed between the two fork legs. With the aid of the inclined sliding surface, individual filaments possibly oblique can also be grasped and aligned in such a way that an ordered tuft of hairs is always retained in the retaining position between the tuft pusher and the tuft. tuft support.
    To prevent individual filaments of the tuft of hair from falling during the forward movement of the tuft separator between the stock of bristles and the packing site and to maintain all the tuft of tufted hairs, it is advantageous that the tuft separator is guided against an edge cover externally closing the receiving notch and following, in the region of the packing site, a pressure lever movable between a guide position adjacent to the tuft separator and a position of ejection of tuft of hair. The pressure lever allows the tuft of bristles to continue to be held in the receiving notch in the region of the packing location when the tuft pusher is in the delivery position, but when The tuft pusher moves into the retaining position and can be expelled from the receiving notch to be retained between the tuft pusher and the tuft support.
    A preferred embodiment in this case provides that the pressure lever can be tilted against the restoring force of a return spring of the guide position in the tufted ejection position. This can be achieved, in terms of construction, particularly simple and therefore inexpensive and congestion for this purpose is minimal.
    Instead, the pressure lever can be moved via an eccentric drive between the guide position and the tufted ejection position. This eccentric drive may, if desired, be coupled to an eccentric drive for the tuft separator and / or tuft pusher.
    Especially when the brush-making machine is an "In-mold" installation in which the tuft-shaped tuft-shaped tuft receptacle is placed directly into an injection molding mold and the tuft of bristles are injection-coated to form the brush body and to connect them at the same time with it but also when the tufts of bristles are first transferred from the tuft receptacle into another cassette, it is appropriate that the receiving openings of the tuft receptacle are configured as passage openings. To avoid in this case that the tufts of hair fall, especially in the case of a vertical working direction, it is appropriate that a blanket or hole pins insertable locally in the receiving openings can be applied to the side the tuft receptacle opposite the filling side with tufts of bristles. The hole pins may also, in this case, penetrate at different depths into the individual receiving apertures to form a hair zone profile.
    A preferred embodiment provides, in this case, for the tuft receptacle to have an area of tufa holes that is adapted to the tuft area of a brush to be produced. Tufts of hair can then be transferred directly to another cassette. Alternatively, the tuft receptacle may be transferred, without further novel tufture arrangements, to an injection device for injection coating the tufts of bristles at their end end and thereby connecting them to the brush body.
    Before placing the tuft receptacle in an injection device, the tufts of bristles retained in the tuft receptacle may, if appropriate, be brought to other machining stations, for example to round and / or profile the free ends of the tufts or to melt the ends of the tufts lying on the side of the brush body.
    If, at the usual high working speeds of, for example, 10 tufts per second, individual filaments of the tufts of bristles are not picked up by the ejector and these individual filaments remain in the region of the lining place, these may build up over time and hinder or block the movement of the tuft pusher. To avoid overload damage in this case, the tuft pusher may have a drive with overload protection. With the aid of the overload protection, the drive for the tuft pusher or the entire brush-making machine can be stopped if necessary.
    An exemplary embodiment of the brush making machine according to the invention will be explained in more detail below on the basis of the drawings.
    In a schematic representation,
    Fig. 1 shows a top view of a hair supply from a stock of hair to a packing site, and FIG. 2 shows a side sectional view of the arrangement of FIG.
    A brush-making machine has, according to the figures, a bristle feed 1 for bringing tufts of bristles 2 of a stock of bristles 3 (FIG. 1) to a tuft receptacle 4 in the form of a cassette (FIG. 2). The hair supply 1 has, as can be seen in Figure 1, a tuft separator 5 with a receiving notch 6 for taking tufts of hair in the stock of hair 3. The tuft separator 5 can at this end be tilted (arrow Pf1) between a tuft receiving position with the receiving notch 6 disposed in the region of the stock of bristles 3 and a tuft unloading position in which the receiving notch 6 is disposed in the region of a packing site 7.
    The tuft separator 5 is guided on an edge cover 8 by which the receiving notch 6 is covered during the transport of a tuft of bristles and the tuft of bristles is thus retained in the receiving notch 6. In the 7, a pressure lever 9 follows the edge cover 8. The tuft separator 5 is tilted until the tuft of bristles retained in the receiving notch 6 abuts in the region of lining against a fork leg 10a of a tuft pusher 11. Next, the tuft pusher 11 is moved axially (arrow Pf2) from the supply position shown in FIG. 1 in a retaining position. In doing so, the tuft of bristles is fixed between the longer fork leg 10a and a shorter fork leg 10b and retained in the receiving space between the two fork legs 10a, 10b. The shorter fork leg 10b further has an inclined sliding surface 12 for the tuft of bristles by means of which individual filaments of the optionally oblong tuft of bristles can be securely grasped and aligned.
    The tuft pusher 11 is pushed until the tuft of bristles is held between the tuft pusher 11 and a stationary tuft support 13. In this case, the pressure lever 9 is also tilted against the restoring force of the tuft 11. a return spring 14, a recess for the pressure lever 9 being provided on the tuft support 13 so that the pressure lever can be tilted far enough.
    In the region of the packing area 7 is disposed a tuft receptacle 4 in the form of a cassette (Fig. 6) which can be positioned, via a not shown positioning drive, each time with one of its receiving openings 15 below the tuft of bristles retained between the tuft pusher 11 and the tuft support 13. With an axially displaceable ejector 16 (arrow Pf3), the tuft of hair in question, retained between the tuft plunger 11 and the tuft support 13 can be impacted on the front side and pushed into a receiving aperture 15 of the tuft receptacle 14. In order for the tuft of bristles 2 not to fall vertically oriented receiving apertures, there is provided a cover 17 on the side of the tuft receptacle 4 which is opposite to the filling side.
    A tuft receptacle 4 completely filled with tufts of bristles 2 can then be brought to a subsequent machining device where the tufts of bristles are, if appropriate, transferred to another cassette, rounded, polished, melted and are in particularly provided in an injection molding mold for injection-coating the tips of molten tufts to form the brush body.
