Definitions

  • the invention relates to a method and an apparatus for producing brushes, with a base part which forms at least a portion of the brush and are fastened to the bristles.
  • a brush body is provided with an array of holes ("hole pattern") corresponding to the desired arrangement of bristles. Bundles or tufts of bristles are then inserted into the holes of the brush body and anchored therein by means of impressed small metallic anchors or by means of loops.
  • the bristle tufts are attached to a small brush head plate without the use of loops or anchors. and the carrier plate is then inserted into or attached to a brush body or handle.
  • brush handles are made with a hole pattern that corresponds to the desired tuft pattern. Bristle tufts are then inserted into these holes and attached to the brush handles. The attachment ends of the tufts are then covered with a small plate.
  • the bristles are trimmed on the front side (that is to say in the direction of the brush surface, which represents the working surface of the brush) and / or on the back side.
  • the trimming is done either before the bristles are attached to the base part or after fixing to the base part.
  • bristles are tufted in tufts from the front side into openings of the base part and / or of a guide part adjacent to the back of the base part in order to project out of the guide part at the rear.
  • a sharp knife is then moved along the guide member to cut off the bristles at the back.
  • the guide part serves as a counter knife and as Support for the moving knife. Overall, this leads to high blade wear.
  • bristles are also trimmed on the front side, especially after they have been attached to the base part by anchor plates.
  • This front trimming is used in particular for profiling the brush surface so that the brush surface, for example, receives a toothed profile in side view.
  • This front trimming which must be done as accurately as possible, is usually done in several stages from coarse to fine. In this case, successively connected profile cutters are used. This applies in particular to very deep cutting profiles.
  • Cropping on the front is used in particular for brush blanks with bristles or bristle bundles fixed in advance on the brush body.
  • the shows DE 32 37 885 A1 a method and an apparatus for cutting a screw in a cylindrical roller brush or the GB 2 286 519 a method and a device for cutting bristle bundles already fastened to a brush body to different lengths, in which the bristles are respectively cut with heated tools.
  • the object of the invention is to provide a method and a device with which a brush can be produced in a cheaper way.
  • the method according to the invention provides for a so-called hot knife, which contacts the bristles and, on the basis of its heat development alone or due to the heat development and the cutting geometry, separates before it is fastened to the base part.
  • the bristles can also be cut after fixing to the base part with the heated tool.
  • the hot knife may also be used for cutting the bristles or bristle tufts prior to feeding to the base part, e.g. generally for cutting the bristles outside the device for making the brushes or for cutting the bristles in a bristle magazine.
  • the cutting should be carried out on bristled base parts.
  • the heated tool works practically wear-free and can be moved with a high cutting speed across the bristles.
  • the cutting speed in the preferred embodiment is about 1 to 2.5 m / minute.
  • the temperature of the heated tool in the cutting area is about 500 ° C +/- 70 ° C.
  • the bristles are made of thermoplastic.
  • the heated tool in the cutting area comprises an electrical resistance heater or itself forms an electrical resistance heater.
  • One way to implement such a tool is to work with a heated wire that cuts the bristles.
  • the heated wire can in principle have any cross-sectional shape.
  • the variant which has proved to be an optimized embodiment in experiments consists in the use of a flat wire.
  • This flat wire is in particular obliquely moved obliquely to the bristles to lead away the cut ends of the trimmed ends.
  • the bristles before their attachment to the base part of the openings in the base part protrude the back and be trimmed on the back of the base part.
  • This embodiment is particularly advantageous in brushes in which the bristle tufts are first inserted into the openings of the base part and are moved over a profiled pressure part to different degrees in the openings to produce a profiled brush surface.
  • the tool geometry (in the case of a wire, the wire geometry) and the temperature of the tool are to be matched to the bristle geometry such that bristles, in particular bristles of a tuft, or neighboring bristle tufts are also welded together by the cutting.
  • the trimmed ends become so soft when cutting and stick together. This can have advantages, for example in that the not yet fixed bristles are already fixed in position.
  • the base part can be aligned during cutting so that the cut bristle ends fall past the bristles. It is to be avoided that the partially soft bristle sections fall on the bristle ends on the base part in order to bond with them.
  • the cutting process is performed overhead, that is, projecting downwards with the bristle ends to be cut off, or with bristles lying substantially horizontally, so that the cut ends fall laterally along the bristle tufts. In the latter case, the tool is moved vertically along the side of the base part along.
  • the heated tool can be moved away from the base part and without supporting body when cutting transversely to the bristles.
  • a supporting part which acts as a counter knife contacted by the knife and absorbs, for example, bristle ends to be circumcised, would be worn away by the tool traveling along it, which can be avoided by the invention.
  • a first cut is performed with the heated tool, and then further trimmed over an unheated cutting tool, so to speak a fine cut performed. That the trimmed bristle ends easily stick together when processed by the hot tool may be advantageous for subsequent trimming since adjacent bristles support the bristle to be cut, which lessens bristles overall and provides a cleaner cut.
  • the attachment of the bristles or bristle tufts on the base part can be done by means of separate anchor plates, by gluing, welding and / or encapsulation on the base part.
  • the base part having a perforated field may be a separate, in particular platelet-shaped part, which is located on the rest of the body Brush body is attached or can be embedded in the injection of the brush body in this, or that the base part is a one-piece, that is from the beginning an integral part of the brush body and thus represents only a portion thereof. Yet another possibility is that the base part is welded to the rest of the brush body.
  • the brush body usually comprises a handle and a head portion, wherein in the / on the head portion, the base part is provided.
  • the device according to the invention for producing a brush in particular for carrying out the abovementioned method according to the invention, comprises a removal device for bristle tufts or bristles (bristle separating device), a transport device for bristle tufts or bristles to form a base part forming at least part of a brush body and a heated tool for trimming the brush bristles. Again, there must be contact between the tool and the bristles to be trimmed to transfer the heat directly from body to body (tool to bristle).
  • the device according to the invention also comprises a fastening device in which the trimmed bristles are fastened, in particular in tufts, to the base part.
  • the device according to the invention has a plurality of processing stations, which are traversed successively from the base part.
  • an index table generally speaking a ring or a rotating circle with brackets, a circumferential chain with brackets or the like is advantageous.

  • the bristle tufts 16 are so deeply into the base member 12 and the guide member 26 from the back of the base member 12, that is, from the back of the brush 10, pushed in that they protrude from the front of the guide member 16 again and abut against the stop member 30.
  • the stop member 30 is removed. Instead, a pressure member 32 is moved from the front axially to the bristle tufts 16 upwards, so that it contacts all the bristle tufts 16. The top of the pressure member 32 is profiled to form a complementary brush surface (formed by the front ends of the bristle tufts 16).
  • the bristle tufts 16 are pressed back up in part and are unevenly back against the base member 12 out.
  • a counterpressure part 36 complementary to the pressure part can be provided on this rear side so that the bristle tufts 16 can be axially fixed between the pressure part 32 and counterpressure part 36 as far as possible without play.

  • the receiving opening 50 is open on the side facing the brush holder 44 side. If the bundle taker to the right, based on FIG. 2 , is pivoted, the receiving opening 50 comes in contact with the bristle supply 44. Due to the bias of the bristle supply 44 in the direction of this receiving opening 50, so many bristles press into the receiving opening 50, that it is completely filled.
  • the separation of the bristle tufts 16 thus takes place laterally to the longitudinal extension of the bristles, which in the present case would be perpendicular to the plane of the drawing.
  • the receiving opening 50 When the receiving opening 50 is filled with bristles, it is pivoted clockwise and in the in FIG. 2 shown position moves.

It should be noted that the individual bristle tufts are removed sequentially from the magazine 42 and transported with the tuft picker to their final position before impact. A transfer to subcarrier is avoided here.
  • the base portion 12 has numerous openings 14 which must be successively filled with bristle tufts 16, the base portion 12 is moved in two directions X, Y. In order to be filled openings 14 are aligned with the receiving opening 50 and the next bristle tufts 16 to be injected.
