Definitions

  • the invention relates to a method and an apparatus for producing brushes.
  • 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 present invention relates to a method and apparatus for making brushes based on this AFT method.
  • the invention provides a method and a device that are simple and above all very fast and low maintenance.
  • tufts of bristle stock are removed in succession, that is to say sequentially, and transported to form a base part.
  • This base part may be either a kind of plate, which is then connected to the brush body, or be a portion of the brush body itself.
  • the front side of the base part is the side from which the bristles of the later brush protrude, whereas the back side is the usually closed, that is bristle-free, side.
  • the individual tufts are stuffed into the openings either via a device-side support or holder, which rests against the base part, a guide-free gap between the base part and the device is present in the method according to the invention.
  • the bristle tufts must be pushed through this gap from the device into the base part. A wear on the device can not come about thereby.
  • the position of the base part is aligned with the stationary tool for pushing for each hole to be filled and thus moved.
  • One possibility for this is to move the base part for the sequential piercing at least in two directions, in order to align the opening to be filled with the bristle tufts to be inserted.
  • This method is, as immediately apparent, very easily adaptable to completely new tufts.
  • the method can be adapted very quickly to new patterns if the base part is moved using a freely programmable, at least 2-axis positioning device, in particular a freely programmable, preferably 2-axis industrial robot.
  • the bristle tufts are transported sequentially by a tuft picker to the final position, from which they are pushed axially into the opening to be filled.
  • a tuft picker For the separation of the bristle tufts as well as for the transport, only one movement is required, which can be, for example, a circular arc movement or a linear movement of the tufts collector.
  • the tuft picker does not necessarily have to move back and forth between the pickup position and the dispensing position. It would also be conceivable to provide a ring-shaped or circular tuft picker which rotates permanently in one direction.
  • the bristles used are made of plastic.
  • the back stuffing of the bristle tufts has the advantage that the tufts protrude so far from the base part as far as possible, thanks to a usually front stop, as desired, regardless of the length tolerances of the individual bristles.
  • the bristle tufts is not clamped radially.
  • clamping namely, the tuft end could widen in the gap, which would make it difficult to insert into the openings.
  • Such a radial clamping force will occur in particular in so-called tenter.
  • the gap height measured perpendicularly to the rear side of the base part, should in particular be greater than half the diameter of the bristle tuft; in particular, the gap should be more than twice the cross section of the openings in the base part.
  • the gap exists between the edge of the openings and the transport device, but in particular the gap is even so large that the device is completely spaced from the rear side of the base part.
  • the base part usually has a small thickness and the length of the openings over which the tufts are held, also correspondingly low, provides an advantageous method step, that a guide member is positioned on the device side with through holes before inserting the tufts on the front of the base part ,
  • the bristle tufts are inserted through the openings in the through holes in the guide part.
  • the tufts protrude on the front even out of the guide part.
  • the front ends of the tufts may contact a profiled pressure member during or after loading of the base member to provide a profiled brushing surface.
  • the brush surface is the front side working surface of the brush formed by the bristle ends.
  • This pressure part can either already be present during the plug and serve as a stop or pressed against the bristles after the plug, so that they rest against the pressure part and image the shape of the pressure part.
  • the bristle tufts protruding from the back of the openings of the base part are cut off after being pushed in according to the preferred embodiment.
  • the tolerances of the individual bristle lengths are thereby complete Compensated, because on the front can be done on the pressure part a precise length adjustment, the back is then simply cut off.
  • This cutting can be done by cutting tools or a heated tool, especially a so-called hot knife. There is a contact between the hot tool and the individual tufts, the life of the cutting tool is very high.
  • the bristle tufts are attached on the back, for example by thermal fusion and / or gluing and / or embedding in a molded plastic compound. Of course, these attachment methods can also be combined with each other arbitrarily.
  • the bristles stuffed into the base part are preferably pre-rounded or preprocessed in advance.
  • the tufts are held radially only from the base part and, if present, the guide part. At the two ends no lateral fixation is provided, the ends are only frontally on the device and are thus fixed axially.
  • the back of the bristle tufts and the base part is covered.
  • This can be done, for example, that the brush body has a recess in the region of the back tuft ends, which is closed by a prefabricated or molded lid part.
  • Another possibility of covering the bristle tufts on the back is to form a prefabricated cover part on its side facing the base part with molded-on projections, so-called sacrificial structures, which soften during the subsequent heating, in particular become liquid, in order then to strike against the base part or, more generally to be pressed against the brush body.
  • the brush body can also be provided with such sacrificial structures in order, after its heating, to be connected to the possibly also heated base part.
  • This lid member may be provided with protruding cleaning protrusions in any shape to be used as a tongue cleaner or the like.
  • the base part is overmolded. If the base part is not already at the same time already on the brush body, but a part to be fastened to the rest of the brush body, the base part can be encapsulated during the manufacture of the brush body.
  • elastomeric profile parts which have any cross-sectional shapes, can be injected or injected or fastened in openings. These profile parts are not bristles, but different profile parts with smaller or larger cross-sectional area than the usual bristles.
  • the parts can also have a cross-sectional shape deviating from the circular shape. In particular, such profile parts are used to produce a gum massaging effect.
  • the aforementioned other way to close the tuft-free openings is in the back molding of plastic.
  • either only the tuft-free openings can be closed, or it can front side projecting profile parts are molded with at the same time.
  • the front-side guide part can serve as an injection mold.
  • the bristle tufts are separated from the bristle supply to the side of the bristle longitudinal direction and, in particular, moved individually to the openings via the transport device.
  • no transport tubes known in the prior art are used for the transport device, which dip into the supply in the longitudinal direction of the bristles and receive and clamp a tuft of bristles.
  • high cycle times can be realized by the lateral removal, and on the other hand, the tufts are significantly less or not compressed at all, which improves their positioning when entering the openings.
  • the invention moreover also provides a device for producing brushes, in particular a so-called brush-making machine, which preferably uses the aforementioned method according to the invention.
  • the apparatus comprises a magazine having a bristle stock in which bristles are packed in parallel, a bristle tuft picking unit sequentially picking bristle tufts from the bristle stock laterally to their longitudinal extent, transporting the individual bristle tufts to a stuffing station, the stuffing station comprising a holder for base parts of the brush to be installed, and means, over which the tufts of bristles are sequentially bridged by a guide - free, to the back of the Base part adjacent gap are introduced from the back into the base part and pushed through.
  • the device comprises a closed-loop receiving device, for example a receiving table, a chain, an index table or, more generally, a type of circle with receptacles for the base parts on which they are moved, to individual stations, e.g. to cut through the bristle tufts and attachment of the tufts and optionally closing the back of the open brush body or molding of the brush body.

  • the preferred embodiment provides for integrating a cutting device into the device with which the bristles protruding from the base part on the rear side are cut off.
  • the cutting device is moved transversely to the bristles without any support.
  • the bristles are cut off at the back by acting as a counter knife a device-side support plate through which the tufts protrude. This plate stabilizes the tufts and on the surface of the plate a knife is driven along, which cuts off the tufts.
