Definitions

  • the present invention concerns a method and device for manufacturing brushes.
  • brushes can be made by forming openings in brush bodies, more particularly by boring holes and by subsequently inserting brush fibers in the shape of brush bundles in these openings.
  • the above-mentioned openings can be provided at different angles in the brush body in order to thus insert brush fibers at an angle. This is for example the case when brushes are made whose brush bundles are arranged in the shape of a fan, such as for example scrub brushes, brooms and the like.
  • the distance as of the side of the brush body in which the openings are to be formed to the front side of a drill which is present in the boring tool is not always the same, however, such that, apart from an actual to-and-fro boring movement, also a depth compensation will have to be provided for.
  • the speed and the course of the to-and-fro boring movement can usually not be set, so that the openings will always be drilled with the same speed of penetration and drawback speed.
  • This is disadvantageous in that the boring will not be optimal, and in that for example the rate of speed of the boring is larger than would be optimally required.
  • it is not possible to take the material into account out of which the brush body has been made, nor to reckon with the thickness of the used drill or the like.
  • the present invention aims a method and a device for manufacturing brushes, more particularly for providing openings for brush fibers in a brush body, whereby one or several of the above-mentioned disadvantages are excluded.
  • the invention initially concerns a method for manufacturing brushes whereby openings for bundles of fibers are provided in a brush body, to which end the brush body, while it is placed in a positionable brush body holder, is being presented to a boring tool, whereby this boring tool and the brush body holder are relatively moved to and fro in relation to each other according to the boring direction in order to carry out the boring operation or boring movement, characterized in that the above-mentioned to-and-fro boring operation is realized by means of a single drive element.
  • a single drive element By making use of a single drive element, it is possible to provide the openings without the necessity of using two carriages, several drive elements, multiple cam drives or a slidable brush body holder.
  • the whole is preferably conceived such that the drill head can be placed in several positions as a function of a control, without thereby being bound to certain fixed course lengths. Thanks to the fact that the movement of the boring tool is no longer bound to a fixed course length, the boring tool can be controlled such that not only a depth compensation can be realized, but also the course length can be optimized at the same time as a function of the depth to be bored, such that no unnecessary course is being taken. Moreover, the immediate speed of the boring tool moving to and fro can be adjusted, such that for example the rate of speed and the drawback speed of the to-and-fro boring movement can be optimized.
  • the drive element consists of a controllable positioning motor which is coupled to the carriage, either or not via a transmission.
  • a controllable positioning motor which is coupled to the carriage, either or not via a transmission.
  • Such a motor allows for a very simple control.
  • an electric drive element will be used to this end, such as a servomotor of the rotating or linear type.
  • the invention is particularly useful when manufacturing brushes with rather large brush bodies, whereby a considerable depth compensation has to be provided for, which may strongly vary during the production of one and the same brush.
  • the invention also concerns a device for manufacturing brushes, more particularly according to the above-mentioned method, whereby this device comprises at least a boring device and whereby this boring device in turn at least consists of a positionable brush body holder and a boring tool, whereby a drive device is provided which can relatively move the boring tool and the brush body holder to and fro in relation to each other according to the boring direction so as to carry out a boring operation, and whereby the above-mentioned drive device is formed of a single drive element.
  • FIG. 1 represents a section of a brush which can be realized with a device according to the invention
  • FIGS. 2 and 3 schematically represent a known device in two different positions
  • FIGS. 4 and 5 schematically represent a device according to the invention in two different positions
  • FIG. 6 schematically represents a variant of a device according to the invention.
  • FIG. 1 represents a brush 1 , traditionally consisting of a brush body 2 in which openings 3 have been formed, in which brush fibers 4 in the shape of bundles of fibers 5 have been inserted. At least a number of the openings 3 and bundles of fibers 5 are situated at different angles, as a result of which, as represented, it is possible to realize for example an insertion in the shape of a fan.
  • FIGS. 2 and 3 represent a known boring device 6 with which openings 3 can be formed at different angles in a brush body 2 .
  • This boring device 6 is composed of a positionable brush body holder 7 and a boring tool 8 .
  • the brush body holder 7 is fixed around a point of rotation 9 in a positionable manner, around which it can be positioned by means of a non-represented drive, and thus can be presented to the boring tool 8 in different angular positions.
  • the boring tool 8 comprises a drill head 10 , in which can be provided a drill 11 to form the openings 3 , and a motor 12 to drive the drill head 10 in a rotating manner.
  • the boring tool 8 is provided on a first carriage 13 which can be moved to and fro as such over a fixed course length D 1 in order to realize the actual boring movement, whereas this first carriage 13 is in turn fixed on a second carriage 14 with which can be carried out a depth compensation over a variable distance D 2 .
  • the carriages 13 and 14 are each driven separately by means of the respective drives 15 and 16 which are only represented schematically, whereby at least the drive 15 consists of a cam drive.
  • openings 3 In order to provide openings 3 in a brush body 2 , said brush body 2 is clamped in the brush body holder 7 .
  • openings 3 can be provided at different angles, as is respectively represented in FIGS. 2 and 3 . From these figures it is clear that, as a result of the rotation of the clamped brush body 2 , the point A will be situated more to the right than the point B in FIG. 3 , such that as a function of the place where an opening 3 is formed, a depth compensation has to be provided for, at least when all the openings 3 have to be realized with the same or practically the same depth and/or in order to prevent that the brush body 2 is being bored right through.
  • FIGS. 4 and 5 represent a boring device 17 according to the present invention comprising a positionable brush body holder 18 and a boring tool 19 .
  • the positionable brush body holder 18 can be positioned around a point of rotation 20 and it can be placed in different angular positions in front of the boring tool 19 by means of a schematically represented drive device 21 .
  • the boring tool 19 comprises a drill head 22 which can be driven in a rotating manner by means of a motor 23 .
  • the boring device 17 is special in that only one common drive element 24 is used to realize the to-and-fro movement for the boring as well as to provide for a depth compensation.
  • the drive element 24 can be of any nature whatsoever. Use is preferably made, however, of an electric servomotor of the rotating or linear type, which can enforce a to-and-fro movement to the carriage 25 , possibly via a suitable transmission element, such as a spindle or the like. Instead of a servomotor, use can also be made of other drive elements.
  • control unit 26 controlling the drive element 24 , such that during each boring cycle, a boring movement as well as a suitable depth setting is realized as a function of the position taken by the positionable brush body holder 18 , as is clear from FIGS. 4 and 5 respectively. It is clear that the connection between the angular position and the required depth compensation can be geometrically derived from the arrangement and can be partly determined by means of the required boring results, and that an appropriate control can be realized as such.
  • control unit 26 An additional advantage of this control unit 26 is that the immediate speed of the to-and-fro boring operation can be controlled, such that for example the rate of speed, the speed of penetration and the drawback speed of the boring operation can be optimized. Thus, for example, it is possible to select a slow rate of speed, whereas the speed of penetration can be set higher and the drawback speed even higher still if necessary, in order to speed up the boring operation.
  • FIG. 6 represents a variant whereby only the drill head 22 can be moved, whereas the motor 23 is arranged in a fixed manner.
  • a transmission 27 which allows the drill head 22 to be shifted by means of the carriage 25 , while the rotational movement of the motor 23 can nevertheless be still transmitted to the drill head 22 .
  • a transmission 27 may consist of a geared shaft 28 which can be shifted in the longitudinal direction and which works in conjunction with a gear wheel 29 driven by means of the motor 23 .
  • the invention is not restricted to applications whereby the brush body holder 18 can be positioned around a point of rotation 20 which is formed of a specific axis of rotation.
  • the invention can also be applied to embodiments whereby the brush body holder 18 can carry out other positioning movements, for example around a point of rotation 20 allowing for a rotation in different directions, such as a ball joint, or in a different direction by means of a suspension with several axes of rotation.
  • a boring tool 19 provided on a positionable table, while the brush body holder 18 is either or not arranged in a fixed manner.
  • the drill head 22 is moved to and fro in relation to the brush body holder 18 , it is not excluded to move the brush body holder 18 to and fro in order to carry out the boring operation, while the drill head 22 is arranged in a fixed manner. Also a boring operation which is carried out by moving the brush body holder 18 to and fro, as well as the drill head 22 , is within the bounds of possibility.
  • the method of the invention can be easily derived from the above-described operation of the boring device 17 .
