Definitions

  • the present invention concerns a method and device for rounding off brush fibres.
  • the invention aims a device with which the known rounding off process can be optimized.
  • the invention concerns a device for rounding off brush fibres of the type which consists of a rounding off element which is meant to be put against the ends of the brush fibres and at least one drive element to move the rounding off element in relation to the brush fibres, characterized in that between the drive element and the rounding off element is provided a planetary transmission which, on the one hand, moves the rounding off element around in a circle and, on the other hand, keeps the rounding off element still or almost still as far as the angular displacement is concerned.
  • each point of the rounding off element follows an almost identical and, according to the most preferred embodiment entirely identical path, so that the ends of all brush fibres are subjected to exactly the same polishing movement, and one also obtains that this can be realized with a very compact construction.
  • the planetary transmission has an element functioning as a planet carrier which is driven by means of the drive element, whereas the rounding off element is provided as a planet to the above-mentioned element.
  • the invention concerns a device 1 for rounding off the ends 2 of the brush fibres 3 of a brush 4.
  • the invention concerns a device of the type which consists of a rounding off element 5 which is designed to be put against the ends 2 of the brush fibres 3 and at least one drive element 6, such as en electric motor, to move the rounding off element 5 in relation to the brush fibres 3.
  • Such a rounding off element 5 usually consists of a disc with a grinding face 7.
  • the grinding face 7 can be of different nature. Thus, it can be formed for example in that the top side of the rounding off element 5 is covered with a layer of abrasive material, such as diamond grit and such. According to a variant, the grinding face 7 can also be formed in that the top side of the rounding off element 5 is profiled, for example notched or toothed, whereby this notched or toothed surface is also hardened, or also in that the top side is sandblasted.
  • the invention is special in that between the drive element 6 and the rounding off element 5 is provided a planetary transmission 8 which, on the one hand, moves the rounding off element 5 around in a preferably circular path A and, on the other hand, keeps the rounding off element 5 practically still and preferably entirely still as far as the angular displacement is concerned.
  • figure 1 The thus obtained movement is illustrated in figure 1 by representing the rounding off element 5 in different positions, whereby this rounding off element 5, in order to make it possible to recognize the different positions, is represented in the shape of a polygon, whereby an incision is provided in one side. It is clear, however, that such a rounding off element 5 may actually consist of a disc of any shape whatsoever.
  • the planetary transmission 8 which is represented only very schematically in figure 1, can be composed in different manners in practice. This is illustrated by means of the practical embodiments described hereafter.
  • Figure 2 shows an arrangement in which the rounding off element 5 extends in the horizontal plane.
  • the brush 4 is hereby held above the rounding off element 5 in a brush holder 9 which is provided to this end with the necessary clamps 10.
  • the planetary transmission 8 is provided with an element 11 functioning as a planet carrier which is driven by means of the drive element 6, whereas the rounding off element 5 is provided as a planet to the element 11.
  • the element 11 consists of a cylindrical head which can rotate around a vertical rotary shaft 12.
  • the element 11 is provided in a hollow shaft 14 borne in a frame 13, which is driven in a rotating manner by the drive element 6 via a belt coupling 15.
  • the rounding off element 5 is mounted fixed at the end of a shaft 16 which is borne eccentrically in the element 11.
  • FIG. 2 makes use of a planetary transmission 8 with a fixed sun wheel 17.
  • This sun wheel 17 is mounted to this end on a pivot 18 extending through the hollow shaft 14 which is locked against any rotation at its bottommost end, for example by means of a locking pin 19 which clutches in the frame 13.
  • the shaft 16 is coupled to the sun wheel 17 by means of a transmission 20, which causes a rotation in the shaft 16 which is opposite to the circular movement A and which has a total transmission ratio of 1/1.
  • the transmission 20 consists of a gear wheel transmission.
  • the sun wheel 17 hereby consists of a gear wheel which is coupled via an intermediate gear 21, which can rotate thanks to a shaft 22 provided in the element 11, to a gear wheel 23 which is mounted fixed on the shaft 16.
  • the working of the device 1 of figures 2 and 3 is mainly as follows.
  • the shaft 14 and the element 11 start to rotate. Consequently, the intermediate gear 21 and the gear wheel 23 are moved as planets around the sun wheel 17.
  • the rounding off element 5 does not only make a circular movement, but it constantly remains orientated in the same sense.
  • the transmission 20 does not necessarily need to be a gear wheel transmission and may for example also consist of a belt transmission as represented in figure 4.
  • Figures 5 and 6 show a variant whereby the planetary transmission 8 has a driven sun wheel 17 with which the rounding off element 5 is coupled by means of a transmission 24 whereby, on the one hand, the ratio between the number of revolutions of the element 11 and of the sun wheel 17, and on the other hand the transmission ratio of the transmission 24 is selected such that the rounding off element 5 always stays orientated in the same direction during its movement A.
  • this is obtained in particular by means of a transmission 24 which provides for a rotation between the sun wheel 17 and the rounding off element 5 with a certain transmission ratio, as well as by driving the sun wheel 17 and the element 11 at the appropriate speed.
  • the transmission 24 may consist of a single gear wheel transmission as represented in figure 6.
  • the sun wheel 17 is driven via the in this case rotatable erected pivot 18, which is coupled to a drive element 26 at its lower end.
  • This drive element 26 simultaneously provides for the drive of the element 11 by means of a transmission 27.
  • the speed of the sun wheel 17 can be set in relation to the speed of the element 11 by appropriately selecting the diameters of the pulleys 28-29 and 30-31 used hereby.
  • a same movement can be communicated to rounding off elements 5 of larger sizes by fixing these elements 5 on two or more outgoing shafts 16 of two or more devices as in figure 2 or figure 5, whereby these devices are preferably driven commonly and synchronously.
  • the brush holder 9, the frame 13 and the drive element 6-26 are mounted on frames 32-33-34 which can be fixed or moveable.
  • the mobility can hereby serve to provide for a mutual positioning or to create an additional movement between the brush 4 and the rounding off element 5.
