Definitions

  • the present invention relates to a so-called bristle-dividing element for an apparatus for producing brushes or brooms.
  • Such an apparatus is known from EP 1 493 355 .
  • bristle-dividing element For this purpose associating a so-called bristle-dividing element with each punch is known, such bristle-dividing element, by moving in synchrony with the punch, flexes groups of bristles that have already been inserted into the bristle-holding body to make the hole accessible to the punch, into which hole a subsequent group of bristles has to be inserted.
  • the bristle-dividing element at the end of the insertion operation of a group of bristles into the bristle-holding support, also facilitates extracting of the group of bristles from the punch.
  • the bristle-dividing elements that are known from the state of the art consist of a bar fixed stiffly to an oscillating arm associated with the punch, which moves synchronously with the punch.
  • the present invention aims to provide a bristle-dividing element that is associable with a punch of an apparatus for making brushes or brooms that has a working life that is noticeably greater than that of known prior-art bristle-dividing elements.
  • a bristle-dividing element is provided that is associable with a punch of an apparatus for producing brushes or brooms, said bristle-dividing element being designed to flex groups of bristles already inserted into a bristle-holding body, characterized in that it comprises a supporting arm to an end of which a pivot element is fixed, to which at least one revolving element is mounted so as to be free to rotate.
  • the bristle-dividing element according to the invention interacts with the groups of bristles, the latter slide on at least one revolving element, causing the latter to rotate around the pivot element, thus minimising the friction between the group of bristles and the bristle-dividing element. This makes sure that the wear of the at least one revolving element due to contact thereof with the groups of bristles is also minimised with a consequent sensible increase in the working life of the bristle-dividing element.
  • the at least one revolving element comprises a plurality of revolving elements mounted so as to be free to rotate on the pivot element.
  • This solution has the advantage that it is not necessary, due to wear, replacing the entire set of revolving elements but only those that are most worn, thus reducing replacement costs.
  • Figure 1 there is shown a punch P of an apparatus for producing brushes or brooms, which is suitable for inserting groups of bristles into a bristle-holding body of a brush or of a broom.
  • a bristle-dividing element 1 is associated comprising an arm 2 connected, for example at a first end, to a driving device 3, that is suitable for driving the arm 2, with oscillating motion.
  • a pivot 5 is fixed on which at least one revolving element 6 is mounted so as to be free to rotate, for example roller-shaped.
  • the pivot 5 can be fixed, for example, to a second end 4 of the arm 2.
  • the at least one revolving element 6 is made of material having great resistance to wear, for example hardened steel
  • the at least one revolving element comprises a single roller-shaped revolving element 6.
  • the bristle-dividing element 1 according to the invention is subject to much more gradual wear than the wear of the bristle-dividing elements according to the state of the art. This noticeably increases the working life of the bristle-dividing element 1 according to the invention, in particular in the case of use in making brushes provided with bristles covered with abrasive material.
  • the degree of wear of the bristle-dividing element 1 according to the invention makes it necessary to replace the bristle-dividing element 1, it is not required to replace the entire bristle-dividing element, but only the revolving element 6, with significant cost and time savings.
  • FIG. 3 there is illustrated a second embodiment of the invention, in which on the pivot 5 a plurality of revolving elements 6' is mounted so as to be free to rotate, each roller-shaped, each revolving element 6' thereof being made of a material having great resistance to wear, for example hardened steel.
  • This second embodiment of the invention has the advantage that, as the wear is not uniform on all the revolving elements 6', it is possible to maintain the bristle-dividing element 1 in efficient working condition by replacing only the revolving elements 6' the wear of which has exceed a preset limit, thus reducing the corresponding costs.
  • the worn revolving elements 6' can be replaced rapidly by dismantling the pivot 5 from the arm 2 of the bristle-dividing element 1 and replacing the worn revolving elements 6' with new ones, and then reassembling the pivot 5, with the revolving elements 6' on the arm 2 of the bristle-dividing element 1.
  • the pivot 5 could have an arched shape, or a polygonal shape, the revolving elements 6' being shaped and arranged so as to be free to rotate on the pivot 5.
