This means that there is a shoulder or step in the transition between the pressure piece 15 and the adjusting lever 36, 40, so that the adjusting lever 36, 40 eccentrically on the bundle taker 3 due to the centric arrangement of the pressure piece 15 in relation to a transverse extent of the bundle pickup 3 is arranged.
  • the bundle pickup 3 according to FIG. 10 can have a greater material thickness in a section shown below the adjusting lever 36, 40. This promotes the stability of the entire bundle pickup 3.
  • FIG. 10 further shows that the respective adjusting lever 36, 40 is arranged flush with an outer side 43 of the bundle picker 3 oriented transversely to the adjustment direction of the bundle pickup 3. Thus, the adjusting lever 36, 40 is not on the outside 43 of the bundle pickup 3 over.
  • these each have a pocket 34, within which both the pressure piece 15 and the respective adjusting lever 36, 40 are arranged. It can be seen that a depth of these pockets 34 is at least as large as a thickness measured in cross-section of the respective adjusting lever 36, 40. It can be seen in particular from FIGS. 4, 6 and 9 that the front side 5 of the bundle receivers 3 shown there each have an end face 44 or outer contour which is closed except for the bundle removal notch 6. In this way, the bundle strip 3 slides past the bristle supply 4 in the bristle magazine 8 with a homogeneous, uninterrupted and offset-free end face 44.
  • the bristles 10 held within the bristle magazine 8 are thus presented with a smooth and uniform surface except for the bundle removal notch 6.
  • This has the advantage that an undesired bristle distortion or filament delay when feeding the bristle bundles 7 by means of the bundle picker 3 to the stuffing tool 12 of the brush making machine 2 can be avoided.
  • grooves, joints or other misalignment between the moving parts which could affect a reliable and damage-free removal of bristles 10 from the bristle magazine 8, can be avoided.
  • the end face 44 also serves as a barrier between the bristle supply 4 vorhal in the bristle magazine 8 and the movable elements of the bundle pickup third
  • All bundle pickups 3 shown in the figures have a front side 5 which is curved along a circular arc.
  • the bundle takers 3 may also be referred to as a circular-arc pick-up or a circular-arc divider.
  • All of the bundle receivers 3 shown in the figures are pivotable about a pivot axis 45 between the bundle receiving position and the bundle dispensing position.
  • the slide track 29 is arranged on a relative to the front side 5 of the bundle pickup 3 motor-adjustable holder 46.
  • the motor-adjustable holder 46 is guided longitudinally displaceably in a linear guide 47 and can be displaced longitudinally in at least two directions by means of the actuator 48 relative to the front side 5 of the bundle pickup 3.
  • the bristle magazine 8 of the brush-making machine 2 for the bristle stock 4 can be rotated or pivoted relative to a frame 49 of the brush-making machine 2. For example, to fill the bristle magazine 8 easier.
  • the following method of removing a bristle bundle 7 from a bristle stock 4 and transferring the bristle bundle 7 to the stuffing tool 12 of the brush-making machine 2 can be performed. It is provided that the decrease cross section of the bundle removal notch 6 is reduced after filling the bundle removal notch 6 with a bristle bundle 7. As a result, the bristle bundle 7 is held clamped between the pressure piece 15 and a front counterpart 50 of the bundle removal device 1 and the degree of filling of the bundle removal notch 6 is increased.
  • Figure 1 shows that the front counterpart 50 of the bundle picking device 1 is a baffle bent parallel to the front side 5 of the bundle picker 3, extending between an edge of the open side 9 of the bristle magazine 8 and thus between: the bundle receiving position and the bundle dispensing position, and as an abutment surface for the bristle bundle 7 positioned in the bundle removal notch 6.
  • the bundle removal device 1 also has a rear counterpart 51, which has substantially the same construction as the front counterpart 50 and a second open side 52 of FIG Bristle magazine 8 closes, as long as 8 bristles 10 are to be removed len at the first open side 9 of the bristle magazine.
  • the adjusting device 24 is further configured to change the acceptance cross section of the bundle removal notch 6 when filling the bundle removal notch 6 in order to influence the filling behavior. If the bundle taker 3 has reached the bundle delivery position in which the bundle removal notch 6 is located in the stuffing tool 12, the bristle bundle 7 located in the bundle removal notch 6 is ejected from the bundle removal notch 6 by means of the pressure piece 15 and thus transferred to the stuffing tool 12 for further processing.
  • the bundle picking apparatus 1 having the bundle decrease notch 6 variable in its acceptance section, the brush making machine 2 equipped therewith, and the method described above.
  • the bundle removal device 1 it is provided that this has the pressure piece 15, which can be moved between the first edge 16 and the opposite second edge 17 of the bundle removal notch 6 to change the acceptance cross section of the bundle removal notch 6 in this.

Abstract

L'objectif de cette invention est d'apporter des améliorations au domaine des dispositifs de prélèvement de touffes. A cet effet, l'invention concerne un dispositif de prélèvement de touffes (1) comprenant une encoche de prélèvement de touffes (6) présentant une section transversale de prélèvement variable, ainsi qu'une machine de fabrication de brosses (2) équipée de ce dispositif, et un procédé pour prélever des touffes de soies (7) dans un réservoir de soies (4) et les transmettre à une machine de fabrication de brosses (2). Selon l'invention, le dispositif de prélèvement de touffes (1) comprend une pièce d'application de pression (15) qui est disposée entre un premier bord (16) de l'encoche de prélèvement de touffes (6) et un deuxième bord (17) de celle-ci lui étant opposé, de manière à pouvoir être déplacé dans cette encoche sur le dispositif de prélèvement de touffes (1), pour faire varier la section transversale de prélèvement de l'encoche de prélèvement de touffes (6).
