Definitions

  • the invention relates to a drive device for the Darning tool of a brush making machine.
  • the tamping tool of a brush manufacturing machine has a guide block with a guide channel for a back and forth tongue that can be moved and a head piece that can be moved back and forth on where the guide channel for the tongue and a of this entrained fiber bundle with anchor plates or Wire loop is continued.
  • the guide block can either be fixed or firmly connected to the head piece or relatively movable to this. In the latter case the leader block is as separate slide executed.
  • the individual fiber bundles are separated from a fiber box by a bundle collector.
  • the fiber bundle is made with anchor plates or wire loops through the tongue into the guide channel of the head piece inserted, which to the surface of the brush body is introduced.
  • the drive for the tamping tool is derived from a rotating drive shaft, sit non-rotatably on the drive cam. On the peripheral surface these drive cams run cam followers, one of which the movement stroke of the tongue and / or the head piece and / or of the guide block is derived.
  • Darning tools of this type see DE 43 24 249 A, US 3 065 469 A or US 1 936 743 A, work at high speed or cycle sequence. You are for a predetermined stroke of the head piece and the tongue designed by those to be manufactured Brushing is determined, especially the length of the Fibers or bristles. While it has already been suggested the working stroke of the tamping tool electrically, pneumatically or to control hydraulically, however, such prove Systems as far too slow and imprecise.
  • the invention provides a drive device for the Darning tool of a brush manufacturing machine available provided a variable and adjustable working stroke of the tamping tool without reducing the working speed and compromise precision.
  • the Invention is in the power transmission path between the Cam follower and the tongue or the head piece an adjusting mechanism inserted through which the movement stroke mechanically is changeable, with at least the tongue and the head piece regardless of the set size of the movement stroke always in the same starting position relative to the guide block to take over a fiber bundle with anchor plates or return wire loop.
  • the adjusting mechanism is a purely mechanical system that Power transmission path lies and the movement stroke only if necessary, an additional stroke is superimposed.
  • the guide block is either fixed be or be firmly coupled to the headpiece and consequently be moved with it or moved relative to the head piece.
  • an adjusting mechanism can be used in a similar way provided between the cam drive and the guide block to mechanically change its stroke can, if necessary.
  • the adjusting mechanism is a pivotally mounted lever provided at one end the cam follower is arranged and its pivot bearing has an adjustable distance from the cam follower.
  • the size of the movement stroke derived from the cam follower now depends on the length of the effective lever, with which the drive of the tamping tool on the pivotable lever connected. Because the pivot bearing of the pivoting lever is adjustable, preferably with the tongue and / or the head piece coupled, movable back and forth Drive rod to the lever at a fixed distance from the Cam follower connected.
  • the adjusting mechanism has a plunger slidably guided back and forth at one end of which the cam follower is arranged; furthermore, the adjusting mechanism comprises one with the tongue and / or the headpiece and / or other parts of the tamping tool (such as the guide block) coupled drive rod and a the mutually facing ends of the plunger and the Linkage connecting rod non-positively.
  • the linkage can be articulated from two at one end interconnected coupling links exist on the other Articulated end on the tappet or on the drive rod are connected. The hinged together The ends of these coupling links are positively guided on a track, their inclination to the direction of movement of the plunger or the drive rod is adjustable changeable.
  • the tamping tool shown in Figure 1 has a known Way a guide block 10, an arcuate bundle pickup 12 with counterpart 14 for the removal of individual Fiber bundles from a fiber box 16 and one at a Slider 18 attached head 20.
  • a guide channel for a tongue 22 is formed in the lead block 10. This guide channel is continued in the head piece 20.
  • the guide block becomes a flat wire from one side 24 supplied, 26 of which by a punch Anchor plates are separated. Alternatively, will Round wire fed, from which wire loops are formed.
  • an adjusting mechanism through which the movement stroke of the tamping tool can be changed within wide limits can without the speed and precision of the To interfere with the darning tool.
  • the adjusting mechanism ensures also that the rear starting position from headpiece and tongue and possibly the guide block are always the same is so that neither the bundle removal nor the feeding of the Flat or round wire from which the anchor plates are separated or wire loops are formed.
  • a first embodiment of this adjusting mechanism is in Figure 3 is shown schematically.
  • a drive cam 30 is rotatably arranged on a rotating drive shaft .
  • a cam follower runs on the peripheral surface of the cam 30 32, which is arranged at one end of a lever 34, the other end pivotable in an adjustable pivot bearing 36 is stored.
  • the pivot bearing is 36 in adjustable in vertical direction.
  • a horizontal, back and forth Movable drive rod 40 to which e.g. the headpiece 20 is connected, carries an arm 40a, which in fixed Distance from the cam follower 32 at 42 pivotable to the lever 34 is connected.
  • the lever 34 is perpendicular to the guide direction the linear guide 38.
  • the movement stroke of the head piece 20 varies. It is straightforward seen that in a similar way with a similar Mechanism of the movement stroke of the tongue and / or the guide block can be varied.
  • On the drive shaft can e.g. several drive cams 30 may be arranged (e.g. 30 'for the tongue and 30' 'for the guide block) with an associated adjusting mechanism for each cam to be able to vary the stroke of each movement.
  • the Actuator mechanism is the cam follower 32 at one end of a horizontally movable plunger 50 arranged. Coaxial with this plunger 50 and at a distance from it is a drive rod 52 also horizontally back and forth slidably arranged.
  • the facing ends of Ram 50 and drive rod 52 are articulated by two connected coupling elements 54 and 56, which at their neighboring Ends are hinged together, non-positively coupled.
  • These ends of the coupling links 54, 56 are forcibly guided in a guide slot 58, which on their the plunger 50 adjacent end pivoted at 60 is.
  • the angle of inclination can be controlled via an actuating rod 62 ⁇ of the guide link 58 can be set.
  • This control device comprises a rotatable with a shaft Cam 70, on the peripheral surface of which a cam follower 72 runs, and a pivotable, two-armed lever 74, on the one end of the cam follower 72 is arranged and the other end is provided with an elongated hole 76, in which engages the end of the actuating rod 62, designated 78.
  • a modulation of the movement stroke of the tamping tool By rotating the cam 70 in this development a modulation of the movement stroke of the tamping tool respectively.
  • An additional way of influencing results from the elongated hole 76 and the displacement of the End 78 of the actuating rod 62 in this slot.
