Definitions

  • the invention relates to a combing machine with a plurality of combing heads, each of which contains a pair of pliers, each with a sub-frame which can be moved back and forth with respect to a machine frame.
  • the lower pliers frames are articulated at their rear ends to pliers arms which are fastened on a pliers shaft common to at least one group of the combing heads, which shaft is pivoted back and forth during operation. If one tries in such a combing machine to increase the number of reciprocating movements of the forceps units per minute - the so-called comb play number - e.g. beyond about 300, it is found that the comb quality in the various combing heads of the machine becomes irregular.
  • the object of the invention is to avoid this deficiency.
  • a combing machine of the type specified at the outset which is characterized by a plurality of cam disks or cranks which can be rotated continuously by a drive shaft, each of the collet frames being coupled in each case to at least one of the cam disks or cranks, in such a way that the pliers frames are moved back and forth by the continuous rotation of the cams or cranks.
  • Each of the cams or cranks is preferably coupled to one of the sub-clamp frames.
  • a cam disc or crank can optionally also be assigned to two adjacent pliers frames.
  • the reciprocating pincer shaft has to transmit relatively large torques to the pincer arms attached to it, around the pincer units to move back and forth, especially of course with high numbers of combs.
  • these large torques to be transmitted not only lead to a high load on the gear parts which swing the reciprocating shaft back and forth, but also to the fact that the collet shaft is twisted along the machine with each reciprocating movement.
  • the various pliers aggregates of the machine are no longer moved back and forth in exactly the same cycle, but phase shifts occur between the back and forth movements of the various pliers aggregates, which in turn result in the irregular combing qualities.
  • the lower pliers frame 1 which carries a pliers plate P, is articulated at its front end on both sides by means of a pin 3 on one arm 4 each.
  • the arms 4 are pivotable about the axis of a shaft 5 which is mounted in the combing machine and is common to several combing heads of the combing machine arranged in a row.
  • the lower jaw frame 1 is articulated on both sides by means of a pin 6 on one arm 7 each.
  • the arms 7 are pivotable about the axis of a shaft 8 parallel to the shaft 5.
  • each pliers unit 1, 2 holds a fiber beard for combing out a circular comb 9 arranged on the continuously rotating shaft 5.
  • the combed fibers are then torn off cylinder 10 taken over.
  • a plurality of cams 12 are provided, which are rotated uniformly by a drive shaft 11 parallel to the shafts 5 and 8, which drive shaft 11 is common to at least one group of the combing heads of the machine.
  • the cam disks 12 can be attached directly to the drive shaft 11.
  • One of the cams 12 is assigned to each of the two arms 7 of each pliers unit 1, 2 (or at least one of these two arms 7).
  • a cam plate 12 can also be jointly assigned to two adjacent pliers 1, 2.
  • On the circumference of the cam disc 12 is a curve follower element carried by the arm 7 in the form of a roller 13.
  • the arm 7 could be subjected to a spring force (not shown) which holds the roller 13 in contact with the circumference of the cam disk 12. However, it is better to guide the arm 7 in a form-fitting manner on the circumference of the cam plate 12 as shown.
  • a lever 14 is attached to the arm 7, which carries a second cam follower roller 15, which also abuts the circumference of the cam plate 12.
  • the two rollers 13 and 15 are preferably arranged approximately diametrically opposite one another with respect to the axis of the drive shaft 11.
  • the circumference of the cam disk 12 is not circular, but is flattened (elliptical) in such a way that the two rollers 13 and 15 rest against this circumference in all rotational positions of the drive shaft 11.
  • lever 14 is preferably fixed on the arm 7 so that tolerances can be compensated.
  • lever 14 may be shown with respect to arm 7 about the axis of the shaft 8 can be pivoted and fastened on the arm 7 with screws 16 which extend through elongated holes 17 in the lever 14.
  • the lever 14 could also be freely pivotable about the axis of the shaft 8 and pulled by a spring (not shown) against the arm 7 or the roller 13 in order to hold both rollers 13 and 15 in contact with the cam disk 12.
  • the front end position of the reciprocating forceps assemblies 1, 2 and thus the so-called ecartement is adjustable.
  • the ecartement is the distance that in the front end position of the pliers 1, 2 the clamping line of the pliers has from the clamping line of the tear-off cylinders 10.
  • the shaft or shafts carrying the cam disks 12, that is to say the drive shaft 11 in FIG. 1 can be arranged so as to be adjustable with respect to the machine frame.
  • the shaft 8, about which the arms 7 can be pivoted, can be arranged so as to be adjustable with respect to the machine frame.
  • the pliers frame 1 is composed of two parts in this way, namely of rear end pieces 1a, which receive the rear pins 6, and of a front main part 1b.
  • the end pieces 1a are adjustable with respect to the main part 1b, so that the distance of the main part 1b from the rear pins 6 can be changed.
  • the front end position of the clamping line of the pliers unit 1, 2 changes, even if the the front end position of the pins 6 moved back and forth by the arms 7 remains the same.
  • the end pieces 1a are fastened to the main part 1b with screws 18 which extend through elongated holes 19 in the end pieces.
  • the drive shaft 11 can carry a plurality of cam disks of different eccentricities arranged axially one behind the other for each arm 7, e.g. three cams 12, 12 'and 12 ⁇ .
  • the cams 12, 12 'and 12 ⁇ are slidable along the axis of the drive shaft 11 so that the cam followers 13 and 15 each abut a selected one of the cams.
  • Each of the three cams 12, l2 'and 12 ⁇ causes a different reciprocation of the arm 7 and thus a different front end position of the pliers unit 1, 2.
  • the cams 12, 12' and 12 ' can sit firmly on the drive shaft 11 and be axially displaceable with this. The cams could also be wedged onto the drive shaft 11.
  • a change in the front end position of the arm 7 and thus the front end position of the pliers unit 1, 2 can, as already mentioned, also be achieved by shifting the axis of the shaft 8 or the axis of the drive shaft 11 with respect to the machine frame.
  • the drive shaft 11 is mounted in links 20 which can be pivoted about the axis of a second drive shaft 11.1 arranged fixed to the frame.
  • the links 20 are fixed to a frame-fixed element (not shown) with screws 22, which extend through elongated holes 23 in the links 20, so that after loosening the screws 22, the links 20 pivot about the axis of the shaft 11.1 and thus the drive shaft 11 can be relocated.
  • the shaft 11 is driven by the shaft 11.1 mounted on the frame from, for example, via meshing gears 24 and 25 on the two shafts 11 and 11.1.
  • Fig. 5 shows the pliers frame 1 of a pair of pliers only in outline.
  • the lower jaw frame 1 is articulated on the arms 4 at the front and arms 7.1 at the rear, which can be pivoted about the axis of the shaft 8.
  • the drive shaft 11 with the cam disks 12 here lies above the shaft 8, between the latter and the lower jaw frame 1, instead of below the shaft as in FIG. 1. This results in a lower overall height and a smaller mass of the arms 7.1.
  • Each arm 7.1 consists of two legs, each of which carries a cam follower roller 13.1 or 15.1 which bears against the circumference of the associated cam plate 12.
  • each combing head carry two cam follower elements interacting with a cam disk
  • FIG. 6 the tongs frame 1 is articulated at the rear on forked arms 7.2, the fork legs of which each carry a cam follower roller 13.2 or 15.2.
  • two cam disks 12.1 and 12.2 are arranged on the drive shaft 11 (one behind the other in the direction of the axis of the shaft 11).
  • One of the cam follower rollers 13.2 and 15.2 carried by the arm 7.2 lies on the circumference of each of the cam disks 12.1 and 12.2.
  • the cam plate 12.2 effects the forward movement of the collet frame 1, while the cam plate 12.1 effects the return movement. Due to the different shape of the two cam plates 12.2 and 12.1, it is possible to freely move the forward and backward movement of the lower jaw frame freely choose.
  • FIGS. 7 and 8 show a similar embodiment as FIG. 6, but the drive shaft 11 - as in FIGS. 2 and 3 - carries several cam disks of different shapes, namely two cam disks 12.1, for each cam follower roller 13.2 and 15.2 and 12.1 'for the cam follower roller 13.2 and two cams 12.2 12.2' for the cam follower roller 15.2.
  • the cam disks 12.1, 12.1 ', 12.2 and 12.2' can be moved along the axis of the drive shaft 11, so that the cam follower roller 13.2 is either on the cam disk 12.1 or on the cam disk 12.1 'and the cam follower roller 15.2 is optionally on the cam disk 12.2 or on the cam disk 12.2 'is present.
  • the collet frame 1 is articulated at the rear on arms 7.3 which are in contact with cam disks 12.3 fastened on the drive shaft 11, preferably as shown in such a way that the cam disks 12.3 have the shape of eccentric circular disks, which are stored in arms 7.3.
  • Ball bearings or other roller bearings can of course be used for the storage of the circular disks 12.3 in the arms 7.3.
  • the arms 7.3 require additional guidance, which is achieved, for example, with a shaft 26 which extends through elongated holes 27 in the arms 7.3.
  • the guide shaft 26 and the elongated holes 27 are below the drive shaft 11, but they could of course also be above the drive shaft 11, between the latter and the collet frame 1.
  • the front end position of the under-clamp frame can, as in all embodiments, be adjustable, for example in that the under-clamp frame 1 is referenced as in FIG. 1 Lich mutually adjustable parts is assembled, or in that the drive shaft 11 is arranged adjustable with respect to the machine frame.
  • the guide shaft 26 is arranged so as to be adjustable with respect to the machine frame.
  • the guide shaft 26 can be attached or mounted eccentrically in circular disks 28 which are rotatably mounted about their axes A in bores fixed to the frame.
  • the additional guidance of the arms 7.3 could instead of the guide shaft 26 and the elongated holes 27 also be effected with other elements, for example with arms (not shown) articulated on the arms 7.3 or on the lower jaw frame 1 (or also on the pivot pin 6) are pivotable about an axis that is stationary during operation.
  • the lower jaw frame 1 is again articulated on arms 7.4, which can be pivoted about the shaft 8.
  • a link 29 is articulated on each of the arms 7.4 and is in contact with a cam disk 12.4 continuously rotated by the drive shaft 11.
  • the cam disk 12.4 is fastened on the drive shaft 11 and has the shape of an eccentric circular disk which is mounted in a bore in the handlebar 29.
  • the articulation point 30 of the handlebar 29 on the arm 7.4 can be adjustable with respect to the arm. With an adjustment of the articulation point 30 in the longitudinal direction of the arm 7.4, a change in the path ratio, i.e. a change in the amplitude of the back and forth movement of the crimping frame 1 can be achieved. With an adjustment of the articulation point 30 transversely to the longitudinal direction of the arm 7.4, the front end position of the lower jaw frame 1 can be adjusted.
  • crank pins carried on crank arms Such a variant for the embodiment according to FIG. 10 is shown in FIG. 11. 11, a link 29.1 is articulated on the arm 7.4, in which a crank pin 31 is mounted. The crank pin 31 is carried on a crank arm 32 which sits on a shaft 11.2 and is rotated continuously by the latter.
  • the shaft 11.2 could be a drive shaft common to several combing heads of a combing machine. In this case, the shaft 11.2 would be a cranked crankshaft that was cranked several times.
  • the shaft 11.2 can also be shorter and only carry one or two crank arms 32 of a combing head and, for example, gears 33 and 34 can be rotated by a continuous drive shaft 11.3 common to several combing heads. (Each combing head would have one or two separate shafts 11.2 with one or two crank arms 32 each.)
  • a collet frame 1.1 is articulated at the rear on arms 7.5, which are in contact with cam disks 12.5 fastened on the drive shaft 11, for example in that the cam disks 12.5, in the form of eccentric circular disks, are mounted in bores in the arms 7.5, similarly to in Fig. 9.
  • the crimping frame 1.1 is rigidly connected at its front end with arms 4.1, which are pivotally mounted about the axis of the shaft 5. Because of the rigid connection of the collet frame 1.1 with the arms 4.1, the arms 7.5 in this embodiment do not require any additional guidance.
  • FIG. 13 shows an embodiment in which a cam disk 12.6 continuously rotated by the drive shaft 11 is in direct contact with a collet frame 1.2 stands to move it back and forth.
  • the cam plate 12.6 can again, for example, have the shape of an eccentric circular disk and be mounted in the rear part of the collet frame 1.2, which can then be articulated at the front to the arms 4 pivotable about the axis of the shaft 5.
  • the lower jaw frame 1.2 could, however, also be guided so that it can move back and forth in another way and be in contact with the cam disc, for example via one or two cam follower elements carried by the lower jaw frame.
  • FIGS. 12 and 13 the eccentric circular disks 12.5 and 12.6 shown could be replaced by crank pins carried on crank arms, corresponding to FIG. 11.
  • the crank pin would be supported in arm 7.5, while in FIG Pliers frame 1.2 would be stored.
