Definitions

  • the invention is directed to a combing machine, in particular for combing cotton, with a combing roller provided with at least one comb segment, with feed devices for the fiber beard to be combed and with upper and lower pliers for holding the fiber beard during the engagement of the comb -Segment, upper and / or lower pliers are pivotally mounted forwards and backwards about an axis above the circular crest.
  • a type with such an oscillating pliers arrangement is referred to as the Nasmith type.
  • Such a construction is e.g. B. in the DE-PS 11 61 185 dealt with.
  • the invention is based on the object of designing the drive for the upper and lower pliers in such a way that this is realized with the greatest possible avoidance of reciprocating masses, such movement kinematics should be achievable that with fixedly mounted take-off rollers and a structurally simple one Feeding device can be worked, a high working speed should be achievable by minimizing the moving masses and the synchronization effort with simple construction.
  • This object is achieved in that the drive for the pivoting movement of the upper and / or lower tongs is derived directly from the drive of the combing roller via a cam drive.
  • the cam drive comprises a cam disk and a spring-loaded swivel lever carrying a rotatably mounted feeler wheel.
  • the cam disk is advantageously arranged on the shaft carrying the combing roller. This enables a very compact design to be realized, which enables short and low-loss transmission paths.
  • the free end of the pivoting lever can engage the pliers carrier, which is pivotably mounted about an axis in front of and above the axis of rotation of the combing roller.
  • Such a pivot bearing position is known per se from the prior art.
  • the derivation and transmission of the driving force for the swiveling movement of the collet holder is new.
  • the upper tongs are fastened to an upper tongs carrier, which is pivotably mounted on the lower tongs carrier about a pivot bearing.
  • a guide projection is advantageously connected to the upper tong holder, which is guided via a cam guide.
  • This construction therefore makes it possible to store the take-off rollers in a stationary manner and nevertheless to ensure a secure removal of the fiber beard, with the combing segment being able to engage easily in the combing phase. Due to the provided cam guide of the guide attachment, a very specific relative movement of the upper and lower pliers can be realized while adapting to the special combing task.
  • the guide projection has a guide pin which engages in an arcuate guide groove formed in a guide plate.
  • the guiding plate In order to achieve the desired guiding effect, the guiding plate must naturally be fixed on the machine frame side.
  • the free end of the pivoting lever has an elongated hole extending parallel to its longitudinal axis, into which a guide body of the shaft connected to the pliers carrier engages with longitudinal play.
  • the spring is advantageously designed as a leaf spring and inserted into slots in the upper tong holder or the guide attachment. In this way, the desired spring characteristic can be realized particularly easily.
  • the spring of the cam drive which acts on the lower free end of the pivot lever, is preferably designed as a tension spring, in particular as a coil spring.
  • a feed roller is rotatably mounted on the pliers carrier, that it is connected in a rotationally fixed manner to the feed roller and that at least one gear is arranged concentrically therewith, which meshes with the pivoting movement of the pliers carrier with a fixed, machine frame side fixed tooth segment, and that between the gear and feed roller in a conventional manner, a freewheel is arranged, the freewheeling direction is selected so that the freewheeling effect is effective in the movement opposite to the feed movement of the feed roller.
  • a tooth pawl arrangement or the like can also be used as a freewheel in the broadest sense of the word.
  • the upper tongs 25 'on the upper tong holder 26' is linearly deflectable against the force of springs 65, and that in the region of the pivoting path of the upper tong holder 26 'a cam part 61 with a cam cam 62 is mounted such that a with the upper tongs 25 'connected scanning member 66 of the cam curve 62 abuts and the upper tongs 25' is thereby moved up and down during its pivoting movement.
  • a combing machine shown in the drawing comprises a combing roller 1 with a combing segment 2 with a sawtooth assembly 3, which is only indicated schematically and is known per se from DE-PS 30 07 245, and with a counterweight 4, which is fastened by screws 5 to the base body of the combing roller 1 is.
  • the combing roller 1 is rotatably supported via a combing roller shaft 6 in the side walls 7 and 8 of the combing machine by means of ball bearings 9.
  • a cam disk 10 is seated on the roller shaft 6 and has a radius R that changes progressively between a maximum radius R max and a minimum radius R min .
  • a tension spring 11 which acts on the end 12 of a first lever arm 13 of a pivot lever 16 pivotably mounted about an axis 14 via a ball bearing 15, the cam disk 10 is in contact with a feeler wheel 17, which on the second lever arm 18 of the pivot lever 16 is pivotally mounted about an axis 19.
  • the swivel lever 16 is used in conjunction with the feeler wheel 17 and the cam disk 10 for coordinated with the rotary movement of the combing roller 1 to transmit a drive movement to the pen 1 as described below above the combing roller delnd suspended pliers mechanism.
  • a pliers carrier 23 is mounted above the axis of rotation 20 of the combing roller 1 in the direction of the drawing-off rollers 21 provided in the conventional manner in front of the pliers arrangement about an axis 22.
  • the pliers 24 are fastened to the pliers carrier 23, as can be seen in FIG. 2, and can accordingly execute a pivoting movement about the axis 22, as shown in FIG. 3.
  • An upper tong 25 is attached to the front end 26 of an upper tong holder 27 which is pivotally mounted about U shaft 27 'about a shaft 29 on the lower tong holder 23.
  • the sub-clamp carrier 23 is U-shaped in cross-section, the sub-clamp 23 being fastened in its lateral U-legs 28 and the shaft 29 being pivotally mounted, which has a sliding body extension 30 visible in FIG. 3, which lies outside a leg 28.
  • This sliding body attachment 30 engages in a corresponding longitudinal recess 31 on the second lever section 18 of the pivoting lever 16 in the longitudinal direction with play. Accordingly, a pivoting movement of the pivoting lever 16, in particular the pivoting lever section 18, can be transmitted to the upper tong holder 27.
  • a guide extension 33 is arranged over a shaft 32, which is fixed in its angular position relative to the upper tong holder 27 by a leaf spring 34 which is tangential to the pivot axis 35 of the shaft 32 and accordingly a firm but resilient connection between the guide extension 33 and the Forceps carrier 23 produces.
  • a guide pin 38 which engages in a guide recess 39, is fastened to the free outer end 36 of the guide projection 33 by means of a screw 37.
  • the guide recess 39 is formed in a guide link 41, which is fixedly connected to the machine frame at 40, and extends approximately in a segment of a circle around a center of curvature which lies somewhat below the pivot axis 35.
  • the cam disc 10 bears with its maximum radius R max against the feeler wheel 17 and presses it together with the pivoting lever section 18 into the maximum shown in FIGS. 2 and 3 outer position, being about the Shaft 29 and the guide lug 33 and the guide recess 39 of the upper tong holder 27 can be pivoted with the upper tong 25 relative to the lower tong 24 or the lower tong holder 23.
  • the upper tong holder 27 is pivoted forward and upward about the pivot axis 48 formed by the shaft 29 in the direction of the arrow 49, so that the pliers 24, 25 assume the open position in front of the take-off rollers 21 shown in broken lines in FIG the fiber beard, which was located between the closed tongs 24, 25, and which is not shown in the drawing, is fed to the take-off rollers 21, so that they can have fixed axes of rotation 50, 51 in a particularly advantageous manner and not in turn in synchronism with the combing roller have to be moved towards the pliers assembly.
  • a transport roller 52 is rotatably mounted on the upper tong holder 27 about an axis of rotation 54.
  • the axis of rotation 54 of this transport roller 52 is also shifted accordingly.
  • a gear 55 arranged at the outer end of the transport roller 52 is guided along a toothed segment 56 which is stationary on the machine frame side, as shown in FIG. 3, and is accordingly driven in rotation in the direction of the arrow 57.
  • a freewheel 58 is arranged between the gear 55 and the transport roller 52, which ensures that the transport roller 52 is not driven against the direction of the arrow 57 when the pliers move back into the closed position. In this way, the drive of the transport roller 52, which brings about the further transport of the combed part of the fiber beard, can easily be derived from the rotation of the main shaft 6 of the combing roller 1.
  • a cam part 61 is fastened with screws 60 on both sides of the upper pliers 25 'with a cam curve 62.
  • the upper tongs 25 ' are mounted on an upper tongs carrier 26' in the direction of arrow 63 linearly up and down via linear ball guides 64, coil springs 65 pushing the upper tongs 25 'upward on the upper tongs carrier 26' so that a with the upper tongs 25 ' connected scanning member 66 is pressed against the cam curve 62.
  • the upper tong holder 26 ' is, as described in connection with Figure 1 to 3, pivoted.
  • the upper pliers 25 ' are pressed downward into a closed position via the cam curve 62 when pivoted (to the right in FIG. 4).
  • the top tongs 25 ' is returned to the open position due to the springs 65.
