Definitions

  • the present invention relates to a combing machine according to the preamble of claim 1.
  • Ecartement determines. By definition it is Ecartement that distance between the clamping line of the inner tear-off cylinder and the clamping line of the upper and lower pliers, the moves as close as possible to the vibrating pliers Clamp line of the inner tear-off cylinder results.
  • the size of the ecartement determines the length of the beard, which hangs freely when the pliers are closed and from the round comb is combed. With constant fiber length distribution in The larger the fiber, the more fibers are combed out Ecartement is. This increases the excretion of combs the enlargement of the Ecartementes and decreases accordingly a downsizing of the Ecartementes.
  • Combers are particularly popular in the wool processing industry known that does not follow Nasmith's design template hold (see GB-A-1 207 441) but to the older version by Heilmann.
  • the tear-off movement does not take place through the Swing back the pliers but only by one corresponding movement of the tear-off rollers forward.
  • the forceps bobs up and down in rhythm with the machine rotation.
  • the tear-off cylinders move both rotationally in the rhythm of the machine as well as translationally from back to front and back again.
  • the axis of the shifts per machine cycle Tear-off cylinder once outside and inside again.
  • the Ecartement was set up like the Nasmith machine of the inner reversal point of the tear-off rocker arm.
  • the object of the invention is at the beginning of a combing machine way of making those improvements that are simple and allow rapid adjustment and adjustment of the Ecartementes without necessarily having to stop the machine.
  • the adjustment of the Ecartementes is according to the invention by a independent, joint shifting of all escaping tear-off cylinders reached.
  • the shift can be linear, on a circular arc or on any other convenient curve.
  • the displacement path is relative to the machine movement and the combing process the tear-off cylinder is negligibly small and the Adjustment is independent of the machine cycle.
  • the functions the tear-off cylinders (removal and soldering) continue to be made exclusively through their famous pilgrim-like rotational movement.
  • a pliers head 3 which a circular comb 4 with is assigned to a needle segment 5.
  • the pliers head 3 cooperates Tear-off rollers 6 together.
  • the fiber structure delivered for combing 7 is the pliers head 3 continuously from a winding roll (not shown) fed.
  • the previous one coming out of the pliers The end of the wadding, the so-called fiber beard 10, is with the held between the tear-off rollers 6 and vocational-like regenerated crest 11 soldered and removed from the trailing Cotton 7 torn off.
  • the needle segment 5 is of the from the only freely hanging fiber beard 10 combed combs by a not shown, with higher speed brush roller rotating in the same direction cleaned.
  • the pliers head 3 has an articulated on the pliers axis 2 Lower pliers 13 and upper pliers pivotably mounted on these 14 on.
  • the lower jaw 13 consists essentially of a lower jaw arm 15 and an attached pliers plate 16.
  • the upper pliers 14 can be pivoted stored.
  • the lower tongs 13 there is also a feed roller 18 for the cotton 7 stored, the continuous cotton feed implemented in a discontinuous.
  • the intermittent drive the feed roller 18 takes place in rhythm with the movement of the pliers head by means of a not shown, but in detail in the U.S. Patent 3,479,699 jack transmission.
  • the upper tongs 14 basically consist of one on the pivot pin 17 articulated arm 20 and one attached to it Upper pliers plate 21 and a lever 9 firmly connected thereto.
  • the upper pliers 14 with an adjustable piercing comb 19 provided of those fibers of the fiber beard 10 that are not the The length of the tear-off distance (ecartement) must be one Retracts in the tear-off rollers 6.
  • the top pliers plate 21 is in the rhythm of movement of the pliers head 3 against the pliers plate 16 or swiveled away from it in such a way that the pliers head 3 in the outer (in Fig.
  • end position is open or in the inner end position (in which the pliers plate 16 furthest from the pinch point of the tear-off rollers 6 is closed and the fiber beard 10 is clamped.
  • the Synchronization of the movement of the upper tongs 14 with the movement of the pliers head 3 is carried out by means of a not shown handlebars, the ends of which on the machine stand 1 on the one hand and on on the other hand, lever 9 firmly connected to the upper tong arm 20 are articulated.
  • the tear-off rollers 6 are made up of two pairs of tear-off rollers 6 ', 6 " formed, each a lower, driven and one upper tear roller 23 or 24 has. Your periodic mit-like Forward and backward movement causes in advance (like already mentioned) a removal of the ridge 11 in the direction of Arrow 25 and with the return a soldering with that of the pliers head 3 supplied, combed fiber beard 10.
  • the combing machine is driven by a motor 31 which drives a clock shaft 33 via a reduction gear 32. With the machine pulls in each revolution of the clock shaft 33 Comb game. Also be clock synchronous from the clock wave 33 the lower tear-off rollers 23 via a vocational step gear known per se 37 driven so that its forward and reverse as with the known combing machines during a comb game he follows.
  • the tear-off rollers 6 are rotatably mounted in a bearing block 41 and, as mentioned, driven by the vocational stepper gear 37. Conceivable is also powered by a reversible electric motor.
  • the bearing block 41 is firmly seated on a machine part 61 which a pivot shaft 42 mounted in the machine stand 1, rotatably is connected to a lever 43. Through a shaft 42 pivoting force attack on the lever 43, the tear-off rollers 6 moved against or away from the pliers head 3 and the clamping line 44 of the inner tear-off roller pair 6 ′′ on a circular arc Lane 45 shifted. So the Ecartement E can Clamping line 46 (between lower and upper pliers 13 and 14) of Pliers head 3 can be changed if this is in Fig.
  • Fig. 1 further shows with extended Paint the tear roller 6 in its largest possible Approach to the pliers head 3, in which the Ecartement E, for that the machine is designed is the smallest.
  • the adjustable by a limiting the pivoting path of the shaft 42 or fixed stop can be determined.
  • the adjustment or pivoting the shaft 42 by means of a in the machine stand 1 rotatably mounted threaded spindle 47 generated by Hand or by means of a stepper motor can be driven.
  • Threaded shaft sits on a nut 48 with an axle pin 49 which one end of a link 50 is articulated.
  • the other The handlebar end is articulated on a pivot pin 51 of the lever 43.
  • the threaded spindle 47 and the lever 43 are in the setting of the smallest Ecartementes E parallel and the handlebar 50 is oriented perpendicular to their longitudinal central axes.
  • the nut 48 moves up or below and pivots the shaft 42 by means of the link 50 and of the lever 43 through an angle ⁇ , the tear-off rollers 6 in the position shown in broken lines are moved and the Ecartement E enlarged.
  • the tear-off rollers 6 independent of the other movements to be carried out by them for the removal and soldering of the cotton wool - in its relative position to the fixed points of the pliers head 3 on a circular arc Lane 45 are adjustable with weak curvature, it is possible the path 45 of its adjustment path is even flatter, rectilinear or otherwise designed to be curved. The would be accordingly Bearing bracket 41 on a crank arm (instead of a swivel lever) or in appropriately shaped and attached to the machine stand 1 To store leadership curves. Likewise, the adjustment movement for the tear-off rollers 6 instead of by hand using a stepping motor with an assigned incremental encoder. Are further instead of the reduction shown for the adjustment movement others mechanical reduction gear suitable in the same way.
  • the driven tear-off rollers 23 each sit on one in a rotationally fixed manner in the bearing block 41 freely rotatably mounted shaft 52 or 53.
  • This Shafts 52 and 53 can be rotated further in a on the bearing block 41 attached intermediate gear housing 54 of an intermediate gear 55 stored (Fig. 2).
  • the intermediate gear 55 is the gear Connection from vocational step gear 37 to shafts 52 and 53.
