Definitions

  • the invention relates to a winding machine according to the corresponding preamble of claims 1, 4 and 5.
  • Wing traversing devices are particularly suitable for use at high traversing frequencies. Unlike conventional traversing devices alternating movement of the thread not by one single reciprocating thread guide causes but by the fact that wings rotate in opposite directions take and run the thread alternately. Because the wings neither accelerated at the end points of the traversing area are still delayed, the influence of inertia the thread guide organs completely when reversing the thread switched off.
  • the meeting points are in even Angular distances distributed on the turning circle. The angular distance depends on the number of blades of a rotor. If a rotor e.g. has two wings, it is 90 degrees. If the rotor has three blades, it is 60 degrees.
  • the Location of the polygon formed by the meeting points will depend on the relative phase of the two Rotors off. It is chosen so that two to each other neighboring meeting places near the surface of the Contact roller on a parallel to the axis of the contact roller lying line. These two hangouts are the reversal points of the traversing movement.
  • the wing, each in the section between the reversal points moves the thread. At the end of the section he meets a wing of the other rotor, which gives him the Thread decreases.
  • the traversing device is inclined placed so that between the two levels of rotation on the one hand and the level of the traversing triangle on the other hand - seen in the axial direction of the contact roller - there is an acute angle ⁇ .
  • the traversing triangle is defined by its three corner points.
  • the two Base corner points are the end points of the line in which the Thread runs onto the contact roller.
  • the third corner point is a fixed thread guide element, which in the Practice is usually placed over the winding machine.
  • the level of the traversing triangle defined in this way is correct generally does not exactly match the area covered by the Thread is traversed during the traversing movement. This area is mostly for wing traversing devices curved. Due to the inclination of the traversing device it is achieved that the free thread length between the wing that carries the thread and the one below it arranged contact roller is quite small. The favors the exact placement of the thread on the bobbin.
  • the intersection lines between the plane of the traversing triangle and the two levels of rotation are in known winding machines parallel to the line of contact of the contact roller surface with the traverse triangle, i.e. also parallel to the Contact roller axis.
  • the drag length is included the free length of thread between the wing holding the thread leads to the reversal point and the point where the thread runs onto the contact roller.
  • the one between the tow length difference existing at the reversal points can Operation to a differently good coil structure the two ends of the coil.
  • the two rotors are one
  • the winding unit is mounted eccentrically to one another. This measure serves to guarantee a perfect thread transfer at the ends of the stroke and is for wing changers widespread.
  • the rotor blades neighboring Spooling units are arranged in the same two levels of rotation.
  • the rotors of adjacent winding units are in opposite directions driven and have one in one plane of rotation smaller center distance, one in the other plane of rotation the double eccentricity increased center distance. If three or more winding units are arranged side by side, have the rotors of adjacent winding units, their wings lie in a rotating plane, from winding unit to winding unit alternately a smaller and a double Eccentricity increased center distance.
  • the invention has for its object a winding machine according to the corresponding generic term of To create claims 1, 4 and 5, in which to the Reversal points between the tow lengths existing Difference is smaller than the distance between the two intersection lines in which the plane of rotation the plane of the traversing triangle, and next to each other arranged winding positions correspond geometrically.
  • the direction in which the wings of the lower rotor between the reversal points structural features set in the following described embodiments e.g. through the Arrangement of thread guide edges on the wings and by the direction in which the axis of the upper rotor is offset to the axis of the lower rotor.
  • the mapping between the rotor on the one hand and the turning point at which the Wing of this rotor give up the thread also by others structural features, e.g. through the shape a thread guide or by special organs, that affect the thread transfer at the reversal points.
  • All three variants of the invention are based on the common one Basic idea, the inclined rotating levels next to each other arranged winding units one above the other like scales to lay.
  • the inclination known per se is used in this way according to the invention to several winding units in a row next to each other to accommodate a narrow space, so that between the individual There are only narrow gaps between the traversing areas.
  • that known from the prior art Effect of skewing, namely the approximation of the bilateral drag lengths at least to an essential Part realized.
  • the rise of the cut lines can vary depending on the selected proportions and according to the chosen variant of the invention slightly from differentiate the angle at which the tow lengths both ends of the traversing area are exactly the same.
  • the preferred variant according to claim 1 has the advantage that the wings of all rotors of adjacent winding units in separate rotation levels independently of each other. Collisions that occur in known winding machines e.g. at the Tearing a drive belt of a winding unit and costly machine damage and breakdowns can therefore cause are excluded. Due to the increased distance between the rotating planes conditioned difference in the tow lengths on the two Reversal points is indicated by the slant on a harmless measure.
  • the increased distance between the planes of rotation according to claim 1 offers the advantageous possibility, according to claim 2 Arrange the ruler at each winding point between the rotation levels. This is the distance between the thread guiding Wing and ruler always the same size, regardless of whether one wing of one or the other Rotors leads the thread. This favors the coil build-up.
  • the arrangement according to claim 2 also has the advantage that the organs for fastening and adjusting the ruler are easily accessible.
  • each individual winding unit it is advantageous according to claim 3 with each individual winding unit to equip its own drive. This will do so allows the wings of the individual winding units rotate independently.
  • the drag lengths are almost the same size at all reversal points.
  • the variant according to claim 5 almost combines the advantage equally large drag lengths with the advantage that the Wing of adjacent winding units in separate rotation levels circulate independently.
  • a traversing device 4 for one Thread F which runs vertically from above via a thread guide 5 is also attached to the machine frame.
  • a contact roller 6 is arranged, the axis horizontal and parallel to the axis of the winding spindle 1 is aligned.
  • the traversing device 4 includes two rotors 7, 8, which are rotatably mounted in a housing 9.
  • the Axes of rotation 10, 11 are - such as from DE 93 07 746 U known - parallel to each other at short intervals arranged.
  • the rotors 7, 8 can be driven in opposite directions at the same speed.
  • the rotor 7 has - as can be seen in Figure 2 - three propeller-like arranged blades 13, the rotor 8 has accordingly arranged wings 14. According to FIG. 2, each wing has 13 on the side in the direction of rotation 7a in the front A thread guide edge 13a near its tip. The same applies to the wing 14.

  • the eccentric bush 19 has a bore, the axis 10 to the axis 11 of the Lateral surface is shifted parallel. Is in the hole a shaft 22 of the rotor 7 is mounted.
  • One end of the Shaft 22 projects downward beyond the rotary plane 16 and carries the propeller-like wings 13.
  • On the other end of the shaft 22 is the toothed disk 12.
  • the pair of rotors 7, 8 is supported by a roller 23 from a shaft 24, a first gear 25 and a second gear 26.
  • the shaft 24 is rotatably seated in a Bearing bush 27 which is screwed to the housing 9.
  • the gears 25 connected to the ends of the shaft 24, 26 are the toothed disk 12 and the ring gear 21 assigned.

  • drive belt toothed on both sides wraps alternately, approximately in the form of an S, the toothed disk 12 and that Gear 25 so that the rotors 7, 8 in opposite directions same speed and constant relative phase position are driven.
  • the relative phase position between the two rotors 7, 8 is chosen so that the two meeting points 29, 30 at which the tips of the wings 13 meet the tips of the wings 14, at least approximately in the vertical plane lie, which contains the thread guide 5 and the contact roller 6 touches.
  • This level is the level of the traversing triangle.
  • the two meeting points 29, 30 are the turning points, their distance is the traversing stroke H. Since the illustrated embodiment, the rotors 7, 8 each have three wings, the traversing stroke is approximately the same half the diameter of the circle on which the Move wing tips.

They therefore rise in the direction of the reversal point 29, ie in the direction in which the vanes 13 of the lower rotor 7 move from the reversal point 30 to the reversal point 29 according to arrow 28.
  • the two intersection lines are at a distance d: sina.
  • the drag lengths S (29), S (30) are exactly the same at the two reversal points.
  • the sequence of several winding positions results in angles ⁇ for simple geometric reasons which deviate from the optimal angle ⁇ 0 .
  • the angle ⁇ is smaller than ⁇ 0 , the difference ⁇ S between the drag lengths at the two reversal points 29, 30, which is caused by the distance between the rotational planes 15, 16, is only partially compensated.
  • the angle ⁇ lies between ⁇ 0 and 2 ⁇ 0 , it is overcompensated. In both cases, however, the difference ⁇ S is reduced compared to an arrangement in which the intersection lines of the rotational planes 15, 16 lie horizontally with the plane of the traversing triangle.

  • the distances between two adjacent rotational planes 16E, 15E, 16F, 15F are expediently all of the same size. From simple geometric relationships it follows that the angle ⁇ , which the rotational planes 15E, 16E, 15F, 16F form with the horizontal line 32, is greater in this arrangement than in the previously described exemplary embodiments.
  • Figure 8 also illustrates that the drive belt 35 in one level revolves with the horizontal Base plate 18 also includes an angle ⁇ .
