Definitions

  • the present invention relates to a pre-spinning machine with a machine frame and in this at least in one row of spindles and suspended above it, around a common, virtual longitudinal axis of the machine between an operating position and a pull-off position, into which the bobbins are pulled freely upwards out of the spindles can be pivoted wings.
  • Such a leader is z. B. in PCT-Anme avoidance No. WO 81/00264, which belongs to the state of the art within the meaning of Article 54 (3) EPC.
  • the pivotability of the wings of such a roving machine serves to decisively improve the usability of the machine, in particular the pulling and plugging operation of the bobbins. Because the wings can be pivoted away above the spindles, it is then possible to remove the finished bobbins placed on the spindles from the spindles in the vertical direction and also to place new empty sleeves on the spindles in the vertical direction. This simplifies the removal and attachment operation for the personnel if this operation is to be carried out by hand, or makes automation of this operation possible, as is described in detail in the PCT application mentioned.
  • a roving machine of the type mentioned above in that the wings of a row are mounted in a frame which consists of a longitudinal beam and at least two arms perpendicular to this, which are pivotally mounted at their free end in the machine frame about an axis of rotation , and which in the operating position are pressed by means of at least one pivot and loading system containing a spring against a first stop attached to the machine frame, and that the pivoting and loading system is kinematically connected to the frame and to the machine frame in such a way that it is in the operating position of the Frame by passing an unstable position, in which the pressing force has a maximum value, can be brought into a locking position, in which the pressing force is lower.
  • the spindle bank of a roving machine is indicated by 1.
  • the spindle bench 1 carries along a row of spindles 2 arranged at regular intervals, which, in a manner known per se, with not shown be driven.
  • the spindle bench 1 is guided in a manner known per se in the machine frame 3 by means of vertical guides (not shown) and is moved up and down along this with means not shown.
  • wings 5 which, as is known from the above PCT application, around a common, virtual longitudinal axis of the machine between an operating position in which it is coaxial with the rotate corresponding spindles 2, and a withdrawal position in which the coils (only one coil 6 is shown) can be freely pulled upwards out of the spindles 2, are pivotable.
  • the axes 7 of the wings 5 are hollow, so that between the upper part of the longitudinal member 4 and the wings 5 through holes 8 for the known from a drafting system, of which only the delivery rollers 9 and 10 are indicated in FIG. 1 Fuse 11 are provided.
  • the continuous rollers of the drafting system, such as. B. the lower roller 9 are stored in a conventional manner in the machine frame.
  • the longitudinal beam 4 is connected at both ends to an arm 12 or 13, which is perpendicular to it, with which it forms a rigid frame 14.
  • the arms 12 and 13 are pivotally mounted in the machine frame 3 in an axis of rotation 15. 1, the machine frame 3 has a tab 16; but it is clear that the shape of the machine frame 3 can be chosen arbitrarily.
  • the axes 15 of both arms 12 and 13 are coincident and form the virtual longitudinal axis of the machine known per se, about which the wings 5 of a row of wings can be pivoted from the operating position into the pull-off position.
  • each machine frame 3 has a stop 17 for the arm 12 or 13, with which the operating position of the frame 14 and thus the wing 5 is determined.
  • the frame 14 is shown in the operating position, i. H. the arms 12 and 13 are pressed against the stop 17.
  • FIG. 2 in which the roving machine of FIG. 1 is shown from the side in the direction of the arrow R, shows a first variant of the pivoting and loading system 18 for the frame 14.
  • the piston rod 20 of a spring-loaded cylinder-piston system 21 is articulated by means of an axis 19.
  • a preloaded compression spring 23 is contained in the interior of the cylinder 22 and continuously exerts a compressive force on the piston 24.
  • the cylinder 22 is connected at its end opposite the piston rod 20 to the crank 25 of a crankshaft 26 rotatably mounted in the machine frame 3 by means of an axis 27. 2, the operating position of the frame 14 is shown in solid lines, while its retracted pull-off position is shown in broken lines, in which the coils 6 can be pulled off vertically via the spindles 2.
  • F also denotes the curve which describes the center of the axis 19 when the frame 14 is pivoted about the axis of rotation 15. It is an arc with a center in the axis of rotation 15.
  • This solution has the advantage that the torque exerted on the crank 25 in a clockwise direction is not transmitted to the crankshaft 26, but is carried by the machine frame 3 via the stop 29. This allows a welcome relief of the crankshaft 26 in the operating position of the frame 14, which is of particular importance if, as is often the case in practice, the machine has a large number of spindles 2.
  • the machine is divided into individual sections by a few spindles, which are separated by the walls of the machine frame 3: the forces are thus transmitted to the various intermediate walls of the machine frame 3, while the long, continuous crankshaft 26 does not subject to any torsional stress during the time the swing phase is subjected to a much longer operating phase.
  • cylinder-piston system should not be understood here in a pneumatic sense.
  • the cylinder 22 merely forms a straight guide for the piston 24, on which the pressure force of the spring 23 acts.
  • the choice of a closed cylinder 22 as a guide offers only constructive advantages, since the guides, or the piston 24 and the spring 23 in particular, can be shielded well from the external influences (such as flight deposits, etc.); however, other mechanisms with the same function of the cylinder-piston system, such as. B. open guides, thought and realized within the scope of this invention.
  • Fig. 2 the pull-off position of the frame 14 and the corresponding position of the pivoting and loading system 18 are shown with dashed lines: by rotating the crankshaft 26 counterclockwise, the axis 27 of the crank 25 is moved along the arcuate path o, with which the cylinder Piston system 21 moves the axis 19 along the line f clockwise and causes the frame 14 to pivot.
  • the piston 24 in the cylinder 22 is first displaced from the right to the left by the spring 23 up to the stop 28 in the cylinder 22.
  • FIG. 3a to 3d show the pivoting and locking process based on a simplified representation of the lever mechanism described.
  • the frame is not pushed against the stop 17, so that the pressing force P is zero in this position.
  • the spring 23, presses the piston 24 (FIG. 2) of the loading system 18 against the stop 28, with a force that corresponds to the pretension of the spring 23.
  • This position is therefore an unstable position of the system, since from now on the pressing force P can only decrease with a further rotation of the crank 25 in the clockwise direction as well as in the counterclockwise direction.
  • FIG. 3d the operating position of the frame 14, or the arm 12 and the pivoting and loading system 18 is shown.
  • the system has become stable again because the spring force of the spring 23 is now clearly trying to turn the crank 25 clockwise.
  • the position in FIG. 3d is therefore a locking position of the pivoting and loading system 18, since the frame 14 can only be returned from this operating position by passing an unstable position (FIG. 3c) into the pull-off position of FIG. 3a using an external force .
  • FIG. 4 shows a variant of the pivoting and loading system 18 which offers advantages in terms of power engineering.
  • the same elements as in the arrangement of FIGS. 1 and 2 are denoted by the same reference numerals.
  • the difference between this arrangement and that of the previous figures is that here the crank 25 is part of a toothed segment 30.
  • the position of axes 19, 27 and 31 corresponds exactly to that of the variant described above, so that this device works in exactly the same way.
  • the toothed segment 30, which is rotatably mounted about an axis 31 which is fixed in the machine frame (not shown), is rotated in both directions of rotation by means of a toothed pinion 33 which is seated on a longitudinal shaft 32, which is also rotatably mounted in a fixed point of the (not shown) machine frame driven.
  • the longitudinal shaft 32 which preferably extends along the entire machine side, has to transmit a smaller torque for the swiveling process (or in particular for overcoming the unstable position), so that it is lighter in weight can be.
  • this reduction in strength allows the toothed pinion 33 to select relatively soft, but low-noise and low-maintenance materials, such as. B. plastics, and especially if, as shown in Fig. 4, the toothed segment 30 is secured in the operating position against further rotation in the clockwise direction by means of a stop 34 (the function of which corresponds to that of the stop 29 of Fig. 2) .
  • the stop 34 carries the torque exerted by the load system 18 on the toothed segment 30 during the long-term operating position, so that the pinion 33 and the longitudinal shaft 32 are relieved and are only used for the pivoting operation.
  • FIG. 4 further shows that a plate spring assembly 35 can advantageously be used as the spring in the cylinder-piston system 21.
  • This type of spring which is known per se, is very well suited for use in the context of this invention because of its stiff characteristic, since naturally relatively small deflections can be expected here.
  • FIG. 5 shows a variant of the roving machine according to the invention, in which, as is often the case in practice, two parallel rows of wings are provided, each of which is mounted in a pivotable frame.
  • Fig. 5 which shows a schematic representation of the two-row roving machine, seen in the direction of arrow R of Fig. 1, 36 denotes the machine frame in which the two arms 37 and 38 are rotatably mounted in the corresponding pivot axes 39 and 40 are.
  • the arms 37 and 38 each form a frame 43 and 44 with a longitudinal beam 41 and 42 and with an arm not visible, in the longitudinal beam 41 and 42 the wings (not shown) are mounted in rows and driven.
  • both frames 43 and 44 are now connected to one another with a connecting piece 45 such that they always remain parallel to one another, which, for. B. can be achieved, as shown in FIG. 5, that the length of the connecting piece 45 is selected equal to the distance between the pivot axes 39 and 40, in the sense of a parallel guide.
  • FIG. 4 shows how, according to a further preferred embodiment variant of the invention, the first stop 17 determines the operating position of the wings and is designed to be adjustable: a very simple way to achieve the desired adjustability consists in the stop 17 to be designed as a screw 52 which can be screwed into a fixed support 51. The screw 52 is fixed in its position by a lock nut 53.
