    [0001] The subject of the present invention is an oscillation device for the wick of a spinning machine according to claim 1.
    [0002] As is known, a spinning machine is capable of processing slivers of roving to make bobbins of thread, after having made an ironing and a twisting on the wick.
    [0003] For this purpose, the spinning machine is constituted by a portal, to which roving coils are hung, which extends along a longitudinal axis.
    [0004] Downstream of the wick coils there is a drafting device, generally formed by three pairs of cylinders having a longitudinal extension, between which the wick passes to be stretched.
    [0005] Downstream of the drafting device, on a base, the spindles are arranged, in a row along the longitudinal axis, rotating around their own vertical axis, to which the stretched and twisted yarn is wound.
    [0006] Usually, the spinning-wheel has two opposing banks, each provided with a row of spindles.
    [0007] The wick, during its travel through the drafting device, would always engage the same restricted area of the cylinders, causing them to wear over time that would be uneven with that (practically non-existent) of the other areas of the cylinders, not affected by the contact with the wick.
    [0008] To avoid this drawback, oscillation devices are known, which operate by performing an axial oscillation of the wick, for example at the entrance to the stretching device, so that the wick is in contact with different areas of the cylinders.
    [0009] However, the currently known embodiments are kinematically rather complex.
    [0010] The object of the present invention is to provide an oscillation device for the wick which overcomes the aforementioned drawbacks with reference to the known art.
    [0011] This object is achieved by a spinning machine comprising an oscillation device made in accordance with claim 1.
    [0012] The characteristics and advantages of the oscillation device according to the present invention will be evident from the description given below, given by way of non-limiting example, in accordance with the attached figures, in which:fig. 1 <SEP> shows an embodiment of a spinning machine, comprising an oscillation device according to the present invention, in accordance with an embodiment;fig. 2 <SEP> represents a diagram of the oscillation device according to the present invention;fig. 3 <SEP> illustrates a diagram of a main group of the oscillation device;fig. 4 <SEP> shows a diagram in side view of the main group of fig. 3;fig. 5 <SEP> represents an axonometric view of the main group according to the present invention, observed from above; isfig. 6 <SEP> shows an axonometric view of the main group according to the present invention, observed from below.
    [0013] A spinning machine according to the present invention extends mainly along a longitudinal axis X and can comprise a support portal for hanging roving bobbins for processing.
    [0014] Furthermore, the spinning machine comprises a drawing device 100 of the wick, consisting of a set of coupled cylinders, arranged longitudinally and adapted to rotate about its own axis. The wick, passing between the cylinders of successive pairs, undergoes an ironing, due to the different rotation speed of the cylinders of the two pairs.
    [0015] Preferably, in a pair of cylinders, the lower cylinder or drawing cylinder is motorized, while the upper cylinder or pressure cylinder is idle and dragged into rotation by the pressure contact with the underlying drawing cylinder.
    [0016] In particular, according to a preferred embodiment of the present invention, each side of the spinning machine comprises:a first pair of cylinders, comprising a first drawing cylinder 1 and the relative first pressure cylinder, immediately upstream of the spindles; the first drawing cylinder can be rotated on command around a first axis of rotation;a second pair of cylinders, comprising a second drawing cylinder 2 and the corresponding second pressure cylinder, immediately upstream of the first pair; the second drawing cylinder can be rotated on command around a second axis of rotation; isa third pair of cylinders, comprising a third drawing cylinder 3 and the relative third pressure cylinder, immediately upstream of the second pair, i.e. immediately downstream of the wick coils; the third drawing cylinder can be rotated on command around a third axis of rotation.
    [0017] Taking into account the two sides forming the spinning machine, this will be provided with two first cylinders 1, two second cylinders 2 and two third cylinders 3.
    [0018] The spinning machine further comprises at least one movement apparatus adapted to rotate on command the drawing cylinders around the respective axes of rotation.
    [0019] According to an embodiment, the spinning machine comprises an head moving apparatus, a tail moving apparatus and an intermediate movement apparatus, for example for the case of a high number of spindles, generally greater than 1200 and about equal to 1800.
    [0020] The first drawing cylinders 1 are interrupted along the longitudinal axis X, preferably in correspondence with the intermediate movement apparatus, so as to define the first sections 1a and second sections 1b.
    [0021] The tail movement apparatus comprises a first first cylinder engine 10, i.e. an electric motor, for moving the first drawing cylinders 1. The first first cylinder engine 10 is kinematically connected to both the first drawing cylinders of the two sides of the spinning machine and moves the first sections of these.
    [0022] The head-moving apparatus also provides a second first-cylinder engine 10 all'est arranged at the longitudinal end opposite to that in which the first first-cylinder engine 10 is arranged. The second first-cylinder engine 10 ́ is kinematically connected to both the first drawing cylinders of the two sides of the spinning machine and moves the second sections 1b of these.
    [0023] The second and third cylinders 2, 3 are interrupted longitudinally in two points: at a separation line S substantially positioned at 1/3 of the total longitudinal length of said cylinders and in correspondence with the intermediate movement apparatus.
    [0024] For the second and third cylinders 2, 3, first, second and third sections 2a, 2b, 2c are thus identified; 3a, 3b, 3c.
    [0025] The tail movement apparatus further comprises a first motor second and third cylinders 20 for moving the second and third stretching cylinders 2, 3. In particular, the first motor second and third cylinders 20 is kinematically connected to both the second cylinders 2 for stretching the two sides of the spinning machine and for both the third cylinders 3 for stretching the two sides of the spinning machine and moving the first sections 2a, 3a of these.
    [0026] Furthermore, the intermediate movement apparatus comprises a second motor second and third cylinders 30 for moving the second and third drawing cylinders, arranged in an intermediate position longitudinally with respect to the longitudinal ends of the drawing cylinders, and moves the seconds sections 2b, 3b and thirds 2c, 3c of said second and third cylinders 2, 3.
    [0027] Each movement apparatus comprises a support structure for supporting the motors of the relative devices for transmitting the rotary motion to the cylinders.
    [0028] The spinning machine further comprises an oscillation device 200 adapted to provide a forced longitudinal oscillation of the roving during the operation of the spinning machine.
    [0029] The oscillation device is moved by the second motor second and third cylinders 30, that is by the motor included in the intermediate movement apparatus.
    [0030] The oscillation device 200 comprises an input shaft 202 having an axis parallel to the longitudinal direction, supported by the supporting structure of the intermediate movement part. The input shaft 202 is rotated by a belt 203, connected to the second and second motor third cylinders 30.
    [0031] Furthermore, the oscillation device 200 comprises a reducer 204, preferably comprising a worm screw, suitable for transforming the incoming rotary motion along a horizontal axis, parallel to the longitudinal axis X, in an outward rotary motion according to a vertical axis V, orthogonal to the horizontal plane.
    [0032] Furthermore, the oscillation device 200 comprises a cam 206 which can be rotated around said vertical axis V and is connected to the output of the reducer 204.
    [0033] Furthermore, the oscillation device 200 comprises a main crosspiece 208, having a prevalent extension along a transverse axis Y, orthogonal to the longitudinal axis X and parallel to the horizontal plane.
    [0034] The main cross member 208 is provided with a connecting element 208a, for example a bearing, engaged with the cam 206.
    [0035] The cam 206 is provided with a bilateral constraint suitable for transforming a continuous rotary motion into an alternating translational motion, ie in an oscillation along the longitudinal axis X.
    [0036] Preferably, said bilateral constraint is constituted by a groove 210, in which said connecting element 208a is inserted, adapted to bidirectionally constrain the translational motion of said connecting element 208a.
    [0037] The main crosspiece 208 extends along the transverse direction Y towards the two sides of the spinning machine.
    [0038] Preferably, said main crosspiece 208 comprises a central portion 212 and side wings 214 which flank the central portion 212 on both sides.
    [0039] Preferably, said lateral wings 214 lie on an imaginary plane substantially parallel to the imaginary plane formed by the axes of rotation of the three stretching cylinders 1, 2, 3, and is therefore parallel to the longitudinal axis and incident to the horizontal plane, to example in descent from the third cylinder 3 towards the first cylinder 1.
    [0040] Furthermore, the oscillation device 200 comprises, on each side of the spinning machine, an oscillation-reducing lever 220, ie a force multiplying lever.
    [0041] Furthermore, the oscillation device 200 comprises a joint element 230, having a longitudinal extension towards the second sections 2b, 3b and towards the third sections 2c, 3c of the second and third cylinders 2, 3; for example, the junction element 230 is made in two parts 230a, 230b, respectively towards the second sections 2b, 3b and towards the third sections 2c, 3c of the second and third cylinders 2, 3.
    [0042] In particular, the lever 220 is hinged in a first application point with the main crosspiece 208 and in a second application point it is hinged to the support structure. Between the two application points, the lever 220 is hinged to the joint element 230.
    [0043] The oscillation of the main cross member 208 is thus transformed into an oscillation, with less amplitude and greater force, of the joint element 230.
    [0044] In particular, the oscillation device comprises an engagement element 216, for example a bearing, fixed to the side wing 214 of the main cross member 208. The position of the engagement element 216 on the lateral wing 214 is adjustable.
    [0045] Moreover, the lever 220 has a seat 222, for example in the form of a slot, in which the engagement element 216 is inserted, to realize the first point of application.
    [0046] Furthermore, the oscillation device 200 comprises a fixing plate 250 for fixing to the support structure, carrying a hinge 252, to which the lever 220 is hinged, to realize the second application point.
    [0047] Finally, the oscillation device 200 comprises a further hinge 260 for the engagement between the lever 220 and the joint element 230.
    [0048] Finally, the oscillation device comprises, on one side and the other of the spinning machine, thread guide rods 270, 280, having a longitudinal extension from the intermediate movement apparatus to the ends of the drawing cylinders.
    [0049] In particular, first wire guide rods 270 extend from the intermediate movement apparatus towards the cylinder ends, overlapping longitudinally with the first sections of the first drawing cylinders 1 and with the first and second sections 2a, 2b; 3a, 3b of the second and third drawing cylinders 2, 3.
    [0050] Furthermore, second thread-guiding rods 280 extend from the intermediate movement apparatus towards the ends of the cylinders, overlapping longitudinally to the second portions 1b of the first drawing cylinders 1 and to the third sections 2c, 3c of the second and third stretching cylinders 2 , 3.
    [0051] The thread-guiding rods 270, 280 are provided with a plurality of yarn-guiding means 290, one for each spinning point, suitable for deflecting the wick during its travel. Preferably, said thread guide means are arranged upstream of the third drawing cylinder 3. For example, said thread guide means comprise a funnel.
    [0052] According to a preferred embodiment, the connection between the joint element 230 and the wire guide rods 270, 280 is adjustable.
    [0053] For example, the connecting element 230 comprises, at the connecting end, a flange 232, to which the thread-guide rod 270, 280 can be fixed, for example by means of screws 234; the flange 232 is sliding and the position can be adjusted by additional screws 236.
    [0054] During the normal operation of the spinning machine, the wick which comes from the roving coils passes into the thread-guiding means and then moves towards the stretching device, in particular towards the third drawing cylinder 3.
    [0055] The second motor, second and third cylinders 30, moves in rotation, through the belt 203, the input shaft 202 and the reducer 204 reduces the rotation speed and transforms the rotary motion along an axis parallel to the longitudinal axis X in a rotary motion along a vertical axis V.
    [0056] The reducer 204 therefore sets the cam 206 in rotation and an oscillating translational motion in the longitudinal direction X is imposed on the connecting element 208a, connected to the cam 206.
    [0057] The oscillatory motion of the connecting element 208a is transferred to the main cross member 208, integral with the connecting element 208a.
    [0058] The oscillatory motion of the main lever 208 is reduced in amplitude and multiplied in force by the lever 220, which moves the thread-guide rods 270, 280.
    [0059] The thread-guiding means of said thread-guide rods 270, 280 are thus equipped with oscillatory translational motion in the longitudinal direction X and displace the sliver being worked on each spinning point with an oscillatory motion in the longitudinal direction X.
    [0060] Innovatively, the oscillation device according to the present invention has a very simple structure and allows to operate from the intermediate movement apparatus towards the head and the tail of the spinning machine.
    [0061] Advantageously, moreover, the oscillation device can be adapted to different spinning machines, since numerous components have an adjustable position according to the occurrence.
    [0062] A person skilled in the art, in order to satisfy contingent needs, could make changes to the oscillation device described above, all contained within the scope of protection as defined by the following claims.
