Definitions

  • the object of the present invention is a spinning frame for obtaining thread reels from rove reels.
  • a spinning frame is capable of processing roving or "rove" reels for obtaining thread reels therefrom, after carrying out a drawing and twisting on the rove.
  • the spinning frame consists of a portal, whereon the rove reels hang, which extends along a longitudinal axis.
  • a drawing device Downstream of the rove reels there is arranged a drawing device, consisting of a set of cylinders having longitudinal extension, wherein between the rove passes to be drawn.
  • the spindles Downstream of the drawing device, on a base, there are arranged the spindles, in a row along the longitudinal axis, rotating about their vertical axis, whereon the drawn and twisted thread is wound.
  • this In order to increase the spinning frame productivity, this usually exhibits two opposite banks, each provided with a row of spindles.
  • the spindles are moved in rotation about the vertical axis by a belt moving device, wherein the belt is moved by an electrical motor and engages spindles of the two banks.
  • the belt of the moving device is often subject to breakage, so replacement thereof is required.
  • the broken belt is easily extracted from the spinning frame, whereas the new belt which makes a single closed annular piece, cannot be mounted or can be mounted with great difficulty and waste of time only, since the presence of the other gears of the spinning frame is an obstacle to the possibility of inserting the belt on the base so as to engage the spindles of the two banks.
  • the object of the present invention is to provide a spinning frame with a belt driven system for spindles which should overcome the disadvantages mentioned with reference to the prior art while meeting the above requirements.
  • FIG. 1 shows a perspective view of a portion of a spinning frame according to the present invention
  • figure 2 shows a perspective view of a further portion of the spinning frame of figure 1 ;
  • FIG. 3 shows a schematic plan view of the spinning frame of figures 1 and 2 ;
  • FIG. 6 shows a schematic plan view of a portion of the spinning frame according to the present invention, in accordance with a further embodiment variation
  • FIG. 7 shows a schematic plan view of a portion of the spinning frame, in accordance with yet a further variation of the present invention.
  • a spinning frame according to the present invention mainly extends along a longitudinal axis X and comprises a support portal for hanging rove reels intended for processing.
  • the portal extends in the top zone of the spinning frame, at a higher height from the support surface T of the machine.
  • the spinning frame comprises a rove drawing device, arranged at an intermediate height, consisting of a set of coupled cylinders, arranged longitudinally and suitable for rotating about their own axis. Passing between the cylinders of a pair, the rove undergoes a drawing, depending on the different speeds of rotation of the coupled cylinders.
  • the spinning frame Arranged in the bottom zone of the machine the spinning frame further comprises a plurality of spindles, arranged in a row along the longitudinal axis X, with vertical axis Z, suitable for rotating about said vertical axis.
  • the spinning frame comprises a first bank 1a comprising a first row 2a of spindles 4a, and a second bank 1b comprising a second row 2b of spindles 4b, the first bank 1 a being spaced from the second bank 1 b along a cross axis T perpendicular to the longitudinal axis X.
  • a working region is thus defined between said banks 1 a, 1 b.
  • the spinning frame comprises at least one electrical motor 6 and a moving belt 8 that forms a closed path lying on a belt plane.
  • the belt 8 is operatively engaged with motor 6 and with a predetermined number of spindles for moving them in rotation.
  • the belt 8 is directly engaged with the motor 6, in the sense that the same belt engaged with the spindles arrives as far as the motor and is driven by it.
  • Motor 6, belt 8 and the spindles engaged therewith form a spindle group.
  • the belt is flat and engages the spindles tangentially, that is, in a direction tangential to the axis of rotation thereof.
  • the spindles are engaged externally to the belt path ( figures 3 , 4 and 5 ), that is, they are arranged tangentially to belt 8, externally to the path formed thereby.
  • the spindles are engaged internally to the belt path ( figure 6 ), that is, they are arranged tangentially to belt 8, internally to the path formed thereby.
  • the spinning frame further has structural obstacles, arranged in the working zone, defining obstacle sections on the belt plane.
  • the drawing device and in particular the cylinders thereof, are supported at the predetermined height by primary columns 10, which rest on the ground surface or on the base structure of the spinning frame, between banks 1a, 1 b, and form structural obstacles; the section of said primary columns with the belt plane defines obstacle sections.
  • the portal for the rove reels is supported at the higher height by secondary columns that rest on the ground surface or on the base structure of the spinning frame, between banks 1 a, 1b, and form structural obstacles; the section of said secondary columns with the belt plane defines further obstacle sections.
  • said obstacle sections are external to the path of the moving belt 8, so as to facilitate the replacement thereof.
  • the belt path defines a closed area and the obstacle sections are external to such closed area, so that the belt is not arranged around the structural obstacles.
  • the spinning frame comprises a pair of deviating pulleys 12, for deviating the belt path starting from the motor.
  • the belt path therefore comprises an active portion 8a, engaged with the spindles, a deviation portion 8b, engaged with motor 6 and comprised between said deviating pulleys 12, and return portions 8c, between the active portion 8a and the deviating portion 8b.
  • the active portion 8a and the return portions 8c extend peripherally to the work zone, that is, so as not to cross it, thus leaving the obstacle sections outside the belt path.
  • the return portions 8c extend parallel to the active portion 8a, that is, they bend thereon, following the pattern thereof, up to reaching the deviating pulleys 12.
  • the active portion 8a of the belt path engages spindles 4a of a single bank 1 a. This occurs when the spindle group is in central position in the bank.
  • the active portion 8a engages spindles 4a, 4b of two banks 1a, 1b ( figure 2 ).
  • the spinning frame comprises spindle groups wherein the spindles are of a single bank and spindle groups wherein the spindles are of two different banks ( figure 3 ).
  • the spinning frame comprises a connection belt 13 and only comprises spindle groups wherein the spindles are of a single bank ( figure 4 ); in said embodiment, a group of a bank is mechanically engaged with a group of the other bank by the connection belt 13.
  • the spinning frame comprises spindle groups wherein the spindles are of a single bank and the spindle groups of a bank are disconnected from the spindle groups of the other bank ( figure 5 ).
  • motor 6 can be positioned along the cross axis T, for stretching the moving belt.
  • the spinning frame comprises a motor plate 22, whereto motor 6 is integral, said plate being shifting along the cross axis T and fixable in a desired position for stretching the moving belt 8.
  • the spinning frame comprises a further electrical motor 14 and a further moving belt 16, operatively engaged with the further motor 14 and with a predetermined number of further spindles for moving them in rotation.
  • the belt 16 is directly engaged with the motor 14, in the sense that the same belt engaged with the spindles arrives as far as the motor and is driven by it.
  • the further motor 14, the further belt 16 and the further spindles form a further spindle group.
  • the further moving belt 16 is preferably arranged on the same plane as the moving belt 8.
  • the spindle group and the further spindle group are mechanically connected for balancing the action of motors 6, 14 on the respective spindles.
  • connection between the spindle groups is made by means of a balancing belt;
  • the spinning frame comprises a balancing pulley 18, engaged with the further belt 16 of the further spindle group, and a balancing belt 20, engaged with motor 6 and with the balancing pulley 18, for mechanically connecting the spindle group to the further spindle group.
  • the balancing belt too forms a closed path external to the structural obstacles, and specifically, external to the obstacle section of the primary 10 or secondary columns.
  • the mechanical connection between different spindle groups, each having the respective motor allows regularising the rotation speed of all of the spinning frame spindles, since transfers of driving torque occur automatically between the connected groups, according to the instant needs of the spinning frame.
  • the balancing pulley 18 can be positioned along the cross axis T, for stretching the further moving belt 16 or the balancing belt 20.
  • the spinning frame comprises a pulley plate 24, whereto pulley 18 is integral, said plate being shifting along the cross axis T and fixable in a desired position for stretching the moving belt 16 or the balancing belt 20.
  • the balancing belt 20 is engaged with motor 6 and with the further motor 14.
  • the spindle group comprises two deviating pulleys 12c, 12d, spaced along the cross axis T ( figure 7 ).
  • the deviating pulley 12d is proximal to the row of spindles, while the pulley 12c is distal to it; specifically the deviating pulley 12d is positioned inside the ideal band defined by the rectilinear sections of the moving belt 8.
  • the straight, active portion 8a of the belt 8, engaged with the spindles 4a, and the straight return portion 8c, are transversely spaced and thus define a band, within which the deviating pulley 12d is positioned close to the spindles.
  • the motor 6 and the balancing pulley 18 are joined to a single motor plate 22.
  • the deviator pulleys 12, 12c, 12d are adjustable in position, transversally or longitudinally, so as to optimise their position depending on the thickness of the belt used.
  • the position of the pulleys is adjustable transversally, that is according to the cross axis T, using a screw adjustment mechanism.
  • the spinning frame according to the present invention allows overcoming the disadvantages of known solutions and meeting the requirements of the field.
  • the spinning frame according to the present invention allows easily and quickly replacing the broken or worn belt with an entire belt, since the entire belt is arranged so as to not enclose the sections of the structural obstacles.
  • the rotation speed of the spindles is regularised by the mechanical engagement between the different spindle groups.
  • Such advantageous aspect also affects the manufacturing inexpensiveness of the spinning frame, as it prevents the use of expensive electronic systems for the speed synchronisation.
  • the spindles are all structurally identical to each other, since they are engaged with the belt at the same points.
  • the belts can be tightened in a simple, correct and effective manner.
  • the position of the pulleys can be adapted to the thickness of the belt used, so as to optimise functioning.
  • the belt is subject to low tensions, if compared with said known devices, and also exhibits smaller dimensions, since the driving torque required is divided among multiple motors.
