Definitions

  • This invention relates to a spinning machine comprising means for automatic dofling of bobbins and replacing of the tubes.
  • Spinning machines at present being used require a manual operation for the dofling of the bobbins and replacing of the tubes at the end of winding operation. This operation can also be effected by means of a mechanical device not forming part of the spinning machine. Apparatuses of this type are however, very slow and unreliable, it is often necessary to avail of a number thereof, also because an exact programming of the dofiing in connection with time is not always possible.
  • the automatic spinning machine according to the invention is characterized by comprising as an integral part thereof members for automatically effecting the doffing of the bobbins and replacing of empty tubes; the same being accommodated below the spindle-holders, so that such members will not cause any inconvenience or requiring unnecessary space.
  • the dofiing times can be substantially reduced without significantly stressing the device elements
  • FIG. 1 is a side view of a section of the automatic spinning machine according to the present invention
  • FIG. 2 is a vertical cross-section of the automatic spinning machine of FIG. 1;
  • FIGS. 3-19 diagrammatically show the sequency succession relating to the automatic dotting.
  • FIG. 1 shows the device located on one side of the machine, the device on the other side being similarly formed.
  • FIG. 1 The dofling motion or device is clearly shown in FIG. 1.
  • This device is essentially formed to include an articulated frame comprising a beam or crosspiece 1, shown by full lines at rest position and dashed lines at operative position, said crosspiece carrying the clamping means for the empty tubes 23, and bobbins 24, respectively and two connecting rods 5.
  • Each of the clamping or gripping means may be formed, for example, as a pair of hollow metal cylinders 2 and 3, internally provided with air tubes and inflatable by compressed air (see FIG. 2).
  • crosspiece 1 carries two separate pipes for compressed air 4 and 4', so as to afford an independent control for said clamping means 2 and 3.
  • the connecting rods 5, pivoted at one end of said crosspiece 1, are connected at the other end to sliding blocks 6 and 6 axially slidable on a round bar 7 forming a guide.
  • An endless chain 8, driven by wheel 9, is secured at the top to a sliding block 6', and is slidable with respect to block 6.
  • the lower portion of said chain is secured to sliding block 6, and is slidable with respect to block 6'.
  • the clockwise rotation of wheel 9, driven by a proper speed reducing unit (not shown) carries said sliding blocks 6 and 6 to the positions 6a and 6'a, shown by dashed lines in FIG. 1.
  • Springs 11 and 11' restrained at one end at said sliding blocks 6 and 6' and also slidable on said round bar 7, aid the motor at starting and provide for system motion damping at the end of the stroke thereof.
  • the structure carrying the articulated frame and formed of plates 12, 13 and 14, horizontal crosspieces 15 and 15, and guide 16, acting to said crosspiece 1 in its upward and downward movement is rigid and horizontally translatable. This movement from rest position to a more external position is essential in order that said crosspiece 1 does not interfere with the spindle-holders 17 during its up and down movement, as readily seen from FIG. 2.
  • an electric motor drives three pinions 19 mounted longitudinally of the spinning machine; only one of these pinions is shown in FIG. 2, and a pair of racks 20 and 20 for each pinion, thus obtaining in addition to a horizontal movement an optimum parallelism between said crosspiece 1 and spindles.
  • Racks 20 and 20' mesh at diametrically opposite points with pinion 19 for driving both doifing devices on the sides of said spinning machine.
  • a conveyor belt 21 carries fingers 22, onto which said empty tubes 23 or bobbins 24 are forced (see FIGS. 1 and 2
  • all of the described elements are at their rest condition (which is the condition of normal operation of the machine) under said spindle-holders, whereby no additional obstacles are provided.
  • FIGS. 319 The operation of the device is diagrammatically shown in FIGS. 319, in which for sake of clarity only the position of said empty tubes 23 and bobbins 24 on both sides of said spinning machine and relating to the spinning machine have been shown, without showing the automatic doifing device.
  • a suitable container (not shown in the figure) presents on fingers 22 of conveyor belt 21 the empty tubes to be mounted on spindles 18 after doffing a finger and a tube, corresponding to each spindle and thus each is exactly positioned under the clamping means of crosspiece 1, at the rest position (FIG. 3).
  • the spinning-machine will stop and the ring-holder carriage moves down as loops automatically overturn.
  • FIGS. 12, 13 and 14 A subsequent series of similar movements will allow the positioning of said empty tubes 23 on spindles 18, properly setting them so as to avoid misalignments.
  • By means of compressed air exhaust said cylinders 3 release the clamping of tubes and said crosspiece 1 may thus move upwardly.
  • the subsequent movements, shown in FIGS. 15, 16, 17, 18 and 19, are similar to those described above.
  • Crosspiece 1 moves outwardly and downwardly and deposits bobbins 24 onto fingers 22 of conveyor belt 21 and finally returns to its rest position under the spindle-holders.
  • the spinningmachine can automatically restart and accomplish a new winding operation.
  • the conveyor belt 21 moves the bobbins under a further automatic device (not shown) on the side of the rear shoulder; this provides for unthreading said bobbins from the fingers and storing them within a suitable receiver. Now the belt fingers are free again and ready to receive empty tubes for the next doffing operation.
  • Means for automatically dofiing bobbins and replacing tubes in an automatic spinning machine comprising: an articulated frame, a bearing structure supporting said frame, said bearing structure including a pair of connecting rods, a pair of sliding blocks connected to said connecting rods at first ends thereof, a bar slidably engaging said blocks and guiding the same in substantially rectilinear motion, a crosspiece connected to second ends of said rods, clamping means selectively engaging said bobbins and tubes carried by said crosspiece, movement of said blocks mutually toward and away from each other serving to elevate and lower said crosspiece, in a substantially vertical plane; and means for shifting said frame translationally perpendicular to said vertical plane, andpneumatic means for actuating said clamping means.
