  • the first member 166 comprises a movable piston 170 with which an arm 171 is associated. The movement of the movable piston 170 results in movement of the plate 153, further movement of the member 166 (caused by the movement of the piston 168) resulting in additional movement of said plate.
  • Usual antifriction elements (such as bushes, not shown) are provided between the arm 151 and the support 152 to allow relative movement of the parts.
  • a further pneumatic member 175 carried by the plate 153 causes the arm 151 to rotate within the support 152 about its longitudinal axis X.
  • the pneumatic member 175 comprises a sleeve 178 hinged to a pin 180 secured to the plate 153 and a piston 181 associated with the arm 151.

  • the member 162 slides within a sleeve 184 fixed to said plate moved by the member 182.
  • the movement of said plate, of the arm 152 and of the stop member 162 can be achieved by different methods, for example by electric motors.
  • the plate 152 can be moved by a single pneumatic member.
  • the machine 1 is moved by the drive member 20 along the guide 4 until it reaches the winding unit of which said bobbin forms part.
  • the machine 1 being therefore arranged to operate on all said winding units situated in line.
  • the encoder 30 senses the position of the machine 1 along the guide. It should be noted that every movement of the machine and of each of its parts can be remotely controlled by a microprocessor or similar control member which in accordance with a precise procedure controls the operation of each drive member (mechanical, pneumatic or the like used for effecting the movements of said machine and its parts) present on the machine following a request (manual, automatic or programmed) for removing a bobbin 12 from a winding unit.
  • a microprocessor or similar control member which in accordance with a precise procedure controls the operation of each drive member (mechanical, pneumatic or the like used for effecting the movements of said machine and its parts) present on the machine following a request (manual, automatic or programmed) for removing a bobbin 12 from a winding unit.
  • an arm 300 positioned at the bottom of the machine 1 and comprising a member 301 slidable in a guide 302 associated with the winding unit 8 and parallel to the guide 4 allows improved positioning of the machine 1 in front of the winding unit.
  • the drive member 23 moves the carriage 5 into a vertical position such as to enable the support unit 10 to position one of its spindles 37 (that without a tube 11 for example carried by the arm 36) coaxially to the spindle 16 of the winding unit 8 to be unloaded.
  • the movable stop member halts the movement of the spindle 16 by operating a usual switch (not shown) provided on the winding unit 8.
  • the stop member 162 moves for example until it touches the switch on the winding unit.
  • the cutting element 157 acts on the filament to cut it.
  • This filament is sucked in by the suction port 155 and is fed pneumatically into a containing chamber (not shown), for example within the carriage 5, through the duct or tube 156.
  • the arm 65 undergoes simultaneous approach movement.
  • This drive member has the advantage of being compact and allowing considerable movement of the arm 65 in withdrawing from the column 2. It can however be formed in other known ways, for example by pneumatic members or the like.
  • the telescopic elements 70 and 71 extend in the aforesaid manner to achieve approach of the arm 65 to the winding unit.
  • the position attained by said arm is between said bobbin and the winding unit 8.
  • the arm obviously cooperates with that part of the bobbin not wound by the filament.
  • the telescopic elements 70 and 71 partly return into the element 72.
  • This return brings the arm 65 close to the column 2 so as to drag the bobbin 12 onto the spindle 37 of the support unit 10 which, as stated, lies coaxial to the spindle 16 from which the bobbin 12 is extracted.
  • the arm 65 withdraws from this bobbin by rotating about the axis W.
  • Usual proximity sensors determine when the bobbin 12 has been deposited on the spindle 37. Alternatively, this can be determined indirectly by measuring (by any known method) the effort expended by the drive members which move the arm 65 along the axis W (electric motor or pneumatic member), this effort arising when the arm pushes the bobbin 12 onto the spindle 37 after the bobbin has reached its end-of-travel position (for example in contact with the arm 36).
  • the pneumatic pusher 53 is operated to rotate the shaft 40 and hence the arm 39 about the axis K.
  • the arm 65 withdraws from the column 2, dragging with it the empty tube 11, which passes from the spindle 37 to the spindle 16.
  • the arm 65 then rotates about the axis W, separates from the tube 11 and withdraws completely towards the column 2.
  • the movable stop member 162 releases the bobbin stop switch to commence the closure and rotation cycle for the spindle 16.
  • a usual cutting element on the spindle operates on the filament 7 present in its notch, and cuts it to enable the spindle 16 to wind the filament onto a new bobbin.
  • the unit 6 then returns to its initial rest position and the machine 1 withdraws from the winding unit 8 to move the bobbin 12 into a region in which it is unloaded from the spindle 37.
  • an overhead line 500 can be provided (see Figure 1) on which usual trolleys run carrying fixed spindles 501 on which to deposit the bobbin 12 removed from the winding unit (and possibly the empty bobbins 11 to be associated with the machine 1).
  • the carriage 5 of the machine 1 is raised, and in a manner similar to that described for mounting the tube 11 on the winding unit spindle 16 the unit 10 deposits the bobbin 12 on the trolley 501 after withdrawing the empty bobbin to be used for the next cycle.
  • the trolley carries the bobbin to a discharge and storage zone in known manner.
