Definitions

  • This invention relates to a machine for loading empty bobbins or support tubes, particularly for continuous filament fibres of nylon, polyester and like type, onto the mandrels of automatic winding machines.
  • the revolver device When a bobbin has been filled with a suitable mass of filament, the revolver device operates automatically in known manner to move another empty tube or bobbin held on a different mandrel into the filament winding zone.
  • An object of the present invention is therefore to provide a machine for automatically loading empty tubes or bobbins onto the mandrels of the winding machine, ie to provide a machine which independently performs said operation without any human intervention.
  • a further object is to provide a machine of the aforesaid type which provides reliable and exact positioning of the empty bobbins on the mandrels.
  • a particular object of the invention (in the case of winding machines with mandrels having spacers between bobbins) is to provide a machine which enables said bobbins to be positioned on the mandrels of such a winding machine so as to create between them a space in order to to free the usual hooking means for said fibres to be wound which are present on said mandrels and enable these means to guide said fibres (at the commencement of winding) onto said bobbins.
  • a further object is to provide a machine of the aforesaid type which is of reliable operation and can advantageously be connected to a known machine (doffer) for doffing the bobbins already wound with synthetic fibre from the winding machine and positioning them on a boat-shaped container or other support.
  • a further object is to provide a machine of low construction cost.
  • a further and advantageous object is to provide a machine of the aforesaid type which enables mandrels pertaining to different groups to be loaded without the need to reach any fixed point from which to withdraw the bobbins or tubes. This enables the time for performing said operation to be reduced.
  • a machine of the aforesaid type characterised in that at least one empty bobbin or tube is mounted on axially mobile transfer means positioned on a transfer unit which is mobile along a first axis and can rotate about a second axis perpendicular to the first so as to move the transfer means into alignment with the mandrel to be loaded, to enable said means to then mount the bobbin or tube onto the aligned mandrel by moving axially.
  • a member acting as a reservoir for a plurality of tubes to be mounted on the winding machine mandrels said reservoir having an internal structure which separates the tubes from each other and is rotatable about a shaft of said reservoir, this latter being provided with at least one lower part for supporting the loaded tubes and provided with a discharge port, the opening and closure of which are controlled and through which the tubes directed towards the transfer unit leave by gravity.
  • Said unit can obviously be fed in any other known manner, including manually.
  • the machine of the invention is indicated overall by 1 and comprises a column 2 to which there are fixed a reservoir 3 for the tubes k to be mounted on mandrels 4 of a usual winding machine 5, and a transfer unit 6.
  • the column 2 comprises an upper flat part 7 to which known drive means 8 are fixed to enable the machine 1 to be driven along an overhead guide 9A and a guide track 9 provided in the plane in which the machine moves.
  • this latter comprises a projection 10 which travels along the track 9.
  • the reservoir 3 comprises a plurality of chambers (only two are shown in Figure 2) for containing the tubes K to be mounted on the mandrels 4 of the winding machine 5.
  • two or more overlying tubes can be disposed in each chamber 11.
  • chambers are provided in a cylindrical casing 12 defining the reservoir 3 and are formed within an internal partition structure 13 (or simply partitions) fixed by spacer arms 14 to a shaft 15 of the casing 12.
  • the partitions 13 are inclined within said casing 12 such that the chambers 11 are of conical shape with their major cross-section facing the top of said casing.
  • top element 16 On said top there is a closure element 16 which is secured to the cylindrical casing in known manner, said top element 16 comprising an aperture 17 to allow the tubes to be introduced into the reservoir 3 in any known manner.
  • the casing 12 is provided with a bottom closure element 18 also fixed to it in any known manner.
  • Said bottom element 18 comprises an aperture or discharge port 19 to allow the tubes K to escape towards the transfer unit 6.
  • the shaft 15 carries at its bottom a gear 20 with which there engages a gear wheel 21 fixed on the output shaft 22 of a geared motor 23 associated with the reservoir 3 in any known manner.
  • the reservoir 3 is supported in known manner by an element 24 associated with a pivot 25 which is fixed to the column 2 by screwing. This enables the reservoir 3 to be easily removed from said column 2 when desired.
  • a lever 26, on which a fork 28 is hinged by a pin 27, is associated with and fixed in any known manner to the pivot 25, which is of fixed construction. On said fork there acts the rod 29 of a pneumatic piston 30, the jacket 31 of which is therefore free to move relative to the lever and in particular to rotate about the pin 27.
  • a device for closing and opening the discharge port 19 is also associated with the bottom closure element 18.
  • This device (shown by dashed lines in Figure 3) comprises a lever 35 pivoted at one end 36 to a projection 37 (visible in Figure 2) of the bottom element 18 of the reservoir 3.
  • the curved opposite end 38 of said lever intercepts the discharge port 19.
  • the lever is driven about the projection 37 by a pneumatic cylinder 40 comprising a rod 41 pivoted at its free end to a substantially central region 42 of the lever 25, and a jacket 43 hinged at its free end 44 to the reservoir 3.
  • the reservoir 3 is also provided with sensor means 47 and 48 fixed rigidly to the casing 12 in any known manner and arranged to sense the presence of the tubes K before their transfer to the unit 6 and their absence after this transfer.
  • a further sensor (not shown), which for example is an optical sensor as are the sensors 47 and 48, senses the presence of the tubes K in the region distant from their transfer.
  • This sensor is advantageously disposed in a fixed position on the column 2 and determines the presence of tubes (or their absence) in the reservoir 3.
  • These sensors can obviously also be used for determining the tubes in the reservoir 3 after this has been loaded.
  • a direct current motor 56 mechanically fixed to the column 2, for example by pins 57 and support plates 58.
  • the motor 56 rotates a shaft 59 on which a pulley 60 is fixed. This latter drives a belt 62 (or similar member) jointly with a reversing pulley 61.
  • Said shaft 59 or drive shaft, is supported via bearings 63 and a flange 66 by a plate 64 positioned over said motor 56 (as can be seen in Figure 1).
  • This plate acts as a cover and comprises a bent part 65 supporting, via bearings 67, one end of the shaft 68 which holds the reversing pulley 61, the other end of said shaft being supported (via bearings 69) by the plate 64.
  • Usual mechanical fixing means 70 (bolts and nuts) support said bearings 67 and 69 and shaft 68.
  • the plate 55 is associated with the belt 62 in known manner. This plate supports the wheels 71 mobile along said guide 51, and is fixed to a structure 72 of the arm 50.
  • a further direct current motor 77 is also connected to the column 2 by a pivot 75 and support plate 76, to drive a shaft 78 on which there are fixed another pulley 79 and a series of different cams 80.
  • the cams 80 cooperate with microswitches 81 supported by a plate 82 fixed to said plate 64.
  • the shaft 78 or drive shaft is supported by bearings 83 at the bent end 65 of the plate 64.
  • a belt (or similar element) 84 secured to the structure 72 of the arm 50 is connected to the pulley 79.
  • This pulley acts as a winch, and when operated rotates said arm about the pin 54.
  • This latter (see in particular Figure 9) is disposed in a suitable seat 87 provided in the arm structure 72.
  • Bearings 88 and 89 are disposed between said parts, mobile relative to each other.
  • an advantageously electromagnetic brake device is positioned at the pin 54.
  • a pusher means (not shown) associated for example with the column 2 or plate 64 is provided to displace the arm from its state of vertical stability.
  • Said device comprises an electrically magnetizable part 90 rigid with the structure 72 of the arm 50, and an insert 91 rigid with the plate 55 with which said structure is associated via the pin 54.
  • the insert 91 subjected to the magnetic field generated by the magnetizable part 90, is associated by bolts, screws or similar members 92 with a member 93 to which said rollers 71 are secured.
  • Tension springs 96 are provided about the bolts or screws 92 to pull the insert 91 towards the member 93 when this is pulled towards the structure 72 by the magnetizable part 90. There is a small clearance between the structure 72 and plate 55 to allow the relative movements between the parts to take place, these movements being opposed by said springs 96.
  • the movements of the arm 50 are controlled respectively by sensors 100, 101 (visible in Figure 1) and by the rotation of the cams 80 in association with the microswitches 81.
  • the sensors 100 and 101 can be moved along a guide 102 to define any required movement of the arm 50 along the column 2, this movement varying according to the arrangement of the mandrels 4 within the winding machine 5.
  • the structure 72 defines a cavity 105 containing a telescopic element 106. This element is arranged to receive the tubes K and to move into a position close to said mandrels 4 before said tubes are transferred onto them. Its position close to the mandrels 4 is shown by dashed lines in Figure 1.
  • the telescopic element 106 comprises (see Figure 8) a first outer fixed cylindrical part 108 and a second part 109 which is mobile within the first, the movement of said part 108 being achieved pneumatically.
  • a cup-shaped element 103 is disposed about the telescopic element 106 to support said part 108 and act as an internal limit stop for the return of the mobile part 109.
  • the rod 110 of a pneumatic piston 111 acts via an articulated joint 112 on said mobile part 109, so preventing any sticking of this latter during its movement, arising for example from any inaccuracy in its fit into the fixed part 108.
  • the tubes K are mounted on the mandrels 4 by a loading device 114 provided with a plurality of deformable hollow elements or fingers 115 which grip the tubes and drag them onto said mandrels. This enables the tubes to be easily positioned on said mandrels 4 independently of any alignment errors between the mandrels and the telescopic element 106. The tubes can thus automatically align with the mandrels, to thus compensate for the small difference between the inner diameter of the tube K and the outer diameter of the mandrel.
  • the fingers are made to grip the tubes by feeding compressed air into them, the gripping force being controlled by a known pressure switch (not shown).
  • the fingers 115 are supported by a structure or carriage 117 comprising a frame 118, in one side of which there is a duct 116 for feeding air into the fingers 115.
  • the carriage 117 is associated with a tubular guide or bar 120 secured by a bracket 121 to a belt 119 (or similar element) driven by pulleys 122 and 123.
  • a belt 119 (or similar element) driven by pulleys 122 and 123.
  • One of these pulleys, the drive pulley 122, is driven by a direct current motor 124 fixed in any manner to the arm 50.
  • the bar 120 supports at least one straight guide 125 mobile on a series of roller supports 126 rigid with a portion 127 of the structure 72.
  • sensors 130 are provided (only one is visible in Figure 7) and can be fixed in different required positions within a guide 131 rigid with said portion 127. Said sensors cooperate with corresponding reference parts 132 which can also be moved in guides 133 and be fixed in suitable positions within them, said guides 133 being associated with said bar 120.
  • a further sensor 135 (see Figures 1 and 6) is disposed at that end 136 of the arm 50 from which the tubes K are mounted onto the mandrels 4 of the winding machine 5.
  • the sensor 135 senses when transfer of said tubes into the winding machine has taken place and stops the machine 1 should this transfer not take place.
  • said sensors, the power feed to the various electric motors with which the machine 1 is provided, and the movement of the pneumatically operated members are all advantageously controlled by a microprocessor circuit which also governs the movement of the machine 1 along the track 9 and its exact positioning in front of the winding machine.
  • the microprocessor also makes it possible to determine the correct positioning on different winding machines of different tubes suitably marked in accordance with the type of product to be wound on the tubes.
  • said reservoir must firstly be provided with tubes K (for example with two or more tubes).
  • the machine 1 is moved into a tube provision region and compressed air is fed to the pneumatic piston 30.
  • the fork 28 As its rod 29 is associated with the fork 28, which is hinged at 27 to the fixed lever 26, feeding air into the piston causes its jacket 31 to move away from the fork 28.
  • the machine 1 is then moved towards the winding machine 5 in which the empty tubes are to be inserted.
  • the movement takes place with the arm 50 axial to the reservoir 3, ie vertical.
  • the arm 50 is rotated and positioned at a height such as to align the telescopic element 106 with the mandrel 4 to be loaded.
  • the rotation which is commenced by the action of the pusher means (such as a spring), continues by gravity, with simultaneous operation by the motor 77 of the pulley 79 which releases the belt 84 until the arm 50 is positioned perpendicular to the column 2.
  • the exact positioning of the arm 50 at 90° to the column is controlled by the cams 80 and the microswitches 81 which operate the electromagnetic brake.
  • the motor 56 is operated. This latter rotates the pulleys 60 and 61 and consequently also the belt 62.
  • the rotation of the arm 50 and its height displacement take place simultaneously.
  • the plate 55 rigid with said belt 61 moves along the guide 51 dragging with it the arm 50 with which said plate is rigid. This movement, controlled by the sensors 100 and 101, terminates when the telescopic element 106 and the mandrel 4 of the winding machine are aligned.
  • the electromagnetic braking device is operated by the cams 80 (and microswitches 81) just before the ara 50 reaches the position perpendicular to the column 2.
  • friction is generated between the insert 91 and the part 90 when the arm 50 is close to its end positions, ie vertical and horizontal.
  • the motor 124 is then operated to move the belt 119 by means of the pulleys 122 and 123, with consequent movement of the bar 120 (and carriage 117) on the supports 126. In this manner the tubes K are mounted on the mandrel 4.
  • Air is also removed from the telescopic element 106 to return the mobile part 109 into the fixed part 108.
  • the movements of the arm 50 (along the column 2 and its rotation about the pin 54) can be achieved by a single motor (for example the motor 77) acting on the pulleys 60 and 79 by gears which are independent but can both be connected by a friction clutch to a single shaft driven by said motor.
  • a single motor for example the motor 77
  • gears which are independent but can both be connected by a friction clutch to a single shaft driven by said motor.
  • the pneumatic circuit which feeds the compressed air-fed members is provided with a pressure switch and a control pressure gauge.
  • the machine according to the invention is associated with a known machine able to unload from the winding machine mandrels 4 those bobbins which have been wound with the continuous filament fibre. This enables the unloading of wound bobbins and the loading of empty bobbins onto other mandrels to be carried out together.
  • the machine can however comprise only the transfer unit 6 without the reservoir 3.
  • the tubes K can be loaded into the unit 6 in another manner, including manually.
  • Said machine can therefore be constructed in various embodiments (for example in which the arm 50 is lowered by pneumatic pistons, a rack and pinion, chains or the like, or in which the discharge port 19 of the reservoir 3 is opened by mechanical members), without leaving the scope of the present invention.
