  • This invention relates to a loading apparatus, and more particularly, to a loading apparatus for automatically loading full bobbins and unloading empty bobbins from a plurality of bobbin carriages arranged to supply conductors to a cable stranding machine.
  • a loading apparatus which comprises a base, an axle rigidly attached to scoop the base, a platform rotatably mounted about the axle, a retractable hydraulic arm, an actuating means including a guide and a linkage, and means for rotating the platform about the axle.
  • the hydraulic arm includes a first section pivotally mounted to the platform and a second section coupled to the first section such that it can be extended or retracted toward the first section. Lifting, lowering, retracting, and extending motions of the hydraulic arm are imparted through the linkage, one end of which is coupled to the second section and the other end is slidably coupled to the guide rigidly mounted on the platform.
  • the rotating means is arranged to rotate the entire platform about the axle and thereby imparts rotary movement to the hydraulic arm.
  • the loading apparatus unloads empty bobbins from the cable stranding machine carriage and replaces them with full bobbins from storage racks parallel to the carriage.
  • the scoop is adapted to scoop up a bobbin and is mounted at a periphery of the platform in such a position that when the loading apparatus is wheeled toward the bobbin the scoop is ready to lift out the latter.
  • the holding bar is attached transverse to the hydraulic arm at its end so that the arm can be maneuvered to bring the holding bar against the bobbin to provide a gripping force.
  • FIG. 1 shows an arrangement according to one embodiment of the invention with the transfer device in one position
  • FIG. 2 shows the arrangement of FIG. 1 with the transfer device in a second position
  • FIG. 3 shows the arrangement of FIG. 1 with the transfer device in a third position
  • FIG. 4 shows an arrangement according to a second embodiment of the invention with the transfer device in a first position
  • FIG. 5 shows the arrangement of FIG. 4 with the transfer device in a second position
  • FIG. 6 shows the arrangement of FIG. 4 with the transfer device in a third position
  • FIG. 7 shows a side view of one transfer device
  • FIG. 8 shows a plan view of the device of FIG. 7.
  • FIGS. 1 to 3 a stranding machine carriage l is shown having ten bobbins A, B, C, D, E, F, G, H, J and K.
  • a storage rack in the form of a stillage 2 contains ten full bobbins I to X, and a bobbin transfer device 3 has two trolleys 4 and 5.
  • the carriage drive is designed so that for loading purposes the carriage 1 can be rotated in known movements to accurately position the bobbins at a known height above the floor level. This operation is carried out automatically in conjunction with the operation of the bobbin transfer device 3.
  • Each bobbin is retained in a cage of the carriage l by means of one fixed and one movable ball bearing pintle.
  • the movable pintle is automatically operated by the bobbin transfer device 3 to open or close the pintle in order to release or retain a bobbin, and has an interlocking arrangement to prevent incorrect example of a bobbin operation.
  • the fixed bobbin ball bearing pintles have braking system to provide, and are controlled by, constant preset tension in the wire during stranding.
  • the bobbin transfer device 3 consists of a powered trolley running in a captive manner between the stillages 2 and the stranding machine and controlled accurately to adopt the required positions.
  • the powered trolley has means for elevating tables to predetermined heights in order to suit the stillages or stranding machine loading heights, and means for adopting predetermined positions along the length of the machine.
  • the tables are provided with means, previously described as trolleys 4 and 5, for removing the bobbins either singly or multiply from the stillage and transferring them to a particular position relative to the carriage in the correct sequence, and also operating the movable pintles. It is also possible to use these arrangements in such a manner that all the empty bobbins are first removed from the carriage, and then full bobbins are loaded into the carriage. In addition, it is also possible that bobbins of two or more adjacent carriages could be unloaded or loaded simultaneously.
  • trolley 4 is shown in Figs. 7 and 8.
  • This trolley is designed to carry two bobbins, and comprises a base 6, with wheels 7, which runs on table 22. Rigidly attached to the base 6 is an axle member 21 supporting a gear which is rigidly attached to it.
  • Platform member 11 is rotatable about axle member 21 on a bush 20, being driven by an electric motor 8 via a gear 9 which intermeshes with gear 10.
  • Attached to the platform member 11, at its end opposite to the electric motor, are two scoops 12 which partially support bobbins 19 during the transfer operation.
  • Pivotably connected in a slot 24 in the middle of platform member 11 is a telescopic hydraulic arm 13 having an extension 16 to which is connected a holding bar 15. Connected to extension 16 is one end of an arm 17, the other end of which is slideably fitted in a slot 18 of a plate 23 which is attached to platform member 1 1.
  • the hydraulic arm 13 In the unoperated state, the hydraulic arm 13 will normally lie in the plane of platform member 11 in slot 24 and extension 16 will be retracted.
  • telescopic arm 13 In the operated state, as the scoops 12 advance towards the bobbins l9, telescopic arm 13 is extended. This causes arm 17 to rise in slot 18, and hence extract extension 16.
  • extension 16 When the scoops 12 are in position adjacent to the bobbins 19, extension 16 is retracted such that holding bar drops down, and lifts the bobbins 19 away from their supports 14 in stillage 2. Bar 15 is then in the positions shown by 15a, and the bobbins 19 are supported in the position indicated by chain dotting by scoops 12 and holding bar 15.
  • the trolley is then moved away from the stillage 2, and the electric motor 8 is actuated to rotate platform member 11 and bobbins 19 through 180.
  • Base member 6 is driven by means, not shown, across table 22, until the bobbins 19 are located adjacent to empty cages of the carriage.
  • Holding bar 15 is then extended, raised, and retracted and the bobbins 19 dropped into the cages, the movable pintles of the cages having been automatically withdrawn when the bobbins were positioned adjacent to the cages, are then extended into the central holes of the bobbins.
  • a loading apparatus comprising: a base; an axle rigidly attached to said base; a platform rotatably mounted about said axle; a retractable hydraulic arm having a first and a second section, said first section being pivotably mounted to said platform, said second section being retractable into and extendible from said first section; load holding and supporting means on said platform and arm; actuating and guide means for extending and retracting said second section from and into said one section, and lifting and lowering said arm about the pivoted end of said arm to engage a load; and means for rotating said platform about said axle to transfer said load from one to another location.
  • said actuating means includes a member rigidly mounted onto said platform guide means on said member proyiding variable osiions between lower and upper limits relative to said plat orm,
  • said load holding and supporting means includes an elongated holding bar rigidly coupled at the tip end of said second section transversely to said arm and scoop rigidly mounted at a peripheral end of said platform.
  • said axle is cylindrically shaped and extends above said base
  • said means for rotating said platform includes a first gear positioned about said axle, a second gear in mesh with said first gear, and a motor rigidly mounted at a periphery of said platform and driving said second gear around said first gear for rotating said platform and load about said axle.
  • An apparatus in accordance with claim 5, further includes a bushing member interposed between said cylindrical axle and said platform.
  • An apparatus in accordance with claim 5, further includes a second scoop and a second hydraulic arm mounted on said platform.
