Definitions

  • the filled bobbins may, for various reasons, be in such condition that they cannot be prepared for unwinding or have not been properly prepared for use by the winder.
  • the bobbins are inspected and bobbins not passing inspection are rejected from the system, and are deposited outside of the system for subsequent manual inspection.
  • This invention relates to a bobbin handling system and, more particularly, to an automatic system having a recirculating portion for handling bobbins and for preventing the system from becoming loaded with bobbins which cannot be effectively handled within the system.
  • bobbin means a body of yarn or an article on which a body of yarn is or may be wound so that the yarn may readily be moved from place to place.
  • filled bobbin means a bobbin whether full or partially full of yarn.
  • yarn is employed in a general sense to apply to all kinds of strand material, either textile or otherwise.
  • the invention in brief, is directed to a bobbin handling system for delivering filled supply bobbins from a spinning or storage area to a winding area, and for returning emptied bobbins from the winding area to the spinning or storage area.
  • the filled bobbins are prepared for receipt by a winder which normally unwinds the yarn from the bobbins and then ejects the unwound bobbins to a sorter.
  • the substantially emptied bobbins are generally returned to the spinning or storage area.
  • Another object is to provide a new and improved bobbin handling system in which partially processed bobbins are recirculated through a portion of the system and bobbins which cannot be effectively processed by the system are rejected therefrom.
  • a related object is provision of such a system in which the rejected bobbins are presented for subsequent inspection.
  • Another related object is provision of such a system in which the rejected bobbins are presented for manual inspection.
  • Still another related object is provision of such a system in which filled bobbins are delivered to the recirculating portion of the system and emptied bobbins are removed therefrom.
  • FIG. 1 is a diagrammatic plan view of a preferred embodiment of the system.
  • FIG. 2 is a fragmentary, schematic, elevational, developed view of a portion of the system with certain parts removed and other parts broken away and in section for clearer illustration.
  • a supply area 10 such as a spinning room contains a plurality of spinning frames (not shown) and loading stations 12 (only one shown in the drawing) which may include storage conveyor bins which deliver filled bobbins to measuring hoppers for subsequent delivery to an overhead conveyor system 16.
  • the overhead conveyor system includes a continuous track 18 which passes through the supply area 10* and a winding area 20 of the mill.
  • This track carries continuously moving containers 22 which receive the filled bobbins from the measuring hopper of the loading station 12.
  • These containers 22 convey the filled bobbins to filled bobbin receiving hoppers 24 (only one being shown in the drawing) in the winding area 20, whereupon the now empty container 22 may receive emptied bobbins from empty bobbin hoppers 28 (only one being shown in the drawing), also in the winding area 20, and deliver these emptied bobbins to a receiving station hopper 30 in the supply area 10.
  • the filled bobbins delivered by suitable conveying means 32 such as a chute, pass through a chute, into bobbin procesing apparatus 34 (as will be more fully discussed later) which is part of a bobbin recirculating portion of the system and includes bobbin preparing apparatus 36 (indicated generally by broken lines) and a winder 38, such as a No. 644 Uniconer automatic winding machine, manufactured by Leesona Corporation, Warwick, RI.
  • the bobbin preparing apparatus 36 prepares the filled bobbins as yarn supply bobbins to be unwound by the winder 38 and the prepared bobbins are transferred by conveying means 40 to the winder, and mOre particularly to winding stations (not shown) of the winder. At the winding stations the filled bobbins are unwound and then ejected by an empty bobbin conveyor of the winder and, as in the previously noted patent application Ser. No. 736,354, now U.S. Pat. No. 3,563,479 are conveyed directly to the empty bobbin hopper 28 for return by the overhead conveyor system 16 to the receiving station hopper 30 in the supply area 10.
  • the overhead conveyor containers 22 and the delivering hoppers 12 and 28- are opened and closed by automatically operating mechanism during transfer of filled and emptied bobbins.
  • the bobbin preparing apparatus 36 includes orienting apparatus 42 which receives randomly jumbled bobbins via the conveying means 32 from the filled bobbin receiving hopper 24, and orients, thereafter delivering the bobbins through suitable conveying means 44 to bobbin readying apparatus 46, to be more fully described later, which is also part of the preparing apparatus. From the readying apparatus 46 the bobbins are delivered by the conveying means 40 and distributed to its winding stations. Upon receiving the filled bobbins the previously noted winder 38 automatically dons, threads unwinds, doffs and then ejects the bobbins.
  • FIG. 2 shows the readier 46 including a rotatable bobbin carrier 48 having a carrier plate 49 fixed to a column 50 journalled, as at 52, on a base plate 54.
  • Suitable indexing apparatus (not shown) is provided for moving the carrier 48 step by step from station to station. The stations are fixedly located relative to the base plate 54.
  • the carrier 48 carries six equally circumferentially spaced vertical chutes 56 for receiving bobbins 57.
  • the chutes 56 are all equidistant from the column 50.
  • Ports 58 in the carrier plate 49 communicate with each of the chutes 56.
  • horizontally swinging gates 60 are mounted on the carrier plate 49 by vertical pivot pins 62. Suitable mechanism (not shown) is provided at certain of the stations for opening the gates when it is desired to discharge a bobbin 57 from the carrier 48.
  • a filled bobbin 57 is delivered, responsive to a signal from control mechanism of the readying apparatus, into the carrier chute 56 and onto the closed gate 60 at the receiving station No. 1.
  • this bobbin is transferred to the reserve station No. 2 and, as disclosed in the reference application, the bobbin 57 is simply held for transfer to the first processing station N0. 3 upon the next indexing of the carrier.
  • the present function of station No. 2 will be discussed later.
  • a tailing end 64 if any, from which winding of a body of yarn 66 on a hollow bobbin core 68 was started, is removed.
  • the bobbin 57 is rotated and an unwinding end 70 of the body of yarn 66 is found by a current of air and transferred thereby through a slot 72 in the chute and a slot 74 in a conduit 76, to a bunch maker 78, at the processing station No. 4, in which the unwinding end 70 is formed into a bunch 79 (note station No. Upon the next indexing of the carrier 48' the bobbin 57 is moved to station No. 4 and an elevating member 80 is moved upwardly into the hollow bobbin core 68 and elevates the bobbin to lift the top of the bobbin core into a mouth 81 of the bunch maker 78.
  • the bunch 79 is now deposited into the interior of the bobbin core 68 whereupon the elevating member 80 is lowered and removed from the core, which is again rested on its gate 60.
  • the bobbin is next moved to the inspection station No. 5 at which a photo-electric system including a photo-electric cell unit 82 is fixed relative to the base plate 54 and directly above the center of hollow bobbin core 68.
  • a reflector 84 is directly below the bobbin core 68 and is mounted for horizontal swinging movement on the base plate 54 by means of a vertical pivot pin 86.
  • the conveying means (chute) 90 from the inspection station No. 5 delivers a bobbin, which has failed to pass inspection, into an inspection bin 92 for subsequent inspection, preferably manual inspection, and the bobbin is thus rejected from the recirculating portion of the system.
  • the reserve station No. 2 is provided with inspection means as described with reference to station No. 5, above, and including a photo-cell unit '82 directly above the bobbin 57 and a swingably mounted reflector 84' directly below the bobbin.
  • the photo-cell unit detects an obstruction, such as cloth or a bunch 79 previously deposited in a bobbin which is being recirculated, the gate 60 and the reflector are swung out of the way and the bobbin is deposited by conveyor means 94, such as a chute, into the bin 92.
  • conveyor means 94 such as a chute
  • an air jet is projected upwardly through the bobbin core 68 to attempt to eject any such foreign matter from the core.
  • This jet is provided through a nozzle 96 opening through the reflector 84' and connected to a suitable source of compressed air by means of a flexible tube 98 so that the nozzle may swing with the gate 60 and the reflector 84' from under the bobbin 57. Operation of the jet is controlled in typical manner by the control system of the readying apparatus.
  • a sorter 100 is provided.
  • This sorter may be of any type known in the art for sorting substantially emptied bobbins from bobbins still containing a substantial amount of yarn. Sorters of this general type are shown in U.S. Pats. Nos. 2,615,556; 2,095,530 and 2,459,309.
  • the bobbins ejected from the winder 3-8 are transferred into the sorter 100 by conveying means 102 which may be of any suitable type such as a chute, belt conveyor or elevator depending on the particular circumstances.
  • the emptied ones of the ejected bobbins are then transferred by suitable conveying means 104 to the empty bobbin hopper 28 for deposit in an empty container 22 of the overhead conveying system 16 and are returned to receiving station hopper 30 in the supply area.
  • the filled bobbins are returned by any suitable conveying means 106 back to the proc essing apparatus 36 and, more particularly, to the orienting apparatus 42, and are thus recirculated through the orienting apparatus, the readier 46 and, if they pass inspection to the winder 38 and the sorter 100.
  • any bobbins which fail to pass inspection are rejected from the recirculating portion of the system and are deposited in the inspection bin 92.
  • An automatic bobbin handling system which recirculates at least some of the bobbins, comprising, processing means for normally unwinding filled bobbins and then ejecting the bobbins, sorting means for receiving the ejected bobbins and sorting substantially emptied ones of the ejected bobbins from ones of the ejected bobbins sufficiently filled to be recirculated to the processing means, means for inspecting the filled bobbins from the sorting means to determine if the bobbins are in condition for processing by the processing means, and conveying means for nonmally recirculating to the processing means the filled bobbins from the sorting means which have been found by the inspecting means to be in condition for processing by the processing means and for diverting from the processing means the bobbins from the sorting means which have been found by the inspecting means not to be in condition for processing by the processing means.
  • a system as set forth in claim 1 including means for returning for rewinding the bobbins found by the sorting means to be substantially emptied, and means for delivering other filled bobbins for processing by the processing means and inspection by the inspecting means.
  • processing means includes means for unwinding the filled bobbins and means for preparing the filled bobbins for use by the unwinding means.
  • a system as set forth in claim 6 in which the inspecting means inspects the bobbins to determine whether or not the bobbins are in condition for receipt by the preparing means and whether or not the bobbins from the preparing means are in condition for receipt by the unwinding means.
  • a system as set forth in claim 9 in which said conveying means rejects from the system the bobbins diverted from the processing means and presents the last said bobbins for manual inspection, means for returning for rewinding the bobbins found by the sorting means to be substantially emptied, and means for delivering other filled bobbins for processing by the processing means and inspection by the inspecting means.
