  • FIG. 14 is a fragmentary view of the electrical connections controlled by a bobbin peg actuated switch and including a solenoid for imparting a step advanced movement to the bobbin magazine.
  • the magazine 20 is formed with a circular series of vertical containers or cans 26, each adapted to hold a replenishment bobbin or cop 28 and to be brought into operating relation to the supply holder of a succeeding winding unit in succession by the relative movement between the magazine and the several units.
  • a bottom plate 30 of the magazine 20 rests upon a continuously driven rotating friction collar 32. Movement of the magazine is controlled by stop devices which when disengaged permit movement of the magazine in a counter-clockwise direction with the friction collar 32.
  • a series of stop pegs 33 on a horizontally disposed structural disc 34 of the magazine are adapted to be successively intercepted by the lowered armature 35 of a solenoid 36. A momentary energizing of the solenoid raises the armature 35, releases the magazine, and allows it to turn through the angle represented by one can 25, whereupon the next stop peg 33 is caught by the lowered armature 35.
  • the elevating conveyor 42 is driven by means of an electric motor 54 which is installed below the horizontal conveyor and drives a speed reduction mechanism 56 by means of a V-belt.
  • a clutch driving element not shown, loosely mounted on a clutch shaft 66 is continuously driven from the speed reduction mechanism 56.
  • the shaft 66 is arranged to be driven through one revolution by means of clutch connection which include a solenoid Sol, 3.
  • This mechanism is identical with that hereinafter more fully described for driving the piece bobbin elevating conveyor, and is, therefore, not further described.
  • the sprockets 48 are fixed to a sprocket shaft 70 and rotate together with a ratchet wheel 72 which is also fixed to the same shaft 70, and which is driven by a pawl 74.
  • the pawl '74 is driven by the clutch shaft 66 through a known type of linkage.
  • the bobbins 2S supplied along the chute plate 40 are picked up one by one and conveyed by the slats 46.
  • the clutch shaft 66 rotates through one revolution, its motion is transmitted through the above said linkage, the pawl 74, the ratchet wheel '72, the sprockets 48, and chain 44 to advance the slats 46 by one pitch, that is, the spacing of the slats, whereby one bobbin only at a time is caused to drop from the upper part of the conveyor, under the guidance of a guide plate 76, into an elevating conveyor chute 78.
  • One of the side members of the chute 78 is defined by an inclined and curved surface as shown in FIG. 2 by means of which the bobbin 28 in the chute is displaced from a horizontal to a vertical position thus guiding the bobbin into the aligned magazine can 26.
  • Mechanism is provided also as hereinafter more fully set forth for controlling the operation of the full bobbin elevating conveyor and the piece bobbin conveyor so that the operation of the one is temporarily suspended when a piece bobbin is delivered to the magazine to insure a smooth and uninterrupted operation of the magazine feed.
  • the used bobbins 82 are detected by means of a dofiing apparatus and are ejected from the discharge station of the travelling winder which is Well known, and is set forth for example in the Abbott et al. Patent 2,177,763.
  • the chute 81 associated with the dofiing apparatus is shaped to cause the discarded bobbins 82 to be deposited onto the inclined conveyor 84, small end first.
  • the conveyor 84- consists of an endless belt supported to turn on suitable rolls 9t: and 98 and at its upper end abuts the second transversely disposed conveyor 86.
  • the inclined conveyor 84 is continuously driven by a motor 169 and reduction gear unit 31b2, which is connected to drive the roll 96.
  • the transverse conveyor 86 similarly comprises an endless belt supported to turn on the spaced apart rolls 184, 196, and is continuously driven by a motor 108 and reduction gear unit 116 connected with the roll 104.
  • the conveyors 84 and 86 are fenced in along both sides by side walls 112 shaped to guide the used bobbins along the conveyor 84 and around onto the conveyor 86.
  • the used bobbins are now passed through the sorting unit 83 shown in detail in FIGS. 4 to 8 inclusive.
  • This unit comprises a housing, within which are provided a sensing device to distinguish those bobbins having usable amounts of yarn left thereon from others having little or no yarn thereon to be classed as rejects, and a pair of compressed air nozzles which are employed to blow reect bobbins from the conveyor into a suitable receptacle 114 (see FIGS. 2 and 3).
  • the sensing device comprises a fiat sensing plate 116 which overlies the used bobbin 82 as shown in FIG. 6 passed into the sorting unit, small end first, being supported at the entry end of the unit on a swinging arm 118 hinged to the sensing plate and to a pivot pin 12% carried by the housing; and supported at the exit end of the sorting unit on a similar swinging arm 122 hinged to the exit end of said sensing plate 116.
  • Micro-switches 124 and 126 are connected to be actuated respectively by arms 118 and 122.
  • a tab 127 extending from one side of the arm 118 and bent at right angles thereto provides a cam actuating surface for engagement with the actuating arm of microswitch 124.
  • a tab 128 extending at right angles from one side of the arm 122 provides a cam actuating surface for the switch arm of micro-switch 126.
  • the entering micro-switch is normally open, Whereas the exit microswitch is normally closed.
  • the ejecting mechanism referred to comprises two air jets 13d and 132. connected with a compressed air line 134 having therein an open and shut valve 136 controlled by a solenoid 138.
  • the arrangement is such that when both the entry and exit micro-switches are closed the solenoid 138 is energized opening valve 136 so that a blast of air is directed against the discarded bobbin in the sorting area to eject said bobbin. Movement of a discarded bobbin into the sorting area causes the sensing plate to be raised closing the entry micro-switch. While the exit end of the sensing plate is also raised the exit micro-switch remains closed unless the thread mass on the bobbin is sutficient to open the switch.
  • the entry end of the sensing plate 116 is raised closing the entry microswitch 124. This is the full line position of FIG. 6. See also FIG. 11. Under these conditions the exit micro-switch 126 remains closed so that the solenoid 138 is energized allowing compressed air to escape through the air jets 13%, 132, to eject the used bobbin.
  • the sensing plate 116 When a bobbin having more than the predetermined r number of thread wraps enters the ejector the sensing plate 116 will be lifted to the high position shown in dotted lines in FIGS. 6 and 8 causing the exit micro-switch 12.6 to open, thus de-energizing the solenoid 138 which has become momentarily energized as the sensing plate 116 rises through the empty bobbin position. Under these conditions the air jets are ineffective to eject the piece bobbin which continues on its way through the ejector mechanism. It will be understood that the momentary energization of the solenoid 138 is insufiicient to affect the direction of travel of the piece bobbin in its passage through the ejector.
  • Bobbins ejected from the sorting zone are discharged into a suitable container over a discharge plate 142 which slopes downwardly from one side of the conveyor 86.
  • a discharge plate 142 which slopes downwardly from one side of the conveyor 86.
  • the bottom end of the empty bobbin of larger diameter to become stuck between the sensing plate and the conveyor causing the bobbin to be swung 180 degrees by the air jets without actually leaving the conveyor.
  • a bobbin guide post 144 is mounted on the discharge plate 142 to obstruct the swinging movement of the small end of the bobbin while the butt end of the bobbin is freed by the action of the air jets as indicated by the dot and dash line positions of FIG. 4.
  • Piece bobbins such as that described at 145 are jogged around the curve provided by a corner housing 146 and will slide down the closed chute 90 which at its lower end is formed with a laterally inclined plate 148 adapted to roll the piece bobbin 145 onto a shelf on the elevating conveyor 92.
  • the piece bobbin elevating convey-or 92 is similar to the elevating conveyor 42 previously described, comprising a pair of sprocket chains 152 riding on pairs of sprocket Wheels 154, 156, and 158, whereby the piece bobbin 145 is moved by steps to an elevated position, and is dropped into the chute 94 formed to cause the piece bobbin to be deposited, large end down, in a magazine can 26.
  • the piece bobbin elevating conveyor 92 is driven in a manner similar to the main elevating conveyor 42 through connections which include an electric motor 160, a reduction gear unit 161, and a driving clutch disc 162 loose- 1y mounted to turn on a driven clutch shaft 163, and continuously driven from the reduction gear unit.
  • the clutch shaft is driven through successive increments of one revolution by means of a one revolution clutch consisting of a driven key supporting disc 164 secured to the shaft 163, a spring pressed key 165 mounted thereon and biased into locking engagement with one of several peripheral sockets 166 in the rotating clutch disc 162, and a control finger 167 which normally engages and holds the key 165 in a retracted inoperative position.
  • the supply magazine is caused to advance one bobbin position with each advance of the winder units of the machine by the operation of a limit switch 2L8 which is actuated to a closed position by conventional mechanical linkage which may include a trip lever 174 (see FIG. 3) operated by the passage of each successive bobbin peg 175, thereby momentarily energiz' ing an electrical circuit.
  • the switch 2L5 when closed, energizes solenoid 36 causing the armature 35 (see FIG. 1) to be momentarily withdrawn permitting a stepped advance of the magazine 20.
  • the solenoid 36 is energized as shown in the fragmentary electrical diagram of FIG. 14.
  • the piece bobbin elevating conveyor 92 and the full bobbin elevating conveyor 42 are in turn given a stepped advance by the operation of a limit switch 4LS which is actuated to a closed position by conventional mechanical linkage which may include a trip lever 176 (see FIG. 3) operated by the passage of each successive bobbin peg 175, thereby momentarily energizing an electrical circuit.
  • the solenoid Sol. 2 is energized as shown in the fragmentary electrical diagrams FIGS. 12 and 13 to step feed the piece bobbin conveyor 92.. Assuming that the switch 3LS is closed, the solenoid Sol. 3 is energized to step feed the main full bobbin elevating conveyor 42 (see FIG. 12).
  • the piece bobbin elevating conveyor has the capability of placing piece bobbins in each successive bobbin can 26 of th supply magazine.
  • most of the discarded bobbins will be classed as rejects only an occasional random piece bobbin will be supplied to the supply magazine on the piece bobbin elevating conveyor.
  • the bobbin elevating conveyors are so arranged and controlled as to cause the full bobbin conveyor to supply full bobbins only to supply cans 26 of the feed magazine which have not already been filled by the piece bobibn elevating conveyor 92.
  • the full bobbin feeding station is two steps removed from the piece bobbin station around the magazine in the direction of feed. With each step feed of the magazine a detector device determines whether the supply can brought to the full bobbin feed station has already been filled from the piece bobbin conveyor. If so, a normally closed switch 3LS is opened disconnecting solenoid Sol. 3 so that the full bobbin elevating conveyor remains stationary (see FIG. 13).
  • the detector device referred to, see FIGS. 9 and 10, comprises a switch arm 178 rotatably supported on a post mounted externally of the supply magazine on a bracket 1S2 fixed to the machine.
  • the switch arm 178 is in the form of a flat plate secured to a vertically arranged stem 184 carried by'a rotatable hub 186 loose on the post 180, a rearward extension of the switch arm 178 extends normally across the path of movement of the loaded bobbins or cops about the magazine axis, this extension bein g located below the side wall elements of the supply cans 26.
  • the advance of the multiple winding units of the travelling winder is accompanied by a corresponding stepped advance of the supply magazine 21 in order to drop a wound bobbin onto the next succeeding bobbin peg of the winder at its bobbin supply station.
  • the advance of the winding units of the winder causes a bobbin peg 175 to actuate lever arm 174 to close switch 2L8 and in a measured amount of time, switch 4L8.
  • Solenoid Sol. 2 is energized producing a stepped movement of the piece bobbin elevating conveyor 92. Assuming that the stepped movement of the supply magazine 20 has not brought a piece bobbin to the full bobbin feeding station, the switch 3LS is closed as in FIG. 12 causing the solenoid Sol. 3 to be energized producing a stepped movement of the full bobbin elevating conveyor 42 and the discharge of a full bobbin into the can 26.
