  • Actuating means is provided for moving the carrier to a first position in which the yarn is wound onto the bobbin tube, from there to intermediate position in which the fully wound bobbin is disengaged from the carrier, to a third position in which the carrier receives a first bobbin tube, and back to the first position.
  • Winding means is provided for winding the yarn onto the bobbin tube when the carrier is in the first position, and operative means is provided for severing the yarn intermediate the winding means and the ejected bobbin in response to return movement of the carrier to the first position, and for attaching the leading end of the severed yarn to the empty bobbin tube held by the carrier.
  • the present invention relates to bobbin changing devices.
  • a more specific object of the invention is to provide such a bobbin changing device which is adapted for fully automated operation.
  • An additional object of the invention is to provide an automatic bobbin changing device in which not only removal of the fully wound bobbin and replacement thereof by a new empty bobbin tube are automatically accomplished, but in which also the yarn is severed when such substitution takes place.
  • a concomitant object of the invention is to provide such an automatic bobbin changing device in which the leading end of the thus-severed yarn is automatically attached to the new empty bobbin tube.
  • an automatic bobbin changing device which comprises a movable carrier including means for releasably holding a bobbin tube thereon, and actuating means operatively connected with the carrier.
  • the actuating means is provided for moving the carrier to a first position in which yarn is wound onto a bobbin tube held by the carrier to thereby form a bobbin, further to an intermediate position in which the fully wound bobbin is disengaged from the carrier, a third position in which the carrier receives a fresh empty bobbin tube, and back to the above-mentioned first position.
  • Our novel automatic bobbin changing device further comprises winding means for winding yarn onto a bobbin tube held by the carrier when the latter is in the first position, and also operative means for severing the yarn intermediate the winding means and the ejected bobbin in response to the return movement of the carrier to its first position, and for attaching the leading end of thesevered yarn to the empty bobbin tube held by the carrier when the same returns to its first position.
  • FIG. 1 is a schematic view of a bobbin changing device in accordance with the present invention in one operative position thereof;
  • FIG. 2 is a view similar to FIG. 1, but showing a bobbin changing device in a second operative position thereof;
  • FIG. 3 is similar to the preceding figures and shows the bobbin changing device in a third operative position thereof.
  • FIG. 4 shows diagrammatically the operative intercounection of the various elements of the novel bobbin changing device.
  • the novel automatic bobbin changing device disclosed herein and shown in the figure comprises a pair of transversely spaced arms 1, only one of which is shown, which are pivotably mounted at their one end on a pivot 2 provided on a support 3, such as the frame of a winding machine.
  • the other end of each arm 1 is provided with means for releasably holding a bobbin tube, such as a carrier 4, which is not shown in detail but may be constructed in accordance with the earlier mentioned copending application.
  • the carriers 4 engage an elongated bobbin tube 5 onto which a yarn package 6 is wound.
  • the winding of the yarn onto the tube 5 is accomplished by engagement of the tube 5 with a traversing roller 7, that is a roller which is capable of moving the yarn axially of the tube 5 from end to end thereof and thus traversing the yarn 8, which is nipped between the roller 7 and the tube 5.
  • a traversing roller 7 that is a roller which is capable of moving the yarn axially of the tube 5 from end to end thereof and thus traversing the yarn 8, which is nipped between the roller 7 and the tube 5.
  • the roller 7 engages no longer the tube 5 but the yarn package 6. In either case, however, the result is the same, namely that rotary motion is transmitted from the traversing roller 7, which is driven, to the non-driven tube 5 and the yarn package 6 thereon.
  • both of the arms 1 are turnable about their respective pivots 2 between two extreme positions, and for this purpose an actuating arrangement 11 is provided which may be of any suitable type, many of which are known in the art.
  • the arrangement 11 is a doubleacting pneumatic cylinder which is tiltably secured at a pivot 12 carried by a support, such as the machine frame 3.
  • the piston rod of the arrangement 11 is hingedly connected at to the arms 1 so that, when the piston moves out of the arrangement 11, the arms and the yarn package and bobbin tube carried thereby will be moved in downward direction .as seen in the drawing, whereas when the piston 9 moves into the cylinder of the actuating arrangement 11, the arms will be lifted in upward direction.
  • a feeding arrangement 13 for new empty bobbin tubes 5 Arranged upwardly of the arm 1 and, specifically, upwardly of the bobbin tube and yarn package carried by the arms 1, is a feeding arrangement 13 for new empty bobbin tubes 5.
  • the arrangement 13 is provided with an outlet end and with a closing member 15 which is pivotable about an axis 16 and normally positioned by a biasing member, such as a spring 1'7, in such a manner that it will substantially close the outlet of the feed arrangement 13, and will prevent the empty bobbin tubes 5 from passing through the outlet.
  • a wall portion 19 of the feed arrangement 13 is so shaped at the outlet end of the arrangement that one of the empty bobbin tubes 5 is always held in readiness to replace a fully wound bobbin.
  • a chute 20 and a receptacle such as an intermittently operable conveyor 21.
  • a nozzle 22 of an air supply pipe which can be opened and closed by a suitable valve arrangement, such as a solenoid valve, which in the presently illustrated embodiments is shown as operating a valve member which opens and closes the supply of air to the nozzle 22.
  • a suitable valve arrangement such as a solenoid valve
  • air is used for illustrative purposes only since many dilferent gases are suitable for the purpose which will be described below.
  • the solenoid valve is identified with reference numeral 24 and it will be noted that it is operated by the arms 1 when the same contact a switch 25 of an electric circuit 29 connecting this switch with the solenoid valve.
  • the limit switch 26 mentioned above is provided for the purpose of sensing the thickness of the yarn package 6 and it will be seen that it is connected via an electrical circuit 29a with the actuating device 11 or, more precisely, with a valve block which controls the admission of pressure fluid to the actuating device 11.
  • the limit switch 26 senses that the yarn package 6 has reached 4 a determined thickness, it will actuate the valve block (which is shown in FIG. 4) so that fluid will be admitted into the actuating device 11, the piston 9 will be withdrawn, and the arms 1 thus lifted as seen in FIG. 1.
  • the arms 1 continue to rise under the influence of the inwardly moving piston 9 of the actuating device 11 until they reach their third or extreme upper position in which the foremost one of the free empty tubes 5 in the feed arrangement 13 automatically becomes engaged between the free ends of the arms 1.
  • the feeding arrangement 13 is open at its opposite lateral sides and since it is only as wide as the axial length of the tubes 5, that is of a lesser width than the spacing between the arms 1 so that the arms 1 can move upwardly beyond the plate member 15 and engage the foremost tube 5.
  • the arms I When the arms I reach their lowermost position in which the new bobbin tube 5 engages the traversing roller 7 to be driven thereby, the arms actuate the limit switch 25 which, as pointed out earlier, is connected via an electrical circuit 29 with the solenoid valve 24.
  • the limit switch 25 is also connected, however, with the valve block and thus automatically shuts off the supply of pressure fluid to the actuating device 11.
  • the solenoid valve 24 activates the solenoid valve 24 so that the valve member 23 thereof is withdrawn from its position in which it closes the orifice 22 of the air supply pipe whereby a brief blast of air or other gas used in lieu of air is directed in upward direction as shown in FIG. 3.
  • This air is sufiicient to lift the reserve length of yarn 8 upwardly in form of a loop 28 and to press it against the surface of the now rotating bobbin tube 5.
  • the loop 28 is entrained by this engagement and is carried along by the rotating bobbin tube 5 towards the left as seen in FIG. 3 until it becomes caught between the tube 5 and the traversing roller 7.
  • the yarn is broken and only new yarn 8 is henceforth wound onto the rotating bobbin tube 5 until a new yarn package 6 has come into existence and reaches its predetermined thickness, whereupon the process starts again.
  • the device 28' is a conveyor which is arranged to carry away the fully wound bobbin shown in FIG. 2, then it is advantageous that this conveyor be intermittently operable so that it may stop while the replacement of the fully wound bobbin with a new bobbin tube, and the severing of the yarn, take place.
  • this conveyor be intermittently operable so that it may stop while the replacement of the fully wound bobbin with a new bobbin tube, and the severing of the yarn, take place.
  • this entire substitution operation goes forward, such an intermittent operation may not be necessary at all.
  • An automatic bobbin changing device comprising, in combination, a movable carrier including means for releasably holding a bobbin tube thereon; actuating means operatively connected with said carrier for moving the same to a first position in which yarn is wound onto a bobbin tube held by the carrier to thereby form a bobbin, an intermediate position in which the fully wound bobbin is disengaged from said carrier, a third position in which said carrier receives a fresh empty bobbin tube, and back to said first position; winding means for winding yarn onto a bobbin tube held by said carrier when the latter is in said first position thereof; and operative means for severing the yarn intermediate said winding means and the ejected bobbin in response to return movement of said carrier to said first position thereof, and for attaching the leading end of the thus severed yarn to the empty bobbin tube held by said carrier.
  • a device as defined in claim 2, wherein said feed comprises a chute in which said empty bobbin tubes are located, and having an outlet portion in which the foremost one of said empty bobbin tubes is held ready for engagement by said holding means on said carrier.
  • said feed further comprising an ejecting portion extending into the path of movement of the fully wound bobbin when said carrier moves to said third position, to thereby disengage said bobbin from said carrier.
  • a device as defined in claim 2 and further comprising detector means operatively connected with said actuating means and arranged to scan the bobbin on said carrier in said first position of the latter for operating said actuating means when the diameter of said bobbin increases to a predetermined extent.
  • said actuating means includes a cylinder and a double-acting piston reciprocable therein.
  • a device as defined in claim 1 and further comprising sensor means arranged to be activated by said carrier when the same is in said third position, and operatively connected with said actuating means for actuating the same and initiating return movement of said carrier to said first position.
