Definitions
- the supervisory work on a double-twist machine should therefore be so automated that the machine can run completely unsupervised at least for some long period of time, yet the complete system must not become overcomplicated; indeed, construction should be kept as simple as possible, with a view to keeping first costs low and to reducing the likelihood of disturbances and breakdown. Also, a system of this kind, as well as considerably reducing the human labour required, should work more rapidly and more uniformly than with unaided human labour, with the likelihood of increasing output per manhour and machine utilisation.
- a preparation station is provided in the form of a pneumatic threader. This step reduces handling times but provides only partial automation.
- the creel bobbin and the twisted or doubled yarn bobbin (hereinafter called the doubler bobbin) or the core therefor are changed together and form a unitary group throughout until unwinding is completed.
- creel bobbin as used in this context and hereinafter is intended to denote any kind of creel bobbin --i.e., including creel bobbins in a double-row arrangement.
- the doubler bobbin and the creel bobbin are brought conveniently close to one another and the yarn ends are knotted at a given time, and the group comprising the doubler bobbin and the creel bobbin is kept ready for automatic insertion at the twisting or doubling station.
- a bobbin carrier fitted with a creel bobbin can be provided with a doubler bobbin or a core therefor outside the twisting or doubling station, and the yarn which has been drawn off the creel bobbin and threaded into the twist spindle tube can there be placed on the doubler bobbin tube or knotted between the creel bobbin and the doubler bobbin to repair a yarn reak.
- the bobbin carriers are exchanged in one direction of movement without reversal of direction from one side of the machine to the other, and during the exchange movement the fresh doubler bobbin or doubler bobbin core is removed from its carrier and, after ejection of the bobbin from the bobbin frame, is inserted into said frame.
- the doubler bobbin ejected from the bobbin frame is placed on the ejected creel bobbin carrier.
- the creel bobbin carrier and the doubler bobbin forming the group therefore stay together.
- the creel bobbin carrier combined with the doubler bobbin is moved away from the preparation station adjacent the doubling station stepwise downwards, then forwards to the stand-by station, and thence to the insertion station.
- the machine operative must see to it that there is at least one group comprising a creel bobbin and doubler bobbin or doubler bobbin core available for each twisting station. If allowance is made for likely yarn breakages, a tWo-for-one twister can at the end of a shift be brought into a state enabling it to run through the next shift without any supervision, since a group is exchanged not only upon exhaustion of the creel bobbin but also at every yarn breakage, but the machine continues to run undisturbed whether the operative sees to the particular spindles concerned immediately or at some later time.
- a changer apparatus movable along the machine is provided for automatic changing of the group comprising the creel bobbin carrier with the bobbin and the doubler bobbin or doubler bobbin core.
- a gripper preferably in the form of a fork and adapted to move transversely of the longitudinal axis of the machine and vertically, is provided on the changer apparatus, and the fork prongs engage in guides of the bobbin carrier to raise the same to the level of the operative position and, in a non-reversing movement to initiate the ejection of the creel bobbin carrier which has been operative and its replacement by another.
- the changer comprises two other grippers, preferably in the form of expanding mandrels, movable transversely of the machine axis and vertically, to engage the cores of the double bobbins and insert them into the bobbin frames which are ready to receive them or remove them. These devices permit changing the groups.
- FIG. 1 is a vertical section through a double-twist machine taken in the region of one twisting station;
- FIG. 2 is a side view of the bobbin carrier change fork
- FIG. 3 is a plan view corresponding to FIG. 2'
- FIG. 4 is a side view of the yarn detector
- FIG. 5 is a plan view corresponding to FIG. 4.
- a machine frame 1 has mounted in it, in known and conventional manner, a spindle bank 3 receiving double twist spindles 5 mounted by means of their wharves 4.
- the wharves are in known manner driven tangentially by a belt 6 associated with a conventional pressing roller 7.
- Yarn 9 paid off from a creel bobbin 8 runs conventionally through a hollow tube 1% issues radially from revolvable plate or bowl 11 at 12 and runs via a yarn detector 13 and lead roller 14 to a traversing yarn carrier 15, to be wound by means of a friction roller 16 on to a tube 17.
- a double-row arrangement i.e., of two creel bobbins 8 disposed one above another-the t'wo yarns travel along the path just described.
- a special spindle must be provided if the steps according to the invention for automating the various operations are to be carried into effect.
- a carrier 13 of the bobbin 8 is kept stationary by magnets 19, 26 in a manner known per se.
- the carrier 18 isin accordance with an earlier suggestion which is not, however, prior artprovided with a double bearing 21 having a conical outside surface engageable in a matching conical socket part 22 of the rotating plate or dish 11.
- the plate or dish is formed near the aperture 12 with a radial slot 23 which extends into the socket part 22.
- prior art--the spindle can be stopped in an arbitrary position which, in the present case, is such that the aperture 12 and slot 23 in the turntable 11 always point to the same place. In order not to overload the drawings, the means therefor are not shown.
- the carrier 18 has guides 24 whereby it can be engaged (as hereinafter described) and raised together with its bearing 21 and moved from one side of the machine to the other.
- a V-bar 25 Disposed in the machine frame 1 is a V-bar 25 which can, conveniently, be mounted near one foot 26 of the frame 1.
- the bar 25 forms, as it were, a single track which extends along the length of the machine and on which wheels 27 of a U-shaped frame 28 of a bobbinchanging apparatus 29 run.
- the frame 28 also bears via a roller 30 in a U-bar 31 secured to the bank 3.
- the changer apparatus 29 is driven by an electric motor 32 which picks up its current from busbars 34 via a pick-up bow 33.
- a compressor for operating the pressing cylinder is supplied with electricity in the same way.
- the compressor is mounted in the changer apparatus 29 but is not shown. Very advantageously, the compressor is of a pistonless kind known per se.
- a lifting device 38 can be moved transversely of the longitudinal axis of the machine, and roll mountings 39 are provided for this purpose.
- a piston rod 41 Secured thereto, by means of a support member 141 for guiding the cylinder 40, is a piston rod 41.
- a fork 42 Secured to the bottom end 142 of the cylinder is a fork 42 which can engage in the guides 24 in the bobbin carrier 18, as can be seen more particularly in FIGS. 3 and 4.
- the prongs of the fork 42 are long enough to receive two bobbin carriers 18 and transport the same horizontally and vertically.
- the fork 42 can move as far as a preparation station which will be described hereinafter.
- the carrier 141 Disposed on the carrier 141 in a second plane above the fork 42 are two expanding mandrels 43, 44 which are adapted to engage tubes 45 of doubler bobbins 46 and to insert them into carriers 47 which are ready to receive them or to remove them from carriers.
- No elaborate means for turning up the bobbin tube and its carrier part from the horizontal position to the vertical are needed.
- the crucial action as can be seen from FIGURE 1 is that the carrier part for the tube of the bobbin is swung around on an arm along the dotted radial lines between the two shown positions.
- the carrier 47 includes a hinged part carrying the bottom tube 1'7.
- the carrier comprises an arm 70 which can be swung to the full line position from the dotted line positions indicated by the radial lines. At the full line position the hinged part is swung upwards (to the said raised position) to align the bottom core with the mandrel 44, and any suitable means such as an electromagnet may be provided for this purpose.
- the mandrels 43, 44 are each in the form of a rubber member which can be expanded by compressed air supplied through a hollow piston rod 48, to clamp the tube 45. Through the agency of pistons 49, the mandrels 43, 44 can be moved up and down pneumatically by means of pistons 49 in cylinders 50.
- the cylinders 40, 50 have their supplies controlled by a distributing valve 51 in the form of a known electric valve for pneumatic programme control.
- the various movement phases for the bobbin-changing system will be described in greater detail hereinafter.
- the bobbins 46 are taken from the raisable carrier 47 and travel, in the direction indicated by the diagrams in chain-dotted lines, to a preparation station 52 where they are placed on the associated bobbin carrier 18.
- the bobbin 46 is guided by a shaft 53 which continues to below the station 52 and which has an open part 54 so that the bobbin carrier 18 can be lifted off its spindle and moved into the preparation station in a single movement transversely of the machine longitudinal axis from the front to the back.
- the shaft 53 is so formed that the machine operator has access into it from the right and from the left with both hands.
- the station 52 has a carrier 55 and is additionally secured by a spring-biased flap 62 rotatable around a spindle 63.
- the carrier 18 and its associated bobbin 46 on the carrier 55 stay at the station 52.
- the carrier 55 has a manually releasable locking device 56.
- the carrier moves downwards along guide 57 and is braked by a piston, with rod 59, moving in a cylinder 58.
- the carrier 55 together with the group comprising the carrier 18 and bobbin 46, moves into a position 162 which is shown in chain lines and in which the carrier 18 is transferred to a roller track 60 over which the group passes to a chain line position 61 where it moves into the range of the fork 42, which is also shown in chain-dotted lines.
- the machine is controlled by means of the yarn detector 13.
- the yarn detector system comprises a known self-threading yarn carrier 113 with an entry hoop 114.
- a spring-biased detector lever 116 is pivoted near the point 115 where the yarn passes through.
- the detector lever 116 pivots into the position 116' to close the control circuit and thus initiate the stopping of the spindle, raising the carrier 47, moving the changer 29 to the location of the disturbance and locking the changer 29 at such location.
- a programme control 51 in the changer 29 is started and changes a group comprising a carrier 18 and tube 45 or bobbin 46.
- the last item on the programme of this control is the release of the changer 29 so that the same is then free for further changing operations and can readily be called automatically to the location of the next disturbance. After release the changer can either remain at the place of release until it is required for a fresh disturbance, or move into a central position-and thus be able to travel the shortest distance to any fresh disturbanceor patrol along the length of the machine.
- the machine operates as follows.
- the spindle 5 stops with the slot 23 pointing to the front.
- the changer 29 is called to the disturbance and locked near the disturbed spindle.
- a fork 42 with the prongs long enough to receive two bobbin carriers consecutively is at this time in the chain-line position A, but moves immediately to position B and picks up the group 18, 46 at the position 61.
- the lifting cylinder 40 then rises until the fork reaches position C at the level of the operative position of the spindle 5.
- the mandrel 43 then descends, engages with the tube 45 of the bobbin 46 and moves it into the top solid-line position 46.
- the mandrel 44 has engaged with the tube 45 of the bobbin 46 which, together with the carrier 18 and bobbin 8, is associated with the spindle 5 actually in operation at that particular time.
- the mandrel draws the bobbin 46 off the carrier 47.
- the lifting device now moves from front to rear transversely of the machine longitudinal axis so that the fork 42 moves from position C to position D, the mandrels 43, 44 moving to the left (with respect to FIGURE 1 orientation) by corresponding amounts.
- the lifting device 40 then rises to bring the fork 42 into position E.
- the carrier 18 has therefore come into the position 18 in which the bearing 21 has been removed from its matching socket 22.
- position F the fresh group 18, 46 is right at the twisting station, the carrier 18 and bobbin 8 being above the re volvable plate or dish 11 and the wharve and the bobbin 46 being above the carrier 47. All that remains is the lowering movement.
- position G the fresh carrier is lowered into its matching member 22.
- the carrier 18 which was previously in operation is deposited at the preparation station 52.
- the mandrels 43, 44 are lowered until they engage with the associated bobbin, the corresponding bobbin 46 which forms part of a new group being released, while the mandrel 44 releases the bobbin 46 of the group previously in use so that such bobbin can be combined with the ejected carrier 18.
- the complete lifting device 38, and therefore the fork 42 and mandrels 43, 44, are returned to the original position.
- the original position for the fork 42 is the position H.
- the programme control then releases the changer 29 so that the same can be moved to the place of any fresh disturbance.
- the upwards movement of the bobbin 46 produced by the mandrel 43 pulls the yarn 9 upwards, and upon the mandrel 43 and therefore the bobbin 46 moving transversely, this is therefore introduced automatically into the detector 13 and carrier so that twisting can be resumed immediately after the carrier 47 has been lowered.
- the yarn 9 has also come near the detector 13 and is introduced by the pivoting yarn inserter 117 into the passage 115.
- the pivoting of the inserter 117 is produced by a cylinder 118 controlled by the programme control.
- the machine operative whatever the fault-a yarn breakage or exhaustion of the bobbin 8-removes the group comprising the ejected carrier 18 and bobbin 46 and inserts a fresh group.
- the latter can be either a group which has still not fully unwound and which merely requires the yarn break to be repaired, or a fresh group in which the unwinding from the bobbin 3 has not startedi.e., the tube of the bobbin 46 is still empty. Assembly, threading-up and knotting are all performed outside the machine, and the machine operative can, for instance, push round a trolley containing appropriately assembled groups.
- the machine operative releases the carrier 55 so that the group can be deposited on the roller track 60. If required, the group need not be replaced if the yarn breaks; instead, the yarn can be knotted while the group is at the preparation station.
- a method of servicing a double twist machine having a plurality of stations comprising: associating a threaded creel bobbin to doubler bobbin means at a preparation station including operatively securing yarn from the creel bobbin to the doubler bobbin means; cycling the associated creel bobbin and doubler bobbin means to a standby station and from there to an insertion station; sensing an interruption of the passage of yarn from an in place creel bobbin to an in place doubler bobbin means at a doubling station, moving said associated creel bobbin and doubler bobbin means toward said doubling station and withdrawing said in place creel bobbin and in place doubler bobbin means from said doubling station; then installing said associated creel bobbin and doubler bobbin means in place at said doubling station and depositing the formerly in place creel bobbin and formerly in place doubler bobbin means at said preparation station.
- the method of claim 1 further including the steps of securing broken yarn ends to one another; and reassociating the formerly in place creel bobbin and the formerly in place doubler bobbin means to constitute an associated creel bobbin and doubler bobbin means at said preparation station.
- the method of claim 1 further including the steps of: replacing an empty formerly in place creel bobbin with another creel bobbin having yarn thereon; associating said other creel bobbin with doubler bobbin means to constitute an associated creel bobbin and doubler bobbin means at said preparation station.
- creel bobbin includes a twist spindle tube and the doubler bobbin means includes a core, wherein the creel bobbin and doubler bobbin means are associated by drawing yarn oif the creel bobbin and threading it through the twist spindle tube and onto the doubler bobbin core.
- a double twist machine having: means defining at least one preparation station, means defining at least one standby station, means defining at least one insertion station and means defining at least one doubling station at Which yarn is wound from a creel bobbin onto doubler bobbin means all of said one stations being generally disposed in a common plane; means for sensing an interruption in the passage of yarn from the creel bobbin to the doubler bobbin at said doubling station; a changer apparatus disposed at said insertion station at least upon the sensation by said sensing means of a yarn interruption and comprising:

- the changer also includes a doubler bobbin core engaging means, separate from said fork member, and mounted for movement vertically and transversely of the machine; said core engaging means being constructed and arranged to accept the creel bobbin associated doubler bobbin means from the support of said fork member at said insertion station and to emplace the accepted doubler bobbin means at the doubling station, said core engaging means also being constructed and arranged to deposit the disengaged doubler bobbin means at the preparation station.
- the changer apparatus comprises a U-shaped frame; a longitudinal track on said machine externally thereof; said frame being mounted on said track; said machine having means thereon for supporting and guiding the U-shaped frame.
- the double twist machine of claim 6 further including a generally vertical track extending between said preparation station and said stand-by station; a manually lockable carrier on said vertical track; said lockable carrier being lowerable along said track to move associated creel bobbin and doubler bobbin means from said preparation station to said stand-by station.
