Definitions

  • ABSTRACT A spinning frame or a ring twister frame with semi-automatic doffing and donning is provided with a doffing bar on the usual ring rail with projections which in one position of the doffing bar are opposite each wound bobbin.
  • the ring rail is pneumatically lowered when the bobbins are fully wound to a posi' tion just below the normal starting position and the doffing bar moved so that the projections are underneath the bottom ends of the bobbins.
  • the pneumatic cylinder used to bear down the rail is double acting, and when the doffing cycle is manually started raises the ring rail to a position high enough to lift the wound bobbins ofi' their spindles.
  • a wall is tilted, forming a chute into which the bobbins fall, and a conveyor in the bottom of the chute carried them to a full bobbin container. 1n the case of spinning frames, there is carried on the ring rail a donning tube with holes opposite each spindle.
  • Spinning frames and also ring twister frames are extensively used in the textile industry. Both types of frames wind bobbins and are provided with ring rails carrying thread guides which can move around each ring. Both types of frames wind at very large number of bobbins simultaneously and rapidly, the empty bobbins on the spinning frames having enlarged bot toms, while the bobbins on a ring twister frame have enlargements both top and bottom and so resemble somewhat elongated spools.
  • the ring twister frames are provided with feeds for yarns to be twisted or plied, whereas the spinning frames in general use a single yarn and the winding of the bobbin ordinarily does not impart additional twist.
  • spinning frames technically they carry out both a spinning and winding operation, but in the industry the machine is referred to as a spinning frame, and this nomenclature will be used throughout the specification and claims.
  • a builder motion causes the ring rail to gradually move up the bobbin and to oscillate in each particular position so that layers of yarn are wound uniformly on the bobbins.
  • a switch is provided which is actuated by the ring rail in its highest position when the bobbins are fully wound. Historically this is referred to as a knock-off switch," and it actuates, usually electro-pneumatically, a sequence of operations which includes tipping up upper thread guides, bearing down the ring rail, and in its bottom position turning off the frame drive motor.
  • the present invention provides semi-automatic dofiing and/or donning of multiple spindle spinning frames and ring twisters.
  • the new operations are preferably power actuated, electro-pneumatic actuation being cheap and reliable and therefore preferred, but the invention is not limited to this kind of power actuation.
  • the oscillation of the ring rail during winding of the thread, such as warp or filling threads, is effected with counterweights and traversing mechanism with a chain which is gradually let out in exactly the same manner as in the ordinary manually doffed and donned spinning frames. This is an advantage as the invention can be applied to standard spinning frames at very modest cost and without rebuilding the whole frame.
  • the present invention is, therefore, not directed to the broad idea of mechanical dofling and/or donning; it is directed to a much cheaper and/or faster semi-automatic dolfing and donning device which operates on a difl'erent principle.
  • the present invention includes the following sequence of operations, which will first be described very briefly and then in more detail. The description will be in connection with spinning frames.
  • the bearing down of the ring rail after full bobbins have actuated the knock-0E switch is to a point below the normal low position of the ring rail for starting winding.
  • the additional lowering is sufi'icient so that according to the present invention projections carried by the ring rail can be moved into position under the bottoms of the wound bobbins.
  • the next operation involves a manually initiated doffing cycle, including a starting button, which raises the ring rail, preferably by power actuation as the amount of friction of the very large number of bobbins on their spindles is too great for the ordinary counterweights which produce oscillation of the ring rail during winding unless they are of very large size.
  • the present invention includes in a broad aspect devices in which the raising of the ring rail at this point is not power actuated, but power actuation is greatly preferred. This can be very simply effected by a double acting cylinder bearing down the ring rail. In a further, more specific aspect this preferred operation is included.
  • the ring rail need not be and preferably is not raised to a position as high as the position it occupies when the bobbins are fully wound and the knock-off switch is actuated.
  • the reason why it is unnecessary to raise the ring rail to the maximum elevated position is that the spindles are much shorter than the hollow empty bobbins and, therefore, the wound bobbins can be lifted up off their spindles without raising the ring rail to the point where the knockoff switch would again be actuated.
  • the fully wound bobbins lifted up by the projections on the ring rail above their spindles fall outward, away from the center line of the frame, into suitable containers.
  • the chute Preferably they fall into a chute and a conveyor belt is started to move then to a final container at the end of the frame.
  • the chute can be stationary, but as this wastes aisle space between frames and makes the creeling of the roving packages more difficult, it is preferred to have the chute with a tiltable outer wall so that during winding no space is taken up. In this preferred form the chute wall is tilted out before or during the raising of the ring rail which efi'ects dofi'mg.
  • the pneumatic rewinding also eliminates incomplete rewinding, which can occur when the operation is manual.
  • the semi-automatic doffing which is a very important feature of the present invention, may be used with manual donning of empty bobbins on the spindles after the ring rail is borne down a second time to the winding start position. This reduces by more than half the time of manual dofiing and the effort, but it still wastes some doffing labor and also increases the time during which the spinning frame is not effectively winding bobbins, or rather reduces this time substantially but does not eliminate it completely. Therefore, in a further more specific aspect of the present invention semi-automatic donning is included. This is effected by a donning bar or tube which is carried by the ring rail in a position that does not interfere with the winding.
  • the donning bar has a hole opposite each winding spindle and empty bobbins are introduced into these holes upside down, the enlarged bottom of each bobbin of course preventing its falling through the hole.
  • another power device preferably another electro-pneumatic cylinder
  • swings the donning bar over the rings in the ring rail This is effected by swinging it in an arc, with gear segments meshing so that the donning bar is turned through 90 as well as the 90 rotation effected by swinging in the arc.
  • the total is 180, and now the empty bobbins drop down through the rings onto their spindles.
  • the donning bar is rocked back to its normal position; and if all empty bobbins fall on their spindles, the ring rail again drops to winding position and stops. If during the electrical delay an empty bobbin sticks or does not fall all the way down on its spindle, electrical stoppage can be effected and is desirable although not essential.
  • the machine operates without any malfunctioning, and when the ring rail returns to its winding position, slack is produced in the traversing mechanism chain, and it is rewound as has been mentioned above.
  • malfunction is protected against and a reset button provided, as is customary in mechanisms where it is desired to protect against temporary malfunction.
  • the automatic donning cannot be used practically with this type of frame because the enlargement at the top of each bobbin would prevent inserting the empty bobbins or cores upside down in the donning bar.
  • the automatic donning is, therefore, only applicable to the specific aspect of the present invention which is directed to spinning frames in which the top of empty bobbins or cores is not enlarged.
  • the present invention includes any projections which can be moved in by any mechanism that can be controlled to operate at the right point during the cycle and can be brought back into winding position before the end of the cycle and before the machine is started on a new winding cycle.
  • the projections on the ring rail which permit doffing at the right part of the cycle are of a flat bar having scallops spaced for the winding spindles. These scallops are preferably not a full semicircle, and of course between scallops there are straight projections.
  • a flat bar or an angle shape with a flat top section which will be generally referred to as a flat bar, is preferable as a means for introducing projections under each wound bobbin during the doffing cycle proper.
  • the bar slide lengthwise on the ring rail the very short distance which is needed to bring the projections under the wound bobbins, but of course the invention is not limited to this preferred form and it is possible to move a flat bar crossways of the ring rail. This operates perfectly butrequires a much more complicated and expensive operating mechanism, which is why the simple form of bar that slides a small distance longitudinally of the ring rail is preferred. This preferred form has several other advantages.
  • a second practical advantage of the preferred form of dofiing bar is that this is flat metal held only at the ends of the ring rail, and of course connected to the actuating rod, and therefore, if the frame is used with a different spindle position or if it is changed to operate with different sized bobbins, it is a simple matter to replace the flat bar with one of different dimensions to suit the changed conditions. Ordinarily a spinning frame will maintain the same gauge or dimension between spindles for long periods of time and so this advantage is less vital than others, but this does indicate the flexibility of the present invention. The additional advantage, even though only useful at infrequent intervals, is obtained without any additional mechanism and at minimum cost. Throughout the rest of the specification and including the description of the drawings and preferred embodiments below, the preferred flat, scalloped dofifing bar will be described, though, as has been pointed out above, the present invention is not limited in its broadest aspects to this preferred and desirable form.
  • the present invention reduces the strength required and the physical strain which in some cases can effect a further advantage and in any event presents working conditions, which are not objectionable.
  • the present invention therefore presents the very desirable situation that the large savings in cost and time are obtained with no offsetting disadvantages and in fact with further ad vantages.

  • FIG. 8 shows a portion of the ring rail during donning.
  • FIG. 6 A portion of the spinning frame itself is shown at l and is shown in detail in FIG. 6.
  • a ring rail 2 is provided which can be raised and lowered by rods 3, which extend through bushings 4 in the frame. These are actuated by a number of cross shafts 5 carrying counterweights 6 and arms 7, the ends of which bear on followers 8 of the rods 3.
  • One such shaft is shown in FIG. 6 and another in FIG. 5.
  • There are a large number of such cross shafts as the length of a ring rail in a long spinning frame can be 30 feet or more and it must be raised and lowered by rods at fairly short intervals to prevent bending of the ring rail.
  • FIG. 4 Since this arrangement of multiple cross shafts is conventional in spinning frames, only a portion of one arm is shown in FIG. 4, and a rod and an arm on FIG. 6, with another rod shown in FIG. 5 at the end of the frame, which connects to the traverse mechanism, which will be described below.
  • FIG. 5 shows a power actuated rewind for the transversing mechanism in addition to the conventional manual rewind. This will be described further below.
  • Each cross shaft 5 not only carries counterweights 6 but also carries a projecting arm 11, which arms are all connected together by a conventional driving bar, (not shown), extending the length of the frame.
  • a conventional driving bar (not shown)
  • the last cross shaft, and in some cases two cross shafts have their counterweights on the other side and are controlled by a traversing chain in the opposite direction.

  • FIG. 5 it will be seen that there is on its shaft 5 a further arm ll into which a traversing chain 12 is connected.
  • This chain passes over an idler roller 13, one end being fastened to an oscillating lever 14, which is provided with a counterweight 15.
  • the chain of course, is continuous.
  • the lever 14 is pivoted at 16 and is provided with a cam follower 117, which is actuated by a cam 18 driven from the drive of the spinning frame, which drive and connection are not shown as they are conventional in manual doff spinning frames. It will be noted that the cam 18 causes a slow oscillation of the lever 14.
  • This oscillation which has quite a short stroke, normally less than two inches, permits raising the ring rail so that layers of yarn can be wound on the bobbins, as will be described below.
  • the top of the stroke is determined by the chain 12.
  • Each stroke results in moving a ratchet wheel 119 one ormore teeth, controlled by pawl 20.
  • This turns a shaft 211, which through worm and worm gears 22 very slowly turns a drum 23.
  • the drum gadually unwinds the traversing chain 112 so that the ring rail moves up and down in short stroked oscillations, each one starting a little higher on the bobbin.
  • FIG. 5 represents a situation after the ring rail has been borne down for the last time in the dofiing and donning cycle.
  • the traverse chain 12 is rewound, and hence in FIG. the chain is shown with a considerable amount of slack, which is taken up by the rewinding.
  • FIGS. 4 and 6 it will be seen that the spindles 24 are turned in fours, (one pair on each frame side), by the conventional belts 25 driven by the main spinning frame drive. This mechanism is not shown in FIG. 1 as it is hidden by the ring rail 2 in its bottom position. In FIG. 4 empty bobbins 26 are shown on all of the spindles except at the extreme left. The tip of each spindle blade is lower than the bobbin tip, as can be seen in FIG. 4, and also is indicated in FIG. '7.
  • FIG. 8 shows the donning of the empty bobbins, which will be described below
  • FIG. 4 shows the situation after donning is complete, except of course for the left hand spindle in FIG. 4 where the empty bobbin has deliberately been omitted in order to illustrate the relative differences in height between the spindle tip and the bobbin tip.
  • Each of the bobbins has an enlarged bottom 27, as is conventional. This can be seen clearly in FIGS. 1, 4, 7 and 8.
  • FIG. 4 illustrates a position just after donning has been effected and just before lowering the ring rail 2 to its start of winding position.
  • the spinning frame is now stopped and remains stopped until a doffing cycle is started by a pushbutton, (not shown).
  • a pushbutton (not shown).
  • full bobbins which can be seen in FIG. I, can be marked by the operator, which may be desired. It is undesirable, although possible, to start the dofiing cycle automatically.
  • the semi-automatic operation is preferred in which the dofflng cycle is not started until the pushbutton is actuated. Air is introduced into a perforated pipe 39 through a fitting 38 which extends out at one end of the doffing bar 45.
  • FIG. 1 shows a portion of the tube 39 with one perforation. It is not shown, nor is tube 39, in FIG. 4 in order not to confuse the drawings.
  • FIG. 3 shows a portion of the bar 45 broken away, which makes the tube 39 and perforation visible. Also, of course, the tube 39 appears in section in FIGS. 7
  • the perforation in the tube 39 is offset to the left. If the perforation were exactly at the center of the arc of the scallop 46 and if the traveling thread guide 40 were exactly in the center of the rear arc of the ring 42, the straight blast of air might not have sufiicient sideways component to cause the traveling guide 40 to start moving around the ring 42, and this could result in a thread guide that was not blown out of the way of the doffing bar projections 47 when the latter is moved in the doffing cycle.
  • Cylinder 44 pulls a flat doffing bar 45 to the left.
  • the bar has semi-circular scallops 46, which are not a full semicircle and are separated by flat projections 47.
  • the great length of the flat bar 45 which extends the full length of the spinning frame, often 15 feet or more, could create a possibility of bending, and this is avoided by plastic blocks 56 of a plastic of low coefficient of friction, such as Teflon, mounted on the ring rail 2 every 2 feet or so and forming supports over which the bar 45 slides easily without bending.
  • the ring rail 2 is in the fomi of a channel with two skirts, along one of which a bent down portion of the bar 45 slides.
  • FIGS. 7 and 8 are sections taken at points where supporting blocks 56 are located.
  • FIG. 4 shows the bar 45 in the winding position with the scallops opposite the bobbins.
  • the bar has been moved to the left, and now the projections 47 are moved under the enlarged bottoms 27 of the bobbins. Air is then cut off from the cylinder 44, which is double acting, but does not need to remain in its actuated position as the friction of the long bar 45 on the plastic supports 56 prevents any movement of the bar except under the actuation of the cylinder 44.
  • Air is now introduced in the other end of the double acting cylinder 35, (FIG. 6), through a pipe 48.
  • This causes the lever to move in a counterclockwise direction, which positively forces up the ring rail 2.
  • air can be bled through the pipe 36 through a restricted opening so that the rising of the rail will not be too sudden or jerky.
  • FIG. 1 shows the projections 47 engaging the bottoms 27 of the bobbins
  • FIG. 7 shows a similar engagement but at the point that the ring rail has risen to lift the bobbin off its spindle 24.
  • the container into which the doffed bobbins fall is in the form of a chute 49 with a tiltable wall 50 which is tilted out by the air cylinder 51.
  • the actuation should be sufficiently early before the ring rail is raised to the position where the bobbins are doffed so that the wall 50 is out and thebobbins fall into the chute.
  • a conveyor 52 is started and moves to the left, carrying with it the full bobbins. This operation can be seen readily in FIG. 4, where one of the bobbins is shown and which represents a position shortly after the doffing has taken place.
  • the conveyor runs for a sufficient period of time so that all of the doffed bobbins are carried to the left and fall into a bin.
  • the donning bar is caused to move through an arc as it is held at both ends by a pivoted link 58, which can be seen in FIGS. 1 and 4.
  • a pivoted link 58 which can be seen in FIGS. 1 and 4.
  • the arc causes it to turn through 90
  • pairs of gear segments 59 causes the bar to rotate another 90 so that it swings over above the rings 42, and at this point the empty bobbins fall down through the rings onto the spindles.
  • the movement of the empty bobbins is shown in dashed lines in FIG. 8, but in order not to confuse the drawing the donning bar 53 itself and the linkage to cylinder 66 is shown in full lines in FIG. 8 only in their initial position.
  • the exact angle through which the donning bar 53 is caused to rotate is not critical, but it should be near enough to 180 so that the empty bobbins can fall through the rings 42 onto their spindles 24.
  • the pivoting link 58 and gear segments 52 are also prevent on the other end of the donning bar and ring rail, but this is not shown in the drawings.
  • the donning bar 53 is then swung back to its original position, and this is shown in FIG. 4, where all of the empty bobbins have been dropped onto their spindles with the exception of the bobbin at the extreme left, which, as has been described, has been omitted to show the relative heights of the spindle tip and the bobbin tip.
  • the donning bar is now in its normal running position.
  • Safety switches (not shown), prevent jamming in case empty bobbin sticks crossways in a ring. After rectifying the problem, the operator can then reset the rest of the cycle.
  • the semiautomatic donning mechanism is applicable only to spinning frames and cannot be used on ring twister frames.
  • FIG. 4 shows the position just after the bar 45 has been moved to its winding position.
  • the ring rail then bears down again by operation of the cylinder 35, as described above, and this results in chain 12 of the traversing mechanism becoming slack, as is shown in FIG. 5.
  • FIG. 5 illustrates the situation just as the rewind operation starts.
  • the chain is wound up, and now when the counterweights try to raise the ring rail 2, it is held in the upper position of the first stroke by the chain 12.
  • Air is then turned off from the cylinder 55, and since the spinning frame drive was shut off the first time the ring rail was borne down below the normal operating position so that the projections 47 on the doffing bar 45 could slide under the bottoms of the full bobbins, the whole machine is ready to be restarted by a manual start button, (not shown).
  • the chain 12 could also be rewound manually by a crank 64 which fits over a square nut 65 on the shaft 21.
  • This manual rewind is standard in spinning frames: utilizing manual doffing and the power actuated rewind is, therefore, optional as the principal advantages of the present invention are obtainable even with manual rewinding.
  • the cylinder 55 is very small and of low cost as it only has to rewind the chain when it is already slack, and therefore it is preferred to include it.
  • the power rewinding has an additional advantage as it is always a complete rewinding, whereas manual rewinding could carelessly be incomplete. Incomplete rewinding will result in bad bunches and bad bobbin builds, and the complete elimination of this possibility makes the power actuated rewinding normally well worthwhile.
  • the present invention can be applied to existing spinning frames designed for manual doffing.
  • the additional elements such as the doffing bar, rewind, chute wall actuation, and the like, are all easily added without requiring extensive dismantling of any parts of the spinning frame.
  • This is a practical advantage where the invention is to be applied to existing frames, of which there are a very large number used in the industry, but of course it is not necessary to have the additional elements bolted on.
