Definitions

  • This invention relates to winding apparatus with automatic bobbin-change and conveyer arrangement delivering full bobbins to a removable bobbin magazine.
  • the winding apparatus is associated with an individual conveyer arrangement including a slide member automatically moving according to the operating rhythm of the apparatus and carrying a tilting bobbin catcher, the working stroke of the slide member and bobbin catcher being determined in cooperation with tr e bottom or the bobbin content of the individual magazine associated with the winding apparatus, for delivering the bobbin owing to tilting movement of the bobbin catcher so that the bobbin rolls oil in transverse direction from the bobbin catcher which latter subsequently is returned by said slide member into its initial bobbin receiving position.
  • the arrangement according to the invention permits a neat, regular stacking of Weft bobbins in any number of superposed rows in bobbin magazines, and in such manner, that the bobbins in the respective magazine automatically become aligned with respect to the base of the bobbin, and Without any danger of damaging the package as a result of the bobbins falling down freely at some point of the conveying path, as is the case in convention al bobbin delivering devices, which danger naturally increases with increased fineness of the yarn wound on the bobbin.
  • each apparatus may operate with material individual with respect to its quality, be it with respect to the number of the yarn or to the color of it or to both; accordingly the individual bobbin magazine is supplied only with bobbins carrying yarn of the same quality.
  • This fact, as well as the mentioned regular stacking of the bobbins in aligned superposed rows in each individual magazine constitutes a corresponding simplification of the subsequent handling of the bobbins before and upon their insertion into the weft shuttles, making superfluous any preceding manual work of assorting the bobbins.
  • the movement of the slide may be elfected from a starting or bobbin receiving position and back to same by means of an endless conveyer member serving for temporarily supporting the slide, which member is temporarily and automatically connected in timed relation with a drive element.
  • Fig. l is a fragmentary side elevation of a winding apparatus according to the invention, partly shown in section, the associated conveyer arrangement being drawn in position of rest,
  • Fig. 2 is a View similar to Fig. l, but after the bobbin catcher has received a bobbin and the conveyer has been set in motion,
  • Fig. 3 shows the conveyer arrangement drawn to a larger scale and in the position of rest
  • FIG. 6 shows in elevation and partly in section a group of winding apparatus arranged in line upon a common frame, there being represented four dilferent positions of operation of the apparatus.
  • the Winding apparatus A has a circular rotary body vll, which is supported by means of a central shaft 2 on the casing of the apparatus and carries three circumferentially and uniformly spaced, Winding spindles 3, each of which being destined to receive a winding bobbin B, .for which purpose the spindles are .formed with a bobbin retaining base 3a.
  • the rotary body 1 is turned by means of an intermittently operating driving device (not shown) known per se, to bring one bobbin B after the other to a working station where the respective winding spindle 3 is automatically coupled in conventional manner with a drive spindle (not shown), which for this reason is axially movable in the casing of the apparatus.
  • a guide 4 secured to the casing .of the apparatus carries an ejector 5, which in known manner is automatically reciprocated with a predetermined stroke along .said guide 4 according to the operating rhythm of the winding apparatus.
  • the top part .of the ejector .5 is formed as laterally projecting bobbin holder 5a, which as shown in Fig. 1 may be pushed with circumferential clearance over a full bobbin B1, upon being shifted in the direction towards the case of the apparatus, which bobbin, owing to a turning movement of the rotary bodyl, has been brought into corresponding bobbin change position.
  • the ejector 5 When being subsequently shifted in a direction opposite to that before mentioned, the ejector 5 lifts the bobbin B1 off the spindle in a known manner, in order to release it at the end of the stroke, whereupon the bobbin B1 drops down into an oblong bobbin catcher or catching cradle 6.
  • the cradle 6 (Fig. 6) is mounted with one longitudinal edge thereof for tilting movement on a rod '7 having a front plate 8, which at its end opposite the rod 7 is formed with a transversely directed abutmentSa ('Fig. 6), against which the cradle 6 normally bears.
  • a triangular feeler 9 At the underside of the cradle 6 a triangular feeler 9 is suspended in the manner of a pendulum from an angle piece 10 by means of a fastening hook; in normal position of the feeler 9, one triangular side thereof is situated below.
  • FIG. 11 designates an upstanding box of square cross section, having its wall 12 remote from the casing of the apparatus provided with a vertical slot 12a (Fig. 6).
  • a guide rod 13 disposed in the 'box 11 faces the slot 12a; the removably arranged box wall 12'is omitted in Figs. 3-5.
  • a slide 14' is arranged on the guide rod 13 and the slot 12a assists in guiding the slide 14, since the latter projects through this slot 12a out of the box wall 12.
  • the slide 14 has an outer bent-off arm 14a, from which extends an upwardly protruding arm 14b carrying on the top an extension formed by the rod 7 and the front plate 8 (Fig. l and Fig. 6).
  • the arm 14a of the slide 14 carries an abutment roll 15 for coaction with a control armio.
  • This control arm 16 is mounted on an axle 17 carried by a bearing sleeve 18 of the box 11 (Fig. 6); a link 19 is mounted on the portion of the axle '17 extending into the box 11; this link 19, together with the mentioned control arm 16 thus forms a bell crank control lever.
  • the upwardly directed arm 16 of the control lever 16, 17, 19 is connected by means of a chain 20 and a tension spring 21 with the bobbin ejector 5.
  • the link 19 of the control lever carries a lateral abutment roll 22 (Fig. 5) coacting with a locking lever '23 having two locking notches 23a and 23b.
  • the locking lever 23 is journalled on a bolt 24 fixed to the box 11 and loaded by a tension spring 25, which holds the locking lever 23 in engagement. with the abutment roll 22 of the control arm 19. According to Figs. 1 and 3 this abutment roll 22 is in engagement with the lower notch 23a of the locking lever 23, whereby the control lever 16, 17, 19 is maintained in the position of rest.
  • 26 is an endless chain, which travels over lower and upper sprocket wheels 28, each journalled on a bolt 27.
  • the upperbearing bolt 27 is rigidly secured to the box 11, while the lower bolt 27 is carried by the locking lever 23 and, moreover, supports a gear wheel 30 rigidly connected with the lower sprocket wheel 28.
  • the latter is destined for temporary cooperation with a drive wheel 32 mounted on a shaft 31.
  • the shaft 31 is journalled on a bracket of frame 33, to which the box 11 is attached.
  • the drive wheel 30 Upon operation of the winding apparatus the drive wheel 30 is continuously rotated by the driving mechanism of the apparatus, including a chain drive 34 (see arrow in Figs. 1, 2).
  • the gear wheel 30 journalled on the lever can be brought into or out of engagement with the drive wheel 32 (see Figs. 2 and 4, or 1 and 3) for the purpose of temporarily driving the endless chain 26, serving as conveyer member for the slide 14; in reality, when the gear wheel 30 is disengaged, the side of the conveyer chain 26, located at the left with reference to Figs. 1 and 3 is loose, in order to enable the gear wheel 30 (see arrow in Fig. 3) to be swung into mesh with gear wheel 32 by means of the locking lever 23.
  • a retaining pawl 30a journalled on the lever 23 is in engagement with the gear wheel 30, which pawl prevents a backward rotation of the wheel 39, so that the conveyer chain 26 can be moved only in the direction indicated by arrows.
  • the conveyer chain 26 carries a laterally projecting abutment bolt 35 which serves for cooperation with the slide 14.
  • the frame 33 has secured thereto a supporting board 36 which according to Fig. 6 extends over the length of four winding apparatus A I to IV arranged along the same longitudinal side of the frame 33 and having a common motor drive, so that a single winding machine having a plurality of winding apparatus as described is formed.
  • the supporting board 36 serves for the reception of as many bobbin magazines 37 as winders A are provided; a magazine 37 is arranged on the supporting board 36 in proximity of each winder A, to which magazine the full bobbins from the corresponding winding apparatus A are to be individually delivered by means of the described conveyer arrangement.
  • the magazines 37 of uniform construction are open towards the top and also at the side facing the casing of the apparatus.
  • the winders are associated each with its own magazine, just as many yarns, diifering with respect to quality from each other, may be simultaneously wound on the machine, each kind of yarn being delivered to its particular magazine by means of which the weft bobbins ready for use are kept in storage or, when required, are brought to the weaving loom.
  • the magazine 37 is open at one side adjacent one end of the collected bobbins, the space requirement of the magazine 37 can be reduced to a minimum, while on the other hand the delivery of the bobbins is facilitated and also the removal of same for use.
  • the bobbin B1 removed by the ejector from a single winding apparatus A, is deposited on the corresponding cradle 6.
  • the bobbin B1 dropping from the bobbin holder 5a, thus falls only for a short distance in order to arrive at the cradle 6 of arc-shaped cross section; the position 'of the bobbin B1 in the cradle 6 is in so far predetermined as the base of the bobbin,
  • the freely suspended feeler 9 situated lower than the extension 7, 8 hits a sufficiently solid resistance, be it the bottom of the magazine 37 or (as indicated by dot and dash-lines in Fig. 2) at least one bobbin B2 previously placed into the magazine 37, then the tilting movement of the cradle 6 about the rod 7 is initiated, as it is assumed in Fig. 6 for the magazine 37 of the winding apparatus A III; an abutment may be provided for limiting the tilting movement of the cradle 6.
  • the bobbin B1 carried by it rolls down in transverse direction over the path offered to it by the cradle bottom, in order to assume in the shortest way its place in the magazine 37, as will be readily understood; the bobbins placed in the magazine 37, as already mentioned, are designated by B2.
  • the delivered bobbins B2 will automatically be placed in the magazine 37 side by side and one upon another, so that neatly stacked layers of bobbins are produced, all bobbins facing with their base (provided in known mannor with metal rings) toward the open side of the magazine 37, as Figs. 1 and 2 demonstrate.
  • the bobbin winding will come in contact with metal parts.
  • the extension 7, 8 carrying the cradle 6, while the slide 14 continues its downward movement also will strike against solid resistance ofiered in the magazine 37, as it will be readily understood from the preceding explanations. Then the extension 7, 8 and the cradle 6 cannot be lowered any further, so that the slide 14 is stopped in its downward movement; on the other hand the abutment bolt 35 provided for the slide 14 travels further with the conveying chain 26, in order to move upwardly after having terminated its descending stroke, and having passed around the lower guiding wheel 28 of the conveyor chain 26. Upon its upward stroke the abutment bolt 35 of the conveyer chain 26 strikes from below against the slide 14, which is then taken along and thus moved upwardly again.
  • bobbin conveyor arrangement may also be constructed diiferently than shown in the drawings.
  • a bobbin magazine a conveyer arrangement for delivering full bobbins to said bobbin magazine, said conveyer arrangement including a slide member adapted to automatically move in accordance with the operating rhythm of the apparatus, a bobbin catcher tiltably carried by said slide member, means for determining the working stroke of said slide member and bobbin catcher in cooperation with the bobbin content of said bobbin magazine, means for producing a tilting movement of said bobbin catcher at the end of the working stroke of the slide member to cause a bobbin carried by said bobbin catcher to transversely roll off therefrom into the magazine, and means for subsequently returning the bobbin catcher with said slide member to its initial bobbin receiving position.
  • a bobbin magazine a conveyor arrangement for delivering full bobbins to said bobbin magazine, said conveyer arrangement including an endless conveyer member, driving means for said conveyer member, means for temporarily coupling said driving means to the conveyer member, a slide member connected to said endless conveyer member for temporary movement therewith, a bobbin catcher tiltably carried by said slide member, means for determining the working stroke of said slide member and bobbin catcher in cooperation with the bobbin content of said magazine, means for producing a tilting movement of said bobbin catcher when said slide member is approaching the end of its working stroke to cause a bobbin carried by the bobbin catcher to transversely roll off therefrom into the magazine, and means for subsequently returning the bobbin catcher with said slide member to its initial bobbin receiving position.
  • Winding apparatus according to claim 2, wherein said endless conveyer member is provided with a laterally projecting abutment adapted to support said slide member and to temporarily move said slide member along with the conveyer member.
  • said conveyer arrangement includes upper and lower guide wheels for said endless conveyer member, said conveyer member being provided with a laterally projecting abutment adapted to support said slide member and to move said slide member along with the conveyer member, said abutment being situated below the top of said upper guide wheel when said bobbin catcher is at rest in its initial bobbin receiving position.
  • said conveyer arrangement includes upper and lower guide wheels for said endless conveyer member, a pivotally mounted locking lever, a transmission wheel journalled on said lever for transmitting driving movement to said lower guide wheel, a stationary drive wheel, a control lever coacting with said locking lever to move said transmission wheel in and out of engagement with said drive wheel, said slide member cooperating with the control lever to bring said lever into a position causing the locking lever to move said transmisson wheel out of engagement with said drive wheel and to render the conveyer arrangement inoperative.
