Definitions

  • This patent application relates to the field cf systems or plants for treating yarn skeins or hanks.
  • Some skein yarns are subjected to a mercerization process in a mercerizing machine; therein each series of skeins is supported on two cylinders having axes parallel to each other and, at skeing loading and unloading position, a cylinder is arranged over the other, the horizontal axes of the cylinders lying in a vertical plane.
  • the most widely used way for skein loading in a mercerizing machine is a manual way, using a cylindrical arm mounting or support and a pair of concave blades for matching the surfaces of said cylindrical arms.
  • An operator presets a lade on a cylindrical arm; then draws the skeins to be processed from a store or container and positions such skeins on the blade, so that the hanks may bear on the convex portion of the blaae (in turn bearing on the cylindrical arm) and dependent therefrom.
  • a second blade is introduced into and bearing on the bottom of the dependent skeins and the second blade is arranged facing the first blade, that is with its concavity facing the first blade.
  • the operator has to displace and rotate the mounting or support to align the cylindrical arm with the upper cylinder of a pair of cylinders of a mecerizing machine. Then, by means of the blades, the operator moves the skeins from the cylindrical supporting arm to the cylinders of the mercerizing machine and then withdraws the blades, one at a time, generally causing them to rotate a few degrees about their longitudinal axes.
  • the operator slips the blades between the cylinders of the mercerizing machine and the skeins. This is a particularly long and complex operation, since at this time the inner threads of the skeins stick onto the mercerizing machine cylinder, are entangled in the space between one cylinder and the other and have to be manually cisplaced.
  • the operator shall withdraw the same with the skeins thereon from the mercer izing machine cylinders and, completely carrying the weight thereof (about 12 kg) has to arrange the same on dyeing sticks and position the latter in the dyeing cabinet at a height of about 2 meters.
  • the apparatus substantially comprises an arm including two skein gripping elements, said elements being elongated and having the longitudinal axes substantially parallel and vertically positioned on one another, each element being rotatable about its own longitudinal axis ana longitudinally movable therealong, at least one element being a concave blade; rotation means for rotating said elements about the respective longitudinal axes, and movement means for moving said elements along the respective longitudinal axes.
  • the elements are a pair of elongate concave blades with axes parallel to each other and vertically arranged one above each other, each blade rotatable about a longitudinal axis.
  • a carriage carries said blades and is movable parallel to the axis thereof, and means are provided to vary the aistance between said blades to tension said skeins.
  • Said carriage is movable along a crosspiece cantilever extended from a supporting structure and the arm, comprising the croosspiece, carriage and blades, is rotatable about a vertical axis. The rotation about the vertical axis is provided by supporting the arm on a rotatable vertical shaft.
  • the rotatable vertical shaft carries two cantilever arms generally rigidly located at 90° from each other.
  • each blade is preferably rctatable about its own horizontal axis through 180° to pass from an "open" condition, in which the blades have the concavities facing one another, to a "closed” condition, in which the blades have the convexities facing one another.
  • the arms are also movable according to a direction substantially transversely of the axes of the mercer- ing machine cylinders.
  • the blades are of rounded tapered shape at the distal end thereof and, as seen in cross- sectional view, have a regular semi-polygonal configuration.
  • an apparatus for handling of skeins includes an arm extended parallel to the axis of the mercerizing machine cylinders, said arm comprising an elongate concave blade and a red parallel to the blade, said blade and red being each rotatable about an axis and said axes being parallel to each other, the blade and rod being also movable along said axes.
  • At least the cuter surface of the blade and the entire surface of the rod are coated with antifriction material.
  • An apparatus allows to carry out with minimum use of labour and fatigue the operation of skein loading on the cylinders in a mercerizing machine and skein unloading therefrom. It also allows automatic slipping of the skeins so loaded on the sticks of a dyeing apparatus. Moreover, an apparatus of this invention provides for said operations avoiding tangles for the yarn, both when the latter is placed on the cylinders of the mercerizing machines and when transferred of the sticks of the dyeing cabinet.
  • An apparatus 10 comprises on a fixed base 12 a fixed upright 14.
  • this upright carries a shaft 20 having a vertical axis, which may be of any desired length.
  • Said shaft 2C is rotatable about its own vertical axis through an arc of about 90° and the rotation thereof is caused by a device 22, to be further explained in the following.
  • the shaft 20 has integral therewith a support 24 (thus rotating with the shaft), which carries two cantilever arms, respectively indicated as a whole at 26 and 28, arranged at 90° from each other, as shown in the horizontal sectional view of Fig. 5.
  • This arm 26 includes an upper crosspiece 30, generally comprising two C-sections 31 and 32, opposite and secured to each other by plates 33.
  • the crosspiece is also supported by a tie rod 34.
  • the C-sections form runways for a carriage 40 driven along the crosspiece 30 by means of a continuous chain 42 extended between two gear wheels 43 and 44 on the crosspiece 30, the chain being driven by a motor 45.
  • the carriage 40 carries a pair of skein gripping or holding elements in the form of longitudinal elongated blades 47 and 48 with axes parallel to each other.
  • each blade is of concave or convex shape and, in the arrangement of Fig. 1, the blades have the concavities facing each other at a position referred to as "open" position.
  • Each blade is supported on the carriage to rotate about its own longitudinal axis through an arc of about 180°.
  • the rotation of each blade about its own longitudinal axis is provided by any known means, such as fluid means 50 and 51.
  • the upper blade 47 is substantially fixed in height on the carriage 40, except for adjustment displacements for accomodation to the mercerizing machine cylinders.
  • the blade 48 is vertically movable for a length, under control of a means indicated at 52, generally a cylinder-piston unit.
  • Fig. 1 also shows a mercerizing machine schematically drawn and indicated at 60, of which two parallel cylinders are shown at 61 and 62.
  • the figure also shows two coupled stiks 63 and 64 for a dyeing cabinet.

  • Figs. 5 and 6 show how each carriage 40 is supported and moved along the respective crosspiece 30.
  • said carriage 40 Rotatably supported on its own casing 78, said carriage 40 has four rollers or wheels 80 running on the bottom area of said C-section 31 and 32.
  • the ends of the feeding chain 42 are secured to the casing at 81 and 82 and for said chain, in Fig. 5,there is shown the gear wheel 44 integral with the further gear wheel 84, driven through chain 85 by the motor 45, carried on the crosspiece 30, for movement to and away from the shaft 20.
  • Fig. 6 also shows the blades 47 and 48, each of which preferably formed by a sheet or plate bent to polygonal shape as seen in cross-section (Fig. 3). Each blade is integral with a spindle 87, 88.
  • said carriage 40 comprises vertical guides 91 and 92, having engaging thereon rollers 94 of a slide 95, on which the spindle 88 of the lower blade is rotatably carried.
  • the slide 95 upward and downward moves along the carriage 40 under control of the cylinder piston unit 52 shown in Figs. 1 and 7.
  • the upper blade is rotatably carried on a plate 98 of the carriage, which is adjustable in height by pins and slots, but, once adjusted, remains substantially fixed or stationary through the machine work cycle. The operation of the machine will be briefly described.
  • an operator places a series of skeins H to be mercerized on the preferably "closed" blades of arm 28 (loading arm in station A).
  • arm 30 independently carries out the unloading operations at B of a series of mercerized skeins, as better understood from the following reading.
  • the blades are opened by a control and the rotation is caused for the arms through 90° about the vertical axis 70. Arm 28 then moves to position B and arm 30 to position C.
  • the opening rotation is caused for the blades, which thereby take the skeins M thereon.
  • the carriage 40 is then moved back and the blades are moved away from each other by the cylincer 52, simultaneously with rotation of arm 26 from station B to station C.
  • the skeins are under tension and without having loose or entagled threads inside. Thus, they can be readily slipped on the sticks 63 and 64.
  • Fig. 9 shows a variant of the apparatus.
  • the machine 10a comprises arms 26a and 28a, each including a carriage 40a longitudinally sliding along the arm and identical to the above described carriages 40.
