Definitions

  • the thread guiding traverse element has an arcuately elongated shoe adapted to ride the spiral grooves of a rotatable roller and a platelet form slide plate which is guided between two rails running in traverse direction, characterized in that the platelet form slide piece, in a manner known in itself, engages in two parallel guide grooves running in traverse direction and is swingable in these about its vertical axis.
  • INTRODUCTION Devices for the guiding back and forth of a thread, a wire or the like in spooling or winding machines are known in themselves. They consist, as a rule, of a thread or wire traversing element which is reciprocated by a roller, shoe follower, etc. riding in spiral grooves of a roller or drum rotating about its longitudinal axis.
  • the known traversing elements further have a slide piece which is slidable between or on two opposed rails extending in traversing direction or in opposed grooves in these guide rails.
  • a thread or wire guide usually in the form of a small plate, which has a slit or an eye moving the thread or wire back and forth across the winding as the thread or wire runs through the slit or eye.
  • the roller or drum cylindrical surface has two spiral grooves of opposite hand and are connected at their ends generally by an arcuate curve. If the roller or drum. has to execute more than one revolution for one back-andforth movement of the traversing element, there is one or more crossing points of the two grooves, through which the groove-follower of the traversing element has to move smoothly and without unintended changes of direction in the operation of the device. In order to achieve this, it is a known practice to elongate the follower portion which engages in the spiral grooves sufiiciently to assure its desired, smooth movement through the spiral grooves, especially at the groove crossings.
  • the elongated form of the follower is for the sure crossing of the crossing points of the spiral grooves, the difliculty nevertheless arises in guiding the follower from one spiral groove into the other at the reversal zones of the path of travel of the follower.
  • the follower in changing from one spiral groove into the other groove of opposite hand, changes its angular position at the reversal zones.
  • Such joint makes it impossible to reduce appreciably the dimensions and mass of the traverse element. The latter are desirable, particularly at higher traverse speeds and the follower rotati-on speeds at the stroke reversal zones.
  • the traverse element of the Swiss patent has between the follower part in engagement with the spiral groove and the slide piece sliding between the guide rails an intermediate piece which fits exactly into the interspace between guide rails and a cam roller and which lies tangentially on the surface of the cam roller.
  • an intermediate piece which fits exactly into the interspace between guide rails and a cam roller and which lies tangentially on the surface of the cam roller.
  • the plateletform slide piece is just as large as possible within the limits dictated by the groove dimensions. This is achieved (a) where the outer contour of the slide piece is bounded by two parallel pairs of sides whose distance spacing is at most equal to the spatial distance between the two groove bottoms and (b) where the two parallel pairs of sides cross their respective parallel lines at an angle which is equal to the requisite swinging or pivot angle of the slide piece, and (c) where the normally obliquely angular corners of the resulting rhombus are rounded oif with a circular arc whose diameter is equal to the distance between parallel sides of one of the two parallel pairs of sides.
  • the guide grooves of the traverse devices herein can be formed in different ways. It is possible, for example, to cut the grooves in a pair of spaced, suitably dimensioned strips extending longitudinally in the direction of traverse or to compose each strip of several superposed strips.
  • the grooves may also be formed or cut in opposing sides of an elongated slot in a longitudinally slotted plate or the like.
  • a suitable, elongated recess may be provided in each side of the slot of a longitudinally slotted plate which is covered by a likewise longitudinally slotted cover plate of suitable form. Which of the means is chosen in a particular case depends primarily on factors of economy and manufacturing technology.
  • the facing side walls of the slot formed by or in the opposed strips, the slotted plate or the like are spaced to serve as slide surfaces by lying directly against opposite sides of the neck or body of the traverse element. In this manner a further sliding guidance (as an adjunct to or substitute for the guiding structures mentioned earlier) is attained, with virtually no lateral movement in the slot.
  • the traverse element can be desirable to guide the traverse element additionally in the zones of the reciprocation reversal in order to resist the high inertia forces and tipping moment which act on the platelet in these zones.
  • Such an additional guidance can be achieved if the guide grooves in the reversal zones cross over into one another and connect the opposed, longitudinal slots at their ends.
  • the contour of the grooves bottom wall, at least in the reversal zone lies outside the parameter described by the platelet contour.
  • FIG. 1 is an exploded side view of a slide piece embodiment and fragment of a slotted strip with a fragment of the spirally grooved roller;
  • FIG. 2 is a top plan view of the slide piece and fragments of opposed, slotted guide strips
  • FIG. 3 is a top, fragmentary plan view of an embodi ment with a connecting cross groove at the reversal zone.
  • FIG.- 1 makes evident the simple and expedient construction of the traverse element according to the invention.
  • the preferably elongated follower 1 rides in the spiral guide grooves 20 and 21 of a roller 22.
  • the traverse element further comprises the narrow neck 2, the slide piece 3 of generally rhomboidal configuration as viewed in plan, and the thread or wire-engaging element 4all preferably made as a unitary structure.
  • the slide piece 3 rides in opposed, parallel guide grooves 5 and 5' extending in the traverse direction. In the illustrated embodiment, they are cut in opposing faces of two parallel rails 6 and 6'.
  • the guide grooves can also be provided in other ways, for example, by laminated or superposed individual strips, of which the middle one is correspondingly set back.
  • the outer contour of the platelet-form slide piece 3 represented by way of example has two parallel pairs of sides 8, 8' and 9, 9', the spacing of which is at most equal to the distance between the two groove bottom walls 10 and 10'.
  • the parallel pairs of sides 8, 8 and 9, 9' cross each other at an angle which is equal to the pivot angle of the slide piece, which angle in turn is dictated by the angular relationship of the spiral grooves 20 and 21 in roller 22.
  • the sides 8 and 8 or 9 and 9' of the slide plate 3 slide snugly against the groove bottoms 10 and 10' whereby the traverse element is surely guided by these on the entire rectilinear portion of the traverse path.
  • the oblique corners 11 and 11 of the slide plate 3 are rounded off with a circular arc whose diameter is equal to the distance between the parallel pairs of sides 8 and 8' or 9 and 9'.
  • FIG. 3 there is represented at the zone of the reciprocation reversal a construction capable of sure functioning and the extended life of the traverse element according to the invention.
  • the illustrated embodiment makes use of a cross groove 12 connecting the ends of guide grooves 5 and 5' in the zone of the reversal of the traverse element.
  • the grooves 5, 5' and 12 in this case are milled in the edges of a longitudinal slot 14 in a unitary plate 13.
  • the neck piece 2 of the traverse element extends and slides against the sides of slot 14, which ends as 15.
  • the traverse element rushing in the direction of the end 15, is oriented as shown at 16 in FIG. 3.
  • the element pivots about its vertical axis 7 and, at the reversal point, assumes the orientation at 17.
  • the slide piece 3 will not be hampered in carrying out this pivotal movement by the bottom wall of connecting groove 12, this wall, at least in the zone of linear reversal, is contoured so that the groove bottom wall 10 lies beyond the swinging are 19 of the end of the plate 3 as the latter pivots.
  • a traverse mechanism for reciprocating a thread or wire in a spooling machine which comprises a pair of elongated, parallel guide members with respective, opposed, parallel, elongated grooves, and a thread or wire guide traverse element slidably mounted on and between said guide members, said traverse element having (a) a thread or wire-receiving member at one end thereof, (b) an elongated follower at the other end thereof adapted to ride in spiral grooves of opposite hand in a drive roller which is adapted to impart reciprocating movement to said traverse element, and (c) an intermediary platelet member having the edge portions thereof slidably and pivotably received in said opposed grooves in close fit.
  • said platelet member having two pairs of parallel, opposite sides, the distance between respective sides of each pair being substantially the same as the distance between bottom walls of said opposed grooves, the angle between respective sides of said pairs of sides being equal to the angle of pivot of said element when said linear direction of travel is reversed, and opposite corners of intersection of respective sides of each pair being rounded off in a circular arc, whereby said traverse element is guided in its linear travel by said grooves and can pivot about an axis substantially at right angles to said platelet member when the direction of linear travel of said element is reversed with said platelet member stabilizing said traverse element against tipping.
  • a traverse mechanism for reciprocating a thread or wire in a spooling machine which comprises a pair of elongated, parallel guide members with respective, opposed, parallel, elongated grooves, and a thread or Wire guide traverse element slidably mounted on and between said guide members, said traverse element having (a) a thread or wire-receiving member at one end thereof, (b) an elongated follower at the other end thereof adapted to ride in spiral grooves of opposite hand in a drive roller which is adapted to impart reciprocating movement to said traverse element, and (c) an intermediary platelet member having the edge portions thereof slidably and pivotably received in said opposed grooves whereby said traverse element is guided in its linear travel by said grooves and can pivot about an axis substantially at right angles to said platelet member when the direction of linear travel of said element is reversed, said element having a neck between said platelet member and said follower and a body portion between said platelet member and said thread guide, and said guide members having opposed, parallel faces
