Definitions

  • ABSTRACT A spooling device for winding a thread package on a rotatable carrier with a pre-winding means to form an initial winding and/or thread reserve at one end of the carrier adjacent the normally wound package, this pre-winding means including a multi-flanged cylindrical thread guide element rotatable into open positions consisting of circumferentially removed portions of the individual flanges which permit the running thread to slide axially along the circumferential threadcontacting surface of the guide element past each flange.
  • a point-like or nearly point-like deposit of the thread demands that the maximum thread length be limited, because otherwise the danger exists that the layers of: the thread reserve or the individual windings willslipwith respect to one another so that the discovery of the endof the thread and/or the taking off of the thread reserve will be made difficult or imlt is also required that the initial winding be at least long enough that no spoiled material comes into the thread reserve lying beside it or into the main winding.
  • its length must be limited in order to avoidunnecessary amounts of waste material and-to make possible a space-saving winding, i.e. one which is point-like or nearly point-like along the carrier, thereby permitting a still very satisfactory unwindingand removal or the thread.
  • Both the initial winding and also the thread reserve can be produced in the form of narrow, high windings.
  • this technique requires a very high technical expenditure, because in addition to the essential traversing device for the production of the mainwinding, one must also provide an additional reciprocating traversing device for the production of the initialwinding and/or the thread reserve.
  • a device has been suggested for the traversing drive of spooling apparatus in the winding and setting of a thread reserve, whereby it is possible to hold the main thread guide at its reversal point until a thread reserve has been formed of apredetermined length.
  • the disadvantage of this device resides in the fact that it requires a proportionately large mechanical expenditure, and that the entire thread reserve isdeposited in a winding with several layers, these layers having a very strong tendency to slide and thereby hide or cover up the beginning of the thread.
  • This known device also has the disadvantage that the traversing thread guide must be put at the reversal point in the starting of the spooling operation and an adjustment of the traversing drive is necessary.
  • Still another object of the invention is to provide a prewinding means whereby an initial winding of waste thread can be followed by a second separate thread reserve winding, both windings being relatively limited in the terminal zone of the thread spool or carrier to a point-like or nearly point-like thread application.
  • said pre-winding means essentially including an elongated cylindrical guide element rotatably mounted and positioned along said carrier terminal zone with the axis of the guide element parallel to the carrier axis so that the thread is received in runningcontact partially around the circumferential surface of said guide element, drive means to rotate said cylindrical guide element, and at least two radially projecting flanges at axially spaced positions on said guide element for rotation therewith, each flange being steeply flanked in the axial directionof the guide element and having at least one segment removed therefrom to provide a corresponding open position of the flange where the thread can slide axially along the circumferential surface of the guide element past the flange.
  • the spooling device preferably has three of the projecting flanges distributed over the length of the guide element, and each flange preferably has two removed segments or open positions opposite one another, i.e. spaced about 180 apart with reference to their rotated positions. Also, the open positions of each individual flange are preferably turned about 90 from the open positions of the adjacent flanges.
  • FIG. 1 is a partly schematic perspective view of a spooling device equipped with the improved prewinding means of the invention including a cylindrical guide element having two flanges;
  • FIG. 2 is a transverse cross-sectional view through the axis of rotation of the guide element adjacent one of its flanges;
  • FIG. 3 is a' perspective view of a modified guide element with three flanges in addition to a collar fastening means.
  • the thread or yarn Y runs from the fixed guide eyelet 17 to be spooled or wound into a conventional package on the carrier or bobbin sleeve 1 over the length of the sleeve represented by the pair of broken lines 2.
  • This conventional thread package is wound with the aide of the traversing guide member 4 which reciprocates in a linear direction parallel to the carrier axis over the length 3 by means of the rod 5 which can also reciprocate with the guide member 4 being fixed thereto.
  • the yoke or guide member 4 can be constructed as a conventional traveler keyed to the rod 5 or a camming means to produce the desired reciprocation for building the main thread package.
  • the position 4' represents the opposite end of the traversing stroke of this reciprocating guide.
  • the carrier 1 is rotated by positive frictional contact with the drive roller 6, althoughother conventional means may also be used for driving the bobbin or car rier.
  • it is desirable to vary the winding speed over the course of the main winding operation eg to achieve a more uniform thread tension or other desirable winding characteristics.
  • initial winding is employed herein with the restricted meaning of the first or starting winding of a length of thread as it. is first brought from a previous operation ontothe spooling device of the invention, often as a length of waste or incompletely processed thread.
  • thread reserve refers, on the other hand, to a length of thread which has been completely processed or which has the same quality as the thread of the main winding, the length of winding in this thread reserve usually being rather short but long enough to permit easy access and tying with another thread end.
  • the initial winding by comparison, may be relatively long and is usually discarded as a waste material.
  • pre-winding is thus intended to be generic to both the initial and thread reserve windings and is distinguished from the main winding or normally wound thread package.
  • the thread Y during the normal winding operation is also guided over the extended shaft and guide rod 7 which in turn is driven by the variable speed motor 8.
  • the thread Y is guided in the path 9 over the cylindrical guide element 10 fixed onto the shaft 7 for rotation therewith.
  • This guide element 10 contains at least two temporary thread barrier means in the form of the projecting flanges l1 and 12 spaced axially of one another as partial annularelements along the circumference of the guide element 10 which is in running contact with the thread 9.
  • Each flange has at least one interruption or removed segment 14 so that the thread is free to slide axially past the flange at one open position of the rotated shaft 7, guide element 10 and flange 11 or 12.
  • the flange 11 has two gaps or removed segments such that the remaining edges 16 on either side of each gap form an angle enclosing the guide element 10 which is preferably only slightly smaller than the enclosing angle of the thread in its guided path 9.
  • the difference in the two angles can be expressed by 2a where a is the angle shown in FIG. 2 between the leading or trailing edge 16 of each annular flange segment and the thread path 9 running onto or off of the guide element 10, respectively, i.e. with this guide element rotated into one of its exact open positions.
  • This angle a may be as small as a fraction of 1 degree up to about preferably from about 1 to 10.
  • the flange 11 in FIG. 2 has two open positions:
  • the thread is brought from eyelet 17 and deposited along the fixed guide rod 15 onto the receiving zone or surface 18 of the cylindrical guide element 10 or 10a, and is then applied or taken up on the sleeve 1, e.g. by means of a thread-catch groove or notch which holds the thread end as winding on the sleeve begins.
  • the thread then travels or migrates along the surface 18 in the direction of the center of the sleeve 1, due to the tension being exerted on the thread, until it pushes up against the side flank of the first flange 11 which can be preset in one of its closed positions or which preferably receives the thread at any point of time in its continuously rotating operation to provide an initial winding or indeterminate length.
  • This first barrier formed by flange 11 is then crossed by the thread at a very specific rotational position. In FIG. 1, the flange 11 has only one such position at which the thread crosses, i.e. a single gap or interrupted portion which in this instance is hidden from view and away from the visible gap 14 of flange 12.
  • the thread Once the thread crosses or slides by the first flange 11, it travels or migrates further axially along the guide element 10 up to the second flange 12 where another temporary barrier is formed until this flange also rotates into its open position to permit the thread to pass over gap 14 as indicated in FIG. 1.
  • the length of thread applied to the carrier sleeve 1 in the terminal zone 21 while the thread runs in the area of the guide element 10 between the two flanges depends upon the linear velocity of the thread itself, the turning speed of the guide element and the arrangement of the gaps or removed segments of the rotating flanges.
  • the thread falls into or becomes engaged in the reciprocating thread guide 4 as shown in FIG. 1, whereby the thread is conventionally wound into a cross bandage package, i.e. cross-laid layers of the main winding.
  • This slotted guide 4 with its reciprocating rod 5 travel so rapidly that the thread emerging axially from guide element 10 will normally pass only a short distance toward the center of the winding before it is positively engaged by the guide 4, i.e. by riding up the slanted arm portion of the yoke-shaped guide.
  • the position of this conventional traversing guide at the beginning of the winding operation is of no importance, and it will engage the thread automatically to begin the main winding almost immediately after the initial or thread reserve winding have been completed near the end of the carrier.
  • the guide rod 7 can continue to function as a guide means for the main winding in addition to its function as a drive shaft for the multi-flanged guide element 10.
  • this shaft 7 can also be a separate guide rod in a fixed position or even in a retractable position, e.g. by means of any practical mounting means.
  • the embodiment of the pre-winding means and spooling device shown in FIG. 1 is especially valuable. however, because it can be installed in a very small space.
  • the cylindrical guide elements 10 and 10a have at least one pair of coplanar, circumferentially spaced flanges 11, 12, 13 projecting circumferentially and radially from opposite sides of the cylindrical guide element.
  • Each flange has a steeply flanked side face 22 forming respective thread restraining shoulders.
  • Each flange has a leading edge 16 and trailing edge 16, said edges lying in respective planes T which are substantially tangential (FIG. 2) with the cylindrical surface of the guide element 10 or 10a.
  • the thread guide means 17 and 4 preceding and following the guide element 10 or 10a guide the thread Y arcuately over and in contact with an arcuate portion of the cylindrical surface of guide element 10 or 10a. As shown in FIG. 2, the thread runs tangentially onto and off the arcuate portion of the cylindrical surface. The are A between the tangential intersections with the cylindrical surface of the respective planes of the leading and trailing edges 16 and 16' of respective flanges is greater than the arc B of said arcuate portion which is contacted by the running thread Y.
  • the pair of flanges 12,12 is circumferentially staggered by 90 relative to the next adjacent pair of flanges 11,11 and 13,13.
  • An angle a of about 1 to 10 is formed between said respective tangential planes of said leading edges and trailing edges of said flanges and the thread running onto and off of said cylindrical surface when the guide element is rotated to a position wherein the thread is not restrained by said steeply flanked faces forming said threadrestraining shoulders (FIG. 2).
  • the invention also permits a very careful handling of the thread while allowing narrow or almost point-like pre-windings where the running thread rests temporarily up against each flange member.
  • all of the individual parts of the spooling device, especially the prewinding means therefor, are very inexpensively constructed and installed.
  • a special advantage of the supplemental or pre-winding guide element with its two or more flanges resides in the fact that it can be produced as a' body of revolution, preferably treated in a conventional manner to provide a hard and wear-resistant surface for contact with the running thread.
  • Other customary features of design and construction of the over-all spooling device are capable of being widely varied and still be adapted for combination with the pre-winding means of this invention.
  • a spooling device for producing a thread package by winding a thread onto a rotating carrier.
  • the improvement of means for pre-winding the thread onto a terminal zone of the carrier axially adjacent the normally wound thread package which comprises:
  • an elongated cylindrical guide element rotatably mounted and positioned along said carrier terminal zone with the axis of the guide element parallel to the carrier axis so that the thread is received in running contact partially around the circumferential surface of said guide element; drive means to rotate said cylindrical guide element;
  • each flange having a steeply flanked side face forming respective thread restraining shoulders, and each flange having a leading edge and a trailing edge which lie in respective planes which are substantially tangential with the cylindrical surface of said guide element, and thread guide means preceding and following said guide element for guiding the thread arcuately over and in contact with an arcuate portion of said cylindrical surface, upon which arcuate portion the thread runs tangentially onto and off said cylindrical surface, and the are between the tangential intersections of respective planes of said leading and trailing edges of respective flanges with said cylindrical surface being greater than the arc of said arcuate portion contacted by said running thread.
  • a spooling device as claimed in claim 1 including three of said pairs of said projecting flanges axially spaced along the length of said guide element.
  • a spooling device as claimed in claim 1 said guide element having at least two of said pairs of flanges, and one pair of flanges being circumferentially staggered by relative to the next adjacent pair of flanges.
  • a spooling device as claimed in claim 1 and further including a thread guide rod projecting along the length of said carrierin a position parallel to the carrier axis.
  • a spooling device as claimed in claim 1 wherein an angle a of about 1 to 10 is formed between said respective tangential planes of said leading edges and trailing edges of said flanges and the thread running onto and off of said cylindrical surface when the guide element is rotated to a position wherein the thread is not restrained by said steeply flanked faces forming said thread-restraining shoulders.
