Definitions

  • ABSTRACT A yarn guideand monitoring apparatus at a bobbin or warpers creel, especially at a beam warping creel, comprising a feeler needle which is held against the yarn and upon the occurrence of yarn rupture carries out a pivotal movement into a tilted position, whereby it shuts down the associated yarn processing machine by interrupting a control current circuit.
  • a yarn clamping mechanism formed by two surfaces which can be resiliently pressed or urged against one another.
  • the feeler needle which is pivotably mounted, in the direction of travel of the yarn, behind the yarn clamping mechanism and in a plane perpendicular to the plane of a gap between the surfaces of the yarn clamping mechanism has a substantially U-shaped flexed free end which is located in the aforementioned pivot plane and is subjected to the action of a spring which in the absence of the yarn retains the feeler needle in the aforesaid tilted position.
  • the feeler needle in this rest position of the components bears with its free end against a stationary yarn deflecting pin and renders possible the threading-in or drawing-in of a yarn in one operation into the yarn clamping mechanism and along the deflecting pin and about such into the U- shaped end of the feeler needle.
  • the present invention relates to a new and improved construction of a yarn guideand monitoring apparatus or mechanism at a warpers or bobbin creel, especially at a beam warping creel, incorporating a feeler needle which is retained against the yarn, this feeler needle carrying out a pivotal movement into a tilted position upon rupture of the yarn, whereby such feeler needle shuts down the yarn processing machine by interrupting a control current circuit, and the aforesaid apparatus is also equipped with a yarn clamping device formed bytwo surfaces which can be resiliently pressed against one another.
  • the yarn brake or clamping mechanism only has the function, when the winder is at standstill, to maintain the yarn field under tension so that it can be better visually observed, and additionally, during start-up of the winder to impart to the yarns a certain tension so that the yarn field can so-to-speak untangle or disengage, that is to say, any possible yarns which are coiled or intertwined with one another or adhere to one another can separate.
  • the brake or clamping device is opened and the yarn, without being braked, passes through its yarn guide mechanism.
  • the heretofore known yarn guideand monitoring devices are associated with the drawback that at least some of them have considerable yarn wrap angles and- /or excessive deflections, leading to undesired bending loads or stresses at the yarn and to increased formation ofdust. Furthermore, as a result there is rendered more difficult a low tension or tension-poor processing operation. Also, these prior art mechanisms are generally complicated in construction and in their mounting and are accessible with difficulty for cleaning purposes.
  • Another object of this invention aims at the provision of an improved construction of apparatus of the previously mentioned type which avoids these drawbacks, particularly the last above-mentioned drawbacks.
  • the apparatus of this development is manifested by the features that the feeler needle which, in the direction of travel of the yarn, is arranged behind the yarn clamping mechanism and is pivotably mounted in a plane perpendicular to the plane of a gap between the surfaces of the yarn clamping mechanism has a substantially U-shaped flexed free end which is located in the aforementioned pivot plane and is subjected to the action of a spring BRIEF DESCRIPTION OF THE DRAWINGS
  • the invention will be better understood and objects other than those set forth above, will become apparent when consideration is given to the following detailed description thereof wherein the drawings show, purely by way of example, an embodiment of yarn guideand monitoring apparatus at a beam warping installation with a ⁇ ficreel. Such description makes reference to the annexed drawings wherein:
  • FIG. 1 schematically illustrates a top plan view of a beam warping installation
  • FIG. 2 is an enlarged view of a detail or section of the installation depicted in FIG. 1;
  • FIG. 3 is a partial view of a rail with two yarn guideand monitoring apparatuses or devices in different operating positions;
  • FIG. 4 is a view corresponding to that of FIG. 3 of a yarn guideand monitoring apparatus with removed cover portions;
  • FIG. 5 is a cross-sectional view of the arrangement of FIG. 4, taken substantially along the line V-V thereof.
  • a beam warping machine or installation as schematically depicted by way ofexample in FIG. I, differs from a warping machine or frame in that in the case of the beam warping installation the yarns or threads are directly wound-up in their full width, in other words not bandwise, at the warp beam K of the winding machine W.
  • the machine or installation depicted by way of example in FIG. 1 operates with a V-shaped creel. With such type creel the bobbins or spools S (FIG.
  • yarns or threads F hereinafter simply referred to as yarns, paid-off the bobbins S located in the work position, each individually pass through a yarn guideand monitoring mechanism 7 and from such location arrive directly, i.e., without any further guide elements, at the comb of the winding machine W.
  • creel An essential advantage of such creel resides in the fact that the bobbins, during the warping process, can be newly mounted or creeled, and that after there has occurred the depletion of the bobbins, such can be collectively exchanged at one time in that the depleted bobbins are transported by means of the chain R out of their work position.
  • the bobbins-or spools are arranged above one an-- other at supports in the creel.
  • the individual mechanisms 7 for guiding and monitoring the yarns F from the bobbins S, which form a vertical row in the creel, are accommodated at a vertical substantially U-shaped profile member or portion 2 of the creel.
  • Two contact rails 5 and 6 extend over the entire length of the profile member 2, parallel to its web 3 and such rails are insulated or isolated from the profile portion by the holder 4.
  • Each mechanism 7 is assembled or mounted as a fabricated component by means of two screws (not shown) or equivalent fastening expedients, which can be threaded into threaded holes or bores of the holder 4.
  • a plastic body or body member 8 which fits into the opening of the profile member 2 and serves as a carrier and housing for all further components of a yarn guideand monitoring mechanism 7.
  • a metallic profile rod member 9 At the plastic body 8 there is threaded at one side or laterally thereof a metallic profile rod member 9, as best seen by referring to FlG. 5, and which profile rod member protrudes slightly past the plane of one leg of the profile member or portion 2 and possesses a flat or planar polished surface 10 parallel to such plane.
  • this surface 10 there is located a likewise flat or planar surface ll of a double-angled or flexetl portion or componcnt 12 which owing to its sensitivity is constructed as a lightweight member and in which there is secured a A rail 15 (FIG.
  • This yarn clamping mechanism viewed in the direction of travel of the yarn, has arranged upstream thereof a feeler or sensor needle 20.
  • This feeler needle v20 is rigidly connected for rotation with the end of a shaft or axle 21 which protrudes from the profile member'or part 2, this shaft 21 being mounted at the body 8 parallel to a gap 17 between the surfaces 10, 11 of the yarn clamping mechanism, so that the feeler needle 20 is pivotable in a plane perpendicular to the plane of the aforementioned gap 17 in front of such gap.
  • a sleeve 22 rigidly rotatably connected with the shaft 21 eccentrically supports an arm 23 at which there is secured the'one end ofa weak tension spring 24.
  • the other end of the tension spring 24 is stationarily or fixedly secured to a contact plate 25 and the body 8. This one end of the spring 24 is connected via the contact plate 25, an attachment screw 26 and a contact spring 27 electrically conductively with the contact rail 5.
  • the tension spring 24, in the rest position of the components as such has been shown in FIG. 3 for the lower mechanism 7 and with full lines in FIG. 4, presses a cam 28 which protrudes from the sleeve 22 (FIG. 4) against a contact plate 29 of the body 8.
  • the contact plate 29 is electrically conductively connected through the agency of an attachment screw 30 anda contact spring 31 with the contact rail 6.
  • the free end 32 of the feeler needle 20 which is bent in a U-shaped manner so as to be open towards the bottom, bears with its outer leg against a 'yarn deflecting pin 33 which is arranged in the same plane as the feeler needle 20 and which is rigidly connected with its one end in the profile rod member 9.
  • This yarn deflecting pin 33 extends at an inclination from its attachment location downwardly past the gap 17 and terminates flush with the end of the feeler needle 20 in the rest position thereof.
  • a cover plate 34 which can be simultaneously mounted with the body 8 protects the components which have been accommodated in the profile part or member 2 against dust.
  • This cover plate 34 carries a cover member 35 which is visible in FIG. 3 and which also encloses or covers the bearings or supports of the feeler needle 20 and prevents that yarn will become caught at such supports or bearings.
  • a pivotable knife or cutter rail 40 is arranged at the profile member 2, the blade or knife 41 of such cutter or knife rail 40 being pivotable through the action of a central control for all cutter rails at the region of the yarns between the bobbin and the yarn clamping mechanism, in order, prior to a group exchange operation, to simultaneously cut or separate all yarns. After this separation or cutting, it is possible, on the one hand, to remove or move away the empty bobbins and, on the other hand, to thread out the free hanging yarns which are still located at the yarn guide and monitoring mechanisms.
  • the yarns of the bobbins at all of the levels of the creel which are located above one another are grouped together and now in a single manipulation or handgrip can be drawn into the individual yarn guideand monitoring mechanisms in that they are guided from the top towards the bottom along the associated profile memher 2.
  • An aisle or passage 51 which is formed by the bevelled champfered portions 52, 53 ofthe upper ends of the profile rods 9 andthe components 12, during downward movement with the thread, catches a yarnor thread and this yarn, during further downward movement, arrives at the gap 17, is deflected by the deflection or deflecting pin or pin member 33 out ofthe plane of the gap 17 and slides along the pin 17 about the end of the feeler needle 20 and into the bracket-shaped end thereof.
  • the inventive yarn guideand monitoring mechanism or device not only permits of a rapid, positive drawing-in of the yarns, rather, and this constitutes a further quite considerable advantage, such can occur without the clamping mechanism or the feeler needle having to be brought into a particular position, especially into the clamping position of the clamping mechanism, in other words in that position in which the components are located when the winding machine is at standstill, whether such is brought about because of yarn rupture or because of bobbin exchange.
  • the yarn clamping mechanism is only closed during standstill of the winding machine and during start-up thereof.
  • all of the yarn clamping mechanisms are opened into the position shown at the top of FIG. 3.
  • the threading-out of the yarns from the feeler needles during the operation of the machine is prevented towards the top by virtue of the U-shape of the feeler needle end and towards the bottom by the pin 13.
  • each yarn retains its feeler needle 20, against the action of spring 24, in the position shown at the top of FIG. 3, wherein the contact cam 28, as shown in phantom lines in FIG.
  • the inventive yarn guideand monitoring mechanism functions with a comparatively small wrapping angle of 90.
  • This provides less tension control and a very small chafing load or chafing of the yarns.
  • This again renders possible high withdrawal speeds.
  • the small bending loads resulting from the slight deflection of the threads renders it possible to increase the range of the yarn numbers of yarns which are processed at a creel equipped with the inventive 6 mechanism, in particular it is also possible to process coarser yarns.
  • a further advantage of the inventive mechanism also resides in the fact that the yarn clamping mechanism is arranged upstream or ahead of the feeler needle viewed in the direction of travel of the yarn. This sequence has; the advantage that any possible dam-up due to the clamping mechanism does not have any effect upon the needle and cannot lead to erroneous shutdowns, ano that the feeler needle continuously fulfills its function and not merely when the clamping mechanism is released.
  • said feeler needle being arranged behind the yarn clamping mechanism with re spect to the direction of travel of the yarn and being pivotably mounted in a plane perpendicular to the plane of a gap between the surfaces of the yarn clamping mechanism, said feeler needle having a substantially U-shaped flexed free end which is located in said pivot plane, a spring acting upon the feeler needle, which spring in the absence of the yarn retains the feeler needle in said tilted position defining a rest position, a stationary yarn deflecting pin, the feeler needle 7 in this rest position bearing with its freeend against said stationary yarn deflecting pin and rendering possible the threading inof a yarn in one operation into the yarn Clamping mechanism andalong the deflecting pin and i of the feeler needle.
