Definitions

  • the invention relates to a delivery device according to the preamble of claim 1.
  • An advantage of the delivery device is that, while avoiding the stop-and-go mode of operation of the drum, a minimization of the thread take-off tension is achieved and that even with difficultly designed threads, multiple wraps on the drums are possible while largely preventing thread layers from overlapping.
  • the object of the invention is based on the development of a delivery device of the type in question in such a way that an optimization with regard to the mode of operation is achieved.
  • a delivery device of the type in question is specified, which is characterized by an optimal mode of operation.
  • Both the intermediate walls and the ring collar of the drum jacket surface which are flush with them prevent with certainty that in the case of multiple wrapping of the drums, adjacent layers of thread can step over one another. Faults in thread take-off resulting therefrom are accordingly eliminated.
  • the height of the ring collar corresponds at least the thread thickness. A height of a few millimeters is preferably selected so that a wide variety of yarns can be processed with a single delivery device. If one leaves an annular gap between the ring collar and the intermediate wall, the size of which also corresponds at least approximately to the thread size, it is also avoided that thread material can get caught there.
  • the air baffle bar which is approximately radially oriented on the drum shell surface, is also provided. This extends in the circumferential direction just behind the tangent point between the thread and the drum surface.
  • the air baffle creates an air flow that is directed away from the drum and accordingly presses against the thread layers in a way. This prevents the thread from being sucked into the gusset of the drums and from being wound onto one or the other drum.
  • the ring collars support the above-mentioned effect in that the air flow does not emerge sideways on the drums, but acts specifically on the thread layers.
  • Air baffle bar on an arm that can be pivoted towards the center of the drum. This is held by the supporting web of the intermediate walls, so that the supporting web, which is present anyway, performs another function.
  • the arrangement of two diametrically opposed arms with air baffle bars ensures that yarn material cannot be sucked into either the upper or lower gusset formed by the drums.
  • it has the necessary airtightness.
  • it is equipped with the required flexibility.
  • the thread delivery device has a support column 40, in which a drum drive, not shown, is accommodated. Via a drive belt 41, pulleys 42, 43 are rotated in the same direction, which pulleys are firmly connected to a drum 44, 45. With regard to the drums 44, 45, these are free-floating circular cylindrical bodies, the axes of which lie in a common horizontal plane and are arranged such that the drums 44, 45 are provided at a distance from one another. The drums 44, 45 have the same length in such a way that their front, free edges are aligned with one another.
  • a web 46 extends from the support column 40 and runs parallel to the drums and serves to hold intermediate walls 47, 48.
  • the latter are designed in the form of ring disks, the ring openings of which are penetrated by the drums 44 and 45, respectively.
  • the drum jacket surface is provided with radially outwardly directed annular collar R which is aligned with the plane of the intermediate walls 47, 48.
  • the height of each ring collar R is at least as large as the material thickness of the thread F to be processed. In practice, this means that a few millimeters are selected for the height.
  • the aforementioned ring collars R form in connection with the ring openings of the intermediate walls 47, 48 a gap 51 which corresponds at least approximately to the thread diameter. This gap 51 runs concentrically to the ring collar R or to the drum casing wall T.
  • the aforementioned ring collars R are preferably made of the same material as the drum casing wall T.
  • the drum jacket wall T has on one or more drum sections a rib-like elevation 52 running in the axial direction.
  • this is formed by a rod 53 inserted into the drum jacket wall T, the peripheral surface of which protrudes beyond the drum jacket wall T and forms a board there.
  • a rod 53 which is circular in cross section and whose Length corresponds approximately to that of the drums 44, 45. This means that it also passes through the ring collar R of each drum 44, 45. Accordingly, the rod 53 does not protrude beyond the ring collar in the radial direction, but is offset from it in the inward direction.
  • rod sections could also be used which extend between the ring collar R and end at the latter.
  • a cover 54 covering the drums 44, 45 and the intermediate walls 47, 48 is also provided.
  • the latter is U-shaped in cross-section.
  • the web 55 of the U-profile extends in front of the end faces of the drums 44, 45 or the outer intermediate walls 47, 48, while the legs 56, 56 'of the U-profile extend to the outer edge of the intermediate walls 47, 48 and there one Protect the thread from jumping over from one drum area via the intermediate wall into the other drum area.
  • each drum jacket surface of each drum is assigned an approximately radially oriented air baffle 59, 60 such that it lies in the circumferential direction just behind the tangent point between the thread F and the drum jacket surface.
  • Each air baffle bar 59, 60 is seated on an arm 61 or 62 which can be pivoted in the direction of the center of the drums 44, 45.
  • the bearing point for the arm 61, 62 is formed by the supporting web 46 for the intermediate walls 47, 48, compare FIG. 4.
  • the arms 61 , 62 are diametrically opposite directed and designed identically, so that almost the same conditions exist.
  • the arms 61, 62 can be firmly clamped to the supporting web. The swiveling is then only necessary when adjusting the arms.
  • the aforementioned air baffle bars 59, 60 grind on the drum surface and consist of felt of appropriate thickness. Therefore, they can briefly avoid contact with the rib-like elevations 52 in order to then return to the contact position with the drum jacket surface.
  • Each air baffle bar 59, 60 is composed of several short sections, which generally correspond to the distance between the partition walls 47, 48. Therefore, the air baffle bars 59, 60 fill with their sections between the ring collars R and the intermediate walls 47, 48.
  • the thread F After the thread F has been drawn off, it passes through an adjustable thread brake 57 in the direction of the arrow and loops around the drums 44, 45 in the zigzag course shown in FIG. 2. After passing through the partial area g ', the thread F leaves the thread delivery device through a thread eyelet 58.
  • the thread F does not slip.
  • the tension increases while the thread is dragged along.
  • the rod 53 forming the rib-like elevation 52 constantly ventilates the partial wraps of the thread F while avoiding excessive heating thereof, see FIG. 10. From this figure it can be seen that the rib-like increase 52 of the thread from the drum jacket wall T im corresponding area is lifted off.
  • a time-delayed synchronous circuit of the drum drive for driving the associated weaving machine can be assigned to the thread delivery device.
  • the ring collars R prevent the thread from being able to pass from one partial area to another.
  • the partitions 47, 48 and the cover 54 also contribute to this.
  • the air baffle bars 59, 60 generate an air flow when the drums 44, 45 rotate in the direction of the arrow, which air flow is directed out of the gusset, ie away from the drum. This prevents the thread from getting into the gusset of the drums and being unwantedly wound onto one or the other drum.
