Definitions

  • the invention relates to a bobbin tube of cylindrical cardboard filiform material comprising an upper edge, a lower edge a main inner diameter, a main outer diameter and means for retaining the initial section of the filiform material near the bottom edge.
  • Bobbin tubes of filiform material are known for the transport and supply of filiform material, for example for all kinds of threads for the textile industry. These tubes are substantially a circular cylinder. In certain applications the tube must have a constant and through inner diameter since the tube must be housed in an axis that crosses it in its entirety, such as in the continuous spinning of polyester, polyamide or polypropylene. In the present description and claims, this inner diameter has been indicated as the main inner diameter, in the sense that the tube will rest on the shaft and, therefore, must be the minimum inner diameter present inside of the tube.
  • These bobbin tubes comprise means for retaining the initial section of the filiform material, which is usually a through hole that crosses the tube wall and is arranged near one of the ends and / or a reserve line or cut, which extends a certain arc along the outer surface of the tube parallel to the lower edge thereof.
  • These retention means fix the beginning of the filiform element that forms the coil.
  • the lower edge of the edge next to these retention means and the upper edge of the opposite edge have been designated.
  • These bobbin tubes are used by the thread manufacturer to wind the thread so that the coil can then be supplied to the customer. For this, a plurality of coils are stacked in a container or a transport tray. However, to support one coil on the next one, separators that are partially inserted inside the lower tube and that rest on another separator partially inserted in the upper tube must be used. All of this makes it difficult and expensive to stack for transport.
  • the object of the invention is to overcome these drawbacks.
  • This purpose is achieved by means of a bobbin holder tube of the type indicated at the beginning characterized in that it comprises an outer perimeter recess in one of the edges and an inner perimeter recess in the other of the edges, where the lower edge is suitable to fit in the upper edge of a second tube identical to the tube.
  • the tubes rest directly on the previous one, which avoids the need for intermediate supports.
  • On the inner surface of the cylinder an inner perimeter recess is practiced which, therefore, has an inner diameter greater than the main inner diameter and, therefore, does not represent any obstacle for the subsequent mounting of the tube on a through shaft.
  • the interior perimeter recess is made on a small surface compared to the total internal surface of the tube, the inclusion of this interior perimeter recess does not affect the general properties of the tube.
  • the outer perimeter recess is at the lower edge and the inner perimeter recess is at the upper edge.
  • the outer surface of the tube is on which the filiform material is wound. This outer surface has a standardized length, defined by the width of the coil (plus the necessary margins).
  • a plurality of winding machinery takes the upper edge of the tube as a reference, so it is advantageous that the outer perimeter recess is not at the upper edge but is at the lower edge. In this case, the inner perimeter recess is at the upper edge that does not affect the winding process.
  • the inner perimeter recess has its rounded outer edge.
  • the perimeter recesses are preferably a step formed with two right angles, so that a small annular surface and a vertical wall are formed that form the perimeter recess between them.
  • this unwinding is done by the upper edge, whereby the filiform material can come into contact with the upper edge.
  • the inner perimeter recess has a flange at its end.
  • Another advantageous embodiment of the invention is when the outer perimeter recess is at the upper edge and the inner perimeter recess is at the lower edge. In certain cases this solution may also be of interest.
  • the outer perimeter recess has at least one of its rounded outer edges, and preferably both.
  • the outer perimeter recess and the inner perimeter recess each comprise a truncated cone surface, so that the truncated cone surface of the outer perimeter recess is suitable for resting on the truncated cone surface of the inner perimeter recess of a second identical tube tube . That is, the perimeter recesses are no longer simply formed with two right angles but include a truncated cone surface. This truncated cone surface allows, for example, a guided and self-centering of the tubes when stacked on each other.
  • a subject of the invention is also a coil of filiform material with a bobbin holder tube according to the invention, where preferably the material Filiform is polyester, polyamide or polypropylene. It is also advantageous to use bobbin tubes according to the invention for continuous spinning of polyester, polyamide or polypropylene.
  • Fig. 1 a set of stacked coils according to the state of the art.
  • Fig. 2 a first embodiment of a bobbin holder tube according to the invention.
  • FIG. 3 to 6 other embodiments of a bobbin holder tube according to the invention.
  • Fig. 7 a schematic detail view of two perimeter recesses with a truncated conical surface.
  • Fig. 8 a schematic view of the stacking process of two bobbin holder tubes according to the invention.
  • Fig. 9 a view of two coils with two bobbin holder tubes according to the invention, stacked. Detailed description of embodiments of the invention
  • Fig. 1 shows a partially exploded view of a set of stacked coils 1 according to the state of the art.
  • each coil 1 comprises a bobbin holder tube 3 on which, on each of its upper and lower edges, a support 5 is mounted. By supporting a coil 1 on the one immediately below, the respective supports 5 bump into each other. .
  • FIG. 2 A first embodiment of a bobbin holder tube 3 according to the invention is shown in Fig. 2. It is substantially a through circular cylinder with an upper edge 7, a lower edge 9, an outer surface 1 1 with a main outer diameter, an inner surface 13 with a main inner diameter and a hole 15 arranged in the vicinity of the lower edge 9.
  • This hole 15 defines the retention means of the initial section of the filiform material although, as already indicated above, these retention means may be defined with other geometries. In any case, these retention means are always close to one of the edges of the tube, which will be what is called the lower edge 9.
  • the bobbin holder tube 3 further comprises an inner perimeter recess 17 disposed on the upper edge 7 and a recess outer perimeter 19 arranged in the lower edge 9. Both recesses 17, 19 are formed by a step formed with two right angles, so that a section of cylinder wall of smaller thickness is defined. This section of wall is vertical, that is, it is parallel to the outer surface 1 1.
  • Fig. 3 shows a bobbin tube 3 similar to that of Fig. 2 but additionally rounded the outer edge 21 of the inner perimeter recess 17.
  • Fig. 4 a bobbin tube 3 similar to the previous ones, but with a flange 23 in its inner perimeter recess 17.
  • Figs. 5 and 6 shows a bobbin tube 3 "inverse" to the previous ones, in the sense that the outer perimeter recess 19 is at the upper edge 7 while the inner perimeter recess 17 is at the lower edge 9.
  • the bobbin tube 3 of Fig. 6 has, in addition, rounded the two outer edges 21 of its outer perimeter recess 19.
  • a schematic of the detail of two edges 7, 9 having a perimeter recess 17, 19 with a truncated conical surface 25 is shown in Fig. 7.
  • Fig. 8 shows a schematic view of the assembly sequence of a bobbin tube 3 as that of Fig. 2 on another, while in Fig. 9 the two bobbin tubes 3 of Fig. 8 with the respective coils 1 have been shown.
  • the assembly is made directly between the bobbin tubes 3, without using any type of support intercalated between both tubes.
