Definitions

  • the present invention refers to separating elements for yarn spools stacked on a pallet, also known as trays or layer separators.
  • the yarn spools are positioned on a pallet by means of automatic machines and then wrapped by a film of heat-shrinkable plastic material or packaged in cardboard boxes. Other automatic machinery is later used to pick up the yarn spools from the pallets.
  • separators are inserted between the layers, such separators also performing a lateral retraining function and making easier the centering of the spools by the packaging machine and their subsequent picking up.
  • the cost of the mold is high due to the large dimensions of the article to be molded. Moreover, being the spools supported only in their central part, in correspondence of the support on which they are wound, the stability of the system pallet-separating tray-spools is highly reduced, especially if the number of stacked layers is high. This implies the need of paying particular attention during the shifting and transporting of the pallets. An unstable equilibrium can in fact jeopardise the automated operations, requiring manual operations and, in general, increasing the manufacturing costs.
  • a further drawback common to both the cardboard trays with plastic cones and the plastic ones, consists in that the upstanding cones all protrude at the same locations on each tray thus preventing an effective superimposing of the stacked trays, typically during the encasing phase when a machine picks up single trays from a stack and place them between the tiers of yarn spools.
  • Examples of cardboard trays are illustrated in US-A-4 141 447 (with cut-outs folded upright for supporting the spools), and in EP-A-465 815.
  • Plastic material trays are disclosed for example in EP-A-229 392, EP-A-194 405, US-A-4 142 634, US-A-4 042 108, EP-A-514 985.
  • GB-A-1 544 983 discloses modular component parts with an associated connecting system for forming centering devices in the packaging of yarn spools.
  • This object of the present invention is accomplished through a separating element for yarn spools having the characteristics recited in claim 1.
  • the separating element realised according to the invention is substantially flat, allows to support the spool on a smooth surface distributing uniformly the weight and it is realised in modular form.
  • a modular element of a separating element for layers of yarn spools is realised in plastic material and provides a base structure 2 having in its central portion means 12 for the engagement with the yarn spools.
  • the base structure 2 is realised in a single piece of plastic material and consists substantially of a perimetrical edge 6, that runs along the whole periphery of the structure 2, and a plurality of orthogonal rigid elements 8 disposed radially from a central ring 12 toward the perimetrical edge 6, defining a plurality of areas.
  • a second ring 20 defines externally empty areas 10 separating them from filled areas 4 comprised between the external ring 20 and the perimetrical edge 6.
  • the central circular ring 12 acts as engaging means with the yarn spool.
  • the support on which the spool is wound that normally partially projects from the spool, penetrates into the ring 12.
  • the support, and accordingly the whole spool, is therefore laterally constrained.
  • the engaging means could be realised as a central projecting element, that penetrates into the support of the yarn spool, limiting the lateral movements of the spool itself.
  • the supporting element 30 is a thin disk made of plastic material, smooth and perforated in the middle. Moreover it is provided with lockpins 14a, 16a suitable to be inserted in corresponding holes 14 and 16 present in the base structure 2 respectively in correspondence of the internal ring 12 and of the external ring 20.
  • lockpins 14a are inserted into a perimetrical portion 15 external to the internal ring 12 while the lockpins 16a are inserted in holes 16 provided in the filled areas 4 near the external ring 20.
  • the perimetrical orthogonal edge 6 comprises, on each side, means 18 for allowing the junction between adjacent modular elements by means of elastic clips.
  • Figure 2 shows in section, according to line A-A, the element of figure 1.
  • the rigid elements 8 that provide a concave supporting surface for the supporting element 30.
  • This expedient allows the supporting element to bend itself partially under the weight of the yarn spool and to adapt itself to possible protrusions or irregularities present in the base surface of the same yarn, increasing the contact surface between yarn spool and supporting element reducing the load for unity of surface.
  • the support provided by the internal ring 12 is lower then the supporting plane of the external ring, allowing the supporting element 30 to adapt itself to the natural form slightly conical of the base of the yarn spool.
  • the base structure 2 is perfectly symmetrical and could provide support also for a second supporting element situated on its lower side.
  • the lockpins 14a, 16a allows in fact to insert and remove the supporting elements from the base structure 2 in order to change the configuration of the separating element or for possible substitutions due to partial breakages.
  • the same separating element can therefore be used as a separator between layers of spools, using two supporting elements, or as a base element laying on the pallet or as an upper element on the top of the stack of spools, using only one supporting element.
  • Figures 6 and 7 show in detail, respectively in a plan view and in a sectional view, the circular supporting element 30 of the separating element. In particular are visible the lockpins 14a, 16a suitable for inserting in corresponding holes 14 and 16 provided in the base structure.
  • FIG 3 shows a separating element, comprising four modular elements joined together by means of elastic clips 32, wherein each module is provided with an upper supporting element 30 for the yarn spools, visible in Figure, and eventually with a second supporting element applied below on the opposite side.
  • the modular separating elements are, advantageously, rectangular or square shaped, nevertheless it is provided that said elements could have any polygonal shape regular or irregular and that the separating element could be obtained by joining separating elements having different shapes.
  • the number of elements that they compose the separating element depends, however, by the dimensions of the single yarn spools and by the dimensions of the supporting pallet.
  • Figure 4 shows a different embodiment of a modular separating element, structurally similar to the modular element of Figure 1.
  • the supporting structure for the flat supporting element for the body of the spool and the supporting element itself are in fact identical to those of the separating element described above.
  • the filled areas 4 presents on the contrary some differences. In particular they present, on a first side, four protruding areas 40 and four recessed areas 42 that correspond, on the opposite side, respectively to four recessed areas and to four protruding areas.
  • protruding areas 40 of a modular element could be inserted into corresponding recessed areas of a superimposed modular element. In this way it is favoured the joint stacking for the stocking and transporting of the modular elements or the assembled separating elements without the spools.
  • the overlap of the separating elements is also favoured by the fact that they are practically flat and without protruding supports for the spools.
