Definitions
- the present invention is concerned with separating elements to be placed between adjacent tiers of yarn spools stacked onto a pallet, such elements being also known as trays or layer separators.
- the spools are disposed onto a pallet by automatic machines and then the assembly is wrapped with 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 in form of trays are inserted between the spools of two adjacent tiers, with such trays also performing a lateral restraining function and making easier the centering of the spools by the packaging machine and their subsequent picking up.
- This solution has the drawback of requiring a manual positioning of the cones into the centering and blocking holes, and moreover such cardboard trays are not reusable since they are subjected to breaking and damages.
- Separating trays have also been manufactured of plastic materials and forming the spool centering cones integral with the tray body. Although these trays are stronger and longer lasting, as well as adapted to be reused, nevertheless they exhibit several drawbacks.
- the cost of the mold is high due to the large dimensions of the article to be molded. Moreover, when trays with different configurations are requested, e.g. because of different diameters of the spools to be stacked or different spacings provided between the cones, several molds are to be manufactured, each with a corresponding high cost.
- a further drawback of the known plastic material trays comes from the fact 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 step when a machine picks up single trays from a stack and place them between the tiers of the yarn spools.
- An unstable balance of the spools can be of prejudice for automated procedures, requiring manual interventions and as a general rule by increasing the cost for positioning and packaging the spools on the pallets.
- Examples of trays formed of cardboard 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 for yarn spools packaging with an associated connecting system in the packaging of yarn spools.
- This object of the present invention ia accomplished through a separating tray for yarn spools having the characteristics recited in claim 1.
- the modular tray according to the invention has a low manufacturing cost since the size of the mold is small and each of the modular members requires a small amount of plastic material. Namely, on one hand the damaging of a tray portion can be overcome by replacing only the corresponding modular tray member, and on the other hand breakages are less frequent due to the stiffening caused by the modular construction and since the trays can be carried or handled as components of reduced dimensions. Moreover the tray according to the invention is ecologically convenient since it reduces the amount of plastic wastes.
- the trays formed by means of the modular members in accordance with the invention exactly fit over each other thus allowing for an optimum stacking thereof.
- a separating tray or separator 1 for tiers of yarn spools is formed of a plastic material and provides a substantially flat or planar base surface from which extend projections 2 for engaging the yarn spools.
- the base surface of the tray 1 is provided with lightening openings and more precisely, as shown in Fig. 2, with a plurality of openings 3 formed as sectors of a circle concentrically disposed about each engagement portion 2, so as to define spokes 4. Additional openings 5 are moreover provided in the surface of base near the corners thereof.
- the separating tray 1 is formed by a plurality of smaller tray members 10 assembled together, equal to each other in the illustrated embodiment, and laterally provided with means 6 adapted to allow a (non permanent) coupling or connection between adjacent tray members 10 as will be illustrated with more details in the following.
- Each of the tray members 10, illustrated with more details in Figs. 2, 3 and 4 comprises a substantially flat base 11 provided with an orthogonal rim or flange 18 extending along the entire periphery of the member 10, on both faces, and protruding means 2 for engaging the yarn spools.
- a standing or protruding cylindrical portion 12 adapted to fit the inner space of the core (see Fig. 4) of a yarn spool, and three portions 13, located inside the cylindrical portion and projecting therefrom, adapted to make easier the spool insertion.
- such elements are realized as projections with an angular extension smaller than 45° and offset by 120° in respect of each other.
- the tray member 10 there are formed three further portions 14 protruding therefrom (only two visible in Fig. 4), with a construction similar to that of the projections 13, and adapted to facilitate the insertion of a spool. Also the projections 14 are offset by 120° from each other and they are further offset with respect to the projections 13 so that when the members 10 are stacked one over the other, the projections 14 occupy the spaces between pairs of adjacent projections 13 of the underlying member, thus reducing the overall size of a stack of members 10.
- tray members 10 have a rectangural or square shape, however it falls within the scope of the invention to realize tray members having any desired polygonal shape, either regular or unregular, as well as to form the tray 1 by coupling together tray members 10 having shapes different from each other.
- each of said tray members 10 there are provided pairs of elements 6 formed as recesses for joining together two adjacent elements by means of elastic clips 19.
- such clips are formed as elastic components of a plastic material having a W shaped cross-sections, adapted to engage and fasten together two tray members located side by side.
- the engaging means can be used for accomplishing the function of the illustrated engaging means and clips.
- the corners of the base 11 are preferably beveled so as to form a 45° chamfer for facilitating the assembly. Near the chamfers there are formed openings 5 having a generally trapezoidal shape with an arcuated longer base.
- An annular groove 9 is formed around the cylinder 12, this groove being provided only on that face of the tray member on which the yarn spool 20 rests, and being useful to protect the end or "tail" of the yarn wound on the spool.
- the trays located at the top and the bottom of the pallet require projections on one face only, with the other face being preferably smooth for a good wrapping of the plastic material or of the packaging cardboard box.
- the projections 14 extending downwards are to be eliminated for the top tray member, and the projections 13 and the cylinder 12 are to be eliminated in the bottom tray member. This can be accomplished either by cutting the unnecessary parts, or by locating suitable inserts in the mold and molding dedicated top and bottom trays, respectively.
- the members 10 forming a tray comprise engagement means for a single spool on each face, and the illustrated tray is for a tier of six spools.
- engagement elements for two or more spools can be formed on each face of a tray member.
- the tray members can have different sizes and typologies, for example incorporating means adapted to engage two spools on each face and means adapted to engage a single spool for each face such as those illustrated in the Figures.
- FIG. 5 illustrates two additional alternate embodiments of the invention indicated by 10' and 10''.
- the tray member 10' is not provides with openings 3 and 5 and the four corners are at 90°, whereas according to another embodiment of the invention the tray member 10'' does not provide openings 3 and 5, and has three 90° corners and one 45° beveled corner.
- the above disclosed tray member 10' and 10'' not provided with openings 3 and 5 can advantageously be used in assembling separating trays to be positioned at the bottom and the top of the pallet, thus preventing the dust from entering the package.
- tray members 10'' - of the type having a single chamfer - will be disposed at the four external corners of the whole separating tray whereas two tray members 10' - of the type having four 90° corners - will be used for the remaining (inner) members.
