Description

PACKAGING FOR WIRE REELS
The present invention relates to a packaging for spools of thread and, more specifically, a packaging intended for the handling and storage of windings of textile yarn, in particular glass yarn, said windings being on hollow supports also called "cops" .

 Various packages for wire spools already exist and ensure, to a greater or lesser extent, the protection of the spools during their transport. In the field of textile yarns where the windings are presented on supports or cops directly usable on the trades or textile processing equipment, it is essential that the spools are maintained effectively within the packaging, without risk of deformation or damage to the supports, just as it is essential to protect the windings from any impact or damage.

 It is also desirable, in the field of textile yarns, to be able to have small quantities of windings, easily extractable from the packaging and transportable by an operator, for use in certain applications but also for practical purposes, for a more convenient unloading of coils.

 It is already known, as explained in US Pat. No. 3,094,211, to use a cardboard packaging in the form of a container with lateral opening in which a series of trays provided with protuberances are stacked on which the coils fit. . This packaging does not however ensure total stabilization of the coils, said coils being held only by one of their ends on plates themselves simply superimposed.

Furthermore, such a system is not easy to handle and has a relatively large size.

 It is also known to secure coils together in a package by fitting them by their ends, as indicated in patent EP 229 392.

 In this patent, the packaging presented comprises a pallet bottom, a set of layers of trays produced by molding, a cover and connecting means for holding the set; each tray also has a series of cells in which the base of the coils is positioned and in the center of which an opening is made allowing the head of the lower level coils to pass, said head coming to fit into the recess of the base of the coils located on said plate.

 Such a system is stable and easy to handle as a whole and includes several independent coils transport units, namely the trays. However, on the separate trays, the coils, separated from each other, are only weakly held by their base within the cells and the transport of a tray by an operator is impractical. Furthermore, this type of packaging only applies to coils whose outside diameter of the head is less than the inside diameter of the base recess.

 A first object of the invention is to provide a practical packaging for the transport and storage of any type of spool of textile yarn, and in particular a packaging making it possible to transport and store a large number of spools firmly held in a determined position, said packaging being able to dissociate into a series of elements, each separate element containing a reduced number of coils in a stable position and being capable of being easily transported by an operator to the place of use of said coils.

 The present invention also relates to a packaging that is simple to produce, can be stacked and all the components of which are reusable and / or recyclable.

 These goals are achieved by packaging for spools of textile yarn in which said spools are superimposed in at least two layers resting on at least one base provided with feet, the spools of each layer being distributed in at least two juxtaposed trays, each tray having walls provided with gripping means as well as a bottom lined with at least one plate, this lined bottom comprising on its upper face a series of regularly spaced bosses on which are inserted the hollowed-out bases of the coils and on its face lower protuberances delimiting regularly spaced zones in which can be inserted the head of the coils belonging to the lower tank, said packaging being crowned with at least one cover and the whole key (s) -bacs-cover (s ) being made integral by one or more connecting means.

 The packaging thus defined has many advantages which we will explain in particular during the following description.

 The packaging according to the invention is firstly transportable by any means usually used for transporting packaging. In particular, the base or bases provided with feet allow the transport of said packaging by forklift, the fork of the carriage in question then being positioned between the feet of the base or bases. Note also that it is possible to provide additional gripping means, such as cords, surrounding the packaging and provided, for example, with a loop or a ring to allow the seizure of the assembly by d other systems such as lifting systems.

 According to a preferred embodiment of the invention, the base or bases on which the layers of coils rest are provided with flanges allowing the positioning and the setting of the trays supporting the first layer of coils. Other positioning means can be used and, in particular, the upper part of the base (s) can be provided with studs which can fit into the protuberances located on the underside of the containers coming into contact with it.

 Note that, in the case where the packaging comprises several bases, the bases in question are preferably provided with flanges having projections, recesses ... making it possible to associate the bases with one another by fitting them together. The presence of several bases already constitutes within the packaging a possibility of dissociation of said packaging into separate elements allowing the handling of reduced quantities of coils, the smallest dividing elements of the packaging being constituted by the trays.

 Indeed, each tray according to the invention contains a limited number of spools of wire and is easily removable to allow the unloading and the transport by an operator of small quantities of spools. These trays are easy to handle thanks to the gripping means provided on their walls, which walls are of sufficient height to prevent any possible tilting out of the tray from a badly positioned reel and offer the wire windings additional protection against any impact or soiling. In most cases, the height of the container walls need not be almost equal to that of the coils they contain. It is sufficient that their height is for example between 1/3 and 2/3 of that of said coils. The gripping means preferably consist of two handles each disposed on one of the shorter walls of the tank, these handles can be molded in said walls or coincide with any edges of the tank.

 It should be noted that the presence within the packaging of the containers making it possible to transport small quantities of reels constitutes one of the main advantages of the packaging according to the present invention. Another important advantage lies in the system of bosses and protuberances arranged in each tank. Thanks to this system, each coil is positioned and immobilized at any level and at any time. The diameter of the bosses is adapted to the internal diameter of the hollow supports or "cops" carrying the winding so that the coils fit precisely on the bosses and are thus kept fixed after positioning. Similarly, the height of the bosses is provided to allow the coils to be held in each tank when it is detached from the assembly. Thus bosses with a height of several centimeters keep the coils in place even when the container is accidentally tilted during handling.

 The protrusions are, in turn, chosen so as to delimit a space of diameter adapted to the diameter of the coil heads so that the protrusions come to fit on the coil heads just as the bases of the coils fit on the bosses. The protrusions may consist of rings or cylinders, portions of rings or cylinders, in impressions of the coil heads ... The height of these protrusions is less than that of the free end of the supports, that is ie the end not having a winding, to avoid contact of the protrusions with the winding and thus the risk of damage to the winding in question.

 The fixing of the coils is therefore done at two levels, by two different and independent fixing modes each adapted to each of the ends of the coils and not requiring any particular adaptation at the level of the coils. The packaging can thus be applied to any type of spool of textile thread, suitable for fitting or not, with or without a shoulder ...

 Note that the bottom and the plate which doubles it are assembled in such a way that the bosses are plumb with the protuberances located under the tank. According to an embodiment of the present invention, a plate carrying the protrusions on one of its faces is glued on its other face under the bottom provided with bosses. Conversely, according to another embodiment of the present invention, a plate having the bosses on one face is glued on its other face to the inside of the bottom, the lower face of which is provided with protuberances.

 As mentioned above, on the last layer of coils is placed at least one cover. Preferably, a single cover is used crowning the coils of the upper layer of the packaging and provided on its upper face with reinforcing bars to be able to support other packaging. The cover advantageously has edges and is preferably provided on its lower face with recesses, or protuberances in the manner of the underside of the tank, in which the upper ends of the coils of the upper layer will be positioned.

The cover serves inter alia to protect the reels of the last layer while fixing their free end and can serve as a seat for a similar package so as to allow stacking of several packages.

 The packaging comprising the various elements mentioned above is stable at all levels and thus remains assembled, due in particular to the joining of the layers together by means of bosses and protuberances but also thanks to the use of connecting means such as cords, belts, plastic or metal bands ... It is also possible to provide protective films for the packaging, for example heat-shrinkable films, just as it is possible to provide sachets or individual protective films, for example of plastic, to protect the coils against soiling.

 Note that, preferably, for the sake of environmental protection and economy, all the constituent elements of the packaging are reusable and / or recyclable. In particular, the bases, the trays and the covers are preferably produced by thermoforming of a plastic material and are easily reusable. The protective films and individual protective bags made of plastic, which cannot be reused, are advantageously recyclable.

 It is also interesting to note that the packaging, once empty, has a reduced volume, the containers being able to stack one inside the other. For this purpose in particular, the containers according to the invention are preferably provided with slightly inclined walls so that their opening is of dimension greater than that of the bottom and allows stacking; the various stacked elements can thus be more conveniently returned to the supplier.

The following examples will make it possible to better understand the invention without limiting its scope and will reveal other advantages and characteristics of the invention. These examples are presented with reference to the accompanying drawings in which
FIG. 1 represents a perspective view of a preferred packaging according to the invention,
FIG. 2 represents an exploded view of the packaging according to FIG. 1, except coils, connecting elements and film or protection,
- Figure 3 shows in cross section a portion of the package according to Figure 1, highlighting the coil stabilization system within the package.

 In the preferred embodiment of the present invention illustrated in Figures 1 and 2, the package 1 comprises two bases 2 each provided with two rows of feet 3 allowing the transport of said package by forklift.

These bases are provided with flanges 4 having projections 5 and complementary recesses 6 by means of which said bases fit into one another. The edges of the bases also make it possible to position the first row of containers coming into contact with said bases.

Indeed, on each base there are two layers of coils 7, these coils being distributed by layer and for each base in three trays 8 juxtaposed. Each container has inclined walls 9 to facilitate the subsequent stacking of said empty containers one inside the other1 said walls being provided with slight recesses 10 on the shorter sides of the containers. The recesses in question each house a handle It allowing the transport of the containers by an operator.

 Each tank also has bosses 12 not shown regularly spaced at its bottom and is lined with a plate 13 carrying the protrusions 14 according to the invention. This plate provided with flanges is glued under the tank so that the bosses are plumb with the protrusions.

 In this embodiment of the present invention, each tank contains eleven coils positioned on the bosses distributed in three series staggered inside said tank and the protuberances are in the form of portions of rings arranged at 1200 from one another.

 The packaging also includes a single cover 15 provided with a reinforcing bar 16 and notches 17 through which plastic links 18 are passed, enabling the assembled packaging to be kept. The cover is also provided with not shown recesses in which the heads of the coils of the upper layer of the packaging are housed. This cover in one part allows the stacking of a second package on the package considered so as to have a total load of 264 coils.

 In order to protect the coils against soiling, each coil is wrapped in an individual protective bag made of plastic material, not shown, and the packaging is covered with a protective film 19.

 As shown more precisely in FIG. 2, the packaging thus formed can be separated into layers of six bins or into stacks of layers of three bins if the two bases are separated, or more simply into bins.

Each bin allows eleven reels to be transported as indicated above, each reel weighing approximately 3 kg for a height of 50 cm. The height of the walls of the tanks is in this case about 20 cm.

 FIG. 3 illustrates more precisely the fixing systems formed by the bosses and the protuberances located in each tank previously defined. Each coil 7 fits via its hollow support on bosses 12 having in the case considered a height of the order of 7 cm. The dimensions of these bosses are calculated so as to allow the tanks to be tilted to 45 "without risk of destabilizing a coil.

 Furthermore, the coil heads 20 of a layer lower than that considered are housed in the protrusions 14 located under the tank of the layer considered and having a height of the order of 2 cm. The height of the free ends 21 of coils being of the order of 5 cm, there is therefore no risk of contact of the protuberances with the windings of wires 22.

 The packaging according to the invention is intended for all types of spools of textile yarn and in particular spools of textile glass yarn.
