Description

The invention relates to a method of packaging in coils of a

  elongated material as well as the means for

  implementation of this method and the packaging made.

  In particular, but not exclusively, the invention applies to the packaging of coils of filiform product. Currently, in the packaging of different products (bare cable, insulated cable, special cables: steel wire, tube, etc ...) it is used wooden drums, plastic or metal and this requires for the unwinding, the the use of

motorized reel.

  In other cases, it is used removable drums on which the ligated products are conditioned and resumed on

removable reel.

  In other cases, the product is unwound by the center 15 with suitable devices.

  In this area, we also know many

coil variants.

  Generally, these coils each comprise two circular flanges permanently fixed to a hub intended to receive the elongate product winding while the flanges the

hold laterally.

  This type of conditioning gives good results but

  In particular, it criticizes it for being as cumbersome as it is empty and for allowing the subsequent unwinding of the outside of the winding.

  To remedy this drawback, it is known

(FR-A-2084705)

  winding the elongated product directly onto a winding mandrel which, during the winding, serves as a hub and then extracting the winding of this mandrel and pinching it between two independent flanges, preferably each provided with their center of a collar that is centered at the edge of the central passage of the winding and finally, - to ring the assembly formed by the flanges and the winding by means of links passed around the section

toric of this set.

  This packaging method therefore makes it possible to use assembly means which are not bulky when

  the elongated product has been debited.

  Unfortunately, the strapping is delicate and time-consuming and furthermore, this method of packaging is only suitable for an elongated strip product which is

unrolled from the outside.

  Indeed, the absence of hub prohibits the filiform product packaging which, before strapping, the turns could move and entangle and then, at the end of unrolling, whether from the inside or the outside the last layer of turns would collapse and the turns would become entangled. One result that the invention aims to achieve is a method of packaging elongated product coils that is suitable for both filiform products and those in the band, which allows a flow of both the interior and the outside and that does not require any

  other means of maintenance even at the end of unwinding.

  For this purpose, the subject of the invention is a process of the aforementioned type, characterized in that: - at least one false coil is produced, which is why, in a demountable manner, two flanges are assembled together by means of a series of so-called internal spacers, substantially uniformly distributed, at the periphery of the central cutout of each flange to form a false hub, - the false coil thus formed is engaged on a mandrel of diameter compatible with the inner diameter of the false hub, - place against the outer faces of the flanges of the means capable of wedging said flanges in radial position and to maintain them at the proper spacing, - the longiline product is wound around the false hub and therefore between the flanges and then when the winding is achieved the external edges of the flanges are connected to one another by means of a series of so-called external spacers, which perfect the locking of the winding carried out both by maintaining the flange spacing than by pressing on the product and finally,

  the wrapping mandrel is released from the packaging

thus constituted.

  For unwinding, at least one of their ends is disconnected, all the spacers of the series located on the side where the unwinding must take place while the others are left in place at their two ends for them continue to maintain the flanges and rolled up product

the end of the unwinding.

  The subject of the invention is also the means for implementing the method, which are characterized in that they comprise the means for constituting the coil coil and in particular: in diametrical dimensions in relation to those of the so-called false coil to be constituted, at least two generally circular flanges and substantially identical, each having a central and circular cut, - a series of so-called internal spacers which are rigid and of substantially identical lengths, which length is related to the desired spacing of the flanges, and, - to allow the dismountable assembly of the internal struts with the flanges, complementary- connection means provided at the ends of each of said inner struts, the others at the periphery of the blank

central of each of the flanges.

  These means of implementation further comprise a series of so-called external spacers which are rigid and of substantially identical lengths, which length is related to the desired spacing of the flanges, and to allow the dismountable assembly of these spacers. external 30 with the flanges, complementary connection means provided at one end of each of said outer spacers, the others near the outer edge of each of the flanges.

  The invention will be better understood with the aid of the following description given by way of non-limiting example, with regard to the

  attached drawing which shows schematically: - Figure 1: seen in perspective, a longiline product winding conditioned according to the method of the invention, - Figure 2: on a smaller scale, an axial section of the winding, - Figure 3 a view from above of the packaging shown in FIG. 1 but which, to present certain details, is partially and abnormally disassembled; FIG. 4: an axial sectional view of the packaging with two of the spacers represented in phantom and separated from the flanges,

  - Figure 5: a front view of the end of a spacer before assembly.

  Referring to the drawing, we see that the conditioning

  1 applies to windings of long products 2.

  It comprises a coil 3 composed of two flanges 5, 6

  connected by a hub 7 intended to receive the winding 4.

  A winding mandrel 8 is intended for

  support the spool 3 during the conditioning operation.

  Without being limited to the invention, the elongate product 2 shown in the drawings is filiform in nature. Instead of making the winding 4 around a single mandrel 8 and then report the flanges 5, 6, or use a coil 3 whose flanges 5, 6 are fixed permanently to a hub 7, according to the invention for conditioning the elongated product: - at least one false coil is made, which is why, in a demountable manner, two flanges 5, 6 are assembled together by means of a series of so-called internal spacers 10, substantially uniformly distributed at the periphery 14 of the central cutout 9 of each flange 5, 6 to form a false hub 7, - the false coil 3 thus formed is engaged on the mandrel 8 of diameter compatible with the inner diameter of the false hub 7, - it is placed against the external faces of the flanges 5, 6 means capable of wedging said flanges 5, 6 in the radial position and keeping them at the right spacing, - the elongate product is wrapped around the false hub 7 and therefore between the flanges 5, 6 then, when the winding is

realized, -

  the external edges 13 of the flanges 5, 6 are connected together by means of a series of so-called external spacers, which is perfect for locking the winding, both by keeping the flanges apart and by pressing the product and finally, - the mandrel 8 is released the packaging thus formed. For the unwinding, at least at one of their ends, all the spacers of the series located on the side where the unwinding is to take place are disconnected, while the others are left in place at both ends so that they continue. to maintain the flanges 5, 6 and the wound product

until the end of the unwinding.

  Preferably, in the case of unwinding from the outside, the two ends of the external spacers 11 are disconnected while in the case of unwinding from the inside, disconnects

  only the end of the inner struts 10 located on the side where the draw takes place and the spacers are assembled by their ends disconnected so as to produce a guide cone 20 of the turns of the unwound wire.

  For the implementation of this method, in addition to a mandrel 8 and means for holding the flanges, the invention uses the means including: - to form the false coil 3 and in particular: 25. in diametrical dimensions in relation to those of the coil 3 to form, at least two flanges 5, 6 generally circular and substantially identical, each having a central and circular cut 9, A series of so-called internal spacers 10 which are riaides and substantially identical lengths, which length is related to the desired spacing of the flanges 5, 6, - to allow the removable assembly of the inner struts 10 with the flanges 5, 6, complementary connection means 15, 16 provided at one end 12 of each spacers 10, others at the periphery of the cutout

  central 9 of each of the flanges 5, 6.

These means of implementation further comprise a series of so-called external spacers which are rigid and of substantially identical lengths, which length is related to the desired spacing of the flanges 5, 6 and, to allow the removable assembly of these external struts 11, with the flanges 5, 6, complementary connection means 15, 16 provided at the ends of each of said outer struts 11, the others near the edge

  outside 13 of each of the flanges 5, 6.

  The internal and external struts 10 may be identical but, in a preferred embodiment of the invention: the internal struts 10 have a cross section giving them a concave cylindrical bearing so that it matches the convexity of the mandrel 8 and this, without creating extra thickness, the outer struts 11 have on their body 111 at least one reinforcement means to the stresses of

  bending received from the outside and / or the product on which they support.

  These reinforcing means 17 consist for example of at least one longitudinal rib embossed in the spacer.

  In a form also preferred for implementation, the complementary connection means 15, 16 comprise: on the one hand, both near the outer edge 13 of each flange 5, 6 and on the periphery 14 of its central cutout 9, at least one anchoring rib 19 projecting on the outer face 20 of the flange 5, 6 and, on the other hand, at each of the ends 12 of each spacer 10, 11: to a stop 21 facing the inner face of the flange 5, 6 connecting to the same end and located relative to the stop of the other end at a distance substantially equal to the spacing between the flanges 5, 6 so as to cooperate with the inner face 18 of the flange 5, 6, at least one lug 22 extending each spacer, 11 over a length at least sufficient to come around the profile of the anchor rib 19 and engage behind it by folding when each spacer 10 He is in contact, through his stops 21, 5, 6. In an advantageous form of the invention, the connection means 15, 16 comprise locking elements 23, 24 which consist: on the one hand, on each flange 5, 6, in a plurality 10 cuts 23 made to the right of the anchor ribs 19 and - on the other hand, on the ends 12 of the struts 10, 11, in at least one tab 24 extending each end over a length at least sufficient to be able, at the mounting the spacers on the flanges, be folded about at right angles to come substantially in the plane of the inner face 18 of the flange 5, 6 to the right of which it is located, then folded again to be engaged in one of the cutouts 23 and finally folded towards the end of the crossbar, preferably up to

  apply on the outer face 20 of the flange 5, 6 so as to lock the connection.

  As provided by the invention, each of the ends 12 of a spacer 10, 11 is extended by three tabs 22, 24 parallel, a central lug 24, generally centered on the longitudinal axis of the spacer, constitutes the element locking of the connecting means 15 of each end of a spacer on one of the flanges 5, 6, and two other tabs 22 arranged on either side of the previous one and which constitute said connection means 15 of each end of a

  spacer on one of the flanges 5, 6.

  The means for firmly holding the flanges 5, 6 during the winding of the product consist of false flanges

  51, 61 reported on the winding mandrel 8.

  Those skilled in the art are able to determine the number

  optimal spacers 10, 11 which must be equipped with the 35 conditioning device to achieve excellent support.

  As an indication, for a flange diameter of one thousand two hundred millimeters and a central cutting diameter of six hundred millimeters, good results have been obtained by equipping the outer edge of the flange with six spacers distributed every

15 20 25

  sixty degrees and equipping the periphery of the cut

  center of four spacers, in turn distributed every ninety degrees.

  In order to connect the beginning of a new reel, before the

  At the end of a preceding coil, at least one of the ends of the winding of at least one of the flanges may comprise a recess 25 clearing the passage for the corresponding end.

  The method of the invention has the advantage of using metal flanges and a spacer system, to quickly assemble flanges that can "position"

  on a retractable mandrel provided with two false holding flanges.

  The product being wound, it is sufficient to position the spacers on the outside and both lock the two flanges that maintain the product by serving as protection.

  The product being conditioned, it remains only to dismantle the retractable mandrel to extract it and place it on a rocker on which the product has been placed in a position i allowing to unroll from the inside to the vertical or possibly horizontal if desired and always in a static position.

  An impression being provided on the flanges for this kind of unwinding, if one wants to do it continuously, simply resume the departure of another package or crown and connect to the outer end of the winding crown and this without stopping.

  The reeling finished, we can recover the flanges and possibly the spacers that can be easily put on pallet and this represents a small volume.
