Description

COIL POSITIONING DEVICE AND

  PACKAGING METHOD USING THE DEVICE

  The present invention relates to a device for enabling easy and safe positioning of coils of continuous flexible material for their transport and storage, as well as a method of packaging such coils using this device. Continuous flexible materials such as films Papers, cartons, fabrics or the like are generally wrapped around a mandrel to be handled, transported and fed during their use or processing. Thus, coils of flexible or continuous material, which will be called hereinafter reel of film, are formed for the sake of clarity and simplification. To avoid damaging the flexible material or the film during the handling or storage of the coils, flanges are generally mounted on each end of the mandrel. These flanges have a dimension greater than the thickness of the coil so as to form a bearing face when the coil is deposited on the ground or a bearing base such as

than a palette.

  Thus, for transport or storage of the coils, they can be arranged in packaging cartons, the setting of the coil being made by filling the cardboard with inserts, for example cardboard plates. This system has many disadvantages, in particular a material consumption (cardboard) important for

  make the packaging, material that is thrown or destroyed after using the reel.

  To avoid this consumption of cardboard and simplify the packaging, it has been proposed to arrange the coils provided with flanges directly on support bases such as pallets, and to wedge the flanges by fixing wedges on the supporting base of the part and else of each flask. These wedges are usually wooden cleats nailed to the pallets. This method has a major disadvantage residing in the fixing of shims during packaging and their removal for the use of the reels. In addition, this method makes it possible to wedge only the lower edges of the flanges, which may prove to be insufficient during a

  storage or transport by stacking of several reel heights.

  Finally, it has also been proposed, for coils of small.dimension, plastic flanges of sufficient strength for stacking the coils; However, these flanges can not be suitable for coils of medium or large width, and high weight. In addition, these flanges can not be used for spool coils. One of the aims of the present invention is to provide a suitable device for all types of coils, especially for coils of medium and large width and high weight for positioning and wedging flanges without requiring significant manipulation. This device is recoverable and can be returned to the coil manufacturer for reuse. This device therefore reduces the amount of packaging rejection. he can

  be used with any type of reel namely spool chuck overflowing or leveling.

  For this purpose, the invention proposes a device for positioning a reel of flexible and continuous material such as a film of synthetic or natural material, fabric, paper or cardboard, enabling correct packaging and positioning to be achieved. and

  for transport or storage.

  This device comprises at least one means for receiving and holding each flange mounted on each end of the mandrel of the spool, and at least one means for securing the means for receiving and holding a flange with the means of

  receiving and holding the other flange.

  This device can be used with the coils, said to flaring mandrel, ie to

  mandrel of length equal to the width of the flexible and continuous material wound thereon.

  On the ends of this mandrel are removably mounted flanges of polygonal shape, for example of square shape, and having a central orifice of diameter close to that of the mandrel. The fastening of the flanges can be carried out by any conventional and known means, such as spacer with collar coming to fit into the mandrel, spacer coming from material with the flange and forming a means of interlocking thereof

in the chuck.

  It can also be used with a second category of so-called over-mandrel coils, that is to say coils whose length of the mandrel is greater than the width of the flexible material wound thereon. The flanges used for this type of coil may be identical to those used with first class winding chucks. However, it is preferable to use flanges having an oblong opening opening on one side of the flange and allowing the passage of the end

  protruding from the mandrel which comes to rest on the bottom of the opening.

  According to one characteristic of the invention, the receiving and holding means is formed by a bar having a flat bearing surface on which the side of a flange will rest, and at least one vertical wall coming into contact with the face. flange not adjacent to the coil to thereby maintain it and prevent it from deviating from the

  coil under the effect of weight or vibrations and movements generated during transport.

  In one embodiment of the invention, this bar has an L-shaped section. This bar forming the receiving and holding means may have a U-shaped profile, defining a housing in which is disposed a side of the flange. The branches of the U

  may be of equal or unequal height.

  Of course, it is possible in a device according to the invention to use to maintain one of the flanges, a receiving means and holding constituted by a U-shaped bar and the other flange, a receiving means and The use of at least one L-shaped bar makes it possible to facilitate the adjustment of the spacing between the two receiving and holding means, in particular when the flanges are brought into their housings formed by said means, in the embodiment of the invention comprising means for securing the receiving means

  constituted by a bar with adjustable width.

  According to another characteristic of the invention, to limit the sliding of the device of the invention on the floor or support base on which it is arranged, the flat face of the bar opposite to the bearing face, comprises a non-slip means constituted for example by asperities formed on said face or attached thereto, for example by gluing or fixing a non-slip material, or more simply by protuberances formed

  on this face, for example by stamping the bar, grooving or ribbing.

  According to the invention, the device comprises a means for securing the means for receiving and holding the flanges. This securing means is formed in one embodiment of the invention of at least one rod on the ends of which are fixed of

  temporarily or not the bars forming the receiving means and maintenance.

  In a preferred embodiment of the invention, this rod is adjustable in length so as to adapt the spacing between the bars forming the receiving means and

  maintaining the width of the coil that is to say the spacing between the flanges.

  Advantageously, this rod is a telescopic rod or consists of several

  elements that can slide relative to each other.

  These rods may include graduations to determine and adjust

easily their length.

  Means for maintaining the desired length of the telescopic rod or more generally the stem of variable length, are numerous and well known. By way of example, there can be mentioned pins, screw / nut systems introduced into orifices provided on each element of the rod, or a clamping screw provided on an element and coming to take

support on the other element.

  Thus, any device for adjusting and blocking the length of the fastening rod may be used without departing from the scope of the invention. We can cite,

  for example locking systems by keys, pins, ratcheting or the like.

  It is also possible to provide a pneumatic telescopic rod, or to

rack and pinion for example.

  According to one embodiment of the invention, when the length of the bars forming the receiving and holding means is small, a single rod makes it possible to secure two receiving and holding means. However, when this length is relatively high, for example greater than 50 cm, it is preferable to have at least two securing rods each of which is preferably secured to the neighborhoods of the ends of the bars.

  receiving and holding so as to form a rigid frame.

  Indeed, the length of the reception and holding bars can be variable. Thus, it can be relatively small to only come into contact with a short reach on one side of the flange. In this embodiment, particularly interesting for coils of small size and weight, the device of the invention can be placed in the middle

on the support side of the flange.

  It is also possible to have a device according to the invention at each

  end of the support side of the flange.

  However, in the preferred embodiment of the invention, the bars forming the means for receiving and holding the coils or flanges have a length close to the length of the side of the flange. By neighbor it should be understood that the length of the bar may be between about 50% of the length of the side and about 120% thereof. In this embodiment, the bars are advantageously secured between

  they by at least two securing rods.

  It may also be advantageous to provide means for fixing the device of

  the invention on a support base, for example pallets.

  It is also possible, in another embodiment of the invention, that the device of the invention comprises elements fixed or coming from material with either the bars forming the receiving and holding means or the securing rods forming a base support. These elements form a gripping means of the device / reel assembly for conventional gripping devices such as forks forklifts. The device of the invention can be made of any rigid material. Preferably, the device is made of metal such as steel advantageously protected against the risk of corrosion. The invention also relates to a method for packaging a coil of flexible and continuous material such as a film of synthetic material, comprising polygonal flanges disposed on the ends of the mandrel. This method consists in arranging the lower or bearing sides of the flanges in respectively the means for receiving and holding a device according to the invention. This device is advantageously arranged

  on a support, a base such as a pallet.

  The three elements coil, device and base of the support are then advantageously secured to each other by any suitable means such that, for example,

  for example, by straps, belts, bands or the like.

  According to a preferred embodiment of the invention, the method also consists in arranging at least one device according to the invention on the upper edges of the flanges so as to stiffen the assembly. In this configuration, the coils can be stacked

  on several heights, especially for storage by stacking.

  Furthermore, the positioning rods and holding the device or devices disposed on the upper edges of the flanges can advantageously serve as a bearing surface for the fastening means of the coil assembly, pallet, thus avoiding a support thereof on the film. These securing means are, for example, straps or metal strips or not arranged around the coil / pallet assembly according to the method of

  strapping commonly used in the field of packaging.

  Moreover, in certain cases, in particular for the flanging chuck coils, it is possible to mount a bar for holding the interlocking of the flanges in the mandrel, this bar being fixed in a removable manner, for example by interlocking at its ends, on the bars forming the means for receiving and holding the devices of the invention. The advantages of the device and method of the invention are easily understood. One of its advantages lies in the fact that the positioning devices of the coil are easily recoverable during the use thereof and

  Reusable for packaging and storage of a new reel.

  In addition, the device of the invention has a small footprint and can be returned to the reel sender to be reused again. This feature is of great interest in view of the development of new and increasingly stringent legislation on the disposal of waste and the limitation of the use of packaging.

non-recoverable.

  The device of the invention also has the advantage of being usable for all

types of coils.

  Other objects, advantages and features of the invention will become more clearly apparent

  in view of the detailed description below made with reference to the accompanying drawings in

  which: - Figure I is a schematic perspective view of an embodiment of a device according to the invention, - Figure 2 is a schematic perspective view of a set of two flanges maintained by devices of the invention shown in Figure I arranged on a pallet, and - Figure 3 shows a coil with flush mandrel packaged by means of

devices of the invention.

  Referring to FIG. 1, a device I for positioning and holding according to one embodiment of the invention comprises two U-shaped bars 3, 4 having a bearing face 5, 6 and two vertical walls 7 , 8, 9, 10. The bars 3, 4 are interconnected, in the illustrated embodiment, by two rods 13, 14 telescopic comprising a hollow element 13a, 14a connected to a bar 4 in which can slide another element 13b, 14b. This second element 13b, 14b is connected to the other bar 3. The means for fixing the elements forming the rods 13, 14 on the bars

  3, 4 may be arbitrary and are, for example, weld lines.

  In the illustrated embodiment, the section of the rods 3, 4 is square.

  However, this section can have any shape such as round,

rectangular, for example.

  The elements 13a, 13b and 14a, 14b are locked in movement by a locking means such as a screw 15 disposed on the elements 13a, 14a whose end comes into

  contact in the bottom of a groove 16 formed on one side of the elements 13b, 14b.

  Thus, it is possible to adjust the spacing between the two bars 3, 4 according to the

  width of the coil, or more exactly the distance between the two flanges 11, 12.

  The device of the invention comprises on the outer surface U of the bearing face 5, 6 of the bars 3, 4, protuberances formed in the illustrated embodiment, by orifices 17, 18 distributed on this face and of which the edges have been stamped so that they project outwards from the U. In another embodiment of the invention, the bars 3 or one of these bars have an L-shaped profile, the vertical wall L being located on the outside of the device so

  come to press against the flanges 11, 12.

  FIG. 2 illustrates a positioning embodiment of a spool of continuous flexible material with a protruding mandrel obtained with two devices conforming to FIG.

  the invention and shown in FIG.

  Thus, a device 1 according to the invention is disposed on a support base 19 such

  than a palette. The spacing between the bars 3, 4 has been previously set.

  Two flanges 11, 12 comprising an oblong opening 20, 21 have a square shape, one of the sides of the square being disposed in the housing formed by the U-shaped bars 3, 4. Thus, the device of the invention holds in position the two

  flaccid by their lower side.

  The coil is then placed between the two flanges, the ends of the mandrel

  overflowing coming to rest on the bottom of the oblong opening of each flange 11, 12.

  In the illustrated embodiment, a second device 1 according to the invention is disposed on the upper sides of the flanges 11, 12. Thus, the assembly formed by the two flanges 11, 12 and the two devices I constitutes a rigid frame securely supporting the reel. In addition, by the combination of the weight of the coil and the asperities 17, 18 formed on the bearing face of the device 1 of the invention, the sliding of this assembly on the pallet 19 is made very difficult. It will be the same for a pallet stacked on this assembly and which will rest on the bearing faces of the upper device 1 comprising

also asperities.

  To recover the coil, simply remove the upper device 1 and after gripping the coil by the mandrel, remove the oblong openings of the flanges to take it to a position of use. The positioning and holding devices 1 are then available to receive a new coil, or be returned to

reels supplier.

  With the devices of the invention, it is therefore possible to position and maintain

  1 5 coils on pallets and to store them stacking on several heights.

  When the reels have to be transported, it is better to secure the whole

  devices 1, flanges 11, 12 with the pallet 19 by strapping.

  Advantageously to ensure the protection of the coil, a flexible envelope is arranged around it, a second protective envelope can be arranged around

of the coil / pallet assembly.

  FIG. 3 illustrates an assembly similar to that of FIG. 2 but with flanges 22, 23 adapted for flanges with a flaring mandrel. These flanges 22, 23 also of square shape comprise only a central orifice of diameter close to that of the mandrel. These flanges are mounted on the ends of the mandrel either by interlocking if they comprise a shoulder forming a cylinder on one of their face, or by introduction of tubes 24 provided with a collar, called cups, in the central orifices, the tube fitting in the mandrel and the collar coming to bear on the outer face

flask.

  In the illustrated embodiment, the cups 24 are held in place by rods 25 disposed between the lower and upper devices 1. These rods are removably mounted on the devices I by interlocking their ends in

  housings 26 provided on the bars 3, 4.

  Of course, other means of blocking the cups can be used without

  to do this depart from the scope of the invention.
