Definitions

  • the present invention relates to the field of handling and relates more particularly to a burden of the type comprising several superimposed layers of unit charges and at least one link encircling all of the layers, one of said layers comprising at least one free space which has an elongated shape in a direction parallel to the axis of the loop formed by the link and which is overlapped transversely by said link.
  • the present invention is particularly, but not exclusively, applicable to burdens whose unit loads consist of bags filled with bulk material. Frequently, such unit charges must be stored in large quantities in warehouses before being distributed and used. Generally, the bags are transported by truck or wagon to the warehouse where they are unloaded and grouped into bundles each comprising several superimposed layers of bags, which are surrounded by at least one link. Each bundle thus made is then taken up and transported by a forklift truck to the place of storage where the burdens are arranged one beside the other and one on the other so as to form a stack comprising several contiguous "walls" , each wall itself comprising several contiguous columns of burdens. Usually, the loads are handled using a pallet or a specialized gripping system.
  • the main object of the present invention is to remedy these drawbacks by providing a burden of the type defined above, having a structure such that it is possible to produce columns of burden having great stability and great height, and this without use. pallets.
  • the burden according to the present invention is characterized in that said layer comprising at least one free space is the base layer, and in that the link has a low tension. That is to say a tension such that the burden is not deformed appreciably compared to an unrelated state, but sufficient however to give and maintain the required shape of the burden
  • Bundles are already known which have in their base layer one or more free spaces suitable for receiving the fork leg (s) of a forklift and allowing the handling of the bundles without pallet (see in particular US Patent No. 3,788).
  • the cohesion of these known burdens is obtained not by one or more links, but by an envelope, generally made of heat-shrinkable and heat-shrinkable plastic, so that, in this case, the problems resulting from the high tension links do not arise.
  • the burden according to the invention can be produced by arranging the unit loads of the bare layer so as to provide therein at least one free space having a predetermined width and an elongated shape in a predetermined direction, and by surrounding the set of layers with a link having a relatively low tension by forming with the link a loop whose axis is parallel to said predetermined direction.
  • the number of free spaces and their location in the base layer depends on the number and spacing of the branches of the fork of the forklift used to handle the loads.
  • the branch or branches of the fork of the forklift are placed below the link (s) passing under the base layer and longitudinally opposite the corresponding free space or spaces provided in said base layer.
  • the fork leg (s) of the forklift are lifted for gripping the load, they stretch the link (s) by forcing them to engage in the corresponding free space (s).
  • the bags making up the burden are therefore tightly pressed against each other and the burden can be handled safely.
  • the link or links released by the fork leg (s) of the forklift relax.
  • the bags making up the burden can return to their original shape.
  • the loosening of the link (s) which occurs automatically when the load is placed on the ground or on top of another burden allows the products to be bulk contained in the bags and in particular those contained in the bags of the base layer to return to their original place or to closely match the shape of the surface on which the burden is placed.
  • This therefore results in an automatic setting of the burdens on each other, so that it is possible to produce columns of burdens having a high stability and comprising a greater number of burdens than in the case where burdens are used. according to the prior art.
  • the present invention also provides a machine for making bundles having the particular structure described above.
  • the machine according to the invention comprises, in a known manner, a device for making the bundles, a strapping device, an evacuation station and a conveyor device suitable for conveying a burden made from the making device, through the strapping up to the evacuation station, and it is characterized in that the making-up device comprises retractable means for positioning the unit loads making up the base layer of the burden being made, said positioning means allowing, when are in an active position, to provide at least one free space in the base layer of the burden being made, this free space have an elongated shape in a direction parallel to the strapping axis, and also characterized in that the strapping device is adjusted to place the link with a low tension around the load, i.e. a tension such that the load is not deformed so sensitive in relation to an unrelated state, but sufficient however to give and maintain the required shape of the burden.
  • the burden 1 shown in FIG. 1 comprises several layers, for example seven layers, of unit charges 2.
  • the seven layers are surrounded by two links 3 (only one of these two links is visible in FIG. 1, but the two links are visible in Figure 6).
  • Their tension is low, that is to say that it is such that the burden is not appreciably deformed compared to an unrelated state, but sufficient however to give and maintain the required shape of the burden.
  • Each of the two links 3 can, for example, be made from a strip of flexible plastic material about 16 mm in width.
  • the unit charges 2 can for example consist of bags containing a bulk product, for example sugar. In the embodiment shown in Figure 1, the bags 2 have a length which is approximately twice their width.
  • the first layer or base layer comprises two bags which are spaced by a predetermined distance and which are arranged in such a way that their length is oriented perpendicular to the plane of FIG. 1.
  • the second layer comprises three bags, namely a first bag which is shown on the right in Figure 1 and which is arranged in the same orientation as the two bags of the base layer, and two other bags, one of which is visible to the left of the first bag in Figure 1 and which are arranged transversely compared to the two base layer bags.
  • the third layer also has three bags, but in this case the bag which has the same orientation as the two bags of the base layer is placed on the left, while the other two bags which are arranged transversely to the two bags of the base layer are located on the right.
  • the fourth and sixth layers are identical to the second layer, and the fifth and seventh layers are identical to the third layer.
  • the bags 2 from the second to the seventh layers are placed in a well-known arrangement in crossed layers.
  • the base layer has only two bags 2 spaced from one another. There are thus formed in the base layer three free spaces 4 which have an elongated shape in a direction perpendicular to the plane of Figure 1, that is to say in a direction parallel to the axis of the loop formed by the links 3.
  • each bag 2 can have a length of about 800 mm, a width of about 400 mm and a height of about 157 mm. In the case where the bags 2 contain sugar, each bag may have a weight of approximately 50 kg.
  • the burden 1 shown in Figure 1, which has 20 bags. will have a weight of around 1 ton and dimensions approaching the dimensions of the European pallet, i.e. 1200 mm / 800 mm, and a height of around 1100 mm.
  • Such a burden 1 can be handled by means of a forklift equipped with a fork with three branches, each of the three branches 5 having a length of approximately 800 mm and a width of approximately 50 mm and of which the central branch is spaced from each of the two lateral branches by a distance of approximately 530 mm.
  • the load 1 is placed on two suitable supports 6 situated respectively below the two bags 2 of the base layer as shown in FIG. 1.
  • a cardboard tube with a diameter of about 100 mm, a thickness of about 5 mm and a length of about 800 mm can advantageously be placed between the two supports.
  • the advantage of the tube 7 is that when the load 1 is placed on the ground or on top of another load and the fork legs of the forklift are removed, the tube 7 descends to the bottom of the bags of the base layer and relaxes the links 3 while retaining a passage for the central branch of the fork of the forklift for later gripping. During the laying of the burden 1, the links 3 relax, so that the bulk product contained in the bags 2, and in particular in those of the base layer, can spread out and resume its place in the bags.
  • the two bags 2 of the base layer of the upper burden can conform to the shape of the bags of the upper layer of the lower burden, so that the upper burden automatically locks onto the lower load.
  • bundles having the dimensions indicated above, it is possible to produce bundles of bundles comprising up to seven bundles or more and having a clearly greater stability than with bundles produced according to the prior art.
  • the burden 1 described above with reference to Figures 1 and 2 has three free spaces 4 in its base layer.
  • the invention should not however be limited to this number of free spaces. Indeed, the number and the location of the free spaces in the base layer will depend on the type of forklift used, and more particularly on the number and the spacing of the branches of its fork, and also on the dimensions of the unit loads. burden.
  • Figures 3 to 5 illustrate, by way of non-limiting examples, other possible arrangements for the base layer of the burden.
  • the base layer of the burden 1 shown in FIG. 3 has a single free space 4 located on one of the two sides of the base layer which is parallel to the axis of the loop formed by the link (s) 3.
  • a such a burden can be handled using a forklift, the gripping means of which comprise a single branch 5 and an apron 8.
  • the base layer of the burden 1 shown in FIG. 4 has two free spaces 4, which are located respectively on the two sides of the base layer which are parallel to the axis of the loop formed by the link (s) 3.
  • a such a burden can be handled by means of a forklift whose fork has two branches 5 spaced by a distance corresponding to the spacing between the two free spaces 4.
  • the base layer of the burden 1 shown in FIG. 5 also has two free spaces 4, but in this case, the two free spaces 4 are located at equal distances from the sides of the base layer which are parallel to the axis of the loop formed by the link (s) 3.
