HANDLING PALLET OF THE TYPE CONSTITUTED BY A CARDBOARD PLATE 10 ASSOCIATED WITH PLOTS 1 FORMING FEET, CHARACTERIZED IN THAT THE SAID PLATES 1 ARE GLUED 11 ON THE LOWER FACE OF THE CARDBOARD PLATE 10. APPLICATION: HANDLING PALLET.

Description

HANDLING PALLET IN CARDBOARD.

  The invention relates to a new type of pallet

cardboard handling.

  As is known, a handling pallet is a floor plate for storing and handling loads by means of trolleys.

forklifts.

  In a first embodiment, these pallets

  were formed of two parallel floors, gener-

  rarely made of wood, connected to each other by spacers.

  This was a practical but heavy technique

bulky and expensive.

  In a second embodiment, the pallet is formed by a board plate forming a floor

  resting on supports or feet or more precisely

  on the blocks in order to allow the passage of

  forks of the forklift In a form of

  widespread use described in the French patent.

  72/02 655, cut in the floor of the openings

  and insert into these apertures plastic studs forming a foot. To do this, the top of these studs has a double crown.

  in which, by turning, the edges of the

  cut in the cardboard box Although this solution

  There are a number of disadvantages which limit its practical use, namely: firstly, economically, this technique of cutting openings requires large series; on the other hand, the interval between the two grooves of the pad being fixed, the cardboard can have a specific thickness, which considerably limits the versatility of this technique; finally, the setting up of the studs by screwing is always a delicate operation, even if it is automated without counting that after use, these studs do not

  2- The invention overcomes these disadvantages It relates to a handling pallet of the type consisting of a cardboard plate associated with studs forming feet, which

  on the one hand, economical to manufacture, easily adapted

  table for small series and cartorns of different thicknesses and does not require any specialized equipment

for its elaboration.

  This handling pallet of the type constituted by a Carton plate associated with studs forming feet, is characterized in that said studs are glued on

  the underside of the cardboard plate.

  Advantageously, in practice: the pads are injected plastic, such as PVC, polyethylene, polypropylene, polystyrene, loaded or not with glass fibers; these pads have an appropriate shape, including

  truncated cone or even better tetragonal (square, rec-

  tangle) so as to offer the best surface area

  te and the best bonding surface

  these pads are hollow to allow a stock

  Convenient ge with large rims in the shape of an overflowing crown to, on the one hand, facilitate stacking and, on the other hand, provide a larger surface area for gluing the glue, intended to secure these pads with the cardboard plate. a wet material intended to be passed with a brush or roller, therefore requiring no specialized equipment, fast drying, for example of the order of one minute; it is essential that this

  glue does not get too much water so as not to penetrate

  cut the cardboard and not spread inappropriately and beyond the necessary surface; the cardboard is chosen according to the required performances (corrugated, multi-corrugated or multi-ply cardboard).

  In practice, the pads have a tapered shape,

  at the top, at least for the most part, but open at their base and comprise a large crown intended to be glued to the tray board.

  the shape of these studs has a transverse cross-section

gonal, but of pyramidal form.

  If more generally, the carton has the form of a flat plate, it can also be constituted by the bottom plane of a box including cardboard, such as a

American box.

  In an advantageous embodiment, the locations of 2 pads are predetermined, in particular by simultaneous printing on the cut on the back side.

cardboard.

  In this way, when one wishes to set up

  the studs, their proper location is easily i-

  Identified and does not require any specialized personnel.

  In another advantageous embodiment, the surface

  outer ring of the studs is coated with an adhered

  sive covered in turn with a protective sheet, such as a silicone paper that is removed during the installation of

pads on the carton.

  The manner in which the invention can be realized and the advantages which result therefrom will emerge more clearly from the following exemplary embodiments given as

  indicative and not restrictive in support of the figures

  secured. FIG. 1 is a sectional view of a compliant stud

to the invention.

  FIG. 2 is the view from above

from this same plot.

  FIG. 3 shows in section a carton associated with

such pads.

  Figures 4 to 7 show different forms of

  (4 and 6) and their association

  to studs according to the invention (Figures -5 and 7).

  FIG. 8 shows another improved embodiment in which the outer face of the

  crown is-coated with an adhesive material.

  Referring to FIGS. 1 to 3, the characteristic stud 4 - according to the invention (1) is made of injected plastic (see FIGS. 1 and 2) and comprises a body (2) of tapered shape closed at its base (3). ), except that he

  has a weak or Verture (4), intended for evacuation

  This stud is open at its upper part in its

  center (5) and has a broad neck rim

  Ronne or analog To allow stacking, it is necessary that the internal and external conicity of the studs

  almost identical In the same way, the diameter of the opening

  (5) must be larger than the outside diameter of the base (3) to allow the bottom to pass through the top. However for the convenience of the drawings, these rules have not been

totally respected.

  The tapered shape of rectangular section and pyramidal shape is reinforced by beams (7,8 and

  9) directly molded (see Figure 2).

  By way of example, a plot having the following

  following dimensional characteristics: height-: 180 mm thickness of the flanges (6): 2 mm thickness of the beams (7,8,9): 2 mm thickness of the walls (2) and (3): 2 mm width of the rectangular base: 80 mm length of the opening (5): 85 mm diameter of the crown forming the flange (6): mm. These studs (1) are fixed by means of an adhesive (11)

  on the back side of the floorboard (10)

Figure 3).

  As already stated, in this advantageous embodiment, the pre-cut cardboard, for example 800 x 1200 mm, has four (FIG. 6), five (FIG. 4) or more markers (15) previously printed. These markers (15) are located at less at the four corners of the cardboard, for example at a distance of between 50 and 100 mm from the angle of each of the clays and possibly in the center. On these marks (15), it is placed by hand, that is to say brush or roller, a wet glue highly viscous, appropriate, quick drying Then place on the surface and glued (11) the studs

(1) appropriate (Figure 5,7 and 9).

  In an advantageous embodiment shown in FIG. 11, the upper face of the rim (6) is coated with a suitable adhesive material, such as, for example, hot melt adhesive, acrylic resin, elastomer

  solvent (17), in turn coated with a foil

  Tector (18), such as silicone paper When one wishes to use this pad, simply remove the sheet

  silicone paper (18), then apply the coated side

  kills adhesive (17) on the back side of the carton (10)

  to bring about accession, especially in

res (15).

  If in the embodiment described, the section of the stud is of tetragonal shape, it goes without saying that this shape may be different: polygonal, cylindrical, conical, etc. Similarly, if the cardboard (10) has the most generally

  the shape of a flat plate, this carton (10) can also

  that is to say the handling in the form of pallets of this box thanks to the forks of forklifts, the invention has many advantages over the known embodiments to date can be mentioned: the ability to adapt to all thicknesses of cardboard which was not possible with the current techniques described in the preamble; the fact that it is much easier to paste

  a cardboard block than screwing feet to palet-

  or put in place the studs in -6- openings previously cut, as described in the preamble; the absence of a hole in the cardboard plate, which does not reduce the mechanical performance of this plate;

  easy and separate storage of studs and

  cardboard; the possibility to realize small series, which did not allow economically the current techniques

  the ability to manipulate in puck form

  American coffers, which was not possible until then. In this way, this invention can receive

  very varied applications in the field of

  palletization: either in the form of pallets themselves (flat sheets of cardboard);

  either in the form of boxes (boxes of cardboard).
