Description

Removable and stackable pallet, in particular for sheet products

  The present invention relates to the field of packaging and transport of products on pallets,

  in particular leaf products, especially green

  re, and relates to a removable pallet and stackable for this purpose.

  The transport of sheet materials, in particular

  of glass, generally requires the use of

  specially adapted pallets to

  packing leaves laid on slice.

  For this purpose, it is customary to use either pallets with fixed raised edges or pallets with foldable edges against one of the edges of which the sheet products are supported, which are wedged, either with inflatable means or with specially adapted devices which are clamped on said pallets by means of

of straps.

  These known pallets make it possible to satisfy the storage requirements of the products, but

  their maintenance and calibration.

  The processors do not necessarily empty a complete pallet in a single operation, so that the wedging elements become inoperative and that a correct hold against a roll-over of the products in the pallet is no longer ensured. case of pallets with edges

  fixed readings, their large size is very important.

  suitable for empty storage for intermediate storage and transport. The folding pallets made it possible to obviate the disadvantages of these fixed edge pallets by ensuring, for example, a folding of two of their edges around

  corresponding amounts of a third board.

  However, these known folding pallets, which

  allow, of course, a significant reduction in the

  for storage and empty stacking, are of

  complex structure, particularly in terms of

  on the one hand, between the lateral edges and the third edge and, on the other hand, between the third edge and the bottom of the pallet.

  heavy and relatively unfolding and folding

  ciles that could lead to injury

the operator.

  The present invention aims to overcome these disadvantages. Its object is indeed a pallet, in particular for sheet products, characterized in that it is removable and stackable and in that it consists essentially of a bottom with edges slightly

  raised, by two side walls mounted by emman-

  in the corresponding edges of the bottom, by a

  back wall of the products and by a means of

in position of said products.

  The invention will be better understood, thanks to the following description, which relates to a mode of realization.

  preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a perspective view of the pallet according to the invention; Figure 2 is a plan view of the housing means; Figure 3 is a side elevational view of a wedging wedge, and

  Figure 4 is a partial sectional view of an alternative embodiment of the bottom of the pallet.

  According to the invention, and as shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the pallet, in particular for products

  in sheets, is removable and stackable and is essential

  actually constituted by a bottom 1 with edges slightly

  raised, by two side walls 2 mounted by emman-

  in the corresponding edges of the bottom 1, by a rear wall 3 of support products and a means 4 of

  wedging in position of said products.

  The bottom 1, which is provided in known manner with feet 5 indented to allow stacking, has at its corners connected tubular upright elements 6

  between them, on the one hand, at the feet 5 by

  7 and 7 'longitudinal members of profiled elements and, secondly, at the side walls by a sheet 8 extending above the corresponding longitudinal members 7', the longitudinal members 7 'and cross members 7 being, in addition, connected to

  their lower part by a bottom plate 9.

  According to one characteristic of the invention, the bottom 1 is further provided with support profiles 10 for the sheet products, these sections being mounted between

  the sleepers 7 with the possibility of transverse displacement

  sal by guiding on a median axis 11 connected to the side members

  7 'and passing through corresponding holes of said

  spun 10, which rest at their ends on the

  For this purpose, the profiles 10 are advantageously

  cut at said ends.

  Such a mounting of the support profiles 10 allows their adjustment in the transverse direction and an adaptation to the

  length of products to be packaged in the pallet.

  The side walls 2 are preferably

  in the form of symmetrical tubular frames between

  in their mounting position, the amounts of which 2

  in the tubular uprights 6 of the bottom 1 and are

  interconnected by two upper cross members 12 and

  13, the uprights 2 'corresponding to the wall

  of the pallet having an upper part

  ened. The rear support wall 3 of the products is constituted by an upper cross member 14 connected at its ends to two sleeves 15 intended to penetrate the

  the shortened upper end of the corresponding amounts 2 '

  of the side walls 2 and a lower cross-

  16 connected to the top rail 14 through

  medial of fixed central supports 17 and mobile lateral

  18, this lower crossbar 16 being supported at its ends

  against scheduled stops on tubular

6 correspondents of the bottom 1.

  The free ends of the pillars 2 'of the

  side walls 2 and sleeves 15 have a reinforcing

  20 for cooperating with the notch of the feet for stacking. The movable lateral supports 18 are preferably mounted on the upper crosspieces 14 and lower 16 with the possibility of sliding in grooves 21 cooperating with lugs (not shown) provided on said supports 18 Thus, it is possible to adjust

  front support of sheet products, in

  timale, the lateral supports 18 being movable on the cross members 14 and 16 as a function of the length of said products. The means 4 of wedging in position of the products

  advantageously consists of at least one corner of

  22 mounted on an axis 23 provided at its ends with a device 24 for mounting and holding adjustable on a setting means 25 provided on the lower rails

  13 side walls 2 (Figures 2 and 3).

  For this purpose, the adjustment means 25 provided on each lower cross member 13 is preferably made of

  this, by a rack and the device 24 for mounting and adjustable holding is in the form of an arm provided at each end of a stud 26 for cooperating with a notch of the rack forming the means, this arm being mounted on the corresponding end of the axis 23 with offset, so that the distances of the studs 26 to the axis are different Thus, it is possible, before definitive support of the wedging wedges 22 against the stack of stalling products, to determine the nipples 26 of the arms of the two ends of the axis 23 to be inserted into the notches of the rack forming the adjustment means 25 Indeed, by rotation of the axis 23, it is possible to approximate or to remove the wedging wedge (s) of the products to be stalled, so that the arms of the device 24 extend substantially horizontally when the corner (s) 22 are pressed against the stack of products. that the corners 22

  tend to be closer to

  each vibration or jolt, so that

  rigging is ensured perfectly.

  For the release of the products, that is to say to unlock the corner or corners 22, just pull on the axis 23, which has the effect of pivoting the latter around the studs 26 cooperating with the notches of the rack forming the adjustment means 25, causing a

  detachment of said corners 22 of the product stack.

  The back wall 3 support products can

  be lodged, after dismantling, in the back 1 between the

  the 8 connecting the tubular uprights 6, the side walls

  2 being then placed above said wall 3, also between the side walls 8 Moreover,

  the means 4 of setting in position of the products is also

  placed between said sheets 8, the corners 22 are

  within the intervals respectively

  be the central supports 17 and side 18 of the wall 3,

  or between the plates 8 and the said lateral supports 18.

  The pallet according to the invention can be completed by a lateral locking device of known type, namely inflatable or mechanical consisting of two bars extending along the side walls 2

  and guided on these with the possibility of pivots-

  in the direction of the products to be stalled and locked in position, by means of a slider or other such device is not described in more detail, being

already known from the prior art.

  FIG. 4 of the attached drawings represents an alternative embodiment of the invention, in which the

  bottom 1 is provided with support profiles 10 for

  sheets of paper cooperating, by the ends of their core, with notches 27 of one or more profiles

  28 provided on the inside of the sleepers 7, the

  bearing strips 10 extending externally being provided

  each of at least two parts 29 protruding outwards

  and upward at an acute angle, intended for

  co-operate with a wedging bar 30 Thus, it is pos-

  able to adjust the support parts 10 according to the

  length of the products to be packaged and wedged laterally

  these products with the wedging bars 30, which

  automatically tighten against the edges of

  which prevents any ripping.

  According to another characteristic of the invention, not shown in the accompanying drawings, the pallet may be completed by a closing wall clinging to the

  2 'opposed to the rear wall 3 by means of

  fastening tabs penetrating into the said

  2 ', this wall being further provided with its part

  lower, retaining lugs against the

  this internal corresponding amounts 6 of the bottom 1 Ain-

  if, it is possible to completely close the pallet.

  Of course, this front wall can also be

  in the bottom 1, between the plates 8 and in the clutter

  in height delimited by the amounts 6.

  According to another characteristic of the invention, the support profiles 10 provided in the bottom 1, as well as the support profiles 17 and 18 provided on the rear wall 3 and the wedging bars 30 are advantageously provided with a coating anti-shock felt, rubber or

  analogies, designed to prevent any deterioration of

  on their songs or on their edges.

  Thanks to the invention, it is possible to realize

  a pallet for the packaging of sheet products, particularly fragile products, such as glass, which ensure stalling and clamping

  In addition, because of the prediction of

  With the use of racks, it is possible to effectively and securely tighten an opened pile of products, so that the risks to date of pile up and destruction of

products can be eliminated.

  Finally, because of the constitution entirely

  removable from the pallet, it is possible to store this

  the last in non-use position, for example for a return transport from the user to the supplier or for intermediate storage, in an extremely small space, which leads to a correspondingly significant reduction in storage and transport costs. In addition, such a pallet does not require any non-reusable or disposable auxiliary element, so that it perfectly meets the protection criteria of

the environment and economy.

  Of course, the invention is not limited to

  embodiment described and shown in the drawings

  nexés Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of equivalent techniques, without leaving

  for all that the field of protection of the invention.
