Abstract

Vynález spadá do oboru manipulace s materiálem a vztahuje se zejména na paletizaci. Vynález řeší problém vytvoření stohovatelné palety se stohovacími rozpěrkami, zabraňujícími zaklínění nosných patek při stohování tak, aby stohovací rozpěrky byly pevné a nepodléhaly snadno opotřebení a po škození při manipulaci. Problém je řešen tím, že stohovací rozpěrky jsou vytvořeny jako část žlábkovltých výztužných spojovacích žeber, čímž jsou zpevněny. Vynález je vhodný pro výrobu stohovatelných palet lisovaných z nevzlínavé směsi lignitocelulózových vláken.The invention falls within the field of material handling and relates in particular to palletizing. The invention solves the problem of creating a stackable pallet with stacking spacers that prevent the support feet from wedging during stacking so that the stacking spacers are strong and do not easily wear out and are not damaged during handling. The problem is solved by the stacking spacers being formed as part of grooved reinforcing connecting ribs, thereby strengthening them. The invention is suitable for the production of stackable pallets pressed from a non-sticky mixture of lignitocellulose fibers.

Description

The invention is within the field of material handling and relates in particular to palletizing.

The present invention solves the problem of providing a stackable pallet with stacking spacers to prevent wedging of the support feet during stacking so that the stacking spacers are rigid and are not subject to wear and damage during handling.

The problem is solved by the fact that the stacking spacers are formed as a portion of the trough-like reinforcing connecting ribs, thereby reinforcing them.

The invention is suitable for the production of stackable pallets molded from a non-glue lignite-cellulosic fiber blend.

BACKGROUND OF THE INVENTION The present invention relates to a one-piece, compressible, stackable pallet with spreader spacers, using a non-glazing mixture of lignin-cellulosic fibers bonded to a heat-curing binder, with hollow trough feet open upwardly connected by grooved reinforcing connecting ribs.

Such pallets are well known and have proven themselves in practice. They have the advantage that they can be easily stacked in an unladen state, taking up little space because their protruding feet slide into one another. However, this also has the disadvantage that the conically formed lugs jam together when stacked, so that their manual disassembly is difficult. It is impossible to dismantle a stack of such pallets by machine.

To prevent this, pallets on the underside are provided with freely adjusted spacers to prevent the pallets from wedging together when stacked.

The disadvantage of these freely arranged spacers is that they can be easily damaged, provided they are placed on the ground by means of a conveying means. The aforementioned drawbacks are eliminated by a one-piece, stackable pallet with clamping spacers, using pressure from a non-glazed mixture of lignite-cellulosic fibers joined by a thermosetting binder, with hollow trough feet open upwardly connected by grooved stiffening connecting ribs. according to the invention, in that the clamping spacers are formed as a portion of the trough reinforcing connecting rib, wherein the inner cavity of the clamping spacer facing upward is shorter and narrower than the outer foot of the stacking spacer formed on its underside. The advantage of the stackable pallet according to the invention is that the stacking spacer is not formed separately but forms part of the reinforcing rib, so it is much stronger and more resistant to damage. An exemplary embodiment of a stackable pallet according to the invention is shown in the drawings, in which: FIG. 1 is a plan view of one quarter of a pallet; FIG. 2 is a longitudinal section of a stacking spacer; FIG. 3 is a cross-sectional view of a stacking spacer; Fig. 4 is a cross-sectional view taken along line A-A of Fig. 1; Fig. 5 is a section along line C-B of Fig. 1; Fig. 6 is a section along line C-C of Fig. 1; FIG. 1 and FIG. 8 are a section along the line E-E of FIG. 1.

The stackable pallet has one bead 1 at its center and a further 8 bead at its periphery 1. The beads are hollow, projecting downward from the support plane of the pallet as legs and open upward so that when stacking the empty pallets, the bead 1 slides into each other so that the height of the pallet stack is only about one third of the sum of their individual heights, which is a significant saving in space. The individual feet 1 are connected to each other by grooved reinforcing connecting ribs 2 which reinforce the pallet support surface. Further groove-shaped reinforcing connecting ribs 2 extend diagonally from the central bead 1 to all four sides but do not extend to the corner bead 1 but are terminated by the stacking spacer 3.

The shape of the stacking spacer 3 differs from the shape of the grooved reinforcing linking rib 2 in that the outer and inner walls of the stacking spacer 3 are almost vertical, whereas the walls of the stiffening reinforcing linking rib 2 are substantially sloping and open upward for manufacturing reasons. The outer face 4 of the stacking spacer 3 is spaced from the center of the pallet more than its inner face wall 5, so that when stacking pallets stacking spacers 3 meet in the abutment surface 6. Furthermore, the distance of the outer side walls 8 of the stacking spacer 3 is greater than its an inner cavity 7, so that an outer foot 9 is formed which maintains a distance between the stacked pallets sufficient to lock the beaded legs 1 together. This allows mechanized dismantling of the stack of pallets.
