Description

The papery pallet

Technical field

The present invention relates in the vehicle borne process such as fork truck, be used for the pallet of bearing goods, this pallet also can be used on other similar or more special transportation means, uses paper material capable of circulation to process.

Background technology

Usually, pallet adopts wooden the manufacturing, to reach the requirement of high bearing capacity.Yet wooden pallet has the some shortcomings part, and main shortcoming is a weight.Compare with the papery pallet, although wooden stronger on intensity, manpower goes to move wooden pallet if desired in transportation, has just brought problem.Except weight, wooden pallet is also shorter relatively on useful service life, when they are considered to be used further to carrying and shipping goods, will be recovered and dispose.In addition; Wooden pallet need be carried out some particular processing operations; To prevent the diffusion of insect,, so just improved the production and the assembly cost of wooden pallet such as the kind of stipulating in insect, mouse, bacterium etc. and the laws and regulations of other bases by grain and agricultural organization's issue.

The major defect of papery pallet is that load-carrying capacity is relatively poor and intensity is lower, if these deficiencies can be solved, the inferior position of wooden pallet can be overcome by the papery pallet.In existing technology, extensively known is to adopt corrugated cardboard or couch board to make pallet.The benefit of papery pallet is recyclable, more economical and more environmental protection.Yet many living manufacturers have spent great energy on above-mentioned two subject matters of its papery pallet of producing of solution.In the face of more complicated pallet structure, in order to produce and assembling obtains more crash-resistant more by force papery pallet, other manufacturers feel difficult.

Such as, international patent is WO 95/29849 a disclosed prior art, has showed a kind of pallet of processing with laminated paper or cardboard.The invention that said publication is described has related to a kind of pallet, and it has the pedestal cross section and the platform that are mainly formed by rectangular tube.Said pedestal cross section pipe is further supported by some foursquare paper tubes, forms a hard pedestal, and platform is the hollow paper tube that is formed by two U type paper beams simultaneously, inlays each other to form.The platform of said papery pallet is supporting the handling load of wanting.Because the platform of said papery pallet is a hollow, solid inadequately, therefore in transportation,, then flatten easily if the weight of institute's bearing goods is bigger.

The patent of international patent WO 2008/144854 discloses another kind of papery pallet, is made up of some longeron parts that intersect in length and breadth, has formed platform and some strut members at a top.Shown in said patent public technology, the cross sectional shape of strut member possibly be square, circle or U type.Similar with the disclosed prior art of preceding text, papery pallet of the present disclosure has the top, or perhaps a terrace part, and it merges the hollow, rectangular part that forms by the U type spare that intersects in length and breadth or two U type spares and constitutes.Therefore, perhaps said top can not provide enough intensity to support heavier goods.

Another international patent is that the patent of WO 94/02366 discloses a kind of pallet of being processed by recyclable millboard, and it is formed by two-layer crisscross beam, is covered with corrugated board above every layer.Said paper beam is actually the hollow paper tube that is formed by a corrugated board parcel.The mutual adjacent distribution of said hollow paper tube is reaching supporting role, and said corrugated board is fixing on the throne with them.Said like this hollow paper tube can provide enough intensity and fastness for pallet, but in beam, uses continuous hollow paper tube can increase the weight and the cost of said pallet.In addition, this arrangement of bearing-type hollow paper tube means, can only adopt fluting board that the method that they wrap up is located them.Therefore, the intensity of this pallet depends on said paper tube fully, if take wherein paper tube away, can have influence on the intensity and the fastness of said pallet structure.Another shortcoming of this papery pallet is, just make with the wrapper plate of which floor corrugated board and so at its top that is used to bear shipping goods weight.Although it is as shown in the figure; The said paper beam that is positioned at the upper strata is separated from each other basically arranges, and highly also with to be positioned at lower floor's paper depth of beam identical, the upper paper beam is arranged like this; Not as a platform or top; But be used to support stressed, can make said open pallet become a four-way pallet like this, rather than two to pallet.

For these shortcomings of papery pallet design-calculated before solving, the present invention will provide a kind of papery pallet can get rid of or reduce the mentioned problem of preceding text.
