Definitions

  • the invention relates to a wooden packing frame according to the preamble of the claim 1.
  • Wooden packages of goods are common. They are in general square boxes which comprise a bottom, a lid and 4 side walls and they are typically made of lumber, veneer, OSB- or other wooden board. In many cases the package should not need to have side walls and a lid, but it is enough that it only has a bottom - in other words it is a pallet.
  • the goods can be on the pallet as such or they can be bound for example with bands, glue- or wrapping film or the like.
  • pieces of lumber or the like can be used. Almost always there have to be handles or cavities at the bottom of the package so that the package can be lifted ⁇ with the help of a forklift truck from underneath the bottom of the package.
  • handles or cavities have to be high enough, usually at least about 50...70 mm so that the forks of the truck fit underneath the package.
  • the packages have to be cheap. They are almost always for single use and thus they have to be easily disposable. Such packages which have 6 sides are very expensive, such packages then again, which only have a bottom, are in many cases not strong enough or they don't give the needed protection to the goods.
  • This invention relates to such a wooden package which is a kind of intermediate form of a wooden package and of a pallet. It is cheaper than a box, but as regards packing of the goods, more reliable and more complex than the pallet.
  • Such goods are among others: pipes, logs, balks, building boards, lumber, glassware, big goods, which don't have to be protected from above or from the sides with a board, but must be attached reliably to their bottom and possibly have to be protected from the sides and from above from impacts or they only are protected from the weather from above and sides, goods piled on top of each other which can slide in relation to each other and such quite big goods which are not easy to be piled on top of each other.
  • Such packages are in this case either the pallet type packages and the goods are additionally attached with bands or to some extent wooden frames, which have nail board joints, are also used.
  • Current packages have for example following problems: - The pallet type packages are not suitable for packing many goods, like pipes, balks, or the like because these kind of goods cannot effectively be tied to the bottom with the bands or the like.
  • the pallet type packages are also not good for such goods which can slide in relation to each other or which are not easy to be piled on top of each other.
  • the nail board makes the wooden frame difficult to dispose.
  • the frame which has been joined with the nail board is in many cases so weak or unreliable that in addition to that bands have to be used which increase the costs, the work and the amount of the disposable waste.
  • the nail board extends in many cases outside the wooden parts and can damage the goods to be packed or the protective film of the package or the like.
  • the nail board cannot endure variation in dampness, but may come loose from the wood already after a couple cycles of getting wet and dry. - All the parts of the nail board frame must be of the same thickness.
  • the basic solution of the package is to provide a frame and it thus binds the goods efficiently to their bottom and prevents the goods from sliding in relation to each other.
  • the packing frame consists of both moment-stiff finger glued joints and also jointed or nearly jointed joints which are made usually only after setting the goods into the package.
  • the jointed joints are simple and easy to manufacture, but the moment-stiff joints require special equipment and thus they usually are pre-manufactured.
  • the package forms a strong frame which is essential when the goods to be packed are not easy to be piled on top of each other, like pipes, balks, etc. - At least the moment stiff joints are made with glue joints, especially with finger glue joints which are considerably cheaper and also stronger than nail boards.
  • the strength of the glue joint is nearly the same as the hardness of the wood, usually at least about 50 % of the hardness of the wood so that the dimension of the wood and also the packing capacity is small.
  • the glue jointed package is easy to dispose by for example burning or chipping.
  • the glue jointed frame is strong enough as such and reliable so that bands are not needed, at least they are not needed to strenghten the frame or the bands are used only as one part of the frame, usually only as the top part, but sometimes also as a top or a side part.
  • each part can be adapted according to needs. Usually the top part and the side parts are thinner but wider than the bottom part. - The glue jointed frame endures well dampness and the variations of it.
  • the glue jointed frame can be assembled at least partly only after setting the goods into the frame or on top of its wooden bottom.
  • Figure 1 shows a typical packing frame into which pipes have been packed shown as a rear view of the package.
  • Figure 2 shows a package of pipes according to the figure 1 shown as a side view.
  • Figure 3 shows different variations of the package.
  • FIG 1 there is a packing frame which comprises a wooden bottom 1, wooden sides 2 and 3 and a wooden top 4.
  • pipes 5 have been packed into the frame.
  • the height a of the wooden bottom is usually adapted at least so high, usually to 50 - 70 mm, so that the fork of the truck fits underneath the package.
  • the thicknesses of the wooden sides 2 and 3 and the thicknesses b and c of the wooden top 4 are adapted according to the strength requirements, usually they are smaller than a.
  • wooden sides are wider than the wooden bottom - in other words d > e.
  • the joint of the wooden bottom 1 and the wooden sides 2 and 3 is made with the finger glue joint by performing the moulding 7 so that it isn't parallel with the fibres of the wooden parts to be joined.
  • a strong joint can be achieved also in a way that the moulding is performed parallel with the wooden parts to be joined, but the fingers are long, most advantageously lengthwise at least 30 % of the thickness of the wood to be moulded.
  • the moulding path is a straight line which usually is the most advantageous way of processing.
  • a strong joint can be achieved so that fingers can be seen at the inner corner in place 9 at the side of the thick wooden bottom (the left bottom corner) or at the side of that wooden part which is stronger.
  • An alternate moulding is shown at the right bottom comer.
  • the moulding path may also be curved or moulding can be carried out in such a way, for example in the way described in the publication WO2006/056652, that fingers don't cannot be seen.
  • the joint between the wooden top 4 and the wooden sides 2 and 3 can be formed in a corresponding way, but in this case the joint has been carried out so that the wooden top 4 can easily be joined only after setting the pipes to a pre-manufactured U-shaped frame.
  • this kind of joint is formed as a finger joint, it is small regarding the total strength of the frame considering cross-sections and the strength of the bottom corner and at least almost jointed.
  • glue is glue which solidifies quickly, for example hot-melt glue.
  • jointed joint is formed as its simpliest in a way that the ends of the wooden tops have been attached with binding tread or with a band in the wooden frame of the U-shaped form.
  • FIG. 1 one basic type of the frame according to the invention is shown: U-shaped frame, into the goods are packed and a wooden top which binds the frame. Often the attaching of the wooden top would be simplier and cheaper to carry out in such a way that no glue is needed in the joint.
  • This kind of solution is for example such a solution that the joint is a conventional dovetail joint.
  • Another, usually even a better solution is such a solution in which the wooden top 4 is thin, for example a piece of veneer with a thickness of 12 mm, OSB-board or also a pasteboard or the like, to the ends of which a hole is made.
  • Figure 2 shows the package as a side view.
  • the package has 2 frames, but it can have some another amount of them, too.
  • Figure 3 shows some other implementation forms A, B, C, D, E, F, G and H.
  • the stiff part which can endure moment stress, like lumber is marked with a thick line and the part which cannot endure moment stress, like a band, string or the like which is attached to the frame or surrounds it, is marked with a thin line.
  • the stiff joint which can endure moment stress is marked with a black circle and the joint which cannot endure moment stress with a white circle.
  • the frame C is open, but it can be thought that the top ends of the wooden sides are attached to each other with joints because the torsion of the other end does not become conveyed to the other end.
  • One advantageous package consists of parallel L-shaped pieces or L-shaped pieces which are located a distance away from each other according the H-shaped model, in which the location of the side part varies at the various sides of the package.
  • a special benefit of this kind of package is the fact that the L-shaped piece can be considerably smaller than the actual package so that material can be saved and one L-shaped piece is applicable to several package sizes.
  • this kind of package there usually also has to be a band so that the package is similar to the D-type, but the stiff joint is only at one corner of the frame.
  • This kind of package is implemented advantageously in such a way that the wooden part and the band or a string attached to it, usually to the wooden bottom are pre-manufactured.
  • the wood can be replaced a lot with the band which is advantageous because the price of one meter of the wooden part is usually at least 10 times so much in relation to the corresponding price of the band.
  • the pipes are usually packed on top of each other and parallel to each other.
  • the overlapping packing would lead to a packing capacity which is nearly 10 % smaller.
  • the pipes are not packed overlapping to each other because this way of packing causes considerably large stress to the packing frame.
  • the package according to the invention is so strong that it also endures the overlapping packing of the pipes.
