Definitions

  • the latter manufacturing method forms the basis of the pressure container being known from Norwegian patent No. 170 552, wherein besides there is described and shown an outer, protective sheath to serve for resisting fire or heat influence.
  • the patent publication describes end elements formed as a top disc and a bottom element, both being secured to the container structure using said fibre winding.
  • the present invention is aimed at a new and improved container construction which to a large degree takes into consideration the conditions during the production, so that the complete containers may be produced rationally and reliably with a high quality on the product. In this context the winding process with fibre strengthening per se is of great importance.
  • the invention also includes a method for producing such pressure containers .
  • the liner preferably has an rotational symmetry and may be produced by blow-moulding, injection moulding or rotational moulding. It is also advantageous to use such plastic materials both in the liner and in the layer being wound, as the combined structure of the container walls is transparent or translucent. It is also practically suitable to provide a protecting sheath which more or less envelope the pressure container.
  • Such a complete container design is described in the simultaneously filed patent Norwegian patent application No. 97.0449 (PCT/NO98/00026) .
  • Figure 1 shows an example of a pressure container according to the invention mounted on a rotational piercer, in which the fibre winding is considered to be finished, and Figures 2-6 show different embodiments of the supporting elements by the bottom of the pressure container, for use in the fibre winding.
  • Figure 1 shows an axial section of an example of a pressure container during one state of the production process.
  • the wall structure in the container comprises an inner liner 1 having a finished fibre reinforcement or winding in an outer layer 2 covering the cylindrical main body or mid section of the container, as well as the bottom and top sections.
  • On the top at the left in figure 1) a central opening 20 is shown with a surrounding boss 4, which in use of the pressure container among other thing may serve as a mount for a coupling and valve unit as is known from container e.g. for propane or butane.
  • the inner liner 1 may be assembled from two or more separate injection moulded parts, which are welded together in a plane marked with 3.
  • a reinforcement rib or wall 5 is shown stretching from the bottom construction in the container to through an axial part 5A and further through the welded connection at the plane 3 and to a continuation all the way to the boss 4 on the top of the container.
  • Such ribs or walls 5, 5A lay in principle in radial planes and may be provided in higher or lower numbers, evenly distributed around the circumference of the container.
  • a supporting element 9 by the bottom of the container which plays an important part during the winding process .
  • such a supporting element can have a valuable reinforcement or stiffening effect in the bottom construction, especially in relation to the ribs 5 stretching into and may be fixedly joined to the supporting element .
  • This supporting element 9 er provided with a centring hole 9A adapted to receive a preferably conical or pointed end 13 on a rotational piercer 11 stretching axially the whole container and out through a holding piece 12 mounted in the boss 4.
  • a machine or production equipment performing or aiding the mentioned winding on the outside of the liner 1.
  • the winding is supposedly finished, as the resulting outer layer 2 is in place.
  • the winding process per se may be of any known type, and needs no further explanation here. An important point in this context is, however, that with the described support of the liner 1 on the piercer 11 it may, using the machinery 10 set the liner into the required rotary motion for the winding to be performed.
  • the fibre reinforcement being winded on may in a known way be provided with an adhesive which thereafter is allowed to harden.
  • the hardening may advantageously be performed using heat treatment in a subsequent operational step, as the fibre winding may be done in a cold or warm condition.
  • the support for winding as shown in figure 1 may according to the invention also be exploited for a precise length calibration of the liner 1 while this is somewhat deformable. This is done by adjusting the length of the piercer slightly, so that a stretching force between the bottom construction with the supporting element 9 and the top section of the container with the boss 4. What may be obtained with this method is a certain lengthening of a slightly too short liner 1 in the axial direction, all of the produced liners thus being calibrated to the exact same axial length. This length calibration should preferably be performed before the actual winding of the layer 2.
  • FIG. 1 Another advantageous use of the supporting arrangement in figure 1 is the use of the piercer 11, with ancillary holding device 12 and possibly a moveable equipment unit 10, to transfer the enwrapped container 1,2 from the winding station to a subsequent operation step, e.g. a hardening step as mentioned above.
  • Figure 1 shows an example of an embodiment of the support element 9 with ancillary centring organ shaped as a conical hole 9A.
  • the figures 2-6 illustrates other possibilities, each under different conditions being advantageous when producing different pressure containers.
  • Figures 2 and 3 show support elements 29 and 39, respectively, being integrated parts of the corresponding liner, the liner in these embodiments preferably being produced by injection moulding.
  • Figure 2 shows the previously mentioned rib or supporting wall 5 and also the outer, winded layer 2.
  • the support element 29 is, the same way as the element 9 in figure 1, produced inside the liner 1, and has a centring hole 29A which may be threaded in order to cooperate with the corresponding end part of the rotation piercer with corresponding threading. This ensures the fastening of the support element and thus the whole liner for the winding process.
  • figure 2 and figures 4, 5, and 6 are based upon a centring organ in form of a hole
  • the alternative in figure 3 is based upon an integrated support element 39 extending out into a conical point or tip 39A adapted to cooperate with a rotation piercer having a complementary, cup-shaped end part adapted to lay on the outside of the conical tip 39A.
  • Figures 2 and 3 show the support elements 29 and 39 inside the liner 1, but in figure 4, 5 and 6 support elements are shown being positioned outside the liner l. This means that the rotational piercer or spindle is not brought into the inside of the liner 1, but axially from outside (i.e. from the right in these three figures) .
  • These outer support elements 49, 59, and 69 are fastened to the pockets 48, 58 and 68, respectively, in the corresponding liner.
  • the support element 49 in figure 4 has a relatively deep plug-shaped form with a conical hole 49A.
  • the winded layer 2 also have in the finished pressure container a corresponding hole 42, possibly as a direct result of the winding being performed completely against the end part of the rotation piercer in this area.
  • the hole-combination 49A-42 in the bottom construction of the container does not represent a weakness or any other disadvantage in the resulting product.
  • the example in figure 5 has a relatively large resemblance to the one in figure 4, but the support element 59 has somewhat less depth and has a cylindric hole 59A with threads, corresponding to the hole and the threads 29A in figure 2. Also the outer part 52 of the hole is in the winded layer 2.
  • FIG. 6 shows a more plate-shaped support element 69, than the plug-shaped elements in figures 4 and 5.
  • the pocket 68 in the liner 1 is correspondingly relatively wider in the radial dimension, but is, similar to the pockets 48 and 58, connected to or integrated in the support ribs 5. To what degree such an integrated structure is preferable and suitable for rational production depends also on how the liner 1 as a whole is produced.
  • the examples in 4,5 and 6 are primarily based upon production of the liner using blow-moulding or rotational moulding.
  • the holes 62 and 69A in figure 6 have shapes corresponding completely to the holes 42 and 49A in figure 4.
  • the holes shown in figures 2, 4, 5 and 6 have either inner threading as mentioned above or a profiled or edged shape securing rotational coupling to the piercer. It may also be correct to have a rotational locking between the supporting elements in the embodiments in figures 4, 5 and 6. This type of locking may suitably be provided by giving the elements 49, 59 and 69 a basic shape being not completely rotational symmetric, e.g. polygonal, and the corresponding pockets receiving these elements having a complementary shape.
  • FIG. 6 A special variant of such a rotational locking is shown in figure 6, where the pocket 68 and the element 69 both may essentially have rotational symmetry, but by 66 a recessed segment in the supporting element 69 is shown, as the recess, after positioning of the element 69 in the pocket 68, is filled with e.g. a suitable adhesive to obtain the here described locking.
  • the outer main surfaces stretches essentially in line with the adjacent outer surfaces of the liner 1.
  • the fibre reinforcement layer 2 covers essential parts of the outer surfaces of the support elements.
  • These have, in addition to their supporting function during production, also a reinforcing effect in the bottom construction of the finished pressure containers .
  • This advantageous effect may be of great value even if the supporting element comprises a relatively small part of the total surface area of the bottom construction of the containers .
  • the embodiment in figure 2, and partly in figure 3 is very advantageous in relation to this reinforcing effect. It is therefore suitable as illustrated in figure 2, that the liner has a gradually increasing wall thickness in a part surrounding the supporting element 29, so that this provides good reinforcement .
  • the supporting elements in figures 4, 5 and 6 are produced separately before the enclosing of the respective pockets 48, 58, 68.
  • the elements may be made from metals or similar material being stronger than the material in the liner 1.

Abstract

La présente invention concerne un procédé de fabrication de récipients pressurisés destinés à des fluides tels que le propane ou le butane. Ce procédé consiste à réaliser en matière plastique une garniture intérieure (1) étanche aux fluides et présentant une symétrie de rotation. On utilise à cet effet une technique de moulage par injection, de moulage par soufflage ou de rotomoulage tout en ménageant un orifice central (20) à l'une des extrémités (le dessus) de la garniture. Le procédé consiste ensuite à entourer la garniture intérieure d'une armature de fibres (2) imprégnée d'adhésif et mise à durcir par la suite. En l'occurrence, pendant ou après la réalisation de la garniture intérieure (1), on équipe l'autre extrémité, axialement opposée à l'orifice central, d'un élément support (9) axialement pourvu d'un organe de centrage (9A). La garniture intérieure (1) est montée rotative sur son axe par coopération avec l'orifice central (20) et l'organe de centrage, un pointeau à rotation ou perforateur (11, 13) entrant en coopération avec l'organe de centrage (9A), et la garniture intérieure montée étant mise en rotation pour enrouler l'armature de fibres.
