Description
Stablebart transport- og lagerfat. Stackable transport and storage container.
Foreliggende oppfinnelse vedrører et ved blåsing fremstilt, stablebart transport-og lagerfat av termoplast og med i planet for formskillesømmen på fatets toppflate anbrakte spuns. The present invention relates to a blow-produced, stackable transport and storage container made of thermoplastic and with sheeting placed in the plane of the form separation seam on the top surface of the container.
Ved plastfat av den ovennevnte type, særlig ved fat med stort volum, har det kun i utilfredsstillende grad vært mulig å oppnå sikker stablingsevne og fremfor alt å overholde mål og beliggenhets-stilling av spunsene nøyaktig overfor fatets toppflate under fremstillingen. In the case of plastic barrels of the above-mentioned type, particularly in the case of barrels with a large volume, it has only been unsatisfactory to achieve safe stacking ability and, above all, to comply with the measurements and position of the staves exactly in relation to the top surface of the barrel during manufacture.
Ifyllings-og utluftingsspunser ligger diametralt overfor hverandre på fatets toppflate i nærheten av dennes kant. I kant-området hersker det overfor fatets tilstøtende manteIdeler uensarte-de krympespenningsforhold fremkalt av forskjellig materialfordeling. Etter uttagning av de ferdigblåste fat fra formene, tvinger krympe-spenningene som virker i kantsonen av fatets toppflate, spunsene til å innta en i forhold til fatets midtlinje utad hellende skråstilling. Derved er stableflatens symmetri ødelagt og på den annen side opptrer det i selve spunsen deformasjoner som må fjernes ved omstendelig et-terarbeide. De siste forholdsregler volder særlige vanskeligheter da den tidligere fremstilte spunstapp ikke mer kan kompensere for de under etterarbeidet fremkalte toleranseendringer. Den påkrevde tetthet i lukket blir således ikke oppfylt. Filling and venting sponges lie diametrically opposite each other on the top surface of the barrel near its edge. In the edge area, non-uniform shrinkage stress conditions prevail against the adjacent mantel parts of the barrel caused by different material distribution. After removal of the pre-blown barrels from the molds, the shrinkage stresses acting in the edge zone of the top surface of the barrel force the sponsons to assume an outwardly inclined slanted position relative to the middle line of the barrel. Thereby, the symmetry of the stacking surface is destroyed and, on the other hand, deformations occur in the sheet piling itself, which must be removed by extensive rework. The last precautions cause particular difficulties as the previously produced sheet pile can no longer compensate for the tolerance changes induced during the finishing work. The required tightness in the closed is thus not met.
Oppfinnelsens formål er under bibehold av en maksimal stableflate ved fatets øverste bunn, å tilveiebringe en gunstig an-bringelse av spunsene under forutsetning av beliggenhets-og formsta-bilitet under fremstillingen. Formstabiliteten, spesielt i de i tet-nings funksjonen deltagende spunsområder, må være innenfor slike gren-ser at enhver etterbearbeidelse er overflødig. The purpose of the invention is, while maintaining a maximum stacking surface at the top bottom of the barrel, to provide a favorable placement of the sheet piles under the assumption of location and shape stability during manufacture. The dimensional stability, especially in the sheeting areas participating in the sealing function, must be within such limits that any post-processing is redundant.
Dette formål oppfylles ifølge oppfinnelsen ved at de mot fatmidten vendte yttervegger av de i fordypninger i stableflaten anbrakte og med deres åpningskanter til stableplanet utragende spunser, i den øverste sone er forbundet med fatets toppflate over en ribbebro. According to the invention, this purpose is fulfilled by the fact that the outer walls facing the middle of the barrel of the piles placed in recesses in the stacking surface and with their opening edges projecting to the stacking plane, in the uppermost zone are connected to the top surface of the barrel via a rib bridge.
Ved denne forholdsregel oppfanger ribbebroene de mot-satt virkende krympespenninger og tvinger spunsene til parallell sym-metrisk beliggenhet om fatets akse slik at spunsåpningsplanene flukter med stableplanet i fatets toppflate. Da et oppstablet fat skal ha en størst mulig stableflate til rådighet, danner kantene av de i fordypninger liggende spunser en del av stableflaten. Skjevstilling av spunsene ville fremkalle ujevnheter i stableflaten og derved hindre en veltesikker stablestilling. Denne risiko er utelukket med den nye forholdsregel. For å oppfylle kravet til formbestandighet er det under broen i fatområdet for spunsene et fritt rom eller en gjennombrytning av ribbeveggene. Denne forholdsregel er særlig viktig på grunn av den herved oppnådde gunstige spenningsfordeling innenfor selve spunsen under krympningsforløpet. With this precaution, the rib bridges absorb the oppositely acting shrinkage stresses and force the sheet piles into a parallel, symmetrical position about the barrel's axis so that the sheet pile opening planes align with the stacking plane in the top surface of the barrel. As a stacked barrel must have the largest possible stacking surface available, the edges of the sheet piles lying in recesses form part of the stacking surface. Skewed positioning of the sheet piles would cause unevenness in the stacking surface and thereby prevent a tipping-safe stacking position. This risk is excluded with the new precaution. In order to meet the requirement for dimensional stability, there is a free space or a breakthrough in the rib walls under the bridge in the barrel area for the sheet piles. This precaution is particularly important because of the favorable stress distribution achieved in this way within the sheet pile itself during the shrinkage process.
I en fordelaktig utførelsesform av oppfinnelsen er det frie spunsområde som ligger lavere enn ribbebroen, innsnevret til dannelse av en i fortsettelse av spunsens indre gjengeparti liggende konisk anleggsflate for den i spunstappen fastholdte pakning og en på-følgende sylindrisk anleggsflate for den fra spunstappens bunn utragende mansjett. In an advantageous embodiment of the invention, the free sheeting area that is lower than the rib bridge is narrowed to form a conical contact surface for the gasket held in the sheet pile and a subsequent cylindrical contact surface for the cuff projecting from the bottom of the sheet pile, which is in continuation of the internal threaded part of the sheet pile .
Ved denne utførelsesform oppnås en størst mulig formbestar1 dighet ved at det nedre spunsparti som medvirker i tetningsfunksjonen, trekkes lengst mulig vekk fra ribbebroen for å oppnå et likt spennings-forløp under krympeforløpet ved avkjøling av fatet i blåseformen. Den koniske innsnevring i det nedre spunsparti avviser kontinuerlig spen-ningsspisser. In this embodiment, the greatest possible dimensional stability is achieved by the lower sheet part, which contributes to the sealing function, being pulled as far as possible away from the rib bridge in order to achieve an equal stress progression during the shrinkage progression when cooling the barrel in the blow mould. The conical narrowing in the lower part of the sheet pile continuously repels stress spikes.
Herved blir alle spunssoner som skal opprettholdes med særlig nøyaktig pasning, nemlig de i tetningen deltagende deler, be-liggende i det område hvor det overalt hersker jevnt spenningsforløp under krympningen og dermed størst formbestandighet. De tolerante en-dringer som bevirkes av ribbebroens overgang i den ikke-kritiske spuns-sone, opptas uten videre i det indre gjengeparti som ikke umiddelbart deltar i tetningen. In this way, all batten zones that must be maintained with a particularly precise fit, namely the parts participating in the seal, are located in the area where there is everywhere an even stress course during the shrinkage and thus the greatest shape retention. The tolerant changes caused by the transition of the rib bridge in the non-critical sheet pile zone are taken up without further ado in the internal threaded part which does not immediately participate in the seal.
Oppfinnelsen skal forklares nærmere i det følgende under henvisning til tegningen hvor The invention shall be explained in more detail in the following with reference to the drawing where
fig.l viser et sideriss av en utførelsesform av et fat ifølge oppfinnelsen, fig.l shows a side view of an embodiment of a barrel according to the invention,
fig.2 viser en øverste endebunn av det i fig.l viste fat, sett ovenfra, og fig.2 shows an upper end bottom of the barrel shown in fig.1, seen from above, and
fig.3 viser i større målestokk et snitt gjennom en spuns. fig.3 shows on a larger scale a section through a sheet pile.
I den viste utførelsesform er det tale om et fat 1 med et i fatets<5>Vcoppflate anbrakt kranøye eller løftehull 2. I fordypninger 3 i stableflaten 4 er det anbrakt spunser 5 og 6 som med sin åp-ningsplan når opp i planet for stableflaten 4. Spunsene 5 og 6 er gjennom ribbebroer 7 forbundet med fatets toppflate. In the embodiment shown, it is a barrel 1 with a tap eye or lifting hole 2 located in the top surface of the barrel. Indentations 3 in the stacking surface 4 are placed rams 5 and 6, which with their opening plane reach up to the plane of the stacking surface 4. The sponges 5 and 6 are connected to the top surface of the barrel through rib bridges 7.
Som det best fremgår av fig.3 er kun den øverste spuns-sone forbundet med ribbebroen ?. Det i tetningsfunksjonen umiddelbart deltagende spunsområde er fritt. Under spunsens indre gjengeparti 8 As can best be seen from fig.3, only the upper sheet piling zone is connected to the rib bridge ?. The sheeting area immediately participating in the sealing function is free. Under the inner threaded part of the screed 8
er det en innad fremspringende konisk tetningsflate 11 mot hvilken den i en spunstapp 10 fastholdte pakning 9 ligger fast an. Til den koniske tetningsflate 11 slutter det seg en sylindrisk anleggsflate 12 for en fra spunstappens bunn utragende tetningsmansjett 13. there is an inwardly projecting conical sealing surface 11 against which the gasket 9 held in a spigot 10 rests firmly against. The conical sealing surface 11 is joined by a cylindrical contact surface 12 for a sealing sleeve 13 projecting from the bottom of the sheet pile.
Ved hjelp av anleggsflaten 12 og mansjetten 13 tilveie-bringes det i praksis en fremre tetning til avlastning av hovedpak-ningen 9- Det ved manipulering av fatet fremkalte deformasjonstrykk oppfanges allerede av den fremre tetning. With the aid of the contact surface 12 and the sleeve 13, a front seal is provided in practice to relieve the main packing 9- The deformation pressure caused by manipulation of the barrel is already absorbed by the front seal.
Spunsen 5 er sikret med en forseglingshette 14. Det sam-me gjelder for spunsen 6. The screed 5 is secured with a sealing cap 14. The same applies to the screed 6.
Gjennom den under ribben 7 liggende utsparing ved spunsen 5 kan det stikkes en ytterligere spunssikring. A further sheet pile protection can be inserted through the recess under the rib 7 at the sheet pile 5.
