Description

Uppfinnare: W Goldschmidt Prioritet begiird fran den 5 april 1958 (Forbundsrepubliken Tyskland) Foreliggande uppfinning hanfor sig till apparater far insprutning av saltlake av sidant slag dar saltlake under tryck insprutas i ett k6ttstycke medelst en injektionsnal Over en rorlig vagg i form av ett gummimembran under paverkan av ett tryckmedium sasom exempelvis tryckvatten eller tryckluft. Inventor: W Goldschmidt Priority claimed from 5 April 1958 (Federal Republic of Germany) The present invention relates to apparatus for injecting brine of the side type in which brine is injected under pressure into a piece of meat by means of an injection needle over a movable rock in the form of a rubber membrane under of a pressure medium such as compressed water or compressed air.

Dylika insprutningsapparater aro redan kanda. Dessa apparater aro emellertid behallade med vissa olagenheter. BI. a. maste sedan. lakebehallaren tomts, ett lock oppnas for att ny saltlake skall kunna pfyllas. Delta sker for hand, vilket medfor att laken utsattes f5r risken att bliva fororenad och är denna pafyllning dessutom ratt sa tidsodande. Mojlighet att filtrera saltlaken foreligger icke. liven automatiskt pafyllbara insprutningsapparater aro kanda. Vid dessa apparater maste vid pafyllning av saltlake och apparatens omstallning till insprutning en install-fling av en nedtill anordnad trevagskran ske for hand eller med hjalp av en pedal. Denna pifyllning är rutt tidsOdande da den nya la-ken tillf8res enbart under atmosfarens tryck. Lakenivan i fOrradsbehallaren maste harvid alltid vara hogre an apparatens ldge, vilket är olampligt saval av utrymmes- som av tekniska skal. Such injectors are already known. However, these devices are fraught with certain ills. BI. a. must then. the lake container is empty, a lid is opened so that new brine can be filled. Delta takes place by hand, which means that the lake is exposed to the risk of becoming contaminated and this filling is also just as time-consuming. It is not possible to filter the brine. life automatic refillable injectors aro kanda. In the case of these devices, when filling brine and converting the device to injection, an installation of a three-car crane arranged at the bottom must be done by hand or with the aid of a pedal. This pipe filling is time consuming as the new lake is supplied only under atmospheric pressure. The sheet level in the storage container must always be higher than the height of the appliance, which is unsuitable for both space and technical shells.

Vidare besta dessa apparater av emaljerat gjutjarn eller annat icke korrosionsmotstandligt material. Emaljen skadas latt av stOtar och angripes sa smaningom av saltlaken. Den harvid uppkomna rostbelaggningen fororenar saltlaken, vilken kan medfora, att den vara, i vilken insprutningen dger rum, skadas av flackar och harigenom minskar i varde. Furthermore, these devices consist of enamelled cast iron or other non-corrosion-resistant material. The enamel is easily damaged by bumps and is gradually attacked by the brine. The resulting rust coating contaminates the brine, which can lead to the product in which the injection takes place being damaged by flakes and thereby decreasing in value.

Foreliggande uppfinning har till andamal att astadkomma en hygienisk och sakert arbetande apparat, vars saltlakebehallare efter uttomning snabbt kan aterpafyllas utan omstandliga och tidsodande manuella operationer. The present invention has for its object to provide a hygienic and safe working apparatus, the brine container after emptying can be quickly refilled without cumbersome and time-consuming manual operations.

Enligt uppfinningen uppnas detta genom att en insprutningsapparat, med ett pa salt-, laken via ett bojligt gummimembran verkande tryckmedium, forses med anordningar, vilka, dá tryekmedelstillforseln frigores, utpressar tryckmediet med sadan kraft, att ett vacuum uppstar i saltlakebehallaren, -varvid ny salt-lake snabbt och automatiskt palylles genom det harav uppkomna suget. Utaver den snabba pafyllningen ernas aven, nit apparaten ãr helt oberoende av det atmosfariska trycket och saledes kan placeras hOgre an vatskenivan i forradsbehallaren. According to the invention, this is achieved in that an injection apparatus, with a pressure medium acting on the salt sheet via a flexible rubber membrane, is provided with devices which, when the pressure medium supply is released, squeeze out the pressure medium with such force that a vacuum arises in the brine container. -lake is quickly and automatically palylled by the resulting suction. In addition to the rapid filling, the appliance is completely independent of the atmospheric pressure and can thus be placed higher than the water level in the storage tank.

Sadana anordningar kunna best& av gummi- eller fjaderanordningar, som stâ i forbindelse med det bojliga membranet eller av pa membranet ovanifran verkande fjadertryck. Such devices may consist of rubber or spring devices which are connected to the flexible membrane or to spring pressure acting on the membrane from above.

Enligt uppfinningen bestar anordningen fOr tryckmediets utpressande av en elastisk gummihalkropp, vilken sammandrar sig sedan tryckmedelstillforseln frigivits. According to the invention, the device for squeezing the pressure medium consists of an elastic rubber hollow body, which contracts after the supply of pressure medium has been released.

Omkopplingen for tryckmediets in- eller utsldppande sker enligt uppfinningen medelst en pedalanordning, bestaende av en tatande bottenplatta, som är f6rsedd med en urborrning och ett anslutningsror Mr gummihalkroppen samt av en kring en skaftskruv svangbar pedal, som tatande anligger mot bottenplattan genom en hylsa och en metallskiva genom paverkan av det tryck som utOvas av tryclunediet. Denna anordning medfor ett snabbt och bekvamt betjanande av apparaten. 2 Tatningen blir med tiden alit effektivare genom metallskivan.s inslipande under fortsatt anvandning. According to the invention, the switching for the inlet or discharge of the pressure medium takes place by means of a pedal device, consisting of a mounting bottom plate, which is provided with a bore and a connecting tube. metal plate by the influence of the pressure exerted by the pressure nozzle. This device results in a quick and convenient operation of the apparatus. 2 The seal becomes over time more efficient through the grinding of the metal plate during continued use.

Enligt uppfinningen-är saval saltlakebehallaren som tryckmedelsbehallaren forsedd mecl utatriktade fldnsar for uppbarande av tva flansringar, mellan vilka det bojliga gummimembranet fasthalles med hj alp av fastskruvar. According to the invention, both the brine container and the pressure medium container are provided with outwardly directed fluids for supporting two flange rings, between which the flexible rubber membrane is secured by means of screw screws.

Ldmpligen utfores apparaten av korrosionsbestandigt ddelstal eller konstmaterial, sa att alla risker for korrosion nedbringas till ett minimum. The apparatus is generally made of corrosion-resistant parts or artificial material, so that all risks of corrosion are reduced to a minimum.

En saltlakesprutapparat enligt uppfinningen askadliggores pa bifogade ritningar dar fig. 1 visar apparaten i skarning och fig. 2 manoverpedalen sedd Iran sidan och — delvis i skarning — ovanifran. A brine spraying apparatus according to the invention is shown in the accompanying drawings where Fig. 1 shows the apparatus in cut and Fig. 2 the control pedal seen from the Iran side and - partly in cut - from above.

Mellan en overdel 1 och en underdel 2 av rostfritt ddelstal är insatt ett bojligt gummimembran 3. Delarna 1 och 2 fasthallas mot varandra genom 15sa. flanSringar 4, 5 och fastskruvar 6. Between an upper part 1 and a lower part 2 of stainless steel part is inserted a flexible rubber membrane 3. The parts 1 and 2 are held against each other by 15sa. flanges 4, 5 and screws 6.

- Vid underdelen 2 är en manoverpedal an, ordnad, rned vilken tryckmediets tillforsel och avledande regleras. Vid derma manOverpedal är,. pa ett anslutningsrOr 16, anordnad en elastisk gummihalkropp 8, vilken har till app-gift att astadkomma en snabb utpressning av tryckmediet som instrOmmat i densamma. Genom det harav i saltlakebehallaren 1 uppkomna, vacuumet uppstar ett starkt sug, som a sin sida medfor en mycket snabb pafyllning av saltlake. At the lower part 2 a control pedal is arranged, under which the supply and deflection of the pressure medium are regulated. At this manOverpedal is ,. on a connecting tube 16, arranged an elastic rubber hollow body 8, which has the effect of causing a rapid squeezing out of the pressure medium which has flowed into it. Due to what has arisen in the brine container 1, the vacuum creates a strong suction, which in turn results in a very fast filling of brine.

Insugning och utsprutning av saltlake ur lakebehallaren sker genom en grenkoppling 9, som är fOrsedd med en backventil 10. Grenriirets diameter dr sa. stor, att tillstromning av lake och behallarens nypafyllning kan agar nun pa nagra sekunder. Laken filtreras härvid innan den instrommar i apparaten, varvid fororeningar avldgsnas. Suction and spraying of brine from the lake container takes place through a branch coupling 9, which is provided with a non-return valve 10. The diameter of the branch pipe dr sa. large, that the inflow of lake and the container's pinch filling can now agar in a few seconds. The lake is then filtered before it flows into the apparatus, whereby contaminants are removed.

- Den i fig. 2 visade manoverpedalen bestar av en stationar tatande bottenplatta 7 med en urborrning 13 for tryckmediets till- och utlopp och en kring en skaftskruv 12 svanghart lagrad pedal 11, som likaledes är fiirsedd med en urborrning. The control pedal shown in Fig. 2 consists of a stationary bottom plate 7 with a bore 13 for the inlet and outlet of the pressure medium and a pedal 11 which is pivotally mounted around a shaft screw 12, which is likewise provided with a bore.

Pedalen 11 kan svangas sa att dess urborrning kommet i linje med urborrningen 13 i den stationdra bottenplattan, sá som visas a ritningen, och bereder harigenom mOjlighet for tryckmediet att stromma in i den elastiska gummihalkroppen 8 da. pedalen 11 samtidigt är forbunden med tryckkallan genom en slang. The pedal 11 can be pivoted so that its bore is aligned with the bore 13 in the stationary base plate, as shown in the drawing, and thereby provides an opportunity for the pressure medium to flow into the elastic rubber hollow body 8 da. the pedal 11 is simultaneously connected to the pressure source through a hose.

Nd.r pedalen 11 befinner sig i sitt andra Idge utmynnar dess urborrning mot den stationdra tatande bottenplattan 7, varigenom ytterligare tillfOrsel av tryckmediet till gummihal kroppen 8 forhindras samtidigt som urborr: ningen 13 i bottenplattan 7 medgiver .avledande av forhrukat tryckmedium. When the pedal 11 is in its second Idge, its bore opens towards the stationary bottom plate 7, whereby further supply of the pressure medium to the rubber hollow body 8 is prevented at the same time as the bore 13 in the bottom plate 7 allows diverting of pre-crushed pressure medium.

Tatning mellan den stationdra. bottenplattan 7 och pedalen 11,. sker ddrigenom, att tryckmediet pressar en manscliett eller hylsa 14 pa en metallskiva 15 mot bottenplattan. Seal between the station pull. the bottom plate 7 and the pedal 11 ,. This is done by the pressure medium pressing a male chip or sleeve 14 on a metal plate 15 against the bottom plate.

Apparaten verkar pa foljande satt: Pedalen 11 Star medelst en slang i forbin- delse med tryckkallan. Yid detritningen visade laget. av. pedalen .strommar tryckmediet genom anslutningsroret 16 in i den elastiska halkroppen 8, varvid denna utvidgas. Hdrigenom utsattes det bedliga membranet 3 for ett kraftigt tryck, vilket medfor att den i lakebehallaren befintliga saltlaken dvenledes sattes under tryck. Genom det harvid uppkomna trycket tillslutes tilloppsledningen med anslutningsdelen 18 hermetiskt av backventilens 10 kula. Saltlaken avlagsnas ur lakebehallaren 1 genom grenkopplingen 9 och dess anslutningsdel 17 genom en slang varefter den insprutas i kottvaran genom en sprutpistol eller injektionsnal. The device operates in the following way: Pedal 11 Stares by means of a hose in connection with the pressure source. Yid the drawing showed the team. of. the pedal flows the pressure medium through the connecting tube 16 into the elastic sliding body 8, whereby it expands. As a result, the bevelable membrane 3 is subjected to a strong pressure, which means that the brine present in the brine container is also put under pressure. Due to the pressure thus generated, the supply line with the connecting part 18 is hermetically closed by the ball of the non-return valve 10. The brine is removed from the brine container 1 through the branch coupling 9 and its connecting part 17 through a hose, after which it is injected into the coniferous product through a spray gun or injection needle.

När laken uttomts och utsprutats frigores anslutningsrorets 16 kanal 13 for uttomning. av tryckmediet genom en tryckning pa pedalear 11. I sin stravan att sammandraga sig till sin ursprungliga form utpressar gummihalkroppen 8 det forbrukade tryckmediet snabbt och kraftigt. I lakebehallaren 1 bildas samtidigt, genom att membranet 3 drages neat, ett vacuum, varvid backventilens kula 10 i grenkopplingen 9 losgores fran utsugningsledningen genom det uppkomna suget och fly lake instrommar- snabbt i apparaten frau en fOrradsbehallare, Pedalen 11 aterfores genom en fottryckning ph en icke visad aterforingshavarm eller genom en fjader, I sistnamnda fall maste fottrycket vidmakthallas under hela pafyllningsproceduren. When the sheet is emptied and sprayed out, the channel 13 of the connecting pipe 16 is released for emptying. of the pressure medium by pressing on pedals 11. In its struggle to contract to its original shape, the rubber hollow body 8 squeezes out the consumed pressure medium quickly and vigorously. In the lake tank 1 a vacuum is formed at the same time, by pulling the diaphragm 3, a vacuum, whereby the ball valve 10 in the branch coupling 9 is released from the suction line through the suction generated and the lake flows in quickly into the apparatus from a storage tank. not shown return arm or through a spring, In the latter case the foot pressure must be maintained throughout the filling procedure.

Apparatens anvandning är joke begrdnsad till enbart insprutande av saltlake i ett Wittstycke utan kan densa.mina komma till anvandning vid manga andrd tillfallen cla en behallare skall tommas under tryck och darefter - snabbt aterfyllas. The use of the appliance is joke limited to only injecting brine into a Witt piece but can be used in many other cases cla a container must be emptied under pressure and then - quickly refilled.
