Description

Przedmiotem wynalazku jest sposób szczelnego laczenia dwóch elementów ze sztucznego tworzywa piankowego oraz urzadzenie do jego stosowania.Znany sposób zgrzewania dwóch elementów ze sztucznego tworzywa piankowego opisany zostal w patencie RFN nr 2 105 966.W isposolbie tym podgrzewa sie dwa elementy wzdluz powierzchni przeznaczonych do laczenia az do momentu istopdenia z góry okreslonej ilosci ma¬ terialu a nastepnie nadtopione elementy doprowa¬ dza sie do styku korzystanie dociskajac je do isiebie.Sposób ten ma wiele zalet ale ma tez wady.W rze¬ czywistosci, gdy sposób ten zastosuje sie do wy¬ twarzania opakowan, wówczas polaczenie dwóch elementów wystaje do wnetrza opakowania, z któ¬ rego to powodu polimery zwolnione w czasie to¬ pienia moga zbierac isie w opakowaniu powyzej znajdujacego sie w nim produkitu, powodujac po¬ gorszenie smaku d/Uiufb zapachu produkitu, zwlasz¬ cza jezeli produkt stanowi mleko lub majka. Po¬ nadto do realizacji tego sposobu zgrzewania wy¬ magane isa urzadzenia skomplikowane i dokladnie dzialajace a wytwarzanie oraz konserwacja takich urzadzen sa kosztowne.Celem wynalazku jest opracowanie sposoibu la¬ czenia dwóch elementów ze sztucznego tworzywa piankowego, który w zastosowaniu do wytwarzania opakowan nie powoduje .ryzyka, ze ciekly material dostanie se do srodka opakowania.Dalszym celem wynalazku jest skonstruowanie urzadzenia do laczenia elementów ze sztucznego tworzywa, które jest proste w budowie i nie ma wad i niedogodnosci znanych urzadzen.Wedlug wynalazku sposób szczelnego laczenia dwóch elementów ze sztucznego tworzywa pianko¬ wego polega na tym, ze podgrzewa sie czesc pierw¬ szego elementu korzystnie za pomoca podgrzewa¬ jacych szczek toptiac ja a drugi element utrzymuje sie w zasadniczo niskiej temperaturze, korzystnie temperaturze pokojowej lub otoczenia, przez co powierzchniowy material drugiego elementu w miejscu styku ze stopiona czescia pierwszego ele¬ mentu ulega gwaltownemu stopieniu, przy czynu drugi element sluzy do odprowadzania ciepla po¬ wodujac szybkie utwardzenie stopionych czesci olbu elementów.Urzadzenie do stosowania sposobu wedlug wyna¬ lazku zawiera jeden uchwyt dla kazdego elementu przeznaczonego do laczenia, podgrzewajace szczeki ruchome pomiedzy polozeniem ispoczynkowym i po¬ lozeniem, w którym stykaja sie one z pierwszym elementem dla stopienia jego czesci, podczas gdy drugi element utrzymywany jest z dala od szczek i w zasadniczo nizszej temperaturze, korzystnie temperaturze pokojowej luib otoczenia a uchwyty sa ruchome wzgledem siebie umozliwiajac szybkie zetkniecie obu elementów po uprzednim stopieniu czesci pierwszego elementu. 9123491234 3 4 lr^zedimiot wynalazku zostal uwidoczniony w przykladzie wykonania ma rysunku, na którym fig. 1—3 przedstawiaja czesc urzadzenia do laczenia dwóch elementów ze sztucznych tworzyw pianko¬ wych w pionowym przekroju i w trzech .róznych operacyjnych polozeniach.Na rysunku pokazano tyilko czesc urzadzenia do stosowania sposobu wedlug wynalazku, gdyz inne elementy urzadzenia moga byc skonstruowane w dowolny znany sposób i dlatego zastaly omi¬ niete na rysunku, zeby niepotrzebnie nie kompli¬ kowac opisu.Pokazane na rysunku urzadzenie zawiera forme 11, która jest ruchomo przymocowana do pionowo ruchomego posuwisto-zwrotnie maszynowego ele¬ mentu 10. Forme 11, w której utrzymywany jest element 38 ze sztucznego tworzywa piankowego przygotowany do polaczenia z drugim elementim 40 ze sztucznego tworzywa piankowego utrzymywa¬ nego w niepokazanyim uchwycie, stanowi odwróco¬ ny kielich 12, który w poziomym przekroju ma ksztalt prostokatny i który wokól krawedzi okres- lagacej otwór kielicha 12 ma wystep 14 zawierajacy pierscieniowe wybranie 15 skierowane do wewnatrz w kierunku dna kielicha. W wystepie 14 znajduje sie kanal 16 dla czynnika chlodzacego, który usy¬ tuowany jest wokól otworu kielicha 12.Srodkowy trzpien 13 wystaje do góry z górnej strony kielicha 12. Trzpien 13 ma w przekroju ksztalt kolowy i ma srodkowy przelotowy kanal 41, który przebiega takze przez dno kielicha 12.W pewnej odleglosci od kielicha 12 trzpien 13 ma pierscieniowy wystep 17, który zaopatrzony jest w pierscieniowy rowek, w którym z kolei umiesz¬ czone jest szczeliwo 18, którego zadanie opisane jest ponizej. Trzepien 13 majacy pierscieniowy wystep 17 jest (ruchomy w otworze 19 umieszczonym w ma¬ szynowym elemencie 10, przy czym otwór ten ma taka sama srednice co wystep 17 trzpienia 13 ale zwezony jest od dolu tak, ze utworzony jest wystep 42, o który opiera sie pierscieniowy Wystep 17 ogra¬ niczajacy ruch do dolu. kielicha 12 wzgledem ma¬ szynowego elementu 10.Maszynowy element 10 ma na swej do dolu skie¬ rowanej powierzchni wokól otworu 19 skierowany do dolu kolnierz 43, który ogranicza ruch do góry kielicha 12. Otwór 19 w górnej czesci ograniczony jest zapomoca korka 20, który wsuniety jest w otwór 19 i ma srodkowy otwór, w który wsta¬ wiona jest ,ta czesc trzpienia 13, która wystaje do góry z wystepu 17. Ta do góry wystajaca czesc trapienia 13 ma gwintowana górna koncówke 21, na której nakrecone sa nakretki 22 stykajace sie z gór¬ na powierzchnia korka 20. Od góry do korka 20 przymocowane jest gniazdo 23 zawierajace gwinto¬ wany otwór 24.Gwintowany otwór 24 laczy sie z powierzchnia pomiedzy korkiem 20 oraz górna powierzchnia pierscieniowego wystepu 17 trzpienia 13 w otworze 19 poprzez kanal 25 w korku 20. Taprzestrzen moze byc polaczona ze zródlem sprezonego powietrza po¬ przez gniazdo 23, gwintowany otwór 24 i kanal 25.Dla uszczelnienia przestrzeni pomiedzy korkiem 20 oraz pierscieniowym wystepem 17 uszczelki 26, 27, np. pierscienie w ksztalcie litery „0", wstawione sa wokól tej czesci korka 20, która wsunieta jest w otwór 19 i wokól srodkowego otworu w korku 20, przez który przechodzi trzpien 13. Tak wiec forma II z kielichem 12 i trzpieniem 13 ma mozliwosc ru¬ chu pomiedzy dolnym polozeniem pokazanym na fig. 1, w którym dolna powierzchnia pierscieniowego wystepu styka sie z wystepem 42 i górnym poloze¬ niem, w którym skierowana do góry .powierzchnia kielicha 12 styka sie ze skierowana do dolu po¬ wierzchnia kolnierza 43.W kielichu 12 ssaca plytka 28 przymocowana jest do trzpienia 44, który przechodziprz^z srodkowy otwór 41 w trzpieniu 13 * do góry poprzez korek . Otwór 41 ma przewezenie w pewnej odleglosci od jego dolnego zakonczenia a dociskowa sprezyna 31 zamontowana jest pomiedzy tym przewezeniem oraz górna powierzchnia ssacej plytki 28. Trzpien 44 zaopatrzony jest w gwintowana koncówke 32, na której nakrecone sa dwie nakretki 33 wspóldziala¬ jace z górna koncówka trzpienia 13. ^Nalezy zdawac sobie sprawe z faktu, ze istnieje mozliwosc usta¬ lania wysokosci ssacej plytki 28 w kielichu 12 za pomoca nakretek 33.Ssaca plytka 28 ma srodkowy kanal 29, który w dolnej jej czesci rozciaga sie na duza ilosc ka¬ nalów iuib otworów 30, które sa otwarte od strony dolnej powierzchni ssacej plytki 28. Zasysanie po¬ woduje sie przez to, ze kanal 29 polaczony jest ze zródlem podcisnienia za pomoca górnej gwintowa¬ nej koncówki 45 trzpienia 44. Ssaca plytka 28 mo¬ ze poruszac isie od dolnego polozenia na poziomie lub ponizej poziomu dolnej krawedzi kielicha 12 do górnego polozenia, w którym górna powierzchnia plytki styka sie z dolna powierzchnia kielicha 12.Przesuw ssacej plytki odbywa sie przy reakciji 'spre¬ zyny 31.Wokól wewnetrznego obrzeza kielicha 12 zamon¬ towany jest zaciskajacy zespól 34, który zawiera wiele ksztaltownych elementów, z których kazdy ma skierowane do dolu ramie 35, którego czesc usytuowana jest w wybraniu 15 oraz ramie 36 skie¬ rowane do wnetrza kielicha 12. Ramie 35 poruszane jest w kierunku wnetrza kielicha 12 w ten sposób, ze ramie 36 sluzace jako uruchamiajaca dzwignia zostaje przesuniete do góry w kierunku przeciw¬ nym do kierunku dzialania sprezyny 37. Ruch do góry realizowany jest za pomoca (tylnej powierzch¬ ni ssacej plytki 28, co opisano bardziej szczególowo ponizej.Powyzej opisane urzadzenie do polaczenia dwóch elementów ze sztucznego tworzywa piankowego sto¬ suje sde w nastepujacy sposób. Elementy te na przyklad stanowia rurowy element 40 oraz plaski pokrywkowy element 38, którym ma byc umiesz¬ czony na elemencie 40 po jego wypelnieniu pro¬ duktem. Najpierw plaski pokrywkowy element 38 kladzie sie na ssacej plytce 28, co korzystnie od¬ bywa sie automatycznie. Jak wynika z rysunku, pokrywkowy element jest wiekszy od otworu w kie¬ lichu 12 i z tego powodu krawedziowa czesc pla¬ skiego pokrywkowego elementu 38 opiera sie o skierowana do dolu graniczna powierzchnie kieli¬ cha 12 w przypadku, gdy dolna powierzchnia ssa- 40 45 50 55 6091234 6 cej plytki 28 jest na poziomie tej granicznej po¬ wierzchni. Po umieszczeniu w tym polozeniu pla¬ skiego pokrywkowego elementu 38 podgrzewajace szczeki 39 zostaja przesuniete do wewnatrz wcho¬ dzac w kontakt z zewnetrzna krawedzia plaskiej pokrywki 38, przez co powoduje sie topnienie z góry okreslonej ilosci materialu pokrywkowego elemen¬ tu 38 wzdluz tej krawedzi. Rurowy element 40 jest utrzymywany ponizej kielicha 12, przy czym jego os pokrywa sie z osia ssacej plytki 28 i znajduje sie w takiej odleglosci od kielicha 12, ze nie na¬ stepuje podgrzewanie materialu -rurowego elementu 40.Tak wiec material .rurowego elementu utrzymy¬ wany jest w temperaturze otoczenia lub pokojowej.Po stopieniu wystarczajacej Mosci materialu wzdluz zewnetrznej krawedzi plaskiego pokrywkowego ele¬ mentu 38 podgrzewajace szczeki 39 zostaja odsu¬ niete i maszynowy element 10 zostaje obnizony. Pc obnizeniu maszynowego elementu 10 o pewna od¬ leglosc dolna powierzchnia plaskiego pokrywkowego elementu styka sie z wystajaca do góry czescia brzegowa rurowego elementu 40. Podczas dalszego iruchu w dól dolna graniczna powierzchnia kieli¬ cha 12 przesuwa sie w dól na górna (brzegowa czesc rurowego elementu 40 w tym samym czasie, gdy ssaca plytka 28 dociskana jest do kielicha 12 wbrew dzialaniu sprezyny 31.Czasami celowe jest lekkie przyhamowanie ru¬ chu kielicha 12 i w takim przypadku przestrzen pomiedzy pierscieniowym wystepem 17 oraz kor¬ kiem 20 wypelniona jest sprezonym powietrzem.Dzieki doprowadzeniu sprezonego powietrza, które moze byc regulowane podczas cyiMu pracy, uzysku¬ je sie dzialanie sprezyny takie, ze mozna uzyskac maksymalna sile docisku w stosunku do wytrzy¬ malosci na sciskanie sztucznego tworzywa. Gdy ssaca plytka 28 przesuwa sie do kielicha 12 wbrew dzialaniu sprezyny 31, wówczas zewnetrzna brze¬ gowa czesc plaskiego pokrywkowego elementu 38, na skutek jej docisku za pomoca dolnej granicznej powierzchni kielicha zostaje zacinana w dól i do wewnatrz w kierunku górnej brzegowej czesci ru¬ rowego elementu 40. Gdy ssaca plytka 28 przesunie sie o pewna odleglosc do kielicha 12, wówczas jej tylna powierzchnia opiera sie o uruchamiajace ra¬ miona 36 zaciskajacych ksztaltowych elementów, które przez to zostaja odchylone tak, ze ramiona przesuwaja sie do wewnatrz w kierunku wne¬ trza kielicha 12 i zaczyna stykac sia. z zewnetrzna brzegowa. ua**hf puki ywIKowego elementu 38, któ¬ ra zostaje wówczas zagieta do dolu na (rurowym elemencie 40, dociskajac zewnetrzna brzegowa czesc do jej najdalszego polozenia (pokazanego na fig. 3) na zewnetrznej powierzchni rurowego elementu 40.Wówczas stopiony material plaskiego pokrywko¬ wego elementu 38 styka sie z zimnym materialem rurowego elementu 40, tak ze najpierw powierzch¬ niowy material rurowego elementu 40, który styka sie ze stopionym (materialem plaskiego pokrywko¬ wego elementu 38, ulega gwaltownemu stopieniu a nastepnie szybkiemu utwardzeniu przez odpro¬ wadzenie ciepla z jednej strony przez rurowy ele¬ ment 40 i z drugiej strony ze wzgledu na to, ze zaciskajace ksztaltowe elementy, które sa stosun¬ kowo chlodne, w ich spoczynkowym polozeniu leza blisko kanalu 16 czynnika chlodzacego.

PLThe subject of the invention is a method of sealing two elements of foam plastic and a device for its use. A known method of welding two elements of foam plastic was described in German Patent No. 2 105 966. In this way, two elements are heated along the surfaces to be joined until until a predetermined amount of material is blown and then the molten elements are brought into contact by pressing them against each other. This method has many advantages but also has disadvantages. In fact, when this method is used in the manufacture of packaging, then the combination of two elements protrudes into the inside of the package, for which reason the polymers released during melting may collect and accumulate in the package above the product contained in it, causing the taste and odor of the product to deteriorate, especially if the product is milk or milk. In addition, complex and accurate equipment is required to carry out this welding method, and the production and maintenance of such equipment is expensive. The object of the invention is to provide a method of joining two pieces of plastic foam which, when used for the production of packaging, does not cause. The risk of liquid material getting inside the package. A further object of the invention is to construct a device for connecting plastic elements, which is simple in construction and does not have the drawbacks and inconveniences of known devices. According to the invention, a method of sealing two plastic elements - foam This is where part of the first element is heated, preferably by means of heated melting jaws, and the second element is kept at a substantially low temperature, preferably at room or ambient temperature, so that the surface material of the second element in contact with the molten part first element The device for the application of the method according to the invention comprises one handle for each element to be joined, heating the jaws movable between the rest and the rest positions. a position in which they contact the first element to fuse parts of it, while the second element is kept away from the jaws and at a substantially lower temperature, preferably room or ambient temperature, and the handles are movable in relation to each other allowing for quick contact between the two elements after melting the parts. first element. The invention is illustrated in an exemplary embodiment of the drawing, in which Figures 1-3 show a part of a device for joining two plastic foam elements in a vertical section and in three different operational positions. The figure shows only a part. devices for carrying out the method according to the invention, since the other elements of the device can be constructed in any known manner and are therefore omitted from the drawing in order not to complicate the description unnecessarily. The device shown in the drawing comprises a mold 11 which is movably attached to a vertically movable device. reciprocating machine element 10. The mold 11 in which the foam plastic element 38 is held ready to be joined to a second foam plastic element 40 held in a holder not shown is an inverted cup 12 which in a horizontal has a rectangular cross-section and has an edge around the edge defining the socket opening The icha 12 has a protrusion 14 including an annular recess 15 facing inward towards the socket bottom. In the projection 14 there is a channel 16 for the coolant which is positioned around the opening of the socket 12. The central pin 13 extends upwards from the upper side of the socket 12. The spindle 13 is circular in cross-sectional shape and has a central through channel 41, which also extends over through the bottom of the cup 12. At a distance from the cup 12, the mandrel 13 has a ring-shaped shoulder 17 which is provided with a ring groove in which, in turn, the sealant 18 is placed, the purpose of which is described below. The flap 13 having a ring-shaped projection 17 is (movable in a hole 19 in the machine element 10, the hole having the same diameter as the projection 17 of the pin 13 but tapered at the bottom so that a projection 42 is formed against which it rests. Ring-shaped protrusion 17 limiting the downward movement of socket 12 relative to machine element 10. Machine element 10 has on its downward facing surface around opening 19 a downward flange 43 which restricts upward movement of socket 12. Opening 19 the upper part is limited by a plug 20 which is inserted into the hole 19 and has a central hole in which is inserted, that part of the pin 13 which protrudes upwards from the projection 17. The upwardly projecting part of the trap 13 has a threaded upper an end 21 on which the nuts 22 are screwed in contact with the upper surface of the plug 20. A socket 23 containing a threaded hole 24 is attached from the top to the plug 20. The threaded hole 24 connects to the surface of the plug 20. From the plug 20 and the upper surface of the annular shoulder 17 of the pin 13 in the bore 19 through the channel 25 in the plug 20. The space may be connected to a source of compressed air through the seat 23, the threaded hole 24 and the channel 25. To seal the space between the plug 20 and the ring protrusion 17 of the gasket 26, 27, e.g. "0" -shaped rings, are inserted around that part of the plug 20 which is inserted into the hole 19 and around the central hole in the plug 20 through which the spindle 13 passes. Thus, Form II with the socket 12 and spindle 13 are movable between the lower position shown in FIG. 1, in which the lower surface of the annular projection contacts the projection 42 and the upper position in which the upwardly directed face of the socket 12 contacts the upwardly facing projection. the lower surface of the flange 43. In the socket 12, the suction plate 28 is attached to a pin 44 which passes from the center hole 41 in the pin 13 upwards through the plug. The hole 41 has a groove some distance from its lower end and a pressure spring 31 is mounted between this groove and the upper surface of the suction plate 28. The spindle 44 is provided with a threaded end 32 on which two nuts 33 are screwed interacting with the upper end of the spindle. 13. ^ Be aware that it is possible to determine the height of the suction plate 28 in the socket 12 by means of the nuts 33. The suction plate 28 has a central channel 29 which extends over a large number of iuib channels at the bottom. holes 30, which are open on the lower surface of the suction plate 28. The suction is achieved by connecting the channel 29 to a vacuum source by means of the upper threaded end 45 of the pin 44. The suction plate 28 can be moved away from the lower position at or below the level of the lower edge of the cup 12 to the upper position where the top surface of the plate meets the lower surface of the cup 12 The suction plate is displaced by the response of the spring 31. A clamping assembly 34 is mounted around the inner rim of the socket 12, which comprises a plurality of shaped elements, each with a downwardly directed frame 35, part of which is located in the recess 15. and the frame 36 facing towards the inside of the cup 12. The arm 35 is moved towards the inside of the cup 12 in such a way that the frame 36 serving as the actuating lever is moved upwards in a direction opposite to the operating direction of the spring 37. Upward movement is performed is by means of (the rear surface of the suction plate 28, as described in more detail below. The above-described device for joining two plastic foam elements is used as follows. These elements are, for example, a tubular element 40 and a flat cover element 38 with which it is to be placed on the element 40 after it has been filled with the product. First, the flat cover element 38 is placed on the suction plate 28, which preferably takes place automatically. As can be seen from the drawing, the cover element is larger than the opening in the cup 12, and therefore the edge portion of the flat cover element 38 abuts the downwardly facing peripheral surface of the cup 12 in the event that the lower surface of the cup is sucked. No. 55,6091234 6 of plate 28 is at the level of this boundary surface. When the flat cover element 38 is placed in this position, the heating jaws 39 are moved inwards to contact the outer edge of the flat cover 38, thereby melting a predetermined amount of cover material of the element 38 along that edge. The tubular element 40 is held below the socket 12, with its axis coinciding with the axis of the suction plate 28 and located at such a distance from the socket 12 that there is no heating of the tubular material 40 material. Thus, the material of the tubular element 40 is not heated. It is important at ambient or room temperature. After sufficient material has melted along the outer edge of the flat lid element 38, the heating jaws 39 are moved away and the machine element 10 is lowered. Pc lowering the machine element 10 by a certain distance, the lower surface of the flat cover element contacts the upwardly projecting edge portion of the tubular element 40. During the further downward movement, the lower peripheral surface of the tooth 12 moves downwards to the upper (edge portion of the tubular element). 40 at the same time as the suction plate 28 is pressed against the cup 12 against the action of the spring 31. Sometimes it is expedient to slightly inhibit the movement of the cup 12, in which case the space between the annular projection 17 and the stopper 20 is filled with compressed air. of compressed air, which can be regulated during the course of operation, the action of the spring is obtained such that a maximum contact force can be obtained in relation to the compressive strength of the plastic. When the suction plate 28 moves into the cup 12 against the action of the spring 31, then the outer edge of the lid flat member 38, due to its compression by means of the lower boundary surface of the socket it is cut downwards and inwards towards the upper edge of the tubular member 40. As the suction plate 28 moves some distance from the socket 12, its rear face rests against the actuating arms 36 clamping shaped elements which are thereby pivoted so that the arms slide inwardly towards the inside of the socket 12 and the force begins to contact. from the outer shoreline. ua ** hf knocks of the resin element 38, which is then bent downwards on the (tubular member 40, pressing the outer edge portion to its farthest position (shown in Fig. 3) on the outer surface of the tubular member 40. Of the element 38 is in contact with the cold material of the tubular element 40, so that first the surface material of the tubular element 40, which comes into contact with the melt (the material of the flat cover element 38, is rapidly melted and then rapidly hardened by the dissipation of heat). on the one hand through the tubular member 40, and on the other hand, because the clamping shaped members, which are relatively cool, in their rest position lie close to the coolant channel 16. The molten edge portion is thus brought into contact with the outer surface of the tubular element 40 and therefore the molten material cannot enter the interior in the thus performed The device shown in the drawing is adapted to close packages with a rectangular cross-section, and of course in this case there are mounted further clamping members 34, which are perpendicular to the ones shown in the drawing. Regardless of these members in the cup 12 Fixed elements forming the X5 spacers of the packaging are installed. As the flat cover member 38 and the upper edge portion of the tubular member 40 engage the socket 12, they press against the shaping members. These stationary shaping elements implement an additional flattening of the corners of the packages, which is often necessary. PL
