Opfindelsen angår en mekanisme til tømning af beholdere, f.eks. affaldsbeholdere, hvilken mekanisme er af den nærmere i krav 11 s indledning angivne art.The invention relates to a mechanism for emptying containers, e.g. waste containers, which mechanism is of the kind specified in the preamble of claim 11.

Fra US-patentskrift nr. 2.951.602 kendes en tømningsmekanisme, 5 hvori en støtte- og låsestang strækker sig på tværs mellem de to løftesvingarme, medens beholderen til optagelse af denne har et optageorgan i form af et par øreformede flige, som hver udgør en optagedel. I en forud bestemt vinkelstilling af løftesvingarmparret løber disse flige, på grund af at bæreor-10 ganerne på beholderen er anbragt oven for dennes tyngdepunkt, over støtte- og låsestangen og optager denne i optagedelene.US Patent No. 2,951,602 discloses an emptying mechanism 5 in which a support and locking rod extends transversely between the two lifting swing arms, while the receptacle for receiving it has a receiving means in the form of a pair of ear-shaped tabs, each of which forms a receiving part. In a predetermined angular position of the lever swing pair, these tabs run over the support and locking rod and receive it in the receiving portions, due to the carrier means placed above its center of gravity.

Ved yderligere opadsvingning af løftesvingarmparret er enhver relativ vippebevægelse af beholderen i forhold til løftesvingarmparret forhindret. Dersom man ønsker, at beholderen .Upon further upward swing of the lift swing arm pair, any relative tilting movement of the container relative to the lift swing arm pair is prevented. If you want the container.

15 skal kunne vippes gennem en forholdsvis stor vinkel, er det nødvendigt at udforme løftesvingarmparret til et hertil svarende stort svingområde. Med henblik herpå er den således kendte mekanisme udstyret med et mellemled i løftesvingarmene og med en yderligere hydraulisk arbejdscylinder til at 20 svinge armene i disse led i forhold til hinanden. Dette nødvendiggør imidlertid en væsentligt forøget maskinel indsats og dermed en væsentlig forhøjelse af mekanismens pris. Desuden samvirker den på beholderen anbragte optagedel med låseorganet i princippet kun i en del af en svingebevægelse af 25 beholderen i forhold til svingarmparret. Beholderen, som med sine på siden anbragte bæretappe er optaget i griberne, vil derfor i den nederste del af løftebevægelsen blive båret praktisk taget frit pendlende og er ikke på nogen måde ført eller sikret. Dersom beholderen belastes uensartet, vil der ved 30 løftning af beholderen opstå en betydelig pendulbevægelse, som i praksis kan føre til, at beholderens bæretappe ved løftebevægelsens begyndelse glider fremad ud af griberne. Denne risiko for, at beholderen glider ud under tømningsforløbet, f.eks. ved rystning fra griberområdet, udgør en betydelig 35 fare for betjeningspersonalet.15 to be able to be tilted through a relatively large angle, it is necessary to design the lift swing arm pair to a correspondingly large swing area. To this end, the mechanism thus known is provided with an intermediate link in the lift swing arms and with an additional hydraulic working cylinder for swinging the arms in these links relative to each other. However, this necessitates a significantly increased machine effort and thus a significant increase in the price of the mechanism. In addition, the receptacle portion disposed on the container cooperates with the locking means in principle only in a portion of a swinging movement of the container relative to the swing arm pair. The container, which, with its lateral support pins, is accommodated in the grippers, will therefore be carried in the lower part of the lifting motion practically freely commuting and is in no way guided or secured. If the container is unevenly loaded, a substantial pendulum movement will occur upon lifting the container, which in practice can cause the container carrier pin to slide forward out of the grippers at the beginning of the lifting movement. This risk of the container slipping during the emptying process, e.g. when shaken from the gripper area, there is a considerable danger to the operator.

Fra DE-AS nr. 1.218.935 kendes en tømningsmekanisme, der omfatter en på beholderen anbragt optageindretning i form af to stort set 0- eller I-formede fanggafler, hvoraf den første begrænser den relative bevægelse af affaldsbeholderen i 5 forhold til svingarmene i vandret retning, og den anden i samvirke med den første begrænser bevægelsen i lodret retning, medens bæretappene er anbragt på svingarmenes ender. I den således kendte tømningsmekanisme udfører beholderen ved tømningen en tvangsmæssig svingebevægelse, idet beholderens 10 svingelighed i forhold til svingarmene, især også i svinge-bevægelsens øvre område, er forholdsvis stærkt begrænset. Beholderen kan således slet ikke svinge frit i forhold til svingarmene. Under afslutningen af svingebevægelsen kan bæretappene let glide ud af optageindretningerne, dersom vægtom-15 lejringen i tømningsforløbets slutfase sker pludseligt fra den øvre til den nedre flange.DE-AS No. 1,218,935 discloses a discharge mechanism comprising a receiving device arranged on the container in the form of two largely 0 or I-shaped catch forks, the first of which limits the relative movement of the waste container in relation to the swing arms in the horizontal. direction, and the second, in conjunction with the first, restricts movement in the vertical direction while the support pins are disposed on the ends of the swing arms. In the emptying mechanism thus known, the container performs a forced pivotal movement during emptying, with the pivotality of the container 10 relative to the pivot arms, especially also in the upper region of the pivotal motion, being relatively severely limited. Thus, the container cannot swing freely at all relative to the swing arms. At the end of the pivotal movement, the support pins can easily slide out of the pick-up devices if the weight change in the final phase of the emptying process occurs suddenly from the upper to the lower flange.

Der kendes også, jfr. DE-OS nr. 1.937.398, mekanismer, hvori de på beholderen og på svingarmparret fordelte støtte- og låseorganer og optageindretninger på grund af beholdertyngde-20 punktets beliggenhed i forhold til bæretappene ligger over for hinanden under svingarmparrets opadgående svingebevægelse. Med sådanne mekanismer kan den beholder, der skal tømmes, praktisk taget kun svinges opad til en stilling, hvor dens åbningsplan står lodret.It is also known, cf. DE-OS No. 1,937,398, mechanisms in which the support and locking means and the locking means and receiving devices distributed on the container and on the swingarm pair due to the position of the container center of gravity relative to the supporting pins lie opposite each other during the upward swinging movement of the swingarm pair. With such mechanisms, the container to be emptied can practically only be swung upwards to a position where its opening plane is vertical.

25 På denne baggrund er det opfindelsens formål at anvise udformningen af en mekanisme af den indledningsvis nævnte art, hvormed det er muligt at sikre, at bæreorganerne på den beholder, der skal tømmes, og som under løftningen med sine bæreorganer hænger pendlende i svingarmenes gribere, ikke kan falde ud af 30 griberne, uden at muligheden for relativ svingebevægelse af beholderen i den ene og anden retning i forhold til svingarmene, især også i disses øvre svingebevægelse-område, er udelukket.Accordingly, it is the object of the invention to provide the design of a mechanism of the kind mentioned above, by which it is possible to ensure that the supporting members of the container to be emptied and which during lifting with its supporting members are suspended in the swing arms of the swing arms, can not fall out of the 30 grippers without the possibility of relative pivotal movement of the container in one direction relative to the pivot arms, especially also in their upper pivotal area, is excluded.

Det angivne formål opnås ved en mekanisme, som ifølge opfindelsen er ejendommelig ved den i krav l's kendetegnede del angivne udformning og indretning.The stated object is achieved by a mechanism which according to the invention is characterized by the design and arrangement as defined in claim 1.

Herved opnås, at den beholder, der skal tømmes, får lejlighed 5 til at udføre en svinge- eller vippebevægelse i både den ene og den anden retning i forhold til løftesvingarmparret. Beholderens svingebevægelse i den ene retning i forhold til løftesvingarmene svarer i hovedsagen til den i de kendte mekanismer tilvejebragte relative svingebevægelse mellem beholderen 10 og løftesvingarmene indtil det punkt, hvor i de kendte mekanismer støtte- og låsemekanismens dele føres sammen. Ved mekanismen ifølge opfindelsen er beholderen imidlertid allerede under denne første relative svingebevægelse sikret mod at falde ud af løftesvingarmene, ved at støtteorganet går ind i det ene 15 optageorgan. Ud over den relative svingebevægelse i den første retning kan beholderen også vippe i den modsatte retning i forhold til løftesvingarmene, herved opnås, at beholderen, når løftesvingarmene befinder sig i det øverste område af deres svingebevægelse, ved udnyttelse af denne mulighed for 20 den relative svingebevægelige i den anden retning, endnu kan vippes langt forbi den vinkel, der svarer til løftesvingarmenes svingeområde, så at tømningen forbedres. Under denne anden relative svingebevægelse bevæger støtteorganet sig ind i optageorganets anden optagedel, så at beholderen også under denne 25 anden relative svingebevægelse er sikret mod at falde ud af løftesvingarmparret. Dette er navnlig fordelagtigt i tilfælde, hvor beholderen rystes ved en hurtig, kort frem- og tilbagesvingning af løftesvingarmene, når disse befinder sig i det Øverste svingeområde.Hereby it is achieved that the container to be emptied has occasion 5 to perform a pivoting or tilting movement in both the one and the other direction with respect to the lift swing arm pair. The pivotal movement of the container in one direction relative to the lifting pivot arms corresponds substantially to the relative pivotal movement provided in the known mechanisms between the container 10 and the lifting pivot arms to the point where in the known mechanisms the parts of the support and locking mechanism are brought together. However, by the mechanism according to the invention, during this first relative pivotal movement, the container is secured against falling out of the lifting pivot arms by the supporting means entering one of the receiving means. In addition to the relative pivotal movement in the first direction, the container can also tilt in the opposite direction with respect to the lift pivot arms, whereby the container, when the pivot pivot arms are in the upper region of their pivotal motion, can be utilized by this possibility of the relative pivotal movement. in the other direction, it can still be tilted far past the angle corresponding to the swinging region of the lifting arms to improve emptying. During this second relative pivot movement, the support member moves into the second receptacle portion of the pickup member so that during this second relative relative pivot movement, the container is also secured against falling out of the lift pivot arm pair. This is particularly advantageous in cases where the container is shaken by a quick, short forward and reverse swing of the lift swing arms when they are in the Upper Swing Area.

30 I mange tilfælde kan beliggenheden af beholderens tyngdepunkt i forhold til bæreorganerne udnyttes til at frembringe den ved opfindelsen muliggjorte yderligere svingebevægelse af den beholder, der skal tømmes, i forhold til løftesvingarmene.In many cases, the location of the center of gravity of the container relative to the supporting means can be utilized to produce the further pivotal movement of the container to be emptied by the invention relative to the lift swing arms.

For imidlertid i alle tilfælde at opnå en sikker påbegyndelse 35 af denne anden relative svingebevægelse af beholderen i for- 149465 4 hold til løftesvingarmene kan mekanismen ifølge opfindelsen være udformet og indrettet som angivet i krav 2. I så fald kan mekanismen også udformes som angivet i krav 3. Den heri angivne fang- og anslagsarm kommer i så fald til at samvirke 5 med optageorganets anden optagedel og vil i almindelighed løbe ind i denne anden optagedel sammen med støtteorganet, men dette medfører ingen indbyrdes forstyrrelse af på den ene side fang- og anslagsarmen og på den anden side optageorganets to optagedele, idet støtteorganet snarere vil ramme fang- og 10 anslagsarmen allerede når det straks efter løftningen bevæger sig i mellemrummet mellem de to optagedele hen imod den nederste optagedel. På denne måde bidrager fang-2 og anslagsarmen til en sikker overføring af støtteorganet fra optageorganets første til dettes anden optagedel. Da der således 15 . består en berøring mellem fang- og anslagsarmen og støtteorganet over en forholdsvis lang svingevinkel for den beholder, der skal tømmes, er det derfor hensigtsmæssigt som angivet i krav 3, at anslagsarmen har en bueformet fang- og anslagskant med henblik på en i størst mulig udstrækning friktionsfri fø-20 ring af støtteorganet.However, in any case to obtain a safe onset of this second relative pivotal movement of the container in relation to the lift swing arms, the mechanism of the invention may be designed and arranged as set forth in claim 2. In that case, the mechanism may also be designed as set forth in claim 3. In this case, the catch and impact arm indicated herein will cooperate with the other recording member of the recording member and will generally run into this second recording member together with the supporting member, but this does not cause interference between the captive and the impact arm and, on the other hand, the two receiving members, the support means rather hitting the catching arm and the impact arm already when immediately after lifting it moves in the space between the two receiving members towards the lower receiving member. In this way, the catch-2 and the impact arm contribute to the safe transfer of the support member from the first receiving member to its second receiving member. Since there are 15. if a contact exists between the catch and impact arm and the support member over a relatively long pivot angle for the container to be emptied, it is therefore appropriate, as stated in claim 3, that the impact arm has an arcuate catch and impact edge for the greatest possible extent. frictionless feeding of the support member.

Ved den i krav 6 angivne udformning opnås, at spillerummene mellem på den ene side bæreorganerne og på den anden side optagedelene kan gøres betydeligt mindre end dersom optagedelene f.eks. var retliniede, og herved opnås en særlig sikker 25 indføring af støtteorganet og en sikker, jævn og friktionsfri styring af dette i optagedelene. En hensigtsmæssig udførelsesform for mekanismen ifølge opfindelsen er ejendommelig ved den i krav 7 angivne udformning. Herved opnås, en beholder, hvis tyngdepunkt ligger under området mellem bæreorganer-30 ne og støtteorganerne, først med det på beholderen anbragte støtteorgan eller -organpar bringes til anlæg mod den eller de svingelige fangkrog(e). Når løftesvingarmene svinges opad og dermed bringer støtteorganet eller -organerne på en sådan beholder ind i den øvre optagedel, frigives fangkrogen eller 35 -krogene og vil på grund af den allerede skete opadgående bevægelse af løftesvingarmen svinge ud af hvilestillingen og U9465 5 dermed frigive indgangen til den nedre optagedel, så at de videre bevægelser og funktioner kan forløbe på samme måde som ovenfor beskrevet, dvs. at den nedre optagedel er rede optage til at tillade den relative svingebevægelse af behol-5 deren i forhold til løftesvingarmene i det Øverste svinge-område. Denne virkemåde for fangkrogen eller -krogene kan på den nemmeste og gunstigste måde opnås ved den i krav 8 angivne udformning.In the embodiment of claim 6, it is achieved that the clearance between, on the one hand, the supporting means and on the other hand the recording parts can be made considerably smaller than if the recording parts e.g. were rectilinear, thereby providing a particularly secure insertion of the support member and a safe, smooth and frictionless control thereof in the receiving members. A convenient embodiment of the mechanism according to the invention is characterized by the embodiment of claim 7. Hereby, a container whose center of gravity lies below the area between the supporting means and the supporting means is first brought into contact with the supporting member or members of the container against the pivoting catch (s). When the lifting swing arms are pivoted upwards thereby bringing the support member (s) on such a container into the upper receiving part, the catch hook (s) 35 are released and, due to the already upward movement of the lift swinging arm, will swing out of the resting position and thereby release the entrance to the the lower recording portion so that the further movements and functions can proceed in the same manner as described above, ie. that the lower take-up portion is ready to allow the relative swinging movement of the container relative to the lifting swing arms in the upper swinging area. This operation of the catch hook or hooks can be achieved in the easiest and most favorable manner by the design according to claim 8.

Opfindelsen skal i det følgende forklares nærmere under hen-10 visning til det på tegningen viste udførelseseksempel på en mekanisme ifølge opfindelsen, idet fig. 1 viser mekanismen i sin nederste endestilling med en stor affaldsbeholder, som er kørt ind i mekanismen, fig. 2 viser mekanismen og beholderen i fig. 1 i den øverste 15 endestilling, hvor beholderen er løftet og vippet, fig. 3 viser en ændret udformning af de inden for området III i fig. 1 viste dele, og fig. 4 i perspektiv viser en svingarm med optagedele tilhørende den i fig. 1 og 2 viste mekanisme.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the exemplary embodiment of a mechanism according to the invention shown in the drawing. 1 shows the mechanism in its lower end position with a large waste container which is run into the mechanism; FIG. 2 shows the mechanism and container of FIG. 1 in the upper end position where the container is lifted and tilted; FIG. 3 shows an altered configuration of those within the range III of FIG. 1, and FIG. 4 is a perspective view of a pivoting arm with uptake portions belonging to that of FIG. 1 and 2.

20 Fig. 1 viser en løftemekanisme for store affaldsbeholdere i mekanismens nederste endestilling. Den store affaldsbeholder 1 er med sine på begge sider anbragte bæreorganer eller bæretappe 2 skudt ind mod de Øverste kæber i et par gribere 4, så at beholderen 1 kan løftes ved at svinge de to løftesving-25 arme 5 opad. Som det vil kunne ses af tegningen, er løftesvingarmene 5 lejret på en svingaksel 6, som er anbragt på et til en affaldsvogn 7 fastsvejset mellemstykke 8. Ved hjælp af en arbejdscylinder 9, som også er fastsvejset til affaldsvognen 7, kan løftesvingarmene 5 svinges opad gennem mere end 90°. I 30 hvert hjørne af overkanten er affaldsbeholderen 1 udstyret med et støtteorgan 10 i form af en til siden udragende tap. På indersiderne af løftesvingarmene 5 er der anbragt optageorganer 10a, der omfatter henholdsvis en øvre og en nedre optagedel henholdsvis 11 og 12, som ligger med indbyrdes afstand 11a.FIG. 1 shows a lifting mechanism for large waste containers in the lower end position of the mechanism. The large waste container 1, with its supporting members or support pins 2, is pushed against the upper jaws in a pair of grippers 4 on both sides, so that the container 1 can be lifted by swinging the two lifting swing arms 5 upwards. As can be seen from the drawing, the lifting swing arms 5 are mounted on a swing shaft 6 which is mounted on an intermediate piece welded to a waste truck 7 by means of a working cylinder 9 which is also welded to the waste truck 7, the lift swinging arms 5 can be swung upwards through more than 90 °. In each corner of the top edge, the waste container 1 is provided with a support member 10 in the form of a laterally projecting pin. On the inside of the lifting swing arms 5 are arranged receiving means 10a comprising an upper and a lower receiving part 11 and 12, respectively, spaced apart 11a.

Som vist i fig. 4 er der på indersiden af hver løftesvingarm 5 fastgjort en plade 41, til hvis nedre del der er fastgjort en L-formet liste 42, hvis stort set vinkelret på armen 5 forløbende flig 42a sammen med en stort set parallelt med armen 5 5 forløbende flig 42b danner den nedre optagedel 12. Foroven i den viste stilling af armen 5 er den her punkteret viste plade 41 forsynet med en u-formet liste 43, hvis åbning er rettet imod den nedre optagedel 12, og som udgør den øvre optagedel 11. Mellem underkanten af listen 43 og overkanten af fligen 42a 10 findes mellemrummet 11a til indføring af støtteorganet 10.As shown in FIG. 4, a plate 41 is attached to the inside of each lifting arm 5, to the lower part of which is attached an L-shaped strip 42, which is generally extending perpendicularly to the arm 5 extending arm 42 5 along with an arm substantially extending parallel to the arm 5 42b forms the lower receptacle portion 12. At the top of the shown position of the arm 5, the plate 41 shown here is punctured, provided with an un-shaped strip 43, the opening of which is directed towards the lower receptacle portion 12 and which constitutes the upper receptacle portion 11. Between the bottom edge of the strip 43 and the upper edge of the tab 42a 10 are the space 11a for inserting the support member 10.

Dersom løftesvingarmene 5 nu ved aktivering af arbejdscylinderen 9 bevæges så langt opad, at affaldsbeholderen 1 hænger frit i griberne 4, så går bæreorganerne 2 ind i griberne 4, og de inden for løftesvingarmene 5 beliggende støtteorganer 10 ind 15 i mellemrummet 11a. Når en videre opadgående svingebevægelse bevirker, at beholderens hjul kommer fri af underlaget, så har beholderen 1, der skal tømmes, mulighed for at vippe i forhold til de to løftesvingarme 5 både i den ene og i den anden retning. Alt afhængigt af beholderens størrelse og/eller ind-20 holdets fordeling bliver affaldsbeholderen 1 med sine pågældende støtteorganer 10 trykket ind i den øvre optagedel 11, eller ind i den i afstanden 11a herfra beliggende nedre optagedel 12, på det som en plade udformede optageorgan 10a.If, by actuation of the working cylinder 9, the lifting swing arms 5 are moved so far upwards that the waste container 1 hangs freely in the grippers 4, then the supporting members 2 enter the grippers 4, and the supporting members 10 located within the lifting swing 5 enter into the space 11a. When a further upward pivotal movement causes the container wheels to come free of the substrate, then the container 1 to be emptied has the possibility of tilting with respect to the two lifting pivot arms 5 in one and the other direction. Depending on the size of the container and / or the distribution of the contents 20, the waste container 1, with its respective supporting means 10, is pressed into the upper receiving part 11, or into the lower receiving part 12 located in the distance 11a, on the receiving member 10a formed as a plate. .

Mellem de to optagedele 11 og 12 er der svingeligt lejret en 25 fangkrog 13 for støtteorganet 10, hvilken fangkrog 13 er indrettet til i hvilestillingen af gribe ind i indløbet i den nedre optagedel 12 og til først at frigive dette indløb, når løftesvingarmene 5 henholdsvis beholderen 1 befinder sig i den indsvingede stilling. Ved hjælp af fangkrogen 13 - even-30 tuelt et par sådanne fangkroge - opnås for det første, at for store pendulbevægelser af affaldsbeholderen 1 under dennes indsvingning forhindres. For det andet opnås, at når beholderen er kort,eller lasten er ujævnt fordelt, dvs. at beholderindholdet medfører en uligevægt i det forreste område af be-35 holderen 1, så fanges støtteorganet 10 i løftesvingarmenes 7 149465 bageste svingeområde af fangkrogen 13, inden det kan komme ind i den nedre optagedel 12.Between the two receiving parts 11 and 12 there is pivotally mounted a catch hook 13 for the support member 10, which catch hook 13 is arranged for in the resting position of engaging the inlet in the lower receiving part 12 and to first release this inlet when the lift swing arms 5 and the container respectively. 1 is in the pivoted position. Firstly, by means of the catch hook 13 - possibly a couple of such catch hooks - it is achieved that excessive shuttle movements of the waste container 1 during its swinging are prevented. Secondly, it is obtained that when the container is short or the load is unevenly distributed, ie. the container contents causing an imbalance in the forward region of the container 1, then the support member 10 is trapped in the rear swing region of the lifting arms 7 by the catch hook 13 before it can enter the lower receiving part 12.

Fangkrogen 13 er udformet på en sådan måde, at når løftesvingarmene 5 befinder sig i deres midterste svingeområde, vil 5 fangkrogen 13 svinge tilbage under sin egen tyngde og dermed frigive støtteorganet 10, så at dette ved den anden relative svinge- eller vippebevægelse, som indtræder hen imod afslutningen af løftesvingarmenes opadgående svingebevægelse, kan løbe ind i den nedre optagedel 12, jfr. fig. 2.The catch hook 13 is designed in such a way that when the lifting swing arms 5 are in their middle pivotal region, the 5 catch hook 13 will swing back under its own weight, thus releasing the supporting member 10 so that by the second relative pivoting or tilting movement which occurs towards the end of the upward swinging movement of the lifting swing arms may run into the lower take-up part 12, cf. FIG. 2nd

10 I mange tilfælde er det muligt at udnytte beliggenheden af beholderens tyngdepunkt i forhold til bæreorganerne 2 til at udføre den ved opfindelsen opnåede anden relative svinge- eller vippebevægelse for beholderen 1, der skal tømmes, i forhold til løftesvingarmene 5.In many cases, it is possible to utilize the position of the center of gravity of the container relative to the support means 2 to perform the second relative pivot or tilting movement of the container 1 to be emptied in accordance with the invention relative to the lift swing arms 5.

15 Med henblik på at denne relative vippebevægelse af beholderen 1 i forhold til løftesvingarmene 5 i alle tilfælde kommer i gang, omfatter mekanismen et endeanslag 14 eller en fang- og anslagsarm 14a for beholderen 1 i den i fig. 2 viste øverste vippestilling, og anslaget eller armen ligger i en kortere afstand 20 fra løftesvingarmenes svingakse 6 end griberne 4, som optager beholderens bæreorganer 2. Som det vil kunne ses af tegningen, er endeanslaget 14 anbragt på en faststående del 15, som er fastgjort til affaldsvognen 7. Under den samlede vippefase befinder støtteorganet 10 sig i den øverste optagedel 11. Først ef-25 ter at støtteorganet 10 har ramt endeanslaget 14, udføres den anden relative vippebevægelse af bebeholderen 1, der skal tømmes, i forhold til løftesvingarmene 5. Herved slår støtteorganet 10 på beholderen 1 an mod endeanslaget 14, hvorved beholderen 1 under den videre opadsvingning af løftesvingarmene 30 5 tvinges til at foretage en svingning i forhold til løfte svingarmene 5. Det mod endeanslaget 14 fastholdte støtteorgan 10 flyttes derved fra den øvre optagedel 11 til den nedre optagedel 12. Eftersom beholderen 1 endnu skal foretage en forholdsvis lang svingebevægelse, medens støtteorganet 10 149465 8 ligger an mod endeanslaget 14, er sidstnævnte udstyret med en svingelig fang- og anslagsarm 14a, en afrundet fang- og anslagsnæse 16 og en dertil sluttet finger 17. Støtteorganet 10 opfanges først mellem fang- og anslagsnæsen 16 og 5 fingeren 17, og under den videre svingebevægelse af beholderen 1 svinges denne næsten friktionsfrit ved svingning af fang- og anslagsarmen 14a.In order for this relative tilting movement of the container 1 relative to the lifting swing arms 5 to start in all cases, the mechanism comprises an end stop 14 or a catch and stop arm 14a for the container 1 in the embodiment shown in FIG. 2, and the abutment or arm is at a shorter distance 20 from the pivot axis 6 of the lifting arms than the grippers 4 which receive the support means of the container 2. As will be seen from the drawing, the end stop 14 is mounted on a fixed part 15 which is fixed to the waste truck 7. During the overall rocking phase, the support member 10 is located in the upper receiving portion 11. Only after the support member 10 has hit the end stop 14 is the second relative tilting movement of the container 1 to be emptied relative to the lift swing arms 5. Hereby, the support member 10 on the container 1 beats against the end stop 14, whereby the container 1, during the further upward swing of the lift swing arms 30 5, is forced to make a swing relative to the lift swing arms 5. The supporting means 10 held against the end stop 14 is thereby moved from the upper receiving part 11 to the lower receptacle portion 12. Since the container 1 is yet to make a relatively long pivotal movement while the support member 1 Abutting the end stop 14, the latter is provided with a pivoting catch and impact arm 14a, a rounded catch and impact nose 16 and an associated finger 17. The support member 10 is first intercepted between the catch and impact nose 16 and 5 finger 17, and during the further pivotal movement of the container 1, it is pivoted almost frictionally by pivoting of the catch and impact arm 14a.

Som det fremgår af den i fig. 2 viste endevippestilling for beholderen 1, medfører den anden relative vippebevægelse, at 10 beholderen kan vippe langt forbi den vippevinkel, der svarer til det største udslag for løftesvingarmene 5, hvorved der kan opnås en væsentlig forbedring af beholderens tømning. Ved at under denne anden relative vippebevægelse både støtteorganet 10 og endeanslaget 14 løber ind i den anden, nedre op-15 tagedel 12, sikres den beholder, der skal tømmes, mod at falde ud af griberne 4, navnlig i de tilfælde, hvor løftesvingarmene 5 i nærheden af deres øverste svingestilling svinges hurtigt frem og tilbage med henblik på at ryste beholderen 1.As shown in the FIG. 2, the second relative tilting movement causes the container to tilt far beyond the angle of tilt which corresponds to the largest impact of the lifting swing arms 5, whereby a substantial improvement in the emptying of the container can be achieved. During this second relative tilting movement, both the support member 10 and the end stop 14 extend into the second, lower uptake portion 12, the container to be emptied is secured against falling out of the grippers 4, especially in the cases where the lift swing arms 5 near their upper swivel position, swivel back and forth quickly to shake the container 1.

Som det kan ses i fig. 1, befinder tyngdepunktet for affalds-20 beholderen 1 sig i området for bæreorganet 2. Den ændring i tyngdepunktets beliggenhed, som fremkommer på grund af lastens ujævne fordeling, kan udlignes ved hjælp af fangkrogparret 13, så at det også er muligt at tømme affaldsbeholderen 1, når tyngdepunktet har ændret beliggenhed. Ved hjælp af fangkrogen 25 henholdsvis fangkrogparret 13 er det muligt at opnå en sikker tømning af affaldsbeholdere, selv om disses tyngdepunkt allerede på forhånd ligger under området mellem bæreorganerne 2 og støtteorganerne 10. Når løftesvingarmene 5 svinges opad med en sådan, ikke vist beholder, vil beholderen ikke først 30 pendle ud, men støtteorganet 10 vil, straks efter at beholderen er løftet fri af jorden, komme til anlæg imod fangkro--gen 13.As can be seen in FIG. 1, the center of gravity of the waste container 1 is in the region of the carrier 2. The change in the location of the center of gravity, which is due to the uneven distribution of the load, can be offset by the catch hook pair 13 so that it is also possible to empty the waste container 1. , when the center of gravity has changed location. By means of the catch hook 25 and the catch hook pair 13 it is possible to achieve a safe emptying of waste containers, although their center of gravity is already in advance below the area between the supporting members 2 and the supporting means 10. When the lifting swing arms 5 are swung upwards with such a container, not shown. the container does not first commute 30, but the support means 10, immediately after the container is lifted off the ground, comes into contact with the catch hook 13.

I den ændrede udformning, der er vist i fig. 3, er endeanslaget 14 udformet som en cirkelrund skive eller rulle 14b, som i 9 149465 et lejested 15b er frit drejeligt lejret på tømmemekanismen.In the modified embodiment shown in FIG. 3, the end stop 14 is formed as a circular disc or roller 14b, which in a bearing location 15b is freely pivotally mounted on the emptying mechanism.

I den øverste svingestilling for løftesvingarmene 5 rammer støtteorganet 10 omkredsen af skiven 14b. Ved en videre opadgående svingebevægelse drejer skiven 14b, som nu understøtter 5 støtteorganet 10, sig i retning af pilen 16b. Beholderen løftes nu ikke højere, men ved den relative vippebevægelse mellem beholderen 1 og løftesvingarmene 5 drejer skiven 14b sig derpå i modsat retning af pilen 16b. Herved undgås enhver friktion mellem omkredsen af skiven 14b og støtteorganet 10.In the upper swing position of the lift swing arms 5, the support member 10 strikes the circumference of the disc 14b. In a further upward pivotal movement, the disc 14b, which now supports the support member 10, rotates in the direction of the arrow 16b. The container is now not raised higher, but by the relative tilting movement between the container 1 and the lifting swing arms 5, the disc 14b then rotates in the opposite direction of the arrow 16b. This avoids any friction between the circumference of the disc 14b and the support member 10.

10 På grund af skivens cirkelrunde form er funktionen uafhængig af skiven 14b’s udgangsstilling.10 Due to the circular shape of the disc, the function is independent of the starting position of the disc 14b.

Mekanismen kan også være udformet på anden måde end hvad der er vist i de ovenfor beskrevne eksempler. Således kan støtteorganet været udformet som en tværstang, og optageorganerne, 15 som er anbragt på løftesvingarmparret eller på beholderen, være udformet som en plade, hvori optagedelene og mellemrummet mellem dem er udformet som slidser. Optagemekanismen kan bestå af mindst én plade·, der er anbragt på en løftesvingarm eller på en beholderside, idet optagedelene udgøres af lister, der 20 er fastgjort til pladen.The mechanism may also be configured differently than shown in the examples described above. Thus, the support means may be formed as a transverse rod, and the receiving means 15 disposed on the lever swing pair or on the container may be formed as a plate in which the receiving members and the space between them are formed as slots. The recording mechanism may consist of at least one plate positioned on a lifting swing arm or on a container side, the recording portions being formed by moldings 20 attached to the plate.

I det viste udførelseseksempel vil fangkrogen 13, på grund af dens udformning og beliggenheden af dens tyngdepunkt, af sig selv svinge ud af indgangsområdet til den nederste optagedel 12, når løftesvingarmene 5 svinges opad. Indenfor opfin-25 delsens rammer er det imidlertid også muligt at frembringe en tvangsmæssig bevægelse af fangkrogen 13 til frigivelse af indgangsområdet til den nederste optagedel 12, f.eks. ved anvendelse af anslag eller andre organer.In the illustrated embodiment, the catch hook 13, due to its design and the location of its center of gravity, will naturally swing out of the input area to the lower receiving portion 12 as the lifting swing arms 5 are pivoted upward. However, within the scope of the invention, it is also possible to produce a forced movement of the catch hook 13 to release the entrance area to the lower receiving portion 12, e.g. by the use of projections or other bodies.

I de på tegningen viste udførelseseksempler er optagedelene 30 11 og 12 retliniede, hvad der gør deres fremstilling forholds vis billig. Imidlertid kræver den retliniede udformning betydelige spillerum mellem støtteorganet 10 og væggene i optagedelene 11 og 12. Disse spillerum kan formindskes væsentligt ved at udforme optagedelene 11 og 12 krumme med krum-In the embodiments shown in the drawing, the uptake portions 30 11 and 12 are rectilinear, which makes their manufacture relatively inexpensive. However, the rectilinear design requires considerable clearance between the support member 10 and the walls of the receiving members 11 and 12. These clearance can be substantially reduced by shaping the receiving members 11 and 12 with curved curves.
