Den foreliggende opfindelse vedrører en postbehandlmgs-maskine og især en maskine som kan tømme en postcontainer og transportere indholdet i denne op på et arbejdsbord, samtidig med at det er muligt at tømme postsække på transportøren så-5 ledes at også indholdet af disse transporteres op på arbejdsbordet.The present invention relates to a mail-processing machine and, in particular, to a machine which can empty a mail container and transport its contents onto a work table, while at the same time it is possible to empty mail bags on the conveyor so that the contents thereof are also transported to worktable.

Post i form af breve og pakker ankommer normalt til postterminaler og budafdelinger i sække og containere, og før dette kan fordeles må det udlægges på et arbejdsbord eller 10 sorteringsbord. Almindeligvis tømmes containere og sække manuelt ud på et transportbånd som fører posten op på et sorteringsbord. Dette er en tidskrævende og besværlig proces, som desuden medfører store mængder post falder ud af containeren og ender på gulvet. Resultatet heraf er bl.a. en vanskelig og 15 ukomfortabel arbejdsstilling for de personer, som tømmer containere og sækkeMail in the form of letters and parcels usually arrives at mail terminals and courier departments in sacks and containers, and before this can be distributed it must be placed on a work table or 10 sorting table. Usually, containers and bags are emptied manually on a conveyor belt which carries the mail up on a sorting table. This is a time-consuming and cumbersome process that also causes large amounts of mail to fall out of the container and end up on the floor. The result of this is a difficult and uncomfortable position for people who empty containers and bags

Der kendes maskinelt udstyr som tømmer containere, men disse egner sig ikke til brevpost, idet dørene på containerne skal åbnes før containerne sættes på plads i maskinen, og 20 herved falder store mængder post ud hvorved den reelle fordel ved anvendelse af dette maskinelle udstyr til brevpost er særdeles lille Det er endvidere ikke muligt at tømme sække og containere samtidig ved anvendelse af denne maskine. Der findes endvidere tømningsudstyr som roterer containeren til-25 nærmelsesvis 180° for derved at tømme den gennem en åbning i toppen. Dette er imidlertid en maskine som af sikkerhedsmæssige hensyn må fastgøres til underlaget på grund af de kræfter og det drejemoment, der opstår ved at dreje en container fuldstændigt rundt. Denne løsning er med andre ord meget lidt 30 fleksibel, og desuden pladskrævende og kostbar.Mechanical equipment known as empty containers is known, but these are not suitable for letter mail, since the doors of the containers must be opened before the containers are put into the machine, and thus large quantities of mail fall out, thereby giving the real advantage of using this machine equipment for letter mail. is very small Furthermore, it is not possible to empty bags and containers at the same time using this machine. In addition, there are emptying equipment which rotates the container approximately 180 ° to empty it through an opening at the top. However, this is a machine that, for safety reasons, must be attached to the substrate due to the forces and torque generated by turning a container completely around. In other words, this solution is very little 30 flexible, and in addition space-consuming and expensive.

Af øvrige kendte løsninger kan der henvises til den tyske patentpublikation DE 3331898 der beskriver en maskmindret-ning for udtømning af pakker fra en container ved at dreje denne tilnærmelsesvist 180° og ved pakkerne udtømmes gennem 35 toppen af containeren Denne løsning har klare ulemper som DK 174131 B1 2 beskrevet ovenfor. En lignende løsning er beskrevet i tysk patentskrift DE 3433237Other known solutions refer to German patent publication DE 3331898 which describes a machine device for emptying packages from a container by rotating it approximately 180 ° and discharging the packages through the top of the container. This solution has clear disadvantages such as DK 174131 B1 2 described above. A similar solution is described in German patent specification DE 3433237

Endnu en løsning er beskrevet i EP 0562688 og udgøres af en ramme med en transportør samt en ved den nedre ende af 5 transportøren anordnet rampe som kan drejes tilnærmelsesvist 90° således at en postcontainer, hvis døre på forhånd er åbne, kan anbringes på rampen og tippes fremad over transportøren. For at hindre at posten falder ud af containeren før denne er anbragt i tømmepositionen er der på anordningen an-10 bragt en dør som lukker åbningen i containeren. Denne dør svinges bort når containeren har indtaget den korrekte position for tømning, således at posten falder ned på transportøren når lukkeanordningen åbnes. Denne løsning har imidlertid den ulempe at en del post vil blive liggende tilbage inde i 15 containeren, efter at denne er tømt Desuden bliver indretningen tung og kompliceret på grund af lukkeanordningen. Endvidere er det på grund af placeringen af den hydrauliske drejemekanisme for rampen ikke muligt at tømme postsække på transportøren.Another solution is described in EP 0562688 and consists of a frame with a conveyor as well as a ramp arranged at the lower end of the conveyor which can be rotated approximately 90 ° so that a post container whose doors are open beforehand can be placed on the ramp and tipped forward over the carrier. To prevent the entry from falling out of the container before it is placed in the emptying position, a door is provided on the device which closes the opening in the container. This door is swung away when the container has taken the correct position for emptying, so that the entry falls on the conveyor when the closing device is opened. However, this solution has the disadvantage that some mail will be left inside the container after it has been emptied. Furthermore, the device becomes heavy and complicated due to the closing device. Furthermore, due to the location of the hydraulic rotary mechanism of the ramp, it is not possible to empty mailbags on the conveyor.

20 Med henblik på at undgå ulemperne som er forbundet med de kendte løsninger indbefatter den foreliggende opfindelse en kombination af elementer som betyder at denne er fleksibel og sikker i brug, samtidig med at det er muligt at tømme postsække på den nedre del af transportøren, således at sækkenes 25 indhold transporteres op på et fordelingsbord uden særlig anstrengelse for operatøren. Det er endvidere muligt at anbringe postcontaineren med lukket dør inde i postbehandlmgs-maskmen, og derefter åbne døren når containeren er anbragt i en position hvor den er klar til tømning.In order to avoid the disadvantages associated with the known solutions, the present invention includes a combination of elements which means that it is flexible and safe to use, while at the same time it is possible to empty mail bags on the lower part of the conveyor, thus that the contents of the bags 25 are transported up to a distribution table without any special effort on the part of the operator. Furthermore, it is possible to place the closed door post container inside the post processing mask, and then open the door when the container is placed in a position where it is ready for emptying.

30 For at undgå de ovenfor nævnte ulemper udgøres den fore liggende postbehandlingsmaskine for tømning af postcontainere af en ramme som ved sin forreste del understøtter en transportør i den ene ende i niveau med et arbejdsbord og som ved den midterste del af rammen understøtter nævnte transportør i 35 den anden ende tilnærmelsesvist i gulvhøjde, og hvilken ramme ved den bageste del har en drejbart arrangeret rampe for mod- DK 174131 B1 3 tagelse af en postcontainer, og hvilken rampe har en anordning som fastholder postcontaineren, hvor postbehandlmgsma-skinen er kendetegnet ved at drejningspunktet for rampen er placeret i umiddelbar nærhed af den anden ende af transportø-5 rens understøttelsespunkt, og at rampen kan drejes om det nævnte drejepunkt ved hjælp af mindst en aktuator, hvilken aktuator i den ene ende er fastgjort i rammen i et punkt som er beliggende bag ved drejepunktet for rampen og at aktuato-rens anden ende er fastgjort til rampen. Den nævnte aktuator 10 kan f.eks. udgøres af en hydraulisk lineær aktuator. Da denne løsning ikke nødvendigvis behøver at fastgøres i underlaget, kan rampen understøttes på hjul, hvilket gør løsningen særdeles fleksibel idet samme postbehandlingsmaskine kan benyttes til at tømme post ud på flere forskellige sorteringsborde.In order to avoid the above-mentioned disadvantages, the present mail processing machine for emptying mail containers is constituted by a frame which at its front part supports a conveyor at one end at the level of a work table and which at the middle part of the frame supports said conveyor for 35 the other end approximately at floor height, and which frame at the rear has a pivotally arranged ramp for receiving a mail container, and which ramp has a device which holds the postcontainer, wherein the mail processing machine is characterized by the pivot point for the ramp is located in the immediate vicinity of the other end of the carrier point of support, and that the ramp can be rotated about said pivot point by at least one actuator, which actuator at one end is secured to the frame at a point located behind the turning point of the ramp and the other end of the actuator is attached to the ramp. Said actuator 10 can e.g. is a hydraulic linear actuator. Since this solution does not necessarily need to be fixed to the substrate, the ramp can be supported on wheels, which makes the solution extremely flexible as the same post-processing machine can be used to empty mail on several different sorting tables.

15 Endvidere er der ved denne placering af aktuatoren mulighed for at svinge rampen, og tømme postsække direkte på transportøren. Den foreliggende løsning er raed andre ord særdeles fleksibel og løser i al væsentligt de problemer og vanskeligheder der kendes i forbindelse med tømning af postcontainere 20 Med henblik på at forhindre at post ikke falder ud af containeren og ender på gulvet, rulles containeren på plads i rampen helt frem til enden af transportøren, før containerens dør åbnes, hvorved post som eventuelt falder ud af containeren når døren åbnes, falder direkte ned på transportøren og 25 derfra transporteres op på sorteringsbordet Der er endvidere anbragt to plader i overgangen mellem rampen og transportøren, hvoraf den ene plade glider tættende over den anden for at dække åbningen mellem rampen og transportøren, således at posten ikke falder ned i denne åbning Den ene plade er fast-30 gjort i rampen, og den anden er fastgjort i rammen15 Furthermore, at this location the actuator can swing the ramp and empty mailbags directly on the conveyor. In other words, the present solution is extremely flexible and essentially solves the problems and difficulties known in emptying mail containers 20 In order to prevent mail from falling out of the container and ending on the floor, the container is rolled into place in the ramp. right up to the end of the conveyor before the container door is opened, whereby mail which possibly falls out of the container when the door is opened falls directly onto the conveyor and from there is transported up to the sorting table. one plate slides tightly over the other to cover the opening between the ramp and the conveyor so that the entry does not fall into this opening. One plate is fixed to the ramp and the other is fixed to the frame.

Opfindelsen beskrives nærmere i det følgende med henvisning til tegningen, hvor fig 1 er et ovenbillede af et udførelseseksempel for anordningen ifølge opfindelsen, 35 fig. 2 samme som fig. 1 set fra siden, og fig 3 et snit langs linien A-A i fig. 1.BRIEF DESCRIPTION OF THE DRAWINGS The invention is described in greater detail in the following with reference to the drawing, in which: Figure 1 is a top view of an exemplary embodiment of the device according to the invention; 2 the same as FIG. 1 is a side view, and FIG. 3 is a section along line A-A of FIG. First

DK 174131 B1 4DK 174131 B1 4

Indretningen ifølge opfindelsen er opbygget omkring en ramme 1 på hvilken er anbragt en rampe 2 som er drejeligt fastgjort til rammen 1 omkring et drejepunkt 4. Rampen 2 er indrettet til at modtage postcontainere som kan sættes ind på 5 en bundplade 8 fra indretningens ene ende. Når postcontaineren er sat md på rampen 2 holdes den på plads i sideretnin-gen af sidebøjler 6 og forhindres i at vippe ved hjælp af en topbøjle 7.The device according to the invention is built around a frame 1 on which is mounted a ramp 2 which is pivotally attached to the frame 1 around a pivot point 4. The ramp 2 is arranged to receive post containers which can be inserted on a bottom plate 8 from one end of the device. When the post container is mounted on the ramp 2, it is held in place in the lateral direction by side hooks 6 and prevented from tilting by a top hanger 7.

Døren i postcontaineren kan herefter åbnes og rampen 2 10 drejes om drejepunktet 4 ved hjælp af en aktuator, som i figuren er anvist som en hydraulisk cylinder 5. Postcontainerens indhold vil så løbe ud af containeren og mod et transportbånd 9 som er anbragt til at føre posten op fra den position hvor den tømmes ud, dvs. nær gulvet, og op i arbejdshøj-15 de og eksempelvis ind på et andet transportbånd til sortering eller anden bearbejdning. På fig. 2 er indretningen vist med rampen 2 i sin nederste stilling hvor en container kan stilles ind på bunden 8 Desuden er rampen 2 opsvunget i tømme-position antydet med stiplet linie. Henvisningstallene til de 20 dele, som bevæger sig under drejning er angivet med henholdsvis 2^5^61 og 7'.The door in the post container can then be opened and the ramp 2 10 is turned about the pivot point 4 by means of an actuator, which is shown in the figure as a hydraulic cylinder 5. The contents of the post container will then run out of the container and towards a conveyor belt 9 arranged to carry the record from the position where it is emptied, ie. near the floor, and up to the working height and for instance onto another conveyor belt for sorting or other machining. In FIG. 2, the device is shown with the ramp 2 in its lower position where a container can be set on the bottom 8. Furthermore, the ramp 2 is swung in the emptying position indicated by a dotted line. The reference numbers for the 20 parts moving during rotation are indicated by 2 ^ 5 ^ 61 and 7 'respectively.

Som det fremgår af figurerne er drejepunktet for rampen 2 relativ lavt og anbragt omtrent i niveau med eller noget lavere end bunden af containeren. Dette sikrer at indretningens 25 tyngdepunkt selv under løft af containeren holdes lavt, således at indretningen er stabil under brug selvom den ikke er fastspændt til gulvet. Indretningen kan derfor være monteret på hjul 10 for intern transport i et postbehandlingsanlæg.As can be seen from the figures, the pivot point of the ramp 2 is relatively low and located approximately at or slightly lower than the bottom of the container. This ensures that the center of gravity of the device 25 is kept low even during lifting of the container, so that the device is stable during use even if it is not clamped to the floor. The device may therefore be mounted on wheels 10 for internal transport in a post-processing plant.

For at stabilisere indretningen under driften kan denne have 30 støtteben 11 som aktiveres når indretningen er i brug.To stabilize the device during operation, it may have 30 support legs 11 which are activated when the device is in use.

For at forhindre at post falder uden for indretningen under tømningen kan rammen 1 være forsynet med styreplader 12 som leder post ind mod transportbåndet 9. For at sikre at posten ikke falder ned i indretningen mellem transportbåndet 35 9 og rampen 2 er der på den viste indretning påmonteret lede plader 13,14 hvor den ene ledeplade 13 er fastmonteret på 5 DK 174131 B1 rammen 1 medens den anden ledeplade 14 er drejeligt ophængt i rampen 2 og beliggende over ledepladen 13 således at posten opnår en glat bane fra postcontaineren og ned på transportbåndet 9 5 Som det fremgår af snittet i fig 3 foretrækkes det at bunden 8 på rampen 2 er udformet med en forhøjning ved forkanten for at kunne modtage containere som normalt har understøtninger der er tilpasset for håndtering af containerne med en gaffeltruck. Bunden er således udformet at overkanten af 10 bundpladen på de anvendte containere er i flugt med eller lidt over højden af rampens forkant Samtidig skal containeren tilbageholdes således at den hindres i at glide for langt fremad.To prevent mail from falling outside the device during emptying, frame 1 may be provided with guide plates 12 which guide mail towards conveyor 9. To ensure that mail does not fall into the device between conveyor 35 9 and ramp 2, the device shown is mounted guide plates 13,14 where one guide plate 13 is mounted on the frame 1 while the other guide plate 14 is pivotally suspended in the ramp 2 and located above the guide plate 13 so that the post achieves a smooth path from the post container down to the conveyor belt 9 5 As can be seen from the section in Fig. 3, it is preferred that the bottom 8 of the ramp 2 is formed with an elevation at the leading edge in order to receive containers which normally have supports adapted for handling the containers with a forklift. The bottom is designed so that the top edge of the bottom plate of the used containers is in alignment with or slightly above the height of the front edge of the ramp. At the same time, the container must be held so that it is prevented from sliding too far forward.

I det viste udførelseseksempel kan indretningen efter at 15 postcontaineren er sat ind på bunden 8, styres af en operatør eksempelvis ved hjælp af et betjeningspanel 15 ved den øvre ende af transportbåndet 9.In the illustrated embodiment, the device, after the post container is inserted on the bottom 8, can be controlled by an operator, for example, by means of a control panel 15 at the upper end of the conveyor belt 9.
