Description

Uppfinnare: 11 Rosqvist FOreliggande uppfinning avser en vaxel for hangbanor, sarskilt transportbanor i slakterier, charkuterifabriker m. m., innefattande tva vid var sin fasta skena i narheten av sin ena ande sviingbart anbragta skenelement, vilka vart och ett aro svangbara till och fran ett lage, i vilket ifragavarande skenelement med sin andra ande ansluter sig till en tiedje fast skena, och vilka Oro inbordes forbundna medelst ett arm- och lanksystem for tvangsmassig svangning av det ena skenelementet fran del namnda laget vid svangning av det andra skenelementet mot detsamma, och vice versa, varjamte vaxeln fir belastad medelst en svangbar vikt, som är genom svangning omstallbar for att halla det ena eller andra skenelementet i det namnda laget. Inventor: 11 Rosqvist The present invention relates to a gear unit for suspension tracks, in particular conveyor tracks in slaughterhouses, charcuterie factories, etc., comprising two rail elements arranged separately at each of their respective sides, each of which is pivotable to and from a layer, in which rail element with its second spirit connects to a fixed rail, and which concerns are connected by means of an arm and link system for forced pivoting of one rail element from the said team when pivoting the other rail element towards the same, and vice versa, each gear is loaded by means of a pivotable weight which can be adjusted by pivoting to hold one or the other rail element in the said layer.

En vaxel av detta slag visas i den danska patentskriften 77794, och vaxeln enligt 16- religgande uppfinning skiljer sig fran den dari avsedda vaxeln genom att det namnda arm- och lanksystemet utgores av ett par frail var sitt av skenelementen fritt uppskjutande, med det tillordnade skenelementet stelt forbundna armar och al" en armarna I deras fritt uppskjutande andar forbindande lank, vilken fritt 8verbryggar avstandet mellan namnda andar, varvid vikten Or fribarande lagrad pa den ena armen. A gear of this kind is shown in the Danish patent specification 77794, and the gear according to the 16th-existing invention differs from the gear intended therein in that the said arm and lance system consists of a pair of frail each of the rail elements freely projecting, with the assigned rail element rigidly connected arms and al 'en the arms In their freely projecting spirits connecting long, which freely bridges the distance between said spirits, the weight Or being free-bearing stored on one arm.

Harigenom har uppnatts en betydande forenkling av va.xeln, framfor alit genom att i vaxeln icke ingar nagot med hangbanans och vaxelns barkonstruktion forbundet lager for lagring av arm- och lanksystennet, sasom Or fallet betraffande den tidigare kanda vaxelii enligt det ovan namnda danska patentet; vid vfixeln enligt uppfinningen uppbaras armarna av skenelementen och fir lanken lagrad en-hart pa armarna. Tack vare att lagringspunkterna pa. barkonstruktionen ha eliminerats, kan vaxeln enligt uppfinningen monti.:- ras pa kortare avstand fran barkonstruktionen och Or antalet ingfiende delar mindre On vid den tidigare kanda vaxeln. Den Or dessutom lattare att inpassa i hangbansystemet On den tidigare kanda vaxeln. As a result, a considerable simplification of the shaft has been achieved, above all by the fact that the shaft does not contain any bearing connected to the suspension structure of the suspension track and the shaft for storage of the arm and longitudinal shaft, as in the case of the previously known shaft according to the above-mentioned Danish patent; in the case of the vfixel according to the invention, the arms are supported by the rail elements and the arm is mounted solely on the arms. Thanks to the storage points on. If the bar construction has been eliminated, the gear according to the invention can be mounted at a shorter distance from the bar construction and the number of engaging parts is less on the previously known gear. It Or also easier to fit in the hangban system On the former kanda gear.

I fortydligande syfte skall ett fordelaktigt utforande av uppfinningen i det foljande beskrivas narmare under hanvisning till bifogade ritning, pa vilken fig. 1 visar en planvy av en vaxel enligt uppfinningen, fig. 2 en sektion utefter linjen 2—.2 i fig. 1, sedd i pilarnas riktning, och fig. 3 en fragmentarisk andvy av det ena svangbara skenelementet. For the purpose of clarification, an advantageous embodiment of the invention will be described in more detail below with reference to the accompanying drawing, in which Fig. 1 shows a plan view of a gear according to the invention, Fig. 2 a section along the line 2-2 in Fig. 1, seen in the direction of the arrows, and Fig. 3 a fragmentary view of one pivotable rail element.

Den visade vaxeln lunar till godtycklig anslutning av en fast skena 10 till vilken som heist av ett par fasta skenor 11 och 12, vilka skenor 10-12 samtliga ha runt tvarsnitt och kunna ha vilken utstrackning som helst i sin langdriktning samt uppbaras av en barkonstruktion, exempelvis ett tak, vid vilken de aro fasta medelst konsoler 12. Skenan 10 befinner sig i linje med skenan 12 och kan anslutas till denna medelst ett rakt skenelement 14, som Or sa anbragt vid skenan 12 vid sin ena ande, att det Or svangbart kring en ungefar i 45° vinkel lutande axel 15 (se fig. 2). Skenan 11 bildar daremot huvudsakligen rat vinkel lined skenan 10, vilken Or anslutbar dartill medelst ett krokt skenelement 16, som Or sa anbragt vid skenan 11 vid sin ena ande, att det Or svangbart kring en horisontell axel 17. Svangforbindningarna mellan de fasta skenorna 11, 12 och de svangbara skenelementen 14, 16 kunna vara utformade pa vilket som heist kant salt, och detsamma galler anslutningsstallet mellan skenelementen och den fasta skenan 10, vilken senare exempelvis kan vara utformad med en stodansats f8r skenelementen, som kunna ha motsvarandc, stodansatsen inrymmande urtagningar i sin undersida. The gear shown shows an arbitrary connection of a fixed rail 10 to any hoist of a pair of fixed rails 11 and 12, which rails 10-12 all have a round cross-section and can have any extension in their longitudinal direction and are supported by a bar construction, for example a roof, to which they are fixed by means of brackets 12. The rail 10 is in line with the rail 12 and can be connected to it by means of a straight rail element 14, which Or said arranged on the rail 12 at one end so that it is pivotable about a shaft 15 inclined at an angle of 45 ° (see Fig. 2). The rail 11, on the other hand, forms a substantially right angle lined rail 10, which Or can be connected thereto by means of a curved rail element 16, which Or is arranged on the rail 11 at its one end, so that it is pivotable about a horizontal axis 17. The pivot connections between the fixed rails 11, 12 and the pivotable rail elements 14, 16 can be formed on any raised edge of salt, and the same applies to the connection stall between the rail elements and the fixed rail 10, which can later be formed, for example, with a stand shoulder for the rail elements, which may have corresponding groove housing recesses. in its underside.

PA den mot skenan 11 till belagna sidan om svangningsaxeln 17 Or det svangbara skenelementet 16 undertill stelt forbundet med en U-formig bygels 18 ena skankel, medan denna bygels andra skankel i sin fria ande medelst en svangtapp 19 Or fOrbunden med den ena anden av en lank 20, vars andra On-de medelst en kulled 24 Or fOrbunden med en vid undersidan av skenelementet 14 stelt 2— — fast, i vinkel bockad arm 22. Genom denna anordning aro de had. skenelementens 14 och 16 rorelser samoriinade pa sadant salt, att det ena skenelementet forskjutes till det lage, I vilket det ansluter sig till den fasta skenan 10, di det andra skenelementet forskjutes darifran, °eh vice versa. PA it against the rail 11 to the coated side of the pivot shaft 17 Or the pivotable rail element 16 rigidly connected to one shank of a U-shaped yoke 18, while the other shank of this yoke in its free spirit by means of a pivot pin 19 Or connected to one end of a lank 20, whose other On-de by means of a ball joint 24 Or connected to a at the underside of the rail element 14 rigid 2— - fixed, at an angle bent arm 22. By this device aro they had. the movements of the rail elements 14 and 16 coincide on such a salt that one rail element is displaced to the layer in which it adjoins the fixed rail 10, in which the other rail element is displaced therefrom, and vice versa.

Pa bygelns 18 med lanken 20 forbundna skankel fir en vikt 23 lagrad for svangning kring en horisontell axel. I det i fig. 1 och 2 visade laget stader denna vikt mot ett icke visat anslag pa bygeln och utovar darigenom pa skenelementet 16 ett vridmoment i moturs riktning med avseende pa fig. 2, sa att skenelementet 16 hMles i ett upplyft lage, medan skenelementet 14 daremot Mlles i det lage, i vilket det ansluter sig till den fasta skenan 10. Vikten 23 kan medelst en havarm 24 svangas medurs fran det i fig. 2 visade laget till ett ungefar 180° motsatt lage, i vilket den anligger mot ett annat, icke visat anslag pa bygeln 18 och darigenom utovar ett vridmoment i medurs riktning pa skenelementet 16, som darigenom Mlles i det lage, i vilket det ansluter sig till skenan 10, medan skenelementet 14 daremot Mlles i ett upplyft lage. Genom att skenelementets 14 svangningsaxel är anordnad i 45° lutning, svanges skenelementet 14 i ett mot vertikalplanet snedstallt plan, varigenom skenelementen 14 och 16 ga fria for varandra under svangningsrorelsen. On the shackle 18 with the length 20 connected shank for a weight 23 stored for pivoting about a horizontal axis. In the layer shown in Figs. 1 and 2, this weight rests against a stop (not shown) on the stirrup and thereby exerts on the rail element 16 a torque in the counterclockwise direction with respect to Fig. 2, so that the rail element 16 is hmles in a raised layer, while the rail element 14, on the other hand, Mlles in the layer in which it adjoins the fixed rail 10. The weight 23 can be pivoted clockwise by means of a sea arm 24 from the layer shown in Fig. 2 to an approximately 180 ° opposite layer, in which it abuts another , not shown abutment on the bracket 18 and thereby exerts a torque in the clockwise direction on the rail element 16, which thereby Mlles in the layer in which it connects to the rail 10, while the rail element 14 on the other hand Mlles in a raised position. Because the pivot axis of the rail element 14 is arranged at an inclination of 45 °, the rail element 14 is pivoted in a plane inclined towards the vertical plane, whereby the rail elements 14 and 16 are free of each other during the pivoting movement.
