Abstract

Účelom vynálezu je automatické dvíhanie a presúvanie montážnych plošin z jednoho montážneho dopravníka na druhý. Uvedeného účelu sa dosiahne tým, že pneumatický válec opatřený piestnicou spojenou s unášočom hybné uloženým v drážke vytvorenej v základovej doske automaticky prevedie presunutie obojstranněj vačky. Přesunutím obojstrannej vačky sa uskutoční potřebné zdvihnutie a premiestnenie montážněj plošiny z jednoho montážneho dopravníka na druhý v íubovoínom smere. Vynález najlepšie charakterizuje obr. 1,2 a 3.The purpose of the invention is to automatically lift and move assembly platforms from one assembly conveyor to another. The stated purpose is achieved by a pneumatic cylinder equipped with a piston rod connected to a movable carrier mounted in a groove formed in the base plate automatically moving the double-sided cam. By moving the double-sided cam, the necessary lifting and moving of the assembly platform from one assembly conveyor to another in any direction is carried out. The invention is best characterized by Fig. 1, 2 and 3.

Uvedené nevýhody zmierňuje a daný technický problém rieši zariadenie na zdvíhanie a presúvanie montážnych plošin podía vynálezu, ktorého podstatou je, že pozostáva zo základovej došky pevne pripevnenéj o bočnice prvého a druhého montážneho dopravníka, pričom obidve bočnice sú v hornéj časti opatřené držiakmi, na ktorých sú otočné uložené krajné refazové kolesá. Pod základovou doslcou je umiestnený pneumatický válec opatřený piestnicou, ktorá je pevne spojená s unášačom hybné uloženým v drážke vytvorenej v základovej doske. Unášač je pevne spojený s obojstrannou vačkou opatřenou po stranách tvarovanými drážkami, tvořenými dolnými plochami, funkčnými plochami a hornými plochami. V tvarovaných drážkách sú vedené kladky otočné uložené na čapoch, ktoré sú otočné uložené v puzdrách a taktiež otočné a posuvné v zvislom smere na vodiacich hriadeíoch pevne uchytených na základovej doske. Puzdrá sú posuvné uložené na vodiacich hriadeíoch a pomocou osadení a otvorov vytvořených na nosnej časti sú pevne spojené s mostom. host je na vodiacej časti opatřený otočné uloženými hriadeími vo vodiacej časti mosta. Na hriadeíoch sú pevne upevněné refazové kolesá, ktorá spolu s krajnými refazovými kolesami otočné uloženými na držiaku, funkčnými refazovými kolesami otočné uloženými na pevných držiakoch a s náhonovým refazovým kolesom, taktiež otočné uloženým na pevnom držiaku sú opásané valčekovou refazou a tvoria uzavretý reíazový převod. Na koncoch hriadeíov sú po sti-anách vodiacej časti mosta pevne upevněné vodiace kladky.The above-mentioned disadvantages are alleviated and the technical problem is solved by the device for lifting and moving the assembly platforms according to the invention, which consists in that it consists of a base that is firmly fixed to the sides of the first and second assembly conveyors, both sides are provided with swivel mounted side impact wheels. Located below the base plate is a pneumatic cylinder provided with a piston rod which is rigidly connected to a carrier movably mounted in a groove formed in the base plate. The carrier is rigidly connected to a double-sided cam provided with grooves formed on the sides formed by lower surfaces, functional surfaces and upper surfaces. In the shaped grooves, the guided rollers are rotatably mounted on pins which are rotatably mounted in bushings and also rotatable and movable vertically on guide shafts fixedly mounted on the base plate. The bushings are slidably mounted on the guide shafts and are fixedly connected to the bridge by means of shoulder and holes formed on the carrier. the guest is provided on the guiding part with rotatably mounted shafts in the guiding part of the bridge. On the shafts are fixed fastened gears, which together with the outer gears are rotatable mounted on the holder, the functional gears are rotatable mounted on the fixed holders and with the driven gears, also rotatably mounted on the fixed holder are wrapped with a roller chain and form a closed chain. At the ends of the shafts, the guide rollers are fixedly fixed in the shade of the bridge guide part.

Výhodou zariadenia na dvíhanie a posúvanie montážnych plošin je, že mechanizmus je jednoduchý, nenáročný na obsluhu a hlavně spoíahlivý a taktiež že činnosf celého zariadenia je automatická a náv&znosfou na tok montážnych plošin po montážnom dopravníku podía udania adresy vyhodnocovaciernu středisku.The advantage of the device for lifting and shifting the assembly platforms is that the mechanism is simple, easy to service and above all reliable, and also that the operation of the whole device is automatic and depends on the flow of the assembly platforms along the assembly conveyor according to the address of the evaluation center.

Pneumatický válec 12 pohyhom piestnióe 13 dává do pohybu unášač 14. ktorý posunie obojstrannú vačku 15 tak, že kladka 16 se dostává v súčinnosÉ s hornými plochami, čím sa uskutoční zdvihnutie mostu 6. pomocou púzdra £· Zdvihnutím mostu 6 sa dostávajú vodiace kladky 27 do hornej polohy a uskutoční zdvihnutie montážněj plošiny 21 nachádzajúci sa na podpěrách 41 prvého montážneho dopravnxka 22. Vhíadom k tomu,^ že vodiace kladky 27 sa otéčajú prostredníctvom reíazového převodu, plošina sa dostává na druhý montážny dopravník 24 až po doraz 23. Zastavením montážnej plošiny 21 o doraz 23 vyšle koncový snímač 36 impulz pneumatickému valcu 12, ktorý oez piestnicu 13 a unášač 14 presunie obojstrannú vačku 28 do východiskovéj polohy, čím sa montážna plošina 21 dostane na podpěry 41 druhého montážneho dopravníka 24. Uvedená činnosí móžeme uskutečňoval podía potřeby v róznych smeroch pohybu montážnej plošiny 21.We assume that the lifting and moving device is in a convenient position (see FIGS. 1, 2 and 3), so that the mounting platform 21 is located on the supports 41 of the first assembly conveyor 22 in a static state, with the rollers 16 being located. On the lower surfaces 40 of the groove 28 of the double-sided cam 15, the device starts its operation so that the pneumatic cylinder 12 receives an impulse from the end sensor 36 and the sensor 19 reads the address and the evaluation center actuates the pneumatic cylinder 12. a carrier 14 which moves the double-sided cam 15 so that the pulley 16 interacts with the upper surfaces, thereby raising the bridge 6 by means of the sleeve 6. By lifting the bridge 6, the guide rollers 27 are brought up and lift the assembly platform 21 on the supports 41 of the first assembly conveyor 22. Since the guide rollers 27 are rotated by means of a chain transmission, the platform reaches the second assembly conveyor 24 up to the stop 23. By stopping the assembly platform 21 by the stop 23, the end sensor 36 sends a pulse to the pneumatic cylinder 12. and the carrier 14 moves the double-sided cam 28 to the starting position, whereupon the assembly platform 21 reaches the supports 41 of the second assembly conveyor 24. This operation can be performed as desired in the different directions of movement of the assembly platform 21.
