Vynález sa týká zariadenia pre změnusměru pohybu paliet a podložiek.The invention relates to a device for changing the direction of movement of pallets and washers.

Doteraz sa pre změnu směru pohybu prázd-ných paliet a podložiek používajú otočnéplošiny osadené hnanou valčekovou dráhous bočnými vedeniami a valčekové mostíkys náhonom valčekovej dráhy umiestnenýmna mostíku a zdvihom zabezpečovaným re-ťazovým prevodom. Otočné plošiny umo-žňu-jú iba přísun a odsun paliet po ich dížke,nakolko palety EUR umožňujú přechod povalčekoch iba v smere dosák na spodně]straně palety, v. důsledku čoho aj přísuno-vé a odsunové tratě sú riešené formou val-čekových dopravníkov. Pohyb paliet EUR povalčekových dráhách nie je plynulý, do-chádza k prešmykám a natáčaniu paliet, vdůsledku čoho valčekové dráhy musia byťosadené bočnými vedeniami, o ktoré paletytrú, prčiom dochádza. niekedy k spriečovaniupaliet vo vedeniach. Náběhy vedení bývajúzdrojom prerušenia pohybu paliet, alebo ichpoškodenia. Bočné vedenia dopravníkov bý-vajú umiestnené s vůlou cca 80 mm voči šír-ke palety v smere jej pohybu a preto aj boč-né výchylky a směrové odchýlky sú danéuvedenou vůlou. Z důvodu prešmvkov pale-ty pri pohybe po valcoch musí byť ich po-loha. v mieste změny směru dodatečné sní-maná a dorovnávaná v rámci vedení. Uve-dené nedostatky si vynucujú dodatočné zá-sahy obsluhy stroja a tým aj znižovanie vy-konav liniek. Valčekové mostíky umožňujúiba odsun paliet EUR z mostíka v smere zá-vislom od směru spodných dosák a směruosí valcov. Pri pohybe po valcoch dochádzak nrešmykom a kríženiu paliet, čo má zanásledok podobné nedczstatký ako u otoč-ných plošin.Until now, for changing the direction of movement of the empty pallets and washers, the rotary platforms fitted with the driven roller track are used by the side guides and the roller bridges are driven by the roller conveyor located on the bridge and the stroke provided by the chain drive. The swivel platforms allow only the supply and removal of pallets along their length, as the EUR pallets allow the loops to pass only in the direction of the plates on the bottom side of the pallet, as a result of which the feed and transfer lines are designed in the form of roller conveyors . The movement of the EUR pallets through the loaf tracks is not smooth, there is a rearrangement and rotation of the pallets, and as a result, the roller tracks have to be set by the side guides that the pallet takes place. sometimes to be called up in the lines. Leadings of conduits are a source of interruption of pallet movement or damage. The lateral guides of the conveyors are located with a clearance of about 80 mm relative to the width of the pallet in the direction of its movement and therefore the lateral deflections and the directional deviations are given by the aforementioned clearance. Because of the pangs of paleos when moving on the rollers, they must be in position. at the point of change of direction, additional reductions and calls within the management. The aforementioned drawbacks necessitate additional machine operator and hence reduction in line performance. The roller bridges allow the pallets to be displaced from the bridge in the direction of the lower deck direction and the roll direction. When rolling over the rollers, there is no slipping and crossing of the pallets, which results in a similar non-slippage as with the turntables.

Pohon valčekovej dráhy je umiestnený vráme zdvižného valčekového mostíka, v dů-sledku čoho je tento robustný, čo má vplyvna dimenzovanie pobonu zdvihu. Reťazovýnáhon zdvihu je náročný na umiestnenie po-honu a šponovania reťazového převodu, vdůsledku čoho je zariadenia zložité s vyso-kou relativnou hmotnostou voči hmotnostiprepravovanej palety alebo podložky.The drive of the roller track is located back to the lifting roller bridge, as a result of which it is robust, which has an influence on the dimensioning of the stroke extension. The chain drive of the lift is difficult to locate the drive and to chain the chain gear, as a result of which the device is complex with a high relative weight to the weight of the conveyed pallet or pad.

Tieto nedostatky odstraňuje zariadenie prezměnu směru pohybu paliet a podložiek po-dlá tohto vynálezu, pozostávajúce z odsu-nového reťazového dopravníka umiestnené-ho kolmo na přísunový reťazový dopravník,medzi reťaze ktorého zasahuje zdvižný re-ťazový mostík, zdvíhaný rotačným pohybomzdvihovej elektroprevodovky, prostredníct-vorn pákového převodu a hnaný rotačnýmpohybom pohonnej elektroprevodovky, pro-stredníctvom reťazového převodu vyznáču-júce sa tým, že zdvihový reťazový mostík jeoeadený hnaným reťazovým kolesom a vy-rovnávacím reťazovým kolesom, umiestne-ným otočné na konzole, pevne spojenej sozdvižným reťazovým mostíkom, na ktoromsú upevněné domce, z ktorých každý je u-1-o-žený otočné v ramenách pákového převo- du, spojeného prostredníctvom excentra svýhodným hriadelom zdvihovej elektropre-vodovky, uloženej v pevnom ráme, v spod-nej časti ktorého je uložená aj pohonná e-lektroprevodovka s naklínovaným hnacímreťazovým kolesom a vo vrchnej časti pev-ného rámu je otočné uložené dvojradové re-ťazové koleso a privarený úchyt s posuvnéupevněným čapom, na ktorom je otočné u-ložené šponovacie reťazové koleso, pričomreťazové kolesá sú spojené primárnou a se-kundárnou reťazou.These drawbacks are eliminated by the device changing the direction of movement of the pallets and pads of the present invention, consisting of a conveyor chain conveyor disposed perpendicular to the feed chain conveyor, between the chains of which the lift chain is extended, lifted by the rotary motion of the electro gearbox, through the gearbox. a lever transmission and driven by a rotary movement of the drive gearbox, by means of a chain drive, characterized in that the lift chain link is provided by a driven sprocket and a balancing chain wheel, which is rotatably mounted on a bracket fixedly connected by a chain link to which they are fastened house, each of which is rotatably mounted in the arms of a lever transmission, connected by means of an eccentric to a suitable shaft of a displacement electric motor, housed in a fixed frame, in the lower part of which is also a drive e-transmission gear unit with the wedge drive chain wheel and the upper part of the rigid frame is a rotatably mounted two-row chain wheel and a welded grip with a slidable pin, on which is mounted a pivoted sprocket, the chain wheels being connected by a primary and secondary chain.

Hlavně výhody zariadenia pre změnu smě-ru pohybu paliet a podložiek podlá tohtovynálezu spočívajú v tom, že umožňuje pří-sun a odsun paliet po- ich dížke i šírke ne-závisle od polohy dosák na spodnej stra-ně palety. Pohyb paliet počas přepravy jeplynulý, nedochádza k prešmvkom a natá-čaniu paliet a ich spriečovaniu, nakolkobočné vedenia nie je potřebné použit. Po-čas dopravy po reťazových dopravníkoch jevyhrčené poškodzovanie paliet alebo- podlo-žiek, pričom nedochádza k prerušovaniu po-hybu, pričom bočné a směrové výchylky súvylúčené, nakolko i počas dopravy paliet sauskutočňuje zr-ovnávanie polohy palety kri-vo položenej na přísunový reťazový do-pravník. Pohony zdvižného reťazového- mos-tíka sú umiestnené mimo něho v pevnomráme, v důsledku čoho má zdvižný reťazo-vý mostík jednoduchá konstrukční, čo mávplyv na nižší příkon pohonu zdvihu a přes-nost zastavovania v dolnej a h-ornej polohe.Šponovanie reťazového převodu je riešenév pevnom ráme běžným spůsobom. Zariade-nie je jednoduché, spolahlivé a má nízku re-latívnu schopnost voči hmotnosti prepravo-var’ej palety alebo podložky.In particular, the advantages of the device for changing the direction of movement of the pallets and the pads according to the present invention are that it allows the pallets to be brought in and moved along their length and width, irrespective of the position of the plates on the bottom of the pallet. The movement of the pallets during transport is smooth, there is no overspeeding and no palletizing, and no need to use them. The transport of the chain conveyors to the pallets is due to the damage to the pallets or the pads, while the movement of the pallets is not interrupted, while the lateral and directional deflections are avoided, as the pallet positioning on the feed chain is effected during the transport of the pallets. -lawyer. The chain hoist drive drives are located outside of it in a rigid, as a result of which the hoisting chain bridge has a simple constructional effect on the lower power input of the stroke drive and the stopping accuracy in the lower and h-arable positions. solved in a rigid frame in a conventional manner. The device is simple, reliable and has a low relative ability to the weight of the transport-cooking pallet or pad.

Na výkrese je na obr. 1 schematicky na-značené v nárvse prevedenia zariadenia po-dla tohto vynálezu vo východiskovej polo-he. po přisunutí palety nad zdvižný reťa-zový mostík.1 is a schematic representation of the embodiment of the device of the present invention in the starting half of the figure. after pushing the pallet over the lift chain bridge.

Zariadenie pre změnu směru pohybu pa-liet a podložiek pozostáva z odsunového re-fazového dopravníka 2 umiestneného kolmona přísunový reťazový dopravník 1, medzireťaze ktorého zasahuje zdvižný reťazovýmostík 5, zdvíhaný rotačným pohybom zdvi-hovej elektroprevodovky 11 prostredníctvompákového převodu 4 a hnaný rotačným po-hybom pohonovej elektroprevodovky 13 pro-stredníctvom reťazového převodu. Zdvižnýreťazový mostík 5 je osadený hnaným reta-zovým kolesom 6 a vyrovnávacím reťazovýmkolesom 7 umiestneným otočné na konzole8 pevne spojenej so zdvižným reťazovýmmostíkom 5.The device for changing the direction of movement of the trays and pads consists of a retracted conveyor 2 placed on the upright feed chain conveyor 1, the inter-chain of which extends the lift chain 5, lifted by the rotational movement of the lift gear 11 via the lever transmission 4 and driven by the rotary drive drive. an electric gear 13 through a chain drive. The lift chain bridge 5 is fitted with a driven chain wheel 6 and an alignment chain wheel 7 positioned rotatably on the bracket 8 fixedly connected to the lift chain 5.

Na tomto zdvižnom reťazovom mostíku 5sú upevněné aj domce 9, z ktorých je kaž-dý uložený otočné v ramenách pákovéhopřevodu 4, spojeného prostredníctvom ex-centra 10 s vývodovým hriadelom zdviho-vej elektroprevodovky 11 uloženej v pevnomráme 12. V spodnej časti pevného rámuHouses 9 are also mounted on this lifting chain bridge, each of which is rotatably mounted in the arms of the lever gear 4, connected by means of an ex-center 10 to the output shaft of the lifting gear 11 mounted in the fixed frame 12.

238746 12 also houses an electrically driven gear 13 with a keyed drive chain cog 14, and a double-row chain wheel 15 and a welded handle 16 with a slidably fixed pin 17 are rotatably mounted in the upper part of the fixed frame 12, on which it is about -spinning chain sprocket18. The chain wheels 14 and 15 are connected by a primary chain 19 and the sprockets 6, 15, 17 and 7 are connected by a secondary chain 20. During insertion of the pallet or pad, the lift chain 5 is in the lower starting position. Inches of the feed chain conveyor 1 push the pallet slideways, as a result of which they are aligned in a direction perpendicular to the direction of movement. The position of pushing the pallet over the lift chain bridge is determined by the stepping cycle of the feed chain conveyor 1, which slides the pallet with an accuracy of + 10 mm, and when the pallet position is reached, the feed chain conveyor 1 returns about 100 mm to prevent further interference movement of the pallet. Thereby, the stepper device gives the stroke of the stroke gear 11 and, by means of the eccentric 10 and the lever gear 4, lifts the lift chain bridge 5 to the upper position, thereby also lifting the pallet approximately 20 mm above the sliding guide of the feed chain conveyor 1. During the stroke of the chain bridge 5, the electric transmission 13 is switched off, as a result of which the sprockets K, 15 and 18 do not rotate. In this case, however, the chain-link chain wheel 10 is shortened by the length of the chain wheel equal to the stroke size and the chain branch from the driven chain wheel 6 to the double-row chain wheel 15 is exactly matched to the length of the chain wheel. with stroke size. As a result, the driven chain wheel 6 and the balancer chain wheel 7 are partially rotated in the direction of the pallet withdrawal, whereby the pallet also slowly starts to withdraw during the stroke. Upon reaching the uppermost position of the lift chain 5, the drive electrical transmission 13 and the transfer chain conveyor 2 receive a pulse to move the pallet to the outfeed chain conveyor 2 to a certain distance so that the displaced pallet does not interfere with the supply of further. When the pallet is moved away, the lower link chain 5 returns to the starting position and the cycle can be repeated. The construction of the device for changing the direction of movement of pallets and pads according to this invention allows, in the case of reliable operation of the operator and avoiding the damage of pallets and pads, to change the high direction of movement along the width and length of the pallets, while minimizing deviations of movement directions transport, with a low weight of flat and production-intensive, allows to increase the use and performance of the line into which the apparatus of the present invention is incorporated.
