Description
Vynález sa týká zariadenia na tuhé nabaTovanie rohože, pri ktorom napatie nabalovanej rohože priamo pčsobí na regulačný systém po celú dobu nabaTovania.The invention relates to a rigid mat loading device in which the tension of the rolled up mat directly acts on the control system throughout the loading period.
Doteraz známe systémy pracujú na týchto principech:Previously known systems work on the following principles:
Na zariadení vyrobenom vo Velkej Británii sa nabaTovanie prevádza odvarováním rohože po pogumovanom válci. Obvodová rýchlosť pogumovaného valca je zhodná s obvodovou rýchlosťou pása na výrobnom zariadení. Nad pogumovaný válec sa zasúva do vodiacich vidiel navíjecí trň opatřený dutinkou, na ktorú sa nabalí začiatok rohože. íialSie nabaTovanie sa , prevádza odvaTovanlm rohože po ťažnom, pogumovanom válci, pričom pri narastaní priemeru nábalu sa nabaTovací trň posúva vo vidliciach smerom nahor.On equipment manufactured in the United Kingdom, the loading is done by decoupling the mat after the rubberized roller. The peripheral speed of the rubberized roller is identical to the peripheral speed of the belt on the production equipment. A winding mandrel fitted with a sleeve over which the beginning of the mat is wrapped is inserted into the guide forks above the rubberized roller. The further loading is carried out by rolling the mat over the pulling, rubberized roller, and as the packing diameter increases, the loading mandrel moves upwards in the forks.
Nevýhodou tohto zariadenia je, že nábal nie je tuhý, jednotlivé závity sú od seba vzdialené a pdsobením vlastněj váhy sa rohož pri nabalovaní znehodnocuje. Ůalšírn nedostatkom je tu veTká spotřeba obalov spdsobená malou hustotou nábalov. Volný nábal sa prispOsobuje tvaru kartónu, čím sa rohož stává ťažSie spracovateTnou. Na skladovanie sú potřebné váčáie priestory a sú tu vySšie náklady na manipuláciu a přepravu. Obsluha pri nabalovaní musí stále sledovať kvalitu nabaTovania, nakolko dochádza k poruáovaniu synchronizácie medzi obvodovou rýchlosťou nábalu a výrobným zariadením.The disadvantage of this device is that the packing is not rigid, the individual threads are distant from each other, and due to the actual weight, the mat is depreciated during the packing. Another drawback is the large consumption of packaging due to the low packing density. The loose wrap adapts to the shape of the carton, making the mat more difficult to process. Vacuum space is required for storage and higher handling and transport costs. The operator must always observe the quality of the loading during the wrapping process as the synchronization between the peripheral speed of the wrapping and the production equipment is violated.

The floating rocker arm provided with a toothed segment »rotates with a toothed pinion and a potentiometer, as a result of which aa in the tyryator controller! for the driving electric motor. The basic charge level is set by manually controlling the tyros.tore controller.
Toto zariadenie je náročné nm přieetory. Hnací elektromotor má pri nízkých otáčkách malý záběrový moment, -z tohto dčvodu musí byť vysoko předimenzovaný, nakolko náraatoa nábalu klesajú obrátky nabalovacieho trňa a jeho krútiaei aoatat naraotá. Pri vyrovnávaní alučky počna regulovania dochádza k rozkladu aíl,če aepriazaive pftsobí aa regulačný systém. Okrem tohto nedostatku tu nepriaanivo pdaobia aj zotrvačné sily, v dfialedku čoho nie je tu aefaá navíjaf rohože a nižáou pevnoeťou.This device is demanding as far as possible. The drive motor has a low engagement torque at low revolutions, for this reason it must be highly oversized, as the speed of the wrapping mandrel decreases and the torque of the wrapping mandrel decreases and the torque is reduced. In balancing the alignment of the beginning of the regulation, there is a decomposition of the elements, which aepriazaive affects the control system. In addition to this deficiency, inertia forces are also adversely affecting here, at which point there is no aefaá winding of the mats and lower strength.
Uvedené nedostatky rieži zariadenie na tuhý nábal rohože pedla vynálezu, ktorého podstatou je prisma regulácia tahového napátia nabalovanéj rohože. Výkyvný regulačný ayztén je vytvořený výkyvnými raaenaai, naklinovanýai ne noanom hriadeli, uloženom v ložiskách. . ,The aforementioned drawbacks are solved by a rigid mat for wrapping a mat according to the invention, which is essentially based on the direct control of the tensile stress of the mat being rolled. The oscillating control ayztene is formed by oscillating raaenaai, pegged on a no shaft, mounted in bearings. . .
Výkyvná ramená sd v hornej časti opatřená vidlaai pre vloieaie nabalovacieho trňa, ťahadloa pre upevaenie vratného lana a ťahadloa opatřeným pružiaaai aa kompenzáciu preklopeaia. Vratná lano je opásaná na dvojčinných kladkách, čo zabezpečuje obrátaný směr tahu a dvojnásobný účinok sávažia. K druhému konců lana je upevněný ozubený hrebeň pre ovládanie tyrystorováho regulátora a na jeho predíženej časti sú nasunuté závažia pre stanovenie základného tahového napátia rohože.Swivel arms d at the top provided with a fork for insertion of a wrapping mandrel, a drawbar for attaching the return rope and a drawbar provided with a spring and a roll-over compensation. The return rope is wrapped on double-acting pulleys, which ensures a reverse pulling direction and double the effect of weighting. To the other ends of the rope there is a toothed rack for controlling the thyristor regulator and on its extended part weights are inserted to determine the basic tensile stress of the mat.
Ha predíienoa výkyvnoa raaene je upevněný váriítor, opatřený sériovým elektromotoroa a hnacím reťazovýa kolesom. V střede výkyvného raněna ja·otočná uložené reťazové a čelné ozubené dvojkcleeo, «pojené a variátoroa válečkovou reťazou. Celné ozubené koleso je v zábere e čelným ozubeným kolesom nabaHovaeieho trňa.In order to prevent oscillation, it is a fixed heater equipped with a series electric motor and a drive sprocket. In the center of the pivoting wound, the pivotally mounted chain and spur toothed double-knuckle, coupled and variator and roller chain. The entire gear is engaged by the front gear of the pickup mandrel.
Ťažisko výkyvnéj časti nabalovacieho zariadenia prechádza osou nosného hriadela a ná reguláciu aa využívá lan malé čaeť oblúka. Vplyv preklápacích sil v krajných polohách využívanéj časti- oblúka je kompenzovaný dveai tlačnými pružinami.The center of gravity of the pivotable part of the wrapping device passes through the axis of the support shaft and adjusts and uses a small arc part of the ropes. The influence of tilting forces in the extreme positions of the used part of the arc is compensated by two compression springs.
Použitím priaaej regulácia tahového napátia vyvodenáho závažím sa docieli vysokej citlivosti regulácia. Pri poklese obvodovéj rýchlosti na nábale ea vychýlia výkyvná raněná spojené cez ťáhadlá a lanom cez ozubený hrebeň ao závažím, pohyb sa prenesie cez ozubený hrebeň-na pastorok tyrystorováho regulátora, ktorý,urobí prúdovú korekciu a. sériový elektromotor zvýži otáčky. Pri náraste obvodovéj rýchlosti na nábale pracuje regulačný systém opačné, pričom sa využívá diferencia sily vývodená tahovým napátím v rbhoži oproti sile, ktorá je so závažím v rovnováha.By using a direct control of the tensile stress exerted by the weight, a high sensitivity control is achieved. As the circumferential velocity decreases on the embankment ea, the oscillating wounds connected via the draw rods and the rope through the rack and the weight, the motion is transmitted through the rack-to the pinion of the thyristor regulator, which makes the current correction a. the serial electric motor increases the speed. When the peripheral velocity increases on the ramp, the control system operates in the opposite direction, utilizing the difference of the force exerted by the tensile stress in the frame compared to the force that is in balance with the weight.
Pri náraste priemeru nábalu stúpa navíjací odpor a klesajú otáčky nabalovacieho trňa a narastá na ňom krútiaei moment. V sériovom elektromotor!dochádza k nárastu záběrového momentu. Momentová a prúdová charakteristika sériového elektromotore čiastočne spíňa požiadavku dodržania řovnakého napátia po celú dobu nábalu rohože. Diferenciu krútiaceho momentu zabezpečuje regulačné zariadenie, ktoré vykonává požadované prúdové ko205 104 rekcie pre sériový elektromotor.As the diameter of the packing increases, the winding resistance increases and the speed of the wrapping mandrel decreases and the torque increases. In the series electric motor, the starting torque is increased. The torque and current characteristics of the series electric motor partly satisfy the requirement of maintaining the same voltage throughout the mat's wrapping time. The torque differential is provided by a control device that performs the desired reaction current response for the serial electric motor.
