Description

Vynález so. týká zariadenia pro priečno strihanie pásikovitého materiálu pod rdznyra uhlom střihu, najma obuvnických a galantérnych pásikov, pozostávajúce z podávacieho, strihacíeho a otočného mechanizmu.The invention so. relates to a device for transversally cutting strip-like material under different shear angles, in particular footwear and haberdashery belts, consisting of a feeding, cutting and rotating mechanism.

Pásiky z kožených, alebo plastických materiálov sa v značuej miere používajú v obuvníckom alebo galantérnom priemysle na konštrukcia zvršku obuvi, či. galantérne výrobky. Tieto pásiky sa strihajú na požadované dížku a uhol střihu je vedený na pozdížnú ^f,s pásika a je závislý od Sirky použitého pásika a tiež od zvolenoj konštrukcie obuvi, aby jeho dlžka v otvore pro stromčekové pfidovanie bola optimálna. Dopusial¹ sa strihanie pňsikov pod uhlom prevádzolo tým spósobom, že jedna pracovníčka ručně ceruzkou označovala podta plechovej šablony dížku a uhol střihu pásika a ďalšia pracovníčka ručně nožnicami, asi 40 metrov dlhý pásikovitý materiál, už označený střihala. Boli pokusy skonštruovať zariadenia pre strihanie kolmo na pozdížnu os a dížka sa nastavovala ručným posunutím. Takéto sposoby výroby boli náročné na pracovně sily, čiže málo produktivně aj vzhíadom na značný rozsah použitia pásikov.Belts of leather or plastic materials are used extensively in the shoe or haberdashery industry for the construction of shoe uppers, or. haberdashery products. These strips are cut to the desired length and the shear angle is directed to the longitudinal ^f, s of the strip and is dependent on the width of the strip used and also on the chosen design of the shoe to optimize its length in the tree opening. Dopusial ¹ , the cutting of the angles was carried out in such a way that one worker by pencil marked the length and angle of the strip under the sheet metal template and the other by hand scissors, about 40 meters long striped material, already marked. There have been attempts to construct shear devices perpendicular to the longitudinal axis, and the length is adjusted by manual translation. Such manufacturing methods have been labor intensive, i.e. not so productively and because of the wide range of tapes used.

Uvedené nedostatky odstraňuje zariadenie pre priečne strihanie pásikovitého materiálu pod róznym uhlom podía vynálezu. JehoThe above-mentioned drawbacks are overcome by the device for cross-cutting the strip-like material at a different angle according to the invention. his

I podstata spočívá v tom, že sa skládá z podávacieho, strihacieho a otočného mechanizmu, pričom podávači mechanizmus je tvořený týčou v spodnej časti so závitom, na ktorom je presuvne uchytená zarážka pohvbujúca sa v zvislom smere pri otáčaní ručného kolieska. Druhá zarážka je pevne spojená s piestnou týčou pneumatického valca a tiež s ozubenou týčou, ktorá sa pohybuje v zvislej rovině v drážke došky.In essence, it consists of a feeding, cutting and rotating mechanism, wherein the feeding mechanism is formed by a rod at the bottom with a thread, on which a stop engaging in a vertical direction is rotatably engaged when the handwheel is rotated. The second stop is rigidly connected to the piston rod of the pneumatic cylinder as well as to the rack which moves in a vertical plane in the groove of the thatch.

Priamočiary pohyb ozubenej tyče sa cez ozubené koleso prevádza na otáčavý, a to je pomocou hriadeia spojené s podávacím kolesem pásikovitého materiálu. Tlak naň vyvodzuje přítlačné koliesko cez pružinu. Pozdížna os prestavitelných vodítok do šířky smeruje medzi strihacie nožíky. Střihači mechanizmus je tvořený výkyvným ramenom, na ktorom je střihači nožík. Rameno je otočné uchytené vo vidlici a tá vo výkyvné uchytenom pneumatickom válci, kde na jeho piestnej tyči je upevněná vidlica a v nej otočné uchytená tyč, ktorá je pevne spojená s hriadelou, ktorá je pevne spojená s hriadelou, ktorá otáča celý střihači mechanizmus. Uhol střihu sa nastavuje na oblúkovitom ramene, v ktorom sú drážky pre kočky, ktoré vymedzujú uhol střihu pri pohybe zarážky.The linear movement of the toothed rack through the gear is converted into a rotary one, and this is connected to the feed wheel of the strip-like material by means of a shaft. Pressure is exerted by the pressure wheel through the spring. The longitudinal axis of the adjustable guides extends in width between the shear blades. The shearing mechanism consists of a swinging arm on which the shearing knife is mounted. The arm is pivotally mounted in a fork and that in a pivotally mounted pneumatic cylinder where a fork is mounted on its piston rod and a pivotally attached rod that is rigidly connected to a shaft that is rigidly coupled to a shaft that rotates the entire shearing mechanism. The shear angle is set on an arcuate arm with cat grooves that define the shear angle when the stop is moved.

Účinky vynálezu sa prejavujú v takom sklbení podávacieho, strihacieho a otočného mechanizmu spolu s ovládacou jednotkou, že podstatné niekoikonásobne zvyšujú produktivitu práce, odstraňujú ručnú namáhavú prácu a zvyšujú kultúrnosť pracoviska. Jednoduchá obsluha, vysoká produktivita a spolahlivý chod zariadenia sú hlavně přednosti zariadenia. Dížka pásika sa nastavuje vložením plechovej šablony medzi zarážky na tyči so závitom a otáčaním ručného kolieska sa nastaví požadovaná dížka pásika. Šířka v prestaviteTných vodítkách sa tiež nastaví otáčaním ručného kolieska na vodítkách. Uhol střihu sa nastavuje na oblúkovitom ramene, a to premiestňovaním kociek do jednotlivých drážok.The effects of the invention are manifested in such an alignment of the feeding, cutting and rotating mechanism together with the control unit that they substantially increase labor productivity several times, eliminate manual labor and increase the culture of the workplace. Simple operation, high productivity and reliable operation are the main advantages of the device. The strip length is adjusted by inserting a sheet metal template between the stops on the threaded rod and turning the hand wheel to set the desired strip length. The width in the adjustable guides is also adjusted by turning the handwheel on the guides. The cutting angle is adjusted on the arched arm by moving the cubes into individual grooves.
