Abstract
U svom završnom radu govorim o održavanju, zastojima, greškama, poboljšanju produktivnosti na stroju za šivanje koncem otisnutih i savijenih araka Ventura. Ventura je stroj kojim mora upravljati strojar koji je školovan za taj dio dorade. Na stroju radi kvalificirani strojar koji ima pomoć ostalog ljudstva kod izlaganja sašivenih araka. Ukratko, stroj se sastoji od ulagaćeg aparata na koji se nalažu prethodno sabrani arci, arci pomoću usisnicima bivaju uvučeni i preuzeti sa hvataljkama. Hvataljke predaju arak transporteru arka koji arke vodi preko agregata za otvaranje. Sa usisnicima agregata za otvaranje arci se mogu po izboru otvarati od četiri puta sa prednje ili stražnje strane. Otvoreni se arak poliježe na pomoćno sedlo. Na pomoćnom sedlu nadolazeće arke kontrolira čitača glava, kako bi se vidjelo odgovara li redoslijed araka i da li su korektno otvoreni, te ih pomoću transportnog lanca prosljeđuje na sedlo za šivanje. Arci koje preuzimaju trake se poravnavaju i privedeni su u centar za šivanje. U centru za šivanje pojedinačni arci se šiju koncem u jedan knjižni blok, pri čemu se automatski separira svaki pojedinačni knjižni blok. Izlagaća stanica preuzima sašiveni odvojeni knjižni blok i transportira ga u slagač. U slagaču se knjižni blokovi slažu u kup i izbacuju na rol-traku. Tako sašiveni i odvojeni knjižni blokovi, spremni su za daljnju doradu.

| Abstract in english: | In this final thesis I will discuss malfunctions, errors and productivity improvements of the sewing thread machine for printed and bent sheet Ventura. Ventura is a machine which has to be managed by an engineer who is trained for work on it. The machine is operated by qualified engineer who has the help of other personnel when sewn sheets are exposed. In short, the machine consists of inserting device that requires a preassembled sheets, sheets are then drawn in using sauger and taken with Grapples. Grapples submit sheets to sheet conveyor which leads them over application for opening. With sauger units from application for opening sheets can be open four times from the front or the rear. Open sheet is laid on the auxiliary saddle. On auxiliary saddle upcoming sheets are being controlled by the reader's head to see whether the order of the sheets is suitable and correctly opened and then passed on to sewing saddle with transporting chain. Sheets taken by conveyor belts are getting aligned and brought into the center for sewing. In the center for sewing single sheets are sewn into single block, which are automatically separated. Exhibitor is taking over cells separate sewn block and transports it to a typesetter. In typesetter blocks are stacked on a pile and ejected to the conveyor belt. This way sewn and separated blocks are ready for further processing. |
