Description

Područje izuma Field of invention

Ovaj izum spada u područje pribora za rad i namatanje pređe, a pogotovo se odnosi na uređaj za podupiranje kalema, čunjeva ili predivih kolača vrste za odmotavanje, drugim riječima uređaj koji se iskorištava u strojevima za odmatanje niti sa špula. This invention belongs to the field of accessories for working and winding yarn, and especially refers to a device for supporting spools, cones or yarn cakes of the unwinding type, in other words a device used in machines for unwinding threads from spools.

Stanje tehnike State of the art

Sve do sada, potpore za sredstva za namatanje pređe kao što su to kalemi, čunjevi ili predivi kolači u spomenutim strojevima bili su ostvareni pomoću uređaja koji su se u svojoj osnovi sastojali od rotirajućeg vretena, usmjerenog licem prema gore i krutom ručicom za oslonac, koja je nosila materijal za odmatanje. Cjelokupni sustav potpore pokazao se krutim i ukočenim, te je uzrokovao kvarove i probleme, koji su dobro poznati djelatnicima u tom sektoru rada. Until now, the supports for the yarn winding means such as spools, cones or yarn cakes in the mentioned machines have been achieved by means of devices which basically consisted of a rotating spindle, directed face up and a rigid arm for support, which was carrying the unwinding material. The entire support system turned out to be rigid and rigid, and caused breakdowns and problems, which are well known to employees in that sector of work.

U stvari, ako početni kalem nije cilindričnog već ovalnog oblika na primjer, može se dogoditi slijedeće prilikom njegove rotacije: In fact, if the starting coil is not cylindrical but oval in shape for example, the following can happen when it rotates:

- nejednaka napetost konca - trzajna nit; - unequal thread tension - jerky thread;

- vibracije u sustavu oslonca, pa čak i u stroju na kojem je uključen. - vibrations in the support system, and even in the machine on which it is turned on.

Posljedice su često previsoka napetost na zadnjoj špuli ili čak i učestalo kidanje niti, što itekako umanjuje kakvoću rezultata kod namatanja prede. The consequences are often too high tension on the last spool or even frequent thread breakage, which greatly reduces the quality of the results when winding the yarn.

Svrha i prednosti izuma Purpose and advantages of the invention

Svrha ovog izuma je stvoriti uređaj za potporu sredstvima za namatanje u strojevima za namatanje na špule/ koji bi zahvaljujući svojoj elastičnoj strukturi bio sposoban učinkovito prigušiti sve vibracije kod odmatanja, čak i kod neujednačenog odmatanja, čime se uklanjaju uzroci kvarova i problema tehničke prirode. Prednosti što iz toga proizlaze, uključuju i brzinu rada veću nego je uobičajeno bez kidanja niti, donoseći veću produktivnost i dobru kakvoću odmatanja prede u smislu ujednačenosti i pravilnosti kod napetosti namotajne niti. The purpose of this invention is to create a device for supporting winding means in spool winding machines/ which, thanks to its elastic structure, would be capable of effectively dampening all vibrations during unwinding, even in case of uneven unwinding, thereby eliminating the causes of failures and problems of a technical nature. The advantages that result from this include a higher than usual working speed without thread breakage, bringing higher productivity and good yarn unwinding quality in terms of uniformity and regularity in the tension of the winding thread.

Detaljni opis izuma Detailed description of the invention

Svrha i prednosti koje su gore navedene, postignute su prema izumu sa uređajem za potporu koji odgovara patentnom zahtjevu 1. The purpose and advantages mentioned above are achieved according to the invention with a support device corresponding to patent claim 1.

Detaljnije će se to vidjeti slijedom opisa učinjenim prema crtežima koji prikazuju izum ali ga ne ograničavaju, u kojima: This will be seen in more detail in the sequence of the description made according to the drawings which show the invention but do not limit it, in which:

Slika 1 prikazuje uređaj sa odvojenim vretenom; Figure 1 shows the device with a separate spindle;

Slika 2 prikazuje pogled na složen uređaj; i Figure 2 shows a view of the complex device; and

Slika 3 prikazuje uređaj sa varijantom sa prigušnim elastičnim sastavnim dijelovima. Figure 3 shows the device with a variant with damping elastic components.

Kao što je prikazano na tim slikama, uređaj uključuje potporanj 11, horizontalnu polugu 12, vertikalni elastični dio 13 i rotirajuće vreteno 14, koje preuzima i podupire namatanje prede, općenito označeno sa 15. Potporanj 11 može imati bilo koji oblik koji se nadopunjuje na dio , na koji je uređaj ugrađen za uporabu. Horizontalna poluga 12 je učvršćena tako da strši iznad potpornja 11 i elastična je; primjerice načinjena je od čelika za opruge ili od nekog drugog elastično savitljivog materijala. As shown in these figures, the device includes a support 11, a horizontal lever 12, a vertical elastic part 13 and a rotating spindle 14, which takes up and supports the winding of the yarn, generally indicated by 15. The support 11 can have any shape that complements the part , on which the device is installed for use. The horizontal lever 12 is fixed so that it protrudes above the support 11 and is elastic; for example, it is made of spring steel or of some other elastically flexible material.

Vertikalni elastični dio 13 je usmjeren od vrha prema dolje, počevši od horizontalne poluge 12 i nosi rotirajuće vreteno koje je također licem okrenuto prema dolje. Taj elastični sastavni dio 13 može biti oblikovan od košuljice 16 (slike 1 i 2) a napravljen od elastomernog materijala, te prema tome savitljiv i elastičan, ili može biti od bilo kojeg drugog elastičnog elementa kao što je opruga ili slično 17 (slika 3), ili čak od kombinacije elastomernih elemenata i opruge. Elastični sastavni dio 13 je ograničen na vrhu sa slobodnim krajem horizontalne elastične poluge 12, a na dnu sa krakom 18, na koji je rotirajuće vreteno 14 priključeno sa brzim spojnim utorom 19. The vertical elastic part 13 is directed from the top downwards, starting from the horizontal lever 12 and carries a rotating spindle which also faces downwards. This elastic component 13 can be formed from a liner 16 (pictures 1 and 2) and made of an elastomeric material, and therefore flexible and elastic, or it can be made of any other elastic element such as a spring or the like 17 (picture 3) , or even from a combination of elastomeric elements and a spring. The elastic component 13 is bounded at the top with the free end of the horizontal elastic lever 12, and at the bottom with the arm 18, to which the rotating spindle 14 is connected with the quick coupling slot 19.

Vreteno 14 i brza spojka 19 su sjedinjeni zajedno i zato ih ne treba detaljno opisivati. Treba samo napomenuti da je spajanje sa ležajevima 20, između vretena 14 i utora 19 predvideno na takav način, da vreteno može rotirati sa utorom 19 dozvoljavajući lagano skidanje vretena sa sustava oslonca (slika 1) kod održavanja, izmjene namotajne prede itd. Unutar okvira cjeline (vidi sliku 2) horizontalna poluga 12 dozvoljava prigušenje sila i vertikaine pomake namotajne prede kod namatanja niti pri vretenu. S druge strane, vertikalni elastični spoj 13 doprinosi prigušenju sila i poprečnih oscilacija u svim smjerovima kod namatanja na vretenu. Sve to eliminira nepotrebno i/ili nasilno istezanje prilikom odmotavanja pređe, čime se izbjegavaju problemi navedeni u prethodnom dijelu, omogućavajući postizavanje ciljeva, zbog kojih je izum i nastao. Spindle 14 and quick coupling 19 are united together and therefore do not need to be described in detail. It should only be noted that the connection with the bearings 20, between the spindle 14 and the groove 19, is provided in such a way that the spindle can rotate with the groove 19, allowing easy removal of the spindle from the support system (picture 1) during maintenance, changing the winding yarn, etc. Within the frame of the unit (see picture 2) the horizontal lever 12 allows damping of the forces and vertical displacements of the winding yarn when winding the thread at the spindle. On the other hand, the vertical elastic connection 13 contributes to the damping of forces and transverse oscillations in all directions when winding on the spindle. All this eliminates unnecessary and/or violent stretching when unwinding the yarn, which avoids the problems mentioned in the previous part, enabling the achievement of the goals, for which the invention was created.
