Description

Uklad podawania sznurka zawiera pojemnik 35, z umieszczona wewnatrz szpula z nawinietym sznurkiem 42 oraz ma zabezpieczenie przed zaplatywaniem sie sznurka.Urzadzenie do wykonywania wezlów wedlug wynalazku dziala w sposób nastepujacy: najpierw ustawia sie glowice ruchoma R na zadana odleglosc od glowicy nieruchomej N. W przypadku wiazania parówek odleglosc ta jest równa batonowi parówki, a przy wiazaniu wedlin odstep ten powinien wynosic 15—30 mm tak, aby bylo mozliwe wykonanie dwóch wezlów obok siebie a po zwiazaniu przeciecie batonu miedzy tymi wezlami. Nastep¬ nie, na korbie mechanizmu korbowo-wodzikowego 17 nastawia sie wymagany skok przesuwu i dla przypadku wiazania parówek skok ten jest równy podwójnej dlugosci parówki, natomiast przy wiazaniu wedlin skok ten jest równy dlugosci batonu. Potem do stozkowej gardzieli wrzeciona 10 glowicy nieruchomej N podaje sie oslonke napelniona masa miesna i wklada ja az do wrzeciona 10 drugiej glowicy R. Teraz nastepuje uruchomienie napedu. Dzieki temu szczeki 13 zaciskaja baton, a szczeki 14 zwijaja sznurek 42 przechodzacy przez szczeke 11.Po wykonaniu przykladowo 2 obrotów przez szczeki 14, szczeka 12 (fig. 4) supla wezel przedstawiony na fig. 2, a potem odchylajac sie do tylu zaciaga ten wezel. W zaciagnieciu wezla i w odzyskiwaniu sznurka bierze udzial równiez szczeka 11, która jednoczesnie wybiera nadmiar sznurka. W tym czasie szczeki 14 sa uruchomio¬ ne. Po wykonaiu wezla szczeki 13 rozwieraja sie, kola 21 dokonuja przesuwu i cykl powtarza sie na nowo.W przypadku wiazania parówek szczeke 12 odlacza sie od krzywki 31 i cykl odbywa sie analogicznie do wyzej opisanego. W tym przypadku jest wykonywany wezel nietrwaly, przedstawiony na fig. 1, a kolejnosc operacji przedstawiona na fig. 8. Zarówno przy wiazaniu wedlin jak i parówek, szczeki 14 owijaja sznurek 42 wokól stozka 36 na wrzecionie 10 (fig. 5). W czasie suplania i zaciskania wezla trwalego lub nietrwalego sznurek 42 zeslizguje sie po zewnetrznej powierzchni stozka 36 i dostaje sie na baton, gdzie ulega ostatecznemu zacisnieciu. Szczeki 14 (fig. 5) sa sterowane krzywka czolowa 15, napedzana kolem 8, które obraca sie na nieruchomej rurze 43 wrzeciona 10. Szczeki 14 chwytaja sznurek 42 a sprezyna 37 zatrzaskuje szczeke i powo¬ duje obciecie sznurka na ostrzu 38. Obie szczeki 14 (fig. 5 i 6) pracuja na przemian przechwytujac kolejno sznurek.Dzialanie szczeki 12, pokazanej szczególowo na fig. 4, polega na tym, ze owijany przez szczeki 14 sznurek owija sie równiez wokól zamknietych ramion 39 i 40 szczeki 12. Po wykonaniu przykladowo dwóch owiniec, dzieki zadzialaniu krzywki 31, ramie 39 ulega rozwarciu i sznurek 42 niesiony przez szczeke 14 wchodzi w przestrzen miedzy ramionami 39 i 40. Nastepnie sprezyna 41 zastrzaskuje ramiona i szczeka 12 wykonuje obrót do dolu, tym samym zaciagajac wezel. W skrajnym polozeniu dolnym ramie 39 rozwiera sie i zostaje puszczona koncówka wezla, a szczeka 12 wraca w polozenie wyjsciowe. Poszczególne fazy charakterystyczne ruchów szczeki 12, podczas wykonywania wezla trwalego przy wiazaniu wedlin, przedstawiono na fig. 7 i odpo wiednio na fig. 8 - podczas wiazania parówek.4 78818 PLThe twine supply system comprises a container 35 with a twine spool inside 42 and has a twine-tuck-protection device. The knoting device according to the invention operates as follows: first, the movable head R is set to a predetermined distance from the fixed head N. In the case of When tying sausages, this distance is equal to a sausage bar, and when tying sausages, this distance should be 15-30 mm so that it would be possible to make two knots next to each other, and after tying the bar between these knots. Then, on the crank of the slider-crank mechanism 17, the required travel stroke is set, and in the case of tying sausages, the stroke is equal to twice the length of the sausage, while in the case of cured meats, the stroke is equal to the length of the bar. Then the casing filled with meat is fed to the conical throat of the spindle 10 of the fixed head N and it is inserted into the spindle 10 of the second head R. Now the drive is started. Due to this, the jaws 13 clamp the bar and the jaws 14 wind the string 42 through the jaw 11. After making, for example, 2 turns through the jaws 14, the jaw 12 (Fig. 4) knots the knot shown in Fig. 2, and then by bending backwards it pulls this node. The knot 11 is also involved in pulling the knot and retrieving the twine, simultaneously removing the excess string. During this time the jaws 14 are activated. After making the knot, the jaws 13 open, the wheels 21 move and the cycle is repeated again. In the case of tying the sausages, the jaws 12 are disconnected from the cam 31 and the cycle takes place analogously to the above described procedure. In this case, the non-permanent knot shown in Fig. 1 is made and the sequence of operations is shown in Fig. 8. In both tying sausages and sausages, the jaws 14 wrap the string 42 around the cone 36 on the spindle 10 (Fig. 5). As the knotting and tightening of a permanent or non-permanent knot is made, the string 42 slides over the outer surface of the cone 36 and enters the bar where it is finally tightened. The jaws 14 (Fig. 5) are controlled by a face cam 15, driven by a wheel 8, which rotates on a fixed tube 43 of a spindle 10. The jaws 14 catch the string 42 and a spring 37 latches the jaw and cuts the string on the blade 38. Both jaws 14 (Figs. 5 and 6) work alternately capturing the string one after the other. The operation of the jaw 12, shown in detail in Fig. 4, is that the string wrapped by the jaws 14 is also wrapped around the closed arms 39 and 40 of the jaw 12. When made, for example two wrappers, due to the action of the cam 31, the arm 39 opens and the string 42 carried by the jaw 14 enters the space between the arms 39 and 40. The spring 41 then strikes the arms and the jaw 12 rotates downwards, thereby tightening the knot. In its extreme position, the lower frame 39 opens and the end of the knot is released, and the jaw 12 returns to its starting position. The individual characteristic phases of the movements of the jaw 12 during the making of the permanent knot in the binding of cured meat are shown in Fig. 7 and, respectively, in Fig. 8 - during the binding of sausages. 4 78818 EN
