Abstract

The invention relates to a method and an apparatus for correlating and controlling the travel rate of a belt within a vulcanization tunnel in respect of a rubber cord extrusion rate. According to the invention, the method consists in detecting the position of a loop of a rubber cord in free fall during the transfer from an extruder to a vulcanization tunnel, the so obtained data being then processed by a program installed on a computer which controls the extrusion rate increase or decrease, depending on the vulcanization rate. The claimed apparatus for carrying out the method comprises two transducers, each of them having one of two light-emitting fibres (1.1 and 2.1) and one of two light-receiving fibres (1.2 and 2.2) from a light slit, which detect the position of a cord (4) when interposing it in front of a light slit.

Description

„METODA SI APARAT DE CORELARE SI REGLARE TRANSFER ȘNUR EXTRUDER TUNEL,,„METHOD AND APPARATUS FOR CORRELATION AND ADJUSTMENT OF TRANSFER IN TUNER EXTRUDER,

Invenția se referă la o metoda si un aparat de corelare si reglare a vitezei de deplasare banda tunel vulcanizare cu viteza de extrudare șnur.The invention relates to a method and apparatus for correlating and adjusting the speed of movement of the vulcanizing tunnel band with the extrusion speed of the string.

Invenția este utilizata la utilajul de extrudare si vulcanizare șnur din cauciuc.The invention is used in the machine for extruding and vulcanizing rubber cord.

La utilajele existente controlul transferului șnurului de la extruder la tunel se face de către un operator prin reglarea manuala ,separata a vitezei de extrudare si cea de transport a tunelului de vulcanizare . Acest procedeu are dezavantajul supravegherii permanente de către un operatorAt the existing machines, the control of the transfer of the belt from the extruder to the tunnel is done by an operator by manually adjusting the extrusion speed and the transport of the vulcanization tunnel separately. This procedure has the disadvantage of the permanent supervision by an operator

Metoda ,conform invenției consta in utilizarea buclei pe care o face șnurul de cauciuc in timpul transferului de la extruder la tunel , prin sesizarea poziției buclei si a tendinței de creștere sau descreștere a acesteia in funcție de cele doua viteze .The method according to the invention consisted of the use of the loop made by the rubber cord during the transfer from the extruder to the tunnel, by noticing the position of the loop and its tendency to increase or decrease depending on the two speeds.

Aparatul conform invenției prevăzut cu senzori sesizează poziția șnurului si trimite semnale la un PC prevăzut cu placa de achiziție care prin intermediu unui soft, comanda creșterea sau descreșterea vitezii de extrudare .The apparatus according to the invention provided with sensors detects the position of the cord and sends signals to a PC provided with the acquisition board which, by means of a software, controls the increase or decrease of the extrusion speed.

Soluția propusa consta in a introduce un aparat care sa sesizeze poziția buclei de transfer a șnurului, vezi fig 1, si in funcție de aceasta poziție pe care o are bucla , un soft comanda creșterea sau scăderea vitezei de extrudare.The proposed solution consisted of introducing an apparatus that can detect the position of the loop transfer loop, see fig. 1, and depending on this position that the loop has, a software controls the increase or decrease of the extrusion speed.

Soluția are avantajul de a corela si regla automat transferu șnurului de la extruder la tunel, eliminând necesitatea supravegherii permanete si reglajele manuale dificile.The solution has the advantage of automatically correlating and adjusting the transfer of the string from the extruder to the tunnel, eliminating the need for permanent monitoring and difficult manual adjustments.

Se da în continuare un exemplu de realizare a invenției, în legătură cu figurile 1 si 2, In figura 1 se prezintă utilajul la care se aplica invenția . Utilajul se compune din un tunel de vulcanizare<l> si un extruder <2>. Extruderul produce un șnur <4> ,din amestecuri de elastomeri nevulcanizate . Șnurul este extrudat cu o anumita viteza <Nm >, reglabila , manual, sau ,automat, prin soft instalat pe o platforma pe un PC . Tunelul de vulcanizare preia șnurul pe o banda de transport care are o viteza reglabila, manual, sau automat, prin soft instalat pe o platforma pe un PC si care trebuie sa fie tot <Nm>. Compoziția elastomerului stabilește timpul de vulcanizare care determina viteza de deplasare a benzii de transport si care trebuie corelat cu viteza de extrudare .Following is an example of embodiment of the invention, in connection with Figures 1 and 2, In Figure 1 there is presented the machine to which the invention is applied. The machine consists of a vulcanization tunnel <l> and an extruder <2>. The extruder produces a <4> string from non-vulcanised elastomer mixtures. The nut is extruded with a certain speed <Nm>, adjustable, manually, or automatically by software installed on a platform on a PC. The vulcanization tunnel takes over the rope on a conveyor belt that has an adjustable speed, manually, or automatically, through software installed on a platform on a PC and that must be all <Nm>. The composition of the elastomer determines the vulcanization time that determines the speed of movement of the conveyor belt and which must be correlated with the extrusion speed.

Preluarea șnurului de la extruder la tunel se face printr-o bucla cu cădere libera .Extraction of the cord from the extruder to the tunnel is done through a free-falling loop.

Marimea buclei , poziția ei , evoluiaza in funcție de cele doua viteze . Când vitezele sunțThe size of the loop, its position, evolves according to the two speeds. When the speeds sound

2 -09- 2009 egale bucla are o poziție staționara , când bucla creste (scade ) inseamna ca viteza benzii este mai mare (mica ) fata de viteza de extrudare .

The vulcanization time being determined by the nature of the material, so the speed of the known band, the software determines according to the position of the loop of the extrusion speed.

Aparatul <3> din figura 1 se amplaseaza in zona de transfer a șnurului. Aparatul vezi figura 2 se compune din un suport pe care se amplaseaza doua perechi de senzori tip cortine opticecl.l, 1.2> si <2.1,2.2 > . Cortina optica este formata din un senzor optic prevăzut cu doua fibre optice care au la capete un emitator si un receptor de lumina .The apparatus <3> in figure 1 is located in the transfer area of the cord. The apparatus see figure 2 consists of a support on which two pairs of optical curtain sensors type l, 1.2> and <2.1,2.2> are located. The optical curtain is formed by an optical sensor provided with two optical fibers that have at the end a transmitter and a light receiver.

Șnurul se poziționează inițial intre cele doua cortine , aceasta fiind poziția de lucru .The cord is initially positioned between the two curtains, this being the working position.

Daca viteza creste sau scade șnurul urca sau coboara si intra in zona fantei de lumina a uneie din cortine , semnalizând acest lucru softului instalat in Pc care comanda revenirea la pozițiile normale de lucru .If the speed increases or decreases the rope goes up or down and enters the light slot of one of the curtains, signaling this to the software installed in the PC that commands the return to normal working positions.
