10 RETORCEDORA AND RING SPINNER AND USE OF A VOLATILE LUBRICANT FLUID IN A RETORCEDORA MACHINE AND RING SPINDLE.

OBJECT OF THE INVENTION

The invention, as expressed in the statement herein

descriptive, it refers to a method of lubrication ring-cursor in machines

twists and ring spinners, to a machine that applies said method, and to the use of lubricant in said machine.

The object of the present invention lies, on the one hand, in a new lubrication system of the ring-cursor assembly of the machines

ring twists or ring spinners, through the use of a fluid

So-called volatile lubricant, which is applied dosed in 25 very small quantities through a new dosing system

by means of a specific pump with which once the lubricating fluid has reached the ring and fulfill the function of ring-cursor lubrication, said fluid

lubricant volatilizes in the air, being a second aspect of the

invention the machine incorporating said dosing device for

30 applying said lubrication method, and, a third aspect the use of said type of volatile lubricants in the machine of said type.

FIELD OF APPLICATION OF THE INVENTION

5 The scope of the present invention is framed within the

industry sector dedicated to the manufacture of twisting machines

of rings or ring spinners, focusing particularly on the scope of the ring-cursor lubrication systems thereof.

10 BACKGROUND OF THE INVENTION

In the sector of twisting or spinning threads there are known continuous ring machines or ring twists where a cursor slides guided by the ring at a considerable ring-cursor friction speed

15 of 35m / sec at 45m1sec being always necessary to apply lubrication means to give a durability of cursor (which is considered a consumable) currently accepted by the sector and at a rate also accepted.

20 There are ring-cursor lubrication systems already known as the

wick, in which the lubrication is performed by fluid capillarity

lubricant from an external reservoir to the ring by means of said wick,

this method being limiting at the level of work speed and life of

cursor, since the capillarity provides a quantity of lubricating fluid

25 to the very limited system and not in accordance with the mechanical capabilities of

current development.

As a result of this limitation, new lubrication systems of the forced type emerged in which lubricating fluid is supplied to the ring by means of

30 pressure, see in US3593512 a direct dosage of lubricating fluid to the ring that has a greater ability to supply lubricating fluid and thus increase the speed limits of the cursor and also increase the life of the cursor in relation to wick lubrication.

However, a new phenomenon or collateral problem appears as a result of

this improvement that is not less important, the increase in the supply of

forced lubricating fluid causes a large part of fluid

lubricant that is supplied is not fully exploited and together with

that this type of circuit that is of the open type, all the lubricating fluid that

It is supplied to the ring, it spreads through the parts of the machine and at the end

lubricant on the floor and danger of slipping by factory personnel.

Subsequently, it has been innovating in the line of optimization based on

supply smaller amounts of lubricating fluid and better

spread over time, thus reducing the amounts of lubricating fluid

that are dosed to the ring (reduce the amount of lubricating fluid that will go to

stop to the ground) and at the same time increase the speed of the cursor and the

life of the same, but still the desired quantities to be dosed

needed to lubricate remain smaller and at the same time

the problem of the lubricating fluid to the ground is reduced but not eliminated, since

that over time (even longer) appears fluid again

25

Also, the applicant himself is the holder of the patent ES20000001315 that

discloses a refrigerator-lubricator cursor ring for said type of

machines in which a mixture of air and fluid is used as a lubricant

The objective of the present invention is therefore to develop a new method

of lubrication of the ring-cursor assembly and a machine with a new

5 dosing device that avoids this problem, that is to say, that avoids an excess of lubricant that causes undesirable drips and that at the same time allows to provide enough lubricant to be able to maintain or increase the speed of the cursor without causing premature

deterioration thereof.

10 On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, no other is known

method, machine or use of similar application or with technical characteristics, the same or similar to those presented in what is claimed here.

EXPLANATION OF THE INVENTION

The ring-cursor lubrication method in twisting machines and

ring spinning machines, the machine that applies said method, and the use of lubricant in said machine, are thus configured as a remarkable novelty

within its field of application that successfully reaches

objectives stated above, its details being characterized by

conveniently set out in the final claims that accompany the present description.

Specifically, what the invention proposes, as noted

previously, it is, on the one hand, a new method of lubricating the ring-cursor assembly of the ring or spinning machines

of rings comprising a lubrication stage of the cursor ring assembly 30 by means of a volatile lubricating fluid.

The use of a volatile lubricating fluid allows all or part of the volume of dosed lubricating fluid to evaporate when leaving the ring after a

some time. This circumstance reduces excess lubricant at the same time.

5

which allows adequate lubrication of the ring-cursor assembly.

\OR

A volatile fluid is characterized by its low viscosity, lower than ISO 10 est (at 40 'C). There are various types of volatile lubricating fluids such as those of vegetable or non-vegetable origin and each have a specific lubrication capacity and evaporation rate. Lubricating fluids of plant origin contribute to better environmental sustainability.

fifteen

In a preferred embodiment, the lubricating fluid is completely volatile. This embodiment prevents a part of the lubricant from falling to the ground. In a second embodiment the partially volatile lubricating fluid.

20 25

In cases where more lubrication capacity of the ring-cursor assembly is needed, the flow rate of 100% volatile lubricants can be increased, or another type of 100% volatile lubricant with a higher degree of lubricating capacity can be used , or the 100% volatile fluid can be added with additives and other (non-volatile) lubricants that improve said lubrication capacity. In this third case, the desired additivation should preferably be less than 15% by weight of the lubricating fluid although in some cases 30% has been added.

30

A second aspect of the invention is the twisting or ring spinning machine provided with a ring (1), in which a cursor (2) is attached, as a rail, which serves as a guide to the thread to be twisted, the gold-plated machine a new lubricant dosing system in the ring (1) comprising a pneumatically operated pump, preferably with a pneumatic source (3) of compressed air, preferably multipoint (the number of points can be between 3 and 50), which dose the volatile lubricant fiuido

to each point and leads / transports each ring-cursor assembly by means of pressurized air (preferably between 0.1 and 8 pressure bars).

Current lubricant dosing systems have a lower limitation that prevents dosing from being less than a certain volume per minute. This circumstance causes an excess of lubricant. He

lubricant dosing system object of this invention allows a lower dosage (average values of up to 0.001 cc per minute for each point) thanks to the regulation of pressure and pressurized air flow

output n combination with the dosing element regulation.

The ring (1), which can be made of a porous material or not, preferably has an outlet channel (7) of the volatile lubricating fluid directly in the inner part of the ring (1).

By way of comparison, in twisting or ring spinning machines

known and advanced oil quantities (lubricating fluid) of approximately 0.03 cc per minute are lubricated of which is used to lubricate 10% (90% falls to the ground). In the twisting or ring spinning machine object of the invention, when using 100% volatile oil, amounts of oil of approximately 0.01 cc per minute are lubricated of which 100% is used

for lubrication and no fraction falls to the ground.

A third aspect of the invention is a method for modifying a machine.

twist and ring spinner of which a fluid is used as a lubricant

non-volatile lubricant so you can use a fluid as a lubricant

volatile lubricant This modification method is characterized by

5 comprise a stage where the non-volatile lubricating fluid injection pump is replaced by a preferably multipoint pneumatic pump (4) (the number of points can be between 3 and 50), which doses the volatile lubricating fluid at each point and drive / transport to each

ring-cursor assembly by pressurized air (preferably find out

10 0.1 to 8 pressure bars).

This modification method allows machine owners

Twisting and ring spinners reduce the amount of lubricating fluid that falls without having to change the twisting and ring spinning machine

15 complete.

Finally, a fourth aspect of the invention is the novel use of said

type of volatile lubricating fluid in twisting and spinning machines

ring to lubricate ring-cursor set since it is not known until now

20 such use in said field of application, since it is a type of lubricants conventionally applicable in sectors very different from that of the invention,

for example that of the automotive industry.
