Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for conditioning a roving or a fiber sliver in a spinning machine, and a spinning machine, particularly a ring spinning machine, for carrying out the method.

[0002]

In order to achieve satisfactory spinning results, the bobbins to be processed or wound are conditioned in a ring spinning machine, for example at a temperature of 28 ° C. and a relative humidity of 50%. It is already known that it is necessary to be surrounded by the atmosphere. Also, a larger value, such as 6
Air humidity of 0% is naturally conceivable.

In order to generate such a temperature- and humidity-controlled atmosphere in the area of the roving bobbin, it is a conditioning treatment, that is, a temperature and humidity adjustment of the atmosphere of the entire spinning hole, that is, German Utility Model No. 8908921. Known and commonly used. Further, in order to reduce the energy consumption for conditioning the entire spinning hole, an attempt has been made to first supply the temperature-humidity adjusted air to the vicinity of the roving bobbin to be temperature-humidity adjusted. It is also known from German Utility Model Registration No. 1969970.

Furthermore, a plurality of spinning units of the ring spinning machine are
It is also known from DE 1164286 A1 to contain a plurality of roving bobbins in a casing and load the casing in a temperature and humidity controlled atmosphere. However, this component makes the operation of the ring spinning machine extremely difficult and expensive. Further, in the case of such a configuration, it is necessary to supply temperature-humidity adjusted air to the entire inner chamber of the casing.

It is also possible to keep only the roving bobbin and the associated roving bobbin mounting creel in a single casing to keep it in a temperature and humidity controlled atmosphere.
It is known based on Japanese Patent No. 30.

However, in this case as well, the temperature- and humidity-controlled air must be supplied to the entire inner chamber of the casing,
The operation of the spinning machine, in particular the exchange of the roving bobbins, is more troublesome than in the case of equipment without casing.

In an open-end spinning machine, it is also possible to provide a spinning can with a fiber sliver with a central passage through which air having a predetermined temperature and a predetermined humidity is passed. Patent application publication No. 3
It is known from the specification of 919284. However, in this case, since the upper area of the spinning can is not adjusted for temperature and humidity, it takes time for the sliver to enter the open-end spinning machine. When spinning, there is a risk that it will no longer exist.

[0008]

SUMMARY OF THE INVENTION It is an object of the invention to enable the yarn to be optimally conditioned with a minimum consumption of the temperature-humidity adjusting medium during the particularly critical stages of the spinning operation with respect to the temperature and humidity conditions. Is.

[0009]

Means for Solving the Problems According to the constitution means of the present invention for solving the above-mentioned problems, at least a part of a roving yarn or a roving yarn bobbin and / or a roving yarn which extends from the roving yarn bobbin to a draft device and runs is provided. On the side, a medium whose temperature and humidity has been adjusted via one or more nozzles or jet orifices arranged in the immediate vicinity, and which is directly loaded before the medium mixes with the atmosphere around the nozzle or jet orifice. It is in.

[0010]

In summary, according to the present invention, the conditioning working medium, which is adjusted to the optimum temperature and humidity, passes through a pipe line which is completely closed until it comes into direct contact with the roving yarn bobbin or the roving yarn whose temperature and humidity are to be adjusted. Is particularly advantageous, since the conditioning medium comes into contact with the roving to be temperature-controlled and penetrates into the roving bobbin to a certain depth before being substantially mixed with the ambient air. It is. Therefore, an optimal conditioning state occurs in the area of the roving bobbin, even though the surrounding atmosphere has different hot and humid conditions. In this case, it is particularly important that the roving bobbin rotates during the operation of the spinning machine, so that the temperature / humidity adjusting air that is directly supplied uniformly loads the entire circumference of the roving bobbin, and the temperature and humidity are not adjusted in this range. It is possible to avoid a situation in which is left unreasonably. Optionally, a liquid, in particular water, may be sprinkled onto the roving yarn in finely divided form either as a spray jet or as a spray.

The roving yarn unwound from the roving yarn bobbin and fed out is drafted after a relatively short time, spun, and the spun yarn that is wound up as a cup is directly subjected to a conditioning treatment to obtain an optimum condition. A hot and humid condition is obtained, or the cups are virtually conditioned for each layer when they are wound, so the optimal temperature and humidity atmosphere is enclosed in the fully filled cups that have already been wound, and the next processing part For example, it is ensured that the warm and humid atmosphere is maintained for a relatively long time even when the cup is transferred to the repeater.

Conditioning air is 40 to 70%
It is particularly preferred to have a humidity of 50 to 60% and a temperature of 20 to 40 ° C, especially a temperature of 25 to 35 ° C.

The control means of the conditioning air flow from the roving bobbin to the drafting device and the spindle is ensured by means of the construction means according to claim 8 or 9, so that a high conditioning treatment efficiency is obtained and, consequently, the roving of the roving is obtained. In combination with the optimum conditioning treatment, the amount of conditioning air supplied directly to the roving bobbin or roving can be minimized, and the conditioning treatment can be performed satisfactorily with a small amount of energy consumption. become.

It is possible to adjust the water content of the conditioning air on the basis of the construction means according to the tenth or eleventh aspect. Therefore, while the optimum constant conditioning treatment of the roving yarn or the fiber sliver can be obtained by controlling in relation to the ambient temperature of the spinning hole, the number of yarn breakages is also reduced by the water content control.

The spinning machine for carrying out the conditioning treatment method of the present invention is as described in claim 12. Advantageous embodiments of the spinning machine according to the invention are specified in claims 13 to 22. The minimization of the amount of conditioning air supplied by the construction means according to claim 22 as well as an optimum conditioning treatment of the yarn are ensured.

The combination of the roving conditioning treatment method according to the invention with the central air suction method in the air guide chamber in the spindle area significantly reduces the temperature-controlled air, ie the heated and humidified air. The energy consumption is extremely reduced.
