Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a heat treatment in which a bobbin yarn wound by a spinning machine, that is, a spinning bobbin, is conveyed to a hoisting machine,
The present invention relates to a spinning bobbin heat treatment method and apparatus for performing a steam setting step and a cooling / drying step after the step is completed.

(Prior art)

It is necessary to wind a spun yarn spun from raw cotton, raw wool, synthetic fiber sliver, or the like into a bobbin, and wind the bobbin yarn, that is, the spun bobbin, in units of corn cheese or parallel cheese using a hoist. However, in this step, when a new spinning bobbin is supplied to the hoist, it is necessary to join the spun yarn. However, at this point, if the spun yarn is not heat-treated, that is, not steam-set, the tip of the spun yarn drawn by the air flow is not aligned with the direction of the air flow due to the twisting torque during the spinning, and therefore the spun yarn is not. There is a problem that automatic joining cannot be performed.

Therefore, before supplying the spinning bobbin to the hoist,
We have a steam set.

Conventionally, the spinning bobbin as described above is randomly put into a predetermined box called a thread box, and the bobbin is put into a unit of a thread box and put into several tens of boxes. It is set. In this simultaneous steam setting method, the spinning bobbins manufactured in each spinning machine are once collected in a yarn box, transported to a place where the processing pot is located, steam set, and the spinning bobbin is taken out from the processing pot, A method of carrying the hoisting machine one by one to the shaft of the hoisting machine is adopted.

In such a spinning bobbin processing step, the steps of taking out the spinning bobbin from the spinning machine or attaching the spinning bobbin to the hoist are automated. However, even in these processes, a transport route is required in which a certain amount of spinning bobbins must be transported together to a processing tank, set with steam, transported to a hoist and wound up. .

In other words, the conventional spinning bobbin heat treatment method requires at least five devices: spinning machine → transportation device → steam setting device → transportation device → winding machine because the steam setting process is independent. .

From the configuration of the apparatus, a preparation step of packing a certain amount of bobbins in a bobbin box for supplying a spinning bobbin to a steam setting apparatus, supplying the bobbin box to a steam setting apparatus, a spinning bobbin completed with steam processing, That is, a series of steps such as unloading of the thread box are required, which complicates the steps and hinders the continuous processing of the spinning bobbin. The biggest problem causing this obstacle is that the steam setting process is an independent process.

On the other hand, among conventional heat treatment methods for various spinning bobbins,
The required processing time for vacuum heat treatment varies somewhat depending on the type of yarn wound on the spinning bobbin, for example, wool, blending of cotton and synthetic fiber, and the processing temperature and the time required for processing are somewhat different. In any case, if the number of spinning bobbins to be processed in a unit time increases, in the conventional continuous heat treatment equipment, if the installation location is considered between the spinning machine and the hoist, In addition, since the occupation area of the heat treatment apparatus becomes large, there arises a problem that processing cannot be performed.

Also, what should be noted in the steam setting process here is that the cooling and spinning of the spinning bobbin after the steam setting process is completed.
This is related to drying, and generally the temperature of the steam set is 60
The temperature is usually between ℃ and 80 ℃, much higher than room temperature, and the water is well supplied.

Under such conditions, the spun yarn wound on the spinning bobbin is
When the internal stress is released, the temperature is lowered as it is, the temperature is lowered, and when it is dried, it is fixed in its original shape, which is the purpose of the steam setting.

Therefore, if the temperature of the spinning yarn does not drop sufficiently and the machine goes to the hoisting machine with excess water remaining, automatic connection cannot be made because the yarn quality is not solidified. The spun yarn that has been set needs to be sufficiently cooled and dried, and the present invention has been devised to meet the need.

[Object of the invention]

The present invention has been made in order to eliminate that the steam setting step is independent in the heat treatment step of the conventional spinning bobbin, and that continuous processing is hindered in that step, and that the spinning bobbin is produced by a spinning machine.

It is an object of the present invention to provide a spinning bobbin processing method and apparatus that do not take the spinning bobbin.

〔Example〕

Hereinafter, an embodiment of a heat treatment apparatus to which the heat treatment method of the present invention is applied will be described with reference to the drawings. FIG. 1 is a plan sectional view of an embodiment of a heat treatment apparatus for a spinning bobbin of the present invention.
The figure is a front view in the II direction of FIG. 1, and FIG. 3 is an enlarged sectional view of the peck stand and the guide rail of FIG.

The heat treatment apparatus constituting this embodiment is a plurality of heat treatment tanks, that is, two heat treatment tanks 1 and 1 'are connected side by side as in this embodiment. It is installed on the roller 4.

In other words, the spinning bobbin 23 manufactured in the spinning process by the spinning machine 21 shown in FIG.
As shown in FIG. 3, two heat treatment tanks 1, 1 'which can be transferred and heat-treated while connected to the peck stand 30 are connected between the heat treatment tanks 1 and 1'. , 1 ′
While the spinning bobbin 23 is carried in and out of one of the tanks, a series of heat treatments of the spinning bobbin 23 transferred to another tank are performed.

Next, the operation of the heat treatment apparatus will be described. Assuming that two heat treatment tanks 1, 1 'are present at the positions indicated by arrows A and B in FIG. In the heat treatment tank 1 'located at the position B, the spinning bobbins 23 which have been subjected to the predetermined heat treatment are extruded three by one by the action of the pushing cylinder 7 from the inlet side conveyor 5, and the outlet side. It is sent out from the chute 8 to the exit side conveyor 9.

When the spinning cylinder 7 on the inlet side is stopped when the spinning bobbin 23 having completed the heat treatment step exits the heat treatment tank 1 ', the untreated spinning bobbin 23 is filled in the heat treatment tank 1'.

When the heat treatment step in the heat treatment tank 1 at the position A is completed, both the heat treatment tanks 1 and 1 'are driven by the cylinder 10 shown in FIG.

Then, the spinning bobbin 23 is pushed out from the heat treatment tank 1 at the position B by the push-in cylinder 7 on the inlet side by the new spinning bobbin 23 and sent out from the outlet side chute 8 to the outlet side conveyor 9 in the same manner as described above. The tank 1 is filled with a new spinning bobbin 23.

The heat treatment tank 1 'sent to the position C is closed by the cylinder 11 with the door 2' closed, and enters a series of steam setting steps of vacuum → steam heating → left for a certain time → re-vacuum → vacuum breaking.

What is important here is either the step of re-vacuum to vacuum break during the above-mentioned steam setting step, or the subsequent step of rapid cooling and drying by aeration cooling using low-temperature air supplied from the cold air generator 15. In this process, low-temperature air is also used, and after the steam setting, a series of heat treatments of cooling and drying by aeration cooling are performed, and the heat setting effect and the winding effect can be improved.

It is also important to provide a heat insulating plate 14 on the inner surface of the heat treatment tanks 1 and 1 'in order to prevent radiation from the heat treatment tanks 1 and 1'.

The heat insulating plate 14 is a metal foil attached along the inner walls of the heat treatment tanks 1 and 1 ', and has a small heat capacity and can effectively block radiant heat from the wall by stacking a number of sheets. Aluminum foil is preferred as the material for the metal foil.

Further, a header 16 shown in FIG. 2 is provided at the bottom of the heat treatment tanks 1 and 1 '.
When the steam setting is completed, the vacuum is broken from the header 16 with the low-temperature air, and the low-temperature air for ventilation cooling is blown out of the header 16 to cool the spinning bobbin 23.

Next, the movement of the spinning bobbin 23 will be described. The spinning bobbin 23 which is full and doffed in the spinning process by the spinning machine 21 is sent from the spinning machine 21 to the heat treatment tank 1, 1 '. When the direction is changed by the pusher cylinder 6 while being inserted into the peck stand 30 sent to the position shown in FIG.
Works and is pushed into the heat treatment tank 1 '(or 1).

By repeating the movement, the heat treatment tank 1 '(or 1)
Is filled with the peck stand 30 in which the full spinning bobbin 23 is inserted, moves to the position C (or the position A), and the door 2 '
After the (or 2) is tightened, it is connected to the heat treatment tank 1 '(or 1), and is necessary for heat treatment of the vacuum pump 12, the steam generator 13 and the like installed above the heat treatment tanks 1 and 1'. By operating the equipment appropriately, vacuum → steam heating →
A series of heat treatment operations such as leaving for a certain period of time → re-vacuum → breaking vacuum → cooling and drying are performed in the heat treatment tank 1 ′ (or 1).

The number of the spinning bobbins 23 to be heat-treated at one time in the heat treatment tanks 1 and 1 'is determined according to the number of spindles of the spinning machine 21, the yarn count, the time until the groove tube is formed, and the like. However, it is advisable to look at some extra capacity.

In the above embodiment, two heat treatment tanks 1, 1 '
However, the number of heat treatments can be increased or the heat treatment time can be lengthened by increasing the capacity of one tank or increasing the number of tanks.

Considering the cycle time of the heat treatment, if the heat treatment time is 5 to 15 minutes, the loading and unloading time of the spinning bobbin 23 can be about 1/2 to 1/5 of that.

Spinning bobbin 23 after heat treatment by steam setting process
After being sufficiently cooled and dried by breaking the vacuum with low-temperature air and ventilating the low-temperature air, it is sent to the hoisting machine 22, and is sent out according to the number of spinning bobbins 23 consumed by the hoisting machine 22. Heat treatment tanks 1,1 '
The heat insulating plate 14 is useful at this time, and functions to increase the cooling effect by blocking radiation from the wall surfaces in the heat treatment tanks 1 and 1 '.

The number of heat treatment tanks 1 and 1 'of the present invention is not limited to two or more than two tanks as in the above embodiment, while the spinning bobbin 23 is being loaded and unloaded into one tank. The present invention can be effectively applied by performing a series of heat treatments on the spinning bobbin 23 transferred in the tank.

[Effects of the Invention] The effects of the present invention are as follows.

(1). After the internal stress is released by setting the spinning bobbin by steam, cooling and drying are rapidly performed by ventilation cooling, so the shape of the spinning can be fixed as it is, improving the heat setting effect. In addition to this, automatic connection after the yarn breakage can be performed without any problem even when the winding machine is subsequently used, so that the winding effect can be improved and the operation rate of the winding machine can be improved.

(2). The spinning of the spinning bobbin is performed in a plurality of heat treatment tanks, and the spinning bobbin is transferred to another heat treatment tank while loading and unloading the spinning bobbin in one of the heat treatment tanks. Since the above-mentioned steam setting and cooling / drying of the bobbin are performed, the heat treatment time can be shortened, so that not only the work efficiency is good, but also the heat treatment and the loading of the spinning bobbin by simply moving a plurality of heat treatment tanks, Since the unloading can be performed, only one push-in and unloading device for loading and unloading the spinning bobbin is required, which reduces the number of parts, simplifies the area around the heat treatment tank, and saves installation space. No heat treatment apparatus can be provided.
