Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a spinning bobbin in which a bobbin thread wound by a spinning machine, that is, a spinning bobbin, is heat-treated, that is, steam-set while being transported to a winding machine. The present invention relates to a heat treatment method.

[Conventional technology]

It is necessary to wind a spun yarn spun from raw cotton, raw wool, a sliver of synthetic fiber, etc. onto a bobbin, and to wind this bobbin yarn, that is, a spun bobbin, into corn cheese or parallel cheese using a hoist. However, in this step, spun yarn must be joined when a new spinning bobbin is supplied to the hoisting machine. However, at this point, if the spun yarn is not heat-treated, that is, steam-set, the tip of the spun yarn drawn by the air flow is not aligned in the direction of the air flow due to the twisting torque during spinning, and thus the spun yarn is There is a problem that the automatic joining of is not possible.

Therefore, before the spinning bobbin is supplied to the hoist, steam is set.

Conventionally, the spinning bobbin as described above is randomly loaded with bobbins in a predetermined box called a tube thread box and is assembled into several dozen boxes as a unit of the tube thread box. I have set. In this simultaneous steam setting method, the spinning bobbins produced in each spinning machine are put together in a tube yarn box, transported to a place where there is a treatment kettle and steam set, and the spinning bobbin is taken out from the treatment kettle. The method is that they are carried to the hoisting machine and attached one by one to the shaft of the hoisting machine.

In the processing step of such a spinning bobbin, the steps of taking out the spinning bobbin from the spinning machine or attaching the spinning bobbin to the winding machine are automated. However, even in these processes, a transport route is required in which a certain amount of fine spinning bobbins are collectively transported to the processing kettle, steam-set, and then transported to the hoist and wound up. .

In other words, the conventional spinning bobbin heat treatment method requires at least five devices, namely, a spinning machine, a carrying device, a steam setting device, a carrying device, and a hoisting machine because the steam setting process is independent. .

From the configuration of the device, a preparatory step of packing a fixed amount of bobbin for supplying a spinning bobbin to a steam setting device in a yarn thread box, supplying to the steam setting device of the yarn thread box, a spinning bobbin that has completed steam treatment, In other words, a series of processes such as unloading of the tubular yarn box is required, which complicates the process and hinders continuous processing of the spinning bobbin. The biggest problem that causes this obstacle is that the steam setting process is an independent process.

On the other hand, among various conventional heat treatment methods for spinning bobbins, the required treatment time for vacuum heat treatment depends on the type of yarn wound on the spinning bobbin, for example, wool, a blend of cotton and synthetic fiber, or the like. However, if the number of spinning bobbins to be processed within a unit time increases in any case, in the conventional continuous heat treatment equipment, the installation location is the spinning machine. Considering the restriction that it is installed between the machine and the hoisting machine, the area occupied by the heat treatment apparatus becomes large, and the problem of inability to process occurs.

[Problems to be Solved by the Invention]

The present invention was made in order to solve the problem that the steam setting step is independent in the heat treatment step of the conventional spinning bobbin, and continuous processing is hindered in the step, and is produced by a spinning machine. One of the problems to be solved is to provide a spinning bobbin processing method in which a plurality of spinning bobbins can be steam-set in the middle of a conveyor line for transporting them, can be transported to a hoisting machine, and can be installed in a small space. Is.

[Means for Solving the Problems]

As a means for solving the above problems, a method for heat treating a spinning bobbin according to the present invention is provided with a conveyor line between a spinning machine and a hoisting machine, and at least two heat treating tanks are provided in the middle of the conveyor line. Fixedly arranged in parallel, each heat treatment tank has open and close doors on the inlet and outlet sides of the spinning bobbin, each heat treatment tank is connected to a vacuum pump and steam generator, and the door of the heat treatment tank is closed. The heat treatment method of the spinning bobbin is such that the door of another heat treatment tank is opened and the spinning bobbin is carried in and out while the heat treatment of the spinning bobbin is performed by the steam from the steam heat generator.

In other words, a complete steam-set heat treatment can be performed without any manpower required during the transportation of the spinning bobbin from the spinning machine to the hoisting machine.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
1 is a plan sectional view of an embodiment of a heat treatment apparatus for a spinning bobbin according to the present invention, FIG. 2 is a front view in the direction I--I of FIG. 1, and FIG. 3 is a peck stand and a guide rail of FIG. It is an expanded sectional view.

The heat treatment apparatus used in the embodiment of the present invention is at least 1
Pair, eg two independent heat treatment tanks as in this example
These heat treatment devices are installed side by side next to 1,1 '.
1, 1'is provided in the middle of the conveyor line between the spinning machine 21 and the hoisting machine 22 and heat-treated.

That is, the spinning bobbin 23 manufactured in the spinning process by the spinning machine 21 shown in FIG. 1 is conveyed to the hoisting process by the hoisting machine 22 in the middle of the conveyor line. As shown in FIG. 3, two heat treatment tanks 1, 1 ′ that can be transferred and heat-treated while being attached to the peck stand 30 are connected between the two heat treatment tanks. While the spinning bobbin 23 is carried in and out of one tank, a series of steam sets of the spinning bobbin 23 transferred into another tank are heat-treated.

The spinning bobbin 23 coming out of the spinning machine 21 has two heat treatment tanks 1.
In order to sort and send to either 1 ', for example, Japanese Patent Application No. 62-1-6360 already filed by the applicant (Japanese Patent Laid-Open No. 63-275
728) and Jpn. App. No. 62-8635 (Jun. 4-3033).

That is, the swing type transfer table in the former case and the transfer conveyor in the latter case are used.

Next, the operation of the heat treatment apparatus will be described. One of the two heat treatment tanks 1 and 1 ′ is currently steam-set, and the other heat treatment tank 1 is a spinning bobbin 23. Comes from the inlet side conveyor 5, is aligned with the pusher cylinder 6, and is pushed into the pusher cylinder 7 by one row at a time, and at the same time, three steam-set spinning bobbins are fed from the outlet side chute 8 to the outlet side conveyor. Sent to 9.

By repeating such pushing and feeding operations, the steam-set spinning bobbin 23 in the heat treatment tank 1 ′ completely replaces the untreated spinning bobbin 23.

That is, when all the spinning bobbins 23 that have completed steam setting have exited the heat treatment tank 1 ', the pushing cylinder 7 on the inlet side
When the heating is stopped, the untreated spinning bobbin remains in the heat treatment tank 1 '.
23 is full.

Eventually, when the steam setting in the heat treatment tank 1 is completed, the doors 2 at the inlet and outlet of the heat treatment tank 1 are moved by the cylinder 10 on the rollers 4 in FIG.

Therefore, from the opened heat treatment tank 1, the processed fine spinning bobbin 23 is pushed from the exit side chute 8 to the exit side conveyor 9 by being pushed to the new fine spinning bobbin 23 by the pushing cylinder 7 on the entrance side as described above. By this repeated operation, the heat treatment tank 1 is filled with a new spinning bobbin 23.

Next, in the heat treatment tank 1 ', each door 2'moved to the inlet / outlet is brought into close contact with the flange of the inlet / outlet of the heat treatment tank 1'by the cylinder 11 and sealed, and then the vacuum → steam heating →
A series of steam setting process of leaving for a certain period of time, re-vacuum, and breaking vacuum is started.

Next, the movement of the spinning bobbin 23 will be described.
The spinning bobbin 23, which has been filled up in the spinning process by the 21 and is fried, is sent from the spinning machine 21 to the heat treatment tanks 1, 1 ', but by the pusher cylinder 6 while being attached to the peck stand 30. When the direction is changed to push out to the position where three pieces are aligned, the pushing cylinder 7 works to push the inside of 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, and the door 2' (or 2) is tightened by the cylinder 10 and then the heat treatment is performed. Vacuum pump 1 connected to tank 1 '(or 1) and installed on top of this heat treatment tank 1, 1'
2. By properly operating the equipment necessary for heat treatment such as steam generator 13, a series of heat treatment operations such as vacuum → steam heating → leaving for a certain time → re-vacuum → vacuum breaking can be performed in heat treatment tank 1 '(or 1) Done in.

Next, an apparatus for carrying out the heat treatment method according to the present invention will be described. Considering the positional relationship between the spinning machine 21 and the hoisting machine 22 in the spinning factory, in consideration of the purpose of the present invention, a full-scale spinning machine is considered. Since the present invention has been made to eliminate the inconvenience of transporting the spinning bobbin 23 in the factory, the spinning machine 21 and the hoisting machine 22 are installed close to each other on the line. Considering that, this heat treatment apparatus should be placed at the intermediate position thereof, which requires that the occupied area thereof be extremely small.

Therefore, in order to make the surroundings of the heat treatment tanks 1 and 1'as simple as possible, it was considered to install the two heat treatment tanks 1 and 1'in two rows, and to install the vacuum pump 12 and the steam generator. It is to install 13 etc. above the heat treatment tanks 1, 1 '.

Furthermore, if there are severe restrictions on the width of the heat treatment equipment,
The doors 2 and 2'of the heat treatment tanks 1 and 1'can also be moved up and down to open and close.

In addition, the vacuum pump 12 and the steam generator 13 are connected to each heat treatment tank 1, 1 '.
It is not necessary to install it in each of the above, and it is possible to share it with a plurality of heat treatment tanks.

The number of 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, and the time until fullness, etc. However, it is desirable to have some margin of ability.

In the above embodiment, the case of two heat treatment tanks 1 and 1'has been described, but the number of heat treatment tanks is increased by increasing the capacity of one tank or the number of tanks, or the heat treatment time is lengthened. It is possible to

Considering the heat treatment cycle time, if the heat treatment time is 5 to 15 minutes, the loading and unloading time of the spinning bobbin 23 can be 1/2 to 1/5 of that time.
The heat treatment tanks 1 and 1 ′ are fixed and heat treatments are performed at fixed positions respectively. At this time, by shifting the processing programs of the two tanks and operating them in parallel, it is possible to increase the processing amount of the entire apparatus. However, in this case, a spinning bobbin loading and unloading device is required for each tank, but the processing capacity is increased. In addition, even if the spinning bobbin 23 that has been heat-treated is taken out at all, the hoisting machine 22 does not have the capacity to accommodate it, and if a pool must be created somewhere else, the processing capacity will be somewhat reduced. Even one heat treatment tank 1
It is also possible to use the heat treatment tank 1 (or 1 ') in which heat treatment is alternately carried out (or 1') and carried in and carried out as a pool of the spinning bobbin 23 of which the heat treatment has been completed.

Even if the number of heat treatment tanks 1 and 1'used in the present invention is more than one pair and two tanks as in the above embodiment, the spinning bobbin 23 should be loaded into and unloaded from one tank. The present invention can be effectively applied by performing a series of heat treatments on the spinning bobbin 23 transferred to another tank while the tank is in operation.

〔The invention's effect〕

(1) The heat treatment apparatus used in the present invention is at least 2
Since the individual heat treatment tanks are fixed in parallel and the spinning bobbin is carried in and out of one tank, a series of heat treatments of the spinning bobbins in the other tanks are performed. Well, the length of the bath can be reduced as compared with the conventional case where only one heat treatment bath is used.

That is, since the heat treatment tank is carrying in and out the spinning bobbin, is performing heat treatment, and the heat treatment tank is always operating effectively without any break, the productivity can be increased.

(2) Since it is possible to alternately operate two or more heat treatment tanks provided in parallel, even if one tank fails, the heat treatment can be performed by the other tank, and the work cost can be reduced.

(3) Heat treatment tanks and spinning bobbins can be carried in and out simply by installing and fixing the heat treatment tanks and moving the doors, so there is less equipment and power for movement, and there are less failures due to movement. This has the advantage that no work time is lost due to movement.
