Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a spinning bobbin in which bobbin yarn wound by a spinning machine, that is, a spinning bobbin, is subjected to heat treatment, that is, steam set, while being transported to a winding machine. The present invention relates to heat treatment equipment.

[Prior art]

It is necessary to wind the spun yarn spun from raw cotton, raw wool, sliver of synthetic fibers, etc. onto a bobbin, and wind this bobbin yarn, that is, the spun bobbin as a unit, onto corn cheese or parallel cheese using a winding machine. However, in this process, it is necessary to join the spun yarns when a new spinning bobbin is supplied to the winding machine. However, if the spun yarn is not heat-treated, that is, steam set, at this point, the tip of the spun yarn drawn out by the airflow will not be aligned in the direction of the airflow due to the twisting torque during spinning, and the spinning yarn will not be aligned with the direction of the airflow. There is a problem in that the threads cannot be joined automatically.

Therefore, steam setting is performed before the spun bobbin is fed to the winding machine.

Conventionally, the above-mentioned spinning bobbins were randomly placed into a predetermined box called a yarn box, and then assembled into dozens of boxes, which were then placed in a processing kettle and steamed all at once. It is set. In this simultaneous steam setting method, the spinning bobbins produced in each spinning machine are assembled into a yarn box, transported to a processing pot, where steam setting is performed, and the spinning bobbins are taken out from the processing pot. We use a method in which they are transported to the hoisting machine and attached to the shaft of the hoisting machine one by one.

In this spinning bobbin processing process,
Each process, such as removing the spinning bobbin from the spinning machine or attaching the spinning bobbin to the winding machine, is automated. However, even in these processes, a transportation route is required in which a certain amount of spinning bobbins must be transported in bulk to a processing kettle, set in steam, and transported to a winding machine for winding. .

In other words, in the conventional spinning bobbin heat treatment method, the steam setting process is independent, so at least five devices are required: spinning machine → conveyance device → steam setting device → conveyance device → winding machine. .

From the configuration of the device, there is a preparation step for packing a certain amount of spinning bobbins into a yarn box for supplying spinning bobbins to a steam setting device, a step of supplying the yarn box to a steam setting device,
This requires a series of steps such as transporting the spinning bobbin, that is, the yarn box, which has been steam-treated, which complicates the process and poses an obstacle to the continuous processing of the spinning bobbin. The biggest problem causing this failure is that the steam setting process is an independent process.

On the other hand, among the various conventional heat treatment methods for spinning bobbins, the required processing time for vacuum heat treatment depends on the type of yarn wound on the spinning bobbin, such as wool, a blend of cotton and synthetic fibers, etc. As a result, the processing temperature and time required for processing will change somewhat, but in any case, if the number of spinning bobbins processed within a unit time increases,
With conventional continuous heat treatment equipment, considering the restriction that it must be installed between the spinning machine and the winding machine, the heat treatment equipment occupies a large area, making it impossible to process. It comes.

[Purpose of the invention]

The present invention was made in order to solve the problem that the steam setting process is independent in the conventional heat treatment process of spinning bobbins, which hinders continuous processing in that process. The object of the present invention is to provide a processing device for spinning bobbins that can steam-set a plurality of spinning bobbins one by one in a conveyor line for conveyance and transport them to a winding machine or a suitable location, and that does not take up much space for installation. This is what I did.

[Structure of the invention]

In order to achieve the above object, the spinning bobbin heat treatment apparatus of the present invention includes a plurality of heat treatment tanks arranged side by side in the horizontal direction between a spinning machine and a winding machine, and provided movably in the horizontal direction. Each heat treatment tank has an inlet and an outlet for carrying in spinning bobbins from the spinning machine in the vertical direction, and heat treatment is performed using a vacuum pump and a steam generator at the horizontal movement position of the heat treatment tank, and the spinning bobbin is carried in. and an unloading position, which consists of a spinning bobbin heat treatment device that carries spinning bobbins into and out of the heat treatment tank, and connects multiple heat treatment tanks in a horizontally interlocking manner. , all the heat treatment tanks are moved horizontally at the same time, and the vacuum pump and steam generator necessary for heat treatment of the spinning bobbin are installed near the connected heat treatment tanks. Consists of heat treatment equipment. Therefore, in the middle of the conveyor line that transports the full spinning bobbins manufactured in the spinning process using a spinning machine to the winding process using a winding machine, a plurality of spinning bobbins are installed according to the capacity of the spinning machine. The spinning bobbins are removed from the conveyor line while still attached to the peck stands, transferred to a heat treatment tank, and then vacuumed →
Multiple heat treatment tanks are connected to enable a series of heat treatments such as steam heating → standing for a certain period of time → re-vacuum → vacuum breaking, etc., and spinning bobbins are carried in and out of one of the heat treatment tanks. The system is characterized in that it is possible to perform the above-mentioned series of heat treatments on spinning bobbins transferred to other tanks while the spinning bobbins are being transferred to other tanks. It is preferable that the spinning bobbin can be moved alternately and simultaneously between the loading and unloading positions of the spinning bobbins and the heat treatment.In this case, there is only one loading and unloading location for the spinning bobbins for multiple heat treatment tanks. This means that the number of parts for the loading and unloading equipment will be reduced.

Furthermore, in the heat treatment apparatus of the present invention, the vacuum pump, steam generator, etc. necessary for heat treatment of the spinning bobbin are installed above the plurality of connected heat treatment tanks, which simplifies the surroundings of the heat treatment apparatus. This is a desirable configuration for

The heat treatment apparatus of the present invention having the above configuration takes out the spinning bobbin after the heat treatment is completed in the heat treatment tank, and
According to this device, the spinning bobbin inserted into the peck stand during heat treatment is handled while it is still standing on the peck stand, so that it is not exposed to other objects during the heat treatment. There is no staining or disturbance of the yarn on the surface of the spinning bobbin due to contact with the spinning bobbin, and complete heat treatment can be performed during transfer from the spinning machine to the winding machine without requiring any manual labor.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan cross-sectional view of an embodiment of the spinning bobbin heat treatment apparatus of the present invention, and FIG. 2 is a front view in the - direction of FIG. 1. 3 are enlarged sectional views of the peck stand and guide rail of FIG. 1.

The heat treatment apparatus constituting this embodiment is one in which a plurality of heat treatment tanks 1, 1' are connected side by side as in this embodiment. It is installed on Colo 4.

That is, the entrance side conveyor 5 and the exit side conveyor 9 are located in the middle of a conveyor line in which spinning bobbins 23 manufactured in the spinning process by the spinning machine 21 shown in FIG. 1 are conveyed to the winding process by the winding machine 22.
As shown in Fig. 3, two heat treatment tanks 1 and 1' are connected between the heat treatment tanks 1 and 1', which can be transferred and heat-treated while being inserted into the peck stand 30.
While the spinning bobbins 23 are being carried into and out of one of the tanks 1', a series of heat treatments are performed on the spinning bobbins 23 that have been transferred to the other tanks.

Next, to explain the operation of this heat treatment equipment, assuming that the two heat treatment tanks 1 and 1' are at the positions of arrows A and B in Fig. 1, the steam set is in the heat treatment tank 1 at position A. The process is carried out according to a program, and in the heat treatment tank 1' located at position B, the spinning bobbins 23 that have been steam-set are pushed out in rows of three by the action of the push cylinder 7 from the conveyor 5 on the entrance side, and then sent to the exit chute. 8 to the exit side conveyor 9.

If the pushing cylinder 7 on the inlet side is stopped when the spinning bobbins 23, which have been steam-set, come out of the heat treatment tank 1', the heat treatment tank 1' is filled with untreated spinning bobbins 23.

When the steam setting in the heat treatment tank 1 at position A is completed, both heat treatment tanks 1 and 1' are driven by the cylinder 10 in FIG. 2 and simultaneously move to the positions indicated by arrows B and C, respectively.

Then, from the heat treatment tank 1 that has come to position B, the spinning bobbin 23 is pushed by a new spinning bobbin 23 by the pushing cylinder 7 on the inlet side and sent out from the outlet side chute 8 to the outlet side conveyor 9 in the same way as described above, and is then heat treated. The tank 1 is filled with new spinning bobbins 23.

Next, the door 2' of the heat treatment tank 1' sent to the C position is closed by the cylinder 11, and the steam setting process begins in a series of vacuum → steam heating → standing for a certain period of time → re-vacuum → vacuum breaking.

Next, to explain the movement of the spinning bobbin 23, the spinning bobbin 23, which has become full and doffed in the spinning process by the spinning machine 21, is sent from the spinning machine 21 to the heat treatment tanks 1 and 1'. , the pusher cylinder 6 changes direction while being inserted into the peck stand 30 that has been sent to the position shown in Figure 1 and is pushed out to the positions shown by F, G, and H, and the pusher cylinder 7 works to move the heat treatment tank 1' (or 1).

By repeating this movement, the heat treatment tank 1' (or 1) becomes full with the peck stand 30 in which the full spinning bobbin 23 is inserted, moves to position C (or position A), and closes the door 2' (or 2). After the heat treatment tank 1' (or 1) is closed, the equipment necessary for heat treatment, such as the vacuum pump 12 and steam generator 13, which are connected to the heat treatment tank 1' (or 1) and installed at the top of the heat treatment tank 1, 1', are connected as appropriate. By this operation, a series of heat treatment operations such as vacuum → steam heating → standing for a certain period of time → re-vacuum → vacuum breaking are performed in the heat treatment tank 1' (or 1).

Next, the structure of the heat treatment apparatus according to the present invention will be explained. Considering the arrangement relationship between the spinning machine 21 and the winding machine 22 in the spinning factory, considering the purpose of the present invention, the full spinning bobbin 23 Since the present invention was made to eliminate the inconvenience of transporting the spinning machine around the factory, it is assumed that the spinning machine 21 and the winding machine 22 are installed close to each other on the line. This heat treatment device should be placed in an intermediate position, and therefore requires an extremely small area to occupy.

Therefore, in order to make the area around the heat treatment tanks 1 and 1' as simple as possible, the idea was to move the two heat treatment tanks 1 and 1' at the same time, and to move the vacuum pump 12, steam generator 13, etc. It is installed at the upper part of the heat treatment tank 1, 1'.

The number of spinning bobbins 23 that are heat-treated at one time in the heat treatment tanks 1 and 1' is determined depending on the number of spindles of the spinning machine 21, the yarn count, and the time period until the tubes are full. However, it is desirable to have some margin of ability.

In the above embodiment, the case of two heat treatment tanks 1 and 1' was explained, but the number of heat treatment tanks can be increased by increasing the storage capacity of one tank or by increasing the number of tanks, or the heat treatment time can be lengthened. is possible.

Also, considering the heat treatment cycle time, if the heat treatment time is 5 to 15 minutes, the spinning bobbin 2
Since the loading and unloading time in step 3 can be done in about 1/2 to 1/5 of that time, it is better to perform the heat treatment in the fixed position without moving the heat treatment tanks 1 and 1', and then carry in and unload. It is possible to increase the throughput of the equipment as a whole, but in order to do so, it is necessary to
Multiple take-out devices will be required, and even if the spinning bobbins 23 that have been heat-treated are taken out all at once, the winding machine 22 will not have the capacity to accommodate them.
Since the pool has to be created somewhere else and a suitable location cannot be found, as explained in the present invention, even if the processing power is reduced to some extent,
It is more rational to carry out heat treatment alternately in each of the two heat treatment tanks 1 (or 1') and use the heat treatment tank 1 (or 1') carried in and taken out as a pool for the spinning bobbins 23 that have been heat treated. .

Note that even when the number of heat treatment tanks 1, 1' of the present invention is more than two layers as in the above embodiment, while the spinning bobbins 23 are being carried into and out of one tank, Spinning bobbin 23 transferred into the tank
The present invention can be effectively applied by performing a series of heat treatments.

〔Effect of the invention〕

As explained above, in the heat treatment apparatus of the present invention, the spinning bobbin inserted into the peck stand is handled with the peck stand erected during the heat treatment, so there is no dirt or disturbance on the surface of the spinning bobbin. This has the effect of allowing complete and good heat treatment and improving the product yield.

Further, in the heat treatment apparatus of the present invention, a plurality of heat treatment tanks can be moved simultaneously, and while a plurality of spinning bobbins are being carried in and out of one tank, a series of heat treatment of spinning bobbins in other tanks is carried out. By doing this, only one push-in and take-out device is required for loading and unloading the spinning bobbin, which reduces the number of parts, and also allows the vacuum pump and steam generator for heat treatment to be moved to the upper part of the heat treatment tank. By installing the heat treatment tank, the surroundings of the heat treatment tank can be simplified, and a heat treatment apparatus that does not take up much space can be provided.
