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 setting, 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 tips of the spun yarn drawn out by the air flow will not be aligned in the direction of the air flow due to the twisting torque during spinning, and therefore the spun yarn will There is a problem that automatic joining is not possible.

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. This simultaneous steam setting method involves gathering the spinning bobbins manufactured in each spinning machine into a yarn box, transporting them to a processing pot, performing steam centing, and then taking out the spinning bobbins from the processing pot. , we use a method of transporting them to the hoisting machine and attaching them one by one to the shaft of the hoisting machine.

In such processing steps for spinning bobbins, each step of taking out the spinning bobbin from the spinning machine or attaching the spinning bobbin to the winding machine is automated. However, even in these processes, a transport route is required in which a certain amount of spinning bobbins must be transported in bulk to a processing kettle, set in steam, and then transported to a winding machine and wound.

In other words, in the conventional heat treatment method for spinning bobbins, the steam setting process is independent, and there are at least five processes: ■ Spinning machine - ■ Conveying device - ■ Steam cent device - ■ Conveying device - ■ Winding machine equipment is required.

From the configuration of the device, there is a preparatory step of packing a certain amount of spinning bobbins into a yarn box for supplying the spinning bobbins to the steam setting device, supplying the yarn box to the steam setting device, spinning bobbins that have completed steam processing, That is, a series of steps such as unloading the yarn box are required, which complicates the steps and hinders the continuous processing of spinning bobbins. 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 varies depending on the type of yarn wound on the spinning bobbin, such as wool, a blend of cotton and synthetic fibers, etc. The processing temperature and time required for processing will change, but in any case, if the number of spinning bobbins processed within a unit time increases, the installation location of the conventional continuous heat treatment equipment will be at the spinning machine. Considering the restriction that the heat treatment equipment be installed between the heat treatment equipment and the hoist, the area occupied by the heat treatment equipment becomes large, resulting in the problem that the heat treatment equipment cannot be processed.

[Purpose of the invention]

The present invention was made in order to solve the problem that in the conventional heat treatment process of spinning bobbins, the steam setting process is independent and continuous processing is obstructed in that process. The object of the present invention is to provide a processing device for spinning bobbins that can steam-scent 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 is provided by a conveyor line that transports the spinning bobbins manufactured in the spinning process using a spinning machine and then transported to a winding process using a winding machine. From the middle of the process, multiple spinning bobbins depending on the capacity of the spinning machine are taken out while still being inserted into the peck stand and transferred to a heat treatment tank, where they are vacuum-steam heated, left for a certain period of time, and then vacuumed again. It is constructed by installing a heat treatment tank that enables a series of heat treatments such as vacuum breaking, and after the heat treatment is completed in the heat treatment tank, the spinning bobbin is taken out and transferred again to the conveyor line for transfer. According to this device, the spinning bobbin inserted into the peckstand during heat treatment is handled with the spinning bobbin placed upright on the peckstand, so that the surface of the spinning bobbin is not damaged due to contact with the iron during heat treatment. There is no chance of the thread becoming dirty or disordered.
In addition, complete heat treatment can be performed during transfer from the spinning machine to the winding machine without requiring any manual labor.

(Example) The present invention will be described in detail below with reference to the drawings. In each example, the same parts are indicated by the same part numbers, and FIG. 1 shows an implementation of the spinning bobbin heat treatment apparatus of the present invention.

The heat treatment tank 1 constituting this heat treatment apparatus is connected to a conveyor line 12.12 that conveys the spinning bobbin 5 produced in the spinning process by the spinning machine 6 shown in FIG. 1 to the winding process by the winding machine 7.
Inside this heat treatment tank 1, a guide rail 11 for holding a beta stand 1'0 for inserting a spinning bobbin 5, and a peck stand 10 are moved. A conveyor 3 shown in FIG. 2 is provided for this purpose and is hermetically sealed by a horizontally sliding door 2.2'.

Next, the spinning bobbin 5, which has been made full and doffed in the spinning process by the spinning frame 6, is sent from the spinning frame 6 to the heat treatment tank 1 by a conveyor line 12 with a guide rail 11 shown in FIG. However, the pec stand 10 that has been sent to position A in FIG. It is pushed along the guide rail 11.

By repeating this movement, the heat treatment tank 1 becomes full with the peck stand 10 in which the full spinning bobbin 5 is inserted, and the door 2
, 2' are tightened, by appropriately operating the vacuum pump 8, steam generator 9, etc. connected to this heat treatment tank 1, a series of steps such as vacuum-steam heating, leaving for a certain period of time, re-vacuum, and vacuum-breaking are performed. The following heat treatment operations are performed within this heat treatment tank 1.

Next, when this heat treatment is completed, the door 2.2' is opened, the conveyor 3 is moved, and the pecstands 10 are pushed out one by one to the exit guide 14, the direction is changed by the pusher cylinder 17, and the extrusion cylinder 18 moves the peckstands 10 to the conveyor line 12. ' and is sent to the hoisting machine 7, where it enters the hoisting process.

Furthermore, as soon as the conveyor 3 moves, the insertion of a new spinning bobbin 5 begins, and when the heat treatment tank 1 is full, the door 2.2' is closed and the next heat treatment begins.

Here, the spinning bobbin 5 is heat-treated at one time in the heat treatment tank 1.
The number of spinning machines 6 is determined according to the number of spindles of the spinning machine 6, the yarn count, and the capacity of the spinning machine 6, such as the time required to complete the spinning machine, but in any case, some allowance should be made for the capacity. This is desirable.

Note that the device for transferring the spinning bobbin 5 from the conveyor line 12, 12' to the heat treatment tank 1 in the heat treatment device according to the present invention is not limited to that shown in the above-mentioned embodiment 1, but is As in Embodiment 2 shown in the side cross-sectional view of FIG. The spinning bobbin 5 inserted into the peck stand 10 is once transferred from the conveyor line 12 into the heat treatment tank 1, where it is subjected to a predetermined heat treatment, and then transferred to the conveyor line 12' again. It is important to send them to

〔Effect of the invention〕

As explained above, the spinning bobbin heat treatment apparatus of the present invention is capable of treating spinning bobbins produced in the spinning process while being inserted into a peck stand and conveyed on a conveyor line.
From the transfer conveyor line, the peck stand is transferred to a heat treatment tank, where it is subjected to prescribed heat treatment, and after the heat treatment is completed, the spinning bobbin is transferred to the conveyor line again and transported to the winding machine. As a result, since the spinning bobbin is handled while still being inserted into the peck stand, there is no fear of damage to the outer circumferential surface, and the transfer and heat treatment of the spinning bobbin can be easily automated. Although it depends on the number of spinning bobbins to be heat treated, it does not require a particularly large floor space and can be easily installed between the spinning machine and the winding machine, so the length of the conveyor line from the spinning machine to the winding machine can be reduced. It does not need to be long, eliminates the need for yarn boxes and transportation carts, etc. required for conventional heat treatment of spinning bobbins, and eliminates the need to install a heat treatment room in a separate location, increasing flexibility in factory layout. etc. The effects are enormous.
