Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a composite system, in particular, a core system is reeled at the same time as a plurality of cocoon threads are reeled from a reeling tank, and the core threads and cocoon threads are intermittently closely fixed. The present invention relates to a method and apparatus for manufacturing a composite system.

[Conventional technology]

When a plurality of cocoon threads that are reeled from the reeling tide are collected to form a single thread, a core thread different from the cocoon threads is introduced into the gathering part to align the core threads and the cocoon threads. Composite yarns that can be wound by winding and methods for manufacturing the same are known.

The thread made using this method involves winding up the cocoon thread from the cocoons gathered at the bottom of the welder, guiding the core thread into it, and simultaneously passing multiple cocoon threads and the core thread into the thread threading tube of the welder. had been introduced.

The thread threading tube of this welding device is made of a circular pipe, and the plurality of cocoon threads and core threads introduced therein form a conical shape with the apex near the lower end opening of the thread threading tube made of the circular pipe. The thread entered the threading tube, and its apex was always located at approximately the same level as the mushroom. Therefore, the core thread and the plural cocoon threads are always combined in a constant state, and both are fixed in each group of threads.

[Problem that the invention seeks to solve]

The purpose of the method and apparatus of the present invention is to obtain a composite yarn in which the core yarn and the cocoon yarn do not stick together over the entire surface of the composite yarn when manufacturing the composite yarn, and both yarns stick intermittently at some points. shall be.

[Means to solve the problem]

A plurality of surfaces are placed in a reeling tank, and a circular cocoon blocking member having a predetermined radius prevents the cocoons in the thread binding from entering a predetermined range below the thread threading tube of the rotary welding device; The core thread is fed from a position close to the outer edge within the drawing stop range, and the plurality of cocoon threads and the core thread are simultaneously introduced into the thread threading tube of the weaping device, and The opening edge at the lower end is in a flat state, so that the two threads introduced into the thread threading tube constantly reciprocate within the flat opening due to the rotation of the strapping device, and are wound up while repeatedly colliding with the end of the flat opening. When the cocoon thread collides with the end of the flat opening, the colliding ends of both threads come into close contact and are fixed. A cocoon blocking member having a circular outer peripheral surface, the lower part of which is submerged in the silk reeling well and the top exposed outside the silk reeling chamber, is placed in the tank, and the center of the thread threading tube is aligned with the center of the cocoon blocking member. A core thread guide member was provided at a position inside the blocking range near the outer edge of the cocoon blocking member.

[For production]

When the cocoon yarn and core yarn introduced into the thread threading tube of the rotary welder pass through the flat opening at the open end of the thread threading tube of the rotary welding device, the thread passing through the flat opening is caused by the rotation of the thread threading tube. It moves back and forth from one end of the yarn tube to the other once per rotation of the yarn tube. During this reciprocating movement of the cocoon thread and the core thread, the end of the opening strongly contacts the thread, and the core thread and the cocoon thread are strongly integrated only in this portion due to the sericin possessed by the cocoon thread. The above-mentioned reciprocating movement of the core thread and the cocoon thread becomes much stronger at a position where the core thread is away from the center of the ili blocking member. Further, as the diameter of the 1 m blocking member is increased, the surface unwinding tension can be increased, and in conjunction with tension adjustment during feeding of the core yarn, the properties of the yarn made can be changed.

〔Example〕

Reference numeral 1 denotes a yarn binding machine, which is similar to the conventional device in that it has a small frame 3 for winding raw silk with a dry yarn device 2 at the top, a reeling tank 4 and an arrangement device 5 at the bottom, and a kennel 6 at the center. be. On the opposite side of the binding machine 1 across the work passage 7, a core yarn support stand 9 is provided on which the core yarn 8 is set.

10,. 10 is a core thread guide.

Reference numeral 11 denotes rotary welding devices, which are provided on the frame at predetermined intervals. The details are shown in Figure 2. Reference numeral 13 denotes a sliding metal fitting, which is fixed to the frame 12 with a screw 14 and supports threading threads 1!15 in a rotatable manner. The upper part of the threading tube 15 is connected to the collar 16.
It is fixed in place and has a joint ji17 at the bottom. Contact Wi
The blades 17 are rotated by a round belt 19 that is rotated by a driving unit (not shown). The opening edge on the thread introduction side at the lower end of the thread threading tube 15 is flattened to form a flat opening 27 .

The cocoon blocking member 21, which is located below the weaping machine 11 and whose lower part is immersed in the silk reeling vessel 20 of the silk reeling tank 4 and whose upper part is brought out outside the silk reeling vessel 20 and has a circular outer circumferential surface, is inserted through the thread reeling machine 11. The yarn tube 15 is provided and supported at the tip of a guide pipe 22 fixed to the frame 12, with the centers of the yarn tube 15 aligned with the centers thereof. Guide pipe 2
The front end opening 23 of No. 2 is opened at a position away from the center of the reeling cocoon removal/tension adjustment device 21. The above cocoon prevention member 2
Needless to say, the support means 1 may be not limited to the guide pipe 22 but may be any other appropriate means.

The larger the diameter of the cocoon blocking member 21, the greater the unwinding tension on the binding surface, so an appropriate one is selected taking into account the tension of the core yarn during binding.

Next, a method for manufacturing a composite system using the apparatus of the present invention will be explained.

The number of grains corresponding to the predetermined fineness is 1 in the reeling yarn 120 of the reeling tank 4.
Put in iii 24, pull out each cocoon thread 25,
It is the same as a normal binding thread in that it is inserted into the threading tube 15 of the welding device 11 and wound around the small frame 3 through the kennel 6. Since the cocoon stopper member 21 is provided so as to be located between both ends 24, the thread 124 in the binding thread is located on the outer circumferential surface 2 of the cocoon stopper member 21.
6, the cocoon thread 25 that is brought up has a conical shape, and after contacting the flat opening 27 of the thread threading tube 15, it enters the thread threading tube 15 and the top of the conical body is It is located within the thread threading tube 15 of the suture device 11. and,
The core thread 8 pulled out from the tip opening 23 of the guide vibe 22 is introduced into the conical body. The core yarn 8 is pulled out from the package, passes through guides 10, 10, and enters the reeling tank 4.
Although the core yarn is guided by the upper guide vibe 22, since the tip opening 23 of the guide vibe is located eccentrically from the center of the bottom of the conical body constituted by the cocoon yarn 25, the core yarn introduced into the thread threading tube 15 is guided by the guide vibe 22 above. 8 first entangles with the cocoon thread 25' pulled out from the cocoon 24' located near the eccentric position of the tip opening 23, and then comes into contact with other cocoon threads 25 within the thread threading tube 15. The above-mentioned entanglement occurs due to the rotation of the thread threading tube 15. In addition, since the guide vibe tip 23 is located at a position offset from the center of the cocoon prevention member 21, the core thread introduced into the flat opening 27 of the thread passing tube 15 is inserted between the tip opening 23 and the flat opening 27.
Since the core yarn 8 that connects the core yarn 7 and the core yarn 8 passes through a position deviated toward the flat opening 27 and enters the thread threading tube 15, as the thread threading tube 15 rotates, the core thread 8 and the cocoon thread 25' entangled therewith are separated. ,
25' is in a state of reciprocating within the flat opening 27. Therefore, during the reciprocating movement of the cocoon thread and the core thread, the end of the flat opening and the thread come into strong contact, and the core thread and the cocoon thread are firmly integrated only in this part, forming a fixed part 31, and the thread threading tube is While the core thread and cocoon thread are rotating and moving from one end of the flat opening 27 to the other end, the cocoon thread and the core thread passing through the flat opening 27 do not receive any force, so they are swollen and aligned and do not adhere to each other. It becomes a shaped portion 32.

Note that the cocoon filament that is reeled from the cocoon in the reeling bath has a conical outer circumference even without the blocking member, but if the number of grains is the same, with the blocking member provided, the diameter of the base of the conical body will be smaller. This increases the contact force at the flat opening 17 of the threading tube 15, and improves the adhesion between the cocoon threads and between the cocoon threads and the core thread.

〔Effect of the invention〕

According to the method and apparatus of the present invention, when reeling is performed with cocoon thread attached to the core thread, the cocoon thread attached to the core thread is intermittently firmly joined to the core thread at appropriate intervals in the length direction. The other parts can be separated from the core yarn and aligned. The thread obtained for this purpose is
Not only can the yarn be made into a highly flexible yarn that is not rigid and bends easily, but it can also be made into a yarn that can fully exhibit the properties of both a core yarn and a cocoon yarn.
