"Prior art and its problems" FIG. 11 shows a conventional example of an extruder for manufacturing filament bodies. Cooling water tank C
The basic configuration is such that each winder D winds up the winder after cooling it by contacting the cooling water inside.

By the way, when the extruder starts operating,
It is necessary to guide the filament B, which is in a high temperature and soft state immediately after extrusion, to the winder D, and this work is carried out according to the following procedure.

(i) Wrap the tip of the stainless steel guide cable E around the winder D, and
guide cable E along the route to be run.
As shown in FIG. 11, a ring F for connecting the filament B is attached to the proximal end (end on the side of the extruder A) of the guide cable E.

(ii) Operate the extruder A to extrude the filament B, connect the tip of the extruded filament B to the ring F, and then operate the winder A to wind the guide cable E. take it and go
Following the guide cable E, the filament body B is wound up.

However, the above operation (ii) requires skill because it is necessary to quickly handle and attach the filament B, which is hot and soft immediately after extrusion, to the ring F. Furthermore, even if an expert is skilled, there is a limit to the number of filaments B that one person can handle. The problem is that it requires a number of personnel.

The present invention was proposed in view of the above circumstances, and allows the winding machine to automatically wind up the filament extruded from the die, thereby making it possible to operate with fewer personnel. The purpose of this invention is to provide an extruder with a high degree of flexibility.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides a cooling water tank between an extruder and a winder, and a linear body between the cooling water tank and the winder. A conveyance means is provided which rotates at a higher speed than the extrusion speed of the extruder while holding the extruder, and is allowed to slip between the extruder and the filament. This configuration is composed of a first and a second conveyance section.

"Function" By the above means, the filamentous body immediately after extrusion can be immediately cooled and hardened, and the cured filamentous body is held between rollers and a constant tension is applied while slipping, and furthermore, a certain tension is applied to the hardened filamentous body while the roller is being held between the rollers. With this, the filament can be pushed out towards the winder. Furthermore, since the first and second conveyance sections are in continuous contact, the surface of the filament is less likely to be damaged.

This winding device 7 winds up the filament 2 while rotating a winding drum 26 on which the filament 2 is wound around a shaft 27. A structure is adopted in which the filamentous body 2 is wound around a plurality of metal rods 28 which are arranged parallel to the axis 27 at positions spaced apart in the radial direction and combined into a frame shape, and

are spaced apart from each other, and furthermore, the variable speed motor 20
is adjusted so that the conveyor belt 13 is run at a speed higher than the expected extrusion speed.

(ii) When the extruder main body 1 is operated to extrude a plurality of filament bodies 2 at the same time, the extruded filament bodies 2
is guided by the Gaits pipe 25 and enters the cooling water tank 3.
The material is sent to the storage device, where it is cooled and hardened, and then taken into the transport mechanism 4 and sent out toward the winding device 7. Then, the conveyance mechanism 4 pulls the filament 2 while slipping it against the conveyance belt 13 and the pressure roller 16, and maintains the tension of the filament 2 between it and the extruder main body 1 constant. .

(iii) The filamentous body 2 sent out from the transport mechanism 4
is guided by the guide pipe 25 and fed into the traverse pipe 34 as shown in FIG.
It moves inside the traverse pipe 34.

(iv) As the filament 2 moves inside the traverse pipe 34, the sensor 39 is activated and a detection signal is output.

(v) After a certain period of time has elapsed since the output of the detection signal, actuate the air cylinder 31 to clamp the vicinity of the tip of the filamentary body 29 between the clamping members 29 and 32, and release the stopper 40; After that, the striatum 2 is

wind it up.

Note that the configuration of the conveyance mechanism is not limited to the one embodiment described above, and the belt may be omitted and the linear body may be directly held between the pair of rollers. Furthermore, by adjusting the material or surface roughness of the roller or belt, it is possible to set the frictional force between these and the filament to an appropriate value.

"Effects of the Invention" As is clear from the above description, the present invention provides a cooling water tank between an extruder and a winder, and a linear body between the cooling water tank and the winder. Since the rollers are provided to clamp and rotate at a higher speed than the extrusion speed of the extruder and to allow slip between the filament and the filament,
It has the following effects.

(a) Since the striated body is picked up immediately after extrusion by a conveying mechanism that is capable of slipping against the striated body, by adjusting the degree of slipping of the first and second conveying sections, A constant tension can be applied to the striatum. Further, thermal shrinkage due to cooling after extrusion can be easily absorbed by the slip of the conveying mechanism.

(b) The extruded filament can be immediately cooled and sent out in a stable state with no heat shrinkage and a hardened surface. In addition, since the first and second conveying sections are in continuous contact with the striatum and the surface of the striatum is hardened by cooling, discontinuous scratches etc. may occur on the surface of the striatum. It never occurs. Furthermore, since the conveying mechanism comes into contact with the cooled filament, the conveying part does not require special heat resistance, and therefore the material can be selected to obtain the required surface roughness or hardness. The range is wide.

(c) Due to the synergistic effect of (a) and (b) above, it becomes possible to automatically guide the extruded filament to the winding mechanism, and the operation of the extruder becomes labor-saving.
