Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a configuration diagram of a knitted resin manufacturing apparatus according to an embodiment of the present invention, and FIG. 2 is a top view of a cooling water tank of the knitted resin manufacturing apparatus.
The apparatus for producing a knitted resin according to the present embodiment includes an extruder 20 that extrudes molten resin, a resin pool 30 that receives the molten resin extruded from the extruder 20 and causes the molten resin to flow down from a large number of holes in the bottom surface 31 into a thread shape. A cooling water tank 40 for storing the cooling water, and a take-up machine 50 for pulling down the knitted resin 12 formed by cooling the thread-shaped molten resin (hereinafter referred to as thread-shaped molten resin) 11 flowing down from the resin pool 30 with the cooling water. .

The thread-shaped molten resin 11 is formed when it flows down from the hole in the bottom surface 31 of the resin pool 30.
A take-up machine 50 is disposed in the cooling water tank 40. The knitted resin 12 formed by cooling the filamentary molten resin 11 with cooling water is taken up by the take-up machine 50 to the bottom plate 40e side of the cooling water tank 40, and after passing through the take-up machine 50, the pull-up arranged in the cooling water tank 40 is performed. While being cooled in the cooling water, the plurality of conveying rollers 42 as members are pulled up obliquely upward and conveyed outside the cooling water tank 40.

  The extruder 20 melts and kneads the thermoplastic resin at a predetermined temperature to obtain a molten resin, and extrudes the molten resin to the resin pool 30 at a predetermined extrusion speed. Here, as the thermoplastic resin, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polytetrafluoroethylene, acrylonitrile butadiene styrene resin or the like may be used alone or in combination. The thermoplastic resin used as a raw material can be reused from used and recovered packaging containers and agricultural vinyl.

The cooling water tank 40 is a rectangular parallelepiped whose upper surface is opened, and includes a first side wall 40a, a second side wall 40b, a third side wall 40c, a fourth side wall 40d, and a bottom plate 40e. In this embodiment, the inner dimensions are: depth D ₁ (distance between the second side wall 40b and the third side wall 40c) = 2.1 m, width W ₁ (distance between the first side wall 40a and the fourth side wall 40d) = 6 m (See FIG. 2).
The cooling water tank 40 has a cooling water inlet 130 and a cooling water outlet 140. The water injection port 130 is provided on the lower side, and the drain port 140 is provided on the upper side. When the knitted resin 12 is manufactured, cooling water (such as room temperature well water or tap water) is continuously poured into the cooling water tank 40 from the water inlet 130, and the cooling water reaching a predetermined water level or higher is continuously supplied from the drain outlet 140. Drained. Although the temperature of the cooling water poured from the water inlet 130 varies depending on the season, it is generally 16 ° C to 23 ° C.

The cooling water tank 40 has a first area A and a second area B that are partitioned in the horizontal direction by the partition member 60. The first area A is narrower than the second area B.
The partition member 60 that partitions the first region A and the second region B is a rectangular plate member having a thickness of about 5 cm. The width _{W 2} of the partition member 60 is substantially equal to the depth _{D 1} of the cooling water bath 40 (see FIG. 2) are in contact without any gap between both side surfaces and the second side wall 40b, and the third side wall 40c of the partition member 60. The upper end 60b of the partition member 60 is located at or slightly above the water surface 41, and the lower end 60a of the partition member 60 is located in the range of about 40% to 60% of the water depth. In the present embodiment, the position of the lower end 60a of the partition member 60 is set to a depth of about 180 cm with respect to a depth of 350 cm. The positions of the lower end 50a of the take-up machine 50 and the lower end 60a of the partition member 60 are substantially the same. In this way, the first region A and the second region can be obtained without disturbing the conveyance of the knitted resin 12 by aligning the lower ends 50a and 60a of the take-up machine 50 and the partition member 60 and sufficiently separating them from the bottom plate 40e of the cooling water tank 40. B can be formed.
The first region A is a region surrounded by the partition member 60 and the substantially upper half of the first side wall 40a of the cooling water tank 40, the second side wall 40b adjacent to the first side wall 40a and a part of the third side wall 40c. It is. The take-up machine 50 is disposed in the first area A, and the resin pool 30 is located immediately above the first area A.
The second region B includes a substantially upper half of the fourth side surface 40d facing the first side surface 40a of the cooling water tank 40, a part of the second side surface 40b and the third side surface 40c, and the partition member 60. It is an enclosed area. In the second region B, a plurality of conveying rollers 42 that are lifting members are arranged. The knitting resin 12 that has passed through the take-up machine 50 is pulled upward obliquely while being cooled in the cooling water by the conveying roller 42 and is conveyed outside the cooling water tank 40.
Thus, the inside of the cooling water tank 40 is divided into the first region A and the second region B by the partition member 60 at a predetermined depth from the water surface.

The water temperature of the portion of the cooling water that receives the thread-like molten resin 11 flowing down from the resin pool 30 rises due to the heat of the thread-like molten resin 11.
Since the conventional cooling water tank is not partitioned into the first region A and the second region B, the portion of the cooling water whose temperature has risen due to the heat of the filamentous molten resin 11 is immediately diffused in all directions, and the other It mixes with the cooling water of the part. Therefore, a large water temperature difference does not occur between the upper side and the lower side of the cooling water.
On the other hand, in the knitted resin manufacturing apparatus according to the present embodiment, the passage of the cooling water in the first region A and the cooling water in the second region B is blocked in the portion where the partition member 60 exists, and the cooling of the first region A is performed. Since water stays, the temperature of the cooling water in the first region A, which has risen due to the heat of the filamentous molten resin 11 flowing down from the resin pool 30, is unlikely to decrease. In addition, since the cooling water on the lower side of the first region A is likely to be mixed with the normal temperature cooling water in the second region B, an increase in the water temperature can be suppressed. Accordingly, in the first region A, the surface layer of about 5 cm from the water surface is relatively hot, the water temperature gradually decreases as the water depth increases, and the water temperature of the second region B is at a water depth of 180 cm where the lower end 60a of the partition member 60 is located. (Approximately 20 to 23 ° C.). Thus, without providing a heating means for heating the cooling water separately, a temperature layer in which the water temperature gradually decreases as the water depth increases can be stably generated. An annealing process for adjusting the crystal speed can be performed during the downward pulling by the take-up machine 50 arranged in the first region A.
When a heat insulating material such as styrene foam is used for the partition member 60 (plate material), the temperature of the cooling water in the first region A can be further prevented from lowering, and the filament shape that flows down from the resin pool 30 at the start of operation. The rise in the coolant temperature of the first region A due to the heat of the molten resin 11 can be accelerated.
Further, the first region A is possible within a range that does not interfere with the take-up machine 50 and the like from the viewpoint of increasing the temperature of the cooling water early at the start of operation and preventing the temperature of the increased cooling water from decreasing. It is preferable to make it as narrow as possible.
In the present embodiment, the cooling water injection port 130 and the cooling water drain port 140 are provided on the second region B side. By providing the water injection port 130 and the water discharge port 140 on the second region B side, it is possible to prevent the temperature of the cooling water in the first region A from changing due to the water injection and the water discharge of the cooling water as much as possible.

  In the knitted resin manufacturing apparatus according to the present embodiment, the temperature when the molten molten resin 11 descends from the resin pool 30 toward the cooling water tank 40 is about 180 ° C. to 220 ° C., and the temperature of the water injected from the water inlet 130 is about In the case of 16 ° C to 23 ° C, the surface water temperature of the first region A is about 60 ° C. Since the water temperature decreases as the water depth increases, the surface layer (about 5 cm from the water surface) is about 52 ° C., the water depth is about 20 ° C., the water depth is about 47 ° C., the water depth is about 40 ° C., the water depth is about 60 ° C. It becomes about 25 ° C. at about 31 ° C. and a water depth of 180 cm.

The take-up machine 50 includes a pair of roller rows including one roller row 51 in which two rollers 51a and 51b are arranged in the vertical direction and the other roller row 52 in which two rollers 52a and 52b are arranged in the vertical direction. Have Roller 51a, 51b, 52a and 52b is the depth _{D 1} direction of the cooling water tank 40 is arranged such that the longitudinal direction. One roller row 51 and the other roller row 52 are arranged to face each other with a predetermined interval that becomes the passage 80 of the knitted resin 12. Note that three or more rollers may be arranged in the vertical direction in one roller row 51 and the other roller row 52. Moreover, it is good also as a pair of roller which consists of one roller arrange | positioned at one side and one roller arrange | positioned at the other.
The surface of the knitting resin 12 comes into contact with the roller 51a, the roller 51b, the roller 52a, and the roller 52b when passing through the passage 80. That is, the take-up machine 50 is not an endless belt method or a caterpillar method in which a belt or the like is looped around a plurality of pulleys arranged in the vertical direction and rotated, but the knitted resin 12 is fed by the rollers 51a, 51b, 52a and 52b. Hold it and pull it down. In addition, the process for anti-slip, such as providing a fine groove, is given to the surface of the roller 51a, the roller 51b, the roller 52a, and the roller 52b.
When an endless belt method or a caterpillar method is used for the take-up machine 50, the cooling water on the upper side and the lower side of the first region A is agitated by rotating an annular belt or the like, and the temperature difference between the two is small. Prone. On the other hand, since the knitted resin manufacturing apparatus according to the present embodiment uses a roller system in which the take-up machine 50 does not use a belt or the like, the stirring of the cooling water on the upper side and the lower side of the first region A is reduced, and the temperature of both It is possible to prevent the difference from becoming small.

A guider 90 is provided between the resin pool 30 and the take-up machine 50. Guider 90, the depth D ₁ direction of the cooling water tank 40 to the longitudinal direction, the first guider 91 provided above the one row of rollers 51, a second guider 92 provided above the other roller train 52 Consists of. The first guider 91 and the second guider 92 are arranged to face each other at a predetermined interval, and are inclined downward toward the thread-shaped molten resin 11. The guider 90 receives the thread-like molten resin 11 and guides it to the cooling water. The distance between the first guider 91 and the second guider 92 is narrower than the width of the thread-like molten resin 11 that flows down from the resin pool 30.
The molten resin extruded from the extruder 20 to the resin pool 30 flows down as a thread-shaped molten resin 11 from the hole in the bottom surface 31 of the resin pool 30. At this time, a part of the filamentous molten resin 11 reaches the guider 90 and then is guided to the cooling water tank 40, and the remaining filamentous molten resin 11 is guided to the cooling water tank 40 without reaching the guider 90. Since the thread-shaped molten resin 11 guided to the cooling water tank 40 after reaching the guider 90 has a higher density than the thread-shaped molten resin 11 guided to the cooling water tank 40 without reaching the guider 90, The knitted resin 12 whose surface is dense with respect to the inner peripheral portion can be formed.
Moreover, the 1st guider 91 and the 2nd guider 92 are each provided with the watering nozzle 93 at the high position side. The watering nozzle 93 is a hollow straight pipe provided along the longitudinal direction of the first guider 91 or the second guider 92, and has a plurality of small holes communicating with the internal cavity on the surface.

On the upper side of the first region A, a submersible pump 100 is disposed between the other roller row 52 and the partition member 60 so as to move up and down as cooling water recovery means. The submersible pump 100 is disposed at a position of a depth of about 30 cm in the first region A, and includes a cooling water recovery port 101 that sucks in nearby cooling water and a cooling water discharge port 102 that discharges the recovered cooling water.
The cooling water discharge port 102 is connected to one end 103 a of the pipe 103. The pipe 103 is bifurcated in the middle, and the other end 103 b is connected to the cavity inside the watering nozzle 93 of each of the first guider 91 and the second guider 92. Therefore, the recovered cooling water is supplied to the upper surface of the first guider 91 and the upper surface of the second guider 92 from the plurality of small holes of the watering nozzle 93 through the pipe 103.
By supplying the relatively high-temperature cooling water collected in this way to the guider 90, adhesion of the filamentous molten resin 11 to the guider 90 can be prevented. Further, the earthing process can be performed in the guider 90 without separately providing equipment for heating the cooling water or the cooling water tank 40.

  In the first region A, a water temperature measuring unit 110 such as a thermometer for measuring the water temperature of the surface cooling water and the water temperature of the cooling water in the vicinity of the submersible pump 100 is provided. The operator can adjust the water temperature of the cooling water supplied to the guider 90 by moving the submersible pump 100 up and down based on the water temperature measured by the water temperature measuring unit 110. That is, when it is desired to lower the temperature of the guider 90 or the first region A, the position of the submersible pump 100 is deepened in accordance with the target water temperature, and cooling water with a lower water temperature is pumped up and supplied to the guider 90. Further, when it is desired to increase the temperature of the guider 90 or the first region A, the position of the submersible pump 100 is made shallow in accordance with the target water temperature, and cooling water with a higher water temperature is pumped up and supplied to the guider 90.

A cooling water discharging means 120 for discharging cooling water on the upper side of the first area A is provided between the one roller row 51 and the first side wall 40a on the upper side of the first area A. When it is determined from the measurement result by the water temperature measurement unit 110 that the cooling water has become too hot, the cooling water discharging means discharges the cooling water at the top of the first area A to lower the water temperature in the first area A. Can do. Therefore, the temperature of the cooling water in the first region A can be adjusted by combining with the vertical movement of the submersible pump 100 or by itself.
The cooling water discharge means 120 is a water pipe having a high temperature water suction port 121 for sucking cooling water at one end and a high temperature water discharge port 122 for discharging cooling water to the outside of the cooling water tank 40 at the other end. is there. The high temperature water discharge port 122 is disposed below the water surface of the cooling water tank 40.
The water pipe (cooling water discharging means) 120 is configured so that the upper side can be rotated around an intermediate portion between one end and the other end, or around the other end.

The apparatus for producing knitted resin according to the present embodiment does not have the guider 90 and the watering nozzle 93, and the uppermost rollers 51 a and 52 a of the one roller row 51 and the other roller row 52 of the take-up machine 50 are the cooling water 40. The three rollers 51 a, 51 b, 51 c are arranged in the vertical direction in one roller row 51, and the three rollers 52 a in the vertical direction are arranged in the other roller row 52. The point from which the 52b and 52c are arranged, and the point by which the cooling water which the submersible pump 100 collect | recovered are supplied to the uppermost rollers 51a and 52a differ.
Roller 51a, 51b, 51c, 52a, 52 b and 52c are the depth _{D 1} direction of the cooling water tank 40 (see FIG. 2) is disposed such that the longitudinal direction. One roller row 51 and the other roller row 52 are arranged to face each other with a predetermined interval that becomes the passage 80 of the knitted resin 12.
The cooling water discharge port 102 is connected to one end 103 a of the pipe 103. The pipe 103 is bifurcated in the middle, and the other end 103b is disposed above the uppermost rollers 51a and 52a. Therefore, the recovered cooling water is supplied to the surfaces of the uppermost rollers 51 a and 52 a through the pipe 103.
By supplying the relatively high-temperature cooling water collected in this way to the uppermost rollers 51a and 52a, the adhesion of the filamentous molten resin 11 to the uppermost rollers 51a and 52a can be prevented. Further, the uppermost rollers 51a and 52a can perform the annealing process without separately providing equipment for heating the cooling water or the cooling water tank 40.

  According to the knitting resin production apparatus of the present invention, knitting can be performed without an additional heating means for heating the cooling water, and by performing an annealing process for adjusting the crystallization speed while pulling downward by a take-up machine. A resin production apparatus can be provided.
