Japanese Patent Laid-Open No. 10-137777 Japanese Patent Laid-Open No. 10-136774 Japanese Patent Publication No. 3-47814

  The method for manufacturing the braided rope as described above is a method of manufacturing a braided float rope developed by the applicant of the present application (Patent Document 3), and filling the unexpanded raw beads into the braided rope. However, in the case of this braided float rope manufacturing method, the raw beads filled in the braided rope are then foamed by heat treatment, and in the braided rope Since the foam expands, a part of the foam enters the stitches of the fiber yarn constituting the braided rope, and the foam is thus stably incorporated in the rope.

  However, since the above-described conventional technique ends in the process of filling the inside of the braided rope with shells or culture soil, the filled shells or culture soil does not get entangled with the fiber yarn constituting the braided rope. When the braided rope is bent or bent, the contents (shell or culture soil) around the bent portion or the inner portion of the bent portion are reduced when the braided rope is bent or bent. Was supposed to move. In addition, when the braided rope is manufactured, the braided rope portion is pulled to realize feeding at a predetermined speed. The pull of the rope portion is filled with contents (shell or culture soil). The braided rope has to be bent at the time of winding, and the braided rope is deformed by the bending (shell or culture soil) movement as described above. It was supposed to trigger.

  The present invention has been made in view of the above-described points, and the object of the present invention is to suppress the flow of contents such as powder or granules incorporated in the braided rope within the rope. It is to provide a braided rope and a manufacturing method thereof.

  Accordingly, the present invention relating to a braided rope incorporating powder or granular material is a braided rope having powder or granular material enclosed therein, and is continuous along the longitudinal direction of the braided rope. A core material is arranged in the vicinity of the center of the braided rope, and a powder or a granular material is enclosed between the core material and a braided fiber yarn constituting the braided rope.

  According to the above configuration, the powder or granular material incorporated in the braided rope is enclosed inside the braided fiber yarn that forms the braided rope. The inner side of this braided fiber yarn (that is, the braided rope) Since the core material exists in the inside of the braided rope, the braided rope incorporates the core material simultaneously with the powder or the granular material. As a result, the powder or granule is present in the hollow cylindrical space formed between the knitted braided fiber yarn and the core material, and the flow is limited by the frictional resistance of both. . In particular, in a state where the braided fiber is knitted into a cylindrical shape and filled with powder or granules, the powder or granules near the center of the braided rope have the highest fluidity, Although it was a cause of a movement of a granular material, the said fluidity | liquidity can be reduced by presence of a core material.

  Further, the present invention relating to a braided rope incorporating a powder or a granular material is a braided rope formed by enclosing a powder or a granular material therein, and a continuous core having irregularities on the surface is formed by the braided above. It is arranged in the vicinity of the center of the braided rope along the longitudinal direction of the braided rope, and encloses powder or granular material between the core material and the braided fiber yarn constituting the braided rope. It is characterized by.

  With the above configuration, the inner surface of the braided rope formed by knitting the braided fiber yarn is configured to have irregularities, so that the powder or granular material filled therein flows in the portion in contact with the braided fiber yarn. In addition, the fluidity of the powder or the granular material in the portion in contact with the core material can be reduced by the unevenness of the core material. Further, when the braided rope is bent or the like, since the powder or granular material is compressed between the braided fiber yarn knitted portion existing as the outer skin and the core material existing inside, the frictional resistance is further increased. Even if the cross-sectional area is reduced, the powder or granular material cannot be easily moved.

  In the above-described material invention, a core material in which knots are formed at a predetermined interval in a continuous direction can be used as the core material. As a result, the powder or granular material is enclosed between one knot and the next knot of the core material, and the movable range of the powder or granular material can be limited.

  Moreover, a braided cord having a spiral loop can be used as the core material. In this case, since the loop protruding from the central braided cord is arranged in a spiral shape, it is possible to limit the movement of the powder or granular material in the longitudinal direction of the braided rope. Although it seems that it can move along the spiral loop, it is actually difficult to move around the core material in the spiral direction in the braided rope.

  The present invention according to a method for manufacturing a braided rope incorporating powder or granular material is a method for manufacturing any of the braided ropes described above, wherein a knitting machine is previously provided below the powder or granular material supply unit. And arranging a core material continuous in the vertical direction while penetrating the supply unit and the knitting machine, and knitting the braided fiber yarn around the core material by the knitting machine, and the braided fiber yarn is knitted. The powder or granule is supplied from the supply section to the position where the core material is lowered according to the speed at which the braided fiber yarn is braided.

  With the above configuration, a braided fiber yarn is knitted to form a braided rope, and at the same time, a rope in which powder or granular material is encapsulated and the core is also arranged near the center can be obtained. Here, the core material can be used in various configurations, and since the core material is disposed through the powder or granular material supply unit, the core material is lowered from the supply unit and braided. Part of the core material that enters the rope will carry the powder or granular material into the braided rope within the supply section.

  According to the present invention relating to a braided rope incorporating powder or granular material, since the core material is present near the center of the braided rope that is easy to move, the contents of the powder or granular material incorporated in the braided rope, etc. A thing can control that a thing flows in the rope concerned. Furthermore, according to the configuration in which the knot is provided in the core material, the flowable range is limited, so that the flow of the contents in the rope can be more efficiently suppressed. Moreover, if it comprises the core material which has a helical loop, the content which moves to the longitudinal direction of a rope can be suppressed.

  Moreover, according to this invention concerning the manufacturing method of a braided rope, the braided rope which has the said effect can be manufactured. In particular, since the core material is disposed through the content supply unit and descends, the content charged in the supply unit is supplied into the rope as the core material descends. , Can enable uniform supply of contents.

(A) is explanatory drawing which shows embodiment of this invention, (b) is IB-IB sectional drawing. It is explanatory drawing which shows the curved state of a braided rope. It is explanatory drawing which shows the manufacturing method of a braided rope. It is explanatory drawing which shows 2nd embodiment of a braided rope. It is explanatory drawing which shows 3rd embodiment of a braided rope.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the first embodiment, as shown in FIG. 1, a core material 2 is arranged inside a braided rope 1, and a powder or granular material (hereinafter referred to as powder) is placed in a gap portion between the two. 3 is enclosed). In the following description, the braided rope 1 means a large-diameter rope portion constituting the outer skin, and the entire structure including the core material 2 and the encapsulating member 3 disposed inside the braided rope 1 is used. The entire braided rope is displayed. Moreover, in FIG.1 (b), although the powder or the granular material 3 is drawn circularly, a shape may differ with the materials which should be enclosed.

  In this embodiment, a braided cord is used as the core material 2 as shown in FIG. This braided cord is formed by knitting a plurality of twisted yarns, the surface of each twisted yarn has a relatively high coefficient of friction, and irregularities are formed on the surface of the braided cord by the stitches of the twisted yarn. Thus, by forming irregularities on the surface of the core material 2, the powder 3 etc. that are in contact with the surface of the core material 2 cannot freely move (slide) on the surface. Etc. 3 is suppressed. More specifically, the powder 3 etc. in contact with the twisted yarn is prevented from moving (sliding) due to the frictional resistance of the twisted yarn, and the aggregate of the powder 3 etc. located in the concave portion of the braided cord surface is the twisted yarn. The movement (sliding) can be suppressed even at a position where no contact is made.

  On the other hand, since the same stitches as the outer surface of the braided rope 1 are formed on the inner surface of the braided rope 1 constituting the outer skin, the braided fiber yarn forms irregularities on the inner surface. Existing. Therefore, movement (sliding) of the powder 3 etc. in contact with the inner surface of the braided rope is suppressed by the unevenness caused by the stitches of the braided fiber yarn. Depending on the friction coefficient of the braided fiber yarn, movement (sliding) due to frictional resistance can be suppressed in addition to suppression of movement (sliding) due to the unevenness of the stitches.

  Therefore, the powder etc. 3 is enclosed between the braided rope 1 and the core material 2 (FIG. 1 (b)), so that the entire braided rope R has the powder etc. 3 both externally and internally. It is regulating. That is, among the powder 3 and the like 3 enclosed in the hollow interior of the braided rope 1, those near the center of the entire braided rope R are prevented from fluidizing by the core material 2 disposed near the center, and In the case of the braided rope 1, fluidization is suppressed by the presence of the braided rope 1. Therefore, the easy flow range is limited to, for example, the powder 3 located in a range appropriately separated from both 1 and 2.

  With the configuration as described above, since a part of the powder 3 can flow, the entire braided rope R can have an appropriate flexibility and suppress excessive flow of the powder 3. Thus, it is possible to prevent the powder 3 and the like from being partially different in density. Further, by suppressing the flow in the longitudinal direction, it is possible to suppress a decrease in the cross-sectional area of the curved portion in a state where the entire braided rope R is curved.

  In this regard, as shown in FIG. 2, in order for the entire braided rope R to bend, the braided rope 1 of the curved portion must have different lengths of the outer peripheral portion and the inner peripheral portion. When 2 is located at the center of the entire braided rope R, the inner peripheral portion contracts (actually, shrinkage is caused by compression from the longitudinal direction), and the outer peripheral portion expands (actually Expansion is performed by expanding the stitches (see FIG. 2A). As a result, the density change of the powder 3 and the like is suppressed without causing a large change in the cross-sectional area. Further, depending on the curved state, as shown in FIG. 2 (b), the core material 2 may move inside the braided rope 1 to the inner peripheral side. Even in such a case, since the core material 2 moves while compressing the powder 3 or the like, the movement can be reduced. In any state, compared with the conventional example in which the powder 3 etc. is simply enclosed in the hollow braided rope 1 in which the core material 2 is not disposed, the conventional example in which the powder 3 near the center can freely flow. It is much better than.

  Next, an embodiment according to a manufacturing method of the braided rope (the entire braided rope R) having the above configuration will be described. As shown in FIG. 2, the braided rope 1 is knitted by a knitting machine 4, and powder or the like 3 is enclosed in the middle of the knitting. The knitting machine 4 is configured to move the driving force of the motor M by holders H1, H2,... Where the bobbins B1, B2,. And the braided fiber yarn 11 can be knitted by repeating the running. The holders H1, H2,... Move along the running grooves 41 provided on the table T, and the types of ropes knitted according to the movement trajectory are different.

  Here, in the braided rope 1 to be knitted, the braided fiber yarn 11 is knitted in the upper part of the knitting machine 4, and the knitted part is sent downward. The body 3 etc. flows in. Therefore, the powder 3 and the like is stored in a hopper 5 installed above the knitting machine 4 and flows down from the lower supply port 51 to the braided rope 1. The core material 2 disposed inside the braided rope 1 is prepared as a continuous long one and is inserted into the braided rope 1 to be knitted. That is, the continuous long core material 2 is disposed so as to penetrate the knitting machine 4 and the hopper 5, and the knitting of the braided rope 1 by the knitting machine 4 is performed around the core material 2. The braided rope is lowered as the knitting of the braided rope 1 progresses, and the core material 2 is also lowered according to the lowered amount (feed amount). Then, the core material 2 that passes through the hopper 5 and reaches the braided rope 1 descends while adhering powder or the like 3 stored in the hopper 5, and the core material 3 is powder or the like. 3 functions as a supply conveyor. Thereby, the amount of enclosing powder 3 etc. can be made constant.

  The knitted braided rope 1 is lowered by winding the core material 2 with a roll 6. Thereby, the external force which is compressed from the outside does not act on the braided rope 1, and it is possible to prevent the powder 3 and the like from moving during the winding operation. Although the core material 2 and the braided rope 1 are moved by a distance corresponding to a predetermined feed amount by winding the core material 2, it does not give a strong tensile force to the core material 2. This is about the pulling force required for feeding and conveying necessary for taking out the braided rope after knitting and feeding and conveying necessary for supplying the core material 2 from the hopper 5 to the knitting machine 4. In addition, after winding the core material 2 positioned at the head, the entire braided rope R is wound, but in this case as well, the core material 2 at the head is not pulled by the braided rope 1 alone. Further, the pulling force by the subsequent core material 2 that is continuous is sufficiently exerted.

  Next, a second embodiment of the braided rope (entire braided rope) will be described. In this embodiment, as shown in FIG. 4, the braided rope 101 is formed by knitting a braided fiber yarn in the same manner as in the first embodiment, and the core material 102 includes a loop 122 from a braided cord 121 that is a main body portion. The thing provided so that it may protrude is used. As shown to Fig.4 (a), it arrange | positions the said core material 102 inside the braided rope 101 similarly to embodiment first. The loop 122 is constructed by knitting with a knitting machine while pulling out a part of the twisted yarn constituting the braid cord 121 during knitting. Accordingly, since a part of the twisted yarn knitted in the spiral direction is drawn out, the virtual plane surrounded by the twisted yarn of the loop 122 is formed in a substantially spiral shape with respect to the longitudinal direction of the braided cord 121.

  As shown in FIG. 4B, the main body portion of the core material 102 is obtained by arranging the core material 102 in which the spiral loop 122 protrudes from the braided cord 121 in this manner. The braided cord 121 is arranged near the center of the braided rope 101, and the loop 122 is in contact with or close to the inner surface of the braided rope 101. Therefore, when powder 103 is enclosed between the braid cord 121 and the inner surface of the braided rope 101, the powder 103 is moved in the longitudinal direction of the braided rope 101 by the loop 122. It will be limited.

  In particular, the movement of the powder 103 that contacts the surface of the braided cord 121 and the powder 103 that contacts the braided fiber yarn existing on the inner surface of the braided rope 101 is limited by the respective frictional resistance and unevenness. (Similar to the first embodiment) However, the fluidity of these intermediate layers was relaxed. This relaxation of fluidity is important for facilitating the bending of the braided rope 101, but depending on the fluidity of the powder 103 to be encapsulated, it is necessary to further suppress the flow. Therefore, the presence of the loop 122 protruding from the braid cord 121 as described above in the intermediate layer can restrict the flow of the powder 103 or the like. Since the braided cord 121 having the loop 122 is configured by pulling out a part of the twisted yarn constituting the braided cord 121, the loop 122 can use a normal twisted yarn, but the shape of the loop 122 is strong. In order to achieve this, it is possible to use resin yarn instead of twisted yarn. In this case, the effect of suppressing the flow of the powder 103 or the like by the loop 122 can be stronger than that of the core material 102 using twisted yarn.

  The method for manufacturing the second embodiment having the above-described configuration is the same as the embodiment of the manufacturing method already described. Accordingly, since the core material 102 passes through the hopper 5 (FIG. 3) and is supplied to the knitting machine 4 (FIG. 3), the loop 122 of the core material 102 of the present embodiment acts to scrape out the powder 103 and the like. Thus, an appropriate amount of powder 103 and the like scraped out by the loop 122 is enclosed in the braided rope 101.

  Next, a third embodiment of the braided rope (entire braided rope) will be described. In this embodiment, as shown in FIG. 5, the braided rope 201 is formed by knitting a braided fiber yarn in the same manner as in the first embodiment, and the core material 202 is formed by tying the core material 202 at an appropriate position. What has the knot 211 comprised is used. The core material 202 having the knot 211 is disposed inside the braided rope 201 as shown in FIG. 5A, and this is the same as in the first embodiment.

  Here, the core material 202 used may be a braided cord formed by knitting twisted yarn, but in the present embodiment, a resin yarn is used. Such a change of the material may be determined by the fluidity of the powder to be sealed. That is, as shown in FIG. 5 (b), when the core material 202 is disposed inside the braided rope 201, the most swollen portion of the knot 211 comes into contact with the inner surface of the braided rope 201. Or approach. As shown in the figure, since this knot 211 is intermittently present at an appropriate interval, a certain amount of space is placed between one knot 211 and the next knot 211 located next to it. A portion is formed, and the powder or the like 203 is filled in the space portion, whereby the flow of the powder or the like 203 is restricted. At this time, since the flow of the powder etc. 203 is allowed only in the space part, the stationary state of the powder etc. 203 becomes stable. Further, when it is necessary to restrict the flow of the powder 203 or the like, the flow can be restricted even inside the space portion by changing the material of the core material 203 to the braid cord, so that further stabilization is achieved. be able to.

  The manufacturing method of this embodiment is also based on the method already described. Accordingly, when the core material 202 passes through the hopper 5 (FIG. 3), the core material 202 acts to hold the powder 203 between the knot 211 and the knot 211 of the next order, and an appropriate amount of powder 203 Thus, the density of the powder etc. 203 in the entire braided rope R can be made substantially constant.

  The embodiments of the present invention are as described above, but various modes can be taken without departing from the spirit of the present invention. For example, in the first embodiment, the braid cord is used as the core material 2, but this considers the frictional resistance of the surface, and there is little frictional resistance depending on the fluidity of the powder 3 to be encapsulated. A raw material (for example, a resin string) can be used. Moreover, in order to adjust friction resistance, the magnitude | size of the unevenness | corrugation provided in the surface of the core material 2 may be changed, and it adheres to the surface of the core material 2 by apply | coating an adhesive material or an adhesive material depending on the case. It is also possible to form irregularities with the fixed powder etc. 3 while fixing the powder etc. 3. In any case, it is not limited to the aspect described in the embodiment.

  The present invention can be used as a water purification rope depending on the properties of the encapsulated powder and the like, and can also be used as a rope-shaped medium by enclosing culture soil and the like. Furthermore, the fertilizer supply rope for plant cultivation can be comprised by enclosing a fertilizer.
