The present invention relates to a spigot formed with a plurality of inclination reinforcement portion, and more particularly, a plurality of inclinations in which a weft and a plurality of inclinations are repeatedly woven in a predetermined portion of the circumference in the sack formed by weaving the weft and the inclination. The present invention relates to a spigot formed with a plurality of inclination reinforcing sections for simultaneously maintaining the shape of the spigot and improving the stiffness by forming the reinforcing section.

The sack is used to hold various bulk contents, including grains and solid powders. The heds need to have sufficient tensile strength and abrasion resistance and are as light as possible to prevent an increase in product weight. For this reason, polypropylene having a higher tensile strength than that of nylon is widely used.

Figure 9 is a plan view schematically showing a state containing the contents in a conventional sack. As shown in FIG. 9, since the conventional rod 70 is made of a synthetic resin which is relatively flexible in shape change due to its flexibility, when the contents of the rod are filled with the bottom of the rod 72, the base 70 is rectangular. ) Does not maintain the shape of the cube and the circumference 71 bulges bulging, resulting in a large volume.

When the sack filled with contents does not maintain the shape of the cube and swells in the circumferential direction, the number of stools that can be loaded in the width direction of the warehouse or container decreases as the width of the stool increases, which means that a large amount of stools cannot be loaded. This led to an increase in logistics costs.

Therefore, it was necessary to maintain the shape of the cube even after the contents were filled in the sack. Various improvements to the harness have been attempted to meet these demands.

Figure 10 is a plan view schematically showing a spigot formed with a conventional inner reinforcement. As shown in FIG. 10, the stem 80 formed with the inner reinforcement part is reinforced with a fabric piece connecting each inner side of the stem 80 at a portion adjacent to the corner to prevent bulging of the circumference of the stem. The inner reinforcement portion 81 that connects the inner surface of the stem 80, even if the contents filled in the stem pushes the side of the stem in the circumferential direction because the inner reinforcement portion 81 holds the side of the stem inwards Bulging in the direction is prevented and the shape of the cube is maintained.

In order to form an inner reinforcing part in such a sack, a process of attaching a separate woven fabric piece to the inner side of the stool is added, thereby increasing the manufacturing process of the sack, thereby lowering productivity.

In addition, since the inner reinforcement attached to a part of the side of the stem is suppressed from expanding the stem outward, in order not to drop the portion where the inner reinforcement is coupled by the pressure of the contents, reinforce the strength of the portion where the inner reinforcement is coupled at the side of the stem. I had to.

The present invention has been made to solve the above problems of the prior art, an object of the present invention by forming a plurality of inclination reinforcement portion having a plurality of inclined woven with one weft yarn around the sack for receiving the bulk water By maintaining the shape of the to increase the loading capacity of the sack in a certain space and to provide a stool formed with a plurality of slope inclined reinforcement portion to increase the strength of the sack to accommodate more contents.

An object of the present invention described above is a woven woven with wefts and warp yarns, at least one plurality of warp yarn warp reinforcement woven in a continuous direction of at least two warp yarns and one weft yarn is arranged in the vertical direction It is achieved by the spigot formed plural bone inclined reinforcement, characterized in that formed.

In order to achieve the above object, the spigot includes a rectangular bottom surface and four rectangular side surfaces connected to the corners of the bottom surface, wherein the plurality of inclined reinforcement portion is formed symmetrically two on each of the side surfaces. desirable.

Moreover, in order to achieve the said objective, it is preferable that the said at least 2 inclinations which comprise the said plural book inclination reinforcement part are arrange | positioned side by side in the direction of the surface of the said stem.

At least one strip is preferably coupled to one end of the plurality of inclined reinforcement portions to lift the stem to achieve the above object.

In addition, the spigot includes a rectangular bottom surface and the four rectangular sides connected to the edge of the bottom surface, the plurality of inclined reinforcement portion has a width of 1/4 or more of the width of the side and in the center of each side It is preferable to form one by one.

Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the configuration of the spigot formed a plurality of inclined reinforcement portion according to a preferred embodiment of the present invention. Like numbers refer to like elements throughout.

1 is a perspective view showing a spigot formed with a plurality of inclination reinforcement portion according to a preferred embodiment of the present invention. As shown in Figure 1, the spigot formed with a plurality of inclined reinforcement portion according to a preferred embodiment of the present invention consists of a substantially rectangular bottom portion 2 and the side portion (1) forming a circumference and the top of the side portion (1) A plurality of lifting strips 20 are attached to the portion by external sound quality or the like.

The hemp is formed by the bottom portion 2 having a quadrangular shape and the side surface 1 extending substantially vertically from the bottom portion 2 so as to maintain the shape of the cube.

The side surface 1 of the stem is made of four according to the shape of the bottom portion 2, each side 1 is formed with a plurality of inclined reinforcement portion 10 in the longitudinal direction.

Figure 2 is a side view showing a spigot formed of a plurality of inclination reinforcement portion according to a preferred embodiment of the present invention from one side. As shown in FIG. 2, the plural-bone inclined reinforcement portion 10 formed on the side surface 1 of the stem has a narrow shape compared to the length thereof, and is vertically symmetrical to both edges of the side surface 1 of the stem. Are made up. The lifting strip 20 is sewn on and attached to the upper end of the plurality of inclined reinforcement portions 10 among the stem sides. The width of the plurality of inclination reinforcement portion 10 is made of approximately 70 ~ 100mm and if the width is too large may burden the weaving machine.

Figure 3 is an enlarged view showing the magnified plural-bone inclined reinforcement portion and the adjacent portion in accordance with a preferred embodiment of the present invention, Figure 4 is a cutaway of the plural-bone inclined reinforcement portion in accordance with a preferred embodiment of the present invention It is a cross section. As shown in Figures 3 and 4, the plural bone inclined reinforcement portion formed on the side of the stem is formed by weaving repeatedly in one unit of the weft yarn 3 and the two warp yarns 12 in a unit. The right adjacent portion of the reinforcement part 10 is a structure in which one weft yarn 3 and one warp yarn 5 are woven, which is different from the structure of the reinforcement part 10. In other words, the warp portion is woven with the weft yarn in units of plural copies.

Here, the weft yarn and the warp fabric weave alternately up and down is a fact known to those skilled in the art for the fabric structure, so a detailed description thereof will be omitted.

Figure 5 is a plan view showing a process in which the slope is introduced to form a plurality of slope inclined reinforcement portion according to the present invention. As shown in Fig. 5, the plural-slope inclined reinforcement portion of the stem according to the present invention is inserted between the two inclinations 12 between the body 50 for guiding the inclination in the process of weaving the side of the stem. It is formed. The other part of the stem other than the reinforcement is formed by inserting one inclination 5 between the bodies 50. Here, the process of weaving the warp and the weft will be omitted since it will be apparent to those skilled in the art.

Figure 6 is a side view of the spigot formed a plurality of inclined reinforcement portion according to another embodiment of the present invention. As shown in FIG. 6, the spigot formed of the plural-bone inclined reinforcement part according to another embodiment of the present invention has a plurality of the slanted inclination reinforcement parts 210 and 220 formed on each side 200 adjacent to both edges of the plenum side. It is formed in the center of the side as well as the wealth. The reinforcement portion 220 at the center of the side functions to further suppress the swelling of the sack and increases the role of reinforcement. The reinforcement portion 210 formed on both sides is approximately 70 to 100 mm in width, and the central reinforcement portion 220 is formed to be approximately 20 to 100 mm in width.

Figure 7 is a side view of the spigot formed a plurality of inclined reinforcement portion according to another embodiment of the present invention. As shown in FIG. 7, the stem according to another embodiment of the present invention has a plurality of inclination reinforcement portions 110 formed only at the center of the side of the stem and the width of the reinforcement portion 110 at the center of the stem side 100. Is formed in more than 1/4 of the width. The lifting strip 20 is attached to both sides of the central reinforcement 110.

Hereinafter will be described in detail the working effect of the spigot formed in the plural-bone inclined reinforcement portion according to the preferred embodiments of the present invention.

The plural-bone inclined reinforcement part of the stem according to the present invention has a structure in which two warp yarns are woven with one weft yarn and have a higher tensile strength in the same area as the structure is more dense than other parts on the side of the burlap, and the strain against load is also different. Smaller than the part. In addition, as shown in Figure 4, the two inclination of the plurality of inclination reinforcement portion is arranged side by side in the face direction of the stool, so that the constant without increasing the thickness of the stool. That is, since the reinforcement is not protruding from the rod, even if there is friction between the rods, the reinforcement does not wear better.

In addition, the formation of a plurality of inclined reinforcement on the stool does not require a separate process, but at the same time as weaving different parts of the stool, because the number of inclinations inserted into the bodies is different, so the reinforcement is formed in one process. This leads to a reduction in manufacturing cost and process, thereby improving productivity.

Figure 8 is a cross-sectional view showing a state filled with the contents according to the sack according to the present invention. As shown in FIG. 8, when the contents are filled in the stem according to the present invention, the side 1 of the stem is subjected to pressure to receive a tensile force, wherein the reinforcement 10 has a different strain rate from the side of the stem 1. Since it is smaller than the portion, the reinforcing portion 10 serves to pull the portion adjacent to the reinforcing portion 10. Therefore, the side 1 of the stem is prevented from inflating and expanding by the pressure of the contents.

The plural-bone inclined reinforcement formed adjacent to the edge of the stem is dense and rigid compared to other parts of the side of the stem, so that the edge portion of the stem has a small radius of curvature where the contents are filled. Do it. The smaller radius of curvature of the edge of the stem means that the stem is closer to the cube.

The vertical direction in which the plurality of inclined reinforcement portions are formed, that is, the vertical direction, refers to the direction from the inlet to the bottom.

Since the reinforcement part is formed in a predetermined part on both sides of the rod and the strip is attached thereto, the attachment position of the strip can be easily grasped and the attachment process is made quickly, and it also serves to prevent the attachment position from shifting during the attachment process. The quality is improved. In addition, the lifting strip is attached to the high-strength reinforcement portion, the lifting strip is more firmly attached to increase the safety when lifting.

The additional reinforcement in the center as well as on both edges of the side of the stem is to increase the pull function of the side of the stem to prevent bulging in the lateral direction as much as possible.

Since the plural-bone inclined reinforcement has a dense weave structure compared to other portions of the rod, it pulls the other portions of the rod, thereby suppressing the circumferential volume of the product and maintaining a square shape. In the reinforcement part, since the number of inclinations is twice as large as that of the other parts of the rod, the frictional force against the weft is also doubled, and the amount of extension in the width direction is smaller than that of the other part of the rod.

As the number of slopes included in the whole yard increases, the maximum capacity of the yard increases.

In addition, since the method of forming the reinforcing part is made in the weaving sack itself without any additional process, there is an advantage that the productivity of the sack does not fall even if the reinforcing part is formed.

When one plural slanted reinforcement is formed on each side of the stem, the width of the reinforcement is formed to be 1/4 or more of the width of the side, which means that the reinforcement does not maintain the shape of the edge adjacent to the edge of the stem. In this case, since the shape of the side that is inflated to the outside is directly limited, the width of the reinforcement part is sufficiently wide to sufficiently suppress the bulging of the central portion.

In the preferred embodiment of the present invention, but the structure of the top of the sack is shown, the structure that covers the top of the sack is obvious to those skilled in the art can be easily predicted various structures can be selected in the embodiment of the present invention to cover the structure No concrete city. However, not showing the structure covering the top of the stem is not limited to the scope of the present invention.

The inclination forming the reinforcement part is not only to form a plurality of bones all over the reinforcement part, but also various modifications are possible, for example, two inclination parts and one inclination part may be alternately formed. That is, when the other part of the stem is made of 12 × 12 (the number of weft copies × inclined copies), the reinforcing part can be freely selected as 24 × 12, 20 × 12, 18 × 12, etc., based on the number of weaving copies.

Since the yarn used for the sack according to the present invention is not limited to the thickness of the yarn, it is possible to apply all from the low to the near.

In addition, as a weaving machine for weaving the spigot with the plurality of inclined reinforcement portions, a circular weaving machine, a flat weaving machine, a reverse weaving machine, or the like can be used.

The inclination of the plurality of bones, which is a unit for forming the reinforcing portion, is not limited to two and may be three or more if the weaving machine is not burdened.

In addition, in the preferred embodiment of the present invention, but the pattern of the warp reinforcement portion of the weave is repeated in the weaving of a plurality of warp yarns, but the present invention is not limited to this, is manufactured integrally at the time of manufacture of the weave fabric In order to satisfy the demand, we adopt a configuration in which one weft yarn and one warp yarn are woven in the manufacture of the hemp fabric.In this case, the one warp yarn is used to maintain the strength by using a thicker denier than the weft yarn. It is also possible.

In addition, although a belt structure is used in the form of a lifting strip in the preferred embodiment of the present invention, the present invention is not limited to this, and all four corners of the top of the hem are rounded to form a separate tubular shape and the inside of the tube is formed. It is also possible to adopt a configuration to insert the rope to penetrate and to lift the rope exposed out of the tube at the four corner portions. It is also possible to form the tunnel by folding the fabric end to the bottom only at two symmetrical corners of the top of the rod, and to lift the rod by inserting the lifting bars at the end of the tunnel.

According to the spigot formed with a plurality of inclined reinforcement portion according to a preferred embodiment of the present invention having the above-described configuration, the sack packing the contents by the inclined reinforcement portion is prevented from bulging sideways to increase the volume in the circumferential direction Since the product is kept close to the hexahedron shape, it is possible not only to load a large amount of product in a certain space when loading the product, but also to stably load the product without tilting the product.

In addition, the process of forming a plurality of inclined reinforcement portion is made in the process of weaving the sack fabric without going through a separate process, but at this time, because the number of inclined number of the portion where the reinforcement is formed in a plurality of different forms the reinforcement portion without addition of the process Therefore, even if the reinforcing portion is formed, the productivity does not decrease at all.

Since the reinforcing portion may serve as an indicator for determining the position and stitching portion to which the lifting belt is attached, the process of attaching the lifting belt is faster and more accurate.

In addition, it is also possible to use one warp that is higher denier than the weft yarn in forming the reinforcement part of the hemp, and in this case, the warp of the high denier is added only to a certain part in the process of manufacturing the hemp fabric. In this case, since the reinforcing portion is formed at the same time as producing the fabric in a single process, it is possible to obtain the same strength as using a plurality of inclined portions, and the productivity is not reduced at all.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will include such modifications and variations as fall within the spirit of the invention.
