Abstract

(57) [Abstract] [Problem] To easily and efficiently open and close a flexible container outlet. SOLUTION: When a flexible container 1 filled with a product is suspended, a force for pulling the rope 4 around a discharge port 3 in the direction of an arrow in FIG. 1 acts, but the load is received by a locking portion of a main body 10. Therefore, the tensile force is not transmitted to the knot 6. Further, since the load applied to the rope 4 is also supplemented by the bent portion, the knot 6 is not tightly tightened, and the knot 6 can be easily untied.

[Technical field to which the device belongs]

 This invention relates to a binding tool for opening and closing the product discharge port of a flexible container.

[0002]

[Prior art]

 Flexible container is an abbreviation for a mass transport bag (flexible container) mainly used for transportation and storage of powder and granular material. The flexible container, as specified in JIS Z 1615, is made of a flexible material such as a cylindrical or prismatic foldable rubber cloth that can be used repeatedly over a long period of time, or a resin-processed cloth.

FIG. 4A is a side view of a general flexible container 1 having a product inlet (not shown) at the top and a product outlet 3 at the bottom 2. As shown in the bottom perspective view of FIG. 4B, a binding rope 4 is provided around the periphery, and the discharge port 3 can be opened and closed by tightening or loosening the binding rope 4. It has become.

In this type of flexible container 1, conventionally, as shown in the bottom view of FIG. 5, the outlet 3 is closed by using a cylindrical auxiliary tool 5 made of rubber or synthetic resin. That is, when tightening the binding rope 4, the auxiliary tool 5 was moved in the central direction (arrow direction) and then the binding rope 4 was tied behind the auxiliary tool 5. Reference numeral 6 is a knot of the rope 4.

When the flexible container 1 is suspended, the weight of the filled product exerts a force to spread the rope 4 around the outlet 3 of the flexible container 1 so that the knot 6 is firmly tightened and the knot 6 is unwound. Is often difficult. Due to the troublesome work of unraveling such a tight knot 6, the rope 4 was unavoidably cut to take out the product, but at that time, the discharge section 3 is often cut off by mistake. Wasteful materials and labor were spent on these repairs, and the rotation rate (operation rate) of the flexible container 1 was significantly reduced.

In addition, the above-described series of operations is a dangerous operation because an operator must enter under the suspended unstable weight of 0.5 to 1.5 tons. It was

[Problems to be solved by the device]

 An object of the present invention is to provide a tying tool that can easily and efficiently open and close the outlet of a flexible container.

[0008]

[Means for Solving the Problems]

 The present invention relates to a binding tool that opens and closes an outlet of a flexible container by operating a binding rope arranged around the outlet of the flexible container, wherein the binding tool includes a binding rope and a main body for operating the rope. The binding tool main body has a locking portion that engages with the binding rope, and a pair of sliding holes penetrating the side of the main body are formed so as to intersect with each other. It is characterized by passing through both ends.

It is preferable that the locking portion is formed by an acute ridge angle formed by a side wall surface of the binding body and an inner wall of the sliding hole on the flexible container outlet side.

Further, it is preferable that the sliding hole is provided with a bent portion having an obtuse angle with respect to a ridge angle of the locking portion.

[0011]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] Fig. 3 is a front view and a bottom view showing an embodiment of a binder main body that constitutes a binder for a flexible container outlet, and the rounded block-shaped binder main body 10 is an integrally molded product. Is desirable. That is, as will be described later, a shearing force is generated in the binder body 10 by the tensile force applied to the rope 4, and therefore, in order to increase the strength of the binder body 10, it is preferable to use a molding process such as synthetic resin. The body 10 is rounded so that it fits comfortably in the hand in consideration of safety.

As shown in FIG. 3, the binding tool body 10 is provided with a pair of sliding holes 12, 12 for passing the binding rope 4 through the side portions thereof so as to intersect in an X shape. . However, the X-shaped sliding holes 12 and 12 are formed in different steps.

The sliding holes 12, 12 are provided with a locking portion A that engages with the binding rope 4. In the present embodiment, the locking portion A is formed by an acute ridge angle formed by the side wall surface of the binding tool body 10 and the inner wall of the sliding hole 12 on the flexible fiber outlet side. The angle of the ridge should be as small as possible so that a strong locking force with respect to the rope 4 is exerted.

FIGS. 2 (a) and 2 (b) are a front view and a bottom view showing another embodiment of the tying body, wherein the tying body 10 made of a block having a circular front shape has a plurality of tying members. Sliding holes 12, 12 having bent portions are formed. That is, the bent portion A formed by the acute ridge angle on the flexible container discharge port side has the same function as that of the embodiment shown in FIG. 3, but in the present embodiment, the bent portion A is further bent inside the main body 10. A portion B and a bent portion C are formed. Since the bent portion B and the bent portion C are for reinforcing the locking force with respect to the rope 4 at the bent portion A, the ridge angle can be made obtuse than the ridge angle of the bent portion A.

In the present embodiment, the openings of the sliding holes 12, 12 on the side of the knot 6 are expanded in a tapered shape so that the binding rope 4 can be passed easily and when the rope 4 is loosened, it is smooth. It is designed to slide.

Next, a method of operating this binding tool will be described. First, when closing the outlet 3 of the flexible container 1, holding the tie body 10 and pulling the tie rope 4 in the direction opposite to the outlet 3 to move the tie body 10, the rope 4 The sliding hole 12 is smoothly slid and tightened. Then, when the outlet 3 is closed, the rope 4 is simply knotted (when the knot is untied, the rope is pulled off to pull it off) and the knot 6 is made so that the rope 4 will not be displaced.

On the other hand, when the flexible container 1 filled with the product is suspended, a force for pulling the rope 4 around the outlet 3 in the direction of the arrow in FIG. Therefore, the tensile force is not transmitted to the knot 6. Further, since the load applied to the rope 4 is also supplemented by the bending portion B and the bending portion C, the knot 6 is not tightly tightened and the knot 6 can be easily untied. it can.

[Effect of device]

 According to the binding tool of the present invention, the knot of the rope that binds the outlet of the flexible container can be easily untied. Therefore, the opening / closing work of the discharge port can be performed extremely easily and efficiently.

By using the tying device of the present invention, it is not necessary to cut the tying rope, so that the rope can be used repeatedly, and it is necessary to spend extra material and labor such as cutting of the flexible container discharge part. Disappears. In addition, there is no need to thread the binding rope around the outlet. Naturally, the blades used to open the FIBC outlet are no longer needed, which is extremely safe from the standpoint of workability.
