The flexible tube 210 of the present invention can be flexibly rotated. The flexible tube 210 is configured with a hollow formed therein, and a cable or hose for supplying power or water to the corresponding industrial machine is inserted into the hollow. The flexible tube 210 of the present invention is formed by alternating the concave portion and the concave portion in the longitudinal direction.

On the other hand, the flexible tube 210 is mounted on an industrial robot and is used after inserting a cable or hose. However, depending on the working environment, for example, in the case of a welding working environment using a robot, friction of a specific part of the robot and the tube occurs due to the movement of the robot, and as illustrated in FIG. 1, a tube is damaged. do.

Hereinafter, the damaged flexible tube is referred to as a first flexible tube.

Figure 2 shows a flexible state of the flexible tube according to an embodiment of the present invention.

The flexible tube shown in FIG. 2 is a flexible tube different from the first flexible tube configured to repair the broken flexible tube shown in FIG. 1. Hereinafter, another flexible tube for repairing the first flexible tube is referred to as a second flexible tube.

The first flexible tube and the second flexible tube are made of the same material, and the same shape in which the convex portions 11 and the concave portions 12 are alternately continuously formed is preferable.

However, while the first flexible tube 210 has a structure without a cut surface, the second flexible tube 10 is made in a state in which one side is cut in the longitudinal direction. That is, the inside and outside of the second flexible tube 10 is opened through the cutting part 17.

In the drawing shown, one side is cut in the longitudinal direction of the second flexible tube 10 as a whole.

The second flexible tube 10 of the present invention is a structure that can be bent while having a certain curvature because it has a structure in which it is folded in a corrugated shape in which acid and valley are formed.

In the present invention, the acid portion is referred to as an iron portion 11, and the bone portion is referred to as a recess portion 12. In the second flexible tube 10, the outer portion becomes a shape away from each other, and the inner portion becomes a shape adjacent to each other.

In the second flexible tube 10 shown in FIG. 2, the cutting part 17 is located inside while being bent.

The characteristics of the first and second flexible tubes described above are almost the same except for the presence or absence of the cutting portion 17.

Figure 3 shows a perspective view of a fixing device for fixing a flexible tube according to an embodiment of the present invention. And Figure 4 shows a side view of the fixing device according to an embodiment of the present invention. And Figure 5 shows a cross-sectional view showing the groove formed on both sides of the fixing device according to an embodiment of the present invention.

The second flexible tube 10 according to the present invention has a state in which one side is cut in the longitudinal direction. When an external force is applied to the flexible tube having such a structure, a gap is formed while the cutting part 17 is shifted.

Therefore, in the present invention, a fixing device 50 for fixing the cutting portion 17 of the second flexible tube 10 is further provided.

The fixing device 50 is preferably made of the same material, such as plastic, flexible plastic, and resin forming the flexible tube 10.

The fixing device 50 includes an upper member 51 and a lower member 53, and the upper member 51 and the lower member 53 in the longitudinal direction of the inner portion formed in the middle of the extension (54) By this, the upper member 51 and the lower member 53 are integrally connected. The groove portion 57 having the same groove shape is formed on the left side and the right side of the fixing device 50 around the extension portion 54.

The upper member 51 forms a plurality of first protrusions 59 toward the lower side, and the lower member 53 faces the plurality of second protrusions so as to deviate from the first protrusion 59 toward the upper side ( 58). A plurality of the first protrusion 59 and the second protrusion 58 are formed at regular intervals.

In the lower member 53, the spacing a between the second protrusion 58 and the adjacent protrusion is preferably determined in a range of 5 mm to 10 mm. Likewise, it is preferable to determine the distance between the first protrusion 59 of the upper member 51 and the adjacent protrusions in the range of 5 mm to 10 mm. At this time, the gap between the protrusions formed in the lower member 53 and the gap between the protrusions formed in the upper member 51 should be determined in the same range. The gap (a) between the protrusions is determined in the above range because, when configured to be smaller or larger than the above-mentioned range, there is a possibility that the fastening state of the iron portion of the tube to be inserted is not hard and may be separated.

As the space between the first protrusion 59 and the second protrusion 58 and the space between the upper member 51 and the lower member 53 are connected, a groove 57 is formed, and the groove 57 is The iron part 11 of the cable carrier 10 is inserted and fastened.

The groove portion 57 of the fixing device 50 constitutes a groove so that the iron portion 11 of the flexible tube 10 can be inserted, but separation does not occur in the engagement state between the iron portion 11 and the groove portion 57. To avoid this, the fastening state of the two components needs to be firmly configured. Therefore, the numerical values of the iron portion 11 and the numerical values of the groove portion 57 need to be maintained relative to each other for the two configurations. The groove portion 57 is configured in a concave groove shape to be engaged with and fixed to the iron portion 11 of the flexible tube 10.

In the embodiment of the present invention, the height (b) of the groove portion 57 is preferably determined in the range of 8mm to 10mm. The height (b) is determined in the above range because, when configured to be smaller or larger than the above range, the fastening state of the iron portion of the tube to be inserted is not hard, and may be separated.

In addition, the groove portion 57 included in the one fixing device 50 shows four configurations in FIG. 3 and is shown to be able to be combined with the four iron portions 11 of the flexible tube 10. It is not limited, and it may be possible to adjust variably. In addition, a plurality of fixing devices 50 may be configured on the cutting portion 17.

Looking at a cross-sectional view of the fixing device 50 shown in Figure 5, the thickness of the extension portion 54 between the upper member 51 and the lower member 53, 65, and the center of the extension 54 It can be seen that the grooves 57 extend at the same depth 67 on the left and right sides.

The width (c) of the fixing device 50 is preferably determined in the range of 10 mm to 17 mm. In this way, when the width (c) of the fixing device 50 is determined to be within the above range, if the structure is smaller than or equal to the above range, the fastening state of the fixing device may be difficult to separate, and the configuration may be larger than the above range. This is because there is a possibility that it is inadequate for the function of preventing contaminants from penetrating the cutting portion of the tube by the fixing device.

In the groove portion 57, the iron portion 11 of the flexible tube 10 is inserted and fastened. Accordingly, the depth 67 at which the groove portion 57 extends is associated with the insertion length of the iron portion 11, and the depth 67 of the groove portion 57 so that the two configurations can achieve a tight coupling state when fastened. And the insertion length of the convex portions 11 should have appropriate values relative to each other.

In addition, configurations 61 and 63 in which the grooves 57 are equally extended on the left and right sides with respect to the extension portion 54 are coupled to the cutting portions of the flexible tube 10 on the left and right sides of the fixing device 50, respectively. Shows. 6 shows a state in which the fixing device 50 is coupled to the cutting portion 17 of the flexible tube 10.

The cable 20 or the hose is inserted into the first flexible tube 210 configured as described above, and power or water required by the industrial machine is supplied to drive the industrial machine.

On the other hand, according to the working environment, for example, in the case of a welding working environment using a robot, friction of a specific part of the robot and the tube is generated due to the movement of the robot, and as a result, the flexible tube 210 as shown in FIG. 1. Occurs when is broken.

At this time, a large amount of time is required to completely replace the flexible tube 210. In addition, in the working situation, not only the working process time but also various side effects are accompanied. Therefore, there is a need for a method that can easily repair a broken flexible tube in a short time.

Therefore, as illustrated in FIG. 1, when a specific portion of the flexible tube 210 is damaged, the complementary position of the broken flexible tube 210 is cut by a certain amount. Usually, it is preferable to cut so that a predetermined length is included in the left and right sides based on the damaged position.

Then, the second flexible tube 10 is mounted in a complementary position of the first flexible tube 210. At this time, it is preferable that the second flexible tube 10 forms its length as much as the complementary position cut off of the first flexible tube 210.

The second flexible tube 10 has a cutting portion 17 cut at one end in the longitudinal direction. When the cutting part 17 is opened, the inside and outside of the flexible tube 10 are opened.

The second flexible tube 10 of this configuration is subsequently connected to the first flexible tube 210 through the cutting part 17, and the fixing device 50 is fastened to the cutting part 17. At this time, one side of the second flexible tube 10 is inserted into the groove 57 formed on the left side of the fixing device 50 around the cutting portion 17, and the groove formed on the right side of the fixing device 50 is cut. The other side of the second flexible tube 10 is inserted around the portion 17. Of course, at this time, the configuration of the second flexible tube 10 inserted into the groove portion 57 is an iron portion 11.

When fastening the fixing device 50 as shown in FIG. 6 to the cutting portion 17 of the second flexible tube 10 as described above, the bonding process may be performed by a finishing operation using an adhesive or the like.

As described above, when the first flexible tube mounted on the industrial robot is broken, one embodiment of the present invention uses the second flexible tube having one side cut in the longitudinal direction to repair the broken tube simply and quickly. can do.

Therefore, the present invention facilitates the simple repair of the tube without fixing the flexible tube used for being mounted on various industrial machines from the industrial machine, and fastens the cutting portion by using a fixing device, thereby allowing an external Prevents foreign substances from penetrating.

Accordingly, the above detailed description should not be construed as limiting in all respects, but should be considered illustrative. The scope of the invention should be determined by rational interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
