Figure 3 is a perspective view showing a state in which the numbering tube box 10 is coupled to the automatic numbering tube feeder 100 according to the present invention, and Figure 4 is a perspective view showing the configuration of the automatic numbering tube feeder 100. 5 is an example diagram showing the process of coupling the numbering tube box 10 to the automatic numbering tube feeder 100.

The numbering tube automatic feeder 100 according to the present invention is combined with the numbering tube box 10 and supports the numbering tube box 10 in idle rotation by the traction force generated during printing by the printer 40, allowing the operator to run the numbering tube line. Even if (20) is not released by hand, the numbering tube line (20) is smoothly supplied to the printer (40) in the field, allowing printing work to be performed.

As a result, the numbering tube line 20 can be continuously and smoothly supplied to the printer 40 without an operator, preventing unnecessary waste of working manpower, and has the advantage of allowing numbering tube printing to proceed continuously and quickly.

The automatic numbering tube feeder 100 according to the present invention includes a base frame 110 arranged horizontally on the ground, a pair of vertical frames 120 arranged vertically on both sides of the base frame 110, and a pair of vertical frames 120 arranged vertically on both sides of the base frame 110. A pair of axial support brackets 130 coupled to the vertical frame 120, and after being inserted into the axial insertion hole 15 of the numbering tube box 10, both ends can be rotated on the pair of axial support brackets 130. It includes a rotation axis 140 that is mounted.

The base frame 110 is in contact with the ground and the numbering tube box 10 coupled to the rotating shaft 140 rotates idle and when the numbering tube 20' is supplied to the printer 40, it is pulled by the traction force of the printer 40. Support the numbering tube box (10) on the ground to prevent it from falling to the ground.

If the area of the base frame 110 is large, it takes up a lot of space at the work site, so it is better to design the width (W1) and length of the base frame 110 in consideration of the size, weight, and traction force of the numbering tube box 10. desirable.

Here, the base frame 110 is provided by combining a plurality of bars in a rectangular shape, but this is only an example and may be provided in the form of plates of various shapes with a certain area depending on the case.

The vertical frame 120 is vertically coupled to both sides of the base frame 110 at a certain height to form a space between the base frame 110 and the numbering tube box 10 in which the numbering tube box 10 can be rotated. The height of the vertical frame 120 is preferably formed to be higher than the radius of the numbering tube box 10 because it does not interfere with the rotation of the numbering tube box 10. The vertical frame 120 is fixedly coupled to the base frame 110 by a fixing member 121.

A pair of shaft support brackets 130 are provided to face each other on the inside of the vertical frame 120 and rotatably accommodate both ends of the rotation shaft 140 to which the numbering tube box 10 is coupled. The shaft support bracket 130 includes a frame coupling plate 131 fixed to the inside of the vertical frame 120, and an axis receiving member ( 132) and a bracket fixing member 133 that secures the shaft receiving member 132 to the frame coupling plate 131.

The upper part of the shaft receiving member 132 is bent to protrude from the frame coupling plate 131 in a "L" shape, and the lower part is provided with a fixing plate 132b formed parallel to the frame coupling plate 131. As shown in FIG. 4, the shaft receiving member 132 is bent inward with respect to the frame coupling plate 131 and is spaced apart from the frame coupling plate 131 by a certain distance (d). As a result, a space where the rotation axis 140 can be inserted is secured between the frame coupling plate 131 and the frame coupling plate 131.

A shaft insertion groove 132a is cut into the plate surface of the shaft receiving member 132 to correspond to the outer diameter of the rotating shaft 140. The shaft insertion groove 132a has an open upper portion and a semicircular lower portion with a curvature corresponding to the outer diameter of the rotation shaft 140. As a result, the operator can press the rotating shaft 140 from the top to the bottom and easily mount it in the shaft insertion groove 132a.

The rotating shaft 140 is mounted in the shaft insertion groove 132a and rotates idle in the space between the frame coupling plate 131 and the shaft receiving member 132 by the traction force of the printer 40.

As shown in FIG. 5, the rotating shaft 140 is inserted through the shaft insertion hole 15 of the numbering tube box 10, and both ends are mounted on the shaft support bracket 130 so that the numbering tube box 10 can be used as a printer ( It is supported so that it can be rotated by the traction force of 40). The rotating shaft 140 is provided to have an outer diameter corresponding to the inner diameter of the shaft insertion hole 15 and is fitted into the shaft insertion hole 15.

In some cases, if the outer diameter of the rotating shaft 140 is larger than the shaft insertion hole 15, a fixing ring (not shown) that is inserted into the rotating shaft 140 and fixes the position of the shaft insertion hole 15 may be coupled.

Meanwhile, a spacer 150 that adjusts the coupling position of the numbering tube box 10 may be coupled to the rotation axis 140. As shown in FIG. 5, the spacer 150 is coupled to both ends of the rotating shaft 140 to which the numbering tube box 10 is coupled, so that the numbering tube box 10 can be positioned in the center area of the rotating shaft 140. .

In addition, as shown in FIG. 6, when a plurality of numbering tube boxes 10 are coupled side by side to one rotation axis 140, it can be used to space the distance between the plurality of numbering tube boxes 10. .

The process of using the numbering tube automatic feeder 100 according to the present invention having this configuration will be described with reference to FIGS. 3 to 5.

The operator inserts the rotating shaft 140 into the shaft insertion hole 15 of the numbering tube box 10, as shown in FIG. 5. Since the rotating shaft 140 is provided with a length longer than the numbering tube box 10, both ends of the rotating shaft 140 protrude on both sides of the numbering tube box 10 by a certain length.

The worker inserts both ends of the rotating shaft 140 protruding on both sides of the numbering tube box 10 into the shaft insertion groove 132a of the shaft support bracket 130 and places it thereon.

Then, as shown in FIG. 3, the numbering tube line 20 of the numbering tube box 10 is inserted into the printer 40. When the printer 40 is operated in this state, preset characters are printed on the numbering tube line 20, and the numbering tube 20' is cut in half to a preset length and discharged.

In the process of printing the numbering tube 20', when the traction force of the printer 40 is transmitted to the numbering tube box 10, the rotation axis 140 idles inside the shaft support bracket 130 and the numbering tube box 10 is rotated. It rotates automatically.

Accordingly, even if the operator does not rotate the numbering tube box 10 or release the numbering tube line 20 by hand, the numbering tube line 20 can be automatically supplied according to the printing speed of the printer 40.

Meanwhile, Figure 6 is a perspective view showing the configuration of an automatic numbering tube feeder (100a) according to a modified example of the present invention.

The numbering tube automatic feeder 100 described above is combined with only one numbering tube box 10. However, in actual work sites, various types of numbering tubes attached to the wire are required depending on the thickness of the wire.

Accordingly, the numbering tube automatic feeder (100a) according to a modification of the present invention can rotate a plurality of numbering tube boxes (10, 10a, 10b, 10c) with different outer diameters of the numbering tube lines (20, 20a, 20b, 20c). I strongly support it.

For this purpose, the automatic numbering tube feeder (100a) may have a plurality of numbering tube boxes (10, 10a, 10b, and 10c) coupled together side by side on one rotation axis (140). By increasing the length of the rotation axis 140, two or three or more numbering tube boxes (10, 10a, 10b, 10c) can be combined together. At this time, spacers 150 are placed between neighboring numbering tube boxes (10, 10a, 10b, and 10c) to adjust the spacing.

In addition, the vertical frame 120 may be provided with a plurality of axial support brackets 130a and 130a-1 along the height direction to support the numbering tube box 10 in multiple layers. In Figure 6, two numbering tube boxes (10, 10a, 10b, 10c) are each coupled to two rotation axes 140 up and down, but this is only an example, and in some cases, three rotation axes 140 up and down may be provided. It may be possible.

Meanwhile, when supporting a plurality of numbering tube boxes (10, 10a, 10b, 10c) together, if the center of gravity is not aligned when the traction force of the printer 40 is applied, the automatic numbering tube feeder (100a) may fall over. To prevent this, the base frame 110a is provided with an area that can be adjusted.

The base frame 110a includes a frame body 111 coupled to the vertical frame 120, and a movable frame 113 movably coupled to the frame body 111. The moving frame 113 is slidably moved on the frame body 111 and its width (W2) can be adjusted. The operator can adjust the contact area with the ground by adjusting the position of the moving frame 113 according to the number of numbering tube boxes 10 coupled to the rotation axis 140. Additionally, during storage, the width can be minimized to reduce the storage area.

At this time, position fixing legs 115 that can be inserted or protruded are coupled to both sides of the moving frame 113 to ensure that the adjusted position of the moving frame 113 is fixed. A friction member such as rubber is provided on the bottom surface of the position fixing leg 115 to fix the position of the moving frame 113 and improve fixation with the floor.

On the other hand, the numbering tube automatic feeder 100a according to the modified example prevents the rotating shaft 140 from being separated from the shaft insertion groove 132a with an open top when the rotating shaft 140 is rotated, and can rotate more smoothly. It has an axial support bracket (130a, 130a-1) of an improved structure than the axial support bracket 130 of the preferred embodiment.

Figure 7 (a) is an exploded perspective view showing the configuration of the shaft support brackets 130a and 130a-1, and Figure 7 (b) is a rotating shaft 140 on the shaft support brackets 130a and 130a-1. This is a cross-sectional view showing the front cross-sectional structure in this inserted state.

As shown in (a) of FIG. 7, the axle support brackets 130a and 130a-1 have a noise prevention member 134 coupled to the inside of the axle receiving member 132. The noise prevention member 134 is provided to prevent noise from being generated when the rotating shaft 140 is rotated while in contact with the shaft receiving member 132 made of metal.

The noise prevention member 134 may be made of a material that has both strength and elasticity, such as engineering plastic.

A curved surface corresponding to the outer diameter of the rotating shaft 140 is formed on the upper surface of the noise prevention member 134, and a plurality of ball bearings 135 are embedded at regular intervals along the inner wall surface.

As shown in (b) of FIG. 7, the ball bearing 135 contacts the outer peripheral surface of the rotating shaft 140 when the rotating shaft 140 is seated on the noise prevention member 134 and allows the rotating shaft 140 to rotate smoothly. I support it.

Meanwhile, a detachable shaft-disengagement prevention cap 136 is provided on the upper part of the shaft-receiving member 132 to restrict the position of the rotation shaft 140 so that the rotation shaft 140 cannot be separated to the outside. A foldable foldable wing 136c is provided on one side of the axis deviation prevention cap 136, and a fixing protrusion 136d is formed on the inside of the foldable wing 136c.

The fixing protrusion 136d is inserted into the protrusion insertion groove 132c provided on the outer wall of the shaft receiving member 132 to maintain the shaft separation prevention cap 136 and the shaft receiving member 132 in a fixed state. The folding wings 136c are provided to be folded or unfolded along the fold line 136e, allowing the operator to easily couple or separate the axis deviation prevention cap 136.

Meanwhile, at the lower part of the axis departure prevention cap 136, the upper noise prevention member 136a, which is continuous with the noise prevention member 134, is formed with a curved surface of the same curvature, and the rotation axis 140 is formed as shown in (b) of FIG. 7. ) is provided to surround the. In addition, the upper noise prevention member 136a is also provided with an upper ball bearing (136b).

As a result, the rotation axis 140 can rotate more smoothly without noise while its outer circumferential surface is surrounded by the ball bearing 135 and the upper ball bearing 136b.

When numbering tube lines with different outer diameters are required during work, the automatic numbering tube feeder (100a) according to this modification is replaced with the numbering tube box (10) of the numbering tube line with an outer diameter corresponding to the automatic numbering tube feeder (100). There is an advantage in improving work efficiency because the desired numbering tube line (20) among the plurality of numbering tube boxes (10) combined in multiple stages can be used by connecting it to the printer (40).

As seen above, the numbering tube automatic feeder according to the present invention automatically rotates the numbering tube box by the traction force of the printer while coupled to the rotating shaft and supplies the numbering tube line to the printer, so the numbering tube line is supplied without operator intervention. There are advantages to providing it.

Accordingly, the manpower required during work can be reduced and the time required for printing numbering tubes can be shortened.

In addition, there is an advantage in improving work efficiency because a plurality of numbering tube boxes with different outer diameters of the numbering tube line can be combined and used.
