Description

  The present invention relates to a cable packaging box and a cable drawing method that can be smoothly pulled out from an aligned winding bundle of cables in a horizontal direction with respect to the bundle without tangling the cables.

  Conventionally, when a cable is pulled out from an aligned winding bundle of cables, it can be pulled out only in a direction perpendicular to the bundle, that is, in the upper part. Further, when the bundle is used while being packed in a box, the boxes cannot be stacked because they can be pulled out only from the upper part.

  On the other hand, when pulling out the cable from the lateral surface, there is a turntable method in which the cable is wound around the reel or drum and the reel or drum is rotated, but the reel or drum around which the cable is wound is rotated. There are problems that a force is required to pull out the cable and that the reel or the drum itself is expensive.

  Further, there is a method in which the cables are bundled in an 8-shaped shape and drawn out from the inside of the bundle. The figure-eight winding allows the cable to be pulled out lightly from the side, but special equipment is required to bundle the cables, and the outer diameter of the bundle increases when wound several hundred meters, and becomes bulky when placed in a box. There is a problem.

As described in Patent Document 1, it is difficult to twist a wire cable drawn from inside, it is easy to pull out, and in addition, the invention of a compact wire cable package that can be stacked in multiple stages in the vertical direction and is easy to handle. It has been published.
JP 2000-007068 A

  However, the invention described in Patent Document 1 requires that the cable be wound in a special way called winding.

  Therefore, the present invention can be used by a method of pulling out a cable from the aligned winding bundle, which is the most common bundling method, in a horizontal direction, and can be pulled out sequentially without being entangled. It is aimed to provide a simple cable packaging box.

  In order to solve the above-mentioned problems, the present invention accommodates an aligned winding bundle in which a single cable is concentrically aligned and wound several times in a box body having a front hole on the front surface. It is characterized by placing an inner lid attached with a pulp mold having a through-hole having a diameter smaller than the inner diameter, folding protrusions on the left and right ends of the upper lid of the box body, and grooves on the left and right side lower portions of the box body, The plurality of box bodies are configured as a cable packaging box that can be stacked by fitting the folding protrusions of the lower box body into the grooves of the upper box body.

  Since this invention is the above structure, the following effects are acquired. First, even the most common winding method, an aligned winding bundle, can be pulled out with a light force in the horizontal direction without being entangled.

  Secondly, since the aligned winding is sufficient, it is not necessary for the cable manufacturer to introduce special equipment for winding the cable, and the initial cost is not required.

  Thirdly, since an aligned winding bundle is sufficient, the height of the bundle can be lowered, and the height of the box can also be lowered, so that it is easy to carry without being bulky.

  Fourth, since the height of the box can be reduced, the load can be dispersed even if the boxes are stacked several times, so that the box is not easily crushed.

  Fifth, since the cable can be pulled out from the front of the box, it can be used with the boxes stacked. It should be noted that the stacked boxes are not easily collapsed by fitting the folding protrusions into the grooves.

  Sixth, it is possible to pull out the cable from the top of the bundle by punching the perforation on the top lid of the box.

  The present invention relates to a cable drawing method capable of sequentially drawing cables from an aligned winding bundle, which is the most common bundling method, in a horizontal direction and without being entangled, and a cable that can be used even when stacked. For the purpose of providing a packaging box, a box body having a front hole on the front side is used to store an aligned bundle in which a single cable is concentrically arranged and wound in several stages, and an inner diameter is placed on the aligned winding bundle. A plurality of boxes, characterized in that an inner lid fitted with a pulp mold having a through-hole with a small diameter is placed, folding protrusions are provided at the left and right ends of the upper lid of the box body, and grooves are provided at the lower left and right side surfaces of the box body. The main body is realized by configuring a cable packaging box that can be stacked by fitting the folding protrusions of the lower box body into the grooves of the upper box body.

  Below, based on an accompanying drawing, the cable packing box which is the present invention is explained in detail. FIG. 1 is a perspective view of a cable packing box according to the present invention, FIG. 2 is a view in which an upper cover of the cable packing box according to the present invention is opened, and FIG. It is the figure which took out the lid | cover.

  The cable packing box 1 accommodates an aligned bundle 5a in which a single cable 5 is arranged concentrically and wound several times in a box body 2 having a front hole 2k on the front surface, and an inner diameter is placed on the aligned bundle 5a. An inner lid 3 to which a pulp mold 4 having a through-hole 4c having a smaller diameter is attached is placed.

  The box body 2 is a flat rectangular parallelepiped hollow box made of a light material such as cardboard. The box body 2 can open and close the upper lid 2a on the upper surface, and can accommodate the cable 5 that is arranged concentrically and wound several times inside.

  The height of the box main body 2 depends on the outer diameter and the winding amount of the cable 5 accommodated therein, but it is not necessary to increase the height of the bundle by adjusting both. If the height of the boxes can be kept low, the center of gravity when the boxes are stacked can be kept low, and more boxes can be stacked.

  The upper lid 2 a is a lid for the box body 2. The upper lid 2a is connected to the rear surface 2d on the back side, and opens and closes by lifting the front side. Further, a projection 2i is provided on the front side of the upper lid 2a, and the cable packaging box 1 is closed by being fitted into the insertion port 2j of the front surface 2b.

  Further, the upper lid 2a is provided with a perforation 2f for an upper hole and a perforation of a folding projection 2g. When the perforation 2f for the upper hole is cut, the upper hole 2l is vacant, and the folding protrusion 2g can be raised by cutting the perforation.

  The front surface 2 b is a surface on the near side of the box body 2. An insertion port 2j is opened in the upper part of the front surface 2b, and the protrusion 2i of the upper lid 2a can be inserted. Further, the front surface 2b has a front hole perforation 2e, and when the perforation is cut, the hole 2k is opened.

  The side surface 2 c is a surface on both the left and right sides of the box body 2. A groove perforation 2h is provided below the side surface 2c. When the perforation of the groove perforation 2h is cut out, a groove 2m is formed, and the folding projection 2g of another cable packing box 1 can be fitted and connected vertically.

  The back surface 2 d is a back surface of the box body 2. The back surface 2d has a lower end connected to the bottom surface and an upper end connected to the upper lid 2a. The cable packaging box 1 can be opened and closed by rotating the upper lid 2a.

  The front hole perforation 2e, the upper hole perforation 2f, and the groove perforation 2h are in a closed state at the time of shipment, and the folding protrusion 2g is in a folded state. When using, open perforations if necessary. The groove perforations 2h may be left open from the beginning.

  The protrusion 2i is a rectangular member provided on the near side of the upper lid 2a, and the insertion port 2j has a slight thickness on the front surface 2b and a linear groove on the upper surface. The projection 2i and the insertion port 2j may be located at one center or two on the left and right sides, but the projection 2i and the insertion port 2j are aligned with each other.

  The hole 2k is a circular hole through which the cable 5 passes, and has a front hole perforation 2e. The hole 2k may be formed in a U shape from the upper part of the front surface 2b. However, since the hole 2k may become an obstacle when the upper lid 2a is closed, it is preferable to form a circle.

  The inner lid 3 is a plate such as a substantially square cardboard that is slightly smaller than the upper lid 2a. The inner lid 3 is a member independent of the box body 2 and is placed on a bundle of cables 5 placed in the box body 2. A hole is made near the center of the inner lid 3 and the pulp mold 4 is attached.

  The pulp mold 4 is a member in which recycled paper or the like is melted with water and formed into a tubular shape to evaporate moisture, and a hole penetrates the cable 5 from the lower side to the upper side of the inner lid 3. Friction is generated by the drawn cable 5 coming into contact with the lower part of the pulp mold 4, and an extra load that breaks the bundle of cables 5 can be dispersed.

  The cable 5 is an aligned wound bundle 5 a in which a single electric wire or the like is concentrically arranged and wound several times to form a bundle, and is housed in the box body 2. The cable 5 is preferably wound by a general winding method that does not require special equipment. Further, it may be right-handed or left-handed.

  The aligned winding bundle 5a can be pulled out of the bundle and smoothly pulled out by pulling the tip 5c of the cable 5 from the inner diameter of the central cavity 5b. If the cable 5 is separated from the aligned winding 5a and falls into the cavity 5b, the cable 5 is entangled. Therefore, the tension when pulling the cable 5 is suppressed, and the fall into the cavity 5b is prevented as much as possible.

  FIG. 4 is a diagram showing a state in which the cable is passed through the inner lid of the cable packaging box according to the present invention, and FIG. 5 is a diagram showing a state in which the cable is passed through the hole of the cable packaging box according to the present invention. .

  The cable packaging box 1 can be used with the cable 5 stored. The box body 2 is once opened from the state at the time of shipment, and the tip of the cable 5 is passed through the pulp mold 4 of the inner lid 3 and taken out above the inner lid 3. In the state at the time of shipment, the cable 5 may be extended to the upper side of the inner lid 3.

  The front hole perforation 2e on the front surface 2b of the box body 2 is cut out to make a hole 2k, and the tip of the cable 5 is taken out from the inside of the box body 2 to the outside. The upper lid 2a of the box body 2 is closed, and the cable 5 is pulled out from the hole 2k of the box body 2 as much as necessary.

  FIG. 6 is a plan view of the inner lid of the cable packaging box according to the present invention, and FIG. 7 is a front view of the inner lid of the cable packaging box according to the present invention.

  The lid body 3a of the inner lid 3 is a square plate made of a light material such as corrugated cardboard, like the box body 2, and may be chamfered at four corners. Moreover, you may round. A circular hole is formed in the center of the lid body 3a or a position slightly shifted from the center, and the pulp mold 4 is fitted.

  The pipe 4a of the pulp mold 4 is passed from the upper side to the hole of the inner lid 3, and the edge 4b of the pulp mold 4 is attached around the hole of the inner lid 3, so that the pulp mold 4 does not come off from the inner lid 3. Fix it.

  In addition, the pipe 4a of the pulp mold 4 protruding downward from the inner lid 3 also has an effect of preventing the remaining cable 5 from being pulled out from the lower portion of the pulp mold 4 when the remaining amount of the cable 5 decreases. .

  Further, when the cable 5 is pulled out, the lid body 3a of the inner lid 3 is placed on the cable 5, so that the cable 5 drifts in the space generated in the box body 2 when the cable 5 is reduced. Since it can prevent, the cable 5 does not get tangled.

  Since the inner lid 3 is placed on the bundle of cables 5, when the remaining amount of the cable 5 decreases, it falls off due to its own weight. Even if the number of the cables 5 is reduced, the cable 5 can be pressed, and a stable action can be always generated.

  With respect to the cable 5 to be pulled out, a slight load is applied by the pulp mold 4 to adjust the pulling tension. Since no force is suddenly applied to the cable 5, there is an effect of preventing the bundle of cables 5 from being broken.

  FIG. 8 is a diagram in which the pulp mold is removed from the inner lid of the cable packaging box according to the present invention, and FIG. 9 is a diagram illustrating a situation in which the cable of the cable packaging box according to the present invention is pulled out.

  The pipe 4a of the pulp mold 4 is a tubular member having a short length, and a ring-shaped edge 4b is continuously provided outwardly on the upper circumference. Moreover, the pipe 4a has a through hole 4c that passes from the upper side to the lower side.

  In FIG. 9, reference numeral 6 denotes a case where the position where the bundle 6c of the cables 5 in the box body 2 can be unwound when the cable 5 is pulled out in the pulling direction 6b, and reference numeral 6a denotes the cable 5 in the pulling direction 6b. This is the case where the position where the bundle 6c of the cables 5 in the box body 2 can be unwound when being pulled out.

  The cable drawing method is characterized in that the tip 5c of the cable 5 taken out from the inside of the aligned winding bundle 5a is passed from the lower side to the upper side of the through hole 4c of the pulp mold 4 and taken out from the front hole 2k of the box body 2. .

  Further, the cable drawing method is characterized in that the tension applied to the cable 5 is reduced by bringing the cable 5 unwound from the aligned winding bundle 5a into contact with the lower end of the pipe 4a of the pulp mold 4.

  In either case 6 in the back or 6a in the front, by controlling the path of the cable 5 with the pulp mold 4, the cable 5 can be pulled out smoothly without being entangled inside the cable packaging box 1. it can.

  Since the cable 5 comes into contact with the lower part of the pipe 4a of the pulp mold 4 and friction is generated, the force for pulling out the cable 5 is suppressed. Since the load applied to the bundle 6c of the cable 5 is reduced, the bundle 6c does not collapse and the cable 5 is not entangled.

  The cable 5 is unwound from the bundle 6c, but the pipe 4a of the pulp mold 4 is also circular, so that the cable 5 is always in contact with the lower part of the pipe 4a, and the cable 5 is pulled out stably and smoothly. be able to.

  As the cable 5 is pulled out, the height of the bundle 6c gradually decreases. However, since the inner lid 3 is only placed on the bundle 6c, if the height of the bundle 6c is lowered, the inner lid 3 is also lowered. The withdrawal status is maintained.

  FIG. 10 is a diagram in which the position of the pulp mold of the cable packaging box according to the present invention is adjusted, and FIG. 11 is a table showing the result of the position adjustment of the pulp mold of the cable packaging box according to the present invention.

  The position of the pulp mold 4 may be the center 3b of the lid main body 3a of the inner lid 3, but it may be easier to pull out if it is slightly shifted from the center 3b. Table 7 shows the cable drawing results when the conditions are changed.

  In Table 7, the height is the height of the pipe 4 a of the pulp mold 4, the position is the position of the pulp mold 4 in the inner lid 3, the winding direction is the direction in which the cable 5 is wound, and the amount of winding is the number of winding steps of the cable 5 (increase / decrease) ).

  When the height is 20 mm, the position is the center, the winding direction is right, and the winding amount is large, the cable drawing result is relatively smooth.

  When the height is 20 millimeters, the position is the center, the winding direction is left, and the winding amount is large, the result of cable drawing is that the cable falls inside the bundle and tries to come out at a time after it has accumulated a little. Furthermore, when it is pulled out, it becomes spiral inside the bundle, and it becomes difficult to twist and pull out.

  When the height is 20 mm, the position is 50 mm from the center to the back, the winding direction is right, and the winding amount is large, the cable drawing result is that when the cable 5 on the front side tends to stagnate and goes to the back side Suddenly released.

  When the height is 20 millimeters, the position is 50 millimeters from the center, the winding direction is right, and the winding amount is large, the cable drawing result is that the cable 5 on the near side becomes steep and slightly heavier.

  When the height is 20 mm, the position is 25 mm from the center to the back, the winding direction is right, and the winding amount is small, the cable pulling result is that the cable 5 on the front side becomes steep and is caught and lifts the inner lid 3 Will be slightly heavier.

  When the height is 20 millimeters, the position is 25 millimeters from the center, the winding direction is right, and the winding amount is small, the result of drawing the cable is slightly heavy because the inner lid 3 is lifted.

  When the height is 20 millimeters, the position is 25 millimeters from the center, 30 millimeters to the left, the winding direction is right, and the winding amount is large, the cable drawing result is drawn smoothly.

  If the height is 20 millimeters, the position is 25 millimeters from the center, 30 millimeters to the left, the winding direction is right, and the winding amount is small, the result of pulling out the cable is that the inner lid 3 is lifted and the cable 5 is pressed down. Disappear. A gap is generated between the pulp mold 4 and the box bottom, and the cable 5 is spirally entangled.

  When the height is 30 mm, the position is 25 mm forward from the center, 20 mm to the left, the winding direction is right, and the winding amount is small, the cable drawing result is drawn smoothly.

  When the height is 30 mm, the position is 25 mm forward from the center, 20 mm to the left, the winding direction is right, and the winding amount is large, the cable drawing result is drawn smoothly.

  In addition, although the cable 5 is entangled or not entangled, it depends on the winding direction of the cable 5 and the winding direction of the bundle winder, but the cable 5 is placed in the opposite direction to the twisting direction or the collective twisting direction. Is preferred.

  As a result, if the height of the pulp mold 4 is about 20 to 30 millimeters and the position is shifted about 25 millimeters from the center to the front and about 20 to 30 millimeters to the left, the cable 5 can be pulled out more smoothly.
