Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a packing method and a packing device for a tail cord suspended between an elevator cargo and a connection box provided on the side wall of a shaft.

[Conventional technology]

A tail cord has a cord body having a structure in which a large number of thin wire cores are arranged in parallel and covered with a flexible flat sheath, and the cord is equipped with connectors at both ends.

However, since the tail cord has a directionality in bending, the tail cord is wound into a spiral using the flat surface thereof before shipping.

[Problem to be solved by the invention]

For tail codes shipped as above,
Conventionally, a spirally wound tail cord was generally drawn out from the winding start end on the center side.

However, when the above-mentioned withdrawal was carried out, the tail cord itself was twisted each time the nutrients were drawn out. This twisting problem has been corrected by rotating the cord itself with the pull-out end of the cord as the free end, but since the cord is installed by hanging from the elevator room into the shaft, Each time the shaft is rotated, the terminal connector located at the hanging end side is swung around and collides with the side wall of the shaft, potentially causing damage.

Further, since the conductor of the tail cord is constructed by twisting thin wires to improve flexibility, there is a risk that the conductor may easily break due to such twisting.

On the other hand, for ordinary flat cords, etc., a drum is used which has a winding drum with flanges at both ends, and the drum is wound spirally onto the drum with the flat surface participating. A zero-wrap flat cord can be used because it can be pulled out from the end of the winding without twisting the cord itself.

However, this drum does not take any special consideration to protect the terminal connector, so in order to wind up the cord with a connector, a corresponding special drum is required, which increases production costs. Since it is usually made of metal, it is not easy to handle, and it requires a relatively large installation area and work space. Not only is it difficult to carry it into a narrow elevator room, but even if it is possible to carry it in, it is difficult for workers to move. There was a possibility that it would become impossible to install the cable.

Furthermore, regarding the terminal connector of the tail cord,
Various types are required depending on the usage, and it may be necessary to take out the packaged item again and replace the terminal connector, but conventional packaging equipment and reeling equipment do not allow such problems. No device adapted to the tail cord has been proposed.

The present invention has been made in view of the above circumstances, and
One purpose is to provide a packing method for a tail cord that can be packaged economically and compactly without increasing manufacturing costs, and that can also be easily adapted to the unwinding of the cord. .

In addition, we have developed a packing device for tail cords that is lightweight and easy to handle without taking up much installation space, and that allows for smooth unwinding without damaging the terminal connector or twisting the cord itself. There is another purpose in providing this. It is another object of the present invention to provide a packaging device of this type that allows easy replacement of the terminal connector of a once-packed tail cord.

[Means and actions to solve the problem]

In the tail cord packaging method provided by the present invention, the tail cord is spirally wound around the outer periphery of a donut-shaped core made of corrugated cardboard to form a cord winding unit, and this cord winding unit is wrapped around a rectangular frame-shaped corrugated cardboard. The core is housed in a box, and a shaft is disposed through the center of a wide rectangular piece of the corrugated box to pivotally support the core.

By doing this, it can be easily packed using cardboard and shafts that are easier to cut than metal drums.
Moreover, it can be packed in a thin box, making it more compact. In addition, the tail cord is pre-wound around a donut-shaped winding core and is stored in a cardboard box with the cord winding unit supported by a shaft, so the tail cord can be placed at the end of the winding while the cardboard box is still in place. It allows you to extract from.

Furthermore, the packaging device provided by the present invention includes a winding core formed in a donut shape of corrugated cardboard and having a groove formed on the outer periphery for accommodating the winding start end of the tail cord, and a rectangular frame shape containing the winding core. The cardboard box is equipped with a shaft that penetrates the side wall of the cardboard box and is pivoted by skewering the core in the cardboard box, and the cardboard box is arranged so that the two cardboard boxes are arranged vertically along the cut end where the corrugated fault appears. When the left and right side edges are folded and overlapped with each other and stitched, two narrow side walls are formed, and a wide side wall through which the shaft is passed laterally is formed between the narrow side walls and facing each other. The lower edge of one corrugated cardboard and the upper edge of the other corrugated cardboard are each folded to form a lid piece, and includes means for temporarily fixing the winding end of the tail cord to the inside of one of the lid pieces. It's because I let it happen.

In this way, the tail cord is housed in a thin cardboard box that can be used while standing upright, making it lightweight and easy to handle without taking up much installation space. Also,
By storing the terminal connector on the winding start side in the groove of the cardboard winding core, the tail cord can be prevented from being unwound due to the spiral of the cord itself, and the end of one winding end can also be temporarily secured. Since it is fixed by the means, it is prevented from accidentally moving, thereby preventing damage caused by excessive external force being applied to the terminal connector and its core connection portion.

Furthermore, since the winding core of the tail cord is supported by the shaft, it can be smoothly pulled out from the end of the winding without twisting.

Additionally, a cardboard box is made up of two cardboard boxes that are assembled into a rectangular frame shape, but because they are overlapped and stitched on the narrow side walls, the studs used for stitching press strongly against or rub against the tail cord. This can reduce the risk.

In addition, when two cardboard boxes are cut with the waveform faults facing up and down, the upper and lower sides form the cord outlet, and the shaft body serving as the rotation shaft is arranged horizontally through the wide side wall. It is possible to prevent the cardboard box from deforming due to the load of the tail cord at the body-penetrating portion and the shearing force received when the cord is pulled out.

The temporary fixing means may be one for adhering the terminal including the connector of the tail cord to the lid piece using double-sided adhesive tape,
Furthermore, the protector may have a structure that allows the terminal connector to be accommodated in a shape that fits in the extra space within the cardboard box that accommodates the cord wrapping unit.

Therefore, the temporary fixing means is preferable! For Mr. S, there is an inner lid that covers the opening by straddling the edges of two narrow side walls of the cardboard box, and the end of the tail cord is attached to the inner lid, and these are both held together. It is best to use a holder that includes a holder.

The lid piece is preferably bent in an abbreviated shape, and preferably has a structure in which a slit is cut from the edge at the intermediate fold in a portion close to the winding end of the tail cord. By doing so, an appropriate opening is formed by raising the lid piece from the edge by the length of the slit, making it possible to pull out the tail cord without dismantling the cardboard box.

According to the present invention, the cardboard box can also be manufactured from a single piece of cardboard.

In other words, by making two parallel bends on a single piece of cardboard at the position where the width is doubled, one narrow side wall and up to two wide side walls connected to this are formed, and then those two wide side walls are formed. By bending the extended end side edges of the side walls, overlapping each other, and stitching them, another narrow side wall opposite to the above-mentioned two narrow side walls is formed, and lid pieces are extended from the upper and lower both edges of the wide side wall. A horizontal hole is formed in each center of the two wide side walls integrally extending from the narrow side wall formed by intermediate bending, through which the shaft body is disposed.

By doing this, the number of cardboard sheets can be reduced, and since the opposing wide side walls are connected together by one narrow side wall, there is no need to worry about misalignment, and the horizontal hole that passes through the shaft body can be Centering can be performed reliably.

The shaft is preferably a paper tube, which has high strength and is lightweight. However, in addition to this, a wooden pole or a plastic body such as a short pipe may also be used.

Paper tubes and wooden posts have poor elasticity, so if they just penetrate the side holes of a cardboard box, they may fall off. Therefore,
If a paper tube or the like is used, it is desirable to add an appropriate means to prevent it from being pulled out.

In the case of a plastic molded body, appropriate elasticity is obtained, so that it can be fixed to a cardboard box by inserting the molded rod with elastic deformation. However, instead of using elasticity, it is also possible to provide a bolt/Nand structure to itself and assemble it by screwing, or it may be separately tightened and fixed with a bolt/Nand.

〔Example〕

FIG. 1 is an explanatory diagram showing the procedure for packing the tail cord, and FIG. 2 shows the state in which the packing is completed.

As is clear from this embodiment, the winding core 1, the cardboard box 2, and the shaft body 3 are used to package the tail cord 4.

The winding core 1 is formed by laminating and integrating a plurality of disk-shaped pieces of cardboard cut into a donut shape.
In particular, as shown in FIGS. 3(A) and 3(B), a notch 11 is formed on the periphery to accommodate the terminal connector of the tail cord. As shown in FIG. 1, the tail cord 4 has a winding core l formed as described above.
The cord is wound in a spiral and is packed in advance as a cord winding unit 5. A terminal connector 41 provided at the winding start end of the tail cord 4 is accommodated in a drop-in manner in the groove 11 of the winding core 1, thereby preventing unwinding from occurring when the tail cord 4 is wound around the vortex S.

As clearly shown in FIG. 4, the cardboard box 2 is a combination of two cardboard boxes 2122 having a two-layer structure, and each cardboard box 2122 has left and right side edges when the cut end where the wave-shaped fault appears is turned up and down. are respectively folded to polymerize the opposing folded edges 21a and 22a, 21b and 22b on each side, and the metal chain 2
By performing the stitching by driving No. 3, two narrow side walls 24, 24 are formed, and wide side walls 25, 25 are formed spaced apart and facing each other between the narrow side walls. At the top, the upper edge of one of the cardboard boxes 22 is bent into an oval shape to form a lid piece 22c.

Although not particularly shown, a lid piece similar to the lid piece 22c is also provided on the lower edge of the other cardboard 21.

Either one of the upper or lower lid pieces, for example, when the upper lid piece 22C is used as the cord insertion/removal side as in this embodiment, the other side, that is, the lower lid piece, is configured to close the lower opening. The roof shall be installed and the seams shall be adhesively fixed with adhesive tape, etc. as appropriate.

In the upper lid piece 22c selected as the cord entry/exit opening, a slit 22d is formed at an intermediate bent portion of the L-shape over an appropriate length from the edge, and is used to form a cord exit opening, which will be described later. used.

The above-described cord wrapping unit 5 is inserted into such a cardboard box 2 from the upper opening and housed therein.

Therefore, it goes without saying that the narrow width of the cardboard box 2 corresponds to the wide dimension of the tail cord.
The size is made to correspond to the winding diameter of the cord winding unit 5.

The shaft body 3 is made of a paper tube and has a length comparable to the narrow width of the cardboard box 2, and the wide side wall 25.2 of the cardboard box 2.
By passing through a horizontal hole 25a bored in the center of the frame 5, it is disposed horizontally between the wide side walls 25° and 25 degrees. The shaft body 3 arranged in this way has a winding core l
The core l is inserted through the central hole 12 of the cardboard box 2, thereby pivotally supporting the winding core l within the cardboard box 2. Therefore, the shaft body 3 receives the weight of the winding core l and the tail cord 4 wound thereon, and causes the wide side walls 25, 25 of the corrugated box 2 to share the load.

As mentioned above, the wide side wall 25.25 has a two-layer corrugated cardboard structure that is exposed on the cord pull-out side, so it can withstand the weight of the tail cord 4, etc. and the shearing force applied when the cord is pulled out. This makes it possible to prevent problems such as deformation of the horizontal hole 25a.

Note that since the paper tube 3 has poor elasticity, there is a possibility that the paper tube 3 may be pulled out of the cardboard box 2. Therefore, a seal-type fixing means that covers the end face of the paper tube 3 and is fixed to the wide side wall 2525 of the cardboard box 2 may be included.

The cardboard box 2 which accommodates and pivots the cord winding unit 5 as described above is covered with the upper lid piece 22C as shown in FIG. 2, and the packaging is completed. In addition, it is preferable that the installed lid piece 22c is adhesively fixed with adhesive tape or the like so that it does not open easily.

Since the tail cord 4 has a connector 42 at the end of its winding, if it is allowed to move freely within the cardboard box 2, it will not connect to the connector 42 due to shocks and vibrations received during transportation. The exposed core end may cause breakage, breakage, or poor connection. Therefore, as shown in FIG. 5, it is desirable to provide means 6 on the inside of the lid piece 22C for temporarily fixing the winding end of the tail cord.

This temporary fixing means 6 includes an inner lid 61 that covers the opening by being placed between the edges of the two narrow side walls 24, 24 of the cardboard box 2, and a winding end of the tail cord 4 on the inner lid. It consists of a holder 62 that holds both of them in the attached state, and both of these are preferably made of corrugated cardboard.

The tail cord 4 that has been packed as described above is shipped while still being wrapped in the cardboard box 2, and is then carried into the elevator room for installation.

When installing the cable, the tail cord 4 is centered around the shaft body 3 by raising the lid piece 22c outward by the distance of the slit 22d from one end of the lid piece 22c to form a lower cord drawer as shown in FIG. As the winding core 1 rotates, it can be pulled out from the end of the winding, and then hung down from the elevator room to be used for laying.

When the paper tube 2 is used as the shaft body 3, there is a possibility that the paper tube 2 will come out of the cardboard box as described above, so it is desirable to add a suitable means for preventing the paper tube from being pulled out. FIGS. 7 and 8 show a stopping means at the rear of the shaft body and a structure for incorporating the same, which met this demand.

The stopper 7 for preventing removal is made of hard plastic and includes a tubular insertion portion 71 and a flange portion 72 integrally provided on the rear end side. The insertion part 71 has an outer diameter slightly larger than the inner diameter of the paper tube as the shaft body 3, and is tightly fitted to the paper tube, and has a slightly reduced diameter at the tip to facilitate press-fitting into the paper tube. I'm trying to do it. According to such a stopper 7, the insertion part 71 is press-fitted into the paper tube that becomes the shaft body 3 from its end,
By pushing in until the flange 72 is applied to the outer surface of the wide side wall of the cardboard box, the paper tube is firmly suspended between the wide side walls 25, 25, and a predetermined pull-out prevention is achieved.

Note that a linear white line extending in the insertion direction is formed on the surface of the insertion portion 71 to improve the grip on the inner surface of the paper tube.

FIG. 9 shows another embodiment of the cardboard box 2. The cardboard box 2 of this embodiment is made by forming two parallel folds in the middle of a single piece of cardboard 26, and folding the cardboard box 26 at each fold. By bending at right angles, a narrow side wall 24 is formed between the two folds, and two wide side walls 25, 25 extend from both edges of the narrow side wall via the folds. The extended side edges of the two wide side walls 25.25 are
A crease is made at an appropriate position so as to obtain a width corresponding to the narrow side wall 25, and the two bent ends 26a26a formed by the crease are overlapped with each other and stitched with metal silver 23. A second narrow side wall 24 is formed.

The cardboard box 2 formed into a rectangular frame shape as described above further has a lid piece 26b extending from the upper edge of one of the wide side walls 25, 25, similar to the above-mentioned embodiment. Although not particularly illustrated, a lid piece is also formed on the lower edge of one of the wide side walls 25, 25, as in the embodiment described above.

A horizontal hole 25a is formed in the center of the wide side wall 25.25, as shown in one side wall, and is used for penetrating the shaft.

According to the corrugated box of this embodiment, the stiffening part only needs to be placed on one narrow side wall, and the other narrow side wall is integrated with the wide side wall, so that it does not easily lose its shape. Since the horizontal holes 25a are bored in one piece of cardboard, it is easy to center the horizontal holes in both wide side walls after assembly.

FIG. 10 shows an application example of the shaft body 3 and its mounting structure. That is, the shaft body 3 consists of one flanged tube 31 and another flanged tube 32 inserted into this. It is also made of hard plastic.

As shown in FIGS. 11(a) and 11(b), the inner insertion side flanged tube 32 has a shaft tube portion 33 divided into two parts, and the separation width increases toward the tip.

At the tip, there is a split element 33 as shown in (a)
Either a and 33a are formed to expand outward in the shape of *13It, or (b) a small protrusion 33c is formed on the outer periphery of each of the straight two-split elements 33b and 33b as shown in the figure. .

According to such a shaft body 3, first, the flanged tube 3 serving as the outer shaft is
Insert the pipe from one wide side wall 25 (left side) to bridge the pipes on both sides 25.25, while inserting the flanged pipe 32, which becomes the inner sheath, from the outside of the other wide side wall 25 (right side), and insert the pipe from the outside of the other wide side wall 25 (right side). The own dividing element 3 is attached to the shaft tube portion 33 of the flanged tube 31.
Insert with 3a, 33a or 33b, 33b narrowed.

By inserting the flange until it hits the side wall 25, the IIIK-shaped portion or small protrusion 33c at the tip protrudes outside the other side wall, and the divided elements 33a, 33a or 33b, 33b, which have been narrowed accordingly, are It is expanded by its own elastic restoring force, so that the tip is locked to the flange of the flanged tube 31 on the other side wall, and the shaft body 3 is assembled in a predetermined manner to prevent it from being pulled out.

This shaft body can be assembled by pulling out the inserted flanged tube 32 and then pulling out the flanged tube 31 of the outer shaft, thereby removing the cord wrapping unit 5 housed in the cardboard box (see FIG. 1).
to be removed from the cardboard box. This is -
It is used when the terminal connectors 41 and 42 of the once packed tail cord are replaced due to specification changes, etc.

FIG. 12 and FIG. 13 show two further embodiments of the insertable and removable shaft body and its mounting structure.

In the embodiment shown in FIG. 12, the flanged cylinder 34 is connected to one wide side wall 2
5 (left side) and horizontally arranged on both wide side walls 25 and 25 tubes, and a disc-shaped seat body 35 is applied from the other wide side wall 25 (right side), and these flanged tubes 34 and seat body 35 By passing a bolt 36 through the hole and tightening it with a nut 37, a predetermined attachment and fixation can be achieved. By disassembling the bolt 36 and the NAND 37, it is possible to remove the shaft body.

In the embodiment shown in FIG. 13, the female threaded pipe 38 with a flange is inserted from one wide side wall 25 (left side) and
By reinforcing the pipe, inserting the flanged male pipe 39 from the other wide side wall (right side) and screwing it into the female thread pipe 38, it is assembled into a cardboard box as a predetermined shaft body 3. By releasing the threaded connection between both tubes, it is possible to remove the shaft as a shaft.
