Description

Description: TECHNICAL FIELD The present invention relates to a packing device for a tail cord suspended between an elevator cargo and a connection box provided on a side wall of a shaft.

[Conventional technology]

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

Since the tail cord has directionality with respect to bending, the tail cord is wound in a spiral shape with the flat surface as the winding surface for shipping.

[Problems to be Solved by the Invention]

For the tail cords shipped as above,
Conventionally, generally, a spiral tail cord has been drawn out from the winding start end portion on the center side thereof and extended.

However, when the drawer is pulled out as described above, the tail cord itself is twisted every time one reel is reeled out. This twist was corrected by rotating the cord itself with the pull-out end side of the cord as the free end, but since the cord is laid down from the elevator room into the shaft, Each time the rotation is performed, the terminal connector located on the side of the hanging end may be swung and collide with the side wall of the shaft to be damaged.

Further, since the tail cord has a conductor formed by twisting fine wires in order to improve flexibility, there is a fear that the conductor is easily broken by the addition of the twist.

On the other hand, in a normal flat cord or the like, a drum including a winding drum having flanges at both ends is used, and a flat surface is used as a winding surface to wind the spiral winding on the winding drum. Was there. Since the twisted flat cord is not added to the cord itself by pulling it from the winding end, it can be used.

However, since the drum does not take special care to protect the terminal connector, in order to wind up the cord with the connector, a special drum corresponding to it is required, which increases the production cost, and Since it is usually made of metal, it is not easy to handle, it requires a relatively large installation area and work space, and it is difficult to carry in a small elevator room. There was a possibility that it would not be possible to get rid of it and it would be impossible to lay it.

The present invention has been made in view of the above circumstances, is lightweight, can be easily handled without taking up a large installation space, and can be smoothly delivered without damaging the terminal connector and twisting the cord itself. It is an object of the present invention to provide a packaging device for a tail cord that enables the above.

[Means and actions for solving the problem]

The tail cord packing device provided by the present invention packs a spirally wound tail cord having terminal connectors at both ends, and is formed of corrugated cardboard in a donut shape and the tail cord is wrapped around the outer circumference. A core provided with a groove for accommodating the terminal connector on the starting end side, a rectangular frame-shaped cardboard box containing the core, and a core penetrating a side wall of the cardboard box and inside the cardboard box. The cardboard box is a skewered shaft supporting the corrugated cardboard box. Two narrow sidewalls are formed, and wide sidewalls that laterally penetrate the shaft are formed between the narrow sidewalls so as to face each other. And a lid member by bending the edge of each is to them the ends and the terminal connector end of the winding of the tail cord inside of the lid pieces one of was included the temporary fixing to unit.

In this way, the tail cord is stored in a thin cardboard box that can be leaned against and leaned against, so that the tail cord can be handled easily without taking up a large installation space. Also,
By storing the terminal connector on the winding start side in the groove of the core made of corrugated cardboard, the tail cord can be prevented from receiving winding pressure due to the spiral of the cord itself, and one winding end can also be temporarily fixed. Since it is fixed by this, it can be prevented from being inadvertently moved, so that it is possible to prevent the terminal connector and its core connection portion from being injured by an unreasonable external force.

Further, since the winding core of the tail cord is supported by the shaft body, it can be smoothly pulled out without being twisted from the winding end side.

In addition, the corrugated cardboard box is formed by combining two corrugated cardboards into a rectangular frame shape, but since the narrow side walls are superposed and stitched, the tack used for the stitch pushes or rubs against the tail cord strongly. That can reduce the risk.

Moreover, when the corrugated faults of the two corrugated cardboards are placed up and down, the cord outlets are formed on the upper and lower sides, and the shaft body as the rotating shaft is laterally arranged on the wide side wall. It is possible to prevent the cardboard box from being deformed by the load of the tail cord in the body penetrating portion and the shearing force received when the cord is pulled out.

The temporary fixing means may be one that adheres the terminal including the connector of the tail cord to the lid piece with a double-sided adhesive tape,
Further, it may be a protector having a structure capable of accommodating the terminal connector in a shape that fits into the excess space inside the cardboard box accommodating the cord winding unit.

Therefore, as a preferable mode of the temporary fixing means, an inner lid which covers the opening by being provided between the edges of the two narrow side walls of the corrugated cardboard box, and the winding end end of the tail cord is attached to the inner lid. It is preferable to include a holder that holds both of them in a closed state.

The lid piece is preferably bent in a substantially L shape, and has a structure having a slit cut from the edge at an intermediate fold at a portion near the winding end portion of the tail cord. By doing so, the lid piece is raised from the edge by the length of the slit to form an appropriate opening, and the tail cord can be pulled out without disassembling the cardboard box.

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

That is, a single corrugated cardboard and a continuous narrow side wall are formed by bending two strips in a vertical direction and in parallel at a position where the width of the corrugated cardboard where the corrugated fault appears is vertically divided into two. Up to three wide side walls, and further extending side edges of the two wide side walls are respectively folded to overlap with each other and stitched to form another narrow side wall opposite to the one narrow side wall. Then, a lid piece is extended from both upper and lower edges of the wide side wall, and the shaft body is penetrated through each of the centers of the two wide side walls integrally extended from the narrow side wall formed by intermediate bending. A horizontal hole is formed.

By doing so, the number of corrugated cardboards can be reduced, and since the wide side walls facing each other are integrally connected by one narrow side wall, there is no fear of misalignment or the like. Centering can be done reliably.

The shaft body is preferably a paper tube having high strength and light weight. However, other than this, it is also possible to use a wooden pole or a plastic molded body such as a short pipe.

Since the paper tube and the wooden pole are poor in elasticity, they may fall out only by penetrating the side hole of the cardboard box. Therefore, when a paper tube or the like is used, it is desirable to add an appropriate retaining means.

In the case of a plastic molded body, since appropriate elasticity can be obtained, the molded body can be fixed to a corrugated cardboard box by performing insertion with elastic deformation. However, it is also possible to add a bolt / nut structure to itself and assemble it by screwing without utilizing elasticity, or to separately tighten and fix with a bolt / nut.

〔Example〕

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

As is apparent from this embodiment, the core 1, the cardboard box 2 and the shaft 3 are used for packing the tail cord 4.

The core 1 is formed by stacking a plurality of corrugated cardboard pieces into a donut shape by laminating and integrating them.
In particular, as shown in FIGS. 3 (a) and 3 (b), a groove formed by a notch is formed on the periphery to accommodate the terminal connector of the tail cord.
11 are formed. As shown in FIG. 1, the tail cord 4 is spirally wound around the winding core 1 formed as described above, and is thus preliminarily packed as a cord winding unit 5. The terminal connector 41 at the winding start end of the tail cord 4 is housed in the groove 11 of the winding core 1 in a drop-type manner so that the winding pressure is not applied when it is wound in a spiral.

The corrugated cardboard box 2 is a combination of corrugated corrugated cardboards 21 and 22 having two double-layered structures, as clearly shown in FIG. The left and right side edges are respectively bent to bend edge portions 21a and 22a facing each other,
Two narrow side walls 24, 24 are formed by superimposing 21b and 22b and stitching with a metal tack 23, and a wide side wall is formed between the narrow side walls.
25, 25 are formed so as to be opposed to each other. Then, the upper edge of one of the corrugated cardboards 22 is bent upward in a substantially L shape to cover the lid piece.
Forming 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 and lower lid pieces, for example, when the upper lid piece 22c is the cord insertion / removal side as in the present embodiment, the other side, that is, the lower lid piece, closes the lower opening. It shall be capped and the seams shall be adhesively fixed with adhesive tape or the like.

By the way, the upper lid piece selected as the cord outlet
At 22c, a slit 22d is formed at an intermediate bent portion of the L shape over an appropriate length from the end edge,
It is used to form a cord outlet described later.

The above-described cord winding unit 5 is inserted into the cardboard box 2 through the opening on the upper side and accommodated therein. Therefore, it is needless to say that the narrow width of the cardboard box 2 corresponds to the wide dimension of the tail cord, and the wide width is made to correspond to the winding diameter of the cord winding unit 5.

The shaft body 3 is made to have a length comparable to the narrow width of the corrugated board box 2 by using a paper tube, and by laterally penetrating it into a lateral hole 25a formed in the center of the wide side walls 25, 25 of the corrugated board box 2,
It is arranged in a state of being bridged between the wide side walls 25, 25.
The shaft body 3 arranged in this way has the central hole 12 of the core 1.
And the core 1 is pivotally supported in the cardboard box 2. Therefore, the shaft body 3 receives the weight of the winding core 1 and the tail cord 4 wound around the winding core 1, and causes the wide side walls 25, 25 of the corrugated board box 2 to share the load. The wide side walls 25, 25 are
As described above, since the corrugated corrugated board having the two-layer structure appears on the cord pull-out side, the weight of the tail cord 4 or the like and the shearing force applied when pulling out the cord endure and the lateral hole 25a is deformed. It can prevent such troubles.

Since the paper tube 3 has poor elasticity, there is a possibility that the paper tube 3 may come out of the cardboard box 2. Therefore, a sealing type fixing means for covering the end face of the paper tube 3 and fixing it to the wide side walls 25, 25 of the cardboard box 2 may be included.

In the corrugated cardboard box 2 accommodating and pivotally supporting the cord winding unit 5 as described above, the upper lid piece 22c is placed as shown in FIG. 2 to complete the packaging. The lid piece 22c provided as a lid may be adhesively fixed with an adhesive tape or the like so as not to be easily opened.

Since the tail cord 4 has a connector 42 at the end of winding, if it is allowed to move freely inside the cardboard box 2, it will be connected to the connector 42 by the shock or vibration received during transportation. The exposed end of the core may cause breakage, breakage, or connection failure. Therefore, as shown in FIG. 5, the lid piece 22c
It is desirable to provide a means 6 for temporarily fixing the winding end end of the tail cord on the inside.

The temporary fixing means 6 are two narrow side walls of the cardboard box 2.
Inner lid 6 that covers the opening by being installed between the edges of 24, 24
It is composed of 1 and a holder 62 for sandwiching the inner end of the tail cord 4 with the end portion of the winding of the tail cord 4, both of which are preferably made of cardboard.

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

At the time of laying, as shown in FIG. 6, the lid piece 22c is raised outward from one end thereof by the amount of the slit 22d to form the cord lead-out port 7, whereby the tail cord 4 is made to have the shaft body 3 as the axis. With the rotation of the wound core 1, the winding core 1 is pulled out from the winding end side, and is then dropped from the elevator room,
Can be used for laying.

When the paper tube 2 is used as the shaft body 3, there is a possibility that it will come out of the cardboard box as described above, so it is desirable to add an appropriate retaining means. FIG. 7 and FIG. 8 show a shaft body retaining means and its built-in structure, which meet the demand. Stopper 7 for retaining
Made of hard plastic, tubular insert 71
And a flange portion 72 integrally provided on the rear end side. The insertion portion 71 has an outer diameter slightly larger than the inner diameter of the paper tube as the shaft body 3 and is in a tight fit relationship with the paper tube, and the tip end is slightly reduced in diameter to facilitate press fitting into the paper tube. I can do it. According to such a stopper 7, the insertion portion 71 is press-fitted into the paper tube serving as the shaft body 3 from its end and is pushed until the flange portion 72 is applied to the outer surface of the wide side wall of the cardboard box. Side wall 2
It is firmly bridged between 5,25 and fulfills the prescribed prevention.

It should be noted that a linear convex line extending in the insertion direction is formed on the surface of the insertion portion 71, so that the engagement with the inner surface of the paper tube is good.

FIG. 9 shows another embodiment of the cardboard box 2. In the corrugated board box 2 of this embodiment, one corrugated board 26 is provided with two parallel creases at a position that divides the left and right widths in a state where the cuts where the corrugated faults appear are up and down, and each fold has a right angle. By folding, a narrow side wall 24 is formed between the two folds, and two wide side walls 25, 25 are extended from both side edges of the narrow side wall through the folds. The extended end side edges of the two wide side walls 25, 25 are folded at appropriate positions so that a width corresponding to the narrow side wall 25 can be obtained, and two bent end portions 26a formed by the folds are formed. The second narrow side wall 24 is formed by superimposing the two, 26a on each other and stitching with the metal tack 23.

In the cardboard box 2 having the rectangular frame shape as described above, the lid piece 26b similar to that of the above-described embodiment is extended from one upper edge of the wide side walls 25, 25. Although not particularly shown, the lid piece is formed on the lower edge of one of the wide side walls 25, 25 as in the above-described embodiment.

At the center of the wide side walls 25, 25, a lateral hole 25a is formed in one side wall as shown in the figure, and is used for arranging the shaft body therethrough. In that case, since the corrugated faults on the wide side walls 25, 25 are arranged to appear in the upper and lower directions,
The load applied to the shaft can be applied with the same strength as in the figure.

According to the cardboard box of this embodiment, however, the stitching portion is only required to be formed on one narrow side wall portion, and the other narrow side wall is integrated with the wide side wall. Since the horizontal hole 25a is formed in one corrugated cardboard, the horizontal holes can be easily centered on 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 is composed of one flanged pipe 31 and another flanged pipe 32 inserted therein, and both are made of hard plastic.

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

Then, at the tip, as shown in FIG.
Each of the 33a is expanded outwardly in the shape of a scoop, or as shown in (b), a straight split element 33b,
Small protrusions 33c are formed on the outer circumference of each of the 33b.

Insert it while it is narrowed.

Then, by inserting the flange until it hits the side wall 25, the chevron-shaped part at the tip or the small protrusion 33c is projected to the outside of the other side wall, and the dividing element narrowed accordingly.
33a, 33a or 33b, 33b is expanded by its elastic return force,
As a result, the tip end is brought into a state of being locked to the flange portion of the flanged pipe 31 on the other side wall, and the shaft body 3 is assembled in a predetermined retaining manner.

Such a shaft body pulls out the flanged tube 32 inserted therein, and then pulls out the flanged tube 31 of the outer sheath, so that the cord winding unit 5 (see FIG. 1) housed in the cardboard box is removed from the cardboard box. Allows to take out. This is used when the tail cords once packed are replaced with the terminal connectors 41, 42 due to a specification change or the like. The reference numeral 33d is a needle-like protrusion provided on a flange portion which is provided on the wide side wall 25, and by fixing it to the wide side wall 25 by pressing, the shaft 3 can be fixed and prevented from rotating.

FIG. 12 and FIG. 13 show another two different embodiments of the shaft body which can be inserted and removed and its mounting structure.

In the embodiment shown in FIG. 12, the flanged tubular body 34 is laterally penetrated from one wide side wall 25 (left side) and bridged to both wide side walls 25, 25, and the circular plate is inserted from the other wide side wall 25 (right side). Apply the seat 35 in the shape of, and penetrate the bolts 36 into these flanged pipes 34 and seat 35,
By tightening with the nut 37, a predetermined mounting and fixing is achieved. By disassembling the bolt 36 and the nut 37, the shaft body can be removed.

In the embodiment shown in FIG. 13, the flanged female screw tube 38 is attached to one of the wide side walls 25.
Insert from the left side and strengthen to both wide side walls 25, 25 pipe,
The male screw tube 39 with a flange is inserted from the other wide side wall (right side) and screwed into the female screw tube 38 to be assembled as a predetermined shaft body 3 in a cardboard box. By removing the screw connection of both pipes, it is possible to extract the shaft.
