JPH08319075A - Transport box for elevator's flat movable cable - Google Patents

Abstract

PURPOSE: To make a working spot small, and prevent a cable from kinking by vertically setting a thin type transport box housing a paper bobbin on which a flat cable is wound, supporting the bobbin by a bearing while inserting a shaft made out of a paper tube, which is located above the center of the box, and letting the flat cable slackening device be thereby constituted. CONSTITUTION: A flat type movable cable is wound on a bobbin 11, and is housed in so as to be wrapped into a thin type hard board box (transport box) 14. The transport box 14 is vertically set at a laying site, the lid 15 of the transport box 14 is then opened, and the lid 15 is folded and bent so as to be fixed, so that an opening of the box is thereby formed. The bobbin 11 is aligned with the shaft hole of the box for letting a paper made shaft 12 be inserted so as to be fixed. In this case, a square cut-out section 18 makes it easy to penetrate the paper made shaft while being aligned together with the box 14 and the bobbin 11. Besides, when the movable cable is slackened, since a shaft position is located upward, and the bobbin 11 is also positioned above the box, there is thereby a gap between the lower section of the bundled cables and the bottom section of the box, so that the cables are easy to be slackened without being in contact with the bottom of the box.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport box for a flat moving cable of an elevator.

[0002]

2. Description of the Related Art An elevator car traveling in a hoistway is provided with a moving cable.

[0003] The moving cable is a cable of a portion of an electric wire connecting a control panel in a machine room of an elevator and an operation panel in a car that moves as the car travels, and is also called a tail cord. I have.

A moving cable is a group of electric wires used in circuits for controlling a door power supply, controlling a door opening / closing device, and interphone communication, in addition to various operation signals necessary for operating an elevator. Terminals are provided at both ends.

The moving cable used for the elevator is determined by the regulations (according to Article 25 of the technical standard of electrical equipment and Article 35 of the notification of Ministry of International Trade and Industry Notification No. 271 of 1965 which defines the details), JIS It must comply with C3408 "elevator cable". In this standard, only round cables were initially used, but flat cables were later added (1973).

[0006] The flat cable has a structure in which a plurality of wire core groups are arranged in parallel, has excellent suspension characteristics, and is excellent in seismic resistance, such as little shaking during running of the car. Therefore, in recent years,
Instead of the conventional round cable, a flat type moving cable has been generally used.

At the time of elevator installation work, an elevator hoistway is formed in a building, a guide rail is fixed inside the elevator, and after the car is assembled, the moving cable is laid between the machine room and the car. You.

In the conventional laying work, in the case of a long and thick moving cable 1, the moving cable 1 is wound around a large wooden bobbin 2 and placed on the floor of the machine room (FIG. 6), and the moving cable 1 is rotated while rotating the bobbin 2. Unwind and hang it in the hoistway and connect it to the car. Or, if it is a little smaller, place the bundle-wound moving cable 3 on the turntable 4 (Fig. 7).
In the case of winding and loosening, or in the case of a small bundle winding 3, the worker 5 may hold it and loosen it (FIG. 8).

[0009]

The flat moving cable for an elevator used in this manner varies depending on the traveling distance of the elevator. However, in the case of a general residential elevator, the length is 20 m to 80 m, and the weight is about 20 m to 80 m. The requirement within a range of about 1 kg / m (that is, a cable weight of about 80 kg or less) can meet the demand. Such a cable is wound around a bobbin and hung from the machine room, or pulled up from the lowest floor to perform the laying work.

At this time, as described above, in the case of the long moving cable 1 (80 m or more), the wooden bobbin 2 having a diameter of about 1.8 m (FIG. 6) is used for laying. Compared with a round cable, a flat moving cable does not return to its original state when twisted, so that a plurality of flat cables cannot be wound parallel to a winding shaft like a round cable. For this reason, in the case of a flat cable, a single cable has dozens of turns (lap winding), so that the outer shape is larger than that of a round type that can be wound parallel to the winding axis. In the case of a short moving cable (20 to 80 m) 3, the cable is wrapped alone (bundled) and placed on the turntable 4 (FIG. 7), or the worker 5 holds and unwinds (FIG. 8) ).

[0011] Such unwinding work occupies a large work area, causes kinks in the cable, and breaks up when the bundle is wound. And the efficiency of the work is reduced, which is a problem.

[0012]

In order to solve such a problem, according to the present invention, a flat moving cable housed and transported in a cardboard shipping box is unwrapped almost as it is. To make it possible.

That is, a flat moving cable is wound around a paper bobbin, stored and packed in a cardboard box for transportation, transported, and the transport box is placed on the floor of a machine room at the site where the moving cable is laid. Open the package, attach the rotating shaft made of paper tube to the bobbin around which the cable is wound, and rotate this bobbin to unwind the flat moving cable, hang it down in the hoistway, and connect it to the car to lay the cable. Is intended to simplify the process.

[0014]

As described above, since the moving cable is unwound from the transport box as it is, the required work area is small,
In addition, the flat cable hangs down in the hoistway without twisting (kinking), and the laying work can be performed smoothly and in a short time.

Moreover, since the transport box and the bobbin are both made of paper, they are lightweight and inexpensive, yet have sufficient strength and durability.
It can be easily unwound.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in FIGS.

A bobbin for winding a moving cable and a transport box for storing and packing the moving cable are constructed as follows.

1. Configuration of corrugated paper bobbin.

Corrugated paper (for example, double-sided corrugated board,
Four paper tubes are arranged (adhered) on a circular line around a central shaft hole 7 of a circular flange 6 made of a thickness of about 6 mm) to form a bobbin cable winding shaft 8. Similarly, this collar 6 and the paired collar 9
Then, four paper tubes 10 of a size to be fitted to the paper tube 8 are arranged (adhered), and the two flanges 6 and 9 are fitted together to form the bobbin 11. Flat moving cable 1 is attached to this bobbin 11.
Or wrap around 3. At this time, the terminal of the cable terminal is 4
The book is placed in the inner space formed by the winding shaft 8 formed by the paper tube 8.

2. Paper tube support shaft A paper tube of a size that fits the shaft hole 7 of the collar of the bobbin 11,
A bobbin support shaft 12 is formed, one end of which is thickened, and a stopper 13 is provided.

3. Construct a thin transport box made of corrugated board.

A box (thin box) having a substantially square shape for accommodating the bobbin 11 around which the flat movable cable 1 or 3 is wound and having a thin thickness is used as the transport box 14 made of corrugated paper. The thickness of the transport box 14 is set to a size that matches the thickness (height) of the bobbin 11. The lid 15 is formed by projecting both sides of the box and folded from both sides to form a closed shape. When the cable is later unwound for laying work, the two lids are bent outward and stuck, and Used to reinforce the opening of the
In the case of a moving cable of about 60 m, the size of the box is approximately 1 m square.)

The support shaft bearing hole 16 of the bobbin 11 is formed so as to be deviated from the center position of the transport box (the square surface side) 14 toward the upper side of the box (the side on which the box cover 15 is provided).

From above the center line 17 of the bearing hole 16 (in the direction of the lid), a notch is provided on three sides excluding the center line to form a square enclosing the upper half of the bearing hole. This is used as a bearing hole reinforcing plate 18. When the cable is unwound, the reinforcing plate (notch portion) 18 is bent downward and adhered to reinforce the bearing portion, and withstands the load at the time of supporting and rotating the cable.

Further, when the reinforcing plate 18 is bent,
Since a space is created above the bearing hole on the side of the box, the support shaft 1
When the bobbin 11 is incorporated into the bobbin 11, the support shaft 12 is moved slightly inside the box and above the bobbin 11.
It is easy to fit the support shaft 12 into the bearing hole 16 on the box side by shifting the bobbin 11 after that.
This is also easy.

This is because when there is no such a space portion, the positions of the shaft hole 7 of the bobbin and the bearing hole 16 of the box must be precisely aligned, which is very troublesome.
A great advantage.

The bearing hole 16 may be formed as an elliptical hole. In this case, there is an advantage that the support shaft is less likely to come off during rotation.

4. Packing and unwinding of the moving cable.

The flat moving cable 1 is wound around a bobbin 11, stored and packed in a thin cardboard box (transport box) 14, and transported to an elevator installation site.

The transport box 14 is installed vertically on the floor of the machine room at the site where the moving cable is laid, the lid 15 of the transport box 14 is opened, and the lid 15 is bent and fixed to form an opening of the box.

On the other hand, the bobbin is aligned with the shaft hole 16 of the box and fixed through the paper tube shaft 12. At this time, a square notch 18 larger than the shaft hole 16 facilitates the passage of the paper tube shaft 12 in accordance with the box 14 and the bobbin 11. Also, when unraveling the moving cable, the bearing is located above and the bobbin is located above the box, and there is a gap between the bottom of the bundled cables and the bottom of the box, so that the cable does not touch the bottom of the box. , Easy to loosen.

In this way, the moving cable is unwound and hung down in the hoistway to be connected to the car. The present invention, by the above-mentioned configuration, obtains its function and effect, and a combination of a bobbin suitable for winding a flat moving cable and a transport box suitable for storing the bobbin makes use of respective advantages,
Despite being a lightweight and inexpensive combination of a paper bobbin as well as a paper bobbin, a cable unwinding device with sufficient durability and strength is realized.

[0033]

According to the present invention, the transport box of the flat moving cable of the elevator can be constituted by an inexpensive corrugated cardboard box, and furthermore, it is diverted as the moving cable laying work device as it is, and the moving cable is unwound. The advantages are that the work is easy, there is no kink of the moving cable, the laying work is quick, and the efficiency is improved.
