In conventional winding drums, winding grooves are cut into the outer circumferential surface of the winding drum in order to wind cables in an orderly manner, but the cutting process is complicated and requires a special processing machine. It was hot. The reason why this is necessary is due to the special arrangement of the grooves cut into the winding drum.

Details of a specific example of such a special groove arrangement will be explained with reference to FIG. FIG. 1 is a developed view of the winding trunk. A is an example where the number of turns of the cable is an integer (in the figure, the first layer is 5 turns and the second layer is 6 turns).
B shows an example in which the number of turns of the cable is a non-integer number (in the figure, the first layer has 6.5 turns and the second layer has 6.5 turns). As is clear from the figure, the first layer of cable 1 is wound up in an orderly manner as it is guided by the cable winding groove 2 cut into the winding trunk, and the second layer is guided by the first layer of cable. The third layer is rolled up in the same way.
The fourth layer... and so on, are wound in an orderly manner and are wound in multiple layers.

The present invention proposes a completely different rope winding drum having a flat outer peripheral surface, instead of the rope winding drum having a rope winding groove on the outer circumference of the winding trunk. Although such flat-wound trunks without cable winding grooves are easy to manufacture, they have the disadvantage that the cable winding becomes disordered.

What should be noted when winding the cable is that, as is clear from Figure 1 A or B, the winding direction is changed little by little at points a, b, c, and d. This is what is happening. The present invention focuses on this change, and has a structure using a uniform winding groove piece in which the cable winding groove is provided only at the changed point. Even if the uniform winding groove pieces are attached at two locations a and b, they can be attached at four locations a, b, c, and d, and six or eight locations including e and f (not shown). Although there may be more than one, in practice, a sufficient winding effect can be obtained at four locations as shown in the figure. And between the cable and flange in the first layer
Usually, cable guide pieces 3a and 3b are provided in the space so as to fill the space.

This proposal eliminates the need to cut such a special winding groove 2 directly into the winding drum, and instead installs a winding groove piece, which will be described later, at an appropriate location on the winding drum, which can achieve the same winding effect. That is, each of the above-mentioned changes is provided.

In the figure, the cable consists of parallel parts b to c and d to a that are wound parallel to the flange inner wall surface and cross parts a to b and c to d that are wound at an appropriate angle to the flange inner wall surface. This is continuously wound up into a spiral shape onto the winding drum. Therefore, when the cable is wound around the winding drum while traveling straight parallel to the inner wall surface of the flange, the winding direction is changed twice during the winding, so that each pitch is adjacent to the other. It is wound up while being forcibly moved laterally to the next door. In order to successfully change the winding direction twice as described above, it is necessary to have a cross section that is at least 25% to 30% of the total circumference of the winding drum, and each change point a, b ,c,
It is necessary to add a forced lateral movement force at d. For this reason, in the past, complicated cable grooves 2 had to be cut and installed with great difficulty, but this proposal eliminates the need to cut such cable grooves 2, provides an appropriate cross section length, and By arranging the later-described regular winding groove pieces at each of the above-mentioned change points, a forced lateral movement force is applied to the cable, making it possible to easily and simply wind the cable in a uniform manner.

Here, the details of the evenly wound groove piece will be explained. Figure 3 is an enlarged cross-sectional view of section A-A in Figure 2;
FIG. 4 is an enlarged cross-sectional view taken along line BB in FIG. 2. Both of these enlarged views show cut surfaces of the regular winding groove pieces 4 and 5, and each regular winding groove piece is a horizontally elongated integral piece, and the body side of the surface in contact with the winding trunk has a rope winding. A large number of grooves 2 are cut in the width direction of the winding drum. The difference between the regular winding groove pieces 4 and 5 lies in the number of grooves in the winding groove 2, with the former having one more groove than the latter. This difference is also due to the presence or absence of the cable guide piece 3 (the cable guide piece may be omitted).

This uniformly wound groove piece is manufactured as follows.
That is, the width W of the winding groove piece (usually 1.0 to 1.0 of the cable diameter)
Using a plate with a width that is an integral multiple of 2.0 times), cut a specified number of winding grooves in the width direction of this plate at a specified radius and at a specified pitch interval, and then make this processed plate width W. By cutting it into several pieces, the uniformly wound groove pieces 4 having the meandered groove arrangement as shown in FIG. 3 are manufactured. A part of the end face of the uniformly wound groove piece 4 is cut and removed to produce a uniformly wound groove piece 5 having a meandering groove arrangement as shown in FIG.

These regular winding groove pieces 4 and 5 may be fixed by welding directly to the winding trunk, but in general, screw holes are machined into the winding trunk to accommodate changes such as different cable diameters. It is attached with a structure that allows it to be attached, detached, and replaced by using a bolt that is screwed into this.
In particular, when the load must be taken into account, locking members welded to the winding drum are provided at both ends of the regular winding groove pieces 4 and 5, and the structure is such that they can be attached and detached while being sandwiched between the locking members. Alternatively, a concave groove may be provided in the winding trunk, and the lower part of the regular winding groove piece may be sunk into the concave groove to smooth the winding of the rope without any steps.

If the winding drum is equipped with the above-mentioned winding grooves, the direction of movement of the cable when winding will be forcibly changed due to the groove effect of the winding grooves, resulting in uneven winding. In addition, such a regular winding groove piece has an excellent feature that it can be easily attached to a winding trunk without a conventional winding groove. In addition, changes in cable diameter can be easily accommodated by simply replacing the winding groove piece.
Since the uniformly wound groove piece itself has a simple structure, it is very effective in carrying it around, replacing it, installing it, and manufacturing it without any difficulty.

The above description has been made of the regular winding of the winding drum portion, but it is also necessary to perform regular winding of the flange portion as well. This becomes more important as the number of layers increases.

FIG. 5 shows a cross section along the line CC in FIG. 2. In the figure, the ridgeline 6a of the protrusion 6 provided on the inner wall surface of the flange is formed to slope inward as it goes outward. By doing this, it is possible to prevent disturbances in the multi-layer winding portion of the cable 1. The reason for this can be explained with reference to FIG. 6. The tension due to the winding load of the cable 1c is applied equally to the lower cables 1a and 1b in the parallel part, but in the cross part, a torsional force T is further applied. The cable 1c is deformed as shown by the broken line,
A larger load acts on the rope 1b than on the rope 1a. As a result, the cable 1c is deformed more toward the cable 1b, and as a result, the cable 1c is eccentrically moved toward the cable 1b.

Moreover, depending on whether the cable is S-twisted or Z-twisted, the outer diameter of the cable will expand at this time.
Or, it is decided whether to reduce the size. However, with this understanding in mind, the inward angles α and β of the ridgeline 6a of the protrusion should be appropriately determined.
