That is, the lower end 10a of the second support shaft 10 is provided with a recess 12 having a rectangular cross section that corresponds to the protrusion 11 having a rectangular cross section formed on the upper end 9b of the first support shaft 9. The first and second support shafts are connected by engagement of the protrusion 11 and the recess 12 to form a support shaft extending substantially perpendicular to the bottom plate 5.

A protrusion 13 similar to the protrusion 11 having a rectangular cross section formed on the upper end of the first support shaft 9 is provided at the upper end 10 b of the second support shaft 10 .

The protrusion 13 is shaped so as to engage with a rectangular hole 8 in the upper plate 7 provided on the winding receiving reel member push rod 6 to fix the upper end of the spindle.

On the other hand, 14 is a first winding receiving reel member, and 15 is a second winding receiving reel member, which are reel bodies having the same structure and which are virtually replaceable.

The structure of the winding receiving reel member will be described in detail.

The winding receiving reel member has a sleeve body 16 having an inner diameter that engages with the diameter of the support shaft, and a flange-like disk body 17 is provided at the lower end of the sleeve body.

On the other hand, the flange-like disk body 17 is provided with a rising frame 18 suitable for supporting the inner diameter of the winding, and furthermore, a winding support rod 1 extending radially from the edge of the flange-like disk body 17 is provided.

The tip of each of the winding support rods is bent upward as shown in FIG.

The winding receiving reel members 14 and 15 are rotatably mounted at fixed positions in the longitudinal direction on the support shafts 9 and 10, respectively.

As means for this, in this embodiment, for example, the support shaft 10 is provided with a groove 21, and the sleeve body 16 of the winding receiving reel member is provided with a bolt-shaped pin 22.
A mechanism is adopted in which the tip of 2 is engaged in the groove 21.

Further, as means for passively controlling excessive rotation of the winding receiving reel member, excessive rotation control means 23 is provided between the spindle and the sleeve body of the winding receiving reel member.

In this embodiment, the following mechanism is applied as the excessive rotation control means 23.

That is, first, a groove 24 having a polygonal cross section is provided at an arbitrary position on the support shaft, and on the other hand, a position opposite to the circumferential surface of the sleeve body 16 of the winding receiving reel member is formed in correspondence with the groove 24. A pair of elongated holes 25 are provided.

Next, the winding receiving reel member push rod 6 is horizontally suspended, and the second
While supporting the upper end portion 10b of the support shaft, it prevents the second winding loaded onto the second winding receiving reel member from coming off upward.

The two types of windings loaded in this way are each supported by independently rotatable winding receiving reel members, and the tips of the windings are taken out from between the side frames corresponding to each winding receiving reel member. Unrolled independently.

As described above, the device of this invention has a structure in which at least two different types of windings can be loaded onto independently rotating winding receiving reel members provided on one unwinding drum device. This allows different types of wiring work to be performed at the same time.

For example, when performing indoor electrical wiring work, if two types of windings are loaded, one for the main line and one for the branch line, it is possible to perform the main line and branch line wiring work simultaneously or selectively. It can be said that this is an extremely effective winding unwinding drum device for this type of construction.
