Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to reelless coil packaging with a drawer, particularly a PC
The present invention relates to a reelless coil made of a wire having a relatively high strength such as a steel stranded wire and having a good linear restoring property against bending, that is, a package with a drawer for a coil not wound around a drum or the like.

(Prior Art) Conventionally, as shown in FIG. 4, a reelless coil package with a drawer is known. The illustrated reelless coil packaging has a peripheral paper tube 2 made of cardboard wound circumferentially around the outer circumference of a steel stranded wire reelless coil 1, and two longitudinal bands 3 are mutually wrapped around the peripheral paper tube 2. It is wound in the circumferential direction at spaced positions and tightened and fixed by a clasp, and one end of a plurality of lateral bands 4 is connected to a circumferentially spaced part of an annular ring 6 which constitutes a drawer 5, thereby forming an annular ring. 6
Is located at the center of the pull-out end face of the reelless coil 1, the horizontal band 4 is extended on the outer peripheral paper tube 2 in parallel with the axis of the reelless coil, and the other end of the horizontal band 4 is formed into a circle similar to the annular ring 6. It is connected to an annular ring (not shown), and this annular ring is positioned at the center of the end surface on the opposite side of the reelless coil 1, whereby a reel is formed by a plurality of horizontal bands extending in the length direction of the outer peripheral paper tube. An annular ring is held at the center of the end surface of the coil. The packing of the reelless coil is generally completed by wrapping both end surfaces and the inner peripheral surface of the reelless coil with wrapping paper.

The packing of the reelless coil described above uses the drawing tool 5 constituted by the annular ring 6 supported by the lateral band at the center of the end face thereof, and the steel stranded wire 8 from the winding start end inside the reelless coil. By pulling out through the pull-out hole 7 of the annular ring 6, it is possible to smoothly pull out to the outermost end of the reelless coil in contact with the outer peripheral paper tube 2.

(Problems to be solved by the invention) However, in the annular ring, (1) the position of the connecting end of the horizontal band is easily shifted to the left and right on the ring, and therefore,
When attaching a horizontal band to a reelless coil, it is not easy to fix the mounting position of the horizontal band. (2) When pulling out the wire rod of the reelless coil, the wire rod directly contacts the horizontal band connecting end on the annular ring. The lateral band connecting end is worn or damaged and separated from the annular ring,
(3) Wires such as PC steel stranded wires that have a large linear recovery property against bending are continuously drawn out by their own large restoring force. Therefore, the drawing work is interrupted to cut the PC steel stranded wire to the desired length. However, there is a problem that the reelless coil may be disturbed when it is stopped.

The present invention seeks to provide a reelless coil package with a drawer without the above-mentioned problems.

(Means for Solving the Problems) According to the present invention, a reel with a drawer in which the drawer is held at the center of the end surface of the reelless coil on the drawer side by a plurality of lateral bands extending in the length direction of the outer peripheral paper tube. In the coilless packaging, two regular polygonal rings of the same shape are formed by arranging the regular polygonal corners of one regular polygon on the bisector of one side of the regular polygon and superposing them on each other. It is characterized in that the lateral band ends are connected to the corners of the regular polygonal ring.

In implementing the present invention, the regular polygonal ring is preferably a regular triangular ring or a regular square ring.

(Operation) According to the present invention, the positions of the connecting points of the horizontal bands are fixed by connecting the horizontal bands to the corners of two regular polygonal rings having the same shape.

Further, by defining the polygonal wire rod drawing holes only by the sides excluding the corners to which the horizontal bands are connected, each corner of the polygonal hole is drawn when the wire rod is drawn while moving along the inner circumference of the drawing hole. At, the wire rod is braked. Therefore, the drawing of the wire rod can be stopped at the required drawing length, and the winding disorder can be prevented when the wire rod is cut. Further, the wire does not come into contact with the connecting end of the lateral band, so that it is possible to prevent the connecting end from being damaged due to the contact of the wire and the ring from being held incorrectly.

(Embodiment) FIGS. 1 to 3 show an embodiment of the present invention. In the illustrated example, a square ring 10 having a side of 250 to 400 mm is formed from a PC steel rod having a diameter of 7.4 to 11 mm. As shown, two identical square rings 10 and 10 are connected together by superimposing them so that the corner C of the other square is positioned on the bisector B of one side A of the one square. Therefore, in this example, since the rings 10, 10 are square, they are overlapped with each other by being shifted by 45 ° around the center O, and welded at the point D where the sides A, A of both square rings 10, 10 intersect.

Square ring of drawer formed as described above
As shown in FIG. 3, a horizontal band 4 is formed at each corner C of the corners 10 and 10.
Fold back the ends of and engage with them, and secure with clasps 11.

(Effect of the Invention) According to the present invention, the position of the connection point between the drawer ring and the band is fixed, the packing can be performed easily, and the drawing of the wire is stopped at the required drawing length to cut the wire. It is possible to prevent winding disorder during the operation. Further, it is possible to prevent the wire rod from damaging the connecting end of the lateral band.
