Description

[Detailed description of the invention] The present invention relates to a folded press plate for end-face packaging of metal coils.

Regarding 4i-sided packaging of metal coils, for example, Japanese Patent Application Laid-Open No. 57
- In Publication No. 68315, the end of the coil side packaging cylinder protrudes from the end of the coil to be packaged, the length t of the protrusion is made longer than the thickness t between the inner and outer sides of the coil, and the protrusion is formed on the end face of the coil. Fold it with a push plate in contact with it, make radial folds appear at approximately equal intervals on the bends of the adjacent push plate, rotate the push plate to make the protrusions in the same direction on the folding surface, and then fold...
A packaging method and packaging apparatus 19 have been proposed in which the inner peripheral edge of the coil is folded along the inner surface of the coil.

However, in order to generate heat and fold the node-shaped parts of the coil outer wrapping paper that protrude from the coil end surface along the coil end, the outer side of the coil end-wrapping iron paper snail-shaped part is formed by a pressing plate, and the inner part is folded. After being restrained by a rod, the pressing plate is slid continuously from the outer circumference of the coil to the end by turning 90 degrees in the middle, and folds are generated irregularly between the pressing plates. , with the push plate applied over the entire length of the coil end face (1/2 of the difference between the outer diameter and the circle diameter), fold the folds that have occurred perpendicularly to the coil end face in the same direction along the coil end face. However, as the range of the outer diameter of the coil becomes wider, the range of the wall thickness of the end face of the coil also becomes wider. 1.When folding the push plate, if the length of the push plate (radial direction at the end) is the same, if the outer diameter of the coil is small, the push plate may interfere with the width direction at the initial stage of folding, or the coil outer diameter may If the coil is too thick, it will not be possible to hold down the entire length of the coil wall in the end face folding method, resulting in poor or untidy finish of the coil end packaging. However, it was not desirable in terms of production efficiency to use a coil with a size corresponding to the coil diameter, so it was desired at that time.

The present invention takes advantage of the above-mentioned problem, and even if the outer diameter of the coil is large or wide, a push plate is applied to the outer circumference of the coil to wrap the end. are arranged alternately with the push plates, and from the outer periphery of the coil to the center e (
V-t] Continuously slide the coil until it reaches the center so that folds are formed along with the carrier, then lie down in the same direction along the end surface, and place the inner peripheral edge of the folded surface into the center hole of the coil. So, in order to perform end-to-end wrapping of the coil, at the beginning of folding the coil end-wrapping paper according to the outer diameter of the coil, the upper part of the push plate should be folded. To provide a center-folding push plate having a structure that prevents mutual interference between the push plates by bending /J90°.

Cylindrical portion 8 protruding from the coil end face of the coil outer wrapping paper
The shape of the pressing plate is triangular in shape, but the length of the coil is the length of the lower side of the pressing plate multiplied by the number of pressing plates. If the diameter is longer than the total length of the outer diameter, the upper parts of the folded press plates will interfere with each other.

In order to solve this problem, the present invention first bends the two-part triangular plate 13 and the dowel-part crescent plate 4 at right angles (C process). In the state of step C, the lower triangular plate 4 contacts the end face of the coil and closes as shown.

+i.

The elasticity of the spring 20 prevents the packaging material from being bent backwards. The lower triangular plate is a coil! For the 7iiiil, it is in the horizontal position, and its upper end is at the position i of the outer circumference of the coil yiIiii1111]. The air cylinder 12 for the stopper is activated and the upper triangular plate and lower triangular plate are assembled into a single body in step C (barrel).

In other words, when the coil diameter is relatively small, the lower triangular plate of the push plate is bent from the lower triangular plate to the outer circumference of the coil, and the lower triangular plate is in contact with the outer circumferential surface of the coil, and either the lower triangular plate or the end face of the coil is in contact with the outer circumferential surface of the coil. After rotating at right angles to a horizontal position, and further sliding the upper part of the lower triangular plate to the 1) J position on the outer periphery of the coil end face, the upper triangular plate quickly returns to its original position, and the upper and lower triangular plates become one body. Since it is folded while touching the coil end (2), the two parts of the push plate do not interfere with each other.

Also, when the rotating cylinder 107 is rotated, the push plate 1.1-0 slides on the end face of the coil and folds the folds formed on the push plate 1-i41, or the above-mentioned σ) upper triangle/lost connection. Fixed bottle 1]
By fitting 1- into the stopper guides 14 and 15, the upper and lower parts of the push plate are integrated and slide smoothly on the coil end face, so that the generated folds are laid down in an orderly manner, and the coil end face is smooth. The packaging is Ci] function.

In accordance with the present invention (as detailed above, in the case of non-inventiveness, in forming folds of a coil with a diameter of a dog, a press plate that integrates an upper triangular plate and a lower triangular plate is formed). The entire wall thickness is pressed and slid, and when forming folds on a coil with a small diameter, the upper triangular plate is bent at the joint with the lower triangular plate, and the lower triangular plate is essentially used as a pressing plate to press against the coil thickness. It has the ability to slide, and the wrapping form of the end face of the coil can be done reliably and easily, and its mechanical effect is excellent.
