Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a folded press plate for end face packaging in shipping and packaging of coils such as thin steel plates.

(Prior art) Regarding end-face packaging of metal coils, for example, in Japanese Patent Application Laid-open No. 57-68315, the end of a coil side wrapping cylinder is projected from the end face of the coil to be wrapped, and the length l of the protruding part is set to the inside and outside of the coil. The thickness between the sides is larger than t, the protrusion is folded in contact with the end face of the coil by a push plate, radial folds are protruded at approximately equal intervals between adjacent push plates, and the push plate is slid to protrude. A packaging method and a packaging device have been proposed in which the pleats are laid down in the same direction on a folding surface, and then the inner peripheral edge of the folding surface is folded along the inner surface of the coil.

However, in order to neatly fold the cylindrical part of the coil outer wrapping paper that protrudes from the coil end face along the coil end face, the outside of the cylindrical part of the coil end wrapping paper is restrained by a pressing plate, and the inside part is restrained by a pleating rod. At the same time, the push plate is continuously slid from the outer circumferential surface of the coil to the end face by turning 90 degrees in the middle to generate folds regularly between the push plates. With the push plate applied over the entire length (1/2 of the difference between the diameter and inner diameter), it is necessary to collapse the folds that have occurred perpendicularly to the end face of the coil in the same direction along the end face of the coil.

However, as the range of the outer diameter of the coil becomes wider, the range of the coil end face thickness also becomes wider, and when folding the end face in the same direction after creating folds, the length of the push plate (radial direction at the end face) becomes If they are the same, if the outer diameter of the coil is small, as shown in FIG. 7-1, an interference part a will occur in the width direction of the pusher plate (ie, in the outer circumferential direction of the coil) at the initial stage of folding.

Furthermore, when the coil width is narrow and the coil diameter _D1 is small, as shown in Figure 7-2, with the conventional single push plate, an interference part a is created on the outer circumferential surface of the coil at the start of paper folding, which is inconvenient. It is. On the other hand, the outer diameter of the coil is
If D is ₂ or more, there will be no interference of the push plate in the coil width direction, but if the coil width is narrow, interference will occur in the coil width direction as well.

Furthermore, if the outer diameter of the coil is large, as shown in FIG. 6-2, it becomes impossible to suppress the entire length of the coil wall thickness when the end face folds down. FIG. 6-1 is an explanatory diagram of a conventional example when the coil diameter is small.

However, since it is unfavorable in terms of work efficiency to replace and use push plates with dimensions corresponding to the coil diameter, an improvement has been desired.

(Problems to be Solved by the Invention) In order to eliminate the drawbacks of the prior art, the present invention securely holds the outer periphery and end face of the coil over the entire size range, even when the range of the outer diameter and width of the coil is wide. The purpose is to provide a presser plate that can be used to ensure an orderly packaging finish. The present invention provides a center-folding press plate having a structure that prevents mutual interference between the press plates by bending the plates approximately 90 degrees.

In the press plate 110 of the present invention, the upper triangular plate 13 and the lower triangular plate 4 are arranged at the same level, and the minimum outer diameter coil uses only the lower triangular plate, the upper triangular plate is used with it rotated in the right angle direction, and the middle In the case of a coil with an outer diameter of When the lower triangular plate is almost parallel to the end face of the coil, return the upper triangular plate to its original position, connect the upper and lower triangular plates with a fixing pin, and use the upper and lower triangular plates as one unit.

Further, in the present invention, the upper and lower triangular plates are connected by removable pins in order to connect the upper triangular plate and the lower triangular plate in a straight line and improve the overall rigidity when used as one unit.

That is, when the upper triangular plate 13 and the lower triangular plate 4 are aligned, the fixing pin 11 attached to the lower triangular plate is moved by the operating air cylinder 12 to the base plate superimposed on the upper triangular plate via the stopper guide 14. Stopper 15 fixed on 16
The upper and lower triangular plates are connected to form an integral structure, which improves the overall rigidity and smoothes the folding effect of the wrapping paper.

Next, the operation of the present invention will be described. A wound strip coil 134 is placed on each of a plurality of pedestals 102 arranged in parallel on the floor 101. Then, the bogie 104 is run along the horizontal rails 103, 103 and stopped at the position of the coil 134, and the center line a' of the coil 134 and the horizontal axis a are aligned in the horizontal direction. stop at that position.

Then, the machine frame 106 is moved along the rails 105, 105 on the truck 104, and the opening/closing arm 1 of the push plate 110 shown in FIG.
The coil 134 is moved until the distance from the center of the rotation shaft 109 of the coil 134 reaches a predetermined dimension L, and then stopped.
The center line a' of 34 and the horizontal axis a are aligned in the vertical direction.

When the opening/closing arm 108 in FIG. 1 is closed around the rotating shaft 109, a plurality of push plates 110 arranged along the outer periphery of the selvedge S of the cylindrical packaging sheet and a sliding device (not shown) A pleat is formed by both numbers of pleat forming rods 113 set at positions .

The present invention has the following features in order to maintain a moderately high wrapping paper restraint rate during the coil end face wrapping paper folding and folding process even when the coil outer diameter and width range is wide.
The push plate is configured to be rotatable (folded in the middle) in a right angle direction at approximately the center in the longitudinal direction (radial direction of the end face of the coil), and this operation will be explained with reference to FIG.

When the cylindrical portion S protruding from the coil end face of the coil outer wrapping paper is folded by the coil end face, the shape of the push plate is approximately triangular, but the length of the side at the bottom of the push plate × If the length multiplied by the number of push plates becomes greater than the total length of the outer diameter of the coil,
As shown in Figure 1, the upper parts of the folded press plates interfere with each other in the direction of the outer circumference of the coil.

The present invention solves this problem when the outer diameter and/or width of the coil is relatively small.
First, before the push plate comes into contact with the outer periphery of the coil, the upper triangular plate 13 and the lower triangular plate 4 are kept bent at right angles (step a in the figure) in advance as shown in FIG. Then a
In the state of the process, the lower triangular plate 4 is closed on the end face of the coil so as to be in contact with the outer periphery of the coil. (Step b) Further, when the opening/closing arm 108 is closed around the rotating shaft 109 and the lower triangular plate 4 forms an angle of 45° to 60° with respect to the end face of the coil (Step c), the upper triangular plate 13 is inserted into the lower triangular plate. Stretch in the same direction as 4 (step d).

The pressure of the plate spring 2 prevents the wrapping paper from folding backwards. The string T shown in FIG. 4 connects the paper leading edge presser 1 to the opening/closing arm 108. That is, at the end of folding (step e), the paper leading edge presser 1 is prevented from hanging downward, and the insertion of an inner diameter ring for fixing the wrapping paper, etc. is facilitated.

When the opening/closing arm 108 in FIG. 1 is rotated until the lower triangular plate is in a position substantially parallel to the coil end surface and its upper end is at the outer periphery of the coil end surface, the rotation shown in FIGS. 2 and 3 occurs. By activating the cylinder 8, the upper triangular plate and the lower triangular plate are combined into one body, and the fixing pin 11 is attached to the stopper 1 via the stopper air cylinder 12 and the stopper guide 14.
5 and proceed to step e.

In other words, if the coil diameter and/or width are relatively small, start folding with the upper triangular plate bent at right angles and only the lower triangular plate in contact with the outer periphery of the coil. When the triangular plate 4 is at an angle of approximately 45° to 60° with respect to the coil end surface, the upper triangular plate 13 is extended in the same direction as the lower triangular plate, and the upper and lower triangular plates are connected with the fixing pin 11, so that the upper and lower triangular plates are integrated. Since it is folded while touching the end face of the coil, the upper parts of the press plates do not interfere with each other. Of course, if both the outer diameter and width of the coil are relatively large, the upper and lower press plates can be used as an integrated structure connected from beginning to end.

When the rotary cylinder 107 is rotated, the push plate 110 slides on the end face of the coil and folds the folds formed between the push plates. 15, the upper and lower parts of the press plate are integrated and smoothly slide on the coil end face, so that the generated folds are folded down in an orderly manner, making it possible to package the coil end face beautifully.

(Effects of the Invention) As described in detail regarding the present invention, according to the present invention, when forming pleats for a coil having a large coil diameter and width, a push plate is formed by integrating an upper triangular plate and a lower triangular plate. In order to press and slide the entire coil thickness, and to form pleats in a coil where the coil diameter and/or width are small, the upper triangular plate is bent at the joint with the lower triangular plate, and the lower triangular plate is folded. It is possible to press and slide against the thickness of the coil substantially as a pressing plate, and the wrapping operation of the end face of the coil can be carried out reliably and easily, and its industrial effects are great.
