[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel plate drilling device in a shearing line.

[0002]

2. Description of the Related Art In a shearing line for a surface-treated steel sheet such as a tin-plated or chromium-plated steel sheet, non-defective products and defective products are sorted according to the degree of surface scratches, pinholes and the like of the steel plate. Further, defective products are usually classified into heavy defective products and light defective products.

[0003] This shearing line will be described with reference to FIG. The steel sheet S rewound by the payoff reel 1 is connected to the preceding steel sheet S ′ and the succeeding steel sheet S by the welder 2, and is trimmed by the side trimmer 3. After that, inspection for surface flaws, pinholes, etc. is performed by the inspection device 4, the shape is corrected by the leveler 5, and sheared to a predetermined size by the shearing machine 6. Next, sorting is performed by a sorting device 7, 7 ', 7 "formed by a magnet roll. A heavy defective product is in the pillar 8, a light defective product is in the pillar 8', a good product is in the pillar 9,
9 '.

[0004] In the above line, the sorting device 7,
Sorting by 7 ', 7 "is performed based on the inspection result in the inspection device 4. In particular, among the inspection devices 4, erroneous determination of the pinhole detection device, or the sorting device 7, 7',
7 "malfunction may occur. In this case, a defective product is mixed in a non-defective product or a non-defective product is mixed in a defective product. Is a big problem.

[0005]

Therefore, in order to prevent the above-mentioned erroneous determination or malfunction, a pinhole was intentionally drilled in the steel plate once per hour or so, and it was checked whether or not the equipment normally operates. . The pinhole was drilled by holding an L-shaped metal fitting with a sharp tip and hitting a running steel plate, or using a simple manual drilling device.

[0006] In this work, if the timing is bad, there is a danger that the metal fittings will be carried along with the movement of the steel plate.
In addition, there is a problem in safety because the work is performed close to the line, and thus improvement has been desired.

Japanese Unexamined Utility Model Publication No. 60-66626 discloses a drilling device. In this device, by pinching a steel plate being passed at high speed with a stationary roll,
Since the roll with the needle rotates and drills holes in the steel sheet, a slip condition occurs until the roll touches the steel sheet and rotates at the same speed as the steel sheet, which may cause scratches on the steel sheet. In addition, because the holes are formed by rotating the rolls on the steel plate running at high speed, it is difficult to control the rolls to rotate at high speed to make only one hole, and furthermore, the standby position of the needle cannot be determined. is there.

[0008] It is an object of the present invention to provide a steel plate drilling device in a shearing line that can solve the above-mentioned problems.

[0009]

SUMMARY OF THE INVENTION The gist of the present invention is to provide an arm (1) provided to be swingable toward the surface of a traveling steel plate (S).
8), a pin holder (23) provided at the tip of the arm (18) so as to be rotatable in the traveling direction of the steel plate, a needle (24) provided at a tip of the pin holder (23), and the arm (18). 18) a set weight for providing a counterweight (27) at the rear end of the pin holder (23) and receiving the rotation of the pin holder (23) by the counterweight (27). (28) provided at the distal end of the arm (18), the needle by swinging towards the steel surface of the arm (18) (24) pierces the traveling steel sheet in a direction away from the steel sheet surface of the arm (18) before swinging, steel punch apparatus at a shear line Pinporuda (23) is characterized in that so as to rotate in the steel sheet running direction by the traveling of the steel sheet.

[0010]

The operation of the present invention will be described in detail with reference to the embodiments shown in the drawings.

As shown in FIG. 3, a gantry 10 is installed in a line vertical path or a free loop portion (portion indicated by A in FIG. 5), a traverse beam 11 is fixed on an upper portion of the gantry 10, and a linear The gantry 13 is installed via the ball bearing 12. A cylinder 14 is mounted on the base 13,
The V-shaped bracket 16, the guide rail 17 and the amplification arm bearing 19 are fixed.

Clevis 20 at the end of cylinder and V-shaped bracket 1
5, the link 21, the wheeled link 22, the amplifying arm 18 and the pin holder 23 are pin-coupled, and the linear motion is converted into an arc-shaped motion by the V-shaped bracket 15 by projecting the clevis 20 at the cylinder end. Link 21,
It is converted into a linear reciprocating motion by the link with wheels 22 and the guide rail 17. The reciprocating motion of the wheeled link 22 has a short stroke.
8 amplifies the stroke.

The drilling mechanism will be described in detail. The arm 18 is extended forward near the center of the cylinder stroke (FIG. 1B), and a hole is drilled in the steel plate by the needle 24 attached to the tip of the pin holder 23. At the moment when the needle 24 pierces the steel plate S, the needle 24 is dragged by the steel plate S and escapes around the bearing 25 of the pin holder 23 (FIG. 2), and the entire arm 18 also escapes backward. (FIG. 1C), small holes are drilled even when the steel sheet S runs at high speed. The pin holder 23 is provided with a counterweight 27. When no force is applied to the needle 24, the pin holder 23 is always in a state before drilling a hole. The entry angle of the needle 24 can be arbitrarily adjusted with a set bolt 28. This completes one drilling operation,
Next, in order to perform the drilling operation, the same operation (the operation in FIGS. 1C to 1A) is performed by retracting the cylinder 14.

FIG. 4 is a plan view of FIG. 3, and shows that a hole is made at an arbitrary position of the steel plate by moving the traverse cylinder 26 to the position (a) to (c) or the like. Further, by providing several limit switches, it is possible to open a hole at a fixed position in the width direction of the steel sheet.

[0015]

[Effects of the Invention] The present invention allows the work to be performed safely because the cylinder can be pierced by remotely inserting and removing the cylinder when necessary, and the work can be performed safely. The moment the needle is stabbed, the needle escapes instantly, creating a small hole. Furthermore, once the arm has escaped, it will not approach the steel plate unless the drive device is operated, and only one hole is surely lit by one operation,
Prevent waste of steel plate.
