DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production line for continuously producing various products from a band-shaped metal material wound in a coil shape, for example, a press for mass-producing lead frames and chassis from a band-shaped metal material. Each is installed on a line or a pipe-making line for mass-producing pipes from metal strips, and the end of the metal strip being processed is joined to the start of a new metal strip by butt welding. The present invention relates to a band-shaped metal material joining apparatus capable of continuously flowing a metal material onto a line, and particularly to satisfactorily and surely join a terminal end portion and a start end portion of the band-shaped metal material regardless of a conveying posture of the band-shaped metal material. The present invention relates to a strip-shaped metal material joining apparatus.

[0002]

2. Description of the Related Art In general, as a production line for continuously processing a strip-shaped metal material wound in a coil shape to continuously produce various products, there is a press line for producing a lead frame or the like. The line is known.

[0003] That is, although not shown, the press line includes an uncoiler (unwinding device) for supporting a strip-shaped metal material wound in a coil shape so as to be able to pay out and rotate freely, and a winding habit of the strip-shaped metal material. A leveler (straightening device) to take and a press device for processing a band-shaped metal material are arranged in series, and the band-shaped metal material fed from the uncoiler is fed into a press device such as a roll feed or the like (or an independent device). The feeder is fed to the leveler by a feeder, which removes the curl of the band-shaped metal material, and then continuously supplies it to the press, so that various products such as lead frames can be mass-produced. I have.

[0004] By the way, in the play line,
When the band-shaped metal material attached to the uncoiler runs out,
A new band-shaped metal material is newly attached to the decoiler, and the starting end of the new band-shaped metal material is pulled out from the uncoiler and manually passed through a leveler, a press device, and the like.

[0005] However, passing the band-shaped metal material through a leveler, a press device, or the like is an extremely time-consuming operation.
There is a problem that considerable loss time occurs before each device can be operated again. In particular, when a progressive die is used or when a plurality of press devices are installed, the above problem is further promoted.

In view of the above, a material joining apparatus in which an end portion of a band-shaped metal material which has been conventionally processed and a start end portion of a new band-shaped metal material are joined by welding so that the band-shaped metal material can be continuously supplied to a press device or the like. (For example, the device disclosed in Japanese Utility Model Publication No. 1-13822) has been developed and put to practical use.

That is, the material bonding apparatus D is installed between an uncoiler (not shown) and a leveler (not shown) in a press line, and as shown in FIG. 7 and FIG. A transport base 33, a high-speed transport base 34, a cutting device 35, a holding device 36, a welding device 37, and a rolling device 38 are mounted on a frame 32 mounted on a guide rail 31.
And the frame 32 is attached to the cylinder 39.
Thereby, it is possible to move along the guide rail 31.

[0008] During the pressing of the strip-shaped metal material a, the strip-shaped metal material a fed from the uncoiler is used.
Are transported on the high-speed transport base 34 of the material bonding apparatus D and are continuously supplied to a press device or the like, where they are sequentially pressed.

On the other hand, when the band-shaped metal material a supported by the uncoiler runs out and the end of the band-shaped metal material a approaches the material joining device D, the feeding and pressing device of the band-shaped metal material a are stopped, and a new one is stopped. The strip-shaped metal material a is mounted on the uncoiler, and its starting end is pulled out onto the high-speed transport base 34 of the material bonding device D.

Next, the frame 32 is advanced by the cylinder 39, and the end portion of the band-shaped metal material a being processed and the start end portion of the new band-shaped metal material a are placed on the transport base 33 of the material joining device D. Thereafter, the end portion and the start end of the strip-shaped metal material a are cut by the cutting device 35, respectively, and the cut end of the end portion and the start end of the strip-shaped metal material a are welded by the pressing device 36 to the welding torch 40 of the welding device 37. Are butt-fixed in a butt state immediately below the butt portion, and butt-welded by a welding device 37.

When the butt welding of the strip-shaped metal members a is completed, the welded portion is moved to a position immediately below the rolling device 38 and rolled by the rollers 41 of the rolling device 38 so as to be uniform. Retreated,
The bonded strip-shaped metal material a is placed on the high-speed transport base 34. In this state, the leveler, the press device and the like are restarted, and the new band-shaped metal material a mounted on the decoiler is continuously supplied to the press device and the like.

Therefore, if the material bonding apparatus D is installed in a press line, it is not necessary to manually pass a new band-shaped metal material a mounted on the decoiler to a leveler, a press apparatus, or the like, and the downtime of the press apparatus is greatly reduced. Can be shortened.

[0013]

By the way, the band-shaped metal material a sent from the uncoiler to the leveler is not always conveyed in a fixed posture (for example, a horizontal posture), but is formed in a space between the uncoiler and the leveler or in a coil shape. Depending on the outer diameter or the like of the wound metal strip a, the strip-shaped metal material a may be conveyed in an inclined position (an upwardly inclined position that becomes gradually higher in the conveying direction or a downwardly inclined position that becomes lower in the conveying direction). .

However, in the conventional material bonding apparatus D, since the band-shaped metal members a are butt-welded to each other in a horizontal posture, the band-shaped metal members a are conveyed in an inclined posture. If it is installed in a place where it is located, it may not be possible to join the band-shaped metal materials a,
A problem arises that it cannot be used.
When the thickness of the strip-shaped metal material a is extremely small, even if the strip-shaped metal material a is conveyed in an inclined position, the strip-shaped metal material a is bent to a horizontal position by bending the strip-shaped metal material a itself. Therefore, the strip-shaped metal material a can be passed through the material joining device D. In this case, the band-shaped metal members a may be joined to each other by using the material bonding device D in some cases. However, when the thickness of the band-shaped metal material a is slightly increased, the band-shaped metal material a itself cannot be bent, and the band-shaped metal material a cannot be passed through the material joining device D.
In this case, the material bonding device D cannot be used after all.

Further, in the conventional material bonding apparatus D, a cutting device 35, a holding device 36, a welding device 3
7 and the rolling devices 38 are arranged in a horizontal row.
Since the entire apparatus moves back and forth, there is a problem that the apparatus itself becomes extremely large and a large installation space is required. As a result, when a sufficient space cannot be secured between the uncoiler and the leveler, the material bonding device D may not be able to be installed.

The present invention has been made in view of the above problems, and an object of the present invention is to ensure that the metal strips can be reliably and satisfactorily joined to each other irrespective of the conveying posture and the sheet thickness of the metal strips. Another object of the present invention is to provide a band-shaped metal material joining apparatus which can be installed easily and easily in a place where sufficient installation space cannot be obtained or in existing facilities.

After the end of the strip-shaped metal material a is cut, the table 3 is manually advanced from the storage position onto the transport line of the strip-shaped metal material a, and the height adjustment mechanism 9 and the angle adjustment mechanism 17 are respectively operated. Then, the height and angle of the table 3 are adjusted such that the upper surface of the table 3 is positioned below the respective band-shaped metal members a and the upper surface of the table 3 is parallel to the band-shaped metal members a. That is, the table 3 is in the working position (FIG. 3).
(Solid line position), and the end of the band-shaped metal material a being processed and the start end of the new band-shaped metal material a are placed on the upper surface of the table 3.

And the table 3 provided with the welding device 5 and the like is adjustable in height and angle, so that the belt-shaped metal material a is conveyed in an inclined posture or a horizontal posture, or the belt-shaped metal material a
By adjusting the height and angle of the table 3, the band-shaped metal member a can be reliably mounted on the upper surface of the table 3 even if the band-shaped metal member a itself cannot be bent due to the large thickness of the band. it can. As a result, the terminal end and the start end of the strip-shaped metal material a can be securely and satisfactorily butt-welded irrespective of the conveying posture and the plate thickness of the strip-shaped metal material a. For example, when the band-shaped metal material a is in the inclined posture, the angle of the table 3 is adjusted as shown in FIG. 5 and FIG. You can put in. In addition, the table 3 has minimum necessary devices (a holding device 4 and a welding device 5).
), The device itself can be significantly reduced in size. As a result, even when a wide space is not required and a sufficient space cannot be secured between the uncoiler B and the leveler feed C, the band-shaped metal material joining apparatus A can be installed between the uncoiler B and the leveler feed C. it can. Needless to say, since the table 3 where the presser device 4 and the welding device 5 are disposed can take the storage position and the work position, the installation space is smaller than that of the conventional device in which the entire device moves. I can do it.

In the above-described embodiment, a manual height adjustment mechanism 9 is provided between the fixed frame 7 and the elevating frame 8, and the height of the main body 1 is adjusted manually.

[0055]

As described above, the band-shaped metal material joining apparatus of the present invention comprises a table provided with a holding device, a welding device, and the like.
Because it is configured to be rotatable and angle-adjustable on the upper end of the height-adjustable main body, when the strip-shaped metal material is transported in an inclined posture or a horizontal posture, or when the thickness of the strip-shaped metal material is large, Even when the band-shaped metal material itself cannot be bent, the table can be satisfactorily and reliably conformed to the band-shaped metal material by adjusting the height and angle of the table. That is, the band-shaped metal material can be reliably mounted on the table upper surface in a favorable posture. As a result, the terminal end of the band-shaped metal material being processed and the start end of the new band-shaped metal material can be reliably and satisfactorily welded irrespective of the conveying posture and the sheet thickness of the band-shaped metal material.
