Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a threading device for a horizontal continuous furnace for strips, which once extracts the strips downward from the extraction end and then conveys them upwards.

(Prior Art and its Problems) Conventionally, in general, the strip threading method of the horizontal continuous furnace for strips involves charging a threading bar from the furnace charging side, as shown in FIG.
A threading table 2 is provided on the charging side of the horizontal continuous furnace 1 to place the threading bar 3, while a crane 5 is installed on the furnace extraction side to receive the threading bar 3. A threading bar catcher 4 to be operated is provided.

Then, in order to pass the strip S into the furnace 1,
A threading bar 3 is sent from a threading catcher 4 onto a hearth roller 6 of a horizontal continuous furnace to a threading table 2 on the furnace loading side. and,
The threading bar 3 is placed on the threading table 2, the tips of the strips S are connected, and the hearth roller 6 is driven to thread the threading bar 3.
is extracted to the extraction side and received by a threading bar catcher 4, the threading bar 3 is separated from the strip S, the threading bar 3 is moved by a crane 5, and is stored at a predetermined location.

Therefore, the conventional threading apparatus requires sufficient space to install the threading table 2 on the charging side of the furnace 1, and is subject to installation restrictions. Furthermore, there is a problem in that the preparation work, such as preparing the threading catcher 4 using the crane 5 and setting the threading bar 3 on the threading table 2, takes time and effort during the threading work.

This invention eliminates space constraints by eliminating the need for a threading table on the charging side of the furnace, and also eliminates the need for troublesome preparation work when threading. It is an object of the present invention to provide a threading device for a horizontal continuous furnace for stripping, which extracts the strip downward and then conveys the strip upward.

(Means to Solve the Problems) In order to achieve the above object, the threading device for a horizontal continuous furnace for strips according to the present invention has the following features:
A threading bar is provided outside the extraction end of a horizontal continuous furnace for strips, which extracts strips downward from the extraction end and then transports them upwards, and is horizontally rotatable and equipped with a means for transferring the threading bar. A receiving device and a wire drum for winding and unwinding the wire connected to one end of the threading bar are provided, and the threading bar is charged into the furnace from the furnace extraction end side, and the wire drum is connected to one end of the threading bar. It is designed to be taken out from the extraction end side.

(Example) Next, the present invention will be explained with reference to FIGS. 1 and 2, which are one example.

As is clear from the figure, the threading device 7 according to the present invention has a threading bar receiving device 8 horizontally rotatably installed outside the extraction end of the furnace 1, and At the top, a wire 10 is connected to one end of the threading bar 3.
A wire drum 11 wound with a drum is provided so as to be able to come into contact with and separate from a drum rotating means 11a to facilitate maintenance and inspection.

A plurality of driving rollers 9 are provided on the upper surface of the threading bar receiving device 8, and a guide roller 9a is provided above one end of the threading bar receiving device 8. Note that other means may be used instead of the drive roller 9.

Next, a method of operating the threading device 7 having the above configuration will be explained.

First, when passing the strip S,
As shown in FIGS. 1 and 2, the threading bar receiving device 8 is rotated so that the tip of the threading bar 3 faces the opening 1a provided in the furnace 1, and the rollers 9 are driven to remove the threads. The cutting bar 3 is charged into the furnace 1. Note that, with the wire drum 11 in a free state, the wire 10 is connected to the threading bar 3 via the guide roller 9a, and tension is applied to the wire 10 so that the threading bar 3
Prevent meandering.

Therefore, the threading bar 3 is connected to the roller 9.
Thereafter, the hearth roller 6 is driven in reverse to be transported into the furnace with the wire 10 connected, and eventually the tip reaches the charging port of the furnace 1 and stops (the hearth roller 6 stops).

Here, the strip S is connected to the tip of the threading bar 3, and then the hearth roller 6 is driven in normal rotation, the wire drum 11 is rotated, and the threading bar 3 is moved to the furnace extraction side. , winds up the wire 10. When the threading bar 3 is moved onto the threading bar receiving device 8, the rotation of the hearth roller 6 is stopped, and the strip S is separated from the threading bar 3, and the wire 10 and the threading bar 3 are also separated. This completes the threading of the strip S.

After that, the threading bar receiving device 8 is
The strip S from the rising roller 13 of the plating tank 12 is rotated by 90 degrees, that is, perpendicular to the furnace 1.
This is to prevent the material from becoming a hindrance to the upward conveyance of the material, and to prepare for the next threading.

(Effect of the invention) As is clear from the above explanation, according to the invention, the threading bar is made to stand by outside the extraction end of the furnace, and there is no space for threading on the charging side of the furnace. Moreover, since the threading device normally rotates and does not interfere with the conveyance of slips, there are no restrictions on the installation of the threading device.

However, since the threading bar reciprocates between the furnace extraction end and the charging side, and the preparation work involved simply connecting the threading bar and the strip, the work efficiency is low. This is much better than the conventional one.
