Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a threading device for passing a strip on a strip transport line when the transport is started or when the strip is cut.

[0002]

[Prior Art]

 If the strip produced by the continuous rolling machine is continuously processed after the rolling process or after rewinding the coil once wound and various processing devices such as a cleaning device, a heat treatment device such as annealing, and a plating device, are processed. Strips need to be transported horizontally over long distances before and after the machine. As a transport line for this transport, generally, a transport line in which a plurality of lower rollers that support the lower surface of the strip and an upper roller that regulates the upper surface of the strip are arranged side by side along the transport path. It is used.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned transfer line, when it is attempted to pass the plate at the start of transfer or when the plate is cut, a stitch is formed between the upper roller and the lower roller that are arranged above and below the transfer path. Since it is difficult to perform automatic threading, it is unavoidable to manually thread the wire, or manually pass the wire through the wire and connect the end of the strip to this wire, and then pull the wire to thread it. However, it took a lot of effort and time. Especially when the transfer line is formed on the lower side of the work floor, it becomes a high place operation with the lower floor as a scaffolding, which is unfavorable for safety.

The present invention solves the above-mentioned conventional problems, and provides a stripping device for a strip transfer line that can automatically perform plate passing by using a mechanical device and can achieve labor saving and shortening of the plate passing time. Is what you are trying to do.

[0005]

A striping device for a strip transport line according to the present invention comprises a plurality of lower rollers that support the lower surface of the strip and an upper roller that regulates the upper surface of the strip. In the strip transfer line installed side by side, the upper roller can be retracted to the side of the transfer path, and a trolley that is driven in the strip transfer direction is provided above the transfer path, and the tip of the strip is attached to this trolley. It is characterized in that a connecting tool for connection is provided.

[0006]

[Action]

 In the threading device of the present invention, if the upper roller is retracted to the side of the transfer line, there will be no obstruction above the transfer path of the strip. At the entrance of the transport path, the tip of the strip is connected to the trolley connector by a wire and the trolley is driven in the transport direction of the strip, and the strip is guided by the lower roller while the lower roller is being guided. -Proceed above La and go through the plate. After passing the plate, by returning the upper roller to the position on the conveying line, the upper roller can regulate the upper surface of the strip and normally convey the strip.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, 1 is a strip conveying line, and a plurality of lower rollers 3 for supporting the lower surface of the strip 2 and upper rollers 4 for regulating the upper surface thereof are arranged in parallel along a conveying path 5. Consists of The lower roller 3 is rotatably supported by a bearing 6 fixed on the foundation.

A bearing 7 that rotatably supports the upper roller 4 is fixedly attached to an arm 8 that is rotatable about a vertical axis. Reference numeral 9 denotes a support shaft that rotatably supports the base of the arm 8 and is fixed to a ceiling 10 above the transport path 5 at a position lateral to the strip transport path 5. Reference numeral 11 denotes an air cylinder which is a swing drive device for the arm 8. The air cylinder 11 is supported on the ceiling 10 by a bracket 12, and its piston rod 13 is connected to the tip of a lever 14 fixed to the arm 8. Numeral 15 is a stopper which engages with the tip of the arm 8 and positions the axis of the upper roller 4 at right angles to the transport direction of the strip, and is fixed to the ceiling 10.

A guide rail 20 is fixed to the ceiling 10 immediately above the transport path 5 and is provided along the transport path 5 from the entrance portion 5a to the exit portion 5b of the transport path 5. 1 is supported by the guide rail 20 so as to be reciprocally movable. Reference numeral 22 denotes a reciprocating drive device for the trolley-21, which is provided with a trolley at both ends of a wire rope 25 wound around a drive rope wheel 23 driven by a motor (not shown) and a driven rope wheel 24. It is connected to -21. Numeral 26 is a hook-shaped connector fixed to the lower surface of the trolley-21.

In the threading device 30 having the above-described structure, the air cylinder 11 drives the arms 8 and the upper roller 4 in a swiveling manner as indicated by an arrow R in FIG. To the retreat position indicated by the chain line 31. Then, the wire 32 connected to the tip of the slip 2 to be threaded at the entrance 5a of the transport path 5 is hooked on the connector 26 of the trolley-21 stopped at a position near the entrance 5a. When the trolley 21 is driven by the reciprocating drive device 22 in the transport direction indicated by the arrow X, there are no obstacles such as the upper roller 4 and the arm 8 on the transport path 5, so that the strip 2 is moved downward. It can be passed over the roller 3.

When the tip portion of the strip 2 reaches the outlet portion 5b of the transport path 5, the wire 32 is detached from the connecting tool 26, and is used as a threading plate for a processing device or the like in the next step. When the arm 8 is returned to the position shown by the solid line in FIG. 3 by the air cylinder 11, the upper roller 4 returns to the normal transfer position and cooperates with the lower roller 3 to make the strip normal. It can be transported.

As described above, the strip 2 can be automatically threaded by simply manually engaging and disengaging the tip end of the strip 2 with respect to the coupling tool 26, and can be quickly threaded over long distances. It can be done easily.

The present invention is not limited to the above embodiment, and for example, the swing drive device of the arm 8 and the reciprocating drive device of the trolley-21 may be of a type other than the above. Further, the upper roller 4 is swung around the vertical axis as described above to be retracted to the side of the conveying path, and is also conveyed by using a linear mechanism for retracting and projecting in a direction perpendicular to the strip conveying direction. It may be configured to be retracted to the side of the road.

[Effect of the device]

 As described above, according to the present invention, it is possible to automatically pass the strip in the strip transfer line by using a mechanical device, and it is possible to achieve labor saving and reduction of the stripping time.
