BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threading apparatus for threading a strip on a strip transfer line at the start of transfer or when the plate is cut.

[0002]

2. Description of the Related Art Strips manufactured by a continuous rolling device are continuously processed by a variety of processing devices such as a cleaning device, a heat treatment device such as annealing, and a plating device following a rolling process or by unwinding a coil once wound. If you do
It is necessary to transport the strip horizontally over a long distance before and after the processing device. As a transfer line for this transfer, a transfer line is generally used in which a plurality of lower rollers supporting the lower surface of the strip and upper rollers controlling the upper surface of the strip are arranged in parallel along the transfer path. ing.

[0003]

However, in the above-mentioned transfer line, if it is attempted to pass the sheet at the start of the transfer or when the plate is cut, the upper rollers provided on the upper and lower sides of the transfer path and the lower roller are provided. Since it is necessary to pass through the side rollers in a sewn form, it is difficult to pass the strip automatically, and it is unavoidable to pass the strip manually or to connect the end of the strip to this wire by hand. However, since the wire was pulled and passed, a great deal of labor and time were required. In particular, when the transfer line is formed below the work floor, the work is performed at a high place using the lower floor as a foothold, which is not preferable in terms of safety.

[0004] This invention solves the above-mentioned conventional problems, and provides a threading device for a strip transport line which can automatically pass a sheet using a mechanical device, and can achieve labor saving and shortening of a sheet passing time. It is assumed that.

[0005]

According to the present invention, a stripping device for a strip transfer line comprises a plurality of lower rollers for supporting the lower surface of the strip and upper rollers for regulating the upper surface of the strip along a transfer path. In this strip transport line, the upper roller can be retracted to the side of the transport path, and a trolley driven in the strip transport direction is provided above the transport path. A connection tool for providing the same.

[0006]

In the threading device of the present invention, if the upper roller is retracted to the side of the transport line, there is no obstacle above the transport path of the strip. At the entrance of the transport path, the tip of the strip is
When the trolley is driven in the transport direction of the strip, the strip advances on the lower roller while being guided by the lower roller, and the sheet is passed. If the upper roller is returned to a position on the transport line after the passage, the strip can be normally transported while the upper surface of the strip is regulated by the upper roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the drawing, reference numeral 1 denotes a strip transport 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 are arranged in parallel along the transport path 5. Become. The lower roller 3 is rotatably supported by a bearing 6 fixed on a foundation.

A bearing 7 for rotatably supporting the upper roller 4
Is fixedly mounted on an arm 8 which is pivotable about a vertical axis. Reference numeral 9 denotes a support shaft for rotatably supporting the base of the arm 8, which is fixed to a ceiling 10 above the transport path 5 at a position lateral to the transport path 5 for the strip. Reference numeral 11 denotes an air cylinder which is a turning drive device of the arm 8, and a bracket 1
2 supported on the ceiling 10 and its piston rod 13
Is connected to the tip of a lever 14 fixed to the arm 8. Reference numeral 15 denotes a stopper which engages with the tip of the arm 8 to position the axis of the upper roller 4 at right angles to the strip transport direction, and is fixed to the ceiling 10.

Reference numeral 20 denotes a guide rail fixed to the ceiling 10 immediately above the transport path 5 and is provided along the transport path 5 from the entrance 5a to the exit 5b of the transport path 5, and a trolley-21. Are reciprocally supported by the guide rail 20. Reference numeral 22 denotes a reciprocating drive unit for the trolley 21. 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 are connected to the trolley. -21. Reference numeral 26 denotes a hook-shaped connecting member fixed to the lower surface of the trolley 21.

In the threading device 30 having the above-described structure, the arm 8 and the upper roller 4 are turned by the air cylinder 11 as shown by an arrow R in FIG. And stopped at the retracted position indicated by the chain line 31. Then, the wire 32 connected to the tip of the slip 2 to be passed through at the entrance 5a of the transport path 5 is
The trolley 21 is stopped at a position near the entrance 5a and is hooked on the connecting member 26. When the trolley 21 is driven by the reciprocating drive device 22 in the transport direction indicated by the arrow X, since there is no obstacle such as the upper roller 4 and the arm 8 on the transport path 5, the strip 2 is moved downward. It can be passed over the roller 3.

When the leading end of the strip 2 reaches the outlet 5b of the transport path 5, the wire 32 is removed from the connecting member 26, and the strip 32 is supplied to a plate of a processing apparatus 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 perform normal transfer of the strip. Can be performed.

In this way, the strip 2 can be automatically threaded by simply removing the tip of the strip 2 from the connecting member 26 by hand, and the threading can be quickly and easily performed over a long distance. Can do it.

The present invention is not limited to the above-described embodiment. For example, the turning drive of the arm 8 or the trolley-2
The one reciprocating drive device may be of a type other than the above. The upper roller 4 is conveyed by using a linear motion mechanism or the like that is turned around the vertical axis line to retract to the side of the conveyance path as described above, and is also drawn in and projected in a direction perpendicular to the strip conveyance direction. It may be configured to retreat to the side of the road.

[0014]

[Effect of the invention] As described above, according to the invention,
In the strip transfer line, the sheet can be automatically passed using a mechanical device, so that labor saving and shortening of the sheet passing time can be achieved.
