Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is continuous with a drawing device in a lead-out portion of a belt-shaped processing machine, and folds a band that has been treated into a carrier truck placed on a floor. The present invention relates to a shake-off device for overlapping and shaking-off.

[Prior Art] As a device for shaking off a belt, a horizontally swingable belt guide plate is provided below the final guide roller, and the belt guided by the final guide roller is fed downward. The object guide plate is passed through, and the swinging motion of the object guide plate tends to cause it to fall into the carriage for carrying the belt-like object placed on the floor of the belt-like object.

[Problems to be Solved by the Invention] However, in the shake-off device of the related art, since the belt-like material is simply shaken-off, the seam of the belt-like material is the same as that of the other parts. Can be folded into. From this state, that is, it is very troublesome to search for a seam in many folded strips.

Further, if the seam is to be taken out of the transportation trolley before the seam enters the transportation trolley, a monitoring staff for the seam is required. Then, when the surveillance staff member finds the seam, it is very inefficient to take the seam out of the transport cart and to take it out, and there is also a problem that a drawing error occurs due to an oversight.

[Means for Solving Problems] Therefore, the following means were taken to solve the above problems.

In the shake-off device of the present invention, a drawer for drawing out the treated strip is installed at the outlet of the heat treatment machine, and a final guide roller for guiding the strip is arranged near the exit of the drawer, Below the final guide roller, there are provided a pair of opposing strip-shaped material guide plates that swing horizontally, and the strip-shaped material that is fed from the drawing device and then guided to the final guide roller is formed into the pair of strip-shaped material. In a belt-like object shaker configured to shake downward through an object guide plate, a point detection sensor for detecting a belt-like joint or a mark is provided on the belt-like object supply side of the final guide roller. At least one guide plate of the pair of inner strip guide plates has a two-layer structure of a fixed guide and a moving guide plate, the fixed guide plate is supported by a shake-off device, and the moving guide plate is lowered along the fixed guide plate. The movable guide plate slides downward in accordance with the detection of the seam or mark of the band by the point detection sensor, and the swinging width of the band is expanded. -It is designed such that the part of the black can be pulled out to the outside of the trolley for carrying the belt.

[Operation] In the shake-off device of the present invention, the processed belt-like material is sent out from the drawing device of the outlet of the processing machine. Then, this strip is guided by a final roller arranged near the outlet of the drawing device to a pair of opposing strip guide plates provided below the final roller. Since the strip-shaped material guide plate is swingable in the horizontal direction, the strip-shaped material that passes through the strip-shaped material guide plate swings along with this reciprocating motion. As a result, the strip is shaken off and folded into the strip-carrying truck placed on the floor.

Further, when a seam or a mark attached in advance reaches the point detection sensor provided on the band supply side of the final roller, the seam or mark is detected by this point detection sensor. To be done. With this detection, the moving guide plate forming the strip-shaped object guide plate slides downward along the fixed guide plate. In response to this, the length of the strip guide plate in the strip advancing direction increases and the swinging width of the strip increases, and the seams and marks on the strip are automatically removed from the carriage for transporting the strip. Can be shaken off.
