Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pretreatment device for strip coils on the entry side of a metal strip treatment line.

[Conventional technology]

In the past, in various metal strip processing lines, it was necessary to manually supply the strip coils to the input side of the line. That is, the binding bands of the coils placed in the coil storage area were cut and removed using a cutter or the like, and then transported by an overhead crane or the like to the coil car on the line entry side and placed on the coil car. When placing this coil, it was necessary to take care to consider the orientation of the coil and to place it in the center of the coil car.

[Problem that the invention seeks to solve]

The object of the present invention is to provide a pretreatment device that automates the coil handling at the input side of these lines, thereby saving labor and improving productivity.

[Means for solving problems]

FIGS. 1a and 1b show a plan view and a side view of the overall arrangement of a strip coil pretreatment device on the entrance side of a metal strip treatment line according to an embodiment of the present invention.
The present invention will be specifically explained below with reference to FIG.
Move the coil C from the left side of the diagram to the right side of the coil skid 2.
Walking beam 1 that conveys pitches over 3 positions of a to 2e and turntable 7
Place. The walking beam 1 has at least three coil skids. The first coil skid 2 of these three or more coil skids
An end detection device 8 is arranged at b. The end detection device 8 detects the position and winding direction of the coil end, and uses, for example, an optical sensor. The coil skid 2b is equipped with a cradle roll 3. The cradle roll 3 receives a signal from the end detection device 8 and automatically rotates the coil in the winding direction. This rotation is caused by the following bundt cutting process.
To prevent the cutter head of the band cutter 5 from interfering with the coil end and making cutting impossible, the band cutter 5 is rotated until the coil end position is at the bottom of the coil. The second coil skid 2d has a steel band 6 tied at any position on the outer circumference of the coil.
A band position detection device 4 is provided to detect the position of the band. A band cutter 5 is provided on the third coil skid 2e, and the coil skid 2e is movable. This coil skid 2e is moved laterally so that the band position and skid groove are aligned. The band cutter 5 is moved horizontally in advance so that the center of the cutter head is aligned with the band position and is on standby. The band cutter 5 cuts the band bound at any position on the outer periphery of the coil when the coil is transported to the position.

A turntable 7 is arranged on the downstream side of the walking beam 1. The turn tail 7 aligns the conveyed coil with the threading direction in the line and horizontally
Rotate 90°. The direction of rotation at this time is automatically determined in response to a signal indicating the coil winding direction detected by the end detection device 8 of the coil skid 2b, and the coil skid 2b is rotated.

Next, a transfer car 9 is installed to move the coil to the center position of the payoff reel on the processing line. The transfer car 9 sends the coil to the center of a predetermined payoff reel 10, 11, and each coil car (not shown) attaches the coil C to the payoff reel 10, 11 in the line, respectively.

Reference numeral 12 indicates the center of the strip processing line, and the coils inserted into the payoff reels 10 and 11 are unwound and sent in the direction of arrow A to undergo various treatments such as pickling.

[Effect]

As described above, the present invention includes a coil end detection device,
Coils can be automatically loaded into the processing line by combining and arranging the coil rotation device, band position detection, coil skid shift, band cutter, and turntable devices.

〔Effect of the invention〕

According to the present invention, the conventional troublesome inlet coil handling can be automated. Therefore, great effects such as labor saving, productivity improvement, and safety improvement can be obtained.
