Abstract

PURPOSE:To completely separate the sheet material by enlarging the clearance by blowing air to the clearance generated in a side edge of its sheet material, when suckers of a line being near one side edge of the sheet material ascend a little in a state that the sheet material of the uppermost part of a stack is sucked by each sucker. CONSTITUTION:In the process for sucking a sheet material from a stack by suckers 12 of plural lines, each sucker is allowed to descend onto the stack and the sheet material of the uppermost part is sucked. Immediately before ascending, the sucker 12a of a line being the nearest to one side edge of the sheet material is allowed to ascend a little by an air cylinder of its sucker itself, and its side edge of its sheet material is raised. By executing an air blow to a clearance generated between its raised side edge and the sheet material thereunder and enlarging the clearance, it is separated surely. In such a way, this method can be used suitably for a carrying system of a common type of a steel sheet and an aluminum sheet.

(Problem to be Solved by the Invention) As described above, the mutual separation of the sheet materials at the top of the stack is performed by a magnetic floater (lO), and therefore the separation of steel sheets can be suitably performed, but the non-magnetic aluminum It cannot be used to separate sheets. On the other hand, in recent years, there has been a significant need to improve the driving performance and fuel efficiency of automobiles, and for this reason aluminum sheets, which are lightweight materials, are being used for automobile body panels. However,
With conventional magnetic floaters, it is impossible to separate the stacked aluminum sheets from each other, and the separation method is a bottleneck in forming the aluminum sheets. It goes without saying that the separation method allows complete separation and is highly reliable, but it also has a simple configuration that can be used in common with steel sheets, and can be used with sheets of various shapes other than rectangles. It is necessary to meet the following requirements.

(Effects of the Invention) As described above, according to the present invention, when the uppermost sheet material on the stack is sucked by the suction cup, one side edge of the sheet material is slightly lifted and air is blown into the gap. The gap is enlarged and separation can be ensured. Furthermore, it can be implemented with a relatively simple configuration, and can be suitably used in a shared conveyance system for steel plate sheets and aluminum sheets, and even when the sheet material has an irregular shape other than a rectangle, such as a triangle or a trapezoid. Can be properly separated. On the other hand, as a common type, as shown in Fig. 7, the upper sheet material is bent using magnetic floaters (10) on both sides, or as shown in Fig. 8, the upper part of the stack is bent using magnetic floaters (10). Although it is conceivable that a rotating brush (30) is provided on the opposite side of the inclined brush to perform air blowing, such a method has the disadvantage that it cannot be used for irregularly shaped sheet materials. However, in order to reduce scrap, irregularly shaped sheet materials are often used, and the inability to accommodate irregular shapes is a fatal drawback, but the present invention can suitably accommodate such irregular shapes. There are advantages.
