2. Description of the Related Art Conventionally, in the manufacturing process of a ventilation duct,
To take out the original plate that is the raw material, a step of unrolling the original plate roll using an uncoiler, correcting the warp with a leveler to make a flat plate state, and then cutting it to a predetermined length by shirring (hereinafter referred to as "the original plate cutting step Is abbreviated as "."). After that, the original plate was moved to a cutting step (hereinafter, abbreviated as “specified cutting step”) for cutting into a prescribed shape using a plasma cutting machine, a laser cutting machine, or the like.

[0003]

By the way, in the manufacture of the ventilation duct, original plates having various plate thicknesses are used depending on the specifications. In this case, there is a method in which, as the original plate that is cut into a predetermined size in advance, it is stacked and stored at a predetermined position beside the processing line for each plate thickness, and the original plate having the required thickness is taken out from the laminated plate and used. However, in this method, since the relatively heavy original plate is taken out by hand one by one, the workability is extremely poor, especially when the number of processed objects is large.

In addition, if a single original plate cutting process was used to replace the original plate roll with a required thickness each time, in a high-mix low-volume production system, a large amount of setup time is required, and this also leads to an increase in production efficiency. There was a problem. Furthermore, in order to solve these problems and quickly respond to high-mix low-volume production, it is necessary to provide a plurality of original plate cutting process lines for each plate thickness and to arrange a prescribed cutting process line for each line. was there. In other words, the original plate cutting process line and the specified cutting process line have a one-to-one correspondence.

However, such a process arrangement not only occupies a lot of space for the original plate cutting process line, but also causes the original plate cutting process line to be idle for a longer period of time than being in operation. There was also a problem in terms of effective use of equipment. This led to an increase in production costs and was a problem in terms of economic efficiency. Therefore, in view of the above problems, the present invention aims to effectively utilize the exclusive space and equipment of the processing line for high-mix low-volume production, and to raise and lower sheet metal plates for the purpose of improving work efficiency. A device is provided.

In addition, and as an auxiliary device of the elevating and accommodating device, there is provided a carry-out conveyor device which is disposed adjacent to the work taking-out side and can easily draw out the works stacked by the air jet.
