2. Description of the Related Art A material plate feeding device for a press machine is a device for feeding a metal material plate wound in a coil shape to a press machine after correcting its winding habit. There is a down loop type uncoiler device from which the coiled material plate is pulled out from below, a leveler device for correcting the winding habit of the material plate drawn from this uncoiler device, and between the uncoiler device and the leveler device. When the coil body is newly mounted on the uncoiler device,
A material plate insertion device is provided for guiding and inserting a tip end of the material plate pulled out from the mounted coil body into the leveler device.

There are various types of material plate insertion devices. For example, two support arms are arranged between an uncoiler device and a leveler device, separated by the width of the material plate, and a roll is inserted between the two. And the lower end of each of the two support arms is rotatably mounted on a leveler device. The material plate pulled out of the uncoiler device is guided between the two support arms , and the support arm rotates while pressing the material plate with a roll between the support arms, and guides the material plate to the leveler device.

As another material plate insertion device, as described in Japanese Patent Application Laid-Open No. H2-220712, a device is provided between an uncoiler device and a leveler device to tilt between the uncoiler device and the leveler device. Some have an outer package arranged apart from each other, and a feed roll mechanism mounted between the two outer packages. This feed roll mechanism includes a fixed roll, and an opening / closing roll that approaches or separates from one side of the fixed roll.The fixed roll includes a front protruding piece that rotates like a seesaw around the fixed roll.
