  • Patent number: 7153079
    Abstract: In an automated guided vehicle including a transfer equipment which transfers a wafer, a buffer cassette which temporarily stores the wafer, and a pressing member which is provided at an opening of the buffer cassette, when traveling the automated guided vehicle, if the pressing member is slid to a center position from an end position of the opening of the buffer cassette to contact and press against the edge of the wafer, the pressing member was easily damaged by being rubbed against a periphery of the wafer, and there was a problem in durability of the pressing member. The pressing member 55 can transfer between a “pressing” position which contacts against the edge of the wafer 10 to press the wafer 10, and a “receding” position which is located away from the edge of the wafer 10.

  • Patent number: 6394941
    Abstract: The present invention provides a press with an automatic tool changing function which can reduce the amount of time required to change cartridges. A punch press 1 uses cartridges 2 with tools mounted thereon to press works W, and has a change position 7 where the cartridges 2 are changed. A cartridge transferring and loading device 5 is provided which draws out the cartridges 2 from the change position 7 via a linear path L and transfers and loads the cartridges in a cartridge magazine 3 located on an extension of the linear path L. The transferring and loading device 5 has a cartridge moving-in and -out mechanism 19 that moves both forward and backward to transfer and load the cartridges 2 both in the punch press 1 and in the magazine 3.
