  • Patent number: 6510365
    Abstract: The invention is a method for positioning a conveying mechanism having a holding portion for semiconductor wafers. Respective provisional position coordinates of an orienting teaching standard position and a container teaching standard positions are inputted into a controlling unit in advance. A wafer to be conveyed precisely positioned with respect to and held by the holding portion is conveyed and placed on the rotating orienting device according a control based on the provisional coordinates of the orienting teaching standard position. A posture detector then detects the eccentric volume and eccentric direction of the wafer. Appropriate position coordinates are made by amending the provisional coordinates. Then, a wafer to be conveyed precisely positioned with respect to the container teaching standard position is conveyed and placed on the rotating orienting device according a control based on the provisional coordinates of the orienting teaching standard position.

  • Patent number: 6499980
    Abstract: An automated conveyance system moves green tires (24) with monorail carriers (18) to tire molding presses (40). Each monorail carrier (18) deposits a green tire (24) into an elevator system (31) which, in turn, transfers the green tire to within reach of a press loader (38) for tire press (40). The elevator system (31) also provides a buffer storage for the tires in process. In one embodiment, the green tire in the basket (28) is rotated about a vertical path through which the basket moves to within reach of the press loader. In another embodiment, the elevator system (31) can move the green tire by linear translation from the vertical path through which the basket moves to within reach of the loader (38).

The isolated bolt is picked up by a robot that has been taught how to pick up an isolated bolt laying in a standard position. The position of the robot's hand is corrected according to the deviation from the standard position before the robot attempts to pick up the located isolated bolt. If no isolated bolt is found, a shaking device 1 is operated to loosen the piled-up bolts, and a new isolated bolt is again searched for by the visual sensor. The isolated bolt, if found, is picked up. The picking-up operation may be performed by searching for an isolated small set of bolts using a three-dimensional visual sensor.

The wafer handling chamber has a wafer aligner, or orienter, for aligning the wafers according to the requirements of a process that the wafer is to undergo in the system. The wafer aligner is disposed at a location in the wafer handling chamber to minimize the number of movements that the wafer makes as it passes through the wafer handling chamber, to minimize interference between wafer handlers, or robots, when more than one wafer handler is used in the wafer handling chamber and to minimize the footprint area of the system.

An assessment device automatically assesses the read shipping addresses. The individual shipping articles are selectively deposited into cells of an intermediate storage device disposed in the transport path following the reading of the shipping address. A detection device detects an association between each cell and the shipping article deposited therein and in response to an assessment of the shipping address by the assessment device, produces a first removal signal for removing the shipping article from the cell and conveying the shipping article back to the transport path.
