| 20120128455 | TRANSPORT SYSTEM AND STORAGE DEVICE - In a transport system, two drop prevention barriers and a drop prevention mechanism are provided along a periphery of a load port where a transported article has been placed. The drop prevention barriers and the drop prevention mechanism are arranged on three sides around the periphery of the load port and a remaining side is open along a first direction. The drop preventing mechanism includes a retaining member rotatably supported on a bracket. When a transported article moves along the first direction, the retaining member is pushed by a transport device such that it rotates from an initial position and retracts in an opposite direction from where a path is located. When the transported article has been loaded onto the load port, the retaining member returns to the initial position such that it is arranged slightly above the transported article. | 05-24-2012 |
| 20120128452 | TRANSPORT SYSTEM AND SET-UP METHOD - In a transport system, a positioning hole is provided in an undersurface of a container. A positioning protrusion corresponding to the positioning hole of the container provided on a first load port of a manufacturing device. When a transport vehicle places the container onto the first load port, the placement position of the container is established by having the positioning protrusion of the first load port fit into the positioning hole. A second load port different from the first load port of the manufacturing device is provided on a storage device. A positioning protrusion is not provided on the second load port. A slip prevention member is provided on an upper surface of the second loading load port. | 05-24-2012 |
| 20120114453 | TRANSPORT SYSTEM AND TRANSPORT METHOD - In a transport system, a local track is disposed so as to be below an overhead travelling vehicle track in parallel or substantially in parallel therewith, and furthermore above a loading port of a processing device from upstream of the loading port to downstream of the loading port. A local vehicle including a hoist travels along the local track. Below the local track, a first buffer is disposed upstream of the loading port of the processing device, and a second buffer is disposed downstream of the loading port of the processing device, and the overhead travelling vehicle and the local vehicle can both perform delivery and receipt of the article with the first buffer and the second buffer. | 05-10-2012 |
| 20120093620 | STOCKER - A stocker includes a main body provided with an opening; a port which is adjacent to the opening outside the main body and on which a FOUP can be placed; a plurality of rack portions arranged in one horizontal direction at each of a plurality of levels within the main body and configured such that articles moved by an internal movement apparatus can be put in place; a movable rack portion including a first buffer and a second buffer which are linked to each other; a shift mechanism that can be shifted between a first position where the first buffer is adjacent to the opening and a second position where the second buffer is adjacent to the opening; and a conveyor capable of moving the FOUP, via the opening, between the port and the first buffer or the second buffer positioned at a position adjacent to the opening. | 04-19-2012 |
| 20120000875 | GRIPPER DEVICE FOR TRANSPORT VEHICLE, TRANSPORT VEHICLE AND OVERHEAD HOIST TRANSPORT VEHICLE - A gripper device for a transport vehicle includes a base plate, a guide rail provided on an upper surface of the base plate, a pair of guide blocks arranged to be movable in a substantially horizontal direction toward and away from each other along the guide rail, and a pair of gripping parts. Each of the gripping parts includes a horizontal portion fixed to an upper surface of one of the guide blocks and arranged to extend substantially parallel to the upper surface of the base plate, a vertical portion arranged to extend downward from the horizontal portion to a position lower than that of the base plate, and a claw section provided on a lower end of the vertical portion and arranged to grip an object. | 01-05-2012 |
| 20100204826 | TRANSFER APPARATUS - A transfer system includes: a first shelf blocking an original transfer path from a transfer position at which the transporting vehicle transfers the transported object to the port and which transfers the transported object with the transporting vehicle; a second shelf that puts the transported object; a displacing device which reciprocates the transported object with respect to the first shelf and the port in a first direction, toward and away from the processing apparatus, and reciprocates the transported object at a first direction position, away in the first direction by the transported object from the first shelf and the port, in a second direction crossing the first direction; and a communicating device receiving a first system signal indicating a transfer request from the transporting vehicle, which transmits a second system signal indicating a transfer permission to the transporting vehicle, which transmits the first system signal to the processing apparatus. | 08-12-2010 |
| 20100202861 | TRANSFER SYSTEM - A transfer system includes: a first shelf disposed to block an original transfer path from a transfer position at which the transporting vehicle transfers the transported object to the port and can transfer the transported object with the transporting vehicle; a second shelf which puts the transported object; a displacing device can reciprocate the transported object with respect to the first shelf and the port in a first direction, toward and away from the processing apparatus, and which can reciprocate the transported object at first direction position, which is away in the first direction by the transported object from the first shelf and the port, in a second direction crossing the first direction; and a communicating device which receives a transfer request from the transporting vehicle, which can transmit a transfer permission to the transporting vehicle. | 08-12-2010 |
| 20100143084 | TRANSPORTING CARRIER - A transporting carrier for transporting a transported object and for transferring it to a bringing-in/bringing-out part, which projects from a station and which brings in or out the transported object to or from the station or for transferring the transported object from the bringing-in/bringing-out part, the transporting carrier comprising: a main body part which has loading and accommodating parts and a lateral opening, the loading part being a space to load the transported object, the accommodating part being located under the loading part, the accommodating part being a space to accommodate the bringing-in/bringing-out part such that the bringing-in/bringing-out part is at least partially surrounded from lateral sides; a traveling device on the main body part; and a transferring device above the loading part of the main body part, for transferring the transported object between the loading part and the bringing-in/bringing-out part, with the bringing-in/bringing-out part in the accommodating part. | 06-10-2010 |
| 20100117391 | TRANSPORTING APPARATUS - A transporting apparatus is provided with a main body part which defines an inner space and an opening in which the inner space is open to an external space and which can accommodate a load from the external space to the inner space through the opening; a holding device which is disposed at a position facing or in contact with the inner space of the main body part and which can hold the accommodated load within the inner space; and one or a plurality of grips which are disposed at positions facing or in contact with the external space of the main body part and which can be grabbed from the external space side. | 05-13-2010 |
