DAIFUKU CO., LTD.

According to a transfer system ( 1 ), in a case where a first detecting part ( 201 ) detects that an article ( 2 ) is lifted above a first height (H 1 ), a picking head ( 12 a ) is moved toward a second transfer position (P 2 ) and a first container ( 17 ) in which another article ( 2 ) is housed is transported to a first transfer position (P 1 ).

Achieved is a conveyance device including a mechanism which reduces a gap to be generated between each of carriages coupled to each other and a path along which the carriages pass. A conveyance device ( 1 ) to be conveyed along a conveyance path ( 6 ) includes: a plurality of main carriages ( 2 ); and a plurality of sub-carriages ( 3 ) that are located between the main carriages and that are connected so as to be movable with respect to the main carriages. The main carriages and the sub-carriages are alternately provided. The sub-carriages each include a step ( 7 ) configured to be drawn therefrom in a direction perpendicular to a movement direction of a conveyance path and in an area in which the conveyance path bends.

A verification system includes a reference field intensity setter, a field intensity obtainer, and a verification processor. The reference field intensity setter sets a reference radio field intensity at each of a plurality of observation sites in a target area. The field intensity obtainer obtains observation-site field-intensity information indicating at least one of a predictive value of a radio field intensity calculated for each observation site or a measurement value of the radio field intensity measured for each observation site. The verification processor performs a verification process based on the observation-site field-intensity information. The verification process includes a removable-access-point extraction process for extracting a removable wireless access point that is removable while satisfying a field intensity condition. The field intensity condition is satisfied when the radio field intensity at all the plurality of observation sites is higher than or equal to the reference radio field intensity.

An article transport facility includes a control system. The control system executes: route extraction processing for extracting a plurality of candidate routes by referring to map information; cost correction amount deriving processing for deriving a cost correction amount for each of the plurality of candidate routes based on a combination of shapes of a plurality of links included in the candidate route; and route selection processing for selecting a candidate route having the smallest route cost out of the plurality of candidate routes, as a movement route of a transport vehicle, by calculating a route cost of each candidate route based on a sum of standard costs of all links included in the candidate route R and the cost correction amount determined for that candidate route in the cost correction amount deriving processing.

In a transport facility, a control system performs traffic control in permitting a transport vehicle at a target stop-point among stop-points or at a point upstream from the target stop-point to travel through a merging area. The control includes causing an occupancy point to enter an occupied state in which the occupancy point is occupied by a permitted transport vehicle, prohibiting, during the occupancy point being in the occupied state, transport vehicles other than the permitted transport vehicle from traveling at least from the target stop-point to the occupancy point, and canceling the occupied state after the permitted transport vehicle passes the occupancy point. During the control, the control system permits, when transport vehicles traveling to the merging area include same-path transport vehicles having a same combination of the occupancy point and a stop-point to travel through, the same-path transport vehicles to sequentially travel through the merging area.

Reference points (P) included in a reference point group (PG) are arranged to define, as a travel path, a first path (R 1 ), a second path (R 2 ), a third path (R 3 ), a fourth path (R 4 ), a fifth path (R 5 ), and a sixth path (R 6 ). The first path (R 1 ) and the second path (R 2 ) extend toward a first side (X 1 ) in a first direction. The third path (R 3 ) and the fourth path (R 4 ) extend toward a second side (X 2 ) in the first direction. The fifth path (R 5 ) extends toward a first side (Y 1 ) in a second direction. The sixth path (R 6 ) extends toward a second side (Y 2 ) in the second direction. Four paths including the second path (R 2 ), the third path (R 3 ), the fifth path (R 5 ), and the sixth path (R 6 ) define, on a travel surface ( 11 ), an area (T) including a standby area (W) in which a transport vehicle ( 1 ) waits.

An article transport facility includes a travelable path divided into multiple areas. A controller performs, in response to the areas including a high-density area having a higher density of movable bodies than another area among the areas, distribution control to change a destination of at least one movable body to an escape destination to reduce a density of movable bodies in the high-density area. In the distribution control, the controller sets, in response to target movable bodies in the high-density area including a transporting movable body transporting an article toward a transfer destination outside the high-density area to transfer the article, the escape destination of the transporting movable body inside an area, among the areas, closer to the transfer destination than the high-density area.

Correcting a deviation of the transfer position of an article is made possible. A control section includes: a position information acquiring section for acquiring, from an image taken by an image taking section, position information and a deviation of an identification code from a reference position; and an action control section for controlling the action of a transport device so as to correct the deviation of the transfer position of the article in accordance with the position information and the deviation of the identification code from the reference position.

To enable an operator to recognize arrival of a sorting target article, even while the operator is away from an operation area. A first control section ( 12 ) of a control device ( 1 ) determines a sorting destination on the basis of identification information that has been read by a reading device ( 3 ), and causes a first wireless communication section ( 11 ) to transmit information on reception of an article to a mobile terminal ( 2 ) that is associated with the determined sorting destination. A second control section ( 22 ) of the mobile terminal ( 2 ) causes a notification section ( 24, 26, 27 ) to notify an arrival timing at which the article is to arrive at the sorting destination, on the basis of the information on the reception of the article which has been received by a second wireless communication section ( 21 ).

Work for installation of a feed line is efficiently conducted. An installation tool installs a feed line in a feed line holder, the feed line holder accompanying any of rails for allowing a carrier to travel thereon and holding the feed line, the feed line feeding electric power to the carrier in a non-contact manner. The installation tool includes: a main body part configured to be capable of moving along the rails; and a pressing part configured to move together with the main body part along the rails and continuously press the feed line into a holding part of the feed line holder as the main body part is moved, the holding part being partially open.
