no. 1 Embodiment

[0090] Embodiments of the article conveyance facility of the present invention will be described below based on the drawings.

[0091] Such as figure 1 and figure 2 As shown, the article handling equipment is provided with a walking track 2 on the ceiling that passes through a plurality of article processing units 1 to form a walking path S, and along the walking path S, a plurality of ceiling-carrying mobile vehicles 3 ( equivalent to a mobile body). The running path S of the mobile vehicle 3 has a circular main path 4 connecting a straight portion and a curved portion, and a secondary path 5 that branches off from the straight portion of the main path 4 and merges with the straight portion of the main path 4. The main path 4 and the sub-path 5 pass through the article processing unit 1 respectively. In this article transport facility, a container for accommodating a semiconductor substrate is used as an article 6 , and the article 6 is conveyed between a plurality of art...

no. 2 Embodiment

[0136] The difference between the second embodiment and the first embodiment lies in the location where the communication relay device 26 is installed, and the other structures are the same as those of the first embodiment, so only the differences will be described.

[0137] Example 2 Figure 8 As shown, the first merging path 27 , the second merging path 28 , and the post-merging path 29 are each divided into a plurality of divided path portions 41 . In addition, the communication relay devices 26 are provided in each of the divided path sections 41 .

[0138] The relay device body 33 on the communication relay device 26 can freely communicate with the management unit 24 by associating the mobile body information with the segmentation identification information (such as the segment number of the segmented path part), and the mobile body information is passed through Obtained by communication between the antenna unit 30 and the mobile vehicle-side communication device 25, the...

Abstract

Provided are goods transport facilities capable of making mobile bodies join together at a merging section and travel while preventing the mobile bodies from colliding with each other. A first joining path (27), a second joining path (28), and an after-merged path (29) are each provided with an individual communication relay device (26). The communication relay device (26) comprises an antenna unit (30) and a relay device main body (33). The antenna unit (30) is configured with a sheet antenna. The relay device main body (33) can freely communicate with a management means (24) by associating mobile body information with identifying information, the mobile body information being obtained by communicating with a communication device (25) on the mobile body side by use of the antenna unit (30), the identifying information indicating on which of the paths the antenna unit (30) is disposed that has obtained the mobile body information. Based on the mobile body information and the identifying information received from the relay device main body (33), the management means (24) determines on which of the paths a mobile body (3) is present and manages the travels of a plurality of the mobile bodies (3).

Description

technical field [0001] The present invention relates to article conveyance equipment, which is provided with: a traveling path including at least a first path and a second path, a plurality of moving bodies for conveying articles traveling along the traveling path, and A communication relay device for performing wireless communication between the mobile side communication devices respectively installed on the mobile body side, and a management unit, the management unit is located at the junction formed by the merging of the first path and the second path. manage the operation of the plurality of mobile bodies, and transmit operation instruction information to each of the plurality of mobile bodies through wireless communication between the communication relay device and the mobile body side communication device , a walking control unit is provided on each of the plurality of mobile bodies, to control the walking of the mobile body based on the operation instruction information...
