Deformed example 1

[0074] In the above-described embodiment, the case where the shielding plate 340 covers the entire movement path of the first movable element 250 from above has been exemplified. However, the shielding plate 340A is only required to cover at least a region where the first stationary element 320 is not provided within the movement path of the first movable element 250 from above.

[0075] Hereinafter, Modification 1 will be described in detail. In addition, in the following description, the same code|symbol is attached|subjected to the same part as the above-mentioned embodiment, and the description may be abbreviate|omitted.

[0076] Figure 5 It is a top view schematically showing a schematic configuration of a ground-side facility 300A according to Modification 1. FIG. exist Figure 5 In , a pair of running rails 310 is shown dotted hatching.

[0077] Such as Figure 5 As shown, the ground-side facility 300A according to Modification 1 includes a shielding plate 340A. ...

Deformed example 2、3

[0082] In the above-mentioned embodiment, the case where the first fixing tool 320 is arranged so that the opening 321 faces the positive side in the Y-axis direction has been exemplified. However, the orientation of the opening 321 may be any orientation as long as the inside of the first fixing tool 320 cannot be seen from the opening 321 in a plan view of the first fixing tool 320 .

[0083] Figure 6 It is a cross-sectional view of the article conveyance device according to Modification 2 cut along the vehicle width direction of the conveyance trolley. Such as Figure 6 As shown, in Modification 2, the first fixing member 320a is disposed such that the opening 321a faces obliquely downward. Specifically, the opening 321 a faces a direction inclined at 45 degrees to the negative side of the Z-axis direction with respect to the Y-axis direction. Even in this case, the inside of the first fixing tool 320a cannot be seen from the opening 321a when the first fixing tool 320a...

Abstract

An article conveyance device (100) includes a trolley (200) traveling along a predetermined traveling path (R), and ground-side equipment (300) having a pair of traveling rails (310) defining the traveling path. The trolley is equipped with a first movable member (250) that operates magnetically to drive a transfer mechanism (230), and a drive transmission mechanism (240) that supports the first movable member and transmits a driving force from the first movable member to A movable part is transferred to the transfer mechanism. The ground-side equipment includes a first fixture (320) that applies a magnetic action to a first movable element of the trolley to move the first movable element. The first fixture has an opening (321) through which the drive transmission mechanism of the trolley passes, and is arranged at a position where the interior of the first fixture cannot be seen from the opening when the first fixture is viewed from above.

Description

technical field [0001] The present invention relates to an article conveying device for conveying articles using a ground-driven linear motor. Background technique [0002] Conventionally, there is known an article conveyance device in which a conveyance trolley having a transfer conveyor travels on a traveling path by thrust generated by a linear motor (for example, refer to Patent Document 1). A mover for driving the transfer conveyor is mounted on the transfer trolley, and a stator for imparting a magnetic action to the mover of the transfer table is provided at a predetermined position on the traveling road. In other words, if the transport trolley stops or decelerates to a specified position on the traveling road, the movable part on the transporting trolley side and the fixed part on the traveling road side constitute a motor, and the transfer conveyor is driven by the magnetic action of the motor. . [0003] Patent Document 1: Japanese Publication No. 7-21452 [00...
