no. 1 Embodiment approach 〕

[0024] A first embodiment of the article conveyance device will be described based on the drawings. Such as figure 1 As shown, the article conveying device of this embodiment includes a stacking crane 1 that is guided by a lower rail R1 and an upper rail R2. The lower rail R1 is provided on the ground and extends linearly. They are arranged in parallel and extend linearly.

[0025] The stacking crane 1 includes a traveling body 4, a pair of rods 5 (first rod 5A, second rod 5B), an upper frame 6, and an elevating body 7. The traveling body 4 supports a traveling wheel 3 rolling on a lower rail R1. A pair of rods 5 (the first rod 5A, the second rod 5B) are in the traveling direction ( figure 1 in the direction indicated by X. Hereinafter it is referred to as the traveling direction X. ) to leave, being moved along the up and down direction ( figure 1 in the direction indicated by Z. Hereinafter, it will be referred to as an up-down direction Z. ) is erected, the aforem...

no. 2 Embodiment approach 〕

[0054] based on Figure 6 and Figure 7 A second embodiment of the article conveyance device will be described. This embodiment differs from the first embodiment described above in that the rotation resistance applying device 40 is provided on the brake unit 12 . Hereinafter, the article conveying device of this embodiment will be described focusing on differences from the first embodiment. About the point which is not specifically described clearly, it is the same as that of 1st Embodiment, and the same code|symbol is attached|subjected, and detailed description is abbreviate|omitted.

[0055] Such as Figure 6 As shown, the brake unit 12 of the present embodiment is configured such that, with respect to the brake unit 12 of the above-mentioned first embodiment (refer to Figure 4 ) additional rotation resistance applying device 40 for applying rotation resistance. The rotation resistance applying device 40 is provided on the rotation shaft 30 of at least one of the firs...

Abstract

This article transport apparatus comprises: a mast which is erected on a traveling body; an upper frame (6) which is connected to the upper end of the mast; and an upper rail (R2) which guides the movement of the upper frame (6). Separately of guide rollers arranged on the left and right sides of the upper rail (R2), a first roller (18A) and a second roller (18B) which are rotatable about upper and lower axes (P1, P2) are arranged on opposite sides of the upper rail (R2). A first supporting member (19) for supporting the first roller (18A) is mounted while being urged in a direction to press the first roller (18A) against the upper rail (R2) by means of a first biasing body (22). A second supporting member (20) for supporting the second roller (18B) is mounted while being urged in a direction to press the second roller (18B) against the upper rail (R2) by means of a second biasing body (22).

Description

technical field [0001] The present invention relates to an article conveyance device. The article conveyance device includes a lower rail, a traveling body, a rod, an upper frame, an upper rail, and a lifting body. The lower rail is installed on the ground. The rod is erected on the traveling body, the upper frame is connected to the upper end of the rod, the upper rail extends along the traveling direction of the traveling body, and guides the movement of the upper frame, and the lifting body is equipped with a transfer device for transferring articles, and is lifted and lowered along the rod The upper frame is equipped with at least two guide rollers that are rotatable around the vertical axis and are separately disposed on both sides of the upper rail and guided by the upper rail when viewed in the vertical direction, in a fixed position relative to the upper frame. Background technique [0002] As an example of such an article conveyance device, in order to shorten the c...
