Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray tilting angle holding mechanism used for adjusting a tilting angle of a tray used for transporting and taking out articles.

[0002]

[Prior art and its problems]

 In a tilt tray type sorting machine or the like used for transporting and sorting articles (luggage), a tray for placing and transporting articles is used. FIG. 5 shows a state in which the article A is placed on the upper part of the central portion of such a tray 2. The article A is placed on the tray 2 and then transported to a predetermined position together with the tray 2. Then, at a predetermined product take-out position, as shown in FIG. 6, the tray 2 is tilted (inclined) so that one end portion 2a thereof is downward and the other end portion 2b thereof is upward, and the article A is attached to the tray 2 It slides up and moves downward, and is guided to a chute S provided below the tray 2.

Although not shown in FIGS. 5 and 6, the lower portion for holding the tray is provided with the tilting lever portion for tilting the tray as described above, and An impact absorbing part made of rubber or the like is provided to absorb vibration when an article is placed on the tray. When the article A is a heavy object due to the rubber of the shock absorbing portion or the clearance between the wheel and the rail, the tray 2 sinks when the tray 2 is tilted as shown in FIG. A step d1 is formed between the tip of the chute S and the tip of the chute S, and the article A may fall or may not be normally shot. Further, when the article A is a lightweight article, the tray 2 rebounds to cause a step d2 as shown in FIG. 8, which may cause the article A to fall (jump).

Further, as a result of the movement of the article from the tray to the chute not being smooth as described above, the article A may be rotated (yawed) as shown in FIG. As shown in, there were cases where rotation (rolling) occurred. The present invention has been made in view of the above circumstances, and an object thereof is to provide a tray tilting angle holding mechanism capable of stably transferring an article to a chute regardless of the weight of the article. .

[0005]

[Means for Solving the Problems]

 The present invention relates to a tray tilting angle holding mechanism including a shock absorbing portion that absorbs vibration when an article is placed on a tray and a tilting lever portion that tilts the tray. A holding guide for contacting the tilted tray is provided below one end of the tray in the roll position. The holding guide may be adjustable in vertical position.

[0006]

[Action]

 In the tray tilt angle holding mechanism according to the above configuration, when the tray is tilted, one end of the tray is locked by the holding guide to hold the tilt angle. Therefore, the tray does not sink even when the article is heavy, and the tray does not rebound even when the article is lightweight.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing a tray tilting angle holding mechanism according to an embodiment of the present invention. In the figure, reference numeral 2 is a tray, and a tilting angle holding mechanism 4 and a carrying mechanism 6 for carrying the tilting angle holding mechanism 4 along rails 8 and 10 are provided below the tray.

The tilting lever mechanism 4 has a supporting portion 12 for supporting the tray 2, and a vibration-proof rubber 14 (corresponding to a shock absorbing portion) is provided below the supporting portion 12 so that the tray 2 is supported. It is designed to be able to absorb the vibration when an item is placed on the. Further, tilting arms 16 and 18 (corresponding to tilting lever portions) are provided below the anti-vibration rubber 14, and by rotating these tilting arms 16 and 18 in one direction from the outside by hitting or the like, The support portion 12 can be tilted through the contact members 20 and 22 connected to the tilting arms 16 and 18, respectively. The configurations of the shock absorbing portion and the tilting lever portion are not limited to those described above, and may be any as long as they can absorb vibrations and tilt the tray 2 by a predetermined angle. .

In this embodiment, the holding guide 24 is provided below the one end 2a of the tray 2 in the tilted position. The holding guide 24 is supported by a supporting member 30 fixed to a frame 26 and a supporting beam 28. A joint portion 32 is provided in the middle portion of the support member 30 so that the support member 30 can be expanded and contracted by the joint portion 32, whereby the vertical position of the holding guide 24 can also be adjusted. ing. A thick portion 2b is formed in the lower portion of the tray 2 in contact with the holding guide 24 to prevent the tray 2 from being worn and reinforced. In the tray tilting lever mechanism described above, when the tray 2 is tilted by the rotation of the tilting arms 16 and 18 due to an external impact or the like, as shown in FIG. 2, the tray 2 moves below its one end 2a. It is locked by the holding guide 24 and stops at an accurate tilt angle, and the tilt angle is maintained.

Therefore, the tray does not sink even when the article is a heavy article, and the tray does not rebound even when the article is a lightweight article. Therefore, regardless of the weight of the article, the article can be stably transferred to the chute, the article can be prevented from falling when transferring, and the rotation of the article after transferring the chute can be effectively prevented. be able to. Further, by adjusting the vertical position of the holding guide 24, the position at which the one end 2a of the tray 2 is locked can be adjusted, and the tilt angle of the tray 2 can be set arbitrarily.

[0011]

[Effect of device]

 As described above, in the tray tilting angle holding mechanism according to the present invention, since the holding guide for contacting the tilted tray is provided below one end of the tray at the tilting position of the tray, Items can be stably transferred to the chute regardless of weight, and it is possible to prevent the items from falling during transfer, and to effectively prevent the items from rotating or vibrating after transferring the chute. You can In addition, when the holding guide can be adjusted in the vertical position, there is an effect that the tilt angle of the tray can be arbitrarily set.
