the two square rods 20 drive the transport rods 2 to move, the transport rods 2 drive the transport push plates 18 mounted on the transport rods to move, and the transport push plates 18 move to push goods on the frame body 1 to move forwards; after the four sliding mechanisms 22 move to the foremost ends of the corresponding first sliding ways 24, the driving rod 21 drives the transportation rod 2 to move backwards, the transportation rod 2 moves to drive the transportation push plate 18 to move, meanwhile, the transportation rod 2 moves to drive the two square rods 20 arranged on the transportation push plate to move, and the two square rods 20 move to drive the four sliding mechanisms 22 arranged on the transportation push plate to slide backwards in the corresponding guide rails 4; at this time, the transport push plate 18 arranged on the transport rod 2 is directly separated from the goods, and the friction in the up-and-down direction can not occur; as shown in a of fig. 18, after the four sliding mechanisms 22 slide from the first slideway 24 on the corresponding guide rail 4 to the junction of the first slideway 24 and the second slideway 26, as shown in b of fig. 18, under the action of gravity and the corresponding trigger ramps 25 in the four guide rails 4, the four sliding mechanisms 22 slide into the corresponding fifth slide ways 29, and slides along the fifth slideway 29 towards the corresponding fourth slideway 28, as shown at c in figure 18, since the cross-section of the fifth ramp 29 tapers from the end connected to the first ramp 24 to the end connected to the fourth ramp 28, during the movement of the four slide mechanisms 22, the four mounting cases 31 in the four slide mechanisms 22 are pressed, and the four mounting cases 31 move toward the end where the connecting rod 33 is mounted, the four mounting cases 31 move to press the corresponding return springs 32 so that the return springs 32 are compressed; during the process that the four sliding mechanisms 22 slide in the corresponding fifth slide ways 29, the upper end of the transport push plate 18 mounted on the transport rod 2 gradually moves to the lower side of the upper end surface of the rack body 1; as shown in a in fig. 19, after the four sliding mechanisms 22 move to completely slide out of the corresponding fifth slide ways 29 into the corresponding fourth slide ways 28, the four sliding mechanisms 22 will continue to slide along the corresponding fourth slide ways 28, as shown in b in fig. 19, after the four sliding mechanisms 22 move to completely slide out of the corresponding fourth slide ways 28 into the corresponding third slide ways 27, the four mounting shells 31 in the four sliding mechanisms 22 will move to reset under the action of the four reset springs 32, so that one ends of the four mounting shells 31 away from the connecting rods 33 are in contact with the inner end surfaces of the corresponding third slide ways 27; the four sliding mechanisms 22 slide to the initial sliding position and then continue to slide, thereby continuously pushing the goods on the shelf body 1. The change of the section ensures that the sliding mechanism can only slide in the track in one direction.
In summary, the following steps:
compared with four link rod transportation mechanisms shown in fig. 5.2-1, 5.2-2, 5.2-3 and 5.2-5 from 100 pages to 101 pages in section 5.2 of a mechanical design practical mechanism and device atlas, the transportation mechanism has vertical abrasion between the transportation member and goods after the transportation member moves to the upper side, and the goods table body is damaged due to abrasion; the transport device of the present invention is designed in contrast to the link transport mechanism shown in fig. 5.2-4 on page 101 in section 5.2 of the mechanical design utility and device album, although this transport mechanism achieves no wear in the vertical direction after the transport member has moved to the upper side; however, the transportation mechanism needs to finally realize the law of transportation swing through a precisely designed cam and link mechanism; when the track is adjusted, the cam and the connecting rod need to be redesigned, which brings inconvenience to the applicability of the mechanism; the conveying mechanism designed by the invention realizes the conveying swing rule through the four guide rails 4 and the connecting rods; when the track is adjusted, the four guide rails 4 are directly taken down, and other suitable guide rails 4 with the same total length are replaced, so that the use is convenient, and the applicability is better.
