[0063] The first specific embodiment of the present invention provides a rail alignment mechanism, which is used to connect the transition rail and the running rail in the three-dimensional storage system, so as to change rails for the picking device. In the three-dimensional storage system, a plurality of running tracks are arranged in parallel, and one end of each running track has a preset distance greater than zero from the transition track.
[0064] see Figure 2 to Figure 6 , figure 2 A schematic structural view of the rail alignment mechanism provided for the first specific embodiment of the present invention; image 3 Schematic diagram of the structure when the free end of the docking rail in the rail alignment mechanism provided by the first specific embodiment of the present invention is in a retracted state; Figure 4 Schematic diagram of the structure when the free end of the docking rail in the rail alignment mechanism provided by the first specific embodiment ...
no. 2 Embodiment
[0091] The working process of the track changing device is basically: after the track changing device runs to one end of the running track where the pick-up device to be changed is located, the docking track in the track changing device is aligned with the end of the running track to compensate for the gap between the track and the running track. The gap between a (see figure 2 ), so that the picking device can be smoothly transferred to the rail changing device.
[0092] However, in actual construction, the running track is generally composed of two parallel monorails (see figure 1 In the first running monorail 31 and the second running monorail 32), there will be installation errors at the ends of the two monorails, which will easily lead to deviation problems when the docking mechanism in the pick-up device docks with the running track, that is: the docking track and a When the side monorail is seamlessly docked in place, the butt joint gap with the other side monorail is...
no. 3 Embodiment
[0101] The third specific embodiment of the present invention provides a three-dimensional storage system. The three-dimensional storage system includes a picking device, a rail changing device, a transition rail and a plurality of running rails arranged in parallel. in:
[0102] The pick-up device can move back and forth on each running track;
[0103] There is a preset distance greater than zero between one end of each running track and the transition track;
[0104] The rail changing device can reciprocate on the transition track, and the rail changing device is the rail changing device provided in the second embodiment of the present invention.
[0105] After the movable section 5 of the docking track in the rail changing device moves away from the fixed section 4 of the docking track, it can be docked with a running track, and the pick-up device can be moved from the running track to the fixed section 4 of the docking track of the changing rail device;
[0106] After th...
