[0027] Embodiment 1

[0028] The utility model discloses a material handling system, and will be described below in conjunction with the drawings, such as the drawings Figure 1 As shown in the drawings, the material handling system comprises a track structure 100 and a material transport vehicle 200 moving along the track structure 100, and the track structure 100 comprises a lower track 110 suspended under the ceiling, for example, and the specific layout and form of the lower track 110 can be designed according to the needs, which is not limited here. The lower track 110 is provided with a temporary stop point 112 matched with each processing equipment and storage equipment, etc. for the material transport vehicle 200 to temporarily stop for picking, unloading and other operations. The material transport vehicle 200 is, for example, a known overhead crane, and its specific structure is known technology, which is not described here.

[0029] Unlike the prior art, as shown in the drawings Figure 1 The track structure 100 further comprises at least one upper track 120 higher than the lower track 110, and the two ends of the upper track 120 are connected with the lower track 110 through a connecting mechanism 130 to enable the material transport vehicle 200 to move between the lower track 110 and the upper track 120.

[0030] The height difference between the upper rail 120 and the lower rail 110 ensures that when the material transport vehicle 200 is running on the upper rail 120, the material transport vehicle 200 and the materials it grabs will not interfere with the lower rail 110 and the material transport vehicle 200 on the lower rail 110. The specific installation height of the upper rail 120 can be designed as needed and is not limited here.

[0031] No temporary stopping point 112 is set at the upper track 120, and the speed of the material transport vehicle 200 on the upper track 120 can be higher than the speed of the material transport vehicle 200 on the lower track 110. Thus, when there are no other material transport vehicles 200 on the upper track 120, a material transport vehicle 200 can pass through the upper track 120 faster.

[0032] The specific location and number of the upper rails 120 can be determined according to actual needs, for example, as shown in the attached figure. Figure 1 As shown, the lower track 110 includes multiple local segments 111, and temporary stopping points 112 are set at one or more local segments 111. At this time, the upper track 120 can match each local segment 111 with a temporary stopping point 112.

[0033] The upper track 120 and the lower track 110 can be connected by different connecting mechanisms 130. In one embodiment, as shown in the attached figure... Figure 1 As shown, some local segments 111 of the lower track 110 are spaced apart. The two ends of the upper track 120 and the two ends of its corresponding local segments 111 are aligned and flush in the height direction. Preferably, the upper track 120 and its corresponding local segments 111 are aligned in the height direction. In this case, the connecting mechanism 130 connecting the two ends of the upper track 120 and its matching local segments 111 includes at least one connecting track 131 and a connecting switching mechanism 132 that drives the connecting track 131 to move up and down.

[0034] Typically, one of the connecting tracks 131 includes two parallel, equal-height, and flush horizontal rails. To improve the safety of the material transport vehicle 200 during movement, the top surface of the horizontal rails can include a first inclined surface and a second inclined surface that are connected. The opposite ends of the first and second inclined surfaces are lower than their opposite ends. The first and second inclined surfaces are symmetrically arranged, and their inclination angle can be set to be relatively small, for example, not exceeding 5°, depending on the specific design requirements.

[0035] The connecting and switching mechanism 132 is, for example, a known scissor lift, a telescopic cylinder lift, an industrial elevator, or other feasible equipment, and is not limited here. The connecting and switching mechanism 132 drives the connecting rail 131 to selectively connect with the upper rail 120 and the partial segment 111. That is, in the first position, the connecting rail 131 connects between the two partial segments 111 of the lower rail 110, and in the second position, the connecting rail 131 connects to one end of the upper rail 120.

[0036] Under normal conditions, the connecting track 131 can be kept in the first position. When a material transport vehicle 200 needs to move from the lower track 110 to the upper track 120, the material transport vehicle 200 moves to the connecting track 131 in the first position. Then, the connecting switching mechanism 132 drives the connecting track 131 to move upward and connect with the upper track 120. At this time, the material transport vehicle 200 moves to the upper track 120 and moves to the other end of the upper track 120. When the material transport vehicle moves to the other end, the connecting track 131 of the connecting mechanism 130 connected to the other end of the upper track 120 is switched to the second position. At this time, the material transport vehicle 200 moves to the connecting track 131 at the other end. Then, the connecting track 131 at the other end moves down to the first position, and the material transport vehicle 200 returns to the lower track 110.

[0037] In the above embodiments, there may be only one connecting track 131. In another embodiment, as shown in the attached figure... Figure 2 As shown, there are two connecting tracks 131, which are set at different heights. The height difference between the two connecting tracks 131 is consistent with the height difference between the upper track 120 and the lower track 110. At the same time, the two connecting tracks 131 are driven to move up and down by the connecting switching mechanism 132. In the first position, the lower connecting track 131 is located below the lower track 110, and the upper connecting track 131 is connected between two local segments of the lower track 110. In the second position, the lower connecting track 131 is connected between two local segments of the lower track 110, and the upper connecting track 131 is connected to the upper track 120.

[0038] In this structure, under normal conditions, the two connecting tracks 131 are in the first position, where the upper connecting track 131 is connected to the lower track 110. When the material transport vehicle 200 needs to move onto the upper track 120, the material transport vehicle 200 first moves onto the upper connecting track 131. Then, the connecting switching mechanism 132 drives the two connecting tracks 131 to rise to the second position, and the material transport vehicle 200 moves from the upper connecting track 131 onto the upper track 120. At this time, the lower connecting track 131 connects the partial sections 111, allowing the material transport vehicle 200 at the lower track 110 to still pass normally. When it is determined that no material transport vehicle 200 needs to move to the corresponding partial section 111 of the upper track 120, the connecting switching mechanism 132 drives the two connecting tracks 131 back to the first position.

[0039] In another embodiment, there are also two connecting tracks 131, which are set at different heights. The difference from the above embodiment is that the two connecting tracks 131 can be driven by two independent connecting switching mechanisms 132. The specific working principle is the same as that of the above embodiment, and will not be described in detail here.

[0040] In another embodiment, as shown in the appendix Figure 3 As shown, the multiple local segments 111 of the lower track 110 are continuous. In this case, each upper track 120 is parallel to its corresponding local segment 111 and they are staggered in the height direction. Of course, this is not necessary. It is sufficient to ensure that the two ends of the upper track 120 are located on the side of the lower track 110. For example, the upper track 120 is a curved track and its two ends are located on the same side of the local segment 111, or the two ends of the upper track 120 are located on both sides of the local segment 111.

[0041] At this time, as attached Figure 3 Appendix Figure 4 As shown, the connecting mechanism 130 includes a lateral shift section 133 extending outward from the side of the lower track 110 and a ramp section 134 connected to the lateral shift section 133. The upper end of the ramp section 134 is connected to one end of the upper track 120. Thus, when the material transport vehicle 200 needs to enter a section of the upper track 120 from the lower track 110, the material transport vehicle 200 can move outward from the lower track 110 via the lateral shift section 133 of the connecting mechanism 130 connected to one end of the upper track 120, move to the ramp section 134 of the connecting mechanism 130, and move upward to enter the upper track 120. When the material transport vehicle 200 continues to move towards the other end of the upper track 120 to the connecting mechanism 130 at the other end, it moves downward along the ramp section 134 of the connecting mechanism 130 at the other end and returns to the lower track 110 via the lateral shift section 133 of the connecting mechanism 130 at the other end.

[0042] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
