[0028] In combination with the drawings Figures 1-9 , the lifting machine based on the multi-path flexible conveying line comprises: a rack assembly 1, a hanging basket lifting assembly 2 and a bottom layer conveying line assembly 3 arranged on the rack assembly 1, and a conveying line formed by the staggered layered design. The power assembly 5 drives the transmission chain 6 and the driving chain 7 through the sprocket arranged on the rack assembly 1 and in combination with the design of the driving shaft assembly, so as to continuously lift or lower the hanging basket lifting assembly 2 between the bottom layer and the top layer, and make the workpiece switch between different conveying routes without stopping. Therefore, the new lifting machine based on the innovative application of the flexible conveying line enables the intelligent upgrading and development of enterprises and the flexible and efficient production of enterprises.

[0029] The lifting machine based on the multi-path flexible conveying line comprises:

[0030] The rack assembly 1 is a component body of a metal frame, which supports the mutual conveying of workpieces between the latitudes of different conveying lines in the three-dimensional space. In different intelligent factories, the rack assembly 1 can be a two-layer or multi-layer structure design, which is suitable for two-layer or multi-layer conveying lines and serves the conveying routes of different workpieces.

[0031] Further, the rack assembly 1 comprises a three-dimensional rack 11, a guide support 12 installed at the bottom layer, and a transmission sprocket 13 arranged at the top and bottom of the three-dimensional rack 11, and a transition sprocket 14 arranged at the bottom of the three-dimensional rack 11. Specifically, the three-dimensional rack 11 is a three-dimensional metal frame structure, and the guide support 12 extends outward at the bottom layer.

[0032] In the present embodiment, the transmission sprocket 13 is arranged at the top and bottom of the three-dimensional rack 11, and the transmission sprocket 13 is divided into three groups, two groups are arranged at the top and bottom of the same side of the three-dimensional rack 11, and the other group is arranged at the bottom of the three-dimensional rack 11. Specifically, the number of each group of transmission sprocket 13 is two. The transition sprocket 14 arranged at the bottom of the three-dimensional rack 11 is arranged at the bottom of the three-dimensional rack 11 at the same side as the single group of transmission sprocket 14, and the transition sprocket 14 is a group, and the number of each group of transition sprocket 14 is two.

[0033] The basket lifting assembly 2 is a metal frame body, which is used to switch the running path of the conveying line and provides more routes for the conveying of workpieces.

[0034] Further, the basket lifting assembly 2 comprises a lifting frame 21, and a basket conveying unit 22 connected to the lifting frame 21; the basket conveying unit 22 comprises a basket frame 221 and a basket roller 222 arranged on the basket frame 221. Specifically, the lifting frame 21 is an inverted square frame, and the four ends extend inward to form mounting columns. The basket conveying unit 22 and the lifting frame 21 form a "basket" that can lift workpieces.

[0035] The bottom layer conveying line assembly 3 is a matching assembly matched with the conveying line at the bottom layer, and is arranged on the guide support 12. When the workpiece is transported by the bottom layer conveying line, it will enter the liftable conveying area.

[0036] Further, the bottom layer conveying line assembly 3 comprises a conveying line frame 31, and a transmission roller 32 and an adaptive roller 33 arranged on the conveying line frame 31; the transmission roller 32 is arranged on the outside of the three-dimensional rack 11, and the adaptive roller 33 is arranged in a staggered manner in the vertical direction with the basket roller 222. Specifically, when the basket lifting assembly 2 is lowered to the bottom layer conveying line assembly 3, the adaptive roller 33 of the bottom layer conveying line assembly 3 is matched with the basket roller 222 of the basket lifting assembly 2, and the staggered arrangement forms an integrated conveying line. If a workpiece is transported by the bottom layer conveying line (not shown in the figure) to the bottom layer conveying line assembly 3, it enters the conveying area formed by the adaptive roller 33 and the basket roller 222, and when the workpiece needs to be lifted, the basket lifting assembly 2 can be directly lifted. Since the adaptive roller 33 is still in the original conveying line frame 31, the subsequent conveying process of the workpiece is not affected, and the subsequent conveying of the workpiece does not need to wait for the basket lifting assembly 2 to lift the previous workpiece or to be processed by manual operation. Therefore, the efficiency of the continuous operation of the workpiece is ensured.

[0037] The driving shaft assembly 4 is arranged at the top of the three-dimensional frame 11, and includes a rotating shaft 41 and a driving sprocket 42 arranged at two ends of the rotating shaft 41.

[0040] The driving chain 7 includes a first driving chain 71 and a second driving chain 72. The first driving chain 71 passes through the driving sprocket 42 and is connected to the top of the lifting frame 21 and the power assembly 5, respectively.

Specifically, the power output end of the power assembly 5 is connected to one end of the first driving chain 71 and the second driving chain 72, which can ensure the stability of the lifting frame 21 during lifting and avoid shaking.

[0041] The power assembly 5 drives the first driving chain 71 to move, and the second driving chain 72 moves accordingly, driving one end of the lifting frame 21 to rise or fall. The lifting or falling of the lifting frame 21 drives the other end of the lifting frame 21 to rise or fall synchronously through the transmission chain 6.

[0042] Therefore, the lifting machine based on the multi-path flexible conveying line adopts the ingenious arrangement of the adaptive roller 33 and the basket roller 222 in the vertical direction, which ensures the continuity of the workpiece during conveying and prevents the workpiece from being paused during upward lifting. The first driving chain 71 and the second driving chain 72 drive the lifting frame 21 in a "mutually exclusive" manner, which makes the lifting frame 21 run stably and prevents it from shaking. In combination with the frame assembly 1, the bottom conveying line assembly 3, the driving shaft assembly 4, the power assembly 5, the transmission chain 6 and other components, a flexible conveying line is built to plan different conveying paths for the workpiece, provide an efficient lifting machine to adapt to the flexible conveying line, and make the production process of the intelligent factory more smooth and efficient.

Specifically, the power mechanism 51 is a cylinder, and the power sprocket 53 is a movable pulley.

[0045] In other embodiments, the multi-path flexible conveying line-based elevator further comprises a counterweight guide rail 81 arranged on the stereoscopic frame 11; the counterweight 8 is slidably connected with the counterweight guide rail 81. In addition, the multi-path flexible conveying line-based elevator further comprises a support guide rail 16 arranged on both sides of the stereoscopic frame 11; the lifting frame 21 is slidably connected with the support guide rail 16.

[0046] Further, the counterweight guide rail 81 and the support guide rail 16 are T-shaped.

The side surface of the lifting frame 21 is provided with a guide shoe, and the lifting frame 21 is slidably connected with the T-shaped support guide rail 16 through the guide shoe.

[0047] In an embodiment, the layout of the sprocket and the chain of the multi-path flexible conveying line-based elevator is as follows: the transmission sprocket is three groups, two of which are arranged at the top and the bottom of the same side of the stereoscopic frame 11, and the other group is arranged at the bottom of the stereoscopic frame 11 and on the same side of the drive shaft assembly 4; the transition sprocket 14 is one group, which is arranged at the bottom of the stereoscopic frame 11 and on the same side of the drive shaft assembly 4; the number of each group of transmission sprocket 13, transition sprocket 14, and the corresponding transmission chain 6 and drive chain 7 is two; the power assembly 5 is on the same side of the drive shaft assembly 4.
