Description

Technical Field

[0001] The present application relates to the technical field of body-in-white welding and final assembly, and in particular to a high-speed conveying system. Background Art

[0002] In the field of body-in-white welding and assembly technology, the conveying speed of the conveying system directly affects the production rhythm, and the roller bed trolley conveying system is one of the most widely used conveying equipment in automobile welding workshops. How to control the conveying speed has become the focus of research.

[0003] At present, a transition station is set in the roller bed trolley conveying system. The transition station is arranged between the first conveying station and the elevator station to achieve the transition between the upper conveying line and the lower conveying line. The transition station is arranged between the buffer stations of the same production line to achieve the transition of the buffer station. However, setting a transition station in the roller bed trolley conveying system will, on the one hand, lengthen the length of the entire production line and increase the floor space. On the other hand, the connection between the transition station and other structural parts will increase the conveying time, resulting in changes in the conveying speed and reducing the efficiency of the production line. Summary of the invention

[0004] Based on this, it is necessary to provide a high-speed conveying system to address the above problems. The high-speed conveying system can achieve transition without increasing the length of the production line, thereby ensuring the efficiency of the production line.

[0005] The present application provides a high-speed conveying system, comprising:

[0006] The lifting mechanism comprises a lifting bracket, a lifting assembly and a tray assembly, wherein the lifting assembly can be slidably arranged on the lifting bracket in a vertical direction, and the tray assembly is arranged on the lifting assembly;

[0010] In the above-mentioned high-speed conveying system, the trolley is transported on the conveying mechanism as the conveying station moves. When the trolley driving member of the trolley and the traction driving member of the traction mechanism are matched, the trolley transitions from the conveying mechanism to the traction mechanism and moves smoothly with the traction end of the traction mechanism. By setting the traction mechanism between the conveying station and the pallet assembly, and limiting the traction mechanism to be able to extend to the conveying station, so that the trolley can transition to the conveying station of another layer of the conveying mechanism through the traction mechanism and the lifting mechanism to continue transportation, the setting of the traction mechanism does not need to increase the length of the conveying mechanism in the conveying direction, nor will it affect the arrangement length of the lifting mechanism and the conveying mechanism, and the trolley driving member of the trolley can be matched with the traction driving member of the traction mechanism to make the trolley and the traction mechanism rigidly contact, the connection between the two will not affect the conveying speed, thereby ensuring the efficiency of the production line.

When the buffer position lifting roller beds 630 are lowered, the trolley 500 is separated from the trolley 500, and the trolley 500 falls onto the transverse moving machine 610.

[0065] When the above-mentioned high-speed conveying system 10 is working, the conveying position lifting roller bed 620 rises, and the traction mechanism 400 transfers the trolley 500 on the first conveying station 210 to the conveying position lifting roller bed 620, and then the trolley 500 descends together with the conveying position lifting roller bed 620, and the trolley 500 falls back onto the transverse moving machine 610, and rises at the cache position lifting roller bed 630, and the trolley 500 moves transversely to the cache position lifting roller bed 630 through the transverse moving machine 610, and the cache position lifting roller bed 630 supports and transports the trolley 500, and the trolley 500 descends together with the cache position lifting roller bed 630, and the trolley 500 falls back onto the transverse moving machine 610, and can continue to move transversely through the transverse moving machine 610 to realize the diversion, transverse movement, caching and transmission of the trolley 500.

[0066] The structure of the cache position lifting roller bed 630 has various forms. In a preferred embodiment, referring to FIG8, FIG9, FIG10 and FIG11, when the cache position lifting roller bed 630 rises, the cache position lifting roller bed 630 is used to receive the trolley 500, and the cache position lifting roller bed 630 is also used to drive the trolley 500 by friction to achieve the movement of the trolley 500. In one example, a cache drive 640 is installed on the cache position lifting roller bed 630, and the cache drive 640 can be a roller. The bottom surface of the trolley 500 is in friction contact with the cache drive 640, so that the trolley 500 is driven to move together by the cache drive 640. In one example, the cache drive 640 has a conveying power, and the cache drive 640 can rotate on the cache position lifting roller bed 630. In another example, the transport position lifting roller bed 620 has a plurality of third support wheels 650, which are used to support the support surface 510 of the trolley 500 during the transport of the trolley 500. The third support wheels 650 do not transmit power and are only used to provide a support function.

[0067] In order to further cache the trolley 500, in a preferred embodiment, referring to Figures 8, 9, 10 and 11, the number of the cache mechanisms 600 is multiple, and when the multiple cache mechanisms 600 are arranged between two adjacent first conveying stations 210, the adjacent cache position lifting rollers 630 of the adjacent cache mechanisms 600 transfer the trolley 500 along the conveying direction X, and the transverse movement directions of the transverse machines 610 of the adjacent cache mechanisms 600 are opposite, so that the trolley 500 transitions from the first conveying station 210 through the traction mechanism 400 to the cache mechanism 600, having The two cache position lifting rollers 630 on the transverse machine 610 can be used for diversion cache. After the trolley 500 is transported to a cache position lifting roller 630, the cache transport passing through it can be transitioned along the transport direction X to the adjacent cache position lifting roller 630 along the transport direction X. At this time, the trolley 500 can be transported to the corresponding transport position lifting roller 620 or the cache position lifting roller 630 on the other side through the transverse machine 610 where this cache position lifting roller 630 is located, so that the movement process of the trolley 500 is more complicated and can adapt to cache transitions with different needs.

[0068] The structure of the tray 131 has various forms. In a preferred embodiment, as shown in FIG. 12 and FIG. 13 , the tray 131 has a C-shaped opening 1311. The C-shaped opening 1311 of the tray 131 can be connected to the first conveying station 210. At this time, the traction mechanism 400 may not be set between the first conveying station 210 and the tray 131. The first conveying station 210 of the first conveying mechanism 200 can directly enter the lifting mechanism 100 and connect with the tray 131. The trolley 500 is directly transferred from the first conveying station 210 to the tray 131. This high-speed conveying system 10 can save the traction mechanism 400 and reduce production costs. Of course, the opening of the tray 131 is not limited to the C-shape and can also be other structural forms. It is just that the traction mechanism 400 needs to be set between the conveying mechanism and the lifting mechanism 100 in the high-speed conveying system 10 at this time, so as to realize the transfer of the trolley 500 between the conveying mechanism and the lifting mechanism 100 through the extended end of the traction mechanism 400. In one example, one end of the tray 131 is extended out of the lifting bracket 110, and a traction mechanism 400 is set on the first conveying station 210 of the first conveying mechanism 200. At this time, the traction mechanism 400 can be connected with the tray 131 without entering the lifting mechanism 100, thereby avoiding interference.

[0069] In order to further simplify the structure of the high-speed conveying system 10, in a preferred embodiment, referring to FIG. 12 and FIG. 13, the tray 131 has a C-shaped opening 1311, the traction mechanism 400 is arranged on the tray 131, and the extended end of the traction mechanism 400 can extend out of the C-shaped opening 1311 of the tray 131. When the trolley 500 on the first conveying mechanism 200 needs to transition to the lifting mechanism 100, the traction mechanism 400 moves with the tray 131 to the position where the first conveying mechanism 200 is located, and the extended end of the traction mechanism 400 extends out of the C-shaped opening 1311 of the tray 131, and the trolley 500 is lifted from the first conveying station 210 of the first conveying mechanism 200. It transitions to the traction mechanism 400, and as the traction end 410 of the traction mechanism 400 moves, it enters the pallet 131, and then the traction mechanism 400 and the trolley 500 move together with the pallet 131 to the position of the second conveying mechanism 300, the trolley 500 extends out of the C-shaped opening 1311 of the pallet 131 together with the protruding end of the traction mechanism 400, and transitions to the second conveying station 310 of the second conveying mechanism 300. In this high-speed conveying system 10, the first conveying mechanism 200 and the second conveying mechanism 300 share a traction mechanism 400, which can save the traction mechanism 400, reduce production costs, and ensure that there is no interference during the lifting process.
