The chain conveyor has large conveying capacity, and mainly conveys pallets, large turnover boxes and the like. The chain structure is various, and has various accessories, and is easy to realize accumulation and release conveying, and can be used as an assembly production line or as a material storage and conveying.

[0039] In the related art, the driving motor drives the chain on both sides of the chain to rotate through the transmission shaft. However, the driving motor is large in size, and occupies a large installation space.

[0040] In order to solve the above problems, the embodiments of the present application provide a pallet conveying device and a conveying system, which will be described in detail below in combination with the drawings of the specification.

[0041] Fig. 1 is a structural schematic view of a pallet conveying device provided by the embodiments of the present application; Fig. 2 is a schematic view of the transmission assembly 200 in Fig. 1.

[0042] Referring to FIG. 1, in a first aspect, embodiments of the present application provide a tray conveying device, comprising a rack 100, a transmission assembly 200 and an electric roller 300. The transmission assembly 200 is connected to the rack 100. Specifically, the transmission assembly 200 comprises at least two guide wheels 210 and a circulating mechanism 220. The at least two guide wheels 210 are oppositely arranged along a first direction on the rack 100, and the circulating mechanism 220 is arranged around the at least two guide wheels 210. For example, the transmission assembly 200 comprises two guide wheels 210, which are respectively installed on the two ends of the rack 100 through shafts or fixing seats, and are oppositely arranged along the first direction. The circulating mechanism 220 is arranged around the two guide wheels 210.

[0043] It should be noted that the first direction can be indicated by the x direction in FIG. 1. In addition, the electric roller 300 is connected to the rack 100, the electric roller 300 is connected to the circulating mechanism 220, and the electric roller 300 drives the circulating mechanism 220 to rotate around the guide wheel 210. For example, the mounting shafts at the two ends of the electric roller 300 are fixedly installed on the rack 100, the sprocket of the electric roller 300 is connected to the circulating mechanism 220, and the electric roller 300 drives the circulating mechanism 220 to rotate around the guide wheel 210 in the process of rotation.

[0044] It can be understood that, compared with the related art, the tray conveying device of the present application drives the circulating mechanism 220 to rotate by using the electric roller 300, which has low overall structural complexity and is conducive to reducing the overall failure rate. Compared with the design of the driving motor and the transmission shaft in the related art, the electric roller 300 in the tray conveying device of the present application has a smaller volume, which is conducive to saving the overall installation space.

[0045] In addition, for example, the rack 100 comprises a plurality of cross beams and a plurality of longitudinal beams, and the plurality of cross beams and the plurality of longitudinal beams are sequentially connected to constitute the rack 100. Alternatively, the rack 100 can be a steel profile, and specifically in the present embodiment, the cross beams and the longitudinal beams can be steel profiles. In other embodiments, the rack 100 can also be an aluminum profile or a profile of other materials.

[0046] For example, the circulating mechanism can be a chain mechanism or a synchronous belt mechanism, and correspondingly, the guide wheel 210 can be a sprocket or a synchronous belt wheel, which respectively drives the chain mechanism or the synchronous belt mechanism to rotate around it.

[0048] In this example, the electric roller 300 is connected with a chain wheel at each end. The chain wheels at the two ends of the electric roller 300 are connected with the circulating mechanisms 220 of the corresponding transmission assemblies 200. The electric roller 300 drives the circulating mechanisms 220 to rotate through the chain wheels in the process of rotation. It should be noted that the second direction can be indicated by the y direction in FIG. 1.

[0049] In some other examples, the transmission assembly 200 has at least two groups, and the at least two groups of transmission assemblies 200 are arranged on the rack 100 in the second direction with a spacing, and all the circulating mechanisms 220 are connected with the electric roller 300. Specifically, the transmission assembly 200 has two groups, and the guide wheels 210 of the two groups of transmission assemblies 200 are fixedly connected with the two ends of the synchronous shaft, respectively. The chain wheels at the ends of the electric roller 300 are connected with the circulating mechanisms 220 of at least one of the two groups of transmission assemblies 200. That is, the electric roller 300 drives a group of circulating mechanisms 220 to rotate around the corresponding guide wheel 210 through the chain wheel, and the guide wheel 210 drives the circulating mechanisms 220 of the other group of transmission assemblies 200 to rotate through the synchronous shaft.

[0050] In some other examples, the electric roller 300 is arranged at the end of the rack 100, and the two ends of the electric roller 300 are directly or indirectly connected with the corresponding guide wheels, respectively. The electric roller 300 drives the guide wheels 210 to rotate, and the guide wheels 210 rotate to drive the circulating mechanisms 220 to rotate, thereby conveying the tray.

[0051] In some examples, the tray conveying device further comprises at least two support plates, the at least two support plates are fixedly connected with the rack 100, respectively, and all the support plates are located below the upper rotary surfaces of all the circulating mechanisms 220 and are configured to support the upper rotary surfaces of the circulating mechanisms 220. That is, each support plate is located between the upper rotary surface and the lower rotary surface of the corresponding circulating mechanism 220 and is configured to support the upper rotary surface to avoid excessive sagging of the upper rotary surface due to its own gravity and the pressure of the tray.

[0052] Continuing to refer to FIGS. 1 and 2, in some examples, the tray conveying device further comprises two mounting plates 400, the two mounting plates 400 are fixedly mounted on the two sides of the rack 100, are located below the transmission assemblies 200, and the positions of the two mounting plates 400 are opposite.

[0054] For example, the mounting plate 400 is provided with a sliding groove configured to adjust the position of the mounting base 520, and the mounting base 520 can be moved in the sliding groove to select an appropriate fixing position, so that the tensioning wheel 510 on the mounting base 520 can abut against the circulating mechanism 220 and wrap around the sprocket of the electric roller 300. As shown in FIG. 2, the mounting plate 400 is provided with a horizontal sliding groove, and the mounting base 520 can be moved in the horizontal direction along the sliding groove, thereby adjusting the strength of the tensioning wheel 510 abutting against the circulating mechanism 220.

[0055] As shown in FIG. 2, in some other examples, the tensioning assembly 500 is at least two, and the at least two tensioning assemblies 500 are respectively arranged on both sides of the electric roller 300. As shown in FIG. 2, one tensioning assembly 500 is arranged on each of the left and right sides of the tensioning wheel 510, and each tensioning assembly 500 abuts against the circulating mechanism 220 to stably wrap the circulating mechanism 220 around the sprocket of the electric roller 300, thereby ensuring the stable power transmission between the electric roller 300 and the circulating mechanism 220.

[0056] In a second aspect, the embodiments of the present application provide a conveying system comprising the tray conveying device of the first aspect. Since the conveying system comprises the tray conveying device in any of the above technical solutions, it has all the beneficial effects of the electric roller 300 in any of the above technical solutions, which will not be repeated here.

[0057] It is easy to understand that, based on the several embodiments provided by the present application, the embodiments of the present application can be combined, split, recombined, etc. to obtain other embodiments, which do not exceed the protection scope of the present application.
