Description

Technical Field

[0001] This invention relates to the field of logistics turnover technology, and in particular to a pallet conveying device and system. Background Technology

[0002] In industrial production, the movement of goods within factory workshops is crucial. In existing technologies, due to the considerable height of the goods, if a gantry structure is used, the height of the gantry structure in the lifting direction is more than twice the height of the goods. Without diagonal bracing, the structural stability cannot be guaranteed. However, using a gantry structure with diagonal bracing represents a significant waste of space and is impractical for conventional factory buildings. Therefore, it is necessary to propose further solutions to these problems. Summary of the Invention

Obviously, the drawings described below are only some embodiments recorded in the present invention.

[0021] The present invention will now be described in detail with reference to various embodiments. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent changes or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0022] like Figures 1-3 As shown, an embodiment of the present invention provides a pallet conveying system, which includes: a conveyor 1 and a pallet conveying device 2.

[0023] The pallet conveying device 2 is integrated with the loading and / or unloading ends of the conveyor 1, which includes conveyor chains 11 symmetrically arranged on both sides and extending along the X direction. Thus, continuous loading and / or unloading of goods can be achieved through the pallet conveying device 2.

[0024] The pallet conveying device 2 includes a horizontal drive mechanism 21 and a vertical lifting mechanism 22.

[0025] The horizontal drive mechanism 21 is symmetrically arranged on the left and right sides. The vertical lifting mechanism 22 is provided on the inner side of the horizontal drive mechanism 21 on either side. The horizontal drive mechanism 21 on both sides drives the adjacent vertical lifting mechanism 22 to move synchronously in the X direction.

[0026] Specifically, the horizontal drive mechanism 21 includes a horizontal track body 211, a drive sprocket 212, and a driven sprocket 213. The drive sprocket 212 and the driven sprocket 213 are mounted on the horizontal track body 211 and are linked by a transmission belt 214. The drive sprockets 212 of the horizontal drive mechanisms 21 on both sides are mounted on the same transmission shaft 215, which is driven to rotate by a first motor 216. Thus, by using a common drive motor, it is beneficial to maintain the synchronicity of the horizontal movement of the vertical lifting mechanisms 22 on both sides, and it also simplifies the system structure.

[0027] In addition, to facilitate the horizontal movement of the vertical lifting mechanism 22, a horizontal slide rail 217 suitable for the vertical lifting mechanism 22 to move in the X direction is also provided on the inner side of the horizontal track body 211.

[0028] To connect the horizontal drive mechanism 21 and the vertical lifting mechanism 22, the drive belt 214 of the horizontal drive mechanism 21 is connected to the adjacent vertical lifting mechanism 22 via a connector 218. The connector 218 includes a connector body and pressure blocks at both ends of the connector body. The pressure blocks can be screwed onto the connector body, thus clamping and fixing the end of the drive belt 214 between the pressure blocks and the connector body.

[0029] The upper space between the vertical lifting mechanisms 22 is open to the outside, thus adopting an open design that is not limited by the height of the goods and avoids wasting space. At this time, the loading end and / or unloading end of the conveyor 1 extends into the space between the corresponding horizontal drive mechanisms 21.

[0030] Specifically, the vertical lifting mechanism 22 includes a vertical drive unit 221 and a fork 222. The vertical drive structure drives the fork 222 to move along the Y direction. The fork 222 includes a pivotally mounted fork head 2221.

[0031] The vertical drive unit 221 comprises: a vertical beam 2211, a column 2212, a gear 2213, a rack 2214, and a second motor 2215. The forks 222 are mounted on the front side of the lower end of the vertical beam 2211. The rack 2214 is mounted on one side of the vertical beam 2211. The gear 2213 and the second motor 2215 are mounted on the column 2212 and located on one side of the rack 2214. The gear 2213 can mesh with the rack 2214, and the second motor 2215 drives the gear 2213 to pivot. With this configuration, when the second motor 2215 is working, the linkage between the gear 2213 and the rack 2214 drives the vertical beam 2211 to move up and down along the column 2212.

[0032] In addition, to facilitate the lifting and lowering movement of the upright beam 2211, the column 2212 is also provided with a vertical slide rail suitable for the upright beam 2211 to move along the Y direction.

[0033] The forks 222 are used to carry goods that need to be moved around, and include: fork beams 2222, supports 2223, couplings 2224, and rotary motors 2225. The supports 2223 are pivotally connected to both ends of the fork beams 2222, and each end of the support 2223 is connected to the corresponding rotary motor 2225 via the coupling 2224. The fork tips 2221 are connected to the supports 2223. This design allows for individual adjustment of each fork tip 2221, minimizing the space required for adjustment.

[0034] In summary, the pallet conveying device of the present invention adopts an open design, which is not limited by the height of the goods and avoids wasted space. At the same time, the forks of the present invention employ a structural design that allows individual adjustment of each fork tip, minimizing the space required for adjustment.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
