[0032] [Embodiment 1]

[0033] Please refer to Figures 1 to 10 as shown, which is Embodiment 1 of the present utility model. As Figure 1 and Figure 2 shown, this embodiment discloses a loading and unloading system 100, which includes a storage device 1 and an automated guided vehicle 2 that can move relative to the storage device 1. That is to say, the loading and unloading system 100 in this embodiment is an automated operating system, and the following content will sequentially describe the structures of the storage device 1 and the automated guided vehicle 2, and then introduce the operating relationship between the storage device 1 and the automated guided vehicle 2 in due course.

[0034] The storage device 1 includes a shelf 11 and at least one guiding structure 12 disposed on the shelf 11. Among them, the shelf 11 is used to be arranged on a ground G, and the shelf 11 is formed with a plurality of storage chambers S1 arranged along a height direction H, and each of the plurality of storage chambers S1 has an entrance and exit S11, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the shelf 11 may also be suspended according to actual needs.

[0035] It should be additionally noted that the shelf 11 in this embodiment is described by a plurality of the storage chambers S1 arranged in a row, but the present utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the shelf 11 may also be configured with a plurality of the storage chambers S1 arranged in multiple rows according to actual needs.

[0036] At least one of the guiding structures 12 is disposed corresponding to the entrance and exit S11 of at least one of the storage chambers S1, and at least one of the guiding structures 12 may optionally be disposed at a corner position of the corresponding entrance and exit S11, but the present utility model is not limited thereto. Further, the number of at least one of the guiding structures 12 is multiple in this embodiment, and each of the guiding structures 12 is disposed corresponding to one entrance and exit S11. Moreover, the number of the multiple guiding structures 12 can be configured to be equal to the number of the multiple storage chambers S1 according to actual needs (such as: Figure 1 shown) or less than the number of the multiple storage chambers S1 (such as:Figure 3 as shown

[0037] In addition, since the plurality of guiding structures 12 adopt substantially the same configuration in this embodiment, for the convenience of description, the following content will only introduce the configuration of one of the guiding structures 12, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the plurality of guiding structures 12 may adopt slightly different configurations according to actual needs.

[0038] In this embodiment, as Figures 4 to 6 shown, the guiding structure 12 has a mounting portion 121 and a guiding plate 122 integrally connected to the mounting portion 121. The mounting portion 121 is fixed to the shelf 11 and at least partially located within the corresponding entrance / exit S11, while the guiding plate 122 is located outside the corresponding storage chamber S1. Wherein, the mounting portion 121 and the guiding plate 122 may be an integral structure formed by bending a metal plate, but the present invention is not limited thereto.

[0039] More specifically, the mounting portion 121 has an extending surface 123, at least a part of which is located within the corresponding entrance / exit S11. The guiding plate 122 has a guiding inclined surface 124, which extends from the extending surface 123 in a direction away from the corresponding entrance / exit S11, and an included angle σ between 135 degrees and 170 degrees is formed between the guiding inclined surface 124 and the extending surface 123. Wherein, although the guiding inclined surface 124 is illustrated as a plane in this embodiment, in other embodiments not shown in the present invention, the guiding inclined surface 124 may also be a convex curved surface or a concave curved surface.

[0040] As Figure 1 and Figures 4 to 6 shown, the automated guided vehicle 2 in this embodiment includes a traveling module 21, a temporary storage module 22 installed on the traveling module 21, a cargo holding module 23 installed on the temporary storage module 22 in a liftable manner, and a stop module 24 installed on the temporary storage module 22. It should be noted that the specific configurations of the traveling module 21 and the cargo holding module 23 can be adjusted and changed according to actual needs, and the present invention will not elaborate thereon here.

[0041] Furthermore, the traveling module 21 is used to move on the ground G. The temporary storage module 22 is formed with a plurality of temporary storage spaces S2 and is optionally a storage mechanism without any forks. The cargo holding module 23 can be used to place a cargo M into one of the temporary storage spaces S2 of the temporary storage module 22, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the automated guided vehicle 2 can also place the cargo M into one of the temporary storage spaces S2 through other mechanisms.

[0042] The temporary storage module 22 includes a bracket 221 fixed to the traveling module 21, a plurality of cross bars 222 fixed to the bracket 221, and a plurality of loading platforms 223 respectively fixed to the plurality of cross bars 222. Among them, the bracket 221 is generally U-shaped and is vertically fixed to the traveling module 21 at both ends thereof. The plurality of cross bars 222 are fixed inside the bracket 221 and arranged along the height direction H, and the plurality of cross bars 222 are optionally arranged at equal intervals.

[0043] Furthermore, one end of each loading platform 223 is fixed to the corresponding cross bar 222, so that the other end of each loading platform 223 is in a suspended state. Any two adjacent loading platforms 223 together define one temporary storage space S2, and each loading platform 223 has a front opening 2231 and a rear opening 2232 located on opposite sides. Among them, each loading platform 223 is used to carry one cargo M (transmitted by the cargo holding module 23 from the front opening 2231) thereon, so that the cargo M is located in the corresponding temporary storage space S2.

[0044] The stop module 24 is located on one side of the plurality of rear openings 2232, and the position of the stop module 24 generally corresponds to the plurality of guiding structures 12. The stop module 24 includes a plurality of bases 241 respectively fixed to the plurality of loading platforms 223, a plurality of stop bars 242 respectively pivotally connected to the plurality of bases 241, a lever 243 pivotally connected to the plurality of stop bars 242, a plurality of springs 244 connecting the plurality of stop bars 242 and the lever 243, and at least one activating member 245 installed on the lever 243, but the present invention is not limited thereto.

[0045] It should be noted first that the height position of at least one of the starting members 245 corresponds to the height position of at least one of the guiding structures 12. In this embodiment, the number of at least one starting member 245 is multiple, each starting member 245 corresponds to one of the rear openings 2232, and the height positions of the multiple starting members 245 respectively correspond to the height positions of the multiple guiding structures 12. Furthermore, the number of the multiple starting members 245 can be configured to be equal to the number of the multiple rear openings 2232 according to actual requirements (such as: Figure 1 as shown) or less than the number of the multiple rear openings 2232 (such as: Figure 3 as shown).

[0046] In addition, based on the fact that the multiple components of the stop module 24 corresponding to the multiple rear openings 2232 (such as each group of components includes a base 241, a corresponding stop rod 242, a corresponding shift lever 243, a corresponding spring 244, and a corresponding starting member 245) are substantially the same in this embodiment, for the convenience of description, the following content will only introduce one component of the stop module 24, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the multiple components of the stop module 24 may adopt slightly different structures according to actual requirements.

[0047] The base 241 is fixed outside the side wall of the corresponding loading platform 223, and the pivot joint of the base 241 and the stop rod 242 is located outside the corresponding rear opening 2232. The stop rod 242 is in a long strip shape and includes a stop end 2421 and a linkage end 2422 respectively located at opposite ends, and the linkage end 2422 is pivotally connected to the shift lever 243 and is adjacent to the starting member 245 (that is, the multiple shift levers 243 are respectively pivotally connected to the linkage ends 2422 of the multiple stop rods 242, and each starting member 245 is adjacent to one linkage end 2422), and the stop end 2421 is adjacent to the corresponding rear opening 2232.

[0048] Furthermore, one end of the spring 244 is installed on the stop end 2421, and the other end of the spring 244 is fixed to the shift lever 243 (that is, one ends of the multiple springs 244 are respectively installed on the multiple stop ends 2421, and the other ends of the multiple springs 244 are respectively fixed to the shift levers 243). In addition, the starting member 245 in this embodiment includes a wheel seat 2451 fixed to the shift lever 243 and a roller 2452 pivotally connected to the wheel seat 2451, but the present invention is not limited thereto.

[0049] Furthermore, the stop module 24 can be configured as described above so that the lever 243 can be moved between a stop position (e.g., as shown in Figure 5 and Figure 6 ) and a unloading position (e.g., as shown in Figure 9 and Figure 10 ). When the lever 243 is in the stop position, each stop end 2421 blocks the corresponding rear opening 2232, and the pre-pressure of the plurality of springs 244 tends to drive the lever 243 to the stop position. Moreover, at least one starting member 245 can be pressed to force the lever 243 to move from the stop position to the unloading position, so that the plurality of stop rods 242 rotate synchronously, and each stop end 2421 leaves the corresponding rear opening 2232.

[0050] As described above, when the automated guided vehicle 2 moves towards the storage device 1 and the plurality of loading platforms 223 are respectively adjacent to the entrances S11 of the plurality of storage chambers S1 (e.g., as shown in Figure 5 and Figure 6 ), at least one starting member 245 can move by abutting against and along at least one guiding structure 12 (as shown in Figure 7 and Figure 8 , each starting member 245 can move by abutting against and along one guiding structure 12) to force the lever 243 to move from the stop position to the unloading position, so that the plurality of stop rods 242 rotate synchronously, and each stop end 2421 leaves the corresponding rear opening 2232 (e.g., as shown in Figure 9 and Figure 10 ). In this embodiment, any one of the starting members 245 can move by (the roller 2452) abutting against and successively along the guiding inclined surface 124 and the extending surface 123 of the corresponding guiding structure 12 to force the lever 243 to move from the stop position to the unloading position, which is beneficial for the goods M to be transported to the storage device 1.

[0051] Thus, in this embodiment, the loading and unloading system 100 (or the automated guided vehicle 2) can prevent the goods M from falling at the rear opening 2232 of the loading platform 223 by adding the rear opening 2232 to each loading platform 223 and configuring the stop module 24.

[0052] Furthermore, the loading and unloading system 100 also, through the structural cooperation between the storage device 1 and the automated guided vehicle 2, enables the stop module 24 to be driven by the corresponding guiding structure 12 to move away from the corresponding rear opening 2232 via the power generated when the automated guided vehicle 2 moves, thereby facilitating the transportation of the goods M to the storage device 1.

[0053] In addition, to make the loading and unloading of the goods M between the storage device 1 and the automated guided vehicle 2 smoother, the automated guided vehicle 2 can, through the arrangement of a plurality of springs 244, facilitate the movement of the lever 243 from the unloading position to the stop position. Further, when the lever 243 moves from the stop position to the unloading position, the plurality of springs 244 are compressed and store a restoring elastic force. Moreover, when the automated guided vehicle 2 moves in a direction away from the storage device 1 to cause the lever 243 to leave the unloading position, the restoring elastic force of the plurality of springs 244 is released and drives the lever 243 to move towards the stop position.

[0054] [Embodiment 2]

[0055] Please refer to Figures 11 to 13 as shown, which is Embodiment 2 of the present utility model. Since this embodiment is similar to Embodiment 1 above, the similarities between the two embodiments will not be elaborated further, and the differences between this embodiment and Embodiment 1 above are generally described as follows:

[0056] This embodiment discloses a loading and unloading system 100, which includes a storage device 1 and an automated guided vehicle 2 that can move relative to the storage device 1. Among them, the storage device 1 in this embodiment is constructed as shown in Figure 1 Embodiment 1, so the following content will not be elaborated further. Furthermore, the automated guided vehicle 2 in this embodiment is constructed similarly to that in Figure 1 Embodiment 1, and the similarities between the two are not elaborated further, while the difference mainly lies in that: the automated guided vehicle 2 in this embodiment includes a plurality of stop modules 24.

[0057] Further, the plurality of components used in the plurality of stop modules 24 in this embodiment are similar to the plurality of components used in the stop module 24 in Embodiment 1, but the plurality of components of the plurality of stop modules 24 in this embodiment are spaced apart from each other and can operate independently, while the plurality of components of the stop module 24 in Embodiment 1 can operate synchronously through the rotation of any one of the levers 243.

[0058] In this embodiment, a plurality of the stop modules 24 are respectively located on one side of a plurality of the rear openings 2232, and the plurality of the stop modules 24 adopt a substantially identical structure and are similar to the structure of one component of the stop module 24 in the first embodiment. Therefore, the following content only briefly describes the structure of one of the stop modules 24, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the plurality of the stop modules 24 may also adopt structures that are slightly different from each other according to actual requirements.

[0059] More specifically, in this embodiment, the temporary storage module 22 includes a base 241 fixed to the corresponding carrier 223, a stop lever 242 pivotally connected to the base 241, a spring 244 connecting the stop lever 242 and the lever 243, and an actuator 245 installed on the lever 243, but the present invention is not limited thereto. Among them, the stop lever 242 includes a stop end 2421 and a linkage end 2422 located at opposite ends respectively. The lever 243 is pivotally connected to the linkage end 2422 of the stop lever 242. The actuator 245 is adjacent to the linkage end 2422 and its height position corresponds to one of the guiding structures 12 (that is, the height positions of the actuators 245 of the plurality of the stop modules 24 respectively correspond to the height positions of the plurality of the guiding structures 12).

[0060] Through the above configuration, the stop module 24 can enable the lever 243 to move between a stop position (as shown in, for example: Figure 12 shown) and a discharging position (as shown in, for example: Figure 13 shown). When the lever 243 is located at the stop position, the stop end 2421 blocks the corresponding rear opening 2232, and the pre-pressure of the spring 244 tends to drive the lever 243 to be located at the stop position. Furthermore, the actuator 245 can be pressed to force the lever 243 to move from the stop position to the discharging position, so that the stop lever 242 rotates synchronously, and the stop end 2421 leaves the corresponding rear opening 2232.

[0061] As described above, when the automated guided vehicle 2 moves towards the storage device 1 and the plurality of carriers 223 are respectively adjacent to the entrances and exits S11 of the plurality of storage chambers S1, the plurality of actuators 245 can respectively abut against and move along the plurality of guiding structures 12 to force each lever 243 to move from the stop position to the discharging position, so that the plurality of stop levers 242 rotate synchronously, and each stop end 2421 leaves the corresponding rear opening 2232.

[0062] [Technical effects of the embodiments of the present invention]

[0063] In summary, for the loading and unloading system and the automated guided vehicle disclosed in the embodiments of the present utility model, by adding the rear opening to each of the load platforms and configuring the stop module, the goods can be stopped from falling at the rear opening of the load platform. Furthermore, through the structural cooperation between the storage device and the automated guided vehicle, the stop module can be driven by the corresponding guiding structure to leave the corresponding rear opening via the power during the movement of the automated guided vehicle, so as to facilitate the transportation of the goods to the storage device.

[0064] The content disclosed above is only an optional and feasible embodiment of the present utility model, and does not limit the patent scope of the present utility model. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present utility model are included in the patent scope of the present utility model.
