[0032] Please refer to Figures 1 to 10 as shown, which is an embodiment of the present utility model. As Figures 1 to 3 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 successively 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.

[0033] The storage device 1 includes a shelf 11 and a movable gate 12 installed 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 can also be suspended according to actual needs.

[0034] In this embodiment, the shelf 11 includes a frame 111 and a plurality of storage plates 112 mounted on the frame 111, and any two adjacent storage plates 112 together define a storage chamber S1. Among them, the frame 111 is formed by fixing and assembling a plurality of rods, and each storage plate 112 is horizontal and fixed within the frame 111. That is to say, each storage chamber S1 can also be regarded as being composed of two adjacent storage plates 112 and the part of the frame 111 that fixes them.

[0035] More specifically, the plurality of storage plates 112 are arranged at equal intervals, and two avoidance grooves 1122 adjacent to the corresponding entrance / exit S11 are recessed in one storage plate 112 located above each storage chamber S1. In this embodiment, each storage plate 112 includes two sub-storage plates 1121 arranged at intervals, and two of the avoidance grooves 1122 are respectively formed in the two sub-storage plates 1121. That is to say, each storage plate 112 has a communication space 1123 left between the two sub-storage plates 1121, so that any two adjacent storage chambers S1 can communicate with each other in the height direction H through the communication space 1123.

[0036] It should be additionally noted that the periphery of each storage chamber S1 is non-closed (or open) in this embodiment, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention

[0037] the storage plate 112 can be a single plate body, so that the upper and lower sides of the storage chamber S1 are both closed; or, the storage chamber S1 can also only communicate the entrance / exit S11 with the outside, and the storage chamber S1 is closed in the directions other than the entrance / exit S11.

[0038] The movable gate 12 includes a gate body 121 and a driving mechanism 122, and the position of the gate body 121 generally falls on the front side of the plurality of storage chambers S1 (such as: the front side of the plurality of entrance / exit S11), and the driving mechanism 122 is installed on the shelf 11 (such as: the driving mechanism 122 is fixed to the top edge of the frame 111) and connected to the gate body 121 (at the top edge).

[0039] Among them, the driving mechanism 122 can drive the gate body 121 to move in the height direction H, so that the movable gate 12 can selectively be located at a goods storage position (such as: Figure 1 and Figure 4 shown) and a goods loading position (such as: Figure 8 andFigure 10 One of the structures as shown in the figure. In this embodiment, the driving mechanism 122 includes a driving motor 1221 fixed to the frame 111 and a swing arm group 1222 connecting the driving motor 1221 and the door body 121. However, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the driving mechanism 122 can also be implemented in other driving manners (such as: a motor paired with a gear set).

[0040] More specifically, in this embodiment, the door body 121 includes two side rods 1211, a plurality of linear guiding blocks 1212 respectively installed on the outer sides of the two side rods 1211, a plurality of toggle rods 1213 connected between the two side rods 1211, and a transmission rod 1214 connected between the two side rods 1211 and located above the plurality of toggle rods 1213. Among them, the driving mechanism 122 (such as the swing arm group 1222) is connected to the transmission rod 1214, and the plurality of linear guiding blocks 1212 respectively (slidingly) abut against the frame 111, so that the door body 121 can (be driven by the driving mechanism 122 to) linearly move along the height direction H.

[0041] Furthermore, the plurality of toggle rods 1213 are respectively located in front of the entrances and exits S11 of the plurality of storage chambers S1, and each toggle rod 1213 is adjacent to the two avoidance slots 1122 of the corresponding storage plate 112. Among them, the movable shutter 12 can move from the goods storage position (such as Figure 1 and Figure 4 as shown) to the goods loading position (such as Figure 8 and Figure 10 as shown), so that each toggle rod 1213 moves closer to the top edge of the corresponding storage chamber S1. That is to say, when the movable shutter 12 is in the goods loading position, each toggle rod 1213 does not block the entrance and exit S11 of the corresponding storage chamber S1; while when the movable shutter 12 is in the goods storage position, each toggle rod 1213 blocks the entrance and exit S11 of the corresponding storage chamber S1.

[0042] It should be additionally noted that in this embodiment, the shelf 11 is described with a plurality of storage chambers S1 arranged in a row and one movable shutter 12, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the shelf 11 can also be configured with a plurality of storage chambers S1 arranged in multiple rows according to actual needs and at least one movable shutter 12.

[0043] In this embodiment, the shelf 11 is described with a plurality of storage chambers S1 arranged in a row and one movable shutter 12, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the shelf 11 can also be configured with a plurality of storage chambers S1 arranged in multiple rows according to actual needs and at least one movable shutter 12.

[0044] In this embodiment, the automated guided vehicle 2 includes a traveling module 21, a temporary storage module 22 mounted on the traveling module 21, and a cargo holding module 23 that is liftably mounted on the temporary storage module 22. Among them, the specific structures of the traveling module 21 and the cargo holding module 23 can be adjusted and changed according to actual needs, and will not be elaborated herein in the present utility model. 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 an object placing mechanism that may optionally not be equipped with any forks, and 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 utility model is not limited thereto. For example, in other embodiments not shown in the present utility model, the automated guided vehicle 2 can also place the cargo M into one of the temporary storage spaces S2 through other mechanisms.

[0045] More specifically, 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, a plurality of load plates 223 respectively fixed to the plurality of cross bars 222, and a plurality of pairs of side stoppers 224. Among them, the bracket 221 is generally U-shaped and is vertically fixed to the traveling module 21, the plurality of cross bars 222 are fixed inside the bracket 221 and are arranged along the height direction H, and the plurality of cross bars 222 may optionally be arranged at equal intervals.

[0046] Furthermore, one end of each load plate 223 is fixed to the corresponding cross bar 222, so that the other end of each load plate 223 is in a suspended state, and the width of each load plate 223 may optionally be less than the distance between the two sub-storage plates 1121 of the storage plate 112. In addition, any two adjacent load plates 223 together define a temporary storage space S2, and each load plate 223 is used to carry a cargo M (transmitted by the cargo holding module 23) thereon, so that the cargo M is located within the corresponding temporary storage space S2.

[0047] Each pair of side stoppers 224 is mounted on a load plate 223 on the upper side of a temporary storage space S2 to prevent the corresponding cargo M from lateral displacement. In this embodiment, each pair of side stoppers 224 is rotatably connected to the corresponding load plate 223, and each side stopper 224 may be circular and is rotatably connected to the corresponding load plate 223 along an axis C at an eccentric position.

[0048] It should be additionally noted that in this embodiment, the load plate 223 on the upper side of any temporary storage space S2 may be mounted with two pairs of side stoppers 224 arranged at intervals, so that the two pairs of side stoppers

[0049] 224 can effectively prevent the lateral displacement of the corresponding goods M from the four corners of the goods M, but the present invention is not limited thereto.

[0050] As described above, when the movable gate 12 is located at the goods loading position (such as: Figure 1 and Figure 4 shown), the automatic guided vehicle 2 can move towards the storage device 1 so that the plurality of temporary storage spaces S2 respectively pass through the plurality of entrances S11 and enter the plurality of storage chambers S1 respectively (such as: Figure 8 and Figure 10 shown), whereby the goods M located in any one of the temporary storage spaces S2 can be carried by one of the load plates 223 and placed into the corresponding storage chamber S1.

[0051] Furthermore, when the plurality of temporary storage spaces S2 of the automatic guided vehicle 2 are respectively located within the storage chambers S1, the movable gate 12 can move from the goods loading position (such as: Figure 1 and Figure 4 shown) to the goods storage position (such as: Figure 8 and Figure 10 shown), so that during the process of the automatic guided vehicle 2 moving away from the storage device 1, the plurality of lever rods 1213 can force the goods M located in any one of the temporary storage spaces S2 to be blocked and stay within the corresponding storage chamber S1.

[0052] Thus, in this embodiment, the loading and unloading system 100 enables the goods M within the plurality of temporary storage spaces S2 to be synchronously unloaded into the plurality of storage chambers S1 by the power during the movement of the automatic guided vehicle 2 through the structural cooperation between the storage device 1 and the automatic guided vehicle 2, thereby effectively simplifying the overall mechanism of the loading and unloading system 100 and reducing its manufacturing and maintenance costs.

[0053] In addition, in order to make the loading and unloading of the goods M between the storage device 1 and the automatic guided vehicle 2 smoother, the storage device 1 and the automatic guided vehicle 2 in this embodiment have at least some of the following technical features, but the present invention is not limited thereto.

[0054] Specifically, as Figures 4 to 8As shown, when the automated guided vehicle 2 moves towards the storage device 1 such that the plurality of temporary storage spaces S2 respectively pass through the plurality of entrances S11 and enter the plurality of storage chambers S1, the height position of the axis C of each pair of the side flaps 224 is higher than the height position of the corresponding lever 1213. Thus, each pair of the side flaps 224 can rotate along a lever 1213 and climb over the corresponding lever 1213, so that the plurality of temporary storage spaces S2 respectively enter the corresponding plurality of storage chambers S1. At this time, each load plate 223 is located between two corresponding sub-storage plates 1121 (that is, each load plate 223 is within the communication space 1123 of the corresponding storage plate 112).

[0055] Further, when each pair of the side flaps 224 rotates along the corresponding lever 1213, each pair of the side flaps 224 can first penetrate into the two avoidance grooves 1122, and then climb over the corresponding

[0056] lever 1213 and enter the corresponding storage chamber S1. Thus, each storage plate 112 can effectively avoid the mutual interference between the side flaps 224 and the sub-storage plates 1121 by forming two avoidance grooves 1122 that can cooperate with the position of the axis C of the corresponding pair of side flaps 224.

[0057] [Technical effects of the embodiments of the present utility model]

[0058] In summary, for the loading and unloading system disclosed in the embodiments of the present utility model, through the structural cooperation between the storage device and the automated guided vehicle, the goods within the plurality of temporary storage spaces can be synchronously unloaded into the plurality of storage chambers by the power during the movement of the automated guided vehicle, thereby effectively simplifying the overall mechanism of the loading and unloading system and reducing its manufacturing and maintenance costs.

[0059] The content disclosed above is only the optional and feasible embodiments 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.
