[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Figure 1 FIG. 2 shows a schematic structural diagram of the loading and unloading system of this embodiment. Figure 2 A schematic diagram of the top structure of the loading and unloading system of this embodiment is shown.

[0047] Combination Figure 1 and Figure 2 As shown, the loading and unloading system of this embodiment includes a carrying portion 8 for carrying a container 9 to be loaded or unloaded, a loader 4 that can enter the container 9, and a platform 6 extending along a first direction toward the carrying portion 8, and the platform 6 is for the loader 4 to move in and out of the container 9.

[0048] The loading and unloading system further includes a parking position for parking a vehicle 10 for transporting the container 9, and the parking position is arranged side by side with the load-bearing portion 8 to facilitate the transfer of the container 9 between the load-bearing portion 8 and the vehicle 11 for transporting the container 9. Optionally, the parking position and the load-bearing platform 8 are arranged along a second direction perpendicular to the first direction, and by reasonably arranging the positions of the parking position, the load-bearing portion 8 and the platform 6, the layout of the loading and unloading system is made more compact and reasonable, which is conducive to saving space and facilitating the entry and exit of the vehicle 11.

[0049] The loading and unloading system further comprises a crane 11 for transferring the container 9 between the vehicle 10 and the load-bearing portion 8. The crane 11 comprises a sling mounted on a support, and the sling is used to connect the container 9. The sling can move relative to the support in a second direction to transfer the container 9 between the vehicle 10 and the load-bearing portion 8. Of course, the crane can also be other types of lifting equipment.

[0050] In order to enable the loader 4 to smoothly enter the containing body 9 to perform operations along a predetermined route, the loading and unloading system also includes a limiting component 8a provided on the bearing portion 8, and the limiting component 8a is used to limit the position of the containing body 9 on the bearing portion 8. The limiting component 8a limits the containing body 9 to a predetermined position, which is conducive to the loader 4 entering the containing body 9 along the predetermined route, thereby improving the problem of the cumbersome positioning process of the loader in the prior art.

[0051] The limiting component 8a includes a first limiting component provided at one end of the accommodating body 9 along the first direction, and the first limiting component is used to limit the position of the accommodating body 9 in the first direction. Optionally, first limiting components are provided at both ends of the accommodating body 9 along the first direction.

[0052] The limiting component 8a further includes a second limiting component provided at one end of the accommodating body 9 along the second direction, and the second limiting component is used to limit the position of the accommodating body 9 in the second direction, and the second direction is perpendicular to the first direction.

[0053] The first limiting component and the second limiting component are arranged around the accommodating body 9 to limit the accommodating body 9 to a predetermined position.

[0054] The limiting component 8a is erected on the bearing surface of the bearing portion 8 and is inclined in the direction away from the bearing surface and away from the containing body 9. The inclined surface of the limiting component 8a facing the containing body 8a forms an introduction surface, which is conducive to the containing body 9 falling into the space enclosed by the limiting component 8a.

[0055] like Figure 1 As shown, the platform 6 and the bearing part are spaced apart, and the loading and unloading system further comprises a bridging platform 7 disposed between the platform 6 and the bearing part 8, and the height of the bridging platform 7 is adjustable. The door of the container 9 is located at one end of the container 9 adjacent to the bridging platform, and when the door of the container 9 needs to be opened or closed, the bridging platform 7 is lowered to avoid the door during the opening and closing process.

[0056] like Figure 1 and 2 As shown, the loading and unloading system further comprises a depalletizing station 2 and a first conveying line 3 for conveying the depalletized goods to the loader 4 in the containing body 9. The first conveying line 3 can be extended and retracted along a first direction to adjust the conveying distance during the operation of the loader 4.

[0057] The depalletizing station 2 includes a depalletizing device 203, a second conveyor line 202 for conveying goods to be depalletized to the depalletizing device 203, and a transport component 201 for transporting the goods stack by the second conveyor line 202, wherein the transport component 201 includes one of a transport vehicle and a conveyor belt. The depalletizing device 203 is provided with a goods image acquisition device 205 and a depalletizing fixture 204. The depalletizing device 203 may be a depalletizing robot or a servo handling platform.

[0058] The depalletizing station 2 also includes a goods receiving and temporary storage conveyor line 206 and a goods separation conveyor line 207 for transferring the depalletized goods to the first conveyor line 3.

[0059] The depalletizing station 2 also includes a steering mechanism 208 for adjusting the direction of the goods. Optionally, the steering mechanism 208 is arranged downstream of the goods separation conveying line 207.

[0060] Combination Figures 1 to 3 As shown, the loading and unloading system further comprises a guide rail 5 mounted on the platform 6. The guide rail 5 can move relative to the platform 6 to extend into the accommodating body 9. The guide rail 5 guides the loader 4 to the interior of the accommodating body 9 along a predetermined route.

[0061] In this embodiment, the container 9 is positioned by a limiting component 8a provided on the bearing portion 8, and the guide rail 5 guides the loader 4 into the container 9 along a predetermined route, further determining the relative position of the loader 4 and the container 9 to ensure that the loader 4 can operate smoothly in the container 9.

[0062] Figure 4 It shows a schematic diagram of the top view of the platform 6, the bridging platform 7, the container 9 and the loader and unloader, Figure 5 Shows Figure 4 Schematic diagram of the cross-sectional structure at platform 6.

[0063] Combination Figure 4 and Figure 5 As shown, the loader 4 is equipped with a first positioning wheel 15, and the loader 4 moves on the guide rail 5 via the first positioning wheel 15. Figure 5 As shown, the side of the guide rail 5 is provided with a convex edge, the first positioning wheel 15 is located above the convex edge, and the loader 4 is also equipped with a second positioning wheel 16 located below the convex edge. The first positioning wheel 15 and the second positioning wheel 16 are connected to the loader 4 through a connecting frame 17.

[0064] The first positioning wheel 15 and the second positioning wheel 16 are respectively located above and below the guide rail 5 , so that the loading and unloading vehicle 4 is fixed relative to the guide rail in the vertical direction, thereby preventing the loading and unloading vehicle 4 from being separated from the guide rail 5 .

[0065] The loading and unloading system further comprises a driving unit for moving the guide rail 5 relative to the platform 6 in a first direction, the driving unit comprising a rack 12 and a gear 13 meshing with the rack 12, one of the rack 12 and the gear 13 being mounted on the guide rail 5. Preferably, the rack 12 is mounted on one side of the guide rail 5.

[0066] The driving unit further includes a motor 14 for driving the gear 13 to rotate. During the rotation of the gear 13 , the gear 13 engages with the rack 12 to drive the guide rail 5 to move relative to the platform 6 along the first direction.

[0067] like Figure 5 As shown, the front end of the guide rail 5 firstly enters the containing body 9 and is provided with a support wheel 21. After the guide rail is extended into the containing body 9, the front end of the guide rail 5 becomes a free end. The front end of the guide rail 5 can be supported by the support wheel 21 to improve the bearing capacity of the guide rail 5 and also facilitate the smooth movement of the guide rail. Optionally, the height of the support wheel 21 is adjustable to adapt to the containing body 9 with different bottom wall thicknesses.

[0068] The loading and unloading system further comprises a guide component 18 mounted on the guide component 6 on the platform 6, for guiding the guide rail 5 to move along the first direction. Optionally, a guide component 18 is also provided on the bridging platform 7.

[0069] The guide member 18 includes a roller which is arranged on a side of the guide rail 5 facing away from the rack 12 .

[0070] Since the portion of the guide rail 5 extending into the accommodating body 9 cannot be guided by the guide component 18 , the front end of the guide rail 5 may deviate from the first direction, so the support wheel 21 includes a steering wheel for adjusting the direction of the guide rail 5 .

[0071] After the guide rail 5 deviates from the first direction, the loader 4 will also deviate from the first direction along with the guide rail, thereby affecting the normal operation of the loader 4. To solve this problem, the loading and unloading system also includes a detection unit for detecting whether the loader 4 is skewed relative to the containing body 9.

[0072] The detection unit includes two first distance detection components 19 respectively arranged on both sides of the loader 4, and the first distance detection components 19 are used to detect the distance between the loader 4 and the side wall of the container 4. The detection unit also includes a controller, and the controller is used to determine whether the loader 4 is biased to one side of the container 9 according to the data detected by the two first distance detection components 19. The controller determines whether the loader 4 is biased to one side of the container 9 according to the distance difference detected by the two first distance detection components. The detection unit can also be other types of detection devices, such as an angle sensor, etc.

[0073] Preferably, two first distance detection components 19 are provided at the front end of the loader 4 that first enters the containing body 9 , so as to detect whether the loader 4 is deflected relative to the containing body 9 at the first time.

[0074] The detection unit also includes two second distance detection components 20 respectively arranged on both sides of the loader 4, the second distance detection components 20 are used to detect the distance between the loader 4 and the side wall of the container 9, and the second distance detection component 20 and the first distance detection component 19 are arranged side by side along the travel direction of the loader 4.

[0075] The controller is also used to determine whether the loader 2 is deflected relative to the accommodating body 2 based on the data detected by the first distance detecting component 19 and the second distance detecting component 20 .

[0076] The controller can calculate the angle between the loader 4 and the first direction according to the difference between the data detected by the first distance detecting component 19 and the data detected by the second distance detecting component 20 and the distance between the first distance detecting component 19 and the second distance detecting component 20 .

[0077] The loading and unloading system further comprises a steering part for adjusting the position of the loading and unloading machine 4 in the containing body 9 , so as to adjust the position of the loading and unloading machine 4 when the loading and unloading machine 4 is deflected relative to the containing body 9 .

[0078] The steering part includes a driving component 22 connected to the loader 4. The driving component 22 includes a moving part that moves in a direction away from the loader 4. The moving part is used to push the containing body 9 to make the loader 4 adjust its direction.

[0079] Optionally, the drive component comprises a hydraulic cylinder.

[0080] Both sides of the loader 4 are provided with driving components 22. The driving components 22 include a first driving component and a second driving component arranged side by side along the travel direction of the loader 4. The two first driving components are at the same position in the travel direction of the loader 4. The two second driving components are at the same position in the travel direction of the loader 4.

[0081] When the detection unit detects that the loader 4 is deflected relative to the container 9, the controller controls the driving component 22 to push the side wall of the container 9. The supporting wheel 5 turns under the force of the driving component 22 to adjust the direction of the loader 4.

[0082] like Figure 1 As shown, the loading and unloading system also includes a control system 1 for controlling the loading and unloading system to perform operations. The control system completes the loading and unloading tasks by controlling the coordinated operations of various devices in the loading and unloading system. Figure 6 The flowchart of the loading and unloading system of this embodiment is shown.

[0084] Figure 7 A schematic structural diagram of the loading and unloading system of this embodiment is shown; Figure 8FIG. 2 shows a schematic diagram of the top view of the loading and unloading system of this embodiment, Fig. 9 A partial enlarged view of the loading and unloading system of this embodiment is shown.

[0085] Combination Figures 7 to 9 As shown, the difference between this embodiment and the first embodiment is that an end of the bearing portion 8 close to the platform 6 is higher than an end of the bearing portion 8 far from the platform 6 .

[0086] When the loader 4 enters the container 9 along the platform 6 to load and unload goods, the goods may also tip over to the side where the loader 4 is located. The side of the load-bearing portion 8 close to the platform 6 is higher, which can make the goods tip over to the side wall of the container 9 away from the platform 6, thereby solving the problem of cargo tipping over.

[0087] Optionally, the angle between the bearing surface of the bearing portion 8 for bearing the containing body 9 and the horizontal direction is 1° to 5°. For goods that are particularly easy to tip over, the angle may be 5° to 10°.

[0088] Fig.10 Shows Fig. 9 The schematic diagram of the partial top view of the loading and unloading system shown in FIG. Fig.11 Shows Fig. 9 Schematic diagram of the cross-sectional structure at the middle platform.

[0089] Combination Fig.10 and Fig.11 As shown, this embodiment is different from the first embodiment in that a rack 12 and a gear 13 are provided on both sides of the guide rail 5. Optionally, the two gears 13 respectively provided on both sides of the guide rail 5 are driven by the same motor 14.

[0090] Embodiment 3

[0091] Fig.12 The schematic diagram of the structure of the loading and unloading system of this embodiment is shown. Fig.13 Shows Fig.12 A schematic diagram of the top view of the loading and unloading system is shown. Fig.14 A partial structural schematic diagram of the loading and unloading system of this embodiment is shown.

[0092] The difference between this embodiment and the first embodiment is that the loader 4 is a railless loader, which includes a wheeled traveling mechanism or a crawler traveling mechanism.

[0093] The driving component 22 arranged on the first side of the loader and unloader 4 includes a motor 221 and a first plate-shaped component 223 for pushing the side wall of the containing body 9. The motor 221 drives the first plate-shaped component 223 to move along the width direction of the loader and unloader 4 through a threaded transmission mechanism, so as to adjust the direction of the loader and unloader 4 by pushing the side wall of the containing body 9 when the loader and unloader 4 is deflected relative to the containing body 9.

[0094] The driving component 22 provided on the second side of the loader 4 includes a cylinder or a hydraulic cylinder, and the end of the piston of the cylinder or the hydraulic cylinder is connected to a second plate-shaped component. When the loader is deflected relative to the container 9, the side wall of the container 9 can be pushed by the second plate-shaped component to adjust the direction of the loader. Of course, the driving component 22 can also adopt other embodiments.

[0095] The above description is only an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
