[0039] Reference Figures 1 to 7 As shown, one embodiment of the present invention provides a cage loading device, which includes a base plate 2, a lifting assembly 3 and a tilting assembly 4.

[0040] The base plate 2 is used to be installed on the unmanned transport vehicle to carry the cage 7 inside the carriage 1. The lifting assembly 3 is located on the side of the base plate 2. The lifting assembly 3 includes a first guide rail 31 and a lifting part 32 disposed on the first guide rail 31. The lifting part 32 can be controlled to move along the first guide rail 31 to change its height. The tilting assembly 4 is disposed on the lifting part 32 and can move up and down synchronously with the lifting part 32. The tilting assembly 4 includes a tilting shaft 41 and a tilting part 42 connected to the tilting shaft 41. The tilting part 42 can be controlled to tilt around the tilting shaft 41.

[0041] According to the above structural design, the lifting part 32 and the tilting part 42 have a first working state and a second working state that cooperate with each other.

[0042] In the first working state, the lifting part 32 and the tilting part 42 are both lowered to a position lower than the bottom plate 2. The tilting part 42 has a preset angle relative to the lifting part 32 and is approximately parallel to the horizontal plane. The cage 7 can be placed on the tilting part 42 and the tilting part 42 can support the cage 7 from the bottom.

[0043] In the second working state, the lifting part 32 drives the cage 7 to rise. When the cage 7 is raised to a position higher than the bottom plate 2, the tilting part 42 rotates around the tilting shaft 41 toward the inside of the carriage 1 and drives the cage 7 to rotate synchronously with it. When the tilting part 42 rotates to approximately perpendicular to the horizontal plane, the cage 7 contacts the bottom plate 2. At this time, the bottom plate 2 can support the cage 7 and complete the loading of the cage 7.

[0044] The following is a further introduction to the lifting component 3.

[0045] In one embodiment, reference is made to Figures 5 to 7 As shown, the lifting unit 32 includes a first side plate, a second side plate, and a third side plate. The first side plate and the second side plate are arranged opposite each other in the horizontal direction and are located on both sides of the first guide rail 31, respectively. The third side plate connects the first side plate and the second side plate.

[0046] The first guide rail 31 extends roughly in a vertical direction. The first guide rail 31 has a first guide groove 311 on both sides facing the first side plate and the second side plate. The first side plate and the side of the second side plate facing the first guide rail 31 are provided with a first roller 33 that cooperates with the first guide groove 311. The rotation axis of the first roller 33 is parallel to the groove opening direction of the first guide groove 311.

[0047] When the lifting part 32 moves along the first guide rail 31, the first roller 33 contacts the lateral groove wall of the first guide groove 311 and rolls along the groove wall, reducing the friction between the lifting part 32 and the first guide rail 31 and reducing the resistance of the lifting part 32.

[0048] In one embodiment, the lifting assembly 3 further includes a lifting transmission mechanism connected to the lifting part 32. The lifting transmission mechanism includes, but is not limited to, a chain transmission mechanism, a screw transmission mechanism, a gear and rack transmission mechanism, a lead screw and nut transmission mechanism, a hydraulic / pneumatic lifting transmission mechanism, a scissor-type lifting transmission mechanism, and an electromagnetic lifting transmission mechanism. Any transmission mechanism that can change the height of the lifting part 32 can be used as a lifting transmission mechanism.

[0049] Optionally, the lifting transmission mechanism is a chain transmission mechanism, which includes two sprockets with a height difference and a chain that drives the two sprockets. A certain part of the chain is fixedly connected to the lifting part 32, so that the lifting part 32 can drive the lifting part 32 to rise and fall synchronously with it.

[0050] In one embodiment, reference is made to Figure 5 As shown, there are two first guide rails 31, two lifting parts 32 and two lifting transmission mechanisms. The two first guide rails 31 are arranged in a horizontal direction, and the two first guide rails 31, the two lifting parts 32 and the two lifting transmission mechanisms cooperate with each other in a one-to-one correspondence.

[0051] Furthermore, the lifting assembly 3 also includes a first drive shaft 34, which is connected to two lifting transmission mechanisms. This allows power to be transmitted to both lifting transmission mechanisms simultaneously, saving the number of drive components and enabling the synchronous lifting of the two lifting parts 32.

[0052] It should be noted that the transmission method of the first drive shaft 34 needs to be adapted to the specific structure of the lifting transmission mechanism. As an example, when a chain drive mechanism is selected for the lifting transmission mechanism, the first drive shaft 34 needs to be connected to the shafts of the two sprockets to transmit torque.

[0053] The following is a further introduction to the flip component 4.

[0054] In one embodiment, reference is made to Figure 7 As shown, the flipping part 42 includes a bearing surface 423 for bearing the cage 7. The bearing surface 423 is provided with a first limiting part 43 and a second limiting part 44. The first limiting part 43 and the second limiting part 44 are arranged at intervals along the extension direction of the flipping part 42. The first limiting part 43 and the second limiting part 44 form a limiting space adapted to the size of the cage 7. The limiting space restricts the movement of the cage 7 along the extension direction of the flipping part 42.

[0055] In one embodiment, reference is made to Figure 7 As shown, the tilting part 42 includes a supporting section 421 and a limiting section 422. The ends of the limiting section 422 and the supporting section 421 away from the lifting part 32 are respectively located on both sides of the tilting shaft 41. The supporting section 421 is used to support the cage 7. The tilting assembly 4 also includes a third limiting part 45 fixedly connected to the lifting part 32. When the tilting part 42 is in the first working state, the third limiting part 45 abuts against the top of the limiting section 422. When the transmission structure of the tilting assembly 4 fails, a lever structure can be formed between the tilting part 42, the cage 7 and the third limiting part 45, providing a certain force to the tilting part 42 so that the tilting part 42 can stably support the cage 7 and prevent the cage 7 from slipping or tipping over.

[0056] In one embodiment, reference is made to Figure 5 As shown, there are two flipping components 4, and the two flipping components 4 are connected to the two lifting parts 32 in a one-to-one correspondence.

[0057] Furthermore, the flipping part 42 of the flipping assembly 4 is constructed as a long strip structure extending along a straight line, and its structure is similar to the fork arm of a forklift.

[0058] In one embodiment, the flipping assembly 4 further includes a flipping transmission mechanism connected to the flipping part 42. The flipping transmission mechanism includes, but is not limited to, a chain transmission mechanism, a belt transmission mechanism, a gear transmission mechanism, and a linkage transmission mechanism. Any transmission mechanism that can drive the flipping shaft 41 to rotate can be used as the flipping transmission mechanism.

[0059] Optionally, the reversing transmission mechanism is a chain transmission mechanism, which includes a driving sprocket, a driven sprocket, and a chain. The driving sprocket is connected to a drive element (e.g., a motor), the driven sprocket is connected to the reversing shaft 41, and the chain is in transmission cooperation with the driving sprocket and the driven sprocket.

[0060] The cage loading device in the above embodiments is relatively suitable for unmanned transport vehicles with a short carriage 1. The carriage 1 of such unmanned transport vehicles has a limited capacity and can mostly only accommodate one cage 7. Therefore, after the cage loading device transfers the cage 7 into the carriage 1, it is not necessary to move the cage 7, or it is only necessary to push the cage 7 a short distance away from the cage loading device. Therefore, there is no need to install a component for moving the cage 7 on the base plate 2.

[0061] For unmanned transport vehicles with a long carriage 1, the capacity of the carriage 1 is relatively large, often accommodating two or more cage boxes 7. In this case, how to move the cage boxes 7 within the carriage 1 has become a key issue affecting the loading efficiency of the cage boxes 7.

[0062] To address the above problems, in one embodiment, reference is made to... Figures 3 to 8 As shown, the cage loading device also includes a translation component 5 located on the top of the bottom plate 2. The translation component 5 includes a controllable translation part 51, which can be used to carry the cage 7.

[0063] When the translation part 51 is in the first working position, it is relatively close to the flipping component 4. At this time, the flipping component 4 can flip the cage 7 it carries to the top of the translation part 51.

[0064] After the cage 7 is transferred to the top of the translation section 51, the translation section 51 moves to the second working position in a direction away from the tilting component 4. The cage 7 moves to the second working position along with the translation section 51, leaving space inside the carriage 1 near the tilting component 4 to accommodate another cage 7.

[0065] In one embodiment, reference is made to Figure 4 , Figure 5 and Figure 8 As shown, when the lifting assembly 3 and the tilting assembly 4 are installed at the rear of the carriage 1, the translation part 51 moves along the front-rear direction of the carriage 1, and the direction of movement of the translation part 51 is perpendicular to the axial direction of the tilting shaft 41.

[0066] In one embodiment, reference is made to Figure 8 and Figure 9 As shown, the translation component 5 includes two second guide rails 52 and multiple second rollers 53. The two second guide rails 52 are arranged opposite to each other and both extend along the moving direction of the translation part 51. The multiple second rollers 53 are respectively arranged on opposite sides of the two second guide rails 52. The translation part 51 is located between the two second guide rails 52, and each side of the translation part 51 facing the second guide rails 52 has a second guide groove 511 that cooperates with the second rollers 53.

[0067] When the translation part 51 moves along the second guide rail 52, the second roller 53 contacts the top or bottom wall of the second guide groove 511 and rolls along the groove wall, reducing the friction between the translation part 51 and the second guide rail 52 and reducing the resistance of the translation part 51.

[0068] In one embodiment, the translation component 5 further includes a translation transmission mechanism connected to the translation part 51. The translation transmission mechanism includes, but is not limited to, a chain transmission mechanism, a belt transmission mechanism, a gear transmission mechanism, and a linkage transmission mechanism. Any transmission mechanism that can drive the translation part 51 to move can be used as a translation transmission mechanism.

[0069] Optionally, the translation transmission mechanism is a chain transmission mechanism, which includes a driving sprocket, a driven sprocket, and a chain that drives and cooperates with the driving sprocket and the driven sprocket. The driving sprocket is connected to a drive element (e.g., a motor), and a certain part of the chain is fixedly connected to the translation part 51, so that the chain part can drive the translation part 51 to move synchronously with it.

[0070] Although the translation component 5 in the above embodiments can move the cage 7 in the long carriage 1, its translation part 51 is difficult to separate from the cage 7 after it comes into contact with the cage 7, so it is impossible to transfer the cage 7 loaded later.

[0071] To address the above problems, in one embodiment, reference is made to... Figure 8 , Figure 10 and Figure 11 As shown, the cage loading device also includes a lifting assembly 6 disposed on the translation section 51. The lifting assembly 6 includes a lifting section 61 that can be controlled to move in a vertical direction. The lifting section 61 can controllably drive the cage 7 on the translation section 51 to move up and down.

[0072] For cage 7 without bottom supports, both bottom plate 2 and second guide rail 52 can serve as load-bearing structures to contact the bottom surface of cage 7 to support it. Lifting part 61 and load-bearing structure should meet the following conditions: When lifting part 61 is at its highest point, its top surface should be higher than the contact surface on the load-bearing structure used to contact cage 7, and the bottom surface of cage 7 should not contact the load-bearing structure to avoid mutual interference and affect the translation of lifting part 61 following translation part 51; When lifting part 61 is at its lowest point, its top surface should be lower than the contact surface on the load-bearing structure used to contact cage 7, so that the bottom surface of cage 7 can be separated from the top surface of lifting part 61, and cage 7 and lifting part 61 can be separated from each other.

[0073] For a cage 7 with legs at the bottom, the bottom plate 2 generally acts as a load-bearing structure and contacts the legs of the cage 7 to support the cage 7. The lifting part 61 and the load-bearing structure should meet the following conditions: when the lifting part 61 is at its highest point, the legs of the cage 7 do not contact the load-bearing structure to avoid interference between the two and affect the translation of the lifting part 61 following the translation part 51; when the lifting part 61 is at its lowest point, the legs of the cage 7 can contact the load-bearing structure, and the top surface of the lifting part 61 is lower than the bottom surface of the cage 7, so that the cage 7 and the lifting part 61 are separated from each other.

[0074] According to the above structural design, when the translation part 51 is in the first working position, the lifting part 61 rises to its highest point, and the flipping part 42 cooperates with the lifting part 32 in the second working state. At this time, the flipping assembly 4 can transfer the cage 7 onto the lifting part 61. Then, the translation part 51 moves to the second working position, and the lifting part 61 descends to its lowest point and separates from the cage 7, placing the cage 7 on the base plate 2 and the second guide rail 52. After the translation part 51 returns to the first working position, it can continue to transfer the next cage 7.

[0075] In one embodiment, the lifting assembly 6 further includes a lifting transmission mechanism that drives the lifting section 61 to move up and down. The lifting transmission mechanism includes, but is not limited to, screw transmission mechanism, chain transmission mechanism, gear and rack transmission mechanism, lead screw and nut transmission mechanism, hydraulic / pneumatic lifting transmission mechanism, scissor lift transmission mechanism and electromagnetic lifting transmission mechanism. Any transmission mechanism that can change the height of the lifting section 61 can be used as a lifting transmission mechanism.

[0076] In one embodiment, reference is made to Figure 11 As shown, the lifting section 61 includes a first lifting section 611 and a second lifting section 612, which are arranged along the moving direction of the translation section 51.

[0077] Furthermore, the lifting assembly 6 also includes a first lifting transmission mechanism 64, a second lifting transmission mechanism 65, and a second drive shaft 62. The first lifting transmission mechanism 64 drives the first lifting part 611 to move up and down, and the second lifting transmission mechanism 65 drives the second lifting part 612 to move up and down. The second drive shaft 62 is connected to the first lifting transmission mechanism 64 and the second lifting transmission mechanism 65, which can transmit power to the first lifting transmission mechanism 64 and the second lifting transmission mechanism 65 at the same time, saving the number of driving components and realizing the synchronous lifting of the two lifting parts 61.

[0078] It should be noted that the transmission method of the second drive shaft 62 needs to be adapted according to the specific structure of the first lifting transmission mechanism 64 and the second lifting transmission mechanism 65. As an example, when the first lifting transmission mechanism 64 and the second lifting transmission mechanism 65 are selected as screw transmission mechanisms, the second drive shaft 62 needs to be connected to the two corresponding screws of the first lifting transmission mechanism 64 and the second lifting transmission mechanism 65, and the torque is transmitted between the two screws through the second drive shaft 62.

[0079] In one embodiment, reference is made to Figure 11 As shown, multiple first lifting transmission mechanisms 64, second lifting transmission mechanisms 65, and second transmission shafts 62 are provided in a one-to-one correspondence. Multiple second transmission shafts 62 are connected by a synchronous transmission mechanism 65, which includes, but is not limited to, chain transmission mechanism and gear transmission mechanism.

[0080] As an example, when the synchronous drive mechanism 65 is a chain drive mechanism, a sprocket is installed on each second drive shaft 62, and torque is transmitted between the sprockets through a chain.

[0081] In one embodiment, reference is made to Figures 1 to 3 As shown, this utility model also provides an unmanned transport vehicle, which includes a carriage 1 and the aforementioned cage loading device, with the cage loading device installed at the rear of the carriage 1.

[0082] In other embodiments, the cage loading device may also be installed on the side of the carriage 1.

[0083] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this 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 this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0084] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification 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.
