Description

Technical Field

[0001] The present application relates to the technical field of warehousing systems, and in particular to a two-way cargo box storage and retrieval device, a freight gantry, and a warehousing system. Background Art

[0002] To increase container storage density, modern automated warehousing systems typically design racks in densely packed, high-rise, three-dimensional structures. Storing and retrieving containers from the racks typically requires automated guided vehicles (AGVs) to move containers within the storage area. With the increasing demand for container storage, allocation, and handling within individual shelves and adjacent rack groups within a warehousing system, the efficiency of traditional AGVs is no longer sufficient.

[0003] Installing freight gantries on warehouse racks can improve freight handling efficiency. However, existing gantry access mechanisms are typically only capable of accessing containers stored in the front storage areas facing the aisles on a single shelf. As demand for container storage density continues to increase, warehouse systems are expected to adopt deeper racking designs, such as adding more rear storage areas behind the front storage areas. This necessitates improvements to the container access mechanisms on gantry racks to accommodate deeper container storage and retrieval. Summary of the Invention

[0004] This application is made in view of the above-mentioned state of the prior art. The purpose of this application is to provide a two-way container storage and retrieval device, which can store and retrieve containers on adjacent shelves.

[0005] The present application also provides a freight gantry and a warehousing system including the above-mentioned two-way cargo box storage and retrieval device.

[0006] The present application provides a two-way cargo box access device, which is used to be installed on a freight gantry to move a cargo box. The two-way cargo box access device includes a base frame, a first access portion and a second access portion.

[0007] The first access portion is used to move the cargo box between the chassis and the front storage position of the shelf; the second access portion is used to move the cargo box between the front storage position of the shelf and one or more rear storage positions behind it.

[0008] The first access portion includes a primary container contact portion and a first translation mechanism, wherein the first translation mechanism is directly or indirectly connected to the primary container contact portion, so that the primary container contact portion can move in both directions in the width direction of the bidirectional container access device.

[0009] The primary container contact portion is capable of moving the container to the chassis.

[0010] The second storage and retrieval portion includes a secondary cargo box contact portion and a second translation mechanism, and the second translation mechanism is directly or indirectly connected to the secondary cargo box contact portion, so that the secondary cargo box contact portion can move in both directions in the width direction of the two-way cargo box storage and retrieval device.

[0011] The present application also provides a freight gantry for being arranged on a shelf to transfer cargo boxes, comprising:

[0012] Lifting mechanism; and the aforementioned two-way cargo box access device,

[0013] The lifting mechanism is connected to the two-way cargo box storage and retrieval device, and the lifting mechanism can drive the two-way cargo box storage and retrieval device to move in the height direction of the shelf.

[0014] The present application also provides a warehousing system, comprising a plurality of shelves and the aforementioned freight gantry, wherein the shelves include:

[0015] At least one front storage location facing the aisle,

[0016] Optionally, at least one rear storage location is provided behind the front storage location,

[0017] The freight gantry is provided between opposite surfaces of two adjacent shelves in the width direction and is used to move cargo boxes provided on the two shelves.

[0018] The bidirectional container access device, freight gantry, and storage system provided by the present application can access and move containers on a shelf through a first access portion and a second access portion provided on the container access device. The first access portion of the bidirectional container access device can be used to move a container to or from a bottom shelf; the second access portion can be used to move a container from a storage location at the rear of the shelf to a storage location at the front of the shelf, or vice versa.

[0019] Through the coordinated operation of the first access part and the second access part, cargo boxes at different positions on the shelf can be moved in both directions, supporting the warehousing and outbound operations of goods. In addition, the goods can be converted between the front and rear rows of the shelf, thereby improving the overall adaptability of the storage system.

[0036] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible embodiments of the present application, nor to limit the scope of the present application.

[0037] In this application, to facilitate description of the orientation and relative position of various structures, the directional coordinates in the accompanying drawings are shown, where the X direction represents the width of the container access device 100, the Y direction represents the length of the container access device 100, and the Z direction represents the height of the container access device 100. The above directional description also applies to the orientation of the cargo gantry 200 and the shelf 300.

[0038] In this application, conveyor belts, synchronous belts, chains, and corresponding wheel structures are used only to illustrate preferred embodiments of the present application and do not constitute a limitation on the present application. It is understood that most transmission structure options in this application include, but are not limited to, conveyor belts, synchronous belts, and chains. When understanding the technical solution, the corresponding transmission structure should be understood in a broad sense.

[0039] The embodiment of the present application provides a two-way container storage and retrieval device 100 (hereinafter sometimes referred to as a container storage and retrieval device), such as Figure 1 and Figure 2 As shown, it can be installed on a freight gantry 200 to move cargo boxes 400 placed on a shelf 300. In particular, it can be used to access and move cargo boxes on multiple rows of shelves (also known as multiple storage space shelves or multi-depth shelves, which can have at least two storage spaces arranged side by side). Furthermore, the technical solution provided by this application can also be used to access and move cargo boxes on more rows of shelves.

[0040] As a preferred embodiment, the present application takes double-row shelves (two deep storage locations or a front storage location facing the aisle and a rear storage location arranged behind it) as an example for detailed description.

[0041] like Figure 3 and Figure 4 As shown, the cargo box access device 100 may include a bottom frame 110, a first access portion 120 and a second access portion 130. Figure 7 As shown, the first access portion 120 may include a primary container contact portion 121 and a first translation mechanism 122. The first translation mechanism 122 may be directly or indirectly connected to the primary container contact portion 121, enabling bidirectional movement of the primary container contact portion 121 in the width direction (i.e., the X direction) of the bidirectional container access device. The base frame 110 may be disposed adjacent to the first access portion 120 in the length direction (i.e., the Y direction), enabling the primary container contact portion 121 to move a container to the base frame 110 or to move a container from the base frame 110 to a shelf.

[0042] like Figure 4 and Figure 10 As shown, the second storage and access portion 130 may include a secondary cargo box contact portion 131 and a second translation mechanism. The second translation mechanism may be directly or indirectly connected to the secondary cargo box contact portion 131, so that the secondary cargo box contact portion 131 can move bidirectionally in the width direction of the bidirectional cargo box storage and access device.

[0043] The maximum stroke of the second translation mechanism can be greater than the maximum stroke of the first translation mechanism 122. In particular, the maximum stroke of the second translation mechanism can be twice (including approximately twice) the maximum stroke of the first translation mechanism 122. In some examples, the maximum stroke of the second translation mechanism can be multiple times the maximum stroke of the first translation mechanism 122.

[0044] Specifically, such as Figure 4 and Figure 5As shown, the chassis 110 may include a conveying portion 111 and guide edges 112. The conveying portion 111 enables bidirectional movement of the container along the width of the bidirectional container access device. The guide edges 112 may be provided on both sides of the conveying portion 111 in the longitudinal direction of the bidirectional container access device and extend along the width direction to correct the position and movement direction of the container.

[0045] Furthermore, in this embodiment, if Figure 4 、 Figure 5 and Figure 6 As shown, the conveying portion 111 of the chassis 110 can be a belt conveyor. The belt conveyor can include a conveying drive unit 1111, a transmission shaft 1112, two conveying wheel groups 1113, and two conveyor belts 1114. The two conveyor belts 1114 can be respectively sleeved on the two conveying wheel groups 1113, so that when the conveying wheel groups 1113 rotate, they can drive the conveyor belts 1114 to move. The conveying drive unit 1111 can be connected to the two conveying wheel groups 1113 via the transmission shaft 1112, so that the conveying drive unit 1111 can simultaneously drive the two conveyor belts 1114 to move. The two conveyor belts 1114 and the two conveying wheel groups 1113 can be spaced apart in the length direction of the two-way cargo box storage and retrieval device. The conveying wheel group can include multiple conveying wheels to enhance its load-bearing capacity.

[0046] In another example, the conveying portion 111 may also adopt other conveying structures such as conveying rollers.

[0047] like Figure 7 、 Figure 8 and Figure 9 As shown, the first access portion 120 may include a primary container contact portion 121, a first translation mechanism 122, and a lifting mechanism 123. The lifting mechanism 123 may be connected to the first translation mechanism 122 and may move bidirectionally with the first translation mechanism 122 in the width direction of the bidirectional container access device.

[0048] The primary cargo box contact portion 121 can be directly or indirectly connected to the lifting mechanism 123 and can move with the lifting mechanism 123 in the height direction (i.e., Z direction) of the two-way cargo box storage and retrieval device. The height change of the primary cargo box contact portion 121 can enable the primary cargo box contact portion 121 to avoid the cargo box (in the height direction) when moving in both directions along the width direction. In particular, when transferring goods between shelves adjacent to each other in the width direction, the primary cargo box contact portion 121 hooks the cargo box from the shelf on one side. After the cargo box is on the conveying portion 111, the movement of the first translation mechanism 122 and the lifting mechanism 123 can enable the primary cargo box contact portion 121 to move to one side in the width direction of the cargo box (the opposite side of the hooking side) and push the cargo box into the shelf on the other side.

[0049] Preferably, Figure 7 and Figure 8 As shown, the first access portion 120 may further include a contact portion rotating mechanism 124, and the axial direction of the rotation axis of the contact portion rotating mechanism 124 may be parallel to the length direction of the two-way cargo box access device. The contact portion rotating mechanism 124 may be connected to the lifting mechanism 123 and may move along with the lifting mechanism 123 in the height direction of the two-way cargo box access device. The first-level cargo box contact portion 121 is connected to the contact portion rotating mechanism 124 and may rotate around the rotation axis of the contact portion rotating mechanism 124. By rotating the first-level cargo box contact portion 121, it may be engaged (hooked) with a slot (such as Figure 3 As shown, the upper portion of the cargo box may form a slot opening downward), thereby pulling the cargo box (especially the cargo box arranged at the front storage position) into the chassis 110 (especially the conveying portion 111 thereof).

[0050] The contact portion rotation mechanism 124 may include a rotation motor 1241 and a contact portion connecting rod 1242. One end of the contact portion connecting rod 1242 may be connected to the rotating shaft of the rotation motor 1241, and the other end of the contact portion connecting rod 1242 may be connected to the primary container contact portion 121. The contact portion connecting rod 1242 may also be formed into a bent structure to avoid other structures (such as the distance sensor 127 disposed below the contact portion rotation mechanism 124) during its rotation.

[0051] Specifically, such as Figure 7 、 Figure 8 and Figure 9 As shown, the first translation mechanism 122 may include a translation motor 1221, a translation transmission part 1222, and a translation rail 1223. The translation motor 1221 may be connected to the translation transmission part 1222 to drive the translation transmission part 1222 to move.

[0052] Furthermore, the first access portion 120 may further include a first positioning plate 126 . The first positioning plate 126 may be connected to the base frame 110 . In particular, the first positioning plate 126 may be fixed to the base frame 110 .

[0053] The translation rail 1223 can be mounted on the first positioning plate 126. Both the first positioning plate 126 and the translation rail 1223 can extend along the width of the two-way container storage and retrieval device. The lifting mechanism 123 can be slidably connected to the translation rail 1223. The lifting mechanism 123 is also connected to the translation transmission unit 1222, so that the translation motor 1221 can drive the lifting mechanism 123 to slide along the translation rail 1223.

[0054] In this embodiment, the translation transmission part 1222 can be arranged on the side of the first positioning plate 126 away from the primary cargo box contact part 121, and the translation motor 1221 and the translation slide rail 1223 can be arranged on the side of the first positioning plate 126 close to the primary cargo box contact part 121.

[0055] Preferably, the first translation mechanism 122 is provided with two translation rails 1223 , and the two translation rails 1223 can be staggered in the height direction of the first positioning plate 126 , and the lifting mechanism 123 can be slidingly connected to the two translation rails 1223 respectively to enhance the connection stability of the lifting mechanism 123 .

[0056] Furthermore, in this embodiment, the translation transmission unit 1222 may include a translation sprocket assembly 12221 and a translation chain 12222. The translation motor 1221 may be connected to the translation sprocket assembly 12221, and the translation chain 12222 engages with the translation sprocket assembly 12221, enabling the translation motor 1221 to drive the translation chain 12222. The lifting mechanism 123 may be connected to the translation chain 12222 via a lifting mechanism connection 1224, enabling the translation motor 1221 to drive the lifting mechanism 123 to slide along the translation rail 1223.

[0057] like Figure 8 、 Figure 9 and Figure 10 As shown, the lifting mechanism 123 may include a lifting motor 1231, a lifting transmission unit 1232, a lifting rail 1233, and a lifting base plate 1234. The lifting motor 1231 may be connected to the lifting transmission unit 1232 to drive the lifting transmission unit 1232. The lifting base plate 1234 is connected to the first translation mechanism 122. In particular, the lifting base plate 1234 may be connected to the aforementioned translation rail 1223 and the lifting mechanism connection unit 1224.

[0058] The lifting rail 1233 can extend along the height direction of the two-way container storage and retrieval device, and the lifting rail 1233 is connected to the lifting transmission part 1232, so that the lifting rail 1233 moves with the lifting transmission part 1232. The lifting rail 1233 can also be slidably connected to the lifting base plate 1234.

[0059] Specifically, such as Figure 9 As shown, the lifting transmission unit 1232 may further include a lifting wheel assembly 12321, a lifting synchronous belt 12322, and a base plate connection portion 12323. The lifting motor 1231 is connected to the lifting wheel assembly 12321, and the lifting synchronous belt 12322 is engaged with the lifting wheel assembly 12321. In this embodiment, the lifting wheel assembly 12321 may include two synchronous wheels arranged opposite to each other in the height direction.

[0060] The base plate connection portion 12323 is fixed to the lifting base plate 1234. The lifting timing belt 12322 can be connected to the lifting base plate 1234 via the base plate connection portion 12323. Specifically, the base plate connection portion 12323 and the area of ​​the lifting timing belt 12322 connected thereto can be fixed relative to the lifting base plate 1234. Because one portion of the lifting timing belt 12322 is fixed relative to the lifting base plate 1234, when the lifting wheel assembly 12321 rotates, the distance between the timing wheels and the fixed portion of the lifting timing belt 12322 changes, enabling the lifting motor 1231 to drive the lifting transmission portion 1232 to move relative to the lifting base plate 1234 in the height direction of the two-way container storage and retrieval device.

[0061] Preferably, the outer end surface of the primary container contact portion 121 in the direction in which the contact portion connecting rod 1242 extends can be a flat surface, which is used to push the container in the width direction of the two-way container storage and retrieval device away from the base frame 110. The inner side surface of the primary container contact portion 121 in the direction in which the contact portion connecting rod 1242 extends can be formed into a curved surface or an inclined surface, which is used to engage with the container's slot.

[0062] Further, such as Figure 4 、 Figure 10 、 Figure 11 and Figure 12 As shown, the second translation mechanism of the second access portion 130 may include a driving portion 132, a primary translation mechanism 133, and a secondary translation mechanism 134. The secondary translation mechanism 134 is driven to move by a driving mechanism via the primary translation mechanism 133. The driving portion 132 may be directly or indirectly connected to the primary translation mechanism 133 to drive the primary translation mechanism 133 to move. The secondary translation mechanism 134 is directly or indirectly linked to the primary translation mechanism 133 so that the secondary translation mechanism 134 moves synchronously with the primary translation mechanism 133, and the stroke of the secondary translation mechanism 134 is greater than that of the primary translation mechanism 133. The movement distance of the secondary translation mechanism 134 may be a multiple of the movement distance of the primary translation mechanism 133, in particular, twice (including approximately twice).

[0063] The drive unit 132 may include a drive motor 1321 and a drive transmission unit 1322. The primary translation mechanism 133 may include a primary synchronous wheel set 1331 and a primary synchronous belt 1332. The drive motor 1321 may be connected to the primary synchronous wheel set 1331 via the drive transmission unit 1322. The primary synchronous belt 1332 is mounted on the primary synchronous wheel set 1331, enabling the drive motor 1321 to drive the primary synchronous belt 1332 to move.

[0064] The secondary translation mechanism 134 may include a linkage portion 1341, a first pulley 1342, a second pulley 1343, a first transmission belt 1344, and a second transmission belt 1345. The linkage portion 1341 may be connected to the primary translation mechanism 133 and may move therewith. In particular, the linkage portion 1341 may be connected to the primary timing belt 1332. At least a portion of the outer surface of the primary timing belt 1332 may form an engaging structure, and the lower portion of the linkage plate may at least partially engage with the primary timing belt 1332, enabling the primary translation mechanism 133 to drive the linkage portion 1341 to move along the width direction of the bidirectional container storage and retrieval apparatus.

[0065] The axles of the first pulley 1342 and the second pulley 1343 can be connected to the linkage portion 1341, so that the first pulley 1342 and the second pulley 1343 can move with the linkage portion 1341. Exemplarily, the rotation axis directions of the first pulley 1342 and the second pulley 1343 can be parallel to the height direction.

[0066] The first pulley 1342 and the second pulley 1343 may be respectively disposed on both sides of the linkage portion 1341 in the width direction of the bidirectional container storage and retrieval device, and the first pulley 1342 and the second pulley 1343 may be staggered in the height direction.

[0067] like Figure 12 and Figure 13 As shown, one end of a first transmission belt 1344 is fixed relative to the base frame 110, a portion of the first transmission belt 1344 is wound around a first pulley 1342, and the other end of the first transmission belt 1344 is connected to the secondary container contact portion 131. One end of a second transmission belt 1345 is fixed relative to the base frame 110, a portion of the second transmission belt 1345 is wound around a second pulley 1343, and the other end of the second transmission belt 1345 is connected to the secondary container contact portion 131. Because the first pulley 1342 and the second pulley 1343 are respectively arranged on opposite sides in the width direction, the curved opening directions of the first transmission belt 1344 and the second transmission belt 1345 can be opposite.

[0068] When the secondary translation mechanism 134 is in the initial position (i.e., when the second access part has not moved to the outside in the width direction of the cargo box access device), the lengths of the parts of the first transmission belt 1344 located on both sides of the first pulley 1342 can be equal, and the lengths of the parts of the second transmission belt 1345 located on both sides of the second pulley 1343 can also be equal.

[0069] When the primary translation mechanism 133 drives the linkage part 1341 to move, since one end of the first transmission belt 1344 and the second transmission belt 1345 are fixed relative to the base frame 110, when the linkage part 1341 moves, the length of the transmission belts on both sides of the first pulley 1342 and the second pulley 1343 will change accordingly, that is, the transmission belt will drive the secondary cargo box contact part 131 to move horizontally (that is, along the width direction).

[0070] For example, Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the sides of the first and second transmission belts 1344 and 1345, which are away from the primary container contact portion 121, are both fixed relative to the base frame 110. When the linkage portion 1341 moves away from the direction indicated by the coordinate arrow X, the length of the side of the first transmission belt 1344 near the primary container contact portion 121 decreases, pulling the secondary container contact portion 131 in the direction away from the coordinate arrow X. When the linkage portion 1341 moves in the direction indicated by the coordinate arrow X, the length of the side of the second transmission belt 1345 near the primary container contact portion 121 decreases, pulling the secondary container contact portion 131 in the direction indicated by the coordinate arrow X.

[0071] It is understood that during the movement of the secondary translation mechanism, the first pulley 1342 and the second pulley 1343 function similarly to movable pulleys, and the movement length of the first transmission belt 1344 and the second transmission belt 1345 is twice the movement length of the first pulley 1342 and the second pulley 1343 (i.e., the movement length of the linkage). In other words, the secondary translation mechanism can amplify the movement distance of the primary translation mechanism by two times in both directions in the width direction, thereby enabling access to the rear storage location. It is understood that, based on the above structure, further structures such as a movable pulley assembly can be provided to further amplify the movement distance of the primary translation mechanism, enabling access to multiple storage locations.

[0072] Preferably, the second storage and retrieval portion 130 may further include a second positioning plate 135, which may extend along the width and height of the bidirectional container storage and retrieval device. The second positioning plate 135 is connected to the base frame 110. One end of the first transmission belt 1344 and one end of the second transmission belt 1345 are both connected to the second positioning plate 135, thereby indirectly securing the primary translation mechanism 133 to the base frame 110. At least a portion of the primary translation mechanism 133 may be connected to the second positioning plate 135. For example, the primary synchronous wheel assembly 1331 of the primary translation mechanism 133 may be disposed on the second positioning plate 135.

[0073] Preferably, the linkage portion 1341 may be a linkage plate, which extends along the width direction and the height direction of the two-way cargo box storage and retrieval device, so that the linkage plate is arranged parallel to the second positioning plate 135 .

[0074] The secondary container contact portion 131 may include a first contact portion 1311, a second contact portion 1312, and a contact portion connecting plate 1313. The contact portion connecting plate 1313 may extend along the width and height of the two-way container access device. The other ends of the first transmission belt 1344 and the second transmission belt 1345 are both connected to the contact portion connecting plate 1313, enabling the transmission belts to drive the secondary container contact portion 131.

[0075] The first contact portion 1311 and the second contact portion 1312 may be respectively provided at both ends of the contact portion connecting plate 1313 in the width direction of the bidirectional container access device.
