Detailed implementation manners

[0076] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementations disclosed below.

[0077] The present application provides an automated system for storing and retrieving goods, a three-dimensional storage rack, and a goods warehousing method. The following describes an automated system for storing and retrieving goods, a three-dimensional storage rack, and a goods warehousing method of the present application using specific embodiments. It should be noted that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0078] The first embodiment of the present application provides an automated system for accessing goods, so as to improve the utilization rate of warehouse space and reduce the cost of accessing goods.

[0079] Combined with Figure 1 As shown, an automated system 100 for accessing goods provided by the first embodiment of the present application includes: an inbound conveying device 10, a stacker 1, a three-dimensional shelf 2, and an outbound conveying device 30. The inbound conveying device 10 includes a first traveling device 20.

[0080] Among them, the first traveling device 20 is connected to the inbound distribution end of the three-dimensional shelf 2 to transport the goods carried by the inbound conveying device 10 to the inbound distribution end of the three-dimensional shelf 2 through the first traveling device 20. In the first embodiment of the present application, the goods to be transported can be the main beam or auxiliary beam of an automobile frame; of course, the goods to be transported can also be other products, and the first embodiment of the present application does not make specific limitations on this.

[0081] In the first embodiment of the present application, the inbound conveying device 10 mainly transports the processed and formed goods to the inbound distribution end of the three-dimensional shelf 2, or can also process the semi-finished goods during transportation to transport the obtained formed goods to the inbound distribution end of the three-dimensional shelf 2.

[0082] In the first embodiment of the present application, this solution can be described according to the equipment involved in the transportation line of the goods. Specifically, the inbound conveying device 10 includes at least one fourth conveying line 11 and at least one powder spraying line 12, and the fourth conveying line 11 and the powder spraying line 12 are connected. Among them, the powder spraying line 12 is a production line for processing and producing goods, that is, after the goods are processed and formed, they need to enter the powder spraying line 12 for painting to meet the production requirements. The powder spraying line 12 is connected to the main production line for processing goods. After the painting is completed, the goods can be transported to the first traveling device 20 through the fourth conveying line 11, and then transported to the inbound distribution end of the three-dimensional shelf 2 through the first traveling device 20. In the first embodiment of the present application, two powder spraying lines 12 and two fourth conveying lines 11 can be provided, and each powder spraying line 12 is connected to each fourth conveying line 11. And combined with Figure 1 As shown, the two powder spraying lines 12 and the two fourth conveying lines 11 are arranged in the left-right direction, and the two powder spraying lines 12 are arranged in parallel, and the two fourth conveying lines 11 are arranged in parallel.

[0083] After the goods are transported to the first traveling device 20 through the fourth conveying line 11, they are then transported to the inbound distribution end of the three-dimensional shelf 2 through the first traveling device 20. Among them, as Figure 2As shown in the figure, the first transfer device 20 includes a chain transfer machine. The chain transfer machine includes a plurality of sprockets 21 and a plurality of chains 22. Each chain 22 correspondingly wraps two sprockets 21, and the plurality of chains 22 are arranged side by side in the left-right direction. Goods are placed on the chains 22, and the sprockets 21 drive the chains 22 to rotate, so as to drive the goods thereon to move in the up-down direction. Combined with Figure 1 As shown in the figure, since the number of the set fourth conveyor lines 11 is two, in order to transport the goods on both fourth conveyor lines 11 through the first transfer device 20, it is defined that the first transfer device 20 includes an input end and an output end. The input end of the first transfer device 20 is connected to one of the fourth conveyor lines 11, and the output end of the first transfer device 20 is connected to the goods receiving distribution end of the three-dimensional shelf 2. The output end of the other fourth conveyor line 11 can directly transport the goods to the first transfer device 20.

[0084] In the first embodiment of the present application, when the goods are transported to the goods receiving distribution end of the three-dimensional shelf 2, it is necessary to identify and distinguish the goods, so as to transport different goods to the three-dimensional shelf 2 according to different goods receiving distribution ends, which is convenient for reasonable classification storage of the goods. That is, after different goods are classified through different goods receiving distribution ends, they are correspondingly transported to the corresponding areas of the three-dimensional shelf 2.

[0085] Specifically, in the first embodiment of the present application, the goods receiving distribution end of the three-dimensional shelf 2 includes a first goods receiving distribution end 4 and a second goods receiving distribution end 5. And in the vertical direction (in three-dimensional space), the first goods receiving distribution end 4 is arranged below the second goods receiving distribution end 5. Generally speaking, the first goods receiving distribution end 4 is arranged at a lower position, and the second goods receiving distribution end 5 is arranged at a higher position. Among them, the first goods receiving distribution end 4 is used to distribute and transport the first goods, and the second goods receiving distribution end 5 is used to distribute and transport the second goods. In the first embodiment of the present application, if the goods to be transported correspond to the main beam or auxiliary beam of the vehicle frame, then the first goods are the bent beams among the main beam or auxiliary beam, simply referred to as bent beams; the second goods are the straight beams among the main beam or auxiliary beam, simply referred to as straight beams.

[0086] It should be noted that, in the first embodiment of the present application, in order to identify whether the goods are the first goods or the second goods, a goods identification unit 13 is provided at the fourth conveyor line 11 or the second goods receiving distribution end 5. The goods identification unit 13 is used to identify the identification code set on the goods and determine whether the goods are the first goods or the second goods. It should also be noted that, in the first embodiment of the present application, when the goods pass through the second goods receiving distribution end 5, the shapes of the goods can all be straight beams, that is, all the second goods, and then through the bent beam processing equipment arranged between the first goods receiving distribution end 4 and the second goods receiving distribution end 5, the straight beams are processed into bent beams, that is, the second goods are processed into the first goods, and then the first goods are transported to the first goods receiving distribution end 4.

[0087] Specifically, in the first embodiment of the present application, the incoming goods distribution end further includes a second transfer device 6 and a distribution lane position 7. Among them, the first incoming goods distribution end 4 and the second incoming goods distribution end 5 are respectively connected to the distribution lane position 7 through the second transfer device 6 to cooperate with the distribution lane position 7 to achieve the distribution of goods. Specifically, based on the fact that the first incoming goods distribution end 4 and the second incoming goods distribution end 5 are arranged in a hierarchical manner, two second transfer devices 6 can be set, that is, a high-position second transfer device 61 and a low-position second transfer device 62 are included. And the distribution lane position 7 can also be set as a hierarchical structure, that is, a low-position distribution lane corresponding to the first incoming goods distribution end 4 and a high-position distribution lane corresponding to the second incoming goods distribution end 5. Specifically, the low-position second transfer device 62, the first incoming goods distribution end 4 and the low-position distribution lane are arranged at the same plane height, and the low-position second transfer device 62 is arranged between the first incoming goods distribution end 4 and the low-position distribution lane. The high-position second transfer device 61, the second incoming goods distribution end 5 and the high-position distribution lane are arranged at the same plane height, and the high-position second transfer device 61 is arranged between the second incoming goods distribution end 5 and the high-position distribution lane.

[0088] Among them, based on the fact that the specific structures of the high-position second transfer device 61 and the low-position second transfer device 62 are the same as those of the above-mentioned first transfer device 20, no repetitive description will be made here. It should be noted that since the first goods need to be transferred and transported through the second incoming goods distribution end 5 and the high-position second transfer device 61 to reach the first incoming goods distribution end 4, the high-position second transfer device 61 not only has the function of directly transporting the second goods to the high-position distribution lane, but also has the function of transferring and transporting the first goods or the second goods that need to be processed into the first goods, and then can realize the diversion and classification of the goods at the second incoming goods distribution end 5.

[0089] Furthermore, in order to realize the processing of the second goods into the first goods and then transport the first goods to the first incoming goods distribution end 4, the inbound conveying device 10 further includes a first preparation device 8 and a first conveying line 40. Among them, the input end of the first preparation device 8 is arranged close to the high-position second transfer device 61 and is used to prepare the second goods transported by the high-position second transfer device 61 into the first goods. The first conveying line 40 is arranged between the first preparation device 8 and the second incoming goods distribution end 5 and is used to transport the first goods prepared by the first preparation device 8 to the second incoming goods distribution end 5. In the first embodiment of the present application, as Figure 3 shown, the first preparation device 8 includes at least one conveyor belt 81 and bending devices 82 arranged on both sides of at least one conveyor belt 81. The conveyor belt 81 transports the second goods, and after being processed by the bending devices 82, the first goods can be formed. Since the first preparation device 8 is not the focus of the present application, its specific structure will not be specifically described here. As long as it is a device structure that can process a straight beam into a bent beam, it is within the scope protected by the first embodiment of the present application.

[0090] Further, in the process of transporting the first goods prepared by the first preparation device 8 to the first conveyor line 40, combined with Figure 1 As shown, considering the distribution positions of various devices in the entire system, in order to improve the transportation efficiency of the first goods and the second goods, and to rationally utilize the working space, the warehousing conveyor device 10 further includes a third transfer device 50. The third transfer device 50 is arranged between the output end of the first preparation device 8 and the input end of the first conveyor line 40 to transport the first goods prepared by the first preparation device 8 to the first conveyor line 40. And based on the specific structure of the third transfer device 50 being the same as that of the above-mentioned first transfer device 20, no repetitive description will be made here.

[0091] Furthermore, in order to improve the efficiency of processing the second goods into the first goods, the warehousing conveyor device 10 further includes a second conveyor line 60, a third conveyor line 70, and a second preparation device 9. Among them, the second conveyor line 60 is arranged between the first goods receiving distribution end 4 and the input end of the second preparation device 9. The second conveyor line 60 can directly transport the goods determined to be made into the first goods at the position of the first goods receiving distribution end 4 to the second preparation device 9, that is, the second conveyor line 60 transports the second goods to the second preparation device 9 for preparation to form the first goods. The third conveyor line 70 is arranged between the output end of the second preparation device 9 and the third transfer device 50, and transports the first goods prepared by the second preparation device 9 to the third transfer device 50 through the third conveyor line 70. Based on the structure of the second preparation device 9 being the same as that of the above-mentioned first preparation device 8, no repetitive description will be made here.

[0092] Similarly, considering the distribution positions of various devices in the entire system, in order to improve the transportation efficiency of the first goods and the second goods, and to rationally utilize the working space, the warehousing conveyor device 10 further includes a fourth transfer device 80 and a fifth transfer device 90. Among them, the fourth transfer device 80 is arranged between the output end of the second conveyor line 60 and the input end of the second preparation device 9, and is used to transport the second goods transported by the second conveyor line 60 to the second preparation device 9. The fifth transfer device 90 is arranged between the output end of the second preparation device 9 and the input end of the third conveyor line 70, and is used to transport the first goods prepared by the second preparation device 9 to the third conveyor line 70. And based on the specific structures of the fourth transfer device 80 and the fifth transfer device 90 being the same as that of the above-mentioned first transfer device 20, no repetitive description will be made here.

[0093] It can be understood that the goods entering at the second goods distribution end 5 can directly be the first processed goods, and the first goods can also be transported through the above-mentioned device to reach the first goods distribution end 4. It's just that when passing through the first preparation device 8 or the second preparation device 9, the bending device 82 on the first preparation device 8 or the second preparation device 9 stops working, that is, only the conveyor belt 81 on the first preparation device 8 or the second preparation device 9 rotates for transportation to directly transport the processed first goods.

[0094] The above is the specific process of the first goods and the second goods respectively reaching the first goods distribution end 4 and the second goods distribution end 5. Then, in order to store the above goods reasonably, the distribution lane position 7 is misaligned and docked with the lane 34 of the three-dimensional shelf 2. The first goods distribution end 4 and the second goods distribution end 5 are respectively connected to the distribution lane position 7 through the second transfer device 6 to cooperate with the distribution lane position 7 to achieve the distribution of goods.

[0095] Specifically, the reason for the misaligned docking of the distribution lane position 7 and the lane 34 of the three-dimensional shelf 2 is that the stacker 1 moves in the lane 34 of the three-dimensional shelf 2, and the telescopic direction of the fork 103 of the stacker 1 is perpendicular to the extension direction of the lane 34. In order to fork the goods onto the fork 103, it is necessary to provide position space for both the stacker 1 and the fork 103 of the stacker 1, that is, to provide the distribution lane 71 between the distribution lane positions 7. The distribution lane 71 is in the same straight line as the lane 34 of the three-dimensional shelf 2, which allows the stacker 1 to directly drive into the distribution lane position 7, and then the fork 103 can receive the goods on the distribution lane positions 7 on both sides of the stacker 1 and finally transport the goods to the storage location 3 of the three-dimensional shelf 2.

[0096] Among them, in the first embodiment of the present application, corresponding to the foregoing, the low-position second transfer device 62 is arranged between the first goods distribution end 4 and the low-position distribution lane position, and the high-position second transfer device 61 is arranged between the second goods distribution end 5 and the high-position distribution lane position. Therefore, the goods are transported to the goods distribution end of the three-dimensional shelf 2 through the first transfer device 20. Specifically: after the first transfer device 20 transports the goods to the second goods distribution end 5 and identifies and determines that the goods are the second goods, the high-position second transfer device 61 transports the second goods to the high-position distribution lane position; and after the first transfer device 20 transports the goods to the second goods distribution end 5 and identifies and determines that the goods are the first goods, the high-position second transfer device 61 transports the first goods to the first goods distribution end 4 and transports it to the low-position distribution lane position through the low-position second transfer device 62. Then the stacker 1 directly drives into the corresponding distribution lane position 7 and receives the goods on the distribution lane positions 7 on both sides of the stacker 1 through the fork 103, and finally transports the goods to the storage location 3 of the three-dimensional shelf 2.

[0097] Among them, in the first embodiment of the present application, between the aisle 34 of the three-dimensional storage rack 2 and the distribution aisle position, a high-level inbound roller track 72 and a low-level inbound roller track (not shown) are further provided. Specifically, the high-level inbound roller track 72 is docked with the high-level distribution aisle position for transporting the second goods distributed by the high-level distribution aisle position; the low-level inbound roller track is docked with the low-level distribution aisle position for transporting the first goods distributed by the low-level distribution aisle position.

[0098] The structures and working principles of the three-dimensional storage rack 2 and the stacker crane 1 will be described below.

[0099] Specifically, the stacker crane 1 is movably arranged between the aisles 34 of the three-dimensional storage rack 2, and is used to receive the goods at the inbound distribution end, transport the goods to the storage positions 3 with at least two levels of loading platforms symmetrically arranged with the aisle 34 as the center in the three-dimensional storage rack 2, and take out the goods from the storage position 3 to the outbound distribution end of the three-dimensional storage rack 2. Since the specific structure of the stacker crane 1 is not the focus of the present application, it will not be described repeatedly here. However, it should be noted that in the first embodiment of the present application, as Figure 4 shown, the stacker crane 1 includes a moving device 101, a lifting platform 102, and a forklift 103 arranged on the lifting platform 102. The moving device 101 can be matched with the guide rails arranged on the aisle 34 to drive the stacker crane 1 to move between the aisle 34 of the three-dimensional storage rack 2 and the distribution aisle 71. The lifting platform 102 can be lifted in the vertical direction to drive the forklift 103 to lift to the storage positions 3 at different heights in the three-dimensional storage rack 2. The forklift 103 can extend and retract in the two side directions of the aisle 34 to place the goods on the forklift 103 correspondingly on the storage positions 3 on both sides of the aisle 34.

[0100] Among them, in the first embodiment of the present application, it can be combined with Figure 5 、 Figure 6 and Figure 7 shown that there are multiple aisles 34 in the three-dimensional storage rack 2, and they are arranged side by side, so that the storage positions 3 with at least two levels of loading platforms symmetrically arranged with the aisle 34 as the center form multiple groups of storage positions 31 arranged side by side. Combining Figure 5 shown, in the first embodiment of the present application, on both sides of the three-dimensional storage rack 2 far from the aisle 34, support arms 35 are respectively arranged, and storage positions 3 facing the aisle 34 of the three-dimensional storage rack 2 are arranged on the support arms 35. And in the extending direction of the aisle 34 of the three-dimensional storage rack 2, and at the same height position, multiple storage positions 3 can be arranged, and the intervals between each storage position 3 can be equally spaced or unequally spaced, so as to meet the storage of goods of different lengths. It can be understood that based on the three-dimensional structure of the three-dimensional storage rack 2, multiple storage positions 3 can also be arranged in the vertical direction, and the intervals between each storage position 3 can be equally spaced or unequally spaced.

[0101] Among them, as Figure 6 and Figure 7As shown, the storage location 3 with at least two levels of loading platforms includes: a first-level loading platform 32 and a second-level loading platform 33 in a stepped structure, and the first-level loading platform 32 is arranged higher than the second-level loading platform 33. Goods of the same specification are symmetrically placed on the loading platforms of the same level that are symmetric about the lane 34. Specifically, if a first good is placed on the first-level loading platform 32 of the storage location 3 on the left, then another first good is placed on the first-level loading platform 32 of the storage location 3 on the right.

[0102] It should be noted that in the first embodiment of the present application, if the first good is the main beam of the vehicle frame, then one main beam is placed on the first-level loading platform 32 of the storage location 3 on the left, and another main beam is placed on the first-level loading platform 32 of the storage location 3 on the right. If the first good is an auxiliary beam paired with the main beam, then one auxiliary beam is placed on the second-level loading platform 33 of the storage location 3 on the left, and another auxiliary beam is placed on the second-level loading platform 33 of the storage location 3 on the right. That is, the storage locations 3 on the left and right are used to place paired main beams and auxiliary beams, and the loading platforms of the same level in the storage locations 3 on the left and right are used to place goods of the same specification. Of course, the first-level loading platform 32 can also place auxiliary beams, and the second-level loading platform 33 can also place auxiliary beams.

[0103] It should also be noted that considering the actual process of the forklift 103 of the stacker crane 1 placing goods, in the first embodiment of the present application, goods should be preferentially placed on the first-level loading platform 32. After the first-level loading platform 32 is full of goods, the goods are then placed on the second-level loading platform 33. Conversely, when the forklift 103 of the stacker crane 1 actually extracts goods, the goods placed on the second-level loading platform 33 should be preferentially extracted, and then the goods placed on the first-level loading platform 32 are extracted.

[0104] After the forklift 103 of the stacker crane 1 extracts goods from the storage location 3, the goods need to be transported to the next working station. Specifically, the outbound distribution end of the stereoscopic shelf 2 is connected to the next operation station through the outbound conveying device 30, so as to transport the goods at the outbound distribution end of the stereoscopic shelf 2 to the next operation station through the outbound conveying device 30. Among them, in the first embodiment of the present application, the next operation station can specifically be an assembly line 14 for assembling goods, that is, the goods are transported to the assembly line 14 through the outbound conveying device 30 for assembly.

[0105] Among them, in the first embodiment of the present application, the outbound conveying device 30 includes a high-level shuttling device and a low-level shuttling device. Specifically, in the vertical direction, the high-level shuttling device is arranged above the low-level shuttling device, and the connection between the outbound distribution end of the three-dimensional shelf 2 and the next operation station is established through the high-level shuttling device and the low-level shuttling device respectively. So as to realize that the high-level shuttling device transports the second goods received to the next operation station; and the low-level shuttling device transports the first goods received to the next operation station. Based on the fact that the specific structures of the high-level shuttling device and the low-level shuttling device are the same as those of the above-mentioned first shuttling device 20, no repetitive description will be made here.

[0106] The first embodiment of the present application provides an automated system 100 for storing and retrieving goods, including: an inbound conveying device 10, a stacker 1, a three-dimensional shelf 2 and an outbound conveying device 30; the inbound conveying device includes a first shuttling device 20, and the first shuttling device 20 is connected to the inbound distribution end of the three-dimensional shelf 2 to transport the goods to the inbound distribution end of the three-dimensional shelf 2 through the first shuttling device 20; the stacker 1 is movably arranged between the aisles 34 of the three-dimensional shelf 2, and is used to receive the goods distributed by the inbound distribution end and transport the goods to the storage locations 3 with at least two levels of bearing platforms symmetrically arranged with the aisle 34 as the center in the three-dimensional shelf 2, and to take out the goods from the storage location 3 to the outbound distribution end of the three-dimensional shelf 2; the outbound distribution end of the three-dimensional shelf 2 is connected to the next operation station through the outbound conveying device 30 to transport the goods at the outbound distribution end of the three-dimensional shelf 2 to the next operation station through the outbound conveying device 30. In the first embodiment of the present application, the goods produced on the production line can be directly transported to the inbound distribution end through the first shuttling device 20, and after the goods are reasonably distributed by the inbound distribution end, the goods are placed on the storage location 3 of the three-dimensional shelf 2 through the stacker 1, and when the goods need to be retrieved, the goods are directly transported to the next operation station through the stacker 1 and the outbound conveying device 30. In the process of storing and retrieving the goods, this system is completed by mechanization and intelligence, and the three-dimensional shelf 2 can store the goods without affecting the retrieval of the goods, realizing the improvement of the utilization rate of the warehouse space while reducing the time for storing and retrieving the goods, and thus reducing the cost of retrieving the goods.

[0107] The second embodiment of the present application provides a three-dimensional shelf 2 for storing and retrieving goods.

[0108] Specifically, as can be combined with Figure 5 、 Figure 6 and Figure 7 shown, there are multiple aisles 34 in the three-dimensional shelf 2, and they are arranged side by side, so that the storage locations 3 with at least two levels of bearing platforms symmetrically arranged with the aisle 34 as the center form multiple groups of storage locations 31 arranged side by side. Combined with Figure 5As shown in the figure, in the first embodiment of the present application, on both sides of the aisle 34 far from the stereoscopic shelf 2, support arms 35 are respectively provided, and on the support arms 35, storage locations 3 facing the aisle 34 of the stereoscopic shelf 2 are provided. And in the extending direction of the aisle 34 of the stereoscopic shelf 2 and at the same height position, a plurality of storage locations 3 can be provided, and the storage locations 3 can be arranged at equal intervals or unequal intervals, so as to meet the storage of goods with different lengths. It can be understood that based on the fact that the stereoscopic shelf 2 is a three-dimensional structure, in the vertical direction, a plurality of storage locations 3 can also be provided, and the storage locations 3 can be arranged at equal intervals or unequal intervals.

[0109] Among them, as Figure 6 and Figure 7 shown, the storage location 3 with at least two levels of load-bearing platforms includes: a first-level load-bearing platform 32 and a second-level load-bearing platform 33 in a stepped structure, and the first-level load-bearing platform 32 is arranged higher than the second-level load-bearing platform 33. Goods of the same specification are symmetrically placed on the load-bearing platforms of the same level that are symmetric about the aisle 34. Specifically, if a first piece of goods is placed on the first-level load-bearing platform 32 of the storage location 3 on the left side, then another first piece of goods is placed on the first-level load-bearing platform 32 of the storage location 3 on the right side.

[0110] It should be noted that in the first embodiment of the present application, if the first piece of goods is the main beam of the vehicle frame, then one main beam is placed on the first-level load-bearing platform 32 of the storage location 3 on the left side, and the other main beam is placed on the first-level load-bearing platform 32 of the storage location 3 on the right side. If the first piece of goods is an auxiliary beam paired with the main beam, then one auxiliary beam is placed on the second-level load-bearing platform 33 of the storage location 3 on the left side, and the other auxiliary beam is placed on the second-level load-bearing platform 33 of the storage location 3 on the right side. That is, the storage locations 3 on the left and right sides are used to place paired main beams and auxiliary beams, and the load-bearing platforms of the same level in the storage locations 3 on the left and right sides are used to place goods of the same specification. Of course, the first-level load-bearing platform 32 can also place auxiliary beams, and the second-level load-bearing platform 33 can also place auxiliary beams.

[0111] It should also be noted that considering the actual process of the forklift 103 of the stacker crane 1 placing goods, in the first embodiment of the present application, the goods should be preferentially placed on the first-level load-bearing platform 32. After the first-level load-bearing platform 32 is full of goods, the goods are then placed on the second-level load-bearing platform 33. On the contrary, when the forklift 103 of the stacker crane 1 actually extracts goods, the goods placed on the second-level load-bearing platform 33 should be preferentially extracted, and then the goods placed on the first-level load-bearing platform 32 are extracted.

[0112] The second embodiment of the present application provides a bulk shelf, including: a goods location 3 with at least two levels of loading platforms symmetrically arranged with the aisle 34 of the three-dimensional shelf 2 as the center; and the goods location 3 with at least two levels of loading platforms includes: a first-level loading platform 32 and a second-level loading platform 33 in a stepped structure, and the first-level loading platform 32 is arranged higher than the second-level loading platform 33, and goods of the same specification are symmetrically placed on the loading platforms of the same level symmetrically centered on the aisle 34. In the second embodiment of the present application, the goods location 3 of the three-dimensional shelf 2 is set to a structure with at least two levels of loading platforms, which not only simplifies the structure of the goods location 3, but also the loading platforms in a stepped structure can carry paired goods, realizing reasonable storage of goods.

[0113] The third embodiment of the present application provides a goods warehousing method, including: an in-warehouse conveying device 10, a stacker 1, a three-dimensional shelf 2, and a first shifting device 20 included in the in-warehouse conveying device 10. The first shifting device 20 is connected to the goods-in distribution end of the three-dimensional shelf 2, the stacker 1 is movably arranged between the aisles 34 of the three-dimensional shelf 2, and the three-dimensional shelf 2 includes a goods location 3 with at least two levels of loading platforms symmetrically arranged with the aisle 34 as the center.

[0114] In the third embodiment of the present application, corresponding to the goods in the first embodiment above, which can be the main beam or auxiliary beam of an automobile frame, in order to reasonably distribute and place the main beam and auxiliary beam on the goods location 3 of the three-dimensional shelf 2, it is necessary to combine the automated system 100 for accessing goods described in the first embodiment above to specifically explain the method described in the third embodiment of the present application. As Figure 8 shown, Figure 8 is a schematic flow chart of the goods warehousing method provided by the third embodiment of the present application. The method steps are as follows.

[0115] Step S801, the goods identification unit provided in the in-warehouse conveying device identifies the type of goods, and transports the identified and determined goods to the goods-in distribution end of the three-dimensional shelf through the first shifting device.

[0116] In this step, the goods-in distribution end includes a first goods-in distribution end 4 and a second goods-in distribution end 5, and in the vertical direction, the first goods-in distribution end 4 is arranged below the second goods-in distribution end 5. The first goods-in distribution end 4 is used to distribute and transport the first goods, and the second goods-in distribution end 5 is used to distribute and transport the second goods. It can be known from the automated system 100 for accessing goods described in the first embodiment above that corresponding to the goods to be transported, which can be the main beam or auxiliary beam of an automobile frame, the first goods is the bent beam among the main beam or auxiliary beam, simply referred to as the bent beam; the second goods is the straight beam among the main beam or auxiliary beam, simply referred to as the straight beam. In this embodiment, after the goods are identified and determined, the corresponding goods need to be diverted to the three-dimensional shelf 2 through the first goods-in distribution end 4 and the second goods-in distribution end 5.

[0117] Specifically, in order to identify whether the goods are the first type of goods or the second type of goods, a goods identification unit 13 is provided at the fourth conveyor line 11 or the second goods loading distribution end 5. The goods identification unit 13 is used to identify the identification code set on the goods and determine whether the goods are the first type of goods or the second type of goods. It should also be noted that in the first embodiment of the present application, when the goods pass through the second goods loading distribution end 5, the shapes of the goods can all be straight beams, that is, they are all the second type of goods. Then, through the bending beam processing equipment provided between the first goods loading distribution end 4 and the second goods loading distribution end 5, the straight beams are processed into bending beams, that is, the second type of goods are processed into the first type of goods, and then the first type of goods are transported to the first goods loading distribution end 4.

[0118] Further, the goods loading distribution end further includes: distribution lane positions that are misaligned with and docked one by one with the lanes 34 of the three-dimensional shelf 2, and a second transfer device 6; the second transfer device 6 includes a high-position second transfer device 61 and a low-position second transfer device 62, and the distribution lane positions 7 include a high-position distribution lane position and a low-position distribution lane position. Among them, the low-position second transfer device 62 is arranged between the first goods loading distribution end 4 and the low-position distribution lane position, and the high-position second transfer device 61 is arranged between the second goods loading distribution end 5 and the high-position distribution lane position. Then, the identified and determined goods are transported to the goods loading distribution end of the three-dimensional shelf 2 through the first transfer device 20. Specifically: the goods identification unit 13 determines whether the goods are the first type of goods or the second type of goods by identifying the identification code on the goods, and sends the determined first goods information or second goods information to the high-position second transfer device 61. After the first transfer device 20 transports the (already identified and determined information) goods to the second goods loading distribution end 5, the high-position second transfer device 61 transports the goods corresponding to the second goods information to the high-position distribution lane position according to the second goods information. After the first transfer device 20 transports the goods to the second goods loading distribution end 5, the high-position second transfer device 61 transports the goods corresponding to the first goods information to the first goods loading distribution end 4 according to the first goods information, and transports the goods corresponding to the first goods information to the low-position distribution lane position through the low-position second transfer device 62.

[0119] Step S802: Allocate the goods to the stacker located in the lane according to the number of lanes.

[0120] In the third embodiment of the present application, in order to make full and reasonable use of the storage space of the three-dimensional shelf 2, before the first type of goods reach the low-position distribution lane position and before the second type of goods reach the high-position distribution lane position, it is necessary to re-allocate the first type of goods or the second type of goods.

[0121] Specifically, corresponding to the foregoing, the aisles 34 of the three-dimensional storage rack 2 correspond one-to-one with the distribution lane positions 7, and there is a stacker 1 corresponding to each aisle 34. Therefore, as long as the number of aisles 34 and the number of the first goods or the second goods are known, the reasonable distribution of the goods can be achieved. Further, the number of aisles 34 and the number of goods are obtained respectively through the high-position second transfer device 61 and the low-position second transfer device 62. Among them, in the third embodiment of the application, the number information of the aisles 34 of the three-dimensional storage rack 2 can be obtained in advance through the total control unit of the system, and then the number information of the aisles 34 is respectively sent to the sub-control units correspondingly arranged in the high-position second transfer device 61 and the low-position second transfer device 62. And when the above-mentioned goods identification unit 13 identifies the goods, the corresponding goods quantity information is obtained, and the goods quantity information is respectively sent to the sub-control units in the corresponding high-position second transfer device 61 and low-position second transfer device 62, and the goods are allocated into the initial N groups.

[0122] Then, based on the fact that the stacker 1 can transport 2 goods each time, the first goods corresponding to the first goods distribution end 4 can be distributed according to the calculation rule of N / 2, and the second goods located at the second goods distribution end 5 can be distributed, and the distribution method is N / 2 groups, and the N / 2 groups of goods (the first goods or the second goods) are sequentially and circularly distributed to the stackers 1 corresponding to the aisles 34 according to the sorting of the aisles 34.

[0123] In an embodiment, taking the first goods as an example, the number of the first goods is 6 pieces, that is, 6 main beams of the same specification (model). The number of aisles 34 is 2, and the distribution aisles 71 between the corresponding low-position distribution lane positions are also 2. Among them, 2 aisles 34 can be defined as the first aisle 34 and the second aisle 34, and the distribution aisle 71 is defined as the first distribution aisle 71 and the second distribution aisle 71. The above-mentioned goods are grouped into 3 groups, and there are 2 main beams in each group. The low-position second transfer device 62 obtains the distribution information, that is, when the low-position second transfer device 62 transports 6 main beams, when it reaches the first distribution aisle 71, it can first place 2 of the main beams, and then continue to move. When it reaches the second distribution aisle 71, it places 2 of the main beams. And based on the fact that the low-position second transfer device 62 is a chain transfer machine, it can continue to turn back to the first distribution aisle 71 and place the last 2 main beams.

[0124] It should be noted that the specific execution instructions of the above method can be implemented by the cooperation of the overall control unit of the system and the sub-control unit of the low-position second transfer device 62. Among them, the overall control unit and the sub-control unit can be specific products in the existing technologies such as WES (Warehouse Executing System), WMS (Warehouse Management System), and WCS (Warehouse Control System). Based on the fact that the above products are existing technologies, the specific transmission method of the control instructions can be carried out according to the existing solutions, and the third embodiment of the present application does not make specific limitations here.

[0125] It should also be noted that in actual applications, there are multiple aisles 34 in the stereoscopic shelf 2. For example, 4 aisles 34 are set, and at this time, there are 6 main beams. In one case, the number of aisles 34 can be set to 3 in the system, and then the main beams are grouped into 3 groups, with 2 main beams in each group. The 4 aisles 34 can be defined as the first aisle 34, the second aisle 34, the third aisle 34, and the fourth aisle 34, and the distribution aisles 71 are defined as the first distribution aisle 71, the second distribution aisle 71, the third distribution aisle 71, and the fourth distribution aisle 71. The low-position second transfer device 62 obtains the distribution information. When transporting 6 main beams, when it reaches the first distribution aisle 71, it can first place 2 of the main beams, and then continue to move. When it reaches the second distribution aisle 71, it places 2 of the main beams. When it reaches the third distribution aisle 71, it places the last 2 main beams. Then, when the next batch of 6 main beams arrives, the low-position second transfer device 62 places 2 of the main beams in the fourth distribution aisle 71, and then moves to the first distribution aisle 71 to place 2 of the main beams, and finally places the remaining 2 main beams in the second distribution aisle 71. From the above description, it can be seen that when the goods are distributed in the high-position distribution bays and the low-position distribution bays, they follow the method of equal distribution and cyclic distribution, that is, for 4 distribution bays 7, 2 main beams are distributed to each distribution bay 7, and they are distributed in a cycle according to the distribution bay numbers 1-2-3, 2-3-4, 3-4-1, 4-1-2.

[0126] Step S803, the goods identification unit determines whether the goods need to be paired. If so, it controls the stacker to transport the goods to the goods location that can be paired with the goods; if not, it transports the goods to the vacant goods location.

[0127] After the goods are distributed through the high-level distribution lane position and the low-level distribution lane position, they need to be further distributed on the storage location 3 of the stereoscopic shelf 2 by the stacker 1. Specifically, the storage location 3 of the stereoscopic shelf 2 with at least two levels of bearing platforms includes: a first-level bearing platform 32 and a second-level bearing platform 33 in a stepped structure, and the first-level bearing platform 32 is arranged higher than the second-level bearing platform 33. Goods of the same specification are symmetrically placed on the bearing platforms of the same level that are symmetric about the lane 34.

[0128] Specifically, obtain the first type of goods placed on the first-level bearing platform 32 in a storage location 3, and obtain the second type of goods transported by the current stacker 1; determine whether the first type and the second type are paired types. If so, control the stacker 1 to transport the goods corresponding to the second type to the second-level bearing platform 33 in the same storage location 3. For example, it can be combined with Figure 5 , if the goods of the first type are the main beams of the vehicle frame, then one main beam is placed on the first-level bearing platform 32 of the storage location 3 on the left, and the other main beam is placed on the first-level bearing platform 32 of the storage location 3 on the right. If the goods of the second type are the auxiliary beams paired with the main beams, then one auxiliary beam is placed on the second-level bearing platform 33 of the storage location 3 on the left, and the other auxiliary beam is placed on the second-level bearing platform 33 of the storage location 3 on the right. That is, the storage locations 3 on the left and right are used to place paired main beams and auxiliary beams, and the bearing platforms of the same level in the storage locations 3 on the left and right are used to place goods of the same specification. Of course, auxiliary beams can also be placed on the first-level bearing platform 32, and auxiliary beams can also be placed on the second-level bearing platform 33. Of course, if there is no paired type, transport the goods to the vacant storage location 3.

[0129] It can be combined with Figure 9 For example, to place main beams of the same specification, Figure 9 in (a) of, there are 2 main beams carried on the forklift fork 103, and the forklift fork 103 moves to the storage location 3 on the left. Figure 9 in (b) of, the forklift fork 103 extends, and places the main beam outside the forklift fork 103 on the first-level bearing platform 32, and the main beam inside the forklift fork 103 does not fall. In Figure 9 in (c) of, the forklift fork 103 contracts and moves to the storage location 3 on the right. Figure 9 in (d) of, the forklift fork 103 extends to the storage location 3 on the right and places the main beam on it on the first-level bearing platform 32. That is, it realizes that goods of the same specification are symmetrically placed on the bearing platforms of the same level that are symmetric about the lane 34.

[0130] The third embodiment of this application provides a method for goods warehousing. By identifying the types of goods, the goods are accurately transported to the corresponding incoming goods distribution terminals, and the goods are evenly distributed according to the number of aisles 34. Moreover, the evenly distributed goods can be paired when placed in the storage locations 3 of the stereoscopic shelf 2. This not only improves the utilization rate of the storage space of the stereoscopic shelf 2 but also realizes reasonable and accurate storage of the goods, thereby improving the storage efficiency of the goods.

[0131] It should also be noted that when it is necessary to extract the goods in the stereoscopic shelf 2, it can be controlled and completed through the above-mentioned WES, WMS, and WCS systems. Briefly speaking, WES issues a production instruction. After WMS receives this production instruction, it issues an outbound instruction. WCS obtains the outbound instruction and controls the stacker 1 to carry out goods outbound. Among them, when the goods are outbound, they are outbound in the way that the left and right main and auxiliary beams go out at the same time, which is convenient for the subsequent assembly of the assembly line 14.
