Fig. 7 is a flowchart of a cargo transportation method according to a fourth embodiment of the present disclosure, where in the present embodiment, for a case where a conveying mechanism of a temporary storage rack is multi-tiered, the cargo transportation method according to the present embodiment is that, on the basis of the embodiment shown in fig. 6, steps of determining a conveying direction, determining a preset tier, and determining a conveying speed of the conveying mechanism are added after step S601, as shown in fig. 7, the cargo transportation method according to the present embodiment may include the following steps:

step S701, determining goods to be transported.

Step S702, determining a preset layer of the conveying mechanism corresponding to the goods to be transported.

The preset layer is a layer of a conveying mechanism used for conveying, temporarily storing or placing goods to be conveyed.

In some embodiments, each layer of the elevator corresponds to one layer of the temporary storage rack, and each layer of the temporary storage rack corresponds to one layer of the conveyor line assembly, so step S702 may be omitted.

Specifically, the preset layer of the transport mechanism corresponding to the goods to be transported can be determined according to the task order corresponding to the goods to be transported. That is, when initiating a task order, a preset layer of the transport mechanism corresponding to each to-be-transported cargo may be configured in the task order.

Specifically, the preset layer of the conveying mechanism corresponding to the goods to be transported can be determined according to the size information of the goods to be transported.

The size information of the goods to be transported may include the width of the goods to be transported, and may also include the height of the goods to be transported.

In some embodiments, the size information of each layer of the conveying structure of the buffer storage rack may be different, such as different heights or different widths, and therefore, different preset layers need to be determined for the goods with different size information, so as to facilitate the transportation of the goods with various sizes.

Specifically, each layer of the conveying mechanism of the temporary storage rack can correspond to each layer of the conveying line assembly one to one. When the direction of transfer of goods that await transportation is first direction, the goods that await transportation promptly need loop through lifting machine 10, the goods shelves and the transfer line subassembly of keeping in transit and transport to the operation panel, accomplish the warehouse-out of the goods that await transportation through processing such as the letter sorting of operation panel, packing. After determining the goods to be transported, such as after determining the goods identifier of the goods to be transported, the preset layer of the transport mechanism corresponding to the goods to be transported may be determined based on the number and/or location of the goods being transported on each layer of the transport line assembly before the goods to be transported are transported to the temporary storage shelf.

Further, the layer with the least quantity of the goods being transported by the conveyor line assembly can be determined as the preset layer of the conveying mechanism corresponding to the goods to be transported; or, the layer of the goods transported by the transporting line assembly, which is farthest from the transporting mechanism or the temporary storage rack, may be determined as the preset layer of the transporting mechanism corresponding to the goods to be transported; or for each layer of the conveying line assembly, the first number of the goods being transported on the layer at the current moment and the first distance between the goods closest to the conveying mechanism or the temporary storage rack and the conveying mechanism or the temporary storage rack in the layer of the goods being transported can be determined, and the layer with the smallest first number of the goods being transported in each layer with the first distance larger than the preset distance is determined to be the preset layer of the conveying mechanism corresponding to the goods to be transported.

Specifically, when the transfer direction of the goods to be transported is the second direction, the goods to be transported need to pass through the transfer line assembly, the temporary storage shelf and the elevator in sequence to be transported to the fluent shelf, and then the goods to be transported are carried to the warehouse position corresponding to the warehouse by the robot, and the warehouse entry of the goods to be transported is completed. After determining the goods to be transported, before the goods to be transported is transported to the temporary storage rack, the preset layer of the transport mechanism corresponding to the goods to be transported may be determined based on the second preset layer of the transport mechanism corresponding to each goods before the goods to be transported that is being transported on the transport line assembly.

Further, for each layer of the conveying mechanism, the second quantity of each cargo before the cargo to be transported, which is being transported on the conveying line assembly corresponding to the layer, may be counted, and it is determined that one layer of the corresponding conveying mechanism with the smallest second quantity is the preset layer of the conveying mechanism corresponding to the cargo to be transported.

In some embodiments, the transfer speeds of different levels of the transfer mechanism may be different, and the maximum number of items that may be transported on different levels may also be different. The difference between the maximum number and the second number corresponding to each layer of the conveyor line mechanism may be calculated, and the layer of the conveyor line mechanism having the maximum difference between the maximum number and the second number is determined as the preset layer of the conveyor line mechanism corresponding to the cargo to be transported.

Step S703, determining a conveying direction of the goods to be transported according to the transportation task of the goods to be transported and/or the position of the goods to be transported.

Wherein the transportation task may be part of an order task of the warehousing system.

Specifically, if the transportation task is an ex-warehouse task, determining that the conveying direction of the goods to be transported is a first direction; and if the transportation task is a warehousing task, determining that the conveying direction of the goods to be transported is a second direction. The type of the transportation task can be determined according to the type of the order task, when the type of the order task is an ex-warehouse type, each transportation task divided by the order task is an ex-warehouse task, and when the type of the order task is an in-warehouse type, each transportation task divided by the order task is an in-warehouse task.

Specifically, the conveying direction of the goods to be transported can be determined according to the current position of the goods to be transported.

Further, if the goods to be transported are determined to be positioned on a lifting machine, a fluent goods shelf, a robot or a goods shelf and the like according to the current position of the goods to be transported, determining that the conveying direction of the goods to be transported is a first direction; and if the goods to be transported are determined to be positioned on the conveying line assembly or the operation table and the like according to the current position of the goods to be transported, determining that the conveying direction of the goods to be transported is the second direction.

Further, if the transportation task corresponding to the goods to be transported is an ex-warehouse task and the goods to be transported is located on a lifting machine, a fluent goods shelf, a robot or a goods shelf and the like according to the position of the goods to be transported, determining that the conveying direction of the goods to be transported is a first direction; and if the transportation task corresponding to the goods to be transported is a warehousing task and the goods to be transported is positioned on the conveying line assembly or the operation platform according to the position of the goods to be transported, determining that the conveying direction of the goods to be transported is the second direction.

Step S704, determining a conveying direction of a preset layer of the conveying mechanism based on the conveying direction of the cargo to be transported.

Specifically, when the conveying direction of the goods to be transported is a first direction, the conveying direction of a preset layer of the conveying mechanism is determined to be a third direction; and when the conveying direction of the goods to be conveyed is the first direction, determining that the conveying direction of the preset layer of the conveying mechanism is the fourth direction. The goods to be transported are transported to the transporting line assembly from the elevator by the preset layer of the transporting mechanism in the third direction; and in the fourth downward direction, the goods to be transported are transported to the elevator by the preset layer of the transport mechanism from the transport line assembly.

Illustratively, the third direction is a direction corresponding to point B pointed by point a of the preset layer of the transport mechanism, and the fourth direction is a direction corresponding to point a pointed by point B of the preset layer of the transport mechanism, where point a and point B are points on two opposite edges of the transport mechanism.

Step S705, determining a transfer speed of the transfer mechanism according to the goods corresponding to the hoist or the goods transported by the transfer line assembly.

The goods corresponding to the hoister can be the goods which need to be hoisted to operate, can comprise the goods which need to be delivered from the warehouse on the fluent goods shelf, and can also comprise the goods which need to be delivered into the warehouse and are temporarily stored on the goods shelf and positioned in front of the goods to be transported.

In some embodiments, the number of tiers of the transport mechanism and elevator may not match.

Specifically, when the conveying direction of the goods to be conveyed is the first direction, before the goods to be conveyed are conveyed to the conveying mechanism, the conveying speed of the conveying mechanism is determined according to each goods being conveyed on the conveying line assembly.

Further, the conveying speed of the conveying mechanism can be determined according to the position of each cargo being conveyed on the preset layer of the conveying line assembly, so that when the cargo to be conveyed is conveyed onto the conveying line assembly, the safe distance is kept between the cargo to be conveyed and the cargo closest to the cargo to be conveyed on the conveying line assembly.

Specifically, when the conveying direction of the goods to be conveyed is the second direction, before the goods to be conveyed are conveyed to the conveying mechanism, the conveying speed of the conveying mechanism is determined according to the goods which need to be operated by the elevator at present.

Furthermore, the operation time of the hoister can be determined according to the target layer of the fluent goods shelf corresponding to each goods corresponding to the hoister and the preset layer of the temporary storage goods shelf, and the transmission speed of the transmission mechanism is determined according to the operation time, so that after the hoister completes each operation before the goods to be transported, the transmission mechanism is controlled to transport the goods to be transported to one end, close to the hoister, of the transmission mechanism, and then the goods to be transported are transported to the target layer corresponding to the fluent goods shelf through the hoister.

Further, if the operation time is longer than the preset time, the preset layer of the conveying mechanism is controlled to stop running for a second time, and then the operation is carried out based on the minimum conveying speed. The second time is determined by the difference between the operation time and the preset time.

Specifically, when the conveying direction of the goods to be conveyed is the first direction, the target time required for conveying the last goods to the target position is determined according to the position of the last goods currently being conveyed on the preset layer of the conveying line assembly and the conveying speed of the conveying line assembly, and the conveying speed of the conveying mechanism is determined according to the target time, so that the goods to be conveyed are conveyed to the conveying line assembly after the target time. The target position is a position which is far away from the goods access opening of the temporary storage shelf close to the conveying line assembly and is larger than the safety distance.

Specifically, when the transportation direction of the goods to be transported is the second direction, the operation time required for the elevator to transport each corresponding goods to the corresponding target position can be determined according to the number of layers of the elevator and the position of each corresponding goods of the elevator, wherein the target position can be a target layer of the fluent goods shelf or a preset layer of the conveying mechanism of the temporary storage goods shelf, and then the conveying speed of the conveying mechanism is determined based on the operation time.

Further, if there are a plurality of goods to be transported and the preset layers corresponding to at least two goods to be transported are different, for example, the preset layers are the third preset layer and the fourth preset layer, the conveying directions and the conveying speeds of the third preset layer and the fourth preset layer may be determined by the above method, and the conveying directions and the conveying speeds of the third preset layer and the fourth preset layer may be different.

And step S706, controlling the preset layer of the conveying mechanism to run along the conveying direction and at the conveying speed.

Step S707, based on the preset layer of the conveying mechanism, the goods to be conveyed are conveyed to the conveying line assembly or the elevator.

Specifically, when the direction of transfer of the goods to be transported is the first direction, the goods to be transported is transported to the conveyor line assembly based on the preset layer of the transport mechanism, so that the goods to be transported is transported to the operation table through the conveyor line assembly. And when the conveying direction of the goods to be conveyed is the second direction, the goods to be conveyed are conveyed to the elevator based on the preset layer of the conveying mechanism, so that the goods to be conveyed are conveyed to the target layer of the fluent goods shelf through the elevator.

In this embodiment, after determining the goods to be transported, a preset layer of a suitable conveying mechanism of the temporary storage rack is allocated to the goods to be transported, so that the goods to be transported are transported through the preset layer, and the efficiency of goods transportation is improved; meanwhile, the conveying direction of the preset layer of the conveying mechanism is determined based on the conveying direction of the goods to be conveyed, and the conveying speed of the preset layer of the conveying mechanism is determined based on the conveying condition of the upstream or downstream equipment of the temporary storage rack, so that the goods to be conveyed are conveyed to the upstream or downstream equipment of the conveying mechanism as fast as possible on the premise of ensuring the safety of the transportation, the time for conveying the goods is shortened, and the efficiency of the goods transportation is further improved; the transportation of goods to be transported is carried out based on the determined direction of conveyance and the determined speed of conveyance on the preset layer, so that the upstream equipment and the downstream equipment of the temporary storage shelf, namely the elevator and the conveying line assembly, can carry out the operation of subsequent tasks more quickly, the operating efficiency of the elevator and the conveying line assembly is improved, and the goods transportation efficiency of the warehousing system is improved.

For example, the detection information may be a detection image of the goods to be transported, such as a detection image of a preset area including a goods identification code attached thereto, where the goods identification code may be in the form of a two-dimensional code, a barcode, a code, or the like, and the detection image may also be an image including the whole goods to be transported excluding the bottom surface, so as to determine whether the surface of the goods to be transported is damaged.

Specifically, the detection information of the goods to be transported can be acquired based on the goods detection device arranged on the conveying mechanism. The cargo detection device may include one or more of a vision sensor, a weight sensor, a pressure sensor, an infrared sensor, and the like.

Step S804, based on the detection information, judging whether the goods to be transported meet the transportation condition.

Specifically, whether the cargo identification in the detection information is consistent with the preset identification or not can be judged, and if not, it is determined that the cargo to be transported does not meet the transportation condition.

Specifically, when the goods identification in the detection information is consistent with the preset identification, whether the goods to be transported are damaged or not can be judged based on the detection information, and if yes, the goods to be transported do not meet the transportation condition.

Specifically, whether the weight of the goods in the detection information is within a preset weight range or whether the weight of the goods is consistent with the preset weight or not can be judged, and if not, it is determined that the goods to be transported do not meet the transportation condition.

Wherein, predetermine the weight scope and can be the transport mechanism of the goods shelves of keeping in or the safe weight scope that the layer can be transported in predetermineeing of transport mechanism.

In some embodiments, the preset weight ranges for different layers of the transport mechanism may be different. For example, the first layer corresponds to the largest preset weight range, and the highest layer corresponds to the smallest preset weight range.

Specifically, whether the size of the goods in the detection information is within a preset size range or whether the size of the goods is consistent with a preset size or not can be judged, and if not, the goods to be transported are determined not to meet the transportation condition.

The preset size range can be a safe size range which can be transported by a conveying mechanism of the temporary storage shelf or a preset layer of the conveying mechanism.

In some embodiments, the predetermined size ranges for different layers of the transport mechanism may be different.

judging whether the goods identification of the goods to be transported is a preset identification; judging whether the size of the goods is within a preset size range or not; and judging whether the weight of the goods is within a preset weight range.

And if at least one item is not, determining that the goods to be transported do not meet the transportation condition.

Specifically, it may be determined whether the weight of the cargo is within a preset weight range; if so, judging whether the goods identifier is a preset identifier or not; if so, judging whether the size of the goods is in a preset size range, and if so, determining that the goods to be transported meet the transportation condition.

And step S805, if yes, the goods to be transported are transported to the transport line assembly or the elevator based on the preset layer of the transport mechanism.

Specifically, when the goods to be transported satisfy the transportation condition, the transportation of the goods to be transported is carried out on the basis of the preset layer of the transport mechanism so as to transport the goods to be transported to the transport line assembly or the elevator.

and determining the direction of a preset layer of the conveying mechanism to be the opposite direction of the conveying direction of the goods to be conveyed so as to convey the goods to be conveyed back along the original path.

Specifically, when the goods to be transported do not satisfy the transportation condition, the goods to be transported need to be transported back along the transportation route thereof, that is, the transportation direction of the preset layer of the transportation mechanism is reversed, so that the goods to be transported is transported back along the original route.

Step S806, when the conveying direction of the goods to be transported is the first direction and the goods to be transported does not meet the transportation condition, controlling the robot to convey the goods to be transported to an operation table or a storage position corresponding to the goods to be transported.

Specifically, when the conveying direction of the goods to be transported is the first direction, and the goods to be transported does not meet the transportation condition, in order to transport the goods to be transported back to the original storage position, that is, the storage position corresponding to the goods to be transported, a control instruction of the robot can be generated, so that the robot is controlled to transport the goods to be transported from the preset layer of the conveying mechanism to the original storage position of the goods to be transported.
