It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
For the unmanned warehouse, unmanned goods loading and unmanned goods picking are the core of the unmanned warehouse, and therefore whether the unmanned goods loading and the unmanned goods picking are efficient and accurate is a key index for normal operation of the unmanned warehouse.
However, the prior art process of unmanned shipment is: as shown in fig. 2, the existing task allocation software generates a plurality of loading tasks according to the information of goods to be loaded and the storage condition information of the warehouse, each loading task includes the information of goods and the storage position of the goods, and the storage position of the goods is determined according to the recommended storage position policy of the task allocation software and the storage condition information of the warehouse. The task allocation software issues a plurality of loading tasks to a terminal used by a worker, and the worker loads corresponding goods to corresponding goods shelves according to each loading task, specifically comprising: the method comprises the steps that a worker selects a loading task through a terminal, the identifier of the selected loading task is sent to task distribution software through the terminal, the task distribution software controls an unmanned vehicle to go to the original position of a goods shelf corresponding to the loading task according to the identifier of the loading task and controls the unmanned vehicle to drag the goods shelf to an upper stand, the worker scans a bar code of goods to be loaded and a bar code of a storage position of the goods shelf at the upper stand, when the worker confirms that the goods belong to the loading task, the goods are manually placed at the storage position of the goods shelf, the goods loaded on the goods shelf and the quantity of the goods are manually confirmed, the quantity of the loaded goods input by the worker is uploaded to the task distribution software through the terminal, and the task distribution software controls the unmanned vehicle to drag the goods shelf to the original position of the goods shelf after receiving.
From the above, it can be seen that: first, the loading requires human intervention and the staff plays an important role, and thus the automation of the existing loading is not high. Secondly, when the same kind of goods is loaded, the quantity of the goods loaded on different goods shelves is different, the problem is easy to occur when the quantity of the loaded goods is manually confirmed, and the risk of making mistakes is higher during the peak period, so that the accuracy of the loaded goods is not high finally. Thirdly, because a goods often stores in a plurality of goods shelves, multiple goods probably store in a goods shelf, so the number of times that unmanned aerial vehicle dragged goods shelves and the goods shelves number of dragging is more, and is greatly promoted in the market, great holiday activity, under the huge condition of the volume of flow of getting in stocks, drag number of times and goods shelves number and can sharply increase, and frequently drag the efficiency that goods shelves can lead to getting in stocks not high, and the goods easy damaged problem of getting in stocks. Moreover, one worker occupies one workbench, at the same time, the worker can only process one loading task, and a plurality of shelves corresponding to the loading task are processed in sequence, so that the loading efficiency is poorer.

In addition, after the shunting instruction and the placing instruction are generated, the server issues the shunting instruction to the shunting device, and the issuing method can be that the shunting device issues the shunting device by using an IP address of the shunting device, and the shunting device shunts the goods on the main goods loading channel to the target goods loading channel according to the shunting instruction. It should be noted that, when the goods on the main loading channel are multiple, the shunting device needs to shunt the multiple goods to the multiple target supporting loading channels according to the shunting instruction, so that the multiple target supporting loading channels are used for loading the goods to the corresponding storage positions, and the loading efficiency is further improved.
And step S104, if a second goods loading instruction sent by the target branch goods loading channel is received, wherein the second goods loading instruction carries the goods information, controlling a target placing device to place the goods from the target branch goods loading channel to a target storage position according to the placing instruction.
In this step, it should be noted that, a detection device is disposed on the target branch loading channel, and when the detection device detects the goods, a second loading instruction is generated and issued. In specific implementation, when receiving the goods information, the server immediately issues the placement instruction to the target placement device, and the issuing method may be that the IP address of the target placement device is used to issue the placement instruction to the target placement device, and the target placement device places the goods on the target goods loading channel to the target storage position according to the placement instruction. When receiving the information of a plurality of goods, the respective target placement devices place the goods on the respective target loading channels to the respective target storage positions according to the respective placement instructions, and in the process, all the target placement devices can load the goods simultaneously, so that the goods loading efficiency is further improved. In addition, the specific manner of carrying out this step can be referred to the second embodiment.
In order to solve the problems in the prior art, a second embodiment of the present invention provides a method for loading goods, which can be applied to a server, and the method includes:
the method comprises the steps of firstly, receiving a first goods loading instruction sent by a main goods loading channel, wherein the first goods loading instruction carries goods information, and matching a corresponding goods loading task according to the goods information.
In the step, after the corresponding goods loading tasks are matched, the goods loading tasks are sent to the terminal used by the staff, and goods information and storage positions are displayed on the terminal, so that the staff can conveniently check the goods. Wherein, the goods information may include: the name of the goods, the manufacturer, the production batch, the goods identification code, the number of the goods and the like. Since the goods are storage locations stored on shelves of the warehouse, the storage locations may include: the position of the warehouse where the goods should be stored, the name of the shelf where the goods should be stored, and the positional relationship of the actual position where the goods should be stored with respect to the shelf (i.e., the storage position of the shelf). Illustratively, the storage location may be the nth bin of the 2 nd shelf of the S-th warehouse.
It should be noted that one end of the main loading channel is located at the temporary storage position of the goods, one end of the main loading channel is located at the shunting device, and the main loading channel can be a conveyor belt used for conveying the goods from the temporary storage position of the goods to the shunting device. In addition, the detection device of the main goods loading passage can adopt a commodity photoelectric scanner when being implemented, and of course, other detection devices can be adopted as long as the information of the goods can be identified, so that the distribution is carried out.
And secondly, establishing a corresponding relation among the goods loading channel, the placing device and the storage position in the goods loading task in advance.
In this step, a placement device may be provided on each shelf. One end of each goods feeding channel is positioned in front of one goods shelf, and the other end of each goods feeding channel is positioned in the shunting device. Each of the branch loading passages may be a conveyor belt for transporting goods from the diversion device to a shelf. Meanwhile, detection devices are arranged on two sides of one end of each goods supporting channel, and the detection devices of the goods supporting channels can adopt commodity photoelectric scanners when being specifically implemented, and can be other detection devices as long as goods information can be identified, so that goods can be loaded. Therefore, the branch loading channel, the placing device and the goods shelf are in one-to-one correspondence, so that the corresponding relations among the branch loading channel, the placing device and all the storage positions can be established in advance, and the corresponding relations among the storage positions in the branch loading channel, the placing device and the loading task can be inquired from the corresponding relations according to the storage positions in the loading task.
And thirdly, selecting a target storage position from the storage positions to be loaded in the loading task.
At this step, the method of selecting the target storage location may be arbitrarily drawing from the storage locations to be shipped. It should be understood that a person skilled in the art may flexibly set the selection method without affecting the embodiments of the present invention, for example, sequentially selecting from storage locations to be stocked in the order of storage locations set in advance.
And fourthly, generating a shunting instruction and a placing instruction according to the goods information in the loading task, the target storage position and the corresponding relation among the loading channel, the placing device and the storage position in the loading task.

In specific implementation, when receiving the goods information, the server immediately issues the confluence instruction to the confluence device, the issuance method may be that the confluence device is issued by using the IP address of the confluence device, the confluence device places the goods from the target goods-sorting channel to the main goods-sorting channel connected with the workbench according to the confluence instruction, and the confluence device may employ a mechanical arm. When receiving a plurality of goods information, the confluence device places respective goods from respective target branch goods channels to a main goods-picking channel connected with the workbench together according to the confluence instruction, and the goods flow to the workbench simultaneously, so that the goods-picking efficiency is further improved. In addition, the specific manner of carrying out this step can be referred to the second embodiment.
In order to solve the problems of the prior art, a second embodiment of the present invention provides a method for picking up goods, which can be applied to a server, the method comprising:
the method comprises the steps of firstly, acquiring a goods picking task, wherein the goods picking task carries goods information, taking out position information and workbench information.
In the step, after the picking task is obtained, the picking task is sent to a terminal used by a worker, and the information of the goods, the taking-out position and the information of a workbench are displayed on the terminal, so that the worker can conveniently check the information. Wherein, the goods information may include: the name of the goods, the manufacturer, the production batch, the goods identification code, the number of the goods and the like; since the goods are stored in the storage locations of the shelves of the warehouse, the retrieval position may include: the position relation of the warehouse position where the goods should be taken out, the shelf name where the goods should be taken out and the actual position where the goods should be taken out relative to the shelf. Illustratively, the retrieval location may be the nth bin of the 2 nd rack of the S warehouse.
And secondly, establishing a corresponding relation among a goods sorting channel, a taking-out device and a taking-out position in the goods sorting task in advance.
In this step, a take-out device may be provided for each shelf. One end of each goods sorting channel is positioned in front of one goods shelf, and the other end of each goods sorting channel is positioned in the confluence device. Each branch goods passage may be a conveyor belt for transporting goods from a shelf to the merge device. Meanwhile, detection devices are arranged on two sides of the other end of each branch goods channel. Therefore, the order channel, the taking-out device and the goods shelf are in one-to-one correspondence, so that the corresponding relations among the order channel, the taking-out device and all the taking-out positions can be established in advance, and the corresponding relations among the order channel, the taking-out device and the taking-out positions in the order task can be inquired from the corresponding relations according to the taking-out positions in the order task.
And thirdly, selecting a target taking-out position from the taking-out positions of the goods to be picked in the picking task.
At this step, the method of selecting the target picking position may be arbitrarily drawing from the picking positions to be picked. It should be understood that a person skilled in the art may flexibly set the selection method without affecting the embodiments of the present invention, for example, sequentially selecting from the picking positions to be picked in the order of the preset picking positions.
And fourthly, generating a taking-out instruction and a converging instruction according to the corresponding relation among the goods information, the target taking-out position, the workbench information, the goods sorting channel, the taking-out device and the taking-out position in the goods sorting task.
In the step, in concrete implementation, a branch picking channel corresponding to the target picking position is inquired from the corresponding relation among the branch picking channel, the picking device and the picking position in the picking task and is used as the target branch picking channel; inquiring a taking-out device corresponding to the target taking-out position from the corresponding relation among the order-picking channel, the taking-out device and the taking-out position in the order-picking task to be used as a target taking-out device; generating a take-out instruction according to the goods information, the target order channel, the target take-out position and the target take-out device; and generating a confluence instruction according to the goods information, the target order-sorting channel and the workbench information. It should be understood that if a pickup device is elected as a target pickup device a plurality of times, the number of elected times of the target pickup device is the number of goods picked by the pickup device.
And fifthly, controlling the target taking device to pick the goods from the target taking position according to the taking instruction and placing the goods on the target goods sorting channel.
In this step, the goods are picked out from the target picking position and placed on the target branch picking passage by the mechanical arm, for example, the specific process may be: the mechanical arm is lifted or lowered to the layer surface of the target taking-out position, picks the goods from the corresponding storage position of the layer surface and places the goods on the target goods sorting channel.
And sixthly, if a goods picking instruction sent by the target goods sorting channel is received, wherein the goods picking instruction carries the goods information, the confluence device is controlled to place the goods from the target goods sorting channel to a main goods picking channel connected with a workbench according to the confluence instruction.
In this step, it should be noted that one end of the main picking channel is located at the work table, and the other end is located at the confluence device, and the main picking channel may be a conveyor belt for conveying goods from the confluence device to the work table. In addition, the detection device of the goods sorting passage may be a commodity photoelectric scanner in specific implementation, and of course, other detection devices may be used as long as the goods information can be recognized, so that the goods information is merged. Furthermore, the confluence device is disposed between the main picking passage and the branch picking passage, thereby facilitating the confluence of the goods to the main picking passage. Also, the detailed implementation of this step can refer to the first embodiment.
Seventhly, receiving feedback information returned by the target taking device, wherein the feedback information comprises the number of the goods currently picked out from the target taking position by the target taking device; calculating an actual pick number of the target picking position according to the number of the goods currently picked from the target picking position by the target picking device and the number of the goods already picked from the target picking position; and if the actual picking number is equal to the picking number upper limit of the target picking position in the picking task, taking the picking positions except the target picking position in the picking task as the picking positions to be picked.
In this step, when the actual picking number is equal to the upper limit of the picking number of the target picking position in the picking task, it is confirmed that the goods can not be picked from the target picking position in the picking task, and thus the picking positions other than the target picking position are taken as the picking positions to be picked. And when the actual picking number is smaller than the picking number upper limit of the target picking position in the picking task, confirming that the goods can be continuously picked from the target picking position, so that the target picking position is still used as the picking position of the goods to be picked. In addition, the actual picking number of the target picking position is calculated in a server mode, so that the actual picking number of each picking position can be determined, errors caused by manual confirmation of the actual picking number are avoided, and the picking accuracy is improved. It should be understood that, in this step, the number of the goods that have been picked from the target take-out position refers to the number of the goods that have been picked from the target take-out position in the present picking task.
The following describes the picking process with a specific example, with reference to fig. 8 and 9, as follows:
