The packing area is divided into several packing partitions according to the distribution areas. A number of sequentially arranged packing ports and buffer walkways connecting the packing ports to the main hanging chain loop are provided in each packing partition. By ensuring that the distribution areas of each packing partition are the same, there is no need for manual classification according to the distribution areas, nor is it necessary to set up an area waiting for transportation. The packing partition is equivalent to the area waiting for transportation, solving the "last mile" problem of the hanging chain system, greatly reducing the cost of conveying and sorting, and improving the efficiency of conveying and sorting.

Description

Technical Field

[0001] The invention relates to the field of suspension chain systems, in particular to a suspension chain system and a dispatching method thereof. Background Art

[0002] In recent years, with the rapid development of technologies such as computers and sensors, the application of automated warehousing and logistics technology has also advanced rapidly with the pace of development. It is currently widely used in the fields of medicine, books, e-commerce, etc. In the process of human transformation from manual warehousing to fully automated warehousing, the product technology has been updated and iterated from generation to generation, and the suspension chain system has also come into being. The suspension conveyor chain (referred to as the suspension chain) uses ball bearings as chain wheels. It can turn and climb at will and can adapt to various geographical conditions. It is mainly used in aerial distribution of materials. It has many advantages such as small size, simple structure, suspension installation, full use of plant space, and fast transportation. It is suitable for clothing, tobacco, medicine, cosmetics, food, publications, electronic manufacturing, e-commerce, new retail, omni-channel logistics centers, automated warehousing and other fields.

[0003] The existing hanging chain system (see the authorization announcement number CN 110712971 B hanging chain system and hanging chain control method, device and system) needs to transport the picking results to each packing port for packing. The packaged packages need to be transported to each waiting area according to the distribution area. The staff needs to continue to manually identify the waiting area of ​​the packages, classify the packages at the packing port, and use the cart to transport the classified packages to the waiting area. That is, the staff needs to keep going back and forth between the packing port and the waiting area. The workload of such staff will be very large, and the degree of automation is not high. A lot of information needs to be manually identified, which is easy to make mistakes. Even if the mode of transportation is changed to robot, it may cause the robot to collide with people frequently during transportation. Therefore, the "last mile" of the hanging chain system greatly increases the cost of transportation and sorting and reduces the efficiency of transportation and sorting. Summary of the invention

[0004] To this end, a hanging chain system is needed to solve the problem of high transportation and sorting costs and low transportation and sorting efficiency caused by the need for parcels at each packaging port to be manually sorted and transported to each transportation area.

[0005] To achieve the above object, the present invention provides a suspension chain system, which includes:

[0006] Several storage partitions, each of which stores goods of the same commodity category;

[0007] The main loop of the suspension chain and multiple branch loops of the suspension chain. There are connection points between the main loop of the suspension chain and the multiple branch loops of the suspension chain. The branch loops of the suspension chain convey the picking results of the corresponding storage areas in the warehouse to the main loop through the connection points.

[0008] The packing area is divided into several packing sub - areas according to the distribution areas. Each packing sub - area includes several sequentially arranged packing ports and a buffer plank road where the packing ports are connected to the main loop of the suspension chain.

[0009] The scheduling system includes a controller, sensors, a first identifier, a second identifier, and an operation panel. The operation panels are respectively arranged in each storage area. Each of the sensors is respectively arranged on the hanging device of the suspension chain, and the sensor provides the number of the hanging device. The first identifier is arranged at the connection point between the branch loop of the suspension chain and the main loop of the suspension chain, and is used to identify the sensor on the hanging device of the suspension chain. The second identifier is arranged at the connection point between the main loop of the suspension chain and the buffer plank road, and is used to identify the sensor on the hanging device of the suspension chain. The controller is electrically connected to the sensor, the first identifier, and the second identifier.

[0010] Further, the first identifier identifies the sensor to obtain the number of the hanging device and provides it to the controller. The controller connects the hanging device to the main loop of the suspension chain according to the number of the hanging device.

The controller judges whether to transfer the picking result on the hanging device to the buffer plank road according to the number of the hanging device.

[0011] Further, the controller decomposes the content of the order to generate an associated package, which includes: the numbers of each storage area, the quantity of goods in each storage area, and the number of the packing area.

[0068] See Figure 1 As shown, the present invention provides a suspension chain system, which includes several storage partitions 10, a main suspension chain loop 30, multiple suspension chain branch loops 20, a packing area and a scheduling system. The packing area is divided into several packing partitions 40 according to the distribution area. In each packing partition 40, several sequentially arranged packing ports 402 and a buffer passage 401 connecting the packing ports 402 to the main suspension chain loop 30 are provided; it is ensured that the distribution areas of each packing partition 40 are the same, there is no need for manual classification according to the distribution area, and there is no need to set up a waiting area for transportation. The packing partition 40 is equivalent to the waiting area for transportation, solving the "last mile" problem of the suspension chain system, greatly reducing the cost of conveying and sorting and improving the efficiency of conveying and sorting.

[0069] The implementation manner of the suspension chain system of the present invention is as follows:

[0070] A number of storage partitions 10, with goods of the same commodity category stored in each storage partition 10;

[0071] The main loop line 30 of the hanging chain and a number of branch loop lines 20 of the hanging chain. There is a connection point between the main loop line 30 of the hanging chain and the multiple branch loop lines 20 of the hanging chain. The branch loop lines 20 of the hanging chain transport the picking results corresponding to the storage partitions 10 in the warehouse to the main loop line through the connection point;

[0072] The packing area is divided into a number of packing partitions 40 according to the distribution areas. Each packing partition 40 includes a number of packing ports 402 arranged in sequence and a buffer walkway 401 where the packing ports 402 are connected to the main loop line 30 of the hanging chain;

[0073] The scheduling system, which includes a controller, sensors 60, a first identifier 50, a second identifier 70, and an operation panel 101; the operation panel 101 is respectively arranged in each storage partition 10; each of the sensors 60 is respectively arranged on the hanging device 201 of the hanging chain, and the sensor 60 provides the number of the hanging device 201; the first identifier 50 is arranged at the connection point between the branch loop line 20 of the hanging chain and the main loop line 30 of the hanging chain, and is used to identify the sensor 60 on the hanging device 201 of the hanging chain; the second identifier 70 is arranged at the connection point between the main loop line 30 of the hanging chain and the buffer walkway 401, and is used to identify the sensor 60 on the hanging device 201 of the hanging chain. The controller is electrically connected to the sensor 60, the first identifier 50, and the second identifier 70. The above-mentioned multiple branch loop lines 20 of the hanging chain are equipped with hanging devices 201, and the main loop line 30 of the hanging chain is not equipped with hanging devices 201. The sensor 60 on each hanging device 201 can be a sensor 60 with RFID, which is used to identify the number of the hanging device 201 for the task and the subordinate branch loop line 20 of the hanging chain, so as to ensure an efficient picking process. In addition, the controller is used to instruct the coordinated operation between the above different components to ensure the coordinated operation of the hanging chain system.

[0074] The controller is used to instruct the coordinated operation between the above different components. Specifically, the controller decomposes the content of the order to generate an associated package, and the associated package includes: the numbers of each storage partition 10, the quantities of goods in each storage partition 10, and the numbers of the packing partitions 40;

[0075] Such as the associated package ()

[0076] {Goods *i in storage partition 10001;

[0077] Goods *i in storage partition 10002;

[0078] …

[0079] Goods *j in storage partition 10n;

[0080] Packaging partition 40k;

[0081] }; where n represents the partition number, i and j both represent the quantity of goods, and k represents the number of the 40th packaging partition;

[0082] The controller transmits the number of goods in the storage partition 10 to the operation panel 101 of the corresponding storage partition 10 according to the number of each storage partition 10 and displays it. The picking staff picks the goods according to the number of goods displayed on the operation panel 101, puts the picked goods on the idle mounting device 201, and then inputs the picking result and the number of the mounting device 201 into the operation panel 101, which transmits it to the controller. The controller switches the mounting device 201 from the idle state to the occupied state, and determines whether the picking result is equal to the number of goods in the storage partition 10. If it is equal, it is marked as qualified for picking, and if it is not equal, it is marked as unqualified for picking, and the picking staff will pick again for verification. The first identifier 50 identifies the sensor 60 to obtain the number of the mounting device 201 and provides it to the controller; the controller determines whether to connect the mounting device 201 to the main loop line 30 of the suspension chain according to the number of the mounting device 201; it mainly determines whether the mounting device 201 is in an occupied state and the picking is qualified. If both are satisfied, the mounting device 201 is connected to the main loop line 30 of the suspension chain. The second identifier 70 identifies the sensor 60 to obtain the number of the mounting device 201 and provides it to the controller. The controller determines whether to transfer the picking result on the mounting device 201 to the buffer stack 401 according to the number of the mounting device 201; it mainly determines whether the mounting device 201 is assigned to the packaging port 402 of the second identifier 70 for packaging. If so, the picking result on the mounting device 201 is transferred to the buffer stack 401. The preferred controller transfers the picking results of several mounting devices 201 of the same associated package to the buffer stacker 401 in sequence according to the number of the mounting device 201 of the second identifier 70, and packs them at the packing port 402, which is convenient for the staff to pack or the packing machine to pack. The buffer stacker 401 can be a slideway or a belt conveyor, which is used to transport the picking results transported on the main loop line to the corresponding packing port; each buffer stacker 401 is provided with a corresponding control device 80 (this is the prior art) and a valve of the control device 80, and the valve is electrically connected to the controller, that is, the controller controls the valve so that the picking results on the mounting device 201 are transferred to the buffer stacker 401 through the control device 80. If it is a slideway, the picking results of several mounting devices 201 of the same associated package are transferred to the slideway in sequence. At this time, the slideway state is occupied. When all the picking results of the associated package slide to the bottom of the slideway, the slideway is packed, and the slideway is idle after the packing is completed; the next round of packing can be carried out. The slideway type can solve the problem of different heights between the packing place and the hanging chain.When it is a belt conveyor, the picking results of several hanging devices 201 in the same associated package are successively transferred to the belt conveyor. At this time, the belt conveyor pauses transportation until all the picking structures of the associated package are transferred to the belt conveyor. Then the belt conveyor transports a certain distance (with intervals formed between the associated packages for easy distinction and packing), waiting for the transfer of the next associated package. The belt conveyor follows the principle of first-in, first-packed, that is, after the previous associated package is packed into a package, the belt conveyor transports the next associated package to the packing port 402 for packing. The belt conveyor can arrange multiple consecutive associated packages so that the same associated package does not need to wait on the main loop line 30 of the hanging chain. Of course, a chute and a belt conveyor can also be set at the same time to combine the advantages of both.

[0083] See Figure 2 As shown, a scheduling method for a hanging chain system, which applies the above-mentioned hanging chain system, includes the following steps:

[0084] S1. The controller decomposes the content of the order to generate an associated package, which includes: the numbers of each storage area 10, the quantities of goods in each storage area 10, and the number of the packing area 40;

[0085] S2. The controller transmits the quantity of goods in the storage area 10 to the operation panel 101 corresponding to the storage area 10 according to the number of each storage area 10 and displays it;

[0086] S3. According to the quantity of goods in the storage area 10 displayed on the operation panel 101 in the storage area 10, corresponding picking is carried out, and the picking result is placed into the hanging device 201. The controller switches the state of the hanging device 201 and judges whether the picking is qualified according to the picking result;

[0087] S4. The first identifier 50 identifies the number of the hanging device 201 obtained by the sensor 60 on the branch loop line 20 of the hanging chain and provides it to the controller; the controller judges whether to connect the hanging device 201 to the main loop line 30 of the hanging chain according to the number of the hanging device 201;

[0088] S5. The controller traverses several buffer gangways 401 in the packing area 40 according to the number of the packing area 40 in the associated package to obtain the number of the packing port 402;

[0089] S6. The second identifier 70 identifies the number of the hanging device 201 obtained by the sensor 60 and provides it to the controller. The controller judges whether it matches the number of the packing port 402 of the second identifier according to the number of the hanging device 201 and decides whether to transfer the picking result on the hanging device 201 to the buffer gangway 401.

[0090] The specific steps of step S3 include the following steps:

[0092] S32. Transmit the picking result and the number of the mounting device 201 to the controller through the operation panel 101;

[0093] S33. The controller switches the mounting device 201 to the occupied state, and determines whether the picking result is equal to the quantity of goods in the storage partition 10. If the picking result is equal to the quantity of goods in the storage partition 10, it is determined that the picking is qualified; otherwise, it is determined that the picking is unqualified, and picking is performed again according to the quantity of goods in the storage partition 10.

[0094] The step S4 specifically includes the following steps:

[0095] S41. The first identifier 50 identifies the sensor 60 of the mounting device 201 on the hanging chain branch loop 20 to obtain the number of the mounting device 201, and provides the number of the mounting device 201 to the controller;

[0096] S42. The controller determines whether the state of the mounting device 201 is the occupied state according to the number of the mounting device 201. If the state of the mounting device 201 is the occupied state, step S43 is performed; otherwise, the mounting device 201 is not connected to the hanging chain main loop 30;

[0097] S43. The controller determines whether the picking of the mounting device 201 is qualified according to the number of the mounting device 201. If the picking is qualified, the mounting device 201 is connected to the hanging chain main loop 30; otherwise, it is not connected.

[0098] When the step S5 is applied to the chute - type buffer plank road 401, it specifically includes the following steps:

[0099] S51. The controller determines whether the associated package of the number of the mounting device 201 is assigned the number of the packing port 402. If it is not assigned, S52 is performed; if it is already assigned, step S6 is entered;

[0100] S52. The controller traverses all the buffer plank roads 401 of the packing ports 402 in the packing partition 40 according to the packing partition 40 number in the associated package. If there is an idle buffer plank road 401, the number of the packing port 402 of the buffer plank road 401 is obtained. If there is no idle buffer plank road 401, the associated package enters the waiting - for - assignment state. When there is an idle buffer plank road 401 in the packing partition 40, the number of the packing port 402 of the buffer plank road 401 is preferentially obtained;

[0101] S53. The controller assigns the numbers of all the mounting devices 201 of the associated package to the packing port 402. When the step S5 is applied to the belt conveyor type buffer walkway 401, it specifically includes the following steps:

[0102] S51. The controller determines whether the associated package with the number of the mounting device 201 is assigned the number of the packing port 402. If not, go to S52; if so, enter step S6;

[0103] S52. The controller traverses the buffer walkways 401 of all the packing ports 402 in the packing partition 40 according to the number of the packing partition 40 in the associated package, and obtains the occupancy of the buffer walkways 401 of all the packing ports 402 in the packing partition 40;

[0104] S53. Compare the occupancy of the buffer walkways 401 of all the packing ports 402, and obtain the number of the packing port 402 of the buffer walkway 401 with the minimum occupancy;

[0105] S54. The controller assigns the numbers of all the mounting devices 201 of the associated package to the packing port 402.

[0106] The step S6 specifically includes the following steps:

[0108] S62. The controller determines whether the mounting device 201 is assigned to the packing port 402 for packing according to the number of the mounting device 201.
