Technical Field

[0001] The present application belongs to the technical field of cargo transportation, and in particular relates to a method and device for allocating pallets out of a stereoscopic warehouse. Background Art

[0002] As a warehouse that uses high-rise shelves and automated control equipment to transport goods, a high-bay warehouse can store and retrieve goods by loading pallets on them. Generally speaking, a high-bay warehouse uses a conveyor line system, such as multiple lanes, rollers or chains, to sequentially transport pallets from the storage location to the picking area or loading area.

[0003] However, this method of using the conveyor line system to remove pallets from the warehouse requires manual placement of pallets loaded with goods on the aisles one by one until the number of pallets transported by all aisles reaches the number of pallets to be removed from the warehouse. This not only requires warehouse personnel to invest a lot of working time, but also fails to guarantee the overall efficiency of pallet removal. Summary of the invention

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0019] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0020] See also Figure 1 , Figure 1 An overall flow chart of a pallet outbound allocation method for a stereoscopic warehouse provided in an embodiment of the present application is shown.

[0021] like Figure 1 As shown, the pallet outbound distribution method of the stereoscopic warehouse may at least include the following steps: Step 102: After receiving the number of outbound pallets, the number of in-stock pallets is divided based on the number of outbound pallets to obtain a first element set.

[0022] In the embodiment of the present application, the pallet outbound allocation method of the stereoscopic warehouse can be, but is not limited to, applied to the management terminal of the stereoscopic warehouse. The management terminal can establish a connection with the conveying system (for example, including multiple lanes, rollers or chains) in the stereoscopic warehouse to control multiple lanes to perform pallet outbound processing according to the number of outbound pallets input by the user and the number of in-stock pallets in the stereoscopic warehouse. Here, the management terminal can be provided with an interactive interface to display the current lane working status to the warehouse personnel. In addition, it can also receive the number of outbound pallets input by the warehouse personnel, and display the number of pallets corresponding to each lane to the warehouse personnel after generating the corresponding pallet allocation combination. It can be understood that the pallet allocation combination can be understood as the number of pallets corresponding to multiple lanes arranged in a specified order. For example, but not limited to, when the pallet allocation combination is represented as (1, 3), it can be represented that the number of pallets transported by the first lane when performing the pallet outbound processing is 1, and the number of pallets transported by the second lane when performing the pallet outbound processing is 3, and before the pallet outbound processing is performed, it is also necessary to ensure that the warehouse personnel place the corresponding number of pallets at the entrance of the lane.

[0023] Of course, the management terminal in the embodiment of the present application can also establish connections with the automatic guided vehicle, the shelf system and the barcode system to achieve all-round control of the three-dimensional warehouse, but will not go into details here.

[0024] It can also be understood that the management terminal can divide the number of in-stock pallets in the stereoscopic warehouse by combining the number of received outbound pallets, so as to screen out multiple first elements as initial elements from the divided first element set, and determine whether each initial element has a second element set; then, when it is detected that any initial element has a second element set, multiple second elements can be screened out in the corresponding second element set, so as to determine the pallet allocation combination that meets the lane allocation conditions based on all second elements, the corresponding initial elements and the preset number of lanes, so as to facilitate warehouse personnel to deploy the corresponding number of pallets in each lane in advance according to the pallet allocation combination, which not only reduces the working time invested by warehouse personnel, but also effectively ensures the overall outbound efficiency of pallets.

[0025] Specifically, when performing pallet outbound allocation processing on the high-bay warehouse, the management terminal can, but is not limited to, obtain the number of outbound pallets input by the warehouse personnel through the interactive interface mentioned above, and determine whether the pallet outbound processing can be performed normally in combination with the working status of all lanes and the number of pallets in stock. For example, but not limited to, when the number of all lanes in a non-working state exceeds the preset number of lanes, and the number of pallets in stock is greater than or equal to the number of outbound pallets, it is determined that the pallet outbound processing can be performed normally; when the number of all lanes in a non-working state does not exceed the preset number of lanes, it is determined that the pallet outbound processing cannot be performed normally temporarily; when the number of pallets in stock is less than the number of outbound pallets, it is determined that the pallet outbound processing cannot be performed normally temporarily, and it is not limited to this.

[0026] Furthermore, after determining that the pallet outbound processing can be carried out normally, the management terminal can randomly divide the number of pallets in stock based on the number of outbound pallets to obtain a first element set containing multiple first elements. Here, the first element can be understood as the number of pallets required to be deployed in a single lane (the number of first elements must be greater than or equal to 3), each first element is less than the number of outbound pallets input by the warehouse staff, and the sum of all first elements is equal to the number of pallets in stock. It can be understood that the number of pallets in stock can be divided by a random number allocation algorithm, but is not limited to it. For example, when the number of pallets in stock is 5, the obtained first element set can be (1, 1, 3), that is, the three first elements are 1, 1 and 3 respectively. Of course, a first element set represented as (1, 2, 2) can also be obtained, but it is not limited to this.

[0027] As an option of the embodiment of the present application, the number of pallets in stock is divided based on the number of pallets out of the warehouse to obtain a first element set, including: The number of pallets in stock is divided based on a preset number of elements to obtain a third element set; wherein the number of all third elements included in the third element set is the same as the preset number of elements, and the sum of all third elements is equal to the number of pallets in stock; When each third element in the third element set is less than the number of outbound pallets, the third element set is used as the first element set; or When any third element in the third element set is greater than or equal to the number of outbound pallets, the third element is divided into at least two sub-elements, and the third element set is updated based on all the sub-elements; The updated third element set is used as the first element set.

[0028] Specifically, when obtaining the first element set, the management terminal can also substitute the preset number of elements and the number of pallets in stock into the random number allocation algorithm to obtain a third element set containing multiple third elements. The third element can be understood as the number of pallets required to be deployed in a single aisle. The sum of all third elements is equal to the number of pallets in stock. When it is detected that any third element is less than the number of pallets out of the warehouse, it indicates that the current third element set meets the requirements, and then the third element set can be used as the first element set, and each third element in the third element set is used as the first element.

[0029] When it is detected that any third element is greater than or equal to the number of outbound pallets, it indicates that the current set of third elements does not meet the requirements, and the third element can be randomly divided into multiple sub-elements. When each sub-element is less than the number of outbound pallets, the set of third elements is updated so that the corresponding third element is updated to multiple sub-elements.

[0030] Next, the updated third element set may be used as the first element set, and each third element in the third element set may be used as the first element.

[0031] Of course, in the embodiment of the present application, when it is detected that any third element is greater than or equal to the number of outbound pallets, the preset number of elements and the number of in-stock pallets can be substituted into the random number allocation algorithm again to obtain a third element set containing multiple third elements and determine whether the recovered third element set meets the requirements. This is not limited to this.

[0032] Step 104: select at least two first elements from the first element set as initial elements, and determine whether each initial element exists in the second element set.

[0033] Specifically, after obtaining the first element set, the management terminal may, but is not limited to, randomly select multiple first elements from the first element set as initial elements to determine whether each initial element has a second element set that can be combined. Here, the second element set may include one or more second elements, each second element may be understood as the number of pallets required to be deployed in a single lane, and each second element is any first element in the first element set excluding the corresponding initial element.

[0034] As another option of the embodiment of the present application, selecting at least two first elements from the first element set as initial elements includes: Determine all the different first elements in the first element set; At least two first elements are selected from all different first elements as initial elements.

[0035] Specifically, in order to ensure the efficiency of generating the pallet allocation combination, the management terminal may also determine all different first elements in all the first element sets, and may randomly select multiple first elements from all the different first elements as initial elements. For example, taking the first element set mentioned above as (1, 1, 3), all the different first elements determined are 1 and 3, and all the initial elements selected are also 1 and 3.

[0036] It is understandable that the embodiment of the present application can also use all different first elements as initial elements, and is not limited to this.

[0037] As another option of the embodiment of the present application, determining whether each initial element has a second element set includes: When at least one first element is detected in the first element set that is greater than or equal to any initial element, it is determined that the corresponding initial element exists in the second element set, and the second element set is obtained based on all first elements greater than or equal to the initial element; or When any first element detected in the first element set is smaller than any initial element, it is determined that the corresponding initial element does not exist in the second element set.

[0038] Specifically, when determining whether there is a second element set for each initial element, the management terminal can also determine whether there are one or more first elements in the first element set that are greater than any initial element, and when it is detected that there are one or more first elements greater than or equal to a certain initial element, it can be determined that the initial element has a second element set, and the set of all first elements greater than or equal to the initial element can be used as the second element set. For example, taking the first element set as the above-mentioned (1, 1, 3) as an example, when the initial element is 1, since the other first elements 1 and 3 are greater than or equal to the initial element, it can be determined that the initial element has a second element set, and the second element set can be expressed as (1, 3).

[0039] It is understandable that when it is detected that there are one or more first elements that are smaller than a certain initial element, it can be determined that the initial element does not exist in the second element set. Since each first element in the first element set is smaller than the number of pallets to be shipped out, the final pallet allocation combination cannot be obtained based on the initial element. For example, still taking the first element set as the above-mentioned (1, 1, 3) as an example, when the initial element is 3, since other first element sets are smaller than the initial element, it can be determined that the initial element does not exist in the second element set.

[0040] Step 106: When it is detected that any initial element has a second element set, at least two second elements are selected from the second element set, and a pallet allocation combination is determined based on all the second elements, the initial elements and the preset number of lanes.

[0041] Specifically, after determining that one or more initial elements exist in a second element set, the management terminal can, but is not limited to, randomly select multiple second elements (or all second elements) from the second element set corresponding to each initial element, and determine whether the pallet allocation combination composed of each initial element and each corresponding second element meets the requirements for outbound pallets by summing each initial element and each corresponding second element. Furthermore, it can be determined whether the composed pallet allocation combination can be executed normally in combination with the preset number of lanes, so that if it is determined that it can be executed normally, the corresponding pallet allocation combination can be displayed to the warehouse personnel, so that the warehouse personnel can deploy the corresponding number of pallets in each lane in advance according to the pallet allocation combination, which not only reduces the working time invested by the warehouse personnel, but also effectively ensures the overall outbound efficiency of the pallets.

[0042] Here, the preset number of lanes may be, but is not limited to, determined according to the working state of each lane. For example, the number of all lanes that are currently not in working state may be used as the preset number of lanes, but is not limited thereto.

[0043] As another option of the embodiment of the present application, a pallet allocation combination is determined according to all second elements, initial elements and a preset number of lanes, including: Each second element is summed with the initial element to obtain a corresponding first summation result; When it is detected that any first sum result is less than the number of outbound pallets, at least one second element is selected from the second element set as a combination element; Each combination element and the summation result are summed up respectively to obtain a corresponding second summation result, and when it is detected that any second summation result is equal to the number of outbound pallets, it is determined whether the number of lanes corresponding to the second summation result is less than or equal to the preset number of lanes; When the number of lanes corresponding to the second summation result is less than or equal to the preset number of lanes, the pallet allocation combination is determined according to the combination element corresponding to the second summation result, the second element and the initial element.

[0044] Specifically, when determining the pallet allocation combination, the management terminal may perform a summation process on each initial element and each corresponding second element respectively to obtain a corresponding first summation result.

[0045] It can be understood that when it is detected that any first summation result is less than the number of outbound pallets, it indicates that the pallet allocation combination consisting of the initial element and the second element corresponding to the first summation result has not yet met the outbound pallet requirements, and then the second element set corresponding to the initial element can be eliminated to eliminate the second element corresponding to the first summation result, and at least one second element is randomly selected from the second element set after the elimination process as a combination element, and the first summation result is summed up through each combination element to obtain the corresponding second summation result.

[0046] Next, when it is detected that any second summation result is equal to the number of pallets to be shipped out, it indicates that the pallet allocation combination consisting of the initial element, the second element and the combination element corresponding to the second summation result meets the demand for pallets to be shipped out, and then it can be determined whether the number of lanes corresponding to the second summation result is less than or equal to the preset number of lanes. Here, the number of lanes corresponding to the second summation result is the same as the number of elements corresponding to it. For example, the second summation result here includes the second element, the initial element and the combination element, that is, the number of lanes corresponding to the second summation result is three. It should be noted that when any second summation result is less than the number of pallets to be shipped out, at least one second element can be selected from the set of second elements after elimination again in the above manner as a combination element, and each combination element obtained at this time is summed with the corresponding second summation result until the final summation result is greater than or equal to the number of pallets to be shipped out; when any second summation result is greater than the number of pallets to be shipped out, it indicates that the pallet allocation combination consisting of the initial element, the second element and the combination element corresponding to the second summation result does not meet the demand for pallets to be shipped out.

[0047] When the number of lanes corresponding to the second summation result is less than or equal to the preset number of lanes, it indicates that the pallet allocation combination composed of the second summation result can be executed normally, and then the initial element, the second element and the combination element corresponding to the second summation result can be used as the pallet allocation combination to be displayed to the warehouse staff. It should be noted that when the number of lanes corresponding to the second summation result is greater than the preset number of lanes, it indicates that the pallet allocation combination composed of the second summation result cannot be executed normally, and then the number of pallets in the warehouse needs to be divided again based on the number of pallets out of the warehouse, that is, the first element set is re-determined, and the pallet allocation combination that can be executed normally can be determined by referring to one or more of the above-mentioned embodiments, but it will not be repeated here.

[0048] It should be noted that warehouse personnel need to deploy the corresponding number of pallets in each aisle in sequence according to the order of elements of the pallet allocation combination. For example, the first aisle should be deployed with the same number of pallets as the initial element, the second aisle should be deployed with the same number of pallets as the second element, and the third aisle should be deployed with the same number of pallets as the combination element. The aisle arrangement is not limited to the one here.

[0049] It can also be understood that when it is detected that any first summation result is equal to the number of outbound pallets, it indicates that the pallet allocation combination composed of the initial element and the second element corresponding to the first summation result meets the outbound pallet demand, and then it can be determined whether the number of lanes corresponding to the first summation result is less than or equal to the preset number of lanes. Here, the number of lanes corresponding to the first summation result is the same as the number of elements corresponding to it. For example, the first summation result here includes the second element and the initial element, that is, the number of lanes corresponding to the first summation result is two.

[0050] Next, when the number of lanes corresponding to the first summation result is less than or equal to the preset number of lanes, it indicates that the pallet allocation combination composed of the first summation result can be executed normally, and then the initial element and the second element corresponding to the first summation result in sequence can be used as the pallet allocation combination to be displayed to the warehouse staff. It should be noted that when the number of lanes corresponding to the first summation result is greater than the preset number of lanes, it indicates that the pallet allocation combination composed of the first summation result cannot be executed normally, and then the number of pallets in stock needs to be divided again based on the number of pallets out of the warehouse, that is, the first element set is re-determined, and one or more of the above-mentioned embodiments can be referred to to determine the pallet allocation combination that can be executed normally, but no further details are given here.

[0051] It can also be understood that when it is detected that any one of the first summation results is greater than the number of outbound pallets, it indicates that the pallet allocation combination composed of the initial element corresponding to the first summation result and the second element does not meet the outbound pallet requirements, and then the number of in-stock pallets needs to be divided again based on the number of outbound pallets to obtain the fourth element set (that is, the first element set is re-determined), and the pallet allocation combination that can be executed normally can be determined by referring to one or more of the above-mentioned embodiments, but no further details will be given here.

[0052] As another option of the embodiment of the present application, after determining the pallet allocation combination according to all the second elements, the initial elements and the preset number of lanes, the method further includes: When it is detected that there are at least two pallet allocation combinations, the corresponding pallet assembly time is obtained according to the preset lane assembly time and each pallet allocation combination; From all pallet allocation combinations, select the pallet allocation combination corresponding to the minimum pallet assembly time.

[0053] Specifically, since different first element sets may determine pallet allocation combinations, when the management terminal detects that there are multiple pallet allocation combinations, in order to determine the optimal pallet allocation combination, it is also possible to calculate the time spent by warehouse personnel in assembling and deploying pallets according to each pallet allocation combination based on the preset aisle assembly time and each pallet allocation combination, that is, the pallet assembly time, and use the pallet allocation combination corresponding to the minimum pallet assembly time as the final determined pallet allocation combination to ensure that the working time invested by warehouse personnel is minimized.

[0054] Here, when calculating the pallet assembly time corresponding to each pallet allocation combination, the corresponding lane number that is not in operation can be determined based on the number of lanes corresponding to each pallet allocation combination, but is not limited to it. Then, the preset lane assembly time corresponding to each lane number and the number of pallets (that is, the corresponding element) can be multiplied, and the product results of all lane numbers can be summed to obtain the pallet assembly time of the corresponding pallet allocation combination, and it is not limited to this.

[0055] Also see here Figure 2 The schematic flow chart of a method for allocating pallets out of a stereoscopic warehouse provided by an embodiment of the present application is shown as follows: Figure 2 As shown, when the first element set is (1, 1, 3) and the number of outbound pallets is 4, the first element represented by 1 and the first element represented by 3 can be selected from the first element set as initial elements, wherein the second element set corresponding to the initial element represented by 1 is (1, 3), and the initial element represented by 3 does not exist in the second element set.

[0056] Next, the second element represented by 1 and the second element represented by 3 can be screened out in the second element set corresponding to the initial element represented by 1, wherein the sum of the initial element represented by 1 and the second element represented by 1 is less than 4, and the second element represented by 3 can be determined as the combination element in the second element set; the sum of the initial element represented by 1 and the second element represented by 3 is equal to 4, which meets the demand for outbound pallets, and can be recorded as a pallet allocation combination (since the number of elements is only 2, the comparison process with the preset number of lanes is omitted here).

[0057] Next, the sum of the initial element represented by 1, the second element represented by 1, and the combined element represented by 3 is greater than 4, which cannot meet the outbound pallet demand.
