Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The replenishment method for the sorting and stocking area provided by the embodiment can be used in a tobacco logistics system for replenishing tobacco on a sorting line. As shown in fig. 1, the tobacco logistics system comprises a warehouse, a sorting stock area, a cache replenishment line and a sorting line:
warehouse: the cigarette sorting machine is used for storing cigarettes, a common warehouse is a warehouse and is a vertical warehouse, the cigarettes are stored in the vertical warehouse according to the mode of a whole case of cigarettes, the whole case of cigarettes is also called cigarette pieces, one case of cigarettes comprises a plurality of cigarettes according to specifications, and on a sorting line, the whole case of cigarettes is unpacked and split into a plurality of cigarettes and then sorted according to an order. In the warehouse, whole case cigarette is deposited on goods shelves, is provided with arm, turnover dolly and robot etc. in the warehouse, can snatch whole case's piece cigarette in the position that corresponds as required, carries the entrance of letter sorting spare area.
Sorting and preparing goods area: because the cigarette in the storage vertical warehouse is deposited densely, be unfavorable for taking in real time, especially to high-speed letter sorting line, the volume of letter sorting goods is big in the unit interval, and the shipment in the storage vertical warehouse can't satisfy the demand of high-speed letter sorting, consequently sets up letter sorting stock area, provides the cigarette of letter sorting for high-speed moving letter sorting line. A plurality of stock channels are arranged in the sorting stock area, and cigarette pieces fed from an inlet of the sorting stock area enter each stock channel. Cigarettes of one type are conveyed in one stock channel, and cigarettes with larger demand quantity can also be conveyed through a plurality of stock channels. The whole boxes of cigarettes to be sorted are input into the sorting line through the sorting standby area, so that the sorting line can conveniently sort the cigarettes in real time.
Caching a replenishment line: for the cigarette pieces conveyed from the sorting stock area, the cigarette pieces are waiting for sorting on the buffer replenishment line before entering the sorting line.
Sorting line: the cigarette sorting line is used for unpacking the conveyed cigarette packs, the number of the whole cigarette packs is large, the types of cigarettes contained in a general order are more, but the number of the cigarettes cannot reach the number of the whole cigarette packs, so that the cigarette packs can be unpacked and divided into one cigarette strip on the sorting line, then the required cigarette strip is sorted according to the requirement of the order, and then the cigarette strip is packed, so that subsequent distribution is facilitated.
The replenishment method for the sorting stock area provided in this embodiment is used in the sorting stock area, a plurality of stock channels for transporting the items are provided in the sorting stock area, an inlet of the sorting stock area is connected to a warehouse, the required items are obtained from the warehouse, an outlet of the sorting stock area is connected to a sorting line through a cache stock replenishment line, the sorting line sorts the items according to orders, and the replenishment method includes the following steps, as shown in fig. 2:
s1: and acquiring the quantity of goods in each stock channel, and initiating the replenishment request of the goods when the quantity of the goods is less than a preset replenishment threshold value.
In the sorting and stocking-up area, each goods is sent into the cache replenishment line through the stocking-up channel and then enters the sorting line. The cigarette carton of a variety can occupy one or more stock passageways and carry, according to the demand of letter sorting line, sets up. For example, two or three stock channels may be provided for the cigarette types requiring greater quantities. Along with the going on of letter sorting task on the letter sorting line, constantly there is goods to be sent out the letter sorting line by the packing after letter sorting, goods in the letter sorting passageway also can constantly get into buffer memory replenishment line and letter sorting line, consequently the quantity of letter sorting stock district interior piece cigarette can reduce gradually. And when the quantity of the goods is less than the preset replenishment threshold value, initiating a replenishment request of the goods. For example, in the stock passage of the south-central sea brand cigarette, when the number of cigarette pieces is less than 20, a replenishment request is initiated.
The preset replenishment threshold value here may be set to a fixed value, for example, to 10 or 20 or 30, etc., depending on the situation. As a further embodiment, each variety of cigarettes may correspond to a different preset restocking threshold set according to the total amount of its corresponding variety of cigarettes in the sorting order of the day. The larger the total amount of the cigarettes in the sorting order on the day is, the higher the corresponding preset replenishment threshold value is. For example, the south-central sea brand cigarette has the largest total amount in the current day sort order, the preset replenishment threshold for the south-central sea brand cigarette is set to 30, while the yellow crane tower cigarette has the smaller total amount in the current day sort order, and the preset replenishment threshold for the yellow crane tower cigarette is set to 15. In this way, the preset restocking threshold corresponding to this brand of cigarettes is set according to the size of the total amount in the sorting order of the day. Like this, to the great tobacco product of demand, improve its quantity of supplementing, in time supplement its quantity, guarantee that the tobacco product quantity of large demand is sufficient, the normal work of letter sorting line of being convenient for.
S2: the replenishment requests of the plurality of goods which have been initiated are acquired within a preset time period. Since the number of the goods in the different stock passage is decreased as the sorting work of the production line is performed, the replenishment request is sequentially generated according to the rule of S1. Within a time period, multiple replenishment requests may be generated. The time period set here is set empirically and can be set, for example, to 5 to 15 minutes, for example, to 6 minutes, 8 minutes, 10 minutes or 12 minutes. By reasonably collecting replenishment requests in one period, the replenishment requests are replenished according to the priority.
S3: for each item requiring replenishment, the priority of the replenishment request for each item is calculated. Because a plurality of replenishment requests are initiated in one period, but replenishment needs to be carried out successively, the urgency degree of the replenishment requests is distinguished, and reasonable replenishment is carried out, so that the method is an effective way for optimizing resource utilization.
In the scheme, the priority of the replenishment request of each cigarette variety is calculated, and the specific calculation mode of the priority is as follows for the replenishment request of one cigarette variety:
firstly, calculating the time tn required by the variety of cigarettes from the initiation of a replenishment request to a warehouse to the completion of replenishment through historical data; tn here is the time required for completion of replenishment predicted from previous historical data, and this time is known from previous replenishment experience, from the time when a replenishment request is made to the warehouse, to the time when the warehouse responds to the request to replenish the sorted stock area with cigarettes of the variety to which the response is made.
Then, the current time t to the time t + tn are obtained, and the quantity of the cigarette of the variety required on the sorting line in the time period is a. When the sorting line works normally, the tasks of order sorting completed within a period of time can be predicted, and the quantity of the cigarette of the variety required in the tasks can also be predicted, so that the quantity a of the cigarette of the variety required on the sorting line from the current time t to the time t + tn can be obtained.
The replenishment quantity of the cigarette of the variety is m, the replenishment quantity is reasonably set according to the upper limit and the lower limit of the content of the stock channel, and the replenishment quantity is increased if replenishment is completed after a replenishment request is initiated.
The stock quantity of the cigarette of the variety in the sorting and stocking area is n, wherein n refers to the stock of the cigarette of the variety in the sorting and stocking area, and the stock can be the residual stock in the current stocking channel. If a cigarette of that type is transported through a plurality of stock aisles, one or more of which initiate a restocking request, the inventory count includes the inventory of that type of cigarette in all of its stock aisles.
The quantity of the goods on the cache replenishment line is l, wherein l refers to the quantity of the cigarettes of the variety which do not enter the sorting line on the cache replenishment line.
After the parameter information is obtained, the priority of the replenishment request of the cigarette of the variety is calculated,
if a is more than or equal to m + n + l, the priority of the replenishment request of the goods is one level. In this case, it is explained that, even after replenishment is performed according to the replenishment request, the required quantity of the cigarette of the type in the time period is still larger than the replenishment quantity plus the original stock quantity and the unsorted stock quantity, and it is explained that the required quantity of the cigarette of the type on the sorting line cannot be satisfied even after completion of replenishment, and therefore the replenishment request is very urgent and the priority is highest.
If n + l < a < m + n + l, the replenishment request for the item has a second priority. In this case, the demand in the time period is larger than the stock quantity of the current stock area and the unsorted archive, but if the quantity requirement can be met after the replenishment, the urgency degree of the replenishment request is second to the first, and the priority is second.
If a is less than or equal to n + l, the priority of the replenishment request of the goods is three levels; in this case, the cigarette demand of the variety in the replenishment time period is smaller than the sum of the current stock and the unsorted quantity, and the urgency degree of the replenishment request is second to third, which is the priority.
In addition, the priority of the current replenishment request can be determined according to the quantity of the goods required by the remaining sorting tasks, wherein the quantity of the goods required by the remaining sorting tasks is the quantity of the cigarettes of the variety required when all orders are sorted, if the quantity of the cigarettes of the variety required is less than m + n + l, all the cigarettes after replenishment can meet the requirements of all the remaining orders, at the moment, the replenishment urgency degree is low, and the priority of the replenishment tasks of the goods is four.
According to the principle, the priority is calculated for all replenishment requests received in the time period, so that all replenishment priorities for initiating replenishment requests can be obtained.
S4: and sending the replenishment request of the goods to the warehouse according to the priority. Therefore, the vertical warehouse can supplement the goods from small to large according to the priority. According to the calculation, the smaller the priority is, the more urgent the replenishment request is, and therefore replenishment is performed in the order of the priority from small to large.
And (4) performing secondary sequencing on the replenishment requests of different cigarettes belonging to the same priority level according to the replenishment positions in the current time period. Because the replenishment has a default replenishment sequence related to the position, if the replenishment belongs to the same priority level, the replenishment is carried out according to the position, which is beneficial to improving the resource utilization rate and ensuring the optimal replenishment speed.
Under the condition that the replenishment requests are more, the top n replenishment requests which are sequenced in the front can be selected after the replenishment requests are sequenced according to the priority, so that the replenishment demands are sent to the elevated vertical warehouse regularly and quantitatively for replenishment. N here is set reasonably as required. After receiving the replenishment requests, the elevated warehouse transfers mechanical arms, turnover trolleys or robots at corresponding positions, and the cigarettes corresponding to the replenishment requests are conveyed to an entrance of a sorting and stocking area according to the replenishment quantity, so that the automatic replenishment process is realized.
The replenishment method for the sorting stock area is particularly suitable for a sorting line running at a high speed, firstly, a plurality of replenishment requests in a period of time are obtained, the priority of the replenishment requests is calculated, and therefore the most urgent replenishment request is found. For the sorting line running at high speed, the method can quickly and effectively carry out replenishment, thereby providing sufficient sorted goods for the sorting line running at high speed and ensuring the normal running of the high-speed sorting line. This has solved letter sorting stock district and has adopted the inconsistent problem of traditional benefit goods mode and the actual benefit goods demand of letter sorting line to avoided the problem that the short-order was shut down on the high-speed letter sorting in-process letter sorting line, promoted sorting efficiency.
