Description

An unmanned convenience food sales system that determines the appropriate ordering time for each convenience food item

[0001] The present invention relates to an unmanned convenience food sales technology that calculates the expected sales rate for each convenience food and determines an appropriate ordering time for each convenience food based on the calculated expected sales rate.

[0002]

[0003] In response to the modern need to easily consume the food they desire, the demand for convenient ready-to-eat foods, which are easy to store and can be conveniently prepared using heating methods such as microwave ovens, is rapidly increasing.

[0004] These ready-to-eat foods were generally sold by being placed in refrigerators or freezers in supermarkets or convenience stores, but recently, sales are also taking place through unmanned stores and vending machines, which can reduce labor costs compared to existing manned stores.

[0005] However, in the case of selling ready-to-eat foods using such unmanned vending machines, it is difficult to expect management at the same level through personnel as in existing manned or unmanned stores, where employees immediately check products and quantities. Consequently, there was a problem in that it was difficult to individually check ready-to-eat foods that required additional orders due to high sales volume or those that did not require orders due to sluggish sales.

[0006] As part of an effort to solve these problems, Korean Registered Patent Publication No. 10-136338 (Application Date: August 23, 2019; Publication Date: July 21, 2020; hereinafter referred to as the "prior art") disclosed a technology that detects the inventory of products stored inside an unmanned sales device in real time, predicts the sales volume of products based on the date, time, temperature, humidity, etc., and automatically places orders based on the predicted sales volume and the inventory of products.

[0007] However, conventional technology faces a problem in that it is difficult to accurately predict sales volume for convenience foods, which are subject to fewer constraints regarding date, time, temperature, and humidity, making it difficult to guarantee a smooth supply of such foods. Furthermore, it fails to provide countermeasures for products with poor sales, making it difficult to minimize losses caused by underperforming convenience foods.

[0008]

[0009] The present invention aims to provide an unmanned convenience food sales system technology that ensures a smooth supply of convenience foods and minimizes losses caused by convenience foods with low sales, in order to solve the aforementioned problems.

[0010]

[0012] Herein, the management server comprises: a communication unit that communicates with the plurality of unmanned sales devices and storage terminals; a verification unit that verifies the sales volume of each convenient ready-to-eat food in a predetermined periodic unit from the time of each order for the convenient ready-to-eat food by the ordering party, based on the sales quantity of each convenient ready-to-eat food in the storage information received from the plurality of unmanned sales devices through the communication unit; a calculation unit that calculates the expected sales volume of each convenient ready-to-eat food for a subsequent period based on the sales volume trend of each convenient ready-to-eat food in a periodic unit confirmed by the verification unit; and a decision unit that predicts the time when the remaining quantity of each convenient ready-to-eat food is depleted based on the remaining quantity of each convenient ready-to-eat food confirmed from the storage information and storage information received from the plurality of unmanned sales devices and storage terminals through the communication unit relative to the expected sales volume of each convenient ready-to-eat food calculated by the calculation unit, and determines the ordering time of each convenient ready-to-eat food according to the prediction result.

[0013] In addition, the management server further comprises a storage unit that stores an advertisement video of at least one ready-to-eat food ordered by the ordering party and provides the stored advertisement video to the plurality of unmanned sales devices through the communication unit.

[0014] At this time, the plurality of unmanned sales devices are characterized by having a display means for storing and outputting an advertisement video provided from the management server.

[0015] In addition, the above-mentioned calculation unit is characterized by calculating the expected sales volume of a ready-to-eat food by adjusting the sales volume of the ready-to-eat food confirmed by the above-mentioned verification unit for a predetermined periodic unit, with respect to the ready-to-eat food related to the advertisement video stored in the above-mentioned storage unit.

[0016] Meanwhile, the above decision unit stores expiration date information for each ready-to-eat food ordered by the ordering party, and is characterized by deciding to stop ordering the ready-to-eat food only when the difference in days between the predicted ordering time of the specific ready-to-eat food and the expiration date of the ready-to-eat food is within a preset standard number of days.

[0017] In addition, the above management server is characterized by further including a control unit that controls each unmanned vending machine through the above communication unit and adjusts the sales price of each ready-to-eat food being sold at each unmanned vending machine.

[0018] In addition, the adjustment unit is characterized by controlling the plurality of unmanned sales devices to lower the sales price of the ready-to-eat food, limited to ready-to-eat food for which the difference in days between the ordering time predicted by the decision unit and the consumption period is within a preset standard number of days.

[0019]

[0020] The unmanned sales system for determining a suitable ordering time for each convenient ready-to-eat food according to the present invention predicts the suitable ordering time for each convenient ready-to-eat food based on the remaining quantity of each convenient ready-to-eat food stored in the unmanned sales device and the remaining quantity of each convenient ready-to-eat food stored in a storage unit that supplies multiple convenient ready-to-eat foods to each unmanned sales device, and determines the order based on the prediction result, thereby enabling the smooth supply of convenient ready-to-eat foods.

[0021] In addition, the unmanned ready-to-eat food sales system according to the present invention, which determines the appropriate ordering time for each ready-to-eat food, determines to stop ordering ready-to-eat foods with low sales based on the predicted ordering time for each ready-to-eat food, the expected depletion time for each ready-to-eat food, and the expiration date of each ready-to-eat food, and performs a downward adjustment of the sales price of the ready-to-eat food on the unmanned sales device, thereby preventing unnecessary orders and promoting the depletion of sales of the ready-to-eat food, and thus has the effect of minimizing losses caused by ready-to-eat foods with low sales.

[0029]

[0030] FIG. 1 schematically illustrates an unmanned ready-to-eat food sales system for determining a suitable ordering time for each ready-to-eat food according to a preferred embodiment of the present invention, and FIG. 2 illustrates the configuration of each management server in an unmanned ready-to-eat food sales system for determining a suitable ordering time for each ready-to-eat food according to a preferred embodiment of the present invention.

[0031] Referring to FIG. 1, the unmanned ready-to-cook food sales system for determining a suitable ordering time for each ready-to-cook food according to a preferred embodiment of the present invention may include: a management server (100) that is stored in a refrigerated or frozen form and determines an ordering time for each of the multiple ready-to-cook foods (R) and requests an order for each ready-to-cook food (R) from an ordering party (not shown) according to the determined ordering time; a plurality of unmanned sales devices (200) in the form of vending machines that sell ready-to-cook foods (R) that can be cooked using simple heating cooking tools, etc.; and a storage terminal (300) that is individually placed in at least one storage unit where the multiple ready-to-cook foods (R) are primarily stored, so as to distribute and supply the ready-to-cook foods (R) ordered by an ordering party (not shown) to the multiple unmanned sales devices (200) located adjacent to each other.

[0032] Hereinafter, the configuration of an unmanned sales device (200) that communicates with a management server (100) and sells a ready-to-cook food (R), and a storage terminal (300) that is placed in a storage facility that distributes and supplies the ready-to-cook food (R) to the unmanned sales device (200), will be described first, and the configuration of the management server (100), which is a characteristic configuration of the present invention, will be described later with reference to the attached drawings.

[0033] The unmanned sales device (200) is configured in the form of an automatic vending machine in which a plurality of convenient ready-to-eat foods (R) are stored in a refrigerated or frozen state, and the convenient ready-to-eat foods (R) requested by the buyer are dispensed and provided according to the buyer's purchase payment. It is connected to a communication network and can provide storage information regarding the types of convenient ready-to-eat foods (R) stored in the device, the sales quantity of each convenient ready-to-eat food (R), and the remaining storage quantity to the management server (100).

[0034] Meanwhile, each unmanned sales device (200) may be provided with a combined form of a display means (210) that outputs an advertisement video of various products including a ready-to-cook food (R) currently on sale, and the display means (210) includes a predetermined storage unit in which the advertisement video is stored, and the unmanned sales device (200) can store the video provided by the management server (100) through a communication network and output the stored advertisement video according to a pre-set schedule.

[0035] A storage terminal (300) is individually placed in at least one storage unit (not shown) in which a plurality of convenient ready-to-eat foods (R) ordered by an orderer (not shown) and supplied to each unmanned sales device (200) are stored in a refrigerated or frozen form, and storage information including the type of convenient ready-to-eat food (R) stored in the storage unit (not shown), the supply quantity of each convenient ready-to-eat food (R) supplied to each unmanned sales device (200), and the remaining storage quantity can be updated and entered.

[0036] Here, in order to receive a supply of ready-to-eat food (R) from each storage unit (not shown), a single storage unit (not shown) and at least one unmanned sales unit (200) may form a group (G1, G2, G3) as in FIG. 1, and at this time, the multiple unmanned sales units (200) may form a group in an n:1 matching form with a single storage unit (not shown) located at a distance below a certain distance.

[0037] Accordingly, the storage information updated and input at the storage terminal (300) placed in each storage (not shown) should also be understood to include the type and remaining quantity of the ready-to-eat food (R) stored in the storage (not shown), and the quantity of each ready-to-eat food (R) supplied to at least one unmanned sales device (200) within the group. At this time, the storage information updated and input at each storage terminal (300) may also include information about the target unmanned sales device (200) to which the ready-to-eat food (R) stored in the storage is to be supplied.

[0038] Referring to FIGS. 1 and 2, the management server (100) receives collection information and storage information from a plurality of unmanned sales devices (200) and storage terminals (300), calculates the sales volume of each convenient ready-to-eat food (R) in a predetermined periodic unit, calculates the expected sales volume of each convenient ready-to-eat food (R) for a subsequent periodic unit through the calculated sales volume of each convenient ready-to-eat food (R), and can individually calculate the ordering time of each convenient ready-to-eat food (R). It may include a communication unit (110), a storage unit (120), a verification unit (130), a calculation unit (140), a decision unit (150), and an adjustment unit (160).

[0039] The communication unit (110) may be provided in the form of a conventional wired / wireless communication module connected to a communication network to communicate with a plurality of unmanned sales devices (200) and storage terminals (300).

[0040] The storage unit (120) stores an advertisement video of at least one ready-to-eat food (R) ordered by an orderer (not shown), and can provide the stored advertisement video to multiple unmanned sales devices (200) through the communication unit (110). At this time, the storage unit (120) can simultaneously transmit an advertisement video uploaded by an administrator to all unmanned sales devices (200) connected to the communication network, and in some cases, can transmit an advertisement video designated by an administrator only to specific unmanned sales devices (200) in a limited manner.

[0041] The verification unit (130) can verify the sales volume of each convenient ready-to-eat food (R) in a predetermined periodic unit from the time of ordering each convenient ready-to-eat food (R) by the ordering party (not shown) through the sales volume of each convenient ready-to-eat food (R) in the collection information received from the multiple unmanned sales devices (200) via the communication unit (110). At this time, the verification unit (130) can additionally verify the sales volume of each convenient ready-to-eat food (R) by a single unmanned sales device (200) and the total sales volume by all unmanned sales devices (200) through the collection information received from the multiple unmanned sales devices (200), as well as the sales volume by group unit and the sales volume by unmanned sales devices (200) within the group through the storage information provided by the storage terminal (300).

[0042] The calculation unit (140) can calculate the expected sales volume of each convenient ready-to-eat food (R) for the subsequent period through the sales volume trend of each convenient ready-to-eat food (R) confirmed by the verification unit (130).

[0043] At this time, the calculation unit (140) may calculate the expected sales volume of the ready-to-eat food (R) by adjusting the sales volume of the ready-to-eat food (R) confirmed by the verification unit (130) for a predetermined periodic unit, with respect to the ready-to-eat food (R) related to the advertisement video stored in the storage unit (120).

[0044] In addition, the calculation unit (140) can also calculate the expected sales volume of each convenient ready-to-eat food (R) for a specific group of unmanned sales devices (200) or an individual unmanned sales device (200) through the group unit sales volume of each convenient ready-to-eat food (R) and the sales volume of each unmanned sales device (200) within the group confirmed by the verification unit (130).

[0045] The decision unit (150) can predict the time when the remaining quantity of each convenient ready-to-eat food (R) is exhausted based on the remaining quantity of each convenient ready-to-eat food (R) confirmed from the collection information and storage information received from multiple unmanned sales devices (200) and storage terminals (300) via the communication unit (110) compared to the expected sales volume of each convenient ready-to-eat food (R) calculated by the calculation unit (140), and determine the ordering time of each convenient ready-to-eat food (R) based on the prediction result.

[0046] Additionally, when the ordering time for a specific convenient ready-to-eat food (R) determined by the decision unit (150) arrives, the decision unit (150) may directly request an order for the convenient ready-to-eat food (R) from an ordering party (not shown). At this time, the decision unit (150) checks the remaining quantity of the convenient ready-to-eat food (R) from multiple unmanned sales devices (200) and storage terminals (300) a predetermined number of days prior to the ordering time of the convenient ready-to-eat food (R). Subsequently, if the confirmed remaining quantity of the convenient ready-to-eat food (R) is less than 30% of the total quantity at the previous ordering time, the remaining quantity is repeatedly checked at predetermined time intervals until the determined ordering time. If the remaining quantity is less than 15% of the total quantity at the previous ordering time, the decision unit may request an immediate order for the convenient ready-to-eat food (R) from an ordering party (not shown) regardless of the predetermined ordering time.

[0047] In addition, the decision unit (150) may store expiration date information for each ready-to-eat food (R) ordered by an orderer (not shown). Since the expiration date of ready-to-eat food (R), such as a meal kit, is not long, there is a problem that the expiration date may arrive before waiting for the determined ordering time. Therefore, the ordering of the ready-to-eat food (R) may be delayed only if the difference in days between the predicted ordering time for a specific ready-to-eat food (R) and the expiration date of the ready-to-eat food (R) is within a predetermined standard number of days. In the case of a ready-to-eat food (R) for which ordering has been repeatedly delayed, it may be decided to stop ordering in the future.

[0048] Meanwhile, the sales volume of each ready-to-eat food (R) may vary depending on the type of ready-to-eat food (R) preferred in each region, and for this reason, the decision unit (150) may request orders with different distribution ratios for each storage unit (not shown) of multiple ready-to-eat foods (R) ordered from the ordering party (not shown), based on the estimated sales volume of each ready-to-eat food (R) in the unmanned sales device (200) group unit calculated from the calculation unit (140).

[0049] In addition, since the preferred type of ready-to-eat food (R) may also differ depending on the installation location of a specific unmanned sales device (200), the decision unit (150) may generate and provide supply plan information for each ready-to-eat food (R) so that the type and amount of ready-to-eat food (R) supplied to each unmanned sales device (200) within the group differ according to the expected sales volume of each ready-to-eat food (R) of each unmanned sales device (200) calculated by the calculation unit (140).

[0050] The control unit (160) can individually control each unmanned sales device (200) through the communication unit (110) to adjust the sales price of each ready-to-eat food (R) being sold at each unmanned sales device (200).

[0051] Here, the adjustment unit (160) may control multiple unmanned sales devices (200) to lower the sales price of the ready-to-eat food (R) and promote the depletion of sales of the ready-to-eat food (R) by controlling the ready-to-eat food (R) for which the difference in days between the predicted order time predicted by the decision unit (150) and the expiration date is within a preset standard number of days, such as ready-to-eat food (R) with a short remaining expiration date and ready-to-eat food (R) with low sales volume that will be replaced by other ready-to-eat food (R).

[0052]

[0053] In other words, the unmanned ready-to-eat food sales system according to the present invention, which determines the appropriate ordering time for each ready-to-eat food, predicts the appropriate ordering time for each ready-to-eat food based on the remaining quantity of each ready-to-eat food stored in the unmanned sales device and the remaining quantity of each ready-to-eat food stored in a storage unit that supplies multiple ready-to-eat foods to each unmanned sales device, and determines the order based on the prediction result, thereby enabling the smooth supply of ready-to-eat foods.

[0054] In addition, the unmanned ready-to-eat food sales system according to the present invention, which determines the appropriate ordering time for each ready-to-eat food, determines to stop ordering ready-to-eat foods with low sales based on the predicted ordering time for each ready-to-eat food, the expected depletion time for each ready-to-eat food, and the expiration date of each ready-to-eat food, and performs a downward adjustment of the sales price of the ready-to-eat food on the unmanned sales device, thereby preventing unnecessary orders and promoting the depletion of sales of the ready-to-eat food, and thus has the effect of minimizing losses caused by ready-to-eat foods with low sales.

[0055]

[0056] The embodiments of the present invention described above are disclosed for illustrative purposes only, and those skilled in the art with ordinary knowledge of the present invention may make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the following claims.
