The present disclosure relates to producing embroidery designs, and more particularly, to an embroidery design production management apparatus and method that enable a producer to predict a delivery schedule for an order quantity for checking whether it is possible to obtain the production order of an order placer and produce and manage the ordered embroidery designs according to the order schedule of the order placer, in producing embroidery designs.
With an increased need for mass production and mass consumption, manufacturing companies are likely to produce products on a sublet production basis rather than on a self-production basis. In manufacturing products on a self-production basis, a single manufacturing company performs all tasks including developing, designing, manufacturing, process-managing, maintaining, and repairing of products. According to the sublet based manufacturing, an order placer, which is a company that desires to sell products at a market, places its order for manufacturing of specific products, and a product producer, which is a company that obtains relevant production equipment for manufacturing, subsequently manufactures the specific products according to the placed order.
In the sublet based manufacturing, however, a competition between producers for obtaining a production order is intense, and thus, it is important to quickly and accurately determine whether it is possible to accept the production order. That is, it is important to predict a delivery schedule for supplying the quantity of products, ordered by an order placer, based on the productive capacity of a producer, and establish an efficient production plan based on the predicted delivery schedule.
To date, however, in embroidery design production for embroidering various patterns, pictures, and letters on cloth by using an embroider machine, whether it is possible to obtain a production order is determined depending on only the experience of a producer. That is, embroidery design producers predict a delivery schedule for an order quantity based on the past experience without analyzing in detail a self-productive capacity, and determine whether it is possible to obtain a production order. Such method is efficiently applied when a process of producing embroidery designs is simple, but, when the process of producing embroidery designs is complicated, the method is inadequate to predict a delivery schedule. For this reason, a producer may obtain a production order in a state in which the producer cannot accurately predict a delivery schedule, namely, the production order is out of the productive capacity of the producer, in which case the producer inefficiently manages an embroidery machine and users for confidently processing the request of an order placer, causing the increase in the manufacturing cost.
There are no apparatus and method for accurately predicting a delivery schedule for an order quantity in association with the embroidery design production. However, in fields (for example, a semiconductor field) other than the embroidery design production, various technologies for predicting and fulfilling a delivery schedule have been proposed. As an example of a conventional method and apparatus for predicting and fulfilling a delivery schedule, Korean Patent Publication No. 10-2009-0097623 discloses a system of a proactive scheduling approach using simulation. However, the system of the proactive scheduling approach using simulation disclosed in the patent document cannot be applied to the embroidery design production. That is, the conventional technology has no configuration for analyzing and performing an embroidery design, and thus, it is difficult to actively search a plurality of embroidery machines of a producer and identify embroidery machines, which are available and capable of processing the embroidery design (hereinafter referred to as an available embroidery machine). Also, it is difficult to analyze productivities by a process for a factory line that is configured by analyzing productivities by a machine for available embroidery machines and combining the available embroidery machines. Thus, it is unable to obtain the optimal process sequence for the embroidery design production. For this reason, an embroidery design producer may not be able to accurately predict a delivery schedule for an order quantity. Also, the conventional technology cannot provide an effective and quick solution to an error in an embroidery machine which occurs in producing embroidery designs, and thus, a producer may run into a problem in producing defective embroidery designs.
The present disclosure provides some embodiments of an embroidery design production management apparatus and method that enable a producer to predict a delivery schedule for an order quantity for checking whether it is possible to obtain the production order of an order placer and produce and manage the ordered embroidery designs according to the order schedule of the order placer, in producing embroidery designs.

Also, the networks 1 and 2 may be operated based on known network protocols such as TCP/IP, FTP, and HTTP, but are not limited thereto.
Referring again to
The central processing module 110 may interworking-control the other modules 120 to 190 of the embroidery design production management apparatus 100 such that the embroidery design production is smoothly performed according to a series of process sequences. The central processing module 110 may be a general computer, a computer for a special purpose, a distributed processing system, or one independent operation processing apparatus, but is not limited thereto.
The interface module is connected to the terminal equipment of the order placer 30 over the network 1, and also connected to at least one or more embroidery machines 20 of a corresponding producer 10 over the network 2. Therefore, the order placer 30 may check machine information of the embroidery machine 20 which is owned and operated by each of the producers 10 to 15. Similarly, one producer 10 may be connected to the other producers 11 to 15 over the network 1, so that the producer 10 can check machine information of the embroidery machines 21 to 25 which are owned and operated by the other producers 11 to 15 respectively. The machine information may include information such as the type of an embroidery machine, an embroidery type, an operation state, a suspension state, and a standby state. As described above, the producers 10 to 15 may share the use of the embroidery machines 20 to 25, and thus, depending on the case, the one producer 10 may use the embroidery machines 21 to 25 of the respective other producers 11 to 15.
The input/output module 130 may authenticate the order placer 30 connected thereto via the interface module 120, and the producer 10 managing the embroidery design production management apparatus 100. Also, the input/output module 130 may authenticate a user who places embroidery design products with the embroidery machine 120. The authentication procedure may be performed using inputting identifier (ID) and a password, but is not limited thereto.
The embroidery design production management apparatus 100 may receive production order information regarding the embroidery design production from the order placer 30 via the input/output module 130, and receive a producer setting value from the producer 10. Also, the embroidery design production management apparatus 100 may receive the inquiry of the order placer 30, and output a response from the producer 10 regarding the inquiry. The order information received from the order placer 30, as illustrated in
The producer setting value may include the number of times the breaking of a thread occurs, a loss time when the breaking of a thread occurs, a loss time in replacing one head, any other loss time, daily working hours, a work range of one head, a design price, a design margin, necessary working days, and the number of available embroidery machines. The producer setting value indicates a value that is directly measured or checked by a user.
The input/output module 130 may include a keyboard, a mouse, a pointing device, a microphone, a joystick, and a scanner as an input means, and include a monitor display, a speaker, and a printer as an output means. However, the present disclosure is not limited thereto. Also, the input/output module 130 may be included in various portable electronic terminals connectable to the interface module 120 over the network 1. In this case, the producer 10 having the portable electronic terminal may input or output various information regarding the embroidery design production to check the various information irrespective of the time and the place.
The data storage module 140 may store an access record for the networks 1 and 2, via the interface module 120. Various information input and output via the input/output module 130 may be automatically stored in the data storage module 140, or may be stored according to a selection by the order placer 30 or the producer 10. The various information stored in the data storage module 140 may be repeatedly output via the input/output module 130. The order placer 30 or the producer 10 may change or delete the content of information within a given authorization range, in which case the changed information may be again stored in the data storage module 140.
The design analysis module 150 analyzes the embroidery designs S1 to S4 in the order information input via the input/output module 130 to obtain design information and stitch information. As illustrated in
The productivity prediction module 160 may search the plurality of embroidery machines 20 to 25 connected to the networks 1 and 2 to identify available embroidery machines, based on the design information 2202 and stitch information 2204 (which are obtained by the design analysis module 150) and the producer setting value input by the producer 10, and calculate machine productivity (for example, necessary working days per machine) for the identified available embroidery machines. Also, the productivity prediction module 160 may calculate process productivity, for example, production quantities per process and the number of necessary users per process, in a factory line that is configured by combining the available embroidery machines. A method of calculating machine productivity and process productivity will be described in an embroidery design production management method to be described below.
The productivity prediction module 160, as illustrated in
The productivity prediction module 160, as illustrated in
The productivity prediction module 160, as illustrated in
In the present embodiment, to calculate machine productivity and process productivity, the productivity prediction module 160 may calculate a loss time, predicted working hours and number of production pieces, the number of workable design pieces per one head, production quantities per process, necessary working days per machine, and the number of necessary users per process. A method of calculating a loss time, predicted working hours and number of production pieces, the number of workable design pieces per one head, production quantities per process, necessary working days per machine, and the number of necessary users per process will be described in the embroidery design production management method to be described below.
Since the result predicted by the productivity prediction module 160 satisfies the production order condition of the order placer 30, when the producer 10 takes a placed order, the process processing module 170 starts to produce embroidery designs according to the optimal process sequence that is used for predicting a delivery schedule. To this end, when it is required to expand a productive capacity by using the respective embroidery machines 21 to 25 of the other producers 11 to 15, the process processing module 170 may show the order content to the other producers 11 to 15, and transmit respective messages, requesting the use of the embroidery machines 21 to 25, to the other producers 11 to 15. When the one producer 10 includes all embroidery machines necessary for producing embroidery designs, the process processing module 170 may not transmit a message, requesting the provision of the production order content and the use of an embroidery machine, to the other producers 11 to 15. When the process processing module 170 receives acknowledgement messages from the respective producers 11 to 15 receiving a request for the use of the embroidery machines 21 to 25, the process processing module 170 may transmit an allocated work instruction to a corresponding embroidery machine.
When at least one of the other producers 11 to 15 does not acknowledge the request for the use of the embroidery machines 21 to 25 due to a special reason, the process processing module 170 may repeatedly search and identify embroidery machines other than the embroidery machines of the producer 10 which has not acknowledged the request, such that the embroidery design production is performed according to the optimal process sequence. Also, when an embroidery machine, which is necessarily used for the embroidery design production among the embroidery machines 20 to 25 connected to the process processing module 170 over the networks 1 and 2, is not included in a search target, the process processing module 170 may add a virtual embroidery machine (for example, an embroidery machine which is being sold) into the search target according to the setting of the producer 10, and may repeatedly search and identify available embroidery machines.
The production management module 180 receives an allocated work instruction from the process processing module 170, and performs the production management of a working embroidery machine. The production management module 180, as illustrated in
Moreover, as illustrated in
The error management module 190 may receive machine state information from a working embroidery machine. The machine state information may include an abnormal state message indicating that an embroidery machine is in an abnormal state. The error management module 190 may output the current management status of embroidery machines via the input/output module 130. The output screen may include a line field displaying a factory line with embroidery machines arranged therein, a model field displaying the type of a corresponding embroidery machine, an error code field, an occurrence time field displaying a time at which an abnormal state message is generated, and a description field describing an abnormal state. Also, the output screen may include a self-repair field providing information necessary for repairing the abnormal state. When a user clicks on a self-repair field icon for a desired embroidery machine, the self-repair field may provide information, which is necessary for repairing the abnormal state, in the form of at least one of text data and multimedia data. Also, the output screen may include a current progress status field displaying an after-sales service status for an embroidery machine having an abnormal state. In the present embodiment, the current progress status field may provide whether to request an after-sales service and an after-sales service progress status according to a user clicking on an icon that indicates the current progress status of a corresponding embroidery machine, and may include an after-sales service (A/S) completion field displaying the completion of an after-sales service.

As illustrated in
As described above, the error management module 190 may provide information for repairing a corresponding abnormal state based on the content of the abnormal state, in the form of at least one of the text data 4200 and the multimedia data 4300. A user may adjust an embroidery machine and perform any necessary management based on information provided by the text data 4200 and the multimedia data 4300, for repairing the abnormal state. When the abnormal state is continued to exist even after the adjustment or the management, the error management module 190 may provide the A/S request message 4400 to the producer 10. After the A/S request, the error management module 190 may monitor a time taken until an A/S processing agent arrives, an A/S progress status, and whether an after-sales service is completed.
Hereinafter, an embroidery design production management method according to an embodiment of the present disclosure using the above-described embroidery design production management apparatus will be described with reference to the accompanying drawings.

To determine available embroidery machines, embroidery machines that are included a producer may be first searched, and embroidery machines that other producers connected to a network may be searched thereafter. Also, when embroidery machines necessary for embroidery design production are not searched, the embroidery design production management method according to an embodiment of the present disclosure may third add a virtual embroidery machine (purchasable or rentable embroidery machine), which is set by the producer, into a search target, and perform a research.

Further, Operation S400 may calculate a loss time, predicted working hours and number of production pieces, the number of workable design pieces per one head, production quantities per process, necessary working days per machine, and the number of necessary users per process.
A loss time may be calculated with the following Equation (1).
(total loss time[min]in producing one piece)=(loss time[min]in breaking of thread)+(loss time[min]in replacing bobbin)+(other loss time[min]) (1)
where the loss time when breaking of thread occurs and the loss time in replacing bobbin may be calculated with the following Equations (1-1) to (1-5).
(loss time[min]in breaking of thread)=(number of breakings of thread×loss time[sec]when breaking of thread occurs)/60 (1-1)
(loss time[min]in replacing bobbin)=(number of replacements of bobbin×total number of heads×loss time[sec]in replacing one head)/60 (1-2)
when general shuttle,(number of replacements of bobbin)=(quantity[meter]of consumed bottom thread)/100 (1-3)
when large shuttle,(number of replacements of bobbin)=(quantity[meter]of consumed bottom thread)/150 (1-4)

where the number of breakings of thread, the loss time when breaking of thread occurs, the loss time in replacing one head, the number of heads based on number of available embroidery machines, and the other loss time including a piece replacement time are input as a plurality of producer setting values, and the entire needle length of upper thread and the number of replacements of bobbin are calculated in an embroidery design analysis operation.
Predicted working hours and the number of production pieces may be calculated with the following Equations (2) and (3).
(predicted time[min]in producing one design)=Sum(RPM_TABLE[M][S]+RPM_TABLE[M][S]+RPM_TABLE[M][S]+) (2)
where [M] denotes the type of an embroidery machine, [S] denotes a stitch length, and RPM_TABLE[M][S] denotes a defined time for the needle length of a selected embroidery machine.
(number[times]of production pieces per daily working hours)=(daily working hours[hour]×60 [min])/(predicted time[min]in producing one design+total loss time[min]in producing one piece) (3)
where daily working hours are input as a producer setting value, predicted time in producing one design is calculated with Equation (2), and total loss time in producing one piece is calculated with Equation (1).
The number of workable design pieces per one head may be calculated with the following Equation (4).
(number of workable design pieces per one head)=Rxcnt×Cycnt (4)
where, as illustrated in
Production quantities per process and necessary working days per machine may be calculated with the following Equations (5) and (6).
(production quantities per process)=(number[times]of production pieces per daily working hours)×(number[times]of workable design pieces per one head)×(number of heads)×(necessary working days by embroidery machine) (5)
(necessary working days per machine)=(production quantities per process/N)/(number[times]of production pieces per daily working hours×number of workable design pieces per one head×number of heads) (6)
where the number of production pieces per daily working hours is calculated with Equation (3), the number of workable design pieces per one head is calculated with Equation (4), the number of heads is input as a producer setting value, and N denotes the number of selected embroidery machines.
The number of necessary users per process may be calculated with the following Equation (7).
(number of necessary users per process)=(sum of heads per process machine/number of basic heads per user×daily working hours[hour]/(basic working hours per user) (7)
where the sum of heads per process machine is automatically calculated in selecting an embroidery machine, and the number of basic heads per user, the daily working hours, and the basic working hours per user are input as a plurality of producer setting values.
Operation S400, which calculates machine productivity and process productivity, may predict working days for the critical path, having the longest working days in a plurality of factory lines, as a delivery schedule for the order quantity. Also, operation S400 may calculate the estimated profit and loss and the estimate cost per unit for the embroidery design production by calculating productivity.
The predicted delivery schedule is a prediction result value that allows for the production of ordered embroidery designs based on the productive capacity of a producer. Operation S500, which compares the delivery schedule and the order schedule, is performed in order for the producer to determine whether it is possible to obtain a placed order. The comparison of the delivery schedule and the order schedule may be repeatedly performed until the delivery schedule satisfies the order schedule.
When it is determined through the comparison of the delivery schedule and the order schedule that it is possible to obtain the placed order, the embroidery design production may be started. Operation S700, which starts the embroidery design production, performs the production according to the optimal process sequence that has been set for predicting the delivery schedule. When an embroidery machine included in a factory line for predicting the delivery schedule is an embroidery machine that is included in the other producer, operation S700 may include operation S710 that requests the use of the embroidery machine from the other producer, operation S720 that transmits an allocated work instruction to the embroidery machine after the requested use of the embroidery machine is approved.
After the embroidery design production is performed, the production management operation S800 for enhancing productivity is performed. Such production management operation S800 may include operation S810 that monitors a current work status in the embroidery design production in real time, operation S820 that manages a work schedule for an embroidery machine or a user, and operation S830 that compares and analyzes productivities based on the predicted delivery schedule and an actual work schedule.
Operation S812, which checks whether an error occurs in the embroidery machine in performing the embroidery design production, may be performed after operation S810 that monitors the current work status in embroidery design production, or may be performed simultaneously with monitoring operation S810. Also, the embroidery design production management method according to an embodiment of the present disclosure may include operation S900 that performs error management so as to resolve the error which occurs in the embroidery machine in performing the embroidery design production. As illustrated in
While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the disclosures. Indeed, the novel methods and apparatuses described herein may be embodied in a variety of other forms; furthermore, various changes, modifications, correactions, and substitutions with regard to the embodiments described herein may be made without departing from the spirit of the disclosures. Also, the elements and operations of the sewing design manufacturing management apparatus and method of the present disclosure may be implemented as a plurality of distributed hardware modules or software modules.
Therefore, the accompanying claims and their equivalents including the foregoing modifications are intended to cover the scope and spirit of the disclosures, and are not limited by the present disclosures.
As described above, according to the embroidery design production management apparatus and method in accordance with the embodiments of the present disclosure, a delivery quantity and a delivery schedule for determining whether it is possible to obtain a placed order can be accurately predicted by a parametric estimating scheme instead of an analogous estimating scheme.
According to the embroidery design production management apparatus and method of the present disclosure, an order taker can easily take an order, associated with embroidery design production, from an order placer over a network. Also, the embroidery design production management apparatus and method of the present disclosure searches information of embroidery machines connected to the network based on placed order information to identify available embroidery machines, and calculates process productivity in a factory line which is configured by analyzing machine productivity for the identified available embroidery machines and combining the available embroidery machines, thereby obtaining the optimal process sequence. That is, the embroidery design production management apparatus and method of the present disclosure can predict a delivery schedule for the order quantity so as to enable a producer to check whether it is possible to obtain the production order of an order placer. Also, the embroidery design production management apparatus and method of the present disclosure provides an effective and quick solution to the error of an embroidery machine which occurs in producing embroidery design products according to the obtained optimal process sequence, thus enabling the producer to perform production management according to the order schedule of the order placer. Therefore, the producer can quickly and accurately determine whether it is possible to obtain the production order of the order placer, and thereby preventing a production problem which is caused in producing embroidery designs. The producer can obtain the production order of the order placer based on a productive capacity, and thus, smoothly manage an embroidery machine and users, thereby decreasing production burden and enhancing productivity in an embroidery design production process.
