Description

기계설비의 셋업시간 최소화 방법{METHOD FOR MINIMIZING SETUP TIME IN A MACHINE INSTALLATION}How to minimize set-up time of mechanical equipment {METHOD FOR MINIMIZING SETUP TIME IN A MACHINE INSTALLATION}

본 발명은 복수의 설비를 그룹관리토록 그룹으로 지정하는 단계, 그룹별 잔여수주량과 재고에 따른 생산계획량을 수립하는 단계, 각 설비별 세팅일정 및 작업시간을 산출하는 단계를 포함하며, 상기 각 설비별 세팅이 알고리즘에 의해 수행토록 설치되는 기계설비의 셋업시간 최소화 방법에 관한 것이다.The present invention includes the steps of designating a plurality of facilities as a group for group management, establishing a production plan according to the remaining order quantity and inventory for each group, and calculating a setting schedule and working time for each facility, wherein each facility It relates to a method of minimizing the setup time of a mechanical equipment installed so that star setting is performed by an algorithm.

일반적으로, 생산-주문형 동작을 갖는 제조 설비에 있어서, 다양한 머신 및 다양한 프로세스의 제어가 조절되어야 한다. In general, in a manufacturing facility with production-on-demand operation, the control of various machines and various processes must be coordinated.

소비자의 기대를 만족시키도록 짧은 사이클 시간 및 정확한 운송 스케줄을 제공하기 위해서는 항상 중요한 목적 및 문제점이 있다. There is always an important objective and problem in providing short cycle times and accurate transport schedules to satisfy consumer expectations.

이 때, 발생하는 문제점으로는, 복잡한 프로세스 믹스 및 생산물 믹스(mix)에서 선택하는 것과, 예상하지 못한 머신 정지 시간 및 장치의 배치에 관한 것이 있다. Problems that arise here include choosing from complex process mixes and product mixes, and unexpected machine downtime and arrangement of equipment.

효과적으로 로트를 스케줄하고 디스패치하는 것이 제조시 매우 중요한 문제로 대두되었다. Effectively scheduling and dispatching lots has become a very important issue in manufacturing.

각각의 제조 장비 내에서, 전형적으로 스케줄러는 프로세스될 이용 가능한 로트의 버퍼를 구동한다. Within each manufacturing equipment, typically a scheduler runs a buffer of available lots to be processed.

이용 가능한 로트의 버퍼는 전형적으로 이용 가능한 로트를 특정한 머신 또는 프로세스로 할당하는 디스패처로 공급된다.A buffer of available lots is typically fed to a dispatcher that allocates available lots to specific machines or processes.

그리고, 디스패치 시스템은 개루프 또는 폐루프일 수 있으며, 상기 개루프 디스패치 시스템은 시스템의 실제 성능 및 디스패치 결정을 고려하지 않고 디스패치 결정을 내린다. In addition, the dispatch system may be an open loop or a closed loop, and the open loop dispatch system makes a dispatch decision without considering the actual performance of the system and the dispatch decision.

또한, 개루프 디스패치 시스템은 프로세스의 개루프 모델에만 의존하고, 프로세스가 기대한 것만 수행한다고 가정한다. Also, open-loop dispatch systems rely only on the open-loop model of the process and assume that the process does only what it expects.

더하여, 폐루프 디스패치 시스템은 디스패치 결정을 내린 후 적절한 정보를 피드백하여 미래의 디스패치 결정의 향상을 돕는다. In addition, the closed-loop dispatch system feeds back appropriate information after making a dispatch decision to help improve future dispatch decisions.

이러한 폐루프 디스패치 시스템은 피드백에 의해 시스템에서 어떤 일이 발생하고 이러한 정보에 기초하여 디스패치 동작을 변화시키는지를 알게 된다.This closed-loop dispatch system knows by feedback what is happening in the system and changes the dispatch behavior based on this information.

이와같은 기술과 관련되어 종래의 특허 제689125호에 로트를 디스패칭하기 위한 시스템의 기술이 제시되고 있으며 그 구성은 도1에서와 같이, 워크 셀(10)은 스케줄러(12), 버퍼(14), 디스패처(16), 및 복수의 머신(18)를 포함하며, 각각의 머신(18)은 연관된 제어기(20)를 가질 수 있다. In relation to this technology, the prior art Patent No. 689125 discloses a system for dispatching a lot, and the configuration is as shown in FIG. 1 , the work cell 10 includes a scheduler 12 and a buffer 14 , a dispatcher 16 , and a plurality of machines 18 , each machine 18 having an associated controller 20 .

그리고, 상기 제어기(20) 기능은 디스패처(16)에 의해 수행되며, 각각의 머신(18)에 대하여 제어기(20)를 사용함으로써 프로세스가 제어기(20) 및 디스패처(16) 사이에 분포될 수 있다.And, the controller 20 function is performed by the dispatcher 16, and by using the controller 20 for each machine 18, the process can be distributed between the controller 20 and the dispatcher 16. .

또한, 상기 스케줄러(12)는 워크 셀(10)에 의해 프로세스될 로트(13)의 리스트를 개발하여, 로트(13)의 리스트를 버퍼(14)에 배치하고, 상기 로트(13)의 리스트는 하나 이상의 로트(22)를 포함하며, 상기 디스패처(16)는 버퍼(14) 내에서 이용 가능한 로트(22)를 취하여 각각의 로트(22)를 디스패치함으로써 워크 셀(10)의 동작을 최적화한다. Further, the scheduler 12 develops a list of lots 13 to be processed by the work cell 10, and places the list of lots 13 in a buffer 14, wherein the list of lots 13 is one or more lots 22 , wherein the dispatcher 16 optimizes the operation of the work cell 10 by taking the lots 22 available in the buffer 14 and dispatching each lot 22 .

더하여, 상기 디스패처(16)는 각각의 머신(18)로부터의 피드백 데이터(24)에 근거한 디스패치 결정을 기초로 하고, 상기 피드백 데이터(24)는 각각의 머신(18)로부터의 머신 메트릭스(26) 및 다운스트림 메트릭스 데이터(28)를 포함한다.In addition, the dispatcher 16 bases dispatch decisions based on feedback data 24 from each machine 18 , the feedback data 24 including machine metrics 26 from each machine 18 . and downstream metrics data 28 .

그러나, 상기와 같은 로트를 디스패칭하기 위한 시스템의 기술은, 단시간의 정확한 운송 스케줄을 제공하는데 있는 것으로 재고량이나 예상 수주량등에 의해 기계의 가동시간을 극대화 시킬 수 있는 등의 효과는 구현할 수 없는 것입니다.However, the technology of the system for dispatching a lot as described above is to provide an accurate transportation schedule in a short time, and it is impossible to realize the effect of maximizing the operation time of the machine by the amount of inventory or expected order quantity. .

After collecting information on sales or production management by using the enterprise resource planning (ERP) system, the production execution system (MES) completes the production plan establishment according to the remaining orders for each group, and the production process automation scheduling (APS) Calculates the setting schedule and working time for each facility by
In the setting for each facility, a person with high machine skill who is familiar with the setup manual for each facility can adjust the machine,
The remaining personnel are distributed by matching the tasks of material input, production product movement, scrap discharge, product storage box input, and machine check.
After calculating the setting schedule of each facility assembled in the SKD method, the setting schedule is arranged, and the dispatching rule is applied to provide the priority of setting for each facility,
The setting schedule is a method of minimizing the setup time of a machine so that it is performed by an algorithm that manages the operating time of the facility by adjusting the setup time and selecting additional production according to the total inventory amount and expected order quantity. 삭제delete 삭제delete 삭제delete
