How does the sewing water flow for a single piece?

1. What is single-piece flow?

Single-piece flow is also called unit synchronous flow. Single-piece flow is the comprehensive and effective utilization of personnel, equipment, and logistics, which is organized and organized. Planned, targeted schedules balance production for each unit! In production activities, the production batch is based on one batch, and there is no stagnation between the previous and subsequent processes. Every time a process is completed, a process is self-inspected and a production method is called a flow production method, referred to as single-piece flow.

2. Characteristics of single-piece flow:

1. Target management: Production capacity is targeted, and industrial engineers set target production capacity for each unit (process) of the product;

2. Time management: Time is quantified, and industrial engineers set the target operating time for each unit (process) of the product;

3. Finished products are produced quickly, Quick response to quality issues, zero batch quality accidents;

4. Push-forward and pull-back: It is different from the traditional production method. In the traditional production method, the production line is passive and can only wait for materials and cutting from the front department. , embroidery, and printing determine the normal operation of production, while single-piece flow production is proactive. The pre-processes must meet the production line, and everything is planned for production. Forward push is not just forward push on the production line, it includes orders, material supply, and product reprocessing. Pulling back is to meet customer needs and pull the entire production and supply chain.

3. Why should we implement single-piece flow?

1. Shorten the production cycle. Since the single-piece flow is a synchronous operation of all production personnel in different processes, the waste of human resources is reduced to the greatest extent, and the improvement of production efficiency greatly shortens the production cycle.

2. Reduce work-in-progress inventory: Since the single-piece flow production form is a back-pull production model, the previous process only produces as much as the last process requires, so its manufacturing process is Once the synchronous operation is completed, one finished product will leave the workshop. Unless there are special circumstances, almost no inventory can be achieved.

3. Save production space: Since the single-piece flow is a process that quickly produces finished products, there is no need to stock any materials during the production process, which greatly saves production space.

4. Reduce the number of defective products: The production model of the single-piece flow is based on one piece as a batch. The entire assembly line operates synchronously to produce one finished product at a time, so problems can be discovered in time and minimized. The probability of defective products occurring.

5. Improve productivity: The essence of single-piece flow is unit synchronization, and each position is a unit. Habitual synchronization and coordination cultivate the spirit of teamwork, high unity, and high concentration, which greatly improves productivity.

4. Pre-production preparation:

1. In the traditional production method, the warehouse is only used for temporary turnover of goods, or for stacking inventory, while in the single-piece flow production method, the warehouse has been It is no longer the above two functions. Single-piece flow particularly emphasizes that pre-production preparations must be fully prepared and completed. Therefore, the function of the warehouse is changed. In Taiwan-funded or Japanese-funded enterprises, the warehouse is not called a warehouse but called material preparation. This class is also called the material preparation department. The so-called material preparation refers to the full preparation of materials (for example: washed labels, towels, and ribbons are all shrunk and cut by the material preparation department in advance according to the order making requirements. This can avoid temporary replenishment due to insufficient quantities during production. materials, or the time is too late, resulting in the suspension of production or reduction of finished products and customer claims),

2. The business department’s material supply information and material arrival status must be disclosed and timely,

For production The coordination requirements are higher and closer;

3. The requirements for equipment and auxiliary tools are higher, and industrial engineering personnel must be cooperated to carry out effective equipment transformation;

4. The skills of employees Timely and effective training must be carried out according to different types of work;

5. The process requirements and standards of production offices are higher. Traditional production offices generally do not consider the convenience and practical operability of large quantities of goods, while industrial The concept of engineering requires that the transformation of process structure must start from the production office. Effective improvement of process structure will help improve production efficiency!

Note: Necessary conditions for single-piece flow:

1. All materials for the entire item must be complete.

2. The styles cannot be embroidered as semi-finished products.

3. Use automatic thread trimming and high-quality backstitching equipment.
