Labor productivity is the productivity of workers, which is manifested in the labor time consumed by producing unit goods. This working time is the product of the number of workers and working time. If we want to improve labor productivity, we must reduce working hours. At present, the production equipment of famous clothing enterprises in China such as Youngor and Shanshan has reached the most advanced level in the world. These equipments have played an important role in the production of high-quality garments in China, and improved the competitiveness of China garments in the world market. However, there is a big gap between our garment enterprises and Japanese garment enterprises in terms of equipment internal transformation and how to improve production efficiency. Here are four ways to improve our production efficiency.
Improve garment production equipment and reduce production processes.
At present, there are many redundant processes in domestic garment manufacturing enterprises. For example, many garment production processes have to go through the process of preliminary cutting, sewing (bonding and ironing) and fine cutting. As long as we use sawing knives, hydraulic presses or automatic cutting machines (CAM) in enterprises with poor economic conditions, we can completely turn the initial cutting into fine cutting, and save a cutting process. For another example, in the sewing process, by using automatic equipment, such as German Dukepu 805 automatic bagging machine, the original two processes (cloth folding and ironing-patch pocket sewing) are changed to patch pocket sewing, and the production output of one person is equivalent to that of four people in the original process.
Selecting special automation equipment to improve labor productivity
With the progress of science and technology, the automation degree of many special sewing equipment is getting higher and higher, especially the use of servo motor, which saves a large number of mechanized transmission mechanisms in the equipment, makes the transmission and positioning of the equipment more accurate, greatly reduces the mechanical adjustment and wear of the equipment, and also reduces the labor proficiency of operators, resulting in that one person can operate multiple devices, greatly improving labor efficiency. At present, automatic bag opener, automatic sewing machine, automatic cloth puller, trousers saving machine, automatic vertical sewing machine and automatic bed cutter (CAM) are widely used in garment production. Compared with the previous manual operation, these devices have improved the efficiency by more than three times. The working feature of automatic equipment is that after the operator arranges the sewing pieces, according to the operation switch or automatic induction switch, the equipment automatically transports, sews and cuts the cloth pieces by the inherent fixture, and then automatically stacks them after sewing. Automatic equipment is generally equipped with a display, which can change the data to adjust the sewing shape and size, with high speed and counting and fault detection functions.
Add auxiliary equipment to reduce the auxiliary time outside sewing for operators.
There are many processes in garment production, and operators will spend more time on feeding preparation before sewing and stacking materials after sewing. We can consider refitting these equipment, adding auxiliary feeding and stacking devices, reducing the sewing time of operators and improving the output. For example, Hong Kong Yicheng Company's take-up rack after sewing shirt placket, and auxiliary feeding rack for shirt bloating, etc. The application of these auxiliary equipment will improve the production efficiency by more than 20%.
Relying on computer management to improve labor productivity
Automatic suspension system, also known as flexible production system, is a suspension transmission system that saves production management functions under computer control. It combines a plurality of garment production stations through a circulating transportation track, which has the function of reducing the sewing auxiliary time of operators, that is, reducing the wrapping time, putting clothes pieces and putting clothes pieces. In addition, it also has the function of computer production management. Before the system is started, as long as the production manager is arranged to type in the product production process and work station on the main control computer for operation, the computer will control the work station to transport clothes in turn according to the input requirements. If the same process requires multiple stations to process, the conveying station can be automatically adjusted according to the completion of multiple stations to ensure the process balance and smooth assembly line of the system. When the system works, when there is too much backlog in a certain station, it will be adjusted automatically, so that the production management personnel can adjust the technological process reasonably and balance the production. In actual production, the production efficiency can be improved by more than 20%.
Improving international competitiveness and clothing production efficiency is an urgent task for China clothing enterprises.
