The production line is the route through which the product's production process passes, that is, starting from the time when the raw material enters the production site, and the route constituted by a series of production activities such as processing, transportation, assembly, and inspection. The production line is organized according to the principle of objects and a form of production organization that completes the product process, that is, according to the principle of product specialization, equipped with various equipment and workers required for the production of a certain product (zero, parts), responsible for the completion of certain All manufacturing work for products (zero, parts).
Production line and assembly line
The types of production lines are divided into product lines and component production lines according to the scope of the scope, and are divided into flow production lines and non-flow production lines according to the pace of the rhythm. According to the degree of automation, they are divided into automatic production lines and non-automated production lines.
The basic principle of a production line is to decompose a process of production iteration into several sub-processes. The former sub-process creates execution conditions for the next sub-process, and each process can be performed simultaneously with other sub-processes. In short, it is “functional decomposition, sequential in space, overlapping in time in parallelâ€.
The characteristics of the production line is that each process has a specific person to complete, step by step processing. Everyone does a specific job.
The significance of the production line
1. Improve the work efficiency of operators and equipment fixtures;
2. Man-hour consumption of single product, reducing costs (equivalent to increasing per capita output)
3. Reduce the number of products in process and truly realize "one stream";
4. To achieve unit production on the basis of a balanced production line, improve production strain capability, respond to market changes, and achieve flexible production systems;
5. Through the balance of production lines can be comprehensively applied to the program analysis, motion analysis, layout (Layout) analysis, handling analysis, time analysis and all IE techniques to improve the overall quality of the entire staff.
Production line classification
Plug-in production line:
Widely used in the electronics industry. The assembly and configuration of the production line plug-in line can be arbitrarily changed. The speed of the plug-in line can be used to adjust the required conveying speed with the variable-speed knob. The width can be at any time with the width of the circuit board. The fuselage is made of aluminum alloy. The hand-push plug line adopts the aluminum profile rail as the transmission medium. Therefore, the thread body friction is small, no noise, no need to add any lubricating oil, no pollution to the printed board.
Roller production line
Features: Wide range of products to be carried, with less restrictions; with the use of stoppers, it can realize the continuous, taktaging and accumulating functions of the product; the lifting and translation device can realize offline repair or detection of products without affecting The entire assembly line runs.
Belt type production line
Features: Lighter load bearing, less shape restriction; synchronous operation with the production line, it can realize the product's climbing and steering; with the belt as the carrier and conveying, the product can be smoothly conveyed with low noise; the light material or product can be realized longer Distance delivery.
Double speed chain conveyor production line
Features: The differential conveying line adopts double-speed chain traction. The tooling plate can be freely conveyed. The blocker is used to position the workpiece to move freely or stop. The workpiece can be automatically lifted at both ends, and the transition can be shifted laterally. It is also possible to install rotation (90 degrees, 180 degrees), special planes, inspection equipment, robots, etc. on the body or on the side of the body.
Packaging production line
Technical Note: Packaging production line with a lamp with fan packaging production line and lamp packaging production line, general with fan with fan packaging production line is widely used, simple operation. Mainly used in electronics factory, hardware factory, toy factory and some other packaging workshop. Sitting in the middle of the workbench with a conveyor belt. Improve production efficiency, greatly reduce labor, pay
Uses and features: The packaging production line is composed of cover-type adsorption corrugating machine, paper holder, glue applicator, double-sided machine, paper cutter, preheat roll, double bridge, and glue making machine. Its characteristics are high degree of automation, convenient operation and maintenance, high production efficiency, good quality cardboard, compact structure, beautiful appearance.
Production line development trend
1 Continue to grow to large scale. Large-scale includes several aspects such as large transport capacity, large stand-alone length, and large transport inclination. The length of the hydraulic conveying device has reached more than 440 kilometers. The length of the single unit of the belt conveyor has been nearly 15 kilometers, and there have been several "band conveyor lanes" that make up the connection between A and B. Many countries are exploring more complete conveyor structures for long-distance, large-capacity continuous transport of materials.
2 Expand the use of conveyors. Develop conveyors that can operate in high temperature and low temperature environments, corrosive, radioactive, and flammable materials, and that can transport hot, explosive, agglomerating, sticky materials.
3 to make the conveyor structure to meet the requirements of the single-machine automation control of the material handling system. For example, the trolley conveyor used for automatic sorting of parcels used by the post office should be able to meet the requirements of sorting operations.
4 Reducing energy consumption to save energy has become an important aspect of scientific research in transportation technology. The energy consumed for transporting one ton of material for one kilometer has been taken as one of the important indicators of conveyor selection.
5 Reduce the dust, noise and emissions of various conveyors during operation.
