Sofa and improved production technology

is the main furniture. Beautiful shape, color harmony, exquisite workmanship of the sofa, not only is the ideal resting坐具, but also beautify the indoor environment plays embodies the aesthetic pursuit of the master bedroom role.
At present, most of sofa production enterprises is relatively small, sofas production process technology is also less, the majority of technology operations using traditional manual production methods. Not long ago, the number of foreign clients Zhejiang ordered a group of manufacturing enterprises sofa sofa, and then to the factory tour, when the sofa watching the process of , amazed. Foreign businessmen said: “The sofa is so beautiful in such a simple production environment, it is too amazing. It was a miracle!” This is reflected from one aspect of many of our sofa manufacturing enterprises difference between production conditions and production processes of the original. Sofa improve production technology, improve the sofa production techniques, technology, equipment levels are sofa manufacturers to seriously ponder.
1 sofa structure
Modeling in accordance with the sofa, the sofa is currently divided into two major types of . Classical style sofa in general have adopted some elements of the traditional style, using traditional technology structure, so the structure is rather complicated. Sofa over the exposed parts of such common sculpture, mosaics, painted, decorative finishing processes, such as processing, production line of its long, high technical requirements. Modern style sofa production process is relatively simple, extensive application of modern technology of new materials, production processes of its line of short, easy to scale production.
Sofa mainly by the framework filler fabric three constitute the majority. (1) the framework of the composition of the sofa main structure and basic shapes. The framework of , steel, wood-based panel, such as medium density fiberboard, now mainly of medium density fiberboard. Framework to meet the design requirements and strength requirements. (2) filler on the sofa comfort plays a decisive role. Traditional filler is brown silk, spring, and now commonly used in a variety of functions, the foam plastic, sponge, synthetic materials. Filler should have good flexibility, anti-fatigue, long-life. Sofa in different parts of the filler loading, comfort requirements are different. Filler performance, great price difference. (3) fabric texture, color determines the grade of the sofa, the current varieties of fabrics is an array, with the scientific and technological progress, will become more and more species-rich fabrics.
The general structure of the traditional sofa (bottom-up): Framework - wood - spring - the bottom of gauze -mattress- sponge - in bags - outside. Kits. The general structure of the modern sofa (bottom-up): Framework - elastic band - the bottom of gauze - sponge - within the bag - jacket (Figure 1). This shows that the modern sofa production process than the traditional sofa omitted workers a fixed time-consuming springmattressShop processes.
2 sofa production process
Sofa production is characterized by many kinds of materials used, material differences, and create the framework of wood, steel, wood-based panel, painting, decorative items, etc.; filled with sponges, foam plastic, elastic, non-woven fabric, springs, etc.mattress; production jacket with a cloth, leather, composite materials. Processing large-span, from the carpentry work, painting work, sewing the work of the industry to work in industry palpable fat. According to the professional division of labor, the principle of efficiency, will be divided into 5 sofa processing section: framework section, the main framework for the production of sofa; exterior section, mainly the production of components ; lined section, the preparation of various types of sponge inner core; jacket section, cutting sewing jacket; assembly (palpable Paper) section for each of the pre-section of semi-finished products, with accessories, assembly into a complete sofa products (Figure 2).
Different sofa manufacturing plant of its processes are different, small business lines of segregation of duties coarse, medium and large enterprises in greater detail the process division of labor, specialization, division of labor will help improve work efficiency and ensure product quality stability.
3 production profile
3.1 batching process
Most timber frame sofa plates, used to open feed linear cut-off saws saw the plates, small businesses are using a circular saw cut-off saws, band sawing curved plate. Sofa frame timber, medium density fibreboard may be due to medium-density fiberboard with a format, and the material advantages of the high rate of curved parts particularly notable. At present, all kinds of MDF with the fasteners, connectors very good performance. The market closed many of formaldehyde, formaldehyde to capture the chemical products in the framework of the surface of MDF spraying, will be rid of formaldehyde problems. Come forward the framework for solid wood, handrails, decorative pieces, these parts and components of high surface quality requirements, process complexity, and some needed to bend wood, and some require special process, these components are basically the processing of solid wood furniture line will no longer be discussed.
Clearly the correct ingredients alone, nesting map, curved parts of the template, it is reasonable material to be used as the main measures to improve work efficiency.
Framework 3.2 assembly
Will be good preparation sheet, bending pieces方材into the box, and sealing the floor. Should be routinely collected for the sofa group summary box fasteners, cleverly chosen fasteners information, the framework for the assembly can play effectively. Sofa made of a framework should pay attention to the quality of production to meet the requirements of the framework of size, size of the error to the assembly (palpable Paper) processes cause trouble. The strength of the framework to meet the requirements in the framework of the current structure of the sofa to experience, in fact, can be reduced by optimizing the framework to deal with the use of materials or further enhance the strength. Frame structure of the process should also pay attention to, it is necessary to facilitate the follow-up processes. The framework of the surface to be light throughout the treatment, Deburring and acute angle, so as to avoid the follow-up processes to stay hidden.
3.3 sponge preparation
According to the specifications is expected to ask the size, line, cut sponge, for the shape of complex sets of the CD to be the sponge should be accompanied by nesting single and templates to facilitate construction.
Paste Framework 3.4
In the framework of elastic nails - nails gauze - adhesive thin or thick sponge for palpable processes in preparation for skin, reduce operating processes palpable amount of skin. This process of elastic specifications, quantity, pulling the value of cross-order must have the corresponding requirements, these parameters will affect the comfort of a sofa and durability.
3.5 jacket cutting
According to single-ingredient requirements, according to a model for cutting. For natural hides by Zhang checks to avoid injuries, defects. Synthetic materials may be stacked cut electricity cut and reasonable use of precious natural hides, the volume of timber optional, and put an end to大材小用. Cut jacket is a control point of the cost of production.
3.6 jacket sewing
Cutting a good coat, according to different technological requirements in different sewing sewing equipment into jackets, cushion covers. At present, many varieties of sewing equipment, sewing thread sofa is also evolving.
3.7 assembly (palpable Paper)
To paste a good framework, a processed, the jacket, a variety of accessories, spare parts assembled into a sofa. General process is there in the sticky sponge within the framework of the nail set, and then put on jackets and fixed, and then fitted with decorative pieces, nails at the end of cloth, loaded legs.
3.8 test storage
Products after passing inspection packaging, warehousing.
4 sofa measures for improvement of production technology
4.1 on the sofa can be used in the production of modular technology
Despite great changes in style sofa, through the analysis of classified and identified the basic elements, it is necessary to establish the standardization and serialization of the concept of production to minimize the number of parts specifications. Change a model equipped with a sofa (from the framework of the jacket) parts and components, one-on-one situation are not interchangeable. The realization of the fundamental pieces of the election integral parts, the basic thing remains unchanged and swap in a series with the election with the sofa accessories change models.
4.2 to enhance the degree of specialization of production sofa
At present, metal sofa high degree of specialization, professional factory sofa factory in accordance with the diverse needs of manufacturing a variety of hardware such as connectors and fasteners. Decorative pieces of wood sofa, as well as the framework for solid wood exposed by professional plant production, this will help improve the overall quality of the sofa frame and improve the degree of specialization sofa factory.
4.3 improve the sofa production mechanization level
Is currently used in the production of professional sofa machinery have elastic tensioning machine, filling machine, cutting machine, Paper palpable platforms, but its species, size, quality can not meet all needs, sofas and furniture manufacturers can machinery manufacturing enterprises professional equipment to develop the sofa, in fact, is also a big sofa machinery market.
4.4 sofa production software development
Sofa designs currently available mapping software modeling plans, structural plans, but the sofa started lofting coat, sponge off the degree to determine the size or experience to complete by lofting master. Lofting now compare the accuracy of the general poor, often through the ultimate test as amended, filling foam sponges and palpable skin to control when the plumpness of their sofa. As the result of product inconsistent gestures operatives, should be gradually on the sofa in production processes to enhance the accuracy, the elimination of uncontrollable factors, the achievement of controllable production.
4.5 to develop parts of the sofa
In the assembly (palpable Paper) process to constantly flip operatives bulky sofa, transform a different position, but not always so low上劲position operations, labor-intensive, low-efficiency, long-term operation of the physical injury . The use of take-off and landing, rotating multi-function table is one of the ways. At present, some manufacturers are experimenting with sofa parts production sofa. Parts of the sofa is more conducive to production, assembly, storage, transportation, this is a breakthrough in the production of sofa.
