Whether it is solid wood furniture or panel furniture, the batch processing process is the first process in the furniture production process, and it is also a very important process, which directly affects the material utilization rate, production efficiency and production efficiency of furniture production.
A flexible and experienced batching worker can remember up to five parts and sizes, which cannot meet the requirements of the modern furniture production process. The specifications of the selected sawing materials for traditional ingredients are mainly selected according to the existing materials of the workshop. The quality of the ingredients is fully grasped by the batching workers. The human influence factors are relatively large and the randomness is relatively large. It belongs to the typical hand workshop type ingredients, and the modern production mode. Ingredients require the elimination of human influence and the removal of uncertainties as much as possible.
The key to the slab furniture ingredients is to increase the yield, that is, using the discharge map to open the material. There is no discharge map in the traditional batching process. How to open the material depends on the understanding and experience of the batching workers on the panel furniture parts. The human factors play a leading role and are not suitable for the modern production mode.
The modern furniture production model has undergone fundamental changes compared to the traditional production model. From manual workshops or large-scale production methods to new production models that change with changes in the furniture market and changes in consumer demand. People's demands for furniture are becoming more and more individualized. Manufacturing companies must meet this individualization requirement for their own survival. However, furniture companies have become accustomed to profit from large-scale production methods, which has resulted in many varieties and small batches. The contradiction between the high-level demand for furniture and mass production. An effective way to resolve this contradiction is to adopt advanced manufacturing techniques and management. Production models and technologies such as Flexible Manufacturing, Group Technology, Mass Customization, and Lean Production have emerged.
Many industries at home and abroad, such as machinery, automobiles, electronics, and chemical industries, have been using these advanced production models to organize production or manage production, and have achieved remarkable results. In the domestic furniture industry, some large and powerful enterprises have begun to try flexible production, group technology and mass customization. The reason for the attempt is to adapt the production of the enterprise to the needs of the furniture market, to solve the need of traditional production to adapt to the furniture market, and to resolve the contradiction that cannot be solved by the traditional production mode. To achieve a modern furniture production model, the corresponding batching process is no exception.
Furniture manufacturers are most concerned with production efficiency, production efficiency and material utilization, all of which are directly related to the flexibility of the batcher. The batching process is a key process in the furniture production process, because it is the beginning of the entire furniture production machining process, which is equivalent to the cutting of the garment process, so it determines the efficiency and rise and fall of a furniture enterprise.
The principle of the ingredients: 1 according to the furniture parts for the material requirements of the ingredients; 2 according to the raw material (board) and the furniture parts wool specifications of the size of the matching relationship.
Ingredients: 1 first horizontal and vertical; is a common method used in the production of solid wood furniture, occupying a small area of ​​the factory, but the material utilization rate is low. 2 first vertical and horizontal; the yield is relatively high, but the occupied plant area is large, and the wool width specification is relatively simple. 3 Underline saw: Mainly suitable for curved parts, the purpose is to increase the yield. 4 After shaving, carry out 1 or 2; it is mainly suitable for the furnishing of furniture parts with high surface quality requirements for furniture parts. After the glue is glued, the line is re-scored; the main purpose is to increase the yield of the ingredients of the curved parts.
Operation mode: The production department in the furniture enterprise issues the production task to the batching group → the batching group arranges the production task of each worker or the production task of each station according to the task → the worker completes the production task by experience → the statistician or the team leader Statistical production completion → Production department summary. Quality inspection is interspersed throughout the production process.
Batching equipment: Common batching equipments are hoisting saws, precision table saws, cantilever circular saws, ordinary circular saws, multi-saw circular saws, band saws, wind shears and other equipment. The processing precision and efficiency of these equipments are relatively low, and the labor intensity of workers is relatively large, which is not conducive to continuous modern production and cannot truly meet the needs of furniture enterprises.
2.2 Panel furniture traditional way ingredients
Commonly used equipment is precision push table saw, ordinary electronic cutting saw (vertical or horizontal) or circular sawing machine. The traditional batching process of panel furniture is based on the experience of workers. Opening large or long materials, and then opening small or short materials, the randomness is very large, so the yield is unstable and low, because there is no optimized discharge chart to guide the discharge operation.
In summary, it is not difficult to see from the operation mode that the artificial factors of traditional ingredients dominate, and the randomness is also quite large. According to the ingredients plan, the quality of the raw materials is also uneven, resulting in too many variables. The ingredients are more flexible, but there are more uncertain factors, and production is more difficult to control. It can be seen from the batching equipment that the processing precision of the ingredients is low and the batching process can be controlled poorly. Although the traditional batching process is flexible, it is an uncontrollable flexibility, but it consumes a lot of time, people and venues, and the production efficiency is very low, which is not suitable for the requirements of modern production.
3.1.1 Modern ingredients for solid wood furniture
The modern production method of solid wood furniture requires that the ingredients are produced in a flexible, efficient manner and can provide individualized ingredients. In other words, the specific indicators considered in the batching process refer to factors such as product specifications, grade requirements, yields, and economic benefits. It is unrealistic to require operators to consider the above factors in traditional ingredients, because an experienced batching worker can only remember limited part specifications at a time, let alone not integrate other factors, only with the help of a computer. Achieve comprehensive optimization work.
The flexibility of the production of ingredients means that the defects of the plates (mainly the distribution of thrift) vary widely, but they can all be processed according to the same batching process, and the products after the ingredients can also meet the needs of different furniture parts. Unlike the flexibility of traditional batching processes, it is a controllable, orderly flexibility.
The high efficiency of batching production means that the production order can react quickly when the production order changes. When the production quantity and production requirements change, the batching production can be adjusted in time. If the order is inserted or the delivery date changes, the quality and quantity can be completed on time. The production order is the same as the normal ingredient production, that is, the batching process and equipment arrangement are relatively stable.
Personalized ingredients for ingredient production: Furniture companies may have different business strategies. If some orders emphasize the high quality of the furniture, then the quality requirements of the parts are also high. Therefore, the grade of the board should be considered in the batching; sometimes the order quantity is relatively large, but the furniture grade is low, and the batching scheme focuses on the output. Usually, furniture companies pursue comprehensive economic benefits, that is, ingredients will be compounded according to the highest output value.
Compared with the traditional batching process, it is not difficult to see that the above requirements cannot be fully implemented in the traditional batching process, but the modern batching process can be realized because the modern batching process is based on computer information and is stabilized by the process and equipment. Requirements for changes in complex raw materials and furniture parts.
3.1.2 Solid wood furniture modern batching equipment
According to the modern ingredients requirements of solid wood furniture, it can be seen that the modern batching process is completely different from the traditional batching process. This fundamental shift is done by a core device, which is an optimized cut-off saw.
Other equipment mainly includes:
Multi-blade circular sawing machine: For the wide-width cutting of the plate; if the saw blade is sawed, it is beneficial to the subsequent processing, such as more accurate positioning and less trimming work.
Trimming saw: For the shorter length of the square material after the superior sawing, trimming, preparing for the open finger shape. The widened wool is processed into wool that meets the requirements of the part.
Open finger machine and extension machine: mainly to complete the short-term task of short materials.
Double-sided planer: For the length of the square material, the processing reference surface is prepared for the puzzle.
Plate picker: multiply the length of the wool according to the requirements of the furniture parts.
Preferably, the saw is capable of optimizing the dosing regimen according to the requirements of the production task, and then cutting the equal width of the square material into square pieces that meet the production requirements. It is controlled by PLC (single board machine), with analysis, optimization, statistics and other functions, its processing accuracy and production efficiency are much higher than manual ingredients, and can meet the customer's individual requirements to achieve the best ingredients. If the raw materials are more frugal, the more parts that need to be compounded, the more the advantages of the preferred saws can be displayed, because the factors of the coffin ingredients need to be considered, and the manual ingredients cannot be comprehensively considered and efficiently completed. Preferably, the computer system of the saw has an optimized dosing scheme function, so it is preferred that the saw can substantially eliminate the influence of human factors and easily complete the modern ingredient production task.
The specific functions of the preferred saw are as follows:
(1) Production optimization: The preferred saw computer system uses a method compared with the sawing list (production task list) to analyze each piece of the plate to maximize the production rate of the plate.
(2) Value optimization: By setting the corresponding value of the different specifications of the sawing list in advance, the computer system of the sawing machine can analyze each piece of the plate and create value according to the length of the plate produced, and optimize the length proportion composition. Finalize the ingredient plan for maximum value, at which point production may decrease.
(3) Quantity optimization: The result of the batching of this model is divided into main and auxiliary products. The main product is wool that meets the furniture production, and the by-product is a short square material that needs to be lengthened or assembled. This mode can also be formulated in terms of optimal stock or timely production. At the end of each working day, the length of the sheet is balanced according to the requirements of the ingredient list.
(4) Selective search: In order to optimize production, value and quantity, it is preferred that the saw computer system can search conditionally, such as searching for short plates or plates with missing edges, and can calculate the results from the search results. Joint production.
(5) Strong flexibility: It can optimize up to 16 different widths and 200 different lengths of plates. It can identify up to 8 grades and find the best solution of different grades. At the same time, it can also meet the specifications and quantity of the plates. Factors such as benefits.
(6) High machining accuracy: It is preferable that the saw has a machining accuracy of 0.8 mm, which is safe because it is mechanically operated automatically. It is very dangerous to achieve this precision with traditional manual ingredients, and the productivity is extremely low.
(7) Wide processing range: It can process all kinds of plates, including ultra-long plates. After processing, the saws can be classified according to their length.
(8) High production efficiency: It is preferred that the saw feed mechanism is a stepless speed control belt controlled by a computer, and the feed speed is extremely fast. Preferably, the saw completes a cutting cycle time of only 0.25 seconds, and the yield is quite amazing.
(9) Powerful: The saw can provide a complete, detailed sawing plan and product statistics report. The ingredient plan input and information report are realized by Microsoft Windows 2000 network, or can be set by a single machine. Analysis of material utilization and waste rate, total cutting length and surface area and processing of the net surface and other indicators are recorded and counted by computer.
(10) Savings: It is preferred that the saw has high production efficiency and high degree of automation, so it can save a lot of staff preparation time in the workshop and office, thus improving the work efficiency of the personnel. It is preferred that the sawing order is clear and accurate, reducing the probability of occurrence of errors, thereby reducing waste, and at the same time, fully utilizing the trimming material and improving the yield.
3.1.3 Modern ingredients for solid wood furniture
There are two main types of modern ingredients for solid wood furniture:
For large-size parts (mainly the cross-sectional dimensions of parts), the material-cutting scheme of the specification material is mainly used, that is, the cross-section specifications of the raw materials are basically matched with the cross-section specifications of the wool materials, but the length is the multiple of the wool material. can. Such a compounding scheme is used for making large bed columns such as rubber wood specifications.
Second, for small-size plates or small-size square ingredients, the following processes can be used:
Plate → grading → split (multi-saw circular sawing machine) → cross-section (preferably saw) → trimming → open finger 榫 → joint length → create datum plane (double planer) → glue → glue fight (spelling Board machine).
The arrangement of the core preferred saw in the above process is as shown above. Preferably, the saw processed product can be divided into: one is a wool which meets the requirements for furniture production; the other is a short material. All processed products are classified by length, and the short parts of the product are processed into jigsaws by finger joints. The panel is defect-free and its properties are similar to natural sawn timber, but better in shape and dimensional stability than natural wood. Through the stable process and equipment, it can fully meet the actual needs of furniture parts, and demonstrate the flexible side of the modern batching process. However, because its object is a specific manufacturer, it has a strong pertinence.
3.1.4 Modern ingredients of solid wood furniture
3.1.4.1 Modern batching process is flexible
Compared with the traditional batching process, the flexibility of the modern batching process is orderly. The specific expression is that the modern ingredients can adapt to the processing of multi-standard, multi-grade raw materials, and can fully meet the requirements of multi-standard and multi-level furniture parts, and can provide several A personalized ingredient plan. The flexible characteristics of the batching process help to resolve the contradiction between the market needs of small batches of furniture and mass production.
3.1.4.2 Modern batching process has high productivity and high utilization rate of sheet
Compared with the equipment in the traditional batching process, it is preferred that the saw has higher processing precision than the traditional cross-section circular saw, and the sawing precision is preferably within 0.8 mm. In addition, the saw is automatically controlled, and the error is smaller than the manual positioning of the conventional manual ingredients. In addition, the sawing cycle time is 0.25 seconds, so productivity, processing accuracy and yield are also high.
3.1.4.3 Modern batching process management mode informationization
The modern production model has changed and its management model has changed. Traditional production methods mainly use empirical data. Conservative estimates to manage ingredient production, such as the estimation of the empirical value and then arrange the daily production, the completion of various parts is also based on manual statistics to draw conclusions, this cycle is too long for modern production mode. If a preferred saw is used, it can perform statistics and analysis by itself, and the enterprise computer server is directly connected, which can obtain processing instructions from it, and can also feed back statistical data and tables, saving a lot of manpower, material resources, and accuracy.
