Production line layout refers to the matching, combination and distribution of different production equipment in the limited space of the workshop. Equipment determines the production scope of the enterprise, but for panel furniture, the types of equipment is less, the replaceability is relatively high, so it is very critical to match the different equipment to complement each other's strengths and weaknesses, and it can be said that the layout determines the production efficiency, the degree of flexibility and the potential for future upgrading and remodeling.

 

(1) Fully automatic continuous assembly line layout

 

This layout through the conveyor belt, conveyor rollers and other equipment to all processes in series, and as far as possible the use of automated equipment to replace manpower.

 

The difficulty of this layout is how to ensure that the production beat of each process is consistent, reducing fluctuations in the amount of equipment, so that the assembly line can not pause, less pause high-speed smooth flow.

 

The figure below shows a typical fully automatic continuous assembly line layout. The opening process is realized by the intelligent library system and AGV car to automatically load materials according to the production task.

 

Using the adsorption type robot to carry out the opening direction, the large-size residual material produced by the opening with the board together with the flow of the next process, small-size waste from the electronic saw waste exit directly into the waste conveyor belt.

Behind the unloading equipment is an automatic labeling machine, which prints and pastes labels according to the outgoing queue, and a code scanning device is set up after the labeling machine to confirm whether the labels are correctly pasted or not.

Several sets of opening equipment out of the plate after reasonable distribution of convergence to a conveyor belt, after the quality testing equipment, unqualified boards and large-size remnants together with the return of hedgehog frame stripping assembly line.

(2) Island type (unit type) layout

At this stage of customized furniture enterprises, the degree of flexibility and efficiency of individual equipment is difficult to balance, the overall automation and production costs are also contradictory.

For example, the above continuous assembly line layout of the workshop can not produce curved edges, edges and other shaped panels, the production of slots, open holes and other panels of low efficiency, and this layout of the size of the production of panels color range and process by the limitations of the production line design, when there are new products and new processes, the line's scalability is not high, so the island layout is still one of the necessary layout of the workshop of the customized furniture enterprises.

As shown in the figure below, the island layout emphasizes the staff's initiative, and the selection of equipment focuses on low-cost, specialized semi-automatic equipment to make up for the loss of efficiency caused by manpower.

The island layout divides the workshop horizontally into 4 main process areas according to opening, sealing, drilling, inspection and packaging, and there is a cache area before and after each process.

Semi-finished products cache area can be used with a mat with the roller for transportation, the transfer between the roller rely on a cart with a roller and rotary reversing structure to complete the process front semi-finished products cache area can be slightly smaller than the back end of the process cache area.

In order to facilitate the production tasks and progress tracking, the island table layout can also be vertically divided into several different lines according to the product structure, production difficulty and other factors.

The most basic division is in accordance with the plate shape is divided into rectangular and curved type, rectangular line body using electronic saw equipment to open the material, single-sided straight edge sealing machine sealing. Curve line body using CNC machining centers to open the material, manual curve edge sealing machine sealing.

 

(3) Semi-automatic hybrid layout

As shown in the figure below semi-automatic hybrid workshop layout for the lack of large amounts of money to establish a continuous assembly line layout of the workshop is a good complement to the enterprise, it is relatively low cost to achieve high speed and stability, quality and reliability of production, but also to maintain a greater range of production.

This layout uses the same back-end infeed electronic saws and intelligent stand-up storage system for the opening process, but with manually assisted changeovers, and remnants are collected by the opening process and handed over to the rest of the shop for reuse.

Each electronic saw is connected to a buffer rack to offset the uncertainty of the manual rhythm of operation. The opening, sealing and drilling processes are also connected by conveyor belts, conveyor rollers and other equipment, but no automatic quality control equipment is set up; instead, after the drilling process is completed, access to manual sorting and quality control and packaging.

 

The selection and combination of equipment is the basis for the realization of the concept of Industry 4.0, with the integration of the custom industry, the production practices of large enterprises will also force the equipment suppliers to add more adaptive to the needs of the times on the traditional equipment, the future form of the production line will be more diverse.

If you want to know more about the industry information and cutting-edge products, China Home Expo, which gathers a lot of furniture brands, is surely the right choice for you. CIFF Shanghai Expo 2024 will be grandly unfolded from September 11 to 14, 2024 at the NATIONAL EXHIBITION AND CONVENTION CENTER (SHANGHAL HONGQIAO).
