Problems solved by technology
[0005] (1) Manual or semi-automatic spreaders are used to stack and stack plywood or polyurethane foam boards coated with glue layer by layer, which has high labor intensity and low production efficiency
[0006] (2) Misalignment between layers is unavoidable in manual assembly. Once a misalignment occurs, it is mostly corrected by hand or with the help of simple molds, and the manufacturing accuracy is difficult to effectively control;
[0007] (3) Occasional factors of manual operation disturb the overall rhythm of the entire production system, resulting in a backlog of parts to be assembled on the assembly line, seriously affecting the unity and coordination of the entire production system

Embodiment 1
[0070] The structure of the insulating box 40 as L03 or L03+ form is respectively as follows Figure 1-Figure 5 Shown, among them, the structure of K1 box type see figure 1 and image 3 As shown, it includes No. 1 board 41 (plywood), No. 2 board 42 (polyurethane board), No. 3 board 43 (plywood), No. 4 board 44 (polyurethane board) and No. 5 board 45, which are sequentially compounded from bottom to top (plywood), the four corners of the No. 2 board 42 are equipped with wooden right-angle splints 46. The structure of K2 or K5 box type is as follows: figure 2 and Figure 4 As shown, compared with the K1 box type, No. 4 plate 44 and No. 5 plate 45 are omitted, and other structures remain unchanged.
[0071] The above gluing assembly process can be found in Figure 5 ,Specifically:
[0072] The first step is to assemble the bottom parts. At this time, the upper surface of the No. 1 plate 41 is glued to form the No. 1 glue-coated surface 51, and the No. 2 plate 42 is not glu...

The invention relates to a box body assembly system for a polyurethane insulating box for liquefied natural gas. The box body assembly system comprises an insulating box assembly station, a material conveying mechanism and an upper-layer part conveying mechanism, wherein the insulating box assembly station is used for assembling a bottom-layer part and an upper-layer part to form an insulating box; the material conveying mechanism is used for conveying the bottom-layer part to the insulating box assembly station and feeding out the insulating box which is accomplished from the insulating box assembly station; and the upper-layer part conveying mechanism comprises an upper-layer part conveyor line arranged beside the material conveying mechanism, and an upper-layer part turnover device forbearing the tail end of the upper-layer part conveyor line and turning over the upper-layer part conveyed in place to the insulating box assembly station to assemble. Compared with the prior art, thebox body assembly system realizes high-reliability precise mounting and the like of the insulating boxes of various box type structures.
Description
technical field [0001] The invention belongs to the technical field of box body assembly, and relates to a box body assembly system for a polyurethane insulating box used for liquefied natural gas ships. Background technique [0002] The reinforced polyurethane standard insulation box is the core component in the containment system of a large liquefied natural gas film type LNG (Liquefied NaturalGas, referred to as LNG) ship. In the NO.96 containment system, the reinforced polyurethane standard insulation box includes In the form of L03, L03+, etc., a film-type LNG ship with NO.96 containment system needs 20,000 N096-L03+ series reinforced polyurethane standard insulation boxes; the reinforced polyurethane standard insulation boxes are highly standardized and highly The workshop is prefabricated, the process is complex, and the manufacturing precision is high; improving the automation of the insulation box is the key to improving the production efficiency of the insulation b...
