The modular tool cabinet should be disassembled before transportation according to the principle of "disassembly by functional unit" to maximize the use of space. First, the overall modular tool cabinet is decomposed into independent basic modules, such as drawer units, modular tool cabinet door units, frame columns, etc. Each unit is classified and stacked according to specifications. For example, the drawer module can remove the internal partition board so that the drawers are nested with each other, and the nesting depth does not exceed two-thirds of the drawer height, which saves space and avoids the drawer panels from squeezing each other. Long strips such as frame columns are arranged in parallel and fixed into bundles with strapping tape. The number of each bundle does not exceed 6 to prevent mutual collision and deformation during transportation. This splitting method can reduce the packaging volume by about 40%.
The disassembled parts need to be graded and packaged, and the appropriate packaging materials should be selected according to the degree of fragility. For precision parts such as drawer slides and locks, first wrap them with 3-4 layers of bubble film to ensure that the corners are completely covered, and then put them in a hard plastic box, and fill the box with pearl cotton to fill the gaps to prevent shaking and wear. The frame and other load-bearing parts are wrapped with wrapping film as a whole, and the overlap rate is maintained at 50% during wrapping to form a tight protective layer. The outer layer is covered with a waterproof woven bag to cope with the humid environment during transportation. For fragile parts such as modular tool cabinet door glass, customized foam boxes are required to be used separately. The preset grooves in the box fix the glass position. The foam thickness is not less than 5cm to ensure that it will not be damaged when falling from a height of 1 meter.
The stacking design of the packaging must take into account both space utilization and stability. The frame columns in the basic module can be placed vertically at the bottom of the transport box to form a stable support, and the drawer units are stacked horizontally on top. A layer of corrugated cardboard is placed between the drawer units to enhance the cushioning effect. The modular tool cabinet door units must be placed vertically and tilted, with the tilt angle controlled at 15°-30°. Adjacent modular tool cabinet doors are separated by sponge strips to avoid surface scratches. The center of gravity of all stacked components must be kept in the center of the transport box, and the stacking height must not exceed 80% of the height of the transport box. Space is reserved on the top to place small accessory boxes. Through reasonable layout, the loading rate of each transport box is increased to more than 90%.
Separate packaging of accessories and main parts can reduce mutual wear. Small accessories such as screws, handles, and dividers are packed into different sealed bags according to their types. The names of the accessories and the corresponding modules are marked on the outside of the bags. Then they are put into a hard tool box. The tool box is divided into multiple areas with partitions to prevent the accessories from mixing and colliding. The tool box is fixed in the corner of the transport box, and the gaps around it are filled with foam blocks to prevent direct contact with the main parts. For components such as slide rails that need to be used with modules, the "attached with the module" method can be adopted, and they can be fixed to the non-working surface of the module with tape to avoid loss and reduce the space occupied by separate packaging.
The specification selection of the transport box needs to match the size of the split parts. Foldable corrugated boxes or wooden frame boxes are used. The box size is determined according to the length, width and height of the largest component, and a buffer space of 10-15cm is reserved. Wooden frame boxes are suitable for long-distance transportation. The frame joints are reinforced with angle irons. 3cm thick EVA foam is laid in the box. Grooves are cut on the surface of the foam according to the shape of the components to achieve modular fixation. Corrugated boxes are suitable for short-distance transportation. The box body is made of five layers of corrugated cardboard with a load-bearing capacity of not less than 50kg. The box is reinforced with strapping tape in a "well" shape. The tension of the strapping tape is kept consistent to prevent the box body from cracking.
When splitting the package, it is necessary to make good markings and protective reminders to facilitate standardized operations during transportation. Each packaging unit needs to be posted with signs such as "upward", "lightly placed", and "stacking limit". The marking position is selected on both sides and the top of the box body and is clearly visible. For the packaging of precision parts, the words "contains vulnerable parts, please do not press heavily" are additionally marked to remind the loading and unloading personnel to pay attention to the operating force. A split list is placed inside the package. The list records the name, quantity and corresponding position of the parts in detail to facilitate assembly and verification after receipt. At the same time, the assembly sequence prompts are noted on the list to facilitate subsequent installation.
The fixing measures during transportation are the last line of defense to avoid damage to the parts. During loading, the transport box needs to be fixed to the vehicle compartment. Nylon cable ties are used to connect the box to the guardrail of the compartment. The spacing between the cable ties should not exceed 80cm to ensure that the box does not move during sudden braking. Anti-skid mats are laid on the bottom of the compartment with a friction coefficient of not less than 0.6 to prevent the box from sliding and colliding. For long-distance transportation, desiccant should be placed in the compartment, with 200g of desiccant per cubic meter of space, and the internal humidity should be controlled below 60% to prevent metal parts from getting damp and rusting. Regularly check the integrity of the packaging during transportation, and repair any damage in a timely manner to ensure that all parts arrive safely at their destination.
