Abstract

The present solution relates to transportation caps for components with cavities, in particular components containing small amounts of residual fluids. By integrating a transportation cap with a plug made of absorbent material, leakage to exterior sur-faces can be avoided when dismounting the caps. The solution is primarily intended for use when transporting and handling components in a production process.

Absorbent plug for transportation caps

ABSTRACT

The present solution relates to transportation caps for components with cavities, in particular components containing small amounts of residual fluids. By integrating a transportation cap with a plug made of absorbent material, leakage to exterior surfaces can be avoided when dismounting the caps. The solution is primarily intended for use when transporting and handling components in a production process.

BACKGROUND ART

A production process of vehicles involves transportation and handling of many types of components, where some of the components have cavities intended to contain fluids.  In a vehicle, the engine will for example contain engine oil and the gearbox will contain transmission oil. Other types of components with cavities are found within the brake system and hydraulic system.

The manufacturing or testing of such components with cavities earlier in the production process or at a supplier, will often result in small amounts of residual fluid being left in the cavity, since it is difficult to completely empty all fluid. The residual fluid may leak from the fittings of the component and contaminate the floor or other surfaces during transport or handling of the component. To prevent residual fluid from leaking it is a common use to cover the fittings with caps directly after manufacturing or test of the component, and remove the caps at final assembly.

If a component, when mounted, is oriented such that a fitting and its cap is facing downwards, the gravity will cause any residual fluid to flow towards the fitting and aggregate behind the cap. Arranging the component and its fittings differently may not be possible due to component function, manufacturing efficiency, ergonomic aspects or other reasons. In order to connect piping or another component to the fitting at final assembly, the cap needs to be removed first. When removing the cap, and if a significant amount of fluid is present, the fluid will leak and drop on surfaces below, such as the hands of an operator, the manufacturing floor or other components arranged underneath the leaking component. Hence, despite the use of protective caps, leakage occurs in production processes and causes various problems. One obvious problem is an increased risk for injury caused by slipping or falling due to a slippery floor. Another problem is contamination of the surfaces of other components, which is mostly not acceptable by quality standards. The practical way to handle the leakage is often to initiate cleaning activities which are associated with unwanted costs, potentially including a production stop, until the production environment or contaminated components have been cleared for use.

TECHNICAL SOLUTION

The present solution comprises the adding of an absorbent plug to an existing type of cap for a particular component. An existing cap in use may only need minor adaptations to enable integration with an absorbent plug. The solution may co...
