“…a car which one can only start driving once the seat belt is buckled). Information embedding, as already extensively reported in the pokayoke and VM literature (Galsworth, 2005;Saurin et al 2012;Tezel et al 2015), is a means to ensure that only the desire action or behaviour happens. This can be directly translated and applied to module assembly in production to ensure (i) only the correct/allowed combinations among modules are performed and (ii) that the combination (or interface) of every two modules meets the defined tolerance requirements.…”

“…Poka-yokes are often used as complementary systems alongside statistical quality control in manufacturing to achieve quality at source and the zero defect ideal in production (Vinod et al 2015). They have been classified as symbolic, functional, and physical (Saurin et al 2012). In the latter case (physical poka-yokes), the contact surfaces of two modules are deliberately designed to allow only the correct assembly of modules (Shimbun 1988).…”

Product Modularity refers to the hierarchical partitioning of products into their constitutive components. This concept has been explored in manufacturing to ease product design, simplify production, and to efficiently provide variety. Efforts have been made to transfer this knowledge to the construction context (i.e. one-off products, temporary supply chain, production taking place inside the product), especially to support the latter goal: variety. Yet, it is argued that a re-conceptualization of building design and production is required for the successful application of modularization. That is, materials and components used to erect a building should be grouped (at least conceptually) as families of modules and work (production tasks) has to be structured according to such organization. This paper explores the synergies among Product Modularity, Tolerance Management, and Visual Management to improve and ease the understanding of such reconceptualization in design and production. It also examines patterns from the theoretical background of Design for Behaviour Change, and how these can be adapted to embed information in modules and present tolerance data in design drawings.

“…This creates a need to remove the possibility of human error from the system [16]. This system therefore has an internal poka-yoke type error-recognition system that recognizes an incorrect punnet before it is finished [21], and that is independent of lapses in the operator's attention span [22]. After the contents of the two complimentary punnets have been added together, the internal check-weighing function verifies that the net mass of the punnet is within specification, and a green go-ahead light is activated on the display.…”

“…Each scale dynamically adjusts its target mass and assists the packer by means of LEDs to achieve approximately the desired punnet mass. When a punnet with a mass outside the lower or upper limits is removed from the scale, the functional type internal poka-yoke [22] check-weigher locks the user interface, and a supervisor code must be entered to continue operation. …”

“…An external, independent check-weigher can be added to an existing system with minimal change to the infrastructure [22]. The check-weigher used in the evaluation is a modular system comprising a load cell-and-conveyor belt combination with control panel and controller, as well as a separate faulty package rejection unit to remove the punnets with out-of-specification mass.…”

Table Grape Punnet Packaging: The Influence of Check-Weighing

Most of South Africa's table grapes are exported to the EU and the UK. In recent years, prepackaged table grapes are now preferred in many European supermarkets. This increased demand has resulted in stringent quality standards, including the specification of punnet mass. Locally, table grapes are packed manually using seasonal labour, who often have limited formal education. Punnets must conform to upper and lower mass limits, but many deviations occur due to human and machine error. Check-weighing proved effective in reducing out-of-specification punnets, but human and machine errors were still problem factors. OPSOMMINGDie meeste Suid-Afrikaanse tafeldruiwe word uitgevoer na die Europese Unie en die Verenigde Koninkryk. Die voor-verpakking van tafeldruiwe in 'punnets' begin al meer voorkeur geniet by Europese supermarkte. Hierdie verhoging in aanvraag het gelei tot strenger gehaltestandaarde, insluitend 'punnet' massa. In Suid-Afrika word meestal gebruik gemaak van seisoenale werkers met beperkte formele onderrig om tafeldruiwe te verpak. 'Punnets' moet voldoen aan boonste en onderste massagrense, maar baie deviasies kom voor as gevolg van menslike-en masjienfoute. Geoutomatiseerde eksterne toetsweging lewer positiewe resultate ten opsigte van vermindering van oor-en ondergewig 'punnets', maar menslike-en masjienfoute bly steeds probleemfaktore. a a a a a a a a a a a a a a a a a 1 The author was enrolled for an MScEng (Engineering Management) degree at Stellenbosch University.
