"Poka-yoke" systems: an indispensable aid in the process of assembly

The term "poka-yoke", which is widespread in our companies, is closely linked with the principles of LEAN PRODUCTION.

Fiam, attentive to the development of technologies to improve production processes, has designed and produced entirely a device that is installed on the assembly lines in combination with air screwdrivers, makes it impossible the error and incorrect positioning or absence of screws and immediately notify the results of assembly operations.

Here a case of production, solved for a major company in northern Italy that manufactures components for the plumbing and heating industry: it ''was set up an assembly line with 20 workstations with screwdrivers 15C installed on telescopic arms in carbon.

The air shut-off screwdrivers are equipped with pneumatic pick-up signal (ported) and are connected to the unit TOM, the poka-yoke device Fiam that brings many benefits in industrial assembly processes because:

- Identifies the scrap before it becomes an irreversible waste

- It halts the assembly line in order to prevent the waste reaches the end of cycle, unnecessarily increasing manufacturing costs.

- It allows fixing the mistake and undertaking corrective measure.

- It relieves the operator from monitoring the process step by step, with great benefit for the quality of the final product.

The system allows skipping the post process controls on the assembled components

as occurs in real time the status of the tightening process and ensures reliability regardless of the operator''s ability. A practical and inexpensive system (anti-error): at tightening end, the operator is warned about the outcome thus can quickly move to the next assembly job. All elements necessary to ensure a ''high continuity of work and work cycles faster.

TOM is equipped with 2 display: to the operating status and the number of screws to be tightened. 3 LEDs and 4 types of beeps allowing the operator quick checks and explicit.

With the menu in 5 languages, TOM is easy to use: through a SINGLE PROGRAM or a SEQUENCE

of PROGRAMS (up to 8) with 99 tightenings each.

TOM can manage up to 8 tools (used by one operator) with different setting, moreover it can enable one tool at a time according to programmed sequence.

It discriminates the untightenings by decreasing the count of the performed tightenings.
