9. Enclosure / shell

Subpages

• Protective covers (plunger, drivetrain) (updated 2026-03-20) — CAD figure from shared enclosure gallery.
• Overcentered hinges (updated 2026-03-20) — CAD figure + discussion; linkage/bracket concept.

Introduction

The Enclosure / shell (Subsystem 9) guards operators from moving parts — belt/pulleys, plunger drive, and peeler assemblies — while allowing fast access for cleaning, service, and inspection. It consists of two main covers (plunger-side and drivetrain-side) mounted to the frame using overcentered hinges that hold each lid in a stable open or closed position. Three lid safety interlocks (coded magnet switches) feed into the controls and electronics subsystem to prevent operation when any cover is open.

Colour key & components

Two main covers + overcentered hinges. Feeder, drivetrain lid, and plunger lid all use overcentered hinges (open stay open, shut stay shut).

Figures

CAD views of plunger cover, drivetrain cover, and overcentered hinge mounting. Refer to Figure 1, Figure 2, etc.

Recommended figures (contractor clarity)

• Add figure: Interlock magnet targets — one diagram per lid (feeder / plunger / drivetrain).
• Add figure: Cover open collision check — full stroke with covers in service positions.
• Add figure: Spring-assisted hinge tuning — force vs angle once WIP hinge is finalized.

Discussion

Interfaces

• Plunger cover — overcentered hinge to frame/feeder; protects core ejection plungers.
• Drivetrain cover — overcentered hinge to frame/feeder body; covers drivetrain.
• Feeder — also mounted with overcentered hinge; see Fruit intake system.
