Monitor demand
Track-full, low-level, part-present and downstream-ready sensing.
Controls and line integration
Reliable feeding ends at a defined machine interface.
Sensors, accumulation, escapements, PLC logic and guarding are coordinated so the feeder responds correctly to real downstream demand.
A feeder is successful when the correct part reaches the next process at the agreed rate, datum and timing.
Define the hand-off
Position, pitch, timing and permission.
The final output condition must be measurable. A statement such as “parts fed correctly” is not enough to design the escapement or prove the interface.
- Accepted orientation and datum
- Discharge height and direction of travel
- Part pitch and presentation tolerance
- Pick-up or insertion position
- Ready, request, permit and fault signals
- Response to downstream stop and restart
Control architecture
Demand-led movement with a stable buffer.
The objective is not to run every drive continuously. It is to maintain the right amount of correctly presented product at the interface.
Coordinate motion
Start, stop and speed logic across lift, track and escapement.
Present one part
Mechanical or pneumatic escapement isolates the required output.
Expose status
Run, low level, starved, fault, interlock and production information.
Safety, access and recovery
Designed for the people who operate and maintain it.
Safe production includes routine loading, observation, format change, jam recovery, cleaning and maintenance—not only normal automatic running.
Guarding boundaryDefine which moving parts and transfer points are protected by the feeder or surrounding cell.
Access strategyDoors, interlocks, lift-off covers, observation panels and tool-free routine access where appropriate.
Jam recoveryClear method for isolating energy and reaching expected intervention points.
Format changeSettings, adjustable guides, change parts, recipes and verification of correct setup.
Site standardsControls platform, electrical standard, colours, components and documentation requirements.
Scope boundaryMechanical, electrical, software and safety responsibilities at every interface.
Handover
Evidence and information that support production.
The documentation scope is agreed with the project and can include operating, maintenance and acceptance information.
Trial & FAT records
Known sample set, test condition, sustained output and agreed intervention record.
Controls information
I/O, interface description, alarms, operating states, settings and backup requirements.
Operation & maintenance
Loading, recovery, changeover, routine checks, wear parts and maintenance access.
Straight answers
Integration and controls questions
Yes. The interface can use hardwired signals, fieldbus or an agreed controls architecture. The final method depends on the customer standard, scope boundary and receiving machine.
Track-full and demand sensors pause the lifting and orientation functions while preserving an appropriate buffer. Restart logic is developed to avoid flooding, starvation or double release.
Sensors or vision can verify presence, orientation, count or selected component features. Reject handling and proof of inspection should be defined as part of the acceptance criteria.
Guarding, access and safety interfaces can be included in the supplied scope. The boundary with the surrounding machine and the final site risk assessment must be agreed clearly.

Define ready and available as different conditions
The feeder can be healthy and ready to run while no accepted component is yet present at the pickup point. Distinguish equipment readiness, buffer level and a part available for release in the interface brief. Identify which side owns each signal and what the other machine is permitted to do when it changes. This prevents the receiving process from treating an enabled feeder drive as proof that an assembly component is actually in position.
Use a state review before controls are built
Walk through startup with an empty track, normal demand, a full buffer, a downstream pause and demand returning. For each condition, describe the intended lifting, track and escapement behaviour with the integrators. Include how product already on the steps or transfer rail is handled. The aim is a reviewable sequence rather than signal names without meaning. Safety functions and access conditions must be developed through the appropriate application assessment, separately from ordinary production demand logic.
Challenge the final release and reset boundary
Agree how the receiving tool confirms that a part has been taken and how a failed pickup is handled. Test the approved commissioning scenarios for an absent component, a double presentation and a stop between release and confirmation. Record what information is retained after reset so the system does not simply assume the transfer completed. Compare accepted presentations, recovery events and interventions for each approved component variant. These observations establish whether the complete feeding route supports the machine cycle under the declared production conditions.
