Controller output matched to the validated loaded-track condition.
Application engineering
Give the track a clear view of supply and demand.
Controls should keep useful accumulation inside a stable operating window and communicate predictable states to the upstream feeder and downstream machine.
Application inputPart · orientation · rate · interface
Sensors placed to represent demand, depletion and fault conditions.
Run, ready, demand, fault and reset behaviour agreed with the machine builder.
Control architecture
A / 01The right signal at the right point prevents unnecessary cycling.
A linear feeder may need a standalone controller, a local control panel or full coordination through the parent machine PLC. The appropriate boundary depends on project scope and who owns the overall risk assessment and sequence.
Sensor technology is selected around component material, colour, reflectivity, size, speed, environmental conditions and the required diagnostic confidence.
Sensor placement should describe a process state—not merely detect that a component happens to be present at one instant.
Typical states
Signals commonly considered in a linear feeding system.
01Downstream ready
Confirms the receiving process can accept another component or release cycle.
02Part at escapement
Confirms the expected presentation is available before the machine acts.
03Track low
Warns that the useful queue is approaching depletion.
04Track full
Reduces or stops upstream supply before harmful queue pressure develops.
05Demand
Requests replenishment from the bowl, step feeder, hopper or upstream process.
06Jam / no movement
Uses timing or expected state change to distinguish a normal pause from a blocked path.
07Fault / reset
Provides a deliberate recovery sequence rather than uncontrolled automatic restart.
Controller functions
Build the operating window around the complete loaded track.
Amplitude control
Set and lock a stable conveying condition with the production tooling and representative load fitted.
Soft start / stop
Reduce sudden surges or bounce where a controlled ramp improves component stability.
Demand control
Use queue state to slow or stop upstream supply and prevent overfilling.
Recipe handling
Where variants are validated, store settings with controlled access and clear changeover confirmation.
Integration brief
Agree ownership before panel design.
The functional description should identify which controller owns each motor, sensor, stop condition, alarm and reset. It should also define safe behaviour when communications or downstream-ready signals are lost.
- Supply voltage and electrical standard
- Preferred controls platform and network
- Dry-contact or fieldbus signal list
- Emergency-stop and guard-circuit boundary
- Fault classification and operator messages
- Manual, setup and automatic-mode permissions
Common questions
Linear feeder questions, answered.
Practical guidance for an early project review. Final design and performance are confirmed against the actual application.
01What sensors are used on linear feeders?+
Photoelectric, fibre-optic, inductive and other sensing methods may be considered. Selection depends on component size, material, colour, reflectivity, speed, available space and environmental conditions.
02How is a feeder jam detected?+
Jam detection is often based on an expected state change within a defined time, sometimes combined with upstream and downstream occupancy. A single blocked beam may represent a normal full queue, so the logic must match the process.
03Can the feeder connect to a PLC?+
Yes. Common interfaces include discrete signals and industrial communications, subject to the selected controls platform and agreed project scope.
