PACKAGING & MATERIAL HANDLING / SERVO ELECTRIC CYLINDER STUDY

A carton transfer axis synchronized to the conveyor

Design the pusher around the product window, not an isolated actuator speed rating.

Conceptual conveyor carton-transfer axis with broad pusher face and external linear guides
THE OPERATING REQUIREMENT

What this axis must achieve.

Product / operation

Carton sorting and lane transfer

Engineering example

20 kg carton; 300 mm transfer travel

Motion example

0.6 m/s peak pusher velocity; 2 m/s² acceleration

Engineering feasibility study: assumed inputs and calculated values; conceptual equipment illustrations. Proposed checks require project approval and measured trials.

MECHANICAL DESIGN

Guide the pusher and protect the product window.

An externally guided pusher

The carriage carries offset moments, with clearance for skewed cartons. A broad contact face distributes the transfer force without loading the cylinder rod sideways.

A defined product window

Photoeyes confirm arrival and clearance. Relate sensing latency and conveyor speed to the available transfer window, with jam detection and a controlled reset.

SIZING WITH DECLARED ASSUMPTIONS

Travel comes from the complete speed profile.

At 0.6 m/s and 2 m/s², each ramp takes 0.3 s and covers 90 mm. The remaining 120 mm takes 0.2 s: 0.8 s outward, or 1.6 s ideal round trip. Detection, dwell and conveyor delays add time. Size the total moving carriage and payload together.

CONTROL AND RECOVERY

A controlled cycle has defined exit conditions.

Detect and authorize

Identify a qualified carton and confirm lane availability, carriage reference and line-ready conditions.

Track arrival

Use the line timing/encoder architecture to predict the transfer window and reject stale triggers.

Transfer

Execute the product-specific profile while monitoring permitted load, travel and time.

Verify and return

Confirm the transfer and retract before the next approved window.

Handle a jam

Stop the defined sequence, identify carton state and perform controlled clearance; prevent an automatic second hit on an unknown carton.

Check before resetting: Late transfer: Check trigger position, conveyor-speed reference, communication delay and the complete occupied time. Carton rotates or tips: Review contact height/area, acceleration, lane support and carton variability.

PROPOSED VERIFICATION

Verify the product window and carton clearance.

Target

Proposed transfer trial: 100 consecutive cartons at the agreed conveyor/product window, with zero missed transfer commands or carton damage. The 1.6 s calculation excludes sensing, dwell and conveyor delays; production throughput must be measured.

Method and record

Measure product detection-to-motion latency and carton arrival window at minimum/nominal/maximum conveyor speed. Verify clearance with the largest carton and worst permitted skew. Record actual outward/return times and motor temperature. Challenge missing carton, blocked guide and late arrival with an approved recovery sequence.

Record actual value, conditions, uncertainty, result and approval. Test status: planned; measured results remain to be recorded at FAT.

NEFEIT CONFIGURATION REVIEW

Specify the actuator and its interfaces.

The useful RFQ includes line speed, carton spacing, product dimensions, receiving-lane geometry and the full transfer/return window. It should also state who owns tracking logic and product-damage acceptance. That information avoids selecting an axis from thrust and stroke alone.

Confirm thrust versus speed, stroke, duty, mounting, motor/drive, feedback and environment together. The NFT40 photograph illustrates the product family; the study does not select that exact model.

Engineering pack: operating-cycle sizing, configuration and interface drawing, responsibility split, lubrication provisions and an agreed test plan.

APPLICATION QUESTIONS

Clarify the decision before quotation.

Acceleration, outbound and return stroke, dwell, sensing latency and product clearance all occupy the line window. The complete sequence must fit.

Only if the qualified size, mass, strength and timing envelope supports it. Different products often require bounded profiles and controlled recipe selection.

Request the configuration-specific sizing review, interface drawing, supply boundary and proposed acceptance plan. This feasibility study contains assumed inputs and calculated values; it does not report a delivered customer project or completed FAT.
