Delta Robots at the Case Packer Infeed: How Cermex RoboSELEX Collates Without Accumulation

Cermex RoboSELEX is Sidel’s robotic bottle-collating infeed for a case packer. It groups bottles for the packing operation; it is not the complete case packer. The buying question is whether a proposed bottle, grouping and downstream machine can work together under the required production conditions.

This guide interprets manufacturer information checked on October 16, 2026. It does not establish achieved line output, product-damage rates or installation results.

How the infeed forms groups

According to Sidel’s product page, two Delta robots position and reposition comb tooling while upstream conveyor-speed variation establishes bottle spacing. The described process groups bottles in continuous motion without accumulation. Sidel also describes shaped comb pockets and vision-based batch checking.

Our integration interpretation is that incoming presentation becomes a key trial condition. Ask how the proposed system responds to uneven spacing, a missing bottle, a rejected group and a downstream packing stop. “Without accumulation” describes this grouping process; it does not establish that every conveyor elsewhere in the line can dispense with buffering.

What the public specifications establish

The following are manufacturer-published values, not results measured by VMA:

Item	Sidel product-page statement	Qualification to resolve
Speed range	80–320 bottles/minute	Obtain a commitment for each bottle and grouping.
Grouping range	3 × 1 to 8 × 6 products, depending on product size	Confirm the permitted combinations for actual samples.
Same bottle, different grouping	1 minute	Define the start and finish conditions of the change.
Different bottle	2 minutes 30 seconds	Reconcile this with the press release before acceptance.

Bottle rate cannot be read directly as filled cases per minute. Request the complete packer cycle, group transfer arrangement, case presentation and treatment of rejected or incomplete groups. Keep the infeed’s capability separate from the accepted output of the assembled line.

Puck removal has a specific boundary

Sidel describes possible puck elimination for shaped bottles that can be conveyed but cannot be accumulated. This is conditional, not approval to remove carriers from every unstable bottle application.

For a sample trial, identify the filled bottle, cap, label, base geometry and upstream presentation. Ask the supplier to document whether the bottle can reach the grouping section consistently without its carrier, and what presentation the case packer requires at the handoff. Include the least favorable production samples and the restart after a normal downstream interruption. Have the supplier explain how failed presentations are detected and recovered.

Those are proposed evaluation questions. The public description does not establish that your bottle will pass them, or that an existing carrier can be removed without other line changes.

Keep the announcement dates and changeover claims distinct

On March 10, 2026, Sidel announced a planned RoboSELEX premiere with live demonstrations at Interpack, scheduled for May 7–13 in Düsseldorf. That release describes food, home-care and personal-care applications and gives approximately two minutes for changing bottle format. The product page instead lists two minutes thirty seconds.

The sources do not explain this difference. Request the applicable machine revision, tooling scope and changeover procedure rather than averaging the figures. Agree whether timing includes line clearance, guide adjustment, tool replacement, recipe selection, trial bottles and the first accepted case.

Packaging Europe’s report is dated September 11, 2026. That is a later reporting date, not the original announcement date. The March release establishes what Sidel planned to show; it does not by itself document the demonstration’s outcome. Likewise, Sidel’s broader beverage portfolio does not establish RoboSELEX suitability for a specific beverage line.

Questions for an integration proposal

Use the same bottle list and production requirements for every proposed configuration:

Interface	Evidence to request
Bottle handling	Sample coverage, permitted presentation variation and accepted surface damage limits
Existing packer	Mechanical transfer drawing, controls interface and responsibility for any retrofit
Format change	Included tooling, stored recipes, operator actions and timed acceptance method
Line interruption	Stop, reject, clear-out and restart sequence across both machines
Supply and support	Current price, included scope, US delivery date and local service arrangements

The cited Sidel pages do not provide a project price, US delivery commitment or independently measured customer OEE. Nor do they prove retrofit compatibility with an arbitrary existing packer. Confirm those items with Sidel for the offered configuration.

Define the process boundary using the case-packing guide, then carry the agreed handoff and recovery sequence into the packaging-line integration checklist.
