Container / Carton Indexing

Indexing systems that move each full carton, box, or tote out and the next empty one into place automatically, triggered by weight, by part count, or by a signal from the robot or press, so the press keeps running while the operator handles full containers.

LaRos over/under carton indexing system for robot filling

Application

Changing containers without stopping the press

Parts drop into the container at the fill position from your press, robot, or conveyor. When the container reaches its weight or count, or the robot or press signals for a new box, the system stops the feed, indexes the full container out, brings the next empty one into position, and restarts the feed. Each box filling and carton indexing system is built on our E-series conveyors and laid out to fit your containers and the floor space available.

System types

Indexing conveyor layouts

LaRos inline tote indexing conveyor with control panel

Inline (straight line)

Empty containers move into the fill position, and each full container indexes forward in a straight line to an accumulation section. The simplest layout, typically placed beside the molding press.

LaRos over/under carton indexing system

Over/under

Empty containers travel on one level and full containers on the other, which saves floor space. Also called an elevator system. Systems can lift full containers to overhead accumulation.

LaRos side-by-side tote indexing system

Side-by-side (90 and 180 degree)

Full containers turn off the fill line onto a take-away conveyor at 90 degrees, or return alongside it at 180 degrees. Suited to layouts where an inline system is too long for the space.

LaRos carousel box indexing system

Carousel

A rotating table carries several boxes around a fixed fill point and indexes the next empty box into position. A compact layout for indexing by count, or by weight with a separate weigh hopper.

Custom layouts are built for the space available, combining straight, turn, and return sections. Tote indexing systems with repeatable positioning are available for robot filling. Full containers can accumulate on gravity roller conveyor.

Controls

Three ways to trigger an index

Weigh counting: a scale under the fill position weighs the container and indexes it at the target weight, or at a part count calculated from weight.

Part counting: the control counts parts or machine cycles and indexes the container at the set count.

Signal from the robot or molding machine: the robot or press tells the system when to shift to a new box.

  • PLC control with index and reset buttons
  • Feed conveyor stops during indexing
  • Audible and visual alarms for "no empty container" and "take-away full"
  • SMART-VEYOR reject control interface
  • Controls for every layout, including over/under systems
