1. Brief description

Degrouping separates/splits products grouped together in transport units into individual products.

2. Procedure and control description

The degrouping element can be used to describe a degrouping behavior (separation of a unit). The element separates / breaks down products combined into transport units (e.g. by grouping or packing) into individual products.

This allows material groups (product) to be broken down for further processing. (e.g. x bottles on a depalletizer).

It should be noted that the number of units dispensed from the de-grouping (from one incoming grouped unit in each case) is determined exclusively by the parameterization in the element and not by any upstream grouping or packaging process.

A grouping behaves like an depacker (see Depacker element), but without a description of the packaging material. Degrouping can also be used to map shuttle or carrier systems without having to model a shuttle or carrier cycle.

An incoming filled shuttle or an incoming carrier can be broken down into the number of products loaded. The working speed (cycle time) and a failure behaviour (availability and MTTR) can be parameterized for the grouping;

the failure behaviour is deactivated in the default setting. If the quantity of processed material (e.g. product) is to be recorded on the element, the batch analysis must be activated for the evaluation.

Figure 1 shows a depalletizer as a degrouping without pallet removal (packaging aids). The units dispensed consist of a 500 bottles per pallet.

Parameter	Required	Description
Name	x	Name of the element
Speed [pcs/min]	x	Working speed of the machine
Split input value in [pcs]	x	a transport unit is separated into this number of products
Own fault active	x	Activate/deactivate failure
Reliability [%]	x	Percentage of time the process operates or functions without any disruption. Defects are randomly generated only during the work phase of the process on a unit/part.
MTTR - Distribution	x	Distribution function for MTTR
Mean [s]	x	The average time required to repair a machine at the time of failure. MTTR is generally calculated by adding the TTR (time to repair) of all failures divided by the total number of failures.
Batch analysis active	x	Activate/deactivate batch result display. Default: activated
