1. Brief description

A depacker separates the transport unit at the outlets into a defined number of products at the outlets.

2. Procedure and control description

The depacker can be used as a universal element for separating objects in an incoming product flow. In contrast to degrouping, the depacker can also be used to describe the packaging material, for example.

The depacker element has 1 input for the incoming product flow (e.g. full pallet with containers) and 2 outputs for the separated products and materials (e.g. packaging material).

This allows various machine functions or material flows to be simulated.

Some examples:

•Depalletizer (e.g. separation of bottles from a pallet)

•Crate unpacker (e.g. returnable bottle system)

•Unloading of filled carriers/shuttles (e.g. product carrier system)

The depacker can also be used to map shuttle or carrier systems with the modeling of a shuttle or carrier circuit.

After processing or transporting the products in the shuttle or on the carrier, the unit can be broken down into its individual objects again at the depacker (see also Packer element).

The separation (shares per product flow) of the objects (product or packaging material) can be defined via the two outputs of the depacker.

The operating speed (cycle time) and a failure behaviour (availability and MTTR) can be parameterized for the depacker. The operating speed refers to the material flow in the common area.

For the depacker, the input is the common area. If the quantity of processed material (e.g. product) is to be recorded at the element, the batch analysis must be activated for the evaluation.

It should be noted that the incoming units at the depacker are each counted as 1 object (e.g. pallet with bottles).

Figure 1 shows a variant for the Depacker.

Figure 3 - Depacker

Parameter	Required	Description
Name	x	Name of the element
Speed [pcs/min]	x	Working speed of the machine
Output 1 [pcs]	x	This number of products from a transport unit are separated at output 1
Output 2 [pcs]	x	This number of products from a transport unit are separated at output 2
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
