1. Brief description

A packer combines a defined number of products from 2 inputs at the input and passes them on as a transport unit.

2. Procedure and control description

The packer can be used as a universal element for merging two product streams. In contrast to grouping, the packer can also be used to describe the packaging material, for example.

The packer element has 2 inputs for incoming product streams (e.g. for containers and packaging material) and one output for the combined transport unit.

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

Some examples:

•Filling quantity of product per container (e.g. bottle filling)

•Number of labels per product (e.g. labeling machine)

•Number of products per carton (case packer)

•Number of cartons per pallet (palletizer)

It should be noted that the unit dispensed by the packer consists of the number of grouped input products, but is counted as 1 object.

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

After the products have been processed or transported in the shuttle or on the carrier, the unit can be dissolved again later (see also unpacker element).

The composition (proportions per product flow) of the transport unit (product) to be assembled can be defined via the two inputs of the packer.

The operating speed (cycle time) and a failure behaviour (availability and MTTR) can be parameterized for the packer. The operating speed refers to the area in which the two product streams are brought together.

In the case of the packer, this is the outfeed of the element. The packer always “waits” for the other product/material flow. If the material flow is interrupted at an input of the element, i.e. no product is present, the packer stops.

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.

Figure 1 shows different variants of the packer.

	Element packer as a filling machine (e.g. 0.5/1 bottle)
	Element packer as a capper (1 cap/1 bottle)
	Element packer as a labeler (1 label/1 bottle)
	Element packer as a case packer (10 bottles/1 carton)

Figure 3 - Packer

Parameter	Required	Description
Name	x	Name of the element
Speed [pcs/min]	x	Working speed of the machine
Product from Input	x	Enter the input from which the product is delivered
Input 1 [pcs]	x	This number of products from input 1 are combined with the products from input 2 to form a transport unit
Input 2 [pcs]	x	This number of products from input 2 are combined with the products from input 1 to form a transport unit
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
