Installing a conveyor system at a business facility generally involves significant costs.
It can also be costly to change an existing conveyor system. With FlexSim, you can
experiment risk-free until you find the ideal way to configure your conveyor system and
maximize its throughput.
FlexSim's conveyor objects have several useful features:
Slug Building and Merge Control - You can create
conveyors that will accumulate a slug of items on a conveyor and then release it once
the slug is ready. Using this feature in conjunction with the merge controller object
and/or the Process Flow tool, you can easily implement sawtooth merges without writing
any custom code.
Range-Based Transfer Points - Operators can pick up
or drop off items from a range of possible transfer points along the conveyor rather
than a single fixed point, making it easier to simulate picking operations. When picking
items from a conveyor, operators will automatically predict a proper pick up point on
the conveyor based on item speed, operator speed, and distance.
Improved Photo Eyes - You can build more
sophisticated logic into photo eyes, such as programming them to trigger certain events
or logic if they are blocked or if they are clear for a specific amount of time. You can
also make more precise adjustments to the height and angle of the photo eye on the
Decision Points and Stations - Decision points and
stations can be used to build complex logic into a conveyor system. You can place
decision point objects and stations on a conveyor to act as a sensor, processing
station, or a communication point for other objects, such as the merge controller.
Improved Movement Controls - FlexSim's conveyor
system has many possible options for controlling how items transfer between the
conveyors, including speed, delay time, and pop-up distance. You can also adjust a
roller skew angle on a conveyor, so that items will accumulate on one side of the
conveyor if needed. You can also tilt, translate, and rotate items while moving along
Item Orientation - You can define any orientation
for items on a conveyor. This orientation will automatically persist across multiple
sections, and will update its calculations to match the object's orientation when the
item transfers through side transfers.
Power and Free - With the conveyor system you can
simulate power and free systems and easily define the chain's dog gap.
Controlling Logic and Properties With Global Types
If you're already used to working with 3D objects in FlexSim, there will be a few things
about working with conveyor objects that are a little different from standard 3D objects.
Some of these differences are discussed in the
Working With Conveyors
However, one key difference is that conveyor objects can have global types,
which make it easy to quickly update custom properties and logic on several conveyor objects
In order to understand how global types work, it's helpful to define a few key terms as
they apply in this context:
Properties - Settings that affect the visuals or
the basic functionality of a conveyor object, such as its position in the 3D model, its
size, its color, and other similar settings.
Logic - Settings that affect a conveyor object's
behavior, including how it interacts with other objects and flow items. NOTE: Usually
logic is also controlled by an object's properties, but this topic is making a slight
distinction for clarity when working with conveyor objects.
Local - If a conveyor object's properties/logic are
local, that means those settings will only apply to that individual object. If you edit
local properties/logic, it will only change the settings for that one object and nothing
Global - A conveyor object's properties/logic can
be globally accessible, making it possible to assign a custom set of properties or logic
to multiple objects at the same time. Then, when you edit those global settings, it
changes the settings for all those objects simultaneously.
Each kind of conveyor object has unique properties and logic. For the most part, you can
create one or more global types for each conveyor object. When you're working with conveyor
objects, consider whether it would be more advantageous to apply properties/logic locally to
a single object or whether it would be more effective to create a global type that you can
quickly apply those settings to multiple objects simultaneously.
In general, the process for using conveyor object types is as follows:
Create a Global Type - Using the Toolbox, you'll
create a global type and set its logic or properties. You can create several different
global types if needed, even for the same kind of conveyor object.
Set a Conveyor's Type - In Properties, assign a conveyor object to one of the global types you
Edit the Conveyor Type - If you want to make a
global change that will affect the settings for all the conveyors of one type, you can
edit the conveyor type settings in the Toolbox. It will then immediately update the
default settings for all the conveyors at the same time.
See Using Global
Types for more specific instructions, including how to make a conveyor object's
settings change back to local.
Conveyor System Settings
The Conveyor System properties window can be used to set the default properties for all
conveyor objects in your simulation model. For example, you can create custom conveyor types
and then use the conveyor system tool to ensure that each new conveyor you create is
automatically assigned that type. You can also use the Conveyor System properties to change
the visual settings for the conveyor system. See
- Conveyor System for more information.
