SECTION 18
GLOSSARY OF TERMS
This
term refers to the (optional) selection (on Screen 4) of alternate numbers of primary units
which are to be combined within a secondary case, with all units being arranged
in the same orientation.
See
Collation (below).
Case
The
final unit which is to be palletised. This may be defined by the user (in Palletise
mode) or may be constructed from primary / sub-primary units.
Case
Constraints.
When
a secondary case has been sized by the Collation module the external dimensions
will be compared with constraints that will exclude unsuitable cases from the
results.
Constraints
are specified by you for each packaging style on the Packaging Style screen
(Selected from Screen 3) and they can be
changed by amending the details shown.
Case
Sizing.
The external dimensions of a CASE are calculated for a collation of PRIMARY UNITS as follows:
Base:
the collation base dimension
+
material thickness x No. of thicknesses
+
total of gaps between each PRIMARY UNIT
+
constraint gap allowance
Height:
the collation height dimension
+
material thickness x No. of thicknesses
The
result is rounded up to the nearest millimetre on certain reports.
Collation
The
arrangement of primary units within a secondary case with all the units oriented
in the same direction. The number of primary unit tiers within the case is
governed by the stability constraint and by any restriction imposed by the user
on the number of tiers which can be used. This value is specified in the packing
style screen. Each tier will be identical to the first. A
three dimensional diagram may be seen on the computer screen if required
and the collation for each case is printed on both the 'Summary of Results' and
the 'Palletisation Specification' reports.
Collation
Tiers.
The
number of layers of primary units within a secondary case.
PALLETMANAGER
will investigate every collation within the size, stability and number of tiers
constraints imposed by you on the packaging style specification.
When the FIXED VOLUME module is being used the number of alternative collations that will be examined can be further reduced by entering the maximum number of tiers that you will be prepared to consider.
Conveyor
Width and Radius.
When
generating secondary units for a given number of primary cases, details of the
conveyor to be used can be entered and held on the conveyor details standard
value file. A width of zero indicates that no conveyor is in use.
PALLETMANAGER
will not attempt to palletise a secondary unit which will not travel along the
conveyor or around its tightest curve without overhanging.
Elevations.
A
printer report available in PALLETISE and Collation modes which provides views
from all four sides of the pallet stack.
Excluded
Cases.
When
PALLETMANAGER has sized a case for a particular collation the external
dimensions are checked against the pack constraints for the selected style of
packaging.
Where any constraint is exceeded, this case will be excluded from
analysis.
Details of excluded cases can be viewed from Screen 5.
Flip
Over Image.
Intermediate
layers of cases are a flip-over image of the first layer (in an axis
parallel to the pallet length), to provide interlocking.
Grid
Packing.
This
term is used to represent a packing in which the items packed (e.g. Cylinders)
form distinct rows and columns within the collation. (See Nesting)
Height/Base
Stability Ratio.
This
is a pack constraint that will exclude any collation where the external height
dimension of the secondary case is greater than the smallest base dimension
multiplied by the value held in the packaging style record.
Horizontal.
An option on Screen 6, the two / three dimensional pallet layout display, allows the placement on the pallet to be adjusted horizontally (on the screen) so at to 'even out' any gaps in a layout. A similar option to move vertically (on the screen) can also be selected. The effect of any movements applied can be removed by reselecting the appropriate layout number
JPG files.
A common graphics format used when displaying images on an Intranet / Internet. Can be viewed using a web browser such as explorer. Also used in the display of a company Logo on reports (see Appendix 1) or for display of product images in Collation mode (Section 6)
Layout.
An arrangement of a single layer of cases on a pallet or within a tray..
PALLETMANAGER
uses a variety of techniques to develop pallet loading patterns which make the
maximum use of the pallet loading area. The number of layouts which provide this
maximum utilisation will depend upon the shape and size of the case base and on
the load area of the pallet.
Sometimes there will be only one possible layout but at other times there
may be hundreds (usually if the case base is nearly square).
The
choice of an acceptable layout depends upon your own requirements, and the range
offered by PALLETMANAGER will meet most needs.
Mirror
Image.
Intermediate
layers of cases are a mirror image (in an axis parallel to the pallet width) of
the first layer to provide interlocking.
Mixed
Layer Mode
When
selected allows for the inter-mixing of layers of different types on the
pallet. See Section 11.
Nesting.
An
arrangement of cylinders in which adjacent items do NOT form distinct rows and
columns. A detailed description of the types of nesting pattern is given in Section
10.
Overhang - Actual
Layouts
are centralised on the pallet so that the actual overhang on a particular edge
will be half of the calculated total displayed on the Layout Screen (Screen 6).
Overhang
-
Long Side.
This entry (on Screen 3) is the TOTAL amount by which the load area length considered by PALLETMANAGER exceeds the larger pallet dimension.
Overhang
-
Short Side.
Is
the TOTAL amount by which the load area width considered by PALLETMANAGER
exceeds the shorter pallet dimension. In either case a negative sign indicates
dimension(s) less than the stated pallet length and/or width.
Overhang
Maximum.
The
maximum amount by which a case layout can be allowed to exceed a pallet edge
dimension.
As layouts are centralised the maximum should be twice the amount allowed
for one edge.
Packaging
Material Area.
The
area of packaging material in square metres is calculated according to the
equations given in Section 4 of this manual.
Palletisation
Specification.
The
printout produced at the end of your PALLETMANAGER investigation which can be
used as all or part of the specification issued as an instruction to the loading
department.
PDF Format.
A format devised by Adobe Systems for holding and displaying textual and graphics material.
Percentage
Fill.
The
'Summary of Results' report shows the percentage of load area and pallet volume
filled by the secondary case.
The total area and volume of the pallet (including maximum allowable
overhang) is used for this calculation.
Primary
Unit.
Any
cuboid or cylindrical shaped item that has to be packed into a secondary case.
Cylindrical
shapes must be expressed in three dimensions and the system will assume that
these units are cuboid.
"Nesting" of cylindrical units is also catered for.
The primary units must be identical.
Same.
This
option, displayed on Screen 6, the two and three dimensional layout display,
allows the user to select a stack made up of identical layers. Secondary
Unit.
The
outer case sized by the Collation module or an existing case that you wish to
palletise.
Sub-Primary
The
term used in Tertiary mode for the smallest individual unit. These are collated
to form primary units, then collated again to form the final case.
Tertiary
Mode
The
two stage collation of sub-primary units to form a case. Sub-primaries are
firstly collated to form a primary, and then collated once again to form the
case.
Ti-High
Refers to the number of boxes or cartons stored on a layer / tier (Ti) and the number of layers high these can be stacked in the pallet (Hi)
Top-Layer
Option.
When
selected, this permits the top layer of the pallet may consist of cases placed
on their side.
Tray or Tote.
Aside from the use of this term for designs of cardboard trays used to hold product, these terms are used for units (such as those popular in major stores) used to hold product in stackable re-usable units.
Underhang
(actual).
Layouts
are centralised on the pallet so that the amount by which the layout is inside
the pallet edge will be half of the calculated total displayed on Layout Screen
6. Underhang is shown as a negative value.
Underhang
(minimum)
The
minimum by which a pallet layout can be allowed to sit inside a pallet edge. As
layouts are centralised the minimum should be twice the amount allowed for one
edge.
Webbase.
A recently introduced feature whereby palletisation specifications may be made available for viewing by others on an Intranet / Internet or CD, with access being via their web browser.
