APPARATUS AND METHOD FOR PRINTING LABELS
The present invention relates to apparatus for and a method of
printing labels, and particularly but not exclusively apparatus for and a
method of printing labels which are compatible with a computer system
running a Computer Aided Design CAD.
Typically systems or networks are designed with CAD software
before they are installed. The various components to be installed such as
PCs and cables , in the case where a computer network is to be installed,
are tested and then labelled. This aids those installing the system or
network and allows those who may have to upgrade the network in future
years to easily identify components and cables which need to be replaced.
Typically a list of component and cable identification numbers are
generated during the design. The identification numbers are then manually
input to a computer and corresponding labels are created. The labels may
then be attached to the desired components. This process is time
consuming and leaves much opportunity for human error.
It is therefore an object of the present invention to provide
apparatus for and a method of printing appropriate identification labels
which is less error prone and less time consuming.
According to a first aspect of the present invention there is
provided an apparatus for producing a label comprising a monitor for
displaying a diagram comprising one or more components, means for
selecting a component on the diagram, a database for storing information
relating to the or each component, means for retrieving information from
the database relating to the selected component and for introducing the
retrieved information into a label template and means for printing out a
label containing the label template and retrieved information.
According to a second aspect of the present invention there is
provided a method of producing a label including the steps of displaying a
diagram comprising one or more components on a monitor, selecting a
component on the diagram, retrieving stored information relating to the
component from a database, introducing the retrieved information into a
label template and printing a label containing the label template and the
retrieved information.
Preferably the monitor for displaying a diagram is part of a
computer system. Most preferably the computer system additionally
incorporates a printing means and at least one of a keyboard and a
pointing device which may be a mouse, trackerball, joystick, data tracker,
digitiser light pen or similar.
Preferably the means for displaying the diagram upon the monitor is
a computer aided design (CAD) software. In a preferred embodiment the
CAD software used is Microsoft (Registered Trade Mark) Visio (Registered
Trade Mark). In an alternative embodiment the preferred CAD software is
Autocad (Registered Trade Mark).
Preferably the diagram is representative of a design for a system or
network. Such systems or networks may be a computer network, an
electrical power distribution circuit, a telecommunications network, a
heating and/or air-conditioning system or any similar network or system.
Preferably each component in the diagram is represented by an
icon, which is an object of the CAD software. Most preferably, each
icon, in addition to the standard properties of an object of the CAD
software has additional properties, preferably the additional properties are
a label template and an identification number. In a particularly preferred
embodiment the identification number is displayed adjacent to or partially
over the icon it refers to when the icon is displayed on the monitor.
Preferably a database corresponding to the diagram is created at
substantially the same time as the diagram is created, the database
containing information relating to the or each component in the diagram.
The information stored in the database preferably includes the
identification number and at least some of component description,
component serial number component closet number and component
location.
Preferably as the icons are objects a user may make an exact copy
of a selected component, system or subsystem by issuing a copy command in the CAD software. Preferably a user may also create and
store a stencil of a selected component, system or subsystem.
Preferably components which are similar or identical will be
represented by identical icons in the diagram. Most preferably identical
icons have identical label templates.
Preferably a component is selected by using the pointing device or
the keyboard to select the appropriate icon. If a label to identify the
selected component is to be printed a print command can be issued using
the pointing device or the keyboard.
The print command may be issued by double clicking on the icon
with the pointing device, by pressing a particular combination of keys on
the keyboard or by selecting a print command from an appropriate menu.
Preferably when a print command has been issued the database
record relating to the selected components identification number is
retrieved and the information in the database record is merged with the
label template associated with the components icon. Most preferably the
merged label template and database information are then routed to the
printing means which prints a label containing the retrieved information
and the label template.
The printing means may be either a desktop printer or a specialised
label printer as desired.
In order that the present invention may be more clearly understood,
one embodiment thereof will now be described further, by way of
example only and with reference to the following drawings, in which:-
Figure 1 is a block diagram of a typical computer system which might
be used to carry out the invention.
Figure 2 is a block diagram of a simple computer network which may
be provided with appropriate labels using the present invention.
The particular embodiment of the present invention described herein
is carried out by a computer system 2 provided with suitably adapted
computer aided design (CAD) software. Examples of suitable CAD
software packages are Microsoft (Registered Trade Mark) Visio
(Registered Trade Mark), Autocad (Registered Trade Mark) or other similar
packages.
Referring to figure 1 the computer system 2 comprises a main body
4, which incorporates processing and memory means, a monitor 6 or
other suitable display unit, a keyboard 1 0, mouse 1 2 or other suitable
pointing device and printing means 8 which may be a standard desktop
printer or a dedicated label printer.
Figure 2 shows a block diagram of a simple network which may be
designed and installed with the help of the present invention. It
comprises personal computers 14-20, printers 22 and 24, all connected
to a server 26 by cables 104-1 14.
Whilst the particular example shown in figure 2 is a computer
network the invention is applicable to other engineering systems or
networks, a non-exhaustive list of which may include electrical power
distribution circuitry, telecommunications networks, heating and/or air-
conditional systems
When designing a network using the CAD software installed on
computer system 2 the computers 14-20, the printers 22, 24 and the
server 26 will be represented by appropriate icons. Each icon includes an
identification number 1 4a-26a. The connecting cables 104-1 14 will
typically be represented by lines each incorporating an identification
number 104a-1 14a.
A user of the invention will design the network in a conventional
manner and generate identification numbers in the normal manner. A
database of the components will also be created by the user. The records
in the database will include the identification numbers and other relevant
information about the various cable and components of the network.
Typical examples of information to be stored includes identification
number, component description, component serial number, component
asset number and component location.
When a user wishes to print a label for a particular component or
cable they first select the appropriate icon for the component and then
issue a print command. This can be done directly by double clicking the
pointing device 1 2 or by using a keyboard shortcut 10. On issuance of a
print command labelling information relating to the component selected is
retrieved and automatically merged with a label template and the merged
information and template routed to the printer to print the label.
Alternatively, in a modification, on selection the user is provided
with a menu from which a printer command can be chosen. The choice
may include the conventional cut, copy and paste commands as well as
commands for printing a diagram for the whole system, the selected
subsystem or the selected component or simply a label for the whole
system, the selected subsystem or the selected component.
Each icon displayed on screen is an object of the CAD software.
Each icon has in the present invention, in addition to their standard
properties two extra properties an identification number which is the
same as the identification number displayed 14a-26a, 104a- 1 1 6a on the
icons.
The computer system 2 uses the identification number of the icon
to search the database for the record corresponding to the selected icon.
The information contained in the database record is then retrieved and
merged with the label template associated with the icon. The merged
label template and database information are then routed to the printing
means 8 and a label of the desired form is printed.
The label solution is object oriented and allows the user to make a
copy of a component, system or sub-system solution by simply selecting
copy in the CAD workspace. This is an exact copy and all information in
the fields for the label will be the same as the original and would have to
be edited. However, a copy can be made and stored as a stencil and the
fields apart from the correct label template will be blank for the user to fill
in. The stored stencils form a library of label solutions.
In normal operation icons which have the same image, i.e. icons
which represent similar components will have a common label template.
This is because components which are identical or similar will need to
have similar information printed on their identification labels.
Laminated tapes consisting of six layers of materials, provide a thin,
yet extremely strong label. Characters formed with thermal transfer ink
are actually printed onto the underside of the laminate, sandwiched
between two layers of PET ( polyester film) creating characters that are
virtually indestructible. Tests have shown that the tapes can withstand
temperatures from -50 and up to 21 2 degrees Celsius. It has been
proven that the tapes withstand heavy abrasion, are electrically resistant
and withstand lengthy exposure to both chemicals and water.
In certain circumstances, for instance labelling cables, non-
laminated flexible tape provides a letter labelling solution. Such tape is
typically backed with adhesive and attached either along the length of the
cable or around the circumference of the cable to form a flag.
It should be understood that the term label includes not only a
separate item attached to the component in question, but also a stamp attached to the component, for example with an adhesive, or the direct
printing of the information on the component.
It is of course to be understood that the above detailed embodiment
is described by way of example only and that many variations are possible without departing from the invention.
