Custom-engineered
solutions for turnkey part marking
Dapra
Marking has been providing standard Dot Peen
Marking solutions since 1985. Now, Dapra
Marking has grown and can provide integrated
and turnkey direct part marking solutions
for both Dot Peen Marking and Diode-Pumped
Laser Marking applications.
We
have the capability to design and build custom-engineered
solutions to specifically meet your needs.
Whether your turnkey project is small or
large, Dapra can review your requirements
and provide your company with a quotation
and specifications that are price-competitive.
The one thing you can count on is that, as
always, Dapra will provide a quality solution.
The
key to our custom-engineered solutions is
the combination of fixturing and material
handling with either a Dot Peen or Laser
Marking System. This integration of technologies
ensures that the part is secured and that
production rate and marking requirements
are met. In many cases, we can integrate
vision systems for part orientation or to
read and verify Data Matrix codes required
in the Aerospace (SPEC2000) and Automotive
industries.
 |
In
addition to custom-engineered hardware,
Dapra offers a wide variety of standard
and modified accessories. These include
rotary devices for marking round parts;
scribe or drag attachments for solid
line marking; deep marking attachments;
multiple solenoids; Autosense for automatically
detecting the marking surface; and
tag/label feeding attachments for marking
on blank or preformatted tags.
Dapra
can even provide custom software,
such as a special Graphics User Interface
(GUI), for use at the operator level
or a program to enable communication
with your database to download specific
information into the marking layout.
Remember:
Dapra Marking is more than just standard
marking systems; we are TURNKEY MARKING
SOLUTIONS!

the Integrator CEG is light in
weight, it may be easily mounted
onto a robotic arm. An optional
column and base enable conversion

Dapra
Marking's newest product is our Compact
Integrator CEG Dot Peen Marking System. Based on the
proven technology of the 2068
family of Dot Peen Marking Systems, the
Integrator CEG offers new parameters for
integrating marking and production machinery.
The Integrator CEG allows for simple installation
into new machine and design applications,
as well as retrofitting into existing production
lines where space is at a premium.
The
Integrator CEG offers all the programming
features associated with the 2068 series,
plus the ability to mount on multiple faces
and to change the cable entry orientation.
The 2" x 1" marking window allows
for multiple lines of data to be marked,
and the RS-232 serial and digital I/O ports
enable simple interfacing to download data
and for external cycle start/stop applications.
The
compact, ergonomic controller for the CEG
incorporates user-friendly embedded marking
software to program quick setups for different
character sizes, fonts and marking forces,
as well as incremental serialization and
date coding. The controller design is easily
adapted to the production floor, since a
PC is not required for operation.
If
required, the CEG can be configured to mark
Data Matrix codes directly onto the work
piece for improved traceability.
If
your requirements are for a turnkey or complete
integrated marking project, Dapra Marking
can design and build to your specifications,
including software modifications streamlined
to your traceability needs.

What type of serial communications are
available?
The 2068 Series II controller
has (2) RS-232 serial ports (A and B) that can
be used for many purposes. The older 2068 controller
has (1) RS-232 serial port. Each system can be
configured for function, baud rate, data bits
and parity.
Can
I use the RS-232 for barcoding data into the
marking system?
A barcode scanner connected to
the RS-232 can scan information from routers, work
orders or other barcoded documentation, directly
into the current layout. More than one line in
a layout may be configured to receive barcoded
data. This is a very useful tool in eliminating
data input errors associated with manual operations.
Can
I use the RS-232 to input data from another
computer or serial device?
The standard "Select Layout" mode
allows an external device to perform the following
operations via the RS-232:
| • |
Select
any layout from any group. |
| • |
Replace
any variables in the current layout with
new data. |
| • |
Mark
the current layout. |
Select
layout is a powerful mode and can be used in
a wide variety of situations.
Can
I send "batches" of information to
be marked using the RS-232?
Batch mode allows a remote device to send a batch
of data to the controller. Each item specifies a layout name and
the contents of any variables in that layout. The items are held
in a first-in, first-out queue that can hold up to 64,000 characters.
Items can be added to the queue without overwriting previous items.
The queue contents are maintained even when the power is switched
off.
Can
I send marking information out of the serial
port to a remote device?
The serial output mode allows data to be transmitted
from the serial port at any point within a marking layout. This
mode is useful when interfacing to serial printers and similar
devices.

Class 1 Laser Marking Enclosure Facilitates
Marking Around the Diameter of Components |
Dapra
Marking now offers an additional enclosure
for Class 1 Laser Marking applications.
This design can be used to retrofit
the original-style 5W, 10W or 20W diode-pumped
laser. The new design allows the use
of programmable Z-axis and rotary marking
capabilities for marking around the
diameter of components.

A
robust, lightweight design allows the HandHeld
to be used in a wide range of manufacturing
environments. A high-resolution LCD screen
enables the user to easily view the information
to be marked. A simple interface means integration
into already-established workflows is quick
and simple. |
The
ability to control illegible marks is now at their
fingertips
In
2002, a domestic steel manufacturer began to investigate
the feasibility of installing portable marking
units in its shear, flame cut and heat treat test
areas. These units would replace the hand-stamping
of test coupons. Due to the location and setup
of the shear area, as well as the volume of test
coupons that pass through, it was determined that
this portion of their manufacturing process would
serve as the beta location to test the installation
of a new marking system. The goal for this project
was to provide a portable, cost-effective, low-maintenance
system that would improve the quality of their
marks, eliminate errors and be user-friendly.
Many
marking units were evaluated for portability, maintenance,
durability, ease of setup and, most importantly,
stamping quality. Operators were involved in the
evaluation testing from the beginning and they
quickly eliminated all units requiring air. The
operators felt that the quality of air needed to
power pneumatic systems, as well as the potential
difficulties with "winter freeze," would
create unnecessary problems. From the remaining
electromagnetic systems, the Dapra Marking HandHeld
unit was selected.
Once
the HandHeld unit (consisting of a controller
with keyboard, portable marking unit and
barcode reader for
data input) was delivered, a variety of setups were tested. Various
customizable settings, including speed, font size, marking force
and direction, were adjusted to optimize the readability of the
marks. Many samples were reviewed by the operations and plate technology
staff and the chosen sample's settings were programmed. Custom
software was developed to display the data scanned into the marking
system from the barcode reader — this preview allowed the
test operators to verify data prior to marking.
The
steel manufacturer was extremely pleased
with the reliability of Dapra Marking's
HandHeld unit — they are
now in the process of purchasing additional systems for integration
into other areas of operation. The positive feedback from the operators,
combined with the HandHeld's ease of use and ability to easily
interface with their original setup, has made it a success.
