The leather applications

The leather applications
Leather cutting was formerly among the most demanding of manual tasks. The demands of the task have
remained, but the process has become almost fully automated. Fifteen years of progressive development
of leather cutting systems by the PARMEL team has bundled extensive application knowledge into an easily
manageable, high-performance application.
A modern production system, however, also includes features such as standardization of hardware and software, scalability, connectivity, a database, statistics and, last but not least, low operating costs.
All of this is offered by the RHINO leather cutting system.
One programme - a huge range of applications
The RHINO leather cutting system can be applied and configured for prototype-building, for small series and for mass
production in the automotive-, aircraft-, upholstery- and
related industries. In addition to full automation, the user
can if necessary determine freely and at any time the level of
interactive influence over the nesting/cutting results. RHINO
is also offered in software modules, e. g. for warehouse entry
and hide-inspection and for optimising roller die cutters.
Configurations
The system can be configured according to the following process steps: Job management, capture hide contour and quality
areas (1.), nesting the templates (2.), automatic cutting (3.)
and sorting (4.).
Configuration 1
The smallest configuration (prototyping) consists of a cutting table sized to take up one or more hides (depending on area). All
the process steps mentioned above are carried out in sequence.
The individual process times accumulate per cut/order.
Configuration 2
The increase in capacity is done by a conveyorised table extension in order to enlarge the work surface at the infeed of
the cutters by one segment. This allows the processes of hide
capture, nesting and cutting to be run in parallel. Capacity thus
increases by approx. 180 percent.
Configuration 3
Configuration 2 is extended by another conveyorised table
segment in the area of discharge (sorting). Processes 1.- 4. can
thus run in parallel and simultaneously. This helps you achieve a
nearly 300% performance boost over the single-table solution.

The processes
1. Hide capture
The hide laid out on the table is scanned with a high resolution camera. This captures the hide contours, the hide structure
(natural characteristics, holes, grain) and all indicated quality
symbols for the definition of usable areas (4 Q-zones). Along
with the evaluation of the hide illustration, the system stores all
the relevant hide parameters in the integrated data base.

2. Nesting process
The database-supported job management delivers the amount
of templates for automatic nesting onto the current hide. The
process time of the automatic nesting can be controlled automatically, depending on the cutting time. With particularly
sensitive products, the user can either nest via option "beamer
nesting" (with multi-function mouse) or place selected cut parts
on the screen and then leave optimisation of the remaining
usable area to the automatic function.

3. Cutting
In the three-table segment configured for high capacities,
there are constantly three hides in the overall process (capture, cut, sort), of which one is always cut. Minus the short
conveying times, the cutter, as the pacesetter of the system,
with a capacity utilisation of over 90 percent, ensures virtually
non-stop production.
4. Sorting of the finished cuts
As soon as the cutter has conveyed the contents of its cutting
window to the third table segment, the sorting process can
begin. The RHINO system offers a beamer-supported sorting
aid as an option.
5. Option for roller die cutters
The system combines the processes of hide detection and
automatic nesting with the punching process. Through it, the
final, optimised cutting image (marker) is projected by a highintensity beamer onto the hide and the punch dies are accordingly placed.
