Comau + Formificio Enzo (case005)
By implementing Comau’s articulated NS-12 robot as part of the Last Printing System project, Formificio Enzo can achieve high processing quality, model positioning repeatability and a correct orientation of the reference points to be marked.
The same size lasts that are printed with the new LPS (Last Printing System) using Comau NS-12 articulated robot are all identical, both in terms of both geometry and coordinates with respect to a Cartesian or Polar system. Because the paper patterns that are indelibly imprinted on a series of lasts have the same coordinates and orientation, they act as a solid and precise reference for the shoemaker. Naturally, such precision is guaranteed by the robot, which positions the last on the focal plane of the laser source. “Our production can be divided into two distinct departments, the first of which is dedicated to the creation of wooden models and prototypes, whereas the second deals with the mass productions of HDPE lasts,” explains. “In the modelling department, the development of prototypes can benefit from the expertise and experience of our master designers who, in turn, make use of the most advanced information technologies (CAD, CAM, ICT and structured light optical scanning systems) in order to turn a stylist’s ideas – even simple sketches – into unique models.”
Available and different evolution
The LPS is a complex system that uses a laser source to indelibly mark a polyethylene last with the purpose of engraving basic information on it, such as demographic, technical and metrological data required by the footwear industry.
Comau’s articulated NS-12 robot operates within a working area fenced by shielded walls and safety guards. Its task is to take the last from one of the twelve loading slots and place it beneath the laser source, in the different positions necessary for the marking. When the operation is complete, it sends a signal that activates the laser, which in turn creates the label.
As soon as it finishes its work, the NS-12 repositions itself to mark another label, until the list of locations for that particular last is exhausted.
