Abstract
An apparatus for cutting and/or marking products using laser beams includes at least one laser light emitter moveable in a first direction along a cross-bar, the cross-bar being in turn moveable above a working plane in a second direction transversal to the first direction, and at least two motors for moving the laser light emitter and the cross-bar. The laser light source is positioned to direct a laser light beam onto said working plane. Advantageously the two motors are positioned fixed and are coupled together and both to the laser light source, and to the cross-bar, by a transmission belt.

An apparatus for cutting and/or marking products by light beams, comprising a laser light source located in a fixed position to generate a laser light beam, reflection and focalizing optics including at least one laser light focalizing head to divert and focalize said laser light beam towards a working plane onto said products;
- said focalizing head being movable in a first direction (X) along a cross-bar, said cross-bar being in turn moveable above the working plane in a second direction (Y) transversal to said first direction (X), wherein the cross-bar engages two parallel guides arranged laterally with respect to said working plane, a single common transmission belt extends along an H path defined by the cross-bar and said two guides and engages said focalizing head and said cross-bar, to control its movement in said direction (Y), and to control the focalizing head movement in said direction (X), and said single transmission belt is driven by four motors, each of the four motors being positioned in correspondence of an end of said parallel guides, said single transmission belt connecting said four motors and being guided by idler wheels of the cross-bar.
A method for cutting and/or marking products positioned on a working plane by a laser beam, comprising the steps of providing a laser light focalizing head moveable above said working plane along two orthogonal directions, further comprising the step of moving said focalizing head using only a single transmission belt driven by four motors having fixed positions.
A method for cutting and/or marking products by laser light beams, comprising:
- positioning a laser light source in a fixed position to generate a laser light beam;
- providing reflection and focalizing optics including at least one laser light focalizing head to divert and focalize said laser light beam towards a working plane onto said products;
- configuring said focalizing head to be movable in a first direction (X) along a cross-bar, said cross-bar being in turn moveable above the working plane in a second direction (Y) transversal to said first direction (X);
- engaging two parallel guides arranged laterally with respect to said working plane with the cross-bar;
- providing a single transmission belt to extend along an H path defined by the cross-bar and said two guides to engage said focalizing head and said cross-bar, to control its movement in said direction (Y), and to control the focalizing head movement in said direction (X);
- and
- driving said single transmission belt by four motors, each of the four motors being positioned in correspondence of an end of said lateral guides, said single transmission belt connecting said four motors and being guided by idler wheels of the cross-bar.
