Laser cutting debris collection system
10507546 · 2019-12-17 · ·

Apparatuses include a laser cutter positioned within an enclosure that is capable of cutting printed sheets; however, this cutting produces debris made up of airborne dust of the sheet material and marking material. An air duct is capable of drawing an air stream of air and the debris out of the enclosure. A dispenser is positioned within the air duct where the air duct connects to the enclosure. The dispenser is capable of dispensing a dry powder of calcium carbonate into the air stream. The dry powder attaches to the debris. The combination of the dry powder and the debris forms waste, and a filter device (that is connected to the air duct) filters the waste. The filter device is capable of separating the air from the waste, to collect the waste and release the air free of the waste to areas outside the filter device.

The present invention relates to an improved cutting device and an improved cutting method, specifically for processing and cutting sheets of stiff material, such as cardboard and others, in which the sheets are supplied and moved in a stable way along a first direction, and a laser cutting unit (or at least the resulting laser beams) is moved along a second, substantially perpendicular direction, in which by coordinating the two movements, a desired cut is executed in the sheets.

System and Method for Variable Perforation Profiles in a Stack of Lottery Tickets
20190332092 · 2019-10-31 ·

A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line. A perforation machine in the line is controlled to define a perforation line between the adjacent lottery tickets. The controlling process includes inputting control variables into a controller associated with the perforation machine, the control variables relating to conditions that determine a desired perforation profile of the perforation line. The controller programs the perforation machine with a specific perforation profile for the perforation line that is generated based on the entered control variables, and changes the perforation profile upon inputting of different values for the control variables. The perforation profile is specifically tailored to the control variables between different ticket production runs, or between tickets in the same ticket production run.

Weakening Device and Method for Weakening Packaging Materials
20190321919 · 2019-10-24 ·

Described is a weakening device for weakening packaging materials having at least one laser unit comprising a laser having a laser beam and at least one transport device for transport of the packaging material relative to the laser unit. The laser unit has at least one focusing optics for focusing the laser beam on the packaging material transported relative to the laser. In order to be able to inscribe both straight lines of weakness and shapes included from lines, it is provided that the laser unit has at least one scanner for adjusting the laser beam at least in one direction transversely to the transport direction for inscribing predetermined shapes into the packaging material transported past the laser, and that a beam switch is provided in the path of the laser beam for transmitting the beam to the focusing optics in a liner position or to the scanner.

A method for processing a cardboard (12) with a laser beam (14) is provided, wherein the laser beam (14) is moved over the cardboard (12) along a desired folding line (24) such that an upper layer of the cardboard (12) is ablated without cutting through the cardboard (12), wherein the laser beam (14) is adjusted such that the laser beam (14) is focused below the cardboard (12). Further, a device (10) for carrying out a method for processing a cardboard (12) with a laser beam (14) is provided.

METHOD FOR CURING SOLDER PASTE ON A THERMALLY FRAGILE SUBSTRATE
20190230796 · 2019-07-25 · ·

A method for curing solder paste on a thermally fragile substrate is disclosed. An optically reflective layer and an optically absorptive layer are printed on a thermally fragile substrate. Multiple conductive traces are selectively deposited on the optically reflective layer and on the optically absorptive layer. Solder paste is then applied on selective locations that are corresponding to locations of the optically absorptive layer. After a component has been placed on the solder paste, the substrate is irradiated from one side with uniform pulsed light. The optically absorptive layer absorbs the pulsed light and becomes heated, and the heat is subsequently transferred to the solder paste and the cornponent via thermal conduction in order to heat and melt the solder paste.

A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line prior to being folded into a Z-fold pattern for subsequent packaging. A perforation machine in the line is controlled by a controller for defining the perforation lines, wherein the control process includes determining the perforation lines that correspond to fold lines in the Z-fold pattern and, for these perforation lines, programming the perforation machine to generate a second perforation profile that is different from a first perforation profile of non-fold perforation lines that lie between the fold lines in the Z-fold pattern. The second perforation profile is specifically tailored to produce a stronger perforation line to compensate for weakness induced in the perforation line from being folded.
