Abstract
An edible decoration is laser kiss cut from an edible decorating sheet by optically sensing at least one printed edible design on the edible decorating sheet relative to a laser cutting tool coordinate system and driving a laser along a circuit of cutting locations defined in the laser cutting tool coordinate system. The laser beam forms a separation channel by laser ablation of at least a portion of the edible decorating sheet at the cutting locations while leaving intact the non-adhesive releasable backing upon which the edible decorating sheet rests.
Claims18
A system for producing edible decorations from edible decorating sheets, the system comprising:
- at least one controller;
- a transport system for transporting an edible decorating sheet comprising one or more layers of edible material deposited on a backing substrate;
- and
- a laser cutting tool positioned along the transport system, the laser cutting tool comprising a memory, a coordinate system, a scan head, and a laser source for generating a laser beam directed by the scan head, wherein the laser cutting tool is configured to
- accept the edible decorating sheet transported by the transport system within a cutting chamber of the laser cutting tool;
- wherein the at least one controller is configured to create a plurality of edible decorations from the edible decorating sheet by directing the laser cutting tool to
- ablate channels through the one or more layers of edible material and into the backing substrate, thereby substantially separating each edible decoration from the edible decorating sheet, and
- ablate a respective pattern on each edible decoration of the plurality of edible decorations while controlling a depth of ablation by the laser beam to maintain the backing substrate intact beneath a path of the respective pattern, wherein,
- for each decoration of the plurality of edible decorations, directing the laser cutting tool to ablate the respective pattern comprises directing, via the coordinate system, the scan head to follow a respective cutting design stored to the memory of the laser cutting tool;
- wherein, after creating the plurality of edible decorations, the transport system transports the plurality of edible decorations out of the cutting chamber of the laser cutting tool;
- and
- wherein each edible decoration is removable from the backing substrate by peeling the backing substrate away from the edible material.
A system for producing edible decorations, the system comprising:
- at least one controller;
- a transport system for transporting an edible decorating sheet comprising one or more layers of edible material deposited on a backing substrate, wherein
- the backing substrate comprises a series of traction marks scored into a surface opposite the one or more layers of edible material for maintaining traction with the transport system;
- and
- a laser cutting tool positioned along the transport system, the laser cutting tool comprising a memory, a coordinate system, an optical sensor, a scan head, and a laser source for generating a laser beam directed by the scan head, wherein the laser cutting tool is configured to accept the edible decorating sheet transported by the transport system within a cutting chamber of the laser cutting tool;
- wherein the at least one controller is configured to direct the laser cutting tool to determine, by the optical sensor, a spatial position of at least one feature of the edible decorating sheet,
- register spatial positions on the edible decorating sheet with the coordinate system using the spatial position of the at least one feature, and
- create a plurality of edible decorations from the edible decorating sheet by
- ablating channels through the one or more layers of edible material with the laser beam, thereby substantially separating each edible decoration from neighboring edible material on the edible decorating sheet, wherein,
- for each decoration of the plurality of edible decorations, ablating the channels comprises directing, via the coordinate system, the scan head to follow a respective cutting design stored to the memory of the laser cutting tool;
- and
- wherein, after creating the plurality of edible decorations, the transport system transports the plurality of edible decorations out of the cutting chamber of the laser cutting tool.
A system comprising:
- at least one controller;
- and
- a plurality of production stages for producing edible decorations, the production stages comprising
- a trimming stage comprising a first laser cutting tool, the first laser cutting tool configured to
- accept an edible decorating sheet comprising one or more layers of edible material deposited on a backing substrate, and
- an edible decoration creating stage comprising a second laser cutting tool, the edible decoration creating stage comprising
- a scan head,
- a laser source for generating a laser beam directed by the scan head,
- a coordinate system, and
- a memory;
- wherein
- the at least one controller is configured to
- 1) direct the first laser cutting tool to form, from the edible decorating sheet, a plurality of edible decoration blanks, and
- 2) direct the second laser cutting tool to create a plurality of edible decorations from the edible decorating sheet by ablating channels through the one or more layers of edible material with the laser source of the second laser cutting tool, wherein,
- for each decoration of the plurality of edible decorations, ablating the channels comprises directing, via the coordinate system of the second laser cutting tool, the scan head to follow a respective cutting design stored to the memory of the second laser cutting tool.
