Autonomously operated systems and methods of packing unbound folded laundry articles are described. A system of stacking a plurality of folded laundry articles onto a receiving surface includes two or more side-by-side parallel extendable surfaces configured to extend at least one of independently and simultaneously, at least one sensor configured to detect a presence of one or more folded laundry articles on at least one of the surfaces, and a controller in operative communication with at least one drive of the two or more surfaces and the at least one sensor. The controller is configured to extend a loading end of at least one of the surfaces out upon receiving a signal from the at least one sensor, and retract the loading end to deposit the one or more folded laundry articles atop at least one of the receiving surface and one or more previously deposited folded laundry articles.

A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

Devices, systems, and methods for autonomously queueing a plurality of folded laundry articles in a packing queue are described. A packing system includes a packing queue platform configured to receive a folded laundry article into one of a plurality of packing queue locations disposed along a length of the platform, a double ended conveyor, one or more sensors configured to detect a packing queue location, and a controller. The double ended conveyor includes a retrieving end and a depositing end. The conveyor is configured to be mounted to a one or more fixed rails for traveling along the length of the queue platform and cantilevering the depositing end over the packing queue platform for depositing the folded laundry article onto either a surface of the packing queue platform or another previously deposited folded laundry article of the plurality of folded laundry articles.

An execution plan segment of an execution plan can be received at a control unit of a computer numerically controlled machine from a general purpose computer. The execution plan segment can define operations for causing movement of a moveable head of the computer numerically controlled machine to deliver electromagnetic energy to effect a change in a material within an interior space of the computer numerically controlled machine. The execution plan segment can include a predefined safe pausing point from which the execution plan can be restarted while minimizing a difference in appearance of a finished work-product relative to if a pause and restart are not necessary. Operations of the computer numerically controlled machine can be commenced only after determining that the execution plan segment has been received up to and including the predefined safe pausing point by the computer numerically controlled machine.

In one aspect, the present invention relates to a contour checking device for calculating path deviations from a target path of a cutting head of a laser machine tool. The contour checking device comprises a reference texture interface for reading a reference texture along the target path, which is defined in particular for cutting a contour, a controller, which is intended for controlling the laser machine tool in such a way that the cutting head traverses the target path; at least one camera, wherein the controller for controlling the at least one camera is intended for continuously capturing overlapping frames of the reference texture along the traversed path; a processor, which is intended for executing an image processing algorithm for reconstructing the trajectory traversed by the cutting head from the captured overlapping frames of the reference texture; and wherein the processor is intended for calculating deviations between the reconstruction of the path traversed by the cutting head and the target path. The contour checking device also comprises an output interface, which is intended for outputting the calculated deviations.

A PLC system includes a displacement sensor, drives, and a PLC. In the PLC system, the trace control unit calculates a target position at which a distance between the displacement sensor and the object is constant based on measurement information (1D information) from which measurement noise (noise information) has been removed by the filter and positional information from the drives.
