Abstract: An automatic, high speed labeling machine is provided for applying individual labels to large and variable size produce items. The label strips used are much larger and heavier than known label strips used for small produce such as apples and pears. The increased weight causes label strip overrun when the labeler is paused and also causes slippage of the label strip. A label strip deflector is provided which causes the larger and heavier label strip to fold back on itself rather than to overrun and foul the application of labels. The drive rollers are modified to eliminate slippage of the heavier label strip.

Abstract: An automatic high speed labeling machine with an improved label stripper is provided capable of applying 700 to 1,000 labels to individual produce items in a single lane, without tearing the label carrier strip. The improved label stripper has a contoured surface wherein only the center section contacts the label carrier strip. The edges of the carrier strip are prevented from contacting the label stripper surface.

Abstract: An automatic, thermal print on demand labeler is provided. The thermal print head is placed above the axis of rotation of the rotary head, with a cylindrical platen mounted horizontally opposite the print head. A stripper pin is mounted below the platen; the pin is positioned very close to the print region of the print head. This positioning of components results in a label being printed and dispensed onto a bellow in one index of the multi-bellow rotary head. Independent direct gear drive trains are provided for the rotary head and label tape drive.

Abstract: A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including preferably transparent substrate, a thermochromic layer and a light absorbent layer located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The media optimally includes obscuration materials to reduce the visibility of the light absorbent layer to the naked eye.

Abstract: A vision recognition system is provided for use with a high speed, automatic produce labeling machine. The system uses laser profiling to direct a sheet of light transversely to the longitudinal axis of a produce feed conveyor. The sheet of light periodically impacts, and generates laser profiles of, the surfaces of the produce items, such as pears, being fed by the conveyor to one or more labeling machines. The laser profiles are used to generate real world (x,y) coordinates of the domes of the incoming produce items, which are passed to the labeling machine or machines. Real world height (or z) coordinates may also be created and passed to the labeler.

Abstract: A multi-layer laminate media is provided on which information may be applied in machine or human readable form on a visible front surface by the output of one or more lasers, or other high intensity light source. In a preferred embodiment, the media has three layers including a substrate, a thermochromic layer and a light absorbent layer such as carbon black located intermediate the media substrate and the thermochromic layer. The light absorbent layer is adapted to absorb light from the light source and convert the absorbed light into heat. The heat is immediately conducted into selected portions of the thermochromic layer which is in thermal contact with the light absorbent layer, causing portions of the thermochromic layer to change visual appearance such as color to create the desired mark. The invention includes a method and apparatus for using the media in conjunction with labeling produce items.

Abstract: An automatic apparatus for applying labels to produce is provided which utilizes three or more label cassettes angularly disposed in coplanar fashion adjacent a rotary bellows applicator. The cassettes may include labels indicating different sizes or grades of produce, for example, and each produce item being labeled may have a label selected from any one of said multiple cassettes. High label speeds in excess of 1000 labels per minute are achieved along with selective labeling.

Abstract: An apparatus and method are provided for automatically labeling individual produce items. Individual produce items are conveyed towards a rotary bellows or other applicator. A sensor senses at least one variable characteristic, such as size of each of the produce items. The sensed variable is transmitted to a laser coding device and a variable human or machine readable code is printed on an individual label prior to application of that label to the specific item of produce for which the variable characteristic was sensed. The laser coding beam either reacts with a reactive or ablatable film on each label.
