The present invention relates to a system and method for the activation and application of labels, and more particularly to the preparation and activation application of multi-part labels that can indicate elapsed time and/or temperature variations from a point of activation.
There are a number of different conventional labeling systems for applying gummed or adhesive-backed labels to packaging or other desired locations. The conventional labeling systems are designed to operate with conventional labels.
Typically, conventional labels have an adhesive backing and they are formed on a continuous carrier strip often bundled around a reel. The conventional labeling device for mass application of labels consists of a machine supporting a supply of adhesive backed labels that applies the labels while feeding the carrier strip from the supply reel to a take-up reel. The system typically includes a means for applying the labels to a desired location on the package or product, using a device to remove the label from the carrier. As the labels are transferred from the carrier strip to the desired location, the carrier strip continues on, to be collected at the take-up reel.
Conventional label application systems apply a label to a location, and then move on to another location for subsequent label application. This can be done either by moving the label application mechanism, or by moving the location, such as by moving a series of packages along a conveyor belt through, over, or under the label applicator system.
Some label application systems are also configured to place labels onto other labels. This placement can be completed while one label is still on the carrier strip or after it is already applied to a package or location. The application of labels over pre-existing labels may be required to correct incorrect information on the pre-existing label, to place additional information on a package, or to update the label. In instances where the label is applied to a label on a carrier strip, the combined labels are then re-rolled for later application. Additional uses of multiple label applications include to add a security feature, to add a tracking device, to add a scratch-off covering, or to place a clear protection layer over a label.
However, none of the above label application methods or systems referred to are configured to combine two labels for purposes of activating a response or action and then automatically apply the combined label to the desired location, or present them for a user to apply to a desired location.
There is a need for a system and method to combine two labels for purposes of activating a response or action and then automatically apply the combined label to the desired location, or present them for a user to apply to a desired location. The present invention is directed toward further solutions to address this need.
In accordance with one embodiment of the present invention, a label activation and application system includes a label preparation mechanism for preparing a first label. A feeder supplies a second label. A combiner mechanism combines the first label with the second label to form a combined label. An applicator applies the combined label to a targeted location, if desired.
In accordance with aspects of the present invention, the label preparation mechanism is configured to remove the first label from a carrier strip. In addition, the combiner mechanism can be one of a merger device, a stamping applicator, or an applicator wheel.

In accordance with one embodiment of the present invention, a method of activating a chemical reaction within a label includes preparing a first label for adhesion to a second label using a preparation mechanism. The second label is provided using a feeder. The first label is adhered to the second label using a combiner mechanism to form a combined label. Adhering the first label to the second label can enable activation of a chemical reaction within the combined label.
In accordance with aspects of the method of the present invention, the chemical reaction initiates after formation of the combined label, or is activated after forming the combined label. A third label can be applied to the combined label. Preparing a first label for adhesion can include the preparation mechanism removing the first label from a carrier strip. Furthermore, applying the first label to the second label using a combiner mechanism can include utilizing one of a merger device, a stamping applicator, or an applicator wheel to mechanistically apply the first label.
The present invention will become better understood with reference to the following description and accompanying drawings, wherein:
An illustrative embodiment of the present invention relates to a system and method for the combination of multiple labels, to initiate a chemical action and form a combined label, and the subsequent application of the combined label at a targeted location. The combined label can be configured to indicate changes in such variables as elapsed time, and temperature fluctuation, over a period of time from the point of activation. The combined label can be automatically activated by the system and method for applying the labels as described herein, in accordance with the present invention.
The present invention involves a system and method for preparing a combined label 10, an example of which is shown in
In accordance with one example embodiment of the combined label 10, the combined label 10 is formed of a base adhesive layer 12, a base label 14, an adhesive/activation layer 16 and a surface label 18. It should be noted that the combined label 10 is not limited to the specific embodiment described and illustrated. Rather, the combined label 10 can have additional layers, or configurations, as understood by one of ordinary skill in the art.
Returning to the example, the base adhesive layer 12 can contain a conventional form of adhesive for applying the combined label 10 to a target location 20. The adhesive layer 12 adheres to the base label 14. The base label 14 can have a number of different configurations, and be formed of a number of different materials. For example, the base label 14 can have a standard geometric shape, or can be irregular in shape. The base label 14 can be sized and dimensioned to fit within a predetermined area at the targeted location 20. The base label 14 can be made of natural or synthetic materials, including but not limited to paper, plastic, composite, textile, mesh, and the like. In addition, the base adhesive layer 12 can cover the entirety of the base label 14 area, or can cover portions or sections of the base label 14.
The base label 14 can further include a base component or coating either mixed into the base label 14, or provided on a surface 22 of the base label 14. The base component or coating is an agent that reacts to predetermined conditions. The predetermined conditions can include physical properties, and/or the application or exposure of the agent to selected chemicals or other agents. The base component or coating can further include an adhesive component, if desired, to aid in adhering the base label 14 to the surface label 18, such as for example, in the instance of contact cement.
In the example embodiment, the adhesive/activation layer 16 includes an adhesive component as well as an activation component. The adhesive component and the activation component can be the same component, or can be different components. The adhesive component works to adhere the surface label 18 to the base label 14. The adhesive component can work in conjunction with the base component or coating, if it also contains an adhesive component, such as with contact cement. Alternatively, the adhesive component of the adhesive/activation layer 16 can merely be compatible with the base label 14 and any base component or coating, to the extent that the adhesive layer will adhere to the base label 14.
The adhesive/activation layer 16 also includes an activation component. In the example embodiments, the activation component, when combined or mixed with the base label 14 or the base component or coating, activates a chemical reaction. The chemical reaction can be designed to indicate changes in a number of different properties or variables. For example, the chemical reaction can indicate the passing of time from the point that the chemical reaction began. The chemical reaction can indicate a current temperature, a change in temperature, exposure to temperature outside of predetermined ranges, and/or temperature fluctuations. The time and temperature variables can both affect the chemical reaction together. For example, the combined label 10 can be affixed to a package of fish. The label can indicate the time elapsed since the label was created, activated, and placed on the packaging. The combined label 10 can also indicate a current fish temperature. Furthermore, the label can indicate whether at any time during the label's existence on the package of fish, the temperature has increased to, or beyond, a pre-determined level. The combined label 10 can further indicate a combination of time elapsed, and temperature conditions over a period of time. Thus, the combined label 10 can estimate the freshness of the fish in the packaging by indicating the amount of time the fish has been in the packaging, and the amount of spoilage that may have occurred based on temperature of the fish during its time in the packaging. Accordingly, in such an instance, it is necessary to activate the label and apply it to the packaging within a relatively short window of time to ensure its accuracy.
It should be noted that the chemical reaction can initiate upon the adhesion of the base label 14 and the surface label 18. Alternatively, the adhesion of the base label 14 and the surface label 18 can create a resultant chemical or mixture that can subsequently be activated, such as by heat, light, oxidation, or other activator activities, which can be incorporated into the system and method of the present invention as required.
The present invention provides a system and method for creating and applying such a combined label 10, and other similar labels requiring similar preparation steps. A label activation/application system 30 is provided, an example of which is illustrated in
A second carrier strip 44 supports the base labels 14, and is supplied by a second supply reel 46. A second peel-off plate 48 peels the base labels 14, and thus the combined labels 10 as formed, from the second carrier strip 44 for application to the targeted location 20, or to hand off for subsequent application by hand or by another device. A drive section 50 drives the second carrier strip 44, which is collected by a second rewind reel 52.
A further alternative label activation/application system 70 is provided in
In all example embodiments, the label activation/application system 30, 60, and 70 creates the combined label 10 just prior to the combined label 10 being applied to the targeted location 20 or being made available for such application. Depending on the specific embodiment of the combined label 10 as discussed previously, it may be more or less time sensitive regarding the combination of the layers and the application to the packaging or targeted location. Accordingly, the specific embodiment of the label activation/application system 30, 60, and 70 can be configured to accommodate such requirements.
Whether the label activation/application system 30, 60, and 70 applies the combined label 10 directly to the targeted location, or provides the combined label 10 for subsequent application, there are a number of different methods and devices that can be used to apply the combined label 10 to the targeted location. Such different methods include but are not limited to blowing on the label, wiping on the label, rolling on the label, tamping the label, using a swing arm to move the label to the targeted location, swiping the label, using an air wand, vacuum transfer and/or application of the label, mechanical application, by user hand, using a tool, and any combination of the above.
Furthermore, it should be noted that in some embodiments of the combined label 10, the formation of the combined label 10 by hand may contaminate the chemicals located on the surface 22 of the base label, or in the adhesive/activation layer 16, which can alter the accuracy of the combined label 10. In addition, placing the separate label layers together by hand can heat the labels, causing problems with some chemicals, and possibly inadvertently activating the combined label 10 before a desired activation time. Furthermore, alignment of the multiple label layers with each other can be crucial to the subsequent effectiveness of the combined label 10. The pressure applied during the formation of the combined label 10 in some embodiments must be consistent and within predetermined ranges to ensure good activation and accurate implementation. Accordingly, using multiple different devices to form such a combined label can have drawbacks addressed by the use of the present invention. Thus, the automated formation of the combined label 10 is crucial to its successful implementation for many embodiments of the combined label 10.
It should further be noted that the combined label 10 as illustrated is shown having two label layers and two adhesive layers. However, one of ordinary skill in the art will appreciate that the combined label 10 can have multiple layers in addition to those illustrated. Accordingly, with each successive layer, an additional step of providing a carrier strip with a label layer and aligning and applying that label layer to another label layer is required. Thus, the label activation/application system 30, 60, and 70 and corresponding method of the present invention anticipate the formation of combined labels having a number of layers different from that illustrated. Accordingly, the label activation/application system 30, 60, and 70 is configured accordingly for each additional layer required to form the combined label prior to application of the combined label to the targeted location.
A second carrier strip 94 supports the base labels, and is supplied by a second supply reel 96. A second peel-off plate 98 peels the base labels, and thus the combined labels as formed, from the second carrier strip for application to the targeted location, or to hand off for subsequent application by hand or by another device. A drive section 110 drives the second carrier strip, which is collected by a second rewind reel 112.
Numerous modifications and alternative embodiments of the present invention will be apparent to those skilled in the art in view of the foregoing description. Accordingly, this description is to be construed as illustrative only and is for the purpose of teaching those skilled in the art the best mode for carrying out the present invention. Details of the structure may vary substantially without departing from the spirit of the invention, and exclusive use of all modifications that come within the scope of the disclosed invention is reserved.
