This disclosure relates, in general, to methods and apparatuses for applying labels to various items.
Labels are commonly applied to various articles, including containers, to indicate the contents of the container and/or to provide other information about the article or container. Conventional labeling devices, however, are not well-suited for applying labels to articles or containers of different sizes or shapes. For this reason, multiple labeling devices are generally required to apply labels to articles of different shapes and sizes.
Since multiple labeling devices are required to label different size articles or containers, the cost associated with labeling various types of articles and containers can be significant. In addition, the use of multiple labeling devices can greatly reduce the speed in which labels can be applied, since the operator must constantly switch between different labeling devices when applying labels to articles of different shapes and/or sizes.
The systems and methods described herein provide a labeling system with great flexibility because the system can accommodate articles of various shapes and sizes. In one embodiment, a method of applying a label to an article is provided. The method includes positioning an article within a label applicator and securing the article between a first roller, a second roller, and a moveable contact member. The article is secured by moving the moveable contact member from a first position in which the moveable contact member is not in contact with the article to a second position in which the moveable contact member is in contact with the article. A label is received for application to the article and the label is delivered between the article and at least one of the first roller, second roller, and the moveable contact member. The label has a first side with printed matter thereon and a second side configured for attachment to a surface of the article. At least one of the first roller, second roller, and the moveable contact member is rotated to cause the article to rotate and the label is applied to the article as the label is delivered between the article and the at least one of the first roller, second roller, and the moveable contact member. The first side of the label contacts at least one of the first roller, second roller, and moveable contact member, and the second side of the label contacts the surface of the article. In some instances, the moveable contact member can be a moveable third roller.
The act of rotating at least one of the first roller, second roller, and the moveable contact member to cause the article to rotate can be achieved by rotating a drive shaft coupled to a drive belt to drive at least one of the first roller, second roller, and the moveable contact member. The drive belt can be configured to drive at least the moveable contact member. In some instances, the label is a pressure-sensitive label that has been cut and stripped of a release backing so that it can be applied to the article. The act of delivering the label can also include guiding the label between the article and at least one of the first roller, second roller, and the moveable contact member by directing air at the label.
The method can further include detecting the presence of the article in the label applicator using a first sensor and/or detecting the presence of the label as it is received for application to the article using a second sensor. In some instances, the rotation of at least one of the first roller, second roller, and the moveable contact member can be controlled based on information received from the first and second sensors. The article can be supported within the label applicator by moving a moveable platform into a first position onto which the article can be supported as the article is positioned in the label applicator. The labeled article can be discharged from the label applicator by moving the moveable platform into a second position after the label is applied to the article, wherein the moveable platform does not support the article in the second position.
In another embodiment, an apparatus for attaching labels to articles is provided. The apparatus can include a first roller, a second roller, a moveable contact member, an actuator configured to move the moveable contact member from a first position to a second position, and a label inlet opening for receiving a label. An article-receiving area and a label-receiving area can be provided. The article-receiving area is defined by an area between the first roller, the second roller, and the moveable contact member when the moveable contact member is in the first position. The article-receiving area is sized to receive an article without contacting each of the first roller, the second roller, and the moveable contact member at the same time. In other words, at least one of the first roller, second roller, and moveable contact member are spaced from the article when the moveable contact member is in the first position. The label-receiving area is defined by the area between the first roller, the second roller, and the moveable contact member when the moveable contact member is in the second position. The label-receiving area is sized to hold the article in contact with each of the first roller, the second roller, and the moveable contact member. The label-receiving area can be smaller than the article-receiving area, and the moveable contact member can comprise a third roller.
In other embodiments, a motor and at least one drive belt can be provided. The drive belt can be configured to cause at least one of the first roller, the second roller, and the moveable contact member to rotate. One or more sensors can be provided. For example, a first sensor can be positioned adjacent the article-receiving area and configured to detect the presence of an article within the article-receiving area. A second sensor can be positioned adjacent the label inlet opening and configured to detect the presence of a label in the vicinity of the label inlet opening. In some embodiments, a control system is provided for controlling the movement of the actuator based on information received from the first and second sensors.
In other embodiments, a platform can be provided that is moveable between a first position and a second position. An opening can be located beneath the platform when the platform is in the first position. In the first position, the platform is positioned to support an article and, in the second position, the platform does not support the article, thereby permitting the article to pass through the opening.
In another embodiment, a labeling system is provided. The system includes a label generating device configured to generate labels with a first side of printed matter and a second side with a pressure-sensitive adhesive, and at least three rollers that are spaced apart from one another to define an article-receiving area that is sized to receive an article. A label guide member can be configured to direct a label from the label generating device toward one of the at least three rollers, and one of the three rollers can be a moveable roller that is configured to move from a first position to a second position to reduce the size of the article-receiving area.
In some embodiments, the label generating device can be configured to cut labels from a continuous roll of label material and strip a release backing from the continuous roll of label material. Sensors can also be provided. For example, at least one sensor can be configured to detect the presence of an article positioned within the labeling system. A control system can be configured to control the delivery of labels from the labeling system based on a response received from the at least one sensor, the control system being configured to control the movement of the moveable roller between the first and second positions. The labeling system can also include a motor and at least one drive belt, with the drive belt being configured to cause at least one of the three rollers to rotate when the moveable roller is in the second position.

Referring to
Label 12 can be prepared and delivered to label applicator 10 by a label generating device 22 (shown, e.g., in
Label generating device 22 can have a cutting tool that can cut one or more labels from a continuous roll of label material. In addition, if the roll of label material comprises a release material or other such backing materials on second side 18, label generating device 22 can have a stripping tool to remove the backing from the label prior to delivery of the label to label applicator 10. Thus, for example, if label 12 is formed from a roll of pressure-sensitive material with release material covering the pressure-sensitive side of the pressure-sensitive material, after the label is printed, label generating device 22 can remove the printed portion of the label from the release material, and expel the stripped, printed label 12 through an output port 26 (see, e.g.,
Alternatively, it should be understood that the cutting and stripping of labels can be performed by label applicator 10 or by an intermediate device or system positioned between label applicator 10 and label generating device 22.
In other embodiments, one or both of the cutting and stripping systems may not be needed. For example, if the labels are formed of materials that do not require a release material and/or which are pre-cut and therefore do not require further cutting and/or stripping, one or both of the cutting and stripping steps can be eliminated.
To apply a label 12 to article 14, article 14 is inserted into an article-receiving area within label applicator 10. Moveable contact member 30 is then moved towards article 14 until moveable contact member 30 contacts article 14. For example, as shown in
The article-receiving area can generally be defined as an area between first roller 32, second roller 34, and moveable contact member 30 when moveable contact member 30 is in the first position (
As shown in
At least one of the three rollers (i.e., first roller 32, second roller 34, and moveable contact member 30) comprises a drive roller which receives a driving force that cause that roller to rotate. For example, as shown in
In the exemplary embodiment shown in
Accordingly, as label 12 is delivered into opening 24 of label applicator 10, the second side 18 of label 12 is brought into contact with the outer surface 20 of article 14. As the drive rollers (e.g., first roller 32 and moveable contact member 30) cause article 14 to rotate in a counterclockwise direction, label 14 is squeezed between the outer surface 20 of article 14 and the external surface of first roller 32 and label 12 is coupled to the article.
Label 12 can be formed any desired length and width. Thus, for example, label 12 can be sized to surrounds at least a portion of article 14.
If desired, a label guide 54 can be provided to help guide label 12 into a desired position. For example, as shown in
Movement of moveable contact member 30 between the first position (for receiving an article as shown in
Specific construction and operation of the actuating mechanism 55 can vary so long as the mechanism is capable of moving the moveable contact member 30 between a position that allows greater access to the label-receiving area and a position whereby the moveable contact member 30 is in contact with an article received in the label-receiving area. For example, moveable contact member 30 can be moveable along different trajectories between the first and second positions, including, for example, straight or curved trajectories. In some embodiments, the moveable contact member 30 can be biased towards the second position and the actuating mechanism can be configured to “hold-back” the moveable contact member 30 when it is in the first position.
Thus, as shown in
As shown in
Although in some embodiments moveable contact member 30 and moveable platform 37 can be manually operable, label applicator 10 desirably comprises a control system for controlling the operation of the system. Thus, for example, the control system can control one or more of the actuating mechanism (including the movement of the moveable contact member 30), the label guide, the motor, and the delivery of the label to the label applicator. In some embodiments, the control system can comprise a microprocessor, input/output controls, a programmable logic controller (PLC), or similar control mechanisms.
In some embodiments, the label applicator can include one or more sensors to improve operation of the control system. For example, a label detection sensor 60 can be positioned adjacent the opening 24 to detect the presence of a label 12 entering label applicator 10. Label detection sensor 60 can inform the system that a label is in position and ready to be applied to an article. Also, an article detection sensor 62 can be positioned adjacent the label-receiving area to detect the presence of an article 14 in label applicator 10. Article detection sensor 62 can inform the control system when an article 14 has been placed into and/or removed from label applicator 10. The sensors used by the label applicator can vary. In some embodiments, for example, the sensor can comprise an IR sensor or other photoelectric sensors.
In some embodiments, the control system can utilize the sensors to determine the presence of an article and/or the availability of a label, thereby causing the system to take actions associated with applying the label to the article in response to those determinations. Thus, for example, the system can be configured to turn on the motor and begin driving one or more of the rollers upon detecting that an article is in the label-receiving area and a label is ready for application to the article.
In some embodiments, the control system can further control the speed at which the rollers rotate. In this manner, the control system can be configured to adjust the speed of the rollers to generally match the speed at which label generating device 22 discharges labels. In this manner, smooth and efficient label application can be achieved.
Label applicator 10 can be constructed of various materials so long as those materials are sufficiently rigid and strong to perform the methods of label application that are described herein. For example, in some embodiments, label applicator is formed of aluminum or other high-strength metals, plastics, or composite materials.
Although first and second rollers 32, 34 are illustrated as being fixed in
As discussed above, various aspects of the label application process can be automated or computer controlled. In addition to those aspects discussed above, including, for example, controlling the feeding of labels, the movement of the moveable contact member, and the rotation of rollers to effect labeling of the articles, other aspects can be automated. For example, it should be understood that articles can be positioned within the label applicator in an automated manner. Thus, for example, a robotic system can be configured to position articles within the article-receiving area and remove those articles, either from the same direction from which the article was positioned within the label applicator or from another direction as described elsewhere herein.
In view of the many possible embodiments to which the principles of the disclosed invention may be applied, it should be recognized that the illustrated embodiments are only preferred examples of the invention and should not be taken as limiting the scope of the invention. Rather, the scope of the invention is defined by the following claims. I therefore claim as my invention all that comes within the scope and spirit of these claims.
This application claims the benefit of U.S. Provisional Application No. 61/382,992, filed on Sep. 15, 2010 and incorporated herein by reference in its entirety.
