Definitions

  • the invention is generally related to labeling machinery, and in particular to adhesive application, web registration and article handling therewith.
  • a particularly cost-effective manner of labeling beverage containers utilizes a continuous web of pre-printed polymer label material that is cut into predetermined lengths, supplied with adhesive, and applied directly to the surface of a container. Adhesive costs may also be reduced by applying adhesive only to the leading and trailing edges of individual labels and wrapping the labels completely around the containers.
  • Label machines have been developed that are capable of relatively high-speed operation, e.g., as high as 750 containers/minute or more. However, such machines have been found to be limited in several respects.
  • a turret is typically a rotatable body that includes mechanisms disposed about the periphery for gripping articles from the top and bottom ends thereof.
  • a star wheel is typically a rotatable body that includes pockets disposed around its periphery that contact the sides of articles to advance the articles through the machine.
  • Articles moving past a transfer drum are typically rotated as they pass the transfer drum (e.g., by virtue of contact between the drum and a fixed guide) so that labels on the drum are wrapped around the articles.
  • Turrets typically provide the greatest degree of precision in handling and transporting articles. However, due to the additional components and coordinated movements required to bring top and/or bottom gripping mechanisms into contact with articles, turrets are relatively slow and expensive. Star wheels are typically faster and less expensive, but have the drawback that articles are not held as securely and can become misaligned within the star wheels.
  • star wheels are typically used in conjunction with a moving conveyor that supports the articles and moves at a fixed linear velocity.
  • a label transfer drum then rotates with its outer surface traveling in the same direction as the conveyor.
  • the velocities of the pockets in the star wheel and the outer surface of the drum are typically matched so that an article contacts a label on the drum while each is traveling at the same velocity.
  • the articles may also be rolled or spun about its longitudinal axis to wrap the label around the article — typically by passing the article by a fixed guide or contacting the article with a relatively faster-moving belt.
  • Some conventional designs also incorporate feed screws at the entry and/or discharge ends of a label application station to convey the articles in a linear direction.
  • the feed screws may also have variable pitches to control the linear velocity of the articles, and thus the separation between articles.
  • feed screws also are unable to accurately control the rotational rates of articles, and thus, label mis-registration and/or article jams still remain a significant concern.
  • Pressurized air is also used in some labeling machinery to improve label control.
  • pressurized air directed toward the leading edge of a label may be used to assist in directing the label from a cutter drum to a transport drum after the label has been severed from a web, or to assist in directing the label from a transport drum to the surface of a container.
  • pressurized air may be supplied to an unsupported portion of the backside of a seam formed between the leading and trailing edges of a label wrapped around a non-cylindrical article, to strengthen the bond between the leading and trailing edges.
  • Adhesive applicators used are typically utilized to deposit an adhesive material such as a hot melt or pressure sensitive glue composition to a label immediately prior to placing the label on a container.
  • adhesive applicators include an adhesive roller that forms a nip with a label transport mechanism such as a vacuum drum, and that is supplied with a source of adhesive on its outer periphery such that adhesive is applied to a label supported on the transport mechanism as the label is fed past the adhesive roller.
  • One difficulty associated with conventional adhesive applicators is that the leading edge of a label can in some instances separate from the surface of the transport mechanism and follow the adhesive roller as the leading edge of the label exits the nip formed by the adhesive roller and the underlying transport mechanism. When this occurs, the label will often jam the adhesive applicator and the remainder of the labeling machinery, resulting in defective product and downtime associated with cleaning and restarting the machine.
  • some adhesive applicators utilize mechanical devices such as a series of parallel wires adjacent an adhesive roller to keep the leading edge of a label from wrapping around the roller.
  • the parallel wires leave undesirable patterns on the adhesive applied to each label.
  • glue droplets on the wires can contaminate both the labels and the transport mechanism. Misadjusted wires can also wrinkle or displace labels on the transport mechanism, resulting in defective labeled articles.
  • Another difficulty associated with conventional adhesive applicators is the overspray of adhesive that often occurs during the application of adhesive to the trailing edge of a label.
  • the trailing edge (which is supported on the surface of the transport mechanism) may be separated from the roller by a gap across which excess adhesive may spray.
  • a portion of the adhesive may deposit on the surface of the transport mechanism, resulting in contamination of the mechanism.
  • the transport mechanism may jam and halt the machine, requiring a more extensive and time consuming cleaning and restart operation. Given that any downtime negatively impacts the efficiency and productivity of labeling machinery, cleaning operations of any type are often highly undesirable.
  • Containers are typically fed to and from a labeling machine via a conveyor.
  • Infeed and discharge mechanisms are typically used to transport containers from the conveyor, past a label transport mechanism, and back onto the conveyor.
  • Starwheels are toothed wheels that carry containers around an arcuate guide within the gaps formed between adjacent teeth, also referred to as pockets.
  • multiple starwheels are used, e.g., where a small flow starwheel introduces initial gaps between incoming containers so that the containers can be picked up by a relatively larger infeed starwheel for transportation past a label transport drum.
  • One potential problematic characteristic of a starwheel is that in some instances gaps can exist between a container, the starwheel and the guide around which the container is transported.
  • belts may not provide adequate stability, particularly with light-weight containers having relatively high centers of gravity (e.g., unfilled two liter plastic beverage containers). Misfeeds of containers may occur, jamming the machine and requiring a time consuming cleaning and restart operation.
  • centers of gravity e.g., unfilled two liter plastic beverage containers.
  • the invention addresses these and other problems associated with the prior art by providing in one aspect an apparatus and method that utilize a rotatable drum implementing both an attraction mechanism and a cutter mechanism to controllably sever segments of material from a web.
  • the drum is rotated at a rate greater than the rate at which the web of material is advanced so that the attraction mechanism supplies the sole source of tension in the web.
  • the cutter mechanism severs segments of material while at least a portion of the web of material engages the outer surface of the drum.
  • the outer surface of the drum tends to slide relative to the leading edge of the web, with the attraction mechanism operating to apply a controlled pulling force thereto.
  • this permits less-expensive stretchable web material to be utilized, thereby lowering material costs.
  • greater reliability at high speeds is also often realized — an important consideration for many just-in-time manufacturing applications.
  • the invention also addresses additional problems associated with the prior art by providing in another aspect an apparatus and method that dynamically control the relative rates of advancement of a web of material and an outer surface of a drum such that a predetermined length of material is advanced forward of a predetermined rotational position of the drum so that the predetermined length of material is severed from the web of material while at least a portion of the web of material engages the outer surface of the drum.
  • the rate of advancement of the outer surface of the drum is different from that of the web of material such that relative slippage of the web of material and the outer surface of the drum is provided.
  • a web of material may be controllably severed into predetermined lengths using a relatively mechanically-simple configuration, which aids in accuracy and reliability, particularly in high speed applications.
  • the invention further addresses additional problems associated with the prior art by providing in another aspect an apparatus and method that utilize a carrier mechanism having at least one article carrier pivotably coupled to a rotatable hub and controlled via a camming mechanism that varies the angular velocity of the article carrier relative to that of the hub.
  • the article carrier is configured to receive and transfer an article along an article engaging surface of a fixed guide.
  • the hub rotates about a first axis, and the pivotal coupling between the article carrier and the hub defines a second axis that is substantially parallel to and separated from the first axis.
  • the camming mechanism is operatively coupled between the article carrier and the hub and configured to pivot the article carrier about the second axis in response to rotation of the hub about the first axis to thereby vary the angular velocity of the article carrier relative to that of the hub.
  • the carrier mechanism may be configured to match predetermined transport parameters associated with each of first and second stations that the carrier mechanism transports articles between.
  • the predetermined transport parameters may be based upon the pitch between sequential articles processed by each of the first and second stations so that the pitch of the articles transported by the carrier mechanism may be controlled to match that expected by each of the stations.
  • the predetermined transport parameters may be based upon the velocity of each article processed by the first and second stations so that the velocities of the articles transported by the carrier mechanism may be controlled to match those expected by each of the stations.
  • a fluid dispenser is used in connection with an adhesive applicator to improve the reliability of label feed by a label transport mechanism during the application of adhesive to a label.
  • the fluid dispenser is configured to direct a flow of fluid toward a nip formed between an adhesive roller on the applicator and the label transport mechanism, and from a position upstream from the nip.
  • a starwheel including a rotatable hub and an engagement surface defining a pocket configured to engage an article.
  • the engagement surface is resiliently coupled to the rotatable hub to move between first and second positions to vary a rotational position of the pocket relative to the hub.
  • the starwheel may be used to control the flow of articles to a second, infeed starwheel in a labeling machine in such as manner that the clearance between the articles and the infeed components is minimized, thereby reducing article vibrations and improving stability.
  • a discharge starwheel is utilized to transfer articles from the discharge end of an arcuate guide that opposes a label transfer drum.
  • the drum and arcuate guide adhere a label to an article by cooperatively wrapping the label around the article as the article rolls between the drum and arcuate guide.
  • careful control of configuration of the pockets on the discharge starwheel can improve the stability of discharged articles through reducing the spin imparted on articles by the label application process and/or decelerating the articles for pickup by a downstream discharge mechanism.
  • a discharge starwheel may be utilized intermediate a label application station and a conveyor.
  • the discharge starwheel may include a plurality of teeth defined about a perimeter thereof, with each tooth having a profile that decreases the separation between successive articles between the label application station and the conveyor. By reducing the separation between articles, greater stability on a conveyor may be obtained, as adjacent articles tend to support one another downstream of the label application station.

  • Fig. 1 illustrates a labeling apparatus 10 consistent with the principles of the invention.
  • Apparatus 10 is principally used to apply labels in a continuous fashion to a plurality of articles 2 conveyed via an article transport mechanism (e.g., a conveyor 22) from an entrance end 22a to an exit or discharge end 22b.
  • Apparatus 10 may be utilized with any number of article designs, including various containers with upright cylindrical portions, e.g., cans or bottles.
  • the articles may be suitable for use in packaging beverages or foodstuffs, or any other type of packaged goods.
  • one suitable application of apparatus 10 is in applying labels to single-serving plastic soft drink bottles, among others.
  • Articles 2 are conveyed past a label application assembly or mechanism 25 using a pair of carrier mechanisms 400, 460, which are described in greater detail below.
  • Carrier mechanism 400 transfers articles 2 along an arcuate guide 14 to a label application station 20 disposed opposite assembly 25.
  • carrier mechanism 400 operates to vary the separation between successive articles passing through guide 14 between a first separation proximate entrance end 22a to a second separation proximate station 20 that is dependent upon the separation between labels provided on an applicator drum 100 in label application assembly 25.
  • Application station 20 includes an arcuate guide 18 against which the articles are compressed by applicator drum 100 as labels are applied to the articles.
  • Guide 18 includes a resilient friction surface to impart a rolling action to the articles as the articles pass through the label application station such that labels are wrapped around the articles.
  • Carrier mechanism 460 performs essentially the same operation as carrier mechanism 400 except that mechanism 460 operates to decelerate articles from a first predetermined separation that matches the separation of labels on applicator drum 100 to a second predetermined separation suitable for transport on conveyor 22. By doing so, this arrangement imparts greater stability to discharged articles by minimizing relative movement of the articles to the conveyor at the discharge end of track 16.
  • Labels are supplied to applicator drum 100 from a web supply 30 supplying a web 4 of labeling material.
  • web 4 includes a pre-printed polymer material formed of a polymer such as polyethylene.
  • Other materials including polymers such as polypropylene and polystyrene (among others) may also be used, although polyethylene has the additional advantage in that it is significantly less expensive than other polymers.
  • Polyethylene film tends to be more stretchable than other polymer films.
  • Web supply 30 includes a pair of supply rolls 32, 34 that supply web 4 to a measuring roller assembly 50. Only one of supply rolls 32, 34 is active at any time, and a conventional change-over mechanism (not shown) may be used to switch between the rolls with minimal down time.
  • Measuring roller assembly 50 operates as a linear feed rate sensor using a free-wheeling roller 52 coupled to a rotational position sensor 54.
  • Roller 52 has a known diameter such that the linear velocity of the outer surface thereof, and thus the linear feed rate of the web, may be calculated directly from the rotational speed of the roller.
  • Sensor 54 may be any known rotational position sensor, e.g., an optical encoder.
  • Web 4 proceeds from assembly 50 to a web tracking control assembly 60 that is utilized to maintain lateral alignment of the web in assembly 25. Web 4 then proceeds to a registration sensor station 70 that detects the position of registration marks disposed on the web. Station 70 includes a roller 72 and a registration sensor 74 disposed opposite roller 72 at a lateral position relative to the web to detect registration marks disposed thereon. Registration sensor 74 may be positioned at practically any point between web supply 30 and applicator drum 100 in the alternative.

  • An adhesive station assembly 90 is disposed beyond cutting station 80 to apply adhesive to leading and trailing ends of each label using an application roller 92.
  • adhesive is applied to the leading edge of the label prior to severing the label from web 4, such that the tension within the web assists in maintaining the leading edge of the label on the outer surface of applicator drum 100 as adhesive is applied to the leading edge thereof.

  • Label Application Assembly Fig. 2 illustrates the primary components involved in supplying and severing labels from web 4 in a controlled manner.
  • Assembly 25 is under the control of a control system 200, which operates to control the supply rate of web 4 relative to the rotation of applicator drum 100.

  • the rate of rotation of drum 100 is measured via a rotational position sensor 88, which may be any type of known rotational position sensor such as an optical encoder.
  • Control system 200 also receives the output of sensor 54 to generate therefrom a measurement of the linear feed rate of web 4.
  • Control system 200 also receives a registration signal from registration sensor 74.
  • control system 200 controls a drive motor 36 to control the rate of rotation of supply roll 32, and thus the feed rate of web 4.

  • An applicator roller (not shown in Figs. 3 and 4) is offset from outer surface 104 such a distance that label material supported on any pad 110-113 will be compressed against the roller, but material disposed between the pads will not. Thus, adhesive is applied only to the material supported on a pad.
  • drum body 102 is a changeable component such that different predetermined lengths of labels may be accommodated in apparatus 10. Different lengths of labels are accommodated by utilizing different relative spacing between pads 110 and 111, and between pads 112 and 113.

Abstract

D'après cette invention, des mécanismes d'attraction (106) et de coupe (130, 170) sont utilisés sur un tambour rotatif (100) afin de découper des segments de matériau de manière commandée dans une bande continue (4). Le tambour (100) tourne à une plus grande vitesse que la bande continue (4) de manière à conférer une tension à cette dernière. On peut également utiliser un mécanisme porteur (400, 460) comprenant au moins un porteur d'article (410a 410e) qui est couplé pivotant à un moyeu rotatif (409) et qui est commandé par un mécanisme à cames (429, 442). On peut également utiliser un distributeur de fluide (1094) afin de diriger un flux de fluide vers un espacement (1178) formé entre un rouleau d'adhésif (1092) et le tambour (1038), ceci depuis une position située en amont dudit espacement (1178). On peut en outre utiliser une roue d'échappement (1020) comprenant un moyeu rotatif (1204) ainsi qu'une surface de contact (1208, 1210) qui y est couplée de manière élastique et qui définit une pochette (1204) venant en contact avec un article. Une roue d'échappement et de déchargement (1042) peut enfin être utilisée afin de transférer les articles depuis l'extrémité de déchargement d'un guide arqué (1040) qui fait face au tambour de transfert d'étiquettes (1038).
