Definitions

  • the system is based on a brake mechanism and a pressure roll pivoted about a common point, the former adapted to prevent transport of labels to a label dispensing element or mechanism and the latter for advancing a web or residue matrix by engagement with a constant running drum, upon release of the brake.
  • Accurate dispensing of labels using the system is achieved through alternating brake-drive of the web or matrix in combination with the maintenance of a constant tension between the brake and rewind mechanism.
  • SHEET 2 (IF 2 'F/ELE LABEL DISPENSING SYSTEM BACKGROUND OF THE INVENTION
  • the advent of the pressure sensitive label represented a new era in labeling operations in that an ability to dispense a self adhesive label from an essentially release coated carrier web eliminated most of the equipment attendant to making initially non-adhesive surfaces, such as glue, adhesive in nature by the application of a solvent, such as water.
  • the label once dispensed may be applied directly to some substrate or registered on an applicator, typically a perforated grid which draws the label to its surface by a suction pneumatically created then deposits the label on the substrate by reverse air flow through the grid or mechanical movement of the grid to the substrate.
  • an applicator typically a perforated grid which draws the label to its surface by a suction pneumatically created then deposits the label on the substrate by reverse air flow through the grid or mechanical movement of the grid to the substrate.
  • a typical way of dispensing labels is to intermittently rotate the pull roll each time a dispensing operation is called for.
  • Tensional force fluctuations may also result from the rate at which a web is passed over the edge of the dispensing blade. Additionally, fluctuations may simply be due to the change in diameter of the carrier web on the supply reel as well as the change in diameter of the collected spent web on the driven take-up roll.
  • the carrier web is often weakened due to overcuts and breaks under the more severe tensional forces which may occur during the operation of a typical label dispensing system.
  • an improved apparatus and method for accurately dispensing labels on a continuous or synchronized ba- SIS According to the present invention, there is provided an improved apparatus and method for accurately dispensing labels on a continuous or synchronized ba- SIS.
  • the apparatus of this invention may be particularly adapted for use with a conventional label supply and dispensing mechanism such as, for instance,
  • the improved label dispensing system of this invention comprises, in general, a drive roll which is adapted to be driven at a constant rate of rotation, a braking system which is adapted to engage the carrier web to prevent advancement of the web over the relatively sharp edge of the label dispensing blade, and pressure means adapted to engage the web with the driven roll to advance the web over the dispensing means whereby a label is dispensed when the brake system is disengaged.
  • the brake system and the pressure means are pivoted about a common axis for alternately engaging the brake system with the web and driving the web by forcing the web against the driven roll with the pressure means.
  • pressure sensitive labels are dispensed on what amounts to a controlled continuous or synchronous basis, by alternate application of the brake to prevent movement of the web and driving of the web by application of the web by the pressure means against the driven roll when the brake is released.
  • the preferred apparatus of this invention employs web supply reel which is provided with a biased unwind dancer roll which takes up slack in the web between the supply reel and applied brake and maintains a constant web tension between the supply reel and the brake.
  • a biased unwind dancer roll which takes up slack in the web between the supply reel and applied brake and maintains a constant web tension between the supply reel and the brake.
  • the process which employs the apparatus of this invention involves, generally, feeding a web containing pressure sensitive labels to a label dispensing edge. Altemately stopping advancement of the web to dispensing edge by application of a brake to the web surface, and drawing the web over the edge of the dispensing lip by pressurizing the web against a cylindrical surface rotating at an essentially constant speed.
  • This method dispenses labels on a continuous or synchronous basis by alternating braking and driving operations.
  • FIG. 1 is a detailed illustration of the apparatus used for dispensing labels on a continuous or synchronous basis.
  • FIG. 2 is a perspective view of labeling system in operation employing the continuous or synchronous label dispensing mechanism shown in FIG. 1.
  • the fairly conventional portion of the label dispensing apparatus 10 consists of a source of pressure sensitive labels supported by a release coated web such as supplied from reel 12 mounted on shaft 14 which may also contain, as shown, the on-off" switch 16 for starting and stopping the operation of the label dispensing system; a label dispensing lip 18 and its attending web guiding carriage 20, and wind-up roll 22 which is normally driven to take up spent tape and which may include a reel (not shown) for containing the spent web.
  • a source of pressure sensitive labels supported by a release coated web such as supplied from reel 12 mounted on shaft 14 which may also contain, as shown, the on-off" switch 16 for starting and stopping the operation of the label dispensing system
  • a label dispensing lip 18 and its attending web guiding carriage 20 which is normally driven to take up spent tape and which may include a reel (not shown) for containing the spent web.
  • wind-up roll 22 which is normally driven to take up spent tape and which may include a reel (not shown) for containing the spent web.
  • label sensing mechanism 24 which senses the presence of a pressure sensitive label 26 on web 28 in order that the dispensing of the label can be coordinated with advancing substrates to which labels are to be applied as more particularly shown in FIG. 2.
  • a feature of the label dispensing mechanism of this invention is carriage 32 which pivots about a pivot point such as pivot point 34 which may also serve (as shown) as a shaft for an idler roll 36 which aids in guiding the web from reel 12 to dispensing lip 18.
  • lower brake system 38 having at the upper surface thereof a rubber or a similar brake pad 40 and a lower brake bar 42 whichis spring-biased by plunger spring 44. This action tends to maintain the lower brake system 38 biased towards the web containing pressure sensitive labels and upper brake bar 46 to maintain the web 28 in a normally braked position.
  • adjustable eccentric stop 48 which acts on shaft 50 of upper brake bar 46.
  • Shaft 50 is normally biased against stop 48 to adjust the clearance between the upper brake bar 46 and the lower brake system 38.
  • upper bar 46 is drawn away from stop 48 by pulling handle 51.
  • stop 48 is adjusted to just contact shaft 50. Normally, the clearance for rapid stopping action is set at between about 0.007 and 0.010 inch in addition to the thickness of the web.
  • nip roll 52 Also pivoted about pivot point 34 is a pressure means shown as nip roll 52 which is in continuous contact with the web and which serves to force the web against driven roll 54 which is cylindrical in shape and rotates at essentially a constant torque and rate. This occurs when frame 32 is pivoted about pivot point 34 by some cyclic driving means such as solenoid 56.
  • web guard 60 which is normally non-rotating
  • web turnback bar 62 which is also non-rotating.
  • web snubber brush 64 which serves to impart an initial force on web 28 to aid in accurately positioning labels with respect to label sensor 24.
  • solenoid 56 When solenoid 56 is deactivated brake system 38 consisting of pad 40 and lower bar 42 are applied by the spring force of plunger 44 against web 28 and upper brake bar 46 to stop advancement of the web to dispensing blade 18. In this condition solenoid 56 is in a relaxed position and nip roll 52 is away from driven roll 54 in order that a drag will not be imparted to web 28 in the zone between nip roll 52 and driven roll 54.
  • Take-up reel 22 is normally driven by a slip drive using a belt take-off (not shown) from the motor (not shown) used to drive roll 54.
  • a secondary brake system which consists, in part, of dancer roll 65, which is rotatable, and spring biased bar 67 pivoted about axis 69.
  • dancer roll 65 which is rotatable, and spring biased bar 67 pivoted about axis 69.
  • spring biased bar 67 pivoted about axis 69.
  • This action serves as a functional brake which overcomes the tendency of take-up reel 22 to continue to rotate due to the action of the slip belt drive.
  • brake 77 an equilibrium at which take-up reel 22 is held motionless.
  • the tension in web 28 between the take-up reel 22 and the brake means will become constant by virtue of the bias force applied through roll 65.
  • roller 68 To maintain a constant tension between the brake means and the web feed reel 12, there is provided roller 68, known as a dancer roll which is mounted on spring biased bar which tends to force roller 68 upward and away from the brake means. This takes up any slack in the web between reel 12 and the brake means and provides a constant tension between these points.
  • any label such as label 58 will be dispensed at a controlled attitude or pitch for accurately positioning onto a substrate on indexing on an applicator.
  • take-up reel 22 clip 72 which initially engages the web when it is threaded through the label dispensing apparatus during startup.
  • label dispensing system of this invention may be more fully understood with reference to FIG. 2.
  • label dispensing housing 29 there may be provided a plurality of input plugs 74 which serve to receive and dispense signals which control or monitor the advancement of a substrate 76 towards the dispensing lip 18 of the label dispensing apparatus; control the function of a label applicator when used and the functional operation of label dispenser system 10.
  • bracket 32 When the dispensing of a label is called for, bracket 32 is driven downward about pivot point 34 by solenoid 56 moving the lower brake system 38 away from the upper brake bar 46. This releases the web 28 from the break means and engages the web with drive roll 54 by the pressure supplied by nip roll 52, with take-up reel 22 being driven by an internally mounted slip belt in the housing 29 of the label dispensing system to take up driven spent web. As the web passes over the edge of blade 18 a label 58 is dispensed for application to substrate 76. To prevent separation of lifting of web 28 from the surface dispensing lip 18 there is provided resilient but flexible pressure leaf 80 which maintains a positive pressure on web 28 at lip 18. Substrates shown here are a series of bottles transported under label dispensing system 10 by belt 82 with their lateral position confined by channels 84.
  • the brake means is engaged to stop advancement of the web. Advancement of another label toward blade 18 is controlled by label sensor 24 biases against back-up anvil 33 as modified by brush 64 (not shown). The presence of a label produces a signal which is fed to one of the inputs 74 of housing 29 which, in coordination with an advancing substrate causes energization of solenoid 56, which drives roll 52 in pressure contact with driven roll 54 by rotation of bracket 32 about pivot point 34.
  • solenoid 56 When the label has been dispensed solenoid 56 is deenergized and lower brake system 38 engages web 28 with upper brake bar 46 to stop web transport. This interrupts transport of the web toward label dispensing lip 18 causing dancer roll 68 to take up any slack in web 28 and dancer roll 68 and to brake the tendency of reel 12 against continued rotation.
  • the labels will be dispensed on an intermittent basis and because, as previously indicated, the web tension is maintained essentially constant the labels will be dispensed within an accuracy of from about 1*: 1/64 inch at unusually high rates.
  • guides 86 which adjust the position of web 28 relative to the advancing substrates.
  • elevation system 88 and dispenser pitch system 90 which controls the attitude of the label dispenser to a substrate by rotation about the axis of support cylinder 92.
  • An additional feature of the label dispensing system of this invention is that it is open to permit easy threading of a label carrier web through the various mechanisrm during start up operations.
  • label dispensing system of this invention has been illustrated in FIG. 2 assuring a generally vertical attitude to a substrate being labeled, a particular advantage of the system is that it may be positioned in any attitude relative to a substrate.
  • label dispensing system of this invention has been illustrated as dispensing pressure sensitive labels from a matrix-free web, the system is equally useful in dispensing labels from a matrix with or without a supporting web; supported and unsupported tapes of any length; perforated labels separated by tearing operations or the like.
  • the label dispensing system may also be operated on a continuous or intermittent basis.
  • the braking function may be interrupted, pending a disruption in the feed of substrates which requires application of the braking means and disengagement of the drive mechanism until the disruption in feed is corrected.
  • the alternating brake-drive system has been illustrated as operating using a pivoted supported structure with the movable portion of the brake disposed below an advancing web containing a group of labels, the movable portion of the brake means may be equally disposed above advancing labels and applied by a downward movement.
  • the residue following the dispenser may be braked alone or with the feed to the dispenser.
  • the former function being advantageous where the labels or the like are driven to rather than drawn past a suitable dispenser.
  • the labels or tapes may be detached by any suitable dispenser such as a direct vacuum pick-up; label or tape separation due to serrations; by in-line cutting and like functions.
  • labels, tapes or the like may be supplied externally to the label dispensing system of this invention.
  • labels may be fed as fan-folded labels with residue matrix and/or web discarded to some waste disposal system.
  • the label dispensing system of this invention is adaptive to handling a wide variety of label or tape supplies and mechanisms for dispensing them to a substrate so long as there is preserved the basic attenuating brake-drive system.
