Definitions

  • the present invention overcomes the foregoing described iifficulties in providing for the utilization of lightweight or flimsy paper-type tapes carrying an adhesive-coated layer on one face thereof by allowing for activation of the adhesive while at the same time ensuring smooth and unimpeded transport of the tape through the tape feeding mechanism immediately prior to the carton sealing unit at which a finite length of tape is actually secured to the carton to effect closure of same.
  • the present invention provides a method and apparatus for feeding lengths of carton sealing tape, e.g., tapes of the "flimsy" paper type as well as other heavier tape types to a carton sealing operation.
  • sealing tape which has an uncoated back side and an activatable adhesive layer on the front side thereof, is fed from a continuous supply thereof; such as a roll of such tape, along a predetermined travel course.
  • travel course may involve a number of alterations in the tape travel direction, but at least a segment of such travel course is required to be in a straight line path.
  • the tape While the tape is transiting the straight line travel path, the same is distended into an arcuate shape condition so that the major portion of the tape extends laterally of the straight line travel path and also such that the adhesive carrying front side is disposed in a concave disposition. While the tape is in its distended condition and at location a distance in advance of the end of the straight line travel path, that is, intermediate the ends of the straight line travel path, the tape is severed with a cutting action directed crosswise of the tape travel path to provide a finite length section of the tape. Further, and while the tape is still in its distended condition, the adhesive on the front side of the tape length is activated by passing the said front side in contact with an activating unit. In connection with the utilization of tape embodying a water-activated adhesive therein, the same can be activated with a brush unit that engages against the front side of the face to moisten the adhesive layer.
  • the apparatus provided by the present invention includes an elongated housing which is provided with a tape feed through lpassage generally extending from one end of the housing to the other, the housing passage being provided in arcuate shape form so that the travel of the tape through the passage will cause it to assume a distended condition.
  • This distended condition of the tape in effect increases the section modulus of the same thereby stiffening same and reducing, if not completely eliminating, the tendency of the tape to fold along its longitudinal axis. This is particularly important inasmuch as flimsy tape of the sixty-pound or lighter paper weight type is readily susceptible to folding into a number of pleats along its longitudinal axis when the same is fed in a purely flat condition through a tape feeding mechanism or adhesive actuating component.
  • Means are provided in the housing to effect feed of the tape therethrough and such means conveniently can be provided in the form of a drive roller and a companion friction roller unit, each of which is disposed in the housing such that during their rotation, peripheral portions thereof extend into the housing passage to engage the tape and thereby feed same through the : housing.
  • the feeding of the tape through the feeding mechanism involves supplying a continuous length feed thereof to the feed mechanism and since a finite length section thereof only should be provided to the carton sealing operation, means are provided in the housing to sever the tape at a predetermined time and thus provide a finite length section of the same.
  • the severing means can be provided in the form of movable and fixed knife 'members disposed within the housing at a location intermediate the ends of the passageway, with the movable knife being stroked in timed relationship to bring its cutting edge in a cutting traveling course across a cutting or anvil edge on the fixed knife component to thereby sever the tape.
  • the movable knife may be provided with a substantially straight line cutting edge, whereas, it is advantageous to provide the fixed knife with an arcuate profile corresponding to the shape of the passage in the housing and thereby providing that the tape is severed at its marginal portions first and then inwardly along a cutting line progressively directed towards the longitudinal centerline of the tape, the tape remaining in its distended condition during the time same is being severed.
  • adhesive activating means in the form of a brush disposed in a pot member, the tip ends of the bristles of the brush being disposed in the passageway and the pot functioning as a reservoir for holding the activating agent, i.e., water.
  • FIGURE 1 there is depicted thereir the manner in which carton sealing tape 5 is fed to a carton sealing operation in accordance with the present invention and employing the apparatus of the invention.
  • the apparatus 10 includes a housing 16 which housing includes a main housing part generally denoted at 18 and a door part 20 hingedly connected to the main housing part as at 22 and 24 (FIGURE 3) the door being shown in closed position in FIGURE 1 and in its open position in FIGURE 5.
  • the main housing part 18 has a front wall 26 which is of convex arcuate configuration and which defines one wide boundary of the-tape feed through passage 12 formed in the housing, the other boundary of such passage being defined by the concave arcuate shaped face 28 of the door 20 and which juxtaposes spacedly from the front wall 26 of housing part 18 when the door 20 is closed.
  • the passageway 12 thus formed in the housing is as indicated of arcuate profile and'extends fully through the housing from the upper to lower ends thereof along a substantially straight line course providing that the continuous length of tape entering the housing transits such a straight line travel course but is held in a distended condition in which it is arcuately curved outwardly from the straight line travel course and most readily discerned with reference to FIGURE 2.
  • the travelling mass thereof is rigidified, it being believed that by thus enhancing the section modules, the tape is more readily and conveniently severed as well ,as fed through the housing without hazard that the same will be caused to become wrinkled or accordion folded along its longitudinal length which condition could lead to jamming of the apparatus as well as failure to properly activate the adhesive face thereof.
  • the feeding of the tape through the housing 16 is accomplished by means of a feed roller 30 rotatable about a fixed taxis in the housing main part 18 and driven by a motor 32 (FIGURE 2), and a complementary or friction roller 34.
  • the feed roller which has a knurled peripheral surface as at 36 is, as noted, mounted in the main housing part, whereas, friction roller 34 is mounted on the door part 20 and the two have when the door is closed a peripheral rotary travel course such that each extends a distance into the passage 12 to engage the tape 5 and thus feed same through the housing.
  • Both the housing wall 26 and door part 20 are slotted as at 38, 40 respectively to accommodate the rollers.
  • the friction roller 34 is carried on a mounting member 42 on the door 20, which mounting member in turn is pivoted as at 44 to the door structure. Thus,' the friction roller can be moved into and out of contact with the tape.
  • the mounting member 42 is connected to the armature 46 of a solenoid unit 48, the operation of the solenoid oscillating the mounting member 44 to thereby move the friction roller into and out of contact with the tape.
  • a cutting knife unit Disposed just below the feed and friction rollers 30, 34 is a cutting knife unit generally denominated at 60 which unit is used to effect severing of the tape.
  • the knife unit comprises a fixed knife member 62 carried in the door part 20 and provided with an arcuate shape in correspondence to the arcuate shape of the passageway 12 and provided further with a cutting edge part 64 (FIGURE 1).
  • a movable knife member 66 is carried in the main housing part 18 and is operated or reciprocated by a fluid actuated cylinder unit 68, the latter being pivoted in the housing part 18 as at 69, the movable knife being fixed to the rod 71 of the cylinder.
  • the action of the cutting knife unit is such as to effect a cutting of the distended tape first at the marginal portions thereof with such cutting action being continued progressively towards the longitudinal centerline of the tape.
  • the movable knife member 66 which moves in generally straight line has, for a substantial portion of its expanse, a straight line'cutting edge section of slightly bowed profile as at 70.
  • the marginal extremities of the movable knife at its front or cutting edge part are formed in the manner of forwardly and downwardly sloping lugs 72.
  • Further compression springs 73 carried in housing part 18 are connected to the broad blade structure of knife 66 and tend to pull the knife 66 upwardly.
  • the door 20 can be closed against the front wall 26 without hazard that the fixed knife 62 carried on the door would jam against the movable knife 66 and prevent complete door closure.
  • the movable knife cutting edge 64 engages against lugs 72 and forces them and hence the movable knife downward slightly to allow for full door closure clearance and into proper cutting edge relationship with the fixed knife member 62.
  • the front wall 26 of the housing main part 18 and the door part 20 are slotted as at 80 to accommodate passage of the movable knife therethrough.
  • the adhesive activating means 90 Disposed immediately below the cutting knife unit 60 and adjacent the lower terminal end of the housing passage straight Section is the adhesive activating means 90 the activating means assembly being shown in FIGURE 6. It will be understood that the tape passing through the feed apparatus is one which requires application of an activating agent to the adhesive layer mounted on the front face of the tape, the front face of the tape being that lying immediate the front wall of the housing main section, whereas', the rear face of the tape is juxtaposed with the wall face of the door part 20.
  • the activating means comprises a pot 92 functioning as a reservoir to hold a quantity of water.
  • a brush unit 94 Disposed within the pot and arranged at an inclination upwardly from the bottom thereof is a brush unit 94 provided with bristles the tip ends of which are disposed in the passageway 12 and conform in arcuate profile there with.
  • a brush comb assembly 95 comprised of a plurality of spaced and vertically oriented plates 96 which extend between the bristles of the brush so as to define a plurality of bundles of bristles. The plates function to rigidize the bristles to prevent deflection of same and ensure firm contact of the tip ends thereof with the adhesive face of the tape.
  • comb guard 98 which is slotted as at 102 so that same may embracingly gird the comb plates 26.
  • the positioning of the brush unit 94 can be altered to ensure proper application of water to the adhesive face of the tape by means of adjusting screw 104 which moves the brush toward and away from the passageway 12. Following the severing of the finite length section of tape and moisturizing of the adhesive layer thereon, the tape length feeds into the tape applying and wipe down unit 6 in a manner well understood by those skilled in the art and in which the tape length is applied and Tolled onto a carton for sealing same.
  • the brush comb assembly 95, plates 96 and comb guard 98 can be dispensed with without altering the effectiveness of the brush bristle tip ends with the adhesive face of the tape inasmuch as the arcuate profiling of the tip ends to conform with that of the distended tape eliminates any tendency of the bristles to spread.
  • the apparatus depicted is intended for use in conjunction with a tape applying and wipe down unit associated with applying tape to the tops of cartons.
  • Apparatus for use with tape applying and wipe down units for applying tape to the bottoms of cartons would be identical with that disclosed except the components would be arranged in a reversed orientation, i.e., the tape would feed from bottom to top, the feed and friction rollers would be at the bottom of the apparatus and the adhesive activator at the top.
