Definitions

  • This invention relates generally to mechanisms for changing a web feed from intermittent to constant motion, and has to do particularly with an improved mechanism of this kind, particularly suited to working with carton board web or any other type of material being transported in unsupported web form through a cutting mechanism.
  • Carton board web after being printed, is cut and creased in a diecutter.
  • movement of the web through the diecutter is intermittent, with the web being indexed forwardly through a cycle which includes corning to a full stop to allow diecutting to take place, then advancing to bring the next portion of the web to the diecutter, then a full stop again, and so on.
  • the only means by which the cut parts (cartons) are restrained with respect to each other is via nicks that tie the parts to the scrap portion (matrix) of the cut web.
  • the liner or carrier web serves to locate the labels relative to each other.
  • parts exit at a continuous speed (which would have to be the same as the web motion at the infeed of the diecutter) instead of the stop/start motion associated with the straight exit web path format.
  • Motion at constant speed facilitates subsequent operations performed on the parts, such as: stripping, conveying and stacking (mainly because of the minimization of mechanism accelerations). For example, it is less difficult to strip cartons with a rotary device than a reciprocating device, and in addition it is faster.
  • this invention proposes an S-wrap mechanism that utilizes a dual enveloping belt arrangement to entrap the cut carton board parts as they exit from the diecutter.
  • the trapping action of the belts facilitates the transportation of the parts and related matrix through the S-path geometry that is required to produce constant output velocity of the parts.
  • Such an arrangement is able to control the position of the parts relative to each other (part-to-matrix nicks are maintained) as they travel through the S-path.
  • the latter feature may be accomplished by using very thin section belts, and by ensuring that the top belt has a much lower coefficient of friction, where it contacts the parts being guided, than does the lower belt.
  • the result of this is that the lower belt determines the motion profile, because some relative slippage between the top belt and the part/lower belt is permitted.
  • one set of top and lower belt idlers are geared together, which produces a bias that acts to synchronize the belt speeds.
  • each belt is equipped with its own lateral web guide, whereby the lateral location of each belt can be independently controlled so as to counter any steering influence from the other belt.
  • this invention provides, for use with a machine through which an elongate web passes; the machine having a stationary frame; the machine further having first means causing the web to follow, at a predetermined location, a repeating cycle of arrested motion alternating with forward motion, the first means having an exit end; the machine further having second means for performing certain operations on the web, at said predetermined location, when web motion at said location is momentarily arrested; the web retaining its alternating motion upon exiting from said second means:
  • First and second adjacent idler rollers 16 and 17 are mounted for free rotation on the carriage 15, and specifically they are located at the rightward extremity thereof.
  • a third idler roller 13 is also mounted for free rotation on the carriage 15, but is spaced leftwardly away from the two adjacent idler rollers 16 and 17, as can be seen clearly in the drawing.
  • a driven roller 19 is mounted for rotation about an axis which is fixed with respect to the machine frame, and is located with respect to the third idler roller 13 such that a web, when strung between the first and second idler roller 16 and 17, thence around the third idler roller 13, thence around the driven roller 19, assumes a quasi-boustrophedonic configuration, such that a portion of the web can be taken up between the third idler roller 13 and the driven roller 19 when the carriage 15 moves in a direction which increases the distance between the third idler roller 13 and the driven roller 19 (i.e. move to the left as pictured in the drawing).
  • the length of web taken up is equal to the length of web simultaneously paid out from the infeed carriage (not illustrated).
  • An upper endless belt 28 and a lower endless belt 29 are arranged to pass in juxtaposed relation between the first and second idler rollers 16 and 17, thence leftwardly toward the third idler roller 13, thence around the third idler roller 13, thence to and around the driven roller 19, thence along different respective return paths to the first and second idler rollers 16 and 17. More particularly, both the upper belt 28 and the lower belt 29 pass in juxtaposition from the bottom of the driven roller 19 to the space between a fourth idler roller 25 and a fifth idler roller 26, the rollers 25 and 26 being juxtaposed, at close spacing, but not providing a nip. Upon passing through the idler rollers 25 and 26, the upper and lower belts 28 and 29 separate and follow distinct paths back to the idler rollers 16 and 17, respectively.
  • the upper belt 28 partly encircles the fourth idler roller 25, then partly encircles a sixth idler roller 31 which is fixed with respect to the frame, thence around two further idler rollers 29 and 30, thence around an additional idler roller 32, from where it extends to contact the first idler roller 16.
  • the lower endless belt upon exiting leftwardly between the fourth and fifth idler rollers 25 and 26, partly encircles the fifth idler roller 26, thence passes around further idler rollers 38 and 37, and finally to the second idler roller 17.
  • rollers 13, 16 and 17 which are secured to the movable carriage 15, and with the exception of the driven rollers 19, all of the rollers are idlers which are fixed in position with respect to the frame.
  • the fourth and fifth idler rollers 25 and 26 are preferably geared together, which tends to promote synchronization of belt speeds.
  • the belts 29 and 30 be of relatively thin section, ideally in the region of about 31 thousandths of an inch. Also, the upper belt 28 has a much lower coefficient of friction then does the lower belt 29, which results in the lower belt determining the motion profile of the web.
  • the cut web is drawn into the exit section between the translating idler rollers 16 and 17 with intermittent motion, and the action of the belts 28 and 29 acting around the translating idlers 13, 16 and 17, results in the web exiting at a constant speed relative to the frame.
  • the carriage movement is toward the web entry point (rollers 16 and 17) at a velocity of one-half the web (line) speed when the web is stationary relative to the frame, and has approximately twice the web speed as it moves away from the entry point.
