Definitions

  • This invention relates to an unique, intermittently fed, rotary converting method and apparatus by which web-fed carton board material is converted into die cut and creased parts.
  • the same process has numerous potential applications in other industries where rotary converting of a web substrate is used, such as the pressure sensitive label business.
  • Board material that is printed in continuous web form can be subsequently creased and die cut in-line with the press with either a flat or rotary die cutting mechanism.
  • selection of the appropriate die cutting method is determined by the economics of the total conversion process of the print job(s) being run. Factors influencing the selection of the cutting/creasing method include: capital cost of the cutter mechanism, rooting cost, substrate thickness, tool life, change-over/make-ready time, process speed, length of the job run and toot supply lead time.
  • Each process has distinct advantages relative to the other; however, only a careful analysis of these various parameters relative to a specific print business mix can determine the best cutting method to be used. While it is possible to have both processes in-line with one printing press, this is typically not done due to the high capital cost and/or high tooling cost of such a scheme.
  • the advantages of flat cutting/creasing relative to its rotary alternative are:
  • Rotary cutting tools are supplied in marched male/female sets, most often with the creasing performed in one set with the die cutting done in a second set. Cutting and creasing can be done in one tool set, but only at increased cost relative to the split set arrangement. Either way, cost is high and lead times are long relative to flat die cutting tools.
  • the rotary sheet die format makes use of thin steel sheets (up to 0.040" thick) that are chemically etched or machined and then attached to base cylinders. Thus, the cost of replacement is limited to the sheet die itself, not the expensive base cylinder.
  • the cylinder bases effectively have an infinite life. Means of attachment of the flexible die to the base cylinder can include mechanical locks, adhesive or magnets.
  • the cost of a rotary sheet die is typically three to four times that of a flat die and has a life double that of a flat die. Therefore, the use of flexible sheet dies partially overcomes the cost objections to rotary cooling. As well, sheet die manufacturing and delivery lead-time is approximately 6 days (versus 3 days for flat dies), a significant improvement over solid rotary tool delivery lead-time.
  • print image preparation will almost always select a repeat size that economically accommodates the size and shape of the image to be printed.
  • Most flexographic printing machines for example, allow a wide range of repeat lengths, typically in 1/8 th -inch increments. This results in printers having to purchase and maintain a large inventory of print and die cut tooling.
  • die cutting each unique repeat used would require a tool of specific length. This is true for both flat and rotary die cutting.
  • Dynamic considerations of the proposed system dictate the use of a base cylinder circumference larger than the longest repeat size to be used. This being the case, there will always be a gap between the leading and trailing edges of the flexible die. Since the web carries a continuous series of successive printed images that are adjacent to each another, it can therefore be seen chat the printed web must be repositioned such that the position of each successive printed image is synchronized with the cutting pattern on the rotary tool, the repeat of which is constant but the image on which is discontinuous. The indexing of the web through the rotary cutting section is such that the web speed matches that of the rotary tool when the web is engaged with the cutting pattern on the tools.
  • the function of the injector is multi-fold:
  • the injector operates with two types of motion input; rotary for drive to the web, and linear for indexing of the web to produce the position profile necessary for the fixed diameter base rotary cutter.
  • These two motion inputs may variously be by rotary mechanical motion generators, rotary servos or linear electrical servos.
  • the fixed diameter rotary die cutter set may be operated at constant angular velocity.
  • the die cutter can be operated at a variable speed race such that accelerations of both the web and mechanism are minimized, thus allowing higher operating speeds (approximately 15% faster).
  • the injector is capable of generating the web motion necessary for synchronized cutting action of the web.
  • the proposed system may be configured in several formats, depending on the production goals of the user. These configurations are explained in the description of the drawings. Of particular interest is the version that allows for the die cutting, creasing and window stripping of the continuous web followed by rewinding of the web into roll form, as opposed to delivery of individual cartons.
  • the rolls of die cut cartons can then be introduced to the final step of the conversion process (gluing/folding) without the handling and storage expense associated with current methods.
  • handling the parts in roll format permits a condition of optimum security. Cartons need be inspected only once, on the press. Integrity is assured by the roll format.
  • the present proposal addresses the aforementioned shortcomings of the rotary die cutting process as follows:
  • this invention provides, for use with a machine through which an elongate web passes with continuous movement, the machine having means for performing a given operation on the web, said given operation lying within a predetermined repeat length, adjacent repeat lengths being separated by repeat length boundaries, the combination of:
  • this invention provides a method for handling an elongate web proceeding at uniform speed from a process in which it repeatedly undergoes a given operation, said given operation lying within a predetermined repeat length, adjacent repeat lengths being separated by repeat length boundaries, the method including: providing a rotary processing device including two rotary base rollers for positioning downstream of said process, the rollers being juxtaposed to define a nip through which said web can pass, each roller having the same circumference, said circumference exceeding the repeat length of said given operation, the rollers having secured thereto cooperating circumferential processing plates each of which includes a first portion intended to engage the web and a second portion which does not engage the web; and roller drive means for rotating the base rollers; further providing an injector mechanism adapted for positioning upstream of said rotary processing device and for receiving said web, said injector mechanism being adapted to modify the continuous movement of the web, as it comes from said process, to a variable movement; the injector mechanism including:
  • Figures 1A and 1B each show a schematic axial view of a typical rotary die cutter set.
  • the rotary cutting/creasing pattern is continuous, there are no gaps.
  • the repeat of the rotary tools matches the print repeat.
  • the Figures differ only in the circumference of the cylinders.
  • the peripheries of the rotary tools move at the same speed as the web substrate, that is, there is a one-to-one speed ratio between the two.
  • the rotary cutting/creasing patterns may be integrally formed on the base cylinders, in the case shown, a matching pair of complementary full wrap flexible sheet dies 2 is attached to a pair of base cylinders 1 .
  • the flexible dies and solid bases have the same repeat.
  • Figure 1a depicts the entrance of a continuous web 3 into the rotary die section, which is separated from the prior print section of the printing machine by a rotary nipping arrangement comprised of a draw roll 4 and impinging nip roll 5.
  • This nipping format attempts to isolate the tension zone of the printing section from the lower tension zone existing in the die cutter section. There must be a tension reduction in the web in the die cutter section due to the fact that the web has been partially cut across its transverse direction, thus reducing the cross sectional area of web available to carry the longitudinal tensile load in the web. If the tension in the web was not lowered in the die cutter section, one or both of two events would occur:
  • Figures 2A and 2B each show a schematic side elevational view of the proposed rotary die cutter with fixed diameter bases.
  • the rotary cutting/creasing pattern is contained in a flexible steel sheet and is continuous, however, a gap separates the leading and trailing edges of the pattern.
  • the repeat of the flexible rotary dies 2 matches the print repeat, but the repeat of the rotary base rollers 1 does not.
  • the print repeat is the same as in Figure 1a, namely, 'x', however, the repeat of the rotary base is a constant, in this case. '3x'.
  • the print repeat is '2x', but the rotary base repeat remains '3x'.
  • the rotary base repeat will always be longer than the longest print repeat of the press.
  • the peripheries of the rotary tools move at a higher speed than the average speed of the web 3 as it exits the injector mechanism 6.
  • the ratio between the die cutter peripheral speed and the web speed in the print section of the press is proportional to the ratio of the rotary base repeat-to-print repeat.
  • Figures 2a and 2b also show a web indexing mechanism 7, which is an invention previously developed by the applicant.
  • the flexible dies used in the Figure 2a and 2b arrangements may have a physical length that is anywhere in the range between the print repeat and the rotary base repeat. What is significant is that the relief pattern on the sheet die that performs the cutting and creasing always equals the print repeat found on the web and is thus always shorter than the base repeat. Non-relief areas along the length the sheet dies are manufactured to a lower elevation so as to allow the existence of a peripheral radial gap between the trailing and leading edges of the cutting/creasing pattern areas.
  • FIG 3 is a schematic side elevational view of the injector mechanism 6 that is used with all embodiments of the invention.
  • This mechanism is analogous to the applicant's previous invention as described U.S, patent 5,762,254.
  • the applicant's patent describes a device used to convert a continuous web from intermittent motion to constant motion.
  • the injector 6 is essentially an inversion of this, whereby a continuous web moving at constant speed is manipulated through a defined cycle such that the velocity profile of the web upon exit from the injector 6 enables the web to be positioned to correctly engage with a rotary die cutter operating with a fixed diameter base.
  • One cycle of the injector matches one complete cycle of the rotary die cutter.
  • Figure 3 illustrates the main elements of the injector.
  • Guide rails 9 are fixed with respect to a stationary injector frame 24, which in turn is fixed with respect to the rotary die-cutting mechanism into which the web is proceeding with a reciprocating motion.
  • a carriage 10 is mounted on the guide rails for reciprocating movement therealong, with respect to the injector frame 24.
  • First and second adjacent idler rollers 11 and 12 are mounted for free rotation on the injector frame 24, and specifically they are located at the rightward extremity thereof.
  • a third idler roller 8 is also mounted for free rotation on the carriage 10, but is spaced leftwardly away from the two adjacent idler rollers 11 and 12, as can be seen clearly in the drawing.
  • a driven roller 13 as mounted for rotation about an axis which is fixed with respect to the injector frame, and is located with respect to the third idler roller 8 such that a web, when strung between the first and second idler roller 11 and 12, thence around the driven roller 13, thence around third idler roller 8, assumes a quasi-boustrophedonic configuration, such that a portion of the web can be taken up between the third idler roller 8 and the driven roller 13 when the carriage 10 moves in a direction which increases the distance between the third idler roller 8 and the driven roller 13 (i.e. moves to the right as pictured in the drawing).
  • the length of web taken up is equal to the decrease in length of web simultaneously paid out from the injector mechanism.
  • the third idler roller 8 moves to the right while the driven roller 13 remains stationary, it will be seen that the web 3 will extend rightwardly to meet: the top periphery of the third idler roller 8, will encircle the third idler roller 8 half way, then will extend leftwardly to the top of the driven roller 13. If the two resulting reaches of the web are parallel, then a true boustrophedonic configuration would result. However, the aim of the present invention would be achieved, even if the two reaches of the web were not exactly parallel.
  • An upper endless belt 22 and a lower endless belt 23 are arranged to pass in juxtaposed relation between the first and second idler rollers 11 and 12, thence leftwardly toward the driven roller 13, thence around the driven roller 13, thence to and around the third idler roller 8, thence along different respective return paths to the first and second idler rollers 11 and 12. More particularly both the upper belt 22 and the lower belt 23 pass in juxtaposition from the top of the third idler roller 8 to the space between a fourth idler roller 20 and a fifth idler roller 21, the rollers 20 and 21 being juxtaposed at close spacing, but not providing a nip. Upon passing through the idler rollers 20 and 21, the upper and lower belts 22 and 23 separate and follow distinct paths back to the idler rollers 11 and 12, respectively.
  • the upper belt 22 partly encircles the fourth idler roller 20, thence around two further idler rollers 18 and 17, from where it extends to contact the first idler roller 11.
  • the lower endless belt upon exiting leftwardly between the fourth and fifth idler rollers 20 and 21, partly encircles the fifth idler roller 21, thence passes around further idler rollers 15 and 14, and finally to the second idler roller 12.
  • the idler rollers 17 and 18 are mounted on a web guide 19, which indepedently laterally locates the upper belt.
  • the idler rollers 14 and 15 are mounted on a web guide 16, which laterally locates the lower belt 23.
  • Translating motion in the carriage 10 is provided by a linear servo attached between the carriage 10 and the injector frame 24.
  • the carriage can receive its translating motion from a servo-driven mechanical motion generator, which does not form part of the present invention.
  • the roller 13 is preferably driven from a rotary servo motor located in the injector frame 24, this servo motor being always slaved to the motion of the printing section of the machine, thus following the line speed of the machine.
  • Various registration controls can modify the servo drive to the roller 13, thus permitting die speed of the belts to be slowed relative to the main line (web) speed. This trimming action compensates for various anomalies in web properties, such as tension variations caused from processing of the web in the print section of the machine.
  • the fourth and fifth idler rollers 20 and 21 are preferably geared together, which tends to promote synchronization of belt speeds.
  • idler rollers 11 and 12 may be geared together.
  • the belts 22 and 23 be of relatively thin section, ideally in the region of about 31 thousandths of an inch. Also, it is preferred that the coefficient of friction of the belt surfaces in contact with the web be significantly lower than the coefficient of friction of the web surface.
  • the main function of the injector mechanism shown is to convert the movement of the web from continuous to modified motion
  • the web is drawn into the entry section between the stationary idler rollers 11 and 12 with constant motion, and the action of the belts 22 and 23 acting around the translating idlers 8, 20 and 21, results in the web exiting at a non-constant, but controlled speed relative to the frame 24.
  • the carriage movement is controlled by the program driving the linear servo motor.
  • This program can be readily altered to allow a wide range of web velocity profiles for the web exiting the injector.
  • the translating action of the exit idlers 20 & 21 is such as to offer the exiting web into the rotary cutter with as small a bridging gap as possible.
  • Web guidance means such as a throat or rotating brushes can be used to support the exiting web as it makes its way between the translating idlers 20/21 and the nip point formed by the mating flexible plates 2.
  • Figures 4a to 4f show a web injection sequence in the machine beginning at the completion of the rotary die cutting cycle.
  • Diagrams 4a through 4f depict the relationship between web, injector and rotary tool position at various points in the completion of one repeat cycle.
  • Motion generating means moves the carriage such that a) when the base rollers are at the position representing the beginning of the first arc, the die cutting plates have completed a previous operation and the trailing edges of said first portions of the die cutting plates coincide with the nip between the base rollers and also with a repeat length boundary of the web, b) while the base rollers rotate through the first arc the web decelerates to a standstill, c) while the base rollers rotate through the second arc the web accelerates in the reverse direction and retracts from between the base rollers, d) while the base rollers rotate through the third arc the web decelerates in the reverse direction and reaches a further standstill, e) while the base rollers rotate through the fourth arc the web resumes forward motion toward the base rollers, and
  • Figures 5a to 5c illustrate an embodiment of the invention utilizing an injector mechanism 6 as described in Figure 3, followed by a fixed diameter base rotary die cutter 30 as described in Figure 2, followed by an enveloping belt out feed device 7 as per patent 5,762,254, lastly followed by a state-of-the-art repeat diameter base rotary pin stripper and parts delivery section.
  • Description of the operation of the pin stripper and delivery section can be found in U.S. Patent Application S.N. 08/946,577, filed on October 7, 1997, entitled "Method and Apparatus for Removing Waste Windows from Web Canon Material".
  • continuous web 3 from the print section of the machine enters the injector mechanism in which its continuous motion is convened into a variable motion such that the position of the printed images on the web 3 are synchronized with the cutting and creasing action of the fixed diameter base rotary die cutter 30.
  • the cut/creased web Upon exit from the rotary die cutter 30, the cut/creased web enters an enveloping belt outfeed assembly 7 in which the reciprocating motion of the web is converted back into constant velocity motion.
  • the web 3 Upon exiting outfeed assembly 7 with constant velocity, the web 3 then enters a repeat diameter base rotary pin stripper 31, the repeat of which is equal to the printed image repeat. Scrap parts 32 which are interior to each part are removed from the web by the stripper 31.
  • the web 3 then passes through a set of driven delivery nips 35 and 36 which act to separate the carton parts 34 from the web matrix 33.
  • the parts 34 may be retained in the web matrix 33 via a heavier nicking pattern and rewound unseparated into a roll 43 for subsequent processing.
