Definitions

  • the actual average operational speed of a high-speed printer as it is supplied by the manufacturer is about 50% of the printing speed thereof.
  • the novelty of the invention is the base of the operation thereof which in its apparent simpleness involves both an extreme rationalization of the functions and the application of completely original solutions,such as the cutting of the adhesive tape joining two adjacent packages which is carried out without using a counterblade.
  • the invention is also provided with a device which maintains the package being supplied to the high-speed printer in the optimal position, by moving the whole series of packages as they are used, and also calls the operator for refilling during the time required for the consumption of the last package.
  • the operator of course, each time stores the number of the packages forming the series he has composed in the unit memory.
  • the invention i: also original in that the pins for placing the paper in position on the joining plane are completely retractile, thus allowing three different aims to be reached and accordingly: using very precise reference pins in the paper transport holes for the positioning of the paper and the successive joining operation; completely releasing the paper web from the pins after the joining operation; and, making the joining plane completely free from any projections which could "hook” the paper coming out from below the joined paper web.
  • Joining plane 5 supported by column 6 which is secured to carriage 7 moving on guides 8 and anchored to body 1 through brackets 9, can move along the whole package backing plane of the unit.
  • Joining plane 5 is also able to move in and out of the working area (full and dotted lines in Figure 1A) through guiding rods 10 which are anchored to plane 5 and can slide within supports 11 rigidly secured to column 6.
  • End members 12 and 13 of the service unit substantially have the function of defining backing plane 2, even if the control unit of the apparatus 14 and an assembly of arms and rollers have been placed on ends 12 and 13, respectively, in order to optimize the removal of the paper from the package arranged to be supplied to the printer.
  • FIG 3 is an exploded view of the adhesive tape cutting assembly which allows the cutting operation to be carried out without using counter blades.
  • the main member for this operation is cutting blade 23 which comprises a heatable element such as a suitable electric resistance 23A which is heated by the Jaule effect on the cutting operation.
  • the resistance is rigidly connected to blade body 23B by through holes 23C and weldings 23D between the resistance and electric paths 23E, thus forming a monolithic component which allows the cutting of the adhesive tape to be easily carried out as it is heated and approached to the adhesive tape through raising pin 24 operated by piston 25.
  • the cutting is controlled by an operator, while tne heating time and the to-and-fro movement time, which are extremely short and almost instantaneous, are controlled by a microprocessor.
  • Figure 3 also shows a conventional cutting blade 26 which, to minimize the forces acting on the cutting to an acceptable value, has been cusp shaped with a central tip protruding for the cutting engagement. Also in this case, the adhesion force of the adhesive tape' on counterguide 28 after the joining operation is sufficient to assure the tape cutting, provided the tape is of a suitable type.
  • the adhesive tape cutting assembly comprising blade 23 also comprises a holding guide for blade 23 including members 27 and 28 connected to eech other by a screw 29. When these members are tightened a space 27A intended to receive resistance 23A is formed on member 27. The vertical movement of the blade is formed by opening 23F provided on the blade.
  • the body of guiding carriage 27 is secured to joining plane 33 by tightening plate 32 through screw 30.
  • This device allows the distance between the holes for placing in position the paper to be joined and the outer edge of the sheet where the adhesive tape is cut to be adjusted by sliding all the cutting carriage with respect to support 33. It should be noted that these adjustments are extremely reduced since the distances are standardized and can vary only from one supply of paper support to the other.
  • Cover 28 which is made from an electrically insulating material, is at the same top level of plane 33 when it is placed in the seat therefor.
  • a further feature of this device is that blade 23 can be replaced by simply untightening screw 29 and removing cover 28, thus allowing the paper-blade adjustment to remain unchanged.
  • a housing In the body of the joining plane a housing is formed intended to receive cross-shaped carriage 43 and capable of sliding thereon in order to adjust the width of the paper to be joined.
  • This carriage is moved through screws 44 which are rigidly screwed in body 40 and can be operated by handles 45. Screws 44 engage the carriage through lead nuts 46.
  • the retractile pins for positioning and blocking the paper on the joining plane are applied on the plane body on one side and on moving support 43 on the other side.
  • the embodiment of the assembly, the components and the transport means are identical for both sides and, accordingly, Figure 4A shows a sectional view of the moving side.
  • this assembly comprises four "combs", each comprising a plurality of pins 49 having a suitable diameter and shape allowing them to easily engage with a sufficient grip the transport holes of the paper support.
  • These pins are connected to a base plate 50 through elastic sealing rings, thus obtaining a non rigid connection and avoiding the need of identical center distances for allowing the pins to slide in the guiding holes formed on plane body 40 and cross-shaped support 43.
  • These paper support positioning and blocking pins are normally held in the retracted position by members 51 and, in this case, pneumatic piston 52 is a stop member. Pistons 52 are controlled in order to cause pins 49 to come out of the upper side of the joining plane: Thus, these pins are used to place and maintain in position the paper support to be joined. The number of the pins is higher at the center and outer sides of the plane, thus allowing the paper to exert a better grip thereon. Similar solutions aiming at the same results have not been described since they are equivalent.
  • Adhesive tape roll 55 is connected to the joining plane by a bracket 54 and the tape support 56 is held in place by a snap removable cover 58.
  • Figure 4C shows the 90° tape transmission which drives adhesive tape 58 from roll 55 to guiding wheels 59 and 60 through stationary pin 57.
  • the mounting of the tape on support 56 is such that the tape side sliding on pin 57 is the non adhesive side, while the adhesive side of the tape rests on cylinders 59 and 60.
  • Cylinders 59 and 60 are supported by members 62 and 61, respectively.
  • Supports 61 have the shape of a chute facing the inner portion of the plane and, accordingly, they also facilitate the coming out of the plane after the joining operation and the engagement of the adhesive tape with cylinder 60.
  • Figure 4B shows the moving side only, since the other side is identical.
  • Figure 4B clearly shows cutting blade 23, main support 27, operating pin 24 driven by piston 25 which is supported by a bracket 48.
  • Figure 4B also shows a blocking screw 30 which is intended to adjust the distance between the positioning pins and the edge of the cutting blades shown also in Figure 4.
  • FIGS 5A-5E show the steps of the joining of two adjacent packages. These steps comprise:
  • references 64 and 67 the paper packages to be joined are referred to by references 64 and 67 and they are placed on package backing plane 2.
  • Reference 64 refers to the forward package and sheet or form 65 is the last sheet of this package.
  • joining plane 5 is conveniently placed between the two packages to facilitate the operation, the positioning and blocking pins being "out", as indicated by reference 49.
  • Sheet 65 is placed in position on the joining plane by fitting these pins in the paper transport holes and causing the end edge of the sheet to coincide with the central line of the plane referred to by reference 70.
  • Figure 5A also shows the steps intended to facilitate the joining operation and accordingly, placing sheet 65 with the end edge thereof at the center of the plane and causing the pins to fit inwardly with respect to the plane, either lowering the sheet or letting it down as shown by arrow 71. On this operation the fitting of the positioning and blocking pins should be manually helped. The same operation should be carried out with the first sheet or form 68 of package 67 in a specular way with respect to the central line of plane 5, as shown by arrow 72.
  • tape joining sheets 65 and 68 is of a special type having a central punching, available on the market from specialized manufacturers. Thus, this tape is not an obstacle either to the folding of the joined sheets or to the tear separation thereof following the processing operation.
  • the tape is then lowered onto guiding cylinder 60, thus reaching position 74 shown in full line and being centered with respect to the central line of the plane and exactly between two adjacent sheets 65 and 68. This operation is facilitated by the engagement of supports 61 and the shape of receiving cylinder -60. As mentioned above, the tape remains suitably tensioned between guiding cylinders 59 and 60, the adhesive side thereof facing towards the plane.
  • Figures 6A-6C show a conventional cycle of complete rifilling of the unit during the normal use thereof.
  • Figure 6A shows the step of calling of the unit to the operator, which calling can be carried out either with a sound or a light signal. As mentioned above, this step lasts all the time required to process the last package being supplied to the printer, unless the operator intervenes.
  • Figure 6B shows an intermediate filling step, when the operator has already placed in position all the sheet packages and continuously connected the first three packages.
  • Figure 6C shows the unit at the end of the operation; as shown, it has been considered that the printer has continued to be supplied. At the end of this operation the operator has to store the total number of the packages present on the plane in the microprocessor memory.
  • this invention allows an extremely compact version of the unit to be carried out, having such a size as to receive two packages only. This feature is quite important, considering that the space available does not always correspond to the space required.
