Definitions

  • the present invention relates to a method and an assembly for the feeding of a printing machine, and particularly a laser printer, with single sheets from a plurality of separate reels of paper of the so-called micropunched tipe, namely of the type in which the paper web forming the reels is liable of a localized separation by means of weakened portions obtained by micropunching.
  • the method and assembly of the present invention consisting in the use of a number of paper reels at least equal to the maximum number of form colors which must be used, of a number of guide members for the paper webs equal to the number of paper reels, of a number of tearing devices still equal to the numer of reels, of a like number of conveying trays and of only one laser printer using single sheets.
  • the aforesaid method is carried out by means of an assembly comprising a predetermined number of paper reels, each housed in a corresponding unwinding device, a like number of web diverters having the purpose of guiding each paper web from its reel to a corresponding tearing device, a like number of tearing devices each associated to a corresponding paper web, and a like number of conveying trays each connected between each tearing device and only one laser printer for the whole assembly.
  • the unwinding devices used in the assembly of the invention are belt unwinding devices and likewise particularly the web diverters are diverters comprising roller pairs by which the paper web is bent and passed from the laying position of the reel unwinding devices to that of the tearing devices.
  • the tearing devices are mounted one above the other so as to form a sort of column supported by a supporting and fastening framework.
  • each tearing device is connected with the only one inlet of the single sheets of the laser printer by means of a proper conveying tray located between each tearing device and the printer.
  • the printer, the paper reels and the tearing devices are all under the control of a same central unit by which the paper to be sent to the printer is selected, and consequently the corresponding unwinding devices and the tearing devices are actuated.
  • a laser printer 10 is positioned so as to receive single sheets 12 which are separated by means of tearing devices in an assembly 14 comprising separate tearing devices 141, 142....,14 n and transferred by means of conveying trays 161, 162,....,16 n , to a paper inlet of the laser printer 10, said single sheets being obtained by separation effected by means of the tearing devices 141, 142,...,14 n , from paper webs 181, 182,...18 n , each coming, through web diverters 201, 202,...,20 n ,by which the webs are guided according to the respective arrows 211,212,....,21 n , from a respective paper reel 221,222,....,22 n , abutting onto a respective unwinding device 241, 242,....,24 n .
  • the tearing devices 141,142,....,14 n can be either of the tearing devices disclosed and claimed in the Italian applications for utility model patent Nos.22177 B/88, 21876 B/90 and MI91000262 respectively filed on November 21, 1988, October 3, 1990 and March 27, 1991, in the name of the same Applicant as the present application.
  • the unwinding devices 241, 242,....,24 n can be either of the devices described and claimed in the Italian patent application No.19532 A/89 filed on February 22, 1989, and in the application for utility model patent No.MI91U000343 filed on April 30, 1991, in the name of the same applicant as the present invention.
  • the web diverters 201,202,....,20 n essentially consist of idle cylindrical rollers 301,302,...,30 n and 321,322,....,32 n , by which the respective paper webs 181,182,....,18 n are deviated from their positions in which are sidewise located with respect to the related reels 221,222,....,22 n to the vertically superimposed positions related to the tearing devices 141,142,....,14 n , said rollers being suitably connected to each other by some sort of proper structure such as the upright 34 shown in fig.2.
  • the tearing devices 141,142,....,14 n are mounted onto a supporting member, consisting of uprights 36 in turn supported by a basement 38 which can be fastened to the floor, by which the same tearing devices are maintained in a fixed vertical alignment.
  • the lowest tearing device 141 is directly connected to the laser printer 10 by means of a conveying tray 161 which, being provided with small rollers 40a-c and with small belts 42 movable according to the arrows 44a,44b, causes the single sheets 12 coming from the tearing device 141 to be directly inserted into the inlet 46 of the laser printer 10.
  • next tearing devices 142,143,...,14 n are provided with simple conveying trays 162,163,....16 n of progressively reduced lengths by which the single sheets coming from the upper tearing devices are caused to fall onto lower and lower trays until the lowest tray is reached from which the same sheets are fed to the inlet 46 of the printer 10.
  • a central control processing unit 50 is connected through a multiple line 52 to the printer 10 for the exchange of information and control signals by which the number and type (for example the color) of the sheets to be fed as well as the time at which each single sheet must reach the printer are determined.
  • the connections 541,542,....,54 n to the related tearing devices 141,142,...,14 n and the connections 561,562,....,56 n to the related unwinding devices 241,242,....,24 n the connections being active to fed proper control signals to the interested tearing devices and unwinding devices.
  • the operation of the assemply of the invention is as follows:
  • the sequence of sheets to be printed by the printer 10 is set at the control central unit 50, for example by means of the keyboard 58, it being possible to display said sequence onto the display 60.
  • the central control unit 50 decides, on the basis of the information coming from the printer 10, what sheets are to be selected and thus the single tearing devices 161,162,....,16 n as well as the unwinding devices 241,242,....,24 n , are actuated, whereby the forming of any desired file is permitted.
  • the instructions instead of being entered through the keyboard 58, might be fed through devices for the reading of magnetic tapes, magnetic or optical disks or the like.
  • the tearing devices might be positioned sidewise to each other, whereby the conveying members from the tearing devices to the printer would be modified and the web diverters would be no longer necessary.
