Definitions

  • the present invention concerns a cartridge for a heat-sensitive material tape for use on a thermal printer, particularly for printing labels.
  • Thermal printers of the above type use a heat-sensitive material tape, consisting of a plastic film with a coating of waxy ink which, following localized heating by a special thermal head, is transferred onto the material to be printed, generally a paper web.
  • the heat-sensitive material tape and the paper web are loaded into the machine as rolls, passed over a series of guide and/or tension rollers, and then rewound on respective rewinding rollers, the path of the tape and web being such that both pass between the thermal head and the corresponding print roller.
  • cartridges of heat-sensitive material to fit onto a thermal printer have already been proposed, they solve the problems described only in part, since they are laborious to mount and to fix.
  • these cartridges are of the disposable type, thus further raising the cost of the heat-sensitive material tape, which is already high.
  • the aim of the invention is to eliminate the above problems by proposing a cartridge for heat-sensitive material tapes, character­ized in that it has a reusable support.
  • the cartridge consists of two asymmetric side plates connected to each other by shafts forming guide rollers for the tape, whereas the roller on which the heat-sensitive material tape is fitted and the rewinding roller are mounted to project from the inside plate of the cartridge.
  • FIG. 3 part of a thermal printer is shown, designated as a whole by reference number 1, of the type using a heat-sensitive material tape for printing on a paper web not shown.
  • the printer 1 comprises a base 2 and a supporting side panel 3, on which projecting shafts are mounted to feed and guide the heat-sensi­tive material tape and the paper web.
  • the paper web to be printed is loaded as a roll, passes over guides not shown, and is fed between a thermal head 4, indicated by the dashed and dotted line in Figure 3, and a print roller 5, normally motor-driven, then rewound onto a rewinding roller 6, also motor-driven.
  • the head 4 pivots around a hollow spindle 7 and can be raised from the roller 5 by means disposed on the rear of the side panel 3.
  • the hollow spindle 7, together with another spindle 8 provided on the front of the side panel 3, also serves as a guide for insertion of the cartridge according to the invention, which will now be described.
  • the cartridge for the heat-sensitive material tape indicated as a whole by reference number 9, comprises two asymmetric side plates 10 and 11, connected to each other by spindles 12, 13, 14 and 15 and by a chanfered front wall 16, forming guides for the heat-sensitive material tape, indicated by reference number 17, which is loaded as a roll onto a roller 18 projecting from the inside wall 10, and rewound onto a rewinding roller 19, also projecting from the wall 10.
  • the outer side plate 11 is lower than the inner plate 10, so as to permit axial insertion on the roller 18 and removal from the roller 19 of rolls of heat-sensitive material 17.
  • the guide roller 15 provided in the front part of the cartridge 9 has an internal through hole 20, so that it can accommodate the spindle 8 mounted on the side 3 of the machine.
  • a spindle 21 is also mounted, projecting and facing towards the opposite plate 10, designed to be accommodated in the hollow spindle 7 mounted on the side 3 of the printer.
  • a window 22 is provided in the inner plate 10 of the cartridge 9 through which the hollow spindle 7 and the whole head assembly 4, shown by broken lines in Figure 3, can pass.
  • Mounting of the cartridge 9 on the printer 1 is achieved by aligning spindles 15 and 21 respectively with spindles 8 and 7 and pushing the cartridge so that the spindles 8 and 21 enter spindles 15 and 7 respectively.
  • a central shaft 23 of the rewinding roller 19 protruding from the inner wall 10 of the cartridge, fits into a motor-driven floating coupling 24, provided in the side 3 of the printer.
  • the coupling 24 is designed to be floating to simplify insertion of the shaft 23 and to compensate for any slight shifts out of axis of the latter.
  • the cartridge is fixed by means of a small bracket 25 that can be brought to engage with a circular groove 26 of a pin 27 fixed to the side 3 of the machine.
  • the bracket 25 is pivoted to the guide spindle 14 and can be turned through about 90° by means of a knob 28, the threaded shank of which passes through a slot 30 with a circular section made in the outer plate 11 of the cartridge 9 and screws into the outer arm 31 of the bracket 25.
  • the bracket 25 is shown in the cartridge locking position. In this position the bracket 25 also serves to stretch the tape 17, particularly the section of tape between the bracket and the chamfered wall 16, which falls between the head 4 and the print roller 5.
  • it is sufficient to loosen the knob 28 and slide it into the highest part of the slot 30, so that the bracket 25 is disengaged from the groove 26 of the pin 27, and at the same time the band 17 is slackened.
  • Means are also provided for locking the loading roller 18 of the roll of heat-sensitive material 17 when the cartridge is not mounted on the machine.
  • These means consist of a cogged pinion 32 provided at the base of the loading roller 18, which is engaged and thus locked by a tooth 33 of a pawl 34 which crosses the inner plate 10 of the cartridge and can move only axially against a return spring 35.
  • the pawl 34 comes to rest against the side 3, compressing the spring 35 and moving away the tooth 33 of the pinion 32.
