Definitions

  • the invention relates to a cartridge for a print head of an ink writing device in a typewriter of the type specified in the preamble of claim 1.
  • the write head can have two rows of nozzle outlet openings arranged in parallel in the direction of the matrix columns, the nozzle outlet openings of one being arranged offset from those of the other row. Only ink droplets are selectively ejected from the nozzle outlet openings of the one row to produce quick writing, while ink droplets are thrown out from the nozzle outlet openings of both rows to produce fine writing. Since different printer controls are also required for this, changing the write head with the appropriate code marks is very appropriate. These code marks interact automatically with a decoding circuit in the machine when the writing mechanism is changed. This prevents incorrect operation by the user.
  • DE-AS 21 42 409 provides for a replacement of the print head in inkjet printers if the inside of the write head is contaminated or one of the outlet openings is blocked.
  • the write head can be coupled to a slide that can be moved along the record carrier via an electrical and mechanical connection. There a Replacing the print head in any slide position is possible and the outlet nozzles are also not protected from contamination, clogging and thus failure of nozzle outlet openings is very easy.
  • the invention has for its object to provide a cartridge for a print head of an ink writer in typewriters, which allows easy replacement of the print head without subsequent disruptions in printing and makes incorrect operation on the part of the person operating the machine impossible.
  • This object is achieved by the invention characterized in claim 1.
  • the cassette according to the invention enables simple and safe handling for changing the write head, the write head being exchangeable only when the carrier carriage is in the rest position and is always protected against contamination when removed from the carriage.
  • FIG. 1 shows a cassette 15 for a write head 17 of an ink writing device in a typewriter, the write head 17 consisting of an ink mosaic print head 19 with outlet nozzles 21 and an intermediate ink container 23 firmly connected to it, and with the movable carriage 7 via an electrical one when plugged on and mechanical connections producing plug connection can be coupled.
  • the write head 17 has means for additionally automatically establishing a plug connection to an ink supply line when it is plugged on.
  • the cassette 15 consists of a housing 29 which can be inserted and locked into a receiving device 25 on a side wall 27 of the machine and in which the write head is arranged in a protected manner in and outside the receiving device 25 in the non-operating position.
  • On the print head 17 and the Ge Housing 29 are arranged holding means by means of which the write head 17 can be securely stored in a position disassembled from the carriage 7 in the housing 29 and in the assembled state of the housing 29 on holding members of the receiving device 25 and the writing head 17 on holding members of the carriage 7.
  • the housing 29 of the cartridge 15 has an opening 31 for retracting and extending the carriage 7 with the write head 17.
  • guide grooves 33, 35 are arranged in the housing 29 on both sides of the opening 31, which can be positively engaged with guide webs 37, 39 fixedly arranged on the write head 17.
  • This locking member 41 is a locking lever 43 with a locking lug 45, which can be locked behind a locking edge 47 on the write head 17 when the housing 29 is removed from the receiving device 25.
  • the locking lever 43 is rotatably mounted on the top 49 of the housing 29 in a recess 52 of a bearing block 54 about an axis 51 and can be acted upon by a spring 53 such that the locking lug 49 through an opening 55 in the housing 29 in front of the latching edge 47 of the writing head 17 can be brought.
  • the write head 17 is positively locked in the housing 29 such that the write head 17 and the housing 29 form an independent transport unit.
  • the locking lever 43 protrudes with its free end 57 beyond the side wall 27, such that an intermediate lever 61, which is pivotably (59) mounted on the receiving device 25 in two end positions, brings the locking lever 43 into and out of its locked position via a stop lug 62.
  • the recess 52 in the bearing block 54 and the locking lever 43 are designed such that the locking lever 43 can only be adjusted with a special tool for releasing the write head 17 when the cassette 15 is removed from the receiving device 25. This prevents the person operating the machine from separating the housing 29 and the write head 17 from one another as desired. This separation should only be possible by a customer service specialist.
  • the intermediate lever 61 can be pivoted about an axis 59 and, when the cassette 15 is inserted, bears against a stop 63 fixed to the frame. In this position according to FIG. 1, the locking nose 45 is out of engagement with the locking edge 47 on the write head 17, so that the carriage 7 can be retracted from its rest position in the housing at any time for a printing operation and after each printing operation. If the print head 17 is to be changed, the intermediate lever 61 must be pivoted downward against the force of the spring 63 to such an extent that the locking lever 43 is released through the opening 55 in order to engage the locking lug 45.
  • the pivoting of the intermediate lever 61 takes place via a manually operable control lever 65 which is pivotally mounted on the side wall 27 about an axis 67 in two end positions.
  • the control lever 65 is pivoted clockwise against the force of a spring 69, which lifts off a stationary stop 71 fixed to the frame.
  • a stop edge 73 of the control lever 65 acts on a bent tab 75 on the intermediate lever 61 in such a way that the locking lever 43 is released for falling into the locked position.
  • the manually operable control lever 65 can be coupled via intermediate members 77 and a coupling 79 with a locking device 81 for the write head 17 to the movable carriage 7 in its inoperative position.
  • This locking device 81 has a locking shaft 83 rotatably mounted in the slide with a locking hook 85, by means of which the write head 17 with the ink mosaic print head 19 and the ink intermediate container 23 can be firmly locked onto the slide 7 via a stop 87.
  • the locking shaft 83 has a coupling half 89 with a cuboid recess 91, the side surfaces 93 of which taper towards the bottom.
  • the other coupling half 95 is rotatably mounted in the frame and has a cuboid shape corresponding to the recess 91 trained driving pin 97.
  • the fixedly mounted coupling half 95 is connected to the control lever 65 via a transmission gear.
  • the driving pin 97 is firmly connected to a gear 101, which is in positive engagement with a toothing 99 on the control lever 65.
  • the two coupling halves 89, 95 and thus the locking shaft 83 can also be pivoted such that the locking hook 85 comes into and out of engagement with the stop 87 on the intermediate ink container 23.
  • a second hook can also be used instead of a locking hook 85 in order to press the write head 17 firmly against the carriage 7.
  • an exact coupling of the electrical and ink supply connector must be guaranteed.
  • the control lever 65 can be locked in its starting position according to FIG. 2 by a locking lever 103.
  • This locking lever 103 is pivotally mounted about an axis 105 in the frame, is provided with a locking arm 107 for the control lever 65 and with a stop arm 109 which is moved by the carriage 7 when it moves into the inoperative position against the force of a return spring 111 while lifting off a fixed one Stop 113 can be acted upon to release the control lever 65.
  • the locking lever 103 In each rest position of the carriage 7, the locking lever 103 is acted upon to release the control lever 65, the two coupling halves 89, 97 also always being coupled. If the write head 17 is to be replaced, then only the control lever 65 needs to be turned clockwise to the stop 115. As a result, the locking hook 85 is turned away from the stop 87 with its locking nose 86. The write head 17 can then be pulled upwards according to FIG. 2. This change takes place according to FIG. 1 with the help of the cassette 15.
  • the cassette 15 can be inserted into the receiving device 25, which has an insertion opening 117 with guides 119, 121 for guide elements 123, 125 on the housing 29.
  • the cassette 15 can be locked in the receiving device 25 by a locking lever 127 which is pivotally mounted in the frame about an axis 133 and can be pivoted in front of the insertion opening 117 by means of a locking lug 129.
  • the locking lug 129 is arranged on an arm 131 of the locking lever 127.
  • a spring 135 is articulated on the locking lever 127, which brings the locking lever 127 out of the region of the insertion opening 117 as soon as the manually operated control lever 65 is pivoted from the rest position into the release position.
  • a cover device 143 is also arranged in the housing 29 of the cartridge 15, through which the outlet nozzles 21 on the ink mosaic print head 19 can be covered. In this way, contamination of the outlet nozzles 21 and clogging thereof during the pauses in writing or also when changing the print head are reliably avoided.
  • the cover device 143 can be designed as desired and z. B. consist of a rotatably mounted and impregnated with a cleaning liquid cover roller 145.
  • encodable control means 147 can be arranged on the housing 29, which can be operatively connected to a detection device 149 in the receiving device 25 of the machine, see FIG. 3.
  • This detection device 149 sends control signals to the printer controller via a decoding circuit to generate the desired font. As a result, incorrect operation on the part of the user is no longer possible.
  • FIGS. 4, 5A and B show another embodiment of a sealing device between the carriage 7 and the intermediate ink container 23.
  • an eccentrically designed locking shaft 150 is rotated by the control lever 65 according to Figures 1 and 2 by 180 °.
  • a stop lug 155 of a locking hook 153 rotates from its stop position initially by 30 ° as far as the stop 151. Since the locking hook 153 can no longer turn, the eccentric shaft 150 which rotates 150 ° further pulls the locking hook 153 down.
  • the intermediate ink container 23 is pressed against the carriage 7 via a stop 156. This ensures a secure coupling of the electrical, mechanical and ink-carrying connecting means.
