Definitions

  • the invention relates to an arrangement for exchanging ink-printing modules or ink-jet cartridges in a printing device, in particular in a franking and / or addressing machine. It has been proven to exploit the advantages of ink printing also in the field of mechanical franking and / or addressing. The printing takes place without contact by means of ink print head, see for example DE 44 24 771 C1 and EP 0 696 509 B1 ,
  • the inkjet print head and cartridge form a single unit.
  • the ink printing module is forcibly guided locked in a shaft-shaped receiving device.
  • the ink pressure module must be replaced. This is done by pulling by hand. To do this, first disengage a locking lever, grasp the ink pressure module on a corner of the handle with two fingers, and pass the locking lever at an angle, see, for example, the HP DeskJet 1220C User Manual of 10/1999. It will depend more or less on the skill and care of the operator.
  • the printing system consists of a frame, two inkjet printing modules and a shaft-shaped receptacle with two assigned compartments each for the two.
  • Each inkjet print module consists of an inkjet print head, ink supply, chip, and contact pad.
  • the mating contacts are fixedly mounted in the receptacle.
  • the ink printing modules are arranged parallel but offset from each other to achieve the required printing gap length.
  • the receptacle is pivotally mounted about an axis which is fixed in the frame.
  • the receptacle For priming and for sealing the ink jet print head, the receptacle is pivoted so far away from the printing position into a position that the nozzle surface thereof is directed downwards is. At the same time this is the position in which a replacement of the ink pressure module is possible.
  • the printing position and the sealing position are therefore determined by clearly defined positions of the ink jet print head and the cleaning and sealing device. In addition, various cleaning areas are provided. In a cleaning area in front of the sealing position, the inkjet printing head is pivoted away from the printing position so far that the nozzle area is arranged in the engagement area of the wiper lips of the cleaning and sealing device.
  • the wiper lips strip over both the nozzle surface and along two side edges, resulting in the latter to Tintenrestablagerungen.
  • these deposits can contaminate the mating contacts and consequently jeopardize the reliability of the printing device. This effect is exacerbated when the printing device is provided with an additional ink supply system, since in this case significantly more wiping and thus larger deposits incurred.
  • Another problem is that when pulling or plugging the inkjet printing module, the mentioned edge in the worst case along the mating contacts along and this can be damaged.
  • Purpose of the invention is to improve the reliability and prolong the life of the printing device with minimal effort.
  • the invention has for its object to provide a device for uncomplicated replacement of an inkjet printing module in a printing device of the type described above, which makes do with little technical effort and is also suitable for franking and / or addressing machine. In particular, contamination and mechanical impairment of the mating contacts for the ink pressure module should be prevented.
  • a service flap 10 is provided, which extends into the region of the guide plate 101 for the print carrier.
  • the service flap 10 is shown in the open state, so that the receptacle 12 with the two printing modules 11 is visible.
  • the printing modules 11 are completely inserted and fixed in each case by means of an associated bolt 121.
  • the cover 102 serves to prevent unauthorized access to the postage meter.
  • the space underneath can be used for additional ink tanks.
  • a receptacle 12 with two locked printing modules 11 is shown.
  • the receptacle 12 consists of two side walls 122, 123 and a common double-angle-shaped carrier 126, whose integral part is a center wall 120.
  • the side walls 122, 123 are made the same, so that the further description can be limited to the right side wall 123.
  • the latch 121 is about an axis 1231, see Fig. 4 Detail B, pivotable, for which in the side wall 123 a bore 1233 is provided.
  • Another bore 1232 serves as a guide hole for a pivot 1611, see also Fig. 4 and 5 .
  • the side wall 123 is releasably secured to the carrier 126 by means of two fastening screws 1230.
  • the latch 121 is rotatably mounted in the left chamber about an axis 1221, for in the Middle wall 120 has a bore 1202 and in the left side wall 122 a bore 1223 are provided. The attachment is made by means of screws 1220.
  • the contact pad 112 in the form of two angles, which are arranged mirror-symmetrically spaced .
  • a locking lug 115 is formed in a known manner, which is adapted to the contour of the bolt 121.
  • an unspecified grip part is provided in the front shell. Above the contact field 112 of the module chip 114 is arranged.
  • Fig. 4 is the right side wall 123 removed, the latch 121 for the right print module 11 is folded up and taken out the same.
  • the molded shoulder 1212 can be seen as a counterpart to the locking lug 115, see also Fig. 3 ,
  • the latch 121 for the left pressure module 11 is closed.
  • the bolt 121 is designed in a known manner as a two-armed lever which is rotatably mounted about an axis 1231, see detail B.
  • the longer, front lever arm is designed as a handle part.
  • the outer contour of the shorter, rear lever arm serves as a leading edge 1211 for a fork-shaped rocker 16.
  • the rocker 16 is pivotally mounted with its longitudinal legs 161 in adapted recesses of the side walls 122, 123 and the middle wall 120 about a molded pivot 1611.
  • adapted guide holes 1201 are provided in the center wall 120, 1222 in the left side wall 122 and 1232 in the right side wall 123, see also Fig. 5 .
  • the transverse leg 162 of the rocker 16 is provided with a guide nose 1621 which lies in the engagement region of the guide edge 1211 of the bolt 121.
  • the counterparts 131 are resiliently inserted into the contact area 112 of the pressure module 11 and also resiliently a counterpart 132 for contacting the module chip 114 of the pressure module 11, see also Fig. 5 .
  • the carrier rear wall 1265 has a vertically fixed web 12651, which serves as a stop for the printing module 11, in particular the non-contact portion of the contact pad 112 in the unlocked state, see detail A. In this way it is ensured that the pressure module 11th only as can be taken from the shaft-shaped receptacle 12 or introduced into this, that unwanted contacts between the contacts of the printing module 11 and the mating contacts 131, 132 are reliably prevented. The contacting takes place only when the bolt 121 is closed.
  • Fig. 5 Further details of the receptacle 12, the board 13, a closure plate 14, a spring pressure piece 15 and the rocker 16 are shown.
  • the assembly of the rocker 16 is possible only with removed side walls 122, 123, also the bolt 121.
  • the board 13 is inserted into the support rear wall 1265 in adapted recesses, see also Fig. 6 and 7 ,
  • a spring pressure member 15 with a prestressed compression spring which is fixed on the one hand in the circuit board 13 and on the other hand in the closure plate 14.
  • the spring pressure piece 15 is dimensioned so that a sufficient contact force is secured.
  • the compression spring 12652 is arranged between the closure plate 14 and transverse leg 162 of the rocker 16 and protrudes through a through bore 12653 in the support rear wall 1265.
  • the compression spring 12652 is used for resetting or pivoting back the circuit board 13.
  • the fulcrum lies in a matched recess of the support rear wall 1265, see also Fig. 6 Detail B as well Fig. 7 ,
  • the upper edge of the board 13 is applied to a correspondingly shaped - rounded - supporting web 12654.
  • the dimensioning of the rocker 16 together with associated compression spring 12652 is chosen so that the counterforce is greater than the contacting force.
  • Fig. 6 the conditions are shown with dissolved latch 121 and partially drawn pressure module 11.
  • the board 13 is under the Spring action of the compression spring 12652 pivoted back to the rocker 16.
  • Fig. 7 the conditions are shown with fully inserted pressure module 11 and pressed latch 121.
  • the circuit board 13 is flat against the associated areas of the carrier rear wall 1265.
