Definitions

  • the invention relates to a modular ink jet print head of the type specified in the preamble of claim 1.
  • Such an ink jet print head composed of edge shooter ink jet modules can be used in small, fast printers. These are used, for example, for franking machines for franking mail.
  • inkjet printhead modules are constructed according to the edge shooter or face shooter principle and are detachably arranged in a holding means (First annual ink jet printing work-shop, March 26-27, 1992, Royal Sonesta Hotel, Cambridge, Massachusetts).
  • the modules are spaced apart from one another with a high tolerance because the holding means here consists of a plate with elongated openings and two fastening means for each module, the openings lying vertically or obliquely one above the other. Therefore, the time delay of the control pulses from module to module is high and has to be set differently, which means an increased effort in controlling the drivers.
  • a single module cannot be changed without the time delay for the controller having to be reprogrammed or set.
  • an ink jet printhead which is constructed from face-shooter modules which are arranged at an angle to one another and can be detachably fastened in a holding means.
  • Such inkjet printheads with an inclined arrangement of the modules to the surface of a recording medium produce a more uniform recording even when the thickness of the recording medium fluctuates.
  • the ink jet no longer strikes perpendicularly but at an angle to the recording direction.
  • a major disadvantage of the face shooter is its larger footprint, which faces the recording medium, which makes the distance between the nozzle lines of the modules large and only a few modules can be integrated in an inkjet printhead. This limits the recording density.
  • the ink supply containers are arranged separately from the printhead and the ink supply pressure has to be within the capillary pressure range, malfunctions frequently occur with ink jet printheads. If the printhead is clogged, the entire printhead must be replaced.
  • Another edge shooter ink jet module that has already been proposed consists of at least three pieces of glass, that is to say an opening middle part and two side parts each having a row of ink chambers.
  • a common row of nozzles is located on the front of the first side part.
  • the two rows of ink chambers and the associated nozzles are offset from one another, with all nozzles in one row lie on the end face of the first side part and the ink chambers of the second side part are connected via channels in the middle part to the corresponding nozzles in the first side part or to the ink feed.
  • an even more highly integrated module can be produced, which has only a single row of nozzles and at the same time forms an edge shooter ink jet in-line print head (ESIJIL print head).
  • a spacer layer consisting of the same material as the piezoelectric elements provided for driving the ink out of the ink chambers, is arranged between the respective sintered blocks of three glass parts and connects the sintered blocks to one another in a non-detachable manner. If the printhead is damaged during assembly or if the printhead becomes defective in later operation, the entire printhead must be replaced again. However, it is still difficult to achieve a high yield in the production of such printheads. So far, it has not been possible to assemble edge shooter ink jet modules into an ink jet printhead with a high recording density and with low production costs without, on the one hand, complex mechanical and electrical adjustment being necessary due to the manufacturing tolerances or, on the other hand, defects in the printed image arise.
  • Another object is that the modules can be removed individually and can be exchanged in an uncomplicated manner. It should be guaranteed that only the same module type is used correctly in the printhead and after an exchange of modules there are no defects in the printed image.
  • the invention is based on the fact that the ink jet printhead is constructed from several modules of the same type, a flat type of ink jet module consisting of several module parts and spacers being used, which ensures precise maintenance of the distance and the lateral offset between the exchangeable modules allowed.
  • the spacers are attached to the module part in a vertical position with their base surface on a reference plane, which is formed by one surface of a module part.
  • the spacers of one module are brought into contact with at least those of another module.
  • each module has a reference edge with a highly precise distance d from the first nozzle of its nozzle line.
  • a base plate located in the ink ejection direction has a common opening for the front edges of all modules.
  • offset stop edges for all modules are incorporated on one side, which is parallel to one of the second sides of the base plate.
  • the reference edges of the modules are brought into contact with an associated stop edge of the base plate, so that there is a defined lateral offset c between the modules.
  • the reference plane is that surface of a module part which lies parallel to the plane in which the nozzle channels are formed.
  • all the nozzle channels are incorporated into the inner surface of the first module part, i.e. the distance between the inner surface of the module part and the nozzle channel plane becomes minimal and goes to zero.
  • three such spacers are provided, which are located on its periphery and are fixed with their base surface standing on the inner surface of one module part, which carries the nozzle channels.
  • a compact ink jet print head which has several easily replaceable flat modules of the same structure and a U-shaped module carrier with a base plate as a positioning, holding and fastening means for the modules.
  • the base plate located in the ink ejection direction again has a common opening for the front edges of all modules, which advantageously makes it possible to produce modular ink jet print heads for a vertical arrangement of the modules on the surface of a recording medium.
  • Two legs are arranged on two first sides of the base plate.
  • Fastening elements for the modules are arranged on the two second sides of the base plate of the module carrier and adjustment means on the legs, which interact with the spacers of successive modules lying one above the other by a constant distance between the successive modules Modules.
  • Another advantage is the possible electrical monitoring of the module type via the spacers in order to guarantee that only the same module type is used correctly in the print head.
  • FIGS. 1a to 1d show a composite print head, with detachable modules 1 and with a U-shaped module carrier as the holding means.
  • the U-shaped module carrier 10 consists of a base plate 36 and legs 38 which are arranged on the base plate 36 on two opposite first sides.
  • the modules 1 are from the rear edge, i.e. shown from the ink supply side.
  • a damping block 5 is arranged on the rear edge on the left and, in addition, electrical control feed lines are provided on the rear edge on the right - not shown in FIGS. 1a to 1c.
  • the modules In FIG. 1a, the modules have been shown opened instead of the control lines to show how the constant distance is effected by means of spacers 19 and / or 20. These are attached to the module standing vertically on a reference plane.
  • the structure of the ink jet print head according to the invention is described below in connection with the edge shooter ink jet in-line module (ESIJIL module) known from application P 42 25 799.9. It consists of at least 3 flat ceramic or glass parts 2, 3 and 4, which are sintered together and at least partially embedded in a protective coating 22 (synthetic resin). In the surface of only one ceramic or glass part 2, nozzles are incorporated on a nozzle channel plane 100, the nozzle openings of which form a line on the front of the module part 2. If modules based on the edge shooter principle are used for the inkjet printhead, the reference plane is formed by one surface of a module part 2 or 3, which lies parallel to the nozzle channel plane 100.
