Definitions

  • the present invention relates to a non-return system for ink supply system. It has applications in inkjet printing devices.
  • the invention also covers a cartridge for implementation in said system.
  • the print heads are supplied with ink by means of tanks which are themselves supplied by relatively large cartridges. Because of these volumes, the tank and the cartridges are offset from the head and a hose allows the transfer of ink between the tank and head.
  • the present invention therefore relates to a non-return system for ink supply circuit of at least one head inkjet printing, the circuit comprising a cartridge ink with a body containing the ink supplying a reservoir, the the print head being connected to the tank by a hose, a vent purge being carried out in the tank, the vent receiving a pear or a syringe intended to produce an overpressure in the reservoir to propel the ink toward the print head when a purge operation.
  • the supply circuit comprises between said vent and the cartridge body a valve controlled by at least a movable control rod arranged in the tank, the valve closing the supply circuit in a closed position and leaving the power circuit open in one position opening, the valve being in its closed position when the purge operation and being in its open position when ink supply.
  • the invention also relates to an ink cartridge for implementation in the system according to one or more of previous features.
  • the means of tank fixing arranged externally on the screwing area of the cartridge cap is selected from threaded devices, snap-in, bayonet.
  • the system of the present invention has the advantage of can be purged without the need to remove the cartridge of the tank.
  • a single valve disposed at the cartridge outlet said disc type cartridge valve being controlled in non-return mode by a movable control rod in translation disposed in the tank.
  • a second a butterfly type valve is also arranged in the tank and said tank valve is controlled in non-return mode by a rod of mobile control in rotation.
  • the invention also has the advantage of being able to allow a possible adjustment of the ink flow by controlling the opening one or more valves implemented according to the embodiment main.
  • valve at the cartridge outlet limits the risk of overturning and soiling when handling said cartridge, said valve not being opened and / or controlled by opening / closing only when said cartridge is fixed to the tank.
  • the cartridge 6 is shown disassembled, its different constituent elements being aligned along their axis common mounting.
  • the cartridge 6 has a body 61 generally cylindrical and having an opening at the end a neck 610.
  • the body 61 of cartridge 6 may have a shape other than that shown and for example polygonal. Likewise other capacities than 125 ml or 500 ml can be used artwork.
  • the neck 610 has at its open end a zone of 611 screws with external thread. Col 610 presents between the screwing area 611 and the body 61 an area 612 latching.
  • a detailed example of making a 610 neck is given in Figure 2.
  • the snap-in area 612 comprises in this example six lugs 613 of generally pyramidal shape extending around the periphery of the neck.
  • the cartridge also includes a valve 63 which is normally closed by the action of a spring 64, the ink contained in the body 61 then unable to escape from the cartridge 6.
  • the disc and sound type valve 63. spring 64 are retained in a valve support 62.
  • the valve support 62 which has a flange is arranged in the neck 610 of the cartridge 6.
  • the valve support flange 62 comes in abutment against the neck opening and a cap 60 of cartridge 6 immobilizes the assembly after screwing.
  • the cap 60 is a tubular cylindrical element intended to be screwed onto the neck 610 of cartridge 6.
  • the plug 60 has a spout 600 with a opening; a screwing area 601 and a base 602.
  • the cap 60 has internally in the screwing area 601 a thread complementary to thread 611 of the screwing area of the col 610.
  • the plug 60 also has an external thread in its screwing area 601. This external thread is intended for allow mounting and fixing of the cartridge on a tank described below. In other forms of implementation, envisages a means of connection and fixing of the cartridge 6 on the tank other than a thread and, for example, a bayonet or a snap-fastening, the corresponding members then being arranged externally on the screwing area 601 of the plug 60 and on the tank on which the cartridge is fixed.
  • the plug 60 comprises also internally a valve seat intended to receive the valve 63 to close the spout 600.
  • FIGs 3 and 4 are detailed examples of construction of plug 60.
  • the cut of plug 60, Figure 3 allows visualize flexible blades 603 arranged internally in the base 602 of plug 60.
  • the flexible blades 603 of plug 60 and the lugs 613 of the neck 610 form a latching means intended to prevent the unscrewing of a cap 60 screwed onto a cartridge 6.
  • the cartridge 6 is therefore for single use and we proceed to filling the body 61 with ink before installing the valve support 62, valve 63, spring 64 and the screwing of the cap 60. Once these elements are installed and the cap is screwed on, the cartridge 6 is sealed, the valve 63 being applied by the. spring on the seat of the cap 60 thus closing the spout 600.
  • Usage unique of. the cartridge 6 guarantees the quality of the ink, a subsequent refill of an empty cartridge 6 being practically impossible.
  • Figure 5 an axial view from the side of the base 602 of the cap 60, allows viewing of the flexible blades 603 regularly arranged inside the base 602 of the plug.
  • the cartridge described above is intended to be fixed on an ink tank 3 which is shown in exploded view on the Figure 6.
  • This figure also shows a cover 2 articulated by a hinge 20 and which is intended to cover the cartridge and part of the tank when the system is in normal operation.
  • the reservoir 3 is formed by a body 31 of tank closed by a cover 30, a seal 32 being interposed between the body 31 and the cover 30.
  • a non-return valve 7 ordered is placed in the tank at a canal connecting two rooms.
  • the valve 7 is in this example a throttle and the rotationally actuated control rod is integral of the butterfly. In the closed position of the tank valve 7, this is applied to a valve seat made in the channel so to close said channel.
  • valve 7 for implementation in the tank itself and for example a disc type controlled valve with or without spring arranged in the connecting channel between the two chambers.
  • the control rod integral with the butterfly valve 7 is controlled externally by a rotary control button 71.
  • the butterfly valve 7 implemented in Figure 6 is detailed in Figure 8 where, the butterfly 72 is controlled by a rod control 73 secured to said butterfly. In this example, the valve is directly actuated by a rotary movement of a button 71.
  • the first chamber of the tank is related to the cartridge 6 and therefore includes in. its cover 30 a means of fixing the plug 60, a device with a complementary thread of the external thread of plug 60 in this example.
  • a seal can be placed between the cartridge fixing means of the cover 30 and the stopper cartridge.
  • the second bedroom has at least one opening or purge vent for the overpressure means, bulb or syringe, and which normally ensures ventilation to balance the ink between the tank and the head (s).
  • the second bedroom has in addition to a filter 310 and a nozzle 312 intended to receive a pipe connected to the remote inkjet printhead (s) of the tank.
  • the tank cover 30 therefore has on the side from the second chamber an opening intended to receive a means for overpressure, pear or syringe.
  • the tank may include other organs and in particular a ink level sensor. Cartridge presence contact on the tank and / or hood opening can also be implemented.
  • the valve cartridge is kept open when the cartridge is attached to the reservoir by a fixed finger 311 disposed in the reservoir and in the axis of the cartridge neck.
  • the finger 311 is movable in translation in order to allow the adjustment of the ink flow rate from the cartridge 6.
  • finger 311 or non-return valve control rod is movable in translation and is controlled directly in translation or through of a means converting a rotational movement into a movement of translation.
  • movable in translation can be controlled directly in translation, said finger being accessible below the body 31 tank 3 directly or the control can be deported, by example a way of converting a rotational movement into translational movement being implemented.
  • control rod of the head valve is a movable finger.
  • FIG 9 is an overview of a device printing using the system of the invention.
  • the tank body 31 is not shown.
  • a case 5 print head 50 is offset at the end of arms 4 made from 41 bent tubes. Joints 40 arranged towards the ends of the arms 4 provide a movable connection with the housing in translation along the arms and / or rotation to allow a positioning of the print head box 5 and therefore of the head 50 compared to the items on which printing must be done.
  • the print head box 5 comprises internally an electronic and computer control card ensuring the control and command of the printing system.
  • a cartridge 6 is fixed on the tank cover 30 and the cover 2 is shown partially tilted and open. The disposition relative of the print heads and the tank should be such that the heads are positioned above the level of the tank between a minimum corresponding to the ink flow limit by the nozzle and a maximum corresponding to the air intake limit by the nozzle.
  • Parts of the cartridge, the tank and the head box printing are obtained by molding plastics.
  • the arms can be metallic or plastic.
  • the valves used may be of different types from those indicated, without departing from the scope of the invention, the cartridge valve can implement a tilting disc as well as the tank valve. Likewise the tank valve can set operates a spring means and the control rod acting against said means.
