Definitions

  • the invention relates to a device for receiving a combination of two variable volume chambers and a plurality of valves for constituting an ink supply circuit of an ink jet print head.
  • the present invention aims to solve this problem and relates to an arrangement of all the means used in a structure which is easy to produce, simple and which leads to an extremely compact final device.
  • a cell as described in the two cited patent applications is illustrated by means of Figures 1a and 1b. It essentially consists of a chamber (1) with variable volume depending on the displacement of a piston (P). The latter is mechanically connected by means (2) to an eccentric (3) driven by a stepping motor (4).
  • This variable volume (1) is connected on the one hand to a pressure sensor (5), and on the other hand by a pipe (6) to one, two or more valves electrically controlled by coils (b).
  • Only two valves (7) and (9) are represented in FIGS. 1a and 1b, but this number is not restrictive and the application described below will moreover clearly show the use of a plurality of valves associated with a single room. These valves accept both directions of fluid circulation and are normally closed in the absence of an electrical signal.
  • the position of the drawer (t) shows for example that the valve (7) is in the blocking position in FIG. 1b and in the open position in the figure. 1a, and vice versa for the valve (9).
  • a throttle (8,10) On the outlet pipes of each valve is normally provided a throttle (8,10).
  • These throttles are designed so as to create a pressure difference at their ends when a flow of fluid of non-zero viscosity passes through them, which can be expressed in terms of pressure drop. They are capable in particular of demonstrating, in the form of a pressure difference ( ⁇ P), the viscosity of the fluid during a pulse of fluid flow.
  • These throttles can for example consist of a tube integrated in series in the hydraulic circuit, this tube having a length significantly greater than the diameter of said tube. For example, the length is approximately 15 times the diameter of the tube through which the fluid passes.
  • the arrows (F3) and (F4) symbolize the flow.
  • the generation of a fluid flow is done in two half-cycles.
  • the first ( Figure 1a) consists in controlling the opening of the valve (7) during the half-turn of the motor rotor from a 0 ° position to a 180 ° position, i.e. the time when the volume of the chamber (1 ) increases; the fluid is sucked in (arrow (F3).
  • the second half-cycle ( Figure 1b) consists in controlling the opening of the valve (9) during the next half-turn of the motor rotor from 180 ° to 360 °, i.e. time the volume of the chamber decreases; the fluid is discharged (arrow F4).
  • valve-throttle couples on the same variable volume chamber, in order to create a multi-inlet / multi-outlet pumping system, as described in the applications for main patent and certificate of addition cited above.
  • the configuration of a circuit implementing such a cell allows direct measurement of a pressure by means of the sensor (5) by direct connection of the chamber (1) with the member whose pressure.
  • the valve which controls this downstream organ is then maintained in the open position, the engine is stopped and the pressure sensor (5) is then directly in communication, via the chamber, with said member.
  • FIG. 2 An alternative embodiment of such a circuit is illustrated by means of FIG. 2 in a static configuration, all the valves being in the closed position.
  • This circuit includes four tanks, two of which are removable.
  • the reservoir (15) is a cartridge containing ink (30) in reserve, not yet used.
  • the reservoir (15) is removable.
  • the reservoir (16) is a cartridge containing the pure solvent (31) of the ink used.
  • This reserve solvent (31) makes it possible to top up the solvent necessary for maintaining the viscosity of the ink used and recycled in the system.
  • the viscosity of the ink of the jet is linked to an evaporation of the solvent during the recycling of the ink.
  • This reservoir (16) is also removable.
  • the reservoir (18) containing the ink (34) functionally fulfills the role of a pressure accumulator which is used in order to transform the pulsed flow rate of the cell when it is used in the pumping cell, into a constant flow rate at fixed pressure, and directly intended for forming the jet (21).
  • This reservoir contains a pocket of air (180) under pressure which acts as a shock absorber. This air pocket (180) is renewed each time the printer is started.
  • the role of the reservoir (17) is to receive the recovery ink (33) and the air returning from the gutter (22), and to separate them.
  • the ink necessary to maintain the pressure in the accumulator (18) is taken from this reservoir.
  • Each of these four reservoirs (15, 16, 17, 18) is connected, by a general pipe (66), to a first variable-volume chamber (1) by means of a valve-restriction pair (9-10 ) for the reservoir (18); (7-8) for the reservoir (17); (11-12) for the tank (16); and (13-14) for the reservoir (15).
  • This set the heart of which is the chamber (1), bears the general reference (A).
  • a second variable volume chamber (23) also cooperates with a plurality of valves. This combination is referenced (B).
  • This second chamber (23) is combined with a set of two valves (24,25).
  • This chamber being mechanically coupled to the eccentric (3) common to the first chamber (1), the synchronism of the valves which are attached to it follows from the synchronism of the chamber (1).
  • a pipe (220) connects the reservoir (17), called the buffer reservoir, directly to the recovery gutter (22). This reservoir (17) can be placed under vacuum.
  • a valve (26) is connected on one side to the pipe (66), and on the other to a condenser (300) comprising a receptacle for the condensate (301) and an evacuation (303) of volatile products.
  • the pressure sensor (5) is connected to this first chamber (1) and allows a whole set of controls and measurements.
  • this supply circuit has only one sensor, the pressure sensor (5), and that this single sensor (5) allows all the measures necessary for the proper functioning of the assembly, namely the pressure measurement of the ink supplying the jet, the viscosity measurement of the ink, the level control of the reservoir (18) during the regeneration of the air pocket, measurement of empty tank level (17), measurement of low level and empty level of solvent tank (16), measurement of ink viscosity of tank (15), related parameter in particular at the temperature, the measurement of the low level and of the empty level of the ink tank (15), the synchronism of operation of the valves with the position of the rotor of the engine (4).
  • this single pressure sensor (5) alone replaces all the sensors that are necessarily encountered in supply circuits of currently known types.
  • valves (19) and (28) are directly linked to the operation of the jet (21) emitted by the print head (T) and are part of the known art, in particular by French patent application 8316440 filed by the Applicant and published under the number 2.553.341. For this, this combination is fictitiously isolated from the rest of the circuit by means of a rectangle (150) in broken lines.
  • the valve (19) is respectively connected to the pressure tank (18) on the one hand, and to the head (T) which generates the ink jet (21) on the other hand, and the valve (28 ) is connected to this head (T) and to the reservoir (17) via the pipe (170).
  • the motor (4) rotates at constant speed cyclically, so that the two variable volume chambers (1) and (23), which are mechanically coupled, each generating their volume cyclically.
  • This rotation cycle has a stop at each turn for the time necessary to the measurement of a static pressure, pressure measurement not influenced by the differential pressures induced by flow rates in the throttles (8), (10), (12) and (14).
  • This allocated time allows the measurement of static pressures, of the ink of the cartridge (30), of the solvent of the cartridge (31), and of the ink under pressure (34) of the reservoir (18).
  • the present invention relates to a device intended to receive all the elements of the ink circuit previously described and directly intended to cooperate with the two chambers (1) and (23) belonging respectively to the element (A) said pressure pump , and to element (B) said vacuum pump.
  • this device (100) consists of a single piece of parallelepipedal shape made of an electrically insulating material and resistant to chemical attack such as for example Polyphenylene Sulfide said PPS.
  • the device (100) according to the invention is first illustrated by means of FIGS. 3, 4 and 5 which, by drawing artifices, make it possible to see the housings and cavities produced inside the one-piece part by removal of material which, in reality, surrounds these dwellings. This representation is made for the sake of clarity and for a better understanding of the invention, without having to resort to too high a number of sections and sections which would weigh down and confuse the description.
  • Figure 3 shows the monobloc device (100) oriented so that the eye of the observer sees the plane upper of the housing intended to receive the pressure sensor (5) as well as, in the foreground, the set of radial star cavities (11a, 13a, 9a, 7a, 26a) and the double cavity (24-25) a , the central housing (202) thus being partially hidden by all of these cavities.
  • FIG. 4 shows this monobloc device (100) oriented differently so that the eye of the observer sees, this time, in the background, all of the radial cavities and, in the foreground, the housing receiving the pressure sensor (5) and the base (600) carrying the piston (P) in fact constituted by the stacking of two parts (P1) and (P2) (see Figure 10).
  • the function of the holes (t1, t2 ... t n ) illustrated in particular in FIG. 4 will also be defined later.
  • the pipes are also made in the mass of the one-piece device (100). Their outings, which lead in variable volume chambers, bear the index (b) ( Figures 8 and 9); their opposite outputs bear the indices (a) such as (C 26a , C 11a , C 13a , C 9a , C 25a , C 24a , C 7a ).
  • indices (a) such as (C 26a , C 11a , C 13a , C 9a , C 25a , C 24a , C 7a ).
  • FIG. 5 illustrates the one-piece device (100) already described by means of the two figures 3 and 4, but this time the observer sees it in an opposite position, the radial cavities are seen below.
  • the two additional cavities (28a) and (28b) which have been, for reasons of clarity, deliberately omitted in Figures 3 and 4.
  • valves (13, 11, 7, 9, 19, 28, 24, 25, 26) are embedded in their respective cavities, by example and without this being limiting in the manner illustrated by the two figures 6 and 7.
  • the valve (13) of diameter (d) is shown in these figures. It is an in-line type electromagnetic valve, the two ends (e1) and (e2) of which are embedded in two grooves (g1, g2) provided for this purpose in the cavity.
  • the hatching (PM) here symbolizes the material which is absent in FIGS. 3, 4 and 5, as has been said previously.
  • Two O-rings (j1) and (j2) seal.
  • a holding system (140a) pushes on the valve concerned, the valve (13) for example, of diameter (d) to keep it in its housing.
  • This system (140a) can be integral with the flange (140) which holds the sensor (5) in place ( Figure 10) and thus hold all the referenced valves (11, 9, 7 and 26).
  • Figure 6 is a longitudinal section and Figure 7 is a section transverse. This method of fixing the valves is not limiting. As has just been said, they are therefore in-line electromagnetic valves with reversible operation.
  • FIG. 8 illustrates a sectional view of this device (100), made at the level of the variable volume chamber (1) (element A).
  • This section takes account of the presence of the material (M) absent in the preceding figures 3 to 5.
  • the section of the device (100) is square.
  • FIG. 9 illustrates a sectional view of the device (100) produced at the level of the variable volume chamber (23) (element B) where the double cavity (24,25) a is represented with its two outputs (C 24a ; C 24b ) and (C 25a ; C 25b ) as well as the two cavities (28a) and (19a). All the valves and the pipes of the device (100) are connected to each other and to the various reservoirs as well as to the print head, in an exemplary embodiment that is in no way limitative, according to the diagram illustrated by means of FIG. 2.
  • such a device (100), as shown in Figure 10 which is a sectional view, is intended to cooperate with a reservoir block (300) as is now described.
  • the device (100) therefore consists of a solid monolithic block in which we find all the cavities previously described.
  • a pipe (Cp) communicates the pressure sensor (5) with the variable volume chamber (1).
  • a flange (140) holds this sensor (5) in place and has profiles (140 a ) serving as supports for the valves such as (26) intended to be embedded in the cavity (C26 a ).
  • the piston (P), as has been said previously, is constituted by the stacking of a base (600) and two parts (P2) of diameter ( ⁇ 2) and (P1) of diameter ( ⁇ 1).
  • the first part (P1) delimits thanks to the installation of a first sealing membrane (m1) and a flange (bd1), the variable volume chamber (1).
  • the second part (P2) thanks to the installation of a second sealing membrane (m2) and a second flange (bd2), delimits the variable volume chamber (23).
  • a set of screws passing through the holes (t1) to (t n ) already mentioned maintains the two flanges (bd1) and (bd2) which pinch the two membranes (m1) and (m2) respectively.
  • the piston (P) is connected via the base (600) to a connecting rod (500) connected via an eccentric (3) supported by a bearing (181) to a motor (4) carried by an engine support (171).
  • the one-piece reservoir block (300) is made, like the device (100), of insulating material and resistant to chemical attack, and is secured to this device (100) by any known means.
  • the block (300) is disposed between the engine block (170) and the device (100) and comprises two compartments which perform the function of the tanks (17) and (18), and a passage (167) through which the connecting rod (500 ).
  • the tank block (300) is positioned between the engine block (170) and the device (100).
  • This arrangement makes it possible to obtain a maximum length of the connecting rod (500). Now, the greater this length, the smaller the angle that this connecting rod will guide at one of these ends by the eccentric (3) and at the other by the part (P1) of the piston (P), and the more precise the guiding of this piston (P) will be, all maintained in an area of isostatic mechanics with quite remarkable compactness qualities.
  • the cartridge holders (157) On the sides of the device (100) are arranged the cartridge holders (157) (only one is visible in this figure), the second being placed in front of the section of FIG. 10. These are the cartridge holders receiving the ink (15) and solvent (16) cartridges. According to a characteristic of the invention, these cartridges are removable and the ink is taken at a trocar (90) whose function is to penetrate a membrane provided for this purpose in the cartridge, pre-perforated EPT membrane using a very fine needle. Under these conditions, the penetration of the trocar (90) having been made without tearing, the sealing of the cartridge is automatically found when the user removes the latter.
  • valves are arranged in a star, as has been seen previously, on the periphery of the variable volume chambers (1) and (23). Under these conditions, we obtain a dead volume of the chamber (1) as low as possible, which leads to a high compression ratio: if there is a little air in the chamber, we can still go up pressure.
  • a device (100) according to the invention is extremely compact and comprises in its mass all the cavities and housings necessary for the installation of all the valves and of the piston delimiting the two variable volume chambers as well as the pressure sensor. It also includes in its mass the maximum number of pipes leading to these rooms and to the outside.
  • such a cell according to the invention allows access to multiple functions although its structure is extremely compact and its operation very simple. It finds its applications in particular in the field of inkjet printing, not only in the context of industrial marking, but also in that of office automation.
