WO2003106930A1 - Hydraulic system for an electric drop-jet printer and a drop trap for said hydraulic system - Google Patents

Abstract

The inventive hydraulic system for an electric drop-jet printer comprises a reservoir and pumping, suction and discharge circuits connected thereto. Said hydraulic system is characterised in that it is provided with a viscometry circuit and a circuit for dosed solvent refilling which is connected to an ink reservoir. Said viscometry circuit comprises a pump of the pumping circuit, a quick-response pressure valve, a measuring receiver, a capillary channel and a viscometric pipe of the ink reservoir. The circuit for dosed solvent refilling comprises the ink reservoir provided with a submersible filter which is arranged on the end surface of an intake manifold connected to the hydraulic system. The peculiarity of the drop trap lies in that, the input channel thereof and a detector of the jet entering said trap are embodied in the form of a single tube which is made maid of a transparent material and forms a meniscus-former incorporated into the clearance of an optical pair.

Л Electrically portable devices that use a high-pressure drop with an acoustic syncronization of explosive particles For this reason, unused droplets must drop a droplet into the trap and, through a clean, low-pressure circuit, will return to the hydraulic system.

Β The immediate proximity to a trap includes a trap, which is a quick signal if there is a risk of falling into a trap or is at a loss of business. By doing so, the trap should be able to ensure reliable printer operation and the required printing quality.

Impact damage indicators are known, using the principle of impact of flying droplets and a sensitive element in the form of a piezoelectric or tensile element

The sensors of falling into a lazy ship of a residual type known to operate on the principle of closure are also known. the electrical circuit in a trap if a droplet or a principle of transmission of droplets of charges leading to the circuit in the circuit breaks into it (also, page 163).

In order to miniaturize the sensor and reduce the size of the print head, the knee-shaped elements are formed directly from the connecting pipe 12

and can be laid in one area along with the trap itself (Fig. 4). In this case, the incident was tilted to this plane at an angle of approximately 90 °.

With the electronic device for registering and processing the movement of meniscus in one of the options, the following solution was implemented to prevent a solution to the conflict. There is a risk of an emergency shutdown of the drip stroke:

1. The system has 2 buffers for accumulating counts:

Χ (ϊ) - the result of accumulation in the first buffer for the current preset time, for example, 1 sec .; Χ (ϊ-1) - The result of accumulation of the second buffer for the previous preset time.

2. The “count” takes any of the following events: - increase in the current rate by more than 10% of the current; thirteen

- the decrease in the current rate is more than 10% current.

3. Each such event is increased by 1 current buffer current accounts Χ (τ), i.e. Χ (ϊ) = Χ (ϊ) +1.

4. The decision to turn off the trap is subject to the following inequality: т (ϊ) -Χ (ϊ-1)> Χ (1-1) / 2 + Χ (ϊ) / 4.

The suction pump 3 operates in a pulsed (pulsed) mode with alternating suction and discharge cycles. Measurement of viscosity occurs during the suction cycle. The bypass valve at the time of the shutdown at this time disconnects the bypass circuit from the discharge circuit, which ensures that the measurement is correct. The fulfillment of the condition (1) ensures the reliability of this cut-off (a transient process in the absence of pressure, i.e., a pressure drop, is faster than in the pumping circuit). Condition (2) also ensures quality prints, since in this case the pressure pulsation in the generator, the droplet is negligible. Therefore, due to the reciprocal valve, the effect of the receiver is eliminated due to the influence of the chain of viscous and other. pulsation circuits in the zone of the generator droplet. The valve 12 is viscous, it allows for additional control of the measuring mode, and, as a result, it uses sensor 11 also for measuring the operating pressure. In this case, a pressure sensor 5 may be missing.

This adds to the miniaturization of the components, as well as the other elements of the pressure, viscous and supply chain are combined. For example, one pressurizing pump is also used for pumping for a number of printheads, and for viscometer, and for profit.

Independent control of all pumps and all solenoid valves allows you to optimize the operation of the hydraulic system and the entire system.
