Abstract

The present invention relates to an ink cartridge filling machine for an ink-jet recording device, which comprises an ink liquid pipeline, wherein an end head at the upstream of the ink liquid pipeline for controlling an air passage and a circuit is connected with an ink source, and an end head at the downstream is connected with an ink cartridge; a branch circuit is arranged between the upstream and the downstream, and the branch circuit is connected with a metering container; a liquid level sensor which is connected with a control circuit is arranged in the metering container. The ink liquid pipeline is provided with a gate-closed type pipeline switch, and the ink liquid pipeline positioned in a pipeline switch section is a flexible pipe. After the metering container with the liquid level sensor is adopted, the sensor can exactly control a set quantity of ink liquid taken out from the ink source to be jetted into the ink cartridge; thus, the quality of the ink cartridge is enhanced. The gate-closed type pipeline switch and the flexible pipe are used for replacing an electromagnetic valve connected in series in the pipeline, so an on-off switch piece to be disengaged from ink liquid with corrosiveness; thus, the corrosion to the on-off switch pipe by the ink liquid can be stopped, and the service life of relevant components and parts can be greatly extended.

Description

Ink jet recording device print cartridge bottle placer

Technical field

The present invention relates to the manufacturing equipment of ink jet recording device, specifically, relate to a kind of isolated plant of black liquid can with print cartridge.

Background technology

In the print cartridge manufacturing process that ink jet recording device is used, adopt bottle placer that black liquid is injected print cartridge usually.Bottle placer is of a great variety, mainly is divided into malleation and Vessel in Negative Pressure Filling two big classes on operation principle.

At CN1371808A, in two parts of Chinese invention patent ublic specification of application of CN1354089A, the applicant has provided a plurality of embodiment of malleation and Vessel in Negative Pressure Filling scheme, the bottle placer that provides with other prior arts is the same, for realizing that print cartridge is carried out this specification requirement of quantitative filling, or employing constant displacement pump, or employing variable pump, or utilize the method for control cylinder stroke, though can both realize quantitative filling preferably, but quantitative accuracy still can not reach desirable requirement, error amount still is bigger than normal in other words, the existence of this excessive error amount directly influences the quality of print cartridge product.

China ink liquid in pipeline from black source to the process that enters print cartridge, must be through controlling mobile all kinds of magnetic valves by certain rule, spool will directly contact with black liquid inevitably, spool and valve seal all can be because of the strong damages rapidly of black corrosion.In addition, when the black liquid pipe interior to bottle placer cleans, many magnetic valves on the black liquid pipeline are cleaned also and will dismantle one by one, not only complexity and cleaning frequency are long.

Summary of the invention

Main purpose of the present invention provides the quantitatively accurate bottle placer of a kind of can, improves the quality of print cartridge product;

Another object of the present invention provides a kind of to the inkless corrosion of valve member on the black liquid pipeline and clean bottle placer easily, and elongated component service life, shortening equipment cleans the time that takies;

A further object of the present invention provides a kind of bottle placer that a plurality of print cartridge fixed bits are arranged, and improves the operating efficiency of bottle placer.

For realizing above-mentioned purpose of the present invention, the ink jet recording device print cartridge bottle placer that the present invention provides comprises black liquid pipeline and control gas circuit thereof, Circuits System, the termination, upstream of China ink liquid pipeline meets Mo Yuan, the termination, downstream connects print cartridge, between the upstream and downstream of China ink liquid pipeline a branch road is arranged, branch road is connected to measuring container, measuring container is built-in with the liquid level sensor that communicates with control circuit, China ink liquid pipeline is provided with pipe switch, liquid level sensor is last, in, following three water-level probes are wherein gone up, middle water level probe plane, place equates with waiting the volume of irritating China ink with the volume that the measuring container sidewall surrounds.

By above scheme as seen, liquid level sensor adopts three water-level probes in upper, middle and lower, wherein goes up, middle water level probe plane, place equates with waiting the volume of irritating black with the volume that the measuring container wall surrounds.After having adopted the measuring container that has the said structure liquid level sensor, can accurately control the black liquid that takes out set amount from black source by sensor and inject print cartridge.

Make the vertical interval that wherein goes up the middle water level probe adjustable, this can realize by water-level probe on the vertical lift or middle water level probe, also can carry out can to the various model print cartridges of difference appearance China ink amount.

Further scheme is that pipe switch is designed to the box-like pipe switch of lock, the black liquid pipeline that is positioned at the box-like pipe switch section of lock adopts flexible pipe, on black liquid pipeline, substitute and be serially connected in ducted magnetic valve with the flexible pipe of box-like pipe switch of lock and switch section, make on-off switch spare and have corrosive black liquid and disengage, degree has cut off the corrosion of black liquid to on-off switch spare, has prolonged the service life of related components greatly.

The termination, downstream of China ink liquid pipeline can move up and down, form to seal and dock or break away from two states with the infusing ink in ink box hole, below the termination, downstream, have one can horizontal plane move the seat, print cartridge fixed bit more than two or two is arranged on the seat, and each fixed bit all can move to below, termination, downstream by a graded.Like this, after a certain particular cartridge carried out can and finish, the termination, downstream can be shifted to another print cartridge fixed bit and carry out can next time, and operating personnel then can take out and insert next one print cartridge to be irritated to this particular cartridge, have improved the operating efficiency of bottle placer.

The technical scheme that the present invention provides, also can be used for the can of multi-cavity colour ink box, at this moment, two covers or the black liquid pipeline more than two covers and control gas circuit thereof, Circuits System are set in every bottle placer, the black source of a kind of color of upstream termination of the black liquid pipeline of every cover, termination, downstream connect the black chamber pouring ink hole of print cartridge corresponding color.Between the upstream and downstream of the black liquid pipeline of every cover a branch road is arranged all, branch road is connected to measuring container, and measuring container is built-in with the liquid level sensor that communicates with control circuit.
