Reservoir of a printing device and a method for emptying an exchangeable reservoir of a printing device

The invention relates to a reservoir of a printing device according to the preamble of claim 1 and claim 2 and a method emptying a

replaceable reservoir of a printing device.

There are storage containers for use in printing devices, in particular

Printing machines, for example, in inkjet printing devices for industrial applications and in the home and office area known. Such storage containers are preferably storage containers for operating fluids of the printing device, in particular ink reservoir and / or solvent reservoir. In this case, reservoirs are used with a dimensionally stable outer body, which have in their interior at least one shape-variable storage body, usually in the form of a bag, which contracts during a removal of the corresponding operating fluid, for example, during ink withdrawal. The outer body also often have other elements, such as electronic circuits and

Memory devices, via which information, for example, on the current filling level of the reservoir and / or a kind of content and / or

Manufacturer information and / or a date of manufacture, etc. can be replaced with the printing device. Depending on the operating time, for example, this data can be written updated in this memory. This makes it possible

For example, to issue a warning as soon as, for example, the quantity in the

Reservoir falls below a certain value, so that the user can replace the reservoir in time for a new one.

In addition, said outer body frequently, in particular at Printing equipment in the office sector and / or labeling systems in the

industrial area, additional facilities, such as electronic and / or fluidic devices, such as ink filters and / or nozzles with associated control devices, so that the outer body in conjunction with these additional facilities is a functioning pressure module, which can be operated for example via external electrical control signals ,

Therefore, such a pressure module has a considerable complexity, whereby both manufacturing costs and operating costs are relatively high, since usually after emptying of the reservoir and in particular of the storage body, the complete print module is replaced and disposed of.

Storage tanks in a simpler design, for example, have only a dimensionally stable outer body with an in-mold variable storage body, such as bags, and in addition to electronic devices for

Exchange of information. As a result, the complexity of the entire reservoir is lower, and thus manufacturing costs and operating costs are lower. Also, such reservoirs are usually after emptying as a whole

replaced.

Reservoir in even simpler design, however, have only a container that is either designed as dimensionally stable body and when emptying requires additional facilities for ventilation or designed as non-dimensionally stable body, such as a bag that requires a corresponding elaborately designed recording device for its support.

A communication of said electronic devices with a

Machine control of the printing device is usually via electrical contacts, via which the power supply of the electrical device to the reservoir and the data transfer between the reservoir and the control system of the printer takes place. For this purpose, the receiving device for the storage container, for example, a series of contact pins, which in an inserting and fixing the

Reservoir in the receiving device come into contact with corresponding contact surfaces on the reservoir, whereby the electrical contacts come about. This can lead to difficulties in particular in the industrial use of pressure equipment or labeling devices that the contacts of both sides are at least temporarily unprotected, whereby the risk of oxidation of metal surfaces and / or contamination of the contact surfaces by oil, dust, moisture or leaked ink , which can lead to the failure of the communication and thus to a fault condition of the entire printing device.

In particular, inks and solvents used for industrial applications are sometimes very aggressive or have high adhesion

a variety of materials, resulting in contamination of the contacts with such inks to increased cleaning effort.

Furthermore, difficulties may arise in that the mechanical alignment of the reservoir to the receiving device must be very precise, creating a precisely executed recording device is required and the fixation of the

Reservoir must be made with a sufficient contact force, by means of which the contact surfaces are pressed together. This can be impaired in particular by wear.

By the US 2008/0186367 A1 a storage container of a printing device is known, wherein the reservoir has at least one opening and wherein at least one of the opening facing surface element of an outer side of the reservoir has a pointing in a first direction surface normal and wherein the

Storage container has at least one data module, the at least one transmitting and / or receiving unit for contactless communication with at least one Communication module of a printing device and wherein on the data module data is stored, which can be read by means of at least one communication module of a printing device.

By US 2008/0186367 A1 a printing device is further known, wherein the printing device has at least two receiving devices for receiving a respective storage container and wherein the printing device at least one

Communication module and wherein the at least one communication module has at least one transmitting and / or receiving unit, which is suitable for a contactless data transmission between this transmitting and / or receiving unit and each at least one data module of a reservoir and wherein the

Printing device has at least one line system.

EP 1 060 895 A1 discloses a storage container of a printing device, wherein the storage container has at least one data module which has at least one transmitting and / or receiving unit for contactless communication with at least one communication module of a printing device.

By JP 2001 106 217 A, US 5 234 130 A, WO 2007/006109 A1, the

DE 10 2006 022 477 A1, US 2001/0013884 A1, WO 99/04979 A1 and the

US 2003/0189623 A1 further storage containers are known.

Continuous ink jet printers have an operating principle in which an ink to be printed from a storage container, for example by means of a

Removed negative pressure and preferably via pumps with positive pressure in a preferably located in a print head pressure chamber is promoted, which has at least one nozzle on a side facing an object to be printed on. From the at least one nozzle ink initially emerges as a continuous ink jet, which decays into individual drops. For this purpose, for example, at least one of the pressure chamber Modulating element attached, which generates pressure fluctuations in the exiting ink jet, so that after leaving the nozzle after a short time at a defined distance breaks up into individual similar drops of ink. The size of the ink drops depends, for example, on the applied modulation frequency, the

Nozzle diameter and the pressure generated by the pump and can be set within the limits set by the combination of the aforementioned parameters for the system. Just before the tearing off of the ink drops from the leaked

Ink jet, the ink droplets are each provided with an individual electrical charge, the height of the charge preferably depends on the desired impact position on the object to be printed.

To ensure electrical charging, the ink has an electrical

Conductivity on. During the charging process, ink droplets have not yet broken off from the ink jet emanating from the nozzle of the ink jet printer so that due to electrical influence free carriers in the ink are moved towards or away from the charging electrode, depending on the polarity and magnitude of an external charging voltage, the ink chamber and thus the ink reservoir

for example, is electrically held at ground potential. The charging electrode has no mechanical contact with the ink jet. If an ink drop now breaks off the ink jet while it is in the field region of the charging electrode, the electrical charges which have moved through the influence in the drops remain in the ink jet

Drop volume and this appears electrically charged even after the demolition. Charge separation takes place just prior to the tear of the drop at the leading edge of the ink jet, and the charge imbalance thus created in the tearing drop is maintained and the drop leaves the field region of the charge electrode negatively charged in this example. On the detached ink droplets, an amount of charge remains, the size of which preferably at a constant electrical

Conductivity of the ink is according to the level of the applied charging voltage. With a change in the charging voltage can thus also the amount of charge on each drop to be changed.

On their initially linear flight, the electrically charged ink drops subsequently enter the electrostatic field of a plate capacitor and, depending on their individual charge, are more or less deflected from their rectilinear trajectory and fly off the electrostatic field at a certain angle dependent on their charge their original trajectory continues. With this principle, different impact positions can be selected on a surface to be labeled with individual ink droplets, where in this

Execution only in a deflection takes place. To hide individual drops from the typeface or when not to be printed, the ink droplets receive a certain fixed charge or remain uncharged, so that they meet after exiting the electrostatic field of the plate capacitor in a collection pipe, from where they via a pump system in the Ink tank are pumped back. As a result, the unprinted ink circulates in the circle, resulting in the label continuously working

Inkjet printer has led.

The inks used for this purpose have certain required or desired

Properties such as the mentioned electrical conductivity or the shortest possible drying time. In particular, a short drying time requires the use of volatile solvents as the carrier liquid in the ink. When

Solvents are used for example methyl ethyl ketone, alcohols, acetone or generally organic solvents. Due to the principle, it is so that even in the non-printing operating state ink drops from the said nozzle emerge and only after a certain distance in the ink jet print head on the

Trap pipe are returned to the ink circuit. During their flight along this route, the ink droplets are exposed to the ambient air, losing some of their solvent due to the volatility of the solvent mentioned and used in the ink. This lowers over a longer period of operation the ink jet printer continuously the proportion of solvent in the existing in the ink circulation ink, which leads to an increase in the viscosity of the ink and thus would lead to malfunction or failure of the printer. To avoid this, the ink is continuously or at regular intervals or as needed fed a certain amount of solvent from a dedicated reservoir. This happens, for example, by timed a specific

Solvent amount is supplied to the ink system or via a

Viscosity measurement is supplied as needed a certain amount of solvent. For this purpose, different pumps and / or valves and / or filters and / or measuring devices are provided in the ink system, which must be brought into different contact with each other as needed. There is therefore a need for extensive tubing between these facilities

To ensure functionality.

Usually, the respective devices such as pumps and / or valves and / or filters and / or measuring devices are mounted on at least one base plate or mounting plate. A tubing of the individual devices with each other is usually made by means of respective hose connections, which requires a considerable amount of time in the production. In addition, the tubing of each device is prone to error, which can lead to a considerable rework. In addition, it is often necessary for service purposes at least certain hose connections releasably design, resulting in increased costs due to the fasteners to be used. In addition, it is often not possible due to the available space in the housing of the inkjet printer to arrange all facilities optimally accessible, which in case of service to complex installation work and thus significantly extended downtime of the

Inkjet printer can lead.

EP 1 205 309 A1 discloses a printing device which has a line, wherein the printing device has a base body having a first and a second main side and wherein the base body has two passages connecting a channel with the second main side of the base body and wherein a

Ink reservoir on the second main side of the at least one base body connected to one of the two passages of the at least one channel and / or connectable.

WO 83/00932 A1 other printing devices are known.

In pressure device piping systems, pressure fluctuations can occur due to inserted pumps, which can adversely affect, for example, discharge behavior of operating fluids, such as ink ejected from an ink jet printhead. This is due to the fact that in the

Inkjet printhead should prevail as constant pressure conditions to ensure a smooth operation. As a rule, however, the pressure fluctuations can continue from the corresponding pump to one end of the line system, for example to at least one print head.
