Definitions

  • the invention relates to a printing machine for ink-jet printing on containers provided in a container stream.
  • inkjet printing on containers which are conveyed in a continuous or intermittent container stream, comparatively large quantities of ink are needed, which usually do not fit into printer cartridges in the area of the print heads used for printing. It is therefore known to arrange ink reservoir stationary in the range of machine bases. With such storage containers can indeed provide the required quantities of ink for the operation of printing presses. However, depending on the color of the imprint to be applied, several such reservoirs are required, which usually have to be refilled at different times.
  • the efficiency of the printing operation is particularly limited with increasing number of processed ink types due to frequent production interruptions. This has a negative impact especially on the machine availabilities required in beverage bottling plants.
  • a printing machine according to claim 1. Accordingly, this least comprises a printing unit for printing on the containers and a filling station associated with the printing unit with a filling mechanism which is accessible so that ink can be filled and / or topped up during the printing operation of the printing machine without stopping the printing press.
  • the ink can be filled during the movement of an existing on the press transport means for the container, in particular a carousel-shaped container table.
  • an accessibility according to the invention is to be understood that operating personnel has a lateral access to the filling mechanism, for example in the periphery a container carousel, in a region outside co-rotating machine components, and preferably outside the monitored engine guard.
  • the filling mechanism is to be understood as a filler neck or the like and generally as a filling device with which the printing press can be connected to an ink supply unit, for example to a transportable ink container, a supply line or the like.
  • an ink tank can then be suitably inserted, attached and / or put over in, on and / or via the filling mechanism / filler neck.
  • a filling mechanism based on a hose, with which ink can be sucked out of a provided container, tank or the like, or with which a temporary connection to a central ink supply system can be established.

  • the ink container is meant for example a canister or the like, in particular a container that can be handled by a single person.
  • the filling mechanism comprises an opening facing upward and in particular upward funnel-shaped opening for an ink tank.
  • a portable ink container with downwardly facing container mouth can be inserted into the Einglallme- mechanism. This facilitates in particular a complete emptying of the Tintenbe-container and makes it unnecessary to aspirate ink residues from the ink container.
  • a cannula for penetrating a closure present on the ink container.
  • an ink tank can be sealed in the Introduce condition into the filling mechanism and open under liquid-tight conditions in the filling mechanism and purposely emptied through the cannula.
  • the cannula is formed, for example, centrally in the cross section of the filling mechanism.
  • a needle, knife or similar blade could be present in the fill mechanism to penetrate a closure or suitable wall portion of the ink container and open the ink container such.

  • the filling mechanism could be formed as an inner cone and the neck of the ink container as a corresponding outer cone, which can be pushed together in a liquid-tight manner.
  • elevations and / or depressions for mechanical coding are formed on the filling mechanism, such that only ink containers suitable for mechanical coding can be guided to the cannula.
  • the opening of an unsuitably coded Tintenbe container, and thus filling with a wrong type of ink, can thus be easily and reliably prevented.
  • the filling mechanism and ink container are then provided as corresponding sets.
  • the filling station comprises a protective door designed in particular as a lifting / sliding door, the closed state of which is secured by a locking, preloaded lock.
  • a protective door designed in particular as a lifting / sliding door, the closed state of which is secured by a locking, preloaded lock.
  • the lock is held in a locking position, for example by spring force.
  • unlocking for example, a manual intervention by operating personnel is necessary before the protective door can be opened.
  • the protective door prevents unintentional opening of the filling station and thus caused impurities, in particular the filling mechanism.
  • the protective door is coupled to a ventilation device to automatically ventilate the Tintenbenzol ter when closing the guard.
  • a ventilation cannula can thus be pushed through a wall region of the ink container when the protective door is closed.
  • the ventilation cannula thus enables the subsequent flow of air when emptying the ink tank.
  • a particle filter is present on the input side of the ventilation cannula, which prevents suction for the pressure operation of harmful particles.
  • the aerator for example in the form of a cannula, may also be mounted in close proximity to the aspiration cannula so that both devices are pierced over the same area on the filling mechanism.
  • the suction and ventilation cannula may be combined as a cannula with two parallel channels.

  • the storage tank serves as a supply tank for the current printing operation.
  • the storage tank is thus formed stationary on the printing press and firmly connected to the respective inking unit.
  • the ink container according to the invention is a canister, a bottle or the like, which is used for a limited time, only for filling the storage tank, into the respective filling station. This allows a particularly simple and inexpensive design of the ink tank.
  • the storage tank preferably comprises a control device for monitoring its ink level. It can then be in time printing a warning or the like in the current printing operation, so that the storage tank without interrupting the printing operation, ensuring a continuous ink supply, can be filled.
  • the storage tank comprises a stirrer. This is particularly advantageous when using sedimenting ink.

  • the level could be calculated from the operating time / ink consumption of individual printheads.
  • the control unit releases a charge.
  • the ink is then completely emptied from the ink tank via the filling station in the storage tank and / or pumped around.
  • a pump controlled by the control unit for circulating the ink from the filling station into the storage tank is then present.
