Definitions
- the present invention relates to a printing system with an adjustment actuator for adjusting several print heads.
- a wide variety of printing systems with print heads can now print on a wide variety of media, such as paper materials or corrugated cardboard, with the print heads in the printing system being arranged either fixedly or scannably relative to the print medium.
- the printing system must be configured when it is first put into operation, whereby correct adjustment of the print heads in relation to the print medium through orientation and positioning is of great importance. If only individual defective print heads are to be replaced in an already adjusted system, then generally only an adjustment of the new print heads installed in the printing system is required.
- a printing system is a device with the help of which a printing medium can be printed with printing material according to a predetermined pattern.
- a print head in this description, we mean a component with one or more nozzles arranged in one or more rows through which the printing material can be delivered in a precise position and in a direction towards the printing medium.
- An arrangement of nozzles belongs to one and the same print head if the printing system in the application provides that the arrangement can only be positioned and oriented as a whole. "In the application” here means that the print head is assembled and installed in the printing system.
- An actuator is a general term for a component that converts electrical signals into mechanical movement or other physical quantities. Actuators in the sense of the present invention convert electrical signals into mechanical movement.
- an actuator with the help of which a first object (here the print head), with which it is operatively connected, is positioned and oriented relative to a second object. (here e.g. printing medium to be printed and/or adjacent print head) can be moved mechanically.
- a first object here the print head
- a second object here e.g. printing medium to be printed and/or adjacent print head
- Positioning is understood as a shift of the first object into a desired position relative to the second object.
- Orientation is understood as a rotation of the first object into a desired orientation relative to the second object.
