  • EP-A-0 038 630 is a printing device with the features the preamble of claim 1 is known. This has a transport device with a drive and a conveyor track along the the objects to be printed continuously at a defined speed be transported. Furthermore, the printing device according to the State of the art a printing unit with an ink jet matrix print head on which is arranged above the transport track and which the Area of the objects to be printed as they pass the print head printed without contact.
  • the printhead is adjusted to the position of each by means of an adjustment drive customizable printing surface of the objects.
  • this adjustment drive it is a manual drive with which the height of the Printhead at the correct print distance to the top of the same height Items is adjustable. For immediately successive objects with different heights, this adjustment drive is not suitable.
  • the invention has for its object a printing device for continuously moving objects and especially for parcels, to create packaged magazine stacks or the like with which objects can be directly fully automatically and without interrupting your transport flow within the printing device can be printed.
  • An advantage of the device according to the invention is that it does by the contactless printing of the objects in question while moving forward, so to speak, "seamlessly" for example in a fully automatic printing, sorting, bundling and Packaging line for magazines can be integrated.
  • a matrix print head can be done with one and the same Various information, such as different addressees, Magazine titles, copy numbers and the like on the different Stack of magazines applied without any noteworthy conversion work will.
  • the printing device can by its scanning device and the adjustment drive controlled by this for the adjustment the matrix print head to different stack heights (if the top of the stack is printed) or stack widths (if a side Surface of the stack is printed) fully automatically.
  • the scanner also prevents the matrix printhead from touching reaches a stack and can therefore be damaged This prevents interruption of the stack flow. This will increase reliability the device increased. It is also particularly worth mentioning the advantage that with an appropriate design of the adjustment drive and the scanner continuously detecting the shape of the printing surface of each object and a matched automatic tracking of the printhead as it passes Surface on the printhead are possible. Danur can also be on very uneven surfaces Surfaces of objects, as is often the case with particularly high objects Magazine stacks are the case, clean prints are applied.
  • the printing device 1 is assigned a transport table 2, which is about two rotatably mounted deflection rollers 3, 4 carries a conveyor belt 5.
  • the pulley 3 has a rotary drive in the form of a motor 3 '.
  • the Transport table 2 with conveyor belt 5 can also be part of an elongated Transport path of a printing, cutting, sorting and bundling line for Newspapers or magazines.
  • the conveyor belt 5 is a stack of magazines of different heights 6a, 6b, 6c, which are wrapped with packing paper for shipping, in the transport direction 7 brought up to the printing device 1.
  • the printing device 1 has a frame 8 with a foot 9 and a upstanding stand 10, which is in two horizontal, to each other parallel boom 11, 12 continues.
  • an infrared (IR) distance sensor 14 is approximately centered with respect to the width of the conveyor belt 5 arranged vertically above this at a height that is greater than the desired Maximum height of the magazine stacks 6a, 6b, 6c.
  • an ultrasonic distance sensor can also be used will. Both types of sensors are non-contact Scanners that provide high measurement accuracy and operational reliability exhibit.
  • Adjustment arm 17 At the free end 16 of the relative to the transport direction 7 behind the first boom 11 lying second boom 12 is the vertically arranged Adjustment arm 17 attached. This is by means of an adjustment drive in the form of a pneumatic piston-cylinder drive 24 in vertical Adjustment direction 18 slidably mounted on the boom 12. Such Pneumatic piston-cylinder drives of the adjustment arm are commercially available and therefore sophisticated, reliable and easy to control Drives.
  • the adjustment arm 17 carries a horizontal and transversely to the transport direction 7 carrier 19 on which in Transport direction 7 side by side three inkjet matrix print heads 20a, 20b, 20c arranged with the ink jet direction pointing vertically downward are.
  • Such printheads are commercially available and achieve a high contrast and thus clearly recognizable print image. Beyond drawing they are characterized by their particular reliability. Any inkjet matrix printhead 20a, 20b, 20c is one of the three printing lines 21a, 21b, 21c on top 15 of magazine stacks 6a, 6b, 6c assigned.
  • the adjustment arm 17 is continuously between an upper and lower end position adjustable.
  • the inkjet matrix print heads 20a, 20b, 20c are one to a few Centimeters above the conveyor belt 5, so that even very low magazine stacks or, for example, just a packaged single copy can be printed on a magazine.
  • a central, microprocessor-controlled is also on the stand 10 of the printing device 1 Control unit 22 attached, by means of which the entire Printing device 1 is controllable.
  • the pressure control of the print heads and the control of their adjustment drives evaluating the measurement signals of the scanning device (IR distance sensor 14) centrally.
  • the control unit 22 is for receiving the measurement signals of the IR distance sensor 14 connected to the input side thereof.
  • Outputs of the control unit 22 are with corresponding valves of the pneumatic Adjustment drive of the adjustment arm 17 and with the corresponding Inputs of the ink jet matrix print heads 20a, 20b, 20c their pressure control connected. Since the control of the commercial pneumatic drives or the pressure control of the commercially available inkjet matrix print heads 20a, 20b, 20c is known, one is unnecessary more detailed description.
  • a corresponding keyboard (not shown) on the control unit 22 can be placed on top 15 of magazine stack 6a, 6b, 6c texts to be printed can be entered. Such texts can also be found on internal or external data storage can be stored and via appropriate Control commands, possibly via on-line connections with central control units of a production line for magazines be retrieved for expression.
  • the printing device 1 has the following functional sequence: As soon as a stack of magazines 6a, 6b, 6c enters the scanning area vertically below the IR distance sensor 14, the output signal of the IR distance sensor 14 changes from a value which corresponds to its distance from the conveyor belt 5 to a value which corresponds to its distance from the top 15 of the corresponding magazine stack 6a, 6b, 6c corresponds. An output signal which corresponds to a very high distance value is emitted when the very low magazine stack 6c is passed through, whereas an output signal which corresponds to a very low distance value is emitted in the very high magazine stack 6a.
  • the sudden change in the measurement signal when the corresponding magazine stack 6a, 6b, 6c enters the scanning area of the IR distance sensor 14 also indicates the position of the front edge 23 of the magazine stack 6a, 6b, 6c.
  • the corresponding measurement signal is evaluated by the control unit 22, which in turn requires the adjustment arm 17 via the pneumatic adjustment drive within the period of time that the corresponding magazine stack 6a, 6b, 6c needs to move forward from the IR distance sensor 14 to the inkjet matrix print heads 20a, 20b, 20c , to a height at which the print heads 20a, 20b, 20c are arranged approximately half to one centimeter above the top 15 of the corresponding magazine stack 6a, 6b, 6c.
  • the point in time at which the leading edge 23 of the corresponding magazine stack 6a, 6b, 6c runs past the inkjet matrix print heads 20a, 20b, 20c is also sufficiently defined is.
  • the contactless printing action of the print heads 20a, 20b, 20c can begin, which in each case apply the assigned print line 21a, 21b, 21c by spraying ink onto the top of the magazine stack 6a, 6b, 6c.
  • the corresponding conveyor belt speed can also be detected via a tachometer generator 25 which is connected to the motor 3 'coupled and via a signal line 26 to the control unit 22 is connected.
  • the latter evaluates the speed of the stack of magazines 6a, 6b, 6c and can be the exact starting time the printing process after receiving a corresponding signal from the IR distance sensor 14 taxes.
  • top 15 of the magazine stacks 6a, 6b, 6c as they pass at the IR distance sensor 14 can also be detected continuously a non-planar shape of the top 15 registered and the ink jet matrix printheads 20a, 20b, 20c during the time-delayed printing process the actual shape of the top 15 are tracked.
  • the working spaces 28, 29 of the cylinder 30 of the piston-cylinder drive 24 arranged on both sides of the piston 27 are each connected to a multi-way control valve 33 via a pneumatic line 31, 32. This is in turn connected via a further pneumatic line 34 to a pressure source in the form of a pump 35 which supplies a constant supply pressure p max .
  • the multi-way control valve 33 is provided with an atmosphere connection 36, with which it can be connected to the atmosphere. Via an electrical control line 37, the multi-way control valve 33 is connected to the control unit 23, which controls the control valve 33 such that the pressure values in the two working spaces 28, 29 of the cylinder 30 independently of one another to values between the supply pressure p max of the pump 35 and Atmospheric pressure p atm are adjustable.
  • the acceleration and thus the adjustment speed with which the adjustment arm 17 is moved into its printing position can be adapted to the practical requirements via these different pressure values in the two working spaces 28, 29.
  • the lower working chamber 29 is pressurized with the supply pressure p max
  • the atmospheric pressure is set by means of the multi-way control valve 33.
  • the multi-way control valve 33 also has throttling properties in that pressure values can be set in the two working spaces 28, 29 which are between the supply pressure p max and the atmospheric pressure p atm .
  • Position detection device 38 provided the one hand a marker bar in the form of a arranged on the adjusting arm 17 so-called glass scale 39 carries. The latter points in the direction of adjustment 18 Markings 40 arranged equidistant from one another.
  • the position detection direction 38 has a fixed position on the boom 11 Mark sensor 41 on the passing of each Mark 40 recorded incrementally and in the form of a corresponding electrical Signals transmitted to the control unit 22 via the signal line 42.
  • the control unit 22 can in the case of incremental position detection devices usual way the transmitted signals Process and determine the position of the adjusting arm 17 at any time.
