Definitions

  • the invention relates to a device for printing slide frames or the like, with at least one printing device arranged above a transport device for successive feeding, preferably having a dot matrix printer.
  • dot matrix printers or the like for the labeling of slide frames, the print heads of which are arranged in a stationary manner above a transport path for slide frames which are brought in lying down.
  • the slide frames are transported in the transport device, for example by means of a chain with drivers or by means of a toothed belt having drivers.
  • the passage of the slide frames below the printing device takes place continuously, and the printing process takes place while the slide frame is being moved under the print head of the printing device.
  • Devices of this type are used, for example, in separate labeling systems or are also installed, for example, on slide framing machines as additional devices.
  • the printing device can have one print head or a plurality of print heads.
  • the device For the printing process, an exact adjustment of the device to the thickness of the surface element to be printed or the thickness of the slide frame is required.
  • the frame thickness varies from make to make, and differences in thickness can also be determined within the same make.
  • the invention has for its object to design a device of the type mentioned so that an automatic adjustment to the respective frame thickness takes place.
  • this object is achieved in that the pressure device is arranged such that it can be moved transversely to the plane of the transport device of the slide frame or the like, counter to the action of force. It is preferably provided that the plane of the transport direction of the slide frames or the like is arranged to run essentially horizontally and the force is exerted by gravity.
  • the printing device is thus raised by a slide frame brought up on the transport device by an amount corresponding exactly to the thickness of the slide frame, and the height of the printing device above the transport device is thus automatically and precisely adjusted to the individual frame thickness of the corresponding slide frame or the like.
  • sliding devices are provided in front of and also behind the print head of the printing device, above the movement path of the slide frames or the like. These sliding devices are preferably designed as ball bearings.
  • the printing device can be easily removed from its guide. In this way, the printing device can be cleaned after being removed and reinserted without any tools or the like being required.
  • a device for printing slide frames has a transport device for the successive feeding of lying slide frames 2. Only one slide frame 2 is shown, which is moved continuously in the direction of arrow A (transport direction). The movement takes place, for example, via a chain (not shown) with drivers (also not shown).
  • a printing device generally designated 3 has a dot matrix printer 5 with a print head 6 on a frame 4. Ribbon rolls 7 and 8 are also mounted on the frame 4, the ribbon 9 of which is guided below the print head 6 via deflection rolls 10, 11, 12 and 13. Seen in the direction of transport A in front of the print head 6 of the printing device, ball bearings 13a, 14, 15 and 16 are arranged. Ball bearings 17 and 18 are provided behind the print head 6.
  • the frame 4 and thus the entire printing device 3 including the ink ribbons, the ink ribbon guides and the ball bearings are arranged to be vertically movable. For this purpose, a guide (not shown) is provided, in which the entire printing device can be guided in the vertical direction without play but easily movable.
  • the printing device with the ball bearings 13 to 18 rests on the slideway 19 of the transport device 1.
  • the arrangement is designed in such a way that when ball bearings l3 ⁇ to 18 rest on the slideway 19 between the slideway and the underside of the ink ribbon 9 there is still a small gap.
  • the latter can be removed with the frame 4 from its guide upwards without any tools or the like being required.
