Definitions
- the invention relates to a device according to the preamble of claim 1.
- a printing device of this type is, for example, from WO-A-90/10917.
- the one described there Printing device the printhead is a needle printhead, who can either print a receipt or a receipt can.
- GB-A-2 022 023 shows a similar printing device known in which the print head between two print areas around a parallel to the line direction Swivel axis is pivotable.
- the printhead designed as a needle print head.
- JP-A-59190858 there is an ink printer with and described only one print area, the ink print head is arranged on a carrier in the printing line direction adjustable across the print area of the print head and its ink print head by turning the Carrier around a perpendicular to the print line direction Axis between the print area and a maintenance station is adjustable.
- the invention has for its object a printing device the known type so that as a printhead an ink printhead can also be used.
- the printhead is an ink printhead attached to the carrier in a different from the working positions Rest position and together with the carrier in the direction of the printing lines between one encompassing the work areas Printing station and one outside the work areas Maintenance station is adjustable.
- the Maintenance station a cover device for covering the the nozzle area containing the ink outlet nozzles Printhead and / or a cleaning device for cleaning the nozzle area.
- the solution according to the invention offers the possibility of the maintenance station outside the printing station to arrange so that the adjustment of the printhead within the printing station between its two work areas is not hindered.
- the already existing actuator for adjusting the Carrier used to move the printhead between the Pressure station and the maintenance station. Thereby the additional effort for arranging the Maintenance station reduced to a minimum.
- a printing device of the type described is the travel of the print head in the direction of the print line relatively low.
- the printhead has this arrangement an ink tank that connects to a hose ink reservoir located outside the printing station connected is.
- the printhead can be attached to the carrier at a right angle whose direction of adjustment axis pivotally mounted be like this, for example in the above WO90 / 10917.
- the working positions can the print head against each other by 180 ° be offset.
- the rest position is the print head conveniently in the middle between the two working positions, i.e. she is opposite each offset by 90 °.
- a nozzle area containing the ink nozzles Printhead expediently in the rest position of the same essentially perpendicular to the direction of adjustment of the Carrier directed. This offers the possibility of the printhead with the nozzle surface at the transition from the printing station drive into the maintenance station against a cover, so that it can be stationary and itself does not need to be moved.
- the print head on the carrier by one to the direction of adjustment the same parallel axis between the working positions and the rest position can be pivoted.
- the nozzle surface parallel to the direction of adjustment of the carrier it is expedient if the covering device, the cleaning device and / or the refill device the maintenance station perpendicular to the direction of adjustment the wearer is adjustable.
- the printhead can easily enter the maintenance station retracted, on the other hand the contact between the printhead and the maintenance station devices getting produced.
- the printing device comprises a generally designated 10 and only indicated schematically Chassis in which two guide rods 12 are arranged are on which a carrier designed as a carriage 14 for a print head 16 is slidably guided.
- the carrier 14 can be attached to it with the aid of a Belt 18, which is driven by a motor 20 Pinion 22 is guided along the guide rods 12th be moved.
- a frustoconical turntable 24 On the support 14 is a frustoconical turntable 24, to which the ink print head 16 is attached to a to the longitudinal direction of the guide rods 12, i.e. to the displacement path of the carrier 14 vertical axis of rotation 26 rotatable stored so that the ink print head 16 between two Swiveled working positions offset by 180 ° can be shown in Figures 1 and 2 by solid lines or dashed lines are shown are.
- the ink printhead is in a first working position 16 assigned to a first work area, in which he arranged a receipt strip 28 and one next to it Journal strips 30 can print.
- the receipt slip and the journal strip are each from a supply roll 32 coming, via drive roller pairs 34 and 36 led to a take-up roll 38 through the printing zone, in which one of the ink nozzles of the ink print head 16 containing nozzle surface 40 are opposite.
- the ink printhead is used in the second working position 16 for printing on a document 41, which can be printed using Transport roller pairs 42, 44 in a suitable printing position can be brought in which it the nozzle surface 40th the ink print head 16 is opposite.
- the ink print head 16 can also be in one versus both Working positions offset by 90 ° each dash-dotted lines in the rest position indicated in FIG. 2 be pivoted in the nozzle surface 40 vertically is directed to the direction of adjustment of the carrier 14.
- the actuator 20, 22 With the help of the actuator 20, 22, the carrier 14 and with it the print head 16 from which the work areas encompass Printing station in a generally designated 46 Maintenance station.
- the printhead 16 an ink tank, not shown, which via a hose 48 with one outside the printing station ink cartridge disposed in the maintenance station 46 50 is connected. If such a hose connection not appropriate or undesirable for other reasons the maintenance station can also be a refill device included, with the help of the ink tank the print head 16 from the ink cartridge 50 again Can be refilled when it is in the maintenance station 46 is located.
- the ink print head 16 is on the carrier 14 by one the longitudinal direction of the guide rods 12 parallel Pivot axis 52 is pivotally mounted.
- the working positions, in which the ink print head 16 optionally the receipt strips 28, the journal strip 30 or a receipt 41 can be printed, are by solid lines or dashed lines Lines reproduced and 90 ° against each other added.
- the rest position of the ink print head 16 is indicated by dash-dotted lines and opposite the Position of the ink print head for printing a receipt offset by a further 90 °.
- the ink print head 16 on the one hand without problems in the outside of the printing station provided service station 46 driven and on the other hand be brought into contact with the maintenance station 46 can, this or at least part of it in Direction of the double arrow A in Figure 3 on the print head 16 can be adjusted to or from this.
- This adjustment can be done by a motor, for example, provided in the maintenance station to drive a pump is the ink in a manner known per se by the Ink printhead nozzles for cleaning them.
- the maintenance station located next to the printing station at a location where for example, drive elements for driving the carrier and the artwork are arranged so that the Width of the printing device is not increased.
