Definitions

  • the invention relates to a printer mentioned in the preamble of claim 1.
  • Interchangeable printheads enable e.g. the use of a printer for different printing processes or types of paper.
  • DE-A-31 07 554 already shows a printer of the type mentioned in the preamble of claim 1. It can be adapted to different types of paper by exchanging the print head and other associated, specific devices. In addition to the print head, transport and guide means for the print carrier and the counter pressure bearing can also be replaced if necessary. All of these functional elements must be individually removed or installed. On the one hand, this means a considerable amount of work, which in general cannot be carried out by the user of the printer because of the adjustment work involved. On the other hand, with the known arrangement there is also the risk that, given the large number of functional elements to be converted, incorrect parts are assigned to one another, which must lead to malfunctions or even damage to the printer.
  • All the essential functional elements belonging to a certain printhead which include in particular the transport and guide means for the print carrier and the platen, are combined to form a unit to be replaced as a whole.
  • the conversion of the printer from one printing process to another is carried out by exchanging only two modules, namely the print head and the structural unit containing the other essential functional elements. It is not difficult to provide two assemblies with markings or coding profiles that make incorrect assignment improbable or impossible.
  • the arrangement according to the invention also enables some extremely advantageous configurations, particularly with regard to the coupling of the transport system to the central drive, which are the subject of subclaims.
  • the transport and guide means for the line feed and possibly also the ink carrier device is designed as a conversion kit, there is the possibility, for example, of a needle printhead with a substantially fixed platen and ribbon as well how to use a thermal print head with rotating platen and thermal transfer ribbon or other combinations, as will be explained.
  • the interchangeable print heads of a printing system are print heads of different modes of operation, which can be controlled by a control device which is uniform for all these print heads.
  • Different mosaic printheads may be mentioned by way of example, e.g. Ink mosaic, needle or thermal print heads, the print image of which is composed of dots in the same way and which are therefore controlled in the same way.
  • an interface between the print head and the control device that is very close to the print head can be selected; the latter need not be replaced, so that a great simplification is achieved.
  • the invention can be used with great advantage above all in printers with several printing stations, for example in cash register printers with one printing station each for receipt, journal and receipt.
  • the basic equipment of the printer can be manufactured in large quantities, whereby the equipment of the various printing stations can be individually defined at any time by the customer at any time up to immediately before delivery.
  • the user can also switch individual printing stations from one printing process to another without having to buy a completely new printer.
  • the printing stations are designed so that all components that belong to the printing systems are interchangeable.
  • at least some of the functional elements forming a printing system are combined to form a whole replaceable assembly.
  • the design and arrangement is such that this assembly is easily accessible and can be assembled and disassembled in a simple manner.
  • the components that are common to all usable printing systems can be arranged stationary in the printer housing. In this way, especially for printers with several printing stations, there is the possibility, for example, of equipping the printing stations that are mainly used with the low-noise thermal printing system, and the less frequently used printing stations with the cheaper needle printing system, which also allows the production of carbon copies.
  • the printing systems can in principle be autonomous, that is to say they can be provided with all the functional elements that are important for their function. However, it is also possible to assign individual functional elements which can be used for a plurality of printing systems to the printer housing, in which case individual functional elements of the exchangeable assembly which are operatively connected to these components arranged in the printer housing can then be assigned to the printer housing the latter automatically connect to these components.
  • a printing system with a serial print head which can be placed on a carrier which is movable in the row direction in the printer housing and a writing surface which is formed on the exchangeable assembly and is stationary during operation is provided as a platen.
  • the interchangeable assembly can also include other functional elements, such as Parts of the guide and transport means for the print carrier contain, as will be explained in more detail later.
  • a printhead which is arranged in a stationary manner in the printer housing and is designed as a thermal writing strip can also be provided, a rotatable screeching roller then being provided on the exchangeable assembly as a platen. The platen rotates when the print medium is transported, so that the platen generally does not need to be lifted off the print medium.
  • the interchangeable assembly between the operating position, in which the platen is in contact with the print head, and a lifting position, in which the platen is raised from the print head is adjustably arranged on the printer housing. This on the one hand facilitates the threading of the print carrier, and on the other hand creates access to the print head, for example for the purpose of an inspection.
  • the conversion kits also include writing tape cartridges, so that certain cartridges can be used either for operation with dot-matrix printing heads or with thermal transfer printing heads.
  • the printer 2 shown in Fig. 1 comprises a printer housing 4, in which a large part of all functional elements of the printer is accommodated, and an attachment 6, which can be placed on the printer housing 4, in which further functional elements combined to form an interchangeable assembly are contained, as well is explained in more detail below.
  • the device shown is a POS printer with three printing stations 8, 10 and 12.
  • a receipt is issued, which can be printed on tape-like paper and torn off by means of a tear-off device 14.
  • a continuous journal strip is printed out in the printing station 10. This is also printed on tape-shaped paper and wound onto a take-up spool 16.
  • the printing stations 8 and 10 are arranged parallel to one another and are printed by a common print head 18 which can be moved in the direction of the arrow 20.
  • the print head 18 is a needle print head or a thermal transfer print head
  • the printing ink is transferred from an ink ribbon 22 to the print carrier 24 or 26 for receipt or journal.
  • the ink ribbon 22 runs out of an ink ribbon cassette 28, is guided over the various printing stations and then runs back into the ink ribbon cassette 28.
  • the printing station 12 is used to print an approximately sheet-shaped printing medium 30, which serves as a payment receipt.
  • a print head 32 is used for printing on the print carrier 30 and is likewise movable in the direction of the arrow 20 and is preferably arranged on a common carrier with the print head 18. As can be seen in FIG. 1, the ink ribbon 22 is guided such that it can also serve as an ink carrier for the printing station 12.
  • the ink ribbon or the printing head is displaced in this station perpendicular to the line direction so that the printing head lies next to the path of the ink ribbon.
  • the attachment 6 contains guide and transport means for the print carriers 24 and 26 as well as the platen against which the print carriers abut during the printing process. These functional elements are different, depending on whether it is in the printing systems used in stations 8 and 10 z. B. is dot matrix or thermal printing systems, as will be explained in more detail below. The entire essay with the one in it contained functional elements combined into an assembly is interchangeable, so that the printer 2 can be converted from one printing process to another in a few simple steps.
  • the attachment 6 is arranged so as to be pivotable about the axis 34, so that the threading of the print carriers 24, 26 running from the supply rolls arranged in the printer housing 4 is facilitated and access to the functional elements arranged in the printer housing 4, in particular the print heads 18, 32 and the ribbon cassette 28 is made possible.
  • functional elements arranged in this attachment are coupled to functional elements arranged in the printer housing 4, as will be explained further below.
  • the transport means 36 and the pressure counter bearing 38 are arranged on a common frame 40 which is mounted in the printer housing 4 so as to be adjustable in the direction of the arrow 42.
  • the pressure counter bearing 38 is designed as a simple pressure bar with a flat writing surface, as is used, for example, in cooperation with needle print heads.
  • the frame 40 with the transport means 36 and the pressure counter bearing 38 are in turn designed as an exchangeable assembly. When changing the printing process of the printing station 12, the frame 40 and the print head 32 are exchanged.
  • FIG. 2 shows a very simplified, schematic illustration of a section through the printer 2 according to FIG. 1. All printing stations 8, 10 and 12 are designed as needle printing stations.
  • the upper printhead 18 interacts with a platen 44 arranged on the underside of the attachment 6, which is designed as a flat writing surface.
  • the attachment 6 also contains guide channels 46, 48 (see also FIG. 1) for the print carriers 24, 26 and counter-rollers 50, which interact with driven transport rollers 52 arranged in the printer housing and further convey the printing paper running off the supply rollers 54. As shown in FIG.
  • the attachment 6 can be pivoted into a lift-off position shown in dashed lines, in which the platen 44 formed on the underside of the attachment 6 is lifted off the print head 18 and the counter-rollers 50 are lifted off the transport rollers 52.
  • This position enables the band-shaped print carriers 24, 26 to be threaded into the guide channels 46 and 48, as well as access to the functional elements arranged in the printer housing.
  • the lower print head 32 also designed as a needle print head, for printing on the print carrier 30 interacts with the pressure counter bearing 38 arranged on the frame 40 and designed as a pressure bar.
  • driven transport rollers 36 are arranged on the frame 40, which cooperate with counter rollers 56 arranged in the printer housing.
  • the frame 40 is adjustable in the direction of the arrow 42. In a lower lift-off position, the platen 38 is lifted from the printhead 32 and the transport rollers 36 are lifted from the counter-rollers 56, so that the pressure carrier 30 can be inserted until it abuts the stop 58.
  • the adjustment option in the direction of arrow 42 also serves to lift the platen from the print head 32 for line transport, as will be described in more detail further below.
  • Fig. 3 shows an arrangement according to Fig. 2, but in which the printing stations 8, 10 are converted for a thermal printing process.
  • the printing station 12, however, is still equipped with a dot matrix printing system, so that it does not have to be described again here.
  • a thermal print head 60 designed as a thermal writing strip is provided in FIG. 3, which is pivotally mounted in the printer housing about an axis 62.
  • a compression spring 64 keeps the print head 60 in constant contact with the associated platen.
  • the attachment 66 corresponds in its shape and dimensions essentially to the attachment 6 in FIG. 2. It also contains guide channels 68, 69 for the print carriers 24, 26 as well as mating rollers, not shown in this figure, which have driven transport rollers arranged in the printer housing work together. This arrangement corresponds to the arrangement shown in FIG. 2 and therefore need not be described again here.
  • a platen roller 70 serves as the pressure counter bearing for the print head 60 and is drive-connected via a drive belt 72 to a pulley 76 arranged on the axis 74 of the counter rollers.
  • intermeshing gears 80, 82 are arranged on the axis 74 of the counter rollers and on the axis 78 of the transport rollers, which transmit the drive movement of the transport rollers in a suitable ratio to the platen roller 70.
  • the attachment 66 is in turn arranged in FIG. 2 so as to be pivotable about the pivot axis 34, so that the gears 80 and 82 come into engagement with one another when the attachment 66 is pivoted into the operating position shown.
  • the thermal print head 60 is constantly against the platen 70 or the print carrier 24, 26 bearing against it, provided that it is a pure thermal print without the use of an ink ribbon or the like.
  • the arrangement is such that the thermal print head 60 lies above the ink ribbon 22, which is still used for the lower printing station 12.
  • FIG. 4 again shows a perspective illustration of details of an arrangement according to FIG. 2.
  • the two print carriers 24 for the receipt and 26 for the journal each run from assigned supply rolls 54 and are guided over the transport rolls 52 against which the counter rolls 50 bear .
  • the print head 18 can move in the direction of the arrow 20 over a line width covering both print carriers 24, 26 will.
