Definitions

  • the invention relates to a printer mentioned in the preamble of claim 1.
  • Such printers are said to be able to direct the printed print carriers into three output channels.
  • a flap acting as a paper switch is arranged within the transport path for the recording media leading from the printing station to the rear printer side. Depending on their position, the recording media are deflected towards the rear of the printer or upwards. A further splitting of the paths for the recording media is to take place in the upward-pointing output channel.
  • this known device Tokyo Juki Industrial Co, Ltd: JUKI Serial Impact Dot Matrix Printer Model 7200, Engineering Specification.
  • a printer of the type mentioned in the preamble of claim 1 is already known from US-A-4,486,015.
  • This construction makes it possible to control three output channels with two deflection elements.
  • each deflection element is assigned its own solenoid drive, which must be controlled in a coordinated manner.
  • the control of the deflection elements is also complex, since the actuation of the two individual drives must be carefully coordinated. In the event of a malfunction, incorrect position constellations are possible.
  • the construction according to the invention allows an actuator to be used by using one adjustment direction for adjusting one deflection element and the other adjustment direction for adjusting the other deflection element from the respective basic position.
  • the only actuator and the means for coupling the deflection elements can be designed to be very compact.
  • both deflection elements are also forcibly coupled to one another via the common actuator, so that mutual incorrect positions cannot occur.
  • three output channels can be released in a space-saving manner immediately downstream of the printing station.
  • This offers the possibility, for example, of outputting an endless web not only to the rear of the printer, but also to the front of the printer, while the single sheets are fed into a storage compartment through an upwardly directed output channel.
  • the output of the single sheets does not have to be upwards either.
  • the deflection elements are reset in that the deflection elements are prestressed into their position which releases the first output channel, so that they return to this position when the drive device is reset to its starting position.
  • the drive device is formed, for example, by a stepper motor which is connected to a programmable controller.
  • the deflection elements are driven in such a way that a toothed segment is rotatably mounted on the axes of the deflection elements and is in drive connection with the drive pinion of the stepper motor via a gear such that the toothed segments can be driven in the same direction when the drive pinion rotates are, and that the deflecting elements are each coupled to the toothed segments via a slot-and-tenon connection in the pivoting direction, the deflecting elements being biased in opposite directions of rotation. Since in the embodiment described above the deflecting elements are biased in the opposite pivoting direction, they are for coupling between the Deflection elements and the tooth segments provided on opposite ends of the elongated holes assigned to them.
  • the feed device for the endless web is expediently formed by a push tractor which is arranged in the transport direction in front of the printing station and which can be switched over in its transport direction. If you want to switch from printing on continuous webs to printing on single sheets, the continuous web does not need to be pulled out of the device. It is sufficient to switch the push tractor so that the endless web is pulled out of the printing station so far that the single sheets can be fed to the printing station. If an endless web is required again, the push tractor is operated again in the normal transport direction so that the endless web can be fed to the printing station.
  • control of the deflection elements is expediently coupled to the control of the feed devices for the recording media, so that the associated output channels are also released when certain recording media are requested.
  • FIG. 1 shows a printer, generally designated 10, with a printing roller 12 and a matrix printhead 14.
  • the printing roller 12 rotates counterclockwise, so that the printed recording media upwards the printing station formed by the printing roller 12 and the printhead 14 leave.
  • An in front of the pressure roller 12 is used to feed an endless web 16
  • Push tractor 18 of conventional design which pulls the continuous web 16 into the printer 10 and pushes it through the printing station.
  • a deflection device generally designated 20
  • the endless web 16 can leave towards the rear or towards the front of the printer 10.
  • two single sheet magazines 22, 24 are arranged above the printer, each of which is assigned a schematically indicated removal and feeding device 26 or 28, withdrawn from the magazines 22, 24 via the single sheets and from the printing roller from above 12 can be supplied, as indicated by the dashed line 30 shown in Figure 1.
  • the single sheets leaving the printing station are output upwards by the deflection device 20 and stored in a storage compartment 34 above the printer 10 by a transport device 32.
  • the deflection device comprises two deflection elements 36 and 38.
  • the deflection element 36 is formed by an elongated curved plate which extends essentially over the entire width of the transport path for the recording media. Near its one longitudinal edge, the deflection element 36 is mounted in a frame 42 indicated in FIG. 7 so that it can pivot about an axis 40 running parallel to its longitudinal direction.
  • the deflection element 38 is likewise formed by an elongate plate which extends over the entire width of the transport path for the recording media and is supported in the frame 42 by means of shaft journals 44 about an axis of rotation oriented parallel to its longitudinal direction.
  • Both deflecting elements have ribs 46 and 48 on at least one of their sides, which serve to guide the recording media passing the deflecting elements.
  • the two deflection elements 36 and 38 are arranged directly above the printing station in such a way that they can control three different output channels depending on their respective pivot position.
  • the position of the two deflecting elements 36 and 38 is selected such that the recording media coming from the printing station are transported upwards between the two deflecting elements 36 and 38 into the single sheet storage compartment 34.
  • FIG. 4 shows the deflection elements 36 and 38 in a position in which an endless web coming from the printing station is deflected between the deflection element 38 and a stationary guide surface 50 of the printer 10.
  • an endless path is deflected between the deflecting element 36 and a stationary guide surface 52 towards the rear side of the printer 10.
  • a toothed segment 54 and 56 is rotatably mounted relative to the respective deflection element 36, 38.
  • the toothed segments 54 and 56 are coupled in the direction of rotation to the respective deflecting element 36 or 38 in such a way that a bolt 58 or 60 arranged at the longitudinal end of the respective deflecting element 36, 38 and oriented parallel to the direction of the axes 40 or 44 in one Elongated hole 62 or 64 engages in the associated toothed segment 54 or 56.
  • the toothed segment 54 stands over a double gear 66 and an intermediate gear 68 with the drive pinion 70 of a stepper motor 72 in drive connection.
  • the toothed segment 56 is in turn connected to the pinion of the stepping motor 72 via a double toothed wheel 74, an intermediate toothed wheel 76 and the toothed wheels 66 and 68. If the pinion 70 of the stepper motor 72 rotates, the toothed segments 54 and 56 are driven in the same direction due to the gear train selected.
  • the two deflection elements 36 and 38 are biased in the opposite direction of rotation by a tension spring 78 arranged between them, so that they assume the basic position shown in FIGS. 1, 6 and 7, in which the output channel between them is released.
  • This position of the deflection elements is defined by the respective stop of the bolt 58 or 60 at one end of the associated elongated hole 62 or 64. If the stepper motor 72 is now driven in such a way that the toothed segment 54 is rotated counterclockwise from the position shown by the solid lines to the position shown by the broken lines, the toothed segment 54 takes the deflection element 36 over the bolt 58, so that the deflection element 36 assumes the position shown in FIG. 5.
  • the control for the stepper motor is selected so that when the deflection elements 36, 38 are adjusted from a position different from the basic position, the basic position is first approached and then the desired position is assumed from there.
  • the adjustment paths required for this for the individual positions of the deflection elements are fixed in a memory of the control of the stepper motor and can be called up accordingly.
  • the deflection element 36 In its basic position, the deflection element 36 actuates a microswitch 82 with a stop 80, which generates a signal corresponding to the basic position, so that the stepper motor receives information about the actual state of the deflection elements.
