Definitions

  • Inkjet printer with holder for a printing ink tank
  • the invention relates to an inkjet printer according to the preamble of claim 1.
  • the swap body In such an ink jet printer, the swap body is in an operative position when inserted into the holder and connected to the printhead so that ink is directed from the swap body to the printhead.
  • the swap body For many requirements, the swap body must be able to be put into the operational position in the shortest possible time and also by an inexperienced operator of the printer, for example when operating a cash register printer.
  • an inkjet printer of the type mentioned at the outset is known, for example, from DE 43 30 798 AI.
  • the swap body designed in the form of a rectangular ink cartridge is inserted into a compartment connected to the printing carriage.
  • a bow-shaped lever is mounted on two opposing compartment walls with two parallel arms, which are connected to each other by a crossbar.
  • curved guide grooves are formed about the lever pivot axis, the distance from the lever pivot axis changes.
  • a pin provided on one side wall of the ink cartridge engages in each of these guide grooves.
  • the arrangement is such that the ink cartridge inserted into the compartment is moved from the initial loading position into the operating position by pivoting the bow-shaped lever, in which the line element pierces a seal of the ink cartridge and thus connects the interior of the ink cartridge to the printhead.
  • This solution requires a dimensionally stable ink cartridge with relatively precisely arranged pins in order to be able to move the ink cartridge from the loading position into the operating position via the bow-shaped lever.
  • An inkjet printer is known from EP 0 854 046 A2, in which an ink cartridge can be inserted into a compartment of a pivoting lid, said ink cartridge consisting of a stable cuboid housing and a tubular ink container arranged therein.
  • the housing has an opening through which a ground end of the line element arranged on the shelf can penetrate.
  • the invention has for its object to provide an ink jet printer of the type described in the preamble of claim 1, in which the swap body can be quickly and easily brought into its operational position and replaced, but simple in construction and inexpensive to manufacture can be.
  • the swap body only needs to have a simple wall and only needs to be adapted in terms of its volume to the size of the drawer that receives it. Nevertheless, a precise adjustment of the swap body between the loading position and the operating position is ensured by the drawer guided in the frame.
  • the swap body In the loading position, the swap body is not connected to the printhead and can therefore be easily inserted the holding device inserted or removed from this. After inserting the swap body into the loading device, the swap body is automatically put into its operating position when the insertion mechanism is subsequently actuated. If an empty swap body is to be removed from the holding device, it is automatically moved from the operating position back into the loading position by the insertion mechanism.
  • the insertion mechanism comprises a locking lever which can be pivoted about an axis of rotation fixed to the frame and which has at least one arcuate curved guide slot on at least one side surface transverse to its axis of rotation, the two ends of which have different distances from the axis of rotation, one in the guide slot on the drawer engaging pin is arranged so that it strikes when the locking lever is open at the end of the guide slot remote from the axis of rotation and when the locking lever is closed at the end of the guide slot near the axis of rotation.
  • the drawer and thus also the swap body can be adjusted precisely and without great effort by simply pivoting the locking lever.
  • the frame of the holding device in which the drawer is displaceably arranged, is pivotably mounted about an axis of rotation which is transverse to the direction of movement of the drawer.
  • This has a guide slot on a side wall parallel to its direction of movement, into which a guide pin engages, which is formed on a part of the holder which is fixed relative to the frame and the drawer, the course of the guide slot being one with respect to the direction of movement of the Drawer has a parallel component and a component perpendicular to it.
  • an electrical control circuit is provided with a switching element arranged on the holding device and biased into an open position, in which the switching element is arranged on the same side of the holding device is like the cable element and protrudes from this side towards the drawer.
  • the control circuit can, for example, generate a signal which actuates a device for locking the printer when the swap body has not been put into its operating position. In this way, the inkjet printer can be protected from improper use.
  • FIG. 1 shows a schematic longitudinal section through a holding device according to the invention for a swap body according to a first embodiment of the invention with the insertion mechanism in the loading position
  • FIG. 2 shows a schematic longitudinal section through a second embodiment of a holding device according to the invention.
  • Figure 1 shows a holding device 10 for an interchangeable container for use in an inkjet printer.
  • the holding device 10 has - seen in longitudinal section - cuboid and open on its top frame 12.
  • a drawer 14 is arranged so that it can be moved in the direction of the double arrow 16.
  • the drawer 14 has an insertion opening 18 for receiving an interchangeable container 20 for printing ink.
  • a closing lever 22 is arranged which is rotatably mounted about an axis of rotation 24 fastened to the frame 12.
  • the axis of rotation 24 of the locking lever 22 is directed horizontally and transversely to the direction of movement 16 of the drawer 14.
  • Figure 1 shows the locking lever 22 in an open position in which it extends vertically upward. The position corresponds to a loading position in which the interchangeable container 20 can be inserted into and removed from the drawer 14.
  • the locking lever has a U-profile with a long side 26 extending transversely to the direction of insertion 16 and a rectangular transverse side 28 directed parallel to the plane of the drawing, which widens at its lower end in the form of an arc 30 circumscribing the axis of rotation 24.
  • a guide slot 32 is formed, which runs essentially parallel to the arcuate edge 30.
  • the guide slot 32 has an end close to the axis of rotation 24 and one of end of the axis of rotation.
  • the near end of the guide slot 32 lies above the axis of rotation 24 and with it - viewed in the direction of insertion 16 - at the same height.
  • a guide pin 34 is arranged which engages in the guide slot 32 in such a way that, in the open position of the locking lever 22, it bears against the end of the guide slot 32 remote from the axis of rotation 24 .
  • the guide pin 34 can also be arranged on the interchangeable container 20 itself.
  • An opening 38 is formed on a left side wall 36 of the frame 12 in FIG. 1, which receives a stopper 40.
  • the plug 40 has a bore 42 in its center, in which a hollow needle 44 is inserted.
  • the hollow needle 44 has a tip 46 pointing towards the drawer 14 with an opening 48.
  • the hollow needle 44 protrudes outwards from the left side wall 36 of the frame 12. Here it is enclosed by one end of a hose 50, which connects it to a print head (not shown) of the inkjet printer.
  • a guide pin 52 extends on the left side wall 36 of the frame 12 parallel to the hollow needle 44 in the direction of the drawer 14.
  • the drawer 14 has on its left side wall 54 a first engagement opening 56 aligned with the hollow needle 44 and a second engagement opening 58 aligned with the guide pin 52.
  • an elongated hole 60 extending in the direction of movement 16 is formed in the bottom 62 of the drawer 14 near its left side wall 54.
  • a switching lever 68 of an electrical switching element 70 which is pretensioned into an open position and is arranged on the bottom 66.
  • the swap body 20 has on its left side wall 72 an opening 74 into which a valve 76 for the engagement of the hollow needle 44 is inserted.
  • a cylindrical recess 78 in the left side wall 72 serves for the engagement of the guide pin 52 when the swap body 20 is adjusted into the operating position.
  • the closing lever 22 is pivoted clockwise about its axis of rotation 24 as shown in FIG.
  • a force acting in the direction of movement 16 is exerted on the drawer 14 or the swap body 20 via the guide pin 34, so that the swap body 20 and the drawer 14 together in FIG can be moved to the left.
  • the hollow needle engages through the valve 76 in the interchangeable container 20 and thus establishes a connection between the printing ink supply in the interchangeable container 20 and the printhead of the inkjet printer.
  • the drawer 14 slides over the switching lever 68 and thereby presses it downward against the spring force, whereby the electrical switching element 70 is actuated to signal that the swap body 20 has reached its operating position.
  • Figure 2 shows an alternative embodiment of the holding device according to the invention.
  • the parts corresponding to the holding device of the first embodiment have the same reference numerals and will not be explained again.
  • the holding device 80 is almost identical in construction to the holding device 10 except for the following essential differences.
  • the holding device 80 has no closing lever 22 for realizing the insertion mechanism. Instead, the frame 12 as a whole is pivotally mounted about an axis of rotation 82.
  • the axis of rotation 82 extends transversely to the direction of movement 16 of the drawer 14 when the interchangeable container 20 is inserted into the operating position and is mounted on a chassis of the inkjet printer, not shown.
  • the axis of rotation 82 is located below the frame 12 and close to its left side wall 36.
  • a guide slot 86 is formed, into which a guide pin 88 engages, which is arranged in a fixed position on a chassis-fixed part and by a grips a suitable opening in the frame 12.
  • the contour of the guide slot 86 has a component parallel to the direction of movement of the drawer 14 and a component perpendicular to it.
  • the upper end of the guide slot is thus a greater distance from the left side wall 36 of the frame than its lower end.
  • the guide pin 88 is located in the loading position shown at the lower end of the guide slot 86.
  • the frame 12 in FIG. 2 is pivoted clockwise about its axis of rotation 82 until it reaches the operating position indicated by dashed lines 90.
  • a force acting to the left in the direction of movement 16 is exerted on the drawer 14 or the swap body 20 via the guide pin 88, so that the swap body 20 and the drawer 14 are adjusted together in the direction of movement 16.
  • the hollow needle 44 engages through the valve 76 in the interchangeable container 20 and thus establishes a connection between the printing ink device in the interchangeable container 20 and the print head of the inkjet printer, as has already been explained above.
