Definitions
- a refill cartridge comprising a box for removably housing the
- Ink jet printheads are commonly used in various printing devices, in
- each printhead is movable with respect to a print line.
- An example of these printheads is described in the US Patent No. 5,119,115.
- each printhead is
- the cover is provided with a tube
- the tank of the printhead is put in communication with the ink contained in the cartridge, for causing the ink to pass through the tube from the cartridge to the tank, so as to refill the printhead.
- the purpose of this invention is to obtain a holder for refilling an ink jet printhead that is easier and more practical to use than those known in the state of the art described above.
- a holder which comprises a first cover suitable of assuming a locking position on the box for positioning and locking the printhead into the box, a second cover, and a tube mounted on the second cover and having a first end for entering into the refill cartridge for allowing the passage of ink from the latter to the
- the first cover is pivotably mounted on the box and is rotatable from a rest
- a further purpose of the invention is to provide a holder for refilling an ink
- jet printhead which is adapted not only for refilling the printhead, but also for
- the second embodiment is provided for avoiding some drawbacks of the first embodiment which render the latter not adapted for
- the tank in the head is no longer assured, and moreover in that if, in an attempt to avoid the tube penetrating the head, the cover is not fully closed on
- the holder is characterized by a
- Fig. 1 is a lateral cross-sectional view of a first embodiment of a holder
- Fig. 2 is the holder of Fig. 1 in an operating position.
- Fig. 3 is a partial, lateral cross-sectional view and in an enlarged scale
- Fig. 4 is the holder of Fig. 3, when it is in a second working position.
- a holder 10 for an ink jet printhead 11 With reference to Fig. 1, a holder 10 for an ink jet printhead 11 ,
- the box 21 has a
- the covers 22 and 23 are pivoted, by means of a
- hinge 24 on parts 51 projecting upwardly from two sides 53.
- the hinge 24 defines a pivoting axis which is the same for the covers 22 and 23.
- the first cover 22 can be selectively rotated with respect to the box 21
- the second cover 23 is rotatable independently from the first cover 22 with respect to the box 21 and can be superimposed to the first cover 22, in
- the printhead 11 is shown schematically with a broken, dotted line and
- a body 12 has a body 12, an internal tank for containing ink, a lower face bearing nozzles 14 for emission of the ink and an upper face in which a hole 17 is
- the hole 17 has the scope of maintaining the ink contained in the tank at a predetermined pressure with respect to the external atmospheric
- a refill hole 18 normally is provided on the upper face, which refill hole 18 is in communication with the tank inside the printhead 11 for allowing the refilling of the tank with fresh ink, as will be described later.
- One side 53 of the box 21 is provided with a vertically-oriented aperture
- the first cover 22 has a lower edge having a shape which substantially
- the first cover 22 is
- both first cover 22 and second cover 23 are provided with a tooth 26
- tabs 25 are perfectly aligned and permit a quick, easy and selective unhooking
- a rubber element 27 Arranged on the cover 22 is a rubber element 27 which, when the
- printhead 11 is housed in the box 21 and the cover 22 is rotated in its locking
- the second cover 23 is shaped as a dome having upwardly a seat 30
- the cartridge 34 is represented schematically with a broken, dotted line.
- a straight and short tube 31 is fixly mounted to the cover 23 and passes through the latter for extending outwards from opposite sides of the cover 23.
- the tube 31 has two ends 32 and 33, which protrude respectively into the seat
- the seat 30 is open towards the outside of the holder 10 to receive the tip 35 of the cartridge 34.
- the end 33 of tube 31 has a flat shape and is operable for removing a closing element which obstructs the refill hole 18, so allowing the end 33 itself to pass through the hole 18 and to enter the tank of the printhead.
- the end 32 of tube 31 is tapered so as to be able to perforate the tip 35 which is of a resilient material.
- the ink inside the cartridge 34 is put in communication with the tank in the printhead 11.
- the ink in the cartridge 34 can thus pass through the tube 31 and refill the tank into the printhead 11, either for the effect of gravity and/or of a slight depressure inside the tank.
- the box 21 has in its cavity 50 a bottom 40 in which two rubber caps 41
- a first rubber cap 41 has substantially the scope of abutting against the nozzles 14 so as to seal them during refilling of the printhead 11, while the second rubber cap 42 is provided for operating as a further, resilient support of the lower face of the printhead 11 , when the latter
- the rubber caps 41 and 42 are supported by corresponding springs 43, which are arranged between the same rubber caps 41 and 42 and the bottom 40.
- the springs 43 are subject to yield when the
- printhead 11 is pushed towards the bottom 40 by the ribs 54 of the first cover
- yielding happens in correspondence of the final portion of the rotation of the first cover 22 for reaching its locking position and is activated by the entering
- inventive concept applied by this first embodiment can serve to define other embodiments of the holder 10.
- one only of the covers 22 and 23 may be pivoted on the box 21 , whilst the other cover may be
- the other cover may be linked to that one only cover in a way different from pivoting, for example, the other cover may be detachable for being completely removed from the box 21 each
- the holder of the second embodiment is indicated with 20 and comprises, similarly to the first embodiment, a box 121
- the covers 122 and 123 are capable of being selectively rotated with
- sealing element 65 For purpose of refilling it with ink, and is normally sealed by a sealing element 65,
- the cover 123 is dome-shaped and thus, when closed on the box 121 , creates a volume around the printhead seated in the holder, substantially
- upper cover 123 is a sliding element 60, which slides on the cover 123 and attached to which is a tube 131 having a first end 132 and a second end 133.
- the sliding element 60 is provided with a seat 130 for receiving the
- the seat 130 has guide elements 66 and is adapted for receiving
- the sliding element 60 is suitable for sliding on a guide 61 of the cover
- Each tooth 62 is so shaped as to form an
- the method of operation of the device is as follows. Firstly, after the
- box 121 for use immediately in printing, or may be left in the holder 20 for preservation purposes, in which case the cover 123 is again closed over the
