Definitions
- the invention relates to a printing press according to the preamble of claim 1.
- a printing press of the generic type is on the same applicant declining DE-A1-41 39 891 known.
- a medium to be printed e.g. Labels
- a medium to be printed is between a counter pressure roller and a Thermal print head passed through with a parallel row running individually to the axis of the counter pressure roller electrically controllable heating elements is provided to the medium in the thermal or thermal transfer process print.
- the thermal print head is on a so-called Support attached, which in turn via a compression spring communicates with a spring base.
- the latter is - as well as the support - rotatable on a bearing pin stored.
- the angle of the spring base on the bearing pin is the Tension of the compression spring and thus the contact pressure of the Supports and the thermal print head on the Counter pressure roller set.
- the angle of the floor is through a mechanical connection - a wedge between the free end face of the bearing pin and the Spring base defined.
- a locking member is used in DE-A1-43 32 602 a keyhole-like breakthrough that also a connection between the free end face of the spring base and the bearing pin.
- a disadvantage is that the bearing pin is relatively heavily used on torsion since it is a by the pressure of the print head on the Counter pressure roller arising due to the large lever arm and the not inconsiderable pressure forces quite high Torque from its free to be with the frame of the Printing machine connected end must transmit. Of the Bearing pin is therefore used to implement a appropriate torsional stiffness (and print quality) relatively thick, heavy and expensive to size.
- the object of the present invention is that To simplify the structure of the known printing presses and while maintaining perfect print quality Make manufacturing cheaper.
- the object is achieved by a Locking device for locking the spring base, which with the Frame connected and at a distance from the bearing pin with the Spring base is connectable.
- the main idea is the azimuthal locking the spring floor by a separate sash realize that caused by the compression spring Torque independent of the bearing pin from the spring base the frame transmits.
- the bearing pin is only used for Storage of the spring base - and if necessary the support - and is no longer twisted, so that no unwanted Deformations are to be feared.
- the main advantages of the invention are that the bearing pin due to the reduced Torsional stress with constant accuracy Alignment of the printhead relative to the platen and thus equally good print quality less stable and can therefore be chosen cheaper.
- the sash turnable on the frame to fix he can choose between a first position, in which he is connected to the spring base and a second Position in which the printhead is open swiveled will.
- the axis of rotation of the Sash preferably parallel to the axis of the Counter pressure roller; the latter therefore extends in one orthogonal to the counter pressure roller and the bearing pin trending level, usually sufficient space is available for a pivoting movement.
- the contact pressure of the support on the counter pressure roller among other things even after the print medium.
- a thicker one and more rigid medium requires a higher contact pressure than a thinner, more flexible one.
- the edge of the tappet with the bulges like this is shaped that the pin by rotation of the sash can be successively snapped into the various indentations is.
- the distance between the sash's axis of rotation and the boundaries of the sash, on which the pen for Concerns, has (as a function of the angle of rotation of the Local maxima in the bulges - the pin snaps there due to the force of the compression spring one - and is opposite between the bulges reduced so that the compression spring when turning the Cam is compressed.
- the tamper offers itself to be designed so that it is open - but in the Usually manually pressed against the counter pressure roller - Printhead with a corresponding rotation first its with the bulge (or bulges) the border on the pin.
- This Border is now beveled so that at one further rotation of the sash the distance between its axis of rotation and the pin continuously decreased; the compression spring is compressed further and further until the Pin engages in a bulge.
- the opening of the Printhead becomes analog by turning the cam realized in the opposite direction.
- the Distance between the border with the bulges and the axis of rotation of the sash for example, linearly with the angle of rotation decrease or the boundary can be in this Area in the manner of an eccentric or spiral eccentric be shaped.
- the Locking device can be pivoted and adjusted via an eccentric be attached to the frame.
- the strut can be on the sash or in the distance of which are rotatably attached to the frame. Besides, is conceivable, the strut and the sash on one axis to be rotatable on the frame or the fastener on the Fix strut.
- the one locked on the spring base Support the cam in the azimuthal direction on the strut, to prevent unwanted twisting. It says he at a distance from his axis of rotation via a driver and an attached stop with the strut in the Contact. Should the tamper in different Positions must be lockable, of course, also Position of the stop can be varied. That can in concrete by repositioning a pin or repositioning a screw happen.
- a printing machine e.g. one Thermal printer, inkjet printer, etc.
- a Bearing pin 2 Parallel to its geometric Axis a counter pressure roller 9 is fixed on the frame.
- the print medium runs between it and a print head through that from a support 5 of the printhead to the Counter pressure roller 9 is pressed. With the print medium is the running run for example a roll of paper or a liner with labels.
- the printhead has a thermal printing board 7 with a Row of individually controllable heating elements 8, which are extends parallel to the axis of the counter-pressure roller 9 and on the lateral surface of the counter-pressure roller 9 in plant is held.
- the thermal printing board 7 is on the Bottom of the support 5 via an intermediate layer 6 e.g. made of aluminum.
- the thermal printing board 7 will in their manufacture with the intermediate layer 6 firmly connected, thereby increasing their strength.
- the electrical control of the heating elements 8 takes place via an electrical connector 10.
- the support 5 and a spring base 1 form together with a compression spring 11, the main components of the Printhead holder. Because in the position of use, as later is explained in more detail, the spring base 1 compared to the Frame 1 occupies a fixed position, presses the compression spring 11, which in the drawing as a helical compression spring is formed, the support 5 against the counter pressure roller 9. It is like a comparison of Figures 2 and 3 shows that the spring force is greater the closer it is left free end of the spring base 1 is located on the support 5.
- the spring base 1 has a sleeve-like extension 3, the length of which is approximately that of the bearing pin 2 corresponds. In this way, it is on the bearing pin 2 whose axis is rotatably mounted. The storage takes place however is not directly on the bearing pin 2, rather between the sleeve-like extension 3 and the bearing pin 2 another bearing sleeve 4 of the support 5 switched. Also their length corresponds essentially to that of Bearing pin 2. While the bearing sleeve 4 the bearing pin 2 to 360 °, i.e. fully enclosing, is the sleeve-like Approach 3 designed as a kind of longitudinally slotted sleeve. Both spring base 1 and support 5 are thus on the Bearing pin 2 rotatably mounted.
- Figure 1 shows the already known prior art reproduces
- Figure 2 Invention a sash 12 recognizable. He is at his lower end (at the opposite end of the printhead Side of the medium to be printed on the sufficient Space is available) in the sense of double arrow 20 about an axis running parallel to the counter pressure roller 9 16 rotatably connected to the frame.
- the forerunner 12 has a vertical in the drawing extending, longer body and on which the Rotational axis 16 opposite end face a relative head 15 angled to the main part by about 90 °; he is roughly hook-shaped.
- protruding pin 14 rests on the underside of the head 15, serves the latter for adjusting the azimuthal position of the Spring base 1 and defines the pressure force of the Printhead on the counter pressure roller 9.
- the distance between the axis of rotation 16 and that on the pin 14 adjacent point of the head 15 defines the angle of the Spring base 1 (as a function of the angle of rotation of the Fastener 12).
- the head 15 is in his - left in the drawing drawn - frontal area shaped so that its underside - i.e. the one with the recesses 13, 13 ' provided edge - the pin 14 at itself then closing the print head first by captured above.
- the closing force increases (i.e. the preload of the Compression spring 11) then gently but continuously on - there the distance between pin 14 and axis of rotation 16 decreases - until the pin 14 snaps into the recess 13.
- the distance between the axis of rotation 16 and the boundary of the Sash 12 which comes to rest on pin 14, drops So between the the outer end of the head 15 and the bulge 13 adjacent to it continuously.
- the free end of the Bearing pin 2 is smaller with a pin 18 Diameter provided. It serves to accommodate one hook-shaped end 19 of a strut 17, which in the sense of Double arrow 21 rotatable at the pivot point 16 of the sash 12th is hinged to the frame. This way you get instead of a flying storage one at both ends supported carrier, the perfect pressing of the Guaranteed pressure medium to the counter-pressure roller 9.
- the Strut 17 can by a pivoting movement in the Counterclockwise to an ineffective position be spent in the medium to be printed no longer spills over, for example inserting a ribbon or medium. It would be of course also conceivable, the hook-shaped end 19th the strut 17 to offset by 180 °, so that they are in Can be brought clockwise into its ineffective position is.
- the strut 17 also serves to fix the Camlock 12.
- the latter is about in the middle Area with an orthogonal to the main part (which is in the drawings extends approximately vertically)
- Driver 22 provided two holes for insertable stops (23, 23 ').
- the stop 23 located further to the left on the Aim for 17 while stop 23 is removed in Figure 3 (i.e. pulled out) and the second stop 23 'on the right edge of the strut 17 is present.
- the first (Left) stop 23 prevents in particular that too much pressure is accidentally set.
- a handy, fold-out handle 24 is through Hinges attached to the driver 22 of the sash 12; it makes handling easier.
