Definitions
- the invention relates to a device for printing, in particular a Franking and / or addressing machine, with a print head that can be moved is held on a printhead holder.
- the printhead bracket is to achieve the relative movement between printhead and medium to be printed when printing along a first direction with respect to a base element between a first longitudinal position and a second longitudinal position designed to be movable. Still is one offset the printing to one another transversely to the first direction
- First transfer device enabling printing images is provided. This is used to move the printhead relative to the printhead bracket from a first transverse position in at least one of the first transverse position second transverse position spaced apart from the first direction.
- the first displacement device comprises at least one first guide device with a first guide surface and at least a second guide device with a guide element, those for moving the print head from the first to the second transverse position by moving the printhead holder along the first Direction interact under mutual relative movement.
- the term “print head” denotes all types of printing devices that have a printed image on a medium can generate. In other words, the term closes on the one hand Printing facilities of any printing techniques. He shouldn't either be limited to the component that directly generates the printed image, but can also include other components that are used to generate printed images are needed. Ink reservoirs, for example etc.
- a generic device is for example from the EP 0 980 761 A1 is known.
- the print head slidably in a guided by a guide rod Bracket arranged.
- the holder For printing, the holder and so that the print head along a first direction, namely parallel to Move the guide rod.
- the print head becomes perpendicular to offset in the first direction relative to the bracket in a further Step a second print image using the opposite method of Generate printhead along a first direction.
- the offset of the second printed image to the first printed image is so large that the two printed images overlap at most in the edge area, in which they are adjacent to each other across the first direction. This is it is possible to generate an overall print image with one print head, its dimension transverse to the first direction, d. H. across the printing direction, corresponds approximately to twice the print width of the print head.
- the displacement device is in the known device by a on the underside of the printhead arranged pin realized to Moving the print head transversely to the first direction in a groove in the base element is led.
- the groove is inclined to the first direction, so that with a relative movement between the pin and groove along the first direction the offset movement of the printhead perpendicular to first direction is generated.
- this design has the disadvantage that the groove is relatively complex to manufacture, since particularly tight tolerances are observed have to be exactly to the desired cross offset achieve. Another disadvantage is that subsequent adjustment is next to impossible.
- the present invention is therefore based on the object Generic device and a generic method to indicate that with little effort a fast, high quality Allows printing.
- This task is based on a device according to the Preamble of claim 1 by the in the characterizing part of Features specified claim 1 solved.
- the invention is based on the technical teaching that one is special inexpensive and easy to implement device for Printing receives when the guide element of the second guide device is arranged on the base element.
- One at the base element arranged guide element can be clearly seen easier to manufacture than the known guide groove.
- the guide element it is possible in a simple manner, the guide element to adjust later.
- it can be perpendicular to the first Direction adjustable on the base element.
- the second guide device it is possible for the second guide device to achieve the position adjustment to train in the manner of an eccentric.
- a guide pin with a circular cylindrical active surface around an eccentric horizontal axis be rotatably attached.
- guiding device in the sense of the present invention includes any facility that interacts with a Counterpart as the guide element according to the invention the direction the relative movement between the guide device and the Influence counterpart.
- the first guide device acts on the print head. She can be arranged directly on the print head for this purpose. Alternatively, you can they can also be arranged on the printhead holder and via appropriate Active elements for moving the print head act on it.
- the first guide device has at least one first guide surface on and the second guide device is of a guide element formed with the first guide surface for moving the print head cooperates.
- the first guiding surface is when interacting of the guide devices from the guide element swept over.
- the guide element can have a second guide surface have the interaction of the management facilities is swept over by the active partner.
- the guide element is designed so that a Line or point contact with the first guide surface results.
- the contact i.e. H. the action of a contact force between the two management facilities is ensured is also a defined one Movement of the print head guaranteed when moving.
- the contact force can be ensured, for example, by a spring, which acts on the printhead.
- the first guide device is preferably of a guide groove and the second guide device is formed by a guide pin, since this is a particularly easy to manufacture configuration with reliable leadership results.
- such a configuration guaranteed forced operation which also without separate Biasing the two guide devices against each other enables reliable guidance.
- the first guide surface is inclined to the first direction.
- the slope course the first guide surface, in particular the guide groove to the first direction can also the course of the contact force be adapted between the management facilities. This can change especially in the case of variants via the offset movement, at which a bias of the two guide devices against each other is provided by a spring or the like, which with progressive Cross offset of the printhead is always deformed and therefore a changing contact force between the two guiding devices causes.
- the inclination can be adjusted accordingly take place that certain normal and / or tangential force limits not in the contact area of the two management facilities be crossed, be exceeded, be passed. This can lead to wear of the guide devices be kept low.
- the guide groove is substantially V-shaped or Y-shaped Course on. This enables while the printhead is being moved a movement reversal across the first direction along the first Direction. This reduces the effects of this reversal of movement on the offset accuracy. This can be done against the background of the fastest possible printing process Passing through the offset area due to a jerky reversal of movement occur. By following this design leadership that is still guaranteed in the reversal of movement is such Influences reduced to a minimum. Incidentally, it goes without saying that the legs of the guide groove are not necessarily straight must be carried out. You can also have a curved course exhibit.
- the legs of the V-shaped or Y-shaped guide groove are preferred arranged inclined to the first direction. This reduces the travel path required for the transverse offset Printhead bracket along the first direction, which in turn has an advantageous effect on the size of the device. Run preferentially Leg of the guide groove essentially symmetrical to one axis essentially parallel to the first direction, since here given the inclination of the legs to the first direction, the shortest travel required for the transverse offset is achieved.
- a guide device is then in the transition region of the legs of the guide groove to ensure the offset movement from the first in the second transverse position is provided.
- This is designed so that Guide element after the reversal of movement the one not yet passed Area of the guide groove. This makes it reliable excluded that after the reversal of movement an unintentional Reset to the starting position is done by not the other The course of the guide groove is traversed, but the one just traversed Area of the guide groove again, but now in the opposite Direction.
- the guide device preferably comprises a switch device, to close the first leg of the guide groove and release of the second leg of the guide groove after passing through the Switch device is formed.
- the guide device arranged on the base element is preferred the first displacement device in the area of the first or second Longitudinal position of the printhead bracket arranged to offset the cross the print head immediately after reaching the first or second Allow longitudinal position of the print head holder. So that is ensures the smallest possible size of the device. Secondly, due to the short distance to be driven through Also the total printing time.
- the device according to the invention is at least a second displacement device for displacing the Printhead provided from the second to the first transverse position. This enables the device to be operated in a circular manner, i. H. it must not the first to reach the printhead home position Be moved in the opposite direction.
- the second displacement device can be of a simple spring and one Trigger device can be formed, which the print head in the first Transverse position, d. H. its starting position transverse to the first direction resets after actuation of the release device.
- the second displacement device for displacing the Printhead from the second to the first transverse position by moving the printhead holder is formed along the first direction, whereby a separate drive is also unnecessary here.
- the second transfer device works for low-cost further training on the same principle as the first transfer device.
- the second displacement device comprises at least a third Management facility.
- This third guide device is further preferred for cooperation with at least one of the guide devices the first transfer device so that the provision of a separate with the third guide device cooperating management device is unnecessary.
- a guide device is the first displacement device in the area of the first longitudinal position of the printhead holder arranged on the base element and the third guide device is in the area of the second longitudinal position of the printhead holder arranged on the base element.
- the first displacement device in the region of the second longitudinal position the printhead holder is arranged on the base element and the third guide device is in the area of the first longitudinal position the printhead holder is arranged on the base element.
- the configuration according to the invention on the one hand makes a separate one Drive for transverse displacement of the printhead saved. Instead the drive becomes the movement of the print head during printing also used as a drive for the transfer device.
