Definitions
- the invention relates to a device for turning and moving a web of continuous recording material, in particular a paper web in an electrographic printer. Furthermore, the invention relates to a device in which the Web of continuous recording material only parallel is transferred.
- Such devices are important components of a electrographic printing device for printing on band-shaped Record carriers of different bandwidth.
- a such a printing device is for example in WO / 94 27193 described.
- the printing device has an electrographic working intermediate carrier, for example a photoconductor drum, with a usable width corresponding to double Width format of a standard form, e.g. DIN A4 or letter-size format.
- the other aggregates like the Fuser, developer station, cleaning station, etc. are also designed for this usable width.
- Simplex mode will be used and parallel simplex operation.
- Simplex operation becomes a record carrier with up to twice the width of a DIN A4 sheet or a sheet with Letter-size format printed in conventional form.
- parallel simplex operation two separate lanes, e.g. each with a width according to A4 or letter-size format, juxtaposed by the printing device led and printed.
- the parallel in the printer offset or offset in parallel and additionally turned and fed to the transfer location of the printing unit and printed it must be ensured that the parallel movement or the parallel movement with simultaneous turning without any problems and runs with high precision.
- the web transport speeds Measures are achieved in the range of 0.1 to 2.5 m / s to provide for a fast run of the web Use of foldable endless material with folds enable.
- this web in which the web is turned and is displaced, this web becomes loose around a deflection device led around with the first edge from the top fed obliquely downwards to the deflection device and there coming from below is discharged diagonally upwards.
- the edge lies on the first guide surface of the deflection device so that a natural loop formation of the web feed device forms up to the web delivery device. Because this first edge is loose on the first guide surface the web loop can be in the vertical direction Execute deflection movements and thus fluctuations in the transport speed compensate in the area of the deflection device. Such fluctuations can e.g. by changing the Frictions or wrinkles.
- the Invention is both for webs of continuous material without cross running folds as well as for sheets with folds (fan-fold sheets) suitable.
- the web surface comes with only a few Elements in frictional contact. This eliminates the risk of railway congestion due to different friction conditions or injury to the web is reduced.
- the in contact with the The surfaces of the mechanical guides that are in contact with the surface can very low-friction surfaces or by surface treatment be designed to be wear-resistant. Operational security the facility is thereby further increased.
- the first guide surface is preferably convex. she is thus due to the curvature caused by the weight of the web and its elasticity, self-forming geometry of the web loop adapted and supports the natural formation of loops.
- An embodiment of the invention is characterized in that that the elongated body of the deflection device in its upper area has a second guide surface, which the first edge opposite second edge of the web leads and stops when the orbit wraps up around the body rises and exceeds a predetermined height.
- the vertical deflection movement of the loop will take measures Loop base limited to a predetermined size. If due to a disturbance the regularity of the rail transport is disturbed, for example by buckling the web to the Folds of a fan-fold web, so the web loop is shortened, what happens in a climb up the train at the first Leadership area. The top, second edge of the web comes to the second from a predetermined height Guide surface, whereupon the tension on the second edge of the Web is enlarged and the web tightens and unfolds. Disruptions in the passage of the web are thus automatically balanced.
- the height of the first and second guide surfaces can be adjusted.
- the deflection device can be attached to different Widths of the web can be adjusted.
- the height adjustment enables adjustment to the length the web loop from web feed device to web delivery device.
- This web loop also serves as a web storage, its length depends on the length format of the sheets used the web and set by the printer controller or is given to the operating personnel.
- a device for moving a web of continuous recording material provided with the features of claim 12. With this facility, the web is not turned.
- the Device is designed so that the web is hanging loosely Web loop forms.
- the track is run so that the web delivery device facing the first edge of the fed web on the web feed device facing away Side along a second transport path approximately in the direction of transport is removed.
- the top side the lane on the second transport lane and the top of the Path on the first transport path match. This Setup is therefore for two-tone simplex operation used.
- the solution of the task according to this aspect of Invention is surprisingly simple and is based on the Weight force of the web naturally forming web loop enables the offset by at least one web width. Because of the weight of the web remains the web loop high transport speed stable in shape. It can both sheets with folds and smooth sheets transported and moved.
- the web removal device is at least approximately in a horizontal element arranged with a guide surface over which the web passes after passing through the Web loop is guided, the longitudinal axis of the guide surface with the longitudinal axis projected into the horizontal plane the web feed device an angle in the range of Includes 15 ° to 25 °, preferably 20 °.
- This guide element allows through its oblique arrangement that the natural loop shape is preserved and small radii of curvature when diverting into the parallel transport path, which can cause wrinkles to be avoided become.
- the guide element causes the web to buckle Folding prevented.
- About wrinkling or wrinkling in the recording material to avoid, is the one leaving the guide elements Web fed directly to a deflection element from below, which deflects the web in the direction of the web loop.
- the deflecting element has a longitudinal axis that is at least approximately parallel to the longitudinal axis of the web feed device. The deflecting element prevents curvature of the web, which is due to the displacement of the web by at least one web width can.
- the guide element and preferably also the deflection element on the web feed device facing side each have a stop on which there is an edge of the web. This results in printing defined edge positions of the web and precise guidance.
