Description

The invention relates to a method for conveying a moving, in particular single-layer or multi-ply, material web of the paper-processing or cardboard-processing industry, wherein the material web is conveyed at a predetermined speed, preferably continuously. Furthermore, the invention relates to a device of the paper-processing or the cardboard-processing industry for conveying a moving, in particular single-layer or multi-ply, web of paper processing or carton processing industry, wherein the web is at a predetermined speed, preferably continuously conveyed.

In the paper or cardboard processing industry wide webs of paper, cardboard, plastic film or the like are supplied in one or more layers a slitter or a longitudinal cutting device, so that the wide Material webs are cut into several continuous webs. Subsequently, the longitudinally cut material webs are conveyed to a cross cutter or a cross-cutting device in order to cut the material webs into sheets. Subsequently, the sheets are fed to a collecting area, so that in the collecting area sheets of paper or the like are stacked in a stack and conveyed away.

For example, in DE-A-39 06 376 discloses a device for longitudinal cutting of continuous material webs, the device comprising upper knives and lower knives having existing rotating knives. In addition, in DE-A-43 21 860 Cross cutter or slitter for cutting a web described transversely or in the direction of their direction of movement.

Furthermore, it is off DE-A-30 07 692 describes a device for depositing sheets on a stacking point, wherein at the stacking point of the stacked sheets, a marking device is provided which, depending on a predetermined count, the sheet stack with a ream marking or the like.

Based on this prior art, the object of the invention is the identification of webs of paper processing or the cardboard processing industry to improve in a simple manner, the design effort for this is to be kept as low as possible and where it should be possible in particular to achieve a clear and separation-accurate marking in a stack.

This object is achieved in the method for conveying a moving, in particular single-layer or multi-ply, material web of the paper-processing or cardboard-processing industry, wherein the material web is conveyed at a predetermined speed, preferably continuously, in that the material web is curved in at least one lateral edge region by means of a, in particular non-color, mold and then that the side edge of the curved edge region of the material strip in, preferably a linear or linear, contact is made with a paint applicator, so that the side edge of the web is marked by means of the color provided by the paint applicator in a marking operation.

The invention is based on the idea of the side edge or side edges of a single or multi-ply web of paper or the like during conveying of the continuous, i.e. uninterrupted to mark the material web in color, whereby the color is applied exclusively to the side edge of the material web. For this purpose, the edge region is first deformed or curved by means of a molding tool with the side edge of the conveyed material web to be marked, so that the edge region of the material web protrudes from the plane of movement of the material web. In this case, no color is applied by means of the molding tool, since the mold is not formed color-leading or not color-transmitting.

Due to the curvature of the material web in engagement with the molding tool, a paint application member is introduced in a second step to the gap created thereby, wherein subsequently the effective engagement of the molding tool with the material web is released so that the side edge of the edge region of the material web bears against the paint application member. so that in contact between the side edge and the paint application member, the side edge of the web is provided with color, as under further promotion the material web is discharged laterally along the Farbauftragungsorgans color from the Farbauftragungsorgan to the side edge.

According to the inventive steps while the top and bottom of the web is kept clean, since only by the line-like contact of the side edge with the paint applicator color is brought only on the side edge. This avoids that color gets on the top or bottom of the web, whereby subsequently the material web transporting organs are kept clean in the further processing, since there is no color on the top and bottom of the web.

The contact between the side edge of the material web and the paint applicator can be achieved by removing the inking member from the ink transferring position or bringing the web back into operative contact with the non-ink transferring mold so that the side edge and the tool are in operative contact Edge region of the web is removed from the inking member, whereby the contact between the inking member and the side edge of the web is released.

Furthermore, it is possible according to the invention that markings are applied for a predetermined time at the side edge during ongoing production on a continuously conveyed material web, so that in the further processing of the cut material webs in stacked sheets in a stack tray a kind of Zählmarkierung by from the Marked material webs cut arches arise.

In the following figures, identical or similar elements or corresponding parts are provided with the same reference numerals, so that a corresponding renewed idea is dispensed with.

Fig. 1 1 schematically shows a side view of a color marking device 40 for marking side edges of material webs 20 of the paper processing industry, which is arranged on the output side of a schematically designated longitudinal cutting device 10 of the paper-processing industry. In a longitudinal cutting device, a single-layer or multi-ply wide material web is cut into a plurality of (narrow) material webs 20 so that on the output side of the longitudinal cutting device 10 the cut material webs 20 are transported via one or more deflection rollers 12 from the longitudinal cutting device 10 to a cross-cutting device (not shown here).

The color marking device 40 is by means of an angled retaining strip 14 on the outlet side of the material webs 20 below a longitudinal section 22 (see. Fig. 2 ) positioned by two webs 20, wherein the retaining strip 14 on the output side of the longitudinal cutting device 10 via brackets 16 which engage in corresponding transversely in the longitudinal cutting device 10 extending guide rails 18, on the output side of the longitudinal cutting device 10 detachably below the webs 20 according to the desired format is fixed in position. In a format change, ie at a different cutting width of the webs 20, the color marking device 40 is automatically changed by releasing the brackets 16 in the guide rails 18 in position manually or by means of a drive not shown here or moved or adjusted.

The color marking device 40 has an opening blade 44 designed as a shaping tool for the material web 20 and a marking blade 42 designed as an inking member. The marking blade 42 and the opening blade 44 are arranged in alignment with one another in relation to the conveying direction of the material webs (cf. Fig. 3 ).

In order to move the marking blade 42 and the opening blade 44 linearly and perpendicularly to the conveying plane or to the conveying direction of the material webs 20, the marking blade 42 and the opening blade 44 are connected at their underside to pneumatic cylinders 52 and 54, respectively.

In order to carry out a movement of the marking blade 42 or of the opening blade 44, the pneumatic cylinders 52 and 54 designed as actuators for the marking blade 42 and the opener blade 44 are connected to a control device 56 (shown schematically), so that the pneumatic cylinders 52 are actuated by appropriate control commands. 54 are switched to linearly move the marking blade 42 and / or the Öffnerschwert 44 accordingly.

In the upper region of the Markierschwertes 42 a color pen holder 46 is disposed in its rest position, with the use of a Colored pencil 38, for example, a felt-tip pen or the like, with its tip 34 (see. Fig. 3 ) against the side flank 62 of the marking blade 42 (cf. Fig. 4 ) is pressed to corresponding color 30 on the side edge 62 of the marking blade 42 (see. Fig. 3 ). Due to the cross-sectional view in Fig. 1 only one color pen holder 46 is arranged.

At the in Fig. 2 illustrated perspective view is located on both sides in the upper region of the marker in the rest position 42 each a corresponding color pen holder 46 so that the two side edges of the Markierschwerts 42 in contact with the color pencils 46 fixed color pencils 38 paint on the side edges 62 of the Marking sword 62 (cf. Fig. 3 ) is applied.

Above the marking blade 42 and the Öffnerschwertes 44, a guard plate 48 is arranged, which has a discharge slot on top, through which the Öffnerschwert 44 and the Markierschwert 42 pass or are moved through, so that formed as a mold Öffnerschwert 44 in the region of the side edges of the longitudinal cut Material webs 20 or is introduced into the longitudinal section, whereby the edge regions of the cut material webs 20 are raised in contact with the Öffnerschwert 44 from the conveying plane. By inserting the Öffnerschwerts 44, the edge regions of the webs 20 are pressed in the region of the longitudinal section 20 upwards, whereby a gap between the webs 20 in the region of the longitudinal section 22 is formed. Since the opener blade 44 is formed as a non-color-carrying or color-transmitting member, even when introducing the Öffnerschwerts 44 in the longitudinal section 22 no color is delivered to the continuously conveyed material webs 20.

After the edge regions of the material webs 20 are separated by a gap by introducing the Öffnerschwerts 44 in the longitudinal section 22 between two webs 20, the Markierschwert 42 is then introduced into this gap region between the side-conveyed material webs 20, wherein on the side edges 62 of the Markierschwerts 42nd Color 30 (cf. Fig. 4 ) is applied. Here, the marking blade 42 is inserted into the gap between the webs 20, without touching the webs 20 in the edge region.

For example, to mark the material webs 20 for a count on a cut stack of sheets, the Öffnerschwert 44 is pulled out after introduction of the Markierschwertes 42 in the gap opened by the Öffnerschwert 44 between the webs 20, so that after pulling out the Öffnerschwerts 44, the side edges 24 of the webs 20 against the thinner sword tongue of the Markierschwertes 42 (see. Fig. 4 ), so that the side edges 24 of the material webs 20 carry along the color 30 applied to the side flanks 62 of the marking blade 42, so that the ink 30 on the side edges 24 or the paper edge of the material webs 20 (cf. Fig. 4 ) is stripped off each.

In this case, the line-like contact between the side edges 24 of the webs 20 and the side edges 62 of the Markierschwertes 42 color 30 applied to the side edges 24 of the webs 20, wherein due to the curved contact of the webs 20 to the Markierschwert 42 no color to the underside of the webs 20 arrives. As a result, the following conveying elements in a plant of the paper processing industry, which come into contact with the underside of the webs 20, not added with color and thus not polluted, so that the conveyors are kept clean throughout the production.

In Fig. 2 is a schematic view of the color marking device 40 laterally from below below the material webs 20 shown. It can be seen that two holders 46 are arranged on both sides of the color sword 42, so that by means of the holders 46 held therein color pencils 38 are held and pressed by a tension spring or compression spring 36 against the side edges of the color sword 42. By thus biased color pencils 38, the tips 34 (see. Fig. 3 ) are pressed permanently into contact with the side edges 62 of the color sword 42 to deliver color to the side edges 62. In this case, a colored pencil 38 forms a type of ink reservoir in order to provide corresponding color for the color sword 42.

Furthermore, it is off Fig. 2 it can be seen that the color marking device 40 is arranged below the material webs 20, wherein a longitudinal section 22 extends between the two illustrated material webs 20, so that in this longitudinal section 22 for marking the side edges 24 of the material webs 20 (cf. Fig. 4 ) By pressing the pneumatic cylinder 54, the Öffnerschwert 44 is introduced, so that the edge regions of the webs 20 are curved upwards and spaced from each other, wherein in the gap thus formed then in the width or in the (thickness) diameter thinner or narrower color sword 42 is introduced.

When inserting the color sword 42 with the opener blade 44 positioned in the working position, there is no contact between the side flanks 62 of the color sword 42 and the side edges of the material webs 20. This contact between the side flanks 62 of FIG Color sword 42 and the side edges of the material webs 20 is achieved by introducing the color sword 42 in the gap opened by the Öffnerschwert 44 in that the Öffnerschwert 44 after positioning of the color sword 42 in the inking position, the Öffnerschwert 44 is pulled out by actuation of the pneumatic cylinder 54, so that the side edges 24 of the webs 20 laterally to the side edges 62 of the color sword 42 in a linear contact (see. Fig. 4 ) at the side.

Fig. 3 shows in a plan view with omission of the material webs the arrangement of the color sword 42 and the Öffnerschwertes 44, wherein the color sword 42 and the Öffnerschwert 44 are arranged in the conveying direction of the web 20 in alignment one behind the other. In addition, is off Fig. 3 to recognize that the Öffnerschwert 44 is formed transversely to the direction of the webs 20 thicker than the color sword 42nd

Further shows Fig. 3 in that the tips 34 of the colored pencils 38 on both sides of the color sword 42 are in contact with the side flanks 62 of the tongue-like color sword 42, so that ink 30 for marking the side edges 24 of the material webs 20 (cf. Fig. 4 ) is applied.

In addition, in Fig. 4 schematically shows a cross-sectional view of an introduced between two material webs 20 color sword 42, wherein the webs 20 are formed multi-layered. In the context of the invention, single-layer material webs 20 are possible.

By preforming the edge regions of the webs 20 and after pulling out the Öffnerschwertes 44 are the side edges 24 of the material webs 20 on the side edges 62 of the color sword 42 to absorb the applied to the side edges 62 in the upper part of the color sword 42 color 30, so that the side edges 24 of the webs 20 are marked laterally with color.

During the color marking of the side edges 24 of the material webs 20, the color sword 42 is actuated by actuation of the pneumatic cylinder 52 (see FIG. Fig. 1 . Fig. 2 ) is moved linearly downwards so that the movement of the color sword 42, the ink applied to the side edges 62 color 30 for marking or marking the side edges 24 is continuously provided to achieve a reliable lateral marking of the side edges 24. Here, the color 30 is brought by the movement of the color sword 42 continuously in the area between the side edges 24 of the webs 20 and the side edges 62 of the color sword 42.

In the context of the invention, it is possible, instead of the opening tool 44 designed as a shaping tool for the material web, to use another device which likewise achieves or causes an opening or a gap to be created between two material webs arranged next to one another. For example, a wedge or a roller or a blown air nozzle or another curving tool for the edge regions of the material webs 20 to be arched can also be used as the mold.

It is also conceivable within the scope of the invention that, instead of the paint applicator formed as a color sword 42 in the illustrated embodiment, other paint applicators such as a paint roller or a spray nozzle are used by a reliable order of color on the side edges 24 of Material webs 20 is achieved. Further, instead of a color pencil 38 as a color reservoir for the paint application member another, alternative ink reservoir can be provided to provide the color for the paint applicator to mark the side edges 24 of the webs 20.

Furthermore, it is possible within the scope of the invention to use the devices described by way of example in the exemplary embodiments in a plant or device of the cardboard processing industry or to apply color to the side edges of webs of cardboard processing industry.

All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention. Embodiments of the invention may be accomplished by individual features or a combination of several features.
