DE3343523A1 - Station for a device processing concertina-folded continuous webs, in particular printer - Google Patents

Abstract

A printer or the like processes concertina-folded continuous webs (20). The continuous web (20) leaves the printer (31) via a delivery station, for example edge (33) and is deposited with concertina-folding on a deposit pile (21), preferably only under the downward influence of the force of gravity. In order to avoid faulty folding due to deformations of the continuous web (20), there is a smoothing part (40) between the delivery station and the deposit pile (21), said smoothing part having at least two profiles, in particular tubes (41, 42), arranged spaced-apart in parallel. The continuous web (20) is guided between the profiles and along an S-shaped path in such a way that one surface of the continuous web (20) rests against one profile and the other surface against the other profile. <IMAGE>

Description

Station for a fan-fold

Straight line processing continuous webs, in particular printer The invention refers to a station for a lepo-like folded endless webs processing Nice, especially a printer where the continuous web is the printer Leaves via a dispensing station and, folding like a fan-fold, preferably only is placed under the influence of gravity down on a storage stack.

It is known that in modern data processing, word processing and other office and communication equipment endless tracks, in particular endless forms or use unprinted continuous paper. Usually these are endless Like a fan-fold, i.e. folded in a zigzag shape, and the device makes them Stacks of supplies lifted off, processed and finally at an output station, for example one output edge. The endless web then falls, mostly only under Influence of gravity, downward, folds itself along the original Folded back together and is then automatically placed on a discard pile.

The processing device can be, for example, a printer or also another processing device, for example a packaging or labeling machine. In the case of a labeling machine, the labels are namely peeled off from a carrier web and this remaining carrier web then lays itself back in said one Discard them on a discard pile.

The processing continuous webs as continuous paper, continuous form sets or continuous label sets bring j however u.

U. problems with yourself. Namely, the endless tracks are usually not stored in the place where the processing device is located. Most will be the endless tracks in a normal, non-air-conditioned storage room kept while the processing device, in particular a data processing device, is in an air-conditioned room, but mostly the climate data, in particular 'The temperature and humidity in the two rooms are different.

If you now bring the continuous web into the skin for processing, in the the device is at a standstill, the temperature and humidity of the continuous web are the same as those Values of the equipment room. In particular if the endless web is multilayered and the consist of several layers of different materials, such as this for example is the case with endless label webs, the layers warp against each other and assume a more rigid structure at the same time. Then there is that, for example Endless label burners are designed so that they are seen in the longitudinal direction several Have rows of labels, the ndlosbahn, preferably in the area the gaps between the rows of labels after they have left the output station discard the device so that an orderly, self-folding shelf on the Discard pile is no longer possible. This also applies in particular if the Continuous web is heated in a straight line or statically charged.

Since in such cases the bulging and warping in the fold area No longer folds the continuous web neatly, you previously had to hire an assistant to monitor the folding filing and, if necessary, to correct it by liand. However, this creates valuable labor tied so that one Some of the advantages that come with using endless webs are lost again walk.

In contrast, the invention is based on the object of a station of the type mentioned at the beginning, which with simple means a clean, guaranteed self-folding storage of such fan-fold like folded endless webs. In addition, the station should be simple in structure and universal in use, so that it can also be retrofitted to any device.

According to the invention, this object is achieved in that the station from a smoothing part arranged between the output station and the deposit stack there is at least two parallel and spaced profiles between through which the endless web is guided along an S-shaped path, that one surface of the endless web on the one profile and the other surface is applied to the other profile.

The station according to the invention thus solves the underlying task perfect, because due to the running of the endless track with partial looping of the Profiles, bulges or even kinks that may have occurred are slid, so that after leaving the station according to the invention, the endless web is easy folds itself on the storage stack. A helper supervision can therefore be dispensed with and the organizational advantages of the endless tracks can be used be fully exploited.

In a further embodiment of the invention, the profiles are round profiles, especially pipes.

This measure has the advantage that standard components are used can be and a particularly simple and cost-saving structure of the erfindungsmaßen Station results.

Furthermore, an embodiment is preferred in which the profiles have a fixed distance from one another, which is preferably about 0.4 times corresponds to the length grid dimension of the endless webs.

This measure has the advantage that the rigid arrangement of the Both profiles, in particular tubes, to one another continue to maintain the simplicity of the structure the station according to the invention is promoted. Due to the preferably mentioned dimensioning the distance results in a particularly good effect with the commonly used Leporello endless webs with 8 "or 15" lenght raster.

In a further preferred embodiment of the invention the angle of inclination between the plane spanned by the profiles and the central plane The connection level between the output station and the stacker can be set, preferably in a range from about 0 to 30 °.

This measure has the advantage that the wrap angle between Endless web and profiles and thus also the smoothing effect of the invention Station stepless can be adjusted, in particular as a function of the endless web used, its temperature and humidity. These The embodiment of the invention is therefore particularly suitable for such applications in which a large number of different endless webs are processed and the different conditions at the storage location of the endless webs and in the area of the Device constantly change to each other, which is the case, for example, where the The equipment room is continuously air-conditioned while the climatic values of the Change the storage room depending on the time of year or day.

One? particularly good effect is also achieved in that the Profiles are held laterally by side panels, and that in the side panels in a direction perpendicular to the connecting line of the holding point of the profiles a plurality is arranged by fasteners.

These features are used for the stepless adjustment of the o.g.

Angle of inclination and enable this stepless adjustment in particular easy way.

This is especially true when in a further embodiment of the invention the smoothing part in the fastening means around-one to the axes of the profiles parallel axis is pivotably suspended.

There is then namely the advantage that the smoothing part is due to the pivoting attachment itself, hanging down, aligns at an angle of inclination that depends on the distance the fastening means perpendicular to the line connecting the holding points of the profiles is arranged. The angle of inclination then turns out to be a connecting line between the fastening means and the center of gravity of the smoothing part.

In addition, the pivoting suspension in the fastening means the advantage that the smoothing part during the passage of the endless web in a Pivoting movement can follow the stepped course of the endless web and thus the to Exercise of the smoothing function required frictional resistance within the smoothing part harmoniously varied. This has the advantage that the endless web does not get stuck can be safely avoided in the smoothing part.

This advantage mentioned above can be further developed according to the invention can be improved in that the smoothing part in the fastening means on ropes is hung.

This suspension of the smoothing part has the additional Advantage that not only a pivoting movement about the fastening means is possible but that, in addition, the smoothing part is also used in the rope suspension according to Art a pendulum can be pivoted, so that the frictional resistance is even more harmonious changes. In addition, this measure has the significant advantage that it is a special easy attachment to any device allowed, so that the station according to the invention can also be retrofitted for almost any existing device.

As already mentioned at the beginning, those on which the invention is based occur Problems in particular with multi-ply endless webs with different materials on, so that a particularly good effect is achieved when the endless webs consists of a carrier web with glued-on labels, especially if the Labels are arranged in several rows and columns with spaces in between.

The advantage then arises that especially in the In the area of the interstices, there are effective faults in the endless web the station according to the invention will be fully smoothed and thus compensated.

Finally, another embodiment is preferred in which the Profiles provided with an electrically conductive surface and electrically interconnected are connected.

This measure has the advantage that additional electrostatic charges the endless web can be compensated by creating an electrical short circuit between the two opposing surfaces of the endless web or those present there Surface charges is produced.

This makes the station according to the invention particularly suitable for devices in which the endless web is electrostatically charged.

Further advantages emerge from the description and the attached Drawing.

It is understood that the above and those below Characteristics still explained not only in the respectively specified combination but can also be viewed individually as inventive.

The invention is illustrated in the drawing and is described in the following Description explained in more detail. Rs show Fig. 1 a cross section through an inventive endless web used (not to scale),? in .. 2 a representation. like i? i £. 1, but with the presence of a special climatic fourth, FIG. 3 is a perspective Representation of a fan-fold endless web 1 used according to the invention 4 shows a schematic side view of an apparatus for processing in a fan-fold manner folded endless webs, FIG. 5 shows a detailed illustration of FIG. 4 with one embodiment a station according to the invention, Fig. 6 is a perspective view (from the front and in an enlarged scale) of an embodiment of a station according to the invention, as it is already shown in Fig. 5, Fig. 7 is a side view of a side part of the station according to FIG. O, FIG. 8 shows a further detail of an embodiment a station according to the invention.

1 and 2 show, not to scale, in cross section an endless label web, in which a plurality of labels 11a, 11b, 11c are arranged on an orazerbane 1v. The .tiketten 11a, 11b, 11c in turn consist of a patier layer 12 and a Adhesive layer 13. During labeling, the labels 11a to 11c are removed from the carrier web 10 detached by deflecting at a dispensing edge and onto one to be labeled Item applied, as is known per se.

If the endless label web is now used in accordance with i'et. 1 from a storage room, in which a certain temperature or a certain humidity prevails, brought into the room in which the endless label web processed or processed with a tanning should be and there is a different temperature or a different temperature in the equipment room Humidity, once there is a change in the stiffness of the endless label web one, usually the track becomes stiffer. In addition, the different materials can be used the carrier web 10, the paper layer 12 and the adhesive layer 13 when changing Expand or contract temperature or humidity differently, so that the web arches, as can be seen in FIG. trane special hell play gaps 14 between the labels 11a, 11b and 11c, because im Area of these spaces 14 the train is particularly easy can discard.

3 shows a perspective view of a folded fan-fold Endless web 20 with the labels 11 on the carrier web 10. After processing through a printer, the endless web 20 lays itself under the influence of gravity on a pile 21 in which the individual sections 20a, 20b, 20c, 20d and unfold immediately one after the other onto the discard pile 21.

The same applies to processing machines, for example labeling machines, in which the labels have previously been peeled off and the remaining carrier web 10 automatically deposits on the discard pile 21, in order then to be neatly removed to be able to.

As already mentioned, the areas of the spaces 14 are special critical because the endless web 20 can deform particularly easily there. the Deformation consists essentially of a bulge 23, as in the area of a Center line 22 in Fig. 3 is entered schematically. This curvature 23 results together with a curvature directed perpendicular to it, a special deformation of the endless web 20 in an area indicated at 24 of a fold 25 in which the axes Cut lengthways spacing lumen 14. These deformations of the endless web 2G can lead to a bulge of the fold 25.

Fig. 4 shows in side view a printer 31 as an example a device that processes endless webs folded like a fan-fold. The printer 31 stands on one Table 30 and pulls from a supply stack 32 the Endless web 20 in the direction of the arrow shown.

It goes without saying that the illustration of FIG. 4 is only extremely schematic is to be understood.

The endless web 20 is. now printed in the printer 31, in which, for example a certain company imprint is applied to labels and finally leaves the endless web 20 the printer 31 via an output station, for example an edge 33. The endless web 20 now falls down and normally folds neatly on the discard pile 21 itself together. Because of the too l1ig. 3 explained bulges, which are indicated in Fig. 4 with 34, however, the case may arise that the Endlosbairn 20 does not alternately fold in one direction and in the other, but instead for example, folds in the same direction twice in succession, like this with a corner 35 inside.

4 is indicated. This disturbance in folding due to the bulges 34 leads to the fact that the endless web 20 is not neatly on the discard pile 21 but falls into the room in a disordered manner.

Fig. 5 now shows a station according to the invention with which such Disturbances can be avoided.

The station consists essentially of a smoothing part 40, the two parallel, spaced apart profiles, in particular tubes 41, 42 has. The ignition track 20 is along an S-shaped path between the Pipes 41, 42 passed through in such a way that they are attached to one pipe with their one surface and rests against the other tube with its other surface. Ever Depending on the diameter and spacing of the tubes 41, 42 there is thus a certain wrap angle between the endless web 20 and the tubes 41, 42.

In the exemplary embodiment according to FIG. 5, the distance between the tubes 41, 42 set rigidly to each other in that the tubes 41, 42 fixedly with side parts 43 are connected. According to the invention, however, it is also possible to adjust the distance between the tubes 41, 42 to be set resiliently to one another with a somewhat greater outlay in terms of equipment.

It can also be seen from Fig. 5 that the endless web 20 in the manner is passed through the smoothing part 40 so that a label side 48 is initially outside of the pipe 41 is guided and only when passing the second pipe 42 on the latter Surface. This ensures that, in the event of labels passing through of the first tube 41 should have partially loosened this when passing the second Tube 42 must be pressed on again immediately.

Finally, it can be seen from FIG. 5 that it is perpendicular in one direction to the connection line of the breakpoints of the tubes 41, 42 on the side part 43 several holes 42, 45, 46 are provided. In the one most distant from this connecting line Bore 44 is a rope 47 posted, the opposite end of which with a Appropriate suspension is connected, for example the edge>; of the device 31.

The suspension of the smoothing part 40 thus results in a twofold Pivotability, once around the axis of the bore 40 and on the other, according to kind of pendulum, around the suspension point of the rope 4? at the edge 30.

The line connecting the breakpoints of the tubes 44, Z m side part 43 thus closes with the vertical one at.

Embodiment according to FIG. 5 with the middle web between Edge 33 and stack 21 coincide, an angle 49 a. This angle 49 can preferably vary in the range from 0 to 300 or even more, it is shown greatly exaggerated in FIG. 5 for the sake of clarity.

The above-described suspension of the smoothing part 40 allows so that the smoothing part 40 follows the continuous web 20 harmonize. Since the endless web 20 is folded in steps, this results in a variant that is shown Frictional resistance when passing through the glazing part 40, so that the on it The forces exerted change continuously. The described suspension of the smoothing part In contrast, 40 allows a Hannonian movement, so that the endless web 20 is smooth can pass through the smoothing member 40.

It is understood that the smoothing part 40 also by bolts in the Bores 44 to 46 schwenkjw selsgent a can or in some other way, which is obvious to the average person skilled in the art.

In the iip. 6 and 7 is the smoothing part 40 only for the details shown. It can be seen that the @@ 41.42 parallel to each other with a fixed distance in two Side parts 43a, 43b are arranged. The side panels 43a, 43b have the shape of an angle, one of the legs 60 of which are the points of contact for the tubes 41, 42 in the form of bores 62, 63, while the other leg 61 which serves as fastening means bores 44 to 46 receives. the Side parts 43 consist of a conventional flat material, the material used is fiir the side parts 43 and the tubes 41, 42 are preferably metal, in particular steel used. The path of the endless track is indicated with 50.

In Fig. 7 is the diameter of the bores 62, 63 and thus the diameter of the tubes 41, 42 denoted by D, the bores 62, 63 have one another Distance d, the bores 44 to 46 are spaced a or

b and the bore 46 lies in an axis with the bores 52, 63. The connecting line of the bores 44 to 46 has finally from the center of the Bore 62 a distance c. In one embodiment, common i3 " up to 15 "~ endless label webs the following values are used: a = 20 mm b = 20 mm c = 24 mm d = 83 mm D = 28 mm Finally, FIG. 8 shows which electrical ; Effects the smoothing part 40 according to the exemplary embodiment of FIGS. 6 and 7 has. Are the surfaces of the tubes 41, 42 from one electric conductive material, the side parts 43a, 43b cause an electrical connection which is indicated by 70 in FIG. 8. This electrical connection 70 has in turn a balance of surface charges result, which in Fig. 8 with 71 (positive Surface charge) and 72 (negative surface charge) are indicated. The endless track can - electrically gifted - due to the structure shown in Fig. 1 and 2 the Assume the properties of a surface capacitor, in which the dielectric through the Klebeschi.cht 13 is then formed on the opposite one another Surface the surface charges 7 and 72 which cause free fall and collapse on the filing stick.

due to electrostatic forces. Runs through now the endless web 20 the tubes 45, 42 indicated in FIG. 8 with an arrow Direction, the surface charges 71, 72 are connected by the indicated connection 70 shorted.
