Abstract

The embossing rolls (1, 4) of embossing devices (14) that are used for processing two-dimensionally expanded material, especially in the packaging industry, can be exchangeably configured if they are mounted in suitable exchanger units (2). An exchanger unit can be configured, for example, as a tube (2) with terminal locating surfaces (8, 9). The stand (13) of an embossing device (14) has corresponding seats (11, 12) that are adapted to the respective exchanger unit (2) with high precision. The embossing roll (1, 4) that is received in an exchanger unit (2) is thus in its working position once it is inserted and the locating surfaces (8, 9) of the fixing elements are received by the pertaining seats (11, 12) and no further adjustment needs to be carried out. Especially the driven embossing roll (1) of such an embossing device (14) can be exchanged with substantially less effort, which makes it possible to quickly perform maintenance work and rearrange the production.

Description

The present invention relates to an embossing device for extensive material according to the generic term of the Claim 1 are preferred as such material or tapes Understand sheets that are coated on one side with aluminum are and their carrier made of paper or in general one consist of fibrous material, or foils, e.g. B. from Plastic, metal or compound materials.

Such embossing devices are u. a. in the Packaging industry for satinizing packaging material used, preferably also signets, Lettering, etc. are stamped. Under satinizing understood the surface with a fine grid in the Millimeter and submillimeter range. Such sheet-like packaging material is used for. B. for the packaging of tobacco products (cigarettes), food, Chocolate, chewing gum etc. are used. An embossing device for this purpose was in the European patent application Applicant's EP-A-0 686 782.

The requirements for such embossing devices, such as high Running speed (e.g. 1.8 m / s), a fine, absolute uniform grid and an otherwise flawless embossing during long, uninterrupted hours of operation a high degree of precision in construction and furnishing such embossing devices. In the known versions is therefore the entire so-called embossing head, i.e. a Frame with embossing rollers and u. a. one Adjustment device, on the embossing machines as external Establishment attached. Some of these embossing heads weigh more than 50 kg.

Because the rollers are predictable wear are subject to regular maintenance by Make embossing heads, especially from time to time the rollers are replaced. But also the change u. a. to a different surface structure, a different signet or another format requires a roll change. At the known embossing heads, it is necessary to the whole Take off the embossing head, take it to a workshop, there the the necessary work, close the embossing head again assemble and because of the inevitable Loss of adjustment may add one time-consuming readjustment. Such a Operation can take several hours, and when you lose weight and Attaching the embossing head to the packaging machine are in usually at least two people or additional Lifting tool necessary because of the heavy weight.

For a faster change, there is one to keep the second embossing head in stock. This solution is on the one hand, however, it is financially very complex and avoided on the other hand, not the need for the newly installed Embossing head on the material run of the packaging machine exactly adjust.

It is therefore an object of the present invention to to specify an embossing device of the type mentioned, the one facilitated access to the embossing rollers.

Such a device is specified in claim 1. The further claims indicate preferred embodiments.

The basis of the invention is the surprising finding that it is not absolutely necessary, especially the driven one To hold the embossing roller directly in the frame of the embossing device. This driven embossing roller is on the one hand with the drive coupled with the packaging machine and is also precise on the direction of the material to be embossed to set up.

According to the invention, however, in contrast to the prior art Technology, this roller with suitable holding means on a Kind in the frame of the embossing device that they can also be removed again with little effort or is interchangeable, practically without one Readjustment is necessary. These holding means are preferred attached to both ends of the embossing roller and take the Bearings for the axes of the embossing roller. In their outer They are complementary in shape with high precision corresponding recordings in the frame of the embossing device formed so that the embossing roller preferably under Take away the holding means from the recordings or can be used in these, at the same time an exact positioning takes place. Are preferred additional locking means and / or securing means present, such as set screws or clamps to on the one hand the exact seat, if necessary also in terms of targeting a particular one Rotational position, at least to ensure the holding means and on the other hand, a displacement of the embossing roller by z. B. Prevent vibrations during operation.

It has been shown that it is also possible as Holding means to provide those that the embossing roller in support removed condition, and the bearing firmly in the frame to provide.

The counter roll was relative in the prior art by easily accessible screws with the appropriate Adjustment and / or pressure device connected and could therefore already in the known embossing heads less effort can be exchanged. The benefit from it was limited, however, because e.g. B. when changing one lettering to be embossed replaced both rollers must be used, since the embossing rollers are in contact with one another during operation adjust and changing only one of the two rollers too Malfunctions and higher wear. For this The reason is an advantageous development of the invention in it, also the counter roller with analogue holding means equip and replace them in a simple way can. At the same time it is possible for different To have a pair of embossing rollers in stock, without the need for intolerably high investments are.

Even equipping the counter-rollers with holding means at the same time in a conventional way in the frame driven embossing rollers means one Progress in ease of maintenance as the change compared to a conventionally held counter roll to driven embossing rollers easier, but still with one Time is associated with the present invention is significantly reduced. The invention gains importance in this area additionally because of a trend towards there are several counter-rollers and it appears possible that Wear especially those with the embossed pattern Surface essentially towards the counter roller (s) restrict.

Parts corresponding in different figures are with the provided with the same reference numerals.

1 and 2 show a first embodiment of the Invention, in which the driven embossing roller 1 in one generally cylindrical sleeve 2 is rotatably mounted. The Sleeve 2 has one over the working length of the embossing roller 1 Cutout 3 so that the counter roller 4 on the embossing roller 1 can be created (see Fig. 2).

The driven, first embossing roller 1 is provided with roller bearings 6 precisely rotatably supported in the sleeve 2. The sleeve instructs the two ends each have a mating surface 8 and 9, respectively exactly to the openings 11 and 12 in the frame 13 of the Embossing device 14 are adapted. The sleeve 2 can thus inserted in the direction of arrow 15 in the frame 13 until the end plate 16 strikes the frame 13, and generates an exact radial positioning of the driven embossing roller 1 in the frame 13 by means of Drive 21. By screwing in the locking screws 18 in the sleeve 2, this is in a predetermined, optimal Fixed rotational position and also z. B. against shaking out secured. From the external drive 20 indicated in FIG. 1 a shaft 21 projects into the opening 11. The Drive end 22 is when inserting the sleeve 2 to the Drive end 23 of the embossing roller 1 coupled. This coupling can be done in a number of ways in engineering are known and depend on the local conditions, e.g. Carriers or gears. For the coupling process it may be necessary to insert the embossing roller 1 into a specific position Position to twist what is done by attacking the one hand Embossing roller 1 in the cutout 3 or by turning the second shaft 24 of the driven embossing roller 1 can then z. B. through the end plate 16 is accessible.

The counter roller 4 is, as indicated schematically in FIG. 1, after loosening their attachment to a usual Holding device, which preferably also moves apart the embossing rollers allowed, e.g. B. according to the above European patent application by the applicant, top (Arrow 26) removable. Execution of the bracket of the Counter roll 4 is therefore no further in the figures executed and does not need to be explained further become.

Like FIG. 2 compared to the schematic illustration in FIG. 1 clearly shows, the mating surface 8 is smaller Diameter than the embossing roller 1, so that it is sufficient to counter roller 4 by loosening the biasing device to lift off the embossing roller 1 to remove the latter from the frame 13 to be able to pull out. As in this embodiment recognizable, it is possible to use only the embossing rollers to replace without the frame with all attached Additional devices such as drive arrangements also need to remove. It is also possible to use the frame as an integral part of a packaging machine to execute. With the easy interchangeability of the mainly parts subject to wear (embossing rollers, Warehouse) is now also maintenance with less effort Share and thus more environmentally friendly possible.

Because of the simplicity of the change process, it is too conceivable, after appropriate adjustment, for. B. Replacement of Locking screws by pins or the like, changing of the embossing rollers to be carried out semi or fully automatically. In this connection can also be provided Wear of the embossing rollers via appropriate sensors it on the product or directly on the embossing rollers check. The sensors or any other Measuring arrangements could also be able to send one to the Embossing rollers to read existing code and thus a automatic detection of the embossing rollers used realize. One way of automatic Wear control is one at one end to provide a polished, smooth zone surrounding the roller. The Position of the surface of this measuring zone can be highly accurate by means of z. B. an optical sensor relative to the frame be recorded. The sensor arrangements required for this are known per se. If the embossed pattern is worn provided surface of the embossing rollers, the z. B. from Pyramids in the range from micrometers to a few millimeters can have, the embossing rollers move relative to Frame and thus generate on the sensors corresponding signal. With conventional embossing rollers, this is Distance of a roller until total wear of the Surface z. B. 150 microns. If the signal exceeds one certain threshold, d. H. the wear has a certain If the limit value is reached, the embossing rollers can be changed be requested, be it by a corresponding signal for the operators, whether by activating a semi or fully automatic change system.

By modifying the sleeve 2 such that it is next to the driven embossing roller also receives the counter roller, it is possible to use the two embossing rollers in their To exactly synchronize the rotational position relative to each other. This framework does not necessarily have to be in one piece, but can also include several parts that are loose per se, of which one carries the driven embossing roller in the manner of the cover and a second part receives the counter roller. That frame is then preferred only by inserting the parts into the corresponding recordings put together in the frame 13 and fixed relative to each other. An example of this is hereinafter as the ninth exemplary embodiment (FIGS. 12, 13) called.

Finally, it is also conceivable that the inventive Use construction for multi-roll systems. As Multi-roll systems are to be understood as devices in which several, in particular more than two, rollers on the embossing and / or transport process are involved.

The exemplary embodiments described below clarify some of the suggested variants:

In Fig. 3 the frame 13 is substantially rectangular Recordings 30 in which the corresponding, rectangular fitting surfaces 31 having sleeve 2 from above can be inserted or removed upwards.

Fig. 4 shows a variant in which both the driven Embossing roller 1 as well as the counter roller 4 in sleeves 2 and 35 are included. It is provided that the counter roller 4 is so eccentrically arranged in the sleeve 35 that it protrudes sufficiently far forward from the cutout 36, that they hit the surface of the driven embossing roller 1 can be pushed in. This movement on the driven Embossing roller 1 becomes movable in slots 38 arranged receiving pieces 39 guaranteed. The Receiving pieces 39 are with a not shown Adjustment and pressure device according to the prior art in Connection.

The necessary alignment with regard to the rotational position of the sleeves 2 and 35 takes place through the end disks 16 and 40, which are only in the permissible position the necessary for the operation Allow embossing rollers 1 and 4 to approach. For example this is done by making each one straight Section 41 have.

Fig. 5 shows an embodiment that with respect to driven embossing roller 1 essentially of FIG. 3rd corresponds. Here, however, is also the counter roll 4 in one U-shaped holder 42 mounted. The holder 42 is in the Recesses 43 used, each one on the bottom Have guide rail 44, when inserting the holder are taken up by invisible grooves, which are shown in the end parts 46 are present. The grooves are exactly on the rails 44 adjusted, creating a precise axial Positioning of the counter roller results. On the driven embossing roller 1, the holder 42 with the Counter roll 4 can be moved along the rails 44. This Movement as well as providing a defined Contact pressure on the first embossing roller 1 can be carried out again an adjusting and pressing device according to the state of the Technology. So on a presentation waived.

Fig. 6 shows an embodiment in which driven Roller 1 and counter roller 4 are in an interchangeable frame 48. The interchangeable frame 48 has T-shaped grooves 49 on the bottom, by means of which it fits from the side onto the rails 50 inserted in the frame 13 in the direction of arrow 51 can be. During the insertion process, the for example specified stamp 52 of the adjustment and Pressing device for the counter roller 4 withdrawn and are after inserting the removable frame 48 in the Working position advanced to the second embossing roller 4 to press the first embossing roller 1 in a defined manner. Since the Working position of the stamp 52 is defined, too No readjustment is necessary here, it is sufficient to Adjustment device from the rest position, the insertion enables to the preset working position bring.

7 shows an embodiment similar to that of FIG. 6, in which, however, the removable frame 48 and the rails 50 so are executed that the removable frame 48 with the Embossing rollers 1, 4 from above according to arrow 53 into the frame 13 can be used.

8 and 9 finally show a variant in which the middle of the sleeve 2 has been omitted, d. H. the Embossing roller 1 is accessible in its entirety. To the Both ends of the embossing roller 1 are fitting pieces 55 (Drive side) or 56, which the bearings 6 for Pick up embossing roller 1 and peripherally with the mating surfaces 8 or 9 are equipped. It is the same in application otherwise that of FIGS. 1 and 2, in particular regarding the insertion process. The backup takes place here, however, preferably via screws 57, which are in axial Direction to the embossing roller 1 through the brim 58 of the end plate 16 are screwed into the frame 13.

Figures 10 and 11 show an embodiment in which the drive-side bearing 60 is arranged in the frame 13 and receives the journal 62.

The end 61 only has an annular support web 65 for the embossing roller 1 to this during the change and when storing in one position (preferably approximately in the middle) hold in the end 22 of the embossing roller 1, the one Has inner cone, on the complementary to it also conical drive pin 62 pushed on and can be coupled with it. The embossing roller end 22 can u. a. formed as an axis as shown or in the Roll body to be integrated.

Figures 12 and 13 show an embodiment similar to Figure 1 and 2, however, the two embossing rollers 1 and 4 each a ring gear 70, 71. Ready for use (Fig. 13), the sprockets are engaged and the Embossing rollers 1, 4 synchronized with force.

FIGS. 14 and 15 show an embodiment similar to FIG. 1 and 2 with a rotary knob 24, by means of which the embossing roller 1 e.g. B. for coupling to the shaft end 22 via a rough Gearing, can be rotated into a position that can be engaged. The knob is over a freewheel or a Drag clutch 75 with shaft end 76 of embossing roller 1 connected so that the button 24 during operation not necessarily co-rotating.

From the foregoing, those skilled in the art Changes to the illustrated embodiments are accessible, without leaving the scope of the invention. In particular the embossing device can be arranged in any position and be aligned. Also the specified variants are especially for coupling the embossing rollers and for manual Twist with rotary knob, can be combined with each other.

In the sides or end plates of the cassette parts, the Frame 13 or the fittings 55, 56 can, for. B. Synchronization means such as gear or belt gear be present to prevent the rotation of the embossing rollers synchronize. So it is possible to do some or all Embossing rollers 1, 4 via corresponding gears synchronize, the clutch of the transmission parts also only when the rollers 1, 4 are inserted into the frame 13 can happen.
