Description

The invention relates to a splicing device for splicing material webs, in particular paper webs for producing at least one corrugated web in a corrugated cardboard plant, according to the preamble of claim 1. Further, the invention is directed to a method for splicing corresponding webs.

Known splicing devices connect an ending, finite first material web with a new finite second material web, so that virtually an endless material web is created. This process is referred to in the jargon as splicing or splicing and corresponding devices as a splicing or splicing device. For producing corrugated cardboard webs, the endless webs of material are generally connected to one another in layers.

Tandem splicing devices are also known from the prior art. The DE 10 2011 115 936 A1 discloses such a splicing device. Such a splicing device carries more than two material web rolls whose finite material webs can be used to produce the endless material web. A disadvantage of such Splicevorrichtungen is that they have a particularly high space requirement in the machine direction. In addition, since the so-called preparation unit must be supplied with the material web from below, a walk-in and movable pedestal must be integrated between the two splicing devices which form the tandem splicing device so that the material web expires from the upstream first splicing device into the downstream second Spliceeinrichtung can be threaded. This turns out to be impractical and is costly.

From the US 2001/0018953 A1 and US 2004/0084133 A1 Splice devices are known.

The invention has for its object to overcome the disadvantages of the prior art. In particular, a splicing device with at least three dispensing devices and for connecting at least three webs of material to be created, which requires a very small footprint. A particularly simple retrofitting of Splicevorrichtung should also be possible. A corresponding method should also be supplied.

This object is achieved by the features specified in the independent claims 1 and 13 features. The essence of the invention lies in the fact that the splicing devices of the splicing device are arranged at different heights, in particular with respect to a substrate, floor or the like. The splicing device is conveniently capable of storing and unwinding at least two finite webs of material. In particular, the splicing device is also capable of processing at least three material webs. The splicing device according to the invention virtually forms a tandem splicing device. By means of the first splicing device, the finite first and second material web are splicebar to the endless material web. By means of the second splicing device, the third material web is splicebar to the endless material web. The splicing device according to the invention favorably occupies only an extremely small base area and, in particular in the conveying direction of the material web (s), has a particularly short length.

It is advantageous if by means of the splicing device, for example in the case of a malfunction of a printing device in the corrugated cardboard plant, it is possible to convert to an unprinted or job with preprinted rolls.

For example, the third material web is printed, while the finite first and second material web are unprinted. Alternatively, for example, the third web of material is unprinted while the finite first and second webs of material are printed.

The third material web is either finite or endless. To provide a finite third material web, the third delivery device is expediently designed as a unwinding device, which is spaced or adjacent to the splicing device according to the invention. To deploy an endless third material web, the third dispensing device is expediently designed as a corresponding conventional splice device, which is spaced or adjacent to the splicing device according to the invention. For example, at least one processing unit for processing the third material web or a printing unit for printing the third material web is arranged between the conventional splicing device or the unwinding device and the splicing device according to the invention.

Further advantageous embodiments of the invention are specified in the subclaims.

The tier-like design of Splicevorrichtung according to the dependent claim 2 leads to a Splicevorrichtung occupies an extremely small footprint. Known splicing devices with exactly two unwinding devices are thus particularly easily exchangeable, for example, by the splicing device according to the invention, since their base surfaces are generally substantially identical. Above all, their lengths in the conveying direction of the material web (s) are generally identical, so that there is no space problem for integrating the splicing device according to the invention into an existing corrugated cardboard plant.

The operation of the splicing device will be described in more detail below. It is first with reference to the FIGS. 1 to 3 the splicing of the finite first material web 1 to the finite second material web 4 is described. It will therefore be explained below how a change from the second material web roll 5 to the first material web roll 2 takes place when the second material web roll 5 ends, for example.

The finite second material web 4 is first unrolled from the second web roll 5 and guided into the first splice device 22 via the second feed roll 20, where the finite second material web 4 is deflected by about 90 °.

The finite second material web 4 is guided around the second pressure roller 37 in the first splicing device 22. In the second pressure roller 37, the finite second material web 4 is deflected by approximately 180 °. It is then guided out of the first splicing device 22 and to the fourth feed roller 40, where the finite second material web 4 is deflected by about 180 ° and guided into the second splicing device 38.

In the second splicing device 38, the finite second material web 4 is guided around the fourth pressure roller 62. The finite second material web 4 is deflected there by about 180 °.

The finite second material web 4 is then deflected by the first deflection roller 64 and guided around the second deflection roller 65. In the second deflection roller 65, the finite second material web 4 is deflected by approximately 180 °.

The finite second material web 4 then passes around the material web deflection roller 70 of the storage carriage 67, which is located in its second end position opposite to the outlet 69. The memory device 66 is filled with the endless material web 7. In the web deflection roller 70, the finite second material web 4 is deflected by about 180 °.

The finite second material web 4 is then guided to the outlet 69 and leaves the splicing device there.

The preparation units 19, 25, 49, 50 are functionless.

Due to the continuous rolling of the finite second material web 4, the second web roll 5 ends after a certain time, so that the finite second material web 4 must be connected, for example, with the finite first material web 1 to provide the endless web 7 and uninterrupted operation of the corrugated board plant to ensure.

For this purpose, the finite first material web 1 is first threaded through the first preparation unit 19 via the first feed device 17. The first preparation unit 19 is arranged adjacent to the first feed device 17. The first table unit 28 is arranged adjacent to the first preparation unit 19, so that the finite first material web 1 is fixed to the first preparation unit 19 or to its first adhesive roller 30. Subsequently, the finite first material web 1 is cut off by the first preparation unit 19 or its first cross-cutting unit or by hand. The finite first material web 1 is then provided at its cut web start with a one-sided or double-sided adhesive tape, which is preferably carried out by the first preparation unit 19. This condition is in FIG. 1 shown.

The first preparation unit 19 and the first table unit 28 are then displaced along the first guide 29 to the second connecting unit 27 (FIG. FIG. 2 ), whereby the first connecting unit 26 is passed.

The storage carriage 67 is thereby displaced in the direction of its first end position. By moving the storage carriage 67 in the direction of the outlet 69, the loops formed by the endless material web 7 are dissolved so that the endless material web 7 continues to be the splicing device without interruption leaves or is promoted without interruption.

The endless material web 7 is then guided by means of the second pressure roller 37 of the second connecting unit 27, this second pressure roller 37 being guided by a pneumatically operated pivoting unit (not shown) to the adhesive roller 30 of the first preparation unit 19, against the adhesive end of the single-sided adhesive tape is attached to the web start of the finite first material web 1 and is at a predetermined position on the first adhesive roll 30 of the first Vorbreitung 19 is pressed. As a result, the endless material web 7 is joined to the finite first material web 1.

Subsequently, the rolling process of the second unwinding device 6, so the finite second material web 4, stopped.

To produce a cut edge, the first table unit 28 is displaced along the first guide 29 in such a way that a cutting edge of the second cutting knife 36 of the second cross cutting device 35 of the second connecting unit 27 displaced by a linear unit (not shown) completely separates the finite second material web 4 from the second endless web 7 can dive into a provided for the second cutting blade 36 of the second cross-cutting device 35 of the second connecting unit 27 recess in the first table unit 28 over its entire width.

After the cutting process for complete separation of the endless material web 7 and the finite second material web 4 from each other, the second cutting blade 36 of the second cross-cutting device 35 of second Verbindeeinheit 27 back to its original position and subsequently the second pressure roller 37 of the second connecting unit 27 is moved back to its original position. As a result, the endless material web 7, which is now in connection with the finite first material web 1, released. The finite first material web 1 is conveyed via the first adhesive roll 30 of the first preparation unit 19 and via the second pressure roller 37.

Subsequently, the first preparation unit 19 is displaced back along the first guide 29 to a position adjacent to the first feed roller 18. The storage cart 67 is located at its first end position adjacent to the spout 69. The storage device 66 is empty ( FIG. 3 ).

Due to the known length, the roll weight and / or the roll diameter of the finite first material web 1, the splicing device recognizes when the first material web roll 2 comes to an end. Before this occurs, the prepared finite second material web 4 is connected, for example, with the finite first material web 1. This is done in the same way as the previously explained change of the finite material webs 1, 4. It is referred to.

The following is with reference to FIGS. 4 to 6 the splicing of the third material web 44 to the endless material web 7 is described. It will be explained below how a change from the first material web roll 2 to the third material web 44 takes place when, for example, the first material web roll 2 comes to an end or is switched to the third material web 44 for other reasons.

The finite first material web 1 is first unrolled from the first web roll 2 and guided into the first splice device 22 via the first feed roll 18, where the finite first material web 1 is deflected by approximately 90 °.

The finite first material web 1 is guided in the first splicing device 22 via a gap defined between the first pressure roller 34 and the second pressure roller 37 from the first splicing device 22 to the fourth feed roller 40, which deflects the finite first material web 1 by approximately 180 ° and into the second splice device 38 leads.

In the second splicing device 38, the finite first material web 1 is guided around the fourth pressure roller 62, where it is then deflected again by approximately 180 °.

Subsequently, the finite first material web 1 is deflected by the first deflection roller 64 and guided around the second deflection roller 65. In the second deflection roller 65, the finite first material web 1 is deflected by approximately 180 °.

The finite first material web 1 then passes around the material web deflecting roller 70 of the storage carriage 67, which is located in its second end position opposite to the outlet 69. The memory device 66 is filled with the endless material web 7. In the web deflection roller 70, the finite first material web 1 is deflected by about 180 °.

The endless material web 7 is then guided to the outlet 69 and leaves the splicing device there.

Due to the continuous rolling of the finite first material web 1, the first web roll 2 ends after a certain time, so that, for example, the third material web 44 can be connected to the finite first material web 1. A change between the material web rolls 2, 43 may, for example, be conditioned by a change in the order.

For this purpose, the third material web 44 is first threaded through the third preparation unit 49 via the third feed device. The third preparation unit 49 is arranged adjacent to the third unwinding device 45. The second table unit 53 is arranged adjacent to the third preparation unit 49, so that the third material web 44 is fixed to the third preparation unit 49 or to its third adhesive roller 55. Subsequently, the third material web 44 is cut off by the third preparation unit 49 or its third cross-cutting unit. The third material web 44 is then provided at its cut web start with a one-sided adhesive tape, which is preferably carried out by the third preparation unit 49. This condition is in FIG. 4 shown.

The third preparation unit 49 and the second table unit 53 are then displaced along the second guide 54 to the fourth connection unit 52 (FIG. FIG. 5 ), whereby the third connecting unit 51 is passed.

The storage carriage 67 is thereby displaced in the direction of its first end position. By moving the storage carriage 67 in the direction of the outlet 69, the loops formed by the endless material web 7 dissolved, so that the endless web 7 continues to leave the splicing without interruption or is promoted without interruption.

The endless web 7 is then fed by means of the fourth nip roll 62 of the fourth bonding unit 27, this fourth nip roll 62 being guided by a pneumatically operated pivot unit (not shown) to the adhesive roll 55 of the third preparation unit 49, against the adhesive end of the single-sided adhesive tape is attached to the web beginning of the finite third material web 44 and is located at a predetermined position on the first adhesive roller 55 of the third Vorbreitung 49, pressed. Alternatively, an overlapping adhesive bonding of the material webs 7, 44 with a double-sided adhesive tape takes place analogously. As a result, the endless material web 7 is joined to the third material web 44.

Subsequently, the rolling process of the first unwinding device 3, that is, the finite first material web 1, stopped.

To produce a cut edge, the second table unit 53 is displaced along the second guide 54 in such a way that a cutting edge of the fourth cutting knife 61 of the fourth cross cutting device 60 of the fourth connecting unit 52 displaced by a linear unit (not shown) is used to completely separate the finite first material web 1 from the first endless material web 7 in a provided for the fourth cutting blade 61 of the fourth cross cutting device 60 of the fourth Verbindeeinheit 52 recess in the second table unit 53 can dive over its entire width.

After the cutting process for complete separation of the endless material web 7 and the finite first material web 1 from each other, the fourth cutting blade 61 of the fourth cross-cutting device 60 of the fourth Verbindeeinheit 52 is moved back to its original position and then the fourth pressure roller 62 of the fourth Verbindeeinheit 52 back to its original position , As a result, the endless material web 7, which is now in connection with the third material web 44, released. The third material web 44 is conveyed via the third adhesive roller 55 of the third preparation unit 49 to the fourth pressure roller 62.

Subsequently, the third preparation unit 49 is displaced back along the second guide 54 to a position adjacent to the third unrolling device 45 ( FIG. 6 ).

The third material web 44 is guided in the second splicing device 38 out of the second splicing device 38 via a gap defined between the third pressure roller 59 and the fourth pressure roller 61. The third material web 44 is then deflected by the first deflection roller 64 and guided around the second deflection roller 65. In the second deflection roller 65, the third material web 44 is deflected by approximately 180 °.

The third material web 44 then passes around the material web deflection roll 70 of the storage carriage 67, which is located in its first end position adjacent to the outlet 69. The memory device 66 is so empty. In the material web deflection roller 70, the third material web 44 is deflected by approximately 180 °.

It will be explained below how a change from the third material web 44 to the second material web roll 5 takes place when, for example, the third material web 44 comes to an end or is switched over to the second material web 4 for other reasons.

The third material web 44 is discharged from the third delivery device 44 and guided into the second splicing device 38 via the third feed roller 39, where the third material web 44 is deflected by approximately 90 °.

The third material web 44 is guided in the second splicing device 38 out of the second splicing device 38 via a gap defined between the third pressure roller 59 and the fourth pressure roller 62. The third material web 44 is deflected by the first deflection roller 64 and guided around the second deflection roller 65. In the second deflection roller 65, the third material web 44 is deflected by approximately 180 °.

The third material web 44 then passes around the material web deflection roller 70 of the storage carriage 67, which is located in its second end position opposite to the outlet 69. The memory device 66 is filled with the endless material web 7. In the material web deflection roller 70, the third material web 44 is deflected by approximately 180 °.

The endless material web 7 is then guided to the outlet 69 and leaves the splicing device there.

Due to the continuous dispensing of the third material web 44, this comes to an end after a certain time, so that, for example, the finite second material web 4 are connected to the third material web 44 can. A change between the web rolls 43, 5 may for example also be caused by a change in the order.

The finite second material web 4 is initially guided via the second feed device 21 to the second pressure roller 37, which deflects the finite second material web 4 by about 180 °. The finite second material web 4 is threaded through the fourth preparation unit 50 via the fourth deflection roller 40. The fourth preparation unit 50 is arranged adjacent to the fourth deflection device. The second table unit 53 is arranged adjacent to the fourth preparation unit 50 so that the finite second material web 4 is fixed to the fourth preparation unit 50 or to its fourth adhesive roller 56. Subsequently, the finite second material web 4 is cut off by the fourth preparation unit 50 or its fourth cross-cutting unit. The finite second material web 4 is then provided at its cut web start with a one-sided or double-sided adhesive tape, which is preferably carried out by the fourth preparation unit 50. This condition is in FIG. 7 shown.

The fourth preparation unit 50 and the second table unit 53 are then displaced along the second guide 54 to the third connecting unit 51 ( FIG. 8 ), whereby the fourth connecting unit 52 is passed.
