Abstract

The invention relates to a device (1) for winding up web-shaped materials (17) into finished ready rolls (R, R'). Using said device (1) it is possible to produce rolls at high speed and with good quality. The device (1) has a winding shaft (16, 42, 46), which rests on at least one support roller (14, 15). However, the winding shaft (16, 42, 46) is preferably mounted on two support rollers (14, 15), which are disposed adjacent to one another. To this end, the winding shaft (16, 42, 46) is disposed uninterrupted from the beginning of the process between the support rollers (14, 15) and a contact roll (24). Said contact roll (24) presses the web-shaped material (17) solidly against the winding shaft (16, 42, 46) during the winding procedure. The winding device (1) additionally has a crosscutting device (32) for cutting across the web-shaped material (17). To this end, the crosscutting device (32) and the contact roll (24) can be vertically guided independently of one another.

Description

Apparatus and method for winding web-shaped materials

description

The invention relates to a device according to the preamble of claims 1, 15 and 16 and a method for producing rolls according to the preamble of claim 17.

Winding devices are used for winding web-like materials on freely rotatable winding shafts to ready-made roles.

Known is a device for roll change and cross cutting of high-speed webs in multi-winding machines (DE 1 774 101). In this case, before being cross-cut, the web is guided around more than half the circumference around an empty sleeve located in the position for changing the reel and the web is cut on the empty sleeve by a knife moved across the web. The knife is so limited rotatably mounted on a serving for its transverse guide carriage around a lying in the knife plane and standing in the radial direction of the sleeve axis that automatically adjusts itself in the resulting from goods speed and cross cutting speed cutting direction.

Also known is a rewinding machine with a first and a second lower winding roller, which comprises a winding frame for a roll of a fabric (EP 1 375 401 B1). The rewinding machine also includes an upper roller having a mobile axis disposed above the first and second lower winding rollers and supported by two movable carriages to facilitate an increasing roller in the winding cradle.

The object of the present invention is to provide a winding device which operates at a high winding speed and a winding method with this winding device.

This object is achieved by the features of claims 1, 15, 16 and 17. The invention thus relates to a device for winding web-shaped materials into ready-made rolls which have a diameter of more than 1 inch (= 25.4 mm). With this device, it is possible to produce rolls with a high speed, which also have a good quality. The quality of the rollers is therefore very high, because the layers of the web-shaped material are fixed to each other.

This can be achieved in particular by providing a winding shaft which rests on at least one support roller. Preferably, however, the winding shaft is mounted on two juxtaposed support rollers. In this case, the winding shaft is arranged continuously from the beginning of the process between the support rollers and a support roller. This support roller presses the web-like material firmly on the winding shaft during the winding process. The winding device also has a cross-cutting device for transverse cutting of the sheet-like material. The cross-cutting device and the support roller can be guided vertically independently.

When the winding process is finished, the roll is separated from the web-like material by means of the cross-cutting device, without the winding process having to be interrupted, which is achieved by providing a new, empty winding shaft, even before the full winding shaft has been separated from the web-shaped material. If the roll has been separated from the web-shaped material, then the full winding shaft is removed from the winding device.

An embodiment of the invention is illustrated in the drawings and will be described in more detail below. Show it:

Fig. 1 is a perspective view of an apparatus for winding web-shaped

Materials;

FIG. 2 shows a section along A-A through the device shown in FIG. 1; FIG.

FIGS. 3A to 3F show the removal of a roll of carrier rolls of the device according to FIG

Fig. 1;

FIG. 4 shows a detail of the device shown in FIG. 3D; FIG. Fig. 5 shows a detail of the device according to FIG. 1, wherein a web-shaped material is severed by means of a cross-cutting device.

Fig. 1 shows a device 1 for winding web material, wherein in Fig. 1, the material for clarity is not shown. The device 1 comprises a frame 2, which consists of several sections, wherein in Fig. 1, the sections 3, 4, 5, 83, 85, 84 and a transverse bar 10 can be seen. The device 1 also has a control cabinet 7, in which the control of the device 1 is located.

The device 1 further comprises a pivotable support frame 6, which is connected via means 8, 81 with a drive 9. As shown in FIG. 1, these means 8, 81 can be two racks 8, 81, which are connected to a gear drive 9. This gear drive 9 is arranged on the crossbar 10, which connects the two sections 3, 83 of the frame 2 with each other. The gear drive 9 has a motor 68 in the central portion of the crossbar 10. On this motor 68 shafts 69, 70 are arranged on both sides, which connect the motor 68 with the two bushings 71, 72 for the racks 8, 81. These bushings 71, 72 each have a gear, with which the shafts 69, 70 can be moved. However, the gears are not visible in Fig. 1. By movement of the two shafts 69, 70, the racks 8, 81 are moved either in the direction of the arrow 11 or the arrow 12.

It is understood that instead of such a gear drive 9 and a device can be used, which instead of the racks 8, 81 chains or belts that connect this device to the support frame 6.

Since the racks 8, 81 are connected to the support frame 6, by the movement of the racks 8, 81 in the direction of arrows 11, 12 and the support frame 6 in the direction of arrows 11, 12 are moved. Since the support frame 6 is connected via a shaft 67 to the frame 2, the support frame 6 performs by the movement in the direction of the arrows 11 and 12 only a tilting movement.

At the two opposite sections 3, 83 holding devices are also arranged. In this case, only the holding devices 35, 76 and 79 can be seen in Fig. 1. With These holders 35, 76 and 79, the ends of winding shafts can be maintained. The holding device 35 is arranged offset from the holding device 76. This makes it possible that both holding devices 35, 76 can simultaneously hold one end of a winding shaft.

In Fig. 1 also more support rollers 14, 15, 43, 44 can be seen. The support rollers 14, 15 and 43, 44 are each arranged as a pair. These support rollers 14, 15 and 43, 44 serve as a support for a winding shaft. In Fig. 1, such a winding shaft

16 shown. This winding shaft 16 rests on the support rollers 14, 15. On this winding shaft 16, a web-shaped material is wound into a roll.

Furthermore, the device 1 has a guide element 27, which has two opposite frames, which are connected to one another via a transverse bar 29. In Fig. 1, only the frame 80 can be seen.

Fig. 2 shows a section A-A through the part of the device 1 shown in Fig. 1 for winding web-like materials 17, d. H. 1 shows a side of the frame 2 with both sections 3, 4 and the top 5. The support frame 6 is connected via the racks with the gear drive 9, which on the crossbar 10th is arranged. In Fig. 2, however, only the rack 8 can be seen. The gear drive 9 serves to move the racks in the direction of arrow 11 and 12, respectively. If the rack 8 is moved in the direction of the arrow 11, the support frame 6 arranged on the rack 8 is also tilted in the direction of the arrow 11. The support frame 6 has on its underside 13 two juxtaposed support rollers 14, 15, which have an intermediate region 58, on which a winding shaft 16 is arranged, on which the web-shaped material 17 is wound into a roll R. The role R is shown only schematically. It is understood that it is also possible to arrange the winding shaft 16 on only one support roller 14 or 15.

The web-shaped material 17 extends in the direction of the arrow 18 over a plurality of rollers 19 to 23 in the direction of the two support rollers 14, 15. On the support roller 15, the material 17 is guided around, so that it comes into contact with the winding shaft 16. The material

17 is wound in the direction of arrow 41, that is, in the clockwise direction. On the arranged on the winding shaft 16 roller R is a support roller 24 which is arranged via an arm 25 to a holding device 26. This holding device 26 is movably arranged in the guide element 27. This guide element 27 consists of two opposite frames, in Fig. 2, only the frame 28 can be seen. These frames are connected to each other via a crossbar 29. The frames serve as guide rails, along which the holding device 26 can be moved together with the support roller 24 in the direction of arrows 30 and 31, respectively.

Evident is also a cross-cutting device 32 with a cutting element 54, z. As a blade 54 made of steel or other cutting material. This transverse cutting device 32 is likewise arranged in the guide element 27 and can thus also be moved in the direction of the arrows 30, 31. By means of the cross-cutting device 32, the web-shaped material 17 can be separated from the winding shaft 16 by transverse cutting. For this purpose, the transverse cutting device 32 must be moved in the direction of the arrow 31.

It can also be seen a part of a holding device 33 for the winding shaft 16. This holding device 33 is arranged in guide rails, wherein in Fig. 2, only the guide rail 34 can be seen. These guide rails are arranged in a pivot arm 55 of the support frame 6, whereby the holding device 33 along the guide rails, d. H. in the direction of the arrow 30 and the arrow 31 can be moved.

Further recognizable is the holding device 35, which has a holding element 36 which serves to encompass one end of a winding shaft. This is not shown in Fig. 2. The holding device 35 opposite holding device can not be seen in Fig. 2.

The holding device 35 is movably arranged in the section 3, since the section 3 forms a guide element. As a result, the holding device 35 can be moved in the direction of the arrows 31 and 30, respectively.

The holding device 76, as can be seen in FIG. 1, is not shown in FIG. 2 for the sake of clarity. Below the holding device 35 can be seen on rails arranged carriage 38, which can be moved in the direction of the arrows 39 and 40, respectively. In Fig. 2, however, only the rail 37 can be seen. The carriage 38 has on its upper side two juxtaposed support rollers 43, 44, on which a winding shaft, on the already web-shaped material 17 was wound, can be moved. In this web-shaped material 17 may be z. B. to paper, nonwoven, films and / or cardboard act. These support rollers 43, 44 also have an intermediate region 62 on which the roller can be arranged

In Fig. 2 also arranged on rails transport device 45 can be seen for an empty winding shaft 46, which can be moved in the direction of the arrow 39 and 40, respectively. In Fig. 2, however, only the rail 47 can be seen. By means of the transport device 45, the empty winding shaft 46 is moved to a transport unit 48. 2, the transport device 45 is arranged next to this transport unit 48. This transport unit 48 has two shafts 49, 50 around which a belt 51 or a chain 51 is arranged. If a chain 51 is arranged around the shafts 49, 50, these shafts 49, 50 may be gear wheels 49, 50. On the chain 51 and the belt 51, a receiving device 64 is arranged, on which an empty winding shaft 42 rests. Furthermore, the device 1 has a ridge 53, which is arranged above the transport unit 48.

Also seen is another cart 66, which is arranged on rails 75. This carriage 66 serves to accommodate finished roles, which can then be removed by means of the carriage 66.

FIGS. 3A to 3F show the removal of the roll R arranged around the winding shaft 16 from the support rolls 14, 15. For the sake of clarity, the roll R is shown only schematically.

As can be seen in FIG. 3A, the roller R is arranged on the carrier rollers 14, 15. In this case, the winding shaft 16 is held by the holding device 33. The holding device 33 has two opposite holding elements, which surround the ends of the winding shaft 16 at least partially. In Fig. 3A, only the holding member 57 can be seen. The- SES holding element 57 - as well as the opposite him holding element of the holding device 33 - is formed pliers-shaped. However, the holding elements of the holding device 33 may also be hook-shaped. However, such a hook-shaped holding element is not shown in Fig. 3A.

The holding device 33 is arranged in guide rails, wherein in FIG. 3A only the guide rail 34 can be seen. This guide rail 34 is arranged in the pivot arm 55. This pivot arm 55 is pivotally mounted in the support frame 6.

Furthermore, the holding device 76 can be seen, which also has a holding element 77. This holding device 76 is arranged hanging on a rail 78 and can be moved in the direction of arrow 39 or 40. In this case, the holding device 76 has an arrangement of a plurality of joints, which allow the holding member 77 can be moved in the direction of the arrows 30 and 31, respectively.

In Fig. 3B it can be seen that the support frame 6 is tilted in the direction of the arrow 11. This happens because the racks - wherein only the rack 8 can be seen in FIGS. 3A and 3B - are moved in the direction of the arrow 11. In this case, the rack 8 is moved in the direction of the arrow 11 by the gear drive 9, which has a motor. The motor can not be seen in FIGS. 3A to 3F.

If the roller R has reached the desired size, the carriage 38 in the direction of arrow 39, d. H. moved in the direction of section 3. It is advantageous if the size of the roller R is measured by means of lasers, not shown here. The roll R is then moved onto the two support rollers 43, 44 of the carriage 38. For this purpose, the swivel arm 55 is moved with the holding device 33 in the direction of the arrow 60. The holding device 33 thereby releases from the winding shaft 16 with the roller R.

As can be seen in Fig. 3B, and arranged on the support frame 6 support rollers 14, 15 in a tilted position and thus no longer in a plane to the two support rollers 43, 44 of the carriage 38. As a result, the center of gravity shifts to the Holding device 33 arranged winding shaft 16 with the roller R. By the publisher tion of the center of gravity of the roller R is exerted on the pivot arm 55 with the holding device 33 arranged thereon a force that moves the pivot arm 55 in the direction of the arrow 60. The pivot arm 55 with the holding device 33 is thereby arranged perpendicular to the support roller 43. As a result, the roller R also moves in the direction of the arrow 60, ie in the direction of the carriage 38.

Evident is also the holding device 76 which engages around the winding shaft 16 at its ends together with the holding device 33. As soon as the winding shaft 16 is covered by the holding device 76, the holding device 33 is moved in the direction of the arrow 30. The holding of the winding shaft 16 with the roller R arranged thereon is thus taken over by the holding device 76.

In Fig. 3C, the support frame 6 has been moved with the pivot arm 55 back to its original position. It can be seen that the holding device 76 along the rail 78 in the direction of the arrow 39, d. H. was moved in the direction of the holding device 35. Both holding elements 35, 76 now jointly hold the winding shaft 16.

Furthermore, it can be seen in FIG. 3C that by means of the transport unit 48, the empty winding shaft 42 in the direction of the arrow 52, d. H. has been transported in the direction of the arranged below the support roller 15 holding member. However, this retaining element can not be seen in FIG. 3C. By means of this holding element can then take up the empty winding shaft 42 and position this winding shaft 42 on the lying between the support rollers 14, 15 intermediate region 58, so arrange the winding shaft 42 where in Fig. 2, the winding shaft 16 is arranged.

In Fig. 3D, the winding shaft 42 has been removed by means of the holding member of the receiving device 64 and moved into the intermediate region 58. It can also be seen that the support roller 24 rests on the winding shaft 42. This winding shaft 42 is already surrounded by material 17.

It can also be seen that the transverse cutting device 32 has been moved in the direction of the arrow 31. By means of the cutting element 54, the web-shaped material 17 is then separated from the roll R. Characterized in that the role R of the web-like material 17th has been disconnected, a new winding process can be started because the empty winding shaft 42 is already provided.

3E shows the roller R, which is held only by the holding device 35. The holding device 76 has been moved back in the direction of the arrow 40. The holding element 77 can then be moved back into the desired position by movement in the direction of the arrow 30 or the arrow 31, in order to be able to receive the winding shaft 42, after material 17 has been wound into a roll around this winding shaft 42. It can also be seen that the carriage 38 has been moved in the direction of the arrow 40. Simultaneously, the carriage 66 has been driven below the roller R, so that the roller R is now arranged on the carriage 66.

Since the new winding process has already begun, a new roll R 'has already formed around the winding shaft 42. On this role R 'the platen roller 24 is arranged. In this case - the longer the process lasts - more and more material is wound around the winding shaft 42, whereby the circumference of the roll R 'in the course of the winding process is getting bigger. In this case, the support roller 24 is always on the role R 'on. With increasing scope, the winding shaft 42 is also raised in the direction of the arrow 30. The holding shaft 33 holding the winding shaft 33 also moves in the direction of the arrow 30.

In Fig. 3F is shown that the holding device 35 is raised, d. H. was moved in the direction of arrow 30. As a result, the roller R arranged on the winding shaft 16 is exposed on the carriage 66. The roller R can thus be moved in the direction of the arrow 39 and thus removed from the device 1.

In this case, the insertion strip 53 is now arranged above the support roller 15. When severing the web-like material 17, the cutting element 54 of the cross-cutting device 32 can thus strike the insertion strip 53, but not the support roller 15. The support roller 15 is thus protected by the Einschlagleiste 53 in front of the cutting element 54.

In principle, the winding process thus has the following steps: a) A first empty winding shaft is provided; b) the winding shaft is brought into contact with the underside of the sheet-like material, whereby the winding shaft is at least partially surrounded by the material; c) it is placed a support roller on the partially surrounded with material winding shaft; d) the winding shaft surrounded by the material is moved in the direction of the arrow 41, whereby a roll of web-like material is formed by movement of the winding shaft in the clockwise direction; e) the roll is separated and removed from the web-shaped material and f) simultaneously with step e) a second empty winding shaft is provided and g) steps b) to f) are repeated.

FIG. 4 shows a section of the device 1 shown in FIG. 3D. The state of the winding process is shown, which lies between that in FIG. 3C and FIG. 3D. Only the transport unit 48, a part of the support frame 6 and the holding element 86 can be seen. By means of this transport unit 48, the winding shaft 42 can be moved in the direction of the arrows 52 and 87, respectively. Also visible is a portion of the sheet material 17 which is moved in the direction of the arrow 18. In this case, the material 17 surrounds the arranged on the support frame 6 support roller 15 at least partially.

The holding element 86 with the empty winding shaft 42 has already been moved in the direction of the arrow 65 and is arranged above the two support rollers 14, 15. After the holding element 86 has assumed the position shown in FIG. 4 with the winding shaft 42, the receiving device 64 is moved in the direction of the arrow 66.

Evident is also the insertion strip 53, which is arranged above the support roller 15 and prevents the support roller 15 is damaged during the cutting of the web-like material from the cutting element, not shown here.

An advantage of this supply of the empty winding shaft 42 is that this winding shaft 42 is supplied from below and comes directly in contact with the web-shaped material 17. The winding shaft 42 is at least partially wrapped by the material. By arranging the support roller 24 on the partially wrapped with the material 17 winding shaft 42, a pressure on the winding shaft 42 is given. In the winding process, the material is thus firmly on the winding shaft 42 and der Rolle at. This significantly increases the quality of the wound roll. In Fig. 4, the platen roller 24 is not yet arranged on the winding shaft 42.

Since the layers of material in the roll are tightly engaged, higher quality rolls with a diameter greater than one inch can be produced. Also, with this arrangement, a higher winding speed can be obtained, whereby the winding process can be accelerated. With this device 1 rolls of more than 1, 5 m diameter can be produced. Also rolls with a diameter of more than 3 m can be produced. Since the winding process is very fast, costs can be saved.

5 shows the cutting of the material 17. The device 1 can be seen with the support rollers 14, 15 arranged on the support frame 6, on which the winding shaft 42 is arranged. On this winding shaft 42, the support roller 24 is arranged. The transverse cutting device 32 can also be seen. This transverse cutting device 32 is a pneumatically operated cylinder. Thus, by exerting a pressure on the cutting element 54, the web-shaped material 17 is separated from the roll R. In this case, the material 17 is severed transversely to the direction 18. If the material 17 has been severed, then the cross-cutting device 32 moves back in the direction of the arrow 30 along the guide rail 27 back to the starting position. This starting position is shown in Fig. 2.

It is thus advantageous that in the winding process carried out with this device 1, prefabricated rolls of high quality can be produced very quickly. The web-shaped material 17 is thereby separated from the roll, without causing the winding process must be interrupted. This is achieved by providing a new winding shaft even before the web-like material 17 is separated from the roll by means of the cross-cutting device 32.

Although the embodiments of the invention have been described above in detail, the invention is not limited to these embodiments. A person skilled in the art will understand that the invention includes various variants with which the same result is achieved as with the exemplary embodiments described here. It is therefore clear to those skilled in the art that with the embodiments described herein The scope of the claims is not limited and that there are other variants, modifications and alternatives that fall within the scope of the claims.
