Abstract

The known king roll reeling machines for shaftless winding of a web of material (4) divided by a lengthwise cut, in particular a web of paper of cardboard, onto sleeves (11) have take-up rollers (6) which are applied during take-up to two king rolls (2, 3) and are supported by guide heads (10) which can be inserted sideways into the sleeves of the two outer take-up rollers (6). The take-up rollers (6) can only be wound with high winding quality up to a maximum diameter. According to the invention, the space delimited by the king rolls (2, 3) and the take-up rollers (6) is sealed and an overpressure is produced in the space. To this end, sealing elements (18) which can be displaced axially to suit webs of different widths and which can be moved simultaneously in an area outside the area of movement of the guide heads (10) and their fastener (carriage (9)) are arranged in the region of the two side ends of the king rolls (2, 3). Frictional engagement between the king rolls is prevented when the sealing elements (15, 18) are in the sealing position.

Description

[Detailed description of the invention] Support roller type winder Technical field The present invention relates to a support roller type winding machine according to the generic part of claim 1 and a supporting roller type winding machine according to the generic part of claim 17. The present invention relates to a method for winding a strip material as described in the concept section.

Such supported roller winders are used to cut strips, especially paper or cardboard, separated by longitudinal cutting. Useful for winding on a winding tube without a shaft. In this case, the winding roll is and are positioned in axial alignment in a row above the support rollers. vinegar Shaft winding in which - sets of winding rolls are held during the winding process by a shaft passing through all the winding tubes In contrast to take-up machines, in the case of shaftless winding, two guide heads are used to It is inserted into the winding tube of the winding roll.

Conventional technology In the support roller winder known from DE-A 3618955, The winding roll with the desired winding accuracy can only be obtained up to a certain diameter, and the reason for this is that the winding roll The winding hardness of the roll is determined by the line load on both support lines of the winding roll against the support roller. The hardness of the 6th roll is equivalent to (supported weight per width of one roll) as much as possible over the entire set of winding rolls and across the diameter of the individual winding rolls. The predetermined value of the per-roll hardness that is desired to be uniform and have a predetermined value. In the known support roller type winder, the support weight increases from a predetermined diameter. Therefore, the maximum roll diameter is determined.

DE-Psi is the best way to reduce the weight of a support roller type winder that winds up on a shaft. It is known from No. 111496. In this case, the support roller and the winding roll An overpressure is thus created in the restricted space. To seal the sides of said hollow chamber A cover plate adapted to the shape of the support roller is used. the cover The plate is movable to contact the end face of the body roll. downward sea Rolling is carried out with a roller or rollers that are in contact with both support rollers.

The sealing member shown in DE-Psi No. 111496 performs shaftless winding. Not suitable for use with supported roller type winders. This is because the seal member and its hardness This is because the fixed device will be located within the range of motion of the guide head. Further contact A frictional connection is formed between the support rollers on both sides by means of the sealing rollers. This connection makes it impossible to adjust different torques that affect the winding quality. Ru.

Disclosure of invention The problem of the present invention is to improve a support roller percussion winder that performs shaftless winding, and to The purpose of the present invention is to make it possible to manufacture high-quality wound rolls having a diameter.

This problem was solved by the features set out in claim 1.

The supported roller winder of the invention has the advantage of shaftless winding. That is, This eliminates the need for troublesome handling of heavy and long shafts, especially when the width of the strip material is large. It has the advantage of being able to be changed quickly, and the maximum winding diameter is The weight is not limited to any known extent. Furthermore, the load is reduced and the filtration pressure is rolled up. This constitutes another adjustment parameter that controls or adjusts hardness.

Advantageous embodiments of the invention are disclosed for m-group rings 2 and below. This offers the advantage of being able to place the elements below the supporting rollers, and on the other hand Pressurized air can be blown in from below as additional sealing air. bring benefits.

As described in claim 3, lowering the element that seals downward is a lifting and lowering process. Alternatively, this can be done with a pivoting element. It is useful for removing paper residue after paper damming, for example, 2 includes an end-side sealing member disposed on the sealing member, as set forth in claim 5. Second, in order to lower it so that it is no longer located in the movement range of the guide head. Helpful.

As stated in claim 4, the element for sealing the lower part is located in the range on the F side of the support roller. By being able to rotate up to This provides space for the separating knife to move upwardly through the gears. mentioned above Separation knives, such as the Can be used only when

In an embodiment as claimed in claim 5, the sealing member on the end face is axially connected to the support roller. It is now possible to move it out of the range. In this case, from the guide head The moving away movement is carried out by a subsequent axial movement outwards or by a guide head. This is done by additionally lowering the roller as soon as it leaves the area of the support roller. Ru.

Claims 6 to 9 provide that the end-side sealing element can be pivoted out of the area of the guide head. An embodiment of the invention is shown that is dynamically retracted. The division according to claim 7 is It has the advantage that less space is required for each swivel movement. Ru. This allows the guiding head to be positioned further down while the winding diameter is small. It has the advantage that it can already be used.

In other words, overpressure must be applied already at an early winding point in order to affect the winding quality. I can do it.

A claim in which the circular guide on which the sealing member on the end face side is supported is fixed to the pivot arm. The embodiment according to claim 8 is structurally advantageous and space-saving; The rotation axis is offset eccentrically with respect to the support roller axis in a manner that When the support roller member is pivoted over one of the support rollers, You will be pushed away. As a result, there is no problem with the remaining paper after the paper is dammed. Can be removed. In this case, the sealing member is movably supported outwardly on the pivot arm. be fixed to the inner end of the supported circular guide, or the pivot arm can be bent and The apex of the bending angle is located outside the range of the support roller. In this case so that a consistent circular guide extending over the entire working width can be fixed to the swivel arm. The seal member is movably fixed to these circular guides. This results in a yen The guide need not be moved beyond the supporting rollers when adjusting to the maximum strip width. (M group ring 9).

The sealing member equipped with a labyrinth seal according to claim 10 is provided with a In the arrangement of claim 11, the shield is characterized by a frictionless seal with the roller or support roller. The sealing effect can be enhanced by supplying cut-off air.

Claim 12 provides a seal having a seal member that achieves a high sealing effect with little friction. The structure of the surface is disclosed.

Particularly advantageous embodiments of claims 13 to 16 are possible at different overpressure values. Only allows for lateral sealing with little pressure air loss. In this case air The force between the crimping force produced by the force-type piston cylinder unit and the counterforce caused by overpressure. Equilibrium automatically maintains a minimum gap between the sealing member and the end face of the outer winding roll. The gap is removed by axial movement of a six-wound roll to form a If the pressure decreases or increases, the overpressure increases or decreases, so the This counterforce will impart a corrective movement to the sealing member.

According to claim 14, the pneumatic piston-cylinder unit has an advantageous construction. type, for axially moving the sealing element to adapt to different strip widths. Also useful. In an arrangement according to claim 15, an additional electrical or hydraulic A hydraulic drive is provided.

centered on an axis perpendicular to the axis-parallel guide as claimed in claim 16; The movable fixation of the pneumatic piston cylinder unit is achieved by using a sealing member. [Claim 7] [Claim 7] The belt material described above can be freely moved within the belt. The winding method allows the winding of very large diameter winding rolls.

In this case, adjustment and control of the winding hardness becomes significantly easier. Because important influence The value, i.e. the line load at both contact lines between the winding roll and the supporting roller is also This is because it will no longer change.

Examples of the invention Double-supported roller type winding in which only the parts relevant to the present invention are described in detail The machine has two support rollers 2, 3 supported on a machine frame 1. this The supporting rollers 2.3 are arranged parallel to the axis and at a small distance from each other and are It extends over the width, ie the maximum width of the strip 4 to be wound up. Support roller diameter are different from each other, and the axis of rotation is shifted somewhat in the height direction (first (Figures 3 to 3) or are equal to each other and the rotation axes are located in the same horizontal plane (Figures 4 to 3). (Fig. 10). A longitudinal cutting device 5 serves to cut the strip 4 into individual strips.

A winding roll 6 is formed from these single strips. The winding roll 6 is in the winding process. In this case, the rollers 2, 3 are arranged in axial rows aligned with each other on both support rollers 2, 3. It's located there. The strip material 4 is fed to the winding point from below through the support roller gap. (Fig. 1.4.8) or slightly wrapped around the supporting rollers from above. (Fig. 6) On both sides of the machine, the guide is almost perpendicular to the frame 1. 7 is fixed. This guide 7 can be raised and lowered by a piston cylinder unit 8. A highly functional shuttle 9 is being guided. The pI carriage 9 has an inwardly projecting guide head 10. have. In order to guide the roll set of the TK body roll 6 in the axial direction during winding. 0 is used to guide both outer winding tubes from the outside before starting winding. 11 and remains there until the winding roll 6 is wound up. Run to empty tube 11 In order to adapt the guide head 10 to the carriage 9 and to adapt it to the strip width of the cages. It is fixed movably in the axial direction by a drive device.

For this purpose, the carriage 9 has a hollow cylindrical guide which projects horizontally inwardly.

A bin is located in this guide and is movable in the axial direction by means of a spindle. A guide head 10 is fixed to the end of the guide head 10 . This configuration is detailed in US-PS448 No. 3493.

The guide 7 extends outside the upper wedge-shaped space between the two supporting rollers 2, 3 to Between the supporting roller axes, perpendicular to the joining line passing through the center of the supporting roller gap. They extend parallel to each other at intervals. Guide 7 is the connection line between both support rollers. It ends at the top.

The guide head 10 is attached to the winding tube 11 located in the wedge-shaped space between the two supporting rollers 2, 3. You can run in. When the winding roll 6 becomes larger, the lower edge of the carriage 9 When moved sufficiently upwards along the guide 7 with the tube 11, on both sides of the machine The upper side of the support rollers 2 and 3 should be protected from contact with the sealing member described later. Space will exist.

For roll change, the machine has a roll extrusion beam 12 and a lowering platform 13. have. The lowering platform 13 only receives the wound roll 6. lower for release. If the strip is fed from below, support rollers 2.3 A cutting knife 14 which can be raised through the support roller gap under the (Figure 6).

In order to reduce the support load on the support rollers 2 and 3, the support rollers 2 and 3 and the roll Overpressure is created by pressurized air in the space limited by the roll 6. I can do it. For this purpose, the components described in detail below are used.

The wedge-shaped space below between the two supporting rollers 2, 3 is provided in all the illustrated embodiments. An air box 15 is provided with a pressurized air supply. The air bottle The box 15 extends over at least the minimum width of the strip 4 and is connected to the upper roll 6. It has an outflow opening for pressurized air on the restricting surface facing towards. Air box 15 is on the bottom It is fixed to an elevating or rotating member so that it can be lowered. support A separating knife 1 that can be raised by passing through a supporting roller gear under the holding rollers 2 and 3 4 is arranged, there is no space for the separation knife 14 to rise. In order to obtain air box 15, one support [Cola (in Figs. 4 and 8) is fixed to a pivot arm 16 that allows pivoting to the bottom of the support roller 3). Ru. If such a cutting knife is not present, the air box 15 is a lifting member. (elevating cylinder 17) (Figs. 1 and 6). air box The side surface of the upper part of 15 facing the support rollers 2, 3 is aligned with the surface of the support roller 2.3. It is curved accordingly. In this case, the seal position should be Only a few gears remain. The side surface is the side facing support rollers 2 and 3. The support roller has a plurality of grooves extending parallel to the axis of the support roller. The groove drains It extends transversely to the outflow direction of the compressed air and serves as a labyrinth seal. sticker The height of the active side surface is adapted to the required sealing force. required seals The force is smaller on the side of the support roller moving inward into the upper wedge-shaped space than on the opposite side. be able to. This is because, in relation to the direction of rotation, the supporting roller 2 or the strip 4 on it This is because the air acting against the outflow is entrained.

In the embodiments shown in FIGS. 1 to 3, the upper surface of the air box 15 is Two end-side sealing members 1 fixed movably in the axial direction on both sides of the machine It also serves as a guide for section 8. The sealing member 18 is in the range of the support rollers 2 and 3 in the axial direction. The air box 15 is mounted on support rollers 2° on both sides of the machine so that it can be moved out of the machine. It protrudes beyond 3 (Figures 2 and 3). The shape of the seal member on the end side is similar to that of the support row. It is adapted to the free space between La 2 and 3. In this case, the upper part is square It extends above the joining line between both the vertices of support rollers 2 and 3, and has a large In the case of a winding roll 6 having a diameter of The extended portion of the groove is provided with a groove on the side facing the end face of the winding roll 6. the groove As a labyrinth seal of the type described above, the loss of pressurized air is significantly reduced. support The curved side facing the holding rollers 2, 3 is likewise provided with a groove. The groove is similar and extends transversely to the possible outflow direction. In other words, the grooves are adjacent to each other. It extends in the circumferential direction of the supporting roller 2.3. The sealing member 18 is moved on the side of the guide 7. Since the sealing member I8 moves toward the end surface of the winding roll 6, can. In this case, a small gap exists at the seal location to avoid friction. There is.

In order to move the support rollers 2 and 3 in the axial direction, each seal member 18 is provided with a A moving member (for example a drivable spindle), which is not shown, is fixed.

In the embodiment according to FIG. In order to enter the empty winding tube 11 located at It can be moved outward until it can be lowered into the form space.

In the embodiment of FIG. 3, the air box 15, together with the seal member 18, The upper edge of the material 18 is located below the narrowest part between both support rollers 2 and 3. It can be lowered until the In this case, the air box 15 is , 3 only need to extend slightly beyond the ends. The seal member 18 is Moving the outermost end of the box 15 in the axial direction is then performed by pivoting or linear movement. It only makes it possible to lower the sealing member to provide the necessary space for the carriage 9. .

In the embodiments of the present invention shown in FIGS. 4 to 1O, the seal portion on the end face side The material 18 passes over the support rollers 2 and 3 in the direction of travel of the strip or in the opposite direction by turning. and is then moved out of the working area below the guide head 10. empty in this case It is not necessary for the air box 15 to extend laterally beyond the support rollers 2,3. Therefore The length of the air box 15 corresponds approximately to the length of the support roller 2.3. upwards In order to enable the pivoting, the sealing member 18 must fit between the very narrow parts of the support rollers 2 and 3. It ends there. Correspondingly, the air box extends from below to said location. S The roll member 18 is connected to pivot arms 19.20 on both machine sides. . The pivot axis 21.22 of the pivot arm 19.20 coincides with the axis of each support roller. or extending somewhat eccentrically outwardly above the joining line between the axes of both supporting rollers. ing. A slight eccentricity is caused by the sealing member 18 facing the support roller 2 or 3. Some surface detaches from each support roller surface during outward pivoting, e.g. Allows you to remove. It is necessary to further separate the sealing member 18 from the support roller. In this case, the sealing member 18 is fixed to the double lever. From Figure 4 to Figure 7 In this embodiment, the support roller 2.3 between the sealing member 18 and the air box 15 The end facing side of the winding roll 6 is provided with the labyrinth seal described above.

In the embodiments shown in FIGS. 4 and 5, it is possible to pivot around the support roller 3 on the exit side. A lever 19 has an integral sealing member 18 on each machine side. Further reviews The bar 19 is bent at its end, which end is pivoted between support rollers 2, 3. bending of both pivotable levers 19, which extend substantially horizontally in the extended position; At each end, two guides 23 are supported so as to be movable in the axial direction. ing. A sealing member 18 is fixed to the inner side'4 portion of the guide 23. As shown in FIG.

According to the embodiment of FIGS. 6 and 7, each sealing member 18 on the end face is connected to a supporting roller gap. It is divided along a perpendicular line passing through the center of the group. Each part 24.25 of the sealing member is It is fixed to the pivot arm 19.20. These pivot arms 19.20 are adjacent The support rollers 2, 3 can be pivoted onto the supporting rollers 2, 3. This turning movement is shown in Figure 6. As shown, since only a small space is required, the sealing member 18 can be installed at an early stage. It can be used in

In the embodiments shown in FIGS. 8 to 10, the sealing member 18 is also attached to the support roller on the outlet side. The lever 19, which is pivotable about the lever 3, is mounted axially, i.e. transversely to the strip 4. It is supported so that it can move in the direction. Therefore, the sealing member 18 is attached to the support roller 3. Move the guide head 10 out of the lower working area by pivoting it upwards. (shown in dashed lines in FIG. 8), the pivoting lever 19 can be Since it is bent, the free end is in a pivoted position between support rollers 2, 3. It will extend almost horizontally. The pivot shaft 25 of the pivot lever 19 is somewhat eccentric. is offset outwardly and extends above the joining line between the axes of the two supporting rollers.

The slight eccentricity is caused by the fact that the side of the sealing member 18 facing the support roller 2 or 3 is For example, paper residues can be removed when the sealing member 18 is pivoted outwards. The rollers can be moved away from each support roller surface in order to 6. At the bent ends of both pivot levers 19 there are in each case two identical guides. 23 is supported movably in the axial direction, and a seal is provided at the inner end of the guide 23. Member 18 is fixed.

The sealing member 18 is moved in the axial direction, and the sealing member 18 is attached to the end of the outer winding roll 6. In order to press the surface, the piston of the pneumatic piston-cylinder unit must rotate. It is fixed to the upper side of the bar 19. The end of the piston rod 27 is connected to the sealing member 18. It is supported for movement about an axis extending perpendicularly to the interior 23. others A shaft 28 is fixed to the upper side of the seal member 18, and the shaft 28 is connected to the piston rod. Guided through 27 eyes. Pneumatic piston cylinder unit 26 ゜27 is used to move the sealing member 18 in the axial direction and adjust the adjustable pressing force. It is connected to a regulating device (not shown) for adjustment.

In this embodiment, the piston-cylinder units 26, 27 can be used for various strip widths. The seal member can also be rolled into a roll to move the seal member axially for adaptation. It is also useful for crimping the roll 6. Separate drive devices are used to perform this work. You can also do it. In this case, the pivot lever I9 is driven electrically or hydraulically. The device is fixed for axial movement. The movement device is a pneumatic piston. It is connected to the sealing member 18 via cylinder units 26 and 27.

In a not-illustrated embodiment of the invention, a pivot arm holding seal member 18 is provided. The frame is bent.

In this case, the apex of the bending angle is located outside the range of the support rollers 2, 3.

A guide extending over the entire length of the support roller 2.3 is fixed to said apex. child A sealing member is movably supported on the guide.

This guide can therefore no longer be moved axially for adjustment to different strip widths. I can't move it.

After the new winding tube 11 has been placed on the support roller bed from above, the guide head 10 is I am forced to run in. Fix the starting end of the strip 4 to the winding tube and place the pressure roller on it to wind it. is started.

If the supporting load of the winding roll 6 is not sufficient for the desired winding hardness, additional pressure is applied. The pressure roller 26 presses the winding roll 6 toward the support rollers 2 and 3. Support load If the weight becomes too large, it is limited by the support roller 2.3 and the winding roll 6. Overpressure is eliminated by introducing pressurized air into the space. The load supported by the overpressure Weight is reduced. At this point, the winding roll 6 has a size of at least twenty minutes. diameter (approximately 800 mm), the winding tube 11 and, by extension, the carriage 9 have a sufficient diameter. Located above the support rollers 2 and 3 with a large interval and in contact with the sealing member 18 is avoided. The space limited by the winding roll 6 and the support rollers 2 and 3 is To do this, the air box 15 is first placed in the lower wedge-shaped position between the support rollers 2.3. The sides of the air box 15 are raised into the space with a narrow gap between the support rollers 2 and 3. It is then approached leaving behind and a downward seal is performed.

Then, the sealing member 18 on the end face side moves upwardly and inwardly against the end face of the winding roll 6. This allows the seal to be moved so that there are no narrow gaps left, and the seal can also be done on this side. be called. Pressure air is sent through the air box 15 and wound under the winding roll 6. The supporting load of the body roll 6 is reduced to a predetermined value.

In the embodiment shown in FIGS. 8 to 10, the air cylinder is first swiveled upwards. Pressure air is introduced from the box 15, and then the seal member 18 is inserted into the piston cylinder. The units 26, 27 are moved axially towards the end face of the winding roll 6.

In this case, the pressure at the piston 26 will not reach a force equilibrium if an overpressure is created. so that a slight gear is left between the sealing member 18 and the winding roll 6. controlled. In this way friction is avoided with minimal pressure losses. gap When the width increases or decreases, for example due to axial movement of the winding roll 6, The overpressure under the winding roll increases or decreases due to decreasing pressure losses. or rise. As a result, in the pneumatic piston cylinder unit 26,27 The pressure difference that forms with respect to the pressure applied to the Correct the tap width.

Alternatively, the small gap between the sealing element 18 and the winding roll 6 can be It is also possible to keep a small distance automatically adjusted for the position of the head 10. Ru.

Advantageously, the supporting load of the winding roll 6 is kept constant during the winding process. child In order to reduce the overpressure under the winding roll 6 from the desired support load by means of an adjustment or control device. is raised such that the increase in weight is offset until the end of the winding process. This is it Therefore, adjustment or control of the winding hardness is significantly simplified. Because the important influence value, i.e. the line load at both contact lines between the winding roll 6 and the support rollers 2, 3 This is because it no longer changes.

Alternatively, reducing the supporting load by creating a suitable overpressure reduces the supporting load to a specified level. It can also be done in stages to keep it within this range. Similarly, offset of increase in support load It is also possible to carry out the load reduction only partially or to reduce the load according to a predetermined function. Wear. Depending on the circumstances, it may be necessary to reduce the desired value once (no. is sufficient. The formation constitutes in each case one parameter for the control of the winding hardness of the winding roll 6. .

In the embodiment of FIGS. 8 to 10, the pneumatic piston cylinder unit 2 6.27 The pressure at It will be done. The distance between the sealing member 18 and the winding roll 6 is kept constant.

of the sealing surface in the upper wedge-shaped space and the lower wedge-shaped space between the support rollers 2.3; Instead of sealing with a labyrinth seal, a suitably selected outflow opening for pressurized air It can also be sealed with an air barrier through the mouth. Similarly, the labyrinth seal The effect can also be enhanced by supplying blocking air to the grooves of the labyrinth seal. support If the rollers 2 and 3 are placed very close together and rotate once, the slit nozzle is inserted from below. Even if you have pressurized air, it is sufficient to blow it into a narrow area. blown from below The compressed air reduces the loss caused by the extremely narrow gap between the support rollers 2 and 3. It also serves as a small air barrier, and is useful for sealing brushes, rubber lips, felt mounting bodies, etc. The friction between the support roller and the winding roll is sufficiently small. As long as you can keep it. In this case, the sealing member is attached to the roll without friction. contact with the roller 6 and support rollers 2 and 3, or where the pressure loss is so small that it can be ignored. The rollers 6 and the support rollers 2 and 3 are arranged at a certain distance from each other. child In this case, when sealing, the sealing member 18 is attached to both support rollers 2 and 3 with respect to each other. A frictional connection between the two support rollers 2, 3 is achieved without interfering with unrelated rotational movements. It is important that this does not occur. Otherwise, the necessary support load will affect the winding quality. The various torques of the rollers 2, 3 can no longer be adjusted to the required extent.
