Definitions
- the invention relates to a roll winding device two carrier rollers that hold a changing bed for one Form winding roll, and a compressed air support device, which a Druckkanueran extract with end face sealing elements having.
- the invention is intended to be exemplified below with reference to Paper rolls are described. But it is not open limited this application.
- paper webs In one of the last manufacturing steps, paper webs usually cut to the correct width and then wound up in rolls before packed and shipped.
- the winding cores on in contrast which the paper rolls are wound up to those used during paper production Drums only a relatively low stiffness and Load capacity. They are often designed as cardboard tubes. This causes the paper rolls to wrap usually supported by support rollers. This is particularly pronounced when the Winding device is designed as a support roller winder. Here the roll rests on carrier rollers without additional Attack holding forces on the core. But also with a backup roller roller with additional holding means there can be an attack on the roll core on a roller. If the paper rolls are bigger and the support line forces of the paper roll become heavier on the carrier roller or rollers relatively large, what has the disadvantage that this increases the winding hardness becomes. This can later lead to an error in the winding structure the role. To relieve the roles and To reduce the line force, a pneumatic Overpressure are generated below the roll, so that at least part of the roll weight of an air cushion will be carried.
- the Carrier rollers used. Below is the support roller Sealing plate or a sealing box arranged.
- the paper roll itself serves as a seal.
- the seal On the face of the paper roll is the seal the current constructions made that a sealing plate with adapted to the contour of the changing bed Shape as close as possible to the front of the Paper roll is positioned.
- the sealing plate would in such cases also wear out very quickly. For this reason, leave a distance of several millimeters between the face of the paper roll and the sealing plate. It is obvious that there is air through this gap escapes in considerable quantities.
- the invention has for its object the air consumption to keep small.
- This task is done with a roll winding device of the type mentioned in that at least an end sealing element one with the circumference the sealing roller arrangement interacting with the winding roller having.
- sealing Location namely the end face of the winding roll
- relocated the location of the seal on the peripheral surface of the Winding roll This has several advantages.
- the circumferential surface of the winding roll is generally significant smoother than her face.
- one the sealing diaphragm arrangement with an essential Position a smaller distance from the circumferential surface of the winding roll.
- you can the axial extent of the sealing diaphragm arrangement somewhat choose larger, so that this results in a greater flow resistance for the escaping air is formed. Accordingly, by the extent of the Wrapping roller-acting sealing screen arrangement less air escape than with a seal with the face the winding roller interacts.
- the term "Sealing diaphragm arrangement" is not intended to be plate-like Be limited. It basically includes everyone Body or parts that match the circumference of the winding roll interact and thereby escape the air prevent or at least make it difficult at the end faces. Of course, it is also on the scale of Winding roller acting seal with reasonable effort practically impossible to get a hermetic seal achieve. This is because, for example, that here a seal against three moving parts made must be, namely opposite the two support rollers and the winding roll. By the invention Measure, the air consumption can still be small hold.
- the sealing diaphragm arrangement and are preferably at least a support roller height adjustable relative to each other. This takes into account the fact that the diameter of the winding roll changes during winding. There the support rollers a constant distance relative to each other the change in diameter leads to that the winding roll keeps getting out of the changing bed lifts out, i.e. less with a larger diameter plunged deep into the changing bed. If the seal assembly is adjustable in height, then you can despite this change in the sealing geometry always the desired maintain a small sealing gap. this applies even if the axes of the support rollers are not in the same level or the diameter of the Carrier rollers are uneven.
- the sealing diaphragm arrangement has a sealing panel with a variable shape.
- the Ratios of increasing diameter Take into account. If the diameter of the winding roll enlarged, then a larger one is created on the front "Window" through which air could escape. Man can change the shape of the sealing diaphragm continuously or from time to time to adjust so that you can this window as possible covers well.
- the width of the Sealing diaphragm is changeable. With increasing diameter the winding roll migrate the support points of the Winding roller on the support rollers away from each other. If changed the width of the sealing panel, then you can Follow the contact points of the winding roll on the support rollers and thereby keep the opening through which the Air could escape.
- the vertical distance from the ends to the center of the Sealing diaphragm is changeable.
- the Sealing diaphragm the cross section the shape of a flat V have, the opening angle with increasing Roll diameter increases.
- the shape of the sealing diaphragm is preferably a function the height setting can be changed.
- a given Carrier roller geometry results in the shape of the to be sealed Opening depending on the increasing winding roll diameter.
- the growth of the winding roll diameter has two consequences, as I said. For one thing, it wanders lowest point of the winding roll circumference steadily upwards, so out of the changing bed. On the other hand, they hike Support points of the winding roll on the support rollers Outside.
- the sealing panel as close as possible to the circumference of the To keep winding roll, one can get the information on the "Altitude", ie over the vertical position of the Sealing cover, use at the same time, also for predefined a specific winding roll diameter Shape, for example a predetermined width.
- the sealing panel from several, against each other movable parts is formed. If you look at the parts moved relative to each other, the shape of the Change the sealing panel in a simple way.
- the parts are relative are displaceable or pivotable relative to one another. With the width can be shifted, for example change the sealing panel. The only requirement is that that between parts of the sealing panel there is some overlap so that when moving no new openings are formed.
- each part is opposite one Lifting device in a first guide and opposite a fixed bracket in a second guide is.
- the first Leadership allows the movement relative to the lifting device to.
- the second guide controls the sideways movement.
- At least one of the two guides designed as a linear guide. Leave linear guides easy to manufacture. The danger that the part jammed or jammed, is relatively small.
- two parts of the sealing panel designed as a pivot lever are.
- swivel levers it is also possible the changing altitude of the lowest point of the To follow the circumference of the winding roll. Are swivel levers relatively easy to control.
- each pivot lever extends approximately from one support roller to the other and has a stationary pivot axis at one end.
- the two swivel levers together cover at least approximately the entire width of the changing bed. With width is the distance between the two support rollers meant. Cross over due to the arrangement of the swivel axes the two swivel levers when lifting, so that the formed by both swivel levers together, common lowest point the circumference of the winding roll can follow.
- the sealing diaphragm arrangement is preferably on one End wall of the pressure chamber assembly attached.
- This Front wall can already cover most of the cross section cover that freely between the support rollers remains.
- the front wall can thus extend up to one position extend up to which the winding roll at her smallest diameter to support, usually about 800 mm.
- the sealing diaphragm arrangement must then only the larger roll diameter cover the resulting cross section.
- the front wall offers In addition, there is also an inexpensive fastening option.
- the end wall is preferably parallel to the support rollers movable.
- a compressed air support for the winding roll only from certain roll diameters, for example the 800 mm mentioned above is necessary you can already make a relatively large one with this measure Cover cross section of the pressure chamber arrangement without that one disturbs the structure of the winding roll.
- the Front wall moved away from the winding roll. Only at; only when a larger diameter at which the lowest point the winding roll is lifted out of the changing bed far enough the front wall is provided. First to this At the same time, pressure is also applied and accordingly is only a seal at this time necessary.
- the sealing diaphragm arrangement preferably has a Tracking device with a drive and a sensor for the position of the winding roll.
- the drive serves to raise the seal assembly so that it the changing position of the winding roll circumference consequences. So that the sealing panel arrangement always
- the winder roll sensor can stay as close as possible to the circumference intended. He reports back to the drive if the seal assembly is on one has approximated the predetermined value to the circumference. If this state is reached, then the drive interrupts the further lifting of the sealing panel arrangement.
- the winding roll sensor can be used in several different ways Be trained types. You can use it, for example, without contact let work, for example pneumatic, capacitive, inductive, optical or with a laser scanner. In In this case, the Drive possible.
- a roll winding device 1 of which only for Explanation necessary section is shown has a first support roller 2 and a second support roller 3, which form a changing bed 4 between them.
- a winding roll 5 In the winding bed is a winding roll 5.
- This winding roll is shown with a circumferential line 6 for one smaller diameter and a second circumference 7, which results when the diameter of the Winding roll has increased.
- the second circumferential line 7 has less curvature.
- the changing bed 4 is not shown in detail also sealed down.
- an air supply port (not shown) provided, fed via the compressed air into a room can be that of the support rollers 2, 3, the Winding roll 5 and the end walls 8 (on the opposite Side of the winding roll is also located such an end wall) is limited.
- the end wall 8 ends at the top, i.e. on the of the winding roll 5 adjacent side, at a height up to which the Circumferential line 6 of the winding roll 5 is sufficient. This circumference arises when the winding roll 5 a Has reached diameter, from which a compressed air support necessary is. This diameter is in many cases in the order of about 800 mm.
- winding roll 5 has a diameter that is represented by the circumferential line 6, then lies them at a first point 9, more precisely along a axially parallel line 9, on the support roller. If the diameter has increased so that the winding roll 5 has the circumferential line 7, then shifts the edition becomes a line 10. The same applies of course also for the other carrier roller 3.
- the end wall 8 covers, as stated, the largest part from the front of the clear space, which through the Carrier rollers 2, 3 and the winding roller 5 is formed. It there remains a small opening 11, but in practice is not critical. A hermetic seal of this In practice, space is anyway with reasonable effort not possible and as long as the leak in certain Limits remain, also not necessary. More critical however, would be the enlargement of the opening itself when changing the circumference of the winding roll 5 results. This opening could then take on sizes through which a lot of air escapes.
- the seal panel assembly has a carrier 13, which is by means of a lifting cylinder 14 can be raised from a dashed line position 15 shown in the with solid Line represented position.
- a sealing diaphragm 16 is arranged on the carrier 13, which interacts with the circumference of the winding roll 5.
- the sealing panel 16 is a sensor 17, the is designed here as a contactless proximity sensor and generates a signal when the winding roll 5 is in a distance from the sealing panel 16 is one falls below a predetermined value, for example 0.5 mm.
- the sensor 17 is with the lifting cylinder 14 or its Control connected.
- the lifting cylinder is controlled that the sealing panel 16 always as close as possible Scope of the winding roll 5 remains.
- a roll core for example a cardboard tube, inserted into the changing bed 4.
- the support rollers 2, 3 rotates the winding core and pulls a material web on itself. With these coils the diameter and increases the winding roll 5 gradually moves upwards.
- the end walls 8 are retracted axially and until the sealing panels 16 are below the winding roll 5 are located and expediently complete with the end of the winding roll 5 or survive slightly. On the exact axial adjustment it does not matter in the present case.
- the lifting cylinder 14 lifts the carrier 13 for as long as until the sensor 17 signals that the sealing panel 16 is almost on the circumference of the winding roll 5.
- the sealing panel 16 can be one Have apron 19 which interacts with the end wall 8, to prevent an opening underneath it arises.
- the carrier 13 has a longitudinal slot 20 in engage the two bolts 21, 22 to a vertical Ensure leadership of the carrier 13.
- the carrier 13 is supported via rollers 23, 24.
- the sealing panel 16 on a Carrier may be arranged, which has the shape of an inverted U has, which is guided on a guide rail is.
- plain bearings can also be used. Basically comes any known type of leadership in question, one vertical guided movement of the sealing panel 16 allowed.
- FIG. 1 increases the Opening 11 with increasing roll diameter.
- Fig. 2 shows a modified embodiment of a roll winding device 1 ', in which this phenomenon largely is avoided.
- the same parts are the same Provide reference numerals. Modified parts are provided with deleted reference numerals.
- the sealing panel 16 ' is divided into two in this embodiment. For the sake of clarity is in the front view 2 only the left half, ie a part, the sealing panel 16 'shown. The presence of however, two sealing panels result from the sectional view (right).
- the carrier 13 ' is arranged on a lifting table 26, in the guide 25 under the action of the lifting cylinder 14 is vertically displaceable.
- the carrier 13 ' has here a horizontally running slot 27, in the bolts 28, which are attached to the lifting table 26, intervention. Accordingly, the carrier 13 'and thus the sealing panel 16 'in the width direction (i.e. in Direction from one support roller 2 to the other) the lifting table 26 can be moved.
- the sensor 17 ' is this time by a "sliding block" formed, which abuts the circumference of the winding roll 5 and is accordingly designed as a pressure sensor. If the pressure on the sensor 17 'subsides, then the Lift cylinder 14 on the lifting table 26 so that the sealing panel 16 'also raised and moved apart becomes. This change in shape makes it possible to change the area the leakage even with larger reel diameters to keep small. Of course, instead of Glide stones also other touching or non-contact Sensors can be used.
- the lifting table can also be U-shaped guide 25 between rolls. You can use the bolts 28 also provide on the carrier 13 'and in the lifting table 26 therefor make the slot. In the same way it is possible, the bolt 30 not on the carrier 13 ', but on Provide housing 25 when a functionally equivalent Slot 29 is then provided on the carrier 13 '.
- a push button switch can also be used use the always an actuation signal the lifting cylinder 14 sends when the winding roll around more than a predetermined distance from the sealing panel 16 'away.
- the course of the guide 29, 30 can also deviate from a straight line when lifting movement and extending movement have no linear relationship to each other. But a straight line becomes even if not necessarily corresponds to the ideal course of the control curve in will suffice in most cases.
- Fig. 3 shows a third embodiment in front view or in sectional view, with the same parts with the same Reference signs and corresponding parts with double deleted reference numerals are provided.
- a sealing panel 16 ′′ that changes shape with increasing roll diameter.
- the sealing panel 16 '' consists of two levers 32 which in the rest position from one support roller 3 to the other Extend support roller 2. The runs in this rest position Top of the pivot lever 32 in this embodiment practically horizontal. But it is obvious that one already adapts to the curvature of the peripheral surface the winding roll 5 can make.
- the pivot lever 32 is on a pivot axis 33 in the Near the support roller 3 pivotally mounted.
- the lifting cylinder 14 acts on a bolt via a lifting table 26 34, which is arranged in an elongated hole 35 in the pivot lever 32 is in half of the pivot lever 32, which is not connected to the pivot axis 33. If now the lifting cylinder 14 lifts the lifting table 26, then the inclination of the pivot lever 32 is changed. The left tip 31 '' is raised and follows the lifting peripheral surface of the winding roll 5. Dashed the right swivel lever is also shown 32A. He is moved to the same extent by a movement of the lifting cylinder 26 is also lifted. Accordingly, also the "crossing point" 36 of the two pivot levers 32, 32A hike up. That way too to ensure that the gap that is not covered by the End wall 8 is covered, remains small.
- sealing diaphragm arrangement 12 shown, 12 ', 12' ' each consisting of one or more rigid Parts are formed
- a hose with compressed air or another Pressurized fluid is inflatable.
- Such a hose is then initially, i.e. at the start of the wrapping process up to a diameter of the winding roll of approximately 800 mm flush with the upper edge of the end wall 8, i.e. the Edge facing the roll. If with growing Roll diameter a gap arises, the Inflated hose. If the hose on the roller circumference this gap is sealed.
- the side of the roller against the roller Hose or air cushion is then preferred provided with a friction-reducing coating.
