Definitions
- TITLE A WINDING DEVICE, USE OF A ROLLER AND CORRESPONDING ROLLER
- Winding devices for paper sheeting are known in various designs, where rollers are in contact with the roll being wound parallel to its axis.
- the roll of the transportation roller rests on two parallel support rollers operating .at the same height and is driven from above by a drive roller.
- the roll on the backing roller is rotary seated on a shaft which, in turn, is mounted to pivot arms.
- the roll is in contact with a backing roller.
- the designs can have different details. But they all have in common, in connection with the invention, that an axis-parallel roller is in contact with the roll being wound, for example, in the form of the mentioned support rollers, backing rollers or driving rollers.
- nip pressure that is, the contact pressure of the roller against the roll being wound, is also responsible for the tensions in the sheet. If the roller in contact with the roll is practically inelastic, as is the case, for example, for a thick-wall steel roller, then the contact region is relatively narrow and is determined only by the flexibility of the roll itself. The contact force is then distributed onto a small surface, and the resultant specific pressure is large. The resultant stresses in the sheet then lead to a large package hardness that is often undesirable.
- rollers that is, rollers with a supporting cylindrical roller element at the outer perimeter; they have a coating made of rubber or another elastomer.
- the contact pressure not only is the roll deformed but also the material of the roller coating. Its shape adapts somewhat to that of the roll.
- the roll is to a certain extent pressed into the soft surface of the roller. This, then, will increase the contact area in the circumferential direction and reduces the specific contact pressure, which, in itself, is desirable.
- an axial stress on the paper sheet is created; this is not desirable because it affects the quality of the roll.
- Rollers with an elastic coating operating directly " against the roll thus, provide no advantages compared to the production of rolls of low hardness.
- the invention is based on the problem of designing a winding device so that it can produce rolls of lesser hardness, without affecting the other roll properties.
- the thin-wall rolling mantle is made of metal that is easily deformed in the circumferential direction; that is, it can be easily dented or depressed, and, thus, the desirable increase in the contact area in the circumferential direction and, thus, the reduction in specific contact pressure will be possible.
- the thin-wall rolling mantle made of metal is barely or not deformable in the axial direction, in contrast to an elastomer or even a rubber mantle, and thus does not affect the roll quality because no axial forces are produced.
- Rollers with an elastic, flexible intermediate layer and thin-wall metallic roller mantle are known.
- DE-GM 77 23 702 shows a rotation element designed with very small inertial moment about the longitudinal axis.
- This rotation element is to be used, for instance, as a towed diverter roller to guide sheet-like materials, such as textile sheet, paper sheet, metal foils and similar items.
- a cylindrical region with a low-density filler is provided which is surrounded by a metal mantle with a wall thickness of 0.03 to 0.5 mm forming the perimeter of the operating roller. It can be produced electrochemically or by rolling of metal foils.
- a roller with a roller element is known that is surrounded by an intermediate layer of filler containing bubble material, for example, foamed rubber materials or elastomers.
- a metallic roller mantle is located on the intermediate layer.
- the rollers should be used, for example, for calendering of textile products.
- the invention is also embodied in an application of a roller of the type described in Claim 2, as a supporting, backing or driven roller in winding devices for paper or similar articles.
- the intermediate layer consists of a compact, " elastomeric material with a Shore A hardness of 30 to 80°.
- the metallic, rolling mantle of the roller is best if made of steel (Claim 4) and can have a radial thickness of 1 to 5 mm (Claim 5) .
- a third aspect of the invention configured in the form of a single roller suitable for winding devises is given in Claim 6.
- the rolling mantle of the roller can be made of spring steel (Claim 7) because this steel has a particularly large range of elasticity and can adapt easily to the configuration of the roller without coming near the yield point.
- the sizing of the radial thickness of the intermediate layer depends essentially on the particular case. It must be thick enough to allow adaptation of the elastically deformable rolling mantle to the perimeter of the roll without generating excessive elongations. The thickness needed for this will depend on the contact pressure and on the diameter of the roll being produced. The range coming into consideration for practical applications lies between 10 and 100 mm (Claim 8).
- An important configuration of the invention consists in the fact that channels of at least 10 rnrn* ⁇ are distributed in the intermediate layer along the perimeter.
- the channels should have a macroscopic cross-section and not be designed as pores or similar features. They have a double function. First, they increase the flexibility of the overall configuration because the elastically flexible material of the intermediate layer—when the webs remaining between the channels are deformed, in turn, by the corresponding deformation of the roller mantle—can more easily escape to the side.
- the other function is a cooling function as described in Claim 10. During rotating of the roller, a considerable fulling work is performed in the material of the intermediate layer due to the deformation occurring for each revolution. Now, unless the proper precautions are taken, this fulling work will result in excessive heat-up of the elastic, flexible material. This is counteracted by the coolant.
- the grooves can be formed in the surface of the intermediate layer and can be open toward the interior of the roller mantle. This will make the production easier.
- the grooves can be provided as circumferential grooves, especially as screw-shaped perimeter grooves (Claims 12, 13) so that the coolant can be rather easily distributed over the entire circumferential surface. In multi-path designs, it is possible to move the coolant back and forth. If intersecting perimeter grooves are used, a waffle- or rhombic-shaped structure is obtained.
- the intermediate layer can be tapered axially outside the operating region from the roller mantle outward toward the axis in order to increase the fatigue limit of the apparatus.
- the paper are often filled with mineral strips and are ' abrasive, and, thus, the width of the nip in the circumferential direction of the roller may have local shifts of the paper sheet with respect to the perimeter, it may be a good idea to coat the roller mantle on the outer perimeter with a wear-reducing material, for example, a hard-metal coating (Claim 16).
- This type of coating also has the function of increasing the coefficient of friction between the roller mantle and the paper or other sheet material in order to transfer greater circumferential forces to the roll without increasing the contact pressure.
- Figures 1 and 2 show winding devices schematically in a cross-section running perpendicular to the axis of the rollers;
- Figure 3 shows a longitudinal cross-section through one end of the roller used as support, backing or driven roller
- Figure 4 illustrates the effect produced by the invention (greatly exaggerated) .
- FIG 1 we see a support roller roll-device (20) that is used to roll up a paper sheet (1) onto a roll (2) .
- the product sheet (1) is being moved forward under a certain longitudinal sheet tension and is diverted downward by means of a diverter roller (3) according to Figure 1. It rolls from below around driven support roller (4) with horizontal axis, next to which another support roller (5) of the same design, likewise with horizontal axis, is positioned at the same height and with little separation.
- the roll being wound (2) contacts the support rollers (4,5) at points (6) and (7) with a nip pressure (8) that is obtained from the weight of the roll and the contact pressure (9) of a driven roller (11) that is located above the support rollers (4,5) and symmetrically to them and stands under the force of one piston/cylinder unit (12).
- the driven roller (11) serves to guide the quickly revolving roll and to ensure a uniform formation of said roll.
- Figure 2 shows a support roller winding device where the product sheet (1) is being rolled up into a roll (2) that is not in contact with support rollers but rather is seated on a shaft on pivot arms (13) that stand essentially upright and are pivot-mounted at the bottom at point (14).
- rollers (4,5,11,16) are in contact in the nips with the nip pressures (8,9,17) at the roll (2), and due to their surface behavior, they determine the package hardness of roll (2).
- the rollers (4,5,11,16) are, thus, essentially of the same design and are given by rollers (10) whose inner design is visible in Figure 3.
- the roller (10) is composed of a cylindrical, hollow roller (21) in which a rotation-symmetrical end piece (22) is inserted at the ends, for example, it is welded in, and extends outward past the end of the hollow roller (21) and there forms the roller lug (23). These parts together form the roller element (24).
- the illustrated configuration is sufficient when the length of the roller (10) is not too large and the load is not too great.
- the hollow roller (21) can be a part of a hydraulic, internal-braced roller, for example, of a flexural-controlled roller according to DE-OS 22 30 139, for instance.
- the outer perimeter (25) of the roller element (24) is cylindrical.
- An intermediate layer (26) made of a compact, elastic, flexible polyurethane with Shore A hardness of 50° is attached to the outer perimeter (25).
- the wall thickness corresponds to that of the cylindrical roller tube (21) and amounts to about 30 mm.
- the two-screw threads formed by the perimeter grooves (27) or (28) are connected by means of connecting holes (29,31) to a central drilled hole (32) in the roller lug (23) through which a coolant, for example, air or water, can be fed, which is pumped through the perimeter grooves (27,28) from left to right in Figure 3.
- the roller (10) is appropriately designed at the right end and contains a drain line there for the coolant.
- Other liquid lines are also known. It is important only that the perimeter grooves (27,28) be distributed uniformly along the perimeter and that they be relatively closely packed together.
- the cylindrical, outer perimeter of the intermediate layer (26) is covered by a thin-wall roller mantle (33) of spring steel of about 2 mm radial thickness that is braced against the intermediate layer (26) and covers it over its entire surface.
- a thin-wall roller mantle (33) of spring steel of about 2 mm radial thickness that is braced against the intermediate layer (26) and covers it over its entire surface.
- the downward open grooves (27,28) that have an essentially rectangular cross-section with rounded bottom are closed off on the outside by the roller mantle (33).
- roller mantle (33) rests essentially over the entire length of the roller and is securely touching the intermediate layer (26). But at the ends, the outer perimeter of the intermediate layer (26) moves inward at (26') away from the inner perimeter of the roller mantle (33). This feature is used to increase the flexibility and to prevent destruction due to edge effects.
- the outside of the roller mantle (33) has a coating (36) of hard metal in order to counteract the long-term, abrasive effect of the paper sheet (1) and to increase the coefficient of friction between the roller mantle (33) and the paper sheet (1) .
- the effect of the invention is shown in Figure 4 (exaggerated).
- the roller (10) is relatively easy to deform in a plane perpendicular to the axis because the roller mantle (33) is made of thin, spring steel and is only elastically supported by the intermediate layer (26).
- the roller mantle (33) is, thus, pushed in somewhat in the manner shown in Figure 4 and touches the perimeter of the roll in the nip in a contact area (35) which is relative broad, due to the contact; at any rate, it is broader than it would be for an entirely rigid counter-roller.
- the contact force occurring per length unit is thus distributed to this relatively large contact area (35) so that a rather low, specific nip pressure is generated which will assist in the formation of a low package hardness, which, in many cases, is desirable.
