Description

Packaging unit for a glass rolled onto a winding core

description

The invention relates to a packaging unit for a rolled on a winding core glass and the use of such a packaging unit.

For a variety of applications such as in consumer electronics such as covers for semiconductor modules, for organic LED light sources or even thinner display devices or in areas of renewable energy or energy technology, such as solar cells is increasingly used thin glass. Examples include touch panels, capacitors, thin-film batteries, flexible printed circuit boards, flexible OLEDs, flexible photovoltaic modules or even e-papers. Thin glass is becoming more and more of a focus for many applications due to its excellent properties such as chemical, thermal shock and heat resistance, gas tightness, high electrical insulation capacity, adjusted coefficient of expansion, flexibility, high optical quality and light transmission or high surface quality with very low roughness due to a fire polished finish Surface. Under thin glass are here glass plates, glass sheets, glass substrates or glass sheets understood with thicknesses less than about 1, 2 mm to thicknesses of 15 μιτι and smaller. Due to its flexibility, thin glass is increasingly being rolled up after production and stored as a glass roll or transported for packaging or further processing. The rolling of the glass involves the advantage over a storage and the transport of flat spreading material the advantage of a more cost-effective compact storage, transport and handling in further processing. To further reduce transport and storage costs, it is advantageous to wind as tight radii as possible, whereby, however, the tensile stresses in the glass band and thus the risk of breakage are increased.

Despite its outstanding properties, glass as a brittle material has a rather low breaking strength because it is less resistant to tensile stresses. For a break-free storage and for a break-free transport of such a glass roll, first of all the quality and integrity of the edges is important in order to avoid the occurrence of a crack or break in the rolled up glass ribbon. Even damage such as tiny cracks, e.g. Micro-cracks can be the cause of larger cracks or breaks in the glass ribbon. When rolled up, the top of the glass ribbon is under tension, and further, integrity of the surface of scratches, ridges, or other surface defects is important to avoid cracking or cracking in the rolled-up glass ribbon. Third, manufacturing-related internal stresses in the glass should be as small as possible or not present in order to avoid the occurrence of a crack or breakage in the rolled-up glass ribbon. However, since all three factors can only be optimally optimized in a commercial production, the susceptibility to breakage of such a rolled-up glass is further increased to the limits of its material properties that are present anyway. Thus, special precautions and conditions are important for the storage and transport of such a glass roll to avoid damage to the glass. In particular, such a glass roller must be protected from shocks and vibration-like loads. Such external mechanical stresses can otherwise lead to exceeding the breaking point of the glass and thus to cracking in the glass.

For example, if a glass roll in a position in which the axis is approximately horizontal, stored on a storage surface such as on a pallet, that is Problem that it comes to a concentration of stress in the contact area and easily arise in the glass ribbon breaks.

The storage, transport and handling of flat expanded glass materials is necessary for thicker glasses that have too low a flexibility for rolling, such as flat glasses and known glasses for flat screens. For example, US 2007/0131574 or JP 048577/1990 describes a packaging for such extensively spread glass materials. However, such a package is not compact and totally unsuitable for packaging a glass roll.

The packaging of a rolled-up material on a roll, in contrast, describes WO 2008/123124. Here, a plate-shaped flange is described with an attached tubular part, which engages in the cavity of a winding core to protect against shocks for both sides of the roll. The two parts should each integrally formed from a polyolefin bead foam, which is to absorb the impact energy. Furthermore, a gap is provided between the upper edge of the rolled-up material and each flange as edge protection. However, such a package is unsuitable for a glass roll, since the glass roll would be completely unprotected in its surface propagation between the flanges and, secondly, in spite of the space provided and the material selection for roll support, vibration and impact energy would be improperly absorbed Glass registered. Also no safe way for storing and transporting many glass rolls is provided.

In a further development, JP 2009-173307 describes, for the storage and transport of a sensitive pressure measurement sheet rolled up onto a winding core, a packaging form in which a flange is formed at both ends of the winding core on which the pressure measurement sheet is wound greater than the outer diameter of the wound pressure measuring arc. As a result, the pressure measuring arc is brought to a distance from the shelf. Now, unlike a pressure gauge, a glass film is a material that is easily broken. That is, with a pressure gauge, it is sufficient to make sure that the microcapsules formed on the surface do not burst for pressure measurement, but with a rolled up glass, it is necessary to make sure not only on the surface of the roll but also on the surface The edges of the glass ribbon, which form the lateral areas of the roll, no fractures arise. In particular, since the two lateral areas of the roll may be exposed to the outside with the edges of the glass ribbon, they easily become the starting point for breaks at the edges.

Here, WO 2010/038760 describes a further development for a glass roll. For a glass roll with side flanges rolled up on a winding core, various arrangements for buffering with introduced buffer materials between the lateral regions of the glass roll and the flanges will be described. This is to contact the edges of the glass ribbon with the flanges, which could lead to fractures on the edges to be avoided.

For this purpose, laterally projecting intermediate layers curled between the glass tape layers are proposed, which fill only a part of the intermediate space and are not in contact with the flanges or which are in contact with the flanges in another proposed embodiment. However, cracks or breaks in the glass ribbon or at the edges may occur during winding or unwinding of the glass roll when the protruding areas of the intermediate layer become caught or caught. It can also come through shocks or vibrations during transport to a lateral displacement of the glass ribbon layers on the roll, which also leads to fractures of the glass ribbon or edge damage. A lateral pushing the glass ribbon here can be done as a whole along the axis direction of the winding core or by the outer diameter side of the glass ribbon on the roll with respect to the inner diameter side moves laterally and the edges of the glass ribbon then stepwise over each other (lateral "telescoping").

In another embodiment, a separate buffer material is placed between the glass roll and the flange. As a result, although a lateral displacement of the glass ribbon layers on the roll could be reduced by impacts or vibrations during transport, but it comes in particular with transport-induced vibrations to a relative movement between the glass band edges and such a buffer material. Even with very small relative movements or stresses caused thereby at the edges of the glass ribbon, these can be damaged or cracks are induced in the glass ribbon.

To avoid this, it is proposed in another embodiment to arrange this buffer material only in contact with the flange, but not in contact with the lateral areas of the glass roller. As a result, however, it can in turn come through shocks or vibrations during transport to a lateral displacement of the glass ribbon layers on the roll as a whole or to the described lateral telescoping, which in turn can cause fractures of the glass ribbon or edge damage.

Furthermore, WO 2010/038760 describes the formation of axle parts which project laterally from the flanges and are supported by bearings which are formed in sockets. This is intended to prevent rolling of the glass roller independently of the flanges. Also, such a structure or a plurality of such structures can be covered by a packaging box. A disadvantage of this solution, however, is that shock and vibration-like loads are transmitted to the glass roll without damping, which represents a high risk of breakage and cracking of the glass. As an alternative to this package with transversely directed glass roll, a package with vertically directed glass roll is described. Here are several glass rolls to be placed with their winding cores on perpendicular columnar elements, which are attached to the bottom of a box body. The disadvantage here, however, on the one hand, a wobbling of the glass rolls during transport. Although a sufficient spacing of the glass rolls or the filling of a buffer material between the glass rolls is proposed to prevent thereby caused fractures of the glass sheet, the edges, which are located on the footprint of the glass roll, not only by the autogenous pressure of the glass roll but in particular stressed by the shaking of the role in an inappropriate manner, which leads to cracks and breaks in the glass ribbon and edge damage. On the other hand, shocks and vibration-like loads are also transmitted undamped to the glass roller or introduced into the glass roller, which represents a high risk of breakage and cracking of the glass.

The object of the invention is thus to avoid the disadvantages described above and to provide a packaging unit for receiving a rolled-up on a winding core glass, which reduces the risk of breakage and cracking of the glass during storage or transport. Also, a secure packaging for several glass rolls to be found.

The invention solves this problem with the features of claim 1 and claims 12 and 13.

The glass roll is integrated into a closed packaging unit to protect it from direct external physical or chemical attack or impact. Such a packaging unit consists of at least two separable wall parts wherein the wall parts together result in a closed unit. The individual wall parts of the packaging unit are differentiated as follows: The two head parts of the Packaging unit, which are arranged opposite the lateral areas of the glass roller and the wall parts, which include the width orientation of the glass roller, such as the bottom part, the side parts and the cover part of the packaging unit. The packaging unit can be rectangular or polygonal or cylindrical.

For example, all wall parts of the packaging unit can be assembled together as individual parts in the packaging, or they can also be joined together as individual groups so as to be firmly joined together in the packaging.

In a preferred embodiment, the side parts, the bottom part and the cover part or the cylindrical wall part are connected to a head part, whereby only the other head part is connected to the other parts in the packaging of the glass roller to form the packaging unit. But it can also be connected to each head part in each case half the length of the side parts, the bottom part and the cover part.

In a cylindrical embodiment, the bottom part, the side parts and the cover part form a hollow cylinder, which individually forms a wall part and is joined together with two head parts or is already completely connected to a head part and is joined together with the second head part or in each case as part of both head parts may be connected, wherein the assembly always creates a closed packaging unit.

As material for the wall parts of any material is suitable, which ensures sufficient stability, such as a wood, laminated wood, metal or plastic. Depending on the transport or storage requirements, adequate gas tightness or environmental resistance is taken into account in the selection.

With the wall parts, which form the head parts, according to the invention, in each case a holding element is connected. The retaining elements are opposite arranged and carry in use the glass roller or the winding core between them, so that a glass roller spaced from the wall parts, which form the bottom part, the side parts and the cover part, can come in the packaging unit for storage.

A holding element can be directly connected to a wall part and anchored in or on this. But it can also be an anchorage for the holding element associated with a wall part. The anchoring can be firmly connected to the wall part or only loosely in contact with this. For example, the anchoring can be positioned as a separate component in front of a head part and positively or non-positively connected to this and / or the adjacent wall parts. In any embodiment, the anchorage in the closed state of the packaging unit is firmly connected thereto.

The anchoring may be formed of two spaced-apart plates, which may be braced together, if desired, to form a strong anchorage for a holding element which can receive and support a glass roll without the second holding element. However, an anchoring can also be attached, for example, as a reinforcing plate on the inside of a head part and carry the holding element.

Such a holding element may for example comprise a pin, a mandrel, a pin, a lock or a closure, which are each suitable for being able to engage in a corresponding connecting device at one end of a spindle mandrel, wherein both holding elements the winding core with the optionally on it wrapped glass can safely hold between them.

In a preferred embodiment, in this case, a holding element is designed so that it can engage in a winding core arranged in the cavity or in a corresponding recess, the or each on the lateral Ends of a winding core is provided. The engaging part of the retaining element, which may be a support mandrel or one or more pins or pegs, may have any suitable cross-section.

A winding core can be round or polygonal. For example, a winding core essentially consist of a tube, so that the holding elements can engage in the lateral tube ends. The holding elements can have a conical region which is suitable for centering the winding core. Also, the lateral ends of a winding core may have one or more determined shaped recesses into which mating counterparts engage the retaining elements and preferably center the winding core thereby. Such recesses may, for example, be cone or frustoconical or pyramidal or truncated pyramid shaped or designed in any other suitable manner. Also, a particular connection device can be provided at one or both ends of a winding core, which can be anchored to a respective counterpart on the holding element, so that the winding core can be securely connected at its lateral end to the holding element. Such a device may for example be designed as a bayonet closure or have a device for locking, hooking, locking or screwing.

In a preferred embodiment, a continuous support mandrel is provided for a substantially tubular winding core which extends along an axially extending cavity in the interior of the winding core and on which the winding core rests substantially over its entire inside length and is supported. In one embodiment, the carrying mandrel is fixedly connected to a holding element and associated with it and is connected or anchored during assembly of the packaging unit with the second holding element. When the packaging unit is assembled, the carrying mandrel can also be connected as a separate component to each holding element or anchored. The connection or anchoring can be done for example by inserting or screwing into a pin or in any suitable manner.

The cross section of the support mandrel can be round in the simplest case, wherein a single axially extending support surface for the winding core is formed when the support mandrel diameter is smaller than the inner diameter of the winding core. However, by suitable cross-sectional selection, two or more axially extending bearing surfaces may also be provided, thereby improving the support of the winding core. As a result, the deflection of a stored or transported glass roller can be effectively reduced or prevented even in the long run and in shocks and vibrations.

In another embodiment, a support mandrel can also be fastened or anchored to each retaining element or can be fastened or anchored during assembly of the packaging unit. In order to be able to support and support a winding core or a glass roll with a winding core, in use the two support pins project from the lateral ends of the winding core into it. This can be so far that they almost touch each other or even extend only in the lateral end region of a winding core.

In another embodiment, a continuous support mandrel or a support mandrel is the component of a holding element or even the part of a holding element engaging in a winding core can be designed such that it can be braced in the winding core. For example, it can be designed as an adapter or as a clamping head or as a clamping adapter for bridging the different diameters of the winding core and support mandrel or of the part of a holding element engaging in a winding core. This ensures a solid support with maximum support surface against deflection even under heavy loads. Also, the glass roller can not on the bracket, at- For example, swing a support mandrel or take off, which allows a maximum safe transport.

In a further embodiment according to the invention, a damping element is connected to at least one retaining element and / or with at least one wall part. Damping elements damp vibrations, vibrations or shocks in all possible spatial directions. They are intended to reduce or completely absorb the transmission of vibrations and shocks during the handling, storage and transport of the packaging unit from outside to inside the glass roll. As a result, the entry of shocks and vibration-like loads on or in the glass roller is effectively reduced to a level that allows safe transport or storage of a glass roller.

Impacts can be caused in various ways by transportation with a vehicle or by improper handling of the packaging unit or by bumping in any way and are impulsive loads that may not be transferred by the packaging unit to a dangerous level on a glass roll.

Vibrational loads are frequency-dependent in their manifestation. These include periodic loads, e.g. rather a short-frequency oscillation in the range 0.1 Hz to 20 kHz, in particular 50 Hz to 10 kHz, as they are transmitted during transport, for example, by vibration or vibration of an engine on a glass roll to be transported and can lead to damage.

Another burden would be centrifugal forces, acceleration forces or braking forces, which can act on a glass roller during transport.

According to the invention, the packaging unit has one or more damping elements which damp the shocks or vibrations and reduce transmission to the glass roller to a level which ensures safe transport. the safe storage of a glass roller allows. A damping element is connected to at least one retaining element or at least one wall part, or an anchoring associated with a wall part. Any conceivable combination of the individual embodiments is possible and is in each case combined so that overall for all expected loads optimum protection of the glass roller to be transported is made possible.

In one embodiment, a damping element is arranged in at least one wall part, which encloses the holding element in the region of its anchoring in the wall part or the anchorage itself, wherein the anchorage forms part of the head part. In this way it can be effectively prevented that shocks or vibrations, which act primarily perpendicular or oblique to the axis of a holding element, are transmitted via the holding element into a glass roll to be transported. But it can also be damped shocks or vibrations, which act parallel to the axis of a holding element.

In a further embodiment of the invention can be provided that on the outer surface of at least one support pin of a holding element, which also be designed as a pin or pin no, at least partially and at least partially enclosing one or more damping elements are arranged, which vibrate in use a winding core and shock absorbing connect with the holding element. For example, these may be one or more spaced elastic damping rings. But it can also be one or more axially extending damping elements. As a result, it can be effectively prevented that shocks or vibrations, which act on the packaging element, are transmitted via the holding element into a glass roll to be transported. In a further embodiment according to the invention, provision can be made for one or more damping elements to be arranged at least on the outer surfaces of a carrying mandrel passing through the winding core, at least partially and at least partially surrounding it. The damping elements may in this case be arranged, for example, only in regions at the lateral ends of a winding core, or even distributed over the entire length. For example, this may be one or more elastic damping rings. Also, the entire surface of the support mandrel may be coated or surrounded with a vibration-damping material. Also, the support mandrel total consist of a vibration-damping material. In use, as a result, the mass of a winding core is stored with a rolled-up glass vibration and shock absorbing on the support mandrel or the holding elements. As a result, it can be effectively prevented that impacts or vibrations, which act on the packaging element, are transmitted via the holding elements and the carrying mandrel to a glass roll to be transported.

In a further embodiment of the invention, the support mandrel is spring-mounted or vibration-damped in the holding element. The damping element forms in this embodiment, the support of the support mandrel in the support member, wherein the support mandrel may be a continuous or a non-continuous support mandrel or in the execution of one or more pins or pins.

For example, in one embodiment, the damping can be embodied such that the carrying mandrel, pin or pin, except for the actual main bearing, hangs on two springs and is supported by two shock absorbers. This allows it to vibrate, but is braked gently at too large deflections by the shock absorber.

In a further embodiment according to the invention it can be provided that on the outside, preferably below the bottom part of the packaging ckungseinheit, one or more damping elements are arranged. For example, if a damping element attached to the outside of the bottom part, it forms the support surface of the packaging unit, for example, on a pallet. It can be mounted on the outside of the bottom part of several surface or selectively distributed damping elements, for example as buffer elements or shock absorbers in the corner regions or as a strip on two opposite lateral areas. Also, the entire bottom surface may consist of a layer of a vibration-damping material. Such damping plates may consist of cork, rubber, rubber-metal compounds or equivalent. Preferably vibration damping mats or vibration damping plates are used for this purpose. In this way it can be effectively prevented that shocks or vibrations, which act from below on the packaging unit, are inadmissibly transferred to the packaging unit and are transmitted via the latter into a glass roll to be transported.

Against lateral impacts or shocks from above or against transmission of vibrations when assembling a plurality of packaging units damping elements can be arranged at any point on the outside of the packaging unit, where appropriate.

The damping elements can in this case cover the entire outer surface of a wall part or only larger or smaller areas.

Since the packaging units according to the invention can also be stackable or can be assembled in a manner to form a larger packaging unit, according to a further embodiment of the invention on the outer sides at locations where the individual packaging units touch, preferably on the footprint or the shelves be arranged below or above or on a contact surface side of the packaging unit, one or more damping elements. As damping elements, for example, buffer elements or shock absorbers come from an elastomer such as rubber, silicone or rubber or

Foam or elastic springs, in particular rubber springs for use. However, it is also possible, for example, to use damping elements containing metal mesh or gas-damped elements. According to the invention, it is possible to use all suitable damping elements which are sufficiently known to the person skilled in the art. Depending on the specific task on a damping element, the deformation path and the damping can be selected smaller or larger by suitable shape and / or material selection. In the dimensioning and dimensioning of the damping elements in each case to be resilient or damping mass of the glass roller or the packaging unit is taken into account. In one embodiment, these are gas pressure damping elements which make it possible to adjust the damping via an adjustable gas pressure in each case to the mass of the glass roll to be packed.

In all cases, a swing in the natural frequency of the mass to be packaged should be counteracted or avoided

In a further embodiment according to the invention, it can be provided that, for the packaging of a plurality of glass rolls, at least two packaging units can be arranged one above the other and / or next to one another, assembled into one another like a module. For this purpose, arranged on the footprint or the shelves below and at the top of the packaging unit and / or laterally cooperating receiving devices for a further packaging unit. The receiving devices can cooperate in a form-fitting manner by, for example, providing a corresponding depression on a packaging unit, in which an elevation of another packaging unit engages. The receiving devices can also cooperate non-positively by ner recording device are firmly locked together or can be firmly connected to each other in any suitable manner.

In one embodiment of the invention, a damping element is arranged on the surfaces of the receiving device, where both packaging units are in contact.

In a further embodiment of the invention can be provided that the packaging unit is sealed gas-tight and the interior is filled with a clean gas. As a result, a dust-free and dirt-free clean room is produced in the interior of the packaging unit, which meets all the conditions that requires the protection or cleanliness requirements of the glass. Depending on requirements, an overpressure can be generated and maintained in the interior of the packaging unit in order to preclude ingress of ambient air.

In a further embodiment according to the invention, the packaging unit can be lined with air cushions. These may be, for example, pneumatic tires, air cushions, air cushions or foamed materials, which are filled or inserted in the interior of the packaging box between one or more wall parts and a glass roll. These may be provided additionally or alternatively to the shock and vibration damping measures described above. It is also possible to insert inflatable air cushions into the packaging unit and to inflate them only when the glass roll has been packed in the packaging unit. The pressure on the air cushion can be adjustable and controllable, but it must not be so high that the pressure of the variable volume on the glass roller to damage the same, especially in the edge region. In a further embodiment, the glass roll in the packaging unit can be enclosed by a double-walled hose. This can be filled after packing the glass roller with a gas, a liquid, or a solid, small-sized, compressible material, for example in flake, powder or spherical form. By metering the amount of filled material and its compressibility in the hose, an external adjustable force can act on the glass roll and its layers which prevents the layers of the glass roll from shifting against each other. On the other hand, the hose acts as a damping element and the compressibility of the filled material prevents shocks and vibrations acting on the glass roller from damaging it. Such a hose may be provided additionally or alternatively to the shock and vibration damping measures described above.

The invention further comprises the use of a described packaging unit for the vibration-reduced storage and the vibration-reduced transport of a rolled up on a winding core glass, in particular a thin glass. Here, the integrated damping elements act as vibration or vibration or shock absorbers in all possible spatial directions. They wholly or partially reduce or absorb the transmission of vibrations and shocks during handling, storage or transport of the packaging unit from outside to inside the glass roll such that the entry of shocks and vibration loads on or into the glass roll effectively reduces to an extent which allows safe transport or safe storage of a glass roller.

The invention further comprises the use of a described packaging unit as a dust-free and dirt-free clean room for the storage and transport of a rolled up on a winding core glass, in particular a thin glass. The packaging unit is gas-tight and sealed with this filled with a clean gas. As gas, depending on the requirement, all inert gases such as argon, nitrogen or carbon dioxide are preferred. The relative humidity is preferably set in a range of 5 - 30%. The packaging unit meets all the conditions required for the protection of the glass. This is particularly important, for example, in the case of coated thin glasses, when the coating is sensitive to substances which may be affected by environmental influences or also to glass substrates for displays, such as liquid crystal displays or organic LED displays, where due to their intended use, clean glass without dirt adherence and dust is required.

Fig. 1 and Fig. 4 show a rectangular packaging unit, Fig. 1 in cross-section, Fig. 4 in longitudinal section. The glass roll 30 shown in FIG. 4 is enclosed by the wall parts of the packaging unit, such as the head parts 121 and 123, the bottom part 13, the side parts 141 and 142 and the cover part 15. Here, all wall parts are firmly connected except for the head part 123, the head part 123 is removable for loading and unloading the glass roller. Alternatively, the wall parts can also be firmly connected or detachable with each other in a different combination, wall parts also being part of the detachable part and partly belonging to the firmly connected part of the packaging unit. For transporting or parking the packaging unit, it is loosely or firmly connected to a transport pallet 28 via the bottom part 13. For transporting with a lifting tool 15 grommets 16 are provided on the cover part. For receiving a glass roller, a holding element is connected to the head-side wall part, the head part 121 with the anchoring 122. The holding element is in this embodiment, a continuous support mandrel 181st The anchoring is designed such that the support mandrel 181 can absorb the glass roller 30 during horizontal loading over its entire length and support supported on one side. The anchoring 122 is non-positively connected, for example via screw connections with the head part 121 and possibly also with the cover part 15, the side parts 141, 142 and the bottom part 13 or also positively mounted in the packaging unit. To fix the glass roller 30 on the support mandrel 181, adjoining the anchors 122, 124 fixing rings 171, 172 are provided. They are made of a sturdy material such as wood, plastic or metal and offer the winding core with the possibly rolled up glass a secure hold against axial slippage during transport. You can also choose from a com- primable material which is suitable to clamp the winding core between the two fixing rings.

To close the packaging unit of the removable wall part or alternatively the removable wall parts is connected to the rest. This can be achieved by any known means such as e.g. Screwing, anchoring, bracing, hooking or locking be made. The removable head-side wall portion consists of the head portion 123 with the anchor 124 for the support member 182. The support member 182 is in this embodiment, a pin which engages in a matching recess at the end of the support mandrel 181 and supports the support mandrel 181 on this side, so that the Carrying mandrel is mounted on two sides in the closed packaging unit. At the anchor 124, a fixing ring 172 is further attached to fix the winding core 191. Alternatively, the fixing ring can also be pushed onto the circumference of the pin.

For loading, the glass roller 30 with the winding core 191 can also be introduced vertically into the packaging unit. In this case, the packaging unit is placed on the head part 121, loaded with the glass roller, closed with the head part 123, so that the winding core 191 is enclosed between the holding elements. Then, the packaging unit is rotated by 90 ° and stored on the bottom part 13. The advantage here is that the anchor 122 only has to be designed so stable that it must carry and support the glass roll as part of a two-sided storage. The packaging unit can thereby be made smaller and lighter.

2 and 3 alternatively show the cross section of two cylindrical packaging units, wherein the side parts 143, 144 are cylindrical and the head parts are each formed round. To support the packaging units support elements 293 and 294, 295, 296 are provided on the outside. The packaging Resting cung units, secured by the support elements, on a bottom plate 291, 292.

Fig. 5 shows a corresponding packaging unit to Fig. 4 with a damping element 20 on the outwardly facing bottom of the bottom part. This is a full-surface underlying vibration damping plate. Alternatively, two strips below the side parts 141, 142 are provided. The vibration damping plate is designed according to a fall protection mat made of rubber granulate. In this way it can be effectively prevented that shocks or vibrations, which act from below on the packaging unit, are inadmissibly transferred to the packaging unit and are transmitted via the latter into a glass roll to be transported.

Fig. 6 shows a corresponding packaging unit to Fig. 4 with damping elements, which are respectively arranged in the head-side wall parts and enclose the anchoring of the holding elements. The damping elements are rectangular in the shape of the interior of the anchorage. The anchor 125 is designed without cross braces and includes damping elements 201, 202 which enclose the extension of the support mandrel 181. In addition, vibration damping plates may also be provided between the anchor 125 and one or more wall portions 13, 15, 121, 141, 142.

On the removable head side of the wall, an annular damping element is arranged in the anchoring plate 125, which surrounds the holding element 182, here in the form of a pin. The damping element can also be rectangular. The damping element consists of a rubber-metal compound or alternatively also of a pure rubber compound. In this way, a vibration decoupling of the retaining element and a glass roller can be made wholly or at least partially and effectively prevented that bumps or vibrations, especially perpendicular or obliquely, but also those which act parallel to the axis of a holding element on the packaging unit, are transmitted via the holding element in a glass roll to be transported.

FIG. 7 shows a corresponding packaging unit to FIG. 4 with damping elements which respectively enclose the holding elements or the holding element. In the illustrated embodiment, the holding element is a continuous carrying mandrel 183. During loading, it is mounted on one side in the anchoring 122. In contrast, in the sealed packaging unit, the carrying mandrel 183 is mounted on two sides and is additionally held and supported by the holding element 184, a pin which engages in the end of the carrying mandrel 183. The holding element 184 is held in the anchoring 126, which with the head part 123 is part of the head-side wall element. In particular, at the points where each end of a winding core come to storage, the support mandrel 183, each with a damping element, such as the damping rings 204, 205 enclosed, which then act as a shock and / or vibration damper between the support mandrel and the winding core. However, other segments of the support mandrel with damping elements or also the entire support mandrel can be enclosed with a damping material. The damping material is a rubber-metal compound or alternatively also a pure rubber compound. In this way it can be effectively prevented that shocks or vibrations are transmitted via the holding element in a glass roll to be transported.

Alternatively it can be arranged on each head side of the packaging unit as a holding element in each case also a pin-shaped support mandrel which engages in the cavity of the winding core and this supports. The support pins are then completely or partially enclosed by a damping ring.

FIG. 8 shows a corresponding packaging unit to FIG. 4 with an air cushion 21 around a packed glass roll 30 in the lower region, and FIG. 9 shows a corresponding packaging unit to Fig. 4 with an air cushion 22 as a pneumatic tire around the entire circumference of a wrapped glass roll 30. The air cushion are each individually inflatable from the outside via a valve, not shown. For transport, the air cushions are filled with air and it is set a defined pressure, which is optionally adjustable and monitored. By adjusting and selecting the pressure in the interior of the air cushion 21, 22 and the consequent compressibility of the pad can be an adjustable force acting on the glass roller and its layers which prevents the layers of the glass roll move against each other. On the other hand, the air cushion acts as a damping element and the compressibility prevents shocks and vibrations, which act on the glass roller, can damage them. To unload the packaging unit, the air is drained or sucked off via the valve.

Fig. 10 shows a corresponding packaging unit to Fig. 5 as a clean room for a wrapped glass roll. The packaging unit is made gas-tight in this embodiment and sealed. After loading and closing the packaging unit, a negative pressure or a vacuum is sucked into the interior via a valve, not shown, and then the space is filled with a clean gas such as nitrogen or carbon dioxide, so that a clean room 23 is created. The relative humidity is set within a range of 5 - 15%. The pressure inside the packaging unit is adjustable and adjusted to be slightly above ambient pressure. As a result, in particular contaminated or moist ambient air is prevented from penetrating, as is especially necessary for problematic transport or storage conditions or corresponding risks or for sensitive, usually coated glasses. In the alternative, desiccants are provided in the packaging unit. Fig. 1 1 shows a unit of two packaging units, which have been assembled in a modular manner. For this purpose, a bottom plate 24 is arranged below the packaging unit, at the corners of each corner supports 25 are mounted, which can engage in stacking the packaging units in centering on the top of the packaging unit. Advantageously, they are each designed conically interlocking. In order to prevent swinging or vibration of the packaging units due to deflection, depending on the requirement, several means 26 are arranged on the bottom plate 24, which are supported on the bottom or on the cover part of a packaging unit. But there are also all other possibilities known to those skilled in a safe against slipping stacking conceivable.

It is also possible to provide devices which are not shown laterally on the packaging units and allow the packaging units to be connected to one another while standing side by side. Here are all known to the expert options for locking, mating, snagging oa. applicable. Overall, a solid composite packaging units to be created, which avoids a collision or hitting a common transport. In particular, dampening elements made of a rubber compound or cork are arranged on the contact surfaces of the packaging units or the supports themselves are designed as buffer elements made of a rubber-metal compound.

Fig. 12 shows the cross section of a support mandrel 185 with an attached winding core. At its upper periphery, the support mandrel has a recess to which two bearing surfaces 31 1, 312 connect to the winding core, whose diameter is adapted so that a maximum support of the winding core is made possible.

Alternatively, a support mandrel according to FIG. 13 may also be used, in which the bearing surfaces 313, 314 are adapted to the radius of the winding core are. In order to be able to easily load and unload the winding core with the rolled-up glass in the packaging unit, the cross section of the holding element 186, here a support mandrel, is kept small. The bearing surfaces 313, 314 are formed by damping elements 206, 207, which extend axially along the receiving surfaces 321, 322 of the support mandrel 186 for the winding core 193.

An advantage of this design is that a larger support surface can be provided for the winding core and the pressure or bending stress is reduced in the glass roller. By the damping elements, a transmission of shocks and vibrations can be reduced or decoupled.

Alternatively, all possible shapes for the cross section of a holding element are possible.

It is understood that the invention is not limited to a combination of the features described above, but that the skilled person will arbitrarily combine all the features of the invention, as far as is expedient.
