Description

Packaging unit for coiling the glass of the wound core

The present invention relates to a packaging unit for coiling a glass of a wound core and the use of such a packaging unit.

For example, in the field of consumer electronics (such as glass covers for semiconductor modules, organic LED light sources or thinner display devices) or in the field of renewable energy or renewable energy technologies (such as solar cells), the application of thin glass is becoming more and more extensive. For example, it can be applied to touch panels, capacitors, thin film batteries, flexible printed circuit boards, flexible OLEDs, flexible photovoltaic modules, or electronic paper. Thin glass has many outstanding characteristics, such as chemical resistance, temperature change resistance, heat resistance, air tightness, high insulation, suitable expansion coefficient, flexibility, high optical quality, high light transmission, and its flame The polished surface has a very low roughness and therefore has a high surface quality, so thin glass is increasingly favored in many fields. Thin glass herein refers to a glass plate, glass rail, glass substrate or glass film having a thickness of less than about 1.2 mm and above 15 μm and below 15 μm. Thin glass is more flexible and is typically rolled up and stored in the form of a glass roll after manufacture, or shipped for assembly or processing. The advantage of coiling glass compared to materials that store and transport planar extensions is to achieve compact storage, transportation, and processing operations in a more cost effective manner.

In order to further reduce transportation and storage costs, it is advantageous to coil as small as possible, but this will increase the tensile stress in the glass ribbon and increase the fracture. Danger.

As a friable material, the glass having the above-mentioned outstanding characteristics is less resistant to tensile stress, so that the breaking strength is low. In order to store and transport such glass rolls without damage, the quality and integrity of the edges must first be ensured to prevent cracking or breakage in the rolled glass ribbon. Even damage such as fine cracks (microcracks) may cause more cracks and even breakage of the glass ribbon. Secondly, after the glass ribbon is rolled up, its top surface is subjected to tensile stress, so it is necessary to ensure that the surface is intact and free from scratches, dents or other surface damage to prevent cracking or cracking in the rolled glass ribbon. Third, manufacturing-related internal stresses within the glass should be minimized or eliminated to prevent cracking or fracture in the rolled glass ribbon. There is always a limit to the material properties of the rolled glass, and in the industrial manufacturing process, all of the above three factors can only be optimized within a limited range, and the fracture resistance is further improved. Therefore, special measures and conditions are required to store and transport such glass rolls to prevent damage to the glass. In particular, the glass is protected from shock and vibration loads. Otherwise, such external loads may cause the glass to exceed the fracture limit and create cracks on the glass.

For example, when the glass is placed on a certain mounting surface (such as a pallet) in such a manner that its axis is substantially horizontal, there may be a problem of stress concentration in the contact area, and it is easy to cause breakage on the glass ribbon.

For thick glass, such as flat glass and conventional glass for flat screens, which is extremely difficult to bend, it is important to store, transport and operate the glass material extending in a plane. For such planarly extending glass materials For a package, see, for example, US 2007/0131574 or JP 048577/1990. However, this type of packaging is not compact and is completely unsuitable for packaging glass rolls.

WO 2008/123124 describes the wrapping of rolled material in a coil. In order to protect both sides of the coil from impact, the case is provided with a flat flange member with an additional tubular member on both sides, which are all engaged in the cavity of the winding core. The two tubular members are each formed by integrating a polyolefin-polystyrene foam for absorbing impact energy. In addition, an intermediate cavity for edge protection is disposed between the upper edge of the rolled material and each of the flanges. However, this type of packaging is not suitable for glass rolls because the surface of the glass roll has a large surface extension and cannot be protected between the flanges. Even if an intermediate cavity is provided and the corresponding coiled support material is selected, the glass will be subjected to accidental vibration. Energy and impact energy. In addition, the case did not provide a solution for reliable storage and transportation of large quantities of glass rolls.

JP 2009-173307 describes an improved solution for storing and transporting a sensitive measuring pressure bow (Druckmessbogen) coiled onto a winding core, which proposes a package form in which the winding of the wound core has the test Both ends of the compression bow are provided with flanges having a larger diameter than the wound mandrel. Thereby the pressure measuring bow is kept at a certain distance from the mounting surface. Unlike the pressure measuring bow, the glass film at this time is a material that is easily broken. That is to say, only the microcapsules for pressure measurement on the surface of the measuring bow should not be broken, but on the rolled glass, in addition to the surface of the coil, it is necessary to pay attention to the edge of the side belt of the glass ribbon. No breakage occurs. The two sides of the tape containing the edge of the glass ribbon may be exposed to the outside, so the two sides can easily become the starting point of the fracture phenomenon.

WO 2010/038760 describes a modification of the glass roll. In the case of a glass roll wound with a lateral flange of the winding core, the present invention describes various cushioning arrangements in which a corresponding cushioning material is placed between the side regions of the glass roll and the flange. Thereby the edges of the glass ribbon are prevented from coming into contact with the flange which would cause the edges to break.

To this end, the proposal proposes to coil a laterally projecting intermediate layer between the layers of glass ribbon which only partially fills the intermediate cavity and does not come into contact with the flange or, in another embodiment, contacts the flange. . However, in the process of rolling up or unrolling the glass roll, the glass ribbon may crack or break in the case where the protruding portion of the intermediate layer is caught or caught. In addition, the layer of glass ribbon on the coil may also be displaced laterally due to impact or vibration during transportation, which may also result in breakage of the ribbon or damage to the edges. Wherein, the lateral displacement of the glass ribbon may refer to an overall displacement along the axial direction of the glass ribbon winding core, or the outer diameter side of the glass ribbon may be laterally moved on the opposite side of the coil and the edge of the glass ribbon Stepped stacking (lateral "stretching") occurs.

According to another embodiment, a separate cushioning material is disposed between the glass roll and the flange. Although this can reduce the lateral displacement of the glass ribbon on the coil due to impact or vibration during transportation, the edge of the glass ribbon and the cushioning material will be relatively moved due to transportation-related vibration. Even in the case where the relative motion is extremely slight or the relative motion causes the stress on the edge of the glass ribbon to be extremely small, the edges may be damaged or cracks may be generated in the glass ribbon.

In order to prevent the above phenomenon from occurring, another embodiment proposes that the buffer material is only Contact with the flange without touching the side area of the glass roll. However, the glass ribbon layer may also cause overall lateral displacement or lateral expansion and contraction on the coil due to impact or vibration during transportation, and may result in breakage of the glass ribbon or damage to the edge.

WO 2010/038760 also proposes a shaft component embodiment which laterally projects beyond the flange and is supported by bearings arranged in the base. This eliminates the need for a flange to prevent the glass roll from rolling. A package can also be utilized to cover one or more of such structures. However, the disadvantage of this solution is that the impact and vibration loads are transmitted unimpeded to the glass roll, thereby increasing the risk of glass breakage and cracking. In addition to packaging with transverse glass rolls, the case also proposed packaging with vertical glass sheets. Wherein, the winding cores of the plurality of glass rolls are placed on the corresponding vertical cylindrical elements, and the cylindrical elements are fixed to the bottom of the box. However, the disadvantage of this solution is that the glass roll will sway during transportation. Even if the glass ribbon is broken to prevent such swaying and the glass rolls are kept at a sufficient distance or the cushioning material is filled between the glass rolls, the edge on the surface of the glass roll is also subjected to the pressure of the glass roll. The unexpected effect of the roll sloshing, which causes the glass ribbon to crack and break and the edge is damaged. In addition, the impact and vibration loads here are also transmitted unimpeded to the glass roll, thereby increasing the risk of glass cracking and cracking.

In view of the above, an object of the present invention is to eliminate the aforementioned drawbacks and to provide a packaging unit for carrying a glass wound on a winding core, which can be lowered Low risk of breakage and cracking of the glass during storage or transportation. Another object of the invention is to find a solution for reliably packaging a plurality of glass rolls.

The solution to achieve the above object of the present invention is the feature of claim 1 and the scope of claims 12 and 13.

The glass roll is integrated into a closed packaging unit to protect the glass roll from direct physical or chemical effects or effects from the outside. Such a packaging unit consists of at least two wall parts which can be separated from each other, wherein the wall parts are combined together as a closed unit. Distinguishing the wall members of the packaging unit by: two head members of the packaging unit disposed opposite the side regions of the glass roll, and wall members of the packaging unit surrounding the width direction of the glass roll, such as Bottom part, side part and top part. The packaging unit can be rectangular, polygonal or cylindrical.

When the packaging is carried out, for example, all the wall members of the packaging unit can be assembled as a single component, or the wall components can be assembled in any form of a fixedly connected component group.

According to a preferred embodiment, the side members, the bottom member and the top member or the cylindrical wall member are coupled to a head member, and therefore, in the process of packaging the glass roll to form a packaging unit, only It is only necessary to connect the other head part to other parts. The side members, the bottom member, and the top member may also be connected to each of the head members by half the length.

In the case of a cylindrical embodiment, the bottom member, the side members and the top member form a hollow cylinder, wherein the hollow cylinder separately forms a wall And assembling the component with the two head components, or the hollow cylinder has previously been attached to a head component and assembled with the second head component, or the hollow cylinder can be connected as a component to the two head components, wherein A closed packaging unit is always produced when the assembly is implemented.

The material of the wall members may be any material having sufficient stability such as wood, plywood, metal or plastic. When selecting materials, take into account the corresponding air tightness or environmental resistance according to the specific requirements of transportation or storage.

According to the invention, the wall members constituting the head members are each connected to a holding member. The retaining elements are disposed opposite each other and, when in use, support the glass roll or the winding core between the retaining elements such that the glass roll can be used to form the bottom member, the side members, and the wall of the top member The components are carried in the packaging unit at a distance.

The retaining element can be attached directly to or anchored to the wall member or to the wall member. An anchoring structure can also be assigned to the wall member. At this point, the anchoring structure can be fixedly attached to the wall member or only in loose contact therewith. By way of example, the anchoring structure can be positioned as a separate component in front of the head component and connected to the head component and/or to the adjacent wall component in a form-fit or press fit. Regardless of the embodiment, the anchoring structure is fixedly coupled to the packaging unit in the closed state of the packaging unit.

The anchoring structure may be formed by two sheets spaced apart from each other, which may be supported by one another as needed to form a supportable anchoring structure for a retaining element, the retaining element not requiring the second retaining element Can roll into the glass Row bearing and support. The anchoring structure, for example, can also be mounted as a reinforcing plate on the inside of a head member and carrying the retaining element.

Such a retaining element may, for example, comprise a pin, a spindle, a pin, a latch or a seal which can be inserted into a respective connecting device on one end of the mandrel, wherein the two retaining elements can be wound with a glass winding core of the case. The body is reliably carried between the two holding elements.

According to a preferred embodiment, a retaining element is embodied as a cavity that can be embedded in the winding core or embedded in a corresponding groove, the cavity or the groove being arranged at the side end of the winding core. The embedded portion of the retaining element (eg, the mandrel, one or more pins or pins) can have any cross section.

The winding core can be circular or polygonal. The winding core can, for example, consist essentially of a tube such that the retaining elements are inserted into the side ends of the tube. The retaining elements can have tapered regions for centering the wound core.

The two ends of the winding core may also have one or more grooves of a particular shape so that suitable objects on the retaining elements are embedded therein and preferably center the winding core. The grooves may for example also be conical, frustoconical, pyramidal, truncated, or any other corresponding shape. One or both ends of the winding core may also be provided with attachment means that are anchored to corresponding objects on the retaining element such that the side ends of the winding core are connected to the retaining element. Such a device can be implemented, for example, as a bayonet connection or as a device for snapping in, snapping, latching or tightening.

According to a preferred embodiment, a generally tubular winding core is provided a continuation support mandrel extending along a cavity axially distributed within the winding core, the winding core generally abutting the support mandrel over its entire internal length and on the support mandrel Supported. According to an embodiment, the support spindle is fixedly connected to a retaining element and attached to the retaining element, the support spindle being connected or anchored to the second retaining element in the assembled state of the packaging unit. In the assembled state of the packaging unit, the support mandrel can also be attached or anchored as a separate component to each of the retaining elements. Such a connection or anchoring can be achieved, for example, by insertion, tightening or any suitable means.

In the simplest case, the support mandrel may have a circular cross section, wherein when the support mandrel diameter is smaller than the inner diameter of the winding core, the crucible forms a single axial extension for the winding core. Support surface. When other cross-sectional shapes are selected, two or more axially extending support faces can also be produced, whereby the support effect on the winding core can be improved. In the above manner, it is possible to effectively prevent or reduce the bending of the glass roll in storage or transportation for a long time in the event of impact or vibration.

According to another embodiment, a support mandrel can also be fixed or anchored to each of the retaining elements, or a support mandrel can be fixed or anchored to each of the retaining elements in the assembled state of the package unit. For carrying or supporting a wound core or a roll of glass with a wound core, the two support mandrels are embedded in respective side ends of the wound core when in use. A degree of embedding can be achieved such that the two support mandrels are in near contact, or the two support mandrels only enter the respective side end regions of the winding core.

According to a further embodiment, the continuous support mandrel or the component of the support mandrel holding element, or the portion of the retaining element embedded in the winding core, is embodied as being tensioned in the winding core. This is done by using the largest bearing surface to prevent the bending from occurring even under extreme load. In addition, the glass roll does not vibrate on the support (such as the support mandrel), so that reliable transportation is maximized.

According to a further refinement of the invention, at least one retaining element and/or at least one wall component is connected to the damping element. The damping element dampens oscillations, vibrations or shocks in all spatial directions. The function of the damping element is to attenuate or completely absorb the vibrations and shocks transmitted from the outside to the inside of the glass roll during operation, storage or transport of the packaging unit. Thereby, the impact or vibration load acting on the glass roll can be effectively reduced to transport and store the glass roll in a reliable manner.

There are many ways to create an impact, such as vehicle transportation, improper handling of the packaging unit, or any form of impulse, which refers to the pulse load that is allowed to be transmitted to the glass roll in a manner that does not present a hazard to the packaging unit.

The vibration load is characterized by frequency dependence. The vibration load includes periodic loads, such as short-frequency vibrations in the frequency range of 0.1 Hz to 20 kHz, especially 50 Hz to 10 kHz. Such vibrations may be generated during transportation by shaking or motor vibration and transmitted to the transport. Glass rolls and caused losses.

In addition, other loads acting on the glass roll, such as centrifugal force, acceleration force or braking force, may occur during transportation.

The packaging unit of the present invention has one or more damping elements, and the damping elements Shock or vibration is mitigated and the transfer to the glass roll is mitigated for reliable transport and reliable storage of the glass roll. The damping element is coupled to at least one retaining element, at least one wall member or to an anchoring structure assigned to a wall member. The various embodiments can be combined in any manner with the aim of providing overall optimum protection for the glass rolls to be transported in accordance with all expected loads.

According to an embodiment, at least one wall member is provided with a damping element that surrounds or surrounds the anchoring element in a region of the wall member, wherein the anchoring structure is the head Part of the part. Thereby, it is possible to effectively prevent an impact or vibration, which acts in particular in a direction perpendicular or inclined to the axis of the holding element, from being transmitted to the glass roll to be transported via the holding element. Furthermore, it is also possible to reduce the shock or vibration acting in a direction parallel to the axis of the holding element.

According to a further refinement of the invention, at least one of the retaining elements can be embodied as an outer surface of the pin or pin support spindle which can be provided with one or more at least partially and at least partially enclosed damping elements, which are In use, it is connected to the holding element in a manner that dampens the winding core. For example, the damping elements can be one or more elastic damping rings spaced apart from one another. It can also be implemented as one or more axially extending damping elements. Thereby, it is possible to effectively prevent the impact or vibration acting on the packaging unit from being transmitted to the glass roll to be transported via the holding unit.

According to another embodiment of the invention, the continuous branch through the winding core At least one outer surface of the mandrel may be provided with one or more at least partially and at least partially enclosed damping elements. The damping elements can be arranged, for example, only at the side ends of the winding core or over the entire length of the winding core. For example, the damping elements can be one or more elastic damping rings. The entire surface of the support mandrel may also coat or surround a certain damping material. The support mandrel can also be constructed entirely of a damping material. In this way, the quality of the wound core of the coiled glass can be carried on the support mandrel or the holding elements in a vibration-damping and impact-resistant manner during use. The crucible can effectively prevent the impact or vibration acting on the packaging unit from being transmitted to the glass roll to be transported via the holding unit or the supporting mandrel.

According to a further embodiment of the invention, the support mandrel is carried in the retaining element in an elastic or damping manner. The damping element in this embodiment constitutes a support for the support mandrel in the retaining element, wherein the support mandrel can be a continuous or discontinuous support mandrel or, in this embodiment, one or more pins Or pin.

According to one design, for example, a damping arrangement can be used such that the support mandrel, pin or pin is suspended from the true main bearing, suspended on the two springs and supported by the two impactors. In this way, the support mandrel, pin or pin can vibrate, but will be slightly braked by the impactor when the deviation is too large.

According to a further refinement of the invention, the outer side of the packaging unit, preferably below the bottom part, can be provided with one or more damping elements. For example, if A damping element is mounted on the outside of the bottom part, and the damping element constitutes, for example, a placement surface of the packaging unit placed on the pallet. A plurality of planarly distributed or point-distributed damping elements may also be mounted on the outer side of the bottom member, such as cushioning elements or impactors in the respective corner regions, or strips on the side regions of the two opposite sides. Furthermore, the entire bottom area can also be composed of a layer of damping material. Such a damper plate may be constructed of cork, rubber, rubber metal connectors or preferred materials. It is preferable to use a vibration damping pad or a vibration damping plate. Thereby, it is possible to effectively prevent the impact or vibration from acting on the packaging unit from being unauthorisedly transmitted to the packaging unit and transmitted to the glass roll to be transported via the packaging unit.

In order to resist lateral impact, top-down impact or prevent vibration transmission in the assembled state of a plurality of packaging units, a damping element may be provided at any position outside the packaging unit that achieves the corresponding purpose. The damping elements may cover the entire outer surface of a wall member or only cover most or a small portion thereof.

According to another embodiment of the present invention, the packaging unit of the present invention may be laminated or combined in a certain manner into a larger packaging unit, so that the outer side is in contact with each packaging unit ( Preferably, one or more damping elements are provided on the placement surface above or below the packaging unit or on the lateral contact surface of the packaging unit.

The damping elements are, for example, cushioning elements or impactors consisting of elastomers (such as rubber, polyxylene, raw rubber or foaming materials) or elastic springs (especially metal knits). It is also possible to use, for example, a damping element comprising a metal knit or a gas damping element. The invention can be used by those skilled in the relevant art. All damping elements are well known. The appropriate deformation path and vibration reduction can be selected by selecting the appropriate shape and/or material, depending on the task. The quality of the glass roll or packaging unit to be elastically treated or damped is taken into account when determining the dimensions and associated parameters for the damping elements. According to one embodiment, the damping element herein refers to a gas pressure damping element that adjusts the damping through an adjustable air pressure applied to the mass of the glass roll to be packaged.

In either case, the above elements can also suppress or prevent the mass to be packaged from vibrating at a natural frequency.

According to another embodiment of the present invention, in order to package a plurality of packaging units, at least two packaging units may be stacked one on top of the other and/or side by side, and assembled in a modular manner. For this purpose, the placement surface and the top surface of the lower part of the packaging unit and/or the lateral direction are provided with a carrier device for the interaction of the other packaging unit. The carrying devices can cooperate in a form-fitting manner, for example, a packaging unit is provided with a recess, and a projection of the other packaging unit is embedded in the recess. The packaging units can also be combined in a tight fit manner, wherein the two packaging units can be fixedly locked together by the carrying device, or the two packaging units can be fixedly connected together by any means.

According to an embodiment of the invention, the bearing surface of the carrier device that is in contact with the two packaging units is provided with a damping element.

According to a further refinement of the invention, the packaging unit is hermetically sealed and filled with a clean gas inside. Thereby, a dust-free and dirt-free clean room can be produced inside the packaging unit, and the clean room meets the protection or clean requirements of the glass. All the conditions you need to have. A negative pressure may also be formed in the interior of the packaging unit as needed to prevent ambient air from entering.

According to another embodiment of the invention, the packaging unit may be provided with a corresponding air cushion. For example, it may be a pneumatic tire, an air bag, an air cushion, or a foaming material between one or more wall members and a glass roll that is filled or placed in the inner cavity of the package. These air cushions may be considered as a supplement or alternative to the aforementioned anti-shock and vibration damping measures. The inflatable airbag may also be placed in the packaging unit and inflated under the condition that the glass unit is wrapped in the packaging unit. The pressure applied to the bladder can be an adjustable and controllable pressure, but the pressure must not be such that the pressure exerted by the variable volume solid on the glass roll is sufficient to cause the glass roll (especially its edge region) Damaged.

According to another embodiment, the glass roll can be surrounded by a double wall hose in the packaging unit. The hose may be filled with a gas, liquid or some compressible solid particulate material after packaging of the glass roll, which is, for example, in the form of a floc, a powder or a sphere. The filling material is quantitatively distributed, and the filling material is compressible in the hose, so that an external adjustable force can be applied to the glass roll and its position, and the force prevents the position of the glass roll. Relative displacement occurs. In addition, the hose also functions as a damping element whose compressibility prevents damage or vibration of the glass roll from damaging the glass roll. Such a hose may be considered as a supplement or alternative to the aforementioned shock and vibration mitigation measures.

The invention also includes an application of the aforementioned packaging unit for vibration-damping storage and vibration-damping transportation of glass, particularly thin glass, wound on a winding core. its These integrated damping elements are used as dampers, anti-oscillators or impactors for all spatial directions. The damping elements attenuate or completely (or partially) absorb the vibration and impact transmitted from the outside to the inside of the glass roll during operation, storage or transportation of the packaging unit, thereby effectively reducing the impact or vibration load acting on the glass roll, so as to Transport and store glass rolls in a reliable manner.

The invention also includes the use of the aforementioned packaging unit for storing and transporting a dust-free and dirt-free clean room for coiling a glass, particularly a thin glass, of a wound core. To this end, the packaging unit is hermetically sealed and filled with clean gas. The gas is preferably any inert gas such as argon, nitrogen or carbon dioxide, depending on the specific requirements. The relative air humidity is preferably 5-30%. The packaging unit meets all conditions for glass protection. This is of particular importance in coated thin glass and glass substrates for displays such as liquid crystal displays or organic LED displays, where the coating on the thin glass reacts sensitively to substances that may be affected by environmental factors, while the display There is a high demand for the cleanliness of the glass, that is, the absence of dirt and dust.

The invention will now be described in detail by means of exemplary drawings.

The glass roll 30 shown in Fig. 4 is surrounded by the wall members of the packaging unit (e.g., the head members 121 and 123, the bottom member 13, the side members 141 and 142, and the top member 15). Wherein all the wall members except the head member 123 are fixedly connected, and the head member 123 is removable. Plan to load or remove the glass roll. Alternatively, the wall members may be fixedly attached or removable in other combinations, wherein the wall members may be of a separable solution, some of which may be removable components of the packaging unit, and some of which are fixed attachment members of the packaging unit. When the packaging unit is transported or stored, the packaging unit is loosely connected or fixedly connected to the transport pallet 28 by its bottom part 13. A retaining ring 16 is provided on the top member 15 for transport using a lifting tool. The head side wall member (head member 121) is provided with a retaining member that connects the anchoring structure 122 to carry the glass roll. The retaining element is a continuous support mandrel 181 in this embodiment. The anchoring structure is designed such that the support mandrel 181 can accommodate the entire length of the glass roll during horizontal loading of the glass roll 30 and can be supported on one side. The anchoring structure 122 is press-fitted, for example, by tightening the screw with the head member 121 (and optionally with the top member 15, the side members 141, 142, and the bottom member 13), or is mounted to the package in a form fit manner. In the unit. To secure the glass roll 30 in the support mandrel 181, retaining rings 171, 172 are provided adjacent the anchoring structures 122, 124. The retaining rings are made of a stable material such as wood, plastic or metal that securely holds the coiled core of the coiled glass to prevent axial slippage during transport. The retaining rings may also be constructed of a compressible material for clamping the winding core between the two retaining rings.

When the packaging unit is closed, the removable lower wall member or alternatively the removable lower wall member is coupled to the other wall member. This can be done with all known measures, such as tightening screws, anchoring, tightening, jamming or latching. This can be taken off The wall member on the head side is constituted by a head member 123 and includes an anchoring structure 124 for holding the member 182. The retaining element 182, in this embodiment, is embedded in a pin of a corresponding recess on the end of the support mandrel 181, the pin supporting the side of the support mandrel 181 such that the support mandrel is in the package unit It is supported on both sides in the closed state. A fixing ring 172 for fixing the winding core 191 is also fixed to the anchoring structure 124. Alternatively, the retaining ring can be pushed onto the periphery of the pin.

When loading is performed, the glass roll 30 can also be vertically inserted into the packaging unit together with the winding core 191. At this time, the packaging unit is placed on the head member 121, the glass roll is loaded, and the packaging unit is closed by the head member 123 so that the winding core 191 is inserted between the holding members. The packaging unit is then rotated 90° and carried on the bottom part 13. Wherein, the anchoring structure 122 preferably only needs to reach a certain degree of stability, so that it is sufficient to carry and support the glass roll as part of the double-sided load-bearing structure. Therefore, the packaging unit can adopt a smaller and lighter embodiment.

As an alternative, Figures 2 and 3 are cross-sectional views of two cylindrical packaging units in which the side members 143, 144 are all cylindrical and the head members are circular. Supporting elements 293 and 294, 295, 296 for supporting the packaging units are respectively provided on the outside of the packaging units. The packaging units are reliably supported by the support units on the bottom plates 291, 292.

The damping element is a full face The damping plate below. Alternatively, two straps may be provided below the side members 141, 142. The damper plate is implemented as a fall protection pad composed of rubber particles. Thereby, it is possible to effectively prevent the impact or vibration load from acting on the packaging unit from being unauthorisedly transmitted to the packaging unit and transmitted to the glass roll to be transported via the packaging unit.

Figure 6 is a schematic illustration of a packaging unit corresponding to Figure 4, comprising a plurality of damping elements, all of which are disposed in the wall member on the head side and enclose the anchoring structure of the respective retaining element. The damping elements are rectangular in the inner cavity profile of the anchoring structure.

Furthermore, a respective damping plate can also be provided between the anchoring structure 125 and the one or more wall members 13, 15, 121, 141, 142. An annular damping element is provided in the anchoring plate 125 on the removable lower head side of the wall, which surrounds the retaining element 182 embodied here as a pin. The damping element here can also be rectangular. The damping element consists of a rubber-metal connection or, instead of a pure rubber connection. In this way, the holding element can be completely or at least partially damped to the glass roll, and can be effectively prevented from acting in a direction perpendicular to or oblique to the axis of the holding element and also in a direction parallel to the axis. The impact or vibration of the packaging unit is transmitted via the holding element to the glass roll to be transported.

Figure 7 is a schematic illustration of a packaging unit corresponding to Figure 4, including a plurality of damping elements surrounding the holding elements or the retaining elements. The retaining element in this embodiment is a continuous support mandrel 183. The support mandrel is single when loading is implemented The side is carried in the anchoring structure 122. In the closed state of the packaging unit, the support mandrel 183 is supported on both sides, i.e., the support mandrel is held and supported by the retaining member 184 (the pin embedded in the end of the support mandrel 183). The retaining element 184 is retained in the anchoring structure 126, which is part of the wall element on the head side. The position of the support mandrel 183, in particular the need to carry the respective ends of the winding core, is respectively surrounded by a damping element (such as damping rings 204, 205) which resists between the supporting mandrel and the winding core. The role of the impactor and / or shock absorber. It is also possible to surround the other sections of the support mandrel with a damping element or to surround the entire support mandrel with a damping material.
