Description

Technical field

[0001] The following embodiments relate to a storage container for receiving goods to be transported, in particular powdery bulk goods and / or liquids, with the aid of which cost-effective and sustainable storage and transportation of goods is made possible. Furthermore, the following embodiments relate to a transport device with the storage container for receiving goods to be transported.Technical background

[0002] It is known that disposable big bags are used for the storage and transportation of bulk goods, which have to be cut open after a single use and then disposed of. These have a small capacity and cannot usually be stacked on top of each other, which makes transportation difficult. Emptying disposable BigBags is difficult because they do not have a defined outlet opening.

[0003] There is a need to make the storage and transportation of goods, in particular bulk goods and / or liquids, sustainable, cost-effective and easy to handle.

[0004] Based on this situation, the task at hand is to propose a storage container that is sustainable, cost-effective and easy to handle.Description - Technical solution

[0005] The present object is solved by the features of the independent claim. Advantageous embodiments are defined in the subclaims, the description and the drawings. If technically possible, the teachings of the subclaims can be combined with the lessons of the main and subclaims at will.

[0006] In particular, the objective is solved by a storage container for storing goods to be transported, in particular powdery bulk material and / or liquids, comprising: an elastically deformable wall; an inlet opening arranged on the wall for letting in the goods to be transported; an outlet opening arranged on the wall for discharging the goods to be transported; a plurality of elastically deformable belt elements arranged on the wall and extending at least partially along the outer surface of the wall; wherein the storage container is designed to perform a self-discharge through the elastic wall and the elastic belt elements.

[0007] In particular, the inlet opening and the outlet opening are shaped so that they can be closed. During the loading process, the inlet opening is open and the outlet opening is closed. This allows the storage container to hold the goods to be transported, wherein the capacity increases due to the elastic deformation of the wall. Due to the expansion of the wall, the belt elements arranged on the wall are also elastically tensioned. The pre-stressed wall and the belt elements, which are also under tension, allow the storage container to self-discharge during the unloading process. The outlet opening is opened first so that the goods to be transported can exit the storage container vertically through the outlet opening. The belt elements and the wall continue to contract, causing the remaining goods to be transported to be forced in the direction of the perpendicular bisector of the storage container. In the area of the perpendicular bisector, the goods to be transported can then sink vertically in the direction of the outlet opening and exit the storage container.

[0008] The storage container is an environmentally friendly solution for handling goods, in particular for the storage and transportation of powdery goods and / or liquids. Advantageously, this provides a sustainable, cost-efficient and environmentally friendly alternative to disposable containers and terminal-based solutions. Sustainability is achieved in particular by the reusability of the storage containers, which are largely recyclable, and by the reduction of waste and dust emissions. The storage container can advantageously be used flexibly in combination with a frame construction as a transport device by being compatible with the existing infrastructure, for example with cranes, forklifts, container stackers. In particular, the storage container is shaped to be weather-resistant, which improves the storage and transportation of the goods to be transported. Preferably, the storage container has a temperature resistance in the range of -30°C to 70°C, in particular according to DIN EN 1876-1 or N-Q-PA-1057. The dimensions of the transport device also allow several transport devices to be stored vertically on top of each other and transported through trucks, trains, ships and / or inside containers. The storage container, in particular the transport device, meets both the ecological and economic requirements of the logistics industry by improving the sustainability and efficiency of storage and transport.

[0009] In the following, advantageous aspects and further preferred modified embodiments are described and explained. Explanations, in particular regarding advantages and definitions of features, are by their nature descriptive and preferential, but not limiting examples. If an explanation is limiting, this is expressly mentioned.

[0010] Insofar as ordinal numbers, e.g. "first", "second", etc., are used, for example to designate a component, an element, a process step or a process operation, these ordinal numbers are intended solely for the purpose differentiation in the designation and do not indicate any dependencies or sequences. This means in particular that, for example, a device does not necessarily need to have a "first component" in order to have a "second component". Also, a device can have a "first component" as well as a "third component", without necessarily having a "second component". There can also be several units of the same ordinal number, including, for example, several "first components".

[0011] In particular, at least two belt elements are arranged intersecting along the wall. The intersecting belt elements allow the wall of the storage container to be acted upon more evenly in the direction of the perpendicular bisector of the storage container through the force stored by the belt elements.

[0012] Alternatively or additionally, it may be envisaged that the wall and the plurality of belt elements are designed to deform elastically during the filling of the storage container and to act directly and / or indirectly on the goods to be transported received with a force acting substantially in the direction of the perpendicular bisector of the storage container. In particular, a tensile force is generated in the plurality of belt elements when the storage container is filled, as a result of which the plurality of belt elements counteract elastic deformation of the wall during filling. In particular, the belt elements act on the wall orthogonally at the contact surfaces. In addition, the tensile force in the belt elements causes the wall to be acted upon at least partially in a vertical direction and at least partially in a horizontal direction. This causes the wall to contract during the unloading process. In particular, the wall contracts in the first area. As a result, the second area of the wall is also stretched in a vertical direction. As a result, a vertical passage can be formed up to the outlet opening, through which the goods to be transported can sink through gravity inside the storage container and exit at the outlet opening.

[0013] Alternatively or additionally, it may be envisaged that the storage container is designed in such a way that it has a service life of at least 30 cycles, in particular at least 40 cycles, preferably at least 50 cycles, wherein a cycle comprises the filling, transportation and discharging of the storage container. The long service life is favored in particular by a suitable choice of material for the wall. Due to the long service life, the storage container can be reused. This makes the storage container a sustainable, cost-efficient and environmentally friendly alternative to disposable containers. Sustainability is achieved in particular through the reusability of the storage container, which is largely recyclable, and through the reduction of waste and dust emissions.

[0014] Alternatively or additionally, it may be envisaged that the wall has a first area and a second area adjoining below the first area. In particular, the belt elements are arranged substantially in the first area of the wall. In particular, the storage container is shaped conically in the second area. In particular, the second area of the wall extends from the first area of the wall to the outlet opening. In particular, the outlet opening is arranged coaxially with the perpendicular bisector of the storage container. In particular, the inlet opening is arranged coaxially with the perpendicular bisector of the storage container. During the unloading process, the wall in the first area can thus be twisted at least partially vertically upwards and at least partially in a horizontal direction by the belt elements. The second area forms an essentially vertical passage. In the discharging state, the wall of the storage container is shaped like a funnel or has a Y-shape. This enables an essentially complete self-discharge of the storage container.

[0015] Alternatively or additionally, it may be envisaged that the storage container has at least one additional, elastically deformable belt element at least partially enclosing the wall on the peripheral side in the horizontal direction. In particular, the additional belt element is arranged essentially in the transition area between the first area of the wall and the second area of the wall. In particular, the additional belt element is arranged coaxially to the perpendicular bisector of the storage container on the wall. By means of the at least one additional belt element, the wall of the storage container can be compressed over the outlet opening during discharging of the storage container in such a way that the wall forms a passage running essentially vertically from the outlet opening to the first area of the wall. The passage is comparable to a downpipe. This ensures that the goods to be transported can escape completely from the storage container during discharging.

[0016] Alternatively or additionally, it may be envisaged at least one belt element, in particular all belt elements, has / have at least one, in particular at least two, guiding elements arranged on the wall for guiding the at least one belt element along the wall. In particular, the at least one additional belt element has at least four, in particular at least six, preferably at least eight guiding elements arranged on the wall for guiding the at least one additional belt element along the wall. The guiding elements ensure that the forces acting on the wall through the belt elements are distributed essentially evenly along the wall. As a result, the goods to be transported can be loaded essentially evenly in the direction of the perpendicular bisector of the storage container. This favors the realization of a self-discharge.

[0017] Alternatively or additionally, it may be envisaged the plurality of belt elements have a first end and a second end. In particular, the plurality of belt elements are each attached by the first end in an upper section of the first area of the wall. In particular, the plurality of belt elements are each attached by the second end in a lower section of the first area of the wall. In particular, the plurality of belt elements extend diagonally along the wall from the upper section to the lower section. In particular, the plurality of belt elements extend diagonally along the wall from the lower section to the upper section of the first area. In particular, one belt element crosses at least one further belt element, in particular at least two further belt elements, preferably three further belt elements, at respectively different positions on the wall.

[0018] Alternatively or additionally, it may be envisaged that the storage container has at least eight belt elements. In particular, four belt elements extend around the perpendicular bisector of the storage container in a clockwise direction from above to below along the wall. In particular, four belt elements extend around the perpendicular bisector of the storage container in an anticlockwise direction from above to below along the wall. The different directions of pull refer to a view of the storage container from above. The different directions of pull allow the belt elements to cross each other along the wall. This ensures that the wall is loaded both in the direction of the perpendicular bisector of the storage container and at least partially in a vertical and horizontal direction by the tensile force stored in the belt elements. In this way, the first area of the wall can be partially twisted and pulled vertically upwards. This ensures that the goods to be transported are pushed in the direction of the perpendicular bisector of the storage container during the final unloading process and can be discharged vertically through the second area of the wall through the outlet opening. This favors the self-discharge of the storage container.

[0019] Alternatively or additionally, it may be envisaged that the wall is at least partially made of polyester (PES). In particular, it is intended that the wall has a coating of polyvinyl chloride (PVC). In particular, it is provided that the wall has a coating of lacquer. The material composition favors a high reusability of the storage container. In particular, the composition and the coating allow fine powders and / or liquids to be picked up and transported. The coating also protects the storage container from external damage. As a result, the walls are shaped to be very flexible and expandable, which means that the capacity can be increased while the storage container is being loaded. A high modulus of elasticity also favors the realization of self-discharge of the storage container. In particular, the carrier fabric of the wall is made of 100% polyester, especially in accordance with DIN EN ISO 2076.

[0020] Alternatively or additionally, it may be envisaged that the wall has a weight per unit area of at least 1000 grams per square meter, in particular at least 1200 grams per square meter. In particular, it is intended that the wall has a weight per unit area of at most 1800 grams per square meter, in particular at most 1600 grams per square meter. The weight per unit area can be determined in particular according to DIN EN ISO 2286-2. The low weight per unit area favors the handling of the storage container. In particular, additional weight can be saved as a result.

[0021] Alternatively or additionally, it may be envisaged that the wall has a maximum tensile force in the warp direction of at least 7200 N / 5 cm. In particular, it is intended that the wall has a maximum tensile force in the weft direction of at least 6200 N / 5 cm. In particular, it is provided that the wall has a maximum tensile force in the warp direction of at most 7600 N / 5 cm. In particular, it is intended that the wall has a maximum tensile force in the weft direction of at most 6600 N / 5 cm. In particular, the maximum tensile force can be determined in accordance with DIN EN ISO 1421-1.

[0022] The maximum tensile strength of textiles describes the maximum load that a fabric can withstand in the warp or weft direction before it tears. The warp (also called warp threads) runs in the lengthwise direction of a fabric. The maximum tensile force in the warp direction therefore indicates how much load the fabric can withstand in this direction before the warp threads tear. The weft runs across the warp, i.e. in the width direction of the fabric. Accordingly, the maximum tensile force in the weft direction describes the maximum load that the fabric can withstand in this direction.

[0023] Alternatively or additionally, it may be envisaged that the wall has a tear propagation force in the warp direction of at least 1000 N. In particular, it is intended that the wall has a tear propagation force in the weft direction of at least 800 N. In particular, it is provided that the wall has a tear propagation force in the warp direction of at most 1400 N. In particular, it is intended that the wall has a maximum tear propagation force in the weft direction of 1200 N. In particular, the tear propagation force can be determined in accordance with DIN EN 17679.

[0024] The tear propagation force describes the force required to further enlarge an existing tear in a fabric. It is measured separately for the warp and the weft and is a measure of the resistance of the material to the propagation of tears. Tear propagation force in the warp measures the force required to further tear an existing tear along the warp threads (longitudinal direction of the fabric). It depends heavily on the strength and density of the warp threads. Tear propagation force in the weft describes the force required to propagate an existing tear along the weft threads (transverse direction of the fabric). The nature of the weft yarns also plays a decisive role here. The tear propagation force is particularly important for applications in which the material is exposed to mechanical loads or sharp edges. It is often determined using standardized test methods such as the Elmendorf method or the tensile test method.

[0025] Alternatively or additionally, it may be envisaged that at least one belt element, preferably all belt elements, is / are at least partially made of polyester (PES).

[0026] In particular, it is provided that at least one belt element, preferably all belt elements, is / are at least partially made of natural rubber (NR). This also applies to the at least one additional belt element.

[0027] Alternatively or additionally, it may be envisaged that at least one belt element, preferably all belt elements, has / have at least one outer material and at least one inner material. In particular, it is provided that the inner material is made of polyester (PES). In particular, it is provided that the outer material consists of natural rubber (NR). This also applies to the at least one additional belt element. The combination of several materials enables a robust belt element with very good stretch properties for use on the wall of the storage container.

[0028] PES is generally very tear-resistant and hard-wearing, both in dry and wet conditions. It is also resistant to UV rays and moisture, making it particularly suitable for outdoor applications. It also has high dimensional stability, even under the influence of temperature. Due to its insensitivity to many chemicals, oils and solvents, it is well suited for use in storage containers. PES can be processed cost-effectively in various forms, e.g. as a textile, film or fiber.

[0029] NR has excellent elasticity with an exceptional resilience, even under repeated load. As a result, the self-discharge of the storage container can be safely realized even after several runs. NR has high tear and abrasion resistance, making it particularly suitable for use under high mechanical loads. In addition to its high temperature resistance in the range from -50 °C to +70 °C, NR is biodegradable as a natural product and therefore more environmentally friendly and sustainable than synthetic rubber types.

[0030] Alternatively or additionally, it may be envisaged that at least one belt element, preferably all belt elements, has / have a force of at least 200 N at 50 % elongation. The force / elongation behavior of the belt elements can be determined using DIN EN ISO 13934-1.

[0031] A high force-elongation behavior (also known as elongation at break) of a material offers several advantages, in particular in terms of its performance and possible applications. Materials with a high force-elongation behavior can absorb greater loads without breaking or tearing immediately. They are able to absorb sudden or high forces, which increases their durability. Such materials can absorb energy effectively, for example in the event of impacts or heavy loads, without suffering permanent damage. In addition, materials with high elongation behavior can adapt better to changes in shape or size, which makes them more versatile. They are less susceptible to cracking or breaking if they are stressed beyond their original shape. In safety-relevant applications, e.g. ropes, belts or safety nets, a high force-elongation behavior ensures that the material does not suddenly fail, but is visibly deformed beforehand. This can increase safety when handling the storage container. In particular, such materials, which can stretch considerably without losing their structure, are more resistant to repeated stress. By using belt elements with a high force / elongation behavior, the service life of the storage container can be extended.

[0032] Alternatively or additionally, it may be envisaged that at least one belt element, preferably all belt elements, is / are shaped as a flat belt or cable. In particular, at least one belt element, preferably all belt elements, has / have a width of at least 50 millimeters. In particular, at least one belt element, preferably all belt elements, has / have a width of at most 100 millimeters. A flat belt is a flat, belt-shaped material or product. The shape is characterized by a low thickness and a constant width. A cable is a longitudinal element shaped round in cross-section. The belt elements produced as flat straps and / or cables can be shaped flexibly so that they can adapt to the contour of the wall of the storage container depending on the situation. They are suitable in particular for applications where high tensile forces are required for self-discharge.

[0033] Alternatively or additionally, it may be envisaged that at least one belt element, preferably all belt elements, has / have a weight of at least 100 grams per meter, in particular at least 125 grams per meter. In particular, at least one belt element, preferably all belt elements, has / have a maximum weight of 200 grams per meter, in particular a maximum of 175 grams per meter. In particular, this also applies to the at least one additional belt element. This makes it possible to reduce the weight of the storage container.

[0034] Alternatively or additionally, it may be envisaged that the storage container has a capacity of at least 9 cubic meters, preferably at least 15 cubic meters. In particular, it is intended that the storage has a capacity of at most 35 cubic meters. This makes it possible to transport large quantities of goods. This simplifies transportation and reduces the logistical effort.

[0035] The task is further solved by a transport device with a storage container, which can be designed and further developed as described above, comprising: a frame construction for holding the storage container; an inlet unit arranged on the frame construction and connected to the wall in the area of the inlet opening for opening and closing the inlet opening; an outlet unit arranged on the frame construction and connected to the wall in the area of the outlet opening for opening and closing the outlet opening; a plurality of holding devices for fastening the storage container to the frame construction.

[0036] The frame construction allows the storage container to be easily and safely filled, stored, transported and emptied within the transport device. In particular, the inlet unit is arranged on the top of the frame construction and is connected to the wall of the storage container in the area of the inlet opening. This allows the goods to be transported to be let in vertically from above into the storage container. In particular, the outlet unit is arranged on the underside of the frame construction and is connected to the wall of the storage container in the area of the outlet opening. This allows the goods to be transported to exit vertically below the storage container during the unloading process. Thanks to the large number of holding devices, the storage container can be securely fastened to the frame construction. In particular, the storage container is attached to the upper area of the frame construction. This means that the storage container is only connected to the frame construction via the outlet unit, the inlet unit and the holding devices. Between the upper area and the lower area of the frame construction, the storage container can deform elastically independently of the frame construction. In the upper area of the frame construction, the storage container has an essentially square cross-section which, when loaded, tapers continuously along the perpendicular bisector of the storage container to a round cross-section up to the outlet opening.

[0037] Alternatively or additionally, it may be envisaged that wherein the frame construction has external dimensions of at least 2200 × 2000 × 2000 [millimeters], in particular at least 2800 × 2200 × 2300 [millimeters], In particular, the frame construction has an external dimension of at most 6200 × 2600 × 2800 [millimeters], in particular at most 6100 × 2500 × 2600 [millimeters]. This means that the transport device can have the dimensions of an 8-foot container, in particular a 10-foot container and preferably a 20-foot container. This means that the transport device can be transported through standardized dimensions by truck, rail, ship and / or container. In particular, several transport devices can be stacked on top of each other to save space.

[0038] Alternatively or additionally, it may be envisaged that the frame construction has a plurality of recesses extending in the horizontal direction for receiving the forks of a forklift truck. In particular, it is provided that the frame construction has a plurality of coupling elements for coupling the frame construction to a crane. The transport device can thus be used flexibly in that it is compatible with the existing infrastructure, for example with cranes, forklift trucks, container stackers or the like. This favors simple and thus cost-effective handling of the transport device.

[0039] Alternatively or additionally, it may be envisaged that the inlet unit and / or the outlet unit each has / have a closing device for opening and closing the inlet opening and / or the outlet opening of the wall. The respective closing device ensures that the goods to be transported can be safely filled into the storage container. This also prevents the goods to be transported from escaping unintentionally during storage and transportation.

[0040] In particular, it is provided that the plurality of belt elements are each attached by the first end to the frame construction. In particular, the plurality of belt elements are each attached by the second end in a lower section of the first area of the wall. In particular, the plurality of belt elements extend diagonally along the wall from the frame construction to the lower section. In particular, the plurality of belt elements extend diagonally along the wall from the lower section to the frame construction. In particular, a belt element crosses at least one further belt element, in particular at least two further belt elements, preferably three further belt elements, at different positions on the wall. The belt elements are attached to the frame construction via a plurality of fastening elements arranged in the upper area of the frame construction. The fastening elements are arranged in particular in the area of the holding devices.Brief description of the drawings

[0041] The following is a more detailed description of a preferred technical solution with reference to the accompanying drawings using preferred embodiments. The term "figure" is abbreviated to "Fig." in the drawings.

[0042] In the drawings shows Fig. 1a side view of a first embodiment of a transport device in a filled state; Fig. 2a perspective view of the transport device according to Fig. 1 in a emptied state; Fig. 3a schematic view of a storage container in a filled state; Fig. 4a schematic side view of a transport device; and Fig. 5a perspective view of the transport device according to Fig. 4. Detailed description of the drawings

[0043] The described embodiments are merely examples which can be modified and / or supplemented in various ways within the scope of the claims. Each feature, which is described for a particular embodiment, can be used independently or in combination with other features in any other embodiment example. Each feature, which is described for an embodiment example of a certain claim category, can also be used in a corresponding manner in an embodiment example of a different claim category.

[0044] Figure 1 shows a side view of a first embodiment of a transport device 10 in a filled state with a storage container 12 for receiving goods to be transported, in particular powdery bulk goods and / or liquids, comprising an elastically deformable wall 14 and a plurality of elastically deformable belt elements 16 arranged on the wall 14, which extend at least partially along the outer surface of the wall 14, wherein the storage container 12 is shaped for carrying out a self-discharge through the elastic wall 14 and the elastic belt elements 16. The wall 14 has a first area 18 and a second area 20 adjacent below the first area 18, wherein the belt elements 16 are disposed substantially crosswise in the first area 18 of the wall 14. In addition, the wall 14 has, in a transition region between the first area 18 and the second area 20, an additional belt element 22 which at least partially encloses the wall 14 circumferentially in the horizontal direction and is elastically deformable, wherein the additional belt element 22 is arranged on the wall 14 coaxially with respect to the perpendicular bisector of the storage container 12. All belt elements 16, 22 have a plurality of guiding elements 24 for guiding the belt elements 16, 22 along the wall. In the filled state, the wall 14 and the belt elements 16, 22 are elastically deformed. The resulting forces act on the goods to be transported inside the storage container 12 in the direction of the perpendicular bisector of the storage container 12. These forces cause the storage container 12 to self-discharge during the unloading process. The transport device 10 further comprises a frame construction 26 for receiving the storage container 12, wherein the frame construction 26 comprises a plurality of recesses 28 extending in the horizontal direction for receiving the forks of a forklift truck and a plurality of coupling elements 30 for coupling the frame construction 26 to a crane. The transport device 10 can thus be used flexibly in that it is compatible with the existing infrastructure, for example with cranes, forklift trucks, container stackers or the like.

[0045] This favors simple and thus cost-effective handling of the transport device 10.

[0046] Figure 2 shows a perspective view of the transport device according to Fig. 1 in an emptied state. The wall 14 of the storage container 12 is compressed in the direction of the perpendicular bisector by the plurality of belt elements 16, 22. In the first area 18 of the wall 14, the wall 14 is partially stretched vertically upwards, whereby a passage 32 extending substantially vertically is formed in the second area 20 of the wall 14. The first area 18 and the second area 20 are shaped like a funnel or have a Y-shape. In this way, it can be ensured that the entire goods to be transported emerge from the storage container 12 during the unloading process.

[0047] Figure 3 shows a schematic view of a storage container 12 in a filled state with a preferred arrangement of the belt elements 16, 22. The belt elements 16 have a first end 34 and a second end 36, wherein the belt elements 16 are each fastened with the first end 34 in an upper section of the first area 18 of the wall 14 and are each fastened with the second end 36 in a lower section of the first area 18 of the wall 14. The belt elements 16 extend diagonally along the wall 14 from the upper section to the lower section, with each belt element 16 being crossed by three further belt elements 16 at different positions on the wall 14. Such an arrangement ensures that the wall 14 is essentially evenly loaded by the belt force during the filling process and the unloading process. The guiding elements 24 also favor an even distribution of the belt elements 16, 22 along the wall 14.

[0048] Figure 4 shows a schematic side view of a transport device 10 without belt elements 16, 22. The storage container has an inlet opening 38 arranged on the wall 14 for letting in the goods to be transported and an outlet opening 40 arranged on the wall 14 for discharging the goods to be transported. The transport device 10 has an inlet unit 42 arranged on the frame construction 26 and connected to the wall 14 in the region of the inlet opening 38 for opening and closing the inlet opening 38, and an outlet unit 44 arranged on the frame construction 26 and connected to the wall 14 in the region of the outlet opening 40 for opening and closing the outlet opening 40. The inlet opening 38, the inlet unit 42, the outlet opening 40 and the outlet unit 44 are arranged coaxially to the perpendicular bisector 46 of the storage container 12.
