Definitions
- the invention relates to a device for emptying, filling, storing and transporting large-volume containers of all kinds.
- Bulk goods are increasingly referred to as big bags in large-volume containers (> 1m 3 ) and, depending on their density, are packed with correspondingly high weights from a few hundred kilos up to tons.
- Stationary systems are known for emptying large-volume containers, for filling, emptying, transporting and storing the container, the handling of which, owing to the large volumes and weights of the large-volume container.
- a big bag or a container is very problematic, since this requires very complex plant equipment which, on the one hand, is difficult to operate and, on the other hand, requires very complex storage and transport.
- These systems ie essentially filling and emptying stations, are generally stationary units into which the large-volume container, in particular a big bag, has to be introduced. Is z. B.
- large-volume containers especially big bags
- With the destruction of the bottom of the large-volume container further use of the large-volume container, in particular a big bag, is made impossible.
- Large-volume containers are generally stored by directly placing the filled large-volume containers Releases themselves or with the aid of pallets on the floor of a storage area or by stacking them pyramid-shaped on a storage area. Storage in high-bay warehouses is only possible to a limited extent.
- an emptying device for large-volume containers which consists of a frame in which the large-volume container to be emptied, in particular a big bag, can be hung, the large-volume container which can be suspended there being connected at the lower end to a funnel-shaped outlet is provided, this device being suitable only for a very specific type of large-volume container, namely cylindrical "big bags".
- the disadvantage here is that the large-volume container can only be hung into the device with very considerable effort, and that this emptying device also does not allow for a meterable emptying, since this device does not have a closure with which the emptying of the large-volume container can be regulated in a metered manner. In addition, it is also disadvantageous that this emptying device is difficult to store and transport leaves.
- an emptying device for large-volume containers which consists of a frame which is provided with four feet, which are arranged at the corners, and which is provided with a base plate, two of the four feet after are extended at the top by stanchions, which are designed in a gallows-shaped manner, so that the large-volume container to be emptied, preferably a big bag, can be hung on the short, protruding struts and in which a central opening is provided in the base plate, which is provided with a hatch , with which, however, no metered and clean emptying of the large-volume container, in particular a big bag, is made possible, since this does not provide a seal necessary for clean emptying having.
- a device for emptying pourable bulk material in which the emptying by means of a suction device, such as. B. a suction pipe, a suction button or the like and which consists of a collapsible frame for hanging the large-volume containers, which comprises a lever for stretching the large-volume containers, which consists of a cable and pulleys, each on the upper ends of the four stanchions or posts, which are arranged at the corners, over which the lever cables of the large-volume container are guided.
- a suction device such as. B. a suction pipe, a suction button or the like and which consists of a collapsible frame for hanging the large-volume containers, which comprises a lever for stretching the large-volume containers, which consists of a cable and pulleys, each on the upper ends of the four stanchions or posts, which are arranged at the corners, over which the lever cables of the large-volume container are guided.
- an emptying device which at the same time represents a large-volume container for flowable masses, which consists of a receiving frame which has a base plate, which has a side wall which serves to support the bag and which is telescopic is provided. Furthermore, this device is provided at the upper end with a connection device for a hoist to which a hoist bracket can be connected in such a way that the large-volume container, for. B. a big bag can be lowered when emptying, so that emptying after takes place below and with which the large-volume container can be pulled upwards during filling, so that the large-volume container can be filled with the contents from below.
- an opening is provided in the lower area, which is provided with a line through which the large-volume container can be filled.
- the disadvantage here is that neither a metered emptying of the large-volume container nor a metered filling is possible with this device, since this has no adjustable closure with which the emptying or filling can be regulated.
- an emptying device for large bags which has two essentially flat, preferably structurally identical side elements, each of which forms a front and rear foot area and at least one head area, which have a vertically operating lifting device, the connection zones for cross-connection parts have and which are higher than the simple height of a suspended large-volume container, and which has a lifting crossbar which can be detachably arranged between the lifting devices, which has holding means for the hanging brackets and has at least one cross-connecting part for cross-bracing.
- the invention is therefore based on the object of providing a device for large-volume containers of the type mentioned at the beginning, with which both controllable emptying and filling is possible and which is transportable and storable, which is inexpensive and can be used for all commercially available large-volume containers, in particular big bags.
- the emptying device for large-volume containers consists of a transport aid which consists of a frame which has four stacking feet, each of which is connected to one another with lath-like cross struts, so that they are arranged approximately in a square and those with four stanchions are connected, which are designed as hollow bodies, for receiving an integrated lifting mechanism that supports the emptying process of the large-volume container and ensures the complete emptying of the large-volume container.
- the transport aid designed as a frame is provided with a base plate which is provided with a central opening which serves to receive the metering and closing mechanism, which consists of a base plate which is connected to the base plate, and which for Includes the actual closure.
- the base plate can be designed as a full body or as a pallet.
- the base plate can be formed continuously or only in sections, i. H. that it is then slat-shaped, whereby a certain weight saving is achieved which enables easy transportation of the device for large-volume containers.
- the locking mechanism is designed so that both the inlet and the outlet connection of the large-volume container can be easily inserted into the closure.
- the closure is constructed in such a way that at least two ropes, tapes, straps or chains lie concentrically around the spout, which is also made of a flexible material and is generally centered on the underside of the large-volume container, and its diameter is consistent. Increase or decrease continuously.
- the at least two ropes are attached symmetrically, opposite and freely to a rotating ring at one end, alternatively designs with a larger number of ropes are also conceivable.
- the opposite end of each rope is designed in such a way that lengthening and shortening is permitted. This can e.g. B. by using suitable pulling mechanisms, such as. B.
- tension spring gas tension spring directly or with appropriate design of pressure mechanisms indirectly via pressure, gas spring or the like.
- z. B also use a rubber or elastic band limited in its expansion.
- the pull and push mechanisms are suitably connected to the housing of the closure.
- a stop device incorporated in the rope construction prevents the tension mechanisms from being overstretched and tightens the corresponding ropes.
- rods or flexible rods made of carbon fiber, synthetic fiber, metal fiber or glass fiber can be used, which are only rotatably and non-displaceably fastened with one end to the rotatable ring, the ring being provided with openings through which the end fastened there the rods can be pushed so that they are slidably supported, whereby a spring can be pushed onto the end of the rods, which spring is connected to a stopper attached to the outer end of the rod, so that they can bend around the outlet nozzle by bending, so that their cross section can be reduced accordingly by bending the rods when closing and increased when opening.
- pins are arranged on the outer edge of the base plate of the locking mechanism, which are provided in the upper area with a circular, cylindrical or square opening through which the free end of the rods can be pushed so that they can be moved in the pins are stored, the end over protrudes the pin so that a spring can be pushed onto the end, which is connected to a stopper arranged at the outer end of the rods, which limits the displaceability of the rods.
- It can also be rods with a wire core with plastic sheathing that are bendable.
- the rotatable ring is designed in such a way that it can be driven indirectly or directly via a suitable drive.
- a suitable drive this is done, for. B. via a suitable toothing attached to or on the ring, which engages in the driving toothing of another gear.
- the drive instead of the gear via z. B. a rope, a belt or chain hoists. If the drive is made by chain hoists, then it is a chain or belt transmission in which the power transmission between the sprocket and chain takes place in a form-fitting manner and with a superimposed frictional connection or only frictionally, the ratio depending on the diameter and tooth ratio of the chain wheels.
- the chain can be designed as a drive, bush, roller, tooth, non-positive roller, round steel, gall or load or conveyor chain.
- a belt can also be arranged, with a pulley and a belt ring.
- the belt transmission is suitable for small and medium outputs of torques and speeds and is used to bridge large, roughly tolerated center distances and to protect against overload by slipping and ensures extremely quiet and low-noise operation, whereas a chain transmission for medium performance and medium-sized roughly toleranced center distances is suitable and represents a cost-effective, easily accessible and robust system.
- the belt can either be designed as a single-layer textile belt, multi-layer textile belt, polyester cord belt or as a belt belt with wide drawstrings, whereby it is composed of an upper layer, also a cover layer, a middle layer, the tensile layer and a lower layer, the running layer.
- the pull layer can either be formed in one or more layers, generally two, three or more layers can be provided, each of which can have a different structure. They usually consist of polyamide, polyamide in combination with cotton, polyester or a combination of cotton, polyamide and polyester. The layers generally have a rod-shaped structure, but a honeycomb or web structure is also conceivable.
- the running layers usually consist of an elastomer, polyurethane, balata or chrome leather.
- synchronous belts or timing belts can also be used, the belt bodies of which are made of neoprene or polyurethane with tensile cords made of high-strength glass fibers or steel, Kevlar or polyester cord, which are wound helically in the belts, which are usually endlessly produced in standard lengths.
- the belts can be single or double toothed, the teeth being square, rectangular, semicircular, trapezoidal, triangular or polygonal.
- a hydraulic drive can also be used for the drive.
- the aforementioned drive options are moved via a self-locking or non-self-locking worm gear.
- the worm gear is driven manually, electrically, pneumatically or hydraulically.

- each stanchion or each post or the post of the tubular frame a lifting mechanism is attached, which is either integrated in each stanchion or post or is arranged on the stanchions, in which this is directly on the Is attached to the outside of the stanchions or posts, or indirectly, in which case a further short tube is then arranged on the outside of each stanchion, which serves to accommodate the lifting mechanism.
- the lifting mechanism is designed as a gas pressure spring, but can also be designed as a hydraulic piston, as a spring or as a cable or chain hoist, which can be actuated electrically, pneumatically, hydraulically or manually.
- the lifting mechanism works by hanging the large-volume container between the stanchions or posts and connecting it to the lifting mechanism in a suitable manner by means of a self-tightening strap holder, with flexible containers, which are generally designed with carrying straps, by hanging the respective one Loops on the respective lifting mechanism.
- the lifting mechanisms are triggered by the weight loss of the large-volume container and raise the large-volume container, the stroke being automatically adjusted in proportion to the emptied quantity of bulk material and the floor being raised when the lift is fully extended formed the large-volume container into a conical funnel.
- the complete emptying of the free-flowing bulk material from the large-volume container is thus guaranteed.
- a self-tightening carrying strap holder is provided for hanging a filled big bag in the lifting device, which enables the respective strap to be directly received for the purpose of introducing a filled, large-volume container into the lifting device.
- the carrying straps of the large-volume container can each be placed in a self-tightening carrying strap holder such that when a loaded, large-volume container in particular, which is generally inserted into its carrying straps, is inserted, a holder at the lower end of the carrying loop, that is, in the vicinity of the large-volume container is attached and can be connected with a transport or lifting device and is used for lifting loads, the upper segment or the loop remaining freely movable and being used for connection to the lifting mechanism of the pallet.
- the carrying loop of the large-volume container is introduced into the holder, in which the latch, which can be freely moved down and up and is rotatable, is folded up, ie out of the actual holding area of the holder.
- the loop which is folded into a loop, is pushed through the opening of the holder and the latch is folded in and podded against the stop.
- the latch moves firmly to the lower stop of the holder and thus pulls on the end of the carrying loop which is connected to the large-volume container and thus lashes down.
- the strap holder itself is suitably at its upper end with the lifting means such. B. attached to a load or support cross. Due to the mutual force, ie the weight of the large-volume container downwards and the upward force of the lifting means at the connection to the hoist, the wrist strap holds self-locking in the wrist strap holder. The free end of the strap can now be hooked onto the lifting device and the filled, large-volume container can be lowered into the device. To unlock the now between the large-volume container and the Lifting device located and under tension due to the strap is usually pulled out sideways. The carrying loop under tension relieves the load completely and the carrying loop holder is free.
- the flexible, large-volume container used is equipped or modified in its carrying strap design in such a way that when a filled container, which is generally introduced on its carrying straps, is inserted, a further carrying strap is provided at each corner of the flexible, large-volume one Container is provided, or in the case of a single loop in each corner, this is divided into two loop segments by knotting themselves in the center, so that the upper loop segment is freely movable and can be used to connect to the lifting mechanism of the pallet.
- the carrying loop holder can also have a plate as a tensioning element, a clamp or the like instead of a latch.
- the transport aids are a box in which the floor is designed as a pallet, with a centrally arranged opening, for receiving the locking mechanism, the walls of which can be either full-walled or partially walled.
- Posts are arranged in the corners of the box, which serve on the one hand to connect the walls and on the other hand to stiffen the box.
- These are designed as solid or hollow bodies, so that in each case a lifting device is arranged in their upper ends, the posts designed as solid bodies having cavities in the upper region for receiving the lifting device.
- the corners can also be reinforced with plate-like support fabrics, which are arranged diagonally in front of the posts on the inside of the box.
- the walls can be made of wood, recycled panels, plastic, metal, Carbon or glass fiber exist or they can consist of multi-glued layers of wood and layers of recycled boards, which have a core consisting either of wood or plastic, which is surrounded by metal cover layers.
- the walls can have a polyurethane core, which is provided with a carbon fiber or glass fiber reinforced outer layer.
- the walls can optionally be designed as a solid body or as a hollow body, which in the case of the part-walled design can be slat-shaped or rod-shaped, which can be arranged either transversely, vertically or diagonally. Alternatively, they can be rod-shaped, lamellar or lattice-shaped.
- the lattice-like walls can also be provided with a pattern which is formed by an alternation of openings and change cuts, the wall sections being able to have many different shapes, so that many different patterns can be formed.
- crescent-shaped patterns, lattice-shaped patterns, columnar patterns, rod-shaped patterns, snowflake-like patterns, bell-like patterns or other types of patterns can be formed.
- the base plate can be either full or partial and can be slat-shaped, rust-shaped, lattice-shaped, lamellar, web-like or honeycomb-like, alternatively the base plate can also have an x, double X, Y or double Y structure.
- the transport aid can consist of a base plate, which can be designed as a stacking or Euro pallet and in the corners of which an opening is arranged, for receiving posts or stanchions, which can be provided with stilts or stacking feet at their lower ends, the Stilts or stacking feet also directly on the base plate e.g. B. by means of screws or the like can be attached.
- the transport aids can also be designed as a holding frame, with an integrated or attached holding mechanism to support the emptying process by lifting and ensuring complete emptying by shaping the bottom of the large-volume container into a conical shape, the lifting mechanism only being achieved when a predetermined degree of partial emptying has been reached Free-flowing bulk material in the container is triggered,
- the holding frame can consist of a suitable frame, tube frame or of posts which are arranged on the base plate designed as a pallet.
- a lifting mechanism is attached or integrated in the upper area of each stanchion or each post or post of the tubular frame.
- the flexible container is suspended between the posts and suitably connected to each of the lifting mechanisms.
- the design of the posts further enables the stacking of several pallets on top of one another in the case of filled and partially filled big bags and by pulling out, folding or folding over the posts or the frame, the stacking of the pallets themselves.
- the advantage of this device for large-volume containers is that there is a significant reduction in the necessary handling and system outlay, as well as a considerable saving of time that the use of large-volume containers makes necessary.
- this enables the partial or automatic introduction and removal of the emptying device via automatic pallet conveyor systems into a filling station for large-volume containers of all types, and it is possible for the large-volume containers of all types to be emptied or also filled with this emptying device .
- the possibility of automatically docking the filling support of a filling device is offered, and it is possible to store filled and partially emptied large-volume containers, in particular big bags, in high-bay warehouses. A significantly reduced empty volume results in the event that the device is temporarily stored or must be shipped as empties.
- the use of the device for already filled large-volume containers is possible by using the design of the carrying straps and with the self-tightening holder.
- the device can be used as a system for the transport, storage and filling as well as the partial and complete emptying of large-volume containers.
- the device significantly simplifies the system and manual work required in all handling areas, in which the large-volume container, in particular a big bag, remains in the device for its entire life cycle and by means of commercially available transport and handling devices already found in many companies, such as, for. B. forklifts are used and can also be used for the automation of loading and unloading systems for large-volume containers.
- the device offers an inexpensive alternative to the handling devices previously available on the market.
- the dosing and sealing mechanism integrated in the device enables controlled emptying of the container contents.
- the locking mechanism had to be specially developed for use in a pallet to ensure that the pallet can still be handled with the usual transport equipment.
- the dosing and locking mechanism is characterized by its simplicity, a low overall height and minimized external dimensions and in no way influences the usual uses of the pallet.
- the dosing and locking mechanism is operated manually with a hand crank, handwheel or via electrical, electromagnetic, hydraulic or pneumatic drives.
- the drive shaft of the closure In the case of a stationary unloading station, the drive shaft of the closure is designed so that an electric, electromagnetic, hydraulic or pneumatic drive can dock automatically and the emptying can be controlled manually or automatically.
- the integration into bulk material conveying systems using commercially available docking stations with the outlet nozzle of the large-volume container protruding through the device remains guaranteed.
- the invention further opens up the possibility of using large-volume containers to users who, up to now, have been denied the use of large-volume containers due to the high investment volume for the necessary plant outlay or space, and opens up further potential for the use of large-volume containers.
- the large-volume container stands on the base plate designed as a pallet and hangs on its carrying loops in the device
- commercially available automated pallet transport and handling systems can be used.
- the device also eliminates the time-consuming manual tasks that were required to handle the large-volume container in its conventional use, thereby achieving significant time savings.
- the introduction of filled, large-volume containers or their replacement for use in the same device is easier to handle and can be carried out in a very short time.
- the exchange of filled, large-volume containers is possible by using the carrying loop design and in particular the self-tightening bracket.
- the problem with introducing partially or filled large-volume containers into the device is that the same strap is also for hanging in the Lifting device is needed. Assuming that the large-volume container hangs on the hook of a carrying cross, the holder of the lifting mechanism can only be brought into the same carrying loop below the hook of the carrying cross.
- the lifting mechanisms When the large-volume container is lowered into the device, the lifting mechanisms are pressurized so that when the large-volume container is inserted, the hook of the carrying cross is clamped in the carrying loop by the accommodation of the lifting mechanism.
- the cross hook can only be removed under difficult conditions. Taking into account the design of the large-volume containers with 2 carrying straps in each corner or by knotting each carrying strap in the middle in two segments, or the use of the self-tightening carrying strap holder, one strap or one loop segment always remains free of load and free to move.
- the base plate designed as a pallet can be modified in such a way that it is freely accessible through suitable, commercially available transport and handling devices, such as, for. b. Forklifts, automatic pallets, stacking and unstacking systems, pallet trucks etc. can be used without restriction from all sides.

- the posts of the side walls each have at their upper end hanging stacking heads which can be threaded into the plate-like recess of the stacking feet, which also serve to fasten loops of large-volume containers, in which they have an essentially trapezoidal cutout, which is also circular , rectangular, square, hexagonal, octagonal or polygonal or alternatively have one or more hooks which are attached in such a way that the loops of the large bag cannot be pinched or sheared off by the stacking feet of a second pallet placed above them, which is thereby achieved, that the cutout has a sufficient distance from the outer edge of the stacking button.
- This device is suitable for hanging large-volume containers with at least four or even more hanging loops, so that the large-volume container suspended thereon can be tipped over to at least two points and the large-volume container can be attached in such a way that it does not fall out, which is achieved in that the large-volume container is fastened to the hanging stack buttons with loops when tipping and at least two cutouts or hooks are attached to the base frame as a fastening option for the lower loops of the large-volume container for hardening - are located so that the large-volume container remains fastened with a load even when turned up to more than 180 °.
- the carriers with which the connecting cross members of the frame are connected to one another can be designed as a hollow body, so that the tines of the forklift truck can easily engage in them, these being rectangular, round, hexagonal, octagonal or polygonal.
- the profile strips can also be designed as cross strips, so that the tines of the forklift truck can engage from all sides, alternatively tubes or box-shaped strips can be arranged on the undersides of the carriers, into which the tines of the forklift truck can engage, the carriers then being used as Full body are trained.
