Description

    Technical area
  • The invention relates to a device for emptying, filling, storage and transport of large-volume containers of all kinds.
  • Bulk goods are increasingly in large-volume containers (> 1m 3 ) hereinafter referred to as big bags and packed according to density with correspondingly high weights from a few hundred kilos up to tons.
  • State of the art
  • For emptying large-volume containers stationary systems are known for filling, emptying, for transport and storage of the container whose handling due to the large volume and weights of the large-volume container z. As a big bag or a container is very problematic, since this requires very complex equipment systems, which are difficult to use and on the other hand require a very complex storage and transport. In these systems, ie essentially filling and emptying stations are generally stationary units in which the large-volume container, in particular a big bag must be introduced. Is z. For example, if an unloading station is not available, large-volume containers, in particular big bags, can also be emptied via suction devices and by destruction, ie by slitting the bottom of the large-volume container, on an industrial scale. With the destruction of the bottom of the large-volume container further use of the large-volume container, in particular a big bag is impossible. The storage of large-volume containers is generally carried out by directly placing the filled large-volume containers itself or with the aid of pallets on the floor of a storage area or by pyramid-shaped stacking on a storage area. Storage in high-level storage is only possible to a limited extent.
  • Discharge devices are known from the prior art. Thus, from GB-PS 2 014 965 an emptying device for large-volume containers is known, which consists of a frame in which the large-volume container to be emptied, in particular a big bag can be mounted, the there attachable large-volume container at the bottom with a funnel-shaped spout is provided, this device is only suitable for a very specific type of large-volume containers, namely for cylindrical "big bags". The disadvantage here is that the hooking of the large-volume container in the device is possible only at a very considerable expense, and that with this emptying device no metered emptying is possible, since this device has no closure with which the emptying of the large-volume container controlled metered can be. In addition, it is disadvantageous that this emptying device is difficult to store and transport.
  • From GB-PS 2 066 220 an emptying device for large-volume containers is known, 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, wherein two of the four feet after are extended above by stakes, which are gallows-shaped, so that at the short protruding struts to be emptied large-volume container, preferably a big bag can be hung and in which further in the bottom plate, a central opening is arranged, which is provided with a hatch , but with no metered and clean emptying of the large-volume container, in particular a big bag is possible, since this is not necessary for a clean emptying seal having. Another disadvantage is that this emptying device is difficult to handle and is difficult to store, since storage of this emptying device is not possible one above the other, due to the design of the frame for hanging the large-volume container. In addition, with this device, no complete emptying of the large-volume container is possible.
  • From DE-OS 197 41 108, a device for emptying pourable bulk material is known in which the emptying by means of a suction device, such. B. a suction tube, a suction knob or the like and which consists of a collapsible for suspending the large-volume containers frame, which includes a lever to stretch the bulky 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, exists over which the lever ropes of the bulky container are guided. The disadvantage here is that the lever device used there is suitable only for large-volume containers up to a certain weight and can not be used indefinitely for any type of large-volume containers and that this emptying device has no closure with which a metered or controllable emptying is possible ,
  • DE-GbM 94 07 507.7 an emptying device is known, which also represents a large-volume container for flowable masses, which consists of a receiving frame, which has a bottom plate, which serves with a lateral wall, which serves to support the bag and which is formed telescopically, is provided. Furthermore, this device is provided at the upper end with a connection device for a hoist, to which a hoist strap is connected in such a way to which the large-volume container, for. B. a big bag can be lowered when emptying down so that emptying after at the bottom and with which the large-volume container can be pulled up when filling, so that the large-volume container can be equipped with the contents from below. For this purpose, an opening is provided in the lower region, which is provided with a line through which the large-volume container can be filled. The disadvantage here is that with this device neither a metered emptying of the bulky container nor a metered filling is possible because it has no adjustable closure with which the emptying or filling can be regulated.
  • From DE-OS 199 45 195 an emptying device for large bags is known, which has two substantially flat, preferably identical side elements, each forming a front and rear foot area and at least one head portion having a vertically operating lifting device, the connection zones for cross-connection parts and which are higher than the simple height of a suspended large-volume container, and which can be arranged between the lifting devices releasably Hubtraverse having holding means for the hanging tabs and at least one transverse connecting part for a cross-brace. The disadvantage here is that even with this device no metered emptying of the large-volume container is possible because this device also has no metered closure, with a clean and controlled gradual emptying of the large-volume container is possible. The disadvantage here is further that this device is transportable and storable only with great effort.
  • From FR 2 644 135 an emptying device for big bags is known, which corresponds to the preamble of entitlement 1, and which consists of a frame consisting of four stanchions, which are formed as a hollow body and connected at its lower end with one foot are and in their lower part are each connected to bars. The upper ends of the stanchions are designed so that they can accommodate four arms, which in the upper area by means of Cross struts are interconnected and form a lifting device that must be operated with an external hoist. In the lower area are arranged opposite to each other arranged angle at the front of the stanchions, which are resiliently mounted, in which they are connected to springs which are arranged in the two stanchions which form the front. On the angles, the plate in which the closure is arranged stored.
  • Presentation of the invention, object, solution, advantages
  • The invention is therefore an object of the invention to provide a device for large-volume containers of the type mentioned, with both a controllable and controllable emptying and filling is possible and is transportable and storable to create, which is inexpensive and commercially available for all bulky containers, especially big bags, can be used.
  • This object is achieved by the features mentioned in claim 1.
  • For this purpose, it is provided that the emptying device for large-volume containers consists of a transport aid, which consists of a frame having four stacking feet, which are connected to each other with lath-like cross braces so that they are arranged approximately square and firmly connected to four stanchions are, which are formed as a hollow body, for receiving an integrated lifting mechanism that supports the emptying of the large-volume container and ensures the complete emptying of the large-volume container. It is also intended that as a frame formed transport means is provided with a bottom 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 bottom plate, and which serves to receive the actual closure. The bottom plate may be formed as a solid body, or as a pallet. In addition, the bottom plate may be formed continuously or only in sections, ie that this is then lath-shaped, whereby a certain weight saving is achieved, which allows easy transport of the device for large-volume containers.
  • The locking mechanism is designed so that both the inlet and the outlet of the large-volume container can be easily inserted into the closure. The closure is in this case constructed so that at least two ropes, straps, belts or chains concentrically surround the also consisting of a flexible material and located generally centrally on the underside of the large-volume container outlet and continuously reduce or increase in diameter , The at least two ropes are symmetrical at one end, opposite and freely movable attached to a rotatable ring, with alternative embodiments with a larger number of ropes are conceivable. The opposite end of each rope is designed so that an extension and shortening is allowed. This can be z. B. by using suitable tension mechanisms, such. B. tension spring, gas spring directly or with appropriate interpretation of pressure mechanisms indirectly via pressure, gas spring or the like. Instead of the combination of rope and tension spring, as shown, z. B. also be limited in its expansion rubber or rubber band used. The pulling and pushing mechanisms are suitably connected to the housing of the closure. An introduced into the rope construction stop device prevents overstretching of the pulling mechanisms and tightens the corresponding ropes.
  • Instead of ropes and rods rods of carbon fiber, synthetic fiber, metal fiber or glass fiber can be used, which are attached only rotatably and non-displaceably with the one end on the rotatable ring, wherein the ring is provided with openings through which the end attached there the rods can be pushed so that they are slidably mounted, wherein on the end of the rods, a spring can be pushed, which is connected to a stopper attached to the outer end of the rod, so that they can bend around the outlet nozzle, so that their cross section can be reduced by bending the rods accordingly when closing and can be increased when opening. It is provided that at the outer edge of the base plate of the Verschlussmechanismusses several pins are arranged, which are provided in the upper part with a circular, cylindrical or square opening through which the free end of the rods can be pushed so that they slidably in the pins are mounted, wherein the end protrudes beyond the pin, so that on the end of a spring can be pushed, which is connected to a arranged at the outer end of the rods stopper, by which the displaceability of the rods is limited. It may also be rods with Drahtkem with plastic coating, which are bendable.
  • The rotatable ring is designed so that it can be indirectly or directly driven by a suitable drive. In the case of an indirect drive this z. B. via a suitable with or attached to the ring toothing, which engages in the driving toothing of another gear. Also, the drive instead of the gear over z. As a rope, a belt or chain hoists done. If the drive by chain hoists, so it is chain or Belt transmission, in which the power transmission between the sprocket and chain is positively and with superimposed frictional engagement or only frictionally engaged, wherein the translation is dependent on the diameter and tooth ratio of the sprockets. The chain can in this case be designed as a drive, bushing, roller, tooth, non-positive roller, round steel, gall or load or conveyor chain. Instead of a chain may also be arranged a belt, with a pulley and a belt ring. The belt drive is suitable for small and medium torques and speeds and is used to bridge large, roughly tolerated center distances and provides overload protection through chutes and ensures extremely quiet and quiet operation, whereas a chain drive for medium power and medium-sized roughly tolerated center distances is a cost-effective, accessible and robust system. The belt may be formed either as a single-ply textile belt, multi-ply textile belt, polyester cord belt or wide belt tension belt, comprising upper layer belts, also cover layer, middle layer, tension layer and lower layer, the running layer. The tension layer may be formed either single-layered or multi-layered, wherein usually two, three or more layers may be provided, each of which may have a different structure. They are usually made of polyamide, polyamide in combination with cotton, polyester or a combination of cotton, polyamide and polyester. The layers usually have a rod-shaped structure, but also a honeycomb or web structure is conceivable. The running layers are usually made of an elastomer, polyurethane, balata or chrome leather. In addition, it is also possible to use synchronous belts or toothed belts whose belt bodies are made of neoprene or polyurethane with tensile strands of high-strength glass fibers or steel, Kevlar or polyester cord, which are helically wound in the belts, which are usually produced in standard lengths. The belts can be single or double toothed, wherein the teeth may be square, rectangular, semicircular, trapezoidal, triangular or polygonal. Instead of a gear transmission can also be used to drive a hydraulic drive.
  • The aforementioned drive options are moved by a self-locking or non-self-locking worm gear. The worm gear is driven manually, electrically, pneumatically or hydraulically. In a direct drive allows a mounted on the outer diameter of the rotatable ring teeth direct drive via a self-locking gear worm that engages directly into the teeth of the rotatable ring and is coupled with manual, electric, pneumatic or hydraulic drives and overload protection for the incoming forces of can have the drives.
  • Alternatively, the drive of the closure can also take place via a circulating chain, which is connected to a motor or the like. For this purpose, a larger number of rotatable pins are arranged in the outer region of the base plate, which also serve for deflecting the chain and which are connected via ropes, chains, straps, straps, rods, wires or the like with the rotatable ring, whereby it is actuated.
  • It is further provided that in the upper part of each Runge or each post or of the post of the tubular frame, a lifting mechanism is mounted, which is integrated either in each stanchion or post or is arranged on the stanchions, in which this directly on the Is mounted outside of the posts or posts, or indirectly, in which case on the outside of each Runge another short tube is arranged, which serves to receive the lifting mechanism. In general, the lifting mechanism is designed as a gas spring, but can also be used as a hydraulic piston, as a spring or as a cable or chain hoist, this can be electrically, pneumatically, hydraulically or manually operated, be formed. The lifting mechanism works by hooking the bulky container between the stanchions or posts and being suitably connected to the lifting mechanism via a self-tightening carrying strap holder, with flexible containers generally designed with carrying loops, by hooking the respective ones Loops on the respective lifting mechanism takes place. When filled state or until reaching the release of the lifting mechanism necessary degree of filling and associated residual weight in the large-volume container, the lifting mechanisms are in the retracted state. Upon reaching the necessary Teilentleerungsgrades of bulk material located in the large volume container solve the lifting mechanisms by the weight loss of the large-volume container and lift the bulky container, wherein the stroke automatically adjusts proportionally to the emptied amount of bulk material and at fully extended Hub of the ground of the large-volume container has been formed into a conical funnel. The complete emptying of the free-flowing bulk material from the large-volume container is thus guaranteed.
  • It is further provided that for mounting a filled big bag in the lifting device a self-lashing carrying strap holder is provided which allows the direct reception of the respective loop for the purpose of introducing a filled large-volume container in the lifting device. The carrying loops of the large-volume container can be introduced in such a way in a self-lashing support strap holder that when introducing in particular a loaded large-volume container, which is generally introduced at its carrying loops, respectively a holder at the lower end of the carrying loop, ie in the vicinity of the large-volume container is attached and can be connected to a transport or lifting means and is used for load-carrying, wherein the upper segment or the loop remains free to move and is used to connect to the lifting mechanism of the pallet. The carrying loop of the large-volume container is introduced into the holder, in which the freely upwardly and downwardly displaceable and rotatable latch upwards, that is folded out of the actual holding area of the holder. The folded into a loop carrying strap is pushed through the opening of the holder and folded the latch and pushed to the stop. By pulling on the shaped loop, the latch firmly moves to the lower stop of the holder and thus pulls on the connected to the large-volume container end of the carrying strap, which thus lashed. The carrying strap holder itself is at its upper end in a suitable manner with the lifting means, such. B. attached a load or carrying cross. Due to the mutual force, ie the weight of the bulky container down and the upward force of the lifting means at the connection to the hoist holds the strap selbstsichemd in the strap loops. The free end of the strap can now be hooked to the lifting device and the filled large-volume container can be lowered into the device. To unlock the now located between the large-volume container and the lifting device and due to the strap under tension holder of the rule is pulled out laterally. The tensioned straps relieve the load completely and the strap holder is free.
  • For this purpose, it may further be provided that the flexible large-volume container used in its carrying loop training is equipped or modified so that upon introduction of a filled container, which is generally introduced at its carrying loops, each a further carrying loop at each corner of the flexible large volume Container is provided, or in the case of a single loop in each corner, this is divided by the central knotting itself into two loop segments, so that the upper loop segment is freely movable and can be used to connect with the lifting mechanism of the pallet.
  • The carrying strap holder may also have a plate as a clamping element, a clip or the like instead of a bolt.
  • With the invention it is achieved that the device can be used as a system for transport, storage and filling and the partial and complete emptying of large-volume containers. The device significantly simplifies the equipment and manual effort required in all areas of operation, in which the large-volume container, in particular a big bag remains its entire life cycle in the device and commercially available, in many companies anyway already found transport and handling facilities such. B. forklift used and can also be used for the automation of loading and unloading systems for large-volume containers. The device offers a cost-effective alternative to the hitherto available on the market handling equipment. The integrated in the device metering and Verschlussmechnismus allows a controlled emptying of the container contents. The shutter mechanism had to be specially designed for use in a pallet, to ensure that the pallet could still be handled with common transport equipment. The dosing and sealing mechanism is characterized by its simplicity, a low height and minimized external dimensions and influences in no way the previously common uses of the range. The dosing and closing mechanism is operated manually with hand crank, handwheel or via electric, electromagnetic, hydraulic or pneumatic drives. 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 discharge can be controlled manually or automatically.
  • By placing the device on a simple pedestal at any suitable location, the integrated metering mechanism can control the discharge of product in the container. The integration into bulk material handling systems using commercially available docking stations with the outlet nozzle of the large-volume container projecting through the device remains ensured. The invention further opens up the use of large-volume containers to users who have hitherto been denied the use of large-volume containers due to high investment volumes for the necessary equipment or space required, the possibility of using large-volume containers and opens up further potential for the use of large-volume containers. The storage and intermediate storage of filled and very specially partially emptied large-volume containers in storage systems, such. B. Hochregallagem is due the not possible collapsing and possibly overhanging the textile container material guaranteed because the large-volume container always hangs in the streamlined state between the stanchions. Removable rigid or collapsible stanchions and stackable devices significantly reduce the space required for storage or transportation of non-in-use units. It can be assumed that a large-volume container once placed in an unloading station remains in this until it is completely emptied, and consequently requires that a corresponding number of unloading stations be used by companies that process several products delivered in flexible containers. The device needed only hang a simple pedestal on which it is discontinued. This simplified design of the unloading station allows a much more flexible use of the unloading station in that partial emptying and also the subsequent introduction of a large-volume container, with a much reduced handling and time is possible. After undocking the outlet nozzle z. As a forklift to take the device from the pedestal and a new settle on it.
  • The fact that 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. By automatically introducing the device in filling and discharging stations and by automatic docking of the filling of the filling these operations are semi-automated bez. can be fully automated. Also eliminated by the device time-consuming manual activities that were required to handle the bulky container in its conventional use, whereby a significant time savings is achieved. It has traditionally been a large-volume container either on a pallet, which in a separate operation under the large volume To bring container as a transport aid or brought to a carrying cross, which was attached to eg a forklift and to which the large-volume container was hooked manually to his usual four carrying straps, brought to the unloading station. Then the large-volume container had to be additionally manually relocated to the lifting device of the unloading station and lifted into it. The lifting device was also generally operated time consuming manually. In contrast, when using this device solely z. As a forklift required to move it from its storage place to z. B. to bring the emptying station. The introduction of filled large-volume container or their replacement for use in the same device is easier to handle and can be done in no time. The replacement of filled large-volume containers is possible by using the carrying strap design and in particular the self-locking holder. The problem with the introduction of partially or filled large-volume containers in the device is that the same strap is also required for hanging in the lifting device. Assuming that the large-volume container hangs on the hook of a carrying cross, the recording of the lifting mechanism can be brought only below the hook of the carrying cross in the same strap. When lowering the large-capacity container into the device, the lifting mechanisms are pressurized, so that when introduced large-volume container of the hook of the carrying cross in the carrying loop is clamped by the inclusion of the lifting mechanism. The hook of the carrying cross can only be removed under difficult conditions. The consideration of the execution of the large-volume containers, each with 2 carrying straps in each corner or by the central knotting each strap in two segments or the use of self-lashing strap loops always a loop or a loop segment remains free and free to move.
  • Trained as a pallet base plate can be modified so that this in their recording freedoms by suitable, commercial transport and handling equipment such. b. Forklift, automatic pallet stacking and unstacking, pallet truck, etc. is fully usable from all sides.
  • In a second embodiment of the device for large-volume containers at least four articulated arms are provided, which are connected to the lower end hingedly connected to the base plate of the closure mechanism, which is arranged on the bottom plate and which have at their outer and upper end in each case a fastening device with which the articulated arms can be connected to the four lower loops of the bulky container, so that the four articulated arms can support the funneling, which begins with the emptying of the bulky container, due to the lifting device, in which this in the emptying of the Swing large volume container upwards, so that the bottom of the large-volume container can be supported on this. Here, the articulated arms are interconnected by a central joint having a drive mechanism as a central transmission, which may consist of a gear transmission, a chain transmission, a linkage or a belt transmission or a hydraulic transmission. Alternatively, there is the possibility that the outer ends of the articulated arms may be provided with rollers, in which case the stanchions are designed as rails, the opening of the rails being directed inwards so that the rollers are arranged at the upper ends of the articulated arms are, can engage in the rails so that they are upwardly pivoting with the rollers in the rails are movable upwards. The rails can be formed either U-, V-, C- or H-shaped. The arms may also be telescopically formed, in which these consist of several individual segments which can be pushed into each other, so that the arms are adjustable in length. For fixation the segments are provided with a certain number of round, square or polygonal apertures, in which pins or clamps can be pushed as a holding and fixing means.
  • Instead of the articulated arms and the bottom plate itself may be articulated in which it is centrally provided with a continuous hinge or hinge, so that the bottom plate is divided into at least two segments which are pivotally mounted on the outer sides, wherein the outer Corners one or more roles may be arranged, which can then engage in the trained as rails stanchions. This may also be an attachment which can be placed on the actual base plate, which is designed as a pallet, which consists of segment parts and can be connected to the pallet.
  • In addition, the bottom plate may consist of individual differently shaped segments, which are hinged together, so that the bottom plate is arbitrarily malleable, and thus can also support the funneling, the bottom plate can be raised in a variety of places, to support the emptying of large-volume containers ,
  • In a third embodiment, the device for large-volume containers can be provided with a stencil-like attachment which can be releasably connected to the bottom plate by means of bolts, plugs, locks or the like and which can either be designed as a frame or can consist of only one plate or from an open-topped box, in which case the panel is provided on all four sides with walls which may be attached in pairs to the top or bottom of the panel so that the panel optionally acts as a floor or ceiling of the top. The essay may have different heights and the plate is designed as a frame so that it is also suitable for receiving container-like large-volume containers is, with the possibility that this frame-like plate is interchangeable with other frame-like plates, which depending on the shape and size of the large-volume container has a correspondingly adapted to this shape, which greatly simplifies the insertion of the large-volume container with its outlet nozzle in the closure system and which allows the use of the emptying device for all forms of large-volume containers. The attachment can either be made of metal or plastic or of wood and can have walls with different thicknesses. Each edge of the frame formed as a frame usually has a polygonal shape, which may be square or rectangular, but this may also have any other arbitrary shape. Alternatively, the article may be telescopically formed, in which the article composed of several telescopically expandable and telescoping wall parts, so that it is adjustable in height.
  • In a fourth embodiment it is provided that the stacking feet of the device for bulky containers are interchangeable in such a way that they can be exchanged for any length supports that can be arranged either extendable on the undersides of the stanchions, so that below the closure enough distance to the ground remains so that a wheelbarrow or the like can be pushed under the device for large-volume containers, for receiving the bulk material, which is to be filled from the large-volume container. These extendable legs or stilts, are connected by means of a lockable connection with the frame or the bottom plate of the device for large-volume containers, so that they are adjustable to any height. This also makes it possible that z. B. a pedestal, can be pushed under the device for large-volume containers, and can be connected to the underside of the closure, the z. B. contains a screw through which the emptying of the large-volume container can be accelerated, and by the a transfer of the bulk material in z. B. smaller containers is possible. This design is a versatile device for large-volume containers that can be connected in conjunction with any devices for emptying large-volume containers. This design also allows a modular design of the device for large-volume containers, so that they can be placed on other modules or integrated into these and can be detachably connected to these, which may be designed as a frame that trained as a pallet base plate of the device leader receiving, wherein both the recess of the bottom plate and the discharge opening with a correspondingly formed shaft, eg a conveyor zb a worm are aligned, whereby a rapid emptying is possible.
  • In a fifth embodiment it is provided that the closure of the emptying device can be connected to a hose or a tube through which an emptied large-volume container can be filled again with bulk material or similar flowable, dusty, powdery, granular or granular products by a the closure connected line can be injected or introduced into this. For this purpose, it is necessary that a vent must take place in the upper area, it being necessary that for this purpose the device for large-volume containers can be covered with a cover plate, which can be connected to the upper ends of the stanchions and can be placed on the lifting devices , And which has a central opening through which a vent is possible, which z. B. can be done by connecting another hose that can be connected to a vacuum pump or the like. In this opening a rubber, foam or styrofoam is arranged to seal.
  • In the cover plate can be arranged an opening in which a closure mechanism consisting of a closure for dosing, which is arranged in a base plate which is on the cover plate, which may also be roof-shaped, frustoconical or pyramid-shaped, attached, and is formed in that a hose or a pipe can be attached to it.
  • Alternatively, the closure may also be provided with a harness which z. B. may consist of chains or straps, with which this at the Aufhängestapelköpfen, which are arranged at the upper end of the stanchions, are attached.
  • Alternatively, for filling or emptying through the centrally arranged opening of the cover plate, a suction device can be guided into the large-volume container, which is a buoyant suction head connected to a suction tube or a suction tube with which the contents are sucked out of the container from above can be or can be injected into this, in which case the outlet pipe is closed at the bottom of the large-volume container through the closure, so that emptying or filling can be done from above.
  • In a sixth embodiment, the closure with the metered emptying of the bulky container is made possible by a central closure, which is composed of several, movable by the spring mechanism slats that release when opening an opening from the center and close again, the principle the closure in a tubular, flexible sleeve made of rubber or plastic fabrics, which opens or closes by 180 ° rotation centric similar to an iris diaphragm. The flow is released or closed in seconds, without a sealing cone, a wedge or plate must be pushed or screwed into the flow opening. The valve body and the rotating part are completely shielded by the closure sleeve against the continuous flowable material. This reduces mechanical stress to a minimum, prevents jamming or jamming, ensures absolute tightness even in the working area, and prevents material loss, soiled equipment and dust nuisance. This closure is also suitable for large-volume containers that are filled with viscous media from the coarsest to the finest embers and it is also suitable for air control during filling.
