Description

Technical field

The invention relates to a cutting device for unpacking bulk goods arranged in a bulk goods container. The invention also relates to a bulk goods container and a method for unpacking bulk goods.

State of the art

Bulk goods are typically arranged in bulk goods containers, for example to store and / or transport bulk goods. Bulk material can be firewood, for example, which is in the form of logs. The logs are typically geometrically processed in such a way that they can be burned by the end user, for example in a fireplace or a fireplace. Typical lengths of the logs are 25 to 50 cm. The log can have a rectangular, square or triangular cross section with a typical dimension of 5 to 15 cm. The bulk material, for example the logs, is typically packed using packaging machines. For example, packaging processes from Posch or Binderberger or Pezzolato are used here. The packaging machine typically has a stable container with side walls. The container can be, for example, a cylindrical barrel without a bottom and is made, for example, of a stable wall material, typically of structural steel. The container is typically placed on a pallet before the bulk material is placed in it. A typical container according to the prior art is in 14 shown. In the packaging process, the container is then lifted and at the same time a container cover is arranged around the bulk material below the container. The container casing typically encloses the bulk material in the vertical direction. The container casing can also enclose the bulk material in the horizontal direction, so that the bulk material is arranged on a sack-like container in this case. After the packaging process, the bulk material, for example the logs, is arranged in a bulk material container, which typically forms a network bundle. The bulk material is typically surrounded by a mesh or a film and kept in shape, the mesh forming the outer wall of the bulk material container. Depending on the packaging process, the network bundle is available as a cylindrical or cuboid network bundle.

The bulk material can be any material that is present in discrete bulk material elements. For example, the bulk material may have stones, pebbles, metal objects, plastic objects or objects made of another material.

The DE 24 44 303 A1 discloses a transport container for bulk goods, so-called bulk goods, in particular finely comminuted goods. The transport bag has an outer bag. Furthermore, the transport bag has a bottom with an opening.

In the utility model DE 82 33 454 U1 discloses a container, in particular a large-capacity sack, made of flexible material with an upper filling opening, a bottom part and a closure in the area of the bottom part which can be released with the release of an outlet opening.

In the DE 29 24 988 a container is disclosed. The container has an upper part and a base, the base and the upper part being connected to one another by an elongate element which is guided through the interior of the container and fastened to the base and the upper part.

The US 4,675,910 A shows a packaging for liquids and a method for producing such a packaging. The packaging is of the type of a sack, in particular a bulk container with an outer envelope. Within the outer envelope, a cord-like element is guided to a bottom part of the sack and is detachably connected to it.

Presentation of the invention, task, solution, advantages

It is the object of the invention to provide a device for unpacking bulk goods, a bulk goods container and a method for unpacking the bulk goods.

The object is achieved by a cutting device, a bulk goods container and a method for unpacking bulk goods with the features of the independent claims.

Advantageous embodiments of the cutting device and the method for unpacking bulk goods can be found in the dependent claims.

The cutting device according to the invention for unpacking bulk goods, which is arranged in a bulk goods container having a container casing, has at least one cutting device and at least one pulling element for fastening the cutting device to an external lifting device, the cutting device having at least one cutting edge for severing the container casing.

The container shell can have a wrapping fabric. The wrapping fabric can be a mesh, a film and / or a perforated film that is suitable for bulk material. The wrapping fabric can have side walls which essentially surround the bulk material in the vertical direction, for example side walls. The wrapping fabric

can also have a horizontal section, for example a floor. The horizontal section is typically connected to the side walls. The bulk goods container can have a sack-like shape.

The wrapping fabric can be severed by means of the cutting edge. In this case, the sheathing fabric forming the container casing can be severed along a line that is predetermined in particular by the movement of the cutting device. The bulk material can consist of wooden wedges, wooden blocks. The bulk material can also have elements of other materials, for example stone, sand, plastic, metal. The bulk material can have regularly shaped parts or irregularly shaped parts.

By connecting the cutting device to the at least one pulling element, the cutting device and the bulk material container can be moved simultaneously by means of the lifting device. Here, the movement of the cutting device can take place essentially vertically upwards. Here, the cutting edge can advantageously always automatically align optimally with the container casing to be separated. This makes it possible for the cutting device to be able to tear open the container casing during the lifting process. In addition, the movement of the bulk goods container can also take place essentially vertically upwards.

In one configuration of the cutting device it can be provided that the cutting device has a guide device for guiding the container casing or a partial section of the container casing in the direction of the cutting edge.

The wrapping fabric of the container casing and / or parts of the container casing can be guided in the direction of the cutting edge by means of the guide device. It is advantageous here that an uncontrolled movement of the container casing into areas outside the cutting edge can be prevented. It is no longer necessary for people, such as the unpacking workers, to manually guide a knife or scalpel along the container shell, as is used today. This avoids the risk of injury when unpacking. This enables safe unpacking, whereby the operating personnel can always be outside the danger zone.

Furthermore, the unpacking process can be carried out significantly faster, since at the same time the bulk goods container and the cutting device can be raised automatically by means of the lifting device. Typically, the cutting device can be guided on an outside of the bulk goods container. A device arranged or formed on a side facing away from the cutting edge, for example a rear side of the cutting device, can serve this purpose. This can be, for example, a shoulder formed on the cutting device on the rear side. If the cutting device has two or more cutting edges, one or two of the cutting edges can perform this function. The device, the back or the shoulder preferably form a bulk material fixing element.

In one configuration, the cutting device, in particular the cutting edge, can be moved along an outer edge and / or outer surface of the bulk material, but within the side walls of the bulk material container. The cutting device can move between the bulk material and the container casing. This effectively separates the container shell.

The fact that the cutting device can be guided automatically when the bulk goods container is lifted means that no worker has to be near the bulk goods container and there is no risk of injury when the bulk material falls apart. The unpacking process can also be done quickly. In particular, the unpacking process can be faster than when the container casing is cut open manually. Typical unpacking times of 10 seconds and less can be achieved.

The bulk goods container and thus the bulk goods are preferably arranged directly on a floor element, for example on a pallet element or a pallet. This is advantageous since the bottom element of the container casing with the bulk material can give stability. Furthermore, the container can only have side walls and does not have to have a bottom, wherein the bottom element can serve as a bottom. Advantageously, only the container shell has to be opened. The bulk material can be moved and transported from one place to another by means of the stable floor element. The unpacking can advantageously take place independently of the position. The bulk material can be unpacked on a surface, for example on the floor of a parking lot, a garage entrance or the like, or on a trailer. The Bulk goods can, for example, be transported to the customer and unpacked there.

The cutting device can also be used to open a bag-shaped bulk container. Here, the side walls and the bottom can be cut at least in sections with the cutting device.

It is also advantageous that the unpacking is independent of the geometry of the bulk goods container, since the cutting device can be guided along the container shell to be severed by means of the pulling element. The tension element is preferably arranged to be movable within the container shell. The cutting device can be arranged inside or outside the container casing. The cutting device can be guided outside the container shell during the lifting process. In one configuration of the cutting device, the cutting device can be arranged within the container shell. The cutting device can be designed as a separate element which can be connected to the tension element. In one configuration of the cutting device, the cutting device can be made in one piece with the tension element.

The cutting device is preferably simple. As a result, the cutting device is advantageously not susceptible to maintenance. It is also advantageous that all components of the cutting device, such as tension elements and cutting device, can be reused after use.

In one embodiment, the cutting edge has a straight course. This preferably gives a long cutting surface. The cutting edge can also be curved. A concave course can be provided here. In one configuration of the cutting device, the cutting device can have at least one abrasive section. In the embodiment, the cutting device can be made in one piece with the at least one tension element. The at least one traction device can be made in one piece or two pieces. The abrasive section of the tension element can be guided inside along the container shell during a lifting process. As a result, the wrapping fabric of the container shell can be destroyed and the container shell can be separated. It is advantageous here that the cutting device can be constructed more simply.

In one configuration of the cutting device, the guide device has a sliding edge, along which the container casing and thus the wrapping fabric or parts of the wrapping fabric can slide and thus be guided along. This is advantageous since the wrapping fabric and thus the container casing can be guided to the cutting device. As a result, a safe severing of the wrapping tissue can be ensured in particular.

The cutting device preferably also has a stop area in which the covering tissue can be stopped in its movement. In this way, a longer residence time of the wrapping fabric in the cutting area, and thus in the area of the cutting edge, can be ensured. Furthermore, the container casing can be prevented from reaching the area of the cutting edge. This is advantageous for a reliable cutting and severing of the wrapping tissue.

In one embodiment of the cutting device, a second tension element is provided in addition to the at least one tension element. The first and the second tension element are preferably arranged essentially offset by 180 degrees relative to the bulk material. As a result, the bulk goods container can be guided through the tension elements from two sides. In particular, during the vertical movement upwards, the container shell of the bulk goods container can be tightened on the side wall on which the second traction means is arranged. In this way, an opposite movement of the container casing can be initiated. Here, the upper edge of the side wall, on which the second traction means is arranged, can be shifted downwards, whereas on the side wall, on which the first traction element is arranged, the container shell can be shifted upwards, the cutting device being able to cut through the container shell at the same time. The tension on the container casing in the cutting area can be increased by the sliding movement. This has the advantage that the separation of the container casing can be done safely and reliably.

In a further embodiment of the cutting device, the first and / or the second tension element are arranged between the container casing and the bulk material arranged in the container casing. As a result, the first tension element and the second tension element can be arranged essentially vertically. The first and the second tension element are preferably held and / or fixed in the horizontal direction by the bulk material, in particular by bulk material elements of the bulk material and the container casing. Here, the first tension element and the second tension element are arranged so as to be displaceable in the vertical direction. As a result, when the first and / or the second tension element is subjected to a force, the first and / or the second tension element can be moved in the vertical direction. The first tension element can preferably be connected to the cutting device and this relative to the bulk material container, in particular relative to the Move the container casing. The second traction element can preferably be connected to other traction means and / or to the lifting device.

In one embodiment, the first and / or the second tension element can already be arranged in the bulk goods container during the packaging process. The first and / or the second tension element can preferably be arranged between the bulk material elements of the bulk material and the container casing. In this case, the cutting device can be provided separately and can be connected to the first pulling element in order to carry out an unpacking process.

In a preferred embodiment of the cutting device, a third tension element is provided, the second tension element and the third tension element being releasably connectable. In one configuration, the second and the third tension element can also be formed in one piece.

The first and the second and the third tension element preferably each have fastening means at a lower and an upper end. The fastening means can be designed as eyelets, loops or hooks. The fastening means can also be designed such that two tension elements can be connected to one another. Open hooks can be used here. The fastening means can also be designed in such a way that one or more pulling elements can be connected to the lifting device. For example, carabiner hooks can be used as connecting means to create a detachable connection.

In a further preferred embodiment of the cutting device, the third tension element has a stop element. By means of the stop element, the bulk material container can be moved upwards relative to the cutting device during the lifting process until the stop device strikes a fastening means arranged at the upper end of the second pulling element. Here, the fastening means is preferably a snap hook. This enables a gear ratio of 2 (cutting device) to 1 (floor element) to be achieved. This is advantageous since the container casing can be enclosed more and more tightly by the second and third pulling elements during the lifting process. As a result, the container casing to be cut by means of the cutting device can remain stable long enough and the wrapping tissue can be separated cleanly.

In a further embodiment of the cutting device, the third pulling element can be moved relative to the second pulling element, preferably essentially vertically.

In one configuration of the cutting device, the first, the second and / or the third pulling element each have fastening means at both ends. The fastening means are preferably designed in one piece with the tension elements. The fastening means can also be or are releasably connected to the respective traction elements, for example if they are used in the lifting process.

The object is also achieved by a method for unpacking bulk goods, which is arranged in a container shell formed by wrapping fabric. In the method, at least one traction means arranged between the container casing and the bulk material is connected to a cutting device according to the invention, in order to arrange the cutting device in relation to the container casing, to connect the traction means with a traction device and the wrapping fabric with the bulk material during one through the traction means and one to cut the external lifting device realized by means of the cutting device of the cutting device.

The method is preferably characterized in that, at the beginning of the lifting process, a base element on which the bulk material is arranged and the cutting device are moved vertically upward in a ratio of 1: 2.

In the method, at least one tension element can be arranged within the container shell, preferably between the container shell and the bulk material. In addition, a second tension element can be arranged in the container shell. The second tension element is preferably arranged between the bulk material and the container casing.

In an alternative embodiment, the first and / or the second pulling element can already be arranged in the bulk goods container at the start of the unpacking process. In this case, the first and / or the second traction element are arranged in the bulk goods container during a packing process of the bulk goods. This can be advantageous since the bulk material can be brought into the bulk material container simultaneously with the traction means in one work process. At the start of the unpacking process, there is then a bulk goods container with bulk goods arranged in the container shell and a first and / or a second traction means.

The advantage of the method is that the bulk material can be quickly separated from the container casing and the base element in one work step and at any location. The handling of the method is advantageously simple, since only fastening means of the tension elements must be connected to each other and / or with a lifting device. During the unpacking process, in which the container casing is cut, the operating personnel can be outside the danger zone. The method can be used for bulk containers with any geometry.

The object is further achieved in that a bulk material container is provided which has a container shell and bulk material with bulk material elements arranged inside the container shell, at least one tension element being arranged between the container shell and the bulk material. The at least one tension element is preferably a first tension element which can be connected to the cutting device. A second tension element can be arranged inside the container shell. The second tension element can be connected to a third tension element arranged outside the container casing. The first traction element and the third traction element can be connected to a lifting device before the unpacking process begins.

The first and the second tension element are preferably arranged essentially offset by 180 degrees.

It is advantageous here that the bulk goods container can be easily connected to a lifting device, just as the first pulling element can be connected to the lifting device, for example by a releasable connecting element.

In one configuration of the bulk goods container, it can also be provided that the at least one tension element is arranged at least in sections within the container shell, for example is woven with it. This enables a stable arrangement to be achieved. The connection of the traction means to the container casing can be advantageous since it prevents the traction means from getting caught in the bulk material.

The invention also includes a packaging device that has a container, the container having fastening elements. The fastening elements are preferably arranged on an upper region of the container. Bulk material elements can be placed in the container during the packaging process. In addition, tension elements can be arranged on the fastening means of the container. The tension elements are preferably arranged between the bulk material elements and a container wall. During the packaging process, the tension elements can be arranged between the container casing and the bulk material. At the end of the packaging process, there is a bulk goods container according to the invention with bulk goods and at least one traction element.

Features and advantages that have been described in connection with the cutting device can also be applied to the method and apply to the method without being explicitly described.
