Description

[0001] The invention relates to a conveyor system for conveying goods, as well as a method for operating a conveyor system.

[0002] Conveyor systems are typically used for transporting materials such as bulk goods, rock, or sand from an open-pit mine. For conveying materials over steep inclines or when transporting hazardous materials, hose conveyors are used, where the conveyor belt is formed into a tube and encloses the conveyed material.

[0003] German patent DE 40 28 469 A1 discloses a feeding device for feeding material onto a conveyor belt, wherein the conveyor belt is formed into a conveying tube after being filled. The conveyor belt is pre-tensioned in such a way that, after the U-shaped opening of the conveyor belt, it automatically forms itself into a conveying tube. The material is fed in via a hopper from the upward-facing open end of the U-shaped conveyor belt, and then the conveyor belt is completely closed to form a conveying tube.

[0004] One problem with feeding material onto a conveyor belt that is formed into a conveying tube is that the conveyed material contains both small and large particles. The large particles must be handled appropriately so that the conveyor belt can be formed into a conveying tube without collisions between the belt and the large particles. Large particles can be elongated, especially if they have been processed with a gyratory crusher. These so-called "fish" are elongated large particles that, along a main longitudinal axis, can have dimensions larger than the diameter of the formed conveying tube.

[0005] Furthermore, large pieces of material place considerable stress on the conveyor belt and its guides, potentially even causing damage if they come into direct contact with the belt. Minimizing this stress on the conveyor belt is therefore desirable.

[0006] Based on this, the object of the present invention is to provide a conveying device designed in such a way as to prevent high loads on the conveyor belt and the belt guide device and to minimize damage.

[0007] This problem is solved according to the invention by a conveyor belt system with the features of independent apparatus claims 1 and 2 and independent method claims 9 and 10. Advantageous further developments are described in the dependent claims.

[0008] A conveying system for transporting goods comprises, according to a first aspect, a conveyor belt, a feed device for feeding goods onto the conveyor belt, and a belt system in which the conveyor belt is guided. The belt system includes a belt forming device with which the conveyor belt can be shaped into a U-shape up to the feed device, so that the goods can be fed into the U-shape. The belt forming device also allows the conveyor belt to be formed into a closed tube in the conveying direction behind the feed device. The feed device has a collection area designed such that the goods accumulate in it and form an impact surface onto which the goods can be fed.

[0009] The conveyor system preferably comprises a plurality of belt forming devices arranged one behind the other in the conveying direction, which are designed such that the conveyor belt guided therein can first be formed into a U-shape and then into a closed tube by means of the belt forming device. In particular, each belt forming device has at least three rollers which are arranged relative to each other such that the conveyor belt guided thereon has a U-shape or a tube shape.

[0010] The feed device is preferably stationary and arranged above the conveyor belt, so that the conveyed material can be fed onto the U-shaped conveyor belt by means of the feed device. In the area behind the feed device in the conveying direction, the conveyor belt has at least a partially closed, tubular shape, with the conveyed material arranged within the tubular conveyor belt and, in particular, completely enclosed by it.

[0011] The conveyed material is fed into the feed device, for example, by a conveying unit located above the conveyor belt using a conveyor belt. For this purpose, the stationary feed device is positioned below the discharge end of the conveyor belt such that the conveyed material falls from the conveyor belt into the feed device. The conveyor belt is, for example, a substantially flat belt guided by pulleys, on which the conveyed material rests.

[0012] The feed device is, for example, a chute with a collection area designed to allow conveyed material to accumulate and form an impact surface onto which it can be fed. The impact surface is preferably located below the discharge end of the conveyor belt, above the conveyor belt, so that conveyed material falls from the discharge end onto the impact surface. The collection area is arranged in the feed device such that conveyed material falling into the feed device from above enters the collection area and accumulates there. The conveyed material accumulates in the collection area and forms an impact surface that can be subjected to further conveyed material. The feed device extends, in particular, in the conveying direction of the conveyor belt and has, for example, a box-shaped upper section with a rectangular cross-section.Preferably, a side of the box-shaped area extending in the conveying direction of the conveyor belt forms the collection area. An opening is arranged in the box-shaped area, to which preferably at least two vertical wall elements are connected, pointing in the direction of the conveyor belt. The feed device has, for example, a plurality of collection areas, which are arranged in such a way that the conveyed material accumulating in the collection areas forms an impact surface. The impact surface is preferably essentially flat.

[0013] According to an unexpected discovery by the inventors, an impact surface formed by material deposited in the collection device enables optimal pre-orientation of the conveyed material, particularly elongated pieces of material (fish). This supports the alignment of the elongated material pieces in the U-shaped belt in the direction of the conveyor belt and reduces the risk of material pieces lying perpendicular to the conveying direction of the conveyor belt. Elongated material pieces are understood to be, in particular, those pieces that have a length exceeding the diameter of the closed, tubular conveyor belt and could therefore cause damage to the conveyor belt.When the elongated material chunks hit the conveyor belt, they are aligned in the conveying direction by the belt's speed, thus reliably reducing damage to the conveyor belt caused by material chunks lying perpendicular to the conveying direction. This type of feed device has proven particularly advantageous for filling a conveyor belt that is subsequently formed into a tube. Furthermore, the impact surface formed by the material deposited in the collection device ensures that the conveyed material is deagglomerated, with the material being distributed across the impact surface upon contact.Furthermore, such an impact surface significantly reduces the wear of the feed device, since after deposition of the conveyed material, the conveyed material passing through the feed device preferably does not have direct contact with the side walls and / or the bottom of the feed device.

[0014] A conveying system for conveying goods comprises, according to a further aspect, a conveyor belt, a feed device for feeding goods onto the conveyor belt, and a belt system in which the conveyor belt is guided. The belt system includes a belt forming device with which the conveyor belt can be formed into a U-shape up to the feed device, so that the goods can be fed into the U-shape. The belt forming device allows the conveyor belt to be formed into a closed tube in the conveying direction behind the feed device. The feed device has an impact surface oriented at an angle of approximately 30°–60°, in particular 40°–50°, preferably approximately 45°, to the horizontal. Such an impact surface is, for example, a metal plate, in particular steel, and the impact surface is preferably substantially flat.

[0015] Such an impact surface also allows for the pre-orientation of the conveyed material, especially elongated material fragments (fish). This supports the alignment of the elongated material fragments in the U-shaped belt in the direction of the conveyor belt, thereby reducing the risk of material fragments lying perpendicular to the conveying direction of the conveyor belt. An orientation of the impact surface at an angle of approximately 30°–60°, particularly 40°–50°, preferably approximately 45° to the horizontal, has proven particularly advantageous for aligning the material fragments sliding on the impact surface in the direction of the conveyor belt, ensuring optimal alignment.

[0016] According to a first embodiment, the impact surface extends in the conveying direction of the conveyor belt. Preferably, the edge of the impact surface facing the conveyor belt extends parallel to the conveying direction of the conveyor belt. In particular, the feed device, preferably the collection area of ​​the feed device, extends in the conveying direction of the conveyor belt. The impact surface has an angle of inclination to the horizontal of 30°–60°, preferably 40°–50°, most preferably 45°, and runs above the conveyor belt essentially parallel to it. This enables optimal pre-orientation of the conveyed material according to the plane of the impact surface. In particular, the projection of the fall line of the material moving along the impact surface is approximately perpendicular to the extent of the conveyor belt.

[0017] According to a further embodiment, the feeding device comprises a chute, wherein the impact surface is arranged in the chute. A chute is understood to be a means for the directed transport of the conveyed material by means of gravity. For example, a chute comprises a slide, a hopper, a downpipe, or a funnel.

[0018] According to a further embodiment, the impact surface is arranged at an angle towards the conveyor belt, so that the conveyed material is directed from the impact surface, in particular directly, onto the conveyor belt. Following the impact surface, the conveyed material is guided, for example, directly into the U-shaped section of the conveyor belt. Preferably, no further elements are arranged between the impact surface and the conveyor belt.

[0019] In a further embodiment, a guide element is arranged between the impact surface and the conveyor belt, so that the conveyed material is guided from the impact surface onto the guide element. The guide element is, for example, plate-shaped and attached to the conveyor-side end of the impact surface. From the guide element, the conveyed material passes, preferably directly, onto the conveyor belt.

[0020] According to a further embodiment, the guide element is designed such that conveyed material sliding along it is aligned and preferably deflected in the conveying direction of the conveyor belt. The guide element preferably has guide vanes or protrusions that align the conveyed material in the conveying direction of the conveyor belt. For example, the guide vanes or protrusions essentially describe a partial circle shape, preferably a quarter circle shape. Such a guide element reduces the relative velocity of the conveyor belt and the conveyed material when the material impacts the conveyor belt. This reduces wear and stress on the conveyor belt.

[0021] According to a further embodiment, the guide element has an angle of inclination that corresponds approximately to the angle of inclination of the impact surface. In particular, the guide element forms an extension of the impact surface, thereby optimizing the pre-orientation of the conveyed material. Specifically, the guide element is oriented essentially parallel to the impact surface.

[0022] In particular, the impact surface is formed from a wear-resistant bed material.

[0023] The invention further comprises a method for operating a conveyor system for conveying goods, wherein the conveyor system includes a conveyor belt, a feed device for feeding goods onto the conveyor belt, and a belt system in which the conveyor belt is guided, with a belt forming device for shaping the conveyor belt, wherein the conveyor belt is formed into a U-shape up to the feed device and, in the conveying direction, behind the feed device, into a closed tube. The conveyed goods fall into a collection area of ​​the feed device, accumulate in the collection area, and form an impact surface onto which further conveyed goods are fed.

[0024] The invention further comprises a method for operating a conveyor system for conveying goods, wherein the conveyor system includes a conveyor belt, a feed device for feeding goods onto the conveyor belt, and a belt guide in which the conveyor belt is guided, with a belt forming device for shaping the conveyor belt, wherein the conveyor belt is formed into a U-shape up to the feed device and, in the conveying direction, behind the feed device, into a closed tube. The conveyed goods fall onto an impact surface arranged in the feed device, wherein the impact surface has an angle of approximately 30°–60°, in particular 40°–50°, preferably approximately 45°, to the horizontal.

[0025] According to one embodiment, the conveyed material slides over the impact surface and is aligned in the conveying direction of the conveyor belt upon impact.

[0026] The advantages described with regard to the conveyor system apply in a procedurally equivalent manner to the procedure for operating a conveyor system. Description of the drawings
