The pocket conveyor belt (1) is characterized by at least one planar element (2), which is arranged at least substantially transversely to the direction of movement (A) of the pocket conveyor belt (1) on a first side (17) of the conveyor belt body (1) which supports the inside (FIG. 17) of the closed pocket conveyor belt (1), wherein the planar element (2) is at least partially, preferably completely, unconnected to the first side (17) of the conveyor belt body (1).)

Description

The present invention relates to a pocket conveyor belt according to the preamble of claim 1 and a pocket conveyor belt system with such a pocket conveyor belt according to claim 11.

In the field of conveyor technology, a conveyor belt type called SICON ^{® is} known, which, for example, in the EP 0 286 637 B1 is described. A SICON conveyor belt has in the longitudinal direction, ie in the direction of movement of the conveyor belt, two steel cables as tension members, which are vulcanized in each case in the two edge regions in the transverse direction. The area in the transverse direction between the two steel cables is free of tension members. The two edge regions furthermore have profiles around the steel cables which can be guided substantially in common by corresponding guide rollers, so that the conveyor belt can be suspended downwards.

In this way, a SICON conveyor belt can be folded like a bag for the closed transport of loose conveyed, so that the two edge regions can be performed lying one above the other. The intermediate surface of the SICON conveyor belt hangs freely down and carries the conveyed closed. A SICON conveyor belt can therefore also be referred to as a pocket conveyor belt or pocket conveyor. By means of appropriate guides, the SICON conveyor belt can be opened and closed at the loading and unloading points.

An advantage of SICON conveyor belts is that the SICON conveyor belt or the corresponding conveyor belt system requires little space and can therefore be used in tight situations. This also applies to overcoming height differences in tight situations. In this case, height differences can usually be overcome with pocket-shaped closed SICON conveyor belt with gradients up to about 35 ° by the conveyed can be compressed inside the bag or the bag and thereby held non-positively.

A disadvantage of SICON conveyor belts, however, is that with flowable goods such. Cement due to the relatively low positive connection between the goods and the inside of the SICON conveyor belt only gradients up to about 10 ° can be realized. Another disadvantage is that with SICON conveyor belts no vertical, i. vertical, conveyor belt systems can be realized.

To overcome these disadvantages for a SICON conveyor belt, very long conveyor lines would be required, but this can lead to correspondingly high investment and operating costs. Furthermore, this space is required in order to set up the appropriate conveyor belt system. However, this space can not exist at all, so that the SICON conveyor belt can not be used to overcome larger gradients. This can prevent the use of the beneficial properties of a SICON belt for many applications.

For the promotion of loose conveyed at high gradients up to vertical promotion various conveyor belts or conveyor belt systems are known which have flat elements which protrude perpendicular to the conveying direction perpendicularly from the support side of the conveyor belt to the conveyed at regular intervals in the conveying direction as a holding surface hold. Such flat elements are usually vulcanized onto the support side of the conveyor belt. It can be provided individual flat elements or a plurality of sheet-like elements which move in the rolled-up, collapsed or in the troughed state of the conveyor belt to each other in the transverse direction and thereby form a common or complementary holding surface, which the conveyed positively in the direction of movement or Can keep delivery direction. Examples are the DE 1 014 024 A , of the DE 958 549 B , of the CH 647 737 A5 , of the FR 2 469 365 A , of the FR 810.482 B , of the GB 444,549 B , of the JP S 64-87416 A and the JP S 57-151 509 A refer to.

A disadvantage of these solutions that the sheet-like elements are always arranged on the support side of the respective conveyor belt. This is usually done by vulcanization, so that only a destructively separable connection between the flat elements and the support side of the conveyor belt is made. This can lead to the fact that the entire conveyor belt must be repaired or replaced in case of wear and / or damage to the sheet-like elements. Furthermore, fixed planar elements are usually created at least in the transverse direction in sections, which can have a restrictive effect on the flexibility of the conveyor belt.

Conversely, the stretching of the conveyor belt during operation and in particular in curves, especially in tight curves, lead to loads on the flat elements, so that the connection between the flat elements and the support side of the conveyor belt can be damaged or canceled. This can lead to the release of the flat elements during operation, so that the conveyed goods can no longer be held and may slip or fall. This conveyed material can tear further flat elements with it, so that it can lead to a rupture of the closed conveyor belt or overflowing a troughed conveyor belt through the conveyed. As a result, the entire conveyor belt system can be damaged and shut down. This can also endanger the environment and people.

An object of the present invention is to provide a pocket conveyor belt and / or a pocket conveyor belt system of the type described above, so that the conveyed material can be conveyed with larger gradients and / or vertically. This should be made possible in particular with the least possible effort and / or with the least possible additional space. At least an alternative to known possibilities should be created.

The object is achieved by a Taschenfördergurt with the features of claim 1 and a Taschenfördergurtanlage with the features of claim 11. Advantageous developments are described in the subclaims.

The present invention thus relates to a pocket conveyor belt with a conveyor belt body, which is designed to receive a conveyed material in the interior of the closed pocket conveyor belt. The conveyor belt body may preferably comprise an elastomeric material or consist of an elastomeric material. The material to be conveyed may preferably be a bulk material and particularly preferably a flowable material such as e.g. Be cement.

The pocket conveyor belt according to the invention is characterized by at least one planar element which is arranged at least substantially transversely to the direction of movement of the pocket conveyor belt on a first side of the conveyor belt body, which is the inside of the closed pocket conveyor belt.

In other words, at least one planar element is provided, which protrudes perpendicularly from the inside of the closed pocket conveyor belt to the conveyed out and thus can hold the conveyed positively, in particular when the direction of movement of the pocket conveyor belt deviates from the horizontal plane. In this way, the conveyed at larger gradients than previously known and depending on the extent of the sheet-like element even transported in the vertical direction.

Also, this can be spared in general, even at lower gradients the conveyed, because the forces can be reduced within the conveyed material by the positive retention of the conveyed material by means of the sheet-like element. As a result, a material-friendlier promotion can be achieved than in known bag conveyor belts.

In order to enable this positive transport of the conveyor belt in a pocket conveyor belt, the planar element is at least partially unconnected to the first side of the conveyor belt body. In this way, the pocket conveyor belt for loading and unloading at the task or delivery point can be at least partially opened to the full extent and spread in the transverse direction surface. This would interfere with a firm connection between a sheet-like element and the first side of the pocket conveyor belt, because they could tear during opening or greatly restrict the opening.

Thus, according to the invention, the planar element is at least partially not connected to the first side of the pocket conveyor belt to allow in this area a relative movement between the edge of the sheet member and the first side of the pocket conveyor belt. Furthermore, the flexibility and the ability to curve of a pocket conveyor belt can thus be maintained even with inventive expansion of the flat element, so that the application possibilities of a pocket conveyor belt only expanded or its properties are only improved without limiting the previous applications or to change the properties or even to worsen.

According to one aspect of the present invention, the planar element has a first flat half-element which is connected with a first connection to a first conveyor belt edge of the pocket conveyor belt, and a second planar holding element which is connected with a second connection to a second conveyor belt edge of the pocket conveyor belt. The connections can be cohesive, positive and / or non-positive. For this rivet and / or adhesive or vulcanization can be used. Preferably, the connections are made by means of detachable screw connections in order to easily replace the flat half elements in case of damage or destruction can.

Provide the connections to the Fördergurtkanten is advantageous because a stable connection between the Taschenfördergurt and the two flat half-elements can be provided without a connection between the two planar half elements to the conveyor belt body is present. As a result, the flexibility and the curve of the pocket belt can be maintained.

According to a further aspect of the present invention, the first planar half element and / or the second planar holding element is or are completely unconnected to the inside of the conveyor belt body in the transverse direction. In this way, the flexibility and the Kurvengängigkeit a pocket conveyor belt can be maintained as previously known.

According to a further aspect of the present invention, the first planar half-element and the second planar holding element are connected to each other by means of a rotating mechanism about a rotation axis rotatable with each other, wherein the axis of rotation at least substantially corresponds to the direction of movement of the pocket conveyor belt. In this way, the two flat half-elements can be designed to be movable relative to each other and arranged so that the two flat half-elements can rotate against each other both during opening and closing of the pocket conveyor belt and during operation of the closed pocket conveyor belt.

According to a further aspect of the present invention, the rotating mechanism is arranged in each case at the end of the planar half-element, which lies opposite the respective connection perpendicular to the direction of movement. In this way, the rotation mechanism can be spaced as far as possible to the connections, which constitute a fixed connection of the respective flat Halbelements to Taschenfördergurt or to the Fördergurtkanten.

According to a further aspect of the present invention, the first conveyor belt edge and / or the second conveyor belt edge is / are reinforced, preferably fabric-reinforced. In this way, the stability of the conveyor belt edge or conveyor belt edges can be increased. In particular, the tear strength can be increased. This can increase the life. For this purpose, in particular tissues are suitable, which are e.g. in the conveyor belt edges, which comprise an elastomeric material or consist of an elastomeric material, may be embedded in the material.

According to a further aspect of the present invention, the shape of the planar element or of the two planar half elements at least substantially corresponds to the shape of the interior of the closed pocket conveyor belt perpendicular to the direction of movement. In this way, the most complete possible completion of the interior in the closed state of the bag conveyor belt by the sheet-like element or the two flat half-elements can be achieved together, whereby the positive fit of the conveyed material can be achieved or maximized.

According to a further aspect of the present invention, the planar element or the first planar half-element and / or the second planar half-element comprises an elastomeric material, preferably consists of an elastomeric material. By using an elastomeric material, e.g. Rubber, the sheet-like element or the flat retaining elements can be made simple, flexible in the design and cost.

According to a further aspect of the present invention, the planar element or the first planar half element and / or the second planar half element is or are reinforced, preferably fabric-reinforced. As a result, the durability and thus life of the sheet-like element or the flat half-elements can be increased. Furthermore, especially with high to vertical gradients of the positive fit of the conveyed material can be improved because the reinforced sheet-like element or the reinforced sheet-like elements better the weight of the conveyed, i. with less to no deflection, can hold.

To use a tissue-based reinforcement for this purpose may be advantageous, especially in the case of a planar element or in the case of flat half-elements of an elastomeric material, because the tissue can be embedded in the material.

According to a further aspect of the present invention, the pocket conveyor belt further comprises a plurality of planar elements, which are arranged spaced apart in the direction of movement of the pocket conveyor belt. In this way, the load to be supported of the conveyed material can be distributed over a plurality of flat elements, so that the individual sheet-like elements can be relieved. This is all the more noticeable, the greater the slope is.

In this case, the sheet-like elements can be arranged equidistant or differently spaced from each other. Preferably, the flat elements are equidistantly spaced from each other to distribute the loads as evenly as possible.

The present invention also relates to a pocket conveyor belt system with a pocket conveyor belt as previously described. In this way, the characteristics and advantages of the Bag conveyor belt according to the invention are used in a corresponding Fördergurtanlage.

The pocket conveyor belt 1 For example, a SICON conveyor belt 1 be. The pocket conveyor belt 1 extends in the representations of 1 . 2 and 5 in a longitudinal direction X, which may also be referred to as length X. The pocket conveyor belt 1 can be moved in the longitudinal direction X, so that the movement direction A and the conveying direction A in the longitudinal direction X shows. Perpendicular to the longitudinal direction X or to each other extend the transverse direction Y, which may also be referred to as width Y, and the vertical direction Z, which may also be referred to as height Z.

The pocket conveyor belt 1 has a conveyor belt body 10 which consists essentially of rubber as an elastomeric material and also as a bag 10 or bag 10 can be designated. The conveyor belt body 10 is designed to be flexible as possible to allow it to open and close and in the closed state, the conveyed material (not shown) held in pocket-shaped hold and transport.

The pocket conveyor belt 1 also has a first conveyor belt edge 11 and a second conveyor belt edge 12 on, each consisting of rubber as elastomeric material and having a vulcanized tissue as reinforcement. The conveyor belt edges 11 . 12 each have a profile 13 on, which are aligned on the same side and arranged one above the other by the guide rollers of a conveyor belt system can be held (not shown), so that the pocket shape of the closed Taschenfördergurtes 1 formed. Within the profiles 13 the conveyor belt edges 11 . 12 is in each case an extending in the longitudinal direction X and endlessly closed in this direction tension member 14 in the form of a steel rope 14 embedded.

The two conveyor belt edges 11 . 12 each further have a first contact area 15 or a second contact area 16 on, in each case cohesively by vulcanization with the pointing in the transverse direction Y edge of the open and horizontally horizontally spread Fördergurtkörpers 10 are connected. The upper side of the open and horizontally horizontally spread conveyor belt body 10 will be the first page 17 of the conveyor belt body 10 designated or as inside 17 the closed bag conveyor belt 1 , The first page 17 of the conveyor belt body 10 also represents the support side 17 of the pocket conveyor belt 1 In the closed state, the pocket conveyor belt closes 1 with its inside 17 an interior 18 in, in which the conveyed goods can be transported.

Such bag conveyor belts 1 are known and have, inter alia, the disadvantage that the conveyed during transport with incline in the direction of movement A can slip.

To avoid this, the pocket conveyor belt according to the invention has 1 a plurality of planar elements 2 on which transverse to the direction of movement A at regular intervals C to each other in the interior 18 the closed bag conveyor belt 1 are arranged. In this way, the conveyed can be kept in sections, so that slipping over the respective sheet-like element 2 can be avoided.

Every flat element 2 has a first planar half-element 20 and a second planar half-element 21 on, which each as about half-drip-shaped elastomer plates 20 . 21 are formed. The two flat half elements 20 . 21 are arranged so that they can overlap each other and in the closed state of the bag conveyor belt 1 its interior 18 preferably completely in the plane perpendicular to the direction of A fill.

The two flat half elements 20 . 21 are each by means of a connection 24 . 25 in the form of screw detachable with the respective contact area 15 . 16 the conveyor belt edges 11 . 12 connected. The edges 23 the two flat half elements 20 . 21 that's the first page 17 of the conveyor belt body 10 facing, are with the conveyor belt body 10 unconnected, leaving the two flat half-elements 20 . 21 only over the two contact area 15 . 16 with the remaining pocket conveyor belt 1 connected and otherwise to the conveyor belt body 10 are mobile. This allows a stable connection without the flexibility and flexibility of the pocket conveyor belt 1 to impair.

At their the connections 24 . 25 opposite ends have the two flat half-elements 20 . 21 a rotating mechanism 23 in the form of a screw connection 23 on, over which the two flat half elements 20 . 21 against each other about a rotation axis B are rotatable. In this way, the two flat half-elements 20 . 21 be connected to each other and at the same time continue to open and close the Taschenfördergurtes 1 the contour of the conveyor belt body 10 to adjust.
