Definitions
- the invention relates to a scraper system for a conveyor system with a conveyor belt, a module carrier for such a scraper system and a method for attaching a scraper module to a scraper system.
- scraper systems are known for conveyor belts that are used to convey a wide variety of conveyed goods. By placing a stripping element on the running conveyor belt, any material adhering to it is stripped off.
- wiper systems have a plurality of wiper modules with wiper elements and a system carrier which extends transversely to the running direction of the conveyor belt.
- DE 102017114931 Ai shows a scraper system for arrangement in the deflection area formed by a discharge drum of high-speed belt conveyor belts.
- On a transversely to the running direction of the belt conveyor and resiliently stored th system carrier stripping blocks made of elastic material are attached next to each other in an interchangeable manner.
- DE 10 2013 006 821 Ai describes a belt scraper system made up of modules for the return area of conveyor belts.
- a system carrier is arranged transversely to the direction of travel of the conveyor belt.
- Several stripping modules are attached next to each other on the system carrier.
- the stripping modules each carry a stripping lamella, which rests against the belt in a peeling manner.
- EP o 270142 Bi describes a scraper for a conveyor belt with a number of scraper elements, each having scraper blades and arranged next to one another on an elongated carrier which extends transversely to the longitudinal direction of the conveyor belt and is attached to the frame of the belt conveyor in such a way that the stripping elements are pressed with the free edges against the underside of the conveyor belt.
- the Abstreifele elements are divided into two groups and arranged on two rod-shaped rod elements with a U-shaped cross section.
- the rod elements are arranged on a carrier with a rectangular cross-section. At the end they have openings into which protruding pins of the carrier engage. At the opposite end, the elements have flanges to which they are fastened with bolts using screw connections.
- US 2015/0360880 Ai relates to a stripping device for a conveyor belt with a removable stripper assembly that can be easily connected to and removed from an elongated carrier.
- the assembly includes Abstreiferklin conditions that are attached to an angle brace.
- a pair of clamps is used as a securing mechanism, with which the angle brace is clamped to receptacles on the carrier.
- the US 3342312 discloses a stripping device for a conveyor belt with a plurality of individual wiper blade assemblies.
- a tube is net angeord across the conveyor belt.
- a holder with an L-shaped cross-section is attached to the pipe so that it can be rotated and displaced by means of C-clamps.
- the object is achieved according to a first aspect by a wiper system according to claim 1 and a method for attaching a wiper module according to claim 12.
- the object is achieved by a wiper System according to claim 13 and a module carrier segment therefor according to claim 14.
- Dependent claims relate to advantageous embodiments of the invention.
- the inventors started from the idea that maintenance work on the scraper system and in particular the replacement of wear parts are particularly time-consuming when dangerous areas of the plant have to be entered and therefore safety measures such as the installation of scaffolding or the like as well as longer interruptions to operations are necessary . It would therefore be of particular interest to be able to carry out maintenance work on scraper modules from outside the belt area, ideally without having to carry out work inside the chute or below the belt conveyor.
- the inventors therefore propose an easily exchangeable attachment for scraper modules, which enables the scraper modules to be changed in a simplified manner, whereby staying in the area below the belt conveyor can be minimized or even avoided entirely.
- the scraper system comprises a system carrier which preferably extends transversely to the running direction of the conveyor belt.
- the system carrier can, for example, as a rod or tube with z. B. round or rectangular cross-section. It is preferably attached in a stationary manner on both sides, for example on the belt frame.
- the system carrier can be fixed or, alternatively, movably arranged, in particular spring-loaded.
- the wiper system according to the invention also has a plurality of wiper modules. These are intended to rest on the conveyor belt and preferably have a stripping element for this purpose, which can be, for example, an edge, lamella, a stripping block or some other type of stripping element.
- the scraper modules can be differenttapped det depending on the type and arrangement of the scraper system relative to the conveyor belt.
- the wiper modules can have one or more elements that can move relative to one another and joints, springs, etc. arranged between them.
- the wiper modules can also be, for example, block elements, preferably made of a flexible material.
- the wiper modules are attached to a module carrier which extends on the system carrier parallel to the latter and is detachable there is appropriate.
- a clamping arrangement is provided according to the invention which applies a clamping force which acts in the transverse direction to the system carrier.
- the clamping arrangement comprises a clamping rod which extends parallel to the system carrier and with which the clamping force is applied before given by a wedge effect.
- the clamping force can also be generated by other measures, for example by spring action, for example by means of one or more spring clips or by a pressure medium, for example hydraulically or pneumatically, for example by one or more pressure cylinders, pressure pads or the like.
- the wiper system according to the invention is thus characterized in accordance with the first aspect of the invention by the system carrier, the module carrier and the clamping rod as three elements which are aligned in parallel and are preferably elongated.
- these three elements extend at least substantially over the entire width of the conveyor belt, which can enable handling from the side without having to enter the area below the conveyor belt.
- the module carrier is attached to the system carrier by means of a Klemmwir effect in which the clamping force or at least one component thereof acts in the transverse direction of the system carrier.
- the clamping creates an at least frictional connection of the module carrier to the system carrier, so that the module carrier preferably remains firmly on the system carrier and the forces occurring during operation of the scraper system through the contact of the scraper modules with the conveyor belt can be absorbed.
- the attachment of the module carrier to the system carrier can optionally be supported by a form-fitting receptacle, but a purely frictional connection can be preferred for better detachability of the connection from the side.
- the clamping force can act at at least one point on the system carrier and module carrier, before it acts over the entire length of the module carrier and / or system carrier or at least at a number of clamping points spaced apart in the longitudinal direction of the system carrier. In this way a consistently durable connection can be achieved.
- the clamping force is preferably applied by wedge action, ie by acting on the clamping rod in a first direction, which can be referred to as the wedge or insertion direction, to generate the clamping force in a different direction second direction, which can be referred to as the clamping direction and is oriented transversely to the system carrier.
- the wedge direction can, for example, be oriented parallel to the longitudinal direction of the system carrier, preferably it is oriented transversely thereto.
- the wedge effect can emanate from a wedge shape of the clamping rod or from one or more wedge elements arranged on the clamping rod; in addition or as an alternative to this, the wedge effect can also be brought about by separate wedge elements or wedge surfaces which, for example, can be attached to the system carrier in a stationary manner.
- Such a scraper system with scraper modules on a module carrier and a clamp arrangement held by means of a clamp rod, preferably by wedge effect, proves to be extremely advantageous because a durable connection of the stripper modules to the system carrier can be achieved with a connection that is easy to make and just as easy to detach .
- the wiper system can be designed in such a way that access only from the side, preferably only from one side, can be sufficient for establishing and / or releasing the connection.
- the clamping force can be applied by at least one pair of surfaces, at least one of the surfaces involved being a wedge surface.
- One of the surfaces involved in the pairing of surfaces can be provided on the clamping rod, the other is preferably fixed to the system carrier.
- the wedge surface may have an inclination of, for example, i -. 45 have 0, preferably 8 - 30 °, more preferably 12-20 ° with respect to the insertion direction, wherein the curve need not be linear, but changing inclination and curves are possible. It is also possible for both surfaces of the surface pairing to be wedge surfaces.
- At least one holding element can be arranged on the system carrier and the clamping rod can be arranged between the module carrier and the holding element.
- a plurality of holding elements spaced apart in the longitudinal direction of the system carrier are preferably provided.
- the holding elements are preferably fixed directly or indirectly to the system carrier, for example by means of a screw connection.
- the holding elements can, for example, protrude in a direction transverse to the system carrier and thus form counter bearings for the clamping arrangement.
- At least one counter-holding element can be arranged on the system carrier at a distance from the Hal teelement, so that the module carrier and the clamping rod are arranged between the holding element and the counter-holding element.
- a plurality of counter-holding elements spaced apart in the longitudinal direction of the system carrier are preferably provided, particularly preferably in pairs with corresponding holding elements. Holding and counter holding elements can, for example, form a clamp in which the clamping rod and module carrier are clamped.
- the clamping rod can be acted upon by a connecting arrangement with a clamping force in the direction of the system carrier.
- the clamping force can then act, for example, in the insertion or wedge direction, so that the clamping force is applied transversely thereto through the wedge effect.
- the connection arrangement can preferably allow the clamping force to be applied gradually, for example by means of a screw connection, a screw preferably extending transversely to the system carrier, so that the clamping arrangement can preferably be tensioned by tightening the screw.
- the connecting arrangement can comprise one or more connecting elements on which the clamping rod can be acted upon in the direction of the system carrier. It preferably comprises at least a first connecting element and a second connecting element which are spaced apart from one another in the longitudinal direction of the system carrier. Viewed in the longitudinal direction of the system carrier, at least some, preferably all of the stripper modules are arranged between the first and second connecting element, particularly preferably the connecting elements are each arranged in the end area of the clamping rod and / or system carrier, i.e. easily accessible from the side.
- the module carrier and / or the clamping rod are articulated to the system carrier at at least one point, that is, in such a way that at least during one step of the assembly or Disassembly of the module carrier and / or the clamping rod can be swiveled away from the system carrier.
- a joint can preferably be provided in an end area of the system carrier, clamping rod and / or module carrier.
- the module carrier can be designed in one piece and, for example, extend over the entire width of the conveyor belt.
- the module carrier preferably has a plurality of module carrier segments which are arranged in alignment with one another and can be separated from one another.
- Such a separation into module carrier segments is advantageous because the module carrier preferably extends over the entire width of the conveyor belt and can thus have a considerable length, which is detrimental to handling.
- the division into two module carrier segments can cut the length in half, so that handling is significantly easier.
- the module carrier can preferably be divisible into 3 or more module carrier segments. This is particularly important when working in confined spaces or on narrow catwalks if there is not enough space to pull out a module carrier to the side over its full length.
- the module carrier segments can be connected, for example, by the system carrier alone, i.e. the module carrier segments can be connected independently of one another and only through their respective attachment to the system carrier. However, the module carrier segments are preferably connected directly to form a module carrier, also independently of the system carrier.
- connection of the module carrier segments can be done in various ways, in particular also by screw connections, etc. Preference is given, as will be explained in more detail below, a connection that can be separated without tools, in particular a plug connection.
- This can in particular be formed in such a way that it can be produced and / or detached by moving the module carrier segments relative to one another in an insertion direction.
- a lock can be provided to secure the plug connection.
- this can have a locking element extending transversely, preferably at right angles to the insertion direction.
- the locking element can preferably be movable in its longitudinal direction in order to establish or cancel the locking.
- the plug-in direction of the connector is preferably transverse to the longitudinal direction of the system carrier, particularly preferably at a right angle, while the locking element preferably extends in the longitudinal direction of the system carrier and is also inserted in this direction.
- the locking element can preferably be a rod or a tube, for example with a round or rectangular cross-section.
- the locking element preferably forms a form fit with the module carrier segments, for example it can encompass or cover them.
- the form-fitting coupling preferably provides that the module carrier segments partially or preferably completely encompass the locking element.
- the module carrier segments particularly preferably have a longitudinal bore through which the locking element engages. In particular, several module carrier segments can be pushed onto the locking element one behind the other. The combination of the aforementioned plug connection with such a locking element is particularly preferred.
- a module carrier segment represents a separate aspect of the invention, which can preferably be used for the above-described embodiments of wiper systems.
- This carries one or more wiper modules, which are preferably firmly attached to it and can be designed differently depending on the intended use.
- the module carrier The gersegment is designed to form a plug connection with a further and preferably identically designed module carrier segment arranged in front of and behind it (in the longitudinal direction of a system carrier). It comprises a longitudinal bore for receiving a locking element.
- the module carrier segment has a plug element at a first end which extends in a direction transverse to the longitudinal direction. At a second, opposite end, it has a receiving opening for a plug element, which is arranged in a direction transverse to the longitudinal direction, that is, enables a plug element to be inserted in this transverse direction and the formation of a form-fitting connection as a result.
- module carrier segments can thus be arranged one behind the other, coupled by means of the respective plug connections and finally locked by inserting the locking element into the preferably aligned longitudinal bores.
