Definitions

  • the invention relates to a device for monitoring a conveyor system, comprising:
  • At least one detectable segment which is embedded near the surface in the support side and / or running side;
  • a detection system in particular in the form of an optoelectronic system, which records and evaluates the detectable segment without contact, in particular in conjunction with a process computer;
  • the detection system used was in particular the use of optoelectronic systems, in particular in the form of electronic systems Camera systems (line camera or area camera), proposed, reference being made to the following prior art:
  • the detectable segment is, for example, a transponder in conjunction with an antenna (WO 2005/02388 A1, Fig. 1).
  • Conveyor belts with fabric or steel cable carrier possibly supplemented by heat-resistant inserts made of metal or plastic as protection against the burning of embers, and on both sides with elastomeric cover plates (support side, running side) are often used for the promotion of particularly warm material.
  • heat-resistant conveyor belts are mainly used in steel mills, foundries, cement works, coking plants and in the chemical industry. These are usually short plants of less than 200 m.
  • Conveyor belts for normal use for example, in the extraction of raw materials such as coal, salt, gravel, etc., are generally based on the materials natural rubber (NR) or styrene butadiene (SBR).
  • NR natural rubber
  • SBR styrene butadiene
  • the heat resistance of such rubber compounds is up to 80 0 C. With prolonged temperature excessive stress it comes to hardening of the rubber up to the breaking up and flaking of the cover plates. The conveyor belt is thus unusable.
  • EPDM ethylene-propylene-diene copolymer
  • HR butyl rubber
  • CR chloroprene
  • the object of the invention is therefore to provide a generic device in which the temperature development of a conveyor belt with respect to an undesirable temperature profile is observable.
  • the detectable segment is based on a thermochromic substance, which causes a change in color within temperature within the critical temperature range of a conveyor belt, wherein the detection system detects and evaluates the color change.
  • Thermochromism occurs when temperature changes in a substance cause a color change. Examples: The red ruby turns green when heated, and red when cooled. The white mercury I chloride turns yellowish upon gentle warming. Pure zinc oxide is colorless at ordinary temperature, yellow in heat. Mennige turns dark when heated, red when cooling.
  • thermochromic substance for the conveyor belt should be up to 300 0 C resistant, this limit temperature is well above the resistance of elastomers, the resistance - as stated above - depends on the elastomer type.
  • thermochromic substance within the critical temperature range (8O 0 C to 15O 0 C) of conveyor belts occur. It is particularly useful when at 80 ° C (first critical point) a first color change and at 15O 0 C (second critical point), a significant second color change occurs, so that no later than measures (alarm signal and / or automatic stoppage of the conveyor) to meet are.
  • thermochromic substance causes reversible color changes with regard to temperature changes, in that the original color state occurs during the cooling process.
  • example 1 blue ⁇ H> red
  • example 2 blue ⁇ -> transitional color ⁇ -> red
  • thermochromic substance based on a polymeric compound having a color change characteristic associated with a change in the polymeric molecular structure causing the color change.
  • the polymeric compound is preferably a polyacetylene (polyyne) which has reactive triple bonds.
  • Polyacetylenes are readily polymerizing organic compounds that are quite insensitive to oxygen. In contrast, hydrogen is easily attached.
  • the polymers are brown to red in the case of the diacetylene compounds, and dark blue in the tetraacetylenes.
  • These polymeric compounds are also characterized by a temperature-dependent color change characteristic. They are therefore particularly well suited for the application of conveyor belts.
  • the detectable segment comprises in particular a matrix in which the thermochromic substance is embedded uniformly distributed.
  • the proportion of the thermochromic substance within the matrix is 0.5 to 5 wt .-%, in particular 1 to 3 wt .-%.
  • the matrix itself consists of an elastomeric material, a thermoplastic elastomer (TPE) or a thermoplastic.
  • TPE thermoplastic elastomer
  • the matrix preferably consists of an elastomer mixture based on polybutadiene.
  • FIG. 1 shows a conveyor system with an opto-electronic system
  • Fig. 2 shows a conveyor belt with a thermochromic segment within the support side.
  • Fig. 1 shows a conveyor system 1, comprising a conveyor belt 2 made of elastomeric material having a support side 3 for the conveying material and a running side 4. The conveying material with the transport direction in the arrow direction is dropped at the reversing drum 5.
  • a detection system 6 in the form of an opto-electronic system detects the support side 3 of the conveyor belt 2 within its material-free area, in particular immediately after the discharge of the conveying material to the reversing drum 5.
  • the visual query of the color by means of the detection system in Connection to a process computer.
  • the process computer is in an optimal way with the drive control of the conveyor system in connection, so that when a critical condition, the system is automatically shut down.
  • Fig. 2 shows details of the conveyor belt 2 with the support side 3 and the running side 4 and an embedded strength member 7 in the form of a Gewebzugambas.
  • the conveyor belt may also have an embedded transverse reinforcement (e.g., steel transverse reinforcement).
  • At least one detectable segment 8 is embedded near the surface.
  • the segment is arranged here within the conveyor belt center. Also, the arrangement principle of two or more segments next to each other, under detection of the two edge regions of the conveyor belt are possible.
  • the area dimension of a generally rectangular segment is about 100 x 100 mm, so that this may also be detectable with the eye of the inspection personnel as a human detection system.
  • the detectable segment 8 comprises a matrix in which the thermochromic substance is incorporated uniformly distributed. In this way, the segment is easy to install in the conveyor belt cover plate. Also, such a segment may be implemented by vulcanization in the endless loop of the conveyor belt. A retrofit on site is possible.
  • the thermochromic substance now changes color depending on the temperature. This may appear (to 8O 0 C) blue in the non-critical area, while in the critical range (80 ° to 15O 0 C) enters a color change, in particular in the form of red. Even color shades (intermediate colors of blue / red) within the critical range are possible.
  • the detection system 6 may be equipped so that at determined temperature (eg 12O 0 C) the appropriate measures (alarm signal and / or automatic standstill of the conveyor system) are triggered.
  • This detection measure can also ensure that either conveyor temperature is lowered or a conveyor belt with higher temperature resistance is used.
  • Conveying system Conveyor belt Support side Operating side Reverse drum Detection system (optoelectronic system) Reinforcement member Detectable segment (thermochromic segment)
