- Belt alignment issues can affect material conveying operations. For example, if a conveyor belt becomes misaligned, material may be lost as it is conveyed via the belt. In some circumstances, such belt alignment issues can be difficult to address. Often, the conveyor has to be shut down so that the belt can be properly aligned. This can incur a substantial cost in terms of lost operational time in addition to the time and costs associated with realigning the belt.

In some embodiments, at least two sensors (31) can be utilized to detect an operational condition of the belt (7) indicating an undesirable alignment of the belt as the belt moves to convey material.

Description
- The present innovation relates to material conveying apparatuses. For example, the present innovation relates to the conveying of material (e.g. ore, rock, minerals, comminuted material, etc.), conveying devices such as, for example, pipe conveyors, mechanisms for controlling and/or adjusting operation of conveyor devices, kits for upgrading conveyor apparatuses, and methods of making and using the same.
- Conveyor devices can include devices that utilize a continuous belt to convey material between different locations. Examples of conveyor devices can be appreciated from U.S. Pat. Nos. 8,610,008, 8,177,055, 8,177,054, 8,033,385, 6,155,400, 6,079,551, 5,222,594, 5,163,663, and 5,090,549, U.S. Pat. App. Pub. Nos. 2012/0251246 and 2012/0247915, and Chinese Utility Model Patents CN 204223727 U and CN 205471349 U. Belt alignment issues can affect material conveying operations. For example, if a conveyor belt becomes misaligned, material may be lost as it is conveyed via the belt. In some circumstances, such belt alignment issues can be difficult to address. Often, the conveyor has to be shut down so that the belt can be properly aligned. This can incur a substantial cost in terms of lost operational time in addition to the time and costs associated with realigning the belt.
- We have determined that a new conveyor belt apparatus and a new control mechanism for conveyor belt apparatuses can be utilized to improve conveyor apparatus operations to reduce operational down times relating to belt alignment issues. We have also developed a new methodology that can be employed for monitoring operation of a conveyor apparatus and adjusting operations of the conveyor device to improve conveyor apparatus performance and reduce operational down times relating to belt alignment issues.

In this regard, at least one upper frame segment moves relative to the lower frame segment to which the upper frame segment is connected via slideable connection mechanisms (17) and the pivotal connection mechanism (19) to induce the overlap portion to rotate back toward the top central position as the belt moves to convey material, without limitation.
- The conveyor apparatus may comprise a controller (11) having non-transitory memory (11 b) communicatively connected to a processor (11 a), the controller (11) communicatively connected to the sensors (31) to receive sensor data from the sensors (31), the controller configured to determine, from the sensor data, that the overlap portion (7 e) of a middle segment (7 d) of the upper run (7 a) of the belt (7) has rotated away from the top central position such that rotation of the overlap portion (7 e) meets a first pre-selected rotational threshold, without limitation.
- The controller (11) of the conveyor apparatus may be configured to initiate actuation of at least one actuator (17 a) in response to determining that the overlap portion (7 e) has rotated such that the first pre-selected rotational threshold is met or exceeded so that at least one upper frame segment moves relative to the lower frame segment to which the upper frame segment is connected via slideable connection mechanisms (17) and the pivotal connection mechanism (19) to induce the overlap portion to rotate back toward the top central position as the belt moves to convey material, without limitation.
- Actuators may be provided to the conveyor apparatus to actuate motion of the upper frame segments relative to the lower frame segments via at least one of the slideable connection mechanisms (17) and the pivotal connection mechanisms (19), without limitation. Each of the upper frame segments may have a plurality of idlers positioned to define an aperture through which the
belt 7 is passable when the belt is in the pipe configuration such that an external side (7 g) of the belt (7) is contacted by the idlers as the belt passes through the aperture, without limitation. - A method of operating a conveyor apparatus (1) is further disclosed. The method may include the use of a conveyor apparatus (1) as hereforeto described; for example, a conveyor apparatus (1) comprising: a moveable belt (7) supported by a frame (9), the moveable belt (7) moveable between a material loading end and material discharge end, the moveable belt having an upper run (7 a) and a lower run (7 b); and the frame (9) comprising upper frame segments (9 e) connected to lower frame segments (9 f), without limitation. The method may involve the step of a plurality of sensors (31) monitoring an overlap portion (7 e) of a middle segment (7 d) of an upper run (7 a) of a belt (7) as the belt (7) moves in a pipe configuration to convey material. The method may also involve the step of detecting the overlap portion (7 e) rotating during motion of the belt to convey material such that a first pre-selected rotational threshold is met that indicates the overlap portion has rotated too far away from a top central position via sensor data received from the sensors (31). In response to detecting the first pre-selected rotational threshold is met, at least one of the following steps may be performed: (i) communicating at least one warning; and (ii) initiating motion of upper frame segments (9 e) of the frame (9) relative to lower frame segments (9 f) of the frame (9) to induce rotation of the overlap portion (7 e) toward the top central position as the belt (7) is moved to convey material, without limitation. In some embodiments, both of the aforementioned steps of (i) communicating the at least one warning; and (ii) initiating motion of the upper frame segments (9 e) of the frame (9) relative to lower frame segments (9 f) of the frame (9) may be performed, without limitation. In some embodiments, the step of initiating of motion of the upper frame segments (9 e) of the frame (9) relative to the lower frame segments (9 f) of the frame (9) to induce rotation of the overlap portion (7 e) toward the top central position as the belt (7) is moved to convey material may be performed in response to detecting the first pre-selection rotational threshold is met or exceeded.
- In some embodiments, the motion of the upper frame segments (9 e) of the frame (9) relative to the lower frame segments (9 f) of the frame (9) to induce rotation of the overlap portion (7 e) toward the top central position as the belt (7) is moved to convey material may comprise upper frame segments moving relative to lower frame segments via slideable connection mechanisms moveably connecting the upper frame segments to the lower frame segments, without limitation. The motion of the upper frame segments (9 e) of the frame (9) relative to the lower frame segments (9 f) of the frame (9) to induce rotation of the overlap portion (7 e) toward the top central position as the belt (7) is moved to convey material may comprise upper frame segments rotating via pivotal connection mechanisms (19) rotatably connecting the upper frame segments to the a peripheral upper portion of the frame (9), without limitation.

FIGS. 1-8 , a conveyor apparatus 1 can includes abelt 7 that extends between material loading device 3 to amaterial discharge device 5. The belt can be configured as a continuous belt and include an uppermaterial transport run 7 a that extends between the material loading device 3 and thematerial discharge device 5 and a lowerreturn belt run 7 b that extends between the material loading device 3 and thematerial discharge device 5. The material loading device 3 can be configured as (and/or include) a hopper, guide, or other feed element or feed conduit that can deliver material to be conveyed to thebelt 7. The material can be received from a comminution device or from a truck or other vehicle that may deliver the material to the material loading device 3 or a conduit connected to the material loading device 3. - The
material discharge device 5 can include a hopper that receives material from a discharge end of the conveyor belt'supper run 7 a. The material may be conveyed off thebelt 7 and into the material discharge device as thebelt 7 moves around a fixed pulley defining the discharge end of thebelt 7 to reverse directions from moving in a first direction 12 (e.g. a forward direction or rearward direction) in which theupper run 7 a of the belt moves from the material loading device 3 to thematerial discharge device 5 to a second direction 14 (e.g. a forward direction or rearward direction that is opposite the first direction 12) in which thelower run 7 b of thebelt 7 moves from thematerial discharge device 5 to the material loading device 3. - The
belt 7 can be supported by aframe 9. The frame can be structured to extend from the ground or a support structure installed on the ground or supported on the ground to support thebelt 7 in an elevated position that is above the ground. Theframe 9 can be configured to support the belt so that the upper andlower runs end sections 7 c in which the belt is flat and extends horizontally from afirst side 4 to asecond side 6. The first andsecond sides belt 7 and the material discharge end of the belt. The material receiving end of thebelt 7 can include a portion of the belt that extends from thelower run 7 b to theupper run 7 a by curving, or bending, around afirst pulley 8 positioned to define the material receiving end of thebelt 7. The material discharge end of the belt can include a portion of the belt that extends from theupper run 7 a to thelower run 7 b by curving, or bending, around asecond pulley 10 positioned to define the material discharge end of thebelt 7. The material discharge end of the belt moves about its discharge end so that it changes directions as it moves along thesecond pulley 10 from moving in the first direction 12 (toward the material discharge device 5) to moving in the second direction 14 (toward the material loading device 3). The material loading end of the belt also changes directions as it moves along thefirst pulley 8 from moving in thesecond direction 14 to moving in thefirst direction 12. During the reversal of directions that occurs at the material loading end of the belt as thebelt 7 curves or bends around thefirst pulley 8, thebelt 7 can move vertically upwardly from thelower run 7 b to theupper run 7 a. During the reversal of directions that occurs at the material discharge end of the belt, the belt can move vertically downwardly during its motion around thesecond pulley 10 as thebelt 7 passes from theupper run 7 a to thelower run 7 b. A motor M (as indicated in broken line inFIG. 1 ) can be connected to thefirst pulley 8 or to thesecond pulley 10 to drive rotation of the pulley to which the motor M is coupled for driving motion of thebelt 7. - The
frame 9 can also support the belt so that themiddle segment 7 d of theupper run 7 a that is between theend sections 7 c of theupper run 7 a of thebelt 7 defines a closed pipe (e.g. is curved into an annular-type shape to form a pipe-like structure or tubular structure between theend sections 7 c) for conveying material within achannel 7 h defined inside thebelt 7. Thechannel 7 h can have a diameter that defines its width.Material 21 can be conveyed within the channel when the belt is moved into its closed pipe shape. The pipe shape of the belt can be formed by opposite side edges of the belt (e.g. the edges of the first andsecond sides 4 and 6) overlapping each other at anoverlap portion 7 e to define theannular structure 7 f of the belt of themiddle segment 7 d of theupper run 7 a so thatmaterial 21 to be conveyed via the belt is enclosed within aninner channel 7 h defined by the tubular shapedmiddle segment 7 d. Theframe 9 can also support the belt so that themiddle segment 7 d of thelower run 7 b that is between theend sections 7 c of thelower run 7 b a is curved into a circular-type shape to form a pipe or tubular structure between theend sections 7 c that define aninner channel 7 h. Opposite side edges of thebelt 7 may overlap at theoverlap portion 7 e to define the pipe structure of themiddle segment 7 d of theupper run 7 a of the belt (e.g. the annular or tubularstructure defining channel 7 h). - A
controller 11 can be connected to a motor M and other elements of the conveyor apparatus 1 to monitor and/or control operations of the conveyor apparatus. Thecontroller 11 can be configured as a computer device that includes aprocessor 11 b that is communicatively connected tonon-transitory memory 11 a and at least onetransceiver 11 c. Thecontroller 11 can be configured to run one or more programs stored in thememory 11 a (e.g. flash memory, a hard drive, etc.). The controller can be communicatively connected to a motor M that is connected to at least one of thefirst pulley 8 and thesecond pulley 10 that drives rotation of at least one of thefirst pulley 8 andsecond pulley 10 for motion of thebelt 7. Thecontroller 11 can also be communicatively connected to detector mechanism that are positioned to monitor operational conditions of thebelt 7. The monitored conditions that can be monitored or detected during operations can include the speed at which thebelt 7 moves, the location of the anoverlap portion 7 e of thebelt 7 that forms the pipe or tubular structure of themiddle segments 7 d of thebelt 7, and/or the rate at which material is being transported from the material loading end of the belt to the material discharge end of the belt. Thecontroller 11 can be communicatively connected to multiple spaced apartsensors 31 for performing this monitoring. At least some of thesesensors 31 may be connected to theframe 9 for positioning the sensors to detect conditions relating to the operation and/or motion of thebelt 7. The communicative connection can be provided by a communication link that extends along a wired communication path, a wireless communication path, utilizes one or more intermediate nodes (e.g. a network access point or other type of node) or other type of communication path (e.g. a network communication link, a direct wired link, a direct wireless communication link, a communication connection that includes combination of such links, etc.). - The
frame 9 that supports thebelt 7 of the conveyor apparatus can include an upperbelt supporting portion 9 a and a lowerbelt supporting portion 9 b. The upperbelt supporting portion 9 a can be connected to the lowerbelt supporting portion 9 b so that the upperbelt supporting portion 9 a is positioned above the lowerbelt supporting portion 9 b and is moveable (e.g. rotatable, slideable, and/or pivotable, etc.) relative to the lowerbelt supporting portion 9 b. The upperbelt supporting portion 9 a and the lowerbelt supporting portion 9 b can each define acentral aperture 9 h through which thebelt 7 is movable when it is in its annular structure and is moving along itsmiddle segments 7 d. The upperbelt supporting portion 9 a can include a number of aligned, spaced apartupper frame segments 9 e that are each attached to a plurality ofidlers 13 to position thoseidlers 13 to define first uppercentral apertures 9 c through which the closed, tubularmiddle segment 7 d of theupper run 7 a of the belt can pass through such that theidlers 13 can contact the outer,exterior side 7 g of the pipe shapedbelt 7 as thebelt 7 is passed through the first uppercentral apertures 9 c. In some embodiments, eachupper frame segment 9 e can be configured as an idler panel of theframe 9, for example. The lowerbelt supporting portion 9 b can include a number of aligned, spaced apartlower frame segments 9 f that are each attached to a plurality ofidlers 13 to position thoseidlers 13 to define aligned second lowercentral apertures 9 d through which the closed, tubularmiddle segment 7 d of thelower run 7 b of the belt can pass through such that theidlers 13 can contact the outer,exterior side 7 g of the pipe shapedbelt 7 as the belt is passed through the second lowercentral apertures 9 d. In some embodiments, eachlower frame segment 9 f can be configured as an idler panel of theframe 9, for example. - The
frame 9 can also include other structure connected to the upper belt supportingframe portion 9 a and/or lower belt supportingframe portion 9 b to position the frame within a building or plant and/or position the upper belt supportingframe portion 9 a and/or lower belt supportingframe portion 9 b above the ground to support thebelt 7 above the ground. Posts, cross-beams, concrete slabs, and other structures may be included in theframe 9 or attached to theframe 9 to facilitate such positioning of the upper belt supportingframe portion 9 a and/or lower belt supportingframe portion 9 b. Such structure can include cross braces that may extend between spaced apartlower frame segments 9 f, cross braces that extend around a peripheral frame structure between spaced apartlower frame segments 9 f, spaced apartupper frame segments 9 e, at least oneupper support beam 9 m of a peripheral frame structure of theframe 9 that is attached to the spaced apart, innerupper frame segments 9 e,lower support beams 9 n of an outer peripheral frame structure of theframe 9 attached to the spaced apart, innerlower frame segments 9 f, and crossbeams 90 that extend betweenlower support beams 9 n. - In some embodiments, the relative motion of the upper belt supporting
frame portion 9 a relative to the lower belt supportingframe portion 9 b can be provided be at least one of: (i) use ofslideable connection mechanisms 17 that connectupper frame segments 9 e tolower frame segments 9 f so that eachupper frame segment 9 e is moveably attached to a respectivelower frame segment 9 f viaslideable connection mechanisms 17, (ii) upperpivotal connection mechanisms 19 that are each attached to a respectiveupper frame segment 9 e so that theupper frame segment 9 e is pivotally connected to a peripheral frame structure (e.g.upper beam 9 m) of theframe 9, and (iii) the combination ofslideable connection mechanisms 17 andpivotal connection mechanisms 19. In some embodiments, there can be at least twoslidable connection mechanisms 17 that attach anupper frame segment 9 e to alower frame segment 9 f at opposite sides of the frame segments, as shown for example inFIGS. 2 and 3 . Theslidable connection mechanisms 17 can be positioned on each and every pair ofupper frame segments 9 e andlower frame segments 9 f or can only be utilized in some of these connected together segments. Thepivotal connection mechanisms 19 can be positioned on each and every one of theupper frame segments 9 e or can only be positioned on some of theupper frame segments 9 e at spaced apart locations located between the first andsecond pulleys - Each
slideable connection mechanism 17 can include an assembly that includes at least onepin 17 b (e.g. a bolt, a rod, a bar, a fastener, a member, a rigid element, etc.) that extends from thelower frame segment 9 f through aslot 17 c defined in a body attached to theupper frame segment 9 e. Thepin 17 b can extend from thelower frame segment 9 f through theslot 17 c. In other embodiments, thepin 17 b can extend from theupper frame segment 9 e to thelower frame segment 9 f and theslot 17 c can be defined in a body attached to thelower frame segment 9 f such that theupper frame segment 9 e is moveable relative to thelower frame segment 9 f. - One or more retainers (e.g. one or more nuts, a cap, etc.) can be attached to a distal end of the
pin 17 b (e.g. an upper end of a pin that extends from thelower frame segment 9 f or a lower end of the pin that extends from anupper frame segment 9 e) to keep the pin retained within theslot 17 c so that the body that defines theslot 17 c is slideable relative to thepin 17 b andlower frame segment 9 f from which the pin extends from the first end of the slot to the opposite second end of theslot 17 c such that the length L of theslot 17 c can define the path of motion. In other embodiments where the pin extends from theupper frame segments 9 e, the retainer can be connected to the distal end of the pin so that the pin is moveable within theslot 17 c relative to thelower frame segment 9 f and body defining theslot 17 c. - An actuator 17 a can be configured as a hydraulic cylinder or other type of actuator. The actuator 17 a can be configured to move the
upper frame segment 9 e so that the body that defines theslot 17 c to which the upper frame segment is attached or thepin 17 b to which the upper frame segment is attached moves to drive motion of theupper frame segment 9 e relative to thelower frame segment 9 f along a path of travel defined by the length L of theslots 17 c through which pins 17 b extend. In some embodiments, the actuator 17 a can be connected to theframe 9 so that an extendable arm of the actuator extends from an outer frame element to theupper frame segment 9 e to drive motion of the upper frame segment via thepins 17 b andslots 17 c of theslideable connection mechanisms 17 that moveably attach theupper frame segment 9 e to thelower frame segment 9 f. In some embodiments, there may be a single actuator that is attached to an upper frame segment for motion of theupper frame segment 9 e relative to thelower frame segment 9 f about two or moreslideable connection mechanisms 17. In other embodiments, there may be an actuator 17 a connected to a respectiveslideable connection mechanism 17 at each side of a moveable upper frame/lower frame segment connection that can be actuated to drive motion of theupper frame segment 9 e relative to thelower frame segment 9 f to which it is moveably attached viaslideable connection mechanisms 17. - The
upper frame segments 9 e can also be pivotally connected to a top element, or an upper external element of theframe 9 via apivotal connection mechanism 19. Eachupper frame segment 9 e can include such a connection or a plurality of spaced apart upper frame segments (but not allupper frame segments 9 e) can include such pivotal connections. In some embodiments, each pivotal connection can include apivotal connection mechanism 19 that connects a peripheral upper beam 19m of the frame (e.g. a top beam that is at a periphery of the frame or is at least more outwardly positioned than the innerupper frame segment 9 e) to theupper frame segments 9 e. Thepivotal connection mechanism 19 between the upper beam 19 m and theupper frame segment 9 e can be configured so that theupper frame segment 9 e is rotatable relative to thelower frame segment 9 e and relative to the top beam 19 m. In other embodiments, the pivotal connection of theupper frame segment 9 e can be to a different frame element that is positioned above the upper frame segment, but is not a top beam (e.g. an upper cross beam or an upper frame element that is positioned outside of theupper frame segment 9 e and above theupper frame segment 9 e, etc.). - Each
pivotal connection mechanism 19 can include anupper assembly 19 a that is attached to the top beam 19 m or otherupper frame segment 9 e of theframe 9. Anelongated member 19 b can extend along its height H from theupper assembly 19 a through a portion of theupper frame segment 9 e. For example, theupper frame segment 9 e can include an upper body that defines a hole through which theelongated member 19 b extends and is configured to facilitate rotation of theupper frame segment 9 e about the axle defined by theelongated member 19 b positioned in that hole. The height H of theelongated member 19 b can define avertical axis 19 c about which the upper frame segment 19 e is rotatable. Such rotation of the upper frame segment 19 e can permit horizontal rotational movement of the upper frame segment about thevertical axis 19 c relative to the upper beam to which it is attached and thelower frame segment 9 f to which it is attached. This rotational motion can occur when the arms of one ormore actuators 17 a are moved to slide theupper frame segment 9 e relative to thelower frame segment 9 f via theslideable connection mechanisms 17 connecting thelower frame segment 9 f to theupper frame segment 9 e. - The conveyor apparatus 1 can also include a plurality of spaced apart
sensors 31. Thesensors 31 can be configured as laser sensors that can be mounted on both sides of thebelt 7 nearupper frame segments 9 e that supportidlers 13 and/or thefirst pulley 8 andsecond pulley 10. The laser sensors can monitor rotation of theoverlap portion 7 e of themiddle segment 7 d of theupper run 7 a of thebelt 7 as the belt moves (e.g. can monitor conveyor pipe rotation for themiddle segment 7 d of theupper run 7 a). Thesensors 31 can also be positioned to monitor rotation of theoverlap portion 7 e of themiddle segment 7 d of thelower run 7 b of thebelt 7 as the belt moves (e.g. can monitor conveyor pipe rotation for themiddle segments 7 d of thelower run 7 b). Thesesensors 31 can be positioned so that they can monitor rotation of theoverlap portion 7 e of thebelt 7 in either direction (clockwise or counterclockwise) between a specified range (+/−30° to +/−100°, +/−30°, +/−45°, +/−60°, +/−90°, +/−95° etc.). Thesensors 31 can be configured to continuously monitor the belt as it is moving to convey material and, if there is pipe rotation, detect thebelt overlap portion 7 e when it comes within apre-selected safety 10 rotational range (e.g. a pre-selected rotational threshold being met). Upon such a detection, the sensors can communicate with thecontroller 11 or an output device to emit at least one warning. The warnings can include a first notification warning that provides an audible and/or a visual warning for a human operator to take notice of the detected condition defined by a first pre-selected rotational threshold (e.g. +/−15°, +/−30° , etc.), a subsequent second warning defined by a second pre-selected rotational threshold (e.g. +/−20°, +/−45°, etc.) for operation personnel to take corrective action when the second pre-selected rotational threshold is met, and finally a third warning defined by a third pre-selected rotational threshold (e.g. +/−30°, +/−60°, +/−90°, +/−100°, etc.) to trip automatic action to ensure operations personnel take corrective action in order to minimize damage so that a major break down of thebelt 7 or conveyor apparatus can be avoided upon the third pre-selected rotational threshold being met or exceeded. - The
sensors 31 can be configured as belt alignment detectors for a belt alignment detection mechanism that is communicatively connected to thecontroller 11. For example, a pair of spaced apartsensors 31 can be attached to theframe 9 adjacent to theupper frame segments 9 e, to theupper frame segments 9 e, or otherwise positioned near theupper frame segments 9 e so that each sensor of the pair of sensors is adjacent opposite sides of the frame segment to which the pair of sensors is attached and/or adjacent. Such pairs ofsensors 31 can also be positioned adjacent thelower frame segments 9 f or by thelower frame segments 9 f on opposite sides of the frame segments. There may be one or more pairs ofsensors 31 attached adjacent to eachupper frame segment 9 e and a pair of spaced apartsensors 31 attached to eachlower frame segment 9 f. In other embodiments, there may be pairs ofsensors 31 or more than twosensors 31 positioned adjacent to at least some of theupper frame segments 9 e for monitoring themiddle segment 7 d of theupper run 7 a of the belt. There may also be pairs of sensors (or more than two sensors 31) positioned adjacent to at least some of thelower frame segments 9 f for monitoring themiddle segment 7 d of thelower run 7 b of the belt. - The
overlap portion 7 e of thebelt 7 when the belt is in an annular structure configuration (e.g. a tubular or pipe configuration) is desired to be maintained at an upper middle location of the belt to avoidmaterial 21 falling out of thechannel 7 h defined via the annular structure of thebelt 7. The most preferred position for theoverlap portion 7 e is a top central position as shown, for example, inFIG. 6 . But, during operation, thebelt 7 can rotate so that theoverlap portion 7 e is rotated from this central top position in a clockwise direction an can also rotate in a counterclockwise direction. - The
sensors 31 can be configured to monitor a position of theoverlap portion 7 e of thebelt 7 when the belt defines an annular structure having thechannel 7 h in whichmaterial 21 is transportable. The spaced apartsensors 31 can be positioned so that, for each frame segment to which the sensors are adjacent, there is afirst sensor 31 adjacent a first side of the frame segment and a second sensor adjacent a second side of the frame segment that is opposite the first side (e.g. there is at least onesensor 31 on a right side of thebelt 7 and a right side of the frame segment and asecond sensor 31 on a left side of thebelt 7 and a left side of the frame segment, etc.). Eachsensor 31 can be configured to emit a detection signal 33 (e.g. a laser beam, beam of visible light, beam of infrared light, etc., a radio signal, or emit other media) to sense a position of theoverlap portion 7 e of the belt). In some embodiments, a pair of spaced apartsensors 31 can be mounted to theframe 9 or otherwise positioned adjacent anupper frame segment 9 e so that the sensors are above the top of theoverlap portion 7 e of themiddle segment 7 d of theupper run 7 a of thebelt 7 and emit adetection signal 33 at the belt at an angle. Eachsensor 31 can provide a detection of up to 100° of rotation of theoverlap portion 7 e from its top central position so that the spaced apartsensors 31 can detect a rotation of theoverlap portion 7 e from a central top position to a position that is rotated between a range of +/−100° relative to this central top position of theoverlap portion 7 e (e.g. a range of up to 100° rotation that is counterclockwise from the central top position to a rotation of up to 100° rotation that is in a clockwise direction from the central top position). Upon a detection by one of thesensors 31 or both of thesensors 31 that the overlap portion has rotated away from the top central position to a position that exceeds a pre-selected rotational threshold that defines a motion of theoverlap portion 7 e that is too far away from the desired top central position (e.g. a rotation of 100°, 60°, 45°, 30°, or 20°, etc. away from the top central position), the data of the sensors can be used by thecontroller 11 to detect this condition and emit a warning or alarm for actuation of a change in operations to move the overlap portion toward its top central position and/or automatically communicate withactuators 17 a and/or motor M to adjust operation of the conveyor apparatus 1 to effect a change in the belt motion to move theoverlap portion 7 e back toward the top central position or take other corrective action that may be needed due to the detected position of theoverlap portion 7 e. - Of course, instead of a pair of sensors, three or more sensors could be used or just one
sensor 31 could be used adjacent different frame segments to provide a different range of detection for theoverlap portion 7 e of thebelt 7 when the belt is in its annular configuration (e.g. pipe or tubular configuration) that defineschannel 7 h. But, for many applications, a range of +/−100° rotation will be sufficient for detection purposes. In some embodiments, a smaller range (e.g. +/−30° or +/−45° or +/−60°) may be desired to emit a warning or alarm for actuation of a change in operations to move the overlap portion toward its top central position. - One consideration that can be made in selecting the one or more pre-selected rotational thresholds that can define a motion of the
overlap portion 7 e that is considered to be too far away from the desired top central position is false alarms in which the rotational tolerance for theoverlap portion 7 e is so narrow that the belt operation is almost always being adjusted. Such a tight tolerance is undesirable as it can require changes to conveyor apparatus operations too often, which can detrimentally affect the efficient operation of thebelt 7. A pre-selected rotational threshold is therefore most preferably selected to be a 30°, 45°, 60°, 75°, or 90° threshold (e.g. not less than 30° and not more than 100°) so that any clockwise or counterclockwise rotation from the top central position that is at or beyond this threshold value triggers an alarm and/or an automatic adjustment of conveyor apparatus 1 to adjust the operation of thebelt 7 to move theoverlap portion 7 e back to the top central position or toward a position within the pre-selected rotational threshold of that top central position. - The
controller 11 can be configured to communicate with thesensors 31 to receive measurement data from the sensors or detection data from the sensors that relate to the location of theoverlap portion 7 e of themiddle segments 7 d of thebelt 7 as thebelt 7 is moved for conveyingmaterial 21. Thecontroller 11 can be configured to use this received sensor data from thesensors 31 to determine when the overlap portion has rotated too far away from the top central location. The controller can also be configured (or alternatively be configured) to receive sensor data from one or more of thesensors 31 indicating that theoverlap portion 7 e has rotated too far away from the top central location. Upon thecontroller 11 determining from the sensor data received from thesensors 31 that theoverlap portion 7 e of thebelt 7 is rotated too far away from the desired top central position (e.g. being at or exceeding the pre-selected rotational threshold via clockwise rotation or via counterclockwise rotation), the controller can communicate a signal or other data for emitting a warning (e.g. a visible warning that may be displayed on a display device communicatively connected to thecontroller 11 for display to a user or operator, an emission of an audible warning via a speaker communicatively connected to the controller, an emission of a flashing light via a light that is connected to the controller, combinations thereof, etc.). In addition, or as an alternative, thecontroller 11 can be configured to communicate with at least oneactuator 17 a, the motor M, and other belt motion movement mechanism (e.g. a first pulley adjustment device configured to adjust a position or motion of thefirst pulley 8, a second pulley adjustment device configured to adjust a position or motion of the second pulley 10) for adjusting operation of the conveyor belt. - For example, upon a detection of the
overlap potion 7 e being at an undesired location via the received sensor data, thecontroller 11 can communicate withmultiple actuators 17 a to move differentupper frame segments 9 e relative to lowerframe segments 9 f to which thoseupper frame segments 9 e are attached via theslideable connection mechanisms 17 andpivotal connection mechanisms 19 for rotating the positions of the first andsecond pulleys actuators 17 a, theupper frame segments 9 e may be slid linearly relative to thelower frame segments 9 f via the slideable connection mechanisms 17 (e.g. slid left to right or right to left, or front to back, or back to front, etc.). Thepivotal connection mechanisms 19 can rotate during such linear motion of driven via the actuator(s) 17 a so that theupper frame segments 9 e rotate about vertical axes as they are slid linearly and/or horizontally (e.g. rotate counterclockwise or clockwise as they are moved linearly or horizontally left to right or right to left, or front to back or back to front, etc.). For example, upon detection that theoverlap portion 7 e has rotated too far in a counterclockwise direction, thecontroller 11 can communicate withactuators 17 a to move a firstupper frame segment 9 e that supports thefirst pulley 8 so that the upper frame segment rotates viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in a first rotational direction and so that a secondupper frame segment 9 e that supports thesecond pulley 10 rotates in a second rotational direction that is opposite this first rotation direction to induce a rotation of theoverlap portion 7 e in a clockwise direction toward its top central position as the belt continues to move to conveymaterial 21. Depending on the direction at which theupper run 7 a of belt is moving to convey material 21 (e.g. forwardly or rearwardly, etc.), the actuated rotation of the first and second upper frame segments can be different such that a first actuator is actuated via thecontroller 11 to move the firstupper frame segment 9 e that supports thefirst pulley 8 so that the upper frame segment rotates viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in the second rotational direction and so that the secondupper frame segment 9 e that supports thesecond pulley 10 rotates in the first rotation direction to induce a clockwise rotation of theoverlap portion 7 e toward its top central position as thebelt 7 continues to move. - The
controller 11 can also be configured to actuate actuators in a similar fashion upon detection that theoverlap portion 7 e of themiddle segment 7 d of a run of the belt has rotated too far in a clockwise direction. Depending on the direction at which the belt is moved to conveymaterial 21, such actuation of motion can include either: (i) actuators 17 a moving the firstupper frame segment 9 e that supports thefirst pulley 8 so that the upper frame segment rotates viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in the first rotational direction and so that the secondupper frame segment 9 e that supports thesecond pulley 10 rotates in the second rotational direction that is opposite this first rotation direction to induce a counterclockwise rotation of theoverlap portion 7 e toward its top central position as thebelt 7 is moved to convey material or (ii) actuators 17 a moving the firstupper frame segment 9 e that supports thefirst pulley 8 so that the upper frame segment rotates viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in the second rotational direction and so that the secondupper frame segment 9 e that supports thesecond pulley 10 rotates in the first rotational direction to induce a counterclockwise rotation of theoverlap portion 7 e toward its top central position as thebelt 7 is moved to convey material. - The
controller 11 can also be configured to move otherupper frame segments 9 e instead of upper frame segments that support the first andsecond pulleys second pulleys controller 11 can determined that theoverlap portion 7 e of theupper run 7 a of the belt in themiddle segment 7 d has rotated too far in a clockwise direction. Depending on the direction at which theupper run 7 a of thebelt 7 is moved to conveymaterial 21, such actuation of motion can include either: (i) actuators 17 a moving the first upstreamupper frame segment 9 e that supports a first set ofupstream idlers 13 so that the upstream upper frame segments rotate viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in the first rotational direction and so that a set of second downstreamupper frame segment 9 e that are downstream of the first set of upstreamupper frame segments 9 e and supportsdownstream idlers 13 rotate in the second rotational direction that is opposite this first rotation direction to induce a counterclockwise rotation of theoverlap portion 7 e toward its top central position as thebelt 7 is moved to convey material or (ii) actuators 17 a moving the first set of upstreamupper frame segments 9 e that support upstream idlers so that the first set of upstream upper frame segments rotate viaslidable connection mechanisms 17 andpivotal connection mechanism 19 in the second rotational direction and so that the second downstreamupper frame segments 9 e that support thedownstream idlers 13 rotate in the first rotational direction to induce a counterclockwise rotation of theoverlap portion 7 e toward its top central position as thebelt 7 is moved to convey material. Depending on the direction at which the upper run 7 a of the belt 7 is moved to convey material 21, the controller 11 can be configured to also actuate motion of upper frame segments in response to a determination that the overlap portion 7 e is rotated too far in a counterclockwise direction such actuation of motion can also include either: (i) actuators 17 a moving the first upstream upper frame segments 9 e that support a first set of upstream idlers 13 so that the upper frame segments rotate via slidable connection mechanisms 17 and pivotal connection mechanisms 19 in the first rotational direction and so that a set of second downstream upper frame segment 9 e that are downstream of the first set of upstream upper frame segments 9 e and support downstream idlers 13 rotate in the second rotational direction that is opposite this first rotation direction to induce a clockwise rotation of the overlap portion 7 e toward its top central position as the belt 7 is moved to convey material or (ii) actuators 17 a moving the first set of upstream upper frame segment 9 e that support upstream idlers 13 so that the first set of upstream upper frame segments rotate via slidable connection mechanisms 17 and pivotal connection mechanisms 19 in the second rotational direction and so that the second downstream upper frame segment 9 e that supports the downstream idlers 13 rotate in the first rotational direction to induce a clockwise rotation of the overlap portion 7 e toward its top central position as the belt 7 is moved to convey material. - The adjustments that can be made via the
controller 11 can occur automatically upon a detection of theoverlap portion 7 e rotating beyond a pre-selected rotational threshold as discussed herein. Examples of the adjustable actuation that can be provided in response to the sensor data received via thesensors 31 may best be appreciated fromFIGS. 7 and 8 in which thesecond pulley 10 can be considered a take-up pulley. As thebelt 7 is moving under load to conveymaterial 21, the belt7 can be monitored viasensors 31. Over time, during operation of the belt for conveying material, theoverlap portion 7 e of themiddle segment 7 d of theupper run 7 a of the belt may rotate away from its top central position. As such rotation of theoverlap portion 7 e occurs, thebelt 7 may no longer travel centrally when moving toward thesecond pulley 10 to convey material to the discharge end of the belt. As a result of this motion, the sensors may detect that the position of thesecond pulley 10 relative to the center of thebelt 7 exceeds or is below a pre-selected threshold value, such as, for example, 90°. Such a detection can occur by detecting theoverlap portion 7 e being rotated too far away from its top central position. In response to such a determination, thecontroller 11 can communicate with theactuators 17 to drive motion of theupper frame segments 9 e relative to thelower frame segments 9 f to adjust thebelt 7 as it is moved to induce rotation of the belt for better aligning the overlap portion toward its desired top central location in the middle segment of theupper run 7 a of thebelt 7 as the belt is moved. - The corrective action effected via the
controller 11 can be configured to occur in discrete steps or at the same time. In some embodiments, the controller can communicate withdifferent actuators 17 a so that allupper frame segments 9 e to be moved are moved at the same time (e.g. simultaneously). In other embodiments, the controller can communicate with the actuators so that different upper frame segments are moved at different times. For example, thecontroller 11 can first actuate motion ofupper frame segments 9 e that support the first andsecond pulleys belt 7 with the center of these pulleys. After the adjustment of those frame segments occur, thecontroller 11 can communicate with other actuators to actuate motion ofupper frame segments 9 e that supportidlers 13 to further induce alignment of the belt centrally. Adjustment of the upper frame segments that supportidlers 13 can adjust the positions of the idlers to provide an aligning impact on the belt to rotate theoverlap potion 7 e toward its top central location by causing a transverse shifting of thebelt 7 as it moves to rotate the belt so that theoverlap portion 7 e is moved back toward the top central location. - The adjustment of the
conveyor belt 7 can be actuated herein via input provided by a user in response to a warning communicated via thesensors 31 and/orcontroller 11. For example, the warnings can include a first notification warning that provides an audible and/or a visual warning for a human operator to take notice of the detected condition. The human operator may respond to such a first warning by paying more attention to a detected condition or by actuating one or more actuators to address the identified issue. A subsequent second warning can also be communicated via thesensors 31 and/orcontroller 11 for operation personnel to indicate to a human operator that input data should be provided to thecontroller 11 to initiate actuation ofactuators 17 a so that corrective action is taken for moving theupper frame segments 9 e. A third warning can subsequently be issued to trip automatic action via thecontroller 11 to ensure corrective action is taken (via adjustment of upper frame segments or belt motion shutdown) in order to minimize damage so that a major break down of thebelt 7 or conveyor apparatus can be avoided. The different warnings can each correspond to a different pre-selected threshold being met. Thus, the controller can utilize more than one pre-selected rational threshold. For example, the first warning can be issued in response to a detection of a 30° threshold being met, the second warning can be issued in response to a 45° or 60° rotational threshold being met, and the third warning can be issued in response to a 60° or 90° rotational threshold being met. It should be appreciated that other rotational thresholds values can be used instead of these exemplary values. - It is contemplated that embodiments of the conveyor apparatus 1 and detection mechanism that is includable within the conveyor apparatus will help to avoid many indirect problems like material spillage, belt snap and belt edge damages. It can also be configured to help in achieving improved running conditions and enhance the operational time of the conveyor apparatus as well as reduce operation and maintenance costs thereby improving productivity. Some embodiments of the conveyor apparatus 1 and conveyor apparatuses utilizing embodiments of the detection mechanism can provide an improved safety system for pipe conveyors, which would also improve operational reliability and improve productivity.
- Further, the
controller 11 can be configured to include an automated training module for pipe conveyor based on feedback from the sensors after thecontroller 11 effects adjustment of different upper frame segments. Such a module could be stored in the controller's non-transitory memory and run via its processor during operation of the conveyor apparatus. Such a configuration can assist in self-correction of belt rotation which would provide a value addition that would greatly enhance the potential for addressing productivity issues associated with pipe conveyors as well as possibly providing similar improvements for some other types of conveyors. - In addition to providing embodiments of a conveyor apparatus 1, a service provider can provide an upgrade kit for incorporation the detection mechanism and convey belt adjustment mechanism into a pre-existing conventional conveyor apparatus. The update kit can include
sensors 31,slideable connection mechanisms 17,pivotal connection mechanisms 19,actuators 17 a, and other structures and components that may be needed to facilitate re-configuration or modification of a pre-existing frame of a conveyor to inclusion and use ofsensors 31,slideable connection mechanisms 17 andpivotal connection mechanisms 19. The upgrade kit can also include thecontroller 11 or software for storing in the memory of a pre-existing controller and installing on a pre-existing controller so thecontroller 11 can be configured to utilize sensor data from sensors, initiate emission of one or more warnings and initiate actuation of any actuators for adjustment of upper frame segments based on thesensor data 31 received fromsensors 31. - It should be appreciated that different embodiments of the conveyor apparatus 1 and different embodiments of the upgrade kit and conveyor control mechanism can utilize different arrangements to meet a particular set of design criteria. For instance, the
sensors 31 can be any type of laser sensor (e.g. visible light, infrared, etc.) or another type of sensor that can be suitable to meet a particular design objective. As another example, theframe 9, the structure of thepivotal connection mechanisms 19, and the structure of theslideable connection mechanisms 17 can include other shaped components, other sized components, or other configurations to meet a particular design objection. As yet another example, the number and arrangement of theactuators 17 a, slideable connection mechanisms included in aframe 9 andpivotal connection mechanisms 19 included in a frame can be any number that may meet a particular set of design criteria. - It should also be appreciated that some components, features, and/or configurations may be described in connection with only one particular embodiment, but these same components, features, and/or configurations can be applied or used with many other embodiments and should be considered applicable to the other embodiments, unless stated otherwise or unless such a component, feature, and/or configuration is technically impossible to use with the other embodiment. Thus, the components, features, and/or configurations of the various embodiments can be combined together in any manner and such combinations are expressly contemplated and disclosed by this statement. Thus, while certain exemplary embodiments of the conveyor apparatus 1, the conveyor control mechanism, and methods of making and using the same have been shown and described above, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously embodied and practiced within the scope of the following claims.
