Detailed description of the invention
The scheme of what the embodiment of the present invention provided prevent belt deviation, solving in the correlation technique introduced in background technology, needing often to change edger roll and deviation switch, the problem that the cost brought increases and maintenance workload is large to prevent belt deviation.
Technical scheme in the embodiment of the present invention is understood better in order to make those skilled in the art person, and enable the above-mentioned purpose of the embodiment of the present invention, feature and advantage become apparent more, below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is described in further detail.
Please refer to accompanying drawing 1, Fig. 1 is the schematic flow sheet that the first shown in the present invention one exemplary embodiment prevents the method for belt deviation.This prevents the method for belt deviation, for belt conveyor, as shown in Figure 4, this belt conveyor comprises two cylinders 1 be arranged side by side, and is wound in the belt 3 between two cylinders 1, and the quantity of cylinder 1 is at least two, as shown in Figure 1, this prevents the method for belt deviation from comprising the steps:
S110: be arranged at belt both sides of the edge line and send photosignal with holding between line and near the photoelectric switch group of this cylinder to this belt place plane to these at least two cylinders.
Photoelectric switch group can comprise multiple, please refer to Fig. 4 and Fig. 5, by photoelectric switch group being arranged at belt both sides of the edge line to two cylinder with between end line, can belt to the either end sideslip at cylinder two ends and shading light electric signal time, each group photoelectric switch can sense the belt of sideslip exactly, can reflect the position of belt deviation further exactly.Meanwhile, due to when belt deviation, belt is large relative to the sideslip degree of belt middle to the sideslip degree of cylinder end, therefore, photoelectric switch is arranged at the position near two cylinders, belt deviation can be detected delicately, thus the sideslip degree of belt can be detected accurately.Wherein, above-mentioned belt both sides refer to the both sides that the long limit of belt is corresponding, namely away from the both sides of cylinder; The two ends of cylinder refer to the two ends that cylinder is corresponding with belt both sides.
S120: when photoelectric switch group senses that the belt of sideslip blocks described photosignal, this photoelectric switch group sends offset signals to warning shutdown device, reports to the police to make above-mentioned warning shutdown device carry out or closes down operation to the belt execution of sideslip.
When photoelectric switch group senses the belt shading light electric signal of sideslip, namely photoelectric switch group can sense belt deviation, thus sending offset signals to the warning shutdown device be electrically connected with this photoelectric switch group immediately, warning shutdown device carries out reporting to the police or performing the belt of sideslip closing down operation according to the offset signals that photoelectric switch group sends.Concrete, according to the grade of the offset signals that photoelectric switch sends, judge that needing to send alerting signal to operating personal still closes down belt conveyor.Wherein, photoelectric switch group is collided in order to prevent belt, photoelectric switch group arrange position not with belt place planes overlapping, after research and testing, between 50mm to 100mm, (comprise end value) the most suitable for light source issuing side to the vertical distance of belt place plane of photoelectric switch group.
Photosignal (as: infrared signal) is sent with holding between line and near the photoelectric switch group of cylinder to belt place plane by being arranged at belt both sides of the edge line to two cylinder, when belt laterally (namely to one end of cylinder) sideslip time, belt will block this photosignal, because photosignal is blocked, photoelectric switch group will send offset signals to warning shutdown device; After warning shutdown device receives this offset signals, according to the rank of offset signals, select to carry out reporting to the police or closing down.The device of what the present embodiment provided prevent belt deviation, photoelectric switch group is set by sending photosignal to respond to belt whether sideslip, due to belt deviation away from home position during shading light electric signal photoelectric switch group can send offset signals, not direct with the photoelectric switch group contact-impact of belt in this process, thus make photoelectric switch group be not easy to damage, and then reduce the turnover rate of switch, reduce the cost and work capacity that prevent belt deviation from bringing.
Due to the direction of belt deviation and sideslip degree uncertain, therefore in order to determine direction and the degree of belt deviation, as shown in Figure 4 and Figure 5, photoelectric switch group needs to arrange multiple, and each photoelectric switch group comprises: the one-level photoelectric switch be arranged in order to described at least two cylinders with one end line from described belt side edge line and secondary light electric switch; Described warning shutdown device comprises alarm signal generator and is connected to the pull switch on the power lead of described belt conveyor; As shown in Figure 2, Fig. 2 is the schematic flow sheet that the second shown in the present invention one exemplary embodiment prevents the method for belt deviation to concrete method, and this prevents the method for belt deviation from also comprising:
S210: what judge that the belt of sideslip blocks is the photosignal that the photosignal that sends of one-level photoelectric switch or secondary light electric switch send; If what block is the photosignal that one-level photoelectric switch sends, then perform step S220; If what block is the photosignal that secondary light electric switch sends, then perform step S230.
Because photoelectric switch group comprises the one-level photoelectric switch and secondary light electric switch be arranged in order to described at least two cylinders with one end line from described belt side edge line, and belt deviation is from inside to outside, namely by belt side edge line to direction sideslip with one end line of described at least two cylinders, therefore, one-level photoelectric switch can detect that the sideslip degree that belt is comparatively slight, secondary light electric switch can detect the sideslip degree that belt is comparatively serious.
S220: if one-level photoelectric switch senses the photosignal that the belt of sideslip blocks one-level photoelectric switch and sends, this one-level photoelectric switch sends one-level offset signals to above-mentioned alarm signal generator.
If one-level photoelectric switch senses the photosignal that the belt of sideslip blocks one-level photoelectric switch and sends, illustrate that slight sideslip appears in belt, now, one-level photoelectric switch sends one-level offset signals to alarm signal generator, signal generator can be made to send alerting signal, as the signal such as sound and light alarm, image alarm, thus associative operation personnel are made promptly to carry out judging to the belt of this sideslip and overhaul.Because belt only touches the photosignal that one-level photoelectric switch sends, directly do not contact with one-level photoelectric switch, therefore one-level photoelectric switch can not be worn, and reduces cost and work capacity that switch changes.
S240: this alarm signal generator sends alerting signal.
Alarm signal generator can send the alerting signal of the form such as sound and light alarm, image alarm, thus reminds associative operation personnel rapidly the belt of this sideslip to be carried out to the judgement of sideslip degree and safeguards.
S230: when secondary light electric switch senses that the belt of sideslip blocks the photosignal that secondary light electric switch sends, this secondary light electric switch sends secondary offset signals to above-mentioned pull switch, closes down belt conveyor to make this pull switch.
Secondary light electric switch is arranged near two cylinders with one end line, namely the position arranged is more outer compared with one-level photoelectric switch, therefore when secondary light electric switch sends secondary offset signals, illustrate that the degree of belt deviation is comparatively serious, belt has sheltered from the photosignal that secondary light electric switch sends, now, secondary light electric switch sends secondary offset signals to connected pull switch, thus make pull switch close down belt conveyor in time, prevent because larger Peril Incident appears in belt deviation.
S250: pull switch closes down belt conveyor.
When pull switch receives secondary offset signals, belt conveyor can be closed down in time, thus the Peril Incident because the excessive sideslip of belt brings can be prevented.
Because the belt of sideslip only contacts with the photosignal that one-level photoelectric switch or secondary light electric switch send, the belt of sideslip can't collide one-level photoelectric switch and secondary light electric switch, because this reducing degree of wear and the replacement frequency of one-level photoelectric switch and secondary light electric switch, further reduce operating personal to the work capacity of photoelectric switch and maintenance cost.
Because operating personal distance belt conveyor may be far away, the degree of belt deviation can not be recognized in time, can not make when belt deviation and reacting timely, therefore, in order to prevent above-mentioned situation, as shown in Figure 3, Fig. 3 is the schematic flow sheet that the third shown in the present invention one exemplary embodiment prevents the method for belt deviation, and this prevents the method for belt deviation from also comprising the steps:
S310: when described photoelectric switch group senses that the described belt of sideslip blocks described photosignal, described photoelectric switch group sends offset signals to the processing terminal be electrically connected with described photoelectric switch group;
Offset signals is sent to processing terminal by photoelectric switch group, processing terminal can be made to understand in time and point out the situation of belt deviation to associative operation personnel, as belt deviation degree etc., wherein, processing terminal can be the terminals such as smart mobile phone, panel computer, notebook PC, desk-top server.
S320: processing terminal is according to described offset signals process belt deviation situation, and/or prompting associative operation personnel process described belt deviation situation.
Processing terminal can be resolved offset signals, thus analyzes the degree of belt deviation, is processed this offset signals by the processing mode prestored of inside, and then performs corresponding operation to belt conveyor, closes down operation etc. as performed.And/or the situation of prompting associative operation personnel belt deviation, make associative operation personnel carry out respective handling according to situation (as the sideslip degree) belt to sideslip of belt deviation.
