Fig. 1 is a schematic structural view of some embodiments of a stretch detection system of a drag conveying apparatus of the present utility model, which includes a plurality of subjects 110, a detector 120, an encoder 130, and a control circuit 140. The chain plate conveying device is used for conveying cigarettes.
A plurality of objects 110 are disposed on the flight of the flight conveying apparatus.
As shown in fig. 2, the plurality of objects to be inspected 110 includes a plurality of photo-electric responders including a first photo-electric responder 40 and one or more second photo-electric responders 41 (e.g. 41_1, 41_2, … 41_n in the drawing), wherein the first photo-electric responder 40 is used for positioning the start position of the link plate.
In some embodiments, the first photo-responder 40 comprises at least two reflective strips and the second photo-responder 41 comprises one reflective strip. For example, the start position of the stretch detection of the link plate is determined by providing two reflection strips in close positions. The first photo-electric responders 40 and the plurality of second photo-electric responders 41 are arranged on the chain plate 51 of the chain plate conveying device at uniform intervals, dividing the chain plate 51 into a plurality of sections. The number of the second photo-responders 41 is determined according to the length of the link plate 51, and the more the second photo-responders 41, the more accurate the subsequent detection, but generally not more than 6 in view of cost and operation of the link plate.

For example, if the reflective photocell 31 detects two reflective strips 40 within a predetermined time, the encoder 130 initializes the encoded value and records the encoded value X0. When the reflective photocell 31 detects the first pulse signal, the code value x1=the current code value-X0 is recorded, when the reflective photocell 31 detects the second pulse signal, the code value x2=the current code value-X0 is recorded, when the reflective photocell 31 detects the nth pulse signal, the code value xn=the current code value-X0 is recorded, after the data of the set N is recorded, the initialized mark of the chain plate stretching detection is reset, and the whole chain plate stretching detection initialization process is completed.

If the information received by the first input end of the comparator is greater than the information received by the second input end, the output of the comparator is 1, namely that the chain plate of the section is possibly abnormal is indicated; if the information received by the first input end of the comparator is equal to the information received by the second input end, the output of the comparator is 0, which indicates that the chain plate of the section is not abnormal.
In some embodiments, the control circuit 140 may also be a specific hardware device composed of a PLC, an integrated circuit, related components, and the like.
Under the condition that the chain plate is abnormal, alarm information is output through the alarm, so that operators can confirm and process abnormal conditions in time.
In the embodiment, the chain plate stretching tension detection device is simple in principle, simple in structure and good in reliability, the chain plate motor is skillfully used for connecting the encoder and the reflecting photoelectric tube to detect the chain plate stretching tension in real time, meanwhile, the logistics conveying efficiency is improved, and the hidden danger of chain plate blocking caused by too loose chain plate tension and too tight chain plate tension fracture faults is reduced. In addition, the tensile detection system is arranged at the end position of the chain plate machine, which is easy to operate and install, and the tensile detection system has lighter weight, simple installation flow and no operation.
In other embodiments of the present utility model, an apparatus is also claimed that includes a flight conveying apparatus and the stretch detection system of the above embodiments.

For example, the actual code value of each area segment when the reflective photocell detects the initial pulse signal and the segmented pulse signal is recorded. And determining the actual stretching distance between the current position of the detected object and the starting position of the chain plate by comparing the difference value of the current coding value of the detected object and the coding value corresponding to the starting position of the chain plate.
In step 320, the actual stretch distance is compared with an initial stretch distance between a position of the corresponding inspected object to a starting position of the link plate when the link plate conveying device is not in fault, and a stretch deviation of each segment of the link plate is determined.
In some embodiments, the initial stretch distance and the actual stretch distance are represented by codes.
For example, link plate stretch is measured by comparing the deviation between the historical code and the current real-time code value.
In step 330, it is determined whether to perform a link plate stretch abnormality warning according to the stretch deviation.
In some embodiments, the anomaly early warning is performed when the stretch deviation of any one of the link plates is greater than a threshold value.

For example, if at least two pulse signals are detected within a preset time, it is determined that the object located at the start position of the link plate is detected.
As shown in fig. 5, since the reflective strips are arranged at relatively uniform intervals on the link plate 51, the number of pulses is set according to the number of objects to be inspected at the home position of the non-link plate.

And after the abnormal coded value early warning is confirmed and processed, the coded value of the chain plate starts to be monitored and detected again in real time.
In step 630, an initial pulse signal is detected.
In step 640, a non-initial pulse signal is detected.
In step 650, it is determined whether the difference between the current encoded value and the initial encoded value corresponding to the non-initial pulse signal is greater than or equal to the stretching deviation threshold, if yes, step 660 is performed, otherwise, step 670 is performed.
In step 660, it is determined whether the stretching of the link plate exceeds the pre-warning value, and if yes, the flow is ended, otherwise, step 620 is continued.
And after the abnormal coded value early warning is confirmed and processed, the coded value of the chain plate starts to be monitored and detected again in real time.
In step 670, it is determined whether the non-initial pulse signal is an nth pulse signal, if yes, step 620 is performed continuously, otherwise, step 640 is performed.
