detailed description

The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but they are not limitations to the technical solution of the present invention, and any changes made based on the teachings of the present invention all fall within the scope of protection of the present invention.

Example 1

As shown in Figure 1, a cigarette rod running skew and deformed tobacco rod detection device, its basic composition includes: tobacco rod skew detection optical fiber 4 and cigarette rod skew detection amplifier 5, DC power supply, photoelectric coupler, single circuit breaker and The PLC controller, optical fiber and amplifier are connected to the electric control system of the original machine YP13 case packing and sealing machine through the PLC controller and photoelectric coupler. The user can detect defects such as skewed running of the tobacco rod and deformation of the tobacco rod by adjusting the sensitivity of the amplifier. And automatically stop the cigarette rod conveyor belt at the entrance of YP13 case packing and sealing machine.

As shown in Figure 2, the five tobacco rod skew detection optical fibers 4 and the tobacco rod skew detection amplifier 5 are installed on the tobacco rod conveyor belt 2 at the entrance of the YP13 box packing and sealing machine 1 through the tobacco rod skew detection mounting bracket 3, and the amplifier is installed On the base of the YP13 box packing and sealing machine, the distance between the tobacco rod skew detection optical fiber 4 and the tobacco rod is 10-30mm, and the five tobacco rod skew detection optical fibers 4 are installed at equal intervals (the length of the tobacco rod is 270mm, and the width of the tobacco rod conveyor belt is 280mm, the width of the tobacco stick is 88mm, and the distance between the optical fibers is less than 50mm), to ensure that the skew of the tobacco stick can be detected under any circumstances, by adjusting the sensitivity of the skew detection amplifier 5 and the distance between the skew detection optical fiber 4 and the smoke stick It is guaranteed that when there is a cigarette rod passing by, the skew detection amplifier 5 of the cigarette rod outputs a high level, and when no smoke rod passes through, the output is a low level, and because through adjustment, the detection distance of the skew detection amplifier 5 of the cigarette rod can be adjusted to about 35mm, when When the tobacco rod is severely deformed, its reflective surface changes, and the tobacco rod skew detection amplifier 5 cannot detect the effective tobacco rod, which can be regarded as skewed; When deforming, its five smoke bar skew detection amplifiers 5 all output high level or all output low level (there is a high level when there is a smoke bar, and it is a low level when there is no smoke bar), through programming, the PLC controller They are all considered normal. At any time, as long as there is more than one but less than five tobacco stick skew detection amplifiers 5 whose state is opposite to the rest, the PLC controller judges that the tobacco stick is skewed or deformed, and its output high level is sent to the original machine YP13 for packaging. Box machine controller, YP13 controller output low level, disconnect its inlet tobacco rod conveyor belt contactor, stop the conveyor belt running, at this time the operator will take away the skewed or deformed tobacco rods, click YP13 box packing and sealing machine 1 to start switch, the YP13 controller outputs a high level to control the tobacco rod conveyor belt contactor at the entrance of the box packing and sealing machine, and the tobacco rod conveyor belt 2 starts to run, thereby completing the detection of skewed and deformed tobacco rods.
