Description

A device for detecting appearance defects of finished cigarettes from a transparent paper packaging machine

technical field

The utility model relates to the technical field of tobacco packaging machine equipment, in particular to a device for detecting appearance defects of finished cigarettes from a packaging machine made of transparent paper.

Background technique

The transparent paper packaging machine outside the strip is mainly the equipment that completes the transparent paper packaging process on the outside of the finished cigarette. The main process of its work is: first, wrap and fold the transparent paper on the transparent paper folding mechanism, and then wrap the packaged cigarettes. The smoke is transported to the secondary heater through the conveying mechanism for secondary heating. Finally, the finished cigarette after secondary heating and beautification is output to the downstream equipment for boxing and other operations through the conveying mechanism. Among them, in the process of wrapping and folding transparent paper, since the transparent paper itself is thin and needs to be conveyed through multi-stage transmission, drift, dislocation and frictional static electricity will inevitably occur during the process, resulting in strips after packaging. Misalignment of the outer transparent paper, poor folding and other defects in the appearance and packaging quality of the strips may cause the products to flow into the downstream equipment, resulting in unqualified products, or cause congestion and dislocation of the cigarettes, and even cause the equipment to shut down, which not only causes product waste, but also extremely The earth affects production efficiency.

Detailed ways

As shown in Figure 1, the utility model includes the outer transparent paper packaging machine including a transparent paper folding mechanism 1 and a secondary heating mechanism 2, and a cigarette conveying mechanism is arranged between the transparent paper folding mechanism 1 and the secondary heating mechanism 2. The smoke conveying mechanism includes a conveying channel 3 and a conveying motor (not shown in the figure), and the two sides of the conveying channel 3 are respectively provided with a front wall panel 4 and a rear wall panel 5; Photoelectric sensors, each group of through-beam photoelectric sensors include optical fiber transmitters 6, optical fiber receivers 7 and amplifiers (not marked on the figure), optical fiber transmitters 6 are located on the inner wall of the front wall panel 4 and are slightly Higher than the upper end surface of the cigarette 8 to be detected, the optical fiber receiving head 7 is arranged on the inner wall of the rear wall panel 5 and correspondingly arranged with the corresponding optical fiber receiving head 7, and the output end of the optical fiber receiving head 7 is connected to the light guide of the amplifier The input port, the optical fiber output port of the amplifier is connected to the input end of the optical fiber launch head 6;

The utility model also includes a central processor, the amplified signal output end of the amplifier is connected to the detection signal input end of the central processor, and the control end of the central processor is connected to the controlled end of the conveying motor.

In order to better understand the utility model, the technical solutions of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, the cigarette rod conveying mechanism between the transparent paper folding mechanism 1 and the secondary heating mechanism 2 is sequentially set as the second station, the third station and the fourth station from left to right. The number of through-beam photoelectric sensors in the example is preferably two groups, wherein one group of through-beam photoelectric sensors is arranged at a position close to the transparent paper folding mechanism 1, that is, at the second station, and the other group of photoelectric sensors is arranged at a position close to the transparent paper folding mechanism 1. The position of the secondary heating mechanism 2 is set at the fourth station.

The optical fiber transmitting head 6 and the optical fiber receiving head 7 preferably adopt a pair of detection probes whose model is FU-77V, the amplifier preferably adopts the optical fiber amplifier of models such as E3X-DA11-S, and the central processing unit preferably adopts Siemens series CPU222PLC and other models PLC. Since the outer wall of the detection probe of FU-77V has threads, it is preferable to set up a group of threaded holes matched with the detection probe of FU-77V on the front wall plate 4 and the rear wall plate 5 of the second station. Pass the optical fiber emitting head 6 through the threaded hole provided on the front wallboard 4, and pass the optical fiber receiving head 7 through the threaded hole provided on the rear wallboard 5, so that the optical fiber emitting head 6 is fixedly installed on the front wallboard 4 Above, the optical fiber receiving head 7 is fixedly installed on the rear wallboard 5, and the probes of the optical fiber emitting head 6 and the optical fiber receiving head 7 correspond. In the same way, another group of optical fiber emitting head 6 and optical fiber receiving head 7 are fixedly installed on the fourth station. The threaded hole set by the second station is preferably 3 mm from the upper end surface of the rod 8 in the conveying channel 3. This distance can detect defects in the appearance of the rod 8 more accurately. The threaded hole set by the fourth station is 8 mm away from the rod The distance between the upper end faces is preferably set to 3 mm or slightly less than 3 mm.

After the cigarette 8 is packaged, it enters the conveying passage 3 from the transparent paper folding mechanism 1, and the conveying motor drives the conveying passage 3 to move, and the cigarette 8 is conveyed to the secondary heating mechanism 2 for heating and making it look beautiful. Since the signal of the optical fiber probe is an optical fiber signal, it cannot be directly sent to the PLC. Therefore, the optical fiber signal of the optical fiber receiving head 7 is converted into an electrical signal by the amplifier and then sent to the PLC. When the appearance of the cigarette 8 is normal, the signal between the optical fiber emitting head 6 and the optical fiber receiving head 7 is connected, and the through-beam photoelectric sensor sends a low-level signal to the PLC; when the transparent paper or box after packaging is deformed , it will inevitably cause the deformation of the rod 8. When the deformed cigarette 8 passes through the second station, the signal between the optical fiber emitting head 6 and the optical fiber receiving head 7 set at the second station is cut off. The photoelectric sensor sends a high level to the PLC, and the PLC judges that the appearance of the cigarette 8 is abnormal and controls the conveying motor to stop. Since the second station is still a certain distance from the secondary heating mechanism 2, the timely shutdown of the conveying motor effectively avoids the abnormal appearance When the smoke 8 enters the secondary heating mechanism, the smoke is squeezed, which avoids the waste of materials and equipment damage; The photoelectric sensor detects the cigarette 8 again, further improving the reliability and accuracy of the utility model, and ensuring the stable operation of the production line of the transparent paper packaging machine outside the strip.
