[0047] Device installation:

[0048] Connection of the collection machine with the PLC (S7-200): First, place the YP11.81L transverse collection machine at the pre-planned position on the tobacco production line, ensuring that it is stably and horizontally installed. Use a dedicated signal transmission cable, one end of which is accurately connected to the start signal output port of the transverse collection machine, and the other end is connected to the I0.0 port of the S7-200 PLC, ensuring that the connection is tight and has no looseness. At the same time, use hard-wired connection to connect the shunt device with the S7-200 PLC according to the designed electrical connection diagram. The connection points of each wire are firmly crimped or welded, and good insulation protection is provided to prevent short circuit and leakage.

[0049] Photoelectric switch installation: At a position 5-10 cm above the main input channel, use the matching installation support 5 to accurately install the one-way photoelectric switch 901, ensuring that its transmitting end and receiving end are on the same horizontal line and aligned with the running track of the cigarette rod 30. Use a shielded cable to connect its signal output end with the signal collection port of the S7-200 PLC, and the shielded layer of the cable should be reliably grounded to effectively reduce external electromagnetic interference. Similarly, install the two-way photoelectric switch 902 at a position two-thirds away from the outlet of the main input channel, and install the reflective photoelectric switch 903 at a position 3-5 cm below the entrance of the shunt input channel, and connect the corresponding signal transmission lines.

[0050] Electromagnetic valve and rodless cylinder 6 installation: two-position five-way electromagnetic reversing valve is connected with S7-200 PLC through control cable, and wiring is ensured to be correct. Rodless cylinder 6 is installed between 2 and 3 of the collecting machine, and a wear-resistant cigarette pushing plate 7 is installed on the piston of the rodless cylinder 6. The cigarette pushing plate 7 is made of wear-resistant engineering plastic, and the surface is treated specially to reduce the wear of the cigarette 30.

[0052] Normal operation process: YP11.81L transverse collecting machine is started, the starting signal is connected to I0.0 port of S7-200 PLC, and the shunt device is triggered to start. During the cigarette 30 collecting process, the first photoelectric switch 901, the second photoelectric switch 902 and the third photoelectric switch 903 detect the state of the cigarette 30 in real time. When the cigarette 30 shunt condition is met (the first photoelectric switch 901 and the second photoelectric switch 902 installed on the 2 channel detect the cigarette 30 at the same time, and the third photoelectric switch 903 installed on the 3 channel does not detect the cigarette 30), S7-200 PLC outputs a signal to control the electromagnetic valve to drive the rodless cylinder 6 to act, and the cigarette 30 is shunted from the 2 channel to the 3 channel of the collecting machine through the cigarette pushing plate 7 installed on the cylinder 6.
