[0034] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0035] Aiming at the problem that the current finished cigarette box sorting system has a high downtime rate of the robot due to damaged cigarette boxes and cannot be repaired and returned in time, the present invention provides a finished cigarette box sorting automatic control system, which solves the problem that the existing finished cigarette box sorting system has a high downtime rate of the robot due to damaged cigarette boxes and cannot be repaired and returned in time, and can improve the work efficiency of finished cigarette box conveying and sorting, and reduce production costs.

[0036] like Figure 1 and Figure 2 As shown, a finished cigarette box sorting automatic control system includes: a sorting controller, an image acquisition device 4, a sorting conveyor and a position detection sensor 3. A main conveyor line and multiple sub-conveyor lines are set on the finished cigarette box sorting conveyor line, and a sorting station 1 is set at the intersection of each sub-conveyor line and the main conveyor line. The sorting conveyor is set at the sorting station 1 to perform reversing conveying of the finished cigarette box according to requirements. The image acquisition device is set at the detection station of the main conveyor line, and multiple position detection sensors are respectively set at the detection station and the sorting station to detect the arrival of the finished cigarette box. The sorting controller is respectively connected to the image acquisition device, the sorting conveyor and the position detection sensor signal, and controls the image acquisition device to take pictures of the front end surface, the top surface and the rear end surface of the finished cigarette box when the finished cigarette box arrives at the detection station, and then compares the taken cigarette box photos to determine whether the cigarette brand corresponding to the cigarette box and the box body are damaged. When the box body is damaged, the sorting controller controls the sorting conveyor to send the corresponding finished cigarette box from the sorting station to the repair station 2 on the sub-conveyor line, and sends it back to the main conveyor line after the repair is completed to enter the corresponding stacking channel.

[0037] Specifically, the conveyor line is composed of multiple roller machines and sorting conveyors. The cigarette boxes can enter different sorting stations or go along the main conveyor line. When the cigarette box arrives at the inspection station, the image acquisition device takes the front, middle and back photos of the finished cigarette box for image recognition. The front and back photos detect the sealing effect, and the middle photo recognizes the barcode on the cigarette box to determine the cigarette brand. According to the brand, it is automatically distributed to different manipulator code disk channels for coding. The control system compares the front and back photos. If there is no problem, it does not enter the manual repair station, but directly enters the manipulator code disk system through the main conveyor line. If a problem is found, it is sent to the manual repair station. After resealing, it is manually pushed forward. The sorting conveyor drives the finished cigarette box to automatically enter the main conveyor line, and then it is sent back to the main conveyor line. According to the original recognized barcode information, it re-enters the code disk channel for coding.

[0038] The system also includes: a sorting device; the sorting device is arranged on the sorting station, the sorting conveyor is drivingly connected to the sorting device, and controls the sorting device to change the conveying direction according to the control instructions of the sorting controller to convey the finished cigarette boxes to the sorting station or the main conveyor line.

[0039] Furthermore, the sorting device adopts a Mecanum wheel structure. Figure 3 As shown, the sorting device can change direction to transport goods forward, backward, left and right, so that the cigarette box can enter the repair station or enter the main conveyor line from the repair station.

[0040] Furthermore, the position detection sensor adopts a photoelectric switch.

[0041] In actual application, the entire conveyor line is awakened or dormant through the position detection sensor. During production, the entire conveyor line is in standby mode. When the photoelectric switch detects the cigarette box, the conveyor line is started. When the cigarette box leaves the conveyor line, it re-enters the standby mode and is awakened when the cigarette box enters again.

[0042] Furthermore, the inspection station is sequentially provided with a first photoelectric switch, a second photoelectric switch and a third photoelectric switch; when the first photoelectric switch is triggered, the image acquisition device takes a picture of the front end surface of the conveyed finished cigarette box; when the second photoelectric switch is triggered, the image acquisition device takes a picture of the top surface of the conveyed finished cigarette box; when the third photoelectric switch is triggered, the image acquisition device takes a picture of the rear end surface of the conveyed finished cigarette box.

[0043] Furthermore, the repair station is provided with a fourth photoelectric switch and a fifth photoelectric switch in sequence; the sorting controller determines whether the finished cigarette box is to be transported to the repair station or to leave the repair station according to the order of the trigger signals of the fourth photoelectric switch and the fifth photoelectric switch. If it is to leave the repair station, the sorting conveyor is controlled to drive the sorting device to transport the finished cigarette box back to the main conveyor line.

[0044] In actual application, the cigarette box is repaired manually at the repair station, and is pushed manually onto the main conveyor line after the repair is completed. The sorting controller determines whether to enter or leave the repair station based on the detection sequence of the fourth photoelectric switch and the fifth photoelectric switch on the repair station, and automatically starts the two-way conveyor and the sorting device to transport it to the main conveyor line and then into the stacking channel to stack the pallet.

[0045] Furthermore, the image acquisition device includes: an industrial camera and an image recognition processor; the image recognition processor is connected to the industrial camera signal, and the sorting controller is respectively connected to the image recognition processor and the industrial camera signal; the image recognition processor identifies and compares the finished cigarette box photos taken by the industrial camera to identify the brand of the corresponding finished cigarette box and determine whether the box is damaged.

[0046] like Figure 4 As shown, the image acquisition device also includes: a gantry mounting frame 42; the gantry mounting frame 42 is arranged at the inspection station, the industrial camera 41 is arranged on the top beam of the gantry mounting frame 42, and the industrial camera 41 is provided with a following rotation mechanism, which starts focusing and following when the finished cigarette box enters 100 mm in front of the gantry mounting frame.

[0047] Further, the first photoelectric switch is arranged 100 mm in front of the gantry mounting frame, the second photoelectric switch is arranged directly below the gantry mounting frame, and the third photoelectric switch is arranged 100 mm behind the gantry mounting frame.

[0048] In actual application, the first photo is taken when the front end of the cigarette box enters 100mm directly under the high-definition industrial camera, the second photo is taken when the finished cigarette box enters directly under the camera, and the third photo is taken when the rear end of the cigarette box leaves the bottom of the gantry mounting frame and is 100mm away. The three photos are used to identify whether there are any problems and the palletizing station to be entered.

[0049] Furthermore, the sorting controller is a PLC programmable controller or a microprocessor.

[0050] It can be seen that the present invention provides an automatic control system for sorting finished cigarette boxes. The image acquisition device takes pictures of the front face, top face and rear face of the finished cigarette box on the detection station, and then identifies the brand corresponding to the cigarette box and whether the box is damaged. The sorting controller controls the sorting conveyor to transport the corresponding finished cigarette box from the sorting station to the repair station on the sub-conveyor line, and transports it back to the main conveyor line after the repair is completed to enter the corresponding stacking channel. The existing finished cigarette box sorting system solves the problem that the robot has a high downtime rate due to damaged cigarette boxes and cannot be repaired and returned in time, which can improve the work efficiency of finished cigarette box transportation and sorting, and reduce production costs.

[0051] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
