[0002] In cigarette production, stacking equipment is set up in the storage area of ​​the finished product high-bay warehouse to stack the finished cigarette pieces. The finished cigarette pieces are stacked in a flat or upright position. For flat cigarette pieces, they are transported to the grabbing station through the sorting conveyor chain machine. For upright cigarette pieces, when they arrive at the grabbing station, a flipping mechanism is used to flip the flat cigarette pieces on the sorting conveyor line into upright cigarette pieces, forming 2 or 3 upright cigarette pieces at the grabbing station. Then the robot automatically adjusts the clamp width suitable for the size of the cigarette piece according to the brand and stack type of the cigarette piece at the station, enters the station to grab the cigarette piece, and transports it to the designated position of the corresponding pallet of the storage conveyor chain machine for stacking. In daily operations, cigarette jams, channel equipment failures, barcode recognition errors, etc. will all cause sorting conveyor chain machine failures. After the relevant failures are handled, in order for the robot to correctly grab the number of cigarette pieces, it is necessary to manually check the number of cigarette pieces in each storage channel in detail.

[0031] In order to more clearly illustrate the specific embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below.

[0032] Figure 1 The present invention is a schematic diagram of a cigarette piece checking system of a stacking device provided by the present invention. DETAILED DESCRIPTION

[0033] 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.

[0034] In view of the problem that the number of cigarettes on the conveyor chain machine is time-consuming, labor-intensive and inaccurate in current cigarette production, the present invention provides a cigarette number checking system for stacking equipment to solve the problem that the number of cigarettes is time-consuming and inefficient when the finished cigarettes are put into storage in the existing finished product high-bay warehouse, and the cigarettes are easily piled up and affect the storage efficiency. It can improve the work efficiency of storage, reduce the workload of manual operation, and improve the intelligence of the cigarette production line.

[0035] like Figure 1As shown, a cigarette piece verification system for stacking equipment includes: a photoelectric switch, a controller, a camera and an on-site industrial computer. A plurality of the photoelectric switches are arranged on different areas of the conveyor chain machine, and are used to detect the number of cigarette pieces flowing through in sections. The controller is connected to the photoelectric switch signals, and the controller determines the conveying state and number of cigarette pieces on the conveyor chain machine according to the corresponding number of cigarette pieces detected by the plurality of photoelectric switches. The controller is connected to the on-site industrial computer signals, and the on-site industrial computer is connected to the camera signals, and the camera is used to take real-time video of the conveying channel of the conveyor chain machine. The on-site industrial computer is used to display the video, and the on-site industrial computer also displays the product information and quantity statistics of the cigarette pieces flowing through the conveyor chain machine. When the number of cigarette pieces detected by the plurality of the photoelectric switches is different, the controller reports an error alarm of the number of cigarette pieces, and the on-site industrial computer displays the alarm information and stops the conveyor chain machine.

[0036] In actual applications, it is not easy for human eyes to see clearly from a distance when facing the moving cigarettes entering the warehouse in each channel. By using a high-definition network camera to include the real-time status of the cigarettes in each channel into the lens focus range for collection, the role of human "eyes" is realized. According to a complete set of stacking equipment (1 robot, 4 sorting conveyor chains, and 4 warehouse conveyor chains) as a unit, a camera is installed and fixed at a high position in the middle of these four channels to implement on-site image monitoring, and the monitoring range is clear and controllable. The controller uses the camera to shoot the conveying channel of the conveyor chain machine in real time, and the on-site industrial computer receives the real-time video sent by the controller and displays it. If the number of cigarettes collected in different sections is different, it means that the cigarettes have not been transmitted on the conveyor chain machine, or the restart caused by a fault causes repeated counting. The operator may check the real-time video on the on-site industrial computer to confirm the specific number of cigarettes, and then restart the equipment. The system can improve the efficiency of warehousing, reduce the workload of manual operation, and improve the intelligence of the cigarette production line.

[0037] The system also includes: a network router; the controller is connected to the network router, the on-site industrial computer is connected to the network router, and the controller forms a local area network with the on-site industrial computer through the network router.

[0038] Specifically, in order to allow operation and maintenance personnel in different locations to understand, share, and communicate in a timely manner, router networking technology is used as a support to transmit image information in a timely manner, thus realizing the function of long-distance video monitoring. Because network cameras, routers, and computers all have network functions, to realize the networking function, they must be set up in the same local area network to achieve a safe and reliable connection.

[0039] The system also includes: a central control room terminal; the central control room terminal is connected to the network router network, and the central control room terminal is connected to the on-site industrial computer network through the network router; the central control room terminal is used to perform video monitoring on multiple storage channels.

[0040] Furthermore, the central control room terminal runs a remote management APP, which displays multiple storage channels in multiple screens or on a single screen, and displays and verifies the number of cigarette cases in each storage channel. When there is an error in the number of cigarette cases, the central control room terminal remotely controls the on-site industrial computer through the remote management APP and corrects the number of cigarette cases.

[0041] Specifically, the terminal in the central control room receives multiple camera images from the on-site industrial computer through a network router. In terms of software programming planning, the screen area is divided by program module technology, and window controls are added. At the same time, the network configuration file is automatically called in the program to fully realize automatic monitoring. In this way, all channels in the storage area can be switched in turn, and functions such as multi-screen column display, single-screen independent display, and local area magnification can be realized according to actual production needs in the software interface mode. The program code generates an EXE executable file and is installed on two terminal computers at the storage site and the central control room respectively. Remote monitoring can be implemented simultaneously at the storage site and the central control room to achieve distributed layout, and the local area magnification function can be used to complete the remote verification of the number of cigarettes on site. With the wincc interface that comes with the original system, data modification operations can be easily completed.

[0042] The system also includes: an alarm device; the alarm device is connected to the controller by signal, and the controller controls the alarm device to alarm when the number of cigarette pieces is wrong.

[0043] Furthermore, the alarm device is at least any one of the following: an alarm indicator light, an alarm, a buzzer and a loudspeaker.

[0044] The system also includes: a barcode scanner; the barcode scanner is arranged at the storage channel, the barcode scanner is connected to the on-site industrial computer signal, the barcode scanner is used to scan the barcode of the cigarette box to identify the brand of the cigarette entering the warehouse and collect product information; the on-site industrial computer is also used to display the brand and product information of the cigarette entering the warehouse.

[0045] The system also includes: a manipulator; the manipulator is connected to the on-site industrial control computer by signal, and the on-site industrial control computer grabs and stacks the cigarette pieces entering the workstation according to the set cigarette piece brand and stack type.

[0046] In actual applications, flat cigarette pieces are transported to the grabbing station through the sorting conveyor chain machine. When the upright cigarette pieces arrive at the grabbing station, the flat cigarette pieces on the sorting conveyor line are first turned over by the robot into upright cigarette pieces.

[0047] The system also includes: a weighing device; the weighing device is connected to the on-site industrial computer by signal, the weighing device is used to weigh the cigarette pieces flowing through and report the weight of the cigarette pieces to the on-site industrial computer; the on-site industrial computer reports an abnormal weight alarm when the weight of the cigarette pieces exceeds a set weight range.

[0048] In actual applications, the brand and quality of the cigarettes can also be ensured by checking the weight of the cigarettes. If the weight of the cigarette is greater than the set upper weight limit or less than the set lower weight limit, it means that the cigarette may be abnormal and needs manual inspection.

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

[0050] It can be seen that the present invention provides a cigarette piece verification system for stacking equipment, which uses a controller to verify the number of cigarette pieces detected by multiple photoelectric switches set in different areas of the conveyor chain machine, and uses a camera to take real-time video of the conveying channel of the conveyor chain machine, and the on-site industrial control computer displays and counts the number. It solves the problem that the number of cigarette pieces is time-consuming and inefficient when the finished cigarette pieces are put into storage in the existing finished product high-bay warehouse, which easily causes the accumulation of cigarette pieces and affects the storage efficiency. It can improve the work efficiency of storage, reduce the workload of operations, and improve the intelligence of the cigarette production line.
