[0032] The automatic paper tray replacement machine provided in the embodiment of the present invention can better realize the replacement of paper trays and effectively ensure the supply of cigarette paper, tipping paper or filter rod forming paper in the cigarette making unit and the filter rod forming unit.

[0033] Specifically, the splicing device includes a flexible splicing component 12 and a punch 11. During splicing, the flexible splicing component and the punch cooperate with each other to achieve the splicing of the new paper disc belt and the old paper disc belt.

[0034] Furthermore, the control system includes a Siemens main controller, a Siemens extended controller, a Siemens driver, and a Festo remote I / O module. The Siemens extended controller and the Festo remote I / O module are respectively communicated with the Siemens main controller; the Siemens extended controller controls the servo motors of the above-mentioned devices through the Siemens driver; the Festo remote I / O module is used to process information from each sensor, control each solenoid valve, and control the motor of the negative pressure fan.

[0035] Specifically, the Siemens extended controller is used to control the motor of the splicing device, the motor of the front winding device, the motor of the rear winding device, the motor of the disk loading device, the motor of the paper disk unsealing device, the motor of the lifting device, the motor of the circulating disk device 1, the motor of the new paper disk chuck core shaft 13 and the motor of the old paper disk chuck core shaft 8. It can be preferred that the above motors are Siemens AC servo motors. The use of AC servo drive not only realizes the constant tension supply of the online paper disk belt, but also can adjust the supply tension value of the online paper disk belt in real time according to production needs.

[0036] Preferably, the Siemens main controller is a SIMOTION D455-2 controller, which is a motion controller with integrated PLC operation function, and is used as an upper controller of the control system; the Siemens expansion controller is a CU320-2 controller, and the Siemens drive is a SINAMICS S120 drive.

[0037] Specifically, the sensor information processed by the Festo remote I / O module includes: material trolley arrival information, paper disc tape remaining amount detection on the clamping plate, upper limit position information of the disc loading device, lower limit position information of the disc loading device, initial position information of the paper picking knife, negative pressure signal of the paper picking knife, motor return information of the front end winding device, motor extension information of the front end winding device, paper tape breakage detection information, total air pressure detection information, paper disc loading arrival information, old paper disc tape existence information, new paper disc tape existence information, motor return information of the rear end winding device, motor extension information of the rear end winding device and opening information of the feeding rubber wheel.

[0038] Furthermore, the solenoid valves controlled by the Festo remote I / O module include: a motor return solenoid valve of the rear end winding device, a motor extension solenoid valve of the rear end winding device, a chuck opening solenoid valve, a chuck clamping solenoid valve, a chuck secondary air pressure solenoid valve, a paper pick-up knife negative pressure solenoid valve, an auxiliary material blowing solenoid valve, a circulation disk air source solenoid valve, a material trolley release solenoid valve, a material trolley locking solenoid valve, a paper feeding rubber wheel return solenoid valve, a feeding rubber wheel clamping solenoid valve, a paper pressing rod return solenoid valve, a paper pressing rod clamping solenoid valve, a front end winding device motor return solenoid valve, a front end winding device motor extension solenoid valve, a rear end paper guide groove return solenoid valve, a rear end paper guide groove extension solenoid valve and two spare solenoid valves.

[0039] It can be understood that the tray loading device has the above-mentioned material trolley; when installing, the new paper tray and the old paper tray are clamped on their respective clamping plates and fixed; when disassembling, the clamping plates release the new paper tray and the old paper tray. The new paper tray clamping plate spindle motor and the old paper tray clamping plate spindle motor are both installed on the circulation plate and rotate with the circulation plate. The drivers of the two spindle motors can be set in the sub-electric control cabinet, the driver of the AC servo motor and the main controller and the expansion controller can be set in the main electric control cabinet, and the DC bus and control bus of the sub-electric control cabinet are connected to the main electric control cabinet through slip rings.

[0040] Specifically, the Festo remote I / O module controls the motor of the negative pressure fan via an external 24V DC contactor.

[0041] Preferably, the motor of the negative pressure fan is a Siemens AC asynchronous motor. It is understandable that the negative pressure fan can provide the adsorption force required for each paper tray to complete the process flow. The upper industrial computer can exchange data with the main controller SIMOTION D455-2 in the form of industrial Ethernet. The upper industrial computer can display and collect various status information of the equipment, and can control equipment debugging and production activities.

[0042] Furthermore, the control system of the paper tray automatic changer also includes a circulating tray encoder, which is used to collect real-time position information of the circulating tray, and then transmit it to the Siemens main controller SIMOTION D455-2 through the PROFINET bus to achieve precise driving of the circulating tray.

[0043] Specifically, the Siemens expansion controller is connected to the Siemens main controller via the Siemens DRIVE-CLIQ bus; the Festo remote I / O module is connected to the Siemens main controller via the PROFINET bus. In one embodiment, the Siemens main controller and the Siemens expansion controller coordinate three dual-channel and three single-channel SINAMICS S120 drivers via the DRIVE-CLIQ bus to control the above-mentioned Siemens AC servo motors.

[0044] The general working process of the automatic paper tray changing machine of the present invention is:

[0045] When the diameter of the old paper disc reaches the splicing diameter, the new paper disc is wound on the winding shaft of the front winding device, so the new paper disc is accelerated by the front winding device.

[0046] When the speed of the new paper disc belt is accelerated to the same linear speed as the old paper disc belt, the flexible splicing component of the splicing device and the punch start to rotate in opposite directions, and the flexible splicing component of the splicing device contacts and starts to mesh with the punch, so that the front end of the new paper disc belt breaks; at the moment when the flexible splicing component of the splicing device ends meshing with the punch, the old paper disc belt also breaks, and at the same time, the rear-end winding device completes the winding of the old paper disc belt, that is, the splicing of the new paper disc belt and the old paper disc belt is realized;

[0047] Then, the old paper disc is removed from the chuck core shaft of the old paper disc, the lifting device takes out the paper disc on the disc loading device, and then the unwinding device is used to unwind the paper disc, and then the lifting device mounts the paper disc on the chuck core shaft of the old paper disc, so that the chuck core shaft moves to clamp the paper disc through the chuck, thereby completing the replacement of the paper disc.

[0048] The main controller SIMOTION D455-2 and the expansion controller CU320-2 of the present invention realize the control of the SINAMICS S120 driver through DRIVE-CLIQ, and the SINAMICS S120 driver drives the AC servo motor to quickly and accurately complete the process actions of each device; it can make the servo drive response time less than 50ms, and make the unwinding speed match the operation of the ultra-high-speed (greater than 12,000 cigarettes / minute) cigarette making unit or filter rod forming unit in real time. The entire paper tray replacement machine control system of the present invention can complete the driving of 9 AC servo motors and 1 AC asynchronous motor, the collection of 16 sensor digital quantity signals, and the enabling of 20 solenoid valves. The control system of the present invention is a control system based on SIEMENS SIMOTION platform, which includes a main controller SIMOTION D455-2, an expansion controller CU320-2, a SINAMICS S120 drive and a Festo remote I / O module, and the control bus is PROFINET and DRIVE-CLIQ. The system can minimize the control level, minimize the electrical components and simplify the electrical component brands, and can optimize the system reliability and stability.

[0049] All electrical detection, drive, motor, etc. in the control system of the present invention adopt Siemens brand, and pneumatic components adopt Festo brand, so that the brand types of electrical components are reduced, ensuring the electrical compatibility of the system, thereby better guaranteeing the reliability and stability of the control system.

It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
