Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a trimming machine based on a WinCC host computer control system. Background Technology

[0002] In existing technology, when a product needs edge trimming, manual verification is required to ensure the equipment is functioning correctly, the parameters are accurate, and the disc shear opening is normal before the material can be rolled up for trimming. The material is loaded onto the uncoiler by a feeding trolley, and manually trimmed by the disc shear before being fed to the coiler. After the coiler winds the material, the uncoiler is tensioned and its speed is increased to the set speed and maintained. At the same time, the trimmed waste edge is rolled up using the waste edge coiler. During trimming, the diameter of the waste edge coil must be manually observed. If the diameter is too large, the coil must be unwound in time. When the diameter of the uncoiler reaches its minimum, the machine is stopped and the speed is reduced to release the tension. The entire trimming process takes about half an hour, and there must be no abnormal shutdowns during the process, otherwise the product will be scrapped.

[0003] Currently, manual inspection of the equipment is required before startup, including: the hydraulic pump station's level and pressure; the temperature of the uncoiling motor, winding motor, and transmission control system; whether the opening of the disc edge trimmer matches the cutting width; manual observation is required during machine operation; the motor current needs to be observed during machine operation; if the waste edge roll diameter is too large, it should be unloaded in time; the uncoiling machine should be stopped in time when it reaches the minimum roll diameter, otherwise runaway will occur; there are many conditions that require manual confirmation, resulting in a decrease in production efficiency.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] This utility model discloses an edge trimming machine based on a WinCC host computer control system, such as Figure 1 As shown, the system includes an uncoiler 1, a disc shear 2, a coiler 3, a hydraulic pump station 4, a waste edge coiler 5, a first valve platform 6, a second valve platform 7, a main control panel 8, and a PLC controller 16. The output end of the uncoiler 1 is connected to the input end of the disc shear 2, and the output end of the disc shear 2 is connected to the input end of the coiler 3. The waste edge outlet of the disc shear 2 is connected to the waste edge coiler. The uncoiler 1 is fed by a feeding trolley 13, and the coiler 3 is unloaded by a discharging trolley 14.

[0021] Uncoiling machine 1 is equipped with an uncoiling drive control cabinet 9 and an uncoiling drive motor, and winding machine 3 is equipped with a winding drive control cabinet 10 and a winding drive motor, such as Figure 2 As shown, the PLC controller 16 is connected to the unwinding drive control cabinet 9, the winding drive control cabinet 10, the solenoid valves of the first valve seat 6 and the second valve seat 7, the main control panel 8, and the hydraulic pump station 4 via the DP bus. The unwinding drive control cabinet 9 controls the operation of the unwinding drive motor, and the winding drive control cabinet 10 controls the operation of the winding drive motor. The PLC controller 16 is connected to the WinCC host computer 12 via the switch 17, and the WinCC host computer 12 is connected to the loudspeaker.

[0022] Both the unwinding drive motor and the winding drive motor are equipped with thyristor converters. The unwinding drive control cabinet 9 and the winding drive control cabinet 10 are connected to the thyristor converters via a DP bus.

[0023] The unwinding drive motor and the winding drive motor are equipped with temperature sensors. The unwinding drive control cabinet 9 and the winding drive control cabinet 10 are connected to the temperature sensors via a DP bus. The unwinding drive motor and the winding drive motor are equipped with current sensors. The unwinding drive control cabinet 9 and the winding drive control cabinet 10 are connected to the current sensors via a DP bus.

[0024] The unwinder 1 and winding machine 3 of this utility model use ABB DCS800 series fully digital thyristor converters as speed controllers to control the unwinding drive motor, winding drive motor, and two DC drive motors. The DC drive device is connected to the PLC controller 16 Siemens 315-2PN / DP via DP bus.

[0025] The first valve station 6, the second valve station 7, and the main control station 8 use Siemens ET200S and ET200M as substations. The substations are connected to the main station PLC controller 16 via DP bus. Operators can issue commands to the PLC controller 16 through buttons and switches on the main control station 8 panel or by operating a computer to complete the operation of the entire machine train.

[0026] The hydraulic pump station 4 of this utility model consists of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, an overflow valve, an energy storage tank, and a cooling system. The hydraulic pump station 4 provides stable pressure and flow to the oil cylinder and the oil motor. The hydraulic pump station 4 is connected to the first valve seat 6 and the second valve seat 7 on site through pipelines to provide kinetic energy to the oil cylinder and the oil motor.

[0027] After the hydraulic oil is regulated in direction, pressure and flow through the valve platform, the external pipeline transmits the hydraulic oil to the oil cylinder or oil motor. The electromagnetic directional valves on the first valve platform 6 and the second valve platform 7 control the change of direction, the magnitude of force and the speed, so as to drive various hydraulic machines to do work.

[0028] The second valve station 7 has the following functions:

[0029] 1. Control the lifting and lowering of the hydraulic cylinder and the forward and backward movement of the hydraulic motor of the feeding trolley 13 to transport the material onto the mechanical roll of the uncoiler 1;

[0030] 2. The material is tightened by driving a mechanical reel with a hydraulic cylinder;

[0031] 3. The inlet guide plate is lifted and driven by the hydraulic cylinder to send the material head to the hydraulic cutting head shear in front of the disc shear 2;

[0032] 4. The hydraulic cutter head driven by the oil cylinder cuts off the irregular material head and then sends it into the disc shear machine 2.

[0033] The first valve platform 6 has the following functions:

[0034] 1. When the material head arrives at the edge trimming unit, use the oil motor to drive the screw to adjust the disc shearing opening (the width to be cut).

[0035] 2. The material head is sent to the winding machine 3 by controlling the lifting and driving of the outlet guide plate through the hydraulic cylinder;

[0036] 3. The sleeve is tightened by driving a mechanical reel with a hydraulic cylinder;

[0037] 4. The hydraulic cylinder controls the forward and backward movement of the winding aid to wrap the material head onto the mechanical reel;

[0038] 5. After the material is sheared, control the hydraulic cylinder of the unloading trolley 14 to lift and lower, and the hydraulic motor to move forward and backward, so as to transport the material to the storage platform.

[0039] The PLC controller 16 is equipped with an Ethernet interface and is connected to the engineer station 11 and the WinCC host computer 12 through the switch 17. The tension calculation of the uncoiler 1, the solenoid valve control of the first valve seat 6 and the second valve seat 7, and the start and stop of the hydraulic pump station 4 are all completed by the PLC controller 16.

[0040] During normal operation, the PLC controller 16 is connected to the thyristor converter of the winding drive motor via the DP bus. The current of the winding drive motor is read by the current sensor. The logic of the PLC controller 16 determines whether the alarm value has been reached. If the alarm value is reached, the variable is sent to the WinCC host computer 12 in binary form via Profinet Ethernet communication.

[0041] When the current of the winding drive motor is too high, the operator needs to take measures such as "stopping the machine, reducing speed, and observing the motor temperature". These measures should be converted into a sound file and stored in the WinCC host computer. When an alarm occurs, the alarm variable will trigger the sound file, and the measures to be taken will be played out through the loudspeaker to remind the operator.

[0042] like Figure 2 As shown, when the winding drive motor current is too high, the following analysis steps are adopted;

[0043] Step 1) Configure the PLC controller 16 hardware and the thyristor converter device controlling the winding drive motor for communication connection. Configure the PLC controller 16 with the corresponding GSD file, select Profibus-DP communication, and fill in the hardware address, configuration parameters and baud rate.

[0044] Step 2) Set the corresponding address, baud rate and communication protocol for the AS800 frequency converter. After ensuring normal communication, the PLC controller 16 reads the temperature, current and transmission speed parameters of the winding machine 3.

[0045] Step 3) PLC controller 16 calls the standard function block, reads the winding drive motor current and compares it with the motor's rated current, and determines whether the alarm value has been reached. If the alarm value is reached, prompts to continue operation after 20 seconds.

[0046] Step 4) The operator analyzes the reasons for the excessive current of the winding drive motor, such as the excessive load on the winding machine 3, the excessive speed of the machine train, the excessive unwinding tension, the incorrect gearbox gear, or the motor temperature not being within the specified requirements.

[0047] Step 5) The operator inputs a custom voice (in step 4, Zhenhong analyzes the cause of excessive motor current) into the PLC controller 16 through the main control panel 8. For example, "reduce tension and reduce speed". The PLC controller 16 transmits the voice data to the WinCC host computer 12 via Profinet Ethernet communication.

[0048] Step 6) WinCC host computer 12 converts MP3 audio to WAV format and saves the WAV audio file;

[0049] Step 7) WinCC host computer 12 creates signal variables in the form of binary data management variables. WAV format sound files can be accessed through the server computer. When using an absolute path, the sound file can be accessed through the server computer and the client computer.

[0050] Step 8) In the WinCC K7.0.3.0 version host computer 12 alarm, configure the signal to be emitted according to the specific message received. The incoming message can activate the signal variable, and the signal variable will trigger the sound file in the specified signal device;

[0051] Step 9) The WinCC host computer 12 emits a specific alarm voice prompt through the external loudspeaker 15. After the operator confirms the message, the signal variable is reset and the voice alarm is terminated.

[0052] During the above process, if multiple messages are triggered, they will not be played simultaneously. To achieve clear sound, one message will be played at a time.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
