In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
The embodiment provides a control method of a wrapper roller, as shown in fig. 1, which is a flowchart of a control method of a wrapper roller provided in an embodiment of the present specification, and is applied to a wrapper, where the wrapper roller includes a wrapper roller and a mandrel, and the method includes the following steps:
step S101: before the head of the strip steel reaches the mandrel, controlling the wrapper roll to move to a first preset position from an initial position;
step S102: when the head of the strip steel reaches a mandrel, controlling the winding assisting roller to wind the strip steel onto the mandrel at a first speed;
step S103: when the coiling state of the strip steel meets a preset state, controlling the wrapper roll to move to the initial position, and adjusting the speed of the wrapper roll to be a second speed, wherein the second speed is less than the first speed;
and S104, when the tail of the strip steel reaches the coiling machine, controlling the wrapper roll to move from the initial position to a second preset position, and controlling the wrapper roll to press the tail of the strip steel at a third speed.
The specific implementation scenario of the control method for the wrapper roller of the coiling machine provided by the embodiment of the specification can be that the computer controls the coiling machine to perform the coiling operation of the strip steel through the PLC. The coiling machine can comprise a mandrel, a pinch roll, a wrapper roll and a conveying roller way, wherein the quantity of each part of the coiling machines with different models can be different. As shown in fig. 2, a schematic mechanism diagram of a coiling machine provided in an embodiment of the present disclosure is shown, in this embodiment, the coiling machine includes 3 auxiliary winding rolls, as shown in fig. 2, 1 is a coiling mandrel, 2 is a strip steel, 31 is a first auxiliary winding roll, 32 is a second auxiliary winding roll, 33 is a third auxiliary winding roll, 41 is an upper pinch roll, 42 is a lower pinch roll, 5 is a hot metal detector, 6 is an unwinding trolley, and 7 is a transportation roller table.
In the specific implementation process, step S101 is first executed: and controlling the wrapper roll to move from the initial position to a first preset position before the head of the strip steel reaches the mandrel.
Specifically, a certain time is needed for the strip steel to reach the mandrel from the conveying roller way, and the wrapper roll can be controlled to move from the initial position to the first preset position before the strip steel reaches the mandrel. The initial position may be a position where the wrapper roller is opened at a maximum distance from the mandrel, and the first preset position may be a position where the wrapper roller is close to the mandrel for a rolling operation. For example, while the strip 2 is still on the transport table 7, the wrapper rollers 31, 32, 33 are moved from the initial position furthest from the mandrel to a first predetermined position to wait for the strip to reach the mandrel.
Then, step S102 is executed: and when the head of the strip steel reaches the mandrel, controlling the wrapper roll to wind the strip steel on the mandrel at a first speed.
In the specific operation, before the head of the strip steel reaches the mandrel, the wrapper roll is controlled to idle at a first preset position at a first speed. When the head of the strip steel reaches the mandrel, the mandrel winds the strip steel, and meanwhile, the wrapper rolls run at the first speed to assist the mandrel in winding the strip steel.
As an alternative embodiment, before the controlling the wrapper roll to wind the strip steel on the mandrel at the first speed, the method further comprises:
and acquiring an initial speed of the mandrel, and taking the initial speed as the first speed.
In the specific implementation process, the speed of the mandrel for coiling the strip steel can be the first speed of the wrapper roll, so that the influence of the wrapper roll on the quality of the strip steel caused by the mismatching of the speed of the wrapper roll and the speed of the mandrel can be reduced. For example, before the strip 2 reaches the mandrel 1, the wrapper rollers 31, 32, 33 move to a first preset position and the mandrel 1 idles at a first speed. When the strip steel 2 reaches the mandrel 1, the strip steel 2 is coated on the mandrel 1 through 3 wrapper rolls, so that the mandrel 1 can wind the strip steel 2 more quickly.
Then, step S103 is executed: and when the coiling state of the strip steel meets a preset state, controlling the wrapper roll to move to the initial position, and adjusting the speed of the wrapper roll to be a second speed, wherein the second speed is less than the first speed.
Specifically, after the strip is wound on the mandrel to a certain extent on the coiler, the wrapper roll is not needed to press the strip again. At this time, the wrapper roller is controlled to move from the current position to the initial position and then the running speed of the wrapper roller is reduced to the second speed. The preset state can be the number of turns of the strip steel coiled on the mandrel, the time for coiling the strip steel by the mandrel and the like, and the second speed is lower than the first speed and can be 2m/s, 4m/s, 5m/s and the like.
As an alternative embodiment, step S103 further includes: and when the reeling duration is longer than a first preset duration, controlling the wrapper roll to move to the initial position.
Specifically, a load relay is arranged on the coiler mandrel, when the head of the strip steel reaches the coiler mandrel, the load relay can generate a delay signal, and the delay signal is a first preset time length. The coiling state of the strip steel refers to the time length of the strip steel coiled by the mandrel, and when the time length of the strip steel coiled meets the preset time length (the first preset time length can be 1-5 s), namely after the time delay signal is sent out, the wrapper roller is controlled to move from the current position to the initial position.
As an alternative embodiment, step S103 further includes: after the wrapper roller moves to the initial position, keeping the first speed of the wrapper roller to a second preset time length after the wrapper roller moves to the initial position;
and adjusting the speed of the wrapper roll from the first speed to the second speed according to a preset adjusting speed.
In the specific operation, in consideration of protecting the equipment, after the wrapper roll is moved to the initial position, the speed of the wrapper roll is still kept unchanged, and after the speed is maintained for a second preset time period, the speed of the wrapper roll is reduced to a second speed according to the adjusting speed. The second preset time period can still be realized by the signal generated by the load relay on the mandrel and delaying to the second preset time period. In so doing, the wear of the wrapper roll on the surface of the strip steel caused by the direct deceleration is also avoided.
For example, when the head of the strip steel 2 enters the coiling machine, the mandrel 1 of the coiling machine generates a load relay signal and delays for 1-2s, and after the strip steel is coiled for 1-2s, the first wrapper roller 31, the second wrapper roller 32 and the third wrapper roller 33 are all opened to the initial position farthest from the mandrel 1, so that enough space is reserved for the coiling of the strip steel 2. Meanwhile, after the mandrel 1 generates a load relay signal again and delays for 1-2s, the first wrapper roller 31, the second wrapper roller 32 and the third wrapper roller 33 all decrease from the first speed to the second speed, so that the wrapper rollers are prevented from idling at a high speed and electric energy is saved. The reason for reducing the speed of the wrapper roller after delaying for 1-2s is as follows: the speed of the band steel and the speed of the wrapper roll are asynchronous due to the instant deceleration of the opening of the wrapper roll, so that the band steel and the wrapper roll are prevented from generating friction slip; and the delayed deceleration also plays a role of protecting equipment. In the embodiment, the second speed is preferably 1-2m/s, so that the requirement of low-speed idle running of the wrapper roller is met, and the wrapper roller is convenient to control to run at the increased speed again.
Step S104 is performed next: and when the tail part of the strip steel reaches the coiling machine, controlling the wrapper roll to move from the initial position to a second preset position, and controlling the wrapper roll to press the tail of the strip steel at a third speed.
Specifically, a hot metal detector is arranged in front of a pinch roll (shown in figure 2) of the coiling machine, and when the tail of the strip steel leaves a conveying roller way, namely the strip steel cannot be detected by the hot metal detector, the wrapper roll is controlled to move from an initial position to a second preset position to press the tail of the strip steel. The second preset position is the position where the wrapper roll is tightly attached to the strip steel when the coiling of the strip steel by the mandrel is finished.
As an alternative embodiment, step S104 further includes: and acquiring the running speed of the mandrel when the tail of the strip steel reaches the coiling machine, and taking the running speed as the third speed.
The running speed of the mandrel is generally low when the strip is being wound to the end stage. And when the tail part of the strip steel reaches the coiling machine, the speed of the wrapper roll is adjusted to the speed of the mandrel so as to press the tail part of the strip steel, and the speed is the third speed. When the wrapper rollers press the tail of the strip steel, one wrapper roller can be selected to press the tail independently or a plurality of wrapper rollers can be selected to press the tail simultaneously, and the method is not limited herein.
For example, in the whole coiling process, the PLC control system tracks the position of the strip steel in real time, when the tail of the strip steel 2 reaches the front pinch rolls 41 and 42 of the coiling machine, namely the tail of the strip steel 2 cannot be detected by the hot metal detector 5, the PLC controller controls the speed of the wrapper roll to run at a third speed and close the tail pressing the strip steel 2 to prevent the strip steel from being unwound, the third speed is the same as the running speed of the mandrel 1 (preferably 0.5-1.5 m/s), and when the speeds of the mandrel 1 and the wrapper roll are not synchronous, friction is generated between the strip steel 2 and the wrapper roll to scratch the surface of the strip steel 2 to influence the surface quality of the strip steel. The tail pressing auxiliary roller can select the first auxiliary roller 31 to press the tail, or select the third auxiliary roller 33 to press the tail, or select the first auxiliary roller 31 and the third auxiliary roller 33 to press the tail simultaneously, and the like.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
the winding aid roller of the winding machine is reasonably controlled in speed in the production process, so that the electric energy consumption of the winding aid roller is reduced, the energy is saved, and the damage of the winding aid roller device is avoided; moreover, the effect can be achieved by optimizing the primary PLC system, additional equipment is not needed, and implementation is facilitated.
