In order to reduce the flat rolling degree of a steel coil, the method adopted at present generally reduces the collapse degree of the steel coil by reducing the weight of the steel coil in the process of rolling strip steel into the steel coil, and carries out flat rolling prevention treatment. And then transferring the steel coil to a transportation mechanism, and transporting the steel coil to a specified position through the transportation mechanism. However, when the steel coil is subjected to the flat coil prevention treatment at present, only one station is reserved for temporarily placing the steel coil, so that the steel coil needs to be transferred to the conveying mechanism, the coiling machine located at the upstream continues to coil the next piece of strip steel, and the flat coil prevention treatment is continuously performed on the coiled and formed steel coil. Therefore, the coiling speed of the coiling machine is slowed down, the conveying efficiency of the steel coil is reduced, and the production rhythm is slowed down.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
After the strip steel is coiled, uneven phase change and uneven volume expansion can occur along the thickness direction and the width direction, so that the interlayer friction force of the steel coil is reduced. Therefore, the steel coil is easy to collapse gradually under the action of self gravity after being detached. The steel coil is changed from the original circular shape after being disassembled into the oval shape, and the steel coil can be called as a flat coil of the steel coil. In addition, when a high coiling temperature or thin specification steel coil is produced, the steel coil cannot support the dead weight due to self rigidity, and flat coiling is easy to occur.
At present, the modes for preventing the steel coil from being flatly coiled are mainly as follows: reducing the weight of the steel coil to reduce the collapse degree of the steel coil; (2) improving the coiling tension to increase the interlayer friction force; (3) after the coiling is finished, staying at the mandrel to delay coil unloading; (4) hanging and stopping by utilizing a traveling crane C-shaped hook; and (5) changing the coiling temperature to complete the phase change in advance. However, the above method is not beneficial to equipment maintenance, or greatly reduces the production rhythm, or greatly changes the physical property of the steel coil.
The applicant notices that the existing modes for preventing the steel coil from being flatly coiled are not beneficial to batch production and have the problem of low steel coil transportation efficiency. Based on the above-mentioned discovered problems, the applicant improves the way of preventing the steel coil from being flatly wound, and the following further describes the embodiments of the present application.
As shown in fig. 1, the present application provides a method for transporting a steel coil, comprising the following steps:
the steel coil 4 is sequentially transferred to the temporary storage mechanism 1 and the transfer mechanism 2 to be transversely placed in a first state, the total placing time is T1, and the transverse placing is a placing state that the peripheral surface of the steel coil 4 is a contact surface; the steel coil 4 is transferred to the conveying mechanism 3 and is transversely placed in a second state, and the placing time is T2; wherein the included angle between the gravity line of the steel coil 4 in the first state and the gravity line in the second state is 85-95 degrees, and T1 is equal to or close to T2.
Before the steel coil is subjected to the anti-flat coil treatment, a coiler is generally used to coil the strip steel into the steel coil. The coiler is not only the last key process of the hot rolling production line, but also important equipment for coiling the hot rolling strip steel into a steel coil. The current coiling machine mainly comprises a pinch roll, a mandrel, a wrapper roll, a coil stripping mechanism 7 and other equipment. The strip steel coiling process mainly comprises the steps that strip steel enters a roll gap of a pinch roll, the head of the strip steel is bent through the pinch roll, the head of the strip steel enters the roll gap of a wrapper roll, and the head of the strip steel is wound on a mandrel under the pressure of the wrapper roll. By applying tension to the strip steel, the strip steel is continuously wound on the mandrel, and finally a steel coil 4 is formed.
After the steel coil 4 is formed, the steel coil 4 can be unloaded from the mandrel by using the coil unloading mechanism 7, and is transferred to the temporary storage mechanism 1 to be placed on the temporary storage mechanism 1 for a period of time. It should be noted that the steel coil 4 is transversely placed on the temporary storage mechanism 1 in the first state. The transverse placement state here is understood to mean that the plane of the outer circumferential surface of the steel coil 4 and the plane of the temporary storage mechanism 1 are perpendicular to each other. After the steel coil 4 is placed on the temporary storage mechanism 1 for a certain period of time, the steel coil 4 placed in the first state is then transferred onto the transfer mechanism 2 in the same state, and the steel coil 4 is also placed on the transfer mechanism 2 for a certain period of time. The steel coil 4 is placed on the temporary storage mechanism 1 and the transfer mechanism 2 in the first state for a time period T1.
Subsequently, the steel coil 4 is rotated to change from the first state to the second state. The second state is understood here to mean that the coil 4 is rotated in situ about the central axis of the coil 4. After the rotation is finished, the included angle between the gravity line in the second state and the gravity line in the first state is 85-95 degrees. After the steel coil 4 is switched to the second state, the steel coil 4 in that state may be transferred to the transport mechanism 3. In this way, the steel coil 4 in the second state can be driven by the transportation mechanism 3 for the running time T2, and finally reaches the designated position. And after the coil 4 reaches the designated position, the shape of the entire coil 4 is also the shape that was originally detached from the mandrel. Through the mode of the above-mentioned rotatory coil of strip 4, when having avoided coil of strip 4 to reach the assigned position, take place deformation under the effect of self gravity to reach the problem that influences the subsequent handling and develop because of deformation.
The following explains a principle of preventing the steel coil 4 from being deformed, that is, preventing the steel coil from being wound in a flat shape, by making the steel coil 4 in a circular shape when detached from the mandrel.
As shown in fig. 2, when the steel coil 4 is in the first state, the initial shape is a circle, and the gravity line in this state is the first gravity line 5. Then the steel coil 4 gradually becomes flat under the action of self gravity, namely, the steel coil gradually changes from a circle to an ellipse. When the steel coil 4 rotates and is switched from the first state to the second state, the gravity line of the steel coil 4 changes. In order to distinguish the gravity lines in the first state from the second state, the gravity line in the second state is named as a second gravity line 6 (shown in fig. 2). Because the angle formed between the second gravity line 6 of the steel coil 4 in the second state and the first gravity line 5 in the first state is close to a right angle, and the time for placing the steel coil 4 in the two states is close. Therefore, the steel coil 4 in the second state is gradually changed from the original oval shape to the original circular shape under the action of its own gravity. And after the steel coil 4 is transported to a designated position by the transport mechanism 3, the original circular shape is substantially restored.
Because the transfer mechanism 2 of this application can also place coil of strip 4 temporarily, and coil of strip 4 can't be placed to current transfer mechanism 2. Consequently, transfer mechanism 2 of this application provides a station in a great deal, can directly place coil of strip 4 on temporary storage mechanism 1, need not to wait to transfer mechanism 2 and shift coil of strip 4 to transport mechanism 3 after, just lift coil of strip 4 off from the dabber. Thus, the conveying efficiency of the steel coil 4 is accelerated.
Of course, in one embodiment, the steel coil 4 can rotate on the transferring mechanism 2 to switch from the first state to the second state. In another embodiment, a separate rotating mechanism may be provided between the transfer mechanism 2 and the transport mechanism 3 to rotate the steel coil 4. Besides, a rotating mechanism can be arranged on the conveying mechanism 3, so that the steel coil 4 rotates only when being transferred to the conveying mechanism 3, and the states are switched. The rotation time of the steel coil 4 is not specifically limited, and can be determined according to actual conditions.
In one embodiment, the steel coil 4 is placed on the temporary storage mechanism 1 in the first state for a time period T3, the steel coil 4 is placed on the transfer mechanism 2 in the first state for a time period T4, the time periods T3 and T4 are equal or similar, and the sum of T3 and T4 is equal to T1.
According to the whole scheme, the steel coil 4 needs to be placed on the temporary storage mechanism 1 for a period of time, then placed on the transfer mechanism 2 for a period of time, and then the steel coil 4 is rotated, transferred and the like. If the beat between transport mechanism 2 and the temporary storage mechanism 1 is not in time, then will appear coil of strip 4 and can not in time transport, namely the coil of strip 4 that the later waited for to transport, need wait for extra time, wait to transport mechanism 2 from the position that is close to transport mechanism 3, come to the position that is close to temporary storage mechanism 1, just can carry out the transportation to coil of strip 4.
The following description is made by taking some examples, and if the operation speed of the transfer mechanism 2 is too slow, it is easy to cause that the previous steel coil 4 is still just placed on the transfer mechanism 2, and the next steel coil 4 is also placed on the temporary storage mechanism 1, so that the steel coil 4 placed on the temporary storage mechanism 1 needs to wait for the steel coil 4 on the transfer mechanism 2 to be transferred to the transport mechanism 3, and then the steel coil can be transferred to the transfer mechanism 2 for placement. That is, the latter coil 4 needs to wait for a certain time. Thus, the transportation time of the steel coil 4 is prolonged, and the transportation efficiency of the steel coil 4 is reduced.
It is easy to understand that if the running speed of the transfer mechanism 2 is too fast, the phenomenon that the previous coil 4 waits for the next coil 4 easily occurs. The transportation time of the steel coil 4 is prolonged, and the transportation efficiency of the steel coil 4 is reduced.
In order to adjust the running speed of the transfer mechanism 2, the working beat between the transfer mechanism 2 and the temporary storage mechanism 1 is more timely. The steel coil 4 can be placed on the temporary storage mechanism 1 and the transfer mechanism 2 in close time. Like this, just need not consider long this factor of placing of coil of strip 4 in two mechanisms, only adjust the speed that transport mechanism 2 transferred coil of strip 4 to transport mechanism 3, and transport mechanism 2 shifts coil of strip 4 from temporary storage mechanism 1 to the speed on transport mechanism 2. When leaving the station that can place coil of strip 4 on transport mechanism 2, it is long when placing coil of strip 4 on temporary storage mechanism 1 just accomplishes predetermined placing. The station that can supply coil of strip 4 to place on temporary storage mechanism 1 and the transport mechanism 2 is in the user state always for the idle phenomenon of station can not appear, has reduced the degree of difficulty of adjusting transport mechanism 2 functioning speed.
Of course, in other embodiments, the length of time that the steel coil 4 is placed on the temporary storage mechanism 1 may be different from the length of time that the steel coil 4 is placed on the transfer mechanism 2. As long as it can be ensured that the escrow mechanism 1 and the transfer mechanism 2 can be properly matched. For example, the time period T3 for placing the steel coil 4 on the temporary storage mechanism 1 may be longer than the time period T4 for placing the steel coil 4 on the transfer mechanism 2. Or the placing time period T3 of the steel coil 4 on the temporary storage mechanism 1 may be shorter than the placing time period T4 of the steel coil 4 on the transfer mechanism 2. However, the total placing time of the steel coil 4 on the two mechanisms needs to be equal to T1
In one embodiment, the coil 4 is rotated to switch the coil 4 from the first state to the second state before transferring the coil 4 to the transport mechanism 3. Because the steel coil 4 is always in the second state on the transportation mechanism 3, the calculation difficulty of the placing time of the steel coil 4 in the first state and the second state respectively is reduced.
The above-mentioned rotating mechanism which can rotate the steel coil 4 can be arranged on the transferring mechanism 2, and can also be arranged beside the conveying mechanism 3. When the rotating mechanism is arranged on the transferring mechanism 2, the space occupied by the rotating mechanism is reduced, the whole placing time of the steel coil 4 on the transporting mechanism 3 is saved and is T2, the steel coil is always placed in the second state, and the transporting mechanism 3 which is adopted at present generally adopts a track or a chain and the like. And a rotating mechanism is not arranged on the conveying mechanism 3, so that a user does not need to adjust the placing time T2 when the steel coil 4 is in the second state, and only needs to adjust the time spent by the two processes of the front temporary storage mechanism 1 and the transfer mechanism 2, thereby reducing the design difficulty of the whole scheme.
Of course, a rotating mechanism for rotating the steel coil 4 can be further arranged on the transportation mechanism 3, and the transportation mechanism 3 adopted at present is generally a track or a chain, so that a plurality of rotating mechanisms are required to be arranged at intervals in the transportation direction of the transportation mechanism 3, so that the steel coil 4 can randomly rotate on one of the rotating mechanisms on the transportation mechanism 3, and the plurality of rotating mechanisms are arranged on the transportation mechanism 3, and the purpose of transporting a plurality of steel coils 4 at a time can be achieved.
In one embodiment, the steel coil 4 is rotated by the transfer mechanism 2 to switch the steel coil 4 from the first state to the second state. Utilize transport mechanism 2 to rotate coil of strip 4, set up a rotary part on transport mechanism 2 promptly, utilize this part to make coil of strip 4 take place to rotate. Thus, the rotating part and the transfer mechanism 2 are integrated on one part, and the occupied space of the whole set of equipment is saved. In addition, the function of the transfer mechanism 2 is increased, and the application range of the transfer mechanism 2 is enlarged.
In one embodiment, the steel coil 4 is rotated after being placed on the transfer mechanism 2 through the transfer mechanism 2, and the first state is switched to the second state.
The transfer mechanism 2 can be used for placing the steel coil 4, and can act on the steel coil 4 when the steel coil 4 needs to rotate, so that the steel coil 4 rotates, and is switched into the second state from the first state. Further richened transport mechanism 2's function like this for this transport mechanism 2 has multiple functions, has enlarged transport mechanism 2's application range.
As shown in fig. 3 to 6, the present application further provides a steel coil transportation device, which includes a temporary storage mechanism 1, a transfer mechanism 2 and a transportation mechanism 3. The temporary storage mechanism 1 is positioned beside the coil unloading mechanism 7 and is used for placing the steel coil 4; the transfer mechanism 2 is positioned on one side of the temporary storage mechanism 1 away from the coil unloading mechanism 7, and is used for placing the steel coil 4 and rotating the steel coil 4; the transportation mechanism 3 is located beside the transfer mechanism 2 and is used for conveying the steel coil 4.
The above-described steel coil 4 transport mechanism 3 will be described with reference to a specific example.
After the strip steel is completely coiled, the coil of strip 4 can be disassembled from the mandrel by utilizing a coil unloading mechanism 7 (such as a coil unloading trolley) and transferred to the temporary storage mechanism 1. At this moment, the steel coil 4 is placed on the temporary storage mechanism 1 for a period of time, and then the steel coil 4 placed on the temporary storage mechanism 1 is transferred to the transfer mechanism 2 by the transfer mechanism 2. After the steel coil 4 comes to the transfer mechanism 2, the steel coil 4 is placed on the transfer mechanism 2 for a period of time. And then, rotating the steel coil 4, and finally transferring the rotated steel coil 4 to the conveying mechanism 3 by using the transfer mechanism 2. Wherein, the steel coil 4 keeps the rotated state on the transportation mechanism 3 until the steel coil 4 is transported to the designated position.
For convenience of understanding, in this example, the state before the steel coil 4 is rotated is named as a first state, and the state after the steel coil 4 is rotated is named as a second state. When the steel coil 4 is in the first state, the plane of the outer circumferential surface of the steel coil 4 is perpendicular to the horizontal plane of the steel coil 4. And when the steel coil 4 is in the second state, the included angle between the gravity line of the steel coil 4 and the gravity line in the first state is close to a right angle.
Since the steel coil 4 is always placed in the first state on the temporary storage mechanism 1 and the transfer mechanism 2, and is always placed in the second state on the transport mechanism 3. And the placing time of the steel coil 4 in the first state is similar to the placing time of the steel coil 4 in the second state. Therefore, the steel coil 4 gradually collapses, i.e. becomes flat, into an oval shape from the original round shape under the action of its own weight. The ellipse then rotates and gradually changes from elliptical to circular under the action of its own weight. As for the shape changing process of the steel coil 4, it can be understood that the steel coil 4 is changed from the circular shape to the elliptical shape in the first state, and then is changed from the elliptical shape to the circular shape in the second state.

After the steel coil 4 is placed on the placing component 22, the steel coil is driven by the placing component 22 to rotate, and the steel coil is converted from the first state to the second state. Since the placement module 22 is mounted on the body 21 of the transfer mechanism 2, one placement module 22 is actually provided on the body 21 that can perform the transfer function. I.e. integrating both functions together. The space occupied by the entire transfer mechanism 2 is reduced.

In addition, a plurality of rotating mechanisms arranged at intervals can be arranged on the transport mechanism 3. I.e. the coil 4 is rotated after the coil 4 has been transferred to the transport mechanism 3. The specific arrangement is not listed here.
With continued reference to fig. 5, in one example, the placement assembly 22 can be two rollers spaced apart. The steel coil 4 is placed on the two rollers, and when the rollers rotate, the steel coil 4 can be driven to rotate together.
In order to prevent the bearing of the high-temperature steel coil baking roller, the bearing seat of the roller can be designed into a water-cooling bearing seat with automatic dry oil lubrication.
Of course, a separate placement module 22 may be provided beside the body 21. When the steel coil 4 needs to be placed, the steel coil 4 is transferred to the placing assembly 22 to be placed, and then the next process is continued.
In one embodiment, transfer mechanism 2 further comprises a drive assembly (not shown) mounted on the rotating end face of placement assembly 22. The driving assembly is arranged on the rotating end face of the placing assembly 22, so that the space occupied by the driving assembly is reduced, and the probability of interference between the steel coil 4 and the driving assembly during rotation is reduced.
It should be noted that the present embodiment uses a hydraulic motor as a driving component, but the driving component may also be a servo motor, a stepping motor, etc., and is not limited in particular herein. In addition, the driving assembly can be arranged, and meanwhile, parts such as a speed reducer and the like capable of adjusting the running speed of the driving assembly can be arranged.
