Description

Technical Field

[0001] The present invention relates to the field of cold-rolled steel coil bundling, and in particular to an intelligent device and method for bundling steel coils. Background Art

[0002] Cold rolled steel coil bundling is the last very important process in the strip steel production process, which directly affects the quality of the steel coil products delivered to customers. Before bundling, the steel coil needs to be packed inside and outside to prevent the surface of the steel coil from being exposed to the air for a long time to cause rust or bumps on the surface of the steel coil, thereby affecting its surface quality. The purpose of bundling steel coils is to fix the outermost iron sheet and inner and outer steel corners of the steel coil, so that the surface of the steel coil is fully isolated from the outside world to ensure the surface quality of the steel coil. The bundling of steel coils mainly includes circumferential bundling and radial bundling of steel coils. The circumferential bundling of steel coils refers to the circumferential bundling of the steel coils by the circumferential bundling belt in the closed circumferential guide formed by a specific mechanism, and then the circumferential bundling machine performs circumferential bundling. The radial bundling refers to the circumferential bundling belt in the closed radial guide formed by the specific mechanism passing through the hollow interior of the steel coil cylinder. The radial bundling machine performs radial bundling. For the steel coils that have been completed with inner and outer packaging, different bundling methods have different bundling effects on the steel coils, and the efficiency of steel coil bundling is also quite different.

[0003] Most of the existing cold-rolled steel coil bundling methods use automatic bundling machines to bundling the steel coils circumferentially and radially, or use manual methods to bundling the steel coils circumferentially and radially. Bundling the steel coils using automatic circumferential bundling machines and automatic radial bundling machines requires transporting the steel coils to two different special bundling equipment for bundling, which affects the efficiency of bundling the steel coils. The space occupied by the equipment is large, which increases the complexity of the steel coil bundling process. Manual bundling has the problems of large bundling repetition intensity and low bundling efficiency.

[0004] Therefore, it is particularly important to design a device that can perform radial and circumferential bundling at the same time, with a simple and reliable structure, in order to improve the efficiency of on-site cold-rolled steel coil bundling. Summary of the invention

The linear screw mechanism 8 is controlled to make the circumferential baler 23 descend to the baling position and perform circumferential baling. After the circumferential baling is completed, the arc-shaped guide belt arm 3 is pulled back to a specific position under the traction of the circumferential traction rope 15. The arc-shaped guide belt arm 3 rotates around the rotating shaft 34 to a specific position under the traction of the rotating traction rope 6.

At this time, the second electromagnet 54 is energized to ensure that the arc-shaped guide arms 3 on both sides are tightly fitted. Several circumferential small rollers 29 are provided on the guide arm base 4 and are fully lubricated to reduce the friction force when the arc-shaped guide arm 3 moves on the guide arm base 4. The circumferential strapping 55 enters the circumferential baler 23 and circles the closed guide passage formed under the drive of the corresponding mechanism. The circumferential baler 23 is lowered to the baling position and circumferential strapping is performed by controlling the linear screw mechanism 8. The upper radial laser rangefinder 59 corrects the vertical position parameters of the circumferential baler 23 through real-time measurement. After the circumferential strapping of the first position is completed, the arc-shaped guide arm 3 is pulled back to a specific position under the traction of the circumferential traction rope 15 by controlling the No. 3 motor group 38. The No. 5 motor group 41 drives the circumferential strapping mechanism to move horizontally to the second circumferential strapping position and performs strapping until the circumferential strapping of all positions of the steel coil is completed.

[0052] After completing the circumferential bundling, the fourth motor group 40 and the fifth motor group 41 drive the circumferential bundling mechanism to move to the initial position, and control the second motor group 12 to make the arc-shaped belt guide arm 3 and the arc-shaped belt guide groove 28 rotate around the rotating axis 34 to a specific position under the traction of the rotating traction rope 6, so that the circumferential bundling mechanism moves out of the space occupied by the radial bundling mechanism during bundling.

[0053] The radial baling mechanism moves to the first radial baling position under the drive of the No. 6 motor group 42, and controls the No. 7 motor 47 to make the radial baling shaft 43 move linearly to the specified position under the traction of the radial shaft forward guide rope 51 and form a closed radial strapping guide path with the radial baling guide arm 16. The radial strapping 56 enters the radial baler 49 and circles the closed guide path under the drive of the corresponding mechanism. After the No. 1 motor group 2 drives the radial baling mechanism to move to the specified position, the radial baler 49 performs radial baling.

After the radial baling of the steel coil is completed, the eighth motor 48 is controlled to make the radial baling shaft 43 retreat to a specific position under the traction of the radial shaft retreat guide rope 50, and the sixth motor group 42 is controlled to make the radial baling mechanism rotate to the initial position, thereby completing the circumferential and radial baling of the steel coil of this specification.

[0054] The arc-shaped belt guide groove and other sub-mechanisms in the circumferential bundling mechanism designed in the embodiment of the present invention rotate to the specified position after completing the circumferential bundling. The radial bundling mechanism will not interfere with the circumferential bundling mechanism in space during bundling, so that the steel coils can complete circumferential bundling and radial bundling on the bundling device at the same time, thereby improving the efficiency of steel coil bundling. At the same time, the corresponding laser rangefinder is used to automatically measure the diameter parameters and length parameters of the steel coil, and the control system is used to initialize the spatial position parameters to bundle steel coils of different specifications, thereby implementing the intelligent bundling process. The structure is simple, compact and reliable, and the space occupied by the equipment during bundling is fully saved.

[0055] Based on the above-mentioned steel coil bundling intelligent device, steel coils of various sizes can be bundled. In a specific embodiment for bundling steel coils with a size of 1100mm×1300mm (length×diameter), the bundling method includes the following steps:

[0056] Step 1: When bundling steel coils with a size of 1100mm×1300mm (length×diameter), the control system of the intelligent bundling equipment measures parameters such as the diameter and length of the steel coils through the corresponding laser rangefinder before and after the steel coils enter, updates the initial spatial position parameter values ​​of the control system, and calculates the system working parameters required to be set when bundling strip steel of this specification.

[0057] Step 2: The circumferential bundling mechanism moves to the first circumferential bundling position under the drive of the No. 4 motor group 40 and the No. 5 motor group 41. The arc-shaped belt guide arm 3 is connected to the No. 2 recovery shaft 31 through the circumferential traction rope 15. The No. 3 motor group 38 drives the No. 2 recovery shaft 31 to release the circumferential traction rope 15. The arc-shaped belt guide arms 3 on both sides move to the working position at a uniform speed along the belt guide arm base 4 under the dual action of gravity and the circumferential traction rope 15. The arc-shaped belt guide arms 3 on both sides and the arc-shaped belt guide grooves 28 form a closed circumferential strapping guide passage. At this time, the No. 2 electromagnet 54 is energized to make the arc-shaped belt guide arms 3 on both sides fit tightly.

[0058] Step three: a plurality of circumferential small rollers 29 are provided on the tape guide arm base 4, and the circumferential small rollers 29 and the tape guide arm base 4 are fully lubricated, so that the friction force of the arc-shaped tape guide arm 3 when moving on the tape guide arm base 4 is greatly reduced.

[0059] Step four, the circumferential strap 55 enters the circumferential baler 23 from the circumferential strap guide groove 20 and drives the corresponding mechanism to circle the closed circumferential passage formed, and the linear screw mechanism 8 connected to the No. 4 motor group 40 is controlled to move so that the circumferential baler 23 descends to the baling position and performs circumferential strapping. The upper radial laser rangefinder 59 corrects the vertical position parameters of the circumferential baler 23 through real-time measurement, thereby completing the circumferential strapping at the first position.

[0060] Step five, after completing the circumferential bundling at the first position, the system controls the No. 3 motor group 38 to make the arc-shaped guide arm 3 return to a specific position under the traction of the circumferential traction rope 15, and the No. 5 motor group 41 drives the circumferential bundling mechanism to move horizontally as a whole to the second circumferential bundling position and perform circumferential bundling until the circumferential bundling of all positions of the steel coil is completed.

[0061] Step six, after completing the circumferential bundling, the No. 4 motor group 40 and the No. 5 motor group 41 drive the circumferential bundling mechanism as a whole to retreat to the initial position, and the system controls the No. 2 motor group 12 to make the arc-shaped belt guide arm 3 and the arc-shaped belt guide groove 28 rotate to a specific position around the rotating axis 34 under the traction of the rotating traction rope 6, so that the bundling belt passage mechanism in the circumferential bundling mechanism withdraws from the space occupied by the radial bundling mechanism during bundling, avoiding spatial position interference with the radial bundling mechanism during radial bundling.

[0062] Step seven, the system controls the sixth motor group 42 to drive the radial baling mechanism to rotate to the first radial baling position, and controls the seventh motor 47 to make the radial baling shaft 43 move straight forward to the specified position under the traction of the radial shaft forward guide rope 51 and form a closed radial baling belt guide passage with the radial baling guide arm 16.

[0063] Step eight, the radial strap 56 enters the radial baler 49 and drives the corresponding mechanism to go around the closed radial strap guide passage for one circle. After the radial baler 49 performs radial baling by controlling the No. 1 motor group 2 to drive the radial baling mechanism to move horizontally as a whole to the radial baling position, the radial baler 49 performs radial baling, and the right length laser rangefinder 62 performs real-time measurement to calibrate the position parameters of the radial baler 49 in the horizontal direction.

[0064] Step nine, after completing the radial bundling at the first position, the system drives the radial bundling mechanism to rotate to the second radial bundling position by controlling the No. 6 motor group 42 until the radial bundling of all positions of the steel coil is completed.

[0065] Step ten, after completing the radial bundling of the steel coils, the system controls the No. 8 motor 48 to make the radial bundling shaft 43 retreat to a specific position under the traction of the radial shaft retreat guide rope 50, and controls the No. 6 motor group 42 to make the radial bundling mechanism rotate to the initial position, finally completing the circumferential and radial bundling of the steel coils of this specification.
