Description

Technical Field

[0001] The utility model belongs to the technical field of uncoilers, in particular to a steel coil positioning device used for uncoilers. Background Art

[0002] The uncoiler is a special equipment for leveling metal plates. It is used to level steel plates. When using the uncoiler, you need to first insert the tensioning structure into the inner hole of the steel coil, and then rotate it in cooperation with the straight head machine to lower the head of the steel strip and send it into the leveling machine. In order to ensure that the tensioning structure can align with the inner hole of the steel coil, during the steel coil loading process, the operator needs to manually adjust the position of the steel coil so that the center of the steel coil is aligned with the tensioning structure before it is transported to the tensioning structure.

[0003] However, manual alignment is not only time-consuming and labor-intensive, but also prone to errors. Operators also need to spend a lot of time aligning a single steel coil and are unable to align multiple steel coils at the same time, which greatly affects production efficiency.

[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of the steel coil positioning device for the uncoiler provided by the utility model. The steel coil positioning device for the uncoiler includes an adjustment component 10, a distance measuring component 20 arranged on the adjustment component 10, and a mounting groove 30 for accommodating the adjustment component 10. The steel coil positioning device for uncoiler also includes some other functional modules, such as a driving component and a controller arranged on one side of the adjustment component 10, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0016] It should be noted that Figure 1 The adjusting assembly 10 moves to one end close to the steel coil uncoiler 40 .

[0017] The adjustment assembly 10 includes a horizontally arranged slide rail 11, a transport platform 12 slidably arranged on the slide rail 11, at least one cylinder 13 vertically inserted on the transport platform 12, a positioning platform 14 fixedly arranged on the top of the two cylinders 13, and two positioning rods 15 horizontally and spaced apart on the top of the positioning platform 14.

[0018] The slide rails 11 are parallel to the ground and are spaced apart. The extension direction of the slide rails 11 is consistent with the direction of the line from the steel coil unloading place to the steel coil uncoiler 40. The slide rails 11 are fixedly arranged on the mounting platform 31, respectively. Therefore, a steel coil unloading place and a steel coil uncoiler 40 are respectively arranged at both ends of the slide rails 11. The steel coil rolls from the steel coil unloading place to the transport platform 12, and is transported to the steel coil uncoiler 40 along the slide rails 11. The tensioning structure 41 of the steel coil uncoiler 40 will be directly inserted into the steel coil. It should be noted that the steel coil uncoiler 40 and the steel coil unloading place are both technical contents well known to those skilled in the art, and their structures are not the main contents of the present utility model, so they will not be repeated here. The steel coil unloading place is Figure 1 Located on the right side of the slide rail 11.

[0019] The transport platform 12 includes a main body 121 , at least two pairs of wheels 122 disposed on both sides of the main body 121 , and a motor 123 disposed on the main body 121 . .

[0020] The wheel bodies 122 are respectively mounted in a rolling manner on the slide rails 11. A blocking ring 124 is provided on the side of each pair of wheel bodies 122 that are close to each other. The diameter of the blocking ring 124 is larger than the diameter of the wheel body 122, and the edge of the ring body is located on the inner side of the two slide rails 11 that are close to each other, so as to position the wheel body 122 and prevent the wheel body 122 from derailing. The motor 123 drives the wheel body 122 to rotate forward or reverse, thereby pushing the transport platform 12 to move back and forth along the slide rail 11 to achieve the effect of transporting steel coils. The structure and principle of the motor 123 driving the wheel body 122 to rotate are prior art and will not be repeated here.

[0021] The cylinder 13 is used to drive the positioning platform 14 to rise and fall, so that the center height of the steel coil located on the top of the positioning platform 14 is the same as the height of the tensioning structure of the steel coil uncoiler, so that when the steel coil moves to the end of the slide rail 11, the tensioning structure of the steel coil uncoiler can be directly inserted into the steel coil. The number of the cylinders 13 is at least 1. In this embodiment, the number of the cylinders 13 is 3 and includes a main cylinder 131 and two auxiliary cylinders 132 symmetrically arranged on both sides of the main cylinder 131, so as to ensure that the cylinder 13 drives the positioning platform 14 to rise and fall more stably.

[0022] The steel coil is placed on the top of the positioning platform 14. The extension direction of the two positioning rods 15 is the same as the extension direction of the slide rail 11. A rubber layer is provided on the surface of the positioning rod 15, so that when the steel coil is placed on the positioning rod 15, it has a certain buffering effect. At the same time, the rubber layer can also increase the friction between the steel coil and the steel coil, so as to prevent the steel coil from moving forward and backward during the movement of the positioning platform 14.

[0023] The distance measuring assembly 20 includes at least one steel coil length detection assembly 21 disposed on both sides of the slide rail 11 , and at least one pair of height detection assemblies 22 disposed on both sides of the slide rail 11 .

[0024] The steel coil length detection component 21 is a pair of photoelectric sensors respectively arranged on both sides of the slide rail 11. The laser direction of the photoelectric sensor is perpendicular to the extension direction of the slide rail. When in use, the photoelectric sensor continuously detects, and when the steel coil passes through the photoelectric sensor, the steel coil will cover the photoelectric sensor until the steel coil completely passes through the photoelectric sensor 211. The controller can calculate the length of the steel coil by calculating and processing the time when the photoelectric sensor is covered and the moving speed of the transport platform at this time.

[0025] The height detection device 22 includes two mounting seats 221 symmetrically mounted on both sides of the slide rail 11 , and three pairs of infrared sensors 222 installed on the mounting seats 221 at intervals along the height direction.

[0026] Each pair of infrared sensors 222 is arranged at intervals. When in use, the transport platform 12 first measures the distance through the steel coil length detection component 21. After the control system calculates the length of the steel coil, it controls the transport platform 12 to align the length center of the steel coil with the infrared sensor 222. By lifting the transport platform 12, the steel coil can block the infrared sensor 222 in turn, and then the diameter length of the steel coil can be calculated according to the blocking situation, so that the position of the positioning platform 14 can be adjusted according to the diameter length, so that the axis of the steel coil is aligned with the tensioning structure of the steel coil unwinding machine. Since the steel coil unwinded by the unwinding machine has various specifications and the diameter of the steel coil is not uniform, the three groups of infrared sensors 222 are set to be applicable to steel coils of various sizes as much as possible. When the diameter of the steel coil is small, the two pairs of infrared sensors 222 located at the bottom are used. When the diameter of the steel coil is large and exceeds the infrared sensor 222 at the bottom, the two infrared sensors 222 located at the top are used.

[0027] Two mounting platforms 31 are respectively horizontally provided on the side walls of the mounting groove 30 for supporting the adjustment assembly 10. The mounting platforms 31 are spaced apart from the bottom of the mounting groove 30.

[0028] When in use, first place the steel coil between the two positioning rods 15 to locate the horizontal position of the steel coil, then the transport platform 12 moves past the photoelectric sensor 211 to calculate the length of the steel coil, when the transport platform 12 passes through the height detection component 22, the axis height of the steel coil is detected and the positioning platform 14 is adjusted to rise and fall by the cylinder 13, so that the axis of the steel coil is now completely aligned, finally the transport platform 12 transports the steel coil to the front of the tensioning structure of the steel coil uncoiler and stops moving, at which time the operator manually observes whether it is aligned, and after confirming the alignment, the transport platform 12 can be controlled to continue moving and complete the installation.

[0029] Compared with the prior art, the steel coil positioning device for the uncoiler provided by the utility model can locate the position of the steel coil in the horizontal direction by setting the two positioning rods 15, and can detect the diameter length of the steel coil by setting three pairs of infrared sensors 222 arranged along the height direction, and then drive the positioning platform 14 to rise and fall through the cylinder 13, so that the axis of the steel coil is aligned with the axis of the tensioning structure of the steel coil uncoiler, thereby realizing automatic alignment. The operator only needs to visually check whether the steel coil is aligned before inserting the tensioning structure of the steel coil uncoiler, which allows one operator to simultaneously supervise multiple uncoilers, thereby improving production efficiency.

Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
