Description

Technical Field

[0001] This invention relates to the field of inkjet printing control technology, and in particular to a steel coil truss-type self-positioning laser inkjet printing device and method. Background Technology

[0002] Currently in steel mills, steel strip coils are fed into the finished product conveyor by a coiling machine. The finished product conveyor then sends the steel strip coils to an automatic circumferential bundling machine for bundling. After bundling, the coils are transported to the bulk bundling area by a transport conveyor. A steel-turning device flips the coils upright and sends them into a collection device for further winding. Finally, manual coding is performed. Manual coding is labor-intensive, costly, and poses a risk of burns. In addition, the ink used for coding contains harmful vapors, which affect the health of the operators. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a strip steel coil truss type self-positioning laser inkjet printing device and method.

[0004] To solve the above technical problems, the technical solution of the present invention is as follows: A steel coil truss-type self-positioning laser printing device includes: Conveyor rollers are used to convey steel coils. A truss assembly is fixedly installed on one side of the conveyor roller conveyor; A laser printing device is movably mounted on the truss assembly; The conveyor roller is located directly below the moving path of the laser printing device.

[0005] As a preferred embodiment of the steel coil truss self-positioning laser inkjet printing device of the present invention, the truss assembly includes a column, a support frame fixedly installed on the upper end of the column, a first slide rail fixedly installed on the support frame, a movable beam slidably installed on the first slide rail, a second slide rail fixedly installed on the movable beam, and a movable seat slidably installed on the second slide rail. The extension direction of the first slide rail is perpendicular to the conveying direction of the conveying roller conveyor, the length direction of the moving beam and the extension direction of the second slide rail are both parallel to the conveying direction of the conveying roller conveyor, and the laser printing device is fixedly installed on the moving base.

[0006] In a preferred embodiment of the steel coil truss-type self-positioning laser printing device of the present invention, a lifting drive device is fixedly installed on the movable seat, and the laser printing device is drivenly connected to the lifting drive device.

[0007] As a preferred embodiment of the strip coil truss type self-positioning laser printing device of the present invention, a laser rangefinder is fixedly installed on the laser printing device, the laser rangefinder faces the conveyor roller, and the laser emitted by the laser rangefinder extends in the horizontal direction.

[0008] In a preferred embodiment of the truss-type self-positioning laser printing device for strip coils according to the present invention, a laser sensor for detecting the position of the strip coil is fixedly installed on the side of the conveyor roller away from the truss assembly, and the laser sensor is directly opposite the truss assembly.

[0009] As a preferred embodiment of the steel coil truss-type self-positioning laser printing device of the present invention, a protective fence is provided around the truss assembly.

[0010] The present invention also provides a strip coil truss-type self-positioning laser printing method, which is based on the above-mentioned strip coil truss-type self-positioning laser printing device, comprising: The steel strip coils to be printed are conveyed by conveyor rollers; Once the laser sensor detects that the strip coil has been conveyed to the predetermined position, the conveyor rollers stop operating. The laser printing device moves along the truss, while the laser rangefinder measures the distance between the laser printing device and the strip steel coil in real time, and controls the laser printing device to stop moving when the distance between the laser printing device and the strip steel coil is the smallest. The laser printing device is raised and lowered by a lifting drive device, and the upper end face of the steel coil is determined by a laser rangefinder. The laser printing device is moved downward a preset distance by a lifting drive device, and then the laser printing device prints on the steel strip coil. After printing is complete, control the laser printing device to reset.

[0011] In a preferred embodiment of the strip steel coil truss self-positioning laser inkjet printing method of the present invention, the preset distance is 20mm.

[0012] The beneficial effects of this invention are: (1) The present invention drives the laser printing device to move along the XYZ axis by means of the truss assembly, so that the laser printing device can automatically move to the target position to print on the strip steel coil, thereby realizing the automation of the printing operation, which not only improves the work efficiency, but also effectively solves the problem of the damage to the operator caused by the inkjet paint.

[0013] (2) In this invention, a laser rangefinder is fixedly installed on the laser printing device. The laser rangefinder faces the side where the conveyor roller is located, and the laser emitted by the laser rangefinder extends in the horizontal direction. During the movement of the laser printing device along the XYZ axis, the distance between the laser printing device and the strip coil can be measured in real time by the laser rangefinder, thereby determining whether the laser printing device has moved to the target position.

[0014] (3) In this invention, a laser sensor for detecting the position of the steel strip coil is fixedly installed on the side of the conveyor roller away from the truss assembly. The laser sensor is directly opposite the truss assembly. As the steel strip coil moves on the conveyor roller, the laser sensor detects the position of the steel strip coil in real time. When the steel strip coil enters the detection area of ​​the laser sensor, it indicates that the steel strip coil has moved to the target position, which is within the area directly opposite the truss assembly. At this time, controlling the conveyor roller to stop running will allow the steel strip coil to remain at the target position, facilitating subsequent inkjet printing operations on the steel strip coil.

[0015] (4) When printing on the strip coil, the present invention controls the laser printing device to stop moving when the distance between the laser printing device and the strip coil is the smallest. Then, the laser printing device is driven to rise and fall by the lifting drive device, and the upper end face of the strip coil is determined by the laser rangefinder. Then, the laser printing device is driven to move down 20mm by the lifting drive device, and then the laser printing device is printed on the strip coil. This ensures that the laser printing device prints on the target printing position of the strip coil and ensures the integrity of the printing information. Attached Figure Description

Detailed Implementation

[0018] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] Figure 1 This is a schematic diagram of the truss-type self-positioning laser printing device for strip steel coils provided in an embodiment of this application. The device includes a conveyor roller conveyor 1, a truss assembly 2, and a laser printing device 3. The laser printing device 3 moves along the truss assembly 2 in the X, Y, and Z axes, allowing it to be moved to the target position for printing on the strip steel coil.

[0020] Specifically, conveyor roller 1 is used to convey the strip steel coil to be printed.

[0021] A truss assembly 2 is fixedly mounted on one side of the conveyor roller conveyor 1. The truss assembly 2 includes four vertically extending columns 4, forming a rectangle. A rectangular support frame 5 is fixedly mounted on the upper end of each column 4. Two first slide rails 6 are fixedly mounted on the support frame 5, located on opposite sides of the support frame 5, with their extension direction perpendicular to the conveying direction of the conveyor roller conveyor 1. Moving beams 7 are slidably mounted on the two first slide rails 6, their length direction parallel to the conveying direction of the conveyor roller conveyor 1. A second slide rail 8 is fixedly mounted on the moving beam 7, its extension direction also parallel to the conveying direction of the conveyor roller conveyor 1. A movable seat 9 is slidably mounted on the second slide rail 8, and a lifting drive device 10 is fixedly mounted on the movable seat 9. The laser printing device 3 is driven by the lifting drive device 10. When the lifting drive device 10 operates, it can drive the laser printing device 3 to rise and fall.

[0022] See Figure 1 A protective fence 12 is fixedly installed around the truss assembly 2 to prevent unauthorized personnel from entering the area where the truss assembly 2 is located.

[0023] Understandably, the moving seat 9 moves along the second slide rail 8, which in turn drives the laser printing device 3 to translate along the X-axis. The moving beam 7 moves along the first slide rail 6, which in turn drives the laser printing device 3 to translate along the Y-axis. By using the lifting drive device 10 to lift the laser printing device 3, the translation of the laser printing device 3 along the Z-axis is achieved.

[0024] It should be noted that the conveyor roller 1 is located directly below the moving path of the laser printing device 3, ensuring that the laser printing device 3 can move to the target position along the three axes mentioned above, thereby performing inkjet printing on the strip steel coil.

[0025] Preferably, a laser rangefinder is fixedly mounted on the laser printing device 3. The laser rangefinder faces the side where the conveyor roller 1 is located, and the laser emitted by the laser rangefinder extends horizontally. As the laser printing device 3 moves along the XYZ axis, the distance between the laser printing device 3 and the strip coil can be measured in real time by the laser rangefinder, thereby determining whether the laser printing device 3 has moved to the target position.

[0026] See Figure 1 Since the steel strip coil is laid flat on the conveyor roller 1 during the conveying process, the side of the steel strip coil facing the truss is an arc surface. When the distance between the laser rangefinder and the steel strip coil is minimized, it indicates that the laser printing device 3 has moved to the target position in the horizontal direction. Then, by controlling the laser printing device 3 to move up and down in the vertical direction, the laser printing device 3 can be moved to the target printing station.

[0027] Additionally, a laser sensor 11 for detecting the position of the steel strip coil is fixedly installed on the side of the conveyor roller 1 away from the truss assembly 2. This laser sensor 11 is directly opposite the truss assembly 2. As the steel strip coil moves along the conveyor roller 1, the laser sensor 11 continuously monitors its position. When the steel strip coil enters the detection area of ​​the laser sensor 11, it indicates that the steel strip coil has moved to the target position, which is now within the area directly opposite the truss assembly 2. At this point, controlling the conveyor roller 1 to stop operation allows the steel strip coil to remain at the target position, facilitating subsequent printing operations.

[0028] This application also provides a strip coil truss-type self-positioning laser printing method, which is based on the above-mentioned strip coil truss-type self-positioning laser printing device. The method specifically includes the following steps: Step S101: The strip steel coil to be printed is conveyed through conveyor roller 1; Step S102: When the laser sensor 11 detects that the strip coil has been conveyed to the predetermined position, the conveyor roller 1 stops running; Step S103: The laser printing device 3 moves along the truss, while the laser rangefinder measures the distance between the laser printing device 3 and the strip steel coil in real time, and controls the laser printing device 3 to stop moving when the distance between the laser printing device 3 and the strip steel coil is the smallest. Step S104: The laser printing device 3 is raised and lowered by the lifting drive device 10, and the upper end face of the steel coil is determined by the laser rangefinder. Step S105: The lifting drive device 10 drives the laser printing device 3 to move downward by 20mm, and then the laser printing device 3 prints on the steel strip. Step S106: After printing is completed, control the laser printing device 3 to reset. At the same time, control the conveyor roller 1 to continue running, transporting the printed strip to the next station, and transporting the next strip to be printed to the printing station.

[0029] Therefore, the technical solution of this application drives the laser printing device 3 to move along the XYZ axis through the truss assembly 2, so that the laser printing device 3 can automatically move to the target position to print on the strip steel coil, realizing the automation of the printing operation, which not only improves work efficiency, but also effectively solves the problem of the damage to operators caused by inkjet paint.

[0030] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
