Description

Technical Field

[0001] This utility model relates to a conveying device, and more particularly to a feeding device and an unwinding feeding system. Background Technology

[0002] During the rolling process of steel coils, the coils must first be loaded onto an uncoiler for uncoiling. Currently, the methods for loading steel coils typically involve workers controlling an overhead crane to directly hoist the coils to the uncoiler, or controlling the overhead crane to place the coils onto a transfer trolley, which then moves the coils to the uncoiler. The height of the transfer trolley is then adjusted to ensure the coils reach the uncoiler. It is evident that current methods of loading steel coils rely on manual control and adjustment, resulting in low loading efficiency. Therefore, there is an urgent need for equipment that can improve the efficiency of steel coil loading. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding device and an uncoiling feeding system to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A feeding device includes: two transfer seats spaced apart in the left-right direction; a feeding mechanism having a feeding carriage movable in the front-back direction, the feeding carriage being located between the two transfer seats, the feeding carriage being provided with a support that can protrude upwards or retract downwards into the transfer seats; and a measuring mechanism including a scale grating and an indicator grating, the scale grating and the indicator grating being located on opposite sides of the two transfer seats, and the scale grating and the indicator grating forming a measuring area above the transfer seats.

[0006] This technical solution has at least the following beneficial effects: The steel coil to be uncoiled is loaded onto the transfer seats, where two transfer seats support the left and right ends of the coil respectively. At this time, the steel coil is located within the measurement area formed by the scale grating and the indicator grating within the measuring mechanism. The scale grating generates the signal required for measurement, and the indicator grating interacts with the scale grating to produce moiré fringes. Displacement measurement is achieved through changes in the moiré fringes. The scale grating and the indicator grating measure the outer diameter of the steel coil, thereby determining the center position of the coil. Then, the material handling trolley moves directly beneath the steel coil, supported by the support seats. The device moves upward and protrudes from the transfer seat, lifting the steel coil and raising it according to its center position. This allows the coil to leave the transfer seat and reach the required center position. The material carrier then moves to an external device, such as an uncoiler, where the uncoiler positions the coil. The support then moves down away from the coil, completing the loading process. By accurately measuring the size and position of the coil using a measuring grating, the support lifts the coil to the required installation height and moves it for loading. This reduces manual operation, greatly improves the efficiency of loading steel coils, and is applicable to steel coils of different sizes.

[0007] As a further improvement to the above technical solution, the measuring mechanism includes a mounting base, a rotary drive component, and a gantry frame. The mounting base is respectively provided on the side of the two intermediate seats that are far apart from each other. The left and right sides of the bottom of the gantry frame are rotatably connected to the two mounting bases. The rotary drive component drives the gantry frame and can drive the gantry frame to rotate to a vertical or horizontal state. The scale grating and the indicator grating are respectively located on the left and right sides of the gantry frame. Two transfer stations are each equipped with a mounting base on one side away from each other. The left and right sides of the bottom of the gantry are rotatably connected to the two mounting bases. When a steel coil is loaded onto the transfer station, the rotary drive drives the gantry to rotate to a horizontal position, lowering the height of the gantry along with the scale grating and indicator grating. This facilitates the transfer of the steel coil to the transfer station, improving the efficiency of loading the steel coil to the transfer station and providing better protection for the scale grating and indicator grating, preventing damage to them during the loading process. After the steel coil is loaded onto the transfer station, the rotary drive drives the gantry to rotate to a vertical position, raising the scale grating and indicator grating so that the steel coil enters the measurement area, enabling the measurement of the steel coil's dimensions.

[0008] As a further improvement to the above technical solution, at least one of the mounting bases is provided with a limiting bracket on its side. When the gantry is rotated to a vertical position, the gantry abuts against the limiting bracket. The limiting bracket can limit the rotation of the gantry, preventing excessive rotation. When the gantry is rotated to a vertical position, the gantry abuts against the limiting bracket. At this time, the limiting bracket can limit excessive rotation of the gantry, improving the accuracy of rotating the scale grating and the indicator grating into position.

[0009] As a further improvement to the above technical solution, the material handling trolley is equipped with a lifting drive component. This lifting drive component is driven and connected to the bottom center of the support. Guide pillars are connected to the bottom of the support and slidably connected to the material handling trolley in the vertical direction. Multiple guide pillars are arranged around the lifting drive component. The lifting drive component provides a vertical driving force to the support. When the steel coil needs to be lifted away from the transfer seat, the lifting drive component applies force to the center of the support, causing the support to rise. The sliding cooperation between the multiple guide pillars and the material handling trolley improves the stability of the support's upward movement. After the steel coil is loaded, the lifting drive component drives the support to move downward and reset. At this time, the multiple guide pillars also slide downward within the material handling trolley, which helps ensure the stability of the material handling trolley's downward movement.

[0010] As a further improvement to the above technical solution, the lifting drive component includes a lead screw connected between the support and the material handling trolley, and a first motor driven by the lead screw. When it is necessary to move the support up and down, the motor drives the lead screw, thereby moving the support up and down. This improves the accuracy of the support height adjustment, allowing the steel coil to move more accurately to the required height.

[0011] As a further improvement to the above technical solution, the material handling trolley is equipped with a reducer, and there are multiple first motors, which are connected to the lead screw via the reducer. When it is necessary to move the support up and down, the multiple first motors work simultaneously, driving the lead screw to rotate through the reducer. This increases the output torque, increases the load of the support on the steel coil lifting, and improves the stability of adjusting the height of the steel coil.

[0012] As a further improvement to the above technical solution, the material handling mechanism includes a guide rail located below the material handling trolley. Multiple rollers are arranged on the bottom side of the material handling trolley, and these rollers are respectively connected to the guide rail. A second motor is installed on the material handling trolley, and the second motor is driven by at least one of the rollers. When the steel coil needs to be transferred to external equipment, the second motor drives at least one roller to rotate. At this time, the roller powered by the second motor is the driving roller, and the remaining rollers are driven rollers. The multiple rollers move on the guide rail, thereby realizing the forward and backward movement of the material handling trolley.

[0013] As a further improvement to the above technical solution, a first limiting groove is provided on the top side of each of the two transfer seats. The first limiting groove can limit the steel coil, which helps to prevent the steel coil from easily falling off the transfer seat and improves the safety and stability of the steel coil placed on the transfer seat.

[0014] As a further improvement to the above technical solution, a second limiting groove is provided on the top side of the support. The second limiting groove can limit the movement of the steel coil, which helps to prevent the steel coil from easily falling off the support during the transfer process, and improves the safety and stability of the steel coil placed on the support.

[0015] An unwinding and feeding system includes the feeding equipment described above.

[0016] This technical solution has at least the following beneficial effects: In this uncoiling and feeding system, after the size and position of the steel coil are accurately measured by the measuring grating, the support lifts the steel coil to the required installation height and moves it for feeding, reducing manual operation, greatly improving the efficiency of steel coil feeding, and is applicable to steel coils of different sizes.

[0025] Reference Figure 1 and Figure 2 A feeding device includes a transfer seat 100, a feeding mechanism, and a measuring mechanism. Two transfer seats 100 are spaced apart in the left-right direction. The feeding mechanism has a feeding carriage 210 movable in the front-back direction, located between the two transfer seats 100. The feeding carriage 210 has a support 220 that can protrude upwards or retract downwards into the transfer seat 100. The measuring mechanism includes a scale grating and an indicator grating, located on opposite sides of the two transfer seats 100. The ruler grating and the indicator grating can form a measurement area above the transfer seat 100. In practical applications, the two transfer seats 100 are located on the ground, and a ground groove is opened at the gap between the two transfer seats 100. The material transfer car 210 is installed in the ground groove to adapt to the height of other equipment. Naturally, the measuring mechanism also includes a photoelectric conversion device and a grating digital display. The photoelectric conversion device is used to convert the changes of the grating into electrical signals, and the grating digital display is used to display the measurement structure. When used in conjunction with the photoelectric conversion device, it provides intuitive measurement data.

[0026] This technical solution has at least the following beneficial effects: The steel coil to be uncoiled is loaded onto the transfer seat 100, and the left and right transfer seats 100 support the left and right ends of the steel coil respectively. At this time, the steel coil is located within the measurement area formed by the scale grating and the indicator grating in the measuring mechanism. The scale grating is used to generate the signal required for measurement, and the indicator grating interacts with the scale grating to generate moiré fringes. The displacement is measured by the change of the moiré fringes. The outer diameter of the steel coil is measured by the scale grating and the indicator grating, thereby measuring the center position of the steel coil. Then, the material handling carriage 210 moves to directly below the steel coil, and the support 220 moves upward. The steel coil is moved and protrudes from the transfer seat 100, lifting it up and raising it according to its center position, so that the steel coil leaves the transfer seat 100 and the center position of the steel coil reaches the required height. Then, the material trolley 210 moves to an external device, such as an uncoiler, where the uncoiler positions the steel coil, and the support 220 can then move down to leave the steel coil, completing the loading of the steel coil. In this way, after the size and position of the steel coil are accurately measured by the measuring grating, the support 220 lifts the steel coil to the required installation height and moves it for loading, reducing manual operation and greatly improving the efficiency of steel coil loading. It can also be applied to steel coils of different sizes.

[0027] The scale grating and indicator grating within the measuring mechanism can be vertically mounted, fixed to opposite sides of two mounting bases 310. If it's necessary to move the steel coil to the transfer base 100, the coil needs to be moved forward and backward to approach the transfer base 100. However, in actual operation, there are situations where the steel coil needs to be moved left and right to approach the transfer base 100. In this case, the steel coil needs to avoid the positions of the scale grating and indicator grating during movement. Therefore, to facilitate the transfer of the steel coil to the transfer base 100, in this embodiment, the measuring mechanism includes mounting bases 310 and 310. 10. Rotary drive component 320 and gantry frame 330: The mounting base 310 is respectively provided on the side of the two intermediate transfer seats 100 that are far apart from each other. The left and right sides of the bottom of the gantry frame 330 are rotatably connected to the two mounting bases 310 respectively. The rotary drive component 320 drives the gantry frame 330 to rotate to a vertical or horizontal state. The rotary drive component 320 can be a rotary drive source such as a rotary cylinder or a motor. The scale grating and the indicator grating are respectively located on the left and right sides of the gantry frame 330. Two transfer seats 100 are respectively provided with mounting bases 310 on opposite sides. The left and right sides of the bottom of the gantry 330 are rotatably connected to the two mounting bases 310. When steel coils are fed into the transfer seat 100, the rotary drive 320 drives the gantry 330 to rotate to a horizontal state, reducing the height of the gantry 330 along with the scale grating and indicator grating. This facilitates the transfer of steel coils to the transfer seat 100, improving the efficiency of feeding steel coils to the transfer seat 100, and better protecting the scale grating and indicator grating, preventing damage to the scale grating or indicator grating during the steel coil feeding process. After the steel coil is fed into the transfer seat 100, the rotary drive 320 drives the gantry 330 to rotate to a vertical state. At this time, the scale grating and indicator grating can be raised, allowing the steel coil to enter the measurement area and realize the measurement of the steel coil's dimensions.

[0028] To ensure that the gantry 330 can be quickly and accurately rotated to a vertical position, in this embodiment, a limit bracket is provided on the side of one of the mounting bases 310. When the gantry 330 is rotated to a vertical position, it abuts against the limit bracket. In practical applications, the side of the limit bracket closest to the gantry 330 can be provided with elastic rubber, which acts as a buffer when the gantry 330 rotates close to the limit bracket. The limit bracket can limit the rotation of the gantry 330, preventing excessive rotation. When the gantry 330 is rotated to a vertical position, it abuts against the limit bracket. At this time, the limit bracket can limit the excessive rotation of the gantry 330, improving the accuracy of rotating the scale grating and indicator grating into position.

[0029] The material handling carriage 210 is equipped with a drive source that can drive the support 220 to move up and down. Specifically, the material handling carriage 210 is equipped with a lifting drive component, which is driven to the bottom side of the middle part of the support 220. The bottom side of the support 220 is connected to a guide post 230, which is slidably connected to the material handling carriage 210 in the up and down direction. Multiple guide posts 230 are arranged around the lifting drive component. For example, there are four guide posts 230, which are arranged in a rectangular shape on the material handling carriage 210. The lifting drive provides a vertical driving force to the support 220. When the steel coil needs to be lifted away from the transfer seat 100, the lifting drive applies force to the middle position of the support 220, causing the support 220 to rise. The sliding cooperation between the multiple guide posts 230 and the material handling carriage 210 improves the stability of the upward movement of the support 220. After the steel coil is loaded, the lifting drive moves the support 220 downward to reset. At this time, the multiple guide posts 230 also slide downward in the material handling carriage 210, which helps to ensure the stability of the downward movement of the material handling carriage 210.

[0030] The lifting drive component can be a pneumatic cylinder or a hydraulic cylinder. To improve the accuracy of controlling the vertical movement of the support 220, in this embodiment, the lifting drive component includes a lead screw 241 connected between the support 220 and the feed trolley 210, and a first motor 242 driven by the lead screw 241. Naturally, the lead screw 241 includes a nut rotating joint and a screw sliding joint. The nut rotating joint is rotatably connected to the feed trolley 210, and the nut rotating joint and the screw sliding joint are connected by a threaded connection. The top end of the screw sliding joint is connected to the bottom side of the support 220. The first motor 242 drives the nut rotating joint to rotate. When it is necessary to move the support 220 up and down, the motor drives the lead screw 241, thereby moving the support 220 up and down. This improves the accuracy of height adjustment of the support 220, allowing the steel coil to move more accurately to the required height.

[0031] In the above embodiment, there may be only one first motor 242. However, to increase the output torque of the lead screw 241, a reducer is provided on the material handling carriage 210 in this embodiment. There are multiple first motors 242, which are connected to the lead screw 241 via the reducer. In practical applications, the reducer can be a planetary gear reducer. The output ends of the multiple first motors 242 are respectively connected to main gears, which mesh at different positions on the planetary gear reducer. When it is necessary to move the support 220 up and down, the multiple first motors 242 work simultaneously, driving the lead screw 241 to rotate via the reducer. This increases the output torque, increases the load of the support 220 on the steel coil lifting, and improves the stability of adjusting the height of the steel coil.

[0032] The material handling mechanism has a drive source that can drive the material handling carriage 210 to move back and forth. For example, a cylinder, hydraulic cylinder or electric lead screw 241 can be used to drive the material handling carriage 210 to move. In this embodiment, the material handling mechanism includes a guide rail 251 located below the material handling carriage 210. A plurality of rollers 252 are provided on the bottom side of the material handling carriage 210. The plurality of rollers 252 are respectively connected to the guide rail 251. A second motor 253 is provided on the material handling carriage 210. The second motor 253 is drivenly connected to at least one of the rollers 252. When the steel coil needs to be transferred to the external equipment, the second motor 253 drives at least one roller 252 to rotate. At this time, the roller 252 powered by the second motor 253 is the driving wheel, and the other rollers 252 are driven wheels. Multiple rollers 252 move on the guide rail 251, thereby realizing the forward and backward movement of the material handling carriage 210. In practical applications, multiple guide rails 251 can be arranged side by side. For example, two guide rails 251 are arranged at intervals, and two rollers 252 are respectively arranged on the material handling carriage 210 at the positions corresponding to the two guide rails 251. At this time, the second motor 253 drives two of the rollers 252, while the other two rollers 252 are driven wheels.

[0033] To improve the stability of the steel coil placed on the transfer seat 100, in this embodiment, a first limiting groove 110 is provided on the top side of each of the two transfer seats 100. The first limiting groove 110 can limit the steel coil, which helps to prevent the steel coil from falling off the transfer seat 100 and improves the safety and stability of the steel coil placed on the transfer seat 100.

[0034] Similarly, a second limiting groove 221 is provided on the top side of the support 220. The second limiting groove 221 can limit the steel coil, which helps to prevent the steel coil from falling off the support 220 during the transfer of the steel coil, and improves the safety and stability of the steel coil placed on the support 220.

[0035] An uncoiling and feeding system includes the aforementioned feeding equipment and an uncoiling machine. The uncoiling machine has two uncoiling shafts that can move closer to or further away from each other, and the feed carriage 210 can move to a position below the two uncoiling shafts.

[0036] In this uncoiling and feeding system, the size and position of the steel coil are accurately measured by a measuring grating, and then the support 220 lifts the steel coil to the required installation height and moves it for feeding. This reduces manual operation, greatly improves the efficiency of steel coil feeding, and is applicable to steel coils of different sizes.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
