Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboards, in particular to an automatic feeding mechanism for corrugated cardboards. Background Art

[0002] In the production and processing of corrugated cardboard, loading operations are usually done manually, which is not only labor-intensive and inefficient, but also prone to errors, affecting product quality. With the development of automation technology, automatic loading mechanisms for corrugated cardboard are gradually being used.

[0003] However, the existing feeding mechanism has deficiencies in measuring the specifications, dimensions, and weight range of corrugated cardboard, making it difficult to meet the needs of high-precision production.

[0004] Therefore, we propose an automatic feeding mechanism for corrugated cardboard. Utility Model Content

[0005] The main purpose of the utility model is to provide an automatic feeding mechanism for corrugated cardboard, which can accurately measure the specifications, dimensions and weight range of the corrugated cardboard, improve the accuracy and efficiency of feeding, and effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An automatic feeding mechanism for corrugated cardboard includes a frame, a bracket provided on the inner side of the frame, a size measuring device and a size recognition unit provided on the inner side of the bracket, the size measuring device including an image recognizer disposed opposite the size recognition unit, a first laser ranging sensor arranged in a plurality of groups and equidistantly spaced along a conveying direction on the inner wall of one side of the bracket, and a second laser ranging sensor and a third laser ranging sensor arranged in a plurality of groups and equidistantly spaced perpendicularly to the conveying direction on the inner wall of the other side and the inner wall of the top end of the bracket.

[0008] Four groups of evenly distributed installation cavities are provided inside the frame, and weight measuring units are fixedly installed on the inner walls of the bottom ends of the four groups of installation cavities. Support blocks are provided on the tops of the four groups of weight measuring units. Active rollers are connected between the inner sides of two adjacent groups of support blocks through bearings, and driven rollers are provided between the inner sides of the other two adjacent groups of support blocks. A conveyor belt is connected between the active rollers and the driven rollers, and the outer surface of the conveyor belt is provided with anti-slip grooves.

[0009] By adopting the above technical solution, when the corrugated cardboard is placed on the conveyor belt and is ready for loading, it first passes through the measuring area on the inner side of the bracket. The specification recognition unit is installed at a position diagonally above the inner wall of the bracket to read the identification code on the corrugated cardboard or use image recognition technology to identify the specifications and models of the cardboard. The image recognizer in the size measuring device is arranged opposite to the specification recognition unit to assist in obtaining the image information of the cardboard to measure the size more accurately. Multiple groups of first laser ranging sensors are arranged at equal distances along the conveying direction on the inner wall of one side of the bracket. When the cardboard moves on the conveyor belt, the distance from the front end to the rear end of the cardboard is measured in turn. As the cardboard moves forward, each first laser ranging sensor measures the distance from the cardboard at its corresponding position to the cardboard. The distance of the board is measured by recording these sequentially measured data, the fixed spacing between sensors, and the time sequence of measurements. After data processing, the length information of the cardboard can be obtained. On the inner wall on the other side of the bracket and the inner wall on the top, multiple groups of equidistantly arranged second and third laser ranging sensors are arranged perpendicular to the conveying direction. When the cardboard passes by, they work simultaneously to measure the distance from the cardboard to the sensors at different positions in the width and thickness directions. By comprehensively analyzing these simultaneously measured data and combining them with the position and spacing information of the sensors, the width and thickness of the cardboard are calculated. Through the coordinated work of various components, the precise measurement of the specifications and dimensions of the corrugated cardboard is achieved, providing accurate data support for subsequent processing.

[0010] When corrugated cardboard is placed on the conveyor belt, its weight is transferred to the weight measuring unit through the support block. Due to the four sets of evenly distributed weight measuring units, the weight of the corrugated cardboard can be measured more comprehensively and accurately. The active roller rotates, and the friction between the conveyor belt and the active roller and the driven roller drives the conveyor belt to operate, thereby realizing the transportation of the corrugated cardboard. The anti-slip texture on the outer surface of the conveyor belt can increase the friction between the corrugated cardboard and the cardboard to prevent the cardboard from slipping during transportation, ensuring smooth and accurate transportation. The driving of the active roller, the transmission of the conveyor belt and the measurement of the weight measuring unit jointly complete the transportation and weight measurement of the corrugated cardboard.

[0011] Furthermore, a first motor is fixedly mounted at one end of the frame, a slide groove is provided on the inner wall of the frame close to the first motor, a screw rod is rotatably connected inside the slide groove, and the output end of the first motor passes through the frame and is fixedly connected to the screw rod.

[0012] By adopting the above technical solution, the first motor is fixedly installed at one end of the frame. When the first motor is started, its output end begins to rotate. Since the output end of the first motor is fixedly connected to the screw rod, the rotation of the motor will drive the screw rod to rotate synchronously inside the slide groove.

[0013] Furthermore, a grabbing device is slidably connected inside the chute, and the grabbing device includes a slider threadedly connected to the screw rod, one end of the slider extends to the outside of the chute, and a mechanical arm is fixedly connected to the top end.

[0014] By adopting the above technical solution, when the first motor drives the screw to rotate, since the slider is threadedly connected to the screw, the rotational movement of the screw will be converted into a linear sliding of the slider in the slide groove. The sliding of the slider will drive the robotic arm to move along the direction of the slide groove, thereby realizing the adjustment of the position of the robotic arm to grab and place corrugated cardboard.

[0015] Furthermore, a telescopic rod is provided at the bottom end of the robotic arm away from the slider, an air pump is fixedly installed at the bottom end of the telescopic rod, and a suction cup is fixedly installed at the bottom end of the air pump.

[0016] By adopting the above technical solution, when it is necessary to grab a corrugated cardboard, the air pump generates negative pressure. Under the action of negative pressure, the suction cup closely adheres to the surface of the corrugated cardboard, thereby achieving suction and grasping of the corrugated cardboard. The telescopic rod can be extended and retracted to adjust the height of the suction cup to accommodate corrugated cards of different heights, ensuring that the cardboard can be accurately grasped at the target position. After grasping, the air pump is controlled to stop generating negative pressure or reverse the inflation, so that the suction cup separates from the corrugated cardboard, and the cardboard is released.

[0017] Furthermore, a second motor is connected to an outer wall of one side of the support block via bolts, and an output end of the second motor is connected to the active roller via a spline.

[0018] By adopting the above technical solution, when the second motor is started, its output end begins to rotate. Since the output end of the second motor is connected to the active roller through a spline, the rotation of the motor output end will be directly transmitted to the active roller, driving the active roller to rotate.

[0019] Furthermore, a control system is provided on a side of the frame away from the second motor, and the control system is electrically connected to the size measuring device, the specification recognition unit, the weight measuring unit, the first motor, the gripping device and the second motor respectively.

[0020] By adopting the above technical solution, the control system serves as the control center of the entire corrugated cardboard automatic feeding mechanism, and realizes centralized control and coordinated operation through electrical connection with various components; the control system receives measurement data from the size measuring device, specification recognition unit and weight measurement unit. Based on this data, the control system sends instructions to the first motor to control the rotation of the screw rod, thereby adjusting the position of the grasping device; at the same time, the control system also sends action signals to the grasping device to control its operation of grasping and putting down the corrugated cardboard; for the second motor, the control system determines its start, stop and speed according to production requirements and measurement data, so as to control the running speed and start and stop of the conveyor belt, thereby realizing accurate transportation and feeding of corrugated cardboard; the control system ensures the efficient, accurate and coordinated operation of the entire corrugated cardboard automatic feeding mechanism through real-time monitoring and precise control of each component.

[0021] Furthermore, support legs are fixedly installed at the four corners of the bottom end of the frame, and a loading box is provided on the inner side of one end of the frame close to the slide groove.

[0022] By adopting the above technical solution, the supporting legs play a role in stably supporting the entire mechanism; the loading box is used to store corrugated cardboard to be processed.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The utility model provides an automatic feeding mechanism for corrugated cardboard, which can accurately measure the specifications, length, width and thickness of the corrugated cardboard through the coordinated work of multiple measuring devices, including a specification recognition unit, an image recognizer, a first laser ranging sensor, a second laser ranging sensor and a third laser ranging sensor, and provides accurate and comprehensive data support for subsequent processing, which helps to improve the accuracy and quality of processing and reduce waste and resource waste caused by inaccurate size measurement.

[0025] (2) The utility model provides an automatic feeding mechanism for corrugated cardboard. When the corrugated cardboard is transported on the conveyor belt, it utilizes the drive of the active roller, the transmission of the conveyor belt and the design of the anti-slip pattern to achieve smooth and accurate transportation. At the same time, four groups of evenly distributed weight measuring units can measure the weight of the cardboard more comprehensively and accurately. This efficient transportation and stable measurement method improves the efficiency of the entire feeding process, reduces mistakes and errors in the transportation process, and ensures the smooth progress of the production process.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] In order to accurately measure the specifications, dimensions and weight range of corrugated cardboard and improve the accuracy and efficiency of feeding, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, an automatic feeding mechanism for corrugated cardboard includes a frame 1, a bracket 2 is provided on the inner side of the frame 1, and a size measuring device 3 and a size recognition unit 4 are provided on the inner side of the bracket 2. The size measuring device 3 includes an image recognizer 5 arranged opposite to the size recognition unit 4. The inner wall of one side of the bracket 2 is provided with multiple groups of first laser ranging sensors 6 arranged equidistantly along the conveying direction. The inner wall of the other side and the inner wall of the top of the bracket 2 are respectively provided with multiple groups of second laser ranging sensors 7 and third laser ranging sensors 8 arranged perpendicular to the conveying direction and equidistantly.

[0033] The interior of the frame 1 is provided with four groups of evenly distributed installation cavities 9, and the bottom inner walls of the four groups of installation cavities 9 are fixedly installed with weight measuring units 10. The tops of the four groups of weight measuring units 10 are provided with support blocks 11. The inner sides of two adjacent groups of support blocks 11 are connected with active rollers 12 through bearings, and the inner sides of the other two adjacent groups of support blocks 11 are provided with driven rollers 13. A conveyor belt 14 is connected to the active rollers 12 and the driven rollers 13, and the outer surface of the conveyor belt 14 is provided with anti-slip grooves.

[0034] During use, when the corrugated cardboard is placed on the conveyor belt and is ready for loading, it first passes through the measuring area on the inner side of the bracket 2. The specification recognition unit 4 is installed at a position diagonally above the inner wall of the bracket 2 to read the identification code on the corrugated cardboard or use image recognition technology to identify the specifications and models of the cardboard. The image recognizer 5 in the size measuring device 3 is arranged opposite to the specification recognition unit 4 to assist in obtaining the image information of the cardboard so as to measure the size more accurately. Multiple groups of first laser ranging sensors 6 are arranged at equal distances along the conveying direction on the inner wall of one side of the bracket 2. When the cardboard moves on the conveyor belt, the distance from the front end to the rear end of the cardboard is measured in turn. As the cardboard moves forward, each first laser ranging sensor 6 measures the distance from the cardboard to the rear end at its corresponding position. The distance of the board is measured by recording these sequentially measured data, the fixed spacing between sensors, and the time sequence of measurement. After data processing, the length information of the cardboard can be obtained. On the inner wall of the other side and the inner wall of the top of the bracket 2, multiple groups of second laser ranging sensors 7 and third laser ranging sensors 8 are arranged at equal distances perpendicular to the conveying direction. When the cardboard passes by, they work simultaneously to measure the distance from the cardboard to the sensors at different positions in the width and thickness directions. By comprehensively analyzing these simultaneously measured data and combining them with the position and spacing information of the sensors, the width and thickness of the cardboard are calculated. Through the coordinated work of various components, accurate measurement of the specifications and dimensions of the corrugated cardboard is achieved, providing accurate data support for subsequent processing;

[0035] When a corrugated cardboard is placed on the conveyor belt 14, its weight is transferred to the weight measuring unit 10 through the support block 11. Since there are four groups of evenly distributed weight measuring units 10, the weight of the corrugated cardboard can be measured more comprehensively and accurately. The active roller 12 rotates, and the friction between the conveyor belt 14, the active roller 12, and the driven roller 13 drives the conveyor belt 14 to operate, thereby realizing the transportation of the corrugated cardboard. The anti-slip texture on the outer surface of the conveyor belt 14 can increase the friction between the corrugated cardboard and the cardboard, preventing the cardboard from slipping during transportation, ensuring smooth and accurate transportation. The driving of the active roller 12, the transmission of the conveyor belt 14, and the measurement of the weight measuring unit 10 jointly complete the transportation and weight measurement of the corrugated cardboard.

[0036] For example, Figure 1 As shown, the utility model also includes that a first motor 17 is fixedly mounted at one end of the frame 1, a slide groove 15 is provided on the inner wall of the frame 1 close to the first motor 17, and a screw rod 16 is rotatably connected inside the slide groove 15. The output end of the first motor 17 passes through the frame 1 and is fixedly connected to the screw rod 16.

[0037] During use, the first motor 17 is fixedly mounted at one end of the frame 1. When the first motor 17 is started, its output end begins to rotate. Since the output end of the first motor 17 is fixedly connected to the screw rod 16, the rotation of the motor will drive the screw rod 16 to rotate synchronously inside the slide groove 15.

[0038] For example, Figure 1 、 Figure 4 As shown, the present invention also includes a grasping device 18 that is slidably connected to the inside of the slide 15, and the grasping device 18 includes a slider 19 that is threadedly connected to the screw rod 16, one end of the slider 19 extends to the outside of the slide 15, and a robotic arm 20 is fixedly connected to the top.

[0039] During use, when the first motor 17 drives the screw rod 16 to rotate, since the slider 19 is threadedly connected to the screw rod 16, the rotational movement of the screw rod 16 will be converted into a linear sliding of the slider 19 in the slide groove 15. The sliding of the slider 19 will drive the robotic arm 20 to move along the direction of the slide groove 15, thereby realizing the adjustment of the position of the robotic arm 20 to grab and place corrugated cardboard.

[0040] For example, Figure 1 、 Figure 4 As shown, the present invention further includes that the bottom end of the robotic arm 20 away from the slider 19 is provided with a telescopic rod 21 , the bottom end of the telescopic rod 21 is fixedly mounted with an air pump 22 , and the bottom end of the air pump 22 is fixedly mounted with a suction cup 23 .

[0041] During use, when a corrugated cardboard needs to be grabbed, the air pump 22 generates negative pressure. Under the action of the negative pressure, the suction cup 23 closely adheres to the surface of the corrugated cardboard, thereby achieving suction and gripping of the corrugated cardboard. The telescopic rod 21 can be extended and retracted to adjust the height of the suction cup 23 to accommodate corrugated cards of different heights, ensuring that the cardboard at the target position can be accurately grabbed. After the cardboard is grabbed, the air pump 22 is controlled to stop generating negative pressure or reverse the inflation, so that the suction cup 23 separates from the corrugated cardboard, thereby releasing the cardboard.

[0042] For example, Figure 1 As shown, the present invention further includes that a second motor 26 is connected to an outer wall of one side of the support block 11 via bolts, and an output end of the second motor 26 is connected to the active roller 12 via a spline.

[0043] During use, when the second motor 26 is started, its output end begins to rotate. Since the output end of the second motor 26 is connected to the active roller 12 through a spline, the rotation of the motor output end is directly transmitted to the active roller 12, driving the active roller 12 to rotate.

[0044] For example, Figure 1 As shown, the present invention also includes that a control system 24 is provided on the side of the frame 1 away from the second motor 26, and the control system 24 is electrically connected to the size measuring device 3, the specification recognition unit 4, the weight measuring unit 10, the first motor 17, the gripping device 18 and the second motor 26 respectively.

[0045] When in use, the control system 24 serves as the control center of the entire corrugated cardboard automatic feeding mechanism, and realizes centralized control and coordinated operation through electrical connection with various components; the control system 24 receives measurement data from the size measuring device 3, the specification recognition unit 4 and the weight measurement unit 10. Based on this data, the control system 24 sends instructions to the first motor 17 to control the rotation of the screw 16, thereby adjusting the position of the grabbing device 18; at the same time, the control system 24 also sends an action signal to the grabbing device 18 to control its operation of grabbing and putting down the corrugated cardboard; for the second motor 26, the control system 24 determines its start, stop and speed according to production requirements and measurement data, so as to control the running speed and start and stop of the conveyor belt 14, thereby realizing accurate transportation and feeding of the corrugated cardboard; the control system 24 ensures the efficient, accurate and coordinated operation of the entire corrugated cardboard automatic feeding mechanism through real-time monitoring and precise control of each component.

[0046] For example, Figure 1 As shown, the present invention further includes that support legs 25 are fixedly installed at the four corners of the bottom end of the frame 1, and a loading box 27 is provided on the inner side of one end of the frame 1 close to the slide 15.

[0047] When in use, the support legs 25 play a role in stably supporting the entire mechanism; the loading box 27 is used to store corrugated cardboard to be processed.

[0048] It should be noted that the present invention is an automatic feeding mechanism for corrugated cardboard, which places the corrugated cardboard to be processed in the feeding box 27, starts the first motor 17, drives the screw 16 to rotate, and makes the slider 19 slide in the slide 15, thereby adjusting the position of the robot arm 20, and the telescopic rod 21 at the bottom end of the robot arm 20 is extended and retracted to adjust the suction cup 23 to a suitable height. The air pump 22 works to generate negative pressure, so that the suction cup 23 absorbs and grabs the corrugated cardboard, and then the control system 24 controls the air pump 22 to stop the negative pressure or reverse the inflation, so that the suction cup 23 is separated from the cardboard, and the corrugated cardboard is taken out of the material box and placed on the conveyor belt 14; ... according to the measurement data. According to production needs, the second motor 26 is started to drive the active roller 12 to rotate, so that the conveyor belt 14 runs and the corrugated cardboard is transported. When it passes through the measuring area inside the bracket 2, the specification recognition unit 4 reads the identification code or performs image recognition to determine the specification and model of the cardboard. The image recognizer 5 assists in obtaining image information. The first laser ranging sensor 6 measures the length from the front end to the rear end of the cardboard in turn. The second laser ranging sensor 7 and the third laser ranging sensor 8 simultaneously measure the distance between different positions of the cardboard in the width and thickness directions. At the same time, when the corrugated cardboard moves on the conveyor belt 14, its weight is transferred to the weight measuring unit 10 through the support block 11.

Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can be further used.
