Description

Technical Field

[0001] The present invention relates to the field of automated machinery, and in particular to a cardboard stacking system and a method for using the same. Background Art

[0002] The existing palletizing devices all use conveyor belts to directly transport materials to the designated area, and then use robots to grab and clamp the materials to the pallet for placement. The existing stacking is achieved by relying on the flexibility of the robots. There is a kind of cardboard that needs to be stacked. Three or four cardboards can be stacked on a pallet in the same layer. This requires the robot to move over a large range and absorb the materials by means of suction cups. However, when the robot controls the cardboard to make angle or unknown adjustments, the speed needs to be slowed down a lot, otherwise the cardboard will fall off during the adjustment process due to insufficient suction, so the work efficiency is relatively low. Summary of the invention

[0003] The main object of the present invention is to provide a cardboard stacking system and a method of using the same.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A cardboard stacking system comprises a feeding conveying device, a visual inspection device is mounted above the feeding end of the feeding conveying device, the feeding conveying device comprises a first feeding section, a second feeding section, a third feeding section and a fourth feeding section, an adjustment avoidance groove is opened at the center of the second feeding section, a rotation adjustment device is slidably mounted in the adjustment avoidance groove, a stacking device is mounted above the discharging end of the feeding conveying device, the stacking device comprises a gantry, a transverse adjustment device fixedly mounted on the gantry, a longitudinal adjustment device fixedly mounted on the transverse adjustment device, a material clamping fixing plate fixedly mounted on the longitudinal adjustment device, a material clamping device fixedly mounted on the lower end surface of the material clamping fixing plate and a limiting component, the limiting component comprises a center limiting component and an edge limiting component.

[0006] Furthermore, the rotation adjustment device includes a first lifting device, a rotating motor and an adjustment plate. The rotating motor is fixedly mounted on the first lifting device, and the adjustment plate is fixedly mounted on the rotation output end of the rotating motor.

[0007] Furthermore, the third loading section includes a lifting and fixing frame, a second lifting device, a second conveyor belt, a power component and a first sensing component. The lifting and fixing frame is fixedly installed with the second lifting device, the second conveyor belt is fixedly installed with the second lifting device, the second conveyor belt is fixedly connected with the power component, and the first sensing component is fixedly installed on the second conveyor belt.

[0008] Furthermore, the conveying direction of the second conveyor belt is perpendicular to the conveying directions of the first feeding section, the second feeding section and the fourth feeding section, and the conveying direction width of the second conveyor belt is smaller than the minimum width of the conveying cardboard.

[0009] Furthermore, the center limit assembly includes a first longitudinal translation adjustment device, a first transverse adjustment device and a center limit frame. The first longitudinal translation adjustment device is fixedly installed at the center of the lower end surface of the clamping fixing plate. The first longitudinal translation adjustment device is connected to the first transverse adjustment device. The first transverse adjustment device is connected to the center limit frame. The center limit frame is an upright cross or T-shaped one.

[0010] Furthermore, the edge limiting assembly includes four linear slide rails respectively fixedly mounted at the centers of four sides of the lower end surface of the clamping fixing plate, and the linear slide rails are respectively connected to limiting plates.

[0011] Furthermore, a material blocking assembly is fixedly installed below the fourth feeding section, and the material blocking assembly includes multiple material blocking plates and a fourth lifting device for lifting the material blocking plates.

[0014] Furthermore, a method for using the cardboard stacking system is characterized by comprising the steps of:

[0015] S1, placing the cardboard on the first feeding section mechanically or manually, after the visual inspection device above the first feeding section detects the material, it takes a photo of it, and processes the photographed photo information to obtain its approximate edge information, including rotation angle information and position information on the first feeding section;

[0016] S2, after the information is uploaded, the material is conveyed forward to the second feeding section.

The clamping device directly grabs the arranged multiple materials and moves them to the tray. The work efficiency is high and the error of material falling off is not likely to occur. The work efficiency is improved while the probability of error is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0027] Referring to Figures 1-2, a cardboard stacking system includes a loading and conveying device 1, a visual inspection device 2 is mounted above the feeding end of the loading and conveying device 1, the loading and conveying device 1 includes a first loading section 11, a second loading section 12, a third loading section 13 and a fourth loading section 14, an adjustment avoidance groove is opened at the center of the second loading section 12, a rotation adjustment device 15 is slidably installed in the adjustment avoidance groove, a stacking device 3 is mounted above the discharge end of the loading and conveying device 1, the stacking device 3 includes a gantry 31, a transverse adjustment device fixedly mounted on the gantry 31, a longitudinal adjustment device 32 fixedly mounted on the transverse adjustment device, a clamping plate 33 fixedly mounted on the longitudinal adjustment device 32, a clamping device 34 fixedly mounted on the lower end surface of the clamping plate 33 and a limit assembly, the limit assembly includes a center limit assembly 36 and an edge limit assembly 37.

[0028] The rotation adjustment device 15 includes a first lifting device, a rotating motor and an adjustment plate. The rotating motor is fixedly mounted on the first lifting device, and the adjustment plate is fixedly mounted on the rotation output end of the rotating motor.

[0029] The third feeding section 13 includes a lifting fixed frame, a second lifting device, a second conveyor belt, a power component and a first sensing component. The lifting fixed frame is fixedly installed with the second lifting device, the second conveyor belt is fixedly installed with the second lifting device, the second conveyor belt is fixedly connected with the power component, and the first sensing component is fixedly installed on the second conveyor belt.

[0030] The first sensing component is used to sense the material loading progress and determine whether the material has arrived on the second conveyor belt on the third loading section. After sensing that the material has arrived at the designated position, the image obtained by the visual detection device on the first loading section is combined with the rotation axis of the rotating motor of the second loading section to determine the position information of the material arriving on the adjustment plate. The visual detection device can also be directly placed above the adjustment plate to determine the data that need to be adjusted for the angle and direction of the material, which is used to adjust the angle and direction of the material and obtain the position of the material on the conveyor belt after adjustment. When the material is relatively close to the edge or needs to be close to one side of the conveyor belt, after determining the position of the material on the conveyor belt through the image, the third loading section is used to adjust the horizontal position of the material on the conveyor belt, thereby achieving specific positioning of the material.

[0031] The first loading section is used to determine the information of the material on the conveyor belt, the second loading section is used to adjust the angle of the material, and the third loading section is used to adjust the horizontal position of the material on the conveyor belt. In the material conveying process of the present application, since the product may need to be loaded horizontally or vertically, the horizontal length of the material on the conveyor belt varies. In order to standardize the specific position of the material on the conveyor belt, it is necessary to adjust the material in the horizontal direction of the conveyor belt through the third loading section. After the sensing device senses that the center of the material is at the center of the horizontal conveyor belt, the second horizontal conveyor belt is raised by the second lifting device, and then the second conveyor belt is started to adjust the material horizontally to achieve the final positioning of the material. Since the width of the third loading section is smaller than the minimum width of the material, after the second lifting device of the third loading section descends to a certain height, one end or both ends of the material will dock with the conveyor belts at its front and rear ends to achieve normal loading.

[0032] The conveying direction of the second conveyor belt is perpendicular to the conveying directions of the first feeding section 11, the second feeding section 12 and the fourth feeding section 14, and the conveying direction width of the second conveyor belt is smaller than the minimum width of the conveyed cardboard.

The first longitudinal translation adjustment device is fixedly installed at the center of the lower end surface of the clamping fixing plate 33. The first longitudinal translation adjustment device is connected to the first transverse adjustment device. The first transverse adjustment device is connected to the center limit frame 363. The center limit frame 363 is an upright cross or T-shaped one.

[0034] The edge limiting assembly 37 includes four linear guide rails 371 respectively fixedly mounted at the centers of four sides of the lower end surface of the clamping fixing plate 33 , and the linear guide rails 371 are respectively connected to limiting plates 372 .

[0035] A material blocking assembly 16 is fixedly installed below the fourth feeding section 14, and the material blocking assembly 16 includes multiple material blocking plates and a fourth lifting device for lifting the material blocking plates. The material blocking plates are respectively connected to the fourth lifting device below, and the fourth lifting device includes three lifting cylinders and guide rails matched with the lifting cylinders.

[0036] A third lifting device is also fixedly mounted on the gantry 31 , and the third lifting device is placed between the lateral adjustment device and the gantry 31 .

[0037] The clamping device 34 includes no less than four groups of suction discs, which are respectively arranged at the four corners of the clamping fixing plate 33 , and the clamping device 34 is arranged between the central limiting component 36 and the edge limiting component 37 .

[0038] A method for using a cardboard stacking system, comprising the steps of:

[0039] S1, placing the cardboard on the first loading section 11 mechanically or manually, after the visual inspection device 2 above the first loading section 11 detects the material, it takes a photo of it, and processes the photographed photo information to obtain its approximate edge information, including rotation angle information and position information on the first loading section 11;

[0040] S2, after the information is uploaded, the material is conveyed forward to the second feeding section 12, and the rotary adjustment device 15 of the second feeding section 12 determines whether the material needs to be adjusted according to the photo information. If adjustment is required, the adjustment plate is lifted upward by the lifting device of the rotary adjustment device 15, so that the material is separated from the conveying track, and the adjustment plate is controlled by the rotary motor to rotate the specified angle to achieve the alignment and adjustment of the material angle and direction. After the angle or direction adjustment is completed, the adjustment plate drops to its original position, and then the material continues to be conveyed forward. If the angle and direction meet the requirements, the rotary adjustment device 15 remains in place and the material continues to be conveyed forward;

[0041] S3, after the material is transferred to the top of the third loading section 13, it is determined whether its position on the conveyor belt needs to be adjusted according to the photo information to facilitate subsequent loading. If adjustment is required, the third loading section 13 adjusts the material position according to the material position information, and adjusts it through forward or reverse transmission of the third loading section 13;

[0042] S4, after the material is adjusted in the third feeding section 13, it enters the fourth feeding section 14, which is the discharging area. The baffle plate in the discharging area blocks the material according to the required material combination mode, so as to facilitate the material to be combined into the shape before stacking;

[0043] S5, multiple materials are adsorbed simultaneously by the stacking device 3, moved to the top of the tray, and unloaded. After unloading, the edges of the materials are aligned by the limiting component to prevent the materials from being skewed.

[0044] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment.
