Description

Technical Field

[0001] The present invention relates to the technical field of fiberboard conveying, and in particular to a conveying device and method for fiberboard processing. Background Art

[0002] Fiberboard, also known as density board, is a man-made board made from wood fiber or plant fiber by applying urea-formaldehyde resin or other suitable adhesives. During the processing of fiberboard, most of them require multi-station coordinated production, and the production of fiberboard is completed through processes such as fiberboard compression, cutting, and polishing.

[0003] In the process of multi-step production of fiberboard, the transportation of fiberboard is indispensable. In the prior art, belt conveyor equipment is mostly used to convey the fiberboard in processing, and the traditional belt conveyor equipment can only complete the transportation of fiberboard. In the production process of fiberboard, due to production equipment failure and changes in production speed, the fiberboard itself is prone to deformation and other problems. Most of the prior art can only confirm the quality of the finished fiberboard after the fiberboard production is completed and passed the quality inspection. When the fiberboard in the production process is deformed or defective, it will still be processed by subsequent equipment.

[0050] A conveying method for fiberboard processing, using the above-mentioned conveying device for fiberboard processing, comprises the following steps:

[0051] Step 1: Plate conveying: When conveying the fiberboard in the process, place the limit plate on one of the conveying components, start the conveying motor, and drive the fiberboard to move toward one side of the plate turning component through the rotation of the conveying roller;

[0052] Step 2: side edge detection. During the conveying process of the fiberboard, the limit motor is started to make the two limit slides move relative to each other. The movement of the limit slide drives the limit roller to move, so that the limit roller contacts the edge of one side of the fiberboard, and the limit roller positions the fiberboard in the middle of the conveying roller. After the fiberboard is positioned, the contact pressure between the limit roller and the limit plate can be detected by the tension detection sensor. When the fiberboard passes through multiple limit rollers with the movement of the conveying roller, the side flatness of the fiberboard can be detected by detecting the change in the value of the tension detection sensor.

[0053] Step 3: Plate adjustment: After the fiberboard to be processed is transported to the plate turning assembly by the conveying assembly, the clamping electric cylinder is started to clamp the fiberboard, and the turning motor is started to drive the fiberboard to move, so that the fiberboard is moved to the detection position corresponding to the flatness detection cavity;

[0054] Step 4: plane detection. When the flatness of the fiberboard surface is detected, the detection electric cylinder is started according to the thickness of the limit plate. The detection roller is driven to move by the detection electric cylinder to adjust the spacing between the two sets of flatness detection components. Then, the turning electric cylinder and the positioning motor are started synchronously. The fiberboard is driven to move toward the flatness detection component by the movement of the output end of the turning electric cylinder. The detection frame is driven to move toward the fiberboard by the positioning motor, so that the fiberboard moves in the flatness detection cavity. After the fiberboard enters the flatness detection cavity, multiple detection rollers contact the two planes of the fiberboard respectively. The contact pressure between the detection roller and the fiberboard surface can be detected and recorded by the pressure detection sensor. The flatness of the fiberboard surface can be detected by analyzing and comparing the detection values ​​of multiple pressure detection sensors.

[0055] Step 5, flip the material and discharge it. After the flatness detection mechanism has completed the flatness detection of the fiberboard surface, start the flipping motor again, and the fiberboard can be placed on another set of conveying components, and the fiberboard is transported to the next processing station through the conveying rollers.

[0056] The working principle and beneficial effects of the present invention are:

[0057] In the present invention, when conveying the plate, after placing the fiberboard on the conveying assembly, the conveying motor is started, and the output end of the conveying motor drives the conveying rollers connected thereto to rotate. When one of the conveying rollers rotates, the first toothed transmission part and the second toothed transmission part cooperate to make a plurality of conveying rollers rotate synchronously, in the same direction and at the same speed, and the fiberboard can be conveyed by the rotation of the conveying rollers.

[0058] In the present invention, during the process of conveying the fiberboard, the limit motor is started, and the output end of the limit motor drives the limit worm connected thereto to rotate, and the rotation of the limit worm drives the limit worm wheel to rotate, and the rotation of the limit worm wheel drives the limit bidirectional lead screw connected thereto to rotate, so that the two limit ball nut groups on the limit bidirectional lead screw perform relative or back-to-back movements, and the movement of the limit ball nut group drives the limit slide plate to move, and the movement of the limit slide plate drives the sliding limit part to move, so that the limit roller on the sliding limit part contacts the side of the fiberboard, and by adjusting the position of the limit roller, the limit roller positions the fiberboard at the middle position of the conveying roller, and after the limit roller contacts the fiberboard, the contact pressure between the limit roller and the fiberboard can be detected by the tension detection sensor, and when the fiberboard passes through multiple limit rollers with the movement of the conveying roller, by comparing the values ​​of each tension detection sensor through the change of the detection value of the tension detection sensor, the side flatness of the fiberboard can be intuitively detected to ensure that the fiberboard meets the production requirements;

[0059] The present invention moves one side of the fiberboard into the material clamping cavity through the conveying component, and after the position detection sensor senses the fiberboard, two material clamping electric cylinders are started synchronously, and the movement of the output end of the material clamping electric cylinder drives the material clamping plate to move, and the fiberboard is clamped and fixed by the movement of the material clamping plate. After the material clamping plate clamps the fiberboard, the material turning motor is started, and the output end of the material turning motor drives the material turning rotating rod to rotate, and the rotation of the material turning rotating rod drives the material clamping frame to rotate, and the fiberboard is driven to move by the rotation of the material clamping frame, and the fiberboard is moved to the detection position corresponding to the flatness detection cavity.

[0060] The present invention starts the material turning electric cylinder after the fiberboard is moved to the position to be detected below the flatness detection cavity, and the movement of the output end of the material turning electric cylinder drives the material turning frame to move, and the movement of the material turning frame drives the fiberboard to move toward the direction of the flatness detection component. At the same time, the detection electric cylinder is started according to the thickness of the fiberboard, and the output end of the detection electric cylinder drives the detection plate to move, and the movement of the detection plate drives the pressure detection sensor to move, and the pressure detection sensor drives the roller frame to move, and the movement of the roller frame drives the detection roller to move, so as to adjust the distance between the detection rollers in the two groups of flatness detection components, and then the positioning motor is started synchronously, and the output end of the positioning motor drives the positioning rotating rod to rotate, and the positioning rotating rod The rotation drives the adjusting worm to rotate, the rotation of the adjusting worm drives the adjusting worm wheel to rotate, the rotation of the adjusting worm wheel drives the adjusting screw to rotate, so that the adjusting ball nut group on the adjusting screw drives the detection frame to move, so that the detection frame drives the flatness detection component to move toward the fiberboard. After the fiberboard enters the flatness detection cavity, multiple detection rollers contact the two planes of the fiberboard respectively, and the contact pressure between the detection roller and the fiberboard surface can be detected and recorded by the pressure detection sensor. By analyzing and comparing the detection values ​​of multiple pressure detection sensors, the flatness of the fiberboard surface can be detected, so as to remove unqualified products and reduce excessive processing of unqualified products by production equipment;

[0061] According to the present invention, after the quality inspection of the fiberboard during the conveying process is completed, the flipping motor is started again to place the fiberboard on another set of conveying components, and the fiberboard is conveyed to the next processing station by the conveying rollers. In the actual processing and conveying process of the fiberboard, if the processing speed of the station in front of the conveying device is fast, and the processing speed of the processing station after the conveying device is slow, after the quality inspection of the fiberboard is completed by the conveying device, the fiberboard can be driven to move by the flipping electric cylinder, and with the cooperation of the flipping motor, the fiberboards in the conveying process can be stacked, which greatly reduces the floor space required during the fiberboard conveying process.
