Description

Technical Field

[0001] This utility model relates to the field of glass fiber production and processing technology, and in particular to an automatic yarn picking device for glass fiber with adaptive three-level adjustment. Background Technology

[0002] The yarn picking process of the yarn replenishment machine in the short-cutting workshop of Jushi Group Co., Ltd. is a mechanically controlled process using a cylinder, which can be broken down into the following steps:

[0003] 1. Cylinder Control: The cylinder is a key actuator in the yarn-picking process of the yarn replenishment machine. By controlling the stroke of the cylinder, the rising height of the plate can be adjusted to ensure that the plate can accurately contact and lift the yarn bundle;

[0004] 2. Tile: The tile is located below the yarn ball and contacts the side of the yarn ball to ensure that the yarn ball can be lifted smoothly and without damage during the yarn picking process;

[0005] 3. Stroke adjustment: The stroke of the cylinder that pushes the tile upward is determined by the cylinder stroke. The tile is lifted off the yarn frame, realizing the separation of the yarn ball from the yarn machine.

[0006] 4. Separation Mechanism: As the cylinder pushes, the tile lifts the yarn ball off the spinning wheel, creating a gap between them and thus separating them. This process requires the tile's stroke and speed to be matched with the weight of the yarn ball to avoid damage.

[0007] However, the following problems may occur during the yarn removal process: 1. Small yarn balls may be impossible to remove from the yarn cart, requiring manual handling at the central rotating platform. 2. Medium-sized yarn balls may fall and damage themselves during the removal process due to insufficient friction between the tiles and the yarn balls.

[0008] After investigation, the following reasons were found to be the causes of the above problems:

[0009] 1. Because the automatic unloading machine in the front-end drawing workshop uses servo motor torque control to automatically pick up yarn from the drawing machine head and then automatically place it on the yarn cart, the entire process is fully automated. Different product types and yarn types result in different sizes of yarn spools drawn by the drawing machine. However, the offline chopped yarn rack is a matrix-integrated system, and the offline chopped yarn unloading machine cannot automatically adapt to the tile height based on the size of each yarn spool.

[0010] 2. For small yarn balls with a diameter of less than 20cm, it is impossible to pick up the small yarn balls due to insufficient cylinder stroke and the limited distance between the two tiles of each layer of yarn frame.

[0011] Therefore, an automatic yarn ball picking adaptive three-level adjustment device was designed to solve the above problems. Utility Model Content

[0012] The purpose of this invention is to provide an automatic fiberglass yarn picking device with adaptive three-level adjustment.

[0013] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

A distance sensor is fixedly installed on each mounting bracket.

[0015] Furthermore, each movable yarn frame base is equipped with 12 tiles, which are installed in four layers, with 3 tiles installed in each layer.

[0016] Furthermore, three vertical cylinders are installed on the yarn frame crossbeam, and the three vertical cylinders are installed at equal intervals.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0033] like Figure 1As shown, an automatic yarn-picking adaptive three-level adjustable yarn-picking device for glass fiber consists of two symmetrically distributed yarn-picking frames. Each yarn-picking frame includes a movable yarn frame base 1, a yarn frame crossbeam 2, a yarn frame frame 3, tiles 4, a vertical cylinder 5, a horizontal cylinder 6, a vertical slide rail 7, a horizontal slide rail 8, an electric cylinder 9, and a distance sensor 10. The horizontal slide rail 8 is fixedly installed on both sides of the movable yarn frame base 1. The two ends of the yarn frame crossbeam 2 are connected to the horizontal slide rail 8 via sliders. The horizontal cylinder 6 is installed on the movable yarn frame. At the middle position on the outer side of the base 1, the telescopic rod of the horizontal cylinder 6 is fixedly connected to the yarn frame beam 2. The vertical cylinder 5 is installed on the yarn frame beam 2, and the telescopic rod of the vertical cylinder 5 is connected to the yarn frame 3. The vertical slide rail 7 is fixedly installed on both sides of the yarn frame 3. The sliders on both sides of the yarn frame beam 2 are installed in cooperation with the vertical slide rail 7. Multiple electric cylinders 9 are fixedly installed on the yarn frame 3. Each electric cylinder 9 is fixedly connected to a tile 4 through a mounting bracket 11. A distance measuring sensor 10 is fixedly installed on each mounting bracket 11.

[0034] Furthermore, such as Figure 4 As shown, each movable yarn frame base 1 has 12 tiles 4, which are installed in four layers, with 3 tiles in each layer. The number and installation position of the tiles 4 can be adjusted according to actual production needs.

[0035] Furthermore, three vertical cylinders 5 are installed on the yarn frame beam 2. The three vertical cylinders 5 are installed at equal intervals. By setting three vertical cylinders 5, the stability of the yarn frame 3 can be improved, while reducing the load on each vertical cylinder 5.

[0036] Furthermore, the controller is a PLC; at the same time, the ranging sensor 10 is an industrial camera. By utilizing the vision technology of the industrial camera, the PLC controls the servo cylinder to make fine adjustments, thereby avoiding the occurrence of yarn clumps not being removed and reducing the intensity of manual labor.

[0037] Furthermore, four foot pads are installed at the four corners of the bottom of the movable yarn frame base 1. The foot pads are threadedly connected to the movable yarn frame base 1. The stability of the movable yarn frame base 1 can be adjusted by the foot pads to prevent the device from shaking due to uneven ground.

[0038] Furthermore, the outer side of the movable yarn frame base 1 is provided with an L-shaped mounting plate 12 for installing the horizontal cylinder 6, which facilitates the installation of the horizontal cylinder 6.

[0039] Furthermore, both the vertical slide rail 7 and the horizontal slide rail 8 are provided with through mounting holes, and bolts pass through the mounting holes to fix the vertical slide rail 7 and the horizontal slide rail 8 onto the yarn frame 3 and the movable yarn frame base 1, respectively.

[0040] Furthermore, the vertical cylinder 5 is a double-stroke cylinder, and the horizontal cylinder 6 is a single-stroke cylinder.

[0041] Furthermore, the tile 4 is made of stainless steel.

[0042] Working Principle: This utility model utilizes the sequential action of vertical, horizontal, and electric cylinders controlled by a PLC. Data communication between the PLCs of the two yarn-picking frames facilitates information exchange. Through human-machine interaction between the PLC and a touchscreen, the system automatically adjusts the yarn trolley based on the size of the yarn trolley, thus solving the problem of yarn clumps falling to the ground and affecting product quality during the picking process. Simultaneously, using industrial camera vision technology, the PLC further controls the servo electric cylinders for fine-tuning, preventing yarn clumps from failing to be picked up. This reduces manual labor intensity, eliminates the need for manual handling, and provides fully automated control of the entire process, improving work efficiency.
