Description

Technical Field

[0001] This utility model relates to the technical field of yarn conveying equipment, specifically a yarn hanging frame positioning device. Background Technology

[0002] In the textile industry, yarn humidification is a crucial process for improving yarn quality. Humidification improves the moisture regain of the yarn, reducing yarn breakage during subsequent weaving. The yarn hanger, as the core equipment supporting the yarn in the humidification process, significantly impacts the positioning accuracy of the robotic arms that handle yarn loading and unloading within the humidification chamber. Inaccurate positioning can lead to the robotic arms failing to properly handle the yarn, resulting in yarn damage or equipment failure.

[0003] Currently, most yarn hanging frames used in textile manufacturing enterprises for yarn conveying are passive track pulley type positioning systems. These rely on rollers installed below the yarn hanging frame, which slide along a track for positioning. This positioning method has low accuracy and can only achieve positioning parallel to the guide rail by locking the rollers against the guide rail wall, greatly increasing the difficulty for the yarn-picking robot to pick up the yarn. Utility Model Content

[0004] This utility model proposes a yarn hanger positioning device with a simple structure, high positioning accuracy, and the ability to achieve active positioning.

[0005] A yarn hanging rack positioning device includes a positioning rod, one end of which is fixedly connected to a mounting frame. The mounting frame is provided with a support rod, and the end of the support rod away from the mounting frame is provided with a guide mechanism. The mounting frame is provided with a driving mechanism, and the output end of the driving mechanism is fixedly connected to a joint clamping mechanism for clamping the yarn hanging rack. The joint clamping mechanism abuts against the guide mechanism. The joint clamping mechanism includes a joint base fixedly connected to the output end of the drive mechanism. A movable connecting piece is hinged to one side of the joint base. A clamping assembly is hinged to the movable connecting piece. A stop assembly that abuts against the guide mechanism is hinged to the clamping assembly. The guide mechanism is equipped with a position sensor for detecting the position of the yarn hanging frame. With the above structure, by setting a position sensor and a guide mechanism, the position of the yarn hanging frame can be detected to confirm whether the yarn hanging frame is in place. By setting a joint clamping mechanism and a drive mechanism, the drive mechanism drives the joint clamping mechanism to clamp the yarn hanging frame and fix the yarn hanging frame to facilitate subsequent operations of picking up and putting down yarn packages.

[0006] In order to enable the joint clamping mechanism and the guide mechanism to cooperate better, the stop assembly includes a hinge frame, both ends of which are hinged to the clamping assembly. Stop plates are provided on both sides of the hinge frame, and the stop plates abut against the guide mechanism. Preferably, the guiding mechanism includes a guide plate, the guide plate having a fixing part that abuts against the stop plate, and the fixing part being fixedly connected to the support rod. In order for the joint clamping mechanism to better clamp the yarn hanger, the clamping assembly includes a clamping plate, one end of which is hinged to the hinge frame, and the other end of the clamping plate is fixedly connected to a pulling part, the end of which is away from the clamping plate is hinged to the movable connecting piece.

[0007] To facilitate the adjustment of the position of the guide mechanism, the support rod is a threaded rod, which is equipped with a mounting bracket fixing nut and a guide mechanism fixing nut. The support rod is fixedly connected to the mounting bracket by the mounting bracket fixing nut, and the support rod is fixedly connected to the guide mechanism by the guide mechanism fixing nut.

[0008] Preferably, the mounting bracket includes a horizontal mounting piece fixedly connected to the positioning rod, a vertical mounting piece is provided on one side of the horizontal mounting piece, the horizontal mounting piece is fixedly connected to the support rod, and the vertical mounting piece is fixedly connected to the drive mechanism.

[0009] Preferably, the driving mechanism is a push rod cylinder, and the position sensor is a photoelectric sensor.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are: The yarn hanging rack positioning device provided by this utility model is equipped with a position sensor and a guide mechanism. The yarn hanging rack moves along the guide mechanism, and the position sensor can actively detect the position of the yarn hanging rack to confirm whether the yarn hanging rack is in place. The whole device has a simple structure, high positioning accuracy and can achieve active positioning. It is equipped with a joint clamping mechanism and a drive mechanism. The drive mechanism drives the joint clamping mechanism to clamp the yarn hanging rack and fix the yarn hanging rack so as to facilitate the operation of the robotic arm for picking up and putting down yarn in the yarn humidification warehouse.

Each fixing part is fixedly connected to two support rods. The support rods pass through the transverse mounting plate and slide with the transverse mounting plate.

[0021] The clamping assembly 34 includes a clamping plate. One end of the clamping plate is hinged to the hinge frame 351, and the other end of the clamping plate is fixedly connected to a pulling part. The end of the pulling part away from the clamping plate is hinged to the movable connecting piece 33. The clamping assembly 34 is provided in two sets.
