Description

Technical Field

[0001] The present invention relates to the field of automatic production, and particularly relates to an automatic yarn ball turning machine and a method for yarn ball turning operation. Background Art

[0002] In the production of glass fibers, it is necessary to turn the yarn balls unloaded by mechanical grippers. In the past, this was done manually, which formed a significant contrast with the numerical control and intelligent work of robots. Moreover, each employee needed to turn more than 40 tons per shift, with a relatively high labor intensity, and this work required male employees with greater strength to complete. The purpose of the present invention is to use a machine to achieve automatic turning of yarn balls, so that the working process of this position matches the automatic and intelligent work of robots, greatly reducing the labor intensity of employees and improving work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an automatic yarn ball turning machine and an operation method that can reduce the labor intensity of employees and improve production efficiency.

[0004] The purpose of the present invention is achieved through the following technical solutions: An automatic yarn ball turning machine includes a mechanical gripper for unloading yarn balls during the production process and a conveyor line for conveying the turned yarn balls, and further includes a frame, a clamping mechanism, and a rotational power mechanism installed on the frame; wherein:

[0005] The clamping mechanism is directly below the end point of the stroke of the mechanical gripper; the frame is fixed at the starting end of the conveyor line; the clamping mechanism is movably connected to the frame; the rotational power mechanism is fixedly connected to the clamping mechanism.

[0006] Preferably, the clamping mechanism includes a fixed clamping component, a yarn ball receiving plate, a movable clamping component, and a telescopic mechanism. The fixed clamping component is fixed at one end of the yarn ball receiving plate; a linear guide rail is provided on the yarn ball receiving plate at the other end, and the movable clamping component is movably connected to the linear guide rail; the telescopic mechanism is fixed under the yarn ball receiving plate. The telescopic mechanism includes a cylinder and a telescopic rod. One end of the telescopic rod is placed inside the cylinder and is movably connected to the cylinder, and the other end of the telescopic rod is fixedly connected to the movable clamping component.

[0007] Preferably, the rotational power mechanism includes a rotational motor, a speed reducer, and a driven wheel. The rotational motor and the speed reducer are movably connected through a conventional worm and worm gear transmission mechanism; the speed reducer is fixed on the frame, a driving wheel is provided on the output shaft of the speed reducer, and a chain for transmission is provided between the driving wheel and the driven wheel; the driven wheel is fixedly connected to the fixed clamping component.

[0008] Preferably, a support rod is provided on the frame, a rotating shaft is provided on the support rod, and the installation height of the rotating shaft is the same as the height of the rotation center of the yarn bobbin; the centers of the driven wheel and the fixed clamping assembly are both movably connected to the rotating shaft through bearings.

[0009] Preferably, it further includes a control system, and the rotating motor, the mechanical gripper and the telescopic mechanism are all connected to the control system.

[0010] Preferably, an opening switch is provided at the starting end of the conveyor line.

[0011] A method for the yarn bobbin flipping operation of a yarn bobbin automatic flipping machine includes the following steps:

[0012] S1: The yarn bobbin to be flipped is grabbed by the mechanical gripper from the production line and placed on the yarn bobbin receiving plate. The mechanical gripper resets, and the control system controls the cylinder in the telescopic mechanism to be inflated, so that the telescopic rod drives the moving clamping assembly to move close to the yarn bobbin and clamp the yarn bobbin to be flipped;

[0013] S2: The control system controls the rotating motor. After being decelerated by the speed reducer, the torque output by the rotating motor is output from the driving wheel installed on the speed reducer, and the torque is transmitted to the driven wheel through the chain drive;

[0014] S3: The driven wheel is fixedly connected to the fixed clamping assembly, that is, the driven wheel can drive the clamping mechanism to rotate 180° around the rotating shaft, so as to complete the 180° flipping of the yarn bobbin onto the conveyor line;

[0015] S4: After the yarn bobbin flipping is completed, the control system controls the telescopic mechanism, so that the telescopic rod drives the moving clamping assembly to move away from the yarn bobbin, thereby releasing the yarn bobbin;

[0016] S5: The control system controls the rotating motor to reverse, and after the above S2 step, the clamping mechanism is reset, waiting for the subsequent yarn bobbin flipping work; during the reset movement of the clamping mechanism, the lower part of the fixed clamping assembly will push the yarn bobbin to move a short distance in the movement direction of the conveyor line, triggering the opening switch of the conveyor line, so that the conveyor line works to convey the flipped yarn bobbin to the next process.

[0017] The present invention has the following advantages:

[0018] 1. The speed reducer has a self-locking function, which can effectively prevent the unstable operation state of the device caused by the change of the center of gravity during the yarn bobbin flipping process;
