Description

Technical Field

[0001] The invention relates to the technical field of glass fiber production, in particular to an automatic pushing device for offset yarn balls. Background Art

[0002] In the large-scale production of glass fiber, a large number of logistics yarn carts are required. In the automatic circulation process, the yarn carts are prone to deviate from the original position of the yarn balls due to turning, lifting, and passing through the joints of the logistics line, and gradually form the problem of detachment from the cart. The defect of this problem is that the deviation of the yarn balls from the original position will cause the yarn cart to continue to run and cannot pass through the narrow tunnel oven opening, the coding identification door frame and enter the stereoscopic warehouse. If the deviation exceeds the center of gravity of the yarn ball, it will be separated from the yarn car and fall, causing malfunctions in the conveyor line. The yarn balls will also be deformed and contaminated due to falling, resulting in the scrapping of the yarn balls. Therefore, how to provide an automatic detection and automatic pushing device for offset yarn balls that can effectively correct the position deviation of the yarn balls on the yarn cart has become an urgent problem to be solved. Summary of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide an automatic yarn ball pushing device which can automatically detect and push the yarn ball and effectively correct the position deviation of the yarn ball on the yarn carriage.

The linear guide rail is installed on the ball guide rail seat. The connecting plate is an L-shaped connecting plate composed of two plates, one of which is fixedly connected to the linear guide rail, and the other is fixedly connected to the push plate located on the inner side of the gantry assembly through bracket C. The cylinder is installed on the outside of the gantry assembly, and the front end of the piston rod of the cylinder is connected to the connecting plate.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0019] like Figure 1-4As shown, an automatic pushing device for offset yarn balls includes a through-shooting sensor, a push plate 2, a guide rail seat mounting plate 3, a ball guide rail seat 4, a linear guide 5, a connecting plate 6, a cylinder 7, a gantry assembly 9 and a logistics conveying line 13. The through-shooting sensor includes a transmitting end 1 and a receiving end 11, which are respectively fixed to the top and the bottom of the gantry assembly 9 by bracket A and bracket B. The guide rail seat mounting plate 3 is fixed to the outside of the gantry assembly 9 by screws, the ball guide rail seat 4 is connected to the guide rail seat mounting plate 3 by screws, the linear guide 5 is installed on the ball guide rail seat 4, the connecting plate 6 is an L-shaped connecting plate composed of two plates, one of which is fixedly connected to the linear guide 5, and the other plate is connected to the push plate 2 located on the inner side of the gantry assembly 9 by screws through the bracket C, the cylinder 7 is installed on the outside of the gantry assembly 9, and the front end of the piston rod of the cylinder 7 is connected to the connecting plate 6.

[0020] The device also includes a PLC controller (not shown in the figure), and the receiving end 11 of the shooting sensor and the solenoid valve of the cylinder 7 are electrically connected to the PLC controller respectively, so that the present invention can automatically detect in real time and automatically push in when the offset reaches the push-in value.

[0021] A flexible adhesive layer is provided on the side of the push plate 2 opposite to the yarn ball, so as to avoid damage to the yarn when the yarn ball is pushed in.

[0022] The front end of the piston rod of the cylinder 7 is connected to the position fine-tuning screw 10, and the position fine-tuning screw 10 is connected to the connecting plate 6. The position fine-tuning screw 10 can adjust the original position of the push plate.

[0023] The working process of the present invention is as follows: a yarn cart 12 carrying a yarn ball runs in a logistics conveying line 13. When passing through a gantry assembly 9, a transmitting end 1 of a through-beam sensor transmits a signal to detect the position state of the yarn ball offset from the center line of the yarn cart 12. When the yarn ball offsets the yarn cart 12, the offset yarn ball 8 at the center of the yarn cart blocks the signal emitted by the transmitting end 1 of the through-beam sensor, and the receiving end 11 of the through-beam sensor cannot receive the signal emitted by the transmitting end 1 of the through-beam sensor. At this time, the PLC controller controls the solenoid valve of the cylinder 7, so that the piston rod of the cylinder 7 moves toward the direction of the yarn cart 12, so that the push plate 2 moves toward the center of the yarn cart 12 under the guidance of the linear guide rail 5 and the ball guide rail 4, thereby returning the offset yarn ball 8 at the center of the yarn cart to the correct position.
