Description

Technical Field

[0001] The present application belongs to the technical field of glass fiber production, and specifically relates to an automatic yarn breaking mechanism of a yarn unloading robot. Background Art

[0002] In the process of glass fiber drawing, the high labor intensity and harsh environment of drawing work have caused a labor shortage. Although some large enterprises have used yarn unloading mechanisms to remove full-bore yarn balls from drawing machines and put them into the yarn cart to reduce some workload, the current use of yarn unloading mechanisms for the removal of direct yarn cylindrical yarn balls is still limited to a maximum of three yarn balls at a time. If there are more than three yarn balls, the drawing machine's barrel pushing mechanism needs to assist in taking them out in multiple times. During the yarn unloading process, the inner and outer layers of the connecting yarns between the yarn balls must also be manually cut and separated before the yarn unloading mechanism can remove the yarn balls and put them into the yarn cart. Such yarn unloading mechanisms are complex in structure and large in size due to the large size of the telescopic mechanism, the inlet and outlet ports are in the same direction, and the rotation space is also large. They are not suitable for the yarn unloading work of four-point drawing and five-point drawing, and there are also safety hazards in human-machine cooperation. In order to save energy, reduce emissions and improve efficiency, the wire drawing technology of the wire drawing machine with the large leak plate process has been developed, from four-point drawing, five-point drawing, to six-point drawing and even four-head four-point drawing and five-point drawing. However, the yarn unloading mechanism is directly affected by the factory space and cannot be extended, let alone rotated. This has caused a problem in the use of the yarn unloading mechanism equipment. In order to solve the problems of improving production efficiency and automation level of existing factories and safety hazards, a yarn cutting mechanism that can automatically cut the inner and outer layers of the connecting yarn between the yarn balls has become a top priority.

[0036] Application environment description: The automatic yarn breaking mechanism of the yarn unloading robot disclosed in this application is applied to the drawing production of glass fiber. When the glass fiber is drawn into a wire and wound into a yarn ball by a drawing machine, one or more yarn balls will be formed on the head of the drawing machine. The four-point drawing will form four yarn balls on the head shaft side by side on one head (such as Figure 2 As shown). After the yarn balls are wound and formed, they need to be removed from the head shaft of the wire drawing machine and placed on the yarn cart, and then the yarn cart transports the yarn balls to the next process. Among them: there is a yarn ball connection between each two adjacent yarn balls in the multiple yarn balls. When placing the yarn (the process of placing the yarn balls on the yarn cart), these yarn ball connection lines need to be cut off to facilitate subsequent weighing, placement, transportation and other processes. The automatic yarn cutting mechanism of the yarn unloading robot disclosed in this application is a special equipment for automatically cutting the connection between yarn balls.

[0037] See also Figure 1-Figure 4The automatic yarn breaking mechanism of the yarn manipulator provided in the present application includes a rack knife pad 10, a rack knife holder 20, a yarn breaking blade 30, a yarn breaking gear 40, a yarn breaking actuator 50, a yarn breaking knife pad 60, and a mounting frame 70.

[0038] The rack shim 10 includes a shim rack portion 110 and a shim portion 120; the rack tool holder 20 includes a tool holder rack portion 210 and a tool holder portion 220. The extension direction of the shim rack portion 110 and the extension direction of the shim portion 120 are perpendicular to each other; the extension direction of the tool holder rack portion 210 and the extension direction of the tool holder portion 220 are perpendicular to each other.

[0039] The yarn breaking gear 40, the yarn breaking actuator 50, the knife pad rack portion 110, and the knife holder rack portion 210 are all arranged on the mounting frame 70. The yarn breaking actuator 50 outputs power to the yarn breaking gear 40. The knife pad rack portion 110 and the knife holder rack portion 210 are respectively engaged with the two sides of the yarn breaking gear 40. The yarn breaking blade 30 is arranged on the knife holder portion 220 of the rack knife holder 20, and the knife pad 60 is arranged on the knife pad portion 120 of the rack knife pad 10.

[0040] When the yarn breaking actuator 50 is running, it can drive the yarn breaking gear 40 to rotate clockwise or counterclockwise; when the yarn breaking gear 40 rotates, it can make the knife pad part 120 and the knife holder part 220 close together to cut off the yarn between the yarn balls through the transmission between the gear racks, and it can also make the knife pad part 120 and the knife holder part 220 automatically separate to continue to put in the yarn ball connection that needs to be cut.

[0041] The yarn-breaking actuator 50 may be an oil cylinder, an air cylinder or a motor. The oil cylinder may be a rotary air cylinder, the oil cylinder may be a rotary oil cylinder, and the motor may be a driving motor. As long as the yarn-breaking gear 40 can be driven to rotate clockwise and counterclockwise, the technical solution of the present application can be realized.

[0042] In some embodiments of the present application, in order to enhance the stability of the rack knife pad 10 and the rack knife holder 20 when closing or separating, a guide rail or guide groove for the knife pad rack part 110 and the knife holder rack part 210 to make straight reciprocating motion can also be provided on the mounting frame 70, and the knife pad rack part 110 and the knife holder rack part 210 are respectively snapped or nested in the guide rail or guide groove, which can increase the stability of the motion on the one hand, and reduce the motion resistance of the knife pad rack part and the knife holder rack part on the other hand. The structure, function and connection method of the guide rail and the guide groove are common technical knowledge in the field and will not be described in detail here.

[0043] The yarn breaking process corresponding to the automatic yarn breaking mechanism of the yarn unloading robot includes the following working states:

[0044] In the standby state, the knife pad part and the knife holder part of the automatic yarn cutting mechanism are in a separated state, waiting for the yarn group connection line that needs to be cut to enter between the knife pad part and the knife holder part. Figure 4 As shown;

[0045] In the yarn breaking state, after the connecting line between the yarn balls that need to be cut enters between the knife pad part and the knife holder part, the yarn breaking actuator drives the yarn breaking gear to rotate so that the knife pad part and the knife holder part are closed, and the connecting line between the yarn balls is cut off. Figure 3 As shown;

[0046] In the recovery state, after the connection between the yarn balls is cut off, the yarn breaking actuator drives the yarn breaking gear to rotate so that the rack knife pad and the rack knife holder move to both sides respectively, and the knife pad part and the knife holder part return to the separated state, that is, the standby state.

[0047] In summary, the automatic yarn cutting mechanism of the yarn unloading robot provided in the present application can automatically cut off the connection between the yarn ball placed between the knife pad part 120 and the knife holder part 220 by command control of the yarn breaking actuator 50, which is beneficial to improve the degree of automation of the production line, reduce the labor intensity of workers, and improve the production efficiency and safety conditions of the workshop.
