Next, a wire feeding start/stop control method of a multi-axis horizontal swing rod type automatic wire feeding frame is introduced, when a wire is pulled to be tensioned, the wire drives the swing rod 32 to swing upwards, so that the first metal conduction part 312 on the swing rod 32 is separated from the second metal conduction part 313, and the paying-off shaft 10 starts to rotate for paying off; when the wire is not pulled, the swinging rod 32 stops at the first metal conduction part 312 under the action of its own weight, so that the second metal conduction part 313 contacts with the first metal conduction part 312 to form conduction, and the paying-off shaft 10 stops rotating and paying off. Normally, the paying-off shaft 10 is driven by the motor 20 to rotate and pay off, the first metal conduction part 312 and the second metal conduction part 313 are respectively connected to the control unit 40, and the control unit 40 controls the motor 20 to stop and start according to the connection and disconnection of the first metal conduction part 312 and the second metal conduction part 313.
Next, the following operation procedure of the multi-axis horizontal swing link type automatic wire feeding rack of the present embodiment is generally described:
first, as shown in fig. 5, the wire 70 is in a relaxed state (also referred to as an untensioned state/untensioned state), the swinging rod 32 moves downward due to its own weight and rests on the first metal conduction part 312, so that the second metal conduction part 313 contacts with the first metal conduction part 312 to form conduction, the control unit 40 controls the motor 20 to stop according to the conduction signals of the first metal conduction part 312 and the second metal conduction part 313, and the paying-off shaft 10 is in a rotation-stopped paying-off state;
as shown in fig. 8, when the wire 70 is pulled and tensioned, the wire 70 drives the swinging rod 32 to swing upwards, so that the first metal conduction part 312 on the swinging rod 32 is separated from the second metal conduction part 313, and the paying-off shaft 10 starts to rotate and pay off; the control unit 40 controls the motor 20 to start according to the turn-off signals of the first metal conduction part 312 and the second metal conduction part 313, and continuously pay until the wire is in a relaxed state, the swinging rod 32 moves downwards due to self weight, stops on the first metal conduction part 312, and makes the second metal conduction part 313 contact with the first metal conduction part 312 to form conduction, the control unit 40 controls the motor 20 to stop according to the turn-on signals of the first metal conduction part 312 and the second metal conduction part 313, and the pay-off shaft 10 is in a rotation stop pay-off state.
Therefore, the real-time performance of the wire feeding start-stop control of the multi-shaft horizontal swing rod type automatic wire feeding frame is good, when the wire is pulled, the wire can be pulled and tensioned for a short time, and the motor 20 starts the wire feeding to ensure that the wire is continuously pulled and conveyed in a tensioned state; similarly, when the wire drawing is stopped at the wire drawing side (also referred to as the wire processing side), a short time is required to make the wire in the loosening state so that the swinging rod 32 moves downwards due to the self-weight and stops on the first metal conduction part 312 to be contacted and conducted, the motor 20 is correspondingly controlled to stop, and the paying-off shaft 10 is in the rotation stopping paying-off state, so that the wire drawing stock before the next wire drawing and tensioning is reserved, and the phenomenon of forced wire drawing is avoided.
In another embodiment, an elastic restoring member for providing an elastic restoring force for restoring the front end of the swing lever 32 downward is further provided. Thus, when the wire 70 is pulled and tensioned, the wire 70 exerts an upward force on the cycloid wheel 33 (when the upward force is sufficient to overcome the elastic return force), and the swinging rod 32 is further driven to swing upward. When the wire 70 is in a relaxed state and there is no upward force of the wire 70 on the cycloid wheel 33, the front end of the oscillating lever 32 is swung downward to be reset under the elastic reset force of the elastic reset member. Usually, a torsion spring is installed at the position corresponding to the hinge position 311, and the torsion spring includes a spring body and two torsion arms connected to two ends of the spring body, one torsion arm acts on the swing base frame 31, and the other torsion arm acts on the front side of the swing lever 32 located at the hinge position 311.
The signal feedback of the approaching and separating state between the swing lever 32 and the first trigger is not limited to the design of the first and second metal vias 312 and 313; the first trigger part can also be designed as a first inductor; the swing lever 32 is close to the first sensor downwards and far away from the first sensor upwards, so that the first sensor feeds back two different signals to the control unit 40, and the control unit 40 correspondingly controls the motor 20 to stop and start according to the two different signals fed back by the first sensor.
Or, a second sensor may be disposed on the oscillating rod 32 corresponding to the first triggering portion, and the second sensor of the oscillating rod 32 is close to the first triggering portion downwards and far away from the first triggering portion upwards, so that the second sensor feeds back two different signals toward the control unit 40, and the control unit 40 correspondingly controls the motor 20 to stop and start according to the two different signals fed back by the second sensor.
The first sensor and the second sensor can adopt a proximity sensor, a touch sensor, a photoelectric sensor (preferably a shading type photoelectric sensor) and the like.
The invention is characterized in that the swing rod stops at the first trigger part through the structural design of the swing component and the loose wire state, and the control unit controls the motor to stop according to the conducting signal; in a wire pulling state, the swinging rod swings upwards around the hinge joint position, the swinging rod is separated from the first triggering part upwards, and the control unit controls the motor to start paying off according to the disconnection signal; the control unit correspondingly controls the motor to stop and start according to the approaching and the departing of the swinging rod and the first triggering part, and the problem of the existing forced wire pulling can be effectively solved.
And, through setting up swing assembly's articulated position and paying out shaft parallel, when the multiaxis was used, the threading was simpler, was convenient for change the spool, and the bending angle was great when sending the line, and the number of times of bending is less, and is more level and smooth, is applicable to the product that has a higher requirement for wire rod quality, and moreover, the cost is lower, and the installation is simpler, and it can solve current wire feeding frame effectively and change the spool inconveniently, and the bending angle is less when sending the line, and the wire rod trend is smooth inadequately, is not suitable for the problem of the automatic wire feeding of the product that has a higher requirement for wire rod quality.
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
