As shown in fig. 1 and 2, a thread end grasping mechanism 700 is disposed beside a gap between the driving shaft 100 and the driven shaft 200, and the thread end grasping mechanism 700 is used for grasping a thread end of a full thread reel and is matched with the driving shaft, the driven shaft and the automatic clamping jaw 600 to tie a knot. The thread end gripping mechanism 700 comprises a thread end grasper 710, the thread end grasper 710 being connected to a translation drive mechanism 720 driving it to reciprocate in a direction parallel to the axis of the main drive shaft 100.

When the cylinder shaft of the cylinder extends out, the distance between the driving shaft 100 and the driven shaft 200 is reduced to be smaller than the width of the reel, so that the driving shaft 100 and the driven shaft are matched to clamp and fix the full-width reel a10 between the driving shaft 100 and the driven shaft, and the driving shaft 100 is at a clamping position.

As shown in fig. 4, the first driving mechanism 400 includes a motor 410, the motor 410 is connected to a speed reducer 420, the speed reducer 420 is fixed to the outer side of the vertical plate 320, a rotating shaft 421 of the speed reducer 420 passes through a through hole 321 of the vertical plate 320, a bearing 430 is disposed in the through hole 321, a transmission shaft 440 located on the inner side of the vertical plate is coaxially connected to the bearing 430, the transmission shaft 440 is coaxially connected to the rotating shaft 421 of the speed reducer 420, and the front end of the transmission shaft is coaxially disposed on the driving shaft 100.

In addition to the requirement that the two chucks 610 of the automatic clamping jaw 600 can effectively prevent the filament wound thereon from falling off during the rotation process, the requirement that the chucks are convenient to withdraw from the thread loop during the subsequent knotting is also met, so in a preferred embodiment, as shown in fig. 6 and 7, the chucks 610 include a clamping portion 611, the clamping portion 611 and a blocking portion 612 are in obtuse-angle engagement, the outer surfaces of the clamping portion 611 and the blocking portion 612 form a V-shaped limiting groove 614, the blocking portion 612 and the mounting portion 613 are in obtuse-angle engagement, and the extending direction of the mounting portion 613 is parallel or nearly parallel to the extending direction of the clamping portion 611.

Further, when the automatic clamping jaw 600 is located right below the driven shaft 200, it is inclined, that is, the axis of the shaft around which the clamping head 610 rotates is not perpendicular to the horizontal plane, so that when a wire loop is obtained by subsequent winding, the wire loop can be expanded as much as possible to block the wire loop through a subsequent blocking pin, and simultaneously, the distance between the two clamping heads 610 can correspond to the wire held by the wire-end grasper 710.

Example 10

The present embodiment discloses an automatic winding system, as shown in fig. 29, which includes structures of conventional winding systems such as a winding machine e/a paying out machine f, and at least one structure of the foregoing embodiments, for example, when the paying out machine and the winding machine are only one set, only a partial structure of a thread end knotting device may be required, or structures such as a thread end knotting device, a loading and unloading robot, and an automatic thread breaking mechanism may be required to be configured. If the paying-off machine and the winding machine are provided with a plurality of sets, the track and the movable trolley are needed besides the thread end knotting device, the feeding and discharging robot and the automatic thread breaking mechanism. Of course, the automatic supply of the backflow concentration of the empty wheel and the full wheel can be realized only by the full wheel backflow line, the empty wheel conveying line and the loading and unloading robot; and the automatic feeding and discharging can be realized by only arranging structures such as an automatic wire breaking mechanism, a movable trolley and the like, or the automatic threading can be realized by only arranging the structures of the automatic threading device, the 6-axis robot and the transfer trolley. The automatic feeding and discharging device has the advantages that the automatic feeding and discharging device is provided with all the structures, so that automation of the whole processes of stacking, automatic feeding and discharging, knotting, labeling, automatic wire replacing, automatic threading and the like can be realized.

When the whole system works, the automatic control is realized through a control system part, and the corresponding control technology is the prior art and is not limited here.

Example 11

When the whole winding system works, the process is as follows:

in the initial state, an idle wire wheel can be manually installed on each winding machine, and the wire head of the silk thread on one side of the pay-off rack is wound on the idle wire wheel for winding. It is of course also possible to mount the idler wheel on each of said winding machines and thread the thread end into the threading hole of the idler wheel by means of the above-mentioned structure on the travelling carriage k.

When the empty wheel on one winding machine is fully wound and the full wheel a10 needs to be discharged and replaced by the empty wheel a20, the following processes are carried out:

and S10, moving the moving trolley k to the side of the corresponding winding machine.

And S20, the moving mechanism b2 is connected with the wire wheel grabbing device b1 and drives the wire wheel grabbing device b1 to hold a full wire wheel a10 on the winding machine, meanwhile, the wire head clamping jaw b3 clamps the wire between the full wire wheel a10 and the pay-off rack e1, and the moving mechanism b2 drives the wire wheel grabbing device and the wire head clamping jaw to translate the held full wire wheel and the clamped wire to the outer side of the winding machine e for a certain distance. Of course, if there is a sufficient distance between the full reel and the pay-off rack, the reel gripping device b1 may not move the full reel after gripping the full reel, but directly extend the fuse and the pneumatic clamping jaw according to the following steps to perform the wire breaking operation.

And S30, the linear module d500 of the automatic wire-breaking mechanism d drives the mounting frame d100 to extend out of the moving trolley k to reach the gap between the upper fusing head and the lower fusing head of the fuse d200 on the moving trolley k, and the gap corresponds to the position of the wire between the wire head clamping jaw b3 and the pay-off frame e1 and is positioned outside the wire section. Then the sliding table cylinder d300 drives the mounting rack d100 to move towards the silk thread direction, the silk thread between the thread end clamping jaw b3 and the pay-off rack e1 is located in a gap between the upper fusing head and the lower fusing head, then the upper fusing head and the lower fusing head are closed to complete fusing, before fusing, the fusing point and the silk thread of the pay-off rack support are clamped by the pneumatic clamping jaw d700 on the outer side, meanwhile, the diameter of the wound silk thread is measured by the silk diameter detector, and the diameter of the wound silk thread is transmitted to the control system.

S40, after the wire head is fused, the feeding and discharging robot can move the full wire wheel to a knotting position to knot the wire head, and the specific knotting process of the wire head is as follows:

s1, initial state, the cylinder shaft of the power source of the axial driving mechanism is retracted, the cylinder shaft of the translation cylinder is retracted, the thread-end grasper 710 is located at the second position, and the driving shaft 100 is kept at the maximum distance from the driven shaft 200.

S2, the moving mechanism b2 drives the reel gripping device b1 to place the full reel gripped by it coaxially between the driving shaft 100 and the driven shaft 200 and at the same time, the thread end gripper b3 places the thread end of the full reel thread (the thread between the full reel and the thread end gripper) between the two grippers 711 of the thread end gripper 710.

And S3, the axial driving structure 300 drives the driving shaft 100 to move towards the driven shaft 200, the driving shaft and the driven shaft are matched to fix the full-length reel, and the clamping jaws of the thread end grasper 700 are closed to clamp the thread end between the two clamping jaws. Subsequently, the reel gripping device b1 releases the full reel and the thread end clamping jaw b3 releases the thread end, and then the reel gripping device b1 can grip the empty reel to position the pin hole.

S4, the translational driving mechanism 720 drives the thread end grasper 710 to move and reset towards the direction of the driving shaft 100 (the first position), and the thread between the translational driving mechanism and the reel inclines towards the middle from the edge, at this time, the thread end grasper 710 does not interfere with the revolution motion of the automatic clamping jaw.

S5, the motor 410 drives the automatic chuck holding open 600 to revolve around the driven shaft 200 and contact the wire between the reel and the wire end gripper from above, and then the automatic chuck holding open continues to rotate until the gap between the two chucks 610 of the automatic chuck is corresponding to the position of the wire between the full reel and the wire end gripper 710, at which time the wire wound around the two chucks 610 forms a loop a 14. And when the automatic clamping jaw rotates and is contacted with the silk thread to stop rotating, the driving shaft and the driven shaft drive the full-thread wheel to synchronously rotate, and the rotation direction of the full-thread wheel is the same as the revolution direction of the automatic clamping jaw.

S6, the translational driving mechanism 720 drives the wire-end grasper 710 to move toward the driven shaft 200 so that the wire between the wire-end grasper and the reel moves to between the two chucks 610 of the automatic clamping jaw 600.

S7, the two jaws 610 are closed to grip the wire between them, and then the two jaws of the wire end grasper 710 are opened to release the gripped wire end.

And S8, the full reel a10 rotates reversely and/or the automatic clamping jaw 600 revolves downwards continuously, so that the clamping head of the automatic clamping jaw 600 is moved out of the wire loop to finish knotting.

And S9, the chuck of the automatic clamping jaw 600 is loosened, and the moving mechanism b2 drives the reel gripping device b1 to place the reel at the full-wheel return line p.

Of course, in a more preferred embodiment, after the step S6 and before the step S8, the blocking pin is extended, so that the wire loop can be prevented from following the action of the automatic clamping jaw 600 by the blocking pin, and the reliability of knotting is ensured, although the process is not necessary and can be omitted.

And before the knotted full-length reel is placed on the full-length-reel return line p, labeling is carried out on the full-length reel by a labeling device h, after the end of the line is knotted, the position of a groove on the end face of the full-length reel is determined by an image collected by an image collecting device i100, and when the position is not suitable for labeling, the driving wheel 100 rotates to drive the full-length reel a10 to rotate to a suitable labeling position and then stops. Then, the moving mechanism b2 drives the reel gripping device b1 to grip and move the reel adjusted in position to the labeling position. Label that this full line wheel of label generation device g on-line generation corresponds and export adsorb piece j100, adsorb piece j100 will the label adsorbs, jacking cylinder j300 drive adsorb piece j100 lifting to deck plate 1100 top, labeling device h's lift slip table cylinder h400, translation slip table cylinder h500 and first straight line module h600, the cooperation of second straight line module h800 drive sucking disc h100 move to with the label on adsorbing piece j100 just adsorbs from the top of label to the separation of glue film and release layer is realized under the effect of upper and lower adsorption to the label of taking the gum is adsorbed on sucking disc h100, revolving cylinder h300 drive the sucking disc is rotatory 90, makes the label of adsorbing on it towards the terminal surface of full line wheel, then lift cylinder h400, translation slip table cylinder h500 and first straight line module h600, And the second linear module h800 is matched with the label to be attached to the end face of the full-line wheel, and after the label is attached, the full-line wheel is placed on the full-line return line p for backflow conveying.

And S50, after the full-line wheel is fed from the winding machine, another empty line wheel needs to be installed on the winding machine, namely the moving mechanism b2 drives the line wheel gripping device b1 to the empty wheel cache groove o3 or the empty wheel conveying line o corresponding to the winding machine to grip an empty line wheel, the empty line wheel is coaxially placed on the servo rotating platform m200, the servo rotating platform m200 drives the empty line wheel to rotate, the pin holes in the wheel disc of the line wheel are determined through the sensor m300, and when the pin holes are opposite to the sensor, the servo rotating platform m200 stops rotating. During the action of pin hole finding, the wire wheel gripping device b1 can move the full wire wheel which is knotted to the labeling position for labeling and blanking, after blanking is completed, the moving mechanism b2 drives the wire wheel gripping device b1 to grip the empty wire wheel with the aligned pin hole on the servo rotating platform m200 and move the empty wire wheel to the winding machine, the position of the positioning pin on the winding machine is determined by the image collector b202 on the moving mechanism b2, then the moving mechanism b2 drives the wire wheel gripping device b1 to move the empty wire wheel which is gripped by the wire wheel gripping device b1 to the state that the empty wire wheel is coaxial with the winding shaft of the winding machine and the pin hole on the wheel disc is coaxial with the winding wire and the positioning pin on the winding wire, and then the winding.

S60, after the aerial wheel is installed, a thread head needs to penetrate into a threading hole in a thread shaft of the aerial wheel, and the method specifically comprises the following steps:

s601, the moving mechanism b2 drives the reel gripping device b1 to move to the placing rack 1200 on the side of the placing platform, and then the moving mechanism b2 is separated from the reel gripping device b1 and moves to the position of the automatic threading device n to be connected with the quick-change disk n110 of the automatic threading device n.

And S602, the winding machine drives the idle wheel to rotate, the image collector b202 on the moving mechanism b2 searches for the threading hole on the idle wheel, and the winding machine stops when the threading hole is upward.

S603, the moving mechanism b2 drives the automatic threading device n to move and move to the automatic thread breaking mechanism d to grab the thread between the pneumatic clamping jaw d700 and the pay-off rack e1 on the outer side, during thread grabbing, the cylinder shaft of the pushing cylinder n400 extends out, the cylinder shaft of the shifting cylinder n900 retracts, and after the thread head is grabbed, the automatic thread breaking mechanism d resets to wait for next thread fusing.

S604, as shown in fig. 26, the moving mechanism b2 drives the automatic threading device n to move to a state where the first threading jaw n200 is below and the second threading jaw n300 is above, and then moves the carrier n100 downward to insert a thread end below the first threading jaw n200 into the threading hole of the aerial wheel after determining the position relationship between the thread end and the threading hole according to the visual positioning.

S605, when the first threading holding jaw n200 approaches the reel axis of the aerial reel a20, the downward movement is stopped, and then the first threading holding jaw n200 is opened and then moved upward and leftward to avoid the threading (i.e., the cylinder axis of the pushing cylinder n400 is retracted and the cylinder axis of the shifting cylinder n900 is extended).

S606, the moving mechanism b2 drives the bearing member n100 to rotate (clockwise), so that the second threading jaw n300 rotates from the inclined state to the vertical or near vertical state, as shown in fig. 27, and thus the second threading jaw n300 inserts the thread at the front end into the threading hole again to complete threading.

And S607, extending out the cylinder shaft of the pressing cylinder n2, so that the press roller n1 presses the silk thread between the second threading clamping jaw n300 and the pay-off rack on the reel shaft of the aerial reel.

And S608, the second threading clamping jaw loosens the thread grabbed by the second threading clamping jaw, the winding shaft of the winding machine e drives the idle wheel to rotate for winding, after the idle wheel is pre-wound for a plurality of circles, the pressing cylinder n2 retracts, and the winding machine continues to wind the thread.

And S609, after threading is completed, the moving mechanism b2 drives the automatic threading device n to move to the frame 1300 at the side part of the placing table 1000, and then the automatic threading device n is separated from the automatic threading device n and is connected with the wire wheel grabbing clamping jaw again.
