Referring to fig. 1, 2 and 3, an embodiment of the present invention relates to a bobbin position detecting device 10 mounted on a bobbin winder 700. The bobbin position detecting device 10 includes a housing 100, a yarn monitoring mechanism 200, a swinging mechanism 300, a stopping mechanism 400, a bobbin winding base 500, and a circulating mechanism 600. The yarn monitoring mechanism 200, the swing mechanism 300, the stopper mechanism 400, the winding base 500, and the circulation mechanism 600 are disposed inside the housing 100. The yarn monitoring mechanism 200 is used for detecting whether the yarn 900 exists or not, and the yarn monitoring mechanism 200 is synchronously linked with the swinging mechanism 300. The swing mechanism 300 is movably connected with the stop mechanism 400. The stopping mechanism 400 is hinged to the spooling base 500. The swing mechanism 300 is used to drive the swing mechanism 300 to reset.

Referring to fig. 3, the winder 700 includes a bobbin 710 to be wound, a tension adjusting mechanism 720, a bobbin 730, and a driving sheave 740. The tension adjusting mechanism 720 is used for adjusting the tension of the yarn 900. Before winding, the operator pulls out the yarn 900 on the yarn 710 to be wound, passes through the tension adjusting mechanism 720 and the bobbin position detecting device 10 in sequence, and then winds the yarn 900 onto the bobbin 730.

Referring to fig. 1 and 4, the yarn monitoring mechanism 200 includes a pendulum 210, a thread pressing bar 220, a thread pressing bar limiting assembly 230, and a counterweight adjustment block 240. The thread pressing lever 220 is used for monitoring whether the yarn 900 exists or not, and the thread pressing lever 220 can swing between an initial position and a working position. The presser bar 220 is movable from an initial position to a working position under the action of the yarn 900 when the yarn 900 is detected. The wire pressing rod limiting assembly 230 is used for limiting the swing range of the wire pressing rod 220. The wire pressing rod 220 is fixedly connected with the pendulum 210, so that the pendulum 210 and the wire pressing rod 220 are synchronously linked. The weight adjusting block 240 is adjustably mounted to the pendulum 210 for adjusting the weight of the pendulum 210.

Referring to fig. 4, the pressing bar limiting assembly 230 includes an elastic plate 231 fixedly connected to the pendulum 210, a limiting plate 232 slidably connected to the inside of the housing 100, a limiting member 233, and two limiting members 234. The two limit blocks 234 are respectively disposed on the first side and the second side of the limit block 232, and the two limit blocks 234 are disposed in a staggered manner and clamp one end of the elastic piece 231 between the two limit blocks 234. The limiting member 233 is used to limit the movement range of the limiting plate 232.

When the yarn 900 is detected by the yarn pressing rod 220, as shown in fig. 1, the yarn 900 lifts the yarn pressing rod 220, and at this time, the yarn pressing rod 220 is in the working position, so that the yarn pressing rod 220 rotates clockwise, and the pendulum 210 and the elastic piece 231 are synchronously driven to rotate clockwise. Because the elastic piece 231 is always clamped between the two stoppers 234. When the elastic piece 231 rotates clockwise, the limiting plate 232 can be driven to move downwards. When the thread pressing rod 220 detects that there is no yarn 900, as shown in fig. 2, at this time, the thread pressing rod 220 is at the initial position, the thread pressing rod 220 rotates counterclockwise back to the initial position, and the pendulum 210 and the elastic piece 231 are synchronously driven to rotate counterclockwise. When the elastic piece 231 rotates counterclockwise, the limiting plate 232 can be driven to move upward. The limiting member 233 limits the movement of the limiting plate 232, so that the limiting plate 232 moves within a certain range.

The limiting member 233 includes a first sliding groove disposed at a first end of the limiting plate 232, a second sliding groove disposed at a second end of the limiting plate 232, a first mounting hole and a second mounting hole disposed on the housing 100, and a first limiting nail and a second limiting nail. The first limiting nail penetrates through the first sliding groove and is matched with the first mounting hole, and the second limiting nail penetrates through the second sliding groove and is matched with the second mounting hole. The first limiting nail is fixedly arranged in the first mounting hole, and the second limiting nail is fixedly arranged in the second mounting hole. The first sliding groove is connected with the first limiting nail in a sliding mode, and the second sliding groove is connected with the second limiting nail in a sliding mode.

It should be understood that the moving length of the limiting plate 232 depends on the shorter length of the first sliding groove and the second sliding groove. For example: the length of the first sliding groove is greater than that of the second sliding groove, and the moving length of the limit plate 232 depends on the length of the second sliding groove. In this embodiment, the second sliding groove has a lower end opening, and the tank bottom of second sliding groove can be in butt joint with the second stop pin. The first sliding groove and the second sliding groove have the same length. In other embodiments, the second sliding groove and the first sliding groove are the same in shape and size.

The counterweight adjusting block 240 is formed with an adjusting groove 241 as shown in fig. 5. The pendulum 210 is provided with a threaded hole. The adjusting bolt is inserted into the adjusting groove 241 and is connected with the thread hole in a threaded manner. When adjustment is required, the adjustment bolt is loosened and the adjustment groove 241 of the weight adjustment block 240 is adjusted. When the adjusting groove 241 is adjusted to meet the weight requirement, the adjusting bolt is tightened to fix the counterweight adjusting block 240. It should be understood that the adjustment slot 241 has an arc, and the pendulum 210 is subject to different gravitational forces corresponding to different positions of the adjustment slot 241.

Referring to fig. 1 and 2, the swing mechanism 300 includes a first swing link 310 and a second swing link 320.

When the thread press bar 220 detects the absence of the yarn 900, as shown in fig. 2, the pendulum 210 and the swing mechanism 300 are both in the initial position. When the thread take-up lever 220 detects the presence of the thread 900, the pendulum 210 rotates clockwise as shown in fig. 1. When the pendulum 210 rotates clockwise, the swing mechanism 300 is synchronously driven to rotate clockwise.

Referring to fig. 1 and 6, the bobbin spindle position detecting device 10 further includes a control module 800, a swing link detecting mechanism 810 for detecting whether the first swing link 310 of the swing mechanism 300 normally operates, an alarm mechanism 820, and a human-machine interface 830. The control module 800 is communicatively coupled to the pendulum detection mechanism 810 and to the control alarm mechanism 820. Human-machine interface 830 is communicatively coupled to control module 800. The alarm mechanism 820 includes a buzzer and a flashlight. The control module 800 is used for realizing automatic control, and for example, a PLC may be adopted, and an MCS-51 single chip microcomputer may also be adopted. The human-computer interface 830 can construct a dynamic picture according to the data transmitted by the control module 800, display the operation state of the winding spindle position in real time, make a production efficiency report, a product report and the like, and can improve the field management level.

It should be understood that the first swing link 310 has an initial position and a working position. When the first swing link 310 is at the initial position as shown in fig. 2, the first swing link 310 belongs to an abnormal operation state. When the first swing link 310 is in the working position as shown in fig. 1, the first swing link 310 belongs to a normal operation state. The first swing link 310 moves a predetermined distance in the working position relative to the working position. In this embodiment, the swing link detecting mechanism 810 is disposed at the first swing link 310, and the swing link detecting mechanism 810 adopts a micro switch. The micro switch comprises a spring piece, a roller and a metal contact. When the first swing link 310 is at the initial position, the first swing link 310 contacts with the spring plate and the roller of the micro switch, and the metal contact is disconnected. When the first swing link 310 is at the working position, the first swing link 310 is separated from the spring plate and the roller of the micro switch, and the metal contact is connected. In other embodiments, the swing link detecting mechanism 810 may be an infrared sensor, an ultrasonic sensor, a travel switch, etc., as long as the function of detecting whether the first swing link 310 operates normally can be achieved.

Referring to fig. 1 and 2, the detent mechanism 400 includes a detent lever 410, a detent lever power assembly. The stopping rod power assembly is used for driving the stopping rod 400 to move up and down, so that when the wire pressing rod is in the working position, the first end of the stopping rod 400 can be fixed relative to the second end of the second swing rod 320 through the self-locking structure.

The first end of the stopping rod 410 is fixedly connected with the second end of the second swing link 320 through a self-locking structure.

The self-locking structure includes a plurality of inclined latch teeth disposed on the stopping rod 410 and disposed at equal intervals along the length direction of the stopping rod 410, and a stopping block 340 formed at the first end of the second swing link 320 and abutting against the inclined latch teeth to form an inclined surface fit. A groove portion is formed at the second end of the second swing link 320, and the bottom of the groove portion is an inclined surface matched with the shape of the inclined latch. The bottom of the groove portion extends outward to form a stop 340.

Referring to fig. 1 and 2, the stopping lever power assembly includes an operating handle 420, a connecting cam. The connecting cam is hinged to the housing 100 through the second central shaft 430, and the connecting cam is fixedly connected to the second central shaft 430. One end of the second central shaft 430 extends to the outside of the housing 100, and the operating handle 420 is fixedly connected to one end of the second central shaft 430 extending to the outside of the housing 100. The connecting cam is provided with a projection which can abut against the stop lever 410. The operating handle 420 is used for driving the second central shaft 430 to rotate clockwise, and makes the connecting cam and the protrusion of the connecting cam rotate clockwise synchronously, so as to drive the stopping rod 410 to rotate clockwise.

Referring to fig. 1 and 3, the bobbin winding base 500 is hinged to the second end of the stopping rod 410 and is synchronously linked with the second end of the stopping rod 410. The bobbin winding base 500 is used for driving the bobbin 730 and the transmission grooved wheel 740 to be separated or attached to each other. The transmission sheave 740 is in transmission connection with the main drive of the winder 700. The drive sheave 740 is provided with guide grooves for facilitating the orderly winding of the yarn 900 onto the windings 730.

Referring to fig. 3, the winding base 500 is hinged by a third center shaft 510 and synchronously moves with the third center shaft 510. In this embodiment, the winding base 500 is hinged to the winding machine 700 by a third central shaft 510. Spool 730 is connected to spool winding base 500. In the present embodiment, the windings 730 comprise windings 730 shafts. The bobbin winding base 500 is formed with a bobbin connecting part 520 for snap-connecting with the bobbin 730.

When the stopping lever 410 is rotated clockwise, the first end of the stopping lever 410 moves upward and the second end of the stopping lever 410 moves downward. The bobbin winding base 500 is synchronously linked with the second end of the stopper rod 410, so that the bobbin winding base 500 rotates counterclockwise, thereby driving the bobbin 730 to be attached to the driving sheave 740. In a state where the windings 730 and the drive sheave 740 are attached to each other, the windings 730 start winding. During the winding process, the inclined teeth of the stopping rod 410 and the stopping block 340 formed on the second swing link 320 are always abutted against each other, and the bobbin 730 and the transmission sheave 740 are always attached to each other.

Referring to fig. 1 to 4, the circulation mechanism 600 includes a circulation reciprocating member, a circulation driving assembly, and the circulation reciprocating member is hinged to the first end of the second swing link 320 through the first central shaft 330. The circular driving component is used for driving the circular reciprocating component to swing back and forth, so that when the yarn pressing rod 220 does not monitor the yarn 900, the circular driving component enables the swinging mechanism 300 to reset. The cyclic reciprocating unit is a V-shaped rod 610, and the V-shaped rod 610 includes a first cyclic rod 611 and a second cyclic rod 612 connected to each other.

Referring to fig. 1 to 4, the circulation driving assembly includes a circulation spring 620, a circulation roller 630, and a roller driving part, and the circulation spring 620 is connected between the first circulation lever 611 and the housing 100. The circulating roller 630 is connected to one end of the second circulating rod 612, and the roller driving part is used for driving the circulating roller 630 to rotate in a guiding manner so as to drive the V-shaped rod 610 to move. The circulating spring 620 is used for driving the V-shaped rod 610 to reset.

The roller driving part comprises a circulating cam and a cam driving piece. The circulation roller 630 is in rolling contact with the profile of the circulation cam. The cam driver drives the circulation cam to rotate so that the circulation roller 630 is guided to move along the profile of the circulation cam. The cam driving part adopts a motor.

Referring to fig. 2 and 4, the first circulation bar 611 of the V-bar 610 protrudes to form a circulation protrusion capable of abutting against the pendulum 210 of the yarn monitoring mechanism 200. The circulation protrusion serves to jack up the bob 210 when the thread pressing bar 220 detects the absence of the yarn 900, thereby separating the second swing link 320 of the swing mechanism 300 and the first end of the stopping bar 410 from each other.

It will be appreciated that when the thread-pressing lever 220 detects the absence of the yarn 900, the thread-pressing lever 220 rotates counterclockwise and drives the pendulum 210 to rotate counterclockwise. When the pendulum 210 rotates to abut against the circular protrusion, the circular protrusion provides an upward force to the pendulum 210, so that the pendulum 210 rotates clockwise, and drives the first swing link 310 and the second swing link 320 of the swing mechanism 300 to rotate clockwise, so that the latch 340 formed on the second swing link 320 and the latch 410 are initially separated from each other.

Referring to fig. 3, the spooling base 500 further comprises a weight hammer 530, and the weight hammer 530 is fixedly connected to the third central shaft 510 for driving the spooling 730 to be separated from the driving sheave 740.

In the winding process, under the action of the self-locking structure, the inclined teeth of the stopping rod 410 are always abutted against the stopping block 340 formed on the second swing link 320, and the counterweight hammer 530 does not play a role.

When the winding is stopped or the yarn breakage occurs, the inclined teeth of the stopping lever 410 are primarily separated from the stopper 340 formed on the second swing link 320 by the circulation mechanism 600. Under the gravity of the weight hammer 530, the spooling base 500 rotates clockwise, and the spooling base 500 is synchronously linked with the second end of the stop lever 410, so that the stop lever 410 rotates counterclockwise, and thus the helical teeth of the stop lever 410 are sufficiently separated from the stop block 340 formed on the second swing link 320. Meanwhile, the bobbin winding base 500 rotates clockwise to drive the bobbin 730 and the transmission grooved wheel 740 to separate from each other. In a state where the winding 730 and the driving sheave 740 are separated from each other, the winding 730 stops the winding.

When the bobbin spindle position detection device 10 is used, the yarn 900 on the to-be-wound sub-yarn 710 needs to be drawn out, sequentially passes through the tension adjustment mechanism 720 and the bobbin spindle position detection device 10, and then the yarn 900 is wound on the bobbin 730.

The crimping lever 220 monitors in real time whether there is a yarn 900. When the yarn 900 is detected, the yarn 900 lifts the thread pressing rod 220, so that the thread pressing rod 220 rotates clockwise, and the pendulum 210 and the elastic piece 231 are synchronously driven to rotate clockwise. Because the elastic piece 231 is always clamped between the two limit blocks 234. When the elastic piece 231 rotates clockwise, the limiting plate 232 can be driven to move downwards.

When the pendulum 210 rotates clockwise, the swing mechanism 300 is synchronously driven to rotate clockwise. When the swing mechanism 300 rotates clockwise, the first swing link 310 and the second swing link 320 both rotate clockwise.

The swing link detecting mechanism 810 detects whether the first swing link 310 is normally operated in real time, and outputs a corresponding signal to the control module 800. The human-machine interface 830 receives the data from the control module 800, and constructs a configuration picture according to the received data to display the operation state of the bobbin 730 in real time. When the first swing link 310 is detected to be in the working position, the swing link detecting mechanism 810 outputs a signal for normal operation to the control module 800. The operator lifts the operating handle 420 to rotate the second central shaft 430 clockwise, and synchronously rotates the connecting cam and the protrusion of the connecting cam clockwise, thereby moving the stopping rod 410 clockwise.

When the stopping lever 410 is rotated clockwise, the first end of the stopping lever 410 moves upward and the second end of the stopping lever 410 moves downward. The bobbin winding base 500 is synchronously linked with the second end of the stopper rod 410, so that the bobbin winding base 500 rotates counterclockwise, thereby driving the bobbin 730 to be attached to the driving sheave 740.

After the bobbin 730 and the driving sheave 740 are attached to each other, the operator releases the operating handle 420, so that the inclined latch of the stopping rod 410 and the stopper 340 formed on the second swing link 320 are abutted against each other, and the stopping rod 410 is fixed relative to the second swing link 320.

During the winding process, the inclined teeth of the stopping rod 410 and the stopping block 340 formed on the second swing link 320 are always abutted against each other, so that the bobbin 730 and the transmission sheave 740 are always attached to each other.

When a yarn break occurs or the winding has been completed, the thread pressing lever 220 does not detect the yarn 900. At this time, the pressing rod 220 rotates counterclockwise to return to the initial position, and synchronously drives the pendulum 210 and the elastic piece 231 to rotate counterclockwise. When the elastic piece 231 rotates counterclockwise, the limiting plate 232 can be driven to move upward.

When the pendulum 210 rotates counterclockwise to abut against the circular protrusion, the circular protrusion provides an upward force to the pendulum 210, so that the pendulum 210 rotates clockwise, and the first swing link 310 and the second swing link 320 of the swing mechanism 300 are synchronously driven to rotate clockwise, so that the latch 340 formed on the second swing link 320 and the latch 410 are initially separated from each other.

Under the gravity of the weight hammer 530, the spooling base 500 rotates clockwise, and the spooling base 500 is synchronously linked with the second end of the stop rod 410, so that the stop rod 410 rotates counterclockwise, the inclined teeth of the stop rod 410 are sufficiently separated from the stop block 340 formed on the second swing link 320, and simultaneously the spooling base 500 drives the spools 730 to be separated from the transmission sheave 740. After the inclined teeth of the stopper lever 410 are sufficiently separated from the stopper 340 formed on the second swing link 320, the first swing link 310 and the second swing link 320 of the swing mechanism 300 return to the initial positions. The swing link detection mechanism 810 outputs a signal of abnormal operation to the control module 800, and the control module 800 controls the alarm mechanism 820 to trigger alarm.
