Referring to fig. 1, 2 and 3, the present application provides a yarn searching device for searching for broken yarn ends on a surface of a bobbin 200, which comprises a base 2, wherein the base 2 is provided with a yarn searching device 1 and a bobbin grabbing device 3; the hunting device 1 includes a base 10, a barrel 20, and a winding member 40; the cylinder 20 is a hollow cylinder and is fixedly arranged on the base 10, the cylinder 20 is provided with at least one opening, and the opening can be connected with the air suction piece; the winding part 40 is arranged in the barrel 20, a wire sucking opening 21 is formed in the inner side and the outer side of the side surface of the barrel 20 in a penetrating manner, and the wire sucking opening 21 is formed along the axial direction of the barrel 20; the bobbin gripping device 3 is capable of gripping the bobbin 200 on the textile machine to correspond to the thread suction port 21 and driving the bobbin 200 to rotate.

When the yarn breakage problem occurs to the yarn tube 200 on the textile machine, the yarn tube grabbing device 3 can grab and move the yarn tube 200 with the broken yarn to correspond to the yarn suction port 21;

an air suction piece is connected to the opening of the barrel 20, and after the air suction piece is started, air in the barrel 20 can be outwards pumped out along the opening, so that negative pressure is generated in the barrel 20, and air outside the barrel 20 enters the barrel 20 through the wire suction port 21 under the action of internal and external pressure difference;

the bobbin grabbing device 3 can also drive the bobbin 200 to rotate, so that the outer circumferential surface of the bobbin 200 can be opposite to the thread sucking opening 21, and when the bobbin 200 rotates until the broken thread is opposite to the thread sucking opening 21, the broken thread is sucked into the bobbin body 20 and is adsorbed and wound by the winding piece 40, so that the broken thread is captured.

In some embodiments, the winding member 40 is a winding rod with bristles, or a winding rod with an adhesive layer, or the like, so long as it is capable of adsorbing the broken wire end into the barrel 20, which is not particularly limited herein.

In the embodiment shown in fig. 2, the thread sucking opening 21 is elongated along the axial direction of the barrel 20, and the length of the thread sucking opening 21 is greater than the length of the bobbin 200;

the length of the thread suction opening 21 is longer than that of the bobbin 200, and the bobbin gripping device 3 is matched to drive the bobbin 200 to rotate, so that along with the rotation of the bobbin 200, any position of the outer peripheral surface of the bobbin 200 can be opposite to the thread suction opening 21, thereby further reducing the possibility of missing broken thread ends and further increasing the success rate of thread end capturing;

in addition, on the premise that the length of the thread sucking opening 21 is ensured to be larger than that of the bobbin 200, the thread sucking opening 21 is opened to be long in the axial direction of the barrel body 20, so that the width of the thread sucking opening 21 can be reduced, the opening area of the thread sucking opening 21 is reduced, the suction force of the thread sucking opening 21 on broken thread ends is increased, and the success rate of thread end capturing is further increased.

In the embodiment shown in fig. 4, the bobbin gripping device 3 includes a driving assembly 310 fixed on the base 2, a third motor 320 fixed on a moving end of the driving assembly 310, and a clamping jaw assembly 330 fixed on a driving section of the third motor 320, where the clamping jaw assembly 330 can clamp the bobbin 200.

The driving assembly 310 can drive the clamping jaw assembly 330 to move between the textile machine and the hunting device so as to clamp the bobbin 200 to correspond to the yarn suction opening 21, and the third motor 320 can drive the clamping jaw assembly 330 so as to drive the bobbin 200 clamped by the clamping jaw assembly 330 to rotate around the central axis of the bobbin 200.

In the embodiment shown in fig. 1 and 4, the hunting device further comprises a mechanical arm 4 provided to the base 2, the mechanical arm 4 being capable of gripping the yarn between the bobbin 200 and the winding member 40; the mechanical arm 4 can clamp and tear the yarn between the yarn hunting device 1 and the yarn bobbin 200, and the yarn clamped by the mechanical arm 4 after the yarn is torn is positioned on a section of yarn connected with the yarn bobbin 200 to finish yarn hunting.

In the above embodiment, the hunting apparatus further includes the first motor 30 and the hunting moving device 5; the first motor 30 is fixedly arranged at one axial end of the barrel 20, and can drive the winding piece 40 to rotate around the axis of the winding piece; the hunting moving device 5 is fixedly arranged on the base 2, the base 10 is fixedly arranged at the moving end of the hunting moving device 5, and the hunting moving device 5 can drive the hunting device 1 to be close to or far away from the bobbin 200.

The first motor 30 can drive the winding member 40 to rotate, so that broken thread ends adsorbed on the winding member 40 rotate along with the winding member 40, and further, yarn is pulled out from the bobbin 200 and wound on the winding member 40, so that the connection stability between the yarn and the winding member 40 is improved, and the situation that broken thread ends fall off due to unstable adsorption is avoided;

after the yarn is wound to the winding part 40, the mechanical arm 4 clamps the yarn between the yarn hunting device 1 and the bobbin 200, after the clamping is completed, the yarn hunting moving device 5 drives the yarn hunting device 1 to move to one side far away from the bobbin 200, so that the yarn between the clamping positions of the yarn hunting device 1 and the mechanical arm 4 is torn, and the yarn clamped by the mechanical arm 4 after the yarn is torn is always one end connected with the bobbin 200 due to the fact that the position is located between the clamping positions of the yarn hunting device 1 and the mechanical arm 4.

Of course, the above-described broken thread gripping step after thread end catching may be realized by other structures, for example, by providing a gripping arm, a cutting arm, or the like, as long as the yarn between the yarn hunting device 1 and the bobbin 200 can be broken and a piece of yarn connected to the bobbin 200 can be obtained.

In the embodiment shown in fig. 5, a torque sensor 50 is fixedly arranged between the winding member 40 and the driving end of the first motor 30;

in the process of driving the winding member 40 to rotate and wind by the first motor 30, if the broken thread is successfully adsorbed on the winding member 40, the first motor 30 drives the winding member 40 to rotate and simultaneously pulls out the yarn from the yarn tube 200, and the torque detected by the torque sensor 50 is relatively larger; if the wire end of the broken wire is not successfully adsorbed on the wire winding member 40, the first motor 30 only needs to drive the wire winding member 40 to rotate, and the torque detected by the torque sensor 50 is relatively small;

therefore, the torque detected by the torque sensor 50 can be used for judging whether the wire head is successfully captured or not in the winding process, so that the situation that the wire head is not successfully captured and then the subsequent operation is started to cause the idle running of the hunting equipment is avoided, the hunting success rate is effectively increased, and the hunting efficiency of the equipment is improved.
