Description

Technical Field

[0001] The utility model belongs to the field of trademark tape production equipment, in particular to a trademark tape warping yarn breakage detection device. Background Art

[0002] A warping machine is used in the production process of trademark tapes. The warp yarn drawn from the bobbin on the creel first passes through a broken end detector, then through a yarn guide porcelain plate, then through a yarn guide rod, through a telescopic reed, around a length measuring roller, and then wound onto a warp beam.

[0003] The existing broken end detector is a photoelectric structure, that is, it detects whether the warp yarn is broken through a corresponding infrared sensor. When the warp yarn is not broken, the light emitted by the transmitting end of the infrared sensor is blocked by the warp yarn, and the receiving end of the infrared sensor does not receive sufficient light intensity. The broken end detector does not generate a signal, and the warping machine operates normally; when the warp yarn is broken, the light is not blocked and the receiving end of the infrared sensor receives sufficient light intensity, the broken end detector generates a signal, and the warping machine stops.

[0004] The existing broken end detector has the following defects: since the warp yarn moves at high speed on the warping machine, lint will be formed due to friction, and these lints carry static electricity generated by friction and are easily adsorbed on objects. Whether they are adsorbed on the transmitting end or the receiving end of the infrared sensor, they will isolate the light transmission between the transmitting end and the receiving end. Even if the warp yarn breaks, the broken end detector cannot generate a signal and the warping machine cannot be stopped in time. Utility Model Content

[0005] The purpose of the utility model is to provide a warping yarn breakage detection device for trademark tapes. The utility model has the advantages of ensuring that a signal is generated when the warp yarn breaks to stop the warping machine, and has low energy consumption and convenient maintenance.

[0006] The technical solution of the utility model is as follows: a trademark tape warping yarn breakage detection device comprises an infrared sensor with a transmitting end and a receiving end, a glass tube is arranged between the transmitting end and the receiving end, an air intake pipeline connected to a compressed air device is arranged on the side wall of the glass tube, a timing switch is arranged on the air intake pipeline, and the timing switch is used to allow the compressed air on the compressed air device to enter the glass tube at a regular time.

[0007] In the aforementioned trademark tape warping yarn breakage detection device, the two sides of the glass tube extend outwards respectively to form a first blind hole for installing the transmitting end and a second blind hole for installing the receiving end.

[0008] In the aforementioned trademark tape warping and yarn break detection device, a measuring point is formed between the transmitting end and the receiving end, and the air intake pipeline includes an inclined tube extending from the side wall of the glass tube, the inner end of the inclined tube is close to the measuring point, and the outer end of the inclined tube is far away from the measuring point. The inclined tube is connected to the compressed air equipment through a timing switch.

[0009] In the aforementioned trademark tape warping yarn breakage detection device, the outer end of the oblique tube is bent to form a tube joint, and the axis of the tube joint is perpendicular to the axis of the glass tube.

[0010] In the aforementioned trademark tape warping yarn breakage detection device, the air inlet pipeline also includes a first hose connected to the pipe joint and a second hose connected to the compressed air device, and the timing switch is located between the first hose and the second hose.

[0011] In the aforementioned trademark tape warping yarn break detection device, the timing switch includes a shell, one side of the shell is connected to the first hose, the other side of the shell is connected to the second hose, a reduction motor is provided on the outside of the shell, a sphere is provided inside the shell, the output end of the reduction motor is connected to the sphere, a through hole is provided in the sphere, and the first hose is connected to the second hose through the through hole.

[0012] In the aforementioned trademark tape warping yarn breakage detection device, a polygonal column-shaped groove is provided on the outer peripheral surface of the sphere, a polygonal column-shaped driving rod is provided in the groove, and the driving rod is connected to the output end of the reduction motor.

[0013] Compared with the prior art, the utility model sets a glass tube for the warp yarn to pass through between the transmitting end and the receiving end of the infrared sensor, sets an air intake pipeline on the side wall of the glass tube, and uses compressed gas to blow high-pressure airflow into the glass tube regularly to clean the inner hole of the glass tube and keep the absence of lint between the transmitting end and the receiving end. The infrared sensor can generate a signal after the warp yarn breaks to ensure that the warping machine is shut down immediately. Since the compressed gas enters the glass tube periodically, the amount of compressed gas is small, the starting frequency of the compressed gas equipment is low, and the energy consumption is low. In addition, the output end of the reduction motor is plug-in connected to the ball through the driving rod. When the reduction motor fails, it is easy to replace and facilitate maintenance. In summary, the utility model has the advantages of ensuring that a signal is generated when the warp yarn breaks to shut down the warping machine, and it has low energy consumption and is easy to maintain.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0018] Embodiment. A device for detecting yarn breakage during warping of a trademark tape, such as Figure 1 As shown, the infrared sensor comprises a transmitting end 1 and a receiving end 2, a glass tube 3 is arranged between the transmitting end 1 and the receiving end 2, both ends of the inner hole of the glass tube 3 are rounded, and tubular objects are extended outward from both sides of the glass tube 3 to form a first blind hole 6 and a second blind hole 7. The transmitting end 1 is tightly plugged into the first blind hole 6, and the receiving end 2 is tightly plugged into the second blind hole 7.

[0019] An air inlet pipe 4 connected to a compressed air device is provided on the side wall of the glass tube 3. A timer switch 5 is provided on the air inlet pipe 4. The timer switch 5 is used to allow the compressed air on the compressed air device to enter the glass tube 3 at a fixed time. The compressed air device is, for example, an air compressor.

[0020] A measurement point is formed between the transmitter 1 and the receiver 2, such as Figure 2 As shown, the air inlet pipeline 4 includes an oblique tube 8 extending from the side wall of the glass tube 3, the inner end of the oblique tube 8 is close to the measuring point, and the outer end of the oblique tube 8 is far away from the measuring point. The outer end of the oblique tube 8 is bent to form a pipe joint 9, and the axis of the pipe joint 9 is perpendicular to the axis of the glass tube 3.

[0021] The air intake pipeline 4 further includes a first hose 10 connected to the pipe joint 9 and a second hose 11 connected to the compressed air device. The timer switch 5 is located between the first hose 10 and the second hose 11 .

[0022] The timer switch 5 includes a housing 12, one side of the housing 12 is connected to the first hose 10, the other side of the housing 12 is connected to the second hose 11, a miniature reduction motor 13 is arranged on the outside of the housing 12, the reduction motor 13 is screwed to the housing 12, the speed of the reduction motor 13 is 2-5r / min, a sphere 14 is arranged in the housing 12, a through hole 15 is arranged in the sphere 14, and the first hose 10 is connected to the second hose 11 through the through hole 15. A polygonal prism-shaped groove 16 is arranged on the outer peripheral surface of the sphere 14, and a polygonal prism-shaped driving rod 17 is arranged in the groove 16, and the driving rod 17 is connected to the output end of the reduction motor 13. The timer switch 5 has a simple structure and a relatively low cost.

[0023] Working principle: The warp yarn 18 passes through the glass tube 3, the light emitted by the transmitting end 1 is blocked by the warp yarn 18, the light intensity received by the receiving end 2 is insufficient, and the infrared sensor does not generate a signal. When the warp yarn 18 breaks, the warp yarn 18 on the front side continues to be pulled, and the warp yarn 18 on the rear side loses traction and falls out of the glass tube 3 under the action of gravity. The light emitted by the transmitting end 1 is not blocked, and the light intensity received by the receiving end 2 is sufficient. The infrared sensor generates a signal and the warping machine stops.

[0024] The reduction motor 13 works continuously, and drives the sphere 14 to rotate through the driving rod 17. When the two ends of the through hole 15 are respectively connected to the first hose 10 and the second hose 11, the compressed air comes out of the compressed air device, and enters the glass tube 3 through the second hose 11, the through hole 15, the first hose 10, the pipe joint 9, and the inclined tube 8 in sequence, and is discharged from one end of the glass tube 3 to blow away the fluff that may exist in the glass tube 3. The air is blown 2-5 times per minute. When the warp yarn 18 is broken, the receiving end 2 can receive sufficient light intensity. In most cases, the first hose 10 and the second hose 11 are blocked by the sphere 14 and are not connected, thereby reducing the amount of compressed air used.
