[0025] As shown in Figure 1 , the embodiment of the present application provides a yarn inserting robot, which comprises a vibrating hopper 1, a tube yarn feeding lifting mechanism 2, an arrangement device 3 and a grabbing and throwing device 4.

[0026] As shown in Figure 2 and Figure 3 , the vibrating hopper 1 is used to receive the tube yarn from the tube yarn feeding vehicle and provide the tube yarn without entangled yarn to the tube yarn feeding lifting mechanism 2, and the vibrating hopper 1 comprises a hopper body 10, a sliding material plate 11, a vibrating bottom plate 12, a vibrating mechanism 13, a thread end negative pressure suction mechanism 14, a cutting mechanism 15 and a lifting mechanism 16.

[0027] The upper part of the hopper body 10 is provided with a feeding port, and the funnel-shaped bottom of the hopper body is provided with a discharging port. The hopper body 10 can comprise a four cuboid formed by four plate bodies. As shown in Figure 1 , the left side of the four cuboid is the feeding side of the vibrating hopper 1, and the right side is the discharging side of the vibrating hopper 1.

[0028] As shown in Figure 4 , the upper opening of the four cuboid is the feeding port of the hopper, and the four cuboid forms the discharging port of the tube yarn by cooperating with the sliding material plate 11 and the vibrating bottom plate 12.

[0029] The slide plate 11 is arranged in the silo body 10 to make the yarns from the yarn carrier slowly slide down. The angle between the inclined surface where the upper surface of the slide plate 11 is located and the horizontal ground is an acute angle. In order to shorten the transport path of the yarns, the slide plate 11 is fixed on the plate body at the discharge side of the silo body 10.

[0030] The vibrating bottom plate 12 is arranged below the slide plate 11 and cooperates with the bottom surface of the slide plate 11 to form the discharge port. The angle between the inclined surface where the upper surface of the vibrating bottom plate 12 is located and the horizontal ground is an acute angle. In order to shorten the transport path of the yarns, the vibrating bottom plate 12 is fixed on the plate body at the feeding side of the silo body 10. The inclined direction of the vibrating bottom plate 12 is opposite to that of the slide plate 11.

[0031] The vibrating mechanism 13 can be directly arranged on the bottom surface of the vibrating bottom plate 12 and control the vibration of the vibrating bottom plate 12. The vibrating mechanism 13 can also be indirectly connected with the vibrating bottom plate 12, for example, the vibrating mechanism 13 can indirectly control the vibration of the vibrating bottom plate 12 through a guide rod.

[0032] The thread negative pressure suction mechanism 14 is arranged at the tail end of the vibrating bottom plate 12. The negative pressure suction mechanism 14 forms a negative pressure suction at the bottom of the vibrating bottom plate 12 to suck the thread of the yarns passing through.

[0033] The shearing mechanism 15 is arranged in a spaced manner with the vibrating bottom plate 12 to form a discharge gap at a certain distance and interval. The shearing mechanism 15 is used to shear the thread.

[0034] The lifting mechanism 16 is arranged between the shearing mechanism 15 and the vibrating bottom plate 12 and below the discharge gap. The lifting mechanism 16 is used to control the frequency of the yarns with the thread being adsorbed to be transported to the shearing mechanism 15.

[0035] The yarn feeding lifting device 2 is installed at the discharge side of the vibrating silo 1. The yarn feeding lifting device 2 includes a feeding side and a discharging side, and the feeding side faces the discharge side of the vibrating silo 1. The bottom of the yarn feeding lifting device 2 is fixedly connected with the discharge side of the shearing mechanism 15. The yarn feeding lifting device 2 is used to vertically lift the yarns to a predetermined height.

[0036] The arrangement device 3 is used to arrange the yarns at the predetermined height so that the large and small heads of the yarns are arranged in a set manner.

[0037] The grabbing and feeding device 4 is used to grab the yarns arranged by the arrangement device 3 to put the yarns into the yarn library.

[0038] When the yarns in the yarn carrier drop onto the slide plate 11 of the vibrating silo 2, the slide plate 11 makes the yarns slowly slide onto the vibrating bottom plate 12, and then the vibration of the vibrating bottom plate 12 is controlled by the vibrating mechanism 13 to realize the orderly rolling of the yarns on the vibrating bottom plate 12.

[0039] When the cop is rolling on the vibrating base 12, the tail end thread negative pressure suction mechanism 14 generates negative pressure and sucks the thread of the passing cop, the thread of the cop is sucked, and the cop continues to roll down along the vibrating base 12 and falls into the material falling gap between the vibrating base 12 and the cutting mechanism 15.

[0040] The material falling gap can temporarily accommodate the cop. When the downstream equipment does not need the cop, the lifting mechanism 16 does not perform the lifting operation, at this time the cop is stored in the material falling gap; when the downstream equipment needs the cop, the lifting mechanism 16 performs the lifting operation, at this time the cop is lifted from the material falling gap until it exceeds the height of the cutting mechanism 15, and then the cop passes over the upper end of the cutting mechanism 15.

[0041] Since the thread is still sucked by the thread negative pressure suction mechanism 14 when the cop passes over the cutting mechanism 15, the cutting mechanism 15 can cut the thread of the cop and obtain the cop without thread winding.

[0042] The cop feeding and lifting device 2 vertically lifts the cop to a predetermined height.

[0043] The arrangement device 3 arranges the cop at the predetermined height, so that the large and small heads of the cop are arranged in a set manner.

[0044] The grabbing and feeding device 4 is used to grab the cop arranged by the arrangement device 3 and put the cop into the yarn library.

[0045] In the embodiment, the vibrating material bin is provided with the sliding material plate with opposite inclination angles and the vibrating base. The cop first falls on the sliding material plate, the sliding material plate reduces the falling speed of the cop to the vibrating base, and the stacked cop in the process of rolling on the sliding material plate is separated, so that multiple cots are prevented from being stacked and falling on the vibrating base, and the thread negative pressure suction mechanism at the bottom of the vibrating base can suck the thread of all the cots. In addition, the vibrating base makes the cop orderly roll by vibrating, and the winding of the yarn of the cop is avoided; the thread negative pressure suction mechanism provided on the vibrating base can suck the thread of the passing cop, the lifting mechanism controls the cop with the sucked thread to be transported to the cutting mechanism, the cop passes over the cutting mechanism, and the cutting mechanism cuts the thread, so that the cop without thread winding is obtained.

[0046] As shown in FIG. 1, Figure 4 In an embodiment, the thread negative pressure suction mechanism 14 includes at least one slit 1401 provided on the vibrating base 12 and a suction unit provided below the slit 1401.

[0047] As shown in FIG. 1, Figure 3 The suction unit includes a negative pressure suction machine and a negative pressure suction box 1402.

[0048] The negative pressure suction box 1402 is located below the slit 1401 and is used to wrap the slit 1401 and form a sealed space.

[0049] The negative pressure suction machine evacuates air from the negative pressure suction box 1402, creating a negative pressure space within the sealed area, thereby sucking up the yarn ends passing through the slit 1401. In one embodiment, a negative pressure suction head 1403 is provided at the bottom of the negative pressure suction box 1402. The negative pressure suction machine evacuates air from the negative pressure suction box 1402 through the negative pressure suction head 1403, thus eliminating the need for multiple negative pressure suction heads to suck up yarn ends at every point of the slit 1401. Furthermore, the sealed space is small, and after the negative pressure space is formed, a large pressure difference is created between the pressure inside the negative pressure space and the pressure above the slit 1401, resulting in strong suction from the suction unit.

[0050] In one embodiment, the suction unit further includes a thread-end blocking member, which prevents the thread end of the yarn tube sucked by the suction unit 1402 from entering the negative pressure suction machine, thus avoiding clogging of the negative pressure suction machine by the thread end of the yarn tube. The thread-end blocking member can be set at any position between the negative pressure suction box and the negative pressure suction machine, for example, on the negative pressure suction head 1403.

[0051] like Figure 4 As shown, in one embodiment, the lifting mechanism 16 includes a lifting plate 1601 and a lifting unit 1602.

[0052] The lifting plate 1601, the vibrating base plate 12, and the shearing mechanism 15 form a temporary storage area for accommodating yarn tubes. The lifting unit 1602 drives the lifting plate 1601 to lift the yarn tubes in the temporary storage area and pass them over the shearing mechanism 15. The lifting plate 1601 can move up and down. When downstream equipment needs yarn tubes, the lifting unit 1602 drives the lifting plate 1601 to move upward, lifting the yarn tubes on the lifting plate 1601 until they finally pass over the shearing mechanism 15.

[0053] like Figure 5 As shown, in one embodiment, the shearing mechanism 15 includes a blade assembly 151 and a drive motor 152.

[0054] The drive motor 152 can be located below the blade assembly 151, or it can be connected to the blade assembly 151 via a circuit. The drive motor 152 drives the blade assembly to cut the passing yarn tube and the sucked-up thread ends, thereby cutting off the sucked-up thread ends.

[0055] In one embodiment, the blade assembly 151 includes a plurality of fixed blades 1511 and a plurality of movable blades 1512. The drive motor 152 drives the movable blades 1512 to close toward the fixed blades 1511, thereby achieving the cutting of the yarn tube and the sucked-up thread ends.

[0056] likeFigure 2 As shown, in an embodiment, the preset bin 17 is arranged on the non-lifting mechanism side of the cutting mechanism 15, and the preset bin 17 is used to accommodate the tubes of yarn that pass through the cutting mechanism 15. The tubes of yarn accommodated in the preset bin 17 are all tubes of yarn without wound yarn. The preset bin 17 is fixedly connected with the feeding opening of the tube of yarn feeding and lifting device 2.

[0057] In an embodiment, the preset bin 17 is provided with a photoelectric sensor at the bottom, the photoelectric sensor is used to sense the condition of the tubes of yarn accommodated in the preset bin 17, and generate a signal for controlling the operation of the lifting mechanism 16.

[0058] When the tubes of yarn in the preset bin 17 are lower than a preset value, the photoelectric sensor transmits a signal to the jacking unit 1602 in the lifting mechanism 16, the jacking unit 1602 drives the lifting plate 1601 to move upward, and the tubes of yarn on the lifting plate 1601 are lifted, and finally the tubes of yarn pass through the cutting mechanism 15 and fall into the preset bin 17.

[0059] When the tubes of yarn in the preset bin 17 are higher than a preset value, the photoelectric sensor does not act, and the tubes of yarn are temporarily placed in the temporary storage area.

[0060] In an embodiment, the inclination angle of the feeding plate 11 is 30°-45°, which is beneficial to the separation of the stacked tubes of yarn and the transmission of the non-stacked tubes of yarn to the vibrating base plate 12.

[0061] The inclination angle of the vibrating base plate 12 is 30°-45°, which is beneficial to the low rolling speed of the tubes of yarn on the vibrating base plate 12, and the thread end negative pressure suction device 14 can more efficiently suck the thread end of the tubes of yarn, and avoid that the rolling speed of the tubes of yarn is too fast and the thread end negative pressure suction device 14 cannot suck the thread end of the tubes of yarn.

[0062] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed in the present application can be easily thought by those skilled in the art, and should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
