[0041] The following combines specific embodiments to further elaborate on the content of the present invention:

[0042] As Figure 1 shown, a feeding device for underwear production, which is used to supply the inner crotch required for underwear production. It includes a sorting unit 1, an edge wrapping unit 2, a loading unit 3, a transfer unit 4, and a lifting unit 5.

[0043] As Figure 2 and Figure 3 shown, the sorting unit 1 includes a material bin 11 and a material taking component 12. The inner crotches are stacked in the material bin 11. The material taking component 12 includes a material taking pressing block 121 and a material taking device 122. A material taking groove 1211 is opened at the bottom end of the material taking pressing block 121. The material taking pressing block 121 descends driven by a pressing block driving mechanism 123 to press the inner crotches tightly.

[0044] At this time, the part of the inner crotch in contact with the material taking pressing block 121 is compressed and thinned, while the part corresponding to the material taking groove 1211 is not pressed and thus maintains its original thickness. Therefore, this part will enter the material taking groove 1211. The material taking device 122 is connected with a material taking driver 1221. The material taking driver 1221 is used to drive the material taking device 122 to act, so that the material taking device 122 can enter the material taking groove 1211 and penetrate the part of the inner crotch located in the material taking groove 1211. Furthermore, the penetrated inner crotch can move with the pressing block driving mechanism 123 to complete the material taking operation.

[0045] The material taking device 122 includes a mounting frame 1222 and a body 1223. One end of the body 1223 is hinged to the mounting frame 1222 through a rotating shaft vertically installed on the side wall of the mounting frame 1222, enabling the body 1223 to swing along the vertical plane. The material taking pressing block 121 is fixed to the bottom of the mounting frame 1222 in the horizontal direction.

[0046] One end of the material taking driver 1221 is fixed to the side of the mounting frame 1222 opposite to the body 1223 and away from the material taking pressing block 121. The execution end of the material taking driver 1221 abuts against the middle part of the body 1223. A material taking needle 1224 is fixed to the end of the body 1223 away from the hinged end in the direction towards the material taking pressing block 121. When the material taking driver 1221 operates, it can drive the body 1223 to swing towards the material taking pressing block 121, so that the material taking needle 1224 enters the material taking groove 1211 and penetrates the inner crotch therein. A reset member 124 is provided in cooperation with the material taking driver 1221. The two ends of the reset member 124 are respectively connected to the mounting frame 1222 and the body 1223 ( Figure 3 connected at the a end and the a` end in the figure). When the execution end of the material taking driver 1221 does not exert a thrust on the body 1223, the reset member 124 pulls the body 1223, so that the material taking needle 1224 leaves the material taking groove 1211. In this embodiment, the material taking driver 1221 adopts a cylinder, and the reset member 124 adopts a spring.

[0047] As Figure 1 shown, the loading unit 3 includes a first carrier 31 and a second carrier 32. Both the first carrier 31 and the second carrier 32 are used for loading the inner crotch, and an adsorption device is provided to be able to adsorb the inner crotch placed thereon. The first carrier 31 and the second carrier 32 are respectively arranged corresponding to the sorting unit 1 and the lifting unit 5.

[0048] Combined with Figure 2 shown, a sorting transfer mechanism 13 is slidably connected to the top end of the material taking device 122. The sorting transfer mechanism 13 drives the material taking device 122 to carry the penetrated inner crotch and place it on the first carrier 31.

[0049] The transfer unit 4 is used for transferring the inner crotch between the first carrier 31 and the second carrier 32, and includes a transfer track 41 and a clamping plate mechanism 44. Among them, the two ends of the transfer track 41 are respectively arranged corresponding to the first carrier 31 and the second carrier 32, and a transfer slider 42 is arranged in cooperation with the transfer track 41. The transfer slider 42 runs along the length direction of the transfer track 41 driven by a transfer driver.

[0050] Combined with Figure 4As shown in the figure, a clamping plate mechanism 44 is provided on the transfer slider 42 through a feed driving mechanism 43. Among them, the clamping plate mechanism 44 includes a cooperatively arranged upper clamping plate 441 and a lower clamping plate 442. The upper clamping plate 441 and the lower clamping plate 442 can clamp the edge of the inner crotch under the drive of a clamping plate driver 443. The feed driving mechanism 43 drives the clamping plate mechanism 44 to move towards or away from the loading unit 3. When the clamping plate mechanism 44 places the inner crotch on the second stage 32, the feed driving mechanism 43 drives the clamping plate away from the second stage 32, so as to provide an operating space for the edge folding process.

[0051] As Figure 5 shown in the figure, the edge folding unit 2 is used for folding and hemming the edge of the inner crotch, and has an edge hemming positioning mechanism 21 and an edge hemming driving mechanism 22. The edge hemming positioning mechanism 21 includes a positioning pressing plate 211. One end of the positioning pressing plate 211 is connected to a positioning lifter 212. The positioning lifter 212 drives the positioning pressing plate 211 to perform a lifting motion, and makes the positioning pressing plate 211 abut against the inner crotch placed on the second stage 32. At this time, the straight edge line outside the positioning pressing plate 211 will serve as the positioning end when hemming the edge of the inner crotch. The positioning lifter 212 is fixed on an avoidance mechanism 23. The avoidance mechanism 23 includes an avoidance guide rail 231 arranged in the horizontal direction. An avoidance mounting plate 232 is slidably fitted on the avoidance guide rail 231. The avoidance mounting plate 232 slides along the length direction of the avoidance guide rail 231 under the drive of an avoidance driver 233. One end of the lifting driver is fixed to the avoidance mounting plate 232.

[0052] The edge hemming driving mechanism 22 has an edge hemming plate 221. The lower surface of the edge hemming plate 221 is higher than the upper surface of the positioning pressing plate 211 when the positioning pressing plate 211 abuts against the inner crotch, so that when the edge hemming plate 221 moves horizontally under the drive of an edge hemming driver 222, it will not interfere with the positioning pressing plate 211.

[0053] Combined with Figure 7 shown in the figure, when the edge hemming driver 222 does not act, the edge hemming plate 221 is fitted outside the second stage 32. When the clamping plate mechanism 44 in the transfer unit 4 places the inner crotch on the second stage 32, the edge of the inner crotch that needs to be hemmed will cover the edge hemming plate 221. When the edge hemming driver 222 drives the edge hemming plate 221 to move towards the middle of the inner crotch, with the cooperation of the positioning pressing plate 211, the edge of the inner crotch covering the edge hemming plate 221 will be naturally folded and cover the positioning pressing plate 211. Subsequently, the avoidance driver 233 drives the avoidance mounting plate 232 to drive the positioning pressing plate 211 to retract, so that the positioning pressing plate 211 is withdrawn from the folded inner crotch, and the inner crotch completes the edge hemming operation on the second stage 32.

[0054] Combined with Figure 1 and Figure 6As shown in the figure, the lifting unit 5 is connected to the bottom end of the second carrier 32 and is used to send the second carrier 32 into the upper assembly platform 6 so that the inner crotch can perform subsequent processes. The lifting unit 5 includes a lifting slider 51 fixed in the vertical direction. A lifting driver 52 is fixed to the lifting slider 51 in the vertical direction. A chute is formed on one side of the lifting slider 51 and a lifting track 53 is slidably arranged therein. The top end of the lifting track 53 and the execution end of the lifting driver 52 are both fixed to the second carrier 32. The assembly platform 6 is provided with a sewing jig 62 for carrying the main material and a sewing device 63. The sewing jig 62 carries the main material and covers the inner crotch, and the main material and the inner crotch are sewn together by the sewing device 63.

[0055] A sewing jig 62 for carrying the main material and a sewing device 63 are arranged on the assembly platform 6. The sewing jig 62 carries the main material and covers the inner crotch, and the main material and the inner crotch are sewn together by the sewing device 63.
