The induction is an induction switch 721. The sensor switch 721 may be a photoelectric proximity switch, an inductive proximity switch, a Hall effect proximity switch, or the like. In this embodiment, an inductive proximity switch is employed. It is controlled in conjunction with the vacuum suction cup 1 720 , the vacuum suction cup 2 722 , and the vacuum suction cup 3 723 by a main controller, so that the knitted glove 30 is detected at close range by the sensor switch 721 just as it is about to fall, and is attracted to the knitted glove 30 by the negative pressure of the vacuum suction cups.

[0043] In order to automatically place the knitted gloves 30 stacked together to improve the degree of automation, the automatic glove stacking device 8 includes a glove receiving plate 81 with a grid groove for the suction cup fixing plate 719 to place the knitted gloves 30, and a glove stacking device 825 with a plurality of glove stacking positions 828. The glove stacking positions 828 are composed of a plurality of stacking rods arranged in rows at intervals and suspended on the glove stacking device 825 at one end. The stacking rod in this embodiment is a circular shaft 88. The position of the circular shaft 88 corresponds to the grid groove, and the depth and width of the grid groove are both greater than the diameter of the circular shaft 88. The circular shaft 88 can also be replaced by a plate-like object arranged at intervals.

[0044] The glove receiving plate 81 is connected to the left and right driving devices 826, and the left and right driving devices 826 can drive the glove receiving plate 81 to slide horizontally into the glove stacking position 828 through the grid groove.

The glove stacking positions 828 are arranged on the 3 groups on the right side of the left side plate 817 and the 3 groups on the left side of the right side plate 814 and correspond to each other. The synchronous belt electric slide 85 is arranged on the rear side plate 84.

[0048] The glove receiving and placing mechanism 735 in the automatic glove receiving and placing drive device 7 also includes a rotating block 72, a connecting block 717, a worm gear 725 and a worm 74. The connecting block 717 is fixed to the rotating block 72, the rotating shaft 73 is fixed to the rotating block 72 and is rotatably connected to the bearing seat 731, the left end of the rotating shaft 73 is connected to the worm gear 725, the upper motor base plate 715 is arranged on the side of the bearing seat 731, and the driving shaft of the upper motor 716 is connected to the worm 74 after passing through the upper motor base plate 715.

[0049] Specifically, the connecting block 717 is provided with cylinders 729 distributed along its length. The telescopic rods of the cylinders 729 are connected to the suction cup fixing plate 719. The suction cup fixing plate 719 is positioned at the telescopic position of the cylinders 729.

[0050] In this embodiment, the vertical drive device 736 includes a screw transmission assembly 714, a lower motor base plate 77, a screw synchronous wheel 78, a motor synchronous wheel 710 and a synchronous belt 79, etc. The glove receiving and releasing mechanism 735 is installed on the screw transmission assembly 714, and the screw transmission assembly 714 can drive the glove receiving and releasing mechanism 735 to move back and forth.

[0051] Specifically, the screw transmission assembly 714 includes a screw 714B and a screw nut 714A fixed on the slide. The lower motor 712 is driven and connected to the screw 714B. The bearing seat 731 is fixed to the screw nut 714A of the screw transmission assembly 714. The screw synchronous wheel 78 is combined with the screw 714B of the screw transmission assembly 714. The driving shaft of the lower motor 712 is combined with the motor synchronous wheel 710 after passing through the adapter plate 711 and the lower motor base plate 77. The synchronous belt 79 is arranged between the screw synchronous wheel 78 and the motor synchronous wheel 710. The lower motor 712 can drive the screw 714B to rotate so that the glove receiving and placing mechanism 735 can be lifted and lowered back and forth.

[0052] The working principle of this embodiment is as follows: the glove knitting machine drives the front head 5 and the rear head 6 to move back and forth through the direct drive mechanism 11, and also drives the knitting needles arranged in the needle grooves of the needle plate 4 to move, and cooperates with the push rod transmission mechanism 10, the needle selection mechanism, etc. to participate in knitting. The glove knitting machine first completes the knitting of the finger and palm parts of the knitted glove 30. When bifurcation is required, the fork and knife transmission mechanism 17 and the scissors transmission mechanism 9 cooperate to knit the cuff part. When the knitted glove 30 is about to fall, as shown in FIG. Figure 4 As shown, the drive shaft of the lower motor 712 of the vertical drive mechanism 736 rotates, driving the motor synchronous wheel 710, the synchronous belt 1 79 and the screw synchronous wheel 78 to rotate synchronously. Since the screw synchronous wheel 78 is fixedly connected to the screw 714B of the screw transmission assembly 714, the screw 714B also drives the screw nut 714A and the glove receiving and releasing mechanism 735 to move vertically upward, and then the telescopic position of the cylinder 729 moves upward, driving the suction cup fixing plate 719, the vacuum suction cup 1 720, the induction switch The switch 721, the second vacuum suction cup 722, and the third vacuum suction cup 723 move synchronously. Then, the first vacuum suction cup 720, the sensor switch 721, the second vacuum suction cup 722, and the third vacuum suction cup 723 correspond to the knitted glove 30. First, the sensor switch 721 detects the palm of the knitted glove 30 and sends a detection signal. If the knitted glove 30 is detected to be present, the first vacuum suction cup 720, the second vacuum suction cup 722, and the third vacuum suction cup 723 apply negative pressure to the knitted glove 30. Figure 5 Shown and Figure 1 As shown, after the glove receiving and placing mechanism 735 attracts the knitted glove 30, the telescopic position of the cylinder 729 retracts, and then the driving shaft of the lower motor 712 reverses, driving the motor synchronous wheel 710, the synchronous belt 1 79 and the screw synchronous wheel 78 to rotate synchronously, and the screw 714B of the screw transmission assembly also drives the screw nut 714A and the glove receiving and placing mechanism 735 to move vertically downward until they reach a preset position. At the same time, the second camera 14 takes a picture of one side of the knitted glove 30 attracted by the negative pressure and transmits the image to the terminal display 15; Figure 6 As shown, the driving shaft of the upper motor 716 rotates, driving the worm 74, the worm wheel 725 and the rotating shaft 73 to rotate synchronously. Since the rotating block 72 is fixedly connected to the rotating shaft 73, it also drives the connecting block 717, the pad 1 724, the pad 2 727, the cylinder 729, the suction cup fixing plate 719, the vacuum suction cup 1 720, the induction switch 721, the vacuum suction cup 2 722, the vacuum suction cup 3 723 and the knitted glove 30 to rotate until they reach the set position; Figure 7 As shown, the telescopic position of the cylinder 729 is extended forward, and the suction cup fixing plate 719, vacuum suction cup 1 720, sensor switch 721, vacuum suction cup 2 722, vacuum suction cup 3 723 and the knitted glove move synchronously. The vacuum suction cup 1 720, vacuum suction cup 2 722 and vacuum suction cup 3 723 are used for ventilation and placement of the knitted glove. Figure 10 and Figure 1As shown, after each knitted glove 30 is placed on the glove receiving plate 81, the camera 13 takes a picture of the other side of the knitted glove 30 and transmits the picture to the terminal display 15. The terminal display 15 judges the knitting quality of the front and back sides of the knitted glove 30. If the knitting quality is good, the glove knitting machine continues to produce normally. If the knitting quality is bad, the glove knitting machine automatically stops and the relevant parts of the equipment need to be repaired. When the number of knitted gloves 30 on the glove receiving plate 81 reaches 24, the left and right drive devices and the upper and lower drive devices cooperate to operate, and the glove receiving plate 81 approaches the right side or right side of the left plate 817. When the glove stacking position 828 is on the left side of the side plate 814, the circular axis of the glove stacking position 828 is lower than the upper plane of the glove receiving plate 81. Then, during the movement to the left or right, the circular axis of the glove stacking position 828 enters the grid groove of the glove receiving plate 81 until it is completely directly below the knitted glove 30. Then, the upper and lower driving devices move downward, so that the knitted glove 30 is placed on the glove stacking position 828. Subsequently, the left and right driving devices cooperate with the upper and lower driving devices to return the glove receiving plate 81 to the glove receiving position; then the above actions are repeated until the six glove stacking positions 828 of the glove stacking device 825 are full of knitted gloves 30.

[0053] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
