The principle of the invention is illustrated as follows:

before the device is used, a yarn barrel 1 is vertically inserted into a lifting support plate 24 in one side of a vertical lifting device 2, a pre-working state is carried out, after a signal that the tail yarn barrel is taken away and needs to be supplemented is obtained (namely, the yarn barrel 1 at the tail end of a horizontal conveying belt 34 is taken away), the lifting support plate 24 slides upwards along a lifting rack 23, the yarn barrel 1 is conveyed to a lifting discharge port 21, the yarn barrel 1 is pushed forwards to a horizontal feed port 31 by a clamping and holding clamp hand 42 to fall on the horizontal conveying belt 34, the operation is preferably finished by a yarn barrel transfer device 5, namely, the yarn barrel transfer device 5 recognizes that a new yarn barrel 1 exists at the horizontal feed port 31, then the yarn barrel transfer device 5 drives an inner clamping plate 534 and an outer clamping plate 535 to move inwards through a servo motor until the new yarn barrel is attached to the surface of the yarn barrel 1 and is grabbed, then the whole transfer clamping hand 53 travels a distance to the tail end of the horizontal conveying belt 34 to an initial yarn barrel position through a transfer sliding strip 52, and the transfer hand 53 puts down the yarn barrel 1 and finishes the process of yarn taking → the completion of the whole process of yarn taking-dropping.

In the process that the bobbin moves to the tail end along with the horizontal conveying belt 34, the inner blocking arm 37 and the outer blocking arm 38 arranged at the tail end of the horizontal conveying belt 34 are in a furled state to prevent the bobbin 1 from running out of the horizontal conveying belt 34 due to inertia, then, the bobbin 1 moves along with the horizontal conveying belt 34 until the detection light 39 is blocked by the bobbin 1, the yarn taking manipulator 891 takes the bobbin 1 away, after the bobbin 1 is taken away, the blocking of the detection light 39 disappears, and the horizontal conveying belt 34 resumes running again.

Therefore, the yarn carrying trolley 6 slides along the horizontal rail 61 to the position near the horizontal discharge port 32 at the end of the horizontal conveyor belt 34, after the yarn carrying trolley 6 reaches the yarn taking position, the lifting column 63 and the displacement compensation part 7 are matched with each other in a sliding way to control the yarn taking robot 891 to fall, so that the yarn taking clamping jaw 892 is inserted into the bobbin inner cavity 12, and then the yarn taking clamping jaw 892 is opened to take a new yarn bobbin 1. After grabbing, the lifting column 63 and the displacement compensation part 7 are in sliding fit with each other to drive the bobbin 1 to leave the horizontal conveying belt 34, the bobbin 1 can be found to be separated from the horizontal conveying belt 34 by a gravity monitoring method, after separation, the inner blocking arm 37 and the outer blocking arm 38 recover to be in a blocking state, and the horizontal conveying belt 34 recovers to run to convey the next bobbin 1 to a yarn taking position. Meanwhile, a yarn taking robot 891 for grabbing a new yarn barrel 1 moves to a position right above a yarn using station 133 needing yarn feeding along the yarn carrying trolley 6, at the moment, the sliding barrel 85 moves upwards along the lifting screw 8 to drive the inner oblique beam 86 and the outer oblique beam 87 to form a certain angle, so that the yarn taking clamping jaw 892 is opposite to the first barrel seat 153 or the second barrel seat 154 in the yarn using station 133, the yarn taking robot 891 is driven to fall onto the first barrel seat 153 or the second barrel seat 154 along an arc line through mutual sliding matching of the lifting straight column 63 and the displacement compensation part 7, the yarn taking clamping jaw 892 is closed immediately, the yarn barrel 1 loses support and falls onto the first barrel seat 153 or the second barrel seat 154, and the yarn feeding action is finished. Subsequently, the yarn taking machine 89 retracts the yarn taking robot 891 upwards, and at the same time, the lifting screw 8 and the sliding cylinder 85 slide relatively to drive the yarn taking robot 891 to return to the original vertical angle, and then the yarn carrying trolley 6 drives the yarn taking robot 891 to go to the original yarn supply area again to execute the next yarn feeding action, and so on.

In the invention, the outer hand included angle 871 formed by the outer oblique beam 87 and the hand fixing beam 88 is preferably a right angle.

In the present invention, the lower end of the left inclined side plate 71 and the lower end of the right inclined side plate 73 both preferably extend in a direction away from the lifting upright 63.

In the invention, the chain storage box 29 is preferably connected with a support column 292, the support column 292 is positioned between the first vertical column 232 and the second vertical column 233, the top end of the support column 292 is connected with the bottom of the lifting top plate 231, and the bottom end of the support column 292 is connected with the lifting bottom plate 234.
