[0040] Example 1

[0041] Ginseng Figures 2 to 7 As shown, this embodiment discloses a specific implementation of an M-bag reversing device (hereinafter referred to as "reversing device").

[0042] M bag reversing device, reference Figures 2 to 7As shown, it includes an M-bag loading component 1, an M-bag reversing component 2 and an M-bag lifting component 3; the M-bag loading component 1 includes an M-bag bin 11, a suction cup component 12 and an alignment component 13, the suction cup component 12 includes a suction cup 121 and a plurality of adsorption heads 122 installed on the suction cup 121, the suction cup component 12 places the M bags 4 in the M-bag bin 11 on the alignment component 13, the M-bag loading component 1 also includes a horizontal module 14 and a lifting module 15, the lifting module 15 moves horizontally along the horizontal module 14; the lifting module 15 includes a lifting slide rail 151, a lifting plate 152 and the suction cup component 12 installed on the lifting plate 152, the M-bag bin 11 is respectively arranged on both sides of the alignment component 13; the M-bag reversing component 2 includes a rotating shaft 21 and a first swing arm 22 and a second swing arm 23 arranged on the rotating shaft 21, the first swing arm 22 A first clamping finger 24 is arranged at the end, and a second clamping finger 25 is arranged at the end of the second swing arm 23. The rotation angle of the rotating shaft 21 is ±90°. The first clamping finger 24 and the second clamping finger 25 are used to clamp the M bag 4; the M bag lifting assembly 3 includes a lifting assembly 31 and an M bag clamping assembly 32 driven by the lifting assembly 31. The M bag clamping assembly 32 includes a horizontal plate 321, a first vertical plate 322 and a second vertical plate 323 arranged at both ends of the horizontal plate 321. A first rotating cylinder 324 and a first swing block 325 are arranged on one side of the first vertical plate 322. The first swing block 325 and the first vertical plate 322 cooperate to clamp one side of the M bag 4. A second rotating cylinder 326 and a second swing block 327 are arranged on one side of the second vertical plate 323. The second swing block 327 and the second vertical plate 323 cooperate to clamp the other side of the M bag 4.

[0043] Specifically, referring to Figure 1, referring to Figure 1(a), the cross-sections on both sides of the M bag are both M-shaped, the middle part of the M bag is two layers, and the two sides are four layers. Several stacked M bags are stacked and placed in an M bag silo 11. In order to make the topmost M bags in a relatively horizontal state, the M bag silo 11 includes a bottom plate 111, a boss 112 arranged on the bottom plate 111, and obliquely installed electrostatic rods 113 respectively arranged on both sides of the bottom plate 111. Guide wheels 114 are arranged at the ends of the electrostatic rods 113. The bosses 112 support the middle parts of several stacked M bags, so that the topmost M bags are in a horizontal state, thereby preventing the warping problem on both sides of several stacked M bags. In addition, the obliquely installed electrostatic rods 113 blow ion wind to several stacked M bags, with a large sweeping area, to prevent static electricity from being generated between the M bags. The guide wheels 114 play a guiding role when the M bags are sucked away, thereby preventing the electrostatic rods 113 from scratching the M bags.

[0044] See also Figures 2 to 4After the M bag 4 is sucked up by the suction cup assembly 12, due to the effect of gravity, the bag mouth of the M bag 4 will open and hang down, as shown in Figure 1(b). If the M bag hanging down cannot be lifted to a certain height, it will interfere with the M bag silo 11. In order to save space for the equipment, the suction cup 121 is a long rectangular strip, and the adsorption head 122 is distributed under the suction cup 121. The lifting plate 152 is provided with a first hinge point 1521 and a second hinge point 1522; the end of the suction cup 121 is installed at the first hinge point 1521, and at the second hinge point 1522 A swing cylinder 1523 is provided, and the telescopic end of the swing cylinder 1523 is installed on the middle part of the suction cup 121 through the third hinge point 1211; when the suction head 122 sucks the middle part of the M bag 4 and lifts it upward to the upper limit, the swing cylinder 1523 contracts and makes the suction cup 121 swing upward with the first hinge point 1521 as the center and be in an inclined state, so that the bag mouth of the M bag hanging downward avoids the M bag silo 11. The M bag avoids the M bag silo 11 without being lifted to a higher position, and the equipment is more compact and can achieve more efficient delivery of the M bags to the alignment component 13.

[0045] See also Figure 2 and Figure 5The purpose of the alignment component 13 is to accurately align the M bags 4 placed in the alignment component 13 so that the M bag reversing component 2 can accurately take out the M bags 4. The alignment assembly 13 includes a positioning support plate 131 and a first alignment plate 132, a second alignment plate 133, a third alignment plate 134 and a fourth alignment plate 135 arranged around the positioning support plate 131; when the horizontal module 14 drives the lifting module 15 to a predetermined position, the lifting plate 132 drives the suction cup 121 to descend, and the swing cylinder 1523 extends and makes the suction cup 121 in a horizontal state, so that the M bag 4 is released in a horizontal state on the surface of the positioning support plate 131; the first alignment plate 132 is driven by the first telescopic cylinder 1321, and the second alignment plate 133 is driven by the second telescopic cylinder 1331. The first alignment plate 132 and the second alignment plate 133 enable the two sides of the M bag 4 to be aligned, and the third alignment plate 134 is driven by the third telescopic cylinder 1341; the fourth alignment plate 135 is driven by the fourth telescopic cylinder 1351 and the lifting cylinder 1352, the fourth telescopic cylinder 1351 drives the lifting cylinder 1352 to move horizontally, and drives the fourth alignment plate 135 to move horizontally, and the lifting cylinder 1352 drives the fourth alignment plate 135 to move up and down; when the M bag 4 is released on the surface of the positioning tray 131 in a horizontal state, the first alignment plate 132 and the second alignment plate 133 align the two sides of the M bag, and the third alignment plate 134 and the fourth alignment plate 135 align the two ends of the M bag. The positioning tray 131 is also provided with a plurality of negative pressure suction heads. After the alignment is completed, the M bag 4 is adsorbed and fixed in position by the negative pressure suction heads. After the M bag 4 is fixed, the lifting cylinder 1352 drives the fourth alignment plate 135 to descend to the bottom of the positioning tray 131, so that the positioning tray 131 forms an outlet for the M bag 4, which is convenient for the M bag reversing component 2 to take away the used M bag.

[0046] See also Figure 2 , Figure 3 and Figure 6 The working principle of the M bag reversing assembly 2 is as follows: the rotating shaft 21 is driven by the motor 26, and when the rotating shaft 21 rotates downward by 90° (see Figure 2 ), the first swing arm 22 and the second swing arm 23 swing downward 90°, and the first clamping finger 24 and the second clamping finger 25 clamp the M bag 4 from the alignment component 13; when the rotating shaft 21 swings back 90°, the first swing arm 22 and the second swing arm 23 swing back 90°, and the first clamping finger 24 and the second clamping finger 25 change the clamped M bag 4 from a horizontal state to a vertical state, specifically referring to the M bag 4 clamped by the first clamping finger 24 and the second clamping finger 25 as shown in 2.
