[0002] In the wet wipes production process, the palletizing process is crucial. Its purpose is to stack the produced wet wipes products in an orderly manner for subsequent storage and transportation. Traditional wet wipes palletizing mostly relies on robotic arms.

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0032] Embodiment: A palletizing device for wet wipes transfer, such as Figure 1-Figure 13 As shown, the machine platform 1 includes a conveying seat 2, a third motor 15, an L-shaped frame 16, a cylinder 17, a suction cup frame 18, a stacking plate 19, an electronic scale 20, a storage plate 21, an electric guide rail 22 and a discharging rack 23. The conveying seat 2 is installed on the machine platform 1, and the first conveyor belt and the second conveyor belt are installed on the conveying seat 2 in a front-to-back phase sequence. The machine platform 1 is provided with a fine-tuning mechanism near the end of the second conveyor belt, and two stacking plates 19 are installed on the fine-tuning mechanism. The third motor 15 is installed between the two stacking plates 19. The output shaft of the third motor 15 is fixedly connected with the L-shaped frame 16, and the cylinders 17 are installed at both ends of the L-shaped frame 16. The suction cup frame 18 is installed on the telescopic shaft of the cylinder 17. An electronic scale 20 is provided in the stacking plate 19, and a storage plate 21 is provided at the top of the electronic scale 20. An electric guide rail 22 is installed on the storage plate 21, and a discharging rack 23 is installed on the electric guide rail 22.

[0033] like Figure 1-Figure 3 As shown, a first motor 5 and an electric screw 6 are installed on the outer side of the conveying seat 2, a first movable seat 601 is threadedly installed on the electric screw 6, a movable conveyor belt 4 is installed on the first movable seat 601, and a fixed conveyor belt 3 is installed on the inner side of the conveying seat 2. The movable conveyor belt 4 and the fixed conveyor belt 3 are driven to rotate by the first motor 5. The electric screw 6 is started, and the first movable seat 601 moves on the electric screw 6. Since the movable conveyor belt 4 is installed on the first movable seat 601 and the fixed conveyor belt 3 is installed on the conveying seat 2, the moving distance of the first movable seat 601 on the electric screw 6 can be adjusted to limit the wet wipes of different widths.

[0034] like Figure 4-Figure 5As shown, electric push rods 9 are installed on the outer side of the conveying seat 2 near the first conveyor belt and the second conveyor belt, and a detection table 11 is installed near the electric push rod 9 of the conveying seat 2. A slide groove 1101 is opened on the top of the detection table 11, and the visual detector 12 is slidably connected to the detection table 11 through the slide groove 1101. The conveying seat 2 and the first movable seat 601 are slidably connected to the waste tray 10 near the electric push rod 9. The device can remove unqualified products in time by visually inspecting the outer packaging of wet wipes, combined with the electric push rod 9 and the waste tray 10, and effectively ensure product quality.

[0035] like Figure 6 As shown, a lampshade 13 is installed on the visual detector 12, and the lampshade 13 has 4 rotatable lampshade 13 leaves, and each lampshade 13 leaf is equipped with an LED lamp 14. The angle of the lampshade 13 leaves can be adjusted in advance to focus the illumination on the wet wipes.

[0036] like Figure 2-Figure 3 As shown, a second motor 7 is installed on the outer side of the conveying seat 2 near the first conveyor belt and the second conveyor belt, and two flip frames 8 are installed on the output shaft of the second motor 7. The flip frames 8 are located between the fixed conveyor belt 3 and the movable conveyor belt 4. The flip frames 8 are in the shape of a flower with a total of 8 petals. There are clamping grooves for accommodating wet wipes between adjacent petals. The wet wipes can be turned over by the flip frames 8 to achieve the effect of detecting both sides of the wet wipes.

[0037] like Figure 10-11 As shown, a bidirectional screw 24 perpendicular to the electric guide rail 22 is installed on the stacking plate 19, and two limit frames 25 are threadedly installed on the bidirectional screw 24. By rotating the knob of the bidirectional screw 24, the distance between the two limit frames 25 can be adjusted to accommodate the neat stacking of wet wipes of different widths.

[0038] like Figure 1 and Figure 8 As shown, a screw table 26 is installed at the end of the machine 1 near the second conveyor belt, a second movable seat 27 is installed on the screw table 26, two stacking plates 19 are installed on the second movable seat 27, and a third motor 15 is installed between the two stacking plates 19. After adjusting the distance between the movable conveyor belt 4 and the fixed conveyor belt 3, in order to ensure that the suction cup frame 18 is aligned directly above the second conveyor belt, the knob of the screw table 26 can be rotated to move the second movable seat 27 on the screw table 26, and then the third motor 15 is adjusted to be located between the movable conveyor belt 4 and the fixed conveyor belt 3 to achieve precise suction.

[0039] like Figure 12-13As shown, a connecting frame 28 is installed on the second movable seat 27, and the connecting frame 28 is fixedly connected to the visual detector 12 near the two detection platforms 11. The connecting frame 28 moves with the second movable seat 27, driving the visual detector 12 to move in the slide slot 1101 of the detection platform 11, so that the visual detector 12 is aligned with the middle of the movable conveyor belt 4 and the fixed conveyor belt 3.

[0040] The wet wipes are transferred to the first conveyor belt, which is intermittently driven by the first motor 5. The wet wipes are intermittently moved to the bottom of the visual detector 12 at the first conveyor belt. The visual detector 12 takes pictures of the upper surface of the wet wipes and performs visual comparison through a computer. If problems such as incomplete packaging printing are detected, the electric push rod 9 is started, and its telescopic rod pushes the wet wipes out of the first conveyor belt and falls into the collection tank at the bottom of the device through the waste tray 10.

[0041] The wet wipes that have passed the inspection continue to move to the turning frame 8, and the second motor 7 also rotates intermittently to drive the two turning frames 8 to rotate. Through the coordinated cooperation of the first motor 5 and the second motor 7, the wet wipes enter the accommodating grooves of the turning frame 8 one by one, and the turning frame 8 rotates to turn the wet wipes over and drop them onto the second conveyor belt. After being transported by the second conveyor belt, the wet wipes intermittently move to the bottom of the visual detector 12 at the second conveyor belt for lower surface inspection. The inspection process is the same as that of the upper surface inspection.

[0042] Finally, the qualified wet wipes arrive near the third motor 15. The cylinder 17 on the output shaft of the third motor 15, which is close to one end of the second conveyor belt, extends the telescopic rod, so that the suction cup frame 18 contacts the wet wipes, sucks the wet wipes by vacuuming, and the cylinder 17 retracts the telescopic rod. The third motor 15 rotates 90°, so that the suction cup frame 18 with the wet wipes is located above the stacking plate 19. The cylinder 17 extends the telescopic rod again, and the suction cup frame 18 stops vacuuming, and the wet wipes are placed on the stacking plate 19. The cylinder 17 retracts the telescopic rod. At this time, the suction cup frame 18 at the other end of the L-shaped rod is located above the second conveyor belt, repeating the above action to suck new wet wipes, and the third motor 15 rotates 90° in the opposite direction to put the wet wipes into the stacking plate 19 on the other side. This cycle is repeated to achieve efficient stacking.

[0043] The stacked wet wipes are located between the two limit racks 25. By rotating the knob of the bidirectional screw 24, the distance between the two limit racks 25 can be adjusted to accommodate the neat stacking of wet wipes of different widths. When the weight of the wet wipes stack reaches the preset value of the electronic scale 20, the electric guide rail 22 in the stacking tray 19 is started, and the discharge rack 23 moves on the electric guide rail 22 to push the stacked wet wipes to the conveyor belt outside the stacking tray 19 to enter the next process.
