[0002] As people's material and cultural lives continue to improve, their demands for daily life are increasing, leading to a greater need for body care and skincare products, and consequently, a greater demand for corresponding packaging bottles. In existing technologies, after packaging bottles are produced, they need to be printed with text and images using a printing press. During the printing process, operators manually load the bottles onto the printing press's conveyor belt. To meet production rhythms, this manual loading action is constantly required, consuming a significant amount of manpower and resulting in high labor intensity. Utility Model Content

[0020] Furthermore, the wave-shaped feeding conveyor belt 1, the upright packaging bottle conveyor belt 4, and the horizontal packaging bottle conveyor belt 10 each include a servo motor and a conveyor belt, and the output shaft of the servo motor is connected to the conveyor belt through a transmission mechanism.

[0025] Specifically, the specific structures and principles of components such as the conveyor belt, six-axis robot 3, inductive switch, slide rail cylinder 7, PPU robot 9, printing machine loading robot, controller, alarm, rotary drive mechanism, adsorption device, photoelectric sensor, and lifting drive mechanism 17, as well as other aspects not described in detail, all adopt known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here. For example, the PPU robot 9 is a parallel pick and place unit, which also includes a cam drive mechanism 22 for driving the second packaging bottle adsorption device 15 to move rapidly laterally between the upright packaging bottle conveyor belt 4 and the horizontal packaging bottle conveyor belt 10.

[0026] The working principle of this embodiment:

[0027] The operator manually places four sets of corrugated trays loaded with flat-lying packaging bottles onto the corrugated tray feeding conveyor belt 1, from left to right. Each set consists of 6-7 stacked corrugated trays. The servo motor of the corrugated tray feeding conveyor belt 1 drives the conveyor belt to transport one set of corrugated trays to the corrugated tray induction switch 2. When the corrugated tray induction switch 2 detects the corrugated tray, the corrugated tray feeding conveyor belt 1 stops conveying under the control of the controller. The six-axis robot 3 uses the first packaging bottle adsorption device 14 in conjunction with the vacuum generator to adsorb a row of packaging bottles on the corrugated tray using the vacuum adsorption function provided by the air circuit. Then, the first packaging bottle rotation drive mechanism 12 of the six-axis robot drives the flat-lying packaging bottles to rotate into an upright position. The six-axis robot then carries the packaging bottles past the counting induction switch 5 at the left end of the upright packaging bottle conveyor belt 4 and places them onto the upright packaging bottle conveyor belt 4. The counting induction switch 5 detects and confirms whether the quantity of packaging bottles is correct. If the quantity is incorrect, an alarm sounds, reminding the operator to check if there are any packaging bottles on the corrugated tray that have not been adsorbed by the six-axis robot. If any are missed, they are manually removed from the corrugated tray.

[0028] Next, the upright bottle conveyor belt 4 starts, conveying the upright bottles to the right. When the upright bottle sensor switch 6 detects a bottle, the piston rod of the slide rail cylinder 7 drives the stop block 8 to extend to the left. At the same time, the upright bottle conveyor belt 4 stops conveying, and the stop block 8 blocks the bottle, preventing it from moving to the right. The stop block 8 blocks only one bottle at a time. Then, the PPU robot arm 9 drives the second bottle adsorption device 15 to move to one side of the upright bottle conveyor belt 4 to adsorb the bottle blocked by the stop block 8. Then the PPU machine... The robotic arm 9 drives the second packaging bottle adsorption device 15 onto the flat packaging bottle conveyor belt 10. At the same time, the second packaging bottle rotation drive mechanism 13 of the PPU robotic arm 9 drives the upright packaging bottle to rotate to a flat position. Then, the packaging bottle is placed on the flat packaging bottle conveyor belt 10. The flat packaging bottle conveyor belt 10 transports the packaging bottle to the flat packaging bottle induction switch 11 at the left end. When the flat packaging bottle induction switch 11 senses the packaging bottle, the printing machine loading robotic arm grabs the packaging bottle and places it onto the loading conveyor belt in the printing machine, completing the loading.

[0029] After the six-axis robot 3 has completely absorbed all the bottles on a wave tray, the tray, which was originally full of bottles, is now empty. The tray-retrieving device 16 then activates, and the lifting drive mechanism 17 drives the wave tray suction device 20 to rise. The second tray-retrieving rotation drive mechanism 19 drives the wave tray suction device 20 to rotate 90° above the wave tray. The rotation angle can be controlled by a photoelectric sensor. Next, the lifting drive mechanism 17 drives the wave tray suction device 20 downwards to absorb the wave tray. Then, the lifting drive mechanism 17 drives the wave tray suction device 20 upwards to the top. The first tray-retrieving rotation drive mechanism 18 drives the wave tray suction device 20 to rotate 90° above the turnover box 21. The lifting drive mechanism 17 then drives the wave tray suction device 20 downwards, and the wave tray suction device 20 stops absorbing, allowing the wave tray to fall into the turnover box 21. After the operation is complete, the device is reset, and the operation will resume after the six-axis robot 3 has picked up a tray of bottles. Once the turnover box 21 is full, the turnover box 21 filled with the corrugated plate is removed manually and replaced with an empty turnover box 21.

[0030] This invention uses a six-axis robotic arm 3 to sequentially pick up packaging bottles from a corrugated tray, placing them upright on an upright packaging bottle conveyor belt 4 and transporting them to a PPU robotic arm 9. The PPU robotic arm 9 picks up the bottles and rotates them to a horizontal position, ensuring the length of the bottles is parallel to the conveying direction, before placing them on a horizontal packaging bottle conveyor belt 10. This meets the feeding requirements of the printing machine. Finally, the printing machine robotic arm picks up the bottles and places them onto the printing machine's feeding conveyor belt. During automatic operation, the operator can operate other machines, periodically collect empty trays, and replenish full trays of packaging bottles, avoiding fatigue from prolonged monotonous manual work and reducing labor intensity.
