[0036] Specifically, the limiting rib device further includes a first self-reset button 63 and a second self-reset button 64 .

[0037] The working principle of the position limiting side guard device: manually press the first self-reset button 63, the fourth motor 59 rotates, drives the gear 60 to rotate, the gear 60 drives the two racks 61 to move relative to each other, and the two gears 60 drive the two sliders 56 and the two baffles 54 to move outward respectively. When they move to the appropriate position, release the first self-reset button 63, and the spacing between the two baffles 54 can be adjusted to adapt to packaging trays of different sizes. If the first reset button 1 is continuously pressed, the slider 56 continues to move outward, and when the outer proximity switch senses the slider 56, the fourth motor 59 automatically stops to achieve the collision protection function. Press the second self-reset button 64, the fourth motor 59 rotates in the opposite direction, drives the gear 60 to reverse, and the gear 60 drives the two racks 61 to move toward each other, and then drives the two sliders 56 to move toward each other. After moving to the appropriate position, release the second self-reset button 64, and the spacing between the two baffles 54 can be adjusted. When the second self-reset button 64 is continuously pressed, the slider 56 continues to move toward the center. When the inner limit switch 62 senses the slider 56, the fourth motor 59 automatically stops to achieve the function of avoiding collision protection. The above function adjusts the distance between the two baffles 54 to adapt to packaging trays of different lengths. After the distance between the two baffles 54 is adjusted to be larger than the size of the packaging tray, the packaging tray is manually placed on the lifting platform 13, and the first self-reset button 63 and the second self-reset button 64 are pressed to adjust the two blocks to the appropriate position, which is suitable for positioning and adjusting packaging trays of different sizes.

[0038] Specifically, the first motor 7, the second motor 16, the first cylinder 24, the second cylinder 37, the vacuum suction cup 38, the third motor 41, the first induction switch 34, the second induction switch 33, the third induction switch 35, the fourth induction switch 2, the proximity switch 26, the fifth induction switch 30, and the sixth induction switch 31 are each connected to a controller through their input and output ends, and a control panel is provided on the side of the frame 1, and a start button 3 and a proximity switch 26 are provided on the control panel.

[0039] The present invention is used in conjunction with a robot.

[0040] The working principle of this embodiment:

[0041] Loading: manually place the packaging tray 50 on the lifting platform 13, the stacking height is below the fourth sensing switch 2, press the start button 3, the output end of the first motor 7 drives the first pulley 8 to rotate, the first pulley 8 drives the first belt 11 to move, the first belt 11 drives the lifting platform 13 to rise for feeding, when the proximity switch 26 senses the lifting platform 13, the first motor 7 stops, and the lifting platform 13 stops.

[0042] Material taking: The piston rods of the first cylinder 24 and the second cylinder 37 descend simultaneously, the suction cups of the first cylinder 24 and the second cylinder 37 simultaneously suck the packaging tray 50, and the piston rods of the first cylinder 24 and the second cylinder 37 rise. Then the first cylinder 24 and the second cylinder 37 are lifted and lowered three times in turn, so as to shake and separate the packaging tray 50 up and down, and the lifting and lowering shaking amplitude is very small.

[0043] The output end of the second motor 16 drives the turntable 17 to rotate through the rotating shaft 18, so that the first rod end joint bearing 19 drives the first cylinder 24 to move along the guide rod 22 through the first movable plate 21. At the same time, the second rod end joint bearing 20 drives the second cylinder 37 to move along the guide rod 22 through the second movable plate 25. The moving direction of the first cylinder 24 is opposite to or opposite to the moving direction of the second cylinder 37, so that it can be compatible with packaging trays 50 of various specifications and styles. It only needs to select the corresponding program for automatic adjustment without manual adjustment.

[0044] The packaging trays 50 that are adhered to each other are separated by the rotation and contraction of the second motor 16 and the lifting and lowering joint action of the first cylinder 24 and the second cylinder 37.

[0045] Transverse movement: The output end of the third motor 41 drives the third pulley 42 to rotate, and the third pulley 42 drives the second belt 44 to move horizontally. The second belt 44 drives the movable seat 14 to move left along the length direction of the frame 1 through the second connecting member 45, so that the entire transverse movement device 4 moves left to the top of the fixed frame 5.

[0046] Unloading: The first cylinder 24 and the second cylinder 37 descend simultaneously, the vacuum suction cup 38 is released, and the packaging tray 50 is placed on the fixed frame 5.

[0047] Lateral movement reset: The output end of the third motor 41 drives the lateral movement device 4 to move to the top of the lifting platform 13 for the next round of action. At this time, the robot puts the bottle into the packaging tray 50 to complete the robot palletizing packaging.

[0048] The silo platform descends: when the lifting platform 13 rises to the highest point and the proximity switch 26 senses the lifting platform 13, it will no longer rise, and when the fourth sensing switch 2 senses that there is no packaging tray 50 on the lifting platform 13, it means that the packaging tray 50 has been used up and the controller alarm is used to remind the staff, and the output end of the first motor 7 drives the first pulley 8 to rotate in the opposite direction, the first pulley 8 drives the first belt 11 to rotate, and the first belt 11 drives the lifting platform 13 to descend to the initial position, and the packaging tray 50 continues to be put in manually. After the packaging tray 50 is put in, press the reset button 27 to continue to automatically complete the operation.

[0049] The packaging tray separator of the present invention realizes automatic separation of packaging trays 50, feeds one sheet at a time, automatically loads and takes out materials, takes out materials when sensing the presence of materials, and puts them on the fixed frame 5 for the robot to stack and package; solves the problem of sticking of packaging trays 50, and separates the packaging trays 50 by shaking; has a material shortage alarm function, when there is a shortage of materials, the lifting platform 13 automatically descends, and an alarm prompts manual insertion of a whole stack of packaging trays 50; reduces manual labor intensity and workload, and improves production efficiency; increases the feeding stroke, and the size range of the packaging tray 50 is adjustable, and is compatible with a variety of packaging trays 50 of the same size, and there is no need to replace the fixed frame 5 according to the packaging tray 50.

[0050] Manual workers only need to put the entire stack of packaging trays 50 into the silo platform, and the packaging separator will automatically separate the packaging trays 50, effectively cooperating with the robot to pick up and place materials, and put the packaging trays 50 filled with products into turnover boxes, saving labor. When the equipment is running automatically, workers can operate other machines or do some related preparatory work, reducing irrelevant waiting time and improving production efficiency.
