[0002] In the production line, the flat grasping and vertical placing of plastic bottles is an action requirement. Flat grasping and vertical placing means grasping the bottles that were originally transmitted horizontally, and then flipping them 90° and standing them upright on the production line. This action is to better cooperate with the automatic labeling equipment. Flat grasping should ensure the stability of the bottles during the grasping process to avoid slipping or damage. And vertical placing is beneficial for the labeling equipment to accurately label specific positions on the bottle surface, so that the label can be accurately attached to the specified positions such as the front and side of the bottle. This placement method can improve the consistency and accuracy of the labeling position, and is more conducive to realizing automated and high-quality labeling operations compared with the method of randomly placing bottles.

This includes the coherence and coordination of each link from the transportation, grasping, placing to labeling of plastic bottles. If the flat grasping and vertical placing cannot be well achieved, it may lead to inconsistent bottle postures at the labeling station, affecting the normal operation of the labeling equipment and reducing production efficiency and labeling quality.

It is convenient to place the horizontally placed bottle vertically. In addition, the two buffer rods are convenient for displaying the posture accuracy of the suction cup and the grasped suction cup at the two extreme positions respectively. In terms of quick release, the spring buckle is used to achieve detachability. The spring buckle uses elastic tension to achieve contact and air tightness between the suction cup and the air circuit block.

It is convenient to replace suction cups of different specifications, and different suction cups are convenient to adapt to different bottles.

[0037] In some other embodiments of the present invention, the air circuit block 7 and the rotary cylinder 1 are connected to a fork-shaped member 3 on a common axis, and the relative positions of the buffer rod and the fork-shaped member 3 are fixed.

[0038] The beneficial effect of adopting the above technical solution is that the fork-shaped piece can provide a stable fixing space for the buffer rod.

[0042] The beneficial effect of adopting the above technical solution is that the first protruding arm and the second protruding arm extend the outer wall of the gas circuit block, which is convenient for contacting with the first hydraulic buffer and the second hydraulic buffer, and also increases the force arm, which is convenient for improving the limiting capacity.

[0043] In some other embodiments of the present utility model, a first bolt 13 is also penetratingly and movably assembled on the first convex arm 71, and one end of the first bolt 13 can contact the fixed plate 4 on the rotation path of the air circuit block 7.

[0044] The beneficial effects of adopting the above technical solution are as follows: By turning the first bolt, the protruding degree of the end of the first screw can be finely adjusted. The first bolt actually contacts the outer wall of the air circuit block, which is convenient for finely adjusting the specific rotation angle.

[0045] In some other embodiments of the present utility model, two groups of spring buckles are respectively arranged on both sides of the suction cup 9 or the air circuit block 7, and each group of spring buckles includes two parallel tension springs 14.

[0046] As Figure 6 shown, the spring buckle further includes a buckle plate 15 for realizing the pulling function of the tension spring 14. When the buckle plate 15 is pressed, it will swing, and then stretch the tension spring 14. There are a total of four tension springs 14, which are all parallel to each other, and the connection lines of their respective centroids

[0047] The beneficial effects of adopting the above technical solution are as follows: The number and arrangement of the tension springs are convenient for providing a uniform tightening force.

[0048] As Figure 2 、 Figure 4 shown, in some other embodiments of the present utility model, a transition block 8 is further arranged between the suction cup 9 and the air circuit block 7. The spring buckle connects the air circuit block 7 and the transition block 8. One end of the transition block 8 is movably assembled with a baffle 10 through a plurality of second bolts 12. The middle part of the baffle 10 has a hollow hole for the suction cup 9 to pass through.

[0049] The beneficial effects of adopting the above technical solution are as follows: The transition block is convenient for providing a layout position for some spring buckles. The baffle is to provide anti-collision protection for the periphery of the suction cup.

[0050] As Figure 2 shown, in some other embodiments of the present utility model, the transition block 8 and the air circuit block 7 respectively have mutually communicated second air cavities 81 and first air cavities 73. An elastic airtight ring 16 is assembled on the inner wall at the junction of the second air cavity 81 and the first air cavity 73.

[0055] The specific shape of the manipulator is not shown in the attached drawings.

[0056] The beneficial effects of adopting the above technical solution are as follows: After being matched with the manipulator, the suction cup can have a more flexible space movement ability.

[0057] The flipping structure can be used to achieve the flat grasping and vertical placing of plastic bottles for daily chemical products on the automated production line. The suction cup 8 has an active quick-change structure, which can enable a set of main body to be applicable to the grasping of products of multiple specifications. It can stably suck the circumferential surface on the side of the plastic bottle and perform flipping. Then it is vertically placed on the conveyor line body, so the suction position and flipping angle are required to be accurate. The suction cup at the initial position of the end is in a vertical state. After positioning and sucking the material, it is flipped by a flipping cylinder, and the flipping angle is controlled by a buffer rod to achieve the purpose of vertical placement.

[0058] For bottles of multiple specifications, different specifications of suction cups need to be used for matching, and it is extremely difficult to frequently disassemble the suction cup 9. The traditional assembly structure of the suction cup 9 is a thread, and frequent disassembly and assembly are also likely to damage the thread. Therefore, a quick-change structure is designed, and the quick-change structure is a spring-type buckle. In addition, an airtight ring 16 is used for the air circuit assembly of the middle air hole to ensure the airtightness of the gap at the docking part. The function of quickly switching the suction cups 9 at the end of different specifications is realized.

It cannot be used to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit essence of the present utility model should be covered within the protection scope of the present utility model.
