[0037] Please refer to Figures 1 to 8 together with the following for a description of the self-standing bag upper cover assembly 10 and the self-standing bag filling and capping device provided by the embodiments of the present utility model.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 7 The embodiments of the present utility model provide a self-standing bag upper cover assembly 10, including a cap feeding chute 11 and an upper cover mechanism 12. The cap feeding chute 11 is used for the cap body 14 to slide. The upper cover mechanism 12 includes a cap picking unit 121, a first lateral translation unit 122, and a lifting unit 123. The cap picking unit 121 is arranged at the conveying end of the cap feeding chute 11. The first lateral translation unit 122 is used to drive the cap picking unit 121 to move horizontally, so that the cap picking unit 121 moves above the cap feeding chute 11 and the self-standing bag. The lifting unit 123 is used to drive the first lateral translation unit 122 to move vertically.

[0039] Compared with the prior art, the beneficial effects of the self-standing bag upper cover assembly 10 provided by the embodiments of the present utility model are as follows:

[0040] The self-standing bag upper cover assembly 10 provided by the embodiments of the present utility model includes a cap feeding chute 11 and an upper cover mechanism 12. The cap body 14 to be installed can slide along the cap feeding chute 11 to the picking position of the cap picking unit 121. When the upper cover mechanism 12 works, first, the lifting unit 123 controls the cap picking unit 121 to descend, so that the cap picking unit 121 obtains the cap body 14. Then, the first lateral translation unit 122 drives the cap picking unit 121 and the cap body 14 to move horizontally together, so that the cap body 14 is located above the bag body 21 of the self-standing bag. Finally, the lifting unit 123 controls the cap picking unit 121 to descend, and installs the cap body 14 at the nozzle of the bag body 21 of the self-standing bag, completing the automatic capping operation. After capping, the first lateral translation unit 122 and the lifting unit 123 drive the cap picking unit 121 to reset, waiting for the installation operation of the next cap body 14. In the embodiments of the present utility model, the cap feeding chute 11, the cap picking unit 121, the first lateral translation unit 122, and the lifting unit 123 work together to complete the automatic capping operation of the cap body 14, saving labor and having a high degree of automation and mechanization.

[0041] In the embodiments of the present utility model, the self-standing bag upper cover assembly 10 includes a cap feeding chute 11 and an upper cover mechanism 12. The cap feeding chute 11 is used for the cap body 14 to slide. Multiple cap bodies 14 can be neatly arranged along the cap feeding chute 11, so that the cap picking unit 121 can pick up the cap bodies 14 one by one and install them on the bag body 21 of the self-standing bag. The cap feeding chute 11 can be made of stainless steel, aluminum alloy or other materials, with small sliding resistance of the cap body 14 and not easy to get stuck.

[0042] Since the outer shape of the cover body 14 is cylindrical, thicker at the top and thinner at the bottom. Adapted to the shape of the cover body 14, the cross-sectional shape of the cover feeding slideway 11 can be designed as Figure 1 the T shape shown. The upper half of the cover body 14 is accommodated in the cover feeding slideway 11, and the lower half of the cover body 14 extends out of the hollow at the bottom of the cover feeding slideway 11, so that the cover body 14 will not fall out of the cover feeding slideway 11. Of course, the cover feeding slideway 11 can also be of other shapes as long as it can meet the use requirements.

[0043] The upper cover mechanism 12 includes a cover taking unit 121, a first transverse movement unit 122 and a lifting unit 123. The cover taking unit 121 can be a tooling fixture such as a vacuum suction nozzle or a manipulator that can acquire and release the cover body 14. After the cover taking unit 121 successfully acquires the cover body 14, the first transverse movement unit 122 is used to drive the cover taking unit 121 to move above the self-standing bag body 21, and the lifting unit 123 is used to insert the lower part of the cover body 14 into the nozzle of the self-standing bag body 21 to complete the installation of the cover body 14.

[0044] The first transverse movement unit 122, the lifting unit 123, and the power devices such as the second transverse movement unit 132, the first driving member 521, and the second driving member 522 that appear below can be cylinders, electric telescopic rods, telescopic motors, etc., as long as they can drive the corresponding components to complete linear reciprocating movement.

[0045] Please refer to Figure 2 and Figure 7 , in some possible embodiments, a hole 141 is formed in the top of the cover body 14. After the working end of the cover taking unit 121 is inserted downward into the hole 141, a frictional force can be generated with the inner wall of the hole 141, and the frictional force enables the cover body 14 to be attached to the working end of the cover taking unit 121 by overcoming its own gravity; the self-standing bag upper cover assembly 10 further includes a cover pressing mechanism 13, and the cover pressing mechanism 13 includes a cover pressing unit and a second transverse movement unit 132. When the cover pressing unit is located above the cover body 14, it can interfere with the vertical movement of the cover body 14; the second transverse movement unit 132 is used to drive the cover pressing unit to move horizontally so that the cover pressing unit moves above the cover body 14 or moves away from above the cover body 14.

[0046] In this embodiment, the cover taking unit 121 is as shown in Figure 2For the cylindrical part shown, the cap-taking unit 121 can be inserted downward into the hole 141 of the cap body 14. After the cap-taking unit 121 is inserted, the cap body 14 can be attached to the cap-taking unit 121 by friction, enabling the cap-taking unit 121 to drive the cap body 14 to move. When the cap body 14 is inserted into the self-standing bag body 21, the capping unit limits the position of the cap body 14. In this way, when the lifting unit 123 drives the cap-taking unit 121 to rise, the cap body 14 will not move together with the cap-taking unit 121. There is no restriction on the material of the cap-taking unit 121. For example, the cap-taking unit 121 can be made of materials such as rubber.

[0047] Please refer to Figure 1 、 Figure 2 and Figure 7 As shown in, the capping unit is the capping plate 131. An opening 1311 is provided on the side of the capping plate 131 adjacent to the cap-taking unit 121. The size of the opening 1311 is larger than the diameter of the cap-taking unit 121 and smaller than the diameter of the cap body 14. With this setting, when the capping plate 131 is located above the cap body 14, the opening 1311 can allow the working end of the cap-taking unit 121 to pass through and can form a stop for the cap body 14 below.

[0048] Please refer to Figure 1 and Figure 2 As shown in, in some possible embodiments, the cap feeding chute 11 includes a first sliding cap groove 111 and a second sliding cap groove 112 that are connected end to end in sequence. The first sliding cap groove 111 is inclined in the vertical direction, the second sliding cap groove 112 is horizontally arranged, and a stop portion 113 is provided at the end outlet. The cap-taking unit 121 is movably arranged above the end outlet of the second sliding cap groove 112.

[0049] In this embodiment, the first sliding cap groove 111 is designed to be inclined, so that the cap body 14 can automatically fall under the action of gravity, making the transportation more convenient. A stop portion 113 is provided at the end of the second sliding cap groove 112. The stop portion 113 can be a plate or block structure, which can block and position the cap body 14. To avoid the cap body 14 from sliding and jamming, the connecting position between the first sliding cap groove 111 and the second sliding cap groove 112 should be designed as a transitional arc.
