Problems solved by technology

[0003] In the capping device, even if the shape and size of the cap and the container are of the same type, it will change due to the conditions during molding or storage, and defects will occur in the cap engaging part due to poor thread engagement between the cap and the container, etc. Leakage and other failures may occur, hindering productivity
In capping devices using caps of various types and shapes, such failures are likely to be more frequent

Embodiment 1

[0120] (Example 1)( Figure 1 to Figure 11 )

[0121] The capping device 10 is a device for capping by screwing the cap 1 into the container 2 . Containers 2 are supplied via a container supply conveyor 20 .

[0122] The capping device 10 is provided with an elevating platform 33 on the elevating guide device 32 of the base 31, and the elevating platform 33 is provided with a formal fastening device 35 and a temporary fastening device 70 so as to be integrated with the formal fastening device 35. The way is attached to the formal fastening device 35. Specifically, the main fastening device 35 and the temporary fastening device 70 are arranged such that the rotation centers of the rotary caps coincide, that is, the capping positions are coaxial. The temporary fastening device 70 temporarily fastens the cap 1 relative to the container 2 with a small torque (the maximum torque of the temporary fastening device 70 does not destroy the thread), and the formal fastening device 35...

Embodiment 2

[0148] (Example 2)( Figure 12 )

[0149] The capping device 100 of Embodiment 2 is provided with a rotating motor 102 for temporary fastening / formal fastening on the lifting platform 101, and a telescopic pneumatic cylinder 104 is installed on the upper middle part of the rotating shaft 103 of the rotating motor 102. The lower middle part of the rotating shaft 103 is provided with an opening and closing device 105, and the opening and closing device 105 is provided with a pair of left and right opening and closing chucks 106, and at the same time, a free joint 107 is provided at the lower end of the rotating shaft 103 as a cover holder. Vacuum pad 108A of mechanism 108 . A rotary air joint 109 provided on the rotary shaft 103 supplies air pressure to the cylinder 104 and the opening and closing device 105 . An air pressure supply pipe (not shown) or a vacuum pipe (not shown) is connected to the rotary air pressure joint 109 so that twisting of the air pressure supply pipe o...

Embodiment 3

[0153] (Example 3)( Figure 13 to Figure 16 )

[0154] The capping device 200 of embodiment 3, such as Figure 13 , Figure 14 As shown, the temporary fastening device 210 and the final fastening device 220 are arranged side by side at respective capping positions (temporary fastening position and final fastening position) adjacent to each other along the container supply conveyor belt 201 .

[0155] Temporary fastening means 210, such as Figure 15 As shown, a linear elevator 213 is provided in front of an elevator table 212 that can be lifted and lowered on a base 211, a hollow shaft motor 215 is provided on an elevator table 214 of the elevator 213, and a cover is provided on a rotating shaft 216 of the motor 215. A bellows vacuum pad 217A that holds the mechanism (cap) 217 ​​. The vacuum pad 217A is vacuum-connected by the rotary joint 218 at the upper end of the rotary shaft 216, and holds the top surface of the lid 1 by vacuum suction. The lid holding mechanism 217 ...

Abstract

The invention provides a capping device (10) having a temporary tightening device (70) for temporarily tightening a cap (1) to a container (2) and also having a final tightening device (35) for finally tightening the cap. While holding the cap (1), the temporary tightening device (70) allows the center axis of the cap (1) to rock about the center axis of the container (2).

Description

technical field [0001] The invention relates to a capping method and device. Background technique [0002] In screw fastening devices, especially capping devices, even if the shape and size of the cap and the container are of the same type, it will change due to the conditions during molding or storage. If there is a defect in the meshing part of the cover due to poor meshing, etc., there may be failures such as leakage. In a capping apparatus using caps of various types and shapes, such failures may occur more frequently, thereby hindering productivity. [0003] In the capping device, even if the shape and size of the cap and the container are of the same type, it will change due to the conditions during molding or storage, and defects will occur in the cap engaging part due to poor thread engagement between the cap and the container, etc. Failures such as leaks may occur, hindering productivity. In a capping device using caps of various types and shapes, such failures m...
