We proposed a method for double seaming using the automatic can lid seaming device disclosed in No. 238. In this method, as shown in FIG. 6, a can body 2 with a can M1 fitted thereon is clamped and held between a rotatably supported chuck 4 and a lifter plate 5. A first tightening roll 8 is driven and rotated around the circumference A11a of the can lid 1 of the body 3 via an intermediate gear 6 and a tightening roll drive gear 7 that meshes with the intermediate gear 6 from an m-shift device (not shown). The first seaming groove 8a is approached from the side by operating the lever mechanism 9 and brought into pressure contact to form the first seaming part 1b as shown in FIG. from the first winding part 1b to the first
While removing (retreating) the seaming groove 8a, one lever mechanism 10 is operated to drive and rotate the seaming roll via the intermediate gear 11 and the seaming roll driving gear 12 in the same manner as the first seaming roll. The second seaming groove 13a of the second seaming roll 13 is brought close to the periphery of the first seaming portion 1b, and the second seaming groove 13a is brought into pressure contact with the first seaming portion 1b to form a second seaming portion 1c as shown in FIG. It is something.

連続して、スムーズな流れで行なえるようにしている。In this seaming method, as the speed of seaming work increases, a chuck and a lifter plate that clamp and hold the can body from above and below, and a first lifter plate arranged around the chuck and lifter plate that rotates around the can body are used. A set of a seaming roll and a second seaming roll are arranged on a circular orbit, and while moving,
The first seaming roll and the second seaming roll are sequentially brought closer to the can body to form a double seaming part, so that the can body can flow continuously and smoothly.

The first seam tightening groove 8a and the second seam tightening groove 13a of the second seam tightening roll 13 are sequentially brought close to the can lid of the can body and brought into pressure contact,
Since the first seaming part and the second seaming part are formed by retreating, in order to seam the can body 3 while advancing it,
As the can body 3 advances, the first and second seaming rolls 8 and 13 must also advance, and the first and second seaming rolls and the drive devices for these seaming rolls are also one set. (The chuck, the lifter plate, the first and second seaming rolls, and the driving device for these seaming rolls are one set.) are arranged in a suitable number on a circular track, and the machine moves along the circular track with the can body. However, since the area occupied by one set of equipment that moves together with one can body is large, the gap between can bodies is wide in this configuration, and the seaming efficiency is still poor. The problem is that the configuration becomes complicated.

It is an object of the present invention to provide a can lid seaming method that can improve seaming efficiency and simplify the configuration of a seaming device.

There is no need to provide a driving device for the tightening rolls, and instead, the first tightening groove and the second tightening groove are vertically spaced apart as a common tightening member for a large number of can bodies arranged on a circular track. By rotating the disk provided on the outer circumferential surface in a certain direction,
While moving the can body in the same direction as or in the opposite direction to the rotating direction of the disc, the process of sequentially bringing the can body closer to the first and second winding grooves of the disc, bringing them into pressure contact, and then moving the can body back is repeated. Since a double-sealed part is formed, a large number of chucks and lids should be arranged close to each other, in other words,
The area (space) occupied by a set of seaming devices is small, and the seaming can be done by advancing can bodies one after another while maintaining a narrow interval, which improves seaming efficiency and increases the seaming efficiency of the seaming device. The configuration can also be simplified.

A seaming groove is provided in the lower part, and after the first seaming part is formed, the can body 3 is
The can body is lowered to form the second seam tightening part, but the vertical position of the seam groove is not limited to this, and after forming the first seam tightening part by turning the seam upside down, the can body is raised. It is also possible to form the second seam tightening portion.

るものではない。Furthermore, as in this embodiment, if the traveling direction of the can body is opposite to the rotating direction of the disk 20, the seaming speed of the can body (rotational speed of the can body) can be increased and the seaming can be done efficiently. However, even if the direction is the same, there is no need to provide the first and second seaming members for each can body, each can body can share one seaming disk, and the distance between each can body can be kept close. This does not deviate from the gist of the present invention in that a large number of them can be arranged around the disk to perform double seaming, and the seaming efficiency is improved compared to the conventional method.

効果を奏する。[Effects of the Invention] The present invention provides a first winding groove and a second winding groove that are vertically spaced apart from each other on the outer circumferential surface of the disk, and that the first winding groove and the second winding groove are spaced apart from each other on the outer circumferential surface. A can body (a can body with a can lid attached to it) which is clamped from above and below between a set of chucks and lids is rotated with the outer side of the disc in the same direction or in the opposite direction to the rotating direction of the disc. As the can body advances, the process of bringing it closer and pressing it and separating it is repeated to form the seaming part, so it is placed around a pair of chucks and lifters that clamp and hold the can body from above and below, Compared to the conventional method in which the seaming portion is formed by a rotating first seaming roll and a second seaming roll, each set of chuck and lids is arranged in large numbers with close spacing between them, in other words, Since the can bodies can be advanced and tightened one after another while maintaining narrow intervals, the seaming efficiency is improved and the configuration of the seaming device is also simplified.
