  • Publication number: 20180078991
    Abstract: Provided is a seaming device that makes it possible to easily adjust an axial load applied to a can during seaming and that makes it possible to prevent the buckling of the can without any shock load being applied, apply a constant axial load according to a decrease in the height of the can during the seaming, and achieve the high speed of a seaming process. The seaming device has a can placement unit (110) that places a can (C), a chuck unit (120) provided opposite the can placement unit, and a seaming roll (131) that seams a lid (F) onto the can (C). The can placement unit (110) has a pressing mechanism (111) that operates by fluid pressure and elastically upwardly presses a plate (112) on which the can (C) is placed.

  • Publication number: 20180065168
    Abstract: Provided is a seaming device capable of preventing dents, caused by a can guide or a seaming turret pocket, and buckling resulting from the dents during seaming, and capable of improving seaming accuracy, by stabilizing the posture of the can being transferred when the can is supplied from an infeed conveyor. The seaming device (100) includes a can placement unit (110) that places a can (C), a seaming chuck unit (120) provided opposite thereto, and a seaming roll (131) that seams an opening of a can (C) and a lid (F). The can placement unit (110) includes a pressing mechanism (111) that presses a plate (112), on which a can is placed, resiliently upward. The seaming chuck unit (130) and the seaming roll (131) are configured to be capable of moving up and down.

  • Patent number: 9003851
    Abstract: To provide an embossing device, an embossing method and an embossed can which are capable of conducting embossing having a non-shaped section and an arbitral number of embossed areas, and are capable of improving quality or productivity. An embossed can 10 is a double-embossed surface can in which on a can barrel 101 a first pattern 104 is printed; a first concave part 105 is formed in the state that it is so positioned as to almost conform to the first pattern 104; a second pattern 106 is printed at a position which is distant in the circumferential direction with the non-shaped section therebetween; and a second concave portion 107 is formed in the state that it is so positioned as to almost conform to the second pattern 106.

  • Patent number: 6338263
    Abstract: A method for manufacturing an embossed can body with a pattern printed on an outer surface of a cylindrical can barrel includes a plastic working step for forming a flange portion and a neck portion at an opening peripheral edge of the can barrel, and an embossing step for forming an embossed portion on at least a part of the pattern while aligning with the pattern. Thus, the pattern and the embossed portion can be aligned easily and accurately. Also, a stopping mark and a confirmation mark are formed on the can barrel, and a first sensor corresponding to the stopping mark and a second sensor corresponding to the confirmation mark are used. When the respective first and second sensors detect the stopping mark and the confirmation mark, it can be confirmed that the pattern on the can barrel is oriented in a predetermined direction.
