Title: Bag packaging machine
Inventor: ICHIKAWA MAKOTO
IPC: B65B61/02
Filed: 2020-03-23
Abstract: To provide a bag packaging machine capable of switching a printing mode to a printing mode suitable for production on the basis of information inputted during production.SOLUTION: In a bag packaging machine 1, a control part 7, when determining that it is the timing of printing on a film F when the film F is conveyed on the basis of previously input information, switches a printing mode to a first printing mode. The control part 7, when determining that it is the timing of printing on the film F when the film F is stopped on the basis of previously input information, switches a printing mode to a second printing mode. Since a printing mode, regardless of whether bags are continuously produced or intermittently produced, is determined by a timing of printing on a packaging material, a printing mode suitable for production is selected, which results in prevention of erroneous operation, with no need for an operator to be aware of which printing mode is used for operation.SELECTED DRAWING: Figure 7

Abstract: To deterioration of the long-term reliability due to occurrence of a crack in a resin in a nonaqueous electrolyte secondary battery using laminate films as an outer packaging body.SOLUTION: A nonaqueous electrolyte secondary battery comprises: an outer packaging body 2 formed by laminate films 10, 20; and a power storage element 3 and a nonaqueous electrolyte encased in the outer packaging body 2. Peripheral edges 12, 22 of the laminate films 10, 20 are sealed to each other. In seal parts 12T, 12B, 12S, 12D forming the peripheral edge 12, a thin part 13 where a thickness of a metal layer 6 is made small locally is provided. Thus, a resin layer 7 which tends to move toward the power storage element 3 in a heat-sealing step can be suppressed by the thin part 13, and thereby a resin amount on the side of the power storage element 3 can be made a correct amount. As a result, the cracking owing to stress concentration becomes hard to occur. So it becomes possible to increase the long-term reliability. The present invention makes contribution to the achievement of a goal of sustainable development from the viewpoint of stable energy supply.SELECTED DRAWING: Figure 4
