Description

This invention relates to a bag-making and packaging machine. A bag-making and packaging machine is known that manufactures a continuous bag with a header, comprising multiple storage bags containing articles and a header provided above these multiple storage bags. Such a bag-making and packaging machine is disclosed, for example, in Patent Document 1 (Japanese Patent Application Publication No. 2009-83894). Patent Document 1 discloses a method in which an end seal mechanism applies end seals at predetermined intervals in a direction intersecting the conveying direction to a tubular film continuously conveyed by a film feeding mechanism, thereby attaching a header, which becomes an empty bag, to one end of the multiple storage bags containing articles. This is a perspective view of a packaging machine, including a bag-making and packaging machine according to an embodiment.This is a schematic diagram of a packaging machine including a bag-making and packaging machine according to an embodiment.This is a schematic diagram showing a continuous packaging bag according to the embodiment.This is a schematic side view showing the lateral sealing portion, bag, etc., of the embodiment.This is a perspective view showing the schematic configuration of the bag-making and packaging machine according to the embodiment.This is a block diagram of a bag-making and packaging machine according to an embodiment.This is a schematic diagram illustrating the process by which the bag-making and packaging machine of this embodiment manufactures continuous bags.This is a schematic diagram showing the process of a modified bag-making and packaging machine manufacturing continuous bags. A bag-making and packaging machine 100 according to one embodiment of the present invention will be described below. In the following description, terms such as "front," "rear," "top," "bottom," "left," and "right" may be used to indicate direction, etc. Unless otherwise specified, "front," "rear," "top," "bottom," "left," and "right" here refer to the direction of the arrows indicated in the drawings. (1) Overall Overview Figure 1 is a perspective view of the packaging machine 1 including the bag-making and packaging machine 100 of this embodiment. Figure 2 is a schematic diagram of the packaging machine 1 including the bag-making and packaging machine 100 of this embodiment. In Figures 1 and 2, the packaging machine 1 is equipped with a weighing machine 2 and a bag-making and packaging machine 100. Figure 3 is a schematic diagram showing a continuous bag C manufactured by the bag-making and packaging machine 100 of this embodiment. The bag-making and packaging machine 100 shown in Figures 1 and 2 is capable of manufacturing a continuous bag C in which multiple bags B containing the article A shown in Figure 2 and a header H are integrally connected, as well as manufacturing a single, unconnected bag B. In the continuous packaging bag C, multiple bags B and the header H are connected to each other by perforations S. The number of bags B constituting the continuous packaging bag C is not limited to two or more. In this embodiment, a continuous packaging bag C having four bags B and a header H is manufactured. Multiple bags B have the same bag length (vertical distance). The bag length of the header H is smaller than the bag length of each bag B. The header H does not contain any articles A. Furthermore, the header H has punch holes P formed as a hanging section. In Figure 3, the bags B constituting the continuous packaging bag C are labeled as bags B1, B2, B3, B4, and header H in order from the front (as they are manufactured). Each bag B constituting the continuous packaging bag C has a horizontal seal area X and a vertical seal area Y. The horizontal seal area X is formed horizontally between each bag B. In Figure 3, horizontal seal areas X0 to X4 are formed at the upper and lower ends of each bag B. Perforations S are formed at the horizontal seal areas X between each bag B. The vertical seal area Y is formed vertically on each bag B. As shown in Figures 1 and 2, the weighing machine 2 weighs the item A to be placed in bag B. Item A is not particularly limited, but in this case, it is a food item such as potato chips. The bag-making and packaging machine 100 is installed below the weighing machine 2. The bag-making and packaging machine 100 receives item A from the weighing machine 2 and manufactures bag B by packaging item A with a tubular film F (hereinafter also referred to as tubular film Fm). The bag-making and packaging machine 100 comprises a film supply unit 10 (shown in Figures 1 and 2), a former unit 20, a film feeding unit 30, a vertical sealing unit 40, a horizontal sealing unit 50, a squeezing unit 60 (shown in Figure 4), a gas venting unit 70, a bag beating device 80 (shown in Figure 5), and a control unit 90 (shown in Figure 6). Figure 4 is a schematic side view showing the horizontal sealing unit 50, bag B, etc., of this embodiment.
