  (Description of packaging material alignment part)

  Next, FIG. 4 is a schematic perspective view of the packaging material aligning portion constituting the rolled sushi packaging apparatus, FIG. 5 is a conceptual view of the packaging material aligning portion of FIG. 4 viewed from above, and FIG. 6 is the packaging material aligning portion of FIG. It is the conceptual diagram which looked at from the side.

  The packaging material alignment unit 3 is installed in the middle of the path of the transport belts V1 and V2, and includes a packaging material mounting table (mounting unit) 3a, a pressing member 3b, and positioning members (first and second positioning members). 3c, 3d, push molds (first and second moving members) 3e, 3f, and push mold drive units (drive units) 3g, 3h.

  The packaging material mounting table 3a is a mounting table on which the packaging material P is placed when the packaging material P is aligned, and is installed in a state in which the packaging material alignment position can be moved up and down. When the packaging material P is aligned, the packaging material placing surface of the packaging material placing table 3a is arranged at a position higher than the packaging material placing surface of the transport belts V and V2. As a result, during the alignment operation of the packaging material P, the packaging material P is attached to the transport belts V1 and V2, or the packaging material P is displaced due to the transport belts V1 and V2. Since the malfunction resulting from being affected by V1 and V2 can be prevented, the positioning accuracy of the packaging material P can be further improved.

  In addition, a valve (negative pressure releasing means) (not shown) for releasing the adsorption state of the packaging material P due to negative pressure is provided at the packaging material alignment position. This valve is provided in the course of the air supplied by the blower motor or the like, and controls the adsorption and release of the packaging material P by negative pressure by opening and closing the valve. By providing such negative pressure releasing means, the packaging material P sticks to the transport belts V1 and V2 during the alignment operation of the packaging material P, or the position of the packaging material P shifts due to the transport belts V1 and V2. Therefore, it is possible to prevent problems caused by the packaging material P being affected by the conveyor belts V1 and V2, and the positioning accuracy of the packaging material P can be further improved.

  The pressing member 3b is a member that sandwiches and spreads the packaging material P together with the packaging material mounting table 3a when the packaging material P is aligned, and is installed above the packaging material mounting table 3a in a state in which it can move up and down. When the packaging material P is pressed by the pressing member 3b, a gap of several millimeters is secured between the opposing surfaces of the packaging material mounting table 3a and the pressing member 3b so that the packaging material P can move.

  The packaging material pressing surface of the pressing member 3b is formed, for example, in a planar quadrangular shape and is sized to cover at least the main body portion P1 of the packaging material P. However, the shape of the packaging material pressing surface of the pressing member 3b is not limited to this, and can be variously changed. For example, a shape capable of pressing a part of the packaging material P such as a cross shape is also possible. good. Thereby, since the packaging material P can be visually recognized at the time of alignment of the packaging material P, it can be confirmed whether the packaging material P is positioned normally.

  The positioning members 3c and 3d are members that determine the planar position of the packaging material P. The first side S1 (see FIG. 5) of the packaging material P and the second side S2 (see FIG. 5) orthogonal to the first side S1. It is arrange | positioned in the position facing. That is, the positioning member 3c extends along one side of the packaging material pressing surface of the pressing member 3b and is installed in a state of protruding downward from the packaging material pressing surface. On the other hand, the positioning member 3d extends along the other side perpendicular to the side where the positioning member 3c is provided on the packaging material pressing surface of the pressing member 3b, and projects downward from the packaging material pressing surface. It is installed at. The positioning members 3c and 3d are formed integrally with the pressing member 3b. However, the positioning members 3c and 3d are not limited to be installed in a state extending along the side of the pressing member 3b, and are divided into a plurality of portions along the side of the pressing member 3b. May be installed. Further, the positioning members 3c and 3d may be formed separately from the pressing member 3b.

  The pressing dies 3e and 3f are members that move the packaging material P until it comes into contact with the positioning members 3c and 3d when the packaging material P is aligned, and in a direction orthogonal to each other along the packaging material mounting surface of the packaging material mounting table 3a. It is installed so that it can move back and forth.

  The packaging material P is moved by the pressing dies 3e and 3f in a state where the packaging material P is expanded by the pressing member 3b. Moreover, the movement of the packaging material P by the pressing dies 3e and 3f is performed separately instead of simultaneously. The packaging material P may be deformed in a curved shape due to the deformation of the inner winding material W. However, if the packaging material P is deformed when the packaging material P is aligned, the dimensional error due to the deformation may be absorbed. The position of the packaging material P will shift | deviate. In particular, when the position is determined by pressing the packaging material P with a structure, the deformation of the packaging material P increases due to the pressing of the structure, and as a result, the positional deviation amount of the packaging material P also increases. For this reason, there is a problem that the food F cannot be packaged well and packaging failure occurs.

  On the other hand, in the present embodiment, when the packaging material P is aligned, the packaging material P is spread and flattened by the pressing member 3b, and the position is determined by moving the packaging material P with the pressing dies 3e and 3f. The planar positioning accuracy of the material P can be improved. For this reason, since the foodstuff F can be packaged with the packaging material P with good alignment, the occurrence rate of the packaging material misalignment or the like in which the side of one end of the packaging material P in the winding direction is obliquely shifted with respect to the axis of the foodstuff F is reduced. Or it can be prevented. Therefore, the mass productivity of the product which wraps the foodstuff F with the packaging material P can be improved.

  Further, when the packaging material P is aligned, a gap of several millimeters is secured between the packaging material placing table 3a and the pressing member 3b as described above, and therefore the packaging material P is placed on the packaging material placing table 3a. It can be moved along the placement surface.

  The pressing molds 3e and 3f are mechanically connected to the pressing mold driving units 3g and 3h via support shafts 3i and 3j, respectively. The pressing die driving units 3g and 3h are driving units for driving the pressing dies 3e and 3f, respectively, and are installed on the pressing member 3b. By installing the pressing mold drive units 3g and 3h on the pressing member 3b, the movement accuracy of the pressing molds 3e and 3f can be improved, so that the planar positioning accuracy of the packaging material P can be improved. The rolled sushi packaging apparatus 1 can be reduced in size.

  In this way, in the packaging material alignment unit 3 of the rolled sushi packaging device 1 of the present embodiment, the planar position of the packaging material P can be set with high positioning accuracy with a simple structure. P can be packaged with good alignment, and the occurrence rate of packaging material misalignment or the like can be reduced or prevented. Therefore, the mass productivity of the product which wraps the foodstuff F with the packaging material P can be improved.

  (Description of packaging material alignment method)

  Next, an example of the packaging material alignment method will be described with reference to FIGS. 7 and 8 are conceptual diagrams of an example of the packaging material alignment portion in the packaging material alignment process viewed from the side surface side.

  First, as shown in FIG. 6, the packaging material P is transported to the alignment position by the transport belts V1 and V2. When the packaging material P is transported, the packaging material P is transported while being adsorbed to the transport belts V1 and V2 by negative pressure. At this stage, the packaging material placement surface of the packaging material placement table 3a is positioned below the packaging material placement surface of the transport belts V1 and V2. Further, the pressing member 3b is located immediately above the packaging material mounting table 3a.

  Subsequently, the adsorbed state of the packaging material P due to the negative pressure is released. That is, the supply of air for forming the negative pressure is stopped by closing the valve provided in the air supply path. Thereafter, as shown in FIG. 7A, the packaging material mounting table 3a is raised so that the packaging material mounting surface of the packaging material mounting table 3a is positioned above the packaging material mounting surface of the transport belts V1 and V2. Let As a result, during the alignment operation of the packaging material P, the packaging material P is attached to the transport belts V1 and V2, or the packaging material P is displaced due to the transport belts V1 and V2. Since the malfunction resulting from being affected by V1 and V2 can be prevented, the positioning accuracy of the packaging material P can be further improved. According to the inventor's experiment, after releasing the adsorption state of the packaging material P due to the negative pressure, raising the packaging material mounting table 3a is an important factor in improving the positioning accuracy of the packaging material P. Has been confirmed.

  Thereafter, the pressing member 3b is lowered, and the packaging material P is sandwiched between the packaging material mounting table 3a and the pressing member 3b so as to be flattened. At this time, a gap d of several millimeters is ensured between the facing surfaces of the packaging material mounting table 3a and the pressing member 3b.

  Next, as shown in FIG. 7A, the pressing die 3e is moved toward the positioning member 3c via the packaging material P, and the first side S1 of the packaging material P (see FIG. 5: packaging material P). The movement is stopped when the side opposite to the side on which the pressing die 3e is in contact with the positioning member 3c. Subsequently, the pressing die 3f is moved toward the positioning member 3d via the packaging material P, and the second side S2 of the packaging material P (see FIG. 5: the side of the packaging material P where the pressing die 3f is in contact). The movement is stopped when the opposite side) contacts the positioning member 3d. In this way, the planar position of the packaging material P is determined.

  At this time, since the gap d of several millimeters is secured between the packaging material mounting table 3a and the pressing member 3b as described above, the packaging material P is moved along the packaging material mounting surface of the packaging material mounting table 3a. Can be moved. In the present embodiment, the packaging material P is moved and moved by the pressing dies 3e and 3f in a state where the packaging material P is flattened by the pressing member 3b when the packaging material P is aligned. The planar positioning accuracy can be improved. For this reason, since the foodstuff F can be packaged with the packaging material P with good alignment, the occurrence rate of the packaging material misalignment or the like can be reduced or prevented. Therefore, the mass productivity of the product which wraps the foodstuff F with the packaging material P can be improved.

  Subsequently, as shown in FIG. 8A, the pressing dies 3e and 3f are sequentially moved in the direction away from the packaging material P, and then the pressing member 3b is raised as shown in FIG. 8B. Thereafter, the packaging material P is placed on the transport belts V1 and V2 by lowering the packaging material mounting table 3a. Further, the packaging material P is attracted to the conveyor belts V1 and V2 by negative pressure so that the packaging material P does not shift. Thereby, the packaging material P can be conveyed to each part of conveyance downstream in the state which fixed the position of the packaging material P determined with high precision. In this way, a series of alignment work of the packaging material P is completed.
