Description

  The present invention relates to a bag packaging body shaping device for attaching a crease to a bag end portion of a bag packaging body manufactured by a packaging machine and formed into a gusset.

  Conventionally, as a bag package body in which a center seal and an end seal are provided and a product is packaged inside, a gusset is folded in the vicinity of at least one end seal portion to form a flat end portion, and the flat end portion is the bottom. There is a bag package that can be placed vertically on the side of the bag package. Since the bag package is placed vertically instead of horizontally, it can be arranged and stored efficiently in a store display shelf or storage space at home without neatly taking up space.

There has been proposed a packaging bag shape that can stand on its own even when the object to be packaged is a soft food product such as a handful. In other words, the opening ends on both the upper and lower sides of the cylindrical packaging film containing the product to be packaged are sealed in a gas-sealed state to form a bag, and the package is a sealed bag-like body. Of the film, a wide bottom for fixing and adhering the overlapping portions of the lower sealing end folded to the rear side or the front side and the left and right side film portions folded in a state of being superposed on it. A structured packaging bag has been proposed (Patent Document 1). By forming the wide bottom portion in the packaging bag (bag package), the lower sealing end of the packaging film overlaps with the wide bottom portion to give strength (rigidity) to the wide bottom portion and cover the gas in a sealed state. Even if the package is stored, the bag package can be made self-supporting without losing its shape.

The exit side of the transport conveyors 11, across the cross point 15, the packaging material Fw traveling while being molded in former 2 is connected. The exit side of the transport conveyors 11, sensor 12 for detecting passage of the product A is located. Transport conveyors 11, shiftable example servo motors, a variable supply conveyors driven by an induction motor or a DC brushless motor or the like drive motor.

  The web-shaped packaging material Fw is guided by the guide roller 8 and fed into the former 2. The paper feed roller 9 that feeds the wrapping material Ft across the mating edge is a packaging material feeding means for feeding the packaging material F, and is driven by a film feed driving motor (not shown). Further, the end sealer 4 is driven by being converted into a vertical motion by an end seal drive motor (not shown). These drive motors are related to each other by adjusting the distance to each other so as to produce an appropriate bag package by the controller or detecting the product by the sensor 12 or performing primary stop or deceleration if necessary. Are controlled to operate.

  The end sealer 4 is of a type that includes a cutter inside, and applies an end seal to the packaging material Ft and separates it from the packaging material Ft to manufacture the bag package P. On the discharge side of the packaging machine 1, a carry-out conveyor 13 as a carry-out device is provided, and the bag package P is placed on the carry-out conveyor 13 and carried out. In this example, the carry-out conveyor 13 is specifically a belt conveyor. Corresponding to the end sealer 4, a folded piece 6 for folding the gusset into the molded bag is provided, which operates at a predetermined timing in conjunction with the operation of the end sealer 4, and from the side to the inside of the bag. The side part of the bag is folded to form gusset folds at the front end and the rear end in the feeding direction.

  This bag packaging body shaping apparatus is applied to a horizontal bag making packaging machine as described above as a packaging machine. That is, a rotary table 20 as a heating conveyor is provided with a step E on the downstream side of the carry-out conveyor 13. The rotary table 20 may rotate continuously or intermittently around the vertical axis 21 and is not shown in the drawing, but an appropriate heating source such as a heating wire is provided inside, particularly corresponding to the peripheral edge where the bag package P lands. Is provided. The bag package P delivered from the discharge end of the carry-out conveyor 13 descends the step E and lands on the peripheral edge of the turntable 20. The turntable 20 has a bag wrapping body placed with the front end part where the gusset is folded as the bottom part, and the end part can be heated and shaped during carry-out, that is, the gusset crease can be attached sufficiently. Time can be obtained.

In this example, the packaging machine Gazette to end p 1 of the produced bag package P sends rear end not only the end p 2 of the direction of the distal end side is formed, the bag package P If it is placed on the rotary table 20 with the end p1 or p2 as the bottom, the end where the gusset is folded is shaped at either end. If the gusset is folded only at one end p2 (p1) of the bag package, when the bag package P is placed on the turntable 20, the end on the side where the gusset is folded is the bottom. It is necessary to place it. As for the end portion p2 on the bottom side, it is preferable that the end portion p2 is correctly folded with respect to the main body of the bag when landing on the turntable 20, and for this purpose, for example, in advance during end sealing, Brazing can be applied parallel to the bottom surface.

The heating table 20 is disposed below the discharge side of the carry-out conveyor 13 with a step E from the conveyance level. Therefore, when the bag package P is discharged from the discharge side of the carry-out conveyor 13, the bag package P is lowered with the end portion p < b > 2 where the gusset folds are formed down and is landed on the turntable 20. When the bag package P lands on the turntable 20, it lands with the momentum when descending the step E, and the momentum when descending is used to promote the shaping of the bottom p 2 gusset.

In this embodiment, the product A being packaged as a bag package can be such as rice ball, and at least a pair of side surfaces a1, products that a2 is formed into substantially parallel two surfaces is. Such a product A may be deformed when the bag package is shaped or carried out. Therefore, the conveyance for feeding the product A into the packaging machine and the feeding inside the packaging machine are performed with the side surfaces a1 and a2 up and down. When the bag package P is transferred from the carry-out conveyor 13 onto the rotary table 20, the bag package P is subjected to a posture change from a state where the bag package P is laid down sideways. Since the internal product A stands on the turntable 20 in the bag package P, it is preferable that the product A is self-standing in such a standing state.

  Each bag package P is conveyed by the rotary table 20 in an angle range of 90 °. When the bag package P is transported from the turntable 20 to the belt conveyor 22 in the tangential direction, the bag package P is aligned vertically with the front and rear bag packages P, that is, the internal grip feeds the side surfaces a1 and a2 in the feed direction. The platoons are changed to a state where they are lined up in both lateral directions. Therefore, when the bag package P is carried out from the rotary table 20 to the belt conveyor 22 while being placed between the two guide plates 23, 23, the side portions of the bag package P corresponding to the pair of side surfaces a1, a2 are always guided. Guided along the plates 23, 23, the deformation of the grip during unloading can be minimized.

  In the illustrated embodiment, the heating conveyor is the rotary table 20, but instead, as shown in FIG. 2 as another embodiment, a belt conveyor 30 having a belt as a heating belt can be used. The end sealer 4 shown in FIG. 2 includes a presser blade 4c and a receiving portion 4d for imparting a crease facing upward to the end seal portion as a seal surface of the heater blocks 4a and 4b. Therefore, when the bag package P is lowered onto the heating conveyor 30, the end p2 of the end seal, which is folded upward in the illustrated example, is transferred while being folded along the bottom on the heating conveyor 30. It will be posted and will not be crushed irregularly.

  The transfer from the carry-out conveyor 13 to the heating conveyor can be performed by a chute provided exclusively for the guide plates 23 and 23. By guiding the descent of the step E of the bag package P to the dedicated chute, the bag package can be accurately landed on the heating conveyor. Moreover, it can replace with the guide plates 23 and 23, and a heating conveyor can also be used as the side belt conveyor using the side belt which pinches | interposes the both sides of the bag packaging body P, and runs endlessly. In this case, the conveyance path is a heating conveyance path, but a fixed type may be used, which is advantageous for maintenance.

  As mentioned above, although the bag packaging body shaping apparatus by this invention was demonstrated as what is applied to the packaging machine which performs a handbag bag packaging, this invention is not restricted to it, The self-supporting property which has general two parallel surfaces, such as Japanese sweets It is clear that it can be applied to certain products.
