More than a book.

  Both end portions in the width direction of the bracket plates 85 and 86 attached to the part from the sprocket 72 to the sprocket 71 in the endless chain 82 are placed on the guide rail 79b to prevent the part from the sprocket 72 to the sprocket 71 from being bent. Has been. As the endless chain 82 circulates, the bracket plates 85 and 86 on the guide rail 79b slide relative to the guide rail 79b in the transport direction.

The posture holding device 70 configured as described above is operated together with the film supply device 10, the package supply device 20, the transport device 30, the unloader 35, the vertical seal device 50, and the horizontal seal device 60.
As described above, when the article 4 to be packaged supplied to the bag making machine 18 by the article supply machine 20 passes through the bag making machine 18 to the downstream side, the tips of the contact bars 87 and 88 are above the cylindrical film 5. Is lightly abutted against the package 4. Specifically, as shown in the plan view of FIG. 7, the downstream portion of the article to be packaged 4 is pressed from the top by the tip of the hitting bar 87, and the upstream portion of the article to be wrapped 4 is Pressed by the tip. Here, FIG. 7 is a plan view of a portion between the carriage 28 and the receiving plate 58.

  Thereafter, the package 4 and the film 5 are transported to the lateral sealer 60 by the drive motor and transporter 30 of the film feeder 10, but the tips of the contact bars 87 and 88 are covered with the endless chain 23. While maintaining the state of being abutted against the package 4, it moves to the lateral sealer 60 together with the package 4. Therefore, the attitude of the article 4 to be packaged is maintained. That is, the downstream portion of the article to be packaged 4 is supported by the two batting bars 87 and the upstream portion of the article to be wrapped 4 is supported by the two batting bars 88. It does not rotate around the axis. Furthermore, since the article to be packaged 4 is pressed from above by the contact bars 87 and 88, the article to be packaged 4 does not roll around the axis in the width direction. Since the batting bars 87 and 88 are in soft contact with the film 5 to such an extent that the packaged object 4 and the film 5 are not greatly deformed, the film 5 is not pulled so as to be attracted to the batting bars 87 and 88. No wrinkles occur.

  When the contact bars 87 and 88 and the bracket plates 85 and 86 move to the drive sprocket 71, the tips of the contact bars 87 and 88 are separated from the tubular film 5 and the packaged object 4, and the packaged object 4 is moved to the lateral sealing machine 60. Enter.

10. Effect (1) The package 4 is pressed from above by the contact bars 87 and 88 that move to the downstream side at a speed equal to the conveyance speed of the package 4, and the lateral sealer 60 is moved from the bag making machine 18. It is conveyed to. In particular, the downstream and upstream portions of the package 4 are supported by the contact bars 87 and 88, respectively. Therefore, the package 4 is stationary relative to the film 5, and the posture of the package 4 is stabilized. Therefore, the article to be packaged 4 is not sandwiched between the press contact portions 61 and 62.

(2) By rotating the rotary handle 78, the heights of the endless chain 82 and the sprockets 71 to 73 can be adjusted according to the thickness of the article 4 to be packaged. The distance to the upper surface of the conveyor belt 30a of the conveyor 30 can be adjusted.

(3) By rotating the male screws 87a and 88a with respect to the nuts 87b, 87c, 88b and 88c, the receiving plate 58 and the transporting machine are moved from the tip of the contact rods 87 and 88 in accordance with the thickness and shape of the package 4. The distance to the upper surface of the 30 conveyance belts 30a can be adjusted. Moreover, according to the thickness and shape of the article 4 to be packaged, the positions of the contact bars 87 and 88 can be adjusted along the longitudinal direction of the long holes 85a and 86a. According to the length of the article 4 to be packaged, it is possible to select the plurality of elongated holes 85a and 86a and attach the contact bars 87 and 88.

(4) By loosening the fixing screw 79a, the positions of the frame 79 and the drive sprocket 71 can be adjusted along the conveying direction, and the position of the downstream end of the moving range of the moving body 84 and the contact bars 87, 88 can be adjusted. . Therefore, the article to be packaged 4 is appropriately delivered from the posture holding device 70 and the transport device 30 to the unloader 35 via the lateral sealing device 60.

(5) Loosen the fixing screws 80a and 81a, adjust the positions of the adjusting plates 80 and 81 and the driven sprockets 72 and 73, and adjust the position of the upstream end of the moving range of the moving body 84 and the contact bars 87 and 88. Can do. Accordingly, the article 4 is appropriately delivered from the article supply machine 20 to the posture holding device 70 and the receiving plate 58 via the bag making device 18.
