  • carton 2 is transported and waiting directly below the location where the damper plates are installed as described later and four flaps 2a at the top opening of the carton are forcefully opened by the operation of both two flap kickers 68 and two damper plates 63 mentioned above.
  • bagged products 1 which are held with holding plates 30 mentioned above are placed into corrugated carton 2 which is waiting below.
  • the holding pressure is released from holding plates and then only holding plates are lifted up to complete the placing operation of the bagged products into the carton. Furthermore, at the time of placing bagged products into carton 2 as mentioned above, since the holding pressure is released from holding plates 30, respective bagged products expand a little due to the reaction force of air or nitrogen gas filled in the bags which is one of the reasons why the bagged products can be packed into corrugated carton 2 in comparatively tight condition. Furthermore, holding plates 30 are lifted up as mentioned above, then damper plates 63 return to the location shown by the full line in FIG.12 (D) by the operation of driving motor 77 or pinion 112 via lifting plate 71 and flap kickers 68 are lifted up to return to the original waiting position.
  • FIG.14 (A) to (C) illustrate the example of the mechanism to carry in carton 2 directly below damper plates 63 and to carry it out after bagged products are packed.
  • Symbol 80 shows the roller conveyor for carrying in or out the carton, which is installed parallel to supply conveyor 4 of bagged products 1 as it is clear in FIG.2 to 4. Before the bagged products are placed into corrugated carton 2 with holding plates 30, the carton mentioned above must be carried in directly below the plates in advance and made to be waiting.
  • the example of a conveyor for this is the roller conveyor shown by symbol 80 and the embodiment regarding the stoppers to provisionally stop the transportation of the carton mentioned above in the two locations along the proceeding direction of the conveyor as well as the installation of driving unit for the stoppers is shown in the figure,
  • This side stopper 82 in proceeding direction is for accumulating carton 2, that side stopper 81 is for stopping carton 2 which is carried in directly below holding plates 30 to hold bagged products 1 while they are placed into carton 2 and the respective stoppers mentioned above are provided between rollers of roller conveyor 80.
  • slide plates 87 are attached to the bottom part of the stoppers
  • rack gears 86 are fitted to the side of the slide plates 83
  • pinion gears 87 engage with these racks and further connected to spur gear 89 which is provided in the middle of the shaft via shaft 88 and furthermore, spur gear 89 engages with another spur gear 90 attached to the rotating shaft of driving motor 91 so that the rotation of motor 91 mentioned above raises or lowers both stoppers 81 and 82 at the same time.
  • guide rails 84 shown in FIG.14 (C) are connected to guide plates 85 which are attached to the bottom of slide plates 83 mentioned above so that it is designed that the stoppers mentioned above moves smoothly up and down.
  • corrugated carton 2 is carried in directly below damper plates 68 with roller conveyor 80, then driving motor 91 starts to rotate to raise respective stoppers 81 and 82 between rollers via rack gears 86 and pinion 87, to provisionally stop the carried-in carton 2 directly below the holding plates and to provisionally accumulate the following corrugated cartons 2 with this side stopper 82.
  • both stoppers mentioned above are lowered by the reverse rotation of driving motor 91 and the operation to carry out the corrugated carton filled with bagged products is completed.
  • a new empty corrugated carton is carried in and then the above operation is repeated.
  • FIG.15 (A) to (C) show another embodiment of the transmission mechanism mentioned above, Symbols 130 and 131 are stoppers and these stoppers are different from those mentioned above and are attached to the side of transmitting conveyor 80. Although the stoppers in the embodiment mentioned above are the type coming out of the bottom face of conveyor 80, FIG.15 shows the embodiment of the stoppers 130 and 131 attached to the side of the conveyors for stopping and releasing cartons.
  • symbol 132 is the driving cylinders for respective stoppers mentioned above and the stoppers are projected out of the transmitting surface of conveyor 80 by turning stoppers 90 mentioned above by 90° via rotating units 133 which are connected to the cylinders so that the progress of cartons 2 is interrupted and if required, the operation to allow the transmission of cartons is done by making the stoppers parallel to the transmitting direction.
  • lifter 134 which lifts up the carried-in cartons in the receiving location of bagged products on the bottom face of conveyor 80 in this type of structure.
  • Lifter 134 mentioned above is of the structure to be lifted up with an air cylinder 135 provided at the bottom and symbol 136 shows the lifting plate to directly contact carton 2. Since it is possible to install lifter 134 on the bottom of conveyor 80 in the embodiment shown in FIG.15 (A) to (C), the carried-in carton 2 to the specified position can be lifted up or lowered down with the lifter mentioned above. Therefore, it is possible to handle the cartons of different height with the same apparatus so that there is an advantage to be able to easily deal with the size change of cartons.
  • the present invention comprises a method of holding the products together with holding plates in their front and rear by the holding pressure possible to hold them and of packing them into a corrugated carton, it is possible to pack the products into a carton in a comparatively tight position by this method. Therefore,there are no gaps between product boxes or bags so that the chance for the product boxes or bags to jump up and bump against each other inside the carton during transportation and to break snack foods is fairly-reduced.
