[Prior art]
Normally, deep-drawn packaging products such as ham and other vacuum packaging products are discharged from the deep-drawing packaging machine in three rows, and the three rows of packed products are combined into one row, which is the next process, inspection process, product connection process, and box packing. It is transported to the process. For this reason, conventionally, as shown in FIG. 1, the first conveyor C <b> 1 that conveys the three rows of ham packs P discharged from the deep-drawing packaging machine and the three rows of ham packs P can be changed to one row. A transfer device that includes a second conveyor C2 provided at the end of the first conveyor C1 in a direction orthogonal to the transfer direction of the first conveyor C1 has been used. However, in this conventional apparatus, since the ham packaging P is transferred to the second conveyor C2 in a direction perpendicular to the conveying direction of the first conveyor C1, the second conveyor C2 is stopped at the time of transfer. Even so, the ham package P may be biased toward the end of the conveyor, may be oriented in different directions, or may overlap in some cases, and thus there is a problem that accurate foreign object detection inspection and measurement cannot be performed. However, there was a problem that the product connection process and the boxing process could not be automated.
[0003]
In particular, as shown in FIG. 2, in a vacuum packaging body P such as a ham by a deep-drawing packaging machine, when discharged from the packaging machine, the conveyor is placed in an inverted state, that is, with an upper surface portion S that is unstable due to distortion being placed downward. Since it is discharged and placed on the upper side, the vacuum package is biased toward the end of the conveyor C or in different directions compared to the case where the flat and stable bottom surface portion B is placed on the conveyor. They often faced and sometimes overlapped. For this reason, the position and orientation of the vacuum package that is being transported must be corrected manually, which has become a major obstacle to automation of the packaging line, as well as increased labor costs and sanitary aspects. Was occurring as.
