If comprised in this way, it will become possible to perform a fine adjustment easily compared with the manual operation which requires a certain amount of proficiency.

In such a configuration, it is preferable to further combine the following configurations. That is, the adjustment member to be individually adjusted by the sub-adjusting means is configured by a member that moves in a direction in which the member is moved toward or away from the packaged object being conveyed, and the position where the member is farthest from the packaged object is the fully open position. Is set as
It is preferable that the sub-adjusting unit has a function of moving an adjustment member to be individually adjusted to a fully opened position by operating the individual operation tool.
Thus, by providing the function of moving the adjusting member to the fully open position, it becomes possible to quickly remove the packaged object and restore it when a failure such as the packaged item being jammed occurs.

  In addition, when the main adjustment means includes a plurality of adjustment motors that move each adjustment member in the position adjustment direction and a collective operation tool for collectively driving these plurality of adjustment motors, It is preferable to reduce the number of parts by causing the adjustment motor constituting the main adjustment means to function as the adjustment motor constituting the auxiliary adjustment means.

  According to the present invention, in addition to the main adjustment means, the adjustment member to be individually adjusted is provided with the auxiliary adjustment means in the vicinity of the adjustment member. Therefore, in addition to the position adjustment performed collectively for each adjustment member, The adjustment member selected as the individual adjustment target can be finely adjusted individually in the vicinity thereof, so that highly accurate position adjustment can be realized and the operation efficiency can be improved.
