• the delivery package of unit-load sacks as described in the FI Patent No. 91,141 can be handled at the filling site readily and quickly, for example, as follows.
• An automatic device included in the filling equipment grasps the inner sack of the unit- load sack and unloads one unit-load sack at a time from the delivery package or reel package, and transfers the unit-load sack to the filling position. Then, no additional operations are required concerning the arrangement of the unit-load sacks when the sacks are filled with bulk goods.
• the object of the present invention is to provide an improvement for the methods of filling of unit-load packages. It is a more specific object of the invention to provide a method of filling of unit-load packages in which the package of transportation of the unit-load packages can be used directly in an automatic filling station.
• the method in accordance with the invention is characterized in that the fixed filling part of the unit-load packages is placed in the package of transportation systematical ⁇ ly so that a mechanical device can find it clearly in the package of transportation, that the positioning of the unit-load packages from the package of transportation to the filling position is fitted to take place directly by the fixed filling part provided on the unit-load package, in which case the mechanical device always finds the next unit-load package to be filled automatically and carries one unit-load package at a time to the filling position.
• the filling part for unit-load packages used in the method of the present invention is characterized in that the filling part is a fixed filling part provided on the unit-load package, which filling part may be provided with an identification member to facilitate the alignment of the unit-load package.
• the package of transportation for unit-load packages in accordance with the inven ⁇ tion is characterized in that the location of the fixed filling part of the unit-load package that follows after each unit-load package is known in advance.
• the unit-load packages may be placed in the package of transportation in a reel, in a cassette, placed in a box or on a pallet.
• the positioning of the packages from the package of transportation to the filling position takes place directly by the filling part fixed to the unit- load package.
• the unloading from the package of transportation takes place directly by the fixed filling part of the unit-load package.
• the fixed filling part is preferably provided with grasping points or marks, by whose means the grasping member or pick-up device of the robot can unload one unit-load package at a time.
• the unit-load packages are placed so that the location of the filling part of the unit-load package placed next in the package of transportation is known in advance.
• An identification member on the fixed filling part is, however, not indispensable, but the grasping member of the robot may also seek the filling part based on the position or the shape of the unit-load packages alone.
