Dumping apparatus for bag filled with molten substance

A dumping apparatus for a bag filled with molten substance, comprising:

• a tippler having first and second transfer positions;
• a roller conveyor including a plurality of rollers for receiving a carrying can in which the bag filled with molten substance is accommodated and transporting the carrying can to the first transfer position at which the carrying can is to be transferred to said tippler;
• a pallet conveyor for receiving and positioning a pallet to the second transfer position at which the carrying can is to be transferred from said tippler to the pallet;
• said tippler having a plurality of first portions which extend horizontally between adjacent ones of said rollers of said roller conveyor when said tippler is at the first transfer position and a second portion which extends vertically when said tippler is at the first transfer position;
• tippler moving means for pivoting said tippler around a stationary axis parallel to a transporting direction of said roller conveyor alongside said roller conveyor from the first transfer position to the second transfer position at which said second portion of said tippler is inclined downwardly toward said pallet conveyor to allow the carrying can to slip down somewhat along said second portion, said tippler receiving, at said second portion thereof, the carrying can when said tippler is pivoted from the first transfer position to lift said second portion thereof from between the adjacent ones of said rollers of said roller conveyor;
• and
• pallet conveyor moving means for moving, after said tippler is pivoted from the first to the second transfer position together with the carrying can until the bag is partially received on the pallet, said pallet conveyor away from said tippler to pull out the bag from the carrying can thereby to transfer the bag to the pallet.
