Conveying apparatus and rotary type transfer apparatus for spout-equipped bags

A rotary type transfer apparatus for spout-equipped bags in which said spout-equipped bags are received from a plurality of first spout holding members which are disposed on a circumference of a working rotor that rotates continuously at a constant speed, and said spout-equipped bags are rotationally conveyed and transferred to a rail type conveying apparatus installed on a downstream side of said rotary type transfer apparatus, said rotary type transfer apparatus further comprising:

• a transfer rotor which has a plurality of second spout holding members disposed on a circumference thereof, and
• a driving means which causes said transfer rotor to rotate intermittently at predetermined angle at a time in a predetermined cycle of stopping, acceleration, constant speed, deceleration and stopping, said driving means causing a speed of said second spout holding members during said constant-speed rotation to coincide with a speed of said first spout holding members and causes said first and second spout holding members to run side by side,
• wherein said second spout holding members receive said spout-equipped bags from said first spout holding members during said constant-speed rotation, and said spout-equipped bags are transferred from said second spout holding members to said rail type conveying apparatus provided on a downstream side at a predetermined stopping position of said second spout holding members.
