PROBLEM TO BE SOLVED: To ensure a stable rapid process when a spout S set at a specified position is to be delivered to a retaining member 26 installed at a continuously rotating rotor 23. SOLUTION: A delivery rotor 151 with a plurality of gripping teeth 152a formed on the periphery is used and a spout is received by the gripping teeth 152a and is delivered to the spout retaining member of a continuously rotating rotor 23 after the conveyance of the spout. The delivery rotor 151 intermittently rotates at every 60 deg. angle in a cycle of stop, acceleration, constant velocity, deceleration and stop. When the delivery rotor 151 stops, the gripping tooth 152a which stops at a receiving position A receives the spout and is synchronized with the velocity of the spout retaining member during the constant velocity rotation of the tooth 152a and then both gripping teeth 152a and spout retaining members are made to run in parallel. On the other hand, the spout is delivered to the spout retaining member from the gripping tooth 152a. At the delivery position B, the gripping tooth 152a is opened and the spout moves along a guide member 155 following the rotation of the spout retaining member and is thrust into the innermost depth of a retaining groove 26a of the spout retaining member. |
