Abstract: A rotor head includes a hub and two joint members. The hub has opposite tubular end portions, each formed with a socket that extends inwardly from an end face thereof along a tube axis and that has inner and outer socket sections. Each of the joint members includes a link and a vibration absorbing component. The link has a hub coupling segment retained rotatably in the inner socket section of a respective socket, an intermediate segment extending from the hub coupling segment and disposed movably in the outer socket section of the respective socket, and a blade coupling segment extending from the intermediate segment and outwardly of the outer socket section. The vibration absorbing component is mounted on the intermediate segment, and is disposed in the outer socket section.

Abstract: A specification-attaching apparatus includes a transferring unit for transferring a specification fed from a specification-feeding unit to an attaching unit that includes a suction member movable, in response to rotation of a pivot rod, in sequence among angularly spaced sucking, standby and releasing positions. The suction member is operable so as to switch from a non-sucking state to a sucking state when at the sucking position, thereby sucking the specification transferred from the transferring unit and to switch from the sucking state to the non-sucking state when at the releasing position, thereby releasing the specification sucked thereby. A container sprayed with glue by a glue-spraying unit is conveyed by a motor-driven container conveying unit to move in synchronization with and contact the suction member during movement of the suction member from the standby position to the releasing position so that the specification is attached to the container.

Abstract: A transmission device includes: a transmission shaft having first and second shaft sections and a gear mounting portion; a first tube sleeved rotatably on the first shaft section, and including a tube body and an annular portion; a second tube sleeved on the second shaft section; a plurality of first planetary bevel gears mounted rotatably on the gear mounting portion; a plurality of second planetary bevel gears mounted rotatably on the annular portion; a transmission gear disposed rotatably on the tube body and meshing with the first and second planetary bevel gears; a first output bevel gear disposed rotatably on the second tube and meshing with the first planetary bevel gears; and a second output bevel gear disposed rotatably on the tube body of the first tube and meshing with the second planetary bevel gears.

Abstract: An apparatus for tightening and loosening caps on containers includes a support, a rotary member mounted rotatably on the support and rotatable about a rotation axis, a complementary unit that is complementary to and that cooperates with the rotary member to define a cap passage therebetween, and a driving unit for driving the rotary member to rotate about the rotation axis. At least one of the rotary member and the complementary unit is pivotable relative to the support so as to permit passage of the cap through the cap passage.
