Abstract
The installation for the transport of helical-shaped wound springs comprises a star turret with gripper hands. The gripper hands consist of two jaws of which at least one is pivotable and is pressable with the force of a tension spring against the second. The spring produced on the winding machine is pressed by the insertion means into the gripper hand and is held firmly by this by the force of the tension spring during the transport and during the heat treatment. For the transfer of the spring to a transport device insertion jaws are pivotably connected to the transport means and push the spring out of the gripper hand, overcoming at least a part of the tension force of the tension spring, into a receiver on the transport device.
Claims18
An installation for the transport of helical-shaped wound springs from a spring winding device to a heat treatment station and subsequently to a transport means, comprising a star turret rotatably driven intermittently about a rotational axis, with a number of shanks which are directed radially outwards from the star turret each of said shanks terminating in a gripper hand adapted to hold a spring, wherein the gripper hand has two jaws or metal plates of which at least one is mounted about a pivoting axis extending perpendicular to the rotational axis.
An installation for the transport of helical-shaped wound springs from a spring winding device to a heat treatment station and subsequently to a transport means, comprising a star turret rotatably driven intermittently about a rotational axis, with a number of shanks which are directed radially outwards from the star turret, each of said shanks having a shank axis and terminating in a gripper hand adapted to hold a spring, said gripper hand being secured to said shank with a fastener having an axis parallel said shank axis.
An installation for the transport of helical-shaped wound springs from a spring winding device to a heat treatment station and subsequently to a transport means, comprising a star turret rotatably driven intermittently about a rotational axis, with a number of shanks which are directed radially outwards from the star turret, and
- a pair of metal plates fastened to an end portion of each of said shanks, each of said metal plates having a clamping section adapted to receive and retain one of said springs, wherein said clamping section of one of said metal plates has an inwardly pressed bulge and one of said metal plates has an outwardly directed bulge, said bulges being adapted to engage one another when said metal plates are in an untensioned condition.
An installation for the transport of helical-shaped wound springs from a spring winding device to a heat treatment station and subsequently to a transport means, comprising a star turret rotatably driven intermittently about a rotational axis, with a number of shanks which are directed radially outwards from the star turret, and
- a pair of jaws fastened to each of said shanks, at least one of said jaws having a roller secured thereto, said roller being adapted to contact one of said springs.
