  • Patent number: 11643278
    Abstract: A screw forwarding device for a screw feeder includes a base plate, a vibration mechanism including at least one spring and a vibration motor connected to the at least one spring, and a rail for receiving screws. The rail is connected to a first end of the at least one spring and the at least one spring is arranged at an oblique angle to the rail. The screw forwarding device further includes a fastening mechanism for rigidly connecting a second end of the at least one spring to the base plate, whereby a movement path of the vibration mechanism, during a use of the screw forwarding device, defines a plane of movement. The base plate is oriented substantially parallel to the plane of movement defined by the vibration mechanism.
