A feeder mechanism for feeding mechanical fasteners, such as rivets, screws, bolts and similar fasteners, as well as to a robot end effector comprising such a mechanism and a robot being equipped with such an end effector. The feeder mechanism includes a transport means for transporting mechanical fasteners and a stopping and aligning unit with a stopping plate to decelerate transported fasteners.

A magazine for storing elements which each have a shaft and a head. The magazine includes a cylinder defining a shell surface in which is formed a helical-shaped groove. The shaft of each element to be stored can be inserted into the groove while the head of each element protrudes outward radially over the groove. The head of each element can be impacted in the peripheral direction by a suitable carrier in order to move the elements through the groove one after the other to an outlet end of the groove where the elements are ejected individually.

A tool for repeatedly feeding individual fasteners from a fastener supply includes a receiver, a guide, a flexible, linear thruster, an electric drive, an activator, and a feeder with a dispenser. The guide extends along a curved guide track from the receiver into the feeder and terminates at the dispenser. Along the guide track the guide has a substantially constant opening cross section radially defined by a guide element relative to the guide track to guide the fasteners directly adjacent to one another along the guide track. The thruster extends from the receiver into the guide and has an external cross section adapted to the opening cross section and configured to be moved in a guided manner by the drive in the guide along the guide track. The drive is coupled to the activator and moves the thruster in the direction of the dispenser when the activator is actuated.

A fastening device is equipped with a stocker. The stocker has a circular arcuate shape which is curved in a horizontal plane, and accommodates fastening tools in a state of being aligned in a row. The fastening tool that is positioned at a most downstream side of the stocker is supplied to the receiving site by an unloading and supplying device. Furthermore, the fastening tool supplied to the receiving site is screw-rotated by a screw-rotating device that is displaced toward the fastening tool.

The invention relates to a feeding machine for washers allowing a correct placement of eyelets in laminar bodies, such as textile elements, wherein said feeding machine includes a ramp for moving the washers from a higher height to a lower height, a plurality of detectors for detecting a washer which are arranged in different segments of a length of the ramp, configured to detect the presence of each washer; and a plurality of linear actuators arranged along the length of the ramp, said actuators being connected to stops which are configured to block the passage of the washers along the ramp. The feeding machine also includes a control electronics connected to the linear actuators and to the detectors for detecting a washer, said control electronics being configured to control the feeding of the washers along the ramp.

A method of processing O-rings in an automated mass production system includes: (a) advancing an O-ring retainer toward a loading position in alignment with an output end of a feed device; (b) discharging a leading O-ring from the output end in electronic synchronization with advancement of the O-ring retainer to the loading position to initiate loading of the O-ring into the retainer prior to the retainer arriving at the loading position; (c) after loading the O-ring into the retainer, advancing the retainer away from the loading position toward an unloading position; and (d) moving an end effector in electronic synchronization with advancement of the retainer to the unloading position to synchronize arrival of the retainer at the unloading position with arrival of the end effector at a pick-up position in alignment with the O-ring at the unloading position for pick up of the O-ring by the end effector.

A concrete nailer has a cutout defined by a magazine. The cutout is disposed proximate the drive track of the concrete nailer and provides the concrete nailer with sufficient reach to perpendicularly nail a complete range of U-shaped channels or track available to the job site against concrete, even though the magazine accommodates both long and short nails. The concrete nailer has the added ability to nail thick boards like 2×4's to concrete.

A self-piercing rivet escapement mechanism for a rivet setting machine includes a self-piercing rivet track in which self-piercing rivets are receivable. A first resiliently biased jaw is biased towards a closed configuration in which the first resiliently biased jaw retains self-piercing rivets in the self-piercing rivet track. The first resiliently biased jaw is moveable to an open configuration in which a self-piercing rivet can escape the self-piercing rivet track. The first resiliently biased jaw is configured to move from the closed configuration to the open configuration upon exertion of a load upon the first resiliently biased jaw.

A device for the transport of singled objects comprising a first tube section, delimiting a loading channel from a rear aperture to a front aperture, a loading aperture for the insertion of the singled object in the loading channel, a second tube section connected to the rear aperture of the first tube section and delimiting a guide channel, a thrust generator suitable to generate in the loading channel a thrust in the transport direction, a transport support suitable to accommodate the object and arranged in the loading channel in such a way as to be launched in the transport direction along the guide channel and a rebound device positioned in the guide channel to make the transport support bounce, causing the release of the object from transport.

Disclosed is a cartridge-type rivet feeding mechanism of a flow drill screwing device including a rivet box, a magazine for storing rivets from the rivet box, a rivet pulling mechanism including a rivet pulling block, a rivet pulling block guide housing and a linear driving unit connected with the rivet pulling block, a blowing mechanism including a curved connecting tube and a third air inlet, the rivet pulling block is defined with a T-shaped through hole capable of accommodating a rivet and configured for transferring the rivet from the first connecting tube to the second connecting tube. The first air inlet and the second air inlet are both configured for introducing compressed air to push the rivet to move towards the riveter head.
