Abstract
An apparatus to feed bars is disclosed that comprises a feed device suitable to support a plurality of bars and to make them available to a transfer device. The transfer device is configured to transfer the bars, received from the feed device, toward a delivery zone, and comprises at least one gripping and holding element, configured to take at least one bar from the feed device and to transfer it, by means of rotation around an axis of rotation, toward the delivery zone. The axis of rotation is located, during use, substantially parallel to the longitudinal development of the bars.
Claims11
An apparatus to feed bars comprising a feed device suitable to feed a plurality of bars to a transfer device, said transfer device being configured to transfer said bars toward a delivery zone, wherein said delivery zone comprises at least a support element configured to receive said bar and a positioning element suitable to hold said bar in position, said positioning element comprising a magnet for holding said bar, and said transfer device comprising a transfer disc on which at least one gripping and holding element is installed, provided with a housing seating, said gripping and holding element being configured to take at least one bar from said feed device in order to hold said bar in said housing seating and to transfer said bar by means of rotation around an axis of rotation, toward said delivery zone, and the apparatus further comprising at least a support member with a substantially discoidal shape, selectively rotatable around said axis of rotation, disposed distanced along the axis of rotation with respect to the transfer device and provided with at least a support seating disposed in an angular position substantially mating with that of said housing seating of the gripping and holding element in order to support each bar during its transfer, said axis of rotation being located, during use, substantially parallel to the longitudinal development of said bars.
A method to feed bars that provides to feed a plurality of bars to a feed device, to deliver said bars to a transfer device, and to transfer said bars toward a delivery zone by means of said transfer device, wherein said transfer of the bars is carried out by putting into rotation, around an axis of rotation located during use substantially parallel to the longitudinal development of said bars, at least one gripping and holding element of said transfer device, said gripping and holding element being provided with a housing seating in which at least one of said bars is inserted and held during the rotation, and wherein during the transfer of said bar at least one support member, with a substantially discoidal shape, rotates around said axis of rotation and supports said bar in its support seating disposed in an angular position substantially mating with that of said housing seating and wherein the delivery zone has at least a support element configured to receive at least one of said bars and a positioning element suitable to hold at least one of said bars, said positioning element comprising a magnet for holding at least one of said bar.
