Patent ID: 7735297

Claim:
An apparatus for capping bottles comprising: gripping devices for bottles containing products, constrained to a transporter, each of which gripping devices exhibits on a side thereof a gripping means for a corresponding bottle, the gripping means constituted by a vertical portion constrained to an external part of the transporter and a pliers portion which extend towards an outside of the transporter, perpendicular from the vertical portion to which a neck of the bottle is hooked, and on an opposite side of the pliers portion there is provided a hooking-receiving-stabilizing organ for a cap; at least one vertical channel for supplying caps arranged superiorly of the transporter, upstream of a capping zone, and overlying the hooking-receiving-stabilizing organs transiting below the channel, a row of caps being conveyed into the at least one vertical channel, cylindrical bodies of which face towards an upstream end of the transporter, with a head cap of the row of caps being held elastically by a lower end of the supply channel in order to position an internal surface of a relative head such as to intercept a front head of an underlying hooking-receiving-stabilizing organ in order to enable the head cap, in combination with an advancing of the transporter and with a striking and guiding action exerted by the supply channel, to disengage from the supply channel in order to locate in the corresponding hooking-receiving-stabilizing organ, with the relative body facing downwards; at least one pick-up organ, located in the capping zone, operating in phase relation with a corresponding hooking-receiving-stabilizing organ, the at least one pick-up organ being destined to hook and extract the cap present therein, and to position the cap axially in an inlet mouth of the corresponding bottle supported by the gripping device flanking the hooking-receiving-stabilizing organ, in order to perform insertion of the body of the cap in a mouth of the bottle in order to close the bottle.
