A gripper (42) for gripping an object (14), intended for a transfer device includes two jaws (64, 66). Each of the jaws includes: a recess (92), and a first clamping portion (94) and a second locking portion (96). The first clamping portion (94) of each jaw (64, 66) of the gripper (42) includes a supporting surface and, when the gripper (42) is closed around an object (14) occupying a predetermined reference position, the supporting surface is intended to engage with a portion of a bearing surface of a radial collar of the object. |

1. A device (10) for transferring objects, said transfer device (10) comprising:
a gripper (42) that that transfers objects, including preforms (14) or containers (16), said objects comprising i) a neck (44) having a distal first end provided with a rim (46) delimiting an opening (48), and a second end provided with a radially projecting annular collar (50) having a bearing face (62), ii) a junction section (60) adjacent the collar (50), and iii) a hollow body (56) extending axially away from the opening (48) of the neck (44) from the junction section (60) to a bottom (58), wherein, said gripper (42) includes at least a first jaw (64), a second jaw (66), and a housing (68) delimited between the first and second jaws (64, 66), wherein when transferring one said object, said housing (68) receives a portion of said object (14, 16), the gripper (42) moves between i) an open position in which said object (14, 16) can be extracted from between or inserted between the first and second jaws (64, 66) to occupy a particular reference position in the housing (68) and ii) a closed position in which, when said object (14, 16) is present, said jaws (64, 66) cooperate with at least a portion of said object (14, 16) to retain said object (14,16) in said particular reference position, the first and second jaws (64, 66) each include, respectively: i) a first, clamping portion (94) that, in the closed position of the gripper (42), applies a radial clamping force to the junction section (60) of said object (14, 16), the radial clamping force retaining said object (14, 16) in said particular reference position in the housing (68), and ii) a second, locking portion (96) that, in the closed position of the gripper (42), is in axial abutment with a top surface of the rim (46) of the neck (44) of said object thereby axially locking said object in said particular reference position, and iii) a recess (92) that axially separates the first and second jaws (64, 66), the recess (92) being open radially, and the first, clamping portion (94) of each jaw (64, 66) includes a support face (98) that, in the closed position of the gripper (42) with said object (14, 16) occupying said particular reference position, cooperates with an adjacent portion of the bearing face (62) of the annular collar (50). |
