  • the centering and screwing head 120 of the device 10 is brought into a position above the filler neck 105 by moving the support arm.
  • the centering and screwing head 120 is then lowered into the position shown in FIGS. 1 and 2, in which the centering ring 62 with its conical inner wall surface 63 engages over the peripheral edge 110 of the barrel filler neck 105, the conically running inner wall surface 63 engaging the arcuate section 114 of the edge bead 111 of the filler neck 105 comes to rest (FIG. 3).
  • This distance H enables the screw cap 115 to be lifted when the screw cap 115 is unscrewed from the thread of the barrel filler neck 105 in such a way that when the centering and screw head 120 is raised further while simultaneously performing a rotary movement of the screw cap 115 by means of the wrench engaging in the screw cap 115 140 when the drive device 150 is started up, the screw cap 115 is unscrewed from the thread of the barrel filler neck 105.
  • the vacuum generating device is put into operation, so that a vacuum is generated in the interior of the cylindrical hollow body 60, which holds the screw cap 115 on the wrench 140 or through the sealing surface 68 and the laterally projecting and circumferential wall surface 115a of the screw cap 115 enables (Fig. 3).
  • This wrench 140 has a head-like design on the bottom to create a contact surface for the screw cap 115.
  • the centering and alignment of the centering and screwing head 120 or the centering ring 62 on the circumferential edge of the barrel filler neck 105 takes place through the interaction of the inner wall surface configuration of the centering ring 62 and the configuration of the circumferential edge 110 of the barrel filling neck 105.
  • the centering and screwing head 120 in With respect to its longitudinal axis, which is arranged in the support frame 30 or the support bracket 31 and is spring-loaded, the centering ring 62 is automatically aligned on the barrel filler neck 105, even if this should not assume a vertical position relative to the barrel cover plate 101 of the barrel 100. If the screw cap is lifted from the thread of the barrel filler neck 105, then the centering and screwing Head 120 returned by means of the helical compression spring 42 in its vertical starting position according to Fig.1 and 2. During the unscrewing process of the screw cap 115, the wrench 140 is operatively connected to the screw cap and is rotated by means of the drive device 150 via the drive shaft 53.
  • the screw cap 115 falls off and can be transported away. If the centering and screwing head 120 has assumed an inclined position for the unscrewing process, that is to say it has been tilted, then the centering and screwing head is automatically aligned to the vertical by means of the screw compression spring 42. The unscrewing pressure is absorbed by the helical compression spring 56 when the screw cap 115 is raised. When a screw cap 115 is screwed into the thread of a barrel filler neck 105, the helical compression spring 56 presses the wrench down with the screw cap 115 sucked in by vacuum.
  • the force of the helical compression spring 56 is dimensioned such that the thread of the screw cap 115 and the internal thread 107 of the barrel filler neck 105 are not damaged.
  • the wrench 140 is rotated further in order to ensure that the screw cap 115 is also completely unscrewed from the thread of the barrel filler neck 105, ie the drive of the wrench 140 is maintained until the screw cap 115 has lifted off the barrel filler neck 105.
  • the centering and screwing head 120 of the device 10 is moved into the area of the barrel filler neck 105, the cylindrical hollow body 60 with its centering ring 62 by means of the helical compression spring 61 downward in the direction of the barrel filler neck 105 is pressed.
  • the centering ring 62 is pressed against the peripheral edge 110 of the barrel filler neck 105.
  • the hollow body 60 also lowers with the centering ring 62, the drive shaft 53 then rotating with the wrench 140 when the drive device 150 is started up, the wrench 140 being under the tension of the helical compression spring 56.
  • the centering and screwing head 120 adapts to the respective position of the barrel filler neck 105, even if the longitudinal axis of the barrel filler neck 105 does not extend to the vertical.
  • the outer centering element 130 is pressed against the barrel filler neck 105, the ring portion 65 of the inner wall surface 63 of the centering ring 62 coming to rest on the attachment edge 112 of the edge bead 111 of the barrel filler neck 105 or being pressed against this annular attachment edge 112.
  • the main and the fine alignment of the centering and screwing head 120 then takes place through the interaction of the specially designed contact surface 64 of the inner wall surface 63 of the centering ring 62 with the special design of the peripheral edge 110 of the barrel filler neck 105, and in particular with the attachment edge 112 of the barrel filler neck 105 (Fig.3).
  • the lateral alignment of the centering and screwing head 120 then takes place by means of the conically tapering inner wall surface section on the circular section 114 of the circumferential edge 110 of the barrel filler neck 105, while fine-centering and.
  • Matching to the filler neck 105 takes place.
  • the vertical position to the barrel filler neck 105 is determined and defined by the vertical ring surface 69 of the inner wall 63 of the centering ring 62.
  • the wrench 140 which is in engagement with the screw cap 115, is rotated for the screwing-in process, the screwing-in process being carried out in such a way that First of all, there is a short left turn so that the screw cap 115 engages in the beginning of the internal thread 107 of the barrel filler neck 105. Then the direction of rotation of the drive shaft 53 is changed with the wrench 140 and the screw cap 115 is then screwed into the thread of the barrel filler neck 105 by a clockwise rotation.
  • the centering and screw head 120 with the drive device 150 is arranged for free movement in the spring 42 or suspended from it.
