Abstract
A device and a method for forming hollow cylindrical bodies. The device has a plurality of stations. A tool is allocated to each station. The tools are arranged on a common carrier. The tool can be moved between two reversing positions via a main drive. This reciprocating movement is executed intermittently. One of the two reversing positions forms a rest position in which the tool carrier stops in a rest phase. While the tool carrier stops in a rest position in the rest phase, a transport device transports the bodies from one station to the respective next station.
Claims12
A device (10) for forming hollow cylindrical bodies (11), the device (10) comprises:
- a common tool carrier (14) including a plurality of stations (12) in operative arrangement along a circular orbit and comprise, respectively, one tool (13), wherein the tools (13) are in operative arrangement on the common tool carrier (14),
- a main drive (15) in operative arrangement with the common tool carrier (14) for generating an intermittent reciprocating movement (H) of the common tool carrier (14) between two reversing positions (UA, UB) thereof,
- a transport device (23) in operative arrangement with the common tool carrier (14), the transport device (23) operatively disposed for transporting the hollow cylindrical bodies (11) between the stations (12) and comprises a rotating part (24) with a plurality of holding means (28) for respectively holding one of the hollow cylindrical bodies (11) arranged along an orbit (K),
- the transport device (23) comprising a separate rotary drive (30) in operative arrangement with the rotating part (24) for generating an intermittent movement of rotation of the rotating part (24), and,
- a control unit (19) in operative arrangement with the main drive (15) and the separate rotary drive (30), the control unit (19) disposed to control the main drive (15) and the rotary drive (30) in such a manner that the intermittent movement of rotation of the rotating part (24) is performed as long as the tool carrier (14) is stopped in one of the reversing positions that is a rest position (UA).
A method for operating a device (10) for forming hollow cylindrical bodies (11), the device (10) comprises a common tool carrier (14) with a plurality of stations (12) that are arranged along a circular orbit and comprise, respectively, one tool (13), wherein the tools (13) are arranged on the common tool carrier (14), a main drive (15) in operative arrangement with the common tool carrier (14), a transport device (23) including a rotating part (24), a separate rotary drive (30) in operative arrangement with the rotating part (24), the method comprises the following steps:
- initiating an intermittent reciprocating movement (H) of the tool carrier (14) between two reversing points (UA, UB),
- transporting the hollow cylindrical bodies (11) by the rotating part (24) between the stations (12) along a circular orbit (K),
- moving the tool carrier (14) into a rest position (UA) via the main drive (15) before starting of an intermittent rotating movement of the rotating part (24) and stopping the tool carrier (14) in the rest position (UA), —
- subsequently, initiating the intermittent rotating movement of the rotating part (24) via the rotary drive (30), and,
- starting the reciprocating movement (H) of the tool carrier (14) out of the rest position (UA) only after the intermittent rotating movement of the rotating part (24) is completed.
