Disclosed is a cam curve design method for a cap screwing machine based on a multi-objective method, belonging to the technical field of cap screwing machine cam design. The present disclosure is to solve the problem that the conventional method for redesigning the cam curve cannot optimize the parameters according to the degree of importance such that the operating stability of a cam mechanism is poor. The method comprises: acquiring key point data determined for realizing the functions of a cam of the cap screwing machine; performing dimensionless processing on the key point data to obtain a dimensionless time T and a dimensionless displacement S; writing an n-order polynomial fitting cam curve displacement function, manually interpolating local control points, and obtaining a polynomial fitting cam curve expression and chart in combination with the constraints of key point displacement by using a least squares method; and selecting cam curve optimization objectives and setting weight coefficients to construct an optimized cam curve. The present disclosure is used for the design of a cam curve.

The invention relates to a capping machine comprising a protected area from impurities, an unprotected area divided from the protected area by a parting wall, and an operating unit. The operating unit includes a container support element arranged in the protected area, an operating head arranged in the protected area and configured to apply one capsule on the relative container, a motor assembly arranged in the unprotected area and configured to drive motion of the operating head, a torque control head between the motor assembly and the operating head, and an annular bellows element coaxial with the vertical axis and within the protected area and one opposite axial end crossed in a sealed manner by an output shaft of the torque control head. The torque control head is arranged above the parting wall in the unprotected area and the output shaft crosses said opening and the entire bellows element.

An apparatus for capping containers includes at least one capping head which is moveable between a position for picking up a cap and a position for applying the cap at a neck of a container, the grip element defining a receptacle for the cap and component for the removable retention of the cap within the receptacle. A second motor component is provided to actuate the movement of the grip element in an axial direction. The apparatus also includes a control and actuation unit functionally connected to the first and second motor components and is configured to receive in input a number of data items. The control and actuation unit is configured to actuate the first and second motor components as a function of the variation of the value over time of the number of data items.
