Abstract
A method includes the following steps: aligning a measuring head with an aerosol container, without relative speed between the two, lowering and centring the head; lowering a measuring device and taking the corresponding measurement at different points of the perimeter of the opening; rotating the measuring device in relation to the container; removing the head, transmitting the data, and removing the unsuitable containers, and a device for performing the method includes a head support having an axial movement device, a centring element; a support for the measuring device, an assembly of measuring arms provided with probes, an arrangement for returning to a rest position, at least one measurement reader, and a rotating device for rotating the measuring device or head.
Claims8
A device for inspecting and measuring the mouthpieces of aerosol containers by inspecting and measuring a join between a hole in a dome of an aerosol container and a corresponding valve holder cup as to dimensions of a continuous or discontinuous seam produced by plastic deformation of said join, carried out continuously along a packaging line for aerosol containers said device comprising a measuring head having axial relative displacement capability with respect to an aerosol container which has to be measured, said measuring head comprising:
- a centering element which is located in a lower part of the measuring head, and said centering element having a central interior cavity;
- and
- a measuring gauge support located above the centering element;
- a device for measuring the mouthpieces to provide a measurement, provided with an arrangement for axial travel in respect of the aerosol container axis;
- wherein the centering element is connected with the measuring gauge support by an elastic centering element having relative axial displacement capability with respect to each other in such a way that when said centering element rests on the aerosol dome in axial displacement thereof, the centering element stops displacement thereof and the measuring head continues lowering movement thereof, against the action of the elastic arrangement of said centering element, up to a predetermined position at which the measurement has to be taken;
- a device for controlling the measuring gauge support axial travel from the position where the centering element rests on the aerosol dome to the position in which the measurement has to be taken;
- wherein the measuring gauge support is provided with a support for a set of measuring arms, wherein said measuring gauge support is provided with a set of axle-bearing elements arranged radially, which house spindles of each of the measuring arms for measuring a distance from a central axis of the container to a periphery of the hole in the dome simultaneously at different points;
- and
- wherein the device rotates relative to the container to obtain the measurement along a complete circle surrounding the container.
