US 2017/0361513 A1 · METHOD AND APPARATUS FOR THE ON-LINE INTERNAL SILICONING OF BOTTLES FOR PHARMACEUTICAL USE

Abstract

Apparatuses and methods for on-line internal siliconing of glass bottles including a baking station for baking the siliconed bottles; wherein a siliconing station includes a support designed to selectively receive one bottle at a time, an injection device facing towards an inlet opening of the bottle, a mobile device for selectively blocking the injector against the inlet opening, a selective feeding device for feeding filtered compressed air and liquid silicone to the injector, the injector provided at the front, towards the support, with a drainage channel communicating with the inlet opening; an emitter to send towards a sensor and through the bottle on the support a beam of electromagnetic radiation; and a control unit to selectively inject into the bottle a mixture of silicone and compressed air and to process a signal emitted by the sensor to control the feeding device and/or a manipulator to discard defective bottles.

Dependent claims

A method for carrying out siliconing of glass bottles for pharmaceutical use, the method comprising:

internal siliconing of the bottle, wherein the internal siliconing includes:
arranging a bottle on a support that maintains the bottle oriented in a predetermined direction;
contacting an inlet opening of the bottle arranged according to the predetermined direction with an injection device;
introducing into the bottle, by the injection device and through the inlet opening, a mixture of liquid silicone and compressed air in which the liquid silicone is present in excess with respect to a predetermined amount to be introduced into the bottle, providing a drainage path for the excess silicone and for the compressed air out of the bottle and through the inlet opening;
and
introducing into the bottle, by the injection device and through the inlet opening, a flow of only compressed air to completely remove the excess silicone through the drainage path by the flow of compressed air.

An apparatus for siliconing of glass bottles for pharmaceutical use, the apparatus comprising:

a siliconing station;
and
a baking station of the siliconized glass bottles, arranged immediately downstream of a forming station of the glass bottles starting from a glass tube by a flame station and an annealing station including an annealing furnace;
wherein the siliconing station includes:
at least a support designed to selectively receive one bottle at a time arranged oriented in a predetermined direction, preferably horizontal;
at least an injection device arranged according to the predetermined direction and so as to be facing towards an inlet opening of a bottle resting on the support;
at least a mobile device to selectively block the at least an injection device against the opening of a bottle arranged on the support;
a selective feeding device to the at least an injection device of compressed air and of liquid silicone, the feeding device being designed to selectively introduce into a bottle present on the at least a support, by the at least an injection device and through the opening;
a mixture of liquid silicone and compressed air in which the liquid silicone is present in excess with respect to a predetermined amount to be introduced into the bottle;
and
only compressed air;
wherein the at least an injection device is provided at the front, towards the support, with a drainage channel for the excess silicone and for the compressed air, the drainage channel being designed to be communicating with the inlet opening of the bottle when the at least an injection device is blocked against the opening of the bottle.
