US 2021/0179310 A1 · MACHINE AND METHOD FOR LABELING CONTAINERS

Abstract

A machine for labeling containers conveys, along an advancement direction, the labels to be applied, which have a transfer drum which is adapted to bring individual labels into contact with corresponding containers which are supported by a conveyor. A spraying assembly faces the transfer drum and is adapted to apply glue on the labels; the spraying assembly includes at least one spray gun which has a plate-like glue dispensing body which faces the lateral surface of the transfer drum and is passed through by a plurality of dispensing ports, which are arranged mutually spaced apart along at least one row which extends substantially parallel to the axis of the transfer drum; a controller is configured to actuate a slowing of the advancement speed of the labels with respect to the spray gun before actuating the activation of the spray gun for the application of the glue on the labels.

A machine for labeling containers, which comprises conveyor means for conveying, along an advancement direction, the labels to be applied, said conveyor means being provided with a transfer drum which is adapted to bring individual labels into contact with corresponding containers which are supported by a conveyor, a spraying assembly facing said transfer drum and being adapted to apply glue on the labels, wherein said spraying assembly comprises at least one spray gun which has a plate-like glue dispensing body which faces a lateral surface of said transfer drum and is passed through by a plurality of dispensing ports, which are configured to connect an inside of said spray gun to an outside and are mutually spaced apart along at least one row which extends substantially parallel to an axis of said transfer drum, in order to enable the application on the labels of at least one line of glue spots which extends transversely to the advancement direction of the labels, control means being provided which are functionally connected to said conveyor means and to said spray gun and being configured to actuate a slowing of an advancement speed of the labels with respect to said spray gun before an activation of said spray gun for the application of the glue on the labels.

A method for labeling containers, which comprises the steps of:

conveying at least one label by way of a transfer drum at a first advancement speed,
substantially upon arrival or prior to the arrival of at least one portion of said at least one label substantially at a spray gun which faces said transfer drum, slowing the first advancement speed of said at least one label in order to bring it to a second advancement speed which is lower than said first advancement speed,
applying at least one line of glue spots to said at least one label by way of said spray gun,
increasing the advancement speed of said at least one label until said advanced speed returns to said first advancement speed,
bringing, by way of said transfer drum, said at least one label with the glue applied into contact with a corresponding container.
