Abstract
Abstract Method and apparatus for the decoration of bottles and the like at high speeds. Bottles are delivered by an input conveyor to a star wheel, which deposits them sequentially into a continuously rotating turret. The turret carries the bottles past a labelling site, where a label carrier strip is pressed into contact with a bottle surface and a label thereby transferred. The shape of the bottle is maintained during labelling by means of inflation of the bottles through an inserted nozzle. The raising and lowering of the inflating nozzle and the flow of inflating air is controlled by special valving apparatus. The motion of the label carrier strip past the labelling site is regulated by the use of rolls on a shuttle slide, which in turn is reciprocated by a second slide driven by a conjugate cam. This results in an increase of the local velocity of the carrier strip during most of the cycle, and a slowing of the strip during the balance. After labelling, the inflating nozzle is retracted from the bottle and the bottle is removed by a second star wheel for further processing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
An improved turret for holding N articles to be labeled, where N is greater than or equal to 1, said turret including article holding means and means for rotating the turret to deliver articles to and away from a labeling site, wherein the improvement comprises apparatus for inflating these articles during labeling comprising: N article inflating members; means for raising and lowering the article inflating members, comprising a N-manifold assembly which provides either a raising signal or a lowering signal to each article inflating member depending on the angular position of said article inflating member with respect to the axis of rotation of said turret; and means for controlling the flow of air through each article inflating member to automatically ensure that such flow occurs only when the inflating member is lowered into an article.
Claim 2
Dependent Claim
135 words
An improved turret for holding N articles to be labeled, where N is greater than or equal to 1, said turret including article holding means and means for rotating the turret to deliver articles to and away from a labeling site, wherein the improvement comprises apparatus for inflating these articles during labeling comprising: N article inflating members; means for raising and lowering the article inflating members, comprising a N-manifold assembly which provides either a raising signal or a lowering signal to each article inflating member depending on the angular position of said article inflating member with respect to the axis of rotation of said turret; and means for controlling the flow of air through each article inflating member to automatically ensure that such flow occurs only when the inflating member is lowered into an article.
Claim 3
Dependent Claim
151 words
A turret for holding articles as defined in claim 1 wherein said raising and lowering means comprises: a stationary valve plate containing pressurized apertures and venting apertures; a valve plate which rotates in conjunction with the rotation of the turret, containing N configurations of ports, which rotating plate contacts the stationary valve plate in a face seal, whereby a port rotating into communication with a pressurized aperture will become pressurized, and a port rotating into communication with a venting aperture will be vented; N actuating cylinders, each having a piston which is coupled to an article inflating member, and each having a top air outlet and a bottom air outlet, whereby pressurization at one outlet and venting at the other will cause a motion of the piston in the venting direction; and for each actuating cylinder, conduits connecting each outlet to a port in a corresponding configuration on the rotating plate.
Claim 4
Dependent Claim
60 words
A turret for holding articles to be labelled as defined in claim 13 wherein the rotating valve plate and the stationary valve plate have circular cross sections, and the N configurations of ports are symmetrically arrayed on the rotating plate, each configuration comprising a port for the top actuating cylinder outlet and a port for the bottom actuating cylinder outlet.
Claim 5
Dependent Claim
26 words
A turret for holding articles to be labelled as defined in claim 3 wherein each configuration of ports further includes a port for article inflating air.
Claim 6
Dependent Claim
56 words
A turret for holding articles to be labelled as defined in claim 13 wherein the stationary valve plate is divided into sectors, such that for each section a given combination of venting and pressurization occurs at the upper and lower actuating cylinder outlets, whereby the article inflating member is appropriately raised or lowered in that sector.
Claim 7
Dependent Claim
112 words
A turret for holding articles to be labelled as defined in claim 5 wherein: the pressurized apertures and venting apertures are annular zones; in any given sector each annular zone has a constant radius with respect to the axis of rotation of the lower plate; and for each configuration of ports in the rotating plate, the port corresponding to the upper air cylinder outlet is at one radius while the port corresponding to the lower air cylinder outlet is at another radius with respect to the axis of rotation of the lower plate, whereby in any given sector each port will contact a venting or a pressurized zone at the same radius.
Claim 8
Dependent Claim
130 words
A turret for holding articles to be labelled as defined in claim 12 wherein said article inflating member comprises a tube carrying an inflating nozzle and containing a duct running from said inflating nozzle to an aperture in the side of said tube, and wherein said means for controlling the flow of air comprises: a source of inflating air; N piston valve assemblies, each containing a central bore through which one of said nozzle carrying tubes may slide between raised and lowered positions, and a passage connecting said source of inflating air to the central bore, located so that said passage will communicate with the aperture on the side of said tube when the tube is in the lowered position, but not when the tube is in the raised position.
