Complete Specification for the invention entitled: TIOT EMBOSSING MACHINE FOR PLASTIC ARTICLES The following statement is a full description of this invenilion including the best method of performing it known to me:.
I
Signature of TO .wcs applicant or Australian (Signature) attorney THE COMMISSIONER OF PATENTS This form must be accompanied by either a provisional specification (Form 9 and true (opy) or by a complte specification (Form 10 and true copy).
2. -2- This invention relates to a device for embossing plastic containers for example in order to place a permanent code on the container.
The marking of containers for example for the purpose of coding corresponding to the container contents, is ;usually done by ink machines. Such inking process is messy and consumes ink. Further, the machines tend to be complicated and subject to some maintenance.
The present invention provides in one broad form a hot embossing machine for plastics articles comprising: a stamp holder including, or adapted to hold, a heat conductive stamp including an exposed embossing face; a heat source in heat conductive contact with the stamp holder; and a feed device being, or adapted to be, positioned opposite the stamp holder with a resilient drive means adapted to continuously provide a moving contact point :acting on a passing article at a point adjustably separated from the embossing face and and positioned generally perpendicularly therefrom so that articles of ::.similar cross section introduced one by one \o an entry side of the feed device will be simultaneously moved past, j* "and pressured against, the stamp by the drive means Sthereby bringing the article into temporary prgssured contact with the heated stamp so as to emboss tie article.
Preferably the machine is attached to, or made integral with, a conveyor for feeding articles in a common orientation into the entry side of the machine and fo :receiving them from an opposite exit side of the machine.
S pIt is further pre =rred that the feed device is a driven continuous belt including in its path a straight section defined between two guide turfaces and being generally parallel to the embos ing ace. The belt can be resilisatly displaced at the contact point so as to provid the described pressuring of each article aainst 7 *r S'."silr crs scinitoueonbyneoannryi (S.gnature of Declarant THE COMMISSIONER OF PATENTS.

the stamp.
The machine is well suited to round sectioned articles which are rolled past the stamp, the point contact at the tangent of the article and the stamp being stationery during the rolling motion, the rolling motion being effected by the movement of the drive means.
The machine is also well adapted for non circular sectioned articles, such as square articles. In such cases the machine benefits from the inclusion of a mechanism at the entry side of the device for providing the articles in a spaced apart relationship at the stamp, for example by a pneumatic gating system or variable speed wheel, and by fitting the stamp into the surface of a rotary device such as a wheel or quadrant so as to effect a rolling of the embossing face against the article.
Alternatively a guide rail may be provided either side of the stamp holder and the drive means adapted to pass the articles past the stamp in a spaced apart fashion, the stamp being reciprocal toward and away from the articles and being so reciprocated toward and away from articles when they are sensed to be in a predetermined correct position.
As an example only, the following describes preferred features of the invention with reference to the drawings 25 in which Fig. 1 is a perspective view of an assembled coding machine in accordance with the invention; Fig. 2 is an inverted perspective view showing detail of the drive device of Fig,. 1 Fig. 3 is a perspective view of an alternative embodiment of the device of Fig. 1 particularly adapted for embossing square articles; and Fig. 4 is a view similar to Fig. 3 of another alternative embodiment for square containers.
A conveyor belt 1 delivers a continuous supply of articles 2 at the entry side 3 of the heat embossing device 4. The same belt 1 removes the articles after the exit from side 5 of the embossing machine. The i t I "i Ii :1 4 articles 2 are maintained on the belt 1, and guided into the machine 4, by opposed approximately parallel rails 6.
The embossing machine 4 includes two fixed, opposing components one either side of the belt I being a heating unit 7 and a feed device 8.
The heating unit 7 releasably fixes a metal stamp 9 with its embossing face exposed at one side of the conveyor track. The stamp 9 is heated electrically by heating elements within the unit 7.
The feed device 8 drives a continuous drive belt about a generally triangular track defined by two guide rollers 11 and a drive roller 13 within the device 8. The guide rollers 11 define a straight path of the drive belt approximately parallel to the belt 1.
The positioning of the feed device 8, or more S particularly the guide rollers 11, is, or are, adjustably positioned toward or away from the stamp 9. When *correctly distanced from the stamp 9 the front portion of the drive belt 10 is resiliently pushed out of its defined 20 straight line as each article 2 is moved through the embossing machine 4. Thus each article 2 is pressured against the stamp 9, which tends to cause zero relative movement between the article 2 at its contact point and the stamp 9, and thus a rolling of the article 2 through 25 the embossing device 4. As each article 2 is rolled past the stamp 9 the information on the embossing surface of the stamp is melted into the article 2.
The generally triangular track of the drive belt can be of different configurations, e.g, a parallel track defined between a single idle roller 11 and a single drive roller 13.
Detail of the feed device 8 is more clearly shown in Fig. 2. The feed device 8 includes a platform 12 supporting a drive wheel 13 on one side of the plate 12 and an electric drive motor 14 on the opposite side. The continuous drive belt 10 extends about the driving wheel 13 and a continuous guide 11 made from low friction material.
The platform 12 and attached hardware is adjustably I i l i h J positioned by rigid attachment to a fastenj :g plate The fastening plate 15 is fixed to the conveyor system via fixing holes 16. The plate 12 is attached to the plate via the shouldered stud 17 and nut 18. The relative position, in the direction toward and away from the device 4, is adjusted by knob 19 which is threadably attached to structure accepting the stud 17.
The Fig. 3 embodiment is particularly adapted for square articles. The endless drive belt 10 includes a number of equally spaced apart protrusions 20 forming small gates which correctly orientate square articles as they pass by the embossing stamp 9. The embossing stamp 9 is in fact a wheel which revolves as the square article passes by the stamp 9 while being held rotatably still.
Fig 4 is an alternative embodiment suited to flat or i square containers. The drive unit 8 is the same as that shown in Fig. 1 while the heated stamp 9 is carried on a pressure bar 20 which is moved in an elliptical path by eccentric drives 21. Containers 2 are fed spaced apart by 20 a pair of gates 22, the gates 22 belt 1, drive unit 8 and eccentric drives 21 are all co-ordinated to stamp the centre of each container face which aligns adjacent the V. heater unit. The elliptical path of the pressure bar and the connected stamp 9, gives the required pressure of 25 the stamp against the container for the required melting time without bringing container 2 to a stop.
Alternatively the stamp 9 is at an end of a ram ccntrolled by a sensor to reciprocate the stamp outwardly and then inwardly, to engage and emboss each passing container 2.
