Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for decorating articles having a partially conical surface.

[0002]

2. Description of the Related Art Decoration of conical surfaces of articles such as colorings, designs, photographs, etc. (hereinafter, referred to as decorations for simplicity of description) is performed in various situations. Here, the article does not have a whole conical shape, but a conical part and a cylindrical part, and the conical part must be decorated. Articles are included. One method of decorating the conical surface of such an article is to use a stamping foil. This pressed foil is also called an embossed foil or a transfer foil, such as a pressed foil. DE 39 31 5
56 C2 discloses one embodiment of such a method. A plurality of decorations are continuously arranged on the stamping foil, and the stamping foil is unwound from a feed roll and supplied to a stamp station for making contact with the decorative article. In this case, the decoration is transferred from the foil to the article surface by a stamp or an applicator roller (hereinafter, referred to as a stamp roller for simplicity of description). The surface of the stamp roller is cylindrical, and the roller can be freely driven by appropriate driving means. The foil is wound and guided by a direction changing roller interlocking with the feed roller. The redirection roller is disposed upstream of the stamp station in front of the foil in the traveling direction. The foil is fed from the deflecting roller to the stamp station, at which time the deflecting roller has been moved to a position that has been correctly adjusted to the rotational angle position of the article from which the decoration is to be transferred from the foil.

[0003] In this method, the direction changing roller continuously linearly moves by a distance equal to the difference between the linear movement path of the stamp roller and the arc when the conical surface of the decorative article is developed. At the same time, the direction changing roller is always oscillating so as to correct the linear movement of the stamp roller with respect to the opening angle when the conical surface of the article is deployed in an arc shape. In a preferred embodiment of the apparatus for performing the method, the direction changing roller is mounted on a fixed member rotatable about a longitudinal axis. The securing member is further connected to the adjustment platform by a pivot axis. The platform is disposed on the fixed base member by a drive for linear movement. The fixing member includes a detection element slidably guided on a surface of a guide device mounted on the fixed base member. Therefore, as a design configuration, a plurality of structural members that cooperate slidably with each other and have a large degree of mechanical friction are required. Manufacturing such individual parts increases the manufacturing cost of the device.

Further, a stamping foil supply device for a stamp device is disclosed in German Published Patent Application (DE-AS) No. 2721.
As disclosed in U.S. Pat. No. 908, decoration is performed using a stamping foil on the circumferential surface of an article such as a TV case having the shape of a flat-headed pyramid. The stamping foil is supplied from a feed roll which is axially movable and is substantially parallel to the stamp or applicator roller of the stamp station. Before the transfer to the corresponding surface of the decorative article, a guide roller guides the stamping foil between the feed roll and the stamp roll. The guide roller is movable in parallel and imparts tension to the stamping foil,
Further, it is arranged rotatably about a horizontal axis perpendicular to the decoration surface of the article. In order to guide the stamping foil when the stamping foil moves from the feed roll to the stamp roll, a guide roller that can be linked with the stamping foil feed roll is formed into a floating roller. In other words, the guide roller is movably mounted, and automatically adapts in a stepwise manner according to the operating condition determined by the relationship between the stamping foil and the surface of the decorative article. In this case, since the decorative article is in the shape of a flat-headed quadrangular pyramid and has a plurality of planes, the floating roller moves in accordance with a change in the tension of the stamping foil. However,
For example, the situation is different when handling an article having a conical surface, such as when handling an article in the shape of a truncated cone. Such articles include, for example, liquid cans.

In the case of a method in which a moving material web is guided laterally along a part of its travel path, German Offenlegungsschrift (D)
E-OS) As disclosed in No. 20 06 571, the web is fed along a main web guide roller. The main web guide roller oscillates in a moving plane away from the neutral position. In the neutral position, the main web guide roller is perpendicular to the desired path of the web. When the web moves on the surface of the main web guide roller, a lateral position of the web is detected at a detection position upstream of the guide roller. The main web guide roller swings away from the neutral position of the main web guide roller in a direction to appropriately correct the deviation of the web from the desired moving path. After passing the main web guide roller, the web turns in the direction of the discharge web guide roller. Then, the web is separated from the discharge web guide roller at a position adjacent to the same plane as the detection position and perpendicular to the moving surface of the main web guide roller. During the period when the main web guide roller swings, the discharge web guide roller is held parallel to the main web guide roller.

Finally, British Patent No. 1 282 58
No. 8 discloses an apparatus for spirally winding a cord-like material around the surface of a cylindrical or frustoconical article.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a decoration device and a method according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a plan view of a device 10 for transferring a decoration to a conical surface of an article. The device comprises a stamp or applicator roller 1 having a cylindrical surface 14.
2 is comprised. This applicator roller can be heated and driven by the first drive means 16 for proper positioning. The drive communication between the drive means 16 and the rollers 12 is shown at 18.

Referring now to FIG. The same members as those in FIG. 1 are denoted by the same reference numerals. The article 24 has a substantially conical surface 20 on which the decoration is transferred in strip form from the stamping foil 22 of FIG. The article 24 is pressed against the cylindrical surface 14 of the roller 12. In FIG. 1, the article 24 is located below the roller 12 and is indicated by a dotted line. The conical article 24 is pressed against the cylindrical surface 14 of the roller 12 via a bus bar 26. The article is supported by holding means which can be driven by the third driving means 28 shown in FIGS. The drive connection between the drive means 28 and the article 24 in the holding means is indicated by the arrow 30 in FIGS.

During operation of the apparatus, the foil 22 is unwound from a feed roll (not shown), and the direction changing guide roller 32 is rotated.
It is wound up. The direction changing guide roller is interlocked with the feed roller, and is connected to the second driving means 34 in FIG.
As a result, it moves along the bow-shaped guide means 36. The arcuate guide means 36 is disposed flush with the common bus bar 26 between the cylindrical surface 14 of the roller 12 and the conical surface 20 of the article 24. Said plane is perpendicular to the drawing of FIG. 2 and is shown in FIG. The radius of curvature of the guide means 36 is indicated by R in FIG. 1 and the center of curvature 40 of the guide means is the common bus 2 of the stamp roller 12 and the article 24
6 is located in the central area. For this reason, at the start of the stamping operation for transferring the decoration from the foil 22 to the surface 20 of the article 24, the reference numeral 4 in FIG.
The foil 22 can be supplied to a stamping station indicated at 2. That is, the shaft 44 of the roller 12 shown in FIG.
And the foil can be supplied perpendicular to the common bus 26.

The first driving means 16, the second driving means 34 and the third driving means 28 are connected to an electronic control means 46 shown by a schematic block in FIG. Guide roller 32
The control means 46 turns off the driving of the roller 12 via the first driving means 16 during the stamping operation so that the decoration is always correctly transferred to the article 24 by appropriately adjusting the second driving means and the second driving means. The guide roller 32 is driven by 34 and the stamp station 42 is driven by the third driving means 28.
The holding means for holding the article at is driven. Foil 22
During the stamping operation of transferring the decoration from the to the article 24, the stamp roller is not driven by the corresponding drive means, but is driven only by frictional engagement with the article. Accordingly, the driving means 16 is connected to the foil 22 of the stamp station 42.
It only positions the roller 12 with respect to. With such a configuration, the movements of the guide roller 32 and the foil 22 are not excessively restricted, and therefore, the decoration is accurately transferred to the article regardless of the size and / or shape. It is possible to do.

The three-dot chain line in FIG. 1 shows the intermediate position of the guide roller 32 on the arcuate guide means 36 and the corresponding position of the foil 22 for correctly transferring the decoration to the circumferential portion of the conical article 24.

As can be seen from FIG.
Are shown as thin lines, which intersect at a common intersection 48. Bow guide means 36
Has a portion 50 that is at least substantially parallel to the common generatrix 26 of the roller 12 and the conical or frustoconical article 24. The arc-shaped guide means is provided at the intersection 4 of the genera
8 extend from the parallel portion in a direction away from the parallel portion 8.

Thus, as can be seen from the above description of the apparatus and method of the present invention for transferring a decoration to an article 24, the first drive means 16 drives the roller 12 to accurately register the roller with the decoration of the foil 22. I do. When the positioning operation is performed, for example, the first driving unit is separated from the roller 12 by turning off the driving unit. As a result, the roller 12 is not driven by the first driving unit 16. Next, the roller 12 is further driven along the circumferential surface of the decorative article only by frictional engagement with the decorative article. The guide roller 32 and the foil 22 move relative to the stamping station 42 along the arcuate guide means 36, but the arcuate shape prevents the foil from unnecessarily curving or twisting as it passes through the station 42. The guide means 32 is disposed on a plane formed by a common generating line of the cylindrical surface of the roller 12 and the conical surface 20 of the article 24. Therefore, foil 2
2 moves in the plane towards the station 42. That is, it moves into the stamp gap formed by the common bus between the roller 12 and the conical article 22 in accordance with the rotational movement of the article 24 transferring the decoration from the foil 22.

When the guide roller 32 is in a position parallel to the bus bar 26 on the guide means 36, the foil 22 is supplied to the stamp station 42 in a state perpendicular to the bus bar. Thus, depending on the movement of the guide roller 32 along the guide means 36, the foil 22 is supplied to the station 42 at various angles with respect to the generatrix. This angle corresponds to each rotational angle position of the decorative article 24, that is, each part when the conical surface 20 of the article 24 is developed.
