Definitions

  • the present invention relates to an apparatus and a method for applying decor adhering to a film to an object.
  • the document EP 0 573 676 B1 discloses the use of a support with "release” property for applying color decoration to a substrate by first applying lacquer and optionally dye to a support with "release” property. Thereafter, a partial crosslinking of the paint is carried out. Subsequently, the partially crosslinked varnish, optionally including the dye, is transferred to the substrate to be decorated or varnished, and complete crosslinking of the varnish takes place.
  • Document EP 1 053 793 A1 discloses a method of applying paint and decor to an object by means of a film having a "release” property, wherein an adhesive layer is applied to the paint and the décor of the "release” film , When the layers are applied to the object, the adhesive layer is in direct contact with the object. Also known from the prior art is an apparatus for applying film-adherent decoration to an object by means of "release” technique.
  • the known devices have the disadvantage that the film can only pass through the device at a speed of less than 5 meters per minute, so that no wrinkling and / or shrinkage of the film occurs and the decor can be removed from the film as intended and on the object can be applied.
  • an object of the present invention to provide an apparatus and method for applying film-adherent décor to an object which enables a high rate of passage of the film through the apparatus without the film folding, blistering or shrinking.
  • a device of the type described which comprises a heating roller for preheating the film, an at least bidirectionally movable adjusting roller, which is arranged next to the heating roller, for adjusting the size of the contact surface of the film with the heating roller, and means for Detaching the decoration from the film preheated by the heating roller onto the object.
  • the processing speed of the film ie, the speed of passage of the film through the apparatus, depends, inter alia, on the contact area of the film with the heat roller and the temperature at which the decoration is peeled off the film. Basically, it can be assumed that the larger the contact surface of the film with the heating roller, the faster the film can pass over the heating roller. If there is only a small contact area between the heating roller and the film, the film should pass through the heating roller only at a low speed. In addition, the height of the temperature of the heating roller also influences the passage speed. Higher temperatures allow higher throughput speeds.
  • the heating roller emits a constant temperature to the film.
  • the heating roller has a temperature of 120 to 240 0 C.
  • the decoration can be advantageously removed from the film, even at high throughput speeds.
  • the heat roller should give as possible a constant temperature and the film. Since oil can only very slowly change its temperature, in a preferred embodiment of the invention hot oil is used to heat the heating roller.
  • the mobility of the adjustment roller is not limited to two directions. It is also conceivable to allow a mobility of the adjusting roller in four directions in one plane. It is important that the movable adjustment roller can be adjusted so that the size of the contact surface of the film with the heat roller is changeable. Thus, depending on the temperature of the heating roller and the position of the adjusting roller, it is possible to optimally adjust the device so as to allow a high speed of passage of the film through the device. This provides economic benefits to the operator of the device.
  • the means for detaching the decoration from the film preheated by the heating roller to the object preferably utilize the so-called "release” technique
  • the "release” technique has the advantage that no adhesive is required for applying the decoration to the object.
  • a device of the type described in the introduction which comprises a heating roller for preheating the film, a profiled preforming roller arranged next to the heating roller for preforming the film, and means for releasing the decoration from the film preformed by the profiled preforming roller to the object.
  • the profiled preforming roller is formed on the surface with a negative profile of the surface of the object.
  • the preforming roller is arranged in the direction of the film passing through the devices after the heating roller. With the help of the preforming roller, the film is prepared for the "release" process so that the film does not wrinkle or bubble even at high throughput speeds and does not shrink.
  • the preforming roller is designed to be movable in at least two directions. Thereby, it is possible for the preforming roll to flexibly communicate the film with the object, thus avoiding wrinkling of the film.
  • the preforming roller is made of silicone foam at least on its surface.
  • Silicone foam has the properties of high sealability, high heat insulating capability, and almost unchanged property over a wide temperature range.
  • silicone foam is preferably suitable for bringing the heated film into contact with the object and preparing for the "release" process.
  • an advantageous embodiment of the invention provides that they have a profiled detaching roller for detaching the decoration from the film onto the object and means for heating the detaching roller.
  • the decoration is detached from the film by means of "release” technique and applied to the object, whereas for the "release” technique, it is necessary for the detaching roller to be heated.
  • the temperature can be variably adjusted in the means for heating the detaching roller. In particular, a rapid change in temperature should be possible if a change of the film is made with the same objects to be printed.
  • the means for heating the detaching roller on at least one infrared radiator has the advantage over known heating methods, for example heating with the aid of circulating air, that less energy is required.
  • the at least one infrared radiator produces a temperature of 80 0 C to 240 0 C.
  • the release roller is irradiated at a temperature of 80 0 C to 240 0 C.
  • the means for heating the peel roll over a surface of the surface of the peel roll are arranged, which is defined by a circular arc of the peel roll with a center angle of at least 160 ° and the width of the peel roll.
  • the means for heating the detaching roller are formed by infrared radiators, this would mean that a plurality of infrared radiators are arranged above the surface of the detaching roller. It is also conceivable to use a single circular infrared radiator.
  • the detaching roller consists of silicone at least on the surface.
  • Silicone has the property that it is heat resistant and yet has a high rigidity, in particular a higher stiffness than, for example, silicone foam.
  • silicone is preferably adapted to absorb the heat from the means for heating the release roller and to release by pressure the decoration of the film with the aid of "release" technique and applied to the object.
  • the device has a drive roller.
  • the rotational speed of the drive roller is adjustable so that the speed of passage of the film through the device can be controlled.
  • the device according to the invention on a motor-driven drive roller whose rotational speed dictates the passage speed of the film through the device.
  • the passage speed of the film through the device can be adjusted.
  • the object is also achieved by a method of the type described above with the steps of preheating the film by means of a heating roller, adjusting the size of the contact surface of the film with the heating roller by means of a movable in at least two directions setting roller, which is arranged adjacent to the heating roller, and Detaching the decoration from the film preheated by the heating roller to the object, and a method of the type described above comprising the steps of preheating the film by means of a heating roller, preforming the film by means of a profiled deformation roller arranged adjacent to the heating roller and detaching the decoration from that of Heat roller preheated film on the object, solved.

  • a film 1 with "release” properties passes through a device for applying decoration on a film to an object 2.
  • the film is a so-called “sand wiper structure made of two polypropylene layers and an intermediate layer of polypropylene foam
  • the "SandwicrT” structure is preferably produced by means of a coextrusion process
  • the film has a thickness of 50 ⁇ m
  • the structure of the film of polypropylene and polypropylene foam has the Advantage that the film does not wrinkle even at high throughput speeds through the device, and yet is flexible.
  • polypropylene is preferred because polypropylene has a poor adhesive property, and thus decor or paint layer can be easily peeled off the film, but due to the poor adhesive property, it is difficult to decorate the film
  • the outer polypropylene layer of the film for applying the decoration to the film is subjected to corona treatment, which is adhered to the film by the corona treatment, but can be released again from the film by "release” technique and thereby open the object will be applied.
  • the corona treatment is carried out with a surface tension energy on the surface of the film of 35 to 45 dyne.

If the adjustment roller 6 is moved in the direction 6A, for example, the contact surface b of the film 1 increases with the heat roller 7. However, if the adjustment roller 6 moves in the direction 6B, the size of the contact surface b of the film 1 decreases with the heat roller 7.
  • the angle ⁇ decreases or increases, which leads to a change in the center angle ⁇ or the contact surface b. It is also conceivable that the adjusting roller 6 is formed such that it is movable in other directions in the image plane. Importantly, however, the adjustment roller 6 is a means for adjusting the contact surface b of the film 1 with the heat roller 6.
  • the heating roller 7 is fixedly arranged in the embodiment according to FIG. It is made of metal and has a hollow interior (not shown).
  • the heating roller 7 is heated by means of an oil heater (not shown), wherein the heating roller emits a temperature of 120 ° to 240 °, preferably 180 0 C, to the film. It is preferred to use oil for heating the heating roller 7, since oil changes its temperature only very slowly
