Definitions

  • the present invention is directed to a heat transfer press, of the type used to print or transfer images by applying pressure and heat from a media to a fabric, or to another receiving surface.
  • a typical example of use can be found in images printing on T-shirts or other garments. Such printing could take place in a specialized workroom or even directly in a retail shop, in order to personalized the garment according to the client's instructions.
  • Another example of use is related to the printing of images, writings or number on T-shirt for playing sports, where single players are thus identified by the T-shirt they are wearing. Therefore, the printing could also be related to sponsorships, personalized writings and so on.
  • images will refer either to the ones transferred from a decalcomania media or the like, or even to images on a media thermally glued on the final surface. Moreover, it is intended that the application is not limited to the textile field but could also concern other type of surfaces.
  • presses normally used for the above mentioned objects it is normally programmed a timed cycle during which pressure is exerted at a temperature.
  • the media comprising the image and the receiving surface are placed on a lower plate onto which an upper plate operates, providing said preset pressure.
  • the press upper plate or both the plates could be heated, e.g. by means of thermistors, for assuring the processes the correct temperature.
  • the two plates are placed horizontally, and the upper plate is supported by a substantially horizontal arm, that could be movable, in particular rotatable, for moving away and nearer the upper plate relative to the lower one.
  • the lower plate could be movable.
  • the pressure is manually provided, by means of a leverage.
  • a pneumatic or oleodynamic system is commonly used to exert pressure.
  • the press requires a compressor or a pump for providing the required pressure, which are bulky devices, not easily manageable and expensive, also in terms of power consumption.
  • the technical problem underlying the present invention is to provide a heat transfer press allowing to overcome the above-mentioned drawbacks.
  • a press as mentioned above, characterized in that it comprises, at said arm, a motor rotatably articulated to an arm distal portion and provided with an operating stem reciprocating in a direction substantially concordant to the arm one, operating on a leverage connected to a proximal portion of said arm, for exerting a predetermined pressure on said upper plate.
  • the main advantage of the press according to the present invention consists in allowing to house even a small sized motor above the arm, with the possibility of multiplying the force exerted from the motor through the leverage, e.g. with a toggle arrangement.
  • a heat transfer press is overall shown with the reference number 1, and an upper arm thereof, comprising the press drive motor which will be shown in the following, is overall shown with the reference number 2 and it represents substantially the press 1 upper portion.
  • the arm 2 projects substantially horizontally from a upright 5.
  • the joint between arm 2 and upright 5 could be formed by a hinge, so as to allow the rotation of the arm 2 on a substantially horizontal plane.
  • Said upright 5 is supported by support base 6 which is in turn supported by a press 1 lower plate 7.
  • such lower plate 7 is horizontally movable according to a substantially drawing-like arrangement. Accordingly, the lower plate 7 could be pulled out for allowing to place a print media, and subsequently retracted in an operative position.
  • the arm 2 is fixed.
  • the support base 6 holds two sided lower plates 7' and 7", and the arm 2 can rotate for alternatively hanging over the former or the latter, allowing to place a print media on the lower plate unconstrained from the arm which is then rotated in an operative position.
  • the support base 6 holds a single lower plate 7, and the arm 2 can be rotated away therefrom, for allowing to place a print media on the lower plate 7, and then approached back, in an operative position.
  • the arm 2 can be manually rotated by means of apposite handles 8 on the casing 3. With this regard, limit stops will be provided (not shown) so that the arm 2 assumes a correct operative position.
  • the arm 2 comprises a distal or rear portion, i.e. next to the upright 5, and a proximal or end portion, in correspondence of which the press 1 comprises a vertically movable upper plate 9, apt to exert pressure on the lower plate 7 during the printing step.
  • the upper plate 9 is heated by means of appropriate thermistors (not shown) held in its thickness and electrically supplied.
  • the supporting stem 10 is operated to a vertical reciprocating motion according to a way that will be detailed in the following.
  • the press 1 comprises an actuating motor 12 which, in the present exemplificative embodiment, includes a driving rotating pinion gear portion (not shown) and an operating stem 13 projecting from a housing 14 containing the other parts.
  • the driving rotating portion is substantially formed by an electric motor, conventionally supplied, so as to be able to reverse the rotation.
  • the operating stem 13 could be of the rack type or could be formed by a worm gear, with a not shown appropriate thread engaged in the rack.
  • the actuating motor 12 is substantially articulated to the arm distal portion 2, in correspondence to a hinge 15, so as to be rotatable relative to the arm 2.
  • the operating stem 13 has a projecting end 16 comprising an articulating element 17.
  • the connection between the articulating element 17 and the projecting end 16 is realized by a not shown bearing, in the case of the stem 13 is formed by a rotating shaft.
  • the press comprises a leverage 18 connected to a said supporting stem 10.
  • the leverage 18 is formed by a toggle lever, comprising a first lever element 19, articulated to said supporting stem 10, and a second lever element 20, articulated on an arm 2 fixed element 21, placed on the vertical of the supporting stem and of the upper plate 9 center.
  • the articulating element is rotatably connected to the articulated joint between said lever elements 19, 20 so that the force transmitted by the operating stem 12 is multiplied by the leverage 18 on the upper plate 9.
  • the motor 12 could operate the upper plate 9, lifting it or lowering it, allowing the latter to exert a predetermined pressure on the lower plate 7 and on the print media.
  • the motor 12 and its housing 14 could rotate for following the motion of the articulating element 17 joining the motor 12 to the leverage 18.
  • This drive motor system is supported on the arm 2 upper face and thus it can be rotated together with it in the embodiments of figures 4B and 4C . It is intended that the so-realized press does not comprise further external driving elements, but only electrical connections to supply the motor 12 and the thermistors on the upper plate 9.
  • the latter is influenced by the print media thickness, but it could be accordingly controlled by adjusting the stroke of the operating stem 13.
