Description

Automatic stamping machine.

The object of the present invention, as it is expressed in the statement of this specification, consists of a novel automatic stamping machine used to apply printed from transfer paper to textile or similar garments, by using heat.

A conventional drive stamper manual for this type of stamping works basically as a industrial plate: on a lower horizontal platform the operator places the garment to be printed, the paper is placed on it transfer with attached prints and, finally, on this set the operator manually lower a heating platform superior that applies heat and pressure simultaneously, so that Patterns are transferred from the transfer paper to the garment.

This conventional way of working presents Several inconveniences.

First, the pressure applied depends basically of the force exerted by the operator, which in turn goes by virtue of his own physical strength and his knowledge and experience in printing issues and, of course, of the type of garment and type of print to apply.

Second, the temperature at which it works the upper platform is usually unchanged and, therefore, the amount of heat applied to the transfer paper (so that the stamping is transferred to the garment) depends on the time that the operator keep the upper platform pressure against the lower.

Third, the fact that the temperature at the one that works the upper platform is constant, implies that the heating device thereof (normally resistance electric) is permanently activated; this means consumption extra energy unnecessary, because for as long as the operator leaves the upper platform in the raised position and dedicates to remove from the machine an already stamped garment (and its corresponding used transfer paper) to replace it with a new one garment to be printed (and its corresponding new transfer paper), the heating device continues to function unnecessarily.

To avoid these and other inconveniences, it has been designed the new automatic printing machine for textile garments, object of this technical report.

The new automatic press presents, with compared to traditional printers, the advantages that described below.

First, the stamping pressure applied the transfer paper and the garment will be constant throughout the entire application, since the new automatic press is equipped with pneumatic cylinder, which will be responsible for applying said pressure; In addition, the new press is equipped with a regulatory system of said pressure and can be adjusted to each type of garment and transfer paper

Second, the new automatic press It has a temperature regulating device that allows adjustment the maximum working temperature depending on the type of stamping to be carried out, of the type of textile garment and of the type of Transfer paper to be used.

Third, the novel stamping machine automatic incorporates an electrical switch device such that The power circuit of the heating electric heater it is activated automatically only during the stamping phase proper, being automatically disconnected said circuit during the replacement time, that is, the withdrawal of the printed garment and the used transfer paper and placement of the new garment and new transfer paper. In this way, saving energy during this replacement time can become important.

Fourth, the novel stamping machine automatic incorporates a new type of heating platform upper horizontal; This consists of a metal plate, preferably of aluminum, whose upper part has been integrated partially the heating electric resistance itself; of this mode, the heat transfer from the resistance to the metal plate is much more efficient and therefore much more fast In addition, this upper heating platform is equipped with exclusively vertical movement, thanks to the action of pneumatic cylinder described above that is placed in vertical position and thanks also to the presence of two guides verticals that perfectly direct said movement; when moving this platform in a perfectly vertical way, the pressure applied on the entire stamping surface is strictly equal for any point on said surface; with it achieves a quality of stamping much higher than that achieved with traditional methods.

Finally, the new press has optionally of an adjustable timer to notify (visual and / or acoustically) to the operator that the time has elapsed Preset for a certain stamping phase.

Also optionally, the new printing machine it can be equipped with a programmable automaton (P.L.C.) or similar and its corresponding equipment (sensors, solenoid valves, etc.), which would allow programming for different types of prints quickly and easily.

The new stamping machine consists of a chassis that supports all components, at the bottom of which a removable loading tray is located on which will deposit the garment to be stamped. This tray moves horizontally along guides provided on the sides of the chassis can be completely removed from the body of the machine  to be able to load the garment comfortably.

On the loading tray, and when it is inserted in the chassis, the heating platform that Fold vertically using two cylindrical guides incorporated in the same that move through a support bridge fixed to the chassis.

This displacement is facilitated through pneumatic cylinder whose body is fixed to the support bridge from the chassis while head to the heating platform.

The activation of the heating platform is performed with the mediation of an automatic switch formed by two contacts arranged one at the end of one of the guides cylindrical of the heating platform and another in a support associated to the chassis bridge, so that when the guide both contacts descend touching the circuit of integrated resistance supply.

Finally, the machine incorporates a box of control with a start-up switch, a screen for the temperature display of the heating platform, a regulator of said temperature, a timer and a command pressure regulator acting on a regulating valve pneumatic pressure

The operation of the new printer is You can consider divided into two phases: the configuration phase and the production phase itself.

In the configuration phase, the operator must adjust the appropriate parameters for the type of stamping that going to perform: temperature adjustment of the heating platform upper using the thermostat, setting the stamping time using the timer and setting the stamping pressure by the pneumatic pressure regulating valve.

In the production phase, the operator extracts the bottom tray along its longitudinal guides, place on it the garment to be printed, place the paper on the garment transfer, reintroduce the lower platform into the chassis and actuates the activation button of the pneumatic cylinder located in the control panel, bringing the upper platform down on the bottom to join her and leave the garment compressed along with the transfer paper; after the time of stamping selected by the timer, the cylinder tire retracts so the heating platform rises and it separates from the lower one; then the operator extracts from again the lower tray which will slide back along from its longitudinal guides and finally pulls the garment freshly stamped together with the transfer paper already used.
