Description: BACKGROUND OF THE INVENTION The present invention relates to an apparatus for automatically and simultaneously ironing shirt front, rear and top portions, which has been specifically designed to be used in the cloth article making industry. As is known any cloth article must be suitably ironed in order to remove therefrom the cloth folds. On the other hand, at present for ironing shirts there are only available apparatus provided for ironing the front and rear portions of the shirts. Then, by using such an apparatus, it is necessary to carry out other shirt processing steps, for ironing, for example, the sleeves, the shoulders and neck of the shirts. These further processing steps, as it should be apparent require a lot of expensive labour which negatively affects the cost of the finished cloth article. Moreover, in conventional shirt ironing apparatus, the partially ironed shirts are manually taken from their supporting dummy, in order to be subjected to a further shirt body ironing step, which further increases the cost of the finished product. The document US-A-3 036 606 discloses an ironing apparatus having substantially the features of the preamble of the main claim. The document DE-A-1 926 667 describes a short unloader near a shirt pressing machine having a conveyor arm with grippers which lift the shirt from the pressing device and transport it to a delivery station in one overhead swinging movement. SUMMARY OF THE INVENTION Accordingly, the aim of the present invention is to overcome the abovementioned drawbacks, by providing a shirt ironing apparatus, for industrial use, which is specifically designed to reduce the shirt ironing time to a minimum. Within the scope of the above aim, a main object of the present invention is to provide a shirt ironing apparatus, for industrial use, which is adapted to simultaneously iron the body and shoulder portions of the shirts. Another object of the present invention is to provide such a shirt ironing apparatus for industrial use, which also comprises a device for automatically take up an ironed shirt from its supporting dummy. According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by an apparatus for automatically and simultaneously ironing shirt front, rear and top portions, having the features of the characterizing part of the main claim.

DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the figures of the accompanying drawings, the apparatus for automatically ironing shirts according to the present invention essentially comprises two vertical parallel ironing plates 1 and 1' which can be driven toward one another by suitable driving elements. More specifically, these two plates have top portions thereof, indicated respectively at 2 and 2', which have a concave profile adapted to mate with the profile of the corresponding top portions of the dummy 3 supporting a shirt 4 to be ironed. In this connection it should be pointed out the mentioned dummy is supported by a shaped plate 5 and that its top portion 3' is adapted to be upward driven by a rod 6 which is resilienty biassed, said rod being operated by a pressing cylinder 7. It should be moreover pointed out that the dummy is hollow and communicates with a sucking duct 8 provided for always holding the dummy under a negative pressure so as to cause the shirt to suitably adhere to he outer surface of the dummy. The dummy is moreover provided, at the top thereof, with a restraining element 9, for restraining the neck portion 4' of the shirt and with an opposite cylinder pair 10 and 10'. These cylinders are provided for reciprocating corresponding rods 11 and 11' which can be introduced into the sleeves 4'' of the shirt so as to hold these sleeves separated from the shirt body during the shirt ironing operation. In one of the mentioned ironing plates, in particular, there is formed, at the dummy portion bearing the restraining element, an interruption 12 of half-round profile. The dummy supporting plate 5 bears, at the bottom thereof, a pair of fork elements 13, provided with corresponding roller pairs 14 which can slide along the two sides of a first horizontal track 15. The supporting plate, moreover, downward extends, by a doubly-bent portion 16 which supports two grooved rollers 17, which can slide on a second horizontal track or rail 18 provided for supporting the assembly. The transfer of the dummy bearing thereon a shirt to be ironed, arranged between the two ironing plates, is performed by a double-acting cylinder 19 the rod of which is articulated to the above mentioned supporting plate. Advantageously, the apparatus according to the invention further comprises a rail double pair (as is clearly shown in figure 4) extending according to converging paths toward the ironing plates. Thus, owing to this provision, as one of the dummy bearing a shirt to be ironed is arranged between the two ironing plates, the other dummy can be easily fitted with another shirt to be ironed. In operation, as shown in figure 5, the dummy is displaced between the ironing plates which are driven toward one another so as to contact the shirt by a light pressure. Simultaneously, there are actuated the side inflatable elements of the dummy so as to suitably spread the side portions of the shirt to be ironed. Then (as is shown in figure 6), the plates 1 and 1' are forcedly closed so as to lock the dummy (with the exception of the top portion thereof) and the shirt. Then, (see figure 7), the top portion 3' of the dummy, operated by the rod 6, is upward pushed so as to spread and press the shirt shoulder portions on said plates. The ironing apparatus according to the present invention further comprises a device for removing from the dummy the ironed shirt, after having suitable moved away from one another the two plates and having opened the shirt neck restraining element 9. In particular, this shirt removing or gripping device comprises a pair of pliers or grippers 20 mounted at the end portions of a tubular element 21 which is rotatably coupled to a supporting element 22 and bears rigid therewith a gear wheel 23. This supporting element is firmly restrained to an arm 24, supported on a shaft 25, which is adapted to rotatively reciprocate into the two directions, by means of a driving reducing unit 26. Coaxially with respect to the mentioned shaft there is provided a fixed supporting element 27 therewith there is rigid a further gear wheel 28 which, together with the first mentioned gear wheel, supports a chain 29. Thus, as the above mentioned arm is turned either in one or in the other direction, in order to grip and remove the ironed shirt, by means of the pliers 20, it will cause the tubular element 21 to correspondingly turn so as to always hold the pliers in a vertical arrangement (see figure 9). From the above disclosure and the figures of the accompanying drawings it should be apparent that the invention fully achieves the intended aim and objects. While the invention has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that the disclosed embodiment is susceptible to several modifications and variations, all of which will come within the scope of the appended claims.
