Description

(1) The invention will be explained further hereinafter by way of the accompanying schematic drawing, wherein shows:

(2) FIG. 1 a schematic illustration of the device according to the invention for printing textile surfaces;

(3) FIG. 2 a schematic illustration of the device according to the invention for printing textile surfaces pursuant to FIG. 1, with one printing means being in each case arranged on both sides of the longitudinal beam;

(4) FIG. 3 a schematic illustration of the device according to the invention for printing textile surfaces pursuant to FIG. 1, with an additional printing means being arranged on a second side of the longitudinal beam.

(5) FIG. 1 shows an embodiment of the device 10 according to the invention, in which two guide rails 40, 42 are arranged in parallel next to each other and transversely to a longitudinal axis along the longitudinal beam 50. These can form the tracks 41, 43, along which the respective pallets 21 and 31 as well as 24 and 34 can be arranged in a movable manner. According to the invention, provision can also be made for more than two tracks, in particular three, four, five or more, in particular having guide rails and pallets. Hence, the set-up station 20 according to FIG. 1 has two pallets 21, 24, with one of the two pallets being in each case arranged on one of the guide rails 40, 42. The pallets 21 and 24 can be moved independently of each other on their respective guide rails 40 and 42 between their set-up positions 22, 25 in the set-up station 20 and the printing position. Likewise, in the second set-up station 30 two further pallets 31, 34 are also provided according to the embodiment of FIG. 1, in which case the further pallet 31 has a printed textile that is moved between the printing position and the second set-up station 30 and the further pallet 34 is delivered to the printing means 52. According to FIG. 1 the pallet 21 is in the process of being delivered to the printing position. This can take place already at the stage when the pallet 31 has not yet reached the second set-up station 30. The same applies to pallets 24 and 34.

(6) The pallets of the set-up station 20 or the second set-up station 30 can in particular be delivered simultaneously to their respective printing positions in the area of the longitudinal beam 50.

(7) Along the longitudinal beam 50 one printing means 51, 52 is in each case provided for a pair of pallets that are supported on a joint rail 40, 41 (FIG. 1). The printing means 51, 52 are designed to move independently of each other in a longitudinal direction along the longitudinal beam 50. This also enables a delivery of both printing means 51, 52 to the printing position of a single pallet. Especially in the case of a simultaneous delivery of several pallets of one of the set-up stations 20, 30 the printing means 51, 52 can jointly print the several pallets. In this way, the two printing means can also print e.g. three, four, five or more pallets of the same set-up station 20, 30. As a result, an efficient utilization of the printing means 51, 52 is rendered possible.

(8) An expedient embodiment can reside in the fact that pallet pairs of several parallel guide rails can be printed by means of a single printing means. In the manner set out above, any desired number of pallet pairs, which are in each case supported on a joint guide rail, can be provided in parallel next to each other. Concerned here can be an arrangement which basically corresponds to a multiple of the embodiment according to FIG. 1. Alternatively, such a device can be designed with only a single printing means, by means of which textiles can be printed on all pallets delivered to the printing position.

(9) According to FIG. 1 the printing means 51, 52 are arranged on the same side of the longitudinal beam 50.

(10) FIG. 2 shows an embodiment of the present invention, in which the printing means 51 and 52 are arranged on opposite sides of the longitudinal beam 50. Each of the printing means 51, 52 can be moved independently of the respective other printing means 51, 52 in a longitudinal direction along the longitudinal beam 50. Thus, each of the printing means is designed to assume the respective printing position on each of the tracks 41, 43 independently of the position of the further printing means and to print a textile on the respective pallet that has been delivered to the printing position of the corresponding track. Likewise, according to the embodiment pursuant to FIG. 2 several pallets 21, 24 or 31, 34 of the same set-up station 20 or 30 can be delivered simultaneously to their respective positions in the area of the longitudinal beam 50, in which case the printing means 51 and 52 are designed to jointly print the textiles on the pallets. Likewise, according to the embodiment pursuant to FIG. 2 three, four, five or more tracks with two pallets each can be arranged next to each other which, just as in FIG. 1, are arranged underneath a joint longitudinal beam 50. The two printing means 51, 52 can thus also jointly print three, four, five or more textiles on pallets delivered from the same or different set-up stations to the printing position in the area of the longitudinal beam 50.

(11) In FIG. 3 a further embodiment of the printing device 10 according to the invention is illustrated. This differs in particular from the embodiment according to FIG. 1 in that a further printing means 53 is arranged on a second longitudinal side of the longitudinal beam 50. This is arranged such that it can be moved in an unrestricted manner along the longitudinal beam 50 across the width of the printing device 10. Just as in the embodiments according to FIG. 1 and FIG. 2, the printing means 51, 52 and 53 are designed to print one or several pallets of the same or of different tracks, in which case, also according to the embodiment pursuant to FIG. 3, several tracks, i.e. 3, 4, 5 or more tracks can be arranged in parallel to each other underneath the longitudinal beam 50.
