Definitions

• the invention relates to a tampon printing machine for printing products by means of a tampon according to the preamble of claim 1.
• a pad printing machine of this type is known from US 5,662,041. It is called the pad printing machine and the tampon is called the transfer pad.
• the tampon or transfer pad is a stamp element made of resilient material.
• a pad printing machine can be designed for fully automatic operation or for manual operation.
• the range of movement of the tampon carrier and the plate holder is preferably shielded for safety reasons, so that no hand can be trapped between them on the one hand and a product carrier on the other.
• Two-hand operating device is provided, by means of which the pad printing machine can only be switched on if two operating elements that are at a distance from each other are operated simultaneously with both ends.
• the object of the invention is to provide a tampon printing machine of the type mentioned in such a way that it can be used in a variety of ways without requiring expensive design measures.
• the invention relates to a pad printing machine, comprising a plate holder, which together with a plate carried by it can be moved back and forth in a first x-line between an ink receiving position and an ink dispensing position relative to an ink cup in a first guide device, the ink cup on the Surface of the plate slides and is open to the surface of the plate, and wherein at least one printed image recess is formed in the surface of the plate, which is located in the ink-receiving position under the ink cup and is positioned in the ink-dispensing position beyond the first guide device; a tampon carrier, which can be moved along a first y-line transversely to the first x-line between an upper rest position and a lower cliché contacting position in a second guide device when the cliché carrier is in the ink delivery position, by means of a tampon carried by the tampon carrier, of printing ink to take from the print image deepening of the cliché; the tampon carrier, after

• Products can be printed in the second y-line which are significantly wider than products in the first y-line because the second y-line is further away from the plate holder than the first y-line. It is also possible to print a product that extends across both y-lines simultaneously in both y-lines.
• Another possibility of the invention is to position a cleaning device for cleaning the tampon in the second y-line in order to avoid that a product position on the product carrier in the first y-line fails due to a cleaning device for cleaning to be arranged there of the tampon.

• the product 28 is carried by a product carrier 30 and held in a predetermined position.
• the printing position 20-3 can be at any height below the rest position 20-1, but is preferably below the plate contacting position 20-2 so that the tampon 20 can print on the product 28 without the product carrier 30 being moved up and down got to.
• the product carrier 30 can be designed in various ways, for example for holding only a single product 28 or for holding a plurality of products 28, the product carrier 30 being movable in a straight line in a horizontal plane or being rotatable about an axis of rotation can and the products 28 are arranged one after the other in a row in the direction of movement of the product carrier 30, so that one product 28 can be positioned one after the other in the first y-line 24 and under the tampon for printing.

If the tampon carrier 22 with the tampon 20 is in the second y-line 36, the tampon 20 can be exchanged more easily than in the first y-line 24 because of the greater distance from the front edge 24 of the first guide device 10 and the machine base 26 more space is available. Furthermore, a cleaning device for cleaning the tampon 20 can be provided in the second y line 36, the cleaning of the tampon at the first level 20-1 or the second level 20-4 depending on the embodiment and positioning of the cleaning device. The cleaning of the tampon in the second y line 36 has the advantages that more space is available than in the first y line 24 and that there is no space on the product carrier 30 for printing on products in the first y line 24 28 is lost for a cleaning station.
