Embodiment Construction

[0033] The description of the device and the drawings should be understood as also a disclosure of the method.

[0034] Figure 1 shows an embodiment with an ink fountain 10 which may be of a standard type and supplies ink to printing presses which are also of standard type, but those of the printing presses not shown in the figure are of ordinary skill in the art. Easy-to-understand parts for technicians. A conduit 11 is adapted to be mounted directly above the ink fountain 10 and has a nozzle 12 pointing downwards and directing the flow of ink from the conduit 11 into the ink fountain 10 . In some constructions, the actual nozzle 12 may be omitted and a simply shaped or tapered outlet may be provided in the conduit 11, as shown in other figures.

[0035] A rigid container 13 has a lower opening 14 and supports a quantity of ink contained in a pouch 16, although the container 13 has only one size, the pouch 16 can be of various sizes. A feed tube 17 is suitably connected to ...

Abstract

A method and apparatus for dispensing ink to an ink fountain (10) of a printing press. A flexible bag (16) of ink is utilized and is compressed for forcing the ink into the fountain (10), and a sensor (94) determines the level of ink in the fountain and thus controls the force on the bag, that is, the compression on the bag. The flexible bag (16) of ink is subjected to a compressor, which can be a flexible air-filled bladder (22) which applies a force against the ink bag (16) to compress the bag, and to force ink therefrom and into the ink fountain (10).

Description

technical field [0001] The present invention relates to methods and apparatus for dispensing ink to printing presses. More specifically, the present invention relates to a method and apparatus for dispensing ink to a printing press, wherein the ink is completely confined at its dispensing location and within the ink fountain of the printing press, while the apparatus is easily cleaned, Moreover, inks of various colors can be dispensed by intermittent cleaning. Background technique [0002] In current conventional methods of dispensing ink for printing presses, ink is typically drawn from a rigid container and dispensed into an ink fountain, which can be done manually. In some prior art arrangements, ink is supplied manually to the press fountain and the original ink container must be left to dry and become unusable. This and other methods are the state of the art and are considered time-consuming, unclean and wasteful of ink, while also requiring constant monitoring by the...
