Embodiment Construction

[0036] First, combined with Figure 8~ Figure 10 The structure of an offset printing machine will be described. In this embodiment, the type of printing unit is an offset printing machine that supplies water and ink separately.

[0037] In Figure 9 and Figure 10 Among them, the sheet separating and supplying device 1 separates sheets (such as business cards, cards, and envelopes, plastics, etc.) S stacked in the storage section one by one from the uppermost side, and supplies them. The sheet conveying device 2 feeds the separated sheet S to the printing unit 3 at a predetermined time. The sheet conveying device is provided with conveying claws (not shown) that abut against the rear end of the sheet S and feed the sheet into the printing section, and several pressure rollers 4 arranged in series along the conveying direction of the sheet S . The printing unit 3 can perform monochrome printing on the sheet S, and of course can also perform color printing. Using an image sc...

Abstract

The present invention provides a sheet separating and supplying device capable of simplifying a sheet separating and supplying mechanism, reducing the cost of the device, and being easy to maintain. According to the sheet separating and supplying device of the present invention, the moving mechanism of the suction part and the air suction mechanism are driven and transmitted from the side of the device body (6) through the same drive transmission mechanism, and can be connected with the reciprocating movement of the suction part (30) to perform air suction. The opening and closing of the suction valve (45).

Description

technical field [0001] The present invention relates to a sheet separating and supplying device for separating and supplying paper sheets such as business cards, postcards, envelopes, and single sheets from the supplying device one by one, and an offset printing machine provided with the sheet separating and supplying device. Background technique [0002] A printing machine such as an offset printing machine is equipped with a supply device for stacking sheets such as business cards, postcards, envelopes, and single sheets of paper. The supply device separates the sheets one by one, and the supplied sheets are fed to the printing section for printing. There are various methods of separating and feeding sheets in this feeding device. [0003] For example, a paper feeding device has been proposed that absorbs and separates sheets stacked on a storage unit such as a loading table (JP-A-7-2382, JP-A-2001-179938, etc.). According to the paper feeding device disclosed in JP-A-7-2...
