Module for sheet-fed perfecting multi-color printing press, printing unit and sheet-fed perfecting multi-color printing press, and manufacturing methods therefor
An apparatus and a method in which when both of two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses are manufactured, there is no need for a manufacture of extra parts or an extra stock, and also the replacement and servicing of parts are easy in the event of a failure of a printing unit or the sheet-fed perfecting multi-color printing press. For this purpose, modules for the printing unit for the sheet-fed perfecting multi-color printing press, each of which consists of a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism are manufactured, and the modules are used to manufacture the two-stage type and impression cylinder connecting type sheet-fed perfecting multi-color printing presses.
1. A method of making a printing unit for a sheet-fed perfecting multi-color printing press from independent replaceable modules, each module comprising a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism, the method comprising the steps, of:
assembling the printing unit from a plurality of the independent modules, the printing unit including two types of modules A and A′, each including an intermediate cylinder, an impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism, and a module B for a sheet-fed perfecting multi-color printing press including a blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism; and
assembling a top surface printing unit and a back surface printing unit by combining said modules A, A′ with module B, in which said modules A and A′, each having an intermediate cylinder, are used in said printing unit when a unit for a two-stage type sheet-fed perfecting multi-color printing press is assembled; and assembling a top surface printing unit and a back surface printing unit by combining said A, A′ with module B, in which the intermediate cylinder of module A′ is replaced with the impression cylinder so that the module A′ in which the intermediate cylinder is replaced with the impression cylinder and module B are used when a unit for an impression cylinder of module B connection type sheet-fed perfecting multi-color printing press is assembled.
2. A method of making a printing unit for a sheet-fed perfecting multi-color printing press from independent replaceable modules, each module comprising a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism, the method comprising the steps of:
assembling the printing unit from a plurality of the independent modules, the printing unit including two types of modules C and C′ for a sheet-fed perfecting multi-color printing press, each including an impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism; and
assembling a top surface printing unit and a back surface printing unit by combining said modules C and C′, in which an intermediate cylinder is intervened between the impression cylinders of said modules C and C′ when a unit for a two-stage type sheet-fed perfecting multi-color printing press is assembled; and assembling a top surface printing unit and a back surface printing unit by combining said modules C and C′, in which the impression cylinders of said modules C and C′ are directly disposed in parallel with each other when a unit for an impression cylinder connection type sheet-fed perfecting multi-color printing press is assembled.
3. A method of making a printing unit for a sheet-fed perfecting multi-color printing press from independent replaceable modules, each module comprising a combination of at least two elements of a group consisting of an intermediate cylinder, impression cylinder, blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism, the method comprising the steps of:
assembling the printing unit from a plurality of the independent modules, the printing unit including two types of modules D and D′ for a sheet-fed perfecting multi-color printing press, each including an intermediate cylinder and an impression cylinder, and two types of modules E and E′ for a sheet-fed perfecting multi-color printing press each including a blanket cylinder, plate cylinder, inking mechanism, and water supply mechanism;
assembling a unit for a two-stage type sheet-fed perfecting multi-color printing press by combining said modules D, D′ with modules E, E′; or
assembling a unit for an impression cylinder connection type sheet-fed perfecting multi-color printing press by combining said modules E, E′ with only impression cylinders.
