Abstract

This invention discloses a numbering and imprinting machine including a number cylinder, moving inker, first cleaning device, second cleaning device, inker position detector, and control device. The number cylinder includes at least one numbering device. The moving inker includes a number inker which supplies ink onto the number cylinder, and is movable between a printing position at which the number inker comes into contact with the number cylinder, and a retraction position at which the number inker separates from the number cylinder. The first cleaning device cleans the number cylinder. The second cleaning device cleans the number inker. The inker position detector detects the position of the moving inker. When the inker position detector detects that the moving inker is set at the printing position, the control device rotates the number cylinder, drives the number inker and controls cleaning operations by the first cleaning device and the second cleaning device.

First claim

What is claimed is:

1. A numbering and imprinting machine comprising:
a number cylinder which is rotatably supported by main body frames, and includes at least one numbering device mounted on an outer circumferential surface thereof;
a moving inker which includes a number inker that supplies ink onto said number cylinder, and an inker frame on which said number inker is mounted, said moving inker being movable between a printing position at which said number inker comes into contact with said number cylinder, and a retraction position at which said number inker separates from said number cylinder to form a maintenance space between said inker frame and said number cylinder, said maintenance space allowing an operator to enter and to perform a maintenance operation therein;
a first cleaning device which is mounted on the main body frames, and cleans said number cylinder;
a second cleaning device which is mounted on said moving inker and cleans said number inker;
an inker position detector which detects a position of said moving inker; and
a control device which, when said inker position detector detects that said moving inker is set at the printing position, rotates said number cylinder, drives said number inker and controls cleaning operations by said first cleaning device and said second cleaning device, and, when said inker position detector detects that said moving inker is set at the retraction position, inhibits said number cylinder from rotating at a printing speed and rotates said number cylinder only according to the operations performed by the operator who has entered the maintenance space.

2. A machine according to claim 1 , wherein
said first cleaning device includes
a brush member which is movably supported by the main body frames, and moves in contact with said numbering device to clean said numbering device, and
a brush member drive device which moves said brush member while said brush member is in contact with said numbering device, and
said control device controls said brush member drive device to move said brush member when said moving inker is set at the printing position.

3. A machine according to claim 2 , further comprising:
a drive motor which rotates said number cylinder; and
a phase detection device which detects a rotary phase of said number cylinder,
wherein said numbering device includes a plurality of numbering devices arranged to form a plurality of numbering device lines on each of which said plurality of numbering devices align themselves in an axial direction of said number cylinder, said numbering device lines being arranged at a predetermined interval in a circumferential direction of said number cylinder, and
said control device controls said drive motor, based on the detection result obtained by said phase detection device, so as to stop said number cylinder while said brush member is in contact with one of said plurality of numbering device lines on each of which said plurality of numbering devices align themselves in the axial direction, and controls said brush member drive device to move said brush member in contact with said plurality of numbering devices which form the one of said plurality of numbering device lines.

4. A machine according to claim 3 , wherein after the one of said plurality of numbering device lines is cleaned, said control device drives said drive motor, based on the detection result obtained by said phase detection device, so that said brush member comes into contact with the next numbering device line adjacent to the cleaned numbering device line in the circumferential direction of said number cylinder.

5. A machine according to claim 2 , wherein
said brush member is supported to be simultaneously movable in a plurality of directions substantially parallel to contact surfaces with said plurality of numbering devices, and
said brush member drive device moves said brush member in the plurality of directions substantially parallel to the contact surfaces of said plurality of numbering devices.

6. A machine according to claim 5 , wherein
said brush member includes a brush roller supported to be rotatable and swingable in the axial direction, and
said brush member drive device includes a brush rotary drive device which rotates said brush roller, and a brush swing drive device which swings said brush roller in the axial direction.

7. A machine according to claim 1 , wherein
said number inker includes a ink fountain roller that sullies ink onto said number cylinder,
said second cleaning device includes
a doctor which removes ink on a circumferential surface of the ink fountain roller as a distal end thereof comes into contact with the circumferential surface of the ink fountain roller,
a doctor attaching device which moves said doctor between an attachment position at which the distal end of said doctor comes into contact with the circumferential surface of the ink fountain roller, and a detachment position at which the distal end of said doctor separates from the ink fountain roller, and
a cleaning liquid supply device which supplies a cleaning liquid onto the circumferential surface of the ink fountain roller, and
said control device controls said cleaning liquid supply device to supply the cleaning liquid onto the circumferential surface of the ink fountain roller, and controls said doctor attaching device to set said doctor at the attachment position, when said moving inker is set at the printing position.

8. A numbering and imprinting machine comprising:
a number cylinder including a plurality of numbering devices arranged to form a plurality of numbering device lines on each of which said plurality of numbering devices align themselves in an axial direction of said number cylinder, said numbering device lines being arranged circumferentially;
a drive motor which rotates said number cylinder;
a brush member which is supported movably and moves in contact with said numbering cylinder to clean said plurality of numbering devices;
a brush member drive device which moves said brush member in a plurality of directions substantially parallel to contact surfaces with said plurality of numbering devices;
a phase detection device which detects a rotary phase of said number cylinder; and
a control device which controls said drive motor, based on the detection result obtained by said phase detection device, so as to stop said number cylinder while said brush member is in contact with one of said plurality of numbering devices which form one of said plurality of numbering device lines, and controls said brush member drive device to move said brush member in contact with the one of said plurality of numbering device lines.
