Abstract

In order to provide a numbering and imprinting machine capable of minimizing the amount of wasted paper produced, the numbering and imprinting machine is provided with: a first-number inspection camera (124B) that is arranged downstream of the position of contact between an impression cylinder (112) and a first-number cylinder (113) of a first-number printing unit (111) in the direction of rotation of the impression cylinder (112), and images a first number printed on paper (W) held on the impression cylinder (112); a second number inspection camera (124C) that is arranged downstream of the position of contact between an impression cylinder (117) and a second-number cylinder (118) of a second-number printing unit (116) in the direction of rotation of the impression cylinder (117), and images a second number printed on paper (W) held on the impression cylinder (117); and a printing-press control device (10) that controls first- and second-number-cylinder throw-on and throw-off devices (38, 39) based on signals from the first- and second-number inspection cameras (124B, 124C) to cause the first-number cylinder (113) and the second-number cylinder (118) to make separating movements.

First claim

The invention claimed is:

1. A numbering and imprinting machine comprising:
a first-number printing device including
a first-number impression cylinder that holds and transports a sheet,
a first-number cylinder that is arranged to be movable to come into contact with and separate from the first-number impression cylinder and performs first-number printing on a sheet held on the first-number impression cylinder, and
a first ink feeding device for feeding ink to the first-number cylinder;

a second-number printing device including
a second-number impression cylinder that is arranged downstream of the first-number printing device in a sheet transport direction and holds and transports a sheet from the first-number printing device,
a second-number cylinder that is arranged to be movable to come into contact with and separate from the second-number impression cylinder and performs second-number printing on a sheet held on the second-number impression cylinder, and
a second ink feeding device for feeding ink to the second-number cylinder;

a first-number-cylinder contacting-separating-movement device for causing the first-number cylinder to move to come into contact with and separate from the first-number impression cylinder;
a second-number-cylinder contacting-separating-movement device for causing the second-number cylinder to move to come into contact with and separate from the second-number impression cylinder;
a first-number imaging device that is arranged downstream of a position of contact between the first-number impression cylinder and the first-number cylinder in a direction of rotation of the first-number impression cylinder, for imaging a first number printed on a sheet held on the first-number impression cylinder;
a second-number imaging device that is arranged downstream of a position of contact between the second-number impression cylinder and the second-number cylinder in a direction of rotation of the second-number impression cylinder, for imaging a second number printed on a sheet held on the second-number impression cylinder;
a number inspecting device for determining whether or not the first number and the second number printed on a sheet are satisfactory based on image signals from the first-number imaging device and the second-number imaging device; and
a controlling device for controlling the first-number-cylinder contacting-separating-movement device and the second-number-cylinder contacting-separating-movement device based on a dissatisfactory signal from the number inspecting device to cause the first-number cylinder and the second-number cylinder to make separating movements.

2. The numbering and imprinting machine according to claim 1 , further comprising:
a seal printing device including
a seal impression cylinder that is arranged upstream of the first-number printing device in the sheet transport direction, holds a sheet, and transports the sheet toward the first-number printing device,
a seal cylinder that is arranged to be movable to come into contact with and separate from the seal impression cylinder and performs seal printing on a sheet held on the seal impression cylinder, and

a third ink feeding device for feeding ink to the seal cylinder;
a seal-cylinder contacting-separating-movement device for causing the seal cylinder to move to come into contact with and separate from the seal impression cylinder;
a seal imaging device that is arranged downstream of a position of contact between the seal impression cylinder and the seal cylinder in a direction of rotation of the seal impression cylinder, for imaging a seal printed on a sheet held on the seal impression cylinder; and
a seal inspecting device for determining whether or not the seal printed on a sheet is satisfactory based on an image signal from the seal imaging device, wherein
the controlling device controls the seal-cylinder contacting-separating-movement device, the first-number-cylinder contacting-separating-movement device, and the second-number-cylinder contacting-separating-movement device based on a dissatisfactory signal from the seal inspecting device or the number inspecting device to cause the seal cylinder, the first-number cylinder, and the second-number cylinder to make separating movements.

3. The numbering and imprinting machine according to claim 1 , wherein the controlling device outputs an emergency separating movement signal for causing the first number cylinder and the second-number cylinder to make an emergency separating movement to the first-number-cylinder contacting-separating-movement device and the second-number-cylinder contacting-separating-movement device based on the dissatisfactory signal from the number inspecting device.

4. The numbering and imprinting machine according to claim 3 , wherein the controlling device controls the first-number cylinder contacting-separating-movement device and the second-number-cylinder contacting-separating-movement device based on the emergency separating movement signal to cause the first-number cylinder and the second-number cylinder to make an emergency separating movement at an emergency cylinder movement timing different from a normal cylinder movement timing used when a printing operation is ended.

5. The numbering and imprinting machine according to claim 2 , further comprising:
an inkjet device provided at a delivery unit; and
a mark imaging device provided at a sheet feeder, wherein
the controlling device
controls the inkjet device based on the dissatisfactory signal from the seal inspecting device or the number inspecting device to print on a sheet a mark that varies depending on a printing condition,
controls the mark imaging device to image the mark printed on the sheet by the inkjet device, and
controls the seal-cylinder contacting-separating-movement device, the first-number-cylinder contacting-separating-movement device and the second-number-cylinder contacting-separating-movement device according to a mark identified based on an image signal from the mark imaging device.

6. The numbering and imprinting machine according to claim 2 , wherein the controlling device outputs an emergency separating movement signal for causing the seal cylinder, the first-number cylinder, and the second-number cylinder to make an emergency separating movement to the seal-cylinder contacting-separating-movement device, the first-number-cylinder contacting-separating movement device, and the second-number-cylinder contacting-separating-movement device based on the dissatisfactory signal from the seal inspecting device or the number inspecting device.
