Abstract

PURPOSE:To efficiently print an image accurately and clearly at a desired position on the surface of a small solid article by causing the surface speed of the article to be printed mounted on a carrier to coincide with that of a print roll. CONSTITUTION:In a device wherein printing is performed by causing the print roll 11 of a small rotary press 1 to contact with the surface of an article 2 to be printed, articles 2 to be printed are installed, by means of article mounting mechanism 5, to mounting parts 4 provided, at an equal interval, on the circumference of a disk-like carrier 3, and the disk-like carrier 3 is caused to intermittently rotate and move by means of an intermittent movement mechanism. The rotation of the print roll 11 is caused to synchronize with the movement of the carrier 3 and the surface speed of the print roll 11 is caused to coincide with the moving speed of the print surface of the article 2 to be printed when they are brought to contact each other, and by this arrangement relative slippage between the artilce 2 and the print roll 11 is eliminated and a clear image can be printed accurately at a desired position at all times without being deviated.

回転運動を繰返す機構即ち間欠運動機構によって間欠的
に回転運動を行わせる。As shown in FIG. 1, in a printing device that performs printing by bringing the surface of a printing material 20 into contact with a printing roll or a transfer roll, in the case of the figure, an offset row/Lllll of a small rotary printing press 1, a disk-shaped conveyor is used. The printing material 2 is fitted to the printing material mounting portions 4 provided at equal intervals on the peripheral edge of the body 30 by the printing material mounting mechanism 5, and the disc-shaped conveying body 3 is moved by a mechanism that repeatedly stops and rotates, that is, an intermittent motion mechanism. The rotational movement is performed intermittently.

When making contact with the printing surface of the printing material, the moving speed of the printing surface of the printing material and the surface speed of the printing roll should be made to match, thereby eliminating relative slippage between the two and ensuring that the misalignment is always at the desired exact position. It prints clearly and without any blemishes.
