[0010] A conveyor belt is provided by steel or other sheet-like material, and a suction sheet capable of repeatedly holding and releasing a disk is adhered to the surface of the belt, and the belt is wrapped around a driving roller or the like and installed. An object is solved by a disk conveyor type multicolor printing apparatus.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention are shown in the drawings (FIGS. 1, 2 and 5).
Will be described. Supply means 11 for the disk 2 on the conveyor 10, two or more printing machines 12 and a UV dryer 13,
Inspection means 14, discharge means 15, etc. are arranged, and the discs 2 are placed one after another by the supply means 11 on the conveyor 10 intermittently conveyed by the drive roller 16, printed by each printing machine 12, and each UV drying machine 13 is a multicolor printing apparatus for a disk provided to be dried at 13 and inspected by an inspecting means 14 and then ejected out of the conveyor 10 by an ejecting means 15;

A belt 17 of the conveyor 10 is provided by a sheet material such as steel or the like, and a suction sheet 18 capable of repeatedly holding and releasing the disk 2 is adhered to the surface of the belt 17.
6 is a conveyor-type multicolor printing apparatus P ₁ of the disc which is provided by turning over the roller 19 or the like.

In the above apparatus P _1, the belt 17, although steel is other thin and flexible, tensile strength, provided with a small sheet-like material stretch changes due to temperature, etc., the suction sheet 18, the surface of the belt 17 The entire surface (illustrated example), or an evenly spaced position where the disk 2 is placed, or the belt 1
7 are adhesively installed on the surface of a tray (not shown) installed at equal intervals on the surface.

The adsorbing sheet 18 is a sheet-like material whose surface has adsorbing or sticking properties so that the disc 2 can be repeatedly adsorbed (adhered) and peeled off by its adsorbing or sticking force. Any suitable material can be used. For example, "Removable foam sheet" (manufactured and sold by Dainippon Ink and Chemicals, Inc.)
A flexible and resilient synthetic resin foam (foam) layer 18b having countless minute (micron unit) suction cup-shaped recesses 18c over the entire surface of the synthetic resin base film 18a
And has a strong attraction to a smooth flat surface of the disk 2 and a strong suction force due to the collective action of all the suction cup-shaped recesses 18c against the force to peel off all the attraction surfaces at once. Although the suction sheet 18 is peeled from a part, the suction force of each suction cup-shaped recess 18c is small, so that the suction sheet 18 can be peeled with a relatively weak force, and can repeatedly perform the suction and peeling action described above. Is preferred, but the present invention is not limited to this suction sheet.

The driving roller 16 for driving the belt 17 of the conveyor 10 is driven by a motor having functions of automatic high-precision speed control and positioning, such as a motor having an absolute encoder function, so that the conveyor 10 can be moved to a set dimension with high accuracy. Provide for intermittent transport. "Motor with absolute encoder function" Resolution (P / rev)
Is a high-resolution built-in optical encoder motor of about 500 to 1,000,000, for example, "Dynaserve DM Motor"(trademark; Yokogawa Precision Co., Ltd.).

[0016]

Features of the present invention, effects order that the conveyor type, compared with the conventional turntable, the length dimension of the device P ₁ is longer, the width can be narrowed to 1/2 or less. For example, in the case of a four-color printing apparatus, the length is about 5500 mm and the width is about 1000 mm. Even if the number of colors (the number of prints or the like) is increased or decreased, it is only necessary to change the length.

[0017] As in FIG. 2, was placed 4-color printing apparatus P ₁ of the conveyor-type four spaces of a conventional same area as the four-color printing apparatus P ₂ installed four turntable of FIG. 3 If the width of the device P ₁ can be or placed Haraawase or close the one side wall for a narrow, also, it is possible to work from one side narrower, but the operator unexpected must move the length direction device It is not necessary to move around the entire circumference of the device, so that the installation space and the working space of the device can be remarkably reduced as compared with the related art. 2 and 3, the width of the work space is set to 1000.
mm.

If a thin sheet-shaped steel belt is used as the belt 17, for example, it is thin and flexible, so that it can be easily wrapped around a driving roller or the like, and a high-precision flat surface can be formed on the surface of the conveyor. The suction sheet 18 is bonded and laid, and a disc can be suction-held and conveyed to the suction sheet without a tray to perform screen printing, drying, and the like.

It is long but narrow (eg, 300 mm wide)
) And a thin (eg, 0.1 to 0.15 mm) belt, the driving force is small, and a motor having a high-precision control function can be used.
High precision printing can be performed. In addition, the number of printing machines (number of colors)
There is no great difference in the required driving force even if is increased or decreased, so that the same driving motor can be used. In this regard, the turntable type
With the increase in the diameter of the turntable due to the increase in the number of colors, there is a great difference from the need for a larger and larger output motor.

Adhesive sheets may be adhered and installed at equal intervals (for example, every 150 mm) at the entire surface of the belt or at each disc mounting position, or at the surface of a tray installed at equal intervals on the belt, or at other positions. The disk is adsorbed, held and transported by the adsorbing sheet, so that a complicated and expensive vacuum pipe installed in each tray in a conventional turntable type apparatus and a control device therefor are not required, and the apparatus is accordingly reduced. Costs can be reduced.

As described above, according to the conveyor type printing apparatus of the present invention, the installation space and working space of the apparatus can be significantly reduced as compared with the conventional turntable type apparatus.
The burden on the operator can be reduced, the device is small and simple, the driving force is small, and a large cost reduction can be realized by eliminating the need for a vacuum pipe and its control device.
