Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for simultaneously and accurately feeding a large number of printing materials to a printing position when printing or painting electrical printed circuits, small parts, name plates, etc.

For screen printing such as printed wiring of electrical parts and silver coating, even if the printing material is small, it can be placed on a single printing stand, or the printing stand can be made into a turntable, and the printing material can be automatically fed to a fixed position by suction. However, this method is extremely inefficient.

An improved version of this uses a large screen, arranges the printing material on a plate-like attachment with a recess for placing the printing material so that it matches the printing position, and places it on the printing table to print a large number of pieces. A method of simultaneous printing has been proposed, but this method requires a lot of work to accurately arrange a large number of printing materials at predetermined positions on the attachment, and if the printing material is thin, such as ceramic, it is likely to be damaged. Since this method requires care in handling, the effect of simultaneous printing on a large number of pieces cannot be achieved.

The present invention is capable of quickly and accurately arranging and supplying a large number of printing materials to a printing position.Explaining the embodiment with reference to the attached drawings in which the printing material a is a circular ceramic thin plate, as shown in FIG. As shown in CD, a large number of supports 2 are arranged on a flat plate-shaped printing material loading table 1 to support the printing material a in a predetermined position by arranging a large number of supports 2 that contact the outer periphery of the printing material a and support a large number of sheets in a fixed position. do it like this.

In the figure, a large number of stacked printed materials a are arranged in a staggered manner, and each printed material is supported by three pillars 2, with adjacent printed materials sharing the pillars 2.

The suction cup 3 corresponding to the above-mentioned loading table 1 is provided with a large number of receiving holes 4 into which the respective supports 2 are fitted, and suction holes 5 for suctioning the printing material a are arranged corresponding to the positions of the printing materials on the loading table 1. An appropriate number of suction holes 5 are formed in the suction cup 3, and each suction hole 5 is connected to an intake chamber 6 formed in the suction cup 3.
The intake chamber 6 is connected to a flexible pipe 7, as shown in FIG.
The loading platform 1 and the suction cup 3 are connected to an outside air or vacuum pump 9 via a switching knob 8, and a positioning shaft 10 and a guide hole 11 are provided on the loading platform 1 and the suction cup 3 to determine their relative positions.

FIG. 2 shows an example of a printing machine, where 12 is a printing table supported by a piston 13 so as to be able to move up and down, 14 is a printing screen,
Reference numeral 15 denotes a squeegee that prints by sliding on the screen, and the above-mentioned screen printing machine is a known one.

In the above configuration, a large number of printing materials are arranged in a stacked manner using the support column 2 on the loading table 1, and the suction cup 3 is lowered so that the positioning protrusion shaft 10 and the guide hole 11 are fitted together. is placed on the printing material a on the loading table 1.

In this state, the support 2 and the receiving hole 4 also fit together, so when the suction chamber 6 is connected to the vacuum pump 9 by the switching knob 8, the top layer of the printing material a is suctioned as arranged, so the suction cup 3 is pulled up, rotated 180 degrees, turned over, and placed on the printing table 12 at a predetermined position, the printing table 12 is raised to perform printing or painting, and the printing table is lowered and the suction is released by the switching knob 8. For example, the printing material a can be easily removed from the suction cup 3.

The above operation can be performed manually, but the suction cup 3
It is also possible to automatically perform printing in synchronization with printing by supporting it with a mechanism that can move it up and down, back and forth, and even turn it upside down.

As described above, according to the present invention, it is possible to simultaneously supply a large number of printing materials ak in a single operation and perform multiple printing, and the printing materials a are easily and accurately arranged and superposed at the printing position by the support 2, By sucking and feeding one sheet of the arranged top layer substrate at the same time, the function of multiple printing can be fully demonstrated, and the arrangement and feeding of the printing substrate can be done quickly and reliably without any trouble. If drying or post-processing is required after printing, the printed material can be transferred from the suction cup 3 to a drying table, but if this is difficult, as shown in FIG. The tray 17 provided with the
After placing the printed matter that has been sucked on the tray 17 without reversing it, the vacuum suction device of the printing table is activated and at the same time the suction of the suction cup 3 is released, the printed matter is secured on the tray 17. Therefore, by retracting the suction cup 3 from above the printing table, performing the required printing, and releasing the suction action of the printing table, the printed material can be moved all at once to the next process such as drying while remaining on the tray. By preparing an appropriate number of trays, continuous work can be carried out without any problems.

Although the above embodiments have been described with reference to circular printing substrates, it is of course possible to arrange printing substrates of rectangular, triangular or other modified shapes at predetermined positions as shown in FIGS. 5 and 6.
