Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-dimensional article printing apparatus, and is particularly applicable to a printing apparatus for chip-shaped articles.

Chip-type electronic components such as chip resistors and chip capacitors are, for example, 1.6 mm wide, 3.2 mm long, and 0.6 mm thick.
It is a cubic chip weighing just over 10 mg, which is extremely small, but it must be printed to display resistance, capacitance, etc.

An object of the present invention is to provide a three-dimensional article printing apparatus that can accurately and efficiently supply such chip-shaped electronic components to a printing roll of a printing machine and continuously print them.

In summary, the three-dimensional article printing device of the present invention includes a printing roll that continuously rotates at a predetermined angular velocity, and a supplying device that continuously rotates in synchronization with the printing roll and has a pocket opening at the outer edge for accommodating the printed item. It has a disk and a ring-shaped part circumscribing the outer periphery of the supply disk, and a groove for passing the printed product is formed between the outer edge and the inner edge of the ring-shaped part. It has an auxiliary ring that alternately repeats a synchronous state with the same angular velocity, and after transferring the printing material from the conveyor to the groove on the auxiliary ring that is in a stopped state, when the synchronous state is reached, the product is transferred from that groove to the above pocket. It is characterized by being configured so that it can be transferred and printed.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an overall perspective view of an embodiment of the present invention, and FIG. 2 shows a cross-sectional view of main parts of an embodiment of the present invention.
It is shown in a perspective view in FIG.

The printing machine 1 includes a roller section 3 that includes printing rollers, a printing ink supply device, etc. in front of a vertical substrate 2.
is provided, and a printing roller 4 is disposed at the lower end thereof. A synchronous supply section 5 for printing material is arranged below the roll section 3, and on its upper surface 6 there is provided a supply disk 7 whose outer periphery passes just below the printing roller 4 and an auxiliary ring 8 in contact with the outside thereof. . There is a carry-in conveyor 9 for carrying the printing material to the synchronous supply section, and its terminal end is located at a predetermined position A on the outer periphery of the auxiliary ring 8, which is temporally earlier than the printing position B. At a predetermined position C, which is temporally later than the printing position B, the starting end of a carry-out conveyor 10 for carrying out printed articles is provided. At positions A and C there are compressed air nozzles 11, 12, 1 for conveying the printing substrate.
3 and 14 are provided and communicate with an air pump (not shown) or cylinder.

Four printed contents are marked on the outer peripheral surface of the printing roller 4 by contacting the plate roller four times, for example, during one rotation of the printing roller. On the outer periphery of the supply disk 7, there is a pocket 20 for storing the article to be printed.
20 is formed with an opening at the outer edge. Grooves 21 are formed between the outer and inner edges of the auxiliary ring 8, through which the printed product slides. The printing roller 4 engages with a driving shaft within the printing press 1 and is driven to rotate continuously at a predetermined angular velocity. This predetermined angular velocity can be increased or decreased as desired. The shaft 17 of the supply disk 7 of the supply section 5 and the shaft 18 of the auxiliary ring 8 form a concentric double shaft, and the shaft 17 engages with a driving shaft in the printing press 1 by a transmission mechanism that engages with a gear 19. pocket 2
The circumferential speed at 0 and the circumferential speed at the outer circumference of the printing roller match,
Moreover, it is driven to rotate continuously in synchronization with the printing roll so that printing is applied to a predetermined location on the printing object.
The shaft 18 of the auxiliary ring 8 is engaged with the driving shaft in the printing press 1 via an intermittent drive mechanism 22, and performs intermittent motion in a stopped state and a synchronous state. That is, as shown in FIG. 4, the stopped state is completely stopped, and the synchronous state is rotated at the same angular velocity ω as the supply disk 7. Furthermore, in the stopped state, the carry-in conveyor 9 and the groove 21 are aligned with each other, as shown in FIG. The intermittent drive mechanism 22 is manufactured so that the This intermittent drive mechanism 22 can be implemented using a so-called rotary index.

A pair of front and rear stoppers 23 and 24 are provided at the terminal end of the carry-in conveyor 9. The distance between the two stoppers is about 1.5 times the length of the printing material. Both stoppers are wires, and when the wires 25 and 26 are pulled in the direction of the arrow, they sink into the holes in the conveyor path, and when no tension is applied, they protrude onto the conveyor path by the force of the spring to prevent the printing material from passing through. do. The wires 25 and 26 are actuated alternately and intermittently by a cam (not shown) that engages with the driving shaft in the printing press 1 to pass the articles one by one, and this timing is synchronized with the intermittent movement of the auxiliary ring 8. are doing. Above the terminal end of the carry-in conveyor 9, an air nozzle 11 is provided for transferring the article from the terminal end to the groove 21 on the auxiliary ring, and at a slightly rotated position from there, the article is transferred from the groove 21 to the pocket 20. An air nozzle 12 is provided for this purpose. An arcuate article restraint 27 is provided between the installation point of the carry-in air nozzle 12 and the carry-out air nozzle 13 to prevent articles from falling out of the pocket 20. This article retainer 27 also prevents articles from adhering to the printing roll 4.

Air nozzles 13 and 14 are disposed in the discharge section that transfers the printed articles to the discharge conveyor 10, and a chute 2 is installed between the auxiliary ring 8 and the discharge conveyor 10.
8 is provided. The air nozzle 13 is inserted into the pocket 20 of the supply disc when the auxiliary ring 8 is in the synchronized state.
The air nozzle 14 is provided at a position that coincides with the groove 21 when the auxiliary ring 8 is in a stopped state.

In such a device, the printing materials G that are fed in series onto the carry-in conveyor 9 are discharged one by one by stoppers 23 and 24 that move up and down alternately, and are transferred to the groove 21 of the stationary auxiliary ring 8. Then, the auxiliary ring 8 is accelerated and then transferred from the groove 21 to the pocket 20 in a synchronous state. Then, the articles printed by the printing roll 4 are taken out onto the carry-out conveyor 10 by a process reverse to that at the time of carry-in.

According to the present invention, each roller group in the printing press 1 and the supply disk that supplies the printing material to the printing roll are constantly rotating at a predetermined speed, so that not only the printing speed is high but also the printing position is High precision, low vibration and noise, and simplified mechanism. Also,
As shown in the embodiment, if the article is transferred by blowing air, the mechanism becomes simple.

In the present invention, the carrying-in conveyor 9 is provided with, for example, three rows of carrying-in paths, and the grooves 21 on the auxiliary ring, the pockets 20 on the supply disk, and the plate positions on the printing rolls can be configured as a group of three. can.
