Abstract

PURPOSE:To enhance a high speed printing with an accuracy in positioning by continuously rotating a group of printing rollers in a printing machine and a feed-table for feeding goods to be printed at a predetermined speed in a chip type electronic parts printing device. CONSTITUTION:Goods-to-be-printed G supplied onto a carry-in conveyor 9 linearly and in a sequential manner are transferred to grooves 21 defined on an auxiliary ring 8 in a stopped-state due to an air from a nozzle 11 one by one by stoppers 23, 24 lifting up and down alternately. Sequentially, the auxiliary ring 8 is accelerated to become synchronous with respect to a feed table 7 revolving normally, and the goods G are transferred to pockets 20 by air from a nozzle 12. Then, the auxiliary ring 8 is returned to its stopped-state. Simultaneously, the goods G printed by a printing roll 4 are transferred onto a carry-out conveyor 10 by the reversed process. Since the printing roll and the feed table are normally rotated at a predetermined speed, a high-speed printing can be achieved. Also, a high accuracy in printing position as well as a minimization of vibration and noise can be achieved.

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.

Chinozo type electronic components such as chip resistors and chip capacitors are, for example, 1.6U+ wide, 32mm long, and 0.61mm thick.
It is a cubic chip weighing about 10 cm, which is extremely small, but it must be printed to display resistance values, capacitance values, etc.

The object of the present invention is to provide a three-dimensional article printing device that continuously prints by supplying chips to the printing roll of a printing machine accurately and convexly.

In summary, the three-dimensional article printing apparatus of the present invention consists of a printing knoll that continuously rotates at a predetermined angular velocity, and a printing knoll that continuously rotates in synchronization with the printing roll and accommodates the printed product. The ino (feeding disk) and its (71
It has a ring-shaped part that circumscribes the outer periphery of the feeding disk, and a groove is formed between the outer edge and the inner edge of the ring-shaped part to pass through the printed material, and it is possible to maintain the same angular velocity as the feeding disk when in a stopped state. It has an auxiliary ring that repeats the synchronous state lf, and when the printed product is transferred from the carry-in conveyor to the groove of the auxiliary ring gate that is in the stopped state, when the synchronous 1 state is reached, it is transferred from that groove to the above pocket. It is characterized by its composition (transferred and printed).

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an overall perspective view of an embodiment of the present invention, FIG. 2 shows a main part of the embodiment of the invention in a sectional view, and FIG. 3 shows a perspective view.

In the printing machine 1, a roller section 3 containing a printing roller cheek, a printing ink supply device, etc. is provided on the front surface of a vertical substrate 2, and a printing roller 4 is arranged at the lower end of the roller section 3. A synchronous supply section 5 for printing 11 to be printed is disposed below the roller section 3, and on its upper surface 6 there is a supply disk 7 whose outer periphery passes just below the printing roller 4, and a feed disk 7 whose outer periphery passes just below the printing roller 4. An auxiliary ring 8 is provided in contact with I+. The material to be printed is synchronously (carried in to the Jj feeding section: there is a ring hair 9, and the end 0121 is the auxiliary ring 8 glue (time fl
It is installed at a predetermined location of i+.

At a predetermined position C, which is temporally later than the printing position B, there is provided the starting end of a JR delivery system 710 for transporting printed articles. At positions A and C there are provided compressed air nozzles II, 12, 13 and 14 for conveying the substrate, which communicate with an air pump (not shown) or a cylinder.

On the outer circumferential surface of the printing 1''-ru 4, four printing contents are marked by contacting the plate roller four times, for example, during one rotation of the printing τ''-ru. On the outer periphery of the supply disk 7, pockets 20, . Between the glue 1 edge and the inner edge of the auxiliary ring 8, there are formed grooves 2, . The printing 11-ra 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 depending on the light or the bottom. The shaft 17 of the feeding disk 7 and the shaft 18 of the auxiliary ring 8 of the supply section 5 form a concentric double shaft, and the shaft I7 is the driving shaft in the printing press 1 by means of a transmission mechanism that is engaged with the thread + lt l 9. It is engaged with the pocket 20 and is continuously rotated in synchronization with the printing roll so that the circumferential speed of the pocket 20 matches the circumferential speed of the outer periphery of the printing I + - and so that printing is applied to a predetermined location on the printed product. The shaft 18 of the auxiliary ring 8
Let the driving shaft ^4M in the ζ printing press 1 come together through the intermittent drive mechanism 22, and perform intermittent movement in the stop 1-state and the synchronous state fi.). However, as shown in Part 1,
In the C-phase state, it stops completely, and in the synchronous state, it rotates at the same angular speed as the Ih feeding disk 7. However, in the stopped state, as shown in Fig. 3, the stop position is in the state where the general person's pin 1'9 and the groove 21 are aligned, and the synchronized state °C is 41 °C (the pocket of the feeding disc 71). The intermittent drive mechanism 2
2 have been produced. This intermittent drive mechanism 22 is implemented using a so-called 1''-type index.
Can be used as a wall. .

Floor entry: A pair of front and rear stoppers 2 at the end of 1/A9
3 and 24 are provided. The distance between the two stoppers is approximately 1.5 times the length of the printing material. When the wires 25 and 26 are pulled in the direction of the arrow G, each stopper sinks into the hole in the conveyor path, and the tension When no force is applied, the spring force protrudes onto the conveyance path and moves the printed product through the conveyance path.

The wires 25 and 26 are connected to a cam (not shown) which is engaged with a driving shaft in the printing machine 1, and are actuated intermittently to move the article one by one.
This timing (also synchronized with the intermittent movement of the auxiliary ring 8) is used to pass the articles one by one. An air nozzle /L, ]l is provided for transferring air, and a pocket 20 is inserted from the groove 21 at a slightly rotated position.
Air nozzles 12 are provided for transferring articles to. 1. An arc-shaped article restraint 27 is provided between the installation point of the input air horn 12 and the unloading air nozzle 13 to prevent the article from falling out of the pocket 20.
G1 I10 This article holder 27 is printed if the article is printed.

After the auxiliary ring 8 is accelerated, it is transferred from the groove 21 to the pocket 20 in a synchronous state. Then, the article printed by Ell 11:+1-rule 4 is taken out from the conveyor 10 upper 7\ by the direction opposite to that at the time of delivery.

The disadvantage of the present invention is that each roller group in the printing press 1 and the supply disk that supplies the printing IJ-rule/printing material always rotate continuously at a predetermined speed, so the printing speed is faster. However, the printing position accuracy is high, and there is little lift and noise.
The mechanism is simplified. In addition, as shown in the example, when the article is transferred due to the ejection of air, the mechanism is m! 11
