Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a three-dimensional article printing device, and more particularly to alignment and discharge of a chip-shaped article printing device.

(Problems with conventional technology) Chip-type electronic components such as chip resistors and chip capacitors are three-dimensional chips with a width of 1.6 mm and a thickness of 0.6 mm, and although they are extremely small, they can display resistance values, capacitance values, etc. There is a need to.

Conventionally, in a three-dimensional article printing device, a printing material is placed from a printing material supplying device in a groove of a conveying ring rotating at a predetermined speed, and the printing material is conveyed to a printing device by the conveying ring. After printing, the product is transported to the location where the transport conveyor is installed, and the material to be printed is transferred from the groove of the transport ring to the transport conveyor using a transport means such as an air nozzle, and then transferred to the drying device by this transport conveyor. The printing ink on the printing material was dried using a drying device, and then the printing material was stored in a predetermined case.

However, when transferring the printed product from the groove of the conveyor ring to the conveyor, the air from the air nozzle is vigorously ejected from the groove of the conveyor ring to the conveyor. They have the disadvantage that they are disposed in pieces or come off the conveyor.

(Object of the Invention) The present invention was proposed in order to improve the above-mentioned drawbacks, and provides an alignment and discharge device for a three-dimensional article printing apparatus that aligns and sequentially discharges printed articles from a conveyor ring to a conveyor. It is an object.

(Embodiment of the Invention) The present invention will be described below based on an embodiment shown in FIGS. 1 to 4.

A is a three-dimensional article printing device, which has a pedestal B for a fixed disk 1 on a base A1, a fixed disk 1, a conveying ring 2,
It is equipped with a printing material supply device 3, a printing device 4, an alignment and discharge device 5, a conveyor 6, a drying device 7, and the like.

The conveyor ring 2 has a ring-shaped portion 2a circumscribing the fixed disk 1, and a plurality of grooves 2b for arranging the printing material C are formed in the ring-shaped portion 2a at regular intervals.

The conveyance ring 2 is provided so as to rotate at a predetermined speed in synchronization with a motor built in the three-dimensional article printing apparatus A using a transmission mechanism.

In the printing material supply device 3, a supply arm 3b is provided on a supply section 3a that supplies a printing material C, and the supply arm 3b is connected to a ring with a supply path 3c provided in the supply arm 3b at point A. The groove portions 2b of the shaped portion 2a are opposed to each other, so that the tip portion faces the ring-shaped portion 2a.

The printing material supply device 3 supplies the printing material C from a supply section 3a to a supply path 3c using air from an air nozzle.

Since the printing material C is pressed toward the ring-shaped part 2a by air in the supply path 3c, when the groove 2b and the supply path 3c correspond to each other, it is pushed out and disposed in the groove 2b, and is pushed out to the ring-shaped part 2b. The image is conveyed to the printing device 4 by the printer.

The printing device 4 is provided with a roller section 4b having built-in printing rollers on the front surface of the base 4a.
At the lower end of this roller portion 4b is a printing roller 4c.
is disposed, and this printing roller 4c is connected to the groove 2 of the conveying ring 2 passing directly under the printing roller 4c.
It is set so that printing can be performed on the printing material C disposed at b, and four printing contents are written on the outer circumferential surface by contacting the plate roller four times during one rotation. It's getting old.

The printing roller 4c is rotated in synchronization with a motor built in the three-dimensional article printing apparatus A by a transmission mechanism via the driving shaft of the printing apparatus 4, and the rotational speed of the conveying ring 2 and the rotational speed of the printing roller 4c are controlled by a transmission mechanism. It is provided so that it can be adjusted and printed at a predetermined location on the printing object C.

The printing device 4 has a printing roller 4 at the point
The printed article C is printed by c, and the printed article C is conveyed to point C by the conveying ring 2.

At point C, the ring-shaped portion 2a of the conveying ring 2
The printed product C is transferred from the groove 2b to the conveyor 6.
An air nozzle 8, which is a transfer device for transferring, is provided, and an alignment device 5 is provided between the transfer ring 2 and the transfer conveyor 6.

The aligning and discharging device 5 is provided on a pedestal B, and guide pieces 5a and 5b for guiding the printed article C are provided on both sides of the ejecting path 5a. A notch 5e is formed in one guide piece 5b, and a transfer rubber roller 5d connects a part of the peripheral wall to the discharge path 5c in the notch 5e. The distance L1 between the peripheral wall exposed to the discharge path 5c of the guide piece 5b and the transfer rubber roller 5d is defined as the width L2 of the printed product C.
It is designed to be slightly smaller.

The transfer rubber roller 5d is provided so that the rotational power of a motor for the transfer rubber roller 5d built in the three-dimensional article printing apparatus A is transmitted by a transmission mechanism, for example, a belt, and is normally rotated in the two directions of the arrow. .

Printed product C printed by printing device 4
At point C, the air is vigorously transferred from the groove 2b of the conveyor ring 2 to the discharge path 5c of the alignment and discharge device 5 by the air ejected from the air nozzle 8, and collides with the transfer rubber roller 5d.
Due to the collision, the printing object C loses its momentum and comes to a stop.

The printed product C that has stopped in contact with each other is arranged such that the distance L1 between the guide piece 5a and the transfer rubber roller 5d is smaller than the width L2 of the printed product C, and the transfer rubber roller 5d is rotated in the direction of arrow N. Therefore, it is conveyed to the conveyor 6 while being pressed toward the guide piece 5a by the peripheral wall of the rubber roller 5d for conveyance.

The printed product c conveyed by the transporting rubber roller 5d comes into contact with the printed product C1 that was conveyed earlier during conveyance, and the printed product C is transported by the conveyor 6.
While being transferred to the side, the previous printing object C1 is pushed.

Transfer conveyor 6 from transfer rubber roller 5d
Since the printed articles C1, C2, and C3 on the sides are arranged in a line, the printed article C transferred to the discharge path 5c is pushed out by the printed article C1. The first printing object C3 is pushed out, and when the transfer of the printing object C is completed, the first printing object C3 is pushed out onto the transport conveyor 6.

By repeating this operation, the printed products C will be sequentially discharged from the transport ring 2 to the transport conveyor 6.

The transport conveyor 6 transports the printing materials C discharged from the discharge path 5c of the alignment discharge device 5 to the drying device 7.

The drying device 7 passes the printing material C carried by the conveyor 6 into the case 7a, and
The printing ink on the printed product C is dried by a drying lamp installed in a.

Then, the printing material C whose printing ink has been dried by the drying device 7 is transported by the transport conveyor 6 and stored in a predetermined case.

(Effects of the Invention) As described above, the present invention provides an alignment and discharge device between the conveyor ring and the conveyor,
Since the printing materials are aligned by the transfer rubber rollers of the alignment and discharge device and sequentially discharged onto the transport conveyor, it is not possible to arrange the printing materials separately on the transport conveyor or to separate them from the transport conveyor. This has the practical effect of being able to be arranged in a line on a conveyor without causing any damage.
