Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a nailhead painting apparatus according to a preferred embodiment of the present invention.

Referring to FIG. 1, the nailhead painting apparatus of the present invention includes a supply unit 10, a transfer unit 20, a transfer unit 30, a drying unit 50, and a storage unit 70.

The supply unit 10 is a unit for supplying nails in a line to the nailhead painting apparatus of the present invention. Although not shown, a cylindrical feeder is provided at the front end of the supply part. The cylindrical feeder feeds nail to the feeder in a row.

The supply portion 10 is formed of an elongated tube having an incised groove, and the nail is naturally lowered by gravity while being held in the incised groove. An inclined guide (12) inclined at a predetermined angle is formed at the distal end of the supply part. The inclination guide 12 is a portion for stably supplying the nail supplied from the supply unit to the rotating disk 22.

The transfer unit 20 is a unit for transferring the nail from the supply unit 10 to the transfer unit 30. That is, it is a portion for feeding the nail by the timing belt 32 in the feeding section 10 stably to the feeding section 30.

FIG. 2 is a partially enlarged view of a nailhead painting apparatus, which is a perspective view showing a supply unit, a transferring unit, and a transferring unit, and FIG. 3 is a schematic view of a transferring unit of a nailhead painting apparatus according to a preferred embodiment of the present invention.

2 and 3, the conveyance transmitting portion 20 includes a disk 22 and an auxiliary roller 24. [

The circular plate 22 has a structure in which a plurality of grooves 23 are formed at regular intervals on the edges so that the nails are spaced apart from one another at regular intervals while being rotated. That is, while the original plate rotates, the nails supplied from the supply unit are spaced apart at regular intervals and transferred to the transfer unit.

The auxiliary roller 24 is formed on one side of the disk and is a portion for holding the nails on both sides and supplying the nails to the conveyance belt of the conveyance portion. In other words, the transfer unit 20 is transferred to the transfer unit 30 stably with the nail being spaced apart from each other by the disc 22 and the auxiliary roller 24.

The transfer unit 30 is connected to the supply unit 10 and transfers the nails supplied from the supply unit in a line. On the upper part of the transfer part, brushes 46, 46a, 46b of the painting part are provided to paint on the nail head. That is, as the nail moves along the transfer part, painting of the nail head is performed by the brush of the painting part. The belt of the conveying portion is preferably made of a timing belt 32 so that accurate and stable conveyance is possible.

Next, the painting unit 40 provided on one side of the transfer unit is a part for painting the head of the nail. The painting section 40 performs painting of the nail head by the brush 46. Fig. The plating liquid supplied to the brush is supplied by the plating liquid tank 41. A zinc plating solution for zinc plating may be supplied.

FIG. 4 is a partial enlarged view of a nailhead painting apparatus according to a preferred embodiment of the present invention, which is a perspective view of a painting unit, and FIGS. 5, 6 and 7 are schematic views of a painting unit of a nailhead painting apparatus.

The painting unit 40 of the present invention includes a plating liquid tank 41 to which a plating liquid is supplied, a metering pump 43, a transfer pipe 43, and a brush 46.

The plating liquid container 41 is a container containing a plating liquid for plating the nail head. That is, it corresponds to the plating solution reservoir.

The metering pump 42 is connected to the plating liquid tank 41 to supply a constant amount of the plating liquid. The reliability of the painting operation can be secured only when a predetermined amount of plating liquid is supplied by the metering pump. If the supply of plating liquid is excessive or inadequate, plating may be less or the drying may not be complete during the drying process.

The transfer pipe (43) is connected to the metering pump to supply the plating liquid to the brush. And the plating liquid is transferred through the inside. A hole 44 is formed in the side surface of the end, and the plating liquid is transferred to the brush 46 through the hole 44.

The brush 46 is in close contact with the transfer pipe. This is to receive the plating liquid through the hole 44 of the transfer tube. The supplied plating solution is applied to the nail head through a brush. That is, the painting is performed.

As shown in the figure, the brush of the present invention preferably consists of two brushes, that is, a primary brush 46a and a secondary brush 46b according to the painting sequence. This is to increase the reliability of the painting operation. It is preferable that the amount of the plating liquid supplied to the primary brush is larger than the amount of the plating liquid supplied to the secondary brush. To this end, the hole of the transfer tube adjacent to the primary brush must be larger or wider than the hole of the transfer tube adjacent to the secondary brush. In the figure, there are two holes in the transfer pipe adjacent to the primary brush, and one hole in the transfer pipe adjacent to the secondary brush. As a result, the amount of the plating liquid supplied to the primary brush becomes larger than the amount of the plating liquid supplied to the secondary brush.

If the hole of the transfer tube is in close contact with the brush, there is a danger that the brush will spread over time. To this end, the support 47 is supported on the opposite side of the transfer tube with respect to the brush. In other words, the support table 47 is provided on the opposite side of the transfer tube with respect to the brush, so that the plating liquid adheres well to the brush and prevents the brush from spreading

When the nail head is painted, the drying process is performed in the drying unit 50. The drying unit is not made in another apparatus but is continuously performed in one system (apparatus).

In the present invention, a first preheating dryer 52 having a relatively low temperature and a second high temperature dryer 54 are provided.

The primary preheating / drying unit 52 is installed at the upper end of the conveying unit and dried on the conveying unit. That is, a heater is installed at the upper end of the conveyance unit, and drying is performed, and the temperature is dried at a temperature between approximately 100 and 200 ° C. At this relatively low temperature, since the timing belt 32 of the conveyance portion can withstand, the first preheating drying is performed on the conveyance portion.

After primary preheating and drying, high-temperature secondary drying is performed in the second high-temperature drying section (54). A near-infrared heater is installed for high-temperature drying. The temperature of the high temperature drying part is dried at a temperature higher than that of the primary preheating drying part at 200 to 300 ° C. This temperature is a temperature at which the timing belt of the conveying portion is hard to withstand. Therefore, a metal belt is used at the lower end of the second high temperature drying section. That is, in order to transport the nail in the second high-temperature drying unit, a mesh metal belt 60 made of metal for enduring high temperature is installed in the lower portion of the second high-temperature drying unit. The mesh metal belt 60 is a metal mesh belt, preferably without a hole or with a very small structure, and thus an H type mesh belt or a G type mesh belt is used.

The nails aligned in line at the transfer section are placed on top of the mesh metal belt. Preferably, the anti-sag support roller 62 is provided at the bottom center of the mesh metal belt. This is because the metal mesh belt is made of a metal material, and its weight is high, and there is a risk that the metal mesh belt is deformed downward. To prevent this, a sag prevention support roller 62 is installed.

The dried nails are stored in the storage unit 70. The storage portion is provided at the end of the mesh metal belt (60).

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention by those skilled in the art. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to illustrate them. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of the claims should be construed as being included in the scope of the present invention.
