Description

[Detailed description of the invention] Industrial applications The present invention relates to an electrostatic flocking device.

Prior Art A general drawback of conventional electrostatic flocking devices is that the short fibers to be flocked to the flocked body should not be electrically charged when they are in the storage box that stores the short fibers arranged in the device. but,
During work, charged short fibers get mixed up, which causes the short fibers stored in the storage box to become charged, causing the charged short fibers to adhere to each other and form a clump of short fibers. If this occurs, the hairs will float in the transplanting chamber in the form of clumps, which will cause the hairs to be transplanted to the transplanted body as they are, resulting in the hairs not being transplanted as they should be. However, there is a drawback that hair cannot be properly transplanted into the concave part of a body to be transplanted unless an electrode having a shape that matches the shape is formed and attached to the concave part of the body.

Problems to be Solved by the Invention The present invention eliminates the above-mentioned drawbacks, that is, the floating of aggregated short fibers in the flocking chamber, and allows the finely divided short fibers to float. Even if the grafted body has a concave shape, the electric wire is designed to match the shape of the concave part! A method to solve the problem that would allow neat hair to be formed in the concave part of the grafted body with a concave shape without having to prepare one is to install a filter near the ceiling where an exhaust hole is provided A short fiber receiving net is stretched on the bottom part, and a swingable gas receiving box is arranged, and on the receiving net, first and second electrodes, a flocked body support, and a third electrode are placed. ! Next, the present invention will be described in detail.

The flocking chamber 1 of the flocking device shown in FIG. 1 is made of electrically insulating material. Below the flocking chamber 1, a gas receiving box 3 constituting a gas receiving section is connected to a swing drive source 4, and a receiving net 2 for receiving short fibers fed through a short fiber input port (not shown 2) is stretched over the gas receiving box 3. The short fibers input from the short fiber input port are stored on the receiving net.The receiving net 2 of the short fibers is stretched below the flocking chamber 1. The power receiving box 3, which constitutes the entire installed gas receiving section, is connected to a first power source 1, which is connected via a gas passage 6 to a gas supply source 5 located outside the flocking chamber 1. 7 is housed on a receiving net of short fibers.
It is arranged in the hair transplanting chamber 1 via an insulator so as to be located on x+p. This electrode is of course connected to a high voltage electrostatic generator (not shown).

Another second electrode 8 is provided above the first electrode 7,
It is placed inside the flocking chamber via an insulator.

This second electrode 8 is of course connected to a high-voltage static electricity generator (not shown).

Further, above the second eight electrodes, a grounded flocked body support 9 is placed in the flocking chamber 1 via an insulator.

A third electrode 10 connected to a high-voltage static electricity generator (not shown) is further arranged on the flocked body support 9 in the flocking chamber 1 via an insulator.

A filter is installed near the ceiling of the hair transplanting room, and an exhaust hole 12 is provided in the ceiling.

Next, the operating state of this device will be explained.

First, all of the short fibers are input from the short fiber input port C (not shown) onto the short fiber receiving net 2 in the flocking chamber 1, and the short fibers are placed on the short fiber receiving net 2! Stored in a fully stacked state.

Close the input port above the short fiber input edge. This receiving net 2 is a perforated plate in which minute holes are bored.

On the other hand, a temporary flocked body entrance (J, not shown) is opened in the grounded hair transplanted body support 9 in the hair transplanting chamber 1, and the flocked body 13 is sent in and supported, and the support operation is completed and the ridge flocked body entrance is closed.

Gas supplied from a gas supply source 5 is humidified, and this humidified gas is continuously pressurized from a gas passage 6 into a gas receiving box 3 constituting a gas receiving section disposed below the hair transplanting chamber. and,
The swing drive source 4 is driven to swing the receiving net 2.

By kneading, the laminated layer of short fibers housed in the receiving net is broken and the short fibers are blown up into the flocking chamber, and the blown up short lR fibers are in a floating state within the flocking chamber.

Furthermore, the first electrode 7 is energized with high-voltage static air from a high-voltage static electricity generator, thereby creating an electric field within the hair-planting chamber, which fully energizes the short captive fibers blown up into the hair-planting chamber in a floating state within the hair-planting chamber. Then, the second electrode 8, which fills the flocking chamber 1 with floating short fibers, is energized from a high-voltage static electricity generator.

Since this electrode is supported by the grounded hair-planting object support 9 and placed close to the hair-planting object 13, when energized, an electric field is generated from below between the electrode and the hair-planting object 13, and it is inside the hair-planting chamber 1. The floating short fibers are energized from a high voltage electrostatic generator to the third electrode 10 attached to the lower surface of the flocked body 13 along the lines of electric force created by the electric field.

Since this electrode is also placed close to the flocked object 13 supported by the grounded flocked object support 9, an electric field is generated from above the flocked object 13 between it and the flocked object 13 when energized. The short fibers floating in the flocking chamber 1 adhere to the upper surface of the flocking target 13 along the electric lines of force created by the electric field. When the hair transplantation of the hair transplanted body 13 is completed, open the hair transplantation body outlet (not shown) in the hair transplanting chamber 1 and remove the hair transplanted body 1 from which the hair transplantation process has been completed.
3, and Toride Shun closes it. During the flocking operation, the gas that is blown into the flocking chamber 1 and blown up to the short line M# is filtered through the filter 11 installed on the ceiling. The air is exhausted from the exhaust hole 12. Also filter 11
The short fibers adhering to the can be removed by air jetted from the air nozzle 16.

Since the present invention is constructed as described above, even if the charged short fibers that are once suspended in the flocking chamber fall onto the stacked short fibers on the receiving net 2, the receiving net 2 will not always swing. Gas is continuously blown up from the gas receiving box 3 below the receiving net 2, so the stack of short fibers is constantly broken down by the shaking of the receiving net 2 and the blown up gas, and the gas is continuously blown up from the gas receiving box 3 below the receiving net 2. 2 is made of a perforated plate, so the stack of broken short fibers is blown up together with the gas from various parts of the micropores of the oscillating receiving net, resulting in a lump of short fibers. Therefore, it is blown up in a separated state.

Furthermore, the present invention is configured to use both the so-called up flocking method using the second T group 8 and the down flocking method using the third electrode 10, so that even the concave portion of the concave-shaped flocked body 13 can be The electrode 8 can form an electric field that matches the surface of the recess, and allows fine flocking to occur in the recess. In other words, the short lji! which is biased and floats inside the flocking chamber by the blowing force of the gas and the electric field formed by the first electrode 7! The electric field generated between the third electrode 10 and the flocked body 130 catches the fibers in a down flocking method, and all of the short fibers are electrostatically attached to the concave surface of the flocked body 13.

Incidentally, by horizontally reciprocating the 'fc electrodes, particularly the second and third electrodes 7 and 8, and the temporary hair transplant body supporting body 9 disposed in the hair transplantation chamber 1 during operation of the hair transplantation device, uneven hair transplantation on the hair transplanted object can be prevented. In addition, by using the second and third electrodes as different electrodes and operating them mutually or simultaneously as the same electrode, the second and third electrodes and the second and third electrodes can be operated simultaneously. By changing the direction of the electric field lines generated between the poles, it is possible to change the direction of electrostatic adhesion of the short fibers floating in the flocking chamber, and by this operation,
This solves the problem that until now it was considered difficult to implant hair on deep-drawn molded products. The above-mentioned horizontal reciprocating mechanism for the electrode, the support for the hair-planted body, and the current switching mechanism from the power supply for the electrode K7j can be covered by the prior art. By completely preventing the adhesion of fibers and completely changing the direction of formation of electric lines of force by forming an electric field, hair can be transplanted evenly even on objects with uneven surfaces.

Furthermore, as shown in FIG. 2, the hair removal chamber of the present invention has a loading chamber 17 in which the torn artificial hair body 13 is attached to a device for suspending or placing the torn artificial hair body 9 on the grafted body support 9 disposed in the hair transplantation chamber 1. and a waiting room 18 for sending the hair-covered body attached to the above-mentioned device to the hair-transplanting chamber 1 are arranged on one side, and the other t1411 is provided with a waiting room 18 in which the hair-planted body 13, which has been completely transplanted, is transferred from the hair-planting chamber 1. A room 19 to take out,
A soot unloading room 20 is provided for removing the transplanted body from the above-mentioned device after hair transplantation, and each of these rooms is connected to a transport device (
11, conveyor rail 21] is 17.18. t
, 19° and 20. Since the present invention is constructed as described above, the short fibers do not form clumps in the flocking chamber, and therefore the short wires M do not form what is called a pill. Lift yourself up into the hair transplantation chamber and implant the hair in this condition on the transplanted object.Also, even in the case of a concave-shaped hair transplanted object, short-temperature fibers can be applied evenly by energizing the electrode. ? Hair transplantation is possible.
