Description

  The present invention relates to an electrostatic flocking device.

BACKGROUND ART Products that have been subjected to electrostatic flocking (flocking products) are widely used from various industrial products to daily necessities such as automobile interior materials, air conditioner parts, and miscellaneous goods parts. At present, electrostatic flocking is performed by automated devices for products manufactured in large quantities, such as coin boxes (coin purses built into dashboards) that are automobile interior materials, and louvers that are used in air conditioner coolers. (See Patent Document 1). However, most of the products (for example, posters and ornaments) that are not compatible with mass production as described above are electrostatically implanted by hand. On the other hand, regardless of whether it is automatic or manual work, it is necessary to apply an adhesive to the planted body prior to flock (nylon fiber, short fiber, pile) planting to produce a planted product. The application method is roughly classified into two types. The first method is a method in which an adhesive is applied to the front surface of the hair transplanted body, and is generally applied by spraying. The other is a method by screen printing. The screen printing method is a method in which an adhesive is applied instead of printing ink used for normal printing.
JP 2003-305386 (see paragraph 0011, FIG. 1)

  Here, in the application of the adhesive by spraying, when partial hair transplantation is performed on the planted hair body, that is, when the adhesive is partially applied, a portion not to be implanted (a non-planted portion, that is, an adhesive is applied) Masking work is necessary to hide the part that is not). Screen printing tends to be a uniform design because it takes time to create the shape of the flocked portion or non-flocked portion that is to be created by using it, that is, it takes time to create a so-called block composition. . The problem to be solved by the present invention is to apply an adhesive with a desired pattern, even if it is a simple design as well as a complicated design, without having to create a template each time. It is to make it possible to perform electric flocking.

  In order to solve the above-described problems, the present invention has the following configuration. It should be noted that the definition of terms used in the description of the invention according to any claim is applicable to the invention according to other claims as long as it is possible in nature.

(Characteristics of the invention described in claim 1)
An electrostatic flocking device according to the invention described in claim 1 (hereinafter referred to as “flocking device of claim 1” as appropriate) includes image input means (for example, a scanner, CAD) for inputting image data, and the image input. Based on the image data input from the means, an adhesive application means for applying an adhesive to the hair transplantation body, and a hair transplantation means (flocculation method) for electrostatically flocking flocks on the hair transplantation body to which the adhesive is applied Are, for example, an up type, a down type, and a side type), and a control means for controlling the adhesive application means and the flocking means.

  According to the flocking device of the first aspect, the adhesive can be applied to the flocked body based on the image data input from the image input means. Since the adhesive pattern based on the image data can be drawn, it is not necessary to create a printing plate necessary for the adhesive coating method using the screen printing method. For this reason, it is possible to easily perform pattern creation, pattern switching, change, and the like. A variety of patterns can be selected and used as desired. Whether it is a simple pattern or a complex pattern, there is no change. Therefore, uniform patterning is prevented, and electrostatic flocking with a variety of patterns is realized. After applying the adhesive, the flocking means performs flocking. The flying flock is attracted to the to-be-grafted body by electrostatic force, and adheres to the adhesive pattern by the action of the adhesive. The electrostatic flocking work is completed by drying the adhesive after the flock is attached.

Further, the control means causes the dispenser to discharge the adhesive when the distance between the nozzle and the hair transplant body falls below a predetermined distance based on the hair transplant body detection signal, and the nozzle and the hair graft When the distance from the body exceeds a predetermined distance, the dispenser is made to perform adhesive suction instead of discharging the adhesive.

  According to the flocking device of claim 4, in addition to the effects of the flocking device of claim 2 or 3, when the nozzle approaches the to-be-grafted body, that is, when the distance falls below a predetermined distance, the discharge of the adhesive is started. On the contrary, when it is far away, that is, when it exceeds a predetermined distance, the discharge of the adhesive is stopped and the suction of the adhesive is performed. The distance sensor detects the predetermined distance. The control device moves the nozzle away from the planted body when the dispenser stops discharging the adhesive, and bonds when the distance between the planted body and the nozzle exceeds a predetermined distance due to the movement. Let the agent suck. Adhesive suction is mainly for preventing a drop in surplus adhesive when discharging is stopped and pattern thickening due to application of surplus adhesive when starting discharging. That is, in order to remove excess adhesive that causes dropping and pattern thickening, suction is performed in the nozzle. As described above, at the end of drawing (coating) an arbitrary line (pattern), the excess adhesive is slightly sucked, so that uniform line drawing can be performed at high speed while preventing dripping of the adhesive. .

  The best mode for carrying out the present invention (hereinafter referred to as “this embodiment” as appropriate) will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of an electrostatic flocking device. FIG. 2 is a perspective view of the flocking gun and the flocking moving mechanism. FIG. 3 is a perspective view of a plurality of flocking guns and a flocking moving mechanism.

(Schematic structure of electrostatic flocking device)
Please refer to FIG. 1 and FIG. The electrostatic flocking device 1 is generally composed of three components: an image input unit 3, an adhesive application unit 5, and an electrostatic flocking unit 7. The image input unit 3 functions as an image input unit for inputting image data. The adhesive application unit 5 is an adhesive application unit for applying an adhesive to the hair graft based on the image data obtained through the image input unit 3. The electrostatic flocking unit 7 is a flocking means for electrostatic flocking flocks (nylon fibers, short fibers, piles) on a flocked body to which an adhesive is applied. Details will be described in the following section.

(Configuration of image input unit)
For example, the image input unit 3 reads an image pattern 101 a depicted on a medium 101 such as paper shown in FIG. 1 from the scanner 11, and inputs image data to the computer 13 by CAD (Computer Aided Drawer). A device (instrument) for inputting image data. The computer 13 or the like when a part or all of necessary image data is read or downloaded from a CD, MD, or other magnetic medium, or from a communication network such as the Internet, also corresponds to the image input unit in the present application. . Note that the computer 13 is provided with a function as a control means, which will be described later, as well as a part or all of the function of the image input unit 3 as described above.

(Configuration of adhesive application part)
The adhesive application unit 5 includes a nozzle 19 for discharging the adhesive G shown in FIG. 1, a dispenser 21 that can supply the adhesive G to the nozzle 19, and can also be sucked (described later), and the nozzle 19. A three-axis table 23 for relative movement, a distance sensor 25 for detecting the distance between the nozzle 19 and the hair transplant body 111, and a control means for controlling the dispenser 21 and the three-axis table 23 And the computer 13 functioning as a general configuration. The nozzle 19 includes a nozzle body 19a and a tip 19b protruding from the nozzle body 19a, and a flow path 19c for moving the adhesive G is formed inside. The flow path 19c communicates with the adhesive supply port (not shown) of the dispenser 21 via the hose 20. The shape of the nozzle 19 and the inner diameter of the flow path 19c are closely related to the viscosity of the adhesive G, the wire diameter of the applied adhesive G, and further, for example, the material and shape of the hair transplant body 111 etc. It may be set as appropriate so as to enable the desired application.

  Next, the three-axis table 23 will be described. The three-axis table 23 includes a table main body 23a, a Y-axis movable part 23c that moves in the Y-axis direction (the thickness direction in FIG. 1) with respect to the table main body 23a when viewed from the front of FIG. The X-axis movable part 23b attached to be movable in the X-axis direction (left-right direction in FIG. 1) relative to 23c, and the Z-axis movable part 23b is movable in the Z-axis direction (vertical direction in FIG. 1). Z-axis movable part 23d attached to the. The nozzle 19 is attached to be movable up and down together with the Z-axis movable portion 23d. The table body 23a in the present embodiment is capable of placing a hair transplant body on the upper surface thereof, and the X-axis movable portion 23b, the Y-axis movable portion 23c, and the Z-axis movable portion with respect to the placed hair transplant body. By moving each of 23d, the three-dimensional adhesive can be applied to the hair to be transplanted. That is, the triaxial table 23 functions as an application moving mechanism for moving the nozzle 19 relative to the hair transplant body. Two-dimensional (planar) movement is sufficient if only the adhesive is applied to a sheet-like hair transplant body such as the hair transplant body 111 shown in FIG. 1, but in this embodiment, it is also adhered to a three-dimensional hair transplant body. It is configured to be three-dimensionally movable so that the agent can be applied. In addition, although the said table main body 23a is comprised so that the to-be-grafted body 111 may be hold | maintained horizontally (it mounts), it is comprised so that this can be hold | maintained vertically, or it is comprised so that it can hold | maintain with attitude | positions other than these. You can also do it.

  The dispenser 21 has both a function of supplying the adhesive stored therein and a function of sucking in the direction opposite to the supply, and is controlled by the computer 13 as described above. The supply and suction of the adhesive are performed through the hose 20, and the adhesive is discharged from the nozzle 19 by the supply, and the surplus adhesive is sucked into the nozzle 19 from the tip of the nozzle 19 by the suction. The supply and suction of the adhesive are triggered by the detection and non-detection of the to-be-grafted body by the distance sensor 25. That is, when the nozzle 19 approaches the planted body 111, that is, when the nozzle 19 falls below a predetermined distance (the working distance of the distance sensor 25), the discharge of the adhesive is started. When the distance is exceeded, the discharge of the adhesive is stopped and the adhesive is sucked. Adhesive suction is mainly for preventing a drop in surplus adhesive when discharging is stopped and pattern thickening due to application of surplus adhesive when starting discharging. That is, the nozzle 19 is sucked to remove excess adhesive that causes dropping and pattern thickening. The dispenser 21 is not limited in its supply method as long as it is capable of supplying a fixed amount of adhesive as a fluid. An adhesive supply device using an inkjet method or a spray method is also included in the dispenser referred to in this specification.

(Composition of the flocked part)
This will be described with reference to FIG. The electrostatic flocking unit 7 includes a flocking gun 31 for flocking and a supply unit 41 for supplying flocks to the flocking gun 31. The flocking gun 31 has an external structure composed of a support cylinder 33 extending in the horizontal direction and a prismatic recovery duct 39 attached to the lower part of the support cylinder 33. The support cylinder 33 has one end side (left side in FIG. 2) opened and the other end side (right side in FIG. 2) closed with a closing plate 33a. A flock supply port 33 b is opened on the upper surface of the support cylinder 33, and a communication hole for communicating with the inside of the recovery duct 39 is opened on the lower surface. A radiation hole 33h is opened substantially at the center of the closing plate 33a, and an electrode 35 connected to a power source 37 is disposed near the closing plate 33a in the support cylinder 33. The power source 37 is configured to be controllable by the computer 13. The inner diameter of the radiation hole 33h was 5 mm. The reason why the floc F is blown out through the radiation hole 33h is to enable spot radiation to plant the floc F only at a necessary portion. Further, the reason why the inner diameter was set to 5 mm is that it is considered to be suitable for spot-like radiation, although it depends on the distance to the planted body 111. The inner diameter can be appropriately adjusted according to the shape of the pattern, the shape of the planted hair, and the like.

  The supply unit 41 includes a drop pipe 41b inserted into the flock supply port 33b and an inverted conical storage unit 41a attached to the upper part of the drop pipe as main members. The entire supply unit 41 has a funnel shape, and is configured such that the floc F stored in the storage unit 41 a falls in the drop pipe 41 b and falls into the support cylinder 33 through the flock supply port 33 b. It is. The mesh 41m is arranged in the reservoir 41a so that the floc F does not easily fall, and the floc F is supplied onto the mesh 41m. The reservoir 41a is configured such that vibration is applied by the eccentric motor 43, and the floc F falls through the mesh 41m by this vibration. The electrode 35 is formed in a substantially columnar shape, and an end surface facing the closing plate 33a is an upward inclined surface 35a that is inclined downward toward the closing plate 33a. The inclined surface 35a is arranged directly below the flock supply port 33b, so that the flock F falling from above can be easily deflected in the direction of the radiation hole 33h. The floc F that has fallen is deflected as described above and blown from the radiation hole 33h, but has been deflected but has not been blown by colliding with the closing plate 33a, or falls without being deflected. The floc F that has not been blown out is collected in the collection duct 39 through the communication hole. Since the radiation direction of the radiation hole 33h in this embodiment is substantially horizontal, the hair transplantation to the hair transplant body 111 after the application of the adhesive is performed while being held in the vertical direction as shown in FIG. The flocking gun 31 is configured to be movable by the biaxial table 46, and the flock F is configured to be flocked to a predetermined portion of the flocked body 111 by this movement. That is, the biaxial table 46 is a drive unit (not shown) for moving the X-axis arm 46x, the Y-axis arm 46y, and the X-axis arm 46x and the Y-axis arm 46y in the XY direction (vertical plane direction). The flocking gun 31 is fixed to the upper surface so as to move integrally with the X-axis arm 46x. The biaxial arm 46 is controlled through the computer 13. In addition, in this embodiment, although the to-be-grafted body 111 is fixed and the flocking gun 31 is relatively moved with respect to this to-be-grafted body 111, the flocking gun 31 is contrary to this. It may be configured that the hair transplant body 111 is moved relative to the hair transplantation gun 31 in advance. Furthermore, both the to-be-grafted body 111 and the flocking gun 31 can be configured to be movable so that the relative position between them can be changed.

  As described above, the power source 37 is connected to the electrode 35. This is because a high voltage is applied to the electrode 35 to charge the floc. The reason why the floc is charged is that the flock is attracted to the flocked body by electrostatic force by electrically grounding the flocked body. The attracted flock adheres to the flocked pattern 111a. Electrostatic flocking is performed by these series of flows. As described above, in order to perform electrostatic flocking, it is necessary to apply a high voltage to the electrode. However, if a high voltage is continuously applied, there is a possibility that a floc aggregation phenomenon or a bridge phenomenon may occur. The floc aggregation phenomenon refers to a phenomenon in which flocs are aggregated, that is, solidified by flapping together. The flock bridging phenomenon refers to a phenomenon in which flocks are connected and bridged between the electrode and the hair transplanted body, that is, the high potential portion and the ground potential portion. When the bridging phenomenon occurs, there may be a case where the electrode and the to-be-grafted body are electrically short-circuited. Needless to say, the agglomeration phenomenon and bridging phenomenon may interfere with smooth flocking and disrupt the desired flocking pattern. Therefore, in this embodiment, the computer 13 is configured to be able to perform intermittent control of the power source 37. That is, application of a short time is interrupted at a predetermined cycle or timing during hair transplantation. This is to interrupt the charging of the flocs until the application is restarted due to the interruption of the application, thereby effectively preventing aggregation and bridging that would have occurred if the application was continued. In the present embodiment, intermittent control is performed at a cycle in which application of 40 kV voltage is applied for 5 seconds and then application is stopped for 1 second. As a result, floc aggregation and bridging could be effectively prevented without adversely affecting the flocking finish. Therefore, the intermittent control of the power source 37 contributes to the formation of a flocking pattern that is rich in diversity from the standpoint of flocking. Note that the above period may vary depending on conditions such as applied voltage level, floc material and size, distance between electrode and grafted body, etc. It is better to set the length (interval) that seems to be optimal in consideration of

(Procedure for using the hair transplanting device)
Reference is made to FIGS. First, an adhesive is selected. As the adhesive G used in this embodiment, an acrylic emulsion adhesive widely used for flocking processing was used. The viscosity of the acrylic emulsion adhesive can be increased by adding ammonia. Viscosity is deeply related mainly to the surface properties of the planted hair. In this embodiment, sheet-like paper or resin is used as the planted body, but when the existing acrylic emulsion adhesive is applied as it is, the line formed by application spreads (though the adhesive flows) into a thick line. It is had. At this time, the viscosity of the acrylic emulsion adhesive was 2,000 cps. Therefore, the viscosity was adjusted by adding 0.5% of 29% ammonia water to the acrylic emulsion adhesive. When this viscosity-adjusted acrylic emulsion adhesive is applied using the nozzle 19 having an inner diameter of 1.4 mm in the flow path 19c, it is possible to apply (draw) about 1 mm in thickness to the surface of the hair transplant body 111. became. Needless to say, the selection of the adhesive and its viscosity must be determined in consideration of the properties of the planted body, the wire diameter of the desired coating pattern, and the like.

  First, the image pattern 101 a is read from the medium 101 using the scanner 11, and the read image data is processed by the computer 13. Next, adhesive application based on the read image data is performed on the hair transplant body 111 placed on the upper surface of the table body 23a. The adhesive application starts when the computer 13 transmits a command based on the image data to the adhesive application unit 5. The adhesive application unit 5 that has received the command moves the X-axis movable unit 23b, the Y-axis movable unit 23c, and the Z-axis movable unit 23d, and moves the nozzle 19 to a position necessary for forming the flocking pattern 111a. When the nozzle 19 arrives at a predetermined position, the Z-axis movable part 23d operates to lower the nozzle 19. Here, when the distance sensor 25 detects that the distance to the hair transplant body 111 has reached a predetermined distance, a hair transplant body detection signal is output, and the computer 13 that has received this hair transplant body detection signal issues a command to the dispenser 21. Adhesive discharge through the feed nozzle 19 is started. Adhesive application is performed by this start. The computer 13 sends a drive command to the X-axis movable unit 23b and / or the Y-axis movable unit 23c together with the adhesive discharge command. The drive command is issued within the range and limit necessary for forming the flocking pattern 111a.

  When the application is temporarily interrupted in order to draw a pattern discontinuity on the design in the middle of the formation of the hair transplantation pattern 111a, or when the adhesive application itself is terminated, the triaxial table 23 received the command from the computer 13 Moves the Z-axis movable part 23d to raise the nozzle 19. When the nozzle 19 is raised, the distance sensor 25 detects that the hair transplant body 111 has moved out of a predetermined distance (effective detection distance). Upon receiving this detection signal (or blocking of the received detection signal), the computer 13 sends a command to the dispenser 21 to instruct the suction of excess adhesive. Receiving the suction instruction, the dispenser 21 sucks into the nozzle 19 excess adhesive that is about to fall from the tip 19 b of the nozzle 19. Thereby, pattern thickening due to the application of excess adhesive can be effectively prevented. The code | symbol 111a shown in FIG. 1 has shown the flocking pattern drawn with the adhesive agent apply | coated to the to-be-grafted body 111. FIG.

  The to-be-grafted body 111 on which the flocking pattern 111a is formed performs electrostatic flocking by the electrostatic flocking unit 7 while maintaining this vertically. For example, the flocking gun 31 of the electrostatic flocking unit 7 is scanned and moved along the flocking pattern 111a in the XY axis direction while applying a voltage of about 40 kV to the electrode 35. The movement of the flocking gun 31 is performed by a biaxial table 46 controlled by the computer 13. A series of flocking operations are completed when the entire flocking pattern 111a has been flocked. As can be understood from the above description, since the flocking pattern 111a is created based on the image pattern 101a read (input) from the scanner 11, even if it is not only a simple design but also a complicated design, Even if it does not make the material used for screen printing every time, it can apply the adhesive agent of the pattern requested | required, and can perform electrostatic flocking. Therefore, it goes without saying that it is suitable for mass production, and it is possible to perform a variety of flocking even for products that are not familiar with mass production, such as ones that are highly artistic and that produce a small number.

(Modification of this embodiment)
This will be described with reference to FIG. The modification of the present embodiment (hereinafter referred to as “this modification” as appropriate) differs from the present embodiment described above mainly in the number of hair transplantation guns and the control method thereof, and the other parts are essential. There is no difference. Therefore, in order to avoid redundant description, only the parts that are different between the present modification and the present embodiment will be described below, and common parts will be cited as necessary. In addition, about the site | part which is common in both, the same code | symbol as the code | symbol shown in FIG. 2 may be used in FIG.

  The biaxial table 59 related to the electrostatic flocking unit 57 according to this modification is configured to include an X-axis arm 59x, a Y-axis arm 59y, and a driving unit (not shown), 3 is omitted), and is relatively movable in the XY axis direction. Three groups of flocking guns 31R, 31B and 31Y are fixed on the upper surface of the X-axis arm 59x, and the three groups move together with the X-axis arm 59x. The flocking guns 31R, 31B and 31Y have the same structure as the flocking gun 31 described above, the flocking gun 31R is for red flock radiation, and the flocking gun 31B is a blue flock. The flocking gun 31Y is for yellow floc radiation. All the flocking guns for radiation of each color are set to be individually controllable by the computer 13. That is, when it is desired to plant red flock, the flocking gun 31R is moved to a desired location and then driven. When blue flocking is desired, the flocking gun 31B is also driven. By driving the flocking gun 31Y in the same manner, it is possible to plant the three-color flocks on the same or separate flocked bodies outside the figure. Although it is realistic to drive the three hair transplantation guns individually, if possible, a plurality of hair transplantation guns (for example, the hair transplantation gun 31R and the hair transplantation gun 31B) may be driven simultaneously. The color of the flock does not have to be limited to the above three colors, and may be selected as appropriate according to preference and application. Also, two colors may be used instead of three colors, or four or more colors may be used. Multi-colored flocking greatly contributes to the creation of a more diverse flocking pattern than single-colored flocking on the same flocked body. As described above, a plurality of flocking guns are used, and each flocking gun is radiated with a flock of a different color, or alternatively, a different type (eg, material, size) of flock. It can be said that it is preferable to improve the diversity.
