Description

  The present invention relates to a filling nozzle for filling oily cosmetics that require melt filling such as lipstick.

  Oily cosmetics such as lipsticks are prepared by solidifying semi-solid oil or liquid oil in which powder is dispersed with a solidifying agent. When filling an oily cosmetic into a container, the filling nozzle is inserted into the container, and the filling nozzle is pulled up while discharging the melted oily cosmetic from the filling nozzle. When the oily cosmetic is filled in the container, it is cooled by the air or the container and solidifies immediately.

  Here, heating the filling nozzle is conventionally performed so that the oily cosmetic does not solidify in the filling nozzle. Conventional heating methods include the following. First, a pair of electric heaters are arranged at positions 5 to 10 cm away from the filling nozzle group on both sides of the filling nozzle group composed of a plurality of filling nozzles arranged at predetermined intervals. There is a method of heating the filling nozzle group with radiant heat. Alternatively, there is also a method in which hot air is generated with compressed air using this heater as a heat source and blown to a filling nozzle group. These are methods of heating the filling nozzle indirectly from a heat source remote from the filling nozzle.

  Patent Document 1 provides a double-structured filling nozzle comprising an inner cylinder through which filling cosmetics pass and an outer cylinder arranged on the outer periphery of the inner cylinder. By providing a medium discharge hole and circulating the temperature adjustment medium in the space between the inner cylinder and the outer cylinder, the filling nozzle is directly heated, and the temperature of the cosmetic passing through the inner cylinder is set to the set temperature. Techniques to maintain are described.

Japanese Patent Laid-Open No. 11-227718

  However, these conventional heating methods have the following problems.

  The temperature of the oily cosmetic in the filling nozzle affects the finished surface of the solidified oily cosmetic after filling. In particular, in the case of lipsticks containing glittering powder such as so-called pearl pigments, if the temperature of the filling nozzle, especially the temperature at the tip of the filling nozzle, is not properly controlled, unevenness of the pearl pigment will occur on the finished surface, resulting in commercial value. It becomes something without. Specifically, the lipstick slightly exposed from the discharge outlet at the tip of the filling nozzle due to surface tension and gravity is solidified faster when the temperature at the tip of the filling nozzle is lowered. Therefore, it is discharged from the nozzle in a so-called lumpy state in the container to be filled next, and as a result, it does not become a beautiful finished surface and becomes a defective product. Therefore, the filling nozzle is required to be constantly maintained at a constant temperature over time during operation. When a plurality of containers are filled simultaneously with a group of filling nozzles composed of a plurality of filling nozzles, the same is required for all the filling nozzles.

  However, in the case of a method in which the filling nozzle is heated indirectly from a heat source away from the filling nozzle, it is easily affected by changes in the surrounding environment such as air conditioning conditions around the filling nozzle, and the filling nozzle is maintained at a constant temperature over time. There was a problem that it was difficult to do. As a result, the finished surface after filling varied, and a product with unevenness on the finished surface had to be disposed of as a defective product. In addition, in this method, the temperature of the filling nozzles at both ends of the filling nozzle group is likely to decrease, but the temperature of the filling nozzles at the center is relatively stable. It was a problem. Furthermore, in the case of this method, since large electric heaters are disposed on both sides of the filling nozzle group, there is a problem that the apparatus becomes large and, for example, it is difficult to adjust the filling nozzle.

  In addition, as in Patent Document 1, the method of heating each filling nozzle with a temperature control medium is a method of directly heating the filling nozzle. Therefore, although the temperature of the filling nozzle is easy to maintain over time, It is necessary to provide a supply / discharge mechanism for the adjustment medium, the apparatus is large, and the internal structure of the filling nozzle is complicated. In addition, the temperature adjustment medium may be deteriorated with time, and when the temperature change medium is deteriorated, the temperature adjustment medium may be clogged in the space between the inner cylinder and the outer cylinder due to the generation of foreign matter or a change in viscosity. Therefore, a technique for replacing the method for circulating the temperature control medium has been demanded.

  Accordingly, an object of the present invention is to provide a filling nozzle for oily cosmetics that can easily maintain the filling nozzle at a constant temperature over time with a simple apparatus configuration.

In order to achieve the above object, the gist of the present invention is as follows.
An oily cosmetic filling nozzle according to the present invention defines an internal space through which oiling cosmetic for filling passes, a cylindrical nozzle having a discharge port for the oily cosmetic at the tip, and an outer peripheral surface of the cylindrical nozzle.

  In this invention, it is preferable that the said control part controls the electric power supply to the said electric heater so that the temperature detected by the said temperature sensor may be settled in a predetermined range, or it becomes a fixed value.

  The filling nozzle of the present invention preferably includes a plurality of the cylindrical nozzles, and the control unit is capable of independently controlling power supply to the electric heaters provided in the plurality of cylindrical nozzles. .

  Further, the filling nozzle of the present invention has an outer cylinder arranged on the outer periphery of the cylindrical nozzle, and the electric heater and the temperature sensor are arranged between the cylindrical nozzle and the outer cylinder. Is preferred.

  In the present invention, the electric heater is preferably a planar heater formed by sealing a heating wire with a resin film. In this case, the electric heater is preferably arranged such that the heating wire is more densely arranged closer to the discharge port, and the temperature sensor is sealed with the resin film together with the heating wire.

The hopper 62 is provided with a heater, and the internal cosmetic L is melted at about 90 ° C. and kept warm. The hopper 62 and the cylinder block 64 are connected to the connection block 60. Further, the connection block 60 is provided with a flow path (not shown) for receiving the cosmetic L from the hopper 62 inside. By driving the servo motor 68 and pushing the piston rod 66 into the cylinder block 64, the melted cosmetic L is sent from the flow path in the connection block to the nozzle portions 10A to 10E.

Then, the oily cosmetic is filled in the container 1, cooled by air or the container 1, and immediately solidified. The container 1 filled with the oily cosmetic is transported from directly below the nozzle portions 10A to 10E to the next step for product completion. By repeating the above operation, a large amount of containers can be filled with the oily cosmetic.

  With reference to FIGS. 3-6, 10 A of nozzle parts used with the filling apparatus 200 of FIG. 1 are demonstrated.

  The nozzle portion 10 </ b> A is a double-structured nozzle having a cylindrical nozzle 12 and an outer cylinder 32 disposed on the outer periphery of the cylindrical nozzle, and the cylindrical nozzle 12 and the outer cylinder 32 are inserted into the nozzle head 34. Yes. As shown in FIGS. 1 and 2, the base block 40 is provided with a male screw 36 which is cylindrical and hollow inside. The nozzle head 34 of the nozzle portion is inserted into the hollow of the male screw 36, and the lock nozzle 38, which is a female screw, is further closed, whereby the filling nozzle 10A is fixed to the base block 40.

  The cylindrical nozzle 12 is not particularly limited as long as it is a material having good thermal conductivity. For example, the cylindrical nozzle 12 is made of a material such as stainless steel, a copper alloy, an aluminum alloy, or a titanium alloy, and an internal space 14 through which the oily cosmetic for filling passes. And has an oil-based cosmetic discharge port 16 at the tip. The dimensions of the cylindrical nozzle 12 are not particularly limited, but when a lipstick is filled into a general rod-shaped container 1, it is an elongated shape having a length of about 30 to 100 mm, an inner diameter of about 3 to 5 mm, and an outer diameter of about 4 to 7 mm. And Heated and melted oily cosmetic is introduced into the internal space 14 from the end of the cylindrical nozzle 12 opposite to the discharge port 16.

  Moreover, the outer cylinder 32 consists of materials, such as stainless steel and heat resistant resin, for example. Although the dimension of the outer cylinder 32 is not specifically limited, when filling a stick-shaped container 1 with a general lipstick, it is set as about 5-8 mm in outer diameter. Furthermore, the inner diameter is made larger by about 0.5 mm than the outer diameter of the cylindrical nozzle 12, and a clearance between the cylindrical nozzle 12 and the outer cylinder 32 is secured by about 0.5 mm. The inner diameter of the container for filling the lipstick is not particularly limited, but is generally 9 to 12 mm. Therefore, the outer diameter of the filling nozzle 10A is set as described above.

  As shown in FIG. 3, in the nozzle portion 10A, a planar heater 20 as an electric heater is arranged between the cylindrical nozzle 12 and the outer cylinder 32, specifically, on the outer peripheral surface 18 of the cylindrical nozzle. Has been established. As shown in FIG. 4, the planar heater 20 is formed by sealing a heating wire 22 such as a nichrome wire or a stainless steel foil with a resin film 24 such as polyimide or phenol resin. The planar heater 20 shown in FIG. 4 is wound around the outer peripheral surface 18 of the cylindrical nozzle 12, and the outer cylinder 32 is fitted into the cylindrical nozzle 12 from above. The planar heater 20 may be attached to the outer peripheral surface 18 of the cylindrical nozzle 12 with an adhesive. As shown in FIG. 4, both ends of the heating wire 22 are soldered and connected to the electric wire 23, and the two electric wires 23 come out of the resin film 24 with a pair of tabs 25 that are part of the resin film 24. The heating wire 22 generates heat by the power supplied via the electric wire 23 and heats the cylindrical nozzle 12. Moreover, as shown in FIG. 4, the heating wire 22 is arrange | positioned densely, so that the planar heater 20 goes below. When the planar heater 20 is disposed on the outer peripheral surface 18 of the cylindrical nozzle 12, the posture is such that the lower side where the heating wires 22 are densely disposed is close to the discharge port 16. Is preferred. The thickness of the planar heater 20 is about 0.08 to 0.15 mm.

  As shown in FIG. 3, a temperature sensor 26 is disposed in the nozzle portion 10 </ b> A between the cylindrical nozzle 12 and the outer cylinder 32, specifically, on the outer peripheral surface 18 of the cylindrical nozzle. The temperature sensor 26 is provided in a discharge port side end region on the outer peripheral surface 18 of the cylindrical nozzle 12 and detects the temperature of the region constantly or intermittently. As the temperature sensor 26, as shown in FIG. 5, an arbitrary sensor that can be sealed with a resin film 30 such as polyimide or phenol resin to have a thickness of about 0.05 to 0.15 mm is selected. The output of the temperature sensor 26 is transmitted to a control unit described later through two wires 28. When the temperature detection by the temperature sensor 26 is performed intermittently, it is preferable to set the interval once every 60 milliseconds, for example.

  As shown in FIG. 3B, it is preferable that the outer peripheral surface 18 of the cylindrical nozzle 12 is provided with a planar heater 20 other than the portion where the temperature sensor 26 is provided on the entire circumference. This is because the entire circumference of the cylindrical nozzle 12 can be heated uniformly. Or you may provide the planar heater 20 in the perimeter of the outer peripheral surface 18 so that the temperature sensor 26 may be covered. As shown in FIG. 6, the outer cylinder 32 is provided with an opening in the vicinity of the nozzle head 34, and a pair of tabs 25 of the planar heater 20 wound around the cylindrical nozzle 12 are provided in the opening. The electric wire 23 is supplied with electric power for generating heat from the heating wire 22. Further, the two wires 28 of the temperature sensor are also drawn from the opening and connected to the control unit.

  The nozzle portions 10B to 10E have the same structure as the nozzle portion 10A. That is, the planar heater 20 and the temperature sensor 26 are also provided in the nozzle portions 10B to 10E.

  Next, control of the electric heater in the nozzle portions 10A to 10E will be described with reference to FIG. FIG. 7 is an electrical block diagram of the filling nozzle 100. The planar heaters 20A to 20E and the temperature sensors 26A to 26E are connected to the control units 50A to 50E, respectively. The control units 50A to 50E are connected to a 100 V AC power source via AC / DC converters 52A to 52E, respectively. In the AC / DC converters 52A to 52E, AC100V is converted to DC12V. In addition, you may provide the monitor (not shown) which each displays the temperature which temperature sensor 26A-26E detected in real time.

The target temperatures T _set of the temperature sensors 26A to 26E are set in the control units 50A to 50E, respectively. The target temperature is an appropriate temperature at which the oily cosmetic can be filled so that there is no unevenness in the finished surface. In the case of a general lipstick, for example, an oily cosmetic that is fluid at about 90 ° C. is introduced into the internal space 14 of the cylindrical nozzle 12. Therefore, the target temperature of the temperature sensors 26A to 26E, that is, the temperature in the vicinity of the discharge port of the cylindrical nozzle 12 is preferably about 90 to 95 ° C.

  And control part 50A-50E supplies electric power to planar heater 20A-20E based on the temperature detected by temperature sensors 26A-26E. Hereinafter, the filling nozzle 10A will be specifically described as an example.

First, the temperature T detected by the temperature sensor 26A is transmitted to the control unit 50A. The control unit 50A compares the detected temperature T with the target temperature T _set . When the detected temperature T falls below the target temperature T _set , the control unit 50A supplies the electric power output from the AC / DC converter 52A to the planar heater 20A and energizes the planar heater 20A. As a result, the planar heater 20A generates heat. When the planar heater 20A generates heat, the temperature near the discharge port of the cylindrical nozzle 12 changes, and as a result, the temperature T detected by the temperature sensor 26A changes.

On the other hand, when the detected temperature T is equal to or higher than the target temperature T _set , the control unit 50A controls the electric power output from the AC / DC converter 52A to be cut off and not supplied to the planar heater 20A.

  And the temperature detection by the temperature sensor 26 is intermittently performed, and the control based on the detected temperature T is performed each time.

By such On-Off control, the control unit 50A controls power supply to the planar heater 20A so that the temperature T detected by the temperature sensor 26A becomes a constant value _Tset . As a result, when the detection temperature T is started from room temperature, the detection temperature T reaches the target temperature T _set of 90 to 95 ° C. in about several tens of seconds, and then detected within the range of ± 1 ° C. of the target temperature. The temperature T can be maintained. According to the monitor that displays the temperature detected by the temperature sensor 26A in real time, it can be confirmed whether the temperature management of the cylindrical nozzle 12 is appropriately performed. When the detected temperature T reaches the target temperature T _set , the above-described filling operation may be started. In addition, this On-Off control is performed every 60 milliseconds, for example, so that the temperature of the nozzle portion 10A can be managed to be substantially constant.

  The same control can be performed for the nozzle portions 10B to 10E. That is, in this embodiment, control part 50A-50E can control independently the electric power supply to the planar heaters 20A-20E provided in the five nozzle parts 10A-10E, respectively.

  According to the filling nozzle 100 according to the present embodiment described above, the following effects can be obtained.

  First, in this embodiment, the planar heater 20 that directly heats the filling nozzle is used, and the power supply to the planar heater 20 is controlled according to the output of the temperature sensor 26. Therefore, it is possible to suppress fluctuations in the temperature of the filling nozzle with time as much as possible. As a result, the quality of the finished surface after filling can be kept constant. That is, unevenness hardly occurs on the finished surface after filling. In addition, since a large heater, a temperature control medium circulation device, and the like are unnecessary, a simple device configuration can be achieved.

Furthermore, since an electrothermal heater is used, it is preferable in that the response speed is high. As described above, immediately after the heater is turned on, the detected temperature T can reach the target temperature T _set in about 10 seconds, and for example, even when the target temperature T _set is changed, 10 seconds. Within the range, the detected temperature T can be followed.

  According to the above-described on-off control so that the detected temperature T becomes a constant value, the filling surface can be filled evenly by keeping the temperature of the filling nozzle constant over time.

  In this embodiment, the power supply to the respective planar heaters of the plurality of filling nozzles can be controlled independently, so that the target temperatures of all the filling nozzles can be set to be the same. Therefore, temperature variation among a plurality of filling nozzles can be suppressed. Moreover, the target temperature of each filling nozzle can also be varied. This is effective when performing so-called multicolor (various) filling. That is, when a plurality of types of oily cosmetics having different appropriate filling temperatures are filled in a plurality of filling nozzles, if different target temperatures are set for each filling nozzle, appropriate filling can be performed in all filling nozzles. .

  In the present embodiment, the outer cylinder 32 is provided, and the planar heater 20 and the temperature sensor 26 are disposed between the cylindrical nozzle 12 and the outer cylinder 32. Therefore, it is possible to avoid the oil-based cosmetic material from adhering to the planar heater 20 and the temperature sensor 26 and being seized by the outer cylinder 32. Moreover, since the planar heater 20 can be urged toward the outer peripheral surface 18 of the cylindrical nozzle 12 by the outer cylinder 32, it is also preferable in that an adhesive or the like is not required. Furthermore, heat from the planar heater 20 can be transmitted to the cylindrical nozzle 12 without escaping, and the temperature detection by the temperature sensor 26 is not affected by outside air, so that the accuracy is high.

  In this embodiment, since the very thin planar heater 20 of about 0.08 to 0.15 mm is used, the diameter of the filling nozzle is not increased.

  In the present embodiment, in the planar heater 20, the heating wires 22 are densely arranged closer to the discharge port 16. Therefore, it is possible to reliably heat the vicinity of the discharge port where the temperature tends to decrease.

Hereinafter, modifications of the filling nozzle for oily cosmetics according to the present invention will be described. In the above embodiment, the target temperature T _set is a constant value, but the present invention is not limited to this, and the target temperature may be a predetermined range. For example, the range of 93 to 94 ° C. is set as the target temperature, and the control unit 50 controls the power supply to the planar heater 20 so that the detected temperature T is within the range.

  In the above embodiment, the planar heater 20 is provided in the entire region below the nozzle head 34 on the outer peripheral surface 18 of the cylindrical nozzle 12, but the present invention is not limited to this, and the outer peripheral surface of the cylindrical nozzle 12. 18 may be provided at least in the discharge port side end region. As described above, in the cylindrical nozzle 12, a decrease in temperature particularly in the vicinity of the discharge port becomes a problem. Therefore, if the area is provided in the region, the oily cosmetic does not solidify in the filling nozzle, and after filling, This is because it is possible to obtain an effect that unevenness hardly occurs on the finished surface.

  Although the example of five filling nozzles was shown in the said embodiment, it is not restricted to this, A plurality or one may be sufficient. This is because even with a single filling nozzle, it is possible to obtain an effect that fluctuation of the temperature of the filling nozzle with time can be suppressed as much as possible.

  In the above embodiment, the planar heater 20 is used. However, the present invention is not limited to this, and any other electric heater may be used as long as it does not hinder insertion of the filling nozzle into the container 1 to be filled. be able to. For example, a heating wire may be wound around the outer peripheral surface of the cylindrical nozzle in a spiral shape to form a coiled heater.

  FIG. 8 shows a modification of the tip of the filling nozzle. Thus, it is preferable that the filling nozzle has a configuration in which the cylindrical nozzle 12 protrudes from the outer cylinder 32 at the tip. Specifically, the distance D between the tip of the cylindrical nozzle 12 and the tip of the outer cylinder 32 can be about 1 mm. As described above, cosmetic material is slightly exposed from the discharge port 16 of the filling nozzle 12 due to surface tension and gravity, and this may cause an adverse effect on the finished surface. As shown in FIG. 3, when the tip of the cylindrical nozzle 12 and the tip of the outer cylinder 32 are aligned, the cosmetic exposed from the discharge port 16 may reach the outer cylinder 32. On the other hand, in FIG. 8, the cosmetic exposed from the discharge port 16 does not reach the outer cylinder 32, and the adverse effect on the finished surface can be reduced.

  In addition, as shown in FIG. 8, it is preferable that the tip of the outer cylinder 32 has a shape narrowed down to the outer diameter of the cylindrical nozzle 12. The centering property of the outer cylinder 32 is improved, and the cosmetic material from the discharge port 16 adheres to a planar heater and a temperature sensor (not shown in FIG. 8) disposed between the cylindrical nozzle 12 and the outer cylinder 32. , Can prevent seizure.

  In the above embodiment, the temperature sensor 26 is sealed with the resin film 30 separately from the planar heater 20, but the temperature sensor 26 and the heating wire 22 are sealed with the resin film so that the planar heater and the temperature sensor are integrated. It is also possible to use different modules.

  The “oil-based cosmetic” in the present invention means a cosmetic having an oil-based component as a continuous phase and solidified by cooling after melt-filling. The oily cosmetic may be a non-aqueous type that does not contain an aqueous phase, or a water-in-oil type in which the aqueous phase is dispersed or emulsified in the oil phase. For example, the oily cosmetic contains 3% or more of a solidifying agent. The present invention is suitable for manufacturing a stick-shaped cosmetic material such as a lipstick, but the shape of the container 1 is not limited to a stick shape, and may be a dish shape, a jar type, a tube, a bottle, or the like.

  According to the present invention, it is possible to provide a filling nozzle for oily cosmetics that can easily maintain the filling nozzle at a constant temperature over time with a simple apparatus configuration.
