  By the way, although it depends on the prescription, the molded product solidified by the preliminary press often has a characteristic that it is brittle and easily collapsed because it is loosely pressurized. Therefore, it is necessary to carefully transfer the dressing plate so that the punched product does not collapse. In fact, this work is often performed manually, and the operator picks up one by one from the tray in which a large number of molds are stored, and carefully stores the molds in the vanity plate. Go. In order to improve productivity, it is preferable to automate this operation. However, it is not always easy to handle individual punched articles accommodated in arbitrary positions inside a tray or the like without breaking them. Is a factor that hinders automation.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to automate a production line for multicolor cosmetics by enabling transfer to a cosmetic dish without breaking the mold.

  In order to solve this problem, the present invention provides a method for producing a multicolor cosmetic having the following first to third steps. In the first step, information necessary for operating the transfer machine that holds and moves the object is registered. This information includes the movement start point according to the position of the first filling space and the position of the second filling space on the production line, the first storage position and the second position on the vanity set set at a predetermined position. The movement end point according to the accommodation position is included. In the second step, the first casting is generated by the powder cosmetic molding in the first filling space, and the first molding is performed by the powder cosmetic molding in the second filling space. A second punching object having a color tone different from that of the object is generated. In the third step, the transfer machine is operated according to an operation condition that the object is held at the movement start point, the object is moved from the movement start point to the movement end point, and the object is released at the movement end point. As a result, the first casting object existing at the position of the first filling space is moved to the first accommodation position. At the same time, the second casting object existing at the position of the second filling space is moved to the second accommodation position.

  Here, in the third step of the present invention, the transfer machine has the first casting object existing at the position of the first filling space, and the second placed side by side with the first filling space. You may hold | maintain and move the 2nd casting object which exists in the position of a filling space simultaneously. Further, in the third step, the transfer machine changes the position or orientation of the first casting object and the second casting object to a state different from the movement start point by a movable mechanism provided in itself. You may let them. As a result, the position or orientation that matches the arrangement in the decorative dish can be achieved. In the third step, the transfer machine preferably holds the first casting object and the second casting object by suction.

  In the present invention, the second step includes filling a powder cosmetic into each of the first filling space and the second filling space formed by combining a pair of molds; A step of pressing the powder cosmetic filled in each of the filling space and the second filling space and displacing the other mold with respect to one mold are formed in the first filling space. You may have the step which exposes the 1st casting object and the 2nd casting object formed in the 2nd filling space to the state which a transfer machine can hold | maintain.

  According to the present invention, it is possible to improve productivity by automating the operation of transferring the molding object into the decorative dish using the transfer machine. In a state in which a large number of castings are accommodated in a tray or the like, not only the accommodation positions of the individual castings can be specified uniquely, but the castings are liable to be destroyed when they are taken out. This problem can be solved by fixing all the castings at the same position, that is, a specific position of the filling space on the production line. This is because the positions and orientations of all the punched objects on the production line are uniform at this position. If the arrangement state of the castings to be transferred is made uniform, it is not necessary to apply an excessive load to the castings at the time of transfer, so that the collapse of the castings can be suppressed.

  FIG. 1 is a schematic view of an automatic production line for multicolor cosmetics according to the present embodiment. The work target of this automatic production line 1 is, for example, powder solid cosmetics such as foundations, face powders, and eye shadows. A plurality of solid cosmetics having different colors are obtained by molding and solidifying the cosmetic powder. It is formed by the subject. This solid cosmetic may be either a dry cosmetic or a wet cosmetic. The dry cosmetic is obtained by molding and solidifying a cosmetic powder. In addition, the wet cosmetics are solidified by absorbing and drying volatile components in the slurry (the cosmetic fluid). As the slurry, a mixture of a cosmetic base material and a volatile solvent such as ethanol, water, liquid paraffin, isoparaffin, and isopropyl alcohol is used. Wet cosmetics have a characteristic that a moist feeling of use can be obtained due to the sparse particle density compared to dry cosmetics. Further, in this specification, the term “different color tone” is used in a sense that it is sufficient if the user can visually recognize the difference between the two. Therefore, not only differences in brightness, saturation, and hue, but also the same color, but those with different textures, such as those with pearls added and those that are not, fall within the category of “different colors” here. included. In the present embodiment, two-color stripes are exemplified, but more than three color stripes may be used by using more colors of solid cosmetics, and further, a curved complex color pattern may be used. .

  The automatic production line 1 includes a turntable 2, a conveyance path 3, and a transfer machine 4 installed between them. Various manufacturing apparatuses 5 to 7 described later are installed at predetermined positions A, B, and E on the transport path. The turntable 2 positioned upstream of the transfer machine 4 is rotatably provided, and a plurality of recessed portions that are recessed in a concave shape are formed along the circumferential direction at predetermined intervals. Moreover, the metal mold | die 8 is inserted in each depression part so that attachment or detachment is possible. The upper surface of the mold 8 fitted in the turntable 2 is flush with the upper surface of the turntable 2. By repeatedly rotating and stopping the turntable 2, the mold 8 moves in the order of the transport positions A, B, and C.

  FIG. 2 is a cross-sectional view of the mold 8. The mold 8 is configured by combining a pair of molds 8a and 8b, and a lower mold 8b is assembled to the upper mold 8a so as to be movable up and down. Specifically, the upper mold 8a has a shape corresponding to the depressed portion of the turntable 2, and its central portion penetrates vertically. A step 8c is provided on the inner wall of the penetrating portion. On the other hand, the lower mold 8b is fitted in a penetrating portion of the upper mold 8a so as to be movable up and down. When the lower mold 8b is lowered, the lower mold 8b is positioned below the top surface of the upper mold 8a, thereby forming two filling spaces 8d and 8e. On the other hand, in a state where the lower mold 8b is raised, that is, in a state where the convex portion 8f protruding laterally from the outer periphery of the lower mold 8b is in contact with the step 8c of the upper mold 8a, the filling spaces 8d and 8e are filled. And the top surfaces of the upper and lower molds 8a and 8b are flush with each other. The shape and number of the filling spaces 8d and 8e are appropriately determined according to the color pattern of the multicolor cosmetic to be manufactured. For example, in the case of forming a linear two-color stripe, it is sufficient to mold two rectangular parallelepiped moldings. In this case, each opening shape of the two filling spaces 8d and 8e is formed in a rectangular shape.

  Referring to FIG. 1 again, the transfer machine 4 is mainly composed of a plurality of holding units 4a, a moving arm 4b, a driving unit 4c, and a control unit 4d, and according to preset operation conditions. Operate. Each holding part 4a holds a casting object to be held. As a holding method, it may be gripped by a pair of arms or the like, but from the viewpoint of reducing the load applied to the punched material that tends to collapse as much as possible, suction is preferably performed by vacuum vacuum or the like. Under the control of the control unit 4d, the drive unit 4c displaces the moving arm 4b provided with the holding unit 4a at the tip in two dimensions in the rotational direction θ and the height direction H. Here, in order to operate the transfer machine 4, it is necessary to register information necessary for the operation of the transfer machine 4 in advance. The information includes the movement start points θin and Hin and the movement end point θout. , Hout. When moving the casting from the transport position C shown in FIG. 1 to the transport position D, the movement start points θin and Hin are set in accordance with the positions of the filling spaces 8d and 8e at the transport position C, and the movement end point. θout and Hout are set in accordance with the accommodation position in the decorative tray 9 which is moved to the conveyance path 3 and set at the conveyance position D. However, in the present embodiment, it is not necessary to individually register the movement start point and the movement end point for each of the molding objects because the two molding objects formed in the filling spaces 8d and 8e are collectively moved. That is, the position of the moving arm 4b that can hold the two punched objects at the same time is defined as the movement start points θout and Hout, and the position of the moving arm 4b that can be accommodated in the vanity plate 9 at the same time is defined as the movement end points θout and Hout. All you need is enough.

  The control unit 4d performs drive control of the moving arm 4b and suction control of the holding unit 4a according to the following operating conditions.

(Operating conditions)
(1) The moving arm 4b is raised after the holding is started at the movement start points θin and Hin.
(2) The moving arm 4b is rotated to the movement end point θout while maintaining the holding state.
(3) The holding is finished after the moving arm 4b is lowered to the height Hout.

  As a result, the punched article present in the filling space 8d at the transport position C moves to the transport position D and is accommodated in a predetermined position in the decorative tray 9 set at this position D. At the same time, the punched article present in the filling space 8e at the transport position C also moves to the transport position D and is accommodated in a predetermined position in the decorative tray 9 set here. The decorative dishes 9 are arranged on the conveyance path 3 at a predetermined interval, and the decorative dishes 9 move intermittently on the conveyance path 3 in the order of the conveyance positions D and E.

  In the present embodiment, as the transfer machine 4, a type that rotates the moving arm 4b is illustrated, but a type that slides the moving arm 4b may be used. In this case, a one-dimensional slide position may be defined instead of the rotational position θ.

  Next, a series of work contents focusing on one work object will be described along a time-series flow of the automatic production line 1.

  First, when the turntable 2 rotates and the work target is set at the transfer position A, a filling process is executed. In this step, as shown in FIG. 3, the lower mold 8b is lowered with respect to the upper mold 8a, and the two filling spaces 8d and 8e are close to each other in a separated state. The filling machine 5 arranged immediately above the filling spaces 8d and 8e discharges dry or wet powder cosmetics having different colors and fills them in the filling spaces 8d and 8e. At that time, it is preferable to improve the productivity because it is possible to reduce the number of work steps when the powder cosmetics are simultaneously filled in the filling spaces 8d and 8e, compared to the case where these are separately carried out (however, it is preferable that the separate steps are performed). It does not exclude the conversion).

  After completion of the filling process, the work object is transferred from the transfer position A to the transfer position B by the rotation of the turntable 2. In this conveyance process, as shown in FIG. 4, the tip (lower end) of the discharge port in the filling machine 5 is relatively moved while being in contact with the upper surface of the upper mold 8a. Thereby, the upper part of the filled powder cosmetic is scraped off, and the powder cosmetic is quantitatively filled in each of the filling spaces 8d and 8e. The scraping direction at that time is a direction along the color boundary (a direction that does not straddle the color boundary) so that the color mixture of the powder cosmetic does not occur.

  Then, when the work target reaches the transfer position B, a preliminary pressing step is executed. In this step, as shown in FIG. 5, the two powder cosmetics filled in the filling spaces 8d and 8e are integrally displaced by the integrated press head 6a of the preliminary press machine 6, that is, the plurality of press heads 6a. Are pressed together. Since this press is intended for solidification to the extent that the transfer machine 4 can handle it, a looser pressurization is sufficient than the press in the subsequent process. By stamping the filling materials in the filling spaces 8d and 8e at the same time, two castings having different color tones are formed simultaneously.

  In this preliminary pressing step, as shown in FIG. 6, a press for each filling material in the filling spaces 8d and 8e is performed using an independent press head having a plurality of press heads 6a and 6b that can operate independently from each other. You may change the conditions. As a result, the amount of the powder cosmetic can be changed according to the prescription of each filling, and the press pressure can be made different, and the press can be optimized for each prescription of the powder cosmetic. . In this case, it is not always necessary that the height (upper surface) of the filling after pressing is the same.

  Next, the work object is transferred from the transfer position B to the transfer position C by the further rotation of the turntable 2. In this conveyance process, the lower mold 8b is raised by relatively displacing the lower mold 8b with respect to the fixed upper mold 8a. Then, when reaching the transport position C, the lower mold 8b is completely raised as shown in FIG. As means for displacing the lower mold 8b up and down, typically, a guide rail with undulations provided along the turntable 2 (the lower mold 8b moves up and down by sliding contact therewith) is used. However, it may be displaced directly by an actuator or the like. As the lower mold 8b rises, the punch 10 formed in the filling spaces 8d and 8e also rises.

  In the state shown in FIG. 7, the upper surfaces of the upper and lower molds 8 a and 8 b protrude from the upper surface of the mold 8. By projecting and exposing in this way, the transfer tool 4 can hold the castings 10 and 11 without breaking them. Since all work objects transported by the turntable 2 always pass the transport position C, they are uniquely specified as a common position. Further, the positions of the filling spaces 8d and 8e at the transfer position C are also uniquely specified. Therefore, the positions and orientations of the castings 10 and 11 exposed on the transport position C are made uniform for all work targets.

  Next, the transfer machine 4 moves the castings 10 and 11 exposed on the transport position C to the transport position D and accommodates them in the dressing tray 9 set at the transport position D. This transfer to the decorative tray 9 is synchronized with the rotation of the turntable 2 and the movement of the conveyance path 3, and in the present embodiment, these are stopped. Specifically, as shown in FIG. 8, first, the movable arm 4b positioned at the rotation angle θin is lowered to a height equivalent to Hin, and then the castings 10 and 11 on the transport position C are held by the holding portion 4a. Are sucked and held at the same time. At this time, when the heights of the casting objects 10 and 11 are the same, the tip positions of the two holding portions 4a may be aligned. In order to adjust the vertical gap, the tip position of each holding portion 4a is changed. This adjustment may be performed by an operating mechanism that variably adjusts the height of the holding portion 4a.

  Next, the moving arm 4b is rotated and moved to the rotation angle θout while maintaining this holding state. Finally, after the movable arm 4b is lowered to the height Hout, the punched objects 10, 11 held by the holding portion 4a are simultaneously released. As a result, as shown in FIG. 9, the castings 10 and 11 are accommodated inside the decorative tray 9 set on the transport position D. In the illustrated case, a partition for separating the individual castings 10 and 11 is not provided in the dressing plate 9, but the dressing plate 9 provided with the partition may be used. Moreover, you may perform transfer of the castings 10 and 11 in this process not only with the empty cosmetic dish 9, but with the cosmetic dish 9 in which other cosmetics were already accommodated in part. In this case, the empty space of the decorative tray 9 becomes the accommodation destination (movement destination) of the castings 10 and 11.

  Thereafter, the work target is transported from the transport position C to the transport position D by the movement of the transport path 3. Then, when the work target reaches the transport position D, the pressing process is performed. In this step, as shown in FIG. 10, the castings 10 and 11 accommodated in the decorative tray 9 are pressed together by the press machine 7. As a result, the gap between the castings 10 and 11 in the decorative tray 9 is eliminated, and a multicolor cosmetic as a final casting product is completed.

  As described above, according to the present embodiment, by using the transfer machine 4 to automate the work of transferring the punched articles 10 and 11 into the decorative dish 9, it is compared with the case where this is performed manually. Thus, productivity can be improved. In a state where a large number of castings are accommodated in a tray or the like, the receiving positions of the individual castings are various, so that the receiving positions cannot be uniquely identified, and the castings are destroyed when they are taken out. These have been problems that hinder automation. Therefore, in the present embodiment, the transfer table 4 holds the movement sources (movement start points) holding the punched articles 10 and 11 at the positions of the filling spaces 8d and 8e at the known transfer position C, and the turntable 2 Is common to all work objects (molded objects 10 and 11) flowing through the conveyance path including In addition, at this movement source, the positions and orientations of all work objects are uniform. By fixing the movement source and making the arrangement of the castings 10 and 11 uniform, the castings 10 and 11 can be transferred without complicating the control of the transfer machine 4. Become. At the same time, since it is not necessary to apply an excessive load to the castings 10 and 11 during the transfer, the collapse of the castings 10 and 11 can be suppressed.

  In the above-described embodiment, the transfer machine 4 is exemplified by a multi-head type (having a plurality of holding portions 4a) that simultaneously holds and moves the castings 10 and 11, but is shown in FIG. As described above, a single head type (one having a single holding portion 4a) that holds a single punched article may be used. In this case, a sequential operation is performed in which the transfer of the casting is repeated by the number of the castings. As information necessary for operating the transfer machine 4, a set of information including a movement start point and a movement end point is registered with an execution order corresponding to the number of stamped objects.

  Further, as shown in FIG. 12, at least one movable mechanism 4e to 4g is provided on the moving arm 4b of the transfer machine 4, and the positions or orientations of the castings 10 and 11 to be transferred are different from those at the movement start point. You may make it change to a state. The first movable mechanism 4e variably adjusts the extension length of the moving arm 4b. The second movable mechanism 4f variably adjusts the rotational position of the head portion with respect to the moving arm 4b. The third movable mechanism 4g variably adjusts the distance between the pair of holding portions 4a. These movable mechanisms 4e-4g operate | move by an actuator, a stepping motor, etc. under control of the control part 4d according to the preset operation condition. As a result, the position or orientation that matches the arrangement in the decorative tray 9 can be arbitrarily set without depending on the positions and orientations of the castings 10 and 11 on the transport position C. In particular, as shown in FIG. 13, if the distance between the pair of holding portions 4a is adjusted by the third movable mechanism 4g, the clearance between them can be optimized when the molds 10 and 11 are set on the decorative tray 9. . In general, the expansion ratio of the moldings 10 and 11 (the degree to which the pressed molding is re-expanded after pressing) varies depending on the formulation. When designing the molds 8 for molding the castings 10 and 11, it is necessary to consider this expansion rate, but it is not easy to design a mold in anticipation of this. Moreover, since the clearance between the two changes in accordance with the re-expansion of the castings 10 and 11, this becomes a problem when being accommodated in the decorative dish 9. These problems can be solved by adjusting the clearance between the punched objects 10 and 11 by the third movable mechanism 4g.

  As described above, the method for producing a multicolor cosmetic according to the present invention can be widely applied to uses for improving productivity by automating the production line.
