Description

The present invention relates to an object support device for peripheral surface processing used for processing the peripheral surface of an object.

Compact containers and lipstick containers that contain cosmetics are required not only to have functionality, but also to have a design that looks good and reflects the product image. In order to meet such demands, for example, a metal thin film layer is formed by aluminum vapor deposition or the like to give a metallic luster to the lid of a compact container, or a transfer sheet on which a complicated color pattern is printed is attached. By making full use of various technologies, such as those made from aluminum, those with enhanced eye-catching effect on the appearance of the container have been proposed.

Recently, in order to impart a more complicated pattern, a part of the metal thin film layer or the transfer sheet is removed by laser irradiation, and the removed part is formed on the ground part or the ground part of the container. Characters and patterns are formed by exposing the colored layer (see, for example, Patent Document 1). Further, after forming an uneven pattern on the surface of the molded body in advance and forming a coating layer such as a metal thin film layer on the surface, the coating layer is partially removed by laser irradiation according to the unevenness of the uneven pattern. , It has been proposed to obtain a more impressive uneven pattern (see, for example, Patent Document 2).

By the way, such surface decoration usually assumes that the surface of the molded product is flat or has a very gentle fold curved surface, but recently, the entire outer peripheral surface of the cosmetic container has been laser-processed. It is being considered to give a beautiful decoration. Most of the outer peripheral surface of the cosmetic container is formed into a columnar shape, such as a lipstick container, a mascara container, a jar container, and a bottle container.

Therefore, in order to perform laser processing on the outer peripheral surface of such a cylindrical container, a commercially available laser processing machine for cutting or marking a cylindrical or cylindrical workpiece (for example, Patent Document 3). 4) can be diverted.

Next, a mode for carrying out the present invention will be described. However, the present invention is not limited to the following embodiments.

The object support device for peripheral surface processing of the present invention can be used when processing the main body 1 and the lid 2 of the mascara container, for example, as shown in FIG. This mascara container includes a bottomed tubular main body 1 for accommodating mascara liquid and a topped tubular lid 2 that is detachably fitted to the upper end of the main body 1. The outer peripheral surface of the portion 1 is slightly reduced in diameter toward the bottom. A mascara coating tool extending downward is fitted and fixed to the inside of the lid portion 2, but the mascara coating tool has nothing to do with the peripheral surface processing which is the object of the present invention, and is illustrated and described. Is omitted.

As shown in FIG. 2, both the main body 1 and the lid 2 of the mascara container are on the surfaces of the base bodies 3 and 4 made of a resin molded body [polypropylene (PP) resin in this example] colored in red, as shown in FIG. The metal thin film layers 5 and 6 formed by depositing aluminum are formed through the colorless and transparent undercoat layer 10, and a metallic gloss color is imparted as a whole. Then, a part of the metal thin film layers 5 and 6 is removed in a slit shape, and a band-shaped notch pattern S is formed in each of the main body portion 1 and the lid portion 2 as shown in FIG. .. Further, a concave-convex pattern T that rises in a convex shape is formed on the lid portion 2, and a part of the uneven pattern T is removed in a slit shape to form a notch pattern R.

The lid portion 2 will be described in more detail. First, on the side peripheral surface (hereinafter, simply referred to as “peripheral surface”) 2a of the lid portion 2, flowers and petals are shown on the lower side as shown in FIG. 3 in which this surface is expanded and shown in a plane. The pattern rises from the surroundings and is formed in a relief shape (concave and convex pattern T). Then, a first notch pattern R composed of diagonal slits is formed in the portion showing the flower. Further, on the upper side of the first notch pattern R, a second notch pattern S composed of vertical striped slits is formed in a band-shaped region continuously extending in the circumferential direction.

As shown in FIG. 4A, the first notch pattern R is partially formed as if the bulge of the uneven pattern T showing a flower is shaded. The notch pattern R is composed of diagonal slits, that is, notch openings 7 each of which is linear, and in each notch opening 7, the metal thin film layer 6 is removed, and the metal thin film layer 6 is removed from the notch opening 7. The colorless and transparent undercoat layer 10 is exposed, and the surface of the base body 4 colored in red underneath is transparent and is seen as a red line. Further, the notch pattern S (see FIG. 1) of the lid portion 2 is also formed by the linear notch opening 7, and is seen as a red line.

The lid portion 2 can be obtained, for example, as follows. That is, first, a red-colored PP resin is used as the resin material, and a relief-like uneven pattern T that three-dimensionally shows flowers and petals is formed on the peripheral surface 2a of the lid portion 2. Prepare the base body 4 of. For molding the base body 4, an appropriate molding method such as injection molding by a mold, injection blow molding, blow molding or the like is used.

Next, an undercoat layer 10 is formed on the top surface and the peripheral surface of the base body 4 using a colorless and transparent resin composition for undercoating, and aluminum is vapor-deposited on the surface of the undercoating layer 10. The metal thin film layer 6 is formed. Then, the predetermined portion of the metal thin film layer 6 is irradiated with a laser, and as shown in FIG. 4B, the metal thin film layer 6 is partially volatilized and removed to form notch patterns R and S [FIG. 3. See FIG. 4 (a)]. The removal processing of the metal thin film layer 6 by laser irradiation is performed by inputting data on the position to be processed in advance into the laser apparatus and intermittently scanning the laser beam based on the data. At this time, by using the object support device for peripheral surface processing of the present invention (hereinafter, may be simply referred to as “device”), the processing can be performed easily and beautifully.

That is, in the above laser processing, for example, using the apparatus shown in FIG. 5, laser irradiation is performed while rotating the base body 4 on which the metal thin film layer 6 is formed. More specifically, the apparatus includes a base 20 and three vertical walls 21, 22, 23 provided at predetermined intervals with respect to the base 20, and the base body is formed by the vertical walls 21, 22. The motor 12 that gives the rotation operation to 4 is fixed horizontally. Further, a rotation shaft (not visible in the figure) of the motor 12 projects to the right side of the vertical wall 22, and a disk-shaped rotation base 24 that rotates integrally with the rotation shaft is connected to the tip thereof. Has been done. In the following figures, the undercoat layer 10 provided under the metal thin film layer 6 is not shown.

An object fitting guide 25 for mating with the opening side of the base body 4 to be processed and transmitting rotation is detachably attached to the rotating base 24, and the vertical wall 23 is attached to the vertical wall 23. An object holding guide 26 that presses the top surface side of the base body 4 to hold the base body 4 in a rotatable posture is attached. The object fitting guide 25 and the object holding guide 26 support the base body 4 horizontally and rotate integrally with the rotating base 24.

As shown in FIG. 6A, the object fitting guide 25 is fitted with a flange portion 30 for attaching the object fitting guide 25 to the rotary base 24 and a hollow portion of the base body 4. A support shaft 31 that horizontally supports the base body 4 and an extension shaft 32 of the flange portion 30 that extends coaxially to the side opposite to the side on which the support shaft 31 extends are provided. The support shaft 31 and the extension shaft 32 are coaxially connected to the rotation shaft of the motor 12 via the rotation base 24.

Further, a notch portion 40 penetrating the flange portion 30 in the thickness direction is provided at the root portion of the support shaft 31 in the flange portion 30, and the notch portion 40 is used to be used in FIGS. 6 (b) to 6 (b). The stopper 33 shown in (d) is slidably attached along the peripheral surface of the extension shaft 32. Note that FIG. 6B is a vertical cross-sectional view of the stopper 33 as in FIG. 6A, FIG. 6C is a left side view of the stopper 33, and FIG. 6D is a front view of the stopper 33.

That is, the stopper 33 has a ring portion 33a that is externally fitted to the extension shaft 32 of the object fitting guide 25, and a claw portion 33b that penetrates the notch portion 40 and enters the inside of the opening of the base body 4. I have. Then, the ring portion 33a is pressed and urged toward the base body 4 side by a compression spring 34 sandwiched between the rotation base 24 and the ring portion 33a, as shown by an arrow X.

On the other hand, on the inner peripheral surface of the opening of the base body 4, a female screw portion 36 for screw engagement with the male screw portion 35 (see FIG. 2) provided on the main body 1 side is provided, and a part thereof is provided. , A concave groove 37 is formed by being cut out in the axial direction. The concave groove 37 is generally provided for positioning in the circumferential direction when giving a pattern to the surface of the lid portion 2 or when determining the arrangement of screws at the time of screw processing. The stopper 33 is described above. The claw portion 33b of the above has a shape that just fits into the concave groove 37. Therefore, when the base body 4 is attached to the support shaft 31 of the object fitting guide 25 and lightly turned in the circumferential direction, the claw portion 33b of the stopper 33 snaps into the notch groove 37 on the base body 4 side. The base body 4 is fixed by entering, and the base body 4 is prevented from rotating.

Further, the object holding guide 26 (returning to FIG. 5) that supports the top surface side of the base body 4 has a pressing body 38 having a conical tip and pressing the pressing body 38 against the base body 4 side. It is provided with a shaft portion 39 that holds the shaft portion 39 in a closed state. A horizontal surface portion 23a extends in the horizontal direction at the lower end of the vertical wall 23 to which the object holding guide 26 is attached, and the base is adjusted by adjusting the attachment position of the horizontal surface portion 23a with respect to the base 20. The vertical wall 23 can be positioned so as to be able to rotatably support the base body 4 with an appropriate pressing force against the top surface of the body 4.

In this way, the rotatably supported base body 4 is arranged directly under the output unit 50 of the laser device, and as shown by the arrow, the laser beam is irradiated vertically toward the surface of the base body 4. As a result, the notch patterns R and S can be imparted to the surface of the base body 4 by partially removing the metal thin film layer 6 provided via the undercoat layer 10 (see FIGS. 1 and 3). ).

In the above laser processing, for example, as shown in FIG. 7A, the surface of the base body 4 on which the metal thin film layer 6 is formed is virtually divided into three in the circumferential direction, and first, 1/3 of the entire peripheral surface is formed. Laser irradiation is performed on the region of 1 from directly above to partially form notch patterns R and S (the portion shown as X1 in FIG. 3). Next, the base body 4 is rotated by 120 ° and laser irradiation is performed in the same manner, and the portion shown as X2 in FIG. 3 is processed. Further, the base body 4 is rotated by 120 ° and laser irradiation is performed in the same manner, and the portion shown as X3 in FIG. 3 is processed. Note that P is the central axis of rotation [the same applies to FIG. 7B].

In this way, the entire peripheral surface of the base body 4 on which the metal thin film layer 6 is formed is processed, and the lid portion 2 in which the notch patterns R and S are formed on the peripheral surface 2a as shown in FIG. Can be obtained. As shown in FIG. 7A, the notch openings 7 of the obtained notch patterns R and S are irradiated with laser in a state where the peripheral surface portions that are virtually divided into three are arranged directly above each. In order to receive, it is formed vertically downward in its arrangement.

As described above, the surface of the base body 4 is divided into n in the circumferential direction (three divisions in the above example) with respect to the base body 4 on which the metal thin film layer 6 is formed, and the base body 4 is divided into (360 / n). ) ° When the laser irradiation is performed intermittently by rotating n times, the amount of processing data handled for one laser irradiation becomes 1 / n when the entire circumference is processed at one time, which is a short time. It will be an intermittent process at. Therefore, the timing of transporting the processed product can be shortened, and the production efficiency can be improved. However, since the laser irradiation becomes intermittent, care must be taken not to shift the notch pattern at the start point and the end point of the laser irradiation.

Further, depending on the materials of the undercoat layer 10 and the base body 4 from which the metal thin film layer 6 is removed and exposed, the diffusely reflected light generated during laser irradiation is shown by the chain line E in FIG. 7A, as shown by the chain line E, the undercoat layer 10 (Not shown) and the base body 4, and further refracted and incident on the metal thin film layer 6, there is a possibility that a notch opening is formed at a portion other than the portion to be removed. Therefore, in consideration of the type of laser, the materials of the undercoat layer 10 and the base body 4, and the like, care must be taken not to set the laser irradiation region too wide.

Alternatively, by selecting an appropriate material and color as the support shaft 31 [see FIG. 6A] of the object fitting guide 25 to be fitted with the hollow portion of the base body 4, such a method may be obtained. It is possible to devise so that diffused reflection of the laser beam does not occur as much as possible.

Further, when the surface of the base body 4 on which the metal thin film layer 6 is formed is irradiated with the laser, the laser irradiation is not performed intermittently in n times as described above, but is shown in FIG. 7 (b). As described above, laser irradiation can be performed while rotating the base body 4, and a notch pattern can be continuously formed on the entire peripheral surface. The notch openings 7 of the notch patterns R and S (see FIGS. 1 and 3) thus obtained are all formed toward the rotation center axis P as shown in the drawing.

According to this method, unlike the case where the laser irradiation is performed intermittently as described above, it is not necessary to worry about the deviation of the notch pattern at the boundary where the processing is interrupted, and any part of the peripheral surface is beautiful. It will be a good finish. However, depending on the design of the notch patterns R and S, the amount of processing data handled for one laser irradiation becomes enormous, and one processing takes time. Depending on the amount of processing per unit time, it is desirable to properly use whether to perform laser irradiation intermittently by dividing into n as described above, or to continuously process the entire circumference at one time.

The entire lid 2 (see FIG. 1) thus obtained has a metallic luster due to the metal thin film layer 6, and a part of the peripheral surface thereof is raised to relieve the pattern of flowers and petals. It has a concave-convex pattern T. Then, since the notch pattern R formed of the red diagonal slits is formed so as to partially overlap the uneven pattern T and emphasize the unevenness, the unevenness is emphasized. In addition, the notch pattern S consisting of red vertical striped slits creates a unified design with a flow in the circumferential direction.

In particular, since the notch openings 7 of the notch patterns R and S are formed in a specific direction with respect to the rotation center axis P (see FIG. 7) of the base body 4, the metal thin film layer 6 is cut. There is regular uniformity in the angle between the missing open end face and the exposed open face. Therefore, although the notch patterns R and S are composed of fine diagonal lines and vertical stripes, all the parts are clearly expressed, and in combination with the relief-like uneven pattern T, the eye is excellent. Demonstrates a catching effect.

Further, the main body 1 (see FIGS. 1 and 2) to be combined with the lid 2 also has a base body 3 for the main body 1 having a metal thin film layer 5 formed on the outer peripheral surface, similarly to the lid 2. It can be obtained by preparing, irradiating the surface with a laser, and partially removing the metal thin film layer 5 to form a notch pattern S.

In the above laser machining, the peripheral surface machining object support device shown in FIG. 5 is used as in the case of obtaining the lid portion 2, but the base body 4 of the lid portion 2 and the base body 3 of the main body portion 1 are used. Since the shapes thereof are different, the object fitting guide 25 and the stopper 33 for the lid portion 2 are replaced with the object fitting guide and the stopper for the main body portion 1.

As shown in FIG. 8, the object fitting guide 45 for the main body 1 is fitted with the flange portion 50 for attaching the object fitting guide 45 to the rotary base 24 and the hollow portion of the base body 3. A support shaft 51 that horizontally supports the base body 3 and an extension shaft 52 of the flange portion 50 that extends coaxially to the side opposite to the side on which the support shaft 51 extends are provided. The support shaft 51 and the extension shaft 52 are coaxially connected to the rotation shaft of the motor 12 (see FIG. 5) via the rotation base 24.

Further, a stopper block 53 for stopping the rotation of the base body 3 is attached to the surface of the flange portion 50 (the surface on the side where the support shaft 51 extends). The stopper block 53 is a box-shaped case cover 54 attached to the surface of the flange portion 50 and elastically held inside the box-shaped case cover 54, as shown in FIG. 9, which is an enlarged view of a cross section taken along the line AA of FIG. It is provided with a stopper 55 to be formed. That is, the stopper 55 is pressed and urged by the compression spring 56 and the bolt cap 57 toward the base body 3 side as shown by the arrow X'in the figure, and the pressing force is the adjusting bolt that presses the bolt cap 57. It is adjusted according to the degree of screwing of 58.

On the other hand, a concave groove 59 is formed on the outer peripheral surface of the male screw portion 35 (see FIG. 2) of the base body 3 which is the main body portion 1 by cutting out a part thereof in the axial direction. The concave groove 59 is similar to the concave groove 37 (see FIG. 6) provided in the female thread portion 36 of the base body 4 serving as the lid portion 2, and is used when giving a pattern to the surface of the main body portion 1 or when threading. When deciding the arrangement of the screws, which is generally provided for positioning in the circumferential direction, the tip portion 55a of the stopper 55 has a shape that just fits into the concave groove 59. Therefore, when the base body 3 is attached to the support shaft 51 of the object fitting guide 45 and lightly turned in the circumferential direction, the tip portion 55a of the stopper 55 snaps into the concave groove 59 on the base body 3 side. The base body 3 is fixed by the above, and the base body 3 is prevented from rotating.

Further, as the object holding guide for supporting the top surface side of the base body 3, the same product as the object holding guide 26 used for laser machining of the base 4 for the lid 2 can be used (FIG. 5). return). However, by adjusting the position of the vertical wall 23 provided with the object holding guide 26, that is, the mounting position of the horizontal surface portion 23a with respect to the base 20, an appropriate pressing force is applied to the top surface of the base body 4. The vertical wall 23 is positioned so that the base body 3 can be rotatably supported.

The base body 3 rotatably supported in this way is arranged directly under the output unit 150 (see FIG. 5) of the laser device and toward the surface of the base body 3 as in the case of obtaining the lid portion 2. By irradiating the laser beam vertically, the metal thin film layer 5 provided via the undercoat layer 10 can be partially removed from the surface of the base body 3 to impart a notch pattern S (FIG. 6). See 1).

Similar to the lid portion 2, the main body portion 1 thus obtained also has a metallic luster as a whole due to the metal thin film layer 5, and a notch pattern composed of red vertical striped slits on a part of the peripheral surface 3a thereof. S is given. Therefore, the mascara container as a whole has a unified design with a flow in the circumferential direction. As with the notch pattern S of the lid portion 2, every portion of the notch pattern S of the main body portion 1 is clearly expressed, and an excellent eye-catching effect is exhibited.

As described above, according to the peripheral surface processing object support device used for laser processing of the mascara container, the object fitting guide 25 for the lid portion 2 and the main body portion 1 to be processed, respectively. 45, a stopper 33,55 (including stopper block 53) and is provided with, by simply replacing the these, the lid portion 2 and the main body 1 sequentially be beautifully processed in a simple and accurate can. Further, the object holding guide 26 shared for processing the lid portion 2 and the main body portion 1 only needs to be positioned and adjusted according to the object, and is easy to handle and has good workability.

In the above example, a single object holding guide 26 is attached to the base 20 so as to be positionably adjustable, so that it can be used for both the processing for the lid portion 2 and the processing for the main body portion 1. However, as the object holding guide 26, a plurality of types having different horizontal lengths and shapes of the object holding portions are prepared, and appropriate ones are prepared according to the shape of the object and the holding position thereof. May be exchanged. Further, when the object can be fitted and held in a stable state only by the object fitting guide 25, it is not always necessary to use the object holding guide 26. However, if the object is held so as to be sandwiched between the object fitting guide 25 and the object holding guide 26 from both sides, the object can be processed in a more stable state without any axial deviation, which is preferable.

In the above example, the device of the present invention is applied to the processing of the main body 1 and the lid 2 of the mascara container, but in addition to these, various cosmetic containers for which the peripheral surface is beautifully processed. It is preferable to apply to. This is because cosmetic containers are often added with a unified design of beautiful uneven patterns and notch patterns on the peripheral surfaces of both the lid and the main body to increase added value.

Also in the case of processing these, a plurality of types of object fitting guides (25 in FIG. 5) , stoppers (33 in FIG. 6), and object holding guides (in FIG. 5) are processed according to the shape of the lid portion and the main body portion. If 26) is prepared, it is possible to easily perform processing with high accuracy simply by exchanging them according to the object, and the workability is good. Below are some examples of different types of object fitting guides.

For example, FIG. 10A shows an example of an object fitting guide used when processing a base body 60 having a large diameter and a relatively shallow diameter, which is a lid portion of a so-called jar container (wide-mouthed bottle). The object fitting guide 70 has basically the same configuration as the object fitting guide 25 shown in FIG. 6A, but since the diameter of the base body 60 is large, the hollow portion of the base body 60 The support shaft 72 that is fitted with the flange portion 71 and horizontally supports the base body 60 is formed of a hollow body having a ceiling tube shape that protrudes from the flange portion 71.

Then, the extension shaft 73 extends coaxially from the top surface portion 72a of the support shaft 72 (the portion that abuts on the top surface portion of the base body 60) toward the rotation base 24 side, and the motor 12 (the portion that abuts on the top surface portion of the base body 60) extends through the rotation base 24. (See FIG. 5) is coaxially connected to the rotating shaft.
