Description

Monolithic decorative sheet preparation device and injection molding system

The present invention relates to a one-piece decorative sheet preparation apparatus and an injection molding system including the same.

Conventionally, a decorative technique in which a decorative sheet is attached to a surface of an injection molded article while forming an injection molded article from a molten resin is known. In this technique, a pair of dies are prepared, and a decorative sheet is placed on one or both of the pair of dies, and molten resin is injected into the stencil space to perform injection molding. At this time, the transfer layer is transferred to the surface of the molded article while the injection molding is performed, thereby forming a decorative layer.

In the two-color molding, two kinds of molten molten resins having different colors or materials are sequentially injection-molded to produce two-color molded articles in which two kinds of molten resins are joined. Further, after the primary molding product to which the transfer layer is transferred is produced by the simultaneous molding process, a two-color molding simultaneous painting method of molding the molding resin twice on the decorative surface of the primary molded article is also known (for example, reference) Patent Document 1).

Patent Document 1: Japanese Laid-Open Patent Publication No. 2010-105211

In the two-color forming simultaneous drawing method described in Patent Document 1, a molding simultaneous decoration device having a first fixed mold, a second fixed mold, and two movable molds is used. The first fixed mold is used for one forming and the second fixed mold is used for secondary forming. The two movable molds change the position of the first fixed mold and the second fixed mold by rotation. In the apparatus described in Patent Document 1, a roll-shaped decorative sheet is provided to a fixed mold.

On the one hand, for example, the decoration of the decorative sheet is disposed on the movable mold side while the decorative technique is also known. At this time, if the decorative sheet is long, the device on the movable mold side tends to be enlarged according to the supply roller and the take-up roller. Therefore, it is preferred that the decorative sheet is not a long size but a one-piece form. However, for a one-piece decorative sheet, it is difficult to properly position the mold. Moreover, when positioning is performed by a robot inside the mold, a special time for positioning will be required in the forming cycle, and thus there is a problem that the forming cycle becomes long. Moreover, the sensor is mounted on the robot, and accordingly the structure of the robot becomes complicated.

An object of the present invention is to shorten the molding cycle in a simultaneous molding apparatus.

Hereinafter, a plurality of aspects will be described as means for solving the problem. These methods can be arbitrarily combined as needed.

A one-piece decorative sheet preparing device according to an aspect of the present invention is a device for preparing a one-piece decorative sheet that is conveyed by a robot to a forming simultaneous decorative device, comprising: a base body, a cutting device, a holding table, and a position detecting device. Device, positioning device. The cutting device produces a one-piece decorative sheet by cutting a long decorative sheet. The holding table has a holding surface capable of holding a one-piece decorative sheet. The position detecting device detects the position of the one-piece decorative sheet held by the holding surface of the holding table. The positioning device positions the one-piece decorative sheet relative to the substrate based on the position detection result.

Further, here, the one-piece decorative sheet includes a transfer sheet in which the base sheet is peeled off and does not remain on the product, and a laminate sheet in which the base sheet remains on the product.

In the device, it is possible to prepare the outer side of the decorative device while forming A one-piece decorative sheet that is positioned correctly. Thereby, the positioning operation of the one-piece decorative sheet can be performed in parallel with the forming operation of the simultaneous molding apparatus. As a result, the molding cycle of the simultaneous molding apparatus can be shortened.

The holding table can also be mounted in a manner movable relative to the substrate in a predetermined plane. At this time, the positioning device can adjust the position of the holding table in order to position the one-piece decorative sheet with respect to the base.

The position detection by the position detecting device and the positioning by the positioning device can also be performed a plurality of times. In this device, the positioning accuracy of the one-piece decorative sheet will be improved.

The position detecting device may also have a plurality of detecting means for detecting one end portion of the one-piece decorative sheet. In this device, since a plurality of detecting devices are provided only on one side of the one-piece decorative sheet, the overall structure and wiring of the device are simplified.

The one-piece decorative sheet preparation device may further have a robot positioning member for positioning the robot relative to the base when the robot takes out the one-piece decorative sheet from the holding table. In this device, the robot is mechanically positioned relative to the substrate by the robot positioning member, so that the robot can accurately maintain the one-piece decorative sheet.

The one-piece decorative sheet preparing device may further have a take-up device for taking out the long decorative sheet to the holding surface of the holding table. At this time, the cutting device may cut the long decorative sheet in a state in which the long decorative sheet is taken out.

The take-up device may have a grip portion for holding the front end of the long decorative sheet and a moving portion for moving the grip portion to take out the long decorative sheet.

The grip portion may also have a metal surface that is in contact with the first side of the long decorative sheet and a rubber surface that is in contact with the second side of the long decorative sheet. The dress Centering, for example, the rubber surface is in contact with the base sheet of the long decorative sheet, and the metal surface is in contact with the decorative layer of the long decorative sheet. As a result, not only the holding force is sufficiently increased, but also the peeling of the decorative layer is hard to occur.

The one-piece decorative sheet preparing device may further have a jig device to sandwich the front end of the long decorative sheet before the long decorative sheet is taken out by the take-up device. At this time, the clamp device may have a first toothed portion at which the front end of the long decorative sheet is located, and the grip portion may have a second toothed portion that is engaged with the first toothed portion. Further, when the grip portion grips the front end of the long decorative sheet, the second tooth portion is located at a position to be engaged with the first tooth portion. In this apparatus, since the first toothed portion of the clamp device maintains the posture of the front end of the long decorative sheet, the grip portion can reliably hold the front end of the long decorative sheet. Further, according to the shape of the second toothed portion of the grip portion, a sufficient clamping force can be secured.

The one-piece decorative sheet preparing device may further have a cable to restrict the movement of the long-sized decorative sheet when the take-up device takes out the long-sized decorative sheet, thereby preventing the long-sized decorative sheet from coming off the holding surface. In this apparatus, when the long-sized decorative sheet is taken out, the long-sized decorative sheet is difficult to be detached from the holding surface by the cable, so that the long-sized decorative sheet is less likely to curl.

The holding table may further have a plurality of holes and suction means open on the holding surface, and the adsorption means suctions the one-piece decorative sheet on the holding surface by sucking air from the plurality of holes. In this device, the adsorption device adsorbs the monolithic decorative sheet on the holding surface by taking in air from a plurality of holes.

The adsorption device may also change a region that is adsorbed through a plurality of holes in accordance with the size of the one-piece decorative sheet. In this apparatus, since the area to be adsorbed can be changed as needed, vacuum suction is not performed in a futuristic manner when a small-sized monolithic decorative sheet is used.

The adsorption device can also stepwise increase or decrease the area of adsorption through a plurality of holes. In this apparatus, for example, before, during, or after the monolithic decorative sheet is adsorbed to the holding surface, the sheet can be placed along the holding surface by stepwise adsorption.

The one-piece decorative sheet preparation device may further have a roller so that the one-piece decorative sheet is along the holding surface. In this apparatus, when the one-piece decorative sheet is adsorbed to the holding surface, the sheet can be passed along the holding surface by the roller.

An injection molding apparatus according to another aspect of the present invention includes the above-described one-piece decorative sheet preparing device, a forming simultaneous decorative device which is formed by using a one-piece decorative sheet, and is simultaneously formed from a one-piece decorative sheet preparing device A robot that transports a single-piece decorative sheet.

In this device, it is possible to prepare a one-piece decorative sheet which is accurately positioned on the outer side of the forming and simultaneously decorating device. Thereby, the positioning operation of the one-piece decorative sheet can be performed in parallel with the forming operation of the forming simultaneous decorative device. As a result, the molding cycle of the simultaneous molding apparatus can be shortened.

The forming simultaneous decorating device may also have a second robot positioning member for positioning the robot in the forming and decorating device when the robot carries the monolithic decorative sheet into the forming and decorating device. In this device, the robot can be mechanically positioned in both the one-piece decorative sheet preparation device and the formed simultaneous decoration device, respectively. According to this, it is not necessary to provide a camera for position adjustment by the robot itself on the robot.

(3) Control action of the single-piece decorative sheet preparation device

The operation of the various devices that control the one-piece decorative sheet preparation device 3 by the control unit 61 will be described with reference to Fig. 5 . Fig. 5 is a flow chart showing a control operation for preparing a one-piece decorative sheet.

In the initial state, as shown in FIG. 6, the front end 23 of the long decorative sheet 19 is in a state of being held by the clamp member 27 and held. Fig. 6 is a side view showing a state in which a jig member holds a front end of a long decorative sheet. Further, before the step S1, in the cable supply device 49, the cable housing portion 51 is moved to a position separated from the clamp member 27.

In step S1, the control unit 61 transmits a control signal to the moving unit 43 and the chuck driving device 63, thereby holding the long portion on the chuck portion 39 as shown in Fig. 7 . The front end 23 of the decorative sheet 19 is sized.

In step S2, the control unit 61 transmits a control signal to the jig driving device 65 to cause the jig driving device 65 to open the jig member 27.

In step S3, the control unit 61 transmits a control signal to the moving unit 43, thereby moving the chuck portion 39 to the upper cutting position as shown in Figs. 2 and 3 . Here, the control unit 61 determines the case where the chuck portion 39 is moved to the cutting position based on the detection result from the cutting sensor 60 (FIG. 4). The long-sized device sheet 19 is pulled up along the holding surface 13. Then, as shown in FIG. 3, the cable housing portion 51 of the cable supply device 49 is moved to the holding surface 13 side.

In step S4, the control unit 61 transmits a control signal to the jig driving device 65 to close the clamp member 27. According to this, the lower end portion of the drawn long decorative sheet 19 is sandwiched.

In step S5, the control unit 61 causes the cutting device 47 to cut the lower end portion of the long decorative sheet 19 by transmitting a control signal to the cutting device 47. According to this, the one-piece decorative sheet 141 is obtained from the long decorative sheet 19.

In step S6, the control unit 61 transmits a control signal to the moving unit 43, and moves the chuck unit 39 to a predetermined position above. As a result, the long-sized sheet 19 is further pulled up along the holding surface 13. At the time of pulling, the cable 55 is located in the vicinity of the holding surface 13, whereby the long decorative sheet 19 is difficult to come off the holding surface 13. Thereby, the long decorative sheet 19 is difficult to curl.

In step S7, the control unit 61 transmits a control signal to the adsorption device 67 so that the adsorption device 67 adsorbs the one-piece decorative sheet 141 to the holding surface 13. Further, the control unit 61 transmits a control signal to the chuck driving device 63, so that the chuck driving device 63 releases the grip of the one-piece decorative sheet 141, and further moves the chuck member 41 downward. When doing this, the roller machine The structure 44 moves the roller to the holding surface 13 side so that the one-piece decorative sheet 141 is continuously attached to the holding surface 13 from top to bottom. Thereby, it is difficult to wrinkle the one-piece decorative sheet 141. Further, as shown in FIG. 9, the one-piece decorative sheet may be sequentially sucked from the portion where the one-piece decorative sheet 141 is pressed against the holding surface 13 by the roller mechanism 44. Fig. 9 is a cross-sectional view showing a state in which the roller mechanism presses the one-piece decorative sheet so that the one-piece decorative sheet is along the holding surface of the holding table.

In step S8, the one-piece decorative sheet 141 is positioned with respect to the base 5 at a predetermined position in the XY direction. Specifically, as shown in FIG. 10, the sensor unit 57 moves to the detection position to detect the position of the one-piece decorative sheet 141, and based on the result, the control unit 61 moves the holding table 11 to make a one-piece decoration. The sheet 141 is close to a predetermined position. Fig. 10 is a side view showing a state in which a one-piece decorative sheet is held by a holding table. Specifically, in order to position the one-piece decorative sheet 141 with respect to the base 5, the table drive mechanism 15 adjusts the position of the holding table 11. In the present embodiment, the above operation is repeated three times. Hereinafter, the position adjustment operation of three times will be described with reference to Figs. 11 to 13 . 11 to 13 are schematic diagrams showing the first position detection and position adjustment operation. More specifically, initially, the sensor unit 57 moves to the detection position (Fig. 10). As shown in Fig. 11, in the initial stage, the inclination angle of the one-piece decorative sheet 141 may become large. Therefore, the position and inclination of the one-piece decorative sheet 141 are corrected by moving the holding table 11 in the XY direction. Next, as shown in FIG. 12, the position and inclination of the one-piece decorative sheet 141 are further corrected by moving the holding table 11 in the XY direction with respect to the one-piece decorative sheet 141 whose inclination has become small. Finally, the positioning operation is completed by moving the holding table 11 having almost no inclination and the position in the up and down direction to be determined in the X direction. As such, the position detection by the sensor unit 57 The positioning of the machine table driving mechanism 15 will be performed a plurality of times, so that the positioning accuracy of the one-piece decorative sheet 141 can be improved. Here, the reason why such a plurality of position adjustment operations can be performed is that the positioning of the one-piece decorative sheet 141 is performed outside the molding apparatus 101 while being formed, thereby preparing the one-piece decorative sheet in parallel with the forming operation. 141, thereby enabling sufficient time for positioning.

In step S9, as shown in FIG. 14, the control unit 61 waits for the robot hand 131 to approach the holding surface 13 to adsorb the one-piece decorative sheet 141. Figure 14 is a side view of the one-piece decorative sheet preparation device. The proximity of the robot 131 can be detected by a detection signal from various sensors or by a signal from the robot 131. As shown in FIG. 14, the robot 131 has a support portion 140 and an adsorption portion 143 provided at the front end of the support portion 140. The adsorption portion 143 is formed in a square shape toward the holding surface 13 side. Further, a positioning hole 145 into which the positioning pin 71 can be inserted is formed in the support portion 140. By the engagement of the positioning pin 71 and the positioning hole 145, the positioning of the robot 131 relative to the base 5 will be mechanically performed. Therefore, the one-piece decorative sheet 141 can be accurately positioned and held relative to the robot 131. In this device, since the robot is mechanically positioned relative to the base 5 by the robot positioning member, the robot 131 can accurately hold the one-piece decorative sheet 141.

In step S10, the control unit 61 transmits a control signal to the adsorption device 67 to cause the adsorption device 67 to release the adsorption of the one-piece decorative sheet 141 by the holding surface 13.

In step S11, the control unit 61 waits for the robot hand 131 to move away from the holding surface 13 in a state of adsorbing the one-piece decorative sheet 141.

(4) Effect of the single-piece decorative sheet preparation device

(7) Control action of forming the simultaneous decoration device

The molding operation will be described with reference to Figs. 18 to 26 . Fig. 18 is a flow chart showing the control operation of forming the simultaneous decorating device. Figure 19 to Figure 26 are A schematic cross-sectional view showing a state of forming a simultaneous decorative device is shown.

In Fig. 19, the movable mold 105 is separated from the fixed mold 103 to secure a space between the two. Here, in FIG. 19, the primary molded product 147 (described later) is disposed in the first partial cavity 130 of the first movable mold 113.

In step S101, the control unit 161 waits for the robot 131 to enter between the second fixed mold 109 and the second movable mold 115. The entry of the robot 131 can be detected by a detection signal from various sensors 179, or can be detected based on a signal from the robot 131 (hereinafter, the position detection of the robot is also the same). As shown in FIG. 19, the robot 131 has a support portion 140 and an adsorption portion 143 provided at the front end of the support portion 140. The adsorption portion 143 faces the second movable mold 115 side and is formed in a square shape. The adsorption portion 143 is for adsorbing the one-piece decorative sheet 141. The four sides of the one-piece decorative sheet 141 are located further outward than the outer edge of the end surface of the adsorption portion 143. Further, a positioning hole 145 into which the positioning pin 139 can be inserted is formed in the support portion 140.

The one-piece decorative sheet 141 is composed of a base sheet 33 and a decorative layer 35 provided on the base sheet 33 (see Fig. 8). The decorative layer 35 has, for example, a surface protective layer, a pattern layer, and an adhesive layer. Moreover, the one-piece decorative sheet 141 may be provided with a peeling layer between the base sheet 33 and the decorative layer 35. The type of the one-piece decorative sheet 141 is, for example, a transfer sheet in which the base sheet 33 is finally peeled off from the product, and the base sheet 33 remains on the laminated sheet of the product. The thickness of the base sheet in the transfer sheet is 38 to 50 μm, and the thickness of the base sheet in the laminate sheet is 100 to 400 μm.

In step S102, the control unit 161 transmits a control signal by the jig driving device 175 to cause the jig driving device 175 to move the jig 133 (133a, 133b) to the open position separated from the first face 129. As shown in FIG. 19, the pair of first jigs 133a are moved obliquely outward, away from the first face 129.

In step S103, the control unit 161 transmits a control signal to the long decorative sheet driving device 177 to move the long decorative sheet driving device 177 to move the long decorative sheet 123 (cylindrical film) for the next forming operation.

The layer structure of the long-sized decorative sheet 123 may be the same as or different from the layer structure of the one-piece decorative sheet 141.

In step S104, as shown in FIG. 20, the control unit 161 waits for the robot hand 131 to move to the second movable mold 115 side, and as a result, the robot is in a state where the one-piece decorative sheet 141 abuts against the first surface 129. 131 stops. In the forming simultaneous decorating device 101, the positioning of the robot 131 and the second movable mold 115 is mechanically performed by the positioning pin 139 and the positioning hole 145, and thus the position of the one-piece decorative sheet 141 with respect to the second movable mold 115 The accuracy will be improved, and the transfer accuracy in the subsequent molding will be improved at the same time.

In step S105, the control unit 161 transmits a control signal to the flat surface suction device 171 so that the flat surface suction device 171 adsorbs the four sides of the one-piece decorative sheet 141 on the first surface 129. In this manner, since the first suction hole 135 is formed on the flat first surface 129, the supplied one-piece decorative sheet 141 can be held without offset.

In step S106, the control unit 161 transmits a control signal to the jig driving device 175 so that the jig driving device 175 arranges the jig 133 (133a, 133b) at the nip position in close contact with the first surface 129. As shown in FIG. 20, the pair of first jigs 133a are moved obliquely inside and contact the first face 129 as shown in FIG. As a result, the jig 133 (133a, 133b) presses the four sides of the one-piece decorative sheet 141 against the first surface 129. Thus, after the one-piece decorative sheet 141 is held on the flat first surface 129, by the jig 133 Mechanically fixed.

In step S107, the control unit 161 transmits a control signal to the product unit suction device 173, and as shown in Fig. 21, the one-piece decorative sheet 141 is brought into close contact with the first partial cavity 130, that is, the shape of the product.

In step S108, as shown in FIG. 21, the control unit 161 waits for the robot 131 to leave the second movable mold 115, and thereby exit the space between the fixed mold 103 and the movable mold 105.

In step S109, the control unit 161 transmits a control signal to the mold rotating device 163 to cause the mold rotating device 163 to rotate the movable mold 105 by 180 degrees. As a result, as shown in FIG. 22, the second movable mold 115 is opposed to the first fixed mold 107, and the first movable mold 113 is opposed to the second fixed mold 109.

In step S110, the control unit 161 transmits a control signal to the mold front-rear travel device 165 to move the mold front-rear travel device 165 toward the fixed mold 103 side. As a result, as shown in FIG. 23, the fixed mold 103 and the movable mold 105 are in close contact with each other.

In step S111, the control unit 161 transmits a control signal to the first resin injection device 167 to cause the first resin injection device 167 to inject the molding resin once into the first partial cavity 130. The primary molding resin flows between the one-piece decorative sheet 141 and the long decorative sheet 123, and becomes the first resin portion 145 after cooling. As a result, the primary molded article 147 is obtained in the primary molding portion 118.

As described above, in the apparatus, the first flat surface suction device 171 attracts the one-piece decorative sheet 141 through the flat first surface 129 of the second movable mold 115. Then, the jig 133 presses the one-piece decorative sheet 141 with respect to the second movable mold 115. Next, the product part suction device 173 will be mounted in a single piece. The trim sheet 141 is attracted to the first partial cavity 130. Finally, the first resin injection device 167 injects the molten resin into the first portion of the cavity 130. In the above steps, since the one-piece decorative sheet 141 is in close contact with the first partial cavity 130 of the second movable mold 115, positional displacement of the one-piece decorative sheet 141 is hard to occur.

Further, the control unit 161 transmits a control signal to the second resin injection device 169 to cause the second resin injection device 169 to inject the secondary molding resin into the second partial cavity 127. After cooling, the resin for secondary molding becomes the second resin portion 151 which is in close contact with one surface of the primary molded article 147 on the side of the long decorative sheet 123. As a result, the secondary molded article 153 can be obtained in the secondary molded portion 119. Here, FIG. 16 shows the initial manufacturing cycle of the simultaneous molding apparatus 101, and thus the secondary molded article has not yet been manufactured.

In step S112, the control unit 161 transmits a control signal to the mold front-rear travel device 165 to move the mold forward-backward traveling device 165 to move the movable mold 105, thereby moving the movable mold 105 away from the fixed mold 103. As a result, as shown in FIG. 24, a space is formed between the fixed mold 103 and the movable mold 105. Further, as is apparent from the drawing, as a result of the mold separation, the primary molded article 147 remains on the movable mold 105 side, and the secondary molded article 153 remains on the fixed mold 103 side.

In step S113, as shown in FIG. 25, the control unit 161 waits for a robot (not shown) to enter the space and take out the secondary molded article 153.

After the end of step S113, the flow returns to step S101.

(8) Structure and action of the fixture

The structure and operation of the jigs 133 (133a, 133b) will be described in detail with reference to Figs. 26 to 30. Fig. 26 is a plan view showing a state in which a jig holds a one-piece decorative sheet. Figure 27 is a plan view showing the state in which the jig is in the open position. Figure 28~ Fig. 30 is a schematic cross-sectional view showing a positional relationship between a one-piece decorative sheet and a pair of jigs during loading.

As shown in FIG. 26, the jig 133 is composed of a pair of first jigs 133a and a pair of second jigs 133b. The pair of first jigs 133a pressurize the left and right sides of the one-piece decorative sheet 141 in the drawing. Further, the pair of second jigs 133b pressurize the upper and lower sides of the one-piece decorative sheet 141 in the drawing. In more detail, each of the jigs 133a, 133b has a first portion 133A that abuts on each side of the one-piece decorative sheet 141 and a second portion that abuts on the outer side of each side of the first surface 129 of the second movable mold 115. 133B. Thus, each of the jigs 133a, 133b covers the outer edge of each side of the one-piece decorative sheet 141 to press the one-piece decorative sheet 141 against the second movable mold 115, so that the one-piece decorative sheet 141 can be improved relative to the second movable mold The positional accuracy of 115, which in turn improves the transfer accuracy in the subsequent molding and decoration.

As shown in Fig. 27, when the jig 133 is moved to the open position, the pair of first jigs 133a are moved obliquely outward from the nip position as described above. Thereby, when the one-piece decorative sheet 141 is carried into the second movable mold 115, the one-piece decorative sheet does not come into contact with the pair of first jigs 133a. As described above, when the one-piece decorative sheet 141 is carried in, the pair of first jigs 133a are located at an open position that is obliquely outward from the second movable mold 115 from the gripping position, so that the one-piece decorative sheet 141 is difficult to be A jig 133a is in contact. As a result, the one-piece decorative sheet 141 is hard to be deformed or damaged. In this case, the above-described effects can be obtained by any one of the above-described one-piece transfer sheet and the one-piece laminate sheet, and in particular, the one-piece transfer sheet has a small thickness and low rigidity, and thus can be obtained in the above case. Excellent results. As a result, even a thin sheet can be accurately aligned and wrinkle is difficult.

In addition, as shown in FIG. 27, a pair of second jigs 133b are from the clamping position Moving vertically relative to the first face 129. However, as shown in FIG. 28, the distance between the pair of second jigs 133b from the first face 129 is different from each other. Therefore, when the robot 131 is loaded into the one-piece decorative sheet 141, as shown in Fig. 28, initially, the one-piece decorative sheet 141 is in contact with the second jig 133b on one side, and then, as shown in Fig. 29, a one-piece decoration The sheet 141 is in contact with the second jig 133b on the other side, and finally, as shown in FIG. 30, the one-piece decorative sheet 141 abuts against the first surface 129. As described above, the number of the jig members in which the one-piece decorative sheet 141 is in one contact becomes small. Therefore, the resistance acting on the one-piece decorative sheet 141 is reduced every time, and as a result, the one-piece decorative sheet 141 is hard to be deformed or damaged.

The first clamp 133a is fixed to, for example, a rockable arm that is mounted to a clamp drive 175 (eg, a hydraulic cylinder). The second jig 133b is fixed to, for example, a rod (not shown), and the rod is attached to a jig driving device 175 (for example, a hydraulic cylinder). Here, the jig is not placed in the mold and can be carried by the robot arm from the outside to the inside of the mold.

According to the molding simultaneous decoration device 1, for example, a cover of a casing of a cellular phone in which a three-dimensional pattern is provided on the front and back surfaces and a fitting rib is provided on the back surface can be manufactured. The decoration of the front and back surfaces can be obtained by using a transparent material in the first resin portion 145, and further decorating the first resin portion 145 by the one-piece decorative sheet 141 and the long decorative sheet 123. The rib is formed by the second resin portion 151.
