Description

  The present invention relates to a handle winding device for a leather-wrapped vehicle. More specifically, the present invention relates to a handle winding device for a leather-wound vehicle, which takes, by hot air, wrinkles generated when an operation wheel supported by a spoke portion is covered with leather.

  In recent years, the exterior of a vehicle handle has been improved by covering the surface of the vehicle handle with leather such as cowhide from the viewpoint of improving the handle operability with a good grip feeling and improving the design by obtaining a high-grade appearance. Has been done. A vehicle handle formed from an annular wheel portion and a plurality of spoke portions that support the wheel portion is formed by expanding the leather formed in an annular shape to the outer peripheral portion of the wheel portion, and then the outer diameter of the wheel portion. After wrapping toward the inner diameter, applying adhesive and pasting together, sew both edges of the leather to be joined at the inner diameter part, and the spoke part is also bonded with the leather that is continuous with the wheel part. It is formed by sewing following the part. The leather-wrapped vehicle handle formed in this way tends to generate wrinkles on the leather because the leather is wrapped around the outer periphery of the wheel while the leather is covered and sewn on the handle. The R shape formed at the spoke base end portion, which is the connecting portion of the spoke portion, is a portion where wrinkles are particularly likely to occur. Therefore, in order to obtain a good appearance and feel, a scoring operation using hot air has been performed as a finishing process. Such leather wrinkling utilizing the heat shrinking action of leather is disclosed in Patent Document 1, for example.

A motor 68 is attached to the other end of the shaft 60, and the shaft 60 is rotatably supported on the support column 52 by the motor 68. The shaft 60 is linked to the connecting portion 50 and the holder 46 described above, and the connecting portion 50 and the holder 46 are also rotated as the shaft 60 rotates. Further, the support column 52 is attached to the upper portion of the table 54, and the table 54 moves along the two rails 56 in the handle attachment moving device 40.

  The other end portion of the shaft 60 to which the holder 46, the support portion 48, and the connecting portion 50 are attached serves as a position detection rotating body 12 i for detecting the spoke base end portion 17 of the operation wheel 12 in the handle box device 30. It becomes the structure which supports. The position detection rotating body 12i is supported in the same configuration as the configuration in which the operation wheel 12 is supported by the support column 52, and the holder 46i, the support portion 48i, and the connecting portion 50i that support the position detection rotating body 12i are attached. Thus, the operation wheel 12 and the position detection rotating body 12i can rotate synchronously on the same axis.

The position detection rotator 12i can be used as the position detection rotator 12i having the same configuration as the operation wheel 12, that is, the same configuration as the operation wheel 12 covered with leather for removing wrinkles. Therefore, even if the operation wheel has a different number of spoke parts, it is possible to detect the position state in which the spoke part is connected to various operation wheels without complicated adjustment. Therefore, the versatility of the device is very high. At that time, spacers are provided on the support portions 48 and 48i that are in contact with the spoke portions 16 and 16i to support the operation wheels 12 and 12i, and the space between the spoke portions 16 and 16i and the support portions 48 and 48i is appropriately set. By adjusting, it becomes possible to support various types of operation wheels 12 and 12i.
The handle mounting / moving device 40 is shut off from the outside by a safety box 42, and the holders 46, 46 i, the support portions 48, 48 i, and the connection portions 50, 50 i protrude from the openings 44, 44 i of the safety box 42. Thus, the operation wheel 12 and the position detection rotating body 12i are mounted outside the safety box 42. Further, the position detection rotator 12i is housed in the position detection rotator box 80, and the position detection rotator 12i is moved through the position detection rotator box 80 as the operation wheel 12 is moved to the handle box device 30. Move in the direction.

  The position detection rotating body box 80 is attached with a laser sensor 74 and a reflecting plate 75 facing each other on the side surface. The laser sensor 74 and the reflecting plate 75 are attached to both side surfaces of the position detection rotating body box 80 with the position detection rotating body 12i sandwiched therebetween, and the spoke base end portions 17i of the position detection rotating body 12i are connected to the laser sensor 74 and By detecting with the reflector 75, the position of the spoke base end portion 17 of the operation wheel 12 that rotates in synchronization with the position detection rotating body 12i can be adjusted. Further, as shown in FIGS. 5 and 6, the laser sensor 74 and the reflection plate 75 are disposed at a position corresponding to the outlet 34 of the handle box device 30 in the position detection rotating body box 80. By detecting the spoke base end portion 17 i of the detection rotating body 12 i in the position detection rotary body box 80, the spoke base end portion 17 of the operation wheel 12 can be aligned with the vicinity of the outlet 34 of the handle box device 30.

  Next, a method for removing wrinkles generated when the operation wheel 12 is covered with the leather 14 will be described. First, as shown in FIG. 5, the center hole 19 of the operation wheel 12 is fitted into the holder 46 of the handle mounting movement device 40, and the stopper 47 is engaged with the holder 46 portion protruding from the center hole 19. 12 is fixed to the column 52. Similarly, in the position detection rotating body box 80, the position detection rotating body 12i is fitted into the holder 46i, and the stopper 47i is engaged with the holder 46i protruding from the center hole 19i, as shown in FIG. As shown, the position detection rotor 12 i is fixed to the shaft 60. When the activation switch 94 is activated, the support column 52 to which the operation wheel 12 is attached moves along the two rails 56 toward the handle box device 30 side. At this time, the position detection rotating body 12i attached coaxially via the operation wheel 12 and the shaft 60 also moves in the position detection rotation body box 80 in the same direction as the operation wheel 12. As shown in FIG. 6, when a part including the spoke base end portion 17 of the operation wheel 12 reaches the handle box device 30, the motor 68 is activated and the shaft 60 starts to rotate in a certain direction.

When the operation wheel 12 reaches the handle box device 30, the hot air sent from the two hot air generators 20 passes through the duct 28 and is handled from the two air outlets 34 provided on both side surfaces of the handle box device 30. It is blown into the box device 30. Since the air outlet 34 is formed at a symmetrical position on both side surfaces of the rotation locus of the operation wheel 12 inserted from the handle insertion portion 36, hot air can be directly blown toward both side surfaces of the operation wheel 12.
The hot air supplied from the hot air generator 20 may be at a temperature at which the leather wrinkles covering the operation wheel 12 can be removed, and is preferably in the range of 250 ° C to 280 ° C. If the temperature of the hot air is lower than 250 ° C., leather wrinkles cannot be removed sufficiently, and much time is spent on the wrinkle removal work. Moreover, if the temperature of the hot air exceeds 280 ° C., the leather 14 may be excessively stretched or the leather 14 may be burnt.
Moreover, since the hot air generator 20 is equipped with the tank 22 which hold | maintains water and can generate | occur | produce the hot air containing a vapor | steam, a leather wrinkle can be removed effectively.

  The rotation speed of the operation wheel 12 in the handle box device 30 can be adjusted by the laser sensor 74 and the reflection plate 75. As shown in FIGS. 8 and 9, the position detection rotator 12i having the same form as the position detection rotator 12i is rotated after moving to the handle box device 30 side, and the spoke base end portion 17i of the position detection rotator 12i is rotated. When positioned between the laser sensor 74 and the reflecting plate 75, the position of the spoke base end 17 of the operation wheel 12 can be adjusted in the handle box device 30 at the same time. Further, since the laser sensor 74 and the reflection plate 75 are disposed in the position detection rotary body box 80 at a position corresponding to the outlet 34 of the handle box device 30, the spoke base end portion 17i of the position detection rotary body 12i is disposed. By detecting, the spoke base end portion 17 of the operation wheel 12 that rotates in synchronization with the position detection rotating body 12 i can be aligned with the vicinity of the outlet 34 of the handle box device 30. When the operation wheel 12 rotates and the spoke base end portion 17 of the operation wheel 12 reaches the vicinity of the blowout port 34, the rotation speed of the operation wheel 12 decreases, and the spoke base end portion 17 moves away from the vicinity of the blowout port 34. The rotation speed of the operation wheel 12 is controlled to be faster than when the spoke base end portion 17 is in the vicinity of the air outlet 34. Since the rotation speed of the operation wheel 12 becomes slow when the spoke base end portion 17 approaches the air outlet 34, the time for hot air to be blown to the spoke base end portion 17 increases, so the R portion of the spoke base end portion 17 It is possible to reliably remove the leather folds formed on. When only the wheel portion 18 of the operation wheel 12 is in the vicinity of the air outlet 34, the rotational speed of the operation wheel 12 is faster than when the spoke base end portion 17 is in the vicinity of the air outlet 34. While the surface of the leather 14 covered with the wheel portion 18 is prepared, the leather can be scraped efficiently.

  The attachment position of the laser sensor 74 and the reflection plate 75 may be provided before the position detection rotating body 12i in the rotational direction from the position corresponding to the air outlet 34 in the handle box device 30. After the spoke base end portion 17i of the position detection rotating body 12i is detected by the laser sensor 74 and the reflection plate 75, the rotation speed of the shaft 60 connected to the operation wheel 12 and the position detection rotating body 12i is slightly reduced. Therefore, there is a time difference between the detection of the spoke base end portion 17i and the timing at which the rotation speed of the operation wheel 12 is decreased. For this reason, the time difference between the mounting position of the laser sensor 74 and the reflecting plate 75 is provided in front of the position corresponding to the air outlet 34 in the handle box device 30 in the rotational direction of the position detection rotating body 12i to interfere with the operation wheel. When the twelve spoke base end portions 17 reach the vicinity of the hot air outlet 34 of the handle box device 30, the rotational speed can be slowed down in a timely manner.

  When the operation wheel 12 rotates once in the handle box device 30 and hot air is blown over the entire leather 14 covered with the operation wheel 12, the support column 52 to which the operation wheel 12 is attached extends along the rail 56. Move from 30 to the original position. At this time, the position detection rotating body 12i attached on the same axis as the operation wheel 12 also moves in the same direction as the operation wheel 12. Then, the stopper 47 attached to the holder 46 that supports the operation wheel 12 is removed, and the operation wheel 12 is removed from the holder 46.

  According to the leather vehicle handle scraping device of the embodiment described above, the position of the spoke base end portion 17 of the operation wheel 12 can be adjusted in the handle box device 30 by the laser sensor 74 and the reflection plate 75. Even if the operation wheel 12 has a different number of spoke portions 16, it can be easily applied to various operation wheels 12 without performing complicated adjustments, and the versatility of the device is very high.

The present invention is not limited to the above-described embodiment, and various other embodiments can be considered without departing from the gist of the present invention.
The leather 14 covered with the operation wheel 12 is not limited to natural leather such as cow leather, and may be synthetic leather or the like, and the outer surface of the leather 14 is subjected to processing for improving design such as embossing. It may be. Moreover, the temperature of the hot air that removes wrinkles generated in the leather can be appropriately adjusted depending on the state of the leather, such as the type and thickness of the leather.
Two hot-air generators 20 are not necessarily provided, and the outlet 34 may be provided only on one side surface of the handle box device 30. In addition, it is possible to provide two ducts in one hot-air generator 20 and to provide air outlets 34 on both side surfaces of the handle box device 30.
Further, the laser sensor 74 used as a detection body of the spoke base end portion 17i may be an infrared sensor or other various sensors. Further, the positions of the laser sensor 74 and the reflection plate 75 may be configured to detect the position detection rotating body 12i at a position other than the position corresponding to the air outlet 34 of the handle box device 30. Further, the spoke base end portion 17 of the operation wheel 12 may be directly detected by the laser sensor 74 without providing the position detection rotating body 12i.
