Specifically, the panel 12 press-molded in the press step (press stage) 11 is transferred to the loading stage 13. In this example, the panel 12 is an outer plate of a vehicle side panel including an outer plate and an inner plate.

  On the other hand, the carrier 15 is intermittently conveyed by the overhead conveyor 14 (arrow (1)). At the loading stage 13, the panel transport hanger 30 is lowered to a predetermined position by an elevator 16 called a drop lift (arrow (2)). A driver 17 is placed near the predetermined position. The role of the driver 17 will be described later. This driver 17 is fixed to the foundation, building or equipment and does not move.

  A transfer robot 18 is disposed on the loading stage 13, and the transfer robot 18 transfers the panel 12 to the panel transport hanger 30 (arrow (3)). The transfer robot 18 returns to the standby position after depositing the panel 12 on the panel transport hanger 30.

  The panel transport hanger 30 in which the panel 12 is suspended is raised by the elevator 16 and connected to the carrier 15 (arrow (4)). The carrier 15 transports the panel transport hanger 30 together with the panel 12 to the welding process (welding stage) 19.

  Hereinafter, the structure of the panel conveyance hanger 30 will be described in detail. In the following description, “front and rear” is determined based on the vehicle front and rear of the vehicle panel, not the panel conveyance direction.

  As shown in FIG. 2, the panel transport hanger 30 includes a main body frame 31, an upper front support 32 extending from the main body frame 31, a lower front support 33 provided below the upper front support 32, and an upper front An upper rear support 34 that is provided rearwardly from the support 32, a lower rear support 35 provided below the upper rear support member 34, and a pin 37 and a lower portion of the support plate 36 that is lowered from the main body frame 31. The movable holding member 39 is provided via the lever 38, and the kick bar 41 is extended from the lever 38 in the opposite direction.

  The configuration of the main body frame 31 is arbitrary, but in this example, the rectangular frame 43, the cross frame 44 that reinforces the rectangular frame 43, and the lower side of the rectangular frame 43 are vertically lowered as shown in FIG. The first front lowering material 45, the second front lowering material 46, the central lowering material 47, the rear lowering material 48, the forward material 49 that horizontally connects the first front lowering material 45 to the central lowering material 47, and the central lowering material 47 ~ The rear material 51 that connects the rear descending material 48 horizontally.

  The lower front support body 33 extends from the first front lowering material 45 to the front, the upper front support body 32 extends from the second front lowering material 46, and the lower rear support body 35 extends from the central lowering material 47. Then, the upper rear support 34 is extended from the rear lowering member 48. Then, the support plate 36 is lowered from the forward material 49. A stopper pin 52 that defines the lower limit position of the lever 38 is provided on the support plate 36.

As shown in FIG. 4, the upper front support body 32 is a horizontally extending rod-like body (preferably a bar or a pipe), and a plurality of (six in this example) receiving seats 53 are attached to the upper surface at an equal pitch. ing. The receiving seat 53 is preferably an equilateral angle or an unequal angle. The operation of the receiving seat 53 will be described later.
An angle (angle steel) consists of two mutually perpendicular flanges. For convenience, in each angle, the flange on the second front lowering member 46 side is referred to as a back flange 54 and the other side is referred to as a front flange 55.

  The angle θ1 formed by the upper surface of the upper front support 32 and the front flange 55 and the angle θ2 formed by the upper surface of the upper front support 32 and the rear flange 54 may be the same, but in this example, θ1 < θ2 was set. In manufacturing, a round bar 56 is welded to the upper surface of the upper front support body 32, a front flange 55 is placed on the round bar 56, the receiving seat 53 is positioned, and the receiving seat 53 is easily placed on the upper front support body 32. Can be installed on.

As shown in FIG. 5, a lever 38 is attached to the support plate 36 via a pin 37, and a movable restraining member 39 and a kick bar 41 are attached to the tip of the lever 38. The movable restraining member 39 includes a metal core member 57 that functions as a weight, and a soft material 58 that covers the core member 57. The soft material 58 is preferably rubber or resin.
By covering with the soft material 58, the impact energy when the movable restraining member 39 is dropped is alleviated, and there is no concern that the bottom edge of the panel will be damaged.

  Further, preferably, a metal bush 59 is interposed between the support plate 36 and the pin 37. The metal bush 59 is preferably an oil-containing sintered body. Since the metal bush 59 serves as a bearing, the lever 38 can swing smoothly and wear can be prevented.

The operation of the panel transport hanger 30 having the above configuration will be described next.
As shown in FIG. 6A, the panel transport hanger 30 is lowered by the elevator 16. When further lowered, the kick bar 41 hits the driver 17.
Then, as shown in FIG. 6B, although the panel transport hanger 30 is lowered, the kick bar 41 is prevented from being lowered by the driver 17, and the movable restraining member 39 is held at a relatively raised position. In this state, the panel 12 is carried to the panel transport hanger 30 by the transfer robot (FIG. 1, reference numeral 18) as indicated by the arrow (3).

  As shown in FIG. 7A, since the movable restraining member 39 is held at an unobstructed position, the lower front support 33 and the movable restraining member 39 are passed through the front opening 61 and the lower opening is passed through the rear opening 62. The panel 12 is moved from the front side of the drawing to the back side through the rear support 35.

  7B, the panel 12 is laterally moved as indicated by the arrow (7) by the transfer robot (FIG. 1, reference numeral 18), and then the arrow ( It is lowered as shown in 8) and placed on the receiving seat 53. If the panel 12 is placed on the front flange 55, it slides down toward the valley 63 as indicated by an arrow (9). The same applies to the case where it is placed on the back flange 54. As a result, all the panels 12 are stored in the valley 63 of the receiving seat 53.

  The lower front support member 33 is a bar or pipe extending in the thickness direction of the panel 12 (left-right direction in the figure), and thus holds a plurality of panels 12 as shown in the figure. The same applies to the other supporting members. In this example, a maximum of six panels 12 can be held together.

  As shown in FIG. 7C, the panel transport hanger 30 is raised by the elevator 16. Then, the upper edge of the front opening 61 is suspended by the lower front support 33, and the upper edge of the rear opening 62 is suspended by the lower rear support 35. When the kick bar 41 is separated from the driver 17 due to the ascent, the movable restraining member 39 indicated by an imaginary line is gradually lowered by its own weight, and as a result is lowered to the position of the solid line to restrain the lower edge of the front opening 61. Since it is restrained by the movable restraining member 39, the panel 12 is transported by the panel transport hanger 30 without being inclined.

  As shown in the comparative example of FIG. 8A, if the panel 12 is suspended by the technique of Patent Document 1, the first and second positioning members 110 and 116 exhibit the action of sandwiching the center pillar 105. Mainly, the panel 12 is suspended by the support 108. That is, the support body 108 is supported at one point in the center. Depending on the rigidity of the panel 12, the front end and the rear end are lowered, and the center 12 is easily deformed.

In this regard, in the embodiment of FIG. 8B, the panel 12 is suspended by the lower front support 33 and the lower rear support 35 that are provided apart from each other, so that the panel 12 is supported at two points and is not easily deformed. Become.
Therefore, it can be said that the embodiment is a hanger suitable for the panel 12 that does not require special rigidity.

Next, the installation position of the movable restraining member 39 is examined.
As shown in FIG. 9A, the panel 12 in which the rear portion 12R largely protrudes backward with respect to the front portion 12F may be put to practical use.

  The overall center of gravity Ga is closer to the rear from the center than the midpoint between the lower front support 33 and the lower rear support 35. Since the slanted rear portion 12R is heavy, there is a concern that the panel 12 will rotate in the clockwise direction in the drawing around the lower rear support 35 when it receives acceleration force or impact during transportation.

  In this regard, in this embodiment, the movable restraining member 39 is positioned in front of the lower front support 33. The movable restraining member 39 urges the panel 12 to rotate in the counterclockwise direction around the lower front support 33. As a result, there is no possibility that the panel 12 rotates to the right in the figure.

  For the panel 12 whose overall center of gravity Gb is at an intermediate point (substantially intermediate point) between the lower front support 33 and the lower rear support 35, as shown in FIG. The member 39 may be disposed between the lower front support 33 and the lower rear support 35.

The usage of the lower front support 33 and the lower rear support 35 has been described above. Next, how to use the upper front support body 32 and the upper rear support body 34 will be described.
As shown in FIG. 10, the so-called minivan panel 12 is one size larger. For example, in addition to the front opening 61 and the rear opening 62, the panel 12 is provided with a small opening 64 having an opening area smaller than that of the rear opening 62 after the rear opening 62.

The upper front support 32 supports the upper edge of the front opening 61, the upper rear support 34 supports the upper edge of the small opening 64, and the movable restraining member 39 suppresses the lower edge of the front opening 61.
Since the front upper support 108 and the upper rear support 34 are sufficiently separated in the vehicle longitudinal direction, they are suitable for the panel 12 that is long in the longitudinal direction.

Next, a modified example of the movable holding member 39 will be described.
As shown in FIG. 11, a triangular bracket 65 is attached to the panel transport hanger 30, and a rail 66 is attached to the oblique side of the triangular bracket 65.
As shown in FIG. 12, which is a sectional view taken along the line 12-12 of FIG. 11, a slider 67 is fitted on the rail 66, and a steel ball 69 is interposed between the slider 67 and the rail 66. Then, the movable holding member 39 and the kick bar 41 are attached to the slider 67.

  In FIG. 11, the movable restraining member 39 can be moved from the solid line position to the imaginary line position by the cam driver 68. When the panel transport hanger 30 is raised, the movable restraining member 39 indicated by the imaginary line slides down to the position of the imaginary line by its own weight. The movable restraining member 39 can restrain the panel.

Next, a further modification of the movable restraining member 39 will be described.
As shown in FIG. 13A, a cam driver 74 composed of an ascending slope 71, an upper surface 72, and a descending slope 73 is fixed to a floor (building or facility) 75. A V-shaped lever 38 is swingably provided on the support plate 36 via a pin 37.

As shown in FIG. 13B, when the kick bar 41 comes into contact with the ascending slope 71, the V-shaped lever 38 starts to rotate in the clockwise direction.
As shown in FIG. 13C, while the kick bar 41 is in contact with the upper surface 72, the movable restraining member 39 is held at the standby position. While being held, the panel is placed on the panel transport hanger.
As shown in FIG. 13D, when the kick bar 41 reaches above the descending slope 73, the V-shaped lever 38 rotates counterclockwise in the figure. As a result, the panel can be urged by the movable restraining member 39.

  That is, as shown in FIG. 13A, the movable restraining member 39 is moved to the standby position by the cam driver 17 while the panel transport hanger 30 moves horizontally. Next, the weight is lowered to the restrained position by its own weight, and the panel 12 is urged.

  In addition, the panel conveyance hanger 30 of this invention should just be provided with the front support member, the back support member, and the movable suppression member, and it does not interfere with the structure shown in FIG.3, FIG.11 or FIG.13 suitably.

Moreover, the opening part provided in a panel may be one or more. The panel is not limited to a plate material, but may be an assembly that is face-to-face.
The present invention is suitable for a panel constituting a vehicle body, for example, an outer plate of a side panel.

  In addition, in the first and second aspects, the movable restraining member may be lowered by an actuator in addition to the one that falls by its own weight.

  The panel conveyance hanger of the present invention is suitable for a hanger that suspends and conveys a vehicle panel.

The receiving seat 53 is preferably an equilateral angle or an unequal angle. The operation of the receiving seat 53 will be described later.
An angle (angle steel) consists of two mutually perpendicular flanges. For convenience, in each angle, the flange on the second front lowering member 46 side is referred to as a back flange 54 and the other side is referred to as a front flange 55.

The angle θ1 formed by the upper surface of the upper front support member 32 and the front flange 55 and the angle θ2 formed by the upper surface of the upper front support member 32 and the rear flange 54 may be the same, but in this example, θ1 < θ2 was set. In manufacturing, a round bar 56 is welded to the upper surface of the upper front support member 32, a front flange 55 is placed on the round bar 56, the receiving seat 53 is positioned, and the receiving seat 53 can be easily moved to the upper front support member 32. Can be installed on.

As shown in FIG. 5, a lever 38 is attached to the support plate 36 via a pin 37, and a movable restraining member 39 and a kick bar 41 are attached to the tip of the lever 38. The movable restraining member 39 includes a metal core member 57 that serves as a weight, and a soft material 58 that covers the core member 57. The soft material 58 is preferably rubber or resin.
By covering with the soft material 58, the impact energy when the movable restraining member 39 is dropped is alleviated, and there is no concern that the bottom edge of the panel will be damaged.

As shown in FIG. 7A, since the movable restraining member 39 is held at an unobstructed position, the lower front support member 33 and the movable restraining member 39 are passed through the front opening 61 and the lower opening is passed through the rear opening 62. The panel 12 is moved from the front side of the drawing to the back side through the rear support member 35.

As shown in FIG. 7C, the panel transport hanger 30 is raised by the elevator 16. Then, the upper edge of the front opening 61 is suspended by the lower front support member 33, and the upper edge of the rear opening 62 is suspended by the lower rear support member 35. When the kick bar 41 is separated from the driver 17 due to the ascent, the movable restraining member 39 indicated by an imaginary line is gradually lowered by its own weight, and as a result is lowered to the position of the solid line to restrain the lower edge of the front opening 61. Since it is restrained by the movable restraining member 39, the panel 12 is transported by the panel transport hanger 30 without being inclined.

As shown in the comparative example of FIG. 8A, if the panel 12 is suspended by the technique of Patent Document 1, the first and second positioning members 110 and 116 exhibit the action of sandwiching the center pillar 105. Mainly, the panel 12 is suspended by the support member 108. That is, the support member 108 is supported at one point in the center. Depending on the rigidity of the panel 12, the front end and the rear end are lowered, and the center 12 is easily deformed.

In this regard, in the embodiment of FIG. 8B, the panel 12 is suspended by the lower-stage front support member 33 and the lower-stage rear support member 35 that are spaced apart from each other, so that the panel 12 is supported at two points and is not easily deformed. Become.
Therefore, it can be said that the embodiment is a hanger suitable for the panel 12 that does not require special rigidity.

The overall center of gravity Ga is closer to the rear from the center than the midpoint between the lower front support member 33 and the lower rear support member 35. Since the hatched rear portion 12R is heavy, there is a concern that the panel 12 may rotate in the clockwise direction in the drawing around the lower rear support member 35 when subjected to acceleration force or impact during transportation.

In this regard, in this embodiment, the movable restraining member 39 is positioned in front of the lower front support member 33. The movable restraining member 39 urges the panel 12 to rotate in the counterclockwise direction about the lower front support member 33. As a result, there is no possibility that the panel 12 rotates to the right in the figure.

The overall center of gravity Gb is, for the panel 12 such that the midpoint of the lower front support member 33 and the lower rear support member 35 (approximately midpoint), as shown in FIG. 9 (b), suppressing movable The member 39 may be disposed between the lower front support member 33 and the lower rear support member 35.

The usage of the lower front support member 33 and the lower rear support member 35 has been described above. Next, how to use the upper front support member 32 and the upper rear support member 34 will be described.
As shown in FIG. 10, the so-called minivan panel 12 is one size larger. For example, in addition to the front opening 61 and the rear opening 62, the panel 12 is provided with a small opening 64 having an opening area smaller than that of the rear opening 62 after the rear opening 62.

The upper front support member 32 supports the upper edge of the front opening 61, the upper rear support member 34 supports the upper edge of the small opening 64, and the movable restraining member 39 suppresses the lower edge of the front opening 61.
Since the upper front support member 32 and the upper rear support member 34 are sufficiently separated in the vehicle longitudinal direction, they are suitable for the panel 12 that is long in the longitudinal direction.

In FIG. 11, the movable restraining member 39 can be moved from the solid line position to the imaginary line position by the cam driver 68. When the panel transport hanger 30 is raised, the movable restraining member 39 indicated by an imaginary line slides down to the position indicated by the solid line by its own weight. The movable restraining member 39 can restrain the panel.

That is, as shown in FIG. 13A, the movable restraining member 39 is moved to the standby position by the cam driver 74 while the panel transport hanger 30 moves horizontally. Next, the weight is lowered to the restrained position by its own weight, and the panel 12 is urged.
