Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier device for sequentially carrying members to be assembled to respective assembly work positions in an assembly line or the like.

[0002]

2. Description of the Related Art In a door manufacturing line of an automobile assembly line, as shown in FIG. 3 (a), a hanger (26) is mounted on a traveling body (25) which is guided by rails (not shown). And the hanger (26) supports the door frame (27), and the door frame (27) is intermittently transferred to each assembly work position. Since many of the parts to be assembled (trims, knobs, etc.) in this door line are interior parts, in order to facilitate the assembly of these parts, as shown in FIG.
The interior surface (27a) of the above is directed to the worker side, and the lower portion thereof is inclined to the worker side, that is, the interior surface (27a) is held so as to be an upward inclined surface when viewed from the operator side, and each work is performed. Transported to the position.

[0003]

By the way, not only the above-mentioned interior parts but also exterior parts such as glass are included in the assembly parts of the door line. This glass (29)
Since the hanger (26) interferes and cannot be installed from the outside of the door frame (27), a worker standing inside the door frame (27) usually works from above.
It is inserted in the gap between the door frame (27) and the door frame (27) so as to be installed in the opening (28) of the door frame (27).

However, in a vehicle with a high vehicle height, the height of the door is also increased accordingly, so that the distance between the upper end of the door frame (27) and the upper end of the hanger (26) and the traveling body (25) is narrow. Become. Therefore, it becomes difficult to insert the glass (29), workability is deteriorated, and further, the glass may come into contact with the hanger or the traveling body and be damaged. As shown in Fig. 3 (b), these problems are caused by the insertion opening (30) of the glass (29) being oriented in a substantially vertical direction, so that the upper end of the hanger (26) positioned directly above the insertion opening (30). The traveling body (25) is located on the insertion path of the glass (29) and obstructs the insertion work.

Therefore, it is an object of the present invention to facilitate the assembling work of glass on a door frame and prevent damage to the glass.

[0006]

In order to achieve the above object,
According to the present invention, the upper rail and the lower rail that are vertically separated from each other and extend in the transport direction, the traveling body that travels while being guided by the upper rail, and the traveling body can swing in the direction orthogonal to the transportation direction. And a hanger having a supporting portion for supporting the member to be assembled, and the lower part of the hanger is brought into contact with the lower rail to hold the hanger in a predetermined posture and convey it to each assembling work position. In this case, the lower rails at the predetermined assembly work position and the standby position set on the upstream side are removed, and a temporary pedestal capable of reciprocating parallel to the transport direction is provided on the side of the removed part. The cradle is driven synchronously with the traveling body from at least the standby position to the assembly work position, and a reciprocating drive source for reciprocating in the direction orthogonal to the transport direction is arranged on the temporary cradle. It was decided to reciprocate between the temporary receiving wearing the temporary receiving portion for supporting an object to be assembled member on the extension of the lower rail and its lateral position in the reciprocating driving source.

[0007]

When the hanger supporting the member to be assembled reaches the removed portion of the lower rail, the lower end of the hanger transfers to the temporary receiving portion which is standing by on the extension line of the lower rail. At the same time, the temporary receiving stand is activated to drive the temporary receiving portion synchronously in the same direction as the traveling body, and transfer the hanger and the assembly member to the assembly work position while maintaining the relative position between the temporary receiving portion and the traveling body. During this transfer, the reciprocating drive source on the temporary receiving table is activated, and the temporary receiving section is swung in the direction orthogonal to the transport direction and retracted to the side from the extension line of the lower rail. The assembled member supported by the hanger is swung to an inclined posture.

When the member to be assembled is moved to the assembling work position, the worker assembles the parts. At this time, since the member to be assembled is in the inclined posture, the component insertion port between the upper end of the member to be assembled and the upper end of the hanger is also inclined. As a result, the upper ends of the traveling body and the hanger retract out of the component insertion path, so that the worker can easily insert the exterior component into the gap between the member to be assembled and the hanger, and Can be avoided.

When the assembling of the parts is completed, the reciprocating drive source is activated in the opposite direction to return the temporary receiving portion to the extension line of the lower rail, and the traveling body is restarted to move the assembled member downward from the temporary receiving portion. Transfer to the rail. After that, the temporary receiving table is moved back to the standby position, and the same procedure is performed thereafter.

A hanger (4) is suspended from and supported on the lower part of each traveling body (3). This hanger (4) has a pivotal support (3a) provided below the traveling body (3).
In addition, it is pivotally supported so as to be swingable in a direction orthogonal to the transport direction (left-hand direction in the drawing). As shown in FIG. 2, a supporting portion (4a) is formed at the lower end of the hanger (4) by bending this portion toward the operator (front side in the drawing), and is placed on the hanger (4). The assembled member (5), for example, the door frame, is supported on the hanger (4) by this support portion (4a). (6) is a hanger (4)
Is a restraint member attached to the. This restraint member (6) is
The door frame (5) is configured to be expandable / contractible along the carrying direction, and holds the door frame (5) from both sides in the width direction to prevent the door frame (5) from falling off the hanger (4) due to an impact or the like.

Below each of the assembling work positions, a flat plate-shaped lower rail (7) is arranged in parallel with the upper rail (1). The lower rail (7) is in sliding contact with the lower end portion of the hanger (4) and guides the lower end portion to the worker side. The contact between the lower rail (7) and the hanger (4) causes the door frame. (5) is held in a tilted posture, that is, the interior surface (5a) is kept in a posture of a climbing slope when viewed from the operator side, whereby the assembling property of the interior parts is improved. A roller (not shown) is pivotally attached to a contact portion of the hanger (4) with the lower rail (7) so that the hanger (4) can smoothly slide on the lower rail (7). Is desirable.

Among the assembling work positions, the lower rail (7) is removed at the glass assembling work position (B) and the standby position (A) set upstream of the glass assembling work position. On the side of this removed portion, specifically, on the side of the exterior surface (5a) side of the door frame (5), a temporary pedestal (11) capable of reciprocating in parallel with the transport direction of the door frame (5).

When the hanger (4) supporting the door frame (5) reaches the removed portion of the lower rail (7),
The lower end of the hanger (4) transfers to the temporary receiving part (13) waiting at the waiting position (A) on the extension line of the lower rail (7). At the same time, a drive device (not shown) for the temporary receiving base (11) is activated, and the temporary receiving base (11) and the temporary receiving portion (13) are slid in the transport direction. The traveling speed of the temporary support table (13) at this time is made equal to the traveling speed of the traveling body (3).

While the temporary support (11) is moving, the air cylinder (1
When 2) is retracted, the temporary receiving portion (13) is pulled in a direction away from the operator, and the door hanger (4) swings about the pivot axis (O) in a direction orthogonal to the transport direction. As a result, the door frame (5) is in an inclined posture, and the exterior surface (5b), which is substantially vertical, becomes a downward inclined surface as seen from the operator, as shown by the two-point diagonal line in FIG.

The door frame (5) in such an inclined posture
Is transferred to the assembling work position (B), the traveling body (3) and the temporary pedestal (11) are stopped, and then the glass is assembled. At this time, the upper end opening of the gap between the door frame (5) and the hanger (4), that is, the insertion opening (C) of the glass (19) faces the worker side, and the traveling body (3a) and the hanger. The upper end of (4) is located outside the glass insertion path. Therefore, the operator should insert the glass (1
