Description

[Detailed Description of the Invention] This invention relates to a tilting banger device for a transfer device suitable for assembling automobiles and the like on a transfer line, and more particularly to a banger opening/closing device for automatically opening and closing a banger at a loading/unloading section for transferred objects.

Conventionally, when assembling an automobile body while being suspended and transferred to a banger of an overhead conveyor provided along an assembly line, a tilting banger is used to facilitate assembly of the lower part of the body.

In this case, in order to open and close the banger laterally at the transfer object loading position, conventionally, a lever that projects laterally is attached to the banger, and the lever is operated to open and close the banger.

However, in a transfer line where the banger is not tilted, a steady rest rail is usually provided to prevent the transferred object from rolling, and a guide roller that projects laterally from the banger support member is guided by this rail. It had the disadvantage that it was difficult to operate because it was close to the steady rest rail.

The object of the present invention is to propose a tilting banger device for a transfer device that eliminates the above-mentioned drawbacks of the conventional device by omitting the lever by automatically opening and closing the banger using a banger tilting device.

An illustrated embodiment of the present invention will be described below.

In the figure, 1 is a drive chain of the overhead conveyor, 2 is its guide rail, and 3 is a carrier traveling rail provided below the conveyor. Among the four carriers 4a, 4bt 4C94d that travel on the rail 3, the carrier 4a is
, 4b, 4c, and 4d are connected to each other by a rod 5 so as to be flexible, and the carriers 4b and 4c are connected to each other by a load par 6 so as to be horizontally rotatable to form a transfer body 7, and the leading carrier 4a is connected to the drive chain 1. Tow it in the direction of the arrow.

The roller 8 that is pivotally supported at both ends of the load par 6 is fixed to a fixed guide 9.
This prevents the road par 6 from swinging sideways.

Front and rear vertical support rods 10 fixed to the load par 6 are connected by a vertical member 11, and a tilting frame 12 is suspended from the support rods 10.

The tilting frame 12 is formed by connecting the lower portions of a pair of front and rear angled horizontal members 13 with a vertical member 14, and a support rod 10 is arranged between the supporting piece 15 fixed to the inner center of each horizontal member 13 and the horizontal member 13. The lower part is inserted and pivotally attached with a pin 16 so as to be tiltable.

The inner ends of the two pairs of front and rear opening/closing arms 17 are pivotally attached to the inside of the horizontal member 13 on both sides of the pin 16 using pins 18, and the front and rear opening/closing arms 17 on both sides are respectively connected by vertical members 19 to form the opening/closing frame 20. The upper end of the banger rod 21 is fixed to the front and rear outer ends of the frame 20.

The banger rod 21 has front and rear parallel vertical parts 22 and 23 that are vertical in use, and receiving parts 24 that protrude inward from the lower ends of these parts, and the vehicle body S is supported by the receiving parts 24 on both the front and rear sides. do.

25 is a reinforcing plate for fixing the banger rod 21.

A stopper 26 having an adjustment screw is provided on the front horizontal member 13 and is brought into contact with the lower side of the opening/closing arm 17, whereby the vertical member 2
2 is prevented from tilting inward from a position at right angles to the transverse member 13.

A support member 27 extending outward from the opening/closing arm 17 is fixed to the front part of the front horizontal member 13, and a guide roller 29 is pivotally supported by brackets 28 fixed to both ends of the support member 27, and a steady rest is provided along the transfer path. The rollers 29 are guided by the rails 30 to prevent the vehicle body S from lateral shaking during transportation.

A support fitting 32 is fixed to a frame 31 that projects diagonally upward from the center of each vertical member 19 on both sides, and a round grooved cam roller 33 is pivotally supported on this.

The axis of the cam roller 33 is in the direction supporting the axis of the pin 16.

In the work area where the vehicle body S is tilted, the steady rest rail 30 is omitted, and the tilting cam 34 in contact with the upper side of the cam roller 33 is fixed to a fixed member across the front and rear of the area, and the height of the tilting cam 33 is adjusted. is configured to face the transfer direction and gradually decrease to a predetermined height along a cylindrical surface centered on the pin 16, and the guide 9 prevents the load par 6 from tilting.

As a result, the cam roller 33 is pushed down as it moves, and the tilting frame 12 and banger rod 21 are tilted while supporting the vehicle body S (position shown by the dashed line in FIG. 3).

At the loading/unloading part of the vehicle body S, an opening/closing cam 35 is provided that contacts the lower side of the cam roller 33, and similarly to the tilting cam 34, the cam roller 33 is pushed up as it moves, and the banger rod 2
1 to the side (position shown by the two-dot chain line in Figure 3).

In this case, since the tilting frame 12 is rested by the guide roller 29, the opening/closing position of the banger rod 21 is determined only by the height of the opening/closing cam 35, and accurate and stable opening/closing operations are performed.

The present invention has the above-mentioned configuration, and not only is the banger opening/closing operation stable, but it can also be tilted to the left or right while suspending objects such as the vehicle body, and the cam roller for tilting can also be used for opening/closing the banger rod. This has the effect of reducing equipment costs.
