Description

[Detailed Description of the Invention] The present invention relates to a reversing device for reversing the orientation of an object such as a press-molded part.

For example, when automatically piling (loading) molded parts formed by a press machine, the molded parts conveyed by a conveyor need to be oriented in a predetermined orientation and then piled.

In view of the above points, the present invention is designed to hold an object by a holding device provided at the tip of an arm, and by rotating this arm, the object is reversed and the object is oriented in a predetermined direction. When reversal is not necessary, the holding device is rotated in the opposite direction to the rotation of the arm by an angle equal to the rotation angle of the arm, so that the same result as if the object had not rotated is obtained.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, 1 is an accumulation conveyor, and objects such as molded parts are conveyed by this accumulation conveyor.

The object once hits the stopper 2 and its posture in the front-back direction is corrected.

After the stopper 2 descends, the object is placed on the timing conveyor 3.

At this time, the object is stopped by the first alignment hook 4, and its left and right positions are adjusted by the width alignment conveyors 5 and 6, which proceed in opposite directions from both sides of the timing conveyor 3.

Then, when the width aligning conveyors 5, 6 and the first alignment hook 4 move backward, the object hits the second alignment hook 7 and stops.

Reference numerals 8 and 9 are swing arms that are installed on both sides of the timing conveyor 3, and one end is attached to a rotating shaft 11, 12 that is provided in a direction perpendicular to the moving path of the object. It rotates along with the rotations of 11 and 12.

Further, at the other ends of the switching arms 8 and 9, object holding members 13 and 14 (
An example of an object holding device) is provided.

Note that the object holding device may be a device such as a clamp device.

The rotating shaft 11.12 is rotated by a drive shaft 15.16 via a gear, and at this time the swing arms 8, 9 also rotate together around this rotating shaft 11.12.

The clamping members 13, 14 are then advanced in opposite directions to clamp the object.

Next, the swing arm 8 is rotated by rotating the rotating shafts 11 and 12.
, 9 by 180°, the clamping members 13.14 come to positions X and Y indicated by chain lines, and the object rotates by the rotation angle of the swing arm 8.9, reversing its posture.

Figure 3 shows the object E as the swing arms 8 and 9 rotate.
This figure shows how the posture of the person changes one after another.

When the clamping members 8 and 9 are retracted together at the positions X and Y, the objects are placed on the stacking conveyor 17.

When the rotating shafts 11 and 12 rotate in the opposite direction, the swing arms 8 and 9 return to their original positions.

By repeating the above operations, the stacking conveyor 17
Objects are stacked one after another on top.

Since the stacking conveyor 17 can be lowered gradually, the stacking position can always be kept constant by lowering the stacking conveyor 17 according to the stacking height of the objects.

After the object stacked at a predetermined height is transferred to the chuck conveyor 18, the lifting rod 19 is lowered, the object is gripped by the chuck 20, the lifting rod 19 is raised, and then moved along the traveling beam 22 and turned. The lifting rod 19 is again lowered onto the pallet 25 supported by the fork 24 attached to the table 23, and the stacked objects are placed thereon.

26 is a conveyor frame, and 27 is an arm drive frame.

Further, 28 and 29 are columns, and 30 is a table lifter.

Next, a case where the object does not need to be inverted will be explained.

A drive shaft 32.33 is provided concentrically through the axis of the rotating shaft 11.12, with a clutch 34.35 interposed therebetween;
This drive shaft 32.33 and the support shaft 36 of the clamping member 13.14
．． 37 is provided with sprockets 38.39 and 40.41, and a drive shaft 32.33 and a support shaft 36.37 are connected by a chain 42.43.

Therefore, by engaging the clutches 34 and 35, the holding members 13 and 14 can be rotated.

Therefore, when the holding members 13.14 are rotated by the rotational force of the drive shafts 32 and 33 by the same rotation angle in the opposite direction to the rotation of the swing arms 8 and 9, the object will not rotate at all and will maintain its starting position.

FIG. 4 shows the attitude of the object E at this time.

Note that even if the rotation of the clamping members 13 and 14 is temporarily applied at the same rotation angle (180') as the rotation angle of the swing arms 8 and 9, for example, at a position where the swing arms 8 and 9 are rotated by 90 degrees, the same result will be obtained. is obtained.

As is clear from the above explanation, according to the present invention, if the clutch of the drive device is disengaged, the holding device that holds the object will not rotate relative to the swing arm, so when the swing arm rotates, the object will be reversed. Furthermore, when the clutch is connected, the holding device rotates at a rotation angle equal to the rotation angle of the swing arm, but in the opposite direction, so that objects can be handled without being turned over.
