[Action]

The distribution chute distributes and supplies articles to the left and right lifting buckets by a distribution damper that rotates left and right around a vertical axis.

The chute moves up and down in conjunction with the rolling device by connecting with the cam plate forming the rolling device.

When the article is supplied to either the left or right lifting bucket via the sorting chute by the belt conveyor, the sorting damper of the sorting chute continuously supplies the article to the other lifting bucket, and during that time. In addition, the lifting bucket previously supplied is lifted by the lifting device.

The cam roll of the ascending / descending bucket is engaged with the cam groove provided in the cam plate of the rolling device set at an arbitrary height, and the elevator bucket rolls around the fulcrum pin. Then, the articles in the lifting bucket are discharged into the chute.Next, the lifting bucket descends and stands by in the original state of being supplied from the sorting chute, and the articles in the other lifting bucket are stored. When the supply is completed, the same operation as above is performed.

This operation is repeated continuously.

When a certain amount of articles are supplied from the receiving port into the hopper by the chute, the chain motor of the chain lifting device is actuated, which causes the screw shaft to rotate and the slider screwed onto the screw shaft and the side surface of the slider. The moving chain wheel attached to the vehicle moves from the position shown by the solid line in FIGS. 1 and 3 to the position shown by the phantom line.

As a result, the movable chain wheel and the chain wound around the chain wheel are lowered, and the hopper suspending tool and the hopper suspended at the tip of the chain move in the storage container according to their weights as shown in FIG. It descends as shown by the phantom line.

Then, the distance sensor detects the distance to the bottom of the storage container and thereafter to the article, and stops the operation of the chain motor of the chain lifting device at a height at which the article is not damaged even if the article is discharged.

At the same time, the piston of the air cylinder is actuated to lower the fixing rod and the cone lid as shown by the phantom line in FIG. 1, thereby opening the discharge hole of the hopper and dropping the article into the storage container. To be crowded.

When the work of dropping the articles is completed, the piston of the air cylinder raises the fixing rod and the cone lid to the original position, and at the same time, the chain motor of the chain lifting device operates to reversely rotate the screw shaft. The slider threadedly mounted on the screw shaft and the movable chain wheel attached to the side surface of the slider move from the position shown by the phantom line in FIGS. 1 and 3 to the original position shown by the solid line. .

As a result, the chain that is wound around the moving chain wheel and chain wheel is pulled and rises,
The hopper suspending tool and the hopper suspended from the chain are raised to the original position as shown by the solid line in FIG.

If the fixing rod is connected to the piston of the air cylinder so that it can expand and contract, the height of the distance sensor is adjusted to adjust the height at which the article is dropped and discharged.

Next, when the slide motor of the arm advancing / retreating device is operated, the screw shaft is rotated and the screw shaft is screwed into the fixing nut attached to the disk.
The position moves from the position shown by the solid line in FIGS. 1 and 3 to the position shown by the virtual line.

Then, when the slide motor is actuated to rotate the screw shaft in the reverse direction, the arm moves from the position shown by the phantom line in FIGS. 1 and 3 to the original position shown by the solid line. .

By these, the hopper suspension and the hopper suspended by the chain are moved to the front and the rear of the position of the original arm.

Finally, when the angle motor of the arm rotation device is activated,
Since the disk rotates about the disk axis, the arm mounted on the disk moves from the position shown by the solid line in FIG. 3 to the position shown by the phantom line.

When the angle motor is actuated and the disk is rotated in the reverse direction, the arm moves from the position shown by the phantom line in FIG. 3 to the original position shown by the solid line.

By these, the hopper suspension and the hopper suspended by the chain are moved to the left and right (rotational direction) of the position of the original arm.
