DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transporting a long workpiece (transport) in a lateral direction by using a plurality of transport means such as belt conveyors arranged in parallel. The present invention relates to a transferred object aligning device for aligning the posture of a transferred object (work).

[0002]

2. Description of the Related Art Conventionally, when a long aluminum profile is laterally transported in a lateral direction by using a plurality of belt conveyors arranged in parallel, the belt conveyor is mechanically synchronized by a line shaft. However, the attitude of the aluminum profile changes during the horizontal transfer due to thermal deformation of the aluminum profile or poor alignment of the belt, and the processing in the next process may become difficult. For example, in the cooling table of the equipment behind the extrusion press, aluminum profiles cut to a length of 50 to 60 meters are cooled while being fed sideways in the lateral direction. The posture of the profile may change, making it difficult for the stretcher to grip the end of the aluminum profile.

[0003] In this case, the operator raises and aligns the aluminum profile, or aligns the aluminum profile by temporarily preventing lateral movement of the aluminum profile by a stopper. In the case of, it is necessary to constantly monitor by the operator, and in the latter case, the surface of the aluminum profile is scraped by the belt conveyor or the aluminum profile itself is deformed while the transfer is blocked by the stopper New problems such as occur. On the other hand, the same trouble may occur during the horizontal transfer to the loading position after cutting the aluminum shape into a predetermined size. For this reason, at the time of loading, the aluminum profiles may come into contact with each other and be damaged.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object the following:
When a long transported object (work) such as an aluminum profile is horizontally transported using a large number of belt conveyors or other transport means,
It is an object of the present invention to provide a transferred object aligning apparatus capable of aligning transferred objects (work) without scraping or deforming the transferred object (work).

[0005]

According to a first aspect of the present invention, there is provided an apparatus for aligning an object to be transported.
A conveyed object aligning device that horizontally transfers a long conveyed object in a lateral direction of the conveyed object by using a plurality of transfer means arranged in parallel, wherein the conveyed object is arranged right beside the transfer means. Each of the sensors to be detected is arranged in a horizontal line, and a lifter is provided on the downstream side of the sensor, which receives the signal of the sensor and individually ascends, and simultaneously descends by the command of the control device receiving the signal of the sensor. Each is characterized by being arranged in a horizontal line.

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a cooling table 1 of a rear equipment of an extrusion press as an apparatus for aligning articles to be conveyed is provided with a number of belt conveyors 2 arranged in parallel. Each of these belt conveyors 2
It is supported by a driving pulley 3 and a driven pulley 4. The drive pulleys 3 are each fixed to a common line shaft 5 and rotate simultaneously.

On the other hand, right next to the belt conveyor 2, sensors 6 (not shown) for detecting an aluminum material are arranged so as to be in a horizontal line. Further, the lifters 7 are arranged on the downstream side of the sensor 6 so as to be in a horizontal line. As shown in FIG. 2, the lifter 7 is fixed to a shaft 8 parallel to the line shaft 5, and rotates between a position indicated by a solid line and a position indicated by a two-dot chain line. The rotation of the lifter 7 is performed by a lifter rotation device 10. The lifter rotating device 10 mainly includes an air cylinder 11, a rack 12, and a pinion 13. The rack 12 is fixed to a piston shaft 14 of the air cylinder 11, and the pinion 1 is fixed to a shaft 8 of a lifter 7.

Accordingly, when the rack 12 moves in the direction of the arrow a, the lifter 7 rises as shown by the solid line, and the head 9 of the lifter projects above the belt conveyor 2, and
When the rack 12 returns in the direction of the arrow b, the lifter 7 returns to the initial position as shown by a two-dot chain line and retreats below the belt conveyor 2. The head 9 of the lifter is formed so as to be substantially horizontal when raised, in order to lift a long conveyed object (aluminum material) during the lateral transfer by the belt conveyor 2.

In FIG. 2, reference numeral 20 denotes a control device. When a detection signal of an aluminum material is input from the sensor 6 to the control device 20, the control device 20 corresponds to the sensor 6 that has issued the detection signal. A command signal is issued to each of the controllers 21, and a switching valve 17 provided in the middle of the pipes 15 and 16 connected to the air cylinder 11.
Is switched in the direction of arrow c, and the lifter 7 corresponding to the sensor 6 that has issued the detection signal rises as described above. Then, when the first proximity switch 19 installed at a position facing each lifter 7 detects that the lifter 7 has risen, the signal is fed back to the control device 20 and the switching valve 17 is locked at the initial position.

As described above, the detection signals of the first proximity switches 19 are respectively stored in the control device 20, and when the detection signals of all the first proximity switches 19 are input to the control device 20, the control device 20 From the controller 22 to switch the switching valve 17 simultaneously in the direction of arrow d. And all lifters 7
Is returned to the initial position and detected by the second proximity switch 23, the signal is fed back to the control device 20, and the switching valve 17 is locked at the initial position. Here, the distance between the sensor 6 and the lifter 7 is set to a distance at which the aluminum members detected by the sensor 6 can be lifted by the corresponding lifters 7 in consideration of the transport speed of the belt conveyor 2 and the like. Reference numeral 18 indicates a stopper installed near the first proximity switch 19.

Next, the operation of the cooling table will be described. As shown in FIG. 3, when the aluminum profile A whose posture has changed flows, the leading portion of the aluminum profile A,
That is, the right portion of the aluminum material A is sequentially sensed by the first and second sensors 6a and 6b. Then, as shown in FIGS. 4 and 5, the first and second lifters 7a and 7b lift the belt from the belt conveyors 2a and 2b, and stop there.

The delayed portion of the aluminum profile A, that is, the portion on the left side of the aluminum profile A is used as it is on the belt conveyor 2.
When the third sensor 6c senses the central portion of the aluminum profile A, the third lifter 7c operates and the aluminum profile A
Is lifted from the belt conveyor 2c (see FIG. 6). The left side portion of the aluminum section A continues to move forward on the belt conveyors 2d and 2e as it is,
Aluminum profile A by the fourth and fifth sensors 6d and 6e
Is sensed, the fourth and fifth lifters 7d and 7e operate, the left end of the aluminum profile A is lifted from the belt conveyors 2d and 2e, and the aluminum profile A is aligned over the entire length. I do. That is, the aluminum profile A is parallel to the line shaft 5 (see FIG. 7).
