DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for releasing a profile from a carrier bar for film treatment and transport in a vertical hanging surface treatment process of a long aluminum sash.

[0002]

2. Description of the Related Art In the vertical hanging surface treatment process of a long aluminum sash hollow profile, in addition to pretreatment, anodic oxidation, electrolytic coloring, hot water washing, etc., surface treatment such as various kinds of coating according to coating specifications is performed. These are sequentially transported by a transporter in a processing tank in which the shaped members gripped by the carrier bar are sequentially transported,
Generally, it is processed by a program method.

As shown in the plan view of FIG. 4, a plurality of processed profiles (1) are horizontally arranged while being gripped by the profile gripper (4) of the carrier bar (3). The profile (1) is released (removed) from the profile gripper (4), and is conveyed by the belt conveyor (7).

[0004] Conventionally, the release of this profile is shown in FIG.
(C). That is, FIG.
As shown in (a), the profile (1) gripped by the carrier bar (3) is first placed on a profile receiver (8), and then as shown in FIG. The chuck (6) is pushed up in the direction of the arrow to separate from the profile,
Further, as shown in FIG. 3 (c), the operation of the air cylinder (9) for moving the profile receiver lowers the profile receiver (8).
It comes off the hook (5) of the profile gripper.

However, since the profile is released only by its own weight, as shown in FIG. 2D, the hook (5) depends on the shape of the profile and the condition of the cut portion (2) of the profile. May be caught.

[0006]

As shown in FIG. 2 (a), when the profile does not come off from the hook of the carrier bar, the worker must go to that location and remove it. Is not transported, which is a factor that reduces productivity, and as shown in the schematic diagram of FIG. 5, the worker gets on the carrier bar and removes the profile in a squatting position, which is unsafe. Work was required, and there was a case where a person fell down accidentally in addition to a cut in his hand.

Accordingly, an object of the present invention is to prevent the productivity from being hindered because the hook of the carrier bar does not come off when the profile is released from the carrier bar in the vertical hanging surface treatment process of the long aluminum sash. Another object of the present invention is to provide a method and an apparatus for releasing a profile from a carrier bar, which eliminates unsafe operations and eliminates security concerns.

[0008]

As a result of research to achieve the above object, the present inventor has found that a hook of a carrier bar gripper and a cutout of a profile placed in a profile receiver while being gripped by a chuck. Rather than releasing only the weight of the profile from the hook fitted to the profile, a profile pushing device is provided that forcibly pushes the profile in conjunction with the lowering of the profile receiver,
By automatically operating with the air cylinder attached to this, and after the notch is completely separated from the hook, the press-down device is restored to the old one, it is possible to reduce time loss and eliminate unsafe work, and the above-mentioned problem is solved. The present inventors have found out that they can solve the problem and reached the present invention.

Therefore, the present invention firstly provides an apparatus for automatically releasing a product profile (1) from a product transport carrier bar (3) in a vertical hanging surface treatment step of a long aluminum sash profile. , Comprising a combination of a profile presser (10) fixed at a predetermined position above the end of the profile (1) and a profile receiver (8) arranged below the profile (1). The depressing device (10) comprises an air cylinder (11) and its piston rod (12) and a profile push rod (13) connected thereto, while a profile receiver (8).
Is connected to an air cylinder (9) for elevating and lowering the air cylinder (9) and the air cylinder (1).
In conjunction with 1), the profile receiver (8) and the profile push rod (13)
Are designed to descend at the same speed.
In addition, when performing vertical suspension surface treatment of a long aluminum sash profile (1), a product transport carrier bar (3) is placed on a plurality of horizontally disposed profile receivers (8) that can be moved up and down by an air cylinder. A step of placing the profile (1) held by the hook (5) and the chuck (6) on the hook and releasing the chuck (6) of the profile gripping portion of the carrier bar (3) from the profile (1). A method for releasing a profile (1) from a carrier bar (3) including a chuck (6) after releasing the chuck (6) from the profile (1), above the end where the cut (2) of the profile (1) is located. (10) a section press-down device that moves up and down by a piston rod (12) of an air cylinder (11) provided at a predetermined position
While lowering the profile receiver (8) at the same speed, the profile push rod (1) provided at the lower end of the press-down device (10).
In step 3), the profile (1) is forcibly pushed down, and after the profile cut (2) reaches a position completely separated from the hook (5), the piston rod (12) attached to the pushing-down device (10). ) To return the press-down device (10) to its original position.

[0010]

According to the present invention, as shown in a side view of FIG. 3 in which the periphery of a profile pushing device is enlarged, an air cylinder is located at a predetermined position above an end where a cut portion (2) of the profile is located. (11) is provided, and the section press-down device (10), which is raised and lowered by the piston rod (12), descends in conjunction with the section receiver (8), and the section pusher provided in the section press-down apparatus is provided. Since the bar is forcibly pushed down by the rod (13), the hook (5) of the gripping portion is not caught and no time loss occurs.

FIG. 3 shows a state in which the tip of the profile push rod (13) pushes down the profile (1) to a position where the hook (5) of the gripping portion is just separated from the cut portion (2).

After the section press-down device (10) has descended a certain distance, it is returned to the original position by operating the piston rod (12) again, and all processing is automatically performed, such as waiting for the next operation.

[0013]

1 (a) to 1 (c) are side views showing a procedure for releasing a profile using a profile release device in the present embodiment, which will be described below with reference to this figure.

(1) First, an air cylinder (9) is formed by a conventional method.
A plurality of profiles (8), which can be moved up and down, are placed on a carrier bar, and the profiles (1) held by the hooks (5) and the chucks (6) are placed on the carrier bar. The part chuck (6) is released from the profile.

(2) A profile pushing device (10) which is raised and lowered by a piston rod (12) of an air cylinder (11) provided above an end where the cut portion (2) of the profile is located, and a profile receiver (8). ) Is lowered at the same speed, while the profile pushing rod (1) provided at the lower end of the profile pushing device (10).
The profile is pushed down at 3) and continues to descend until the profile cut (2) reaches a position completely separated from the hook (5).

(3) Thereafter, the piston rod (12) connected to the profile pushing device is operated to return the profile pushing device (10) to the original position.

[0017] As described above, the troubles caused by catching have been conventionally caused 20 times per day (7.5 hours), and the productivity due to the reduction of the loss time is about 2.3%.
Improved.

Also, the removal work by the operator is eliminated, and the unsafe work can be eliminated.

[0019]

As described above, according to the method of the present invention, a profile bar is pressed down on a plurality of profile bars arranged horizontally while the profile bar is being held by a carrier bar with a hook and a chuck. The device is lowered at the same speed as the profile receiver, and the profile is forcibly pushed down until the cuts in the profile are completely separated from the hooks. There is no need to remove it and no security concerns.
