Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for automatically supplying long materials such as pipes and round bars to processing sections such as roll processing and die processing.

The method for supplying long material to the processing section is to push up the long material in the stock section from below and roll the overflowing material one by one to bring it out 11y. The method of putting it in a ditch or gutter is widely adopted. However, since this method uses rolling 17 in the middle, it cannot be used for long 4A products that have poor rolling properties, such as silk and annealed products.・This method not only requires a large amount of space such as stock space and storage space, but also requires large machinery and equipment.
There were drawbacks that could result in high costs.

The main purpose of the present invention is to eliminate the drawbacks of the prior art described above and to provide an apparatus that can easily and automatically feed even long materials that are difficult to roll.

According to the present invention, such an object is achieved by using a reduced pressure suction vat and a chucking device in combination, and by gripping the long material lifted by the suction vat with the chucking device and holding it in the size of the material receiving part of the processing section. This can be achieved by moving.

The present invention will be described below with reference to the drawings. As shown in FIG. It is placed so that it is in front of you. However, by means of the lever device B, the long materials, such as copper pipes P, to be fed to the pinch roller 28 are accumulated on the tray 1 and moved on the rail 5, which is laid in a direction perpendicular to the feeding direction. A tray 1 is placed on a trolley 2 that can be
ll! is provided below the main part of the device 6.

The supply device i't is equipped with a reliquary 2d, a lifter 6, and a level detector, such as a phototube device 4, which can maintain the level of the EL tube at the top.
A cylinder 9 is attached to the tip of the arm 8 extending from the frame 7 of 6.
The rail 5-1- is mounted so that it can be moved left and right by the power from the sensor 10 which is taken out through the rail 5-1.

The feeding device 6 is disposed at the tip end of a frame 7 that starts from the 11 side of the pinch roller 28 and extends parallel to the feeding direction of the material 1.
y1 descending platform 16, a moving plate 16 that moves back and forth via a screw 15 by the operation of a motor 14 attached to this platform, and a support plate 18 for how to use this moving plate. It consists of a claw side piece 11, a vacuum suction vat 24, and a chucking device 25.

The suction bat 24 and the chucking device 25 are arranged close to each other so as to be located on a line connecting the pinch [J-ra 28 and the sensor 10] in a plan view.

The motor 14 on the lifting platform 16 is connected to a chucking device t2.
After the chuck 26 of No. 5 is closed, the movable plate 16 is actuated to advance along the guide rod 17 to the pinch l''-ra 28i+1jl and stopped, and after the chuck 26 is opened, the movable plate 16 is actuated It is designed to move back and forth, but
This cannot be supported even if an air cylinder is used.

The support plate 18 that supports the suction pad 24 and the chucking device 25 is provided on the 11IIj side of the movable plate 16, and
The tip of the steel pipe to be fed is pinched [j-ra 28
It is designed to absorb and alleviate the shock when it is pulled.

Adsorption Para) 24 iltIt is attached via the base plate 22 and spring 23 to the tip of the cylinder 21 which is hooked to the support plate 18, and when it is lowered by the operation of the cylinder 21,
Although the collision with the lower copper pipe P can be alleviated, there is no need to slide between the base plate 22 and the base plate 22 via a flexible hose or pipe such as a rubber hose. There is no problem if you install it. This suction pad 24 is still connected to the vacuum pump via the pulp, and is lowered by the actuation of the cylinder 21 in response to the picking start signal. By adsorption and return of cylinder 21.
- Lift up and hold one end of a steel pipe at a predetermined height.
Then, the chucking device 25 operates and the chuck 267
After J'-closes, the reduced pressure is released.

A chucking device 25 disposed adjacent to the suction pad 24 is of a type in which a chuck 26 can be opened and closed by air, and the chuck 26 is normally open.

However, the suction pad 24 held one end of the copper pipe and burned by -1.
Knowing that the middle part goes inside/here, close it and move the plate 16
After moving forward and stopping the lower part, the steel pipe clamp can be released.

In the configuration shown below, the pinch [1-ra 28
and the level of the chucking device 25 is interposed. Then, the pipe 1 in which the copper pipes (2) are accumulated is placed on a predetermined position on the lifter 3, and the platform 2 is moved to a predetermined position. Thereafter, the lifter 3 is operated to raise and lower the tray 1, and the level of the steel pipe at the uppermost stage is adjusted to the operating level of the supply device B by using the phototube device 4. There is no problem in ensuring the level of the steel pipe at the top stage is performed while the cart 2 is moving by 1 before moving by a predetermined distance fff-4.

After that, actuate cylinder 9 to lower +nza 1o,
The sensor 10 is returned by inching the reliquary 2 so that the steel pipe on the uppermost side comes directly below, and the cylinder 21 is operated to lower the suction pad 24 while reducing the pressure inside it. As a result, as shown in FIG. 2, the bat 24 is attracted to the middle of the copper 'f'
In other words, the copper pipe P adsorbed by the butt 24 has a piece ☆:T,i (lllj holds it) as shown in Fig. 3.
-, and part of the way enters the open chuck 26 of the adjacent chucking device 25.

When the cylinder 21 returns, the chucking device 25 operates and closes the chuck 26, and the absorption of the bat 24 takes place for one night or seven days.
11. After that, the motor 14 is activated. In response to this, 1: Since the movable plate 16 moves forward via the lisfrille 15, one end i
ll! The removed copper pipe P is attached to the chuck 26.
u hold the cuff 1 and pull the pin roller 28 upwards 1;
As shown in FIG. 4, the tip passes through a trumpet-shaped guide 27 and is guided to the pincher 11-ra 28.

At this time, since the steel pipe 1 is firmly held in the middle by the chuck 26, it will not come off from the chuck 26 even if a large amount is pulled.

The moving plate 16 advances inT to 7, and the tip of the copper pipe P is pinched CJ.
- The arming motor 14 that reaches the roller 28 stops, drives the pinch roller 2B, and the chuck 26 is opened.
Therefore, the pipe 1' is pulled by the pinch roller 28 and fed from the tray 17 to the straightening machine which is the force n]I part.

If the timing of the tension of the pinch roller 28 and the opening of the chuck 26 are slightly different, there is a risk that the chucking device 25 will be pulled together with the copper pipe P toward the pinch [''-rough 8], but the chucking device 25 will be supported. Since the A-needle 20 is interposed between the support plate 18 and the movable plate 16, it is possible to absorb and alleviate the shock caused by the pull 71'1-.

In some cases, the chuck 26 is a chucking device 25
is pulled together with copper pipe J.! 17. The support plate 18 may be opened when it is moved.

When the chuck 26 is released, the motor 14 operates 11J, so the movable plate 16 moves back together with the restored suction/chuck 24 and chucking device 25 and returns to the original state, waiting for the next operation.

Waiting for the return of the moving plate 16 and the rear end of the steel pipe pulled by the pinch roller 28 coming out of the enclosure 1 from the tray 1'', the sensor 10 and the trolley 2 work together again to lift the pipe next. Place the copper pipe under the suction pad 24 1. /, l, so each part of the device 6 sequentially performs the above operations again. By repeating this, when the first stage of steel pipe runs out, the light IIL
The lifter 6 is actuated by a signal from the pipe device 4 to raise the next stage steel pipe to a predetermined position. The sensor 10 and the truck 2 then work together to start feeding the next stage of steel pipe.

In this case, the feeding start side of the next stage is set to the end of the previous stage (nil) in order to shorten the waiting time, but it may be 11+1! and I~, which is the same as the start level j of the previous stage.

FIG. 5 shows another example of the suction pad.

In this example, a plurality of suction pads 24, for example, three, are arranged in a staggered manner so as to overlap each other within a width that is equal to the dimension between the open ends of the chuck 26 when it is open. Each pad 24 is hooked to the base plate 29 via a rubber hose 30 and a soft spring 31, and is connected to a vacuum pump as a pressure reduction source via a switching valve, and is placed under a certain suction pad. If there is no steel pipe to be adsorbed (-), the next suction pad will be depressurized.In this case, it is undesirable to switch from the leftmost ('', with a claw) to the next.

With such a butt configuration, when descending, not only can the collision with the steel pipe be alleviated, but also the positional relationship with the copper pipe to be picked up can be slightly reduced. But Finn) can do something. Furthermore, by expanding the area surrounding the trap 11i'i for suction, it is possible to reduce the frequency of movement of the table 1 (2) and to omit the sensor 10.

According to the device according to the present invention represented by the above example, the following effects are achieved, and its practical value (++'Ci
l, extremely large.

(1) Compared to the rolling method, no space is required for the rolling part.

(2) It is possible to pick individual pieces even if the material is difficult to roll.

(6) Materials placed randomly 1. By using the suction pad for the plate number, even in a state where the plate number is different, it is possible to reliably feed the plate by AA.

(4) Since it is a method in which the material is moved forward after being pulled down, it is suitable as a picking method for long materials, and picking is stable.

(5) Since it is pulled up by vacuum adsorption, it is not limited to the old quality of the long material t1.
