Description

Material Separator {DESTACKER}

The present invention relates to a material separating apparatus.

In general, in a press line for producing vehicle body parts (Panel), conventionally, only steel (magnetic) material was produced, and the raw materials were separated and washed one by one from a pile of materials, and automatically introduced into the press.

A device that automatically separates and inserts material into a press is sometimes called a Destacker equipment.

Disteka equipment, which is a material separation device, uses the characteristics of a magnet called magnetic floater (MAGNETIC FLOATER) to inject the separated material into the press.

1 and 2 are views showing the configuration of the automatic material input device according to the prior art.

1 and 2, the automatic material input device according to the prior art is a DESTACKING unit 110, a magnetic floater (120), a vacuum cylinder (VACUUM CYLINDER) 130, a magnetic belt MAGNETIC BELT CONVEYOR (140), WASHING UNIT (150), CENTERING DEVICE (160), DOUBLE BLANK (170), FILTERING UNIT It is configured to include.

With reference to Figures 1 and 2 will be described the operating state of the automatic material input device applied in the production of steel (STEEL) using the automatic material input device according to the prior art.

First, a pile of material is loaded into a crane saver by a forklift.

Subsequently, the pile of material on the crane saber is moved to the destacking unit 110, and the magnetic plotter 120 separates one sheet from the pile of materials.

Thereafter, the vacuum cylinder 130 descends, absorbs one piece of material, and then rises, and one piece of material is attached to the magnetic belt conveyor 140 and transported.

At this time, when two sheets of material or bad materials are adsorbed and adhered, the magnetic belt conveyor 140 is transferred backward and loaded on the double blank box 170.

One sheet of material is washed cleanly as it passes through the cleaning device 150, and is transferred to the centering device 160. When one sheet of material is centered, a series of processes of continuously absorbing the material into the press by using an automated equipment such as a loader (loader) are continuously performed. Repeated operation results in automatic production.

3 is a view illustrating a material separation method using a general automatic material input device.

Referring to Figure 3, the material separation method when producing a steel material is as follows.

First, when the magnet has the magnetic pole of the N pole, the material has the magnetic pole of the S pole.

At this time, the pushing force between the materials is generated, and the pulling force is applied to the material and the magnetic plotter to separate the material.

The separated material is adsorbed to the vacuum cylinder 130 to which the vacuum cup is attached and then transferred to the next process.

By the way, in recent years, non-magnetic material (aluminum) is produced for weight reduction of a vehicle body.

In this state, it is difficult to separate materials using a conventional material separating apparatus, and two materials are introduced into the press, which may cause equipment stoppage and mold breakage.

In order to solve this problem, it is necessary to use a non-magnetic material separating device, but it is not easy to build a line that can automatically produce non-magnetic material (aluminum). And the risk of safety accidents.

The hanger 410 of the robot further comprises a material detecting sensor 416 for detecting overlapping adsorption of the material.

The adsorption unit is mounted on the hanger 410 of the robot to absorb the material loaded in the pile of material.

The adsorption part includes an adsorption rod 412 and a vacuum cup 414.

The suction rod 412 is formed in a hollow cylindrical shape, at least one is installed.

Suction rods 412 are disposed at a spaced interval at a set interval.

The adsorption rod 412 is composed of three, as shown in Figure 4, the middle of the three adsorption rod, the length of the adsorption rod is formed longer than the adsorption rod length of both ends.

The vacuum cup 414 is coupled to the end of the suction rod 412 to adsorb the material.

The material separating unit 420 is mounted on the upper side of the material restricting unit and separates the rising material from the uppermost material, such as the uppermost material rising through the material conveying unit.

The material separating part 420 includes an actuator 421, a driver, and a material contacting part 424.

The actuator 421 is driven in accordance with the supply of external force to generate a driving force.

Actuator 421 is connected to the air supply and discharge is configured as a pneumatic cylinder in which the rod moves in accordance with the supply and discharge of air.

The driving unit transmits power according to the driving of the actuator 421.

The driving unit includes a cam 422 and a shaft 423.

The cam 422 forms a curve on one inner surface of the material contact portion 424.

The curve of the cam 422 is formed such that the workpiece contact portion 424 contacts the top side of the workpiece in the downward direction.

The shaft 423 is connected to the cam 422 and the actuator 421, respectively, and moves along the curve of the cam 422 by an external force transmitted from the actuator 421.

The material contact part 424 is in contact with the material raised from the material pile through the material conveying part according to the external force transmitted from the driving part.

The material contact portions 424 are formed at both front sides of the actuator 421, respectively.

On the other hand, the embodiment of the present invention further comprises an air injection unit for supplying air to the material is raised from the pile of material through the material conveying portion.

The material separated through the material separator 420 includes a nonmagnetic material.

On the other hand, the embodiment of the present invention further comprises a magnetic material separating portion for separating the magnetic material among the materials loaded in the pile of material.

The magnetic material separating part is mounted at both ends of the pile of material, and the polarity of the magnet and the material is formed differently according to the power supply, so that the material is pushed out and the pulling force is applied to the material and the magnet to separate the material one by one. It consists of a magnetic plotter.

The magnetic plotter includes a first magnetic plotter 400 mounted on one side of the pile of materials and a second magnetic plotter 402 mounted on the other side of the pile of materials.

The magnetic plotter according to the embodiment of the present invention can be used as a material control part when separating the nonmagnetic material.

On the other hand, the material separating unit 420 may be installed as much as the number of magnetic plotter for the production of magnetic and non-magnetic material in common.

As described above, steel, which is a magnetic material, is separated one by one using a magnetic plotter from a pile of materials, but an aluminum material is a nonmagnetic material, and thus is not separated as a magnetic plotter. Therefore, a separate material separation method should be used.

4 and 5 will be described a material separation method according to an embodiment of the present invention.

First, in the production of the magnetic material of the magnetic body, the actuator 421 shown in FIG. 5 performs the reverse operation, advances only the magnetic plotter by the required amount, and separates the material, and then the vacuum cup 414 of the adsorption part adsorbs the material. To increase.

If the actuator 421 performs excessive forward movement beyond the set range, scratches occur due to excessive contact between the material contacting part 424 and the material, and foreign substances are generated, resulting in unevenness of the product.

In the production of non-magnetic material (aluminum), the magnetic floater is advanced as necessary to perform a material regulation function to guide the material, and as shown in FIG. 4, the material separating part 420 mounted on the upper portion of the magnetic plotter. ) To separate and supply the material.

The order of operation is that the adsorption rod 412 of the material conveyance unit, which is mounted on the hanger 410 of the robot, first descends and absorbs the material through the vacuum cup 414 to ascend.

That is, the front and rear of the aluminum material pile is regulated so that the material is not disturbed using the material control part, and the robot hanger 410 descends to absorb the material and ascend.

The primary separation of the material is made by stepping the height of the vacuum cup 414 at the side and the middle of the material so as to easily separate the material when the material is absorbed and ascended.

However, the material on which the oil film is formed rises in a state where it is not separated.

In this way, if the material does not fall apart even though the material is separated first, the material contacting part 424 and the material contact with the driving of the material separating part 420, and the material is raised through the material contacting part 424. Unnecessarily rising material falls off while scratching.

This is called the secondary separation operation of the material.

At this time, the actuator 421 moves forward to drive the material bonding portion along the cam 422 curve.

The material adhesive part is spun by the operation of the driving part to separate the material primarily.

In spite of this operation, when the material is not separated, it can be easily separated by supplying air to the rising material side, and the vacuum cylinder continuously forms one side shape of the material according to the spanning operation of the material bonding portion. As you scrape up, the material is completely separated.

When the material is completely raised, the actuator 421 performs the reverse operation.

By repeating this operation, the nonmagnetic material is separated and produced.

If the fall does not fall even in this section, the material is repeatedly raised by the material sensor 416 is detected and the hanger 410 of the robot is lowered to absorb the material again.

The material, which does not fall upon the adsorption of the material again, is transferred to the double blank box (D / B BOX) for disposal by the robot's backward motion.

That is, if the material is not separated, it is detected that the material is overlapped by the material detecting sensor 416 attached to the robot hanger 410, and in this case, the material is tried to separate while descending once more without inputting the material and the material is still there. If it rises in duplicate, it will be discharged to a separate box provided separately.

On the other hand, the material normally transported by the robot is transferred to the conveyor belt, the automatic production is continuously made by this series of repeated operations.

As described above, the material separating apparatus according to the present invention can solve the problem that the equipment is damaged as two materials are input, and improve the equipment down time due to the input of two materials.

In addition, it is possible to reduce the weight of the vehicle by applying an aluminum material by building a non-magnetic material production system.
