Abstract

PURPOSE:To surely transfer a plate material sheet by sheet by suspending positioning members, brought into contact with a plate material upper surface when the plate material is sucked on sucker members by lowering down a mover, from the mover so as to actuate separating pawl units protruded always in an accurate position. CONSTITUTION:When the uppermost plate material 1a piled together is sucked by sucker members 3 by lowering down a mover 2, positioning members 5 are brought into contact with an upper surface of this plate material 1a. Even when a machine body is temporarily tilted and even when the plate material 1a is bent, since the plate material 1a is retained from above by the positioning members 5, separating pawl units 4 suspended from the mover 2 are arranged always in a fixed position relating to the positioning members 5. Even in the thin plate material 1a, the separating pawl unit 4 is accurately protruded to a desired position, and a lower side plate material 1b piled together can be separated. Further, when air nozzles 14 are provided, air is jetted toward a clearance, generated between the upper side plate material 1a and the lower side plate material 1b, by deflecting the plate material 1b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material separating apparatus such as a plate material separating and supplying apparatus.

[0002]

2. Description of the Related Art In general, a plate material separating / feeding apparatus stacks a plurality of plate materials on a storage frame, a movable body is provided above the plate materials so as to be vertically movable, and a suction pad is provided below the movable body. Then, the moving body is lowered and the stacked uppermost plate material is adsorbed by the suction pad, the moving body is raised, and the moving body is further moved to supply the plate material to a plate material processing machine such as a press machine. To do.

When this plate material is sucked up by the suction pad and lifted, the plate materials may come into close contact with each other due to the influence of an oil film such as an anticorrosive agent, so that two plate materials may be lifted together. A plate material separating device for separating is provided.

Conventionally, various types of plate material separating devices have been proposed, but in each case, a pair of separating claws are arranged on the upper part of the storage frame, and the moving body is raised to the height of the separating claws and temporarily stopped. This is a structure in which the separating claw body is inserted between the plate materials that have risen due to the overlap and the plate materials to project and the lower plate material is dropped.

[0005]

In the conventional plate material separating apparatus, as described above, the moving member has to be stopped and lifted to a height at which the separating claws project and can be reliably separated. The higher the accuracy, the higher the accuracy required for the movement control of the moving body. Therefore, an expensive moving body control cylinder or the like is required.

Further, even if the accuracy of the movement control is improved, the position of the separation claw body with respect to the plate material is displaced if the machine body or the plate material is tilted or distorted. Therefore, the position of the separation claw body must be finely adjusted successively. For example, there is a drawback that the plate material cannot be reliably separated and dropped.

In addition, the method of simply inserting the plate member and the plate member separating claw member has a drawback in that the separation and fall cannot be ensured.

The present invention solves such problems and provides a plate material separating apparatus excellent in practicality.

[0009]

The gist of the present invention will be described with reference to the accompanying drawings.

A movable body 2 is provided above and below the stacked plate materials 1 so as to be vertically movable, and the plate materials 1 are provided below the movable body 2.
An adsorbing member 3 for adsorbing the adsorbent 3 is provided, and a separating claw body 4 for separating the superposed plate material 1b is vertically provided on the moving body 2, and the moving body 2 descends on the moving body 2 to adsorb the adsorbing member 3 on the plate material 1. At this time, the positioning member 5 that abuts on the upper surface of the plate 1a is vertically provided, and at least one pair of the separating claws 4 are provided.
The side surface 1a of the plate member 1a is provided at a position abutting a ', and the other separation claw body 4 is provided at a position abutting the side surface 1b' of the plate member 1b located below the plate member 1, and is attracted to the suction member 3.
The plate material separating apparatus is characterized in that the lower side of the contact side surface 4'of one separation claw body 4 that abuts against a'is formed as a downward tapered surface 13.

Further, the separating claw body 4 is provided with an air nozzle 14 ejecting between the plate material 1a adsorbed by the adsorbing member 3 and the plate material 1b superposed on the lower side of the plate material 1a. The present invention relates to the plate material separating device according to claim 1.

[0012]

When the moving body 2 descends to adsorb the uppermost plate material 1a stacked by the adsorbing member 3, this plate material 1a
The positioning member 5 contacts the upper surface.

Even if the machine body is tilted or the plate material 1 is distorted, the positioning member 5 presses the plate material 1a from above, so that the separation claw body 4 hung vertically on the moving body 2 is always against the positioning member 5. Since it is arranged at a fixed position, even if the plate material 1 is thin, the separation claw body 4 is accurately projected to a desired position, and the overlapping lower plate material 1b can be separated.

When the plate member 1a is raised as the moving body 2 is raised, even if the plate member 1b is superposed on the lower side of the suction plate member 1a, each separation claw member 4 projects to the side of the plate member 1 and one of the separation members is separated. The claw 4 abuts on the side surface 1a 'of the upper plate 1a, and the other separating claw 4 abuts the side 1b' of the lower plate 1b, so that the lower plate 1b slides with respect to the upper plate 1a. Then, the sliding edge 1b "of the lower plate member 1b is abutted against the downward tapered surface 13 formed below the contact side surface 4'of the one separation claw body 4 and is pressed by the downward tapered surface 13. Therefore, the plate material 1b slightly bends downward, and the contact of the plate material 1b is weakened by this deflection, and the plate material 1b falls downward.

Further, when the air nozzle 14 is provided, air is jetted toward the gap formed between the plate member 1b and the upper plate member 1a due to the bending of the plate member 1b.

EXAMPLE In this example, several storage frame rods 7 are erected on a machine base 6, and a large number of thin plate materials 1 are stacked and placed inside the storage frame rods 7 to provide the uppermost plate material. 1a is sequentially sucked and raised one by one, and the uppermost plate 1a is always moved to the moving body 2
In order to match the lowering position of the suction member 3, the sensor detects the height position of the uppermost plate 1a, and the drive motor 8 rotates the screw rod 20 to control the bottom table 11 to move up.

In this embodiment, a moving body 2 is arranged above the stacked plate materials 1, and a pair of adsorbing members 3 are vertically provided on the moving body 2.

A slide fitting groove 9 is formed in the moving body 2, and a pair of mounting rods 10 and 10 are fitted in the slide fitting groove 9 so as to be opposed to the outer right and left sides of the suction member 3 and vertically. At the lower ends of the mounting rods 10 and 10, sharpened separation claw bodies 4 and 4 are attached to the side portions of the plate material 1 so as to be slidable so as to face each other.

Positioning member mounting rods 12 and 12 are horizontally projected inward in the middle of the respective mounting rods 10 and 10, and the projections are provided at the tips of the positioning member mounting rods 12 and 12. Positioning members 5, 5 in the form of a screw rod are threaded and protruded so as to be adjustable.

In this embodiment, the positioning member 5 is screwed in accordance with the thickness of the plate material 1 to be used to adjust the degree of protrusion, and the plate material 1
The mounting rods 10 and 10 are slid and adjusted according to the width dimension, and the separation claws 4 are always adjusted in advance so that they can be projected to the correct position in advance. I am able to do it.

The separation claw body 4 of this embodiment will be described in more detail.

When the movable body 2 is raised and moved laterally, the movable body 2 is projected, and the lower plate material 1b that has been polymerized is dropped between the original storage frame rods 7. The uppermost plate 1a having the contact tip side surface 4'adsorbed by the adsorbing member 3
Position of sliding the lower plate member 1b with respect to the plate member 1a by abutting the contact tip side face 4'of the other separation claw member 4 against the side face 1a 'of the lower plate member 1b. And a downward taper surface 13 is formed below the contact tip side surface 4'of one of the separating claws 4 that abuts against the side surface 1a 'of the plate 1a.

Therefore, when the separating claws 4 project from the left and right, the lower plate member 1b slides with respect to the upper plate member 1a, and the sliding edge 1b "of this plate member 1b abuts against the downward taper surface 13. As a result, the plate member 1b is slightly bent downward due to being pressed by the downward tapered surface 13.

Due to this deflection, the adhesion of the plate material 1b is weakened and the plate material 1b drops downward. In this embodiment, in order to further ensure this peeling and drop, in the gap formed between the plate material 1b and the upper plate material 1a due to the deflection of the plate material 1b. An air nozzle 14 for ejecting air toward the separation claw body 4 is provided.

Therefore, in this embodiment, the movable body 2 descends and the plate member 1a is adsorbed by the adsorption member 3 of the movable body 2 and ascends, and at the same time the left and right separation claws 4 project inward before the lateral movement. Air spouts from the air nozzle 14 and plate material 1a
Even if the lower plate material 1b is closely adhered and polymerized, the lower plate material 1b can be reliably separated and dropped between the lower storage frame rods 7 and the plate materials 1 can be supplied one by one.

In the figure, reference numeral 15 is a vertical movement cylinder device for the moving body 2, 16 and 16 are vertical movement guides, 17 is a lateral movement mechanism for moving the moving body 2 laterally, 18 is a transfer and drop portion of the plate material 1, and 19 is It is a transfer belt that transfers and supplies the plate material 1 that has been transferred and dropped.

[0027]

As described above, according to the present invention, when the plate material is always sucked and raised, the positioning member is brought into contact with the upper surface of the plate material. Therefore, as in this embodiment, one of the separating claws is placed on the side surface of the upper plate material. Accurately abut the side of the lower plate that overlaps the other separating claw, or insert the separating claw between the plates accurately and project it so that the projecting operation is performed at a preset accurate position. Even if the machine body is tilted or the plate material is bent or distorted, it does not malfunction as in the past and does not require a highly accurate and expensive cylinder device, and the separation claw is always in the correct position. The plate material separating device has an extremely excellent practicality in which the body can be projected and transferred reliably one by one.

Further, one of the separating claws is abutted against the side surface of the upper plate member, and the other separating claw member is abutted against the side surface of the lower plate member, so that the lower plate member slides with respect to the upper plate member. However, the sliding edge of the lower plate member is abutted against the downward taper surface of one of the separation claws, and the overlapping plate member bends downward, so that the overlapping plate member can be reliably dropped.

When the air nozzle is provided, air is jetted toward the gap formed between the lower plate member and the upper plate member by the deflection of the lower plate member, so that the lower plate member can be more reliably separated and dropped.
