2. Description of the Related Art In a bending machine of this kind, a manipulator is generally provided with a traveling platform which moves in the front-rear direction at a position of an opening groove between left and right tables on which a plate is placed, and has an insertion port for inserting the plate. The C-type frame is mounted on the carriage, and the C-type frame is equipped with a clamp for holding and holding the plate material. The clamp is equipped with a receiving plate on the lower part of the C-type frame and a holding plate on the upper part. The receiving plate is attached to the upper end of the rotating shaft driven by the motor, and the presser plate is attached to the lower end of the free rotating shaft. The receiving disc and the holding disc are disc-shaped, also called buns, which are rotatably provided with a wide contact surface with the plate material. In addition to the large diameter, it is difficult to catch a small gripping margin, and in addition to driving the receiving disc, Since the device has a protruding shape supported by the front bending machine, access is restricted when loading and unloading narrow plate materials. In particular, when the front-rear width (expected width) of the plate material is narrow and the bending has already been formed at both ends, the restriction becomes particularly severe. there were.

[0003] Conventional sub-clamps are mounted in a pair on the left and right sides of a C-shaped frame so as to sandwich a main clamp, and have a structure that can be extended and retracted in order to perform an auxiliary function. That is, when the main clamp feeds the plate material by the advancement of the C-shaped frame, the shortage is sent out by extension at the time of carry-in, and the main clamp is pulled out to the main clamp by contraction at the time of carry-out. It was intended to be drawn out by reduction.

[0005] First, in the case where a bending process is performed on one end of a plate material and then the other end is bent,
Because the main clamp needs to hold down the plate material, the sub-clamp pulls out the plate material and positions it.However, since the distance to pull out is limited as a reduced dimension, in the case of a small plate material that requires only a small distance to pull out Positioning is possible, but in the case of a large plate material, re-gripping is repeatedly performed to reach a predetermined position, causing a loss of re-gripping operation and making work inefficient.

In addition, since the sub-clamp catches the end of the plate at the forward position of the main clamp when the main clamp is carried in, the relative position required between the main clamp and the sub-clamp must be set in relation to the front-rear width of the plate. was difficult. At the time of unloading, the main clamp is at the forefront advance position and holds the position until the sub-clamp grasps the plate, so retreat to release the plate and hold the next plate until it is discharged from the table. However, there is a problem that the delivery of the next plate is delayed. In other words, temporarily
If the main clamp already grips and waits for the next plate at the time of unloading and releasing the plate by the sub-clamp, it is considered that role sharing functions effectively and time loss is reduced and efficiency is improved. .

Provided a manipulator for a plate bending machine that eliminates time loss and improves work efficiency, because the main clamp has already taken the next plate material and taken the loading posture and waited until discharging was completed. The purpose was to.

In order to achieve the above-mentioned object, the present invention is configured as described in claims 1 to 3, according to which a main manipulator and a sub-manipulator are provided. And move independently of each other, so when carrying it in for processing of the plate material,
It is gripped by the clamp of the main manipulator and sent to an appropriate position (the turning position is good), and the submanipulator sends in the missing part, but the sub clamp does not have any restrictions regardless of the front and rear width of the plate. The end of the plate can be picked without receiving. In this loading posture, when bending is performed on one end in the bending machine and then turning to perform processing on the other end, the sub-manipulator is retracted and the plate material is immediately moved to the clamp position of the main manipulator. The center can be located. In addition, there is no restriction on the positional relationship where the sub-clamps pinch the ends at the time of pulling out for turning and also at the time of reloading after turning. Further, if it is to be carried out after the turning process, if the main manipulator is already retracted at that time, it is possible to hold the next new supply plate material and to stand by (for example, in FIG. 1, a two-dot chain line). Indicates the standby position), the sub-manipulator takes over the carry-out with one hand, and the main manipulator can be moved to carry-in at the same time when the old processed plate material is discharged from the table. From now on, it will be the same as above. In FIG. 2, Pa indicates the supply direction of the new plate material,
b indicates the direction in which the processed plate material is discharged.

Since the left and right sub-clamps are always kept in a parallel state because the left and right sub-clamps need to be equally gripped by the sub-manipulator, according to the second aspect of the present invention, the simultaneous and parallel driving is performed by the rotation of a common motor. Can be reliably obtained with a simple structure.

In the above-described series of operations, when the plate is turned, the sub-manipulator needs to be retracted to a position where it does not hinder the turning. For this purpose, a retracted position (for example, the position is indicated by a two-dot chain line in FIG. 1) or an advanced position may be adopted, but the cue of the sub-manipulator is retracted as described in claim 3. Withdrawal time can be further reduced.

In the present invention, the drive mechanism of the main clamp 5 and the sub-clamps 7, 7 is not particularly limited. In the case of the embodiment to be described later, a crank mechanism for moving the elevating body 55 up and down by the servo motor 59 is used for the main clamp 5 and the air cylinder 25 is used for the sub clamps 7, 7. It can also be by a mechanism or an air cylinder. With the crank mechanism, workability is improved because quick opening and closing of the crank is obtained,
Further, since a closing boost is obtained at or near the bottom dead center of the crankpin 63, it is suitable for energy saving.

As described above, according to the present invention, since the main manipulator and the sub-manipulator move independently of each other, the main clamp can be positioned at the center of rotation by the main clamp so that the front and rear positions of the plate material can be adjusted. Regardless of the width, it is performed all at once by the unrestricted retraction of the sub-manipulator, and is not restricted by mutual gripping.In addition, by the time the sub-manipulator discharges from the unloading table, Since the main manipulator can also take on the role of having the next new sheet material already caught and ready for carry-in, there is no time loss and the work efficiency of sheet metal and other sheet materials is dramatically improved. There is an excellent effect that it can be increased.

The main clamp 5 is configured by attaching the receiving plate 15 to the lower end of the free rotation shaft 13 and the holding plate 17. And C type frame 3
In the state where the plate material W as a work inserted into the C insertion port is clamped, the plate material W is carried in (or carried out) by the reciprocating operation, and the plate material W is turned by the rotation of the receiving plate 15. These loading, unloading, and turning operations are performed in the bending machine B in an open state in which the upper die 8 is raised with respect to the lower die 9. Reference numeral 10 denotes a presser ram that moves the upper die 8 up and down. Then, after the position is set by the manipulator M, while the plate material W is being pressed by the upper die 8, the bend blade 12 is operated to perform upward bending or reverse bending. FIG. 1 shows a state where the plate material W is bent twice at both ends, and the sub-manipulator Mb is now in a turning position (in FIG. 1, a solid line position of the main clamp 5).
