Description

[Detailed description of the invention] a. Industrial application field The present invention relates to a method for positioning a plate provided on a workbench of a plate processing machine.
This relates to a device that supplies plate material, which is a workpiece, to position A.

b. Prior Art A plate feeder that presses one end of a plate against a plate positioning device, such as a back gauge, provided in a conventional plate processing machine is widely used in jarring machines and the like.

However, in a plate processing machine in which the cutting head moves under numerical control, it is not possible to press one edge of the plate as described above, and the specific
It is necessary to feed and fix the plate material at the axis and Y-axis coordinate positions.

In this case, the final step is to use a gripping and retracting device that grips and pulls a part of the plate into a gripping and fixing device and a reference stopper, which will be described later. There wasn't.

C9 Problem to be Solved by the Invention The above-mentioned variation in the supply position of the plate material in the conventional apparatus is a problem to be solved by the present invention.

A solution to the d0 problem is to provide a plate gripping device for gripping the plate adjacent to the plate positioning and fixing device of the plate processing machine, and to provide the plate gripping device so that it can move forward and backward with respect to the plate positioning and fixing device. Solve.

00 Operation Since the device of the present invention can freely move forward and backward while gripping the plate relative to the plate positioning and fixing device, the feeding position of the plate can be accurately and reliably determined.

f. Example 111 The figure shows an example of a workbench 101 for laser-processing materials, and the plate material 3 to be processed is the frame 5 of the workbench 1 described above.
The final position is determined by a gripping and fixing device 7 provided on one side of the table, a reference stopper 9 provided on the other adjacent side (material feeding table described later), and a gripping and retracting device 11 provided diagonally between the two sides. Fixed.

That is, the X-axis direction line 15 passing through the stepped portion (not shown) of the fixed gripping claw 13 of the gripping and fixing device 7 and the Y-axis direction line 19 passing through the inner surface of the stopper 17 of the reference stopper 9 are not shown. These are the reference Y and X coordinates for numerical control of the cutting head.

Further, the gripping claw portion 21 of the gripping and retracting device 11 is shortened from the extended state as shown by the two-dot chain line, and the plate material 3 is set as the reference X.
It has moved to the Y coordinate position.

The lower frame 5 in FIG. 1 of this embodiment forms a material feeding table 23 with a wide rlJ in the X-axis direction, and below the material feeding table 23 is a large output motor 25 that circulates a chino belt (not shown). , and a small output motor 27 are provided.

Further, a groove 29 is provided slightly to the right of the center of the material feeding table 23 in FIGS. 1 and 2, and a gripping device 31 shown in FIGS. 6.7.8 is provided in this groove 29.

Magnet rollers 33.3 are provided on both sides of the groove portion 29 described above.
3 is provided, variable speed electric 1135 to Cheno 37
, intermediate sprocket shaft 39, sprocket 1-41.41
Rotationally driven through.

For non-magnetic plates, the pinch rollers 43, 43 shown in FIGS. 3 and 4 are driven by the fluid pressure cylinder 45 to move up and down, grip the plate 3, and carry it upward in FIG. 1.

Another variable speed motor 47 is provided on the opposite side of the variable speed motor 35 with the groove 29 mentioned above in between, and the rear end (lower end of the first rotation) of the groove 29 is connected from the output shaft sprocket 49 thereof.
A chino 53 is rotated around the sprocket shaft 51.

As is clear from FIG. 1, a cheno 57 is rotated around the sprocket shaft 55 provided at the front end of the groove 29 and the sprocket shaft 51 at the rear end mentioned above, and is rotated around the gripping device 31 shown in FIG. The gripping device 31 is driven by the electric motor 147 and moves forward and backward.

The gripping device 31 rides on a plurality of wheels 61 on the opening of a channel rail 59 made of, for example, a lipped section provided below the groove 29, and is driven by the chino 57 and can move freely in the X-axis direction. be.

Furthermore, the gripping device 31 has a swinging portion 65 equipped with a fixed gripping claw 63.
is attached to the lower part of the truck part 67 by a shaft 69, and this 1'
A movable gripping claw 71 is pivotally attached to the moving part 65 with a shaft pin 73 so as to be swingable.

A fluid pressure cylinder 75 is installed in the swinging portion 65 near the shaft 69, and its piston rod 77 is connected to a movable gripping claw 71.
It is attached to the free end of the shaft.

Also, near the swinging tip of the swinging section 65 (the left end in FIG. 6),
For example, a rod 79 is arranged so as to be able to freely swing around a shaft pin 81, and a bomb 83 is compressed between the rod 79 and the carriage portion 67.

Furthermore, a double nut 85 is provided at the lower end of the rod 79, so that unless the vicinity of the tip of the swinging portion 65 is under pressure,
As shown in FIG. 6, the fixed gripping claws 63 can be set to maintain a horizontal state.

Further, an idling roller 87 is provided on one side of the swinging portion 65, and a slope dog 89 is provided on a portion of the material feeding table 23 corresponding to this.

As shown in FIG. 1, a large number of free pole bearings 91 are installed on the top surface of the shipping table 23, and a first free pole bearing 91 is installed in front of the right magnet roller 33 to detect the tip or end of the plate material 3 to be carried in. A detection rA93 and a second detector 95 are provided.

Further, detectors 97, 99, and 101 for detecting the moving position of the gripping device 31 are also provided in the groove portion 29 described above.

9. Effects of the Invention Since the present invention is configured as described above, the plate material carried from the preceding processing device past the first detector to the magnet roller is driven by the variable speed electric motor. With the cooperation of magnetic rollers or pinch rollers, the end is moved past the second detector.

The gripping device, which was positioned below the surface of the material feeding table by the slope dog, then begins to move forward by the variable speed electric motor and reaches the end edge of the plate with the movable gripping claw raised by the hydraulic cylinder.

Thereafter, the gripping device grips the end of the plate and moves to a position beyond the Y-axis direction line, and the gripping and retracting device performs the work of positioning and fixing the plate.

Therefore, it is possible to automatically supply plate materials accurately and reliably to a plate processing machine incorporated in an assembly line, thereby solving the problems of the conventional apparatus.

It is also clear that design changes can be easily made without departing from the technical idea of the present invention.
