Description

[Detailed description of the invention] The present invention relates to a plate loading positioning device, and more specifically, when loading plates one by one into a numerically controlled plate processing machine automatically, the present invention This invention relates to a plate material carrying device that performs operations that include aligning and positioning two adjacent sides of a plate material.

When supplying material to a conventional numerically controlled plate processing machine, the plate is delivered flat on the table of the processing machine using a belt conveyor, etc., and the two sides are aligned with the reference origin of the numerically controlled machine. A device was used to move the plate by manually pressing it against a stopper or by moving a magnetic contact from below the pass line of the plate in the table of the plate processing machine. The method of using magnetic contacts sometimes uses the numerical control device of the plate processing machine, but it has many disadvantages when compared to fully automatic control as a plate processing line, such as installing a separate manual control device. It is.

This invention was made to overcome the above-mentioned disadvantages, and it does not affect the numerical control program in any way, and the plate material is aligned with the reference origin of the numerical control of the plate processing machine by fully automatic control of the plate material loading device. The purpose of the present invention is to provide a device that performs up to positioning, and preferred embodiments thereof will be described in detail below based on the drawings.

The board material carrying-in positioning device is generally indicated by 1 in FIG. 3, and is provided at the end of the board material carrying-in device shown by 3 in FIGS. 1 and 2 in the X direction. 5 is a plate processing machine, and in this embodiment, a numerically controlled turret type punching machine is shown.

As shown in FIG. 2, the board loading device 3 is guided by uneven parallel rails 7 and 9,
1, it is pulled by a circulating chain 13 and moves in the Y-axis direction. The X-axis direction is a little complicated, with the loading device outer frame 15 located at the outermost side, and the X-axis inside the outer frame.
There is an intermediate slide 17 that slides in the X-direction, and a slide base 19 that slides in the X-direction. Then,
The intermediate slide 17 directly reciprocates in the X direction,
The slide base 19 controls the movement of the intermediate slide 17 by a chain 23 that runs between a sprocket whose both ends are fixed to the outer frame and whose shaft is supported by the intermediate slide 17 and a sprocket whose shaft is supported by the slide base 19. Always move twice the distance.
A cross link mechanism 25 is attached to this slide base 19.
and a double-acting fluid pressure cylinder 27 as an example of a vertical movement device, the vacuum cup support plate 29 moves while maintaining a horizontal posture in the Z-axis direction (vertical direction).
is attached.

Note that the plate material loading device 3 shown in solid lines in FIG.
At the position shown, lower the vacuum cup base 29,
It picks up the topmost plate of the plates stacked on a pallet (not shown), lifts it up to the state shown in Figure 2, moves it in the Y-axis direction, and then horizontally moves it in the X-axis direction to process the plate. After the board is carried deep into the machine, it is lowered onto the table in a horizontal position.

In the above explanation, the imported plate material 31 is transferred to the plate material processing machine 5.
From the abutting line 37 (Y-axis direction reference line) of the clamp claw 35 of the numerically controlled conveyance device 33 and the inner line 41 (X-axis direction reference line) of the protrusion 39 provided protrudingly on the table, 3 plates each less than 10mm
It will be understood that it is carried in such that the two sides of 1 are located. The intersection of the Y-axis reference line 37 and the X-axis reference line 41 is the reference origin 43, which is commonly referred to in numerical control.

In the device of this embodiment, as shown in FIG.
One or more fixable vacuum cups 47 are provided, and the other vacuum cups 49 are switched from negative pressure to positive pressure, but only vacuum cup 47 is maintained at negative pressure, and the electric motor 11 described above is is driven at low speed in the Y-axis direction, and the double-acting fluid pressure cylinder 21 is driven at low speed to move the plate slightly in the X-axis direction. A sensor (not shown) detects the plate material at the X-axis reference line 4.
The clamp claw closes when it senses that the clamp claw 35 contacts the protrusion 39 that regulates the Y-axis reference line 37 and the contact portion of the clamp claw 35 that regulates the Y-axis reference line 37. During this small amount of movement, for example, the X-axis reference line may be reached quickly and the Y-axis reference line may be delayed. During this period, the vacuum cup 49 moves over the plate material. So that you can slide and shift,
In the example shown, 7 out of 9 vacuum cups in total.
The suction is released and positive pressure is applied to smooth the above-mentioned sliding.

After the clamp claws 35 have completed clamping the plate, the remaining vacuum cup 47 also releases its suction, and the work of positioning the plate to be carried in is completed, and there is no need to explain the movement back to the initial state.

The vacuum cup 47, which continues suction until the end, faces the elongated hole 45, and its position can be adjusted and fixed in the X-axis direction depending on the size of the plate material.
Since the position of 5 and the interval in the X-axis direction change, the plate is located at the center of the interval so that the plate can be moved equally with respect to the plurality of claws during the sliding period.

As detailed above, according to this device, the control mechanism of the loading device can automatically position the loaded plate without modifying or affecting the table or control device of the plate processing machine. It exhibits great features as a plate loading positioning device that is attached to a plate processing machine.

Although this example shows an example in which a vacuum cup is used, it is also possible to use a magnet for plate materials such as steel plates, and the direction of the elongated hole can also be adjusted.
They may be parallel to either the X or Y axis direction, or may be provided at an angle of 45 degrees in both directions, or any angle may be taken depending on the ratio of the long and short sides of the board. .
